Hemoglobin concentration and iron supplement during pregnancy were associated with an increased risk of gestational diabetes mellitus
妊娠期血红蛋白水平和补铁与妊娠期糖尿病风险增加有关

Glycemic control and risk factors for in-hospital mortality and vascular complications after coronary artery bypass grafting in patients with and without preexisting diabetes
血糖控制水平及其他危险因素对糖尿病与非糖尿病患者冠状动脉旁路移植术后院内死亡和血管并发症的影响

Description unavailable

Highlights

  • Smoking cessation, treating low-density lipoprotein cholesterol to target levels, preventing diabetes, and highly individualized glucose control are crucial for minimizing the risk of subsequent in-hospital death and complications after coronary artery bypass grafting (CABG).
  • Among patients with diabetes, strict glucose control significantly increased the risk of in-hospital mortality compared with moderate glucose control, whereas among nondiabetic patients with stress hyperglycemia, it reduced the risk of major complications. Thus, optimal glycemic control targets after CABG may differ among patients with and without previous diabetes.

Highlights

  • A machine learning model can significantly predict imminent development of islet autoimmunity based on environmental, genetic, and metabolic features.
  • The machine learning algorithm feature selection identified type 1 diabetes-associated single nucleotide polymorphisms from The Environmental Determinants of the Diabetes in the Young (TEDDY) analysis are correlated to related data from the Diabetes Autoimmunity Study in the Young (DAISY) study.
  • Most of the metabolic features predicting the development of islet autoantibodies belonged to three pathways; lipid oxidation, phospholipase A2 signaling, and pentose phosphate.

Associations between general and abdominal obesity and incident diabetic neuropathy in participants with type 2 diabetes mellitus
2型糖尿病患者全身性肥胖和腹部肥胖与新发糖尿病神经病变的相关性研究

Highlights

  • The present study found that abdominal obesity, defined by waist circumference, was associated with an increased risk of incident diabetic neuropathy in patients with type 2 diabetes mellitus, for both men and women.
  • These findings extend the knowledge on the sex-specific association between abdominal obesity and diabetic neuropathy among diabetic patients, which highlights the need for further studies to elucidate the mechanism underlying sex differences in the association between waist circumference and the risk of diabetic neuropathy.

Description unavailable

Highlights

  • This is the first multicenter, large-sample and cross-sectional study of the relationship between RC and urinary albumin to creatinine ratio (UACR) in the Chinese community adults.
  • RC is highly correlated with UACR, and at high RC level, the patients with critical values of blood pressure, BMI, and blood glucose has a more significant correlation between RC and UACR.

Global burden of noncommunicable diseases attributable to high fasting plasma glucose
高空腹血糖导致的全球非传染性疾病负担研究

Description unavailable

Highlights

  • The burden of noncommunicable diseases (NCDs) attributable to high fasting plasma glucose (HFPG) has increased significantly since 1990.
  • Men and the elderly have a heavier burden of NCDs caused by HFPG.
  • A higher burden of HFPG was found to be associated with a lower sociodemographic index.

Elevated circulating luteinizing hormone levels are associated with diabetic macroalbuminuria in Chinese men and postmenopausal women: A cross-sectional study
2型糖尿病男性和绝经后女性患者黄体生成素水平与晚期糖尿病肾病的关系:一项横断面研究

Description unavailable

Highlights

  • High luteinizing hormone (LH) levels are positively associated with established type 2 diabetic kidney disease (DKD) among Chinese men and postmenopausal women.
  • The positive associations between LH and macroalbuminuria risk were independent of age, diabetes duration, or other metabolic factors.
  • The increase of circulating LH may be a promising clinical factor for identifying established DKD.

Joint impact of muscle mass and waist circumference on type 2 diabetes in Japanese middle-aged adults: The Circulatory Risk in Communities Study (CIRCS)
肌肉量和腰围对日本中年人2型糖尿病的联合影响:循环系统风险的社区研究(CIRCS)

Highlights

  • This cross-sectional study of middle-aged men and women showed that low skeletal muscle mass and abdominal obesity were associated with a higher prevalence of type 2 diabetes in both sexes.
  • In addition, low skeletal muscle mass and abdominal obesity were synergistically associated with presence of type 2 diabetes in Japanese middle-aged adults.
  • In clinical practice, the assessment of skeletal muscle mass and abdominal obesity may be useful for preventing and controlling type 2 diabetes.

Detection of diabetes and prediabetes using glycosylated hemoglobin in Chinese adults living in Shanghai: A prospective analysis

Description unavailable

Highlights

  • Increasing insulin resistance in the late second trimester predicts adverse pregnancy outcomes especially for preterm delivery in women with gestational diabetes mellitus (GDM).

Sonographic and other nonglycemic factors can predict large-for-gestational-age infants in diet-managed gestational diabetes mellitus: A retrospective cohort study
超声和其他非血糖因素可以预测饮食管理中的妊娠糖尿病孕妇中的大于胎龄儿:一项回顾性队列研究

Description unavailable

Highlights

  • In diet-managed gestational diabetes mellitus pregnancies, the novel large-for-gestational-age (LGA) risk factor of fetal abdominal circumference determined at 24- to 28-week fetal ultrasound can identify women at risk as well as the known risk factors of maternal parity, prepregnancy body mass index, and gestational age.
  • Smoking reduces LGA risk but has other harms.
  • Early identification of risk factors for LGA allows early intervention to mitigate LGA risk, such as restriction of excessive further maternal gestational weight gain and other therapies, which may include insulin, though unproven.
