RESUMO
To compare 5-year gastroesophageal reflux outcomes following Laparoscopic Vertical Sleeve Gastrectomy (LVSG) and Laparoscopic Roux-en-Y gastric bypass (LRYGB) based on high quality randomized controlled trials (RCTs). We conducted a sub-analysis of our systematic review and meta-analysis of RCTs of primary LVSG and LRYGB procedures in adults for 5-year post-operative complications (PROSPERO CRD42018112054). Electronic databases were searched from January 2015 to July 2021 for publications meeting inclusion criteria. The Hartung-Knapp-Sidik-Jonkman random effects model was utilized to estimate weighted mean differences where meta-analysis was possible. Bias and certainty of evidence was assessed using the Cochrane Risk of Bias Tool 2 and GRADE. Four RCTs were included (LVSG n = 266, LRYGB n = 259). An increase in adverse GERD outcomes were observed at 5 years postoperatively in LVSG compared to LRYGB in all outcomes considered: Overall worsened GERD, including the development de novo GERD, occurred more commonly following LVSG compared to LRYGB (OR 5.34, 95% CI 1.67 to 17.05; p = 0.02; I2 = 0%; (Moderate level of certainty); Reoperations to treat severe GERD (OR 7.22, 95% CI 0.82 to 63.63; p = 0.06; I2 = 0%; High level of certainty) and non-surgical management for worsened GERD (OR 3.42, 95% CI 1.16 to 10.05; p = 0.04; I2 = 0%; Low level of certainty) was more common in LVSG patients. LVSG is associated with the development and worsening of GERD symptoms compared to LRYGB at 5 years postoperatively leading to either introduction/increased pharmacological requirement or further surgical treatment. Appropriate patient/surgical selection is critical to minimize these postoperative risks.

BACKGROUND: Data on nutrition delivery over the whole hospital admission in critically ill patients with COVID-19 are scarce, particularly in the Australian setting. OBJECTIVES: The objective of this study was to describe nutrition delivery in critically ill patients admitted to Australian intensive care units (ICUs) with coronavirus disease 2019 (COVID-19), with a focus on post-ICU nutrition practices. METHODS: A multicentre observational study conducted at nine sites included adult patients with a positive COVID-19 diagnosis admitted to the ICU for >24 h and discharged to an acute ward over a 12-month recruitment period from 1 March 2020. Data were extracted on baseline characteristics and clinical outcomes. Nutrition practice data from the ICU and weekly in the post-ICU ward (up to week four) included route of feeding, presence of nutrition-impacting symptoms, and nutrition support received. RESULTS: A total of 103 patients were included (71% male, age: 58 ± 14 years, body mass index: 30±7 kg/m2), of whom 41.7% (n = 43) received mechanical ventilation within 14 days of ICU admission. While oral nutrition was received by more patients at any time point in the ICU (n = 93, 91.2% of patients) than enteral nutrition (EN) (n = 43, 42.2%) or parenteral nutrition (PN) (n = 2, 2.0%), EN was delivered for a greater duration of time (69.6% feeding days) than oral and PN (29.7% and 0.7%, respectively). More patients received oral intake than the other modes in the post-ICU ward (n = 95, 95.0%), and 40.0% (n = 38/95) of patients were receiving oral nutrition supplements. In the week after ICU discharge, 51.0% of patients (n = 51) had at least one nutrition-impacting symptom, most commonly a reduced appetite (n = 25; 24.5%) or dysphagia (n = 16; 15.7%). CONCLUSION: Critically ill patients during the COVID-19 pandemic in Australia were more likely to receive oral nutrition than artificial nutrition support at any time point both in the ICU and in the post-ICU ward, whereas EN was provided for a greater duration when it was prescribed. Nutrition-impacting symptoms were common.

