Longitudinal changes in depressive symptoms associated with social isolation after the Great East Japan Earthquake in Iwate Prefecture: findings from the TMM CommCohort study.

BACKGROUND: Whether past disaster experiences affect the association between changes in social isolation and depressive symptoms is largely unknown. This study examined the association between changes in social isolation and depressive symptoms among survivors who experienced earthquake damage in the aftermath of the Great East Japan Earthquake (GEJE). METHODS: We analyzed longitudinal data from 10,314 participants who responded to self-report questionnaires on the Lubben Social Network Scale-6 (LSNS-6) and the Center for Epidemiological Studies-Depressive Scale (CES-D) in both the baseline survey (FY2013 to FY2015) and follow-up survey (FY2017 to FY2019) after the GEJE. According to changes in the presence of social isolation (< 12 of LSNS-6) at two time points, participants were categorized into four groups: "not socially isolated," "improved socially isolated," "newly socially isolated," and "continuously socially isolated." At the follow-up survey, a CES-D score of ≥ 16 indicates the presence of depressive symptoms. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) were estimated using the logistic regression analysis to examine the influence of the change in social isolation over four years on depressive symptoms. RESULTS: Participants who were newly socially isolated had a significantly higher prevalence of depressive symptoms than those who were not socially isolated (AOR = 1.89, 95% CI = 1.61 - 2.23). In addition, AORs were highest for those who were continuously socially isolated and had experienced house damage (AOR = 2.17, 95% CI = 1.73 - 2.72) and those who were newly socially isolated and had not experienced the death of family members due to the GEJE (AOR = 1.88, 95%CI = 1.60 - 2.22). CONCLUSION: Our longitudinal findings suggest that being newly or continuously socially isolated is associated with a risk of depressive symptoms, not only among those who had experienced house damage or the death of a family member, but also those who had not, in the disaster-affected area. Our study underlines the clinical importance of social isolation after a large-scale natural disaster and draws attention to the need for appropriate prevention measures.

Development of an individual fitness score (IFS) based on the depression treatment guidelines of in the Japanese Society of Mood Disorders.

AIM: Treatment guidelines are designed to assist patients and health care providers and are used as tools for making treatment decisions in clinical situations. The treatment guidelines of the Japanese Society of Mood Disorders establish treatment recommendations for each severity of depression. The individual fitness score (IFS) was developed as a simple and objective indicator to assess whether individual patients are practicing treatment by the recommendations of the depression treatment guidelines of the Japanese Society of Mood Disorders. METHODS: The EGUIDE project members determined the IFS through the modified Delphi method. In this article, the IFS was calculated based on the treatment of depressed patients treated and discharged between 2016 and 2020 at facilities participating in the EGUIDE project. In addition, we compared scores at admission and discharge. RESULTS: The study included 428 depressed patients (mild n = 22, moderate/severe n = 331, psychotic n = 75) at 57 facilities. The mean IFS scores by severity were statistically significantly higher at discharge than at admission with moderate/severe depression (mild 36.1 ± 34.2 vs. 41.6 ± 36.9, p = 0.49; moderate/severe 50.2 ± 33.6 vs. 55.7 ± 32.6, p = 2.1 × 10-3; psychotic 47.4 ± 32.9 versus 52.9 ± 36.0, p = 0.23). CONCLUSION: We developed the IFS based on the depression treatment guideline, which enables us to objectively determine how close the treatment is to the guideline at the time of evaluation in individual cases. Therefore, the IFS may influence guideline-oriented treatment behavior and lead to the equalization of depression treatment in Japan, including pharmacotherapy.

Implementations of an evidence-based assertive case management intervention for suicide attempters: Post-ACTION-J Study (PACS).

