Gastric emptying in pregnancy and its clinical implications: a narrative review.

Delayed gastric emptying increases the risk of pulmonary aspiration during anaesthesia for Caesarean delivery. Our aim in conducting this narrative review was to consider the effect of pregnancy on gastric emptying. The indices of gastric emptying after liquids, solids, or both and when fasted in the various trimesters of pregnancy, at the time of Caesarean delivery, in labour, and the postpartum period were assessed.

Regeneration and growth in crowns and rhizome fragments of Japanese knotweed () and desiccation as a potential control strategy.

(Japanese knotweed) is a problematic invasive plant found in many areas of Europe and North America. Notably, in the UK, the species can cause issues with mortgage acquisition. Control of is complicated by its ability to regenerate from small fragments of plant material; however, there remains uncertainty about how much (in terms of mass) rhizome is required for successful regeneration.

Weight loss during medical weight management does not predict weight loss after bariatric surgery: a retrospective cohort study.

Background: Many bariatric surgical centers mandate achieving weight loss targets through medical weight management (MWM) programs before offering bariatric surgery, but the evidence for this is unclear.

Objectives: To examine the relationship between weight changes during (1) MWM, and (2) preoperative low-energy-diet (LED), and weight changes at 12 and 24 months after surgery.

Setting: Multicenter community- and acute-based MWM services referring to one regional bariatric center, United Kingdom.
