Caught in the Psychiatric Net: Meanings and Experiences of ADHD,Pediatric Bipolar Disorder and Mental Health Treatment Among a Diverse Group of Families in the United States

Based on a 13-month ethnographic meaning-centered study of the lived experience of behavioral and emotional disorders among children and families living in the United States, this article highlights the range of orientations to mental health problems and treatment among families from diverse backgrounds. Detailed case portraits of three families are presented to illustrate the various meanings that psychiatric diagnoses and mental health treatments take on within families, with medicalized perspectives holding less salience among African-American families relative to Euro-Americans in the study. The diverse orientations to problems among families in the study suggest that, despite the dominance of biochemical and neurological explanations for behavioral and emotional distress in contemporary U.S. culture, and especially U.S. psychiatry, nonpathological interpretations have not been wholly eclipsed by broad trends toward biologization and medicalization. Families’ experiences are positioned to reveal the allure, as well as the limitations, of biopsychiatric approaches to behavioral and emotional problems.

A decade of marketing approval of gene and cell-based therapies in the United States,European Union and Japan: An evaluation of regulatory decision-making

There is a widely held expectation of clinical advance with the development of gene and cell-based therapies (GCTs). Yet, establishing benefits and risks is highly uncertain. We examine differences in decision-making for GCT approval between jurisdictions by comparing regulatory assessment procedures in the United States (US), European Union (EU) and Japan. A cohort of 18 assessment procedures was analyzed by comparing product characteristics, evidentiary and non-evidentiary factors considered for approval and post-marketing risk management. Product characteristics are very heterogeneous and only three products are marketed in multiple jurisdictions. Almost half of all approved GCTs received an orphan designation. Overall, confirmatory evidence or indications of clinical benefit were evident in US and EU applications, whereas in Japan approval was solely granted based on non-confirmatory evidence. Due to scientific uncertainties and safety risks, substantial post-marketing risk management activities were requested in the EU and Japan. EU and Japanese authorities often took unmet medical needs into consideration in decision-making for approval. These observations underline the effects of implemented legislation in these two jurisdictions that facilitate an adaptive approach to licensing. In the US, the recent assessments of two chimeric antigen receptor-T cell (CAR-T) products are suggestive of a trend toward a more permissive approach for GCT approval under recent reforms, in contrast to a more binary decision-making approach for previous approvals. It indicates that all three regulatory agencies are currently willing to take risks by approving GCTs with scientific uncertainties and safety risks, urging them to pay accurate attention to post-marketing risk management.     

Norms in the politics of housing for minorities: Evidence from a French,a German and a US metropolitan area

Throughout Western societies, policy‐makers who address the problems of disadvantaged ethnic and immigrant minorities confront norms that prescribe equal or preferential treatment for these groups. Variations in these norms make significant differences in policy‐making. Based on evidence from housing and planning policies and a standardized survey of local élites in comparable German, French and US metropolitan areas, this article analyses how these norms altered logics of policy‐making. Normative differences help to explain why policies to house minorities proved more successful in the German setting than in the French. Contrasts in central‐local relations, in local government, in political parties and in the social and economic background of policy‐making fail to account for the difference that these norms make. In the American setting normative ambiguities combined with institutional, social and spatial differences to render parallel norms comparatively ineffective.     

Consequences of the Ban of By-Products from Terrestrial Animals in Livestock Feeding in Germany and The European Union: Alternatives,Nutrient and Energy Cycles,Plant Production,and Economic Aspects

Consequences of the ban of meat and bone meal (MBM) and animal fat with regard to livestock feeding, cropping, ecology and economy where investigated with an inter-disciplinary approach for Germany and the European Union. Calculations were made for different production systems with pigs and poultry on the basis of statistical data for the production and for the feed markets as well as from requirement data for the respective species and production system. (1.) The ban of MBM from feeding caused a need for alternative protein sources. If all the amount of protein from MBM is to be replaced by soybean meal, in Germany and the EU about 0.30 and 2.30 · 10⁶t would be needed each year (supplementary amino acids not considered). Alternatively, doubling the grain legume acreage in Germany to about 420,000ha would supply a similar amount of protein. A wider application of phase feeding with adjusted dietary amino acid concentrations, however, would allow for saving protein to an extent which is similar to the amount of protein that was contributed by MBM in recent years. Thus, the ban is a minor problem in terms of ensuring amino acid supply. (2.) However, alternative plant ingredients cannot compensate for the gap in P supply that is caused by the ban. An additional demand for inorganic feed phosphates of about 14,000 and 110,000t per year is given in Germany and the EU, respectively. So far, this gap is filled almost completely by increased mining of rock phosphates. Alternatively, a general application of microbial phytase to all diets would largely fill this gap. Until the ban, MBM contributed to 57% of the supplementation of P that was needed for pigs and poultry. The ban of MBM makes large amounts of P irreversibly disappearing from the food chain. (3.) Energy from slaughter offal and cadavers can be utilized in different technologies, in the course of which the efficiency of energy utilisation depends on the technology applied. It is efficient in the cement work or rotation furnace if heat is the main energy required. In contrast, the energetic efficiency of fermentation is low. (4.) Incineration or co-incineration of MBM and other by-products causes pollution gas emissions amounting to about 1.4kg CO₂ and 0.2kg NO_x per kg. The CO₂ production as such is hardly disadvantageous, because heat and electrical energy can be generated by the combustion process. The prevention of dangerous gaseous emissions from MBM burning is current standard in the incineration plants in Germany and does not affect the environment inadmissibly. (5.) The effects of the MBM ban on the price for compound feed is not very significant. Obviously, substitution possibilities between different feed ingredients helped to exchange MBM without large price distortions. However, with each kg MBM not used in pig and poultry feeding economic losses of about 0.14¢ have to considered. In conclusion, the by far highest proportion of raw materials for MBM comes as by-products from the slaughter process. Coming this way, and assuring that further treatment is safe from the hygienic point of view, MBM and animal fat can be regarded as valuable sources of amino acids, minerals and energy in feeding pigs and poultry. Using them as feedstuffs could considerably contribute to the goal of keeping limited nutrients, phosphorus in particular, within the nutrient cycle and dealing responsible with limited resources.     

