Evaluating an obstetrics and gynecology teaching program for medical students incorporating simulation-based education underpinned by cognitive load theory.

Although there have been previous publications on curriculum innovations in teaching O&G to medical students, especially utilizing simulation-based education, there have been none, as far as we know, incorporating and evaluating the outcomes using cognitive load theory. The aim of this article was to describe the introduction, implementation, and evaluation of an innovative teaching program in O&G, incorporating simulation-based education, underpinned by cognitive load theory. Cognitive load is defined as the amount of information a working memory can hold at any one time and incorporates three types of cognitive load-intrinsic, extraneous, and germane. To optimize learning, educators are encouraged to manage intrinsic cognitive load, minimize extraneous cognitive load, and promote germane cognitive load. In these sessions, students were encouraged to prepare in advance of each session with recommended reading materials; to limit intrinsic cognitive load and promote germane cognitive load, faculty were advised ahead of each session to manage intrinsic cognitive load, an open-book MCQ practice session aimed to reduce anxiety, promote psychological safety, and minimize extraneous cognitive load. For the simulation sessions, the faculty initially demonstrated the role-play situation or clinical skill first, to manage intrinsic cognitive load and reduce extraneous cognitive load. The results of the evaluation showed that the students perceived that they invested relatively low mental effort in understanding the topics, theories, concepts, and definitions discussed during the sessions. There was a low extraneous cognitive load. Measures of germane cognitive load or self-perceived learning were high. The primary message is that we believe this teaching program is a model that other medical schools globally might want to consider adopting, to evaluate and justify innovations in the teaching of O&G to medical students. The secondary message is that evaluation of innovations to teaching and facilitation of learning using cognitive load theory is one way to contribute to the high-quality training of competent future healthcare workers required to provide the highest standard of care to women who are crucial to the overall health and wellbeing of a nation.

Study protocol for a Randomised controlled trial of EArly transjugular intrahepatiC porTosystemic stent-shunt in Acute Variceal Bleeding (REACT-AVB trial).

INTRODUCTION: In liver cirrhosis, acute variceal bleeding (AVB) is associated with a 1-year mortality rate of up to 40%. Data on early or pre-emptive transjugular intrahepatic portosystemic stent-shunt (TIPSS) in AVB is inconclusive and may not reflect current management strategies. Randomised controlled trial of EArly transjugular intrahepatiC porTosystemic stent-shunt in AVB (REACT-AVB) aims to investigate the clinical and cost-effectiveness of early TIPSS in patients with cirrhosis and AVB after initial bleeding control. METHODS AND ANALYSIS: REACT-AVB is a multicentre, randomised controlled, open-label, superiority, two-arm, parallel-group trial with an internal pilot. The two interventions allocated randomly 1:1 are early TIPSS within 4 days of diagnostic endoscopy or secondary prophylaxis with endoscopic therapy in combination with non-selective beta blockers. Patients aged ≥18 years with cirrhosis and Child-Pugh Score 7-13 presenting with AVB with endoscopic haemostasis are eligible for inclusion. The primary outcome is transplant-free survival at 1 year post randomisation. Secondary endpoints include transplant-free survival at 6 weeks, rebleeding, serious adverse events, other complications of cirrhosis, Child-Pugh and Model For End-Stage Liver Disease (MELD) scores at 6 and 12 months, health-related quality of life, use of healthcare resources, cost-effectiveness and use of cross-over therapies. The sample size is 294 patients over a 4-year recruitment period, across 30 hospitals in the UK. ETHICS AND DISSEMINATION: Research ethics committee of National Health Service has approved REACT-AVB (reference number: 23/WM/0085). The results will be submitted for publication in a peer-reviewed journal. A lay summary will also be emailed or posted to participants before publication. TRIAL REGISTRATION NUMBER: ISRCTN85274829; protocol version 3.0, 1 July 2023.

Professionalism-training in undergraduate medical education in a multi-cultural, multi-ethnic setting in the Gulf Region: an exploration of reflective essays.

