Importance

Substantial heterogeneity exists in treatment recommendations across molecular tumor boards (MTBs), especially for biomarkers with low evidence levels; therefore, the learning program is essential.

Objective

To determine whether a learning program sharing treatment recommendations for biomarkers with low evidence levels contributes to the standardization of MTBs and to investigate the efficacy of an artificial intelligence (AI)–based annotation system.

Design, Setting, and Participants

This prospective quality improvement study used 50 simulated cases to assess concordance of treatment recommendations between a central committee and participants. Forty-seven participants applied from April 7 to May 13, 2021. Fifty simulated cases were randomly divided into prelearning and postlearning evaluation groups to assess similar concordance based on previous investigations. Participants included MTBs at hub hospitals, treating physicians at core hospitals, and AI systems. Each participant made treatment recommendations for each prelearning case from registration to June 30, 2021; participated in the learning program on July 18, 2021; and made treatment recommendations for each postlearning case from August 3 to September 30, 2021. Data were analyzed from September 2 to December 10, 2021.

Exposures

The learning program shared the methodology of making appropriate treatment recommendations, especially for biomarkers with low evidence levels.

Main Outcomes and Measures

The primary end point was the proportion of MTBs that met prespecified accreditation criteria for postlearning evaluations (approximately 90% concordance with high evidence levels and approximately 40% with low evidence levels). Key secondary end points were chronological enhancements in the concordance of treatment recommendations on postlearning evaluations from prelearning evaluations. Concordance of treatment recommendations by an AI system was an exploratory end point.

Results

Of the 47 participants who applied, 42 were eligible. The accreditation rate of the MTBs was 55.6% (95% CI, 35.3%-74.5%; P < .001). Concordance in MTBs increased from 58.7% (95% CI, 52.8%-64.4%) to 67.9% (95% CI, 61.0%-74.1%) (odds ratio, 1.40 [95% CI, 1.06-1.86]; P = .02). In postlearning evaluations, the concordance of treatment recommendations by the AI system was significantly higher than that of MTBs (88.0% [95% CI, 68.7%-96.1%]; P = .03).

Conclusions and Relevance

The findings of this quality improvement study suggest that use of a learning program improved the concordance of treatment recommendations provided by MTBs to central ones. Treatment recommendations made by an AI system showed higher concordance than that for MTBs, indicating the potential clinical utility of the AI system.

Objective:

The aim of the present randomized controlled trial was to evaluate the superiority of indocyanine green fluorescence imaging (ICG-FI) in reducing the rate of anastomotic leakage in minimally invasive rectal cancer surgery.

Background:

The role of ICG-FI in anastomotic leakage in minimally invasive rectal cancer surgery is controversial according to the published literature.

Methods:

This randomized, open-label, phase 3, trial was performed at 41 hospitals in Japan. Patients with clinically stage 0–III rectal carcinoma less than 12 cm from the anal verge, scheduled for minimally invasive sphincter-preserving surgery were preoperatively randomly assigned to receive a blood flow evaluation by ICG-FI (ICG+ group) or no blood flow evaluation by ICG-FI (ICG− group). The primary endpoint was the anastomotic leakage rate (grade A+B+C, expected reduction rate of 6%) analyzed in the modified intention-to-treat population.

Results:

Between December 2018 and February 2021, a total of 850 patients were enrolled and randomized. After the exclusion of 11 patients, 839 were subject to the modified intention-to-treat population (422 in the ICG+ group and 417 in the ICG− group). The rate of anastomotic leakage (grade A+B+C) was significantly lower in the ICG+ group (7.6%) than in the ICG− group (11.8%) (relative risk, 0.645; 95% confidence interval 0.422–0.987; P=0.041). The rate of anastomotic leakage (grade B+C) was 4.7% in the ICG+ group and 8.2% in the ICG− group (P=0.044), and the respective reoperation rates were 0.5% and 2.4% (P=0.021).

Conclusions:

Although the actual reduction rate of anastomotic leakage in the ICG+ group was lower than the expected reduction rate and ICG-FI was not superior to white light, ICG-FI significantly reduced the anastomotic leakage rate by 4.2%.

There are no validated biomarkers for schizophrenia (SCZ), a disorder linked to neural network dysfunction. We demonstrate that collapsin response mediator protein-2 (CRMP2), a master regulator of cytoskeleton and, hence, neural circuitry, may form the basis for a biomarker because its activity is uniquely imbalanced in SCZ patients. CRMP2's activity depends upon its phosphorylation state. While an equilibrium between inactive (phosphorylated) and active (nonphosphorylated) CRMP2 is present in unaffected individuals, we show that SCZ patients are characterized by excess active CRMP2. We examined CRMP2 levels first in postmortem brains (correlated with neuronal morphometrics) and then, because CRMP2 is expressed in lymphocytes as well, in the peripheral blood of SCZ patients versus age-matched unaffected controls. In the brains and, more starkly, in the lymphocytes of SCZ patients <40 y old, we observed that nonphosphorylated CRMP2 was higher than in controls, while phosphorylated CRMP2 remained unchanged from control. In the brain, these changes were associated with dendritic structural abnormalities. The abundance of active CRMP2 with insufficient opposing inactive p-CRMP2 yielded a unique lowering of the p-CRMP2:CRMP2 ratio in SCZ patients, implying a disruption in the normal equilibrium between active and inactive CRMP2. These clinical data suggest that measuring CRMP2 and p-CRMP2 in peripheral blood might reflect intracerebral processes and suggest a rapid, minimally invasive, sensitive, and specific adjunctive diagnostic aid for early SCZ: increased CRMP2 or a decreased p-CRMP2:CRMP2 ratio may help cinch the diagnosis in a newly presenting young patient suspected of SCZ (versus such mimics as mania in bipolar disorder, where the ratio is high).

ABSTRACT

Objective

BONENAVI is a software designed to automatically calculate the automated bone scan index (aBSI) and quantify the number of bone metastases on bone scans. We conducted an investigator‐initiated prospective study using BONENAVI to evaluate its prognostic utility for metastatic castration‐sensitive prostate cancer (mCSPC).

Methods

Eligible patients were assigned to one of two treatment groups: androgen deprivation therapy (ADT) combined with abiraterone acetate and prednisolone (AA group) or ADT alone (ADT group). The primary objective was to evaluate the prognostic value of the median aBSI in predicting progression‐free survival (PFS) in the AA group. Secondary objectives included assessing the prognostic value of the median aBSI for PFS across all patients and the ADT group, as well as evaluating the prognostic utility of the aCHAARTED classifications based on BONENAVI.

Results

The median aBSI was not significantly associated with PFS in the AA group, the ADT group, or the overall patient cohort. Patients with aCHAARTED high‐volume disease (HVD) exhibited worse PFS than those with low‐volume disease (LVD) in the overall cohort and AA group; however, these differences were not statistically significant. In contrast, patients with aCHAARTED HVD in the ADT group had significantly worse PFS than those with LVD.

Conclusion

The median aBSI could not predict the prognosis of patients with mCSPC. However, the aCHAARTED classification derived from BONENAVI may provide valuable insights for predicting PFS in patients with mCSPC undergoing ADT.

BACKGROUND AND AIM: Qualitative diagnosis of ulcerative colitis-associated neoplasia (UCAN) is crucial for surveillance colonoscopy in patients with ulcerative colitis (UC). Although the utility of magnifying endoscopy with narrow-band imaging (ME-NBI) in sporadic neoplasia diagnosis has been reported, its efficacy in UCAN remains unclear. This study aimed to evaluate the usefulness of ME-NBI for qualitative diagnosis of UCAN. METHODS: We generated 60 ME-NBI images (30 UCANs and 30 nonneoplasia lesions, including 10 polypoid and 20 nonpolypoid lesions) from patients with UC who underwent colonoscopy at our hospital between 2015 and 2023. Eleven endoscopists (seven experts and four trainees) independently assessed these images. Lesions were categorized into high- (≥ 80%), moderate- (50%-79%), and low- (< 50%) accuracy groups on the basis of the correct diagnostic rate. RESULTS: Overall sensitivity, specificity, and correct diagnostic rates were 66.5%, 79.0%, and 71.8%, respectively. Experts tended to exhibit higher specificity than trainees (83% vs. 70%). Polypoid lesions showed higher sensitivity (92% vs. 54%) and lower specificity (61% vs. 88%) than nonpolypoid lesions. Overall, the kappa value was 0.411. In UCAN, 37%, 37%, and 24% were classified into the high-, moderate-, and low-accuracy groups, respectively. All endoscopists assessed one case of UCAN in the low-accuracy group as a nonneoplastic vessel with a surface pattern. Only two nonneoplasias were identified as having nonneoplastic vessel and surface patterns by all endoscopists. CONCLUSIONS: This study demonstrated the usefulness of ME-NBI for qualitative diagnosis, along with its limitations. A unique endoscopic diagnostic algorithm for UCAN, incorporating ME-NBI and other modalities, is necessary.

