The emotional toll of day-of-surgery cancellations on patients - a qualitative study using participant observation and interviews

OBJECTIVES

To explore patients' experiences of day-of-surgery cancellation and the initial days of the extended waiting period.

METHODS

A qualitative explorative design inspired by Ricoeur's phenomenological-hermeneutic approach was used. Participant observation of day-of-surgery cancellations and semi-structured follow-up interviews with patients were conducted. Transcribed data were analysed using a Ricoeur-inspired analysis.

RESULTS

Five themes emerged from the analysis and interpretation, including "an unexpected and shocking message-triggering reactions ranging from crying to unclear thinking", "shattered mental strength-an emotional rollercoaster marked by exhaustion and concerns", "a fragile situation-the need for early, informative and caring management of surgery cancellation", "prolonged waiting-feeling stuck and mentally distressed, caught in limbo with one's disease" and "known and unknown consequences-a butterfly effect".

CONCLUSIONS

Surgery cancellation could be explained as a "butterfly effect" causing known and unknown consequences triggered by the initial shock. Various emotional reactions followed the event and patients' mental strength was shattered. Provision of empathic care and information during cancellation notification was essential. The prolonged waiting period subjected patients to a sense of being stuck in limbo, unable to move forward with their lives. Multiple new practical preparations had to be made, and trust in the healthcare sector might be compromised.

Decoding virulence and resistance in Klebsiella pneumoniae: Pharmacological insights, immunological dynamics, and in silico therapeutic strategies

Klebsiella pneumoniae (K. pneumoniae) has become a serious global health concern due to its rising virulence and antibiotic resistance. As one of the leading members of ESKAPE pathogens, it plays a major role in a wide range of infections that cause pneumonia, urinary tract infections, and bacteremia, especially in immunocompromised and hospitalized patients. The recent increase in multidrug-resistant (MDR) and hypervirulent (hvKP) strains due to the production of extended-spectrum beta-lactamases (ESBLs) and carbapenemases, has greatly limited therapeutic options that highlights the need for novel approaches to combat the pathogen. This review outlines the virulence mechanisms, profiles of antibiotic resistance, and immune evasion strategies in K. pneumoniae. Also, it points out the role of capsular polysaccharides, lipopolysaccharides, and fimbriae in host colonization and immune evasion. Additionally, the review discusses the emerging therapeutic strategies of vaccine development, computational drug discovery, and the use of artificial intelligence (AI). The progress achieved in reverse vaccinology and structural biology enables the identification of new drug and vaccine targets, whereas AI and machine learning (ML) stand out as powerful candidates for high-throughput screening and drug design. However, challenges with antigenic variability, safety, and the need to collaborate globally still exist. This review focuses on the need for interdisciplinary approaches involving molecular biology and immunology with computational sciences to address K. pneumoniae infections and provide appropriate therapies in the era of antibiotic resistance.

Disaster preparedness and kidney health in children

Disasters pose significant risks to vulnerable populations, particularly children with chronic health conditions such as kidney disease. This paper explores the unique challenges faced by children with kidney disease during and after disasters, focusing on disruptions to essential medical services such as dialysis, access to clean water, and maintenance medications. The vulnerability of these children is further amplified in low-resource settings, where disaster preparedness is often lacking. We present strategies for improving disaster preparedness, including early dialysis initiation, patient and family education, and securing reliable access to medical supplies and treatment facilities. Ensuring the resilience of health systems and comprehensive disaster planning are crucial to safeguarding the health of this at-risk population during emergency situations.

Comparative outcomes of laparoscopic and open surgery in inflammatory bowel disease in pediatric and young adult patients: a systematic review and meta-analysis

BACKGROUND

Pediatric inflammatory bowel disease (IBD), encompassing Crohn's disease, ulcerative colitis, and indeterminate colitis, often necessitates surgical intervention in cases of severe or refractory disease. Although biologic therapies have significantly reduced the need for surgery, operative management remains essential for certain patients. The choice between laparoscopic (laparoscopy group [LG]) and open conventional surgery (open group [OG]) continues to be a subject of debate. This meta-analysis aimed to compare the postoperative outcomes of LG and OG in pediatric patients with IBD.

METHODS

We conducted a meta-analysis of observational studies comparing LG and OG outcomes in pediatric patients with IBD. Key outcomes analyzed included major and minor postoperative complications, reoperations, readmissions, operative time, and length of hospital stay.

RESULTS

Seven studies met the inclusion criteria, analyzing 3417 patients, with 1399 (41%) undergoing OG and 2018 (59%) undergoing LG. Our analysis revealed no significant differences in major postoperative complications, reoperation, and readmissions between LG and OG (P = .114, P = .082, and P = .641, respectively). However, LG was associated with shorter hospital stays (6.04 vs 8.35 days; P < .05). Conversions from LG to open surgery amounted to a total of 153 (7.57%). Open surgery had a significantly shorter operative time (173.8 vs 195.5 min; P = .005).

CONCLUSION

Both laparoscopic and open conventional surgeries are safe, effective, and reliable in managing pediatric IBD. Although open surgery offers shorter operative times, laparoscopy reduces hospital stay and minor postoperative complications. The choice of approach depends on the surgeon's experience and patient-specific factors.

Contemporary epidemiologic overview of adult liver trauma management across the United States: Analysis of the American College of Surgeons Trauma Quality Improvement Program database

INTRODUCTION

Multiple definitive and temporizing management techniques have been devised for liver trauma, and we have shifted toward nonoperative management as endovascular capabilities have evolved. Despite management guidelines, no large-scale data on implementation exist. This study characterizes current nationwide liver trauma management.

METHODS

This was an analysis of 2017-2020 American College of Surgeons Trauma Quality Improvement Program. Adult patients with liver trauma were included, with the exclusion of those with severe extra-abdominal injuries (Abbreviated Injury Scale >3). Nonoperative management was defined as no exploratory laparotomy (ex-lap) within 6 hours. Primary outcomes were management strategies employed and failure of nonoperative management (ex-lap after 6 hours), stratified by injury mechanism, American Association for the Surgery of Trauma liver injury grade, and American College of Surgeons trauma center verification level. Secondary outcomes were mortality, survivor-only length of stay, and in-hospital complications. Interfacility transfer patients were subanalyzed.

RESULTS

A total of 96,652 patients with liver trauma were identified, of which 60,199 were included [24% penetrating; 74% blunt]. In total, 60% grade I/II injuries, 21% grade III, 14% grade IV, 5% grade V, and 0.2% grade VI. Mean age 39 ± 17 years, 65% male, 58% White, ISS was 17[12-24], liver-AIS 2[2-4], and lowest systolic blood pressure within 1-hour was 84 ± 31 mm Hg. Mortality was 5%, hospital length of stay was 6 [2-13] days, and intensive care unit length of stay 3 [2-6] days. Both blunt and penetrating liver injuries of all severities were more likely to undergo operative management at higher American College of Surgeons trauma center verification levels. Of 13,672 patients who were transferred, 92% underwent nonoperative management, 1.3% angioembolization, and only 3.4% failed nonoperative management.

CONCLUSION

Liver trauma remains a major public health burden with mortality approaching 66% among severely injured patients, and current management shows significant nationwide variability. Blunt liver trauma is primarily being managed nonoperatively, and angioembolization is assuming a growing role. Very few patients who were transferred to greater levels of care required operative intervention, having implications for resource allocation.

Incomplete neoadjuvant chemo(radio)therapy negatively impacts pathological response and overall survival in locally advanced esophageal cancer

BACKGROUND

Neoadjuvant chemoradiation (nCRT) and resection is one treatment option for esophageal and gastroesophageal junction cancer. In some patients, the full chemotherapy regimen is not completed. We assessed the association between incomplete administration of neoadjuvant chemo(radiation) and pathological response (pCR) and overall survival (OS) in esophageal adenocarcinoma (OAC) and squamous cell carcinoma (OSCC).

METHODS

Patients with OAC and OSCC treated with nCRT and esophagectomy diagnosed in 2015-2022 were identified from the Netherlands Cancer Registry. The association of pCR with any change in the chemotherapy was assessed using multivariable logisitic regressions. Kaplan-Meier method and Cox regression models were used to investigate OS and to adjust for confounding variables.

RESULTS

3340 patients with OAC and 685 patients with OSCC were included. In OAC, in 10 % (n = 323) the chemotherapy was administered incomplete. This was associated with a significantly lower odds for pCR compared to complete chemotherapy (15 % vs 21 %, adjusted OR, 0.69; 95 % CI, 0.30-0.79; p = 0.026). In OSCC this association was not found (adjusted OR, 1.31; 95 % CI, 0.82-2.10; p = 0.267). OAC patients with incomplete chemotherapy had a worse median OS (31.8 months vs 42 months; adjusted HR: 1.26; 95 % CI: 1.08-1.46) compared to patients who received complete chemotherapy. In OSCC this difference in median OS (85.6 months vs 57.2 months; adjusted HR: 1.16; 95 % CI: 0.83-1.60) was not observed.

CONCLUSION

This nationwide study demonstrates that incomplete administration of chemotherapy in the nCRT scheme is associated with worse oncologic outcomes in patients with OAC.

Risk factors and outcomes of Clostridioides difficile infection in patients with colorectal cancer: critical perspective in management

Colorectal cancer (CRC) ranks as the third most prevalent cancer worldwide, causing a serious threat to global health and social burden. Clostridioides difficile infection (CDI) is one of the most important nosocomial infections and has a higher incidence in cancerous population compared with non-cancerous cases. Different risk factors, including gut microbiota dysbiosis, extensive surgery, chemotherapy, prolonged hospitalization, and antimicrobial therapy, compromise host defenses against CDI and contribute to cancer patients' susceptibility to this infection. The emergence of CDI in patients with CRC creates conditions for therapy escalation and prolonged hospitalization, highlighting the need for correct and effective CDI management in these patients. Here, common risk factors associated with CDI in patients with CRC are discussed. In addition, different available techniques for the prevention, detection, and treatment of CDI with the lowest impact on gut microbiota diversity are summarized. This review aims to improve the understanding of the interplay between CDI and CRC and provide new insights into restoring and maintaining gut microbiota balance during CDI management in patients with CRC.

Does pediatric trauma center designation matter for children in shock from gunshot wounds? A Trauma Quality Improvement Program analysis

BACKGROUND

Recent studies have demonstrated improved outcomes for severely injured pediatric trauma patients treated at pediatric trauma centers (PTCs). Nonetheless, specific injury patterns requiring immediate lifesaving intervention may offset the recognized benefits of PTC over adult trauma centers (ATCs). This study aims to compare the clinical outcomes of hypotensive pediatric trauma patients with gunshot wounds (GSWs), based on trauma center type. We hypothesize that outcomes are equivalent for this clinical scenario.

