coronavirus mutations | 40 | Discovery of a 382-nt deletion during the early evolution of SARS-CoV-2 | To date, the SARS-CoV-2 genome has been considered genetically more stable than SARS-CoV or MERS-CoV. Here we report a 382-nt deletion covering almost the entire open reading frame 8 (ORF8) of SARS-CoV-2 obtained from eight hospitalized patients in Singapore. The deletion also removes the ORF8 transcription-regulatory sequence (TRS), which in turn enhances the downstream transcription of the N gene. We also found that viruses with the deletion have been circulating for at least four weeks. During the SARS-CoV outbreak in 2003, a number of genetic variants were observed in the human population [1], and similar variation has since been observed across SARS-related CoVs in humans and bats. Overwhelmingly these viruses had mutations or deletions in ORF8, that have been associated with reduced replicative fitness of the virus [2]. This is also consistent with the observation that towards the end of the outbreak sequences obtained from human SARS cases possessed an ORF8 deletion that may be associated with host adaptation [1]. We therefore hypothesise that the major deletion revealed in this study may lead to an attenuated phenotype of SARS-CoV-2. | v5v9bjgs |
coronavirus mutations | 40 | SARS-CoV-2 and ORF3a: Non-Synonymous Mutations and Polyproline Regions | The effect of the rapid accumulation of non-synonymous mutations on the pathogenesis of SARS-CoV-2 is not yet known. To predict the impact of non-synonymous mutations and polyproline regions identified in ORF3a on the formation of B-cell epitopes and their role in evading the immune response, nucleotide and protein sequences of 537 available SARS-CoV-2 genomes were analyzed for the presence of non-synonymous mutations and polyproline regions. Mutations were correlated with changes in epitope formation. A total of 19 different non-synonymous amino acids substitutions were detected in ORF3a among 537 SARS-CoV-2 strains. G251V was the most common and identified in 9.9% (n=53) of the strains and was predicted to lead to the loss of a B-cell like epitope in ORF3a. Polyproline regions were detected in two strains (EPI_ISL_410486, France and EPI_ISL_407079, Finland) and affected epitopes formation. The accumulation of non-synonymous mutations and detected polyproline regions in ORF3a of SARS-CoV-2 could be driving the evasion of the host immune response thus favoring viral spread. Rapid mutations accumulating in ORF3a should be closely monitored throughout the COVID-19 pandemic. Importance At the surge of the COVID-19 pandemic and after three months of the identification of SARS-CoV-2 as the disease-causing pathogen, nucleic acid changes due to host-pathogen interactions are insightful into the evolution of this virus. In this paper, we have identified a set of non-synonymous mutations in ORF3a and predicted their impact on B-cell like epitope formation. The accumulation of non-synonymous mutations in ORF3a could be driving protein changes that mediate immune evasion and favoring viral spread. | tylwbnpl |

coronavirus mutations | 40 | Translation-associated mutational U-pressure in the first ORF of SARS-CoV-2 and other coronaviruses | Within four months of the ongoing COVID-19 pandemic caused by SARS-CoV-2, more than 250 nucleotide mutations have been detected in the ORF1 of the virus isolated from different parts of the globe. These observations open up an obvious question about the rate and direction of mutational pressure for further vaccine and therapeutics designing. In this study, we did a comparative analysis of ORF1a and ORF1b by using the first isolate (Wuhan strain) as the parent sequence. We observed that most of the nucleotide mutations are C to U transitions. The rate of synonymous C to U transitions is significantly higher than the rate of nonsynonymous ones, indicating negative selection on amino acid substitutions. Further, trends in nucleotide usage bias have been investigated in 49 coronaviruses species. A strong bias in nucleotide usage in fourfold degenerated sites towards uracil residues is seen in ORF1 of all the studied coronaviruses. A more substantial mutational U pressure is observed in ORF1a than in ORF1b owing to the translation of ORF1ab via programmed ribosomal frameshifting. Unlike other nucleotide mutations, mutational U pressure caused by cytosine deamination, mostly occurring in the RNA-plus strand, cannot be corrected by the proof-reading machinery of coronaviruses. The knowledge generated on the direction of mutational pressure during translation of viral RNA-plus strands has implications for vaccine and nucleoside analogue development for treating covid-19 and other coronavirus infections. | ug8xh52p |
coronavirus mutations | 40 | Evidence for strong mutation bias towards, and selection against, T/U content in SARS-CoV2: implications for attenuated vaccine design | Large-scale re-engineering of synonymous sites is a promising strategy to generate attenuated viruses for vaccines. Attenuation typically relies on de-optimisation of codon pairs and maximization of CpG dinculeotide frequencies. So as to formulate evolutionarily-informed attenuation strategies, that aim to force nucleotide usage against the estimated direction favoured by selection, here we examine available whole-genome sequences of SARS-CoV2 to infer patterns of mutation and selection on synonymous sites. Analysis of mutational profiles indicates a strong mutation bias towards T with concomitant selection against T. Accounting for dinucleotide effects reinforces this conclusion, observed TT content being a quarter of that expected under neutrality. A significantly different mutational profile at CDS sites that are not 4-fold degenerate is consistent with contemporaneous selection against T mutations more widely. Although selection against CpG dinucleotides is expected to drive synonymous site G+C content below mutational equilibrium, observed G+C content is slightly above equilibrium, possibly because of selection for higher expression. Consistent with gene-specific selection against CpG dinucleotides, we observe systematic differences of CpG content between SARS-CoV2 genes. We propose an evolutionarily informed gene-bespoke approach to attenuation that, unusually, seeks to increase usage of the already most common synonymous codons. Comparable analysis of H1N1 and Ebola finds that GC3 deviated from neutral equilibrium is not a universal feature, cautioning against generalization of results. | w8ylmbey |
coronavirus mutations | 40 | SARS-CoV-2 mutations altering regulatory properties: deciphering host’s and virus’s perspectives | Since the first recorded case of the SARS-CoV-2, it has acquired several mutations in its genome while spreading throughout the globe. However, apart from some changes in protein coding, functional importance of these mutations in disease pathophysiology are still largely unknown. In this study, we investigated the significance of these mutations both from the host’s and virus’s perspective by analyzing the host miRNA binding and virus’s internal ribosome entry site (IRES), respectively. Strikingly, we observed that due to the acquired mutations, host miRNAs bind differently compared to the reference; where few of the miRNAs lost and few gained the binding affinity for targeting the viral genome. Moreover, functional enrichment analysis suggests that targets of both of these gained and lost miRNAs might be involved in various host immune signaling pathways. Also, we sought to shed some insights on the impacts of mutations on the IRES structure of SARS-CoV-2. Remarkably, we detected that three particular mutations in the IRES can disrupt its secondary structure which can further make the virus less functional. These results could be valuable in exploring the functional importance of the mutations of SARS-CoV-2 and could provide novel insights into the differences observed different parts of the world. | 6f1y5hhv |
coronavirus mutations | 40 | Two mutations P/L and Y/C in SARS-CoV-2 helicase domain exist together and influence helicase RNA binding | RNA helicases play pivotal role in RNA replication by catalysing the unwinding of complex RNA duplex structures into single strands in ATP/NTP dependent manner. SARS coronavirus 2 (SARS-CoV-2) is a single stranded positive sense RNA virus belonging to the family Coronaviridae. The viral RNA encodes non structural protein Nsp13 or the viral helicase protein that helps the viral RNA dependent RNA polymerase (RdRp) to execute RNA replication by unwinding the RNA duplexes. In this study we identified a novel mutation at position 541of the helicase where the tyrosine (Y) got substituted with cytosine (C). We found that Y541C is a destabilizing mutation increasing the molecular flexibility and leading to decreased affinity of helicase binding with RNA. Earlier we had reported a mutation P504L in the helicase protein for which had not performed RNA binding study. Here we report that P504L mutation leads to increased affinity of helicase RNA interaction. So, both these mutations have opposite effects on RNA binding. Moreover, we found a significant fraction of isolate population where both P504L and Y541C mutations were co-existing. | bx7k42rn |
coronavirus mutations | 40 | SARS-CoV2 envelope protein: Non-synonymous mutations and its consequences | In the NCBI database, as on June 6, 2020, total number of available complete genome sequences of SARS-CoV2 across the world is 3617. The envelope protein of SARS-CoV2 possesses several non-synonymous mutations over the transmembrane domain and (C)-terminus in 15 (0.414%) genomes among 3617 available SARS-CoV2 genomes. More precisely, it is to be mentioned that 10(0.386%) out of 2588 genomes from the USA, 3(0.806%) from Asia, 1 (0.348%) from Europe and 1 (0.274%) from Oceania contain the missense mutations over the envelope proteins of SARS-CoV2 genomes. The C-terminus motif DLLV has been changed to DFLV and YLLV in the proteins QJR88103 (Australia: Victoria) and QKI36831 (China: Guangzhou) respectively, which might affect the binding of this motif with the host protein PALS1. | phl6ibbv |
coronavirus mutations | 40 | Conserved High Free Energy Sites in Human Coronavirus Spike Glycoprotein Backbones | Methods previously developed by the author are applied to uncover several sites of interest in the spike glycoproteins of all known human coronaviruses (hCoVs), including SARS-CoV-2 that causes COVID-19. The sites comprise three-dimensional neighborhoods of peptides characterized by four key properties: (1) they pinpoint regions of high free energy in the backbone whose obstruction might interrupt function; (2) by their very definition, they occur rarely in the universe of all gene-encoded proteins that could obviate host response to compounds designed for their interference; (3) they are common to all known hCoV spikes, possibly retaining activity in light of inevitable viral mutation; and (4) they are exposed in the molecular surface of the glycoprotein. These peptides in SARS-CoV-2 are given by the triples of residues (131, 117, 134), (203, 227, 228), and (1058, 730, 731) in its spike. | 8ha8qv5o |
coronavirus mutations | 40 | An overview of the genetic variations of the SARS-CoV-2 genomes isolated in Southeast Asian countries | Monitoring the mutation dynamics of human severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical in understanding its infectivity, virulence and pathogenicity for development of a vaccine. In an "age of mobility", the pandemic highlights the importance and vulnerability of regionalisation and labour market interdependence in Southeast Asia. We intend to characterise the genetic variability of viral populations within the region to provide preliminary information for regional surveillance in the future. By analysing 142 complete genomes from South East Asian (SEA) countries, we identified three central variants distinguished by nucleotide and amino acid changes. | ewpfxpw2 |
coronavirus mutations | 40 | Comparison five primer sets from different genome region of covid-1for detection of virus infection by conventional rt-pcr | Background and Objectives: The new beta-coronavirus, which caused Severe Acute Respiratory Coronavirus-2 Syndrome (SARS-CoV-2), a major respiratory outbreak in Wuhan, China in December 2019, is now prevalent in many countries around the world Identifying PCR-based viruses is a well-known and relatively stable protocol Unfortunately, the high mutation rates may lead to widespread changes in viral nucleic acid sequences, and so using specific primers for PCR can be recom-mended In this study, we evaluated the power of a conventional RT-PCR to detect SARS-CoV-2 RNA among the five set primer sets Materials and Methods: The five genomic regions of the Coronavirus SARS-2 virus including Nucleocapsids (N), Enve-lope (E), RNA depended RNA Polymerase (RdRp), ORF1ab and Spike (S) were selected for primer designing A conventional RT-PCR was performed to compare sensitivity, specificity and other analytical characteristics of primers designed against two Real Time PCR commercial kits Results: The result of the comparative analysis showed that the ORF1ab, N and RdRp primers had a sensitivity, specificity and positive predictive value higher than other primers A significant difference in the analytical sensitivity between the studied primer sets in RT-PCR kits was observed Conclusion: In this study, the ORF1ab, Nucleocapsid and RdRp regions have the best primers for identifying the SARS-CoV-2 RNA between different genes that have been suggested | 9c449ygv |

