Full title: "Hopes, worries and expectations" experiences of pregnancy with inflammatory bowel disease: An interpretative phenomenological analysis study.

Background and Aims: Inflammatory Bowel Disease (IBD) affects many women of childbearing age. High levels of voluntary childlessness and high levels of pregnancy-related fears have been reported amongst these patients in several quantitative studies. We investigated the lived experiences of pregnant patients to better understand decision-making processes around family planning. Methods: Nine participants between 7 and 34 weeks pregnant (6 Crohn's Disease/3 Ulcerative Colitis), with an age range of 22-39 were recruited prospectively from three United Kingdom hospitals. Semi-structured interviews were conducted, and audio recorded. Interpretative phenomenological analysis was used to interpret the data. Results: Two main themes emerged: 1) IBD is perceived as a threat to family planning; and 2) healthcare professional advice, support, and reassurance was important. IBD was viewed as a potential threat to fertility and reproductive health. Consequently, women's lived experience of pregnancy is shaped by anxiety and pregnancy-related worries for mother and baby. Mothers actively sought out expert medical assurances to alleviate some of the perceived fears. Conclusion: Previous research has repeatedly found that women with IBD exhibit high levels of pregnancy-related worries and anxieties. Our findings find that high levels of anxiety are due to patients' perceptions that IBD is a threat to their reproductive health and their offspring. Women relied on a medicalized discourse to understand their IBD experiences during pregnancy and actively sought biomedical resources for assistance before and during pregnancy. Consultants should be aware that when dealing with pregnant patients, some women may experience anxiety and require extra support.

Planning to conceive within a year is associated with better pregnancy-specific disease-related patient knowledge and better medication adherence in women of childbearing age with inflammatory bowel disease.

Background: Adherence to inflammatory bowel disease (IBD) medication is crucial to maintain remission, especially during pregnancy. Objective: To examine the influence of family planning and pregnancy-related patient knowledge regarding IBD and pregnancy on adherence. Design: Cross-sectional survey study. Methods: We surveyed female patients with IBD aged 18-35 years, who at recruitment to the UK IBD BioResource had not had children. We elicited disease and treatment history, demographics and family planning status via an online questionnaire. Patient knowledge as assessed by the validated Crohn's and Colitis Pregnancy Knowledge Score (CCPKnow) and adherence by visual analogue scale (VAS). Results: In 326 responders (13.8% response rate), good adherence (VAS ⩾ 80) was found in only 38.35%. Disease- and treatment-related factors were not significantly associated with good adherence, except for methotrexate (70.0% adherent of 10 exposed patients versus 37.2% non-exposed; p = 0.036). Patients planning pregnancy for the next year were more often adherent (59.0% versus 35.5%; p = 0.019) and knowledgeable (median CCPKnow 8 versus 7; p = 0.035) compared to those in other family planning categories. Pregnancy-related patient knowledge was significantly associated with adherence (Pearson correlation 0.141; p = 0.015). Adherent patients had significantly higher CCPKnow scores than non-adherent patients (median 8 versus 6; p = 0.009). On binary regression analysis, only planning to conceive within 12 months was independently associated with better adherence (p = 0.016), but not methotrexate exposure (p = 0.076) and CCPKnow (p = 0.056). Conclusions: In a cohort of women of childbearing age with IBD overall medication, adherence was low. Planning to conceive within the next year was associated with better adherence and greater patient knowledge.

Factors Associated with Family Planning Status and Voluntary Childlessness in Women of Childbearing Age with Inflammatory Bowel Diseases.

