AbstractAlthough stem cell-based therapy has demonstrated considerable potential to manage certain diseases more successfully than conventional surgery, it nevertheless comes with inescapable drawbacks that might limit its clinical translation. Compared to stem cells, stem cell-derived exosomes possess numerous advantages, such as non-immunogenicity, non-infusion toxicity, easy access, effortless preservation, and freedom from tumorigenic potential and ethical issues. Exosomes can inherit similar therapeutic effects from their parental cells such as embryonic stem cells and adult stem cells through vertical delivery of their pluripotency or multipotency. After a thorough search and meticulous dissection of relevant literature from the last five years, we present this comprehensive, up-to-date, specialty-specific and disease-oriented review to highlight the surgical application and potential of stem cell-derived exosomes. Exosomes derived from stem cells (e.g., embryonic, induced pluripotent, hematopoietic, mesenchymal, neural, and endothelial stem cells) are capable of treating numerous diseases encountered in orthopedic surgery, neurosurgery, plastic surgery, general surgery, cardiothoracic surgery, urology, head and neck surgery, ophthalmology, and obstetrics and gynecology. The diverse therapeutic effects of stem cells-derived exosomes are a hierarchical translation through tissue-specific responses, and cell-specific molecular signaling pathways. In this review, we highlight stem cell-derived exosomes as a viable and potent alternative to stem cell-based therapy in managing various surgical conditions. We recommend that future research combines wisdoms from surgeons, nanomedicine practitioners, and stem cell researchers in this relevant and intriguing research area.

Objective To quantify the environmental impact of personal protective equipment (PPE) distributed for use by the health and social care system to control the spread of SARS-CoV-2 in England, and model strategies for mitigating the environmental impact. Design Life cycle assessment was used to determine environmental impacts of PPE distributed to health and social care in England during the first six months of the COVID-19 pandemic. The base scenario assumed all products were single-use and disposed of via clinical waste. Scenario modelling was used to determine the effect of environmental mitigation strategies: (1) eliminating international travel during supply; (2) eliminating glove use; (3) reusing gowns and face shields; and (4) maximal recycling. Setting Royal Sussex County Hospital, Brighton, UK. Main outcome measures The carbon footprint of PPE distributed during the study period totalled 106,478 tonnes CO2e, with greatest contributions from gloves, aprons, face shields and Type IIR surgical masks. The estimated damage to human health was 239 DALYs (disability-adjusted life years), impact on ecosystems was 0.47 species.year (loss of local species per year), and impact on resource depletion was costed at US $12.7m (GBP £9.3m). Scenario modelling indicated UK manufacture would have reduced the carbon footprint by 12%, eliminating gloves by 45%, reusing gowns and gloves by 10% and maximal recycling by 35%. Results A combination of strategies may have reduced the carbon footprint by 75% compared with the base scenario, and saved an estimated 183 DALYS, 0.34 species.year and US $7.4m (GBP £5.4m) due to resource depletion. Conclusion The environmental impact of PPE is large and could be reduced through domestic manufacture, rationalising glove use, using reusables where possible and optimising waste management.

The scale of the COVID-19 pandemic means that a significant number of patients who have previously been infected with SARS-CoV-2 will require surgery. Given the potential for multisystem involvement, timing of surgery needs to be carefully considered to plan for safe surgery. This consensus statement uses evidence from a systematic review and expert opinion to highlight key principles in the timing of surgery. Shared decision-making regarding timing of surgery after SARS-CoV-2 infection must account for severity of the initial infection; ongoing symptoms of COVID-19; comorbid and functional status; clinical priority and risk of disease progression; and complexity of surgery. For the protection of staff, other patients and the public, planned surgery should not be considered during the period that a patient may be infectious. Precautions should be undertaken to prevent pre- and peri-operative infection, especially in higher risk patients. Elective surgery should not be scheduled within 7 weeks of a diagnosis of SARS-CoV-2 infection unless the risks of deferring surgery outweigh the risk of postoperative morbidity or mortality associated with COVID-19. SARS-CoV-2 causes either transient or asymptomatic disease for most patients, who require no additional precautions beyond a 7-week delay, but those who have persistent symptoms or have been hospitalised require special attention. Patients with persistent symptoms of COVID-19 are at increased risk of postoperative morbidity and mortality even after 7 weeks. The time before surgery should be used for functional assessment, prehabilitation and multidisciplinary optimisation. Vaccination several weeks before surgery will reduce risk to patients and might lessen the risk of nosocomial SARS-CoV-2 infection of other patients and staff. National vaccine committees should consider whether such patients can be prioritised for vaccination. As further data emerge, these recommendations may need to be revised, but the principles presented should be considered to ensure safety of patients, the public and staff.

