The blood loss-reducing effect of desmopressin during dextran therapy was studied in a double-blind fashion in 79 elderly but otherwise healthy patients with preoperative normal bleeding time undergoing total hip replacement for primary coxarthrosis. An infusion of desmopressin (0.3 microgram/kg body weight) or placebo was randomly administered immediately after administration of spinal anaesthesi
Breathlessness is a major cause of suffering and distress and little is known about the trajectory of breathlessness near death.
Aim: The present investigation was designed to evaluate the health-related quality of life (HRQOL) of adolescents with asthma between the age of 16 and 21, when they are transferred from paediatric to adult care. Methods: In this prospective study, 156 teenagers (69 females) with asthma were screened employing spirometry, a histamine challenge, skin prick test for allergy and filled out the 'Liv
OBJECTIVE: Children who undergo surgery for complex congenital cardiac disease are reported to be at increased thrombotic risk. Our aim was to evaluate long-term changes in the haemostatic system after surgery, to compare markers of activated coagulation in children having surgery with those in a healthy control population, and to relate them to adverse clinical outcome.Patients and methodsWe stud
BACKGROUND: Shortening of the atrial refractory period is the key feature of atrial electrical remodeling during atrial fibrillation (AF). During sinus rhythm (SR), assessment of the atrial refractoriness is hampered by the fact that the atrial repolarization wave (Ta wave) is largely obscured by the following QRST complex. The purpose of this study was to study the Ta wave in subjects with paroxy
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
Fibroblasts are dynamic structural cells that direct both beneficial tissue repair and pathological organ fibrosis through interactions with tissue-resident type 2 lymphocytes (T2Ls) and type 3/17 lymphocytes (T3Ls). The cytokines interleukin-13 (IL-13) and IL-17A, produced by T2Ls and T3Ls, respectively, are linked to both tissue inflammation and fibrosis, but how their spatial positioning influe
We investigated dynamic changes in nicotinamide adenine dinucleotide (NAD+) metabolism in the human occipital lobe using ultra-high field 31P functional magnetic resonance spectroscopy (fMRS) at 7 T. Twenty-five healthy volunteers (mean age 24 ± 4 years, 10 females) performed a visual task alternating between fixation and flashing checkerboard stimuli. 31P MRS spectra were acquired from a visual c
The focus of this thesis is on cerebellar-dependent sensorimotor tasks during development. The performance in classical delay eyeblink conditioning, prism adaptation, and isochronous serial interval production (finger tapping) was explored in typically developing school-aged children, young adolescents, and adults. These three tasks share that the cerebellum plays a critical role when it comes to
Objective: To explore the relative importance of risk factors, treatments, and blood counts for the occurrence of vascular complications and their impact on life expectancy in essential thrombocythemia (ET) and polycythemia vera (PV). Methods: Nested case-control study within the Swedish MPN registry. From a cohort of 922 ET patients and 763 PV patients, 71 ET and 81 PV cases with vascular complic
Context: Little is known about the individual response of glucose-regulating factors to administration of exogenous insulin infusion in extremely preterm infants. Objective: To evaluate longitudinal serum concentrations of insulin, C-peptide, and plasma glucose levels in a high-frequency sampling regimen in extremely preterm infants treated with insulin because of hyperglycemia. Design: Prospectiv
The long-term ecological interactions between fire and the composition of dominant trees and shrubs in boreal and cold temperate Fennoscandian forests are still under discussion. We hypothesized that fire-prone taxa should abound during periods and regions characterized by higher fire disturbance, while fire-intolerant taxa should dominate when and where fire activity is low. Biomass burning (BB)
The Covid-19 pandemic significantly influenced public discourse, particularly on the use of face masks, with social media serving as a platform for the public to express their opinions and share experiences. This study examines how the Swedish public supports their arguments when discussing their stance on face masks during the Covid-19 pandemic, split into three categories: (1) personal opinions,
Extensive ringing data from a coastal site (Falsterbo Bird Observatory) in southwesternmost Sweden were used to investigate the occurrence of reverse autumn migration among 20 passerine bird species oF widely different migration categories. The data demonstrate that reverse migration is a widespread and regular phenomenon among nocturnal as well as diurnal migrants and among irruptive migrants, te
Positron emission tomography (PET) may provide important information on the therapeutic response of radiopharmaceutical therapy (RPT) during therapy. The radiation emission from the RPT radionuclide may disturb the coincidence detection and impair the image resolution. In this study we tested the feasibility to perform intratherapeutic PET on three preclinical PET systems.METHODS: Using (22)Na poi
Understanding the role of the medial temporal lobe (MTL) in learning and memory is an important problem in cognitive neuroscience. Memory and learning processes that depend on the function of the MTL and related diencephalic structures (e.g., the anterior and mediodorsal thalamic nuclei) are defined as declarative. We have studied the MTL activity as indicated by regional cerebral blood flow with
Treatment with pancreatic or pancreatic-like microbial enzymes during the suckling period has positive effects on the gut, resulting in a better fat absorption and improved barrier function in pigs. The present study investigated the effects of pancreaticlike enzyme treatment during the pre- or postweaning period on pig growth and nitrogen utilization. Suckling 7- to 14-d-old pigs were gavage fed
