Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), is a pervasive chronic disease that affects millions of people worldwide. It predisposes individuals to a range of severe microvascular and macrovascular complications, which drastically impact the patient's quality of life and increase mortality rates owing to various comorbidities. This extensive review explores the intricate pathophysiology underlying diabetic complications, focusing on key mechanisms, such as atherosclerosis, insulin resistance, chronic inflammation, and endothelial dysfunction. It also highlights recent therapeutic advancements, including the introduction of SGLT2 inhibitors and GLP-1 receptor agonists, which provide benefits beyond glycemic control and offer cardiovascular and renal protection. Furthermore, the future position of SGLT2 inhibitors and GLP-1 receptor agonists in terms of the prevention of diabetes and macrovascular diseases will be discussed. Considering the differences in insulin secretion capacity between Western and Asian patients, including Japanese patients, we propose a treatment strategy for high-quality diabetes in Japan.

Apolipoprotein E (apoE) is a key apoprotein in lipid transport and is susceptible to genetic mutations. ApoE variants have been studied for four decades and more than a hundred of them have been reported. This paper presents an up-to-date review of the function and structure of apoE in lipid metabolism, the E2, E3, and E4 isoforms, the APOE gene, and various pathologies, such as familial type III hyperlipidemia and lipoprotein glomerulopathy, caused by apoE variants. Alzheimer's disease was barely mentioned in this paper. But this review should help researchers obtain a comprehensive overview of human apoE in lipid metabolism.

This review introduces "space prescribing," an innovative healthcare approach that incorporates the physical environment's role in promoting health beyond traditional clinical settings. Recognizing that individuals spend a significant amount of time outside clinical environments, this approach explores the therapeutic potential of natural and built environments in improving well-being and managing diseases, particularly cardiovascular and mental health conditions.Traditional healthcare models focus on treatments in hospital and clinic settings. However, evidence suggests that environmental factors profoundly influence health outcomes. Space prescribing recommends specific environments that encourage healthier lifestyles and enhance wellbeing. This concept includes social prescribing, in which healthcare professionals direct patients to community-based, non-medical activities such as art classes and sports, acknowledging that well-being transcends biological factors.This review also highlights "Cultural Ecosystem Services" (CES) in health through stress reduction, social connections, and physical activity. For cardiovascular health, elements such as green spaces and urban design are vital for managing conditions, such as hypertension and heart disease. Similarly, the configuration of indoor and outdoor spaces plays a crucial role in mental health. Therapeutic landscapes, including community gardens and culturally enriched urban areas, support mental health recovery, foster community engagement and reduce isolation.In conclusion, space prescribing advocates an integrated approach that considers the physical and social environments as fundamental components of health promotion. This strategy aims to mitigate health disparities and enhance the quality of life, while making health-enhancing activities accessible in urban and rural settings. Through this holistic approach, space prescribing has the potential to transform public health by strategically utilizing environmental designs to support health outcomes.

Aims: Previous evidence suggests that serum lung cancer biomarkers are associated with inflammatory conditions; however, their relationship with peripheral arterial stiffness remains unclear. Therefore, the present study investigated the relationship between serum lung cancer biomarkers and peripheral arterial stiffness in middle-aged Chinese adults.

Methods: In total, 3878 middle-aged Chinese adults were enrolled in this study. Increased peripheral arterial stiffness was assessed using the brachial-ankle pulse wave velocity and ankle-brachial index. Univariate and multivariate logistic regression analyses were used to determine the independent effects of serum lung cancer biomarkers on the risk of increased peripheral arterial stiffness. A receiver operating characteristic curve analysis was used to assess the diagnostic ability of serum lung cancer biomarkers in distinguishing increased peripheral arterial stiffness.

Results: Serum levels of carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), cytokeratin-19 fragment 21-1, and pro-gastrin-releasing peptide were higher in subjects with increased peripheral arterial stiffness than in those without (P＜0.05). After adjusting for other risk factors, serum CEA and NSE levels were found to be independently associated with increased peripheral arterial stiffness. The corresponding adjusted odds ratios (ORs) for increased peripheral arterial stiffness in CEA level quartiles were 1.00, 1.57, 2.15, and 6.13. The ORs for increased peripheral arterial stiffness in the quartiles of NSE levels were 1.00, 4.92, 6.65, and 8.01.

Conclusions: Increased serum CEA and NSE levels are closely linked to increased peripheral arterial stiffness, and high serum CEA and NSE levels are potential risk markers for peripheral arterial stiffness in middle-aged Chinese adults.

