title: Online Forecasting of Covid-19 Cases in Nigeria Using Limited Data

text: The novel Coronavirus disease (COVID-19) was first identified in Wuhan, China in December 2019 but later spread to other parts of the world. The disease as at the point of writing this paper has been declared a pandemic by the World Health Organization (WHO). The application of mathematical models, artificial intelligence, big data, and similar methodologies are potential tools to predict the extent of the spread and effectiveness of containment strategies to stem the transmission of this disease. In societies with constrained data infrastructures, modeling and forecasting COVID-19 becomes an extremely difficult endeavor. Nonetheless, we propose an online forecasting mechanism that streams data from the Nigeria Center for Disease Control to update the parameters of an ensemble model which in turn provides updated COVID-19 forecasts every 24 hours. The ensemble combines an Auto-Regressive Integrated Moving Average model (ARIMA), Prophet - an additive regression model developed by Facebook, and a Holt-Winters Exponential Smoothing model combined with Generalized Autoregressive Conditional Heteroscedasticity (GARCH). The outcomes of these efforts are expected to provide academic thrust in guiding the policymakers in the deployment of containment strategies and/or assessment of containment interventions in stemming the spread of the disease in Nigeria.


title: ADHD and Covid-19: Current roadblocks and future opportunities

text: Attention Deficit Hyperactivity Disorder is the commonest disorder presenting to Child and Adolescent Mental Health Services in Ireland. ADMiRE is a specialist ADHD service in South Dublin that provides assessment and intervention for >200 children and adolescents with ADHD.The first section of this article considers the impact of the Covid-19 pandemic on the provision of mental health services for young people with ADHD with specific reference to the difficulties that have been experienced in ADMiRE since the outbreak of Covid-19 in Ireland. In ADMiRE, there has been a significant reduction of face to face consultations, postponement of new assessments, difficulties with physical monitoring, delays in medication initiation, suspension of medication titration, lack of group interventions and problems with access to controlled drug prescriptions. Current guidelines and alternative ways of ensuring adequate service provision are discussed.Restrictions to mitigate the spread of Covid-19 are likely to continue for many months, and child and adolescent mental health services need to find new ways to provide a sustainable service to young people in Ireland. There is a growing evidence base for telepsychiatry, the use of technology such as video conferencing to deliver mental health care remotely, and this approach may be particularly useful in assessment and management of ADHD. The second section of this article discusses the evidence base for telepsychiatry in ADHD, and outlines factors that should be considered when developing a telepsychiatry service for children and adolescents with ADHD.

title: YouTube as a source of patient information for Coronavirus Disease (COVID-19): A content-quality and audience engagement analysis

text: YouTube is the second most popular website in the world and is increasingly being used as a platform for disseminating health information. Our aim was to evaluate the content-quality and audience engagement of YouTube videos pertaining to the SARS (severe acute respiratory syndrome)-CoV-2 virus which causes the Coronavirus Disease 2019 (COVID-19), during the early phase of the pandemic. We chose the first 30 videos for seven different search phrases: "2019 nCoV," "SARS CoV-2," "COVID-19 virus," "coronavirus treatment," "coronavirus explained," "what is the coronavirus" and "coronavirus information." Video contents were evaluated by two independent medical students with more than 5 years of experience using the DISCERN instrument. Qualitative data, quantitative data and upload source for each video was noted for a quality and audience engagement analysis. Out of the total 210 videos, 137 met our inclusion criteria and were evaluated. The mean DISCERN score was 31.33 out of 75 possible points, which indicates that the quality of YouTube videos on COVID-19 is currently poor. There was excellent reliability between the two raters (intraclass correlation coefficient = 0.96). 55% of the videos discussed prevention, 49% discussed symptoms and 46% discussed the spread of the virus. Most of the videos were uploaded by news channels (50%) and education channels (40%). The quality of YouTube videos on SARS-CoV-2 and COVID-19 is poor, however, we have listed the top-quality videos in our article as they may be effective tools for patient education during the pandemic.


title: Transcriptomic characteristics of bronchoalveolar lavage fluid and peripheral blood mononuclear cells in COVID-19 patients

text: Circulating in China and 158 other countries and areas, the ongoing COVID-19 outbreak has caused devastating mortality and posed a great threat to public health. However, efforts to identify effectively supportive therapeutic drugs and treatments has been hampered by our limited understanding of host immune response for this fatal disease. To characterize the transcriptional signatures of host inflammatory response to SARS-CoV-2 (HCoV-19) infection, we carried out transcriptome sequencing of the RNAs isolated from the bronchoalveolar lavage fluid (BALF) and peripheral blood mononuclear cells (PBMC) specimens of COVID-19 patients. Our results reveal distinct host inflammatory cytokine profiles to SARS-CoV-2 infection in patients, and highlight the association between COVID-19 pathogenesis and excessive cytokine release such as CCL2/MCP-1, CXCL10/IP-10, CCL3/MIP-1A, and CCL4/MIP1B. Furthermore, SARS-CoV-2 induced activation of apoptosis and P53 signalling pathway in lymphocytes may be the cause of patients' lymphopenia. The transcriptome dataset of COVID-19 patients would be a valuable resource for clinical guidance on anti-inflammatory medication and understanding the molecular mechansims of host response.

title: Topical recombinant human acidic fibroblast growth factor: An effective therapeutic agent for facemask wearing-induced pressure sores

text: Protecting health care workers is crucial during coronavirus disease 2019 pandemic and facemask wearing is considered an effective measure to prevent severe acute respiratory syndrome coronavirus 2 infection. However, long-time use of a facemask can cause pressure sores on the ears and nose bridge and increase the risk of infection. The topical recombinant human acidic fibroblast growth factor (rh-aFGF) was used to cure pressure sores for health care workers at Zhongfaxincheng campus of Tongji Hospital. The results from a small sample size survey conducted in Zhongfaxincheng campuses of Tongji Hospital showed that treatment with topical rh-aFGF could significantly inhibit the progression of pressure sores and accelerate the wound healing with no apparent ill-effects. Therefore, we propose that topical rh-aFGF is an effective therapeutic agent for facemask wearing-induced pressure sores and worth of popularizing and applying.


title: Evaluation of the lockdowns for the SARS-CoV-2 epidemic in Italy and Spain after one month follow up

text: From the end of February, the SARS-CoV-2 epidemic in Spain has been following the footsteps of that in Italy very closely. We have analyzed the trends of incident cases, deaths, and intensive care unit admissions (ICU) in both countries before and after their respective national lockdowns using an interrupted time-series design. Data was analyzed with quasi-Poisson regression using an interaction model to estimate the change in trends. After the first lockdown, incidence trends were considerably reduced in both countries. However, although the slopes have been flattened for all outcomes, the trends kept rising. During the second lockdown, implementing more restrictive measures for mobility, it has been a change in the trend slopes for both countries in daily incident cases and ICUs. This improvement indicates that the efforts overtaken are being successful in flattening the epidemic curve, and reinforcing the belief that we must hold on.


title: Unusual Microbleeds in Brain MRI of Covid-19 Patients

text: BACKGROUND AND PURPOSE: Covid-19, initially described as a respiratory system's infection, is currently more and more recognized as a multiorganic disease, including neurological manifestations. There is growing evidence about a potential neuroinvasive role of SARS-CoV-2. The purpose of this study is to describe new findings, in the form of cerebral microbleeds affecting different brain structures, observed in MRIs of critically ill patients. METHODS: For this purpose, the MR images of 9 patients with a common pattern of abnormal findings (2 women/7 men; 55-79 years of age; mean age: 67.7 years) were depicted. All patients were tested positive for SARS-CoV-2 and presented with delayed recovery of consciousness or important agitation, requiring brain MRI. RESULTS: All patients had suffered from severe (5/9) or moderate (4/9) acute respiratory distress syndrome, requiring prolonged stay in the intensive care unit. Their common MRI finding was the presence of microbleeds in unusual distribution with a specific predilection for the corpus callosum. Other uncommon locations of microbleeds were the internal capsule (5/9), as well as middle cerebellar peduncles (5/9). Subcortical regions were also affected in the majority of patients. CONCLUSIONS: Brain MRI raised evidence that Covid-19 or its related treatment may involve the brain with an unusual pattern of microbleeds, predominantly affecting the corpus callosum. The mechanism of this finding is still unclear but the differential diagnosis should include thrombotic microangiopathy related to direct or indirect-through the cytokine cascade-damage by the SARS-CoV-2 on the endothelium of brain's vessels, as well as mechanisms similar to the hypoxemia brain-blood-barrier injury.