coronavirus mutations | 40 | Overwhelming mutations or SNPs of SARS-CoV-2: A point of caution | The morbidity of SARS-CoV-2 (COVID-19) is reaching 3 Million landmark causing and a serious public health concern globally and it is enigmatic how several antiviral and antibody treatments were not effective in the different period across the globe. With the drastic increasing number of positive cases around the world WHO raised the importance in the assessment of the risk of spread and understanding genetic modifications that could have occurred in the SARS-CoV-2. Using all available deep sequencing data of complete genome from all over the world (NCBI repository), we identified several hundreds of point mutations or SNPs in SARS-CoV-2 all across the genome. This could be the cause for the constant change and differed virulence with an increase in mortality and morbidity. Among the 12 different countries (one sequence from each country) with complete genome sequencing data, we noted the 47 key point mutations or SNPs located along the entire genome that might have impact in the virulence and response to different antivirals against SARS-CoV-2. In this regard, key viral proteins of spike glycoprotein, Nsp1, RdRp and the ORF8 region got heavily mutated within these 3 months via person-to-person passage. We also discuss what could be the possible cause of this rapid mutation in the SARS-CoV-2. | j8sg5n5g |
coronavirus mutations | 40 | Identification of nsp1 gene as the target of SARS-CoV-2 real-time RT-PCR using nanopore whole-genome sequencing | Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the coronavirus disease 2019 (COVID-19) pandemic. Accurate detection of SARS-CoV-2 using molecular assays is critical for patient management and the control of the COVID-19 pandemic. However, there is an increasing number of SARS-CoV-2 viruses with mutations at the primer or probe binding sites, and these mutations may affect the sensitivity of currently available real-time reverse transcription-polymerase chain reaction (RT-PCR) assays targeting the nucleocapsid (N), envelope (E), and open reading frame 1a or 1b genes. Using sequence-independent single-primer amplification and nanopore whole-genome sequencing, we have found that the nonstructural protein 1 (nsp1) gene, located at the 5' end of the SARS-CoV-2 genome, was highly expressed in the nasopharyngeal or saliva specimens of 9 COVID-19 patients of different clinical severity. Based on this finding, we have developed a novel nsp1 real-time RT-PCR assay. The primers and probes are highly specific for SARS-CoV-2. Validation with 101 clinical specimens showed that our nsp1 RT-PCR assay has a sensitivity of 93.1% (95% confidence interval [CI]: 86.2%-97.2%), which was similar to those of N and E gene RT-PCR assays. The diagnostic specificity was 100% (95% CI: 92.9%-100%). The addition of nsp1 for multitarget detection of SARS-CoV-2 can avoid false-negative results due to mutations at the primers/probes binding sites of currently available RT-PCR assays. | 9gjv37dh |

coronavirus mutations | 40 | Epidemiological, clinical, and virological characteristics of 465 hospitalized cases of coronavirus disease 2019 (COVID-19) from Zhejiang province in China | BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the associated coronavirus disease (COVID-19) have spread throughout China. Previous studies predominantly focused on its place of origin, Wuhan, causing over estimation of the disease severity due to selection bias. We analyzed 465 confirmed cases in Zhejiang province to determine the epidemiological, clinical, and virological characteristics of COVID-19. METHODS: Epidemiological, demographic, clinical, laboratory, and management data from qRT-PCR confirmed COVID-19 patients from January 17, 2020, to January 31, 2020, were collected, followed by multivariate logistic regression analysis for independent predictors of severe/critical-type COVID-19 and bioinformatic analysis for features of SARS-CoV-2 from Zhejiang province. RESULTS: Among 465 COVID-19 patients, median age was 45 years, while hypertension, diabetes, and chronic liver disease were the most common comorbidities. History of exposure to the epidemic area was present in 170 (36.56%) and 185 (39.78%) patients were clustered in 77 families. Severe/critical-type of COVID-19 developed in 49 (10.54%) patients. Fever and cough were the most common symptoms, while diarrhea/vomiting was reported in 58 (12.47%) patients. Multivariate analysis revealed eight risk factors for severe/critical COVID-19. Glucocorticoids and antibiotics were administered to 60 (12.90%) and 218(46.88%) patients, respectively. Bioinformatics showed four single amino acid mutations and one amino acid position loss in SARS-CoV-2 from Zhejiang province, with more similarity to humans than to viruses. CONCLUSIONS: SARS-CoV-2 showed virological mutations and more human transmission in Zhejiang province, indicating considerable epidemiological and clinical changes. Caution in glucocorticoid and antibiotics use is advisable. | uiy0hrrg |
coronavirus mutations | 40 | Mutations can reveal how the coronavirus moves—but they’re easy to overinterpret ;Science ;AAAS | mmediately after Christian Drosten published a genetic sequence of the novel coronavirus online on 28 February, he took to Twitter to issue a warning As the virus has raced around the world, more than 350 genome sequences have been shared on the online platform GISAID They hold clues to how the new virus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is spreading and evolving But because the sequences represent a tiny fraction of cases and show few telltale differences, they are easy to overinterpret, as Drosten realized A virologist at the Charité University Hospital in Berlin, he had sequenced the virus from a German patient infected with COVID-19 in Italy The genome looked similar to that of a virus found in a patient in Munich, the capital of Bavaria, more than 1 month earlier;both shared three mutations not seen in early sequences from China Drosten realized this could give rise to the idea that the Italian outbreak was “seeded” by the one in Bavaria, which state public health officials said had been quashed by tracing and quarantining all contacts of the 14 confirmed cases But he thought it was just as likely that a Chinese variant carrying the three mutations had taken independent routes to both countries The newly sequenced genome “is not sufficient to claim a link between Munich and Italy,” Drosten tweeted | wk63bmgn |
coronavirus mutations | 40 | Rampant CâU Hypermutation in the Genomes of SARS-CoV-2 and Other Coronaviruses: Causes and Consequences for Their Short- and Long-Term Evolutionary Trajectories | The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has motivated an intensive analysis of its molecular epidemiology following its worldwide spread. To understand the early evolutionary events following its emergence, a data set of 985 complete SARS-CoV-2 sequences was assembled. Variants showed a mean of 5.5 to 9.5 nucleotide differences from each other, consistent with a midrange coronavirus substitution rate of 3 × 10-4 substitutions/site/year. Almost one-half of sequence changes were CâU transitions, with an 8-fold base frequency normalized directional asymmetry between CâU and UâC substitutions. Elevated ratios were observed in other recently emerged coronaviruses (SARS-CoV, Middle East respiratory syndrome [MERS]-CoV), and decreasing ratios were observed in other human coronaviruses (HCoV-NL63, -OC43, -229E, and -HKU1) proportionate to their increasing divergence. CâU transitions underpinned almost one-half of the amino acid differences between SARS-CoV-2 variants and occurred preferentially in both 5' U/A and 3' U/A flanking sequence contexts comparable to favored motifs of human APOBEC3 proteins. Marked base asymmetries observed in nonpandemic human coronaviruses (U â« A > G â« C) and low G+C contents may represent long-term effects of prolonged CâU hypermutation in their hosts. The evidence that much of sequence change in SARS-CoV-2 and other coronaviruses may be driven by a host APOBEC-like editing process has profound implications for understanding their short- and long-term evolution. Repeated cycles of mutation and reversion in favored mutational hot spots and the widespread occurrence of amino acid changes with no adaptive value for the virus represent a quite different paradigm of virus sequence change from neutral and Darwinian evolutionary frameworks and are not incorporated by standard models used in molecular epidemiology investigations.IMPORTANCE The wealth of accurately curated sequence data for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), its long genome, and its low substitution rate provides a relatively blank canvas with which to investigate effects of mutational and editing processes imposed by the host cell. The finding that a large proportion of sequence change in SARS-CoV-2 in the initial months of the pandemic comprised CâU mutations in a host APOBEC-like context provides evidence for a potent host-driven antiviral editing mechanism against coronaviruses more often associated with antiretroviral defense. In evolutionary terms, the contribution of biased, convergent, and context-dependent mutations to sequence change in SARS-CoV-2 is substantial, and these processes are not incorporated by standard models used in molecular epidemiology investigations. | 14pgap3r |

