Objective: High-quality data entry in clinical trial databases is crucial to the usefulness, validity, and replicability of research findings, as it influences evidence-based medical practice and future research. Our aim is to assess the quality of self-reported data in trial registries and present practical and systematic methods for identifying and evaluating data quality.

Study Design And Setting: We searched ClinicalTrials.

Growing demand for clinical research to improve evidence-based medicine in daily medical practice led to healthcare evaluation, which assesses the effectiveness of the existing care. The first step is identifying and prioritizing the most important evidence uncertainties. A health research agenda (HRA) can be valuable and helps determine funding and resource allocation, aiding researchers and policymakers to design successful research programs and implement the results in daily medical practice.

Purpose: Drug-coated balloons (DCBs) for femoropopliteal peripheral artery disease have been shown to be clinically superior and cost-effective compared to conventional percutaneous transluminal angioplasty (PTA). However, few studies enrolled patients with chronic limb-threatening ischemia (CLTI). Our objective was to study the cost-effectiveness of endovascular treatment with versus without DCB in CLTI patient populations in the Netherlands and Germany.

Nearly all bacteria are encased in peptidoglycan, an extracytoplasmic matrix of polysaccharide strands crosslinked through short peptide stems. In the Gram-negative model organism Escherichia coli, more than 40 synthases and autolysins coordinate the growth and division of the peptidoglycan sacculus in the periplasm. The precise contribution of many of these enzymes to peptidoglycan metabolism remains unclear due to significant apparent redundancy, particularly among the autolysins.

This study aims to discuss the role of open surgery in the treatment of renal lithiasis, including coralliform stones, with the advent of new less invasive techniques. We report a series of 53 cases of coralliform stones whose data were collected in our Hospital during a period of 7 years, from January 2011 to January 2018. The patients underwent open nephrolithotomy by lombotomy.
