Response: Early reports and observations in the COVID-19 pandemic found that patients recovering from mild to severe forms of COVID-19 illness had a higher prevalence of cardiac injury in comparison with what historically has been seen and reported with other viruses. This cardiac injury, categorized as inflammatory heart disease, could have serious implications, including a risk for exercise-triggered sudden cardiac death, for athletes and highly active people who have had prior COVID-19 illness and who return to intensive exercise activity with unknowing subclinical cardiac injury.
To address these concerns in COVID positive athletes, the ACC generated return to play cardiac screening recommendations (troponin blood test, ECG, resting echocardiogram) for all competitive athletes after COVID-19 infection prior to resumption of competitive and intensive sport activity. The professional leagues were among the first organizations to return to full-scale sport activity in the setting of the pandemic, and they uniformly adopted and implemented the ACC return to play screening recommendations for all athletes that tested positive for COVID-19. The leagues recognized that there was value in collaborating and formally analyzing their pooled cardiac data, not only for league athlete health and safety purposes, but also to share broadly this information to add to the growing body of knowledge about the virus.

MedicalResearch.com: What is the background for this study?
Response: Recent media polls continue to show that Black Americans are less likely to intend to get the COVID-19 vaccine than White Americans, and initial state data show a similar racial/ethnic disparity in vaccination rates. Initial uptake of the vaccine has been significantly affected by inequities in vaccine access and supply. In addition to these challenges, other factors contribute to hesitancy around vaccination, including self-perceived risk of infection, trust in the vaccine itself, trust in healthcare systems, healthcare providers, and policymakers who support the vaccine, and trust in the pharmaceutical industry and clinical research. In this study, we conducted a survey of a nationally representative sample of 207 Black Americans in late 2020, after initial COVID-19 vaccine effectiveness and safety data were released to the public. We also did in-depth interviews with a subsample of those surveyed who said that they would not get vaccinated. In addition, we engaged with a stakeholder advisory committee comprised of individuals who represent different subgroups and organizations in Black communities in the U.S., in order to discuss the results and make recommendations for policies to increase COVID-19 vaccination among Black Americans.

MedicalResearch.com: What is the background for this study?
Response: The science on school transmissions of COVID is becoming clearer all the time in its conclusion that there is little to no transmission in school environments as long as reasonable precautions are taken. Yet one recent study got a lot of attention for claiming that states that allowed their schools to remain open in the early days of the pandemic saw more cases. That study did not control for several important factors that might explain this association, so our study aimed to correct that work.

MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by postural orthostatic tachycardia syndrome? Is it more common in patients who have incompletely recovered from a COVID-19 infection?
Response: Postural Orthostatic Tachycardia Syndrome (POTS) is a, complex multisystem clinical syndrome Patients experience a wide spectrum of symptoms of varying severity, which are often debilitating. Upon assuming an upright standing position from being supine, patients experience an increase in heart rate by 30 beats per minute (bpm) from supine position, This is often accompanied by lightheadedness, palpitations, dyspnea, mental clouding (“brain fog”), headaches.
POTS can occur after infections as it thought to be triggered by the immune system . The hypothesis is that when the body is fighting an infection some of the antibodies it produces can attack our regulatory systems that control heart rate and blood pressure.
We are seeing an increase in POTS cases occurring after COVID-19 infection. These patient are referred to as the “long haulers”
These long haulers have elevated heart rate, fatigue, brain fog and shortness of breath with activity consistent with POTS.
We are seeing that COVID-19 is another infection that can lead to POTS.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Understanding the proportion of COVID-19 cases that become symptomatic, as well as the extent to which people without symptoms contribute to COVID-19 transmission, has important public health implications.
However, changes in PCR testing capacity over time have made these quantities hard to estimate precisely.
We used a model that incorporates daily changes in PCR testing capacity, cases, and serology to precisely estimate the proportion of cases that were symptomatic in New York City during the initial wave of the outbreak.
Only 1 in 7 to 1 in 5 cases were symptomatic.
Furthermore, non-symptomatic cases of the virus (this includes people who are either pre-symptomatic or asymptomatic) substantially contribute to community transmission, making up at least 50% of the driving force of SARS-CoV-2 infection.

MedicalResearch.com: What is the background for this study?
Response: Similar to past pandemics, prior studies and news articles have highlighted the disproportionate impact of COVID-19 mortality in marginalized populations, especially Black Americans. Rather than biological differences, other factors like neighborhood conditions, educational attainment, economic stability, healthcare access, and social contexts have been hypothesized to influence the racial disparities.
Using county-level data, we sought to quantitatively determine how these factors, collectively referred to as social determinants of health, impact COVID-19 mortality in Black Americans.

