RESUMO
The co-occurrence of gambling disorder (GD) and attention-deficit/hyperactivity disorder (ADHD) has been widely reported. In this study, we aimed to investigate the social background, clinical characteristics, and clinical course of initial-visit GD patients with and without ADHD in a Japanese psychiatric hospital. We recruited 40 initial-visit GD patients and collected comprehensive information by self-report questionnaires, direct interviews, and medical records. 27.5% of the GD patients had comorbid ADHD. Compared to the GD patients without ADHD, those with ADHD had significantly higher comorbidity rates of autism spectrum disorder (ASD), lower rates of marriage, slightly less years of education and marginally lower employment rates. On the other hand, the GD patients with ADHD showed higher treatment retention rates and participation rates in the mutual support group. Despite presenting with disadvantageous characteristics, GD patients with ADHD exhibited a more favourable clinical course. Therefore, clinicians should be mindful of the possibility of ADHD comorbidity and the potential for better clinical outcomes among GD patients with ADHD.

BACKGROUND AND AIMS: Relapse is common in alcohol dependence (AD) and alcohol use disorder (AUD), so alcohol reduction therapy should be measured over as long a period as possible; however, existing reviews do not consider the duration of treatment and therefore alcohol reduction therapy may not have been appropriately evaluated. This review evaluated the efficacy and safety of alcohol reduction pharmacotherapy in patients with AD or AUD according to the duration of treatment. METHODS: We conducted a systematic review and network meta-analysis of randomized controlled trials (RCTs) that assessed 15 pharmacological agents. MEDLINE, Embase, PsycINFO, the Cochrane Central Register of Controlled Trials, the ClinicalTrials.gov and the International Clinical Trials Registry Platform were searched for eligible trials through to May 2021. Outcomes were heavy drinking days (HDD), total alcohol consumption (TAC), any adverse event and days without drinking. RESULTS: Fifty-five RCTs (n = 8891) were included. Nalmefene was superior to placebo for reducing HDD (standard mean difference [SMD] -0.28, 95% confidence interval [CI] -0.37, -0.18) and TAC (SMD -0.25, 95% CI -0.35, -0.16) in the long-term, but not in the short-term. Topiramate was superior to placebo for reducing HDD (SMD -0.35, 95% CI -0.59, -0.12) and days without drinking (SMD 0.46, 95% CI 0.11, 0.82), and baclofen was superior for reducing TAC (SMD -0.70, 95% CI -1.29, -0.11), in the short-term. The frequency of adverse events was higher with nalmefene and topiramate than with placebo. CONCLUSION: Nalmefene, topiramate and baclofen may be effective as alcohol reduction pharmacotherapy; however, only nalmefene has demonstrated long-term efficacy, and nalmefene and topiramate have a significantly higher frequency of adverse events compared with placebo.

The present experiments were performed to clarify the brain sites whose activity is affected exclusively by cortical spreading depression (CoSD). For this purpose, Fos protein, a product of an immediate early gene, was used as a marker of neuronal activation. Because Fos can be induced by many manipulations such as stress stimuli, we verified CoSD-induced Fos expression by excluding the influence of other factors such as anaesthesia and surgical manipulation. CoSD was induced by applying a KCl solution directly to the dura mater over the cerebral cortex, and Fos expression in the brain was assessed by immunohistochemistry using antibodies against Fos protein. We found that during CoSD, Fos expression was increased specifically in the magnocellular region of the hypothalamic paraventricular nucleus (PVN), as well as in the ipsilateral cortex, whereas reduced Fos expression was observed in both the parvocellular region of the PVN and the whole cortex contralateral to the CoSD site. Consistent with the reduced Fos expression, approximately 40% of neurons in the contralateral cortex revealed a suppression of electrical activity during CoSD. These results suggest that in addition to the ipsilateral cortex, CoSD affects Fos expression exclusively in the PVN and the contralateral cortex.

AIM: The aim of this study was to examine the speed of response, doses, and safety of treatment with second-generation antipsychotics (SGAs) in patients at ultra-high risk (UHR) compared to those with schizophrenia. METHODS: A 12-week open-label, prospective study of SGAs was performed in UHR patients and those with first-episode schizophrenia (FES) and multi-episode schizophrenia (MES). The subjects were 14-30 years old and were recruited at Zikei Hospital, Okayama, Japan from December 1, 2006 to December 1, 2011. Treatment was carried out in a natural setting in an open-label format, but clinical evaluation was performed blind. The clinical rating scales include the Global Assessment of Functioning (GAF), the Positive and Negative Syndrome Scale (PANSS), and the Clinical Global Impression-Severity scale (CGI-S). RESULTS: UHR (n = 17), FES (n = 23), and MES (n = 21) patients all showed significant improvements on the GAF, PANSS, and CGI-S. However, the UHR patients showed significantly greater improvement on the GAF at weeks 4, 8, and 12 compared to the other groups, and a significantly lower modal dose of SGAs (chlorpromazine equivalent: 183 [201.1] mg/day, mean [SD]) was needed for improvement in the UHR group. Each group was also prescribed anticholinergic agents during the study period and the UHR group had significantly fewer extrapyramidal symptoms (only 6%) compared with the FES group. CONCLUSION: Our findings suggest that UHR patients have a better response to SGAs compared to patients with schizophrenia, and that these drugs can be given safely by minimizing the dosage of SGAs and using anticholinergic agents.
RESUMO
AIM: Japanese psychiatrists have increasingly reported patients with depression that does not seem to fit the criteria of the ICD-10 and the DSM-IV, and which has recently been called modern type depression (MTD). We explored whether MTD is frequently seen in Japan and also in other countries, and if so, how patients with MTD are diagnosed and treated. METHODS: The questionnaires, with two case vignettes (traditional type depression (TTD) and MTD), were sent to psychiatrists in Australia, Bangladesh, India, Iran, Japan, Korea, Taiwan, Thailand and the USA. Participants rated their opinions about each case's prevalence in their country, etiology, diagnosis, suicide risk, and treatment using Likert scales. RESULTS: Out of 247 responses (123 from Japan and 124 from other countries), two hundred thirty-nine valid responses were received. MTD was recognized in all participating countries, and especially in urban areas. Generally, the factor of personality was regarded as the most probable cause of MTD. Whereas about 90% of Japanese psychiatrists applied the ICD/DSM criteria to TTD, only about 60% applied the criteria to MTD. CONCLUSION: Our results indicate that Japan's MTD seems to be occurring in many other countries, and that the present ICD/DSM criteria may not be sufficient to diagnose MTD. Therefore, it could be an important candidate for a new international diagnostic criterion as a subtype of depression. A clear diagnostic framework and consensus on the interventions to treat MTD would be valuable. Further clinical, psychopathological and international epidemiological studies are needed to confirm our preliminary findings of MTD.
