Women with a history of gestational diabetes (GD) are at high risk for developing type 2 (T2D). Sleep is crucial lifestyle factor associated cardiometabolic health, yet studies on its role in the progression from GD to T2D sparse. To investigate associations sleep duration and quality levels glucose metabolism biomarkers women GD. This cohort study used data Nurses' Health Study II, an ongoing longitudinal that began 1989 initially included 116 429 female nurses health status factors updated...

With the rapid development of sports technology, smart wearable devices play a crucial role in athletic training and health management. Sports fatigue is key factor affecting performance. Using to detect onset can optimize training, prevent excessive resultant injury, increase efficiency safety. However, current sensing are often uncomfortable imprecise. Furthermore, stable methods for detection not yet established. To address these challenges, this paper introduces 3D printing deep learning...

Abstract Healthy maternal diets during pregnancy are an important protective factor for pregnancy‐related outcomes, including gestational weight gain (GWG) and birth outcomes. We prospectively examined the associations of dietary diversity diet quality, using Minimum Dietary Diversity Women (MDD‐W) Prime Diet Quality Score (PDQS), with GWG outcomes among women enrolled in a trial Tanzania ( n = 1190). MDD‐W PDQS were derived from baseline food frequency questionnaire. monthly followed until...

Abstract Healthy dietary patterns, such as the alternate Mediterranean diet and Eating Index, benefit cardiometabolic health. However, several food components of these patterns are primary sources environmental chemicals. Here, using data from a racially ethnically diverse US cohort, we show that healthy pattern scores were positively associated with plasma chemical exposure in pregnancy, particularly for Index polychlorinated biphenyls per- poly-fluoroalkyl substances. The associations...

In this report, we introduce Qwen2.5, a comprehensive series of large language models (LLMs) designed to meet diverse needs. Compared previous iterations, Qwen 2.5 has been significantly improved during both the pre-training and post-training stages. terms pre-training, have scaled high-quality datasets from 7 trillion tokens 18 tokens. This provides strong foundation for common sense, expert knowledge, reasoning capabilities. post-training, implement intricate supervised finetuning with...

Abstract Background Appropriate gestational weight gain (GWG) is important for optimal pregnancy outcomes. This study prospectively evaluated the associations between GWG during second and third trimesters of adverse outcomes in an urban Tanzanian cohort. Methods We used data from a randomized clinical trial conducted among pregnant women recruited by 27 weeks gestation Dar es Salaam, Tanzania (N = 1230). Women’s was measured at baseline monthly antenatal visits. Weekly rate calculated...

Abstract Background Early pregnancy weights are needed to quantify gestational weight gain accurately. Different methods have been used in previous studies impute early-pregnancy weights. However, no systematically compared imputed accuracy across different imputation techniques. This study aimed compare four methodological approaches imputing weight, using repeated measures of collected from two cohorts Tanzania. Methods The mean ages at enrollment were 17.8 weeks for Study I and 10.0 II....

Background: The Cognitive role of untreated type 2 diabetes mellitus (T2DM) has been less well substantiated. Objective: We sought to explore the prospective association T2DM and with cognitive function among middle-aged older Chinese adults. Methods: Data 7,230 participants without baseline brain damage/mental retardation, or memory-related diseases in China Health Retirement Longitudinal Study (CHARLS) from 2011– 2012 2015, were analyzed.

Abstract Background Increasing maternal glycaemia across the continuum during pregnancy may predispose offspring to subsequent cardiometabolic risk later in life. However, evidence of long-term impacts glycemic status on amino acid (AA) profiles is scarce. We aimed investigate association between antenatal and mid-childhood profiles, which are emerging biomarkers. Methods Data were drawn from Growing Up Singapore Towards healthy Outcomes (GUSTO) study, a multi-ethnic Asian birth cohort. A...