BACKGROUND: The COVID-19 pandemic highlighted major challenges with usual nutrition care processes, leading to reports of malnutrition and nutrition-related issues in these patients. OBJECTIVE: The objective of this study was to describe nutrition-related service delivery practices across hospitalisation in critically ill patients with COVID-19 admitted to Australian intensive care units (ICUs) in the initial pandemic phase. METHODS: This was a multicentre (nine site) observational study in Australia, linked with a national registry of critically ill patients with COVID-19. Adult patients with COVID-19 who were discharged to an acute ward following ICU admission were included over a 12-month period. Data are presented as n (%), median (interquartile range [IQR]), and odds ratio (OR [95% confidence interval {CI}]). RESULTS: A total of 103 patients were included. Oral nutrition was the most common mode of nutrition (93 [93%]). In the ICU, there were 53 (52%) patients seen by a dietitian (median 4 [2-8] occasions) and malnutrition screening occurred in 51 (50%) patients most commonly with the malnutrition screening tool (50 [98%]). The odds of receiving a higher malnutrition screening tool score increased by 36% for every screening in the ICU (1st to 4th, OR: 1.39 [95% CI: 1.05-1.77] p = 0.018) (indicating increasing risk of malnutrition). On the ward, 51 (50.5%) patients were seen by a dietitian (median time to consult: 44 [22.5-75] hours post ICU discharge). The odds of dietetic consult increased by 39% every week while on the ward (OR: 1.39 [1.03-1.89], p = 0.034). Patients who received mechanical ventilation (MV) were more likely to receive dietetic input than those who never received MV. CONCLUSIONS: During the initial phases of the COVID-19 pandemic in Australia, approximately half of the patients included were seen by a dietitian. An increased number of malnutrition screens were associated with a higher risk score in the ICU and likelihood of dietetic consult increased if patients received MV and as length of ward stay increased.

BACKGROUND AND AIM: No marker to categorise the severity of chronic intestinal failure (CIF) has been developed. A 1-year international survey was carried out to investigate whether the European Society for Clinical Nutrition and Metabolism clinical classification of CIF, based on the type and volume of the intravenous supplementation (IVS), could be an indicator of CIF severity. METHODS: At baseline, participating home parenteral nutrition (HPN) centres enrolled all adults with ongoing CIF due to non-malignant disease; demographic data, body mass index, CIF mechanism, underlying disease, HPN duration and IVS category were recorded for each patient. The type of IVS was classified as fluid and electrolyte alone (FE) or parenteral nutrition admixture (PN). The mean daily IVS volume, calculated on a weekly basis, was categorised as <1, 1-2, 2-3 and >3 L/day. The severity of CIF was determined by patient outcome (still on HPN, weaned from HPN, deceased) and the occurrence of major HPN/CIF-related complications: intestinal failure-associated liver disease (IFALD), catheter-related venous thrombosis and catheter-related bloodstream infection (CRBSI). RESULTS: Fifty-one HPN centres included 2194 patients. The analysis showed that both IVS type and volume were independently associated with the odds of weaning from HPN (significantly higher for PN <1 L/day than for FE and all PN >1 L/day), patients' death (lower for FE, p=0.079), presence of IFALD cholestasis/liver failure and occurrence of CRBSI (significantly higher for PN 2-3 and PN >3 L/day). CONCLUSIONS: The type and volume of IVS required by patients with CIF could be indicators to categorise the severity of CIF in both clinical practice and research protocols.

BACKGROUND AND AIM: Chronic intestinal failure requiring home parenteral nutrition (HPN) is a disabling condition that is best facilitated by a multidisciplinary approach to care. Variation in care has been identified as a key barrier to achieving quality of care for patients on HPN and requires appropriate strategies to help standardize management. METHOD: The Australasian Society for Parenteral and Enteral Nutrition (AuSPEN) assembled a multidisciplinary working group of 15 clinicians to develop a quality framework to assist with the standardization of HPN care in Australia. Obstacles to quality care specific to Australia were identified by consensus. Drafts of the framework documents were based on the available literature and refined by two Delphi rounds with the clinician work group, followed by a further two involving HPN consumers. The Oxford Centre for Evidence-Based Medicine Levels of Evidence was used to assess the strength of evidence underpinning each concept within the framework documents. RESULTS: Quality indicators, standards of care, and position statements have been developed to progress the delivery of quality care to HPN patients. CONCLUSION: The quality framework proposed by AuSPEN is intended to provide a practical structure for clinical and organizational aspects of HPN service delivery to reduce variation in care and improve quality of care and represents the initial step towards development of a national model of care for HPN patients in Australia. While developed for implementation in Australia, the evidence-based framework also has relevance to the international HPN community.

