OBJECTIVES: The aims of this study are to (1) create clusters of joint temporal patterns of diet and physical activity (PA), and (2) determine the association of these clusters with health status indicators including body mass index (BMI), waist circumference (WC), fasting plasma glucose, hemoglobin A1c, triglyceride, high-density lipoprotein cholesterol, total cholesterol, blood pressure and health outcomes including obesity, Type 2 Diabetes (T2DM) and metabolic syndrome (MS) in U.S. adults 20–65 years. METHODS: A random day of PA from accelerometry data and the first day 24 hour dietary recall collected in the National Health and Nutrition Examination Survey 2003–2006 were used to determine absolute PA intensity, absolute energy intake, and the time of these activities. Dietary and PA data from 1,627 U.S. adults were Z-normalized. Dynamic time warping (DTW) coupled with kernel-k means clustering algorithm was used to develop joint temporal dietary and PA patterns that maximally partition individuals with similar temporal behaviors into mutually exclusive clusters derived from the data rather than predefined standards. Multivariate regression models adjusted for ptential confounders, multiple comparisons and survey design factors determined associations between joint temporal patterns and health status indicators along with health outcomes (P

This study aimed to identify unique dietary patterns, and to examine the correlation of dietary patterns with elevated blood pressure, lipid profile and fasting plasma glucose (FPG) among adults in Jiangsu Province of China.4951 individuals were selected in this cross-sectional study from nutrition and health survey in Jiangsu Province in 2014. Factor analysis was used to identify the dietary patterns. Higher quartile of the cereals-seafood-dairy dietary pattern was inversely associated with high low-density lipoprotein cholesterol (LDL) (composed to Q1, OR = 0.834, 95% CI: 0.700∼0.993, P 0.05) and FPG (composed to Q1, OR = 0.725, 95% CI: 0.609-0.862, P 0.05), while higher quartile of the traditional Jiangsu dietary pattern was positively associated with low high-density lipoprotein cholesterol (HDL) (composed to Q1, OR = 1.395, 95% CI: 1.067∼1.825, P 0.05) and high systolic blood pressure (SBP) (composed to Q1, OR = 1.238, 95% CI: 1.020∼1.503, P 0.05). Higher scores of the refined food-oriented dietary pattern was inversely related to high triglycerides (TG) (composed to Q1, OR = 0.665, 95% CI: 0.551∼0.802, P 0.05), but was positively related to high TC (composed to Q1, OR = 2.179, 95% CI: 1.817∼2.614), high LDL (composed to Q1, OR = 2.431, 95% CI: 2.037∼2.902, P 0.05) and elevated FPG (composed to Q1, OR = 1.734, 95% CI: 1.458∼2.061, P 0.05).Different structure of dietary patterns do affect the blood pressure, lipid profile and fasting plasma glucose among adults in Jiangsu Province, China.

Objective: The beta-cell stress hypothesis suggests that increased insulin demand contributes to the development of type 1 diabetes. In the TRIGR trial we set out to assess the profile of plasma glucose and HbA1c before the diagnosis of clinical diabetes compared to nondiabetic children. Research Design and Methods: A cohort of children (N = 2159) with an affected first-degree relative and increased HLA risk were recruited 2002-2007 and followed until 2017. To study the relationship between plasma glucose/HbA1c and the development of autoantibodies or clinical disease Kaplan-Meir curves were developed. Mixed models were constructed for plasma glucose and HbA1c separately. Results: A family history of type 2 diabetes was related to an increase in plasma glucose (p < 0.001). An increase in glucose from the previous sample predicted clinical diabetes (p < 0.001) but not autoantibodies. An increase of HbA1c of 20% or 30% from the previous sample predicted the development of any autoantibody (p < 0.003 resp < 0.001) and the development of diabetes (p < 0.002 resp < 0.001. Participants without autoantibodies had lower HbA1c (mean 5.18%, STD 0.24; mean 33.08 mmol/mol, STD 2.85) than those who progressed to clinical disease (5.31%, 0.42; 34.46 mmol/mol, 4.68; p < 0.001) but higher than those who developed any autoantibody (5.10%, 0.30; 32.21 mmol/mol, 3.49; p < 0.001), or multiple autoantibodies (5.11%, 0.35; 32.26 mmol/mol, 3.92; p < 0.003). Conclusions: A pronounced increase in plasma glucose and HbA1c precedes development of clinical diabetes, while the association between plasma glucose or HbA1c and development of autoantibodies is complex. Increased insulin demand may contribute to development of type 1 diabetes.

Background There existed evidence that type 2 diabetes mellitus (T2DM) prevalence and control rate have seasonal variation. Our study aimed to examine the ambient temperature and fasting plasma glucose (FPG) association and estimate temperature-adjusted T2DM prevalence and control rate. Methods Four cross-sectional health surveys with 26,350 respondents were conducted in Guangdong Province from 2007 to 2015. Multistage cluster sampling was used to recruit study participants. The data of demographic characteristics, lifestyle factors, diet and use of hypoglycemic medicine, height, weight, FPG and meteorological information were collected. And an inverse distance-weighted method was employed to estimate daily temperature exposures at the individual’ s residential district/county. Base on World Health Organization 2006 criteria, participants were divided into normal fasting glucose (NFG) participants (n = 23,877), known T2DM patients (n = 916) and newly detected T2DM patients (n = 1557). Generalized additive mixed model was employed to evaluate the nonlinear associations between temperature and FPG among different T2DM subgroups. The T2DM prevalence and control rate were estimated based on temperature-FPG association. Results The curves of temperature and FPG were downward parabola for total, NFG and known T2DM groups, while it was “U”-shaped for newly detected T2DM patients. When temperature decreased from 30 °C to 4 °C, the FPG significantly increased 0.24 (95%CI: 0.15, 0.33) mmol/L, 0.10 (95%CI: 0.06, 0.14) mmol/L and 1.34 (95%CI: 0.56, 2.12) mmol/L in total, NFG and known T2DM groups, respectively. Compared to 19 °C, newly detected T2DM patients’ FPGs were increased 0.73 (95%CI: 0.13, 1.30) mmol/L at 4 °C and 0.53 (0.00, 1.07) mmol/L at 30 °C. The model-estimated temperature-adjusted T2DM prevalence had a down and up trend, with 9.7% at 5 °C, 8.9% at 20 °C and 9.4% at 30 °C, respectively. At 5, 10, 15, 20, 25 and 30 °C, the model-estimated temperature-adjusted T2DM control rates were 33.2, 35.4, 38.2, 43.6, 49.1 and 55.2%. Conclusion Temperature was negatively associated with FPG for NFG and known T2DM subgroups, while their association was U-shape for newly detected T2DM patients. Hence, the temperature-adjusted T2DM prevalence show a dip/peak pattern and T2DM control rate display a rising trend when temperature increase. Our findings suggest temperature should be considered in T2DM clinic management and epidemiological survey.

