Abstract
PURPOSE This study aimed to examine the potential benefit of sodium-glucose cotransporter 2 (SGLT2) inhibitors for patients with metabolic dysfunction-associated fatty liver disease (MAFLD) and diabetes mellitus (DM) using a real-world database. METHODS We analyzed individuals with MAFLD and DM newly initiated on SGLT2 or dipeptidyl peptidase 4 (DPP4) inhibitors from a large-scale administrative claims database. The primary outcome was the change in the fatty liver index (FLI) assessed using a linear mixed-effects model from the initiation of SGLT2 or DPP4 inhibitors. A propensity score-matching algorithm was used to compare the change in FLI among SGLT2 and DPP4 inhibitors. RESULTS After propensity score matching, 6547 well-balanced pairs of SGLT2 and 6547 DPP4 inhibitor users were created. SGLT2 inhibitor use was associated with a greater decline in FLI than DPP4 inhibitor use (difference at 1-year measurement, - 3.8 [95% CI - 4.7 to - 3.0]). The advantage of SGLT2 inhibitor use over DPP4 inhibitor use for improvement in FLI was consistent across subgroups. The relationship between SGLT2 inhibitors and amelioration of FLI was comparable between individual SGLT2 inhibitors. CONCLUSIONS Our analysis using large-scale real-world data demonstrated the potential advantage of SGLT2 inhibitors over DPP4 inhibitors in patients with MAFLD and DM.

Abstract
BACKGROUND The association between weight loss and subsequent functional decline is uncertain. The study aims to elucidate the association between weight loss over a year and subsequent functional decline requiring assistance in performing their activities of daily living in older individuals. METHODS The study used data from the publicly funded Long-Term Care Insurance service in Japan, which provides coverage for long-term care services for individuals unable to perform activities of daily living due to physical or cognitive impairment. The study enrolled people born in or before 1949, who underwent health checkups in both 2014 and 2015. The participants were followed from 2015 to the worsening of functional decline requiring long-term care services, death, or February 28, 2019, whichever occurred first. The risk of subsequent functional decline in each weight loss category was estimated using a Cox regression model adjusted for age, sex, baseline body mass index, smoking, and Charlson comorbidity index. RESULTS We identified 67,452 eligible individuals from the database. The median follow-up period was 1,284 days. The hazard ratios (95 % confidence interval) of functional decline for -1 %, -2 %, -3 %, -4 %, and ≤-5% weight change compared to 0 % weight change were 1.17 (1.03-1.32), 1.26 (1.11-1.43), 1.29 (1.12-1.49), 1.61 (1.39-1.87), and 1.79 (1.58-1.99), respectively. CONCLUSIONS AND IMPLICATIONS Older people with weight loss of 1 % or more were at risk of functional decline. Close weight monitoring may serve as an easy and inexpensive means of identifying older individuals at risk of functional decline.

Abstract
Hypertension is the leading risk factor for cardiovascular disease (CVD). Although cancer has recently been increasingly recognized as a novel risk factor for CVD events, little is known about whether co-morbid cancer in individuals with hypertension could further increase the risk of CVD events. We sought to determine the association between the cancer history and the risk of CVD in individuals with hypertension. We retrospectively analyzed a large cohort of 747,620 individuals diagnosed with hypertension from January 2005 through May 2022 using the JMDC Claims Database. Composite CVD events, including myocardial infarction (MI), angina pectoris (AP), stroke, heart failure (HF), and atrial fibrillation (AF), were recorded, and a Cox proportional hazard regression was done to estimate hazard ratios (HR) based on the history of cancer and chemotherapy. 26,531 individuals had a history of cancer. During the mean follow-up period of 1269 ± 962 days, 67,154 composite CVD events were recorded. Compared with individuals without a cancer history, cancer survivors had a higher risk of developing composite CVD events (HR: 1.21, 95% confidence interval [CI]: 1.17-1.26). The HRs (95% CIs) associated with cancer history for MI, AP, stroke, HF, and AF were 1.07 (0.90-1.27), 1.13 (1.06-1.20), 1.14 (1.06-1.24), 1.31 (1.25-1.38), and 1.22 (1.10-1.35), respectively. Lastly, individuals who had received chemotherapy for cancer had a particularly higher risk of developing CVD compared to those who did not undergo chemotherapy. A history of cancer was associated with a greater risk of developing CVD among individuals with hypertension.

Abstract
BACKGROUND There have been scarce epidemiological data on the relationship between inflammatory bowel disease and the incidence of Immunoglobulin A (IgA) nephropathy. In this study, we assessed whether inflammatory bowel disease was associated with a higher risk of developing IgA nephropathy using a large-scale epidemiological cohort. METHODS We retrospectively analyzed 4,311,393 adults enrolled in the JMDC Claims Database (previously known as the Japan Medical Data Center database), a nationwide epidemiological database in Japan. The definitions of IgA nephropathy and inflammatory bowel disease (ulcerative colitis or Crohn's disease) were based on International Classification of Diseases-10th Revision codes. Individuals who had a prior history of IgA nephropathy were excluded. Study participants were categorized into two groups according to the presence of inflammatory bowel disease. Clinical outcomes were collected between January 2005 and May 2022. The primary outcome was incident IgA nephropathy. RESULTS Median (interquartile range) age was 44 (36-53) years, and 2,497,313 (58%) were men. Inflammatory bowel disease was observed in 18,623 individuals (0.4%). Over a median follow-up of 1,089 (532-1,797) days, there were 2,631 incidences of IgA nephropathy and 22 incidences in individuals without and with inflammatory bowel disease, yielding incident ratios with 95% confidence intervals of 1.74 (1.68-1.81) and 3.43 (2.26-5.21), respectively. Kaplan-Meier curves and the log-rank test showed that a cumulative incidence of IgA was higher in individuals with inflammatory bowel disease compared to those without (log-rank p=0.003). Multivariable Cox regression analysis demonstrated that individuals with inflammatory bowel disease were at higher risk for incident IgA nephropathy (Hazard ratio 1.96, 95% confidence interval 1.29-2.99). CONCLUSIONS We demonstrated the potential association of inflammatory bowel disease with higher risk of developing IgA nephropathy in a general population.

Abstract
Although several randomized clinical trials have reported the potential benefit of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in reducing blood pressure (BP), whether SGLT2i can reduce incident hypertension is unknown. We analyzed individuals with diabetes who were newly prescribed SGLT2i or dipeptidyl peptidase 4 inhibitors (DPP4i) in a large-scale epidemiological database. The primary outcome was the incidence of hypertension. A propensity score matching algorithm was employed to compare the subsequent development of hypertension between the SGLT2i and DPP4i groups. After propensity score matching, 5708 well-balanced pairs of SGLT2i and DPP4i users were identified. SGLT2i administration was associated with a reduced risk of hypertension (HR 0.91, 95% CI: 0.84-0.97). The advantage of SGLT2i use over DPP4i use for incident hypertension was generally consistent in several sensitivity analyses, and subgroup analyses showed that SGLT2i use was significantly associated with a lower risk of hypertension in men, patients with baseline HbA1c of <7.5%, and baseline systolic blood pressure ≥127 mmHg. Our investigation using nationwide real-world data demonstrated the potential advantage of SGLT2i over DPP4i in reducing the development of hypertension in individuals with diabetes.

Abstract
BACKGROUND Kampo, a Japanese herbal medicine, is approved for the treatment of various symptoms/conditions under national medical insurance coverage in Japan. However, the contemporary nationwide status of Kampo use among patients with acute cardiovascular diseases remains unknown.Methods and Results: Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified 2,547,559 patients hospitalized for acute cardiovascular disease (acute myocardial infarction, heart failure, pulmonary embolism, or aortic dissection) at 1,798 hospitals during the fiscal years 2010-2021. Kampo medicines were used in 227,008 (8.9%) patients, with a 3-fold increase from 2010 (4.3%) to 2021 (12.4%), regardless of age, sex, disease severity, and primary diagnosis. The top 5 medicines used were Daikenchuto (29.4%), Yokukansan (26.1%), Shakuyakukanzoto (15.8%), Rikkunshito (7.3%), and Goreisan (5.5%). From 2010 to 2021, Kampo medicines were initiated earlier during hospitalization (from a median of Day 7 to Day 3), and were used on a greater proportion of hospital days (median 16.7% vs. 21.4%). However, the percentage of patients continuing Kampo medicines after discharge declined from 57.9% in 2010 to 39.4% in 2021, indicating their temporary use. The frequency of Kampo use varied across hospitals, with the median percentage of patients prescribed Kampo medications increasing from 7.7% in 2010 to 11.5% in 2021. CONCLUSIONS This nationwide study demonstrates increasing Kampo use in the management of acute cardiovascular diseases, warranting further pharmacoepidemiological studies on its effectiveness.

