- Abstract
AIMS: The plasma protein growth arrest-specific 6 (Gas6) is important to the inflammatory process and involved in the development of diabetic renal and vascular complications. Recently, Gas6 protein also represents a novel independent risk factor of type 2 diabetes. We further investigated the association of c.843+7G>A Gas6 polymorphism and type 2 diabetes. METHODS: A total of 278 adults, including 96 with normal glucose tolerance (NGT), 82 with impaired glucose tolerance (IGT), and 100 with type 2 diabetes were recruited. All subjects were genotyped for c.843+7G>A Gas6 polymorphism. RESULTS: Plasma Gas6 concentrations were significantly lower among patients with type 2 diabetes compared to subjects with IGT and NGT. Subjects with Gas6 c.843+7AA genotype had higher Gas6 levels and lower glucose values than GG genotype. The AA genotype and A allele were less frequent in patients with type 2 diabetes compared with NGT subjects. In univariate analysis, the AA genotype was found to be associated with a decreased risk for type 2 diabetes. Moreover, the association was even stronger after adjustment for established diabetes risk factors. CONCLUSIONS: The Gas6 c.843+7AA genotype and A allele are less prevalent in type 2 diabetes, which may have a protective role for type 2 diabetes. [ABSTRACT FROM AUTHOR]

- Abstract
To investigate the association between plasma leptin and adiponectin and insulin sensitivity in children, 580 school children (294 boys and 286 girls) with mean age of 13.3 years (12-16 years) were randomly selected from the Taipei Children Heart Study. Baseline measurements included body weight, body mass index (BMI), plasma glucose, insulin, proinsulin, leptin and adiponectin levels. Insulin resistance and beta-cell function were assessed using the method of homeostatic model, HOMA-IR and HOMA-beta, respectively. We found that girls had higher levels of plasma leptin, adiponectin and HOMA-beta than boys. There was no significant difference in HOMA-IR between boys and girls. Plasma leptin concentrations were positively correlated with body weight, BMI, insulin and proinsulin concentrations, HOMA-IR and HOMA-beta, whereas plasma adiponectin levels were inversely associated with body weight, BMI and proinsulin levels in both sexes. In girls, adiponectin concentrations were negatively correlated with insulin concentration and HOMA-IR. In multiple regression analyses, plasma leptin was more positively associated with insulin and proinsulin levels, HOMA-IR and HOMA-beta than was adiponectin in boys. This association persisted even after adjusting for body weight, BMI and pubertal status. In conclusion, plasma leptin was more strongly associated with insulin sensitivity and beta-cell function than was adiponectin among children, particularly in boys. [ABSTRACT FROM AUTHOR]

Chu W and Chu NF
- Abstract
Background: Social innovation is often used as a mechanism to jump-start public-private partnerships to leverage resources to achieve social impact; the analysis of sustainability and the impact of corporate social responsibility (CSR) cannot be emphasized enough. Due to advances in the information and communication technology industry in Taiwan, this paper aims to explore whether these advancements drive CSR as a form of social innovation to meet health needs in Taiwan., Methodology: This paper uses a case study to look at CSR programs in the health sector in Taiwan. Corporations with diverse missions and different CSR approaches that are available on the internet are selected. The analysis of the case study takes a qualitative, exploratory approach to shed light on current initiatives., Results: The majority of CSR programs in Taiwan are private sector activities that emerged during the COVID-19 pandemic; current CSR activities in Taiwan are driven by awards, public relations, and external interests. Corporations in Taiwan have the potential to address the health care gaps of urban-rural health utilization among Taiwanese indigenous communities. It is recommended for corporations to (1) develop partnerships with public health experts or to (2) employ CSR personnel with health care backgrounds who can navigate the intersection between health, business, and policies to develop CSR strategies., Conclusions: Further evaluation of the projects mentioned in this paper to assess the direct and indirect impact on health outcomes could provide a more comprehensive understanding of the field of CSR in the health sector in Taiwan.

- Abstract
The purpose of this study is to evaluate patient complaints using the Healthcare Complaints Analysis Tool (HCAT) during the COVID-19 pandemic in 2021 in Taiwan. Additionally, the study examines the distribution and type of patient complaints before and during the COVID-19 pandemic to provide a better clinical procedure, hospital management and patient relationship. This study utilizes a cross-sectional design. We collected patient complaints from January 2021 to December 2021 at a medical center in Southern Taiwan. Using the Healthcare Complaints Analysis Tool (HCAT), the patient complaints are classified and coded into three major domains (clinical, management and relationship), and seven problem categories (quality, safety, environment, institutional process, respect and patient rights, listening and communication). We further compared and categorized the complaints based on whether they were COVID-19-related or not and whether it was before or during the COVID-19 pandemic to understand the differences in patient complaints. In total, we collected 584 events of patient complaints. Based on the HCAT domains, the complaints about management were the highest, at 52.9%, followed by complaints about relationship, about 37.7%. According to the types of problem, the complaints about the environment were the highest, about 32.5% (190/584), followed by communication at about 29.6% (173/584), and institutional process at about 20.4% (119/584). There were 178 COVID-19-related complaints and they were made more frequently during Q3 and Q4 (from mid-June to December) which was the pandemic period in 2021 in Taiwan. Among the COVID-19-related complaints, the most frequent were in the environment domain with 114 cases (about 65.7% of COVID-19-related complaints). The domains of patient complaints were statistically different between COVID-19-related and non-related (p < 0.001). During the COVID-19 pandemic, the proportion of COVID-19-related complaints increased 1.67 times (117/312 vs. 61/272, p < 0.001). Both prior to and during the COVID-19 pandemic, management-related complaints represented the highest domain. During the COVID-19 pandemic, the implementation of infectious disease prevention and control policies and actions may have developed some inconvenience and difficulty in seeking medical practice and process. These characteristics (complaints) are more prominent, and timely and patient-first consideration is required immediately to build up better clinical procedures, the healthcare environment and comprehensive communication. Using the HCAT can allow health centers or health practitioners to understand the needs and demands of patients through complaints, provide friendly medical and health services, avoid unequal information transmission, build trust in doctor−patient relationships and improve patients’ safety.

- Abstract
The aim of this study was to evaluate the association between grip strength, obesity, and cardiometabolic risk factors among elderly individuals with different grip strength statuses and weight statuses in Taiwan. We conducted a series of community-based health surveys among the elderly population in Chiayi County, Taiwan from 2017 to 2019. This is a cross-sectionally designed health check-up program that was conducted by the local public health bureau. Anthropometric characteristics, handgrip strength, diabetes, and cardiometabolic risk profiles were measured using standard methods. This study recruited 3739 subjects (1600 males and 2139 females). The non-obese subjects had lower blood glucose (BG) levels compared to the obese subjects. The BG levels of non-obese and obese subjects were 102.7 ± 25.6 mg/dL vs. 109.1 ± 34.3 mg/dL for males; and 102.8 ± 30.1 mg/dL vs. 112.5 ± 40.3 mg/dL for females (both p < 0.001). The grip strength was negatively associated with BG in both sexes (β = -0.357, p < 0.001 for males and β = -0.385, p < 0.05 for females). The relationship between the grip strength and the risk of diabetes showed that for every 1 kg increase in the grip strength, there was a 4.1% and 4.5% decrease in the risk for developing diabetes for males and females, respectively (OR = 0.959, 95% CI = 0.940-0.979 for males and OR = 0.955, 95% CI = 0.932-0.978 for females). A higher handgrip strength is associated with a lower BG level and a lower risk for diabetes mellitus in the elderly Taiwanese subjects. Additional health promotion should focus on the obese and sarcopenic population to prevent cardiometabolic comorbidities in later life.

