Control of Polar/Antipolar Layered Organic Semiconductors by the Odd-Even Effect of Alkyl Chain

Some rodlike organic molecules exhibit exceptionally high layered crystallinity when composed of a link between π-conjugated backbone (head) and alkyl chain (tail). These molecules are aligned side-by-side unidirectionally to form self-organized polar monomolecular layers, providing promising 2D materials and devices. However, their interlayer stacking arrangements have never been tunable, preventing the unidirectional arrangements of molecules in whole crystals. Here, it is demonstrated that polar/antipolar interlayer stacking can be systematically controlled by the alkyl carbon number n, when the molecules are designed to involve effectively weakened head-to-head affinity. They exhibit remarkable odd-even effect in the interlayer stacking: alternating head-to-head and tail-to-tail (antipolar) arrangement in odd-n crystals, and uniform head-to-tail (polar) arrangement in even-n crystals. The films show excellent field-effect transistor characteristics presenting unique polar/antipolar dependence and considerably improved subthreshold swing in the polar films. Additionally, the polar films present enhanced second-order nonlinear optical response along normal to the film plane. These findings are key for creating polarity-controlled optoelectronic materials and devices.

A machine-learning-based prediction of non-home discharge among acute heart failure patients

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.

Metabolic syndrome and cardiovascular disease in cancer survivors

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.

Association of Cancer and Its Interaction with Conventional Risk Factors on Cardiovascular Disease Risk

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.

Association of Metabolic Dysfunction-Associated Fatty Liver Disease With Risk of HF and AF

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.

Association of Body Mass Index and Its Change With Incident Diabetes Mellitus

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.

The estimation of coronary artery calcium thickness by computed tomography angiography based on optical coherence tomography measurements

Optical coherence tomography (OCT) is recommended to be the most appropriate modality in assessing calcium thickness, however, it has limitations associated with infrared attenuation. Although coronary computed tomography angiography (CCTA) detects calcification, it has low resolution and hence not recommended to measure the calcium size. The aim of this study was to devise a simple algorithm to estimate calcium thickness based on the CCTA image. A total of 68 patients who had CCTA for suspected coronary artery disease and subsequently went on to have OCT were included in the study. 238 lesions of them divided into derivation and validation dataset at 2:1 ratio (47 patients with 159 lesions and 21 with 79, respectively) were analyzed. A new method was developed to estimate calcium thickness from the maximum CT density within the calcification and compared with calcium thickness measured by OCT. Maximum Calcium density and measured calcium-border CT density had a good correlation with a linear equation of y = 0.58x + 201 (r = 0.892, 95% CI 0.855-0.919, p < 0.001). The estimated calcium thickness derived from this equation showed strong agreement with measured calcium thickness in validation and derivation dataset (r2 = 0.481 and 0.527, 95% CI 0.609-0.842 and 0.497-0.782, p < 0.001 in both, respectively), more accurate than the estimation by full width at half maximum and inflection point method. In conclusion, this novel method provided the estimation of calcium thickness more accurately than conventional methods.

Association Between Early Initiation of Cardiac Rehabilitation and Short-Term Outcomes of Patients With Acute Heart Failure Admitted to the Intensive Care Unit

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.

Impact of Stent Expansion Index on Stent Failure After Left Main Stenting

Impact of the stent expansion index (EXPI) in percutaneous coronary intervention (PCI) for unprotected left main distal bifurcation lesions (ULMD) has been not completely understood especially in current-generation drug-eluting stent (cDES) era. We evaluated the impact of EXPI on clinical outcomes after PCI with cDES for ULMD. We identified 342 patients treated with cDES for ULMD and postintervention intravascular ultrasound between January 2010 and December 2019. In this study, the ratio of minimum stent area (MSA) to reference vessel area at the MSA site was adopted to assess the stent expansion. We defined the patients with the first and second tertile as low-intermediate EXPI group and those with the third tertile as high EXPI group and compared the clinical outcomes between both groups. The primary end point was target lesion failure (TLF). TLF was defined as a composite of cardiac death, target lesion revascularization (TLR) ,and myocardial infarction. The MSA was located in the ostium of left anterior descending coronary artery in most cases (318 of 342 patients; 93.0%). There were no significant differences between both groups in the baseline clinical, lesion, and procedural characteristics. The high EXPI group had lower TLF rate than the low-intermediate EXPI group (10.2% vs 19.9%, log-rank p = 0.033). In conclusion, this is the first report that the higher ratio of MSA to reference vessel area at the MSA site, which was defined as stent EXPI, was associated with more favorable clinical outcomes after PCI for ULMD.

Malnutrition and inflammation status in nonobese patients with inflammatory bowel disease are associated with nonalcoholic fatty liver disease: a retrospective study

BACKGROUND/AIMS

The frequency and details of nonalcoholic fatty liver disease (NAFLD) complications in patients with inflammatory bowel disease (IBD) remain unclear. This study aimed to clarify characteristics of NAFLD in patients with IBD.

METHODS

We retrospectively identified and enrolled patients with IBD diagnosed with or without NAFLD by undergoing abdominal computed tomography (CT) at our institution between 2005 and 2020. The primary endpoint was the complication rate of NAFLD in patients with IBD. Secondary endpoints were the clinical characteristics of nonobese patients with IBD and comorbid NAFLD and their association with nutritional and inflammatory parameters.

RESULTS

Twenty-one (21.9%) of 96 eligible patients with IBD also had NAFLD. In nonobese patients (defined as patients with a body mass index <25 kg/m2), C-reactive protein (CRP; P<0.001) and alanine aminotransferase (P=0.018) levels were higher and the albumin level (P=0.005) and prognostic nutritional index (PNI; P=0.002) values were lower in patients with NAFLD than in those without NAFLD. The PNI value was positively correlated (P<0.001) and the CRP level was negatively correlated (P=0.001) with the hepatosplenic ratio. However, in the NAFLD combined group, PNI (P<0.05) and CRP values (P<0.001) were improved over time after CT imaging by continuing IBD treatment.

CONCLUSIONS

Worsening nutritional and inflammatory status in IBD patients is associated with complications of NAFLD. Diagnosis of NAFLD in IBD patients using CT imaging might be useful not only for early detection of NAFLD but also in assessing the need for therapeutic intervention for IBD.

Association of four health behaviors in Life's Essential 8 with the incidence of hypertension and diabetes mellitus

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.

Efficacy of azilsartan on left ventricular diastolic dysfunction compared with candesartan: J-TASTE randomized controlled trial

Characterized by ventricular and vascular stiffness, heart failure with preserved ejection fraction (HFpEF) has led to high morbidity and mortality. As azilsartan is an angiotensin receptor blocker with the highest myocardial and vascular affinities, azilsartan may improve the left ventricular (LV) diastolic function in patients with hypertension and either HFpEF or HF with mildly reduced ejection fraction (HFmrEF) more than candesartan. In this randomized, open-label trial, we randomly assigned 193 hypertensive patients with HF and LV ejection fraction ≥ 45% to 20 mg of azilsartan (n = 95) or 8 mg of candesartan (n = 98), once daily for 48 weeks. After the initiation of treatment, changes in the doses of the study drugs were permitted based on the patient's conditions, including blood pressure (median dose at 48 weeks: azilsartan 20.0 mg/day, candesartan 8.0 mg/day). The primary endpoint was the baseline-adjusted change in the ratio of peak early diastolic transmitral flow velocity (E) to early diastolic mitral annular velocity (e') (E/e'). Adjusted least-squares mean (LSM) change in E/e' was - 0.8 (95% confidence interval [CI] - 1.49 to - 0.04) in the azilsartan group and 0.2 (95% CI - 0.49 to 0.94) in the candesartan group, providing the LSM differences of - 1.0 (95% CI - 2.01 to 0.03, P = 0.057). The median change in left atrial volume index was - 2.7 mL/m2 with azilsartan vs 1.4 mL/m2 with candesartan (P = 0.091). The frequency of adverse events related to hypotension and hyperkalemia did not differ between the groups. The current study did not provide strong evidence that azilsartan improves LV diastolic dysfunction, and further confirmatory study is required.

