Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.

Mental health vulnerability due to stress is increased in People of African Descent (PADs) in America due to disproportionate effects of racism, poverty, education, and criminal justice sentencing. Various meditation and mindfulness approaches have provided evidence of measured reductions in multiple negative dimensions of stress. However, the majority of these studies do not have an adequate representation of PADs or other marginalized groups and are not designed to be culturally relevant or community based. Music has been shown to alleviate multiple symptoms of stress and has been shown to be a preferred and effective support for meditation and mindfulness. However, its role in stress management in PADs engaged in meditation or mindfulness is seldom studied. This study aims to evaluate the effects of a virtual, community-based music mindfulness program on stress management in PAD community members with anxiety and depression during COVID19. 2b. Social Music Study: Investigators will assess the neural mechanisms of feelings of subjective connectedness during communal music listening and creating between dyads of subjects who are both familiar and unfamiliar with each other.

The purpose of the study is to learn about the safety of PF-07817883 and how PF-07817883 is processed in the body of adult participants. These participants will have different degrees of loss of liver function. Participants with mild, moderate, severe or no loss of liver function will be enrolled in 4 groups. This study is seeking participants who: - are male or female of 18- 75 years of age - either have different amounts of damage to liver function or for one of the groups, no damage - willing to follow the requirements of the study including stay at clinic for 6 nights and 7 days About, 6-8 participants will be enrolled in group 1 (participants without loss of liver function) and group 3 (participants with moderate loss of liver function). In group 4 (participants with severe loss of function), around 4 to 8 participants will be enrolled. Participants in group 2 (mild loss of function) will only be enrolled after review of the data from groups 3 and 4. If participants consent to participate in the study, it may take up to 4 weeks to complete all the tests to confirm if they are eligible to participate in the study. If they seem to be eligible for the study, participants will be admitted to a clinic research unit (CRU) at least 12 hours before dosing. On Day 1, participants will receive a single dose of study medicine (Day 1). A series of blood samples will be collected before and after dosing. Participants will be discharged from the CRU on Day 6. A follow-up phone call (on CRU visit, if needed), will occur 28-35 days after dosing. The whole study will last for a minimum of 5 weeks and a maximum of 10 weeks.

The COVID-induced fibrotic lung damage continues long after viral infection has subsided and is exhibited by severe respiratory pathology and concomitant symptoms. The long-lasting sequelae in patients who have recovered from severe COVID indicate that there is a 30% chance of developing a persistent respiratory system pathology and a 10% chance of developing a severe pathology. The symptoms of lung fibrosis include a severe disruption of respiration, reduction of exercise tolerance, and concomitant development of persistent fibrotic lung damage. This study intends to evaluate benefits of a combination of VL-P22 and VL-PX10 in Covid-19 patients exhibiting pulmonary fibrosis.

SARS-CoV-2 spreads rapidly throughout the world. A large epidemic would seriously challenge the available hospital capacity, and this would be augmented by infection of healthcare workers (HCW). Strategies to prevent infection and disease severity of HCW are, therefore, desperately needed to safeguard continuous patient care. Bacille Calmette-Guérin (BCG) is a vaccine against tuberculosis, with protective non-specific effects against other respiratory tract infections in in vitro and in vivo studies, and reported morbidity and mortality reductions as high as 70%. Furthermore, in our preliminary analysis, areas with existing BCG vaccination programs appear to have lower incidence and mortality from COVID191. The investigators hypothesize that BCG vaccination can reduce HCW infection and disease severity during the epidemic phase of SARS-CoV-2.

Nursing homes are ground zero for the COVID-19 pandemic. Nursing homes are ill-equipped for the pandemic; though facilities are required to have infection control staff, only 3% have taken a basic infection control course. Significant research has focused on infection control in the acute care setting. However, little is known about the implementation of practices and effective interventions in long-term care facilities.The investigators propose an intervention utilizing Project ECHO, an evidence-based telehealth model, to connect Penn State University experts with remote nursing home staff and administrators to proactively support evidence-based infection control guideline implementation. Our study seeks to answer the critical research question of how evidence-based infection control guidelines can be implemented effectively in nursing homes
