Abstract
AIM Although the Fontan procedure has improved the survival of patients with single-ventricle heart disease, the long-term consequences of the procedure have been a concern. This study aimed to explore the patients' postoperative clinical characteristics, including a diagnosis of Fontan-associated liver disease (FALD). METHODS A nationwide Japanese epidemiological survey of post-Fontan patients was undertaken in 2021. The survey targets were selected from all departments of pediatrics, pediatric surgery, cardiology, cardiovascular surgery, and gastroenterology using stratified random sampling by the number of beds. Each department was asked to complete a mail-back questionnaire on the numbers of patients and their clinical characteristics. The diagnosis of FALD was made by each attending physician. RESULTS The estimated number of post-Fontan patients was 7810 (95% confidence interval, 5430-10 200) in 2020, with a period prevalence of 61.9 per million. During the follow-up of 13.8 years after the Fontan procedure, 40% of patients were diagnosed with FALD. An elevated γ-glutamyl transpeptidase level was the most common finding leading to the FALD diagnosis (41%), and 45% of the patients also showed liver fibrosis. Compared with non-FALD patients, FALD patients were older, had longer duration since the Fontan procedure, and had more severe cardiac or liver conditions. However, more than half of the non-FALD patients had elevated liver enzyme levels, suggesting underestimation of the number of FALD patients. CONCLUSIONS In 2020, approximately 40% of post-Fontan patients underwent follow-up with a diagnosis of FALD, although the lack of established diagnostic criteria for FALD could affect the reported prevalence of FALD.

Abstract
The excess mortality of COVID-19 solid organ transplant recipients (SOTRs) throughout the pandemic remains unclear. This prospective cohort study based on the Japanese nationwide registry included 1,632 SOTRs diagnosed with COVID-19 between February 1, 2020, and July 31, 2022, categorized based on dominant phases of variants of concern (VOC): Waves 1-3 (Beta), 4 (Alpha), 5 (Delta), 6 (Omicron BA.1/BA.2), and 7 (Omicron BA.5). Excess mortality of COVID-19-affected SOTRs was analyzed by calculating standardized mortality ratios (SMRs). Overall, 1,632 COVID-19-confirmed SOTRs included 1,170 kidney, 408 liver, 25 lung, 20 heart, 1 small-intestine, and 8 multiorgan recipients. Although disease severity and all-cause mortality decreased as VOC transitioned, SMRs of SOTRs were consistently higher than those of the general population throughout the pandemic, showing a U-shaped gap that peaked toward the Omicron BA.5 phase; SMR (95% CI): 6.2 (3.1-12.5), 4.0 (1.5-10.6), 3.0 (1.3-6.7), 8.8 (5.3-14.5), and 21.9 (5.5-87.6) for Waves 1-3 (Beta), Wave 4 (Alpha), Wave 5 (Delta), Wave 6 (Omicron BA.1/2), and Wave 7 (Omicron BA.5), respectively. In conclusion, COVID-19 SOTRs had greater SMRs than the general population across the pandemic. Vaccine boosters, immunosuppression optimization, and other protective measures, particularly for older SOTRs, are paramount.

Abstract
AIM There are few data regarding the safety and effectiveness of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in patients with intractable hepatobiliary diseases. We conducted a multicenter, questionnaire-based, cross-sectional study to determine the safety and effectiveness of the SARS-CoV-2 vaccines in Japanese patients with intractable hepatobiliary disease. METHODS Patients aged ≥18 years with autoimmune hepatitis (AIH), primary biliary cholangitis, primary sclerosing cholangitis, Budd-Chiari syndrome, idiopathic portal hypertension, and extrahepatic portal vein obstruction at each center were consecutively invited to join the study. Participants were asked to complete a questionnaire regarding their characteristics, vaccination status, post-vaccination adverse effects, and SARS-CoV-2 infection. Additionally, liver disease status, treatment regimens, and liver function test values pre- and post-vaccination were collected. RESULTS The survey was conducted from September 2021 to May 2022, and 528 patients (220 AIH, 251 primary biliary cholangitis, 6 AIH- primary biliary cholangitis/primary sclerosing cholangitis overlap, 39 primary sclerosing cholangitis, 4 Budd-Chiari syndrome, 5 idiopathic portal hypertension, and 3 extrahepatic portal vein obstruction) participated in the study. Post-vaccination adverse effects were comparable to those observed in the general population. Post-vaccination liver injuries classified as grade 1 or higher were observed in 83 cases (16%), whereas grades 2 and 3 were observed in only six cases (1.1%); AIH-like liver injury requiring treatment was not observed. Overall, 12 patients (2.3%) were infected with SARS-CoV-2, and only one patient was infected 6 months after the second vaccination. CONCLUSION SARS-CoV-2 vaccines demonstrated satisfactory safety and effectiveness in Japanese patients with intractable hepatobiliary diseases.

Abstract
Background To evaluate antibody responses against the primary series of vaccination of severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2] vaccines in the staff and residents of Japanese geriatric intermediate care facilities. Methods All subjects (159 staff and 96 residents) received two doses of the BNT162b2 mRNA vaccine 3 weeks apart. Baseline data of subject were collected using a structured form. Serum samples were collected three times: before vaccination, 3 weeks after the first dose, and 4 weeks after the second dose, and anti-receptor binding domain of the spike protein of SARS-CoV-2 [anti-RBD] IgG was measured using two immunoassays. Results After the second dose, geometric mean titers [GMT] of anti-RBD with both the Abbott and Roche assay were significantly lower in residents than staff (2282 AU/mL vs. 8505 AU/mL, and 258 U/mL vs. 948 U/mL, respectively). Multivariate analysis of characteristics affecting antibody responses (≥1280 AU/mL for Abbott and > 210 U/mL for Roche) showed lower odds ratios [ORs] for older age (adjusted OR per 10 year increase [aOR] = 0.62, 95 % confidence interval [95 %CI]; 0.38-1.02), steroid usage (aOR = 0.09, 95 %CI; 0.01-0.60) and regular nonsteroidal anti-inflammatory drugs [NSAIDs] usage (aOR = 0.16, 95 %CI; 0.03-0.88). Conclusions Elderly people and steroid and NSAID users had lower antibody responses following the second vaccine dose.

Abstract
INTRODUCTION Patients with lung cancer have a high risk of influenza complications. International guidelines recommend annual influenza vaccination for patients with cancer. Immune checkpoint inhibitors (ICIs) are progressively used to treat lung cancer. Data regarding immunogenicity and safety of influenza vaccine are limited in patients with lung cancer receiving ICIs; therefore, we conducted this single-center, prospective observational study in the Japanese population. METHODS Patients with lung cancer receiving ICIs and influenza immunization were enrolled. Blood samples were collected from patients for serum antibody titer measurement pre- and 4 ± 1 weeks post-vaccination. The primary endpoint was seroprotection rate (sP) at 4 ± 1 weeks post-vaccination. The secondary endpoints were geometric mean titer (GMT), mean fold rise, seroresponse rate (sR), seroconversion rate (sC), and immune-related adverse events (irAEs), defined as adverse effects caused by ICI administration, 6 months post-vaccination. RESULTS Influenza vaccination in the 23 patients included in the immunogenicity analyses significantly increased GMT for all strains, and sP, sR, and sC were 52%-91%, 26%-39%, and 26%-35%, respectively. In the 24 patients included in the safety analyses, 7 (29%) and 5 (21%) patients exhibited systemic and local reactions, respectively. Only one patient (4%) (hypothyroidism, grade 2) showed post-vaccination irAEs. CONCLUSIONS Overall, influenza vaccination in patients with lung cancer receiving ICIs showed acceptable immunogenicity and safety, thus supporting annual influenza vaccination in this population.

Abstract
BACKGROUND The association between inactivated influenza vaccination and viral load in young children remains unclear. METHODS During the 2013/2014 to 2017/2018 influenza seasons in Japan, children under 6 years of age with pre-defined influenza-like illness and influenza-positive status by real-time RT-PCR were recruited at pediatric clinics for this observational study. Influenza viral load was measured for the most predominant subtype/lineage in each season. Using median dichotomized viral load as an outcome, a multilevel logistic regression model was applied to estimate the multivariable adjusted odds ratio (MOR) and 95% confidence interval (CI) for higher viral load. RESULTS A total of 1,185 influenza-positive children were analyzed. The median log10 viral load copy number (copies per milliliter) was 5.5 (interquartile range, 4.6 to 6.1) and did not differ by vaccination status: 5.5 for unvaccinated, 5.7 for one dose, and 5.5 for two doses (p = 0.67). The MOR of vaccinated (one or two doses) versus unvaccinated children was 1.19 (95% CI: 0.86-1.64). Other factors showing significant associations with higher viral load were positive results for A(H1N1)pdm09 and A(H3N2) in comparison with B/Yamagata. The respective MORs were 3.25 (95% CI: 2.28-4.64) and 1.81 (95% CI: 1.32-2.49). Significantly elevated MORs against higher viral load were also observed for higher body temperature at influenza diagnosis and shorter duration from fever onset to specimen collection. CONCLUSION No association was observed between inactivated-influenza vaccination and viral load at influenza-positive diagnosis. Influenza subtype/lineage, body temperature, and time elapsed since fever onset were significantly associated with viral load.

