Requirements for hospitals in Japan to have low operative mortality and failure-to-rescue rates.

Aim: We explored institutional factors in Japan associated with lower operative mortality and failure-to-rescue (FTR) rates for eight major gastrointestinal procedures. Methods: A 22-item online questionnaire was sent to 2119 institutional departments (IDs) to examine the association between institutional factors and operative mortality and FTR rates. IDs were classified according to the number of annual surgeries, board certification status, and locality. In addition, the top 20% and bottom 20% of IDs were identified based on FTR rates and matched with the results of the questionnaire survey. Factors associated with operative mortality were selected by multivariate analysis. Results: Of the 1083 IDs that responded to the questionnaire, 568 (213 382 patients) were included in the analysis. Operative morbidity, operative mortality, and FTR rates in the top 20% and bottom 20% of IDs were 13.1% and 8.4% (p < 0.001), 0.52% and 4.3% (p < 0.001), and 4.0% and 51.2% (p < 0.001), respectively. Based on the patients' background characteristics, the top 20% of IDs handled more advanced cases. No significant difference in locality was seen between better or worse hospital FTR rates, but fewer esophagectomies, hepatectomies, and pancreatoduodenectomies were performed in depopulated areas. Six items were found to be associated with operative mortality by multivariate logistic analysis. Only 50 (8.8%) IDs met all five factors related to better FTR rates. Conclusions: The present findings indicate that several hospital factors surrounding surgical treatment, characterized by abundant human resources, are closely related to better postoperative recovery from severe complications.

A multimodal deep learning approach for the prediction of cognitive decline and its effectiveness in clinical trials for Alzheimer's disease.

Alzheimer's disease is one of the most important health-care challenges in the world. For decades, numerous efforts have been made to develop therapeutics for Alzheimer's disease, but most clinical trials have failed to show significant treatment effects on slowing or halting cognitive decline. Among several challenges in such trials, one recently noticed but unsolved is biased allocation of fast and slow cognitive decliners to treatment and placebo groups during randomization caused by the large individual variation in the speed of cognitive decline. This allocation bias directly results in either over- or underestimation of the treatment effect from the outcome of the trial. In this study, we propose a stratified randomization method using the degree of cognitive decline predicted by an artificial intelligence model as a stratification index to suppress the allocation bias in randomization and evaluate its effectiveness by simulation using ADNI data set.

The impact of COVID-19 on the diagnosis and treatment of HCC: analysis of a nationwide registry for advanced liver diseases (REAL).

The number of cancer cases diagnosed during the coronavirus disease 2019 (COVID-19) pandemic has decreased. This study investigated the impact of the pandemic on the clinical practice of hepatocellular carcinoma (HCC) using a novel nationwide REgistry for Advanced Liver diseases (REAL) in Japan. We retrieved data of patients initially diagnosed with HCC between January 2018 and December 2021. We adopted tumor size as the primary outcome measure and compared it between the pre-COVID-19 (2018 and 2019) and COVID-19 eras (2020 and 2021). We analyzed 13,777 patients initially diagnosed with HCC (8074 in the pre-COVID-19 era and 5703 in the COVID-19 era). The size of the maximal intrahepatic tumor did not change between the two periods (mean [SD] = 4.3 [3.6] cm and 4.4 [3.6] cm), whereas the proportion of patients with a single tumor increased slightly from 72.0 to 74.3%. HCC was diagnosed at a similar Barcelona Clinic Liver Cancer stage. However, the proportion of patients treated with systemic therapy has increased from 5.4 to 8.9%. The proportion of patients with a non-viral etiology significantly increased from 55.3 to 60.4%. Although the tumor size was significantly different among the etiologies, the subgroup analysis showed that the tumor size did not change after stratification by etiology. In conclusion, the characteristics of initially diagnosed HCC remained unchanged during the COVID-19 pandemic in Japan, regardless of differences in etiology. A robust surveillance system should be established particularly for non-B, non-C etiology to detect HCC in earlier stages.