For a population with knee osteoarthritis (OA), determine: 1) the prevalence of single compartmental, bicompartmental and tricompartmental OA, 2) the prevalence of isolated medial tibiofemoral, lateral tibiofemoral, or patellofemoral OA, and combinations thereof.PubMed and Web of Science databases, and reference lists of identified studies, were searched to find studies which reported on the compartmental distribution and prevalence of knee OA. Two independent reviewers assessed studies against pre-defined inclusion criteria and prevalence data were extracted along with subject characteristics. The methodological quality of each included study was assessed. A random-effects model meta-analysis was performed for each OA category to estimate the relative prevalence of OA in the knee compartments amongst people with knee OA.16 studies (3,786 knees) met the inclusion criteria. High heterogeneity was measured. Normalised for knees with OA, estimated prevalence rates (95% CI) were: single compartmental 50% (31.5-58.3%), bicompartmental 33% (23.1-37.2%) and tricompartmental only 17% (8.8-24.8%). Isolated medial tibiofemoral OA, isolated patellofemoral OA, and combined medial tibiofemoral and patellofemoral OA were more common than tricompartmental disease, occurring in 27% (15.2-31.1%), 18% (9.9-22.7%) and 23% (14.1-27.3%) of people respectively. Single/bicompartmental patterns of disease involving the lateral tibiofemoral compartment were less common, summing to 15% (8.5-18.7%).Three-quarters of people with knee OA do not have tricompartmental disease. This is not reflected in the frequency with which partial and combined partial knee arthroplasties are currently used.PROSPERO systematic review protocol (CRD42019140345).

Objectives To assess the complications of transrectal (TR) compared to transperineal prostate (TP) biopsies. Patients and Methods Men diagnosed with prostate cancer between 1 April 2014 and 31 March 2017 in England were identified in the National Prostate Cancer Audit. Administrative hospital data were then used to categorize the type of prostate biopsy and subsequent complications requiring hospital admission. Administrative hospital data were used to identify patients staying overnight immediately after biopsy and those readmitted separately for hospital admissions because of sepsis, urinary retention or haematuria. Procedure-related mortality and total length of hospital stay within 30 days were also recorded. Generalized linear models were used to calculate adjusted risk differences (aRDs). Results A total of 73 630 patients undergoing prostate biopsy were identified. Those undergoing TP biopsy (n = 13 723) were more likely to have an overnight hospital stay (12.3% vs 2.4%; aRD 9.7%, 95% confidence interval [CI] 7.1–12.3), were less likely to be readmitted because of sepsis (1.0% vs 1.4%; aRD −0.4%, CI −0.6 to −0.2), and were more likely to be readmitted with urinary retention (1.9% vs 1.0%; aRD 1.1%, CI 0.7–1.4) than those undergoing a TR biopsy (n = 59 907). There were no significant differences in the risk of haematuria or mortality. Conclusions Our results showed that TP biopsy had a lower risk of readmission for sepsis but a higher risk of readmission for urinary retention than TR biopsy. Use of the TP route would prevent one readmission for sepsis in 278 patients at the cost of three additional patients readmitted for urinary retention.

