Effectiveness of Transcranial Direct Current in Patients With Persistent COVID-19 With Headaches and Chronic Pain.

This study aims to verify the efficacy/effectiveness of treatment with transcranial direct current stimulation (TDCS) in patients with Long Covid who experience headaches, migraines, and chronic pain, such as arthralgia and myalgia, as well as sleep problems. Transcranial direct current stimulation is used in the field of Physiotherapy and Rehabilitation, with results that have proven to be effective for treating patients suffering from symptoms like migraines, headaches, chronic pain, fibromyalgia, or chronic neuropathic pain and insomnia. As you can see, in the case of patients with Long Covid, we find several of these symptoms, so it is suggested that if transcranial direct current therapy (TDCS) gives such good results in relieving these symptoms, why couldn't it give such good results and help just as much in patients with Long Covid, since many of the symptoms are the same, even if the origin or cause is different.

HH-120 Nasal Spray for Post-exposure Prevention of SARS-CoV-2

This study will assess the efficacy of HH-120 nasal spray in participants for the post-exposure prevention of SARS-CoV-2.

COVID-19 Experiences in the SELF Cohort

Background: COVID-19 affected African Americans more than Whites. African Americans, especially women, have had higher rates of COVID-19 infections compared to Whites. They are also more likely to go to the hospital or die of this disease. Many researchers who looked into these issues lacked background data on the people they studied. SELF is a 10-year study of fibroids in African American women aged 23-35. Researchers already have a lot of data on these women. Asking how COVID-19 affected them can add context other studies lack. Objective: To describe the impact of the COVID-19 pandemic on young African American women and their families. Eligibility: Participants must be enrolled in SELF (Study of Environment, Lifestyle, and Fibroids). Design: Researchers will invite all women enrolled in SELF to participate in this natural history study. Participants will complete one questionnaire. They will answer the questions online. They may also choose to get a paper copy sent by mail. The survey will take no more than 15-20 minutes. All questions will relate to COVID-19. Participants will be asked if they had COVID-19. They will be asked if family, friends, or members of their community did. They will answer questions about their vaccine status and access to health care services. Participants will also answer questions about how the pandemic affected their lives. They will be asked about their job and if finding childcare was a challenge. They will be asked about money problems and how they coped. They will be asked about sleep problems and emotional distress. Participants will get a $30 gift card after they finish the survey. ...

Flu COVID Vaccine Views

This study addresses a critical evidence gap relevant to implementation strategies for combination vaccines in health care settings. This study will specifically investigate healthcare worker (HCWs) attitudes around and willingness to receive combination influenza/COVID-19 vaccines. Findings will identify determinants of hesitancy and acceptance among HCWs and support effective rollout strategies and communication approaches. Cross-sectional surveys and qualitative interviews will be conducted with healthcare workers to characterize HCW willingness to be vaccinated and to identify demographic, attitudinal, and structural predictors of vaccination.

Identification and Characterization of SARS-CoV-2 Specific CD8 T Cells in Humans

Background: The higher death rate from COVID-19 in the older population is associated with low CD8 T cell counts in the blood. Researchers want to learn the status of CD8 T cells specific to SARS-CoV-2 and their changes with aging and in COVID-19. This may help to identify why COVID-19 is particularly lethal in the elderly and help to create an effective vaccine against SARS-CoV-2 in the elderly. Objective: To identify SARS-CoV-2 specific CD8 T cells in humans, and to determine their quantity and quality in people who have recovered from COVID-19. Eligibility: Maryland residents age 18 and older who have tested positive for and recovered from COVID-19. Design: Participants will be screened by phone. They must be able to provide a copy of their positive COVID-19 test result. Participants will visit the NIA/Clinical Research Unit. The visit will take about 1 hour. Laboratory tests showing a positive COVID-19 result will be verified. Participants vital signs will be checked. This will include blood pressure, temperature, pulse, and respiration. Height and weight will be measured. Participants will have a medical history and medicine review. They will complete a COVID-19 questionnaire. Participants will have blood drawn. They will give a urine sample. Participants will give a saliva sample. They will rinse their mouth with water. After about 3 minutes, they will let saliva pool in the base of their mouth and then spit into a sterile container. Participants may be asked if they would be willing to return for optional visits at about 4 months and 1 year later. They will repeat the same laboratory sampling performed at the first visit. ...