The key complications of allogeneic bone marrow transplantation (BMT) remain graft-versus-host disease (GVHD) and opportunistic infection. We have analyzed the blood stream infections (BSIs) occurring between day -7 and day 100 in a cohort of 184 adult patients undergoing allogeneic BMT in our center. A total of 167 of the 184 patients (91%) had blood cultures collected, and 69 (38%) patients had a confirmed BSI. Enterobacteriaceae, Pseudomonas aeruginosa, Enterococcus spp., and viridans Streptococcus spp. were the most commonly isolated organisms. Gender, conditioning (myeloablative versus reduced intensity), and donor type (sibling versus unrelated) did not differ significantly between those with and without confirmed BSI. Elevated temperature (>38°C) at the time of culture collection was associated with an almost 2-fold increased likelihood of returning a positive blood culture. The absence of a BSI was associated with a significant improvement in overall survival at 2 years, due to a significant reduction in nonrelapse mortality predominantly unrelated to the primary BSI. The presence of a BSI before engraftment was associated with the dysregulation of IL-6 and IL-8. Our findings suggest that BSI early after BMT defines a group of high-risk patients with enhanced cytokine dysregulation and poor transplant outcome.

BACKGROUND: The prevalence of type 2 diabetes is growing in both developed and developing countries and is strongly linked with the prevalence of obesity. Bariatric surgical procedures such as laparoscopic vertical sleeve gastrectomy (LVSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are increasingly being utilized to manage related comorbid chronic conditions, including type 2 diabetes. METHODS: A systematic review of randomized controlled trials (RCTs) was undertaken using the PRISMA guidelines to investigate the postoperative impact on diabetes resolution following LVSG versus LRYGB. RESULTS: Seven RCTs involving a total of 732 patients (LVSG n = 365, LRYGB n = 367) met inclusion criteria. Significant diabetes resolution or improvement was reported with both procedures across all time points. Similarly, measures of glycemic control (HbA1C and fasting blood glucose levels) improved with both procedures, with earlier improvements noted in LRYGB that stabilized and did not differ from LVSG at 12 months postoperatively. Early improvements in measures of insulin resistance in both procedures were also noted in the studies that investigated this. CONCLUSIONS: This systematic review of RCTs suggests that both LVSG and LRYGB are effective in resolving or improving preoperative type 2 diabetes in obese patients during the reported 3- to 5-year follow-up periods. However, further studies are required before longer-term outcomes can be elucidated. Areas identified that need to be addressed for future studies on this topic include longer follow-up periods, standardized definitions and time point for reporting, and financial analysis of outcomes obtained between surgical procedures to better inform procedure selection.

BACKGROUND: Home parenteral nutrition (HPN) is a life-saving therapy required for the management of type III intestinal failure, one of the rarest organ failures. It requires a multidisciplinary approach to manage the complexity of the underlying medical, surgical, and nutrition issues, but the current levels of healthcare funding in Australia are unknown. This study aimed to quantify the caseload, staffing, and capacity of existing HPN centers nationally. METHODS: This was a cross-sectional survey inviting centers known to provide HPN care. The survey was designed to capture metrics related to the national framework for the delivery of HPN. These centered on staffing levels, patient load, capacity to audit key outcomes, and service challenges. RESULTS: A total of 24 (89%) of 27 invited centers responded to the survey. There were 17 (71%) adult centers and 7 (29%) pediatric centers. Adult centers managed a median of 12 (interquartile range [IQR]: 6-25) patients vs 16 (IQR: 9-17) in pediatric centers. Several centers did not have dedicated funding for core team members. The total funded clinician time each week per patient was 7 min (IQR: 0-12 min) in adult centers and 14 min (IQR: 10-21 min) in pediatric centers. Fewer than half of centers reported having sufficient resources to regularly audit key metrics. CONCLUSION: The availability of dedicated expertise to manage the highly complex needs of people living with type III intestinal failure is lacking in Australia. Current funding of HPN services falls well short of being sufficient to meet the requirements outlined in the national quality framework.

