About Time: Master Scheduling and Equity

Master schedules are used to structure time, people, resources, and space within a school. This report provides school and district leaders advice about how to use the master schedule to advance equity in their communities. It illuminates ways the schedule can both undermine and advance equity and provides a framework to help schools and districts pivot from technical to strategic scheduling to expand access and opportunity for all student

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

Evaluación del efecto de dos concentraciones de ajo (Allium sativum) con aceite de oliva (Olea europaea) administrado por vía tópica, para el control de Sarcoptes scabiei en perros (Canis lupus familiaris) infestados naturalmente, provenientes de diferentes refugios de la ciudad de Guatemala.

Se evaluó una alternativa natural para el control de Sarcoptes scabiei en perros, que consistió en la mezcla de ajo (Allium sativum) triturado combinado con aceite de oliva (Olea europaea) en dos concentraciones al 15 y al 18% administradas por vía tópica, una vez al día y durante un periodo de 3 semanas consecutivas, a 30 perros diagnostica dos previamente con sarna sarcóptica, provenientes de diferentes refugios de animales de la ciudad capital. Se evaluó la evolución de los pacientes por medio de exámenes clínicos midiendo signos clínicos como prurito, alopecia y eritema y realizando dos raspados cutáneos por semana. Los resultados obtenidos indicaron que, aunque al final del tratamiento no existió una diferencia significati va entre las dos concentraciones de ajo y aceite de oliva evaluadas, al comparar porcentajes de pacientes recuperados y grados de mejoría de signos clínicos, se observo que la concentración al 18% fue más eficaz
