BACKGROUND: Pregnancies resulting through oocyte donation have been associated with increased risk for adverse outcomes for the mother, such as gestational hypertensive disorders. However, little is known about possible neonatal complications of such pregnancies. The purpose of this study was to evaluate the neonatal health outcomes among singleton pregnancies in a population of relatively young and healthy oocyte recipients in Sweden, taking into account the medical indication leading to treatment...

AIMS/HYPOTHESIS: The aim of this study was to identify risk factors associated with confirmed fatal hyperglycaemia, which could predispose potentially preventable deaths in individuals on glucose lowering drugs. METHODS: A retrospective register-based case-control study conducted on a nationwide cohort with individuals who died due to hyperglycaemia as determined by forensic postmortem examination, in Sweden August 2006 to December 2012. Vitreous glucose was used to diagnose hyperglycaemia postmortem...

BACKGROUND: The detection of celiac disease (CD) is suboptimal. AIMS: We hypothesized that misdiagnosis is leading to diagnostic delays, and examine this assertion by determining if patients have increased risk of abdominal surgery before CD diagnosis. METHODS: Through biopsy reports from Sweden's 28 pathology departments we identified all individuals with CD (Marsh stage 3; n=29,096). Using hospital-based data on inpatient and outpatient surgery recorded in the Swedish Patient Register, we compared abdominal surgery (appendectomy, laparotomy, biliary tract surgery, and uterine surgery) with that in 144,522 controls matched for age, sex, county and calendar year...

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 = 773925) born in 1954-1970 with no history of previous VTE were followed from enlistment (1972-1990) until 2010. Data on cardiovascular fitness using a cycle ergonometric test (maximal aerobic workload in Watt [Wmax]) at conscription were linked with national hospital register data and the Multi-Generation Register...

OBJECTIVE: To investigate the safety and efficacy of rituximab in multiple sclerosis (MS). METHODS: In this retrospective uncontrolled observational multicenter study, off-label rituximab-treated patients with MS were identified through the Swedish MS register. Outcome data were collected from the MS register and medical charts. Adverse events (AEs) grades 2-5 according to the Common Terminology Criteria for Adverse Events were recorded. RESULTS: A total of 822 rituximab-treated patients with MS were identified: 557 relapsing-remitting MS (RRMS), 198 secondary progressive MS (SPMS), and 67 primary progressive MS (PPMS)...

Family history of cancer is a well-known risk factor but the role of family history in survival is less clear. The aim of this study was to investigate the association between family history and cancer survival for the common cancers in Sweden. Using the Swedish population-based registers, patients diagnosed with the most common cancers were followed for cancer-specific death during 1991-2010. We used multivariate proportional hazards (Cox) regression models to contrast the survival of patients with a family history of cancer (individuals whose parent or sibling had a concordant cancer) to the survival of patients without a family history...

BACKGROUND AND AIMS: Both high and low fasting glucose has been associated with an increased mortality among individuals without diabetes. This J-shaped association has also been shown for HbA1c in relation to all-cause mortality. High fructosamine is associated with increased mortality. In this study we aim to evaluate if low fructosamine is also associated with increased mortality in non-diabetic subjects. METHODS AND RESULTS: We included 215,011 subjects from the AMORIS cohort undergoing occupational health screening or primary care in Stockholm, Sweden...

BACKGROUND: The injury spectrum published in the literature has mainly been presented for a certain age group, as elderly or for a certain type of injury, as fracture and often restricted to in-hospital care cases. Our objective was to give an overview of the major types of injuries for all age groups and trends in the adult population. METHODS: We analyzed 68,159 adult injury events, which occurred between 1999 and 2008 and was treated at the Emergency Department of Umea University Hospital...