METHODS

The 2013-2021 Trauma Quality Improvement Program data set was used to identify all hypotensive pediatric patients (15 years or younger) with GSWs. Hypotension was defined per Pediatric Advanced Life Support Guidelines. Patients with an Abbreviated Injury Scale score of 6 in any region and transferred patients were excluded. In order to identify the association between PTC verification status and outcomes, Poisson regression models with robust standard errors were used.

RESULTS

A total of 687 patients met the criteria for analysis, and 236 (34%) cases were treated at PTCs. Pediatric trauma center patients were slightly younger (lower quartile, 10 vs. 12 years old; p = 0.037). There was no significant difference in Injury Severity Score or crude mortality rates (68.1% vs. 70.8%, p = 0.524). After adjusting for confounders, Poisson regression showed no reduction in in-hospital mortality, complications, failure to rescue, intensive care unit admission, or mechanical ventilation rates at PTCs compared with ATCs.

CONCLUSION

Gunshot wounds in children pose unique clinical challenges. Majority of cases are cared for at ATCs. Analysis of best available data did not demonstrate a benefit to managing these patients at a PTC. Conversely, ATCs were not superior, despite managing this scenario in both adults and children more often. These findings underscore the importance of ATCs in the care of this particular injury pattern and call attention to the recent pediatric readiness requirements for American College of Surgeons (ACS)-verified trauma centers to treat pediatric firearm injuries at both PTCs and ATC.

The role of inflammatory parameters in predicting acute complicated diverticulitis

AIM

Acute diverticulitis is an inflammatory process associated with pericolonic inflammation involving one or more colonic diverticula and is usually classified as uncomplicated or complicated.

METHOD

This multicenter study retrospectively examined the data of 135 patients who received inpatient treatment for diverticulitis in two tertiary hospitals. Some inflammation scores were calculated with the data obtained from the patients' Complete blood count(CBC) and biochemical laboratory results, and the power of these scores in predicting complicated diverticulitis was examined.

RESULTS

A total of 135 patients (57 men and 78 women) were included in this study. In the ROC analysis performed to evaluate the effectiveness of predicting complications, the CRP/Albumin(CAR) score was found to be significant (AUC: 0.762, p = 0.001). For a cutoff value > 0.25, CAR predicted complications with 73% sensitivity and 76% specificity (AUC: 0.762, p = 0.001).

CONCLUSION

Determining the severity of the disease by differentiating complicated from uncomplicated cases will contribute to reducing hospital stay times and related costs. Our study showed that CAR score can be used as a reliable, inexpensive, and rapid marker for predicting complicated diverticulitis in acute diverticulitis.

Source control in intra-abdominal infections: What you need to know

ABSTRACT

Providing optimal source control (SC) for intra-abdominal sepsis (IAS) is a critically important surgical principle, yet one that remains nebulous in terms of strict definitions and required conduct. The entire concept of SC has evolved in the last decades. Contemporary SC is not only surgical but also embraces minimally invasive percutaneous and medical therapies. We propose that adequate SC has evolved from the mere anatomical control of enteric leakage, cleansing of obvious contaminants and necrosis, to a more comprehensive anatomo-phyiological-biochemical model. While any breaches in the integrity of the gastrointestinal tract should be addressed urgently, SC should ultimately aim to control the generation and propagation of systemic biomediators, bacterial toxins, and toxic catabolites that perpetuate multisystem organ failure and death. Much urgently needs to be learned to understand and hopefully mitigate the dysbiotic influences of IAS on the human microbiome. Finally, the therapy offered should always be individualized, recognizing patient's unique pathophysiology, clinical condition, comorbidities, and predeclared preferences regarding invasive therapies and life-support.

Current status of artificial intelligence colonoscopy on improving adenoma detection rate based on systematic review of multiple metanalysis

BACKGROUND

Colorectal cancer (CRC) can be prevented by screening and early detection. Colonoscopy is used for screening, and adenoma detection rate (ADR) is used as a key quality indicator of sufficient colonoscopy. However, ADR can vary significantly among endoscopists, leading to missed polyps or cancer. Artificial intelligence (AI) has shown promise in improving ADR by assisting in real-time polyp identification or diagnosis. While multiple randomized controlled trials (RCTs) and metanalyses highlight the benefits of AI in increasing detection rates and reducing missed polyps, concerns remain about its real-world applicability, impact on procedure time, and cost-effectiveness.

AIM

To explore the current status of AI assistance colonoscopy in adenoma detection and improving quality of colonoscopy.

METHODS

This systematic review followed PRISMA guidelines, both PubMed and Web of Science databases were used for articles search. Metanalyses and systematic reviews that assessed AI's role during colonoscopy. English article only published between January 2000 and January 2025 were included. Articles related to non-adenoma indications were excluded. Data extraction was independently performed by two researchers for accuracy and consistency.

RESULTS

22 articles met the inclusion criteria, with significant heterogeneity (I² = 28%-91%) observed in multiple studies. The number of studies per metanalysis ranged from 5 to 33, with higher heterogeneity in analyses involving more than 18 RCTs. AI demonstrated improvement in ADR, with an approximate 20% increase across multiple studies. However, its effectiveness in detecting flat or serrated adenomas remains unproven. Endoscopists with low ADR benefit more from AI-colonoscopies, while expert endoscopists outperformed AI in ADR, adenoma miss rate, and the identification of advanced lesions. No significant change in withdrawal time was observed when comparing AI-assisted colonoscopy to conventional endoscopy.

CONCLUSION

While AI-assisted colonoscopy has been shown to improve procedural quality, particularly for junior endoscopists and those with lower ADR, its performance decreases when compared to expert endoscopists in real-time clinical practice. This is especially evident in non-randomized studies, where AI demonstrates limited real-world benefits despite its benefit in controlled settings. Furthermore, no meta-analyses have specifically examined AI's impact on the learning experience of fellows and residents. Some experts caution that reliance on AI may prevent trainees from developing essential observational skills, potentially leading to less thorough examinations. Further research is needed to determine the actual benefits of AI-colonoscopy, particularly its role in cancer prevention. As technology advances, improved outcomes are expected, especially in detecting small, flat, and lesions at difficult anatomical locations.

Artificial intelligence for reducing missed detection of adenomas and polyps in colonoscopy: A systematic review and meta-analysis

BACKGROUND

Colorectal cancer has a high incidence and mortality rate, and the effectiveness of routine colonoscopy largely depends on the endoscopist’s expertise. In recent years, computer-aided detection (CADe) systems have been increasingly integrated into colonoscopy to improve detection accuracy. However, while most studies have focused on adenoma detection rate (ADR) as the primary outcome, the more sensitive adenoma miss rate (AMR) has been less frequently analyzed.

AIM

To evaluate the effectiveness of CADe in colonoscopy and assess the advantages of AMR over ADR.

METHODS

A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Central Register of Controlled Trials using predefined search strategies to identify relevant studies published up to August 2, 2024. Statistical analyses were performed to compare outcomes between groups, and potential publication bias was assessed using funnel plots. The quality of the included studies was evaluated using the Cochrane Risk of Bias tool and the Grading of Recommendations, Assessment, Development, and Evaluation approach.

RESULTS

Five studies comprising 1624 patients met the inclusion criteria. AMR was significantly lower in the CADe-assisted group than in the routine colonoscopy group (147/927, 15.9% vs 345/960, 35.9%; P < 0.01). However, CADe did not provide a significant advantage in detecting advanced adenomas or lesions measuring 6-9 mm or ≥ 10 mm. The polyp miss rate (PMR) was also lower in the CADe-assisted group [odds ratio (OR), 0.35; 95% confidence interval (CI): 0.23-0.52; P < 0.01]. While the overall ADR did not differ significantly between groups, the ADR during the first-pass examination was higher in the CADe-assisted group (OR, 1.37; 95%CI: 1.10-1.69; P = 0.004). The level of evidence for the included randomized controlled trials was graded as moderate.

CONCLUSION

CADe can significantly reduce AMR and PMR while improving ADR during initial detection, demonstrating its potential to enhance colonoscopy performance. These findings highlight the value of CADe in improving the detection of colorectal neoplasms, particularly small and histologically distinct adenomas.

Prophylactic drain placement after emergency general surgery procedures? A scoping review of the literature challenging common practice

BACKGROUND

This scoping review aims to map the existing literature on the use of prophylactic drainage (PD) after Emergency General Surgery procedures (EGS) and to change the current practice according to evidence.

METHODOLOGY

Data from an exhaustive literature search conducted across Embase (Ovid), Medline(R) ALL (Ovid), Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials was summarized. Literature published between January 2013 and December 2024 was included.

RESULTS

Most studies found better outcomes for the no-drain group. Implementing a drain after EGS procedures potentially increases hospital stays, postoperative pain, and surgical site infection rates. For conditions such as peritonitis and perforated ulcers, only a few studies were available, with some showing benefits of PD.

CONCLUSION

For some conditions, like colorectal emergencies, there is a scarcity of evidence. The outcomes suggest that PD is not recommended in most EGS cases. In high-risk cases, there are some reports on improved outcomes for PD use. Further research is imperative to create science-based clinical guidelines, especially for less-researched conditions.

Vaccination Status is Not Associated With Adverse Postoperative Outcomes Following Total Joint Arthroplasty in Patients With a Preoperative COVID-19 Diagnosis

Background

Previous studies have shown that COVID-19 diagnosis increases rates of perioperative infection, readmission, and other complications following surgery. However, the effect of the COVID vaccine in such patients is unknown. We hypothesized that of the patients with COVID diagnosis, vaccinated patients with COVID-19 diagnosis would have lower rates of adverse complications compared to unvaccinated patients undergoing total joint arthroplasty (TJA).

Methods

Using a national database registry, patients aged less than 85 years undergoing elective primary total knee or total hip arthroplasty with at least 90 days of follow-up were included during the first year of COVID-19 pandemic from April 2020-April 2021. Patients were included in the COVID-19 cohort if they had a diagnosis on the day of surgery or within 30 days prior to surgery. Patients with a history of malignancy, joint injection, femoral neck fractures, tibial fractures, and those undergoing revision arthroplasty were excluded from the study. All comparisons were performed using multivariate logistic regression with significance set at P < .05. Odds ratio and 95% confidence interval were reported for all comparisons.

