Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m², fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m², male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

BACKGROUND: The Hokkaido Study on Environment and Children's Health is an ongoing study consisting of two birth cohorts of different population sizes: the Sapporo cohort and the Hokkaido cohort. Our primary objectives are to (1) examine the effects that low-level environmental chemical exposures have on birth outcomes, including birth defects and growth retardation; (2) follow the development of allergies, infectious diseases, and neurobehavioral developmental disorders, as well as perform a longitudinal observation of child development; (3) identify high-risk groups based on genetic susceptibility to environmental chemicals; and (4) identify the additive effects of various chemicals, including tobacco. METHODS: The purpose of this report is to provide an update on the progress of the Hokkaido Study, summarize recent results, and suggest future directions. In particular, this report provides the latest details from questionnaire surveys, face-to-face examinations, and a collection of biological specimens from children and measurements of their chemical exposures. RESULTS: The latest findings indicate different risk factors of parental characteristics on birth outcomes and the mediating effect between socioeconomic status and children that are small for the gestational age. Maternal serum folate was not associated with birth defects. Prenatal chemical exposure and smoking were associated with birth size and growth, as well as cord blood biomarkers, such as adiponectin, leptin, thyroid, and reproductive hormones. We also found significant associations between the chemical levels and neuro development, asthma, and allergies. CONCLUSIONS Chemical exposure to children can occur both before and after birth. Longer follow-up for children is crucial in birth cohort studies to reinforce the Developmental Origins of Health and Disease hypothesis. In contrast, considering shifts in the exposure levels due to regulation is also essential, which may also change the association to health outcomes. This study found that individual susceptibility to adverse health effects depends on the genotype. Epigenome modification of DNA methylation was also discovered, indicating the necessity of examining molecular biology perspectives. International collaborations can add a new dimension to the current knowledge and provide novel discoveries in the future.

To investigate the risk factors associated with acute renal failure (ARF) after thoracoabdominal aortic aneurysm (TAAA) surgery. A total of 156 patients underwent TAAA repair between January 2009 and December 2017. Renal failure was defined based on the Kidney Disease Improving Global Outcomes criteria. The patients were divided into ARF group and non-ARF group based on the presence/absence of postoperative ARF. The risk factors of ARF were analyzed by univariate analysis and multivariate logistic analysis. The subjects included 111 males and 45 females aged (40.4±10.9) years (range:19-65 years). The surgical reasons included aortic dissection (=130,83.3%),aneurysm (=22,14.1%),and pseudoaneurysm (=4,2.6%). The degrees of repair included Crawford extent I in 6 patients (3.8%),extent Ⅱ in 128 patients (82.1%),extent Ⅲ in 20 patients (12.8%),and extent Ⅳ in 2 patients(1.3%). There were 3 patients presented with aortic rupture and 6 patients received emergent operations. Nine patients (5.8%) died within 30 days after surgery,and 8 patients (5.1%) suffered from permanent paraplegia. Thirty-six patients (23.1%) had ARF after surgery,and 18 of them needed dialysis. Multivariate logistic analysis showed that smoking ( =2.637,95%=1.113-6.250,=0.028),packed red blood cell usage in operation (≥6 U) ( =5.508,95%=2.144-11.930,=0.000),reoperation for bleeding (=3.529,95%=1.298-9.590,=0.013) were independent risk factors for ARF after TAAA repair. Smoking,packed red blood cell usage in operation (≥6 U),reoperation for bleeding are the independent risk factors of ARF after TAAA surgery.