Abstract
The coronavirus disease-19 (COVID-19) vaccine efficacy and immunogenicity in the immunocompetent population are well established. However, in solid organ transplant (SOT) recipients, because of their use of immunosuppressive medication, the immunogenicity of these severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines remains suboptimal. Both BNT162b2 and mRNA1273 have been used for some time, but their immunogenicity has not been directly compared in this immunocompromised patient group. We performed a post-hoc analysis of a previous prospective cohort study. The inclusion criteria were adult SOT recipients with active grafts at least 1 month after SOT. After giving consent, participants chose to receive either BNT162b2 or mRNA1273 vaccine. Anti-spike-protein-S antibody against SARS-CoV-2 was measured. Propensity scores were calculated via logistic regression to transform the probability of having received either BNT162b2 or mRNA1273 vaccine, and a model was developed. We enrolled 623 SOT recipients. In the propensity score-matched analysis, 100 recipients were selected for BNT162b2 and 100 for mRNA1273. SARS-CoV-2 anti-spike protein antibody positivity with BNT162b2 versus mRNA1273 at 3 weeks after the first dose, 1 month after the second dose, 3 months after the second dose, and 6 months after the second dose were 10% versus 19% (P = .07), 51% versus 58% (P = .30), 74% versus 88% (P = .01), and 78% versus 87% (P = .13), respectively. We conducted a propensity score-matched comparison of BNT162b2 and mRNA1273 vaccines as the primary series of COVID-19 vaccines in SOT recipients. We found significantly better immunogenicity with the mRNA1273 vaccine than with BNT162b2.

Abstract
Congenital diaphragmatic hernia (CDH) is a life-threatening condition characterized by the herniation of abdominal organs into the thorax, resulting in hypoplastic lungs and pulmonary hypertension. The impact of the first cry, a crucial event for lung transition during birth, on CDH patients remains unclear. This study investigated the impact of the first cry during birth on CDH patient survival, along with other prognosis factors. A multi-institutional retrospective study assessed CDH patient characteristics and survival rates by analyzing factors including the first cry, disease severity, birth weight, Apgar scores, oxygenation index (OI) and surgical closure. Among the CDH patients in the study, a positive first cry was linked to 100% survival, regardless of disease severity (p < 0.001). Notably, the presence of a positive first cry did not significantly affect survival rates in patients with worse prognostic factors, such as low birth weight (<2500 g), high CDH severity, low Apgar scores (1 min ≤ 4), high best OI within 24 h after birth (≥8), or those who underwent patch closure. Furthermore, no significant association was found between the first cry and the use of inhaled nitric oxide (iNO) or extracorporeal membrane oxygenation (ECMO). In conclusion, this study suggests that the first cry may not have a negative impact on the prognosis of CDH patients and could potentially have a positive effect.

Abstract
AIM The risk of developing infectious diarrhea among elderly residents at Japanese geriatric intermediate care facilities is unclear. We investigated the incidence rate and risk factors of norovirus-related diarrhea at such facilities. METHODS This prospective cohort study followed 1727 residents from November 2018 to April 2020 at 10 geriatric intermediate care facilities in Osaka, Japan regarding the occurrence of diarrhea. Resident data were collected from their medical records using structured forms at two to three of the following three time points: at recruitment, if they developed diarrhea, and when they left the facility. Residents who developed diarrhea were tested using rapid diagnostic tests for norovirus. Cox proportional hazard model was employed to hazard ratios (HRs) with 95% confidence intervals (CIs) to estimate the risk factors for norovirus-related diarrhea. RESULTS During the study period, 74 residents developed diarrhea, 13 of whom were norovirus positive. The incidence rate of norovirus-related diarrhea was 10.11 per 1000 person-years (95% CI: 4.61-15.61). In terms of risk factors, people with care-needs level 3 were at a higher risk for developing norovirus-related diarrhea (adjusted HR [aHR] = 7.35, 95% CI: 1.45-37.30). Residents with hypertension (aHR = 3.41, 95% CI: 1.05-11.04) or stroke (aHR = 8.84, 95% CI: 2.46-31.83), and those who walked with canes (aHR = 16.68, 95% CI: 1.35-206.52) also had a significantly higher risk for norovirus-related diarrhea. CONCLUSIONS Throughout the study period, the incidence of development of diarrhea was low. Care-needs level 3, stroke, hypertension and use of a cane were identified as risk factors for norovirus-related diarrhea in Japanese geriatric intermediate care facilities. Geriatr Gerontol Int 2023; 23: 179-187.

Abstract
BACKGROUND AND AIMS Ustekinumab has been proven to be effective for treatment of patients with Crohn's disease; however, 30-40% of patients have been reported to lose clinical response within 2 years. We aimed to evaluate the efficacy of ustekinumab and identify predictors of short-term and long-term efficacy in Crohn's disease. METHODS Patients with Crohn's disease receiving their first ustekinumab infusion in our hospital between June 2017 and September 2020 were prospectively enrolled. Concentrations of serum cytokines and chemokines were measured using a multiplex bead array assay. RESULTS Fifty-nine Crohn's disease patients were enrolled in this study. Among 34 clinically active patients, 38.2% achieved a clinical response at week 8. None of the assayed factors were associated with short-term clinical response. Cumulative persistence rates of ustekinumab were 77.6% at 1 year and 58.9% at 2 years. Univariate Cox regression analysis revealed that Harvey-Bradshaw Index scores at baseline, concomitant immunomodulator treatment, and concentrations of interferon gamma-induced protein-10, monocyte chemoattractant protein-1 (MCP-1), and interleukin (IL)-1RA, IL-4, IL-6, and IL-8 were significantly associated with loss of efficacy. Multivariate Cox regression analysis found that biologic naïve status (hazard ratio [HR]: 0.1191, 95% confidence interval [CI]: 0.02458-0.5774) and MCP-1 concentrations (HR: 1.038, 95% CI: 1.015-1.062) were significantly and associated with loss of sustained efficacy for ustekinumab treatment. CONCLUSIONS Our findings suggest that pretreatment serum MCP-1 analysis, combined with a history of biologic use, could be a novel biomarker for predicting the long-term efficacy of ustekinumab in patients with Crohn's disease.

Abstract
Background: In Japan, freeze-dried live attenuated varicella-zoster vaccine BIKEN is available for adults aged ≥50 years to prevent herpes zoster (HZ). A prospective cohort study of 1200 healthy adults and 300 patients with underlying illness confirmed vaccine safety between 2016 and 2017. However, evidence of vaccine effectiveness (VE) is limited. Methods: VE against HZ and postherpetic neuralgia (PHN) was evaluated in the vaccinated cohort of the previous safety study in a follow-up study between 2021 and 2022 and compared with unvaccinated family members. Self-administered questionnaires determined retrospective experiences of HZ and PHN diagnosis. Logistic regression estimated the VE by calculating the outcome odds ratio (OR) in vaccinated vs. unvaccinated groups: VE = (1 - OR) × 100(%). Results: Overall, 1098 vaccinated and 518 unvaccinated subjects were analysed. Between 2016 and 2022, 26 vaccinated (2.4%) and 22 unvaccinated (4.2%) subjects reported HZ diagnosis, and 3 vaccinated (0.3%) and 2 unvaccinated (0.4%) subjects reported PHN. Adjusted VE against a clinical diagnosis was 41% for HZ [-6% to 67%], with marginal significance, and 16% [-408% to 86%] for PHN. Stratification by age, sex, or comorbidities had an adjusted VE against HZ of ~40%, which was similar between strata. Conclusion: Freeze-dried live attenuated varicella-zoster vaccine reduces the risk of HZ regardless of age, sex, or comorbidities.

Abstract
Although nationwide immunization with SARS-CoV-2 mRNA vaccines began in February 2021, the evaluation of vaccine effectiveness (VE) using a test-negative design has not been conducted adequately in Japan. To evaluate the effectiveness of the SARS-CoV-2 mRNA vaccines, we conducted a test-negative case-control study during the periods dominated by the Delta and Omicron variants. In total, 518 and 358 adult participants with COVID-19-like symptoms were tested for the virus from August to October 2021 (Delta variant predominance) and in February 2022 (Omicron variant surge), at the Kawasaki Saiwai Clinic. During Delta variant predominance, the effectiveness of full vaccination was 90.4% (95% confidence interval [CI]: 82.1-94.8) and 97.3% (95% CI: 71.7-99.7) against all COVID-19 and moderate-to-severe disease, respectively. However, partial vaccination failed to show effectiveness against moderate-to-severe COVID-19. The effectiveness of the mRNA vaccines against all COVID-19 infection declined to 16.1% (95% CI: -81.0 to 61.1) in February 2022. Our results indicated that, although mRNA vaccines showed significant preventive effects against all COVID-19 during Delta variant predominance, these preventive effects waned during Omicron variant surge. To the best of our knowledge, this is the first study that evaluated VE in the Japanese population during both periods.

