Gut microbiome dysbiosis has been noted in patients with Post-acute sequelae (PASC) of Severe Acute Respiratory Syndrome-CoronaVirus -2 (SARS-CoV-2). A study performed at Columbia found that plasma levels of the short chain fatty acid (SCFA), butyric acid, remained lower in people with Neuropsychiatric PASC (NP-PASC) than in people with PASC after SAR-CoV-2 infection. Synbiotics improve SCFA levels and are well-tolerated in the general population but have not been studied among people with PASC in the United States. The purpose of this pilot study is to characterize changes in plasma SCFA levels and gut microbiome after treatment with synbiotics and placebo in people with NP-PASC. The intervention will be a mixture of the prebiotic resistant starch and the probiotic Bifidobacterium adolescentis in-vivo selection 1 strain (iVS-1). The placebo will be Maltodextrin.

Rationale: Hyper-inflammatory responses seen in acute COVID-19 are also a feature of long covid, a condition of long-term consequences that are persisting or appearing after initial infection and recovery from acute COVID-19. Long-standing, often disabling symptoms are common in long covid and can be highly varied. Common symptoms include fatigue, brain fog, muscle and chest pain, migraines, shortness of breath, anosmia, muscle weakness, and cognitive dysfunction. 35% of post-COVID patients were found to have decreased kidney function at 6 months post-discharge. In this study, we will evaluate the effect of dietary interventions in long covid patients. The dietary interventions are aimed at lowering blood glucose levels, and raising blood BHB levels. The dietary plan will recommend a low-carbohydrate diet including the avoidance of foods containing sugars and starch, while simultaneously increasing the consumption of healthy fats and sources of protein. The dietary interventions are supported by the consumption of a medical food that delivers exogenous BHB in order to raise blood BHB levels without the necessity of adhering to a strict ketogenic diet which would be difficult to implement and typically requires strict medical supervision. Intervention: Dietary intervention with Ketocitra versus control arm (no intervention) in a 1:1 ratio Objectives: The hypothesis of this study is that low-carbohydrate dietary interventions leading to lowering of blood glucose and raising of blood BHB in addition to standard therapy will lead to faster recovery and amelioration of symptoms in long covid compared to those treated with standard therapy alone. Study population: Subjects with a history of COVID-19 at least 2 months ago and with at least 2 neurological and/or symptoms that are typical for long covid that either started at COVID-19 infection and are ongoing at time of study entry Study methodology: Prospective and interventional randomized controlled pilot study Study arms: Dietary intervention (including medical food) arm versus control arm Study endpoints: The primary endpoint is the feasibility, safety and tolerability of dietary intervention.

The goal of this observational study is to evaluate new non-invasive passive surveillance technologies, Level 42 AI imPulse™ Una and TOR devices for the detection of COVID-19, Flu, and/or RSV in asymptomatic and symptomatic individuals over age of 18 undergoing COVID-19, Flu, and/or RSV screening and testing at BAMC Ft Sam Houston, TX; with and without COVID-19, Flu, and/or RSV. The hypotheses are: (H1) The imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic COVID-19 carrier versus those not infected compared to gold standard RT-PCR. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their usability between the devices. (H2) Identify if the imPulseTM Una and the imPulseTM TOR e-stethoscopes have at least a similar discriminative and detection ability among symptomatic and asymptomatic Respiratory Syncytial Virus (RSV), Influenza and Long COVID carriers versus those not infected compared to gold standard Rapid RSV and Flu Antigen Tests, or RT-PCR and molecular assays. We will operationalize and deploy both the imPulseTM Una and imPulseTM TOR e-stethoscope into DoD use-cases and compare their captured traces in the early identification of disease/illness analyzed by the devices built in algorithms. (H3) In the mid to long-term, this approach will also be explored as a diagnostic system to explore pursue the physical (structural and mechanical) properties of cells and tissues that maintain normal cell behavior (motility, growth, apoptosis), and the critical importance of the ability of cells to sense and respond to mechanical stresses, which will be operationally critical for assessment of both traumatic and unconventional exposures in austere environments. Participants will: - Be consented; - Be screened for COVID-19, Flu, and/or RSV symptoms according to BAMC's current screening procedures; - Have study data collected; - Complete a symptoms questionnaire; - imPulseTM Una and TOR e-stethoscopes examination will be conducted; - Participants will be compensated for completing all study requirements. (Active-Duty personnel must complete the study procedures while off-duty in order to receive compensation.)

