Understanding the Best Nutritional Management for Creutzfeldt–Jakob Disease Patients: A Comparison Between East Asian and Western Experiences

(1) Background: Creutzfeldt–Jakob disease (CJD) is a rare and fatal neurodegenerative disorder caused by the accumulation of an altered prion protein, which usually leads to death within one year after clinical onset. CJD patients usually present with rapid cognitive impairment associated with declines in cerebellar, motor, visual, behavioral, and swallowing functions. Moreover, CJD patients lose their ability to eat and take medications orally very early on in treatment; nevertheless, there are no specific nutritional guidelines for this disease shared worldwide. (2) Methods: This review aims to describe the nutritional outcomes of CJD patients in Western countries to compare them with those described in East Asian countries and then aims to explore the most recent trends in the nutritional management of CJD patients, including some dietary compounds that present neuroprotective effects. (3) Results: In Japan’s, Taiwan’s, and China’s healthcare systems, CJD patients receive intensive life-sustaining treatment that prolongs their survival (i.e., artificial feeding); conversely, in Western countries, intensive life-sustaining treatments like tube feeding are not commonly provided to CJD patients. (4) Conclusions: It is difficult to pinpoint the reasons for these discrepancies around CJD palliative care supply, but it is clear that specific nutritional guidelines may directly improve the nutritional management of CJD patients and thus allow their families and caregivers to ensure the best end-of-life care for these patients.

Enhanced Recovery After Surgery (ERAS) Protocol for Craniotomy Patients: A Systematic Review

Context: The enhanced recovery after surgery (ERAS) protocol is a multidisciplinary approach aimed at improving surgical outcomes, reducing complications, minimizing hospital stays, and lowering healthcare costs. Objectives: This study assesses the impact of the ERAS protocol on elective craniotomies, a routine procedure in neurosurgery. Methods: A comprehensive search across PubMed, Embase, Scopus, and Web of Science identified 562 articles. Following strict screening criteria, 54 studies were reviewed, and ultimately 10 studies meeting the inclusion criteria were selected for detailed analysis. Results: The review encompassed ten studies [one prospective, one systematic review, and eight randomized controlled trials (RCTs)] published between 2016 and 2023. Key components of the ERAS protocol included preoperative counseling, high-protein intestinal nutrition, preoperative fasting while avoiding carbohydrate intake within 2 hours of surgery, standardized anesthetic and analgesic regimens, and early postoperative initiation of enteral feeding. Postoperative outcomes showed fewer complications, early mobilization, and notably shorter hospital stays, all of which contributed to improved patient recovery. Conclusions: This review demonstrates that the ERAS protocol, when applied to elective craniotomies, is effective in enhancing postoperative recovery, improving functional outcomes, and reducing hospitalization duration.

Retrospective evaluation of enteral nutrition supplementation in 295 hospitalized dogs and cats (2014-2023).

The goal of this study was to describe clinical and hospital-related factors associated with time to feeding tube placement in hospitalized dogs and cats. This was a retrospective study from January 2014 through December 2023. Medical records at an academic veterinary teaching hospital were reviewed for small animal patients in the ICU with nasogastric or esophageal feeding tube placement for enteral nutrition due to inadequate food intake during hospitalization. Patients with feeding tubes placed prophylactically at hospital admission for surgery or physical inability to eat were excluded. Factors associated with placement including species, disease, inappetence, nutritional plans, and medical record recording of caloric intake were reviewed. 295 patients (89 cats and 206 dogs) were included. Median duration of hospitalization prior to feeding tube placement was 2 days (0 to 17 days) and was shorter in cats. Weekend admission and initial placement of an esophageal tube were associated with increased time to placement. Adequate feeding instructions were provided for only 53 of 295 patients (18%) and associated with both higher likelihood of having caloric intake recorded (OR, 10.30) and earlier feeding tube placement. Provision of enteral nutrition occurred later than recommended by nutritional guidelines in many hospitalized patients. Clinician inclusion of specific diet instructions, weekday admission, and initial nasogastric tube placement reduced this duration. Multiple factors may impact timely provision of nutrition in hospitalized dogs and cats. Close attention to energy requirements and exact food intake should be considered to optimize patient nutritional care.

Multi-Layered Implant Approach for Hemilaryngectomy Reconstruction in a Porcine Model.