Toxoplasma gondii: effects of neuwiedase, a metalloproteinase from Bothrops neuwiedi snake venom, on the invasion and replication of human fibroblasts in vitro

The major aim to the present study was to determine the effects of neuwiedase, a metalloproteinase isolated from Bothrops neuwiedi snake venom, on invasion and replication of Toxoplasma gondii in human fibroblasts in vitro. Neuwiedase treatment was done on host cells previously infected with T. gondii or on parasite before fibroblast infection. When treatments were done after or before infection, infection rates were inhibited in 71% and 61%, respectively. Considering that therapy protocols currently used in T. gondii infection cause considerable side effects, particularly in immunocompromised individuals and pregnant women, the results of neuwiedase treatment described herein could be taken into account for the development of new synthetic therapeutic agents, mainly due to the capacity of this enzyme to degrade extracellular matrix components, such as laminin, fibronectin and type I collagen, which is important to interfere in T. gondii host cell invasion.     

Host range validation,molecular identification and release and establishment of a Chinese biotype of the Asian leaf beetle Lilioceris cheni (Coleoptera: Chrysomelidae: Criocerinae) for control of Dioscorea bulbifera L. in the southern United States

Dioscorea bulbifera, an Asian vine, is invasive in the southeastern USA. It rarely flowers but propagates from potato-like bulbils formed in leaf axils, which persist into the subsequent growing season. Lilioceris cheni Gressitt and Kimoto, a foliage-feeding beetle (Coleoptera: Chrysomelidae: Criocerinae) from Nepal, had been tested, proven to be a specialist and approved for release as a biological control agent. Regulatory delays, however, resulted in the demise of quarantine-held colonies, and acquisition of new Nepalese stock proved untenable. Searches then undertaken in southern China resulted in the collection of over 300 similar beetles. Two Chinese Lilioceris species were identified: one confirmed to be L. cheni and the other identified as Lilioceris egena (Weise). Mitochondrial analysis revealed an exact DNA match between some Chinese and one of the two Nepalese c oxidase subunit I haplotypes and all Chinese L. cheni haplotypes clustered as a single species but the comingling of the two species aroused concerns over possible hybridisation. These concerns were allayed by nuclear D2 analysis showing the absence of dual parental sequences. Nonetheless, diligence was exercised to ensure that the Chinese strains were safe to release. Abridged host testing using critical test species verified specificity. Caged releases during autumn 2011 documented the ability of adult beetles to overwinter in south Florida despite a prolonged lack of foliage. Open releases the following year produced vigorous populations that caused extensive defoliation. Preliminary observations indicate that L. cheni now contributes to the control of D. bulbifera and the bulbil-feeding L. egena should complement these effects if its host range proves appropriate.

Structural comparison in solution of a native and retro peptide derived from the third helix of Staphylococcus aureus protein A,domain B: retro peptides,a useful tool for the discrimination of helix stabilization factors dependent on the peptide chain orientation

A peptide fragment corresponding to the third helix of Staphylococcus Aureus protein A, domain B, was chosen to study the effect of the main‒chain direction upon secondary structure formation and stability, applying the retro‒enantio concept. For this purpose, two peptides consisting of the native (Ln) and reversed (Lr) sequences were synthesized and their conformational preferences analysed by CD and NMR spectroscopy. A combination of CD and NMR data, such as molar ellipcitity, NOE connectivities, Hα and NH chemical shifts, ³J_αN coupling constants and amide temperature coefficients indicated the presence of nascent helices for both Ln and Lr in water, stabilized upon addition of the fluorinated solvents TFE and HFIP. Helix formation and stabilization appeared to be very similar in both normal and retro peptides, despite the unfavourable charge–macrodipole interactions and bad N-capping in the retro peptide. Thus, these helix stabilization factors are not a secondary structure as determined for this specific peptide. In general, the synthesis and confirmational analysis of peptide pairs with opposite main‒chain directions, normal and retro peptides, could be useful in the determination of secondary structure stabilization factors dependent on the direction. © 1997 European Peptide Society and John Wiley & Sons, Ltd.
