The Impact of the COVID-19 Pandemic on Eating Behavior and Weight Change

Background: The indirect effects of the COVID-19 pandemic on mental health are of increasing concern. Perceived stress can lead to binge eating and weight gain. Researchers want to learn more about the relationship between eating behavior and the pandemic. Objective: To study how the stress of the COVID-19 pandemic is affecting eating behaviors and weight. Eligibility: English-speaking adults ages 18 and older who have access to a computer or smartphone connected to the internet. Design: This is an online study. Participants will answer surveys through the study website. Participants will complete a one-time survey. It will ask about their experiences throughout the COVID-19 pandemic, their socioeconomic standing, their mental and physical health, and their eating habits. They will have the option to repeat the survey once a month for the next 12 months. This will show changes in their thoughts and behaviors over time. They will provide their email address to get survey links. Participants will also have the option to complete a 2-minute survey on their smartphone. They will complete the survey daily for 7 days in a row. It will ask about their stress and eating behavior in real time, in their home environment. They will provide their phone number to get survey links via text message. If a participant has taken part in a previous NIH study on the Phoenix AZ campus, they will be asked to share their first and last name, date of birth, and email address. This information will be used to connect data from this study to their past data. Participation is typically 25 minutes but may last up to 1 year....

Safety and Immunogenicity Study of a SARS-CoV-2 (COVID-19) Variant Vaccine (mRNA-1273.351) in Naïve and Previously Vaccinated Adults

This is a phase 1, open-label, randomized clinical trial in males and non-pregnant females, 18 years of age and older, who are in good health, have no known history of COVID-19 or SARS-CoV-2 infection, and meet all other eligibility criteria. This clinical trial is designed to assess the safety, reactogenicity and immunogenicity of mRNA-1273.351 manufactured by ModernaTX, Inc, given in vaccination schedules alone, sequentially, or coadministered with mRNA-1273. mRNA-1273.351 is a novel lipid nanoparticle (LNP)-encapsulated mRNA-based vaccine that encodes for a full-length, prefusion stabilized S protein of the SARS-CoV-2 B.1.351 variant. Enrollment will occur at approximately five domestic clinical research sites. This study includes two cohorts. Cohort 1 will provide rapid information about the immunogenicity of mRNA-1273.351 in a previously vaccinated group. This cohort can inform near term public health decisions if the variant virus becomes more widespread. Cohort 2 will evaluate different strategies for generation of cross protective immune responses in a naïve population. This cohort will take longer to provide information on the immunogenicity of mRNA-1273.351, but is important to inform future public health strategies. Cohort 1 will include approximately 60 subjects 18 years of age and older who received two vaccinations of mRNA-1273 at dosages of 50 mcg, 100 mcg, or 250 mcg in the Phase 1 clinical trial (DMID 20-0003). Subjects in Cohort 1 will receive a single intramuscular (IM) injection of the designated vaccine and will be followed through 12 months after vaccination. Follow-up visits will occur on Days 8, 15, and 29, as well as 3, 6, and 12 months after the vaccination. Cohort 2 will include approximately 150 participants 18 through 55 years of age who have not received a COVID-19 vaccine, have no known history of COVID-19 or SARS-CoV-2 infection, and do not have underlying conditions that are associated with an increased risk of severe illness from SARS-CoV-2 infection. They will be randomly assigned to one of 8 treatment arms and will receive 2 or 3 IM injections of the vaccine and followed through 12 months after the last vaccination. Follow-up visits will occur 7, 14, and 28 days after each vaccination, as well as 3, 6 and 12 months post the last vaccination. The primary objective is to evaluate the safety and reactogenicity of mRNA-1273 and mRNA-1273.351 vaccines, in naïve and previously vaccinated individuals.

Hydroxychloroquine (HCQ) as Post Exposure Prophylaxis (PEP) for Prevention of COVID-19