Abstract
Background and Aim The number of patients with ulcerative colitis (UC) has been increasing in Japan. To elucidate the risk factors for developing UC in Japan, a hospital-based case-control study was conducted. This study examined the association between smoking/drinking habits and UC onset in detail. Methods Cases comprised 132 Japanese patients who had been newly diagnosed with UC between 2008 and 2014 at 38 collaborating hospitals in Japan, and controls comprised 167 patients without UC. Detailed data on smoking and drinking habits were collected using a self-administered questionnaire. Results Ex-smokers showed an increasing odds ratio (OR) for UC development compared with never smokers (OR 2.42, 95% confidence interval 1.24-4.72). The ORs of ex-smokers were particularly high among subjects aged less than 40 years, subjects who had smoked more than 10 pack-years, and subjects who were within 13 years of quitting smoking. Regarding drinking habits, ex-drinkers also showed a more than twofold higher OR for UC compared to never drinkers. Ex-drinkers 40 years or older, ex-drinkers who had consumed more than 364 drink-years, and subjects who were less than 6 years after quitting drinking showed increased ORs for UC. Conclusion These findings suggest the need for careful attention for UC onset among heavy smokers who quit smoking before 40 years of age and heavy drinkers who quit drinking at ≥40 years of age.

Abstract
Endoscopic biliary drainage is the recommended 1st-line treatment for malignant biliary obstruction. Although a high incidence of febrile neutropenia has been reported in patients treated with FOLFIRINOX and a biliary stent, it remains unknown whether the biliary stent contributes to patient survival. Thus, we aimed to elucidate the effects of biliary stents on the survival of patients with advanced pancreatic cancer treated with modified FOLFIRINOX (mFFX). We retrospectively reviewed medical charts of patients with advanced pancreatic cancer treated with mFFX between January 2014 and April 2020. We compared the overall survival (OS) of patients with and without biliary stent during mFFX treatment and examined the independent effect on mortality using propensity score matching. Overall, we included 89 patients (stent group, n = 24; non-stent group, n = 65). The proportion of patients with pancreatic head cancer was significantly higher in the stent group than in the non-stent group (P < .01). Stratification analysis in patients with pancreatic head cancer revealed that OS was significantly shorter in the stent group than in the non-stent group (P = .03). After propensity score matching, 19 pairs of patients in each group were analyzed. The stent group revealed a significantly shorter survival than the non-stent group (median OS, 10.3 vs 24.9 months; P < .01). The incidences of febrile neutropenia (P = .01) and biliary tract-related events that required biliary stenting or stent replacement (P < .01) were significantly higher in the stent group than in the non-stent group. Stent insertion was an independent risk factor for overall mortality. Biliary stents may reduce survival in patients with advanced pancreatic cancer. The rate of febrile neutropenia was higher in the stent group than in the non-stent group. There is a need to assess the patient's condition with discretion and develop a treatment strategy with short prognosis in mind after stent insertion.

Abstract
BACKGROUND In the era of childhood pneumococcal conjugate vaccine (PCV) immunization, especially 13-valent pneumococcal conjugate vaccine (PCV13) immunization, serotype replacement of Streptococcus pneumoniae and herd immunity in adults have been reported worldwide. Therefore, continuous evaluation of the effectiveness of the pneumococcal vaccine in adults is crucial because vaccine effectiveness may change owing to these factors. The purpose of this study was to evaluate the effectiveness of the 23-valent pneumococcal polysaccharide vaccine (PPSV23) against all-cause pneumonia and pneumococcal pneumonia in older individuals with community-acquired pneumonia (CAP) after the introduction of childhood PCV13 in Japan, a topic that has remained largely unexplored. METHODS We evaluated pneumococcal vaccine effectiveness in this multicenter, matched case-control study conducted in hospitals and clinics. Cases included patients (aged ≥ 65 years) newly diagnosed with CAP between October 2016 and September 2019. A maximum of five non-pneumonia control patients matched for sex, school grade, date of outpatient visit, and medical institution were selected for each case. Conditional logistic regression models were used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) of pneumococcal vaccines for the occurrence of all-cause CAP and pneumococcal CAP. RESULTS The analysis included 740 individuals (142 patients and 598 controls). The median age of participants was 75 years (men: 54%). The adjusted OR for pneumococcal vaccination against all-cause CAP was 1.31 (95% CI: 0.84-2.06), while that for PPSV23 vaccination in the previous 5 years was 1.33 (95% CI: 0.85-2.09). The adjusted OR for PPSV23 vaccination in the previous 5 years against pneumococcal CAP was 0.93 (95% CI: 0.35-2.50). CONCLUSIONS This study was unable to demonstrate the effectiveness of PPSV23 against all-cause and pneumococcal pneumonia after the introduction of childhood PCV13 in Japan. Nonetheless, additional studies are needed to validate these results.

Abstract
Background Although several assays are used to measure anti-receptor-binding domain (RBD) antibodies induced after severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccination, the assays are not fully comparable in practice. This study evaluated the immunogenicity of the BNT162b2 mRNA vaccine in healthy adults using two immunoassays. Methods This prospective cohort study included SARS-CoV-2-naïve adults, predominantly healthcare workers, aged 20–64 years, who received two BNT162b2 vaccine doses between March and May 2021. Blood samples were collected before the first vaccination (S0), before the second vaccination (S1), 4 weeks after the second vaccination (S2), and 6 months after the second vaccination (S3). anti-RBD antibodies were measured using the Architect SARS-CoV-2 IgG II Quant (Abbott Laboratory) and Elecsys anti-SARS-CoV-2 S (Roche Diagnostics) assays. Results Among the 385 participants, the geometric mean antibody titers (GMTs) on the Architect assay (AU/mL) were 7.5, 693, 7007, and 1030 for S0, S1, S2, and S3, respectively. The corresponding GMTs on the Elecsys assay (U/mL) were 0.40, 24, 928, and 659, respectively. The GMT ratio (S3/S2) was 0.15 on the Architect and 0.71 on the Elecsys assay. The correlation between antibody titers measured with the two assays were strong at all time points after vaccination (Spearman's correlation coefficient: 0.74 to 0.86, P < 0.01 for all). GMT was significantly lower in the older age group after vaccination (P < 0.01), with no significant differences according to sex. Seroprotection (≥5458 AU/mL on the Architect assay and ≥ 753 U/mL on the Elecsys) at each time point was 0 %, 1 %, 67 %, and 1 % on the Architect assay and 0 %, 1 %, 62 %, and 43 % on the Elecsys, respectively. Conclusions Two BNT162b2 vaccine doses resulted in adequate anti-RBD antibody response, which varied by age. As the two assays showed different kinetics, the results of single immunoassays should be interpreted with caution.

Abstract
Objective To examine the effect of the coronavirus disease 2019 (COVID-19) lockdown on lifestyle factors and psychological stress in patients with inflammatory bowel disease (IBD). Methods A retrospective study was conducted on patients with IBD in Japan 2 months after the initiation of the first state of emergency (June 16 to August 21, 2020). A self-reported questionnaire was used to collect data, and lifestyle factors and psychological stress levels before and after the state of emergency were compared. Patients Patients with IBD who were followed up regularly at Osaka City University Hospital from June 16 to August 21, 2020, were included and were classified into elderly (≥65 years old) and non-elderly groups (<65 years old). Results The study sample comprised 451 responders (241, ulcerative colitis; 210, Crohn's disease; 0, COVID-19). The sleep duration increased, whereas the exercise, working, and walking durations decreased during the COVID-19 lockdown. The proportion of patients with psychological stress due to COVID-19, those with an inability to exercise, and those staying indoors increased significantly during COVID-19 lockdown. Lifestyle factors changed more markedly in non-elderly patients, those who were more stressed due to COVID-19, those with the inability to exercise, and those staying indoors during COVID-19 lockdown. Among elderly patients, no significant changes were identified in stress-causing factors. Conclusion The COVID-19 lockdown affected lifestyle factors and psychological stress in patients with IBD, particularly non-elderly patients. These findings may be helpful in suggesting favorable lifestyle changes for patients with IBD.

