The relationship between the genetic and environmental risk factors for alcohol use disorders (AUD) detected in Swedish medical, pharmacy, and criminal registries has not been hitherto examined. Prior twin studies have varied with regard to the detection of shared environmental effects and sex differences in the etiology of AUD. In this report, structural equation modeling in OpenMx was applied to
Background: The epidemiology of metastatic gastric cancer is unexplored because cancer registries seldom cover metastatic involvement apart from "present or not". We used a novel approach by utilizing Swedish registers to assess metastatic spread in gastric cancer. To our knowledge, this is the first nationwide description of metastases in gastric cancer. Results: The most common sites of metastas
Using Swedish nationwide registry data, the authors investigated the correlation of genetic and environmental risk factors in the etiology of drug abuse as ascertained from medical and criminal registries by modeling twin and sibling data. Medical drug abuse was defined using public inpatient and outpatient records, while criminal drug abuse was ascertained through legal records. Twin, full and ha
Objective To study the risk of myocardial infarction (MI) in patients with atrial fibrillation (AF) treated in primary health care with warfarin or acetylsalicylic acid (ASA, aspirin). Methods The study population included subjects (n = 12,283) 45 years or older diagnosed with AF who were treated in 75 primary care centres in Sweden between 2001 and 2007. MI was defined as a hospital stay for MI d
Background: Criminal offending is strongly transmitted across generations. Aims: To clarify the contribution of rearing environment to crossgenerational transmission of crime. Method: Using Swedish national registries, we identified 1176 fullsibling and 3085 half-sibling sets from high-risk families where at least one sibling was adopted and the other raised by the biological parents. Results: Ris
Objective: The authors sought to clarify the relationship between marriage and risk for alcohol use disorder. Method: The association between marital status and risk for first registration for alcohol use disorder in medical, criminal, and pharmacy registries was assessed in a population-based Swedish cohort (N=3,220,628) using longitudinal timedependent survival and co-relative designs. Results:
The epidemiology of metastases in neuroendocrine tumors (NETs) is virtually unknown. The present novel approach took use of two nationwide Swedish registers to assess the distribution of metastatic sites in comparison to adenocarcinoma. 7,334 patients with NET were identified from the Swedish Cancer Registry. Metastatic sites were identified from the National Patient and Cause of Death Registries.
Studies on whether family history (FH) of venous thromboembolism (VTE) affects long-term mortality after VTE are missing. The aim of this study was to determine whether FH of VTE affects long-term mortality after a first episode of VTE. Using Swedish medical databases, we conducted a 30-year nationwide cohort study of 49,159 adult Swedish born patients included in the multi-generation register (bo
Background: Whether high cardiovascular fitness is associated with reduced risk of venous thromboembolism (VTE) is unknown. The present study aims to determine whether high cardiovascular fitness reduces the risk of VTE. Methods: A Swedish cohort of male conscripts (n = 773,925) born in 1954–1970 with no history of previous VTE were followed from enlistment (1972–1990) until 2010. Data on cardiova
Well developed emergency response capabilities are crucial in order to keep the risk in a community at low levels. Analysing these capabilities before an emergency occurs is important since it can identify weaknesses and possibilities for improvements. To start off from an operational definition is a possible point of departure in such an analysis. In this paper, therefore, we develop an operation
Preparedness planning is part of the disaster management process in many countries and it includes building capabilities to improve the effectiveness of response to various scenarios. Sweden, the Netherlands and the United Kingdom all use risk and vulnerability analyses together with capability assessments as part of their preparations for disasters. Whereas the definitions of risk and vulnerabili
In this paper an approach for employing risk and vulnerability analyses as the basis for emergency preparedness planning is discussed and exemplified using a case study. The study consisted of three connected parts: a broad scope hazard identification and analysis, an assessment of potential assistance needs should any of the hazards materialise and finally a mapping of actors and dependencies. Th
BACKGROUND: High body mass index (BMI) and low physical fitness are risk factors for stroke, but their interactive effects are unknown. Elucidation of interactions between these modifiable risk factors can help inform preventive interventions in susceptible subgroups.METHODS: National cohort study of all 1,547,294 military conscripts in Sweden during 1969-1997 (97-98% of all 18-year-old males). St
Background: Alcohol Use Disorder (AUD) is clinically heterogeneous. Using a large epidemiological sample ascertained via public registries, is it possible to identify clinical and historical features of AUD that reflect familial risk? Methods: Using registration in national medical, legal or pharmacy registries, we identified four kinds of relative pairs (n = 683,223) starting with a proband with
Objective: Familial risks of glomerulonephritis (acute, chronic and unspecified glomerulonephritis) have not been studied. This study aims to determine the familial risks of glomerulonephritis. Methods: Individuals born from1932 onwards diagnosed with glomerulonephritis (acute [n = 7011], chronic [n = 10,242] and unspecified glomerulonephritis [n = 5762]) were included. The familial risk (Standard
BACKGROUND: It is widely believed that autoimmune diseases affect predominantly in women, but the available evidence came from case control study with potential selection and recall bias. We aimed to examine the gender-specific incidence of autoimmune diseases by using national wide registers in Sweden.METHODS: Swedish Hospital Discharge Register and Outpatient Register were used to identify a set
BACKGROUND: Twin studies have been criticized for upwardly biased estimates that might contribute to the missing heritability problem.METHOD: We identified, from the general Swedish population born 1960-1990, informative sibships containing a proband, one reared-together full- or half-sibling and a full-, step- or half-sibling with varying degrees of childhood cohabitation with the proband. Estima
OBJECTIVE: This nationwide study aimed to determine whether venous thromboembolism (VTE) shares familial susceptibility with aortic aneurysm (AA), peripheral artery disease (PAD) and arterial thrombosis and embolisation (ATE) in locations other than the heart and brain.METHODS: Nationwide Swedish family study. Data from the Swedish Multi-Generation Register for subjects aged 0-78 years old, coveri