Aims: Elevated lipoprotein (a) (Lp[a]), predominantly determined by genetic variability, causes atherosclerotic cardiovascular disease (ASCVD), particularly in patients with familial hypercholesterolemia (FH). We aimed to elucidate the clinical impact of Lp(a) and cumulative exposure to low-density lipoprotein cholesterol (LDL-C) on CAD in patients with FH.

Methods: One hundred forty-seven patients clinically diagnosed with heterozygous familial hypercholesterolemia (HeFH) were retrospectively investigated. Patients were divided into 2 groups according to the presence of CAD. Their clinical characteristics and lipid profiles were evaluated.

Results: There were no significant differences in untreated LDL-C levels between the 2 groups (p=0.4), whereas the cumulative exposure to LDL-C and Lp(a) concentration were significantly higher in patients with CAD (11956 vs. 8824 mg-year/dL, p＜0.01; 40 vs. 14 mg/dL, p＜0.001, respectively). A receiver operating characteristic (ROC) curve analysis demonstrated that the cutoff values of Lp(a) and cumulative LDL-C exposure to predict CAD in patients with FH were 28 mg/dL (AUC 0.71) and 10600 mg-year/dL (AUC 0.77), respectively. A multivariate analysis revealed that cumulative LDL-C exposure ≥ 10600 mg-year/dL (p＜0.0001) and Lp(a) level ≥ 28 mg/dL (p＜0.001) were independent predictors of CAD. Notably, the risk of CAD remarkably increased to 85.7% with smoking, Lp(a) ≥ 28 mg/dL, and cumulative LDL-C exposure ≥ 10600 mg-year/dL (odds ratio: 46.5, 95%CI: 5.3-411.4, p＜0.001).

Conclusions: This study demonstrated an additive effect of Lp(a) and cumulative LDL-C exposure on CAD in patients with HeFH. Interaction with traditional risk factors, particularly smoking and cumulative LDL-C exposure, enormously enhances the cardiovascular risk in this population.

Aim: This study investigated the associations of the surface charge of low-density lipoprotein (LDL) with the serum LDL-cholesterol and atherosclerosis levels in a community-based Japanese population.

Methods: The study had a cross-sectional design and included 409 community residents aged 35-79 years who did not take medications for dyslipidemia. The potential electric charge of LDL and the zeta potential, which indicate the surface charge of LDL, were measured by laser Doppler microelectrophoresis. The correlations of the zeta potential of LDL (-mV) with the serum LDL-cholesterol levels (mg/dL), cardio-ankle vascular index (CAVI), and serum high-sensitivity C-reactive protein (hsCRP) levels (log-transformed values, mg/L) were examined using Pearson's correlation coefficient (r). Linear regression models were constructed to examine these associations after adjusting for potential confounding factors.

Results: A total of 201 subjects with correctly stored samples were included in the primary analysis for zeta potential measurement. An inverse correlation was observed between the LDL zeta potential and the serum LDL-cholesterol levels (r=-0.20; p=0.004). This inverse association was observed after adjusting for sex, age, dietary cholesterol intake, smoking status, alcohol intake, body mass index, and the serum levels of the major classes of free fatty acids (standardized β=-6.94; p=0.005). However, the zeta potential of LDL showed almost no association with CAVI or the serum hsCRP levels. Similar patterns were observed in the 208 subjects with compromised samples as well as all the original 409 subjects.

Conclusion: A higher electronegative surface charge of LDL was associated with lower serum LDL-cholesterol levels in the general Japanese population.

Aims: Little data exists for evaluating the prevalence and patient characteristics of familial hypercholesterolemia (FH) according to the latest 2022 guidelines for FH published by the Japan Atherosclerosis Society (JAS), which revised the Achilles tendon thickness (ATT) threshold from 9.0 mm in both sexes to 8.0 mm in men and 7.5 mm in women. This study used a nationwide registry of patients with acute coronary syndrome (ACS) to evaluate the prevalence of FH according to the latest diagnostic criteria for FH and to investigate the application of Achilles tendon imaging in the diagnosis of FH.A previous prospective observational study at 59 Japanese centers involving consecutive patients with ACS who were managed between April 2015 and August 8, 2016 was conducted to explore lipid management and persistent risk in patients hospitalized for ACS (EXPLORE-J). The study population consisted of 1,944 EXPLORE-J enrollees.

