title: [Investigation on demands for antenatal care services among 2 002 pregnant women during the epidemic of COVID-19 in Shanghai]

text: Objective: To identify problems and demands for antenatal care (ANC) among pregnant women in different trimesters of pregnancy in Shanghai for optimizing ANC service during the epidemic of COVID-19. Method: s Organized by maternal and child health care institute in the 16 districts of Shanghai, a cross sectional study was conducted among pregnant women who came to pregnancy registration in the community health centers or attended ANC in midwifery hospitals from February 7 to February 12, 2020. Consented participating women completed a semi-structured online questionnaire voluntarily. Data was analyzed using frequency,chi-square test and scoring. Result: s A total of 2 002 valid questionnaires were collected from 183 community health centers and 67 midwifery hospitals. About 94.6%(1 894/2 002) of the pregnant women worried about being infected during the COVID-19 epidemic, and 14.7% (294/2 002) demanded for psychological consultation. Time-lapse appointments for ANC were requested by 87.7% (1 756/2 002) of the participants for avoiding presenting themselves in people-density places. Compared with other pregnancy trimesters, pregnant women in the second trimester were more willing to reduce the frequency of ANC (35.2% versus 39.5% versus 48.1%, P<0.01). Compared with multiparas, primiparas were more willing to have online consultation and guidance (49.2% versus 63.8%, P<0.01). Regarding the needs for health knowledge on COVID-19, personal protection against 2019 novel coronavirus (2019-nCoV) was the most concerned for pregnant women, and 71.0% (1 421/2 002) of them preferred to obtain knowledge through health applications, official Weibo and WeChat. Conclusions: Pregnant women in Shanghai critically concern about the risk of 2019-nCoV infections, and highly demand knowledge and measures on prevention and protection from COVID-19. They ask for having time-lapse appointments for ANC and online access to health information and services. Maternal and child care institutes should understand the demands of pregnant women, optimize the means of ANC service, and provide tailored and accessible health education and service for the safety of mother and child.

title: The novel coronavirus (COVID-2019) outbreak: Amplification of public health consequences by media exposure

text: The 2019 novel coronavirus (COVID-2019) has led to a serious outbreak of often severe respiratory disease, which originated in China and has quickly become a global pandemic, with far-reaching consequences that are unprecedented in the modern era. As public health officials seek to contain the virus and mitigate the deleterious effects on worldwide population health, a related threat has emerged: global media exposure to the crisis. We review research suggesting that repeated media exposure to community crisis can lead to increased anxiety, heightened stress responses that can lead to downstream effects on health, and misplaced health-protective and help-seeking behaviors that can overburden health care facilities and tax available resources. We draw from work on previous public health crises (i.e., Ebola and H1N1 outbreaks) and other collective trauma (e.g., terrorist attacks) where media coverage of events had unintended consequences for those at relatively low risk for direct exposure, leading to potentially severe public health repercussions. We conclude with recommendations for individuals, researchers, and public health officials with respect to receiving and providing effective communications during a public health crisis.

title: The impact of the coronavirus disease 2019 pandemic on the utilisation of emergency urological services

text: OBJECTIVES: To compare the number of patients attending the Urology Emergency Department (ED) of the Centro Hospitalar Universitário do Porto (CHUP), as well as their demographic characteristics, the reasons for admission, the clinical severity under the Manchester triage system (MTS), and the need for emergency surgery or hospitalisation, during the coronavirus disease 2019 (COVID-19) pandemic and the equivalent period in 2019. PATIENTS AND METHODS: Data were collected from patients attending the Urology ED of the CHUP over 3 weeks, from 11 March to 1 April 2020, and from the same period in the previous year (from 11 March to 1 April 2019). RESULTS: During the pandemic, 46.4% fewer patients visited our urological ED (122 vs 263). There was no significant difference in the mean age or the number of old patients (aged ≥65 years) between the two periods. However, significantly fewer female patients sought emergency urological services during the COVID-19 pandemic period (32.7% vs 14.8%, P < 0.05). No significant differences were noted between different clinical severity groups under the MTS. In 2019, significantly less patients required hospitalisation. The most common reasons for admission, during both periods, were haematuria, renal colic and urinary tract infections. The authors recognise that the study has several limitations, namely, those inherent to its retrospective nature. CONCLUSION: COVID-19 significantly influenced people's urological care-seeking behaviour. Understanding the present situation is helpful for predicting future urological needs. Based on the results of this study, we have reason to speculate that people's requirements for urological services might grow explosively in the post-COVID-19 period. There should be further studies about the real state of long-term urological services and the consequences that this pandemic may have in terms of morbimortality not directly related to the severe acute respiratory syndrome coronavirus 2.


title: Therapeutic Temperature Modulation for a Critically Ill Patient with COVID-19

text: We report a rapidly deteriorating coronavirus disease 2019 (COVID-19) patient, a-58-year-old woman, with severe acute respiratory distress syndrome and shock with hyperpyrexia up to 41.8°C, probably due to the cytokine storm syndrome. Considering extracorporeal membrane oxygenation (ECMO) as the last resort, we applied therapeutic temperature modulation for management of hyperpyrexia. The patient demonstrated rapid improvement in oxygenation and shock after achieving normothermia, and fully recovered from COVID-19 three weeks later. Therapeutic temperature modulation may have successfully offloaded the failing cardiorespiratory system from metabolic cost and hyperinflammation induced by hyperpyrexia. The therapeutic temperature modulation can safely be applied in a specific group of patients with cytokine storm syndrome and hyperpyrexia, which may reduce the number of patients requiring ECMO in the global medical resource shortage.


title: Sars-cov-2 host entry and replication inhibitors from Indian ginseng: an in-silico approach

text: COVID-19 has ravaged the world and is the greatest of pandemics in modern human history, in the absence of treatment or vaccine, the mortality and morbidity rates are very high. The present investigation identifies potential leads from the plant Withania somnifera (Indian ginseng), a well-known antiviral, immunomodulatory, anti-inflammatory and a potent antioxidant plant, using molecular docking and dynamics studies. Two different protein targets of SARS-CoV-2 namely NSP15 endoribonuclease and receptor binding domain of prefusion spike protein from SARS-CoV-2 were targeted. Molecular docking studies suggested Withanoside X and Quercetin glucoside from W. somnifera have favorable interactions at the binding site of selected proteins, that is, 6W01 and 6M0J. The top-ranked phytochemicals from docking studies, subjected to 100 ns molecular dynamics (MD) suggested Withanoside X with the highest binding free energy (ΔGbind = -89.42 kcal/mol) as the most promising inhibitor. During MD studies, the molecule optimizes its conformation for better fitting with the receptor active site justifying the high binding affinity. Based on proven therapeutic, that is, immunomodulatory, antioxidant and anti-inflammatory roles and plausible potential against n-CoV-2 proteins, Indian ginseng could be one of the alternatives as an antiviral agent in the treatment of COVID 19.

title: Temporal Correlation Between Neurological and Gastrointestinal Symptoms of SARS-CoV-2

text: Severe Acute Respiratory Syndrome Coronavirus-2 (SAR-CoV-2) has been shown to invade brain tissue. Based on the evolutionary similarity with SARS-CoV, researchers propose that SARS-CoV-2 can invade the olfactory bulb and gastrointestinal (GI) system through angiotensin-converting enzyme 2. However, how SARS-CoV-2 causes neurological or GI symptoms is not clear. Many suggested intestinal and neural inflammations, caused by viral invasion, as the most likely reason for the GI and neurological symptoms; however, the patients with coronavirus disease 2019 (COVID-19) without neurological or GI symptoms indicate that this is not the case. The gut-brain axis could explain the reason for why some with COVID-19 do not have these symptoms. COVID-19 patients mostly show respiratory distress first, then diarrhea, anorexia, stroke, or loss of consciousness comes into view. Obviously, GI invasion is a mechanical process that begins with oral invasion and, therefore, most probably exists before the brain invasion, as indicated in case reports. However, when the GI tract is invaded, the virus may enter the central nervous system through vascular and lymphatic systems or the vagal nerve. SARS-CoV-2 can infect leukocytes and migrate with them into the brain, or the viral particles can be directly transported across the blood-brain barrier to the brain. Also, more recent research has revealed that SARS-CoV-2 can invade the peripheral lymphatic vessels connecting with the glymphatic system of the brain. The temporal correlation between neurological and gastrointestinal symptoms suggests the lymph vessels around the GI tract, the vascular system, or the gut-brain axis (enteric nervous system) as the most likely entry route for SARS-CoV-2 to the brain.