AIM: Lymph node metastasis is an adverse prognostic factor in pancreatic ductal adenocarcinoma. However, it remains a challenge to predict lymph node metastasis using preoperative imaging alone. We used machine learning (combining preoperative imaging findings, tumor markers, and clinical information) to create a novel prediction model for lymph node metastasis in resectable pancreatic ductal adenocarcinoma. METHODS: The data of patients with resectable pancreatic ductal adenocarcinoma who underwent surgery between September 1991 and October 2022 were retrospectively examined. Machine-learning software (Statistical Package for the Social Sciences Modeler) was used to create a prediction model, and parameter tuning was performed to improve the model's accuracy. We also analyzed the contribution of each feature to prediction using individual conditional expectation and partial dependence plots. RESULTS: Of the 331 cases included in the study, 241 comprised the training cohort and 90 comprised the test cohort. After parameter tuning, the areas under the receiver operating characteristic curves for the training and test cohorts were 0.780 and 0.795, respectively. Individual conditional expectation and partial dependence plots showed that larger tumor size and carbohydrate antigen 19-9 and Duke pancreatic monoclonal antigen type 2 levels were associated with positive lymph node metastasis prediction in this model; neoadjuvant treatment was associated with negative lymph node metastasis prediction. CONCLUSION: Machine learning may contribute to the creation of an effective predictive model of lymph node metastasis in pancreatic ductal adenocarcinoma. Prediction models using machine learning may contribute to the development of new treatment strategies in resectable pancreatic ductal adenocarcinoma.

Introduction: In Japan, telemedicine has gradually expanded due to deregulation in response to the COVID-19 pandemic. However, its current status remains unclear, as it is primarily provided by general practitioners. This study aims to examine the use of telemedicine in sublingual immunotherapy (SLIT) for patients with Japanese cedar pollen allergy and/or house dust mite allergic rhinitis. Methods: We conducted a retrospective analysis of medical record data from seven otorhinolaryngology clinics and performed an exploratory evaluation between a group that combined telemedicine and in-person visits during the initial 6 months of SLIT and another group with only in-person visits. Results: Following propensity score matching, 51 and 82 patients were eligible for the telemedicine and in-person groups, respectively, with 33 cases in both groups. Both groups had similar characteristics after matching. No significant difference was found in the withdrawal rate at 6 months from the start of SLIT (6.1% and 9.1% in each group; p = 1.00), side effects, or treatment efficacy between the two groups. The average copayment for patients tended to be significantly higher in the telemedicine group after one, three, and 6 months following SLIT initiation. Discussion: The situation of patients who receive an appropriate combination of telemedicine and in-person visits is not significantly different from patients who receive in-person visits alone. This study may help indicate the actual status of telemedicine in Japan. Further investigation at more facilities is necessary in the future to dispel concerns in the practice setting.

Objective

Cervical cancer screening rates are low in Japan. Therefore, when a woman is pregnant, this is a good opportunity to visit an obstetrics and gynecology clinic to have cervical cytology. This study aimed to clarify the association between cervical cancer screening and the management of pregnant women’s health.

Methods

We prospectively examined the relationships between cervical cytological results during prenatal checkups and the following factors: participant’s background, cytological sampling instruments, and awareness of cytological results.

Results

Of the 2725 participants, 71 showed abnormal results defined as atypical squamous cells of undetermined significance or higher grade (ASC-US⁺). ASC-US⁺ detection rates were higher in smokers, younger participants, those with a low education, those without cancer screening in the past 2 years, and those who received cytology using a spatula or brush. A multivariable logistic regression analysis identified smoking (adjusted odds ratio: 2.99 [95% confidence interval: 1.41–6.33]) and a spatula/brush (adjusted odds ratio: 2.46 [95% confidence interval: 1.09–5.53]) as independent variables associated with detecting ASC-US⁺. Among the participants, 39.4% (28/71) self-reported “no abnormalities,” despite obtaining an ASC-US⁺ result.

Conclusions

Pre-pregnancy smoking and cytological sampling tools may contribute to detecting ASC-US⁺. Patients with detected abnormalities need accurate information and reliable follow-up.

BACKGROUND: Anti-SS-A/Ro antibody (anti-SSA), the diagnostic marker of Sjögren's syndrome (SS), is often detected in systemic sclerosis (SSc). Some patients are diagnosed with SSc/SS overlap syndromes, while there are anti-SSA-positive SSc cases without SS. In this study, we investigated the clinical characteristics of SSc with anti-SSA and clarified the clinical impact of this antibody in SSc. METHODS: A retrospective chart review was conducted of 156 patients with SSc at Yokohama City University Hospital from 2018 to 2021. Clinical data, laboratory data, imaging, and autoantibody positivity status were collected and analysed to assess the association between these variables and anti-SSA using multivariable logistic regression analysis. RESULTS: This cohort included 18 men and 138 women with SSc (median age, 69.0 years). Thirty-nine patients had diffuse cutaneous SSc (dcSSc) (25%), and 117 patients had limited cutaneous SSc (75%). Forty-four patients were anti-SSA-positive. Among them, 24 fulfilled the SS criteria. Multivariable logistic regression revealed that anti-SSA was statistically associated with interstitial lung disease (ILD; odds ratio [OR] = 2.67; 95% confidence interval [CI], 1.14-6.3; P = 0.024). Meanwhile, anti-SSA positivity tended to increase the development of digital ulcer (OR = 2.18; 95% CI, 0.99-4.82, P = 0.054). In the comparative analysis of the autoantibody single-positive and anti-SSA/SSc-specific autoantibody double-positive groups, the anti-SSA single-positive group showed a significantly increased risk of ILD (OR = 12.1; 95% CI, 2.13-140.57; P = 0.003). Furthermore, patients with SSc and anti-SSA indicated that anti-SSA-positive SSc without SS was strongly associated with dcSSc when compared to that in patients with SS (OR = 6.45; 95% CI, 1.23-32.60; P = 0.024). CONCLUSIONS: Anti-SSA positivity increases the risk of organ involvement, such as ILD, in patients with SSc. Additionally, the anti-SSA-positive SSc without SS population may have more severe skin fibrosis than others. Anti-SSA may be a potential marker of ILD and skin severity in SSc.

BACKGROUND: This study investigated whether the chronic use of adaptive servo-ventilation (ASV) reduces all-cause mortality and the rate of urgent rehospitalization in patients with heart failure (HF). METHODS AND RESULTS: This multicenter prospective observational study enrolled patients hospitalized for HF in Japan between 2019 and 2020 who were treated either with or without ASV therapy. Of 845 patients, 110 (13%) received chronic ASV at hospital discharge. The primary outcome was a composite of all-cause death and urgent rehospitalization for HF, and was observed in 272 patients over a 1-year follow-up. Following 1:3 sequential propensity score matching, 384 patients were included in the subsequent analysis. The median time to the primary outcome was significantly shorter in the ASV than in non-ASV group (19.7 vs. 34.4 weeks; P=0.013). In contrast, there was no significant difference in the all-cause mortality event-free rate between the 2 groups. CONCLUSIONS: Chronic use of ASV did not impact all-cause mortality in patients experiencing recurrent admissions for HF.