Results

There were a total of 1280 patients with COVID-19 diagnosis matched with 3831 patients without COVID-19 diagnosis. Patients with a COVID-19 diagnosis were at an increased risk of pneumonia, acute kidney injury, urinary tract infection, and readmission following TJA compared to patients without COVID-19 diagnosis. However, there were no differences in any complications assessed between vaccinated patients and unvaccinated patients with COVID-19 diagnosis following TJA.

Conclusions

This study confirms that patients with a COVID-19 diagnosis in the 30 days prior to TJA, whether vaccinated or not, have increased risks of medical complications and hospital utilization. However, this study demonstrates that vaccination status does not appear to be associated with the incidence of adverse postoperative events in patients with a COVID-19 diagnosis prior to TJA.

Significant Alterations of Colorectal Cancer Care in the COVID-19 Pandemic With High Adherence to Quality Criteria in German Cancer Centers (CC) ‒ Data From the AIO CancerCOVID Consortium (AIO-YMO/KRK 520/ass)

BACKGROUND

Colorectal cancer (CRC) remains a leading cause of death despite notable advancements through guideline-based management. We present data on changes of CRC care during the COVID-19 pandemic in Germany.

METHODS

Retrospective data from 22 AIO CCs and an academic Institute of Pathology compared the first (fw, 03-05.2020) and second wave (sw, 11-12.2020) of the pandemic with corresponding 2019 periods. Parameters were: number of cases diagnosed, age, sex, tumor stage, surgical procedures, quality criteria of CRC care (presentation in multidisciplinary tumor boards (MTB), psychological or social consultation), number of precancerous and malignant colorectal lesions (CRL). Data points were compared as mean values with confidence intervals estimated according to Clopper and Pearson (1934). Hypothesis tests were conducted using Poisson regression models that included interaction terms (year*sex or year*age over70). Statistical significance was considered at P < .05.

RESULTS

A total of 4316 cases diagnosed (AIO CC) revealed a substantial reduction (fw -20.58%; sw -23.48%). Hypothesis test showed a significant decline in incidence due to the fw and sw of the pandemic. Quality criteria of cancer care remained stable except for trial participation. Analysis from 60,695 CRL detected a decrease in precancerous (fw: -16 %/sw: -4 %) and malignant (fw: -18 %) lesions while malignant CRL increased in the sw (+8 %). Hypothesis test revealed a significant decline only for the fw 2020 and detected age > 70 as independent risk factor in both waves.

CONCLUSION

We detected substantial alterations in cancer care during the pandemic, including detected precancerous CRL. CCs showed high resilience in quality criteria for CRC care.

Hand-Assisted Laparoscopic Surgery (HALS) as an Alternative to Unplanned Laparoscopic Conversion to Open Surgery (LCOS) in Colectomies for Acute Diverticulitis

BackgroundIn difficult colorectal cases, surgeons may opt for a hand-assisted laparoscopic (HALS) colectomy or attempt a laparoscopic surgery that may require an unplanned conversion to open (LCOS). We aimed to compare the clinical outcomes of these 2 types of surgeries.MethodsColectomies for acute diverticulitis with a HALS or LCOS surgery were selected from the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) 2022 Targeted Colectomy Database. After confirming a difference in propensity scores between the cohorts, they were matched using propensity score matching (PSM) based on preoperative factors. RStudio was utilized for filtering and performing the PSM, while Minitab was used for statistical analysis.ResultsWe identified 804 HALS colectomies and 284 LCOS colectomies. After PSM, both cohorts contained 284 patients. Absolute standardized mean errors for all matched factors were less than 0.1, confirming well-balanced cohorts. Following PSM, preoperative and perioperative factors were similar between both colectomy groups. Postoperatively, HALS surgeries had a shorter average length of stay (7.67 ± 0.38 vs 10.57 ± 0.41, P < 0.001) as well as lower rates of ileus (13.73% vs 22.54%, P = 0.007) and superficial surgical site infection (2.11% vs 5.28%, P = 0.045).ConclusionTo the best of our knowledge, this is the first national database study comparing HALS and LCOS colectomies. After accounting for confounding variables, our PSM analysis showed the benefits of HALS colectomies for acute diverticulitis. Future studies may use single-center data containing risk adjustment profiles to create an even more uniform comparison.

Challenges and Strategies in Maintaining Continuity of Care for Chronic Disease Patients by Emergency Nurses During Disasters

AIM

This study aimed to explore the challenges emergency nurses face in providing continuity of care for chronic disease patients during disasters in the Northern Region of Saudi Arabia and the strategies they employ to overcome these challenges.

BACKGROUND

Emergency nurses play a pivotal role in disaster response, particularly in managing care for patients with chronic diseases. Resource shortages, communication breakdowns, and patient displacement frequently disrupt care continuity during disasters, exacerbating health risks for vulnerable populations.

INTRODUCTION

Ensuring consistent care for chronic disease patients during disasters is critical for mitigating negative health outcomes. Disruptions caused by disasters highlight the need for strategies that support emergency nurses in maintaining care standards under resource-limited and high-stress conditions.

METHODS

A qualitative descriptive study was conducted using semistructured interviews with 14 emergency nurses from a general hospital in the Northern Region of Saudi Arabia. Thematic analysis, adhering to COREQ guidelines, was applied to identify key challenges and solutions.

RESULTS OR FINDINGS

Three key themes were identified: resource limitations, communication barriers, and patient displacement. Nurses reported challenges such as shortages of essential medications, disruptions in communication networks, and difficulties in maintaining continuity of care for displaced patients. To mitigate these challenges, they employed strategies including improvisation, enhanced communication protocols, and resilience-building practices.

DISCUSSION

The findings highlight the critical role of emergency nurses in disaster response and the necessity of adaptive practices. Addressing resource scarcity, fostering robust communication systems, and supporting nurse well-being are essential to maintaining care quality during disasters.

CONCLUSION AND IMPLICATIONS FOR NURSING AND/OR HEALTH POLICY

Emergency nurses require robust support systems to maintain care continuity during disasters. Policymakers should integrate disaster preparedness into healthcare frameworks by enhancing resource allocation, developing resilient communication infrastructure, and providing targeted training programs. These measures can improve nurse capacity, optimize patient outcomes, and strengthen health systems' disaster response capabilities.

Chemotherapy/Radiotherapy-Induced Dysphagia in Head and Neck Tumors: A Challenge for Otolaryngologists in Low- to Middle-Income Countries

Head and neck cancer accounts for 2.8% of all cancers and a large proportion of these patients have a locally advanced stage of the disease, for which chemotherapy and radiation therapy are potentially curative treatments. Dysphagia is one of the most common chemoradiotherapy-related side effects in head and neck cancer since it can lead to life-threatening complications. Reports from the current literature suggest better swallowing outcomes with intensity-modulated radiotherapy (IMRT) compared to three-dimensional conformal radiotherapy (3DCT). However, in low-/middle-income countries, multiple healthcare access barriers to 3DCT that may lead to higher rates of chemo/radiotherapy related adverse events. This narrative review provides a comprehensive appraisal of published peer-reviewed data, as well as a description of the clinical practice in an otolaryngology referral center in Colombia, a low-income country.

Advancements in targeting tumor suppressor genes (p53 and BRCA 1/2) in breast cancer therapy

Globally, among numerous cancer subtypes, breast cancer (BC) is one of the most prevalent forms of cancer affecting the female population. A female's family history significantly increases her risk of developing breast cancer. BC is caused by aberrant breast cells that proliferate and develop into tumors. It is estimated that 5-10% of breast carcinomas are inherited and involve genetic mutations that ensure the survival and prognosis of breast cancer cells. The most common genetic variations are responsible for hereditary breast cancer but are not limited to p53, BRCA1, and BRCA2. BRCA1 and BRCA2 are involved in genomic recombination, cell cycle monitoring, programmed cell death, and transcriptional regulation. When BRCA1 and 2 genetic variations are present in breast carcinoma, p53 irregularities become more prevalent. Both BRCA1/2 and p53 genes are involved in cell cycle monitoring. The present article discusses the current status of breast cancer research, spotlighting the tumor suppressor genes (BRCA1/2 and p53) along with structural activity relationship studies, FDA-approved drugs, and several therapy modalities for treating BC. Breast cancer drugs, accessible today in the market, have different side effects including anemia, pneumonitis, nausea, lethargy, and vomiting. Thus, the development of novel p53 and BRCA1/2 inhibitors with minimal possible side effects is crucial. We have covered compounds that have been examined subsequently (2020 onwards) in this overview which may be utilized as lead compounds. Further, we have covered mechanistic pathways to showcase the critical druggable targets and clinical and post-clinical drugs targeting them for their utility in BC.

Understanding the Impact of Ostomy Dejecta Constituents on Peristomal Skin Health and Models for Its Characterisation

An ostomy, or stoma, is a surgically created percutaneous aperture from a hollow organ (e.g., small intestine) to the body's surface. Physicians may recommend an ostomy as a temporary or permanent solution to a range of disorders of the gastrointestinal tract, with up to 130 000 ostomies performed annually in the United States. An ostomy facilitates the expulsion of waste products, termed dejecta and circumvents the compromised organs. While an ostomy can be a lifesaving treatment, it is a disruption of regular digestive flow and has a number of associated complications including hernia, prolapse and necrosis. The most commonly observed complications are peristomal skin complications (PSCs), attributed to the leakage of dejecta onto the peristomal skin or the skin directly surrounding the stoma. Despite the prevalence of PSCs, little is known about the precise etiological factors that play a role in PSC formation. This review discusses the constituents of dejecta and their possible roles in PSC formation. Additionally, we identify a number of in vitro and in vivo skin models that could be used to study PSCs. Identification of the components of dejecta and understanding their interaction with skin models can facilitate the development of interventions to treat and prevent PSCs.

PErioperative respiratory care aNd outcomes for patients underGoing hIgh risk abdomiNal surgery (PENGUIN): a randomised international internal pilot trial

Background

Infections are a common complication of abdominal surgery in low- and middle-income countries (LMICs). The role of a high fraction of inspired oxygen (FiO2) and chlorhexidine mouthwash in preventing post-operative infections is unconfirmed.