Aim: An assertive case management intervention program, ACTION-J, proved effective for preventing suicide attempters from reattempting suicide within 6 months. The ACTION-J randomized trial was conducted as part of the "National Strategic Research Projects." The program has been covered by the national medical payment system of Japan since 2016. The aim of the Post-ACTION-J Study (PACS) was to examine the current implementation status of assertive case management in a real-world clinical setting. Methods: PACS was a prospective, multicenter registry cohort study. The participants were suicide attempters admitted to the emergency departments of 10 participating medical facilities from October 2016 to September 2018. The assertive case management intervention developed by the ACTION-J Study was offered to all patients, and the primary outcome was the duration and frequency of use of the intervention at 6 months. Results: A total of 1159 patients were admitted to emergency departments after a suicide attempt during the study period, 144 of whom were included in our analysis. The proportion of participants who received the intervention for 6 months was 72.2% (104/144), and 63.9% (92/144) of the patients completed ≥7 case management interviews within 6 months. Conclusion: The findings of this study indicate successful implementation of an assertive case management intervention program based on the ACTION-J Study in a real-world clinical setting, following its integration with the national medical payment scheme in Japan. The study provided the useful information that could improve the implementation of assertive case management interventions in future.

Outcomes of dutasteride discontinuation in patients with benign prostatic hypertrophy.

To the Editor, Benign prostatic hyperplasia (BPH) is a common cause of lower urinary tract symptoms (LUTS) in elderly males. The current guidelines recommend the use of a 5-alpha reductase inhibitor (5ARI) to treat males with moderate-to-severe LUTS and an enlarged prostate. Combination therapy with an alpha blocker and a 5ARI has proven effective at ameliorating LUTS and reducing the total prostate volume (TPV) and the risk of the disease progression.

The choice of therapeutic agent in female overactive bladder patients in real-world practice.

OBJECTIVE: The reasons why anticholinergic drugs or ß3 adrenergic agonists are selected as treatments for overactive bladder (OAB) are unclear. The aim of this study was to investigate the background data of female OAB patients that were prescribed anticholinergic drugs or ß3 adrenergic agonists in a real-world setting. MATERIALS AND METHODS: Between January 2013 and December 2014, 75 patients who had been diagnosed with OAB were included in this study. Administered medications, age, the persistence on treatment rate at one-year, medical history, pretreatment total Overactive Bladder Symptom Score (OABSS), pretreatment score for each OABSS factor, body mass index (BMI), and various comorbidities were evaluated retrospectively. Since there were many types of anticholinergic drugs and few patients, we grouped the patients into those that were prescribed anticholinergic drugs (group A) and those that were prescribed ß3 adrenergic agonists (group B). RESULTS: 75 patients (29 in group A and 46 in group B) were included in this study. There were no significant differences in age, BMI, obesity, medical history, pretreatment total OABSS, or pretreatment score for each OABSS factor. There was a significant difference in the post-voiding residual urine volume (PVR) between the groups (group A: 22 ml, group B: 9 ml; p = 0.0252). The 1-year persistence on treatment rate was 28% in both groups. CONCLUSIONS: There were no significant differences in clinical characteristics of patients who were prescribed anticholinergics and ß3 adrenergic agonists for OAB treatment, but a marginal difference of PVR value before treatment. The 1-year persistence rates of anticholinergic drugs and ß3 adrenergic agonists were considered to be almost equivalent.

Association between Social Isolation and Total Mortality after the Great East Japan Earthquake in Iwate Prefecture: Findings from the TMM CommCohort Study.

This study aimed to investigate whether social isolation is associated with mortality, together with the effect of the Great East Japan Earthquake on mortality, due to the social isolation of community residents living in the affected areas, using data from the Tohoku Medical Megabank Project Community-Based Cohort Study. A total of 22,933 participants (8059 men and 14,874 women), who were free from cancer and cardiovascular disease, were followed up with death as an endpoint for five years. Social isolation was assessed using the Lubben Social Network Scale (cut-off, 11/12). Using Cox proportional hazards models, hazard ratios (HRs) of total mortality and 95% confidence intervals (CIs) associated with social isolation (no isolation as the reference) were estimated. The latter was significantly associated with an increased risk of total mortality (1.38 (1.04-1.83) in men and 1.49 (1.02-2.19) in women). Moreover, among those with social isolation, the risk of mortality was significantly higher, especially for women with house damage and men who had experienced a death in the family. The disaster may have raised the risk of mortality due to social isolation.

Lessons learned from psychosocial support and mental health surveys during the 10 years since the Great East Japan Earthquake: Establishing evidence-based disaster psychiatry.