False-Negative COVID-19 Testing: Considerations in Obstetrical Care


title: Distance learning in the era of COVID-19

text: The novel coronavirus (SARS-CoV-2) pandemic has necessitated a dramatic shift in how our dermatology residents and fellows are educated. Distance or online learning has become the norm, and several national and international academic societies have combined resources to assure that continuing medical education occurs during this difficult time. The purpose of this communication is to review select online resources available to dermatology trainees and to encourage our colleagues to continue to advance our specialty through distance learning.


title: Avaliação da lactatemia e das enzimas musculares de equinos Quarto de Milha submetidos à prova de laço em dupla com diferentes tipos de treinamento/ Evaluation of lactatemia and muscle enzymes in Quarter Horses subjected to team ropping with different types of training

text: O objetivo do trabalho foi avaliar a influência de diferentes tipos de treinamento sobre o condicionamento físico de equinos por meio da determinação do lactato sanguíneo e da atividade sérica de creatina quinase, aspartato aminotransferase e lactato desidrogenase após exercício físico de alta intensidade e curta duração. Amostras de sangue venoso foram obtidas de 16 equinos da raça Quarto de Milha, divididos em dois grupos: grupo de treinamento regular (GTR) e grupo de treinamento esporádico (GTE), em sete diferentes momentos: 30 minutos antes do exercício (M0), imediatamente após (M1), 30 minutos (M2), uma (M3), duas (M4), seis (M5) e 24 (M6) horas após o exercício. Para a análise estatística, os dados foram testados quanto à normalidade e homogeneidade de variâncias. Para comparar os grupos e os momentos em cada grupo foram utilizados testes paramétricos (ANOVA) para a análise das atividades séricas das enzimas musculares e não paramétricos (Mann-Whitney e Friedmann) para a análise do lactato sanguíneo (P<0,05). Não houve diferença significativa entre os grupos para nenhuma variável. No entanto, dentro dos grupos experimentais foi possível observar diferenças significativas entre os momentos avaliados, em relação ao lactato e à LDH. No GTE, foram observadas diferenças significativas quanto ao lactato, entre o M0 e o M1, com valores respectivos de 0,90 mmol/L (mín. 0,8 - máx. 1,6) e 3,65mmo/L (mín. 1,0 - máx. 5,7) e quanto à LDH, onde os valores descritos no M6 diferiram significativamente de M0, M1, M2, M3 e M4. No GTR, diferenças significativas entre os momentos experimentais foram observadas em relação à LDH, sendo que os valores observados no M6 foram os menores e diferiram significativamente daqueles encontrados no M1, M2, M3 e M4. Em conclusão, não houve diferença entre o condicionamento físico dos animais treinados regularmente e aqueles treinados esporadicamente. A baixa magnitude das elevações das concentrações de CK, AST e LDH após o exercício e o rápido retorno aos valores basais, inclusive do lactato, observados em ambos os grupos, sugere que todos os animais avaliados estavam condicionados e aptos a realizar tal atividade física.(AU)

COVID-19 gives the lie to global health expertise


title: Epidemiology of Seasonal Coronaviruses: Establishing the Context for the Emergence of Coronavirus Disease 2019

text: Public health preparedness for coronavirus (CoV) disease 2019 (COVID-19) is challenging in the absence of setting-specific epidemiological data. Here we describe the epidemiology of seasonal CoVs (sCoVs) and other cocirculating viruses in the West of Scotland, United Kingdom. We analyzed routine diagnostic data for >70 000 episodes of respiratory illness tested molecularly for multiple respiratory viruses between 2005 and 2017. Statistical associations with patient age and sex differed between CoV-229E, CoV-OC43, and CoV-NL63. Furthermore, the timing and magnitude of sCoV outbreaks did not occur concurrently, and coinfections were not reported. With respect to other cocirculating respiratory viruses, we found evidence of positive, rather than negative, interactions with sCoVs. These findings highlight the importance of considering cocirculating viruses in the differential diagnosis of COVID-19. Further work is needed to establish the occurrence/degree of cross-protective immunity conferred across sCoVs and with COVID-19, as well as the role of viral coinfection in COVID-19 disease severity.


The COVID-19 Pandemic and Pediatric Graduate Medical Education


title: Estimating the daily trend in the size of the COVID-19 infected population in Wuhan

text: BACKGROUND: The outbreak of coronavirus disease 2019 (COVID-19) has become a pandemic causing global health problem. We provide estimates of the daily trend in the size of the epidemic in Wuhan based on detailed information of 10 940 confirmed cases outside Hubei province. METHODS: In this modelling study, we first estimate the epidemic size in Wuhan from 10 January to 5 April 2020 with a newly proposed model, based on the confirmed cases outside Hubei province that left Wuhan by 23 January 2020 retrieved from official websites of provincial and municipal health commissions. Since some confirmed cases have no information on whether they visited Wuhan before, we adjust for these missing values. We then calculate the reporting rate in Wuhan from 20 January to 5 April 2020. Finally, we estimate the date when the first infected case occurred in Wuhan. RESULTS: We estimate the number of cases that should be reported in Wuhan by 10 January 2020, as 3229 (95% confidence interval [CI]: 3139-3321) and 51 273 (95% CI: 49 844-52 734) by 5 April 2020. The reporting rate has grown rapidly from 1.5% (95% CI: 1.5-1.6%) on 20 January 2020, to 39.1% (95% CI: 38.0-40.2%) on 11 February 2020, and increased to 71.4% (95% CI: 69.4-73.4%) on 13 February 2020, and reaches 97.6% (95% CI: 94.8-100.3%) on 5 April 2020. The date of first infection is estimated as 30 November 2019. CONCLUSIONS: In the early stage of COVID-19 outbreak, the testing capacity of Wuhan was insufficient. Clinical diagnosis could be a good complement to the method of confirmation at that time. The reporting rate is very close to 100% now and there are very few cases since 17 March 2020, which might suggest that Wuhan is able to accommodate all patients and the epidemic has been controlled.


title: COVID-19 in Pregnant Women: Case Series from One Large New York City Obstetrical Practice

text: OBJECTIVE: This study aimed to report a case series of pregnant women in New York City with confirmed or presumed coronavirus disease (COVID-19) infection. STUDY DESIGN: Beginning March 22, 2020, all pregnant women from one large obstetrical practice in New York City were contacted regularly to inquire about symptoms of COVID-19 (fever, cough, shortness of breath, malaise, anosmia), or sick contacts. A running log was kept of these patients, as well as all patients who underwent COVID-19 testing. For this report, we included every patient with suspected COVID-19 infection, which was defined as at least two symptoms, or a positive COVID-19 nasopharyngeal polymerase chain reaction test. RESULTS: From March 22, 2020 until April 30, 2020, 757 pregnant women in our practice were evaluated and 92 had known or suspected COVID-19 (12.2%, 95% confidence interval [CI]: 10.0-14.7%). Of these 92 women, 33 (36%) had positive COVID-19 test results. Only one woman required hospital admission for 5 days due to COVID-19 (1.1%, 95% CI: 0.2-5.9%). One other woman received home oxygen. No women required mechanical ventilation and there were no maternal deaths. One woman had an unexplained fetal demise at 14 weeks' gestation around the time of her COVID-19 symptoms. Twenty one of the 92 women have delivered, and all were uncomplicated. CONCLUSIONS: Among 92 women with confirmed or presumed COVID-19, the overall morbidity was low. These preliminary results are encouraging for pregnant women during the COVID-19 pandemic. KEY POINTS: · Coronavirus disease (COVID-19) is prevalent in New York City.. · In this case series, COVID-19 in pregnant women had a very low morbidity and no mortality.. · This preliminary data is reassuring for pregnant women at risk of COVID-19..


title: Embracing telemedicine into your otolaryngology practice amid the COVID-19 crisis: An invited commentary

text: The COVID-19 pandemic has quickly and radically altered how Otolaryngologists provide patient care in the outpatient setting. Continuity of care with established patients as well as establishment of a professional relationship with new patients is challenging during this Public Health Emergency (PHE). Many geographic areas are under "stay at home" or "shelter in place" directives from state and local governments to avoid COVID-19 exposure risks. Medicare has recently allowed "broad flexibilities to furnish services using remote communications technology to avoid exposure risks to health care providers, patients, and the community." [1] The implementation of telemedicine, or virtual, services, will help the Otolaryngologists provide needed care to patients while mitigating the clinical and financial impact of the pandemic. The significant coding and billing issues related to implementing telemedicine services are discussed to promote acceptance of this technology by the practicing Otolaryngologist. Of particular importance, outpatient visit Current Procedural Terminology® codes (99201-99215) may be used for telehealth visits performed in real-time audio and video.


SARS-CoV-2, skin lesions and the need of a multidisciplinary approach


title: Administration with Vaccinia Virus Encoding Canine Parvovirus 2 vp2 Elicits Systemic Immune Responses in Mice and Dogs

text: Canine parvovirus type 2 (CPV2) is a highly contagious cause of serious and often fatal disease in young dogs. Despite the widespread availability of attenuated vaccines, safer, more stable, and more effective CPV2 vaccine candidates are still under exploration. Vaccinia virus (VV) has already been proved to be a safe, stable, and effective vaccine vector. In this study, we generated a VV-based CPV2 vaccine candidate (VV-CPV-VP2) and then evaluated its immunogenicity in mice and dogs. The exogenous vp2 gene of CPV2, which replaced the major virulence gene hemagglutinin (ha) of VV, expressed efficiently and stably in vitro. Subsequently, intramuscular immunization of mice induced robust and lasting systemic immune responses, including neutralizing antibody against both CPV2a and CPV2b, and CPV2-VP2-specific interferon gamma (IFN-Î³) secreting T cell. In addition, administration with a high-dose of VV-CPV-VP2 did not cause significant side effects for mice, thus indicating marked safety of this vaccine candidate. Most importantly, a single-dose vaccination of VV-CPV2-VP2 elicited substantial antibody responses and provided comparable protection for dogs with attenuated CPV2 vaccine. Collectively, this study demonstrated that VV-CPV2-VP2 could be used as a promising vaccine candidate preventing CPV2 from infection for dogs.


title: Acute Hyperglycemic Crises with Coronavirus Disease-19: Case Reports

text: Since the first case was contracted by coronavirus disease-19 (COVID-19) in Daegu, Korea in February 2020, about 6,800 cases and 130 deaths have been reported on April 9, 2020. Recent studies have reported that patients with diabetes showed higher mortality and they had a worse prognosis than the group without diabetes. In poorly controlled patients with diabetes, acute hyperglycemic crises such as diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS) also might be precipitated by COVID-19. Thus, intensive monitoring and aggressive supportive care should be needed to inadequately controlled patients with diabetes and COVID-19 infection. Here, we report two cases of severe COVID-19 patients with acute hyperglycemic crises in Korea.