Background: My Dose Coach (MDC) is a mobile application combined with a web portal that can suggest optimized basal insulin (BI) injection doses using Self-Measured Plasma Glucose (SMPG) and hypoglycemia data. This study aimed to evaluate its efficacy on patients reaching SMPG and Fasting blood glucose (FBG) target range 90-130 mg/dl (5-7.2 mmol/L) goals without severe hypoglycemic episodes. We also addressed the mean reduction in glycated hemoglobin (A1C), FBG, and SMPG and the improvement in the WHO’s Five Well Being Index (WBI). Methods: This prospective pilot study involved the use of MDC in outpatients with type 2 diabetes (T2DM) from a Hospital in Northern Mexico. Patients on treatment with any BI were included in the study. The follow-up was of 16 weeks. Student t-tests or McNemar test were used for effect comparisons. Results: We included 158 patients (46.8% women), mean (SD) age 51 (10.3) years. We achieved SMPG target range in 58.9% [mean (95CI) reduction of 30.9 mg/dl (22.5-37.7; P Conclusions: MDC successfully helped to achieve FBG and SMPG goals, reduced A1C, and increased WBI with no severe hypoglycemia events.

It remains unknown whether reduced air pollution levels can prevent type 2 diabetes mellitus. In this study, we investigated the associations between dynamic changes in long-term exposure to ambient fine particulate matter, defined as particulate matter with an aerodynamic diameter ≤2.5 μm (PM2.5), and changes in fasting plasma glucose (FPG) levels and incidence of type 2 diabetes. A total of 151,398 adults (ages ≥18 years) were recruited in Taiwan between 2001 and 2014. All participants were followed up for a mean duration of 5.0 years. Change in PM2.5 (ΔPM2.5) was defined as the value at a follow-up visit minus the corresponding value at the immediately preceding visit. The PM2.5 concentration in Taiwan increased during 2002–2004 and began to decrease in 2005. Compared with participants with little or no change in PM2.5 exposure, those with the largest decrease in PM2.5 had a decreased FPG level (β = −0.39, 95% confidence interval: −0.47, −0.32) and lower risk of type 2 diabetes (hazard ratio = 0.86, 95% confidence interval: 0.80, 0.93). The sensitivity analysis and analyses stratified by sex, age, body mass index, smoking, alcohol drinking, and hypertension generally yielded similar results. Improved PM2.5 air quality is associated with a better FPG level and a decreased risk of type 2 diabetes development.

Context There is a challenge to predict treatment effects in patients with type 2 diabetes mellitus (T2DM). Objective To assess and predict treatment effects in patients with T2DM through time-series analysis of continuous glucose monitoring (CGM) measurements. Method We extracted and clustered the trend components of CGM measurements to generate representative time-series profiles, which were used as a predictor of treatment effects in groups of patients. Setting and Participants We recruited 111 outpatients with T2DM at Ningbo City First Hospital, China. Intervention The patients underwent CGM measurement for 14 days at the beginning of glucose-lowering treatment. Main Outcome Measures Hemoglobin A1c (HbA1c) and fasting plasma glucose (FPG) were obtained at the beginning and after 6 months of treatment. Results 111 patients each had 960 to 1344 CGM measurements for 14 days at 96 measurements per day. The patients were classified into 3 groups according to the profiles of trend components of CGM observed values by time-series clustering method, including decreasing (47 patients), increasing (26 patients), and unchanged (38 patients) profiles. After 6 months of glucose-lowering treatment, FPG declined from 10.2 to 6.8 mmol/L (a decline of 3.4 mmol/L) in the decreasing group, from 8.9 to 9.2 mmol/L (a rise of 0.3 mmol/L) in the increasing group, and from 8.4 to 7.5 mmol/L (a decline of 0.9 mmol/L) in the unchanged group. The changes of HbA1c were 2.3%, 0.2%, and 0.9% for the 3 groups (P < 0.01), respectively. Conclusions Clustering of the trend components of CGM data generates representative CGM profiles that are predictive of 6-month therapeutic effects for T2DM.

Using a nationwide epidemiological database, we aimed to clarify the association of fasting plasma glucose (FPG) with subsequent cardiovascular disease (CVD) risk among young adults.Medical records of 1,180,062 young adults (20-49 years old) without a prior history of CVD and who were not taking antidiabetic medications were extracted from the Japan Medical Data Center. We categorized the study population into four groups: normal, FPG level100 mg/dL (1,007,747 individuals), normal-high, FPG level of 100-109 mg/dL (126,602 individuals), impaired fasting glucose (IFG), FPG level of 110-125 mg/dL (32,451 individuals), and diabetes mellitus (DM), FPG level ≥126 mg/dL (13,262 individuals). The mean age was 39.7 ± 6.9 years, and 57.0% of the study population were men. Mean follow-up period was 1201 ± 905 days on average. Multivariable Cox regression analysis showed that IFG (hazard ratio [HR]; 1.38) and DM (HR; 2.09) increased the risk of myocardial infarction. Normal-high (HR; 1.11), IFG (HR; 1.18), and DM (HR; 1.59) groups had an elevated angina pectoris risk. DM (HR; 1.31) increased the risk of stroke compared to normal FPG levels. Normal-high levels (HR; 1.10), IFG (HR; 1.22) and DM (HR; 1.58) elevated the risk of heart failure. DM (HR; 1.69) increased the risk of atrial fibrillation.Our analysis of a nationwide epidemiological database demonstrated a close association of the FPG category with subsequent CVD risk. Our results exemplify the importance of optimal FPG maintenance for the primary prevention of CVD in young adults.

Hyperglycaemia can alter placental resistance to blood flow and hyperglycaemia has adverse perinatal outcomes. Oral glucose tolerance testing (OGTT) increases the maternal plasma glucose levels temporarily and mimics metabolic hyperglycaemia. The blood flow of the uterine artery (UtA), umbilical artery (UA), middle cerebral artery (MCA) were assessed before, 1 and 2 h following the OGTT by using Doppler ultrasonography. Z-score of cerebroplacental ratio (CPR), pulsatility index (PI) for three vessels were evaluated separately. All measurements of the MCA, UA, UtA Doppler parameters were not statistically different for fasting, and 1 and 2 h following the 75 g OGTT in the 53 pregnant women with a singleton gestation in the low-risk group. This study results show that acute hyperglycaemia induced by OGTT has no effect on maternal and foetal Doppler parameters in healthy pregnancies.IMPACT STATEMENT

Regular almond consumption has been shown to improve body weight management, lipid profile and blood glucose control. We hypothesized that almond consumption would alter fecal microbiota composition, including increased abundance and activity of potentially beneficial bacterial taxa in adults who are overweight and obese with elevated fasting blood glucose. A total of 69 adults who were overweight or obese with an elevated plasma glucose (age: 60.8 ± 7.4, BMI ≥27 kg/m2, fasting plasma glucose ≥5.6 to