AIM: Peripheral artery disease (PAD) severely impairs patient prognosis and quality of life (QOL). Although lipoprotein apheresis (LA) has been applied to patients with PAD and elevated serum atherogenic lipoproteins, we hypothesized that LA can be effective for treating PAD even in patients with controlled serum lipoproteins through pleiotropic anti-atherosclerotic effects beyond lipoprotein removal. This study aimed to evaluate the efficacy of LA in patients with treatment-resistant PAD and controlled serum lipoproteins focusing on QOL. METHODS: In a single-arm prospective study, 30 patients with refractory PAD who had controlled serum lipoproteins underwent sequential LA sessions using dextran sulfate adsorption columns, aiming to complete 10 sessions. The ankle-brachial pressure index (ABI) and vascular QOL (VascuQOL) score were evaluated as the primary outcomes. Secondary outcomes included reactive hyperemia index (RHI) and biological antioxidant potential (BAP) as an endothelial function test and serum antioxidative-capacity evaluation, respectively. RESULTS: ABI significantly increased after LA sessions (pre-treatment 0.60±0.09 vs. post-treatment 0.65±0.13, p=0.023). Total VascuQOL score (3.7±1.1 vs 4.6±1.1, p＜0.001) and RHI (1.70±0.74 vs 2.34±1.76, p=0.023) significantly improved after the LA sessions. BAP tended to increase after the LA sessions, and the change reached statistical significance 3 months after treatment. CONCLUSION: ABI and QOL improved after a series of LA sessions in conventional treatment-resistant PAD patients with controlled serum lipoprotein levels. Increased antioxidative capacity and ameliorated endothelial function were observed after the LA treatment.

Abstract

Serum heme oxygenase (HO)-1 level has been reported as a clinically reliable diagnostic biomarker for acute exacerbation of interstitial lung disease (ILD); however, its utility for predicting mortality among these patients is unclear. Serum HO-1 levels of patients newly diagnosed with acute exacerbation of ILD were measured at the time of initiating steroid pulse therapy. The relationship between serum HO-1 and various other serum biomarkers, change in HRCT findings, and disease prognosis at 12 weeks after diagnosis of acute exacerbation was evaluated in 51 patients, of whom 17 (33%) had idiopathic pulmonary fibrosis (IPF). Serum HO-1 was higher in patients with acute exacerbation of IPF than in patients with acute exacerbation of other ILDs. Serum HO-1 levels were higher in patients who died within these 12 weeks than in survivors. Among age, sex, comorbidities, IPF diagnosis, HRCT findings, and blood biomarkers, serum HO-1 was a primary predictor of 12-week mortality. In 41 patients who underwent repeat HRCT, serum HO-1 was higher in patients with honeycomb progression than in those without. Serum HO-1 measurement could be useful for evaluating disease mortality and morbidity of patients with acute exacerbation of ILDs.

Introduction: This study aimed to identify immune mediators, including cytokines, chemokines, and growth factors, in the plasma for predicting treatment efficacy and immune-related adverse events (irAEs) in advanced urothelial carcinoma (aUC) treated with immune checkpoint inhibitors (ICIs).

Methods: We enrolled 57 patients with aUC who were treated with the anti-programmed cell death protein 1 (PD-1) antibody pembrolizumab after the failure of platinum-based chemotherapy between February 2018 and December 2020. Plasma levels of 73 soluble immune mediators were measured before and 6 weeks after initiating pembrolizumab therapy. The association of estimated soluble immune mediators with clinical outcomes, including overall survival (OS), progression-free survival (PFS), anti-tumor responses, and irAEs, were statistically evaluated.

Results: In the multivariate analysis, levels of 18 factors at baseline and 12 factors during treatment were significantly associated with OS. Regarding PFS, baseline levels of 17 factors were significantly associated with PFS. Higher levels of interleukin (IL)-6, IL-8, soluble tumor necrosis factor receptor 1 (sTNF-R1), and IL-12 (p40), both at baseline and post-treatment, were significantly associated with worse OS. Conversely, low IL-6 and high TWEAK levels at baseline were associated with irAEs. Among identified factors, interferon (IFN) γ and IL-12 (p40) were repeatedly identified; high baseline levels of these factors were risk factors for worse OS and PFS, as well as progressive disease. Notably, using correlation and principal component analysis, factors significantly associated with clinical outcomes were broadly classified into three groups exhibiting similar expression patterns.

Discussion: Measuring plasma levels of soluble immune mediators, such as IL-6, IL-8, sTNF-R1, IFNγ, and IL-12 (p40), could be recommended for predicting prognosis and irAEs in ICI-treated patients with aUC.

Objectives

Infection is a leading cause of death in patients with systemic lupus erythematosus (SLE). Alt hough hydroxychloroquine (HCQ) has been reported to inhibit infection, evidence from Asian populations remains insufficient. We investigated this effect in Japanese SLE patients.

Methods

Data from the Lupus Registry of Nationwide Institutions were used in this study. The patients were ≥20 years old and met the American College of Rheumatology (ACR) classification criteria revised in 1997. We defined “severe infections” as those requiring hospitalization. We analyzed the HCQ’s effect on infection suppression using a generalized estimating equation (GEE) logistic regression model as the primary endpoint and performed a survival analysis for the duration until the first severe infection.

Results

Data from 925 patients were used (median age, 45 [interquartile range 35–57] years; female, 88.1%). GEE analysis revealed that severe infections were significantly associated with glucocorticoid dose (odds ratio [OR] 1.968 [95% confidence interval, 1.379–2.810], p&amp;lt;0.001), immunosuppressants (OR 1.561 [1.025–2.380], p=0.038), and baseline age (OR 1.043 [1.027–1.060], p&amp;lt;0.001). HCQ tended to suppress severe infections, although not significantly (OR 0.590 [0.329–1.058], p=0.077). Survival time analysis revealed a lower incidence of severe infections in the HCQ group than in the non-HCQ group (p&amp;lt;0.001). In a Cox proportional hazards model, baseline age (hazard ratio [HR] 1.029 [1.009–1.050], p=0.005) and HCQ (HR 0.322 [0.142–0.728], p=0.006) were significantly related to incidence.

Conclusion

HCQ may help extend the time until the occurrence of infection complications and tends to decrease infection rates.

Acute exacerbation (AE) of interstitial pneumonia (IP) shows poor prognosis, due to the typical histological pattern of diffuse alveolar damage superimposed upon lung fibrosis. The previous reports comparing clinical features between AE of idiopathic interstitial pneumonias (IIPs) and those of IPs with known etiology are limited. We retrospectively compared clinical parameters including age, sex, Charlson Comorbidity Index score (CCIS), blood biomarkers at diagnosis of AE, treatment, and 3-month mortality between patients with AE of IIPs and collagen vascular disease-associated interstitial pneumonia (CVD-IP). We assessed 85 patients, comprising 66 patients with AE of IIPs (78%) and 19 patients with AE of CVD-IP (22%). The least absolute shrinkage and selection operator regression selected CCIS (hazard ratio, 1.281; 95% confidence interval, 1.055-1.556; P = 0.012) and log serum lactate dehydrogenase (LDH) (hazard ratio, 6.267; 95% confidence interval, 2.172-18.085; P < 0.001) as significant predictors of 3-month mortality among these patients. Also, the adjusted survival curves using sex, CCIS, and serum LDH showed no significant differences between these two groups. In conclusion, among AE patients, CCIS and serum LDH level may be more important prognostic factors for 3-month mortality rather than two classification of IP subtypes: IIPs and CVD-IP.

The relationship between epidermal growth factor receptor tyrosine kinase inhibitor (EGFR‐TKI) resistance, including osimertinib, and programmed cell death‐ligand 1 (PD‐L1) expression status in EGFR‐mutated non‐small cell lung carcinoma (NSCLC) remains unclear.

Patients and Methods

We retrospectively analyzed 64 patients with unresectable advanced or metastatic NSCLC carrying EGFR exon 19 deletions (ex19del) or EGFR exon 21 L858R substitutions (L858R) who received osimertinib as the first‐line treatment. We compared progression‐free survival (PFS) between eligible patients with PD‐L1 tumor proportion scores (TPS) ≥20% and PD‐L1 TPS &lt;20% using the Kaplan–Meier survival plots with a log‐rank test. Multivariate analysis was performed to examine the poor prognostic factors of PFS.

Results

The PD‐L1 TPS ≥20% group included 22 cases (median [range] age: 70.5 [33–86] years; 10 women [45.5%]; 11 current or ex‐smokers [50%]); ECOG performance status (PS) of 0–1/2/3/4 was noted in 16/4/1/1 patients, respectively. The PD‐L1 TPS &lt;20% group included 42 patients (median [range] age 73 [43–88] years; 29 women [69%]; 12 current or ex‐smokers [28.6%]); ECOG PS of 0–1/2/3/4 was noted in 33/6/3/0 cases, respectively. The median PFS was 9.1 and 28.1 months in the PD‐L1 TPS ≥20% and PD‐L1 TPS &lt;20% groups, respectively (log‐rank p = 0.013). Multivariate analysis revealed that PD‐L1 TPS ≥20% was associated with PFS (hazard ratio: 2.35, 95% confidence interval: 1.09–5.08, p = 0.030).

