title: Digital Translucence: Adapting Telemedicine Delivery Post-COVID-19

text: In nearly 1 month, with a rapidly expanding corona virus disease 2019 (COVID-19), telemedicine has been transformed into an essential service for delivering routine clinical care. This transformation occurred as a crisis management response-driven by the need to provide care for patients with physical distancing measures in place. However, the current rapid adoption of telemedicine presents a transitional state between one that existed before the pandemic and one that could potentially be better aligned with the delivery of a personalized model of care. Using the conceptual framework of digital translucence-situating virtual encounters with more nuanced information regarding patients-we describe the role of integrated remote monitoring and virtual care tools aligned with the patient's electronic health record for adapting telemedicine delivery post-COVID-19.

title: Groupe de travail SFBC « Marqueurs biochimiques de COVID-19 ¼./ SFBC working group "Biochemical markers of COVID-19"

text: The SARS-CoV-2 virus is responsible for an epidemic disease called COVID-19, which was initially evidenced in Wuhan, China, and spread very rapidly in China and around the world. In France, the first isolated case seems now to be reported in December 2019, stage 3 of the COVID-19 epidemic was triggered on March 14th, the start of the planned containment exit from May 11th. Healthcare services have faced a large influx of patients who may be beyond their capacity to receive and care, particularly in the Large-East and Ile-de-France regions. Some patients show an evolution of the disease never observed before with other coronaviruses and develop in a few days a very important inflammatory reaction, which can lead to death of patients. A working group of the French Society of Clinical Biology (SFBC) was set up with the objective of providing updated information on the current status of the biological prescriptions (focusing on biochemistry ones) and their evolution during the epidemic, and of analyzing the biological parameters associated with comorbidities and patient evolution in order to link biological results with medical events. The expanded working group covers all sectors of medical biology in France and extends to the French-speaking world: hospital sectors (CHU and CH, Army Training Hospitals) and the private sector opening a field of view on the biological situation in establishments for dependent elderly, social establishments and clinical medical institutions. The purpose of this article is the presentation of this working group and its immediate and future actions.

title: COVID-19: Unanswered questions on immune response and pathogenesis

text: The novel coronavirus disease 2019 has rapidly increased in pandemic scale since it first appeared in Wuhan, China, in December 2019. In these troubled days the scientific community is asking for rapid replies to prevent and combat the emergency. It is generally accepted that only achieving a better understanding of the interactions between the virus and the host immune response and of the pathogenesis of infection is crucial to identify valid therapeutic tools to control virus entry, replication, and spread as well as to impair its lethal effects. On the basis of recent research progress of severe acute respiratory syndrome coronavirus 2 and the results on previous coronaviruses, in this contribution we underscore some of the main unsolved problems, mostly focusing on pathogenetic aspects and host immunity to the virus. On this basis, we also touch important aspects regarding the immune response in asymptomatic subjects, the immune evasion of severe acute respiratory syndrome coronavirus 2 in severe patients, and differences in disease severity by age and sex.


title: Respiratory Distress in Postanesthesia Care Unit: First Presentation of Coronavirus Disease 2019 in a 17-Year-Old Girl: A Case Report

text: A 17-year-old healthy girl underwent an uneventful esthetic septorhinoplasty. She was easily extubated and transferred to the postanesthesia care unit (PACU) with oxygen saturation (SpO2) of 96%. About 30 minutes after arrival in the PACU, she developed dyspnea with SpO2 of 84% and promptly received oxygen with bilevel positive airway pressure in conjunction with low-dose corticosteroid. The subsequent chest computed tomography (CT) revealed bilateral patchy infiltrates similar to the radiologic findings of Coronavirus Disease 2019 (COVID-19). Finally, a reverse transcriptase polymerase chain reaction (RT-PCR) of a pharyngeal specimen confirmed the diagnosis of COVID-19.

title: Is Hypertension a Real Risk Factor for Poor Prognosis in the COVID-19 Pandemic?

text: PURPOSE OF REVIEW: There is increasing evidence indicating an association between several risk factors and worse prognosis in patients with coronavirus disease 2019 (COVID-19), including older age, hypertension, heart failure, diabetes, and pulmonary disease. Hypertension is of particular interest because it is common in adults and there are concerns related to the use of renin-angiotensin system (RAS) inhibitors in patients with hypertension infected with COVID-19. Levels of angiotensin-converting enzyme 2 (ACE2), a protein that facilitates entry of coronavirus into cells, may increase in patients using RAS inhibitors. Thus, chronic use of RAS inhibition could potentially lead to a more severe and fatal form of COVID-19. In this review, we provide a critical review to the following questions: (1) Does hypertension influence immunity or ACE2 expression favoring viral infections? (2) Are the risks of complications in hypertension mediated by its treatment? (3) Is aging a major factor associated with worse prognosis in patients with COVID-19 and hypertension? RECENT FINDINGS: Despite the potential involvement of immune responses in the pathogenesis of hypertension, there is no evidence supporting that hypothesis that hypertension or RAS inhibitors contributes to unfavorable outcomes in viral infections. Future investigations adopting a strict protocol for confirming hypertension status as well as assessing associated comorbidities that may influence outcomes are necessary. From the therapeutic perspective, recombinant ACE2 may serve as a potential therapy, but relevant studies in humans are lacking. Definitive evidence regarding the use of RAS inhibitors in patients with COVID-19 is needed; 5 randomized trials examining this issue are currently underway. There is no current scientific support for claiming that hypertension or its treatment with RAS inhibitors contribute to unfavorable outcomes in COVID-19.

title: COVID-19-Associated Bifacial Weakness with Paresthesia Subtype of Guillain-Barré Syndrome

text: We report a case of bifacial weakness with paresthesia, a recognized Guillain-Barré syndrome subtype characterized by rapidly progressive facial weakness and paresthesia without ataxia or other cranial neuropathies, which was temporally associated with antecedent coronavirus 2019 (COVID-19). This case highlights a potentially novel but critically important neurologic association of the COVID-19 disease process. Herein, we detail the clinicoradiologic work-up and diagnosis, clinical course, and multidisciplinary medical management of this patient with COVID-19. This case is illustrative of the increasingly recognized but potentially underreported neurologic manifestations of COVID-19, which must be considered and further investigated in this pandemic disease.


title: Advanced Pulmonary and Cardiac Support of COVID-19 Patients: Emerging Recommendations From ASAIO-A "Living Working Document"

text: The severe acute respiratory syndrome (SARS)-CoV-2 is an emerging viral pathogen responsible for the global coronavirus disease 2019 (COVID)-19 pandemic resulting in significant human morbidity and mortality. Based on preliminary clinical reports, hypoxic respiratory failure complicated by acute respiratory distress syndrome is the leading cause of death. Further, septic shock, late-onset cardiac dysfunction, and multiorgan system failure are also described as contributors to overall mortality. Although extracorporeal membrane oxygenation and other modalities of mechanical cardiopulmonary support are increasingly being utilized in the treatment of respiratory and circulatory failure refractory to conventional management, their role and efficacy as support modalities in the present pandemic are unclear. We review the rapidly changing epidemiology, pathophysiology, emerging therapy, and clinical outcomes of COVID-19; and based on these data and previous experience with artificial cardiopulmonary support strategies, particularly in the setting of infectious diseases, provide consensus recommendations from ASAIO. Of note, this is a "living document," which will be updated periodically, as additional information and understanding emerges.


title: Remdesivir (GS-5734) as a therapeutic option of 2019-nCOV main protease - in silico approach

text: 2019 - Novel Coronavirus (2019-nCOV), enclosed large genome positive-sense RNA virus characterized by crown-like spikes that protrude from their surface, and have a distinctive replication strategy. The 2019-nCOV belongs to the Coronaviridae family, principally consists of virulent pathogens showing zoonotic property, has emerged as a pandemic outbreak with high mortality and high morbidity rate around the globe and no therapeutic vaccine or drugs against 2019-nCoV are discovered till now. In this study, in silico methods and algorithms were used for sequence, structure analysis and molecular docking on Mpro of 2019-nCOV. The co-crystal structure of 2019-nCOV protease, 6LU7 have â¼99% identity with SARS-CoV protease. The 6LU7 residues, Cys145 and His164 are playing a significant role in replication and are essential for the survival of 2019-nCOV. Alongside, 2019-nCOV Mpro sequence is non-homologous to human host-pathogen. Complete genome sequence analysis, structural and molecular docking results revealed that Remdesivir is having a better binding affinity with -8.2 kcal/mol than the rest of protease inhibitors, and peptide. Remdesivir is strongly forming h-bonds with crucial Mpro residues, Cys145, and His164. Further, MD simulation analysis also confirmed, that these residues are forming H-bond with Remdesivir during 100 ns simulations run and found stable (â¼99%) by RMSD and RMSF. Thus, present in silico study at molecular approaches suggest that, Remdesivir is a potent therapeutic inhibitor against 2019-nCoV.Communicated by Ramaswamy H. Sarma.

