Approximately 50% of acute intestinal failure (AIF) patients on short-term parenteral nutrition (PN) have intestinal failure-associated liver disease (IFALD) without effect on hospital length of stay and mortality.

INTRODUCTION: Patients with intestinal failure (IF) are often dependent on PN for provision of calories and nutrients for survival. Similar to chronic intestinal failure (CIF) patients, those who have AIF are also at risk of IFALD, which is a poorly understood but potentially fatal condition. The local incidence of IFALD amongst AIF patients is not known. OBJECTIVES: The primary objective of this study was to determine the incidence of IFALD in AIF patients on short-term PN. Secondary objectives were to analyse patient and PN risk factors of IFALD, and clinical outcomes of length of stay (LOS) and inpatient mortality. DESIGN: This was a retrospective cross-sectional cohort study of hospitalised adult patients with AIF prescribed with short-term PN. All adult patients aged 21 years and above who received PN for at least 5 consecutive days and had normal liver function tests (LFTs) at the time of PN initiation were included in this study. RESULTS: A total of 171 patients were enrolled in this study, with 77 (45%) having deranged LFTs at the end of PN therapy and categorised under the IFLAD group. The patient cohort was predominantly male (92 [54%]) and had a median age of 68 years (IQR 59-76). Patients with IFALD at the end of PN therapy had higher diabetes prevalence (36% vs 26%, p = 0.2) and were on PN for a longer duration (median [IQR]: 12 [8-17] vs 8 [6-15] days, p = 0.003) than those without IFALD. There were no significant differences in patient and PN characteristics between the IFLAD and non-IFALD group. The multivariable models showed that the IFALD cohort had longer hospital stays (HR 0.90, 95% CI 0.65-1.23) and lower odds of inpatient death (OR 0.75, 95% CI 0.12-4.60), though both findings are not statistically significant (p = 0.5, 0.7). CONCLUSION: In this study, IFALD is a common phenomenon in AIF and the incidence was found to be an estimated 50% amongst patients on short-term PN with similar clinical outcomes between the two groups.

Long-term effectiveness and persistence rate of ustekinumab dose intensification in a South East Asian inflammatory bowel disease center.

BACKGROUND AND AIMS: Ustekinumab (UST) is an effective biologic for treatment of inflammatory bowel disease (IBD). However, some patients treated with UST have suboptimal clinical response with standard dosing. The aims of this study were to determine the effectiveness of UST dose intensification (DI), identify factors associated with DI, cumulative incidence of DI and persistence of UST among treated patients. METHODS: Clinical data of patients with Crohn's disease (CD) and ulcerative colitis (UC) who received UST from September 2017 to October 2022 in Singapore General Hospital were collected. Primary outcome was defined as achieving corticosteroid-free clinical remission, biochemical remission, endoscopic healing and/or transmural healing (CD). Statistical analysis was performed to identify factors, which are predictive of UST DI and effectiveness of UST DI. RESULTS: Forty-two patients (34 CD and 8 UC) underwent UST DI to either 6-weekly (n = 19, 45.2%) or 4-weekly (n = 23, 35.9%) and the median time to intensification was 31.1 weeks (17.8-65.7). Presence of perianal disease in CD (HR 4.9; 1.47-16.4) was associated with DI. After DI, 16 (38%) patients achieved primary outcome by week 52. The overall drug persistence rates at 1 year and 2 years were 75.7% (95% CI 62.9-84.6) and 63.5% (95% CI 49.9-74.3), respectively. CONCLUSION: Two third of IBD patients underwent DI while on UST treatment and the median time to DI was about 6 months after induction. CD patients with perianal disease is more likely to undergo DI. More than one third of dose-intensified patients achieved remission by week 52.

Parenteral nutrition-related complications in older patients with acute intestinal failure: A descriptive cohort study.

