The abnormal biological activity of cytokines and their imbalance are implicated in developing rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Cytokine levels were measured in RA and SLE patients and compared to healthy controls using the Wilcoxon rank sum test and Kruskal–Wallis test. The relationship between cytokine levels and...
Abstract
Vitamin B12 (B12) is a molecule involved in several biological. Abnormally high levels are frequently found, but their causes can be multiple, and consequences have not been clearly elucidated. The objective of this review was to summarize the current evidence on the associations of elevated B12 and the development of cancer, and all-cause...

BACKGROUND
Neck circumference (NC) is a useful anthropometric measure for predicting obstructive sleep apnea (OSA). Ethnicity and sex also influence obesity phenotypes. NC cut-offs for defining OSA have not been established for the Latin American population.
OBJECTIVES

Introducción:
Evaluar la calidad de vida de los pacientes anticoagulados es importante; no existe en la actualidad una validación al español de la escala de satisfacción de anticoagulación de Duke (DASS).
Objetivo:
Realizar una validación lingüística y una estimación preliminar de las propiedades psicométricas en español colombiano de la escala de...
Objectives: Polysomnogram is the gold standard for the diagnosis of sleep-disordered breathing (SDB); a sensitive and specific alternative strategy would be ideal, due to its low availability, and screening patients at high risk of OSA is very important. This study aimed to determine the operating characteristics of screening tests in patients with...
Introducción: Se ha reportado una asociación entre los niveles altos de vitamina B12 y la ocurrencia de múltiples enfermedades. Objetivo: describir las características clínicas de pacientes hospitalizados con hipervitaminemia B12, así como la tasa de mortalidad a un año. Materiales y métodos: estudio observacional retrospectivo realizado en 93 paci...
La hemofilia A adquirida es una entidad poco reportada y potencialmente fatal, que se asocia con la aparición de autoanticuerpos contra el factor VIII de la coagulación. Si bien puede estar subestimada, se calcula una incidencia aproximada de 1 a 1.5 casos por millón de habitantes con una mortalidad reportada entre el 9 y el 33%. Se manifiesta con...
Los paragangliomas son tumores neuroendocrinos raros derivados de las porciones simpáticas y parasimpáticas de los paraganglios, la presencia de metástasis es la que determina la malignidad.
