Filter by:The purpose of this study is to provide data showing if there are any effects of GSK3036656 on a combined oral contraceptive containing Ethinyl Estradiol (EE) and Levonorgestrel (LNG), which will help inform future studies on suitable contraceptive measures to be used.
The goal of this observational study is to understand how tuberculosis (TB) infection impacts the function and development of the placenta, and whether TB infection can contribute to pregnancy-related disorders through effects on the placenta. The main questions it aims to answer are: - Does TB infection affect the structure of the placenta? - Does TB infection affect the function of the placenta? Pregnant women attending delivery clinics in Addis Abeba, Ethiopia, will be enrolled and classified for TB infection using a blood-based test. We will compare the following outcomes between women with TB infection and women without TB infection: - Pathological lesions of the placenta - Gene and protein expression patterns linked to pregnancy-related disorders - Infant outcome at birth and at 6 weeks after birth
Our study is a prospective observational non-randomized clinical trial where all the patients undergo the same procedure and every patient's own samples are compared to each other. We conduct EBUS TBNA and EBUS TBMCB to all the study participants and we are numbering the cryobiopsy samples to evaluate the number of biopsies needed to reach a definite diagnosis and to assess the added value of every sample taken from the same patient. Every patient's own samples are compared to each other and added value of EBUS TBMCB is defined as the difference in diagnostic yield between the EBUS TBNA alone and the combination of EBUS TBNA with EBUS TBMCB. Diagnostic yield is defined as the efficacy of the investigation module in reaching a definite diagnosis (percentage of cases with a definite diagnosis). Follow up four weeks after the procedure to assess the risk for postoperative complications.
The overall objective of this Aim is to design and iteratively adapt a home-based, mHealth- and oral testing facilitated strategy for implementing tuberculosis (TB) contact tracing in Cali, Colombia. Investigators will employ an iterative, community-engaged, participatory co-design process to optimize the feasibility, acceptability, usability, and appropriateness of the mobile health (mHealth) and oral testing strategy, in preparation for a future, appropriately powered implementation-effectiveness trial. This protocol includes the baseline contact tracing protocol and the procedures for determining adaptations to the mHealth strategy (i.e., nominal group technique).
The goal of this clinical trial is to test two advices on alcohol drinking in more than 10.000 Spanish adult drinkers (men of 50 or more years and women of 55 or more years). The main question it aims to answer is to test the non-inferiority advice of a moderate alcohol drinking pattern on all-cause mortality and other chronic disease like cardiovascular disease, cancer or type 2 diabetes. Participants will receive during 4 years an advice to drink alcohol following a Mediterranean Alcohol Drinking Pattern (MADP): consuming alcohol in moderation, avoidance of binge drinking and preference for red wine. Researchers will compare those who will receive a MADP advice with those who will receive an advice on abstention to see if the advice on MADP is not inferior than the abstention advice to prevent all-cause mortality and other chronic diseases.
Individual pharmacokinetic variability is an important driver of tuberculosis (TB) treatment failure particularly among undernourished populations, and that suboptimal serum drug concentrations are associated with delayed response to treatment, death, and acquired bacterial drug resistance. Serum drug exposures can be approximated by urine excretion as measured by spectrophotometry, replacing the need for specialized equipment for serum testing. Anti-TB pharmacokinetic variability has also been associated with enteric pathogen burden. The overall hypothesis is that urine spectrophotometry will identify people with below-target rifampin serum concentrations, which can be corrected to target levels after dose adjustment as confirmed by serum mass spectrometry. Therefore, this protocol includes a clinical trial to assess efficacy and safety of rifampin dose adjustment based on urinary excretion levels among adults and children who are being treated for drug-sensitive pulmonary TB at our longstanding collaborative research site in Haydom Lutheran Hospital, Tanzania.
This randomized trial uses the evidence-based Systems Analysis and Improvement Approach (SAIA) adapted for tuberculosis (SAIA-TB) to assess the comprehensive tuberculosis (TB) care cascade across 16 clinics in rural Eastern Cape, South Africa to improve patient outcomes. The aims of this study are to: - Evaluate the effectiveness of SAIA-TB use in clinics on TB cascade outcomes for TB patients and with high-risk contacts - Determine the drivers of SAIA-TB implementation success or failure across clinics The investigators hypothesize that SAIA-TB implementation will lead to a 20% increase in each of: TB screening, TB preventive treatment initiation, and TB disease treatment initiation during the 18-month intervention period.
Evaluation of the performance of an in vitro test, the STANDARDTM F TB LAM Ag FIA (SD BIOSENSOR, INC.) for the early diagnosis of tuberculosis (TB) infection. This test is for in vitro professional diagnostic use and intended as an aid to early diagnosis of tuberculosis infection. The test will be used according to the instructions for use (IFU).
This is a randomized, blind, positive-controlled study to explore the skin test dosage of recombinant mycobacterium tuberculosis fusion protein ( EEC) in the population aged 18 to 65 years old , and to further evaluate the safety and preliminary efficacy of EEC in the population aged 3 to 75 years old. In the first stage,180 healthy subjects, 140 tuberculosis（TB）subjects and 40 non-TB subjects with lung diseases aged 18 to 65 years old are divided into different groups through a randomized, blind methods. Every group carry out a low-dose (2.5μg/ml) or high-dose (5μg/ml) study, with 180 subjects in each dose group .Every subject injects intradermally EEC and EC randomly in both arms of the same person. Evaluate the consistency of assay results of EEC, EC and Interferon-Gamma Release Assay（IGRA）.Evaluate the sensitivity, specificity and consistency of assay results of EEC, EC and IGRA in healthy people, TB patients and non-TB patients with lung diseases, and determine the optimal dose of EEC for clinical auxiliary diagnosis of tuberculosis. In the second stage, 60 healthy subjects and TB subjects aged 3-17 years and 66-75 years old are divided into different groups through a randomized, open, single-arm method with the target dose. Evaluate the safety, tolerance and preliminary efficacy of target dose of EEC in healthy people and TB patients aged 3 to 17 years old and 66 to 75 years old.
According to the WHO report of 2021, approximately 10 million new cases were reported in 2020, of which 1 million occurred in the pediatric population. However, epidemiological data available on tuberculosis (TB) in pediatric age are extremely limited due to diagnostic challenges in this patient category. Furthermore, children are almost never included in national surveillance systems due to the lack of connections between individual pediatricians, pediatric hospitals, and national surveillance programs. It is therefore reasonable to assume that the disease may be significantly underestimated both in Italy and worldwide.