INTRODUCTION: Reported outcomes for parenteral nutrition (PN)-related complications in older adult patients with acute intestinal failure who are receiving PN in the acute hospital setting are limited. Our study aims to compare PN-related complications between older and younger adult patients. METHODS: A retrospective descriptive study of inpatients who were administered PN from January 1, 2019, to December 31, 2019, was performed. Patients were categorized into older (≥65 years old) and younger (<65 years old) adult groups. RESULTS: Two hundred thirty-five patients were included. There were 103 patients in the older adult group (mean age: 73.9 [SD: 6.9] years) and 132 patients in the younger adult group (mean age: 52.4 [SD: 12.5] years). There was a significantly higher Charlson Comorbidity Index score and lower Karnofsky score in the older adult group. The older adult group received significantly lower total energy (20.8 [SD: 7.8] vs 22.8 [SD: 6.3] kcal/kg/day), dextrose (3.1 [SD: 1.4] vs 3.6 [SD: 1.4] g/kg/day), and protein (1.1 [SD: 0.4] vs 1.2 [SD: 0.3] g/kg/day) than the younger group received. The mean length of stay was significantly shorter in the older adult group (35.9 [SD: 21.3] vs 59.8 [SD: 55.3]; P < 0.05). There was no significant difference in PN-related complications and clinical outcomes (catheter-related bloodstream infections, hypoglycemia or hyperglycemia, fluid overload, or inpatient mortality) between the two groups. CONCLUSION: Despite more comorbidities in the older adult, the usage of PN in older adult patients with acute intestinal failure was associated with neither an increased rate of PN-related complications nor worse clinical outcomes when compared with that of younger patients.

Implementation of a Multi-Disciplinary Team and Quality of Goals of Care Discussions in Palliative Surgical Oncology Patients.

BACKGROUND: Palliative surgical oncology patients represent a unique group with complex needs who often require multidisciplinary input for the provision of timely and holistic care. The authors assembled a multi-disciplinary palliative intervention team and evaluated its association with the quality of discussions on goals of care (GOC) among advanced cancer patients undergoing palliative interventions. METHODS: This prospective cohort study analyzed advanced cancer patients undergoing palliative interventions at a single urban academic center from October 2019 to March 2022. In January 2021, a multi-disciplinary palliative surgical intervention (MD-PALS) team was assembled. All palliative surgical oncology patients were discussed at multi-disciplinary meetings and managed by members of the MD-PALS team. An interrupted time series (ITS) model was built to evaluate the association of MD-PALS implementation and the quality of GOC discussions as measured by a consensus-derived four-point GOC discussion quality score. RESULTS: The study recruited 126 palliative surgical oncology patients: 44 in the pre-MD-PALS group and 82 in the post-MD-PALS group. The two groups did not differ significantly in baseline demographics, treatment, or postoperative and survival outcomes. Compared with the pre-MD-PALS group, the post-MD-PALS group had a significantly higher mean GOC discussion quality score (1.34 vs 2.61; p < 0.001). Based on the ITS model, the average quarterly GOC discussion quality score increased significantly among patients after implementation of the MD-PALS team (change = 1.93; 95 % confidence interval, 0.96-2.90; P = 0.003). CONCLUSION: The implementation of an MD-PALS team was associated with improvements in the quality of GOC discussions among palliative surgical oncology patients.

Outpatient screening with the Royal Free Hospital-Nutrition Prioritizing Tool for patients with cirrhosis at risk of malnutrition.

