Summary of your 'study carrel' ============================== This is a summary of your Distant Reader 'study carrel'. The Distant Reader harvested & cached your content into a collection/corpus. It then applied sets of natural language processing and text mining against the collection. The results of this process was reduced to a database file -- a 'study carrel'. The study carrel can then be queried, thus bringing light specific characteristics for your collection. These characteristics can help you summarize the collection as well as enumerate things you might want to investigate more closely. This report is a terse narrative report, and when processing is complete you will be linked to a more complete narrative report.

African Americans and Latinos are overrepresented among cases of and deaths from COVID-19, both nationally and in many of the areas hardest hit by the pandemic (2, 3) . We need robust data to guide these efforts, but better information must be coupled with urgent and effective action to decrease exposure, susceptibility, and limitations in health care to achieve the desired results. Achieving the desired population benefit of a SARS-CoV-2 vaccine will require an implementation strategy that addresses the current gaps in overall rates of adult vaccination, as well as specific issues in minority communities.

Methods and Findings: We combined prevalence estimates from a statewide random sample with Indiana vital statistics data of confirmed COVID-19 deaths (4). We accounted for nonresponse by weighting prevalence estimates for age, race (dichotomized as White or non-White), and Hispanic ethnicity to reflect state demographics. We calculated the IFR by age, race, sex, and ethnicity on the basis of the cumulative number of confirmed COVID-19 deaths as of 29 April 2020, divided by the number of infections. Discussion: By using SARS-CoV-2 population prevalence data, we found that the risk for death among infected persons increased with age. doi = 10.7326/m20-5352 id = cord-290070-534936lf author = Bornstein, Sue S. title = The Collision of COVID-19 and the U.S. Health System date = 2020-06-02 keywords = ACP; College summary = In this article, leaders from the American College of Physicians (ACP) discuss key recommendations from ACP''s vision for U.S. health care that can advise how we can act now during the COVID-19 pandemic and in the future in service to patients, our peers, and the profession. As leaders in the American College of Physicians (ACP), we have helped develop ACP''s wide-ranging policies on health care in the United States. The American College of Physicians envisions a health care system where everyone has coverage for and access to the care they need, at a cost they and the country can afford.

