Breath-hold ECG-gated cardiovascular magnetic resonance (CMR) imaging is challenging during exercise due to motion, ECG-problems, and lengthy scans. To facilitate time-resolved volumetric measures from exercise-CMR, we aimed to develop a method for constructing time-resolved ventricular cines from real-time free-breathing exercise-CMR. Time-resolved ventricular cines were semi-automatically constr

Background: A Swedish version of the Patient-Rated Ulnar Nerve Evaluation (PRUNE-S), a patient-reported outcome measure for ulnar nerve entrapment, was created, according to cross-cultural adaptation guidelines, and reliability, validity, and responsiveness were evaluated. Methods: In total, 43 patients (mean [SD] age, 49 [16] y; 54% men) were consecutively examined, including the PRUNE-S (retest:

OBJECTIVE: To estimate the prevalence and predictors of sustained remission (SR) in patients with psoriatic arthritis (PsA) receiving biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in Sweden. METHODS: All patients with PsA initiating b/tsDMARDs and who were registered in the national Swedish Rheumatology Quality Register (SRQ) from April 1999 to December 2019 wer

Background: The impact of surgical specialization on long-term survival in patients undergoing emergent colon cancer resections remains unclear. Method: A retrospective analysis was conducted on all patients who underwent emergent colon cancer resections at a secondary care hospital between 2010 and 2020. The most senior surgeon performing the procedures was classified as colorectal surgeon (CS) o

Climate warming is expected to influence the prevalence of vector-transmitted parasites. Understanding the extent to which this is ongoing, or has already occurred, requires empirical data from populations monitored over long periods of time, but these studies are sparse. Further, vector-disease research involving human health is often influenced by disease control efforts that supersede natural t

Methanol can be produced renewably and used in compression ignition (CI) engines as a replacement for fossil diesel. However, methanol is a low cetane fuel, creating challenges in achieving stable operation, particularly at low load. One potential solution is through surface ignition via a glow plug. In this work, experiments were conducted on a methanol-fueled 2.1 L single cylinder engine instrum

Objective: To evaluate the causal effect of genetically predicted serum urate (SU) levels on the risk of overall and major site-specific cancers in individuals of European ancestry, using Mendelian randomization (MR) analysis. Method: Data from two population-based cohorts from southern Sweden, the Malmö Diet and Cancer Study (MDCS) and Malmö Preventive Project (MPP), and summary-statistics data f

We investigated integrative physiological responses to eupnoeic exercise (EX), rebreathing exercise (RB), dynamic apnoea (DA) and dynamic apnoea with cold-water face immersion (DAFI) in 20 healthy participants. Trials involved non-steady-state cycle exercise at 60 W for an average duration of 66 s. With increases in heart rate and stroke volume, EX and RB increased cardiac output compared with bas

Observational studies suggest that direct contact from healthcare to at-risk relatives may increase genetic counselling (GC) uptake as compared to family-mediated risk disclosure, but randomised controlled trials (RCTs) are lacking. This study assessed whether the offer of direct letters to relatives at risk of hereditary breast and ovarian cancer (HBOC) or Lynch syndrome increases GC uptake compa

Background and aimMany patients with depressive disorders do not improve with first-line treatment with selective serotonin inhibitors (SSRIs). Adverse drug reactions (ADRs) are common. However, there are no reliable methods to predict treatment response.The general aim of this thesis was to investigate the role of peripheral serotonin and the polymorphic CYP2D6 gene as potential biomarkers of tre

Introduction: Suturing is a fundamental component of surgical procedures, wherein training emphasises the significance of gentle tissue handling. The suturing process involves the pressure exerted by the forceps onto the tissue, as well as the medial traction force applied to stabilise the tissue during the needle bite. This study examined the forces involved in tissue handling during suturing, co

Background: Alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) are frequently comorbid and are individually associated with increased risk of suicidal behavior. However, whether their comorbidity exacerbates this risk has not been adequately investigated. Methods: Using a Swedish birth cohort (born 1970–1990; N = 799,203–858,983), we employed Aalen’s linear hazards models to evalu

Background: Programmed death-ligand 1 (PD-L1) immunocytochemical (ICC) analysis of cell blocks (CBs) has recently emerged in clinical practice. Unlike standardized immunohistochemistry on formalin-fixed, paraffin-embedded tissues, cytology involves various preparation methods and fixatives. This study investigated how various fixatives influence PD-L1 immunoreactivity in CBs from malignant pleural

GOALS: To assess the incidence, type, and severity of infections in patients with IBD before and after starting thiopurine therapy.BACKGROUND: Thiopurines have been used for decades in the treatment of inflammatory bowel disease (IBD), yet real-world data regarding the extent and types of infections associated with their use are scarce.STUDY: We included all thiopurine-naive adults with IBD who in

Background: We aimed to assess the risk of serious infections in patients with inflammatory bowel disease (IBD) exposed to different advanced therapies. Methods: We linked nationwide registers and compared rates of incident serious infections in patients with Crohn’s disease (CD) and ulcerative colitis (UC) exposed to medical therapies versus matched general population comparators during 2007-2023

Introduction: Using time-limited trials of low-dose, sustained-release morphine to reduce chronic breathlessness to evaluate net effects may generate opioid withdrawal symptoms if medication is ceased. This sub-study of a larger randomized, placebo-controlled, double-blind trial aimed to evaluate if this occurred. Methods: People with modified Medical Research Council breathlessness scores of 3 or

Accurate, high-resolution global land use and land cover (LULC) mapping is crucial for environmental monitoring, but remains challenging when relying solely on multispectral data. Most existing global LULC mapping studies rely exclusively on multispectral observations, and even those that incorporate synthetic aperture radar (SAR) data often fail to fully exploit the information it provides. SAR p

Introduction Systemic inflammation is postulated to mediate heat stroke and heat-related organ injury, yet acute inflammatory responses among heat-stressed workers remains poorly understood. We aimed to describe neutrophil mobilisation and potential release of DNA during heat stress in multiple hot occupational settings and a controlled experimental setting. Methods Neutrophil:lymphocyte ratio (NL

Aims: Sorbitol and myo-inositol levels and morphology of sural nerve were compared with nerve function and clinical neuropathy in men with diabetic, impaired (IGT), and normal glucose tolerance. Methods: After neurography of sural nerve and determinations of sensory thresholds for vibration, warm and cold on the foot, whole nerve sural nerve biopsy was performed in 10 men with Type 1 diabetes mell

1. In the present study, the vasodilator actions of methanandamide and capsaicin in the rat isolated mesenteric arterial bed and small mesenteric arterial segments were investigated. 2. Methanandamide elicited concentration-dependent relaxations of preconstricted mesenteric arterial beds (pEC 50 = 6.0 ± 0.1, E(max) = 87 ± 3%) and arterial segments (pEC 50 = 6.4 ± 0.1, E(max) = 93 ± 3%). 3.
