Determina la prevalencia del desgaste energético-proteico en pacientes con enfermedad renal crónica terminal en hemodiálisis atendidos en el Hospital Nacional “Dos de Mayo” en el año 2021. Es un estudio observacional descriptivo transversal retrospectivo en pacientes con enfermedad renal crónica terminal en hemodiálisis atendidos en el Hospital Nacional “Dos de Mayo” en el año 2021. Para un nivel de confianza del 95%, una potencia del 80%, para una prevalencia esperada del 36%, se requerirá un total de 143 pacientes. Los datos serán recolectados a partir de un instrumento estandarizado en base a los objetivos del estudio. Se presentarán medidas de resúmenes para las variables cualitativas mediante frecuencias y porcentajes y medias y desviación estándar o mediana y rango en función al cumplimiento de los supuestos de normalidad. Los datos serán procesados en RStudi...

Critical reading from the point of view of evidence-based medicine is a structured reading that allows us to evaluate the validity and relevance of the results and the applicability of a clinical study in our patient. However, the level of critical reading in resident physicians is low, as various studies have described. In a study of oncology resident physicians, a poor level of critical reading of clinical research articles was found. And in the same way, deficient levels were found in cardiology and family medicine residents. In our country, this situation is unknown and it is most likely deficient. Reason why we prepared a small review to be able to share practical bases that help the resident of specialties apply in a simpler way the critical reading of clinical studies.

Introduction: Despite the fact that hematological alterations at the peripheral level are widely known, little is known about the alterations caused by COVID-19 at the bone marrow level. Objective: To determine the morphological alterations of the bone marrow caused by COVID-19. Material and methods: Systematic review and meta-analysis. Observational studies and reports and case series were included and editorials, reviews, letters to the editor were excluded. A search was performed in Pubmed, ScienceDirect and Scielo. The risk of bias was assessed using the NewCatell-Ottawa and Hassan Murad scales for case reports and series. The outcomes were the morphological parameters of the bone marrow. For the quantitative synthesis of the information, a proportion meta-analysis was performed using random effects in RStudio. Results: Hypercellularity occurred in 65% (95% CI: 51%-78%), maturation a...