BACKGROUND: Despite the established need to prioritize professionalism-training in developing future physicians, very few medical programs in the Gulf Region embed in their curricula discrete contextualized courses aimed at developing the corresponding competencies, while fostering self-directed learning. This study aims at exploring the perception of undergraduate medical students in a multi-cultural, multi-ethnic setting regarding their understanding of, and personal experience with professionalism through their engagement with the content of an innovative curriculum-based professionalism course, offered at a Medical School in Dubai, United Arab Emirates. METHODS: The study used a qualitative phenomenological research design. Out of 33 students, 29 students had submitted reflective essays. The content of these essays was inductively analyzed following a six-step framework for conducting thematic analysis. The framework's steps include familiarizing oneself with the data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report. FINDINGS: The inductive qualitative analysis generated the Professionalism Learning Journey model. This conceptual model includes four interconnected themes: Awareness, Acknowledgement, Realization, and Application. The generated model depicts the trajectory that the learners appear to experience while they are engaging with the content of the course. CONCLUSION: Integrating a professionalism-training course into an undergraduate medical curriculum is likely to be positively appraised by the learners. It raises their awareness, enables them to value the subject matter and the sophistication of its application, and empowers them to put into practice the taught principles, on an individual basis and collectively. This is especially true when the course is entrenched in constructivism experiential learning theory and designed to foster self-directed learning. The introduced conceptual model, in conjunction with the innovative professionalism-training course curriculum, can serve as a template for other competencies and other schools.

Impact of the COVID-19 pandemic on patients with hepatocellular carcinoma in the West of Scotland: a cohort study.

OBJECTIVE: The COVID-19 pandemic had an undoubted impact on the provision of elective and emergency cancer care, including the diagnosis and management of patients with hepatocellular carcinoma (HCC). Our aim was to determine the effects of the COVID-19 pandemic on patients with HCC in the West of Scotland. DESIGN: This was a retrospective audit of a prospectively collated database of patients presented to the West of Scotland Multidisciplinary Team (MDT) between April and October 2020 (during the pandemic), comparing baseline demographics, characteristics of disease at presentation, diagnostic workup, treatment and outcomes with patients from April to October 2019 (pre pandemic). RESULTS: There was a 36.5% reduction in new cases referred to the MDT during the pandemic. Patients presented at a significantly later Barcelona Cancer Liver Clinic stage (24% stage D during the pandemic, 9.5% pre pandemic, p<0.001) and with a significantly higher Child-Pugh Score (46% Child-Pugh B/C during the pandemic vs 27% pre pandemic, p<0.001). We observed a reduction in overall survival (OS) among all patients with a median OS during the pandemic of 6 months versus 17 months pre pandemic (p=0.048). CONCLUSION: The impact of the COVID-19 pandemic is likely to have contributed to a reduction in the presentation of new cases and survival among patients with HCC in the West of Scotland. The reason for this is likely multifactorial, but disruption of standard care is likely to have played a significant role. Resources should be provided to address the backlog and ensure there are robust investigation and management pathways going forward.

Guidance document: risk assessment of patients with cirrhosis prior to elective non-hepatic surgery.

As a result of the increasing incidence of cirrhosis in the UK, more patients with chronic liver disease are being considered for elective non-hepatic surgery. A historical reluctance to offer surgery to such patients stems from general perceptions of poor postoperative outcomes. While this is true for those with decompensated cirrhosis, selected patients with compensated early-stage cirrhosis can have good outcomes after careful risk assessment. Well-recognised risks include those of general anaesthesia, bleeding, infections, impaired wound healing, acute kidney injury and cardiovascular compromise. Intra-abdominal or cardiothoracic surgery are particularly high-risk interventions. Clinical assessment supplemented by blood tests, imaging, liver stiffness measurement, endoscopy and assessment of portal pressure (derived from the hepatic venous pressure gradient) can facilitate risk stratification. Traditional prognostic scoring systems including the Child-Turcotte-Pugh and Model for End-stage Liver Disease are helpful but may overestimate surgical risk. Specific prognostic scores like Mayo Risk Score, VOCAL-Penn and ADOPT-LC can add precision to risk assessment. Measures to mitigate risk include careful management of varices, nutritional optimisation and where possible addressing any ongoing aetiological drivers such as alcohol consumption. The role of portal decompression such as transjugular intrahepatic portosystemic shunting can be considered in selected high-risk patients, but further prospective study of this approach is required. It is of paramount importance that patients are discussed in a multidisciplinary forum, and that patients are carefully counselled about potential risks and benefits.