coronavirus mutations | 40 | Implications of SARS-CoV-2 Mutations for Genomic RNA Structure and Host microRNA Targeting | The SARS-CoV-2 virus is a recently-emerged zoonotic pathogen already well adapted to transmission and replication in humans. Although the mutation rate is limited, recently introduced mutations in SARS-CoV-2 have the potential to alter viral fitness. In addition to amino acid changes, mutations could affect RNA secondary structure critical to viral life cycle, or interfere with sequences targeted by host miRNAs. We have analysed subsets of genomes from SARS-CoV-2 isolates from around the globe and show that several mutations introduce changes in Watson-Crick pairing, with resultant changes in predicted secondary structure. Filtering to targets matching miRNAs expressed in SARS-CoV-2-permissive host cells, we identified ten separate target sequences in the SARS-CoV-2 genome; three of these targets have been lost through conserved mutations. A genomic site targeted by the highly abundant miR-197-5p, overexpressed in patients with cardiovascular disease, is lost by a conserved mutation. Our results are compatible with a model that SARS-CoV-2 replication within the human host is constrained by host miRNA defences. The impact of these and further mutations on secondary structures, miRNA targets or potential splice sites offers a new context in which to view future SARS-CoV-2 evolution, and a potential platform for engineering conditional attenuation to vaccine development, as well as providing a better understanding of viral tropism and pathogenesis. | eri92ki6 |
coronavirus mutations | 40 | A comprehensive analysis of genome composition and codon usage patterns of emerging coronaviruses | An outbreak of atypical pneumonia caused by a novel Betacoronavirus (ßCoV), named SARS-CoV-2 has been declared a public health emergency of international concern by the World Health Organization. In order to gain insight into the emergence, evolution and adaptation of SARS-CoV-2 viruses, a comprehensive analysis of genome composition and codon usage of ßCoV circulating in China was performed. A biased nucleotide composition was found for SARS-CoV-2 genome. This bias in genomic composition is reflected in its codon and amino acid usage patterns. The overall codon usage in SARS-CoV-2 is similar among themselves and slightly biased. Most of the highly frequent codons are A- and U-ending, which strongly suggests that mutational bias is the main force shaping codon usage in this virus. Significant differences in relative synonymous codon usage frequencies among SARS-CoV-2 and human cells were found. These differences are due to codon usage preferences. | 3r66vrv0 |
coronavirus mutations | 40 | Evidence for mutations in SARS-CoV-2 Italian isolates potentially affecting virus transmission | Italy is the first western country suffering heavy severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and disease impact after coronavirus disease-2019 pandemia started in China. Even though the presence of mutations on spike glycoprotein and nucleocapsid in Italian isolates has been reported, the potential impact of these mutations on viral transmission has not been evaluated. We have compared SARS-CoV-2 genome sequences from Italian patients with virus sequences from Chinese patients. We focussed upon three nonsynonymous mutations of genes coding for S(one) and N (two) viral proteins present in Italian isolates and absent in Chinese ones, using various bioinformatics tools. Amino acid analysis and changes in three-dimensional protein structure suggests the mutations reduce protein stability and, particularly for S1 mutation, the enhanced torsional ability of the molecule could favor virus binding to cell receptor(s). This theoretical interpretation awaits experimental and clinical confirmation. | 4z6wcmxq |
coronavirus mutations | 40 | SARS-CoV-2 viral spike G614 mutation exhibits higher case fatality rate | AIM: The COVID-19 pandemic is caused by infection with the SARS-CoV-2 virus. The major mutation detected to date in the SARS-CoV-2 viral envelope spike protein, which is responsible for virus attachment to the host and is also the main target for host antibodies, is a mutation of an aspartate (D) at position 614 found frequently in Chinese strains to a glycine (G). We sought to infer health impact of this mutation. RESULT: Increased case fatality rate correlated strongly with the proportion of viruses bearing G614 on a country by country basis. The amino acid at position 614 occurs at an internal protein interface of the viral spike, and the presence of G at this position was calculated to destabilise a specific conformation of the viral spike, within which the key host receptor binding site is more accessible. CONCLUSION: These results imply that G614 is a more pathogenic strain of SARS-CoV-2, which may influence vaccine design. The prevalence of this form of the virus should also be included in epidemiologic models predicting the COVID-19 health burden and fatality over time in specific regions. Physicians should be aware of this characteristic of the virus to anticipate the clinical course of infection. | 273ppceg |
coronavirus mutations | 40 | Tracing New Clinical Manifestations in Patients with COVID-19 in Chile and Its Potential Relationship with the SARS-CoV-2 Divergence | Purpose of Review: In this review, we discuss the current implications of the changing genomic epidemiology of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), etiological agent of the Coronavirus Disease 2019 (COVID-19) and its potential relationship with the change of clinical manifestations in patients with confirmed infection. Recent Findings: Over the course of the current pandemic, the virus has been found more diverse in new countries. Simultaneously, also new clinical manifestations are observed, particularly more prominent gastrointestinal and neurological findings. Summary: SARS-CoV-2/COVID-19 is changing not only its epidemiology, but also its genomic diversity and clinical manifestations, both aspects coupled, needs to be considered in the study of this ongoing pandemic. | b1cruunn |
coronavirus mutations | 40 | Evidence for host-dependent RNA editing in the transcriptome of SARS-CoV-2 | The COVID-19 outbreak has become a global health risk, and understanding the response of the host to the SARS-CoV-2 virus will help to combat the disease. RNA editing by host deaminases is an innate restriction process to counter virus infection, but it is not yet known whether this process operates against coronaviruses. Here, we analyze RNA sequences from bronchoalveolar lavage fluids obtained from coronavirus-infected patients. We identify nucleotide changes that may be signatures of RNA editing: adenosine-to-inosine changes from ADAR deaminases and cytosine-to-uracil changes from APOBEC deaminases. Mutational analysis of genomes from different strains of Coronaviridae from human hosts reveals mutational patterns consistent with those observed in the transcriptomic data. However, the reduced ADAR signature in these data raises the possibility that ADARs might be more effective than APOBECs in restricting viral propagation. Our results thus suggest that both APOBECs and ADARs are involved in coronavirus genome editing, a process that may shape the fate of both virus and patient. | 40i8ot5h |
coronavirus mutations | 40 | Targeting the Dimerization of the Main Protease of Coronaviruses: A Potential Broad-Spectrum Therapeutic Strategy | A new coronavirus (CoV) caused a pandemic named COVID-19, which has become a global health care emergency in the present time. The virus is referred to as SARS-CoV-2 (severe acute respiratory syndrome-coronavirus-2) and has a genome similar (â¼82%) to that of the previously known SARS-CoV (SARS coronavirus). An attractive therapeutic target for CoVs is the main protease (Mpro) or 3-chymotrypsin-like cysteine protease (3CLpro), as this enzyme plays a key role in polyprotein processing and is active in a dimeric form. Further, Mpro is highly conserved among various CoVs, and a mutation in Mpro is often lethal to the virus. Thus, drugs targeting the Mpro enzyme significantly reduce the risk of mutation-mediated drug resistance and display broad-spectrum antiviral activity. The combinatorial design of peptide-based inhibitors targeting the dimerization of SARS-CoV Mpro represents a potential therapeutic strategy. In this regard, we have compiled the literature reports highlighting the effect of mutations and N-terminal deletion of residues of SARS-CoV Mpro on its dimerization and, thus, catalytic activity. We believe that the present review will stimulate research in this less explored yet quite significant area. The effect of the COVID-19 epidemic and the possibility of future CoV outbreaks strongly emphasize the urgent need for the design and development of potent antiviral agents against CoV infections. | 8bzu2gn0 |
coronavirus mutations | 40 | Implications of altered replication fidelity on the evolution and pathogenesis of coronaviruses | RNA virus evolution results from viral replication fidelity and mutational robustness in combination with selection. Recent studies have confirmed the impact of increased fidelity on RNA virus replication and pathogenesis; however, the impact of decreased fidelity is less defined. Coronaviruses have the largest RNA genomes, and encode an exoribonuclease activity that is required for high-fidelity replication. Genetically stable exoribonuclease mutants will allow direct testing of viral mutational tolerance to RNA mutagens and other selective pressures. Recent studies support the hypothesis that coronavirus replication fidelity may result from a multi-protein complex, suggesting multiple pathways to disrupt or alter virus fidelity and diversity, and attenuate pathogenesis. | ac38yvcn |
coronavirus mutations | 40 | Genetic variability of human angiotensin‐converting enzyme 2 (hACE2) among various ethnic populations | BACKGROUND: There appears to be large regional variation for susceptibility, severity, and mortality for COVID‐19 infections. Numerous potential factors could explain the wide variability in the number of infections and death among the countries. We examined genetic differences in the human angiotensin‐converting enzyme 2 (hACE2) gene, as its receptor serves as a cellular entry for SARS‐CoV‐2. At present, there is a paucity of data regarding the differences for ACE2 polymorphisms and expression levels between ethnicities. METHODS: We compared the allele frequency of mutations between European and East Asians. Molecular dynamic simulation were performed to investigate the influences of significant mutant on protein structure. The binding free energies were calculated between S protein and hACE2. We also examined hACE2 gene expression in eight global populations from HapMap3. RESULTS: Four missense mutations showed significant minor allele frequency difference between Asians and Caucasians. Molecular dynamic demonstrated that two of these variants (K26R and I468V) may affect binding characteristics between S protein of the virus and hACE2 receptor. We also noted marginal differences in gene expression for some populations in HapMap3 as compared to the Chinese population. CONCLUSION: Our studies reveal subtle changes in the genetics of hACE2 between human populations, but the magnitude of the difference was small and the significance is not clear in the absence of further in vitro and functional studies. | 48opcqzs |

COVID-19 in African-Americans | 41 | COVID-19 Pandemic: Exacerbating Racial/Ethnic Disparities in Long-Term Services and Supports. | What services are available and where racial and ethnic minorities receive long-term services and supports (LTSS) have resulted in a lower quality of care and life for racial/ethnic minority users. These disparities are only likely to worsen during the COVID-19 pandemic, as the pandemic has disproportionately affected racial and ethnic minority communities both in the rate of infection and virus-related mortality. By examining these disparities in the context of the pandemic, we bring to light the challenges and issues faced in LTSS by minority communities with regard to this virus as well as the disparities in LTSS that have always existed. | fxtmdpds |
COVID-19 in African-Americans | 41 | Seizing the Moment: Policy Advocacy to End Mass Incarceration in the Time of COVID-19. | The mass human and economic casualties wrought by the COVID-19 pandemic laid bare the deep inequities at the base of the disproportionate losses and suffering experienced by diverse U.S. populations. But the urgency and enormity of unmet needs requiring bold policy action also provided a unique opportunity to learn from and partner with community-based organizations that often are at the frontlines of such work. Following a review of Kingdon's model of the policy-making process, we illustrate how a partnership in a large California county navigated the streams in the policy-making process and used the window of opportunity provided by the pandemic to address a major public health problem: the incarceration of over 2 million people, disproportionately African American and Latinx, in overcrowded, unsafe jails, prisons, and detention centers. We highlight tactics and strategies used, challenges faced, and implications for health educators as policy advocates during and beyond the pandemic. | fe1v252b |
COVID-19 in African-Americans | 41 | Social Vulnerability and Racial Inequality in COVID-19 Deaths in Chicago. | Although the current COVID-19 crisis is felt globally, at the local level, COVID-19 has disproportionately affected poor, highly segregated African American communities in Chicago. To understand the emerging pattern of racial inequality in the effects of COVID-19, we examined the relative burden of social vulnerability and health risk factors. We found significant spatial clusters of social vulnerability and risk factors, both of which are significantly associated with the increased COVID-19-related death rate. We also found that a higher percentage of African Americans was associated with increased levels of social vulnerability and risk factors. In addition, the proportion of African American residents has an independent effect on the COVID-19 death rate. We argue that existing inequity is often highlighted in emergency conditions. The disproportionate effects of COVID-19 in African American communities are a reflection of racial inequality and social exclusion that existed before the COVID-19 crisis. | gn8uwuca |

