Objective: There is growing evidence supporting the association between migration and posttraumatic stress disorder (PTSD). Considering the growing population of migrants and the particularities of providing culturally sensitive mental health care for these persons, clinicians should be kept up to date with the latest information regarding this topic. The objective of this study was to critically review the literature regarding migration, trauma and PTSD, and mental health services. Methods: The PubMed, SciELO, LILACS, and ISI Web of Science databases were searched for articles published in Portuguese, English, Spanish, or French, and indexed from inception to 2017. The following keywords were used: migration, mental health, mental health services, stress, posttraumatic stress disorder, and trauma. Results: Migration is associated with specific stressors, mainly related to the migratory experience and to the necessary process of acculturation occurring in adaptation to the host country. These major stressors have potential consequences in many areas, including mental health. The prevalence of PTSD among migrants is very high (47%), especially among refugees, who experience it at nearly twice the rate of migrant workers. Conclusions: Mental health professionals must be trained to recognize and provide appropriate care for posttraumatic and/or stress-related disorders among migrants. [ABSTRACT FROM AUTHOR]

The putative role of gluten in the pathophysiology of severe mental illnesses remains uncertain and there is doubt about the possible benefit of gluten-free diets for individuals affected by psychosis and mood disorders. The objective of this review was to summarize the findings linking gluten related conditions to pathophysiological substrates implicated in schizophrenia and mood disorders and review the evidences of potential benefits of glute-free diets in these populations. A literature search was conducted within PubMed and Scielo databases including references from inception until March 1st 2017. The strategy search was to use the key words “gluten”, “celiac disease”, “wheat”, “bipolar disorder”, “mood disorders”, “psychosis”, “schizophrenia”, “depression”. In the review about the potential efficacy of gluten-free diets in severe mental illnesses, we included only studies with original data, including cross sectional and longitudinal studies and clinical trials. Book chapters, review articles and meta-analysis and republished data were excluded. Although the current available evidences suggest that people with celiac disease or gluten allergy could have a slightly higher risk of schizophrenia and mood disorders compared to the general population, the literature review reveals significant inaccuracies in the data. There is insufficient evidence to recommend gluten-free diets for populations with psychosis and mood disorders. [ABSTRACT FROM AUTHOR]