title: Bacterial and fungal coinfection among hospitalised patients with COVID-19: A retrospective cohort study in a UK secondary care setting

text: OBJECTIVES: We investigate the incidence of bacterial and fungal co-infection of hospitalised patients with confirmed SARS-CoV-2 in this retrospective observational study across two London hospitals during the first UK wave of COVID-19. METHODS: A retrospective case-series of hospitalised patients with confirmed SARS-CoV-2 by PCR was analysed across two acute NHS hospitals (February 20-April 20; each isolate reviewed independently in parallel). This was contrasted to a control group of influenza positive patients admitted during 2019/20 flu season. Patient demographics, microbiology, and clinical outcomes were analysed. RESULTS: 836 patients with confirmed SARS-CoV-2 were included; 27/836(3.2%) had early confirmed bacterial isolates identified (0-5 days post-admission) rising to 51/836(6.1%) throughout admission. Blood cultures, respiratory samples, pneumococcal or legionella urinary antigens, and respiratory viral PCR panels were obtained from 643(77%), 112(13%), 249(30%), 246(29%) and 250(30%) COVID-19 patients, respectively. A positive blood culture was identified in 60(7.1%) patients, of which 39/60 were classified as contaminants. Bacteraemia secondary to respiratory infection was confirmed in two cases (1 community-acquired K. pneumoniae and 1 ventilator-associated E. cloacae). Line-related bacteraemia was identified in six patients (3 candida, 2 Enterococcus spp. and 1 Pseudomonas aeruginosa). All other community acquired bacteraemias(16) were attributed to non-respiratory infection. Zero concomitant pneumococcal, legionella or influenza infection was detected. A low yield of positive respiratory cultures was identified; S. aureus the most common respiratory pathogen isolated in community-acquired coinfection (4/24;16.7%) with pseudomonas and yeast identified in late-onset infection. Invasive fungal infections (n=3) were attributed to line related infections. Comparable rates of positive co-infection were identified in the control group of confirmed influenza infection; clinically relevant bacteraemias (2/141;1.4%), respiratory cultures (10/38;26.1%) and pneumococcal-positive antigens (1/19;5.2%) were low. CONCLUSION: We find a low frequency of bacterial co-infection in early COVID hospital presentation, and no evidence of concomitant fungal infection, at least in the early phase of COVID-19.

title: Association of the global activity limitation indicator with specific measures of disability in adults aged below 65

text: BACKGROUND: health measures as the global activity limitation indicator (GALI) or self-rated health (SRH) allow to quantify and monitor the health of the population. The GALI is widely used in the European Union; however, evidence of its construct validity is still limited. We examine whether the GALI reflects disability in specific living contexts such as self-care, domestic life and work activity, whether it does so consistently across gender and age and its added value concerning SRH. METHODS: We used the subsample of adults aged 16-64 years (N = 15 934) from the 2009 European Health Interview Survey in Spain and analyzed the data with logistic regression models using the GALI and SRH as response variables. RESULTS: The GALI was strongly and significantly associated with the three measures of disability: self-care (OR = 22.8, 95% CI: 15.9-32.7), domestic life (OR = 16.3, 95% CI: 13.6-19.5) and work activity (e.g. impossibility to work: OR = 41.9, 95% CI: 30.3-57.8; prolonged sick leave: OR = 10.7, 95% CI: 9-12.7). There were significant interactions with age on all three disability measures and with the gender on one (domestic life), although they were small. SRH was also strongly associated with all three disability measures, but to a lesser extent than the GALI. CONCLUSIONS: The GALI reflects well and better than SRH, disability in self-care, domestic life and work activity. It is unknown whether the GALI performs equally in other living contexts such as social relations and community life.

title: Virus detections among patients with severe acute respiratory illness, Northern Vietnam

text: Severe acute respiratory illness (SARI) is a major cause of death and morbidity in low- and middle-income countries, however, the etiologic agents are often undetermined due to the lack of molecular diagnostics in hospitals and clinics. To examine evidence for select viral infections among patients with SARI in northern Vietnam, we studied 348 nasopharyngeal samples from military and civilian patients admitted to 4 hospitals in the greater Hanoi area from 2017-2019. Initial screening for human respiratory viral pathogens was performed in Hanoi, Vietnam at the National Institute of Hygiene and Epidemiology (NIHE) or the Military Institute of Preventative Medicine (MIPM), and an aliquot was shipped to Duke-NUS Medical School in Singapore for validation. Patient demographics were recorded and used to epidemiologically describe the infections. Among military and civilian cases of SARI, 184 (52.9%) tested positive for one or more respiratory viruses. Influenza A virus was the most prevalent virus detected (64.7%), followed by influenza B virus (29.3%), enterovirus (3.8%), adenovirus (1.1%), and coronavirus (1.1%). Risk factor analyses demonstrated an increased risk of influenza A virus detection among military hospital patients (adjusted OR, 2.0; 95% CI, 1.2-3.2), and an increased risk of influenza B virus detection among patients enrolled in year 2017 (adjusted OR, 7.9; 95% CI, 2.7-22.9). As influenza A and B viruses were commonly associated with SARI and are treatable, SARI patients entering these hospitals would benefit if the hospitals were able to adapt onsite molecular diagnostics.

title: Burden of acute respiratory disease of epidemic and pandemic potential in the WHO Eastern Mediterranean Region: A literature review

text: There are gaps in the knowledge about the burden of severe respiratory disease in the Eastern Mediterranean Region (EMR). This literature review was therefore conducted to describe the burden of epidemic-and pandemic-prone acute respiratory infections (ARI) in the Region which may help in the development of evidence-based disease prevention and control policies. Relevant published and unpublished reports were identified from searches of various databases; 83 documents fulfilled the search criteria. The infections identified included: ARI, avian influenza A(H5N1), influenza A(H1N1)pdm09 and Middle East respiratory syndrome coronavirus (MERS-CoV) infection. Pneumonia and ARIs were leading causes of disease and death in the Region. Influenza A(H1N1) was an important cause of morbidity during the 2009 pandemic. This review provides a descriptive summary of the burden of acute respiratory diseases in the Region, but there still remains a lack of necessary data. On observe des lacunes en matière de connaissances concernant la charge des maladies respiratoires sévères dans la Région de la Méditerranée orientale. La présente analyse documentaire détaille la charge des infections respiratoires aiguës (IRA) à potentiel épidémique et pandémique dans la Région, ce qui peut aider à l'élaboration de politiques et programmes de prévention et de lutte contre les maladies reposant sur des données factuelles. Des articles pertinents publiés et non publiés ont été identifiés grâce à des recherches dans différentes bases de données ; 83 documents satisfaisaient à nos critères de recherche. Les infections identifiées comprenaient les infections respiratoires aiguës (IRA), la grippe aviaire A(H5N1), la grippe A(H1N1)pdm09 et l'infection par le coronavirus du syndrome respiratoire du Moyen-Orient (MERS-CoV). La pneumonie et les IRA constituaient les principales causes de morbidité et de mortalité dans la Région. La grippe A(H1N1) était une cause importante de morbidité durant la pandémie de 2009. Cette analyse fournit un résumé descriptif de la charge des maladies respiratoires aiguës dans la Région mais il existe toujours une lacune concernant les donneés nécessaires à cet égard.

title: Surgical Oncologists and the COVID-19 Pandemic: Guiding Cancer Patients Effectively through Turbulence and Change

text: BACKGROUND: The COVID-19 pandemic has posed extraordinary demands from patients, providers, and health care systems. Despite this, surgical oncologists must maintain focus on providing high-quality, empathetic care for the almost 2 million patients nationally who will be diagnosed with operable cancer this year. The focus of hospitals is transitioning from initial COVID-19 preparedness activities to a more sustained approach to cancer care. METHODS: Editorial Board members provided observations of the implications of the pandemic on providing care to surgical oncology patients. RESULTS: Strategies are presented that have allowed institutions to successfully prepare for cancer care during COVID-19, as well as other strategies that will help hospitals and surgical oncologists manage anticipated challenges in the near term. Perspectives are provided on: (1) maintaining a safe environment for surgical oncology care; (2) redirecting the multidisciplinary model to guide surgical decisions; (3) harnessing telemedicine to accommodate requisite physical distancing; (4) understanding interactions between SARS CoV-2 and cancer therapy; (5) considering the ethical impact of professional guidelines for surgery prioritization; and (6) advocating for our patients who require oncologic surgery in the midst of the COVID-19 pandemic. CONCLUSIONS: Until an effective vaccine becomes available for widespread use, it is imperative that surgical oncologists remain focused on providing optimal care for our cancer patients while managing the demands that the COVID-19 pandemic will continue to impose on all of us.