Conclusion

PD‐L1 TPS ≥20% in patients with EGFR‐mutated NSCLC may be associated with early resistance to osimertinib.

Objectives

Severe submucosal fibrosis is a crucial technical difficulty encountered during endoscopic submucosal dissection (ESD) in patients with ulcerative colitis (UC). We aimed to identify predictors of severe submucosal fibrosis in patients with UC.

Methods

We retrospectively included 55 tumors resected using ESD from 48 consecutive patients with UC. We analyzed the clinicopathological characteristics and treatment outcomes between the F0/1 (none to mild submucosal fibrosis) group (n = 28) and F2 (severe submucosal fibrosis) group (n = 27).

Results

No significant difference was found between the F0/1 and F2 groups in en bloc resection rate (100% vs. 96%, P = 0.49), the R0 resection rate (100% vs. 93%, P = 0.24), and the dissection speed (0.18 vs. 0.13 cm²/min, P = 0.07). Intraoperative perforation was more common in the F2 group (30%) than in the F0/1 group (8%; P = 0.01). Multivariable analysis showed that a longer duration of UC (≥10 years; odds ratio [OR] 6.11; 95% confidence interval [CI] 1.20–31.03; P = 0.03) and scarring of background mucosa of the tumor (OR 39.61; 95% CI 3.91–400.78; P &lt; 0.01) were independent predictors of severe submucosal fibrosis.

Conclusion

Long UC duration and scarring background mucosa were predictors of severe submucosal fibrosis associated with perforation during ESD.

Abstract

Introduction

Conventionally, the recommended duration of adjuvant chemotherapy of colon cancer had been 6 months. The IDEA Collaboration suggested that shortening capecitabin and oxaliplatin (CAPOX) adjuvant chemotherapy may be possible. S‐1 and oxaliplatin (SOX) treatment is standard treatment in metastatic colorectal cancer in Japan. The aim of this study was to optimize treatment dosage and duration of adjuvant SOX in stage III colon cancer.

Methods

This trial was as open‐label multi‐center randomized phase II study. Patients with stage III colon cancer were randomly assigned to 3 months or 6 months of adjuvant SOX treatment in different doses: 130 mg/m² (3 months) or 100 mg/m² (6 months) of oxaliplatin. The primary endpoint was 3‐year disease‐free survival (DFS) and the null hypothesis for the primary endpoint was that the 3‐year DFS was ≤72% in each arm and was tested with a one‐sided significance level of 10%.

Results

Eighty‐two patients were assigned to the 6 months arm and 81 to the 3 months arm. The 3‐year DFS was 75.0% (80% CI 67.95–80.72, p = 0.282) in the 6 months arm and 76.9% (80% CI 70.1–82.38, p = 0.171) in the 3 months arm. Treatment completion rate and relative dose intensity (RDI) were higher in 3 months than 6 months arm. The adverse events (AE) were similar in both arms.

Conclusions

The 3‐year DFS was not significantly superior to null hypothesis in both 3 months and 6 months arms for the stage III colon cancer. Primary endpoint was not achieved. The SOX regimen was not feasible in long‐term outcomes.

Abstract

Background

Despite the widespread availability of medication choices for metastatic castration-resistant prostate cancer (mCRPC), biomarkers to predict the efficacy of each mCRPC treatment have not yet been established. This study developed a prognostic nomogram and a calculator to predict the prognosis of patients with mCRPC who received abiraterone acetate (ABI) and/or enzalutamide (ENZ).

Methods

In total, 568 patients with mCRPC who underwent ABI and/or ENZ between 2012 and 2017 were enrolled. A prognostic nomogram based on the risk factors was developed using the Cox proportional hazards regression model and clinically important factors. The discriminatory ability of the nomogram was assessed according to the concordance index (C-index). A 5-fold cross-validation was repeated 2000 times to estimate the C-index, and the means of the estimated C-index for the training and validation sets were determined. A calculator based on this nomogram was then developed.

Results

The median overall survival (OS) was 24.7 months. Multivariate analysis showed that the time to CRPC, pre-chemotherapy, baseline prostate-specific antigen, baseline alkaline phosphatase, and baseline lactate dehydrogenase levels were independent risk factors for OS (hazard ratio [HR]: 0.521, 1.681, 1.439, 1.827, and 12.123, p = 0.001, 0.001,  &lt; 0.001, 0.019, and  &lt; 0.001, respectively). The C-index was 0.72 in the training cohort and 0.71 in the validation cohort.

Conclusions

We developed a nomogram and calculator to predict OS in Japanese patients with mCRPC who received ABI and/or ENZ. Reproducible prognostic prediction calculators for mCRPC will facilitate greater accessibility for clinical use.

Background. The ILD-GAP scoring system has been widely used to predict the prognosis of patients with interstitial lung disease (ILD). The ability of the ILD-GAP scoring system combined with the Charlson Comorbidity Index score (CCIS) (ILD-GAPC) to predict ILD prognosis was investigated. Methods. In ILD patients, including idiopathic pulmonary fibrosis (IPF), idiopathic nonspecific interstitial pneumonia (iNSIP), collagen vascular disease-related interstitial pneumonia (CVD-IP), chronic hypersensitivity pneumonitis (CHP), and unclassifiable ILD (UC-ILD), treated between April 2013 and April 2017, the relationships between baseline clinical parameters, including age, sex, CCIS, ILD diagnosis, pulmonary function test results, and disease outcomes, were retrospectively assessed, and the ability to predict prognosis was compared between the ILD-GAP and ILD-GAPC models, respectively. Results. A total of 185 patients (mean age, 71.9 years), all of whom underwent pulmonary function testing, including percentage predicted diffusion capacity for carbon monoxide, were assessed. ILD diagnosis consisted of IPF in 57 cases, iNSIP and CVD-IP in 117 cases, CHP in 6 cases, and UC-ILD in 5 cases. The ILD-GAPC provided a greater area under the receiver operating characteristic curve (0.758) for predicting 3-year ILD-related events than the ILD-GAP (0.721). In addition, log-rank tests showed that the Kaplan−Meier curves differed significantly among low, middle, and high ILD-GAPC scores ( P &lt; 0.001 ), unlike ILD-GAP scores ( P = 0.083 ). Conclusions. The ILD-GAPC model could provide more accurate information for predicting prognosis in patients with ILD than the ILD-GAP model.

Abstract

Background

Transcatheter arterial embolization (TAE) has long been used for hemostasis of traumatic or postoperative hemorrhage and embolization of tumors. Previous retrospective studies of TAE for painful bone metastases showed 60%–80% pain reduction with a median time to response of 1–2 days. Compared with radiotherapy and bisphosphonates, time to response appeared earlier than that of radiotherapy or bone-modifying agents. However, few prospective studies have examined TAE for this indication. Here, we describe the protocol for a confirmatory study designed to clarify the efficacy and safety profile of TAE.

Methods

This study will be a multicenter, single-arm confirmatory study (phase 2–3 design). Patients with painful bone metastases from any primary tumor are eligible for enrollment. TAE will be the main intervention. Following puncture of the femoral artery under local anesthesia and insertion of an angiographic sheath, angiography will confirm that the injected region includes tumor vasculature. Catheter position will be adjusted so that the embolization range does not include non-target tissues. Spherical embolic material will then be slowly injected into the artery to embolize it. The primary endpoint (efficacy) is the proportion of subjects with pain relief at 72 h after TAE and the secondary endpoint (safety) is the incidence of all NCI Common Terminology Criteria for Adverse Events version 5.0 Grade 4 adverse events and Grade ≥ 3 necrosis of the central nervous system.

Discussion

If the primary and secondary endpoints are met, TAE can be a treatment choice for painful bone metastases. Trial registry number is UMIN-CTR ID: UMIN000040794.

Trial registration

The study is ongoing, and patients are currently being enrolled. Enrollment started in March 2021. A total of 36 patients have participated as of Aug 2022.

Abstract

Background

In women with inflammatory bowel disease, at least 3 months of preconception corticosteroid-free remission (CFREM) is recommended by experts in current consensus statements. However, data are lacking on the appropriate preconception remission period. We investigated the appropriate preconception CFREM period in women with ulcerative colitis to reduce maternal disease activity and adverse pregnancy outcomes (ie, preterm birth, low birth weight, and small for gestational age).