title: A Public Health Laboratory Response to the COVID-19 Pandemic

text: An outbreak of coronavirus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (SARS-CoV-2) began in Wuhan, Hubei, China, in December 2019, and spread rapidly worldwide. The response by the Alberta Precision Laboratories, Public Health Laboratory (ProvLab), Alberta, Canada, included the development and implementation of nucleic acid detection based assays and dynamic changes in testing protocols for the identification of cases as the epidemic curve increased exponentially. This rapid response was essential to slow down and contain transmission and provide valuable time to the local health authorities to prepare appropriate response strategies. As of May 24, 2020, 236,077 specimens were tested with 6475 (2.74%) positives detected in the province of Alberta, Canada. Several commercial assays are now available; however, the response from commercial vendors to develop and market validated tests is a time-consuming process. In addition, the massive global demand made it difficult to secure a reliable commercial supply of testing kits and reagents.A public health laboratory serves a unique and important role in the delivery of health care. One of its functions is to anticipate and prepare for novel emerging pathogens with a plan for pandemic preparedness. Here we outline the response that involved the development and deployment of testing methodologies that evolved as SARS-CoV-2 spread world-wide, the challenges encountered, and mitigation strategies. We also provide insight into the organizational structure of how a public health response is coordinated in Alberta and its benefits.

title: The basic reproduction number and prediction of the epidemic size of the novel coronavirus (COVID-19) in Shahroud, Iran

text: The aim of this study was to estimate the basic reproduction number (R0) of COVID-19 in the early stage of the epidemic and predict the expected number of new cases in Shahroud in Northeastern Iran. The R0 of COVID-19 was estimated using the serial interval distribution and the number of incidence cases. The 30-day probable incidence and cumulative incidence were predicted using the assumption that daily incidence follows a Poisson distribution determined by daily infectiousness. Data analysis was done using 'earlyR' and 'projections' packages in R software. The maximum-likelihood value of R0 was 2.7 (95% confidence interval (CI): 2.1-3.4) for the COVID-19 epidemic in the early 14 days and decreased to 1.13 (95% CI 1.03-1.25) by the end of day 42. The expected average number of new cases in Shahroud was 9.0 ± 3.8 cases/day, which means an estimated total of 271 (95% CI: 178-383) new cases for the period between 02 April to 03 May 2020. By day 67 (27 April), the effective reproduction number (Rt), which had a descending trend and was around 1, reduced to 0.70. Based on the Rt for the last 21 days (days 46-67 of the epidemic), the prediction for 27 April to 26 May is a mean daily cases of 2.9 ± 2.0 with 87 (48-136) new cases. In order to maintain R below 1, we strongly recommend enforcing and continuing the current preventive measures, restricting travel and providing screening tests for a larger proportion of the population.


title: What do we know about the SARS-CoV-2 coronavirus in the environment?

text: In view of the current situation regarding the Covid-19 disease, a discussion is proposed on the need for research focusing on the presence and evolution of the SARS-CoV-2 virus in water, soils and other environmental compartments, reached through wastewater and sewage sludge spreading. Also, the evaluation of current treatments for wastewater and sewage sludge, as well as the eventual development of new specific techniques, based on sorption, nanotechnology, etc., would be of great interest for controlling the environmental dissemination of these viruses in the current and eventual future outbreaks.

title: Personalization of Hearing Aid Compression by Human-In-Loop Deep Reinforcement Learning

text: Existing prescriptive compression strategies used in hearing aid fitting are designed based on gain averages from a group of users which are not necessarily optimal for a specific user. Nearly half of hearing aid users prefer settings that differ from the commonly prescribed settings. This paper presents a human-in-loop deep reinforcement learning approach that personalizes hearing aid compression to achieve improved hearing perception. The developed approach is designed to learn a specific user's hearing preferences in order to optimize compression based on the user's feedbacks. Both simulation and subject testing results are reported which demonstrate the effectiveness of the developed personalized compression.


title: Implication of Inter-State Movement of Migrant Workers during COVID 19 Lockdown using Modified SEIR Model

text: A modified SEIR model is used in the paper to evaluate the effect of inter-state migrant worker transportation during the lockdown in India. The model considers different levels of COVID-19 transmission during travel, daily arrival rate and total migrant workers. Indian states with significant migrant workers are considered to estimate the rise in confirmed and active COVID-19 cases. It is observed that reduced daily arrival rate of migrant workers can help Uttar Pradesh and Bihar to lower the rise in confirmed and active cases. By the end of May, 2020, the daily arrival rate of migrant workers will have similar effect on Rajasthan. For the daily arrival rate of migrant workers considered, Madhya Pradesh may experience higher rise in confirmed and active cases. Maharashtra, on the other hand, may experience marginal rise in the confirmed and active cases. A stringent policy to screen migrant workers for possible trace COVID-19 virus prior to the travel and stricter isolation norm after reaching the destination state can be helpful in reducing the rise in confirmed and actives cases attributed to the migrant worker transportation.


title: Health-related concerns and precautions during the COVID-19 pandemic: A comparison of Canadians with and without underlying health conditions

text: BACKGROUND: The risk of experiencing adverse outcomes from the coronavirus disease 2019 (COVID-19), such as hospitalization, admission to intensive care units and death, is elevated for older individuals and those with certain underlying health conditions including diabetes, chronic conditions affecting lungs, heart or kidneys, and a compromised immune system. DATA AND METHODS: Data collected between March 29 and April 3, 2020 from the Canadian Perspectives Survey Series 1: Impacts of COVID-19 (n=4,627) were used to estimate the prevalence of underlying health conditions, health concerns and precautionary behaviours among Canadians aged 15 or older living in the provinces. Multivariate analyses examined associations between these variables after accounting for age, sex and education. RESULTS: Close to 1 in 4 Canadians (24%) had an underlying health condition that increased their risk of adverse outcomes from COVID-19. Overall, 36% of the population were very or extremely concerned about the impact of COVID-19 on their own health. Individuals with underlying health conditions had higher odds (odds ratio: 2.0, 95% confidence interval: 1.6 to 2.5) of being highly concerned than those without these conditions, after adjustment for demographic characteristics. High percentages of Canadians took precautions to reduce the risk of infection regardless of whether or not they had underlying health conditions. DISCUSSION: Health status was associated with higher levels of concern for one's own health in the early period of the COVID-19 pandemic. Most Canadians were taking precautions recommended by public health authorities to protect themselves and others.

title: Gastrointestinal and liver manifestations of COVID-19

text: The novel coronavirus 2 (SARS-CoV-2) has spread worldwide. While patients typically present with fever and symptoms of a respiratory illness, patients have also presented with gastrointestinal symptoms such as diarrhea, vomiting and abdominal pain. In addition, some patients were reported to have liver injury. In this article, we review gastrointestinal and liver aspects of COVID-19. In addition, we provide general gastroenterologists with guidance on the management of patients with gastrointestinal and liver disorders from COVID-19.


title: Current laboratory diagnostics of coronavirus disease 2019 (COVID-19)

text: Laboratory medicine provides an almost irreplaceable contribution to the diagnostic reasoning and managed care of most human pathologies. The novel coronavirus disease 2019 (COVID-19) is not an exception to this paradigm. Although the relatively recent emergence does not allow to draw definitive conclusions on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostics, some standpoints can be conveyed. First and foremost, it seems now clear that we will be living together with this virus for quite a long time, so that our vigilance and responsiveness against the emergence of new local outbreaks shall be maintained at the highest possible levels. The etiological diagnosis of COVID-19 is, and will remain for the foreseeable future, deeply based on direct identification of viral RNA by means of molecular biology techniques in biological materials, especially upper and lower respiratory tract specimens. Whether other materials, such as blood, urine, stools, saliva and throat washing, will become valid alternatives has not been unequivocally defined so far. As concerns serological testing, promising information can be garnered from preliminary investigations, showing that the vast majority of COVID-19 patients seem to develop a sustained immune response against the virus, characterized especially by emergence of anti-SARS-CoV-2 IgG and IgA, 1 to 2 weeks after the onset of fever and/or respiratory symptoms. Whether these antibodies will have persistent neutralizing activity against the virus is still to be elucidated on individual and general basis. The availability of rapid tests for detecting either viral antigens or anti-SARS-CoV-2 antibodies are a potentially viable opportunity for purposes of epidemiologic surveillance, though more information is needed on accuracy and reliability of these portable immunoassays.

title: Lack of cytomegalovirus (CMV)-specific cell-mediated immune response using QuantiFERON-CMV assay in CMV-seropositive healthy volunteers: fact not artifact

text: The QuantiFERON-CMV (QF) assay measures cell-mediated immunity against cytomegalovirus (CMV-CMI), which is particularly useful in individuals susceptible to CMV infection such as transplant patients. A positive QF result identifies patients that are better protected against CMV infection. However, the significance of a negative QF result in CMV-seropositive individuals needs to be clarified. CMV-CMI was analyzed in healthy subjects using the QF assay, and, in parallel, the Flow-cytometric Assay of Specific Cell-mediated Immune response in Activated whole blood (FASCIA). FASCIA assay measures T-cell proliferation using CMV lysate as stimulus whereas QF assay use a mix of peptides. A total of 93 healthy volunteers were enrolled, and 13/71 CMV-seropositive individuals (18.3%) showed humoral/cellular discordance using QF assay (CMV+ QF-). Interestingly, with FASCIA assay CD4+ and CD8+ T-cell proliferations were lower in CMV+ QF- than in CMV+ QF+ individuals. Furthermore, CMV+ QF- volunteers had a lower level of anti-CMV IgG than CMV+ QF+ subjects. Discordant CMV+ QF- volunteers can be defined as low responder individuals since they show lower CMV-specific humoral and cellular immune responses in comparison to CMV+ QF+ individuals. Immune discordance shows the high heterogeneity of immunity to CMV in healthy subjects.


