Forskningsöversikt (refereegranskat)abstract
- We summarise the findings of arthropods collected by fogging the canopy of 24 pine trees in two sites in Eastern and Western Norway. From the samples, taken in 1998 and in 1999, almost 30,000 specimens were determined to 512 species, with Diptera being most species rich (210 species), followed by Coleoptera (76 species) and Araneae (49 species). Of the 96 new species records, nine were new to science (5 Diptera and 4 Oribatida), two were new to the European, three to the Scandinavian and 82 to the Norwegian faunas. The paper demonstrates the need for detailed faunistical inventories of European forests.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To examine a possible relationship between baseline albuminuria and effect of losartan versus atenolol on cardiovascular (CV) events in hypertensive patients with left ventricular hypertrophy, the effect of losartan versus atenolol on albuminuria, and whether the benefits of losartan versus atenolol could be explained by influence of losartan on albuminuria. DESIGN: Double-blind, randomized, controlled trial of 4.8 years. SETTING: Out-patient setting. PATIENTS: A total of 8206 with hypertension and left ventricular hypertrophy. INTERVENTIONS: Losartan or atenolol, supplemented with diuretics and/or calcium antagonists to reach blood pressure < 140/90 mmHg MAIN OUTCOME MEASURES: The urine albumin/creatinine ratio, and the primary composite endpoint (CEP) of CV death, myocardial infarction, and stroke. RESULTS: The blood pressure was reduced similarly on losartan (30.2/16.6 mmHg) versus atenolol (29.1/16.8 mmHg). The risk of a primary CEP increased linearly from the lowest to the highest decile of baseline albuminuria. The benefits of losartan versus atenolol for the primary CEP and for stroke tended to be more pronounced among patients above the median value for baseline albuminuria (urine albumin/creatinine ratio, 1.28 mg/mmol). The decrease in albuminuria was significantly greater with losartan versus atenolol throughout the study (a decrease from baseline to year 2 of 33% losartan versus 25% atenolol). One-fifth of the difference in favor of losartan on the primary CEP was explained by the greater reduction in albuminuria on losartan. CONCLUSIONS: Baseline albuminuria is a powerful risk factor for CV events. Baseline albuminuria did not identify the group of patients with greatest benefit on losartan versus atenolol in LIFE. Reduction in albuminuria explained one-fifth of the benefits of losartan versus atenolol.

Tidskriftsartikel (refereegranskat)abstract
- Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment area of the cases. Histological review performed by a reference pathologist left 99 cases for study; 84 cases and 2070 population controls were interviewed. The industries most closely associated (a twofold or more odds ratio [OR]) with SBC taking into account a 10-year time lag after exposure were, among women, employment in wholesale industry of food and beverages (OR, 8.2; 95% confidence interval [CI], [1.9 to 34.9]) and among men, manufacture of motor vehicle bodies (OR, 5.2; 95% CI, 1.2 to 22.4), footwear (OR, 3.9: 95% CI, 0.9 to 16.1), and metal structures (OR, 3.3; 95% CI, 1.0 to 10.4). The identified high-risk occupations with all OR above 2 were shoemakers, structural metal preparers, construction painters and other construction workers. bookkeepers, machine fitters, and welders (men). The OR for regular occupational use of organic. solvents for at least half a year was 2.0 (95% CI, 1.0 to 4.2). Exposure to rust-preventive paint containing lead was suggested as another potential occupational exposure (OR, 9.1; 95% CI, 0.8 to 107). This explorative study suggests an association between certain occupational exposures and SBC, bill some of these associations could be attributable to chance. All findings should be regarded as tentative.

The importance of smoking and medical history for development of small bowel carcinoid tumor: a European population-based case-control study
- 2002
-
Ingår i: Cancer Causes and Control. - 1573-7225. ; 13:1, s. 27-34
-
Tidskriftsartikel (refereegranskat)abstract
- Objective: Little is known about the etiology of small bowel carcinoid tumor (SBC), but a few studies have pointed to certain medical and lifestyle factors as potential risk factors. This study aims to evaluate these findings and to identify new associations. Methods: A population-based European multicenter case-control study was conducted from 1995 through 1997. Incident histologically verified 35-69 year-old SBC cases (n = 99) and 3335 controls were recruited; 84 cases and 2070 controls were interviewed. Results: Ever being a smoker was associated with SBC (odds ratio = 1.9; 95% confidence interval 1.1-3.2) and increased risk estimates were seen for all smoking categories. SBC was associated with previous gallstone disease and ovariectomy, but only when these conditions occurred within two years prior to the SBC diagnosis. No association was seen for a history of cholecystitis, liver cirrhosis, ulcerative disease, or Crohn's disease. Intake of alcoholic beverages - as well as medical treatments with radioactive substances, hormones, or corticosteroid tablets - were not associated with SBC. Conclusions: This study indicates that tobacco smoking is a risk factor for SBC. The associations with gallstone and ovarian diseases may be due to enhanced medical surveillance during the early phase of the cancer disease.

