Effect of an Online Intervention on Nursing Students' Alcohol Consumption and Social Support.

Objective: This research aimed to evaluate the impact of custom-developed software on nursing students' alcohol consumption and perception of social support.

Method: A quasi-experimental study was conducted with 88 students in the early years of nursing courses at a Brazilian public university. The members of the intervention group (n = 40) participated in a lecture delivered by a nurse and used online software developed based on cognitive behavioral techniques and social skills training.

Distance from a cultural model of substance use risk, internalization, and self-stigma in urban Brazil.

Introduction: A cognitive theory of culture as socially distributed cultural models has proven useful in research. Cultural models exist in two forms: the model shared by individuals in a social group, and individual versions of that model modified by personal experience. In previous research we documented a shared cultural model of substance use risk among a general population sample in urban Brazil.

Prevalence of malocclusion in early childhood and its associated factors in a primary care service in Brazil.

Purpose: to evaluate the prevalence of malocclusion and its associated factors of children cared for by a PHC Service in Porto Alegre, Brazil.

Methods: a cross-sectional study nested in a cohort, carried out in 12 Health Care Practices. Of the 414 children in the cohort examined, 268 were assessed for malocclusion.

Use of psychoactive substances in women in outpatient treatment.

Objective: to characterize the sociodemographic and psychiatric profile of women users of psychoactive substances in treatment for drug addiction.

Method: descriptive study of quantitative approach performed with women attended at a Psychosocial Care Center for Users of Alcohol and Other Drugs (CAPS ad) from the interior of São Paulo State.

Results: the sample consisted of 349 adult women, single, low educational level and unemployed, users of alcohol, cocaine, crack and tranquillizers.

High-throughput tool to discriminate effects of NMs (Cu-NPs, Cu-nanowires, CuNO, and Cu salt aged): transcriptomics in Enchytraeus crypticus.

The current testing of nanomaterials (NMs) via standard toxicity tests does not cover many of the NMs specificities. One of the recommendations lays on understanding the mechanisms of action, as these can help predicting long-term effects and safe-by-design production. In the present study, we used the high-throughput gene expression tool, developed for Enchytraeus crypticus (4 × 44k Agilent microarray), to study the effects of exposure to several copper (Cu) forms.

Molecular analysis of skin bacterial assemblages from codfish and pollock after dry-salted fish production.

Dry-salted codfish and pollock are commercially important food products with a relatively long shelf life. To date, bacterial assemblages present in these products that are relevant for food safety have been monitored using only classical molecular and/or cultivation methods. The present study employed a rapid and accurate identification method involving PCR with denaturing gradient gel electrophoresis and pyrosequencing to characterize the bacterial assemblages in the skin of three closely related fishes: Gadus morhua, Gadus macrocephalus, and Theragra chalcogramma.
