- The high resistance to malaria in the nomadic Fulani population needs further understanding. The ability to cope with multiclonal Plasmodium falciparum infections was assessed in a cross-sectional survey in the Fulani and the Dogon, their sympatric ethnic group in Mali. The Fulani had lower parasite prevalence and densities and more prominent spleen enlargement. Spleen rates in children aged 2–9 years were 75% in the Fulani and 44% in the Dogon (P < 0.001). There was no difference in number of P. falciparum genotypes, defined by merozoite surface protein 2 polymorphism, with mean values of 2.25 and 2.11 (P = 0.503) in the Dogon and Fulani, respectively. Spleen rate increased with parasite prevalence, density and number of co-infecting clones in asymptomatic Dogon. Moreover, splenomegaly was increased in individuals with clinical malaria in the Dogon, odds ratio 3.67 (95% CI 1.65–8.15, P = 0.003), but not found in the Fulani, 1.36 (95% CI 0.53–3.48, P = 0.633). The more susceptible Dogon population thus appear to respond with pronounced spleen enlargement to asymptomatic multiclonal infections and acute disease whereas the Fulani have generally enlarged spleens already functional for protection. The results emphasize the importance of spleen function in protective immunity to the polymorphic malaria parasite.

- Background: The perioperative effects of intrathecal and epidural clonidine combined with local anesthetic were evaluated in 60 patients undergoing hip arthroplasty.Methods: This was a double-blinded study and the patients were randomized into three groups, with 20 patients in each group. All patients received spinal anesthesia with 17.5 mg of plain bupivacaine with 15 µg of clonidine (Group BC-RC) or without clonidine (Groups B-R and B-RC). Postoperatively, epidural infusion was administered in the following way: Group B-R – ropivacaine 4 mg h−1; Groups B-RC and BC-RC: ropivacaine 4 mg h−1 and clonidine 40 µg h−1. Sensory block was assessed with light touch, pinprick, transcutaneous electrical stimulation at T12 and L2 dermatomes, and perception of thermal stimuli.Results: The maximal upper level of sensory block measured by pin-prick (T6–T7) did not differ between the groups while the partial sensory block for cold and warmth were increased two dermatomes above pin-prick level in the group with intrathecal clonidine compared to the other two groups (P < 0.05). Duration of anesthesia, analgesia and motor block were longer in Group BC-RC compared to Groups B-R and B-RC (P < 0.02). Postoperatively, both VAS score on movement and PCA-morphine consumption were higher in Group B-R than in Groups B-RC and BC-RC (P < 0.01). The arterial pressure and heart rate in Groups B-RC and BC-RC were significantly lower than in Group B-R at 10–24 and 15–24 h, respectively, after spinal injection.Conclusion: Low-dose intrathecal clonidine provided a better quality of anesthesia and longer-lasting analgesia. Epidural clonidine-ropivacaine infusion resulted in improved postoperative analgesia but was associated with a moderate decrease in blood pressure.

Tidskriftsartikel (refereegranskat)abstract
- Different waste treatment options for municipal solid waste have been studied in a systems analysis. Different combinations of incineration, materials recycling of separated plastic and cardboard containers, and biological treatment (anaerobic digestion and composting) of biodegradable waste, were studied and compared to landfilling. The evaluation covered use of energy resources, environmental impact and financial and environmental costs. In the study, a calculation model ( ) based on methodology from life cycle assessment (LCA) was used. Case studies were performed in three Swedish municipalities: Uppsala, Stockholm, and Älvdalen. The study shows that reduced landfilling in favour of increased recycling of energy and materials lead to lower environmental impact, lower consumption of energy resources, and lower economic costs. Landfilling of energy-rich waste should be avoided as far as possible, partly because of the negative environmental impacts from landfilling, but mainly because of the low recovery of resources when landfilling. Differences between materials recycling, nutrient recycling and incineration are small but in general recycling of plastic is somewhat better than incineration and biological treatment somewhat worse. When planning waste management, it is important to know that the choice of waste treatment method affects processes outside the waste management system, such as generation of district heating, electricity, vehicle fuel, plastic, cardboard, and fertiliser.

- OBJECTIVE: To compare the effect of a land-based, physical exercise program versus water aerobics on low back or pelvic pain and sick leave during pregnancy. DESIGN: Randomized controlled clinical trial. SETTING: Three antenatal care centers. PARTICIPANTS: 390 healthy pregnant women. INTERVENTIONS: A land-based physical exercise program or water aerobic once a week during pregnancy. MAIN OUTCOME MEASURES: Sick leave, pregnancy-related low back pain or pregnancy-related pelvic girdle pain, or both. RESULTS: Water aerobics diminished pregnancy-related low back pain (p=.04) and sick leave due to pregnancy-related low back pain (p=.03) more than a land-based physical exercise program. CONCLUSIONS: Water aerobics can be recommended for the treatment of low back pain during pregnancy. The benefits of a land-based physical exercise program are questionable and further evaluation is needed.

