  1. 1. Correlated random effects models for clustered survival data

    Författare :Frank Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; competing risks; case-cohort; semiparametric; Survival analysis; random effects; routine register; frailty model; Survival analysis; frailty model; competing risks; random effects; case-cohort; routine register; semiparametric;

    Sammanfattning : Frailty models are frequently used to analyse clustered survival data in medical contexts. The frailties, or random effects, are used to model the association between individual survival times within clusters. LÄS MER

  3. 2. Physical activity, visceral adipose tissue, and cardiovascular disease in older adults : associations and effects

    Författare :Marcel Ballin; Peter Nordström; Johan Niklasson; Maria Hagströmer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; exercise; obesity; stroke; myocardial infarction; death; aging; geriatrics; epidemiology; trial; Geriatrics; geriatrik; epidemiologi; Epidemiology; kardiologi; Cardiology; Public health; folkhälsa; physiotherapy; fysioterapi;

    Sammanfattning : BACKGROUND: Cardiovascular disease (CVD) poses a substantial public health burden and is the leading cause of mortality in older adults. With the population aging rapidly, interventions aimed at improving modifiable risk factors for CVD, such as physical inactivity and visceral obesity, could play an important role in reducing its burden, provided they are proven effective.

  4. 3. Adverse effects of psychotropic drugs in old age

    Författare :Jon Brännström; Hugo Lövheim; Yngve Gustafson; Peter Nordström; Patrik Midlöv; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Geriatric medicine; psychotropic drugs; adverse effects; mortality; hip fracture; cohort study; old age; Geriatrics; geriatrik;

    Sammanfattning : Background: With increasing age, the body and mind transform. Many of our organs gradually lose capacity, making them more sensitive to the effects of several drugs. In parallel, many of us accumulate an increasing burden of disease and other conditions warranting the use of medications. LÄS MER

  5. 4. Cardiovascular and pulmonary health effects of air pollution - long term effects in Sweden and effects of wood smoke

    Författare :Leo Stockfelt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; wood smoke; human exposure studies; dispersion modelling; cohort studies; cardiovascular disease;

    Sammanfattning : Exposure to air pollution is associated with increased morbidity and mortality in cardiovascular and pulmonary diseases. Main suggested mechanisms are airway and systemic inflammation, affecting hemostasis in the short term and atherosclerosis in the long term. LÄS MER

  7. 5. Assessment of cognition in ageing. Investigating internal validity, occurrence and reversion of Mild Cognitive Impairment. Data from the general population study “Good Aging in Skåne”

    Författare :Marie Claire Overton; Geriatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ageing; Older adults; Cognition; validity; test administrator effects; cohort effects; Mild cognitive impairment;

    Sammanfattning : Given a growing population of older adults and the common occurrence of natural as well as pathological cognitive decline, i.e. dementia, there is a need to better understand how to accurately measure and classify level of cognitive functioning. LÄS MER
