    Green synthesis is an eco-friendly approach that provides a viable alternative to traditional physical and chemical methods for the production of nanoparticles. This technique employs non-toxic and safe materials, such as plants, microorganisms, algae, bacteria, yeast, and fungi, to generate stable and less toxic nanoparticles. Citrus sinensis, commonly known as sweet orange, is a plant that contains various active compounds. These bioactive compounds can be extracted and used as bioreductants in green synthesis of nanoparticles. This mini review aimed to provide an overview of the current state of research on the utilization of Citrus sinensis as a bioreductant in the production of nanoparticles. A systematic search strategy was employed to identify research articles that met the criteria of discussing green synthesis of nanoparticles with Citrus sinensis as a bioreductant. The nanoparticles produced using Citrus sinensis extract can be either metal nanoparticles or metal oxide nanoparticles. The review highlights the distribution of nanoparticles produced with Citrus sinensis extract, their applications, and the extraction process of Citrus sinensis commonly employed in green synthesis of nanoparticles. Hopefully this review serves as a useful reference for researchers and practitioners who are interested in employing the Citrus sinensis plant as a bioreductant in the green synthesis of nanoparticles

    Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

    Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