Clinical learning environments across two different healthcare settings using the undergraduate clinical education environment measure.

BACKGROUND: The clinical placements of our medical students are almost equally distributed across private and public sectors. This study aims to assess medical students' perceptions of their Clinical learning Environment (CLE) across these two different healthcare settings, using the Undergraduate Clinical Education Environment Measure (UCEEM). METHODS: 76 undergraduate medical students (Year 5 and 6), were invited to participate. Data were collected using an online UCEEM with additional questions related to demographics and case load exposure. The UCEEM consists of two overarching domains of experiential learning and social participation, with four subdomains of learning opportunities, preparedness, workplace interaction, and inclusion. RESULTS: 38 questionnaires were received. Of 225 responses to the individual UCEEM items, 51 (22.6%) scored a mean of ≥ 4 (range 4-4.5, representing strong areas), 31 (13.7%) scored a mean of ≤ 3 (range 2.1-3, needing attention) and 143 (63.6%) scored a mean of 3.1-3.9 (areas that could be improved). The majority (63%) of the case load exposure responses scored a mean of ≥ 4 (range 4-4.5). Compared to the private sittings, there is a significant reduction in total UCEEM (p = 0.008), preparedness for student entry (p = 0.003), and overarching dimension of social participation (p = 0.000) scores for the public sector. Similarly, both workplace interaction patterns and student inclusion and equal treatment scored significantly lower for the public sector (p = 0.000 and p = 0.011 respectively). Two out of three case load exposure items scored significantly higher for the public sector (p = 0.000). DISCUSSION: The students' CLE perceptions were generally positive. The lower UCEEM ratings in the public sector items were related to student entry preparedness, workplace interactions, student inclusiveness and workforce equity of treatment. In contrast the students were exposed to more variety and larger number of patients in the public sector. These differences indicated some significantly different learning environments between the two sectors.

A Review of Risk Scores within Upper Gastrointestinal Bleeding.

Upper gastrointestinal bleeding is a common medical emergency. Thorough initial assessment and appropriate resuscitation are essential to stabilise the patient. Risk scores provide an important tool to discriminate between lower- and higher-risk patients. Very low-risk patients can be safely discharged for out-patient management, while higher-risk patients can receive appropriate in-patient care. The Glasgow Blatchford Score, with a score of 0-1, performs best in the identification of very low-risk patients who will not require hospital based intervention or die, and is recommended by most guidelines to facilitate safe out-patient management. The performance of risk scores in the identification of specific adverse events to define high-risk patients is less accurate, with no individual score performing consistently well. Ongoing developments in the use of machine learning models and artificial intelligence in predicting poor outcomes in UGIB appear promising and will likely form the basis of dynamic risk assessment in the future.

The relationship of online pre-recorded neurology mini-lectures to medical student assessment: a pilot study.