Post-disaster mental health and psychosocial support have drawn attention in Japan after the 1995 Great Hanshin-Awaji Earthquake, with mental health care centers for the affected communities being organized. After the catastrophe, a reconstruction budget was allocated to organize mental health care centers to provide psychosocial support for communities affected by the 2007 Chuetsu offshore earthquake, the 2011 Great East Japan Earthquake, and the 2016 Kumamoto Earthquake. There were several major improvements in post-disaster mental health measures after the Great East Japan Earthquake. The Disaster Psychiatric Assistance Team system was organized after the earthquake to orchestrate disaster response related to the psychiatric health system and mental health of the affected communities. Special mental health care efforts were drawn to the communities affected by the nuclear power plant accident through Chemical, Biological, Radiological, Nuclear, and high yield Explosives, being succeeded by measures against the coronavirus pandemic. As another new movement after the Great East Japan Earthquake, the number of surveys involving communities affected by disasters has soared. More than 10 times the number of scientific publications were made in English during the decade following the Great East Japan Earthquake, compared with the previous decades. In this review, we examined the results and issues acquired in the 10 years since the Great East Japan Earthquake, proposing evidence-based disaster psychiatry as the direction of future mental health measures related to emergency preparedness and response.

3-day intervention program for family members of hikikomori sufferers: A pilot randomized controlled trial.

Backgrounds: Hikikomori, pathological social withdrawal, is becoming a crucial mental health issue in Japan and worldwide. We have developed a 3-day family intervention program for hikikomori sufferers based on Mental Health First Aid (MHFA) and Community Reinforcement and Family Training (CRAFT). This study aims to confirm the effectiveness of the 3-day program by a randomized controlled trial. Methods: This study was registered on the UMIN Clinical Trials Registry (UMIN000037289). Fifteen parents were assigned to the treat as usual (TAU) group (TAU only; Age Mean, 65.6; SD, 7.8), and 14 to the Program group (program + TAU; Age Mean, 67.9; SD, 8.6). This study was discontinued due to the COVID-19 pandemic; the recruitment rate was 36.3% of our target sample size of 80. Results: Perceived skills improved temporally and stigma temporally worsened in the TAU group. Confidence decreased and attitude showed no change in both groups. Aggressive behaviors of hikikomori sufferers were significantly worsened in the Program group; however, no serious domestic violence was reported. In the TAU group, Avoidance and irregular life patterns were improved. Activity levels were worsened in both groups. Two participants (16.7%) in the Program group and one participant (7.7%) in the TAU group reported actual behavioral changes (e.g., utilizing support). Conclusion: We could not draw general conclusions on the effectiveness of the program due to the study discontinuation. Nevertheless, this study indicates the necessity for revision of the program to improve family members' confidence in engaging with hikikomori sufferers, with safer approaching by families.

[Adult Prepubertal-Type Teratoma Diagnosed Using Fish Analysis : A Case Report].

A 34-year-old man visited our hospital complaining of a small painless left scrotal mass. His serum alpha-fetoprotein and human chorionic gonadotropin-beta levels were normal. Ultrasonography revealed a solitary 14 mm mass. Magnetic resonance imaging revealed a mass with high intensity on T2-weighted imaging. Computed tomography revealed a heterogeneous tumor in the left scrotum. Left high orchiectomy was performed. The histopathological diagnosis was a teratoma without germ cell neoplasia in situ (GCNIS). Fluorescence in situ hybridization analysis showed no appearance of i(12p). The patient was clinically diagnosed as having a prepubertal-type testicular teratoma. Adult teratomas contain GCNIS and are aggressively treated as malignant germ cell tumors. However, a prepubertal-type teratoma is benign and does not relapse. It is essential to validate the appearance of i(12p) to differentiate prepubertal and postpubertal-type teratoma.

The Association Between Hot Flashes and Renal Dysfunction After Androgen Deprivation Therapy With Radiotherapy in Japanese Patients With High-risk Prostate Cancer.

