Addressing the limited access to treatments for alcohol dependence, we developed ALM-002, a therapeutic application to be "prescribed" for non-abstinence-oriented treatment in internal medicine settings. Our objective was to preliminarily assess the efficacy and safety of ALM-002. In a multicenter, open-label randomized controlled trial, participants aged ≥20 with alcohol dependence and daily alcohol consumption exceeding 60 g for men and 40 g for women, without severe complications, were randomly assigned to either the intervention group using ALM-002 or the treatment-as-usual control group. Participant in both groups received individual face-to-face sessions by physicians at weeks 0, 4, 8, and 12. The primary endpoint was the change in heavy drinking days (HDDs) from week 0 to week 12. A mixed model for repeated measures was employed. We enrolled 43 participants: 22 in the intervention group and 21 in the control group. A significant reduction in HDDs every 4 weeks from week 0 to week 12 was observed, with a between-group difference of −6.99 days (95% CI: −12.4 to −1.6 days, standardized mean difference: −0.80). These results indicate the potential of ALM-002 as a viable treatment for alcohol dependence. Further studies are needed to evaluate the clinical potential of ALM-002. [ABSTRACT FROM AUTHOR]

We aimed to assess the prevalence of hazardous drinking and potential alcohol dependence among Japanese primary care patients, and their readiness to change and awareness of others' concerns. From July to August 2023, we conducted a multi-site cross-sectional study as a screening survey for participants in a cluster randomized controlled trial. The trial included outpatients aged 20–74 from primary care clinics. Using the Alcohol Use Disorders Identification Test (AUDIT) alongside a self-administered questionnaire, we evaluated the prevalence of hazardous drinking and suspected alcohol dependence, patients' readiness to change, and their awareness of others' concerns. Among the 1388 participants from 18 clinics, 22% (95% confidence interval (CI): 20% to 24%) were identified as engaging in hazardous drinking or suspected of being alcohol dependent. As the AUDIT scores increased, so did their readiness to change. However, only 22% (95%CI: 16% to 28%) of those with scores ranging from 8 to 14 reported that others, including physicians, had expressed concerns about their drinking during the past year. For those with scores of 15 or higher, the figure was 74%. This study underscores the need for universal or high-risk alcohol screening and brief intervention in Japanese primary care settings.

Purpose: Early post-operative delirium (EPOD) is a frequent complication following colorectal surgery. The present study investigated the risk factors for EPOD after laparoscopic colorectal surgery in elderly patients. Methods: A retrospective study was conducted among 208 patients ≥70 years old who underwent laparoscopic colorectal surgery. Univariate and multivariate analyses were performed to determine the clinicopathological factors associated with the EPOD. Results: The overall incidence of EPOD was 10.1% (21/208). The univariate analysis showed that an older age (≥80 years old; P=0.002), sleeping pill medication before surgery (P=0.037), a history of dementia (P=0.030) and cerebrovascular disease (P=0.017), elevated levels of D-dimer (P=0.016), maximum intraoperative temperature ≥37 °C (P=0.036), and non-continuous usage of droperidol with analgesia (P=0.005) were associated with EPOD. The multivariate logistic regression analysis revealed an older age (≥80 years old; odds ratio [OR]: 6.26, 95% confidence interval [CI]: 1.94–20.15, P=0.002), sleeping pill medication before surgery (OR: 5.39, 95% CI: 1.36–21.28, P=0.016), history of cerebrovascular disease (OR: 3.91, 95% CI: 1.12–13.66, P=0.033), and maximum intraoperative temperature ≥37 °C (OR: 5.10, 95% CI: 1.53–16.92, P=0.008) to be independent risk factors. When the patients were divided into groups according to the number of positive risk factors, the prevalence rate was 6.5%, 16.0%, and 63.6% for patients with 1, 2, and 3 positive risk factors, respectively. Conclusion: Our findings suggest that an older age, sleeping pill medication before surgery, history of cerebrovascular disease, and maximum intraoperative temperature ≥37 °C are independent risk factors of EPOD after laparoscopic colorectal surgery in elderly patients.

• We assessed chatbot effects on problem gambling, with or without therapist support. • Gambling problems were improved regardless of the presence or absence of therapist support. • Therapist support showed no additional effect on gambling symptoms. • Examining the appropriate intensity and modality of therapist support is needed. Internet-based interventions can be a promising option for individuals with problem gambling facing barriers to seeking help. This study aimed to directly compare the effects of therapist-guided Internet interventions with unguided ones on gambling-related behavior, cognition, and stage of change including help-seeking intention. We conducted a participant-blinded randomized controlled trial of therapist-guided versus unguided groups with a 12-week follow-up. Both groups received self-help chatbot-delivered cognitive behavioral therapy. Additionally, at baseline and weeks 1, 2, 3, and 4, the guided group received personalized feedback messages from therapists based on their gambling diary and questionnaire responses. The unguided group received reminders of assessments from research assistants. The primary outcome was the change in scores on the Gambling Symptoms Assessment Scale (G-SAS) over 12 weeks. Secondary outcomes included the stage of change including help-seeking intention, money wagered, gambling frequency, and gambling-related cognitions. We included 139 participants with a mean Problem Gambling Severity Index total score of 14.6 and a mean G-SAS total score of 27.0 who sought information about gambling problems. Both groups demonstrated substantial decreases in their G-SAS scores from baseline to week 12 (-10.2, 95% CI: −7.67 to −12.7 for the guided group, and 11.7, 95% CI: −9.05 to −14.3 for the unguided group). However, we did not find a significant between-group difference (1.49, 95% CI: −2.20 to 5.17). Regarding the stage of change including help-seeking intention, there were also no between-group differences. Minimum therapist support did not have an additive effect on the self-help chatbot intervention on gambling symptoms, behavior, and the stage of change including help-seeking intention.

Aims: The use of new psychoactive substances (NPS) has become increasingly widespread over the last decade, in Japan and internationally. NPS are associated with a range of increasingly serious clinical, public, and social issues. Political measures to ameliorate the effects of NPS in Japan have focused on tightening regulation rather than establishing treatment methods. The current study sought to compare the neuropsychiatric symptoms of patients with NPS‐related disorders across several years. We examined patients who attended specialized hospitals for treating addiction, to elucidate the impacts of legal measures to control NPS. Methods: Subjects (n = 864) were patients with NPS‐related disorders who received medical treatment at eight specialized hospitals for treating addiction in Japan between April 2012 and March 2015. Clinical information was collected retrospectively from medical records. Results: Among psychiatric symptoms, the ratio of hallucinations/delusions decreased over time across 3 years of study (first year vs second year vs third year: 40.1% vs 30.9% vs 31.7%, P = 0.037). Among neurological symptoms, the ratio of coma/syncope increased over the 3‐year period (7.8% vs 11.0% vs 17.0%, P = 0.002), as did the ratio of convulsions (2.8% vs 4.3% vs 9.7%, P = 0.001). Conclusion: The symptoms associated with NPS were primarily psychiatric in the first year, while the prevalence of neurological symptoms increased each year. The risk of death and the severity of symptoms were greater in the third year compared with the first year, as regulation of NPS increased. [ABSTRACT FROM AUTHOR]