- Abstract
Aims: Endoplasmic reticulum (ER) stress is associated with obesity and type 2 diabetes mellitus (T2DM) and increasing evidence demonstrates that some ER stress markers can represent the severity of metabolic dysfunction in either cellular or animal models. However, no appropriate molecule has been identified to demonstrate these relationships in clinical practice., Methods: To determine whether the serum level of the ER chaperone, protein disulfide isomerase family A, member 4 (PDIA4), is associated with type 2 diabetes mellitus, obesity, and insulin sensitivity, we conducted a cross-sectional study for which a total of 553 adults, including 159 with normal glucose tolerance (NGT), 169 with prediabetes (Pre-DM), and 225 with newly diagnosed T2DM, were recruited., Results: Serum PDIA4 levels were significantly higher in patients with T2DM than in those with NGT (P < 0.001), even after adjustment for potential confounders. These levels correlated positively with fasting plasma glucose, BMI, waist circumference as well as high-sensitivity C-reactive protein levels, and negatively and strongly correlated with insulin sensitivity. In a multivariate logistic regression analysis, higher serum PDIA4 concentration was observed to be significantly associated with an increased risk of T2DM., Conclusions: Our findings provide new mechanistic insights linking ER stress, T2DM, insulin sensitivity, and obesity, which may, in part, account for the ER chaperone properties associated with PDIA4. The results suggest that PDIA4 may serve as a potential instigator of and a putative therapeutic target for T2DM., (© 2022. Springer-Verlag Italia S.r.l., part of Springer Nature.)

- Abstract
Background: Patients with diabetes have a relatively high risk of fracture due to osteoporosis. However, the risk of osteoporosis associated with the use of oral hypoglycemic drugs and dipeptidyl peptidase-4 inhibitor (DPP-4i) by patients with diabetes is unclear. This study aimed to explore the effect of DPP-4i on the risk of osteoporosis in Taiwanese patients with type 2 diabetes mellitus (T2DM)., Methods: This study enrolled 6339 patients on DPP-4i (DPP-4i group) and 25 356 patients without DPP-4i (non-DPP-4i group). They were matched by 1:4 propensity score matching, using confounding variables including sex, age, comorbidities, medication, and index year. Cox proportional hazards analysis was used to compare hospitalization and mortality during an average follow-up period of 7 years., Results: The mean age of patients in the two groups was 66 years. Men were slightly higher in number (51.79%) than women. At the end of the follow-up period, 113 (0.36%) patients had osteoporosis, of which 15 (0.24%) were in the case group and 98 (0.39%) in the control group. The risk of all-cause osteoporosis was significantly lower in the DPP-4i group than in the non-DPP-4i group (adjusted hazard ratio [HR] 0.616; 95% confidence interval [CI] 0.358-0.961; p = 0.011). Kaplan-Meier analysis showed that the preventive effect on osteoporosis was positively correlated with the cumulative dose of DPP-4i (log-rank, p = 0.039) with the class effect., Conclusion: Compared with not using DPP-4i, the use of DPP-4i in Taiwanese T2DM patients was associated with a lower risk of osteoporosis due to the class effect, and the preventive effect was dose-dependent. However, larger prospective studies are needed to validate this finding and to explore the possible mechanism of the preventive effect of DPP-4i., Competing Interests: Conflicts of interest: The authors declare that they have no conflicts of interest related to the subject matter or materials discussed in this article., (Copyright © 2022, the Chinese Medical Association.)

- Abstract
Background: Diabetic patients are at high risk of developing cancer. Traditional Chinese medicine (TCM) has become increasingly popular as an adjuvant treatment for patients with chronic diseases, and some studies have identified its beneficial effect in diabetic patients with cancer. The purpoes of this study was to outline the potential of TCM to attenuate hospitalization and mortality rates in diabetic patients with carcinoma in situ (CIS)., Methods: A total of 6,987 diabetic subjects with CIS under TCM therapy were selected from the National Health Insurance Research Database of Taiwan, along with 38,800 of 1:1 sex-, age-, and index year-matched controls without TCM therapy. Cox proportional hazard analysis was conducted to compare hospitalization and mortality rates during an average of 15 years of follow-up., Results: A total of 3,999/1,393 enrolled-subjects (28.62%/9.97%) had hospitalization/mortality, including 1,777/661 in the TCM group (25.43%/9.46%) and 2,222/732 in the control group (31.80%/10.48%). Cox proportional hazard regression analysis showed a lower rate of hospitalization and mortality for subjects in the TCM group (adjusted HR=0.536; 95% CI=0.367-0.780, P <0.001; adjusted HR=0.783; 95% CI=0.574-0.974, P = 0.022). Kaplan-Meier analysis showed that the cumulative risk of hospitalization and mortality in the case and control groups was significantly different (log rank, P <0.001 and P = 0.011, respectively)., Conclusions: Diabetic patients with CIS under TCM therapy were associated with lower hospitalization and mortality rates compared to those without TCM therapy. Thus, TCM application may reduce the burden of national medical resources., (© 2022 Korea Institute of Oriental Medicine. Published by Elsevier B.V.)

- Abstract
The glucokinase regulator gene (GCKR) is located on chromosome 2p23. It plays a crucial role in maintaining plasma glucose homeostasis and metabolic traits. Recently, genome-wide association studies have revealed a positive association between hyperuricemia and GCKR variants in adults. This study investigated this genetic association in Taiwanese adolescents. Data were collected from our previous cross-sectional study (Taipei Children Heart Study). The frequencies of various genotypes (CC, CT, and TT) or alleles (C and T) of the GCKR intronic single-nucleotide polymorphism (SNP) rs780094 and the coding SNP rs1260326 (Pro446Leu, a common 1403C-T transition) were compared between a total of 968 Taiwanese adolescents (473 boys, 495 girls) with hyperuricemia or normal uric acid levels on the basis of gender differences. Logistic and linear regression analyses explored the role of GCKR in abnormal uric acid (UA) levels. Boys had higher UA levels than girls (6.68 ± 1.29 and 5.23 ± 0.95 mg/dl, respectively, p < 0.001). The analysis of both SNPs in girls revealed that the T allele was more likely to appear in patients with hyperuricemia than the C allele. After adjusting for confounders, the odds ratio (OR) for hyperuricemia incidence in the TT genotype was 1.75 (95% confidence interval [CI] 1.02-3.00), which was higher than that in the C allele carriers in rs1260326 in the girl population. Similarly, the TT genotypes had a higher risk of hyperuricemia, with an OR of 2.29 (95% CI 1.11-4.73) for rs1260326 and 2.28 (95% CI 1.09-4.75) for rs780094, than the CC genotype in girl adolescents. The T (Leu446) allele of GCKR rs1260326 polymorphism is associated with higher UA levels in Taiwanese adolescent girls., (© 2022. The Author(s).)

- Abstract
Hypertension is known to be related to obesity and both are the major factors for cardiovascular diseases. The relationship between body composition and blood pressure (BP) are discussed recently. Our study aims to evaluate the association between waist circumference (WC) and appendicular muscle mass (AMM) in relation to BP among the community-dwelling elderly population. Total 3739 patients (1600 males and 2139 females) were recruited in a series of community-based surveys that were conducted among the elderly population in Taiwan from 2017 to 2019. We collected data on anthropometric characteristics, handgrip strength, and BP using standard methods. AMM was calculated with an equation. History of chronic disease and lifestyle profiles were collected using questionnaires. The group with high AMM to body weight ratio (AMMW) showed lower systolic BP (SBP) (136.8 ± 19.1 to 140.6 ± 17.0 for males; 137.8 ± 18.3 to 142.7 ± 17.5 for females, both P < .001). Among central obese persons those with higher AMMW ratio had lower SBP. In the final model, AMMW in percentage is negatively associated to SBP (β = -0.641 in male, -0.780 in female, both P < .01). In other words, every 10% increase in AMMW is associated with decrease of SBP 6.41 mmHg in male and 7.80 mmHg in female. Obesity and central obesity were positively associated with BP. The AMMW ratio was negatively associated with HTN and with a protective effect on BP even among the central obese. Health promotion programs to increase physical training may prevent hypertension among the elderly in Taiwan., (© 2022 The Authors.

