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

Double trisomy (48,XXY,+21) in monozygotic twins: case report and review of the literature

The occurrence of double aneuploidy in the same individual is a relatively rare phenomenon. We describe twin newborns with typical clinical features of Down’s syndrome, of which one revealed 48,XXY,+21 GTG-band karyotype. The second newborn died 2 days after its birth, and was clinically diagnosed having Down syndrome. Due to the same clinical features of the twins, the common placenta and amniotic sac, we speculate that they were monozygotics and as a result the second newborn should also be a Klinefelter. The purpose of this report is to present a rare case of possible coincidence of double aneuploidy in newborn twins. A review of the literature showed that double trisomy (48,XXY,+21) in a twin newborn infant has never occurred. (C) 2003 Elsevier SAS. All rights reserved

The oral manifestations of chronic graft-versus-host disease (cGVHD) in paediatric allogeneic bone marrow transplant recipients

The oral manifestations of chronic graft-versus-host disease (cGVHD) in eight allogeneic bone marrow transplant (BMT) paediatric recipients were studied clinically, and lip biopsies were performed in seven of them. A prominent lichenoid reaction was observed in four patients, two with accompanying ulceration. Superficial mucoceles were present in three children. Clinically obvious xerostomia was seen in seven patients. Lip biopsies were positive and correlated with the clinical manifestations. Both clinical and histological findings confirmed the diagnosis of cGVHD. In three additional children, with systemic manifestations indicating cGVHD, the oral mucosa was clinically and histologically normal, and the systemic manifestations were, thus, attributed to drug reactions. The above findings indicate the high value of oral examination in diagnosing or confirming paediatric cGVHD. Superficial mucoceles, reported for the first time in paediatric recipients, seem to be important in the early diagnosis of cGVHD

TREM2 R47H variant and risk for Alzheimer’s disease: assessment in a Greek population and updated meta-analysis

Introduction: Rare coding variants in TREM2 and their association with the susceptibility towards Alzheimer’s disease (AD) were recently studied in various ethnic groups with contradictory results. The T allele of the rs75932628 (p.R47H variant) has shown a positive risk association with AD in several studies; however, neither a study in Greece nor an updated meta-analysis have been conducted. Objective: To assess the association between TREM2 rs75932628 and late-onset (sporadic) AD in a Greek population, and perform a meta-analysis of current data. Materials and Methods: The rs75932628 was genotyped in a total of 327 patients with AD and 700 cognitively healthy controls. A systematic search and meta-analyses of studies presenting data regarding rs75932628 in AD cases and controls were also performed. Results: Three patients vs. none of the controls were found to carry the heterozygous risk allele of the rs75932628, yielding a significant association (p = 0.032), in the Greek sample. In the meta-analysis, the overall odds ratio (OR) under a fixed-effects model was 2.98 (Confidence Interval (CI):2.52–3.53) showing a significant association of the rs75932628-T allele with AD in the overall dataset, based on data from 27 studies (26200 AD cases and 142084controls). Caucasian population-only studies (n = 16) revealed a similar OR of 2.93 (CI:2.45–3.51), whereas Asian population-only studies (n = 5) had a non-significant OR of 0.84 (CI:0.19–3.74). Conclusion: The rs75932628 was associated with AD in the Greek sample. Our meta-analysis, covering a total population of over 168,000 people, also showed a significant association of the allele with AD in Caucasian populations. © 2022 Informa UK Limited, trading as Taylor & Francis Group

Is Carbapenem-resistant Klebsiella pneumoniae Infection in Pediatric Bone Marrow Transplantation Recipients Inevitably Fatal?

Carbapenem resistance, most notably in Klebsiella pneumonia (KPC), results in infections associated with significant morbidity and mortality. Here we report 2 cases of adolescent patients with KPC infection after high-risk bone marrow transplantation, who eventually succumbed from other causes and review the epidemiology and treatment options for KPC infections in this vulnerable population
