- The study includes medicolegally examined fatal poisonings among drug addicts in 1997 in the five Nordic countries: Denmark, Finland, Iceland, Norway and Sweden, and the results are compared to a similar investigation from 1991. A common definition of "drug addict" was applied by the participating countries. The highest death rate by poisoning in drug addicts was observed in Denmark, where it was 6.54 per 105 inhabitants, followed by Norway with 6.35, Sweden with 2.21, Finland with 1.63 and Iceland with 1.20 per 105 inhabitants. All countries showed a higher death rate in 1997 than in 1991. For all countries the distribution of deaths according to geographical regions showed a decreasing number of drug deaths in the metropolitan area and an increasing number in other cities. Heroin/morphine dominated as the cause of death and was responsible for about 90% of the cases in Norway. In Sweden and Denmark, however, heroin/morphine caused only about 70% of the fatal poisonings. About 30% of the fatal poisonings in Denmark and Sweden were caused by other group I drugs, in Denmark mainly methadone and in Sweden mainly propoxyphene. Apart from two cases in Sweden methadone deaths were not seen in the other Nordic countries. In Finland heroin/morphine deaths have increased from about 10% in 1991 to about 40% in 1997. Forty-four percent of the fatal poisonings in Finland were caused by other group I drugs, mainly codeine and propoxyphene. The two fatal poisonings in Iceland were caused by carbon monoxide. Only few deaths in this investigation were caused by amphetamine and cocaine. A widespread use of alcohol, cannabis and benzodiazepines, especially diazepam, was seen in all the countries. © 2001 Elsevier Science Ireland Ltd. All rights reserved.

- Background and purpose — We have previously shown that specific exercises reduced the need for surgery in subacromial painpatients at 1-year follow-up. We have now investigated whetherthis result was maintained after 5 years and compared the outcomesof surgery and non-surgical treatment.Patients and methods — 97 patients were included in the previouslyreported randomized study of patients on a waiting list forsurgery. These patients were randomized to specifi c or unspecifi cexercises. After 3 months of exercises the patients were asked ifthey still wanted surgery and this was also assessed at the present5-year follow-up. The 1-year assessment included Constant–Murley score, DASH, VAS at night, rest and activity, EQ-5D, andEQ-VAS. All these outcome assessments were repeated after 5years in 91 of the patients.Results — At the 5-year follow-up more patients in the specifi cexercise group had declined surgery, 33 of 47 as compared with16 of 44 (p = 0.001) in the unspecifi c exercise group. The meanConstant–Murley score continued to improve between the 1- and5-year follow-ups in both surgically and non-surgically treatedgroups. On a group level there was no clinically relevant changebetween 1 and 5 years in any of the other outcome measuresregardless of treatment.Interpretation — This 5-year follow-up of a previously publishedrandomized controlled trial found that specifi c exercisesreduced the need for surgery in patients with subacromial pain.Patients not responding to specifi c exercises may achieve similargood results with surgery. These fi ndings emphasize that a specifi cexercise program may serve as a selection tool for surgery.

- Objective: The aim of this randomized controlled trial was to investigate the effect of an Internet-delivered cognitive behaviour therapy (iCBT), which incorporated emotion-regulation and conflict-resolution techniques, on intimate partner violence (IPV). Another aim was to test the theoretical underpinnings of the treatment model using mediation analysis.Method: Sixty-five participants with aggression problems in intimate adult relationships were recruited from the community and were randomly assigned to iCBT or to a monitored waitlist control. Participants were assessed with standardized self-report measures of IPV or aggression (Multidimensional Measure of Emotional Abuse, Revised Conflict Tactics Scale, and Aggression Questionnaire), relationship quality (Dyadic Adjustment Scale), anxiety or depression symptomatology (Patient Health Questionnaire; Generalized Anxiety Disorder Screener), at pretreatment, posttreatment (8weeks), and 1-year follow-up. Process variables (subscales of Dysfunctional and Emotional Regulation Scale and Anger Rumination Scale) were assessed weekly over the active treatment phase.Results: Robust linear regression analysis of all randomized participants showed significant treatment effects on emotional abuse relative to control at postassessment. Mediation analysis using growth curve modeling revealed that the treatment effect was partially mediated by changes in emotion-regulation ability. Controlled effects on secondary outcomes were also observed. Analyses of uncontrolled effects indicted that gains on IPV were maintained at 1-year follow-up.Conclusions: iCBT focusing on enhancing conflict-resolution skills and emotion-regulation ability has the potential to reduce IPV among self-recruited individuals with mild forms of abusive behaviour in intimate relationships. Emotion-regulation ability is potentially a key therapeutic process of change.Key Practitioner Message:Internet-delivered clinician-guided cognitive behaviour therapy is a viable treatment option for reducing intimate partner violence among self-recruited individuals with mild forms of abusive behaviour.For persons who display patterns of frequent and severe violence, other treatments are most likely needed.Emotion-regulation training is potentially a key therapeutic component that ought to be incorporated in interventions targeting IPV.

