Association Between Intellectual Functioning and Autistic Traits in the General Population of Children.

Autistic traits are continuously distributed in the general population. The associations between autistic traits and intellectual functioning and/or behavioural difficulties, and the impact of intellectual functioning on behavioural difficulties are unclear. The study aims to describe the distribution of autistic traits in a population-based cross-sectional sample of children. Further aims are to examine the association between intellectual functioning and autistic traits, and between autistic traits and behavioural difficulties. Wechsler scales and ratings of autistic traits and behavioural problems in 874 children aged 7-9 years in the Swedish Environmental Longitudinal Mother and Child, Asthma and Allergy (SELMA) study were assessed. We found a continuous distribution of autistic traits. Intellectual functioning was negatively associated with autistic traits but not with behavioural difficulties. Behavioural difficulties were associated with autistic traits.

Self-assessed preoperative level of habitual physical activity predicted postoperative complications after colorectal cancer surgery: A prospective observational cohort study.

INTRODUCTION: There is a growing interest in physical activity in relation to recovery after surgery. One important aspect of measuring recovery after surgical procedures is postoperative complications. The aim of this study was to determine if there is an association between the preoperative level of habitual physical activity and postoperative complications in patients undergoing elective surgery for colorectal cancer. MATERIALS AND METHODS: 115 patients scheduled for elective surgery due to colorectal cancer between February 2014 and September 2015 answered a questionnaire regarding physical activity and other baseline variables. Physical activity was assessed using the Saltin-Grimby physical activity level scale. Complications within 30 days after surgery were classified according to Clavien-Dindo, and the Comprehensive Complications Index (CCI) was calculated. Primary outcome was difference in CCI and key secondary outcome was risk for CCI ≥20. RESULTS: Physically inactive individuals had a CCI that was 12 points higher than individuals with light activity (p = 0.002) and 17 points higher than regularly active individuals (p = 0.0004). Inactive individuals had a relative risk for a CCI ≥20 that was 65% higher than for individuals reporting light activity (95% confidence interval (CI) for relative risk (RR) = 1.1-2.5) and 338% higher than for regularly active individuals (95% CI for RR = 2.1-9.4). CONCLUSION: Self-assessed level of habitual physical activity before colorectal cancer surgery was associated with fewer postoperative complications measured with CCI, in a dose-response relationship.

Clinical effectiveness of care managers in collaborative care for patients with depression in Swedish primary health care: a pragmatic cluster randomized controlled trial.

BACKGROUND: Depression is one of the leading causes of disability and affects 10-15% of the population. The majority of people with depressive symptoms seek care and are treated in primary care. Evidence internationally for high quality care supports collaborative care with a care manager. Our aim was to study clinical effectiveness of a care manager intervention in management of primary care patients with depression in Sweden. METHODS: In a pragmatic cluster randomized controlled trial 23 primary care centers (PCCs), urban and rural, included patients aged ≥ 18 years with a new (< 1 month) depression diagnosis. Intervention consisted of Care management including continuous contact between care manager and patient, a structured management plan, and behavioral activation, altogether around 6-7 contacts over 12 weeks. Control condition was care as usual (CAU). OUTCOME MEASURES: Depression symptoms (measured by Mongomery-Asberg depression score-self (MADRS-S) and BDI-II), quality of life (QoL) (EQ-5D), return to work and sick leave, service satisfaction, and antidepressant medication. Data were analyzed with the intention-to-treat principle. RESULTS: One hundred ninety two patients with depression at PCCs with care managers were allocated to the intervention group, and 184 patients at control PCCs were allocated to the control group. Mean depression score measured by MADRS-S was 2.17 lower in the intervention vs. the control group (95% CI [0.56; 3.79], p = 0.009) at 3 months and 2.27 lower (95% CI [0.59; 3.95], p = 0.008) at 6 months; corresponding BDI-II scores were 1.96 lower (95% CI [- 0.19; 4.11], p = 0.07) in the intervention vs. control group at 6 months. Remission was significantly higher in the intervention group at 6 months (61% vs. 47%, p = 0.006). QoL showed a steeper increase in the intervention group at 3 months (p = 0.01). During the first 3 months, return to work was significantly higher in the intervention vs. the control group. Patients in the intervention group were more consistently on antidepressant medication than patients in the control group. CONCLUSIONS: Care managers for depression treatment have positive effects on depression course, return to work, remission frequency, antidepressant frequency, and quality of life compared to usual care and is valued by the patients.