Partial laryngectomies result in voice, swallowing, and airway impairment for thousands of patients in the United States each year. Treatment options for dynamic restoration of laryngeal function are limited. Thus, there is a need for new reconstructive approaches. Here, we evaluated early (4 week) outcomes of multi-layered mucosal-myochondral (MMC) implants when used to restore laryngeal form and function after hemilaryngectomy in a porcine model. Six Yucatan minipigs underwent transmural hemilaryngectomies followed by reconstruction with customized MMC implants aiming to provide site-appropriate localization of regenerated laryngeal tissues, while supporting laryngeal function. All implants were fabricated from polymeric collagen, with a subset of muscle and cartilage implants containing motor endplate-expressing muscle progenitor cells or cartilage-like cells differentiated from adipose stem cells, respectively. Vocalization and laryngeal electromyography (L-EMG) measurements with nerve conduction studies were performed post-operatively and compared with baseline along with gross and histological analyses of the healing response. All animals (n = 6) survived and maintained airway patency, safe swallowing, and phonation, without the use of tracheostomy and/or gastrostomy tubes. Histological evaluation indicated no adverse tissue reaction or implant degradation, showing progressive regenerative remodeling with mucosa reformation and ingrowth of new muscle and cartilage. Preliminary L-EMG suggested weak but detectable motor unit action potentials. Although vocalization duration, frequency, and intensity decreased post-operatively, all animals retained vocal capacity and parameter recovery was evident over the study duration. Engineered collagen polymeric implants in the presence or absence of autologous cell populations may serve as a feasible reconstructive option to restore dynamic function after hemilaryngectomy. Long-term follow-up is needed to further assess functional outcomes. NA Laryngoscope, 2024.

Possibility of enteral tube feeding in severe surgical pathology

Objective. To study the possibility of using new GASTROAXILIUM mixtures in complex therapy of patients with severe surgical abdominal pathology. Materials and methods. The study of characteristics of the developed mixtures was carried out by standard and non-standard methods in an accredited laboratory. Clinical studies were conducted in accordance with the Procedure for conducting studies of the effectiveness of specialized dietary therapeutic and dietary preventive food products. Statistical processing was carried out using analysis of variance. Results. GASTROAXILIUM, specialized food product for tube feeding developed by the specialists of the Research and Production Center for Healthy Nutrition Technologies of Saratov State Medical University named after V.I. Razumovsky, differs from foreign ones in its technological solutions. In the main group a statistically significant reduction in the duration of postoperative intestinal paresis was noted, both in planned and emergency surgeries, in contrast to the comparison group. Conclusions. We consider that the results of the use of daily nutritional complex of oligomeric dry mixtures for enteral nutrition GASTROAXILIUM are in agreement with the literature data, they will successfully complement the scientific data on the necessity for nutritional support and will play an important role in improving the quality of treatment of patients with severe postoperative abdominal pathologies.

AHP SO07 - Dietetic Outpatient Service to Patients undergoing Oesophagogastric (OG) Surgery for Cancer

Abstract Background Nutrition is a modifiable risk factor impacting surgical outcomes in OG cancer. Its key role influencing health related quality of life is emerging with improved survivorship. Guidelines depicting optimal timing and type of dietetic intervention for this patient group are unclear. In order to best direct dietetic care, optimise timing of nutritional interventions and understand demand for service it is important to reflect on current provision. This audit aimed to describe the dietetic outpatient service to patients undergoing OG Surgery for cancer in a national centre for treatment of oesophageal cancer. Method A retrospective review of dietetic records and statistics. Patients who underwent oesophagectomy (O), gastrectomy (G) or subtotal gastrectomy (STG) for cancer between May 2022- May 2023 were included. Results 63 patients were included: 38 O, 17 TG, 8 STG. 11 were seen by the dietitian at first visit to OG Clinic (9 O, 1 TG, 1 STG) – 6 had an elective feeding tube (FT) inserted for neoadjuvant treatment (5 O, 1 STG). 83% attended a surgical pre-assessment dietetic appointment (36 O, 14 TG, 2 STG). 86% were reviewed within 1 month post O or TG, 75% post STG. 258 dietetic interventions occurred in the first year post-op (median 3.5, range 0-14). 64% in the first 3 months(m) post op, 16% at 3-6m, 10% at 6-9m, 10% at 9-12m. Conclusion In this high nutritional risk group only 18% are assessed by a dietitian at first visit to UGI MDT clinic. There is a successful pathway for immediate peri-operative dietetic care in patients post O and TG. The pathway for STG is less well established. Dietetic interventions are concentrated in the first 3 months after surgery. There is no established protocol to support longer term nutritional needs into survivorship. To inform practice a measure of patient experience and needs would be useful, to explore best delivery format and access routes to future services.