- Glutaredoxin is generally a glutathione-dependent hydrogen donor for ribonucleotide reductase and also catalyses general glutathione (GSH)-disulfide-oxidoreduction reactions in the presence of NADPH and glutathione reductase. A Glutaredoxin from human placenta was purified to homogeneity, as judged by SDS/PAGE and IEF (12 kDa). Purification was monitored by the activity with hydroxyethyl disulfide as a substrate. Values of pI for glutaredoxin were obtained by IEF; the pI of the protein shifted from 7.3 in its fully reduced state to 9.0 in the oxidized state after treatment with excess hydroxyethyl disulfide. The glutaredoxin preparation showed GSH-dependent hydrogen-donor activity with recombinant mouse ribonucleotide reductase, it exhibited dehydroascorbate reductase activity as well as hydroxyethyl-disulfide-reducing activity. The amino acid sequence (residues 3-104) of glutaredoxin was determined by peptide sequencing and residues 1, 2 and 105 by cDNA sequence analysis. The glutaredoxin sequence comprised the classical active site for glutaredoxins -Cys22-Pro-Tyr-Cys25- and three additional half-cystine residues; two of these in positions 78 and 82. The sequence was similar to other known mammalian glutaredoxins (about 80% identities), with important differences such as one additional Cys residue (Cys7) and no Met residue. The sequence of human glutaredoxin was compared to that of Escherichia coli glutaredoxin with known three-dimensional structure in solution to identify conserved residues and predict a structure from alignment. In particular the GSH-binding site of glutaredoxin was conserved between all molecules. A cDNA that encodes the entire glutaredoxin gene (grx) and flanking sequences was isolated from a human spleen cDNA library. The nucleotide sequence of this cDNA (0.8 kb) was determined, including the complete grx gene.

- The present study from 2002 includes medicolegally examined fatal poisonings among drug addicts in the five Nordic countries: Denmark, Finland, Iceland, Norway and Sweden. A common definition "drug addict" is applied by the participating countries. The number of deaths, age, sex, place of death, main intoxicant and other drugs present in the blood are recorded in order to obtain national data, as well as comparable Nordic data and data comparable to earlier studies from 1997 and 1991. The Icelandic results are commented on separately due to the low number of cases The most fatal overdoses are seen in Norway, in both the death rate (number per 100,000 inhabitants = 8.44) and in absolute number (n = 232). The comparable figures for the other four countries are Denmark 5.43 (n = 175), Iceland 3.6 (n = 6), Finland 2.93 (n = 94) and Sweden 2.56 (n = 136). In earlier studies from 1991 and 1997, the highest death rate is seen in Denmark, with Norway as number two. Denmark is the only country where the death rate decreases from 1997 to 2002. A relatively large increase in deaths in the younger age groups(less than 30 years) is noted from 1997 to 2002, except in Denmark, where only a small increase in overdose deaths in very young people (15-19 years) is observed. Females account for 12-20% of the overdoses (three out of six deaths in Iceland). Relatively fewer deaths are recorded in the capital areas in 2002 than in 1997 and 199 1, suggesting more geographically widespread drug use in the Nordic countries Heroin/morphine is the single most frequently encountered main intoxicant, varying from 10% of the cases in Finland to 72% of the cases in Norway. Finland differs from the other countries in that a high percentage of the fatal overdoses in Finland are not caused by an illicit drug; buprenorphine, overdoses are seen, and relatively few deaths resulting from heroin are seen. Methadone is the main intoxicant in 41% of the Danish overdose cases, 15% of the Norwegian cases, 4% of the Swedish cases and none of the Finnish overdose cases, an observation probably linked to different national prescription rules for methadone The analytical screening reveals extended polydrug use. Frequently seen substances, in addition to the main intoxicant are amphetamine, tetrahydrocannabinol (THC), benzodiazepines and ethanol.

- Background & Aims: Crohn's disease (CD) is associated with a disturbed intestinal barrier. Permeability studies have focused on inert molecules, but little is known about transepithelial transport of macromolecules with antigenic potential in humans. The aim of this study was to quantify permeation and to characterize passage routes for macromolecules in ileal mucosa in CD.Methods: Noninflamed and inflamed ileal mucosa specimens from patients with CD (n = 12) and ileal specimens from patients with colon cancer (n = 7) were studied regarding transmucosal permeation of ovalbumin, dextran (mol wt, 40,000), and 51Cr-EDTA for 90 minutes in vitro in Ussing chambers. Transepithelial passage routes for fluorescent ovalbumin and dextran 40,000 were investigated by confocal microscopy.Results: Noninflamed ileum from CD patients showed increased permeation of ovalbumin compared with ileum from colon cancer patients (P < 0.05). Dextran permeation was equal in the three groups, whereas 51Cr-EDTA permeability was increased in inflamed ileum. Ovalbumin passed both transcellularly and paracellularly, but dextran followed a strictly paracellular route. Both markers were subsequently endocytosed by cells of the lamina propria.Conclusions: Noninflamed ileal mucosa from patients with CD shows increased epithelial permeability to ovalbumin, probably by augmented transcytosis. This increase in antigen load to the lamina propria could be an initiating pathogenic event in CD.
