Background The World Health Organization has projected that by 2030, chronic obstructive pulmonary disease (COPD) will be the third-leading cause of mortality and seventh-leading morbidity worldwide. Acute exacerbations (AECOPD) are associated with an accelerated decline in lung function, diminished quality life, higher mortality. Accurate early detection acute enable management reduce Objective aim this study was to develop a prediction system using lifestyle data, environmental factors,...

Abstract Impaired lung function is associated with morbidity and mortality in the elderly. However, there a paucity of data regarding long-term effects particulate matter (PM) on among This study evaluated exposure-response relationship between ambient PM different indices elderly Taiwan. A cross-sectional survey individuals aged ≥65 years was conducted Taiwan from October 2015 to September 2016. Those who attended annual health examination for five hospitals varying background...

Objective: To investigate a new style of resistance exercise using elastic bands and explore its therapeutic effect on the lower-extremity function female patients with osteoarthritis (OA) knee. Design: A randomized, controlled clinical trial. Setting: University-affiliated medical center. Participants: Forty-one women mild-to-moderate knee OA were randomly assigned to one two groups, an group (n = 24; age: 65.0 ± 8.4 years), control 17; 70.8 years). Interventions: The performed supervised...

Abstract Loss of skeletal muscle mass is common with aging and can cause morbidity mortality in the elderly. The effects particulate air pollution on not known. study aims to assess chronic ambient fine particulates (PM 2.5 ) body composition From October 2015 November 2016, a cross-sectional survey 530 elderly (age > = 65 years) was conducted Taipei Basin, Taiwan. measured by bioelectrical impedance analysis (InBody 120). One year exposure estimated using Kriging method at participant’s...

Abstract Background Some evidences have shown the association between air pollution exposure and development of interstitial lung diseases. However, effect on progression restrictive ventilatory impairment diffusion capacity reduction is unknown. This study aimed to evaluate effects long-term ambient change rates total capacity, residual volume, among elderly. Methods From 2016 2018, single-breath helium dilution with carbon monoxide was performed once per year 543 elderly individuals....

<h3>Rationale and objectives</h3> Obliterative bronchiolitis (OB) is a rare disease with small number of established occupational aetiologies. We describe case series severe OB in workers making glass-reinforced plastics. <h3>Methods</h3> Workplace exposures were the likely cause after independent diagnosis two laying up fibreglass hulls yachts; second worker took over job first he left following lung transplant. Presentation these cases at international meetings led to others identifying...

Background Evidence suggests differences in clinical characteristics, causes, and prognoses between heart failure with reduced ejection fraction ( HF r EF ) preserved (HFpEF). Most studies have failed to support the prognostic relevance of anxiety or unclassified mean left ventricular <40%. Meanwhile, association p remains unexamined. This study compared value . Methods Results A total 158 patients (left fraction=28.51±7.53%) 108 HFpEF fraction=64.53±9.67%) were recruited May 2012 December...

Scatter and spatial resolution effects degrade the accuracy of radioactivity concentration estimates obtained from positron emission tomography (PET) data. We present evaluate a methodology for region quantification which accounts these degradations. The method is based on analysis sinogram data does not require dynamic sequences to be reconstructed. Moreover, variance are also produced may used define weights model analyses that use weighted least squares minimization in order obtain...

Med Biol. 10:83–86, 2009.—Cardiac muscle is a highly oxygenated tissue that produces ATP mainly from fat oxidation. However, when the rate of oxygen demand exceeds supply, energy reliance on carbohydrate substrate becomes crucial for sustaining normal cardiac function. In this study, effect acute altitude...
