Filter by:The Collaborative Open Research Initiative Study (CORIS) is a groundbreaking international research endeavor aimed at exploring vital topics within the field of health professions education. At its core, CORIS embodies the spirit of inclusivity by opening its doors to contributors from all corners of the globe, putting the power of research into the hands of the global community and fostering an environment of open collaboration and meaningful contribution. We invite anyone and everyone to join as collaborators and suggest questions for inclusion in the survey, ensuring that the research process is enriched by diverse perspectives. As a collaborator, you will not only have the opportunity to actively engage in survey design, question formulation, and the entire research process from start to finish, but also gain the prospect of achieving valuable publications, which may boost your professional career.
The present study is a randomized, double-blind, placebo-controlled, comparative study. 176 individuals will be screened, and considering a screening failure rate of 15 percent approximately 150 will be randomized in a ratio of 1:1 to receive either IP or placebo and will be assigned a unique randomization code. Each group will have at least 60 completed participants after accounting for a dropout/withdrawal rate of 20percent. The intervention duration for all the study participants is 7 days
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
The two main cytomegalovirus (CMV) prevention strategies are prophylaxis and preemptive therapy. Prophylaxis effectively prevents CMV infection after solid organ transplantation (SOT), but is associated with high rates of neutropenia and late onset of post-prophylactic disease. In contrast, preemptive therapy has the advantage of leading to lower rates of CMV disease and robust humoral and T-cell responses. It is widely used in hematopoietic cell transplant recipients, but is rarely used after solid organ transplant recipients due to logistical considerations.
Context Cytomegalovirus (CMV) infection is a frequent and potentially severe event in solid organ transplant (SOT) recipients. Most of available treatment display adverse effects that limit their use. Therefore, in case of an infection, it is of primary importance to identify the patients at high risk of severe infection and/or disease, and who ill benefit the most from antiviral therapy. As CMV infection is mainly controlled by cellular immunity, measuring specific anti-CMV T lymphocyte immunity could be an interesting tool for identifying these at-risk individuals. One of these tests is the QuantiFERON-CMV (QF-CMV) assay (QuiagenTM, Courtabœuf, France). Aim of the study The aim of the study is to determine the extent to which the QF-CMV can be use to identify, among SOT recipients with a CMV viremia, those that may not need antiviral therapy. Methods Participation to the study will be proposed to SOT recipients with an asymptomatic CMV infection with a blood viral load between 1,000 and 15,000 IU/mL. The QF-CMV will be performed in included participants, and the result will be given or not to the clinician in charge (according to the attributed group through randomisation). - In the group without result communication, the clinician in charge will determine whether a treatment is needed according to the guidelines and the local practices. - in the group with result communication, the clinician in charge will be advised not to introduce antiviral therapy if the result is positive, and to determine whether a treatment is needed according to the guidelines and the local practices if the result is positive. In the following weeks, the viral load will be monitored, along with creatininemia, cell blood count, and kalemia (to detect antiviral adverse effect). The participants will be sampled: - 5 to 12 days after QF-CMV sampling (V2) ; - 7 to 14 days days after V2 (V3 - between D12 and D26) ; - 7 to 14 days days after V3 (V4 - between D19 and D40) . Endpoints The primary endpoint is the rate of uncontrolled infection 5 to 12 days after QF-CMV sampling, defined as follows: - Blood CMV viral load >10,000 IU/mL [4 log]; - And/or increase in blood viral load ≥0.5 log IU/mL with CV otherwise >5000 IU/mL; - And/or the onset of CMV disease. The secondary endpoint is the is the occurrence antiviral adverse effects (hematoxicity or nephrotoxicity).
The purpose of this study is to evaluate the efficacy and the tolerance of letermovir as part of dual antiviral therapy (in association with valganciclovir) in renal transplant recipients with CMV DNAemia, requiring valganciclovir treatment per investigator's judgment.
Respiratory tract infections are among the leading causes of death worldwide and many of these infections are preventable through vaccination. One of the most important bacteria from an etiological and mortality point of view regarding respiratory and systemic infections is the gram-positive Streptococcus pneumoniae. Four types of vaccines are currently available for this pathogen: three pneumococcal conjugate vaccines (PCV13, PCV15, and PCV20) and one polysaccharide vaccine (PPSV23). In Italy, people over 65 years of age and people suffering from chronic pathologies with effects on the immune system would be advised to be vaccinated with the pneumococcal conjugate vaccine and with the polysaccharide vaccine as a second dose. However, there are no data available in Italy on vaccination coverage in these population categories and above all the vaccination rates in patients who have a history of an episode of invasive pneumococcal infection are not known. The aim of the study is to measure how many patients are vaccinated for S. pneumoniae after hospitalization for a systemic pneumococcal infection in order to understand patients' awareness of preventing this infection after receiving a first diagnosis.
This is a stepped-wedge, cluster-randomized, two-arm, open-label, clinical trial of an electronic clinical decision support tool (eCDST) for the diagnosis and treatment of lower respiratory tract infection (LRTI) among patients at three sites in Southern Province, Sri Lanka. The primary objective of this trial is to determine the impact of an electronic clinical decision support tool (eCDST) on clinical outcomes and antibacterial prescription in subjects with LRTI in the intervention group compared to the control group. The study will enroll 765 patients ≥ 14 years of age. Medical wards will be randomized in clusters to the intervention at intervals of 3-6 months until all clusters cross over. Participants will be followed for 30 days from enrollment to record clinical outcomes and any antimicrobials prescribed.
Given that WLWH are more likely to develop persistent HPV infection and CC, effective screening and the management and treatment of pre-cancerous cervical abnormalities is critical to decrease the global burden of cervical cancer. The vast majority of WLWH live in SSA, where resources are more constrained. Therefore, simple, affordable, and effective tools are needed for the prevention of cervical cancer in SSA. In this setting, the best method for treatment of screen-positive WLWH has not been determined. The proposed study will compare the effectiveness of TA vs. LEEP, for treating precursor lesions (CIN 2/3) and HPV infection in WLWH, identify the determinants of treatment failure, and develop a strategy to predict patients in whom treatment is likely to fail so that alternative treatments can be provided. Moreover, local evidence of the optimal method of treatments is necessary to inform health policy and promote adherence.
Retrospective analysis of clinical data from 50 hospital-admitted patients with suspected pulmonary infection (as judged by clinical manifestations and imaging findings) was performed on study participants who had collected two different samples of alveolar lavage fluid (BALF) and sputum and underwent metagenomic next generation sequencing (mNGS) and routine pathogen detection, respectively. The positive rate of pathogen detection and the consistency of pathogen detection results of the two detection methods were compared to evaluate the clinical manifestation and role of mNGS in pathogen diagnosis.
