Hence, conducting an updated study on suicide and homicide involving these weapons in Milan, Italy, during 2009–2022 was deemed appropriate. This study includes comparisons with a similar analysis spanning 1993–2008, allowing for a comprehensive exploration of changes over a 30-year period in the misuse of firearms and cutting/stubbing weapons within the same geographical area. Overall, there has been a notable decrease in homicides overall (from 54 % to 44 %), particularly those involving firearms (from 53.5 % to 36.5 %), alongside an increase in homicides committed with cutting/stubbing weapons (from 46.5 % to 63.5 %). However, when considering homicides and suicides together, firearms still account for the majority of deaths (56.7 % vs 43.3 %, ratio 1.3:1), though the gap has narrowed compared to previous years. Moreover, there has been a rise in homicides occurring in domestic settings (&gt;40 %) with family members as perpetrators (37 %), and an increase in cases involving legally owned firearms (from 18 % to 34 %). Concurrently, the proportion of suicides has also increased (from 46 % to 56 %), highlighting the prevalent use of firearms (72.5 %). Overall, a different scenario emerges compared to the past, yet the misuse of firearms and cutting/stubbing weapons remains a persistent issue in society. This underscores the need for ongoing monitoring of such incidents and targeted efforts for prevention and regulation.</div></div>","PeriodicalId":16098,"journal":{"name":"Journal of forensic and legal medicine","volume":"114 ","pages":"Article 102921"},"PeriodicalIF":1.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144502595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This narrative review examines the long-term implications of the pandemic on forensic psychiatric populations, mental health service provision, and the justice system. Evidence suggests that rates of severe mental illness, including psychosis, depression, and anxiety, have increased among forensic patients, exacerbated by isolation, stress, and reduced access to care. Additionally, substance use disorders, and co-occurring psychiatric conditions have become more prevalent, complicating treatment and rehabilitation efforts. The pandemic also accelerated the adoption of telepsychiatry in forensic settings, improving accessibility but raising concerns about the reliability of remote assessments for competency evaluations and risk assessments. Inpatient and prison-based forensic psychiatric services experienced staff shortages, increased patient aggression, and limited access to therapeutic programs, further straining the system. Court closures and legal case backlogs delayed forensic evaluations, raising human rights concerns for detained individuals. Ethical dilemmas emerged regarding involuntary hospitalization, treatment prioritization, and resource allocation. As the forensic mental health field transitions into a post-pandemic landscape, key lessons include the need for hybrid forensic assessment models, strengthened forensic infrastructure, and better integration of legal and clinical perspectives. Future research should focus on developing resilient forensic mental health policies and ensuring equitable access to care while maintaining legal and ethical standards.</div></div>","PeriodicalId":16098,"journal":{"name":"Journal of forensic and legal medicine","volume":"114 ","pages":"Article 102920"},"PeriodicalIF":1.2,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
