Filter by:Screening for STIs in MSM is based on multisite samples: urine, anal and oral for PCR targeting C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis, whereas only vaginal self-sampling is recommended in women. Recent publications and observations suggest that a substantial number of STIs are under diagnosed with the current recommendations. The main objective of the study is to assess the number and percentage of additional C. trachomatis and N. gonorrhoeae infections diagnosed by a multiple sampling strategy in women, particularly when the vaginal sampling is negative The secondary objective will assess the acceptability of anal and oropharyngeal self-sampling relative to vaginal self-sampling in women.
The goal of this clinical trial is to assess the safety and immunogenicity of a self-replicating (sr) RNA-based vaccine, JCXH-105, in the prevention of Shingles (Herpes Zoster) Participant will be randomized to receive either JCXH-105 or Shingrix.
Carbapenem resistant Enterobacteriaceae (CRE) colonization of patients discharged from hospitals is a source of transmission to the community. In a cluster randomized controlled trial the effect of a bundle of interventions will be assessed on CRE transmission from CRE+ index patient discharged from hospital to HouseHold (HH) members. The districts in two provinces will be randomized to intervention or control. An information, communication, education and hygiene intervention, developed in collaboration with local health authorities, will aim to improve hygiene and decrease antibiotic (AB) use. The effect will be evaluated on CRE transmission between HH members, livestock and environment through consecutive CRE screening using fecal and hospital effluent samples cultured on carbapenem selective media. Knowledge, Attitudes, Practice surveys with smartphones will assess health seeking, AB use and hygiene adherence, hence detecting the effect of interventions. If transmission of CRE +/- Colistin Resistant Enterobacteriaceae (CoRE, common among livestocks) is detected the source will be investigated including livestock and food, targeted information will be given and evaluated. In hospitals the effect of cohort care will be assessed on CRE acquisition, hospital acquired infection, treatment outcome, costeffectiveness and contamination in sewage water. Mechanisms of resistance, relatedness of CRE isolates in different One Health departments, and rate of CRE transmission from humans to animals and vice versa, will be assessed through Whole Genome Sequencing (WGS).
This protocol describes the challenge non-typhoidal Salmonella (CHANTS) study. This is a first-in-human phase 1, double-blinded, randomised, dose-escalation human infection study, conducted in healthy volunteers aged 18 to 50 years. The primary objective of the study is to perform a dose escalation with two strains (ST19 or ST313) to determine the infectious dose required for 60-75% of volunteers to develop Salmonellosis using a composite diagnostic criterion. The secondary objectives of the study are to describe and compare the clinical and laboratory features following controlled human infection. It is hoped that the successful establishment of an NTS human challenge model can be used in the future to test candidate vaccines for NTS disease.
The purpose of this study is to evaluate the antiviral effect, safety, tolerability, and pharmacokinetics of STP0404 in treatment naïve adult participants living with Human Immunodeficiency Virus Type 1 (HIV-1) infection.
The goal of this clinical trial is to assess tolerability, safety and immunogenicity of the Flu-M Quadro vaccine as compared to the Ultrix® Quadri vaccine in volunteers aged between 18 and 60. Participants were given Flu-M Quadro [inactivated split influenza vaccine] with preservative or Flu-M Quadro [inactivated split influenza vaccine] without preservative or Ultrix® Quadri vaccine.The volunteers of each group were vaccinated with a single dose vaccine. Researchers assessed the tolerability, safety and immunogenicity of the Flu-M Quadro quadrivalent inactivated split influenza vaccine. Researchers performed a comparative assessment of the tolerability, safety, and immunogenicity of the Flu-M Quadro quadrivalent inactivated split influenza vaccine and the Ultrix® Quadri vaccine.
Studies on sonication suffer from a heterogeneity which makes their analysis complex, due to the absence of a gold standard allowing positive cases to be defined unequivocally. Thus, the sensitivity of the technique has been assessed on cases defined in different ways, which makes the studies difficult to compare (number of samples taken, number of positive samples, variable duration of culture, etc.). It should nevertheless be noted that the majority of the series conclude with a higher sensitivity than that of standard samples, in particular in the event of a strain with difficult growth (Cutibacterium acnes, deficient Streptococci) or in the event of prior antibiotic therapy. In the absence of a comparative reference allowing to conclude on the intrinsic performances of sonication as a diagnostic test, it seems interesting to evaluate its contribution in current practice, in particular in the difficult cases where the standard culture does not make it possible to fulfill the criterion. major (zero or only one positive sample). To the knowledge of the investigators, there is no study of this kind, which could make it possible to specify the place of this technique in the diagnostic procedure and to improve the care of patients.
Surgical site infection (SSI) is one of main complication in surgery. It usually occurs within 30 days post operation. The superficial SSI is an infection of skin and subcutaneous layer, clinically presented by pus oozing. Furthermore, seroma hematoma and wound dehiscence are also clinical signs of superficial SSI. Nowadays, there are studies which report methods reducing SSI by placing negative pressure drain within surgical wound. It can reduce serum in subcutaneous layer which is found in every surgical wound, especially in clean-contaminated and contaminated wound. Many studies show that placing negative pressure drainage within a surgical wound can reduce superficial SSI and decrease hospital length of stay by comparing with the control group. The objective in this study to compare the rate of SSI of clean-contaminated and contaminated surgical wounds between the patients whose wounds are placed with negative pressure drainage and patients who were not placed with negative pressure drainage.
A randomized controlled study was conducted to determine the effects of vaginal estrogen and human interferon alpha 2b vaginal effervescent capsules on vaginal microecology in perimenopausal and postmenopausal women. To determine whether there is a synergistic effect between the two in the treatment of HPV infection in perimenopausal and postmenopausal women. To observe the effects of two drugs alone and combined on the vaginal immune environment of patients.
The main objective of the study is to compare the effectiveness of moxifloxacin triple therapy with levofloxacin-based sequential therapy in terms of eradication rate, safety, and patient compliance.