To explore the impact of ferritin level on the disassociation of glycated hemoglobin A1c (HbA1c) and mean plasma glucose (MPG).We used a 2012-2013 cross-sectional survey conducted in Pinggu district, Beijing including 3095 Chinese participants aged 25-75 years. We categorized their glycemic status by interviewing for diagnosed diabetes and by measuring HbA1c, fasting plasma glucose (FPG), and 2-hours post-load plasma glucose (2-hours PPG). We fitted a multivariable regression model to explore the impact of ferritin on the association of HbA1c or glycated albumin (GA) and mean plasma glucose.A total of 5.65% of participants were diagnosed as diabetes using HbA1c criteria, and 9.79% using oral glucose tolerance test criteria. Compared with males, females had significantly lower hemoglobin levels (159.82 ± 11.56 vs 135.93 ± 12.62) and lower ferritin levels (113.00 [68.55, 185.50] vs 33.40 [12.40, 70.13]). Linear regression analysis performed in different groups classified by different diagnose criterion indicated that the correlation between MPG and HbA1c differs in different tertiles of ferritin (lowest vs middle vs highest: RFerritin level might affect the association between glucose and HbA1c, which should be taken into account when using HbA1c as a diagnosis criterion for diabetes and prediabetes.目的: 探讨铁蛋白水平如何影响糖化血红蛋白(HbA1c)与平均血糖的关系 研究设计与方法: 我们使用了2012-2013年在北京市平谷区进行的横断面调查; 这项调查纳入了3095名年龄在25-75岁的中国受试者。根据了解既往确诊糖尿病史和测量HbA1c、空腹血糖与负荷后两小时血糖对受试者的血糖状况进行分类。通过拟合的多变量回顾模型; 分析铁蛋白水平如何影响平均血糖与HbA1c、糖化白蛋白的关系。 结果: 根据HbA1c标准; 共有5.65%的受试者被诊断为糖尿病; 而根据口服糖耐量试验标准则有9.79%被诊断为糖尿病。相比于男性; 女性受试者的血红蛋白水平显著更低(159.82±11.56 vs. 135.93±12.62 g/L); 铁蛋白水平也更低(113.00 [68.55, 185.50] vs. 33.40 μg/L [12.40, 70.13])。在根据不同诊断标准划分的不同组别中进行的线性回归显示; 平均血糖值和HbA1c之间的相关性在铁蛋白值三分位组中有所不同(最低、中间与最高:女性R

The purpose of this study was to investigate the influence of lunar phases on fasting plasma glucose, heart rate, and blood pressure in type 2 diabetic patients. The present cross-sectional study was carried out during four phases, i.e., full moon (FM), first quarter (FQ), new moon (NM), and third quarter (TQ), of the lunar month. The study was conducted on 42 randomly selected patients (22 males and 20 females) from the Diabetes Clinic of Calcutta Medical College. Fasting plasma glucose (FPG) of each subject was determined and heart rate (HR) and blood pressure (BP) were measured at rest and during static exercise conditions, i.e., performance of a standard handgrip dynamometer test. The FPG level during the NM and FM was significantly higher (

OBJECTIVE Acute experimental variations in glycemia decelerate (hyperglycemia) or accelerate (hypoglycemia) gastric emptying. Whether spontaneous variations in fasting plasma glucose (FPG) have a similar influence on gastric emptying is yet unclear. RESEARCH DESIGN AND METHODS Gastric emptying of a mixed meal was prospectively studied three times in 20 patients with type 1 diabetes and 10 healthy subjects with normal glucose tolerance using a 13C-CO2 octanoate breath test with Wagner-Nelson analysis. The velocity of gastric emptying was related to FPG measured before the test (grouped as low, intermediate, or high). In addition, gastric emptying data from 255 patients with type 1 diabetes studied for clinical indications were compared by tertiles of baseline FPG. RESULTS Despite marked variations in FPG (by 4.8 [95% CI 3.4; 6.2] mmol/L), gastric emptying did not differ among the three prospective examinations in patients with type 1 diabetes (Δ T1/2 between highest and lowest FPG: 1 [95% CI −35; 37] min; P = 0.90). The coefficient of variation for T1/2 determined three times was 21.0%. Similar results at much lower variations in FPG were found in healthy subjects. In the cross-sectional analysis, gastric emptying did not differ between the tertiles of FPG (Δ T1/2 between highest and lowest FPG: 7 [95% CI −10; 23] min; P = 0.66), when FPG varied by 7.2 (6.7; 7.8) mmol/L. However, higher HbA1c was significantly related to slower gastric emptying. CONCLUSIONS Day-to-day variations in FPG not induced by therapeutic measures do not influence gastric emptying significantly. These findings are in contrast with those obtained after rapidly clamping plasma glucose in the hyper- or hypoglycemic concentrations range and challenge the clinical importance of short-term glucose fluctuations for gastric emptying in patients with type 1 diabetes. Rather, chronic hyperglycemia is associated with slowed gastric emptying.

Background: Each measurement is subject to measurement uncertainty (MU). Consequently, each measurement of plasma glucose concentration used for diagnosis and monitoring of diabetes mellitus (DM) is affected. Although concepts and methods of MU are well established in many fields of science and technology, they are presently only incompletely implemented by medical laboratories, neglecting MU of target values of internal quality control (IQC) materials. Methods: An empirical and practical approach for the estimation of MU based on the analysis of routine IQC using control samples with assigned target values is presented. Its feasibility is demonstrated exemplarily by analyzing IQC data from one year obtained for glucose employing the hexokinase method with IQC of two different concentrations. Results: Combined relative extended ( k = 2) MU comprising bias, coefficient of variation (CV), and MU of the target values assigned to control materials were about 9% with a lower (~ 56 mg/dL; ~3.1 mmol/L) and 8% with a higher (~ 346 mg/dL; ~19.2 mmol/L) concentration sample, analyzing IQC of one year from three different devices. Conclusions: Estimation of MU in this study is quite reliable due to the large number of IQC data from one year. The MU of the target values of the commercial control material in this study was considerably larger than other MU contributions, ie, standard deviation and bias. In the future, the contribution of MU of commercial IQC should be addressed more carefully and technologies to measure glucose should be geared toward smaller MU possible, as needed, especially for glucose concentration measurements in diagnosis and management of DM.

Hyperglycemia is a major public health concern. An understanding of the latest trends of the global burden of noncommunicable diseases (NCDs) by high fasting plasma glucose (HFPG) is critical for determining research priorities and planning health policy.This is a comparative burden-of-disease study. We obtained global, regional, and national data on deaths and disability-adjusted life years (DALYs) of NCDs attributable to HFPG from the Global Burden of Disease Study 2017, performed a secondary analysis of deaths and DALYs by time, age, gender, location, and specific causes, and analyzed their associations.In 2017, 6.39 million deaths and 166.36 million DALYs from NCDs were attributable to HFPG, accounting for 15.6% and 10.7% of all deaths and DALYs, respectively. The burden's rate decreased with time, increased with age and was significantly higher in males. A negative association was found between the sociodemographic index (SDI) and disease burden, and a positive association was found between SDI and male superiority by gender difference and gender ratio.The burden of NCDs attributable to HFPG has increased significantly since 1990 and varied widely across regions. Greater efforts are needed to prevent and control hyperglycemia, especially in less developed countries and among males.背景: 高血糖是一个重大的公共健康问题。了解高空腹血糖导致的全球非传染性疾病负担的趋势变化对研究方向确定和卫生政策规划均有着重要作用。 方法: 这是一项关于疾病负担的对比研究, 通过从2017年全球疾病负担研究中获取全球、区域和民族的非传染性疾病死亡及伤残调整生命年(DALY)数据, 按照时间、年龄、性别、地区和特定疾病进行二次分析。 结果: 在2017年, 高空腹血糖导致的非传染性疾病共引起639万死亡和16 636万DALYs, 分别占全部死亡及DALY的15.6%和10.7%。校正年龄、人口后的疾病负担率随时间降低、随年龄增长, 且在男性中更高。此外, 疾病负担率还与社会人口指数存在显著负相关, 且该指数还与疾病负担率的男女差距呈显著正相关性。 结论: 高空腹血糖导致的非传染性疾病负担从20世纪90年代起显著增加, 且在不同地区间差异显著。对高血糖的预防和控制仍需更多努力, 尤其是在欠发达地区和男性中。.