BACKGROUND: Women with Inflammatory Bowel Diseases (IBD) have fewer children and stay childless more often. The decision-making process around family planning choices remains incompletely understood. METHODS: We examined family status in women who at recruitment to the UK IBD Bioresource had not had children yet via an electronic survey. The primary outcome was the proportion of women with voluntary childlessness. Secondary outcomes were factors associated with family planning status. RESULTS: Of 326 responders, 10.7% had either given birth, were currently pregnant or were currently trying to conceive; 12.6% were planning to conceive within 12 months; 54.4% were contemplating conception in the distant future (vague plans); and 22.3% were voluntarily childless. Factors associated with family planning status fell into three areas: general background (age, household income, perceived support to raise a child), relationship status (sexual orientation, being single, not cohabiting, perception of being 'in the right relationship to raise a child', perception of a good sex life) and the expression of having a child as a goal in life. On binary logistics regression analysis with voluntary childlessness versus vague family plans as the outcomes of choice, having a household income of <£30,000 (p = 0.046), not seeing a child as a life goal (p < 0.0001) and identifying as lesbian or bisexual (p = 0.047) were independent predictors of voluntary childlessness. CONCLUSIONS: Clinicians should consider sexual orientation, income, younger age, current relationship and lack of expression of having a child as a life goal as important factors for family planning when providing care. Pre-pregnancy advice should be made widely available for women with IBD.

The analysis of gut microbiota in patients with bile acid diarrhoea treated with colesevelam.

Introduction: Bile acid diarrhoea (BAD) is a common disorder that results from an increased loss of primary bile acids and can result in a change in microbiome. The aims of this study were to characterise the microbiome in different cohorts of patients with BAD and to determine if treatment with a bile acid sequestrant, colesevelam, can alter the microbiome and improve microbial diversity. Materials and methods: Patients with symptoms of diarrhoea underwent 75-selenium homocholic acid (75SeHCAT) testing and were categorised into four cohorts: idiopathic BAD, post-cholecystectomy BAD, post-operative Crohn's disease BAD and 75SeHCAT negative control group. Patients with a positive 75SeHCAT (<15%) were given a trial of treatment with colesevelam. Stool samples were collected pre-treatment, 4-weeks, 8-weeks and 6-12 months post-treatment. Faecal 16S ribosomal RNA gene analysis was undertaken. Results: A total of 257 samples were analysed from 134 patients. α-diversity was significantly reduced in patients with BAD and more specifically, in the idiopathic BAD cohort and in patients with severe disease (SeHCAT <5%); p < 0.05. Colesevelam did not alter bacterial α/ß-diversity but patients who clinically responded to treatment had a significantly greater abundance of Fusobacteria and Ruminococcus, both of which aid in the conversion of primary to secondary bile acids. Conclusion: This is the first study to examine treatment effects on the microbiome in BAD, which demonstrated a possible association with colesevelam on the microbiome through bile acid modulation in clinical responders. Larger studies are now needed to establish a causal relationship with colesevelam and the inter-crosstalk between bile acids and the microbiome.

Sentinel lymph node biopsy in endometrial cancer: The new norm - A multicentre, international experience.

OBJECTIVES: The landscape of early-stage endometrial cancer treatment has changed dramatically over the last decade. The aim of this study is to provide a real-world view of the impact sentinel lymph node (SLN) biopsy has had on both clinical practice and patient outcomes. We describe detection and recurrence rates, as well as our experience in managing low volume lymph node disease. METHODS: We conducted an international, multicenter retrospective cohort study of 1012 patients with apparent early-stage endometrial cancer. Eligible patients underwent primary surgical staging and SLN biopsy in one of three large academic tertiary cancer centers in Canada or the Republic of Korea between 2015 and 2019. Demographic, surgical, clinicopathologic and recurrence data were collected through chart review. RESULTS: A total of 1012 patients were included. Overall SLN detection rate for all tracer types was 94.1% and recurrence rate was 5.3%. Higher FIGO stage (III vs. I/II) was associated with failed bilateral mapping (OR 2.27, 95%CI 1.14-4.52). We identified seven patients with micrometastases and 12 with isolated tumor cells, of which only one patient with micrometastases recurred at 17 months. Recurrence rates based on risk groups were 2.1%, 5.3%, 8.1%, and 9.9% for low, intermediate, high-intermediate, and high risk, respectively. CONCLUSION: SLN biopsy is safe and feasible. Detection rates are high, regardless of which tracer type is used and recurrence rates are low, especially in low and intermediate risk disease. Patients with low volume metastases appear to have low risk of recurrence, but replication of our findings by large prospective studies are needed to elucidate their clinical importance.

Women in gastroenterology: the UK trainee experience.

