Abstract:Background: Gastric cancer (GC) is the 5th most common malignancy and remains one of the major causes of worldwide cancer-related deaths. COVID-19 pandemic has had a significant impact on the provision of cancer care. This study aims to overview the global standpoint of gastric cancer patients (GCP) during the first year of pandemic (PY1).
Material(s) and Method(s): The Upper Gastrointestinal Surgeons (TUGS), within its Global Level of Harm Project, designed an online cross-sectional survey to assess how GCP's management changed during PY1. The questionnaire included 33 questions about expertise, kind of health system, hospital organization and screening policies, personal protective equipment (PPE), change in patient's characteristics, preoperative, operative and postoperative management of GCP.Result(s): There were 209 answers from 178 centres (50 countries) around the world. Results of the survey showed: most hospitals (88,2%) had restricted areas for the management of COVID-19 patients; 53,6% of participants were redeployed; most frequent COVID-19 screening methods were PCR (78,8%) and chest CTscan (25,6%), and 55,9% thought there was a lack of PPE. Preoperative management: 43,2% decrease in the number of multidisciplinary teams (MDT) meetings; 28,4% increase in the number of cT2 or higher GCP; 34,7% increase in metastatic (M1) GCP; 26,8% increase in GCP receiving definitive palliative treatment; 23,7% increase in the number of frail patients; 50% increase in waiting list time (WLT); and 41,6% faced problems in the provision of oncological treatment. Operative management: 54,5% decrease in elective gastrectomies; 29,1% increase in the number of urgent/semi-urgent gastrectomies; 37% decrease in the number of minimally invasive gastrectomies (MIG); and 18,5% increase in the number of surgeries with palliative intent. Postoperative management: 16,5% increase in the overall complication rate (OCR); 12,6% increase in the number of Clavien-Dindo 3 or higher complications; 8% increase in the leak rate; increase in pulmonary infections (26,8%) and bowel obstruction (2,4%); 44,5% development of postoperative COVID-19 infection; 15,4% increase in 30-days mortality rate; 23,1% mortality due to COVID-19 infection; 17,6% increase in the need for adjuvant treatment. Most patients were postoperatively assessed either through a face to face consultation or a combination of face to face and remote consultation.
Conclusion(s): COVID-19 pandemic has affected GC management by decreased frequency of MDT's, higher clinical-stage migration and fuelled frailty. The pandemic increased WLT, the number of urgent and palliative surgeries, OCR, Clavien-Dindo 3 or higher complications, leak rate, and pulmonary infections. There was a noticeable high rate of postoperative COVID-19 infection and associated mortality. Further multicentric studies are warranted to affirm these findings.

Abstract:The genetic make-up of an individual contributes to the susceptibility and response to viral infection. Although environmental, clinical and social factors have a role in the chance of exposure to SARS-CoV-2 and the severity of COVID-19<sup>1,2</sup>, host genetics may also be important. Identifying host-specific genetic factors may reveal biological mechanisms of therapeutic relevance and clarify causal relationships of modifiable environmental risk factors for SARS-CoV-2 infection and outcomes. We formed a global network of researchers to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity. Here we describe the results of three genome-wide association meta-analyses that consist of up to 49,562 patients with COVID-19 from 46 studies across 19 countries. We report 13 genome-wide significant loci that are associated with SARS-CoV-2 infection or severe manifestations of COVID-19. Several of these loci correspond to previously documented associations to lung or autoimmune and inflammatory diseases<sup>3-7</sup>. They also represent potentially actionable mechanisms in response to infection. Mendelian randomization analyses support a causal role for smoking and body-mass index for severe COVID-19 although not for type II diabetes. The identification of novel host genetic factors associated with COVID-19 was made possible by the community of human genetics researchers coming together to prioritize the sharing of data, results, resources and analytical frameworks. This working model of international collaboration underscores what is possible for future genetic discoveries in emerging pandemics, or indeed for any complex human disease.