Abstract
BACKGROUND In Japan, a monovalent mumps vaccine is provided on a voluntary basis. Due to public concerns over post-vaccination aseptic meningitis, the vaccination coverage is not high enough. The present study investigated the incidence of adverse events, including aseptic meningitis, after Torii strain-derived mumps vaccination. METHODS This retrospective, observational study used data collected by a vaccine manufacturer regarding adverse events following mumps vaccinations at medical institutions between 1992 and 2018. In addition, the number of Torii strain-derived mumps vaccines shipped each year was obtained. The incidence (per 100,000 doses) and 95% confidence intervals (CIs) were calculated for all adverse events and each adverse event, categorized as aseptic meningitis, encephalitis, mumps, mumps complications, and others. RESULTS During the study period, 8,262,121 mumps vaccine doses were shipped, and 688 subjects reported adverse events. The incidence for all adverse events (per 100,000 doses) was 8.33, and the incidence was 4.19 for aseptic meningitis, 0.33 for encephalitis, 0.80 for mumps, 0.25 for mumps complications, and 3.78 for others. The incidence of aseptic meningitis (per 100,000 doses) was 7.90 (95% CI: 5.61-10.18) between 1998 and 2000 but declined by half, to 3.91 (2.46-5.36), between 2001 and 2003. The most recent incidence (per 100,000 doses) of aseptic meningitis, for the period 2016 to 2018, was 2.78 (1.94-3.62). CONCLUSION The incidence of post-vaccination aseptic meningitis has declined significantly since 2001, and the incidence has remained stable at fewer than 3 cases per 100,000 doses since 2010. Multiple factors might have contributed to the decline in aseptic meningitis incidence, including (i) lowered misclassification of aseptic meningitis resulting from echovirus infection; (ii) changes in the vaccine manufacturing process in 2000; and (iii) publication in 2008 of the recommendation for vaccination of children at 1 year of age.

Abstract
BACKGROUND Primary biliary cholangitis (PBC) is considered to be caused by the interaction between genetic background and environmental triggers. Previous case-control studies have indicated the associations of environmental factors (tobacco smoking, a history of urinary tract infection, and hair dye) use with PBC. Therefore, we conducted a multicenter case-control study to identify the environmental factors associated with the development of PBC in Japan. METHODS From 21 participating centers in Japan, we prospectively enrolled 548 patients with PBC (male/female = 78/470, median age 66), and 548 age- and sex-matched controls. These participants completed a questionnaire comprising 121 items with respect to demographic, anthropometric, socioeconomic features, lifestyle, medical/familial history, and reproductive history in female individuals. The association was determined using conditional multivariate logistic regression analysis. RESULTS The identified factors were vault toilet at home in childhood [odds ratio (OR), 1.63; 95% confidence interval (CI), 1.01-2.62], unpaved roads around the house in childhood (OR, 1.43; 95% CI, 1.07-1.92), ever smoking (OR, 1.70; 95% CI, 1.28-2.25), and hair dye use (OR, 1.57; 95% CI, 1.15-2.14) in the model for lifestyle factors, and a history of any type of autoimmune disease (OR, 8.74; 95% CI, 3.99-19.13), a history of Cesarean section (OR, 0.20; 95% CI, 0.077-0.53), and presence of PBC in first-degree relatives (OR, 21.1; 95% CI, 6.52-68.0) in the model for medical and familial factors. CONCLUSIONS These results suggest that poor environmental hygiene in childhood (vault toilets and unpaved roads) and chronic exposure to chemicals (smoking and hair dye use) are likely to be risk factors for the development of PBC in Japan.

Abstract
Background: The government of Japan declared a state of emergency on April 16, 2020, owing to the coronavirus disease 2019 (COVID-19) pandemic. The subsequent lockdown altered lifestyles and worsened mental illnesses. Inflammatory bowel disease (IBD) is an intestinal disorder that is affected by environmental factors. Therefore, we aimed to assess the effects of COVID-19 and the state of emergency on the lifestyle and disease activity of patients with IBD. Methods: We conducted a questionnaire survey on patients with IBD from June 16 to August 21, 2020 during their regular follow-up at our hospital, 2 months after the state of emergency was declared. Results: Overall, 241 patients with ulcerative colitis (UC) and 210 with Crohn's disease (CD) completed the survey, of which 82 (34%) and 97 (46%) patients, respectively, reported disease exacerbation within 2 months after the lockdown. Multivariate logistic regression analysis identified age at enrollment (odds ratio, OR 0.98, 95% CI 0.96-0.99; P < 0.05), sleep hours (OR, 0.74; 95% CI, 0.57-0.97; P < 0.05), and increased stress due to the COVID-19 pandemic (OR, 6.06; 95% CI, 1.79-20.50; P < 0.01) as independent factors associated with UC exacerbation. Patients with exacerbated CD were younger at CD onset and had higher patient-reported outcome 2 scores before the state of emergency than patients with non-exacerbated CD. On multivariate analysis, age (OR, 0.97; 95% CI, 0.95-0.99; P < 0.01) and active disease before the state of emergency (OR, 2.20; 95% CI, 1.23-3.95; P < 0.01) were independently associated with CD exacerbation. Conclusions: Improving sleep quality and preventing psychological stress may be crucial in IBD management during a pandemic, especially in young patients.

Abstract
Abstract
Background
The prevalence of Crohn’s disease is increasing in Japan, but risk factors for this disease have yet to be characterized. A recent study using mice, indicated that Klebsiella strains in the oral cavity may be associated with inflammatory bowel disease. We investigated the association between oral hygiene and Crohn’s disease onset.
Methods
We conducted a multicenter case-control study and compared oral hygiene in 69 patients with newly diagnosed Crohn’s disease to that in 113 control patients (patients with other diseases matched for institution, age, and sex). The exposure variables were number of teeth, use of dentures, implant treatment, and frequency of brushing. A conditional logistic model was used to calculate odds ratios and 95% confidence intervals of these factors for Crohn’s disease onset.
Results
The decreased odds ratios of brushing teeth were observed with increasing daily frequency (trend for p = 0.039), with 0.52 (0.20–1.33) for twice daily brushings and 0.26 (0.07–0.97) for three or more daily brushings, (reference category: brushing no or once a day). No other oral hygiene factors were associated with the onset of Crohn's disease.
Conclusions
Our findings suggest that frequent brushing may have a protective association with the development of Crohn's disease.
Key messages
This result may provide a clue to the possible involvement of oral bacteria in the development of inflammatory bowel disease.

Abstract
Abstract
Background
In Japan, mumps vaccination coverage is low, since it is a voluntary vaccination. In this situation, the number of mumps cases as reported by pediatric sentinel hospitals suggests the occurrence of periodical mumps outbreaks.
Methods
To examine the annual incidences of mumps and mumps-related complications, we analyzed data from the health insurance reimbursement database for subscribers aged 0-64 years between 2005 and 2017. Cases with mumps and mumps-related complications including meningitis, orchitis, deafness, were extracted according to ICD-10 codes entered into the disease section for health insurance reimbursement.
Results
During the 13 year period, 68,307 of 5,209,660 subjects were reimbursed for mumps, with an incidence of 325 per 100,000 person-years (95% confidence interval (CI): 323-328). Among the 68,307 mumps cases, 787 were reimbursed for mumps-related complications, with an incidence of 11.5 per 1,000 mumps cases (95% CI: 10.7-12.4). Incidence of mumps-related complications (per 1,000 mumps cases) was highest for orchitis (6.6), followed by meningitis (5.8), deafness (1.3), pancreatitis (0.5), and encephalitis (0.3). Mumps incidence was highest among children aged 0-5 years, while incidence of mumps-related complications was highest among adults aged 26-35 years.
Conclusions
In Japan, the disease burden of mumps remains high among adults, as well as children.
Key messages
To reduce the disease burden of mumps among all ages in Japan, immunization in childhood is required. A national immunization program for children would result in high vaccination coverage and lower disease burden.

Abstract
Abstract
Background
Norovirus infection and Clostridioides difficile infection (CDI) are major causes of acute infectious diarrhea at medical facilities. “Geriatric intermediate care facilities” are a type of medical facility that tend to the daily life needs of elderly Japanese people. However, there is no research about norovirus- or CDI-related diarrhea at Japanese geriatric intermediate care facilities.
Methods
This prospective cohort study included 1445 residents at 10 geriatric intermediate care facilities in Osaka between November 2018 and October 2019. The study subjects were followed regarding the occurrence of acute infectious diarrhea and the results of rapid diagnostic tests for norovirus and CDI. We calculated incidence rates and hazard ratios (HR) with 95% confidential intervals (CI) to identify the risk factors of infectious diarrhea.
Results
Thirty-seven residents developed diarrhea during the observation period, although none of them was positive for norovirus or CDI. The total incidence rate was 1.21/10,000 person-days (95%CI: 0.82-1.60). Compared with residents aged 87-91 years, those aged ≤ 80 years had a significantly higher risk of diarrhea (HR = 3.85, 95%CI: 1.27-11.66). Moreover, residents with thyroid diseases had a significantly higher risk of diarrhea than those without thyroid disease (HR = 5.33, 95%CI: 2.32-12.25).
Conclusions
The incidence of acute infectious diarrhea is relatively low. However, residents who are < 80 years old and those with thyroid diseases are more likely to develop diarrhea.
Key messages
We describe the situation of acute infectious diarrhea at Japanese geriatric intermediate care facilities

Abstract
The vaccine confidence index in Japan is one of the lowest worldwide. This study aimed to examine the proportion of COVID-19 vaccine hesitancy in the Japanese population using a larger sample and more robust statistical methods than previously, and to identify factors associated with vaccine hesitancy. We conducted a nationwide, cross-sectional Internet survey on 8–26 February 2021, and calculated the proportion and odds ratios for vaccine hesitancy. Among 23,142 responses analyzed, the proportion of COVID-19 vaccine hesitancy was 11.3% (10.9–11.7%). The proportion was higher among younger respondents and female respondents, and especially among younger female respondents (15.6%) compared with the lowest proportion among older male respondents (4.8%). The most cited reason for not getting vaccinated was concerns about adverse reactions in more than 70% of the respondents. The proportion of COVID-19 vaccine hesitancy in Japan was comparable to that in previous studies overseas, and the proportion among younger respondents was more than double that among older respondents. Factors associated with the hesitancy were female sex, living alone, low socioeconomic status, and presence of severe psychological distress, especially among older respondents. Thus, adequate measures should be taken to ensure that vaccines are delivered to people with these factors.

