Objective: To investigate differences in body composition and fat distribution between women with previous pre-eclampsia or small-for-gestational-age (SGA) offspring and those with uncomplicated pregnancies.
Design: Cohort study.
Setting: Population-based study in a genetically isolated population in the southwest of the Netherlands.
Population: Women after pregnancies complicated by pre-eclampsia (n=45), SGA offspring (n=53) and uncomplicated pregnancies (n=106).
Methods: Women were compared for body composition and fat distribution variables, assessed by dual-energy X-ray absorptiometry (DXA) and anthropometrics at a mean follow-up time of 10.8 (SD +/- 5.9) years after pregnancy.
Main Outcome Measures: Total lean and fat mass, android fat mass, gynoid fat mass, android-to-gynoid fat ratio, waist and hip circumference, waist-to-hip ratio.
Results: Women with previous pre-eclampsia compared with controls had higher mean total fat mass index (11.5 +/- 0.6 versus 9.7 +/- 0.4 kg/m(2); P = 0.03), lean mass index (15.8 +/- 0.3 versus 14.5 +/- 0.2 kg/m(2); P =0.001) and body mass index ([BMI]; 28.4 +/- 0.8 versus 25.4 +/- 0.5 kg/m(2); P = 0.005). Their waist circumferences (90.7 +/- 2.0 versus 78.5 +/- 1.3 cm; P < 0.001) and waist-to-hip ratios (0.86 +/- 0.01 versus 0.77 +/- 0.01; P < 0.001) were also higher as well as android fat mass (2.8 +/- 0.2 versus 2.1 +/- 0.1 kg; P = 0.01) and android-to-gynoid fat ratios (0.45 +/- 0.02 versus 0.39 +/- 0.01; P = 0.02). Mean total fat, lean and BMI was not significantly different between women with previous SGA offspring and controls, yet waist-to-hip ratios (0.83 +/- 0.01; P < 0.001) were higher. The observed differences in waist and hip circumference, waist-to-hip ratio and gynoid fat mass could not be attributed to differences in BMI.
Conclusion: Women with previous pre-eclampsia or SGA offspring pregnancies compared with those with uncomplicated pregnancies have a preferential fat accumulation in the abdominal over hip region, which may explain, at least partly, their increased cardiovascular risk.

Unlabelled: This study compared denosumab and zoledronic acid for treating osteoporosis in drug-naïve postmenopausal Korean women. Over 3 years, both drugs significantly increased bone mineral density. However, denosumab also improved fat-free mass, suggesting it may be a better initial treatment for osteoporosis with low muscle mass, assuming all other conditions remain constant.

Colorectal cancer (CRC) is highly resistant to ferroptosis, which hinders the application of anti-ferroptosis therapy. Through drug screening, it is found that histone deacetylase inhibitor (HDACi) significantly sensitized CRC to ferroptosis. The combination of HDACi and ferroptosis inducers synergically suppresses CRC growth both in vivo and in vitro.

Global health is increasingly challenged by the growing prevalence of obesity and its associated complications. Quercetin, one of the most important dietary flavonoids, is being explored as an effective therapy for obesity with its mechanism remains understudied. Here in this study, it is demonstrated that quercetin intervention significantly reverses obesity-related phenotypes through reshaping the overall structure of microbiota, especially boosting colonization of the beneficial gut commensal Akkermansia muciniphila (A.

The food system significantly affects the environment through land use, emissions from livestock, deforestation, and food waste. Diet sustainability considers the environmental effects of food production, distribution, and consumption. Animal products emit more greenhouse gases than plant-based foods, prompting a shift towards plant-focused diets for reduced emissions.

Background: Muscle diseases are serious challenges to human health. Prokineticin receptor 1 (PROKR1) has emerged as a potential target to improve muscle function through increasing oxidative muscle fibres, but there are no clinically applicable synthetic PROKR1 agonists.
Methods: Drugs with biological properties of prokineticin 2 (PK2) were discovered through connectivity map (CMap) analysis.
