    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

    Understanding how nutrients accumulate and change throughout the developmental stages according to the BBCH scale can be a very effective technique for developing fertilization programmes for high-quality, marketable grape production. Accordingly, the macro- and micronutrient concentrations at different growth stages were analyzed for two commercial grape cultivars, viz., “Anab-e-Shahi” and “Perlette”, by using an extended BBCH scale. The results show nitrogen content was reduced during the sampling period (D1 to D6) from 1.76 percent to 1.09 percent. Potassium concentration in developing berries kept on increasing from 0.15%, at principal growth stage 7 with BBCH code 73 (D1), to 0.26% at principal growth stage 8 code 89 (D6). The lowest phosphorus content of 253.88 ppm and the highest of 338.43 ppm were found in growth stages D1 and D6, respectively. The berry Ca however showed an increase first and thereafter decreased to 225.18 ppm at harvest. Mg content also recorded a similar trend from stages D1 to D6 of the BBCH scale and decreased to 116.08 ppm at D6. B and Cu concentrations increased from D1 to D6, and Mn and Zn increased first and decreased thereafter until harvest. No specific trend was recorded in Fe concentration. The concentration of nutrients in berries at different developmental stages can be used as the standard reference for growing berries using proper fertilization