OBJECTIVES: Malnutrition is common among inpatients with cirrhosis. However, data on the prevalence of malnutrition among stable ambulatory patients with cirrhosis is lacking. We sought to investigate the prevalence of patents at risk of malnutrition (ARMN) among ambulatory patients with cirrhosis using the Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT) and the Malnutrition Universal Screening Tool (MUST) and compare their correlation to clinical outcomes. METHODS: Patients attending an outpatient liver cirrhosis clinic at a tertiary hospital were screened for ARMN using both the RFH-NPT and MUST (defined by a score of ≥2 for either tool). Differences in clinical outcomes after 6 mo were compared. RESULTS: There were 134 patients recruited. The RFH-NPT identified more ARMN patients compared with MUST (32.8% versus 8.2%; P < 0.01; Cohen κ, 0.27 [95% CI, 0.12-0.42]; P < 0.001). Fluid overload at recruitment was the only independent predictor of disagreement between the RFH-NPT and MUST (odds ratio [OR], 43.14; 95% CI, 8.70-214.00; P < 0.001). There was a trend toward an increased risk of mortality for ARMN patients by the RFH-NPT (hazard ratio, 3.58; 95% CI, 0.81-15.83; P = 0.06) but not by the MUST (P = 0.62). The incidence of hospital admissions in ARMN patients was higher by the RFH-NPT, with an incidence rate ratio of 13.27 (95% CI, 5.11-43.70; P < 0.001), but not in ARMN patients by the MUST (P = 0.85). Being ARMN by the RFH-NPT was the only independent predictor of hospital admissions (OR, 15.08; 95% CI, 2.47-91.98; P = 0.003). CONCLUSIONS: The RFH-NPT identified more ARMN patients when compared with the MUST, especially among patients with fluid overload. Patients at risk of malnutrition were at an increased risk of hospital admissions and possibly death.

Long term clinical outcomes of home parenteral nutrition in Singapore.

BACKGROUND AND OBJECTIVES: Home parenteral nutrition (HPN) is a life sustaining therapy for patients with chronic intestinal failure. Reported outcomes for Asian HPN patients are scarce. We aim to review the clinical outcomes of adult and paediatric HPN patients in our cohort which caters for 95% of Singaporean HPN patients. METHODS AND STUDY DESIGN: This is a retrospective review of HPN patients from an adult (2002-2017) and paediatric cohort (2011-2017) from the largest tertiary PN centres in Singapore. Patient demographics and clinical outcomes were reviewed. RESULTS: There were 41 adult and 8 paediatric HPN patients. Mean age was 53.0(±15.1) (adults) and 8(±1.8) years-old (paediatrics). Mean duration of HPN was 2.6(±3.5) and 3.5(±2.5) years. Leading indications for adult HPN were short bowel syndrome (SBS) (n=19,46.3%), mechanical obstruction (n=9,22.0%), and gastrointestinal dysmotility disorders (GID) (n=5,12.2%). Thirteen adult (31.7%) patients had underlying malignancy, with seven (17.3%) receiving palliative HPN. Indications for HPN amongst paediatric patients was GID (n=5,62.5%) and SBS (n=3,37.5%). Central line-associated bloodstream infection (CLABSI)/1000catheter-days was 1.0(±2.1) and 1.8(±1.3). Catheter associated venous thrombosis (CAVT)/1000catheter-days was 0.1(±0.4) and 0.7(±0.8). Biochemical Intestinal Failure Associated Liver Disease (IFALD) was found in 21.9% and 87.5%. For adults, median overall survival was 90-months (4.3,175.7,95%CI), with actuarial survival of 70.7%(1-year) and 39.0%(5-years). Median survival for adult patients with malignancy was 6-months (4.2,7.7,95%CI), actuarial survival of 85.7%(3-months) and 30.7%(1-year). One adult patient died from PN related complications. No paediatric deaths were noted. CONCLUSIONS: Whilst patient numbers were modest, we report comparable complication and survival rates to other international centres in both our adult and paediatric cohorts.

Approximately 1 in 10 ambulatory inflammatory bowel disease patients are at risk of malnutrition: A prospective Singapore cohort.

