Malnutrition in early life increases the risk of osteoporosis,but the association of early-life undernutrition combined with adulthood obesity patterns with low-energy fracture remains unknown.This study included 5323 community-dwelling subjects aged⩾40 years from China.Early-life famine exposure was identified based on the participants’birth dates.General obesity was assessed using the body mass index(BMI),and abdominal obesity was evaluated with the waist-to-hip ratio(WHR).Low-energy fracture was defined as fracture occurring after the age of⩾40 typically caused by falls from standing height or lower.Compared to the nonexposed group,the group with fetal,childhood,and adolescence famine exposure was associated with an increased risk of fracture in women with odds ratios(ORs)and 95%confidence intervals(CIs)of 3.55(1.57–8.05),3.90(1.57–9.71),and 3.53(1.05–11.88),respectively,but not in men.Significant interactions were observed between fetal famine exposure and general obesity with fracture among women(P for interaction=0.0008).Furthermore,compared with the groups with normal BMI and WHR,the group of women who underwent fetal famine exposure and had both general and abdominal obesity had the highest risk of fracture(OR,95%CI:3.32,1.17–9.40).These results indicate that early-life famine exposure interacts with adulthood general obesity and significantly increases the risk of low-energy fracture later in life in women.

G protein-coupled receptors(GPCRs)are a large family of membrane protein receptors,and Takeda G protein-coupled receptor 5(TGR5)is a member of this family.As a membrane receptor,TGR5 is widely distributed in different parts of the human body and plays a vital role in regulating metabolism,including the processes of energy consumption,weight loss and blood glucose homeostasis.Recent studies have shown that TGR5 plays an important role in glucose and lipid metabolism disorders such as fatty liver,obesity and diabetes.With the global obesity situation becoming more and more serious,a comprehensive explanation of the mechanism of TGR5 and filling the gaps in knowledge concerning clinical ligand drugs are urgently needed.In this review,we mainly explain the anti-obesity mechanism of TGR5 to promote the further study of this target,and show the electron microscope structure of TGR5 and review recent studies on TGR5 ligands to illustrate the specific binding between TGR5 receptor binding sites and ligands,which can effectively provide new ideas for ligand research and promote drug research.

Background: Whether the dynamic weight change is an independent risk factor for mortality remains controversial. This study aimed to examine the association between weight change and risk of all-cause and cause-specific mortality based on the Linxian Nutrition Intervention Trial (NIT) cohort.Methods: Body weight of 21,028 healthy residents of Linxian, Henan province, aged 40-69 years was measured two times from 1986 to 1991. Outcome events were prospectively collected up to 2016. Weight maintenance group (weight change <2 kg) or stable normal weight group was treated as the reference. Cox proportional hazard model was performed to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs) to estimate the risk of mortality.Results: A total of 21,028 subjects were included in the final analysis. Compared with the weight maintenance group, subjects with weight loss ≥2 kg had an increased risk of death from all-cause (HRAll-cause = 1.14, 95% CI: 1.09-1.19,P <0.001), cancer (HRCancer = 1.12, 95% CI: 1.03-1.21,P = 0.009), and heart disease (HRHeart diseases = 1.21, 95% CI: 1.11-1.31,P <0.001), whereas subjects with weight gain ≥5 kg had 11% (HRCancer = 0.89, 95% CI: 0.79-0.99,P = 0.033) lower risk of cancer mortality and 23% higher risk of stroke mortality (HRStroke = 1.23,95% CI: 1.12-1.34,P <0.001). For the change of weight status, both going from overweight to normal weight and becoming underweight within 5 years could increase the risk of total death (HROverweight to normal = 1.18, 95% CI: 1.09-1.27; HRBecoming underweight = 1.35, 95% CI: 1.25-1.46) and cancer death (HROverweight to normal = 1.20, 95% CI: 1.04-1.39; HRBecoming underweight = 1.44, 95% CI: 1.24-1.67), while stable overweight could increase the risk of total death (HRStable overweight = 1.11, 95% CI: 1.05-1.17) and death from stroke (HRStable overweight = 1.44, 95% CI: 1.33-1.56). Interaction effects were observed between age and weight change on cancer mortality, as well as between baseline BMI and weight change on all-cause, heart disease,

To the Editor:Type 1 diabetes mellitus(T1DM)is a progressive disease caused by severe islet b-cell function impairment,resulting in high glucose variability(GV)in patients.[1]While intensive insulin treatment enabled T1DM patients to achieve near-normal glucose,reflected by reduced hemoglobin A1c(HbA1c)levels,stricter HbA1c targets were associated with an increased risk of hypoglycemia,which would compromise patients’quality of life and survival.[2]Recent studies suggest that GV reflects hypoglycemia better than HbA1c alone,and continuous glucose monitoring(CGM)provides a more comprehensive glycemic profile for better glucose indices assessment.[3]Therefore,we aimed to explore the relationship between the coefficient of variability(CV)of blood glucose and hypoglycemia in T1DM patients with different HbA1c levels and to identify the optimal cut-off values of CV for reducing the hypoglycemia risk in Chinese T1DM patients.

To the Editor:Glycemic control in individuals with type 1 diabetes(T1D)is challenging and requires multidimensional evaluation and precise management.Glycated hemoglobin(HbA1c)is currently the gold standard for assessing glucose control and predicting diabetes prognosis.However,it exhibits limitations in terms of accuracy,which is influenced by clinical factors,^([1])and its inability to reflect information about hypoglycemia and glycemic variability.[2]Continuous glucose monitoring(CGM)has revolutionized glycemic profile evaluation by introducing novel glycemic variables that surpass conventional parameters and offer insights into critical areas for improving glycemic control.
