Socioeconomic status (SES) and its association with cancer in general have been thoroughly studied in the last decades. Several studies have shown associations between SES and many types of cancer such as lung cancer, breast cancer, and prostate cancer. For gliomas, no clear occupational or exposure risk factors have been identified, although some possible risk factors such as use of cellular telephone are still controversial. The aim in the present study is to analyze whether there is an association between SES and development of brain cancer...

PURPOSE: Quality registers give unique possibilities to achieve information from large groups of patients, but outcome must be interpreted carefully due to less stringent data collection and lower follow-up rates than in research projects. We tried to quantify any outcome differences between a national spine quality register and a prospective observational study. METHODS: Adult patients treated with lumbar discectomy between 2004 and 2010 were retrieved from the Swedish Spine register (Swespine) (n = 7791) and from the single center lumbar disc herniation study (LDHS) in Stockholm (n = 177)...

BACKGROUND: Over the past decades, reorganizations and structural changes in Swedish primary care have affected time utilization among health care professionals. Consequently, increases in administrative tasks have substantially reduced the time available for face-to-face consultations. This study examined how work-time was utilized and the association between work time utilization and the perceived psychosocial work environment in Swedish primary care settings. METHODS: This descriptive, multicentre, cross-sectional study was performed in 2014-2015...

BACKGROUND: Takotsubo cardiomyopathy (TCM), also known as "broken heart syndrome", is a type of heart failure characterized by transient ventricular dysfunction in the absence of obstructive coronary lesions. Although associated with increased levels of catecholamines, pathophysiological mechanisms are unknown. Relapses and family heritability indicate a genetic predisposition. Several small studies have investigated associations between three different loci; the β1-adrenic receptor (ADRB1), G-protein-coupled receptor kinase 5 (GRK5), Bcl-associated athanogene 3 (BAG3) and TCM but no consensus has been reached...

BACKGROUND: The 2014 ILAE clinical definition of epilepsy allows diagnosis after a single unprovoked seizure if the 10-year recurrence risk exceeds 60%. Multiple sclerosis (MS) carries an increased risk of epilepsy, but the risk after a first seizure is unknown. We aimed to investigate the risk of epilepsy in patients with MS who had suffered a first seizure. METHODS: We cross-referenced data from the Swedish MS-register with the national patient register for 15810 MS patients and 43635 controls and included 289 MS patients and 222 controls with a first diagnosis of seizure or status epilepticus (SE) without prior epilepsy or presumed symptomatic aetiology...

Background and purpose - Several studies have reported on the influence of various factors on patient-reported outcomes (PROs) after total hip arthroplasty (THA), but very few have focused on the experience of the surgeon. We investigated any association between surgeons' experience and PROs 1 year after primary THA. Patients and methods - Patient characteristics and surgical data at 10 hospitals in western Sweden were linked with PROs (EQ-5D-3L, Satisfaction Visual Analogue Scale (VAS), Pain VAS). These data were retrieved from the Swedish Hip Arthroplasty Register (SHAR)...

AIMS: Diuretics are recommended for treating congestive symptoms in heart failure (HF). The short- and long-term prognostic effects of diuretic treatment at hospital discharge have not been studied in randomized clinical trials or in a Western world population. We aimed to determine the association of diuretic treatment at discharge with the risk of short-and long-term all-cause mortality in real-life patients in Sweden with HF irrespective of EF. METHODS AND RESULTS: From a Swedish nationwide HF register 26,218 patients discharged from hospital were included in the present study...

BACKGROUND: Self-harm is common in youth and an important risk factor for suicide. Certain self-harm methods might indicate a higher risk of suicide. The main aim of this study was to determine whether some methods of self-harm in adolescents (10-17 years) and young adults (18-24 years) are associated with a particularly high risk of suicide. A secondary aim was to ascertain how different self-harm methods might affect the probability of psychiatric follow-up. METHOD: Five Swedish registers were linked in a national population-based cohort study...