These issues have been highlighted and exacerbated by the COVID-19 pandemic, where stakeholders urgently need relevant, accessible, up-to-date, and trustworthy syntheses of high-quality evidence to inform their decisions. Every week, we screen the COVID-19 database produced by the World Health Organization''s International Clinical Trials Registry Platform to identify eligible RCTs. The living mapping produced provides a description of all registered RCTs. The data retrieved and extracted can be explored through interactive data visualizations to identify research gaps and help prioritize and improve future trials. Collectively, COVID-NMA data are used to conduct systematic reviews on specific questions, meta-analyses of individual participant data (IPD), and network meta-analyses and to support the guideline development process and health decision making. doi = 10.7326/m20-5261 id = cord-275946-ofd2ipvs author = Cheng, Matthew P. title = Serodiagnostics for Severe Acute Respiratory Syndrome–Related Coronavirus-2: A Narrative Review date = 2020-06-04 keywords = COVID-19; CoV-2; SARS; antibody summary = Accurate serologic tests to detect host antibodies to severe acute respiratory syndrome–related coronavirus-2 (SARS-CoV-2) will be critical for the public health response to the coronavirus disease 2019 pandemic. This article discusses key use cases for SARS-CoV-2 antibody detection tests and their application to serologic studies, reviews currently available assays, highlights key areas of ongoing research, and proposes potential strategies for test implementation. Appropriately designed seroepidemiologic studies will play an essential part in the public health response to the COVID-19 pandemic by characterizing transmission dynamics, refining disease burden estimates, and providing insight into the kinetics of humoral immunity to SARS-CoV-2. Serologic surveillance studies can also assess the accumulation of persons with antibody responses over time to estimate incidence of SARS-CoV-2 infection (57, 58) and can track age-and jurisdiction-specific disease susceptibility and identify at-risk populations (59) . doi = 10.7326/m20-2854 id = cord-294628-ecg13s7a author = Chia, Ming Li title = Managing COVID-19 in a Novel, Rapidly Deployable Community Isolation Quarantine Facility date = 2020-09-17 keywords = COVID-19; Singapore; patient summary = During the coronavirus disease 2019 (COVID-19) pandemic, Singapore implemented large-scale institutional isolation units called Community Care Facilities (CCFs) to combat the outbreak in the community by housing low-risk COVID-19 patients from April to August 2020. During the coronavirus disease 2019 (COVID-19) pandemic, Singapore implemented large-scale institutional isolation units called Community Care Facilities (CCFs) to combat the outbreak in the community by housing low-risk COVID-19 patients from April to August 2020. In the first month, a total of 3758 patients were admitted to 4 halls, 4929 in-house medical consults occurred, 136 patients were transferred to a hospital, 1 patient died 2 weeks after discharge, and no health care workers became infected. As such, isolation centers called Community Care Facilities (CCFs) were set up throughout the country to house patients with COVID-19 who were at low risk for dying of the disease. doi = 10.7326/m20-4746 id = cord-309650-6xz9gjq0 author = Chou, Roger title = Update Alert 4: Epidemiology of and Risk Factors for Coronavirus Infection in Health Care Workers date = 2020-09-11 keywords = COVID-19; SARS summary = Specific risk factors for SARS-CoV-2 transmission among health care workers in a university hospital Pandemic peak SARS-CoV-2 infection and seroconversion rates in London frontline health-care workers Prevalence of SARS-CoV-2 infection among health care workers in a tertiary community hospital Asymptomatic infection by SARS-CoV-2 in healthcare workers: a study in a large teaching hospital in Wuhan, China Dynamic of SARS-CoV-2 RT-PCR positivity and seroprevalence among high-risk health care workers and hospital staff Risk factors of healthcare workers with Corona Virus Disease 2019: a retrospective cohort study in a designated hospital of Wuhan in China Impact on mental health and perceptions of psychological care among medical and nursing staff in Wuhan during the 2019 Novel Coronavirus Disease outbreak: a cross-sectional study Analysis of the infection status of the health care workers in Wuhan during the COVID-19 outbreak: A cross-sectional study SARS-CoV-2 infection among healthcare workers in a hospital in doi = 10.7326/l20-1134 id = cord-313345-zwe3tmq0 author = Chou, Roger title = Update Alert: Masks for Prevention of Respiratory Virus Infections, Including SARS-CoV-2, in Health Care and Community Settings date = 2020-07-20 keywords = SARS summary = title: Update Alert: Masks for Prevention of Respiratory Virus Infections, Including SARS-CoV-2, in Health Care and Community Settings Masks for prevention of respiratory virus infections, including SARS-CoV-2, in health care and community settings: a living rapid review Facemasks and hand hygiene to prevent influenza transmission in households: a cluster randomized trial Risk factors for SARS infection among hospital healthcare workers in Beijing: a case control study A case-control study on the risk factors of severe acute respiratory syndromes among health care workers Factors associated with transmission of severe acute respiratory syndrome among health-care workers in Singapore Surgical mask vs N95 respirator for preventing influenza among health care workers: a randomized trial A cluster randomized clinical trial comparing fit-tested and non-fit-tested N95 respirators to medical masks to prevent respiratory virus infection in health care workers.

Many medical schools have a "capstone" course in the final weeks before graduation that prepares students for internship, with content geared toward meeting common patient care challenges. The United States could provide loan repayment or other federal payment programs for any senior students willing (and competent, as judged by their medical school) to begin early. The average U.S. medical student graduates with approximately $200 000 of debt (7), so generous repayment programs would be welcome-and fitting-with potentially less bureaucracy than officially hiring students through health care systems short term. Graduate medical education (GME) leaders would need to discuss potentially giving participating students "credit" toward residency completion.

Leaders must communicate current best practices clearly and compassionately, manage expectations, clarify work hours, and provide sufficient resources and effective personal protective equipment. Leaders should aim for work schedules that promote physical resilience by enabling adequate sleep and providing access to call rooms for hospital-based clinicians working long or multiple shifts. Health care organizations can provide information on managing stress, reducing burnout, and identifying mental health professionals available to support clinicians (3). Examples of settings for such sharing include the American College of Physicians Physician Well-Being and Discussion Forum (5), the Society of General Internal Medicine GIMConnect (6) , and the American Medical Association Physician Health (7) resources that members can access.

