Abstract
Antibiotics are recognized widely for their benefits when used appropriately. However, they are often used inappropriately despite the importance of responsible use within good clinical practice. Effective antibiotic treatment is an essential component of universal healthcare, and it is a global responsibility to ensure appropriate use. Currently, pharmaceutical companies have little incentive to develop new antibiotics due to scientific, regulatory, and financial barriers, further emphasizing the importance of appropriate antibiotic use. To address this issue, the Global Alliance for Infections in Surgery established an international multidisciplinary task force of 295 experts from 115 countries with different backgrounds. The task force developed a position statement called WARNING (Worldwide Antimicrobial Resistance National/International Network Group) aimed at raising awareness of antimicrobial resistance and improving antibiotic prescribing practices worldwide. The statement outlined is 10 axioms, or "golden rules," for the appropriate use of antibiotics that all healthcare workers should consistently adhere in clinical practice.

Abstract
BACKGROUND Stoma formation is a commonly performed procedure both during and following colorectal surgery. When designed correctly, stomas can dramatically improve patients' quality of life, but the reverse may occur when complications arise. Given the significant negative impact of complications following stoma formation, understanding risk factors that may be mitigated pre-operatively is important. METHOD A systematic search of publications using MEDLINE, CINAHL, and Cochrane databases was conducted in May 2022. Data was extracted and a narrative synthesis undertaken. The evidence-based librarianship (EBL) checklist assessed the methodological quality of the included studies. The systematic review includes various research designs such as randomised controlled trials (RCT), case-control studies, and observational cohort studies written in English. Reviews, conference papers, opinion papers, and those including participants < 18 years old were excluded. No restrictions on the date of publication and study setting were applied. RESULTS This review included 17 studies, conducted between 2001 and 2020. The study designs were prospective audit, prospective analysis, retrospective analysis, longitudinal analysis and multivariate analysis of self-reported questionaires/surveys. Twenty-two possible risk factors for the development of stoma complications following stoma formation were identified. These include demographical risk factors, underlying medical condition, type of surgery, elective vs emergency surgery, stoma factors, surgical factors, indications for surgery and factors which may impact healing. Furthermore, high BMI, emergency surgery, and stoma type were identified as the most frequently occurring risk factors. CONCLUSION Given the large number of risk factors identified, the implementation of a risk stratification tool may decrease the incidence and prevalence of stoma complication development. This, in turn, would decrease the associated healthcare-related costs, and negative impact on mortality, length of stay and quality of life.

Abstract
BACKGROUND Mucinous rectal cancer is associated with a higher incidence of microsatellite instability and a poorer response to neoadjuvant chemoradiotherapy compared to other subtypes of rectal adenocarcinoma. Immune checkpoint inhibitors are an emerging family of anticancer therapeutics associated with highly variable outcomes in colorectal cancer. Although the immune landscape of mucinous rectal cancer has not been fully explored, the presence of mucin is thought to act as a barrier preventing immune-cell infiltration. OBJECTIVE The aim of this study was to determine the immune properties of mucinous rectal cancer and investigate the degree of lymphocyte infiltration in this cohort. DESIGN This is a retrospective cohort study that involved multiplexed immunofluorescence staining of tumor microarrays. SETTINGS Samples originated from a single university teaching hospital. PATIENTS Our cohort included 15 cases of mucinous and 43 cases of nonmucinous rectal cancer. MAIN OUTCOME MEASURES Immune cells were classified and quantified. Immune-cell counts were compared between mucinous and nonmucinous cohorts. Immune marker expression within tumor epithelial tissue was evaluated to determine the degree of lymphocyte infiltration. RESULTS Cytotoxic ( p = 0.022) and regulatory T cells ( p = 0.010) were found to be overrepresented in the mucinous cohort compared to the nonmucinous group. Programmed cell death protein 1 expression was also found to be significantly greater in the mucinous group ( p = 0.001). CD3 ( p = 0.001) and CD8 ( p = 0.054) expressions within the tumor epithelium were also higher in the mucinous group, suggesting adequate immune infiltration despite the presence of mucin. In our analysis, microsatellite instability status was not a predictor of immune marker expression. LIMITATIONS The relatively small size of the cohort. CONCLUSIONS Mucinous rectal cancer is associated with an immune-rich tumor microenvironment, which was not associated with microsatellite instability status.

También se encontró que la expresión de PD-1 era significativamente mayor en el grupo mucinoso ( p = 0,001). La expresión de CD3 ( p = 0,001) y CD8 ( p = 0,054) dentro del epitelio tumoral también fue mayor en el grupo mucinoso, lo que sugiere una infiltración inmunitaria adecuada a pesar de la presencia de mucina. En nuestro análisis, no se encontró que el estado de inestabilidad de los microsatélites sea un predictor de la expresión del marcador inmunitario.LIMITACIONES:El tamaño relativamente pequeño de la cohorte.CONCLUSIONES:El cáncer rectal mucinoso se asocia con un microambiente tumoral rico en inmunidad, que no se asoció con el estado de inestabilidad de microsatélites.