Impact of the novel coronavirus infection on pediatric surgery: an analysis of data from the National Clinical Database.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic limited the delivery of medical resources. Although surgeries are triaged according to disease severity and urgency, a delay in diagnosis and surgery can be detrimental. We conducted this study to analyze data on the impact of the COVID-19 pandemic on pediatric surgery for different diseases or disorders. METHODS: We compiled and compared data on pediatric surgical cases from 2018 to 2020, using the National Clinical Database. The number of diseases, severity, complication rates, mortality rates by disease/disorder, and the COVID-19 pandemic areas were analyzed. RESULTS: The total number of cases of pediatric surgery in 2018, 2019, and 2020 was 50,026, 49,794, and 45,621, respectively, reflecting an 8.8% decrease in 2020 from 2018 and an 8.4% decrease in 2020 from 2019. A decrease was observed when the number of patients with COVID-19 was high and was greater in areas with a low infection rate. There was a marked decrease in the number of inguinal hernia cases. The number of emergency room visits and emergency surgeries decreased, but their relative proportions increased. CONCLUSIONS: The COVID-19 pandemic decreased the number of pediatric surgeries, reflecting the limitations of scheduled surgeries and infection control measures.

A multicenter, single-arm, open-label interventional study of adherence to brexpiprazole during switching from previous antipsychotic drugs in patients with schizophrenia or schizoaffective disorder.

The rate of medication persistence was examined in patients with schizophrenia or schizoaffective disorder during switching from previously administered antipsychotics to brexpiprazole, a new dopamine D2 receptor partial agonist. A multicenter, single-arm, open-label 24-week interventional study was conducted, consisting of two 12-week consecutive periods: an initial switch (by plateau cross-titration) with the subsequent period, followed by a second maintenance period. Prior antipsychotics were olanzapine or risperidone/paliperidone. The primary and secondary outcome measures were medication persistence rates after the first 12 weeks and changes from baseline in the Specific Levels of Functioning Scale (SLOF), Subjective Well-being under Neuroleptic drug treatment Short form (SWNS), and Positive and Negative Syndrome Scale (PANSS) scores, respectively. In total, 79 patients were administered brexpiprazole and the medication persistence rate at 12 weeks was 78.5%, which was significantly higher than the predefined threshold of 65%. Regarding the prior medication, the persistence rate at 12 weeks was 84.6% for olanzapine and 72.5% for risperidone/paliperidone. Significant improvements from baseline were observed in the SLOF, SWNS, and PANSS scores. There were no adverse events of concern. Thus, brexpiprazole appeared to be a suitable antipsychotic on switching from olanzapine, risperidone, or paliperidone.

Feasibility of remote interviews in assessing disease severity in patients with major depressive disorder: A pilot study.

AIM: Interview quality is an important factor in the success of clinical trials for major depressive disorder (MDD). There is a substantial need to establish a reliable, remote clinical assessment interview system that can replace traditional in-person interviews. METHODS: We conducted a multicenter, randomized, unblinded, prospective, cross-sectional study to assess the reliability of remote interviews in patients with MDD (UMIN000041839). Eligible patients with MDD underwent remote and in-person sessions of the Montgomery-Åsberg Depression Rating Scale (MADRS) assessment performed by different raters within 28 days of providing consent. Patients were randomized to a group first assessed using in-person interviews and secondarily using remote interviews (in-person-first group) or a group first assessed by remote interviews and secondarily using in-person interviews (remote-first group). Nineteen trained people (15 clinical psychologists, 3 nurses, and 1 clinical laboratory technologist) performed interviews. RESULTS: Of 59 patients (in-person-first group, n = 32; remote-first group, n = 27) who completed both remote and in-person interviews, 51% (n = 30) were women; the mean age was 41.6 years (range, 21-64 years). There was a strong association between remote and in-person MADRS scores (r = 0.891, kappa = 0.901). An overall intraclass correlation coefficient (ICC) of 0.886 (95% confidence interval, 0.877-0.952) indicated good consistency between MADRS scores in remote and in-person interviews. The ICC decreased as the severity of depression increased. CONCLUSION: Our results suggest remote interviews are a feasible alternative option to in-person interviews in assessing symptom severity in MDD patients and could promote clinical trials in Japan.

Distinct Clinical Effects of Two RP1L1 Hotspots in East Asian Patients With Occult Macular Dystrophy (Miyake Disease): EAOMD Report 4.