Abstract:Background: Combined Lung Ultrasound (LUS) and Focused UltraSound for Intensive Care heart (FUSIC Heart – formerly Focused Intensive Care Echocardiography, FICE) can aid diagnosis, risk stratification and management in COVID-19. However, data on its application and results are limited to small studies in varying countries and hospitals. This United Kingdom (UK) national service evaluation study assessed how combined LUS and FUSIC Heart were used in COVID-19 Intensive Care Unit (ICU) patients during the first wave of the pandemic. Method(s): Twelve trusts across the UK registered for this prospective study. LUS and FUSIC Heart data were obtained, using a standardised data set including scoring of abnormalities, between 1st February 2020 to 30th July 2020. The scans were performed by intensivists with FUSIC Lung and Heart competency as a minimum standard. Data was anonymised locally prior to transfer to a central database. Result(s): 372 studies were performed on 265 patients. There was a small but significant relationship between LUS score >8 and 30-day mortality (OR 1.8). Progression of score was associated with an increase in 30-day mortality (OR 1.2). 30-day mortality was increased in patients with right ventricular (RV) dysfunction (49.4% vs 29.2%). Severity of LUS score correlated with RV dysfunction (p < 0.05). Change in management occurred in 65% of patients following a combined scan. Conclusion(s): In COVID-19 patients, there is an association between lung ultrasound score severity, RV dysfunction and mortality identifiable by combined LUS and FUSIC Heart. The use of 12-point LUS scanning resulted in similar risk score to 6-point imaging in the majority of cases. Our findings suggest that serial combined LUS and FUSIC Heart on COVID-19 ICU patients may aid in clinical decision making and prognostication.

Abstract:
Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231 patients (116 countries), 3127 patients (2.2%) had a pre-operative SARS-CoV-2 diagnosis. Adjusted 30-day mortality in patients without SARS-CoV-2 infection was 1.5% (95%CI 1.4–1.5). In patients with a pre-operative SARS-CoV-2 diagnosis, mortality was increased in patients having surgery within 0–2 weeks, 3–4 weeks and 5–6 weeks of the diagnosis (odds ratio (95%CI) 4.1 (3.3–4.8), 3.9 (2.6–5.1) and 3.6 (2.0–5.2), respectively). Surgery performed ≥ 7 weeks after SARS-CoV-2 diagnosis was associated with a similar mortality risk to baseline (odds ratio (95%CI) 1.5 (0.9–2.1)). After a ≥ 7 week delay in undertaking surgery following SARS-CoV-2 infection, patients with ongoing symptoms had a higher mortality than patients whose symptoms had resolved or who had been asymptomatic (6.0% (95%CI 3.2–8.7) vs. 2.4% (95%CI 1.4–3.4) vs. 1.3% (95%CI 0.6–2.0), respectively). Where possible, surgery should be delayed for at least 7 weeks following SARS-CoV-2 infection. Patients with ongoing symptoms ≥ 7 weeks from diagnosis may benefit from further delay.

British Journal of Surgery. 2021 Sep 27;108(9):1056-1063

Abstract:
Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling.
Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18–49, 50–69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty.
Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year.
Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.

Abstract:
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.

Abstract:
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 days of surgery. SARS-CoV-2 diagnosis was defined as peri-operative (7 days before to 30 days after surgery); recent (1–6 weeks before surgery); previous (≥7 weeks before surgery); or none. Information on prophylaxis regimens or pre-operative anti-coagulation for baseline comorbidities was not available. Postoperative venous thromboembolism rate was 0.5% (666/123,591) in patients without SARS-CoV-2; 2.2% (50/2317) in patients with peri-operative SARS-CoV-2; 1.6% (15/953) in patients with recent SARS-CoV-2; and 1.0% (11/1148) in patients with previous SARS-CoV-2. After adjustment for confounding factors, patients with peri-operative (adjusted odds ratio 1.5 (95%CI 1.1–2.0)) and recent SARS-CoV-2 (1.9 (95%CI 1.2–3.3)) remained at higher risk of venous thromboembolism, with a borderline finding in previous SARS-CoV-2 (1.7 (95%CI 0.9–3.0)). Overall, venous thromboembolism was independently associated with 30-day mortality (5.4 (95%CI 4.3–6.7)). In patients with SARS-CoV-2, mortality without venous thromboembolism was 7.4% (319/4342) and with venous thromboembolism was 40.8% (31/76). Patients undergoing surgery with peri-operative or recent SARS-CoV-2 appear to be at increased risk of postoperative venous thromboembolism compared with patients with no history of SARS-CoV-2 infection. Optimal venous thromboembolism prophylaxis and treatment are unknown in this cohort of patients, and these data should be interpreted accordingly.