Reduction in blood pressure for people with isolated diastolic hypertension and cardiovascular outcomes

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.

Association of early acute-phase rehabilitation initiation on outcomes among patients aged ≥90 years with acute heart failure

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.

Sex Differences in the Association Between Hypertension and Incident Atrial Fibrillation

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.

Blood Pressure Classification Using the 2017 ACC/AHA Guideline and Heart Failure in Patients With Cancer

PURPOSE

Despite the growing recognition of the importance of hypertension in patients with cancer, little is known about whether high blood pressure (BP) among patients with cancer is associated with incident heart failure (HF) and other cardiovascular disease (CVD) events and what BP levels are linked to these events. We examined the association of BP classification on the basis of the 2017 American College of Cardiology/American Heart Association BP guideline with the risk of HF and CVD events in patients with cancer.

METHODS

We studied 33,991 patients with a history of breast, colorectal, or stomach cancer (median age, 53 years; 34.1% men). Patients receiving treatment with BP-lowering medications or having a history of CVD including HF were excluded. Using BP measurements at baseline, 33,991 participants were categorized as having normal BP (n = 17,444), elevated BP (n = 4,733), stage 1 hypertension (n = 7,502), or stage 2 hypertension (n = 4,312). The primary outcome was HF.

RESULTS

Over a mean follow-up of 2.6 ± 2.2 years, 779 HF events were recorded. After multivariable adjustment, the hazard ratios (HRs) for HF were 1.15 (95% CI, 0.93 to 1.44) for elevated BP, 1.24 (95% CI, 1.03 to 1.49) for stage 1 hypertension, and 1.99 (95% CI, 1.63 to 2.43) for stage 2 hypertension. A stepwise increase in risk with BP categories was also observed in other CVD events. This association was observed even in patients undergoing active cancer treatment. The relationship between hypertension and the risk of developing HF in patients with cancer was confirmed in the Korean National Health Insurance Service database.

CONCLUSION

Medication-naïve stage 1 and 2 hypertension was associated with a greater risk of HF and other CVD events in patients with cancer. Our results suggest the importance of multidisciplinary collaboration (eg, oncologists and cardiologists) to establish the optimal management strategy for hypertension in patients with cancer.

Gait Speed and Cardiovascular Disease by Glycemic Status

INTRODUCTION

The aim of this study was to clarify whether the association of gait speed with the incidence of cardiovascular disease depends on baseline glycemic status.

METHODS

This retrospective observational cohort study used the Japan Medical Data Center Claims Database between 2005 and 2021 and analyzed 3,090,048 participants without a cardiovascular disease history. The median (IQR) age was 44 (37-53) years, and 1,755,205 of the participants (56.8%) were men. Information on gait speed was obtained from self-reported questionnaires in health checkups. Study participants were categorized according to HbA1c levels (<5.7%, 5.7-6.4%, and ≥6.5%). The primary endpoint was defined as a composite cardiovascular disease outcome that consists of heart failure, myocardial infarction, angina pectoris, and stroke.

RESULTS

During the mean follow-up period of 1,120±857 days, 116,678 composite cardiovascular disease outcomes were documented. Self-reported fast gait speed was related to a lower risk of developing cardiovascular disease; this relationship was more pronounced with increasing HbA1c levels. Compared with slow gait speed, the hazard ratio (95% CI) of self-reported fast gait speed for cardiovascular disease was 0.935 (0.921-0.949) in participants with an HbA1c <5.7%, 0.911 (0.891-0.932) in participants with an HbA1c of 5.7-6.4%, and 0.846 (0.811-0.883) in participants with HbA1c ≥6.5% (p-value for interaction<0.001).

CONCLUSIONS

The relationship of subjective gait speed with the risk of cardiovascular disease was amplified in individuals with prediabetes or diabetes mellitus, suggesting that maintaining exercise capacity could be more important in individuals with impaired glucose tolerance for preventing cardiovascular disease.

High-density lipoprotein cholesterol and clinical outcomes in diabetes mellitus

AIMS

High-density lipoprotein-cholesterol (HDL-C) has been thought to protect against cardiovascular disease (CVD), whereas a U-shaped association of both low and extremely high HDL-C with a high mortality risk has been increasingly reported in recent years. However, whether this U-shaped association is universal regardless of the individual's clinical background, including lifestyle diseases, remains unclear. We examined whether fasting plasma glucose modifies the U-shaped association between HDL-C level and clinical outcomes.

METHODS AND RESULTS

This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2021 for 3,282,389 participants without a history of CVD. The median age was 44 years (IQR, 36-51), and 1,878,164 participants (57.2%) were men. The median HDL-C level was 62 (IQR 52-74) mg/dL. The study participants were categorized according to fasting plasma glucose (FPG) levels (<100 mg/dL, 100-125 mg/dL, and ≥126 mg/dL). The primary endpoint was composite CVD outcome, consisting of myocardial infarction, stroke, and all-cause death. During a mean follow-up period of 1,181±932 days, 35,233 composite CVD events were recorded. The association between low HDL-C and CVD risk increased with FPG level, and the relationship of high HDL-C with CV outcome was prominent only in people with diabetes mellitus. A similar relationship was observed in the individual subgroups and in each CV outcome.

CONCLUSION

The U-shaped association between HDL-C and clinical outcomes was amplified with worsening glucose tolerance, suggesting a potential interaction between HDL-C levels and glycemic status on clinical outcomes.

Association of weight change and in-hospital mortality in patients with repeated hospitalization for heart failure

BACKGROUND

Although weight loss in heart failure (HF) is a detrimental condition known as cachexia, weight gain caused by fluid retention should also be considered harmful. However, studies with sufficient number of patients examining the impact of weight change and its interval on in-hospital mortality in HF have not been conducted thus far. We sought to elucidate the association of weight change with in-hospital mortality in patients with HF.

METHODS

This retrospective observational study used data from the Diagnosis Procedure Combination database, a nationwide inpatient health claims database in Japan. In total, 48 234 patients repeatedly hospitalized for HF (median 82 [74-87] years; 46.4% men) between 2010 and 2018 were included. Weight change was derived from body weight at the first and second admissions.

RESULTS

The median weight change and interval between two hospitalizations were -3.1 [-8.3 to -1.8] % and 172 [67-420] days, with 66.9% of overall cohort experiencing any weight loss. As a result of multivariable-adjusted logistic regression analysis, weight loss <-5.0% and weight gain >+5.0% were associated with increased in-hospital mortality (adjusted odds ratio [OR] [95% confidence interval]: 1.46 [1.31-1.62], P < 0.001 and 1.23 [1.08-1.40], P = 0.002, respectively) whereas mild weight loss and gain of 2.0-5.0% were not (OR [95% confidence interval]: 0.96 [0.84-1.10], P = 0.57 and 1.07 [0.92-1.25], P = 0.37, respectively), in comparison with patients with a stable weight (fluctuating no more than -2.0% to +2.0%) used as a reference. Restrictive cubic spline models adjusted for multiple background factors illustrated that higher mortality in patients with weight loss was observed across all subgroups of the baseline body mass index (<18.5, 18.5-24.9 and ≥25.0 kg/m² ). In patients with short (<90 days) and middle (<180 days) intervals between the two hospitalizations, both weight loss and weight gain were associated with high mortality, whereas the association between weight gain and high mortality was attenuated in those with longer intervals.

