Abstract
Objectives This study focused on food after weaning and examined the children's diet and home environmental factors that influence parents' concerns during health checkup for infants (aged 1.6 and 3 years).Methods In the analysis, 646 participants, excluding invalid responses, who cooperated with the survey during health checkup for 1.6- and 3-year-old in the Tohoku, Chubu, and Chugoku regions from March 2019 to January 2020, were included. The survey included 56 items of dietary, lifestyle, and health concerns (yes/no answers), child attributes, and frequency of food intake (six options, 18 types). Concern factors were extracted by factor analysis. The association between the worry scores and each factor was analyzed.Results The 1.6- and 3-year-olds were associated with high scores for (health awareness and lifestyle) and low fruit intake, high salty snacks intake, and low subjective economic status, high scores for (diet content and atmosphere) and low intakes of carotene-rich vegetables, other vegetables, seaweed, and fruits, high scores for (interest and motivation in food) and low carotene-rich vegetables intake, high scores for (food experience and behavior) and high cereals (bread) intake, low subjective economic status. The 3-year-olds were associated with high scores and being boys.Conclusion We extracted four worry factors that parents with children after the weaning period have and clarified the factors related to each factor and group characteristics.

Factors associated with smoking behaviour changes during the COVID-19 pandemic in Japan: a 6-month follow-up study. Tob Control 2024; 33:287-294. [PMID: 37616062 DOI: 10.1136/tc-2022-057353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 08/10/2022] [Indexed: 11/04/2022]
Abstract
BACKGROUND Smoking behaviour may have changed due to the COVID-19 pandemic, the April 2020 revised smoke-free policy and the high prevalence of heated tobacco product (HTP) use in Japan (10.9% in 2020). This study examined the association between these three events and smoking behaviour changes using 6-month follow-up data from before and during the pandemic. METHOD Using longitudinal data from an internet survey conducted in February 2020 (baseline) and follow-up in August to September 2020, prevalence ratios (PR) and 95% confidence intervals (95% CIs) for smoking behaviour changes (increase and quit) were calculated using multivariable Poisson regression with adjustments for potential covariates including three event-related five factors: fear of COVID-19, living in a COVID-19 endemic area, workplace smoking rules, self-imposed smoking rules at home and type of tobacco use (cigarette only/HTP only/dual use). A smoker who reported an increase in smoking intensity in the last month was defined as an increase. A smoker who had stopped both cigarettes and HTPs at follow-up was defined as a quit. RESULTS We analysed 1810 tobacco users (1448 males (80%); mean age 50.8 years±13.2 SD). At baseline, 930 participants used cigarettes only, 293 HTPs only and 587 both. While 214 (11.8%) users increased smoking intensity, 259 (14.3%) quit both tobacco products. Those who feared COVID-19 were less likely to quit (PR=0.77, 95% CI 0.68 to 0.95), while living in a COVID-19 endemic area was not associated with either smoking behaviour change. Workplace smoking rules were not associated with either smoking behaviour change, but those with no home smoking ban were less likely to quit. Compared with cigarette-only users, HTP-only users were more likely to quit (PR=1.57, 95% CI 1.17 to 2.11), while dual users were more likely to increase smoking intensity (PR=1.35, 95% CI 1.01 to 1.79). CONCLUSION During the pandemic, dual cigarette and HTP use increased smoking intensity, whereas HTP-only use was associated with quitting but fear of COVID-19 and not having a home smoking ban made it harder to quit.

Alcohol consumption, multiple Lugol-voiding lesions, and field cancerization. DEN OPEN 2024; 4:e261. [PMID: 37409321 PMCID: PMC10318126 DOI: 10.1002/deo2.261] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 06/02/2023] [Accepted: 06/12/2023] [Indexed: 07/07/2023]
Abstract
The development of multiple squamous cell carcinomas (SCC) in the upper aerodigestive tract, which includes the oral cavity, pharynx, larynx, and esophagus, is explained by field cancerization and is associated with alcohol consumption and cigarette smoking. We reviewed the association between alcohol consumption, multiple Lugol-voiding lesions, and field cancerization, mainly based on the Japan Esophageal Cohort study. The Japan Esophageal Cohort study is a prospective cohort study that enrolled patients with esophageal SCC after endoscopic resection. Enrolled patients received surveillance by gastrointestinal endoscopy every 6 months and surveillance by an otolaryngologist every 12 months. The Japan Esophageal Cohort study showed that esophageal SCC and head and neck SCC that developed after endoscopic resection for esophageal SCC were associated with genetic polymorphisms related to alcohol metabolism. They were also associated with Lugol-voiding lesions grade in the background esophageal mucosa, the score of the health risk appraisal model for predicting the risk of esophageal SCC, macrocytosis, and score on alcohol use disorders identification test. The standardized incidence ratio of head and neck SCC in patients with esophageal SCC after endoscopic resection was extremely high compared to the general population. Drinking and smoking cessation is strongly recommended to reduce the risk of metachronous esophageal SCC after treatment of esophageal SCC. Risk factors for field cancerization provide opportunities for early diagnosis and minimally invasive treatment. Lifestyle guidance of alcohol consumption and cigarette smoking for esophageal precancerous conditions, which are endoscopically visualized as multiple Lugol-voiding lesions, may play a pivotal role in decreasing the incidence and mortality of esophageal SCC.

Associations between school-based fluoride mouth-rinse program, medical-dental expense subsidy policy, and children's oral health in Japan: an ecological study. BMC Public Health 2024; 24:762. [PMID: 38475804 DOI: 10.1186/s12889-024-18156-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 02/19/2024] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND Dental caries are a common non-communicable disease among children. As a public health measure at the prefectural level, school-based fluoride mouth-rinse (S-FMR) program, medical/dental expense subsidy policies, and other factors may reduce the incidence of dental caries and tooth loss. Prefectures focusing on promoting oral health policies may promote both, but the interaction effect of implementing both subsidy policies and S-FMR at the prefectural level on caries prevention has not yet been examined. METHODS We conducted an ecological study using two-wave panel data, prefecture-level aggregated data in Japan for 2016 and 2018. Coefficient and 95% confidence intervals (CI) were calculated for the dependent variables for oral health using mixed-effects linear regression analysis adjusted for possible confounders. Two dependent variables were used; the standardized claim ratio (SCR) of deciduous tooth extraction and 12-year-olds' decayed, missing, or filled permanent teeth (DMFT). Four independent variables were S-FMR, the SCR of dental sealants, prefectural income per person, and subsidy policy in three models: co-payment until children enter elementary school (n = 23), no co-payment until children enter elementary school (n = 7), and co-payment continuing beyond elementary school (n = 17). The effects of six interaction terms, each representing a unique pairing from the four independent variables, were individually calculated. RESULTS S-FMR was negatively associated with the SCR of deciduous tooth extractions and DMFT (coefficient = -0.11, 95% CI -0.20; -0.01 and coefficient = -0.003, 95% CI -0.005; -0.001, respectively). No co-payment until children enter elementary school was positively associated with the SCR of deciduous tooth extraction compared to co-payment until children enter elementary school(coefficient = 11.42, 95% CI 3.29; 19.55). SCR of dental sealants was positively associated with the SCR of deciduous tooth extractions (coefficient = 0.12, 95% CI 0.06; 0.19) but negatively associated with DMFT (coefficient = -0.001, 95% CI -0.003; -0.0001). Per capita prefectural income was positively associated with the SCR of deciduous tooth extractions(coefficient = 0.01, 95% CI 0.001; 0.02). No interaction was found between S-FMR and the subsidy policy at both outcomes. CONCLUSION High S-FMR utilization and no co-payment until children enter elementary school were associated with fewer deciduous tooth extractions. Also, S-FMR and dental sealant were associated with decreased DMFT.

Associations of ADH1B and ALDH2 genotypes and alcohol flushing with drinking history, withdrawal symptoms, and ICD-10 criteria in Japanese alcohol-dependent men. Pharmacogenet Genomics 2024:01213011-990000000-00054.

Abstract
OBJECTIVES Given the high prevalence of fast-metabolizing alcohol dehydrogenase-1B*2 (ADH1B*2) and inactive aldehyde dehydrogenase-2*2 (ALDH2*2) alleles in East Asians, we evaluated how the ADH1B/ALDH2 genotypes and alcohol flushing might affect the development of alcohol dependence (AD). METHODS We evaluated how the ADH1B/ALDH2 genotypes and self-reported alcohol flushing affected history of drinking events and withdrawal symptoms and ICD-10 criteria in 4116 Japanese AD men. RESULTS The ADH1B*1/*1 group and ALDH2*1/*1 group were 1-5 years younger than the ADH1B*2(+) and ALDH2*1/*2 groups, respectively, for all of the ages at onset of habitual drinking, blackouts, daytime drinking, uncontrolled drinking, withdrawal symptoms, and first treatment for AD, and the current age. Blackouts were more common in the ADH1B*1/*1 group and ALDH2*1/*1 group. Daytime drinking, uncontrolled drinking, and withdrawal symptoms, such as hand tremor, sweating, convulsions, and delirium tremens/hallucinations were more common in the ADH1B*1/*1 group. The ADH1B*1/*1 was positively associated with the ICD-10 criteria for 'tolerance' and 'withdrawal symptoms'. The ADH1B*1/*1 group and ALDH2*1/*2 group had a larger ICD-10 score. Never flushing was reported by 91.7% and 35.2% of the ALDH2*1/*1 and ALDH2*1/*2 carriers, respectively. After a 1-2-year delay in the onset of habitual drinking in the former-/current-flushing group, no differences in the ages of the aforementioned drinking milestones were found according to the flushing status. CONCLUSION The ADH1B*1/*1 and ALDH2*1/*1 accelerated the development of drinking events and withdrawal symptoms in Japanese AD patients. ICD-10 score was larger in the ADH1B*1/*1 group and ALDH2*1/*2 group. The effects of alcohol flushing on drinking events were limited.