Introduction: Compared with other medical specialties, there are lower numbers of female trainees and lower rates of flexible working in gastroenterology. This study aims to examine the experience of male and female trainees to understand specialty demographics and the experience of training. Methods: Gastroenterology training data were obtained from the British Society of Gastroenterology (BSG) trainee surveys from 2014, 2018 and 2020, and from the Royal College of Physicians Medical Workforce unit between 2011 and 2019. Data on endoscopy measures from 2011 to 2021 were obtained from the Joint Advisory Group (JAG) on gastrointestinal endoscopy, including the JAG Endoscopy training system and the National Endoscopy Database. Data were segregated and compared by gender. Results: The percentage of female gastroenterology trainees remains at around 40%, largely unchanged over the previous decade. From the BSG trainee survey, 29.5% of women have flexible working patterns compared with 2.6% of men (p<0.001), which is lower than other medical specialties. Less than half of female trainees felt confident about their job prospects once they qualify. A greater proportion of male than female trainees achieved provisional colonoscopy certification during training (55% vs 45%, p=0.005) and female trainees took longer to certify than male trainees (63 months vs 56 months, p=0.004). The total length of training time from primary medical qualification to consultancy was the same for men and women. Conclusion: Changes must be addressed from a national and institutional level to address equitable access to national training programmes and equality of outcome for male and female trainees.

Improving 30-day mortality after PEG tube placement in England from 2007 to 2019: a retrospective national cohort analysis of 87,862 patients.

BACKGROUND AND AIMS: PEG has been associated with poor case selection and high mortality. We examined indications, 30-day mortality, and 7-day adverse events in a national cohort undergoing PEG tube insertion. METHODS: Adult patients undergoing their first PEG tube insertion from 2007 to 2019 were identified in the Hospital Episode Statistics database. Indications and adverse events were identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision codes. Multivariable logistic regression modeling examined factors associated with mortality. RESULTS: Of 87,682 patients identified, 58% were men and median age was 69 years (interquartile range, 57-79). The number of patients with dementia or stroke as the indication for PEG fell from 2007 to 2019 (dementia, from 147 to 28 [P < .001]; stroke, from 2851 to 1781 [P < .001]). The median interval from stroke admission to PEG tube insertion increased from 21 (interquartile range, 12-36) to 28 (interquartile range, 13-45) days (P < .001). Aspiration pneumonia within 7 days of PEG fell from 10.2% to 8.6% (P = .04). Thirty-day mortality fell from 13.2% to 5.3% (P < .001), with associated factors of increasing age (≥82 years quintile odds ratio [OR], 4.44; 95% confidence interval [CI], 4.01-4.92), PEG tube insertion during emergency admission (OR, 2.10; 95% CI, 1.97-2.25), Charlson comorbidity score ≥5 (OR, 1.67; 95% CI, 1.53-1.82), and dementia (OR, 1.46; 95% CI, 1.26-1.71). Female sex (OR, .81; 95% CI, .77-.85), least-deprived quintile (OR, .88; 95% CI, .81-.95), and more recent years of PEG tube insertion (2019; OR, .44; 95% CI, .39-.51) were negatively associated with mortality. CONCLUSIONS: Thirty-day mortality after PEG tube insertion has fallen 60% over 13 years. Dementia or stroke as an indication for PEG fell, and the time interval from stroke to PEG tube insertion increased. These findings may be attributable to improved patient selection and timing for PEG tube insertion.

The impact of treatment with bile acid sequestrants on quality of life in patients with bile acid diarrhoea.

