Definition and description of larval types of Cyaneolytta (Coleoptera Meloidae) and new records of their phoretic association with Carabidae (Coleoptera)

The hypothesis of a general phoretic association of Cyaneolytta Péringuey 1909 triungulins (Meloidae) with Anthiini (Carabidae) is supported by many new records from several regions of Africa and India. Four morphological larval types of Cyaneolytta are described and some morpho-species belonging to different morphotypes are identified and illustrated

Gamma-hydroxybutyrate (GHB) for prevention and treatment of alcohol withdrawal

This is the protocol for a review and there is no abstract. The objectives are as follows: To evaluate the efficacy and safety of GHB in prevention and treatment of the AWS, more specifically • to compare the efficacy of GHB with placebo or other drugs; • to identify the most effective GHB dosage and schedules; • to estimate the incidence of side effects; • to carry out a risk-benefit analysis

Opioid overdose risk during and after drug treatment for heroin dependence: An incidence density case–control study nested in the VEdeTTE cohort

Introduction and Aims: To corroborate protective effects of a range of drug treatment modalities against overdose mortality risk. Design and Methods: Nested case–control study, with incidence density sampling, selecting controls retrospectively at each case event. Cases and controls came from a sub-cohort of opioid-dependent patients (n = 4444) from two Italian regions (Lazio and Piedmont). From 1998 to 2005, there were 91 overdose deaths (cases) matched to 352 controls. The primary outcome was overdose mortality and the primary exposure was drug treatment: opioid agonist treatment (OAT), opioid detoxification, residential community, psychosocial and other pharmacological treatment. Conditional logistic regression models generated intervention effects comparing mortality risk in and out of treatment, adjusting for confounding variables. Results: Overall, drug treatment reduced overdose mortality risk by 80% [adjusted odds ratio (AOR) 0.18, 95% confidence interval (CI) 0.10–0.33, P < 0.001] compared to being out of treatment. There was a particularly strong protective effect of OAT on overdose mortality (AOR 0.08, 95% CI 0.03–0.23, P < 0.001) compared to being out of treatment. There was evidence of a substantially elevated risk of overdose in the first month of leaving treatment (AOR 23.50, 95% CI 7.84–70.19, P < 0.001) compared to being in treatment. Discussion and Conclusions: The nested case–control design strengthened earlier findings that OAT in Italy has strong protective effects on overdose mortality risk, much stronger than has been previously seen in other Western European settings

Psychopathology of addiction: May a SCL-90-based five dimensions structure be applied irrespectively of the involved drug?

BACKGROUND: We previously found a five cluster of psychological symptoms in heroin use disorder (HUD) patients: ‘worthlessness-being trapped’, ‘somatic-symptoms’, ‘sensitivity-psychoticism’, ‘panic-anxiety’, and ‘violence-suicide’. We demonstrated that this aggregation is independent of the chosen treatment, of intoxication status and of the presence of psychiatric problems. METHODS: 2314 Subjects, with alcohol, heroin or cocaine dependence were assigned to one of the five clusters. Differences between patients dependent on alcohol, heroin and cocaine in the frequency of the five clusters and in their severity were analysed. The association between the secondary abuse of alcohol and cocaine and the five clusters was also considered in the subsample of HUD patients. RESULTS: We confirmed a positive association of the ‘somatic symptoms’ dimension with the condition of heroin versus cocaine dependence and of the ‘sensitivity-psychoticism’ dimension with the condition of alcohol versus heroin dependence. ‘Somatic symptoms’ and ‘panic anxiety’ successfully discriminated between patients as being alcohol, heroin or cocaine dependents. Looking at the subsample of heroin dependents, no significant differences were observed. CONCLUSIONS: The available evidence coming from our results, taken as a whole, seems to support the extension of the psychopathological structure previously observed in opioid addicts to the population of alcohol and cocaine dependents