COVID-19 affected more than 9 million of people with more than 130 thousand death in India. If adequate preventive and therapeutic measures are not taken, India has very high risk of affecting million of more people with high mortality because of the large population along with very high population density. At present there are no definitive therapeutic drugs or vaccine available for the treatment and prevention of SARS-CoV-2 infection. Symptomatic and supportive care are being given to COVID-19 cases along with isolation and quarantine measure are being taken for the suspected individual at risk for COVID-19 to limit the spread of the SARS-CoV-2 infection . Among the all the drugs being used for the treatment of COVID-19, hydroxychloroquine (HCQ), has given some rays of hope to battle against this deadly pandemic. HCQ has some anti viral effect against SARS-CoV in vitro. HCQ is quite safe and being used in rheumatology patients for lifelong without much side effect, so it allow for higher dose without any significant side effects and drug-drug interaction. Recently published clinical trial suggested HCQ can be used for the therapeutic purpose of the SARS-CoV-2 infection and many governments have endorsed that due to lack of any other better alternative drugs. Indian council of medical research (ICMR) has advised for HCQ prophylaxis for the people who are at risk for developing SARS-CoV-2 infection, all asymptomatic health care workers involved in taking care of suspected or confirmed COVID-19 cases and all asymptomatic household contacts of laboratory confirmed COVID-19 cases. With this encouragement an open level clinical trial was conducted on HCQ as post exposure prophylaxis (PEP) for the prevention of COVID-19 in asymptomatic high risk house hold contact of the laboratory confirmed COVID-19 cases. The result was very promising showing absolute risk reduction of around 9% in participant who received PEP with HCQ as compared to the control group and there was no serious adverse event. But there is still conflicting scientific data to prove or disprove the efficacy of HCQ for the treatment and prophylaxis for SARS-CoV-2 infection. Being a tertiary care center PGIMER is catering many states which include Punjab, hariyana, himachal Pradesh, Uttara khand, Uttar Pradesh. This put the institute to handle highest burden of suspected cases of SARS-CoV-2 in northern India. So, this double blind clinical trial has been planned to evaluate the efficacy of HCQ as PEP for the prevention of COVID-19 in asymptomatic individuals who are at risk for SARS-CoV-2 infection. The asymptomatic individual with direct contact with laboratory confirmed COVID-19 cases will be randomized into one PEP group and one control/placebo group as per inclusion and exclusion criteria. Individual who will not give consent for HCQ prophylaxis and those with contraindication for HCQ therapy like, hypersensitivity to HCQ or 4-aminoquinolone derivatives, patients with known retionopathy, cardiac arrhythmia, G6PD deficiency, psoriasis and pregnancy will be excluded from the study. All symptomatic individual and all health care workers related to suspected or proven COVID-19 and who received CoVID-19 vaccine will be excluded from the study. The PEP group will receive tablet HCQ 400 mg q 12 hourly on day one followed by 400 mg once weekly for 3 weeks (total cumulative dose of 2000 mg). The control group will receive placebo instead of HCQ. Both the groups will receive standard care of therapy in the form of home quarantine for 2 weeks along with social distancing and personal hygiene. The participants will be followed up for 4 weeks telephonically or physically as and when required and will be enquired regarding development of any COVID-19 symptoms like fever, cough, sore throat, shortness of breath, diarrhoea, myalgia. During follow up nasopharyngeal swab of the participants will be taken for processing reverse transcription polymerase chain reaction (RTPCR) for the detection of SARS-CoV-2 RNA to confirm the CoVID-19. Samples for RTPCR will be taken when any asymptomatic participants becomes symptomatic and by the 5-14 days of contact in asymptomatic participants through in-hospital visit at the institute's COVID-19 screening clinic.

Safety and Immunogenicity Study of 2019-nCoV Vaccine (mRNA-1273) for Prophylaxis of SARS-CoV-2 Infection (COVID-19)

This is a phase I, open-label, dose-ranging clinical trial in males and non-pregnant females, starting at 18 years of age, inclusive, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety, reactogenicity and immunogenicity of mRNA-1273 manufactured by ModernaTX, Inc. mRNA-1273 is a novel lipid nanoparticle (LNP)-encapsulated mRNA-based vaccine that encodes for a full-length, prefusion stabilized spike (S) protein of SARS-CoV-2. Enrollment will occur at up to 3 domestic clinical research sites. Up to one hundred and fifty-five subjects will be enrolled into one of thirteen cohorts (10 micrograms [mcg], 25 mcg, 50 mcg, 100 mcg, and 250 mcg). Subjects will receive an intramuscular (IM) injection (0.5 milliliters [mL]) of mRNA-1273 on Days 1 and 29 in the deltoid muscle and will be followed through 12 months post second vaccination (Day 394). Follow-up visits will occur 1, 2, and 4 weeks post each vaccination (Days 8, 15, 29, 36, 43, and 57), as well as 3, 6, and 12 months post second vaccination (Days 119, 209, and 394). The primary objective is to evaluate the safety and reactogenicity of a 2-dose vaccination schedule of mRNA-1273, given 28 days apart, across 5 dosages in healthy adults. Optional Substudy: This is an optional third mRNA-1273 vaccination substudy, in subjects 18 years of age and older, who received both the first and second mRNA-1273 vaccinations in the main study and meet all other substudy eligibility criteria. This optional third mRNA-1273 vaccination substudy is designed to assess safety, reactogenicity, and immunogenicity through 12 months post third vaccination (Day 731). Subjects who receive the third mRNA-1273 vaccination will exit the Schedule of Activities for the main study and will enter the Schedule of Activities for the optional substudy. Up to one hundred and twenty subject will be enrolled into two cohorts (consisting of participating subjects who received 2 doses of 25 or 50 mcg and participating subjects who received 2 doses of 100 and 250 mcg). Subjects will receive an IM injection (0.5 mL) at a dosage of 100 mcg/0.5 mL. The primary objective is to evaluate the safety and reactogenicity of a third mRNA-1273 vaccination, at a dosage of 100 mcg.