title: On a Comprehensive Model of the Novel Coronavirus (COVID-19) Under Mittag-Leffler Derivative

text: The major purpose of the presented study is to analyze and find the solution for the model of nonlinear fractional differential equations (FDEs) describing the deadly and most parlous virus so-called coronavirus (COVID-19). The mathematical model depending of fourteen nonlinear FDEs is presented and the corresponding numerical results are studied by applying the fractional Adams Bashforth (AB) method. Moreover, a recently introduced fractional nonlocal operator known as Atangana-Baleanu (AB) is applied in order to realize more effectively. For the current results, the fixed point theorems of Krasnoselskii and Banach are hired to present the existence, uniqueness as well as stability of the model. For numerical simulations, the behavior of the approximate solution is presented in terms of graphs through various fractional orders. Finally, a brief discussion on conclusion about the simulation is given to describe how the transmission dynamics of infection take place in society.

text: OBJECTIVE. Since the outbreak of the novel coronavirus pulmonary illness coronavirus disease 2019 (COVID-19) in China, more than 79,000 people have contracted the virus worldwide. The virus is rapidly spreading with human-to-human transmission despite imposed precautions. Because similar pulmonary syndromes have been reported from other strains of the coronavirus family, our aim is to review the lessons from imaging studies obtained during severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) outbreaks. CONCLUSION. The review of experiences with the MERS and SARS outbreaks will help us better understand the role of the radiologist in combating the outbreak of COVID-19. The known imaging manifestations of the novel coronavirus and the possible unknowns will also be discussed.

title: Does 'Fear of COVID-19' trigger future career anxiety? An empirical investigation considering depression from COVID-19 as a mediator

text: BACKGROUND: Due to the outbreak of COVID-19, the mental health of the people all around the world is severely disrupted. AIM: The purpose of this study is to identify whether 'Fear of COVID-19' impacted on future workforces' career anxiety at the first place and whether depression from COVID-19 has any indirect effect on 'Fear of COVID-19' and future workforces' career anxiety. METHOD: Based on three different scales related to 'Fear of COVID-19', depression and career anxiety, a structured questionnaire was developed and the survey data was collected for this study. RESULTS: The empirical result of the study reveals that, due to the outbreak of COVID-19 fear, the future workforce is getting anxious about their future career. Again, depression from COVID-19, caused by 'Fear of COVID-19', as a mediator, has a significant indirect impact on the relationship between 'Fear of COVID-19' and future career anxiety, resulting in a full mediation. This means, due to the outbreak of 'Fear of COVID-19' people are becoming depressed and anxious about their future career which is creating a long-term negative effect on human psychology. CONCLUSION: These research findings will be a major tool for the policymakers, as well as the human resource planning professionals, to sketch plans after COVID-19 pandemic. This study is a novel work combining the concepts of fear and depression with career anxiety in a pandemic situation like COVID-19, and also assists future researchers in many folds.


title: Mathematical assessment of the impact of non-pharmaceutical interventions on curtailing the 2019 novel Coronavirus

text: A pandemic of a novel Coronavirus emerged in December of 2019 (COVID-19), causing devastating public health impact across the world. In the absence of a safe and effective vaccine or antivirals, strategies for controlling and mitigating the burden of the pandemic are focused on non-pharmaceutical interventions, such as social-distancing, contact-tracing, quarantine, isolation, and the use of face-masks in public. We develop a new mathematical model for assessing the population-level impact of the aforementioned control and mitigation strategies. Rigorous analysis of the model shows that the disease-free equilibrium is locally-asymptotically stable if a certain epidemiological threshold, known as the reproduction number (denoted by âc), is less than unity. Simulations of the model, using data relevant to COVID-19 transmission dynamics in the US state of New York and the entire US, show that the pandemic burden will peak in mid and late April, respectively. The worst-case scenario projections for cumulative mortality (based on the baseline levels of anti-COVID non-pharmaceutical interventions considered in the study) decrease dramatically by 80% and 64%, respectively, if the strict social-distancing measures implemented are maintained until the end of May or June, 2020. The duration and timing of the relaxation or termination of the strict social-distancing measures are crucially-important in determining the future trajectory of the COVID-19 pandemic. This study shows that early termination of the strict social-distancing measures could trigger a devastating second wave with burden similar to those projected before the onset of the strict social-distancing measures were implemented. The use of efficacious face-masks (such as surgical masks, with estimated efficacy ≥ 70%) in public could lead to the elimination of the pandemic if at least 70% of the residents of New York state use such masks in public consistently (nationwide, a compliance of at least 80% will be required using such masks). The use of low efficacy masks, such as cloth masks (of estimated efficacy less than 30%), could also lead to significant reduction of COVID-19 burden (albeit, they are not able to lead to elimination). Combining low efficacy masks with improved levels of the other anti-COVID-19 intervention strategies can lead to the elimination of the pandemic. This study emphasizes the important role social-distancing plays in curtailing the burden of COVID-19. Increases in the adherence level of social-distancing protocols result in dramatic reduction of the burden of the pandemic, and the timely implementation of social-distancing measures in numerous states of the US may have averted a catastrophic outcome with respect to the burden of COVID-19. Using face-masks in public (including the low efficacy cloth masks) is very useful in minimizing community transmission and burden of COVID-19, provided their coverage level is high. The masks coverage needed to eliminate COVID-19 decreases if the masks-based intervention is combined with the strict social-distancing strategy.

title: Open Tracheostomy for Covid19 Positive Patients: a Method to Minimize Aerosolization and Reduce Risk of Exposure

text: INTRODUCTION: The COVID-19 virus is highly contagious and thus there is a potential of infecting operating staff when operating on these patients. This case series describes a method of performing open tracheostomy for COVID-19 patients while minimizing potential aerosolization of the virus using typically available equipment and supplies. METHODS: This is a case series of 18 patients who were COVID-19 positive and underwent open tracheostomy in the operating room under a negative pressure plastic hood created using readily available equipment and supplies. Patients had to be intubated for at least 14 days, be convalescing from their cytokine storm, and deemed to survive for at least 14 more days. Other indications for tracheostomy were altered mental status, severe deconditioning, respiratory failure and failed extubation attempts. RESULTS: There were 14 men and 4 women with severe SARS-CoV2 infection requiring long-term intubation since March 23 or later. The mean age was 61.7, BMI was 32.6, and the pre-tracheostomy ventilator day was 20.4. The indications for tracheostomy were altered mental status, severe deconditioning and continued respiratory with hypoxia. Failed extubation attempt rate was 16.7% and hemodialysis rate was 38.9%. All patients were hemodynamically stable, without any evidence of accelerating cytokine storm. To date there was one minor bleeding due to postoperative therapeutic anticoagulation. CONCLUSION: This report describes a method of performing open tracheostomy with minimal aerosolization using readily available equipment and supplies in most hospitals.


title: Systemic Capillary Leak Syndrome secondary to Covid-19

text: Systemic capillary leak syndrome is a rare disorder characterized by dysfunctional inflammatory response, endothelial dysfunction, and extravasation of fluid from the vascular space to the interstitial space leading to shock, hemoconcentration, hypoalbuminemia and subsequent organ failure. The condition may be idiopathic or secondary to an underlying cause, which can include viral infections. Here we describe a patient with acute COVID-19 infection who presented with hemoconcentration, shock and hypoalbuminemia. The patient subsequently developed rhabdomyolysis and compartment syndrome of all four extremities requiring fasciotomies. This is the first reported case of systemic capillary leak syndrome associated with COVID-19 infection. This case adds to the evolving spectrum of inflammatory effects associated with this viral infection.


title: Emergent classical universes from initial quantum states in a tomographical description

text: Quantum and classical physical states are represented in a unified way when they are described by symplectic tomography. Therefore this representation allows us to study directly the necessary conditions for a classical universe to emerge from a quantum state. In the previous study on the de Sitter universe this was done by comparing the classical limit of the quantum tomograms with the tomograms resulting from the classical cosmological equations. In this paper we first review these results and extend them to all the de Sitter models. We show further that these tomograms can be obtained directly from transposing the Wheeler-De Witt equation to the tomographic variables. Subsequently, because the classic limits of the quantum tomograms are identified with their asymptotic expressions, we found the necessary conditions to extend the previous results by taking the tomograms of the WKB solutions of the Wheeler-DeWitt equation with a any potential. Furthermore in the previous works we found that the de Sitter models undergo the quantum-to-classical transition when the cosmological constant decays to its present value, we discuss at the end how far we can extend this result to more general models. In the conclusions, after discussing any improvements and developments of the results of this work, we sketch a phenomenological approach from which to extract information about the initial states of the universe.