Abstract
BACKGROUND Hepatocellular carcinoma develops in some patients with hepatitis C virus (HCV), even after achieving sustained virological response (SVR). AIMS We examined factors associated with liver disease progression in a prospective cohort study of SVR patients. METHODS Participants were patients who had visited a hospital for clinical follow-up of chronic HCV infection in 2005 and had reached SVR as a result of subsequent antiviral treatment. Baseline information including lifestyle and dietary habits before SVR was collected in 2005 using self-administered questionnaires, and clinical information before SVR was collected from medical records in 2005. Study outcome was liver disease progression such as liver cirrhosis, hepatocellular carcinoma, and/or liver disease-related death after SVR. Proportional hazard models were employed to calculate hazard ratios (HRs) and 95% confidence intervals for each variable. RESULTS Of 180 SVR patients, 27 patients (15%) showed liver disease progression after SVR: 26 (14%) were diagnosed with liver cirrhosis, two (1%) with hepatocellular carcinoma, and/or one (0.6%) with liver-disease-related death. Besides older age at SVR (HR = 11.9, P < 0.01) and aspartate aminotransferase-to-platelet ratio index score ≥ 1.0 before SVR (HR = 2.63, P = 0.03), alcohol drinkers before SVR (HR = 2.82, P = 0.06) were suggested to be associated with liver disease progression after SVR, whereas higher consumption of vitamin B12 before SVR showed a decreased HR for liver disease progression (HR = 0.41, P = 0.09). CONCLUSIONS Alcohol drinking might be associated with liver disease progression, whereas vitamin B12 intake might have protective effects against liver disease progression after eradication of HCV. Further studies are needed to confirm these findings.

Abstract
BACKGROUND Dietary fatty acids can affect chronic intestinal inflammation and have been reported to be associated with the development of ulcerative colitis (UC), mainly in Europe and the United States. The association of dietary intake of fatty acids and the risk for UC was investigated in Japan, where dietary habits lead to lower meat and higher fish consumption than in Western countries. METHODS A multicenter case-control study of 83 newly diagnosed patients with UC and 128 age- and sex-matched control patients in the hospital was conducted from 2008 to 2014. Dietary fatty acid intake in the preceding 1 month and 1 year were examined using a self-administered diet history questionnaire that was developed for Japanese people. RESULTS About 92% of patients had experienced the first symptoms of UC within the preceding 11 months. Regarding dietary habits in the preceding year, the risk for UC was significantly decreased in patients who consumed n-6/n-3 polyunsaturated fatty acids at a ratio of ≥5.2 (odds ratio [OR] = 0.26; 95% confidence interval [CI], 0.10-0.68). Conversely, an increased risk for UC was observed in the highest tertiles of consumption of docosahexaenoic acid (OR = 7.22; 95% CI, 2.09-24.95), eicosapentaenoic acid (OR = 6.91; 95% CI, 1.88-25.44), and docosapentaenoic acid (OR = 4.83; 95% CI, 1.56-14.95). CONCLUSIONS The ratio of n-6/n-3 polyunsaturated fatty acid intake was associated with a decreased risk for UC development. However, high intakes of docosahexaenoic acid, eicosapentaenoic acid, and docosapentaenoic acid may increase the risk for UC development.

Abstract
OBJECTIVE To determine the appropriate initial ventilatory mode for neonatal congenital diaphragmatic hernia (CDH) by comparing patient prognosis following conventional mechanical ventilation (CMV) versus high-frequency oscillatory ventilation (HFO). STUDY DESIGN This multicenter retrospective cohort study was performed at 15 participating hospitals in Japan between 2011 and 2016. The 328 eligible CDH infants were classified into CMV (n = 78) and HFO groups (n = 250) to compare mortality and incidence of bronchopulmonary dysplasia (BPD). Propensity score matching was applied to reduce confounding by indication. RESULT While crude mortality was significantly higher in the HFO than the CMV group, adjusted odds ratio (OR) did not show significant difference in mortality between groups (OR of HFO group: 0.98, 95% confidence interval (CI): 0.57-1.67). Adjusted OR of BPD incidence showed no significant difference between groups (OR of HFO group: 1.66, 95%CI: 0.50-5.49). CONCLUSION Initial ventilatory mode in CDH patients, whether CMV or HFO, does not affect prognosis.

Abstract
Background Mumps vaccination coverage is low in Japan, partly because of its voluntary nature. Although pediatric cases of mumps virus infection are captured by the National Epidemiological Surveillance of Infectious Diseases program under the Infectious Disease Law, there are currently no data regarding the occurrence of mumps and its complications in adults. Methods We investigated the annual incidence rates of mumps and its complications based on health insurance reimbursement data for 5,209,660 individuals aged 0–64 years for 2005–2017, obtained from JMDC Inc., to estimate the mumps-related disease burden during this period. Results There were three mumps outbreaks (2006, 2010, and 2016) during 2005–2017. The annual incidence of mumps was highest in individuals aged 0–5 years (808–3,792 per 100,000 persons), followed by those aged 6–15 years (658–2,141 per 100,000 persons). The incidence of mumps was higher in females than in males (male/female ratio, 0.90). Among mumps-related complications, the overall incidence (per 1,000 mumps cases) was highest for orchitis (6.6), followed by meningitis (5.8), deafness (1.3), pancreatitis (0.5), and encephalitis (0.3). No cases of oophoritis were noted. The overall incidence of mumps-related complications was 2.5 times higher in males than in females. Conclusions This study revealed the disease burden due to mumps and its complications in Japan during 2005–2017. These data suggest the need for mumps-prevention measures in adolescents and adults, as well as in children.

Abstract
OBJECTIVE The Japanese national immunization program recommends that children receive 4 doses of acellular pertussis vaccine between 3 months and 2 years of age. Nevertheless, the number of pertussis cases is increasing in elementary school children aged 6-12 years. Therefore, a test-negative case-control study was conducted to assess the effectiveness of the pertussis vaccine program. METHODS Subjects included children aged ≥3 months who visited a collaborating hospital due to pertussis-specific cough between October 2017 and November 2019. All subjects underwent diagnostic tests for pertussis, and those diagnosed as positive were regarded as cases. Subjects diagnosed as pertussis-negative were classified as controls. Vaccination history was collected using a questionnaire administered to parents with reference to immunization records. Logistic regression models were employed to calculate the odds ratio (OR) and 95% confidence interval for laboratory-confirmed pertussis. RESULTS Of 187 recruited subjects (120 cases and 67 controls), questionnaire responses were obtained for 145 subjects (95 cases and 50 controls). Compared with unvaccinated subjects, the vaccine effectiveness (VE) of 4 doses was 70% among all subjects and reached to 90% with marginal significance among subjects under 6 years of age. However, among school-aged subjects, the VE was not suggestive of protection against pertussis (VE: 8%). For vaccinees given 4 doses, the OR for developing pertussis increased significantly with longer duration since the fourth dose (compared with <4.5 years, OR of 6.0-8.2 years = 5.74; OR of ≥8.3 years = 3.88; P for trend by duration < 0.01). CONCLUSION Effectiveness of administering 4 doses of pertussis vaccine during infancy decreases with time passed since the fourth dose. This regimen does not protect school-aged children against pertussis.

Abstract
Background and Aim The purpose of this study was to identify lifestyle risk factors, such as cigarette smoking and alcohol consumption, in relation to the development of hepatocellular carcinoma (HCC) among chronic hepatitis C patients who have achieved a sustained virologic response (SVR). Methods This cross-sectional study was conducted between 2014 and 2017 using self-administered questionnaires and medical information at two tertiary hospitals in Osaka, Japan. Study subjects were chronic hepatitis C patients who had achieved SVR without HCC following antiviral treatment that was completed more than 1 year earlier. A logistic regression model was used to calculate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the development of post-SVR HCC for each factor. Results Of 202 participants, 18 patients were diagnosed with post-SVR HCC. After considering potential confounders, former drinkers at the time of SVR (OR, 9.51; 95% CI, 1.08-83.90) and patients with a history of gastric or duodenal ulcer (OR, 4.14; 95% CI, 1.37-12.46) were significantly associated with HCC. In addition, among patients with severe fibrosis, current smokers at the time of SVR had an increased OR for HCC compared with never smokers, with marginal significance (OR, 5.61; 95% CI, 0.97-32.63). Conclusions In chronic hepatitis C patients with severe fibrosis, continuing smoking after achieving SVR could be a risk factor for post-SVR HCC. The relationship between gastric or duodenal ulcer history and post-SVR HCC should be investigated further.