A Phase 2b, Randomized, Double-blind, Active-controlled Study of Single Dose CVXGA Intranasal COVID-19 Vaccine in Adults

The purpose of this trial is to assess the safety and relative efficacy of CVXGA (CVXGA50), a KP.2 containing vaccine, compared to COMIRNATY® (COVID-19 Vaccine, mRNA; 2024-2025 Formula), a currently approved COVID-19 vaccine in the prevention of symptomatic, RT-PCR-confirmed SARS-CoV-2 infection. The trial will enroll up to 434 healthy participants.

A Study to Evaluate VXA-CoV2-3.3 COVID-19 Vaccine Against Currently Approved/Authorized mRNA COVID-19 Injectable Booster Vaccine in Adults Previously Immunized Against COVID-19 Infection

The primary objective of the study is to determine the relative efficacy of the investigational oral severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) vaccine tablet VXA-CoV2-3.3 compared to a currently recommended vaccine for the prevention of symptomatic Coronavirus Disease 2019 (COVID-19). In order to represent a more recently circulating SARS-CoV-2 variant, the main study endpoints will now evaluate the VXA-CoV2-3.3 (KP.2 strain) vaccine, and not the VXA-CoV2-3.1 (XBB.1.5 strain) vaccine.

Longitudinal Deep Phenotyping of Central Mechanisms in Dysosmia: A Pilot Study Using Electrobulbogram (EBG), Functional MRI (fMRI), and Diffusion-Weighted Imaging (DWI)

Background: Loss of the sense of smell can seriously affect a person's quality of life. The ability to smell can be damaged by many factors, including illnesses, injuries, and exposure to toxic chemicals. The effects can vary, including complete loss of smell, partial loss, and parosomia, which is when things smell differently than they should. Objective: To study how brain function changes in people with different types of smell disorders. Also, to look at how smell loss affects quality of life over time. Eligibility: People aged 18 years or older with a disorder that affects their sense of smell. Healthy volunteers are also needed. Design: Participants will have 5 study visits over 1 year. They will have various tests and procedures: Smell tests. They will have several tests that involve smelling different items and answering questions. Questionnaires. They will answer questions about their health, mood, sense of smell, and daily habits. Magnetic resonance imaging (MRI) scans. They will lie on a bed that slides into a tube. Padding will hold their head still. They will smell different odors while in the scanner. Electrobulbogram (EBG). They will wear a soft cap with sensors that measure brain activity. They will smell different odors while wearing the cap. Nasal endoscopy. A flexible tube will be inserted into a nostril to view the inside of the nose. Biopsy. A numbing substance will be sprayed into the nose. Then a scissor-like tool will be used to collect a sample of tissue from one or both nasal passages. Samples of blood, urine, and nasal fluid will be taken.

The aim of this possible study is to identify if SARS-CoV-2 can be found in the tear film and conjunctiva of a patient with COVID-19.

REVIVe: Frailty, Rehabilitation, and Outcomes in Critically Ill Adult and Pediatric Survivors of COVID-19 or ARI

Background: Many adults and some children with COVID-19 or acute respiratory infection become critically ill and need advanced life support in the Intensive Care Unit (ICU). Frailty is a medical condition of reduced function and health. Adults with frailty have a lower chance of surviving critical illness. The investigators are still learning about critically ill adults with COVID-19 or acute respiratory infection, and do not have much information on how frailty affects outcomes in critically ill children, with or without COVID-19 or acute respiratory infection. Rehabilitation can help survivors of COVID-19 or acute respiratory infection by improving strength and improve quality of life (QOL). Objectives: The main goal of this research study is to see if patients with frailty have a lower chance of surviving COVID-19 or acute respiratory infection critical illness and more health problems after survival than patients without frailty. The investigators will also study the types of rehabilitation received by patients with COVID-19 or acute respiratory infection. Methods: The investigators will include adults and children with COVID-19 or acute respiratory infection who are admitted to the ICUs that participate in the study. The investigators will gather data about each patient, including before and during their illness. Outcomes: The investigators will collect level of frailty, function, and types of therapy, or rehabilitation received by patients. In adults, the investigators are most interested in learning if frailty influences mortality, or death. In children, the investigators are most interested in whether children with COVID-19 or acute respiratory infection critical illness are more likely to develop frailty. The investigators will also study post-hospital discharge location in survivors (e.g., home, rehabilitation). Relevance: The COVID-19 pandemic is a global public health crisis. It is critical to understand how COVID-19 and other acute respiratory infection critical illness affects groups of people who are at higher risk, and the impact on outcomes that are important to patients, like functioning and QOL. The results will help policy makers plan post-hospital services for survivors, help healthcare workers understand the importance of rehabilitation practice for patients with COVID-19 or acute respiratory infection, and help researchers develop treatments to improve QOL after COVID-19 or acute respiratory infection.

