- Aims: This study investigated the association between domestic work and self-rated health among women and men in the general population. Methods: The study is based on women (N = 12,910) and men (N = 9784) aged 25-64 years, who responded to a survey questionnaire in 2008 (response rate 56%). Logistic regression models were used to assess the association adjusting for age, educational level, employment status, family status and longstanding illness. Population attributable risks (PAR) were calculated to assess the contribution of domestic work to the prevalence of suboptimal self-rated health. Results: More women (29%) than men (12%) spent more than 20 hours per week in domestic work. Women also experienced domestic work more often as burdensome. Disability pensioners and single mothers reported highest levels of burdensome domestic work. There was a strong independent association between burdensome domestic work and suboptimal self-rated health both in women and men. The PAR for burdensome domestic work was 21% in women and 12% in men and comparable to other major risk factors. Conclusions: The results suggest that domestic work should not be omitted when considering factors that affect self-rated health in the general population.

- Background: The aim was to investigate trends in the prevalence of obesity by age and level of education in the general population in mid-Sweden from year 2000 to 2012. Methods: A postal questionnaire was sent to a random population sample aged 25-74 years in years 2000, 2004, 2008 and 2012. The overall response rates were 67%, 65%, 60% and 53%, respectively, and the study included 29 017, 27 385, 25 910 and 24 152 respondents, respectively. Obesity (BMI a parts per thousand yen 30 kg/m(2)) was based on self-reported weight and height. Results: The age-standardized prevalence of obesity increased from 13% to 17% in women and from 12% to 17% in men between 2000 and 2012. Obesity increased in all age groups from 2000 to 2008 and continued to increase among the middle aged (45-64 years) between 2008 and 2012. The socioeconomic gradient in obesity changed during the study period since the absolute increase in obesity was steepest at the middle educational level. In 2012, the prevalence of obesity was almost twice as high at both middle and low educational levels compared with high educational level. The 'true' prevalence of adult obesity, corrected for self-reported weight and height, was around 20% in 2012 for both men and women. Conclusion: In the majority, among the middle-aged and those with secondary education, the prevalence of obesity continued to increase even between 2008 and 2012.

Ingår i: BMC Urology. - : BioMed Central (BMC). - 1471-2490. ; 24:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Upper tract urothelial carcinoma (UTUC) is a rare malignancy, with typically only few new cases annually per urological department. Adherence to European association of urology (EAU) guidelines on UTUC in the Nordic countries is unknown. The objective of this survey was to examine the implementation of EAU guidelines, the perioperative management and organization of the treatment of UTUC in the Nordic countries.METHODS: The electronic survey was distributed to 93 hospitals in the Nordic countries performing radical nephroureterectomy (NU). The survey consisted of 57 main questions and data was collected between December 1st, 2021 and April 23rd, 2022.RESULTS: Overall response rate was 47/93 (67%) with a completion rate of 98%. Five out of the 6 examined subjects on diagnostic practice are applied by ≥ 72% of the participating centers. NU as treatment for high-risk UTUC is performed by 37/47 (79%), and 91% include a bladder cuff excision.CONCLUSIONS: Adherence to EAU guidelines is high on diagnostic practice in the Nordic countries, whereas disease management is less coherent.

- African Americans are disproportionately affected by type 2 diabetes (T2DM) yet few studies have examined T2DM using genome-wide association approaches in this ethnicity. The aim of this study was to identify genes associated with T2DM in the African American population. We performed a Genome Wide Association Study (GWAS) using the Affymetrix 6.0 array in 965 African-American cases with T2DM and end-stage renal disease (T2DM-ESRD) and 1029 population-based controls. The most significant SNPs (n = 550 independent loci) were genotyped in a replication cohort and 122 SNPs (n = 98 independent loci) were further tested through genotyping three additional validation cohorts followed by meta-analysis in all five cohorts totaling 3,132 cases and 3,317 controls. Twelve SNPs had evidence of association in the GWAS (P<0.0071), were directionally consistent in the Replication cohort and were associated with T2DM in subjects without nephropathy (P<0.05). Meta-analysis in all cases and controls revealed a single SNP reaching genome-wide significance (P<2.5×10(-8)). SNP rs7560163 (P = 7.0×10(-9), OR (95% CI) = 0.75 (0.67-0.84)) is located intergenically between RND3 and RBM43. Four additional loci (rs7542900, rs4659485, rs2722769 and rs7107217) were associated with T2DM (P<0.05) and reached more nominal levels of significance (P<2.5×10(-5)) in the overall analysis and may represent novel loci that contribute to T2DM. We have identified novel T2DM-susceptibility variants in the African-American population. Notably, T2DM risk was associated with the major allele and implies an interesting genetic architecture in this population. These results suggest that multiple loci underlie T2DM susceptibility in the African-American population and that these loci are distinct from those identified in other ethnic populations.