title: Resource Reallocation during the COVID-19 Pandemic in a Suburban Hospital System: Implications for Outpatient Hip and Knee Arthroplasty

text: The COVID pandemic of 2020 has emerged as a global threat to patients, health care providers, and to the global economy. Owing to this particular novel and highly infectious strain of coronavirus, the rapid community spread and clinical severity of the subsequent respiratory syndrome created a substantial strain on hospitals and health care systems around the world. The rapid surge of patients presenting over a small period for emergent clinical care, admission to the hospital, and intensive care units with many requiring mechanically assisted ventilators for respiratory support demonstrated the potential to overwhelm health care workers, hospitals, and health care systems. The purpose of this article is to describe an effective system for redeployment of health care supplies, resources, and personnel to hospitals within a suburban academic hospital system to optimize the care of COVID patients, while treating orthopedic patients in an equally ideal setting to maximize their surgical and clinical care. This article will provide a particular focus on the current and future role of a specialty hip and knee hospital and its partnering ambulatory surgery center in the context of an outpatient arthroplasty program.

title: The prevalence and influencing factors in anxiety in medical workers fighting COVID-19 in China: a cross-sectional survey

text: The coronavirus disease 2019 (COVID-19) outbreak caused by the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2 virus) has been sustained in China since December 2019, and has become a pandemic. The mental health of frontline medical staff is a concern. In this study, we aimed to identify the factors influencing medical worker anxiety in China during the COVID-19 outbreak. We conducted a cross-sectional study to estimate the prevalence of anxiety among medical staff in China from 10 February 2020 to 20 February 2020 using the Zung Self-rating Anxiety Scale (SAS) to assess anxiety, with the criteria of normal (â©½49), mild (50-59), moderate (60-70) and severe anxiety (â©¾70). We used multivariable linear regression to determine the factors (e.g. having direct contact when treating infected patients, being a medical staff worker from Hubei province, being a suspect case) for anxiety. We also used adjusted models to confirm independent factors for anxiety after adjusting for gender, age, education and marital status. Of 512 medical staff in China, 164 (32.03%) had had direct contact treating infected patients. The prevalence of anxiety was 12.5%, with 53 workers suffering from mild (10.35%), seven workers suffering from moderate (1.36%) and four workers suffering from severe anxiety (0.78%). After adjusting for sociodemographic characteristics (gender, age, education and marital status), medical staff who had had direct contact treating infected patients experienced higher anxiety scores than those who had not had direct contact (ß value = 2.33, confidence interval (CI) 0.65-4.00; P = 0.0068). A similar trend was observed in medical staff from Hubei province, compared with those from other parts of China (ß value = 3.67, CI 1.44-5.89; P = 0.0013). The most important variable was suspect cases with high anxiety scores, compared to non-suspect cases (ß value = 4.44, CI 1.55-7.33; P = 0.0028). In this survey of hospital medical workers during the COVID-19 outbreak in China, we found that study participants experienced anxiety symptoms, especially those who had direct clinical contact with infected patients; as did those in the worst affected areas, including Hubei province; and those who were suspect cases. Governments and healthcare authorities should proactively implement appropriate psychological intervention programmes, to prevent, alleviate or treat increased anxiety.


title: Perspectives on monoclonal antibody therapy as potential therapeutic intervention for Coronavirus disease-19 (COVID-19)

text: Last decade witnessed the outbreak of many life-threatening human pathogens including Nipah, Ebola, Chikungunya, Zika, Middle East respiratory syndrome coronavirus (MERS-CoV), Severe Acute respiratory syndrome coronavirus (SARS-CoV) and more recently novel coronavirus (2019-nCoV or SARS-CoV-2). The disease condition associated with novel coronavirus, referred to as Coronavirus disease (COVID-19). The emergence of novel coronavirus in 2019 in Wuhan, China marked the third highly pathogenic coronavirus infecting humans in the 21st century. The continuing emergence of coronaviruses at regular intervals poses a significant threat to human health and economy. Ironically, even after a decade of research on coronavirus, still there are no licensed vaccines or therapeutic agents to treat coronavirus infection which highlights an urgent need to develop effective vaccines or post-exposure prophylaxis to prevent future epidemics. Several clinical, genetic and epidemiological features of COVID-19 resemble SARS-CoV infection. Hence, the research advancements on SARS-CoV treatment might help scientific community in quick understanding of this virus pathogenesis and develop effective therapeutic/prophylactic agents to treat and prevent this infection. Monoclonal antibodies represent the major class of biotherapeutics for passive immunotherapy to fight against viral infection. The therapeutic potential of monoclonal antibodies has been well recognized in the treatment of many diseases. Here, we summarize the potential monoclonal antibody based therapeutic intervention for COVID-19 by considering the existing knowledge on the neutralizing monoclonal antibodies against similar coronaviruses SARS-CoV and MERS-CoV. Further research on COVID-19 pathogenesis could identify appropriate therapeutic targets to develop specific anti-virals against this newly emerging pathogen.

title: Implementation and analysis of a telephone support service during COVID-19

text: BACKGROUND: During the COVID-19 pandemic, it has been essential for occupational health services (OHS) providers to react rapidly to increased demand and to utilize resources in novel ways. The impact of the COVID-19 pandemic on the psychological well-being of staff is already identified as an area of high risk; therefore, providing timely access to psychological support may be vital, although limited evidence is available on how these risks are best managed. AIMS: To describe implementation and analysis of a psychology-led COVID-19 telephone support line in a National Health Service OHS. METHODS: Data from calls made to the support line were collected over the first 4 weeks of service implementation. Numerical data including frequency of calls and average waiting time were first considered. A content analysis was then conducted on call notes to identify prevalence of themes. RESULTS: Six hundred and fifty-five calls were received, and 362 notes included sufficient information for use within the content analysis. Frequency of calls peaked within the first week followed by a reduction in the number of calls received per day over time. Most calls included discussion around clarification of guidance (68%) with a smaller subset of calls offering support around anxiety (29%). Prevalence of themes did not appear to change over time. CONCLUSIONS: Clear and timely information is vital to support the well-being of healthcare staff. A psychologically informed telephone support line was a good use of occupational health service resources in the interim while more tailored advice and services could be established.


title: A Big Data Based Framework for Executing Complex Query Over COVID-19 Datasets (COVID-QF)

text: COVID-19's rapid global spread has driven innovative tools for Big Data Analytics. These have guided organizations in all fields of the health industry to track and minimized the effects of virus. Researchers are required to detect coronaviruses through artificial intelligence, machine learning, and natural language processing, and to gain a complete understanding of the disease. COVID-19 takes place in different countries in the world, with which only big data application and the work of NOSQL databases are suitable. There is a great number of platforms used for processing NOSQL Databases model like: Spark, H2O and Hadoop HDFS/MapReduce, which are proper to control and manage the enormous amount of data. Many challenges faced by large applications programmers, especially those that work on the COVID-19 databases through hybrid data models through different APIs and query. In this context, this paper proposes a storage framework to handle both SQL and NOSQL databases named (COVID-QF) for COVID-19 datasets in order to treat and handle the problems caused by virus spreading worldwide by reducing treatment times. In case of NoSQL database, COVID-QF uses Hadoop HDFS/Map Reduce and Apache Spark. The COVID-QF consists of three Layers: data collection layer, storage layer, and query Processing layer. The data is collected in the data collection layer. The storage layer divides data into collection of data-saving and processing blocks, and it connects the Connector of the spark with different databases engine to reduce time of saving and retrieving. While the Processing layer executes the request query and sends results. The proposed framework used three datasets increased for time for COVID-19 data (COVID-19-Merging, COVID-19-inside-Hubei and COVID-19-ex-Hubei) to test experiments of this study. The results obtained insure the superiority of the COVID-QF framework.

text: Due to the current pandemic of respiratory disease known as coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus, many patients with confirmed or suspected COVID-19 infection will require elective surgery, surgery that cannot be postponed, or emergency surgical treatment. In these situations, special measures need to be adopted in order to minimize the possibility of transmission between patients, exposure of healthcare personnel and the development of postoperative complications. This document explains the main principles to consider when managing confirmed or suspected COVID-19 patients during evaluation as well as when surgical treatment is required.


title: Predictors of mortality for patients with COVID-19 pneumonia caused by SARS-CoV-2: a prospective cohort study

text: The aim of this study was to identify factors associated with the death of patients with COVID-19 pneumonia caused by the novel coronavirus SARS-CoV-2.All clinical and laboratory parameters were collected prospectively from a cohort of patients with COVID-19 pneumonia who were hospitalised to Wuhan Pulmonary Hospital (Wuhan City, Hubei Province, China) between 25 December 2019 and 7 February 2020. Univariate and multivariate logistic regression was performed to investigate the relationship between each variable and the risk of death of COVID-19 pneumonia patients.In total, 179 patients with COVID-19 pneumonia (97 male and 82 female) were included in the present prospective study, of whom 21 died. Univariate and multivariate logistic regression analysis revealed that age ≥65â years (OR 3.765, 95% CI 1.146â17.394; p=0.023), pre-existing concurrent cardiovascular or cerebrovascular diseases (OR 2.464, 95% CI 0.755â8.044; p=0.007), CD3+CD8+ T-cells ≤75â cells·µL-1 (OR 3.982, 95% CI 1.132â14.006; p<0.001) and cardiac troponin I ≥0.05â ng·mL-1 (OR 4.077, 95% CI 1.166â14.253; p<0.001) were associated with an increase in risk of mortality from COVID-19 pneumonia. In a sex-, age- and comorbid illness-matched case-control study, CD3+CD8+ T-cells ≤75â cells·µL-1 and cardiac troponin I ≥0.05â ng·mL-1 remained as predictors for high mortality from COVID-19 pneumonia.We identified four risk factors: age ≥65â years, pre-existing concurrent cardiovascular or cerebrovascular diseases, CD3+CD8+ T-cells ≤75â cells·µL-1 and cardiac troponin I ≥0.05â ng·mL-1 The latter two factors, especially, were predictors for mortality of COVID-19 pneumonia patients.