Background/aim High levels of triglyceride (TG) and fasting blood glucose (FBG) values increase atherosclerosis risk. This study evaluates the relationship between peripheral artery disease (PAD) severity and complexity, as assessed by TransAtlantic InterSociety Consensus-II (TASC-II) classification and the triglyceride-glucose (TyG) index. Materials and methods A total of 71 consecutive patients with PAD (males 93%, mean age 63.3 ± 9.7), who underwent percutaneous peripheral intervention were included retrospectively. The patients were divided into two groups according to the angiographically detected lesions. Those with TASC A-B lesions were included in Group 1, and those with TASC C-D lesions were included in Group 2. TyG index was calculated as formula: ln[fasting TG (mg/dL) × fasting plasma glucose (mg/dL)/2]. Results There were 40 patients in Group 1 (90.3% men, with a mean age of 63.6 ± 9.3 years) and 31 patients in Group 2 (96.8% men, with a mean age of 62.0 ± 8.6 years). In the majority of patients in both groups, the target vessels are iliac arteries and femoral arteries. In Group 2, platelet count and TyG index were significantly high, according to Group 1. The TyG index was significantly correlated with TASC-II, Rutherford category, HbA1c, and HDL-C. Conclusion In this present study, we showed that the TyG index was an independent predictor of peripheral artery disease complexity, according to TASC-II classification, for the first time in the literature.

Background Allium hookeri is widely consumed as a vegetable and herbal medicine in Asia. A. hookeri has been reported anti-inflammatory, anti-obesity, osteoblastic, anti-oxidant, and anti-diabetic effects in animal studies. We investigated the anti-diabetic effects of A. hookeri aqueous extract (AHE) in the Korean subjects. Methods Prediabetic subjects (100 ≤ fasting plasma glucose (FPG)

The previous study served impaired fasting glucose (IFG), a pre-diabetic state which was much greater than that of diabetic patients, have reached no consensus on its cut-off value. In this study, we aimed to explore the cut-off value of IFG via the associations of blood lipids with fasting plasma glucose (FPG).A cross-sectional study in Jilin province, China, 2012.13,093 participants aged 18-79 years in Jilin province were involved in the study. The Lamba-Mu-Sigma (LMS) method and generalized additive model (GAM) were used to explore the associations of different levels of FPG and blood lipids.The distributions of FPG, triglyceride (TG) and high-density lipoprotein cholesterol (HDL-c) were significantly different by gender (p0.01). In general, both LMS and GAM results showed that the TG and HDL-c curves had a steeper tendency when the FPG was greater than 6.0mmol/L.FPG was positively associated with TG while negatively associated with HDL-c, and the associations were stronger in females. The cut-off value of IFG was suggested to be 6.0mmol/L.

Objective To investigate plasma glucose changes during the ictal state of migraine compared to the interictal state. Background Previous studies suggest abnormal glucose metabolism in migraine patients during and outside of attacks. It is not known if plasma glucose levels change during spontaneous migraine attacks. Methods Plasma glucose levels were measured during and outside of spontaneous migraine attacks with and without aura. Plasma glucose values were corrected for diurnal variation of plasma glucose by subtracting the difference between the moving average (intervals of 2 hours) and overall mean from the plasma glucose values. Results This was a sub-study of a larger study conducted at Rigshospitalet Glostrup in the Capital Region of Denmark. Thirty-one patients (24 F, 7 M, 13 with aura, 18 without aura) were included in the study. Mean time from attack onset to blood sampling was 7.6 hours. Mean pain at the time of investigation was 6 on a 0-10 verbal rating scale. Plasma glucose was higher ictally compared to the interictal phase (interictal mean: 88.63 mg/dL, SD 11.70 mg/dL; ictal mean: 98.83 mg/dL, SD 13.16 mg/dL, difference 10.20 mg/dL, 95% CI = [4.30; 16.10]), P = .0014). The ictal increase was highest in patients investigated early during attacks and decreased linearly with time from onset of migraine (-1.57 mg/dL/hour from onset of attack, P = .020). The attack-related increase in blood glucose was not affected by pain intensity or presence of aura symptoms. Conclusions We demonstrated higher plasma glucose values during spontaneous migraine attacks, independent of the presence of aura symptoms and not related to pain intensity, peaking in the early phase of attacks. Additional studies are necessary to confirm our findings and explore the possible underlying mechanisms.

Context: Evidence suggests thatthe 1-h post-load plasma glucose (1-h PG) ≥155 mg/dL during an oral glucose tolerance test(OGTT) predicts development oftype 2 diabetes (T2DM) and associated complications, among adults with normal glucose tolerance (NGT), but relevant data on children is scarce. Objectives: To investigate whether NGT children with obesity whose 1-h PG is ≥155 mg/dL have an increased carotid intima-media thickness (IMT) and exhibit non-alcoholic fatty liver disease (NAFLD) diagnosed by ultrasonography, as compared with NGT subjects with 1-h PG 0.05). Of the three glycemic parameters, 1-h and 2-h PG, but not fasting glucose, were significantly correlated with carotid IMT. There were no significant differences for increased risk of having NAFLD between the three groups. Conclusions: These data suggest that a value of 1-h PG ≥155 mg/dL in children and adolescents with obesity is as important as IGT with respect to cardiovascular risks.

BACKGROUND: Post-prandial and oral glucose tolerance test-related hypoglycemia is common in cystic fibrosis (CF); however, the underlying mechanisms are unclear. METHODS: To understand the relationship of hypoglycemia with meal-related glucose excursion and insulin secretion, we analyzed plasma glucose, insulin, C-peptide, glucagon and incretins obtained during standardized mixed-meal tolerance tests (MMTT) in non-diabetic adolescents and young adults with pancreatic insufficient CF (PI-CF). RESULTS: Hypoglycemia, defined as glucose

Elevated 1‐h plasma glucose (1h‐PG; ≥155 mg/dL) during an oral glucose tolerance test is a risk factor for type 2 diabetes. However, the metabolic characteristics of non‐obese Asians with elevated 1h‐PG are unknown. Thus, we studied 59 non‐obese Japanese men with normal glucose tolerance. We divided study participants into the Low 1h‐PG group (, Characteristics of non‐obese Asians with elevated 1‐h plasma glucose are unknown. Individuals with elevated 1‐h plasma glucose have lower insulinogenic index and adiponectin. Insulin sensitivity was similar between the low and high 1‐h plasma glucose groups.

