    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; railway vibration; noise; sleep disturbance; polysomnography; cardiovascular disease;

    Sammanfattning : Sleep is a vital component of good health, and sleep loss is associated with impaired cognition, decreased psychomotor performance, cardiovascular disease, adverse effects on endocrine and metabolic function, negative mood, impaired memory, and more. A growing burden of freight transportation on global railway networks will likely lead to an increase in nocturnal vibration and noise at nearby dwellings. LÄS MER

  7. 20. Collagenous colitis : A study of epidemiology, etiology, clinical features and treatment

    Författare :Johan Bohr; Robert Löfberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Collagenous colitis (CC) is characterised clinically by chronic watery diarrhoea and histopathologically by an increased submucosal collagen layer. An epidemiologic study of CC during 1984 to 1993 showed a female:male ratio of 9:1. The median age at diagnosis was 64 (28-78) years. The prevalence was 15. LÄS MER