Coffee and caffeine intake reduces risk of ulcerative colitis: a case-control study in Japan. J Gastroenterol Hepatol 2024; 39:512-518. [PMID: 38073066 DOI: 10.1111/jgh.16439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 09/14/2023] [Accepted: 11/14/2023] [Indexed: 03/05/2024]
Abstract
BACKGROUND AND AIM Although diet is one of the potential environmental factors affecting ulcerative colitis (UC), evidence is not sufficient to draw definitive conclusions. This Japanese case-control study examined the association between the consumption of coffee, other caffeine-containing beverages and food, and total caffeine and the risk of UC. METHODS The study involved 384 UC cases and 665 control subjects. Intake of coffee, decaffeinated coffee, black tea, green tea, oolong tea, carbonated soft drinks, and chocolate snacks was measured with a semiquantitative food-frequency questionnaire. Adjustments were made for sex, age, pack-years of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, body mass index, and intake of vitamin C, retinol, and total energy. RESULTS Higher consumption of coffee and carbonated soft drinks was associated with a reduced risk of UC with a significant dose-response relationship (P for trend for coffee and carbonated soft drinks were <0.0001 and 0.01, respectively), whereas higher consumption of chocolate snacks was significantly associated with an increased risk of UC. No association was observed between consumption of decaffeinated coffee, black tea, green tea, or oolong tea and the risk of UC. Total caffeine intake was inversely associated with the risk of UC; the adjusted odds ratio between extreme quartiles was 0.44 (95% confidence interval: 0.29-0.67; P for trend <0.0001). CONCLUSIONS We confirmed that intake of coffee and caffeine is also associated with a reduced risk of UC in Japan where people consume relatively low quantities of coffee compared with Western countries.

Time Trends in Income-related Differences in Food Group Intakes: The National Health and Nutrition Survey, Japan in 2010, 2014, and 2018. J Epidemiol 2024; 34:76-86. [PMID: 36908117 PMCID: PMC10751188 DOI: 10.2188/jea.je20220220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Accepted: 02/05/2023] [Indexed: 03/13/2023] Open
Abstract
BACKGROUND We aimed to clarify whether differences in food group intake according to household income have changed over the last decade in Japanese people aged 20 years or older. METHODS This cross-sectional study was based on the 2010, 2014, and 2018 National Health and Nutrition Surveys in Japan. Food intake was assessed using a 1-day semi-weighed household dietary record. The participants were categorized into three groups based on their income. The mean of each food intake according to the income group was estimated by adjusting for age, occupation, and number of participants from the same household. The significance of the interaction terms between income and survey year was evaluated to assess the change in income-related differences in food intake over time. RESULTS Cereal intake was lower in the middle- and the highest-income groups than in the lowest-income group, regardless of sex, and the interaction between income and year was nonsignificant for cereal intake. In the former two surveys, vegetable intake was higher among the highest-income women, while in the 2018 survey, the vegetable intake decreased in the women in the middle- and the highest-income groups. The interaction between income and year was significant for vegetable intake among the women. For other foods, the differences in intake among the income groups did not significantly change over time. CONCLUSION The tendency for lower cereal intake in the higher-income groups was consistent over time in both the sexes, and the tendency for higher vegetable intake in the highest income women disappeared over time.

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Association between continuous cessation or reduction of drinking alcohol and improvement of multiple dysplastic lesions in patients with esophageal squamous cell carcinoma after endoscopic resection. Esophagus 2024; 21:31-40. [PMID: 38070099 DOI: 10.1007/s10388-023-01033-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Accepted: 11/03/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND Multiple development of squamous cell carcinoma (SCC) in the upper aerodigestive tract has been explained by the 'field cancerization phenomenon' associated with alcohol drinking. Squamous dysplastic lesion is clinically visualised as a Lugol-voiding lesion (LVL) by chromoendoscopy. Whether cessation or reduction of alcohol drinking improves multiple LVL and reduces the risk of field cancerization has not been elucidated. METHODS We analysed 330 patients with newly diagnosed superficial esophageal SCC (ESCC) enrolled in the cohort study. The grade of LVL was assessed in all patients every 6 months. We instructed the patients to stop smoking and drinking and recorded their drinking and smoking status every 6 months. RESULTS Among 330 patients, we excluded 98 with no LVL or no drinking habit. Of the remaining 232 patients, 158 continuously ceased or reduced their drinking habit. Patients who ceased or reduced their drinking habit significantly showed improvement in the grade of LVL. Multivariate analysis showed that continuous cessation or reduction of drinking habit improved the grade of LVL (hazard ratio [HR] = 8.5, 95% confidence interval [CI] 1.7-153.8, p = 0.0053). Higher grade of LVL carried a high risk of multiple ESCC and head and neck SCC (HNSCC) (HR = 3.7, 95% CI 2.2-6.4, p < 0.0001). Improvement in LVL significantly decreased the risk of multiple ESCC and HNSCC (HR = 0.2, 95% CI 0.04-0.7, p = 0.009). CONCLUSIONS This is the first report indicating that field cancerization was reversible and cessation or reduction of drinking alcohol could prevent multiple squamous dysplastic lesion and multiple ESCC and HNSCC development.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Metachronous primary gastric cancer after endoscopic resection in patients with esophageal squamous cell carcinoma. Gastric Cancer 2023; 26:988-1001. [PMID: 37368170 DOI: 10.1007/s10120-023-01413-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 06/14/2023] [Indexed: 06/28/2023]
Abstract
BACKGROUND This study aimed to evaluate the risk factors for developing metachronous primary Gastric Cancer (GC) after Endoscopic Resection (ER) for esophageal Squamous Cell Carcinoma (SCC). METHODS We studied 283 patients with esophageal SCC who underwent ER. The study outcomes were as follows: (1) incidence of metachronous primary GC after ER; and (2) predictors for the development of metachronous primary GC after ER by the Cox proportional hazards model. RESULTS The median follow-up was 43.1 months (1.81-79.1), and the 3-year cumulative incidence of metachronous primary GC was 6.5% (95%CI: 4.1-10.4). The incidence of metachronous primary GC during the follow-up period was 2.31 per 100 person-years. The frequencies of severe gastric atrophy and macrocytosis at the timing of ER were significantly higher in patients with than without metachronous primary GC (91.7% vs. 73.2%, p = 0.0422, 20.8% vs. 5.2%, p = 0.0046, respectively). Severe gastric atrophy was associated with the development of metachronous primary GC (sex-and-age adjusted hazard ratio (HR) [95%CI] = 4.12 [0.95-27.78], p = 0.0093). Macrocytosis was associated with the development of metachronous primary GC (sex-and-age adjusted HR = 4.76 [1.75-13.0], p = 0.0012) and found to be an independent predictor for metachronous primary GC by multivariate Cox proportional hazards analysis (HR [95%CI] = 4.35 [1.60-11.84], p = 0.004). CONCLUSIONS Severe gastric atrophy and macrocytosis should be noted in the development of metachronous primary GC after ER for esophageal SCC. In particular, macrocytosis at the timing of ER was considered an important predictor. CLINICAL TRIALS REGISTRY NUMBER UMIN000001676.

Assessment of skeletal muscle using deep learning on low-dose CT images. Glob Health Med 2023; 5:278-284. [PMID: 37908512 PMCID: PMC10615034 DOI: 10.35772/ghm.2023.01050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 09/08/2023] [Accepted: 09/22/2023] [Indexed: 11/02/2023]
Abstract
The visceral fat area obtained by computed tomography (CT) at the navel level is clinically used as an indicator of visceral fat obesity in Japan. Analysis of skeletal muscle mass using CT images at the navel level may potentially support concurrent assessment of sarcopenia and sarcopenic obesity. The purpose of this study was to assess the performance of deep learning models (DLMs) for skeletal muscle mass measurement using low-dose abdominal CT. The primary dataset used in this study included 11,494 low-dose abdominal CT images at navel level acquired in 7,370 subjects for metabolic syndrome screening. The publicly available Cancer Imaging Archive (TCIA) dataset, including 5,801 abdominal CT images, was used as a complementary dataset. For abdominal CT image segmentation, we used the SegU-net DLM with different filter size and hierarchical depth. The segmentation accuracy was assessed by measuring the dice similarity coefficient (DSC), cross-sectional area (CSA) error, and Bland-Altman plots. The proposed DLM achieved a DSC of 0.992 ± 0.012, a CSA error of 0.41 ± 1.89%, and a Bland-Altman percent difference of -0.1 ± 3.8%. The proposed DLM was able to automatically segment skeletal muscle mass measurements from low-dose abdominal CT with high accuracy.

