- Carbon monoxide is thought to be cytoprotective and may hold therapeutic promise for mitigating ischaemic injury. The purpose of this study was to test low-dose carbon monoxide for protective effects in a porcine model of acute myocardial ischaemia and reperfusion. In acute open-thorax experiments in anaesthetised pigs, pretreatment with low-dose carbon monoxide (5% increase in carboxyhaemoglobin) was conducted for 120 min before localised ischaemia (45 min) and reperfusion (60 min) was performed using a coronary snare. Metabolic and injury markers were collected by microdialysis sampling in the ventricular wall. Recovery of radio-marked calcium delivered locally by microperfusate was measured to assess carbon monoxide treatment effects during ischaemia/reperfusion on the intracellular calcium pool. Coronary occlusion and ischaemia/reperfusion were analysed for 16 animals (eight in each group). Changes in glucose, lactate and pyruvate from the ischaemic area were observed during ischaemia and reperfusion interventions, though there was no difference between carbon monoxide-treated and control groups during ischaemia or reperfusion. Similar results were observed for glycerol and microdialysate Ca-45(2+) recovery. These findings show that a relatively low and clinically relevant dose of carbon monoxide did not seem to provide acute protection as indicated by metabolic, energy-related and injury markers in a porcine myocardial ischaemia/reperfusion experimental model. We conclude that protective effects of carbon monoxide related to ischaemia/reperfusion either require higher doses of carbon monoxide or occur later after reperfusion than the immediate time frame studied here. More study is needed to characterise the mechanism and time frame of carbon monoxide-related cytoprotection.

- Background: Pakistan is a patriarchal society where men are the primary authority figures and women are subordinate. This has serious implications on women’s and men’s life prospects. Objective: The aim was to explore current gender roles in urban Pakistan, how these are reproduced and maintained and influence men’s and women’s life circumstances. Design: Five focus group discussions were conducted, including 28 women representing employed, unemployed, educated and uneducated women from different socio-economic strata. Manifest and latent content analyses were applied. Findings: Two major themes emerged during analysis: ‘Reiteration of gender roles’ and ‘Agents of change’. The first theme included perceptions of traditional gender roles and how these preserve women’s subordination. The power gradient, with men holding a superior position in relation to women, distinctive features in the culture and the role of the extended family were considered to interact to suppress women. The second theme included agents of change, where the role of education was prominent as well as the role of mass media. It was further emphasised that the younger generation was more positive to modernisation of gender roles than the elder generation. Conclusions: This study reveals serious gender inequalities and human rights violations against women in the Pakistani society. The unequal gender roles were perceived as static and enforced by structures imbedded in society. Women routinely faced serious restrictions and limitations of autonomy. However, attainment of higher levels of education especially not only for women but also for men was viewed as an agent towards change. Furthermore, mass media was perceived as having a positive role to play in supporting women’s empowerment.

Journal article (peer-reviewed)abstract
- Objectives: To determine the health-related quality of life (HRQOL) and its relationship to disease variables, vertebral fractures, and employment status in female patients with systemic lupus erythematosus (SLE). Methods: HRQOL was assessed with the Swedish version of the Medical Outcomes Study (MOS) 36-Item Short Form Survey (SF-36) in female patients (n=163) and in age- and sex-matched controls (n=1045). Associations between the SF-36 score and demographics, disease variables, prevalent vertebral fractures, and employment status were analysed. Results: The SLE patients, aged 20 to 82 years, scored significantly lower than the controls on all SF-36 subscales. Patients with vertebral fractures were older, had greater disease damage, and lower physical functioning (PF) than patients without fractures. Of the SLE patients of working age (n=142), 54% worked full or part time. These patients scored their HRQOL significantly higher (better) than patients not working. Being able to work was significantly associated with low age and high scores in PF and role physical (RP): the area under the receiver operating characteristic (ROC) curve for these variables was 0.82, confidence interval 0.75-0.89. Conclusions: HRQOL is substantially lower in SLE than in the general population but working ability indicates better health. We encourage further research regarding the effects on HRQOL by preventive actions taken against work disability in SLE.

