Effect of respiratory muscle training in patients with stable chronic obstructive pulmonary disease: A systematic review and meta-analysis.

Objectives: Chronic obstructive pulmonary disease (COPD) is a prevalent respiratory disorder characterized by progressive airflow limitation. This meta-analysis aims to evaluate the effectiveness of respiratory muscle training (RMT) on key pulmonary function parameters, inspiratory muscle strength and quality of life in patients with stable COPD.

Methods: A comprehensive search was conducted in the databases including PubMed, Cochrane, Web of Science, Embase, and ClinicalTrials.

Difference in meal-related esophageal intraluminal impedance change between gastroesophageal reflux disease and functional disorders.

Objectives: Gastroesophageal reflux disease (GERD) has overlapping symptoms with functional disorders such as functional heart burn. Twenty-four-hour pH with impedance monitoring is useful for differentiation. The intraluminal impedance change with meal in distal esophagus is not investigated.

High Dose of Atorvastatin for the Treatment of Contrast-Induced Nephropathy After Carotid Artery Stenting.

Statins have been used to prevent contrast-induced nephropathy (CIN). However, the optimal dose of statins is still under controversy. This study aimed to investigate the optimal dose of atorvastatin for the treatment of CIN after carotid artery stenting (CAS).
