Two randomized, open-label, noninferiority phase 3 trials compared the prolyl hydroxylase inhibitor vadadustat with darbepoetin alfa in patients with incident or prevalent chronic kidney disease who were undergoing dialysis. Vadadustat was noninferior to darbepoetin alfa with respect to cardiovascular safety and correction and maintenance of hemoglobin concentrations.

Postoperative ileus (POI) has long been a challenging clinical problem for both patients and healthcare physicians alike. Although a standardized definition does not exist, it generally includes symptoms of intolerance to diet, lack of passing stool, abdominal distension, or flatus. Not only does prolonged POI increase patient discomfort and morbidity, but it is possibly the single most important factor that results in prolongation of the length of hospital stay with a significant deleterious effect on healthcare costs in surgical patients. Determining the exact pathogenesis of POI is difficult to achieve; however, it can be conceptually divided into patient-related and operative factors, which can further be broadly classified as neurogenic, inflammatory, hormonal, and pharmacological mechanisms. Different strategies have been introduced aimed at improving the quality of perioperative care by reducing perioperative morbidity and length of stay, which include Enhanced Recovery After Surgery (ERAS) protocols, minimally invasive surgical approaches, and the use of specific pharmaceutical therapies. Recent studies have shown that the ERAS pathway and laparoscopic approach are generally effective in reducing patient morbidity with early return of gut function. Out of many studies on pharmacological agents over the recent years, alvimopan has shown the most promising results. However, due to its potential complications and cost, its clinical use is limited. Therefore, this article aimed to review the pathophysiology of POI and explore recent advances in treatment modalities and prevention of postoperative ileus.

Significant mitral regurgitation (MR) constitutes an important co-existing valvular heart disease burden in the setting of aortic valve stenosis. There are conflicting reports on the impact of significant MR on outcomes after transcatheter aortic valve implantation (TAVI). We evaluated the impact of MR on outcomes after TAVI by performing a meta-analysis of 8 studies involving 8,927 patients reporting TAVI outcomes based on the presence or absence of moderate-severe MR. Risk ratios (RRs) were calculated using the inverse variance random-effects model. None-mild MR was present in 77.8% and moderate-severe MR in 22.2% of the patients. The presence of moderate-severe MR at baseline was associated with increased mortality at 30 days (RR 1.35, 95% confidence interval [CI] 1.14 to 1.59, p = 0.003) and 1 year (RR 1.24, 95% CI 1.13 to 1.37, p <0.0001). The increased mortality associated with moderate-severe MR was not influenced by the cause of MR (functional or degenerative MR; RR 0.90, 95% CI 0.62 to 1.30, p = 0.56). The severity of MR improved in 61 ± 6.0% of patients after TAVI. Moderate-severe residual MR, compared with none-mild residual MR after TAVI, was associated with significantly increased 1-year mortality (RR 1.48, 95% CI 1.31 to 1.68, p <0.00001). In conclusion, baseline moderate-severe MR and significant residual MR after TAVI are associated with an increase in mortality after TAVI and represent an important group to target with medical or transcatheter therapies in the future.

Restorative proctocolectomy with ileal pouch–anal anastomosis (IPAA) has become standard surgical treatment of choice in patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP) in which the medical management fails. Despite the wide use of laparoscopic method, the enhanced and innovative features that come with the robotic platform, such as endo-wrist technology, 3D visualization, surgeon-controlled camera and motion scaling, make it an appealing choice. This study aims to investigate the feasibility and safety of robotic approach for proctectomy or proctocolectomy with IPAA as compared to conventional laparoscopic approach. A systematic review was completed for studies done between 2010 and 2022 comparing the robotic approach with the laparoscopic approach. Nine studies were found to be feasible to be included in this review. In terms of the outcomes, although the mean operating time was slightly higher than the laparoscopic approach, the other outcomes, such as mean blood loss, return of the bowel movement, mean hospital stay, and conversion to open, were found to be significantly lower in the robotic approach as compared to both laparoscopic and conventional open techniques. Despite the overall increased rate of complications combined from all the studies, the rate of significant complications such as anastomotic leaks requiring readmission and return to theater was also found to be substantially less. This study concludes that although robotic approach is in its initial stages for pelvic surgeries, it can be safely employed due to improved dexterity and visibility.