After adjustment for differences in participant characteristics ( Table 3) , factors that were independently associated with vaccine hesitancy (response of "no" or "not sure") include younger age (<60 years), Black race, educational attainment of less than a college degree, and not receiving an influenza vaccine in the prior year. We found several independent predictors of being hesitant to be vaccinated against COVID-19; the strongest were lower educational attainment, Black race, not having had a recent influenza vaccination, and perceived personal risk for coronavirus, consistent with the findings of a national survey conducted by RTI (20) . doi = 10.7326/m20-3569 id = cord-280672-6x968dwk author = Fisman, David N. title = Age Is Just a Number: A Critically Important Number for COVID-19 Case Fatality date = 2020-07-22 keywords = CFR summary = In their article, Sudharsanan and colleagues show the importance of adjusting for the age distribution of cases of coronavirus disease 2019 before doing cross-country comparisons of case-fatality rates. Failure to recognize younger, milder cases diminishes the denominator in case-fatality ratio (CFR) calculations (that is, deaths/cases), so between-country differences in age structure explain some fraction of observed between-country variation in epidemic severity and case-fatality. In their analysis, the authors show that adjusting for differences in population age structure substantially reduces the observed differences between country-specific CFRs. To further explore the effect of age distribution on CFR, we can take the standardization approach used by Sudharsanan and colleagues and turn it on its head. When the reported CFR for February 2020 in mainland China (2.3%) is age-standardized using population pyramids from other countries (7), standardization to a country with a younger population structure, such as Indonesia, markedly reduces observed CFR (1.7%), whereas adjustment to a country with an older population, such as Italy, increases the CFR (3.9%). doi = 10.7326/m20-4048 id = cord-339509-4ezt6o0o author = Fox, Sharon E. title = Cardiac Endotheliitis and Multisystem Inflammatory Syndrome After COVID-19 date = 2020-07-29 keywords = COVID-19; figure summary = In addition, a multisystem inflammatory syndrome (MIS) similar to Kawasaki disease has been increasingly reported in association with COVID-19 in children and young adults (3) (4) (5) . Objective: To provide what we believe to be the first report on the pathologic findings of vasculitis of the small vessels of the heart, which likely represents MIS, leading to death in a young adult after presumed resolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Gross abnormalities noted at autopsy (4 hours after death) were conjunctival injection, enlarged cervical and mediastinal lymph nodes, and vascular thrombi with focal surrounding hemorrhage in the left lower lung, which probably contributed to illness but were not likely the primary cause of death. The clinical picture in this adult patient of sudden lymphadenopathy and parotitis combined with small-vessel cardiac vasculitis after COVID-19 is strongly suggestive of a similar systemic inflammatory process.

We have learned the value of finding meaning in times of intense grief and sorrow-a new skill for many clinicians outside palliative care. With that in mind, we share a foundational set of principles to use as guidance for building internal support for the trauma caused by the pandem-ic: looking past the illness, fostering community, promoting vulnerability, and establishing boundaries and limitations. In palliative care, these challenges bring us together and we make time to talk about them in groups; 1 example is weekly Bereavement Rounds to share grief about the death of our patients.

The signs and symptoms of coronavirus disease 2019 (COVID-19) are largely indistinguishable from those of other respiratory virus infections. Case detection is still primarily focused on identifying patients with fever, cough, or shortness of breath; this focus leads to underestimation of the number of infected persons, overestimation of the mortality rate, and ongoing spread of disease. To cause a nosocomial outbreak, it will take just 1 patient with occult COVID-19 who is hospitalized, tests negative for influenza virus, and is taken off precautions despite persistent respiratory symptoms. But if we are frank about the morbidity and mortality of all respiratory viruses, including SARS-CoV-2, this is the best thing we can do for our patients and colleagues regardless of COVID-19. doi = 10.7326/m20-0751 id = cord-337482-imxkpfrn author = Koplan, Jeffrey title = Maxims for a Pandemic: Time, Distance, and Data date = 2020-10-27 keywords = Alagoz; covid-19 summary = In their article, Alagoz and colleagues explored the effect of COVID-19–related public health mandates in 3 U.S. locations.

I n their article, Alagoz and colleagues explored the effect of coronavirus disease 2019 (COVID-19)-related public health mandates in 3 U.S. locations-Dane County, Wisconsin; the Milwaukee metropolitan area; and New York City-using agent-based simulation models (1) . They modeled variations in adherence to social distancing mandates, time of intervention, and population density. Alagoz and colleagues'' study provides an opportunity to pause and assess how modeling can and should inform COVID-19 decision making.