Hypoglycemia is the major symptom of insulinoma. Chronic and recurrent hypoglycemia leads to the disappearance of autonomic symptoms and persistence of non-specific symptoms alone, possibly contributing to the delayed diagnosis of insulinoma and accounting for several undiagnosed cases. We previously reported the usefulness of hemoglobin A1c (HbA1c) and glycated albumin as markers for early insulinoma screening; however, their diagnostic prediction performance and diagnostic performance were not satisfactory. We hypothesized that the product of fasting plasma glucose (FPG) and HbA1c levels (FPG × HbA1c index) is low in insulinoma, and this index may be a useful marker for screening. This cross-sectional multicenter study compared 82 insulinoma patients with 100 age-, sex-, and body mass index-matched controls with normal glucose tolerance based on 75-g oral glucose tolerance test. The FPG × HbA1c index was significantly lower in the insulinoma group than in the control group. Receiver operating curve analysis showed that the optimal cutoff point of the FPG × HbA1c index to diagnose insulinoma was 447.1, and the area under the curves (AUCs) of the FPG × HbA1c index and HbA1c were 0.998 and 0.966, respectively. The AUC of the index was significantly higher than that of HbA1c (p = 0.010). Conversely, no significant difference existed between the AUC of the FPG × HbA1c index and that of the FPG/fasting immunoreactive insulin index. Thus, in apparently healthy population, the product of FPG and HbA1c yields a useful index for insulinoma screening in terms of accuracy and versatility.

The Abbott FreeStyle Libre flash glucose monitoring system (FGM) is a recently introduced, but widespread continuous glucose monitoring system. While its mean absolute relative difference (MARD) value indicating its accuracy is acceptable with reference to the self-monitoring of blood glucose (SMBG) levels, few reports have examined the MARD in sensor glucose values of FGM (FGM-SG) with reference to plasma glucose (PG) levels and the factors determining it. We performed oral glucose tolerance tests (OGTTs) in 25 Japanese subjects without diabetes. Parkes error grid analyses showed that FGM-SG with either SMBG or PG levels as a reference met International Organization for Standardization criteria. The MARD in FGM-SG with reference to SMBG levels was 10.9 ± 4.1% during OGTTs. Surprisingly, the MARD in FGM-SG with reference to PG levels was 20.3 ± 10.3% during OGTTs, revealing a discrepancy in the accuracy of FGM-SG compared with that of PG levels; moreover, the MARD showed negative correlations with fasting blood sugar level, homeostasis model assessment insulin resistance index, and body mass index (BMI). Multiple regression analyses revealed that BMI contributed the most to the MARD when FGM-SG and PG level were compared, as lean individuals have a greater MARD regardless of glucose levels. Inaccurate FGM data could potentially increase the risk of inappropriate treatment; consideration of such factors is critical to ensure reliable FGM values.

Objective: Given the association between diabetes suppression and inhibition of diet-induced elevation in glucose and insulin, we investigated the effects of adding glucomannan to rice gruel on pre- and postprandial glucose and insulin concentrations. Methods: A total of 25 Japanese subjects without a history of diabetes or gastrointestinal disease (all males; aged 37–60 years; body mass index 20.4–31.6) participated in this study. Subjects received a 75-g oral glucose tolerance test (75gOGTT) and rice gruel containing 0, 0.4, or 0.8% of glucomannan. Blood samples were then obtained at preload and at 30, 60, and 120 min after receiving 75 g of glucose or rice gruel with or without glucomannan. Results: After the 75gOGTT, 8 subjects had normal glucose tolerance (NGT), whereas 17 showed a borderline pattern. Moreover, our data showed that greater amounts of glucomannan promoted lesser 30-min postload plasma glucose and insulin levels, with differences being larger in the borderline group than in the NGT group. Conclusions: Glucomannan dose-dependently inhibited the rice gruel-induced increase in 30-min postprandial plasma glucose and insulin levels. Furthermore, greater inhibitory effects on glucose and insulin elevation were observed in the borderline group than in the NGT group.

Objective: To assess improvement in predictive performance of Global Registry of Acute Coronary Events risk score (GRS) by addition of a glucose matrix. Methods: 1,056 acute coronary syndrome (ACS) survivors without known diabetes had pre-discharge fasting (FPG) and 2-h post-load plasma glucose (2h-PG) measured. GRS was calculated. Major adverse cardiac events (MACE; death and non-fatal myocardial infarction) were recorded during follow-up. Cox proportional hazard regression predicted event-free survival. Likelihood ratio test, Akaike’s information criteria, continuous net reclassification index (NRI>0), and integrated discrimination improvement (IDI) were used to test the additional prognostic value of glycaemic indices over GRS. Results: During a median follow-up of 36.5 months, 211 MACEs (20.0%), 96 deaths (9.1%), and 115 non-fatal re-infarctions (10.9%), occurred. 2h-PG, but not FPG, independently predicted MACE-free survival at all time points (HR 1.08, 95% CI 1.03–1.13, p = 0.002, at 3 years). Risk of MACE increased by 8–11% with every 1 mmol/L rise in 2h-PG. 2h-PG significantly improved the prognostic models containing GRS. Models containing GRS and 2h-PG yielded lowest corrected Akaike’s information criteria compared to that with only GRS. 2h-PG, but not FPG, improved NRI>0 (NRI>0 0.169, p = 0.028 at 3 years) and IDI (IDI of 0.66%, p = 0.018 at 3 years) significantly at all time points during the follow-up. Conclusions: 2h-PG, but not FPG, improves performance of GRS-containing models in predicting post-ACS prognosis in the short to medium term.

The first insulin preparation injected in humans in 1922 was short-acting, extracted from animal pancreas, contaminated by impurities. Ever since the insulin extracted from animal pancreas has been continuously purified, until an unlimited synthesis of regular human insulin (RHI) became possible in the '80s using the recombinant-DNA (rDNA) technique. The rDNA technique then led to the designer insulins (analogs) in the early '90s. Rapid-acting insulin analogs were developed to accelerate the slow subcutaneous (sc) absorption of RHI, thus lowering the 2-h post-prandial plasma glucose (PP-PG) and risk for late hypoglycemia as comparing with RHI. The first rapid-acting analog was lispro (in 1996), soon followed by aspart and glulisine. Rapid-acting analogs are more convenient than RHI: they improve early PP-PG, and 24-h PG and A1C as long as basal insulin is also optimized; they lower the risk of late PP hypoglycemia and they allow a shorter time-interval between injection and meal. Today rapid-acting analogs are the gold standard prandial insulins. Recently, even faster analogs have become available (faster aspart, ultra-rapid lispro) or are being studied (Biochaperone lispro), making additional gains in lowering PP-PG. Rapid-acting analogs are recommended in all those with type 1 and type 2 diabetes who need prandial insulin replacement.