Methods

We retrospectively examined 141 pregnancies in women with ulcerative colitis at 2 institutions. We categorized the patients into 3 subgroups by their preconception CFREM period (≥3 months, &amp;gt;0 to &amp;lt;3 months, and non-CFREM). We also investigated disease activity during pregnancy and postpartum and adverse pregnancy outcomes in each group.

Results

During pregnancy, the rate of active disease was significantly lower in the ≥3 months and &amp;gt;0 to &amp;lt;3 months CFREM groups compared with that in the non-CFREM group (P &amp;lt; .001 and P = .0257, respectively). Postpartum, the rate of active disease was significantly lower in the ≥3 months CFREM group compared with that in the non-CFREM group (P = .0087). The preconception CFREM period of ≥3 months was an independent inhibitory factor for active disease during pregnancy and postpartum (adjusted odds ratio, 0.15; P = .0035; and adjusted odds ratio, 0.33; P = .027, respectively). Adverse pregnancy outcomes were less common in the &amp;gt;3 months CFREM group compared with those in the other groups, but this difference was not significant.

Conclusions

A preconception CFREM period of more than 3 months may be appropriate for better maternal and adverse pregnancy outcomes, as recommended in consensus statements.

Abstract

Psoriasis is a systemic, chronic, immunologically‐mediated disease affecting approximately 2%–4% of the worldwide population. It is well known that psoriasis is associated with several comorbidities such as metabolic syndrome, cardiovascular disease, and malignancy. Although meta‐analyses and large prospective cohort studies have shown an increased risk of malignancies in patients with psoriasis worldwide, an association between psoriasis and malignancy onset has not yet been established in Japan. We retrospectively analyzed 360 patients with psoriasis at our hospital to evaluate the incidence and types of malignancies in these patients. The incidence rate of malignancy was 14.4% (52/360). Colorectal cancer was the most commonly associated malignancy (20.9%), followed by skin cancer (16.4%), gastric cancer (10.4%), and lung cancer (10.4%). The calculated age‐ and sex‐standardized incidence ratio of malignancies was 1.235 (95% CI 0.952–1.601) which indicated that the malignancy rate was higher in patients with psoriasis than in the general population, although the difference was not statistically significant. Furthermore, the multivariate analysis revealed increased risk of malignancy in males (HR = 3.15; 95% CI 1.381–7.187; p &lt; 0.001), psoriasis onset at older age (HR = 1.08; 95% CI 1.058–1.111; p &lt; 0.01), and psoriatic erythroderma (HR = 4.44; 95% CI 1.354–14.581; p &lt; 0.05). We also observed that treatment with biological agents tends to reduce the risk of developing malignancy; however, no statistical significance was found. These results suggest that periodic screening for malignancy should be recommended in patients with psoriasis having these risk factors and in those with poorly controlled psoriatic inflammation.

Abstract

Aim

The aim of this study was to conduct a 5‐h training programme on anger‐focused emotional management for nurses and verify its effectiveness.

Design

The study used a one‐group pretest–posttest design.

Methods

Participants (N = 283) attended a programme comprising lectures and exercises. The Japanese version of the Buss–Perry Aggression Questionnaire was administered pre‐, post‐ and 3‐month posttraining. Regression analyses were used to assess the effects of the programme by gender.

Results

For the total aggression score, the difference between the pre‐ and posttraining scores was −2.827 points and remained at −1.602 points 3‐month posttraining. Physical aggression scores decreased posttraining, but the scores increased after 3 months. There were statistically significant gender differences in hostility scores; pre‐training scores were slightly higher for men than for women and lower for men after 3 months. Total and physical aggression scores were higher for men than for women. The training programme decreased aggression, and the effect persisted after 3 months.

Abstract

In Japan, comprehensive genomic profiling (CGP) tests for refractory cancer patients have been approved since June 2019, under the requirement that all cases undergoing CGP tests are annotated by the molecular tumor board (MTB) at each government‐designated hospital. To investigate improvement in precision oncology, we evaluated and compared the proportion of cases receiving matched treatments according to CGP results and those recommended to receive genetic counseling at all core hospitals between the first period (11 hospitals, June 2019 to January 2020) and second period (12 hospitals, February 2020 to January 2021). A total of 754 and 2294 cases underwent CGP tests at core hospitals in the first and second periods, respectively; 28 (3.7%) and 176 (7.7%) patients received matched treatments (p &lt; 0.001). Additionally, 25 (3.3%) and 237 (10.3%) cases were recommended to receive genetic counseling in the first and second periods, respectively (p &lt; 0.001). The proportion was associated with the type of CGP test: tumor‐only (N = 2391) vs. tumor‐normal paired (N = 657) analysis (10.0% vs. 3.5%). These results suggest that recommendations regarding available clinical trials in networked MTBs might contribute to increasing the numbers of matched treatments, and that tumor‐normal paired rather than tumor‐only tests can increase the efficiency of patient referrals for genetic counseling.

Background and Purpose: During endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), tract dilation is one of the most important steps, and the placement of conventional metal stents with 8.5 Fr delivery devices is difficult due to the large outer shape of the device. Fine-gauge balloon catheters have become popular because of their stricture penetration ability and ease of dilation. This study aimed to evaluate the utility of fine-gauge balloon catheters. Patients and Methods: This retrospective study involved 38 patients who underwent conventional metal stent placement. The patients were classified into two groups: those who underwent dilation with a fine-gauge balloon catheter before initial metal stenting (balloon dilation group) and those who underwent bougie dilation only (non-balloon dilation group). We evaluated the stenting success rate after initial dilation and adverse events. Results: Seventeen and twenty-one patients were included in the balloon dilation and non-balloon dilation groups, respectively. The stenting success rate after initial dilation was 100% (17/17) in the balloon dilation group and 71.4% (15/21) in the non-balloon dilation group (p = 0.024). As adverse events, peritonitis was observed in one case (4.8%) in the balloon dilation group, and in three cases (14.3%) in the non-balloon dilation group (p = 0.613). Conclusions: Dilation using a fine-gauge balloon catheter before conventional metal stent with 8.5 Fr delivery device placement is considered effective in EUS-HGS.

Objectives

This study was designed to evaluate the effect of rehabilitation in preventing decreased functional status (FS) after community-acquired pneumonia (CAP) in elderly patients.

Design

This was a retrospective observational study.

Setting

Multicentre study was conducted in two medical facilities from January 2016 to December 2018.

Participants

Hospitalised patients with CAP aged over 64 years were enrolled. FS was assessed by the Barthel Index (BI) (range, 0–100, in 5-point increments) at admission and before discharge and graded into three categories: independent, BI 80–100; semidependent, BI 30–75; and dependent, BI 0–25. Multivariable analysis of factors contributing to decreased FS was conducted with two groups: with a decrease of at least one category (decreased group) or without a decrease of category (maintained group).

Primary and secondary outcome measures

The primary outcome was the effect of rehabilitation in preventing decreased FS. The secondary outcomes were factors associated with decreased FS.

Results

The maintained and decreased groups included 400 and 138 patients, respectively. A high frequency of rehabilitation therapy was observed in the decreased group (189 (47.3%) vs 104 (75.4%); p&lt;0.001). Multivariable analysis showed that the factors affecting FS were aspiration pneumonia, Pneumonia Severity Index (PSI) category V, length of stay and age (OR 2.66, 95% CI 1.58 to 4.49; OR 1.92, 95% CI 1.29 to 3.44; OR 1.05, 95% CI 1.04 to 1.07; and OR 1.05, 95% CI 1.02 to 1.09, respectively). After adjusting for factors contributing to decreased FS, rehabilitation showed a limited effect in preventing decreased FS in 166 matched pairs by McNemar’s test (p=0.327).

Conclusions

Aspiration and PSI played important roles in reducing FS. The effect of rehabilitation remains unclear in CAP.

Abstract

Leukotriene receptor antagonists (LTRA) are widely used drugs for treating allergic asthma, and they have recently been suggested to have a suppressive effect on carcinogenesis and cancer cell proliferation. Aberrant crypt foci (ACF) are considered a reliable surrogate biomarker of colorectal cancer. This prospective study explored the chemopreventive effect of an LTRA on colonic ACF formation and the safety of the medicine in patients as a pilot trial leading to a colorectal cancer chemoprevention trial.