Study to Monitor the Occurrence of Viral Variants in Patients With Compromised Immune Systems Being Treated for COVID-19

Sotrovimab binds to a conserved epitope on the severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2 spike protein outside the receptor-binding motif and has been shown to reduce the risk of hospitalization and/or death when administered as early treatment in non-hospitalized patients that are at risk for progression to severe disease. Immunocompromised (IC) patients are prioritized to receive early treatment for COVID-19 as they are at high risk of disease progression, and because of their potential for prolonged viral shedding and the resulting increased risk of emergent viral mutations and potential onward community transmission. This genomic surveillance study will aim to describe changes in the SARS-CoV-2 spike protein observed in IC participants receiving sotrovimab as standard of clinical care in sentinel sites at a national level to assess potential emergence of viral variants.

Effectiveness of mRNA-1273 Variant-Containing Vaccine Formulation Against Severe Outcomes in Adults Aged 50-64 Years Without Risk Factors for Severe COVID-19

The purpose of this pragmatic randomized trial is to evaluate the vaccine effectiveness of the COVID-19 vaccine, mRNA-1273, in adults aged 50-64 years without known risk factors for severe COVID-19 infection. Participants will be randomized 1:1 to either COVID-19 vaccine or no COVID-19 vaccine.

Comparison of Pulmonary Telerehabilitation and Physical Activity Recommendations in Patients With Post Covid Fibrosis

Rehabilitation plays a very important role in the management of patients with COVID-19, focusing on respiratory and motor functions, and therefore the importance of establishing treatment strategies to ensure optimal recovery of these patients has been emphasized. It has been stated that physical activity recommendations should be clarified for the management of symptoms associated with prolonged COVID-19 Syndrome and for the continuation of activities of daily living. It has been stated that after COVID-19 pneumonia, it is necessary to evaluate the physical functions of patients with long-term follow-up and to establish rehabilitation programs. The importance of being included in the rehabilitation program was emphasized, especially for patients with lung fibrosis. The primary aim of this study was to compare the effects of pulmonary telerehabilitation and physical activity recommendations on exercise capacity and peripheral muscle strength in patients with pulmonary fibrosis due to COVID-19. The secondary aim of this study is to compare the effects of pulmonary telerehabilitation and physical activity recommendations on symptoms, activity and participation in patients with pulmonary fibrosis due to COVID-19.

Determinants of SARS (Severe Acute Respiratory Syndrome)-COV2 (COVID-19) Persistence After Convalescence

The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.

Effect of a Social-Support-Based Educational Intervention on COVID-19-Related Anxiety and Perceived Social Support in Pregnant Women: A Randomized Pretest-Posttest Controlled Trial

The goal of this randomized controlled trial is to learn if a spouse-inclusive, social-support-based educational intervention can reduce COVID-19-related anxiety and improve perceived social support in pregnant women during public health emergencies. The main questions it aims to answer are: * Does the intervention reduce COVID-19-related anxiety in pregnant women compared to routine care? * Does the intervention improve perceived social support across its five dimensions (emotional, informational, tangible, affection, and positive social interaction)? Researchers will compare a group of pregnant women and their spouses who receive the seven-session educational program to a control group that receives only routine prenatal care, to see if the intervention reduces anxiety and enhances social support. Participants will: * Attend seven weekly 60-minute face-to-face sessions together with their spouses, which include group discussions, lectures, and Q\&A * Receive supplementary virtual messages (motivational and educational content) between sessions * Complete questionnaires measuring COVID-19 anxiety and perceived social support at three time points: before the intervention, immediately after, and one month later

Equity Evaluation of Fact Boxes on Informed COVID-19 and Influenza Vaccination Decisions - Study Protocol

The study aims to evaluate whether evidence-based fact boxes on COVID-19 and influenza vaccination contribute to the decision making of laypeople from different social backgrounds in different educational settings (e.g. medical practices, outreach work). Furthermore, the study will investigate whether evidence-based fact boxes can contribute to more equitable health care by improving shared decision-making.