Symptomatic (palliative) treatment is of fundamental importance both in conjuncture with life-sustaining interventions and in end of life care. Based on the evidence to date, there are several treatment options to consider for the relief of fever (acetaminophen, NSAID, oral glucocorticoids), cough (morphine), breathlessness (morphine, oxygen, fan), anxiety (benzodiazepines) and pain (NSAID, morphine). Top priorities include precautions to protect staff and people at-risk from infection and planning how to provide adequate treatment for each individual depending on setting, including palliative care.

title: Recommendations for the prevention, mitigation and containment of the emerging SARS-CoV-2 (COVID-19) pandemic in haemodialysis centres

text: COVID-19, a disease caused by a novel coronavirus, is a major global human threat that has turned into a pandemic. This novel coronavirus has specifically high morbidity in the elderly and in comorbid populations. Uraemic patients on dialysis combine an intrinsic fragility and a very frequent burden of comorbidities with a specific setting in which many patients are repeatedly treated in the same area (haemodialysis centres). Moreover, if infected, the intensity of dialysis requiring specialized resources and staff is further complicated by requirements for isolation, control and prevention, putting healthcare systems under exceptional additional strain. Therefore, all measures to slow if not to eradicate the pandemic and to control unmanageably high incidence rates must be taken very seriously. The aim of the present review of the European Dialysis (EUDIAL) Working Group of ERA-EDTA is to provide recommendations for the prevention, mitigation and containment in haemodialysis centres of the emerging COVID-19 pandemic. The management of patients on dialysis affected by COVID-19 must be carried out according to strict protocols to minimize the risk for other patients and personnel taking care of these patients. Measures of prevention, protection, screening, isolation and distribution have been shown to be efficient in similar settings. They are essential in the management of the pandemic and should be taken in the early stages of the disease.

title: [From SARS to COVID-19: pathogens, receptor, pathogenesis and principles of the treatment]

text: COVID-19 is an infectious disease caused by 2019-nCoV and characterizes as an atypical pneumonia. Since 2019-nCoV is a newly emerging virus, the pathogenesis of COVID-19 is not well known. Most patients had a self-limited course, and some became severe even death. In this review, the authors compared two coronavirus outbreaks during the past two decades: the SARS-CoV and 2019-nCoV. Among the biological nature of the pathogens, viral receptor distribution on the human cells, and the pathological findings in the targeted organs and clinical features of the patients with the diseases, found similarities and differences between the two diseases had been found. Due to the shared receptor ACE2 and the pathological similarities of the SARS-CoV and 2019-nCoV diseases,authors proposed a pathogenesis model for COVID-19. Like the SARS-CoV disease, COVID-19 is a systematic disease and targets the lungs, vasculatures, and the immune system. The basic pathogenesis involves two interlinked processes: a severe lung inflammation and immune deficiency, both of which were related to an inappropriate immune response and over-production of cytokines. Thus, treatment approaches should include antiviral and anti-proinflammatory cytokines, anti-infectious and life support therapies, especially in patients with severe diseases.


title: The human genetic determinism of life-threatening infectious diseases: genetic heterogeneity and physiological homogeneity?

text: Multicellular eukaryotes emerged late in evolution from an ocean of viruses, bacteria, archaea, and unicellular eukaryotes. These macroorganisms are exposed to and infected by a tremendous diversity of microorganisms. Those that are large enough can even be infected by multicellular fungi and parasites. Each interaction is unique, if only because it operates between two unique living organisms, in an infinite diversity of circumstances. This is neatly illustrated by the extraordinarily high level of interindividual clinical variability in human infections, even for a given pathogen, ranging from a total absence of clinical manifestations to death. We discuss here the idea that the determinism of human life-threatening infectious diseases can be governed by single-gene inborn errors of immunity, which are rarely Mendelian and frequently display incomplete penetrance. We briefly review the evidence in support of this notion obtained over the last two decades, referring to a number of focused and thorough reviews published by eminent colleagues in this issue of Human Genetics. It seems that almost any life-threatening infectious disease can be driven by at least one, and, perhaps, a great many diverse monogenic inborn errors, which may nonetheless be immunologically related. While the proportions of monogenic cases remain unknown, a picture in which genetic heterogeneity is combined with physiological homogeneity is emerging from these studies. A preliminary sketch of the human genetic architecture of severe infectious diseases is perhaps in sight.


title: Fistulojejunostomy for Chronic Fistula After Sleeve Gastrectomy

text: The most dreadful complication after sleeve gastrectomy (SG) is staple line leak. Its rate varies between 1 and 2%. With the development of interventional endoscopy, its treatment is currently fairly standardized and allows healing in the majority of cases without revisional surgery. However, if endoscopic treatment fails, surgical treatment becomes unavoidable. Fistulojejunostomy is a surgical option in the management of chronic fistula after SG. Laparoscopic fistulojejunostomy in a patient with chronic fistula after SG is difficult but feasible. This procedure allows complete healing and nutritional recovery in the case of failure of other endoscopic modalities.

title: COVID-19 and MS disease-modifying therapies

text: OBJECTIVE: To address concerns regarding the effect of MS disease-modifying therapies (DMTs) on the expression of coronavirus 2019 (COVID-19). METHODS: Review of the current state of knowledge regarding the viral etiology of COVID-19, mechanisms of injury by SARS-CoV-2 infection, and the effect of individual DMTs on the risk of infection and COVID-19 disease expression. RESULTS: Although data are limited, MS DMTs do not obviously increase the risk of acquiring symptomatic SARS-CoV-2 infection. The severe morbidity and mortality of SARS-CoV-2 appear to be largely the consequence of an overly robust immune response rather than the consequence of unchecked viral replication. The effects of specific MS DMTs on the immune response that may increase the risk of impaired viral clearance and their potential counterbalancing beneficial effects on the development of COVID-19-associated acute respiratory distress syndrome are reviewed. CONCLUSION: Although there is currently insufficient real-world experience to definitively answer the question of the effect of a specific MS DMT on COVID-19, registries presently in nascent form should provide these answers. This review provides an approach to addressing these concerns while the data are being accumulated. Early insights suggest that the risk of infection and associated morbidity of COVID-19 in this population is little different than that of the population at large.

title: Association of a Public Health Campaign About Coronavirus Disease 2019 Promoted by News Media and a Social Influencer With Self-reported Personal Hygiene and Physical Distancing in the Netherlands

text: Importance: In the absence of a vaccine and therapeutic agent, personal hygiene and physical distancing are essential measures to contain the coronavirus disease 2019 pandemic. Objective: To determine whether a social media campaign, targeted at the gaps in behavior on personal hygiene and physical distancing and distributed nationwide via digital news media, may be an effective method to improve behavior and help to inhibit person-to-person transmission of severe acute respiratory syndrome coronavirus 2. Design, Setting, and Participants: This survey study was designed to uncover self-reported gaps in behavior regarding personal hygiene and physical distancing in the Netherlands. A diagnostic survey was distributed by a large national newspaper (De Telegraaf) and a popular social influencer (Govert Sweep) on March 17, 2020, and was completed by 16â¯072 participants. Analysis of these outcomes showed that coughing and sneezing in the elbow was done well, but that handwashing, face touching, and physical distancing showed serious gaps compared with advised behavior. This diagnostic information was used to design infographics and a video targeted at repairing these gaps in behavior. The video and infographics were distributed on a national level on March 21, 2020, followed by a postcampaign survey to measure the results on March 24, 2020. Data analysis was performed from March to April 2020. Exposure: Exposed participants were those who viewed the infographics and/or video. Main Outcomes and Measures: Improvement on the extent of handwashing in all areas, handwashing duration of 20 seconds or longer, awareness on face touching, and physical distancing were measured according to responses on the postcampaign survey. Results: A total of 17â¯189 participants (mean [SD] age, 47.61 [13.57] years; 9100 women [52.9%]) responded to the postcampaign survey. The news article in De Telegraaf was read more than 2 million times, and the influencer video was watched more than 80â¯000 times. Cross-sectional analysis of the postcampaign survey using logistic regression correcting for age, gender, and educational level showed that exposure to the video plus infographics (827 participants) (adjusted odds ratio [OR], 2.14; 95% CI, 1.83-2.50; P < .001) and to the infographics alone (11â¯348 participants) (adjusted OR, 1.31; 95% CI, 1.22-1.40; P < .001) were positively associated with washing hands in all areas compared with the unexposed group (4751 participants). In addition, exposure to the video plus infographics (adjusted OR, 1.86; 95% CI, 1.59-2.16; P < .001) and to the infographics alone (adjusted OR, 1.27; 95% CI, 1.19-1.36; P < .001) were positively associated with washing hands long enough compared with the unexposed group. Exposure to the video alone was not associated with improved handwashing. Compared with the unexposed group, exposure to the infographics alone and video plus infographics were associated with improvements in physical distancing when the participant had COVID-19 syptoms (infographics alone, adjusted OR, 1.10; 95% CI, 1.03-1.17; P = .006; video plus infographics, adjusted OR, 0.79; 95% CI, 0.69-0.91; P = .001) and face touching (infographics alone, adjusted OR, 1.29; 95% CI, 1.22-1.38; P < .001; infographics and video, adjusted OR, 1.49, 95% CI, 1.30-1.71; P < .001). Conclusions and Relevance: These findings suggest that a targeted behavioral change campaign, promoted by a news platform and social media, was associated with self-reported improvement in personal hygiene with the aim to prevent person-to-person transmission of severe acute respiratory syndrome coronavirus 2. This method of evidence-based campaigning may be an effective way to improve critical public health issues, such as the coronavirus disease 2019 pandemic.