AHP SO06 - A case report of the nutritional and multi-disciplinary team (MDT) management of an emergency oesophageal perforation associated with Eosinophilic Oesophagitis (EOE)

Abstract Background EOE once considered rare, is a chronic inflammatory condition of the oesophagus presenting as dysphagia and food impaction in children and adults. Awareness and management of EOE is variable despite an increasing prevalence and the condition deemed the most common cause of oesophageal perforation in adults and children by the British Society of Gastroenterology (BSG). This case review aims to increase the awareness of EOE, highlight the clinical presentation of EOE, discuss considerations for the nutritional management and the importance of an MDT approach to the care of this condition in relation to the BSG consensus guidelines. Method The patient was admitted to a specialist oesophago-gastric surgical centre in the Northwest of England. A retrospective review of the patient’s case notes was completed. This included exploration of all inpatient and outpatient contacts stored in the electronic patient records system. Results 18-year-old underweight male with IgE-mediated nut allergy and odynophagia, developed complex multi-site oesophageal perforations following OGD. Management included 40-day endoluminal vacuum therapy and extensive nutritional support. Although initial biopsies lacked diagnostic quality and conclusive results, EOE was subsequently confirmed. Dietetic evaluation included nutritional status, atopic history, symptoms, and dietary intolerances. MDT discussions influenced care continuity and patient compliance. Feeding delays attributable to frequent theatre visits impacted continued weight loss; addressed with allergen-free enteral and parenteral feeding, and dietary reintroduction, following six-food elimination once perforations had healed. Healthy BMI was achieved through patient’s preferred long-term management of normal diet and Budesonide. Conclusion Increased awareness of EOE is paramount for patients presenting with unexplained oesophageal perforation. Obtaining biopsy samples as per BSG guidance supports earlier diagnosis and management plan. A thorough clinical history including childhood eating behaviours, atopic history, dietary intolerances and symptom presentation from the patient and relatives gathers collateral information to support diagnosis and treatment planning. Joint discussions regarding pharmaceutical management, dietary elimination and reintroduction are important to achieve remission. The case highlights the importance of collaborative MDT working with the surgical, medical and dietetics whilst empowering the patient to make informed decisions regarding the nutritional and medical management of condition.

BN SO54 - Complex Management of a Gastrocutaneous Fistula Following Pancreatic Necrosectomy: A Case Report

Abstract Background Gastrocutaneous fistulas are rare but serious complications that can arise following the surgical treatment of necrotizing pancreatitis. This post-operatory complication can be refractory to conservative management and may be further aggravated by severe skin injuries and malnutrition. This case report describes the comprehensive and multidisciplinary approach of a challenging case of gastrocutaneous fistula, ultimately requiring re-intervention. Method A 78-year-old female with a history of severe necrotizing pancreatitis underwent pancreatic necrosectomy by laparotomy. Postoperatively, she developed a gastric fistula, initially repaired with a double-layered suture. Recurrence led to a gastrocutaneous fistula with continuous gastric drainage and chemical burn of the surrounding skin. Initial conservative management included insertion of a nasogastric tube for gastric decompression, followed by placement of a PEG tube to redirect the drainage and prevent further skin damage and an esophagojejunal feeding tube to bypass the fistula and maintain nutrition. Nevertheless, the fistula persisted, resulting in significant skin erosion and deterioration of the patient’s condition. Results Given the failure of conservative measures and a concurrent diagnosis of a pancreatic fistula, a surgical approach was deemed necessary. The patient was transferred to a specialized hospital center, where she underwent fistulectomy with partial gastrectomy and wound closure. Negative pressure wound therapy (NPWT) was applied to the ulcerated skin to promote healing. This approach led to the successful closure of the gastrocutaneous fistula and healing of the skin wound. The patient showed marked clinical recovery, with no signs of infection or fistula recurrence and the nutritional status was successfully managed through enteral feeding leading to a notable functional recovery. Conclusion This case underlines the complexity of managing gastrocutaneous fistulas, demonstrating the efficacy of combining surgical and supportive therapies, serving as a reference for similar future cases and emphasizing the need for comprehensive management strategies for complex postoperative complications.