INTRODUCTION: eLearning has become an essential part of medical education. However, there is a lack of published research on student engagement with online pre-recorded mini-lectures and its relation to assessment. The aim of this pilot study is to explore the relationship between newly introduced neurology pre-recorded mini-lectures and undergraduate medical students engagement and assessment. This may encourage the wider use of mini-lectures in undergraduate medical curricula. METHODS: The engagement of medical students with 48 online pre-recorded neurology mini-lectures was assessed through a Learning Management System. To measure engagement, data was stratified according to the number of watched/downloaded mini-lectures. A point system was used (out of 5): - 1 point = watching/downloading 0-10 mini-lectures, 2 points = watching/downloading 11-20 mini-lectures, 3 points = watching/downloading 21-30 mini-lectures, 4 points = watching/downloading 31-40 mini-lectures and, 5 points = watching/downloading 41-48 mini-lectures. The students' engagement was correlated with their neurology assessments [Objective Structured Clinical Examination (OSCE), and knowledge-based assessment 10 Multiple Choice Questions (MCQs) and one 10-mark Short Answer Question, (SAQ)], internal medicine grade and annual grade point average (GPA) using the Pearson correlation coefficient. RESULTS: The mean engagement of 34, Year 5, medical students is 3.9/5. There is a significant positive correlation between engagement and internal medicine grade (r = 0.35, p = 0.044). There is a moderate correlation between engagement and neurology OSCE (r = 0.23), annual Year 5 GPA (r = 0.23), neurology knowledge-based score (r = 0.22) and composite neurology knowledge/OSCE (r = 0.27). The knowledge-based assessment included SAQ and MCQs: there was a moderate correlation with SAQ (r = 0.30), but a weak negative correlation with the MCQs (r =-0.11). Sub-groups analysis comparing the top- and low- or non- engaging students made these weaker correlations stronger. CONCLUSION: This pilot study indicates a high rate of engagement with an online pre-recorded mini-lectures resource and evidence of moderate correlation between engagement and assessment. Online pre-recorded mini-lectures should be used more in delivering the curriculum contents of the clinical clerkships. Further studies are needed to evaluate the relation and the impact of the mini-lectures on assessment.

A literature review and proposed framework for a core curriculum in obstetrics and gynecology for medical students globally.

BACKGROUND: There have been challenges in deciding the curricular content in obstetrics and gynecology (Ob/Gyn) for medical students because the core knowledge, competencies, and duration of Ob/Gyn clerkships, varies widely by country. OBJECTIVES: To investigate current recommendations for Ob/Gyn curricula for medical students globally, in a rapid review of the literature and websites of a selection of medical schools. SEARCH STRATEGY: A targeted search of selected databases (PubMed and Google Scholar) using relevant key words and a search of university websites. SELECTION CRITERIA: Studies that applied to medical or undergraduate students in Ob/Gyn. DATA COLLECTION AND ANALYSIS: A standardized extraction form on Microsoft excel to extract and chart data. MAIN RESULTS: We identified recommendations from national professional bodies (Royal College of Obstetricians and Gynaecologists, Royal Australian and New Zealand College of Obstetricians and Gynaecologists, Association of Professors of Gynecology and Obstetrics, and the Turkish-National Core Curriculum), and descriptions from five university websites. We also identified additional objectives, including teaching on intimate partner violence, health priorities in low- and middle-income countries, and a variation in practical skills recommended. CONCLUSIONS: Fitting all the recommended curricula content into medical student Ob/Gyn clerkships is a challenge. A framework to address this, for consideration by the International Federation of Gynaecology and Obstetrics and other stakeholders, is proposed in which priority is given to topics related to emergency Ob/Gyn, history taking, and examination of the pregnant and non-pregnant patient.

Hepatocellular Carcinoma Risk Scores Predict Patients Under Surveillance at Low Risk of Benefit and High Risk of Harm.