- Abstract
Objectives: We sought to investigate the effects of time-restricted feeding (TRF) and a traditional weight-loss method on body composition and cardio-metabolic risk factors in middle-aged women., Methods: In a single-center, randomized, open-label, parallel-group design, women ages 40 to 65 y with body mass index ≥ 24 kg/m
2 or waist circumference > 80 cm were recruited. They were guided to a daily low-calorie diet of 1400 kcal and randomly assigned into a TRF group (limit 8 h of eating time and fasting for 16 h) or a non-TRF group (traditional weight-loss method, unrestricted eating time) for 8 wk. Body composition, blood pressure, blood biochemical variables, and insulin resistance status were measured before and after intervention., Results: Body weight, body mass index, waist circumference, and body fat mass decreased significantly in both groups after 8 wk of intervention (P < 0.05). Body weight decreased more in the TRF group than the non-TRF group (-4.1% ± 2.8% versus -2.4% ± 2.5%; P = 0.012), as did diastolic blood pressure (75.3 ± 11.2 mm Hg versus 70.5 ± 9.4 mm Hg; P = 0.012). There were no statistical differences between the two groups in total cholesterol, triacylglycerols, high- or low-density lipoprotein cholesterol, and fasting insulin level. However, fasting glucose and insulin resistance status increased significantly for the TRF group after the intervention (respectively, 88.3 ± 7.6 mg/dL versus 92.6 ± 9.6 mg/dL, P = 0.003; 1.7 ± 0.7 versus 2.1 ± 1.0, P = 0.048)., Conclusion: The weight loss and reduction in diastolic blood pressure using the TRF method were better than with the traditional weight-loss method. However, this method may increase fasting glucose levels and adverse insulin resistance status., (Copyright © 2021 Elsevier Inc. All rights reserved.)- Published

- Abstract
Background: Numerous studies have shown that dipeptidyl peptidase-4 inhibitors (DPP-4i) may regulate immunological pathways implicated in asthma. The association between DPP-4i use and risk of asthma development is limited, however., Aim: We aimed to evaluate if DPP-4i treatment in individuals with type 2 diabetes mellitus (T2DM) is associated with a lower risk and severity of asthma., Methods: We performed a population-based retrospective cohort study using the Longitudinal National Health Insurance Research database between 2008 and 2015. After one-to-four propensity score matching from 1,914,201 patients with defined criteria, we enrolled 3001 patients who were on DPP-4i (DPP-4i group) for a diagnosis of T2DM but without a diagnosis of asthma for further analysis. Cox proportional hazards regression analysis was performed to estimate and compare the risk of developing and severity of asthma, including no acute exacerbations event (No-AE), acute exacerbations (AEs), status asthmaticus (Status), and required endotracheal intubation (ET-tube intubated), between the two groups., Results: The participants had a mean age of 66.05 ± 17.23 years and the mean follow-up time was 4.96 ± 4.39 years. The risk of asthma development was significantly lower in the DPP-4i group than in the non-DPP-4i group [adjusted hazard ratio (HR) = 0.65; 95% confidence interval (CI) = 0.29-0.83; p < 0.001], with a class effect. This trend was observed for severity of asthma as No-AE (HR = 0.55; 95% CI = 0.24-0.70; p < 0.001), AE (HR = 0.57; 95% CI = 0.26-0.73; p < 0.001), and Status (HR = 0.78; 95% CI = 0.35-0.99; p = 0.047), but not in ET-tube intubated cases (HR = 0.96; 95% CI = 0.43-1.22; p = 0.258)., Conclusion: The use of DPP-4i decreased the risk and severity of asthma with a class effect among No-AE, AE, status of asthma events, but not in ET-tube intubated events. Our report suggests that DPP-4i may play a role in attenuating the impact of asthma on incidence in the future and on more severe forms of disease exacerbation in T2DM patients.

- Abstract
Objectives: Frailty is a significant public health and clinical issue among the elder population. This study aimed to evaluate the nutritional status and renal function in relation to frailty among elderly Taiwanese., Design: We administered community-based health surveys to the elder population in Chiayi County, Taiwan, from 2017 to 2019., Measurements: We measured nutritional status (including serum albumin and total protein levels), renal function (including serum blood urea nitrogen, creatinine, urine protein, and urine creatinine levels), hand grip strength (GS) and calculated appendicular muscle mass (AMM)., Results: The study recruited 3739 participants (2139 women). Participants of both sexes with normal GS had higher serum albumin levels and lower urine protein/creatinine ratios (UPCRs). For the men with normal and weak GS, serum albumin levels were 4.15 ± 0.2 and 4.10 ± 0.2 g/dL (p < 0.01), and UPCRs were 123.1 ± 219.6 and 188.7 ± 366.2 (p < 0.001), respectively. GS was positively correlated with serum albumin and urine creatinine levels (r = 0.136 and 0.177, both p < 0.001). AMM was also positively correlated with serum albumin and urine creatinine levels (r = 0.078 and 0.091, both p < 0.001). In the multivariate regression model, for every 1 g/dL increase in serum albumin level, there was a 1.9 and 1.7-kg increase in GS for men and women (p < 0.05 and p < 0.01), respectively. The final model for predicting GS included age, albumin, BUN, and UPCR (urine creatinine for women) which presented a variance of 22.1% and 13.8%, respectively., Conclusion: Proper dietary nutritional intake and maintaining renal function are key elements for preventing frailty among elder population in Taiwan., Competing Interests: No potential conflict of interest relevant to this article was reported.

Background: Sarcopenia and muscle weakness in elderly are contributed burden of public health and impact on quality of life. Weak grip strength was key role in diagnosis of sarcopenia and reported increased mortality, function declined in elderly. This study evaluated the association between GS and each common anthropometric characteristic in community-dwelling elderly., Design and Method: From 2017 to 2019, we conducted a community-based health survey among the elderly in Chiayi county, Taiwan. Participants were 65 years old or older, and total of 3,739 elderly subjects (1,600 males and 2,139 females) with a mean age of 76 years (range 65-85 years old) were recruited. General demographic data and lifestyle patterns were measured using a standard questionnaire. Anthropometric characteristics such as body height, body weight, body mass index (BMI), body waist and hip circumference, and body fat were measured by standard methods. GS was measured using a digital dynamometers (TKK5101) method., Results: The mean GS was 32.8 ± 7.1 kg for males and 21.6 ± 4.8 kg for females (p < 0.001). For both sexes, elderly subjects with the same body weight but smaller body waist circumference had greater GS. The subjects with the same body waist size but heavier weight had greater GS. Furthermore, after adjusting for age, lifestyles, disease status, and potential anthropometric variable, multivariate regression analyses indicated that BMI was positively associated with GS (for males, beta = 0.310 and for females beta = 0.143, both p < 0.001) and body waist was negatively associated with GS (for males, beta = -0.108, p < 0.001; for females, beta = -0.030, p = 0.061)., Conclusions: This study suggested that old adults with higher waist circumstance had weaker GS. Waist circumstance was negatively associated with GS, body weight was positively associated with GS in contrast. It may implies that central obesity was more important than overweight for GS in elderly., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background : The combination of multiple disease statuses, muscle weakness, and sarcopenia among older adults is an important public health concern, and a health burden worldwide. This study evaluates the association between chronic disease statuses, obesity, and grip strength (GS) among older adults in Taiwan. Methods : A community-based survey was conducted every 3 years among older adults over age 65, living in Chiayi County, Taiwan. Demographic data and several diseases statuses, such as diabetes mellitus, hypertension, cerebrovascular disease, cardiovascular disease, and certain cancers, were collected using a questionnaire. Anthropometric characteristics were measured using standard methods. Grip strength was measured using a digital dynamometer (TKK5101) method. Results : A total of 3739 older individuals were recruited (1600 males and 2139 females) with the mean age of 72.9 years. The mean GS was 32.8 ± 7.1 kg for males and 21.6 ± 4.8 kg for females. GS significantly decreased most in males with cerebrovascular disease (from 33.0-29.5 kg, p < 0.001) and in females with diabetes mellitus (from 21.8-21.0 kg, p < 0.01). GS was highest in older adults with obesity (body mass index ≥ 27 kg/m
2 ); however, there was no significant change of GS as the disease number increased. Conclusion : Older adults who have two, rather than one or greater than three chronic diseases, have significantly lower GSs than those who are healthy. Stroke and CKD for males, and hypertension and diabetes for females, are important chronic diseases that are significantly associated with GS. Furthermore, being overweight may be a protective factor for GS in older adults of both sexes.- Published