Methods

Internal pilot phase of an international outcome assessor-blinded, 2x2 factorial randomised trial of patients aged ≥10-years undergoing midline laparotomy in LMIC hospitals. The main trial objectives are to compare the clinical effectiveness of preoperative 0.2% chlorhexidine mouthwash in preventing pneumonia versus no mouthwash, and 80-100% perioperative FiO2 to prevent surgical site infection (SSI) versus 21-35% FiO2. This 12-month internal pilot assessed feasibility of hospital site opening, patient recruitment, intervention adherence, patient follow-up and safety. Patients were randomised in a 1:1:1:1 ratio to the four intervention group combinations and followed up for 30 days.

Results

We recruited 927 patients from seven hospitals in India and South Africa over 12 months from November 2020. There were 907 adults (97.8%) and 20 children aged ten or over (2.2%): 89/927 (9.6%) patients died. Site opening reached 70% of our target (7/10) hospitals, and patient recruitment 107% (927/870). 917/927 (99%) patients in the mouthwash arm, and 840/927 (91%) patients in the oxygen arm received the allocated intervention. Lower adherence to the oxygen intervention related mainly to clinically necessary FiO2 increases in the 21-35% FiO2 arm. 30-day follow-up was completed appropriately for 924/927 (99%) patients. and was performed by a masked assessor for all patients. There were no reported safety events.

Conclusion

This pilot showed the feasibility and safety of a major phase III trial in post-operative infection prevention in LMICs.

Phellodendrine Exerts Protective Effects on Intra-abdominal Sepsis by Inactivating AKT/NF-kB Signaling

Acute kidney injury (AKI) and acute lung injury (ALI) are major complications of intra-abdominal sepsis, leading to increased mortality. Phellodendrine (PHE) is a characteristic and important active ingredient of Phellodendri Cortex, possessing multiple pharmacological properties. This study intends to explore the effect of PHE on intra-abdominal sepsis-induced AKI and ALI. An intra-abdominal infection-induced rat model of sepsis was established by fecal intraperitoneal injection, followed by the administration of PHE. ELISA was used to determine plasma levels of inflammatory cytokines. Hematoxylin-eosin, Periodic acid Schiff, and Masson trichrome staining were employed for histopathological analysis of rat kidney and lung tissues. Western blotting was used to estimate the AKT/NF-κB signaling-related protein levels. The results showed that PHE improved the survival rate of septic rats and reduced plasma levels of proinflammatory cytokines. PHE administration attenuated pathological lesions in the kidneys and lungs of septic rats. Mechanistically, PHE treatment blocked AKT/NF-κB signaling in septic rats' kidneys and lungs. In conclusion, PHE ameliorates intra-abdominal sepsis-induced kidney and lung injury possibly by inactivating AKT/NF-kB signaling.

Silver trauma: is whole body CT warranted in low impact trauma

OBJECTIVES

Trauma in the elderly is associated with high mortality. Elderly people who have suffered low impact trauma, such as fall from standing (FFS) are believed still to be at high risk of injury. Whole body trauma CT (WBCT) is increasingly used to image such people, to prevent missing injuries which are not detected clinically. This study aims to assess the utility of WBCT in assessing elderly people who have suffered FFS.

METHODS

Over a 2-year period in a single health board, data were collected retrospectively for all patients that underwent WBCT. Data were collected on the mechanism, pattern of injury, and outcomes including 30-day mortality using clinical records. Comparison was made between pre-CT clinical suspicion and injury found on WBCT to identify discrepancies.

RESULTS

In total, 460 patients were included in this study. Compared with FFS, fall from more than standing was associated with higher adjusted odds of having an injury out with zone of clinical suspicion (Adjusted Odds Ratio (AOR) 2.80, 95% CI 1.23-7.28; P = .021). There was no significant difference in 30-day mortality between patients who had an injury on WBCT and those without.

CONCLUSIONS

FFS is associated with a reduced risk of injury out with areas of clinical concern when compared with fall from greater than standing. As such, a targeted approach to CT scanning in these patients could be considered.

ADVANCES IN KNOWLEDGE

This study challenges the current prevailing dogma for the requirement of WBCT in elderly people who suffer FFS, providing evidence that such people have a low risk of injuries out with areas of clinical suspicion.

SAGES white paper on antibiotic omission in the management of acute uncomplicated diverticulitis: why, when, who, and most importantly, how

BACKGROUND

Historically, the management of acute uncomplicated diverticulitis was centered on antibiotics. However, modern theories regarding the pathogenesis of diverticulitis have challenged the notion that antibiotics are necessary in all cases. Despite major reform in many societal guidelines, the adoption of non-antibiotic therapy for uncomplicated diverticulitis has been limited, especially in North America. The purpose of this SAGES White Paper was to review the available evidence on antibiotic omission in uncomplicated diverticulitis and to explore methods of safe implementation.

METHODS

A task force within the SAGES Colorectal Surgery Committee was formed to work on this White Paper. The committee and its leadership approved an outline that would focus on the following topics: (1) Defining the problem with unnecessary antibiotic exposure; (2) Evaluating the evidence on antibiotic omission in uncomplicated diverticulitis; (3) Identifying the appropriate patient for antibiotic omission; (4) Outlining how to counsel patients who are treated without antibiotics; (5) Reviewing methods to safely implement this practice in both the hospital and community setting. These topics were divided up among members of the task force who performed a structured literature search in preparation for their assignments.

RESULTS

Antibiotics are associated with several patient and societal adverse effects, including the rising problem of antimicrobial resistance. Randomized controlled trials have demonstrated no superiority to the routine administration of antibiotics in acute uncomplicated diverticulitis. Appropriate patients for antibiotic omission include those who are immunocompetent, non-septic, and have mild symptoms/disease severity on imaging. Existing frameworks for the safe implementation of new practices can be referenced to help increase adoption of non-antibiotic therapy.

CONCLUSION

The existing body of evidence supports antibiotic omission in appropriate cases of acute uncomplicated diverticulitis. In order to increase the widespread adoption of this practice, buy-in from key stakeholders (both healthcare professionals and patients) is necessary.

Hepatic Portal Venous Perfusion Imaging Using Vessel-Labeling Super-Resolution Ultrasound

OBJECTIVE

Blood flow imaging and perfusion assessment of the hepatic portal vein are critical for the diagnosis of several liver diseases, including cirrhosis, primary and metastatic liver tumors. However, perfusion imaging of the portal vein is challenging due to the unique dual blood supply system of the liver.

METHODS

We developed a novel method for specific perfusion imaging of the portal vein and downstream vessels, which was validated on healthy mice (n = 4). The right lobe of the liver in healthy mice was sequentially imaged using ultrafast plane-wave Doppler imaging and vascular labeling. In each experiment, mice were first injected with phase-change nanodroplets (PCNDs), followed immediately by ultrafast Doppler imaging to determine the imaging section and locate portal vein branches. Through an interactive process, portal vein branches were selected by mouse click for data acquisition of vessel-labeling ultrasound (VLUS) based on PCNDs. Subsequent arrival time calculations and super-resolution ultrasound (SRUS) imaging were performed offline. To demonstrate the specificity of the proposed method for vascular imaging, one mouse was injected with Sonovue microbubbles for plane-wave ultrasound data acquisition and microbubble-based VLUS data acquisition. All imaging experiments were conducted on the Verasonics (Kirkland, WA, USA) Vantage 256 ultrasound system using an L22-8v linear array transducer with a center frequency of 15.625 MHz. The multi-angle coherent compounding plane-wave acquisition frame rate was 500 Hz.

RESULTS

Imaging results from healthy mice (n = 4) demonstrated that VLUS was able to label different branches of the hepatic portal vein and specifically image downstream vessels. Analysis of the in vivo results at different spatial scales showed that the brightness of the downstream perfusion area was significantly enhanced after labeling started, while there was no significant difference in image brightness before the labeling started and after it ended. By analyzing the acoustic field distribution at the focal point, the full width at half maximum in the x1 and z1 directions were 98.56 μm and 526.68 μm, respectively. Along the propagation path of the focused beam (outside the labeling area), no significant activation of the PCNDs was observed (p < 0.0001). Combined with SRUS technology, the resolution of the VLUS portal vein imaging results was further enhanced. The time-intensity curves of the downstream regions of interest indicated that VLUS provided a step input signal to the downstream vessels. Based on the arrival time of the step point in the time-intensity curves, the arrival time distribution map of the downstream vessels relative to the labeling point could be calculated.

CONCLUSION

We propose a novel method for hepatic portal vein perfusion imaging based on VLUS. In vivo experiments, simulation results and statistical analysis demonstrate that this method is able to accurately label portal vein vessels with millimeter-level precision, enabling specific high-resolution imaging and precise, non-invasive measurement of the downstream perfusion area. By combining VLUS with SRUS technology, the resolution of the portal vein imaging results can be further enhanced.

The Severity of Appendicitis During the COVID-19 Pandemic: A Single Institution Experience

IntroductionThe COVID-19 pandemic led to nationwide stay at home orders, leading to delays in medical care. We sought to identify if the severity of appendicitis changed during the pandemic due to these delays and if there were differences in appendicitis severity in patients with simultaneous COVID-19 infection. We hypothesized that pandemic-related restrictions led to more severe cases of appendicitis.MethodsWe performed a retrospective study (4/2018-4/2022) of all patients ≥ 5y with appendicitis. Patients with a malignant appendiceal specimen were excluded. Clinical outcomes and characteristics were compared in those with appendicitis prior to the COVID-19 (PC) era to those in the COVID-19 (C) era, as well as between COVID-19 positive (C+) and negative (C-) individuals. Univariate analyses were conducted. A P-value <0.05 was considered to be statistically significant.ResultsA total of 1665 patients met inclusion criteria, 806 (48.4%) in PC era, and 859 (51.6%) in C era. Age and gender did not differ from PC era to C era, nor did they differ from the C- group to the C+ group. The C era had significantly higher 30-day readmissions than the PC era (C 6.29% (n = 54) v. PC 2.73% (n = 22), P = 0.001). The C era also had more greater than 30-day readmissions than the PC era (C 3.26% (n = 28) v. PC 1.74% (n = 14), P = 0.048). There was no significant difference in the reason for 30-day or greater than 30-day readmissions for the PC vs C eras. Of the C era, 833 (97.0%) were C- and 26 (3.0%) were C+. Rates of nonoperative management at index admission were not different between groups. The white blood cell (WBC) count was significantly lower in C+, 11.9 (8.55-13.35 IQR), vs C- group, 12.85 (9.9-15.3 IQR), P = 0.0336. There was no significant difference in the severity of appendicitis nor readmission status in C+ vs C- groups during the C era.ConclusionOur data indicates that the PC era had more severe cases of appendicitis as shown by higher rates of perforated and gangrenous appendicitis on pathology reports compared to the C era. Interestingly, readmissions were more prevalent in the C era as opposed to the PC era, which coincided with an increase in complications requiring readmission following laparoscopic appendectomies. In evaluating appendicitis patients according to COVID-19 status, we saw no significant differences in the severity of appendicitis in C- and C+ individuals.