title: Prevalence and predictive value of hypocalcemia in severe COVID-19 patients

text: BACKGROUND: The aim of this study was to investigate the performance and predictive value of hypocalcemia in severe COVID-19 patients. METHODS: We retrospectively investigated the clinical and laboratory characteristics of severe COVID-19 patients. 107 patients were divided into hypocalcemia group and normal serum calcium group. The clinical and laboratory data were compared between two groups. The discriminative power of hypocalcemia regarding poor outcome were evaluated by receiver operating curves (ROC) analyses. RESULTS: Sixty seven patients (62.6%) had hypocalcemia. In hypocalcemia group, leukocytes, c-reactive protein (CRP), procalcitonin (PCT), Interleukin 6 (IL-6), and D-dimer levels was higher, while lymphocytes and albumin (ALB) levels was lower. No significant difference was identified in gender, age, signs and symptoms, comorbidities and other laboratory indicators. Serum calcium levels were negatively correlated with leukocytes, CRP, PCT, IL-6 and D-dimer, while positively correlated with lymphocytes and ALB. Patients with hypocalcemia more commonly presented poor outcome (47.8% (32/67) vs 25% (10/40), p=0.02). Median serum calcium levels were significantly lower in the patients with poor outcome (2.01(1.97-2.05) vs 2.10(2.03-2.20), p<0.001), and it could predict the prognosis with an area under the ROC curve (AUC) of 0.73(95% confidence interval (CI) 0.63-0.83, p<0.001). CONCLUSIONS: Hypocalcemia commonly occurred in severe COVID-19 patients and it was associated with poor outcome.


title: Composition and divergence of coronavirus spike proteins and host ACE2 receptors predict potential intermediate hosts of SARS-CoV-2

text: From the beginning of 2002 and 2012, severe respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) crossed the species barriers to infect humans, causing thousands of infections and hundreds of deaths, respectively. Currently, a novel coronavirus (SARS-CoV-2), which has become the cause of the outbreak of Coronavirus Disease 2019 (COVID-19), was discovered. Until 18 February 2020, there were 72 533 confirmed COVID-19 cases (including 10 644 severe cases) and 1872 deaths in China. SARS-CoV-2 is spreading among the public and causing substantial burden due to its human-to-human transmission. However, the intermediate host of SARS-CoV-2 is still unclear. Finding the possible intermediate host of SARS-CoV-2 is imperative to prevent further spread of the epidemic. In this study, we used systematic comparison and analysis to predict the interaction between the receptor-binding domain (RBD) of coronavirus spike protein and the host receptor, angiotensin-converting enzyme 2 (ACE2). The interaction between the key amino acids of S protein RBD and ACE2 indicated that, other than pangolins and snakes, as previously suggested, turtles (Chrysemys picta bellii, Chelonia mydas, and Pelodiscus sinensis) may act as the potential intermediate hosts transmitting SARS-CoV-2 to humans.


Infliximab for severe ulcerative colitis and subsequent SARS-CoV-2 pneumonia: a stone for two birds


title: Dynamics of cascades on burstiness-controlled temporal networks

text: Burstiness, the tendency of interaction events to be heterogeneously distributed in time, is critical to information diffusion in physical and social systems. However, an analytical framework capturing the effect of burstiness on generic dynamics is lacking. We develop a master equation formalism to study cascades on temporal networks with burstiness modelled by renewal processes. Supported by numerical and data-driven simulations, we describe the interplay between heterogeneous temporal interactions and models of threshold-driven and epidemic spreading. We find that increasing interevent time variance can both accelerate and decelerate spreading for threshold models, but can only decelerate epidemic spreading. When accounting for the skewness of different interevent time distributions, spreading times collapse onto a universal curve. Our framework uncovers a deep yet subtle connection between generic diffusion mechanisms and underlying temporal network structures that impacts on a broad class of networked phenomena, from spin interactions to epidemic contagion and language dynamics.


title: Review on government action plans to reduce energy consumption in buildings amid COVID-19 pandemic outbreak

text: The corona virus pandemic outbreak in 2019-2020 has almost touched everyone's life and is affecting every sector. The daily routine life has come to a standstill, many sector including businesses, finance, transport and many more critical industries has come to a halt. Only essential sectors like healthcare have been permitted to operate. Many G20 countries-imposed curfew, mandatory stay-in-home orders and lockdown of cities and countries. Among all these close down scenarios and locked down industries, utility companies and energy distribution sector were operational 24/7 round the clock providing uninterrupted power supply for a comfortable lockdown "stay in home". The success of Fighting COVID-19 and shutdowns is highly dependent upon uninterrupted power supply and power consumption by the building residents. This paper reviews the various actions taken by G20 member countries towards electricity consumption while in COVID-19 pandemic outbreak. This research work is an analysis of actions taken by governments under their jurisdictions towards building energy consumers. The outcome of this paper are energy policy recommendations that are based on the different governments responses and actions taken towards energy consumption in buildings.

title: Model based approach for estimating the dosage regimen of indomethacin a potential antiviral treatment of patients infected with SARS CoV-2

text: To face SARS-CoV-2 pandemic various attempts are made to identify potential effective treatments by repurposing available drugs. Among them, indomethacin, an anti-inflammatory drug, was shown to have potent in-vitro antiviral properties on human SARS-CoV-1, canine CCoV, and more recently on human SARS-CoV-2 at low micromolar range. Our objective was to show that indomethacin could be considered as a promising candidate for the treatment of SARS-CoV-2 and to provide criteria for comparing benefits of alternative dosage regimens using a model-based approach. A multi-stage model-based approach was developed to characterize % of recovery and viral load in CCoV-infected dogs, to estimate the PK of indomethacin in dog and human using published data after administration of immediate (IR) and sustained-release (SR) formulations, and to estimate the expected antiviral activity as a function of different assumptions on the effective exposure in human. Different dosage regimens were evaluated for IR formulation (25 mg and 50 mg three-times-a-day, and 25 mg four-times-a-day), and SR formulation (75 mg once and twice-a-day). The best performing dosing regimens were: 50 mg three-times-a-day for the IR formulation, and 75 mg twice-a-day for the SR formulation. The treatment with the SR formulation at the dose of 75 mg twice-a-day is expected to achieve a complete response in three days for the treatment in patients infected by the SARS-CoV-2 coronavirus. These results suggest that indomethacin could be considered as a promising candidate for the treatment of SARS-CoV-2 whose potential therapeutic effect need to be further assessed in a prospective clinical trial.


title: Hyperglycemia enhances pancreatic cancer progression accompanied by elevations in phosphorylated STAT3 and MYC levels

text: Diabetes mellitus is a well-known risk factor for pancreatic cancer. We focused on hyperglycemia, a main feature of diabetes mellitus, and uncovered its effect on precancerous pancreatic intraepithelial neoplasia (PanIN) progression. In vivo induction of hyperglycemia with 100 mg/kg streptozotocin in KrasLSL G12D Pdx1Cre (KP) mice promoted the PanIN formation and progression. Preconditioning with a high- or low-glucose medium for 28 days showed that a high-glucose environment increased cell viability and sphere formation in PANC-1, a Kras-mutant human pancreatic ductal adenocarcinoma cell line, and mPKC1, a Kras-mutant murine pancreatic cancer cell line. In contrast, no changes were observed in BxPC3, a Kras-wild-type human pancreatic cancer cell line. Orthotopic injection of mPKC1 into the pancreatic tails of BL6/J mice showed that cells maintained in high-glucose medium grew into larger tumors than did those maintained in low-glucose medium. Hyperglycemia strengthened the STAT3 phosphorylation, which was accompanied by elevated MYC expression in Kras-mutant cells. Immunohistochemistry showed stronger phosphorylated STAT3 (pSTAT3) and MYC staining in PanINs from diabetic KP mice than in those from euglycemic counterparts. STAT3 inhibition with 1 µM STAT3 inhibitor STATTIC in Kras-mutant pancreatic cell lines blocked the cell viability- and sphere formation-enhancing effects of the hyperglycemic environment and reversed the elevated pSTAT3 and MYC expression. MYC knockdown did not affect cell viability but did reduce sphere formation. No decrease in pSTAT3 expression was observed upon siMYC treatment. In conclusion, hyperglycemia, on a Kras-mutant background, aggravates the PanIN progression, which is accompanied by elevated pSTAT3 and MYC expression.