BACKGROUND: Smoking, alcohol use, performing regular physical exercise, dietary habits, and anxiety level may cause platelet activation. We aimed to evaluate the anxiety levels, smoking status, alcohol intake, and sportive habits of donors, and determine their impact on the quality of apheresis-platelets.METHODS: State and Transient Anxiety Inventory (STAI) was used to determine the level of donors' anxiety. STAI has two subscales: S-anxiety scale (STAI-I) and T-anxiety scale (STAI-II), each comprising 20 questions rated on a 4-point Likert scale. Data on smoking, alcohol consumption, and performing regular physical exercise were obtained from a questionnaire filled out before donation. Flow cytometric analysis was used to quantify activated platelets.RESULTS: The STAI-I level of 86 participants was normal, while that of 12 was higher. No significant difference was found in the active platelet absolute count [1.8×10¹¹ (2.7) and 1.4×10¹¹ (1.3), respectively; P=0.665] between donors with normal STAI-I levels and those with higher STAI-I levels. Of 98 donors, 42 had normal STAI-II levels, while 56 had higher STAI-II levels. No significant difference was found in the active platelet absolute count [2.3×10¹¹ (3.1) and 1.5×10¹¹ (2.3), respectively; P=0.224] between donors with normal STAI-II levels and those with higher STAI-II levels. Platelet counts of individuals who perform regular physical exercise were significantly higher than those of individuals who did not perform regular physical exercise (6.3±1.4×10¹¹ vs. 5.5±1.4×10¹¹).CONCLUSION: The quality of apheresis platelets is not affected by anxiety levels and lifestyle characteristics of blood donors. There is no need to organize apheresis blood donor pool considering with these subjects.

BACKGROUND: It is unclear whether impaired pulmonary function serves as a risk factor for decreased renal function. This study investigated the association between the forced vital capacity (FVC) and chronic kidney disease (CKD) in middle-aged and elderly men.METHODS: We investigated the association between FVC and CKD in 412 Korean men aged ≥50 years, without diabetes, who have not received treatment for chronic lung disease. CKD was defined based on evidence of renal tissue damage or reduced renal function indicated by estimated glomerular filtration rate < 60 mL/min/1.73 m² or proteinuria level ≥1+. We assessed the association between FVC and CKD using multivariate logistic regression analysis after adjusting for confounders.RESULTS: The overall prevalence of CKD was 29.2% in the study population. Multivariate logistic regression analysis showed that the odds ratio with a 95% confidence interval for CKD was 0.96 (0.92–0.99) with a 1% increment in FVC after adjusting for age, body mass index, smoking status, alcohol intake, regular exercise, systolic and diastolic blood pressures, fasting plasma glucose, triglyceride, and high-density lipoprotein-cholesterol levels, as well as antihypertensive and antidyslipidemic medications.CONCLUSION: We observed that FVC was independently and inversely associated with CKD. This finding suggests that careful monitoring of renal function is necessary to evaluate possible kidney dysfunction in patients with decreased FVC.

BACKGROUND: Albuminuria is an indicator of renal impairment in patients with diabetes or hypertension. Studies on the effect of sleep duration on albuminuria in hypertension patients are limited. Hence, the purpose of this study was to investigate the association between sleep duration and albuminuria in Korean hypertension patients.METHODS: In this cross-sectional study, data on hypertensive patients were obtained from the fifth Korean National Health and Nutrition Examination Survey (2011–2012). Participants were classified into five groups according to self-reported sleep duration. Multiple logistic regression analyses were performed to determine the association between sleep duration and albuminuria.RESULTS: When the sleep duration was shorter than 5 hours or longer than 9 hours, the odds ratio (OR) for albuminuria was significantly higher. After adjusting for age, sex, diabetes, hemoglobin A1c, systolic blood pressure, depressive symptom, stress status, smoking status, drinking habit, triglycerides, estimated glomerular filtration rate, and body mass index, ORs (95% confidence interval) for sleep durations of ≤5 hours and ≥9 hours were 1.69 (1.14–2.51) and 2.00 (1.22–3.26), respectively.CONCLUSION: This study showed that a sleep duration of ≤5 hours or ≥9 hours was associated with the high prevalence of albuminuria in Korean hypertension patients.