Is the quality of primary healthcare services influenced by the healthcare centre's type of ownership?-An observational study of patient perceived quality, prescription rates and follow-up routines in privately and publicly owned primary care centres.

BACKGROUND: Primary healthcare in Sweden has undergone comprehensive reforms, including freedom of choice regarding provider, freedom of establishment and increased privatisation aiming to meet demands for quality and availability. In this system privately and publicly owned primary care centres with different business models (for-profit vs non-profit) coexist and compete for patients, which makes it important to study whether or not the type of ownership influences the quality of the primary healthcare services. METHODS: In this retrospective observational study (April 2011 to January 2014) the patient perceived quality, the use of antibiotics and benzodiazepine derivatives, and the follow-up routines of certain chronic diseases were analysed for all primary care centres in Region Västra Götaland. The outcome measures were compared on a group level between privately owned (n = 86) and publicly owned (n = 114) primary care centres (PCC). RESULTS: In comparison with the group of publicly owned PCCs, the group of privately owned PCCs were characterized by: a smaller, but continuously growing share of the population served (from 32 to 36%); smaller PCC population sizes (avg. 5932 vs. 9432 individuals); a higher fraction of PCCs located in urban areas (57% vs 35%); a higher fraction of listed citizens in working age (62% vs. 56%) and belonging to the second most affluent socioeconomic quintile (26% vs. 14%); higher perceived patient quality (82.4 vs. 79.6 points); higher use of antibiotics (6.0 vs. 5.1 prescriptions per 100 individuals in a quarter); lower use of benzodiazepines (DDD per 100 patients/month) for 20-74 year olds (278 vs. 306) and >74 year olds (1744 vs.1791); lower rates for follow-ups of chronic diseases (71.2% vs 74.6%). While antibiotic use decreased, the use of benzodiazepines increased for both groups over time. CONCLUSIONS: The findings of this study cannot unambiguously answer the question of whether or not the quality is influenced by the healthcare centre's type of ownership. It can be questioned whether the reform created conditions that encouraged quality improvements. Tendencies of an (unintended) unequal distribution of the population between the two groups with disparities in age, socio-economy and geography might lead to unpredictable effects. Further studies are necessary for evidence-informed policy-making.

Comparative effectiveness of budesonide-formoterol combination and fluticasone-salmeterol combination for asthma management: a United States retrospective database analysis.

BACKGROUND: Comparative effectiveness of the budesonide-formoterol fumarate dihydrate combination (BFC) and the fluticasone propionate-salmeterol combination (FSC) therapy on asthma exacerbation has not been assessed in real-world settings in the United States. OBJECTIVE: To compare exacerbation rates and health care utilization for patients with asthma who initiate BFC versus FSC therapy. METHODS: This retrospective cohort comparative effectiveness study queried medical and pharmacy data for patients with asthma from a large managed care data repository that covers major US population centers. The patients were 12 to 64 years old, with ≥12 months of pre- and postindex enrollment and ≥1 pharmacy claim(s) for BFC or FSC initiated during June 1, 2007, and September 30, 2010; the first prescription fill date was defined as the index date. Patients with other respiratory diseases and/or cancer were excluded. Exacerbation was defined as asthma-related hospitalization, emergency department visit, and/or oral corticosteroid prescription fill. Cohorts were matched by using propensity scores. RESULTS: A total of 3043 patients per cohort were matched and balanced. During the 12 months following the initiation the BFC cohort had lower adjusted exacerbations per person year versus the FSC cohort (0.85 vs 0.93; RR 0.92, 95% CI [0.85-0.99]), lower oral corticosteroid fill rates, and fewer asthma-related emergency department visits but comparable asthma-related hospitalization. CONCLUSIONS: Asthma exacerbation was lower for BFC versus FSC initiators due to lower rates of oral corticosteroid use and asthma-related emergency department visits, which indicate better treatment effectiveness of those patients initiated with BFC compared with FSC.

A US database study characterizing patients initiating a budesonide-formoterol combination versus tiotropium bromide as initial maintenance therapy for chronic obstructive pulmonary disease.

