PCDD/Fs and dl-PCBs, or more commonly referred to as dioxin and dioxin like substances are compounds present in our surrounding environment. As some congeners of these have been shown to be toxic, they are regulated under the Stockholm Convention. As dioxins are persistent in biota and have lipophilic properties they are seen accumulating in lipid rich fish in the Baltic, one of the affected speci

Popular Abstract in Swedish Patienter med diabetes mellitus har högt blodsocker. Insulin reglerar blodsockervärdena. Redan i slutet av 1800 talet föreslogs att skulle det finnas två olika typer av diabetes, den ena beroende på bristande insulinbildning, den andra beroende på bristande insulineffekt. I början av 1900 talet utvecklades insulinframställningen. Observationer av blodsockernivåerna i blThe Diabetes Incidence Study in Sweden (DISS) registers diabetes in young adults aged 15-34 years in Sweden. This thesis aims to validate the ascertainment, methods in the classification of diabetes, and putative etiological factors such as family background, psychological stress, and BMI, that may affect the incidence of diabetes in young adults, in the DISS registry. The capture-recapture method

Popular Abstract in Swedish Denna avhandling behandlar design, tillverkning, karakterisering och optimering av elektroniska komponenter alla baserade på kvantmekanisk tunnling. Tunnling är ett rent kvantmekaniskt fenomen utan någon klassisk motsvarighet, som först blir relevant då dimensionerna krymper ner i nanometerskala (en nanometer är en miljarddel's meter). Då kan elektroner ”tunnla” igenomThis thesis concerns different kinds of tunneling based devices all showing negative differential resistance. The thesis is divided in three parts, resonant tunneling transistors, Esaki diodes and coupled zero dimensional systems. The resonant tunneling transistors are GaAs-based vertical field effects transistors, based on a combination of overgrown tungsten gates and double barrier heterostruct

Background The extent to which adult height, a biomarker of the interplay of genetic endowment and early-life experiences, is related to risk of chronic diseases in adulthood is uncertain. Methods We calculated hazard ratios (HRs) for height, assessed in increments of 6.5 cm, using individual-participant data on 174 374 deaths or major non-fatal vascular outcomes recorded among 1 085 949 people in

Context:TSH-secreting pituitary adenomas (TSHomas) are rare. Epidemiological data are scant and there are no reports on national incidence.Objective:The objective of the study was to estimate the national Swedish incidence and prevalence of TSHomas.Design:This was an observational study.Setting:The study was conducted at tertiary referral centers.Patients:The Swedish Pituitary Registry and World H

Background We investigated whether prediagnostic reported intake of dairy products and dietary calcium are associated with colorectal cancer (CRC) survival. Methods Data from 3,859 subjects with CRC (42.1% male, mean age at diagnosis 64.2 ± 8.1 years) in the European Investigation into Cancer and Nutrition (EPIC) cohort were analyzed. Intake of dairy products and dietary calcium was assessed at ba

PURPOSE: To compare progressive dynamic, relative quantitative changes in glycans associated with retinal proteins of wild type (wt) and retinal degeneration 1 (rd1) mice during neonatal development and degeneration of retinae. METHODS: Proteins extracted from retinae of postnatal day 2 (PN2), PN7, PN14 wt and rd1 mice were labeled with Cy3-fluorescent dye. Glycome of these proteins was quantified

Introduction: The potential association between hypo-and hyperthyroid disorders and breast cancer has been investigated in a large number of studies during the last decades without conclusive results. This prospective cohort study investigated prediagnostic levels of thyrotropin (TSH) and triiodothyronine (T3) in relation to breast cancer incidence in pre- and postmenopausal women. Methods: In the

Objective. To investigate whether rates of cartilage loss differ in knees with frequent baseline pain versus those without pain, after adjustment for radiographic osteoarthritis (OA) stage. Methods. One knee in each of 718 Osteoarthritis Initiative participants was examined: 310 with calculated Kellgren/Lawrence (K/L) grade 2, 299 with calculated K/L grade 3, and 109 with calculated K/L grade 4. T