BACKGROUND: The ankle-brachial index (ABI) is a simple, noninvasive clinical test that is useful in the diagnosis of peripheral artery disease (PAD). The borderline ABI value is 0.91–0.99 and has also been reported in endothelial dysfunction and preclinical PAD. We investigated the relationship between resting heart rate as a surrogate marker of autonomic balance and borderline ABI in apparently healthy individuals.METHODS: We evaluated the association between resting heart rate and borderline ABI in 618 participants (348 male and 270 female) in a health examination program. The odds ratios for borderline ABI were calculated using a multivariable logistic regression analysis after adjusting for confounding variables across heart rate quartiles (Q1≤56, Q2=57–62, Q3=63–68, and Q4≥69 beats/min).RESULTS: The overall prevalence of borderline ABI was 13.9%. The age- and sex-adjusted resting heart rate was significantly higher in the borderline ABI group than in the control group (66.9±0.9 vs. 63.0±0.4 beats/min, P < 0.001). The odds ratios (95% confidence intervals) for the borderline ABI in each heart rate quartile were 1.00, 1.04 (0.43–2.52), 1.69 (0.73–3.93), and 3.52 (1.55–7.97) after adjusting for age, sex, smoking status, alcohol intake, regular exercise, body mass index, systolic blood pressure, fasting plasma glucose level, triglyceride level, high-density lipoprotein-cholesterol level, white blood cell count, C-reactive protein level, uric acid level, γ-glutamyltransferase level, hypertension medication, diabetes medication, and dyslipidemia medication.CONCLUSION: These findings indicate that a higher resting heart rate is independently associated with borderline ABI.

BACKGROUND: Insulin resistance syndrome is recognized as a risk factor for cardiovascular disease (CVD) and type 2 diabetes mellitus (DM). Even though early management and prevention during the pre-DM stage is emphasized, few studies have investigated the risk of insulin resistance and CVD in individuals with normal blood glucose. This study investigates the effectiveness of the high sensitivity C-reactive protein (hs-CRP) test as a preventative measure by examining the relationship between hs-CRP and a homeostasis model assessment of insulin resistance (HOMA-IR) in adult men without DM.METHODS: Our study included 1,924 men who were ≥20 years of age, from the 2015 Korean National Health and Nutrition Examination Survey. Based on fasting glucose levels, subjects were divided into two categories: normal and impaired fasting glucose (IFG).RESULTS: Student's t-test was used to compare the means of the normal and IFG categories, and hs-CRP and HOMA-IR showed significantly lower values for all variations, except height and smoking, at a significance level of 0.001. All subjects were classified into quadrant groups according to hs-CRP values, and ANCOVA was performed to compare the HOMA-IR average of each group. The mean IR did not significantly differ between cohorts, except for in the IFG category of one group.CONCLUSION: In adult men without DM, hs-CRP did not significantly correlate with HOMA-IR, except in the IFG category. This indicates that the risk of CVD increases continuously in the normal blood sugar range. Further studies are needed to improve the usefulness of the high sensitivity hs-CRP test.

PURPOSE: Cigarette smoking (CS) is one of the major risk factors of cerebral atherosclerotic disease, however, its level of contribution to extracranial and intracranial atherosclerotic stenosis (ECAS and ICAS) was not fully revealed yet. The purpose of our study was to assess the association of CS to cerebral atherosclerosis along with other risk factors. MATERIALS AND METHODS: All consecutive patients who were angiographically confirmed with severe symptomatic cerebral atherosclerotic disease between January 2002 and December 2012 were included in this study. Multivariate logistic regression analyses were performed to identify risk factors for ECAS and ICAS. Thereafter, CS group were compared to non-CS group in the entire study population and in a propensity-score matched population with two different age-subgroups. RESULTS: Of 1709 enrolled patients, 794 (46.5%) had extracranial (EC) lesions and the other 915 (53.5%) had intracranial (IC) lesions. CS group had more EC lesions (55.8% vs. 35.3%, P<0.001) whereas young age group (<50 years) had more IC lesion (84.5% vs. 47.6%, P<0.001). In multivariate analysis, seven variables including CS, male, old age, coronary heart disease, higher erythrocyte sedimentation rate, multiple lesions, and anterior lesion were independently associated with ECAS. In the propensity-score matched CS group had significant more EC lesion compared to non-CS group (65.7% vs. 47.9%) only in the old age subgroup. CONCLUSION: In contrast to a significant association between CS and severe symptomatic ECAS shown in old population, young patients did not show this association and showed relatively higher preference of ICAS.
