- Características clínicas e polissonográficas de doentes com distúrbio respiratório do sono em REMPublication . Loureiro, CC; Drummond, M; Winck, JC; Almeida, JThere is a 10 -36% rate of obstructive sleep apnoea syndrome (OSAS) associated with rapid eye movement (REM) in the OSAS population. Prior studies have suggested an increased prevalence of psychiatric disorders and an effect of gender and age on these patients. Our aim was to study the clinical and polysomnograph (PSG) characteristics of our patients with REM- -related sleep disordered breathing (REM SDB). Inclusion criteria was the identification of REM SDB detected by PSG defined as apnea -hypopnea index (AHI) in REM sleep > or = 5h, AHI in non -REM sleep (NREM) < or = 15h and REM/NREM AHI > or = 2. Several Sleep Disorders Questionnaire (SDQ) version 1.02 parameters were analysed. The study comprised 19 patients with a mean age of 54.0 (SD+/-13.97), a mean BMI of 29.01 (SD +/- 4.10) and a 0.58 female / male ratio. The mean Epworth Sleepiness Scale score was 12.74 (SD +/-4.86). Mean AHI was 9.16/h (SD 4.09); mean AHI in REM sleep 37.08/h (SD 25.87) and mean REM -AHI/NREM- -AHI 8.86 (SD 8.63). The anxiety disorder rate was 33.3%; 44.4% in females, 16.7% in males. The average deep sleep was 20.7% (SD 10.42) and REM sleep 15.45% (SD 9.96), with a sleep efficiency of 85.3 (SD 8.70). No significant statistical correlation was found between the REM/NREM AHI index and anxiety symptoms, daytime sleepiness and sleep quality (REM and deep sleep percentages). These patients differ from the general OSAS population: on average, they are not obese, there are a greater number of females affected and they do not present a very significant diurnal hypersomnia. Reduced deep sleep and increased REM sleep were also present versus general population data, and sleep efficiency was just below the normal limit. Anxiety disorders were more prevalent in this group than described for the general population (3%) and OSAS patients.
- Doença Pulmonar Obstrutiva Crónica em Portugal: estudoPneumobil (1995) e estudo de prevalência de 2002 revisitadosPublication . Cardoso, J; Ferreira, JR; Almeida, J; Santos, JM; Rodrigues, F; Matos, MJ; Gaspar, MBACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) has been a leading cause of morbidity and mortality worldwide, over the years. In 1995, the implementation of a respiratory function survey seemed to be an adequate way to draw attention to neglected respiratory symptoms and increase the awareness of spirometry surveys. By 2002 there were new consensual guidelines in place and the awareness that prevalence of COPD depended on the criteria used for airway obstruction definition. The purpose of this study is to revisit the two studies and to turn public some of the data and respective methodologies. METHODS: From Pneumobil study database of 12,684 subjects, only the individuals with 40+ years old (n = 9.061) were selected. The 2002 study included a randomized representative sample of 1,384 individuals with 35-69 years old. RESULTS: The prevalence of COPD was 8.96% in Pneumobil and 5.34% in the 2002 study. In both studies, presence of COPD was greater in males and there was a positive association between presence of COPD and older age groups. Smokers and ex-smokers showed a higher proportion of cases of COPD. CONCLUSIONS: Prevalence in Portugal is lower than in other European countries. This may be related to lower smokers' prevalence. Globally, the most important risk factors associated with COPD were age over 60 years, male gender and smoking exposure. All aspects and limitations regarding different recruitment methodologies and different criteria for defining COPD cases highlight the need of a standardized method to evaluate COPD prevalence and associated risks factors, whose results can be compared across countries, as it is the case of BOLD project.