BACKGROUND: Patients with chronic intestinal failure (CIF) may be predisposed to poor oral health outcomes. This study explored the self-reported oral health status, function, and psychological impacts of oral health of adult patients with CIF, their access to dental care, and how these compare with the broader population. METHODS: All patients >18 years old receiving home intravenous therapies for CIF were invited to complete a self-reported questionnaire providing information on oral health status and access to oral health services. Collateral information was provided by treating clinicians. Descriptive data analysis was undertaken, including subgroup analysis of clinical characteristics, and was compared with the available population-level data. RESULTS: Twenty-four patients participated. Short gut and dysmotility accounted for 88% of the etiologies of CIF. Respondents reported good preventative oral health behaviors (96%), accessing dental care within the last 12 months (75%), and limited barriers to receiving care. Dry mouth (96%), oral pain (59%), and temperature sensitivity (60%) were commonly reported across the cohort. Smoking history and reduced oral diet were associated with significantly worse self-reported oral health outcomes. Patients with CIF reported worse oral health outcomes despites better oral health access than the general population. CONCLUSION: Patients with CIF appear to be at risk of poor oral health outcomes, especially where smoking or reduced oral intake are concurrently involved. Clinicians involved in CIF care should be alert to the oral health needs of this population and consider oral and dental health as part of the multidisciplinary care required for optimal CIF care.
RESUMO
BACKGROUND & AIMS: Pelvic exenteration (PE) surgery is now a widely accepted procedure that is increasingly being performed worldwide but has significant morbidity. Although nutrition status, body mass index (BMI) and postoperative nutrition support practices are modifiable risk factors, few studies have examined the relationship of these with clinical outcomes following PE. The aim of this study was therefore to investigate the impact of these factors on postoperative complications and length of hospital stay (LOHS) following PE. METHODS: This was a retrospective cohort study of all patients having total PE surgery at a tertiary teaching hospital from 2012 to 2021 (n = 69). Multivariable analyses were undertaken to confirm univariate associations and adjust for confounding variables. Binary logistic regression was undertaken to explore predictors of infectious and Grade III or above Clavien-Dindo complications, and negative binomial regression to identify predictors of LOHS. RESULTS: Patients who were malnourished according to the Subjective Global Assessment were 5.66 (OR 5.66, 95% CI 1.07-29.74, p = 0.041) times more likely to develop an infectious complication. Increasing BMI was independently associated with development of Grade III or above Clavien-Dindo complications (p = 0.040). For each additional day until full diet commencement, there was a 19% (OR: 1.19, 95% CI 1.05-1.34, p = 0.005) increased incidence of significant complications and a 5.6% (IRR: 1.056, 95% CI: 1.02-1.09, p = 0.002) longer LOHS on multivariable analysis. There was a high rate of prolonged postoperative ileus (78%). The implementation of a nutrition support pathway with routine postoperative parenteral nutrition (PN) resulted in patients achieving adequate nutrition 7 days faster (p < 0.001) with minimal line-related complications (1.4% line-related thrombus). Routine PN did not impact ileus rates (p = 0.33) or time to diet commencement (p = 0.6). CONCLUSIONS: Preoperative malnutrition and higher BMI were associated with complications following PE. Delay to full diet commencement was associated with increased complications and longer LOHS. Routine postoperative PN appears safe and resulted in patients achieving adequate nutrition faster.

