This decentralized trial is a Phase 2, 1:1 randomized, double-blind, superiority, placebo-controlled study in an anticipated 100 non-hospitalized highly symptomatic adult participants with long COVID. It seeks to determine the efficacy, safety, and tolerability of 15 days of Paxlovid (nirmatrelvir/ritonavir), an anti-viral agent, compared with placebo plus ritonavir. The hypothesis is that viral persistence contributes to long COVID in some patients and nirmatrelvir/ritonavir compared with placebo/ritonavir can improve general health status in participants with long COVID. The study will also seek immune signatures associated with treatment response (overseen by Professor Akiko Iwasaki). The decentralized study does not require site visits, and participants in all 48 states including the District of Columbia, who meet entry criteria can enroll. It is designed to make it convenient to participate. The study drugs will be delivered to the participant's designated address. Long COVID is also known as post-acute sequelae of SARS-CoV-2 (PASC).

The COVID-19 pandemic has resulted in significant loss of life and suffering with total case and death counts increasing daily, particularly with the emergence of the delta variant. COVID-19 vaccines have proven highly effective in preventing severe illness, hospitalization, and death. Nevertheless, according to VA data sources, only 56% of all U.S. Veterans have been vaccinated to date, largely owing to vaccine hesitancy and lack of access to vaccination. Thus, there is a critical need for evidence-based interventions to increase COVID-19 vaccine acceptance and access among Veterans, many of whom are vulnerable to poor outcomes of COVID-19. The overall goal of this study is to increase COVID-19 vaccination in Veterans of VISNs 16 and 21 who remain unvaccinated either because of vaccine hesitancy or lack of access to COVID-19 vaccine. Specifically, the investigators will test a COVID-19 Vaccine Acceptance Intervention (Motivational Interviewing) plus Implementation Facilitation.

Little is known regarding the effect of antenatal COVID-19 on pregnancy outcomes. The purpose of this study is to determine of COVID-19 alters histopathology and gene expression of the placenta, as evidenced by analysis at time of delivery. The analysis will aim to identify whether resulting abnormal placental pathology or altered metabolism is associated with severity of symptoms (specifically pneumonia, or need for admission), gestational age at onset, and/or placenta efficiency. Histological and gene expression analysis of the placental post-delivery will determine if COVID-19 alters overall placental structure, vascularization, and/or the transcriptome.

We are conducting a research study at the VA hospital in Bedford, MA to learn more about how a multisensor rapid health assessment device, MouthLab, can help predict or anticipate future health complications in patients with underline conditions after contracting COVID-19. The device was created by a health technology and digital medicine company called Aidar Health, Inc. MouthLab is a non-invasive, hand-held device that works like a breathalyzer. An individual breathes into the device for 60 seconds and the MouthLab gathers more than 10 vital health parameters like temperature, heart rate, SpO2, ECG, and basic lung functions. Participation in the study will last for 6 months, and the purpose is to gather health information from people who have been previously hospitalized with COVID-19. We will use the data to develop an algorithm that predicts future complications of COVID-19, especially among patients with complex conditions (i.e., heart failure, chronic kidney disease, diabetes, hypertension, asthma, chronic obstructive pulmonary disease), and enables early intervention.

After a 30-year decline, heart disease is projected to increase up to 18% by 2030. Participation rates in cardiac rehabilitation remain extremely low and hopeless individuals are less likely to participate. This innovative study has the potential to advance science, improve patient care, and improve patient outcomes by demonstrating the effectiveness of the Heart Up! program to increase physical activity and reduce hopelessness in patients with heart disease. Hopelessness is associated with a 3.4 times increased risk of mortality or nonfatal myocardial infarction in patients with ischemic heart disease (IHD), independent of depression. Hopelessness has been identified in 27-52% of patients with IHD and can persist for up to 12 months after hospital discharge. Hopelessness, a negative outlook and sense of helplessness toward the future, can be a temporary response to an event (state) or a habitual outlook (trait). Hopelessness is associated with decreased physical functioning and lower physical activity (PA) levels in individuals with IHD. While research has investigated strategies to increase PA among IHD patients in general, the study team is the only group to design an intervention to promote PA specifically in hopeless IHD patients. The purpose of this randomized controlled trial is to establish the effectiveness of our 6-week mHealth intervention (Heart Up!) to promote increased PA in hopeless patients with IHD. A total of 225 hopeless IHD patients will be enrolled from a large community teaching hospital in the Midwest. Patients will be randomized (75 per group) to one of three groups: 1) motivational social support (MSS) from a nurse, 2) MSS from a nurse with additional significant other support (SOS), or 3) attention control (AC). It is hypothesized that 1) The MSS with SOS group will have the greatest increase in average minutes of moderate to vigorous PA per day at 8 and 24 weeks as compared to the MSS only or AC groups; 2) Greater increase in minutes of moderate to vigorous PA per day will be associated with decreased state hopelessness levels from baseline to weeks 8 and 24; and 3) Increased social support and increased motivation will mediate the effects of Heart Up! on a greater increase in moderate to vigorous PA at 8 and 24 weeks. The findings from this study could transform care for IHD patients who are hopeless by promoting self-management of important PA goals that can contribute to better health outcomes.

Since its initial outbreak in late 2019, coronavirus disease 2019 (COVID-19) caused by the novel coronavirus SARS-CoV-2 has ravaged the globe, causing illness characterized by inflammation and impaired oxygen levels. As a particularly vulnerable group, pregnant women have had a heightened prevalence and severity of infection. In this context, a new population of children has emerged who were exposed to maternal COVID-19 in the womb. As maternal diseases during pregnancy may impact the health of offspring over the life course, health outcomes among these individuals must be urgently evaluated. In the current study, the investigators will leverage a perinatal biorepository comprised of pregnant women with and without COVID-19 to delineate the metabolic and cardiovascular risk profiles of these offspring. This work stands to benefit the burgeoning population of children exposed to COVID-19 in the womb and to deepen the mechanistic understanding of developmental origins of cardiometabolic disease with respect to maternal infections.

The value of clinical cardiopulmonary exercise testing (CPET) within healthcare settings has been established in the last decade. CPET methods remain highly relevant in the COVID-19 endemic phase and should be used to assess those recovering from COVID-19 (SARS-CoV-2) infection. This diagnostic tool could play an integral role in disease prognostication and evaluate the integrative response to incremental exercise. Date from such assessments can enable practitioners to characterise cardio-respiratory fitness and identify reasons for physical impairment or abnormal cardio-respiratory function. More than 50% of patients admitted to hospital will experience cardiorespiratory issues and significant morbidity during their recovery and will require significant rehabilitative support. In this context, measurements obtained from an assessment of cardio-respiratory responses to physiological stress could provide insight regarding the integrity of the pulmonary-vascular interface and characterisation of any impairment or abnormal cardio-respiratory function. Current approaches to rehabilitation are being developed on existing knowledge from Severe Acute Respiratory Syndrome (SARS) and Acute Respiratory Distress Syndrome (ARDS) related illness. These provide important insight but do not provide insight into the novel challenges provided by COVID-19.