Purpose: To characterize the clinical effects of two RP1L1 hotspots in patients with East Asian occult macular dystrophy (OMD). Methods: Fifty-one patients diagnosed with OMD harboring monoallelic pathogenic RP1L1 variants (Miyake disease) from Japan, South Korea, and China were enrolled. Patients were classified into two genotype groups: group A, p.R45W, and group B, missense variants located between amino acids (aa) 1196 and 1201. The clinical parameters of the two genotypes were compared, and deep learning based on spectral-domain optical coherence tomographic (SD-OCT) images was used to distinguish the morphologic differences. Results: Groups A and B included 29 and 22 patients, respectively. The median age of onset in groups A and B was 14.0 and 40.0 years, respectively. The median logMAR visual acuity of groups A and B was 0.70 and 0.51, respectively, and the survival curve analysis revealed a 15-year difference in vision loss (logMAR 0.22). A statistically significant difference was observed in the visual field classification, but no significant difference was found in the multifocal electroretinographic classification. High accuracy (75.4%) was achieved in classifying genotype groups based on SD-OCT images using machine learning. Conclusions: Distinct clinical severities and morphologic phenotypes supported by artificial intelligence-based classification were derived from the two investigated RP1L1 hotspots: a more severe phenotype (p.R45W) and a milder phenotype (1196-1201 aa). This newly identified genotype-phenotype association will be valuable for medical care and the design of therapeutic trials.

Intraventricular hemorrhage volume and younger age at surgery may be risk factors for postoperative hydrocephalus after hemispherotomy in children.

OBJECTIVE: Hemispherotomy is an effective treatment for intractable hemispheric epilepsy; however, hydrocephalus remains a common complication of the procedure. The causes of hydrocephalus following hemispherotomy have not been fully elucidated; therefore, the purpose of this study was to identify the risk factors associated with the condition. METHODS: The authors investigated the records of all patients aged < 18 years who underwent hemispherotomy at their institution between 2003 and 2020 and were monitored for hydrocephalus for at least 1 year after the procedure. To identify the risk factors for hydrocephalus, the following information about each patient was collected: sex, corrected age at surgery, body weight at surgery, previous intracranial surgery, etiology of epilepsy, results of PET for hypermetabolism, side of surgery, type of operation (vertical or horizontal approach), operation time, blood loss during surgery, use of intraventricular drainage, occurrence of intraventricular hemorrhage (IVH) on the 1st postoperative day, duration of postoperative fever of > 38°C, and maximum C-reactive protein level after the operation. Multivariate logistic regression analyses were performed. RESULTS: This study included 51 children who underwent hemispherotomies for drug-resistant epilepsy at our hospital. Seven patients (13.7%) experienced hydrocephalus and were treated with ventricular or subdural peritoneal shunts or fenestration. Multivariate logistic analysis using the Bayesian information criterion revealed that 3 factors were associated with the occurrence of hydrocephalus: age at surgery, postoperative IVH volume, and duration of postoperative fever of > 38°C. CONCLUSIONS: This study showed that younger age at surgery, postoperative IVH volume, and duration of postoperative fever of > 38°C might be risk factors for hydrocephalus after hemispherotomy. The risk of hydrocephalus should be considered in cases of early surgical indication in children. Intraoperative hemostasis and postoperative use of anti-inflammatory measures may reduce the risk of hydrocephalus.

Japanese public health nurses classified based on empathy and secondary traumatic stress: variable-centered and person-centered approaches.

