Active clinical trials for "Bacterial Infections"

Optimal understanding of piperacillin-tazobactam pharmacokinetics in critically ill patients is lacking resulting in large variation of achieved exposure and possible inadequate therapy. The investigators hypothesize that drug dosing based on CKD-EPIcr-cys provides a useful method to individualize and optimize therapy for piperacillin-tazobactam and eventually improve outcome. In a multi-centre, observational, open-label study the investigators aim to define PK of free drug concentrations of both piperacillin and tazobactam in ICU patients and define a PK model for estimation of renal function that most accurately predicts piperacillin and tazobactam clearance.

The purpose of this work was to study the incidence, types, risk factors and causative organisms of bacterial infections in HCV Egyptian patients following Liver Transplantation. Moreover, to identify the emerging resistant strains and their proper antimicrobial therapy

A retrospective analysis was performed to determine the prevalence of multidrug- resistant organisms infection in ICU from October 2017 to October 2019. Non-MDRO patients were selected by random sampling in a ratio of 1:1 to the final MDRO group during the same period , and select the risk factors of infection with multi-drug resistant bacteria by comparing the two groups. Randomly select 30% of the sample size as the validation set, and the remaining 70% for the training set to establish a model. Using multi-factor Logistic regression, decision tree classification, artificial neural network, support vector machine, Bayesian network Method to establish risk assessment system for multidrug-resistant organisms infection respectively.Using validation set data to calculate the area under the ROC curve (AUC) and sensitivity, specificity of models and comparing the prediction accuracy of several models. Finally, choose a more suitable risk assessment system for multidrug-resistant organisms infection. Predict the patient's infection risk level according to the best risk assessment system and develop a low-to-high intervention plan.

Retrospective study of patients with a proved non-tuberculous osteoarticular infection (OAI) diagnosed in a rheumatology department during the years 2010-2020. The objectives are : To describe sites, type of micro-organism, clinical data, origin of infection, therapeutic modalities et outcome To compare OAI of urinary origin with those with another origin

Pleural Infection (PI) is a common, severe and complicated disease with considerable morbidity and mortality. (1,2) The knowledge of pleural infection microbiology remains incomplete. Sequencing of the bacterial 16S rRNA gene is a reliable methodology to discover the total microbiome of complex samples. The investigators designed a translational metagenomics study to study the bacteriology of pleural infection. The investigators will use pleural fluid specimens from a) the "Prospective validation of the RAPID clinical risk prediction score in adult patients with pleural infection: the PILOT study" (3) clinical trial and b) non-pleural infection patients. The pleural fluid specimens will be subjected to 16S rRNA next generation sequencing.

The purposes of this study are: To determine whether procalcitonin level at admission of pediatric patients with bacterial infections can be used as a marker for prediction of defervescence and hospitalization length To examine the kinetics of procalcitonin in pediatric patients with bacterial infections and persistent fever

To determine the value of increasing use of piperacillin/tazobactam as empiric therapy and restricting extended-spectrum cephalosporins in reducing the cases of ESBL producing Escherichia coli and Klebsiella pneumoniae in hematology and oncology units

o determine if extended-spectrum beta-lactamases, plasmid-mediated AmpC beta-lactamases, carbapenemases, chromosomal mutations in ribosomal RNA or other mechanisms of resistance account for antibiotic resistance in commonly encountered Gram negative and Gram positive bacteria at UPMC. Also to determine the molecular epidemiology and in vitro susceptibility of multiply resistant organisms at UPMC and to relate this to antibiotic use in the institution.

To determine the impact of the restriction of the third and forth generation cephalosporins on the reduction of intestinal colonization or infection with vancomycin-resistant enterococci (VRE) in a surgical intensive care unit (SICU)

Among 300 women that are scheduled a therapeutic abortion screening diagnopsis of BV are done using Gram stained vaginal smear and with a molecular test using PCR for 5 different bacteria.
