Performance of Polyaniline Nanofibers (PANI NFs) as PANI NFs-Silver (Ag) Nanocomposites (NCs) for Energy Storage and Antibacterial Applications

The conductive property of polyaniline nanofibers (PANI NFs) has attracted great attention due to their higher capacitance, high flexibility, low cost, and ease of synthesis. Herewith, it is demonstrated that at room temperature, the template-free synthesized PANI NFs show the properties of PANI NFs–silver nanocomposites (Ag NCs) without a silver precursor with a new physical insight into energy storage devices and antibacterial applications. The diffraction peak at 2θ = 19.1° using X-ray diffraction analysis indicates the silver nature. UV–vis absorption peaks at 408 and 369 nm indicate the silver absorption (HCl-doped). The spectroscopic studies by FTIR, Raman, and NMR indicate that the PANI NFs behave in a similar manner to PANI NFs-Ag NCs with 48.47 S cm–1 conductivity and 570 F g–1 capacitance. Morphological studies by FESEM (size: 50 nm) and HRTEM reveal that the growth of PANI NFs is one-dimensional and more preferable. It also shows higher bacterial inhibition at lower values of minimum inhibitory concentration and minimum bacterial concentration

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)