Abstract
BACKGROUND Sarcopenia is a multifactorial loss of muscle mass that can complicate surgical outcomes and increase morbidity and mortality. Parastomal hernias can occur after any surgery requiring stoma formation and is an area of concern as a complication as it can require a second surgery or emergency surgical intervention. AIM To assess the impact of sarcopenia on parastomal hernia formation in the postoperative period. METHOD A systematic search of publications using MEDLINE, CINAHL, and Cochrane databases was conducted in June 2022. Data were extracted, and a narrative synthesis was undertaken. The Crowe Critical Appraisal Tool (CCAT) assessed the quality of the included studies. The systematic review included original research studies, prospective and retrospective designs, and human studies written in English. Reviews, conference papers, opinion papers, and those including participants < 18 years old were excluded. No restrictions on the date of publication and study setting were applied. RESULTS Nine studies met the inclusion criteria, and these were conducted between 2016 and 2021; 56% (n = 5) used a retrospective study design. The mean sample size was 242.5 participants (SD = ±358.6). No consistent or standardized way of defining sarcopenia or measuring muscle mass was seen between the studies reviewed. However, 45% (n = 4) of the studies reported a significant relationship between sarcopenia and wound healing complications, including an increased incidence of parastomal and incisional hernias. The average CCAT score was 27.56 (SD = ±4.39). CONCLUSION There is no definitive relationship between sarcopenia and hernia development; however, four studies found a significant relationship between sarcopenia and hernia formation. It must also be considered that different disease processes can cause sarcopenia either through the disease process itself, or the treatment and management. More research and consistent measurements are needed before comparable and consistent outcomes can be compiled.

Abstract
Abstract
Background
Frailty is a risk factor for in-hospital mortality, long hospital stay and functional decline at discharge. Profiling the prevalence and level of frailty within the acute hospital setting is vital to ensure evidence-based practice and service development within the construct of frailty.
Methods
All patients aged ≥65 years and admitted to a medical or surgical inpatient setting, were screened over a 12-hour period (08:00-20:00) using validated frailty and co-morbidity scales. Age and Gender Demographics, Clinical Frailty Scale (CFS), Charlson Co-morbidity Index (CHI) and admitting specialty (Medical/Surgical) were collected. The data was fully anonymised and ethical approval was granted. Descriptive statistics were used to profile the cohort and Chi-squared tests applied for comparisons.
Results
Within a sample of 413 patients, 291(70%) were ≥65yrs. Of this cohort, 202(70%) were ≥75yrs. 207(71%) utilised in-patient medical services and 121(41%) surgical services while 37(12%) used both. The mean CFS was 6 indicating moderate frailty levels and the mean CCI score was 4 denoting moderate co-morbidity. Overall: 195(67%) had moderate-severe frailty (CSF ≥6) while 218 (75%) had moderate-severe co-morbidity (CCI Mod 3-4, Severe ≥5). Associations with age >75 and frailty (p=0.001) and medical service usage and frailty (p=0.004) were established. No significant differences were observed across genders for CFS (p=0.110) and CCI (p=0.465).
Conclusion
There is a high prevalence of frailty and co-morbidity within the admitted patient cohort ≥65yrs. Overcrowding across the hospital system and higher levels of frailty and comorbidity will contribute to increased lengths of stay and the need for specialist intervention, particularly for those ≥75yrs who represented 70% of patients screened. With an increased focus on the integration of care for older adults across care transitions, there is a clear need for expansion of frailty-based services and staff training in frailty care across the hospital and community setting.

NAV3 is a genetic determinant of myocardial recovery in dilated cardiomyopathy and attenuates cardiac fibrosis. Eur Heart J 2022.