BACKGROUND: Healthcare providers frequently help traumatized people and are regularly exposed to indirect trauma from their work, resulting in negative psychological responses, such as secondary traumatic stress. Empathy has been associated with patient's quality of care and secondary traumatic stress among healthcare providers. However, the relationship between dispositional empathy and secondary traumatic stress has not been fully elucidated. This study used person- and variable-centered approaches to explore the nature of this relationship. METHODS: A total of 1,006 Japanese public health nurses working in the Tohoku region and Saitama prefecture completed questionnaires that included scales assessing dispositional empathy, secondary traumatic stress, and burnout. First, we examined predictors of secondary traumatic stress using multiple linear regression analysis. Then, we conducted a latent profile analysis to classify participants into unique groups based on four subscales of dispositional empathy (i.e., empathic concern, perspective taking, personal distress, fantasy) and secondary traumatic stress. Finally, we compared the mean values of the study variables across these groups. RESULTS: The multiple regression indicated that in those working in Saitama prefecture, lifetime traumatic experiences, work-related distress, and personal distress were positively related to secondary traumatic stress, but perceived support was negatively related to secondary traumatic stress. Latent profile analysis extracted four unique subgroups. Group 1 displayed the highest secondary traumatic stress levels. Group 2 was characterized by the highest level of empathic concern, personal distress, and fantasy and the lowest perspective taking. Group 3 had a moderate secondary traumatic stress level. Group 4 had the lowest secondary traumatic stress and personal distress scores. In these four groups, the burnout scale (exhaustion, cynicism, and professional efficacy) showed a pattern similar to the secondary traumatic stress scale. CONCLUSIONS: Our person-centered approach showed that this sample of public health nurses could be classified into four unique groups based on their empathy and secondary traumatic stress scores. Although this group of public health nurses was not large, one group displayed high personal distress levels and high secondary traumatic stress levels. Further research is needed to determine effective interventions for this group.

Occult Macular Dysfunction Syndrome: Identification of Multiple Pathologies in a Clinical Spectrum of Macular Dysfunction with Normal Fundus in East Asian Patients: EAOMD Report No. 5.

Occult macular dystrophy (OMD) is the most prevalent form of macular dystrophy in East Asia. Beyond RP1L1, causative genes and mechanisms remain largely uncharacterised. This study aimed to delineate the clinical and genetic characteristics of OMD syndrome (OMDS). Patients clinically diagnosed with OMDS in Japan, South Korea, and China were enrolled. The inclusion criteria were as follows: (1) macular dysfunction and (2) normal fundus appearance. Comprehensive clinical evaluation and genetic assessment were performed to identify the disease-causing variants. Clinical parameters were compared among the genotype groups. Seventy-two patients with OMDS from fifty families were included. The causative genes were RP1L1 in forty-seven patients from thirty families (30/50, 60.0%), CRX in two patients from one family (1/50, 2.0%), GUCY2D in two patients from two families (2/50, 4.0%), and no genes were identified in twenty-one patients from seventeen families (17/50, 34.0%). Different severities were observed in terms of disease onset and the prognosis of visual acuity reduction. This multicentre large cohort study furthers our understanding of the phenotypic and genotypic spectra of patients with macular dystrophy and normal fundus. Evidently, OMDS encompasses multiple Mendelian retinal disorders, each representing unique pathologies that dictate their respective severity and prognostic patterns.

Natural history of Becker muscular dystrophy: a multicenter study of 225 patients.

OBJECTIVE: Becker muscular dystrophy (BMD) is a milder variant of Duchenne muscular dystrophy (DMD), a lethal X-linked muscular disorder. Here, we aim to investigat the clinical involvement of skeletal, respiratory, cardiac, and central nervous systems in patients with BMD, as well as genotype-phenotype relationships. METHODS: This nationwide cohort study investigated the clinical manifestations and genotype-phenotype relationships in 225 patients with BMD having in-frame deletion from 22 medical centers. The primary outcome was to elucidate the association of genotype with skeletal muscle, respiratory, cardiac, and central nervous system disorders. Descriptive statistics were used to analyze the data. RESULTS: The average age of the subjects was 31.5 (range, 1-81) years. Initial symptoms of BMD were muscular (60%), followed by asymptomatic hypercreatine kinasemia (32.4%) and central nervous system disorders (5.3%). Gait disturbance was observed in 53.8% of patients and the average age at wheelchair introduction was 36.5 years. The ventilator introduction rate was 6.7% at an average age of 36.6 years. More than 30% of patients had an abnormal electrocardiogram and approximately 15% had heart failure symptoms. Cardiac function on echocardiography varied significantly among the patients. The frequencies of seizures and intellectual/developmental disability were 8.0% and 16.9%, respectively. Exon 45-47deletion (del) was the most common (22.6%), followed by exon 45-48del (13.1%). Patients with exon 45-49del patients demonstrated severe skeletal muscle damage. Patients with exon 45-47del and exon 45-55del patients did not require ventilator use. INTERPRETATION: The study provides important prognostic information for patients and clinicians to establish therapy plans and to implement preventative medicine.