COVID-19 in African-Americans | 41 | Racial Disparities in COVID-19 Deaths Reveal Harsh Truths About Structural Inequality in America. | The Coronavirus disease 2019 (COVID-19) pandemic has unveiled the stark racial disparities that are present in United States (US) and other developed countries today. In recent weeks, several states have released demographic data that highlights the disproportionate rate of COVID-19 infections in racial/ethnic minorities1 . These disparities are likely a result of the structural inequities that minorities face due to factors such as racism, neighborhood segregation, income, housing and education inequality, and poor access to medical care. | a2kjjsq1 |
COVID-19 in African-Americans | 41 | Social Workers Must Address Intersecting Vulnerabilities among Noninstitutionalized, Black, Latinx, and Older Adults of Color during the COVID-19 Pandemic. | Scant attention has been paid to intersecting vulnerabilities experienced by Black, Latinx, and older adults of color (BLOAC) that increase COVID-19 related risks. Structural inequities have resulted in disproportionate rates of chronic conditions and limited access to care. Media coverage, focused on COVID-19 mortality among institutionalized older adults (OA), has overlooked community-dwelling OA, leaving their unique risks unaddressed in research and intervention efforts. Key vulnerabilities impacting noninstitutionalized BLOAC exacerbating adverse health outcomes during COVID-19 are discussed, and recommendations are given for gerontological social work (GSW) education, training, and practice to meet the needs of BLOAC during the COVID-19 pandemic. | ivjt0eml |

COVID-19 in African-Americans | 41 | COVID-19–Associated Collapsing Focal Segmental Glomerulosclerosis: A Report of 2 Cases | Collapsing glomerulopathy is an aggressive form of focal segmental glomerulosclerosis with diverse etiologies The presence of APOL1 high risk genotype is a major risk factor for collapsing glomerulopathy in African Americans Coronavirus disease 2019 (COVID-19) is an emerging pandemic with predominant respiratory manifestations However, kidney involvement is being frequently noted and is associated with higher mortality Currently kidney pathology data in COVID-19 are scant and mostly come from postmortem findings We report two African American patients who developed acute kidney injury and proteinuria in temporal association with COVID-19 Kidney biopsies showed collapsing glomerulopathy, endothelial tubuloreticular inclusions, and acute tubular injury, without evidence by electron microscopy or SARS-CoV-2 ISH of viral infection of kidney cells Both patients had APOL1 high risk genotype We propose that collapsing glomerulopathy represents a novel manifestation of COVID-19 especially in people of African descent with APOL1 risk alleles | 952w7vx5 |
COVID-19 in African-Americans | 41 | Blacks/African Americans are 5 Times More Likely to Develop COVID-19: Spatial Modeling of New York City ZIP Code-level Testing Results | Introduction. The population and spatial characteristics of COVID-19 infections are poorly understood, but there is increasing evidence that in addition to individual clinical factors, demographic, socioeconomic and racial characteristics play an important role. Methods. We analyzed positive COVID-19 testing results counts within New York City ZIP Code Tabulation Areas (ZCTA) with Bayesian hierarchical Poisson spatial models using integrated nested Laplace approximations. Results. Spatial clustering accounted for approximately 32% of the variation in the data, with hot spots in all five boroughs. Spatial risk did not correspond precisely to population-based rates of positive tests. The strongest univariate association with positive testing rates was the proportion of residents in a ZIP Code Tabulation Area with Chronic Obstructive Pulmonary Disease (COPD). For every one unit increase in a scaled standardized measure of COPD in a community, there was an approximate 8-fold increase in the risk of a positive COVID-19 test in a ZCTA (Incidence Density Ratio = 8.2, 95% Credible Interval 3.7, 18.3). The next strongest association was with the proportion of Black and African American residents, for which there was a nearly five-fold increase in the risk of a positive COVID-19 test. (IDR = 4.8, 95% Cr I 2.4, 9.7). Increases in the proportion of residents older than 65, housing density and the proportion of residents with heart disease were each associated with an approximate doubling of risk. In a multivariable model including estimates for age, COPD, heart disease, housing density and Black/African American race, the only variables that remained associated with positive COVID-19 testing with a probability greater than chance were the proportion of Black/African American residents and proportion of older persons. Conclusions. The population and spatial patterns of COVID-19 infections differ by race, age, physical environment and health status. Areas with large proportions of Black/African American residents are at markedly higher risk that is not fully explained by characteristics of the environment and pre-existing conditions in the population. | crqvdk4k |
COVID-19 in African-Americans | 41 | Outcomes and Cardiovascular Comorbidities in a Predominantly African-American Population with COVID-19 | Importance: Racial disparities in COVID-19 outcomes have been amplified during this pandemic and reports on outcomes in African-American (AA) populations, known to have higher rates of cardiovascular (CV) comorbidities, remain limited. Objective: To examine prevalence of comorbidities, rates of hospitalization and survival, and incidence of CV manifestations of COVID-19 in a predominantly AA population in south metropolitan Chicago. Design, Setting, Participants: This was an observational cohort study of COVID-19 patients encountered from March 16 to April 16, 2020 at the University of Chicago. Deidentified data were obtained from an institutional data warehouse. Group comparisons and logistic regression modeling based on baseline demographics, clinical characteristics, laboratory and diagnostic testing was performed. Exposures: COVID-19 was diagnosed by nasopharyngeal swab testing and clinical management was at the discretion of treating physicians. Main Outcomes and Measures: Primary outcomes were hospitalization and in-hospital mortality, and secondary outcomes included incident CV manifestations of COVID-19 in the context of overall cardiology service utilization. Results: During the 30 day study period, 1008 patients tested positive for COVID-19 and 689 had available encounter data. Of these, 596 (87%) were AA and 356 (52%) were hospitalized, of which 319 (90%) were AA. Age > 60 years, tobacco use, BMI >40 kg/m2, diabetes mellitus (DM), insulin use, hypertension, chronic kidney disease, coronary artery disease (CAD), and atrial fibrillation (AF) were more common in hospitalized patients. Age > 60 years, tobacco use, CAD, and AF were associated with greater risk of in-hospital mortality along with several elevated initial laboratory markers including troponin, NT-proBNP, blood urea nitrogen, and ferritin. Despite this, cardiac manifestations of COVID-19 were uncommon, coincident with a 69% decrease in cardiology service utilization. For hospitalized patients, median length of stay was 6.2 days (3.4-11.9 days) and mortality was 13%. AA patients were more commonly hospitalized, but without increased mortality. Conclusions and Relevance: In this AA-predominant experience from south metropolitan Chicago, CV comorbidities and chronic diseases were highly prevalent and associated with increased hospitalization and mortality. Insulin-requiring DM and CKD emerged as novel predictors for hospitalization. Despite the highest rate of comorbidities reported to date, CV manifestations of COVID-19 and mortality were relatively low. The unexpectedly low rate of mortality merits further study. | 4f6h7agt |
COVID-19 in African-Americans | 41 | Impact of COVID-19 on 2020 US life expectancy for the Black and Latino populations | The Black and Latino populations have experienced a disproportionate burden of COVID-19 morbidity and mortality, reflecting persistent structural inequalities that increase risk of exposure to COVID-19 and risk of death for those infected. According to the National Center for Health Statistics, as of July 4, 2020, deaths to Black and Latino individuals comprised 23% and 17%, respectively, of the approximately 115,000 COVID-19 deaths. COVID-19 mortality is likely to result in a larger decline in life expectancy during 2020 than the US has experienced for decades as well as a particularly large reduction for Black and Latino individuals. We estimate life expectancy at birth and at age 65 for 2020, by race and ethnicity, using four scenarios of deaths-one in which the COVID-19 pandemic had not occurred and three including COVID-19 mortality projections produced by the Institute for Health Metrics and Evaluation. Our most likely estimate indicates a reduction in life expectancy at birth greater than 1.5 years for both the Black and Latino populations, which is one year larger than the reduction for whites. This would imply that the Black-white gap would increase by 30%, from 3.6 to 4.7 years, thereby eliminating progress made in reducing this differential since 2008 and reversing an overall trend of steeper mortality declines among the Black population since the early 1990s. Latinos, who have consistently experienced lower mortality than whites (a phenomenon known as the Latino or Hispanic paradox), would see their survival advantage decline by 36%, equivalent to its magnitude in 2006. | bjvg2ivr |

COVID-19 in African-Americans | 41 | Disproportionate COVID-19 Related Mortality Amongst African Americans in Four Southern States in the United States | Background African American have been severely affected by COVID-19 noted with the rising mortality rates within the African American community. Health disparities, health inequities and issues with systemic health access are some of the pre-existing issues African American were subjected to within the southern states in the United States. Second, social distancing is a critical non-pharmacological intervention to reduce the spread of COVID-19. However, social distancing was not practical and presented a challenge within the African American community, specifically, in the southern states. Objective This article assesses the effect of COVID-19 on African American in the southern states. Methodology This short communication queried the publicly available Department of Health statistics on COVID-19 related mortality and underlying health conditions in four southern states (Alabama [AL], Georgia [GA], Louisiana [LA] and Mississippi [MS]) with a high proportion of African American residents. Second, unacast COVID-19 toolkit was used to derive a social distancing (SD) grade for any given state, based on three different metrics: (i) percent change in average distance travelled (ii) percent change in non-essential visits and (iii) decrease in human encounters (compared to national baseline). Results Across the four states, on average, as many as 54% of COVID-19 related deaths are in the African American community, although this minority group comprises only 32% of the population cumulatively. This article finds that all four southern states received a social distancing grade of F. COVID-19 have demonstrated that adverse outcomes are higher in individuals with underlying health conditions such as diabetes, cardiovascular diseases, or pre-existing pulmonary compromise. Conclusion Recognizing that there is a great need for African American representation or diversity in the health workforce would be able to better address the health disparities. In addition, the lack of diversity in the healthcare system causes the morbidity and mortality rates to increase in the African American communities because it is not able to address its primary obligations within the African American communities in the southern states during COVID-19 pandemic. These primary obligations are to restore, protect, improve health and to suppress health disparities and inequalities of COVID-19 within in the African American communities.

