Objective: Levothyroxine treatment is common among older adults as is atrial fibrillation (AF), yet less is known about its potential effects on the development of dementia. Methods: The study population included all adults with diagnosed AF (n = 156,104) aged ≥ 45 years in Sweden without an earlier recorded diagnosis of dementia. Individuals with a dispensed prescription of levothyroxine on two o

Importance: Preterm birth has previously been associated with increased risks of hypertension and diabetes, but not ischemic heart disease (IHD), in adulthood. The reasons for this lack of association with IHD despite associations with its risk factors have been elusive, but may be associated with methodologic issues, such as survivor bias, in prior studies. Objective: To determine whether preterm

Viral infections predispose to the development of childhood asthma, a disease associated with increased lung mast cells (MCs). This study investigated whether viral lower respiratory tract infections (LRTIs) can already evoke a MC response during childhood. Lung tissue from young children who died following LRTIs were processed for immunohistochemical identification of MCs. Children who died from

Classroom acoustics not always take the speaker's comfort into consideration. The purpose of the presented papers was to investigate voice use, vocal behavior and prevalence of voice problems in Swedish teaching staff. Ratings of features in the work-environment on voice use were explored in n = 487 teachers. Based on their answers the respondents were split into two groups: teachers with self-ass

Background: No study to date, as far as we know, has analyzed the potential effect of neighborhood-level deprivation on autoimmune disorders (ADs), when adjusted for individual-level characteristics. Methods: A total of 5.4 million individuals from 8363 neighborhoods, comprising the whole Swedish population (ages 25-74 years), were followed for the period 1 January 2000, until admission due to dia

Background: The risk of dementia is increased in patients with atrial fibrillation (AF). Objective: To study relevant co-morbidities and incident dementia (vascular dementia, Alzheimers disease, other dementia and all dementia) in AF patients. Methods: All adults (n = 537,513) ≥45 years diagnosed with AF in hospitals in Sweden 1998–2012 were included. Cox regression was used to estimate hazard rat

Aims: Abdominal aortic aneurysm is a life-threatening condition due to the risk of aneurysm growth and rupture. There are no approved diagnostic or prognostic biomarkers for abdominal aortic aneurysm. We aimed to identify diagnostic and prognostic biomarkers for abdominal aortic aneurysm and to investigate their relationship with abdominal aortic aneurysm diameter and growth. Methods: In this case

OBJECTIVES: Alcohol use disorders (AUD) is well known to aggregate in families and is associated with socioeconomic status (SES). The objective was to study the effect of education, income and neighborhood SES in adulthood on AUD, and to explore whether the potential associations were confounded by shared familial factors, by using a co-relative control design. METHODS: Data on AUD was drawn from

Background: Patients with atrial fibrillation (AF) have an increased dementia risk dementia. We aimed to study the effect of antihypertensive drugs on dementia in AF patients. Methods: Included patients were ≥45 years diagnosed with AF in Swedish National Patient Register (n = 160,251; 89,723 men and 70,528 women) and alive on January 1, 2007. We excluded patients with dementia before onset of AF.

Artificial groundwater recharge is commonly used for drinking water supply. The resulting water quality is highly dependent on the raw water quality. In many cases, pre-treatment is required. Pre-treatment improves the drinking water quality, although how and to what extent it affects the subsequent pond water quality and infiltration process, is still unknown. We evaluated two treatment systems b

AimsCan drug abuse (DA) be transmitted psychologically between adult siblings consistent with a social contagion model?MethodsWe followed Swedish sibling pairs born in 1932-1990 until one of them, sibling1 (S1), had a first DA registration. We then examined, using Cox regression, the hazard rate for a first registration for DA in sibling2 (S2) within 3 years of a first DA registration in S1 as a f

Leaders of today need to achieve well in terms of task performance, perceiving low stress, and having high levels of work engagement. One may ask whether trait-based leadership resource factors can be identified and how such resource factors might relate to task performance, perceived stress, and work engagement. Our aim was to test the hypothesis, derived from Hobfoll’s motivational Conservation

Background: Peripheral nerve injuries cause substantial problems when not treated properly. A specific problem is reconstruction of nerve defects, which can be treated in different ways. This study aimed to systematically review whether processed nerve allograft (PNA) is justified in reconstruction of a nerve defect in patients after posttraumatic or iatrogenic peripheral nerve injury and to compa

BackgroundThis study explores expectations for telepresence robots as a tool to reduce absence in education as school absence negatively influences children's academic advancement and psychosocial wellbeing.DesignA qualitative semi-structured interview study.Method and populationUsing convenience sampling, we interviewed 11 children aged 8–17 years with cancer (n = 4), neuromuscular diseases (n =

BACKGROUND: Foreign-born workers in high-income countries experience higher rates of COVID-19 but the causes are only partially known.AIMS: To examine if the occupational risk of COVID-19 in foreign-born workers deviates from the risk in native-born employees in Denmark.METHODS: Within a registry-based cohort of all residents employed in Denmark (n = 2 451 542), we identified four-digit DISCO-08 o

Chimney sweeps have higher incidence and mortality of cardiovascular disease (CVD), likely related to their exposure to polycyclic aromatic hydrocarbons (PAH). In order to identify underlying mechanisms of PAH-related CVD, we here investigated whether PAH exposure was associated with levels of putative CVD-related proteins in serum among currently working chimney sweeps. We enrolled 116 chimney sw

Manganese (Mn), an essential nutrient, is a neurotoxicant at high concentrations. We measured Mn concentrations in repeated blood and hair samples collected from 449 pregnant women living near banana plantations with extensive aerial spraying of Mn-containing fungicide mancozeb in Costa Rica, and examined environmental and lifestyle factors associated with these biomarkers. Mean blood Mn and geome

Are there research methods and methodologies that are inherently queer or transfeminist in empirical research? This is a question I wrestle with often. And I am not alone, although methodological discussions are less central in queer and transfeminist knowledge production than in the wider feminist field. Transfeminist discussions of methodology often set our from a research ethics starting point;
