DRD3, but not COMT or DRD2, genotype affects executive functions in healthy and first-episode psychosis adolescents.
Catechol-O-methyltransferase (COMT) and dopamine receptors 2 (DRD2) and 3 (DRD3) have been associated with a higher risk of developing psychosis and with dopaminergic system (DAS) regulation. Frontal cognitive functioning has been proven to be a useful endophenotype for psychosis and it is partially controlled by the DAS. Val158Met (rs4680, COMT), Taq IA (rs1800497, DRD2) and Ser9Gly (rs6280; DRD3) polymorphisms were analyzed in a sample of 84 adolescent Caucasian patients with first-episode psychosis (ages 11-17) and 85 healthy Caucasian controls (ages 10-17). ⋯ The DRD3 Ser9Gly polymorphism seems to be involved with prefrontal cognition. This effect seems to be heterogeneous in terms of cognitive paradigms. The lack of association between COMT and DRD2 genotypes and cognition in our sample may be partially explained by the young age of the sample and the clinical heterogeneity of the patients.

Putative role of the COMT gene polymorphism (Val158Met) on verbal working memory functioning in a healthy population.
Working memory has been described as a neurocognitive probe of prefrontal brain functioning. Genetic variability related with catechol-O-methyltransferase (COMT) gene (Val158Met polymorphism) has received increasing attention as a possible modulator of working memory tasks in both schizophrenic patients and healthy subjects, although inconsistencies across studies have been found. This may be related to the existence of different working memory components, processes and modalities, which may have different sensitivities to subtle changes in dopamine levels and, therefore, the effect of the underlying COMT Val158Met genetic variability. ⋯ Moreover, the analysis for linear trend found that Met allele carriers showed significantly better performance than Val/Val individuals (B = 0.58 P = 0.031), although evidence for a linear trend was not found. None of the WCST indices differed among genotypes. Consistent with the hypothesis that Val158Met polymorphism (COMT gene) might account for individual differences on dopamine-dependent prefrontally related neurocognitive functions, the Letter-Number Sequencing task, which requires not only maintenance but also active manipulation of information seemed to be more sensitive to the disadvantageous Val/Val genotype in a large non-clinical sample.

We examined trends in delivery of mental health and substance abuse services at the nation's community health centers. ⋯ Community health centers are playing an increasingly central role in providing mental health/substance abuse treatment services in the United States. It is critical both to ensure that these centers have adequate resources for providing mental health/substance abuse care and that they develop effective linkages with mental health/substance abuse clinicians in the communities they serve.

Use of health-related quality-of-life assessments in daily clinical oncology nursing practice: a community hospital-based intervention study.
The current study evaluated the efficacy of incorporating standardized health-related quality of life (HRQL) assessments as a routine part of the outpatient chemotherapy treatment of cancer patients in a community hospital in terms of: 1) facilitating nurse-patient communication, 2) increasing nurses' awareness of patients' HRQL, 3) patient management, 4) patients' satisfaction, and 5) patients' HRQL. ⋯ Incorporating standardized HRQL assessments in daily clinical oncology nursing practice primarily facilitates the discussion of HRQL issues and increases nurses' awareness. Additional efforts are needed to enhance the effect of routine HRQL assessments on patient management and HRQL.

Improving Access to Essential Medicines: How Health Concerns can be Prioritised in the Global Governance System.
This paper discusses the politics of access to essential medicines and identifies 'space' in the current system where health concerns can be strengthened relative to trade. This issue is addressed from a global governance perspective focusing on the main actors who can have the greatest impact. ⋯ The collaboration has been so powerful due to the assistance of the media as well as the decision to compromise with pharmaceutical companies and their host countries. To improve access to essential medicines, six C's are needed: coalitions, civil society, citizenship, compromise, communication and collaboration.
