Patients with substance use and personality disorders: a comparison of patient characteristics, treatment process, and outcomes in Swiss and U.S. substance use disorder programs

Cross-cultural comparisons may increase our understanding of different models of substance use treatment and help identify consistent associations between patients' characteristics, treatment conditions, and outcomes.

Moving beyond a descriptive aquatic toxicology: the value of biological process and trait information

In order to improve the ability to link chemical exposure to toxicological and ecological effects, aquatic toxicology will have to move from observing what chemical concentrations induce adverse effects to more explanatory approaches, that are concepts which build on knowledge of biological processes and pathways leading from exposure to adverse effects, as well as on knowledge on stressor vulnerability as given by the genetic, physiological and ecological (e.g., life history) traits of biota. Developing aquatic toxicology in this direction faces a number of challenges, including (i) taking into account species differences in toxicant responses on the basis of the evolutionarily developed diversity of phenotypic vulnerability to environmental stressors, (ii) utilizing diversified biological response profiles to serve as biological read across for prioritizing chemicals, categorizing them according to modes of action, and for guiding targeted toxicity evaluation; (iii) prediction of ecological consequences of toxic exposure from knowledge of how biological processes and phenotypic traits lead to effect propagation across the levels of biological hierarchy; and (iv) the search for concepts to assess the cumulative impact of multiple stressors. An underlying theme in these challenges is that, in addition to the question of what the chemical does to the biological receptor, we should give increasing emphasis to the question how the biological receptor handles the chemicals, i.e., through which pathways the initial chemical-biological interaction extends to the adverse effects, how this extension is modulated by adaptive or compensatory processes as well as by phenotypic traits of the biological receptor.

[The model project "newborn auditory screening" in the Upper Palatinate: high process and result quality of an interdisciplinary concept]

BACKGROUND: In May 2003, a newborn auditory screening program was initiated in the Upper Palatinate. METHODS: Sequential OAE- and BERA-screening was conducted in all hospitals with obstetric facilities. The Screening Center at the Public Health Authority was responsible for the coordination of the screening process, completeness of participation, the follow-up of all subjects with a positive screening test and the quality of instrumental screening. RESULTS: A total of 96% of 17,469 newborns were screened. The referral rate at discharge was 1.6% (0.4% for bilateral positive findings). For 97% of the positive screening results, a definite diagnosis to confirm or exclude hearing loss was achieved; for 43% only after intervention by the Screening Center. Fifteen children with profound bilateral hearing impairment were identified of whom eight were only detected by the intervention of the Screening Center. CONCLUSION: The effective structures established in the Upper Palatinate provide a standard for the quality of neonatal auditory screening achievable in Germany.

[Integration process and organ-related fantasies in patients undergoing organ transplantation]

This review deals with an important aspect of organ transplantation, namely the process of psychic organ integration and organ-related fantasies. The body schema and body self are two important concepts in the integration of a transplanted organ. Different models and theories on organ integration are presented and will be discussed. There is evidence that beside the emotional impact and the influence on well-being, organ integration depends closely on psychic processes involving in the incorporation of the transplanted organ and the respective organ-related fantasies. Therefore, these organ fantasies - whether unconscious or conscious - may play an important role in the future development of the instinctive and highly individual relation the patients elaborate with the new organ. Beside the concern with the new organ, a bereavement to the lost old and sick organ may also influence the patients thoughts. Moreover, the good resolving of all these issues evokes the "good practice" patients develop towards the new situation. This will bring up issues as compliance, infections, rejection episodes and - most important - also organ survival.

Political process and government growth: a theoretical and empirical investigation

A striking feature of virtually al western industrialized countries sice the middle of the past century has been the persistent growth of their government sector. From the beginning of the century to the late 1970's, the government expenditures' share of gross national product has increased from 7% to 36% in the U.S., 11% to 40% in the U.K., and 3% to 25% in Japan. In Germany, it went from 7% to 42% (1872-1978), while in France it soared from 11% to 59% (1872-1979). The evolution of the number of government employees followed a similar pattern. In the U.S., for instance, the average annual rate of growth of the government labor force over the period 1899-1974 has been 3.17%, compared to a 1.62% average annual growth rate of the working population. Less quantifiable aspects like the number and scope of regulations also refelct a growing public sector.
