Anhedonia—defined for participants in this study as diminished interest, motivation, or ability to experience pleasure in daily activities—is a core symptom required for diagnosis of MDD and may persist despite treatment. Limited awareness and shared understanding of anhedonia between patients and healthcare professionals (HCPs) may complicate communication during clinical encounters, highlighting an ongoing need to better characterize how this symptom is recognized and discussed in clinical practice. METHODS: This Johnson & Johnson (J&J) Patient Engagement Research Council (PERC) focus group study explored patient perspectives on conversations with HCPs about anhedonia and perceived barriers to these discussions. Four focus group sessions were conducted virtually in Nov-Dec 2023, with n = 12 adult patients with moderate-to-severe MDD in the US, using a semi-structured discussion guide to stimulate discussion and patient feedback. RESULTS: Across discussions, participants reported that conversations about anhedonia were more commonly initiated by patients (n = 8/12) than by HCPs (n = 7/12 reporting that HCPs rarely or never initiated such discussions). Participants also reported that treatment options specifically addressing anhedonia were infrequently discussed (n = 9/12). Perceived barriers to effective communication included time-constrained appointments, uncertainty or limited awareness of anhedonia, and discouragement related to prior ineffective treatment experiences. Participant-derived recommendations focused on the potential value of patient and HCP education, including educational materials for patients and HCPs, proactive screening protocols or structured prompts to facilitate discussion, and regular follow-up visits to revisit symptoms over time. CONCLUSIONS: These findings from a small, purposive sample suggest that challenges in discussing anhedonia during clinical visits may contribute to its limited consideration in ongoing care, underscoring the need for approaches that better support recognition and dialogue around this multifaceted symptom within routine clinical practice. </p>","PeriodicalId":7942,"journal":{"name":"Annals of General Psychiatry","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13274192/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147760150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elevated levels of psychological distress, depression, and suicidality, as well as major barriers to accessing care, have been widely reported. Although structural determinants such as poverty, discrimination, and restricted access to healthcare are increasingly acknowledged, the role of social and symbolic representations in shaping mental health research and clinical practice remains insufficiently explored. MAIN BODY: In this commentary, we argue that artistic and cultural practices provide a valuable and underutilised lens for understanding and addressing mental health inequities affecting Roma communities. Through examples drawn from Roma visual arts, exhibitions, and literary traditions, we illustrate how art can challenge deficit-based narratives and reshape the emotional and symbolic frameworks through which Roma lives are perceived. These shifts in representation have implications for clinical encounters, trust in services, and recognition of mental health needs. Beyond public visibility, we propose that arts-based and narrative approaches can also function as methodological resources within mental health research. By foregrounding lived experience, meaning-making, and relational dimensions of health that are often overlooked by conventional quantitative approaches, these methods can support more inclusive and participatory forms of knowledge production. When developed in partnership with Roma communities, such approaches may reduce epistemic distance, challenge dominant research categories, and improve the cultural relevance of mental health interventions. CONCLUSION: Reducing mental health inequities among Roma and Traveller populations requires approaches that extend beyond documenting disparities. Integrating artistic and narrative perspectives into research design and dissemination may help transform representations, strengthen community engagement, and support more equitable and responsive mental health care. </p>","PeriodicalId":7942,"journal":{"name":"Annals of General Psychiatry","volume":"25 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13109871/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147760170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This systematic review and meta-analysis aimed to clarify the impact of these interventions on mental health outcomes in adults. METHODS: A systematic search was conducted across PubMed, Scopus, and Web of Science databases until May 10, 2025, to identify randomized controlled trials (RCTs) evaluating the effects of pre-/pro-/synbiotics on depressive and anxiety symptoms in adults. Random-effects models were used to compute pooled standardized mean differences (SMDs) and 95% confidence intervals (CIs). Heterogeneity was assessed using the I2 statistic. Publication bias was evaluated using funnel plots and Egger’s test. RESULTS: A total of 70 RCTs (65 for depression and 49 for anxiety) met the inclusion criteria and had intervention durations ranging from 2 to 24 weeks. Pre-/pro-/synbiotics supplementation significantly reduced depressive symptoms (SMD = −0.57; 95% CI: −0.71, −0.43, p < 0.001; I2 = 83.0%) and anxiety symptoms (SMD = −0.43; 95% CI: −0.59, −0.28, p < 0.001; I2 = 80.5%). Subgroup analyses for depression revealed larger effects in studies with sample size < 50, and in participants aged ≥ 50 years. Probiotics and synbiotics significantly reduced depression, while prebiotics did not. All three intervention types significantly reduced anxiety, with synbiotics showing the largest effect. CONCLUSION: This meta-analysis suggests that supplementation with pre-/pro-/synbiotics may have beneficial effects on depressive and anxiety symptoms in adults. However, due to substantial heterogeneity and the overall moderate methodological quality of included studies, these findings should be interpreted with caution. Importantly, these interventions should be considered as an adjunctive option to support mental health, not as a replacement for standard evidence-based treatments such as pharmacotherapy and psychotherapy. Further high-quality RCTs with standardized protocols are warranted to confirm these findings and establish definitive clinical recommendations. </p>","PeriodicalId":7942,"journal":{"name":"Annals of General Psychiatry","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13224554/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147728071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All adult patients diagnosed with MDD according to the DSM-5-TR were invited to participate. Sampling was done through a convenient method. The Urdu-translated Antidepressant Side-Effect Checklist (U-ASEC) was developed through forward-back translation, expert panel review and pilot testing, and its psychometric properties such as internal consistency, construct validity were examined. Descriptive statistics were used to summarize demographic and clinical characteristics. Differences in adverse-effect scores across demographic and clinical groups were assessed with Kruskal-Wallis tests followed by Dunn's test with Bonferroni adjustment. Multivariable logistic regression models were fitted for each adverse-effect item to explore associations with antidepressant classes, adjusting for age, sex, tobacco use, comorbidity and duration of MDD.

Public health strategies to promote adolescents' mental well-being should focus on encouraging healthy screen behaviors and promoting sleep hygiene, particularly for E-type adolescents.</p>","PeriodicalId":7942,"journal":{"name":"Annals of General Psychiatry","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13195829/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147632108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