Background Ectopic pregnancy (EP) is a significant cause of maternal morbidity and mortality. Accurate and timely diagnosis is crucial, particularly in women of reproductive age presenting with acute abdominal pain. This audit aimed to assess the completeness and accuracy of gynecological history documentation, including pregnancy status, in female patients admitted for emergency surgery due to abdominal pain. Methods A retrospective audit was conducted within a single NHS Trust, analyzing the surgical assessment documents of 50 female patients aged 12-50 years admitted for emergency surgery. Data collected included documentation of pregnancy status, gynecological history, last menstrual period, sexual activity, and contraceptive use. A subsequent audit cycle assessed the impact of an educational intervention on documentation practices. Results Initial findings revealed significant deficiencies in the documentation of key gynecological parameters. Pregnancy status was documented in only 14% of cases, and contraceptive use in 20%. A substantial proportion of cases lacked documentation of gynecological history 50% and sexual history 56%. An educational intervention resulted in a significant improvement in the documentation of sexual history, contraceptive use, and pregnancy status. Conclusion This audit revealed significant deficiencies in the initial gynecological assessment of female patients with acute abdominal pain, particularly regarding the documentation of pregnancy status, menstrual history, and contraceptive use. The study highlights the need for improved clinical practices, including enhanced medical education, standardized assessment protocols, and electronic documentation of pregnancy status. Continued research is crucial to address these deficiencies and optimize patient care within the NHS.

The National Institute for Health and Care Excellence (NICE) 2016 guidelines (CG95) recommend patients with new stable chest pain be investigated with computed tomography coronary angiography (CTCA). An updated guideline (MTG32) recommended using CT fractional flow reserve (CTFFR) as a gatekeeper to invasive coronary angiography (ICA) for patients with coronary stenosis on CTCA. Subsequently, NHS England negotiated a UK-wide contract with HeartFlow, the provider of CTFFR. We describe our experience with CTFFR and consider the impact of the recent ISCHEMIA trial on these guidelines. We prospectively collected ICA and revascularisation data on all patients undergoing CTFFR from January 2019 to March 2020. One-hundred and twenty-five of 140 patients completed CTFFR analysis. Eighty-one patients had CTCA stenosis >50%. Thirty-six had positive CTFFR; 29 underwent ICA with 22 (75.9%) revascularised. Forty-five had negative CTFFR; 14 underwent ICA and four (28.6%) were revascularised. The average cost of investigation per patient (PP) was £971.95. Had these patients undergone ICA directly with no functional test after CTCA, the average cost would be £932.51 PP. Our revascularisation rates suggest that CTFFR can potentially be a gatekeeper to ICA but does not necessarily yield cost savings.

IntroductionAcute pancreatitis (AP), characterized by the inflammation of the pancreas, is a common acute surgical condition accounting for approximately 3% of all surgical admissions with abdominal pain and has an incidence of approximately 56 cases per 100,000 population every year. The General Medical Council (GMC), National Institute for Health and Care Excellence (NICE), and Royal College of Nursing best practice guidelines recommend that such patients and their family members should be provided with both verbal and written information about acute pancreatitis and its management in a way that they can understand. The aim of this audit cycle was to find out the compliance with information provided to patients with acute pancreatitis as per the GMC good medical practice and NICE guidelines and assess their satisfaction.MethodA closed-loop audit consisting of two cycles was carried out. Thirty patients who were admitted to the department of general surgery with acute pancreatitis were provided with a questionnaire containing 11 questions asking about the information provided to them about their condition by healthcare professionals; then, interventions were carried out in the form of developing patient information leaflets (PILs) and encouraging healthcare professionals to distribute them and provide information to the patients and their family members.ResultsOverall, improvements were seen in all aspects of the information being provided to patients, and particularly, more than 100% improvement was seen in patient satisfaction related to the information provided to them in the second cycle after the implementation of interventions.ConclusionsThis study concludes that patients should be given all the information they require in accordance with their right to information, in line with GMC best practice, NICE, and Royal College of Nursing best practice guidelines. A very effective way to improve the health outcomes and satisfaction of patients is to give them access to a patient information leaflet, which can allow patients to consider their options and understand what can happen during treatment, especially when doctors have limited time to carry out detailed discussions with the patient.