AIMS: Surveillance for hepatocellular carcinoma (HCC) is recommended for patients with cirrhosis. Multiple risk scores aim to stratify HCC risk, potentially allowing individualized surveillance strategies. We sought to validate four risk scores and quantify the consequences of surveillance via the calculation of numbers needed to benefit (NNB) and harm (NNH) according to classification by risk score strata. METHODS: Data were collected on 482 patients with cirrhosis during 2013-2014, with follow-up until 31/12/2019. Risk scores (aMAP, Toronto risk index, ADRESS HCC, HCC risk score) were derived from index clinic results. The area under the receiving operating characteristic curve (AUC) was calculated for each. Additionally, per-risk strata, NNB was calculated as total surveillance ultrasounds per surveillance diagnosed early HCC (stage 0/A) and NNH as total ultrasounds performed per false positive (abnormal surveillance with normal follow-up imaging). RESULTS: 22 (4.6%) patients developed HCC. 77% (17/22) were diagnosed through surveillance, of which 13/17 (76%) were early stage. There were 88 false positives and no false negatives (normal surveillance result however subsequent HCC detection). Overall NNB and NNH were 241 and 36, respectively. No score was significantly superior using AUC. Patients classified as low risk demonstrated no surveillance benefit (AMAP, THRI) or had a high NNB of > 300/900 (ADRESS HCC, HCC risk score), with low NNH (24-38). CONCLUSION: Given the lack of benefit and increased harm through false positives in low-risk groups, a risk-based surveillance strategy may have the potential to reduce patient harm and increase benefit from HCC surveillance. CLINICAL TRIALS REGISTRATION: This was not a clinical trial and the study was not pre-registered.

Effect of time to pre-emptive transjugular intrahepatic portosystemic shunt on patient outcome, a UK multicentre cohort study.

BACKGROUND: Pre-emptive transjugular intrahepatic portosystemic shunt (pTIPSS) should be considered within 72 hours following acute oesophageal variceal bleeding. However, recent studies highlight the difficulty in providing pTIPSS within this narrow timeframe. Delaying pTIPSS beyond 72 hours has not been studied. AIM: To determine if the time taken to perform pTIPSS alters patient outcome. METHOD: Patients referred to 4 UK tertiary centres for pTIPSS between 01 January 2010 and 31 December 2018 were included. Time from endoscopy to pTIPSS was recorded and pre-defined clinically relevant outcomes were observed relative to two groups: early pTIPSS (<72 h) and late pTIPSS (72 h-28 days). The primary outcome was transplant-free survival at 1-year. Follow-up was until 31 December 2020. RESULTS: A total of 83 patients received early pTIPSS and 88 received late pTIPSS. Baseline characteristics were similar with no requirement for propensity score-matched analysis. There was no difference between early and late pTIPSS groups for patient outcomes; 1-year transplant-free survival rate (69.9% vs 71.6%, p = 0.73, HR 0.91, 95% CI 0.52-1.58), long-term survival (p = 0.52, HR 1.132, 95% CI 0.77-1.65), variceal rebleeding (4.82% vs 11.36%, p = 0.09, HR 0.411, 95% CI 0.14-1.17), hepatic encephalopathy (43.93% vs 34.61%, p = 0.26) and new or worsening ascites (16.6% vs 13.46%, p = 0.79). Death due to liver failure was significantly more prevalent in those undergoing early pTIPSS compared to late pTIPSS (44% vs 16%, p = 0.046, HR 2.79, 95%CI 1.02-8.32). CONCLUSION: Placement of pTIPSS within 72 hours offered similar short- and long-term survival benefits compared to pTIPSS placed between 72 hours and 28 days. Early pTIPSS may be associated with an increased risk of liver failure-related mortality. Further large, randomised studies are required to evaluate these findings.

Rebleeding in peptic ulcer bleeding - a nationwide cohort study of 19,537 patients.