Abstract
Abstract
Background
A genome-wide association study (GWAS) assessing change in left ventricular ejection fraction (LVEF) in dilated cardiomyopathy (DCM), a surrogate marker of morbidity and mortality in heart failure (HF), had not been performed previously and could provide insight into novel biological pathways that could lead to the development of new drugs that might target myocardial recovery. The presence and extent of cardiac fibrosis in DCM is independently associated with myocardial recovery and cardiovascular mortality.
Purpose
To identify the biological relevance of genetic targets that are associated with change in LVEF in patients with DCM.
Methods
A GWAS was performed using DNA from 686 patients with recent onset DCM who were on standard HF therapy using change in LVEF at a median of 6 months after initial diagnosis. Cultured human cardiac fibroblasts (HCFs) were used as an in vitro model to study the functional and biological relevance of the gene target identified in the GWAS. Specifically, HCFs were transfected with siRNA by using the Lipofectamine™ RNAiMAX Transfection Reagent for gene knockdown (KD). RNA-seq was performed using the Illumina TruSeq protocol with expression analysis conducted with the EdgeR package. Ingenuity Pathway Analysis was used.
Results
A single-nucleotide polymorphism, rs11105445(G>A), mapping to the neuron navigator 3 (NAV3) gene (rs11105445, p=2.37E-07; beta 2.74±0.53) was associated with improvement in LVEF. We performed a phenome-wide association study using data from the UK Biobank and demonstrated that genetic variation in NAV3 was significantly associated with HF mortality (p=3.2E-28), highlighting the potential importance of this gene in HF. Using GTEx data we demonstrated that in LV tissue the minor allele A was associated with ↓NAV3 expression (p=0.03) suggesting that ↓NAV3 expression might be associated with improvement in LVEF. We demonstrated that NAV3 KD significantly ↓TGF-β1 mediated HCF transdifferentiation into myofibroblasts, ↓α-smooth muscle actin (ACTA2) and ↓collagen I (COL1A1), therefore NAV3 KD was anti-fibrotic (see Figure 1), 1a. HCFs treated by vehicle/TGF-β1 after KD of NAV3/ctrl, and ACTA2 and COL1A1 were analyzed by qPCR; 1b. Representative immunofluorescence staining for α-SMA (in green), RNA-seq after NAV3 KD followed by pathway analysis suggested that NAV3 exerted its effect by regulating cell cycle related proteins (Figure 2), 2a. Volcano plot shows significant differentially expressed genes identified by RNA-seq analysis (down-regulated in blue, up-regulated in red); 2b. NAV3 KD significantly increased expression of cell cycle related proteins, which was validated by Western blot.
Conclusions
Decreased expression of NAV3 is associated with myocardial recovery in DCM, most likely due to its anti-fibrotic effect via direct regulation of cell cycle proteins. The role of NAV3 as a novel therapeutic target in DCM needs to be explored.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
BACKGROUND Enhanced recovery programmes in laparoscopic colorectal surgery (LCS) employ combined approaches to achieve postoperative analgesia. Transversus abdominis plane (TAP) block is a locoregional anaesthetic technique that may reduce postoperative pain. AIMS To perform a systematic review and meta-analysis to compare the effectiveness of laparoscopic- versus ultrasound-guided TAP block in LCS. METHODS Databases were searched for relevant articles from inception until March 2022. All randomised controlled trials (RCTs) that compared laparoscopic (LTB) versus ultrasound-guided (UTB) TAP blocks in LCS were included. The primary outcome was narcotic consumption at 24 h postoperatively, whilst secondary outcomes included pain scores at 24 h postoperatively, operative time, postoperative nausea and vomiting (PONV) and complication rates. Random effects models were used to calculate pooled effect size estimates. RESULTS Three RCTs were included capturing 219 patients. Studies were clinically heterogenous. On random effects analysis, LTB was associated with significantly lower narcotic consumption (SMD - 0.30 mg, 95% CI = - 0.57 to - 0.03, p = 0.03) and pain scores (SMD - 0.29, 95% CI = - 0.56 to - 0.03, p = 0.03) at 24 h. However, there were no differences in operative time (SMD - 0.09 min, 95% CI = - 0.40 to 0.22, p = 0.56), PONV (OR = 0.97, 95% CI = 0.36 to 2.65, p = 0.96) or complication (OR = 1.30, 95% CI = 0.64 to 2.64, p = 0.47) rates. CONCLUSIONS LTB is associated with significantly less narcotic usage and pain at 24 h postoperatively but similar PONV, operative time and complication rates, compared to UTB. However, the data were inconsistent, and our findings require further investigation. LTB obviates the need for ultrasound devices whilst also decreasing procedure logistical complexity.

Abstract
Abstract
Background
Colon Capsule Endoscopy (CCE) has proven efficacy in a variety of gastrointestinal diseases. Few studies have assessed patient-reported outcomes and preference between colonoscopy and CCE.
Methods
Patients from our centre who had both a CCE and colonoscopy within a 12-month period were identified. We performed over-the-phone interviews focused on satisfaction, comfort, and overall preference with a 10-point Likert scale. Electronic records were reviewed; reported Modified-Gloucester-Comfort-Scale (GCS) score, sedation, bowel preparation and endoscopist grade were documented. Data was compared between procedures. A Fishers exact test was used to compare proportions and a Student t-test was used to compare means, a p < 0.05 was considered significant.
Results
In all, 40 patients were identified, 57.5% (23/40) were female and the mean age was 48 years (24–78). All patients were referred for investigation of lower gastrointestinal symptoms as part of an ongoing study [Endosc Int Open. 2021;09(06):E965–70]. There was a significance difference in mean comfort (9.2 vs 6.7, p < 0.0001, 95% CI − 3.51 to − 1.44) but not satisfaction (8.3 vs 7.7, p = 0.2, 95% CI − 1.48 to 0.33) between CCE and colonoscopy. Main cause of dissatisfaction with CCE was bowel preparation and for colonoscopy was discomfort. Age and gender were not found to be variables. The correlation between GCS and patient reported values was weak (R = − 0.28). Overall, 77.5% (31/40) of patients would prefer a CCE if they required further bowel investigation. Of these, 77.4% (24/31) preferred a CCE despite the potential need for follow-up colonoscopy.
Conclusions
CCE has a high satisfaction rating (8.3 vs 7.7) and has a higher patient reported comfort rating (9.2 vs 6.7) than colonoscopy. Studies have confirmed CCE and colonoscopy have equivalent diagnostic yields. The majority of patients in our cohort prefer CCE to colonoscopy. CCE should be considered as an alternative to colonoscopy in selected individuals.

