Changes of serum ceruloplasmin (Cp) levels have been reported in many conditions including diabetes mellitus (DM), in which the serum Cp levels were increased. In this study, we have examined the influence of aging on serum Cp levels in normal individuals and in individuals with DM. Serum Cp levels were measured in 85 outpatients with type 2 diabetes (type 2 DM group) as well as in 71 healthy individuals (control group). All patients recruited for this study were negative for the glutamic acid decarboxylase (GAD) antibody. The subjects were sub-grouped based on their ages (<55 and 55 < or =). The serum Cp levels in the control group increased significantly with aging (r=0.325, p<0.0055), while levels in the type 2 DM group did not (r=0.091, p=0.4079). The levels in the type 2 DM group (<55) were significantly higher than those in the control group (<55) (p = 0.0029), while the Cp levels in the type 2 DM group (55 < or =) were not different from those in the control group (55 < or =) (p=0.4187). An age-related increase of serum Cp levels was observed in normal individuals, but this change was not observed in type 2 DM patients since serum Cp levels in type 2 DM patients of all ages were similar to the levels in normal elderly individuals.
The prevalence of type 2 diabetes is increasing rapidly, particularly among younger age groups. Estimates suggest that people with diabetes die, on average, 6 years earlier than people without diabetes. We aimed to provide reliable estimates of the associations between age at diagnosis of diabetes and all-cause mortality, cause-specific mortality, and reductions in life expectancy.
Abstract Self-rated health (SRH) is a predictive factor for health-related prognoses such as mortality. This study aimed to comprehensively investigate the risk factors for poor SRH in the general population of Japan, focusing on the combination of the number of teeth and self-rated mastication. Individuals aged at least 40 years in Yamagata Prefecture, Japan, were surveyed from 2017 to 2021. The participants answered a self-administered postal survey on lifestyle factors, medical history, physical and mental conditions, oral health, and dietary intake, and 6,739 participants were included. Multivariate logistic regression analysis showed that individuals with less than 20 teeth and who bite tightly on one side or neither side were at a 1.422- and 1.952-fold significantly higher risk, respectively, of poor SRH than individuals with at least 20 teeth and who bite tightly on both sides. Moreover, individuals who had less than 20 teeth but could bite tightly on both sides did not have a significant risk compared to those who had at least 20 teeth and could bite tightly on both sides. Regarding individuals with more than 20 teeth, there was no difference between those who could and could not bite tightly on both sides, although the odds ratios for poor SRH tended to increase for those who could not bite on one side or neither side. Our results emphasize the importance of having at least 20 teeth without periodontal disease and oral rehabilitation using a type of prostheses for SRH, even with less than 20 teeth.
Aim The present study aimed to evaluate the relationship between the change of carotid intima‐media thickness ( CIMT ) and clinical characteristics in J apanese patients without a history of cardiovascular disease. Methods The study participants were 149 J apanese patients without a history of cardiovascular disease treated in our outpatient department. The in all participants CIMT was measured with ultrasonography at baseline and after a mean interval of 2.4 years. Study participants were divided into a middle‐aged group (younger than 65 years: n = 59) and an elderly group (65 years or older: n = 90). The annual CIMT change (Δ CIMT ) was calculated, and the associations between Δ CIMT and clinical characteristics, including age, were evaluated in both groups. Results The Δ CIMT was significantly correlated with age in all participants ( r = 0.222; P < 0.05) and in elderly participants (r = 0.234; P < 0.05), but was not correlated with other risk factors. The annual Δ CIMT was significantly higher in elderly participants (0.015 ± 0.096 mm) than in middle‐aged participants (–0.018 ± 0.088 mm; P < 0.05). Multivariate linear regression analysis with Δ CIMT as a dependent variable and risk factors as independent variables showed that Δ CIMT was significantly associated with age in all participants (β = 0.002; P < 0.05) and in elderly participants (β = 0.004; P < 0.05), but not with other risk factors. Conclusions Annual CIMT change is associated with age, rather than with other clinical characteristics, including traditional cardiovascular risk factors, such as diabetes and hypertension, in elderly J apanese patients without a history of cardiovascular disease.

This study aimed to compare the usefulness of arterial stiffness parameters, cardio-ankle vascular index (CAVI) and brachial-ankle pulse wave velocity (baPWV), for evaluating arterial damage and risk of cardiovascular disease (CVD) in subjects with diabetes.The study subjects were 277 patients with type 1 or type 2 diabetes. All subjects were evaluated for vascular stiffness using CAVI (n = 154) or baPWV (n = 123). Carotid intima-media thickness (IMT) and the Suita score were also measured because these are established risk factors for future CVD. Associations of both CAVI and baPWV with these established parameters were evaluated in all subjects, and then in 174 subjects with adjustment for covariates by using propensity score matching.In all subjects, CAVI and baPWV correlated significantly with both IMT (r = 0.462, P < 0.001, and r = 0.212, P = 0.019, respectively) and the Suita score (r = 0.573, P < 0.001, and r = 0.373, P < 0.001, respectively). The correlation between CAVI and IMT was more significant than that between baPWV and IMT (Z = 2.33, P = 0.020). Similarly, the correlation between CAVI and the Suita score was more significant than that between baPWV and the Suita score (Z = 2.13, P = 0.033). After adjustment by propensity score matching, significant correlations between CAVI and IMT (r = 0.432 P < 0.001) and between CAVI and the Suita score (r = 0.544, P < 0.001) were preserved, though only the association between baPWV and the Suita score was significant (r = 0.289, P = 0.007) while that between baPWV and IMT showed no significance. Again, CAVI showed a significant association with the Suita score than baPWV (Z = 2.02, P = 0.043).CAVI is more closely associated than baPWV with arterial damage and risk of CVD in patients with diabetes.