BACKGROUND: Bile acid diarrhoea (BAD) can be severely debilitating and negatively affect patients' quality of life (QoL). We carried out a multi-centre prospective study exploring QoL outcomes in patients with BAD after treatment with colesevelam. METHODS: Patients with or without a positive 23-seleno-25-homotaurocholic acid (SeHCAT) scan were recruited and categorised into four groups: SeHCAT negative control group (CG), idiopathic BAD, post-cholecystectomy (PC) and post-terminal ileal resection for Crohn's disease (CD). Patients with a positive SeHCAT were treated with colesevelam and dosing was titrated to symptomatic response. Patients were reviewed at 4- and 8-weekly intervals and QoL was evaluated by EQ-5D-3L, SF-36, IBDQ-32 at each visit (where relevant). Patients with a negative SeHCAT (CG cohort) completed one set of questionnaires before being discharged from the study. RESULTS: 47 patients (BAD = 24, PC = 12, CD = 11) completed paired QoL questionnaires before and after treatment and 30 CG patients completed a baseline questionnaire. There was a significant improvement in IBDQ-32 mean scores before and after treatment in CD patients [134.6 (95%CI 112.5-156.6) and 158.4 (136.1-180.6), respectively (p = 0.007). Following treatment, BAD patients had significantly improved mean SF-36 scores in the "Role limitation due to physical health" dimension (p = 0.02) and in the overall mental component summary (p = 0.03). Prior to starting treatment, BAD patients had the lowest scores in the 'activity' dimension of the EQ-5D-3L (p = 0.04), which improved significantly after treatment (p = 0.002). Overall, the BAD and CD cohort showed improved mean scores with treatment in all components of the SF-36 and EQ-5D-3L, while the PC cohort showed a general decline in mean scores after treatment. 55% of patients clinically responded to treatment of which 41.7%, 58.3% and 81.8% responded from the BAD, PC and CD groups respectively. Correlations between those deemed as responders with improvements on the SF-36 and EQ-5D dimensions were not statistically significant. CONCLUSION: Our results demonstrate improved QoL in the BAD and CD cohort with treatment. Further larger studies are recommended specifically investigating the PC cohort and whether patients may improve with newer treatments such as FXR agonists. Trial registration Ethical approval REC Ref: 16/LO/1325.

Improving the Rate of Same-day Discharge in Gynecologic Oncology Patients with Endometrial Cancer undergoing Minimally Invasive Robotic Surgery: A Quality Improvement Initiative.

STUDY OBJECTIVE/SETTING/PATIENTS: Same-day discharge (SDD) in patients with endometrial cancer undergoing minimally invasive surgery (MIS) is safe and feasible, with multiple patient and healthcare system benefits. Despite this, our local rate of SDD was only 29.4%. Several studies have suggested methods to improve rates of SDD but few have evaluated the application of such methods. The objectives of our quality improvement (QI) initiative were 2-fold: (1) to increase the rate of SDD in eligible patients with endometrial cancer undergoing MIS to 70% and (2) to evaluate the implementation of methods to improve rates of SDD. DESIGN/INTERVENTIONS/MEASUREMENTS: At our center, QI diagnostics were conducted, and root causes were identified. Four interventions were introduced: (1) setting SDD as the default discharge plan, (2) ensuring that a physician order for discharge was on the chart, (3) removing the Foley catheter in the operating room, and (4) introducing pre- and postoperative patient education documents. A time-series design was used; rate of SDD was tracked using baseline data and continuous post-intervention monitoring. Process measures (for each intervention) and balancing measures were defined and tracked. MAIN RESULTS: At the conclusion of our QI initiative, the average rate of SDD was 78.3%-exceeding our aim of 70%. This was achieved without compromising patient satisfaction (98.2%) or significantly impacting rates of readmission or presentations to the emergency department. CONCLUSIONS: Our initiative demonstrated the application of simple interventions that resulted in a substantial increase in our rate of SDD in the population of interest, without causing negative impacts on the defined balancing measures. These interventions were nonspecific to gynecologic oncology and could easily be applied across other surgical disciplines.

Energy Metabolism in Gynecological Cancers: A Scoping Review.

Determining energy requirements is vital for optimizing nutrition interventions in pro-catabolic conditions such as cancer. Gynecological cancer encompasses the most common malignancies in women, yet there is a paucity of research on its metabolic implications. The aim of this review was to explore the literature related to energy metabolism in gynecological cancers. We were particularly interested in exploring the prevalence of energy metabolism abnormalities, methodological approaches used to assess energy metabolism, and clinical implications of inaccurately estimating energy needs. A search strategy was conducted from inception to 27 July 2021. Studies investigating energy metabolism using accurate techniques in adults with any stage of gynecological cancer and the type of treatment were considered. Of the 874 articles screened for eligibility, five studies were included. The definition of energy metabolism abnormalities varied among studies. Considering this limitation, four of the five studies reported hypermetabolism. One of these studies found that hypermetabolism was more prevalent in ovarian compared to cervical cancer. Of the included studies, one reported normometabolism at the group level; individual-level values were not reported. One of the studies reported hypermetabolism pre- and post-treatment, but normometabolism when re-assessed two years post-treatment. No studies explored clinical implications of inaccurately estimating energy needs. Overall, commonly used equations may not accurately predict energy expenditure in gynecological cancers, which can profoundly impact nutritional assessment and intervention.

