[Risk factors for mortality in patients with chronic obstructive pulmonary disease].

Objective: To identify risk factors of mortality in patients with chronic obstructive pulmonary disease (COPD).

Design: A retrospective cohort study.

Location: Primary care setting in Lleida, Spain.

[Factors associated with influenza immunization in primary care health workers].

Objective: To identify the influenza vaccination coverage in healthcare workers in primary care and to determine the factors associated with vaccination (2013-2014 season).

Methods: A cross-sectional study was carried out among 287 healthcare workers who completed a questionnaire that included questions about knowledge, beliefs and attitudes to influenza and vaccination. We estimated the vaccine coverage and identified the variables associated with vaccination of healthcare workers by using non-conditional logistic regression models.

Corneal biomechanical properties in floppy eyelid syndrome.

Purpose: To determine corneal biomechanical properties in patients with floppy eyelid syndrome (FES) and to compare them with eyes of controls.

Methods: This case-control study included 208 eyes (72 eyes with FES and 136 without FES) of 107 patients (37 patients with FES and 70 without FES). Patients underwent a complete clinical eye examination that included corneal biomechanical evaluation carried out with the Reichert Ocular Response Analyzer.

Obstructive sleep apnea/hypopnea and systemic hypertension.

Obstructive sleep apnea/hypopnea (OSAH) syndrome is a highly prevalent condition. Severe OSAH affects 2-6% of the population, although only 10% of subjects are correctly diagnosed and treated. OSAH is an important and unresolved public health care problem because of its role in the development of cardiovascular events, negative impact on quality of life, and as a cause of traffic accidents.

Continuous positive airway pressure treatment reduces mortality in patients with ischemic stroke and obstructive sleep apnea: a 5-year follow-up study.

Rationale: Obstructive sleep apnea (OSA) is an independent risk factor for stroke, but little is known about the role of continuous positive airway pressure (CPAP) on mortality in patients with stroke.

Objectives: To analyze the independent impact of long-term CPAP treatment on mortality in patients with ischemic stroke.

Methods: Prospective observational study in 166 patients with ischemic stroke.

[Resources and delays in the diagnosis of sleep apnea-hypopnea syndrome].

Objective: The demand for consultations and diagnostic studies for sleep apnea-hypopnea syndrome (SAHS) has increased, and this has led to considerable delays. We therefore need an updated evaluation of the diagnostic situation to serve as a management tool for specialists and health care administrations responsible for solving the problem. The objective of the present study was to carry out a descriptive analysis of the situation regarding the diagnosis of SAHS in Spanish hospitals.