Outcomes After Elective Versus Emergency Resection for Right-Sided Colon Cancer: A Propensity Score-Matched Analysis

BACKGROUND

Previous studies reported similar complication rates, including anastomotic leakage, after elective and emergency surgery for right-sided colon cancer. This led to the consensus that emergency resection with primary anastomosis is safe. However, recent evidence suggests higher complication rates after emergency surgery, indicating that alternative strategies, such as a bridge to surgery, may be more suitable.

OBJECTIVE

To assess whether complication rates, particularly anastomotic leakage, are higher after emergency resections compared to elective resections in patients with right-sided colon cancer.

DESIGN

A retrospective cohort study using data from the Dutch ColoRectal Audit from 2010 to 2019.

SETTINGS

Nationwide data from hospitals across the Netherlands.

PATIENTS

Patients who underwent resection for right-sided colon cancer (n = 5056 emergency resections matched 1:1 to elective resections using propensity score matching).

MAIN OUTCOME MEASURES

Incidence of anastomotic leakage, 90-day complication rates, and mortality rates after elective versus emergency surgery for right-sided colon cancer.

RESULTS

After matching, no significant baseline differences remained. There was no significant difference in anastomotic leakage rates. However, the mortality rate was twice as high in the emergency group (9.4% vs 4.2%, p < 0.001), and the 90-day complication rate was also higher (41.7% vs 33.0%, p < 0.001).

LIMITATIONS

Minimal missing data were handled with multiple imputation. Although propensity score matching was used, bias from unknown confounders may persist. The emergency group included more high-risk patients, potentially influencing outcomes.

CONCLUSIONS

Emergency resections for right-sided colon cancer are associated with higher complication and mortality rates compared to elective surgery. A bridge-to-surgery approach could reduce these risks by converting emergency cases to elective procedures. Further research is needed to validate these findings. See Video Abstract.

RESULTADOS TRAS LA RESECCIN ELECTIVA FRENTE A LA RESECCIN DE EMERGENCIA PARA CNCER DE COLON DEL LADO DERECHO UN ANLISIS DE PUNTUACIN DE PROPENSIN COINCIDENTE

ANTECEDENTES:Estudios previos informaron tasas de complicaciones similares, incluida la fuga anastomótica, después de una cirugía electiva y de emergencia para el cáncer de colon del lado derecho. Esto llevó al consenso de que la resección de emergencia con anastomosis primaria es segura. Sin embargo, evidencia reciente sugiere tasas de complicaciones más altas después de la cirugía de emergencia, lo que indica que las estrategias alternativas, como un puente a la cirugía, pueden ser más adecuadas.OBJETIVO:Evaluar si las tasas de complicaciones, en particular la fuga anastomótica, son más altas después de las resecciones de emergencia en comparación con las resecciones electivas en pacientes con cáncer de colon del lado derecho.DISEÑO:Un estudio de cohorte retrospectivo que utiliza datos de la Dutch ColoRectal Audit de 2010 a 2019.ESCENARIO:Datos a nivel nacional de hospitales de los Países Bajos.PACIENTES:Pacientes que se sometieron a una resección por cáncer de colon del lado derecho (n = 5056 resecciones de emergencia emparejadas 1:1 con resecciones electivas mediante emparejamiento por puntaje de propensión).PRINCIPALES MEDIDAS DE VALORACIÓN:Incidencia de fuga anastomótica, tasas de complicaciones a los 90 días y tasas de mortalidad después de cirugía electiva versus cirugía de emergencia para cáncer de colon del lado derecho.RESULTADOS:Después del emparejamiento, no se mantuvieron diferencias significativas al inicio. No hubo diferencias significativas en las tasas de fuga anastomótica. Sin embargo, la tasa de mortalidad fue dos veces más alta en el grupo de emergencia (9,4% frente a 4,2%, p < 0,001) y la tasa de complicaciones a los 90 días también fue mayor (41,7% frente a 33,0%, p < 0,001).LIMITACIONES:Los datos faltantes mínimos se manejaron con imputación múltiple. Si bien se utilizó el emparejamiento por puntaje de propensión, puede persistir el sesgo de factores de confusión desconocidos. El grupo de emergencia incluyó más pacientes de alto riesgo, lo que potencialmente influyó en los resultados.CONCLUSIONES:Las resecciones de emergencia para cáncer de colon del lado derecho se asocian con mayores tasas de complicaciones y mortalidad en comparación con la cirugía electiva. Un enfoque de puente a la cirugia podría reducir estos riesgos al convertir los casos de urgencia en procedimientos electivos. Se necesitan más investigaciones para validar estos hallazgos.

Antimicrobial resistance: Linking molecular mechanisms to public health impact

BACKGROUND

Antimicrobial resistance (AMR) develops into a worldwide health emergency through genetic and biochemical adaptations which enable microorganisms to resist antimicrobial treatment. β-lactamases (blaNDM, blaKPC) and efflux pumps (MexAB-OprM) working with mobile genetic elements facilitate fast proliferation of multidrug-resistant (MDR) and exttreme drug-resistant (XDR) phenotypes thus creating major concerns for healthcare systems and community health as well as the agricultural sector.

OBJECTIVES

The review dissimilarly unifies molecular resistance pathways with public health implications through the study of epidemiological data and monitoring approaches and innovative therapeutic solutions. Previous studies separating their attention between molecular genetics and clinical outcomes have been combined into our approach which delivers an all-encompassing analysis of AMR.

KEY INSIGHTS

The report investigates the resistance mechanisms which feature enzymatic degradation and efflux pump overexpression together with target modification and horizontal gene transfer because these factors represent important contributors to present-day AMR developments. This review investigates AMR effects on hospital and community environments where it affects pathogens including MRSA, carbapenem-resistant Klebsiella pneumoniae, and drug-resistant Pseudomonas aeruginosa. This document explores modern AMR management methods that comprise WHO GLASS molecular surveillance systems and three innovative strategies such as CRISPR-modified genome editing and bacteriophage treatments along with antimicrobial peptides and artificial intelligence diagnostic tools.

CONCLUSION

The resolution of AMR needs complete scientific and global operational methods alongside state-of-the-art therapeutic approaches. Worldwide management of drug-resistant infection burden requires both enhanced infection prevention procedures with next-generation antimicrobial strategies to reduce cases effectively.

Effect of age on major trauma profile and characterisation: Analysis from the national major trauma audit in Ireland

BACKGROUND

Major trauma (MT) is a significant cause of morbidity and mortality worldwide, with older adult patients facing unique challenges due to age-related vulnerabilities and higher risks of falls. This study aimed to investigate differences in trauma characteristics, injury mechanisms, and outcomes of older adults compared to all younger patients with MT on a national level.

METHODS

This retrospective cohort study analysed the national Major Trauma Audit data from 23,765 eligible patients with MT in Ireland of all ages and stratified into two age groups: those under 65 years (n = 12,620) and those aged 65 years or older (n = 11,145). The Major Trauma Audit follows the methodology of National Major Trauma Registry in the UK. Variables assessed included injury severity, comorbidities, length of stay (LOS), and mortality rates. Statistical comparisons were made between the two age groups.

RESULTS

Older adults represent 47 % of the total Irish patient population with MT, with a significantly higher proportion of females (56 %) compared to younger patients (31 %) (P<0.001). Falls of less than two meters were the leading mechanism of injury for older adults (82 %), while road traffic accidents (RTA) were more common among younger patients (25 %). Severe injuries were observed in 34 % of both age groups, but <10 % of older adults were received by a trauma team. Comorbidities were significantly more prevalent in older adults (75 %) compared to 39 % in younger patients, (P<0.001). Median hospital LOS was twelve days for older adults, compared to seven days for younger patients. Mortality rates were significantly higher among the older patient population, who were also more likely to be discharged to long-term care, (P<0.001).

CONCLUSION

In comparison to younger patients, the present study highlights that older adults who experience major trauma are frequently under-triaged as suspected MT, leading to delays in care, inadequate treatment, or worse clinical outcomes.

An Australian regional hospital's oesophagectomy experience: A 10-year case series from Tasmania

Introduction

Oesophagectomy is recommended as part of curative treatment for oesophageal cancer but is associated with substantial morbidity. Centralization has been recommended to improve outcomes, but this has not been widely applied in Australia. This study aimed to audit a regional hospital's experience over ten years and compare it to outcomes from national and international centres to support the view that oesophagectomy can be performed safely in select regional centres in Australia.

Methods

Patients undergoing oesophagectomy at a single regional hospital in North-East Tasmania, Australia between January 2014 and December 2023 were retrospectively identified. Preoperative patient and tumour characteristics, and outcomes (mortality, anastomotic leak, length of stay, respiratory complications, long-term complications and survival) were compared to other centres.

Results

65 patients were identified. 53 % were male, mean age was 65.2 years, 29.2 % had respiratory disease and 18.5 % were current smokers. The anastomotic leak rate was 7.7 %. 25 % developed pneumonia postoperatively. Average ICU length of stay was 4.6 days, median acute inpatient length of stay was 15 days. There was one in-hospital mortality and one 30-day mortality. 2 patients (3 %) required diaphragmatic hernia repair; 12 patients (18.5 %) required endoscopic dilatation of anastomotic strictures. The 5-year survival rate was 66 %. Our results compare favourably to published rates of anastomotic leak (10-15 %), inpatient stay (15 days), pneumonia (20-30 %), 30-day mortality (1-4 %) and anastomotic stricture (20 %).

Conclusions

Oesophagectomies can be safely performed in regional centres in Australia that routinely undertake a higher volume of cases per year, provided services required to manage complications are readily available.

From the operating room: Surgeons' views on difficult laparoscopic cholecystectomies

Backgrounds/Aims

Assessing surgical difficulty in laparoscopic cholecystectomy (LC) is challenging due to variations in surgeon proficiency and institutional protocols. This study evaluates surgeons' perspectives on procedural difficulty and examines how intraoperative findings and preoperative imaging contribute to refining difficulty assessment criteria.

Methods

A cross-sectional survey was conducted among 50 laparoscopic surgeons in India, providing insights into tolerances for surgical duration and blood loss, reasons for conversion, and predictors of complexity. Responses were analyzed using SPSS, with statistical significance set at p < 0.05.