We examine the historical arc of the 1918 influenza pandemic, focusing on black Americans and showing the complex, sometimes surprising ways it triggered particular responses both within a minority community and in wider racial, sociopolitical, and public health structures. Although the influenza pandemic does not reveal ready associations between deleterious social, cultural, and economic conditions and poor outcomes (aside from higher case-fatality rate) for black Americans, the gaps in historical documentation may reflect inherent disparities and consequences of limited racial/ethnic data collection. doi = 10.7326/m20-2223 id = cord-335003-7ae0galy author = Kussmaul, William G. title = COVID-19 and Angiotensin-Converting Enzyme Inhibitor/Angiotensin-Receptor Blocker Therapy date = 2020-05-15 keywords = COVID-19 summary = Mackey and colleagues reported a systematic review that found high-certainty evidence that angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers are not associated with greater illness severity in patients with COVID-19. The authors present data from 3 studies that found, with moderate certainty of evidence, no relationship of ACEI or ARB use with testing positive for the virus or becoming ill from it. On the basis of further data from 14 observational studies encompassing more than 23 000 adults with COVID-19, they found high-certainty evidence that the drugs are not associated with greater illness severity. As a result of this progression from fear and theory through data and multiple analyses from different continents, we now have reasonable reassurance that drugs that alter the renin-angiotensin system (RAS) do not pose substantial threats as either COVID-19 risk factors or severity multipliers.

Traditional FDA approval typically supports clinical adoption of new standards of care because approval reflects a determination that a product''s benefits outweigh its risks on the basis of a demonstration of safety and substantial evidence of effectiveness, a higher threshold than that required for an EUA. Despite concerns about whether that approval was warranted, given the data existing when the EUA was granted and consensus guidelines recommending remdesivir''s use, failing to offer the drug (when available) might have been viewed as improperly withholding an intervention from which severely ill patients could expect to benefit. In contrast, if an EUA is based on weak evidence, such as observational data or uncontrolled trials-as in the case of convalescent plasma-institutions and clinicians can reasonably decline to offer the product without wronging eligible patients (8) . doi = 10.7326/m20-6703 id = cord-300474-r5gms09p author = Mackey, Katherine title = Update Alert 2: Risks and Impact of Angiotensin-Converting Enzyme Inhibitors or Angiotensin-Receptor Blockers on SARS-CoV-2 Infection in Adults date = 2020-07-23 keywords = covid-19 summary = title: Update Alert 2: Risks and Impact of Angiotensin-Converting Enzyme Inhibitors or Angiotensin-Receptor Blockers on SARS-CoV-2 Infection in Adults Results of 3 new meta-analysis (2-4) evaluating the association of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin-receptor blocker (ARB) use with coronavirus disease 2019 (COVID-19) illness severity are consistent with the findings that we reported in the original manuscript.

Treatment of individual patients with COVID-19 with convalescent plasma outside such trials is also now permitted through U.S. Food and Drug Administration Emergency Use Authorization. Here, members of the National Institutes of Health COVID-19 Treatment Guidelines Panel provide their views regarding use of convalescent plasma for treating COVID-19. In March 2020, the FDA authorized expanded access to convalescent plasma for treating severe or life-threatening COVID-19 under individual-patient emergency Investigational New Drug applications. Given the lack of data from properly powered RCTs, and the need to inform regulatory decision making regarding continued access to convalescent plasma, both the FDA and the Mayo Clinic performed retrospective, indirect evaluations of efficacy by using EAP data, hypothesizing that patients who received plasma units with higher titers of neutralizing antibodies would have better clinical outcomes. doi = 10.7326/m20-6448 id = cord-301183-k39e12cq author = Pham, Tho D. title = SARS-CoV-2 RNAemia in a Healthy Blood Donor 40 Days After Respiratory Illness Resolution date = 2020-07-17 keywords = SARS summary = title: SARS-CoV-2 RNAemia in a Healthy Blood Donor 40 Days After Respiratory Illness Resolution than 1 month after symptom resolution is concerning in light of current guidelines, which do not recommend SARS-CoV-2 screening in the general allogeneic donor population (5) . In this case, plasma viral RNA was reproducibly detected at a time point that exceeded recommendations for deferral based on time since symptom resolution (14 days). Of importance, these results are unlikely to be false-positive given that 2 different regions of the SARS-CoV-2 genome were detected in separate specimens collected on the day of donation and that quality control passed on all runs, including the absence of amplification in the negative controls.