CONCLUSIONS

Both weight loss and weight gain in patients with repeated hospitalization for HF were associated with high in-hospital mortality, especially weight loss and short/middle-term weight gain. Such patients should be treated with caution in a setting of repeated hospitalization for HF.

The association of BP with cardiovascular outcomes in patients with dipstick proteinuria and preserved kidney function

Little is known about the relationship between blood pressure (BP) and incident cardiovascular disease (CVD) in people with proteinuria and a preserved estimated glomerular filtration rate (eGFR). This study sought to investigate the association of BP with CVD risk in adults with proteinuria and preserved eGFR. We studied 188,837 individuals with proteinuria and preserved eGFR ≥60 mL/min/1.73 m². We categorized individuals who were not taking BP-lowering medications into four groups based on the 2017 American College of Cardiology/American Heart Association BP guideline and categorized those who were taking BP-lowering medications using the same BP ranges. The primary outcome was a composite CVD endpoint that included myocardial infarction, angina pectoris, stroke, and heart failure. Over a mean follow-up of 1,050 days, 7,039 CVD events were identified. Compared with normal BP, stage 1 hypertension (hazard ratio [HR]: 1.30, 95% confidence interval [95% CI]: 1.21-1.40) and stage 2 hypertension (HR: 2.17, 95% CI: 2.01-2.34) were associated with an increased risk for CVD events among medication-naïve individuals. Only stage 2 hypertension range (HR: 1.19, 95% CI: 1.02-1.38) was associated with an increased CVD event risk among people taking BP-lowering medications. Restricted cubic spline analysis showed that the risk of CVD events increased monotonically with BP at an SBP/DBP > 120/80 mmHg among medication-naïve individuals, but risk increased only at an SBP/DBP > 140/90 mmHg among individuals taking BP-lowering medications. In conclusion, among people with proteinuria and preserved eGFR, stage 1 and stage 2 hypertension were associated with a greater risk of CVD among medication-naïve individuals, whereas only stage 2 hypertension was associated with an increased CVD risk among those taking BP-lowering medications.

Subjective Gait Speed and Risk of Developing Cardiovascular Events in 56,589 Cancer Survivors

Despite having a higher risk of cardiovascular disease (CVD), there are currently limited data for stratifying CVD risk among cancer survivors. The purpose of this study was to uncover the relationship of subjective gait speed with incident CVD among cancer survivors.This retrospective observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2021 including 56,589 patients with a prior history of breast, colorectal, or stomach cancer but no history of CVD. Gait speed was evaluated using information from self-reported questionnaires collected during health checkups. The primary endpoint was composite CVD outcome, which included heart failure, myocardial infarction, angina pectoris, and stroke.The median (interquartile range) age was 54 (48-61) years, and 20,981 (37.1%) were male. Among them, 25,933 patients (45.8%) reported fast gait speed. During a mean follow-up period of 1002 ± 803 days, 3,221 composite CVD outcomes were recorded. In multivariate Cox regression analysis, slow gait speed was associated with a higher risk of developing CVD compared with fast gait speed (hazard ratio, 1.14, 95% confidence interval, 1.06-1.22). This association was consistent across a variety of sensitivity analyses.We demonstrated that subjective slow gait speed was associated with a greater risk of CVD development among cancer survivors. This suggests the potential value of gait speed assessment for the CVD risk stratification of cancer patients as well as the clinical importance of maintaining exercise capacity among patients living with cancer.

Giant bulk piezophotovoltaic effect in 3R-MoS2

Given its innate coupling with wavefunction geometry in solids and its potential to boost the solar energy conversion efficiency, the bulk photovoltaic effect (BPVE) has been of considerable interest in the past decade^1-14. Initially discovered and developed in ferroelectric oxide materials², the BPVE has now been explored in a wide range of emerging materials, such as Weyl semimetals^9,10, van der Waals nanomaterials^11,12,14, oxide superlattices¹⁵, halide perovskites¹⁶, organics¹⁷, bulk Rashba semiconductors¹⁸ and others. However, a feasible experimental approach to optimize the photovoltaic performance is lacking. Here we show that strain-induced polarization can significantly enhance the BPVE in non-centrosymmetric rhombohedral-type MoS₂ multilayer flakes (that is, 3R-MoS₂). This polarization-enhanced BPVE, termed the piezophotovoltaic effect, exhibits distinctive crystallographic orientation dependence, in that the enhancement mainly manifests in the armchair direction of the 3R-MoS₂ lattice while remaining largely intact in the zigzag direction. Moreover, the photocurrent increases by over two orders of magnitude when an in-plane tensile strain of ~0.2% is applied, rivalling that of state-of-the-art materials. This work unravels the potential of strain engineering in boosting the photovoltaic performance, which could potentially promote the exploration of novel photoelectric processes in strained two-dimensional layered materials and their van der Waals heterostructures.

Interaction of Blood Pressure and Glycemic Status in Developing Cardiovascular Disease: Analysis of a Nationwide Real-World Database

Background Hypertension and diabetes frequently coexist. However, little is known about the interaction between high blood pressure (BP) and hyperglycemia in the development of cardiovascular disease (CVD). Methods and Results We conducted an observational cohort study that included 3 336 363 patients (median age, 43 years old; men, 57.2%). People taking BP- or glucose-lowering medications or those with prior history of CVD were excluded. We defined stage 1 hypertension as having systolic BP of 130 to 139 mm Hg or diastolic BP of 80 to 89 mm Hg and stage 2 hypertension as having systolic BP of ≥140 mm Hg or diastolic BP of ≥90 mm Hg. We defined prediabetes as having fasting plasma glucose of 100 to 125 mg/dL and diabetes as having fasting plasma glucose of ≥126 mg/dL. Over a mean follow-up period of 1185 ± 942 days, 5665 myocardial infarction, 52 475 angina pectoris, 25 436 stroke, 54 508 heart failure, and 12 932 atrial fibrillation events occurred. The BP and fasting plasma glucose categories additively increased the risk of myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. However, the relative risk of stage 1 and stage 2 hypertension developing into CVD was attenuated with deteriorating glycemic status. Similarly, the relative risk of prediabetes and diabetes developing into CVD was attenuated with increasing BP. For example, the relative risk reduction of stage 2 hypertension for heart failure was 53.5% in individuals with normal fasting plasma glucose, 46.4% in those with prediabetes, and 37.2% in those with diabetes. The robustness of our findings was confirmed using a multitude of sensitivity analyses. Conclusions Although hypertension and hyperglycemia additively increase the risk of developing CVD, the relative contribution of hypertension to the development of CVD decreased with deteriorating glycemic status and that of hyperglycemia was attenuated with increasing BP. Our results indicate a potential interaction between hypertension and hyperglycemia in the development of CVD.

Association of Life's Simple 7 with incident cardiovascular disease in 53 974 patients with cancer

AIMS

Cancer survivors have a greater risk of cardiovascular disease (CVD). Although Life's Simple 7 is used for CVD risk stratification in a general population, its utility in cancer survivors remains unknown. We aimed to clarify the association of Life's Simple 7 with incident CVD among cancer survivors. Furthermore, we analyzed the relationship between the change in Life's Simple 7 and the subsequent CVD risk.