The association of workplace factors on mental health of healthcare workers (HCWs) during the COVID-19 pandemic needs to be urgently established. This will enable governments and policy-makers to make evidence-based decisions. This international study reports the association between workplace factors and the mental health of HCWs during the pandemic. An international, cross-sectional study was conducted in 41 countries. The primary outcome was depressive symptoms, derived from the validated Patient Health Questionnaire-2 (PHQ-2). Multivariable logistic regression identified factors associated with mental health outcomes. Inter-country differences were also evaluated. A total of 2527 responses were received, from 41 countries, including China (n = 1213; 48.0%), UK (n = 891; 35.3%), and USA (n = 252; 10.0%). Of all participants, 1343 (57.1%) were aged 26 to 40 years, and 2021 (80.0%) were female; 874 (34.6%) were doctors, and 1367 (54.1%) were nurses. Factors associated with an increased likelihood of depressive symptoms were: working in the UK (OR = 3.63; CI = [2.90–4.54]; p < 0.001) and USA (OR = 4.10; CI = [3.03–5.54]), p < 0.001); being female (OR = 1.74; CI = [1.42–2.13]; p < 0.001); being a nurse (OR = 1.64; CI = [1.34–2.01]; p < 0.001); and caring for a COVID-19 positive patient who subsequently died (OR = 1.20; CI = [1.01–1.43]; p = 0.040). Workplace factors associated with depressive symptoms were: redeployment to Intensive Care Unit (ICU) (OR = 1.67; CI = [1.14–2.46]; p = 0.009); redeployment with perceived unsatisfactory training (OR = 1.67; CI = [1.32–2.11]; p < 0.001); not being issued with appropriate personal protective equipment (PPE) (OR = 2.49; CI = [2.03–3.04]; p < 0.001); perceived poor workplace support within area/specialty (OR = 2.49; CI = [2.03–3.04]; p < 0.001); and perceived poor mental health support (OR = 1.63; CI = [1.38–1.92]; p < 0.001). This is the first international study, demonstrating that workplace factors, including PPE availability, staff training pre-redeployment, and provision of mental health support, are significantly associated with mental health during COVID-19. Governments, policy-makers and other stakeholders need to ensure provision of these to safeguard HCWs’ mental health, for future waves and other pandemics.

Abstract Background The aim of this study was to estimate the carbon footprint and financial cost of decontaminating (steam sterilization) and packaging reusable surgical instruments, indicating how that burden might be reduced, enabling surgeons to drive action towards net-zero-carbon surgery. Methods Carbon footprints were estimated using activity data and prospective machine-loading audit data at a typical UK in-hospital sterilization unit, with instruments wrapped individually in flexible pouches, or prepared as sets housed in single-use tray wraps or reusable rigid containers. Modelling was used to determine the impact of alternative machine loading, opening instruments during the operation, streamlining sets, use of alternative energy sources for decontamination, and alternative waste streams. Results The carbon footprint of decontaminating and packaging instruments was lowest when instruments were part of sets (66–77 g CO2e per instrument), with a two- to three-fold increase when instruments were wrapped individually (189 g CO2e per instrument). Where 10 or fewer instruments were required for the operation, obtaining individually wrapped items was preferable to opening another set. The carbon footprint was determined significantly by machine loading and the number of instruments per machine slot. Carbon and financial costs increased with streamlining sets. High-temperature incineration of waste increased the carbon footprint of single-use packaging by 33–55 per cent, whereas recycling reduced this by 6–10 per cent. The absolute carbon footprint was dependent on the energy source used, but this did not alter the optimal processes to minimize that footprint. Conclusion Carbon and financial savings can be made by preparing instruments as part of sets, integrating individually wrapped instruments into sets rather than streamlining them, efficient machine loading, and using low-carbon energy sources alongside recycling.

Hybrid surgical instruments contain both single-use and reusable components, potentially bringing together advantages from both approaches. The environmental and financial costs of such instruments have not previously been evaluated. We used Life Cycle Assessment to evaluate the environmental impact of hybrid laparoscopic clip appliers, scissors, and ports used for a laparoscopic cholecystectomy, comparing these with single-use equivalents. We modelled this using SimaPro and ReCiPe midpoint and endpoint methods to determine 18 midpoint environmental impacts including the carbon footprint, and three aggregated endpoint impacts. We also conducted life cycle cost analysis of products, taking into account unit cost, decontamination, and disposal costs. The environmental impact of using hybrid instruments for a laparoscopic cholecystectomy was lower than single-use equivalents across 17 midpoint environmental impacts, with mean average reductions of 60%. The carbon footprint of using hybrid versions of all three instruments was around one-quarter of single-use equivalents (1756 g vs 7194 g CO2e per operation) and saved an estimated 1.13 e−5 DALYs (disability adjusted life years, 74% reduction), 2.37 e−8 species.year (loss of local species per year, 76% reduction), and US $ 0.6 in impact on resource depletion (78% reduction). Scenario modelling indicated that environmental performance of hybrid instruments was better even if there was low number of reuses of instruments, decontamination with separate packaging of certain instruments, decontamination using fossil-fuel-rich energy sources, or changing carbon intensity of instrument transportation. Total financial cost of using a combination of hybrid laparoscopic instruments was less than half that of single-use equivalents (GBP £131 vs £282). Adoption of hybrid laparoscopic instruments could play an important role in meeting carbon reduction targets for surgery and also save money.