- Abstract
Obesity has been steadily rising in the last few decades and to some extent, have been linked to exposure of adverse childhood experiences (ACEs). ACEs are intense stressors or traumatic events experienced or witnessed by children, ranging from all types of abuse (physical, emotional, and sexual), neglect, substance abuse or community violence. These traumatic events deprive the sense of safety and stability of a child, leaving psychological and physiological effects that span into adulthood. The prevalence of ACEs is common across developed and developing countries alike, though the rates differ across ethnicities. Using the United States as an example, the prevalence of ACEs experienced by communities of color is higher than white children. Children around the world could all be exposed to ACEs, hence the original questionnaire capturing the score of ACE has been adapted to different cultural situations. The mechanism linking ACEs to obesity during adulthood include biological, psychological, and environmental factors. Nevertheless, a higher ACE score heightens the risk of poor mental health, attempted suicide and development of obesity and diabetes in adulthood. Prevention of ACEs starts from building positive relationships within families, developing healthy relationship skills, and screening of ACEs during early and routine pediatrician's and primary care visits. Intervention needs to include case management services and psychosocial support programs. When these risk factors are intervened early, it lessens the risk of obesity and diabetes in adulthood., (Copyright © 2021 Asia Oceania Association for the Study of Obesity.

- Abstract
Abstract: Irisin, a novel myokine, is believed to be the crucial factor in converting white adipose tissue to beige adipose tissue. For this paper, we studied the relationship among irisin and components of metabolic syndrome (MetS), and insulin secretion and resistance in schoolchildren of Taiwan.Subjects receiving routine annual health examination at elementary school were enrolled. Demographic data, anthropometry, MetS components, irisin, and insulin secretion and resistance were collected. Subjects were divided into normal, overweight, and obese groups for evaluation of irisin in obesity. Finally, the relationship between irisin and MetS was analyzed.There were 376 children (179 boys and 197 girls), aged 10.3 ± 1.5 years, were enrolled. In boys, irisin levels were not associated with body mass index percentile, body fat, blood pressure, lipid profiles, insulin secretion or resistance. After adjusting for age, the irisin level in boys was negatively related to fasting plasma glucose (FPG) (r = -0.21, P = .006). In girls, after adjusting for age, the irisin levels were positively related only to FPG (r = 1.49, P = .038). In both genders, irisin levels were similar among normal, overweight, and obese groups, and between subjects with and without MetS.The irisin levels were not associated with MetS in either boys or girls. In girls, circulating irisin levels have a nonsignificant declining trend in overweight and obese girls. However, irisin levels were negatively related to FPG in boys and positively related to FPG in girls. The contrary relationship between irisin and FPG in boys and girls needs further exploration., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 the Author(s).

- Abstract
It remains unclear how different uses of angiotensin-converting inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) influence the progression of chronic kidney disease (CKD). This study explored CKD progression in a multicentre, longitudinal cohort study that included 2639 patients with CKD stage 1-5 and hypertension. Patients treated with ACEI or ARB for ≥90 days during a 6-mo period comprised the study group, or no treatment, comprised the control group. The study group was subdivided on the basis of treatment: ACEI monotherapy or ARB monotherapy. Progression of renal deterioration was defined by an average eGFR decline of more than 5 mL/min/1.73 m
2 /yr or the commencement of dialysis. With at least 1-year follow up, a progression of renal deterioration was demonstrated in 29.70% of the control group and 25.09% of the study group. Patients in the study group had significantly reduced progression of CKD with adjusted odds ratio 0.79 (95% confidence interval: 0.63-0.99). However, when ACEI monotherapy and ARB monotherapy were analyzed separately, none of their associations with CKD progression was statistically significant. In conclusion, ACEI or ARB monotherapy may retard the deterioration of renal function among patients with CKD and hypertension.- Published

- Abstract
This study investigated the characteristics of patients with different chronic kidney disease (CKD) stages according to various body mass index (BMI) categories and determined the influence of BMI in renal function deterioration. We conducted a multicenter, longitudinal cohort study based on the Epidemiology and Risk Factors Surveillance of CKD project (2008-2013) and National Health Insurance Research Database (2001-2013). A total of 7357 patients with CKD aged 20-85 years from 14 hospitals were included in the study. A higher male sex, diabetes mellitus (DM) and hypertension were noted among overweight and obese CKD patients, while more cancer prevalence was noted among underweight CKD patients. Charlson comorbidity index was significantly higher and correlated with BMI among late CKD patients. Patients with BMI < 18.5 kg/m
2 exhibited non-significantly higher events of eGFR decline events in both early and late CKD stages than other BMI groups. BMI alone is not a determinant of CKD progression among our Taiwanese CKD patients. Obesity should be re-defined and body weight manipulation should be individualized in CKD patients.- Published

- Abstract
Adropin is a 76 amino acid peptide hormone with a molecular weight of 4999.9Da that may be associated with energy homeostasis, insulin resistance and lipid metabolism in mice and human. There is only a few studies that examine plasma adropin levels and body composition in children. This study is to evaluate the relationship between plasma adropin levels, body composition and lipid variables amongst young adolescents in Taiwan. We examined 492 adolescents (269 females and 223 males) ranging from 12 to 15 years old, with a mean age of 13.6 years. Body composition was measured using impedance method by Tanita-BC418. Plasma lipid variables were measured using standard methods and plasma adropin levels were measured using the ELISA method. There was no significant difference in plasma adropin levels between males and females (3.52 vs. 3.58ng/ml). Plasma adropin levels were negatively correlated with fat free mass (r=-0.12, p<0.01). More interestingly, children with higher plasma adropin levels had lower waist-to-hip ratios (WHR) and lower body fat percentage by mass. Furthermore, there is no difference in lipid profiles in high vs. low adropin subjects. Plasma adropin levels are not consistency associated with body composition and no association with lipid variables amongst Taiwanese adolescents. The role of adropin in the development of obesity is still not clear, and further studies are need especially for children., (Copyright © 2017 Asia Oceania Association for the Study of Obesity.