Tidskriftsartikel (refereegranskat)abstract
- Study Design. A randomized controlled comparative trial with an 8-month follow-up period was conducted. Objective. To compare the effect of the McKenzie treatment method with that of intensive dynamic strengthening training in patients with subacute of chronic low back pain. Summary of Backround Data. Randomized studies indicate that the efficacy of the McKenzie method in the treatment of patients with acute or subacute low back-pain is debatable. Currently, no randomized studies examining the effects of this method for patients with chronic low back pain have been published. Methods. For this study, 260 consecutive patients with low back pain and at least 8 weeks duration of symptons (85% of the patients had more than 3 months duration of symptoms) were randomized into two groups: Group A was treated with the McKenzie method (n = 132), and Group B was treated with intensive dynamic strengthening training (n = 128). The treatment period for both groups was 8 weeks at an outpatient clinic, followed by 2 months of self-training at home. Treatment results were recorded at the end of the treatment period at the clinic, then 2 and 8 months after. In both groups, 30% of the patients were lost to follow-up evaluation. An intention-to-treat analysis of the main effect variables, disability, and pain was perfromed for all the patients included in the study. A supplementaty analysis of the 180 patients who completed the full treatment program also was undertaken. Results. Intention-to-treat analysis showed a tendency toward a difference in reduction of disability in favor of the McKenzie group at the 2-month follow-up assessment (P = 0.04), but no differences at the end of treatment and at the 8-month follow-up evaluation. No differences in reduction of pain were observed at any time between the groups. The supplementary analysis of the patients who had completed the full intervention showed a tendency toward a difference in favour of the McKenzie method in reduction of pain at the end of treatment (P = 0.02). This difference reached statistical significance at the 2-month follow-up assessment (P= 0.01), but no difference was found after 8 months. The supplementary analysis showed no differences between the groups with regard to reduction of disability. Conclusion. The McKenzie method and intensive dynamic strengthening training seem to be equally effective in the treatment of patients with subacute or chronic low back pain.

Limited protective effect of the CCR5 Delta 32/CCR5 Delta 32 genotype on human immunodeficiency virus infection incidence in a cohort of patients with hemophilia and selection for genotypic X4 virus
- 2003
-
Ingår i: Journal of Infectious Diseases. - 1537-6613. ; 187:2, s. 215-225
-
Tidskriftsartikel (refereegranskat)abstract
- The relationship among CCR5 genotype, cytomegalovirus infection, and disease progression and death was studied among 159 human immunodeficiency virus (HIV)-infected patients with hemophilia. One patient (0.6%) had the CCR5Delta32/CCR5Delta32 genotype (which occurs in similar to2% of the Scandinavian population) and a rapid disease course. His HIV V3 region contained genotypic features attributable to X4 virus and resembled functionally verified X4 virus and virus from patients treated with a CD4 cell-stimulating drug, tucaresol. Age-related differences in disease progression rate and survival time were seen for CCR5/CCR5 patients. Surprisingly, no protective effect of the CCR5/CCR5Delta32 genotype on disease progression or survival was seen for children but was evident for adults. Age group-related immunologic differences might explain this variation, and transmission route and/or viral phenotype variation within donor virus may be related to the limited protection of the CCR5Delta32/ CCR5Delta32 genotype. Sequence comparisons indicate that X4 virus can be selected in vivo due to either absence of CCR5 receptors or relative increase of CXCR4 receptors.

Tidskriftsartikel (refereegranskat)abstract
- In this paper we aim to create a reference data collection of Northern blot results and demonstrate how such a collection can enable a quantitative comparison of modern expression profiling techniques, a central component of functional genomics studies. Historic ally, Northern blots were the de facto standard for determining RNA transcript levels. However, driven by the demand for analysis of large sets of genes in parallel, high-throughput methods, such as microarrays, dominate modern profiling efforts. To facilitate assessment of these methods, in comparison to Northern blots, we created a database of published Northern results obtained with a standardized commercial multiple tissue blot (dbMTN). In order to demonstrate the utility of the dbMTN collection for technology comparison, we also generated expression profiles for genes across a set of human tissues, using multiple profiling techniques. No method produced profiles that were strongly correlated with the Northern blot data. The highest correlations to the Northern blot data were determined with microarrays for the subset of genes observed to be specifically expressed in a single tissue in the Northern analyses. The database and expression profiling data are available via the project website (http://www.cisreg.ca). We believe that emphasis on multitechnique validation of expression profiles is justified, as the correlation results between platforms are not encouraging on the whole.