title: Epidemiologic characteristics of traumatic fractures in elderly patients during the outbreak of coronavirus disease 2019 in China

text: PURPOSE: This study aimed to describe the epidemiologic characteristics of fracture in the elderly during the COVID-19. METHODS: This was a retrospective multi-centre study, which included patients who sustained fractures between 20 January and 19 February 2020. The collected data included patients' demographics (age and gender), injury-related (injury type, fracture location, injury mechanism, places where fracture occurred), and treatment modality. SPSS 23.0 was used to describe the data and perform some analysis. RESULTS: A total of 436 patients with 453 fractures were included; there were 153 males and 283 females, with an average age of 76.2 years (standard deviation, SD, 7.7 years; 65 to 105). For either males or females, 70-74 years was the most commonly involved age group. A total of 317 (72.7%) patients had their fractures occurring at home. Among 453 fractures, there were 264 (58.3%) hip fractures, accounting for 58.3%. Fall from standing height was the most common cause of fracture, making a proportion of 89.4% (405/453). Most fractures (95.8%, 434/453) were treated surgically, and 4.2% (19/453) were treated by plaster fixation or traction. Open reduction and internal fixation (ORIF) was the most used surgical method, taking a proportion of 49.2% (223/453). CONCLUSION: These findings highlighted the importance of primary prevention (home prevention) measures and could be used for references for individuals, health care providers, or health administrative department during the global pandemic of COVID-19.


title: Infusion of Convalescent Plasma Is Associated with Clinical Improvement in Critically Ill Patients with Covid-19: a Pilot Study

text: Background: The ideal treatment of coronavirus disease (COVID)-19 has yet to be defined, but convalescent plasma (CoPla) has been successfully employed. Objective: The objective of the study was to study the safety and outcomes of the administration of CoPla to individuals with severe COVID-19 in an academic medical center. Methods: Ten patients were prospectively treated with plasma from COVID-19 convalescent donors. Results: Over 8 days, the sequential organ failure assessment score dropped significantly in all patients, from 3 to 1.5 (p = 0.014); the Kirby index (PaO2/FiO2) score increased from 124 to 255, (p < 0.0001), body temperature decreased significantly from 38.1 to 36.9°C (p = 0.0058), and ferritin levels also dropped significantly from 1736.6 to 1061.8 ng/ml (p = 0.0001). Chest X-rays improved in 7/10 cases and in 6/10, computerized tomography scans also revealed improvement of the lung injury. Decreases in C-reactive protein and D-dimer levels were also observed. Three of five patients on mechanical ventilation support could be extubated, nine were transferred to conventional hospital floors, and six were sent home; two patients died. The administration of CoPla had no side effects and the 24-day overall survival was 77%. Conclusions: Although other treatments were also administered to the patients and as a result data are difficult to interpret, it seems that the addition of CoPla improved pulmonary function.


title: Impact of the COVID-19 Pandemic on Mental Health and Social Support among Adult Egyptians

text: The psychological impact of outbreaks on individuals includes an intense and wide range of psychiatric morbidities. People are likely to experience feelings as; worry about being infected or getting sick, increased self-blame, and helplessness. This study aimed to assess the impact of COVID-19 on mental health and social support among Egyptian adults during the period of the pandemic. This is a cross-sectional observational study using an anonymous online questionnaire. The survey was conducted through a link shared on social networking sites. It was conducted from 2 May 2020 to 9 May 2020. The general populations of the Egyptian adults were included by using convenience and snowball sampling technique (510 adults). Impact Event scale mean 34.3 ± 15. About 211 (41.4%) suffered a severe impact. There was an increase in stress from work in 174 (34.1%), financial stress in 284 (55.7%), and stress from home in 320 (62.7%). Half of them felt horrified and helpless in 275 (53.9%), and 265 (52%) respectively, while 338 (66.3%) felt apprehensive. only 24.2% reported increased support from friends, while increased support from family members in 207 (40.6%). 46.5% shared their feelings with family members, while 176 (34.5%) shared with others. Caring for family members' feelings increased in 330 (64.7%). Age and rural residency were negative predictors for the impact of event score, while female gender or presence of chronic condition was a positive predictor for the impact of event score. Covid-19 pandemic has a great psychological impact on adult Egyptians and affected social support.

text: OBJECTIVE: To investigate the clinical outcome of patients with moderate type of coronavirus disease 2019 (COVID-19) after discharge by retesting viral nucleic acid. METHODS: Seven patients with moderate COVID-19 met the discharge criteria enacted by National Health Commission were quarantined in hospital for 7 days, then continuously quarantined at home for 4 weeks after discharged. During the quarantined period, the symptoms and signs were documented, and sputum or nasal swab and feces samples were collected to test SARS-CoV-2 nucleic acid by RT-PCR method. RESULTS: There was no symptoms and signs during the quarantine period in all 7 patients. However, respiratory swabs from 3 patients were confirmed positive of SARS-CoV-2 nucleic acid at 5 to 7 days after they met the discharge criteria. CONCLUSIONS: There is a relatively high incidence of positive viral nucleic acid in patients met the discharge criteria, and it is suggested that patients met the current discharge criteria should be quarantined in hospital for another 7 days and the follow-up viral testing is necessary.

title: L'embolia polmonare come complicanza tardiva della polmonite da SARS-CoV-2: una serie di casi clinici./ [Late occurrence of pulmonary embolsim in SARS-CoV-2 pneumonia: a case series]

text: Several studies suggested that the acute phase of SARS-CoV-2 infection may be associated with a hypercoagulable state and increased risk for venous thromboembolism but the incidence of thrombotic complications in the late phase of the disease is currently unknown. The present article describes three cases of patients with SARS-CoV-2 pneumonia and late occurrence of pulmonary embolism. Case 1: a 57-year-old man diagnosed with pulmonary embolism and type B aortic dissection after 12 days from SARS-CoV-2 pneumonia. Laboratory panel at the time of pulmonary embolism showed no signs of ongoing inflammation but only an elevated D-dimer. Case 2: a 76-year-old man with a diagnosis of SARS-CoV-2 pneumonia followed by pulmonary embolism 20 days later, high-resolution computed tomography on that time showed a partial resolution of crazy paving consolidation. Case 3: a 77-year-old man with SARS-CoV-2 pneumonia who developed a venous thromboembolic event despite thromboprophylaxis with low molecular weight heparin. Also in this patients no markers of inflammation were present at the time of complication.The present cases raise the possibility that in SARS-CoV-2 infection the hypercoagulable state may persist over the active inflammation phase and cytokine storm. These findings suggest a role for medium-long term therapeutic anticoagulation started at the time of SARS-CoV-2 pneumonia diagnosis.

Corona virus disease-19 (COVID-19) presenting as conjunctivitis: atypically high-risk during a pandemic


title: Novel wastewater surveillance strategy for early detection of coronavirus disease 2019 hotspots

text: The novel coronavirus disease 2019, a pandemic of global concern, caused by the novel severe acute respiratory syndrome coronavirus 2 has severely revealed the need for public monitoring and efficient screening techniques. Despite the various advancements made in the medical and research field, containment of this virus has proven to be difficult on several levels. As such, it is a necessary requirement to identify possible hotspots in the early stages of any disease. Based on previous studies carried out on coronaviruses, there is a high likelihood that severe acute respiratory syndrome coronavirus 2 may also survive in wastewater. Hence, we propose the use of nanofiber filters as a wastewater pretreatment routine and upgradation of existing wastewater evaluation and treatment systems to serve as a beneficial surveillance tool.


title: Psychological intervention on COVID-19: A protocol for systematic review and meta-analysis

text: INTRODUCTION: COVID-19 is novel coronavirus infection in 2019. Many reports suggested that psychological intervention is playing a positive role in COVID-19 treatment, but there is no high-quality evidence to prove its effects. This paper reports the protocol of a systematic review and meta-analysis to clarify effectiveness of psychological intervention during the treatment of COVID-19. METHODS AND ANALYSIS: The following electronic databases will be used by 2 independent reviewers: Web of Science, Embase, Cochrane Library, PubMed, Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, Chinese Scientific Journal Database, Wan fang Database, ClinicalTrials, WHO Trials, and Chinese Clinical Trial Registry. The randomised controlled trials of psychological intervention on COVID-19 will be searched in the databases by 2 researchers independently. Clinical recovery time and effective rate will be assessed as the primary outcomes. Changes of patients physical condition (1. Time until COVID-19 RT-PCR negative in upper respiratory tract specimen; 2. Time until cough reported as mild or absent; 3. Time until dyspnea reported as mild or absent; 4. Frequency of requiring supplemental oxygen or non-invasive ventilation; 5. Frequency of requiring respiratory; 6. Incidence of severe cases; 7. Proportion of re-hospitalization or admission to ICU; 8. All-cause mortality; 9. Frequency of seriously adverse events) and changes of psychological condition (such as: SRQ-20, PHQ-9, GAD-7, Hamilton Depression Scale, Hamilton Anxiety Scale) will be assessed as the secondary outcomes. For dichotomous outcomes, such as effective rate, data will be expressed as risk ratio (RR) with 95% confidence intervals (CIs). For continuous outcomes, weighted mean differences (WMD) or standardized mean differences (SMD) will be calculated. Fixed effect model will be used for evaluating efficiency. Considering clinical heterogeneity, random effect model will be used for continuous outcomes. RESULTS: Relevant studies will be used to evaluate whether psychological intervention is effective for COVID-19. CONCLUSION: This study will provide reliable evidence for psychological intervention on COVID-19. PROSPERO REGISTRATION NUMBER: CRD42020178699.

