In the beginning of the COVID-19 pandemic, several super spreader events occurred during singing in choirs, which lead to an increased attention to airborne transmission of SARS-CoV-2, the virus causing COVID-19. Since then, aerosol generation from singing has been studied in more detail, however, only from healthy subjects. In this study, we collected aerosol particles in the exhaled breath of 40
Background: Little is known regarding treatment with cangrelor during percutaneous coronary intervention (PCI) in patients with myocardial infarction complicated by cardiogenic shock or cardiac arrest. Objectives: The aim of this study was to investigate the effects of such cangrelor treatment during PCI in patients with myocardial infarction complicated by cardiogenic shock or cardiac arrest. Met
The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). This bias may influence the derived outputs, such as soil temperature, permafrost ext
Objectives To describe the endosonographic image of the anal sphincter 2-7 days after delivery in women who had undergone a primary repair of an obstetric sphincter tear. Methods Forty-eight women who had suffered a third- or fourth-degree sphincter tear at delivery and had undergone primary sphincter repair were examined with endoanal sonography 2-7 days after delivery. A score from 0 to 16 was
Leptin is a key biological marker related to energy balance and development of diabetes and cardiovascular diseases. Its levels are increased in populations with a high degree of the metabolic syndrome. Life history of evolution has, however, largely taken place under the ecological context of hunting and gathering. In this study, we explored whether the first steps of transition to sedentary agri
Bird migration was recorded by tracking radar and visual observation at 23 sites in the region of the Northwest Passage, between Baffin Island and Herschel Island in the Beaufort Sea. The studies took place during a ship-based expedition from 29 June to 3 September 1999. A total of 692 tracks (average duration 160 s) of bird flocks on postbreeding migration were recorded. Eastward migration was wi
OBJECTIVE: To identify perinatal factors associated with cerebral palsy (CP). METHODS: This was a case-control study based on the Swedish Medical Birth Registry and the Swedish Hospital Discharge Registry, including 2,303 infants born in Sweden 1984-1998 with a diagnosis of CP and 1.6 million infants without this diagnosis. Odds ratios (ORs) with 95% confidence intervals (Cis) were calculated. RES
BACKGROUND AND PURPOSE: To determine how a recently proposed clinical stroke subclassification corresponds to specific findings on computed tomography (CT) and magnetic resonance imaging (MRI) of the brain. METHODS: Two hundred twenty-eight patients with first-ever stroke were divided into four clinical subgroups: (1) total anterior circulation syndrome: both cortical and subcortical symptoms from
Popular Abstract in Swedish Variabilitet i ett läkemedels farmakokinetiska (hur ett läkemedel omsätts i kroppen) och farmakodynamiska (vilken effekt ett läkemedel har) egenskaper kan resultera i att olika individer som erhållit samma dos av ett läkemedel får olika effekter av läkemedel. Biverkningar eller utebliven effekt kan innebära allvarliga konsekvenser för den enskilda individen. VariabiliteVariability in pharmacokinetic and pharmacodynamic parameters between individuals can be due to intrinsic and extrinsic factors. In this thesis three different areas regarding sources of variability have been investigated. 1. Formulation properties as an extrinsic source of variability. Lipophilic substances often have poor oral bioavailability and high inter- and intraindividual variability. High
Popular summary The fate of non-steroidal anti-inflammatory drugs The knowledge about distribution of drugs between sewage sludge, water phases and water living organisms is vital for predictions of the fate and transport routes of toxic substances to the environment. And the distribution of drugs in the environment can be used as a base for risk assessments and it also can be used to define desir
Purpose: Off-target binding in the skull and meninges is observed in some subjects undergoing tau positron emission tomography (PET) and could potentially differ between men and women. In this study we elucidate sex differences in tau off-target binding using three different tau PET tracers. Methods: 541 cognitively unimpaired amyloid-β negative participants underwent tau PET using [18F]flortaucip
Background: Gun violence is a global health problem. Population-based research on firearm-related injuries has been relatively limited considering the burden of disease. The aim of this study was to analyze nationwide epidemiological trends of firearm injuries. Methods: This is a retrospective nationwide epidemiological study including all patients with firearm injuries from the Swedish Trauma Reg
BACKGROUND/PURPOSE: There is a lack of large contemporary studies on the management of congenital diaphragmatic hernia (CDH), and the prediction of mortality remains difficult. The aim of this study was to investigate the influence of perinatal factors on mortality rate in a contemporary multicenter study. METHODS: The authors conducted a retrospective multicenter cohort study. Twelve of 13 Scandi
OBJECTIVES: Inhibitors of the glucagon-like peptide-1 (GLP-1)-degrading enzyme, dipeptidyl peptidase IV (DPPIV), are being explored in the treatment of diabetes. We examined the long-term influence of a selective, orally active inhibitor of DPPIV (NVP DPP728), in normal female C57BL/6J mice and such mice rendered glucose-intolerant and insulin-resistant by feeding a high-fat diet. DESIGN: In mice
Laminitis and energy-related postpartum diseases share several risk factors, indicating a common etiology. Thus, a herd's incidence rate of energy-related postpartum diseases, such as displaced abomasum and clinical ketosis, might reflect the likelihood of cows to suffer from laminitis-related claw lesions. The aim of this study was to investigate the association between herd-level incidence rate
To evaluate the long term effect on lower extremity function and working capacity after stenting of iliocaval vein segments for acute deep venous thrombosis (DVT) or chronic venous occlusive disease. During a 14 year period from November 1994 to October 2008, 114 patients with median age 36 (interquartile range [IQR], 27-48) years, 72 (63%) women, 72 (63%) with hypercoagulable disorders, with acut
This thesis describes attempts at estimating the uncertainty of the 2-metre temperature forecast error from a probabilistic point of view, utilizing Bayesian neural networks. Bayesian neural networks are a type of machine-learning algorithms used to find patterns in data and make probabilistic predictions. Multiple fields of output data from the ECMWF IFS global model, along with temperature measu
In the summer of 2021 a massive rainfall caused floods in Gävleborg län. The flood contributed to high burden on SOS-alarm and the fire and rescue service when approximately 700 emergency calls were received in a short amount of time. The flood caused floodings in cellars, damage to infrastructure and problems moving through traffic. The high burden caused the inner commanding officer of the fire
Overheating in buildings is becoming a major concern and cause for various health issues. Existing research and previous studies on the issue were examined to acquire relevant information about the definition of overheating, its possible causes, and the heath impacts it could have on human health. The review included data on the current status of thermal comfort and overheating regulations in Swed