Results

Among surveyed surgeons, 82.0% were male, and 78.0% worked in private institutions and 52.0% had performed over 1,000 LCs. Conversion to open surgery was primarily influenced by significant blood loss (68.0%) and biliary injury (94.0%). While 38.0% preferred surgeries under 60 minutes, 26.0% imposed no time constraints. Key intraoperative challenges included dense adhesions, cholecysto-enteric fistulas, and fibrosis. Less experienced surgeons reported greater challenges with scarring adhesions and anatomical variations, but no significant differences were found for other factors like edematous or necrotic changes. Preoperative imaging was considered essential by most surgeons.

Conclusions

This study underscores the limited reliability of traditional parameters for assessing difficulty in LC. Surgeons highlighted the importance of objective intraoperative findings and preoperative imaging in predicting surgical challenges. Factors such as adhesions, fibrosis, and anatomical variations significantly impact LC difficulty, with decisions regarding conversion to open surgery largely driven by individual judgment rather than experience. Standardized grading systems incorporating these factors could improve surgical planning, reduce complications, and enhance patient outcomes.

Safety and efficacy of gastrointestinal motility agents following elective colorectal surgery: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Postoperative ileus (POI) is a frequent complication after elective colorectal surgery, delaying gastrointestinal (GI) recovery and discharge. While pharmacologic agents such as laxatives and prokinetics are often included in enhanced recovery after surgery (ERAS) protocols, their efficacy and safety remain uncertain.

METHODS

A systematic review and meta-analysis of randomised controlled trials (RCTs) was conducted to evaluate the effect of Gastrointestinal (GI) motility agents on postoperative recovery in elective colorectal surgery. Primary outcomes included GI-2 recovery (tolerance of solid diet and stool passage), time to first defaecation, and safety endpoints. Data was pooled using random-effects models.

RESULTS

Seven RCTs involving 849 patients were included. GI motility agents significantly accelerated GI-2 recovery (mean difference -1.01 days; 95% CI -1.29 to -0.73; p < 0.001) and reduced time to first defaecation (mean difference -1.07 days; 95% CI -1.40 to -0.73; p < 0.001). No significant differences were observed in safety outcomes, including anastomotic leak (OR 0.97; 95% CI 0.53 to 1.77), nasogastric tube reinsertion (OR 0.86; 95% CI 0.49 to 1.51), or readmission rates (OR 1.03; 95% CI 0.62 to 1.72).

CONCLUSION

Motility agents enhance postoperative GI recovery without compromising safety in patients undergoing elective colorectal surgery. Given their low cost, wide availability, and favourable safety profile, gastrointestinal motility agents may be considered for integration into ERAS protocols. However, further high-quality, standardised trials are needed to confirm their benefits across diverse surgical populations.

Hospital Ownership and Surgical Outcomes in East, Central, and Southern Africa

Importance

Surgical mortality remains a critical public health issue in resource-limited settings. Hospital ownership type may influence surgical outcomes, yet this relationship is not well understood in East, Central, and Southern Africa, where a diverse mix of public, private, and faith-based hospitals provides care.

Objective

To determine whether hospital ownership type (public, private, or faith-based) is associated with differences in surgical mortality rates in East, Central, and Southern Africa.

Design, Setting, and Participants

This retrospective cohort study analyzed operative cases recorded by 214 general surgery trainees enrolled in surgical training programs at 85 public, private, and faith-based hospitals in East, Central, and Southern Africa from January 1, 2005, to December 31, 2020. Cases were documented in mandatory operative logbooks. Reported mortalities were analyzed using multilevel logistic regression to account for clustering by trainee while controlling for age category, emergency status, case complexity, specialty type, country Human Development Index, trainee postgraduate year, and self-reported autonomy. Data were analyzed in July 2024.

Exposures

Hospital ownership type categorized as public, private, or faith-based.

Main Outcomes and Measures

The primary outcome was perioperative mortality, defined as in-hospital, all-cause mortality before discharge. Mortality rates were compared across hospital types.

Results

Of the 106 106 operative cases analyzed, 48 474 (45.7%) were performed in public, 3507 (3.3%) in private, and 54 125 (51.0%) in faith-based hospitals. Patients' median (IQR) age was 34 (20-51) years, and 61.5% were male. The overall perioperative mortality rate was 1.6% (95% CI, 1.5%-1.6%). Among major cases (mortality, 1138 of 53 718 [2.1%; 95% CI, 2.0%-2.2%]), faith-based hospitals had 57% lower mortality (518 of 35 370 [1.5%; 95% CI, 1.3%-1.6%]) than public hospitals (589 of 17 223 [3.4%; 95% CI, 3.2%-3.7%]) and 47% lower mortality than private hospitals (31 of 1125 [2.8%; 95% CI, 1.9%-3.9%]). Mixed-effects logistic regression revealed that faith-based hospitals had lower odds of mortality compared with public hospitals (odds ratio, 0.67; 95% CI, 0.51-0.86; P = .002) and private hospitals (odds ratio, 0.57; 95% CI, 0.34-0.95; P = .03).

Conclusions

In this study, faith-based hospitals in East, Central, and Southern Africa were associated with significantly lower surgical mortality rates compared with public and private hospitals. These findings suggest that practices and resources in faith-based hospitals contribute to improved surgical outcomes, warranting further investigation to inform health care policy and improve surgical care and outcomes in the region.

Short-term impact of delayed surgical treatment on the prognosis of patients with T1bN1-stage PTC: a retrospective cohort study

BACKGROUND

As the incidence of papillary thyroid carcinoma (PTC) increases, optimal timing for surgical interventions remains undefined. While surgical delays are known to affect prognosis adversely in various cancers, their impact on PTC is controversial.

METHODS

A retrospective study was conducted on 478 T1bN1-stage PTC patients treated at West China Hospital from January 2020 to May 2022. Patients underwent thyroidectomy with lymph node dissection and were categorized into three groups based on surgical delay: ≤90 days (group A, n = 264), > 90-180 days (group B, n = 92), and > 180 days (group C, n = 122). Additionally, patients were reclassified into two groups based on a one-year threshold: ≤365 days (group D, n = 420) and > 365 days (group E, n = 58). Tumor metastasis rates and postoperative complications were analyzed across these groups.

RESULTS

The median surgical delay was 79 days, and the median follow-up was 1362 days. Tumor metastasis occurred in 1.67% (8 patients), while postoperative complications occurred in 5.65% (27 patients). Metastasis rates were 1.89%, 1.09%, and 1.64%, and complication rates were 5.68%, 4.35%, and 6.56% for groups A, B, and C, respectively. No statistically significant differences were observed in metastasis or complication rates among the three groups. Similarly, no significant differences were found between groups D and E in tumor metastasis (p = 1.000) or complication rates (p = 0.555).

CONCLUSION

Delayed surgery was not associated with significantly increased short-term tumor metastasis or postoperative complication rates in patients with T1bN1-stage PTC.

Etiological treatment of gallstone acute pancreatitis

Gallstone pancreatitis is the leading cause of acute pancreatitis, accounting for more than 40% of cases. Etiological treatment is a critical issue in acute biliary pancreatitis as it helps reduce the risk of recurrence. Patients who have experienced a complicated form of biliary disease are at high risk for recurrent episodes, and the severity of these new episodes can be unpredictable. In recent years, the role and timing of cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP), which are the main therapeutic interventions in the etiological treatment, have been considerably clarified. This review aims to detail the different aspects of the etiological treatment of acute biliary pancreatitis. Currently, it is established that cholecystectomy should be performed early during the initial hospitalization in cases of non-severe acute pancreatitis. However, the optimal timing of this procedure in severe acute pancreatitis remains a subject of debate. Emergency ERCP is no longer indicated for acute biliary pancreatitis, except in cases of associated acute cholangitis. ERCP can be useful for the management of persistent bile duct stones. Finally, the role of interval sphincterotomy in frail or elderly patients or to reduce the risk of recurrence in those awaiting cholecystectomy in cases of severe acute pancreatitis remains to be fully established.

Surveillance and follow-up in acute diverticulitis with pericolic free gas (ADiFas II): an age-specific analysis

The objective of this study was to examine the differences in clinical presentation and complications during the first year of follow-up in patients who experienced an episode of acute diverticulitis (AD) with pericolic free gas, comparing outcomes across different age groups. A prospective subanalysis was conducted on a cohort from the ADiFAS study, which originally included 1099 patients. After excluding 289 patients who did not meet the inclusion criteria, 810 patients remained for analysis. From this cohort, 330 patients with AD and pericolic free gas were selected using propensity score matching and divided into two age groups: < 65 years and ≥ 65 years. The groups were matched based on sex, BMI, diabetes mellitus (DM), cardiovascular disease, previous episodes of AD, and the presence of free fluid on CT scan. Data were assessed for Hinchey classification, surgical procedures, complications, and the frequency of surveillance through colonoscopy and CT scans. The study found a significantly higher rate of surgery in the older group during the index episode (17% vs. 4.2%, p = 0.000). A higher proportion of patients in the older group were misclassified as Hinchey II (18.2% vs. 6.4%, p = 0.007) and Hinchey III (2.3% vs. 0.7%, p = 0.304). All patients classified as Hinchey III (1 in the younger group and 3 in the older group) underwent emergency surgery. In the younger group, 2 out of 8 emergency surgeries were for patients classified as Hinchey II, compared to 11 out of 28 in the older group. Only 58% of patients underwent any form of imaging or endoscopic surveillance during the first year of follow-up. Among those, complications such as abscess, fistula, or stenosis were observed in 17% of patients, occurring more frequently in the older group (16.9% vs. 5.7%, p = 0.089). Nearly 50% of these patients required surgery, with 6 cases in the younger group and 9 in the older group. Emergency surgeries were more common in the older group (2.4% vs. 0.6%, p = 0.186), as was elective surgery (10.3% vs. 7.9%, p = 0.283). A conservative approach, combined with meticulous monitoring through regular follow-ups and imaging, can be effectively employed in managing patients with acute diverticulitis and pericolic free gas. However, our findings highlight the critical need for rigorous surveillance, especially in older patients, due to the higher prevalence of long-term complications.

Changes in female cancer diagnostic billing rates over the COVID-19 period in the Ontario Health Insurance Plan

Background

The initial response to coronavirus disease 2019 (COVID-19) in Ontario included suspension of cancer screening programs and deferral of diagnostic procedures and many treatments. Although the short-term impact of these measures on female cancers is well documented, few studies have assessed the mid- to long-term impacts.

