The present study confirms that a history of diabetes mellitus and high AGL are associated with unfavorable functional outcomes at 3 months after MT in AIS patients. However, the causal relationship between hyperglycemia and poor prognosis remains undetermined, and further investigations are required to ascertain whether AIS patients receiving MT could benefit from intensive glucose control.

ObjectivesWe performed a meta-analysis of all of the available randomised controlled trials (RCTs) to investigate whether physical exercise contributes to weight loss or physical function improvement in adults receiving bariatric surgery.MethodsWe searched PubMed, Embase, the Cochrane Library, OVID and the CINAHL up through May 2018. RCTs that assigned adults with obesity to either an exercise training group or a no-exercise group after bariatric surgery were included. The primary outcomes were weight loss and physical function. Study bias was assessed using the Cochrane risk of bias tool, and the quality of evidence was assessed using GRADEpro.ResultsA total of eight studies met the inclusion criteria (n=347 participants). Most of the studies carried a low risk of bias due to randomisation and blinding. Compared with those without exercise intervention after surgery, patients engaging in physical exercise were associated with greater weight loss (weighted mean difference (WMD) −1.94 kg; 95% CI −3.18 to −0.69; n=8) and longer 6 min walk distance (6MWD; WMD29.67 m; 95% CI 25.97 to 33.37; n=2) during follow-up. By subgroup analyses, the additional weight loss in exercise group was related to the starting time and type of exercise: patients engaging in exercise 1 year or more after surgery and patients received aerobic–resistance exercise experienced more weight loss. Besides, patients in exercise training group also had lower systolic blood pressure and resting heart rate after surgery. The quality of evidence for these outcomes was moderate to very low.ConclusionsPhysical exercise after bariatric surgery provides 1.94 kg additional weight loss and 29.67 m longer 6MWD compared with surgery alone. Moreover, engaging in exercise 1 year or more after surgery, and a combined aerobic and resistance training programme may result in greater weight loss.

Background Pre-pregnancy overweight and obesity are negatively associated with delayed onset of lactogenesis II (OL), but the mechanisms by which these conditions affect OL are still unclear. Objectives To identify biological factors related to pre-pregnancy overweight/obesity and determine whether these biological factors were associated with delayed OL in this population. Methods In this prospective observational study, we assigned 72 primipara to a pre-pregnancy overweight/obese group ( n = 36) and a normal-weight group ( n = 36). Blood samples were collected at 37 w of gestation and 48 h postpartum and assayed for levels of the following hormones: leptin, insulin, estradiol, prolactin (PRL), progesterone, and oxytocin. The primary outcome was timing of OL, estimated by maternal perception of breast fullness. We used linear-regression analysis to determine associations between hormones and delayed OL. Results Sixty-three participants (87.5%) had complete data. OL occurred later in overweight/obese than in normal-weight women ( p < .001). Compared with the normal-weight group, the overweight/obese group showed higher leptin levels at both times of observation and exhibited a slower drop in estrogen concentrations from 37 w of gestation to 48 h postpartum (all p < .05). After adjusting for confounding factors, leptin concentrations in late pregnancy and the magnitudes of decline in estrogen concentrations at 48 h postpartum were correlated with OL. Conclusion Women who were overweight/obese before pregnancy had elevated leptin levels in late pregnancy and a delayed decline in estrogen concentrations at 48 h postpartum. Both of these phenomena were related to delayed OL in this population.
