The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. The tracking is done at the radar by operating the transmitter at one frequency and the receiver at twice the frequenc
Introduction: The main purpose of this study was to extract global values of oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen (CMRO2) in healthy volunteers, using magnetic resonance imaging (MRI) phase maps. The repeatability of the method was evaluated, and the age dependences of OEF and CMRO2 were analyzed. Material and methods: Phase data were acquired using a 3T MRI scann
Background: The rapid increase in type 2 diabetes worldwide has mainly been attributed to lifestyle factors, including poor eating habits and physical inactivity. Type and quality of diet is a key factor in both prevention and treatment of type 2 diabetes. Aim: To investigate the association between diet quality and risk of type 2 diabetes. Methods and Subjects: This prospective study in the M
PurposeAntimicrobial resistance increases with the use of broad-spectrum antibiotics. Studies evaluating antibiotic stewardship are in high demand. Is piperacillin/tazobactam non-inferior to carbapenems regarding 30-day mortality among patients with bloodstream infections caused by extended-spectrum beta-lactamase-producing Enterobacterales?MethodsThis retrospective, multicenter, non-inferiority,
BACKGROUND: Previous post hoc analyses of clinical trials have suggested that a higher percentage of systolic blood pressure time in target range (SBP-TTR) was associated with a decreased risk of cardiovascular disease (CVD). However, there is limited evidence from large prospective cohort studies on the relationship between long-term SBP-TTR and the risk of CVD.OBJECTIVES: The purpose of this stu
An outpouring of scholarly editions: Media history perspectives on the editing of historical sources in Sweden, 1834–1847This article examines the scholarly editing of historical sources for publication in nineteenth-century Sweden. The analysis focuses on the approximately 500 letters exchanged between Hans Järta, the Director General of the National Archives of Sweden, and Bror Emil Hildebrand,
INTRODUCTION: Low birth weight is an important measure of the health of pregnant women and newborns. We investigated the prevalence of low birth weights in India over nearly three decades to assess trends and convergence across states.METHODS: Data came from five waves of the National Family Health Survey (1992-93 to 2019-21). The prevalence of low birth weight was estimated. To explore the sensit
Background: There are currently no molecular tests to identify individual breast cancers where radiotherapy (RT) offers no benefit. Profile for the Omission of Local Adjuvant Radiotherapy (POLAR) is a 16-gene molecular signature developed to identify low-risk cancers where RT will not further reduce recurrence rates. Methods: An individual participant data meta-analysis was performed in 623 patien
BACKGROUND: Despite the significant personal and societal burden of tic disorders (TDs), treatment outcomes remain modest, necessitating a deeper understanding of their etiology. Family history is the biggest known risk factor, and identifying risk genes could accelerate progress in the field.METHODS: Expanding upon previous sample size limitations, we added 4800 new TD cases and 971,560 controls
BACKGROUND: The first 35 years of pediatric heart transplantation (pHTx) in Sweden were investigated to determine outcomes following listing and transplantation, investigate sub-populations of recipients, and describe the presence of donor-specific antibodies (DSA) in a contemporary cohort.METHODS: Swedish children < 18 years, listed from 1/1/1989 to 31/12/2023, were included. The cohort was split
Background: Racial differences in metastatic castration-resistant prostate cancer (mCRPC) genomes have not yet been fully studied. We aimed to investigate transcriptomic, mutational, and clinical differences by race in a large multi-institutional cohort of men with mCRPC. Methods: Genomic and clinicopathologic data from four mCRPC tumor biopsy cohorts were obtained and aggregated. Gene set enrichm
BACKGROUND AND AIMS: Adhering to the EAT-Lancet diet has been observed to be associated with lower risks of various morbidities. This study aimed to investigate the association of adhering to the EAT-Lancet diet with incident chronic obstructive pulmonary disease (COPD) and identify plasma proteins mediating such association.METHODS: This prospective study involved 202 340 participants free of COP
Aims: To examine the separate associations of glycemic control and chronic kidney disease with hospitalization days over one year in patients with type 2 diabetes (T2D). Materials and methods: A cross-sectional study using retrospective data on T2D patients in Region Halland, Sweden, during 2020. Data from the Region Halland database included hospitalizations, emergency visits, primary care encoun
Aims: Drug–gene interactions (DGIs) modify drug response and safety, yet their influence on diabetic microvascular complications remains unclear. This study aimed to elucidate the role of DGIs in these complications. Materials and Methods: Using UK Biobank (UKB) data, we identified medications frequently prescribed to individuals with diabetes and defined DGIs based on the Food and Drug Administra
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
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