CONCLUSION: Active surveillance and surge testing were used to detect multiple cases of asymptomatic and symptomatic SARS-CoV-2 infection in homeless shelters. Surge testing was initiated on 30 March 2020 (and continued through 24 April) in collaboration with Public Health-Seattle & King County''s Communicable Disease Epidemiology Team to conduct contact tracing at 6 shelters where cases of SARS-CoV-2 were previously detected ( Figure 2 ). We calculated the test positivity rate of SARS-CoV-2 infection at shelters by dividing the number of positive cases by the total number of participant encounters in the study period. Overall, 2% of participant encounters involved positive SARS-CoV-2 results, with most cases detected through surge testing events. doi = 10.7326/m20-3799 id = cord-323054-m8hkj1dm author = Schwartz, Rachel title = Addressing Postpandemic Clinician Mental Health: A Narrative Review and Conceptual Framework date = 2020-08-21 keywords = COVID-19; care; clinician; health summary = In a narrative review of 96 articles addressing clinician mental health in COVID-19 and prior pandemics, 7 themes emerged: 1) the need for resilience and stress reduction training; 2) providing for clinicians'' basic needs (food, drink, adequate rest, quarantine-appropriate housing, transportation, child care, personal protective equipment); 3) the importance of specialized training for pandemic-induced changes in job roles; 4) recognition and clear communication from leadership; 5) acknowledgment of and strategies for addressing moral injury; 6) the need for peer and social support interventions; and 7) normalization and provision of mental health support programs. Seven themes, and associated interventions, emerged from the literature (Figure) : 1) the need for resilience and stress reduction training; 2) providing for clinicians'' basic needs (food, drink, adequate rest, quarantine-appropriate housing, transportation, child care, PPE); 3) the importance of specialized training for pandemic-induced changes in job roles; 4) recognition and clear communication from leadership; 5) acknowledgment of and strategies for addressing moral injury; 6) the need for peer and social support interventions and; 7) normalization and provision of mental health support programs. doi = 10.7326/m20-4199 id = cord-301852-9nza3po0 author = Sears, David title = Occupational Health: A Key to the Control of COVID-19 in Correctional Facilities date = 2020-07-27 keywords = COVID-19 summary = Coronavirus disease 2019 has swept through prisons in much the same way it has nursing homes: after being introduced by staff or newly arrived residents, it spreads efficiently, including to many with medical vulnerabilities. The authors believe that ensuring community-standard occupational health for correctional staff during COVID-19 will protect prison residents, staff, and their communities. As COVID-19 transmission continues unabated in these settings, protecting the health and safety of correctional workers is a moral imperative and an underappreciated requirement to mitigate the pandemic''s effect on incarcerated persons and surrounding communities. Although occupational health interventions should focus primarily on correctional officers given their numbers and close, sustained contact with incarcerated persons, interventions should be adapted to reduce risk for infection for all staff. To protect correctional staff and ensure that community standards of care are afforded to incarcerated populations during the COVID-19 pandemic, prisons must: Ensuring community-standard occupational health for correctional staff during COVID-19 will protect us all. doi = 10.7326/m20-4543 id = cord-325643-nszsf0nu author = Tan, Benjamin Y.Q. title = Psychological Impact of the COVID-19 Pandemic on Health Care Workers in Singapore date = 2020-04-06 keywords = IES summary = The prevalence of anxiety was higher among nonmedical health care workers than medical personnel (20.7% versus 10.8%; adjusted prevalence ratio, 1.85 [95% CI, 1.15 to 2.99]; P = 0.011), after adjustment for age, sex, ethnicity, marital status, survey completion date, and presence of comorbid conditions. Similarly, higher mean DASS-21 anxiety and stress subscale scores and higher IES-R total and subscale scores were observed in nonmedical health care workers ( Table 2) . Discussion: Overall mean DASS-21 and IES-R scores among health care workers were lower than those in the published literature from previous disease outbreaks, such as the severe acute respiratory syndrome (SARS). In conclusion, our study highlights that nonmedical health care personnel are at highest risk for psychological distress during the COVID-19 outbreak.