COVID-19 in African-Americans | 41 | Covid-19 and Inequity: A comparative spatial analysis of New York City and Chicago hot spots | There have been numerous reports that the impact of the ongoing COVID-19 epidemic has disproportionately impacted traditionally vulnerable communities, including well-researched social determinants of health, such as racial and ethnic minorities, migrants, and the economically challenged. The goal of this ecological cross-sectional study is to examine the demographic and economic nature of spatial hot and cold spots of SARS-CoV-2 rates in New York City and Chicago as of April 13, 2020. In both cities, cold spots (clusters of low SARS-CoV-2 rate ZIP code tabulation areas) demonstrated typical protective factors associated with the social determinants of health and the ability to social distance. These neighborhoods tended to be wealthier, have higher educational attainment, higher proportions of non-Hispanic white residents, and more workers in managerial occupations. Hot spots (clusters of high SARS-CoV-2 rate ZIP code tabulation areas) also had similarities, such as lower rates of college graduates and higher proportions of people of color. It also appears to be larger households (more people per household), rather than overall population density, that may to be a more strongly associated with hot spots. Findings suggest important differences between the cities' hot spots as well. They can be generalized by describing the NYC hot spots as working-class and middle-income communities, perhaps indicative of service workers and other occupations (including those classified as "essential services" during the pandemic) that may not require a college degree but pay wages above poverty levels. Chicago's hot spot neighborhoods, on the other hand, are among the city's most vulnerable, low-income neighborhoods with extremely high rates of poverty, unemployment, and non-Hispanic Black residents. | 0xqxledk |
COVID-19 in African-Americans | 41 | Clinical, Behavioral and Social Factors Associated with Racial Disparities in Hospitalized and Ambulatory COVID-19 Patients from an Integrated Health Care System in Georgia | Introduction: Racial and ethnic minorities have shouldered a disproportioned burden of coronavirus disease 2019 (COVID-19) infection to date in the US, but data on the various drivers of these disparities is limited. Objectives: To describe the characteristics and outcomes of COVID-19 patients and explore factors associated with hospitalization risk by race. Methods: Case series of 448 consecutive patients with confirmed COVID-19 seen at Kaiser Permanente Georgia (KPGA), an integrated health care system serving the Atlanta metropolitan area, from March 3 to May 12, 2020. KPGA members with laboratory-confirmed COVID-19. Multivariable analyses for hospitalization risk also included an additional 3489 persons under investigation (PUI) with suspected infection. COVID-19 treatment and outcomes, underlying comorbidities and quality of care management metrics, socio-demographic and other individual and community-level social determinants of health (SDOH) indicators. Results: Of 448 COVID-19 positive members, 68,3% was non-Hispanic Black (n=306), 18% non-Hispanic White (n=81) and 13,7% Other race (n=61). Median age was 54 [IQR 43-63) years. Overall, 224 patients were hospitalized, median age 60 (50-69) years. Black race was a significant factor in the Confirmed + PUI, female and male models (ORs from 1.98 to 2.19). Obesity was associated with higher hospitalization odds in the confirmed, confirmed + PUI, Black and male models (ORs from 1.78 to 2.77). Chronic disease control metrics (diabetes, hypertension, hyperlipidemia) were associated with lower odds of hospitalization ranging from 48% to 35% in the confirmed + PUI and Black models. Self-reported physical inactivity was associated with 50% higher hospitalization odds in the Black and Female models. Residence in the Northeast region of Atlanta was associated with lower hospitalization odds in the Confirmed + PUI, White and female models (ORs from 0.22 to 0.64) Conclusions: We found that non-Hispanic Black KPGA members had a disproportionately higher risk of infection and, after adjusting for covariates, twice the risk of hospitalization compared to other race groups. We found no significant differences in clinical outcomes or mortality across race/ethnicity groups. In addition to age, sex and comorbidity burden, pre-pandemic self-reported exercise, metrics on quality of care and control of underlying cardio-metabolic diseases, and location of residence in Atlanta were significantly associated with hospitalization risk by race groups. Beyond well-known physiologic and clinical factors, individual and community-level social indicators and health behaviors must be considered as interventions designed to reduce COVID-19 disparities and the systemic effects of racism are implemented. | ix2cbs4j |
COVID-19 in African-Americans | 41 | Stay-at-Home Orders, African American Population, Poverty and State-level Covid-19 Infections: Are there associations? | Importance: To cope with the continuing COVID-19 pandemic, state and local health officials need information on the effectiveness of policies aimed at curbing contagion, as well as area-specific socio-demographic characteristics that can portend vulnerability to the disease. Objective: To investigate whether state-imposed stay-at-home orders, African American population in the state, state poverty and other state socio-demographic characteristics, were associated with the state-level incidence of COVID-19 infection. Design, Setting, Participants: State-level, aggregated, publicly available data on positive COVID-19 cases and tests were used. The period considered was March 1st -May 4th. All U.S. states except Washington were included. Outcomes of interest were daily cumulative and daily incremental COVID-19 infection rates. Outcomes were log-transformed. Log-linear regression models with a quadratic time-trend and random intercepts for states were estimated. Covariates included log-transformed test-rates, a binary indicator for stay-at-home, percentage of African American, poverty, percentage elderly, state population and prevalence of selected comorbidities. Binary fixed effects for date each state first started reporting test data were included. Results: Stay-at-home orders were associated with decreases in cumulative ({beta}:-1.23; T-stat: -6.84) and daily ({beta}:-0.46; T-stat: -2.56) infection-rates. Predictive analyses indicated that expected cumulative infection rates would be 3 times higher and expected daily incremental rates about 60% higher in absence of stay-at-home orders. Higher African American population was associated with higher cumulative ({beta}: 0.08; T-stat: 4.01) and daily ({beta}: 0.06; T-stat: 3.50) rates. State poverty rates had mixed results and were not robust to model specifications. There was strong evidence of a quadratic daily trend for cumulative and daily rates. Results were largely robust to alternate specifications. Conclusions: We find evidence that stay-at-home orders, which were widely supported by public-health experts, helped to substantially curb COVID-19 infection-rates. As we move to a phased re-opening, continued precautions advised by public-health experts should be adhered to. Also, a larger African American population is strongly associated with incidence of COVID-19 infection. Policies and resources to help mitigate African American vulnerability to COVID-19 is an urgent public health and social justice issue, especially since the ongoing mass protests against police brutality may further exacerbate COVID-19 contagion in this community. | csujgaae |
COVID-19 in African-Americans | 41 | A case-control and cohort study to determine the relationship between ethnic background and severe COVID-19 | Background. People of minority ethnic background may be disproportionately affected by severe COVID-19 for reasons that are unclear. We sought to examine the relationship between ethnic background and (1) hospital admission for severe COVID-19; (2) in-hospital mortality. Methods. We conducted a case-control study of 872 inner city adult residents admitted to hospital with confirmed COVID-19 (cases) and 3,488 matched controls randomly sampled from a primary healthcare database comprising 344,083 people resident in the same region. To examine in-hospital mortality, we conducted a cohort study of 1827 adults consecutively admitted with COVID-19. Data collected included hospital admission for COVID-19, demographics, comorbidities, in-hospital mortality. The primary exposure variable was self-defined ethnicity. Results. The 872 cases comprised 48.1% Black, 33.7% White, 12.6% Mixed/Other and 5.6% Asian patients. In conditional logistic regression analyses, Black and Mixed/Other ethnicity were associated with higher admission risk than white (OR 3.12 [95% CI 2.63-3.71] and 2.97 [2.30- 3.85] respectively). Adjustment for comorbidities and deprivation modestly attenuated the association (OR 2.28 [1.87-2.79] for Black, 2.66 [2.01-3.52] for Mixed/Other). Asian ethnicity was not associated with higher admission risk (OR 1.20 [0.86-1.66]). In the cohort study of 1827 patients, 455 (28.9%) died over a median (IQR) of 8 (4-16) days. Age and male sex, but not Black (adjusted HR 0.84 [0.63-1.11]) or Mixed/Other ethnicity (adjusted HR 0.69 [0.43-1.10]), were associated with in-hospital mortality. Asian ethnicity was associated with higher in-hospital mortality (adjusted HR 1.54 [0.98-2.41]). Conclusions. Black and Mixed ethnicity are independently associated with greater admission risk with COVID-19 and may be risk factors for development of severe disease. Comorbidities and socioeconomic factors only partly account for this and additional ethnicity-related factors may play a large role. The impact of COVID-19 may be different in Asians. | gadui4r7 |
COVID-19 in African-Americans | 41 | Comorbidities and Disparities in Outcomes of COVID-19 Among African American and White Patients | Initial surveillance data suggests a disproportionately high number of deaths among Black patients with COVID-19. However, high-risk comorbidities are often over-represented in the Black population, and understanding whether the disparity is entirely secondary to them is essential. We performed a retrospective cohort study using real-time analysis of electronic medical records (EMR) of patients from multiple healthcare organizations in the United States. Our results showed that Black patients with COVID-19 have a significantly higher risk of mortality, hospitalization, and invasive mechanical ventilation compared to White patients. The incremental risk of poor outcomes in Blacks persists despite accounting for a higher prevalence of comorbidities. This may point to the disparities in socioeconomic determinants of health affecting Blacks and the need for an improvement in the care of this vulnerable population. | cuo7qdkj |
COVID-19 in African-Americans | 41 | Updated estimates of comorbidities associated with risk for COVID-19 complications based on US data | We updated previous estimates (wwwnc.cdc.gov/eid/article/26/8/20-0679_article) of adults with any underlying condition increasing risk of complications from COVID-19 using recent US hospitalization data instead of mortality data from China. This substitutes obesity for cancer in the definition and increased the percentage of adults reporting more than 1 condition to 56.0% (95% CI 55.7-56.4). When controlled for all measures listed, factors increasing odds of reporting any of the underlying conditions include being male, older, African American, American Indian, household income <$25,000, < high school education, underinsurance, living in the South or Midwest (vs. West), plus the risk factors of ever smoking, sedentary lifestyle, and inadequate fruit and vegetable consumption. Population-attributable risk for the listed risk factors was 13.0%, 12.6%, and 15.0% respectively. Results have potential implications for policies based on risk-stratification of the population and for improvement of risk status through lifestyle change. National support for a health promotion campaign would be timely. | 1dkkwt7h |
COVID-19 in African-Americans | 41 | Prevalence of regular physical activity among adults--United States, 2001 and 2005. | Regular physical activity is associated with decreased risk for obesity, heart disease, hypertension, diabetes, certain cancers, and premature mortality. CDC and the American College of Sports Medicine recommend that adults engage in at least 30 minutes of moderate physical activity on most days and preferably on all days. Healthy People 2010 objectives include increasing the proportion of adults who engage regularly in moderate or vigorous activity to at least 50% (objective 22-2). In addition, reducing racial and ethnic health disparities, including disparities in physical activity, is an overarching national goal. To examine changes in the prevalence of regular, leisure-time, physical activity from 2001 to 2005, CDC analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS). This report summarizes the results of that analysis, which indicated that, from 2001 to 2005, the prevalence of regular physical activity increased 8.6% among women overall (from 43.0% to 46.7%) and 3.5% among men (from 48.0% to 49.7%). In addition, the prevalence of regular physical activity increased 15.0% (from 31.4% to 36.1%) among non-Hispanic black women and 12.4% (from 40.3% to 45.3%) among non-Hispanic black men, slightly narrowing previous racial disparities when compared with increases of 7.8% (from 46.0% to 49.6%) for white women and 3.4% (from 50.6% to 52.3%) for white men, respectively. CDC, state and local public health agencies, and other public health partners should continue to implement evidence-based, culturally appropriate initiatives to further increase physical-activity levels among all adults, with special focus on eliminating racial/ethnic disparities. | 26f514ay |
COVID-19 in African-Americans | 41 | Disparities in Coronavirus 2019 Reported Incidence, Knowledge, and Behavior Among US Adults | Importance: Data from the coronavirus disease 2019 (COVID-19) pandemic in the US show large differences in hospitalizations and mortality across race and geography. However, there are limited data on health information, beliefs, and behaviors that might indicate different exposure to risk. Objective: To determine the association of sociodemographic characteristics with reported incidence, knowledge, and behavior regarding COVID-19 among US adults. Design, Setting, and Participants: A US national survey study was conducted from March 29 to April 13, 2020, to measure differences in knowledge, beliefs, and behavior about COVID-19. The survey oversampled COVID-19 hotspot areas. The survey was conducted electronically. The criteria for inclusion were age 18 years or older and residence in the US. Data analysis was performed in April 2020. Main Outcomes and Measures: The main outcomes were incidence, knowledge, and behaviors related to COVID-19 as measured by survey response. Results: The survey included 5198 individuals (mean [SD] age, 48 [18] years; 2336 men [45%]; 3759 white [72%], 830 [16%] African American, and 609 [12%] Hispanic). The largest differences in COVID-19-related knowledge and behaviors were associated with race/ethnicity, sex, and age, with African American participants, men, and people younger than 55 years showing less knowledge than other groups. African American respondents were 3.5 percentage points (95% CI, 1.5 to 5.5 percentage points; P = .001) more likely than white respondents to report being infected with COVID-19, as were men compared with women (3.2 percentage points; 95% CI, 2.0 to 4.4 percentage points; P < .001). Knowing someone who tested positive for COVID-19 was more common among African American respondents (7.2 percentage points; 95% CI, 3.4 to 10.9 percentage points; P < .001), people younger than 30 years (11.6 percentage points; 95% CI, 7.5 to 15.7 percentage points; P < .001), and people with higher incomes (coefficient on earning ≥$100â¯000, 12.3 percentage points; 95% CI, 8.7 to 15.8 percentage points; P < .001). Knowledge of potential fomite spread was lower among African American respondents (-9.4 percentage points; 95% CI, -13.1 to -5.7 percentage points; P < .001), Hispanic respondents (-4.8 percentage points; 95% CI, -8.9 to -0.77 percentage points; P = .02), and people younger than 30 years (-10.3 percentage points; 95% CI, -14.1 to -6.5 percentage points; P < .001). Similar gaps were found with respect to knowledge of COVID-19 symptoms and preventive behaviors. Conclusions and Relevance: In this survey study of US adults, there were gaps in reported incidence of COVID-19 and knowledge regarding its spread and symptoms and social distancing behavior. More effort is needed to increase accurate information and encourage appropriate behaviors among minority communities, men, and younger people. | hhaq25w8 |
COVID-19 in African-Americans | 41 | For us, COVID-19 is personal | We are colleagues and friends working together in busy emergency departments in Washington DC.