Objectives

To compare annual billing prevalence and incidence rates of female cancers during the COVID-19 period (2020-2022) to pre-COVID-19 levels (2015-2019).

Design

Retrospective analysis of aggregated claims data for female cancer diagnostic codes from the Ontario Health Insurance Plan (OHIP).

Methods

Linear regression analysis was used to fit pre-COVID-19 (2015-2019) data for each OHIP billing code and extrapolate counterfactual values for the years of 2020-2022. Excess billing rates were calculated as the difference between projected and actual rates for each year.

Results

In 2020, OHIP billing prevalence rates for cervical, breast, uterine, and ovarian cancers decreased relative to projected values for that year by -50.7/100k, -13.9/100k, -3.5/100k, and -3.8/100k, respectively. The reverse was observed in 2021 with rate increases of 47.8/100k, 59.1/100k, 2.5/100k, and 3.7/100k, respectively. In 2022, the excesses were further amplified, especially for cervical and breast cancers (111.2/100k and 78.67/100k, respectively). The net excess patient billing rate for 2020-2022 was largely positive for all female cancer types (108.3/100k, 123.7/100k, 5.2/100k, and 1.8/100k, respectively). Analysis of billing incidence rates showed similar trends.

Conclusion

The expected female cancer billing rate decreases in 2020 were followed by large increases in 2021 and 2022, resulting in a cumulative excess during the COVID-19 period. Further research is required to assess the nature of these changes.

Addressing Anastomotic Leak After Esophagectomy: Insights from a Specialized Unit

Background/Objectives: Anastomotic leakage is one of the most frightening and potentially fatal complications after esophagectomy. The collaboration between the surgical team, interventional gastroenterologists, and radiologists has the potential to improve the hospital stay, as well as morbidity and mortality. The aim of this study is to present our experience and evaluate the results of the multimodal management of anastomotic leak following esophagectomy in our unit. Methods: This is a retrospective study analyzing a single referral center's prospectively maintained database of all patients diagnosed with anastomotic leak between March 2019 and March 2025 using the definition of the Esophageal Complications Consensus Group. The treatment pathways and the patient outcomes are presented. The primary endpoint was 90-day mortality and in-hospital mortality. Results: A total of 241 esophageal resections were performed between March 2019 and March 2025. Lymphadenectomy of the mediastinum was performed in 88.4% of the patients. Cervical and intrathoracic anastomosis were performed in 143 (59.3%) and 98 (40.7%) cases, respectively. Twenty-nine patients (12%) with a mean age of 59.1 years developed anastomotic leak. Anastomotic leak occurred in 14.3% of intrathoracic anastomoses and 10.5% of cervical anastomoses. The median day of leak diagnosis was the sixth postoperative day. Leak management involved conservative strategies, wound exploration, endoscopic stent placement or vacuum therapy, drainage of effusions under radiologic guidance, and reoperation. The 90-day and in-hospital mortality rate was 3.4%. No cases of conduit necrosis or mediastinitis were reported. Endoscopic management was employed in 18 patients (62.1%) as a first- or second-line treatment, while reoperation was required in 6 patients (20.7%). The median interval from diagnosis to anastomosis healing was 21 days and the median duration of hospital stay 32 days. The management was successful in 27 patients (93.1%) except for 1 who developed tracheoesophageal fistula and 1 who died due to hemorrhagic complication of anticoagulant treatment. Conclusions: Anastomotic leak after esophagectomy is considered a complex, diversified, and morbid clinical entity. The evolving potential of multidisciplinary management encompassing surgical and interventional radiological and endoscopic treatment addresses the mortality rates and heralds a new era of minimizing morbidity.

Current applications of indocyanine green fluorescence angiography in trauma patients and its potential impact: a systematic review

OBJECTIVES

Tissue viability assessment is one of the main challenges in trauma surgery. Vitality assessment using indocyanine green fluorescence angiography (ICG-FA) may improve surgical decision-making. This systematic review gives an overview of current applications of ICG-FA in surgical treatment of traumatic injury and its effects on the incidence of postoperative complications and intraoperative decision-making.

DESIGN

Systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

DATA SOURCES

PubMed, EMBASE and MEDLINE were searched through 18 December 2023.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Primary research reports regarding indocyanine green (ICG)-fluorescence in patients with traumatic injury were included. Exclusion criteria were use of ICG for treatment of burn wounds, traumatic brain injury or reconstructive surgery, absence of an English or Dutch full-text and non-primary study design.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers performed the search and screening process according to standardised methods. Risk of bias was assessed using the Methodological Index for Non-Randomised Studies. Data were presented in text and overview tables.

RESULTS

Thirteen studies were included, of which six were case series/reports including three or fewer patients. Within the other seven studies, 301 patients received ICG-guided surgery. ICG was used for perfusion assessment in all studies. Injury types consisted of traumatic extremity and abdominal injury. All studies reported beneficial effects such as necrosis detection, determination of resection/debridement margins and reduction of debridement procedures. ICG could improve intraoperative decision-making and significantly decrease postoperative complications. No included studies reported ICG-related complications or adverse events.

CONCLUSION

The available literature regarding the use of ICG-FA in trauma surgery is limited, and comparability is low. Still, the results are promising and show a large potential of ICG-FA for better and more efficient treatment of trauma patients. Further research with larger samples and comparable conditions is thus necessary and highly recommended.

Vacuum-assisted closure or primary closure with relaparotomy on-demand in patients with secondary peritonitis: a systematic review and meta-analysis

BACKGROUND

Secondary peritonitis is a serious condition with significant morbidity and mortality. Its management requires emergency laparotomy for source control. Vacuum-assisted closure (VAC) and primary abdominal closure (PAC) are the main strategies for managing the laparostomy after source control. Despite the increasing use of VAC, concerns persist regarding its complications and long-term outcomes compared with PAC.

METHODS

This systematic review followed PRISMA 2020 and MOOSE. The Cochrane Risk of Bias (RoB 2) tool, MINORS and GRADE framework assessed study quality and evidence certainty. The protocol was registered in PROSPERO (CRD42022304724). A comprehensive search of MEDLINE, Embase, and the Cochrane Library from January 2004 to August 2024 identified studies reporting postoperative outcomes following VAC or PAC after laparotomy for secondary peritonitis. The included studies had to report at least two key outcomes: mortality, postoperative complications, incisional hernia, secondary fascial closure, and hospital or intensive care unit (ICU) length of stay.

RESULTS

Thirty-three studies including 4,520 patients were analyzed. Mortality was 31.1% in VAC and 22.2% in PAC (p = 0.327). Postoperative complications were higher with VAC (71.0% vs. 39.3%, p = 0.001). Incisional hernia rates were similar (21.3% vs. 20.8%, p = 0.958). Secondary fascial closure rate was significantly lower with VAC (58.1% vs. 85.9%, p < 0.001). VAC patients had longer ICU stays (21.1 vs. 9.7 days, p = 0.04), while hospital stay did not differ. Most studies had a high risk of bias, and GRADE assessment showed low to very low evidence certainty.

CONCLUSION

VAC therapy was associated with more postoperative complications, a lower fascial closure rate, and a longer ICU length of stay compared with PAC. Thirty-day mortality rates did not differ between the approaches. However, most of studies included were subject to serious risk of bias and a low level of certainty in evidence.

Impact of Coronavirus Disease (COVID)-19 on the Indigenous Population of Brazil: A Systematic Review

BACKGROUND

Indigenous peoples in Brazil were severely impacted by coronavirus disease (COVID)-19 pandemic, experiencing high rates of infection and mortality. Geographic isolation, limited access to healthcare, socio-economic disparities, and cultural factors, such as communal living and mistrust of state-led initiatives, heightened their vulnerability. Territorial invasions and oxygen shortages further exacerbated the crisis. Therefore, this systematic review aimed to explore the progression of COVID-19 in this population.

METHODS

A systematic review was conducted in PubMed-MEDLINE, SciELO (Scientific Electronic Library Online), and LILACS (Latin America and the Caribbean Health Sciences Literature) from the beginning of the pandemic in Brazil (2020) to March 2025. Studies addressing COVID-19 vaccination and epidemiological, social, and economic aspects among Indigenous populations in Brazil were included. Reviews and irrelevant studies were excluded. The quality of eligible studies was assessed using the Newcastle-Ottawa Scale.

RESULTS

A total of 50 relevant studies were included, grouped into thematic blocks: mortality/infection, symptoms, vaccination/testing, social impacts, and birth outcomes. Several studies highlighted that being male, of Indigenous or other racial minority background, and having comorbidities increased mortality risk. In contrast, asthma was associated with reduced mortality. Pregnant Indigenous women in rural areas had 33 times higher odds of dying than their urban counterparts. Furthermore, there is a higher likelihood of very low birth weight and inadequate prenatal care among Indigenous mothers. Vaccination reduced the risk of death, particularly after full immunization, though it did not prevent hospitalization. A cohort study of 389,753 Indigenous people showed a lower full vaccination rate (48.7%) compared to the general population (74.8%). Complete vaccination reduced the risk of death by 96% among hospitalized patients. Regarding seroprevalence, Indigenous people had a 5.4% positivity rate, much higher than other racial groups, and were 4.71 times more likely to test positive than White, Black, or Mixed Individuals. Socioeconomic disparities also correlated with increased infection risk.

CONCLUSIONS

The COVID-19 pandemic worsened health disparities among Indigenous peoples in Brazil, revealing systemic inequalities, weak public policies, and limited healthcare access. This review urges culturally sensitive, community-led responses and highlights the need for disaggregated data and equitable, inclusive health strategies.

Perioperative SARS-CoV-2 infection and postoperative complications: a single-centre retrospective cohort study in China

OBJECTIVE

To explore the association between perioperative SARS-CoV-2 infection and the postoperative complications during the breakout of the Omicron epidemic wave.

DESIGN

Observational retrospective cohort study. Multivariable logistic regression was performed to explore the association between the duration from surgery to COVID-19 diagnosis and the likelihood of postoperative complications.

SETTING

A general hospital in China.

PARTICIPANTS

7927 patients aged 18 years and older who underwent surgical treatment between 1 December 2022 and 28 February 2023.

PRIMARY OUTCOME MEASURES

The outcome was a composite of postoperative adverse events that occurred within the initial 30 postoperative days.