Monitoring the COVID-19 pandemic in sub-Saharan Africa: focusing on health facility admissions and deaths


title: Which Country is Truly Developed? COVID-19 has Answered the Question

text: The developed countries of the world were ill-prepared for the pandemic that they have suffered. When we compare developed to developing countries, the sophisticated parameters we use do not necessarily address the weaknesses in the healthcare systems of developed countries that make them susceptible to crises like the present pandemic. We strongly suggest that better preparation for such events is necessary for a country to be considered developed.


Molecular structure analyses suggest strategies to therapeutically target SARS-CoV-2


title: Novel Coronavirus Disease (COVID-19) and Central Nervous System Complications: What Neurologist Need to Know

text: The novel coronavirus (Covid-19) is a family of large enveloped non-segmented positive-sense RNA viruses which has been considered as a global health concern as it has a very high transmissibility potential. Regarding to the similarity of the virus to SARS-CoV, it is postulated that the Covid-19 accumulates mainly in the nasal epithelia and lower respiratory airways. However, there is evidence suggesting the Covid-19 neurotropism which might contribute to respiratory failure. Here in we aim to review the central nervous system complications of the Covid-19 CoV since the emergence of the virus. Keywords: Novel Coronavirus, Covid19-Cov, CNS Complication, Nervous System.

title: Potent neutralization of SARS-CoV-2 by human antibody heavy-chain variable domains isolated from a large library with a new stable scaffold

text: Effective therapies are urgently needed for COVID-19. Here we describe the identification of a new stable human immunoglobulin G1 heavy-chain variable (VH) domain scaffold that was used for the construction of a large library, lCAT6, of engineered human VHs. This library was panned against the receptor-binding domain (RBD) of the SARS-CoV-2 spike (S) glycoprotein. Two VH domains (VH ab6 and VH m397) were selected and fused to Fc for increased half-life in circulation. The VH-Fc ab6 and m397 specifically neutralized SARS-CoV-2 with high potencies (50% neutralization at 0.35 µg/ml and 1.5 µg/ml, respectively) as measured by two independent replication-competent virus neutralization assays. Ab6 and m397 competed with ACE2 for binding to RBD, suggesting a competitive mechanism of virus neutralization. These VH domains may have potential applications for prophylaxis and therapy of COVID-19 alone or in combination, as well as for diagnosis and as tools for research.


title: COVID-19 and anosmia in Tehran, Iran

text: Patients with acute olfactory disorders typically present to the otolaryngologist with both acute hyposmia and less often with anosmia. With the onset of COVID-19 we have noticed an increase in the number of patients who have presented with new onset of complete smell loss to the senior author's practice in Tehran, Iran. This anosmia and the frequency with which patients present is highly unusual. Coronaviruses have been known to cause common cold symptoms. COVID-19 infections have been described as causing more severe respiratory infections and the symptoms reported by authors from Wuhan, China have not specifically included anosmia. We describe patients who have presented during a two-week period of the COVID-19 pandemic with complete loss of sense of smell. Most had either no symptoms or mild respiratory symptoms. Many had a normal otolaryngologic exam. A relationship between COVID-19 and anosmia should be considered during the pandemic. We hypothesize that the mechanism of injury is similar to that of other coronavirus infections that cause central and peripheral neurologic deficits.


title: Bonuses and pitfalls of a paperless drive-through screening and COVID-19: A field report

text: As the world witnessed the rapid spread of SARS-CoV-2, the World Health Organization has called for governing bodies worldwide to intensify case findings, contact tracing, monitoring, and quarantine or isolation of contacts with COVID-19. Drive-through (DT) screening is a form of case detection which has recently gain preference globally. Proper implementation of this system can help remediate the outbreak.


title: Potential Antiviral Options against SARS-CoV-2 Infection

text: As of June 2020, the number of people infected with severe acute respiratory coronavirus 2 (SARS-CoV-2) continues to skyrocket, with more than 6.7 million cases worldwide. Both the World Health Organization (WHO) and United Nations (UN) has highlighted the need for better control of SARS-CoV-2 infections. However, developing novel virus-specific vaccines, monoclonal antibodies and antiviral drugs against SARS-CoV-2 can be time-consuming and costly. Convalescent sera and safe-in-man broad-spectrum antivirals (BSAAs) are readily available treatment options. Here, we developed a neutralization assay using SARS-CoV-2 strain and Vero-E6 cells. We identified the most potent sera from recovered patients for the treatment of SARS-CoV-2-infected patients. We also screened 136 safe-in-man broad-spectrum antivirals against the SARS-CoV-2 infection in Vero-E6 cells and identified nelfinavir, salinomycin, amodiaquine, obatoclax, emetine and homoharringtonine. We found that a combination of orally available virus-directed nelfinavir and host-directed amodiaquine exhibited the highest synergy. Finally, we developed a website to disseminate the knowledge on available and emerging treatments of COVID-19.


title: Characteristics of YouTube Videos in Spanish on How to Prevent COVID-19

text: OBJECTIVE: To analyze the characteristics of YouTube videos in Spanish on the basic measures to prevent coronavirus disease 2019 (COVID-19). METHODS: On 18 March 2020, a search was conducted on YouTube using the terms "Prevencion Coronavirus" and "Prevencion COVID-19". We studied the associations between the type of authorship and the country of publication with other variables (such as the number of likes and basic measures to prevent COVID-19 according to the World Health Organization, among others) with univariate analysis and a multiple logistic regression model. RESULTS: A total of 129 videos were evaluated; 37.2% were produced in Mexico (25.6%) and Spain (11.6%), and 56.6% were produced by mass media, including television and newspapers. The most frequently reported basic preventive measure was hand washing (71.3%), and the least frequent was not touching the eyes, nose, and mouth (24.0%). Hoaxes (such as eating garlic or citrus to prevent COVID-19) were detected in 15 videos (10.9%). In terms of authorship, papers produced by health professionals had a higher probability of reporting hand hygiene (OR (95% CI) = 4.20 (1.17-15.09)) and respiratory hygiene (OR (95% CI) = 3.05 (1.22-7.62)) as preventive measures. CONCLUSION: Information from YouTube in Spanish on basic measures to prevent COVID-19 is usually not very complete and differs according to the type of authorship. Our findings make it possible to guide Spanish-speaking users on the characteristics of the videos to be viewed in order to obtain reliable information.


title: Enabling and Enforcing Social Distancing Measures using Smart City and ITS Infrastructures: A COVID-19 Use Case

text: Internet of Things is a revolutionary domain that has the caliber to impact our lives and bring significant changes to the world. Several IoT applications have been envisioned to facilitate data driven and smart application for the user. Smart City and Intelligent Transportation System (ITS) offer a futuristic vision of smart, secure and safe experience to the end user, and at the same time efficiently manage the sparse resources and optimize the efficiency of city operations. However, outbreaks and pandemics like COVID-19 have revealed limitations of the existing deployments, therefore, architecture, applications and technology systems need to be developed for swift and timely enforcement of guidelines, rules and government orders to contain such future outbreaks. This work outlines novel architecture, potential use-cases and some future directions in developing such applications using Smart City and ITS.


COVID 2019-suicides: A global psychological pandemic


title: We Need Strong Public Health Care to Contain the Global Corona Pandemic

text: The corona virus (COVID-19) outbreak has spread from China to over a hundred countries in less than 2 months. Now is the time to take stock and to assess the responses of different countries to the outbreak so far. What we can learn from the global Corona pandemic so far is that strong public health systems have the resilience to address massive health threats with the collective responses they require. Privatization of health services and individualization of risks might further undermine our ability to address this and future global pandemics.