ACTIV-5 / Big Effect Trial (BET-B) for the Treatment of COVID-19

This is a platform trial to conduct a series of randomized, double-blind, placebo-controlled trials using common assessments and endpoints in hospitalized adults diagnosed with Coronavirus Disease 2019 (COVID-19). Big Effect Trial (BET) is a proof-of-concept study with the intent of identifying promising treatments to enter a more definitive study. The study will be conducted in up to 70 domestic sites and 5 international sites. The study will compare different investigational therapeutic agents to a common control arm and determine which have relatively large effects. In order to maintain the double blind, each intervention will have a matched placebo. However, the control arm will be shared between interventions and may include participants receiving the matched placebo for a different intervention. The goal is not to determine clear statistical significance for an intervention, but rather to determine which products have clinical data suggestive of efficacy and should be moved quickly into larger studies. Estimates produced from BET will provide an improved basis for designing the larger trial, in terms of sample size and endpoint selection. Products with little indication of efficacy will be dropped on the basis of interim evaluations. In addition, some interventions may be discontinued on the basis of interim futility or efficacy analyses. One or more interventions may be started at any time. The number of interventions enrolling are programmatic decisions and will be based on the number of sites and the pace of enrollment. At the time of enrollment, subjects will be randomized to receive any one of the active arms they are eligible for or placebo. Approximately 200 (100 treatment and 100 shared placebo) subjects will be assigned to each arm entering the platform and a given site will generally have no more than 3 interventions at once. The BET-B stage will evaluate the combination of remdesivir with lenzilumab vs remdesivir with a lenzilumab placebo. The primary objective is to evaluate the clinical efficacy of different investigational therapeutics relative to the control arm in adults hospitalized with COVID-19 according to clinical status (8-point ordinal scale) at Day 8.

Organizational Measures to Prevent and Control COVID-19 Infection in Nursing Homes on the Risk of Death of Residents

The COVID epidemic has shown very high mortality among older people, especially among polymorbid and dependent subjects. In addition to the classic risk factors of age, dependence and associated co-morbidities, community life exposes to specific increased risks in the event of this easily inter human transmissible viral epidemic. In France, according to the Drees data (Ehpa study, 2015) more than 600,000 elderly people currently live in nursing homes (NH). Since March 28, a national guidance for monitoring the COVID epidemic in NH has just been set up. In France, 14 178 of the 29 319 COVID deaths (48.35%) by June 10th 2020 occurred among NHs residents. Work to consolidate these data is underway, suggesting a much heavier balance sheet. Faced to this threat, in addition to practical recommendations (barrier protection gestures), strict instructions were also announced to all NH to keep their residents safe from COVID : restricting all visitors, all volunteers and nonessential personnel, and more recently, confining residents in their room in case of incident case of COVID in the NH. Organizational factors of NH such as the prevention strategies deployed before and during the epidemic (pneumococcal vaccination, restricting group activities), as well as NH internal resources (equipment, nursing staff) and health resources in the NH environment (hospital partnerships, support devices, telemedicine) lead to heterogeneous situations and could influence the death rates of residents. On the other hand, social isolation can also precipitate the decline of fragile residents. Beyond the immediate and directly risks linked to COVID-19, the present hypothesize that the organizational measures (guidance and recommendations) put in place can have, during and at a distance from the outbreak, beneficial effects but also deleterious effects depending on the severity of the outbreak of a geographic area. More precisely, the hypothesis is that strong and well-followed recommendations at the time of the epidemic were associated with a reduction in the risk of total death in particular of deaths related to COVID in the zones most affected by the epidemic but also that strong and well-followed recommendations were associated with an increased risk of total death, in particular of deaths unrelated to COVID in the areas least affected by the epidemic.