Long-term Observation in Patients with Duchenne Muscular Dystrophy with Early Introduction of a Standing Program Using Knee-ankle-foot Orthoses.

Objectives: This study investigated the outcomes of the early introduction of a standing program for patients with Duchenne muscular dystrophy (DMD). Methods: This was a retrospective observational study of 41 outpatients with DMD aged 15-20 years. We introduced the standing program using knee-ankle-foot orthoses (KAFO) to slow the progression of scoliosis when ankle dorsiflexion became less than 0° in the ambulatory period. Results: Thirty-two patients with DMD were offered the standing program with KAFO; 12 continued the program until the age of 15 years (complete group) and 20 discontinued the program before the age of 15 years (incomplete group). The non-standing program group included 9 patients. The standing program with KAFO was significantly associated with the Cobb angle at the age of 15 years after adjustment for the duration of corticosteroid use and DMD mutation type (P=0.0004). At the age of 15 years, significant correlations were found between the ankle dorsiflexion range of motion (ROM) and non-ambulatory period (P=0.0010), non-ambulatory period and Cobb angle (P<0.0001), Cobb angle and percent predicted forced vital capacity (P=0.0004), and ankle dorsiflexion ROM and Cobb angle (P=0.0066). In the complete group, the age at ambulation loss (log-rank P=0.0015), scoliosis progression (log-rank P=0.0032), and pulmonary dysfunction (log-rank P=0.0006) were significantly higher than in the non-standing program group. Conclusions: The early introduction of a standing program for DMD patients may prolong the ambulation period and slow the progression of scoliosis and pulmonary dysfunction.

Severe Disease Activity May Predispose Patients to Post-colectomy Duodenitis Associated with Ulcerative Colitis.

Objective Diffuse mucosal inflammation in the duodenum, distinct from peptic ulcer disease, has been repeatedly reported in patients with ulcerative colitis (UC). The pathogenesis of this complication remains uncertain; however, colectomy for medically refractory UC appears to trigger duodenitis. Cases in which colectomy was performed for UC were analyzed to characterize UC-related duodenitis after colectomy. Methods A retrospective case-control study of UC-related duodenitis that developed after colectomy in medically refractory UC between January 2011 and June 2020 was conducted. UC-related duodenitis was diagnosed based on typical clinical, endoscopic, and histological findings, and no duodenitis was endoscopically defined by the normal duodenal mucosa. Clinical and laboratory data, disease severity, and medications used were collected and compared between the UC-related and non-duodenitis cases. Results Ten UC-related duodenitis and 35 non-duodenitis cases were identified among 45 patients with UC who underwent esophagogastroduodenoscopy after colectomy. Disease severity, defined by the C-reactive protein level and partial Mayo score prior to colectomy, was significantly higher in duodenitis patients than in non-duodenitis patients. In comparison to non-duodenitis patients, duodenitis patients more frequently received rescue therapies with calcineurin inhibitors or anti-TNF-α agents at the time of colectomy (100% vs. 65.7%). Conclusion Patients with UC with higher disease activity, especially those who require rescue therapies with calcineurin inhibitors and anti-TNF-α agents, may be prone to developing UC-related duodenitis after colectomy.

Morbidity after left trisectionectomy for hepato-biliary malignancies: An analysis of the National Clinical Database of Japan.

BACKGROUND: The aim of this study was to analyze the nationwide surgical outcome of a left trisectionectomy (LT) and to identify the perioperative risk factors associated with its morbidity. METHODS: Cases of LT for hepato-biliary malignancies registered at the Japanese National Clinical Database between 2013 and 2019 were retrospectively reviewed. Statistical analyses were performed to identify the perioperative risk factors associated with a morbidity of Clavien-Dindo classification (CD) ≥III. RESULTS: Left trisectionectomy was performed on 473 and 238 cases of biliary and nonbiliary cancers, respectively. Morbidity of CD ≥III and V occurred in 45% and 5% of cases with biliary cancer, respectively, compared with 26% and 2% of cases with nonbiliary cancer, respectively. In multivariable analyses, biliary cancer was significantly associated with a morbidity of CD ≥III (odds ratio, 1.87; p = .018). In subgroup analyses for biliary cancer, classification of American Society of Anesthesiologists physical status (ASA-PS) 2, portal vein resection (PVR), and intraoperative blood loss ≥30 mL/kg were significantly associated with a morbidity of CD ≥III. CONCLUSIONS: Biliary cancer induces severe morbidity after LT. The ASA-PS classification, PVR, and intraoperative blood loss indicate severe morbidity after LT for biliary cancer.

