  2. 1. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Author : Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer; photoplethysmography; laser Doppler flowmetry; non-invasive; tissue blood flow; reactive hyperemia; pressure-induced vasodilation; interface pressure; risk assessment;

    Abstract : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.

  4. 2. Risk factors for atrial fibrillation in population-based studies : Epidemiological perspectives

    Author : Linda Johnson; Internmedicin - epidemiologi; []
    Keywords : Atrial fibrillation; Fasting plasma insulin; forced expiratory volume; glucose; hypertension; lung volumes; population; premature atrial contractions; risk factors; spirometry; supraventricular extrasystoles; supraventricular tachycardias systolic blood pressure; weight;

    Abstract : Atrial fibrillation (AF) is common among the elderly, and has serious consequences such as stroke and increased mortality. Not all of the population attributable risk for AF is explained by known risk factors. READ MORE

  5. 3. Idiopathic normal pressure hydrocephalus : epidemiology and diagnostics

    Author : Johanna Andersson; Katarina Laurell; Jan Malm; Per Kristian Eide; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; idiopathic normal pressure hydrocephalus; epidemiology; prevalence; gait disorders; neuroimaging cognitive impairment; urinary incontinence; quality of life; depression;

    Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a progressive neurological condition characterized by a deterioration of gait, cognition, and continence. The diagnosis is based on a combination of enlarged ventricles seen in neuroimaging, with typical clinical findings. iNPH often affects elderly individuals (i.e. READ MORE

  6. 4. High Blood Pressure in Children with Hydronephrosis

    Author : Ammar Nadhom Farman Al-Mashhadi; Mattias Carlström; Gundela Holmdahl; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood pressure; hydronephrosis; hypertension; ambulatory blood pressure monitoring; nitric oxide; oxidative stress; pelvo-ureteric junction obstruction.; Barnkirurgi; Pediatric Surgery;

    Abstract : The most common cause of secondary hypertension is intrinsic renal disease, but little is known about the influence of hydronephrosis on blood pressure. In this thesis, the risk of development of hypertension in children with hydronephrosis was studied. READ MORE

  7. 5. Risk factors for cardiovascular events and incident hospital-treated diabetes in the population

    Author : Payam Khalili; Peter Nilsson; Johan Jendle; Annika Rosengren; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adiponectin; blood pressure; cardiovascular risk; diabetes; inflammation; pulse pressure; sialic acid; smoking; Medicin; Medicine;

    Abstract : Background: Cardiovascular disease (CVD) is the leading cause of death worldwide. Well-established risk factors for CVD include increasing age, male sex, sedentary lifestyle, obesity, smoking, diabetes, hypertension, dyslipidaemia and low socio-economic status. Traditional risk factors do, however, not fully explain cardiovascular risk in general. READ MORE
