Objective: To evaluate the relationship between anthropometric profile and serve speed in male Peruvian tennis players. Methods: A quantitative, observational, cross-sectional, and analytical study was conducted with 79 male tennis players from the FiXU sports medical center in Lima, Peru, during 2023 and 2024. Variables such as height, weight, BMI, and limb dimensions were measured. Serve speed was assessed using a calibrated speed gun. Results: The average serve speed was 94.38 km/h (±9.98). The average height of the players was 174.61 cm (±4.17) and the average weight was 72.20 kg (±6.97). Height (r=0.796) and weight (r=0.533) showed significant correlations with serve speed. Weekly playing hours (r=0.611) and years of experience (r=0.435) also showed positive associations. Linear regression identified height (B=1.91, p<0.001), weight (B=0.76, p<0.001), and forearm length (B=...

OBJECTIVE: To determine the factors associated with anxiety in medical interns at a private university in the context of the covid-19 pandemic. METHODS: The study design is quantitative, observational, analytical, retrospective, cross-sectional. The sample was comprised of 343 human medicine interns, who were selected by a non-probabilistic snowball type sampling. The Coronavirus Anxiety Scale instrument was used for the diagnosis of anxiety. A Poisson regression model with robust bivariate and multiple variances was used to calculate the prevalence ratio and their respective 95% confidence intervals. RESULTS: The prevalence of anxiety and severe depressive symptoms of 22.74% and 6.71% respectively was found. Depressive symptoms RPa 3.274 (95% CI 1.06 - 10.09), having children RPa 2.61 (95% CI 1.26 - 5.38), and the diagnosis of COVID-19 in the last 12 months RPa 2.20 (95% CI 1.25 - 3.87)...

Introduction: Appendicular plastron is considered a progressive form of acute appendicitis, with a national prevalence of 2-10%. Currently management is often controversial. It is that from this context, it seeks to promote studies that can elucidate the variables associated with the management of this condition. Objective: to determine the epidemiological-clinical characteristics associated with the results of the management of the appendiceal plastron in adult patients in a reference hospital in Peru. Methods: Non-experimental study, with a quantitative approach, observational, analytical and cross-sectional design, whose sample consisted of 100 patients with a diagnosis of appendicular plastron. The data collection sheet was applied as an instrument. Likewise, a Poisson regression model was used to respond to the objectives. Results: The multivariate analysis showed that alcohol c...

Objectives: Validate a questionnaire to establish the perception of difficulties in the development of research projects in the students of the research area of ​​the Faculty of Human Medicine of the Peruvian University Los Andes. Methods: Validation study of a questionnaire designed and based on a Likert scale applied to the students of the subjects of Research process, Thesis seminar I and Thesis seminar II with stratified random probability sampling, content validity analysis and construct by expert judgment and statistical analysis of reliability with Cronbach's alpha. Results: The sample consisted of 85 students who agreed to be part of the study, of which 64,70% belonged to the female gender with an average age of 23 ± 5 years, subject of thesis seminar I 36,47%, Process research 34,12%, thesis seminar II 29,41%; 64,71% expressed difficulties in preparing the research project ...