title: Proposal for detection of 2019-nCoV nucleic acid in clinical laboratories/ 中华检验医学杂志

text: In December, the outbreak of a novel coronavirus (2019-nCoV) in Wuhan, China, has attracted extensive global attention. On January 20, 2020,the Chinese health authorities upgraded the coronavirus to a Class B infectious disease in the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases, and considered it as Class A infectious diseases in disease control and prevention. On January 22, 2020, the 2019-nCoV nucleic acid detection test was listed as the diagnostic criteria in the "guidelines for diagnosis and treatment of pneumonia due to 2019-nCoV (Trial Version 2)" . Therefore, standardizing the operation process of the 2019-nCoV nucleic acid detection in clinical laboratories has become a top priority. It is of paramount importance to establish standard protocols for detection of the 2019-nCoV nucleic acids in clinical laboratories to improve the reliability of the results and ensure the biosafety of laboratory personnel.

title: Detection of viral SARS-CoV-2 genomes and histopathological changes in endomyocardial biopsies

text: AIMS: Since December 2019, the novel coronavirus SARS-CoV-2 has spread rapidly throughout China and keeps the world in suspense. Cardiovascular complications with myocarditis and embolism due to COVID-19 have been reported. SARS-CoV-2 genome detection in the heart muscle has not been demonstrated so far, and the underlying pathophysiological mechanisms remain to be investigated. METHODS AND RESULTS: Endomyocardial biopsies (EMBs) of 104 patients (mean age: 57.90 ± 16.37 years; left ventricular ejection fraction: 33.7 ± 14.6%, sex: n = 79 male/25 female) with suspected myocarditis or unexplained heart failure were analysed. EMB analysis included histology, immunohistochemistry, and detection of SARS-CoV-2 genomes by real-time reverse transcription polymerase chain reaction in the IKDT Berlin, Germany. Among 104 EMBs investigated, five were confirmed with SARS-CoV-2 infected by reverse real-time transcriptase polymerase chain reaction. We describe patients of different history of symptoms and time duration. Additionally, we investigated histopathological changes in myocardial tissue showing that the inflammatory process in EMBs seemed to permeate vascular wall leading to small arterial obliteration and damage. CONCLUSIONS: This is the first report that established the evidence of SARS-CoV-2 genomes detection in EMBs. In these patients, myocardial injury ischaemia may play a role, which could explain the ubiquitous troponin increases. EMB-based identification of the cause of myocardial injury may contribute to explain the different evolution of complicated SARS-CoV-2-infection and to design future specific and personalized treatment strategies.


title: Hand Sanitizers: A Review of Ingredients, Mechanisms of Action, Modes of Delivery, and Efficacy Against Coronaviruses

text: BACKGROUND: The emergence of the novel virus, SARS-CoV-2, has posed unprecedented challenges to public health around the world. Currently, strategies to deal with COVID-19 are purely supportive and preventative, aimed at reducing transmission. An effective and simple method for reducing transmission of infections in the public or healthcare settings is hand hygiene. Unfortunately, little is known regarding the efficacy of hand sanitizers against SARS-CoV-2. METHODS: In this review, an extensive literature search was performed to succinctly summarize the primary active ingredients and mechanisms of action of hand sanitizers, compare the effectiveness and compliance of gel and foam sanitizers, and predict whether alcohol and non-alcohol hand sanitizers would be effective against SARS-CoV-2. RESULTS: Most alcohol based hand sanitizers are effective at inactivating enveloped viruses, including coronaviruses. With what is currently known in the literature, one may not confidently suggest one mode of hand sanitizing delivery over the other. When hand washing with soap and water is unavailable, a sufficient volume of sanitizer is necessary to ensure complete hand coverage, and compliance is critical for appropriate hand hygiene. CONCLUSIONS: By extrapolating effectiveness of hand sanitizers on viruses of similar structure to SARS-CoV-2, this virus should be effectively inactivated with current hand hygiene products, though future research should attempt to determine this directly.


Orthopedic surgery post COVID-19: an opportunity for innovation and transformation


title: Best Practice Guidelines for the Management of Acute Craniomaxillofacial Trauma During the COVID-19 Pandemic

text: Coronavirus disease 2019 (COVID-19) is an infectious disease that is caused by severe respiratory syndrome coronavirus 2. Although elective surgical procedures are being cancelled in many parts of the world during the COVID-19 pandemic, acute craniomaxillofacial (CMF) trauma will continue to occur and will need to be appropriately managed. Surgical procedures involving the nasal, oral, or pharyngeal mucosa carry a high risk of transmission due to aerosolization of the virus which is known to be in high concentration in these areas. Intraoperative exposure to high viral loads through aerosolization carries a very high risk of transmission, and the severity of the disease contracted in this manner is worse than that transmitted through regular community transmission. This places surgeons operating in the CMF region at particularly high risk during the pandemic. There is currently a paucity of information to delineate the best practice for the management of acute CMF trauma during the COVID-19 pandemic. In particular, a clear protocol describing optimal screening, timing of intervention and choice of personal protective equipment, is needed. The authors have proposed an algorithm for management of CMF trauma during the COVID-19 pandemic to ensure that urgent and emergent CMF injuries are addressed appropriately while optimizing the safety of surgeons and other healthcare providers. The algorithm is based on available evidence at the time of writing. As the COVID-19 pandemic continues to evolve and more evidence and better testing becomes available, the algorithm should be modified accordingly.


title: Social Distancing as a Health Behavior: County-Level Movement in the United States During the COVID-19 Pandemic Is Associated with Conventional Health Behaviors

text: BACKGROUND: Social distancing-when people limit close contact with others outside their household-is a primary intervention available to combat the COVID-19 pandemic. The importance of social distancing is unlikely to change until effective treatments or vaccines become widely available. However, relatively little is known about how best to promote social distancing. Applying knowledge from social and behavioral research on conventional health behaviors (e.g., smoking, physical activity) to support public health efforts and research on social distancing is promising, but empirical evidence supporting this approach is needed. PURPOSE: We examined whether one type of social distancing behavior-reduced movement outside the home-was associated with conventional health behaviors. METHOD: We examined the association between GPS-derived movement behavior in 2,858 counties in USA from March 1 to April 7, 2020 and the prevalence of county-level indicators influenced by residents' conventional health behaviors. RESULTS: Changes in movement were associated with conventional health behaviors, and the magnitude of these associations were similar to the associations among the conventional health behaviors. Counties with healthier behaviors-particularly less obesity and greater physical activity-evidenced greater reduction in movement outside the home during the initial phases of the pandemic in the USA. CONCLUSIONS: Social distancing, in the form of reduced movement outside the home, is associated with conventional health behaviors. Existing scientific literature on health behavior and health behavior change can be more confidently used to promote social distancing behaviors during the COVID-19 pandemic.


title: Estudio de contactos en infectados por SARS-CoV-2. El papel fundamental de la Atención Primaria y de la Salud Pública./ [Contact tracing in patients infected with SARS-CoV-2. The fundamental role of Primary Health Care and Public Health]

text: The aim of this study was to promote the rapid identification of the contacts of patients infected with SARS-CoV-2 and therefore the control of the pandemic. Different methodologies and recommendations on contact tracing for Primary Health Care (PHC) and Public Health Services (PHS), like articles in Pubmed about COVID-19 and contact tracing, official contact definitions, the classic contact tracing model in tuberculosis (TB), information about apps for contact tracing and the role of the diagnostic tests, were reviewed. To establish efficient prevention and control measures, it is always necessary to implement contact tracing based on clinical suspicion, early diagnosis and isolation of cases and contacts and their follow-up. The classic contact tracing model in TB can be applied to this new infection, but accelerating the process given its acute nature and its potential severity. Good coordination between PHC and PHS and having sufficient resources is essential.