Variability in the Pre-Analytical Stages Influences Microbiome Laboratory Analyses.

Introduction: There are numerous confounding variables in the pre-analytical steps in the analysis of gut microbial composition that affect data consistency and reproducibility. This study compared two DNA extraction methods from the same faecal samples to analyse differences in microbial composition. Methods: DNA was extracted from 20 faecal samples using either (A) chemical/enzymatic heat lysis (lysis buffer, proteinase K, 95 °C + 70 °C) or (B) mechanical and chemical/enzymatic heat lysis (bead-beating, lysis buffer, proteinase K, 65 °C). Gut microbiota was mapped through the 16S rRNA gene (V3−V9) using a set of pre-selected DNA probes targeting >300 bacteria on different taxonomic levels. Apart from the pre-analytical DNA extraction technique, all other parameters including microbial analysis remained the same. Bacterial abundance and deviations in the microbiome were compared between the two methods. Results: Significant variation in bacterial abundance was seen between the different DNA extraction techniques, with a higher yield of species noted in the combined mechanical and heat lysis technique (B). The five predominant bacteria seen in both (A) and (B) were Bacteroidota spp. and Prevotella spp. (p = NS), followed by Bacillota (p = 0.005), Lachhnospiraceae (p = 0.0001), Veillonella spp. (p < 0.0001) and Clostridioides (p < 0.0001). Conclusion: As microbial testing becomes more easily and commercially accessible, a unified international consensus for optimal sampling and DNA isolation procedures must be implemented for robustness and reproducibility of the results.

A single faecal bile acid stool test demonstrates potential efficacy in replacing SeHCAT testing for bile acid diarrhoea in selected patients.

This study examines the validity of measuring faecal bile acids (FBA) in a single stool sample as a diagnostic tool for bile acid diarrhoea (BAD) by direct comparison to the 75selenium-homotaurocholic acid (SeHCAT) scan. A prospective observational study was undertaken. Patients with chronic diarrhoea (> 6 weeks) being investigated for potential BAD with SeHCAT scan provided stool samples for measurement of FBA, using an enzyme-linked immunosorbent assay. Patients were characterised into four groups: SeHCAT negative control group, post-cholecystectomy, idiopathic BAD and post-operative terminal ileal resected Crohn's disease. Stool samples were collected at baseline and 8-weeks post treatment to determine whether FBA measurement could be used to monitor therapeutic response. 113 patients had a stool sample to directly compare with their SeHCAT result. FBA concentrations (µmol/g) and interquartile ranges in patients in the control group (2.8; 1.6-4.2), BAD (3.6; 1.9-7.2) and post-cholecystectomy cohort 3.8 (2.3-6.8) were similar, but all were significantly lower (p < 0.001) compared to the Crohn's disease cohort (11.8; 10.1-16.2). FBA concentrations in patients with SeHCAT retention of < 15% (4.95; 2.6-10.5) and < 5% (9.9; 4.8-15.4) were significantly higher than those with a SeHCAT retention > 15% (2.6; 1.6-4.2); (p < 0.001 and p < 0.0001, respectively). The sensitivity and specificity using FBA cut-off of 1.6 µmol/g (using ≤ 15% SeHCAT retention as diagnostic of BAD) were 90% and 25% respectively. A single random stool sample may have potential use in diagnosing severe BAD or BAD in Crohn's patients. Larger studies are now needed to confirm the potential efficacy of this test to accurately diagnose BAD in the absence of SeHCAT testing.

Bile Acids and the Microbiome: Making Sense of This Dynamic Relationship in Their Role and Management in Crohn's Disease.

