Obstructive sleep apnea is associated with worse clinical-radiological risk scores of pulmonary embolism.

Obstructive sleep apnea is a risk factor for pulmonary embolism, although its association with pulmonary embolism severity is unknown. Our objective was to study if obstructive sleep apnea is associated with worse pulmonary embolism severity scores and greater extent of arterial obstruction. In consecutive pulmonary embolism patients, we performed respiratory polygraphy and recorded sleep characteristics, classical risk factors for pulmonary embolism and physical activity 6-12 months after the pulmonary embolism episode.

[Prevalence of osteoporosis, estimation of probability of fracture and bone metabolism study in patients with newly diagnosed prostate cancer in the health area of Lugo].

Objective: To study the prevalence of osteoporosis and fracture probability in patients diagnosed with prostate cancer.

Design: Observational descriptive transversal study. SITE: Study performed from Primary Care of Lugo in collaboration with Rheumatology and Urology Services of our referral hospital.

OSA Is a Risk Factor for Recurrent VTE.

Background: OSA is a risk factor for a first episode of pulmonary embolism (PE), although its impact on the risk of thromboembolism recurring is uncertain. Our objective was to explore the prognostic value of OSA after the discontinuation of oral anticoagulation (OAC) in patients with a first episode of PE.

Methods: In 120 consecutive patients who had stopped OAC for a first episode of PE, we performed home respiratory polygraphy and recorded sleep characteristics, classic risk factors for PE, blood pressure measurements, spirometric parameters, physical activity, and levels of D-dimer and prothrombin fragment 1+2 (F1+2).

High D-dimer levels after stopping anticoagulants in pulmonary embolism with sleep apnoea.

Obstructive sleep apnoea is a risk factor for pulmonary embolism. Elevated D-dimer levels and other biomarkers are associated with recurrent pulmonary embolism. The objectives were to compare the frequency of elevated D-dimer levels (>500 ng·mL(-1)) and further coagulation biomarkers after oral anticoagulation withdrawal in pulmonary embolism patients, with and without obstructive sleep apnoea, including two control groups without pulmonary embolism.

Effectiveness of three sleep apnea management alternatives.

Rationale: Home respiratory polygraphy (HRP) may be a cost-effective alternative to polysomnography (PSG) for diagnosis and treatment election in patients with high clinical probability of obstructive sleep apnea (OSA), but there is conflicting evidence on its use for a wider spectrum of patients.

Objectives: To determine the efficacy and cost of OSA management (diagnosis and therapeutic decision making) using (1) PSG for all patients (PSG arm); (2) HRP for all patients (HRP arm); and (3) HRP for a subsample of patients with high clinical probability of being treated with continuous positive airway pressure (CPAP) and PSG for the remainder (elective HRP arm).

Methods: Multicentric study of 366 patients with intermediate-high clinical probability of OSA, randomly subjected to HRP and PSG.

Association between obstructive sleep apnea and pulmonary embolism.

Objectives: To compare the prevalence of obstructive sleep apnea (OSA) in patients with pulmonary embolism (PE) with a sex-, age-, and body mass index (BMI)-matched, population-based control group and to assess the association between OSA and PE.

Methods: We performed a case-control study from October 1, 2006, through November 30, 2009. We included 107 patients with PE and a control group (n=102) without PE in University Hospitals Son Espases and La Paz in Spain.

Significance of including a surrogate arousal for sleep apnea-hypopnea syndrome diagnosis by respiratory polygraphy.

Rationale: Respiratory polygraphy is an accepted alternative to polysomnography (PSG) for sleep apnea/hypopnea syndrome (SAHS) diagnosis, although it underestimates the apnea-hypopnea index (AHI) because respiratory polygraphy cannot identify arousals.

Objectives: We performed a multicentric, randomized, blinded crossover study to determine the agreement between home respiratory polygraphy (HRP) and PSG, and between simultaneous respiratory polygraphy (respiratory polygraphy with PSG) (SimultRP) and PSG by means of 2 AHI scoring protocols with or without hyperventilation following flow reduction considered as a surrogate arousal.

Methods: We included suspected SAHS patients from 8 hospitals.

Effectiveness of home respiratory polygraphy for the diagnosis of sleep apnoea and hypopnoea syndrome.

Introduction: Home respiratory polygraphy (HRP) may be a cost-effective alternative to polysomnography for the diagnosis of sleep apnoea-hypopnoea syndrome (SAHS), but stronger evidence is needed. Normally, patients transport HRP equipment from the hospital to home and back, which may create difficulties for some patients.

Objectives: To determine both the diagnostic efficacy and cost of HRP (with and without a transportation service moving the device and telematic transmission of data) in a large sample compared with in-hospital polysomnography.

A controlled trial of noninvasive ventilation for chronic obstructive pulmonary disease exacerbations.

Purpose: This prospective, multicenter, double-blind, placebo-controlled study tested the hypothesis that noninvasive positive pressure ventilation reduces the need for endotracheal intubation in patients hospitalized in a pulmonary ward because of acute exacerbation of chronic obstructive pulmonary disease.

Materials And Methods: Seventy-five consecutive patients with exacerbation (pH, 7.31 +/- 0.

[Activity of an intermediate respiratory care unit attached to a respiratory medicine department].

Background And Objective: With the development of noninvasive ventilation (NIV), patients with increasingly complex needs have been admitted to respiratory medicine departments. For this reason, such departments in Spain and throughout Europe have been adding specialized respiratory intermediate care units (RICUs) for monitoring and treating patients with severe respiratory diseases. The aim of the present study was to describe the activity of such a RICU.

[Impact of an on-duty pulmonologist on the activity of a respiratory medicine department].

Objective: To evaluate the impact on health care and clinical management of 24-hour coverage by an on-site pulmonologist in a respiratory medicine department.

Methods: In February 2004, a new respiratory medicine 24-hour duty service was started in our hospital. The activity of the on-duty pulmonologist during the following 12 months was systematically and prospectively recorded.

Systemic inflammation after inspiratory loading in chronic obstructive pulmonary disease.

Objective: Patients with chronic obstructive pulmonary disease (COPD) present systemic inflammation. Strenuous resistive breathing induces systemic inflammation in healthy subjects. We hypothesized that the increased respiratory load that characterizes COPD can contribute to systemic inflammation in these patients.