The impact of vaccination and new SARS-CoV-2 variants on peri-operative outcomes is unclear. We aimed to update previously published consensus recommendations on timing of elective surgery after SARS-CoV-2 infection to assist policymakers, administrative staff, clinicians and patients. The guidance remains that patients should avoid elective surgery within 7 weeks of infection, unless the benefits of doing so exceed the risk of waiting. We recommend individualised multidisciplinary risk assessment for patients requiring elective surgery within 7 weeks of SARS-CoV-2 infection. This should include baseline mortality risk calculation and assessment of risk modifiers (patient factors; SARS-CoV-2 infection; surgical factors). Asymptomatic SARS-CoV-2 infection with previous variants increased peri-operative mortality risk three-fold throughout the 6 weeks after infection, and assumptions that asymptomatic or mildly symptomatic omicron SARS-CoV-2 infection does not add risk are currently unfounded. Patients with persistent symptoms and those with moderate-to-severe COVID-19 may require a longer delay than 7 weeks. Elective surgery should not take place within 10 days of diagnosis of SARS-CoV-2 infection, predominantly because the patient may be infectious, which is a risk to surgical pathways, staff and other patients. We now emphasise that timing of surgery should include the assessment of baseline and increased risk, optimising vaccination and functional status, and shared decision-making. While these recommendations focus on the omicron variant and current evidence, the principles may also be of relevance to future variants. As further data emerge, these recommendations may be revised.

ObjectivesThis study aimed to determine the clinical utility of the androgen deprivation therapy (ADT)+docetaxel (DOCE)+androgen receptor-targeted agent (ARTA) triplet therapy in patients with metastatic hormone-sensitive prostate cancer (mHSPC) in the UK.DesignA modified Delphi method. A steering group of eight UK healthcare professionals experienced in prostate cancer care discussed treatment challenges, developing 39 consensus statements across four topics. Agreement with the statements was tested with a broader panel of professionals within this therapeutic area in the UK through an anonymous survey, using a four-point Likert scale. This was distributed by the steering group members and an independent third party. Following the survey, the steering group convened to discuss the results and formulate recommendations.SettingThe steering group convened online for discussions. The survey was distributed via email by the clinicians and the independent third party.ParticipantsHealthcare professionals involved in the provision of prostate cancer care, working in relevant professional roles (oncology, urology or geriatric consultant, oncology nurse specialist, and hospital pharmacist) within the UK. No patients or members of the public were involved within the study.InterventionsNone.Primary and secondary outcome measuresConsensus was defined as high (≥75% agreement) and very high (≥90% agreement).ResultsResponses were received from 120 healthcare professionals, including oncologists (n=73), urologists (n=16), geriatricians (n=15), nurse specialists (n=11) and hospital pharmacists (n=5). Consensus was reached for 37 out of 39 (95%) statements, and 27/39 (69%) statements achieved very high agreement ≥90%. Consensus was not reached for 2/39 (5%) statements.ConclusionsBased on the consensus observed, the steering group developed a set of recommendations for the clinical utility of ADT+DOCE+ARTA in treating patients with mHSPC in the UK. Following these recommendations enables clinicians to identify appropriate patients with mHSPC for triplet treatment, thereby improving patients’ outcomes.

