The present study examined the neuropsychological relevance of poor sleep in a sample of community dwelling healthy older adults and a clinical sample of patients with untreated obstructive sleep apnea (OSA) between 40 and 90 years of age. The cognitive performance of 67 patients with obstructive sleep apnea (OSA) was compared to those of 46 controls screened for OSA using a portable device called ApneaLinkTM. The current study identified common neuropsychological variables associated with poor sleep quality in general (i.e., as a result of daytime sleepiness) and neuropsychological variables unique to only OSA patients (i.e., manifesting oxygen desaturation at night in addition to daytime sleepiness). Results indicated executive functions were related to hypoxemia and sustained attention was related to sleep fragmentation in the current study. A medical sequelae model and a neuropsychological sequelae model were tested. The neuropsychological sequelae model predicted whether one was a control or an OSA patient 70% accurately based on the predictors (scores on Wisconsin Card Sorting Test perseverance error, vigilance task, WAIS III forward digit span, WAIS III Block Design, phonemic and semantic fluency, and WAIS III backward digit span). The medical sequelae model predicted OSA status 89% accurately based on the predictors (BMI, depression, subjective sleep quality, age, hypertension, diabetes, total mood disturbance, gender, and general health). The current study provides further justification for OSA screening in the general population during middle age and late adulthood especially in those most at risk (i.e., overweight, male, hypertensive, and poor subjective sleep quality).

Introduction Chronic obstructive pulmonary disease (COPD) has emerged as a major policy focus for health systems throughout Western Europe. This reflects the increased prevalence, associated healthcare utilisation and costs of COPD, and the potential to substantially improve outcomes through achieving reductions in smoking. The aim of this PhD was to develop projections for the prevalence, healthcare costs and number of deaths in people with COPD in England and Scotland over a 20-year horizon (i.e. from 2011 to 2030). Methods I undertook a phased programme of work, which began with a systematic review of the published and unpublished literature to identify models that were suitable for estimating and/or projecting the prevalence and disease and economic burden from COPD. This involved searching Medline, Embase, CAB Abstracts, World Health Organization (WHO) Library and Information Services and WHO Regional Indexes, and Google over the time period 1980-2013. The models were then critically appraised for their quality of reporting. From these, I selected the Dutch Model developed by Erasmus University for generating projections. Suitable data sources from both England and Scotland were identified, sourced and carefully processed in order to run the modelling exercises. Rates of incidence and prevalence were calculated using English and Scottish healthcare datasets and population data were obtained from the Office for National Statistics (ONS) and the General Register Office for Scotland (GROS). Relative risks for all-cause mortality among people with COPD were calculated from the Clinical Practice Research Datalink and mortality data were obtained from the ONS and GROS. The Model was thus adjusted to apply to England and Scotland. I then travelled to the Netherlands to work with the developers of the Dutch Model and ran a baseline model and an array of sensitivity analyses with modified inputs to the Model. Finally, my Rotterdam colleagues calculated uncertainty intervals for some of the estimates using probabilistic analysis. Results Using the probabilistic means and uncertainty intervals, in England, the modelled prevalence of diagnosed COPD among males of all ages in 2011 was 1.8% (95% uncertainty interval 1.8-1.9) increasing to 2.0% (1.7-2.1) by 2030. In females, in England, the baseline estimate was 1.8% (1.7-1.8) in 2011 increasing to 2.4% (2.0-2.6) in 2030. In Scotland, the modelled prevalence among males was 1.9% (1.8-1.9) in 2011 and this was projected to stay the same at 1.9% (1.7-2.2) by 2030. In females in Scotland, the estimated prevalence was 2.2% (2.1- 2.3) in 2011 and was projected to increase to 2.5% (2.1-2.7) in 2030.Using the Model I estimated that overall in 2011 there were a total of 952,000 (941,000-966,000) people with diagnosed COPD in England and 106,000 (103,000-110,000) in Scotland and that these numbers would increase to 1,325,000 (1,117,000-1,408,000) in England in 2030 and 125,000 (113,000-136,000) in Scotland in 2030, respectively. The greatest increase in COPD was projected to be in females over 65 years of age in both countries. The total annual direct healthcare costs of COPD in England were projected to increase from £1.60 (95% uncertainty interval 1.18-2.5) billion in 2011 to £2.35 (1.85-3.08) billion in 2030. In Scotland, costs were projected to increase from £170 (128-268) million in 2011 to £210 (165-274) million in 2030. These costs were calculated in terms of 2011 costs without the application of any economic trends (i.e. no annual increase applied for inflation). The number of deaths among people with COPD in England was estimated to be 99,000 (93,000-129,000) in 2011, increasing to 129,000 (126,000-133,000) in 2030. In Scotland there were estimated to be 10,000 (9,000-12,000) deaths in 2011, increasing to 14,000 (13,000-15,000) in 2030. The Dutch Model demonstrated a 39% increase in the number of people with COPD in England and a 17% increase in Scotland between 2011 and 2030. It provided an estimate of a 30% increase in deaths among people with COPD in England and of a 43% increase in Scotland. Overall, there was a projected 46% increase in the direct healthcare costs required to care for people with COPD in England and a 23% increase in Scotland between 2011 and 2030. The reasons for these differences are largely due to higher COPD-related excess mortality in Scotland and to differences in the data used for populating the model in both countries. Conclusions There are likely to be substantial increases in the number of people with COPD, associated morbidity, direct healthcare costs and mortality in both England and Scotland over the next two decades. These increases in numbers will predominantly occur in females over 65 years of age and are likely to have substantial societal impact in terms of organising the health and social care for this frail population.