Abstract
OBJECTIVES Pouchitis is a major complication after restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC). Although there have been many investigations of the neutrophil-to-lymphocyte ratio (NLR) in various diseases, its role in predicting the development of pouchitis remains unclear. We aimed to evaluate the clinical utility of the NLR for predicting the development of pouchitis after IPAA in UC patients. MATERIALS AND METHODS UC patients who underwent IPAA at Osaka City University Hospital between May 2006 and March 2019 were included. The incidence of pouchitis was estimated using the Kaplan-Meier method. Potential preoperative, intraoperative, and postoperative predictors for pouchitis, including various demographic and clinical variables, were analyzed. The combined impact of the NLR and other known prognostic factors were investigated using Cox proportional hazard regression with inverse probability of treatment weighting (IPTW). RESULTS Forty-nine patients with UC who underwent IPAA were included. The median follow-up period was 18.3 months (interquartile range: 10.7-47.2 months). Eighteen patients (36.7%) developed pouchitis. The incidence of pouchitis was 19.2%, 32.6%, and 45.9% at 1, 2, and 5 years, respectively. NLR was significantly associated with the development of pouchitis in the univariate Cox regression analysis (hazard ratio (HR), 1.14; 95% confidence interval (CI), 1.01-1.28; P = 0.03). The NLR cutoff value of 2.15 was predictive of the development of pouchitis according to receiver operating characteristic analysis (specificity: 67.7%, sensitivity: 72.2%). The incidence of pouchitis was significantly lower in the low NLR group than that in the high NLR group (P = 0.01, log-rank test). Cox regression analyses using IPTW also identified NLR as a prognostic factor for the development of pouchitis by statistically adjusting for background factors (HR, 3.60; 95% CI, 1.31-9.89; P = 0.01). CONCLUSIONS NLR may be a novel and useful indicator for predicting the development of pouchitis after IPAA in UC and should be introduced in clinical practice.

Abstract
Background Mumps deafness causes serious problems, and incidence data are needed to identify its disease burden. However, such data are limited, and the reported incidence is highly variable. Nationwide studies in Japan with a large age range are lacking. Methods This was a retrospective observational investigation of the 2005–2017 mumps burden using employment-based health insurance claims data. Data were analyzed for 5,190,326 people aged 0–64 years to estimate the incidence of mumps deafness. Results Of 68,112 patients with mumps (36,423 males; 31,689 females), 102 (48 males; 54 females) developed mumps deafness—an incidence of 15.0 per 10,000 patients (1 in 668 patients). Fifty-four (52.9%) patients had mumps deafness in childhood (0–15 years), and 48 (47.1%) had mumps deafness in adolescence and adulthood (16–64 years); most cases occurred in childhood, the peak period for mumps onset. The incidence of mumps deafness per 10,000 patients was 73.6 in adolescence and adulthood, 8.4 times higher than the incidence of 8.8 in childhood (P < 0.001). In childhood, the incidence of mumps deafness was 7.2 times higher among 6–15-year-olds (13.8; 95% CI, 10.2–18.2) than among 0–5-year-olds (1.9; 95% CI, 0.6–4.5), and this difference was statistically significant (P < 0.001). No sex difference was observed. Conclusions The incidence of mumps deafness per 10,000 patients aged 0–64 years was 15.0 (1 in 668 patients). A secondary risk of deafness following mumps virus infection was identified not only for children, but also for adolescents and adults.

Abstract
PURPOSE To date, there is no compelling evidence of the optimal timing of surgery for congenital diaphragmatic hernia (CDH). This study aimed to establish the optimal timing of surgery in neonates with isolated left-sided CDH. METHODS This multicenter cohort study enrolled 276 patients with isolated left-sided CDH at 15 institutions. Based on the timing of surgery, the patients were classified into four groups [< 24 h (G1), 24-47 h (G2), 48-71 h (G3), and ≥ 72 h (G4)]. The clinical outcomes were compared among the groups using a logistic regression model, after adjusting for potential confounders, such as disease severity. RESULTS Multivariate analyses showed that G2 also had a lower mortality rate than the other groups. In mild and severe cases, there were no significant differences in mortality across the four groups. In moderate cases, G2 resulted in significantly increased survival rates, compared with G1. CONCLUSION The study results suggest that surgery within 24 h of birth is not recommended for patients with moderate severity CDH, that there is no benefit in the delay of surgery for more than 72 h in mild severity CDH patients, and that there is no definite optimal time to perform surgery in severe cases of CDH.

BACKGROUND For the 2017-18 influenza season, A/Saitama/103/2014 (CEXP-002) (Saitama strain) was antigenically more similar to prior circulating strains than A/Hong Kong/4801/2014 (X-263) (Hong Kong strain) in a ferret model and was selected as the A(H3N2) vaccine virus strain in Japan. However, the Saitama strain grew poorly, and the Japanese government switched to the Hong Kong strain, raising public concerns of poor effectiveness. To enhance understanding of the correlation between antigenicity in experimental models and immunogenicity, as a surrogate measure of vaccine effectiveness, in the human population, we compared the immunogenicity of specially-prepared single dose monovalent influenza A(H3N2) vaccines containing the Saitama or the Hong Kong strain. METHODS A randomized controlled trial of 100 healthy adults aged 20-64 years (n = 50/group) was conducted. Virus neutralization assay was performed on sera from days 0 (pre-vaccination) and 21 (post-vaccination). Geometric mean titer (GMT), mean fold rise (MFR), seroconversion proportion (SCP), and seroprotection proportion (SPP) were calculated for vaccine strains and a representative circulating A(H3N2) virus strain (A/Osaka/188/2017). RESULTS For the Hong Kong strain, post-vaccination GMT was significantly higher in the Hong Kong vaccine recipients (1:546 vs 1:260, p < 0.01), but MFR, SCP, and SPP were similar for both vaccine groups. For the Saitama strain, post-vaccination GMT (1:116 vs 1:61, p = 0.01) and SPP (86% vs 68%, p = 0.03) were significantly higher in the Hong Kong vaccine recipients, but MFR and SCP were similar for both vaccine groups. Against A/Osaka/188/2017, post-vaccination GMT and MFR were similar in both vaccine groups, but SCP (32% vs 4%, p < 0.01) and SPP (28% vs. 6%, p < 0.01) were significantly higher in the Hong Kong vaccine recipients. CONCLUSION The Hong Kong vaccine induced better or equivalent immunogenicity in comparison to the Saitama vaccine. Our trial showed that antigenic similarity in experimental models does not necessarily correlate with immunogenicity in the human population. CLINICAL TRIAL REGISTRATION UMIN000029293.

Abstract
Station staff may be at high risk for influenza due to high frequency contact with other people. We examined the risk of influenza by occupational group in a railway company. A retrospective observational study was conducted among employees at a branch office of a railway company in eastern Japan, located in a metropolitan area, for 2012/13, 2013/14, and 2014/15 influenza seasons. The study population included employees who had received influenza vaccination for the season in question and the previous season. Outcome was defined as self-reported influenza illness during the respective season, identified through the vaccine screening questionnaire in the following season. Study participants included employees whose outcome information could be obtained. Standardized morbidity ratios (SMRs) by occupational group (station staff, engineers, train crew) for each season were calculated. For 2012/13, 2013/14, and 2014/15 seasons, attack rates were 4.7% (19/403), 5.2% (21/407), and 7.8% (31/397), respectively. Among the participants, SMRs of station staff were lower in the 2012/13 (SMR = 57; 95% confidence intervals [CI] = 18-133) and 2014/15 (SMR = 75; 95%CI = 36-138) seasons and similar to other groups in the 2013/14 season. Enhanced countermeasures, regardless of occupational group, may be effective in preventing the spread of influenza infection.

Abstract
Background Cronkhite-Canada syndrome (CCS), chronic enteropathy associated with SLCO2A1 gene (CEAS), and intestinal Behçet’s disease (BD) are classified as intractable intestinal disorders in Japan. However, the national prevalence of these diseases remains unknown. We performed a nationwide survey to estimate the patient numbers and prevalence rates of these diseases throughout Japan in 2017. Methods We conducted a mail-based survey targeting hospitals across Japan to estimate the annual numbers of patients with CCS, CEAS, and intestinal BD in 2017. Using a stratified random sampling method, we selected 2,979 hospital departments and asked them to report the number of patients who met specific diagnostic criteria. The total number of patients for each disease was estimated by multiplying the reported numbers by the reciprocal of the sampling rate and response rate. The corresponding prevalence rates per 1,000,000 population were calculated based on the mid-year population of Japan in 2017. Results The overall survey response rate was 68.1% (2,029 departments). The estimated numbers of patients with CCS, CEAS, and intestinal BD were 473 (95% confidence interval [CI], 357–589), 388 (95% CI, 289–486), and 3,139 (95% CI, 2,749–3,529), respectively; the prevalence rates per 1,000,000 population were 3.7 (male: 4.0; female: 3.5), 3.1 (male: 3.0; female: 3.1), and 24.8 (male: 24.5; female: 25.0), respectively. The male-to-female ratios were 1.10, 0.94, and 0.93 for patients with CCS, CEAS, and intestinal BD, respectively. Conclusions Estimates of the national prevalence of CCS, CEAS, and intestinal BD in Japan were generated and found to be higher than those previously reported.