Abstract
BACKGROUND Hypertension is a major cause of cardiovascular disease (CVD). In patients with hypertension, unawareness of the disease often results in poor blood pressure control and increases the risk of CVD. However, data in nationwide surveys regarding the proportion of unaware individuals and the implications of such on their clinical outcomes are lacking. We aimed to clarify the association between unawareness of being prescribed antihypertensive medications among individuals taking antihypertensive medications and the subsequent risk of developing CVD.Methods and Results: This retrospective cohort study analyzed data from the JMDC Claims Database, including 313,715 individuals with hypertension treated with antihypertensive medications (median age 56 years). The primary endpoint was a composite of myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. Overall, 19,607 (6.2%) individuals were unaware of being prescribed antihypertensive medications. During the follow-up period, 33,976 composite CVD endpoints were documented. Despite their youth, minimal comorbidities, and the achievement of better BP control with a reduced number of antihypertensive prescriptions, unawareness of being prescribed antihypertensive medications was associated with a greater risk of developing composite CVD. Hazard ratios of unawareness of being prescribed antihypertensive medications were 1.16 for myocardial infarction, 1.25 for angina pectoris, 1.15 for stroke, 1.36 for heart failure, and 1.28 for atrial fibrillation. The results were similar in several sensitivity analyses, including the analysis after excluding individuals with dementia. CONCLUSIONS Among individuals taking antihypertensive medications, assessing the awareness of being prescribed antihypertensive medications may help identify those at high risk for CVD-related events.

Abstract
BACKGROUND Some patients with diabetes are unaware that they are prescribed medications for diabetes. The purpose of this study is to determine, using a Japanese nationwide epidemiologic database, the association between unawareness of being prescribed medication and the risk of developing cardiovascular disease (CVD) in patients with diabetes. METHODS This observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2022, including 94,048 patients with diabetes treated with medications. The primary endpoint was a composite endpoint including myocardial infarction (MI), stroke, heart failure (HF), and atrial fibrillation (AF). RESULTS We identified 7561 composite CVD endpoints during a mean follow-up of 1199 ± 902 days. Overall, 7779 (8.3 %) patients were unaware of being prescribed medications for diabetes. Those who did not know they were prescribed drugs were younger and had better glycemic control, but these individuals were at higher risk of developing combined CVD [hazard ratio (HR) 1.13, 95 % confidence interval (95 % CI) 1.04-1.22]. HRs of unawareness of being prescribed medications were 1.33 (95 % CI 1.06-1.68) for MI, 1.13 (95 % CI 0.97-1.31) for stroke, 1.10 (95 % CI 1.00-1.21) for HF, and 1.19 (95 % CI 0.97-1.47) for AF, respectively. CONCLUSIONS In patients with diabetes taking medications for diabetes, even if they are young and have good glycemic control, it is important that they receive adequate education from their healthcare providers to accurately identify their treatment status.

Abstract
AIM This study aimed to elucidate the impact of periodontal therapy on glycaemic control in individuals with type 2 diabetes and various baseline blood glucose levels using a large-scale claims database from Japan. MATERIALS AND METHODS Using the JMDC Claims Database, we identified individuals with type 2 diabetes who underwent health check-ups in the fiscal years 2018 or 2019 and were followed up until the next year's health check-up. We conducted a weighted cohort analysis using stabilized inverse probability weights for treatment and censoring to estimate the effect of periodontal therapy on changes in haemoglobin A1c levels within a year. Analysis was done for different baseline haemoglobin A1c categories: 6.5%-6.9%, 7.0%-7.9% and ≥8.0%. RESULTS Of the 4279 insured persons included in the study, 957 received periodontal therapy. Overall, there was a tendency towards improved glycaemic control among those who received periodontal therapy. Participants with baseline haemoglobin A1c levels of 7.0%-7.9% who received periodontal therapy exhibited significantly better glycaemic control compared with those without dental visits (difference; -0.094 [95% confidence interval: -0.181 to -0.007]). CONCLUSIONS Periodontal therapy may improve glycaemic control in individuals with diabetes, especially in those with haemoglobin A1c levels ≥7.0%.

Abstract
Background Depression is a known risk factor for cardiovascular disease (CVD), but the potential sex differences in this association remain unclear. Objectives The aim of this study was to investigate the association between depression and subsequent CVD events, and to explore potential sex differences. Methods The authors conducted a retrospective analysis using the JMDC Claims Database between 2005 and 2022. The study population included 4,125,720 individuals aged 18 to 75 years without a history of cardiovascular disease or renal failure and missing data at baseline. Participants were followed up for a mean of 1,288 days to assess the association between depression and subsequent CVD events, such as myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. Results Our analysis revealed a significant association between depression and subsequent composite CVD events in both men and women, with a stronger association observed in women. The HR for the composite endpoint was 1.64 (95% CI: 1.59-1.70) in women and 1.39 (95% CI: 1.35-1.42) in men after multivariable adjustment (P for interaction <0.001). Furthermore, the individual components of the composite endpoint were also associated with depression in both men and women, each of which was also observed to be more strongly associated in women. Conclusions Our study provides evidence of a significant association between depression and subsequent CVD events in both men and women, with a more pronounced association observed in women. These findings highlight the importance of addressing depression and tailoring prevention and management strategies according to sex-specific factors.

Abstract
BACKGROUND Scarce data on factors related to discharge disposition in patients hospitalized for acute heart failure (AHF) were available, and we sought to develop a parsimonious and simple predictive model for non-home discharge via machine learning. METHODS This observational cohort study using a Japanese national database included 128,068 patients admitted from home for AHF between April 2014 and March 2018. The candidate predictors for non-home discharge were patient demographics, comorbidities, and treatment performed within 2 days after hospital admission. We used 80% of the population to develop a model using all 26 candidate variables and using the variable selected by 1 standard-error rule of Lasso regression, which enhances interpretability, and 20% to validate the predictive ability. RESULTS We analyzed 128,068 patients, and 22,330 patients were not discharged to home; 7,879 underwent in-hospital death and 14,451 were transferred to other facilities. The machine-learning-based model consisted of 11 predictors, showing a discrimination ability comparable to that using all the 26 variables (c-statistic: 0.760 [95% confidence interval, 0.752-0.767] vs. 0.761 [95% confidence interval, 0.753-0.769]). The common 1SE-selected variables identified throughout all analyses were low scores in activities of daily living, advanced age, absence of hypertension, impaired consciousness, failure to initiate enteral alimentation within 2 days and low body weight. CONCLUSIONS The developed machine learning model using 11 predictors had a good predictive ability to identify patients at high risk for non-home discharge. Our findings would contribute to the effective care coordination in this era when HF is rapidly increasing in prevalence.

Abstract
BACKGROUND The Late-Stage Elderly Questionnaire has been incorporated into health assessments for older adults in Japan, encompassing three self-administered questions on subjective physical function: subjective gait speed decline, recent fall history, and exercise habits. Nevertheless, its efficacy in predicting new fracture occurrences remains uncertain. METHODS This retrospective cohort study utilized Japan's DeSC database, a large commercially available claims database. Participants were older adults aged ≥75 years and provided complete responses to the Late-Stage Elderly Questionnaire at health check-ups. We performed two Cox regression analyses for new fractures based on the responses to the three questions (Model 1) and on age, sex, and responses to the three questions (Model 2). The predictive abilities of the 1-year occurrence of new fractures were compared between the two models. RESULTS Of 11 683 eligible older adults, 927 (7.93%) experienced new fractures. Model 1 revealed significant associations between new fractures and subjective gait speed decline (hazard ratio [HR], 1.63; 95% confidence interval [CI], 1.40-1.89), recent fall history (HR, 2.03; 95% CI, 1.77-2.33), and absence of exercise habits (HR, 1.29; 95% CI, 1.13-1.47). Model 2 demonstrated superior predictive ability (area under the curve, 0.677; 95% CI, 0.659-0.695) compared with Model 1 (area under the curve, 0.633; 95% CI, 0.614-0.652), with a net reclassification improvement of 0.383 (95% CI, 0.317-0.449). CONCLUSION Three subjective physical well-being factors were significantly associated with new fracture development in older adults. These results suggest that the three-question assessment may be a valuable screening tool for identifying new fractures. Geriatr Gerontol Int 2024; 24: 337-343.

Abstract
AIM To compare the risk of developing kidney outcomes with use of glucagon-like peptide-1 receptor agonists (GLP-1RAs) versus use of sodium-glucose cotransporter-2 (SGLT2) inhibitors among individuals with diabetes. MATERIALS AND METHODS In this retrospective observational study, we analysed 12 338 individuals with diabetes who newly initiated SGLT2 inhibitors or GLP-1RAs using data from the JMDC claims database. The primary outcome was change in the estimated glomerular filtration rate (eGFR), estimated using a linear mixed-effects model. A 1:4 propensity-score-matching algorithm was used to compare the changes in eGFR between GLP-1RA and SGLT2 inhibitor users. RESULTS After propensity-score matching, 2549 individuals (median [range] age 52 [46-58] years, 80.6% men) were analysed (510 GLP-1RA new users and 2039 SGLT2 inhibitor new users). SGLT2 inhibitor use was associated with a slower eGFR decline when compared with GLP-1RA use (-1.41 [95% confidence interval -1.63 to -1.19] mL/min/1.73 m2 vs. -2.62 [95% confidence interval -3.15 to -2.10] mL/min/1.73 m2). CONCLUSIONS Our analysis demonstrates the potential advantages of SGLT2 inhibitors over GLP-1RAs in terms of kidney outcomes in individuals with diabetes.