Influence of surgical volume on the mortality and morbidity of gastrointestinal perforation in children.

PURPOSE: To clarify the influence of surgical volume on the mortality and morbidity of gastrointestinal perforation in children in Japan. METHODS: We collected data on pediatric patients with gastrointestinal perforation between 2017 and 2019, from the National Clinical Database. The surgical volumes of various institutions were classified into three groups: low (average number of surgeries for gastrointestinal perforation/year < 1), medium (≥ 1, < 6), and high (≥ 6). The observed-to-expected (o/e) ratios of 30-day mortality and morbidity were calculated for each group using an existing risk model. RESULTS: Among 1641 patients (median age, 0.0 years), the 30-day mortality and morbidity rates were 5.2% and 37.7%, respectively. The 30-day mortality rates in the low-, medium-, and high-volume institutions were 4.9%, 5.3%, and 5.1% (p = 0.94), and the 30-day morbidity rates in the three groups were 26.8%, 39.7%, and 37.7% (p < 0.01), respectively. The o/e ratios of 30-day mortality were 1.05 (95% confidence interval [CI] 0.83-1.26), 1.08 (95% CI 1.01-1.15), and 1.02 (95% CI 0.91-1.13), and those of 30-day morbidity were 1.72 (95% CI 0.93-2.51), 1.03 (95% CI 0.79-1.28), and 0.95 (95% CI 0.56-1.33), respectively. CONCLUSION: Surgical volume does not have significant impact on the outcomes of pediatric gastrointestinal perforation in Japan.

Trends in the effect of COVID-19 on consultations for persons with clinical and subclinical eating disorders.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has increased the risk of individuals developing eating disorders and has exacerbated existing eating disorders. This observational study investigated the impact of the COVID-19 pandemic on patients with clinical and subclinical eating disorders. METHODS: This study was conducted over a period of four years: two years before and after the onset of the COVID-19 pandemic in Japan. We recorded the number and types of consultations provided by the Eating Disorder Treatment and Support Center coordinator. For subgroup analysis, data were classified by age, body mass index, and source of consultation, including patients, families, and personnel. The Seasonal Decomposition of Time Series by Loess was used for time series analysis. RESULTS: The total number of consultations increased after the start of the pandemic and peaked around the beginning of 2022, before subsequently falling despite the increase in the number of COVID-19 infections. A similar trend was observed in patients aged 10-29 years. The study period coincided with social isolation and school/college/university closures. CONCLUSIONS: The number of eating disorder consultations increased after the start of the pandemic. Although COVID-19 infections persisted, the pandemic's impact was transient.

Future perspective of psychiatric home-visit nursing provided by nursing stations in Japan.

Psychiatric home-visit nursing supports the lives of people with mental disorders in the community and plays an important role in the "community-based integrated care system" which is rapidly being implemented in Japan. Although the number of responsive home-visit nursing stations (HVNS) is increasing, the current situation of service provision has not yet been clarified. This study aimed to investigate the characteristics and difficulties of psychiatric home-visit nursing provided by HVNS. We further discussed future care provisions and service improvements. We conducted a questionnaire survey of 7,869 member stations of the National Association for Visiting Nurse Service; of this number 2,782 facilities (35.4%) responded. Of the 2,782 facilities, 1,613 (58.0%) provided psychiatric home-visit nursing. The HVNS that provided psychiatric home-visit nursing were diverse, and the percentage of users with mental disorders ranged widely. Majority of the HVNS reported having "difficulty in caring for users/families who refuse care" (56.3%), "difficulty in care for psychiatric symptoms" (54.0%), and "difficulty in assessment of psychiatric symptoms" (49.1%), with differences in difficulty depending on the percentage of psychiatric users. As user needs and HVNS characteristics diversify, it is necessary to take advantage of the characteristics of each station to develop consultation and training systems and collaborative network platforms within each community for future sustainable service provision.