- ABSTRACT: INTRODUCTION: Our objective was to determine the frequency of and factors associated with prevalent vertebral compression fractures in female SLE patients attending rheumatologists in Western Sweden. METHODS: In this cross sectional study 150 women were included. They were examined with x-ray of thoracic and lumbar spine (Th4-L4). A reduction of at least 20% of any vertebral height, assessed by Genant's semiquantitative method, was defined as a fracture. Bone mineral density (BMD) was measured by dual energy x-ray absorptiometry (DXA). RESULTS: Median patient age was 47 years (20-82) and disease duration 11 years (1-41). Only 6 (4%) women had a history of clinical compressions whereas 43 (29%) had at least one radiological fracture each. The patients with at least one fracture at any site were characterized by higher age (p<0.001), being postmenopausal (p<0.01), higher Systemic Lupus International Collaborative Clinics Damage Index (p<0.05), lower BMD total hip and femoral neck (p<0.05), more peripheral fractures (p< 0.01), medication with bisphosphonates (p<0.05) and calcium and vitamin D3 (p<0.05). There were no significant differences regarding current or cumulative glucocorticosteroid dose between the groups. In logistic regression analyses high age remained as risk factor of at least one vertebral fracture at any site whereas low BMD in total hip was associated with vertebral fracture in lumbar spine. CONCLUSION: Radiological compression fractures are common but seldom diagnosed in SLE patients. High age and low BMD in total hip, but not in spine, was associated with vertebral fractures.

Journal article (peer-reviewed)abstract
- Studying gene-environment interactions requires that the amount and quality of the lifestyle data is comparable to what is available for the corresponding genomic data. Sweden has several crucial prerequisites for comprehensive longitudinal biomedical research, such as the personal identity number, the universally available national health care system, continuously updated population and health registries and a scientifically motivated population. LifeGene builds on these strengths to bridge the gap between basic research and clinical applications with particular attention to populations, through a unique design in a research-friendly setting. LifeGene is designed both as a prospective cohort study and an infrastructure with repeated contacts of study participants approximately every 5 years. Index persons aged 18-45 years old will be recruited and invited to include their household members (partner and any children). A comprehensive questionnaire addressing cutting-edge research questions will be administered through the web with short follow-ups annually. Biosamples and physical measurements will also be collected at baseline, and re-administered every 5 years thereafter. Event-based sampling will be a key feature of LifeGene. The household-based design will give the opportunity to involve young couples prior to and during pregnancy, allowing for the first study of children born into cohort with complete pre-and perinatal data from both the mother and father. Questions and sampling schemes will be tailored to the participants' age and life events. The target of LifeGene is to enrol 500,000 Swedes and follow them longitudinally for at least 20 years.

Journal article (peer-reviewed)abstract
- The translocation t(1;19)(q23;p13)/der(19) t(1;19) is a risk stratifying aberration in childhood B-cell precursor acute lymphoblastic leukaemia (BCP ALL) in the Nordic countries. We have identified 47 children/adolescents with t(1;19)/der(19) t(1;19)-positive BCP ALL treated on two successive Nordic Society of Paediatric Haematology and Oncology (NOPHO) protocols between 1992 and 2007 and have reviewed the clinical and cytogenetic characteristics of these cases, comprising 1.8% of all cases. The translocation was balanced in 15 cases (32%) and unbalanced in 29 cases (62%). The most common additional chromosome abnormalities were del(9p), i(9q), del(6q), and del(13q). The median age was 7 years, the median white blood cell (WBC) count was 16 x 10(9)/l, and the female/male ratio was 1.2. The predicted event-free survival (EFS) at 5 and 10 years was 0.79, whereas the predicted overall survival (OS) at 5 and 10 years was 0.85 and 0.82, respectively. Nine patients had a bone marrow relapse after a median of 23 months; no patient had a central nervous system relapse. Additional cytogenetic abnormalities, age, gender, WBC count or whether the t(1;19) was balanced or unbalanced did not influence EFS or OS. Compared to cases with t(12,21) and high hyperdiploidy, EFS was similar, but overall survival was worse in patients with t(1;19)/der(19) t(1;19) (P = 0.004).

Impacts of the Productive Safety Net Program in Ethiopia on livestock and tree holdings of rural households
- 2011

In: Journal of Development Economics. - : Elsevier BV. - 0304-3878 .- 1872-6089. ; 94:1, s. 119-126

Journal article (peer-reviewed)abstract
- We evaluated the impacts of the Ethiopian Productive Safety Net Program (PSNP) on rural households' holdings of livestock and forest assets/trees. We found no indication that participation in PSNP induces households to disinvest in livestock or trees. In fact, households that participated in the program increased the number of trees planted, but there was no increase in their livestock holdings. We found no strong evidence that the PSNP protects livestock in times of shock. Shocks appear to lead households to disinvest in livestock, but not in trees. Our results suggest that there is increased forestry activity as a result of PSNP, and that improved credit access encourages households to increase their livestock holdings.