Abstract
The adsorption behavior of poly(methyl acrylate) (PMA)-based polymer additives and their mechanical response under fluid lubrication in narrow gaps were investigated by using neutron reflectometry, microchannel devices, and the narrow gap viscometer. The surface adsorption layer formed by the polymer additive in a stationary field that was investigated by neutron reflectometry was only about 3 nm thick. On the other hand, when the sample oil containing the polymer additive was flowed into the microchannel device with channels about 500 nm deep, the adsorption layer grew over a long period of time and eventually formed a layer that appeared to be more than 100 nm thick. The mechanical response was measured during one-directional rotation with a constant gap length by using the narrow gap viscometer. The results showed that the effective viscosity increased in the low shear rate range. The same behavior was also observed in the reciprocating rotational tests, where the mechanical response showed a distinctive distortion only when the shear rate was low near 0 rpm. The results of the neutron reflectometer, incorporating the narrow gap viscometer, showed no effect of the rotational speed with regard to the structure of the homogeneous layer over a large area. However, the discrepancy between the reflectivity profile and the fitting curve became progressively more pronounced with time, confirming the formation of inhomogeneous structures with time. It is finally suggested that the inhomogeneous structure is due to the formation of local aggregates by PMA molecules, and it acts as flow resistance only in the low shear rate, resulting in an increase in effective viscosity.

Abstract
BACKGROUND The risk of subsequent cardiovascular disease (CVD) is high in cancer survivors. Although metabolic syndrome is an established risk factor for CVD, its association with cancer survivors has not yet been established. This study aimed to clarify whether metabolic syndrome is associated with subsequent CVD risk in patients with cancer using a nationwide epidemiological dataset. METHODS We retrospectively analysed 53 510 patients with a history of breast, colorectal, or stomach cancer, which is reportedly a major site for developing cancer in Japan. Study participants were categorized into two groups based on the presence of metabolic syndrome, defined using the Japanese criteria (high waist circumference and ≥2 metabolic parameters including elevated blood pressure, elevated triglycerides, reduced high-density lipoprotein cholesterol, or elevated fasting plasma glucose). The clinical outcomes were collected between 2005 and 2021. The primary endpoint was defined as the composite CVD outcome, including myocardial infarction, angina pectoris, stroke, and heart failure. RESULTS The median patient age was 54 years, and 37.5% of the patients were men. Metabolic syndrome was observed in 5558 (10.4%) patients. Over a mean follow-up period of 973 ± 791 days, 3085 composite CVD outcomes were recorded. Multivariable Cox regression analyses showed that metabolic syndrome was associated with a greater risk of developing CVD events (HR = 1.29, 95% CI = 1.15-1.45). Metabolic syndrome was also associated with an increased risk of CVD in patients with a follow-up period ≥1 year (HR = 1.33, 95% CI = 1.15-1.53). This relationship was also observed when metabolic syndrome was defined according to the International Diabetes Federation criteria (HR = 1.34, 95% CI = 1.21-1.49) and the National Cholesterol Education Program Adult Treatment Panel III criteria (HR = 1.32, 95% CI = 1.19-1.46). Subgroup analyses showed that the relationship between metabolic syndrome and incident CVD was more pronounced in the non-obese participants than in the obese participants. CONCLUSIONS Metabolic syndrome is associated with a greater risk of developing CVD, even among cancer survivors.

Abstract
CONTEXT Previous studies failed to adjust for estimated glomerular filtration rate (eGFR) in evaluating the association between albuminuria and anemia development, and we aimed to investigate whether albuminuria independently affects anemia development. METHODS We conducted a retrospective cohort study and retrospectively identified adults with diabetes from a Japanese nationwide clinical database (JMDC, Tokyo, Japan). To assess the modification effects of albuminuria on the association between eGFR and anemia development, we estimated prevalence of anemia, defined as hemoglobin < 13 g/dL in men and < 12 g/dL in women, using a modified Poisson regression and marginal standardization form of predictive margins, stratified by albuminuria severity after adjusting for eGFR. Hence, we revealed at which eGFR level this modification effect appeared and the extent to which this modification effect increased the prevalence of anemia. RESULTS We identified 327 999 data points from 48 056 individuals [normoalbuminuria: 186 472 (56.9%), microalbuminuria: 107 170 (32.7%), and macroalbuminuria: 34 357 (10.5%)]. As eGFR declined, anemia prevalence increased. Albuminuria severity modified this association induced by decreased eGFR among individuals with eGFR <30 mL/min/1.73 m2 after adjusting for multivariable factors, including age, sex, comorbidities, and medication use. Compared with the normoalbuminuric group, the macroalbuminuric group had a 5% to 20% higher anemia prevalence among individuals with eGFR of <30 mL/min/1.73 m2. CONCLUSION We revealed that the severity of albuminuria modified the association between eGFR and anemia development among individuals with eGFR <30 mL/min/1.73 m2, highlighting the modification effect of albuminuria on the association between kidney function and anemia development in diabetes.

Abstract
BACKGROUND There are few data on sex differences in the association between schizophrenia and the development of cardiovascular disease (CVD). We sought to clarify the relationship of schizophrenia with the risk of developing CVDs and to explore the potential modification effect of sex differences. METHODS AND RESULTS We conducted a retrospective analysis using the JMDC Claims Database between 2005 and 2022. The study population included 4 124 508 individuals aged 18 to 75 years without a history of CVD or renal replacement therapy. The primary end point is defined as a composite end point that includes myocardial infarction, angina pectoris, stroke, heart failure, atrial fibrillation, and pulmonary thromboembolism. During a mean follow-up of 1288±1001 days, we observed 182 158 composite end points. We found a significant relationship of schizophrenia with a greater risk of developing composite CVD events in both men and women, with a stronger association observed in women. The hazard ratio for the composite end point was 1.63 (95% CI, 1.52-1.74) in women and 1.42 (95% CI, 1.33-1.52) in men after multivariable adjustment (P for interaction=0.0049). This sex-specific difference in the association between schizophrenia and incident CVD was consistent for angina pectoris, heart failure, and atrial fibrillation. CONCLUSIONS Our analysis using a large-scale epidemiologic cohort demonstrated that the association between schizophrenia and subsequent CVD events was more pronounced in women than in men, suggesting the clinical importance of addressing schizophrenia and tailoring the CVD prevention strategy based on sex-specific factors.

Abstract
AIMS/INTRODUCTION We assessed the modification effect of adherence to diabetes care on the association between HbA1c levels and the risk of coronavirus disease 2019 (COVID-19) among individuals with diabetes using a population-based database. MATERIAL AND METHODS We retrospectively identified individuals with diabetes during routine health checkups performed in 2019 in Japan using a population-based claims database (JMDC, Tokyo, Japan). We assessed the risk of COVID-19 infection in 2020 in relation to HbA1c levels during routine checkups, stratified by the presence/absence of follow-up for diabetes care in 2019. Several sensitivity analyses were performed. RESULTS We identified 65,956 individuals with an HbA1c ≥6.5% and fasting glucose ≥126 mg/dL in routine checkups, including 52,637 and 13,319 with and without at least one physician consultation for diabetes care in 2019, respectively. Although high HbA1c levels were associated with an increased risk of COVID-19 infection in a dose-dependent manner among individuals without diabetes care in 2019 (odds ratios, 1.53 and 2.17 in individuals with HbA1c of 7.0-7.9% and ≥8.0%, respectively) with a reference to HbA1c of 6.5-6.9%, individuals with diabetes care had no such trend in 2019 (odds ratios, 0.99 and 0.97 among individuals with HbA1c of 7.0-7.9% and ≥8.0%, respectively). Sensitivity analyses yielded consistent results when the variable definitions were changed and after multivariable adjustment with multiple imputation. CONCLUSIONS This population-based study suggests that adherence to diabetes care may modify the association between HbA1c levels and the risk of COVID-19 infection.

Abstract
OBJECTIVE The optimal strategy for difficult-to-treat (D2T) rheumatoid arthritis (RA) has not been identified, and the ultrasound characteristics of D2T RA have not been reported. We investigated the clinical characteristics and factors contributing to the outcome in D2T RA in a multicentre RA ultrasound observational cohort. METHOD We reviewed 307 Japanese patients diagnosed with RA who underwent treatment with biological and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs). We compared the differences in patient characteristics between the D2T RA and non-D2T RA groups. We examined the factors contributing to a good response [defined as b/tsDMARD continuation and Clinical Disease Activity Index (CDAI) ≤ 10 at 12 months] in the D2T RA patient group. RESULTS Forty-three patients (14%) were categorized as D2T RA and the remaining 264 (86%) as non-D2T RA at baseline. The grey-scale (GS) score, disease duration, and CDAI at the initiation of treatment were significantly higher in the D2T RA group than in the non-D2T RA group. In contrast, the power Doppler (PD) score was not significantly different between the two groups. Of the 43 D2T RA patients, 20 achieved a good response. The introduction of CTLA4-Ig (n = 5) was significantly associated with a good response in analysis based on inverse probability weighting with propensity score. GS and PD scores at baseline were not significantly associated with therapeutic response at 12 months in D2T RA patients. CONCLUSIONS Patients with D2T RA had high clinical and ultrasound activity and poor responses to treatment with b/tsDMARDs. CTLA4-Ig was associated with a good response at 12 months in D2T RA patients.