COVID-19 in African-Americans | 41 | COVID-19 and the Widening Gap in Health Inequity | The coronavirus disease 2019 (COVID-19) pandemic has brought to light significant health inequities that have existed in our society for decades. Blacks, Hispanics, Native Americans, and immigrants are the populations most likely to experience disparities related to burden of disease, health care, and health outcomes. Increasingly, national and state statistics on COVID-19 report disproportionately higher mortality rates in blacks. There has never been a more pressing time for us to enact progressive and far-reaching changes in social, economic, and political policies that will shape programs aimed at improving the health of all people living in the United States. | 3omm8wkv |

COVID-19 in African-Americans | 41 | Coronavirus disease 19 in minority populations of Newark, New Jersey | BACKGROUND: The purpose of this study is to report the clinical features and outcomes of Black/African American (AA) and Latino Hispanic patients with Coronavirus disease 2019 (COVID-19) hospitalized in an inter-city hospital in the state of New Jersey. METHODS: This is a retrospective cohort study of AA and Latino Hispanic patients with COVID-19 admitted to a 665-bed quaternary care, teaching hospital located in Newark, New Jersey. The study included patients who had completed hospitalization between March 10, 2020, and April 10, 2020. We reviewed demographics, socioeconomic variables and incidence of in-hospital mortality and morbidity. Logistic regression was used to identify predictor of in-hospital death. RESULTS: Out of 416 patients, 251 (60%) had completed hospitalization as of April 10, 2020. The incidence of In-hospital mortality was 38.6% (n = 97). Most common symptoms at initial presentation were dyspnea 39% (n = 162) followed by cough 38%(n = 156) and fever 34% (n = 143). Patients were in the highest quartile for population's density, number of housing units and disproportionately fell into the lowest median income quartile for the state of New Jersey. The incidence of septic shock, acute kidney injury (AKI) requiring hemodialysis and admission to an intensive care unit (ICU) was 24% (n = 59), 21% (n = 52), 33% (n = 82) respectively. Independent predictors of in-hospital mortality were older age, lower serum Hemoglobin < 10 mg/dl, elevated serum Ferritin and Creatinine phosphokinase levels > 1200 U/L and > 1000 U/L. CONCLUSIONS: Findings from an inter-city hospital's experience with COVID-19 among underserved minority populations showed that, more than one of every three patients were at risk for in-hospital death or morbidity. Older age and elevated inflammatory markers at presentation were associated with in-hospital death. | g7cqx652 |

COVID-19 in African-Americans | 41 | Policy Recommendations to Address High Risk of COVID-19 Among Immigrants | The health and economic consequences of COVID-19 will be devastatingly widespread, but the populations that will suffer most are those who have experienced longstanding health disparities. For example, emerging evidence strongly suggests that incidence and case fatality rates are higher among Blacks than Whites.1 Immigrants are among the groups most likely to experience disproportionate effects from COVID-19. Unlike race/ethnicity, however, nativity and citizenship status are not included on the Centers for Disease Control and Prevention's (CDC's) coronavirus case report form,2 so data regarding testing and spread across immigrant groups are likely to remain scarce. Information from other health and social surveys-including data that I present in Table 1-suggest that noncitizens experience barriers to physical distancing that will place them at high risk of contracting COVID-19 and have high levels of disadvantage that leave them vulnerable to its economic effects. I recommend three policy changes to address the high health and economic risk among noncitizens, goals that are in the best interest of public health and the broader economy. (Am J Public Health.

COVID-19 in African-Americans | 41 | Historical Insights on Coronavirus Disease 2019 (COVID-19), the 1918 Influenza Pandemic, and Racial Disparities: Illuminating a Path Forward | The coronavirus disease 2019 (COVID-19) pandemic is exacting a disproportionate toll on ethnic minority communities and magnifying existing disparities in health care access and treatment. To understand this crisis, physicians and public health researchers have searched history for insights, especially from a great outbreak approximately a century ago: the 1918 influenza pandemic. However, of the accounts examining the 1918 influenza pandemic and COVID-19, only a notable few discuss race. Yet, a rich, broader scholarship on race and epidemic disease as a "sampling device for social analysis" exists. This commentary examines the historical arc of the 1918 influenza pandemic, focusing on black Americans and showing the complex and sometimes surprising ways it operated, triggering particular responses both within a minority community and in wider racial, sociopolitical, and public health structures. This analysis reveals that critical structural inequities and health care gaps have historically contributed to and continue to compound disparate health outcomes among communities of color. Shifting from this context to the present, this article frames a discussion of racial health disparities through a resilience approach rather than a deficit approach and offers a blueprint for approaching the COVID-19 crisis and its afterlives through the lens of health equity. | 6l0pqp6l |
COVID-19 in African-Americans | 41 | Racial Capitalism within Public Health: How Occupational Settings Drive COVID-19 Disparities | Epidemiology of the U.S. COVID-19 outbreak focuses on individuals' biology and behaviors, despite centrality of occupational environments in the viral spread. This demonstrates collusion between epidemiology and racial capitalism because it obscures structural influences, absolving industries of responsibility for worker safety. In an empirical example, we analyze economic implications of race-based metrics widely used in occupational epidemiology. In the U.S., White adults have better average lung function and worse hearing than Black adults. Both impaired lung function and hearing are criteria for Worker's compensation, which is ultimately paid by industry. Compensation for respiratory injury is determined using a race-specific algorithm. For hearing, there is no race adjustment. Selective use of race-specific algorithms for workers' compensation reduces industries' liability for worker health, illustrating racial capitalism operating within public health. Widespread and unexamined belief in inherent physiological inferiority of Black Americans perpetuates systems that limit industry payouts for workplace injuries. We see a parallel in the epidemiology of COVID-19 disparities. We tell stories of industries implicated in the outbreak and review how they exemplify racial capitalism. We call on public health professionals to: critically evaluate who is served and neglected by data analysis; and center structural determinants of health in etiological evaluation. | betyinap |

COVID-19 in African-Americans | 41 | Black-White Risk Differentials in COVID-19 (SARS-COV2) Transmission, Mortality and Case Fatality in the United States: Translational Epidemiologic Perspective and Challenges | BACKGROUND: Social and health inequities predispose vulnerable populations to adverse morbidity and mortality outcomes of epidemics and pandemics. While racial disparities in cumulative incidence (CmI) and mortality from the influenza pandemics of 1918 and 2009 implicated Blacks with survival disadvantage relative to Whites in the United States, COVID-19 currently indicates comparable disparities. We aimed to: (a) assess COVID-19 CmI by race, (b) determine the Black-White case fatality (CF) and risk differentials, and (c) apply explanatory model for mortality risk differentials. METHODS: COVID-19 data on confirmed cases and deaths by selective states health departments were assessed using a cross-sectional ecologic design. Chi-square was used for CF independence, while binomial regression model for the Black-White risk differentials. RESULTS: The COVID-19 mortality CmI indicated Blacks/AA with 34% of the total mortality in the United States, albeit their 13% population size. The COVID-19 CF was higher among Blacks/AA relative to Whites; Maryland, (2.7% vs. 2.5%), Wisconsin (7.4% vs. 4.8%), Illinois (4.8% vs. 4.2%), Chicago (5.9% vs. 3.2%), Detroit (Michigan), 7.2% and St. John the Baptist Parish (Louisiana), 7.9%. Blacks/AA compared to Whites in Michigan were 15% more likely to die, CmI risk ratio (CmIRR) = 1.15, 95% CI, 1.01-1.32. Blacks/AA relative to Whites in Illinois were 13% more likely to die, CmIRR = 1.13, 95% CI, 0.93-1.39, while Blacks/AA compared to Whites in Wisconsin were 51% more likely to die, CmIRR = 1.51, 95% CI, 1.10-2.10. In Chicago, Blacks/AA were more than twice as likely to die, CmIRR = 2.24, 95% CI, 1.36-3.88. CONCLUSION: Substantial racial/ethnic disparities are observed in COVID-19 CF and mortality with Blacks/AA disproportionately affected across the United States. | 9cy1jrw9 |
COVID-19 in African-Americans | 41 | A culturally specific mental health and spirituality approach for African Americans facing the COVID-19 pandemic | A series of 15-min videos were produced to provide resources to pastors in African-American communities to aid them in conveying accurate public and mental health information about COVID-19. Video presenters included trusted experts in public and mental health and pastors with considerable experience responding to the needs of the African-American community during the COVID-19 pandemic. Four culturally specific core themes to consider when providing care to African Americans who are at increased risk during the pandemic were identified: ritual disruption, negative reactions for not following public health guidelines, trauma, and culture and trust.