title: Mental status of patients with chronic insomnia in China during COVID-19 epidemic

text: AIM: To study the sleep and mental health of chronic insomnia patients in China during coronavirus disease in 2019 (COVID-19) epidemic. METHODS: A total of 764 patients with chronic insomnia were included in this study. From 17 January 2020 to 24 January 2020, insomnia, anxiety and physical symptoms were evaluated online, and they were followed up for 4 and 8 weeks. Main outcomes and indicators were assessed using the Pittsburgh Sleep Quality Index (PSQI) and each factor score, the General Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-15 (PHQ-15), respectively. In addition, insomnia, anxiety and physical symptoms were assessed at baseline and at the end of fourth and eighth weeks. Wilcoxon signed rank test was used to compare the changes in patients' scale scores at different time points. RESULTS: Among the 764 participants, there were 755 and 738 evaluators who completed the fourth and eighth weeks, respectively, and the questionnaire completion rates were 98.82% and 96.60%, respectively. Among them, there are 459 (60.0%) aged 41-60 years old, 546 (71.5%) women, 218 (28.5%) men and 313 (41%) college degrees. After 8 weeks of follow-up, the differences in sleep status, anxiety symptoms and physical symptoms were statistically significant. Among the factors of PSQI, there were differences in subjective sleep quality, sleep latency, sleep duration, sleep disturbance (disorder), sleep efficiency and daytime function. At 4 weeks of follow-up, there was a statistically significant difference in the use of hypnotic drugs; at 8 weeks of follow-up, there was no statistically significant difference in the use of hypnotic drugs. CONCLUSION: Under the influence of the COVID-19, the sleep status and anxiety of patients with chronic insomnia are affected by the epidemic.


title: Impact of building ventilation systems and habitual indoor incense burning on SARS-CoV-2 virus transmissions in Middle Eastern countries

text: Majority of countries across the globe have employed improving building ventilation, quarantine, social distancing, and disinfections as a general measure of preventing SARS-CoV-2 virus transmissions. However, arid Middle Eastern countries with hot climate (elevated outdoor temperature and humidity levels) are experiencing a different situation. Unfortunately, these harsh ambient climatic conditions in Middle Eastern countries make it impossible for most buildings to utilize natural/mechanical ventilation systems. Besides, indoor air temperatures of most buildings are very low due to overconsumption of air conditioning, thereby, it can be a potential factor of virus spread in most residential homes and public buildings. Most importantly, habitual indoor burning of incense which is the major source of coarse (PM10; aerodynamic diameter <10 µm) and fine (PM2.5; aerodynamic diameter <2.5 µm) particulate matters (PM) could facilitate the transmission of SARS-CoV-2 virus droplets and particles in indoor environments. In fact, it increases the spread of the virus via inhalation in these countries, especially where the wearing of masks is not regulated in public, commercial and residential buildings. It is therefore highly recommended for the relevant public health agencies to critically assess the role of poor indoor environmental conditions including the burning of incense on virus transmissions, which may help to develop control measures for the future viral outbreak effectively.


title: Structure-based virtual screening and molecular dynamics simulation of SARS-CoV-2 Guanine-N7 methyltransferase (nsp14) for identifying antiviral inhibitors against COVID-19

text: The recent pandemic caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) calls the whole world into a medical emergency. For tackling Coronavirus Disease 2019 (COVID-19), researchers from around the world are swiftly working on designing and identifying inhibitors against all possible viral key protein targets. One of the attractive drug targets is guanine-N7 methyltransferase which plays the main role in capping the 5'-ends of viral genomic RNA and sub genomic RNAs, to escape the host's innate immunity. We performed homology modeling and molecular dynamic (MD) simulation, in order to understand the molecular architecture of Guanosine-P3-Adenosine-5',5'-Triphosphate (G3A) binding with C-terminal N7-MTase domain of nsp14 from SARS-CoV-2. The residue Asn388 is highly conserved in present both in N7-MTase from SARS-CoV and SARS-CoV-2 and displays a unique function in G3A binding. For an in-depth understanding of these substrate specificities, we tried to screen and identify inhibitors from the Traditional Chinese Medicine (TCM) database. The combination of several computational approaches, including screening, MM/GBSA, MD simulations, and PCA calculations, provides the screened compounds that readily interact with the G3A binding site of homology modeled N7-MTase domain. Compounds from this screening will have strong potency towards inhibiting the substrate-binding and efficiently hinder the viral 5'-end RNA capping mechanism. We strongly believe the final compounds can become COVID-19 therapeutics, with huge international support.Communicated by Ramaswamy H. Sarma.

title: Chronic heart diseases as the most prevalent comorbidities among deaths by COVID-19 in Brazil

text: Age, sex and presence of comorbidities are risk factors associated with COVID-19. Hypertension, diabetes and heart disease are the most common comorbidities in patients with COVID-19. The objective of this study was to estimate the prevalence of patients with comorbidities who died of COVID-19 in Brazil. Searches of data were carried out on the official pages of the 26 State health departments and the federal district. The random-effect method was used to calculate the prevalence of patients with comorbidities who died. From the beginning of the pandemic in Brazil until May 20, 2020, 276,703 cases of COVID-19 were notified in Brazil, 6.4% died, 58.6% of whom were male. The prevalence of comorbidities among deaths was 83% (95% CI: 79 - 87), with heart disease and diabetes being the most prevalent. To our knowledge, this study represents the first large analysis of cases of patients with confirmed COVID-19 in Brazil. There is a high prevalence of comorbidities (83%) among patients who died from COVID-19 in Brazil, with heart disease being the most prevalent. This is important considering the possible secondary effects produced by drugs such as hydroxychloroquine.

text: High-quality clinical study on traditional Chinese medicine is of great significance to effectively control new public health emergencies represented by outbreaks of infectious diseases and ensure people's health and safety, but it still faces a series of ethical issues. Based on the seven core values of equity, good deeds, effectiveness, respect for individuals, freedom, reciprocity, and solida-rity proposed in the Guidelines for Management of Ethical Issues in Outbreaks of Infectious Diseases, this article emphasizes the characteristics and laws of clinical studies on traditional Chinese medicine. Main points of ethical review of traditional Chinese medicine were summarized in the aspects of overall concept, syndrome differentiation and treatment, prevention before disease onset, cultural value, and clinical basis. Based on the outbreak of coronavirus disease 2019(COVID-19), we collected relevant registered Chinese medicine clinical studies, summarized the core issues of the ethics review for COVID-19, and further improved the traditional Chinese medicine ethics review system and resources, so as to better serve ethical review and scientific studies in public health emergencies.

title: Autopsy Report with Clinical Pathological Correlation

text: Since making its debut on the global stage in December 2019, Coronavirus Disease 2019 (COVID-19) has afflicted nearly four million people and caused hundreds of thousands of deaths. Case reports and case series depicting the clinical effects of the causative virus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) have been published, yet few demonstrate the cytopathologic alterations of this disease. We present a clinical-pathological correlation report of a previously healthy Hispanic woman with laboratory-confirmed COVID-19 who had typical features of acute respiratory distress syndrome (ARDS), and also showed cardiac abnormalities thought to represent fulminant viral myocarditis. Congruent with the ARDS clinical impression, autopsy findings were remarkable for extensive and markedly severe acute lung injury consistent with viral pneumonia, characterized by diffuse alveolar damage, pulmonary infarction, severe pulmonary edema, desquamation of pneumocytes with intraalveolar aggregation, and pneumocyte morphological alterations suspicious for viral cytopathic effect. However, there was incongruence between the clinical impression and the cardiovascular pathology findings in that viral myocarditis was not detected on histopathologic evaluation. This case highlights the importance of pathologic corroboration of the clinical impression and, in addition, illuminates the key role autopsy plays during a pandemic by providing valuable insight into viral pathology in tissues.

title: Preparing for the coming transnational cancer crisis amid the COVID-19 pandemic

text: The continuing outbreak of the coronavirus disease 2019 (COVID-19) caused by the novel coronavirus SARS-CoV-2 has inflicted considerable burdens onto the health system of China, the world's most populous country. Remarkably, among spectrum of potential mitigation strategies, the Chinese government has implemented all-out lockdowns on large geographical areas, unprecedented in the modern era. This inevitably undermined the right to healthcare of many who now faced great difficulty in getting treatment, especially those with cancer or other life-threatening issues. We elaborate and discuss the medico-legal and human rights consideration triggered by the lockdowns, the unprecedented mass quarantine of Hubei province in China, and the suspension of normal healthcare services. We argue that the same challenge will now be faced by other countries, particularly the USA, Italy, Spain, and France, as the epicentres of COVID-19 has shifted to Europe and the Americas.


title: Nervous system involvement after infection with COVID-19 and other coronaviruses

text: Viral infections have detrimental impacts on neurological functions, and even to cause severe neurological damage. Very recently, coronaviruses (CoV), especially severe acute respiratory syndrome CoV 2 (SARS-CoV-2), exhibit neurotropic properties and may also cause neurological diseases. It is reported that CoV can be found in the brain or cerebrospinal fluid. The pathobiology of these neuroinvasive viruses is still incompletely known, and it is therefore important to explore the impact of CoV infections on the nervous system. Here, we review the research into neurological complications in CoV infections and the possible mechanisms of damage to the nervous system.