- Optically active 2-thiazolines 4 were previously reported to react with acyl Meldrum's acid derivatives 5 under acidic conditions (HCl (g) in benzene) to stereoselectively give 6-acylpenams 1. Recently we have discovered that the structure elucidation of these compounds was incorrect. Thus, we report new data showing that instead of acyl -lactams, the optically active isomers 3R,9R-1,3-oxazinones 3a-g are obtained stereoselectively in 38-93% yields.

Offshore underwater substation for wave energy converter arrays
- 2010

Tidskriftsartikel (refereegranskat)abstract
- In this study, the design, construction, deployment and operation of an offshore underwater substation is discussed. The seabed placed substation interconnects three linear generator wave energy converters (WECs) at the Swedish Lysekil wave energy research site. The power from the WECs fluctuates because of their direct-driven topology. The generator voltage has varying electrical frequency and amplitude. To reduce the fluctuations, the individual voltages of the WECs are rectified and the power is added on a common DC-bus in the substation. The voltage is inverted, transformed and power is transmitted to an on-shore resistive load. The substation was retrieved on two occasions since the deployment in the spring of 2009. The functionality of the substation is validated by comparing voltage and current wave forms from Simulink with measured results from laboratory experiments. In addition, a sample of results from real offshore operation is illustrated and discussed. With a proportional-integral-derivative (PID)-regulator in the inverter control, the small fluctuations in the DC-bus voltage could be minimised. However, this would reduce the energy storage capability of the DC-link smoothing capacitors.

- Amyloid beta (Aβ) peptides, which aggregate to form neocortical plaques in Alzheimer's disease, exist in states that range from soluble monomers and oligomers/protofibrils to insoluble fibrillar amyloid. The present study evaluated the effects of mAb158, a mouse monoclonal antibody version of lecanemab that preferentially binds to soluble Aβ protofibrils, in aged transgenic mice (Tg2576) with Aβ pathology. Female Tg2576 mice (12 months old) received weekly intraperitoneal mAb158 (35 mg/kg) or vehicle for 4 weeks or for 18 weeks, with or without a subsequent 12-week off-treatment period. Aβ protofibril levels were significantly lower in mAb158-treated animals at both 4 and 18 weeks, while longer treatment duration (18 weeks) was required to observe significantly lower Aβ42 levels in insoluble brain fractions and lower Aβ plaque load. Following the off-treatment period, comparison of the vehicle- and mAb158-treated mice demonstrated that the Aβ protofibril levels, insoluble Aβ42 levels and Aβ plaque load remained significantly lower in mAb158-treated animals, as compared with age-matched controls. However, there was a significant increase of brain accumulation of both the Aβ protofibril levels, insoluble Aβ42 levels and Aβ plaque load after treatment cessation. Thus, repeated mAb158 treatment of aged Tg2576 mice first reduced Aβ protofibril levels within 4 weeks of treatment, which then was followed by a reduction of amyloid plaque pathology within 18 weeks of treatment. These effects were maintained 12 weeks after the final dose, indicating that mAb158 had a disease-modifying effect on the Aβ pathology in this mouse model. In addition, brain accumulation of both Aβ protofibril levels and amyloid pathology progressed after discontinuation of the treatment which supports the importance of continued treatment with mAb158 to maintain the effects on Aβ pathology.
