Impact of delirium on post-discharge mortality in coronary care unit patients: A retrospective cohort study.

Background: Coronary care unit (CCU) patients surviving to discharge still face significant mortality. Delirium is common in CCU patients and has been associated with poorer CCU and in-hospital outcomes.

Aim: To assess the association between delirium and mortality after hospital discharge in CCU survivors.

Age affects vascular morphology and predictiveness of anatomical landmarks for aortic zones in trauma patients: implications for resuscitative endovascular balloon occlusion of the aorta.

Purpose: Understanding the vascular morphology is fundamental for resuscitative endovascular balloon occlusion of the aorta. This study aimed to evaluate the effect of aging on length and diameter of aorta and iliac arteries in trauma patients, and to investigate the predictiveness of anatomical landmarks for aortic zones.

Methods: A total of 235 patients in a regional trauma center registry from September 1, 2018, to January 3, 2024, participated in the study.

Effect of tiotropium on neural respiratory drive during exercise in severe COPD.

Background: Studies have shown that tiotropium once daily reduces lung hyperinflation and dyspnea during exercise and improves exercise tolerance in patients with COPD. Mechanisms underlying the effects of the muscarinic receptor antagonist tiotropium on COPD have not been fully understood.

Objective: In this study, we investigated whether improvement in neural respiratory drive is responsible for reducing dyspnea during exercise and improving exercise tolerance in COPD.

[Neural respiratory drive in patients with obstructive sleep apnea].

Objective: To evaluate the variability of neural respiratory drive in patients with obstructive sleep apnea (OSA) and the effect of continuous positive airway pressure (CPAP) upon neural respiratory drive.

Methods: We recorded diaphragm electromyogram (EMGdi) with multi-pair esophageal electrodes and its variability during wakefulness, sleep and treatment with CPAP in 13 patients with moderate to severe OSA diagnosed by an overnight full polysomnography (OSA group). Six normal subjects (control group) were also studied.