A guide for assessing the clinical relevance of findings in small bowel capsule endoscopy: analysis of 8064 answers of international experts to an illustrated script questionnaire. Clin Res Hepatol Gastroenterol 2021; 45:101637. [PMID: 33662785 DOI: 10.1016/j.clinre.2021.101637] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2020] [Revised: 06/10/2020] [Accepted: 09/10/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND AIM Although recommended, the P-score used for assessing the pertinence / relevance of findings seen in small bowel (SB) capsule endoscopy (CE) is based on a low level of knowledge. The aim of this study was to evaluate the clinical relevance of the most frequent SBCE findings through an illustrated script questionnaire. MATERIALS AND METHODS Sixteen types of SBCE findings were illustrated four times each in three different settings (occult and overt obscure gastrointestinal bleeding and suspected Crohn's disease), and with a variable number (n = 1/n = 2-5/n ≥ 6), thus providing a questionnaire with 192 scenarios and 576 illustrated questions. Fifteen international experts were asked to rate the finding's relevance for each question as very unlikely (-2) / unlikely (-1) / doubtful (0) / likely (+1) / very likely (+2). The median score (≤-0.75, between -0.75 and 0.75, or ≥0.75) obtained for each scenario determined a low (P0), intermediate (P1) or high (P2) relevance, respectively. RESULTS 8064 answers were analyzed. Participation and completion rates were 93% and 100%, respectively. In overt or occult OGIB, resultant P2 findings were 'typical angiectasia', 'deep ulceration', 'stenosis', and'blood', whatever their numbers, and 'superficial ulcerations' when multiple. While in suspected CD, consensus P2 lesions were 'deep ulceration' and 'stenosis' whatever their numbers, and 'aphthoid erosions' and 'superficial ulcerations' when multiple. CONCLUSION This study establishes a guide for the evaluation of relevance of SBCE findings. It represents a step forward for SB-CE interpretation and is intended to be used as a tool for teaching and academic research.

Abstract
OBJECTIVE Evaluate the efficacy and quality of life associated with conservative treatment of acute uncomplicated appendicitis. SUMMARY BACKGROUND DATA Conservative management with antibiotics only has emerged as a potential treatment option for acute uncomplicated appendicitis. However the reported failure rates are highly variable and there is a paucity of data in relation to quality of life. METHODS Symptomatic patients with radiological evidence of acute, uncomplicated appendicitis were randomized to either intravenous antibiotics only or undergo appendectomy. RESULTS One hundred eighty-six patients underwent randomization. In the antibiotic-only group, 23 patients (25.3%) experienced a recurrence within 1 year following randomization. There was a significantly better EQ-VAS quality of life score in the surgery group compared with the antibiotic-only group at 3 months (94.3 vs 91.0, P < 0.001) and 12 months postintervention (94.5 vs 90.4, P < 0.001). The EQ-5D-3L quality-of-life score was significantly higher in the surgery group indicating a better quality of life (0.976 vs 0.888, P < 0.001). The accumulated 12-month sickness days was 3.6 days shorter for the antibiotics only group (5.3 vs 8.9 days; P < 0.01). The mean length of stay in both groups was not significantly different (2.3 vs 2.8 days, P = 0.13). The mean total cost in the surgery group was significantly higher than antibiotics only group (€4,816 vs €3,077, P < 0.001). CONCLUSIONS Patients with acute, uncomplicated appendicitis treated with antibiotics only experience high recurrence rates and an inferior quality of life. Surgery should remain the mainstay of treatment for this commonly encountered acute surgical condition.

Impact of the COVID-19 pandemic on management and outcomes in acute appendicitis: Should these new practices be the norm? Surgeon 2021; 19:e310-e317. [PMID: 33750630 PMCID: PMC7879062 DOI: 10.1016/j.surge.2021.01.009] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2020] [Accepted: 01/12/2021] [Indexed: 02/09/2023]
Abstract
Background In early 2020, the COVID-19 pandemic significantly altered management of surgical patients globally. International guidelines recommended that non-operative management be implemented wherever possible (e.g. in proven uncomplicated appendicitis) to reduce pressure on healthcare services and reduce risk of peri-operative viral transmission. We sought to compare our management and outcomes of appendicitis during lockdown vs a non-pandemic period. Methods All presentations to our department with a clinical diagnosis of acute appendicitis between 12/03/2020 and 30/06/2020 were compared to the same 110-day period in 2019. Quantity and severity of presentations, use of radiological investigations, rate of operative intervention and histopathological findings were variables collected for comparison. Results There was a reduction in appendicitis presentations (from 74 to 56 cases), and an increase in radiological imaging (from 70.27% to 89.29%) (P = 0.007) from 2019 to 2020. In 2019, 93.24% of patients had appendicectomy, compared to 71.42% in 2020(P < 0.001). This decrease was most pronounced in uncomplicated cases, whose operative rates dropped from 90.32% to 62.5% (P = 0.009). Post-operative histology confirmed appendicitis in 73.9% in 2019, compared to 97.5% in 2020 (P = 0.001). Normal appendiceal pathology was reported for 17 cases (24.64%) in 2019, compared to none in 2020 (P < 0.001) – a 0% negative appendicectomy rate (NAR). Discussion The 0% NAR in 2020 is due to a combination of increased CT imaging, a higher threshold to operate, and is impacted by increased disease severity due to delayed patient presentation. This study adds to growing literature promoting routine use of radiological imaging to confirm appendicitis diagnosis. As we enter a second lockdown, patients should be encouraged to avoid late presentations, and surgical departments should continue using radiological imaging more liberally in guiding appendicitis management.