COVID-19 infection during pregnancy is associated with increased risk of pre-eclampsia, preterm birth and stillbirth. Pregnant people with COVID-19 have a higher rate of ICU admission and intubation than those who are not pregnant. COVID-19 vaccine is recommended before pregnancy and during pregnancy to decrease these risks. Despite the benefits of COVID-19 vaccination, only 71% of pregnant women were vaccinated for COVID-19 as of June 2022 (most prior to pregnancy), with a much lower rate of 58% among non-Hispanic Black women. An effective intervention is needed to improve COVID vaccination rates for pregnant people overall. In this study, the investigators will perform a randomized controlled trial aimed at practice change in obstetricians' offices, with an overall goal of increasing maternal COVID-19 vaccination rates.

The overall purpose of this observational cohort study is to characterize COVID-specific immune responses to SARS-CoV-2 exposure or COVID vaccination in a real-world setting. Participants will be asked to provide blood samples (either a normal venous blood draw, a few drops of blood obtained with a small finger-stick device, or both), as well as saliva or nasal swab sample at a series of visits. Subjects will receive results of the testing that is approved for routine clinical use (i.e., their AditxtScore), while residual samples from each visit will be stored for future testing. These efforts will support ongoing AditxtScore test development and enhance the effectiveness of its interpretation - aiding efforts to maximize benefits of clinical laboratory testing in the pandemic response.

There is a pressing need to increase capacity to treat PTSD related to or exacerbated by the COVID-19 pandemic. Texting-based therapy holds promise to increase capacity and reduce barriers to delivering evidence-based treatments (EBTs), but ongoing engagement in digital mental health interventions is low. This study will compare a texting-based EBT for PTSD to culturally-informed texting-based treatment for PTSD as usual, and it will also compare a unique incentive strategy to typical platform reminders aimed to prevent early discontinuation in therapy. This online study is open to individuals who live in 18 different states.

Background: Coronavirus 2019 (COVID-19, or SARS-CoV-2) is a serious public health problem, and genetics may play a role in how serious the illness becomes in certain people. Genes are the instructions that our body uses to grow and develop. Variations in our genes can cause medical conditions and may be the reason why some people get sicker than others. Objective: This study aims to learn more about the genetic contributions to the severity of COVID-19. We hope to use this information to develop therapies that reduce the severity of COVID-19 symptoms in some people. Eligibility: Anyone located in the United States who has tested positive for SARS-CoV-2 infection may be eligible to join (including NIH staff). Design: Participants will complete a questionnaire about their health history and COVID-19 symptoms. Participants will give a blood or saliva sample. It will be about 2 tablespoons of blood, or we will send a saliva collection kit. Researchers will use this blood or saliva sample to study the participant s DNA. The data about participants genes will be stored in a large database. The database will be shared with other qualified researchers who are trying to learn about COVID-19. Participants names and other personal details will not be shared. Instead, the data will be labeled with a code. Participants may be contacted by study team members for up to a year after they join the study.

The purpose of this study is to understand how COVID-19 affects people's ability to work and to calculate the costs associated with loss of work. The study compares two groups of participants who are confirmed to have mild-to moderated COVID-19 and who have high chances of the disease becoming severe. The two groups are: People who took the antiviral medication nirmatrelvir-ritonavir (also called Paxlovid) People who were eligible to receive antiviral medication but did not receive any. The participants will be selected from various health databases in the US between June 2021 and December 2022. The main goals are: To look at the characteristics of both groups of participants with COVID-19. To measure how much work these participants missed, including days off and sick leave, and the costs associated with this work loss. To compare work loss and costs between the two groups of participants, considering differences in their clinical and demographic characteristics. The study will evaluate at least 30 days of data from participants after they are confirmed to have COVID-19

The goal of this clinical trial is to test two investigational COVID-19 booster vaccines, called CoTend-s3BXBB and CoTend-BXBB, in healthy volunteers ages 40-64. The CoTend-s3BXBB vaccine includes a component called "s3", which was designed to improve the body's response to the vaccine. CoTend-BXBB is the same vaccine without s3. The main questions the study aims to answer are: 1) Is the investigational vaccine safe? 2) Does "s3" lead to bigger, broader, and longer-lasting responses to the vaccine? 5 different doses of the vaccines will be studied. Participants will receive a single dose of either CoTend-s3BXBB, CoTend-BXBB, or placebo. Participants will be monitored for side effects. Saliva, nasal, and blood samples will be collected and immune responses to the vaccine will be measured.