The impact of Covid-19 pandemic on elderly mental health


title: Knowledge, attitudes and practices of COVID-19 among income-poor households in the Philippines: A cross-sectional study

text: Background: The presence of COVID-19 in low- and middle-income countries (LMICs) is raising important concerns about effective pandemic response and preparedness in the context of fragile health systems and the pervasiveness of misinformation. The objective of this study was to gain an understanding of how COVID-19 was perceived by households experiencing extreme poverty in the Philippines. Methods: This study was conducted in partnership with International Care Ministries (ICM), a Philippine-based non-governmental organization (NGO) that runs a poverty-alleviation program called Transform targeted towards extreme low-income households. We integrated knowledge, attitudes, and practices (KAP) questions into ICM's cross-sectional program monitoring and evaluation systems from February 20 through March 13, 2020. Frequencies and proportions were calculated to describe the respondents' responses, and the Kruskal-Wallis test and binomial logistic regression were undertaken to determine the socio-demographic characteristics associated with COVID-19 KAPs. Results: In total, 2224 respondents from 166 communities in rural, urban and coastal settings were surveyed. Although the survey was administered during the earlier stages of the pandemic, 94.0% of respondents had already heard of COVID-19. Traditional media sources such as television (85.5%) and radio (56.1%) were reported as the main sources of information about the virus. Coughing and sneezing were identified as a transmission route by 89.5% of respondents, while indirect hand contact was the least commonly identified transmission route, recognized by 72.6% of respondents. Handwashing was identified by 82.2% of respondents as a preventive measure against the virus, but social distancing and avoiding crowds were only identified by 32.4% and 40.6%, respectively. Handwashing was the most common preventive practice in response to COVID-19, adopted by 89.9% of respondents. A greater number of preventive measures were taken by those with more knowledge of potential transmission routes. Conclusions: There is a need for targeted health education as a response strategy to COVID-19 in low-income settings, and it is important that strategies are contextually relevant. Understanding KAPs among populations experiencing extreme poverty will be important as tailored guidance for public health response and communication strategies are developed for LMICs.


Reducing droplet spread during airway manipulation: lessons from the COVID-19 pandemic in Singapore


title: Psychological Outcomes Associated with Stay-at-Home Orders and the Perceived Impact of COVID-19 on Daily Life

text: The COVID-19 pandemic has resulted in the widespread implementation of extraordinary physical distancing interventions (e.g., stay-at-home orders) to slow the spread of the virus. Although vital, these interventions may be socially and economically disruptive, contributing to adverse psychological outcomes. This study examined relations of both stay-at-home orders and the perceived impact of COVID-19 on daily life to psychological outcomes (depression, health anxiety, financial worry, social support, and loneliness) in a nationwide U.S. community adult sample (N = 500; 47% women, mean age = 40). Participants completed questionnaires assessing psychological outcomes, stay-at-home order status, and COVID-19's impact on their daily life. Being under a stay-at-home order was associated with greater health anxiety, financial worry, and loneliness. Moreover, the perceived impact of COVID-19 on daily life was positively associated with health anxiety, financial worry, and social support, but negatively associated with loneliness. Findings highlight the importance of social connection to mitigate negative psychological consequences of the COVID-19 pandemic.

title: Genomics functional analysis and drug screening of SARS-CoV-2

text: A novel coronavirus appeared in Wuhan, China has led to major outbreaks. Recently, rapid classification of virus species, analysis of genome and screening for effective drugs are the most important tasks. In the present study, through literature review, sequence alignment, ORF identification, motif recognition, secondary and tertiary structure prediction, the whole genome of SARS-CoV-2 were comprehensively analyzed. To find effective drugs, the parameters of binding sites were calculated by SeeSAR. In addition, potential miRNAs were predicted according to RNA base-pairing. After prediction by using NCBI, WebMGA and GeneMark and comparison, a total of 8 credible ORFs were detected. Even the whole genome have great difference with other CoVs, each ORF has high homology with SARS-CoVs (>90%). Furthermore, domain composition in each ORFs was also similar to SARS. In the DrugBank database, only 7 potential drugs were screened based on the sequence search module. Further predicted binding sites between drug and ORFs revealed that 2-(N-Morpholino)-ethanesulfonic acid could bind 1# ORF in 4 different regions ideally. Meanwhile, both benzyl (2-oxopropyl) carbamate and 4-(dimehylamina) benzoic acid have bene demonstrated to inhibit SARS-CoV infection effectively. Interestingly, 2 miRNAs (miR-1307-3p and miR-3613-5p) were predicted to prevent virus replication via targeting 3'-UTR of the genome or as biomarkers. In conclusion, the novel coronavirus may have consanguinity with SARS. Drugs used to treat SARS may also be effective against the novel virus. In addition, altering miRNA expression may become a potential therapeutic schedule.

title: Infertility and reproductive rights after the COVID-19 pandemic

text: Coronavirus disease 2019 (COVID-19) was declared a pandemic on 11 March 2020 by the World Health Organization, halting the principal income activities worldwide. The International Monetary Fund predicts that the imminent economic recession will be worse than the global financial crisis of 2008, which severely affected the economy of Southern European countries such as Greece, Italy and Spain. There was then an abysmal drop in the Spanish yearly population growth curve as families could not afford to have children in that economic context; this only worsened the already existing demographic problems in that Spain has a constantly ageing population and one of the lowest fertility indicators in Europe. Taking into consideration that female age is the most important independent variable of success at the time of conception, probably thousands of potentially fertile couples were lost while waiting for more promising circumstances. With the COVID-19 pandemic a similar situation is being faced, where reproductive rights are imperiled by not being able to choose when to have children due to economic coercion. Therefore, governments worldwide should take measures to palliate the possible sociodemographic crisis that will follow the economic recession and try to ease the burden that many families might face during the following years.

text: After successfully avoiding the situations experienced by some countries, Australasian EDs now face a future in which the ongoing threat of COVID-19 is added to the traditional challenges in providing quality emergency care. The contribution of emergency medicine to the national containment strategy adds a new dimension to the demands placed on emergency medicine in Australia and similarly, to the elimination strategy employed in New Zealand. These demands will best be met by a considered, planned and resourced approach that will challenge traditional measures of 'ED efficiency'.


title: Coronavirus disease 2019: a bibliometric analysis and review

text: OBJECTIVE: On December 8, 2019, many cases of pneumonia with unknown etiology were first reported in Wuhan, China, subsequently identified as a novel coronavirus infection aroused worldwide concern. As the outbreak is ongoing, more and more researchers focused interest on the COVID-19. Therefore, we retrospectively analyzed the publications about COVID-19 to summarize the research hotspots and make a review, to provide reference for researchers in the world. MATERIALS AND METHODS: We conducted a search in PubMed using the keywords "COVID-19" from inception to March 1, 2020. Identified and analyzed the data included title, corresponding author, language, publication time, publication type, research focus. RESULTS: 183 publications published from 2020 January 14 to 2020 February 29 were included in the study. The first corresponding authors of the publications were from 20 different countries. Among them, 78 (42.6%) from the hospital, 64 (35%) from the university and 39 (21.3%) from the research institution. All the publications were published in 80 different journals. Journal of Medical Virology published most of them (n=25). 60 (32.8%) were original research, 29 (15.8%) were review, 20 (10.9%) were short communications. 68 (37.2%) epidemiology, 49 (26.8%) virology and 26 (14.2%) clinical features. CONCLUSIONS: According to our review, China has provided a large number of research data for various research fields, during the outbreak of COVID-19. Most of the findings play an important role in preventing and controlling the epidemic around the world. With research on the COVID-19 still booming, new vaccine and effective medicine for COVID-19 will be expected to come out in the near future with the joint efforts of researchers worldwide.