METHODS AND RESULTS

This retrospective observational study was conducted using the JMDC Claims Database, and we analyzed 53 974 patients with a prior history of breast, colorectal, or stomach cancer, which is a common cancer site in the Japanese population. The median age was 54 years, and 37.8% were men. We modified the original definition of Life's Simple 7 and identified the following ideal Life's Simple 7 cardiovascular health metrics: non-smoking, body mass index < 25 kg/m2, physical activity at goal, optimal dietary habits, untreated fasting plasma glucose < 100 mg/dL, untreated blood pressure < 120/80 mmHg, and untreated total cholesterol < 200 mg/dL. The primary endpoint was composite CVD outcome, including myocardial infarction, angina pectoris, stroke, and heart failure. Over a mean follow-up period of 975 ± 794 days, 3150 composite CVD outcomes were recorded. The risk of CVD events increased with a greater number of non-ideal Life's Simple 7. The hazard ratio per 1-point increase in non-ideal Life's Simple 7 was 1.15 [95% confidence interval (CI): 1.12-1.18). Furthermore, a 1-point increase in non-ideal Life's Simple 7 over 1 year was associated with subsequent CVD risk (hazard ratio: 1.12, 95% CI: 1.06-1.19).

CONCLUSION

Life's Simple 7 could be applicable for CVD risk stratification even among cancer survivors. Optimizing Life's Simple 7 may prevent the development of CVD in cancer survivors.

Dose-dependent relationship of blood pressure and glycaemic status with risk of aortic dissection and aneurysm

AIMS

Data on the dose-dependent association of blood pressure (BP) and fasting plasma glucose (FPG) level with the risk of aortic dissection (AD) and aortic aneurysm (AA) are limited.

METHODS AND RESULTS

This observational cohort study included 3 358 293 individuals registered in a health checkup and claims database in Japan [median age, 43 (36-51) years; 57.2% men]. Individuals using BP- or glucose-lowering medications or those with a history of cardiovascular disease were excluded. In a mean follow-up period of 1 199 ± 950 days, 1 095 and 2 177 cases of AD and AA, respectively, were recorded. Compared with normal/elevated BP, hazard ratios (HRs) of Stage 1 and Stage 2 hypertension were 1.89 [95% confidence interval (CI): 1.60-2.22] and 5.87 (95% CI: 5.03-6.84) for AD and 1.37 (95% CI: 1.23-1.52) and 2.17 (95% CI: 1.95-2.42) for AA, respectively. Compared with normal FPG level, HRs of prediabetes and diabetes were 0.82 (95% CI: 0.71-0.94) and 0.48 (95% CI: 0.33-0.71) for AD and 0.94 (95% CI: 0.85-1.03) and 0.61 (95% CI: 0.47-0.79) for AA, respectively. The cubic spline demonstrated that the risk of AD and AA increased with increasing BP but decreased with increasing FPG level. Contour plots using generalized additive models showed that higher systolic BP and lower FPG level were associated with an elevated risk of AD and AA.

CONCLUSIONS

Our analysis showed a dose-dependent increase in the risk of AD or AA associated with BP and a similar decrease associated with FPG, and also suggested a potential interaction between hypertension and hyperglycaemia in the development of AD and AA.

Association of cardiovascular health metrics with annual incidence of prediabetes or diabetes: Analysis of a nationwide real-world database

AIMS/INTRODUCTION

Little is known about the relationship between cardiovascular health (CVH) metrics and the risk of developing prediabetes or diabetes. We examined the association of CVH metrics with the annual risk of developing prediabetes or diabetes.

MATERIALS AND METHODS

We carried out this study including 403,857 participants aged 18-71 years with available data on fasting plasma glucose (FPG) data for five consecutive years and with normal FPG (<100 mg/dL) at the initial health checkup. We identified the following ideal CVH metrics: non-smoking, body mass index of <25 kg/m² , maintaining physical activity, taking breakfast, untreated blood pressure of <120/80 mmHg and untreated total cholesterol of <200 mg/dL. We defined the primary end-point as prediabetes (FPG 100-125 mg/dL) or diabetes (FPG ≥126 mg/dL or use of antihyperglycemic medications). We examined the relationship of CVH metrics with the annual incidence of prediabetes or diabetes. Additionally, we examined the association of 1-year changes in CVH metrics with the risk for prediabetes or diabetes.

RESULTS

The median age was 44 years, and 65.6% were men. An increasing number of non-ideal CVH metrics was associated with an elevated risk of prediabetes or diabetes. A non-ideal body mass index was most strongly associated with the risk of prediabetes or diabetes. The risk of developing prediabetes or diabetes rose as the number of non-ideal CVH metrics increased over 1 year.

CONCLUSIONS

CVH metrics could stratify the risk of the annual development of prediabetes or diabetes. The risk of developing prediabetes or diabetes might be reduced by improving CVH metrics.

Glycemic status and the association of change in blood pressure with incident cardiovascular disease

BACKGROUND

The clinical benefit of blood pressure (BP) reduction in individuals with diabetes has not been fully elucidated. We sought to identify the clinical impact of BP reduction on incident cardiovascular disease in people having diabetes and hypertension.

METHODS

We conducted a retrospective cohort study including 754,677 individuals (median age 47 years, 75.8 % men) with stage 1/stage 2 hypertension. Participants were categorized using fasting plasma glucose (FPG) at baseline as normal FPG (FPG < 100 mg/dL) (n = 517,372), prediabetes (FPG:100-125 mg/dL) (n = 197,836), or diabetes mellitus (FPG ≥126 mg/dL) (n = 39,469). The primary outcome was heart failure (HF), and the secondary outcomes included ischemic heart disease (IHD) including myocardial infarction and angina pectoris, and stroke.

RESULTS

Over a mean follow-up of 1111 ± 909 days, 18,429 HFs, 17,058 IHDs, and 8,795 strokes were recorded. Reduction in BP of< 120/80 mmHg at 1year was associated with a lower risk of developing HF (HR:0.77, 95% CI:0.72-0.82), IHD (HR:0.84, 95% CI:0.79-0.89), and stroke (HR:0.75, 95% CI:0.69-0.82) in individuals with normal FPG, whereas it was not associated with a risk of developing HF (HR:0.98, 95% CI:0.81-1.17) and stroke (HR:0.82, 95% CI:0.62-1.09) in those with DM. Interaction analyses showed that the influence of BP reduction on incident HF was attenuated with people with prediabetes or DM. A multitude of sensitivity analyses confirmed our results.

CONCLUSIONS

The association of BP reduction with the risk of developing HF was attenuated with deteriorating glucose tolerance. The optimal management strategy for hypertensive people with prediabetes or DM for the prevention of developing cardiovascular disease (particularly HF) is needed to be established.

The impact of chronic kidney disease severity on clinical outcomes after current generation drug-eluting stent implantation for left main distal bifurcation lesions: the Milan and New-Tokyo registry

Objectives. The impact of chronic kidney disease (CKD) on clinical outcomes after percutaneous coronary intervention (PCI) for unprotected left main distal bifurcation lesions (ULMD) is not fully understood in current generation drug eluting stent (cDES) era. We assessed clinical outcomes after PCI using cDES for ULMD according to CKD severity based on estimated glomerular filtration rate (eGFR). Design. We identified 720 consecutive patients who underwent PCI using cDES for ULMD at three high volume centers between January 2005 and December 2015. We divided those patients to the following five groups according to eGFR. Each group was defined as follows: no CKD (60 mL/min/1.73 m² ≤ eGFR), mild CKD (45 ≤ eGFR < 60 mL/min/1.73 m²), moderate CKD (30 ≤ eGFR < 45 mL/min/1.73 m²), severe CKD (15 ≤ eGFR < 30 mL/min/1.73 m²) and hemodialysis (HD). The primary endpoint was target lesion failure (TLF) at 3 years. TLF was defined as a composite of cardiac death, target lesion revascularization (TLR) and myocardial infarction (MI). Results. TLF occurred more frequently in severe CKD and HD group compared with other three groups. Conclusions. The patients who have severe CKD or are on HD, were extremely associated with worse clinical outcomes after PCI for ULMD even with cDES.