BACKGROUND/AIM: We investigated the changes in and characteristics of renal function in Japanese patients with high-risk prostate cancer (PCa) who underwent radiotherapy and long-term androgen deprivation therapy (ADT), including those seen after the ADT was discontinued. PATIENTS AND METHODS: Among 60 patients who were pathologically diagnosed with PCa and received ADT for 24 months and radiotherapy, 36 patients who underwent treatment for stage B or C PCa were eligible. We assessed renal function using the estimated glomerular filtration rate (eGFR) and investigated the rate of change in the eGFR (ΔeGFR) during and after ADT. Univariate and multivariate logistic analyses were carried out to identify clinical factors that were significantly associated with renal dysfunction at 36 months. RESULTS: The incidence of renal dysfunction at 36 months was 75% (27/36). Multivariate analysis showed that the presence/absence of HF was an independent predictor of renal dysfunction at 36 months. CONCLUSION: Renal function tended to recover after ADT was received for 24 months and subsequently discontinued. The presence/absence of HF represents new and meaningful information for patients receiving ADT, and high-risk PCa patients prior to ADT.

Effectiveness of assertive case management for patients with suicidal intent.

The aim of this study was to examine the effectiveness of assertive case management intervention in preventing suicidal behaviour in self-poisoning patients. We conducted a secondary analysis of data from the ACTION-J study. Participants were self-poisoning patients with clear suicide intent admitted to emergency departments and with a primary psychiatric diagnosis (as per DSM-IV-TR axis 1). Patients were randomly assigned either to assertive case management or enhanced usual care. The primary outcome measure was the incidence of a first recurrent suicide attempt within 6 months. This study is registered at ClinicalTrials.gov (NCT00736918) and UMIN-CTR (C000000444). There were 297 self-poisoning patients in the intervention group and 295 in the control group. The primary outcome was significantly lower in the intervention group than in the control group. The incidence of a first recurrent suicide attempt within 1 and 3 months was also significantly lower in the intervention group, as was the number of overall self-harm episodes over the entire study period. Furthermore, the number of non-suicidal self-harm episodes and suicide attempts was significantly lower in the intervention group. Assertive case management is effective when promptly introduced in a hospital setting as an intervention following a suicide attempt, particularly for self-poisoning patients.

Association between the social isolation and depressive symptoms after the great East Japan earthquake: findings from the baseline survey of the TMM CommCohort study.

BACKGROUND: Social isolation and mental health issues have become a severe problem in disaster areas in the Great East Japan Earthquake. This study examined whether the combination of the house damage and social isolation or the combination of the death of family members and social isolation is associated with depressive symptoms among survivors using the baseline study data of the Tohoku Medical Megabank Project Community-Based Cohort Study (TMM CommCohort Study). METHODS: We used cross-sectional data from a baseline survey of 48,958 participants (18,423 males, 30,535 females; aged 60.1 ± 11.2 years) to examine the association between social isolation measured by the Lubben social network scale 6 (LSNS-6) and depressive symptoms measured by the Center for Epidemiological Studies-Depressive Scale (CES-D). The presence of social isolation and depressive symptoms was defined by an LSNS-6 score of < 12 and a CES-D score of ≥16, respectively. We performed a logistic regression analysis to determine the multivariable-adjusted odds ratio (95% confidence interval) [AOR (95% CI)] for depressive symptoms according to sex in the social isolation in comparison to without social isolation, and the associations of the combination of the house damage or the death of family members and social isolation and depressive symptoms. RESULTS: Social isolation was significantly associated with depressive symptoms (males: OR = 1.87; 95% CI = 1.72-2.04, females: OR = 2.13; 95% CI = 2.00-2.26). Both males and females respondents with severe house damage and social isolation had a greater risk of depressive symptoms in comparison to those with an undamaged house and without social isolation (males: OR = 3.40; 95% CI = 2.73-4.24, females: OR = 2.92; 95% CI = 2.46-3.46). The risk of depressive symptoms was also higher in both males and females respondents with the death of family members and social isolation in comparison to those without the death of family members and without social isolation (males: OR = 2.18; 95% CI = 1.90-2.50, females: OR = 2.60; 95% CI = 2.35-2.88). CONCLUSION: The findings suggested that a combination of social isolation and severe house damage and the death of family members caused by a large-scale natural disaster was associated with a higher risk of depressive symptoms although the interaction was not statistically significant.

Effectiveness of suicide prevention gatekeeper training for university teachers in Japan.