Wuhan Coronavirus (Covid-19): Yet Another Bat Virus Zoonotic


title: Mobile phone location data reveal the effect and geographic variation of social distancing on the spread of the COVID-19 epidemic

text: The emergence of SARS-CoV-2 and the coronavirus infectious disease (COVID-19) has become a pandemic. Social (physical) distancing is a key non-pharmacologic control measure to reduce the transmission rate of SARS-COV-2, but high-level adherence is needed. Using daily travel distance and stay-at-home time derived from large-scale anonymous mobile phone location data provided by Descartes Labs and SafeGraph, we quantify the degree to which social distancing mandates have been followed in the U.S. and its effect on growth of COVID-19 cases. The correlation between the COVID-19 growth rate and travel distance decay rate and dwell time at home change rate was -0.586 (95% CI: -0.742 ~ -0.370) and 0.526 (95% CI: 0.293 ~ 0.700), respectively. Increases in state-specific doubling time of total cases ranged from 1.04 ~ 6.86 days to 3.66 ~ 30.29 days after social distancing orders were put in place, consistent with mechanistic epidemic prediction models. Social distancing mandates reduce the spread of COVID-19 when they are followed.

title: The Severe Acute Respiratory Syndrome Coronavirus-2 (SARS CoV-2) in Dentistry. Management of Biological Risk in Dental Practice

text: The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a novel coronavirus first identified in Wuhan, China, and the etiological agent of Coronavirus Disease-2019 (COVID-19). This infection spreads mainly through direct contact with Flügge micro droplets or core droplets that remain suspended as aerosol. Moreover, it has been reported that infected subjects, both with and without clinical signs of COVID-19, can transmit the virus. Since the infection typically enters through mouth, nose, and eyes, dentistry is one of the medical practices at highest risk of infection due to the frequent production of aerosol and the constant presence of saliva. The World Health Organization (WHO) has suggested that only emergency/urgent procedures should be performed during the coronavirus outbreak. Considering the virus' route of transmission, a specific protocol should be applied to reduce the risk of infection in addition to measures that prevent the spread of infection from a patient to another person or medical tools and equipment (cross-infection). This protocol should be implemented by modifying both patient management and clinical practice, introducing particular devices and organizational practices. This paper aims to discuss and suggest the most appropriate procedures in every aspect of dental practice to reduce infection risk.


title: COVID-19: Challenges and Lessons Learned from Early Career Investigators

text: In March 2020, the United States experienced an unprecedented event that suddenly demanded that researchers cease all nonessential activities to mitigate the rapid spread of the SARS-CoV2. Within the research community, the impact of this cessation on early career investigators was significant, in part because the support systems (i.e., mentors and institutions) that early career investigators typically rely on were also significantly impacted. This article presents the stories of the impact of COVID-19 on early career investigators within the NIH Building Interdisciplinary Research Careers in Women's Health and Women's Reproductive Health Research K12 career development programs. We discuss the common challenges that we faced across our respective fields ranging from basic to clinical to epidemiological women's health research, including the impact it had on our career trajectories. In addition, we share lessons learned in an effort to strengthen our research workforce and increase our resiliency during this and future challenges.

title: [Countermeasures and treatment for aortic acute syndrome with novel coronavirus pneumonia]

text: The novel coronavirus pneumonia (NCP) has cost a great loss to the health and economic property of Chines people. Under such a special circumstance, how to deal with such patients with acute aortic syndrome has become a serious challenge. Rapid diagnosis of concomitant NCP, safe and effective transportation, implementation of the interventional procedure, protection of vascular surgical team and postoperative management and follow-up of such patients have become urgent problems for us. Combined with the latest novel government documents, the literature and the experiences from Wuhan, we answered the above questions briefly and plainly. It also hopes to inspire the national vascular surgeons to manage critical emergencies in vascular surgery and even routine vascular diseases with NCP, as a final point to limit the severe epidemic situation, and minimize the damage of NCP.

title: Metabolic syndrome and its components in adult hypopituitary patients

text: PURPOSE: To evaluate the prevalence of metabolic syndrome (MetS) and its components in adult hypopituitary patients. PATIENTS AND METHODS: Retrospective, cross-sectional analysis of a cohort of hypopituitary adult patients followed in a single reference center for pituitary diseases. MetS was defined by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. Patients with 18 years or older, presenting two or more anterior pituitary deficiencies associated or not with diabetes insipidus (DI), were included, while patients with hypopituitarism due to Acromegaly or Cushing's disease were excluded. RESULTS: We studied 99 hypopituitary patients (52 males, mean age 50.1 ± 16.3 years, mean age at diagnosis 33.7 ± 17.6 years) who have been followed for a mean time of 15.9 ± 10.1 years. Hypothalamic-pituitary tumors and non-tumoral etiologies were observed in 53.4% and 46.6% of the cases, respectively. FSH/LH, GH, TSH, ACTH deficiency and DI was present in 99%, 98.6%, 96%, 81.8%, and 23.2%, respectively. The prevalence of MetS was 39.4% and was significantly higher in patients older than 50 years (p = 0.02), overweight/obese (p < 0.001), with hypopituitarism diagnosed in adult life (p = 0.02), who did not replace GH (p = 0.004) and in smokers (p = 0.007). In the logistic regression model, body mass index (BMI) and GH replacement were significantly associated with the presence of MetS. Reduced HDL cholesterol was the most prevalent component of MetS in hypopituitary patients. CONCLUSIONS: MetS is a common finding in adult hypopituitary patients, which is mainly influenced by increased BMI and untreated GH deficiency.

title: Can post-exposure prophylaxis for COVID-19 be considered as an outbreak response strategy in long-term care hospitals?

text: In the context of the ongoing global outbreak of coronavirus disease 2019 (COVID-19), management of exposure events is a concern. Long-term care hospitals (LTCHs) are particularly vulnerable to cluster outbreaks because facilities for patient isolation and healthcare personnel to care for these patients in isolation are difficult to arrange in a large outbreak situation. Although several drugs have been proposed as treatment options, there are no data on the effectiveness and safety of post-exposure prophylaxis (PEP) for COVID-19. After a large COVID-19 exposure event in an LTCH in Korea, PEP using hydroxychloroquine (HCQ) was administered to 211 individuals, including 189 patients and 22 careworkers, whose baseline polymerase chain reaction (PCR) tests for COVID-19 were negative. PEP was completed in 184 (97.4%) patients and 21 (95.5%) careworkers without serious adverse events. At the end of 14 days of quarantine, all follow-up PCR tests were negative. Based on our experience, further clinical studies are recommended for COVID-19 PEP.


title: A Peptide-Based Magnetic Chemiluminescence Enzyme Immunoassay for Serological Diagnosis of Coronavirus Disease 2019

text: BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel ß-coronavirus, causes severe pneumonia and has spread throughout the globe rapidly. The disease associated with SARS-CoV-2 infection is named coronavirus disease 2019 (COVID-19). To date, real-time reverse-transcription polymerase chain reaction (RT-PCR) is the only test able to confirm this infection. However, the accuracy of RT-PCR depends on several factors; variations in these factors might significantly lower the sensitivity of detection. METHODS: In this study, we developed a peptide-based luminescent immunoassay that detected immunoglobulin (Ig)G and IgM. The assay cutoff value was determined by evaluating the sera from healthy and infected patients for pathogens other than SARS-CoV-2. RESULTS: To evaluate assay performance, we detected IgG and IgM in the sera from confirmed patients. The positive rate of IgG and IgM was 71.4% and 57.2%, respectively. CONCLUSIONS: Therefore, combining our immunoassay with real-time RT-PCR might enhance the diagnostic accuracy of COVID-19.


title: Estimated and measured core temperature responses to high-intensity warm weather military training: implications for exertional heat illness risk assessment

text: OBJECTIVE: Humans avoid overheating through physiological and behavioral mechanisms. However, elite athletes, industrial workers, and military personnel, driven by the tasks at hand, may choose to continue working and face an increased risk of exertional heat illness (EHI). We wanted to examine the efficacy of a new core temperature (Tcr) estimation algorithm in assessing EHI risk. APPROACH: Physiological responses of 21 male Royal Marines recruits (age 21±2 y, height 1.79±0.05 m, weight 80.5±7.2 kg) were collected during a physically-demanding criterion road march (14.5 km in 90 min with a 9.6 kg load; air temperature 16°C, relative humidity ≥ 84%). Measured Tcr (thermometer pill) and estimated Tcr (ECTempTM Tcr-est) were compared. MAIN RESULTS: Measured Tcr either increased to an asymptote Tcr < 39.5°C (WARM; n=11), or progressively increased to Tcr > 40.0°C (HOT; n=10). In the HOT group, Tcr-est reflected measured Tcr up to Tcr = 40.0°C (Bias = -0.10 ± 0.37°C, root mean square error = 0.37 ± 0.13°C). In the WARM group, Tcr-est overestimated Tcr (Bias = 0.34 ± 0.40°C) and was higher from mid-point to end. A logistic regression (Skin temperature approximate entropy and mean heart rate) was able to predict group membership (95% accuracy) at 20 minutes, allowing a WARM group ECTemp(TM) correction factor (corrected Bias=0.00 ± 0.29°C). SIGNIFICANCE: The Tcr-est successfully tracked Tcr in the HOT group with high risk of exertional heat illness (EHI) (40% incidence). Skin temperature complexity shows promise as a non-invasive means of insight into the state of thermoregulatory control mechanisms.