Resolution of Laryngeal Ulceration with Prednisolone Therapy in a Patient with Crohn's Disease

A 23-year-old man diagnosed with Crohn's disease (CD) was treated with infliximab. He developed new-onset sore throat and dysphagia during admission, and nasopharyngoscopy revealed epiglottic ulceration. Laryngeal ulceration was considered as an extraintestinal manifestation of CD owing to treatment failure with antibiotics and hydrocortisone. This strongly suggested that laryngeal ulceration was a complication of CD because of the rapid improvement in the symptoms and lesions after prednisolone administration. Furthermore, this treatment process demonstrated the superior anti-inflammatory effect of prednisolone over that of hydrocortisone and supported the assumption of inflammation related to CD.

Digital transformation of droplet/aerosol infection risk assessment realized on "Fugaku" for the fight against COVID-19

The fastest supercomputer in 2020, Fugaku, has not only achieved digital transformation of epidemiology in allowing end-to-end, detailed quantitative modeling of COVID-19 transmissions for the first time but also transformed the behavior of the entire Japanese public through its detailed analysis of transmission risks in multitudes of societal situations entailing heavy risks. A novel aerosol simulation methodology was synthesized out of a combination of a new CFD methods meeting industrial demands in the solver, CUBE (Jansson et al., 2019), which not only allowed the simulations to scale massively with high resolution required for micrometer virus-containing aerosol particles but also enabled extremely rapid time-to-solution due to its ability to generate the digital twins representing multitudes of societal situations in a matter of minutes, attaining true overall application high performance; such simulations have been running for the past 1.5°years on Fugaku, cumulatively consuming top supercomputer-class resources and the communicated by the media as well as becoming the basis for official public policies.

Threshold of BMI for the Development of Hypertension among Japanese Adults

BACKGROUND

The optimal value of BMI for the development of hypertension and the influence of BMI on the development of stage 1 or stage 2 hypertension remain unclear.

OBJECTIVES

We sought to identify the BMI threshold for the prevention of hypertension and how changes in BMI would influence the risk of developing hypertension.

METHODS

We analyzed 1,262,356 participants (median age: 43 y; 50.9% men) with normal blood pressure [BP; systolic BP (SBP) <120 mmHg and diastolic BP (DBP) <80 mmHg] or elevated BP (SBP: 120-129 mmHg and DBP <80 mmHg). The primary outcome was stage 1 (SBP 130-139 mmHg or DBP 80-89 mmHg) or stage 2 hypertension (SBP ≥140 mmHg or DBP ≥90 mmHg). We analyzed the relation between baseline BMI, change in BMI, and the risk of developing hypertension using generalized additive models with a smoothing spline.

RESULTS

During the median follow-up of 851 d, 341,212 cases of stage 1 hypertension and 70,968 cases of stage 2 hypertension were detected. The risk of developing stage 1 or stage 2 hypertension increased steeply after BMI (kg/m²) exceeded 20. The annual change in BMI was positively correlated with the risk of developing stage 1 or 2 hypertension. Contour mapping using generalized additive models demonstrated an additive increase in the risk of developing hypertension with higher baseline BMI and increases in BMI over 1 y. Body-weight gain increases the risk of developing hypertension even in underweight or normal-weight individuals based on the WHO classification.

CONCLUSIONS

In Japanese adults with normal or elevated BP, the risk of developing hypertension increased with BMI when baseline BMI was >20. Body-weight gain additively interacted with baseline BMI during hypertension development. Our results underscore the importance of maintaining body weight in preventing the development of hypertension.

Kidney outcomes in patients with diabetes mellitus did not differ between individual sodium-glucose cotransporter-2 inhibitors

Data comparing kidney outcomes between individual sodium-glucose cotransporter-2 (SGLT2) inhibitors are limited. Here, we aimed to compare the subsequent risk of developing kidney outcomes between individual inhibitors. This would be the first study to compare kidney outcomes of patients with diabetes mellitus who were newly treated with individual SGLT2 inhibitors using a large-scale real-world dataset. To do this, we analyzed results from 12,100 patients with diabetes mellitus who were taking different SGLT2 inhibitors (2,573 with empagliflozin; 2,214 with dapagliflozin; 2,100 with canagliflozin; and 5,213 with other such inhibitors). The primary outcome was the rate of estimated glomerular filtration rate (eGFR) decline as assessed using a linear mixed-effects model with an unstructured covariance. The median age of the patients was 53 years, and 84.4% of the patients were men. The median fasting plasma glucose and HbA1c levels were 147 (interquartile range 126-178) mg/dL and 7.5 (6.9-8.4)%, respectively. The median eGFR was 78 mL/min/1.73 m² (interquartile range 68-90). The mean follow-up period was 773 days. The annual eGFR slopes of empagliflozin, dapagliflozin, canagliflozin, and other SGLT2 inhibitors were -1.15 (95% confidence interval, -1.33 to -0.96), -1.14 (-1.32 to -0.96), -1.24 (-1.44 to -1.04), and -1.06 (-1.18 to -0.94) ml/min/1.73 m², respectively. No significant interaction was detected between the SGLT2 inhibitors and time using a linear mixed-effects model. A multitude of sensitivity analyses confirmed the robustness of our primary results. Thus, we found that there was no significant difference in the annual eGFR decline slopes between patients taking different SGLT2 inhibitors.

Biomarkers associated with coronary high-risk plaques

Vascular inflammation, lipid metabolism, and thrombogenicity play a key role not only in atherogenesis but also in the development of acute coronary syndromes. Biomarkers associated with coronary high-risk plaques defined according to intravascular imaging have not been systematically studied. A total of 69 patients with coronary artery disease who underwent both optical coherence tomography and intravascular ultrasound imaging, and who provided blood specimens were included. Comprehensive biomarkers for inflammation, lipid, and coagulation were analyzed. Composite models sought biomarker patterns associated with thin-cap fibroatheroma (TCFA) and "high-risk plaques" (TCFA and large plaque burden). Two different composite models were developed for TCFA, based on the finding that high sensitivity C-reactive protein (hsCRP), plasminogen activator inhibitor-1, fibrinogen, IL-6, homocysteine and amyloid A levels were elevated, and high-density lipoprotein cholesterol (HDL) and bile acid levels were decreased in these patients. Both composite models were highly accurate for detecting patients with TCFA (area under curve [AUC]: 0.883 in model-A and 0.875 in model-B, both p < 0.001). In addition, creatinine, hsCRP, fibrinogen, tumor necrosis factor-α, IL-6, homocysteine, amyloid A, HDL, prothrombin, and bile acid were useful for detecting patients with "high-risk plaques". Two composite models were highly accurate for detection of patients with "high-risk plaques" (AUC: 0.925 in model-A and 0.947 in model-B, both p < 0.001). Biomarkers useful for detection of patients with high-risk coronary plaques defined according to intravascular imaging have been identified. These biomarkers may be useful to risk stratify patients and to develop targeted therapy.Clinical Trial Registration https://www.umin.ac.jp/ctr/ , UMIN000041692. Biomarkers and high-risk plaques hsCRP, PAI-1, fibrinogen, IL-6, homocysteine, amyloid A, HDL, and bile acid were useful for detecting patients with TCFA. hsCRP, fibrinogen, IL-6, homocysteine, amyloid A, creatinine, TNFα, HDL, prothrombin, and bile acid were useful for detecting patients with "high-risk plaques" (plaque which has both TCFA and large plaque burden). White arrowhead denotes TCFA. Red and green dashed lines denote lumen area and external elastic membrane area, respectively.