Abstract
OBJECTIVES: Emergency abdominal surgery (EAS) refers to high-risk intra-abdominal surgical procedures undertaken for acute gastrointestinal pathology. The relationship between hospital or surgeon volume and mortality of patients undergoing EAS is poorly understood. This study examined this relationship at the national level. DESIGN: This is a national population-based study using a full administrative inpatient dataset (National Quality Assurance Improvement System) from publicly funded hospitals in Ireland. SETTING: 24 public hospitals providing EAS services. PARTICIPANTS AND INTERVENTIONS: Patients undergoing EAS as identified by primary procedure codes during the period 2014-2018. MAIN OUTCOME MEASURES: The main outcome measure was adjusted in-hospital mortality following EAS in publicly funded Irish hospitals. Mortality rates were adjusted for sex, age, admission source, Charlson Comorbidity Index, procedure complexity, organ system and primary diagnosis. Differences in overall, 7-day and 30-day in-hospital mortality for hospitals with low (<250), medium (250-449) and high (450+) volume and surgical teams with low (<30), medium (30-59) and high (60+) volume during the study period were also estimated. RESULTS: The study included 10 344 EAS episodes. 798 in-hospital deaths occurred, giving an overall in-hospital mortality rate of 77 per 1000 episodes. There was no statistically significant difference in adjusted mortality rate between low and high volume hospitals. Low volume surgical teams had a higher adjusted mortality rate (85.4 deaths/1000 episodes) compared with high volume teams (54.7 deaths/1000 episodes), a difference that persisted among low volume surgeons practising in high volume hospitals. CONCLUSION: Patients undergoing EAS managed by high volume surgeons have better survival outcomes. These findings contribute to the ongoing discussion regarding configuration of emergency surgery services and emphasise the need for effective clinical governance regarding observed variation in outcomes within and between institutions.

Abstract
Background Post-treatment management is essential for improving the health and quality of life of colorectal cancer (CRC) survivors. The number of cancer survivors is continually increasing, which is causing a corresponding growth in the need for effective post-treatment management programs. Current research on the topic indicates that such programs should include aspects such as physical activity and a proper diet, which would form the basis of lifestyle change among CRC survivors. Therefore, this study aimed to identify the impact of physical activity and diet on the quality of life of CRC survivors. Methods We performed a systematic literature review regarding CRC survivors. We searched the Embase, PubMed, and EBSCOhost databases, considering papers published between January 2000 and May 2017 in any language, using a combination of the following subject headings: “colorectal cancer,” “colorectal carcinoma survivor,” “survivorship plan,” “survivorship care plan,” “survivorship program,” “lifestyle,” “activities,” “exercise,” “diet program,” and “nutrition.” Results A total of 14,036 articles were identified, with 35 satisfying the eligibility criteria for the systematic review. These articles were grouped by the study questions into physical activity and diet: 24 articles were included in the physical activity group and 11 in the diet group. Conclusions The research showed that an effective survivorship program can significantly help CRC survivors maintain good health and quality of life for long periods. However, there is a lack of consensus and conclusive evidence regarding how the guidelines for such a program should be designed, in terms of both its form and content.

Abstract
INTRODUCTION Preoperative radiation combined with mesorectal excision has reduced local recurrence rates in rectal cancer. The role for neoadjuvant therapy in upper third rectal cancer remains unclear. The current study aimed to use meta-analytical techniques to compare outcomes of upper third rectal tumors relative to those of the middle and lower rectum. MATERIALS AND METHODS Meta-analysis was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases were searched for studies comparing outcomes between patients with upper third and more distal rectal cancer undergoing primary resection. Patients receiving neoadjuvant treatment were excluded. Results were reported as odds ratios (ORs) with 95% confidence intervals (95% CIs). RESULTS A total of 174 citations were reviewed; 5 studies comprising 3381 patients were included in the analysis. There was no difference in the rate of T3/4 tumors (OR, 1.303; 95% CI, 0.920-1.847; P = .137), lymph node positivity (OR, 1.004; 95% CI, 0.865-1.165; P = .961), and circumferential resection margin positivity (OR, 0.898; 95% CI, 0.556-1.450; P = .660) between upper third and more distal rectal cancers. However local recurrence (OR, 0.495; 95% CI, 0.302-0.811; P = .005) and distant recurrence (OR, 0.613; 95% CI, 0.511-0.734; P < .001) were reduced in patients with upper third rectal cancer. CONCLUSIONS These data suggest that upper third rectal cancer has reduced local and distant recurrence rates despite similarity in disease stage and margin positivity. Further studies examining effects of neoadjuvant radiation in rectal cancer should consider upper rectal tumors as a distinct entity to middle and lower rectal tumors.

