Urology never events in the United Kingdom: A retrospective 10-year review.

Objectives: The aim was to assess the prevalence of never events (NEs) specific to urology in the United Kingdom and identify commonly occurring themes. Methods: Data from the National Health Service (NHS) NEs website were obtained and all NEs from 2012 to 2022 were reviewed. Urology-specific NEs were identified and further analysed in their respective categories. Data regarding the total number of surgical procedures performed in the NHS specific to each specialty were obtained via the NHS Hospital Episode Statistics website. Results: There were 3972 NEs recorded over the 10-year period with 95 (2.4%) of these as a result of urology surgery. The most common surgical intervention associated with a urological NE was ureteric stenting, which comprised 45/95 (47.4%) of all analysed NEs. These consisted of wrong site ureteric stent insertion (n = 29), wrong site ureteric stent removal (n = 9), wrong stent type (n = 5) and retained guidewires (n = 2). There were 7.14 million urology surgeries performed in the 10-year period, and prevalence was 0.0013%. Conclusion: NEs are fully preventable serious incidents in the NHS. This is the first study to investigate the prevalence of NEs in urology in the United Kingdom. This study demonstrates that in the last 10 years the prevalence of urology NEs is low at 0.0013%, with ureteric stent procedures accounting for more than half of the NEs. Urologists should be mindful of the potential for wrong site surgery in urologic stenting procedures.

Treatment of Cachexia in Gastric Cancer: Exploring the Use of Anti-Inflammatory Natural Products and Their Derivatives.

(1) Background: Gastric cancer is a significant cause of cancer-related mortality worldwide. Weight loss and malnutrition associated with cancer are linked with increased mortality rates and reduced quality of life. Cancer cachexia, characterised by the loss of skeletal muscle, is associated with approximately 20% of cancer-related deaths and differs from malnutrition in that it cannot be fully reversed by nutritional support alone. It is now recognised that the primary pathophysiological process underlying cancer cachexia is chronic inflammation leading to increased calorie consumption. Current treatments that focus on nutritional supplementation, psychological counselling, appetite stimulation and reducing inflammation are lacking in efficacy. This review focuses on the evidence supporting the potential roles of natural anti-inflammatory products and their derivatives including fatty acids, probiotics, amino acids, curcumin, fucoidan, epigallocatechin-3-gallate, ginger, resveratrol and Boswellia serrata in the management of gastric cancer cachexia. (2) Results: While natural anti-inflammatory products show promise in a number of in vitro and in vivo studies, there are only a small number of human studies available. Where present, the evidence base is heterogeneous, with varying study methodologies and outcomes. (3) Conclusions: Natural anti-inflammatory products represent a potential adjunctive therapy for gastric cancer cachexia. Further research, particularly well-designed clinical trials, is needed to elucidate their optimal role, dosing and safety profiles in the management of gastric cancer cachexia.

Oncological outcomes of patients with oligometastatic oesophagogastric cancer.

Oligometastatic oesophagogastric cancer was recently defined by consensus as the presence of no more than two metastases and an 18-week period of oncological stability during chemotherapy. The number of patients who fit this criterion and whether their oncological outcome differs from those with multi-metastatic disease is unknown. We analysed a database of 497 patients from 2017 to 2021 with metastatic oesophageal cancer. In total, 36 (7.2%) had oligometastatic disease and significantly improved median overall survival (mOS) versus multi-metastatic disease. In synchronous OMD, mOS was 26.8 months versus 7.3 months and in metachronous OMD, 38.6 months versus 6.1 months (both p < 0.0001). A subset of oligometastatic patients who underwent surgical management of their oligometastases after primary tumour resection demonstrated significantly increased mOS compared with systemic treatment alone (60 months versus 24.4 months; p < 0.038). Oligometastatic oesophagogastric cancer is associated with improved oncological outcome when compared to multi-metastatic disease. Further work is needed to identify patients who will benefit from aggressive treatment of metastatic oesophagogastric cancer.

Long-Term Follow-up of Complex Calcaneal Osteomyelitis Treated With Modified Gaenslen Approach.