Association of Cardiovascular Health Metrics With Risk of Transition to Hypertension in Non-Hypertensive Young Adults

BACKGROUND

The risk of developing hypertension in young adults and its relationship to modifiable lifestyle factors are unclear. We aimed to examine the association of cardiovascular health (CVH) metrics with the risk of hypertension.

METHODS

We analyzed 66,876 participants aged 20-39 years, with available blood pressure (BP) data for 5 consecutive years, who had normal or elevated BP at the initial health check-up, enrolled in the JMDC Claims Database. Ideal CVH metrics included nonsmoking, body mass index <25 kg/m2, physical activity at goal, optimal dietary habits, untreated fasting glucose <100 mg/dL, and untreated total cholesterol <200 mg/dL. The primary endpoint was defined as stage 1 or stage 2 hypertension. We defined normal BP, elevated BP, stage 1 hypertension, and stage 2 hypertension according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) BP guideline.

RESULTS

The median age was 35 years, and 62% were men. Number of non-ideal CVH metrics was associated with an increasing risk for the development of stage 1 and stage 2 hypertension. Non-ideal body mass index was most strongly associated with a risk for hypertension. This association was more pronounced in women. An annual increase in the number of non-ideal CVH metrics was associated with an elevated risk for the hypertension development.

CONCLUSIONS

CVH metrics can stratify the risk for hypertension in non-hypertensive adults aged 20-39 years. These findings have important public health implications for the screening and prevention of hypertension. Improving CVH metrics may prevent the risk of developing hypertension in young adults.

Reduction in blood pressure for elevated blood pressure/stage 1 hypertension according to the ACC/AHA guideline and cardiovascular outcomes

Aims

Few studies have examined the relationship of blood pressure (BP) change in adults with elevated BP or stage 1 hypertension according to the ACC/AHA guideline with cardiovascular outcomes. We sought to identify the effect of BP change among individuals with elevated BP or stage 1 hypertension on incident heart failure (HF) and other cardiovascular diseases (CVDs).

Methods and results

We conducted a retrospective cohort study including 616,483 individuals (median age 46 years, 73.7% men) with elevated BP or stage 1 hypertension based on the ACC/AHA BP guideline. Participants were categorized using BP classification at one-year as normal BP (n = 173,558), elevated BP/stage 1 hypertension (n = 367,454), or stage 2 hypertension (n = 75,471). The primary outcome was HF, and the secondary outcomes included (separately) myocardial infarction (MI), angina pectoris (AP), and stroke. Over a mean follow-up of 1,097 ± 908 days, 10,544 HFs, 1,317 MIs, 11,070 APs, and 5,198 strokes were recorded. Compared with elevated BP/stage 1 hypertension at one-year, normal BP at one-year was associated with a lower risk of developing HF (HR:0.89, 95% CI:0.85-0.94), whereas stage 2 hypertension at one-year was associated with an elevated risk of developing HF (HR:1.43, 95% CI:1.36-1.51). This association was also present in other cardiovascular outcomes including MI, AP, and stroke. The relationship was consistent in all subgroups stratified by age, sex, baseline BP category, and overweight/obesity.

Conclusion

A one-year decline in BP was associated with the lower risk of HF, MI, AP, and stroke, suggesting the importance of lowering BP in individuals with elevated BP or stage 1 hypertension according to the ACC/AHA guideline to prevent the risk of developing CVD.

Gut Microbiota and Coronary Plaque Characteristics

Background The relationship between gut microbiota and in vivo coronary plaque characteristics has not been reported. This study was conducted to investigate the relationship between gut microbiota and coronary plaque characteristics in patients with coronary artery disease. Methods and Results Patients who underwent both optical coherence tomography and intravascular ultrasound imaging and provided stool and blood specimens were included. The composition of gut microbiota was evaluated using 16S rRNA sequencing. A total of 55 patients were included. At the genus level, 2 bacteria were associated with the presence of thin-cap fibroatheroma, and 9 bacteria were associated with smaller fibrous cap thickness. Among them, some bacteria had significant associations with inflammatory/prothrombotic biomarkers. Dysgonomonas had a positive correlation with interleukin-6, Paraprevotella had a positive correlation with fibrinogen and negative correlation with high-density lipoprotein cholesterol, Succinatimonas had positive correlations with fibrinogen and homocysteine, and Bacillus had positive correlations with fibrinogen and high-sensitivity C-reactive protein. In addition, Paraprevotella, Succinatimonas, and Bacillus were also associated with greater plaque volume. Ten bacteria were associated with larger fibrous cap thickness. Some were associated with protective biomarker changes; Anaerostipes had negative correlations with trimethylamine N-oxide, tumor necrosis factor α, and interleukin-6, and Dielma had negative correlations with trimethylamine N-oxide, white blood cells, plasminogen activator inhibitor-1, and homocysteine, and a positive correlation with high-density lipoprotein cholesterol. Conclusions Bacteria that were associated with vulnerable coronary plaque phenotype and greater plaque burden were identified. These bacteria were also associated with elevated inflammatory or prothrombotic biomarkers. Registration URL: https://www.umin.ac.jp/ctr/; Unique identifier: UMIN000041692.

Age-Specific Relation of Cardiovascular Health Metrics With Incident Cardiovascular Disease

We examined the age-related differences in cardiovascular health (CVH) metrics for incident cardiovascular disease (CVD). Analyses were conducted using data from the JMDC Claims Database from 2005 to 2020 (n = 2,728,427; mean age 44.9 ± 11.0 years; 56.2% men). Participants were categorized on the basis of age: 20 to 49 years (n = 1,800,161), 50 to 59 years (n = 644,703), and 60 to 75 years (n = 283,563). Ideal CVH metrics included nonsmoking, body mass index <25 kg/m², physical activity at goal, not skipping breakfast, blood pressure <120/80 mm Hg, fasting plasma glucose <100 mg/dL, and total cholesterol <200 mg/dL. Over a mean follow-up of 1,194 ± 917 days, 5,988 myocardial infarction (MI), 53,409 angina pectoris, 26,530 stroke, and 52,712 heart failure (HF) events were recorded. Number of the nonideal CVH metrics was associated with incident MI, angina pectoris, stroke, and HF in all age categories. However, the association of the number of nonideal CVH metrics with incident CVD was modified by age categories and was more pronounced in participants aged 20 to 49 years. Similarly, the relative risk reduction at 1 year for each CVD event under the virtual condition that an individual with 2 nonideal CVH metrics has decreased them to zero, decreased with age. For example, relative risk reduction for MI was 0.51 in participants aged 20 to 49 years, 0.48 in those aged 50 to 59 years, and 0.40 in those aged 60 to 75 years. In conclusion, CVH metrics were more strongly associated with incident CVD including HF among younger individuals suggesting the importance of optimizing modifiable risk factors and lifestyles in young participants for the primary CVD prevention.

Medication-Naïve Blood Pressure and Incident Cancers: Analysis of 2 Nationwide Population-Based Databases

BACKGROUND

Results of preceding studies on the relationship between blood pressure (BP) and cancers have been confounded due to individuals taking antihypertensive medications or shared risk factors. We assessed whether medication-naïve high BP is a risk factor for incident cancers.

METHODS

This retrospective observational study included 1,388,331 individuals without a prior history of cancer and not taking antihypertensive medications enrolled in the JMDC Claims Database between 2005 and 2018. The primary outcome was 16 cancers.