OBJECTIVES: Prevalence of malnutrition among ambulatory inflammatory bowel disease (IBD) patients in Singapore is unknown. We aimed to evaluate the prevalence of ambulatory IBD patients at risk of malnutrition (ARMN) using Malnutrition Universal Screening Tool (MUST) and its clinical outcomes. METHODS: IBD patients were recruited from March to June 2018 and followed up for 6 months. ARMN patients were defined as having a MUST score of 2 or more compared with those not at risk (non-ARMN). RESULTS: Altogether 217 patients were recruited, including 128 (59.0%) with ulcerative colitis (UC) and 89 (41.0%) with Crohn's disease (CD). The mean body mass index (BMI) was 23.5 ± 4.5 kg/m2 ; 35 (16.1%) patients were on biologics, and 52 (24.0%) were on steroids. Among them 25 (11.5%) patients were ARMN, with a predominance of UC (n = 15, 60.0%). The majority of ARMN patients were underweight (n = 23, 92.0%) while 114 (59.4%) non-ARMN patients were overweight. ARMN patients had a significantly lower albumin (38.3 g/L vs 41.9 g/L) and a significantly increased proportion of patients with C-reactive protein ≥5 mg/L (36.0% vs 19.3%). There was a trend towards longer hospital stay among ARMN patients, although this was not statistically significant. Use of biologics or immunomodulators and albumin levels were associated with being ARMN. CONCLUSION: Using MUST, 11.5% of our ambulatory IBD patients in Singapore were identified to be ARMN. Among ARMN patients, a trend was demonstrated towards a longer hospital stays for admitted patients. This underscores the need to actively screen ambulatory IBD patients for malnutrition.

Motorized spiral enteroscopy versus double-balloon enteroscopy: a case-matched study.

BACKGROUND AND AIMS: Motorized spiral enteroscopy (MSE) has been postulated to ease the complexities of the standard-of-care double-balloon enteroscopy (DBE). However, there are no comparative studies between MSE and DBE. This study aimed to compare the therapeutic outcomes and safety between MSE and DBE. METHODS: In this case-matched study, patients were matched 1:2 (MSE/DBE) by age, sex, body mass index, and American Society of Anesthesiology scores. Thirty-one patients who underwent MSE were compared with 62 patients who underwent DBE from 2014 to 2022. Our primary outcomes were to compare the technical and diagnostic success rates between DBE and MSE. Our secondary outcomes were to compare the therapeutic success and adverse event rates. RESULTS: The main indications for enteroscopy were suspected GI bleeding and positive radiologic findings. Prior abdominal surgery was reported in 35.5% and 22.6% of DBE and MSE patients, respectively. Most were antegrade enteroscopy (71%). We found no significant difference in the technical success (DBE 98.4% vs MSE 96.8%, P = .62), diagnostic success (DBE 66.1% vs MSE 54.8%, P = .25), and therapeutic success rates (DBE 62.8% vs MSE 52.9%, P = .62) between the groups. Adverse events occurred in 1 DBE and 11 MSE patients. Most were minor (n = 10, 25.6%). Two patients (5.1%) in the MSE group sustained deep lacerations in the proximal esophagus requiring hospitalization. One developed ileal perforation after MSE needing surgical repair. CONCLUSIONS: In patients requiring enteroscopy, the diagnostic and therapeutic performance of MSE is similar to DBE. An increased frequency of adverse events was observed with MSE. There are some restrictions in the indication because of the design of MSE.

Clinical utility of thiopurine metabolite monitoring in inflammatory bowel disease and its impact on healthcare utilization in Singapore.

Background and Aim: Thiopurines are recommended for maintenance of steroid-free remission (SFR) in inflammatory bowel disease (IBD). Thiopurine metabolite monitoring (MM) is increasingly used in the West but remains novel in Singapore, with limited information on its therapeutic and economic benefits. Hence, this study aims to investigate MM's clinical utility and its impact on healthcare resource utilization in Singaporean IBD patients. Methods: A retrospective observational study was conducted at Singapore General Hospital outpatient IBD Centre. Patients with IBD, baseline MM during 2014-2017, and weight-based thiopurine doses for ≥4 weeks were followed up for 1 year. Actions were taken to optimize therapy, and metabolite levels before and after the first action were documented. Outcomes assessed included SFR, no therapy escalation or surgery, healthcare resource utilization, and direct healthcare costs. Results: Ninety IBD patients (50 Crohn's disease, 40 ulcerative colitis) were included. Among them, 40% had baseline metabolite levels within therapeutic range, 31.1% sub-therapeutic, 21.1% supra-therapeutic, and 7.8% shunters. Repeated MM with subsequent dose optimization helped 67.2% of patients achieve therapeutic levels after 1 year. Overall, 87.8% of patients achieved SFR and 90% had no therapy escalation or surgery. Despite greater outpatient visits and laboratory investigations with MM, the median total healthcare costs at 1 year only increased marginally (S$6407.66 [shunters] vs S$5215.20 [supra-therapeutic] vs S$4970.80 [sub-therapeutic] vs S$4370.48 [control (within therapeutic range)], P = 0.592). Conclusion: MM guided timely therapy escalation for non-responders, identification of non-adherence, and reversal of shunting. Therefore, it is a useful clinical tool to optimize thiopurines without significantly increasing healthcare costs.