COVID-19 in African-Americans | 41 | Racial and Ethnic Digital Divides in Posting COVID-19 Content on Social Media Among US Adults: Secondary Survey Analysis | BACKGROUND: Public health surveillance experts are leveraging user-generated content on social media to track the spread and effects of COVID-19. However, racial and ethnic digital divides, which are disparities among people who have internet access and post on social media, can bias inferences. This bias is particularly problematic in the context of the COVID-19 pandemic because due to structural inequalities, members of racial and ethnic minority groups are disproportionately vulnerable to contracting the virus and to the deleterious economic and social effects from mitigation efforts. Further, important demographic intersections with race and ethnicity, such as gender and age, are rarely investigated in work characterizing social media users; however, they reflect additional axes of inequality shaping differential exposure to COVID-19 and its effects. OBJECTIVE: The aim of this study was to characterize how the race and ethnicity of US adults are associated with their odds of posting COVID-19 content on social media and how gender and age modify these odds. METHODS: We performed a secondary analysis of a survey conducted by the Pew Research Center from March 19 to 24, 2020, using a national probability sample (N=10,510). Respondents were recruited from an online panel, where panelists without an internet-enabled device were given one to keep at no cost. The binary dependent variable was responses to an item asking whether respondents "used social media to share or post information about the coronavirus." We used survey-weighted logistic regressions to estimate the odds of responding in the affirmative based on the race and ethnicity of respondents (white, black, Latino, other race/ethnicity), adjusted for covariates measuring sociodemographic background and COVID-19 experiences. We examined how gender (female, male) and age (18 to 30 years, 31 to 50 years, 51 to 64 years, and 65 years and older) intersected with race and ethnicity by estimating interactions. RESULTS: Respondents who identified as black (odds ratio [OR] 1.29, 95% CI 1.02-1.64; P=.03), Latino (OR 1.66, 95% CI 1.36-2.04; P<.001), or other races/ethnicities (OR 1.33, 95% CI 1.02-1.72; P=.03) had higher odds than respondents who identified as white of reporting that they posted COVID-19 content on social media. Women had higher odds of posting than men regardless of race and ethnicity (OR 1.58, 95% CI 1.39-1.80; P<.001). Among men, respondents who identified as black, Latino, or members of other races/ethnicities were significantly more likely to post than respondents who identified as white. Older adults (65 years or older) had significantly lower odds (OR 0.73, 95% CI 0.57-0.94; P=.01) of posting compared to younger adults (18-29 years), particularly among those identifying as other races/ethnicities. Latino respondents were the most likely to report posting across all age groups. CONCLUSIONS: In the United States, members of racial and ethnic minority groups are most likely to contribute to COVID-19 content on social media, particularly among groups traditionally less likely to use social media (older adults and men). The next step is to ensure that data collection procedures capture this diversity by encompassing a breadth of search criteria and social media platforms. | d6hfczkq |

COVID-19 in African-Americans | 41 | Differential occupational risk for COVID-19 and other infection exposure according to race and ethnicity | BACKGROUND: There are racial and ethnic disparities in the risk of contracting COVID-19. This study sought to assess how occupational segregation according to race and ethnicity may contribute to the risk of COVID-19. METHODS: Data about employment in 2019 by industry and occupation and race and ethnicity were obtained from the Bureau of Labor Statistics Current Population Survey. This data was combined with information about industries according to whether they were likely or possibly essential during the COVID-19 pandemic and the frequency of exposure to infections and close proximity to others by occupation. The percentage of workers employed in essential industries and occupations with a high risk of infection and close proximity to others by race and ethnicity was calculated. RESULTS: People of color were more likely to be employed in essential industries and in occupations with more exposure to infections and close proximity to others. Black workers in particular faced an elevated risk for all of these factors. CONCLUSION: Occupational segregation into high-risk industries and occupations likely contributes to differential risk with respect to COVID-19. Providing adequate projection to workers may help to reduce these disparities. | 8ffds4yc |

COVID-19 in African-Americans | 41 | Social and psychological consequences of the COVID-19 pandemic in African-American communities: Lessons from Michigan | The mental health consequences of the COVID-19 pandemic are particularly relevant in African-American communities because African-Americans have been disproportionately impacted by the disease, yet they are traditionally less engaged in mental health treatment compared with other racial groups. Using the state of Michigan as an example, we describe the social and psychological consequences of the pandemic on African-American communities in the United States, highlighting community members' concerns about contracting the disease, fears of racial bias in testing and treatment, experiences of sustained grief and loss, and retraumatization of already-traumatized communities. Furthermore, we describe the multilevel, community-wide approaches that have been used thus far to mitigate adverse mental health outcomes within our local African-American communities.

Vitamin D and COVID-19 | 42 | Inadequacy of Immune Health Nutrients: Intakes in US Adults, the 2005–2016 NHANES | A well-functioning immune system is essential for human health and well-being. Micronutrients such as vitamins A, C, D, E, and zinc have several functions throughout the immune system, yet inadequate nutrient intakes are pervasive in the US population. A large body of research shows that nutrient inadequacies can impair immune function and weaken the immune response. Here, we present a new analysis of micronutrient usual intake estimates based on nationally representative data in 26,282 adults (>19 years) from the 2005–2016 National Health and Nutrition Examination Surveys (NHANES). Overall, the prevalence of inadequacy (% of population below estimated average requirement [EAR]) in four out of five key immune nutrients is substantial. Specifically, 45% of the U.S. population had a prevalence of inadequacy for vitamin A, 46% for vitamin C, 95% for vitamin D, 84% for vitamin E, and 15% for zinc. Dietary supplements can help address nutrient inadequacy for these immune-support nutrients, demonstrated by a lower prevalence of individuals below the EAR. Given the long-term presence and widening of nutrient gaps in the U.S.—specifically in critical nutrients that support immune health—public health measures should adopt guidelines to ensure an adequate intake of these micronutrients. Future research is needed to better understand the interactions and complexities of multiple nutrient shortfalls on immune health and assess and identify optimal levels of intake in at-risk populations. | bd10ce5d |

Vitamin D and COVID-19 | 42 | The link between Vitamin D and Covid-19: distinguishing facts from fiction. | Vitamin D is produced in the skin under the influence of UVB-light from the sun or obtained via the diet by eating fatty fish, enriched dairy products or supplements. Vitamin D is known to support a healthy bone and severe deficiency may lead to osteomalacia or the rickets, which still occur in poor areas of the world. In addition, vitamin D support key functions in many organs, including the brain, muscle and the immune systems (Holick, 2007). In fact, the vitamin D receptor (VDR) is expressed in most cell types and may activate somewhere between 200-500 genes, many related to the immune system. | n2ku9n0d |
Vitamin D and COVID-19 | 42 | Nutrients in prevention, treatment, and management of viral infections; special focus on Coronavirus. | BACKGROUND The coronavirus disease 2019 (COVID-19) is a pandemic caused by coronavirus with mild to severe respiratory symptoms. This paper aimed to investigate the effect of nutrients on the immune system and their possible roles in the prevention, treatment, and management of COVID-19 in adults. METHODS This Systematic review was designed based on the guideline of the Preferred Reporting for Systematic Reviews (PRISMA). The articles that focussed on nutrition, immune system, viral infection, and coronaviruses were collected by searching databases for both published papers and accepted manuscripts from 1990 to 2020. Irrelevant papers and articles without English abstract were excluded from the review process. RESULTS Some nutrients are actively involved in the proper functioning and strengthening of the human immune system against viral infections including dietary protein, omega-3 fatty acids, vitamin A, vitamin D, vitamin E, vitamin B1, vitamin B6, vitamin B12, vitamin C, iron, zinc, and selenium. Few studies were done on the effect of dietary components on prevention of COVID-19, but supplementation with these nutrients may be effective in improving the health status of patients with viral infections. CONCLUSION Following a balanced diet and supplementation with proper nutrients may play a vital role in prevention, treatment, and management of COVID-19. However, further clinical trials are needed to confirm these findings and presenting the strong recommendations against this pandemic. | 478wbtfb |
Vitamin D and COVID-19 | 42 | Greater risk of severe COVID-19 in Black, Asian and Minority Ethnic populations is not explained by cardiometabolic, socioeconomic or behavioural factors, or by 25(OH)-vitamin D status: study of 1326 cases from the UK Biobank. | BACKGROUND We examined whether the greater severity of coronavirus disease 2019 (COVID-19) amongst men and Black, Asian and Minority Ethnic (BAME) individuals is explained by cardiometabolic, socio-economic or behavioural factors. METHODS We studied 4510 UK Biobank participants tested for COVID-19 (positive, n = 1326). Multivariate logistic regression models including age, sex and ethnicity were used to test whether addition of (1) cardiometabolic factors [diabetes, hypertension, high cholesterol, prior myocardial infarction, smoking and body mass index (BMI)]; (2) 25(OH)-vitamin D; (3) poor diet; (4) Townsend deprivation score; (5) housing (home type, overcrowding) or (6) behavioural factors (sociability, risk taking) attenuated sex/ethnicity associations with COVID-19 status. RESULTS There was over-representation of men and BAME ethnicities in the COVID-19 positive group. BAME individuals had, on average, poorer cardiometabolic profile, lower 25(OH)-vitamin D, greater material deprivation, and were more likely to live in larger households and in flats/apartments. Male sex, BAME ethnicity, higher BMI, higher Townsend deprivation score and household overcrowding were independently associated with significantly greater odds of COVID-19. The pattern of association was consistent for men and women; cardiometabolic, socio-demographic and behavioural factors did not attenuate sex/ethnicity associations. CONCLUSIONS In this study, sex and ethnicity differential pattern of COVID-19 was not adequately explained by variations in cardiometabolic factors, 25(OH)-vitamin D levels or socio-economic factors. Factors which underlie ethnic differences in COVID-19 may not be easily captured, and so investigation of alternative biological and genetic susceptibilities as well as more comprehensive assessment of the complex economic, social and behavioural differences should be prioritised. | 85tgrqab |
Vitamin D and COVID-19 | 42 | [Vitamin D and coronavirus: a new field of use?] | Given the succession of communications in scientific and popular circuits, tending to take for granted a role for vitamin D in the control of the coronavirus pandemic, the authors conducted an analysis of the literature currently available in order to recognize what is supported by opinions personal and what evidence of effectiveness. At the end of the bibliographic survey there is the current absence of evidence of efficacy in favor of vitamin D in the treatment of coronavirus infection in its various expressions. The diffusion of personal opinions as if they were evidence can be a disturbing factor for adequate assistance and for correct research. | 34f1ie66 |