Abstract
BACKGROUND Takotsubo syndrome (TTS) is a cardiac disorder that mimics acute coronary syndrome at presentation. While previous studies have demonstrated a relationship between body mass index (BMI) and outcomes in acute coronary syndrome, few have examined its relationship with TTS. METHODS Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified 14,551 patients admitted for TTS between 2010-2021. By applying multivariable regressions with restricted cubic splines, we examined the association between BMI and in-hospital mortality after adjusting for potential confounders. RESULTS Mean BMI was 21.1 kg/m2, classifying patients into severe underweight (<16.0 kg/m2, 7.1%), mild/moderate underweight (16.0-18.4 kg/m2, 18.3%), normal weight (18.5-22.9 kg/m2, 46.8%), overweight (23.0-27.4 kg/m2, 22.2%), and obese (≥27.5 kg/m2, 5.6%) groups. Patients with severe or mild/moderate underweight were older and had a higher prevalence of impaired physical activity, malignancy, chronic pulmonary disease, and pneumonia. In-hospital mortality was the highest (9.4%) in the severe underweight group, followed by the mild/moderate underweight group (5.4%), with the lowest being in the obese group (2.1%). Severe underweight (adjusted odds ratio=2.05 [95% CI=1.54-2.73]) and mild/moderate underweight (1.26 [1.01-1.57]) were significantly associated with higher mortality compared with normal weight, while no significant association was noted with obesity. A nonlinear association between continuous BMI and mortality was observed, with mortality increasing when BMI decreased <20.0 kg/m2 but nearly plateauing in BMI >20 kg/m2. CONCLUSIONS The present nationwide analysis demonstrated a nonlinear association between BMI and in-hospital mortality of TTS. BMI is an easily available and clinically relevant marker for the risk stratification of TTS.

Abstract
BACKGROUND Data regarding the relationship between benign prostatic hyperplasia (BPH) and incident cardiovascular disease (CVD) are scarce. We aimed to clarify the association of BPH with the risk of developing CVD using a nationwide epidemiological database.Methods and Results: This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2022, including 2,370,986 men (median age 44 years). The primary endpoints were myocardial infarction (MI), angina pectoris (AP), stroke, heart failure (HF), and atrial fibrillation (AF), which were assessed separately. BPH was observed in 48,651 (2.1%) men. During a mean (±SD) follow-up of 1,359±1,020 days, 7,638 MI, 52,167 AP, 25,355 stroke, 58,183 HF, and 16,693 AF events were detected. Hazard ratios of BPH for MI, AP, stroke, HF, and AF were 1.04 (95% confidence interval [CI] 0.92-1.18), 1.31 (95% CI 1.25-1.37), 1.26 (95% CI 1.18-1.33), 1.21 (95% CI 1.16-1.27), and 1.15 (95% CI 1.07-1.24), respectively. We confirmed the robustness of our primary findings through a multitude of sensitivity analyses. In particular, a history of BPH was associated with a higher risk of developing CVD, even in participants without obesity, hypertension, diabetes, or dyslipidemia. CONCLUSIONS Our analysis of a nationwide epidemiological dataset demonstrated that BPH was associated with a greater risk of developing CVD in middle-aged men.

Abstract
BACKGROUND Familial hypercholesterolemia (FH) is associated with atherosclerotic cardiovascular disease (ASCVD). However, the prevalence of FH among a general population remains unknown, and it is unclear if FH is associated with other cardiovascular complications, including heart failure (HF) and atrial fibrillation (AF). METHODS Analyses were conducted on individuals without a prior history of cardiovascular disease using a nationwide health claims database collected in the JMDC Claims Database between 2005 and 2022 (n = 4,126,642; median age, 44 years; 57.5% men). We defined FH as either LDL cholesterol ≥250 mg/dL or LDL cholesterol ≥175 mg/dL under the lipid-lowering medications under the assumption that lipid-lowering medications reduced LDL cholesterol by 30%. We assessed the associations between FH and composite outcomes, including, ASCVD (myocardial infarction, angina pectoris, and stroke), HF, and AF using Cox proportional hazard model. RESULTS We identified 11,983 (.29%) FH patients. In total, 181,150 events were recorded during the mean follow-up period of 3.5 years. The status FH was significantly associated with composite outcomes after adjustments (hazard ratio [HR]; 1.38, 95% confidence interval [CI]: 1.30-1.47, p < .001). Interestingly, the status FH was significantly associated with HF (HR: 1.48, 95% CI: 1.36-1.61, p < .001) and AF (HR: 1.33, 95% CI: 1.08-1.64, p < .001) in addition to angina pectoris (HR: 1.45, 95% CI: 1.33-1.58, p < .001) and stroke (HR: 1.19, 95% CI: 1.04-1.36, p < .001). CONCLUSION We found that the prevalence of FH was .29% in a general population. FH was significantly associated with a higher risk of developing cardiovascular disease, HF and AF. LAY SUMMARY We sought to identify the prevalence of FH among a general population, and to clarify whether FH increases the risk of not only ASCVD but also HF and AF.

Abstract
Introduction We sought to examine the association of cancer history with the incidence of individual cardiovascular disease events and to clarify whether the history of cancer modifies the relationship between conventional cardiovascular risk factors and incident cardiovascular disease. Methods This retrospective cohort study used the JMDC Claims Database, including 3,531,683 individuals. The primary endpoint was the composite cardiovascular disease outcome, which included myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. Results During a follow-up, 144,162 composite endpoints were recorded. Individuals with a history of cancer had a higher risk of developing composite cardiovascular disease events (HR 1.26, 95% CI 1.22-1.29). The HRs for myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation were 1.11 (95% CI 0.98-1.27), 1.15 (95% CI 1.10-1.20), 1.11 (95% CI 1.05-1.18), 1.39 (95% CI 1.34-1.44), and 1.22 (95% CI 1.13-1.32), respectively. Individuals who required chemotherapy for cancer had a higher risk of developing cardiovascular disease. Although conventional risk factors (e.g., overweight/obesity, hypertension, and diabetes) were associated with incident composite cardiovascular disease even in individuals with a history of cancer, the total population-attributable fractions of conventional risk factors were less in individuals with a history of cancer. Conclusion Individuals with a history of cancer (particularly those requiring chemotherapy) have a higher risk of cardiovascular disease. Traditional risk factors are important in the development of cardiovascular disease in individuals with and without a history of cancer. In individuals with a history of cancer, however, the total population-attributable fractions of conventional risk factors decreased.

Abstract
Introduction Preventive programs, including screenings for cancer and diabetes, were disrupted globally due to the coronavirus disease 2019 (COVID-19) pandemic in 2020. We previously conducted a nationwide survey to investigate the initial impact of the pandemic on health check-ups; however, the impact in the second and third years of the pandemic has not yet been elucidated. Here, we conducted a follow-up survey targeting healthcare facilities to evaluate the impact of the pandemic until the end of 2022. Methods A questionnaire survey was conducted between December 15, 2022, and February 10, 2023, targeting member facilities of Japan Society of Ningen Dock. The survey consisted of two parts. Part I comprised a web-based questionnaire, in which the facilities were asked about their commitment to COVID-19-related care, precautions against COVID-19, and whether the pandemic had a negative financial impact on the management of health check-ups. In Part II, the facilities were asked about the number of examinees who underwent health check-ups between 2019 and 2022, the proportion of those who needed and adhered to follow-up visits, and the number of cancer cases found between 2019 and 2021. Results Of the 1,343 eligible facilities, 885 participated (response rate: 65.9%). The observation that the number of people undergoing mandatory check-ups increased while those undergoing nonmandatory check-ups (e.g., cancer screenings by local governments) decreased in 2021, compared with that of 2019, persisted into 2022. Approximately 60% of the facilities reported a negative financial impact on the management of health check-ups, even in 2022. Conclusions In 2022, the pandemic's detrimental effects on health check-ups persisted.

Abstract
AIMS Contemporary guidelines differ in their recommendations regarding initiating non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) at low risk of stroke. This study aimed to examine the effectiveness and safety of NOACs for low-risk AF in a Japanese cohort. METHODS AND RESULTS In this retrospective cohort study based on the JMDC Claims Database extracted between April 2011 and November 2022, we identified 13 291 patients with AF at low risk of stroke. We performed inverse probability of treatment weighting Cox regression analyses to compare the embolization and bleeding risks between the nontreatment and NOAC groups. Net clinical benefit was defined as the annual incidence of ischaemic stroke events prevented by NOACs after subtracting intracranial haemorrhage (ICH) events attributable to NOACs, multiplied by a weighting factor. The incidences of stroke and ICH in the nontreatment group were 0.47 and 0.15 per 100 person-years, respectively. The NOAC group had higher incidences of ICH (hazard ratio [HR]: 1.73, 95% confidence interval [CI]: 0.75-4.00) and stroke (HR: 1.41, 95% CI: 0.84-2.36). The net clinical benefit of NOAC treatment was -0.35% per year (95% CI: -0.99-0.29%). CONCLUSION Non-vitamin K antagonist oral anticoagulants treatment may be associated with a slightly high risk of ICH, and it yielded a neutral clinical benefit in the present Japanese population, which provides reassurance concerning the role of ethnicity in NOAC treatment for patients with AF and suggests a need to assess comprehensive weighting of the respective risk factors.

