Embarrassment when illness strikes a close relative: a World Mental Health Survey Consortium Multi-Site Study.

BACKGROUND: In this global study we sought to estimate the degree to which a family member might feel embarrassed when a close relative is suffering from an alcohol, drug, or mental health condition (ADMC) versus a general medical condition (GMC). To date, most studies have considered embarrassment and stigma in society and internalized by the afflicted individual but have not assessed family embarrassment in a large-scale study. METHOD: In 16 sites of the World Mental Health Surveys (WMHS), standardized assessments were completed including items on family embarrassment. Site matching was used to constrain local socially shared determinants of stigma-related feelings, enabling a conditional logistic regression model that estimates the embarrassment close relatives may hold in relation to family members affected by an ADMC, a GMC, or both conditions. RESULTS: There was a statistically robust association such that subgroups with an ADMC-affected relative were more likely to feel embarrassed compared to subgroups with a relative affected by a GMC (p<0.001), even with covariate adjustments for age and sex. CONCLUSIONS: . The pattern of evidence from this research is consistent with conceptual models for interventions that target individual- and family-level stigma-related feelings of embarrassment as possible obstacles to effective early intervention and treatment for an ADMC. Macro-level interventions are under way but micro-level interventions may also be required among family members, along with care for each person with an ADMC.

Effect of surfactants on PAH biodegradation by a bacterial consortium and on the dynamics of the bacterial community during the process.

The aim of this work was to evaluate the effect of a non-biodegradable (Tergitol NP-10) and a biodegradable (Tween-80) surfactant on growth, degradation rate and microbial dynamics of a polycyclic aromatic hydrocarbon (PAHs) degrading consortium (C2PL05) from a petroleum polluted soil, applying cultivable and non cultivable techniques. Growth and degradation rate were significantly lower with Tergitol NP-10 than that with Tween-80. Toxicity did not show any significant reduction with Tergitol NP-10 whereas with Tween-80 toxicity was almost depleted (30%) after 40 days. Regarding to the cultured bacteria, Pseudomonas and Stenotrophomonas groups were dominant during PAH degradation with Tergitol NP-10, whereas Enterobacter and Stenotrophomonas were dominant with Tween-80. DGGE analyses (PRIMER and MDS) showed that bacteria composition was more similar between treatments when PAHs were consumed than when PAHs concentration was still high. Community changes between treatments were a consequence of Pseudomonas sp., Sphingomonas sp., Sphingobium sp. and Agromonas sp.

Valoración psiquiátrica y legal de la epilepsia / Psychiatric and legal assessment of the epilepsy

Tradicionalmente, la epilepsia ha sido considerada como una enfermedad relacionada con problemas legales de todo tipo. En la actualidad, el estudio clínico de la misma se realiza, fundamentalmente, desde la Neurología y la Psiquiatría. En el trabajo se pretende realizar de una forma concreta aunque no extensa, una aproximación psiquiátrica al problema y poner en relación la psicopatología con la problemática legal que suscita (AU)

Analysis of phytochelatin-cadmium complexes from plant tissue culture using nano-electrospray ionization tandem mass spectrometry and capillary liquid chromatography/electrospray ionization tandem mass spectrometry.

Phytochelatins (PCs, also known as class III metallothioneins), a family of sulfhydryl-rich peptides with the formula (gamma-GluCys)(n)Gly(Pc(n), n = 2-11), are induced in plants, yeast and fungi exposed to heavy metals, and are thought to detoxify metals by forming PC- metal complexes. Although PCs have been detected, PC- metal complexes have not been well characterized. In this work, nano-electrospray ionization tandem mass spectrometry (nano-ESI-MS/MS) and capillary liquid chromatography/electrospray ionization tandem mass spectrometry (capillary LC/ESI-MS/MS) methods were used to analyze PC - Cd complexes isolated from Datura innoxia, also known as Jimsonweed, cell culture exposed to Cd. With nano-ESI-MS/MS and capillary LC/ESI-MS/MS we could simultaneously detect the presence of PCs and PC - Cd complexes from plant cell extracts, unambiguously identify these species and elucidate the nature of individual PC - Cd complexes. Phytochelatins with n = 3-6 were detected, as were PC - Cd complexes with PC(3), PC(4) and PC(5). This is the first study to report the size and nature of native PC - Cd complexes from plant tissue samples. These results demonstrate that the direct analysis of plant extracts using nano-ESI-MS/MS and capillary LC/ESI-MS/MS methods is simple and sensitive to the range of PCs and PC - Cd complexes in plants. Hence these methods open up new opportunities for further quantitative analysis of PCs and PC - metal complexes in cell culture and plant systems to understand the relationship between the biosynthesis of these compounds and metal tolerance.

Mexican geneticists' opinions on disclosure issues.

Here we discuss the opinion on disclosure issues (respect for confidentiality) of Mexican professionals working in clinical genetics. The information was obtained from a comprehensive survey on genetics, ethics and society organized by Wertz and Fletcher in 1993, in which geneticists from 37 nations participated. The responses to 18 questions from 64 of 89 (72%) geneticists invited to participate were analyzed for this paper. The questions were directed to investigate: a) disclosure of clinically relevant information in several situations such as testicular feminization syndrome, mosaic de novo balanced translocation in a fetus, or accidental discovery of non-paternity; b) the protection of patient's privacy from the spouse or blood relatives; and c) confidentiality in cases with high genetic risk to relatives. The results reveal significant disparity between general responses related to disclosure of all clinically relevant information and specific responses in particular cases. In addition, professionals appear to give higher priority to protecting the spouse, blood relatives or public safety, rather than the patient's confidentiality.