Effect of a Community-Based Program to Accelerate Referral to Physicians for Individuals at High-Risk of Lifestyle-Related Diseases: A Cluster Randomized Trial. J Atheroscler Thromb 2023; 30:1389-1406. [PMID: 36878606 PMCID: PMC10564631 DOI: 10.5551/jat.64100] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 01/23/2023] [Indexed: 03/08/2023] Open
Abstract
AIM A cluster randomized trial was conducted within 43 Japanese municipalities (21 intervention and 22 usual care) to examine whether the standardized health counseling for individuals at high cardiovascular risk screened at community sites accelerates clinic visits to strengthen the primary health care system. METHODS Among high-risk individuals aged 40-74 years screened by health checkups, 8,977 and 6,733 were allocated to the intervention and usual care groups, respectively, who were not under medical treatment but had high levels of blood pressure (systolic/diastolic ≥ 160/100 mmHg), hemoglobin A1c or glucose (≥ 7.0% or corresponding glucose levels), LDL-cholesterol (≥ 180 mg/dL for men), and/or proteinuria of ≥ 2+. The intervention was performed from May 2014 to March 2016 under a standardized health counseling program based on the health belief model primarily by public health nurses. The usual care group was provided with local counseling protocols. RESULTS The cumulative proportions of clinic visits for 12 months after health checkups were 58.1% (95% confidence interval, 57.0%, 59.3%) versus 44.5% (43.2%, 45.8%), with the probability ratio of clinic visits between the groups being 1.46 (1.24, 1.72). The between-group differences between the baseline and 1-year surveys were -1.50 (-2.59, -0.41) mmHg for diastolic blood pressure in the hypertension category, -0.30% (-0.53%, -0.07%) for HbA1c in the diabetes category, -0.37 (-0.48, -0.27) mmol/L for LDL-cholesterol in the dyslipidemia category, and none for proteinuria. CONCLUSION Standardized health counseling for high-risk individuals accelerated clinic visits, with larger reductions in blood pressure, HbA1c, and LDL-cholesterol levels. The nationwide use of counseling after health checkups for high-risk individuals could help in controlling risk factors and in preventing lifestyle-related diseases.

Gap between the concerns of healthcare professionals and parents' perceptions regarding dietary habits for 18-month- and 3-year-old children in Japan. BMC Public Health 2023; 23:1891. [PMID: 37777710 PMCID: PMC10544123 DOI: 10.1186/s12889-023-16743-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 09/12/2023] [Indexed: 10/02/2023] Open
Abstract
BACKGROUND A gap has been reported between healthcare professionals' (hereafter "professionals") recognition of preschool children's diets and parents' perception of concern. This study investigated the gap between the concerns reported by professionals and parents' perceptions regarding health and dietary habits by age (18 months and 3 years) and gender in Japan. METHODS The study design consisted of a cross-sectional, multilevel survey. The request letters were sent to all households with target children with the cooperation of local governments. After obtaining written informed consent from parents, questionnaires were distributed to them. The survey included 30 items on children's concerns about health and dietary habits. At the health checkup, parents indicated whether they were concerned in response to each item, and responded child's height and weight and birth height and weight. Next, the professionals provided counseling to the parents at a health checkup. After that, the professionals noted their concerns in response to the same 30 items as those given to parents. The participation rates were 82.9% (18 months) and 82.8% (3 years). Data of 239 persons for 18 months and 223 persons for 3 years old were analyzed. In the statistical analysis, the items that were judged as concerning by professionals but not by parents were identified; likewise, the items that were of concern to parents but not to professionals were identified. Sensitivity, false negative rate, specificity, false positive rate, and Youden index were calculated to analyze the discordance rate for each item. RESULTS Many parents in this study were concerned about the issues that professionals did not consider to be concerning. Moreover, the parents worried about more issues for 3-year-olds than for 18-month-olds. The items for which ≥ 10 professionals indicated concerns and with higher discordance between the professionals and parents for both boys and girls were "picky eating" for 18-month-olds and "inconsistent amount of food" for 3-year-olds. CONCLUSIONS The concerns that professionals have with respect to children's diets and the things that parents worry about show gaps. It might be necessary to provide professional counseling for parents to develop a correct understanding of their children's dietary habits.

Risk factors for the development of second primary esophageal squamous-cell carcinoma after endoscopic resection for esophageal squamous-cell carcinoma according to genetic polymorphisms related to alcohol and nicotine metabolism. Jpn J Clin Oncol 2023; 53:774-780. [PMID: 37370215 DOI: 10.1093/jjco/hyad070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 06/13/2023] [Indexed: 06/29/2023] Open
Abstract
BACKGROUND Multiple development of esophageal squamous-cell carcinoma is explained by field cancerization and is associated with alcohol consumption and smoking. We investigated the association between the development of second primary esophageal squamous-cell carcinoma after endoscopic resection for esophageal squamous-cell carcinoma and genetic polymorphisms related to alcohol and nicotine metabolism. METHODS The study group comprised 56 patients with esophageal squamous-cell carcinoma after endoscopic resection. The main variables were the following: (i) cumulative incidence and total number of second primary esophageal squamous-cell carcinoma according to genetic polymorphisms in alcohol dehydrogenase 1B, aldehyde dehydrogenase 2 and cytochrome P450 2A6; and (ii) risk factors of second primary esophageal squamous-cell carcinoma identified using a multivariate Cox proportional-hazards model. The frequencies of alcohol dehydrogenase 1B, aldehyde dehydrogenase 2 and cytochrome P450 2A6 genetic polymorphisms in the buccal mucosa were analyzed. RESULTS The median follow-up was 92.8 months (range: 2.7-134.2). Slow-metabolizing alcohol dehydrogenase 1B was associated with a higher 7-year cumulative incidence of second primary esophageal squamous-cell carcinoma (fast-metabolizing alcohol dehydrogenase 1B vs slow-metabolizing alcohol dehydrogenase 1B: 20.5% vs 71.4%, P = 0.006). Slow-metabolizing alcohol dehydrogenase 1B (relative risk [95% confidence interval]: 3.17 [1.49-6.73]), inactive aldehyde dehydrogenase 2 (2.17 [1.01-4.63]) and poorly-metabolizing cytochrome P450 2A6 (4.63 [1.74-12.33]) had a significantly higher total number of second primary esophageal squamous-cell carcinoma per 100 person-years. In the multivariate Cox proportional-hazards model, slow-metabolizing alcohol dehydrogenase 1B was a significant risk factor of the development of second primary esophageal squamous-cell carcinoma (hazard ratio 9.92, 95% confidence interval: 2.35-41.98, P = 0.0018). CONCLUSIONS Slow-metabolizing alcohol dehydrogenase 1B may be a significant risk factor for the development of second primary esophageal squamous-cell carcinoma. In addition, inactive aldehyde dehydrogenase 2 and poorly-metabolizing cytochrome P450 2A6 may be important factors.

Curative Management After Endoscopic Resection for Esophageal Squamous Cell Carcinoma Invading Muscularis Mucosa or Shallow Submucosal Layer-Multicenter Real-World Survey in Japan. Am J Gastroenterol 2023; 118:1175-1183. [PMID: 36624037 DOI: 10.14309/ajg.0000000000002106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 11/03/2022] [Indexed: 01/11/2023]
Abstract
INTRODUCTION Curative management after endoscopic resection (ER) for esophageal squamous cell carcinoma (ESCC), which invades the muscularis mucosa (pMM-ESCC) or shallow submucosal layer (pSM1-ESCC), has been controversial. METHODS We identified patients with pMM-ESCC and pSM1-ESCC treated by ER. Outcomes were the predictive factors for regional lymph node and distant recurrence, and survival data were based on the depth of invasion, lymphovascular invasion (LVI), and additional treatment immediately after ER. RESULTS A total of 992 patients with pMM-ESCC (n = 749) and pSM1-ESCC (n = 243) were registered. According to the multivariate Cox proportional hazards analysis, pSM1-ESCC (hazard ratio = 1.88, 95% confidence interval 1.15-3.07, P = 0.012) and LVI (hazard ratio = 6.92, 95% confidence interval 4.09-11.7, P < 0.0001) were associated with a risk of regional lymph node and distant recurrence. In the median follow-up period of 58.6 months (range 1-233), among patients with risk factors (pMM-ESCC with LVI or pSM1-ESCC), the 5-year overall survival rates, relapse-free survival rates, and cause-specific survival rates of patients with additional treatment were significantly better than those of patients without additional treatment; 85.4% vs 61.5% ( P < 0.0001), 80.5% vs 53.3% ( P < 0.0001), and 98.5% vs 93.1% ( P = 0.004), respectively. There was no difference in survival rate between the chemoradiotherapy and surgery groups. DISCUSSION pSM1 and LVI were risk factors for metastasis after ER for ESCC. To improve the survival, additional treatment immediately after ER, such as chemoradiotherapy or surgery, is effective in patients with these risk factors.