- Abstract
Objectives: The purpose of this study is to evaluate the prevalence and trends of cigarette smoking among young military conscripts, military officers, and military university students during recently 10 years in Taiwan., Methods: Repeated cross-sectional surveys were conducted annually among young military conscripts and military university students from 2006 to 2014. All the young conscripts were reviewed within 1 month at the military training center and before retiring after 1 year of military services. The military officers were included using purposive sampling from 2004 to 2008 and 2013 to 2014 in different military services. Military university students were included in this study. Freshman and senior students were random sampled as the study subjects. Participants completed a structured questionnaire that included questions on general demographics and health-related behaviors. Current smokers is defined as subjects who smoked ≥1 cigarette/day during the past 30 days or had smoked ≥100 cigarettes in their lifetime or still have the habit of smoking during study. We used a χ
2 test to examine the difference between the prevalence of cigarette smoking among different groups. The Cochran-Armitage test for trend was applied to examine the change of prevalence of smoking after repeated cross-sectional surveys among populations., Results: The prevalence of cigarette smoking within military training center and after 1-year military services was 48.6% and 48.1% on 2006, which became 39.2% and 38.6% on 2010, and then further declined to 31.0% and 30.1% on 2014. For military officers, the trends of prevalence of smoking among different military services showed slight decline from 2004 to 2008, but decreased significantly between 2013 and 2014. The prevalence of smoking in 2014 was 32.1%, 32.8%, and 32.4% for the Army, Navy, and Air Force, respectively. More interestingly, the prevalence of smoking of freshman and senior students increased during the first 5 years (2007-2011) of survey and then decreased after 2012. Furthermore, in 2014, the prevalence of smoking decreased as the difference became smaller, 4.5% and 6.1% for freshman and senior, respectively., Conclusion: During this 10-year period, the smoking cessation programs include in-class education course, out-door physical training, antismoking clinic, and group therapy. After these military health promoting programs, there are some beneficial effects to decline the prevalence of cigarette smoking for military personnel in Taiwan. However, more active intervention and health promoting programs in prevention and cessation of smoking are needed for the military. The military also have to develop specific approaches and programs to prevent cigarette smoking among conscripts and officers., (Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.)- Published

- Abstract
Background: Morbid obesity is related to chronic inflammation and many metabolic complications. Interleukin (IL)-6 plays a pivotal pathophysiological role in obesity, and IL-6 trans-signaling through the soluble IL-6 receptor (sIL-6R) has a major proinflammatory effect. The aim of this study was to investigate the association between sIL-6R, adipocyte size, and insulin resistance in morbidly obese individuals., Methods: We measured concentrations of sIL-6R, high-sensitivity C-reactive protein, and lipid parameters and estimated homeostasis model assessment of insulin resistance (HOMA-IR) before the patients underwent bariatric surgery. Mesenteric adipose tissue was collected during surgery, and adipocyte size and concentrations of membrane-bound IL-6 receptor (mIL-6R) were evaluated. In total, 35 adults (20 men and 15 women) were recruited., Results: The subjects with high HOMA-IR (≥2.4) had higher fasting glucose/insulin, triglycerides, sIL-6R, and adipocyte size and lower high-density lipoprotein cholesterol and mIL-6R than those with low HOMA-IR (<2.4). Adipocyte size positively correlated with sIL-6R (r = 0.559, P = 0.001) and HOMA-IR (r = 0.773, P ≤ 0.001) independent of age, gender, body mass index (BMI), waist, and use of diabetic drugs. In addition, every 1 ng/mL increase in sIL-6R concentration corresponded to a 10.2% decrease in the likelihood of maintaining lower insulin resistance. Furthermore, an sIL-6R level of 77.45 ng/mL was a reasonable cutoff level to propose lower insulin resistance in morbidly obese subjects., Conclusions: Circulating sIL-6R is more closely associated with insulin resistance status than waist-to-hip ratio or BMI in morbidly obese Taiwanese adults. sIL-6R may be a useful biomarker to assess insulin resistance among morbidly obese subjects.

- Abstract
Background: To investigate the risk factors associated with cardiovascular diseases and its relation to BMI, body fat mass and plasma leptin level among adolescents in Taitung, Taiwan., Methods: A cross-sectional Taitung Children Heart Study for 500 young adolescents between ages 13 and 15 was conducted. Gender-specific regression models were used to determine the associations between BMI, percentage of body fat mass, plasma leptin level and seven CVDs risk factors (systolic and diastolic blood pressure, mean arterial pressure, triglycerides, total cholesterol, HDL-cholesterol and LDL-cholesterol) before and after adjusting for weight status and age., Results: After adjusting for weight status and age, BMI was positively associated with systolic BP, triglycerides, LDL-cholesterol levels but negatively associated with HDL-cholesterol level in boys while positively associated with systolic and diastolic BP, mean arterial pressure, and LDL-cholesterol level in girls. The percentage of body fat mass was positively associated with triglycerides, total cholesterol, and LDL-cholesterol in boys while positively associated with systolic BP, total cholesterol, and LDL-cholesterol in girls. Plasma leptin was positively associated with triglycerides, total cholesterol and LDL-cholesterol in boys but no statistically significant associations with CVDs risk factors in girls. A strong relationship between the percentage of body fat mass and plasma leptin appeared among all participants (r=0.59, p<0.01)., Conclusions: BMI, body fat mass and plasma leptin level may be used to identify certain CVDs risk factors among Taitung adolescents. Future researches could consider measuring body fat mass in the relationship of CVDs risk factors instead of plasma leptin among young adolescents., (Copyright © 2015 Asia Oceania Association for the Study of Obesity.

- Abstract
Aims: Variants of the glucokinase regulator (GCKR) gene are associated with metabolic syndrome (MetS). The present study explored the association between a common variant of this gene and MetS and its related traits in Taiwanese adolescents., Methods: The frequency of MetS and its features were compared between subjects (n = 962; 468 male, 494 female) with different genotypes or alleles of the GCKR rs780094 single-nucleotide polymorphism. Logistic regression analysis was carried out to explore the interdependence of MetS and metabolic traits., Results: Low high-density lipoprotein cholesterol (HDL-C) levels and MetS were more prevalent in subjects with the T compared to the C allele of rs780094 (p = 0.009 and 0.044, respectively). T-genotype carriers also exhibited a higher frequency of low HDL-C levels (p = 0.028) than noncarriers, although MetS frequency was similar between the two groups. After adjusting for confounding factors, the odds ratios for low HDL-C levels and MetS incidence in T-genotype carriers were 1.64 (95% confidence interval [CI]: 1.07-2.53) and 2.79 (95% CI: 1.09-7.11), respectively., Conclusions: The GCKR rs780094 polymorphism is associated with low HDL-C levels and MetS incidence in Taiwanese adolescents.

- Abstract
Objectives: Soluble urokinase plasminogen activator receptor (suPAR), derived from membrane bound uPAR, is associated with inflammatory diseases. In the present study, we explored the expression of uPAR/suPAR in common biopsy-proven kidney diseases and the relationship between suPAR and staging of type 2 diabetic nephropathy (DN)., Design and Methods: Serum samples for suPAR and renal tissues for uPAR staining were investigated in various common kidney diseases. The levels of serum suPAR were measured and adequate cut-off values of different stage of DN were calculated by receiver operating characteristic (ROC) curve., Results: In our results, the expression of uPAR on renal tissues was pronounced in the majority of kidney diseases. Comparing of expression of uPAR among different kidney diseases, it was strongest in minimal change disease (MCD) and weakest in chronic interstitial nephritis. Serum suPAR in most kidney diseases, except of MCD, was significantly elevated and was highest in DN. As for DN and suPAR, we found that suPAR progressively increased with staging of DN. Moreover, suPAR was linearly and negatively related to estimated glomerular filtration rate and positively related to the amount of proteinuria. By ROC curve, the cut-off values of suPAR in DN for assessing development increased with the progression of the disease., Conclusions: We concluded that uPAR/suPAR is elevated in most kidney diseases and that suPAR is a useful biomarker for assessing stages of DN., (Copyright © 2015 The Canadian Society of Clinical Chemists.

- Abstract
Auricular acupoint stimulation has become a popular weight loss method. However, its efficacy for obesity treatment has not been fully studied. This study aimed to investigate the effect of a 10-week intervention of auricular electrical stimulation combined with auricular acupressure on weight reduction in obese outpatients. In this single-blind randomized sham-controlled study, 134 participants were randomly assigned to an experimental group receiving stimulation at true acupoints, or a sham group receiving stimulation delivered in the same manner but at sham acupoints. Each participant received nutrition counseling by a nutritionist weekly. The results showed significant differences in body mass index, blood pressure, total cholesterol, triglyceride, and leptin or adiponectin over time within the group, but not between the groups. This study could not exclude the effect of placebo and dietary consultation. Further study that adds a control group receiving no treatment is therefore needed to confirm the effects of auricular acupressure., (© The Author(s) 2014.)

