Active clinical trials for "Infections"

This proposed pharmacokinetic study will test the hypothesis that in critically ill patients with respiratory failure requiring mechanical ventilation such as might be anticipated to be needed to treat patients with severe influenza pneumonia, oseltamivir administered enterally via nasogastric tube, with and without concomitant food or alimentation, will have similar oral bioavailability to that observed in ambulatory adults ill with influenza in whom oseltamivir therapy 75 mg BID is efficacious and well tolerated. Additionally, this experiment will test the hypothesis that increasing the dose (150 mg), with and without concomitant enteral feeding, will show a proportionate increase in bioavailability. Relative oral bioavailability will be assessed from plasma concentration vs. time over 12 hrs and urinary recovery of drug from 0 to 48 hrs after administration.

Patients undergoing Cesarean delivery (C-Section) with a body mass index of 30 or less will be given either 2 grams or 4 grams of an antibiotic before surgery. The antibiotic is intended to prevent infection from the surgery. It is unknown what the best dose for the usual medicine used for this purpose (an antibiotic medicine called cefazolin). Samples of the tissue just under the skin will be biopsied at the time the incision is made and at the time the cut is stitched or stapled closed. A sample of the muscle of the womb will be taken as the womb is stitched closed after the delivery. Blood tests will be done at the start and end of surgery to test the antibiotic level. A blood sample will be taken from the umbilical cord after the baby has been delivered and the umbilical cord has been cut. The umbilical cord blood sample will be tested for the antibiotic level. These tests will be used to find out if the usual dose of medicine is enough or if more medicine is needed to prevent infection in normal weight women undergoing c-sections.

Currently, the world is facing a SARS-CoV2 coronavirus epidemic, which is responsible for COVID-19. In France, this virus has already infected several million people and is responsible for the death of more than 127,000. Infection is associated with a higher number of cardiovascular events (myocardial infarction, stroke, cardiac arrhythmia, thrombosis ...) in the short and medium term after infection. The long-term complications of this infection are not yet known and are the subject of research in France and in the world. In order to investigate the possible long term sequelae of this virus infection, this research aims to evaluate the potential cholesterol abnormalities caused by COVID-19, which could play a significant role in the increase of cardiovascular risk in affected patients. A total of 180 analysable participants will be recruited in this study. They will be divided into four groups of participants that will be compared to one another: 30 participants who were infected with SARS-CoV2 with no or few signs and did not require hospitalization. 30 participants who were infected with SARS-CoV2 and whose severity of illness required hospitalization in a COVID unit 30 participants who were infected with SARS-CoV2 and required intensive care hospitalization due to severity of illness. 90 participants who were not infected with SARS-CoV2. For each participant, the study will last approximately 1 hour, the time to fill out the consent forms, to answer a few questions about their current medical history and finally to take a blood sample for lipid measurements.

This study is set up by an international core group consisting of infectious disease specialists, geriatricians, urologists, microbiologists, emergency physicians and primary care physicians to develop a consensus-based research definition of urinary tract infections. The absence of such a reference standard leads to misclassification bias and heterogeneity between studies making progress in the field of UTI difficult, for example with much needed near patient diagnostic tests.

Prosthetic joint infection (PJI) represents one of the most common reasons for failure among hip and knee prostheses, with an incidence of around 1-2%. Infection can occur early (within days of surgery) or late (over a year after surgery), and no specific early markers for infection onset exist. Given the significant costs to the NHS for corrective revision surgery, the added suffering and risk to patients from surgery, and the risk of enhancing antimicrobial resistance through the use of broad-spectrum antibiotics, a more specific predictive test for early onset of infection is required.

This study evaluates the possible correlation of early postoperative pain in a broad surgical adult population and infectious complications in de first 30 days after surgery. It is a large retrospective cohort study in a single center.

COVID-19 infection are characterized by fever and signs of acute respiratory infection. A worsening of respiratory symptoms that can lead to respiratory failure. The decompensation can then be brutal and require rapid recourse to respiratory assistance. The contribution of clinical examination (auscultation and monitoring of oxygen saturation in particular) remains unsatisfactory in predicting an unfavorable course. The interest of pulmonary ultrasound is known in the management of pulmonary infections. However, estimating the severity of lung damage at an early stage could be of great help in monitoring and caring for patients. Ultrasound could meet this need in general practice, the chest scanner is often unavailable in these situations. Ultrasound signs are associated with severe forms. The contribution of pulmonary ultrasound seems particularly interesting in the context of the reassessment of patients during the worsening phase of symptoms (D5-D10). Estimate the prevalence of ultrasound signs in patients with an acute respiratory infection suspected or confirmed to be COVID-19, at the time of the worsening phase (between D5 and D10 of the onset of symptoms). The prevalence of ultrasound lung lesions under COVID-19 may be essential to consider the development of the ultrasound tool in primary care. Indeed, if the contribution of ultrasound is now recognized in intensive care or emergency, its place in general medicine still raises questions.

The deployment of vaccination against SARS-CoV-2 from 2021 led to a modification in June 2021of previous recommendations concerning the postponing scheduled surgery suggesting local adaptations of this delay if epidemic developments appear. Today, the evolutions of the pandemic make these recommendations obsolete and impose the updating of the data produced during the first epidemic wave of 2020. Among these evolutions, the two most important are the existence of a large vaccination coverage on the one hand and the emergence of variants of lesser severity on the other hand

Vascular Prothesis Infection is a rare but an extremely serious complication. Diagnosis is often difficult (germs are found only in 50% of cases). Conventional imagery is often non-specific and difficult to interpret especially in early postoperative phase. Leukocytes isolated from the patient's blood are labeled with a radiopharmaceutical technetium 99mTc-HMPAO. The aim of this study is to assess the overall diagnostic performance of scintigraphy (hybrid SPEC-CT) with labeled leucocytes in diagnosis of subdiaphragmatic vascular prothesis infection.

The purpose of this study was about survey of prevalence of fungal infections among drug users referring to methadone wards of Hospitals in northeast region of Iran