Validation of Dietary Intake Estimated by Web-Based Dietary Assessment Methods and Usability Using Dietary Records or 24-h Dietary Recalls: A Scoping Review. Nutrients 2023; 15:nu15081816. [PMID: 37111035 PMCID: PMC10141001 DOI: 10.3390/nu15081816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 03/29/2023] [Accepted: 04/05/2023] [Indexed: 04/29/2023] Open
Abstract
The goal was to summarize studies comparing the accuracy of web-based dietary assessments with those of conventional face-to-face or paper-based assessments using 24-h dietary recall or dietary record methods in the general population. Using two databases, mean differences and correlation coefficients (CCs) for intakes of energy, macronutrients, sodium, vegetables, and fruits were extracted from each study independently by the authors. We also collected information regarding usability from articles reporting this. From 17 articles included in this review, the mean dietary intake differences in the web-based dietary assessment compared to conventional methods, were -11.5-16.1% for energy, -12.1-14.9% for protein, -16.7-17.6% for fat, -10.8-8.0% for carbohydrates, -11.2-9.6% for sodium, -27.4-3.9% for vegetables, and -5.1-47.6% for fruits. The CC was 0.17-0.88 for energy, protein, fat, carbohydrates, and sodium, and 0.23-0.85 for vegetables and fruits. In three out of four studies reporting usability, more than half of the participants preferred the web-based dietary assessment. In conclusion, % difference and CC of dietary intake were acceptable in both web-based dietary records and 24-h dietary recalls. The findings from this review highlight the possibility of wide-spread application of the web-based dietary assessment in the future.

We Should Pay More Attention to Sex Differences to Predict the Risk of Severe COVID-19: Men Have the Same Risk of Worse Prognosis as Women More Than 10 Years Older. J Epidemiol 2023; 33:38-44. [PMID: 35851563 PMCID: PMC9727213 DOI: 10.2188/jea.je20220056] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Prioritization for novel coronavirus disease 2019 (COVID-19)-related health policies usually considers age and certain other characteristics, but sex is rarely included, despite the higher risk of severe disease in men. The aim of this study was to compare the impact of sex and age on the severity of COVID-19 by estimating the age difference in years for which the risk for men versus women is the same. METHODS We analyzed 23,414 Japanese COVID-19 inpatients aged 20-89 years (13,360 men and 10,054 women). We graded the severity of COVID-19 (0 to 5) according to the most intensive treatment required during hospitalization. The risk of grade 2/3/4/5 (non-invasive positive pressure ventilation/invasive mechanical ventilation/extracorporeal membrane oxygenation/death), grade 3/4/5, and separately grade 5 was analyzed using a multiple logistic regression model. RESULTS The odds ratio (OR) of grades 2/3/4/5, 3/4/5 (primary outcome), and 5 for men relative to women was 2.76 (95% CI, 2.44-3.12), 2.78 (95% CI, 2.42-3.19), and 2.60 (95% CI, 2.23-3.03), respectively, after adjustment for age and date of admission. These risks for men were equivalent to those for women 14.1 (95% CI, 12.3-15.8), 11.2 (95% CI, 9.7-12.8), and 7.5 (95% CI, 6.3-8.7) years older, respectively. CONCLUSION The risks of worse COVID-19 prognosis (grades 3/4/5) in men were equivalent to those of women 11.2 years older. Reanalyzing data extracted from four previous studies also revealed a large impact of sex difference on the severity of COVID-19. We should pay more attention to sex differences to predict the risk of COVID-19 severity and to formulate public health policy accordingly.

Nonsmoking after simultaneous alcohol abstinence and smoking cessation program was associated with better drinking status outcome in Japanese alcohol-dependent men: A prospective follow-up study. PLoS One 2023; 18:e0282992. [PMID: 36989266 PMCID: PMC10057780 DOI: 10.1371/journal.pone.0282992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 03/01/2023] [Indexed: 03/30/2023] Open
Abstract
BACKGROUND Growing evidence suggests that intervention for smoking cessation enhances alcohol abstinence in treatment settings for alcohol dependence. However, research in this field is rare in Asians. METHOD We prospectively investigated the association of smoking status with drinking status using 9 surveys mailed during a 12-month period in 198 Japanese alcohol-dependent men (70 never/ex-smokers and 128 smokers) who admitted for the first time and completed a 3-month inpatient program for simultaneous alcohol abstinence and smoking cessation. RESULTS Nonsmoking during the first month after discharge and at the end of follow-up was reported in 28.9% and 25.0% of the baseline smokers, respectively. Kaplan-Meier estimates showed that a 12-month alcohol abstinence and heavy-drinking-free status were more frequent among never/ex-smokers (45.1% and 59.8%, respectively) and baseline smokers who quit smoking during the first month after discharge (59.0% and 60.8%, respectively), compared with sustained smokers (30.0% and 41.2%, respectively). Among the baseline smokers, the multivariate odds ratio (95% confidence interval) for smoking cessation during the first month were 2.77 (1.01-7.61) for alcohol abstinence during the period and 2.50 (1.00-6.25) for use of varenicline, a smoking cessation agent, during the inpatient program. After adjusting for age, drinking profile, lifestyle, family history of heavy or problem drinking, lifetime episodes of other major psychiatric disorders, and medications at discharge, the multivariate hazard ratios (HRs) for drinking lapse were 0.57 (0.37-0.89) for the never/ex-smoking and 0.41 (0.23-0.75) for new smoking cessation groups, respectively, compared with sustained smoking, while the corresponding HRs for heavy-drinking lapse were 0.55 (0.33-0.90) and 0.47 (0.25-0.88), respectively. The HR for drinking lapse was 0.63 (0.42-0.95) for the nonsmoking group (vs. smoking) during the observation period, while the HR for heavy-drinking lapse was 0.58 (0.37-0.91) for the nonsmoking group (vs. smoking) during the observation period. Other significant variables that worsened drinking outcomes were higher daily alcohol intake prior to hospitalization, family history of heavy or problem drinking and psychiatric medications at discharge. CONCLUSION Nonsmoking was associated with better outcomes on the drinking status of Japanese alcohol-dependent men, and a smoking cessation program may be recommended to be integrated into alcohol abstinence programs.

Abstract
Aging is an essential milestone that governments worldwide must plan for. At a global level, Japan currently has the highest share of population older than 65 years. Thus, the Japanese experience may be a useful guide to other countries as they consider their policies. Elderly individuals living alone encounter many challenges typically not faced by those living in a multiperson household. Nutrition status and diet are 2 such challenges, both of which are crucial determinants of health and well-being. The health and nutrition statuses as well as some other factors in elderly individuals living alone in Japan were investigated. The identification of the factors relating to food diversity, social relationships, and physical ability, among others, indicates, as hypothesized, that the relationship between individual and environmental factors is associated with the health, nutritional statuses, and diets of elderly people living alone. The findings and approach may be useful to scholars and policy makers in significantly aging societies like Japan as well as other societies experiencing population aging.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) is an established minimally invasive treatment for elderly patients with severe aortic stenosis (AS). Although it is a relatively minimally invasive procedure, many elderly patients cannot undergo TAVI due to advanced age, advanced dementia, significantly impaired ADL, or because the patient or family does not wish to undergo TAVI. In general, severe AS patients died 5 years after an angina attack, 3 years after syncope symptoms, and 2 years after heart failure symptoms. However, few studies have investigated the prognosis of elderly patients with severe AS who declined TAVI.
Purpose
This study aimed to comprehend the natural history of elderly severe AS patients who declined aortic valve intervention and identify risk factors for death in the TAVI era.
Methods
We retrospectively reviewed 2,786 echocardiographic data from our hospital between 2017 and 2021. We identified 504 patients with AS in the echocardiography database. The severe AS was defined by the following echocardiography parameters: peak aortic flow velocity ≥4.0 m/s, aortic valve mean gradient ≥40 mmHg, aortic valve area (AVA)<1.0 cm2, or AVA index<0.6 cm2/m2. Patients with mild and moderate AS and patients who underwent surgical or transcatheter aortic valve intervention were excluded. Eventually, 82 patients fulfilled the study criteria and were analyzed in this study. Clinical events were investigated, and Cox proportional hazards analysis was performed to elucidate risk factors for mortality.
Results
The mean age was 89±6 years, and 63 (77%) were women. AHA/ACC classification was Stage A/B/C/D: 0%/52.4%/39.0%/8.5%. As event occurrence, we detected 34 (41.5%) all-cause deaths, 41 (50.0%) major adverse cardiovascular events, 32 (39.0%) development of heart failure, 13 (15.9%) chest pain attacks, and 3 (3.7%) syncope. The time from diagnosis of severe AS to all-cause death was 227±273 days, and the 1-, 2-, and 3-year survival rates were 61.5%, 46.2%, and 36.9%, respectively. Of the heart failure-onset population, 16 (50.0%) were found to have severe AS on initial heart failure admission. The incidence of heart failure at 1, 2, and 3 years after diagnosis of severe AS was 60.1%, 56.7%, and 45.4%, respectively. The time from heart failure to death was 107±147 days. Cox proportional hazards analysis adjusted with age, sex, comorbidities revealed that dementia (HR 4.5, P=0.014) and Katz index <5 (HR7.8, P=0.009) were independent risk factors for mortality.
Conclusions
Compared to the comprehension of the natural history of AS patients, the prognosis in severe AS patients who declined TAVI was extremely poor. Although the elderly patients did not have a high rate of angina attacks or syncope symptoms, probably due to their reduced ADL, the results suggest that dementia prevention and maintenance of exercise tolerance are essential since dementia and reduced ADL (Katz<5) are independent risk factors for mortality.

