The female hormonal profile is of utmost importance for the assessment of the endocrinological functional status and the diagnosis of diseases. The analysis must delimit their normality intervals based on the manufacturer's cut-off points. Due to not all intervals can be evaluated before use, it is imperative to verify the reference intervals to achieve uniformity in the interpretation of results in the female population. We determine the reference intervals of five female sex hormones [Follicle Stimulating hormone (FSH), Estradiol, Luteinizing Hormone (LH), Prolactin, and progesterone] using electrochemiluminescence in the Cobas e411 (Roche). We included female patients >18 years old, between the 3rd and 15th day of the menstrual cycle (follicular phase) and had no previous medical history or recent medication. For reference intervals analysis, we followed the recommendations of the CLS...

Introducción: El miedo a la COVID-19 se distribuye por todo el mundo y afecta a todas las comunidades, incluidos los estudiantes universitarios. Es necesario tener herramientas para medir este miedo. Objetivo: Validar la traducción al español del cuestionario FCV-19S (Fear of COVID-19 Scale). Métodos: Estudio transversal basado en cuestionarios online, realizado en universitarios peruanos de pregrado, durante el primer brote de la COVID-19. Se incluyeron estudiantes con idioma español nativo, acceso a internet y se excluyeron sujetos con problemas de compresión del lenguaje. La traducción del cuestionario se realizó bajo un protocolo estandarizado y se aplicó una evaluación observacional para valorar la validez y confiabilidad de FCV-S19 con α de Cronbach, correlación de Pearson y análisis factorial. Resultados: Se encuestaron 208 estudiantes universitarios, con edad promedi...

Objective To ensure the health of newborns, it is necessary to perform high-quality diagnostic tests. The TORCH panel is a set of tests that identifies infectious pathogens such as Toxoplasma (Toxo) and Cytomegalovirus (CMV) that are common in low-setting populations. We performed TORCH panel quality planning using six sigma in a reference laboratory at Peru. Results This was a cross-sectional study. TORCH tests include Toxo, Rubella, CMV, and Herpes. We processed all samples by fourth-generation ELISA on the GEMINI XCR200 analyzer (Diatron, Budapest, Hungary). We obtained the imprecision from the annual data of the external quality assessment plan and we used the CLSI EP12-A3 guideline. In a total of 44,788 analyses, the average imprecision was 3.69 ± 1.47%, and CMV had lower imprecision (2.3 and 2.6% for IgM and IgG, respectively). Quality planning of the TORCH panel allowed estim...

Background: The effect of cannabis on cholesterol and lipid balance has been reported for decades. However, there are conflicting reports on the reduction of low-density lipoprotein (LDL-C) and total cholesterol. The purpose of this study was to determine the immediate changes of Cannabis spp. consumption by pyrolytic route in heavy users. Methods: A cross-sectional study on 20 Peruvian heavy cannabis users (mean age: 31 ± 9.5 years). The inclusion criteria were males with an average weight of 50–70 kg, normal BMI, and having used cannabis, without association with other drugs, for at least one year with a high frequency per week (use: 4–7 days/week). High-density lipoprotein (HDL-C), LDL-C, and total cholesterol were evaluated 30 and 120 min after the administration of Cannabis spp. (~0.2 g by inhalation). Results: Of the total 12 (60%), 10 (50%), and 11 (55%) had desirable total c...

Background:Euphorbia huachahana (Klotzch & Garcke) Boissier (Huachangana)(EhKGBh)has been used for over a century for medicinal purposes in the Peruvian population; however, itssafety and possible toxic effects of use have not been reported. The purpose of this study was todetermine the acute hepatic and renal toxicity of EhKGBh in Holtzman rats. Methods: Analyticaland experimental study. The population consisted of 52 rats of both sexes weighing between 300 and350 g divided into four groups: G1 and G2 EhKGBh groups (26 rats each) and two control groups(10 rats each). The experimental group was administered EhKGBh at a single dose of 2000 mg/kg P.O.to demonstrate toxicity during the 14-day follow-up. A daily assessment of alanine aminotransferase(ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total bilirubin (TBIL), andconjugated bilirubin (CBIL) was performed. Resul...

“Introduction: As face-to-face medical education was restricted during the pandemic; digital tools have been deployed to continue education showing a good educational impact in most countries. However, the perception of medical students in Peru on eLearning has not yet been investigated. This study assessed the perception of 440 medical students from two national universities in Peru on the characteristics and limitations of eLearning during 2021. Materials and methods: We conducted a cross-sectional study using the self-administered survey Encuesta Virtual en Tiempos de COVID-19 (EVI-CV19) on students between the second and sixth medical year of the Universidad Nacional Mayor de San Marcos (UNMSM) and the Universidad Nacional San Luis Gonzaga (UNSLG, n=325). Results: The majority of students were under 30 years of age (93.9% vs. 97.2%, p=0.084), and female (67% vs. 64%, p=0.107). Of t...