Randomized Double-Blind Placebo-Controlled Trial EValuating Baricitinib on PERSistent NEurologic and Cardiopulmonary Symptoms of Long COVID

The overarching goal of this study is to determine if baricitinib, as compared to placebo, will improve neurocognitive function, along with measures of physical function, quality of life, post-exertional malaise, effect of breathlessness on daily activities, post-COVID-19 symptom burden, and biomarkers of inflammation and viral measures, in participants with Long COVID.

Strategies and Treatments for Respiratory Infections & Viral Emergencies (STRIVE): Shionogi Protease Inhibitor (Ensitrelvir)

Treatments are needed to improve outcomes among patients hospitalized for COVID-19, including direct-acting antiviral (DAA) agents to mitigate the pathology driven by ongoing viral replication. This trial will evaluate S-217622 (ensitrelvir), an anti-SARS-CoV2 3C-like protease inhibitor (PI) developed by Shionogi \&; Co. Ltd. The study design is a randomized, placebo-controlled, multi-center international clinical trial that will evaluate the clinical efficacy of ensitrelvir when given in addition to standard of care (SOC) for inpatients with COVID-19. The SOC will be determined by local established guidelines and may include additional DAA (e.g., remdesivir) and immunomodulatory treatment strategies. Certain SOC treatments will be pre-specified prior to randomization.

Immunogenicity and Safety of a Single Dose of mRNA SARS-CoV-2 Vaccine in Chinese Adults With Hybrid Immunity

This is a multicentre post-marketing cohort study to evaluate the immunogenicity and safety of a single dose of mRNA SARS-CoV-2 vaccine SYS6006 in Chinese adults predominantly with hybrid immunity. A total of 2,052 adults aged 18 years and older who received one dose of SYS6006 were monitored for serious adverse events (SAEs) for 6 months. The first 60 participants comprised an immunogenicity subgroup, with blood samples collected before vaccination and at day 14, month 3, and month 6 post-vaccination to assess humoral and cellular immune responses.

Mitoquinone/Mitoquinol Mesylate as Oral and Safe Postexposure Prophylaxis for Covid-19

Adults who do not have major health, kidney, gastrointestinal disease will be randomized to receive oral mitoquinone/mitoquinol mesylate (Mito-MES) versus placebo to prevent the development and progression of COVID-19 after high-risk exposure to a person with confirmed SARS-CoV-2 infection.

Cohort of Patients Infected With SARS-CoV2 (COVID-19) or Suspected of Being

On 17th March 2020, 198 193 confirmed cases (7 730 in France) of COVID-19 infections and 7 854 deaths (175 in France) have been reported from 8th December 2019 in 157 countries. The rapid increase in cases on french territory has led to the transition of France to level 3 of the epidemic on 14th March 2020. The natural history of the disease is still poorly understood, especially prognostic factors, which are crucial for the best medical care of patients in times of epidemics, when hospital capacities are under pressure. A better knowledge of natural history, of prognostic factors, the development and validation of new diagnostic tests, the evaluation of medical care, will lead to a better medical care of patients infected with COVID-19.

A Longitudinal Study of COVID-19 Sequelae and Immunity

Background: COVID-19 is a disease caused by the SARS-CoV-2 virus. It infects the respiratory tract. Some people who get COVID-19 have only mild symptoms. But for others, infection leads to pneumonia, respiratory failure, and, in some cases, death. Researchers want to learn more about any effects that may persist after people recover from COVID-19. Objective: To learn about any long-term medical problems that people who have recovered from COVID-19 might have, and whether they develop an immune response to SARS-CoV-2 that provides protection against reinfection. Eligibility: People age 18 and older who have recovered from documented COVID-19 or were in close contact with someone who had COVID-19 but did not get the infection Design: Participants will be screened over 2 visits. During visit 1, they will answer questions about any symptoms they are having and will be tested for SARS-CoV-2 infection which will involve a nasal swab sample or other FDA approved test. If the test is negative, they will proceed to the second visit, which will include: Physical examination Medical history Mental health interview (which may be recorded if the participant agrees) Chest x-ray (for recovered COVID-19 participants only) Blood and urine tests Pregnancy test (if needed) Lung function test (for recovered COVID-19 participants only) 6-minute walk test (for recovered COVID-19 participants only) Questionnaires about their general and mental health Leukapheresis to collect white blood cells (optional). Participants will be put into 1 of 2 groups: the COVID-19 group or the close contact group. Participants will have study visits every 6 months for 3 years. They will repeat some of the screening tests. Participants in the COVID-19 group may have visits more often if they develop symptoms that suggest re-infection with SARS-CoV-2.