Abstract
OBJECTIVES To determine national medium-term trends in dental visits during three COVID-19 emergency declaration periods in Japan and to analyse how these trends varied according to prefectural emergency measures and COVID-19 incidence. DESIGN AND SETTING A retrospective observational study of Japan's dental claims from January 2017 to December 2021. DATA SOURCES Data from a monthly report by the Health Insurance Claims Review and Reimbursement Services (HICRRS) in Japan. HICRRS handles the claims of employer-based health insurance. DATA ANALYSIS We determined the number of monthly dental claims nationwide from January 2017 to December 2021 and the percentage change in the number of monthly dental claims based on the difference in the COVID-19 alert level between the three emergency declaration periods in 2020-2021 and the corresponding periods in 2019. Results were analysed using descriptive statistics, multiple regression model, graphical figures, and narrative synthesis. OUTCOME MEASURES The main outcome was the change in the number of dental visits between the emergency declaration periods in 2020-2021 and the corresponding periods in 2019. We also assessed the difference in the number of dental visits based on the COVID-19 alert level. RESULTS The data set included a total of 736 946 088 dental claims. Until the end of 2021, the greatest decrease in monthly dental claims was in April 2020, which was 22.3% lower than that in April 2019. As indicated by the coefficient in the regression model, the percentage change in monthly dental claims decreased by 5.01% (95% CI -8.27 to -1.74) depending on the difference between the prefectures designated as being under special precautions and other prefectures. CONCLUSIONS The decrease in dental visits was greater during the first state of emergency, ie, April-May 2020, and in prefectures designated as being under special precautions. Further efforts to promote appropriate dental visits at different alert levels are necessary.

IL12B rs6887695 polymorphism and interaction with alcohol intake in the risk of ulcerative colitis in Japan. Cytokine 2022; 155:155901. [PMID: 35567898 DOI: 10.1016/j.cyto.2022.155901] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 04/08/2022] [Accepted: 04/29/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND The interleukin (IL)-23/Th17 pathway plays a critical role in ulcerative colitis (UC). The IL-12p40 subunit, which is shared by IL-23 and IL-12, is encoded by the IL12B gene. The current case-control study investigated the association between IL12B SNP rs6887695 and the UC risk. METHODS There were 384 cases within 4 years of UC diagnosis and 661 controls who were enrolled. Adjustments were made for sex, age, pack-years of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, and body mass index. RESULTS Subjects with the GG IL12B SNP rs6887695 genotype had a significantly increased risk of UC compared with those with the CC genotype (adjusted odds ratio [AOR], 1.60; 95% confidence interval [CI], 1.08-2.36). This positive association was also significant using the additive and recessive models (AOR, 1.25; 95% CI, 1.03-1.52; AOR, 1.50; 95% CI, 1.08-2.09, respectively). An independent inverse relationship was observed between ever alcohol consumption and the UC risk in those with the CC genotype while no significant association was found in those with at least one G allele (P for interaction = 0.0008). CONCLUSIONS IL12B SNP rs6887695 was significantly associated with UC. The influence of alcohol consumption might rely on rs6887695.

Active and passive smoking and risk of ulcerative colitis: A case-control study in Japan. J Gastroenterol Hepatol 2022; 37:653-659. [PMID: 34845747 DOI: 10.1111/jgh.15745] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 10/28/2021] [Accepted: 11/16/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND AND AIM Although an inverse relationship between current smoking and the development of ulcerative colitis (UC) has been shown in North America and Europe, evidence is limited in Asian countries, where the incidence of UC is rapidly increasing. This Japanese case-control study examined the association between active and passive smoking and risk of UC. METHODS A self-administered questionnaire was used to obtain information on smoking and potential confounding factors in 384 cases with a diagnosis of UC within the past 4 years and 665 controls. RESULTS Compared with having never smoked, having ever smoked was associated with an increased risk of UC (adjusted odds ratio [OR] = 1.70, 95% confidence interval [CI]: 1.23-2.37). No association was observed between current smoking and risk of UC, but former smokers had a significant elevation in risk (adjusted OR = 2.40, 95% CI: 1.67-3.45). There was a positive dose-response relationship with pack-years smoked (P for trend = 0.006). Among never smokers, passive smoking exposure at home was significantly associated with an increased risk of UC (adjusted OR = 1.90, 95% CI: 1.30-2.79). A significant dose-response gradient was also observed between pack-years of passive smoking at home and risk of UC (P for trend = 0.0003). CONCLUSIONS We confirmed that former smoking elevated the risk of UC, whereas an inverse association between current smoking and the risk of UC did not reach a statistically significant level. Passive smoking may be associated with an increased risk of UC.

Abstract
Objectives In response to the spread of SARS-CoV-2, a state of emergency was declared in Japan on April 7, 2020, and in the same month, Japan's Ministry of Health, Labor, and Welfare informed dentists of the need to postpone non-emergency dental care. The purpose of this study was to identify the patients who refrained from dental care during the state of emergency in April 2020, and to clarify their personal characteristics.Methods A total of 1,335 patients who visited 28 dental clinics in Saitama in September 2020 completed survey questionnaires; of these, 1,227 valid responses were received. Among those who sought dental care under the state of emergency, those who did not visit a dental clinic comprised the "refrained group" and those who visited the dental clinics comprised the "visited group".Results Multivariate logistic regression analysis showed that the odds ratios for the "refrained group" were 1.69 (95%Cl: 1.12-2.55) for females, 2.91 (95%Cl: 1.88-4.49) for those younger than 65 years, 1.71 (95%Cl: 1.04-2.82) for those that visited the dental clinic less than once a month, and 7.12 (95%Cl: 4.56-11.11) for those who did not have an appointment during the state of emergency.Conclusion In conclusion, 35% of patients in this study refrained from visiting the dental clinic during the state of emergency. The related factors for refraining from dental care were being females, middle-aged (<65 years), visiting the dental clinic less than once a month, and not having an appointment during the COVID-19 state of emergency.

Smoking and severe illness in hospitalized COVID-19 patients in Japan. Int J Epidemiol 2021; 51:1078-1087. [PMID: 34894230 PMCID: PMC8689860 DOI: 10.1093/ije/dyab254] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 11/19/2021] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND The aim of this study was to identify associations between smoking status and the severity of COVID-19, using a large-scale data registry of hospitalized COVID-19 patients in Japan (COVIREGI-JP), and to explore the reasons for the inconsistent results previously reported on this subject. METHODS The analysis included 17 666 COVID-19 inpatients aged 20-89 years (10 250 men and 7416 women). We graded the severity of COVID-19 (grades 0 to 5) according to the most intensive treatment required during hospitalization. The smoking status of severe grades 3/4/5 (invasive mechanical ventilation/extracorporeal membrane oxygenation/death) and separately of grade 5 (death) were compared with that of grade 0 (no oxygen, reference group) using multiple logistic regression. Results were expressed as odds ratios (OR) and 95% confidence intervals (CI) adjusted for age and other factors considering the potential intermediate effects of comorbidities. RESULTS Among men, former smoking significantly increased the risk of grade 3/4/5 and grade 5, using grade 0 as a reference group, with age- and admission-date-adjusted ORs (95% CI) of 1.51 (1.18-1.93) and 1.65 (1.22-2.24), respectively. An additional adjustment for comorbidities weakened the ORs. Similar results were seen for women. Current smoking did not significantly increase the risk of grade 3/4/5 and grade 5 in either sex. CONCLUSIONS The severity of COVID-19 was not associated with current or former smoking per se but with the comorbidities caused by smoking. Thus, smoking cessation is likely to be a key factor for preventing smoking-related disease and hence for reducing the risk of severe COVID-19.