Suicide is a leading cause of death among Japanese college and university students. Our previous study showed that the gatekeeper training (GKT) program significantly improved competence and confidence in the management of suicidal students in university administrative staff. However, we could not determine which component of the program was effective, nor if this program was effective for university teachers as well. In the current study, 81 university teachers were recruited; 63 of them received a general mental health lecture (MHL) and 18 of them received a 2.5 -h GKT program based on the Mental Health First Aid program. Competence and confidence in managing suicide intervention and behavioral intention as a gatekeeper were assessed by a self-report questionnaire before and immediately after the intervention. As a result, we found a significant improvement in competence in the management of suicidal students in the GKT group compared to the MHL group. We also found significant improvements in confidence in the management of suicidal students and behavioral intention as gatekeepers in the GKT group, although the questionnaires for these outcomes were not validated. The program satisfaction score was significantly higher in the GKT group than in the MHL group. To our knowledge, this is the first study to evaluate a GKT program for university teachers in Japan. By comparing the two groups, we explicitly confirmed that active involvement of the participants is crucial for effective suicide prevention training.

Validation of the Effectiveness of Neutrophil-to-lymphocyte Ratio (NLR) as a Predictive Factor in Patients Undergoing Prostate Biopsy With Prostate Specific Antigen (PSA) Between 4.0 and 10.0 ng/ml.

BACKGROUND/AIM: This study aimed to access the effectiveness of serum neutrophil-to-lymphocyte ratio (NLR) in patients undergoing prostate needle biopsy with a prostate specific antigen (PSA) between 4.0 and 10.0 ng/ml. PATIENTS AND METHODS: A total of 633 cases were eligible. We evaluated several factors including age, PSA, PSA-density (PSAD), platelet-to-lymphocyte ratio (PLR) and NLR in the presence or absence of prostate cancer (PCa), retrospectively. We evaluated statistically the associations between each factor and pathological findings or Gleason score. RESULTS: A total of 201 were evaluated in this study. Regarding the presence or absence of prostate cancer, there were statistically significant differences in age, PSA levels, PSAD, the PLR and NLR. The mean NLR value of the patients with PCa was significantly lower compared to the entire cohort. Multivariate analysis showed that age, PSAD, and NLR were independent risk factors predicting PCa. CONCLUSION: For patients having a PSA between 4.0 and 10.0 ng/ml, NLR was a predicting factor of PCa prior to prostate needle biopsy and an effective biomarker and useful tool for avoiding unnecessary biopsies.

Medicine at mass gatherings: current progress of preparedness of emergency medical services and disaster medical response during 2020 Tokyo Olympic and Paralympic Games from the perspective of the Academic Consortium (AC2020).

Mass gatherings are events characterized by "the concentration of people at a specific location for a specific purpose over a set period of time that have the potential to strain the planning and response resources of the host country or community." Previous reports showed that, as a result of the concentration of people in the limited area, injury and illness occurred due to several factors. The response plan should aim to provide timely medical care to the patients and to reduce the burden on emergency hospitals, and to maintain a daily emergency medical services system for residents of the local area. Although a mass gathering event will place a significant burden on the local health-care system, it can provide the opportunity for long-term benefits of public health-care and improvement of daily medical service systems after the end of the event. The next Olympic and Paralympic Games will be held in Tokyo, during which mass gatherings will occur on a daily basis in the context of the coronavirus disease (COVID-19) epidemic. The Academic Consortium on Emergency Medical Services and Disaster Medical Response Plan during the Tokyo Olympic and Paralympic Games in 2020 (AC2020) was launched 2016, consisting of 28 academic societies in Japan, it has released statements based on assessments of medical risk and publishing guidelines and manuals on its website. This paper outlines the issues and countermeasures for emergency and disaster medical care related to the holding of this big event, focusing on the activities of the academic consortium.

False-positive 123I-metaiodobenzylguanidine scan in a patient with renal cell carcinoma: A case of chromophobe renal cell carcinoma oncocytic variant with a complicated clinical course.

INTRODUCTION: 123I-metaiodobenzylguanidine scanning has high sensitivity and specificity for the diagnosis of tumors derived from sympathetic nerves or the adrenal medulla. We report the rare case of a 123I-metaiodobenzylguanidine false-positive renal cell carcinoma. CASE PRESENTATION: The patient was referred to our hospital with an incidental left renal mass during evaluation for hypertension. An ovarian tumor and prominent ascites were also observed. Serum and urine catecholamine levels were high to suspect a catecholamine-producing tumor of the kidney. 123I-metaiodobenzylguanidine scintigraphy showed increased 123I-metaiodobenzylguanidine intake in the tumor. Laparoscopic radical left nephrectomy was performed. The pathologic diagnosis was an oncocytic variant of chromophobe renal cell carcinoma. No pheochromocytoma features were found. CONCLUSION: We report the first case of a 123I-metaiodobenzylguanidine false-positive renal cell carcinoma. This case was diagnosed with primary aldosteronism and Meigs' syndrome, which made the clinical course more complicated.

