Background: Although alcohol use disorder (AUD) is associated with future risk for psychosocial dysfunction, the degree to which this arises from a direct causal effect of AUD on functioning v. from correlated risk factors (also known as confounders) is less clearly established. Method: AUD was assessed from Swedish medical, criminal and pharmacy registries. In a large general population cohort, u

Objectives: Chronic pain is common in older adults, yet little is known of its development and the factors that predict its persistence and onset at old age. The aims of this longitudinal cohort study were to examine the prevalence and incidence of chronic pain and to explore possible risk factors for its persistence and onset in a representative sample of older Swedish adults. Method: Data were c

Asthma is associated with an increased risk of pulmonary embolism (PE) but little is known about whether asthma is associated with an increased risk of deep venous thrombosis (DVT). The aim in this study was to determine the risk of the first event of PE, DVT or a combination of PE and DVT in patients with asthma. We conducted this nationwide case-control study using data from Swedish nationwide r

Mitochondrial dysfunction may result in a variety of diseases. The objectives here were to examine possible differences in mtDNA copy number between healthy controls and patients with depression, anxiety or stress- and adjustment disorders; the association between mtDNA copy number and disease severity at baseline; and the association between mtDNA copy number and response after an 8-week treatmen

Objective: The purpose of this study was to clarify the magnitude and nature of the relationship between divorce and risk for alcohol use disorder (AUD). Method: In a population-based Swedish sample of married individuals (N=942,366), the authors examined the association between divorce or widowhood and risk for first registration for AUD. AUD was assessed usingmedical, criminal, and pharmacy regi

Epidermal growth factor (EGF) and inflammatory markers have been associated with various neuro-psychiatric disorders. However, their role in mild to moderate depression and anxiety patients treated with mindfulness-based group therapy (mindfulness) or cognitive behavioral therapy (CBT) is not known. In this study we analyzed plasma levels of interleukin (IL)-6, IL-8, high sensitivity C-reactive pr

Aims: To examine whether genetic influences on the development of alcohol use disorders (AUD) among men during emerging adulthood through mid-adulthood are stable or dynamic. Design: A twin study modeling developmental changes in the genetic and environmental influences on AUD during three age periods (18-25, 26-33 and 33-41) as a Cholesky decomposition. Setting: Sweden. Participants: Swedish male

Many B-cell neoplasms are associated with autoimmune diseases (AIDs) but most evidence is based on a personal rather than a family history of AIDs. Here we calculated risks for non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL) and multiple myeloma (MM) when family members were diagnosed with any of 44 different AIDs, or, independently, risk for AIDs when family members were diagnosed with a neopla

Background: Congestive heart failure (CHF) is a serious complication in patients with atrial fibrillation (AF). Objective: To study associations between relevant co-morbidities and CHF in patients with AF. Methods: Study population included all adults (n = 12,283) ≥45 years diagnosed with AF at 75 primary care centers in Sweden 2001-2007. Logistic regression was used to calculate odds ratios with

Familial risk of ovarian cancer is well-established but whether ovarian cancer clusters with other cancers and the clusters differ by histology remains uncertain. Using data from the Swedish Family-Cancer Database, we explored familial associations of ovarian cancer with other cancers with a novel approach; relative risk for (histology-specific) ovarian cancer was estimated in families with patien

Background: Although advances in the treatment of myeloid neoplasms have led to improved patient survival, this improvement has been accompanied by an increased risk of second primary cancer (ie, the risk of another cancer after myeloid neoplasia). We aimed to assess bi-directional associations between myeloid cancers and other cancers—ie, development of second primary cancer in patients who have

Purpose: The substantial literature showing that offspring of parents with alcohol use disorder (AUD) is at increased risk for externalizing psychopathology rarely examines the differential effects of parental and offspring sex. This literature also has other important limitations, such as modest sample sizes and use of unrepresentative samples. Using a large, nationwide Swedish sample, we aim to

Research SummaryGrowth often requires start‐ups to recruit new skills not present in the founding team. We analyze if the relationship between integrating new skills and growth depends on timing. Should new skills be recruited as early as possible, or can start‐ups add them as needed along the way? Using a unique panel dataset covering Sweden's population of start‐ups from 1997 to 2012, our analys

Background: Most literature on second primary cancers (SPCs) focuses on possible factors, which may increase the risk of these cancers, and little attention has been paid for the overall incidence differences between first primary cancers (FPCs) and same SPCs. We wanted to compare the incidence rates for all common cancers when these were diagnosed as FPCs and SPCs after invasive and in situ squam

Chronic kidney disease (CKD) is a multifactorial disorder with an important genetic component, and several studies have demonstrated potential associations with allelic variants. In addition, CKD patients are also characterized by high levels of genomic damage. Nevertheless, no studies have established relationships between DNA damage, or genomic instability present in CKD patients, and gene polym

Investigations of social-genetic effects, whereby a social partner’s genotype affects another’s outcomes, can be confounded by the influence of the social partner’s rearing environment. We used marital information on more than 300,000 couples from Swedish national data to disentangle social-genetic from rearing-environment effects for alcohol use disorder (AUD). Using observational and extended-fa

Aims: We tested the association between alcohol use disorder (AUD) and divorce; estimated the genetic and environmental influences on divorce; estimated how much genetic and environmental influences accounted for covariance between AUD and divorce; and estimated latent genetic and environmental correlations between AUD and divorce. We tested sex differences in these effects. Design: We identified

Rates of drug abuse are higher among divorced individuals than among those who are married, but it is not clear whether divorce itself is a risk factor for drug abuse or whether the observed association is confounded by other factors. We examined the association between divorce and onset of drug abuse in a population-based Swedish cohort born during 1965-1975 (n = 651,092) using Cox proportional h

Background: Although mindfulness-based group therapies (MGTs) for depressive, anxiety or stress and adjustment disorders are promising, there is a substantial lack of knowledge regarding the long-term improvements after such therapies in these common psychiatric disorders. Methods: Two hundred and fifteen patients were randomized in a randomized clinical trial (RCT) (ClinicalTrials.gov ID: NCT0147
