The authors describe the relative benefits of conducting meta-analyses with (a) individual participant data (IPD) gathered from the constituent studies and (b) aggregated data (AD), or the group-level statistics (in particular, effect sizes) that appear in reports of a study's results. Given that both IPD and AD are eq…

There is an increased momentum to improve nurses' expertise in dealing with end of life issues via a standardized education program, ELNEC. This program has not been evaluated systematically. This quasi-experimental, longitudinal study's goal was to measure ELNEC Program's impact on registered nurses' death anxiety, de…

The aims of this study were to conduct a systematic literature review on balneotherapy about the specific therapeutic role of mineral elements and other chemical compounds of mineral waters and derivate peloids/muds and to discuss the study methods used to evaluate it (in musculoskeletal conditions).

This study's objective was to familiarize the profession with determining skeletal maturation and skeletal age, and predicting growth potential by using cervical vertebrae images of lateral cephalograms. The investigation was done through repeated evaluations of 30 randomly selected, pretreatment lateral cepaholometric…

BACKGROUND: Our study investigated the susceptibility rate of ceftazidime-avibactam and the risk factors associated with its resistance by analyzing gram-negative bacteria isolated from various patient samples. METHODS: Between March and November 2020, 1119 gram-negative bacteria strains were isolated from patient sam…

BACKGROUND: The belief remains widespread that medical research studies must have statistical power of at least 80% in order to be scientifically sound, and peer reviewers often question whether power is high enough. DISCUSSION: This requirement and the methods for meeting it have severe flaws. Notably, the true natur…

PURPOSE: Obsessive-compulsive disorder (OCD) is a condition characterized by obsessions and/or compulsions.