In a major London teaching hospital, 66/435 (15%) of COVID-19 inpatient cases between 2 March and 12 April 2020 were definitely or probably hospital-acquired, through varied transmission routes. The case fatality was 36%. Nosocomial infection rates fell following comprehensive infection prevention and control measures.


Sensitivity of Chest CT for COVID-19: Comparison to RT-PCR


title: Ethyl alcohol threshold test: a fast, reliable and affordable olfactory Assessment tool for COVID-19 patients

text: OBJECTIVE: COVID-19 patients may present mild symptoms. The identification of paucisymptomatic patients is paramount in order to interrupt the transmission chain of the virus. Olfactory loss could be one of those early symptoms which might help in the diagnosis of COVID-19 patients. In this study, we aim to develop and validate a fast, inexpensive, reliable and easy-to-perform olfactory test for the screening of suspected COVID-19 patients. STUDY DESIGN: Phase I was a case-control study and Phase II a transversal descriptive study. SUBJECTS AND METHODS: Olfaction was assessed with the ethyl alcohol threshold test and symptoms with visual analogue scales. The study was designed in two phases: In Phase I, we compared confirmed COVID-19 patients and healthy controls. In Phase II, patients with suspected COVID-19 infection referred for testing were studied. RESULTS: 275 participants were included in Phase I, 135 in Phase II. The ROC curve showed an AUC of 0.749 in Phase I, 0.737 in Phase II. The cutoff value which offered the highest amount of correctly classified patients was ≥ 2 (10% alcohol) for all age intervals. The odds ratio was 8.19 in Phase I, 6.56 in Phase II with a 75% sensitivity. When cases report normal sense of smell (VAS < 4), it misdiagnoses 57.89% of patients detected by the alcohol threshold test. CONCLUSION: The olfactory loss assessed with the alcohol threshold test has shown high sensitivity and odds ratio in both patients with confirmed COVID-19 illness and participants with suspected SARS-CoV-2 infection.


title: A prospective, randomised, double blind placebo-controlled trial to evaluate the efficacy and safety of tocilizumab in patients with severe COVID-19 pneumonia (TOC-COVID): A structured summary of a study protocol for a randomised controlled trial

text: OBJECTIVES: SARS-CoV2 infection leads to a concomitant pulmonary inflammation. This inflammation is supposed to be the main driver in the pathogenesis of lung failure (Acute Respiratory Distress Syndrome) in COVID-19. Objective of this study is to evaluate the efficacy and safety of a single dose treatment with Tocilizumab in patients with severe COVID-19. We hypothesize that Tocilizumab slows down the progression of SARS-CoV-2 induced pneumonia and inflammation. We expect an improvement in pulmonary function compared to placebo-treated patients. Desirable outcomes would be that tocilizumab reduces the number of days that patients are dependent on mechanical ventilation and reduces the invasiveness of breathing assistance. Furthermore, this treatment might result in fewer admissions to intensive care units. Next to these efficacy parameters, safety of a therapy with Tocilizumab in COVID-19 patients has to be monitored closely, since immunosuppression could lead to an increased rate of bacterial infections, which could negatively influence the patient's outcome. TRIAL DESIGN: Multicentre, prospective, 2-arm randomised (ratio 1:1), double blind, placebo-controlled trial with parallel group design. PARTICIPANTS: Inclusion criteria 1.Proof of SARS-CoV2 (Symptoms and positive polymerase chain reaction (PCR))2.Severe respiratory failure: a.Ambient air SpO2 ≤ 92% orb.Need of ≥ 6l O2/min orc.NIV (non-invasive ventilation) ord.IMV (invasive mechanical ventilation)3.Age ≥ 18 years Exclusion criteria 1.Non-invasive or invasive mechanical ventilation ≥ 48 hours2.Pregnancy or breast feeding3.Liver injury or failure (AST/ALT ≥ 5x ULN)4.Leukocytes < 2 × 103/µl5.Thrombocytes < 50 × 103/µl6.Severe bacterial infection (PCT > 3ng/ml)7.Acute or chronic diverticulitis8.Immunosuppressive therapy (e.g. mycophenolate, azathioprine, methotrexate, biologicals, prednisolone >10mg/d; exceptions are: prednisolone ≤ 10mg/d, sulfasalazine or hydroxychloroquine)9.Known active or chronic tuberculosis10.Known active or chronic viral hepatitis11.Known allergic reactions to tocilizumab or its ingredients12.Life expectation of less than 1 year (independent of COVID-19)13.Participation in any other interventional clinical trial within the last 30 days before the start of this trial14.Simultaneous participation in other interventional trials (except for participation in COVID-19 trials) which could interfere with this trial; simultaneous participation in registry and diagnostic trials is allowed15.Failure to use one of the following safe methods of contraception: female condoms, diaphragm or coil, each used in combination with spermicides; intra-uterine device; hormonal contraception in combination with a mechanical method of contraception. The data collection of the primary follow up (28 days after randomisation) takes place during the hospital stay. Subsequently, a telephone interview on the quality of life is conducted after 6 and 12 months. Participants will be recruited from inpatients at ten medical centres in Germany. INTERVENTION AND COMPARATOR: Intervention arm: Application of 8mg/kg body weight (BW) Tocilizumab i.v. once immediately after randomisation (12 mg/kg for patients with <30kg BW; total dose should not exceed 800 mg) AND conventional treatment. Control arm: Placebo (NaCl) i.v. once immediately after randomisation AND conventional treatment. MAIN OUTCOMES: Primary endpoint is the number of ventilator free days (d) (VFD) in the first 28 days after randomisation. Non-invasive ventilation (NIV), Invasive mechanical ventilation (IMV) and extracorporeal membrane oxygenation (ECMO) are defined as ventilator days. VFD's are counted as zero if the patient dies within the first 28 days. RANDOMISATION: The randomisation code will be generated by the CTU (Clinical Trials Unit, ZKS Freiburg) using the following procedure to ensure that treatment assignment is unbiased and concealed from patients and investigator staff. Randomisation will be stratified by centre and will be performed in blocks of variable length in a ratio of 1:1 within each centre. The block lengths will be documented separately and will not be disclosed to the investigators. The randomisation code will be produced by validated programs based on the Statistical Analysis System (SAS). BLINDING (MASKING): Participants, caregivers, and the study team assessing the outcomes are blinded to group assignment. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): 100 participants will be randomised to each group (thus 200 participants in total). TRIAL STATUS: Protocol Version: V 1.2, 16.04.2020. Recruitment began 27th April 2020 and is anticipated to be completed by December 2020. TRIAL REGISTRATION: The trial was registered before trial start in trial registries (EudraCT: No. 2020-001408-41, registered 21st April 2020, and DRKS: No. DRKS00021238, registered 22nd April 2020). FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol.