ObjectivePreviously, we found that the presence of maternal serum metals before the 24th week of gestation prospectively increased fasting plasma glucose (FPG) at 24–28 weeks. We further explored the prospective association between levels of metals and neonatal outcomes and assessed the mediating effects of FPG on these relationships.MethodsA total of 7,644 pregnant women were included in a retrospective cohort study, and the relationships between metals [manganese (Mn), copper (Cu), lead (Pb), zinc (Zn), and magnesium (Mg)] and birth outcomes were explored. Quantile and linear regressions were performed to detect the shifts and associations between metals and neonatal size distribution focused on the 10th, 50th, and 90th percentiles. Mediation analysis was performed to assess the mediating effect of FPG on metals and birth outcomes.ResultsAfter adjustment, a 50% increase in Mn and Zn levels was related to a 0.136-cm (95% CI: 0.067–0.205) and 0.120-cm (95% CI: 0.046–0.193) increase in head circumference, respectively. Based on head circumference distribution, the magnitude of the association with Mn was smaller at the upper tail, while the magnitude of correlation with Zn was greater at the upper tail. A 50% increase in Mn and Zn levels was related to a 0.135-cm (95% CI: 0.058–0.212) and 0.095-cm (95% CI: 0.013–0.178) increase in chest circumference, respectively. The magnitude of the association with Mn increased with increasing chest circumference, while the magnitude of correlation with Zn decreased with increasing chest circumference. FPG explained 10.00% and 17.65% of the associations of Mn with head and chest circumference. A positive indirect effect of Zn associated with head circumference (0.004, 95% CI: 0.002–0.006) and chest circumference (0.005, 95% CI: 0.003–0.008) through FPG was also observed, and the estimated proportion of the mediating effect was 13.79% and 26.32%, respectively.ConclusionMaternal serum Mn and Zn levels before the 24th week of gestation may prospectively increase the circumference of the neonatal head and chest. FPG at 24–28 weeks had positive mediating effects on these relationships. Further research is needed to identify a balance between maternal blood glucose and birth size.

BackgroundMild cognitive impairment (MCI) is a transitional state between normal elderly people and dementia, with a higher risk of dementia transition. The primary purpose of the current study was to investigate whether routine blood and blood biochemical markers could be used to predict the onset of MCI.MethodsData was obtained from the cohort study on brain health of the elderly in Shanghai. A total of 1015 community elders were included in the current study. Based on clinical evaluation and the scores of Montreal Cognitive Assessment (MoCA), these participants were divided into the MCI (n=444) and cognitively normal groups (n=571). Then we tested their fasting blood routine and blood biochemical indexes, and collected their general demographic data by using a standard questionnaire.ResultsBy using binary logistic regression analysis and the ROC curve, we found that elevated fasting plasma glucose (p=0.025, OR=1.118, OR=1.014-1.233) was a risk factor for MCI.ConclusionsElevated fasting blood glucose may be a risk factor for mild cognitive impairment, but the above conclusions need to be verified by longitudinal studies.

Background Diabetes have been known as a traditional risk factor of developing peripheral artery disease (PAD). However, the study evaluating the impact of long-term glycemic variability on the risk of developing PAD is limited, especially in a general population without diabetes. Methods We included 152,931 individuals without diabetes from the Korean National Health Insurance Service–Health Screening Cohort. Fasting plasma glucose (FPG) variability was measured using coefficient variance (FPG-CV), standard deviation (FPG-SD), and variability independent of the mean (FPG-VIM). Results A total of 16,863 (11.0%) incident cases of PAD were identified during a median follow-up of 8.3 years. Kaplan–Meier curves showed a progressively increasing risk of PAD in the higher quartile group of FPG variability than in the lowest quartile group (log rank P P Conclusions Increased long-term glycemic variability may have a significant prognostic effect for incident PAD in individuals without diabetes. Graphical Abstract

Objective To screen 97 obese Arab adolescents for metabolic risk factors. Results Insulin resistance, metabolic syndrome and intermediate hyperglycaemia was found in 56.7 %, 14.4 % and 27.8 % (HbA1c) while fasting plasma glucose was impaired in 0–16.5 %, using different cut-offs. Interventions to prevent obesity and diabetes are needed.

To diagnose gestational diabetes mellitus (GDM), plasma glucose measurements during oral glucose tolerance test (OGTT) put high demands on the methods in terms of accuracy. The aim was to evaluate and compare diagnostic performance of a point-of-care test and a glucose hexokinase laboratory method. Using risk-based screening, 175 pregnant women were included. They underwent a 75 g OGTT in their 28th (median) week of gestation. Venous blood was collected in two different tubes. Plasma glucose was measured on Cobas c701 and in duplicates on AccuChek Inform II (both methods from Roche Diagnostics). Accuracy was assessed by participating in external control programs with reference method assigned values. The methods were compared for all samples (

BACKGROUND: The optimal approach to screening and diagnosis of prediabetes and diabetes in youth is uncertain. METHODS: We conducted a cross-sectional analysis of 14 119 youth aged 10 to 19 years in the 1999–2016 NHANES. First, we examined the performance of American Diabetes Association risk-based screening criteria. Second, we evaluated the performance of current clinical definitions of prediabetes and diabetes based on hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), either HbA1c or FPG, or both HbA1c and FPG (confirmatory definition) to identify youth at high cardiometabolic risk. RESULTS: Overall, 25.5% of US youth (10.6 million in 2016) were eligible for screening. Sensitivity and specificity of the screening criteria for detecting any hyperglycemia were low for both HbA1c ≥5.7% (sensitivity = 55.5%, specificity = 76.3%) and FPG ≥100 mg/dL (sensitivity = 35.8%, specificity = 77.1%). Confirmed undiagnosed diabetes (HbA1c ≥6.5% and FPG ≥126 mg/dL) was rare, 85%) cases of diabetes were diagnosed. Associations with cardiometabolic risk were consistently stronger and more specific for HbA1c-defined hyperglycemia (specificity = 98.6%; sensitivity = 4.0%) than FPG-defined hyperglycemia (specificity = 90.1%; sensitivity = 19.4%). CONCLUSIONS: One-quarter of US youth are eligible for screening for diabetes and prediabetes; however, few will test positive, especially for diabetes. Most cases of diabetes in US youth are diagnosed. Regardless of screening eligibility, we found that HbA1c is a specific and useful nonfasting test to identify high-risk youth who could benefit from lifestyle interventions to prevent diabetes and cardiovascular risk in adulthood.