Background: Bile acids help maintain the physiological balance of the gut microbiome and the integrity of the intestinal epithelial barrier. Similarly, intestinal bacteria play a major role in bile acid metabolism as they are involved in crucial biotransformation steps in the enterohepatic circulation pathway. Understanding the relationship between bile acid signalling and the gut microbiome in Crohn's disease can help target new and innovative treatment strategies. Aims: This review summarises the relationship between bile acids and the microbiome in Crohn's disease and discusses potential novel therapeutic options. Methods: We performed a literature review on bile acid signalling, its effect on the gut microbiome, and therapeutic applications in Crohn's disease. Results: Current research suggests that there is a strong interplay between the dysregulated microbiota, bile acid metabolism, and the mucosal immune system that can result in a changed immunological function, triggering the inflammatory response in Crohn's disease. Recent studies have demonstrated an association with altering the enterohepatic circulation and activating the farnesoid X receptor signalling pathway with the use of probiotics and faecal microbial transplantation, respectively. Bile acid sequestrants have been shown to have anti-inflammatory, cytoprotective, and anti-apoptotic properties with the potential to alter the intestinal microbial composition, suggesting a possible role in inducing and maintaining Crohn's disease. Conclusions: Active Crohn's disease has been correlated with changes in bacterial concentrations, which may be associated with changes in bile acid modification. Further research should focus on targeting these areas for future therapeutic options.

Insight from patients and healthcare professionals on the implementation of virtual clinics in patients with inflammatory bowel disease.

Introduction: During COVID-19, the management of outpatient inflammatory bowel disease (IBD) changed from face-to-face (F2F) to telephone and video consultations across the UK. We surveyed patients with IBD and IBD healthcare professionals (HCPs) to evaluate the impact of this abrupt transition on patient and HCP satisfaction outcomes, including the barriers and enablers of this service. Methods: Patient satisfaction surveys were sent to patients who had a telephone consultation from May to July 2020. A second survey was sent to IBD HCPs across the UK. Questions from both surveys consisted of a mixture of multiple-choice options, ranking answers as well as short-answer questions. Results: 210 patients and 114 HCPs completed the survey. During COVID-19, there was a significantly greater use of telephone, video or a mixture of consultation. F2F consultations were consistently preferred by patients, with 50% of patients indicating they did not want the option of for video consultations. Patients were more likely to prefer a telephone consultation if they were stable and needed routine review. Significantly fewer HCPs (5.3%) intend to use F2F consultations alone, preferring the use of telephone (20.2%) or combinations of telephone/F2F (22.8%), telephone/video (4.4%) or combination of all three consultation types (34.2%). 63% indicated they intend to incorporate video consultations in the future. Conclusion: Telephone and video consultations need to be balanced proportionately with F2F clinics to achieve both patient and HCP satisfaction. Further research needs to be done to explore the use of video medicine in patients with IBD.

UK Joint Advisory Group consensus statements for training and certification in endoscopic retrograde cholangiopancreatography.

Background and study aims Despite the high-risk nature of endoscopic retrograde cholangiopancreatography (ERCP), a robust and standardized credentialing process to ensure competency before independent practice is lacking worldwide. On behalf of the Joint Advisory Group (JAG), we aimed to develop evidence-based recommendations to form the framework of ERCP training and certification in the UK. Methods Under the oversight of the JAG, a modified Delphi process was conducted with stakeholder representation from the British Society of Gastroenterology, Association of Upper Gastrointestinal Surgeons, trainees and trainers. Recommendations on ERCP training and certification were formulated after formal literature review and appraised using the GRADE tool. These were subjected to electronic voting to achieve consensus. Accepted statements were peer-reviewed by JAG and relevant Specialist Advisory Committees before incorporation into the ERCP certification pathway. Results In total, 27 recommendation statements were generated for the following domains: definition of competence (9 statements), acquisition of competence (8 statements), assessment of competence (6 statements) and post-certification support (4 statements). The consensus process led to the following criteria for ERCP certification: 1) performing ≥ 300 hands-on procedures; 2) attending a JAG-accredited ERCP skills course; 3) in modified Schutz 1-2 procedures: achieving native papilla cannulation rate ≥80%, complete bile duct clearance ≥ 70 %, successful stenting of distal biliary strictures ≥ 75 %, physically unassisted in ≥ 80 % of cases; 4) 30-day post-ERCP pancreatitis rates ≤5 %; and 5) satisfactory performance in formative and summative direct observation of procedural skills (DOPS) assessments. Conclusions JAG certification in ERCP has been developed following evidence-based consensus to quality assure training and to ultimately improve future standards of ERCP practice.