- Abstract
Aims and Objectives: To develop a descriptive theory for the weight loss experiences of obese perimenopausal women with metabolic syndrome., Background: Obesity and metabolic syndrome both pose a threat to the health of perimenopausal women; therefore, understanding perimenopausal women's subjective feelings and experiences is beneficial to establishing effective prevention strategies. However, studies have rarely explored these relevant experiences., Design: A qualitative study using the grounded theory method to establish a descriptive theory., Methods: Eighteen obese perimenopausal women with metabolic syndrome aged 45-60 years participated in comprehensive interviews., Results: 'Crossing the gaps to making life modifications' was the core category, and 'the awareness of weight gain and health alarm' was the antecedent condition. In the weight loss experience, the following three interaction categories were identified: (1) 'experiencing bad feelings,' (2) 'encountering obstacles' and (3) 'making efforts to transition to a new life.' Some women adhered to new life habits through perceiving social support and by using self-incentives. Finally, women enjoyed and mastered self-monitoring of their health in their new life, and practiced new changes as part of their life. However, some participants felt that making changes to their life was too time-consuming. Therefore, these women chose to live with their abnormal health without making changes., Conclusions: Obese perimenopausal women with metabolic syndrome experienced various gaps in their weight loss process. Although they struggled with many obstacles, these women were able to learn from their experiences and face their health challenges., Relevance to Clinical Practice: These findings can guide healthcare professionals to provide appropriate interventions to understand the hidden health problems of this particular group of women. Healthcare professionals should develop a set of plans by which women receive a complete weight loss program and support from professionals and family., (© 2015 John Wiley & Sons Ltd.)

- Abstract
Overweight and obesity are serious public health and medical problems among children and adults worldwide. Behavioural change has been demonstrably contributory to weight management programs. Behavioural change-based weight loss programs require a theoretical framework. We will review the transtheoretical model and the organisational development theory in weight management. The transtheoretical model is a behaviour theory of individual level frequently used for weight management programs. The organisational development theory is a more complicated behaviour theory that applies to behavioural change on the system level. Both of these two theories have their respective strengths and weaknesses. In this manuscript, we try to introduce the transtheoretical model and the organisational development theory in the context of weight loss programs among population that are overweight or obese. Ultimately, we wish to present a new framework/strategy of weight management by integrating these two theories together., (Copyright © 2015 Asian Oceanian Association for the Study of Obesity.

- Abstract
We investigated the role of urokinase plasminogen activator (uPA) and its soluble receptors (suPAR) and plasminogen activator inhibitor-1 (PAI-1) in metabolic syndrome (MetS) components, insulin secretion, and resistance in schoolchildren. We enrolled 387 children, aged 10.3 ± 1.5 years, in Taipei. Anthropometry, fibrinolytic proteins, MetS components, insulin secretion, and resistance were measured. Subjects were divided into normal, overweight, and obese groups. Finally, the relationship between fibrinolytic proteins and metabolic syndrome in boys and girls was analyzed. In boys, PAI-1 was positively associated with body mass index (BMI) percentile, hypertriglyceride, insulin secretion, and resistance. In girls, PAI-1 was positively associated with obesity, hypertriglyceridemia, and insulin secretion. In girls, uPA was positively associated with insulin secretion. suPAR was positively associated with high-sensitivity C-reactive protein in both boys and girls, and with BMI percentile and body fat in girls. The obese boys had higher suPAR and PAI-1 levels than the normal group. The obese girls had higher uPA, suPAR, and PAI-1 than the normal group. Boys and girls with MetS had higher PAI-1. Fibrinolytic proteins, especially PAI-1, are associated with MetS components and insulin secretion in children. Fibrinolytic proteins changes were more likely to occur in girls than in boys.

- Abstract
Aims and Objectives: To explore health literacy status in asthma patients and to examine the causal model linking health literacy to health outcome-related factors via mediator and moderator variables., Background: Understanding how low health literacy may influence health outcomes is important., Design: This is a cross-sectional survey study., Methods: A total of 326 asthma patients aged 20 years and older (average: 51 ± 18·3 years) were recruited by purposive sampling from pulmonary medicine outpatient departments at three medical centres and a regional teaching hospital in northern Taiwan. Data were collected via structured questionnaires, including measures of socio-demographic and disease characteristics; medical decision-making; asthma knowledge, attitudes and self-efficacy; healthcare experience and health outcome-related factors (metered-dose inhaler/dry-powder inhaler usage proficiency, medical use, self-management behaviour). Three hundred patients who met the inclusion criteria and completed the questionnaire survey were analysed., Results: Overall, 217 subjects (72·3%) had adequate functional health literacy, 42 (14%) had inadequate functional health literacy, and 41 (13·7%) had marginal functional health literacy. Subjects' average asthma knowledge, attitudes and self-efficacy scores were 7·23 ± 2·69, 51·46 ± 6·18 and 58·31 ± 8·10, respectively. Health literacy correlated positively with asthma knowledge (r = 0·605), attitudes (r = 0·192) and medical decision-making (r = 0·413)., Conclusions: Health literacy is positively associated with proficiency in metered-dose inhaler usage, asthma knowledge, attitudes and medical decision-making, but is not significantly associated with medical care use and self-management behaviour. Health literacy had an indirect effect on self-management behaviour through the mediation effect of asthma attitudes. No moderator was found for the effect of health literacy on health outcome-related factors., Relevance to Clinical Practice: Results of this study may help to develop adequate intervention strategies to improve the health outcomes of asthma patients., (© 2013 John Wiley & Sons Ltd.)

- Abstract
Background: Smoking, a self-selected behavior, is the sixth leading cause of death worldwide. Factors related to smoking in Taiwan's indigenous Malayo-Polynesian population should be elicited and addressed., Purpose: This study examined the relationship between smoking behavior and individual and family/community factors in indigenous Taiwanese., Methods: This study was a secondary analysis of data obtained from household visits in central Taiwan that included a population of 562 indigenous adults aged 20-50 years. Data were analyzed using the chi-square test and hierarchical logistic regression to determine individual and family/community relevant factors of smoking behaviors., Results: The smoking rate in the population studied was 57.48% (39.15% men, 18.33% women). The odds ratio for smoking was markedly higher in men than in women. Smokers were 0.45 times more likely to have fixed sexual partners. The OR for smoking was 2.68 times in households with smokers and 7.03 times in people living in mountainous areas., Conclusions: The issue of smoking in indigenous Taiwanese deserves further attention and concern. Further interventions for the harmful effects of tobacco can focus on younger indigenous people living in mountain regions and on smokers' sexual partners. In addition, male adults, female adults, and heads of households should take a greater role in changing the smoking behaviors of smokers and their family members.

- Abstract
Objectives: To evaluate the trend of dyslipidaemia from 1996 to 2006 and examine its relationship with weight status among adolescents in Taiwan., Design: 2 cross-sectional surveys were conducted in 1996 and 2006., Setting: The junior high schools in Taipei., Participants: After multistage sampling, total of 1500 and 1283 junior high school students were chosen in 1996 and 2006. After excluding missing data, a total of 1353 (676 boys and 677 girls) and 1203 (585 boys and 618 girls) children were included in the final analyses in 1996 and 2006., Outcome Measures: Anthropometric measures as body height and weight were measured, and body mass index (BMI) was calculated. Blood lipid profiles as total cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol were measured., Results: From 1996 to 2006, the prevalence of dyslipidaemia and hypercholesterolaemia significantly increased from 13% (95% CI 11.3% to 15.0%) to 22.3% (95% CI 20.0% to 24.7%) and 6.2% (95% CI 5.0% to 7.6%) to 13.8% (95% CI 11.9% to 15.9%), respectively. The prevalence of hypertriglyceridaemia and low HDL-C dyslipidaemia increased from 3% (95% CI 1.8% to 4.5%) to 4.3% (95% CI 2.8% to 6.2%) and 6.5% (95% CI 4.8% to 8.6%) to 11.6% (95% CI 9.1% to 14.5%), with significance seen only in boys. When compared with normal weight participants, overweight boys and girls faced a 2-fold and 1.6-fold increased risk of dyslipidaemia, respectively, in the 2006 study. The increased risk of low HDL-C dyslipidaemia for overweight participants was 2.6-fold and 7.2-fold in boys and girls, respectively. In 2006, each unit increment of BMI was associated with 28%, 13% and 13% risk of hypertriglyceridaemia, low HDL-C and dyslipidaemia for boys, and 25% risk of low HDL-C dyslipidaemia in girls., Conclusions: The prevalence of dyslipidaemia had increased significantly for boys and girls in normal weight and overweight adolescents. Early screening of dyslipidaemia and weight intervention programmes in adolescents will be the key to prevent dyslipidaemia and cardiovascular-related comorbidities.