RESULTS

The median [interquartile range] age was 45 [40-52] years and 56.2% were men. Mean systolic BP (SBP) and diastolic BP (DBP) were 117.7 ± 15.8 and 72.8 ± 11.6 mm Hg. Multivariate Cox regression analysis demonstrated that SBP per 1-SD was associated with a higher incidence of thyroid (hazard ratio [HR]: 1.09, 95% confidence interval [CI]: 1.03-1.16), esophageal (HR: 1.15, 95% CI: 1.07-1.24), colorectal (HR: 1.04, 95% CI: 1.01-1.07), liver (HR: 1.11, 95% CI: 1.03-1.20), and kidney (HR: 1.22, 95% CI: 1.14-1.31) cancers, but with a lower incidence of stomach cancer (HR: 0.94, 95% CI: 0.91-0.98). These associations remained significant after adjustment for multiple testing. DBP was associated with higher incidences of thyroid, esophageal, colorectal, kidney, and corpus uteri cancers, but with a lower incidence of stomach cancer. The associations between SBP and incidences of thyroid, esophageal, colorectal, liver, and kidney cancers were confirmed in the Korean National Health Insurance Service database.

CONCLUSIONS

Medication-naïve BP was associated with higher incidences of thyroid, esophageal, colorectal, liver, and kidney cancers. Uncovering the underlying mechanisms for our results may help identify novel therapeutic approach for hypertension and cancer.

Spatial and Functional Crosstalk between the Mitochondrial Na+-Ca2+ Exchanger NCLX and the Sarcoplasmic Reticulum Ca2+ Pump SERCA in Cardiomyocytes

The mitochondrial Na⁺-Ca²⁺ exchanger, NCLX, was reported to supply Ca²⁺ to sarcoplasmic reticulum (SR)/endoplasmic reticulum, thereby modulating various cellular functions such as the rhythmicity of cardiomyocytes, and cellular Ca²⁺ signaling upon antigen receptor stimulation and chemotaxis in B lymphocytes; however, there is little information on the spatial relationships of NCLX with SR Ca²⁺ handling proteins, and their physiological impact. Here we examined the issue, focusing on the interaction of NCLX with an SR Ca²⁺ pump SERCA in cardiomyocytes. A bimolecular fluorescence complementation assay using HEK293 cells revealed that the exogenously expressed NCLX was localized in close proximity to four exogenously expressed SERCA isoforms. Immunofluorescence analyses of isolated ventricular myocytes showed that the NCLX was localized to the edges of the mitochondria, forming a striped pattern. The co-localization coefficients in the super-resolution images were higher for NCLX–SERCA2, than for NCLX–ryanodine receptor and NCLX–Na⁺/K⁺ ATPase α-1 subunit, confirming the close localization of endogenous NCLX and SERCA2 in cardiomyocytes. The mathematical model implemented with the spatial and functional coupling of NCLX and SERCA well reproduced the NCLX inhibition-mediated modulations of SR Ca²⁺ reuptake in HL-1 cardiomyocytes. Taken together, these results indicated that NCLX and SERCA are spatially and functionally coupled in cardiomyocytes.

Prediabetes in Young Adults and Its Association With Cardiovascular Health Metrics in the Progression to Diabetes

CONTEXT

The natural history of young adults with prediabetes and its association with cardiovascular health (CVH) metrics in progression to diabetes remain unknown.

OBJECTIVE

We examined the association between CVH metrics and the annual incidence of diabetes in young adults with prediabetes.

METHODS

This observational cohort study used the JMDC Claims Database. We analyzed 18 908 participants aged 18 to 44 years, with available fasting plasma glucose (FPG) data for 5 consecutive years, and who had prediabetes (FPG 100-125 mg/dL) at the initial health checkup. The ideal CVH metrics were as follows: nonsmoking, body mass index (BMI) less than 25 kg/m2, physical activity at goal, optimal dietary habits, blood pressure less than 120/80 mm Hg, and total cholesterol less than 200 mg/dL. We analyzed the association between CVH metrics and the annual incidence of diabetes. We also examined the relationship between 1-year changes in CVH metrics and the subsequent risk of diabetes.

RESULTS

The incidence of diabetes was 3.3% at 1 year and 9.5% at 5 years after the initial health checkup. An increasing number of nonideal CVH metrics have been associated with an increased risk of diabetes. Nonideal BMI, smoking, blood pressure, and total cholesterol level were associated with an increased risk of diabetes. This association was observed both in men and women. A one-point increase in the number of nonideal CVH metric components was associated over 1 year with an increased risk of diabetes.

CONCLUSION

CVH metrics can stratify the risk of diabetes in young adults with prediabetes. Improving CVH metrics may reduce the risk of developing diabetes.

Relationship of normal-weight central obesity with the risk for heart failure and atrial fibrillation: analysis of a nationwide health check-up and claims database

Aims

There have been scarce data on the relationship of normal-weight central obesity (NWCO) with the subsequent risk for heart failure (HF) and atrial fibrillation (AF). Using a nationwide health check-up and administrative claims database, we sought to clarify whether NWCO would be associated with the incidence of HF and AF.

Methods and results

Medical records of 1 697 903 participants without prior history of cardiovascular disease (CVD) and normal-weight (body mass index of 18.5–23.0 kg/m²) were extracted from the JMDC Claims Database, which is a health check-up and claims database. We defined NWCO as normal-weight and CO (waist circumference ≥ 90 cm for men or ≥ 80 cm for women). The median age was 44.0 (37.0–52.0) years and 872 578 (51.4%) participants were men. Overall, 154 778 individuals (9.1%) had CO. The mean follow-up period was 3.3 ± 2.6 years. Participants with NWCO were older and more likely to be women than those without. HF and AF occurred in 26 936 (1.6%) and 6554 (0.4%) participants, respectively. People having NWCO were associated with a greater risk for HF [hazard ratio (HR): 1.072, 95% confidence interval (CI) 1.026–1.119] and AF (HR: 1.202, 95% CI: 1.083–1.333) compared with those having normal-weight without CO.

Conclusion

Our analysis of a nationwide health check-up and administrative claims database including ∼1.7 million participants without prevalent CVD history demonstrated the potential impact of NWCO on the risk for HF and AF, suggesting the importance of abdominal obesity in the developing HF and AF even in normal-weight individuals.

Recognition of pathogen-derived sphingolipids in Arabidopsis

In plants, many invading microbial pathogens are recognized by cell-surface pattern recognition receptors, which induce defense responses. Here, we show that the ceramide Phytophthora infestans-ceramide D (Pi-Cer D) from the plant pathogenic oomycete P. infestans triggers defense responses in Arabidopsis. Pi-Cer D is cleaved by an Arabidopsis apoplastic ceramidase, NEUTRAL CERAMIDASE 2 (NCER2), and the resulting 9-methyl-branched sphingoid base is recognized by a plasma membrane lectin receptor-like kinase, RESISTANT TO DFPM-INHIBITION OF ABSCISIC ACID SIGNALING 2 (RDA2). 9-Methyl-branched sphingoid base is specific to microbes and induces plant immune responses by physically interacting with RDA2. Loss of RDA2 or NCER2 function compromised Arabidopsis resistance against an oomycete pathogen. Thus, we elucidated the recognition mechanisms of pathogen-derived lipid molecules in plants.

Comparison of cardiovascular outcomes between SGLT2 inhibitors in diabetes mellitus

Background

There have been scarce data comparing cardiovascular outcomes between individual sodium-glucose cotransporter-2 (SGLT2) inhibitors. We aimed to compare the subsequent cardiovascular risk between individual SGLT2 inhibitors.

Methods

We analyzed 25,315 patients with diabetes mellitus (DM) newly taking SGLT2 inhibitors (empagliflozin: 5302, dapagliflozin: 4681, canagliflozin: 4411, other SGLT2 inhibitors: 10,921). We compared the risks of developing heart failure (HF), myocardial infarction (MI), angina pectoris (AP), stroke, and atrial fibrillation (AF) between individual SGLT2 inhibitors.