BACKGROUND: Peripheral parenteral nutrition (PPN) represents an alternative option to central parenteral nutrition (CPN) for patients requiring short-term parenteral nutrition (PN). We hypothesized that the use of PPN could be increased in certain patient cohorts referred for PN in our facility. METHODS: A retrospective observational study investigating the clinical characteristics of patients receiving PN under the nutrition support team over a 5-year period was undertaken. Patients who received PPN were reviewed descriptively. Of the patients who received CPN, representative samples were grouped into those who received PN for ≤7 or >7-28 days (n = 100 each, randomly assigned). Clinical characteristics considered included indication, duration and referring team for PN, and nutrition status. Descriptive statistics and binary logistic regression model for predictors of PN duration of ≤7 or >7-28 days were derived. RESULTS: Only four patients received PPN for a median of 4 days, most of whom required this route because of loss of central venous access for CPN. A high proportion of patients with no enteral access received CPN for ≤7 days, whereas the majority of patients with malabsorption required >7-28 days of CPN. Being referred for PN following upper gastrointestinal surgery increased the likelihood of CPN use for >7 days (relative risk, 5.7; 95% CI, 1.7-18.9; P = 0.004). CONCLUSION: Within our service, PN referrals for no enteral access may represent a group in whom PPN could be used in the first instance; those referred with an indication of malabsorption or following upper gastrointestinal surgery may benefit from early commencement of CPN.

BACKGROUND: Laparoscopic vertical sleeve gastrectomy (LVSG) is now the most commonly performed bariatric procedure; however, it remains to be elucidated if it delivers equivalent long-term comorbid disease resolution outcomes similar to the longer established laparoscopic Roux-en-Y gastric bypass (LRYGB). We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the comparative 5-year outcomes of both procedures. METHODS: Electronic databases (Pubmed, EMBASE, CINAHL) were searched for RCTs conducted in adults (>18y) that compared the 5-year- outcomes of LVSG to LRYGB and described comorbidity outcomes were included. Where data allowed, effect sizes were calculated using the Hartung-Knapp-Sidik-Jonkman estimation method for random effects model. Presence of bias was assessed with Cochrane Risk of Bias 2.0 and funnel plots, and certainty of evidence evaluated by GRADE. The study prospectively registered with PROSPERO (CRD42018112054). RESULTS: Three RCTs (LVSG=254, LRYGB=255) met inclusion criteria and reported on chronic disease outcomes. Improvement and/or resolution of hypertension favoured LRYGB (odds ratio 0.49, 95% CI 0.29, 0.84; P =0.03). Trends favoring LRYGB were seen for type 2 diabetes and dysplidemia, and LVSG for sleep apnea and back/joint conditions ( P >0.05). The certainty of evidence associated with each assessed outcome ranged from low to very low, in the setting of 'some' to 'high' bias assessed as being present. CONCLUSION: Both LRYGB and LVSG are effective in providing long-term improvements in commonly experienced obesity-related comorbidities; however, the limited certainty of the evidence does not allow for strong clinical conclusions to be made at this time regarding benefit of one procedure over the other.

BACKGROUND: Adherence to perioperative guideline recommendations for prophylactic supplementation and regular biochemical monitoring is suboptimal. However, little is known about the patient perspective on this postoperative challenge. OBJECTIVES: To qualitatively explore patient experiences of postoperative micronutrient management and identify patient-reported barriers and facilitators to the provision of nutrition care. SETTING: Two tertiary public hospitals in Queensland, Australia. METHODS: Semi-structured interviews were conducted with 31 participants 12 months after bariatric surgery. Inductive analysis of interview transcripts was performed using applied thematic analysis, and deductive analysis was performed by aligning interview themes against the Theoretical Domains Framework and the Capability, Motivation, and Opportunity Behavior Change Wheel Framework. RESULTS: Participants' perceptions of engagement with the bariatric surgery multidisciplinary team greatly influenced their experience with overall nutrition care, including but not exclusive to micronutrient care. At times, this engagement negatively impacted patients' experiences with their nutrition care and related to varied acceptance of healthcare advice from the team or, at times, an unmet desire for person-centered communication styles. Engaging person-centered care techniques had a positive influence on patient experience with micronutrient and overall nutrition care. Micronutrient management (taking supplements and having regular blood tests) was broadly accepted and enabled by the presence of established medication and blood test routines preoperatively. However, challenges did exist and were practical in nature. Incorporating education on habit-forming techniques was identified as a facilitator to assist with micronutrient management. CONCLUSION: Although participants mostly accept embedding micronutrient management into their life, developing interventions that focus on habit-forming skills and that enable multidisciplinary teams to provide person-centered care is recommended to enhance care after surgery.