Abstract
BACKGROUND Despite the widespread practice of Japanese traditional Kampo medicine, the characteristics of patients receiving various Kampo formulations have not been documented in detail. We applied a machine learning model to a health insurance claims database to identify the factors associated with the use of Kampo formulations. METHODS A 10% sample of enrollees of the JMDC Claims Database in 2018 and 2019 was used to create the training and testing sets, respectively. Logistic regression analyses with lasso regularization were performed in the training set to construct models with prescriptions of 10 commonly used Kampo formulations in 1 year as the dependent variable and data of the preceding year as independent variables. Models were applied to the testing set to calculate the C-statistics. Additionally, the performance of simplified scores using 10 or 5 variables were evaluated. RESULTS There were 338,924 and 399,174 enrollees in the training and testing sets, respectively. The commonly prescribed Kampo formulations included kakkonto, bakumondoto, and shoseityuto. Based on the lasso models, the C-statistics ranged from 0.643 (maoto) to 0.888 (tokishakuyakusan). The models identified both the common determinants of different Kampo formulations and the specific characteristics associated with particular Kampo formulations. The simplified scores were slightly inferior to full models. CONCLUSION Lasso regression models showed good performance for explaining various Kampo prescriptions from claims data. The models identified the characteristics associated with Kampo formulation use.

Abstract
Background and hypothesis Proteinuria is associated with an increased risk of kidney function deterioration, cardiovascular disease, or cancer. Previous reports suggesting an association between kidney dysfunction and bone fracture may be confounded by concomitant proteinuria and were inconsistent regarding the association between proteinuria and bone fracture. Therefore, we aimed to evaluate the association using a large administrative claims database in Japan. Methods Using the DeSC database, we retrospectively identified individuals with laboratory data including urine dipstick test between August 2014 and February 2021. We evaluated the association between proteinuria and vertebral or hip fracture using multivariable Cox regression analyses adjusted for various background factors including kidney function. We also performed subgroup analyses stratified by sex and kidney function and sensitivity analyses with Fine & Gray models considering death as a competing risk. Results We identified 603 766 individuals and observed 21 195 fractures. With reference to the negative proteinuria group, the hazard ratio for hip or vertebral fracture was 1.10 [95% confidence interval (CI), 1.05-1.14] and 1.16 (95%CI, 1.11-1.22) in the trace and positive proteinuria group, respectively, in the Cox regression analysis. The subgroup analyses showed similar trends. The Fine & Gray model showed a subdistribution hazard ratio of 1.09 (95%CI, 1.05-1.14) in the trace proteinuria group and 1.15 (95% CI, 1.10-1.20) in the positive proteinuria group. Conclusions Proteinuria was associated with an increased risk of developing hip or vertebral fractures after adjustment for kidney function. Our results highlight the clinical importance of checking proteinuria for predicting bone fractures.

Abstract
BACKGROUND It remains unclear if remnant cholesterol is associated with atherosclerotic cardiovascular disease (ASCVD) (myocardial infarction, angina pectoris and stroke), heart failure (HF), and atrial fibrillation (AF) under primary prevention settings. OBJECTIVE We aimed to clarify this issue among a general population without a history of ASCVD, HF or AF. METHODS Analyses were conducted with a nationwide health claims database collected in the JMDC Claims Database between 2005 and 2022 (n = 1,313,722; median age, 42 years; 54.6% men). We assessed the associations between remnant cholesterol calculated as total cholesterol minus HDL cholesterol minus LDL cholesterol and composite CVD outcomes, including, ASCVD, HF, and AF using Cox proportional hazard model, dividing the individuals into tertiles of remnant cholesterol (T1-T3). RESULTS The mean follow-up duration was 3.0 years. In total, 43,755 events were recorded. Remnant cholesterol was significantly associated with composite CVD outcomes after adjustments (T3 vs T1: hazard ratio [HR]; 1.07, 95% confidence interval [CI]: 1.04-1.10, p-trend<0.001). Remnant cholesterol was associated with myocardial infarction (T3 vs T1:HR: 1.20, 95% CI: 1.06-1.34, p-trend=0.002), angina pectoris (T3 vs T1:HR: 1.09, 95% CI: 1.05-1.14, p-trend<0.001), stroke (T3 vs T1:HR: 1.08, 95% CI: 1.02-1.14, p-trend=0.007), and HF (T3 vs T1:HR: 1.08, 95% CI: 1.04-1.12, p-trend<0.001), while we found a marginal inverse association between remnant cholesterol and AF (T3 vs T1:HR: 0.92, 95% CI: 0.86-1.00, p-trend=0.054). CONCLUSION Remnant cholesterol was positively associated with ASCVD and HF, while we found a marginal inverse association between remnant cholesterol and AF.

Abstract
Background Metabolic dysfunction-associated fatty liver disease (MAFLD) is a novel concept of hepatic disease. Although the prevalences of heart failure (HF) and atrial fibrillation (AF) are increasing worldwide, limited data have assessed the extent to which MAFLD is associated with incident HF and AF. Objectives The authors sought to examine the association of MAFLD with incident HF and AF. Methods Analyses were conducted using a nationwide epidemiologic database including 3,279,918 individuals (median age 45 years; 57.6% men). Metabolic dysfunction was defined as 1 or more of the following: overweight (body mass index ≥23 kg/m2), metabolic syndrome, or diabetes mellitus. FLD was defined as fatty liver index of >30. MAFLD was defined as the coexistence of metabolic dysfunction and FLD. We categorized study participants into 4 groups: non-FLD/nonmetabolic dysfunction (n = 1,709,116), metabolic dysfunction (n = 584,483), FLD (n = 89,497), and MAFLD (n = 896,822). The primary outcomes were HF and AF. Results Over a mean follow-up period of 1,160 ± 905 days, 62,746 incident HF events and 15,408 incident AF events were recorded. Compared with the non-FLD/non-metabolic dysfunction group, HRs for HF and AF, respectively, were 1.20 (95% CI: 1.18-1.23) and 1.13 (95% CI: 1.08-1.19) for metabolic dysfunction, 1.24 (95% CI: 1.19-1.30) and 1.13 (95% CI: 1.04-1.23) for FLD, and 1.73 (95% CI: 1.69-1.76) and 1.51 (95% CI: 1.46-1.57) for MAFLD. MAFLD was also associated with a higher risk of developing myocardial infarction, angina pectoris, and stroke. A risk of developing cardiovascular events differed between MAFLD subtypes (Wald test P < 0.001). Conclusions MAFLD was associated with a greater risk of developing HF and AF, suggesting the clinical importance of this novel hepatic disease concept.

Abstract
CONTEXT There have been insufficient data on the threshold of body mass index (BMI) for developing diabetes mellitus (DM) and the relationship between change in BMI and the subsequent risk of DM. OBJECTIVE We sought to clarify the association of BMI and its change with incident DM. METHODS We conducted a retrospective observational cohort study using the JMDC Claims Database between 2005 and 2021. We included 3 400 303 individuals without a prior history of DM or usage of glucose-lowering medications. The median age was 44 years, and 57.5% were men. We categorized the study participants into 4 groups: underweight (BMI < 18.5 kg/m2), normal weight (BMI 18.5-24.9 kg/m2), overweight (BMI 25.0-29.9 kg/m2), and obese (BMI ≥ 30 kg/m2). According to the change in BMI from the initial health check-up to the health check-up 1 year after that, we divided the study participants into 3 groups: ≤-5.0%, -5.0% to +5.0%, and ≥+5.0%. RESULTS The risk of developing DM increased steeply after BMI exceeded approximately 20 to 21 kg/m2. Compared with participants with stable BMI (-5.0% to +5.0%), the relative risk for DM among those whose BMI had increased by 5.0% or more was 1.33 (95% CI 1.31-1.36). In contrast, the relative risk for DM among those whose BMI decreased by 5.0% or more was 0.82 (95% CI 0.80-0.84). Moreover, people classified as normal weight, overweight, and obese reduced the risk of developing DM when they reduced their BMI, whereas the risk of developing DM for people classified as underweight increased when they reduced their BMI. CONCLUSION Our findings offer novel insights into improving an optimal bodyweight management strategy to prevent the development of DM.

