We compared standard ST-segment analysis and ST/HR slope analysis of exercise ECG studies with reference to outcome of exercise thallium-201 studies in 341 patients. Sensitivity was significantly better using ST/HR slope compared with standard ST analysis. Specificity was not significantly different.

Objective: To evaluate the effect of disease stage, frequency and clustering of visual field (VF) tests, inclusion of 1 or both eyes, and 1 (1 arm; before and after a treatment) or 2 groups (2 arms; treatment and control arm) on sample size calculation in clinical trials.
Design: Clinical cohort study.
Participants: A series of VFs were simulated based on test-retest VF data in the early, moderate, and advanced stages of glaucoma with 231, 204, and 226 eyes, respectively.

Background: Infections may play a role in the etiology of sudden infant death syndrome (SIDS), with Bordetella pertussis being a potential agent. The objective was to analyze the association of SIDS and infant pertussis hospitalization rates over time, comparing a previously unvaccinated population (West Germany) versus a predominantly vaccinated population (East Germany).
Methods: We calculated SIDS rates per 1000 live births per state.

An accurate assessment of leachate levels necessitates the integration of various parameters. Traditional geophysical prospecting methods often lack measurable accuracy because they focus on individual parameters rather than effectively integrating data. This may lead to inconsistent estimates of leachate depth and make the evaluation of prediction reliability challenging.

Background: Alpine skiing requires flexibility, endurance, strength and rotational ability, which may be lost after long fusions to the pelvis for adult spinal deformity (ASD). ASD patients may worry about their ability to return to skiing (RTS) postoperatively. There is currently insufficient data for spine surgeons to adequately address questions about when, or if, their patients might RTS.

Study Design: A cross-sectional analysis of 10,000 cervical spine X-rays.
Objective: This study investigates the variations in C6S and C7S across demographic factors (gender, age, cervical curvature, symptoms) and explores their correlation. Additionally, machine learning models are applied to improve the accuracy of C7S prediction.