Abstract Background Symptomatic gallstones are the most common reason for evaluation by an Emergency General Surgery (EGS) service, with laparoscopic cholecystectomy (LC) being performed by most general surgeons. Previous studies show that most LCs in the United Kingdom (UK) are performed by colorectal surgeons (CR). Emergency cholecystectomy requires advanced skills including intra-operative assessment of the bile ducts, and the ability to perform intra-operative cholangiogram (IOC) is part of the procedure-based assessment (PBA) that evidences competency for certificate of completion of training (CCT). This study aims to assess documented evidence of competency in benign biliary surgery amongst general surgeons in the UK. Method PBAs relating to LC and CBD exploration (CBDE) were retrieved for all UK general surgeons who received CCT between 2016 and 2021 from ISCP (702; 285 (41%) colorectal; 212 (30%) Upper GI (UGI)). All eLogbook entries relating to LC +/- IOC +/- CBDE were also retrieved. Subspecialty interest was determined from Part 2 of the FRCS examination. Competence (Level 4) as well as a granular assessment of IOC and CBDE was compared amongst trainees, taking into account their subspecialty interest. Results 11,733 LC and 553 CBDE assessments from 160,570 LC +/- IOC +/- CBDE procedures recorded on eLogbook were retrieved. Knowledge of IOC indication was assessed in 467 (94%) surgeons, but performance was only assessed in 380 (75%) surgeons. Median satisfactory IOC performance assessments was 3 (2-5). UGI were more likely to do this than colorectal (4 (2-7) vs 2 (1-4) P &lt; 0.001). Satisfactory CBDE was achieved by 86 surgeons (12 CR and 74 UGI). 486 surgeons (97% CR; 94% UGI) received Level 4 (independence) despite never achieving satisfactory ability to perform IOC. Conclusion Competency in acute biliary surgery for general surgeons at certification is extensively assessed using PBAs. Cholecystectomy training and assessment in the UK does not seem to include intraoperative bile duct anatomy assessment or treatment of CBD stones. Assumed competency in cholecystectomy by trainers in the UK does not seem to include the need to do this, as 97% of CR and 94% of UGI trainees achieve documented competence without the ability to perform IOC. This may have an impact on EGS service delivery of acute and emergency gallbladder surgery including the ability to deal with difficult cases.

ABSTRACTBackgroundCentralising prostate cancer surgical and radiotherapy services, requires some patients to travel longer to access treatment, but its impact on actual treatment utilisation and outcomes is unknown.MethodsUsing national cancer registry records linked to administrative hospital data, we identified all patients with high risk and locally advanced prostate cancer diagnosed between 1 April 2019 and 31 March 2020 in the English National Health Service (n = 15,971). Estimated travel times from the patient residential areas to the nearest hospital providing surgery or radiotherapy were estimated for journeys by car and by public transport. Multivariable logistic regression was used to model relationships between travel time and receipt of care with adjustment for patient characteristics.Results10,693 (67%) men received radical surgery or radiotherapy (RT) within 12 months of diagnosis. Average travel time to the nearest hospital providing prostatectomy or RT was 23.2 min by private car and 58.2 min by public transport. We found no association between travel time, either by car or public transport and the likelihood of receiving curative treatment. Patients living in the most socially deprived areas, those aged over 70, those with two or more comorbidities, and those of black ethnic origin, were less likely to receive curative treatment (p& =& 0.001 for all associations).ConclusionsThe current configuration of national prostate cancer services is not associated with the likelihood of receiving curative treatment. Further increases in capacity will unlikely improve utilisation rates beyond addressing sociodemographic barriers.

The British Association of Oral and Maxillofacial Surgeons (BAOMS) Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) reconstructive audit aims to provide surgical teams with risk adjusted comparative performance data. The goal is to enable surgeons to optimise surgical pathways. Risk adjustment requires that data on appropriate predictive variables are collected. This study looked at variables predicting major complications and flap failure in a single institution with the aim of determining whether the QOMS dataset adequately captures the appropriate data points. A prospective database of head and neck flap procedures and associated postoperative complications has been maintained in the maxillofacial surgery department since August 2009 up to August 2022 (n=1327). A total of 25 putative risk variables were extracted from the health records for each patient. The outcomes of interest were total flap failure and major complications. Independent predictors of flap failure were recipient site (sinonasal/anterior skull base), previous major surgery, previous major surgery and radiotherapy, and flap selection. For major complications ACE-27 comorbidity score, flap type, use of tracheostomy, elevated preoperative plasma C-reactive protein (CRP) and flap selection were independently predictive. Apart from preoperative activated innate immunity all relevant risk stratification variables identified in this study form part of the QOMS dataset. QOMS is therefore likely to adequately risk stratify patients based upon currently collected variables.