Abstract
BACKGROUND Anti-glomerular basement membrane (anti-GBM) disease is treated with immunosuppressive medications and plasma exchange. However, whether plasma exchange, in addition to pulse glucocorticoid therapy, would benefit patients with anti-GBM disease with dialysis-dependent kidney failure without diffuse alveolar hemorrhage remains unclear. METHODS Using the Japanese Diagnosis Procedure Combination database, we identified patients diagnosed with anti-GBM disease with dialysis-dependent kidney failure and without diffuse alveolar hemorrhage from July 2010 to March 2020. We compared in-hospital mortality within 10 days of hospitalization between patients who received therapeutic plasma exchange in addition to pulse glucocorticoid therapy and those who received pulse glucocorticoid therapy alone. Overlap weighting based on propensity score was performed to adjust for potential confounders. RESULTS We identified 207 eligible patients; 168 patients received therapeutic plasma exchange plus pulse glucocorticoid therapy, while 39 patients received pulse glucocorticoid therapy alone. The mean dose of therapeutic plasma exchange was 52.2 ml/kg/day of albumin and/or fresh frozen plasma. Therapeutic plasma exchange in addition to pulse glucocorticoid therapy was associated with a lower in-hospital mortality risk in the unweighted (10.7% versus 28.2%; risk difference, 17.5%; 95% confidence interval, 2.6-32.4%; P = 0.02) and weighted analyses (11.5% versus 28.4%; risk difference, 17.0%; 95% confidence interval, 1.5-32.5%; P = 0.03) than pulse glucocorticoid therapy alone. CONCLUSIONS This retrospective cohort study using a national database suggests that therapeutic plasma exchange may improve the in-hospital prognosis of anti-GBM disease with dialysis-dependent kidney failure and without diffuse alveolar hemorrhage.

Abstract
Background Perioperative discontinuation of oral anti-parkinsonian medication can negatively impact the prognosis of abdominal surgery in patients with Parkinson's disease. Although intravenous levodopa may be an alternative, its efficacy has not yet been investigated. Objectives To determine the efficacy of intravenous levodopa as an alternative to oral anti-Parkinsonian drugs during gastric or colorectal cancer surgery. Methods We identified patients with Parkinson's disease who underwent surgery for gastric or colorectal cancer between April 2010 and March 2020, using the Diagnosis Procedure Combination database, a nationwide inpatient database in Japan. Patients were divided into two groups: those who received intravenous levodopa during the perioperative period and those who did not. We compared in-hospital mortalities, major complications, and postoperative length of stay between the groups after adjusting for background characteristics with overlap weights based on propensity scores. Results We identified 648 patients who received intravenous levodopa and 1207 who did not receive levodopa during the perioperative period. In the adjusted cohort, the mean postoperative length of stay was 24.7 and 29.0 days (percent difference, -7.7%; 95% confidence interval, -13.1 to -1.5); in-hospital death was 3.2% and 3.3% (adjusted odds ratio, 0.95; 95% CI: 0.54-1.67); and incidence of major complications were 21.4% and 19.3% (adjusted odds ratio, 0.89; 95% confidence interval, 0.70-1.13) in those with and without intravenous levodopa, respectively. Conclusions Intravenous levodopa was associated with a shorter postoperative length of stay, but not with mortality or morbidity. Intravenous levodopa may improve perioperative care in patients with Parkinson's disease.

Abstract
Cardiac rehabilitation (CR) is a promising therapeutic option for chronic heart failure (HF). However, the extent to which early rehabilitation is beneficial for patients receiving critical care remains controversial. This study examined the association between the early initiation of CR and the short-term clinical outcomes of patients admitted to the intensive care unit (ICU) with acute HF. We used the Diagnosis Procedure Combination database, a nationwide inpatient database in Japan, and included patients with acute HF admitted to the ICU within 2 days after hospital admission. We defined the early initiation of CR as its initiation within 2 days of hospital admission. We performed an overlap weighting based on the propensity scores and inverse probability of treatment weighting analysis to compare the clinical outcomes between patients with and without early initiation of CR. Among 25,362 eligible patients, 3,582 (14.1%) received an early initiation of CR. Overlap weighting created well-balanced cohorts, which showed that the early initiation of CR was related to lower in-hospital mortality (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.68 to 0.96) and shorter hospital stay. The inverse probability of treatment weighting analysis also showed that in-hospital mortality was lower in the patients with the early initiation of CR (OR 0.80, 95% CI 0.67 to 0.96). The instrumental variable analysis also demonstrated the association of the early initiation of CR with lower in-hospital mortality (OR 0.64, 95% CI 0.44 to 0.93). In conclusion, early initiation of CR after hospital admission was associated with better short-term outcomes in patients with acute HF admitted to the ICU, suggesting the potential of the early administration of CR for acute HF requiring intensive care.

Abstract
BACKGROUND The association between health behaviors and the risk of developing hypertension and diabetes is not fully understood. We aimed to examine the association between four health behaviors involved in Life's Essential 8, the American Heart Association's key measures for improving and maintaining cardiovascular health, and the incidence of hypertension and diabetes. METHODS This observational cohort study used the JMDC Claims Database between 2005 and 2021, which is a health check-up and claims database. We analyzed 2,912,183 participants without a history of hypertension, diabetes, cardiovascular disease, or renal failure. Non-ideal health behaviors included smoking, slow gait speed, eating fast, and poor sleep quality. RESULTS During 1140 ± 877 days, 201,385 hypertension and 142,156 diabetes events were recorded. In a multivariable Cox regression analysis, the risk of hypertension and diabetes increased with an increasing number of non-ideal health behaviors. The hazard ratios (HRs) (95% confidence interval [CI]) per 1-point increase in non-ideal health behavior components for hypertension and diabetes were 1.11 (1.10-1.11) and 1.08 (1.08-1.09), respectively. Each health behavior was independently associated with the incidence of hypertension and diabetes. A 1-point improvement in health behaviors was associated with a lower risk of developing hypertension (HR 0.94, 95% CI 0.93-0.95) and diabetes (HR 0.95, 95% CI 0.94-0.96). CONCLUSION Factors that can be substituted for the four health behaviors involved in Life's Essential 8 can stratify the risk of hypertension and diabetes, and improving these health behaviors is useful in preventing hypertension and diabetes in general population.

Abstract
AIM/INTRODUCTION This study aimed to investigate the clinical utility of 3 Screen ICA ELISA in identifying immune-mediated type 1 diabetes in Japanese subjects. METHODS We compared the positivity of 3 Screen ICA were compared with autoantibodies against GAD, IA-2, and ZnT8 in 638 patients with type 1 diabetes and 159 healthy control subjects. RESULTS With a cut-off value of 20.0 index, 67.4% of acute-onset type 1 diabetic patients, 71.8% of slowly progressive type 1 diabetic (SPIDDM) patients, and none of the fulminant type 1 diabetic patients showed 3 Screen ICA levels above this threshold. The prevalence of 3 Screen ICA was 14.2% higher in acute-onset type 1 diabetes and 1.6% higher in SPIDDM than in GADA. 3 Screen ICA-positive cases were found in 4.8% of cases of individual autoantibody-negative acute-onset type 1 diabetes and 3.8% of SPIDDM, indicating improved diagnostic sensitivity with the 3 Screen ICA. Among individual autoantibody-negative patients, the sum of each autoantibody level was significantly lower in fulminant type 1 diabetes than in acute onset type 1 diabetes and in SPIDDM (P < 0.0001). Additionally, 84.2% of patients negative for individual autoantibodies but positive for 3 Screen ICA had a sum of individual autoantibody levels of ≥4.7 U/mL. Furthermore, 3 Screen ICA levels were significantly higher in patients with type 1 diabetes with other autoimmune diseases than in those without (P < 0.0001). CONCLUSION Our findings suggest that the 3 Screen ICA ELISA may be a valuable screening tool for Japanese patients with type 1 diabetes, potentially increasing the diagnostic sensitivity and accuracy beyond the existing GADA, IA-2A, and ZnT8A tests.

Abstract
PURPOSE Understanding the practice patterns and costs of glaucoma care in real-world clinical settings is important for optimizing medical expenses. However, glaucoma treatment trends and associated costs in Japan are unknown. We aimed to unveil glaucoma treatment trends and costs using a large administrative claims database in Japan. STUDY DESIGN Retrospective cohort study. METHODS We included patients diagnosed with glaucoma between April 2014 and March 2021 using the DeSC database. We calculated the frequencies and costs of antiglaucoma eyedrops, incisional or laser procedures, and ophthalmic examinations stratified by fiscal year and age. In the year-by-year analyses, the age distribution was standardized based on the 2020 distribution. RESULTS A total of 841,747 patient-years (429,051 patients) were included. The number of prescribed eyedrops significantly increased and the fixed-combination eyedrops proportion decreased with age. Trabeculectomy frequency decreased, and that of laser trabeculoplasty increased during the observation period. The frequencies of both incisional and laser procedures peaked in the 75-79 age group. In 2020, 16.1 bottles of eyedrops per patient-year were prescribed, and 15.9 incisional surgeries and 11.3 laser therapies were performed per 1000 patient-years. Intraocular pressure measurement and visual field testing were performed 6.5 times and 2.0 times per patient-year, respectively. The total direct cost of glaucoma treatment was 55,139 yen (US $399.5) per patient-year, of which medications accounted for 44.2%, ophthalmic examinations for 47.4%, and incisional or laser procedures for 8.4%. CONCLUSION These results may be useful for understanding glaucoma treatment trends and costs in Japan.

