Upcoming Scenarios for the Comprehensive Management of Obstructive Sleep Apnea: An Overview of the Spanish Sleep Network / Escenarios futuros en el manejo integral de la apnea obstructiva del sueño: perspectiva del Spanish Sleep Network

Sleep is considered an essential part of life and plays a vital role in good health and well-being. Equally important as a balanced diet and adequate exercise, quality and quantity of sleep are essential for maintaining good health and quality of life. Sleep-disordered breathing is one of the most prevalent conditions that compromises the quality and duration of sleep, with obstructive sleep apnea (OSA) being the most prevalent disorder among these conditions. OSA is a chronic and highly prevalent disease that is considered to be a true public health problem. OSA has been associated with increased cardiovascular, neurocognitive, metabolic and overall mortality risks, and its management is a challenge facing the health care system. To establish the main future lines of research in sleep respiratory medicine, the Spanish Sleep Network (SSN) promoted the 1st World Café experts' meeting. The overall vision was established by consensus as "Sleep as promoter of health and the social impact of sleep disturbances". Under this leitmotiv and given that OSA is the most prevalent sleep disorder, five research lines were established to develop a new comprehensive approach for OSA management: (1) an integrated network for the comprehensive management of OSA; (2) the biological impact of OSA on comorbidities with high mortality, namely, cardiovascular and metabolic diseases, neurocognitive diseases and cancer; (3) Big Data Analysis for the identification of OSA phenotypes; (4) personalized medicine in OSA; and (5) OSA in children: current needs and future perspectives

El sueño se considera una parte esencial de la vida y es vital para una buena salud y para el bienestar. De igual importancia que una dieta equilibrada y una adecuada actividad física, la calidad y la cantidad del sueño son esenciales para mantener una buena salud y calidad de vida. Las alteraciones respiratorias del sueño son los trastornos más prevalentes que comprometen la calidad y duración del sueño, siendo el síndrome de la apnea obstructiva del sueño (SAHS) el más frecuente. El SAHS es una enfermedad de elevada prevalencia que se considera un problema de salud pública. Se ha asociado con aumento del riesgo cardiovascular, neurocognitivo, metabólico y especialmente de mortalidad, y su manejo representa un reto para el sistema de salud. Para establecer las principales líneas futuras de investigación en medicina respiratoria del sueño, el Spanish Sleep Network promovió la primera edición del World Cafe experts' meeting. El mensaje principal «El sueño como promotor de la salud y el impacto social de los trastornos del sueño» se estableció por consenso. Bajo este lema y dado que el SAHS es el trastorno del sueño más prevalente, se establecieron cinco líneas de investigación para desarrollar una aproximación completa para el manejo de este síndrome: 1) Una red integrada para el manejo del SAHS; 2) El impacto biológico del SAHS en las comorbilidades con elevada mortalidad como la enfermedad cardiovascular, las enfermedades metabólicas y neurocognitivas y el cáncer; 3) El análisis de grandes bases de datos para la identificación de fenotipos del SAHS; 4) Medicina personalizada en el SAHS, y 5) El SAHS en niños: necesidades actuales y perspectivas futuras

Obstructive sleep apnea and nocturnal hypoxemia are associated with an increased risk of lung cancer.

STUDY OBJECTIVES: To identify a link between sleep disordered breathing, nocturnal hypoxemia, and lung cancer. METHODS: We conducted a cross-sectional study of a combined cohort of 302 individuals derived from the sleep apnea in lung cancer study (SAIL; NCT02764866) investigating the prevalence of sleep apnea in lung cancer, and the sleep apnea in lung cancer screening study (SAILS; NCT02764866) investigating the prevalence of sleep apnea in a lung cancer screening program. All subjects had spirometry and a chest CT, underwent home sleep apnea testing (HSAT), and completed a sleep related questionnaire. Subjects from the SAIL study underwent HSAT prior to initiating oncologic therapy or surgery. Subjects with an apnea-hypopnea index (AHI) > 15 were compared with a control group of individuals with an AHI < 15. Propensity score, near neighbor matching, and logistic regression adjusted for potential confounders, were used in order to evaluate the association between sleep apnea, the AHI, oxygen desaturation indices and lung cancer. RESULTS: The prevalence of sleep apnea and lung cancer in the combined cohort was 42% and 21%, respectively. Lung cancer was 8% more prevalent in patients with an AHI >15. The difference was statistically significant when assessed by propensity score matching (p = 0.015) and nearest neighbor matching (p = 0.041). Binary logistic regression adjusted for potential confounders revealed a statistically significant association between AHI (p = 0.04), nocturnal hypoxemia, including time spent below 90% oxyhemoglobin saturation (T90%; p = 0.005), 3% oxygen desaturation index (ODI3; p = 0.02) and lung cancer. CONCLUSIONS: Sleep apnea and nocturnal hypoxemia are associated with an increased prevalence of lung cancer. CLINICAL TRIAL REGISTRATION: SAIL study (NCT02764866) and SAILS study (NCT02764866).

Sleep Disordered Breathing Is Highly Prevalent in Patients with Lung Cancer: Results of the Sleep Apnea in Lung Cancer Study.

BACKGROUND: Obstructive sleep apnea (OSA) has been linked to tumorigenesis and tumor progression. OBJECTIVES: The Sleep Apnea in Lung Cancer (SAIL) study (NCT02764866) was designed to determine the prevalence of OSA in patients with lung cancer. METHODS: Cross-sectional study including consecutive patients with newly diagnosed lung cancer. All patients were offered home sleep apnea testing (HSAT) and administered a sleep-specific questionnaire prior to initiating oncologic treatment. Sleep study-related variables, symptoms, and epidemiologic data as well as cancer related variables were recorded. RESULTS: Eighty-three patients were enrolled in the SAIL study. Sixty-six completed HSAT. The mean age was 68 ± 11 years and 58% were male with a mean body mass index of 28.1 ± 5.4. Forty-seven percent were current smokers, 42% former smokers, and 11% never smokers with a median tobacco consumption of 51 pack-years. Fifty percent had COPD with a mean FEV1 of 83 ± 22.6% of predicted and a mean DLCO of 85.5 ± 20.1%. Adenocarcinoma was the most common histologic type (46.7%), followed by squamous cell (16.7%) and small cell (16.7%). Most patients were diagnosed at an advanced stage (65% in stages III-IV). The vast majority (80%) had OSA (apnea-hypopnea index [AHI] > 5), and 50% had moderate to severe OSA (AHI > 15) with a mean Epworth Sleepiness Score of 7.43 ± 3.85. Significant nocturnal hypoxemia was common (Median T90: 10.9% interquartile range 2.4-42.2). CONCLUSIONS: Sleep apnea and nocturnal hypoxemia are highly prevalent in patients with lung cancer.