AIMS: This study aimed to explore the multidisciplinary team attitudes and knowledge of bariatric surgery micronutrient management (pre- and postoperative care) and to evaluate the implementation of an extended-scope of practice dietitian-led model of care for micronutrient monitoring and management. METHODS: A mixed method study design included quantitative evaluation of micronutrient testing practices and deficiency rates. Qualitative reflexive thematic analysis was used to interpret multidisciplinary experience with micronutrient monitoring in a traditional and dietitian-led model of care. In addition, deductive analysis used normalisation process theory mapping of multidisciplinary experience with the implementation of the dietitian-led model of care. RESULTS: In the traditional model, a lack of quality evidence to guide micronutrient management, and a tension in trust between surgeons and patients related to adherence to micronutrient prescriptions were described as challenges in current practice. The dietitian-led model was seen to overcome some of these challenges, increasing collaborative, and coordinated, consistent and personalised patient care that led to increased testing for and detection of micronutrient deficiencies. Barriers to sustainability of the dietitian-led model included a lack of workforce succession planning, and no clearly defined delegation for some aspects of care. CONCLUSION: An extended scope dietitian-led model of care for micronutrient management after bariatric surgery improves clinical care. Challenges such as succession planning must be considered in design of extended scope services.
RESUMO
BACKGROUND: Bariatric surgery may increase the risk of micronutrient deficiencies; however, confounders including preoperative deficiency, supplementation and inflammation are rarely considered. OBJECTIVE: To examine the impact of bariatric surgeries, supplementation and inflammation on micronutrient deficiency. SETTING: Two public hospitals, Australia. METHODS: Participants were recruited to an observational study monitoring biochemical micronutrient outcomes, supplementation dose, inflammation and glycaemic control, pre-operatively and at 1-3, 6 and 12 months after gastric bypass (GB; Roux-en-Y Gastric Bypass and Single Anastomosis Gastric Bypass; N = 66) or sleeve gastrectomy (SG; N = 144). Participant retention at 12 months was 81%. RESULTS: Pre-operative micronutrient deficiency was common, for vitamin D (29-30%), iron (13-22%) and selenium (39% GB cohort). Supplement intake increased after surgery; however, dose was <50% of target for most nutrients. After SG, folate was vulnerable to deficiency at 6 months (OR 13 [95% CI 2, 84]; p = 0.007), with folic acid supplementation being independently associated with reduced risk. Within 1-3 months of GB, three nutrients had higher deficiency rates compared to pre-operative levels; vitamin B1 (21% vs. 6%, p < 0.01), vitamin A (21% vs. 3%, p < 0.01) and selenium (59% vs. 39%, p < 0.05). Vitamin B1 deficiency was independently associated with surgery and inflammation, selenium deficiency with improved glycaemic control after surgery and inflammation, whilst vitamin A deficiency was associated with inflammation only. CONCLUSION: In the setting of prophylactic post-surgical micronutrient prescription, few nutrients are at risk of de novo deficiency. Although micronutrient supplementation and monitoring remains important, rationalising high-frequency biochemical testing protocols in the first year after surgery may be warranted.

BACKGROUND AND AIMS: To investigate the incidence and the severity of COVID-19 infection in patients enrolled in the database for home parenteral nutrition (HPN) for chronic intestinal failure (CIF) of the European Society for Clinical Nutrition and Metabolism (ESPEN). METHODS: Period of observation: March 1st, 2020 March 1st, 2021. INCLUSION CRITERIA: patients included in the database since 2015 and still receiving HPN on March 1st, 2020 as well as new patients included in the database during the period of observation. Data related to the previous 12 months and recorded on March 1st 2021: 1) occurrence of COVID-19 infection since the beginning of the pandemic (yes, no, unknown); 2) infection severity (asymptomatic; mild, no-hospitalization; moderate, hospitalization no-ICU; severe, hospitalization in ICU); 3) vaccinated against COVID-19 (yes, no, unknown); 4) patient outcome on March 1st 2021: still on HPN, weaned off HPN, deceased, lost to follow up. RESULTS: Sixty-eight centres from 23 countries included 4680 patients. Data on COVID-19 were available for 55.1% of patients. The cumulative incidence of infection was 9.6% in the total group and ranged from 0% to 21.9% in the cohorts of individual countries. Infection severity was reported as: asymptomatic 26.7%, mild 32.0%, moderate 36.0%, severe 5.3%. Vaccination status was unknown in 62.0% of patients, non-vaccinated 25.2%, vaccinated 12.8%. Patient outcome was reported as: still on HPN 78.6%, weaned off HPN 10.6%, deceased 9.7%, lost to follow up 1.1%. A higher incidence of infection (p = 0.04), greater severity of infection (p < 0.001) and a lower vaccination percentage (p = 0.01) were observed in deceased patients. In COVID-19 infected patients, deaths due to infection accounted for 42.8% of total deaths. CONCLUSIONS: In patients on HPN for CIF, the incidence of COVID-19 infection differed greatly among countries. Although the majority of cases were reported to be asymptomatic or have mild symptoms only, COVID-19 was reported to be fatal in a significant proportion of infected patients. Lack of vaccination was associated with a higher risk of death.