Background: The treatment of chronic calcaneal osteomyelitis is a challenging and increasing problem because of the high prevalence of diabetes mellitus and operative fixation of heel fractures. In 1931, Gaenslen reported treatment of hematogenous calcaneal osteomyelitis by surgical excision through a midline, sagittal plantar incision. We have refined this approach to allow successful healing and early mobilization in a modern series of complex patients with hematogenous, diabetic, and postsurgical osteomyelitis. Methods: Twenty-eight patients (mean age 54.6 years, range 20-94) with Cierny-Mader stage IIIB chronic calcaneal osteomyelitis were treated with sagittal incision and calcaneal osteotomy, excision of infected bone, and wound closure. All patients received antibiotics for at least 6 weeks, and bone defects were filled with an antibiotic carrier in 20 patients. Patients were followed for a mean of 31 months (SD 25.4). Primary outcome measures were recurrence of calcaneal osteomyelitis and below-knee amputation. Secondary outcome measures included 30-day postoperative mortality and complications, duration of postoperative inpatient stay, footwear adaptions, mobility, and use of walking aids. Results: All 28 patients had failed previous medical and surgical treatment. Eighteen patients (64%) had significant comorbidities. The commonest causes of infection were diabetes ± ulceration (11 patients), fracture-related infection (4 patients), pressure ulceration, hematogenous spread, and penetrating soft tissue trauma. The overall recurrence rate of calcaneal osteomyelitis was 18% (5 patients) over the follow-up period, of which 2 patients (7%) required a below-knee amputation. Eighteen patients (64%) had a foot that comfortably fitted into a normal shoe with a custom insole. A further 6 patients (21%) required a custom-made shoe, and only 3 patients required a custom-made boot. Conclusion: Our results show that a repurposed Gaenslen calcanectomy is simple, safe, and effective in treating this difficult condition in a patient group with significant local and systemic comorbidities. Level of Evidence: Level III, case series.

Patient Outcomes Related to In-Hospital Delays in Appendicectomy for Appendicitis: A Retrospective Study.

Background and objective In many hospitals, the availability of operating theatres and access to senior surgical and anaesthetic support diminish during night hours. Therefore, urgent surgery is sometimes postponed until the following morning rather than performed overnight, if it is judged to be safe. In this study, we aimed to determine if a delay in laparoscopic appendicectomy in cases of acute appendicitis of over 12 hours, analogous to an overnight delay, correlated with worse patient outcomes. Our primary outcome was delayed discharge from the hospital. Our secondary outcomes were appendicitis severity, conversions, and postoperative complications. Methods We undertook a retrospective review of the medical records of patients who underwent laparoscopic appendicectomy for appendicitis at a UK district general hospital between 01/01/2018 and 30/08/2019. For each patient, clinical and demographic information, and time of hospital admission, surgery, and discharge were collected. Delayed discharge was defined as "time to discharge" >24 hours after surgery. Results A total of 446 patients were included in the study. In 137 patients (30.7%), "time to surgery" was under 12 hours; in 309 patients (69.3%) "time to surgery" was over 12 hours. Of note, 319 patients (71.5%) had a delayed discharge; 303 patients (67.9%) had complicated appendicitis, and 143 patients had severe appendicitis (32.1%). No statistically significant association between "time to surgery" and delayed discharge, appendicitis severity, conversion, or 30-day re-presentations was observed. Conclusion Time from admission to the start of appendicectomy did not affect patient outcomes. Short in-hospital delays in appendicectomy, such as an overnight delay, may be safe in certain patients and should be determined based on clinical judgement.

A local experience of non-operative management for an appendicitis cohort during COVID-19.

BACKGROUND: During the first United Kingdom COVID-19 wave, the Royal Colleges of Surgeons initially recommended conservative management with antibiotics instead of surgery for appendicitis. This study compared local outcomes of appendicitis during this period with a pre-COVID-19 cohort. METHODS: An observational study was conducted in a district general hospital. All episodes of appendicitis were prospectively studied from 25th March 2020 until 26th May 2020 and compared with a retrospective pre-COVID cohort from 27th November 2019 until 29th January 2020. Primary outcome was 30-day treatment failure of simple appendicitis for conservatively managed cases during COVID-19 compared to surgically managed cases pre-pandemic. Treatment failure was defined as any unplanned radiological or surgical intervention. RESULTS: Over nine weeks, there were 39 cases of appendicitis during COVID-19 and 50 cases pre-COVID-19. Twenty-six and 50 cases underwent appendicectomy during and pre-COVID-19 respectively. There was no difference in 30-day postoperative complication rates and nor were there any peri-operative COVID-19 infections.Twelve cases of simple appendicitis underwent conservative management during COVID-19 and were compared with 23 operatively managed simple cases pre-pandemic. There was a higher failure rate in the conservative versus operative group (33.3 vs 0% OR = 24.88, 95% CI 1.21 to 512.9, p=0.0095). Length of stay was similar (1.5 vs 2.0 p=0.576). DISCUSSION: Locally, conservative management was more likely to fail than initial appendicectomy. We suggest that surgery should remain first line for appendicitis, with conservative management reserved for those with suspected or proven COVID-19 infection.