This was a nonrandomized, open-label, controlled trial in patients with colorectal ACFs. The participants were allocated to LTRA or observation groups. Patients in the LTRA group received 10 mg of montelukast orally daily for 8 weeks. After the intervention, colonoscopy was performed to evaluate the changes in the number of ACFs.

From November 2017 to March 2020, 40 patients were enrolled. The first 30 were assigned to the LTRA group, and the remaining 10 were assigned to the observation group. In the LTRA group, the mean change in the number of ACFs per patient at 8 weeks from baseline was −2.4 ± 2.2, while the mean change in the observation group was 0.4 ± 2.3 (P = 0.002). There were no severe adverse events.

This is the first study to explore the effect of LTRAs against colorectal ACF formation in humans. LTRAs are potential candidates for chemoprevention in colorectal cancer.

Prevention Relevance:

We conducted the first LTRA chemoprevention trial for human rectal ACFs, which is considered a surrogate marker of colorectal carcinogenesis. 8-week treatment with LTRA suppressed ACF formation and cell proliferation in colonic epithelium. LTRAs are possible candidates for chemoprevention in colorectal cancer.

We aimed to investigate the association between nurses’ electrocardiographic (ECG) monitoring education and their confidence and psychological stress regarding ECG monitoring. In 2019, a web-based cross-sectional study was conducted among Japanese nurses. A multivariable logistic regression analysis was performed to evaluate the effects of education on nurses’ confidence and psychological stress regarding ECG monitoring. In total, 1652 nurses were included in the study. Factors significantly associated with nurses’ confidence were post-graduate education experience (odds ratio [OR], 2.4; 95% confidence interval [CI], 1.6–3.6), ≥11 post-graduate years (OR, 2.2; 95% CI, 1.5–3.1), male gender (OR, 4.4; 95% CI, 2.9–6.6), ≥5 helpful experiences with ECG monitoring (OR, 10.7; 95% CI, 6.0–19.1), work experience in an intensive care unit (OR, 2.3; 95% CI, 1.5–3.7), and work experience in a cardiology department (OR, 1.7; 95% CI, 1.2–2.4). Factors significantly associated with nurses’ psychological stress were male gender (OR, 1.9; 95% CI, 1.2–2.9), ≥5 helpful experiences with ECG monitoring (OR, 1.9; 95% CI, 1.2–2.9), and work experience in an emergency room (OR, 2.4; 95% CI, 1.3–4.8). These results suggest that nurses’ post-graduate ECG monitoring education enhanced their confidence, but did not reduce psychological stress regarding ECG monitoring.

Abstract

Problematic Internet use (PIU) is common and likely to coexist with mental health problems among adolescents with school refusal behavior. To date, no study has revealed to what extent PIU relates to the daily burden compared with other mental health problems. This study has examined the association between daily difficulties and PIU among adolescents with school refusal behaviors.

This cross-sectional study involved all first-visit patients, regardless of diagnosis, aged 10 to 18 years at 2 child/adolescent psychiatric outpatient clinics in Yokohama City, Japan, from April 2016 to March 2018. The Questionnaire-Children with Difficulties (QCD) were obtained from parents. Simultaneously, the severity of PIU was evaluated using the Internet Addiction Test and depressive and anxiety symptoms were evaluated using the Patient Health Questionnaire-9 and General Anxiety Disorder-7 scale in the 2 weeks before the first-visit. From 684 first-visit patients, 227 with school refusal behaviors were enrolled in the study.

PIU was observed in 40% of adolescents with school refusal behaviors. The QCD scores among patients with PIU were significantly lower than those in patients without PIU. Linear regression analysis revealed relationships between PIU and lower QCD scores throughout the day (except at night) and the total score of the day, after controlling for confounders such as depressive and anxiety symptoms.

In conclusion, among adolescents with school refusal behaviors, PIU may affect their parent-assessed daily difficulties particularly experienced throughout the day.

Background

Suicide remains one of the leading causes of death among adolescents. Although recent studies have suggested a strong association between auditory hallucinations and suicidal behaviors, little is known regarding the association between suicidal behaviors and visual hallucinations, which are also common among adolescent psychiatric patients.

Method

A cross‐sectional study of all first‐time patients aged 10–15 years was conducted at three child and adolescent psychiatric outpatient facilities in Kanagawa Prefecture, Japan, from April 2015 to March 2018. Self‐reported questionnaires were administered to evaluate auditory and visual hallucinations, suicide planning, and suicide attempts within the two weeks prior to the first visit. Our logistic regression model included three covariates (sex, age, and presence of major depressive episode) for adjustments. Among the 1285 respondents, 37 who had moderate or severe intellectual disability were excluded, leaving 1248 for analysis.

Results

Among the 1069 patients who completed questionnaire items on hallucinations, 230 (21.5%) experienced auditory or visual hallucinations. After controlling for all confounders, visual hallucinations, but not auditory hallucinations, were significantly associated with increased odds of suicide planning (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.5–4.1). In contrast, auditory hallucinations, but not visual hallucinations, were significantly associated with increased odds of suicide attempts (OR 2.8, 95% CI 1.3–6.1). No interaction effects were observed between suicidal behaviors and auditory or visual hallucinations.

Conclusions

Clinicians should consider the prevalence of both auditory and visual hallucinations among young adolescent patients, with emphasis on auditory hallucinations, given their association with suicide attempts.

AIM: To compare the mid-term oncological results between patients with low rectal cancer who underwent minimally invasive laparoscopic surgery (MILS) and those who underwent open surgery (OS). PATIENTS AND METHODS: Overall, 262 matched patients who underwent primary resection for low rectal cancer between 2000 and 2019 were divided into MILS (n=131; n=107, conventional laparoscopic surgery; n=24, robotic surgery) and OS (n=131) groups. The short- and mid-term outcomes were compared. RESULTS: Similar baseline characteristics were noted. The operative time was longer and blood loss was lesser in the MILS group; the conversion rate was 3.8%. The incidence of postoperative complications was similar. The 2-year cumulative incidence of local recurrence was noted to be much lower in the MILS group (1.9%) than in the OS group (8.4%). MILS had a significantly low hazard ratio (0.208, p=0.036). CONCLUSION: MILS has potential benefits in reducing local recurrence of low rectal cancer.

Background: Community-acquired pneumonia is one of the most common diseases in elderly persons and usually results in a prolonged hospital stay. Discharge planning plays an important role in reducing the length of hospitalization. This study was designed to determine whether early screening for risk factors for delayed discharge could improve the quality of discharge planning. Methods: This retrospective, observational study was conducted in two medical facilities from January 2016 to December 2018. Hospital A used a screening tool on admission (screening group): screening for risk factors for delayed discharge and initiating discharge planning immediately for those for whom it was applicable, and discharge planning in the stable phase for those for whom it was not applicable; and Hospital B initiated discharge planning without screening (usual group). Propensity score-matched pneumonia patients in the two groups were then compared. The primary outcome was length of hospital stay. Results: A total of 648 patients were enrolled in this study. After adjusting for age, sex, aspiration, comorbidity, pneumonia severity index, and key person, 118 pairs underwent analysis. Length of stay was significantly different (20 days vs 13 days, p<0.001) between the groups. There were no differences in duration of antibiotic treatment, in-hospital mortality, and 30-day readmission (9 days vs 9 days, p=0.744; 10 (8.5%) vs 10 (8.5%), p=1.000; 10 (8.5%) vs 9 (7.6%), p=0.811, respectively). Conclusion: Early screening for delayed discharge improved the quality of discharge planning by reducing the length of stay in pneumonia patients.

The aim of the present study was to investigate the psychological effects of the COVID-19 outbreak and associated factors on hospital workers at the beginning of the outbreak with a large disease cluster on the Diamond Princess cruise ship. This cross-sectional, survey-based study collected demographic data, mental health measurements, and stress-related questionnaires from workers in 2 hospitals in Yokohama, Japan, from March 23, 2020, to April 6, 2020. The prevalence rates of general psychological distress and event-related distress were assessed using the 12-item General Health Questionnaire (GHQ-12) and the 22-item Impact of Event Scale-Revised (IES-R), respectively. Exploratory factor analysis was conducted on the 26-item stress-related questionnaires. Multivariable logistic regression analysis was performed to identify factors associated with mental health outcomes for workers both at high- and low-risk for infection of COVID-19. A questionnaire was distributed to 4133 hospital workers, and 2697 (65.3%) valid questionnaires were used for analyses. Overall, 536 (20.0%) were high-risk workers, 944 (35.0%) of all hospital workers showed general distress, and 189 (7.0%) demonstrated event-related distress. Multivariable logistic regression analyses revealed that 'Feeling of being isolated and discriminated' was associated with both the general and event-related distress for both the high- and low-risk workers. In this survey, not only high-risk workers but also low-risk workers in the hospitals admitting COVID-19 patients reported experiencing psychological distress at the beginning of the outbreak.

