Active clinical trials for "Urinary Tract Infections"

This study aims to evaluate the diagnostic and prognostic performance of a novel mRNA diagnostic/prognostic classifier (interprets the expression of 29 host response mRNA biomarkers) from whole blood in adult patients presenting to emergency departments (ED) with suspected infection.

The purpose of this trial is to make a comparison between the use of antiseptic silver alloy-coated silicone urinary catheters and the use of conventional silicone urinary catheters in spinal cord injured patients to prevent urinary infections.

Urinary tract infection (UTI) is relatively common in infants, with an occurence rate of up to 10%. Analysis of collected urine for the presence of bacteria or fungus is the only way to make a certain UTI diagnosis. Sterile collection of urine can be achieved in newborn infants by urinary catheterization (UC) where a catheter is passed through the urethra into the bladder, suprapubic aspiration (SPA) where a needle is inserted into the bladder through the abdominal wall, or 'clean catch' where urine is collected into a sterile bottle as the baby urinates during preparation for UC. The main advantage of SPA is that it bypasses the bacteria that normally resides in the urethral opening, thus minimizing the risk of contamination. Some studies have suggested that SPA is better than UC for collecting urine in a sterile fashion in the neonate due to the difficulty of doing sterile UC in small infants resulting in more contaminated samples (also called a false-positive urine culture); there is still no clear best choice. UC is commonly used in many Neonatal Intensive Care Units (NICU) as it is considered less invasive, can be done by the nursing staff, and generally has a higher chance of obtaining urine. SPA is a simple and safe alternative and, although it may be more painful than UC, it is performed more quickly. The reported success rate for SPA is variable, but is greatly increased when an ultrasound confirms urine in the bladder. The question remains: what is the best method for sterile collection of urine in neonates? In this study, the investigators will try to answer this question by collecting urine from neonates using either ultrasound guided SPA or UC and then comparing the contamination rates between these two methods. The investigators hypothesize that SPA will result in less contamination of urine samples. The investigators also hypothesize that there will be more success in obtaining an adequate urine sample (0.5 ml) by SPA, and that there will be no difference in associated complication rates between SPA and UC.

We hypothesize that probiotic Lactobacillus can augment antibiotic treatment of symptomatic urinary tract infection (UTI) in spinal cord injured patients, and also increase the time to the next episode of UTI.

Prospective study aiming at collecting clinical Escherichia coli isolates from patients with recurrent urinary tract infection; samples to be collected during routine procedures.

Urinary tract infection is a common infectious disease in clinic. Although urinary tract infection can be initially diagnosed by clinical sign and symptom, signs and urine routine, the application of appropriate antibiotic therapy depends on the further identification of pathogens. Metagenomic sequencing has been widely used in clinical pathogen diagnosis, especially in difficult infectious diseases. ICompared with tissue samples, cerebrospinal fluid, bronchoalveolar lavage fluid, whole blood and other samples, the application of mNGS in urine samples is relatively limited because incorrect sampling methods before and after collection of urine samples are easy to contaminate the samples and the colonization of distal urethra, periurethral skin and vagina will interfere with the interpretation of reports. Previous small sample studies have shown that the sensitivity of mNGS in urinary tract infection is high, but the specificity is relatively low, and there are many problems such as difficult interpretation of reports and low clinical conformity. This is closely related to the mNGS technology algorithm, such as the inability to eliminate the influence of urinary system background bacteria, and the ambiguity of short sequence alignment, which makes it difficult to distinguish homologous pathogens. In this study, based on the standard mNGS sequencing process, the improved Z value analysis method was used to select strictly enrolled clinical samples and compare them with pathogen culture to observe the clinical value of mNGS with Z value analysis method in the treatment of urinary tract infection.

The study will assess the risk of catheter associated urinary tract infection in women undergoing incontinence or reconstructive pelvic surgery. Women will be given an antibiotic or placebo at the time of catheter removal. The investigators hypothesize that prophylactic antibiotics will reduce the rate of infection.

Objectives The objective of this study is to help identify the best practice regarding the use of indwelling catheter after minimally invasive urogynecologic surgery. Investigators propose a randomized controlled trial comparing the immediate removal of indwelling urethral catheter, after minimally invasive sacrocolpopexy, to the present standard catheter removal on post operative day one. Evidence based catheter management will be helpful to both providers and patients in post-operative decision making. Specific Aims Aim 1: To demonstrate that immediate removal of catheter after minimally invasive sacrocolpopexy results in shorter hospital stay than removal on postoperative day 1. Aim 2: To demonstrate that immediate removal of catheter after minimally invasive sacrocolpopexy confers no increased risk of re-catheterization. Aim 3: To demonstrate that immediate removal of catheter after minimally invasive sacrocolpopexy decreases the occurrence of urinary tract infection. Design A randomized controlled trial comparing the standard overnight indwelling urethral catheterization with removal of catheter immediately post surgery after minimally invasive sacrocolpopexy, at Oregon Health & Science University. Outcome measures Primary outcome measures are hospital stay in hours after completion of surgery and need for re-catheterization. Hospital stay will be counted from the time the patient leaves the operating room to the time she leaves the hospital. To avoid confounding, investigators are only including the first / morning case of the day. For re-catheterization, investigators will evaluate if patient was able to void after completion of surgery. Investigators will compare the post voiding residuals, the need for re-catheterizations and the numbers of patients going home with an indwelling catheter between the two groups. Investigators will also compare the number of urinary tract infections, as documented by urine culture and subsequent treatment, between the two groups. Study Subjects Study subjects will be women undergoing minimally invasive sacrocolpopexy. Women will be invited to participate in the study during their preoperative visit. If they agree to participation, this will be noted in their chart. Randomization to group will occur immediately following surgery.

Nissle 1917 is an E. coli based probiotic used in the Europe for close to 100 years to treat gastrointestinal disorders and infections. The investigators will assess the safety and tolerability of this medication in Americans in a Phase 1 trial.
