Background. Although the association between attention-deficit/hyperactivity disorder (ADHD) and drug use disorder (DUD) is well documented, it is unclear whether it is causal or results from familial confounding. Method. In this study we included all 551 164 individuals born in Sweden between 1991 and 1995 and used linked data from multiple nationwide registries to identify those with ADHD prior

HUmic-LIke Substances (HULIS) have been identified as major contributors to the organic carbon in atmospheric aerosol. The term "HULIS" is used to describe the organic material found in aerosol particles that resembles the humic organic material in rivers and sea water and in soils. In this study, two sets of filter samples from atmospheric aerosols were collected at different sites. One set of sa

Our objective was to examine the association between neighborhood linking social capital (a concept describing the amount of trust between individuals and societal institutions) and all-cause and cause-specific mortality in the elderly.

Objectives: To investigate associations between autoimmune disorders and Parkinson disease (PD), and to study whether the risk is associated with follow-up time and age. Methods: Standardized incidence ratios (SIRs) were calculated for PD in patients with autoimmune disorders by comparing them to subjects without autoimmune disorders. Results: Among 310,522 patients with a total of 33 conditions o

-Venous thromboembolism (VTE) clusters in families, but the familial risk of VTE has not been determined among adoptees. The aim was to disentangle the contributions of genetic and environmental factors to the familial transmission of VTE.

To examine, nationwide, if there is an association between country of birth in mothers and preterm birth and to study whether any such association remains in second-generation immigrant women. In this follow-up study, a nationwide research database located at Lund University, Sweden, was used to identify all preterm born singletons in Sweden between January 1, 1982, and December 31, 2006. Incidenc

Although antihypertensive drugs are known to reduce mortality in individuals with hypertension, the effects of different cardiovascular pharmacotherapies on mortality among patients with hypertension and atrial fibrillation (AF) have been less thoroughly explored. To study mortality rates in men and women separately with hypertension and AF prescribed different cardiovascular pharmacotherapies. A

Information can be provided by studying and evaluating past emergencies and the response in connection to them. This information would then be useful in efforts directed at preventing, mitigating and/or preparing for future emergencies. However, the analysis and evaluation of emergency response operations is not an easy task, especially when the operation involves several cooperating actors (e.g.

isk and vulnerability analysis (RVA) can benefit the process of preventing and preparing for disasters, both by generating a basis for making decisions and by enhancing risk awareness, safety culture and response capacity through the RVA process itself. In studying and understanding the practices related to RVA, insights can be gained regarding ways in which the RVA can be improved in society, as

This article analyses legal aspects of the Swedish wind power development, theoretically based on how different types of knowledge are represented in legal contexts, mainly in the courts. A sample of appealed wind power permits is analysed, a handful of relevant informants are interviewed – including two judges in the Land and Environment Court and the appeal court – and the legal setting is analy

Depression is associated with an increased risk for stroke. The aim of this study was to examine whether demographic and socioeconomic factors modify this association.

The aim of the present study was to examine demographic and socioeconomic differences and time trends of bariatric surgery in Sweden during 1990-2010.

We sought to clarify the etiological contribution of genetic and environmental factors to total criminal behavior (CB) measured as criminal convictions in men and women, and to violent (VCB), white-collar (WCCB) and property criminal behavior (PCB) in men only.

OBJECTIVES: Familial risk estimates are useful for genetic counseling, etiological understanding, and design of gene identification studies. We wanted to estimate the associations of ulcerative colitis (UC) and Crohn's disease (CD) with 32 autoimmune and related diseases among parents and offspring, singleton siblings, twins, and spouses. METHODS: The Multigeneration Register in Sweden provides re

The authors sought to clarify the relationship between IQ and subsequent risk for schizophrenia.

Preterm birth has been associated with increased risk of venous thromboembolism (VTE) in infancy, but the longer-term risk is unknown. Our aim was to examine this association from birth through young adulthood.

BACKGROUND: Cancer of unknown primary (CUP) is a fatal cancer for which incidence trends have changed but detailed survival trends remain unexplored. These could point out successful diagnostic and therapeutic approaches. We investigate survival trends in CUP according to histology, locations of metastases and site-specific causes of death. PATIENTS AND METHODS: A total of 20,523 CUP patients with

The importance of family history of venous thromboembolism (VTE) in cancer patients is unclear. We conducted a nationwide study to determine whether family history of VTE is a risk factor for hospitalized VTE in cancer patients.

Background High-dose aspirin (>= 500 mg daily) reduces long-term incidence of colorectal cancer, but adverse effects might limit its potential for long-term prevention. The long-term effectiveness of lower doses (75-300 mg daily) is unknown. We assessed the effects of aspirin on incidence and mortality due to colorectal cancer in relation to dose, duration of treatment, and site of tumour. Methods