Abstract
Abstract
Background
Vascular endothelial growth factor (VEGF) family is overexpressed in the tumor microenvironment and induces tumor angiogenesis.1 VEGF signaling pathway (VSP) inhibitors are essential therapeutic drugs for solid cancer patients.2 However, VSP inhibitors often provoke drug-specific anti-angiogenesis in normal tissues, which was referred to as on-target toxicity.2 Hypertension (HTN) is one of the most frequent adverse events caused by VSP inhibitors. A previous report demonstrated that VSP inhibitor-induced hypertension is a favorable prognostic factor, contrarily.3However, multiple VSP inhibitors are administered in various cancer types, and then the relation between VSP inhibitor-associated hypertension and clinical outcome is still controversial.
Purpose
The aim of this study is to elucidate the impacts of HTN and the timing of onset on clinical outcome during cancer therapy with VSP inhibitors.
Method
We reviewed 2,348 patients who were treated with VSP inhibitors from the LIFE Study database, consisting of 14 municipality-level information from claims data between 2016 and 2020. According to the timing of HTN onset mode, the patients were stratified into 3 groups; (1) new-onset HTN group (n=334): de novo development after VSP inhibitor administration, (2) pre-existing HTN group (n=1,363): existing HTN at baseline, including aggravation after VSP inhibitor initiation, and (3) no HTN group (n=651) (Figure 1). The time to treatment failure (TTF) was applied as a surrogate clinical indicator of overall survival. Event-free survival analysis with the log-rank test was conducted for time to first treatment failure amongst the 3 groups. In addition, Cox proportional hazard models adjusted with clinical characteristics were performed to investigate independent factors for TTF.
Results
In the event-free survival analysis, both the new-onset HTN and the pre-existing HTN were associated with prolongation of TTF, compared to the non-HTN (p<0.001 and p<0.001, respectively, by Bonferroni correction) (Figure 2). The New-onset HTN was significantly associated with longer TTF than pre-existing HTN (p<0.001). In Cox proportional hazard model adjusted with age, sex, past medical history, primary cancer lesion, and type of VSP inhibitors, the new-onset HTN and the pre-existing HTN were independent favorable factors, compared to the non-HTN [new-onset HTN: Hazard ratio (HR) 0.62, 95% confidence interval (CI) 0.54 - 0.71, p<0.001; and pre-existing HTN: HR 0.85, 95% CI 0.77 - 0.94, p<0.005]. Moreover, the New-onset HTN was also a significant factor for longer TTF, compared to the pre-existing HTN [HR 0.72, 95% CI 0.64 - 0.82, p<0.001].
Conclusion
In patients treated with VSP inhibitors, both new-onset and pre-existing HTN are independent factors for a favorable clinical outcome, especially new-onset HTN after VSP inhibitors administration.

Combinations of alcohol-induced flushing with genetic polymorphisms of alcohol and aldehyde dehydrogenases and the risk of alcohol dependence in Japanese men and women. PLoS One 2021; 16:e0255276. [PMID: 34310648 PMCID: PMC8312924 DOI: 10.1371/journal.pone.0255276] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 07/14/2021] [Indexed: 12/22/2022] Open
Abstract
OBJECTIVE The risk of alcohol dependence (AD) in Japanese men and women was evaluated according to combinations of alcohol flushing and aldehyde dehydrogenase-2 (ALDH2, rs671) and alcohol dehydrogenase-1B (ADH1B, rs1229984) genotypes, all of which are known to determine AD susceptibility in Asians. Previous studies have focused on men, since women account for a smaller proportion of AD subjects. METHODS Case control studies were conducted between 3721 male and 335 female AD Japanese and 610 male and 406 female controls who were asked about their current or former tendency to experience facial flushing after drinking a glass of beer and underwent ALDH2 and ADH1B genotyping. The time at which alcohol-induced facial flushing tendencies had disappeared in former-flushing AD subjects was also evaluated. RESULTS Current alcohol flushing, the inactive ALDH2*1/*2 genotype, and the fast-metabolizing ADH1B*2 allele were less frequently found in the AD groups. Although alcohol flushing was strongly influenced by the ALDH2 and ADH1B genotypes, multiple logistic model showed that never or former flushing and the genotype combinations were independent strong risk factors of AD in men and women. Never or former flushing (vs. current flushing) markedly increased the odds ratios of AD in carriers of each of the ALDH2 and ADH1B genotype combinations. The temporal profiles for drinking and flushing in former-flushing AD subjects revealed that the flushing response disappeared soon after or before the start of habitual drinking during young adulthood, regardless of the ALDH2 genotype. CONCLUSION Although alcohol flushing is influenced by the ALDH2 and ADH1B genotypes, constitutional or acquired flushing tolerance is an independent susceptibility trait for AD. The combination of the alcohol flushing status and the ALDH2 and ADH1B genotypes can provide a better new strategy for AD risk assessment than the alcohol flushing status alone or the genotypes alone in Asian men and women.

Validation of improved 24-hour dietary recall using a portable camera among the Japanese population. Nutr J 2021; 20:68.

Abstract
BACKGROUND The collection of weighed food records (WFR) is a gold standard for dietary assessment. We propose using the 24-h recall method combined with a portable camera and a food atlas (24hR-camera). This combination overcomes the disadvantages of the 24-h dietary recall method. Our study examined the validity of the 24hR-camera method against WFR by comparing the results. METHODS Study subjects were 30 Japanese males, aged 31-58 years, who rarely cook and reside in the Tokyo metropolitan area. For validation, we compared the estimated food intake (24hR-camera method) and weighed food intake (WFR method). The 24hR-camera method uses digital photographs of all food consumed during a day, taken by the subjects, and a 24-h recall questionnaire conducted by a registered dietitian, who estimates food intake by comparing the participant's photographs with food atlas photographs. The WFR method involves a registered dietitian weighing each food item prepared for the subject to consume and any leftovers. Food intake was calculated for each food group and nutrient using the 24hR-camera vs. weighed methods. RESULTS Correlation coefficients between the estimated vs. weighed food intake were 0.7 or higher in most food groups but were low in food groups, such as oils, fats, condiments, and spices. The estimated intake of vegetables was significantly lower for the 24hR-camera method compared to the WFR method. For other food groups, the percentages of the mean difference between estimated vs. weighed food intake were -22.1% to 5.5%, with no significant differences between the methods (except for algae, which had a very low estimated intake). The correlation coefficients between the two methods were 0.774 for energy, and 0.855, 0.769, and 0.763 for the macronutrients, proteins, lipids, and carbohydrates, respectively, demonstrating high correlation coefficients: greater than 0.75. The correlation coefficients between the estimated vs. weighed for salt equivalents and potassium intake were 0.583 and 0.560, respectively, but no significant differences in intake were observed. CONCLUSIONS The 24hR-camera method satisfactorily estimated the intake of energy and macronutrients (except salt equivalents and potassium) in Japanese males and was confirmed as a useful method for dietary assessment.

Abstract
OBJECTIVES Oxidative stress is considered one of the etiologic factors involved in ulcerative colitis (UC), yet there is limited epidemiologic information regarding the relationship between antioxidant intake and the risk of UC. The aim of the present case-control study in Japan was to examine the association between intake of green and yellow vegetables, other vegetables, fruit, vitamin C, vitamin E, retinol, alpha-carotene, beta-carotene, and cryptoxanthin and UC risk. METHODS A total of 384 cases within 4 y of diagnosis with UC and 665 controls were included in the study. Data on dietary intake and confounders were obtained using a self-reported questionnaire. Information on dietary factors was collected using a 169-item semiquantitative food-frequency questionnaire. Adjustment was made for sex, age, pack-y of smoking, alcohol consumption, history of appendicitis, family history of UC, education level, and body mass index. RESULTS Higher intake levels of other vegetables, vitamin C, and retinol were independently associated with a reduced risk of UC. The adjusted odds ratio between extreme quartiles was 0.51 (95% confidence interval [CI], 0.34-0.76; P for trend ≤ 0.001) for other vegetables, 0.45 (95% CI, 0.30-0.69, P for trend ≤ 0.001) for vitamin C, and 0.64 (95% CI, 0.43-0.95, P for trend = 0.04) for retinol. There were no associations between intake of green and yellow vegetables, fruit, vitamin E, alpha-carotene, beta-carotene, or cryptoxanthin and UC risk (P for trend = 0.29, 0.56, 0.89, 0.20, 0.69, and 0.22, respectively). CONCLUSIONS Intake of other vegetables, vitamin C, and retinol was inversely associated with UC risk.