Changing oncology treatment paradigms in the COVID-19 pandemic


title: Chronic Living in a Communicable World

text: By April 2020, COVID-19 lockdowns had restricted the movements of over half the world's population. As health authorities advise people living with chronic conditions to self-isolate because they are at particular risk of serious complications and death, the epidemiological split between communicable and noncommunicable disease is tenuous. We argue that much more is at stake for people living with (multiple) medical conditions than being "at risk" of infection of coronavirus. We emphasize the need to attend to the long-term effects of COVID-19, but also the importance of the continued care of people living with other lifelong medical conditions.


title: Demographics, earnings, and family characteristics of workers in sectors initially affected by COVID-19 shutdowns

text: In the initial weeks of the coronavirus disease 2019 (COVID-19) pandemic, employment in several industries was especially vulnerable because of shutdown policies imposed by states, as well as a drop in demand as people engaged in social distancing This article looks at the demographic characteristics of workers in the initially highly exposed industries, as well as the characteristics and earnings of families with workers in these industries The article also uses recent Current Population Survey data to look at how various demographic groups have fared in the early weeks of the COVID-19 pandemic between February end April


An Urgent Need for "Common Cold Units" to Study COVID-19


title: CT Imaging Features of 2019 Novel Coronavirus (2019-nCoV)

text: In this retrospective case series, chest CT scans of 21 symptomatic patients from China infected with the 2019 novel coronavirus (2019-nCoV) were reviewed, with emphasis on identifying and characterizing the most common findings. Typical CT findings included bilateral pulmonary parenchymal ground-glass and consolidative pulmonary opacities, sometimes with a rounded morphology and a peripheral lung distribution. Notably, lung cavitation, discrete pulmonary nodules, pleural effusions, and lymphadenopathy were absent. Follow-up imaging in a subset of patients during the study time window often demonstrated mild or moderate progression of disease, as manifested by increasing extent and density of lung opacities.


title: Trends in clinical features of novel coronavirus disease (COVID-19): A systematic review and meta-analysis of studies published from December 2019 to February 2020

text: BACKGROUND: Since novel coronavirus disease (COVID-19) emerged, various clinical features of COVID-19 have been reported. METHODS: We conducted a systematic review of published studies reporting the clinical features of COVID-19. Two investigators independently searched PubMed (December 2019-February 2020) for eligible articles. A meta-analysis was performed to measure the frequencies of clinical outcomes and symptoms of COVID-19. A stratified analysis was conducted according to the timeline of outbreak and exposure histories: Group I, most patients were exposed to the Hunan seafood wholesale market and lived in Wuhan, Hubei province; Group II, patients lived in Hubei province but were not directly exposed to the market; and Group III, patients lived outside Hubei. RESULTS: Thirteen studies, all from China, were eligible. The estimated mortality rate among all studies was 2.12%, but that in Group I was 8.66%. The incidence of acute respiratory distress syndrome in Group I was 20.00%. Both fever and cough were major symptoms, and their frequencies were higher in Group I than in Groups II and III, while the frequency of diarrhea in Group I was lower than that in Group III. The estimated frequency of dyspnea in Group I was 37.18%, while those in Groups II and III were 16.95% and 7.03%, respectively. CONCLUSIONS: The trends in the clinical features of COVID-19 changed from December 2019 to February 2020. During this observation period, as the infection continued to spread, the clinical conditions for majority of patients became less severe with the changes in the route of transmission.

COVID-19: immunopathology and its implications for therapy


title: Worrying decrease in hospital admissions for myocardial infarction during the COVID-19 pandemic

text: BACKGROUND: How coronavirus 2019 (COVID-19) is affecting management of myocardial infarction is a matter of concern, as medical resources have been massively reorientated and the population has been in lockdown since 17 March 2020 in France. AIMS: To describe how lockdown has affected the evolution of the weekly rate of myocardial infarctions (non-ST-segment and ST-segment elevation) hospital admissions in Lyon, the second largest city in France. To verify the trend observed, the same analysis was conducted for an identical time window during 2018-2019 and for an unavoidable emergency, i.e. birth. METHODS: Based on the national hospitalisation database [Programme de médicalisation des systèmes d'information (PMSI)], all patients admitted to the main public hospitals for a principal diagnosis of myocardial infarction or birth during the 2nd to the 14th week of 2020 were included. These were compared with the average number of patients admitted for the same diagnosis during the same time window in 2018 and 2019. RESULTS: Before lockdown, the number of admissions for myocardial infarction in 2020 differed from that in 2018-2019 by less than 10%; after the start of lockdown, it decreased by 31% compared to the corresponding time window in 2018-2019. Conversely, the numbers of births remained stable across years and before and after the start of lockdown. CONCLUSION: This study strongly suggests a decrease in the number of admissions for myocardial infarction during lockdown. Although we do not have a long follow-up to determine whether this trend will endure, this is an important warning for the medical community and health authorities.


title: Linking key intervention timing to rapid decline of the COVID-19 effective reproductive number to quantify lessons from mainland China

text: Effective reproductive numbers (Rt) were calculated from data on the COVID-19 outbreak in China and linked to dates in 2020 when different interventions were enacted. From a maximum of 3.98 before the lockdown in Wuhan City, the values of Rt declined to below 1 by the second week of February, after the construction of hospitals dedicated to COVID-19 patients. The Rt continued to decline following additional measures in line with the policy of "early detection, early report, early quarantine, and early treatment." The results provide quantitative evaluations of how intervention measures and their timings succeeded, from which lessons can be learned by other countries dealing with future outbreaks.


title: Documento EMCAM (Esclerosis Múltiple Comunidad Autónoma de Madrid) para el manejo de pacientes con esclerosis múltiple durante la pandemia de SARS-CoV-2./ [EMCAM (Multiple Sclerosis Autonomous Community of Madrid) document for the management of patients with multiple sclerosis during the SARS-CoV-2 pandemic]

text: INTRODUCTION: The current SARS-CoV-2 pandemic is forcing neurologists to carry out a series of adaptations in the management of multiple sclerosis. Neurologists must weigh up the need to start or continue disease-modifying treatments against the risk of infection, the risk of complications from the infection, and the risk of multiple sclerosis activity. Since this is an unprecedented situation, most decisions are being made on the basis of a theoretical approach and the criteria of each neurologist. AIMS: The aim of this study is conduct a literature search to collect available evidence on the relationship between disease-modifying therapies in multiple sclerosis and SARS-CoV-2 infection. This evidence, together with the experience of the authors in the management of patients with multiple sclerosis during the pandemic, will make it possible to offer some proposals for the treatment and follow-up of patients in this epidemiological context. DEVELOPMENT: After the literature search and our experience in the management of patients, a number of proposals for treatment are established for each drug, which must necessarily be individualised for each patient, since, in these exceptional circumstances, their peculiarities can affect the prognosis. CONCLUSIONS: The neurologist should be aware of current evidence to assess the risk-benefit of starting, maintaining and stopping disease-modifying therapies in multiple sclerosis during the pandemic.


title: Laparoscopic anatomical segmentectomy using the transfissural Glissonean approach

text: BACKGROUND: Anatomical segmentectomy is a technically difficult procedure owing to the complexity of the segmental anatomy of the liver. In the conventional Glissonean approach from the liver hilum, the tertiary portal pedicles may be difficult to dissect because of their anatomical variations and deep location. We present a technique of purely laparoscopic anatomical segmentectomy of the liver using the transfissural Glissonean approach. METHODS: We performed purely laparoscopic anatomical segmentectomy using the transfissural Glissonean approach. This approach involved initially opening the liver parenchyma along the fissure line (main portal, right portal, and umbilical fissures). Thereafter, the target tertiary portal pedicles were approached and ligated within the liver parenchyma above the liver hilum. RESULTS: Between August 2014 and September 2019, we performed 17 cases of laparoscopic anatomical segmentectomy using the transfissural Glissonean approach. The median operative time was 200 min (range 120-310 min), and the intraoperative blood loss was 80 mL (range 30-280 mL). The median postoperative hospital stay was 6 days (range 3-9 days). There was no major morbidity or mortality. CONCLUSION: The transfissural Glissonean approach in laparoscopic anatomical segmentectomy is technically feasible because opening the fissure allows direct access to the tertiary portal pedicles.


title: An Otolaryngologist Redeployed to a COVID-19 Intensive Care Unit: Lessons Learned

text: The COVID-19 pandemic has placed a significant personnel burden on intensive care units across the globe. Physicians from various specialties, including otolaryngology, have heeded the call and been redeployed to provide support, serving in a capacity outside their usual scope of practice. The author shares personal experience from redeployment and provides a framework for otolaryngologists to maximize their impact while providing high-quality patient care and preserving their personal safety.


title: Not made for each other- Audio-Visual Dissonance-based Deepfake Detection and Localization

text: We propose detection of deepfake videos based on the dissimilarity between the audio and visual modalities, termed as the Modality Dissonance Score (MDS). We hypothesize that manipulation of either modality will lead to dis-harmony between the two modalities, eg, loss of lip-sync, unnatural facial and lip movements, etc. MDS is computed as an aggregate of dissimilarity scores between audio and visual segments in a video. Discriminative features are learnt for the audio and visual channels in a chunk-wise manner, employing the cross-entropy loss for individual modalities, and a contrastive loss that models inter-modality similarity. Extensive experiments on the DFDC and DeepFake-TIMIT Datasets show that our approach outperforms the state-of-the-art by up to 7%. We also demonstrate temporal forgery localization, and show how our technique identifies the manipulated video segments.