Abstract:
The coronavirus pandemic (COVID-19) has had unprecedented effects on healthcare delivery. A 34-question online survey was sent to obstetrics and gynaecology trainees within the West Midlands to assess the impact of the pandemic on training, working practices and well-being. 101 responses were received from obstetrics and gynaecology trainees. Trainees reported a significant reduction in both elective and emergency surgeries as well as outpatient clinics. Over one third of respondents felt additional training time may be required following reduction of clinical opportunities. 44% of trainees felt their workload increased significantly. 55% of trainees felt the pandemic had a significant negative impact on their physical and mental well-being. Obstetrics and gynaecology trainees in the West Midlands have adapted to the challenges of the COVID-19 pandemic despite significant impact on their training, working practices and wellbeing. It is important to tailor training to improve trainees' education and combat lost training time during the pandemic. This should be considered for long-term shaping of the obstetrics and gynaecology training pathway. IMPACT STATEMENT What is already known on this subject? Little research is available about the impact of the COVID-19 pandemic on obstetrics and gynaecology trainees. This is the first study of its kind to assess the effect of the pandemic on obstetrics ang gynaecology trainees in the United Kingdom. What do the results of this study add? The results of this study have shown that obstetrics and gynaecology training has been heavily affected during the COVID-19 pandemic. There have been significant impacts on their training, working patterns and physical and mental wellbeing. What are the implications of these findings for clinical practice and/or further research? These findings can be used to mould the obstetrics and gynaecology training pathway based on the feedback given by the trainees during the pandemic. The survey questions can also be utilised as a framework for similar research projects across the United Kingdom Deaneries, among other specialties and around the world.

Abstract:
Background: Nosocomial spread of Coronavirus has been an issue for hospitals across the UK, with a recent report by Public Health England (PHE) and the London School of Hygiene and Tropical Medicine (LSHTM) stating that the effective reproduction rate of SARS-CoV-2 in hospitals has been projected to have been as high as 14 during the first wave of the pandemic [1]. In order to stifle this spread hospital Infection and Prevention Control (IPC) set out regular guidelines concerning when patients should be tested for COVID-19.
Aims and objectives: We attempted to assess how well our trust followed the IPC guidance for testing patients for COVID-19, specifically with regard to swab timing following admission to hospital.
Methods: We analysed all admissions to the hospital during the week of 1st October 2020 to the 7th October 2020. We looked at how many patients were appropriately swabbed on day 1, and day 5, as was required according to IPC guidance at the time.
Results: We found that of the 266 patients admitted in the said week, 4 patients (1.5%) had a swab greater than 24 hours after admission, and 17 (6.39%) patients did not have a PCR swab at all. 148 patients stayed in hospital 5 days or greater, with 19 patients (17.27%) receiving their second swab correctly on day 5 of admission and 91 patients (82.73%) either not having their swab on the correct day or not having a follow up swab at all.
Conclusion: While testing on entry was generally done in a timely manner, follow-up swabs are not performed according to the guidelines set out by IPC, and therefore not following evidence-based practice.

Author(s):*Howard E.; *Arshad S.; *Kabariti R.; *Roach R.

Citation:British Journal of Surgery; Sep 2021; vol. 108, Supplement 6

Abstract:Aim: To assess the effect of lockdown and the following summer period on paediatric trauma patients who required an operative intervention in a district general hospital. Method(s): A single centre retrospective audit was performed on all paediatric patients <16 years requiring an operative intervention. Two study periods were assessed-pre-COVID (22/03/2019-30/09/2019) and during the COVID-19 pandemic and subsequent summer period (26/03/ 2020-26/09/2020). Data were collected on patient demographics, type of injury sustained, and intervention performed. Result(s): During the COVID-19 pandemic 119 operations were performed, compared to 238 operations performed before the pandemic. Distal radius fractures were the most common injury both during and before the pandemic. However, during the pandemic there was a higher incidence of both hand injuries and lower limb lacerations. The most common type of operation both before and during the pandemic was manipulation under anaesthetic, but there was an increased incidence of washouts performed during the pandemic. Conclusion(s): Despite extensive restructuring of services due to COVID-19, 119 operations were performed during the pandemic. However, this is 119 fewer operations than the same period of the previous year. The reduced rate of operations could be a consequence of increased parental supervision, and less outdoor activity during the pandemic period, but further research is necessary.
