This paper focuses on the evaluation of addiction program effectiveness which involves changes in health-related quality of life (HRQoL) profile. This study was conducted from 2007 until 2010 at a rural methadone maintenance treatment center in Malaysia to assess HRQoL outcomes before and after treatment. Fifty-seven respondents completed the WHOQOL-BREF at baseline, 6 months, and 12 months postintervention. Data were analyzed using nonparametric techniques (SPSS 15). Significant and positive HRQoL impacts were demonstrated. Future studies with larger sample are encouraged. This study was supported by the Ministry of Health Malaysia.

The Pego-Oliva Marsh is the second most important wetland in the Valencian Community (Spain). It is included in the RAMSAR agreement and represents one key point for migratory birds. Emerging contaminants from the human pressure, such as pharmaceuticals, illicit drugs and personal care product, are not included in the list of priority contaminants of the Water Framework Directive yet, and are neither monitored nor controlled. However, pollution of emerging contaminants can threaten the environment and even human health. In order to understand the status of the emerging contamination and recommend future rationalization of countermeasures, the occurrence of illicit drugs was investigated.Samples were collected at 23 sites from the main irrigation channels and the marsh. Illicit drugs were extracted using solid phase extraction and determined by liquid chromatography tandem mass spectrometry. The method detection limits ranged from 0.01 to 1.54 ng l(-1) and the recoveries from 57% to 120%.3,4-Methylenedioxymethamphetamine, ketamine, morphine, benzoylecgonine, cocaine, methadone, 6-acetylmorphine and nor-9-carboxy-tetrahydrocannabinol were detected. The mean concentrations were 0.62, 21.33, 1.30, 1.92, 2.25, 0.32, 0.04 and 0.07 ng l(-1), respectively. The highest concentrations were in the north of Pego-Oliva Marsh.The pollution status by illicit drugs of the Pego-Oliva Marsh has been established. However, contamination levels in all the area of the natural park were low compared with those reported in other superficial waters.

This is a study about balancing motherhood and drug addiction, during the transition to parenthood. Few studies have dealt with the parental experience of drug-addicted mothers. The participants included 24 drug-addicted mothers, on methadone, with ages 25-42 and with children 1-32 months of age. Semi-structured interviews were conducted and analyzed according to Grounded Theory. The mothers’ main concern was the ambivalence they felt towards pregnancy/motherhood and drug addiction, which was associated with strong feelings of guilt. Confronted with this ambivalence their maternal role becomes merely functional. They focus on providing the basic care to the child, but show little willingness to talk or play. Social support, especially from the partner seems to have a positive role.

New immediate release formulation for deterring abuse of methadone.

Context. Drug abusers are known to take a dosage form containing an opioid analgesic and crush, shear, grind, chew, or dissolve it in water or in alcohol, in order to extract the opioid component. Objective. Develop an anti abuse immediate release formulation using methadone as model drug. Materials and Methods. Tablets combining methadone and alkalizing agents were manufactured. A methadone assay was used to determine extraction efficiency from tablets in aqueous and alcohol solvents. In vitro dissolution testing was used to determine drug release in different media. Results and Discussions. Meglumine-based formulations prevented extraction of 70 to 100% of methadone from tablets. Addition of this alkalizing agent caused methadone to precipitate out of a solution along with other ingredients and be retained on standard filters. Meglumine-containing and control tablets showed similar dissolution profiles in acidic media, suggesting adequate solubilisation of the drug early in the gastrointestinal tract. Finally, stability upon storage of the formulations for 6 months at 25°C/60%RH and 40°C/75%RH was confirmed. Conclusion. Incorporation of an alkalizing agent into methadone tablets significantly reduced the preparation of a methadone solution for intravenous administration and abuse, while allowing the formulation to release methadone in gastric media and provide desired pharmacological effect.