HPB O05 - Changing paradigms in the management of severe acute pancreatitis: Focused multi-disciplinary working between surgeons and intensivists to mitigate organ failure in order to reduce mortality

Abstract Background Mortality was classically bimodal in severe acute pancreatitis and organ failure is the single most important factor in predicting outcome in severe acute pancreatitis. Initial interventions are supportive often requiring critical care. Subsequently treatments are required to manage necrosis and any organ recovery remains under threat. The outcomes and interventions from surgery and critical care are reviewed to determine how to balance organ failure and the need for necrosectomy in a modern multi-disciplinary tertiary care centre Method The Royal Liverpool provides a tertiary service to all patients with pancreatitis across Merseyside and North Wales. All patients that were transferred to critical care from 2018 – 2023 were analysed using the intensive care national audit and research centre database which contains information on organ failure. The patients with severe pancreatitis were then reviewed using electronic clinical notes and radiology images to determine clinical course and management. Results Of 134 patients, 48 (36%) were admitted locally, 85 (64%) transferred in, occurring 35% <2weeks, 29% 2-4weeks, 28% 4-6weeks and 8% >8weeks. 76 (57%) required necrosis intervention, 58 (43%) were conservatively managed. Mortality was 38% with 35% <4weeks, 22% 4-8weeks, 22% 8-12weeks, 22% >12weeks. No significant difference in mortality between conservative or interventional management (15 (45%) vs 18 (55%)) nor median age (58 vs 57.5 yrs). Survival related to number of failing organs (dead vs alive): nil organs: 10 patients vs 27 patients (20%vs32%), One: 11 vs 45 (22%vs45%), Two: 21 vs 9 (42%vs11%), Three: 8 vs 3 (16%vs4%), p<0.005. Conclusion Of patients deemed fit for ITU admission with necrotising pancreatitis, the classic paradigms of biphasic mortality no longer occur. Differences in mortality from intervention and age of patient has been negated by optimal ITU management for organ failure. For the initial phases and the intervention phases of management, ensuring degree of organ failure is key to survival. There is a significant change when two organs fail in mortality and this stresses the importance of holistic management. Our ITU promotes pancreas specific organ preservation measures of early enteral feeding, cessation/tailoring of antibiotics, early extubation/tracheostomy and most importantly multidisciplinary working

Impact of Interhospital Transfer on Outcomes in Acute Pancreatitis: Implications for Healthcare Quality

Background/Objectives: Effective management of acute pancreatitis (AP) hinges on prompt volume resuscitation and is adversely affected by delays in diagnosis. Given diverse clinical settings (tertiary care vs. community hospitals), further investigation is needed to understand the impact of the initial setting to which patients presented on clinical outcomes and quality of care. This study aimed to compare outcomes and quality indicators between AP patients who first presented to the emergency department (ED) of a tertiary care center and AP patients transferred from community hospitals. Methods: This study included AP patients managed at our tertiary care hospital between 2008 and 2018. We compared demographics and outcomes, including length of stay (LOS), intensive care unit (ICU) admission, rates of local and systemic complications, re-admission rates, and one-year mortality in transferred patients and those admitted from the ED. Quality indicators of interest included duration of volume resuscitation, time until advancement to enteral feeding, pain requiring opioid medication [measured in morphine milliequivalent (MME) dosing], and surgical referrals for cholecystectomy. Categorical variables were analyzed by chi-square or Fisher’s exact test; continuous variables were compared using Kruskal–Wallis tests. Regression was performed to assess the impact of transfer status on our outcomes of interest. Results: Our cohort of 882 AP patients comprised 648 patients admitted from the ED and 234 patients transferred from a community hospital. Transferred patients were older (54.6 vs. 51.0 years old, p < 0.01) and had less frequent alcohol use (28% vs. 39%, p < 0.01). Transferred patients had a significantly greater frequency of gallstone AP (40% vs. 23%), but a lower frequency of alcohol AP (16% vs. 22%) and idiopathic AP (29% vs. 41%) (p < 0.001). Regarding clinical outcomes, transferred patients had significantly higher rates of severe AP (revised Atlanta classification) (10% vs. 2% severe, p < 0.001) and ICU admission (8% vs. 2%, p < 0.001) and longer median LOS (5 vs. 4 days, p < 0.001). Regarding quality indicators, there was no significant difference in the number of days of intravenous fluid administration, or days until advancement to enteral feeding, pain requiring opioid pain medication, or rates of surgical referral for cholecystectomy. Conclusions: Though the quality of care was similar in both groups, transferred patients had more severe AP with higher rates of systemic complications and ICU admissions and longer LOS, with no difference in quality indicators between groups.