BACKGROUND AND AIMS: The micronutrient status of those receiving long-term enteral nutrition (EN) is poorly characterised. This systematic review was undertaken to determine prevalence of micronutrient deficiency in those receiving EN; the impact of the route of feeding; whether underlying disease or clinical factors were associated with micronutrient status; and the efficacy of interventions utilised to treat identified micronutrient deficiency. METHODS: Electronic databases (CINAHL, Embase, PubMed, Web of Science) were searched to June 2021 for publications of primary investigation of micronutrient status in adults or children (>5yrs) receiving EN for >2 months in their usual residence. Independent assessment of compliance with inclusion criteria (Covidence®), data extraction of predefined data points, assessment of basis (Academy of Dietetics Quality Checklist) and certainty of evidence (GRADE) was assessed by at least two authors. (PROSPERO Registration: CRD42021261113). RESULTS: Thirty-one studies (n = 744) met inclusion criteria. Deficiency was reported for copper, zinc, selenium, beta-carotene, and vitamins A, D and E: Only copper, zinc and selenium were associated with physical/haematological manifestations of deficiency. Jejunal feeding was associated with the development of copper deficiency and often required gastric or parenteral replacement to resolve the issue. Circumstances leading to deficiency included receiving feed products formulated with inadequate amounts of the implicated nutrient, low feed product volumes in the context of low macronutrient requirements, and nutritional decline prior to commencement of EN. Potential confounding factors such as inflammation were rarely accounted for. No studies investigated the contribution of underlying clinical condition on micronutrient status, and no other clinical or demographic features appeared to impact outcomes. Reported methods for treating identified deficiencies were usually successful in reversing deficiency symptoms. The certainty of evidence is very low, and the level of bias moderate to high. CONCLUSION: While the evidence is very uncertain about the effect of long-term enteral feeding on the development of micronutrient deficiencies, clinicians should be alert to the possibility of micronutrient deficiency developing in long-term EN fed patients. Those who may be at increased risk are those receiving nutrition into the jejunum, those who meet macronutrient requirements in low volumes of EN product, and those commencing EN in a nutritionally deplete state. Further research and surveillance of micronutrient status with contemporary EN products and practices is required.

BACKGROUND: There is a paucity of data that compares the relative complication profiles of laparoscopic vertical sleeve gastrectomy (LVSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) at 5 years. OBJECTIVES: The aim was to compare late complications of LVSG and LRYGB. METHODS: We updated our previous systematic review and meta-analysis of randomized controlled trials of primary LVSG and LRYGB procedures in adults, to review late (5 years) complication outcomes (PROSPERO 112054). Electronic databases were searched from January 2015 to July 2021 for publications meeting inclusion criteria. The Hartung-Knapp-Sidik-Jonkman random effects model was utilized to estimate weighted mean differences where meta-analysis was possible. Bias and certainty of evidence was assessed using the Cochrane risk of bias tool and Grading of Recommendations, Assessment, Development and Evaluations. RESULTS: Four randomized controlled trials met the inclusion criteria (n=531; LVSG=272, LRYGB=259). No late treatment-related mortality was reported with either procedure. A significant reduction in surgical reoperations (odds ratio: 0.47, 95% confidence interval: 0.27-0.82, P =0.01) and endoscopic interventions (odds ratio: 0.29, 95% confidence interval: 0.12-0.71, P =0.02) were reported at 5 years post-LVSG relative to LRYGB. Reoperations were more frequently performed for reflux management in LVSG and for internal hernia repairs in LRYGB. Complications requiring medical management were common following both procedures. Limitations included few eligible studies for inclusion, and varying definitions of medically managed complications. CONCLUSIONS: LRYGB is associated with a higher proportion of surgical and endoscopic interventions at 5 years compared with LVSG. More high-quality, long-term studies are required to further elucidate both surgical and nutritional long-term outcomes post these procedures.