Introduction Acute cholecystitis (AC), inflammation of the gall bladder, is one of the most common emergency surgical presentations. In the UK, approximately 15% of the population is estimated to have gallstones, and approximately 20% of them can develop AC. Laparoscopic cholecystectomy (LC) is considered the definitive management of AC. However, cholecystectomy carries a very high risk of morbidity and mortality in high-risk frail patients with multiple comorbidities who are deemed unfit for surgery. Percutaneous cholecystostomy (PC), both image-guided and laparoscopic, is generally acknowledged as an interim treatment measure before definitive management, which is the LC. Materials and methods This is a retrospective study from the Royal Albert Edward Infirmary, a district general hospital (DGH) based in Wigan, UK. The medical records of all the patients who were admitted to the surgical department and underwent PC between January 2017 and December 2022 were analyzed. Patients with previous hepato-pancreato-biliary (HPB) malignancy, who underwent open cholecystostomy, or those with abdominal ascites were excluded from the study. Information was collected regarding the age, gender, American Society of Anaesthesiologists (ASA) grades, success rates of both procedures as temporary or definitive management, duration of hospital stay, 30-day and 1-year mortality after the procedure, timing of the procedure, and long-term complications after the procedure, particularly those related to cholecystostomy tube dislodgment or blockage. Results Twenty-seven patients who underwent PC were divided into two groups: group A, consisting of 10 patients who underwent laparoscopic cholecystostomies, and group B, consisting of 17 patients who had ultrasound (US)-guided cholecystostomies. The mean age of the patients in group A was 66.7 as compared to 75.1 in group B. Most of the patients were in ASA groups III (14) and IV (10). About 74% of patients had procedures done during the day and 26% had PC at night time. The mean hospital stay was 13.5 days. About 55% of patients had planned elective LC as a definitive management. Following the treatment, two patients died within 30 days, and eight patients passed away within a year. About 40% of the patients had complications related to the tube dislodgment and blockage. Conclusion This study concludes that PC, using both laparoscopic and US-guided techniques, can serve as an interim as well as a definitive measure, particularly in patients who are at high risk for anesthesia and the procedure itself and have multiple comorbidities.

The role of green finance in driving technological innovation in resource-constrained emerging economies is examined. Despite substantial inflows, many nations struggle to convert funds into green technology advancements, prompting questions about finance-innovation mechanisms. Empirical evidence on heterogeneous impacts of green finance flows on technological innovation is extended, incorporating moderators like institutional quality, energy market dynamics, trade openness, and human capital development. Data from 2004–2023 across 10 BRICS economies (WDI, WGI) are analysed using fixed-effects panel regression and instrumental variable estimation. Renewable Energy Consumption (REC), a proxy for green finance, positively influences technological innovation; a 1% REC increase is associated with a 6.29% innovation rise. Strong institutions amplify this effect while trade openness unexpectedly weakens it. Energy intensity strengthens the linkage, whereas education expenditure negatively moderates it. Prioritization of institutional reforms and alignment of green finance with supportive policies are suggested to maximize technological innovation and advance sustainable development goals (SDGs). Regional variations and feedback loops should be validated to deepen the understanding of technological innovation dynamics.