The strengths and difficulties questionnaire in the Nordic countries
- 2004
-
Ingår i: European Child Adolescent Psychiatry. ; 13:suppl 2, s. 1132-9
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The Strengths and Difficulties Questionnaire (SDQ) has been translated into the different Nordic languages between 1996 and 2003. During the past few years, SDQs have been completed for nearly 100,000 children and adolescents in population-based studies as well as in clinical samples. The largest studies have been performed in Norway and Denmark, and in these countries the diagnostic interview DAWBA has also been used in conjunction with the SDQ. AIMS: In addition to a brief overview of past and ongoing SDQ work in Sweden, Finland, Norway, Denmark, and Iceland, we present scale means and standard deviations from selected community studies with comparable age groups, including parental reports for 7, 9 and 11 year-old children and self-reports of 13 and 15 year-olds. CONCLUSIONS: The descriptive statistics suggest that the distributions of SDQ scores are very similar across the Nordic countries. Further collaborative efforts in establishing norms and evaluating the validity of the SDQ as a screening instrument are encouraged.

- The immediate behavioral responses of goldfish (Carassius auratus) to pesticide-contaminated flows were recorded in a countercurrent olfactometer. In addition, electro-olfactograms were recorded from the epithelial surface of the olfactory rosette as a preliminary check for the. olfactory sensitivity of the fish to the pesticides tested. All tests were run on prochloraz (imidazole fungicide), bentazone (diazine herbicide), and nicosulfuron (sulfonylurea herbicide). Behavioral effects were assessed, at four concentrations (10 mug/L, 100 mug/L, 1 mg/L, 10 mg/L), on endpoints related to swimming pattern (preference-avoidance responses, burst swimming reactions), comfort activities (buccal movements, feeding attempts), and social relations (antagonistic acts, grouping). The behavior of the fish appeared particularly sensitive to prochloraz exposure. As a whole, prochloraz-contaminated flows showed significant effects on the six behaviors studied; bentazone and nicosulfuron affected three and five, respectively. At the lowest concentration, prochloraz also showed more effects than the two other pesticides. Some of the behavioral endpoints. were found particularly sensitive to a given chemical. Pesticide-contaminated flows also induced significant changes in swimming orientation of the fish. Attraction was observed in response to flowing solutions of prochloraz (1 mg/L,10 mg/L), bentazone (10 mug/L, 10 mg/L), and nicosulfuron (I mg/L, 10 mg/L). At a concentration of 1 mg/L, none of the pesticides induced a noticeable depolarization of the olfactory epithelium, suggesting that these chemicals are not detected by the olfactory sense of the fish. These results are discussed in the light of the data concerning effects of pesticides on behavior and chemical communication in fish.

Tidskriftsartikel (refereegranskat)abstract
- The behavioral effects of short periods (2, 4, 6, 8 h) of static exposure to prochloraz (imidazole fungicide) and nicosulfuron (sulfonylurea herbicide) were recorded in goldfish (Carassius auratus). Observations were also made in an olfactometer to assess the effects of 8-h exposures to these two pesticides and to carbofuran (carbamate insecticide) on the behavioral responses to the flow of a solution of four L-amino acids (glycine, alanine, valine, taurine), mixed in the same relative proportions as in the urine of conspecifics. Each pesticide was tested at three sublethal concentrations (25, 50, 100 mug/L), and the behaviors recorded were related to swimming pattern, social interactions, and comfort movements. Static exposures to prochloraz affected horizontal displacements, burst swimming, grouping, and buccal movements. Static exposures to nicosulfuron affected burst swimming and grouping. In pesticide-unexposed fish (control), the flow of the amino acid solution induced attraction, decreased sheltering, and increased horizontal displacements, burst swimming, buccal movements, and antagonistic interactions. Compared to the controls, some of the behavioral responses to the solution of amino acids were significantly different after 8 It of subacute exposure to prochloraz and carbofuran. Both pesticides decreased attraction and increased sheltering. In addition, carbofuran decreased buccal movements and antagonistic interactions. Contrastingly, exposure to nicosulfuron showed no significant effect. This study further confirms the great vulnerability of fish behavior and chemocommunication processes to exposure to waterborne pesticides.

Forskningsöversikt (refereegranskat)abstract
- Background: Strategies to prevent children from developing allergy have been elaborated on the basis of state-of-the-art reviews of the scientific literature regarding pets and allergies, building dampness and health, and building ventilation and health. A similar multidisciplinary review of infant feeding mode in relation to allergy has not been published previously. Here, the objective is to review the scientific literature regarding the impact of early feeding (breast milk and/or cow's milk and/or formula) on development of atopic disease. The work was performed by a multidisciplinary group of Scandinavian researchers. Methods: The search in the literature identified 4323 articles that contained at least one of the exposure and health effect terms. A total of 4191 articles were excluded mainly because they did not contain information on both exposure and health effects. Consequently, 132 studies have been scrutinized by this review group. Results: Of the 132 studies selected, 56 were regarded as conclusive. Several factors contributed to the exclusions. The studies considered conclusive by the review group were categorized according to population and study design. Conclusions: The review group concluded that breastfeeding seems to protect from the development of atopic disease. The effect appears even stronger in children with atopic heredity. If breast milk is unavailable or insufficient, extensively hydrolysed formulas are preferable to unhydrolysed or partially hydrolysed formulas in terms of the risk of some atopic manifestations.