OBJECTIVES: To conduct a meta-analysis of randomized controlled trials evaluating the efficacy and drawbacks of limited (D1) versus extended lymphadenectomy (D2) for proven gastric adenocarcinoma. METHODS: A search of Cochrane, Medline, PubMed, Embase, Science Citation Index and Current Contents electronic databases identified randomized controlled trials published in the English language between 1980 and 2008 comparing the outcomes of D1 versus D2 gastrectomy for gastric adenocarcinoma. The meta-analysis was prepared in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses statement. The 6 outcome variables analyzed included length of hospital stay; overall complication rate; anastomotic leak rate; reoperation rate; 30-day mortality rate and 5-year survival rate. Random effects meta-analyses were performed using odds ratios (OR) and weighted mean differences (WMD). RESULTS: Six trials totaling 1876 patients (D1 = 946, D2 = 930) were analyzed. In 5 of the 6 outcomes the summary point estimates favored D1 over D2 group with a statistically significant reduction of (i) 6.37 days reduction in hospital stay (WMD -6.37, confidence interval [CI] -10.66, -2.08, P = 0.0036); (ii) 58% reduction in relative odds of developing postoperative complications (OR 0.42, CI 0.27, 0.66, P = 0.0002); (iii) 60% reduction in anastomotic breakdown (OR 0.40, CI 0.25, 0.63, P = 0.0001); (iv) 67% reduction in reoperation rate (OR 0.33, CI 0.15, 0.72, P = 0.006); and (v) 41% reduction in 30-day mortality rate (OR 0.59, CI 0.40, 0.85, P = 0.0054). Lastly there was no significant difference in the 5-year survival (OR 0.97, CI 0.78, 1.20, P = 0.7662) between D1 and D2 gastrectomy patients. CONCLUSIONS: On the basis of this meta-analysis we conclude that D1 gastrectomy is associated with significant fewer anastomotic leaks, postoperative complication rate, reoperation rate, decreased length of hospital stay and 30-day mortality rate. Finally, the 5-year survival in D1 gastrectomy patients was similar to the D2 cohort.

BACKGROUND: The reuse of enteral tube feeding (ETF) equipment is not recommended due to the risk of microbial contamination and subsequent risk of infection; however, this practice continues in many ambulatory settings. A systematic review of the literature was undertaken to review the evidence underpinning the cleaning and reuse of ETF equipment. METHODS: Studies that investigated the reuse, decontamination, and/or cleaning of ETF equipment were considered for inclusion. Electronic databases were searched (no limits were placed on date of publication, age, or duration of reuse). Extracted data were assessed using Grading of Recommendations, Assessment, Development and Evaluation (GRADE) and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. RESULTS: Ten studies met inclusion criteria: 3 investigated changes to clinical outcomes with extending reuse from 24 to ≤72 hours using water rinses; 5 considered the efficacy of various cleaning methods assessed in laboratory conditions; 2 used a combination of both approaches. Sufficient data to allow GRADE assessment was found only for bottle-type containers. CONCLUSIONS: A very low level of evidence supports the cleaning and reuse of rigid and "unspecified" bottle containers; no studies were found to inform the reuse of syringes used for bolus feeding or any equipment used for water infusion or flushes. There is an absence of literature evaluating the safety and clinical outcomes of cleaning and reusing ETF equipment, and research is required to support equipment reuse.