Abstract
Importance Surgical site infections (SSIs) are common after laparotomy wounds and are associated with a significant economic burden. The use of negative pressure wound therapy (NPWT) has recently been broadened to closed surgical incisions. Objective To evaluate the association of prophylactic NPWT with SSI rates in closed laparotomy incisions performed for general and colorectal surgery in elective and emergency settings. Data Sources The PubMed, Embase, Cochrane Central Register of Controlled Trials, and Google Scholar databases were searched without language restrictions for relevant articles from inception until December 2017. The latest search was performed on December 31, 2017. The bibliographies of retrieved studies were further screened for potential additional studies. Study Selection Randomized clinical trials and nonrandomized studies were included. Unpublished reports were excluded, as were studies that examined NPWT (or standard nonpressure) dressings only without a comparator group. Studies that evaluated the use of NPWT in open abdominal incisions were also excluded. Disagreement was resolved by discussion, and if the question remained unsettled, the opinion of the senior author was sought. A total of 198 citations were identified, and 189 were excluded. Data Extraction and Synthesis This meta-analysis was conducted according to PRISMA guidelines. Data were independently extracted by 2 authors. A random-effects model was used for statistical analysis. Main Outcomes and Measures The primary outcome measure was SSI, and secondary outcomes included seroma and wound dehiscence rates. These outcomes were chosen before data collection. Results Nine unique studies (3 randomized trials and 2 prospective and 4 retrospective studies) capturing 1266 unique patients were included. Of these, 1187 patients with 1189 incisions were included in the final analysis (52.3% male among 7 studies reporting data on sex; mean [SD] age, 52 [15] years among 8 studies reporting data on age). Significant clinical and methodologic heterogeneity existed among studies. On random-effects analysis, NPWT was associated with a significantly lower rate of SSI compared with standard dressings (pooled odds ratio [OR], 0.25; 95% CI, 0.12-0.52; P < .001). However, no difference in rates of seroma (pooled OR, 0.38; 95% CI, 0.12-1.23; P = .11) or wound dehiscence (pooled OR, 2.03; 95% CI, 0.61-6.78; P = .25) was found. On sensitivity analysis, focusing solely on colorectal procedures, NPWT significantly reduced SSI rates (pooled OR, 0.16; 95% CI, 0.07-0.36; P < .001). Conclusions and Relevance Application of NPWT on closed laparotomy wounds in general and colorectal surgery is associated with reduced SSI rates but similar rates of seroma and wound dehiscence compared with conventional nonpressure dressings.

Abstract
Last year, the centenary of the 1916 Easter rising in Ireland was marked by a commemorative programme organised by the Irish government including both historical and cultural events. The main themes of these events were remembering the past, celebrating Irish achievements and imagining our future. Reviewing the medical literature offers an insight into a century of achievement and change in Irish medicine, captured from the unique perspective of Ireland's oldest medical journal. This manuscript examines papers published during the last 100 years of the Irish Journal of Medical Science, specifically examining the most cited paper from each year. The majority of top cited papers originate in Ireland (77%) with Trinity College Dublin the commonest institution (n = 12) and obstetrics the most common specialty (n = 9). The average number of citations per article was 20.56 (SD ± 22.36; range 1-118) and the article with most citations was 'Coagulative properties of cancers' published in 1958 by O'Meara et al. The mean number of citations for the top cited publication each year has increased over time. The journal continued to publish even amidst backgrounds of war and civil unrest and represents an important cultural artefact that deserves our ongoing support.

Hidradenitis Suppurativa and Crohn's Disease: A Case Series. IRISH MEDICAL JOURNAL 2017; 110:618. [PMID: 29169000] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/07/2023]
Abstract
Hidradenitis Suppurativa (HS) is characterized by chronic recurrent abscesses, nodules and draining sinus tracts with scar formation. Cutaneous Crohn's Disease (CD) may also present similarly. We wished to identify and describe an Irish cohort with combined HS and CD, with a view to a better recognition of clinical manifestations and understanding of the pathophysiology underlying these two overlapping conditions. Cases were identified using the HIPE Code at Tallaght Hospital from 1990-2014 and retrospective review was performed. Seven patients with both HS and CD were identified, 5(71%) female. The median age of diagnosis with both conditions was 37 years. In all cases, CD had preceded the diagnosis of HS. All patients smoked. Six had an increased BMI and 43% had additional autoimmune conditions. All patients required treatment with a TNF-alpha inhibitor for HS with 5 of 6 subjects having reduced frequency of flare ups and clinically less active HS on follow up.