Abstract
BACKGROUND Pregnant women are in the highest priority group for receiving influenza vaccination. However, they may be reluctant to receive the vaccination due to concerns about the influence of vaccination on the fetuses. METHODS This prospective cohort study of 10 330 pregnant women examined the safety of influenza vaccination in terms of adverse birth outcomes. Influenza vaccination during pregnancy was determined from questionnaires before and after the 2013/2014 influenza season. All subjects were followed until the end of their pregnancy. Adverse birth outcomes, including miscarriage, stillbirth, preterm birth, low birth weight, and malformation, were assessed by obstetrician reports. RESULTS Adverse birth outcomes were reported for 641 (10%) of the 6387 unvaccinated pregnant women and 356 (9%) of the 3943 vaccinated pregnant women. Even after adjusting for potential confounders, vaccination during pregnancy showed no association with the risk of adverse birth outcomes (odds ratio 0.90, 95% confidence interval 0.76-1.07). Vaccination during the first or second trimester displayed no association with adverse birth outcomes, whereas vaccination during the third trimester was associated with a decreased risk of adverse birth outcomes (odds ratio 0.70, 95% confidence interval 0.51-0.98). CONCLUSIONS Influenza vaccination during pregnancy did not increase the risk of adverse birth outcomes, regardless of the trimester in which vaccination was performed, when compared to unvaccinated pregnant women.

Abstract
BACKGROUND Almost a quarter century has passed since the first nationwide survey on ulcerative colitis (UC) and Crohn's disease (CD) was conducted in Japan. In this study, we used a nationwide survey to estimate the number of patients and prevalence of these diseases in Japan in 2014. METHODS We conducted a mail-based survey targeting hospitals to estimate the annual numbers of patients with UC and CD in 2014. Respondents were asked to report the numbers of patients who met specific diagnostic criteria for these two conditions. A stratified random sampling method was used, and a total of 3712 departments (internal medicine, surgery, pediatrics, and pediatric surgery) were selected for analysis. The overall and sex-specific annual numbers of UC and CD patients were estimated. The corresponding prevalence rates per 100,000 population were calculated by dividing the number of patients with each disease by the mid-year population of Japan in 2014. RESULTS The overall survey response rate was 56.7% (2016 departments). The estimated numbers of patients with UC and CD were 219,685 (95% confidence interval: 183,968-255,403) and 70,700 (56,702-84,699), respectively. The annual prevalence rates of UC and CD per 100,000 population were 172.9 (men: 192.3; women: 154.5) and 55.6 (men: 79.5; women: 33.1), respectively. These numbers are almost tenfold increase in comparing the previous survey (22,300 in UC and 7,400 in CD). The male-to-female ratios were 1.24 for UC and 2.40 for CD, and the UC-to-CD ratio was 3.11. CONCLUSIONS The prevalence of UC and CD in Japan has risen substantially over the past two decades, and their disease burden requires further examination.

Abstract
BACKGROUND AND AIM The prevalence of ulcerative colitis (UC) has been increasing in Japan. Trace elements, such as iron, zinc, magnesium, and copper, can cause digestive symptoms where there is a deficiency or excess. We focused on the dietary intake of trace elements and their associations with UC development. METHODS A multicenter, hospital-based case-control study was conducted in Japan. Cases were 127 newly diagnosed UC patients, and 171 age-matched and sex-matched hospital controls were recruited. We considered that UC patients had potentially changed their dietary habits due to disease symptoms. The dietary habits were investigated using a self-administered diet history questionnaire to analyze the dietary intakes and frequencies at two points, the previous 1 month and 1 year before. RESULTS In the assessment of dietary habits 1 year before, the highest intake of iron showed an increased odds ratio (OR) for UC on multivariate analysis (OR = 4.05, 95% confidence interval, 1.46-11.2, P < 0.01). The highest intake of zinc 1 year before showed a decreased OR for UC (OR = 0.39, 95% confidence interval, 0.18-0.85, P = 0.01). Intakes of magnesium and copper had no significant association with UC. Because most UC cases had experienced the first symptom of UC within the previous 11 months, these intakes at 1 year before represented an association with pre-illness dietary habits. CONCLUSION A high intake of iron has some effect on the development of UC. In contrast, a high intake of zinc has a protective effect on the development of UC.

Abstract
BACKGROUND Severe pediatric cases of hand, foot, and mouth disease (HFMD), herpangina (HA), and associated complications caused by enterovirus 71 (EV71) infection have brought substantial public health impact in Asia. This study aimed to elucidate the epidemiology of these pediatric cases in Japan. METHODS A nationwide survey was conducted using stratified random sampling of hospital pediatric departments. We estimated the number of inpatients with HFMD, HA, and associated complications between April 1 and September 30, 2010, during which EV71 was circulating predominantly. Factors associated with severe cases with ≥7 days of admission, sequelae, or outcome of death were analyzed using multivariate logistic regression. RESULTS During the 6-month epidemic period, the number of pediatric inpatients aged <15 years was about 2,900 (estimated cumulative incidence of hospitalized cases: 17.0 per 100,000 population). Severe cases were significantly associated with younger age. Compared to patients ≥5 years of age, the odds ratios (ORs) for <1 year of age and 1 to <3 years of age were 5.74 (95% confidence interval [CI], 2.14-15.4) and 2.94 (95% CI, 1.02-8.51), respectively. Elevated ORs for hyperglycemia (plasma glucose level of ≥8.3 mmol/L) on admission (OR 3.60; 95% CI, 0.94-13.8) were also observed. CONCLUSIONS Disease burden of pediatric inpatients with HFMD, HA, and associated complications in Japan was described for the first time. During an EV71 epidemic, younger age and, suggestively, hyperglycemia may have been critical factors requiring more careful treatment.

Abstract
AIM Idiopathic portal hypertension (IPH), extrahepatic portal obstruction (EHO), and Budd-Chiari syndrome (BCS) are characterized by aberrant portal hemodynamics of unknown etiology. The aim of this study was to explore trends in the descriptive epidemiology of these diseases through periodical nationwide surveys. METHODS Nationwide epidemiologic surveys were undertaken in 1999, 2005, and 2015 using the same protocol. The survey targets were selected from all departments of gastrointestinal medicine, surgery, pediatrics, and pediatric surgery in Japan by stratified random sampling according to the number of beds. We asked each department to complete a mail-back questionnaire on the annual numbers of patients with IPH, EHO, and BCS during the preceding year. RESULTS The estimated number of BCS patients increased from 280 (95% confidence interval, 200-360) in 1999 survey to 410 (300-530) in 2015 survey, whereas the number of IPH and EHO patients has remained largely unchanged during the 15 years (IPH was approximately 1000; EHO was approximately 770 in 2015 survey). The mean age at symptom onset was approximately 45 years for IPH, 30 years for EHO, and 40 years for BCS over the past 15 years. Those who described disease aggravation from the time of diagnosis accounted for approximately 10% of IPH, 15% of EHO, and 20% of BCS patients in each of the three surveys. CONCLUSIONS In Japan, the prevalence of BCS is increasing, while those of IPH and EHO appear to be stable. Clinical characteristics, including prognoses, have remained largely unchanged in the past 15 years.

Abstract
Background Nutritional status of the older people is affected by various life-style factors. Although dietary habit is one of the life-style factors, it is unknown which of older home-care recipients’ dietary habits are associated with malnutrition. The purpose of this study was to examine the association of dietary variety, as an evaluation index for dietary habits, with malnutrition in Japanese older home-care recipients. Methods This cross-sectional study was conducted in a single city, Hyogo Prefecture, Japan between July and October 2016. Three hundred thirty-three community-dwelling older care recipients (aged 65 years or older who were receiving home-visit nursing care services) were enrolled. Their nutritional status (Mini Nutritional Assessment®-short form: MNA®-SF), dietary variety (Food frequency score [FFS]), socio-demographic characteristics (age, sex, marital status, etc.), health indicators (comorbidity [Charlson Comorbidity Index] and dysphagia status [Dysphagia Severity Scale]) were assessed. The participants were classified into two groups: malnourished (0–7 points) and non-malnourished (8–14 points), according to their MNA®-SF scores. Multivariate logistic regression analysis was used to examine the factors associated with malnutrition. Results A total of 317 participants were analyzed (118 men, 199 women, median age: 84 years). Compared to the fourth (highest) quartile of FFS, odds ratios (OR) (95% confidence intervals [CI]) of the third, second, and first (lowest) quartiles of FFS were 1.08 (0.42–2.80), 1.29 (0.56–2.98), and 2.30 (1.02–5.19), respectively (p for trend = 0.049). Higher Charlson Comorbidity Index score and the presence of dysphagia were also significantly associated with malnutrition (OR: 2.08, 95% CI: 1.08–4.00 and OR: 3.86, 95% CI: 2.08–7.17, respectively). Conclusion Lower dietary variety was significantly associated with malnutrition in Japanese older home-care recipients.

