RESUMO
This study evaluated the association between fibrosis-4 (FIB 4) index and arterial damage or future risk of coronary heart disease (CHD) in type 2 diabetes. The study subjects were 253 patients with type 2 diabetes. The FIB4 index, as a marker of hepatic fibrosis based on age, aspartate aminotransferase and alanine aminotransferase levels, and platelet count, was calculated for all subjects. Carotid intima-media thickness (IMT), carotid artery calcification (CAC), and aortic arch calcification (AAC) grade (0-2) were assessed as atherosclerotic variables. The Suita score was calculated as the future risk of coronary heart disease (CHD). We assessed whether the FIB4 index was associated with both atherosclerotic variables and the Suita score. FIB4 index was significantly associated with IMT (r = 0.241, P < 0.001) and Suita score (r = 0.291, P < 0.001). Subjects with CAC showed a significantly higher FIB4 index score compared to subjects without (1.70 ± 0.74 and 1.24 ± 0.69, respectively, P < 0.001), whereas the FIB4 index was significantly elevated with a higher grade of AAC (1.24 ± 0.74, 1.56 ± 0.66, and 1.79 ± 0.71, respectively, P < 0.001). Linear regression analysis adjusted for clinical characteristics indicated that the FIB4 index was positively associated with IMT, Suita score, CAC, and AAC grade (ß = 0.241, P=0.004; ß = 2.994, P < 0.001; ß = 0.139, P=0.001; and ß = 0.265, P < 0.001, respectively). FIB4 index is closely associated with arterial damage and future risk of CHD in type 2 diabetes.
RESUMO
BACKGROUND: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: CAVI is more closely associated than baPWV with arterial damage and risk of CVD in patients with diabetes.

This study evaluated the associations between aortic arch calcification (AAC) with pericardial fat (PF) mass detected on a single chest X-ray image and predictive variables of future cardiovascular disease (CVD). The subjects were 353 patients treated with at least one of the hypertension, dyslipidemia or diabetes. All subjects were evaluated for AAC; divided into 3 groups with AAC grades of 0, 1, or 2; and examined for the presence of PF. Carotid intima-media thickness (IMT, n = 353), cardio-ankle vascular index (CAVI, n = 218), the Suita score (n = 353), and cardiovascular risk points defined in the Hisayama study (n = 353), an assessment of the risk of future cardiovascular disease, were measured. The relationship of AAC grades, with or without PF, and CVD risks was evaluated. The IMT (1.62 ± 0.74 mm, 2.33 ± 1.26, and 2.43 ± 0.89 in patients with AAC grade 0, 1 and 2, respectively, p < 0.001), CAVI (8.09 ± 1.32, 8.71 ± 1.32, and 9.37 ± 1.17, respectively, p < 0.001), the Suita score (46.6 ± 10.7, 51.8 ± 8.3, and 54.2 ± 8.2, respectively, p < 0.001), and cardiovascular risk points (8.5 ± 2.6, 10.6 ± 2.3, and 11.5 ± 2.3, respectively, p < 0.001) were significantly elevated with AAC progression. Multinomial logistic regression analysis adjusted for clinical characteristics showed that the relative risk ratios of the Suita score or cardiovascular risk points were elevated according to the progress of AAC grade with PF. Therefore, aortic arch calcification with pericardial mass detected on a single chest X-ray image is closely associated with the predictive variables of future CVD.

The authors assessed the association between the ratio of urinary activity of N-acetyl-ß-D-glucosaminidase (NAG) to creatinine and the brachial-ankle pulse wave velocity (baPWV) in patients without overt diabetes mellitus (DM). This was a cross-sectional study of 233 patients who had an estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m(2) and no history of kidney disease. Patients were divided into two groups: high NAG group (>5.8 U/g creatinine) and low NAG group (≤5.8 U/g creatinine). Mean baPWVs of the high NAG group were significantly higher than those of the low NAG group in both the eGFR ≥30 and <60 tertiles and the eGFR ≥60 and <90 tertiles. The baPWV was positively correlated with NAG in all patients (r=0.341, P<.001). Stepwise multivariate regression analysis showed that the baPWV was significantly related with NAG, age, and systolic blood pressure. Elevated NAG is related to elevated arterial stiffness in patients without DM.