A prospective comparison of costs between robotics, laparoscopy, and laparotomy in endometrial cancer among women with Class III obesity or higher.

BACKGROUND AND OBJECTIVES: To compare the immediate operating room (OR), inpatient, and overall costs between three surgical modalities among women with endometrial cancer (EC) and Class III obesity or higher. METHODS: A multicentre prospective observational study examined outcomes of women, with early stage EC, treated surgically. Resource use was collected for OR costs including OR time, equipment, and inpatient costs. Median OR, inpatient, and overall costs across surgical modalities were analyzed using an Independent-Samples Kruskal-Wallis Test among patients with BMI ≥ 40. RESULTS: Out of 520 women, 103 had a BMI ≥ 40. Among women with BMI ≥ 40: median OR costs were $4197.02 for laparotomy, $5524.63 for non-robotic assisted laparoscopy, and $7225.16 for robotic-assisted laparoscopy (p < 0.001) and median inpatient costs were $5584.28 for laparotomy, $3042.07 for non-robotic assisted laparoscopy, and $1794.51 for robotic-assisted laparoscopy (p < 0.001). There were no statistically significant differences in the median overall costs: $10 291.50 for laparotomy, $8412.63 for non-robotic assisted laparoscopy, and $9002.48 for robotic-assisted laparoscopy (p = 0.185). CONCLUSION: There was no difference in overall costs between the three surgical modalities in patient with BMI ≥ 40. Given the similar costs, any form of minimally invasive surgery should be promoted in this population.

Differences in the On- and Off-Tumor Microbiota between Right- and Left-Sided Colorectal Cancer.

This study aims to determine differences in the on- and off-tumor microbiota between patients with right- and left-sided colorectal cancer. Microbiome profiling of tumor and tumor-adjacent biopsies from patients with right-sided (n = 17) and left-sided (n = 7) colorectal adenocarcinoma was performed using 16S ribosomal RNA sequencing. Off-tumor alpha and beta diversity were significantly different between right- and left-sided colorectal cancer patients. However, no differences in on-tumor diversity were observed between tumor locations. Comparing the off-tumor microbiota showed the right colon to be enriched with species of the Lachnoclostridium, Selenomonas, and Ruminococcus genera. Whereas the left colon is enriched with Epsilonbacteraeota phylum, Campylobacteria class, and Pasteurellales and Campylobacterales orders, in contrast, the on-tumor microbiota showed relatively fewer differences in bacterial taxonomy between tumor sites, with left tumors being enriched with Methylophilaceae and Vadin BE97 families and Alloprevotella, Intestinibacter, Romboutsia, and Ruminococcus 2 genera. Patients with left-sided colorectal cancer had large taxonomic differences between their paired on- and off-tumor microbiota, while patients with right-sided colorectal cancer showed relatively fewer taxonomic differences. Collectively, this suggests that the right and left colon show distinctive bacterial populations; however, the presence of a colonic tumor leads to a more consistent microbiota between locations.

The Prevalence of Anaemia in a District General Hospital in the United Kingdom.

Aim Investigating the prevalence of hospital-acquired anaemia in a United Kingdom (UK) secondary care setting to describe the level of appropriate management prior to discharge back to primary care. Design and settings An observational study of 13 medical and surgical wards in a UK district general hospital. Method Single-day examination of notes, blood results and drug charts, with a 30-day follow up, using pre-set definitions of anaemia and exclusion criteria. Results Two hundred and sixty-seven patients were included. Of them, 52% were anaemic on admission, 62.2% were anaemic on the study day, 16% had hospital-acquired anaemia and 49%-82% had no biochemical indices checked during the admission or in the last 12 months. Also, 53% of anaemic patients are being discharged without appropriate treatment, with over a third being under-investigated. Conclusion The prevalence of anaemia in a UK district general hospital is high. Causes of anaemia are complex, posing a potentially modifiable risk factor for falls, readmission and mortality.
