Correlates of Ecstasy use in the Swedish General Population.

The aim of the present study was to report independent correlates of ecstasy use in the Swedish general population. Data were drawn from a Swedish national household survey conducted in 2008-2009 on a random, stratified sample of 58,000 inhabitants of Sweden, aged 15 to 64. The response rate was 38.3%. Logistic regression analysis was used to identify correlates of recent (past-year) and former ecstasy use. Results are discussed and limitations of the study are noted

Risk factors for criminal recidivism - a prospective follow-up study in prisoners with substance abuse

Background: Substance use in general has been shown to predict criminal recidivism. The present study aimed to examine potential predictors of criminal recidivism, including substance-specific substance use patterns, in prisoners with substance use. Methods: A cohort of prisoners with substance use problems (N = 4,152) were assessed with the Addiction Severity Index (ASI) in the Swedish criminal justice system. Clients were followed for an average of 2.7 years. Criminal recidivism was defined as any return to the criminal justice system. Results: During follow-up, 69 percent (n = 2,862) returned to the criminal justice system. Recidivism was associated with amphetamine and heroin use, with an additive risk for injectors, and with polysubstance use. Also, recidivism was negatively associated with alcohol, other opioids than heroin/methadone and with hallucinogenic drugs, and positively associated with previous psychiatric in-patient treatment, violent behaviour, and with a shorter index sentence. Associations remained when controlling for type of crime. Conclusions: Even when controlling for type and severity of crime, and for psychiatric problems, risk of criminal relapse was increased by substance use variables, including amphetamine, heroin and polysubstance use, and an additional risk was shown for injection drug users. These findings have implications for the need for substance abuse treatment after release from prison

Nonmedical Prescription Drug Use (NMPDU) in the Swedish General Population-Correlates of Analgesic and Sedative Use.

Background: Nonmedical prescription drug use (NMPDU) is a growing problem in many countries. Objectives: The aim of the present study was to report correlates of and compare different subtypes of NMPDU in the Swedish general population. Methods: Data were drawn from a Swedish national household survey conducted in 2008-2009. A stratified sample of 58,000 individuals aged 15 to 64 was randomly selected, with a response rate of 38.3%. Hierarchical logistic regression analysis was used to compare sociodemographic, substance use, and health correlates of nonmedical analgesic use, nonmedical sedative use, and combined nonmedical use of these two types of prescription drugs. Results: In the final logistic regression model, all three patterns of NMPDU were equally associated with female gender, hazardous alcohol use, habitual smoking and cannabis use, but there were several significant differences in other demographic, health, and drug use correlates between the groups. Conclusions/Importance: Nonmedical use of prescription analgesics, prescription sedatives and combined nonmedical use of these drugs might constitute clinically distinct subgroups of NMPDU. This study is one of few to report correlates of NMPDU from a large, national household survey in a country other than the United States

Response of the Esophageal Epithelium to Concomitant Cis-Dichlorodiammineplatinum(II) and Radiation Treatment. An Electron Microscopic Study in Rabbits

The rabbit esophageal mucosa was irradiated with daily fractions of 2 Gy up to an accumulated dose of 20 Gy (total dose 2, 6, 10. 16 or 20 Gy). Fifteen to forty-five minutes before the start of each irradiation 0.3 mg Cis-dichlorodiammineplatinum (cis-DDP, cisplatinum) was given by intraperitoneal injection to each rabbit. Examinations were carried out 1-10 days after each fractionation schedule, when specimens were taken for morphological investigations. Scanning electron microscope (SEM) examination showed a gradual development of damage with cell loss and structural disarrangement of the microridges and whorls on the surface. However, with further treatment the esophageal mucosa exposed to cis-DDP and radiation normalized faster and more complete compared to the esophageal part exposed to cis-DDP alone. The difference may depend on an accelerated proliferation in the part of the trachea that is exposed to a combined treatment

The Response of the Tracheal Epithelium to Concomitant Cis-Diamminedichloroplatinum (II) and Radiation. An Electron Microscopic Study in Rabbits

