About 2 billion people worldwide are infected with tuberculosis (TB). Ninety percent of those people have latent TB infection (LTBI). Risk factors like malnutrition, diabetes mellitus (DM), and helminth infection can affect the development of active TB. Researchers want to study LTBI individuals with these issues to see how they may contribute to a person s higher risk for developing active TB. This study will take place in Chennai, India. Objective: To estimate the prevalence of malnutrition, DM, and helminth infections in people with LTBI. Eligibility: People age 14 65 with or without LTBI. Design: Participants will be screened with a medical history and physical exam focused on symptoms of active TB. Those who have TB symptoms will not take part in the study. Those who do not have TB symptoms will have a physical exam with vital signs, height, and weight. They will give blood and stool samples. Participants will be assigned to 1 of 6 groups. They will repeat some of the screening tests. They will give urine samples. Some groups will have a chest X-ray. Some groups will have an ultrasound of the abdomen. Participants will complete a survey about their history of smoking and drug and alcohol use. Participants will have data collected about their nutritional status and body composition. Their skinfold thickness, ratio of waist/hip circumference, and grip strength will be measured. Participants with DM, malnutrition, or helminth infection will be given standard of care or referred for follow-up treatment. Participation will last up to 6 months. ...
This study involves evaluating pediatric patients with central lines to determine differences in line complications and quality of life in those with a novel central line securement device (wrap) as compared to those who use a traditional securement device (dressing).
Plasma from patients who have recovered from coronavirus disease 2019 (COVID-19) is referred to as COVID-19 convalescent plasma (CCP), and may contain antibodies against SARS-CoV-2, the virus responsible for COVID-19. CCP infusion is being evaluated as a therapeutic or prophylactic approach in COVID-19 patients. The goal of this study is to help develop a bank of convalescent plasma in California, especially in medically underserved communities particularly affected by the disease. In parallel, CCP administered to COVID-19 patients will be collected and analyzed to determine whether the antibody profile correlates with clinical outcome. The purpose of this non-therapeutic study is to learn more about the CCP antibody profile and the effect it may have in treating COVID-19 infection.
In this trial patients will be treated with either a combination of therapies to treat COVID-19 or a placebo. Treatment will last 10 days, and patients will be followed for 6 months.
The purpose of this study is to evaluate how useful vitamin D supplementation is in reducing the severity of COVID-19 symptoms and the body's inflammatory and infection-fighting response to COVID-19. Individuals ≥50 years of age and older who are tested for COVID-19 and negative will be randomized (like flipping a coin) to either daily high dose vitamin D supplementation (6000 IU vitamin D3/day) vs. standard of care. Those individuals ≥50 years of age or older who test positive for COVID-19 at baseline will be randomized to bolus vitamin D (20,000 IU/day for 3 days) followed by high dose (6000 IU vitamin D/day) vs. standard of care for 12 months. All participants will receive a multivitamin containing vitamin D.
This is part of a feasibility study to compare the predicate standard FDA cleared test for serum to a point of care test Toxoplasma ICT IgG-IgM BK produced by LD Bio Diagnostic. The specificity and sensitivity in testing serum and whole blood will be compared. This study includes 70 persons either pregnant or non pregnant. This is being done in accordance with FDA requirements for clearance of a testing device . The investigators will use a standard FDA cleared test in all studies. The FDA has suggested that the investigators submit a pre subQ for a 510K and dual CLIA waiver. This allows the investigators also to determine feasibility of use of the predicate test in conjunction with the experimental test with volunteers, including men, women, and pregnant women.
In the past ten years, nucleic acid detection technology has overcome the limitations of serological detection, reduced missed detections due to window period, occult infection, etc., and its application in the field of pathogen detection has developed rapidly. Since 2015, domestic blood collection and supply institutions have fully popularized nucleic acid testing. The safety screening of blood sources mostly adopts the method of combining two times of enzyme-free negative and one time of nucleic acid testing, which excludes the guarantee of blood safety to the greatest extent. At present, the clinical pre-transfusion and pre-operative infectious disease screening in our country is still serological detection. The use of nucleic acid detection for infectious disease screening can better realize the significance of patients' pre-transfusion/pre-operative infectious disease screening. Therefore, this study will analyze the nucleic acid detection technology and clinical serological detection technology in order to solve three problems: - Explore the best detection strategy for patients with pre-transfusion/pre-operative infectious disease screening; ② Explore the confirmation process of the gray area results of infectious disease serological testing; ③ Better realize the significance of screening for patients' infectious diseases.
Safety, immunogenicity and efficacy of GSK S. aureus candidate vaccine (GSK3878858A) when administered to healthy adults (dose-escalation) and to adults 18 to 64 years of age with a recent S. aureus skin and soft tissue infection (SSTI). In the dose-escalation safety lead-in phase in healthy adults safety and immunogenicity of 4 different compositions is assessed. After safety has been shown in this phase, in the second phase, proof of principle (PoP) phase of the study in adults with a recent SSTI safety, immunogenicity and efficacy of the final composition of the vaccine is assessed.
This is a Phase 3, double-blinded, randomised placebo-controlled, multi-centred trial evaluating the efficacy of the four-component meningococcal B vaccine, 4CMenB (Bexsero®), in the prevention of Neisseria gonorrhoeae infection.The targeted population is 18-50 years-old men (cis and trans), trans women and non-binary people who have sex with men (hereafter referred to as Gay Bisexual Men+ [GBM+], either HIV-negative and taking pre-exposure prophylaxis [PrEP], or HIV-positive with undetectable viral load <200copies/ml and a cluster of differentiation 4 [CD4] count >350 cells/cmm) who have high N. gonorrhoeae incidence and are recommended by Australian guidelines to have regular, comprehensive sexual health screening. 730 participants will be enrolled and randomised 1:1 and stratified by clinical sites to receive two doses of 4CMenB vaccine or a matching placebo at 0 and 3 months by intramuscular injection. Recruitment is for 12 months and all participants will be follow-up 3-monthly for a period of 2 years. The trial aims to evaluate the efficacy of 4CMenB in the prevention of N. gonorrhoeae infection.