Airway management equipment and practice: time to optimise institutional, team, and personal preparedness


title: CoVista: A Unified View on Privacy Sensitive Mobile Contact Tracing Effort

text: Governments around the world have become increasingly frustrated with tech giants dictating public health policy. The software created by Apple and Google enables individuals to track their own potential exposure through collated exposure notifications. However, the same software prohibits location tracking, denying key information needed by public health officials for robust contract tracing. This information is needed to treat and isolate COVID-19 positive people, identify transmission hotspots, and protect against continued spread of infection. In this article, we present two simple ideas: the lighthouse and the covid-commons that address the needs of public health authorities while preserving the privacy-sensitive goals of the Apple and google exposure notification protocols.


title: Mask crisis during the COVID-19 outbreak

text: On December 31, 2019, the World Health Organization (WHO) reported a cluster of cases of pneumonia of unknown cause detected in Wuhan City, Hubei Province, China. As of February 29, 2020, the National Health Commission of China has reported 79,389 confirmed cases of SARS-CoV-2 infection in 34 provinces. The masks can be used to block respiratory transmission from human to human, and are an effective way to control influenza. It is, therefore, necessary to wear a mask when respiratory infectious diseases are prevalent. China has a population of 1.4 billion. Assuming that two-thirds of the people in China must wear a mask every day, the daily demand for masks will reach 900 million. The Chinese government has taken many measures to solve these problems. Additionally, more measures should be taken to properly dispose of mask garbage. Although the outbreak originated in China, person-to-person transmission of SARS-CoV-2 has been confirmed, which means that it can be spread to anywhere in the world if prevention measures fail. The issues regarding face mask shortages and garbage in China, therefore, deserve worldwide attention.


title: Achieving Safe, Effective, and Compassionate Quarantine or Isolation of Older Adults With Dementia in Nursing Homes

text: Nursing homes are facing the rapid spread of COVID-19 among residents and staff and are at the centre of the public health emergency due to the COVID-19 pandemic. As policy changes and interventions designed to support nursing homes are put into place, there are barriers to implementing a fundamental, highly effective element of infection control, namely the isolation of suspected or confirmed cases. Many nursing home residents have dementia, associated with impairments in memory, language, insight, and judgment that impact their ability to understand and appreciate the necessity of isolation and to voluntarily comply with isolation procedures. While there is a clear ethical and legal basis for the involuntary confinement of people with dementia, the potential for unintended harm with these interventions is high, and there is little guidance for nursing homes on how to isolate safely, while maintaining the human dignity and personhood of the individual with dementia. In this commentary, we discuss strategies for effective, safe, and compassionate isolation care planning, and present a case vignette of a person with dementia who is placed in quarantine on a dementia unit.

title: Geburtshilfliche Anästhesie während der SARS-CoV-2-Pandemie: Übersicht der Handlungsempfehlungen./ [Obstetric Anesthesia During the SARS-CoV-2 Pandemic - a Brief Overview of Published Recommendations for Action by National and International Specialist Societies and Committees]

text: The most common human corona viruses cause common colds. But three of these viruses cause more serious, acute diseases; Middle East Respiratory Syndrome (MERS by MERS-CoV), Severe Acute Respiratory Syndrome (SARS) by SARS-CoV and COVID-19 by SARS-CoV-2. The current outbreak was classified by the WHO as a "global public health emergency". Despite all efforts to reduce the surgical lists and to cancel or postpone non-time-critical surgical interventions, some surgical and anesthetic interventions outside of intensive care medicine are still necessary and must be performed. This is particularly true for obstetric interventions and neuraxial labor analgesia. Workload in the delivery room is presumably not going to decrease and planned cesarean sections cannot be postponed. In the meantime, the clinical course and outcome of some COVID-19 patients with an existing pregnancy or peripartum courses have been reported. There are already numerous recommendations from national and international bodies regarding the care of such patients. Some of these recommendations will be summarized in this manuscript. The selection of aspects should by no means be seen as a form of prioritization. The general treatment principles in dealing with COVID-19 patients and the recommendations for action in intensive care therapy also apply to pregnant and postpartum patients. In this respect, there are naturally considerable redundancies and only a few aspects apply strictly or exclusively to the cohort of obstetric patients. In summary, at present it must be stated that the general care recommendations that also apply to non-COVID-19 patients are initially valid with regard to obstetric anesthesia. Nevertheless, the special requirements on the part of hygiene and infection protection result in special circumstances that should be taken into account when caring for pregnant patients from an anesthetic point of view. These relate to both medical aspects, but also to a particular extent logistics issues with regard to spatial separation, staffing and material resources.


title: Implications of COVID-19 in pediatric rheumatology

text: COVID-19 (coronavirus disease 2019) pandemic caused by SARS-CoV-2, is a global public health issue threatening millions of lives worldwide. Although the infection is mild in most of the affected individuals, it may cause severe clinical manifestations such as acute respiratory distress syndrome or cytokine storm leading to death. Children are affected less, and most experience a milder disease. As rheumatologists, we deal with the uncontrolled response of the immune system, and most of the drugs we use are either immune modulators or immunosuppressants. Thus, the rheumatologists participate in the multidisciplinary management of COVID-19 patients. On the other hand, our patients with rheumatic diseases constitute a vulnerable group in this pandemic. In this review, a systematic literature search was conducted utilizing MEDLINE/PubMed and Scopus databases, and 231 COVID-19 patients with rheumatic diseases have been identified. Only one of these patients was a child. Among these, 9 (3.9%) died due to COVID-19. In light of the current data, the aspects of COVID-19 resembling rheumatic diseases, the possible reasons for why children are affected less severely, the hypothetic role of available vaccines in preventing COVID-19, the unique position of patients with rheumatic diseases in this pandemic, and the use of anti-rheumatic drugs in COVID-19 treatment are discussed.


Treatment delays in oncology patients during COVID-19 pandemic: A perspective


title: Wearable Technology and How This Can Be Implemented into Clinical Practice

text: PURPOSE OF REVIEW: Our day-to-day life is saturated with health data that was previously out of reach. Over the last decade, new devices and fitness technology companies are attempting to tap into this data, uncovering a treasure trove of useful information that, when applied correctly, has the potential to revolutionize the way we approach healthcare and chronic conditions like asthma, especially in the wake of the COVID-19 pandemic. RECENT FINDINGS: By harnessing exciting developments in personalization, digitization, wellness, and patient engagement, care providers can improve health outcomes for our patients in a way we have never been able to do in the past. While new technologies to capture individual health metrics are everywhere, how can we use this information to make a real difference in our patients' lives? Navigating the complicated landscape of personal wearable devices, asthma inhaler sensors, and exercise apps can be daunting to even the most tech savvy physician. This manuscript will give you the tools necessary to make lasting changes in your patients' lives by exposing them to a world of usable, affordable, and relatable health technology that resonates with their personal fitness and wellness goals. These tools will be even more important post-COVID-19, as the landscape of clinical outpatient care changes from mainly in-person visits to a greater reliance on telemedicine and remote monitoring.


title: Current pharmacological treatments for COVID-19: What's next?

text: Since December 2019 SARS-Cov-2 was found responsible for the disease COVID-19, which has spread worldwide. No specific therapies/vaccines are yet available for the treatment of COVID-19. Drug repositioning may offer a strategy and a number of drugs have been repurposed, including lopinavir/ritonavir, remdesivir, favipiravir and tocilizumab. This paper describes the main pharmacological properties of such drugs administered to patients with COVID-19, focusing on their antiviral, immune-modulatory and/or anti-inflammatory actions. Where available, data from clinical trials involving patients with COVID-19 are reported. Preliminary clinical trials seem to support their benefit. However, such drugs in COVID-19 patients have peculiar safety profiles. Thus, adequate clinical trials are necessary for these compounds. Nevertheless, while waiting for effective preventive measures i.e. vaccines, many clinical trials on drugs belonging to different therapeutic classes are currently underway. Their results will help us in defining the best way to treat COVID-19 and reducing its symptoms and complications.


title: COVID-19: A Personalized Cardiometabolic Approach for Reducing Complications and Costs. The Role of Aging beyond Topics

text: COVID 19 is much more than an infectious disease by SARS-CoV-2 followed by a disproportionate immune response. An older age, diabetes and history of cardiovascular disease, especially hypertension, but also chronic heart failure and coronary artery disease among others, are between the most important risk factors. In addition, during the hospitalization both hyperglycaemia and heart failure are frequent. Less frequent are acute coronary syndrome, arrhythmias and stroke. Accordingly, not all prolonged stays or even deaths are due directly to SARS-CoV-2. To our knowledge, this is the first review, focusing both on cardiovascular and metabolic aspects of this dreadful disease, in an integrated and personalized way, following the guidelines of the Cardiometabolic Health/Medicine. Therefore, current personalized aspects such as ACEIs and ARBs, the place of statins and the most appropriate management of heart failure in diabetics are analysed. Aging, better than old age, as a dynamic process, is also considered in this review for the first time in the literature, and not only as a risk factor attributed to cardiovascular and non-cardiovascular comorbidities. Immunosenescence is also approached to build healthier elders, so they can resist present and future infectious diseases, and not only in epidemics or pandemics. In addition, to do this we must start knowing the molecular mechanisms that underlying Aging process in general, and immunosenescence in particular. Surprisingly, the endoplasmic reticulum stress and autophagy are implicated in both process. Finally, with a training in all the aspects covered in this review, not only the hospital stay, complications and costs of this frightening disease in high-risk population should be reduced. Likely, this paper will open a gate to the future for open-minded physicians.