OBJECTIVE: To compare clinical and demographic characteristics, resource utilization and costs of chronic obstructive pulmonary disease (COPD) patients prior to initiating budesonide-formoterol combination (BFC) or tiotropium-maintenance therapy. MATERIALS AND METHODS: This cross-sectional study used claims-based diagnosis to identify COPD patients in the HealthCore Integrated Research Database who initiated BFC or tiotropium therapy between March 1, 2009 and January 31, 2012 (intake period); the index date was defined as the initial prescription fill for either agent. Patients diagnosed with respiratory tract cancer or receiving inhaled corticosteroids/long-acting ß2-adrenergic agonists or tiotropium in 12 months prior to index date were excluded. Categorical variables were evaluated with χ(2) tests; mean cost differences were evaluated using γ-regression. RESULTS: Overall, 6,940 BFC and 10,831 tiotropium patients were identified. The BFC group was younger (mean age 64 versus 67 years), with a greater proportion of females (54% versus 51%). BFC-treated patients had more comorbid respiratory conditions, including asthma (25% versus 13%), but fewer comorbid cardiovascular conditions, including atherosclerosis (7% versus 10%) and myocardial infarction (4% versus 6%). A greater proportion of BFC patients received prior respiratory medication, including oral corticosteroids (46% versus 35%) and short-acting ß2-agonists (44% versus 35%). Tiotropium-treated patients had a greater mean number of COPD-related outpatient visits (4.6 versus 4.1). BFC-treated patients had lower total all-cause ($17,259 versus $17,926) and COPD-related ($1,718 versus $1,930) health care costs, driven by lower all-cause and COPD-related inpatient expenditures. CONCLUSION: Initiators of BFC or tiotropium showed differences in clinical and demographic characteristics and health care utilization and costs prior to starting COPD maintenance therapy.

Long-term follow-up after radical cystectomy with emphasis on complications and reoperations: a Swedish population-based survey.

OBJECTIVE: To evaluate outcome after radical cystectomy for primary bladder cancer in a large population-based material. MATERIAL AND METHODS: Between 1997 and 2002 all patients treated with radical cystectomy within 3 months after diagnosis of primary bladder cancer without distant metastasis were retrieved through the Swedish Bladder Cancer Registry. A follow-up questionnaire was distributed to all units where the primary registration of patients was performed. Follow-up data on recurrence date were retrieved from the patient charts and causes of death were obtained from the Swedish Cause of Death Registry until 2003. RESULTS: During the study period radical cystectomy was performed in 39 units in Sweden, of which only five units were considered high-volume hospitals performing 10 or more procedures annually. Mean blood loss was 2300 ml (median 2000 ml) and the 90-day mortality rate was 5.7%. Blood loss was higher in high-volume units than in hospitals with lower hospital volumes, but the 90-day mortality rates were similar. During a median follow-up of 3.5 years, 24% of the patients were submitted to a reoperation. Reoperation rates were significantly higher in patients who received a continent urinary diversion (29%) compared with an ileal conduit (22%, p < 0.015). CONCLUSIONS: Radical cystectomy was associated with a reoperation rate of 24% in Sweden during the study period. The reoperation rates were higher in patients receiving a continent cutaneous diversion or bladder substitution. Blood loss was higher in high-volume units; otherwise, surgical volume did not affect mortality rates, cancer-specific survival or reoperation rates.

Anxiety associated with prostate cancer screening with special reference to men with a positive screening test (elevated PSA) - Results from a prospective, population-based, randomised study.

Levels of anxiety were assessed through questionnaires completed by 1781 screen-positive (PSA > or = 3 ng/mL) men attending the European Randomised Study of Screening for Prostate Cancer in Gothenburg, Sweden. During the first visit (clinical examination, including biopsies), no anxiety whilst awaiting the PSA test results was reported by 66% and 2% reported high levels of anxiety. A multinomial logistics model for repeated measurements, adjusted for age, PSA level, heredity, biopsy finding and urinary symptoms, revealed that anxiety awaiting the PSA was only influenced (increased) by the existence of previously elevated PSA tests (p<.0001). No anxiety associated with biopsy was reported by 45%, while 6% experienced high levels of anxiety. Levels of anxiety decreased significantly with subsequent rounds of examinations (p<0.0001) and with increasing age (p=0.0016). Anxiety associated with prostate cancer screening in general is low to moderate, even in men with elevated PSA, and severe anxiety affects a smaller group of susceptible men.
