Objectives To evaluate whether the revascularization of a coronary chronic total occlusion in an infarct-related artery (IRACTO) may be associated with lower recurrence of ventricular arrhythmias (VA) among patients with a secondary prevention implantable cardioverter defibrillator (ICD). Background IRACTO is increasingly recognized as an independent predictor of VA. It is unknown whether IRACTO revascularization can reduce the burden of VA. Methods Multicenter observational cohort study that included consecutive patients with prior myocardial infarction and secondary prevention ICD. The primary endpoint was any appropriate ICD therapy. Results Among the 460 patients included, 269 (58%) had at least one IRACTO at the coronary angiogram performed before ICD implantation; of these, 20 (7%) had their IRACTO successfully revascularized (IRACTO-R) afterwards. During a median follow-up of 48 months, 229 patients (49%) had at least one appropriate ICD therapy. Patients with IRACTO not revascularized (IRACTO-NR) had the highest incidence of ICD therapies (65%) while patients with IRACTO-R had the lowest (10%, p less then .001). In the entire cohort, IRACTO-NR was an independent predictor of appropriate ICD therapies (HR 2.85, p less then .001) and appropriate ICD shocks (HR 2.94, p less then .001). Among patients with IRACTO at baseline, IRACTO-R was independently associated with a marked reduction of appropriate ICD therapies (HR 0.12, p = .002) and appropriate ICD shocks (HR 0.21, p = .03). Conclusions In patients with prior myocardial infarction and secondary prevention ICD, IRACTO revascularization was independently associated with a markedly lower incidence of appropriate ICD therapies and shocks. These results should be corroborated by larger prospective studies.Objective To assess the value of respiratory rate (RR) as a predictor of clinical deterioration in children, compared with other vital sign measurements. Design A retrospective case-control study, comparing children who deteriorated, requiring admission to critical care with children who did not deteriorate. Methods RR, heart rate (HR), and blood pressure (BP) measurements were collected from each patient for a 48-hour duration. The 95th centile was identified for each and 5% to 30% thresholds above the 95th centile were calculated. For each threshold the sensitivity, specificity, odds ratio, positive, and negative predictive value for deterioration was calculated. Results Forty cases (age range 7 weeks-15 years) and 40 control patients matched for age, gender, and hospital location were recruited. In 30/40 patients who deteriorated at least one RR ≥ 30% above the 95th centile for their age was recorded in the 48 hours before deterioration, compared with 10/40 controls, regardless of clinical diagnosis. Only 3/40 children that deteriorated had a HR > 30% greater than the 95th centile, compared with 2/40 controls. An elevated RR was the only vital sign whose odds ratios were significant at each threshold level above the 95th centile. Maximum RR occurred 16.8 hours before deterioration. Conclusion RR is a more accurate predictor of clinical deterioration in children than other vital signs. Greater weighting and importance should be placed on RR, which is often omitted in children due to difficulties with its measurement.Objective The coronavirus disease 2019 (COVID-19) pandemic is disrupting health services worldwide. We aimed to evaluate the provision of obstetrics and gynaecology services in the UK during the acute phase of the COVID-19 pandemic. Design Interview-based national survey. Setting Women's healthcare units in the National Health Service. Population Junior doctors in obstetrics and gynaecology. Methods Participants were interviewed by members of the UK Audit and Research in Obstetrics and Gynaecology trainees' collaborative between 28 March and 7 April 2020. We used a quantitative analysis for closed-ended questions and a thematic framework analysis for open comments. Results We received responses from 148/155 units (95%), most of the participants were in years 3-7 of training (121/148, 82%). Most completed specific training drills for managing obstetric and gynaecological emergencies in women with COVID-19 (89/148, 60.1%) and two-person donning and doffing of Personal Protective Equipment (PPE) (96/148, 64.9%).ccess to care in the long term.The most frequent cancer worldwide is skin cancer, occurring at epidemic rates in countries exposed to high levels of chronic ultraviolet radiation such as Australia and New Zealand (ANZ). Australia has the highest incidence of non‐melanoma skin cancer (NMSC) in the world. NMSC is predominantly a cancer of the middle aged or elderly and accounts for considerable consulting and treatment time in most radiation oncology departments. Many patients also suffer from medical co‐morbidity, an important factor in any treatment decision.The recent demand for fluorescent labeled materials (FLMs) in forensic security concepts such as latent fingerprints (LFs) that encodes information for anti-counterfeiting and encryption of confidential data makes necessary the development of building new and innovative materials. Here, novel FLMs based on Polyhedral Oligomeric Silsesquioxanes (POSS) functionalized with fluorophores via "click" reactions have been successfully synthesized and fully characterized. selleck A comprehensive study of their photophysical properties has displayed large Stokes's shift together with good photostability in all cases, fulfilling the fundamental requisites for any legible LF detection on various surfaces. The excellent performance of the hetero-bifunctional FLM in the visualization of LF is emphasized by their legibility, selectivity, sensitivity and temporal photostability. In this study, development mechanisms have been proposed and the overall concept constitute a novel approach for vis-à-vis forensic investigations to trace an individual's identity.High capacity metal oxide conversion anodes for lithium-ion batteries (LIBs) are primarily limited by their poor reversibility and cycling stability. Herein, we report a promising approach to improve the electrochemical performance of a MoO 2 anode via direct fluorination of the prelithiated MoO 2 . The fluorinated anode contains a mixture of crystalline MoO 2 and amorphous molybdenum oxyfluoride phases as determined from a suite of characterization methods including X-ray diffraction (XRD), Raman spectroscopy, and X-ray photoelectron spectroscopy, and scanning transmission electron microscopy (STEM). Electrochemical measurements indicate that fluorination facilitates the conversion reaction kinetics, which leads to increased capacity, higher coulombic efficiency, and better cycling stability as compared to the non-fluorinated samples. These results suggested that the fluorination after prelithiation not only favors the formation of the oxyfluoride phase but also improves the lithium-ion diffusivity, and reversibility of the conversion reaction, making it an attractive approach to address the problems of conversion electrodes.