CHEN Yinglong's ziwu reinforcing and reducing acupuncture method for post-stroke swallowing dysfunction in the pharyngeal phase: a randomized controlled trial

To observe the clinical effect of CHEN Yinglong 's ziwu reinforcing and reducing acupuncture method on post-stroke swallowing dysfunction (PSD) in the pharyngeal phase, and explore its biomechanical mechanism. A total of 72 patients with PSD in the pharyngeal phase were randomly divided into a ziwu reinforcing and reducing acupuncture group (36 cases, 2 cases dropped out and 1 case was eliminated) and a conventional acupuncture group (36 cases, 1 case dropped out and 1 case was eliminated). The patients in the conventional acupuncture group were treated with conventional acupuncture at Lianquan (CV 23) and bilateral Fengchi (GB 20), Wangu (GB 12), Tongli (HT 5), Zhaohai (KI 6), Hegu (LI 4), Taichong (LR 3). The patients in the ziwu reinforcing and reducing acupuncture group were treated with CHEN Yinglong 's ziwu reinforcing and reducing acupuncture method on the basis of the conventional acupuncture group's acupoints. Both groups were treated with acupuncture for 30 min each time, once a day, and rested for 1 day after 6 days of treatment, and the treatment lasted 4 weeks. Before and after treatment, the standardized swallowing assessment (SSA) score, Rosenbek penetration aspiration scale (PAS) grade, the shortening rate of mandibular-hyoid distance, swallowing quality of life (SWAL-QOL) score were evaluated in the two groups. The removal rate of nasogastric feeding tube was compared in the two groups, and the clinical efficacy and safety of the two groups were compared. After treatment, the SSA scores and PAS grade of the two groups were lower than those before treatment (P<0.001), and above indexes in the ziwu reinforcing and reducing acupuncture group were lower than those in the conventional acupuncture group (P<0.01, P<0.05). After treatment, the shortening rates of mandibular-hyoid distance and SWAL-QOL scores in the two groups were higher than those before treatment (P<0.001), and the shortening rate of mandibular-hyoid distance in the ziwu reinforcing and reducing acupuncture group was higher than that in the conventional acupuncture group (P<0.001). The removal rate of nasogastric feeding tube in the ziwu reinforcing and reducing acupuncture group was 87.9% (29/33), which was higher than 61.8% (21/34) in the conventional acupuncture group (P<0.05). The total effective rate of the ziwu reinforcing and reducing acupuncture group was 84.8% (28/33), which was higher than 61.8% (21/34) of the conventional acupuncture group (P<0.05). Neither group experienced serious adverse reactions. CHEN Yinglong 's ziwu reinforcing and reducing acupuncture method can effectively improve swallowing dysfunction in the pharyngeal phase after stroke, reduce the risk of aspiration, and improve quality of life. Its therapeutic effect may be related to increasing the displacement amplitude of the hyoid bone.

Correlation of preoperative CT features with intra- and postoperative parameters of endoscopic resection in patients with gastric submucosal tumor (1~3cm).