RESULTS

Of all patients, 420 (11.76%) experienced postoperative complications. Compared with No COVID-19, preoperative COVID-19 within 1 week (pre-1w) exhibited a high risk of postoperative complications (adjusted OR (aOR), 2.67; 95% CI 1.50 to 4.78), followed by patients with pre-2w (aOR, 2.14; 95% CI 1.20 to 3.80). For patients with postoperative COVID-19 within 1 week (post-1w), the aOR was 2.48 (95% CI 1.48 to 4.13), followed by patients with post-2w (aOR 1.95; 95% CI 1.10 to 3.45), and those with post-3w (aOR 2.25; 95% CI 1.27 to 3.98). The risks of postoperative complications decreased roughly with the increase of the time interval between the surgery date and SARS-CoV-2 infection. Stratification analyses suggested that perioperative COVID-19 increased the risk of postoperative complications in older patients, smokers, those with comorbidities or experiencing moderate or severe COVID-19 symptoms.

CONCLUSIONS

Our findings reveal a significant time-dependent relationship between perioperative COVID-19 and postoperative complications, highlighting the importance of tailored preoperative risk evaluations, enhanced postoperative surveillance, and the implementation of effective postoperative COVID-19 prevention measures.

Insights on Health Burden, Needs, and Prevention Strategies After the Flood Catastrophe in Southern Brazil

Brazil has experienced a significant increase in climate emergencies and environmental disasters. Rio Grande do Sul (RS), the southern state of the country, shows an annual rise in climate, hydrological, and meteorological disasters, underscoring its vulnerability to extreme events and the urgent need for proactive mitigation and adaptation strategies. Despite this growing concern, the literature has provided limited focus on the specific public health demands arising from these disasters, particularly regarding prevention. This debate article highlights the short-, medium-, and long-term health needs following the recent floods in RS, integrating disaster prevention science to enhance preventive actions. Floods have profound mental health and behavioral consequences, including increased rates of post-traumatic stress disorder, depression, and anxiety, particularly among displaced individuals and first responders. This analysis uses the RS case to illustrate a multi-tiered prevention approach-spanning primary, secondary, tertiary and quaternary measures-while presenting a model that could be adapted to similar vulnerable regions worldwide. By emphasizing early detection, strategic resource allocation, and evidence-based interventions, the findings highlight the importance of structured responses in minimizing health risks, bolstering community resilience, and preventing health deterioration in climate-vulnerable regions.

Prospective analysis of adiposity metrics for complicated acute colonic diverticulitis: Should WSES Classification and visceral adiposity be integrated for predictive analyses?

BACKGROUND

Colonic diverticulitis is correlated with age, body mass index (BMI), and increased visceral or subcutaneous fat. Obesity contributes to diverticulosis, diverticulitis and its complications onset, as visceral fat activates inflammatory pathways that exacerbate these conditions. The aim of this study was to evaluate the association of visceral adiposity and BMI on complications of acute colonic diverticulitis.

METHOD

A prospective cohort study was conducted on patients with acute diverticulitis admitted to the general surgery ward of a university hospital in Istanbul from September 2017 to February 2022. A total of 208 patients were classified into uncomplicated and complicated diverticulitis per the World Society of Emergency Surgery guidelines. After documenting demographic, clinical, and laboratory data, along with BMI and computed tomography measurements of visceral and subcutaneous fat areas (VFA, SFA), we conducted a statistical analysis to assess the relationships between VFA, SFA, and BMI in both groups.

RESULTS

Complicated diverticulitis group was found to have significantly lower values of BMI and VFA (p = 0.037 and p = 0.046 respectively). Similarly, BMI and VFA values of patients who underwent all interventional procedures including percutaneous drainage and surgery were found to be significantly lower than the conservative treatment group (p = 0.007, p = 0.025 respectively). V/S < 0.68 is an independent predictor in the complicated group.

CONCLUSION

Our study shows that complicated diverticulitis cases have lower BMI and visceral fat area. We suggest that increased visceral adipose tissue may serve a protective role by preventing these diverticula from developing into more complicated forms. Therefore, visceral adiposity metrics can be integrated in the predictive analyses.

TreatmENT of AnastomotiC LeakagE after colon cancer resection: the TENTACLE - Colon study

BACKGROUND

Anastomotic leakage (AL) is a common and severe complication after colon cancer resection, but studies investigating various treatment strategies and factors influencing outcomes are scarce.

OBJECTIVES

(1) To identify predictive factors associated with 90-day mortality and 90-day Clavien-Dindo grade 4-5 complications amongst patients who developed AL following colon cancer resection with subsequent development and validation of prediction models, and (2) to explore and compare the effectiveness of various treatment strategies for AL following colon cancer resection, adjusting for type of index surgery, different leak entities and patient factors.

METHODS

The TENTACLE - Colon is an international multicentre retrospective cohort study. Consecutive patients with AL after colon cancer resection operated between 1 January 2018 and 31 December 2022 from participating centres will be included. The planned sample size is 2000 patients. The primary outcome is 90-day mortality and the co-primary composite endpoint is Clavien-Dindo grade 4-5 complications. Secondary outcomes include: hospital and intensive care unit length of stay, number of radiological and surgical reinterventions within one year after resection, mortality (in-hospital, 30-day, and 1-year), the comprehensive complication index, and 1-year stoma-free survival. For objective 1, regression models will be used to identify predictors associated with 90-day mortality and grade 4-5 complications. For objective 2, comparative analyses of various treatment strategies will be performed for the specified outcomes, adjusting for patient, tumour, resection and leakage characteristics.

TRIAL REGISTRATION

This study is registered at clinicaltrials.gov (NCT06528054) since July 30th, 2024.

Effectiveness of Systemic Inflammation Response Index (SIRI) Neutrophil-Lymphocyte Ratio (NLR), Derived Neutrophil-Lymphocyte Ratio (dNLR), and Systemic Immune Inflammation Index (SII) for predicting prognosis of acute diverticulitis

There are many applications to emergency services due to acute colonic diverticulitis. It is necessary to decide whether these patients are complicated, to quickly predict their prognosis, and to decide whether medical or invasive treatment is necessary. We planned to research effectiveness NLR, NLR, SII, and SIRI values calculated using hemogram data can predict the prognosis of acute diverticulitis. We managed a retrospective scanning with patients who applied with a diagnosis of acute diverticulitis between 06/2020 and 04/2023. Demographic data (age, gender, previous surgery, comorbid diseases), tomographic Hinchey classification, location of diverticulitis, applied treatment, and obtained from blood parameters at presentation to the emergency department WBC, CRP, NLR, dNLR, SII, SIRI parameters were recorded from the electronically registered patient files. According to the Hinchey classification, those with Hinchey 0 and 1a were included in the noncomplicated group A class because they were followed up with outpatient medical follow-up. Those with Hinchey 1b,2,3,4 were included in the complicated GROUP B class. Differences in WBC, CRP, NLR, dNLR, SIRI, SII values between the complicated and noncomplicated groups were evaluated statistically. There were 286 patients with acute diverticulitis on the dates indicated. The number of patients eligible for the study was eighty-two. According to Hinchey's classification, 56 patients had noncomplicated acute diverticulitis (SAD) and 26 patients had complicated diverticulitis (CAD). These diagnoses were given based on tomography findings and clinical evaluations. The hospital stay was longer in the CAD group compared to the SAD group (p < 0.001) statistically significantly. The rate of surgical procedures and percutaneous interventions in the CADs was higher than SADs (p: 0.040) statistically significantly. WBC (white blood cell), NLR, dNLR, SIRI, SII and CRP parameters were higher in CADs than in SADs as statistically significant. Spearman's correlation analysis showed between the Hinchey classification and the NLR, dNLR, SII, SIRI, CRP, WBC parameters with high correlation as positive. Determination of values SIRI (2.42), NLR (3.35), SII (907.44) dNLR (4.63), CRP (15.25) WBC (11.16) and specificity and fractionation of these values ROC analysis was performed for this purpose. Highest AUC (area under the curve) value was found in WBC [0.807 0.703-0.910)], SIRI [0.786 (, 0.681-0.892)], SII [0.767 (0.654-0.880)], NLR [0.740 (0.624-0.854)], dNLR [0.739 (0.625-0.853)]. This study showed that there are SII, SIRI dNLR, NLR, CRP, and WBC values in patients presenting with acute diverticulitis a very high correlation with Hinchey classification in distinguishing complicated and non-complicated acute diverticulitis (p < 0.01). These data were higher in CADs than in SADs statistically significantly. The use of these data can both prevent unnecessary radiation in patients suspected of acute diverticulitis by reducing unnecessary tomography scans and can be valuable in predicting the prognosis of diverticulitis at a low cost.

The impact of different task contexts on emergency responders' trust and usage intention of artificial intelligence

Proper use of artificial intelligence (AI) can significantly enhance emergency responders' performance. However, they do not always trust or appropriately use AI. This study examined emergency responders' trust in AI and usage intention under different rescue pressures and uncertainty from the perspective of perceived capability. This study was conducted in two phases: first, questionnaire data were collected from 99 firefighters; second, semi-structured interviews were conducted with 12 participants. Results revealed that rescue pressure affected perceived AI capability, whereas uncertainty influenced perceived self-capability. Rescue pressure affected perceived AI capability, which subsequently impacted trust, and ultimately, usage intention. These findings explain the process through which rescue pressure impacts willingness to use AI. This study also explores the psychological mechanisms of trust and usage and provides valuable recommendations for designers to develop AI systems suitable for emergency responders.

The impact of the COVID-19 pandemic on emergency general surgery outcomes: a retrospective analysis of seven procedures

Current research has examined emergency general surgery (EGS) rates and COVID-19 complications for some procedures, but none have explored complications for all seven EGS procedures before and during the pandemic. Our study addresses this gap, aiming to understand how pandemic-related challenges impact patient outcomes. Utilizing data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) spanning 2018 to 2021, we conducted a retrospective cohort study with analysis of open and laparoscopic partial colectomy, enterectomy, cholecystectomy, operative management of peptic ulcer disease, adhesiolysis, appendectomy, and laparotomy. Patient outcomes, including 30-day mortality and morbidity, were assessed. The likelihood of complications in EGS has risen compared to pre-COVID levels. Specifically, there is a greater risk of morbidity in open EGS cases intra-COVID compared to laparoscopic, particularly in colectomy and appendectomy procedures. Conversely, laparoscopic procedures have seen a decrease in readmissions, notably in cases involving cholecystectomy and colectomy. The study highlights a rise in complications for EGS intra-COVID, with open procedures demonstrating higher risks than laparoscopic counterparts.