Favorable vaccine-induced SARS-CoV-2-specific T cell response profile in patients undergoing immune-modifying therapies.

BACKGROUNDPatients undergoing immune-modifying therapies demonstrate a reduced humoral response after COVID-19 vaccination, but we lack a proper evaluation of the effect of such therapies on vaccine-induced T cell responses.METHODSWe longitudinally characterized humoral and spike-specific T cell responses in patients with inflammatory bowel disease (IBD), who were on antimetabolite therapy (azathioprine or methotrexate), TNF inhibitors, and/or other biologic treatment (anti-integrin or anti-p40) for up to 6 months after completing 2-dose COVID-19 mRNA vaccination.RESULTSWe demonstrate that a spike-specific T cell response was not only induced in treated patients with IBD at levels similar to those of healthy individuals, but also sustained at higher magnitude for up to 6 months after vaccination, particularly in those treated with TNF inhibitor therapy. Furthermore, the spike-specific T cell response in these patients was mainly preserved against mutations present in SARS-CoV-2 B.1.1.529 (Omicron) and characterized by a Th1/IL-10 cytokine profile.CONCLUSIONDespite the humoral response defects, patients under immune-modifying therapies demonstrated a favorable profile of vaccine-induced T cell responses that might still provide a layer of COVID-19 protection.FUNDINGThis study was funded by the National Centre for Infectious Diseases (NCID) Catalyst Grant (FY2021ES) and the National Research Fund Competitive Research Programme (NRF-CRP25-2020-0003).

The use of standardized commercially available parenteral nutrition as a bridge to customized compounded bag in the acute hospital setting is safe and feasible.

BACKGROUND & AIMS: The use of standardized commercially available parenteral nutrition (SCAPN) as a starter bag to bridge to customized compounded PN offers the advantage of starting PN on the same day of consult, avoiding delays in nutrition delivery. We aim to evaluate the safety and feasibility of using SCAPN as a bridge to compounded PN in the acute hospital setting. METHODS: Retrospective review of patients on PN from Aug 2018 to Sep 2019 was performed. SMOFKABIVEN® Peripheral 800 kcal in 1206 ml was used. Electrolyte replacements on the day and the day after PN commencement were compared between SCAPN and compounded PN. Results were reported as means (95% confidence intervals). P value < 0.05 was considered statistically significant. RESULTS: 135 (78.5%) patients received SCAPN while 37 (21.5%) received compounded PN on the first day of PN. Baseline characteristics of both groups were almost similar with higher BMI in the SCAPN. Baseline serum potassium 4.0 (3.9, 4.1) vs 4.0 (3.8, 4.1), p = 0.46; phosphate 1.1 (1.0, 1.1) vs 1.1 (1.0, 1.3), p = 0.40 and magnesium 0.8 (0.8, 0.9) vs 0.9 (0.9, 1.0), p < 0.05 for SCAPN and compounded PN respectively. Follow-up serum potassium was 3.9 (3.8, 3.9) vs 3.9 (3.8, 4.1), p = 0.36; phosphate 0.9 (0.9, 0.9) vs 1.1 (1.0, 1.2), p < 0.05 and magnesium 0.9 (0.9, 0.9) vs 0.9 (0.9, 1.0), p = 0.18. Baseline calories and protein were lower in SCAPN group. Electrolyte replacements were similar in both groups at baseline and follow up. CONCLUSION: Using our in-house protocol, the use of a SCAPN as a bridge to customized compounded PN is safe and feasible.