OBJECTIVE: Current data indicate that the rate of trauma in children during gymnastic formation is increasing, especially while creating a structure with a certain height, such as the human pyramid. The goal of the present study was to clarify the clinical characteristics of these injuries. METHODS: In this single-institution review, all children treated for a gymnastic formation-related injury at Nippon Medical School Hospital from 2013 through 2015 were identified through the institution's registry. The injury mechanism was classified, and injury severity, interventions, and outcome were examined. RESULTS: Eight children were treated for a gymnastic formation-related injury. They were 7 boys and 1 girl aged 10 to 15 years (mean age, 13.1±1.8 years). Neurotrauma ranging from concussion to spinal cord injury without radiographic abnormality occurred in 6 patients (75%). No intracranial hemorrhagic lesions were detected. The Glasgow Coma Scale score on arrival was 15 in all 8 patients, and neurological deficits were present in 1 patient. No patient required surgical intervention. All patients made a full recovery after discharge from the hospital. No patients died. The average follow-up period was 2.1±0.9 weeks. CONCLUSIONS: Neurotrauma is a frequent result of gymnastic formation accidents in children. Healthcare workers and teachers should recognize this type of injury, and public education that targets parents should be introduced.

BACKGROUND: This study assessed the relationship between the serum level of 1,5-anhydroglucitol (1,5-AG), a marker of postprandial hyperglycemia, and the ratio of the urinary activity of N-acetyl-ß-D-glucosaminidase (NAG) to creatinine (NAG index) in patients with type 2 diabetes mellitus. SUBJECTS AND METHODS: This was a cross-sectional study with 153 patients who had an estimated glomerular filtration rate of ≥60 mL/min/1.73 m(2) and no proteinuria and who had never been treated with oral hypoglycemic agents or insulin. On the basis of 1,5-AG levels, the patients were divided into a High 1,5-AG group (>14.0 µg/mL) and a Low 1,5-AG group (≤14.0 µg/mL). RESULTS: The logarithmically transformed NAG index was significantly higher in the Low 1,5-AG group than in the High 1,5-AG group when all glycated hemoglobin (HbA1c) levels were included. The logarithmically transformed NAG index was lowest in the High 1,5-AG group with an HbA1c level of ≤6.4% and was highest in the Low 1,5-AG group with an HbA1c level of ≥7.5%. Multivariate regression analysis showed that the NAG index had a higher independent association with 1,5-AG than with HbA1c or the fasting plasma glucose level. In all models, multivariate regression analyses showed that the NAG index was correlated with age. CONCLUSIONS: These results suggest that postprandial hyperglycemia correlates with early renal tubule injury in type 2 diabetes mellitus.

AIMS: This study aimed to evaluate the relationship between aortic arch calcification (AAC) detectable on chest X-ray films and plasma diacron-reactive oxygen metabolites (d-ROMs) in patients with type 2 diabetes but without cardiovascular disease. METHODS: Forty-nine patients with type 2 diabetes but without cardiovascular disease were evaluated with chest X-ray examinations and divided into those with AAC (n=26) and those without AAC (n=23). Biochemical variables, including plasma levels of d-ROMS, high-sensitivity C-reactive protein (hsCRP), plasminogen activator inhibitor-1 (PAI-1), and lipoprotein(a) (Lp(a)), were evaluated after an overnight fast. The relationships of AAC with both inflammation and oxidative-stress variables were evaluated. RESULTS: The plasma level of d-ROMs in subjects with AAC was significantly higher than that in subjects without AAC, whereas plasma levels of hsCRP, PAI-1, and Lp(a) in subjects with AAC were higher, but not significantly so, than those in subjects without AAC. Multivariate linear regression analysis with AAC grade as the dependent variable and plasma levels of d-ROMs, hsCRP, PAI-1, or Lp(a) as independent variables demonstrated a significant association of AAC grade with plasma levels of d-ROMs but not with plasma levels of hsCRP, PAI-1, or Lp(a). CONCLUSIONS: The plasma level of d-ROMs is associated with AAC in patients with type 2 diabetes but without cardiovascular disease. Hence, the results of the present study suggest that AAC in these patients is strongly associated with oxidative stress. Furthermore, patients with type 2 diabetes and AAC may be at high risk for the development and progression of various diabetic complications induced by oxidative stress.