AIM To compare the benefits of iGlarLixi, a fixed-ratio combination of insulin glargine 100 U/mL and lixisenatide (iGlarLixi), with insulin glargine (iGlar) for reducing residual hyperglycaemia (defined as HbA1c ≥ 7% despite fasting plasma glucose [FPG]

This post hoc analysis examines the relationship between glycemic variability (GV) and fasting plasma glucose (FPG) targets used to achieve glycated hemoglobin (HbA1c) 7%, and HbA1c levels after 24 weeks of treatment with insulin glargine and oral antidiabetic drugs (OADs) in Chinese participants with type 2 diabetes mellitus (T2DM) from the BEYOND III FPG GOAL trial (NCT02545842).Participants were randomized for three FBG targets (≤ 5.6 mmol/L, ≤ 6.1 mmol/L, and ≤ 7.0 mmol/L) receiving insulin glargine 100 U/mL were analyzed for mean change from baseline to 24 weeks in postprandial glucose (PPG) excursion and FPG coefficient of variation (FPG-CV). The study analyzed change from baseline in HbA1c and the proportion of participants who achieved HbA1c 7% at 24 weeks, according to their baseline FPG-CV and change from baseline in PPG excursion.The change in PPG excursion and FPG-CV from baseline to 24 weeks was not significantly different between the three groups stratified by randomization or by 24-week FPG levels. While the change in HbA1c from baseline to 24 weeks was slightly higher among participants with baseline FPG-CV 33.3% (vs. 66.7%; P = 0.023), a higher proportion of participants with baseline FPG-CV 33.3% achieved HbA1c 7% (P = 0.021).GV was not associated with either target FPG levels or HbA1c 7.0% after 24 weeks of treatment with insulin glargine and OADs.Clinicaltrials.gov identifier NCT02545842.

Context A high prevalence of vitamin D (VD) deficiency in COVID-19 patients has been reported and hypothesized to increase COVID-19 severity likely because of its negative impact on immune and inflammatory responses. Furthermore, clear associations between hypovitaminosis D and fat body mass excess and diabetes, factors associated with COVID-19 severity, have been widely recognized. Objective The aim of this study was to evaluate in COVID-19 patients the relationship between VD levels and inflammatory response, body mass index (BMI), blood glucose (GLU), and disease severity. Methods Patients admitted to San Raffaele-Hospital for COVID-19 were enrolled in this study, excluding those with comorbidities and therapies influencing VD metabolism. 25-Hydroxyvitamin D levels, plasma GLU levels, BMI, and inflammatory parameters were evaluated at admission. Results A total of 88 patients were included. Median VD level was 16.3 ng/mL and VD deficiency was found in 68.2% of patients. VD deficiency was found more frequently in male patients and in those affected by severe COVID-19. Regression analyses showed a positive correlation between VD and PaO2/FiO2 ratio, and negative correlations between VD and plasma GLU, BMI, neutrophil/lymphocyte ratio, C-reactive protein, and interleukin 6. Patients with both hypovitaminosis D and diabetes mellitus, as well those with hypovitaminosis D and overweight, were more frequently affected by a severe disease with worse inflammatory response and respiratory parameters, compared to those without or just one of these conditions. Conclusion We showed, for the first-time, a strict association of VD levels with blood GLU and BMI in COVID-19 patients. VD deficiency might be a novel common pathophysiological mechanism involved in the detrimental effect of hyperglycemia and adiposity on disease severity.

Due to changed lifestyle and other reasons, diabetes has become one of the common metabolic disorder of the globe. Numerous therapeutic options are available, which controls the plasma glucose levels. However, most of the drugs are associated with some undesired side effects. Owing to the side effects and enhanced understanding of the phytochemicals, an inclination toward herbal medicine is seen in the population. These herbal products are also associated with concerns like poor aqueous solubility, compromised permeation, and a low degree of bioavailability. So, the emergence of nanotechnology in the herbal medicine is required to nullify the associated concerns of conventional antidiabetic drugs. The present review aims to compile the literature available for the nano-interventions pertinent to herbal products for diabetes management.

To evaluate the effects of bariatric surgery on patients with type 2 diabetes through comparing Asian and non-Asian populations according to follow-up time. In this meta-analysis of randomized controlled trials (RCTs), we searched PubMed databases for relevant articles. A meta-analysis was undertaken of 37 eligible RCTs. Diabetes remission rates among Asian populations were similar to those of non-Asian populations at 1 year (95% confidence interval (CI) 0.519 [0.417, 0.619] vs 0.571 [0.316, 0.794], respectively) but were found to be higher in Asian populations at 2 years compared to non-Asian populations (95% CI 0.672 [0.469, 0.826] vs 0.563 [0.220, 0.855], respectively). Asian populations showed greater reductions in HbA1c (− 3.512 [− 2.726, − 4.299], − 3.001 [− 1.433, − 4.569], and − 3.345 [− 2.267, − 4.423]) than non-Asian populations (− 2.129 [− 1.821, − 2.438], − 2.301 [− 1.881, − 2.722], and − 2.107 [− 1.941, − 2.273]) at 1, 2, and 5 years, respectively. Asian populations also showed greater reductions of fasting plasma glucose than non-Asian populations, and these effects were prominent at 3- and 5-year follow-up (Asian populations, − 83.297 [− 73.264, − 93.331]; non-Asian populations, − 54.288 [− 37.409, − 71.166] at 3 years; Asian populations, − 99.014 [− 82.239, − 115.788]; non-Asian populations, − 45.756 [− 21.892, − 69.621] at 5 years). Bariatric surgery is more successful in diabetes remission and glucose outcome improvement in Asian populations with type 2 diabetes than in non-Asian populations, even over long-term follow-up periods. Bariatric surgery can be considered an effective treatment option and may present an appropriate opportunity to improve the prognosis for Asian patients with type 2 diabetes.

Aims To assess the efficacy, insulin dose, safety and immunogenicity when people with type 1 diabetes mellitus switched between MYL‐1501D and reference insulin glargine (Lantus®; Sanofi‐Aventis US LLC, Bridgewater, New Jersey). Materials and methods Eligible participants from INSTRIDE 1 who completed 52 weeks of reference insulin glargine treatment were randomized 1:1 to the reference sequence (n = 63; reference insulin glargine for 36 weeks) or to the treatment‐switching sequence (n = 64; MYL‐1501D [weeks 0–12], reference insulin glargine [weeks 12–24] and MYL‐1501D [weeks 24–36]). Change in glycated haemoglobin (HbA1c) from baseline to week 36 was the primary efficacy endpoint used to demonstrate equivalence between the two treatment sequences. Secondary endpoints included: change in fasting plasma glucose (FPG), self‐monitored blood glucose (SMBG) and insulin dose; immunogenicity; and adverse events, including hypoglycaemia. Results Mean changes in HbA1c (least squares [LS] mean [SE]) from baseline to week 36 were −0.05 (0.032) and −0.06 (0.034) for the treatment‐switching and reference sequences, respectively (LS mean difference 0.01 [95% CI −0.085 to 0.101]). Treatment sequences were comparable in terms of secondary endpoints, including FPG, SMBG and insulin dose, and the safety and immunogenicity profiles of the two sequences were similar. Conclusions Switching participants between MYL‐1501D and reference insulin glargine demonstrated equivalent efficacy and similar safety and immunogenicity, showing that people taking reference insulin glargine can safely switch to MYL‐1501D.