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) pathogenesis involves abnormal metabolism of cholesterol and hepatic accumulation of toxic free-cholesterol. Elobixibat (EXB) inhibits the ileal bile acid (BA) transporter. EXB and cholestyramine (CTM) facilitate the removal of free cholesterol from the liver by decreasing BA recirculation to the liver, thereby stimulating novel BA synthesis from cholesterol. In this randomised, double-blind, placebo-controlled, parallel-group, phase IIa study, we aim to provide a proof-of-concept assessment by evaluating the efficacy and safety of EXB in combination with CTM in patients with NAFLD. METHODS AND ANALYSIS: A total of 100 adult patients with NAFLD, diagnosed based on low-density lipoprotein cholesterol (LDL-C) level of >120 mg/dL and liver fat content of ≥8% by MRI-based proton density fat fraction (MRI-PDFF), who meet the inclusion/exclusion criteria will be enrolled. The patients will be randomly assigned to receive the combination therapy of 10 mg EXB and 9 g CTM powder (4 g CTM), 10 mg EXB monotherapy, 9 g CTM powder monotherapy or a placebo treatment (n=25 per group). Blood tests and MRIs will be performed 16 weeks following treatment initiation. The primary study endpoint will be the absolute LDL-C level change at week 16 after treatment initiation. The exploratory endpoint will include absolute changes in the liver fat fraction as measured by MRI-PDFF. This proof-of-concept study will determine whether the combination therapy of EXB and CTM is effective and safe for patients with NAFLD. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of Yokohama City University Hospital before participant enrolment. The results of this study will be submitted for publication in international peer-reviewed journals and the key findings will be presented at international scientific conferences. TRIAL REGISTRATION NUMBER: NCT04235205.

Purpose: Among senior community-acquired pneumonia (CAP) survivors, functional status after hospitalization is often decreased. This study investigated the change of functional status affecting delayed discharge. Patients and Methods: This retrospective observational study was conducted in two medical facilities from January 2016 to December 2018. Hospitalized CAP patients >64 years old were divided into two groups: an early group discharged ≤1 week after ending antibiotic treatment and a delayed group discharged >1 week after ending antibiotic treatment. The primary outcome was decline in functional status. Results: The early group comprised 170 patients and the delayed group comprised 155 patients (median age: 78 vs 82 years; p = 0.007). Distribution of the causative microorganisms and initial prescription of antibiotics showed no significant differences in the two groups (p=0.38; p=0.83, respectively) More patients showed decline in functional status in the delayed group than the early group (16 (9.4%) vs 49 (31.6%), p<0.001), even if rehabilitation was more frequently conducted (77 (45.3%) vs 118 (76.1%); p<0.001). Higher medical expenses were observed in the delayed group ($8631 vs $3817, respectively; p<0.001). Multivariable regression analysis of factors contributing delayed discharge revealed that decreased functional status, pneumonia severity index (PSI) categories, rehabilitation enrolled, aspiration and age were independently associated with delayed discharge (odds ratio 4.31, 95% confidence interval (CI) 2.32-7.98; 2.34, 95% CI 1.43-3.82; 15.96, 95% CI 4.56-55.82 (PSI V vs II); 2.48, 95% CI 1.11-5.98; and 1.03, 95% CI 1.01-1.06; respectively). Conclusion: Functional status decline was independently associated with extended hospitalization.

BACKGROUND: Low population density may be associated with high mortality in acute myocardial infarction (AMI) patients. The purpose of this study was to investigate the effect of population density and hospital primary percutaneous coronary intervention (PCI) volume on AMI in-hospital mortality in Japan.Methods and Results:This is a retrospective study of 64,414 AMI patients transported to hospital by ambulances. The main outcome measure was in-hospital mortality. The median population density was 1,147 (interquartile range, 342-5,210) persons/km2. There was a significant negative relationship between population density and in-hospital mortality (OR for a quartile down in population density 1.086, 95% CI 1.042-1.132, P<0.001). Patients in less densely populated areas were more often transported to hospitals with a lower primary PCI volume, and they had a longer distance to travel. By using multivariable analysis, primary PCI volume was found to be significantly associated with in-hospital mortality, but distance to hospital was not. When divided into the low- and high-volume hospitals, using the cut-off value of 115 annual primary PCI procedures, the increase in in-hospital mortality associated with low population density was observed only in patients hospitalized in the low-volume hospitals. CONCLUSIONS: Increased in-hospital mortality related to low population density was observed only in AMI patients who were transported to the low primary PCI volume hospitals, but not in those who were transported to high-volume hospitals.

BACKGROUND: Use of the antipsychotic drug olanzapine by patients with schizophrenia is associated with autonomic nervous system (ANS) dysfunction. It is presumed that there are interindividual differences in ANS dysfunction that correspond to pharmacogenetics. In this study, we investigated whether genetic polymorphisms in ABCB1, CYP1A2, and UGT1A4 are associated with this observed ANS dysfunction. METHODS: A total of 91 schizophrenia patients treated with olanzapine monotherapy participated in this study. A power spectral analysis of heart rate variability was used to assess ANS activity. The TaqMan system was used to genotype seven single nucleotide polymorphisms (SNPs) in CYP1A2 (rs2069514 and rs762551), UGT1A4 (rs2011425), and ABCB1 (rs1045642, rs1128503, rs2032582, rs2235048). RESULTS: Sympathetic nervous activity was significantly higher in individuals with the UGT1A4 rs2011425 G allele than in those with the UGT1A4 rs2011425 non-G allele (sympathetic activity, p = .001). Furthermore, sympathetic nervous activity was also significantly associated with UGT1A4 rs2011425 genotype as revealed by multiple regression analysis (sympathetic activity, p = .008). CONCLUSIONS: We suggest that the UGT1A4 rs2011425 polymorphism affects olanzapine tolerability because it is associated with the observed side effects of olanzapine in schizophrenia patients, namely sympathetic dysfunction.

To estimate pregnancy complications in women newly diagnosed with gestational diabetes mellitus (GDM) according to the new International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria and verify the validity of introducing the IADPSG criteria in Japan. This retrospective study included data from women with singleton delivery at 22 weeks or later at a tertiary hospital during 2000-2009. We compared pregnancy outcomes between women who would now be diagnosed with GDM according to the IADPSG criteria but not by the old JSOG criteria (IGT group, n = 503) and women with normal glucose tolerance according to both the criteria (NGT group, n = 2,789). Multivariate analysis was performed and adjusted for background factors. Maternal age at delivery and pre-pregnancy BMI were significantly higher in the IGT group than in the NGT group, while gestational weeks at delivery did not differ between the groups. No difference was observed in the rates of GDM-related composite complications (defined as cases with at least one of the following: macrosomia, shoulder dystocia, neonatal hypoglycemia, neonatal hyperbilirubinemia, or neonatal respiratory distress syndrome) at 11.9% and 8.8% (adjusted odds ratio (OR) 1.30, 95% confidence interval (CI) 0.90-1.87, p = 0.16). Pregnancy outcomes did not differ significantly between the IGT and NGT groups, except for frequencies of total neonatal admissions at 10.5% and 7.1%, respectively (adjusted OR 1.55, 95% CI 1.12-2.13, p < 0.01).

Background/Aims: Strategies for an effective intervention after chronic kidney disease (CKD) screening have not been well examined. We describe the rationale and design of a protocol of a pragmatic randomized controlled trial (RCT) to test the effect of a behavioral intervention using the nudge approach in behavioral economics on CKD patients' visiting behaviors to physicians and change in their kidney function after CKD screening. Methods: The RCT will include CKD patients (N = 4500) detected at screening (estimated glomerular filtration rate [eGFR] <60 mL/min/1.74 m2 or urine protein ≥1+), aged 40-63 years. The two intervention groups will receive a "usual letter" and "nudge-based letter," while the control group will only receive a conventional follow-up. Our primary outcome is proportion of patients' visiting physicians for 6 months after the intervention; the secondary outcome is change in the eGFR at 2 years after the intervention. Results: We developed an efficient intervention program after CKD screening and designed the pragmatic RCT to assess its effectiveness in the real world. Our trial is unique in that it investigates the effect of the nudge approach in behavioral economics. By the end of 2018, we have enrolled 1,692 participants, and randomized 677 participants into the usual letter group, 677 participants into the nudge-based letter group, and 338 participants into the control group. We have confirmed that health checkup data could identify a large number of eligible participants. Conclusion: The trial's results will contribute to filling in the gap between screening and subsequent medical interventions for preventing CKD progression.