Effectiveness of a multi-session combined near-peer and faculty-led surgical skills course on self-perceived ability to perform basic surgical skills.

BACKGROUND: Newly qualified UK doctors report feeling unprepared to perform basic practical procedures. The Royal College of Surgeons of England (RCSEng) responded to this concern by developing a national surgical curriculum, however, a national survey of UK medical schools identified that surgical skills teaching is inconsistent throughout the UK.Peer assisted teaching sessions are delivered by senior students to junior peers and have been demonstrated to be effective in a number of settings. We aimed to develop a peer-led surgical skills course for medical students and assess its efficacy in teaching surgical skills. METHODS: Combined near-peer and faculty-led teaching sessions were delivered to medical students (N = 14). We assessed for confidence in these skills using pre- and post-course Likert scale questionnaires to determine self-perceived benefit. RESULTS: Overall, student confidence in all skills improved by +1.254 (p < 0.0001). Individually, confidence in every skill increased significantly, including continuous suturing, knot tying and excision and closure, which improved by +1.45 (p < 0.001), +1.22 (p < 0.05) and +1.59 (p < 0.0001), respectively. DISCUSSION: This study demonstrates that teaching provided through near-peer faculty improves medical student confidence in basic surgical skills. A similar course design could be implemented in other UK medical schools to improve the surgical skills of newly graduated doctors.

Novel coronavirus (COVID-19) infection: What a doctor on the frontline needs to know.

Coronavirus disease 2019 (COVID-19) is a zoonotic respiratory infection originating from Wuhan, China. Rapidly spreading from Wuhan to all inhabited continents of the world, the World Health Organisation declared COVID-19 a pandemic on March 11, 2019. Infected patients present with fever and cough; radiological features include bilateral infiltrates on chest x-ray and computed tomography scanning. Management is supportive with oxygen supplementation, broad-spectrum antibiotics as well as careful fluid balancing. A number of drugs, both new and old, are currently in clinical trials and being used on an experimental basis in clinical practice. The COVID-19 pandemic is the greatest worldwide public health crisis of a generation, and has led to seismic political, economic and social changes. This review provides an overview of COVID-19 for junior doctors who find themselves on a new frontline of healthcare.

Production and regulation of interleukin-1 family cytokines at the materno-fetal interface.

IL-1 family members regulate innate immune responses, are produced by gestation-associated tissues, and have a role in healthy and adverse pregnancy outcomes. To better understand their role at the materno-fetal interface we used a human tissue explant model to map lipopolysaccharide (LPS)-stimulated production of IL-1α, IL-1ß, IL-18, IL-33, IL-1Ra, IL-18BPa, ST2 and IL-1RAcP by placenta, choriodecidua and amnion. Caspase-dependent processing of IL-1α, IL-1ß, IL-18, and IL-33 and the ability of IL-1α, IL-1ß, IL-18, and IL-33 to regulate the production of IL-1RA, IL-18BPa, ST2 and IL-1RAcP was also determined. LPS acted as a potent inducer of IL-1 family member expression especially in the placenta and choriodecidua with the response by the amnion restricted to IL-1ß. Caspases-1, 4 and 8 contributed to LPS-stimulated production of IL-1ß and IL-18, whereas calpain was required for IL-1α production. Exogenous administration of IL-1α, IL-1ß, IL-18, and IL-33 lead to differential expression of IL-1Ra, IL-18BPa, ST2 and IL-1RAcP across all tissues examined. Most notable were the counter-regulatory effect of LPS on IL-1ß and IL-1Ra in the amnion and the broad responsiveness of the amnion to IL-1 family cytokines for increased production of immunomodulatory peptides and soluble receptors. The placenta and membranes vary not only in their output of various IL-1 family members but also in their counter-regulatory mechanisms through endogenous inhibitory peptides, processing enzymes and soluble decoy receptors. This interactive network of inflammatory mediators likely contributes to innate defence mechanisms at the materno-fetal interface to limit, in particular, the detrimental effects of microbial invasion.