title: A Macroeconomic SIR Model for COVID-19

text: The current COVID-19 pandemic and subsequent lockdowns have highlighted the close and delicate relationship between a country's public health and economic health. Macroeconomic models that use preexisting epidemic models to calculate the impacts of a disease outbreak are therefore extremely useful for policymakers seeking to evaluate the best course of action in such a crisis. We develop an SIR model of the COVID-19 pandemic that explicitly considers herd immunity, behavior-dependent transmission rates, remote workers, and indirect externalities of lockdown. This model is presented as an exit time control problem where lockdown ends when the population achieves herd immunity, either naturally or via a vaccine. A social planner prescribes separate levels of lockdown for two separate sections of the adult population: low-risk (ages 20-64) and high-risk (ages 65 and over). These levels are determined via optimization of an objective function which assigns a macroeconomic cost to the level of lockdown and the number of deaths. We find that, by ending lockdowns once herd immunity is reached, high-risk individuals are able to leave lockdown significantly before the arrival of a vaccine without causing large increases in mortality. Moreover, if we incorporate a behavior-dependent transmission rate which represents increased personal caution in response to increased infection levels, both output loss and total mortality are lowered. Lockdown efficacy is further increased when there is less interaction between low- and high-risk individuals, and increased remote work decreases output losses. Overall, our model predicts that a lockdown which ends at the arrival of herd immunity, combined with individual actions to slow virus transmission, can reduce total mortality to one-third of the no-lockdown level, while allowing high-risk individuals to leave lockdown well before vaccine arrival.

title: Acute cor pulmonale from saddle pulmonary embolism in a patient with previous COVID-19: should we prolong prophylactic anticoagulation?

text: Severe coronavirus disease 2019 (COVID-19) is known to be associated with a heightened risk of thromboembolism. However, the risk associated with mild and moderate illness from COVID-19 is unknown, and there is no current recommendation for prophylaxis against thromboembolism in patients after hospital treatment, unless there are established thrombophilic risk factors. We report the case of a 52-year-old woman who presented with massive saddle pulmonary embolism 1 week after initial hospital discharge, which was treated successfully with thrombolysis. This case raises the question of whether extended prophylactic anticoagulation should be considered even in low-risk COVID-19 cases.

title: C-reactive protein levels in the early stage of COVID-19

text: BACKGROUND: COVID-19 is a new infectious disease, for which there is currently no treatment. It is therefore necessary to explore biomarkers to determine the extent of lung lesions and disease severity. OBJECTIVE: We aimed to assess the usefulness of CRP levels in the early stage of COVID-19 and to correlate them with lung lesions and severe presentation. METHODS: Confirmed cases of COVID-19 were selected at the Fever Unit in two regions of Guizhou, China. On admission CRP levels were collected, and the diameter of the largest lung lesion was measured in the most severe lung lesion by lung CT scan. Differences in the diameter and CRP levels were compared in the following groups of patients: mild group, moderate group, severe group, and critical group. RESULT: CRP levels and the diameter of the largest lung lesion in the moderate group were higher than those in the mild group (Mann-Whitney test=-2.647, -2.171, PË0.05), those in the severe group were higher than those in the moderate group (Mann-Whitney test=0.693, -2.177, PË0.05), and those in the critical group were higher than those in the severe group (Mann-Whitney test=-0.068, -1.549, PË0.05). The difference was statistically significant. CRP levels were positively correlated with the diameter of lung lesion and severe presentation (correlation coefficient=0.873, 0.734, PË0.001). CONCLUSION: In the early stage of COVID-19 CRP levels were positively correlated with lung lesions and could reflect disease severity.


title: Global, regional, and national estimates of the population at increased risk of severe COVID-19 due to underlying health conditions in 2020: a modelling study

text: BACKGROUND: The risk of severe COVID-19 if an individual becomes infected is known to be higher in older individuals and those with underlying health conditions. Understanding the number of individuals at increased risk of severe COVID-19 and how this varies between countries should inform the design of possible strategies to shield or vaccinate those at highest risk. METHODS: We estimated the number of individuals at increased risk of severe disease (defined as those with at least one condition listed as "at increased risk of severe COVID-19" in current guidelines) by age (5-year age groups), sex, and country for 188 countries using prevalence data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 and UN population estimates for 2020. The list of underlying conditions relevant to COVID-19 was determined by mapping the conditions listed in GBD 2017 to those listed in guidelines published by WHO and public health agencies in the UK and the USA. We analysed data from two large multimorbidity studies to determine appropriate adjustment factors for clustering and multimorbidity. To help interpretation of the degree of risk among those at increased risk, we also estimated the number of individuals at high risk (defined as those that would require hospital admission if infected) using age-specific infection-hospitalisation ratios for COVID-19 estimated for mainland China and making adjustments to reflect country-specific differences in the prevalence of underlying conditions and frailty. We assumed males were twice at likely as females to be at high risk. We also calculated the number of individuals without an underlying condition that could be considered at increased risk because of their age, using minimum ages from 50 to 70 years. We generated uncertainty intervals (UIs) for our estimates by running low and high scenarios using the lower and upper 95% confidence limits for country population size, disease prevalences, multimorbidity fractions, and infection-hospitalisation ratios, and plausible low and high estimates for the degree of clustering, informed by multimorbidity studies. FINDINGS: We estimated that 1·7 billion (UI 1·0-2·4) people, comprising 22% (UI 15-28) of the global population, have at least one underlying condition that puts them at increased risk of severe COVID-19 if infected (ranging from <5% of those younger than 20 years to >66% of those aged 70 years or older). We estimated that 349 million (186-787) people (4% [3-9] of the global population) are at high risk of severe COVID-19 and would require hospital admission if infected (ranging from <1% of those younger than 20 years to approximately 20% of those aged 70 years or older). We estimated 6% (3-12) of males to be at high risk compared with 3% (2-7) of females. The share of the population at increased risk was highest in countries with older populations, African countries with high HIV/AIDS prevalence, and small island nations with high diabetes prevalence. Estimates of the number of individuals at increased risk were most sensitive to the prevalence of chronic kidney disease, diabetes, cardiovascular disease, and chronic respiratory disease. INTERPRETATION: About one in five individuals worldwide could be at increased risk of severe COVID-19, should they become infected, due to underlying health conditions, but this risk varies considerably by age. Our estimates are uncertain, and focus on underlying conditions rather than other risk factors such as ethnicity, socioeconomic deprivation, and obesity, but provide a starting point for considering the number of individuals that might need to be shielded or vaccinated as the global pandemic unfolds.

Return to play after the COVID-19 pandemic: a commentary by the Editor in Chief


title: Determination of Air Filter Anti-Viral Efficiency against an Airborne Infectious Virus

text: Recently, various studies have reported the prevention and treatment of respiratory infection outbreaks caused by lethal viruses. Consequently, a variety of air filters coated with antimicrobial agents have been developed to capture and inactivate virus particles in continuous airflow conditions. However, since aerosolized infectious viral-testing is inadvisable due to safety concerns, their anti-viral capability has only been tested by inserting the filters into liquid media, where infectious virus particles disperse. In this study a novel method of determining anti-viral performance of an air filter against airborne infectious viruses is presented. Initially, anti-viral air filter tests were conducted. Firstly, by an air-media test, in which the air filter was placed against an aerosolized non-infectious virus. Secondly, by a liquid-media test, in which the filter was inserted into a liquid medium containing a non-infectious virus. Subsequently, a correlation was established by comparing the susceptibility constants obtained between the two medium tests and an association was found for the air medium test with infectious virus. After ensuring the relationship did not depend on the virus species, the correlation was used to derive the results of the air-medium test from the results of the liquid-medium test.


title: The crucible of COVID-19: what the pandemic is teaching us about health research systems

text: The global health crisis created by COVID-19 is providing valuable insights into the strengths of our health research system and, perhaps even more clearly, displaying its weaknesses. Much of what is being shown so plainly in the current context is not truly new. We are being reminded that health research systems are slow and noisy as well as that there is a desire for research to inform decision-making, that researchers are great collaborators, and that the walls we are so quick to erect between health research and health practice are unhelpful facades. It is our hope that the clarity with which these issues are being demonstrated by COVID-19 might provide the impetus to address these challenges and seize these opportunities to improve our health research system, for the benefit for communities facing COVID-19 now, and for the benefit of us all in facing the further health challenges that are sure to come.


title: Characteristics of Health Care Personnel with COVID-19 - United States, February 12-April 9, 2020

text: As of April 9, 2020, the coronavirus disease 2019 (COVID-19) pandemic had resulted in 1,521,252 cases and 92,798 deaths worldwide, including 459,165 cases and 16,570 deaths in the United States (1,2). Health care personnel (HCP) are essential workers defined as paid and unpaid persons serving in health care settings who have the potential for direct or indirect exposure to patients or infectious materials (3). During February 12-April 9, among 315,531 COVID-19 cases reported to CDC using a standardized form, 49,370 (16%) included data on whether the patient was a health care worker in the United States; including 9,282 (19%) who were identified as HCP. Among HCP patients with data available, the median age was 42 years (interquartile range [IQR] = 32-54 years), 6,603 (73%) were female, and 1,779 (38%) reported at least one underlying health condition. Among HCP patients with data on health care, household, and community exposures, 780 (55%) reported contact with a COVID-19 patient only in health care settings. Although 4,336 (92%) HCP patients reported having at least one symptom among fever, cough, or shortness of breath, the remaining 8% did not report any of these symptoms. Most HCP with COVID-19 (6,760, 90%) were not hospitalized; however, severe outcomes, including 27 deaths, occurred across all age groups; deaths most frequently occurred in HCP aged ≥65 years. These preliminary findings highlight that whether HCP acquire infection at work or in the community, it is necessary to protect the health and safety of this essential national workforce.