So, the exercise has become important in the process of rehabilitation. Objective: To evaluate the effectiveness of a program of resistance training with elastic band in peripheral muscle strength, functional capacity and quality of life of patients with COPD. Methods: We evaluated 34 patients (24 men, 10 women) with COPD, age 62 ± 8.27 years and BMI 21.29 ± 3.73 divided into two groups: conventional resistance training and with elastic band for the period of eight weeks and frequency of three times weekly. Peripheral muscle strength was assessed with a dynamometer, the functional capacity for the six-minute walking test and quality of life for the Chronic Respiratory Questionnaire (CRQ). Results: the assessment of peripheral muscle strength had improved in both groups for all muscle groups exercised during the protocol. Performance on the 6MWT (meters) showed improvement after eight weeks of training, both in the elastic band... (Complete abstract click electronic access below) / Mestre

Abstract Seventy-eight prepubertal children 3 to 10 years old (mean age 5,67 years, range 2.4 - 10.5 years), with symptoms suggestive of obstructive sleep apnea syndrome (OSAS) were studied. Based on overnight polysomnography (PSG) results, 32 children were classified as having OSAS, whereas 46 children were considered as primary snorers (PSs'), when an obstructive apnea-hypopnea index (AHIO) of over one was considered abnormal. Symptoms, signs and findings in these two groups were compared in a cross-sectional study. Fifty-eight of the children were retrieved for a follow-up visit, which was scheduled six months from the first visit. The children with an initial AHIO of 2 or over (n = 21) had been subjected to adenotonsillectomy swiftly after the first visit, whereas the others (n = 37) were observed without intervention. The changes in symptoms, signs and findings were analysed within and between these groups. Relative risk (RR) ratios were calculated in order to find clinical symptoms and signs predicting OSAS in snoring children. Observed apneas, restless sleep, constant snoring and tonsillar hypertrophy were significantly associated with an increased risk of OSAS. Dental arch measurements indicated that AHIO was significantly associated with the amount of overjet, suggesting that altered breathing may affect the dentofacial morphology. Nasalance measurements revealed no group differences between the OSAS children and PSs'. Adenotonsillectomy had no significant influence on the nasalence scores. Measurements of nasalance seem to contribute little to the diagnostics of OSAS in children. At the first visit the mean circulating concentrations of insulin-like growth factor-1 (IGF-1) were of the same magnitude in the OSAS children, the PSs' and the age-matched control group, but both the OSAS children and the PSs' had lower IGF-binding protein-3 (IGFBP-3) concentrations than the control subjects. At the second visit a significant increase of the peripheral concentrations of IGF-1 and IGFBP-3, along with increases in weight for height and BMI were observed in the surgically treated children, whose respiratory parameters and symptoms had improved highly significantly, as well. These results indicate that the growth of children with obstructed nighttime breathing is potentially affected through impaired growth hormone secretion. None of the primary snorers developed OSAS during the observation period, which finding suggests a favorable prognosis for primary snoring in children.