Vitamin D and COVID-19 | 42 | Vitamin A and micronutrient deficiencies post-bariatric surgery: aetiology, complications and management in a complex multiparous pregnancy. | Adequate vitamin A is essential for healthy pregnancy, but high levels may be teratogenic. We present a patient who underwent bariatric surgery, prior to child bearing, and suffered maternal and foetal complications during eleven pregnancies, possibly associated with vitamin A deficiency, amongst multiple micronutrient deficiencies and risk factors including smoking and obesity. Maternal complications included visual disturbance, night blindness and recurrent infections. Recurrent foetal pulmonary hypoplasia and microphthalmia led to foetal and neonatal loss, not previously described in the medical literature. Current guidance on vitamin A deficiency in pregnancy is focused on developing countries where aetiology of vitamin A deficiency is different to that of women in developed countries. We describe nutritional management of the micronutritient deficiencies, focusing on vitamin A, during her last pregnancy. The need for specific antenatal nutritional guidance for pregnant women post-bariatric surgery is becoming more urgent as more mothers and offspring will be affected. | 5den4c7m |
Vitamin D and COVID-19 | 42 | Can Composite Nutritional Supplement Based on the Current Guidelines Prevent Vitamin and Mineral Deficiency After Weight Loss Surgery? | BACKGROUND Nutritional deficiencies occur after weight loss surgery. Despite knowledge of nutritional risk, there is little uniformity of postoperative vitamin and mineral supplementation. The objective of this study was to evaluate a composite supplement based on the clinical practice guidelines proposed in 2008 regarding vitamin and mineral supplementation after Roux-en-Y gastric bypass. The composite included iron (Fe) and calcium as well. METHODS A retrospective chart review of 309 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) was evaluated for the development of deficiencies in iron and vitamins A, B1, B12, and D. Patients were instructed to take a custom vitamin and mineral supplement that was based on society-approved guidelines. The clinical practice guidelines were modified to include 1600 international units (IU) of vitamin D3 instead of the recommended 800 IU. RESULTS The compliant patients' deficiency rates were significantly lower than those of the noncompliant patients for iron (p = 0.001), vitamin A (p = 0.01), vitamin B12 (p ≈ 0.02), and vitamin D (p < 0.0001). Women's menstrual status did not significantly influence the development of iron deficiency. CONCLUSIONS Use of a composite based on guidelines proposed by the AACE, TOS, and the ASMBS appears to be effective for preventing iron and vitamins A, B1, B12, and D deficiencies in the LRYGB patients during the first postoperative year. Separation of calcium and Fe does not need to be mandatory. Even with simplification, compliance is far from universal. | 3q2jju2u |

Vitamin D and COVID-19 | 42 | Combating COVID-19 and Building Immune Resilience: A Potential Role for Magnesium Nutrition? | BACKGROUND In December 2019, the viral pandemic of respiratory illness caused by COVID-19 began sweeping its way across the globe. Several aspects of this infectious disease mimic metabolic events shown to occur during latent subclinical magnesium deficiency. Hypomagnesemia is a relatively common clinical occurrence that often goes unrecognized since magnesium levels are rarely monitored in the clinical setting. Magnesium is the second most abundant intracellular cation after potassium. It is involved in >600 enzymatic reactions in the body, including those contributing to the exaggerated immune and inflammatory responses exhibited by COVID-19 patients. METHODS A summary of experimental findings and knowledge of the biochemical role magnesium may play in the pathogenesis of COVID-19 is presented in this perspective. The National Academy of Medicine's Standards for Systematic Reviews were independently employed to identify clinical and prospective cohort studies assessing the relationship of magnesium with interleukin-6, a prominent drug target for treating COVID-19. RESULTS Clinical recommendations are given for prevention and treatment of COVID-19. Constant monitoring of ionized magnesium status with subsequent repletion, when appropriate, may be an effective strategy to influence disease contraction and progression. The peer-reviewed literature supports that several aspects of magnesium nutrition warrant clinical consideration. Mechanisms include its "calcium-channel blocking" effects that lead to downstream suppression of nuclear factor-Kβ, interleukin-6, c-reactive protein, and other related endocrine disrupters; its role in regulating renal potassium loss; and its ability to activate and enhance the functionality of vitamin D, among others. CONCLUSION As the world awaits an effective vaccine, nutrition plays an important and safe role in helping mitigate patient morbidity and mortality. Our group is working with the Academy of Nutrition and Dietetics to collect patient-level data from intensive care units across the United States to better understand nutrition care practices that lead to better outcomes. | l76bqsn0 |
Vitamin D and COVID-19 | 42 | Reviews of Science for Science Librarians: Vitamins and Trace Elements that May Be Preventive or Ameliorating in This Age of Contagion | Prompted by COVID-19, many laypersons now seek information on nutritional support to ward off or help shorten the effects of serious infectious diseases, and are attracted to practices and substances that lack a serious scientific basis. This paper scanned peer-reviewed medical literature to prove a concept: That diets or supplements rich in some vitamins or minerals may indeed be important in managing threats to health caused by a variety of infectious diseases in the past and compares these findings to the current recommendations of the Academy of Nutrition and Dietetics and to research by Zhang and Liu, two China-based pioneers in countering COVID-19. Vitamins A, D, and zinc, are common to both groups and are well supported in the literature. Vitamin C is also a common denominator but has a mixed record of efficacy in dealing with prior infectious outbreaks. Iron has support and do some other vitamins and trace elements. Health science librarians should emphasize that while experts can disagree on particular micronutrients they tend to agree that decisions on protective or curative supplements or diets or should have some basis in fact. | 5uo2bxiv |
Vitamin D and COVID-19 | 42 | Spurious Correlation? A review of the relationship between Vitamin D and Covid-19 infection and mortality | The study reviews the evidence presented in a recent study linking vitamin D levels and Covid-19 infection and mortality. It was argued that correlation alone may not be useful in establishing a relationship between vitamin D levels and Covid-19 infections and mortality. Appropriate controls need to be included for improved understanding of the relationship. We proposed life expectancy as a potential control. Including this control in a regression model, we find that vitamin D levels are not a statistically significant predictor of Covid-19 infections or mortality. Life expectancy, on the other hand, was found to be statistically significant predictor of infections and mortality at country level. | hevwcofh |
Vitamin D and COVID-19 | 42 | Short Communication: Vitamin D and COVID-19 infection and mortality in UK Biobank | Purpose Vitamin D has been proposed as a potential causal factor in COVID-19 risk. We aimed to establish whether blood 25-hydroxyvitamin D (25(OH)D) concentration was associated with COVID-19 mortality, and inpatient confirmed COVID-19 infection, in UK Biobank participants. Methods UK Biobank recruited 502,624 participants aged 37-73 years between 2006 and 2010. Baseline exposure data, including 25(OH)D concentration, were linked to COVID-19 mortality. Univariable and multivariable Cox proportional hazards regression analyses were performed for the association between 25(OH)D and COVID-19 death, and poisson regression analyses for the association between 25(OH)D and severe COVID-19 infection. Results Complete data were available for 341,484 UK Biobank participants, of which 656 had inpatient confirmed COVID-19 infection and 203 died of COVID-19 infection. Vitamin D was associated with severe COVID-19 infection and mortality univariably (mortality HR=0.99; 95% CI 0.98-0.998; p=0.016), but not after adjustment for confounders (mortality HR=0.998; 95% CI=0.99-1.01; p=0.696). Conclusions Our findings do not support a potential link between vitamin D concentrations and risk of severe COVID-19 infection and mortality. Recommendations for vitamin D supplementation to lessen COVID-19 risks may provide false reassurance. | npk92gra |
Vitamin D and COVID-19 | 42 | Vitamin D and Inflammation: Potential Implications for Severity of Covid-19. | Background Recent research has indicated that vitamin D may have immune supporting properties through modulation of both the adaptive and innate immune system through cytokines and regulation of cell signalling pathways. We hypothesize that vitamin D status may influence the severity of responses to Covid-19 and that the prevalence of vitamin D deficiency in Europe will be closely aligned to Covid-19 mortality. Methods We conducted a literature search on PubMed (no language restriction) of vitamin D status (for older adults) in countries/areas of Europe affected by Covid-19 infection. Countries were selected by severity of infection (high and low) and were limited to national surveys or where not available, to geographic areas within the country affected by infection. Covid-19 infection and mortality data was gathered from the World Health Organisation. Results Counter-intuitively, lower latitude and typically 'sunny' countries such as Spain and Italy (particularly Northern Italy), had low mean concentrations of 25(OH)D and high rates of vitamin D deficiency. These countries have also been experiencing the highest infection and death rates in Europe. The northern latitude countries (Norway, Finland, Sweden) which receive less UVB sunlight than Southern Europe, actually had much higher mean 25(OH)D concentrations, low levels of deficiency and for Norway and Finland, lower infection and death rates. The correlation between 25(OH)D concentration and mortality rate reached conventional significance (P=0.046) by Spearman's Rank Correlation. Conclusions Optimising vitamin D status to recommendations by national and international public health agencies will certainly have benefits for bone health and potential benefits for Covid-19. There is a strong plausible biological hypothesis and evolving epidemiological data supporting a role for vitamin D in Covid-19. | jvyr7pq4 |