Objective A pay-for-performance (P4P) programme for primary care was introduced in 2011 by a Swedish county (with 1.6 million inhabitants). Effects on register entry practice and comparability of data for patients with diabetes mellitus were assessed. Design and setting Observational study analysing short-term outcomes before and after introduction of a P4P programme in the study county as compare

Background: The effects on left and right ventricular (LV, RV) volumes during physical exercise remains controversial. Furthermore, no previous study has investigated the effects of exercise on longitudinal contribution to stroke volume (SV) and the outer volume variation of the heart. The aim of this study was to determine if LV, RV and total heart volumes (THV) as well as cardiac pumping mechani

Purpose: To assess and correlate the levels of inflammatory mediators in the eyes from non-diabetic and diabetic subjects without retinopathy (NDR), with non-proliferative diabetic retinopathy (NPDR) or with proliferative diabetic retinopathy (PDR) to corresponding erum levels. Methods: The levels of interleukin 1β, interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were analysed by an EL

Quadrivalent human papillomavirus (HPV) vaccine has been shown to provide protection from HPV 6/11/16/18-related cervical, vaginal, and vulvar disease through 3 years. We provide an update on the efficacy of the quadrivalent HPV vaccine against high-grade cervical, vaginal, and vulvar lesions based on end-of-study data from three clinical trials. Additionally, we stratify vaccine efficacy by sever

Drought is a climate risk that affects access to safe water, crop development, ecological stability, and food production. Therefore, developing drought prediction methods can lead to better management of surface and groundwater resources. Similarly, machine learning can be used to find improved relationships between nonlinear variables in complex systems. Initially, the standardized precipitation

BACKGROUND: The efficacy of corticosteroids for treating acute vestibular neuritis, or acute unilateral vestibulopathy (AUVP), remains controversial.OBJECTIVE: This study aimed to evaluate whether corticosteroids improve vestibular function and reduce symptoms in both acute and chronic phases of AUVP.METHODS: This randomized, placebo-controlled, double-blind trial included patients with AUVP (ages

Familial Platelet Disorder with associated Myeloid Malignancy (FPDMM, FPD/AML, RUNX1-FPD), caused by monoallelic deleterious germline RUNX1 variants, is characterized by bleeding diathesis and predisposition for hematologic malignancies, particularly myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Clinical data on FPDMM-associated AML (FPDMM-AML) are limited, complicating evidence

Background and Objectives: Temporomandibular disorders (TMDs) is an umbrella term for pain and dysfunction involving jaw muscles and/or the temporomandibular joint, with whiplash trauma suggested to be one risk factor. The aim was to evaluate prevalence and relative risk of TMDs in the acute and chronic stages after whiplash trauma. Databases and Data Treatment: This review was registered in Prosp

Purpose: Myocardial infarctions (MIs) can occur in underlying obstructive coronary artery disease (MI-CAD) or in non-obstructive coronary arteries (MINOCA). The primary objectives of the study were to investigate the prevalence of MI-CAD and MINOCA in people with CAL, and to explore if CAL is an independent risk factor for MI-CAD and MINOCA. Secondary objectives were to explore these research ques

BACKGROUND: Previous studies of glucagon stimulation test (GST) in children have shown variable results regarding the utility and reliability of the cortisol response to this test and its correlation with clinical parameters. The aim of this study was to assess cortisol levels at GST and to evaluate how clinical parameters, such as age, sex, pubertal status and Body Mass Index (BMI), correlate to

ObjectiveSputum cultures can guide antibiotic therapy, particularly in severe pneumonia or when resistant pathogens are suspected. However, data on how prior and ongoing antibiotic exposure affects microbial detection are limited. This study aimed to evaluate this impact, stratified by timing and route of administration.MethodsIn- and outpatients from nine hospitals in Skåne, Sweden, who submitted