- BACKGROUND AND STUDY AIM: Few previous studies have addressed the agreement between endoscopy and histology regarding Barrett's oesophagus in unselected endoscopy patients. Our aim was to quantify this agreement, and to study its relation to clinical and endoscopic characteristics in consecutive patients coming for first-time gastroscopy. METHODS: We invited consecutive patients aged 18-79 years and endoscoped for the first time at endoscopy units exclusively serving defined catchment areas in southeast Sweden. Endoscopic and clinical data were recorded according to a predetermined protocol, and biopsies were taken from the distal oesophagus in all patients. RESULTS: Among 705 patients included, 17% [95% confidence interval (CI): 14-20] had endoscopically visible columnar mucosa above the oesophagogastric junction and 38% (95% CI: 34-42) had columnar mucosa in at least one biopsy irrespective of the endoscopic finding. The overall concordance between endoscopy and histology regarding presence (or absence) of columnar mucosa above the oesophagogastric junction was 74% (95% CI: 71-77) and the agreement beyond chance, as measured by Kappa (?) statistics, was fair, ?=0.38 (95% CI: 0.32-0.45). The agreement between the endoscopic assessment and intestinal metaplasia at biopsy was 86% (95% CI: 83-88), but ? was only 0.31 (95% CI: 0.21-0.41). Our data were consistent with a lower threshold for macroscopic detection of columnar epithelium above the oesophagogastric junction, when risk factors for Barrett's oesophagus were present. CONCLUSION: The agreement between macroscopic and microscopic assessments of Barrett's oesophagus is no more than fair, and partly dependent on the presence of patient characteristics suggestive of pathology in this region. © 2007 Lippincott Williams & Wilkins, Inc.

- Objective. Given its often subclinical course, Barrett's oesophagus (BO) hardly lends itself to epidemiologically stringent evaluations. The objective of this study was to investigate risk factors for incident BO diagnosed in a defined population in southeast Sweden while paying particular attention to epidemiological aspects of the study design. Material and methods. Consecutive patients (aged 18-79 years) who were endoscoped with new indications at units exclusively responsible for all gastroscopies in defined catchment area populations were invited to take part in the study. Biopsies were taken above and immediately below the gastro-oesophageal junction, and exposure information was collected through self-administered questionnaires. Endoscopy-room-based cross-sectional data from 604 patients were supplemented with exposure data from 160 population controls. Associations, expressed as odds ratios (ORs), were modelled by means of multivariable logistic regression. Results. In the comparison with population controls, reflux symptoms and smoking indicated a 10.7- and 3.3-fold risk, respectively, for BO (95% confidence interval (CI) 3.5-33.4 and 1.1-9.9, respectively). Body mass was unrelated to risk. In the cross-sectional analysis among endoscopy-room patients, reflux symptoms were associated with an OR of 2.0 (95% CI 0.8-5.0). This association was, however, modified by the subjunctional presence of Helicobacter pylori, although the infection was not in itself significantly connected with risk, a combination of reflux symptoms and H. pylori infection was linked to an almost 5-fold risk (95% CI 1.4-16.5) as compared with the absence of both factors. The BO prevalence increased by 5% per year of age (95% CI 1-9%). Conclusions. Reflux is the predominant risk factor for BO, and proximal gastric colonization of H. pylori seems to amplify this risk. © 2007 Taylor & Francis.

- Aims: Colorectal cancer is the second most common type of cancer in both women and men in Sweden. A National Quality Register for rectal adenocarcinoma in Sweden has included 97% of all rectal cancer patients since 1995. A previous study, based on data from the treatment program register in the Stockholm-Gotland region. found that women in Stockholm received preoperative radiotherapy (RT) less often than men [Martling A. Rectal cancer: staging, radiotherapy and surgery, ISBN: 91-7349-461-5. Stockholm: Karolinska Institute: 2003].(1) The aim of this study was to assess if women and men with rectal cancer receive equal treatment oil a national level, and whether any potential dissimilarity causes measurable consequences in Outcome. regarding postoperative morbidity and mortality, turnout, recurrence and Survival.Methods: All patients with rectal cancer included in the National Quality Register between 1995 and 2002 (11 774 patients) were analysed. Gender was correlated to treatment, postoperative morbidity and mortality, local recurrence and death.Results: The proportion of women selected for preoperative RT was significantly lower than that of men (42.5% vs. 50.1%, p < 0.001). After adjustment for other prognostic factors, the significant difference in the treatment strategy among women and men persisted. Postoperative mortality was significantly higher in men than in women and the gender difference was most pronounced in irradiated patients. RT improved local control significantly in both women and men but it had no effect oil cancer specific survival.Conclusions: For unknown reasons women less often received adjuvant RT than men. The opposite appeared to be a more adequate alternative. There is a need of improved selection criteria for RT in both men and women with rectal cancer.