- Abstract
Gilbert's syndrome is suspected in patients with unconjugated hyperbilirubinemia caused by decreased activity of the UDP-glucuronosyltransferase 1A1 (UGT1A1) gene in the absence of abnormal liver function and hemolysis. The major genetic variants underlying Gilbert's syndrome are TATA-box repeats of the promoter region and exon 1 G211A of the coding region, particularly in Asians. The efficacy of DNA melting curve analysis, however, has not been established for the G211A mutation. For rapid and accurate molecular diagnosis of Gilbert's syndrome, DNA melting curve analysis was evaluated for its genotyping capability not only for TATA-box repeats of the UGT1A1 promoter, but also for G211A of UGT1A1 exon 1. TA repeats within the TATA-box sequence and the exon 1 G211A mutation of the UGT1A1 gene were analyzed by DNA melting curve analysis. To evaluate the assay reliability, direct sequencing or polyacrylamide gel electrophoresis was used as a comparative method. All homozygous and heterozygous polymorphisms of A(TA)7TAA within the TATA-box allele and of exon 1 G211A mutants of the UGT1A1 gene were successfully identified with DNA melting curve analysis. DNA melting curve analysis is, therefore, an effective molecular method for the rapid diagnosis of Gilbert's syndrome, as it detects not only TATA-box polymorphisms but also the exon 1 G211A mutation located within the UGT1A1 gene.

- Abstract
The present study was designed to explore the effects of GAS6 and AXL gene polymorphisms on adiposity, systemic inflammation, and insulin resistance in adolescents. After multistage sampling from the data of the Taipei Children Heart Study-III, we collected 358 boys and 369 girls with an average age of 13.3 years. We genotyped the adolescents' GAS6 rs8191973, GAS6 rs8191974, AXL rs4802113, and AXL rs2304232 polymorphisms. Significantly higher body mass index (BMI), waist circumference (WC), and hsCRP levels were found in boys with the GG genotype of GAS6 rs8191974 than A allele carriers; higher IL-6 and insulin levels and increased HOMA-IR were found in boys with the GG genotype of AXL rs2304232 than the A allele carriers. There was a significant difference in hsCRP levels of boys with the TT, TC, and CC genotypes of AXL rs4802113. Boys with both the GG genotype of GAS6 rs8191973 and the GG genotype of GAS6 rs8191974 exhibited higher BMI, WC, IL-6, and hsCRP levels than the boys carrying both the C allele of the GAS6 rs8191973 and the A allele of the GAS6 rs8191974. In conclusion, GAS6 and AXL polymorphisms are associated with adiposity, systemic inflammation, and insulin resistance in adolescents, especially in boys.

- Abstract
The aim of this cross-sectional study was to investigate the relationship between soluble form of receptor for advanced glycation end products (sRAGE), obesity, and metabolic syndrome (MetS) in adolescents. A total of 522 male and 561 female adolescents were enrolled into the final analyses. Anthropometric parameters, blood pressure, blood biochemistry, fasting insulin, and plasma sRAGE levels were measured. In males, sRAGE was significantly and inversely correlated with waist circumference (WC), body mass index (BMI), systolic blood pressure, triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and homeostasis model assessment-insulin resistance (HOMA-IR). Only WC and BMI were significantly and inversely correlated with sRAGE in females. Using linear regression analysis adjusting for age and gender, significant association was found between sRAGE and WC, BMI, TG, LDL-C, and HOMA-IR in adolescents of either gender (P < 0.05). This association was abolished when further adjusting BMI. In addition, sRAGE was significantly and inversely correlated with the increasing number of components of MetS in males (P for trend = 0.006) but not in females (P for trend = 0.422). In conclusion, plasma sRAGE is associated with obesity and MetS among adolescents. BMI may be the most important determinant of sRAGE levels in adolescents.

- Abstract
Background: Although the genetic basis of androgenic alopecia has been clearly established, little is known about its non-genetic causes, such as environmental and lifestyle factors., Objective: This study investigated blood and urine heavy metals concentrations, environmental exposure factors, personal behaviors, dietary intakes and the genotypes of related susceptibility genes in patients with androgenic alopecia (AGA)., Design: Age, AGA level, residence area, work hours, sleep patterns, cigarette usage, alcohol consumption, betel nut usage, hair treatments, eating habits, body heavy metals concentrations and rs1998076, rs913063, rs1160312 and rs201571 SNP genotype data were collected from 354 men. Logistic regression analysis was performed to examine whether any of the factors displayed odds ratios (ORs) indicating association with moderate to severe AGA (≥ IV). Subsequently, Hosmer-Lemeshow, Nagelkerke R(2) and accuracy tests were conducted to help establish an optimal model., Results: Moderate to severe AGA was associated with the AA genotype of rs1160312 (22.50, 95% CI 3.99-126.83), blood vanadium concentration (0.02, 95% CI 0.01-0.04), and regular consumption of soy bean drinks (0.23, 95% CI 0.06-0.85), after adjustment for age. The results were corroborated by the Hosmer-Lemeshow test (P = 0.73), Nagelkerke R(2) (0.59), accuracy test (0.816) and area under the curve (AUC; 0.90, 0.847-0.951) analysis., Conclusions: Blood vanadium and frequent soy bean drink consumption may provide protect effects against AGA. Accordingly, blood vanadium concentrations, the AA genotype of rs1160312 and frequent consumption of soy bean drinks are associated with AGA.

- Abstract
Context: Growth arrest-specific 6 (Gas6) is a vitamin K-dependent protein secreted by immune cells, endothelial cells, vascular smooth muscle cells, and adipocytes. Preclinical studies indicate that Gas6 and its receptors of the TAM (Tyro-3, Axl, Mer) family may be involved in the pathogenesis of obesity and its complications, including systemic inflammation and insulin resistance. Until now, little has been known about the clinical significance of the Gas6/TAM system in childhood obesity., Objectives: This study aimed to determine whether circulating Gas6 and soluble Axl (sAxl) levels are associated with adiposity, inflammation, and insulin resistance status among Taiwanese adolescents., Methods: Cross-sectional analyses using the data from the Taipei Children Heart Study-III were performed. A total of 832 adolescents (average age, 13.3 years) were included; they were divided into 3 groups: lean, overweight, and obese. Circulating Gas6 and sAxl levels, adiposity, inflammatory markers, and insulin resistance status were examined., Results: Levels of circulating Gas6 and sAxl were significantly higher in overweight and obese adolescents than in the lean group (both P < .05). Circulating Gas6 levels were significantly positively correlated with body mass index Z-score (P = .045), waist circumference (P < .001), waist to hip circumference ratio (P < .001), body fat mass (P = .02), serum high-sensitivity C-reactive protein (P = .005), and tumor necrosis factor-α levels (P = .039) among overweight and obese adolescents. The correlations remained significant after adjusting for age, gender, Tanner stage, smoking status, and drinking status. In addition, every 1 ng/mL increase in circulating Gas6 concentration corresponded to a 15% to 19% increase in the risk of developing insulin resistance among overweight and obese adolescents., Conclusions: Circulating Gas6 levels are strongly associated with adiposity, inflammation, and insulin resistance status among overweight and obese adolescents. The potential role of the Gas6/TAM system in the initiation of childhood obesity and obesity-associated complications deserves further attention.

