Translation and Adaptation of the Online Gambling Disorder Questionnaire into Brazilian Portuguese: Psychometric Validation

This study translated and adapted the Online Gambling Disorder Questionnaire (OGD-Q) for Brazilian Portuguese, examining its psychometric properties across 298 participants. The instrument demonstrated strong internal consistency (Cronbach's alpha 0.92) and significant correlations with depression, anxiety, stress, and online gaming behavior, supporting its validity as a screening tool for problematic online gambling.

Clinical Utility of Phosphatidylethanol Testing in Kidney Transplant Candidates

This retrospective study evaluated the clinical application of PEth, a blood biomarker detecting alcohol use in the prior 28 days, across 2,472 kidney transplant candidates at three medical centers (2020-2024). Among participants, 9.4% tested positive for PEth, with most indicating moderate alcohol consumption, informing transplant candidacy decisions and substance use disorder management.

Gambling Disorder in Couple Relationships: A Systematic Review of Evidence and Therapeutic Implications

This systematic review synthesizes 30 peer-reviewed studies on gambling disorder (GD) within couple relationships, examining its behavioral addiction features (craving, tolerance, withdrawal) and complex etiology. Research highlights how dysfunctional relational dynamics perpetuate GD, with studies documenting impacts on partners, links to domestic violence, and bidirectional relationships between couple dynamics and gambling behaviors.

Neural Correlates of Reward Learning and Extinction in Internet Gaming Disorder

This neuroimaging study compared brain activation patterns during reward conditioning and extinction learning between 25 individuals with internet gaming disorder, 23 at-risk gamers, and 35 controls. Findings show that problematic gamers display reduced sensitivity to non-gaming rewards in reward-processing brain regions and show altered extinction learning patterns, supporting the hypothesis that gaming disorder shares neurobiological mechanisms with substance addictions.
