Nocturnal oxygen therapy in patients with chronic heart failure and sleep apnea: a systematic review.

Chronic heart failure (CHF) is a public health problem which affects >2% of the adult population, with high morbidity, mortality, and financial cost. Sleep apnea, prevalent in >50% of patients with CHF, can aggravate vital prognosis due to worsening of heart failure. It is considered that a decrease in the apnea-hypopnea load may improve outcomes for those patients.

Short- and long-term effects of nocturnal oxygen therapy on sleep apnea in chronic heart failure.

Purpose: This paper studies the short- and long-term effects of nocturnal oxygen therapy (NOT) on sleep apnea in chronic heart failure (CHF).

Methods: We enrolled 51 adults in New York Heart Association (NYHA) heart failure functional classes II or III, ≤45 % left ventricular ejection fraction (LVEF), in a randomized, open, single-center study. Nocturnal cardiorespiratory polygraphy showed sleep apnea [apnea-hypopnea index (AHI) ≥15 events/h] in 33 patients, of whom 19 were randomly assigned to NOT, 3.

Characteristics of prosthetic joint infections leading to bacteremia: a case-control study.

The possible systemic infectious consequences of prosthetic joint infections (PJI) are poorly documented in the literature. We assessed the frequency of postoperative prosthetic hip and knee infections leading to bacteremia and investigated their associated factors among patients treated between 2005 and 2009. Among 633 patients with PJI, 62 (9.