title: Ig-like ACE2 protein therapeutics: A revival in development during the COVID-19 pandemic

text: While the potential therapeutic utility of angiotensin-converting enzyme 2 (ACE2) is well established, the clinical development of ACE2 drugs has been limited, likely due in part to the short half-life of the protein. In contrast, Ig-like ACE2 fusion proteins have exhibited greatly extended plasma half-life in vivo, and they have been shown to have a potent neutralization effect against SARS-CoV-2. Clinical investigation of Ig-like ACE2 fusion proteins as COVID-19 interventions is thus warranted.


title: Turkey's response to COVID-19 in terms of mental health

text: Coronavirus disease (also known as COVID-19) continues to spread throughout the world. In Turkey, which has a strong health system, most hospitals have been turned into pandemic hospitals, elective procedures have been postponed, and doctors have been reassigned to treat COVID-19. Efforts to limit spread of COVID-19 have been effective in reducing the spread of COVID-19. Behind this success was not only the intrinsic strength of the health system but also the strict changes in everyday life wrought by the crisis. It is an inescapable fact that these new measures, such as the imposition of curfew and lockdown, have had a significant effect on the mental health of the general population. Anxiety caused by COVID-19 has spread to the mental state of everyone. Although coronavirus-related diseases will end soon, it is predicted that serious psychiatric disorders will be a lasting consequence of the pandemic. Despite the many negatives brought by COVID-19, it has led to a positive unity between the public and healthcare professionals, and in spite of significant risks to their own health, healthcare workers have risen to the challenge of COVID-19.


title: Colorblind Algorithms: Racism in the Era of COVID-19

text: This commentary offers a critique of the recent policy document issued by White et al. (2020) to guide critical care resource (e.g. ventilators) allocation during public health emergencies such as COVID-19. We argue that, if disseminated widely, this criteria would result in a racially inequitable resource distribution in the current COVID-19 crisis. We link the White et al. (2020) resource distribution protocol to other "colorblind" healthcare algorithms that have relied on seemingly objective but fundamentally biased data, thereby reinforcing and exacerbating pre-existing racial health disparities. We suggest a health equity framework to ensure unbiased distribution of critical care resources during COVID-19 and in general practice.

title: Chaos game representation dataset of SARS-CoV-2 genome

text: As of April 16, 2020, the novel coronavirus disease (called COVID-19) spread to more than 185 countries/regions with more than 142,000 deaths and more than 2,000,000 confirmed cases. In the bioinformatics area, one of the crucial points is the analysis of the virus nucleotide sequences using approaches such as data stream, digital signal processing, and machine learning techniques and algorithms. However, to make feasible this approach, it is necessary to transform the nucleotide sequences string to numerical values representation. Thus, the dataset provides a chaos game representation (CGR) of SARS-CoV-2 virus nucleotide sequences. The dataset provides the CGR of 100 instances of SARS-CoV-2 virus, 11540 instances of other viruses from the Virus-Host DB dataset, and three instances of Riboviria viruses from NCBI (Betacoronavirus RaTG13, bat-SL-CoVZC45, and bat-SL-CoVZXC21).

title: Emergence of deadly severe acute respiratory syndrome coronavirus-2 during 2019-2020

text: Wuhan, the city in Hubei province in China is in the focus of global community due to the outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), formerly known as 2019-nCoV. The virus emerged in humans from Wuhan seafood market probably via zoonotic transmission. Within a few days the virus spread its tentacles rapidly to neighboring cities in China and to different geographical regions through travelers and to some extent by human to human transmission leading to significant disease burden globally. More than 2,00,000 people (including more than 8000 deaths) have been infected with this respiratory illness across 167 countries and territories worldwide leading to a pandemic. The present review provides an outline about emergence and spread of SARS-CoV-2 from Wuhan, China in 2019-2020. We have also provided information about the classification, genome, proteins, clinical presentation of COVID-19, type of clinical specimens to be collected and diagnostic methods adopted to identify the respiratory illness. In addition we have also provided information about transmission dynamics, prevention measures and treatment options that are available at the present. Subsequently, we have given a comprehensive overview of the spread of this infection from China to the other parts of the globe. Management of the ongoing outbreak of SARS-CoV-2 encompassing surveillance, clinical, immunological, genetic and evolutionary investigations are likely to provide the desired results. Joint efforts of global scientific community are needed at this hour in terms of enhancement of research on development of accurate diagnostics, antiviral therapeutics and finally into formation of an effective vaccine against the emerging novel coronavirus.


title: COVID-19 and its implications for thrombosis and anticoagulation

text: Severe acute respiratory syndrome coronavirus 2, coronavirus disease 2019 (COVID-19)-induced infection can be associated with a coagulopathy, findings consistent with infection-induced inflammatory changes as observed in patients with disseminated intravascular coagulopathy (DIC). The lack of prior immunity to COVID-19 has resulted in large numbers of infected patients across the globe and uncertainty regarding management of the complications that arise in the course of this viral illness. The lungs are the target organ for COVID-19; patients develop acute lung injury that can progress to respiratory failure, although multiorgan failure can also occur. The initial coagulopathy of COVID-19 presents with prominent elevation of D-dimer and fibrin/fibrinogen-degradation products, whereas abnormalities in prothrombin time, partial thromboplastin time, and platelet counts are relatively uncommon in initial presentations. Coagulation test screening, including the measurement of D-dimer and fibrinogen levels, is suggested. COVID-19-associated coagulopathy should be managed as it would be for any critically ill patient, following the established practice of using thromboembolic prophylaxis for critically ill hospitalized patients, and standard supportive care measures for those with sepsis-induced coagulopathy or DIC. Although D-dimer, sepsis physiology, and consumptive coagulopathy are indicators of mortality, current data do not suggest the use of full-intensity anticoagulation doses unless otherwise clinically indicated. Even though there is an associated coagulopathy with COVID-19, bleeding manifestations, even in those with DIC, have not been reported. If bleeding does occur, standard guidelines for the management of DIC and bleeding should be followed.


title: Enhancing Patch-Based Methods with Inter-frame Connectivity for Denoising Multi-frame Images

text: The 3D block matching (BM3D) method is among the state-of-art methods for denoising images corrupted with additive white Gaussian noise. With the help of a novel inter-frame connectivity strategy, we propose an extension of the BM3D method for the scenario where we have multiple images of the same scene. Our proposed extension outperforms all the existing trivial and non-trivial extensions of patch-based denoising methods for multi-frame images. We can achieve a quality difference of as high as 28% over the next best method without using any additional parameters. Our method can also be easily generalised to other similar existing patch-based methods.


title: An overview of the genetic variations of the SARS-CoV-2 genomes isolated in Southeast Asian countries

text: 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.


title: The American Heart Association COVID-19 CVD Registry powered by Get With The Guidelines®

text: Background: In response to the public health emergency created by the COVID-19 pandemic, American Heart Association volunteers and staff aimed to rapidly develop and launch a resource for the medical and research community to expedite scientific advancement through shared learning, quality improvement, and research. In less than 4 weeks after it was first announced on April 3, 2020, AHA's COVID-19 CVD Registry powered by Get With The Guidelines® (GWTG) received its first clinical records. Methods and Results: Participating hospitals are enrolling consecutive hospitalized patients with active COVID-19 disease, regardless of CVD status. This hospital quality improvement program will allow participating hospitals and health systems to evaluate patient-level data including mortality rates, intensive care unit (ICU) bed days, and ventilator days from individual review of electronic medical records of sequential adult patients with active COVID-19 infection. Participating sites can leverage these data for onsite, rapid quality improvement and benchmarking versus other institutions. After 9 weeks, more than 130 sites have enrolled in the program and more than 4,000 records have been abstracted in the national dataset. Additionally, the aggregate dataset will be a valuable data resource for the medical research community. Conclusions: The AHA COVID-19 CVD Registry will support greater understanding of the impact of COVID-19 on cardiovascular disease and will inform best practices for evaluation and management of patients with COVID-19.


title: Deployment of convalescent plasma for the prevention and treatment of COVID-19

text: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of coronavirus disease 2019 (COVID-19), has spurred a global health crisis. To date, there are no proven options for prophylaxis for those who have been exposed to SARS-CoV-2, nor therapy for those who develop COVID-19. Immune (i.e., "convalescent") plasma refers to plasma that is collected from individuals following resolution of infection and development of antibodies. Passive antibody administration through transfusion of convalescent plasma may offer the only short-term strategy for conferring immediate immunity to susceptible individuals. There are numerous examples in which convalescent plasma has been used successfully as postexposure prophylaxis and/or treatment of infectious diseases, including other outbreaks of coronaviruses (e.g., SARS-1, Middle East respiratory syndrome [MERS]). Convalescent plasma has also been used in the COVID-19 pandemic; limited data from China suggest clinical benefit, including radiological resolution, reduction in viral loads, and improved survival. Globally, blood centers have robust infrastructure for undertaking collections and constructing inventories of convalescent plasma to meet the growing demand. Nonetheless, there are nuanced challenges, both regulatory and logistical, spanning donor eligibility, donor recruitment, collections, and transfusion itself. Data from rigorously controlled clinical trials of convalescent plasma are also few, underscoring the need to evaluate its use objectively for a range of indications (e.g., prevention vs. treatment) and patient populations (e.g., age, comorbid disease). We provide an overview of convalescent plasma, including evidence of benefit, regulatory considerations, logistical work flow, and proposed clinical trials, as scale-up is brought underway to mobilize this critical resource.
