1. 1. Intraocular pressure : clinical aspects and new measurement methods

   Författare :Gauti Jóhannesson; Christina Lindén; Per Hallberg; Anders Eklund; Boel Bengtsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intraocular pressure; glaucoma; tonometry; ISO; LASEK; CCT; curvature; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

   Sammanfattning : Intraocular pressure (IOP) measurement is a routine procedure and a fundament in glaucoma care. Elevated IOP is the main risk factor for glaucoma, and to date, reduction of IOP is the only possible treatment. In a retrospective clinical material, the prevalence of open angle glaucoma was estimated on the west coast of Iceland. LÄS MER

3. 2. Pressure sores : risk assessment and prevention

   Författare :Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.

4. 3. "Under pressure" : interaction between pharmaceuticals and river bacteria

   Författare :Aleksandra Hagberg; Madeleine Ramstedt; Mette Burmølle; Jerker Fick; Rikke Louise Meyer; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biofilms; river bacteria; pharmaceutical contamination;

   Sammanfattning : Pharmaceuticals are often entering the environment without being completely decomposed. Once released in the environment they continue to carry on their main function but instead targeting the inhabitants of the aquatic ecosystem. Our interest was drawn towards the bacteria, that are often present in the environment in the form of biofilms. LÄS MER

5. 4. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

   Författare :Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 5. Pressure Ulcer Prevention : Performance and Implementation in Hospital Settings

   Författare :Eva Sving; Lena Gunningberg; Marieann Högman; Anna-greta Mamhidir; Helle Wijk; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer prevention; nursing care; implementation; Trycksårsprevention; omvårdnad; implementering; Omvårdnadsforskning med samhällsvetenskaplig inriktning; Caring Sciences in Social Sciences;

   Sammanfattning : Background: Pressure ulcers are related to reduced quality of life for patients and high costs for health care. Guidelines for pressure ulcer prevention have been available for many years but the problem remains. LÄS MER