Abstract
4027 Background: In patients with resectable esophageal squamous cell carcinoma (SCC), the outcomes of chemoradiotherapy (CRT) for good responders after three courses of induction chemotherapy (IC) with docetaxel, cisplatin, and 5–fluorouracil (DCF chemotherapy) were unclear. Methods: Patients with clinical stage IB–III (UICC 7th) resectable esophageal SCC were eligible. IC included docetaxel 75 mg/m2 on day 1, cisplatin 75 mg/m2 on day 1, and 5–fluorouracil 750 mg/m2 on days 1–5, repeated every 3 weeks for 3 cycles. The response was evaluated after 2 and 3 courses of IC. Patients were considered to have a “remarkable response (RR)” if an endoscopic examination with a central review showed shrinking of the primary lesion equivalent to T1 and the short axis of the metastatic lymph nodes were all < 1 cm on computed tomography—in other words, down staging to T1N0M0 stage IA. Patients were considered to have a “poor response (POR)” if they had progressive disease or no signs of reduction. Patients who did not achieve RR or POR were deemed to have “limited partial response (LPR)”. CRT was administered to patients who achieved RR, and surgery was performed in patients who achieved LPR or POR. CRT included cisplatin 75 mg/m2 on day 1 and 5–fluorouracil 1000 mg/m2 on days 1–4, repeated every 4 weeks for 2 cycles. Radiotherapy was administered as 50.4 Gy in 28 fractions. The primary endpoint was a 1–year progression free survival (PFS) for RR followed by CRT. Results: A total of 92 patients were enrolled. Two patients with non–SCC (n = 1) and distant metastasis (n = 1) were excluded. Therefore, 90 patients were included in the analysis group. Although 1 patient could not continue IC due to renal failure, the remaining 89 patients completed 3 courses of IC. The response after IC were RR in 58.4% (52/89), LPR in 41.6% (37/89), and POR in 0.0% (0/89). Three patients who achieved RR underwent surgery owing to renal dysfunction (n = 1), curative irradiation difficulty due to intestinal malrotation (n = 1), and CRT refusal (n = 1). Six patients who achieved LPR underwent CRT owing to surgery refusal (n = 3), unresectable tumors (n = 2), and respiratory dysfunction due to emphysema (n = 1). The complete response rate for RR followed by CRT was 89.8%. During the median follow–up period of 33 months (range: 1–85), the 1 and 3–years overall survival (OS) for the analysis group were 96.6% and 74.1%, respectively. The 1 and 3–years organ preservation survival for the analysis group were 56.8% and 45.3%, respectively. The 1 and 3–years OS for RR followed by CRT (n = 49) vs. LPR followed by surgery (n = 31) were 100% vs. 93.1% and 83.7% vs. 62.8%, respectively (p = 0.06). The 1 and 3–years PFS for RR followed by CRT were 89.8% and 70.0%, respectively. Conclusions: Three courses of DCF chemotherapy followed by CRT is an effective treatment for patients with resectable esophageal SCC who respond to the IC regimen. Clinical trial information: 8086.

Abstract
Head and neck cancers, especially in hypopharynx and oropharynx, are often detected at advanced stage with poor prognosis. Narrow band imaging enables detection of superficial cancers and transoral surgery is performed with curative intent. However, pathological evaluation and real‐world safety and clinical outcomes have not been clearly understood. The aim of this nationwide multicenter study was to investigate the safety and efficacy of transoral surgery for superficial head and neck cancer. We collected the patients with superficial head and neck squamous cell carcinoma who were treated by transoral surgery from 27 hospitals in Japan. Central pathology review was undertaken on all of the resected specimens. The primary objective was effectiveness of transoral surgery, and the secondary objective was safety including incidence and severity of adverse events. Among the 568 patients, a total of 662 lesions were primarily treated by 575 sessions of transoral surgery. The median tumor diameter was 12 mm (range 1–75) endoscopically. Among the lesions, 57.4% were diagnosed as squamous cell carcinoma in situ. The median procedure time was 48 minutes (range 2–357). Adverse events occurred in 12.7%. Life‐threatening complications occurred in 0.5%, but there were no treatment‐related deaths. During a median follow‐up period of 46.1 months (range 1–113), the 3‐year overall survival rate, relapse‐free survival rate, cause‐specific survival rate, and larynx‐preservation survival rate were 88.1%, 84.4%, 99.6%, and 87.5%, respectively. Transoral surgery for superficial head and neck cancer offers effective minimally invasive treatment. Clinical trials registry number: UMIN000008276.

A multicenter cohort study of osimertinib compared with afatinib as first-line treatment for EGFR-mutated non-small-cell lung cancer from practical dataset: CJLSG1903. ESMO Open 2021; 6:100115. [PMID: 33984681 PMCID: PMC8134659 DOI: 10.1016/j.esmoop.2021.100115] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 03/14/2021] [Accepted: 03/19/2021] [Indexed: 11/25/2022] Open
Abstract
Background FLAURA, the prospective trial of osimertinib as a first-line therapy compared with first-generation epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), did not show superior survival benefit for osimertinib in either the subgroup of Asians or the subgroup with the L858R mutation. In addition, the superiority of osimertinib compared with second-generation EGFR-TKI is thus far unclear. Patients and methods We reviewed the clinical data of all consecutive patients who were treated with osimertinib or afatinib as first-line therapy between May 2016 and October 2019 from 15 institutions in Japan. We defined the groups based on first-line EGFR-TKI as the afatinib group and the osimertinib group. Outcomes included time to discontinuation of any EGFR-TKI (TD-TKI), overall survival (OS), and time to treatment failure, with propensity score analysis carried out as an exploratory analysis in the survival and subgroup analyses. Results A total of 554 patients were enrolled. Data on 326 patients in the osimertinib group, and 224 patients in the afatinib group were analyzed. TD-TKI adjusted by propensity score in the afatinib and osimertinib groups was 18.6 months (95% confidence interval 15.8 to 22.0) and 20.5 months (95% confidence interval 13.8 to not reached), respectively, without significant difference (P = 0.204). OS adjusted by propensity score favored the afatinib group with a significant difference (P = 0.018). Subgroup analysis with propensity score showed that patients with L858R and without brain metastasis had superior survival benefit with afatinib compared with osimertinib (P < 0.001). Conclusions TD-TKI in the afatinib group was not significantly prolonged compared with the osimertinib group in the practical data. In the exploratory analysis of patients with L858R-mutated non-small-cell lung cancer without brain metastasis, afatinib showed more benefit in OS over osimertinib. The large-scale practical data of 550 patients who were treated with osimertinib or afatinib as first-line therapy were analyzed. The superiority of osimertinib compared with afatinib could not be demonstrated in all populations. Osimertinib therapy showed effectiveness in patients with brain metastasis. Afatinib therapy showed potential benefit in patients with L858R mutation and without brain metastasis.

Factors associated with birthweight decline in Japan (1980-2004). BMC Pregnancy Childbirth 2021; 21:337. [PMID: 33906616 PMCID: PMC8080357 DOI: 10.1186/s12884-021-03819-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 04/20/2021] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND Birthweight has been declining consistently for more than 30 years in Japan. This rapid rise in low birthweight is one of the worst among the countries of the Organization for Economic Co-operation and Development. We examined potential determinants of birthweight decline in Japan. METHODS We used population-based birth certificate data from vital statistics records and retrieved 40,968,266 birth certificates of neonates born between 1980 and 2004. We analyzed time trends using linear regression analysis in examining whether the decline in birthweight could be explained by obstetrical variables such as gestational age and multiple gestations. RESULTS From 1980 to 2004, we observed a decline in mean birthweight with a yearly effect of - 8.07 g, which became steeper after 1985, persisted until 1999, and plateaued thereafter. After adjusting for gestational age, gender, birth order, multiple gestations, and fathers' age, the yearly effect between 1980 and 2004 persisted at - 5.13 g. CONCLUSION Recent decreases in birthweight among Japanese neonates were not fully explained by trends in gestational age, gender, birth order, multiple gestations, and fathers' age. Thus, additional factors such as pre-pregnancy maternal body mass index (BMI) and maternal diet should be considered. Reducing the rate of induced deliveries and improving the BMI or diet of young women should be a public health priority.

Difference and Variance in Nutrient Intake by Age for Older Adults Living Alone in Japan: Comparison of Dietary Reference Intakes for the Japanese Population. Nutrients 2021; 13:nu13051431. [PMID: 33922719 PMCID: PMC8146330 DOI: 10.3390/nu13051431] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2021] [Revised: 04/18/2021] [Accepted: 04/21/2021] [Indexed: 11/16/2022] Open
Abstract
This study aimed to estimate the distribution of usual intakes in protein, sodium, potassium, and calcium by age group and assessed whether proportions of deficiencies/excesses of each nutrient would occur more in older age via a comparison with the dietary reference intakes for the Japanese population (DRIs_J). A cross-sectional analysis was conducted using a database of the 2-day nutrient intake of 361 Japanese people aged 65-90 years. The AGEVAR MODE was used to estimate usual intake. Percentile curves using estimated distribution by sex and age and usual nutrient intake were compared to those of the DRIs_J. The usual intake of protein (male and female) and potassium and calcium (female) were lower with older age. Within-individual variance of protein in female (p = 0.037) and calcium in male (p = 0.008) subjects were considerably lower with older age. The proportion of deficiencies in protein (male and female), potassium (female), and calcium (female) were higher with older age. However, the proportion of people with excess salt (converted from sodium; male and female) did not differ by age. The variances found herein could be important for enhancing the understanding of differences in dietary intake by age.

