Filter by:This proposal seeks to enhance uptake and completion of COVID-19 vaccination among African American and Latinx public housing residents in South Los Angeles. Given the multiple disparities experienced by public housing residents, the investigators will utilize a theoretically-based, multidisciplinary and culturally tailored intervention to provide education at multiple levels and implement innovate strategies to engage this population in the uptake of COVID-19 vaccination.
Background: Respiratory viruses circulate throughout the year and around the globe. Wearable and sensor devices, like smartwatches, may be able to help monitor infectious diseases. Researchers want to use them to learn how respiratory viruses affect people in different ways. Objective: To use digital devices to collect data from participants in challenge studies that could indicate subtle changes in health during an infection that might otherwise go unnoticed. Eligibility: Healthy adults who have enrolled in a challenge study. Design: Participants will stay at NIH for at least 9 days and then they will have outpatient visits. While at NIH, participants will wear a smartwatch at all times. It will record data like temperature, heart rate, breathing rate, and movements. Participants will have 2 smartphones. One will be recording at all times to listen for coughing. Participants will use the other smartphone to check their vital signs. They will collect data like heart rate, temperature, and the level of oxygen in the blood every 4 hours during the daytime. Participants will perform tasks every 4 hours during the daytime. They will record themselves coughing, breathing in deeply, and reading aloud. They will take pictures and videos of their face. A bedside sensor will record participants while they sleep. It will record heart rate and breathing rate. It will also look at sleep activity, such as movements participants make during sleep and how deeply they sleep. Participants sharing the same room will be exposed to the same challenge virus. For outpatient visits, participants will use one smartphone and the smartwatch to complete the above tasks. Participation will last from 10 weeks to 1 year.
The new coronavirus (SARS-CoV-2) causing COVID-19 is an RNA virus coated with a capsid and a peri-capsid crossed by glycoprotein structures. The external proteic structure, which attacks human cells, is a potential target to therapeutic interventions against virus replication in airways. Since high temperature can cause irreversible denaturation of proteins and loss of SARS CoV and SARS CoV-2 infectivity was obtained after heating at 56 ◦C for 15 and 30 min in liquid environments respectively, we designed a protocol aimed at damaging SARS-CoV-2 capsid through steam inhalation cycles. Although the ominous consequences of COVID 19 infections has directed medical attention toward solidly established medical approaches, the European Pharmacopoeia VI edition also quotes steam inhalations as a procedure to treat of respiratory diseases. Based on these suggestions we established a quasi-randomized clinical trial enrolling 200 asymptomatic or paucisymptomatic patients in whom rhino-pharyngeal-swab revealed a SARS-CoV-2 infection. The study protocol consisted of exposure of airway mucosae to humidified steam (pH 8 per NaHCO3 and hypertonic 15 g/L NaCl) through steam inhalation for at least 20 min (4 cycles of 5 min) daily, for 10 days. The objective of the study is to reduce the viral shedding using steam inhalations.
The COVID-19 pandemic has highlighted deleterious US health inequities. Specifically, African Americans, Latinos, and Native Americans have and continue to shoulder a greater burden of COVID-19 infections and deaths in the US. In addition to existing racial and ethnic disparities are rural health and regional disparities. Given the disproportionate impact of disease in US communities of color and also in rural and southern regions of the US, there is no doubt that these at-risk subgroups will continue to experience higher rates of coronavirus-related mortality as well as other long-term health outcomes as compared to other US populations. It is unknown how healthcare providers and other key at-risk subgroups within the US will receive COVID-19 vaccines. For success in immunizations, the US will need to reach their most at-risk and vulnerable populations. In addition to at-risk populations, a successful immunization strategy will involve engaging providers to support clear, consistent, and strong vaccine recommendation. It is critical to build vaccine trust, confidence, and overall acceptance of COVID-19 vaccines among healthcare providers and key at-risk subgroups, especially given the accelerated production timeline of these vaccines. Likewise, tailored vaccine messaging for key subgroups is vital in achieving vaccine confidence and trust. The proposed study will explore perceptions, confidence, trust, and uptake of potential COVID-19 vaccines among healthcare providers (nurses and doctors) and key at-risk population subgroups (minority populations living in the rural south) and will develop and test vaccine messaging that boosts vaccine confidence and trust among these key at-risk subgroups.
A series of microbiota were correlated inversely with the disease severity and virus load. Gut microbiota could play a role in modulating host immune response and potentially influence disease severity and outcomes.
The purpose of this study is to examine how patients with multiple myeloma (MM) have been impacted by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. The study will use a questionnaire to further understand how patients are being affected and gather information in order to track the long-term effects of the coronavirus. The scope of the questionnaire will include, COVID-19 diagnosis and treatment, changes in myeloma treatment and care, clinical trial familiarity, health and fitness, and quality of life. This questionnaire is a follow-on to the "MM and COVID-19" questionnaire.
Best Practices to Prevent COVID-19 Illness in Staff and People With Serious Mental Illness and Developmental Disabilities in Congregate Living Settings is a research study aimed at developing, implementing, and evaluating a package of interventions specifically designed to reduce COVID-19 and other infectious-disease incidence, hospitalizations, and mortality among staff and adults with Serious Mental Illness and Intellectual and Developmental Disabilities in congregate-living settings.
This is a single-blind, parallel-group, randomized pilot study designed to evaluate and compare the efficacy of 3 different mouthwashes containing 0.2% Chlorhexidine digluconate, 1.5% Hydroxide peroxide or Cetylpyridinium chloride in reducing Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load in the saliva of COVID-19 positive patients at different time-points. A convenient sample of up to 40 COVID-19 positive patients diagnosed via test and/or presenting COVID-19 clinical symptoms will be identified in the inpatients and/or outpatient clinics at the Newham University Hospital and at The Royal London Hospital, Barts Health National Health Service (NHS) Trust, United Kingdom (UK). The study will consist of one visit. Unstimulated saliva samples will be collected from all COVID-19 positive patients before and at 30 minutes, 1, 2, and 3 hours after mouth rinsing (Group 1-3 ) or no rinsing (Group 4). Viral load analysis of saliva samples in the different time-points will be then assessed by Reverse Transcription quantitative PCR (RT- qPCR).
Preoperative antiseptic mouth rinses have been widely used as a standard protocol before routine dental treatment reduces oral microorganism counts. During dental procedures, aerosolized microorganisms contaminate the dental environment and nearby surfaces and remain suspended for 4 hours. Thus, the reduction in the number of aerosolized microorganisms by pre-procedural rinsing may reduce cross-contamination between dentists, office personnel, and patients. Recent reviews have advocated the use of preoperative rinsing to control and reduce the risk of SARS-CoV-2 transmission. However, no clinical studies have been done yet to support the effectiveness of any pre-procedural oral rinses against SARS-CoV-2. The proposed study will mitigate the spread of COVID-19 disease in dental healthcare facilities and ensure the patients' good health and healthcare workers. The purpose of this clinical trial is to compare the efficacy of four commercially available mouth rinses povidone-iodine (PVP-I), hydrogen peroxide (H2O2), cetylpyridinium chloride (CPC), sodium hypochlorite (NaOCl) on the salivary SARS-CoV-2 viral load at four-time points (baseline and 5-, 30-, and 60-min post rinsing) relative to two control groups (distilled water and no-rinse) in a cohort of positive COVID-19 patients.
Rumors circulate widely during public health crises and have deleterious consequences. In this study, we seek to document the base rates of migrant workers' rumor exposure and identify predictors of rumor hearing, sharing and belief.
