Unlabelled: In this brief report, we present the findings of a survey which explores the learning curve that was achieved during the 'Serial Lung Ultrasound in predicting the need for surfactant and Respiratory course in Preterm infants' (SLURP) study. The aim of this survey was to evaluate the training lung ultrasound operators received in order to scan patients who were recruited into the SLURP study. The aim of the SLURP study was to validate the optimal lung ultrasound (LU) 'cut off' score using standard and extended LU zones that predict surfactant need in babies born ≤ 34 weeks on non-invasive respiratory support when clinicians had various levels of experience in LU.

Methods: Online databases were searched for studies evaluating different closure systems for gastrointestinal defects.
Background/aims: Self-expanding metallic stents (SEMS) are an alternative to emergency surgery (ES) for malignant colorectal obstruction. This study aimed to compare surgical outcomes between SEMS as a bridge to surgery (BTS) and ES in patients with malignant colorectal obstruction.
Methods: A comprehensive database search was conducted until October 2023 to compare outcomes between SEMS as a BTS and ES.
Background: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is a common surgical procedure for ulcerative colitis and familial adenomatous polyposis. IPAA strictures are a known complication, often requiring surgical intervention. Endoscopic interventions offer a less invasive alternative, but their safety and efficacy remain uncertain.

- Superhydrophobic surfaces with hierarchical micro/nanostructures, like the developed O-Ph-POSS on fluorinated graphene, achieve high water contact angles (152°) and low surface energy (5.6 mJ/m²), making them highly robust and effective in water-repelling applications.
- The O-Ph-POSS-FG hybrid demonstrated remarkable oil absorption (200-500 wt%) and was successfully used to coat polyurethane sponges, achieving oil-water separation efficiencies of 90%-99%, even after multiple cycles.
- Durability tests showed that the sponges maintained superhydrophobic properties over time, retaining effective water contact angles and separation efficiency after one year and multiple mechanical stress tests.