Home parenteral nutrition patients on mixed oil lipid emulsion have a higher rate of hospitalizations compare to those on soybean oil- a prospective 2-year cohort study.

BACKGROUND & AIMS: Mixed oil intravenous lipid emulsion (MO ILE) that contains 30% soybean oil (SO), 30% medium chain triglycerides, 25% olive oil and 15% fish oil can benefit hospitalized patients receiving parenteral nutrition (PN) but there are very few studies on its long-term use. Our goal was to evaluate the clinical outcomes of adults receiving home PN (HPN) with MO versus those receiving SO ILE over a 2-year period. METHOD: This is a retrospective analysis of data collected prospectively from a cohort of patients recorded in the Canadian HPN Registry over a 2-year period. HPN patients from academic programs across Canada were entered in the Registry according to a validated protocol. For this study, demographic, nutritional, laboratory and clinical data were extracted from January 1st 2015, when MO lipid emulsion became available in Canada, to July 24th 2019. Clinical data for each patient included: number of hospitalizations, number of hospitalizations related to HPN and number of hospitalization days related to HPN, over a year; incidence of line sepsis per 1000 catheter days and mortality. Data are presented as median (1st, 3rd quartile) for continuous variables and frequency (percentage) for categorical variables. Comparisons between groups were performed using two sample t-test or Wilcoxon Rank Sum tests for continuous variables and Chi-square tests or Fisher's exact tests for categorical variables. Univariate and multiple linear regressions were also carried out. Statistical significance is set at a p-value <0.05. RESULTS: A total of 120 patients were included (MO n = 68, SO n = 52). Significant differences at baseline between the two groups were a higher use of Hickman line (62.12% vs 42%, p = 0.038) and more western Canada based hospital care with MO (75% vs 42.31%, p = 0.0002). The MO group had significantly more hospitalizations (p = 0.001), more hospitalizations related to HPN (p = 0.012) and more hospitalization days related to HPN (p = 0.016) per patient per year compared to SO patients. There was no significant difference between groups for line sepsis per 1000 catheter days (MO: 0.05 (0.0, 1.0) vs SO: 0.0 (0.0, 0.22), p = 0.053) or mortality. All other variables, including biochemical variables, were similar between groups. In a multiple regression analysis, the following factors were significantly associated with a greater number of hospitalizations per patient per year: use of MO, high blood glucose from the last recorded value and having died by the end of the study period. CONCLUSION: This 2-year prospective cohort study suggests an increased risk of hospitalization in HPN patients receiving MO lipid emulsion. The long-term effect of using MO lipid emulsion in HPN patients should be further evaluated using a large randomized controlled trial. THE STUDY WAS REGISTERED IN CLINICALTRIALS.GOV: (NCT02299466).

Olive oil-based lipid emulsion is noninferior to soybean oil-based lipid emulsion in the acute care setting: A double-blind randomized controlled trial.

OBJECTIVES: Olive oil (OO)-based intravenous lipid emulsion (IVLE) may have biological advantages for nutrition and inflammation status compared with soybean oil (SO)-based IVLE. We aimed to compare prealbumin levels during infusion of OO- or SO-based IVLE in patients receiving parenteral nutrition in the acute-care setting. METHODS: In this prospective, noninferiority, double blind randomized controlled efficacy trial, patients received either OO-based or SO-based IVLE after providing consent. Biochemical and nutrition parameters were collected at baseline and at 7 to 10 d after initiation of parenteral nutrition. Results are expressed as means (standard deviations). RESULTS: A total of 210 patients completed the study: 102 patients in the SO-based IVLE group and 108 patients in the OO-based IVLE group. Both groups had a significant increase in prealbumin levels from baseline (SO: 0.10 [0.06] versus 0.15 [0.08] g/L; P < 0.0001; OO: 0.11 [0.06] versus 0.16 [0.08] g/L; P < 0.0001), but mean changes between groups were not different (P = 0.53). OO-based IVLE was noninferior to SO-based IVLE in maintaining or increasing serum prealbumin levels, with 20% as the noninferiority margin at follow-up (least square geometric mean ratio [95% CI], 1.10 [0.83,1.47]; P = 0.50). There was a significant improvement in C-reactive protein levels from baseline within each group (SO: 83.24 [69.72] versus 53.4 [59.78] mg/dL; P < 0.0001; OO: 85.13 [68.14] versus 58.75 [60.11] mg/dL; P = 0.004), but mean changes between the groups were not different (P = 0.836). Mortality, length of stay, and infection rates were not different for both groups. CONCLUSIONS: In this study, OO-based IVLE was not inferior to SO-based IVLE in maintaining or increasing the prealbumin level. The improvement of C-reactive protein levels and other clinical outcomes were not different for both groups.