Abstract
AIMS We aimed to explore the association between short-term exposure to temperature variability (TV), and cardiovascular hospitalization stratified by the presence of comorbid diabetes. METHODS We collected data on nationwide hospitalization for cardiovascular diseases and daily weather conditions during 2011-2018 in Japan. TV was calculated as the standard deviation of daily minimum and maximum temperatures within 0-7 lag days. We applied a two-stage time-stratified case-crossover design to estimate the association between TV and cardiovascular hospitalization with and without comorbid diabetes, adjusting for temperature and relative humidity. Furthermore, specific cardiovascular disease causes, demographic characteristics, and seasons were used for stratification. RESULTS In 3,844,910 hospitalizations for cardiovascular disease, each 1 °C increase in TV was associated with a 0.44% (95% CI: 0.22%, 0.65%) increase in the risk of cardiovascular admission. We observed a 2.07% (95% CI: 1.16%, 2.99%) and 0.61% (95% CI: -0.02%, 1.23%) increase per 1 °C in risk of heart failure admission in individuals with and those without diabetes, respectively. The higher risk among individuals with diabetes was mostly consistent in the analyses stratified by age, sex, body mass index, smoking status, and season. CONCLUSION Comorbid diabetes may increase susceptibility to TV in relation to acute cardiovascular disease hospitalization.

Abstract
AIMS Isolated diastolic hypertension (IDH) is a largely underrated risk factor for cardiovascular disease (CVD). It is currently unclear whether a reduction in blood pressure (BP) is associated with CVD events among adults with IDH. We aimed to elucidate the relationship between BP reduction and incident CVD in individuals with IDH. METHODS AND RESULTS We retrospectively analysed the data of 71 297 individuals with IDH. Isolated diastolic hypertension was defined as systolic BP of < 140 mmHg and diastolic BP (DBP) of ≥90 mmHg (median age, 48 years; 83.1% men; median DBP, 92 mmHg). None of the participants took BP-lowering medications or had a history of CVD at baseline. Blood pressure was measured at baseline and 1-year follow-up, and participants were categorized into two groups based on DBP at 1 year (≥90 or < 90 mmHg). The primary outcome was a composite endpoint that included myocardial infarction, stroke, and all-cause death. Over a mean follow-up period of 1100 ± 859 days, 1317 composite CVD endpoints were recorded. Participants with DBP of < 90 mmHg at 1 year were at a lower risk of composite CVD events [hazard ratio (HR): 0.75, 95% confidence interval (CI): 0.67-0.83] than those with DBP of ≥90 mmHg at 1 year. A reduction in DBP per 5 mmHg during the 1-year follow-up was associated with a lower composite CVD event risk (HR: 0.92, 95% CI: 0.89-0.95). The results remained consistent across a multitude of sensitivity analyses. CONCLUSION Our analysis of a large-scale epidemiological dataset demonstrated a relationship of reduction in DBP with a reduced risk for CVD events in individuals with IDH.

Abstract
INTRODUCTION Health check-ups have been disrupted worldwide by the COVID-19 pandemic, especially at its beginning. In Japan, undergoing annual check-ups is mandatory for full-time employees of all ages, while those other than full-time employees are entitled to undergo nonmandatory cancer screenings and specific health check-ups. To evaluate the impact of the COVID-19 pandemic on health check-ups, we conducted a nationwide questionnaire survey targeting healthcare facilities. METHODS A questionnaire survey was conducted between December 10, 2021, and January 28, 2022. Healthcare facilities were eligible if they were members of Japan Society of Ningen Dock and could respond via email. The monthly and yearly numbers of examinees undergoing mandatory or nonmandatory check-ups in 2020 and 2021 were compared with those in 2019. The proportions of examinees requiring follow-up visits and adhering to follow-up visits were compared between 2020 and 2019. Precautions taken against COVID-19 were also investigated. RESULTS Of the 1,299 eligible facilities, 639 participated (response rate, 49.2%). Health check-up services were suspended in 484 (75.7%) facilities for a median duration of 5 (interquartile range [IQR]: 4-8) weeks. A total of 19,861,230 and 21,748,125 examinees underwent health check-ups in 591 facilities in 2020 and 2021, respectively, 10.0% and 1.4% less than the numbers in 2019. The number of examinees undergoing health check-ups decreased by a median of 8.3% (IQR: -14.6 to -3.1) in 2020 compared to that in 2019, with the largest decrease of 70.3% (IQR -87.9 to -48.5) in May. Although the number of examinees undergoing mandatory check-ups increased in 2021 compared with that in 2019, the number of those undergoing nonmandatory check-ups remained low. CONCLUSIONS While people eligible for mandatory check-ups were adherent to check-ups in 2021, those ineligible for mandatory check-ups seemed less adherent. Public health efforts to encourage these people to adhere to check-ups during the pandemic are required.

Abstract
BACKGROUND The applicability of the Stages of Change model for cardiovascular disease-related behaviors, such as smoking, exercise, diet, and sleep quality, is unclear.Methods and Results: Using a large-scale epidemiological dataset, we found that baseline behavior change intention, as per the transtheoretical model, was associated with modifications of unhealthy lifestyles including cigarette smoking, physical inactivity, skipping breakfast, and poor sleep quality. CONCLUSIONS Our results suggest that an individual's motivation to change assessed by a general questionnaire may contribute to lifestyle modification and potentially prevent subsequent cardiovascular disease.

Abstract
BACKGROUND AND AIMS Although the importance of hypertension in patients with cancer is widely recognized, little is known about the risk of developing hypertension in patients with a history of cancer. METHODS This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2022, including 78,162 patients with a history of cancer and 3,692,654 individuals without cancer. The primary endpoint was the incidence of hypertension. RESULTS During a mean follow-up period of 1,208 ± 966 days, 311,197 participants developed hypertension. The incidence of hypertension was 364.6 (95% CI 357.0-372.2) per 10000 person-years among those with a history of cancer, and 247.2 (95% CI 246.3-248.1) per 10000 person-years in those without cancer. Individuals with a history of cancer had an elevated risk of developing hypertension according to multivariable Cox regression analyses (HR 1.17, 95% CI 1.15-1.20). Both cancer patients requiring active antineoplastic therapy (HR 2.01, 95% CI 1.85-2.20), and those who did not require active antineoplastic therapy (HR 1.14, 95% CI 1.12-1.17) had an increased risk of hypertension. A multitude of sensitivity analyses confirmed the robustness of the relationship between cancer and incident hypertension. Patients with certain types of cancer were found to have a higher risk of developing hypertension than those without cancer, with varying risks dependent on the type of cancer. CONCLUSIONS Our analysis of a nationwide epidemiological database revealed that individuals with a history of cancer have a higher risk of developing hypertension, and that this finding applies to both cancer patients who require active antineoplastic therapy and those who do not.

Abstract
BACKGROUND Data on the potential benefit of acute-phase rehabilitation initiation in very old (aged ≥90) patients with acute heart failure (AHF) have been scarce. METHODS We retrospectively analyzed data from the Diagnosis Procedure Combination database, which is a nationwide inpatient database. This study included patients hospitalized for heart failure (HF) from January 2010 to March 2018, those aged ≥90 years, who had a length of stay of ≥3 days, New York Heart Association (NYHA) class of ≥II, and had not undergone major procedures under general anesthesia. Propensity score matching and generalized linear models were used to compare in-hospital mortality, length of stay, 30-day readmission rate due to HF, all-cause 30-day readmission, and improvement in activities of daily living (ADL) between patients with and without an acute-phase rehabilitation initiation, which is defined as the rehabilitation initiation within 2 days after hospital admission. RESULTS Acute-phase rehabilitation was initiated in 8588 of 41,896 eligible patients. Propensity score matching created 8587 pairs. Patients with acute-phase rehabilitation initiation have lower in-hospital mortality (9.0% vs. 11.2%, p < 0.001). Acute-phase rehabilitation initiation was associated with lower in-hospital mortality (odds ratio, 0.778; 95% confidence interval, 0.704-0.860). Patients with acute-phase rehabilitation initiation have a shorter median length of stay (17 days vs. 18 days, p < 0.001), lower 30-day readmission rate due to HF (5.5% vs. 6.4%, p = 0.011) and all-cause 30-day readmission (10.2% vs. 11.2%, p = 0.036), and better ADL improvement (49.7% vs. 46.9%, p < 0.001). Subgroup analysis revealed consistent results (sex, body mass index, NYHA class, and Barthel Index). CONCLUSIONS The acute-phase rehabilitation initiation was associated with improved short-term clinical outcomes in patients aged ≥90 years with AHF.