title: Histopathology of COVID-19 pneumonia in two non-oncological, non-hospitalised cases as a reliable diagnostic benchmark

text: In lung cancer patients infected with COVID-19, pathological features are not easy to distinguish. This report presents detailed histopathological findings in two non-neoplastic subjects whose out-of-hospital deaths were caused by COVID-19 infection. These 'pure' cases differ in the time of presentation of symptoms, the phase of lung anatomopathological patterns (acute lung injury versus diffuse alveolar damage) and the mechanism of death. The results provide a valid diagnostic benchmark for evaluating the evolution of COVID-19 pneumonia.


title: Temperature and precipitation associate with Covid-19 new daily cases: A correlation study between weather and Covid-19 pandemic in Oslo, Norway

text: This study aims to analyze the correlation between weather and covid-19 pandemic in the capital city of Norway, Oslo. This study employed a secondary data analysis of covid-19 surveillance data from the Norwegian public health institute and weather data from the Norwegian Meteorological institute. The components of weather include minimum temperature (°C), maximum temperature (°C), temperature average (°C), normal temperature (°C), precipitation level (mm) and wind speed (m/s). Since normality was not fulfilled, a non-parametric correlation test was used for data analysis. Maximum temperature (r = 0.347; p = .005), normal temperature(r = 0.293; p = .019), and precipitation level (r = -0.285; p = .022) were significantly correlated with covid-19 pandemic. The finding might serve as an input to a strategy making in the prevention of covid-19 as the country prepare to enter into a new weather season.

text: Radio is the medium best adapted to crises This fact has been demonstrated throughout the history of Spain both in the 1981 coup d'état attempt and in the terrorist attacks of 11 March 2004 The question that arises then is if in the situation of lockdown suffered by the Spanish population due to the Covid-19 pandemic radio is also playing a relevant role This study comes to answer this question through a survey answered by 560 radio listeners during the lockdown The research has focused on knowing the listening habits, radio consumption, and the perception that these listeners have of the medium in this crisis The data indicate that the respondents have changed their listening habits and have increased their medium consumption During the lockdown, they are listening to the radio mostly in the living room, bedroom, and kitchen while cleaning or cooking They are also consuming more hours of radio, more stations (of a different ideological signs), and more shows For these listeners, radio is positioned as the medium that is best covering information about the coronavirus and the one that they consider most credible, closest, that most stimulates the imagination, reduces loneliness, and it is most distracting Overall, the results of this study allow us to conclude that the radio is once again playing a leading role in the coronavirus crisis, as it has occurred throughout the history of Spain


title: Impact of corticosteroid therapy on outcomes of persons with SARS-CoV-2, SARS-CoV, or MERS-CoV infection: a systematic review and meta-analysis

text: We performed a meta-analysis to determine safety and efficacy of corticosteroids in SARS-CoV-2, SARS-CoV, and MERS-CoV infections. We searched PubMed, Web of Science, Medline, WanFang Chinese database, and ZhiWang Chinese database using Boolean operators and search terms covering SARS-CoV-2, SARS-CoV, OR MERS-CoV AND corticosteroids to find appropriate studies. Review Manager 5.3 was used to analyze results of meta-analysis. Observational studies were analyzed for quality using the modified Newcastle-Ottawa scale and randomized clinical trials, using the Jadad scale. Subjects were divided into those with severe-only and other (severe and not severe) cohorts based on published criteria. Efficacy endpoints studied included mortality, hospitalization duration, rates of intensive care unit (ICU) admission, use of mechanical ventilation, and a composite endpoint (death, ICU admission, or mechanical ventilation). We included 11 reports including 10 cohort studies and 1 randomized clinical trial involving 5249 subjects (2003-2020). Two discussed the association of corticosteroids and virus clearing and 10 explored how corticosteroids impacted mortality, hospitalization duration, use of mechanical ventilation, and a composite endpoint. Corticosteroid use was associated with delayed virus clearing with a mean difference (MD) = 3.78 days (95% confidence Interval [CI] = 1.16, 6.41 days; I2 = 0%). There was no significant reduction in deaths with relative Risk Ratio (RR) = 1.07 (90% CI = 0.81; 1.42; I2 = 80%). Hospitalization duration was prolonged and use of mechanical ventilation increased. In conclusion, corticosteroid use in subjects with SARS-CoV-2, SARS-CoV, and MERS-CoV infections delayed virus clearing and did not convincingly improve survival, reduce hospitalization duration or ICU admission rate and/or use of mechanical ventilation. There were several adverse effects. Because of a preponderance of observational studies in the dataset and selection and publication biases our conclusions, especially regarding SARS-CoV-2, need confirmation in a randomized clinical trial. In the interim we suggest caution using corticosteroids in persons with COVID-19.

title: Adolescents' Motivations to Engage in Social Distancing During the COVID-19 Pandemic: Associations With Mental and Social Health

text: PURPOSE: Reducing the spread of infection during the COVID-19 pandemic prompted recommendations for individuals to socially distance. Little is known about the extent to which youth are socially distancing, what motivations underlie their social distancing, and how these motivations are connected with amount of social distancing, mental health, and social health. Using a large sample of adolescents from across the United States, this study examined adolescents' motivations for social distancing, their engagement in social distancing, and their mental and social health. METHODS: Data were collected on March 29th and 30th, 2020, two weeks after COVID-19 was declared a national emergency in the United States. The sample consisted of 683 adolescents recruited using social media. A series of multiple linear regressions examined unique associations among adolescents' motivations to engage in social distancing, perceived amount of social distancing, anxiety symptoms, depressive symptoms, burdensomeness, and belongingness. RESULTS: Almost all respondents (98.1%) reported engaging in at least a little social distancing. The most commonly reported motivations for social distancing concerned social responsibility and not wanting others to get sick. Motivations concerning state or city lockdowns, parental rules, and social responsibility were associated with greater social distancing, whereas motivations concerning no alternatives were associated with less social distancing. Specific motivations for social distancing were differentially associated with adolescents' anxiety symptoms, depressive symptoms, burdensomeness, and belongingness. CONCLUSIONS: Understanding adolescents' motivations to engage in social distancing may inform strategies to increase social distancing engagement, reduce pathogen transmission, and identify individual differences in mental and social health during the COVID-19 pandemic.

Use of Renin-Angiotensin System Blockers During the COVID-19 Pandemic: Early Guidance and Evolving Evidence


title: Rapid implementation of COVID-19 tracheostomy simulation training to increase surgeon safety and confidence

text: OBJECTIVE: To determine if rapid implementation of simulation training for anticipated COVID-19 tracheostomy procedures can increase physician confidence regarding procedure competency and use of enhanced personal protective equipment (PPE). METHODS: A brief simulation training exercise was designed in conjunction with the development of a COVID-19 Tracheostomy Protocol. The simulation training focused primarily on provider safety, pre and post-surgical steps and the proper use of enhanced PPE. Simulation training was performed in the simulation lab at the institution over 2 days. Pre and post self-evaluations were measured using standardized clinical competency questionnaires on a 5-point Likert Scale ranging from "No knowledge, unable to perform" up to "Highly knowledgeable and confident, independent." RESULTS: Physicians self-reported a significant increase in knowledge and competency immediately after completing the training exercise. Resident physicians increased from a mean score of 3.00 to 4.67, p-value 0.0041, mean increase 1.67 (CI 95% 0.81 to 2.52). Attending physicians increased from a mean score of 2.89 to 4.67, p-value 0.0002, mean increase 1.78 (CI 95% 1.14 to 2.42). Overall, all participants increased from a mean score of 3.06 to 4.71, p-value 0.0001, mean increase 1.65 (CI 95% 1.24 to 2.05). DISCUSSION: Implementation of this simulation training at our institution resulted in a significant increase in physician confidence regarding the safe performance of tracheostomy surgery in COVID-19 patients. IMPLICATIONS FOR PRACTICE: Adoption of standardized COVID-19 tracheostomy simulation training at centers treating COVID-19 patients may result in improved physician safety and enhanced confidence in anticipation of performing these procedures in real-life scenarios.

text: Lung ultrasound (LU) has rapidly become a tool for assessment of patients stricken by the novel coronavirus 2019 (COVID-19). Over the past two and a half months (January, February, and first half of March 2020) we have used this modality for identification of lung involvement along with pulmonary severity in patients with suspected or documented COVID-19 infection. Use of LU has helped us in clinical decision making and reduced the use of both chest x-rays and computed tomography (CT).