Results: According to the diagnostic criteria for FH in the 2022 JAS guidelines, the prevalence of probable or definite was among patients with ACS was 6.6% (127/1944). Among patients with premature ACS (male, age ＜55 years; female, age ＜65 years), the prevalence of FH was 10.1% (43/427). The mean ages were of the probable FH and definite FH groups were 59.9 and 61.0 years, respectively, while the mean age of the possible-or-unlikely FH group was 66.4 years (significantly older). Relative to the possible-or-unlikely FH group, the low-density lipoprotein cholesterol (LDL-C) levels were similar in the probable FH group and and significantly higher in the definite FH group.

Conclusions: The prevalence of FH was considerably higher than previously reported, especially for patients with premature ACS. The age and LDL-C levels of the patients in the probable FH and definite FH groups were similar.

Aim: The constellation of cardiovascular disease (CVD) risk factors greatly impacts the lifetime risk (LTR) of incident CVD, but the LTR has not been thoroughly evaluated in the Japanese population.

Methods: We conducted a prospective study involving a total of 25,896 individuals 40-69 years old without a history of CVD in 1995 (Cohort I) and 1993-1994 (Cohort II) in Japan. CVD risk factors (blood pressure, non-high-density lipoprotein [HDL] cholesterol levels, smoking status, and glucose concentrations) were used to stratify them by risk. The sex-specific LTR of incident coronary heart disease, stroke, atherosclerotic CVD, and total CVD were estimated for participants 45 years old in the 4 risk categories with the cumulative incidence rate, adjusting for the competing risk of death.

Results: We found apparent differences in the LTR of total CVD according to the risk stratification. Individuals with ≥ 2 of the risk factors of blood pressure ≥ 140/90 mmHg or treated, non-HDL cholesterol level ≥ 170 mg/dL or treated, current smoker, and diabetes had substantially higher adjusted LTRs of CVD than those in other groups, with a LTR of 26.5% (95% confidence interval, 24.0%-29.0%) for men and 15.3% (13.1%-17.5%) for women at 45 years. The LTR of incident stroke was the highest among CVDs, and the presence of hypertension and diabetes mellitus strongly influenced the LTR of total CVD.

Conclusion: The impact of risk accumulation on LTR of CVD was greater in men, and 1 in 4 men with ≥ 2 major risk factors at 45 years of age developed CVD in their lifetime.

Aims: The impact of weekend/holiday and nighttime hospitalization on functional outcomes and long-term trends in stroke patients is unclear. We examined functional and life outcomes and changes over time.

Methods: We analyzed the clinical data of 203,176patients for hospital arrival day of week and 76,442patients for arrival times using Japan Stroke Data Bank. The endpoints were favorable outcome (Modified Rankin Scale[mRS]0-2), unfavorable outcome(mRS 5-6), and in-hospital mortality. We calculated odds ratios(OR) and 95% confidence interval(CI) of weekends/holidays and off-hours versus weekdays and on-hours for 2000-2009 and 2010-2020 using a mixed-effect multivariate model adjusted for confounding factors and evaluated interactions. Thereafter, we performed to check for year trends.

Results: All endpoints were worse in weekend/holiday admissions for all stroke and in off-hours hospitalization for total stroke(TS), ischemic stroke(IS), and intracerebral hemorrhage(ICH). The adjusted ORs for favorable outcomes of weekend/holiday admissions were TS, 0.90(0.87-0.93); IS, 0.89(0.86-0.93); ICH, 0.91(0.84-0.98) and unfavorable outcome TS, 1.04(1.002-1.08) IS, 1.06(1.01-1.11). Off-hour hospitalization had adjusted ORs for favorable outcome(TS, 0.86 [95% CI: 0.82-0.91]; IS, 0.90 [0.84-0.95]; ICH, 0.85 [0.75-0.96]), unfavorable outcome(TS, 1.14 [1.07-1.22]; IS, 1.13 [1.04-1.23]; ICH, 1.15 [1.01-1.31]), and mortality (TS, 1.15 [1.05-1.26]; IS, 1.17 [1.04-1.32]). For IS, the incidence of unfavorable outcomes during off-hours was significantly lower in 2010-2020 than in 2000-2009; after adjusting for reperfusion therapy, it was no longer significant.

Conclusion: Stroke patients admitted on weekends/holidays and off-hours had worse functional and life outcomes. Functional outcomes for off-hour admission for IS improved at 10-year intervals, possibly due to improvements in stroke care systems.