Abstract
Background Infants <6 months of age are too young to receive influenza vaccine, despite being at high risk for severe influenza-related complications. Methods To examine the effectiveness of maternal influenza vaccination in preventing influenza in their infants, we conducted a prospective cohort study of 3441 infants born at participating hospitals before the 2013-2014 influenza season. At the time of recruitment, their mothers completed a questionnaire about influenza vaccination status for the 2013-2014 season. A follow-up survey was conducted after the end of the 2013-2014 season to collect information regarding influenza diagnosis and hospitalization among infants. Results During the 2013-2014 influenza season, 71 infants (2%) had influenza diagnosed, and 13 infants (0.4%) were hospitalized with influenza. Maternal influenza vaccination (especially prenatal vaccination) decreased the odds of influenza among infants. The effectiveness of prenatal vaccination was 61% (95% confidence interval, 16%-81%), whereas that of postpartum vaccination was 53% (-28%-83%). Although maternal influenza vaccination was also associated with a decreased odds of influenza-related hospitalization among infants, vaccine effectiveness (73%) did not reach statistical significance, owing to the limited number of infants hospitalized because of influenza. Conclusions The present findings indicated that pregnant women and postpartum women should receive influenza vaccination to protect their infants.

Abstract
BACKGROUND The number of patients with Crohn's disease (CD) in Japan has recently been increasing. We examined the association between environmental factors and the development of CD in Japanese focusing on passive smoking. METHODS We conducted a multicenter case-control study and compared the environmental factors of 93 cases who were newly diagnosed with CD to the environmental factors of 132 controls (hospital-, age-, and sex-matched patients with other diseases). The odds ratio (OR) of each factor for the development of CD and the 95% confidence interval (CI) were calculated using a logistic regression model. The association between the details of passive smoking history and the development of CD was examined for those who had an active smoking history "no". Odds ratios of number of passively smoked cigarettes (per day), time of passive smoking (per day) and period of passive smoking (year) were calculated using "passive smoking 'No'" as a reference. RESULTS History of appendicitis, family history of inflammatory bowel disease, and active smoking history were not significantly associated with the development of CD. Drinking history showed a decreased OR for the development of CD (0.39, 0.19-0.77). "Passive smoking Yes" showed significantly increased OR (2.49, 1.09-5.73). Regarding the association between passive smoking and the development of CD, the OR increased as the number of cigarettes per day, smoking time per day, and smoking duration increased, and there was a dose-response relationship (trend P = 0.024, 0.032, 0.038). CONCLUSIONS The association between environmental factors and the development of CD among Japanese was examined by case-control study. It was suggested that the passive smoking history may be associated to the development of CD.

Abstract
Background Older adults are vulnerable to hospitalization or death from norovirus infection, but the actual disease burden remains unknown. Therefore, we conducted a nationwide survey to estimate the number of inpatients with norovirus gastroenteritis and associated deaths among Japanese older adults. Methods We performed a nationwide two-step query targeting 4184 hospital departments selected from 17,575 departments using stratified random sampling according to the number of beds. We asked each department to complete a mail-back questionnaire on the annual numbers of inpatients with infectious gastroenteritis and associated deaths between administrative years 2012 and 2014, and the implementation status of norovirus infection testing. In a second query, we investigated the annual number of inpatients with norovirus gastroenteritis and associated deaths in departments that had reported infectious gastroenteritis inpatients in the first query. Clinical information was collected for inpatients with norovirus gastroenteritis in administrative year 2014. Results Norovirus testing for patients hospitalized for acute gastroenteritis was routinely conducted in 16% of the responding departments. Although half the departments responded that some acute gastroenteritis inpatients received such testing but others did not. In this situation, numbers of inpatients with norovirus gastroenteritis in Japan were estimated as 31,800 (95% CI: 25,700-37,900) in administrative year 2012, 21,600 (95% CI: 17,700–25,500) in administrative year 2013, and 15,700 (95% CI: 12,900–18,500) in administrative year 2014. The estimated number of associated deaths was approximately 600 in each administrative year. Factors associated with death included higher age, living in long-term care facilities, underlying illnesses such as chronic respiratory diseases, and complications such as aspiration pneumonia. Conclusions The actual number of norovirus inpatient would be higher than the estimated here due to the low rate of routinely implemented norovirus testing. Considering Japan’s rapidly aging society and the disease burden of norovirus infection among Japanese older adults, it is important to protect this high-risk population from norovirus infection.

Abstract
At present, there are few reports that have clarified the effectiveness of 23-valent pneumococcal polysaccharide vaccine (PPSV23) against all-cause pneumonia or pneumococcal pneumonia in community-acquired pneumonia (CAP) in older individuals in Japan. We conducted a hospital-based matched case-control study to investigate separately the preventive effects of PPSV23 and trivalent influenza vaccine (TIV) on all-cause CAP and pneumococcal CAP in older individuals in Japan. Cases were individuals aged 65 years or older who were newly diagnosed with CAP from October 2010 to September 2014. Two control patients with a different disease (one respiratory medicine and one non-respiratory medicine) matched for sex, age, date of outpatient visit, and medical institution were selected for each case. Odds ratios (ORs) and 95% confidence intervals (CIs) of PPSV23 and TIV for the occurrence of all-cause CAP and pneumococcal CAP were calculated using conditional and unconditional logistic regression models. The analysis included 161 cases and 308 controls from the 4-year period. The adjusted OR for the occurrence of all-cause CAP was 0.76 (95%CI = 0.44-1.32) with PPSV23 vaccination and 0.79 (95%CI = 0.50-1.25) with TIV vaccination compared with unvaccinated individuals. When the outcome index was restricted to pneumococcal CAP, the adjusted OR significantly decreased to 0.23 (95%CI = 0.08-0.66) with PPSV23 vaccination, but not with TIV vaccination (adjusted OR = 0.65, 95%CI = 0.31-1.36). PPSV23 vaccination is likely effective in reducing incidence of pneumococcal CAP in older individuals, although its preventive effect for all-cause CAP has not been achieved.

Abstract
Background In Japan, freeze-dried live attenuated varicella-zoster vaccine is available for adults aged ≥50 years to prevent herpes zoster. However, limited evidence has been accumulated regarding vaccine safety for patients with underlying illnesses, who have been considered as the high-risk group for herpes zoster. Methods A prospective cohort study of 1200 healthy adults and 300 patients with underlying illnesses such as malignancy, diabetes mellitus, autoimmune diseases, and renal diseases was conducted. All subjects were vaccinated and then their adverse events (AEs) were followed for 28 days after vaccination. Key safety measures included any AEs, severe AEs (SAEs), and vaccine-related AEs such as injection-site AEs and systemic AEs. The frequencies and 95% confidence intervals of AEs were calculated. Results During the follow-up period, 2 SAEs (bone fracture and acute cholecystitis) among healthy adults and 1 SAE (disseminated mycobacteriosis) among patients with underlying illnesses were reported, although none of them was diagnosed as vaccine-related. Vaccine-related AEs were reported in 42% of healthy adults and patients with underlying illnesses, and the proportions were similar between the groups. The most frequent AEs were injection-site AEs in both groups (i.e., 41 and 39%), and systemic AEs were observed in 4% of both groups. Only among healthy adults, those with a history of herpes zoster were more likely to report injection-site AEs than those without a history of herpes zoster (53% vs 39%). Conclusions The present study confirmed the safety of freeze-dried, live attenuated varicella-zoster vaccine even in patients with underlying illnesses. A history of herpes zoster might be related to development of injection-site AEs in healthy adults. Trial registration The study was prospectively registered on Japic-Clinical Trials Information as JapicCTI-163415 on October 31, 2016.

Abstract
Nagoya City initiated a public subsidy program for mumps vaccination using either the Torii or Hoshino strains in August 2010. To determine the effects of the program, we used publicly available information from Nagoya City to investigate the changes in immunization rates and numbers of patients who developed post-immunization adverse reactions, including post-vaccinal aseptic meningitis, in the 7 years since its initiation. We also investigated the numbers of mumps patients reported by sentinel sites in a national database during this period. The immunization rate in one-year-old children increased from 24.3% before the program to 91.0% after 7 years. The mean numbers of reported mumps cases per sentinel site in one-year-old to preschool children-the age groups targeted by the program- were 12.9 in the 7 years before the program and 4.93 in the 7 years after initiation of the program, showing a significant decrease of 1/2.6 (p = 0.01). The number of vaccinations during the 6.5-year period was 140,316, with only one case of aseptic meningitis reported (0.7 cases/100,000 vaccinations). No other serious adverse reactions were observed. The present findings demonstrate that the public subsidy program in Nagoya City is an effective and safe measure against mumps in children.