Abstract
BACKGROUNDS/OBJECTIVES The threshold of hypertension was lowered from systolic blood pressure (SBP)/diastolic blood pressure (DBP) 140/90 mmHg to 130/80 mmHg by the 2017 American College of Cardiology/American Heart Association blood pressure (BP) guideline. Thus, we investigated the association between retinal vein occlusion (RVO) occurrence and early-stage hypertension. SUBJECTS/METHODS This retrospective cohort study used the JMDC Claims Database (JMDC Inc., Tokyo, Japan) between 2005 and 2020. Individuals undergoing health checkups who had data on BP and did not take antihypertensive medications were included. They were classified into four BP groups: normal BP (SBP < 120 mmHg and DBP < 80 mmHg), elevated BP (SBP 120-129 mmHg and DBP < 80 mmHg), stage 1 hypertension (SBP 130-139 mmHg or DBP 80-89 mmHg), and stage 2 hypertension (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg). Date of RVO occurrence was defined as the first date of diagnosis. We estimated adjusted hazard ratios for RVO and central RVO using weighted Cox regression to adjust for potential confounders. RESULTS A total of 2,703,264 individuals were eligible. During a mean follow-up of 1,091 days, 3,526 RVO and 828 central RVO events occurred. The adjusted hazard ratios (95% confidence intervals) were 1.37 (1.19-1.57), 1.95 (1.75-2.18), and 3.33 (2.95-3.76) for RVO and 1.44 (1.07-1.93), 2.17 (1.72-2.73), and 3.76 (2.91-4.86) for central RVO in the elevated BP, stage 1 hypertension, and stage 2 hypertension groups, respectively, compared with the normal BP group. CONCLUSIONS Even individuals with early-stage hypertension showed higher risks for RVO and central RVO than individuals with normal BP.

Abstract
BACKGROUND Substantial evidence suggests that non-optimal temperatures can increase the risk of cardiovascular disease (CVD) mortality and morbidity; however, limited studies have reported inconsistent results for hospital admissions depending on study locations, which also lack national-level investigations on cause-specific CVDs. METHODS We performed a two-stage meta-regression analysis to examine the short-term associations between temperature and acute CVD hospital admissions by specific categories [i.e., ischemic heart disease (IHD), heart failure (HF), and stroke] in 47 prefectures of Japan from 2011 to 2018. First, we estimated the prefecture-specific associations using a time-stratified case-crossover design with a distributed lag nonlinear model. We then used a multivariate meta-regression model to obtain national average associations. RESULTS During the study period, a total of 4,611,984 CVD admissions were reported. We found cold temperatures significantly increased the risk of total CVD admissions and cause-specific categories. Compared with the minimum hospitalization temperature (MHT) at the 98th percentile of temperature (29.9 °C), the cumulative relative risks (RRs) for cold (5th percentile, 1.7 °C) and heat (99th percentile, 30.5 °C) on total CVD were 1.226 [95% confidence interval (CI): 1.195, 1.258] and 1.000 (95% CI: 0.998, 1.002), respectively. The RR for cold on HF [RR = 1.571 (95% CI: 1.487, 1.660)] was higher than those of IHD [RR = 1.119 (95% CI: 1.040, 1.204)] and stroke [RR = 1.107 (95% CI: 1.062, 1.155)], comparing to their cause-specific MHTs. We also observed that extreme heat increased the risk of HF with RR of 1.030 (95% CI: 1.007, 1.054). Subgroup analysis showed that the age group ≥85 years was more vulnerable to these non-optimal temperature risks. CONCLUSIONS This study indicated that cold and heat exposure could increase the risk of hospital admissions for CVD, varying depending on the cause-specific categories, which may provide new evidence to reduce the burden of CVD.

Abstract
A 73-year-old man was diagnosed with left lung cancer (cT3N0M0, stageⅡB). Left lower lobectomy and lymph node dissection by complete video-assisted thoracic surgery (VATS) was planned. At surgery, removal of the left lower lobe thorough intercostal space was difficult, and the dissection of the left 5th rib was required. After surgery, air leak appeared and reoperation was performed. At second surgery, lung injuries caused by a cut edge of the left 5th rib were found. Both lung injuries and the dissected rib were repaired, and the postoperative course was uneventful.

Abstract
We sought to clarify the incidence of major adverse cardiac events (MACE) after the initiation of immune checkpoint inhibitors (ICIs). We analyzed the JMDC Claims Database between 2005 and 2021. The study included 2972 patients with no history of cardiovascular disease and a prescription for an ICI. The primary outcome was the incidence of MACE, including myocarditis, pericarditis, Takotsubo cardiomyopathy, atrio-ventricular block, heart failure, myocardial infarction, and stroke. The median age of study participants was 59 (Q1-Q3 53-65) years, and 2163 participants (72.8%) were male. Lung cancer was the most common cancer site (n = 1603). Among ICIs, programmed cell death-1 (PD-1) was most frequently used, and a combination ICI treatment was conducted in 110 patients (3.7%). During a mean follow-up of 358 ± 327 days, 419 MACE events were recorded. The incidence rate of myocarditis, pericarditis, Takotsubo cardiomyopathy, atrio-ventricular block, heart failure, myocardial infarction, and stroke was 3.4, 142.3, 10.3, 17.2, 1191.2, 55.2, and 278.5 per 10,000 person-years, respectively. The incidence of cardiovascular events was higher within 180 days after the initial prescription of ICI. The continuation rate of ICI after MACE was 38.4%. In conclusion, our analysis of a nationwide epidemiological dataset demonstrated the incidence of MACE after the initiation of ICI treatment. The incidence of heart failure was higher than expected, and the continuation rate of ICI treatment after MACE was low. Our results indicated the importance of monitoring and prevention of cardiovascular events in cancer patients requiring ICI treatment.

Abstract
OBJECTIVE To describe and compare the postoperative adverse events and re-treatment for recurrence after laparoscopic and robotic-assisted sacrocolpopexy in Japanese patients with pelvic organ prolapse (POP). METHODS This was a retrospective cohort study using the DeSC database, which contains claims and medical check-up data provided by DeSC Healthcare Inc., Tokyo, Japan. We identified all patients who had undergone either laparoscopic or robotic-assisted sacrocolpopexy from April 2014 to May 2021. Patient backgrounds and postoperative outcomes were compared between the laparoscopic and robotic-assisted sacrocolpopexy groups. Moreover, the composite adverse event comprising vaginal erosion, postoperative urinary incontinence, postoperative dysuria, urinary tract injury, and abdominal incisional hernia was evaluated. Re-treatment for POP recurrence included pessary use and surgery for POP was also evaluated. RESULTS Among 28 748 patients diagnosed with POP, 409 (1.4%) had undergone laparoscopic sacrocolpopexy and 52 (0.2%) had undergone robotic-assisted sacrocolpopexy. The prevalence of postoperative adverse events was 20.8% and 13.5% in the laparoscopic and robotic-assisted sacrocolpopexy groups, respectively (P = 0.270). One patient (1.9%) underwent surgery after robotic-assisted sacrocolpopexy, and none of the patients was administered pessaries postoperatively in both groups. CONCLUSION In Japan, postoperative outcomes after laparoscopic and robotic-assisted sacrocolpopexy are similar and comparable to those reported in western countries.

Abstract
BACKGROUND Anti-HER2 monoclonal antibody is associated with a greater risk of heart failure (HF) in female breast cancer patients. In recent years, the indication of anti-HER2 monoclonal antibodies was further expanded to stomach, colorectal, and salivary gland cancers regardless of sex in Japan. However, there have been no data on sex difference in the risk of HF after the anti-HER2 monoclonal antibody treatment. OBJECTIVES We compared the risk of HF between male and female cancer patients treated with anti-HER2 monoclonal antibody using a nationwide population-based database. METHOD We analyzed 4608 cancer patients (230 men, median age;52 years, breast cancer;4333) treated with HER2 monoclonal antibody enrolled in the JMDC Claims Database. The primary outcome was the incidence of HF. RESULTS Over a mean follow-up of 917±835 days, 559 HF events were documented. Kaplan-Meier curves showed no significant difference in the incidence of HF between men and women. Multivariable Cox regression analysis showed that male sex was not associated with a risk of HF compared with women (HR:0.76 95% CI:0.39-1.49). CONCLUSIONS Our analysis of a nationwide population-based database firstly revealed that no significant sex difference existed in the risk of HF among cancer patients treated with anti-HER2 monoclonal antibody. Our findings suggest that the use of anti-HER2 monoclonal antibodies in male patients may be associated with similar risks observed in female patients.

Abstract
Background Limited evidence is available on sex differences about the association between hypertension and incident atrial fibrillation (AF). Methods and Results We used a nationwide health checkup and claims database to analyze 3 383 738 adults (median age, 43 (36-51) years, 57.4% men). We investigated the relationship between hypertension and incident AF in men and women using a Cox regression model. We used restricted cubic spline functions to identify the association of blood pressure (BP) as a continuous parameter with incident AF. We categorized the men and women into 4 groups according to the 2017 American College of Cardiology/American Heart Association BP guidelines. During a mean follow-up of 1199±950 days, 13 263 AF diagnoses were recorded. The incidence (95% CI) of AF was 15.8 (15.5-16.1) per 10 000 person-years in men and 6.1 (5.9-6.3) per 10 000 person-years in women. Compared with normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension were associated with an increased risk AF in both men and women. However, the hazard ratios were greater in women than in men, and the P value for interactions in the multivariable model was 0.0076. The models using restricted cubic spline showed that the risk of AF associated with elevated systolic BP increased steeply above an approximate threshold of systolic BP of 130 mm Hg in men and 100 mm Hg in women. Although our primary findings were consistent across subgroup analyses, this association was most significant in younger individuals. Conclusions Although the incidence of AF was higher in men, the association between hypertension and incident AF was more pronounced in women than in men, suggesting a potential sex difference in the relationship between hypertension and incident AF.