BACKGROUND: Rebleeding is a frequent complication of peptic ulcer bleeding (PUB). The associated prognosis remains rather unclear because previous studies generally also included non-ulcer lesions. OBJECTIVE: We aimed to identify predictors for rebleeding; clarify the prognostic consequence of rebleeding; and develop a score for predicting rebleeding. METHODS: Nationwide cohort study of consecutive patients presenting to hospital with PUB in Denmark from 2006-2014. Logistic regression analyses were used to identify predictors for rebleeding, evaluate the association between rebleeding and 30-day mortality, and develop a score to predict rebleeding. Patients with persistent bleeding were excluded. RESULTS: Among 19,258 patients (mean age 74 years, mean ASA-score 2.4), 10.8% rebled, and 10.2% died. Strongest predictors for rebleeding were endoscopic high-risk stigmata of bleeding (Odds Ratio (OR): 2.12 [95% Confidence Interval (CI): 1.91-2.36]), bleeding from duodenal ulcers (OR: 1.87 [95% CI: 1.69-2.08]), and presentation with hemodynamic instability (OR: 1.55 [95% CI: 1.38-1.73]). Among patients with all three factors (7.9% of total), 24% rebled, 50% with rebleeding failed endoscopic therapy, and 23% died. Rebleeding was associated with increased mortality (OR: 2.04 [95% CI: 1.78-2.32]). We were unable to develop an accurate score to predict rebleeding. CONCLUSION: Rebleeding occurs in ∼10% of patients with PUB and is overall associated with a two-fold increase in 30-day mortality. Patients with hemodynamic instability, duodenal ulcers, and high-risk endoscopic stigmata are at highest risk of rebleeding. When rebleeding occurs in such patients, consultation with surgery and/or interventional radiology should be obtained prior to repeat endoscopy.

Increasing the low-risk threshold for patients with upper gastrointestinal bleeding during the COVID-19 pandemic: a prospective, multicentre feasibility study.

Objective: During the COVID-19 pandemic, we extended the low-risk threshold for patients not requiring inpatient endoscopy for upper gastrointestinal bleeding (UGIB) from Glasgow Blatchford Score (GBS) 0-1 to GBS 0-3. We studied the safety and efficacy of this change. Methods: Between 1 April 2020 and 30 June 2020 we prospectively collected data on consecutive unselected patients with UGIB at five large Scottish hospitals. Primary outcomes were length of stay, 30-day mortality and rebleeding. We compared the results with prospective prepandemic descriptive data. Results: 397 patients were included, and 284 index endoscopies were performed. 26.4% of patients had endoscopic intervention at index endoscopy. 30-day all-cause mortality was 13.1% (53/397), and 33.3% (23/69) for pre-existing inpatients. Bleeding-related mortality was 5% (20/397). 30-day rebleeding rate was 6.3% (25/397). 84 patients had GBS 0-3, of whom 19 underwent inpatient endoscopy, 0 had rebleeding and 2 died. Compared with prepandemic data in three centres, there was a fall in mean number of UGIB presentations per week (19 vs 27.8; p=0.004), higher mean GBS (8.3 vs 6.5; p<0.001) with fewer GBS 0-3 presentations (21.5% vs 33.3%; p=0.003) and higher all-cause mortality (12.2% vs 6.8%; p=0.02). Predictors of mortality were cirrhosis, pre-existing inpatient status, age >70 and confirmed COVID-19. 14 patients were COVID-19 positive, 5 died but none from UGIB. Conclusion: During the pandemic when services were under severe pressure, extending the low-risk threshold for UGIB inpatient endoscopy to GBS 0-3 appears safe. The higher mortality of patients with UGIB during the pandemic is likely due to presentation of a fewer low-risk patients.

International multicenter study comparing demographics, therapy and outcomes in bleeding from Mallory Weiss tears and peptic ulcers.