In light of evidence that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can survive on surfaces for up to 3 days (5), along with studies demonstrating that viral shedding contaminates over 80% of the interior of hospital rooms (6) and aerosolization of SARS-CoV-2 causes extensive surface contamination (7), it is now more urgent than ever to emphasize the importance of environmental cleaning. Cleaning staff have been whittled down by 25% during this time, and more than one third of hospitals have disbanded their own EVS teams to outsource this work to contractors, shedding valuable institutional experience while exacerbating high turnover and inadequate training (1). To thoroughly disinfect a hospital room, EVS workers need sufficient time, proper technique, and effective tools. doi = 10.7326/m20-2237 id = cord-284694-bk6bnox0 author = Wang, Changsong title = Cytokine Levels in the Body Fluids of a Patient With COVID-19 and Acute Respiratory Distress Syndrome: A Case Report date = 2020-05-12 keywords = level summary = title: Cytokine Levels in the Body Fluids of a Patient With COVID-19 and Acute Respiratory Distress Syndrome: A Case Report In addition, the time from symptom onset to confirmation of COVID-19 diagnosis was relatively long, the patient''s hospital course was longer, and we wonder whether this long duration of viral replication contributed to the high cytokine levels we measured. As a result, we wonder whether tocilizumab would have affected the IL-6 levels we observed and whether it might have improved this patient''s disease course, especially because others have reported that as COVID-19 progresses to its middle and late stages, the expression of inflammatory cytokines is related to the severity of the disease (4). On the basis of our experience, we encourage additional research to determine whether inflammatory cytokines in the lungs predict the clinical course of COVID-19 and whether these cytokines should be a target for intervention and treatment. doi = 10.7326/l20-0354 id = cord-267124-8efdzlc0 author = Wichmann, Dominic title = Autopsy Findings and Venous Thromboembolism in Patients With COVID-19: A Prospective Cohort Study date = 2020-05-06 keywords = COVID-19; RNA; SARS; patient summary = In response to the pandemic spread of SARS-CoV-2, the authorities of the German federal state of Hamburg ordered mandatory autopsies in all patients dying with a diagnosis of COVID-19 confirmed by polymerase chain reaction (PCR). During autopsy, tissue samples for histology were taken from the following organs: heart, lungs, liver, kidneys, spleen, pancreas, brain, prostate and testes (in males), ovaries (in females), small bowel, saphenous vein, common carotid artery, pharynx, and muscle. In this autopsy study of 12 consecutive patients who died of COVID-19, we found a high incidence of deep venous thrombosis (58%). In studies that examined deceased patients with COVID-19 without relying on autopsy, no increased rates of pulmonary embolism were observed clinically. To our knowledge, only 3 case reports have been published on patients with COVID-19 who have undergone complete autopsy and a few more in which only lung tissue was examined (7, 8) . doi = 10.7326/m20-2003 id = cord-270970-9gtnsyts author = Wolf, Michael S. title = Awareness, Attitudes, and Actions Related to COVID-19 Among Adults With Chronic Conditions at the Onset of the U.S. Outbreak: A Cross-sectional Survey date = 2020-04-09 keywords = COVID-19; health; table summary = In multivariable analyses, participants who were black, were living below the poverty level, and had low health literacy were more likely to be less worried about COVID-19, to not believe that they would become infected, and to feel less prepared for an outbreak. We did a time-sensitive study among higher-risk, older adults living with 1 or more chronic conditions to determine their current awareness of COVID-19, their perception of the seriousness of its threat, their level of worry and concern related to contracting the virus, whether it is affecting their daily routine or existing plans, how prepared they feel to handle an outbreak, and their confidence in the federal government response. In our study, disparities by race, socioeconomic status, and health literacy were not reflected in ratings of the seriousness of the COVID-19 threat, demonstrated knowledge of its symptom presentation or general means to prevent it, or reported changes to daily routines and plans. doi = 10.7326/m20-1239 id = cord-253196-et1ekgdl author = Yazdany, Jinoos title = Use of Hydroxychloroquine and Chloroquine During the COVID-19 Pandemic: What Every Clinician Should Know date = 2020-03-31 keywords = COVID-19; HCQ summary = Two medications often used for treatment of immune-mediated conditions, hydroxychloroquine and chloroquine, have recently attracted widespread interest as potential therapies for coronavirus disease 2019. The antimalarials hydroxychloroquine (HCQ) and chloroquine (CQ) have demonstrated antiviral activity against severe acute respiratory syndromecoronavirus 2 (SARS-CoV-2) in vitro and in small, poorly controlled or uncontrolled clinical studies (1) (2) (3) . Here, we try to provide guidance regarding clinical decision making both for patients with COVID-19 and those with immune-mediated conditions, such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), and strategies to mitigate further harm to these patients. At this time of crisis, it is our ethical obligation as physicians and researchers to organize and refer patients to expedited, well-performed randomized trials that can clarify if, when, and for whom antimalarial medications are helpful in COVID-19.
