Introducción: La colecistectomía laparoscópica es una intervención que se realiza con frecuencia. Sin embargo, puede existir complicaciones perioperatorias convirtiéndola en una colecistectomía laparoscópica difícil. Existen diversos instrumentos predictores de una colecistectomía laparoscópica difícil, por ejemplo, el score de SPRECLAD. Objetivo: Identificar cuáles fueron los factores asociados a una colecistectomía laparoscópica difícil y evaluar la exactitud diagnóstica del score SPRECLAD para predecir dicha intervención en pacientes atendidos en el Hospital Militar central desde 2017 hasta 2020 Materiales y métodos: Estudio observacional, analítico, de cohorte histórica y evaluación de test diagnóstico. Se contó con una muestra de 141 pacientes atendidos en el Hospital Militar Central desde 2017 hasta 2020. El análisis de los datos recogidos de historias clín...

ABSTRACT Introduction: Vascular calcifications are part of the systemic disorders of bone mineral metabolism in chronic kidney disease (CKD) and represent one of the main causes of mortality.  Objective: To determine the clinical characteristics, prevalence of vascular calcifications and biochemical alterations of the bone mineral disorder in patients with CKD in hemodialysis therapy. Methods: Analytical, cross-sectional and non-experimental study. The prevalence of vascular calcifications (abdominal aorta) was determined according to the validated score (Kaupilla). The association of qualitative variables was used the Pearson Chi-Square. Results: The population included (n: 49), 65% of the patients were incidents in hemodialysis (> 6 months) with a mean hemodialysis time of 2.8 years. The not incident or new patients on hemodialysis (<6 months) was 35%. The average age was 62...