Service contents and recovery orientation of psychiatric home-visit nursing evaluated by users in Japan.

The aim of this study was to clarify the differences perceived by users of home-visit nursing care between providers from medical institutions and services from independent home-visit nursing stations, as well as to examine the recovery orientation from the perspectives of the users. We conducted a questionnaire survey of 32 home-visit nursing stations and 18 medical institutions. From these facilities, 10 users of psychiatric home-visit nursing services who were being treated for schizophrenia and bipolar disorder were selected. With regard to the care that they thought was good, the home-visit nursing station users responded more often than users of home-visit nursing care provided by medical institutions regarding "help with hobbies and fun" and "support to empower you". Regarding what users wanted from home-visit nursing care, a statistically significant difference was found between users of home nursing stations who answered, "I want the same person to come", and users of home-visit nursing services provided by medical institutions, who answered, "I want various people to come". Brief INSPIRE-J score for study participants was 81.9 (standard deviation; SD 18.1) for users of home-visit nursing care services from medical institutions and 83.7 (SD 15.5) for home-visit nursing station users. It is conceivable that the care provided by psychiatric home-visit nursing services may have a greater potential for promoting recovery. However, since the characteristics of users and facilities may differ, future research is needed to clarify which recovery factors are effectively promoted by each service.

Identifying factors related to stigma toward psychiatric illness and mental health services and attitudes of help-seeking among Japan Ground Self-Defense Force members.

The stigma that military personnel feel toward mental illness and mental healthcare hinders their access to mental health services. Stigma is influenced by culture-specifically, that held by military personnel is closely related to military culture. To our knowledge, this is the first large-scale investigation aimed at identifying the factors, including demographic factors and elements of military culture, related to stigma among members of the Japan Ground Self-Defense Force. An anonymous questionnaire was administered to 4754 members. The questionnaire included items regarding demographic factors, history of psychiatric visits, military rank, overseas deployment experience, disaster relief experience, supervisor leadership, unit cohesion, general psychological distress, stigma toward perceived mental illness, and attitudes toward help-seeking. Multiple regression analysis was used to identify the various factors related to stigma. Responses were obtained from 4305 (90.5%) participants, among which 3723 (78.3%) were valid. Multiple regression analyses revealed that a variety of factors including age, psychiatric consultation, leadership, and cohesiveness were markedly associated with stigma and attitudes toward help-seeking. This study revealed that various factors including demographic factors and military culture factors such as supervisor leadership and unit cohesion are related to stigma and attitudes toward mental health services among Japan Ground Self-Defense Force personnel. Further studies are needed to examine the results in depth.

Updating the Predictive Models for Mortality and Morbidity after Low Anterior Resection Based on the National Clinical Database.

INTRODUCTION: We previously developed risk models for mortality and morbidity after low anterior resection using a nationwide Japanese database. However, the milieu of low anterior resection in Japan has undergone drastic changes since then. This study aimed to construct risk models for 6 short-term postoperative outcomes after low anterior resection, i.e., in-hospital mortality, 30-day mortality, anastomotic leakage, surgical site infection except for anastomotic leakage, overall postoperative complication rate, and 30-day reoperation rate. METHODS: This study enrolled 120,912 patients registered with the National Clinical Database, who underwent low anterior resection between 2014 and 2019. Multiple logistic regression analyses were performed to generate predictive models of mortality and morbidity using preoperative information, including the TNM stage. RESULTS: We developed new risk prediction models for the overall postoperative complication and 30-day reoperation rates for low anterior resection, which were absent from the previous version. The concordance indices for each endpoint were 0.82 for in-hospital mortality, 0.79 for 30-day mortality, 0.64 for anastomotic leakage, 0.62 for surgical site infection besides anastomotic leakage, 0.63 for complications, and 0.62 for reoperation. The concordance indices of all four models included in the previous version showed improvement. CONCLUSION: This study successfully updated the risk calculators for predicting mortality and morbidity after low anterior resection using a model based on vast nationwide Japanese data.