Background and study aims Mallory Weiss tears (MWTs) are relatively uncommon causes of upper gastrointestinal bleeding (UGIB), and patients are generally considered at low risk of poor outcome, although data are limited. There is uncertainty about use of endoscopic therapy. We aimed to describe and compare an international cohort of patients presenting with UGIB secondary to MWT and peptic ulcer bleeding (PUB). Patients and methods From an international dataset of patients undergoing endoscopy for acute UGIB at seven hospitals, we assessed patients with MWT bleeding, including the endoscopic stigmata and endoscopic therapy applied. We compared baseline parameters, rebleeding rate, and 30-day mortality between patients with MWT and PUB. Results A total of 3648 patients presented with UGIB, 125 of whom (3.4 %) had bleeding from a MWT. Those patients were younger (61 vs 69 years, P  < 0.0001) and more likely to be men (66 % vs 53 %, P  = 0.006) compared to the patients PUB. The most common endoscopic stigmata seen in MWTs were oozing blood (26 %) or clean base (26 %). Of the patients with MWT, 53 (42 %) received endoscopic therapy. Forty-eight of them (90 %) had epinephrine injections and 25 (48 %) had through-the-scope clips. The rebleeding rate was lower in MWT patients compared with PUB patients (4.9 % vs 12 %, P  = 0.016), but mortality was similar (5.7 vs 7.0 %, P  = 0.71). Conclusions Although patients presenting with MWT were younger, with a lower rebleeding rate, their mortality was similar to that of patients with PUB. Endoscopic therapy was applied to 42 % MWT patients, with epinephrine injection as the most common modality.

Carvedilol versus endoscopic band ligation for secondary prophylaxis of variceal bleeding-long-term follow-up of a randomised control trial.

BACKGROUND AND AIMS: Carvedilol reduces rates of variceal bleeding and rebleeding by lowering portal pressure. However, an associated pleiotropic survival benefit has been proposed. We aimed to assess long-term survival in a cohort of patients previously randomised to receive either carvedilol or endoscopic band ligation (EBL) following oesophageal variceal bleeding (OVB). METHODS: The index study randomised 64 cirrhotic patients with OVB between 2006 and 2011 to receive either carvedilol or EBL. Follow-up was undertaken to April 2020 by review of electronic patient records. The primary outcome was survival. Other outcomes including variceal rebleeding and liver decompensation events were compared. RESULTS: 26 out of 33 participants received carvedilol in the follow-up period and 28 out of 31 attended regular EBL sessions. The median number of follow-up days for all patients recruited was 1459 (SE = 281.74). On the intention to treat analysis, there was a trend towards improved survival in the carvedilol group (p = 0.09). On per-protocol analysis, carvedilol use was associated with improved long-term survival (p = 0.005, HR 3.083, 95% CI 1.397-6.809), fewer liver-related deaths (0% vs 22.57%, p = 0.013, OR ∞, 95%CI 1.565-∞) and fewer admissions with decompensated liver disease (12% vs 64.29%, p = 0.0002, OR 13.2, 95% CI 3.026-47.23) compared to the EBL group. There was no statistically significant difference in variceal rebleeding rates. CONCLUSION: Following OVB in cirrhotic patients, carvedilol use is associated with survival benefit, fewer liver-related deaths and fewer hospital admissions with decompensated liver disease. Further studies are needed to validate this finding.

Update on the management of upper gastrointestinal bleeding.

Upper gastrointestinal bleeding is a common emergency presentation requiring prompt resuscitation and management. Peptic ulcers are the most common cause of the condition. Thorough initial management with a structured approach is vital with appropriate intravenous fluid resuscitation and use of a restrictive transfusion threshold of 7-8 g/dL. Pre-endoscopic scoring tools enable identification of patients at high risk and at very low risk who might benefit from specific management. Endoscopy should be carried out within 24 h of presentation for patients admitted to hospital, although optimal timing for patients at a higher risk within this period is less clear. Endoscopic treatment of high risk lesions and use of subsequent high dose proton pump inhibitors is a cornerstone of non-variceal bleeding management. Variceal haemorrhage results in higher mortality than non-variceal haemorrhage and, if suspected, antibiotics and vasopressors should be administered urgently, before endoscopy. Oesophageal variceal bleeding requires endoscopic band ligation, whereas bleeding from gastric varices requires thrombin or tissue glue injection. Recurrent bleeding is managed by repeat endoscopic treatment. If uncontrolled bleeding occurs, interventional radiological embolisation or surgery is required for non-variceal bleeding or transjugular intrahepatic portosystemic shunt placement for variceal bleeding.
