Development of a modular ICF-based core set for the German substance use disorders treatment.

PURPOSE: We aimed to develop a modular Core Set based on the International Classification of Functioning, Disability and Health (ICF) for describing functioning in patients with substance use disorders (SUDs). To match the structure of the German health service system, the Core Set was split into modules for different service segments. METHODS: We followed a consensus process including several preparatory studies. To identify candidate ICF categories, we performed an ICF linking of guideline-recommended assessments, patient focus groups and patient and expert surveys. Categories were prioritized for different service segments and compiled into preliminary modules. The Core Set was tested in 13 treatment sites. Health professionals rated each category's relevance, and contents of the Modular ICF-based Core Set for SUDs (MCSS) were compared to patient-reported treatment goals. An advisory board decided on revisions to the MCSS. RESULTS: The MCSS consists of a basic module (25 categories) and five additional modules for these treatment segments: counselling (8), qualified withdrawal (6), orientation (7), rehabilitation (32), and social integration services (10). CONCLUSIONS: The MCSS provides a framework for harmonizing communication, documentation and interface management in German SUD health services. The basic module, consisting of 25 categories, can be employed as a Brief ICF Core Set.Implications for rehabilitationThe MCSS can serve as a standard for describing functioning in patients with SUDs in Germany, as well as harmonize communication and reporting of treatment relevant information.In clinical practice, the MCSS can be used for the structured assessment of psychosocial problems and participation restrictions, goal setting, and outcome evaluation.Although the MCSS was developed in Germany, its proximity to the themes frequently identified in the literature regarding SUDs internationally suggests that it may be of use in other countries as well.The basic module may be employed as a Brief ICF Core Set.

The German Mouse Clinic: a platform for systemic phenotype analysis of mouse models.

The German Mouse Clinic (GMC) is a large scale phenotyping center where mouse mutant lines are analyzed in a standardized and comprehensive way. The result is an almost complete picture of the phenotype of a mouse mutant line--a systemic view. At the GMC, expert scientists from various fields of mouse research work in close cooperation with clinicians side by side at one location. The phenotype screens comprise the following areas: allergy, behavior, clinical chemistry, cardiovascular analyses, dysmorphology, bone and cartilage, energy metabolism, eye and vision, host-pathogen interactions, immunology, lung function, molecular phenotyping, neurology, nociception, steroid metabolism, and pathology. The German Mouse Clinic is an open access platform that offers a collaboration-based phenotyping to the scientific community (www.mouseclinic.de). More than 80 mutant lines have been analyzed in a primary screen for 320 parameters, and for 95% of the mutant lines we have found new or additional phenotypes that were not associated with the mouse line before. Our data contributed to the association of mutant mouse lines to the corresponding human disease. In addition, the systemic phenotype analysis accounts for pleiotropic gene functions and refines previous phenotypic characterizations. This is an important basis for the analysis of underlying disease mechanisms. We are currently setting up a platform that will include environmental challenge tests to decipher genome-environmental interactions in the areas nutrition, exercise, air, stress and infection with different standardized experiments. This will help us to identify genetic predispositions as susceptibility factors for environmental influences.

Improved method for detection of methanotrophic bacteria in forest soils by PCR.

A primer set was designed for the specific detection of methanotrophic bacteria in forest soils by PCR. The primer sequences were derived from highly conservative regions of the pmoA gene, encoding the alpha-subunit of the particulate methane monooxygenase present in all methanotrophs. In control experiments with genomic DNA from a collection of different type I, II, and X methanotrophs, it could be demonstrated that the new primers were specific for members of the genera Methylosinus, Methylocystis, Methylomonas, Methylobacter, and Methylococcus. To test the suitability of the new primers for the detection of particulate methane monooxygenase (pMMO) containing methanotrophs in environmental samples we used DNA extracts from an acid spruce forest soil. For simple and rapid purification of the DNA extracts, the samples were separated by electrophoresis on a low-melting-point agarose gel. This allowed us to efficiently separate the DNA from coextracted humic acids. The DNA from the melted agarose gel was ready for use in PCR reactions. In PCR reactions with DNA from the Ah soil layer, products of the correct size were amplified by PCR by use of the new primers. By sequencing of cloned PCR products, it could be confirmed that the PCR products represented partial sequences with strong similarity to the pmoA gene. The sequence was most related to the pmoA sequence of a type II methanotroph strain isolated from the Ah layer of the investigated soils.

Evidence for the participation of a 5-oxo-prolinase in degradation of glutathione in Nicotiana tabacum.

During degradation of glutathione in tobacco suspension cultures substancial amounts of 5-oxo-proline are formed in vivo as well as in crude cell homogenates in vitro. The existance of a 5-oxo-prolinase that catalyzes the conversion of 5-oxo-proline to glutamic acid was demonstrated in tobacco cells, grown with glutathione as sole sulfur source.

Sodium content of community water supplies in California.

The amount of sodium ion in water used for ingestion may be critical in effective use of a low sodium dietary regimen. Waters containing not over 20 mg of sodium per liter are provided for in the sodium restricted diets set forth by the American Heart Association. For diets containing more than 500 mg of sodium a day, waters of greater sodium content may be used if proper dietary adjustments are made. While assessment of the long-term average sodium content of a community water supply is difficult, the determined values for sodium lend to classification within range categories. The larger community water supplies in California are presented within several range categories of sodium content. The more commonly used water softeners add sodium to water. The sodium-restricted patient should be cautioned against their use. Similar consideration should probably be given to water supplies of retirement communities where the potential for disorders requiring sodium restriction is greater than in the general population.