title: Health Belief Model-based Deep Learning Classifiers for Classifying COVID-19 Social Media Content to Examine Public Behaviors towards Physical Distancing

text: BACKGROUND: Public health authorities (PHAs) have been recommending interventions such as physical distancing and face masks, to curtail the transmission of coronavirus disease (COVID-19) within the community. Public perceptions towards such interventions are to be identified so that PHAs can effectively address valid concerns. The Health Belief Model (HBM) has been used to characterize user-generated content from social media during previous outbreaks, to understand health behaviors of people. OBJECTIVE: This study is aimed at developing and evaluating deep learning-based text classification models for classifying social media content posted during the COVID-19 outbreak, using the key four constructs of HBM. We specifically focus on content related to the physical distancing interventions put forth by PHAs. We intend to test the model with a real-world case study. METHODS: The dataset for this study was prepared by analyzing Facebook comments which were posted by the public in response to the COVID-19 posts of three PHAs: Ministry of Health of Singapore (MOH), Centers for Disease Control and Prevention (CDC) and Public Health England (PHE). The comments made in the context of physical distancing were manually classified with a Yes/No flag for each of the four HBM constructs: perceived severity, perceived susceptibility, perceived barriers, and perceived benefits. Using a curated dataset of 16,752 comments, gated recurrent unit (GRU) based recurrent neural network (RNN) models were trained and validated for text classification. Accuracy and binary cross-entropy loss were used for evaluating the model while specificity, sensitivity and balanced accuracy were the test metrics used for evaluating the classification results in the MOH case study. RESULTS: The HBM text classification models achieved mean accuracy rates of 0.92, 0.95, 0.91 and 0.94 for the constructs perceived susceptibility, perceived severity, perceived benefits, and perceived barriers, respectively. In the testing case study with MOH FB comments, specificity was above 96% for all HBM constructs. Sensitivity was 94.3% and 90.9% for perceived severity and perceived benefits while for perceived susceptibility and perceived barriers, it was 79.6% and 81.5%. The classification models were able to accurately predict the trends in the prevalence of the constructs for the examined days in the case study. CONCLUSIONS: The deep learning-based text classifiers developed in this study help in getting an understanding of the public perceptions towards physical distancing, using the four key constructs of HBM. Health officials can make use of the classification model to characterize health behaviors of public through the lens of social media. In future studies, we intend to extend the model for studying public perceptions on other important interventions of PHAs.

title: COVID-19 and Global Economic Growth: Policy Simulations with a Pandemic-Enabled Neoclassical Growth Model

text: During the COVID-19 pandemic of 2019/2020, authorities have used temporary ad-hoc policy measures, such as lockdowns and mass quarantines, to slow its transmission. However, the consequences of widespread use of these unprecedented measures are poorly understood. To contribute to the understanding of the economic and human consequences of such policy measures, we therefore construct a mathematical model of an economy under the impact of a pandemic, select parameter values to represent the global economy under the impact of COVID-19, and perform numerical experiments by simulating a large number of possible policy responses. By varying the starting date of the policy intervention in the simulated scenarios, we find that the most effective policy intervention occurs around the time when the number of active infections is growing at its highest rate -- that is, the results suggest that the most severe measures should only be implemented when the disease is sufficiently spread. The intensity of the intervention, above a certain threshold, does not appear to have a great impact on the outcomes in our simulations, due to the strongly concave relationship that we identify between production shortfall and infection rate reductions. Our experiments further suggest that the intervention should last until after the peak established by the reduced infection rate, which implies that stricter policies should last longer. The model and its implementation, along with the general insights from our policy experiments, may help policymakers design effective emergency policy responses in the face of a serious pandemic, and contribute to our understanding of the relationship between the economic growth and the spread of infectious diseases.


title: Trying Times and Trying Out Solutions: Intimate Partner Violence Screening and Support for Women Veterans During COVID-19

text: Initial reports indicate widespread increases in intimate partner violence (IPV) rates during the coronavirus disease 2019 (COVID-19) pandemic. Women veterans are at particular risk for experiencing IPV, and the COVID-19 pandemic and resulting stay-at-home orders may be exacerbating this risk. IPV screening and intervention are an integral part of the care provided to women veterans in the Veteran's Health Administration (VHA). Current changes in healthcare delivery during COVID-19 may present challenges to the VHA's standard methods of initiating IPV screening and intervention with women veterans. We discuss the potential challenges VHA healthcare providers may be encountering when conducting routine IPV screening during the COVID-19 pandemic and when providing resources and support to women veterans experiencing IPV. We describe solutions to these challenges, including existing efforts led by the VHA IPV Assistance Program (IPVAP) as well as additional potential solutions. New ideas and partnerships will be critical for helping the VHA continue to assist women veterans experiencing IPV as the COVID-19 pandemic evolves. Though our focus is on women veterans and the VHA, the challenges and solutions we discuss are likely applicable to other populations experiencing IPV and other health care systems screening for IPV.

title: Impact of the COVID-19 Pandemic on Quality of Life for Women with Ovarian Cancer

text: PURPOSE: The COVID-19 pandemic has resulted in unprecedented challenges for the oncology community. For people living with cancer, treatments are interrupted, surgeries cancelled and regular oncology evaluations rescheduled. People with cancer and their physicians must balance plausible fears of COVID-19 and cancer treatment with the consequences of delaying cancer care. We aim to evaluate the experience of women with ovarian cancer during the COVID-19 pandemic. METHODS: Women with a current or prior diagnosis of ovarian cancer completed an online survey focusing on treatment interruptions and quality of life (QOL). QOL was measured with the Cancer Worry Scale and Hospital Anxiety and Depression Scale. The survey was distributed through survivor networks and social media. Univariate and multivariable linear regression analysis were utilized to evaluate the effect of participant characteristics on QOL survey scores. RESULTS: Six hundred and three women, from 41 states, visited the survey website between March 30 and April 13, 2020 and 555 (92.0%) completed the survey. The median age was 58 years (range 20-85). Two hundred and seventeen participants (43.3%) were in active treatment at the time of survey completion. One hundred and seventy-five participants (33%) experienced a delay in some component of their cancer care. Ten (26.3%) of the 38 participants scheduled for surgery experienced a delay and 18 (8.3%) of the 217 participants scheuled for nonsurgical cancer treatment. One hundred and thirty-three participants (24.0%) had a delayed physician appointment, 84 (15.1%) laboratory test and 53 (9.6%) cancer related imaging. Among the cohort, 88.6% (489) reported significant cancer worry, 51.4% (285) borderline or abnormal anxiety and 26.5% (147) borderline or abnormal depression. On univariate analysis, age less than 65 years, being scheduled for cancer treatment or cancer surgery, delay in oncology care, self-described as immunocompromised and use of telemedicine were all associated with higher levels of cancer worry. Higher anxiety scores were associated with age less than 65 years and self-described as immunocompromised. Higher depression scores were associated with age less than 65 years, being scheduled for cancer surgery, delay in oncology care, self-described as immunocompromised and use of telemedicine. On multivariable linear regression analysis, age less than 65 and being self-described as immunocompromised were independently predictive of greater cancer worry, anxiety and depression and delay in cancer care was predictive of anxiety and depression. CONCLUSIONS: The COVID-19 crisis is impacting care of ovarian cancer patients: surgeries, treatments, scheduled physician appointments, laboratory tests and imaging are cancelled or delayed. Younger age, presumed immunocompromise and delay in cancer care were associated with significantly higher levels of cancer worry, anxiety and depression. Providers must work with patients to balance competing risks of COVID-19 and cancer, recognizing that communication is a critical clinical tool to improve quality of life in these times.


title: Diagnostic strategies for SARS-CoV-2 infection and interpretation of microbiological results

text: BACKGROUND: To face the current COVID-19 pandemic, diagnostic tools are essential. It is recommended to use real-time RT-PCR for RNA viruses in order (a) to perform a rapid and accurate diagnostic, (b) to guide patient care and management and (c) to guide epidemiological strategies. Further studies are warranted to define the role of serological diagnosis and a possible correlation between serological response and prognosis. OBJECTIVES: The aim was to guide clinical microbiologists in the use of these diagnostic tests and clinicians in the interpretation of their results. SOURCES: A search of literature was performed through PubMed and Google Scholar using the keywords SARS-CoV-2, SARS-CoV-2 molecular diagnosis, SARS-CoV-2 immune response, SARS-CoV-2 serology/antibody testing, coronavirus diagnosis. CONTENT: The present review discusses performances, limitations and use of current and future diagnostic tests for SARS-CoV-2. IMPLICATIONS: Real-time RT-PCR remains the reference method for diagnosis of SARS-CoV-2 infection. On the other hand, notwithstanding its varying sensitivity according to the time of infection, serology represents a valid asset (a) to try to solve possible discrepancies between a highly suggestive clinical and radiological presentation and negative RT-PCR, (b) to solve discrepancies between different PCR assays and (c) for epidemiological purposes.


title: Extrapolation of mortality in COVID-19: Exploring the role of age, sex, co-morbidities and health-care related occupation

text: We used a publicly available data of 44,672 patients reported by China's centre for disease control to study the role of age, sex, co-morbidities and health-care related occupation on COVID-19 mortality. The data is in the form of absolute numbers and proportions. Using the percentages, retrospective synthetic data of 100 survivors and 100 deaths were generated using random number libraries so that proportions of ages, genders, co-morbidities, and occupations were constant as in the original data. Logistic regression of the four predictor factors of age, sex, co-morbidities and occupation revealed that only age and comorbidities significantly affected mortality. Sex and occupation when adjusted for other factors in the equation were not significant predictors of mortality. Age and presence of co-morbidities correlated negatively with survival with co-efficient of -1.23 and -2.33 respectively. Odds ratio (OR) for dying from COVID-19 for every 10-year increase in age was 3.4 compared to the previous band of 10 years. OR for dying of COVID-19 was 10.3 for the presence of any of the co-morbidities. Our findings could help in triaging the patients in the emergency room and emphasize the need to protect the elderly and those with comorbidities from getting exposed.


title: Coordinated responses of academic medical centres to pandemics: Sustaining medical education during COVID-19

text: Background: The Corona Virus Disease-19 (COVID-19) has been declared a pandemic by the World Health Organization (WHO). We state the consolidated and systematic approach for academic medical centres in response to the evolving pandemic outbreaks for sustaining medical education.Discussion: Academic medical centres need to establish a 'COVID-19 response team' in order to make time-sensitive decisions while managing pandemic threats. Major themes of medical education management include leveraging on remote or decentralised modes of medical education delivery, maintaining the integrity of formative and summative assessments while restructuring patient-contact components, and developing action plans for maintenance of essential activities based on pandemic risk alert levels. These core principles must be applied seamlessly across the various fraternities of academic centres: undergraduate education, residency training, continuous professional development and research. Key decisions from the pandemic response teams that help to minimise major disruptions in medical education and to control disease transmissions include: minimising inter-cluster cross contaminations and plans for segregation within and among cohorts; reshuffling academic calendars; postponing or restructuring assessments.Conclusions: While minimising the transmission of the pandemic outbreak within the healthcare establishments is paramount, medical education and research activities cannot come to a standstill each time there is a threat of one.