Endoscopic resection of gastric submucosal tumors (SMTs) possesses minimal trauma, expedited recovery, and reduced costs. Nonetheless, intraoperative challenges, including imprecise surgical risk assessment, prevail. Hence, we investigated the correlation between preoperative CT observation features and perioperative parameters for predicting outcomes in SMT patients. Subjects diagnosed with SMT and undergoing endoscopic surgery conducted at West China Hospital's Endoscopy Center from September 2019 to October 2023 were retrospectively selected. Endoscopic ultrasonography (EUS) and computer tomography (CT) were utilized for evaluating SMT. The study assessed the correlation between preoperative CT findings and perioperative parameters. Increased lesion size on contrast-enhanced CT correlates with increased operative duration, hospital stay, postoperative antibiotic use. Of utmost significance, we observed a significantly higher intraoperative perforation rate for patients with tumor outgrowth compared to those with lesion involvement of the lumen (96.88% vs 29.11%, P < 0.001). These patients also demonstrated an increased risk of postoperative blood stream infections (P = 0.012), necessitating higher antibiotic grade (P = 0.048), along with prolonged gastrostomy tube retention (P = 0.001) and hospitalization (P = 0.018). In addition, CT provides a more accurate and comprehensive assessment of tumor size (P = 0.037) and growth pattern (P = 0.026) than EUS. CT assessment of tumor size closer to reality than EUS. Importantly, these features can assist in pinpointing lesions with elevated surgical complexity and high risk of complications, leading to improved preoperative preparation, thereby increasing anticipation of surgical risks and reducing incidence of complications.

Esophageal perforation in premature newborns

BACKGROUND: Esophageal perforation is a rare entity in newborns. This condition is most common in premature babies with very low and extremely low birth weight. The major cause of such pathology is considered to be iatrogenic trauma of either pharynx or esophagus, their soft tissues being delicate and tender enough to produce delamination and perforation of their wall. As a rule, this occurs as a complication of either a difficult tracheal intubation soon after birth or during some troubles with oro- or nasogastric tube insertion. AIM: To analyze our experience of revealing and treatment of esophageal perforation in preterm babies, and to demonstrate conservative approach as a possible as well as reasonable option in such cases. METHODS: A retrospective study of neonatal esophageal perforation cases was performed, including newborns without any congenital esophageal malformations or previous surgical procedures. During 2017–2022 9 newborns with esophageal perforation were treated at neonatal intensive care unit and neonatal departments of Childrens’ City Multidisciplinary Clinical Specialized Center of High Medical Technologies of Saint Petersburg. All of them were premature, 2 having very low, and 7 having extremely low birth weight. The incidence of that condition appeared to be 1:1320 live births. RESULTS: 8 patients were treated conservatively. This included adjustment of artificial lung ventilation, pain control, antibiotics, cancellation of gastric enteral feeding and administration of total parenteral nutrition. Babies with hydrothorax, pneumothorax or ascites underwent thoraco- or laparocentesis. 2 patients died, both being born at 23th week of gestation. In both cases death occurred from polyorganic insufficiency. The mortality rate appeared to be 22%. CONCLUSION: In most cases the esophageal perforation in premature babies can be treated conservatively, the efficacy of such treatment being largely dependent on early diagnosis of this complication. An important key-point in it is a radiologic control of gastric tube location.

Dumping syndrome: Update on pathophysiology, diagnosis, and management.

Dumping syndrome is a complex of gastrointestinal symptoms originally studied in peptic ulcer surgery patients. At present, it is most prevalent in patients who underwent bariatric, upper gastrointestinal cancer or anti-reflux surgery. The symptom pattern comprises early and late dumping symptoms. Several management options have been reported including nutritional, pharmacological and surgical approaches. In this study, we aimed to review the current evidence on dumping syndrome definition, diagnosis and treatment, including preliminary data from newer pharmacological studies. Current pathophysiological concepts and analyses of provocative tests has led to a clear definition of dumping syndrome, including both early and late dumping symptoms. The term postbariatric hypoglycemia represents a limited focus on late dumping only. The diagnosis relies on recognition of symptoms and signs in a patient with appropriate surgical history; and can be confirmed by provocative testing or registration of spontaneous hypoglycemia. The initial treatment focuses on dietary intervention, to which meal viscosity enhancers and/or the glycosidase inhibitor acarbose can be added. The most effective therapy is the use of short- or long-acting somatostatin analogues, which is however expensive and entails side effect issues. In case of refractory hypoglycemia, diazoxide or SGLT2 inhibitors can be considered, based on limited evidence. In refractory patients, continuous enteral feeding or (rarely) surgical reinterventions have been advocated, although not supported by solid evidence. Therapies under current evaluation include the broad-spectrum somatostatin analogue pasireotide, GLP-1 receptor antagonists, GLP-1 receptor agonists and administration of stable forms of glucagon are currently under study. Dumping syndrome is a well-defined but probably under-diagnosed complication of upper gastrointestinal, especially bariatric, and surgeries. Diagnosis is confirmed by a provocative test and incremental therapies starting with diet, adding meal viscosity enhancers or glycosidase inhibitors and adding somatostatin analogues in refractory cases. A number of emerging therapies targeting intestinal propulsion, peptide hormone effects and hypoglycemic events are under evaluation.