OBJECTIVES: To investigate the association between habitual midday napping and impaired fasting glucose (IFG), and the interactive effect of napping and time in bed (TIB) at night on IFG among healthy adolescents. METHODS: The sample was comprised of 625 early adolescents (12.26 ± 0.63 years old) who self-report good health status from Jintan, China. Midday napping and nighttime sleep were measured using the Youth Self-report Sleep Questionnaire. Fasting plasma glucose was dichotomized into normal (

BackgroundStatistical data on the incidence, mortality, and burden of breast cancer and the relevant risk factors are valuable for policy-making. We aimed to estimate breast cancer incidence, deaths, and disability-adjusted life years (DALYs) by country, gender, age group, and social-demographic status between 1990 and 2017.MethodsWe extracted breast cancer data from the 2017 Global Burden of Disease (GBD) study from 1990 through 2017 in 195 countries and territories. Data about the number of breast cancer incident cases, deaths, DALYs, and the age-standardized rates were collected. We also estimated the risk factors attributable to breast cancer deaths and DALYs using the comparative risk assessment framework of the GBD study.ResultsIn 2017, the global incidence of breast cancer increased to 1,960,681 cases. The high social-development index (SDI) quintile included the highest number of breast cancer death cases. Between 2007 and 2017, the ASDR of breast cancer declined globally, especially in high SDI and high middle SDI countries. The related DALYs were 17,708,600 in 2017 with high middle SDI quintile as the highest contributor. Of the deaths and DALYs, alcohol use was the greatest contributor in most GBD regions and other contributors included high body mass index (BMI) and high fasting plasma glucose.ConclusionThe increasing global breast cancer burden is mainly observed in lower SDI countries; in higher SDI countries, the breast cancer burden tends to be relieving. Therefore, steps against attributable risk factors should be taken to reduce breast cancer burden in lower SDI countries.

Aim This study investigated the clinical characteristics of diabetic ketoacidosis (DKA) and compared the DKA characteristics between patients treated with and without SGLT2 inhibitors. Methods Data were collected from patients aged ≥ 18 years admitted for DKA at nine centres in Korea between September 2014 and April 2017. The electronic medical records of these subjects were retrospectively reviewed. Based on their history of medications taken before admission, subjects were classified as either users or non-users of SGLT2 inhibitors and their clinical characteristics of DKA were compared. Results During the study, the main subtype of DKA episodes (n = 523) was identified as type 2 diabetes (51%). Average hospitalization duration was 11 days, and average intensive care unit (ICU) time was 2.5 days. The in-hospital mortality rate was 3%, but no users of SGLT2 inhibitors died during DKA treatment. In patients taking SGLT2 inhibitors (n = 15), DKA manifested at 124 days, on average, after starting the inhibitors (range: 7–380 days). Also, SGLT2 inhibitors users had significantly lower plasma glucose levels (413 mg/dL) compared with non-users (554 mg/dL), and longer ICU stays (4 vs. 2 days; P = 0.019). Conclusion In this report of recent data on the clinical features of DKA in Korea, patients using SGLT2 inhibitors needed longer treatment in ICUs compared with non-users and had lower levels of blood glucose, whereas DKA associated with SGLT2 inhibitors was rare.

Objective: We aimed to predict subsequent gestational diabetes mellitus (GDM) by fasting plasma glucose (FPG) in the first trimester. Methods: Healthy pregnant women who were screened for GDM at 24-28 gestational weeks and had FPG levels calculated during their first antenatal visit and less than 14 gestational weeks were included in this study. Results: Of the 2605 women who were recruited for the study, 245 (9.4%) were diagnosed with GDM at weeks 24-28. The diagnostic accuracy for FPG predicting GDM was 66.5, 78.4, and 88.2 for the cutoff values of 87.5 mg/dl, 92 mg/dl, and 99.5 mg/dl, respectively. Conclusions: FPG values which are within the normoglycaemic range constitute an independent risk factor for the development of GDM. The threshold for gestational diabetes diagnosis must be revised.

Zinc oxide nanoparticles (ZnO NPs) represent an important class of commercially applied materials. Recently, adverse effects of ZnO NPs were found in humans and animals following ingestion, although the effects on endocrine system disease remain unclear. In this study, ZnO NPs were orally administered to mice, and at doses of 25 mg/kg bw (body weight) ZnO NPs and above, plasma glucose increased significantly. The genome-wide effects of ZnO NPs were then investigated using RNA-sequencing technology. In the cluster analysis, the most significantly enriched Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways concerned membranes and their close association with endoplasmic reticulum (ER) stress and reactive oxygen species (ROS) generation. Biochemical and gene and protein expression analyses revealed that ZnO NPs activated a xenobiotic biodegradation response and increased the expression of cytochrome P450 (CYP) enzymes in mice livers, leading to ER stress. The ER stress increased ROS generation. The high levels of ROS activated the MAPK and NF-κB pathways and induced an inflammation response, resulting in the phosphorylation of insulin receptor substrate 1. Thus, the insulin resistance that developed was the primary mechanism for the increase in the plasma glucose of mice treated orally with ZnO NPs.

Aims To compare conversion rates of diabetes in subjects with elevated 1 h plasma glucose (1hrPG) during an OGTT with normal glucose tolerance(NGT) subjects over a period of 11 years. Methods 4023 subjects were selected from electronic data base of medical records.233 subjects who were followed up for a period of 11 years were included.160 with isolated prediabetes and their combinations were excluded.The remaining 73 were categorized into group1 NGT (n = 37) and group-2 (n = 36) with elevated 1hrPG.Kaplan Meier curves for incident diabetes and Cox proportional hazard model were compared between groups. Results During follow up, 10.8% and 44.4% converted to DM in group1 and group2 (p = 0.003). Elevated 1hrPG was associated with incident diabetes(HR 7.9[95%CI 2.2–28.1](p = 0.001)provided better risk assessment.The adjusted risk of event in subjects with elevated 1hrPG is likely to be 7 times more when compared to NGT.Subjects with elevated1hrPG remained free of diabetes for a median period of 7.6 years (95% CI 5.8–7.8) whereas NGT subjects remained free for 10 years (95% CI 8.5–10.0) (p Conclusion In conclusion, conversion to DM was higher and risk was 7 times more in subjects with elevated 1hrPG. Elevated 1hrPG during OGTT has to be considered as a distinct entity.

Aims/Introduction Exercise training is a recognized strategy central to the prevention, treatment, and management of diabetes and prediabetes. The aim of the present study was to investigate the association between physical activity and blood glucose, as well as the influence of sex, menopause status and family history of diabetes. Materials and Methods Participants with normal weight were selected from Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal Study, and divided into inactive (moderate‐to‐vigorous‐intensity physical activity [MVPA] 420 min/week) activity groups. Results A total of 2,601 individuals with an average age of 57.85 ± 8.39 years were enrolled. Multivariate anova uncovered that after adjustment for sex and menopause status, and family history of diabetes, respectively, fasting plasma glucose, 2‐h plasma glucose and glycated hemoglobin A1c decreased through inactive, low‐degree and high‐degree activity groups (all P for trend