A comparison in the ability to detect diabetic retinopathy between fasting plasma glucose and HbA1c levels in a longitudinal study. Endocrinol Diabetes Metab 2021; 4:e00196. [PMID: 33532623 PMCID: PMC7831218 DOI: 10.1002/edm2.196] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 09/27/2020] [Accepted: 10/03/2020] [Indexed: 11/19/2022] Open
Abstract
Aims The relationship between HbA1c and diabetic retinopathy is expected to differ between different races. In this study, we verified which of HbA1c and fasting plasma glucose (FPG) is more effective for detecting the diabetic retinopathy longitudinally in a Japanese population. Materials and Methods The study subjects underwent health examinations twice (including eye test and questionnaire of lifestyle and health) in 2008-2009 (baseline) and in 2012-2013 (4-year follow-up). Both non-DM and DM patients at baseline were included as the participants. Of these participants, who had not been diagnosed with retinopathy at the baseline survey (n = 2427; 2150 men and 277 women) had eye fundus photographs taken four years later (follow-up survey). The odds ratios of incidence of retinopathy according to the eight groups of FPG and HbA1c were estimated using multiple logistic regression analysis adjusted for sex and age. Receiver operator characteristic analysis was used to evaluate each value associated with the presence or absence of retinopathy. Results The odds ratios (95% confidence intervals) of incidence of retinopathy by HbA1c level categories, in ascending order, were 1.0 (ref.), 5.66 (1.14-28.26), 1.69 (0.24-12.04), 3.03 (0.50-18.28), 1.04 (0.09-11.59), 4.73 (0.78-28.69), 4.12 (0.74-22.85) and 24.47 (5.61-106.75). For both FPG and HbA1c levels, the odds ratio for the development of retinopathy increased linearly with the increases in the levels FPG and HbA1c, and no clear threshold was observed. The AUC values (SE) for FPG and HbA1c were almost the same, at 0.750 (0.046) and 0.732 (0.048). Conclusions It was clarified that the higher the level of FPG and HbA1c was, the higher the incidence of retinopathy after 4 years was. There was no clear threshold. The detection ability of the incidence of retinopathy was almost the same between FPG and HbA1c, suggesting it is possible to detect the risk of retinopathy by HbA1c only.

Detection of Glaucoma and Other Vision-Threatening Ocular Diseases in the Population Recruited at Specific Health Checkups in Japan. Clin Epidemiol 2020; 12:1381-1388. [PMID: 33364847 PMCID: PMC7751581 DOI: 10.2147/clep.s273016] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 11/18/2020] [Indexed: 11/23/2022] Open
Abstract
Background The efficacy of vision screening for adults has not been well established. The present study aimed to investigate the prevalence of vision-threatening ocular diseases, including glaucoma, among subjects who participated in specific health checkups in Japan. Methods This cross-sectional study included 1360 individuals who underwent comprehensive ophthalmic examinations at 16 ophthalmology clinics located in three municipalities. We surveyed the study participants using a questionnaire. The participants also underwent visual acuity and refraction tests, intraocular pressure tests, slit-lamp microscopy, fundus examinations, fundus photography, optical coherence tomography, and static perimetry. Results The mean age of the subjects was 63.7 ± 8.7 years (range, 40–74 years). Among the 1360 participants, 168 (12.4%) were diagnosed with glaucoma and 33 (2.4%) with preperimetric glaucoma. Cataracts were seen in 741 participants (54.5%), and 77 (5.7%) were diagnosed with clinically significant cataracts. Retinal diseases included macular degeneration (1.2%), diabetic retinopathy (1.0%), chorioretinal atrophy (0.5%), macular epiretinal membrane (2.9%), branch retinal vein occlusion (0.7%), and others (2.0%). Regarding the type of glaucoma, 93.5% of participants with glaucoma were diagnosed with open-angle glaucoma in a broad sense (81.0% with normal-tension glaucoma and 12.5% with primary open-angle glaucoma). Multivariate analysis showed that male sex, age, systemic comorbidities, and myopia were significant risk factors for open-angle glaucoma. Conclusion Many adults with ocular diseases were screened by ophthalmic checkups. The addition of simultaneous ophthalmic checkups to specific health checkups could be an effective measure for the prevention of visual impairment in the older population.

Risk factors for esophageal iodine-unstained lesions and changing trends among Japanese alcohol-dependent men (2003-2018). Cancer Sci 2020; 112:734-743. [PMID: 33249700 PMCID: PMC7894006 DOI: 10.1111/cas.14753] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 11/25/2020] [Accepted: 11/25/2020] [Indexed: 12/16/2022] Open
Abstract
Globally, a decreasing incidence of male esophageal squamous cell carcinoma (ESCC) has been observed in recent decades. We evaluated the determinants of esophageal distinct iodine-unstained lesions (DIULs), high-cancer-risk lesions and ESCC, among 3858 Japanese alcohol-dependent men (40-79 years) who underwent chromoendoscopic screening between 2003 and 2018. The initial screening detected DIULs ≥ 5 mm in 541 patients (dysplasia in 319 and SCC in 129) and multiple DIULs in 640. The detection rates for DIULs and chronic atrophic gastritis (CAG), pack-years, and the mean corpuscular volume (MCV) decreased over the course of the study period, while the detection of hiatal hernia and/or columnar-lined esophagus (HH/CLE) and the carriers of inactive heterozygous aldehyde dehydrogenase-2 (ALDH2, rs671) increased. Multiple logistic regression analyses showed that an older age, larger number of pack-years, smaller body mass index, larger MCV, presence of a slow-metabolizing alcohol dehydrogenase-1B genotype (rs1229984), presence of an inactive heterozygous ALDH2 genotype, and more advanced degree of CAG increased the odds ratios (ORs) for DIULs, while the 2008-2013 and 2014-2018 screening periods had lower ORs for DIULs than the 2003-2007 screening period. The presence of HH/CLE decreased the OR for multiple DIULs and was associated with a more proximal location of ESCC. In conclusion, the detection of DIULs in an alcohol-dependent population decreased between 2003 and 2018. In addition to reported determinants of ESCC, CAG and HH/CLE were associated with the risk of DIULs. Enigmatically, however, the decline in the detection of DIULs was not adequately explained by these factors and warrants further research.

Effectiveness of planned surveillance for detecting second primary head and neck cancers after endoscopic resection of esophageal squamous cell carcinoma. Jpn J Clin Oncol 2020; 50:1162-1167. [PMID: 32533160 DOI: 10.1093/jjco/hyaa087] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2020] [Accepted: 05/19/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Second primary head and neck cancers after endoscopic resection of esophageal squamous cell carcinoma adversely affect patients' outcomes and the quality of life; however, an adequate surveillance schedule remains unclear. METHODS We analyzed 330 patients with early esophageal squamous cell carcinoma who underwent endoscopic resection and were registered in the multicenter cohort study to evaluate adequate surveillance for detection of second primary head and neck cancers. Gastrointestinal endoscopists examined the head and neck regions after 3-6 months of endoscopic resection for esophageal squamous cell carcinoma and subsequently every 6 months. An otolaryngologist also examined the head and neck regions at the time of endoscopic resection for esophageal squamous cell carcinoma and at 12 months intervals thereafter. RESULTS During the median follow-up period of 49.4 months (1.3-81.2 months), 33 second primary head and neck cancers were newly detected in 20 patients (6%). The tumor site was as follows: 22 lesions in the hypopharynx, eight lesions in the oropharynx, two lesions in larynx and one lesion in the oral cavity. The 2-year cumulative incidence rate of second primary head and neck cancers was 3.7%. Among them, 17 patients with 29 lesions were treated by transoral surgery. One patient with two synchronous lesions was treated by radiotherapy. Two lesions in two patients were not detected after biopsy. All patients were cured with preserved laryngeal function. CONCLUSIONS Surveillance by gastrointestinal endoscopy every 6 months and surveillance by an otolaryngologist every 12 months could detect second primary head and neck cancers at an early stage, thereby facilitating minimally invasive treatment.

Abstract
BACKGROUND Prospectively collected long-term data of patients undergoing endoscopic resection for superficial esophageal squamous cell carcinoma (ESCC) are limited. The aim of this study was to determine the prospectively collected long-term outcomes of endoscopic resection for ESCC as a secondary analysis of the Japan Esophageal Cohort (JEC) study. METHODS Patients who underwent endoscopic resection of intramucosal ESCC at 16 institutions between September 2005 and May 2010 were enrolled in the JEC study. All patients underwent endoscopic examination with iodine staining at 3 and 6 months after resection, and every 6 months thereafter. We investigated clinical courses after endoscopic resection, survival rates, and cumulative incidence of metachronous ESCC. RESULTS 330 patients (mean age 67.0 years) with 396 lesions (mean size 20.4 mm) were included in the analysis. Lesions were diagnosed as high-grade intraepithelial neoplasia in 17.4 % and as squamous cell carcinoma in 82.6 % (limited to epithelium in 28.4 %, to lamina propria in 55.4 %, and to muscularis mucosa in 16.2 %). En bloc resection was achieved in 291 (73.5 %). The median follow-up period was 49.4 months. Local recurrences occurred in 13 patients (3.9 %) and were treated by endoscopic procedures. Lymph node metastasis occurred in two patients (0.6 %) after endoscopic resection. The 5-year overall, disease-specific, and metastasis-free survival rates were 95.1 %, 99.1 %, and 94.6 %, respectively. The 5-year cumulative incidence rate of metachronous ESCC was 25.7 %. CONCLUSIONS Our study demonstrated that endoscopic resection is an effective treatment for intramucosal ESCC, with favorable long-term outcomes.