Vaccinations and inflammatory bowel disease - a systematic review.

INTRODUCTION: Patients with inflammatory bowel disease(IBD) are at risk of infections, many of which are preventable with vaccinations. We performed a systematic review on various aspects of vaccination in IBD. METHODS: We searched PubMed, and EMBASE databases, through 31 January 2021. Primary outcomes included vaccination rates, predictors of vaccination, reasons of vaccination hesitancy and acceptance, and outcomes of intervention. Findings were presented with medians, ranges, and narrative synthesis. RESULTS: We included 33 observational studies comprising 146,918 patients and 681 physicians. The median vaccination rates of influenza, pneumococcal pneumonia, and hepatitis B vaccines were 42%(IQR, 28%-61.5%), 20%(IQR, 9%-38.5%), and 48%(IQR, 29%-53%), respectively. Uses of immunosuppressant, older age and physician recommendations have positive influence on vaccination rate. Lack of vaccine-related knowledge and awareness of need for vaccination are main reasons of vaccine hesitancy among patients and physicians. There was disagreement between gastroenterologists and primary-care physicians on whose responsibility to offer vaccination. Education was the sole intervention identified, with variable success. CONCLUSION: This systematic review demonstrates that the vaccination rates of IBD patients, similar to other chronic diseases, are suboptimal. Lack of vaccine-related knowledge and awareness of the need for vaccination are main reasons of vaccine hesitancy amongst patients and physicians. Education, though effective, was the only available intervention identified. Gastroenterologist could take the lead in educating, and initiating vaccination among IBD patients.

Modified minimal-contact COVID-19 workflow allows for safe, remote parenteral nutrition prescribing in non-critically ill patients.

BACKGROUND: In line with recent guidance from the American Society for Parenteral and Enteral Nutrition (ASPEN) and the European Society for Clinical Nutrition and Metabolism (ESPEN) to minimize healthcare team exposure by clustering care and relying on other providers or telehealth to collect relevant nutrition assessments, our nutrition support team has adopted a modified workflow using information technology to provide parenteral nutrition (PN) remotely in a safe and timely manner. We aim to compare our prescribing adequacy and PN-related complications before and during the coronavirus disease 2019 (COVID-19) outbreak using the modified workflow in non-critically ill patients. METHODS: This study reviewed a prospectively recruited cohort of adults receiving PN in the general wards or high-dependency units from December 5, 2019, to April 15, 2020. Demographic data, nutrition assessment, PN prescriptions, blood results, electronic notes, capillary blood glucose monitoring, and catheter-related bloodstream infection rates were reviewed for patients who received PN. RESULTS: We found that patients who started PN during COVID-19 were more malnourished with lower body mass index and higher proportion of Subjective Global Assessment B/C scores (52 [92.9%] vs 36 [73.5%], P < .005). The proportion of patients who achieved target energy amounts within 5 days was similar in both groups. Protein prescription was >1 g/kg/day in both groups, though there was a trend of higher protein prescription during COVID-19. Complications were similar in both groups. CONCLUSION: Our study demonstrates that minimal contact with effective multidisciplinary communication using the modified workflow can allow for safe and timely PN administration.

