    The structural properties and binding motif of a strongly sigma-electron donating N-heterocyclic carbene are investigated on different transition metal surfaces. The examined cyclic (alkyl)(amino) carbene (CAAC) is found to be mobile on surfaces and molecular islands with short-range order could be found at high coverage. By combining scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) calculations our study highlights how CAACs bind to the surface, which is of tremendous importance to gain understanding for heterogeneous catalysts bearing CAACs as ligands. © 2020 WILEY-VCH Verlag GmbH & Co.

However, the construction of a stable π-stacked structure in a polymer is considerably challenging, because it requires sophisticated designs and precise synthetic methods. Herein, we present a novel π-stacked architecture based on poly(quinolylene-2,3-methylene), bearing alanine derivatives as the side chain, obtained through the living cyclocopolymerization of an o -allenylaryl isocyanide. In the resulting polymer, the neighboring quinoline rings of the main chain form a layered structure with π-π interactions, which is stabilized by intramolecular hydrogen bonds. The vicinal quinoline units form two independent helices and the whole molecule is a twisted tape structure. This structure is established on the basis of UV/CD spectra, theoretical calculations, and atomic force microscopy. © 2020 WILEY-VCH Verlag GmbH & Co.

We compared the success and reliability of laparoscopic repair of intraperitoneal bladder rupture in patients who had undergone total laparoscopic hysterectomy. METHODS This retrospective study included patients who underwent total laparoscopic hysterectomy for benign gynaecological cases at a tertiary academic hospital between January 2018 and June 2019. All patient medical records included in the study were reviewed, and the causes, incidence and management of bladder injuries were assessed. RESULTS There were nine patients. The cause of all the ruptures was iatrogenic, and all were intra-operatively detected. In all patients, bladder injuries occurred in the posterior side of the bladder during vesicouterine dissection. Laparoscopic bladder perforation repair was performed successfully in all patients. No major complications had occurred in any patients after surgery. The foley catheters were removed 6.67 ± 0.7 (5-7) days after surgery. CONCLUSIONS If performed by well-trained laparoscopic surgeons, laparoscopic hysterectomy could be the best option for appropriate patients. Nevertheless, patients should be well aware of the potential complications in endometriosis and caesarean cases before the procedure, and care should be paid during dissection. When a urogenital injury is suspected or detected the condition must be adequately identified and proper treatment must be performed to avoid postoperative complications and long-term morbidity. © 2020 John Wiley & Sons Ltd.Promoting and retaining junior faculty are major challenges for many medical schools. High clinical workloads often limit time for scholarly projects and academic development, especially in anesthesiology. To address this, we created the East/West Visiting Scholars in Pediatric Anesthesia Program (ViSiPAP). The program’s goal is to help “jumpstart” academic careers by providing opportunities for national exposure and recognition through invited lectures and collaborative opportunities. East/West ViSiPAP benefits the participating scholars, the home and hosting anesthesia departments, and pediatric anesthesia fellowship training programs. By fostering a sense of well-being and inclusion in the pediatric anesthesia community, East/West ViSiPAP has the potential to increase job satisfaction, help faculty attain promotion and reduce attrition. Faculty and trainees are exposed to new expertise and role models. Moreover, ViSiPAP provides opportunities for women and underrepresented in medicine faculty. This program can help develop today’s junior faculty into tomorrow’s leaders in pediatric anesthesia. We advocate for expanding the concept of ViSiPAP to other institutions in academic medicine.

It has now spread rapidly to over 190 countries and territories around the world and has been declared a global pandemic by the World Health Organization. The virus is spread through droplet transmission and currently has a mortality rate of over 4% globally. The pediatric population has been found to be less susceptible to the disease with the majority of children having milder symptoms and only one pediatric death being reported globally so far. BI3231 Despite this, strategies need to be put in place to prevent further spread of the virus. We present a summary of the general measures implemented at a large adult and pediatric tertiary hospital in Singapore (National University Hospital) as well as the specific strategies in place for the operating room and pediatric intensive care unit.

We conducted a preliminary survey to investigate whether people with dystonia experience falls and to identify contributing factors to falls in this population. METHODS An online survey of people with dystonia was conducted in November 2015. Respondents were asked to complete demographic information, three questionnaires (the Falls Self-Efficacy Scale International [FES-I], the Activities-based Balance Confidence Scale [ABC] and the Functional Disability Questionnaire [FDQ]), and to report any falls sustained during the previous 6 months. RESULTS Thirty-nine percent of the 122 respondents reported falling in the previous 6 months and 65% of fallers were diagnosed with dystonia not affecting the lower limbs. Fallers reported lower falls self-efficacy and balance confidence with higher functional disability. Both falling scales correlated with self-reported functional disability. Linear regression analysis for falls prediction revealed the variables FES-I and FDQ accounted for almost 30% of the falls in this dystonia population.