Abstract
AIM To determine the prevalence of psoriasis in an IBD cohort with reference to clinical characteristics and anti-TNFα use. METHODS Patients with psoriasis and IBD were retrospectively identified from the IBD database at Tallaght Hospital from 2000 to 2015. Pertinent clinical data were obtained from patients notes including anti-TNFα exposure. Prevalence rates of genuine and reactive psoriasis were calculated and compared using Student's T -test. A P values of <0.05 was considered significant. RESULTS In total, 1384 IBD patients were identified. The overall prevalence rate of IBD and psoriasis was 2.4% ( n = 33), with 1.8% ( n = 25) in the Crohn's disease group and 0.6% ( n = 8) in the ulcerative colitis group. Within the psoriasis group, 24% ( n = 8 of 33) had reactive psoriasis. The prevalence rates of psoriasis in the non-biological and biological cohorts were similar 2.5% (25 of 981) and 2% (8 of 403), respectively. There was no significant association with reactive psoriasis and disease type. There was a trend towards higher rates of reactive psoriasis Adalimumab users, 3.6% (6 of 166) vs. 0.8% (2 of 237), OR = 4.283, P = 0.077, 95% CI 0.854-21.483 in infliximab users. In addition, in our cohort, smoking was not associated with any form of psoriasis in IBD, OR = 1.377, 95% CI 0.061-3.087, P = 0.437. CONCLUSION In our large study, the prevalence rate of reactive psoriasis was similar to the background rate of psoriasis in the overall IBD cohort (2.0 vs. 2.4%). A 2% prevalence rate represents a common adverse event that clinicians should be aware of.

Abstract
BACKGROUND AND AIMS Spontaneous intra-abdominal abscess formation is a common complication of Crohn's disease. Percutaneous drainage [PD] may avoid surgery and preserve bowel length, although there is no consensus on its efficacy as the initial treatment and the associated outcomes if unsuccessful. This study uses meta-analytical techniques to compare the outcomes of PD alone versus primary surgery for Crohn's-related intra-abdominal abscess. METHODS A comprehensive search for comparative studies examining the use of PD and surgery for spontaneous Crohn's-related intra-abdominal abscess was performed. Each study was reviewed and data extracted. Random-effects methods were used to combine data. RESULTS There were six studies including a total of 333 patients that met the inclusion criteria. Surgery was performed initially in 184 patients, PD was performed in 149. Groups were similar in demographics and abscess characteristics. There was a significantly higher risk of abscess recurrence following PD (odds ratio [OR]: 6.544, 95% confidence interval [CI]: 1.783-24.010, p: 0.005]. The pooled proportion of PD patients requiring subsequent surgery was 70.7%. There was no significant difference between approaches in post-procedural complication rate [OR: 0.657, 95% CI: 0.175-2.476, p: 0.535], ultimate permanent stoma requirement [OR: 0.557, 95% CI: 0.147-2.111, p: 0.389] or length of hospital stay [difference in means: -1.006 days, 95% CI: -28.762-26.749, p: 0.943]. CONCLUSIONS PD can avoid surgery in up to 30% of patients presenting with spontaneous Crohn's-related intra-abdominal abscesses. However, the suggested advantages over surgery in relation to complications and length of stay were not apparent. Further studies in this area are needed.

Abstract
BACKGROUND The availability of double-balloon enteroscopy (DBE) and small bowel capsule endoscopy (SBCE) in Ireland has revolutionised our approach to the diagnosis and treatment of small bowel disorders. AIMS To evaluate the use of DBE in Ireland and to compare the diagnostic yield with and without prior SBCE in order to improve the efficiency of our resources for small bowel endoscopy. METHODS A retrospective comparison study of all DBEs performed between two centres, one with SBCE available, was undertaken. Information was obtained by review of endoscopy reports, referral letters, radiology reports and charts. A review of the SBCE database was undertaken to identify patients who had undergone SBCE prior to DBE. RESULTS A total of 242 DBE procedures were carried out between both centres. SBCE was performed prior to DBE in 20 % (n = 46). The overall diagnostic yield of DBE was 47 % (n = 115). There was a statistically significant difference in diagnostic yield between the DBE only and the DBE with prior SBCE groups 44 versus 61 %, respectively, p < 0.0001. There was also a significant difference in the DBE approach, with 73 % of procedures being anterograde in centre 1 versus 56 % in centre 2. A subgroup analysis of centre 1 data revealed a negative predictive value of 100 % and a positive predictive value of 74 % for SBCE when DBE findings were considered as a gold standard. CONCLUSION SBCE as a screening tool prior to DBE is extremely valuable and increases the diagnostic yield considerably as a consequence of a high negative predictive value.

Abstract
INTRODUCTION Helicobacter pylori eradication rates using conventional triple therapies are falling, making viable second-line and rescue regimens necessary. Levofloxacin, tetracycline and rifabutin are three efficacious antibiotics for rescue therapy. AIM We aimed to assess the resistance rates for H. pylori against these antibiotics in an Irish cohort. METHODS Gastric biopsies were collected from 85 patients infected with H. pylori (mean age 46 years) in the Adelaide and Meath Hospital, Dublin in 2008 and 2009. Susceptibility to antibiotics was tested using the Etest. Clinical information was obtained from endoscopy reports and chart review. RESULTS 50.6 % of patients were females. Mean age was 47 years. Ten had prior attempts at eradication therapy with amoxicillin-clarithromycin-PPI, two had levofloxacin-based second-line therapy. 11.7 % [95 % CI (6.5-20.3 %)] (N = 10) had strains resistant to levofloxacin. There were no strains resistant to rifabutin or tetracycline. Levofloxacin resistance in the under 45 age group was 2.6 % (1/38) compared to 19.1 % (9/47) of above 45 age group (p = 0.02). DISCUSSION The levofloxacin rates illustrated in this study are relatively low by European standards and in line with other studies from the United Kingdom and Germany, with younger patients having very low levels of resistance. Levofloxacin, tetracycline and rifabutin are all valid options for H. pylori eradication in Irish patients but the importance of compliance cannot be underestimated.