Results

Median age was 52 years, and 82.5% were men. The median fasting plasma glucose and HbA1c levels were 149 (Q1-Q3:127–182) mg/dL and 7.5 (Q1-Q3:6.9–8.6) %. During a mean follow-up of 814 ± 591 days, 855 HF, 143 MI, 815 AP, 340 stroke, and 139 AF events were recorded. Compared with empagliflozin, the risk of developing HF, MI, AP, stroke, and AF was not significantly different in dapagliflozin, canagliflozin, and other SGLT inhibitors. For developing HF, compared with empagliflozin, hazard ratios of dapagliflozin, canagliflozin, and other SGLT2 inhibitors were 1.02 (95% confidence interval [CI] 0.81–1.27), 1.08 (95% CI 0.87–1.35), and 0.88 (95% CI 0.73–1.07), respectively. Wald tests showed that there was no significant difference in the risk of developing HF, MI, AP, stroke, and AF among individual SGLT2 inhibitors. We confirmed the robustness of these results through a multitude of sensitivity analyses.

Conclusion

The risks for subsequent development of HF, MI, AP, stroke, and AF were comparable between individual SGLT2 inhibitors. This is the first study comparing the wide-range cardiovascular outcomes of patients with DM treated with individual SGLT2 inhibitors using large-scale real-world data.

Age-Dependent Relationship of Hypertension Subtypes With Incident Heart Failure

Background The prevalence of hypertension subtypes changes with age. However, little is known regarding the age-dependent association of hypertension subtypes with incident heart failure (HF). Methods and Results We conducted an observational cohort study including 2 612 570 people (mean age, 44.0 years; 55.0% men). No participants were taking blood pressure-lowering medications or had a known history of cardiovascular disease. Participants were categorized as aged 20 to 49 years (n=1 825 756), 50 to 59 years (n=571 574), or 60 to 75 years (n=215 240). We defined stage 1 hypertension as systolic blood pressure (SBP) 130 to 139 mm Hg or diastolic blood pressure (DBP) 80 to 89 mm Hg and stage 2 hypertension as SBP ≥140 mm Hg or DBP ≥90 mm Hg. Among participants with stage 2 hypertension, isolated diastolic hypertension was defined as SBP <140 mm Hg and DBP ≥90 mm Hg, isolated systolic hypertension as SBP ≥140 mm Hg and DBP <90 mm Hg, and systolic diastolic hypertension as SBP ≥140 mm Hg and DBP ≥90 mm Hg. During a mean follow-up of 1205±934 days, 43 415 HF, 4807 myocardial infarction, 45 365 angina pectoris, 22 179 stroke, and 10 420 atrial fibrillation events occurred. Although the incidence of HF and other cardiovascular disease events increased with age, hazard ratios and relative risk reductions of each hypertension subtype for HF decreased with age. An age-dependent relationship between hypertension subtypes and incident HF was similarly observed in both men and women. Conclusions The contribution of isolated diastolic hypertension, isolated systolic hypertension, and systolic diastolic hypertension to the development of HF and other cardiovascular disease events was attenuated with age, suggesting that preventive efforts for blood pressure control could provide a greater benefit in younger individuals.

Association between proteinuria and incident colorectal cancer: analysis of a nationwide population-based database

OBJECTIVES

This study aimed to assess whether adults with proteinuria were at a higher risk of incident colorectal cancer (CRC) than those without proteinuria using a large-scale population-based database.

DESIGN

A retrospective observational study.

SETTING

The JMDC Claims Database, an administrative health claims database, was used. Data were collected between 2005 and 2020.

PARTICIPANTS

We selected records of participants (n=3 543 705) who underwent health check-ups, including physical examinations, blood tests and urine dipstick tests. We excluded participants who were aged <20 years (n=25 577), had a history of CRC, colorectal disease, renal disease and renal replacement therapy (n=114 888), or had missing data on medications (n=170 145), cigarette smoking (n=14 835), alcohol consumption (n=366 414) or physical activity (n=106 550). Finally, we analysed 2 745 296 participants.

MAIN OUTCOME MEASURES

The primary outcome was CRC at any stage.

RESULTS

Participants were categorised as having no proteinuria (n=2 435 872), trace proteinuria (n=231 153) or positive proteinuria (n=78 271). Over a mean follow-up period of 1189±914 days, 10 615 CRC diagnoses were recorded. The incidence of CRC (95% CI) was lowest in participants without proteinuria (11.7; 95% CI, 11.5 to 11.9 per 10 000 person-years), followed by trace proteinuria (12.5; 95% CI, 11.7 to 13.3 per 10 000 person-years) and positive proteinuria (16.1; 95% CI, 14.6 to 17.7 per 10 000 person-years). After multivariable adjustment, compared with no proteinuria, HRs for incident CRC were 1.20 (95% CI, 1.12 to 1.29) and 1.23 (95% CI, 1.11 to 1.36) for trace and positive proteinuria, respectively. The association between proteinuria and incident CRC existed in participants after multiple imputations for missing data, with a follow-up period of ≥365 days, regardless of age, sex, obesity, hypertension, diabetes mellitus and estimated glomerular filtration rate.

CONCLUSIONS

Trace and positive proteinuria were associated with a greater risk of incident CRC. Assessment of proteinuria could help identify individuals at an increased risk of CRC.

Impact of Left Main Calcium With Chronic Kidney Disease on Outcomes After Percutaneous Coronary Intervention for Left Main Narrowings (from the Milan and New-Tokyo Registry)

Limited data are available about the association between coronary artery calcification and chronic kidney disease severity on clinical outcomes after percutaneous coronary intervention (PCI). This study aimed to assess the association between coronary artery calcification and chronic kidney disease severity on clinical outcomes after PCI. We identified 1,391 patients treated with drug-eluting stent for unprotected left main distal bifurcation lesions (ULMD), including 604 without calcified lesions (noncalcified left main group) and 787 with calcified ULMD (calcified left main group) in Japan and Italy. We divided the calcified group into the following 2 groups: estimated glomerular filtration rate (eGFR) ≥30 (n = 687) and <30 (n = 100) and compared the clinical outcomes. The primary end point was target lesion failure (TLF) at 3 years. TLF was defined as a composite of cardiac death, target lesion revascularization, and myocardial infarction. TLF occurred more frequently in the calcified group (adjusted hazard ratio 1.36, 95% confidence interval 1.08 to 1.71, p = 0.01), especially in calcified ULMD with eGFR <30 (adjusted hazard ratio relative to the other 2 groups 2.59, 95% confidence interval 1.60 to 4.18, p <0.001). In conclusion, the calcified ULMD treated with PCI was associated with poorer clinical outcomes than noncalcified ULMD, especially in those with eGFR <30.

Epstein-Barr Virus-positive Intestinal Diffuse Large B-cell Lymphoma in a Japanese Patient with Celiac Disease: First Reported Case and a Literature Review

A 60-year-old Japanese woman was diagnosed with celiac disease (CeD) and treated with a gluten-free diet. For five years, she had a good clinical course. However, she complained of inappetence and nausea. Colonoscopy revealed ulcerative tumors in the terminal ileum. A histological examination of biopsy specimens from the ulcerative tumor showed diffuse infiltration of large atypical lymphocytes. Immunohistologically, the atypical lymphoid cells were positive for cluster of differentiation (CD) 10 and CD20. Many Epstein-Barr virus-encoded small RNA (EBER)-positive atypical lymphocytes were detected by in situ hybridization. This represents the first reported case of Epstein-Barr virus-positive intestinal diffuse large B-cell lymphoma complicated with CeD.
