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

Mapping routine measles vaccination in low- and middle-income countries
The safe, highly effective measles vaccine has been recommended globally since 1974, yet in 2017 there were more than 17 million cases of measles and 83,400 deaths in children under 5 years old, and more than 99% of both occurred in low- and middle-income countries (LMICs)(1-4). Globally comparable, annual, local estimates of routine first-dose measles-containing vaccine (MCV1) coverage are critical for understanding geographically precise immunity patterns, progress towards the targets of the Global Vaccine Action Plan (GVAP), and high-risk areas amid disruptions to vaccination programmes caused by coronavirus disease 2019 (COVID-19)(5-8). Here we generated annual estimates of routine childhood MCV1 coverage at 5 x 5-km(2) pixel and second administrative levels from 2000 to 2019 in 101 LMICs, quantified geographical inequality and assessed vaccination status by geographical remoteness. After widespread MCV1 gains from 2000 to 2010, coverage regressed in more than half of the districts between 2010 and 2019, leaving many LMICs far from the GVAP goal of 80% coverage in all districts by 2019. MCV1 coverage was lower in rural than in urban locations, although a larger proportion of unvaccinated children overall lived in urban locations; strategies to provide essential vaccination services should address both geographical contexts. These results provide a tool for decision-makers to strengthen routine MCV1 immunization programmes and provide equitable disease protection for all children.Peer reviewe
Effect of the kappa-casein gene polymorphism, breed and seasonality on physicochemical characteristics, composition and stability of bovine milk Efeito do polimorfismo do gene da kappa-caseína, da raça e da sazonalidade sobre as características físico-químicas, de composição e de estabilidade do leite bovino
The objective of this study was to evaluate the effect of genetic polymorphism of kappa-casein, breed and seasonality on the physicochemical characteristics, composition and stability of milk in commercial dairy herds. A total of 879 milk and blood samples were collected from 603 Holstein and 276 Girolando cows, obtained during rainy and dry seasons. Milk samples were analyzed to determine the physicochemical characteristics, composition and ethanol stability, while blood samples were subjected to polymerase chain reaction to identify the kappa-casein genotype. The frequencies of genotypes AA, AB and BB of k-casein were respectively, 66.83, 31.84 and 1.33% for Holstein, and 71.38, 27.90 and 0.72% for the Girolando cows, respectively. The A allele was more frequent than the B allele, both for Holstein (0.827 and 0.173) and Girolando cows (0.853 and 0.147), respectively. Cows of AB and BB genotypes showed a higher milk fat content compared to the AA genotype. There was an interaction between breed and seasonality on the concentration of milk urea with higher values for Holstein and Girolando cows in the rainy and dry season, respectively. The levels of lactose, total solids, crude protein, true protein, casein and the casein:true protein ratio were higher during the dry season, while during the rainy season, the somatic cell count and milk urea concentration were higher. There was no association between milk stability and k-casein genotypes, but Holstein cows showed higher milk stability than Girolando cows, and milk was more stable during the rainy season than during the dry season.<br>Objetivou-se avaliar o efeito do polimorfismo genético da kappa-caseína, da raça e da sazonalidade sobre as características físico-químicas, a composição e a estabilidade do leite bovino de rebanhos comerciais. Foram coletadas 879 amostras de leite e de sangue de 603 vacas da raça Holandesa e 276 da raça Girolando, obtidas durante as estações seca e chuvosa. As amostras de leite foram analisadas para determinação de características físico-químicas, de composição e de estabilidade ao etanol, e as amostras de sangue foram submetidas à reação em cadeia da polimerase para identificação do genótipo da kappa-caseína. As frequências dos genótipos AA, AB e BB da kappa-caseína foram, respectivamente, de 66,83; 31,84; e 1,33% para a raça Holandesa e 71,38; 27,90; e 0,72% para a Girolando. O alelo A foi mais frequente que o B, tanto para a raça Holandesa (0,827 e 0,173) quanto para a Girolando (0,853 e 0,147). Vacas dos genótipos AB e BB apresentaram maior teor de gordura no leite que as do genótipo AA. Houve interação entre raça e sazonalidade para a concentração de ureia do leite, com maiores concentrações para as raças Holandesa e Girolando, respectivamente, nas estações chuvosa e seca. Os teores de lactose, sólidos totais, proteína bruta, proteína verdadeira e caseína e a relação caseína/proteína verdadeira foram maiores durante o período seco, enquanto, durante a estação chuvosa, a contagem de células somáticas e os teores de nitrogênio ureico no leite foram maiores. Não houve associação entre a estabilidade do leite e os genótipos da kappacaseína, no entanto, o leite de vacas Holandesas é mais estável que o de vacas Girolando e, durante a estação chuvosa, apresenta maior estabilidade que na estação seca
