Article Synopsis
  • The study investigates how maternal serum iodine concentrations (SIC) relate to thyroid function and various birth outcomes among pregnant women aged 18-45 in the Huizhou Mother-Infant Cohort.
  • It includes a significant sample size of 1558 mothers, analyzing SIC and thyroid health using advanced testing methods, and features case-control studies comparing mothers with gestational diabetes and newborns with small for gestational age to healthy controls.
  • Results show that high SIC in the first trimester is linked to a higher risk of small for gestational age babies and negatively affects gestational weight gain and birth size, while also indicating strong diagnostic potential for thyroid dysfunction.*

The potential threshold for dietary energy intake (DEI) that might prevent protein-energy wasting (PEW) in chronic kidney disease (CKD) is uncertain. The subjects were non-dialysis CKD patients aged ≥ 14 years who were hospitalised from September 2019 to July 2022. PEW was measured by subjective global assessment.

Malnutrition significantly hampers wound healing processes. This study aimed to compare the effectiveness of the Global Leadership Initiative on Malnutrition (GLIM) and Subjective Global Assessment (SGA) in diagnosing malnutrition and predicting wound healing in patients with diabetic foot ulcers (DFU). GLIM criteria were evaluated for sensitivity (SE), specificity (SP), positive predictive value, negative predictive value and kappa (κ) against SGA as the reference.

The study aims to establish trimester-specific reference ranges for serum iodine (SI) in Chinese pregnant women and explore its associations with maternal and infantile thyroid function. Apparently healthy pregnant women were enrolled during their first antenatal visit. Fasting venous and spot urine samples were collected for determining serum and urinary iodine (UI) levels by a validated inductively coupled plasma mass spectrometry.

Objective: Chronic kidney disease (CKD) has become a major global health issue, and abnormalities of glucose metabolism are a risk factor responsible for development of CKD. We aimed to investigate associations between glucose metabolism indices and CKD in a Chinese population and determine which index is superior for predicting incident CKD.

Methods: We performed a community-based population on 5232 subjects aged ≥40 years without baseline CKD.

Article Synopsis
  • The study examined the relationship between maternal serum iodine concentration (SIC) and pregnancy outcomes in Chinese women, focusing on singletons aged 20-34.
  • Significant findings included that higher SIC levels during early and mid-pregnancy were linked to reduced gestational weight gain (GWG) and improved Apgar scores at birth.
  • The research also identified a U-shaped relationship where high SIC levels could lead to increased risks of small for gestational age (SGA) and premature rupture of membranes (PROM).

A tool was constructed to assess need of an oral glucose tolerance test (OGTT) in patients whose fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are normal. Data was collected from the longitudinal REACTION study conducted from June to November 2011 (14,686 subjects, aged ≥ 40 y). In people without a prior history of diabetes, isolated high 2-hour plasma glucose was defined as 2-hour plasma glucose ≥ 11.

Article Synopsis
  • Developed a risk prediction model for gestational diabetes mellitus (GDM) in Chinese women using maternal demographics and clinical factors, finding a 17.2% prevalence rate among the studied population.
  • The model utilized multivariable logistic regression and demonstrated good consistency and predictive ability through various statistical tests, including ROC curve analysis and cross-validation.
  • A user-friendly nomogram was created for clinical practice, providing an effective tool for predicting GDM risk based on common maternal characteristics.

We aimed to investigate the relationship between the neutrophil to lymphocyte ratio (NLR) and nutritional parameters in chronic kidney disease (CKD) patients. In this cross-sectional study, 187 non-dialysis CKD patients were enrolled. Daily dietary energy intake (DEI) and daily dietary protein intake (DPI) were assessed by 3-d dietary records.

Objective: Adiponectin is an adipocyte-derived hormone with an important role in glucose metabolism. The present study explored the effect of adiponectin in diverse population groups on pre-diabetes and newly diagnosed diabetes.

Methods: A total of 3300 individuals were enrolled and their data were collected in the analyses dataset from December 2018 to October 2019.

Background: This study aimed to explore the association between uric acid lowering and renal function.

Materials And Methods: We conducted a population-based cohort study with 1,534 subjects for 4 years from 2012 to 2016. The population was divided into four groups according to the interquartile range of changes in serum uric acid with quartile 1 representing lower quarter.

Background: Due to the lack of evidence, advice pertaining to glycemic load (GL) can be misleading. Does the excessive restriction of GL, mostly through an extreme reduction in carbohydrate intake, result in a relatively high intake of fat and protein and result in overweight and obesity? This study was performed to initially explore the optimal GL range.

Methods: A cross-sectional study involving 2029 participants aged 40 years or older in Guangzhou, China was conducted.

Purpose: We elucidate the effect of Growth differentiation factor-15(GDF-15)/adiponectin ratio in improving the assessment value for odds of type 2 diabetes.

Methods: Cross-sectional design. A total of 405 participants (135 patients with newly diagnosed type 2 diabetes, 135 age- and sex-matched participants with prediabetes, and 135 healthy controls) were collected from Guangzhou and Dongguan, China.

We aimed at exploring the value of neutrophil and neutrophil-to-lymphocyte ratio (NLR) as predictive risk markers for recurrent pregnancy loss (RPL) by conducting a retrospective case-control study and a systematic review and meta-analysis. This retrospective case-control study was conducted in an academic hospital from January 2012 to June 2018 and 133 cases of women with RPL and 140 control women. In parallel, we conducted a systematic review and meta-analysis on the value of NLR and neutrophil in RPL risk assessment.

Objectives: Plant oil for cooking typically provides 40% to 50% of dietary fat, 65% of linoleic acid, 44% of α-linolenic acid and 41% of oleic acid in the Chinese diet. However, the comparative effects of fatty acids derived from plant oil on cardiovascular risk factors in Chinese are still inconclusive. Hence, the aim of this study is to investigate whether cardiovascular risk factors are altered depending on various types of plant oils such as peanut oil rich in oleic acid, corn oil rich in linoleic acid, and blend oil fortified by α-linolenic acid.

Few prospective studies evaluating the association between dietary glycemic load (GL) and diabetes have accounted for changes in GL. However, the diet of patients could be modified in response to an awareness of pre-diabetes. The aim of this study was to examine the longitudinal associations between changes in GL and the incidence of diabetes among pre-diabetic patients.