More than Pus - Primary Hepatic Epithelioid Angiomyolipoma Masquerading as Liver Abscess.

Hepatic angiomyolipomas (AML) are rare mesenchymal tumours of which the epithelioid type is a rare type with malignant potential. We report a case of primary hepatic epithelioid angiomyolipoma masquerading as liver abscess. A 46-year-old man presented with a 5-day history of fever with epigastric pain and nausea. On the night of admission, his temperature spiked to 39°C, his blood pressure was 135/79, his heart rate 98, his liver function test revealed albumin 37 g/L, bilirubin 25 µmol/L, ALP 298 U/L, ALT 247 U/L, and AST 344 U/L. The clinical suspicion was hepatobiliary sepsis and intravenous ceftriaxone was commenced. CT of the abdomen showed an ill-defined hypodense focus in segment 4A/8 (4.5 × 3.5 cm) with a minimal fluid component implying a developing abscess or phlegmon. The images were reviewed by a radiologist and showed minimal fluid for percutaneous drainage. MRI of the liver was performed to further characterize the lesion and revealed a solid mass with nodular areas of arterial enhancement and washout, suspicious of neoplasm. Ultrasound-guided liver biopsy of the lesion was performed. Histology showed a histiocyte-rich epithelioid neoplasm consistent with the epithelioid variant of AML. Immunohistochemical staining was positive for human melanoma black 45, melan-A and cluster of differentiation 68. He successfully underwent liver resection of segment 4A/8 after 6 weeks of antibiotics. To our knowledge, this is the first reported case in the literature of primary hepatic epithelioid angiomyolipoma masquerading as liver abscess.

Patients With Severe Gastrointestinal Dysmotility Disorders Receiving Home Parenteral Nutrition Have Similar Survival As Those With Short-Bowel Syndrome: A Prospective Cohort Study.

INTRODUCTION: Severe gastrointestinal dysmotility disorder (GID) constitute approximately 20% of patients requiring home parenteral nutrition (HPN), whereas short-bowel syndrome (SBS) remains the most frequent indication for HPN. This study's aim was to characterize GID patients and compare clinical parameters and survival to SBS patients. Similarly, clinical comparisons between sclerodermaand nonscleroderma patients were made. METHODS: Demographic and clinical data for all patients was extracted from the Canadian HPN Registry from January 1, 2003, to November 1, 2018. Kaplan-Meier method was used to estimate the unadjusted survival probability, and log-rank test was used to compare the survival probability between groups. RESULT: 270 patients (52 GID and 218 SBS) were included in the analysis. For all patients, higher mortality was associated with age (hazard ratio [HR], 1.02 [1.00-1.04]; P = .05), PN dependence (HR, 1.01 [1.00-1.02]; P = .04), hospitalizations (HR, 1.21 [1.10-1.33]; P < .001), and use of immunosuppressant (HR, 1.97 [1.02-3.82]; P = .04). The 5- and 10-year actuarial survival probabilities between GID and SBS were not significantly different (5-year: 70.0% vs 59.2%; 10-year: 79.6% vs 66.2% [P = .5], respectively). There was no difference in survival between scleroderma and nonscleroderma patients (P = .67). CONCLUSION: T5- and 10- year survival probabilities were similar between GID and SBS patients. The diagnosis of scleroderma had no effect on survival. Use of immunosuppressant, older age, PN dependence, and number of hospitalizations per PN duration are risk factors for mortality in both the GID and SBS groups.

Rapid and Safe Crossing of the Chasm: Application of a Flipped Learning Framework for the Clipping Over the Scope Technique.

Training practicing physicians to adopt new technology may be difficult because most endoscopy training is given during fellowship training. As such, the adoption of new technology in gastroenterology is typically slow. We designed our course to train our cohort of practicing physicians using flipped learning, a pedagogical approach in which instructional cognitive content is delivered to the individual instead of the group, usually through online platforms and outside of the classroom. We describe our methods and results of the training courses on the techniques of clipping over the scope for gastrointestinal bleeding and endoscopic balloon dilation.