The ciliated epithelium of the rabbit trachea was irradiated with daily fractions of 2 Gy up to an accumulated dose of 20 Gy (total dose: 2, 6, 10, 16, or 20 Gy). Fifteen to forty-five minutes before the start of each irradiation 0.3 mg Cis-diamminedichloroplatinum (cis-DDP) was given by intraperitoneal injection to each rabbit. Examinations were carried out 1-10 days after each fractionation schedule, when specimens were taken for morphological investigations. Scanning electron microscope (SEM) examination showed a gradual development of ciliary damage, from blebs on the cilia to swollen tips, broken and bent cilia and finally an epithelial injury with areas free from cilia, and a surface covered with microvilli-like structures. SEM also showed cell loss, and remnants of dead cells on the surface together with detritus. By transmission electron microscopy (TEM), ciliary damage, cell death and cell loss of the ciliated cell layer, as well as exfoliation of portions of goblet-like cells on the surface, could be confirmed. Scoring of SEM and TEM micro graphs showed that for the tracheal part treated with cis-DDP and radiation, the maximal damage was expressed in the dose group 10 Gy, and above this no further increase in the average reaction occurred. For the part of the trachea only exposed to cis-DDP, the damage increased with the dose. The difference observed speaks for an accelerated proliferation exerted by the radiation

Beroendevård i socialtjänst och sjukvård - En svensk modell att utmana.

Addiction treatment often requires medical, psychosocial and social expertise - and benefits from collaboration. The pronounced role of social authorities in evaluation and treatment is unique to the addiction field. Unified responsibility for evaluation and treatment of addiction is under consideration. Treatment of psychiatric and physical co-morbidity benefits from a unified responsibility within the hospital system

The Effect of Ionizing Irradiation on Type I Collagen of the Tail in Growing Mice: A Histology and Electron Microscopy Study

In order to examine the effect of radiation on growing tissue, especially the fibroblasts and their end-product, the collagen fibres, tails from 24 mice were irradiated at an age of 8 days with 20 Gy and 30 Gy (\u3e°Co). Tails from 18 animals served as controls. Six mice from each group were sacrificed on day 8, 20 and 30. Transmission electron microscopy was used to examine the fibroblasts and the collagen fibrils. Non-irradiated fibroblasts had a nucleus rich in chromatin and an abundant endoplasmic reticulum with cistemae and condensing vacuoles. On day 20, approximately 50 % , and on day 30, 25 % of the fibroblasts irradiated with 30 Gy had a sparse endoplasmic reticulum pointing to a reduction of protein synthesis. While, on day 20, the fibrils irradiated with 20 Gy and with 30 Gy had significantly larger diameters compared to the controls, on day 30, the irradiated fibrils had a notably smaller diameter compared to the controls; 30 Gy-fibrils were larger than the 20 Gy-fibrils on both days. On day 20, the binding mean value of the 30 Gy-fibrils exceeded that of the controls and was significantly higher than that of the 20 Gy-fibrils, which was lower, though not significantly, than the controls. On day 30, the banding mean value of the 30 Gy-fibrils was notably lower than the control; and the value of the 20 Gy-fibrils was significantly lower than that of the 30 Gy-fibrils. The results are explained as an edema together with an inhibitory effect on the protein synthesis of the fibroblasts caused by the irradiation. This deduction 1s further supported by light microscopy of the tails

Scanning Electron Microscopy of Human Esophageal Mucosa in Patients with Carcinoma of the Esophagus

Specimens taken at surgery from 15 patients with carcinoma of the esophagus were examined with scanning electron microscopy. Nine patients were treated with chemotherapy (cisplatin + 5-fluorouracil), surgery and radiotherapy; one received preoperative radiotherapy only; and the remaining five primary surgery only. Scanning electron microscopy was performed on specimens of both tumor tissue and the mucosa at least 5 cm from the tumor. In adjacent non-tumor tissue, damage due to treatment was observed in the form of changes in microridges and increased cell loss. In tumor tissue, the degree of damage was correlated to tumor response to treatment. For patients with no residual tumor after treatment, the ultrastructure was normalized with a low tumor score, while for patients with residual tumor, the score was high
