Filter by:There is great variability in susceptibility from one person to another, and less than one in a hundred sexual exposures to HIV results in infection. In addition, some recent trial of methods to prevent HIV - including vaccines and microbicides - have actually increased HIV acquisition among trial participants for reasons that we do not fully understand. While we know that immune differences in the genital lining are an important determinant of whether a person is infected after a sexual HIV exposure, we don't know enough about these differences to be able to accurately assess a person's individual HIV risk. Therefore, the development of safe and non-invasive laboratory tests to estimate a person's susceptibility in the genital tract would be useful in clinical studies of new HIV prevention tools.
This study evaluates the link between genetic polymorphisms as r7903146, rs12255372 of TCF7L2 gene and the risk of developing hyperglycemia during Intensive care unit stay
Fitness athletes emphasize the value of staying lean, muscular and defined, and motivates and inspires followers through social media. We want to study the effect of such lifestyle on selected aspects of psychological and physical health in female fitness athletes, and compare the outcomes to a healthy, physically active female population.
The purpose of this study is to compare two methods for remote genetic counseling (telephone and two-way videoconferencing) for patients who are receiving disclosure of their APOE (apolipoprotein E) genotype. The target population will consist of males and females in the age range of 60-75 years who, as potential participants in a study (Generation Study), will need to receive genetic counseling and disclosure of APOE genotype. Subjects must be willing to receive genetic counseling and disclosure remotely. Subjects must be willing to be randomized to either telephone arm or videoconference arm.
The antimalarial drugs efficacy and safety study will be conducted in the Clinics and hospital of the Cameroon Development Corporation (CDC) Estates, Tiko Health District, located in a typical forest and rainfall area in the South West Region Cameroon. In this study, 350 children aged 6 months to 5 years who are found to have uncomplicated symptomatic malaria will be enrolled between October 2012 and March 2013. Participants will be randomized to receive one of the following medications. (i) DHA+PQ : dihydroartemisinin, 2.5 mg per kg, plus piperaquine phosphate, 20mg per kg daily for 3 days; (ii) ART LUM : Artemether, 2mg per kg, plus lumefantrine 10mg, twice daily for 3 days; (iii) AS+MQ: artesunate, 4 mg/kg/day, with mefloquine, 8 mg/kg/day orally once a day for 3 days. All study medications will be administered orally The Primary objective of this study are to compare the efficacy, safety and tolerability of orally administered artemether plus lumefantrine (ART+LUM), artesunate plus mefloquine (AS+MQ) and dihydroartemisinin plus piperaquine (DHA+PQ) combinations in the treatment of uncomplicated falciparum malaria in Cameroon in order to provide evidence that can be used to determining the optimum antimalaria treatment policy in Cameroon. The secondary objectives are as follows (i) To valuate the efficacy and safety of artemether plus lumefantrine (ART + LUM) and artesunate plus mefloquine (AS + MQ) versus dihydroartemisinin plus piperaquine (DHA + PQ) combination (ii) To compare the clearance of asexual parasites and gametocytes in each treatment arm (iii) To assess the clearance of fever (iv) Assess effect of each treatment arm on anemia This study is a randomized, double blinded clinical trial. After enrollment, participant will be randomized to one of the three treatment regimen. The treatment outcome will be assessed through a 42-day efficacy study. Participants who will exhibit early or late treatment failure and those with adequate clinical response and parasitological failure on day 14, 28 or 42 will be treated with quinine (25mg base per kg body weight per day in three divided doses for five days). In addition to antimalarial drugs oral paracetamol (50mg/kg body weight per day in three divided doses) will be administered for fever exceeding 37.5%. Polymerase Chain Reaction (PCR) -corrected 28 day and 42 day efficacy will be evaluated for each treatment episode.
This study is a multi-center, single-arm, open-label clinical study to assess the efficacy of one dose of ciprofloxacin given orally in subjects infected with untreated gyrase A (gyrA) serine 91 genotype Neisseria gonorrhoeae (N. gonorrhoeae) as determined by a real-time Polymerase Chain Reaction (PCR) assay. The study will enroll approximately 381 subjects to obtain an eligibility target of 257 subjects, per protocol, age 18 and older regardless of gender identification who are seeking care in Sexually Transmitted Disease (STD) clinics of up to eight of the participating sites in the United States. Subjects who have untreated gyrA serine 91 genotype N. gonorrhoeae of the rectum, or male or female urogenital tract identified by a positive culture or Nucleic Acid Amplification Test (NAAT) conducted at a prior visit will be offered enrollment in the study. They will receive one dose of directly observed ciprofloxacin 500 milligrams. Subjects not consenting to participate in the study will receive treatment per local standard of care. The duration of the study for each subject will be approximately 11 through 14 days. The primary objective of this study is to determine the efficacy of ciprofloxacin for treatment of uncomplicated N. gonorrhoeae infections with gyrA serine 91 genotype.
Patients with inflammatory back pain were shown to differ from healthy controls in genotype of the Angiotensin-converting enzyme (ACE), which regulates vasoconstriction/-dilatation. The aim of this study is to investigate whether genetic reduction of muscle perfusion might be a pathophysiological pathway of how genes influence chronic non-specific low back pain (LBP).
The aim of this study is to assess the impact of Schistosoma mansoni infection and its treatment on genital immunology and HIV susceptibility in Ugandan women.
The purpose of this study is to evaluate the benefit and tolerability of IQP-AS-119 for reduction of susceptibility to infections and other complaints after extreme physical stress (participation in a marathon).
This is a prospective case-control physiopathological study, which main objective is to determine the genetic host factors predisposing to candidemia. Secondary objectives are to develop new diagnosis tools using the biological collection, to describe and update epidemiology, to analyse the influence of genetic polymorphisms on prognosis.