Successful Response to Nivolumab Plus Ipilimumab Therapy in a Hemodialysis Patient With Metastatic Renal Cell Carcinoma.

Background/Aim: There are few reports about the administration of nivolumab plus ipilimumab to hemodialysis patients and their efficacy and safety have not been established yet. Case Report: A 74-year-old male, who was receiving hemodialysis, was presented with metastatic renal cell carcinoma (mRCC). Two years later, more metastases were found, hence, immunotherapy involving nivolumab plus ipilimumab was initiated. After two doses of immunotherapy, interstitial pneumonia was observed. Thus, steroid pulse therapy was administered immediately. Subsequently, computed tomography (CT) findings and symptoms improved markedly. One month later, a CT scan showed a nodular shadow and an air cavity. A fungal infection was strongly suspected, so an antifungal drug was administered. Conclusion: Combination immunotherapy with nivolumab plus ipilimumab was demonstrated to be effective in a hemodialysis patient with mRCC.

Study Profile of the Tohoku Medical Megabank Community-Based Cohort Study.

BACKGROUND: We established a community-based cohort study to assess the long-term impact of the Great East Japan Earthquake on disaster victims and gene-environment interactions on the incidence of major diseases, such as cancer and cardiovascular diseases. METHODS: We asked participants to join our cohort in the health check-up settings and assessment center based settings. Inclusion criteria were aged 20 years or over and living in Miyagi or Iwate Prefecture. We obtained information on lifestyle, effect of disaster, blood, and urine information (Type 1 survey), and some detailed measurements (Type 2 survey), such as carotid echography and calcaneal ultrasound bone mineral density. All participants agreed to measure genome information and to distribute their information widely. RESULTS: As a result, 87,865 gave their informed consent to join our study. Participation rate at health check-up site was about 70%. The participants in the Type 1 survey were more likely to have psychological distress than those in the Type 2 survey, and women were more likely to have psychological distress than men. Additionally, coastal residents were more likely to have higher degrees of psychological distress than inland residents, regardless of sex. CONCLUSION: This cohort comprised a large sample size and it contains information on the natural disaster, genome information, and metabolome information. This cohort also had several detailed measurements. Using this cohort enabled us to clarify the long-term effect of the disaster and also to establish personalized prevention based on genome, metabolome, and other omics information.

Machine learning for effectively avoiding overfitting is a crucial strategy for the genetic prediction of polygenic psychiatric phenotypes.

The accuracy of previous genetic studies in predicting polygenic psychiatric phenotypes has been limited mainly due to the limited power in distinguishing truly susceptible variants from null variants and the resulting overfitting. A novel prediction algorithm, Smooth-Threshold Multivariate Genetic Prediction (STMGP), was applied to improve the genome-based prediction of psychiatric phenotypes by decreasing overfitting through selecting variants and building a penalized regression model. Prediction models were trained using a cohort of 3685 subjects in Miyagi prefecture and validated with an independently recruited cohort of 3048 subjects in Iwate prefecture in Japan. Genotyping was performed using HumanOmniExpressExome BeadChip Arrays. We used the target phenotype of depressive symptoms and simulated phenotypes with varying complexity and various effect-size distributions of risk alleles. The prediction accuracy and the degree of overfitting of STMGP were compared with those of state-of-the-art models (polygenic risk scores, genomic best linear-unbiased prediction, summary-data-based best linear-unbiased prediction, BayesR, and ridge regression). In the prediction of depressive symptoms, compared with the other models, STMGP showed the highest prediction accuracy with the lowest degree of overfitting, although there was no significant difference in prediction accuracy. Simulation studies suggested that STMGP has a better prediction accuracy for moderately polygenic phenotypes. Our investigations suggest the potential usefulness of STMGP for predicting polygenic psychiatric conditions while avoiding overfitting.