Abstract
We describe an ovarian borderline tumour that presented as an acute deterioration in an incisional hernia secondary to intraperitoneal mucin accumulation. The differential diagnosis associated with hernial sac contents and options for opportunistic diagnosis are discussed. This case raises awareness of potential serious diagnoses that may be overlooked during emergent hernia repair.

Abstract
AIM The assessment of procedural colonoscopy skills is important and topical. The aim of this study was to develop and validate a competency-based colonoscopy assessment form that would be easy to use, suitable for the assessment of junior and senior endoscopists and potentially a useful instrument to detect differences in performance standards following different training interventions. METHOD A standardized assessment form was developed incorporating a checklist with dichotomous yes/no responses and a global assessment section incorporating several different elements. This form was used prospectively to evaluate colonoscopy cases during the period of the study in several university teaching hospitals. Results were analysed using ANOVA with Bonferroni corrections for post hoc analysis. RESULTS Eighty-one procedures were assessed, performed by eight consultant and 19 trainee endoscopists. There were no serious errors. When divided into three groups based on previous experience (novice, intermediate and expert) the assessment form demonstrated statistically significant differences between all three groups (P<0.05). When separate elements were taken into account, the global assessment section was a better discriminator of skill level than the checklist. CONCLUSION This form is a valid, easy-to-use assessment method. We intend to use it to assess the value of simulator training in trainee endoscopists. It also has the potential to be a useful training tool when feedback is given to the trainee.

Abstract
OBJECTIVE Key to the clinical management of colorectal cancer is identifying tools which aid in assessing patient prognosis and determining more effective and personalised treatment strategies. We evaluated whether an experimental systems biology strategy which analyses the susceptibility of cancer cells to undergo caspase activation can be exploited to predict patient responses to 5-fluorouracil-based chemotherapy and to case-specifically identify potential alternative targeted treatments to reactivate apoptosis. DESIGN We quantified five essential apoptosis-regulating proteins (Pro-Caspases 3 and 9, APAF-1, SMAC and XIAP) in samples of Stage II (n = 13) and III (n=17) tumour and normal colonic (n = 8) tissue using absolute quantitative immunoblotting and employed systems simulations of apoptosis signalling to predict the susceptibility of tumour cells to execute apoptosis. Additional systems analyses assessed the efficacy of novel apoptosis-inducing therapeutics such as XIAP antagonists, proteasome inhibitors and Pro-Caspase-3-activating compounds in restoring apoptosis execution in apoptosis-incompetent tumours. RESULTS Comparisons of caspase activity profiles demonstrated that the likelihood of colorectal tumours to undergo apoptosis decreases with advancing disease stage. Systems-level analysis correctly predicted positive or negative outcome in 85% (p=0.004) of colorectal cancer patients receiving 5-fluorouracil based chemotherapy and significantly outperformed common uni- and multi-variate statistical approaches. Modelling of individual patient responses to novel apoptosis-inducing therapeutics revealed markedly different inter-individual responses. CONCLUSIONS Our study represents the first proof-of-concept example demonstrating the significant clinical potential of systems biology-based approaches for predicting patient outcome and responsiveness to novel targeted treatment paradigms.

Abstract
BACKGROUND In Ireland, colorectal cancer (CRC) is the second most frequently diagnosed cancer in men, after prostate cancer, and the second most frequently diagnosed cancer in women, after breast cancer. By 2020, the number of new cases diagnosed annually in Ireland is projected to have increased by 79% in men and 56% in women. Organised screening for CRC is already underway or is in the process of being rolled out in several European countries, either at a regional or national level. The Adelaide and Meath Hospital/ Trinity College Dublin Colorectal Cancer Screening Programme (TTC-CRC-SP) is Ireland's first pilot population based bowel screening programme. METHOD Based on a biennial test model the pilot aimed to assess the accuracy of FIT and to evaluate the whole programme based on established international key performance indices. RESULTS To date 9,993 individuals aged 50-74 years have been invited to participate in the TTC-CRC-SP with over 5,000 FIT's analysed. Overall uptake was 51% and FIT positivity was 10%. The programme has undertaken over 400 screening colonoscopies and detected 154 precancerous adenomas and 38 cancerous lesions. CONCLUSIONS The first round of The Adelaide and Meath Hospital Tallaght/Trinity College Dublin Colorectal Cancer Screening Programme has been highly successful and confirmed that there is an advantage for FIT based two stage bowel cancer screening programmes.
