Students’ and teachers’ attitudes towards PBL-curriculum components in a medical programme – a follow-up study
Objective: The aim was to explore students’ and teachers’ attitudes towards horizontal and vertical integration and other components of the curriculum, and to compare these results with data from a study at our medical school published in 2002. Methods: A questionnaire with 17 questions regarding different components of our curriculum was sent to students and staff at our medical school. They were asked to rate the importance of different components on a Likert scale from 1-6. We compared the answers between the two groups, and also compared them with the results from 2002. Results: Horizontal and vertical integration were rated as very important components (Teachers (n=283) median 5 and 5, Students (n=596) 6 and 5 respectively). Students valued lectures and clinical rotations more highly than teachers. Teachers considered laboratory training, training in searching scientific literature, scientific projects, basic education in ethics, reading and discussion of fictional literature, interprofessional components and examinations as significantly more important than the students did. Conclusions: Attitudes have remained positive towards horizontal and vertical integration despite major changes in the curriculum. The majority of the components of our curriculum were well appreciated, indicating that our curriculum is robust, but some components warrant inspection and possible revision.

Self‐reported mental health and cortisol activity at 27‐28 years of age in individuals born with very low birthweight
Aim To assess mental health outcomes of very low birth weight (VLBW, <1500 g) subjects to adulthood, and to examine salivary cortisol and hair cortisol levels and their relation to birth characteristics and mental health. Methods A Swedish regional cohort of 56 VLBW subjects and 55 full‐term controls were assessed at the ages 27‐ 28 with adult self‐reported scales and the mean of 2 days diurnal salivary cortisol and hair cortisol. The cohorts had been assessed at 15 years of age with youth self‐reported scales. Results There were no differences between the groups in youth self‐reported scales and adult self‐reported scores. The 24 participating VLBW girls scored lower on youth self‐reported scales externalising and total problem scores than the control girls. In adulthood, the 21 participating VLBW women had significantly higher morning concentrations of salivary cortisol than control women, p=0.014. No significant associations were found between cortisol concentrations and adult self‐reported scales internalising, externalising, and total scores. Conclusion Self‐reported mental health in VLBW subjects was comparable with normal birth weight controls indicating a satisfying transition from adolescence to adulthood. VLBW females had higher morning salivary cortisol concentrations, suggesting a gender difference. We found no correlations between cortisol and mental health.

Reduced Need for Rescue Antiemetics and Improved Capacity to Eat in Patients Receiving Acupuncture Compared to Patients Receiving Sham Acupuncture or Standard Care during Radiotherapy
Objective. To evaluate if consumption of emesis‐related care and eating capacity differed between patients receiving verum acupuncture, sham acupuncture, or standard care only during radiotherapy. Methods. Patients were randomized to verum (n = 100) or sham (n = 100) acupuncture (telescopic blunt sham needle) (median 12 sessions) and registered daily their consumption of antiemetics and eating capacity. A standard care group (n = 62) received standard care only and delivered these data once. Results. More patients in the verum (n = 73 of 89 patients still undergoing radiotherapy; 82%, Relative Risk (RR) 1.23, 95% Confidence Interval (CI) 1.01–1.50) and the sham acupuncture group (n = 79 of 95; 83%, RR 1.24, CI 1.03–1.52) did not need any antiemetic medications, as compared to the standard care group (n = 42 out of 63; 67%) after receiving 27 Gray dose of radiotherapy. More patients in the verum (n = 50 of 89; 56%, RR 1.78, CI 1.31–2.42) and the sham acupuncture group (n = 58 of 94 answering patients; 62%, RR 1.83, CI 1.20–2.80) were capable of eating as usual, compared to the standard care group (n = 20 of 63; 39%). Conclusion. Patients receiving acupuncture had lower consumption of antiemetics and better eating capacity than patients receiving standard antiemetic care, plausible by nonspecific effects of the extra care during acupuncture.

Elderly men with a history of distal radius fracture have significantly lower calcaneal bone density and free androgen index than age-matched controls
Background: Age related bone loss is widely accepted as related to decreased serum levels of circulating sex hormones. Epidemiological data also show distal radius fractures in men to be a sensitive marker of bone fragility. The aim of this study was to assess if men with a history of distal radius fracture have lower bone mass density (BMD), lower free androgen index (FAI), lower total testosterone (T) and lower bio-available testosterone (Bio-T) than healthy age-matched controls. Patients and methods: A case-control study is based on consecutive cases treated for low energy distal radius fracture at our department and age-matched controls. Thirty-nine men treated between 1997–2004 and 45 age-matched controls underwent calcaneal bone density measurements (t-score) and analyses of T, Bio-T and serum hormone binding globulin (SHBG). Results: The fracture group had lower BMD (p < 0.01) and lower FAI (p = 0.01). Linear regression analysis showed a correlation between Bio-T and t-scores (p = 0.03). Using analysis of covariance, a significant difference with lower Bio-T in the fracture group was shown. Conclusion: Bio-T seems to correlate with BMD in elderly men and may serve as a marker for increased fracture risk in this patient group.

Symptoms of multiple sclerosis in women in relation to cyclical hormone changes
Objectives To prospectively investigate if women with multiple sclerosis (MS) experience changes in MS-symptoms in relation to cyclical hormonal changes. Methods Sixty-three women with MS, either with regular, spontaneous menstrual cycles or taking combined oral contraceptives (COCs), were asked to score their MS symptoms every day during three cycles. Symptom scores were analysed in relation to different phases of the spontaneous menstrual- or pill-driven cycle. Results Twenty-three women completed the score record. Among the 16 women who were not using a COC there were no significant differences in symptom scores between the phases of the menstrual cycle. The seven women taking a COC reported significantly higher symptom score points for weakness, numbness and tiredness during the pill-free interval compared with the phase during which they took the COC daily. Conclusions This prospective study appears to contradict earlier retrospective studies regarding variations in MS symptoms in relation to the menstrual cycle in women who are not using a COC. The lower symptom scores during the three weeks of pill taking suggest a positive effect of the steroids on the manifestations of MS. Further studies concerning both short- and long-term effects of OC-use on MS symptoms are needed.
