OBJECTIVE: To examine whether vagotomy decreases the risk of Parkinson disease (PD). METHODS: Using data from nationwide Swedish registers, we conducted a matched-cohort study of 9,430 vagotomized patients (3,445 truncal and 5,978 selective) identified between 1970 and 2010 and 377,200 reference individuals from the general population individually matched to vagotomized patients by sex and year of birth with a 40:1 ratio. Participants were followed up from the date of vagotomy until PD diagnosis, death, emigration out of Sweden, or December 31, 2010, whichever occurred first...

Background: Traditional obesity prevention programs are time- and cost-intensive. Mobile phone technology has been successful in changing behaviors and managing weight; however, to our knowledge, its potential in young children has yet to be examined.Objective: We assessed the effectiveness of a mobile health (mHealth) obesity prevention program on body fat, dietary habits, and physical activity in healthy Swedish children aged 4.5 y.Design: From 2014 to 2015, 315 children were randomly assigned to an intervention or control group...

AIMS: To explore whether older women differ from younger women with respect to sick leave and inpatient care at the time around their first pregnancy and delivery. METHODS: This was a descriptive population-based cohort study.

We examined the trajectories of work disability before and after IHD and stroke events. New IHD (n = 13521) and stroke (n = 7162) cases in 2006-2008 were retrieved from nationwide Swedish hospital records and their annual work disability days five years before and after the date of diagnosis were retrieved from a nationwide disability register. There was no pre-event differences in disability days between the IHD and stroke cases and five years prior to the event, they were close to those observed in the general population...

Importance: The death of a close relative is associated with an increased mortality risk among the bereaved, but much less is known about the potential association of the death of a sibling in childhood with mortality in this population. Objective: To examine the association between sibling death in childhood and subsequent mortality risk. Design, Setting, and Participants: This population-based cohort study of 5 005 029 participants evaluated linked national registers in Denmark (January 1, 1973, through December 31, 2009) and Sweden (January 1, 1973, through December 31, 2008)...

OBJECTIVE: The aim of this study was to examine mortality causes and cancer incidence in a population cohort that have resided in close proximity to highly metal-contaminated sources, characterized by contamination of, in particular, arsenic (As), cadmium (Cd), and lead (Pb). METHODS: Data from Swedish registers were used to calculate standardized mortality and cancer incidence ratios. An attempt to relate cancer incidence to metal contamination levels was made...

OBJECTIVE: Transitions in the spectrum of valvular heart diseases (VHDs) in developed countries over the 20th century have been reported from clinical case series, but large, contemporary population-based studies are lacking. METHODS: We used nationwide registers to identify all patients with a first diagnosis of VHD at Swedish hospitals between 2003 and 2010. Age-stratified and sex-stratified incidence of each VHD and adjusted comorbidity profiles were assessed...

BACKGROUND: Gastrointestinal cancers are characterized by a male predominance, suggesting a role of sex hormones.We hypothesized that digitalis medication, due to its estrogenic properties, decreases the risk of male-predominated gastrointestinal cancers. RESULTS: Long -term digitalis use (≥2 years) was followed by decreased risk for several gastrointestinal cancers, but associations were statistically significant only for liver cancer (hazard ratio [HR]=0.40, 95% confidence interval (CI) 0...

Background: Over half of breast cancer patients discontinue their adjuvant hormone therapy, permanently or temporarily. We aimed to identify predictors of treatment restarting after discontinuation of adjuvant hormone therapy and to test the hypothesis that treatment restarting is associated with better breast cancer outcomes.

BACKGROUND: Moral Case Deliberation is one form of clinical ethics support described as a facilitator-led collective moral reasoning by healthcare professionals on a concrete moral question connected to their practice. Evaluation research is needed, but, as human interaction is difficult to standardise, there is a need to capture the content beyond moral reasoning. This allows for a better understanding of Moral Case Deliberation, which may contribute to further development of valid outcome criteria and stimulate the normative discussion of what Moral Case Deliberation should contain...

BACKGROUND: Prognostic factors in patients with localised primary cutaneous malignant melanoma (CMM) are well described. However, prognostic factors for recurrence are less documented. OBJECTIVES: The aim of this study was to identify prognostic risk factors for first recurrence in patients with localised stage I-II CMM using population-based data.

BACKGROUND: Individuals with type 1 diabetes mellitus (T1DM) have a high risk of cardiovascular complications, but it is unknown to what extent fulfilling all cardiovascular treatment goals is associated with residual risk of mortality and cardiovascular outcomes in those with T1DM compared with the general population. METHODS: We included all patients ≥18 years of age with T1DM who were registered in the Swedish National Diabetes Register from January 1, 1998, through December 31, 2014, a total of 33 333 patients, each matched for age and sex with 5 controls without diabetes mellitus randomly selected from the population...

BACKGROUND: Our objective was to assess the impact of obstetric mode of delivery, and in particular birth by Caesarean section (CS), on school performance in adolescents using a large, population-based cohort. METHODS: We extracted data from the Swedish Medical Birth Register and National School Register. We included all live singleton births in Sweden from 1982-1995 (n = 1,489,925). School grades were reported on a scale from 0 to 320, scores less than 160 (i...