- Abstract
Objectives: Retinol-binding protein 4 (RBP4) has a role in the development of insulin resistance (IR), type 2 diabetes, obesity, and metabolic syndrome among adults. However, data among adolescents are limited, and the effects of gender and sex hormones on RBP4 are not well defined., Materials/methods: A total of 1082 adolescents were enrolled and categorized based on their body mass index. Blood samples were collected, and biochemical characteristics, sex hormones, RBP4 concentrations, and IR were determined., Results: Testosterone and estradiol were not directly correlated with RBP4 concentrations in both genders. Multivariate regression analysis revealed that fasting plasma glucose (FPG), triglyceride (TG), and testosterone levels were independently associated with RBP4 concentrations in boys; also, there was a trend of increasing RBP4 levels with the severity of obesity., Conclusion: Plasma RBP4 concentrations correlated with obesity and cardiovascular risk factors, predominantly evident in boys. Testosterone, FPG, and TG levels were independent predictors of RBP4 concentrations.

- Abstract
Background: This study was to evaluate the relationship between the interleukin-6 receptor (IL-6R) 48892 A/C single-nucleotide polymorphism (SNP) (rs8192284) and the metabolic syndrome (MetS) and its components among young adolescents in Taiwan., Methods: We enrolled 925 adolescents (451 boys and 474 girls). Modified National Cholesterol Education Program Adult Treatment Panel-III (NCEP ATP-III) criteria were applied to define MetS (with age- and gender-specific 90th percentile cutoff point of variables). Subjects had three or more of the following cardiometabolic abnormalities that occur in MetS: high blood pressure, high fasting glucose, high triglyceride (TG), low high-density lipoprotein cholesterol (HDL-C), and obesity. The characteristics of the MetS components associated with different alleles and genotypes of the IL-6R rs8192284 SNP were compared., Results: Frequencies of alleles and genotypes of the IL-6R 48892 polymorphism were similar in both sexes. Boys with C-alleles had borderline lower TG levels than A-allele carriers (66.0±30.1 vs. 70.3±34.6 mg/dL, p=0.07). However, girls with C-alleles had higher waist circumference (WC) (68.0±7.9 vs. 67.0±7.7 cm) and lower HDL-C levels (50.7±11.1 vs. 52.2±11.7 g/dL) than A-allele carriers (p=0.05). The prevalence of MetS and its components, high WC and low HDL-C level, were higher in female C-allele carriers (all p<0.05) but not in boys. The odds ratios for high WC, low HDL-C levels, and MetS for female C-allele carriers were 1.54 (95% confidence interval [CI]: 1.01-2.34), 1.49 (95% CI: 1.01-2.18), and 2.19-2.39 (95% CI: 1.15-4.51), respectively, when compared with A-allele carriers., Conclusions: The IL-6R 48892 A/C polymorphism is associated with high TG and WC, and low HDL-C levels in adolescents. Additionally, there is a gender difference in the incidence of MetS, indicating a possible gene-gender interaction of the IL-6R 48892 A/C polymorphism in MetS among Taiwanese adolescents.

- Abstract
This study evaluates prevalence of hypertension in 1996 and 2006, and examines the relationship between hypertension and weight of Taiwanese young adolescents. Two cross-sectional surveys, administered in 1996 and 2006, to junior-high school in Taipei were included. Anthropometric and blood pressure were measured using standard methods, and structured questionnaire was used to collect personal history and lifestyle characteristics. Overweight and obesity are defined based on Taiwan's Department of Health criteria and bases pre-hypertension and hypertension on the 90th and 95th percentile distribution of blood pressure of the population of both surveys. The prevalence of pre-hypertension in Taiwan between 1996 and 2006 increased from 12.0 to 14.4% for boys and decreased from 9.5 to 9.4% for girls. Hypertension increased from 22.8-29.7% and 12.5-20.7% for both boys and girls, respectively. In 1996, compared with normal young adolescents, the risk of hypertension for overweight was 1.8 times higher for boys and 3.4 times for girls. However, the risk of hypertension for overweight in 2006 was 1.7 times higher for boys and 1.5 times higher for girls compared with normal. Every unit increment of body mass index and waist circumference was associated with 17-27% and 6-11% risk of hypertension in both genders in 1996, and was associated with 9-13% and 4% risk of hypertension among young adolescents in 2006, respectively. The prevalence of hypertension has increased significantly in young adolescents, especially for overweight. It is necessary to enrol young adolescents in weight management programs to prevent hypertension-related co-morbidities.

- Abstract
Objectives: To evaluate the association between AGEs and atherosclerotic lipid profiles among aging diabetic patients in Taiwan., Design and Methods: After age and gender matching, we selected 207 diabetic subjects and 174 diabetic subjects with proteinuria. Lipid profiles, including total cholesterol (TC), triglycerides (TG), high density cholesterol-lipoprotein (HDL-C) and low density lipoprotein-cholesterol (LDL-C) were measured using standard methods. AGEs were measured with the immunoassay method., Results: In general, males were heavier; however, females had higher AGEs, fasting glucose (GLU), TC, HDL-C and LDL-C levels than males, and had higher TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C ratios compared to males. AGEs were more strongly correlated with TG levels and TCL/LDL-C, LDL-C/HDL-C and TG/HDL-C ratios when compared to glucose or hemoglobin A1c. Subjects had higher AGEs levels (≧ 2.0 AU) with more adverse lipid profiles., Conclusion: AGEs seem to be a good biomarker to evaluate the association between diabetes and atherosclerotic disorders in aging diabetes.

- Abstract
Background: To analyze the potential genetic associations between four polymorphisms of interleukin-6 receptor (IL-6R) gene and atherosclerotic lipid profiles among young adolescents in Taiwan., Methods: Using data from the Taipei Children Heart Study-II--a cross-sectional survey in 2003. After multi-stage sampling, we selected 418 boys and 441 girls with an average age of 13.1 years. We genotyped the subjects for four IL-6R gene polymorphisms (rs4845617 G/A, rs4845623 A/G, rs8192284 A/C, and rs2229238 C/T) using a TaqMan 5' nuclease assay. Lipid profiles, including total cholesterol (CHOL), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) were measured using standard methods. We also calculated CHOL/HDL-C ratio, LDL-C/HDL-C ratio, and TG/HDL-C ratio as atherosclerotic indexes., Results: IL-6R rs8192284 A/C and rs2229238 C/T variants showed strong associations with high TG (additive model, OR = 1.58, 95%CI: 1.05-2.37; OR = 1.55, 95%CI: 1.04-2.29, respectively), low HDL-C (additive model, OR = 1.57, 95%CI: 1.03-2.39; OR = 1.68, 95%CI: 1.12-2.52, respectively), and high CHOL/HDL-C (additive model, OR = 1.68, 95%CI: 1.08-2.61, OR = 1.82, 95%CI: 1.18-2.79, respectively) in girls. We inferred five common haplotypes using rs4845617 G/A, rs4845623 A/G, and rs2229238 C/T (GAC, GAT, GGC, AAC, and AAT). In girls, the AAT haplotype was associated with a significant risk of high TG, low HDL-C, high CHOL/HDL-C, and abnormal lipid levels (high TG or low HDL-C) when compared with the GAC haplotype (OR range = 3.08-4.40, all p < 0.05)., Conclusion: The IL-6R rs8192284 A/C and rs2229238 C/T variants are associated with dyslipidemia in girls, but not in boys. The AAT haplotype of the IL-6R gene (rs4845617 G/A, rs4845623 A/G, and rs2229238 C/T) may play an important role in the pathogenesis of dyslipidemia and atherosclerosis in girls.