Abstract

Background and Aim

Oral 5‐aminosalicylic acid (5‐ASA) is recommended for the therapy of mild to moderate intestinal Behçet's disease (BD). However, the induction remission efficacy and endoscopic outcomes of 5‐ASA are unknown. We investigated remission induction at 8 weeks, endoscopic outcomes until 52 weeks, and event‐free survival at 52 weeks in patients with intestinal BD treated with 5‐ASA.

Methods

Forty‐one patients with intestinal BD were treated with oral 5‐ASA. Clinical remission was evaluated with the Crohn's disease activity index (CDAI). The endoscopic response was evaluated using the modified global gastrointestinal endoscopic assessment scores. Rescue therapy‐free survival and surgery‐free survival at 52 weeks were estimated, and predictive factors for a clinical response at weeks 8 and 52 were identified.

Results

Seven patients (17%) withdrew 5‐ASA early (≤ 8 weeks) because of adverse events. At week 8, clinical efficacy could be accurately evaluated in 28 patients, and the response and remission rates were 61% and 57%, respectively, using the CDAI. Endoscopic evaluation was achieved in 17 patients up to 52 weeks, and the endoscopic response and remission rates were 71% and 35%, respectively. The probabilities of rescue therapy‐free survival and surgery‐free survival were 73% and 100%, respectively, at 52 weeks in all 41 patients. The predictive factors for therapeutic effectiveness at week 8 were a higher baseline C‐reactive protein level and CDAI, but they were negative predictive factors for a 52‐week response.

Conclusions

5‐ASA is effective for clinical and endoscopic induction and maintaining a response in patients with mild to moderate intestinal BD.

BACKGROUND: The tumor, node, metastasis classification system for staging esophageal cancer does not include tumor volume although it may be an important prognostic factor. We evaluated the prognostic value of tumor volume in esophageal cancer. METHODS: We performed a retrospective study in patients with histologically confirmed primary esophageal cancer who underwent curative esophagectomy at our facility between April 1992 and December 2013. The Tumor Depth Parameter (TDP) was defined as mucosa = 1, submucosa = 2, muscularis propria = 3, adventitia = 4, and invasion into adjacent organs = 5. The pathological Tumor Volume Index (TVI) was defined as the major axis × the minor axis × TDP. The appropriate tumor diameter and TVI cutoff values were determined by the Youden index obtained from the receiver operating characteristic curve. Prognostic factors for overall survival were evaluated by univariate analysis and Cox proportional hazards regression models. RESULTS: We enrolled 302 patients. In the univariate analysis, patient age and sex, thoracoscopic surgery, tumor depth of invasion and diameter, lymph node metastasis, and the TVI were significantly associated with overall survival. In our multivariate analysis, patient age and sex, thoracoscopic surgery, lymph node metastasis, and the TVI were independently associated with overall survival. CONCLUSIONS: The pathological TVI was an independent prognostic factor in patients with esophageal carcinoma and could be included in the staging system of esophageal cancer.

OBJECTIVE: Cesarean delivery at a preterm gestational age has been related to maternal complications such as bleeding and infection. However, previous reports are conflicting, and there is no consensus on the matter. We aimed to clarify the adverse effect of preterm cesarean delivery with an emphasis on maternal bleeding. STUDY DESIGN: We conducted a retrospective study comparing the frequency of maternal adverse outcome between preterm emergency cesarean delivery and term emergency cesarean delivery. Nine hundred and forty seven preterm cases and 1056 full-term cases were included in the study. We analyzed the frequency of abnormal bleeding defined as 1500 mL or more as primary outcome, blood transfusion rate, and rate of postoperative administration of antibiotics as secondary outcome. Logistic regression analysis was performed for confounding variables; age at delivery, primiparity, obesity, prior history of uterine surgery, abnormal placental position, abnormal glucose tolerance, hypertension during pregnancy, early rupture of membranes, and general anesthesia use during operation. As secondary analysis, to study the effects of method of incision, we compared adverse outcomes among classical cesarean delivery, inverted T incision, and upper segment incision within preterm emergency cesarean delivery. RESULTS: Preterm cesarean delivery had significantly higher rates of abnormal bleeding, transfusion and use of antibiotics than term cesarean delivery. Among the preterm delivery, classical incision was related to increased rate of blood transfusion and need for antibiotic treatment. CONCLUSION: Preterm cesarean delivery increases the risk of maternal bleeding. This should be considered especially in the setting of early preterm birth.

PURPOSE: Capeox is widely used as an adjuvant chemotherapy regimen of colorectal cancer that does not require central vein catheter insertion. However, oxaliplatin-related vascular pain with peripheral administration is a major adverse event. We assessed the preventive effect of Celecoxib on oxaliplatin-related vascular pain. METHODS: A multicenter study of the Yokohama Clinical Oncology Group (YCOG) in Japan. This study was an open label, randomized non-comparative phase II study between Capeox without Celecoxib (C+ Group) and with it (C- group). The primary endpoint was the appearance frequency of grade ≥ 2 vascular pain according to the Verbal Rating Scale (VRS). RESULTS: Between October 2012 and February 2014, 81 patients were recruited to this study and randomly divided into 2 groups: 38 patients in the C- group and 39 patients in the C+ group. Four cases were excluded at the analysis stage because they had not received the allocated intervention. The rate of grade ≥ 2 vascular pain was 55.3% in the C- group and 53.8% in the C+ group (p = 1.000). CONCLUSIONS: Celecoxib was unable to prevent oxaliplatin-related vascular pain in this study. However, it may be able to decrease the vascular pain that patients already have.

BACKGROUND/AIM: Nanoparticle albumin-bound (nab)-paclitaxel has demonstrated antitumor activity against advanced gastric cancer. However, gastric cancer patients can be difficult to treat with the recommended dose because of the high incidence of adverse toxicities. The aim of this study was to evaluate the safety and effectiveness of low-dose nab-paclitaxel in a multicenter, single-arm, phase II study. PATIENTS AND METHODS: Treatment included low doses of 180 mg/m2 nab-paclitaxel administered on day 1 of each 21-day cycle. The primary endpoint was defined as the overall response rate (ORR). The secondary endpoints included progression-free survival (PFS), safety, and overall survival (OS). A total of 34 patients were enrolled in the full-analysis set. RESULTS: The ORR was 5.9%. The median PFS and OS were 2.4 months and 9.2 months, respectively. The most common grade 3/4 toxicities were anemia (8.8%), neutropenia (5.9%), appetite loss (5.9%) and peripheral sensory neuropathy (5.9%). No treatment-related deaths occurred. CONCLUSION: The tri-weekly low dose of nab-paclitaxel therapy is effective towards advanced gastric cancer patients with good tolerability and an acceptable margin of safety.

BACKGROUND: Patients with schizophrenia have a higher mortality risk than the general population. Additionally, the autonomic nervous system (ANS) activity of patients with schizophrenia is lower and more dysfunctional than that of the general population. Nonetheless, the association between ANS dysfunction and mortality in schizophrenia is unclear. The aim of this study was to investigate the association between ANS activity and mortality in schizophrenia and to evaluate the predictive values of heart rate variability for long-term survival. METHODS: This study involves the 10-year follow-up of a sample population consisting of 59 Japanese inpatients with schizophrenia between 60 and 70 years of age from 2007 to 2016. The ANS activity of all patients was evaluated using heart rate variability in 2007. RESULTS: Fifty-three participants could be followed up because they stayed in the hospital during the follow-up period. Of these patients, 11 died during follow-up. Their mean age at death was 70.55 ± 3.45 years. The parasympathetic activity of nonsurvivors was significantly lower than that of survivors, and multiple logistic regression analysis showed a significant association between death and parasympathetic activity. CONCLUSION: We suggest that decreased parasympathetic activity could be associated with 10-year all-cause mortality in older schizophrenic patients.
