Introduction Prevalence of planned pregnancies varies between countries but is often measured in a dichotomous manner. The aim of this study was to investigate to what level pregnant women had planned their pregnancies and whether pregnancy planning was associated with background characteristics and pregnancy-planning behavior. Material and methods A cross-sectional study that utilized the baselin
Popular Abstract in Swedish Det elektriska kraftsystemets uppgift är att ge konsumenter en säker och stabil energitillgång till lägsta möjliga kostnad. Sett ur ett ingenjörsperspektiv tillkommer några extra krav såsom att variationerna i spänning och frekvens skall vara acceptabla, samt att enstaka komponenters kapacitetsgränser ej överskrids. Om dessa krav ej uppfylls kan detta leda till leveransThis thesis deals with various aspects of coordinated voltage control in electric power systems. It consists of an introduction and six papers. The introduction contains a summary of the thesis and tutorials on voltage control and the search methods that have been applied. The first part deals with the coordination of cascaded tap changers in radial distribution feeders. A tuning rule for the con
Popular Abstract in Swedish Vakuum-assisterad sårläkning (VAC) är en relativt ny metod för att påskynda sårläkning där primär läkning av ett eller annat skäl inte skett. Inom hjärtkirurgin anses mediastiniten, en sårinfektion som uppstår i operationsorådet kring bröstbenet efter kirurgi, vara en av de tre mest allvarliga postoperativa komplikationerna. Trots att hjärtkirurgi nu även erbjudes till Poststernotomy mediastinitis is a devastating complication associated with median sternotomy, which occurs mainly after cardiac surgery. The optimal treatment is still controversial. The aim was to develop, describe and evaluate a surgical procedure consisting of vacuum-assisted closure (VAC) in combination with delayed primary closure in patients with mediastinitis. A porcine sternotomy wound mo
Popular Abstract in Swedish Vid det tillstånd som kallas för vattenskalle, hydrocephalus, uppstår övertryck innanför skallen på grund av att vätskan, som cirkulerar där inte kan dräneras. Redan efter andra världskriget började man sätta in shuntar för att avleda överskottsvätskan till andra hålrum i kroppen, hjärtats förmak eller bukhålan. Runt 1960 kom emellertid de första rapporterna om infektioCoagulase-negative staphyloccoci (CoNS) are the most frequently isolated micro-organisms from infected cerebrospinal fluid (CSF) shunts and temporary ventricular drainage catheters, used in modern neurosurgery. CoNS originate from the skinflora of the patient or the surgeon and gain access to the surface of the implant at the insertion, but the infection can erupt up to a year later or more. Immed
Popular Abstract in Swedish Många äldre patienter genomgår operationer vilket innebär ökade risker för komplikationer framförallt vid omfattande kirurgiska ingrepp. Operationer i bröstkorgen och bukhålan ger upphov till påtaglig smärta i efterförloppet under den sk postoperativa perioden. En otillräcklig smärtbehandling under denna tidsperiod kan leda till en ökad risk för hjärt-kärl- och lungkompPostoperative pain relief with opioids after major non-cardiac surgery may give rise to adverse effects. The fear of dangerous side effects may therefore limit the optimal use of different treatment modalities in surgical wards. Opioids can be administered alone as an intravenous infusion, or in combination with local anaesthetics as an epidural infusion. Both regimes can be tailored with a patien

A group of 129 infants were randomly assigned at birth to one of three feeding regimens: human milk (HM), cow's milk formula (CMF), or a casein hydrolysate formula (CHF). The formula-fed infants received no human milk until the fourth day of life, after which all infants w
Popular Abstract in Swedish Systemiska biomarkörer hos patienter med aortaaneurysm. Kroppspulsådern eller aorta är huvudstammen som för syrerikt blod från hjärtat till perifera delar av kroppen. Kroppspulsåderbråck (aneurysm) i buken kännetecknas av försvagning i kärlväggen som i sin tur leder till vidgning av kroppspulsådern. Aneurysm är fyra gånger vanligare hos män än hos kvinnor över 65 års ålAbdominal aortic aneurysm (AAA) develops in 3-6% of the population over 65 years and affects mainly men. AAA has a complex etiology involving inflammation, proteolysis, fibrinolysis and coagulation. The general aim of the present thesis was to study the associations between markers of inflammation, proteolysis, fibrinolysis and coagulation with aneurysm size and growth.

Ett antal superkontinenter har existerat under jordens 4.6 Ga ( miljarder år gamla ) historia. Utav dessa är superkontinenten Pangea, som betyder ”allt land”, den senaste och mest väldefinierade. Bildning och uppsprickning av superkontinenter drivs av plattektoniska processer som i sin tur beror på strömningar ( konvektion ) i jordens mantel. Förutom dessa processer så anses numera mantelplymer haEarth history is punctuated by a series of events of supercontinent amalgamation and break-up. Fragments of old continents display rifted margins and orogenic sutures that testify their involvement in supercontinent cycles. Periods of break-up are associated with widespread magmatism due to extensional thinning and rifting of the lithosphere and in some instances the arrival of mantle plumes. Mant

A key question for evidence-based medicine (EBM) is how best to model the way in which EBM should‘[integrate] individual clinical expertise and the best external evidence’. We argue that the formulations and models available in the literature today are modest variations on a common theme and face very similar problems when it comes to risk analysis, which is here understood as a decision procedure

BACKGROUND: Dextran-70 is a more potent plasma volume expander than albumin but use has been hampered because of it's antithrombotic properties. However, also albumin has antithrombotic properties and little is known about relative effects of these two colloids on coagulation in-vivo when controlling for differences in efficacy as plasma volume expanders.AIM: Compare effects of dextran-70 and albu

Jordbruksmodernisering har dramatiskt ökat tillgången till mat på global nivå, men till ett högt pris för miljön. Idag efterlyser många ett ’paradigmskifte’ i jordbruket, även flera stora mainstream-institutioner. Med ett skifte till vad? Under senare år har det synts en ökande tilltro till agroekologi, ett alternativ som syftar till att förstå och bedriva jordbruk som komplexa agroekosystem. FrånAgricultural modernization has massively increased global food supply, but at a high environmental cost. Today many are calling for an agricultural ‘paradigm shift’, including several mainstream institutions. But to what? In recent years, agroecology has gained credence as an alternative approach that seeks to understand and manage farms as complex agroecosystems. From a development perspective, i
Cementproduktion står idag för en ansenlig andel av världens koldioxidutsläpp, vilket driver utvecklingen av bindemedel med lägre koldioxidutsläpp. För utsläppen i ett längre perspektiv är dock de nya bindemedlens beständighet absolut avgörande. De flesta nedbrytningsmekanismer är direkt relaterade till både fukt- och jontransport. Dessa processer har undersökts i många studier, men huvudsakligen Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. Most degradation of concrete structures is closely related to both moisture transport and ion transport. Many studi
I dag arbetar cirka 22 procent av de arbetande kvinnorna i Sverige i vård och omsorgssektorn. Vård och omsorg är en kvinnodominerad sektor som karaktäriseras av höga sjuktal, hög personalomsättning och rekryteringsproblem. Sveriges befolkning blir allt äldre samtidigt som vården av svårt sjuka patienter i allt högre grad flyttas ut från sjukhusen till hemmet. Detta utgör stora utmaningar för hemtj

As urban areas expand rapidly worldwide, wildlife is exposed to a wide range of novel environmental stressors, such as increased air pollution and artificial light at night. Birds in highly polluted and/or urbanized habitats have been found to have increased antioxidant protection, which is likely important to avoid accumulation of oxidative damage, which can have negative fitness consequences.
