BACKGROUND: Identification of risk factors for rapid joint destruction in early rheumatoid arthritis (RA) can be helpful for optimizing treatment, and improving our understanding of destructive arthritis and its mechanisms. The objective of this study was to investigate the relationship between early RA patient characteristics and subsequent rapid radiographic progression (RRP).METHODS: An incepti

Background: The long-term effect of distal radial fracture malunion on activity limitations is unknown. Between 2001 and 2002, we conducted a prospective cohort study of all patients with distal radial fracture treated with casting or percutaneous fixation in northeast Scania in Sweden. In that original study, the patients completed the Disabilities of the Arm, Shoulder and Hand (DASH) questionnai

1. In a correlative study, we investigated the relative importance of fish predation, refuge availability and resource supply in determining the abundance and size distributions of the introduced and omnivorous signal crayfish (Pacifastacus leniusculus) in lakes and streams. Moreover, the biomass and food selection of predatory fish was estimated in each habitat type and stable isotopes of carbon

Context: After an anterior cruciate ligament (ACL) injury, a majority of patients have a traumatic bone marrow lesion (BML, or bone bruise). The clinical relevance of posttraumatic lesions remains unclear. Objective: To explore the cross-sectional associations between traumatic BML volume and self-reported knee pain and symptoms among individuals within 4 weeks of ACL injury. Design: Cross-section

Background: The aim of this study was to examine in elderly men a relationship between depressive symptoms, peripheral vascular disease and cerebral blood flow (CBF). Methods: Population-based cohort study started with an examination of 809 men at age 55, followed by the first (age 68ys) and second follow up (age 82ys). 128 survivors were examined at age 82 with Tc-99m-HMPAO-SPECT to estimate CBF,

Intermittent Parathyroid Hormone (PTH)((1-34)) has an established place in osteoporosis treatment, but also shows promising results in models of bone repair. Previous studies have been dominated by closed fracture models, where union is certain. One of the major clinical needs for anabolic therapies is the treatment of open and high energy fractures at risk of non-union. In the present study we th

Popular Abstract in Swedish Under det senaste decenniet har risker med och alternativ till allogent blod (blod från främmande givare) debatterats mycket pga. risken för smitta, allergiska reaktioner, samt starka indicier som talar för att blod från främmande givare kan påverka immunförsvaret hos mottagaren. Därför vill man gärna begränsa mängden tillfört givarblod under kirurgiska ingrepp på barn,In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23

Our aims were to characterize familial hypercholesterolemia (FH) in a Swedish FH population and to further elucidate the clinical expression and treatment response in relation to genotype. Secondly, we wanted to identify gene variants, which may have impact on cholesterol levels in apparently healthy subjects. In the search for sequence alterations in the large LDL receptor gene we introduced and

Background: Although omic-based discovery approaches can provide powerful tools for biomarker identification, several reservations have been raised regarding the clinical applicability of gene expression studies, such as their prohibitive cost. However, the limited availability of antibodies is a key barrier to the development of a lower cost alternative, namely a discrete collection of immunohist

The complement system, a part of the innate immune system with several links to the adaptive immune system, plays an important role in the pathogenesis of many diseases. The purpose of this thesis was to document and clarify some of these mechanisms. The thesis is based on four papers (I-IV). (I and II) Autoantibodies to the C3 cleaving enzyme complex of the alternative pathway, C3 nephritic facto

Objective: Transcatheter valve-in-valve implantation has emerged as an option, in addition to reoperative surgical aortic valve replacement, to treat failed biologic heart valve substitutes. However, the clinical experience with this approach is still limited. We report the comprehensive experience of transcatheter valve-in-valve implantation in the Nordic countries from May 2008 to January 2012.

Purpose: To assess the additional value of subtraction ictal single-photon emission computed tomography (SPECT) coregistered to MRI (SISCOM) for localization of the epileptogenic zone in patients with drug-resistant epilepsy scheduled for invasive video-EEG (VEEG) before epilepsy surgery by a descriptive study from clinical practice. Methods: Forty-nine consecutive epilepsy patients between Januar

Context: Secondary hypogonadism is common in aging men; its natural history and predisposing factors are unclear. Objectives: The objectives were 1) to identify factors that predispose eugonadal men (T >= 10.5 nmol/L) to develop biochemical secondary hypogonadism (T < 10.5 nmol/L; LH <= 9.4 U/L) and secondary hypogonadal men to recover to eugonadism; and 2) to characterize clinical features associ

BACKGROUND: Hemostatic disorders are common in obstetric complications. Thromboelastography (TEG (R)) simultaneously measures coagulation and fibrinolysis within 10 to 20 minutes. Our primary aim in this prospective longitudinal study was to obtain knowledge about physiological changes in TEG (R) variables during normal pregnancy and 8 weeks postpartum. The secondary aims were to compare TEG (R) v

Background: Podocalyxin-like 1 (PODXL) is a cell-adhesion glycoprotein and stem cell marker that has been associated with an aggressive tumour phenotype and adverse outcome in several cancer types. We recently demonstrated that overexpression of PODXL is an independent factor of poor prognosis in colorectal cancer (CRC). The aim of this study was to validate these results in two additional indepen

The Baltic Sea is one of many aquatic ecosystems that show long-term declines in dissolved silicate (DSi) concentrations due to anthropogenic alteration of the biogeochemical Si cycle. Reductions in DSi in aquatic ecosystems have been coupled to hydrological regulation reducing inputs, but also with eutrophication, although the relative significance of both processes remains unknown for the observ

The aim of this thesis was to elucidate developments in epidemiology, clinical manifestations and complications in Chlamydia trachomatis (C.trachomatis) and Mycoplasma genitalium (M.genitalium) infection. In study I the frequencies of non-gonococcal salpingitis, gonococcal salpingitis and ectopic pregnancy (EP) were observed over a period of 28 years and correlated to the prevalence of Neisseria g

We have investigated the effects of the novel imidazoline compound (+)-2-(2-(4,5-dihydro-1H-imidazol-2-yl)-thiopene-2-yl-ethyl)pyridine (NNC77-0074) on stimulus-secretion coupling in isolated pancreatic alpha- and beta-cells. NNC77-0074 stimulated glucose-dependent insulin secretion in intact mouse pancreatic islets. No effect was observed at less than or equal to 2.5 mM glucose and maximal stimul

Background: End-stage kidney disease overwhelms health services in Central America. We determined prevalences of decreased kidney function in distinct populations in the most affected region of Nicaragua. Study Design: Cross-sectional survey. Setting & Participants: Total populations aged 20-60 years of 5 villages in Northwest Nicaragua: mining/subsistence farming (elevation, 100-300 m above s