COVID-19: Act First, Think Later


title: Facing SARS-CoV-2 outbreak in immunotherapy era

text: The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents a worldwide sanitary emergency. The viral biology is only partially known, with some aspects in common with other coronaviruses, and the damage observed in the most severe cases is due to intense inflammation. Immunotherapy restores immunological activity against cancer cells and it has become a standard treatment for several cancers. We carried out an examination of available data on the effects exerted by both SARS-CoV-2 and the most widespread immunotherapy treatments on the immune system in order to hypothesize mechanisms underlying potential and mutual interaction. We provided an analysis of laboratory, clinical and therapeutic data related with severe acute respiratory syndrome coronavirus. We finally focused on implications of immunotherapy treatments in clinical practice.

title: Serological assays for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), March 2020

text: BackgroundThe ongoing coronavirus disease (COVID-19) pandemic has major impacts on health systems, the economy and society. Assessing infection attack rates in the population is critical for estimating disease severity and herd immunity which is needed to calibrate public health interventions. We have previously shown that it is possible to achieve this in real time to impact public health decision making.AimOur objective was to develop and evaluate serological assays applicable in large-scale sero-epidemiological studies.MethodsWe developed an ELISA to detect IgG and IgM antibodies to the receptor-binding domain (RBD) of the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We evaluated its sensitivity and specificity in combination with confirmatory microneutralisation (MN) and 90% plaque reduction neutralisation tests (PRNT90) in 51 sera from 24 patients with virologically confirmed COVID-19 and in age-stratified sera from 200 healthy controls.ResultsIgG and IgM RBD ELISA, MN and PRNT90 were reliably positive after 29 days from illness onset with no detectable cross-reactivity in age-stratified controls. We found that PRNT90 tests were more sensitive in detecting antibody than MN tests carried out with the conventional 100 tissue culture infectious dose challenge. Heparinised plasma appeared to reduce the infectivity of the virus challenge dose and may confound interpretation of neutralisation test.ConclusionUsing IgG ELISA based on the RBD of the spike protein to screen sera for SARS-CoV-2 antibody, followed by confirmation using PRNT90, is a valid approach for large-scale sero-epidemiology studies.


title: Patterns of endoscopy during COVID-19 pandemic: a global survey of interventional inflammatory bowel disease practice

text: Background/Aims: Performance of diagnostic or therapeutic endoscopic procedures in inflammatory bowel disease (IBD) patients can be challenging during a viral pandemic; the main concerns being the safety and protection of patients and health care providers (HCP). The aim of this study is to identify endoscopic practice patterns and outcomes of IBD and coronavirus disease 19 (COVID-19) with a worldwide survey of HCP. Methods: The 20-item survey questionnaire was sent to physician members of the American Society for Gastrointestinal Endoscopy Special Interest Group in Interventional IBD, Chinese IBD Society Endoscopy Interest Group, and the China Crohn's and Colitis Foundation. Results: A total of 141 respondents submitted valid responses. Nighty-five respondents (67.9%) reported that at least 25% of their scheduled emergent endoscopic procedures were canceled or postponed during the pandemic. Fifty-six respondents (40.0%) have performed emergent endoscopy during the pandemic. A few respondents (9/140, 6.4%) estimated that more than 25% of their patients had worsened disease due to delayed or canceled emergent endoscopy procedures. More than 80% of respondents believed that personal protective equipment (PPE) for the endoscopy team, room sterilization, and pre-procedure screening of patients for COVID-19 were necessary. Out of 140 respondents, 16 (11.4%) reported that several of their patients had COVID-19. Eight clinicians (5.7%) reported that they or their endoscopy colleagues developed work-related COVID-19. Conclusions: Cancellation of elective and emergent endoscopy in IBD care during the pandemic was common. Few respondents reported that their patients' disease conditions worsened due to the cancellation of the endoscopy procedure. Most respondents voiced the need for proper PPE during the procedure regardless of patients' COVID-19 status and screening the patients for COVID-19.

title: The impacts of viral inactivating methods on quantitative RT-PCR for COVID-19

text: OBJECTIVE: This paper aims to explore the effect of four virus inactivation methods on the rapid detection results of COVID-19 nucleic acid. METHODS: Collected samples of nasopharyngeal swabs from 2 patients diagnosed with COVID-19 at the First People's Hospital of Zhaoqing City, each of sample was divided into 5 groups (groupAâ¼E): A:Non-inactivated raw sample; B:75 % ethanol inactivation; C:56 â incubation for 30â¯min inactivation; D:65 â incubation for 10â¯min inactivation; E:Pre-inactivation using RNA virus special preservation fluid added into the sampling tube to treated the nasopharyngeal swab sample separately, using real-time fluorescent RT-PCR to detect the N gene of COVID-19 and the ORF1ab gene simultaneously. All the groups are diluted in 1:2, 1:4, 1:8 ratios. The objectives are to compare the effect of the varied inactivation method on CT(Cycle Threshold)results in PCR, conduct correlation and Bland-Altman analysis. RESULTS: For the N gene and ORF1ab gene, the CT values of 4 inactivated and Non-inactivated treatment were correlated (Pï¼0.001). The results of the four treatment methods and specimens without inactivated treatment have shown good consistency. CONCLUSION: The treatment of nasopharyngeal swab specimens using mentioned four inactivated methods had no significant effect on the subsequent detection of the new COVID-19 nucleic acid test. Lab test-persons can flexibly adopt pre-inactivation methods to ensure the accuracy of virus nucleic acid test results, meanwhile guarantee the safety of lab test-persons.

title: Immune checkpoint inhibitors: a physiology-driven approach to the treatment of coronavirus disease 2019

text: Although confirmed cases of the deadly coronavirus disease 2019 (COVID-19) have exceeded 4.7 million globally, scientists are pushing forward with efforts to develop vaccines and treatments in an attempt to slow the pandemic and lessen the disease's damage. Although no proven effective therapies for treating patients with COVID-19 or for managing their complications currently exist, the rapidly expanding knowledge regarding severe acute respiratory syndrome coronavirus 2 and its interplay with hosts provides a significant number of potential drug targets and the potential to repurpose drugs already tested in other diseases. Herein, we report the biological rationale of immune-activating drugs and a brief summary of literature data on the potential therapeutic value of immune checkpoint inhibitors that have been recently tested beyond cancer treatment for their potential to restore cellular immunocompetence.

title: Managing patients with rheumatic diseases during the COVID-19 pandemic: The French Society of Rheumatology answers to most frequently asked questions up to May 2020

text: BACKGROUND: Rheumatologists must contend with COVID-19 pandemic in the management of their patients and many questions have been raised on the use of both anti-inflammatory drugs and disease-modifying anti-rheumatic drugs (DMARD). The French Society of Rheumatology (SFR) selected the most critical ones to the daily practice of a rheumatologist and a group of 10 experts from SFR and Club Rheumatism and Inflammation (CRI) boards proposed responses based on the current knowledge of May 2020. METHODS: Following the availability of the first 18 questions and statements, 1400 individuals consulted the frequently asked questions between the March 31, 2020 and April 12, 2020. As a result, 16 additional questions were forwarded to the SFR, and answered by the board. An additional round of review by email and video conference was organized, which included updates of the previous statements. The scientific relevance of 5 of the questions led to their inclusion in this document. Each response received a final assessment on a scale of 0-10 with 0 meaning no agreement whatsoever and 10 being in complete agreement. The mean values of these votes for each question are presented as the levels of agreement (LoA) at the end of each response. This document was last updated on April 17, 2020. RESULTS: Based on current scientific literature already published, in most circumstances, there is no contraindication to the initiation or continuation of anti-inflammatory drugs as well as DMARDs. If signs suggestive of infection (coronavirus or other) occur, treatments should be discontinued and resumed, if necessary, after 2 weeks without any symptoms. Only, some signals suggest that people taking an immunosuppressive dose of corticosteroid therapy are at greater risk of developing severe COVID-19. Intra-articular injections of glucocorticoids are allowed when there is no reasonable therapeutic alternative, and providing that precautions to protect the patient and the practitioner from viral contamination are adopted, included appropriate information to the patient. CONCLUSIONS: Currently available data on managing patients with rheumatic diseases during the COVID-19 pandemic are reassuring and support continuing or initiating symptomatic as well as specific treatments of these diseases, the main target of their management remaining their appropriate control, even during this pandemic.
