Performance of the IS6110-TaqMan® assay in the diagnosis of extrapulmonary tuberculosis from different biological samples

Abstract INTRODUCTION: This study evaluated the performance of the IS6110-TaqMan® assay in different types of biological samples and tissues for laboratory diagnosis of extrapulmonary tuberculosis. METHODS: 143 biological samples and tissues from patients with suspected extrapulmonary tuberculosis fro...

Functional performance of different venous limb options in simulated neonatal/pediatric cardiopulmonary bypass circuits

Abstract Objective: Hemodilution is a concern in cardiopulmonary bypass (CPB). Using a smaller dual tubing rather than a single larger inner diameter (ID) tubing in the venous limb to decrease prime volume has been a standard practice. The purpose of this study is to evaluate these tubing options. Meth...

Programa multicéntrico de cribado de cáncer colorrectal en Chile

Rev. méd. Chile; 146 (6), 2018
Background: Colorectal Cancer Screening Programs (CRCSP) are widely accepted in developed countries. Unfortunately, financial restrictions, low adherence rate and variability on colonoscopy standardization hamper the implementation of CRCSP in developing countries. Aim: To analyze a multicentric pilot m...

Ejercicio físico en pacientes con diabetes e hipertensión: prevalencia de respondedores y no respondedores para mejorar factores de riesgo cardiometabólicos

Rev. méd. Chile; 146 (6), 2018
Background: There is a wide interindividual variability in the response to a period of exercise training. The science have reported that a minimum of participants could be non-responders for improving different health-related outcomes after training. Aim: To compare the effects of a 6-weeks exercise pro...

Percepción de estudiantes de pregrado de Medicina de talleres de simulación de procedimientos médico-quirúrgicos

Rev. méd. Chile; 146 (6), 2018
Background: Simulation is a useful training tool for undergraduate medical students. A valid instrument is needed to assess students' perception of simulation workshops. Aim: To adapt and validate an instrument to assess the undergraduate medical student's perception of simulation workshops of clinical ...

Adsorción extracorpórea de citoquinas en el tratamiento del shock séptico refractario: casos clínicos

Rev. méd. Chile; 146 (6), 2018
If Septic shock (SS) evolves to refractory SS, mortality could reach 90%, despite giving an optimal treatment. Nowadays, extracorporeal devices which adsorb inflammatory cytokines are available, reducing the systemic inflammatory response syndrome. These devices can be used with continuous renal replacem...

Pulmonary Ultrasound in Patients with Heart Failure - Systematic Review

Arq. bras. cardiol; 110 (6), 2018
Abstract Pulmonary congestion is an important clinical finding in patients with heart failure (HF). Physical examination and chest X-ray have limited accuracy in detecting congestion. Pulmonary ultrasound (PU) has been incorporated into clinical practice in the evaluation of pulmonary congestion. This pa...

Pressure Overload-induced Cardiac Hypertrophy Varies According to Different Ligation Needle Sizes and Body Weights in Mice

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: The cardiac hypertrophy (CH) model for mice has been widely used, thereby providing an effective research foundation for CH exploration. Objective: To research the effects of CH modeling under abdominal aortic constriction (AAC) using different needles and weights in mice. Methods...

A curcumin derivative J147 ameliorates diabetic peripheral neuropathy in streptozotocin (STZ)-induced DPN rat models through negative regulation AMPK on TRPA1

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the specific molecular mechanisms and effects of curcumin derivative J147 on diabetic peripheral neuropathy (DPN). Methods: We constructed streptozotocin (STZ)-induced DPN rat models to detected mechanical withdrawal threshold (MWT) in vivo using Von Frey filaments. I...