CONTEXT: Screening of autoimmune thyroid disease in children and young adults with Type 1 diabetes is important but vary greatly between clinics. OBJECTIVE: The aim was to determine the predictive value of thyroid autoantibodies, thyroid function, islet autoantibodies, and HLA- DQ at diagnosis of Type 1 diabetes for autoimmune thyroid disease during subsequent follow-up. SETTING: 43 Paediatric Endocrinology units Sweden. Design, patients and main outcome measures: At diagnosis of Type 1 diabetes, samples from 2433 children were analysed for autoantibodies against thyroid peroxidase (TPOAb), thyroglobulin (TGAb), glutamic acid decarboxylase (GADA), insulin (IAA), insulinoma-associated protein-2 (IA-2A), and the three variants of the zinc transporter 8 (ZnT8W/R/QA) as well as HLA-DQA1-B1 genotypes and thyroid function...

BACKGROUND: The inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC) have been associated with an increased risk of preterm birth. MATERIAL AND METHODS: We identified all 246 singleton preterm births among women with IBD between July 2006 and December 2010 as cases and an equal number of controls with IBD from the Swedish national health registers, matched by maternal age, parity and IBD diagnosis (CD/UC). From register data and medical charts, we obtained information on reproductive history, comorbidity, disease activity and drug treatment (corticosteroids, 5-aminosalicylates, sulfasalazine, thiopurines and anti-TNF) as risk factors for preterm birth...

BACKGROUND AND PURPOSE: Guidelines recommend that carotid endarterectomy should be performed within 2 weeks in patients with a symptomatic carotid stenosis. Because a Swedish register study indicated that patients treated within the first days after a stroke or transient ischemic attack might have an increased perioperative stroke and mortality risk, this study aimed to find out whether these findings are also true under everyday conditions in Germany. METHODS: Secondary data analysis including 56 336 elective carotid endarterectomy procedures performed for symptomatic carotid stenosis under everyday conditions between 2009 and 2014...

Despite limited and ambiguous empirical data, substance use-related problems have been assumed to be rare among patients with autism spectrum disorders (ASD). Using Swedish population-based registers we identified 26,986 individuals diagnosed with ASD during 1973-2009, and their 96,557 non-ASD relatives. ASD, without diagnosed comorbidity of attention deficit hyperactivity disorder (ADHD) or intellectual disability, was related to a doubled risk of substance use-related problems. The risk of substance use-related problems was the highest among individuals with ASD and ADHD...

BACKGROUND: Prior studies suggest parental and perinatal risk factors are associated with later offending. It remains uncertain, however, if such risk factors are similarly related to sexual offending. METHOD: We linked socio-demographic, family relations, and perinatal (obtained at birth) data from the nationwide Swedish registers from 1973 to 2009 with information on criminal convictions of cases and control subjects. Male sex offenders (n = 13 773) were matched 1:5 on birth year and county of birth in Sweden to male controls without sexual or non-sexual violent convictions...

BACKGROUND: Adjuvant chemotherapy for stage II and III rectal cancer patients is a matter of discussion. The aim of the present study was to evaluate the prognostic value of lymphovascular (LVI) and perineural (PNI) invasion in stage II rectal cancer on a national level. MATERIALS AND METHODS: Clinico-pathological factors associated with disease-free survival (DFS) and time to recurrence in stage II rectal cancer patients were analyzed from patient data registered in the Swedish Colorectal Cancer Registry between 2006 and 2012...

Background: Total hip arthroplasty (THA) is one of the most common and successful surgical procedures in orthopedic surgery and clinical success can be characterized by the revision rate and improvement of function, as well as the patient's satisfaction and pain. Despite the clinical success of primary THA with 10-year survival rates as high as 96 % (Swedish Hip Arthroplasty Register, 2011), the prevalence of groin pain after conventional total hip replacement ranges from 0.4 to 18.3 % and activity-limiting thigh pain is still an existing problem linked to the femoral component of uncemented hip replacement in up to 1...

BACKGROUND: Bereavement is thought to be a risk factor for suicide but the association has not been thoroughly investigated according to specific sensitive time periods and risk groups using a self-matched design. We aimed to 1) determine the risk of suicide within the first year after death of a close relative, 2) investigate if and how the risk changes within this time window and 3) determine if sex, age, and type of relationship, affect this association. METHODS: A self-matched, case-crossover study was performed by linking Swedish registers...