MedicalResearch.com: What is the background for this study? How does this test differ from other tests for COVID-19?
Response: We know COVID-19 causes a wide spectrum of disease, and that while many develop only mild uncomplicated illness, others develop severe respiratory failure, multi-organ failure and death. These patients often require prolonged hospitalization, ICU level care and even mechanical intubation for respiratory support. However, we still do not have a great way to identify which patients are likely to develop severe disease. We felt it was important to have a test that could act as sort of a ‘biomarker’ that we could measure early in COVID-19 patients and would help predict which patients would develop severe disease. From prior work, we knew that mitochondrial DNA, which are proinflammatory molecules that are released into the circulation from damaged organs could be this such ‘biomarker’. So, we measured the levels of mitochondrial DNA circulating in the plasma of patients with COVID-19 at the time they first presented to the hospital. Then we investigated if higher levels of mitochondrial DNA indeed predict the development of more severe disease.
Currently there are no ‘biomarker’ tests specific for COVID-19. We do currently measure levels of other markers in the hospital that we feel might help us assess overall how sick patients may be, but these are very non-specific and assess only level of inflammation. This test instead can measure level of tissue injury.

MedicalResearch.com: What is the background for this study?
Response: In the course of our clinical work, we have noticed a predominance of musculoskeletal complaints among some of COVID-19 patients who are otherwise clinically well, and a small subset of them who develop a viral arthralgia (joint pains) sometimes occurring separately from the onset of acute respiratory symptoms. Besides a few isolated case reports, there was not much described about COVID-19 associated viral arthralgia in the literature.
Clinicians are well aware of the need to test for COVID-19 when patients present with cough or shortness of breath. However, when they present as joint pains without any respiratory symptoms, a diagnosis of COVID-19 could easily be missed. Due to overlapping clinical features like low platelet count and elevated liver enzymes, they could easily be misdiagnosed as having other vector-borne infections such as dengue fever, if clinicians do not have a high clinical suspicion of COVID-19. Hence we decided to describe the epidemiology and various presentations of musculoskeletal manifestations of COVID-19 in our cohort of patients.

MedicalResearch.com: What is the background for this study?
Response: Patients with COVID-19 frequently need to come to the intensive care unit (ICU), where we use mechanical ventilation to support their lungs as they get over the intense inflammation caused by the virus. During the first wave of the virus we noted that a lot of our patients appeared to be developing secondary infections (infections they didn’t have when they came into the ICU).
We therefore rolled out a rapid diagnostic test for these secondary bacterial infections that we had developed previously, and this study reports the use of this diagnostic and also describes the types of bacteria seen. To see if the increase in secondary infections was due to COVID specifically, we compared them to patients who were managed in the same ICU but who did not have COVID.

MedicalResearch.com: What is the background for this study?
Response: Patient surveys have shown that most people prefer to die at home at the end-of-life. However, during the initial wave of the COVID-19 pandemic, anecdotal evidence from our colleagues and findings from a prior study published in the Journal of the American Geriatrics Society suggested that majority of COVID-19 decedents died in a medical facility. However, less is known about care intensity at the end-of-life according to place of death among patients who died of COVID-19. Therefore, we characterized end-of-life care by place of death among COVID-19 decedents at Mass General Brigham (MGB), the largest health system in Massachusetts.

Response: Universal screening for SARS-CoV-2 infection on Labor and Delivery (L&D) units is a critical strategy to manage patient and health worker safety, especially in a vulnerable high-prevalence community. We describe the results of a SARS-CoV-2 universal screening program at the L&D Unit at Elmhurst Hospital in Queens, NY, a 545-bed public hospital serving a diverse, largely immigrant and low-income patient population and an epicenter of the global pandemic.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Driving in a car with ride-share or car-pool is a widely prevalent social interaction. The study aimed to address the airflows inside cars in various window open/closed configurations using computer simulations, and also looking into the possibility of movement of aerosol-type of particles from one occupant to other.
The main findings are that opening windows provides a likely benefit to reduce the potentially pathogenic aerosols inside the cabin. Generally, more windows the better, but at the least it would be advisable to have one rear side window and one frontside window open.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Measures to control the spread of COVID-19 included stay-at-home mandates and business lockdown policies which resulted in many facing a loss of income or employment and more time spent isolated at home. Life stressors (like job loss and social isolation) have been shown to be associated with increased drinking at unhealthy levels. Those with a history of mental health problems may be even more at risk.
We aimed to see if binge drinking (5 or more drinks [male] or 4 or more drinks [female] in one session) and levels of alcohol consumption among binge drinkers were impacted by these pandemic-related factors. We found that increased time spent at home (in weeks) was associated with a 19% increase in the odds of binge drinking and binge drinkers with a previous diagnosis of depression and current depression symptoms (during the early months of the pandemic) had a 237% greater odds of drinking more alcohol (vs drinking the same amount) compared to those with no history and current symptoms of depression.
