The Effect of Methenamine Hippurate to Reduce Antibiotic Prescribing in Elderly Women With Recurrent...
Recurrent Urinary Tract InfectionRecurrent urinary tract infection (UTI) in elderly women is a major driver of antibiotic prescription. Hence, the question of feasible and appropriate preventive measures are important issues in this field. Methenamine hippurate is frequently prescribed in Norway and Sweden as prophylaxis for recurrent UTI. Methenamine hippurate acts via the production of formaldehyde from hexamine, which in turn acts as a bacteriostatic agent, therefore methenamine hippurate is not defined as an antibiotic. According to a Cochrane review 2012 the rates of adverse events for preventing UTI was low. Although this review showed methenamine hippurate might be effective in preventing UTI in the short term, there is a need for large well-conducted randomised controlled trial (RCT) to clarify both the safety and effectivity of preventive methenamine hippurate for longer term use. This is particularly important for longer term use for people without neuropathic bladder disorders. A Norwegian longitudinal observational study including women aged 50-80 years with recurrent UTI indicated a significant and large reduction of more than 50% in antibiotic prescriptions for UTI after start of prophylactic methenamine hippurate. This further strengthens the need for an RCT of methenamine hippurate as prophylaxis for recurrent UTI.

Fluid Agitation Microbiologic Yield In Pleural Infection Feasibility Study
Pleural InfectionThe goal of this study is to compare the microbiologic diagnostic yield of pre-aspiration agitated pleural fluid versus that of conventionally aspirated fluid in pleural infection patients. The main question it aims to answer is, whether fluid agitation helps to increase the microbiological yield.

The COMBAT HBV Feasibility Trial
Hepatitis BVertical Transmission of Infectious DiseaseThis is a double-blind, randomized placebo-controlled trial (RCT) of a prophylaxis-for-all approach to prevention of mother-to-child transmission (PMTCT) of hepatitis B virus (HBV) in the Democratic Republic of Congo (DRC). HBV-infected pregnant women will be randomized to either receive tenofovir or placebo beginning at 28-32 weeks' gestation and continuing through 4 weeks' postpartum. Women will be followed every 4-6 weeks throughout the prenatal and postpartum period to evaluate for side effects related to the medication. Infants will receive a birth-dose of HBV vaccine, ideally within 24 hours. Participants will be followed longitudinally through 6 months' postpartum.

Carrageenan for the Prevention of Oral HPV Infection
Human Papilloma VirusThis is a placebo-controlled, triple-blind randomized clinical trial (RCT) designed to evaluate the feasibility of conducting a larger multicentric RCT investigating the effect of a Carrageenan mouthwash on oral HPV infection. Eligible participants will complete a single in-person visit at baseline, filling out a questionnaire on their electronic device and giving an oral rinse sample for HPV testing. They will receive an adequate supply of mouthwash and instructions on its use. They will subsequently be followed up for up to six months. Every two weeks, participants will fill out a follow-up questionnaire on mouthwash use and sexual activities and self-collect oral rinse sample to be returned by mail.

Local Antibiotics for Breast Implants
Implant ComplicationImplant Infection5 moreThe BREAST-AB Trial is a multi-center, randomized, double blind, placebo-controlled trial investigating the efficacy of local application of gentamicin, vancomycin and cefazolin in decreasing all-cause implant explantation after breast reconstruction.

High vs. Standard Dose Influenza Vaccine in Adult SOT Recipients
Immunization; InfectionTransplantation Infection2 moreThe influenza virus is a significant cause of morbidity in adult solid organ transplant (SOT) recipients. However, these individuals show a suboptimal response to vaccines including the standard-dose (SD) inactivated influenza vaccine (IIV). Recent studies have investigated two strategies to overcome poor immune responses in SOT recipients: (1) administration of high-dose (HD)-IIV compared to SD-IIV and (2) two doses of SD-IIV compared to one dose of SD-IIV in the same influenza season. The first study compared HD-IIV vs. SD-IIV in adult SOT and noted HD-IIV was safe and reported higher immunogenicity; however, the median post-transplant period was 38 months. In another phase II trial of adult SOT recipients, two doses of SD-IIV a month apart compared to one-dose SD-IIV revealed increased immunogenicity, with a median post-transplantation period of 18 months. Therefore, these studies lack evaluation in the early post-transplantation period in this vulnerable population when influenza disease is most severe. The administration of two-doses of HD-IIV in the same influenza season has also not been studied in SOT recipients. Moreover, the vast majority of SOT influenza vaccinations studies have not substantively evaluated prolonged immunogenicity. Thus, the optimal immunization strategy for SOT recipients less than 12 months post-transplant is poorly-defined. In addition, the immunologic predictors and correlates of influenza vaccine immunogenicity in SOT recipients have not been defined. The investigators hypothesize that adult solid organ transplant recipients that are 1-11 months out from transplant and are receiving high-dose inactivated influenza vaccine will have higher hemagglutination inhibition (HAI) geometric mean titers to influenza A antigens compared to adult SOT recipients receiving standard-dose inactivated influenza vaccine. To test this hypothesis and address the above critical knowledge gaps, The investigators propose to conduct a phase II multicenter randomized controlled trial comparing either two doses HD-IIV, two doses of SD-IIV, or one-dose of HD-IIV in adult kidney, heart, and liver SOT recipients 1-11 months post-transplantation. The results of this study will address significant gaps in knowledge regarding influenza vaccine strategies and immune responses in adult SOT recipients and will guide vaccine recommendations in this vulnerable population.

Protocol Design for Evaluating the Immunity of Bivalve Fluids From Anodonta Cygnea in SARS and COVID-19...
Coronavirus InfectionsCoronavirus Sars-Associated2 moreThe present work proposes to find if a bio-active composite in the hemolymph or plasma of the freshwater bivalve Anodonta cygnea is able to offer immunity and specificity for meliorating the major symptoms in human SARS and COVID-19 lineage infection. The Methodology concerns in silico procedures using organic fluids from 54 bivalves (in very specific conditions) to evaluate their therapeutic effects in 6 voluntary SARS and COVID-19 infected persons with an integrative diagnosis by a computational Mora®Nova apparatus to access the basal and experimental human physiological parameters.

Assessement of Viral Shedding Duration After a Respiratory Tract Infection in Oncology and Hematology...
Respiratory Tract Viral InfectionThe purpose of this study is to assess the duration of the viral shedding in hematology and oncology patients after a respiratory tract viral infection. This duration has not been much studied in that population whereas it is probably longer than that in immunocompetent patients. Thereby it may be a source of transmission amongst these immunocompromised patients.

Maternal- Fetal Infection
Neonatal InfectionThe purpose of the protocol is to validate a novel point of care multiplex system to detect and characterize microorganisms responsible for neonatal sepsis, as well as biomarkers of infection, from a simple vaginal sample, in order to improve the prevention of perinatal bacterial infections.