AbstractMesenchymal stem cell‐derived extracellular vesicles (MSC‐EVs) have shown promising immunomodulatory capabilities for a variety of clinical conditions. However, the potential regulatory mechanisms of MSC‐EVs in allergic rhinitis (AR) remain unexplored. The present study was designed to investigate the immunomodulatory effect of MSC‐EVs in patients with AR. Peripheral blood mononuclear cells (PBMCs) were isolated from AR patients. The number of peripheral CD4+Foxp3+IL‐17+, CD4+Foxp3+IL‐17− and CD4+Foxp3−IL‐17+ T cells in healthy controls and AR patients were evaluated using flow cytometry. Therapeutic effect of MSC‐EVs was determined by detecting IFN‐γ, IL‐4, IL‐17 and IL‐10 cytokines in supernatant by ELISA and flow cytometry. The mean fluorescence intensity (MFI) was calculated in PBMCs for IL‐10, IL‐17 and TGF‐β on T cells after MSC‐EVs treatment. Bioinformatic analysis of microRNA was performed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. CD4+Foxp3+IL‐17+ T cells expression in PBMCs was higher in the AR group and the balance of Treg/Th17 was tilted towards Th17 cells. Supernatant from AR patients revealed that MSC‐EVs treatment upregulated IL‐10 and IFN‐γ, and downregulated IL‐4 and IL‐17. EVs treatment effectively re‐established Th1(CD4+IFN‐γ+cells)/Th2(CD4+IL‐4+cells) balance, reduced CD4+IL‐17+ and increased CD4+IL‐10+ and CD4+TGF‐β+ cells. The MFI of IL‐10 and TGF‐β in CD4+CD25+CD127− T cells were higher, whereas lower levels of IL‐17 were observed. Bioinformatic analysis revealed that the TGF‐β, Wnt signalling pathways and STAT5 transcription factor might mechanistically support the immunomodulatory effect of MSC‐EVs. This study presents the immunomodulatory effect of MSC‐EVs in PBMCs from AR patients. The results provide a new therapeutic strategy for AR.

AbstractAimLocally advanced and recurrent colorectal cancer represents a complex clinical entity, which requires multidisciplinary decision‐making and management. The aim of this work is to understand the provision of clinical services in this cohort of patients across Great Britain and Ireland (GB&I) as a key essential step to help facilitate future service development and improvement.MethodA cross‐sectional, organizational survey was sent to all colorectal cancer multidisciplinary teams (MDTs) across GB&I. It consisted of 12 key questions addressing the provision of specialist services and advanced surgical techniques. Results are reported in line with the CHERRIES guideline.ResultsOne hundred and seventy‐five MDTs across GB&I participated, with 142 English, 13 Welsh, 14 Scottish, 3 Northern Irish and 3 Irish MDTs. The overall response rate was 93.5% (175/187). Ninety (51.4%) hospital sites reported having a specialist dedicated or subsection MDT. Specialist advanced nursing support was available in 46 (26.2%) hospitals, with a dedicated advanced colorectal cancer outpatient clinic available in 31 (17.7%) hospitals. One hundred and thirteen MDTs (64.5%) offered surgery for advanced colonic cancer, 82 (46.8%) for recurrent colonic cancer, 58 (33.1%) for advanced rectal cancer and 39 (22.2%) for recurrent rectal cancer. A variable number of MDTs offered specialist surgical techniques, including distal sacrectomy [33 (18.9%)], high sacrectomy [16 (9.1%)], complex vascular resection ± reconstruction [33 (18.9%)] and extended lymphadenectomy (pelvic sidewall or para‐aortic) [44 (25.1%)].ConclusionThe IMPACT organizational survey highlights the current variation in the delivery and provision of clinical services for patients with advanced and recurrent colorectal cancer across Great Britain and Ireland.
