Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Ecuación estructural en el análisis de la multimorbilidad en niños de primera infancia afiliados a la entidad promotora de salud compensar Bogotá, Colombia. 2017-2018

El estudio permitió identificar patrones de multimorbilidad en los niños de la primera infancia en edades comprendidas entre 0 y 5 años afiliados a la Entidad Promotora de Salud (EPS) Compensar en Colombia en los años 2017 y 2018 orientado a redefinir los programas de gestión de los riesgos en salud de este grupo de menores. Se realizó un estudio de corte transversal retrospectivo que contó con una población inicial de 130.707 niños de los cuales 85.449 (65.4%) cumplieron con el criterio de multimorbilidad. El 52% de los niños fueron de sexo masculino y la mayoría residían en la ciudad de Bogotá (capital de Colombia). Los patrones de multimorbilidad fueron identificados mediante un análisis jerárquico de clústeres descrito por sexo, edad, ciudad de residencia, plan de atención y diagnóstico principal y relacionados se identificaron cinco conglomerados de niños con características homogéneas y diferenes entre sí. Las enfermedades comunes a varios de los clústeres fueron el resfriado común y la rinitis alérgica, la dermatitis, la diarrea infecciosa o de origen presuntamente infeccioso y la caries de la dentina, todas estas propias de la morbilidad de esta primera etapa de la vida. Dentro de las enfermedades crónicas se encontraron el Asma y la obesidad, así como las afectaciones del desarrollo del habla y del lenguaje, y perturbacion de la actividad y de la atención, también se evidenciaron menores expuestos a negligencia o abandono. Respecto a los costos, el clúster 5 es el que presenta el mayor costo promedio tanto para las atenciones del plan de beneficios como del plan de atención complementaria. Como conclusión, la presencia de transtornos físicos y mentales requiere redefinir las intervenciones de salud pública, y virar hacia servicios de salud de mayor integralidad, en el que participen disciplinas médicas y no médicas, y de las ciencias sociales o de humanidades, así como otros sectores diferentes a salud, que permitan ampliar el espectro de conocimiento de los menores y sus familias como parte del entendimiento de los patrones de multimorbilidad observados y reorientar los servicios de salud hacia la gestión socio sanitaria.Magíster en EpidemiologíaMaestrí

Gender differences and management of stroke risk of nonvalvular atrial fibrillation in an upper middle-income country: Insights from the CARMEN-AF registry

Background: Atrial Fibrillation (AF) is associated with an increased risk of stroke and systemic embolism. Several studies have suggested that female AF patients could have a greater risk for stroke. There is scarce information about clinical characteristics and use of antithrombotic therapies in Latin American patients with nonvalvular AF. Objective: To describe the gender differences in clinical characteristics, thromboembolic risk, and antithrombotic therapy of patients with nonvalvular AF recruited in Mexico, an upper middle-income country, into the prospective national CARMEN-AF Registry. Methods: A total of 1423 consecutive patients, with at least one thromboembolic risk factor were enrolled in CARMEN-AF Registry during a three-year period (2014–2017). They were categorized according to Gender. Results: Overall, 48.6% were women, mean age 70 ± 12 years. Diabetes, smoking, alcoholism, non-ischemic cardiomyopathy, coronary artery disease, and obstructive sleep apnea were higher in men. Most women were found with paroxysmal AF (40.6%), and most men with permanent AF (44.0%). No gender differences were found in the use of vitamin K antagonists (VKA) (30.5% in women vs. 28.0% in men). No gender differences were found in the use of direct oral anticoagulants (DOAC) (33.8% women vs 35.4% men). Conclusions: CARMEN-AF Registry demonstrates that in Mexico, regardless of gender, a large proportion of patients remain undertreated. No gender differences were found in the use of VKA or DOAC. Keywords: Atrial fibrillation, Gender, Thromboembolic risk, Antithrombotic therapy, Stroke, Mexic

Coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at √sNN=2.76 TeV

The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at sNN=2.76 TeV. The J/ψ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 μb−1. The cross section for coherent J/ψ production in the rapidity interval −3.6<y<−2.6 is measured to be dσJ/ψcoh/dy=1.00±0.18(stat)−0.26+0.24(syst) mb. The result is compared to theoretical models for coherent J/ψ production and found to be in good agreement with those models which include nuclear gluon shadowing

Multi-strange baryon production in pp collisions at √s=7 TeV with ALICE

A measurement of the multi-strange Ξ− and Ω− baryons and their antiparticles by the ALICE experiment at the CERN Large Hadron Collider (LHC) is presented for inelastic proton–proton collisions at a centre-of-mass energy of 7 TeV. The transverse momentum (pT) distributions were studied at mid-rapidity (|y|6.0 GeV/c. We also illustrate the difference between the experimental data and model by comparing the corresponding ratios of (Ω−+Ω¯+)/(Ξ−+Ξ¯+) as a function of transverse mass