Comparison of enteral prucalopride versus intravenous metoclopramide for feeding intolerance in patients with critical illness: a randomized double-blinded study

BackgroundFeeding intolerance is commonly experienced during enteral feeding, necessitating cessation. Metoclopramide may be given to assist gastric emptying, but patients experience adverse effects and gradual loss of efficacy. Prucalopride, a safer prokinetic, may play a role in gastric emptying. Therefore, the current study aimed to assess its effectiveness and safety in feeding intolerance developed in critically ill patients.Materials and MethodsIn this prospective randomized double-blinded study, patients with feeding intolerance were randomized to receive 2 mg prucalopride enterally once daily or 10 mg metoclopramide intravenously every 6–8 h for 7 days. Patients were monitored for treatment failure, successful feeding, gastric residual volume (GRV), and the development of medication-related adverse effects.ResultsA total of 70 patients (35 in the metoclopramide group and 35 in the prucalopride group) completed the study. The average daily GRV in the prucalopride group was significantly lower compared to the metoclopramide group (p=&amp;lt;0.001) on day 7. Additionally, the percentage change in GRV from day 1 to day 7 showed a greater significant change in the prucalopride arm versus the metoclopramide arm (p=&amp;lt;0.001). The treatment groups were comparable in terms of ICU length of stay (p = 0.094). Moreover, there was a significantly higher successful caloric intake in the prucalopride group compared to the metoclopramide group on day 7 (p = 0.039).ConclusionPrucalopride administration in enterally fed patients with feeding intolerance may reduce GRV and improve feeding success rates compared to metoclopramide treatment. The use of prucalopride was found to be tolerable and safe in critically ill patients.Clinical Trial Registrationclinicaltrials.gov, identifier NCT05496179

Dolutegravir with enteral feeds in intensive care: nutrition vs viral suppression

Abstract Introduction People living with HIV requiring admission to intensive care often receive enteral nutrition via feeding tubes. Enteral feeds contain cations which may interfere with dolutegravir (DTG) absorption due to chelation1. For this reason, temporal spacing (six hours before/ two hours after DTG administration2) is recommended, possibly leading to suboptimal caloric intake3. The clinical significance of the interaction between enteral feeds and DTG when co-administered is not fully understood and public data are sparse. Aim We aim to evaluate the impact and outcomes of co-administering DTG and enteral feeds. Methods Review of prospectively collected data on therapeutic drug monitoring (TDM) and electronic patient records of patients on DTG and enteral feeds, whilst in intensive care unit (ITU) between 2022 and 2023. Maximum (Cmax) and trough (Ctrough) DTG concentrations were measured and compared to reference ranges (DTG 50 mg once daily: Cmax 3340 ng/mL; Ctrough 830 ng/mL). All data were anonymised and collected as part of routine care for analysis. According to the National Research Ethics Service guidelines, further patient consent and ethical approval were not required. Results Six cases were identified with eight incidences of TDM sampling: 2 (33%) female; median age 34 (IQR 33-42); 3 (50%) non-white ethnicity; mean number of days on ITU 46 days; mean number of days into feeds 28 days; all (100%) suffered from hypoalbuminaemia (18-26 g/L). All patients were taking tenofovir-based regimens as their backbone antiretroviral therapy and once daily DTG, unless when co-administered with rifampicin where twice daily DTG is required to overcome enzyme induction effects of rifampicin. In three of the eight samples, temporal spacing with enteral feeds occurred as per SPC guidance2. The highest Cmax with once daily DTG seen in this cohort was 2201 ng/mL which was achieved without temporal spacing, whilst the lowest Ctrough (44 ng/mL) was observed in a different individual with sufficient temporal spacing. The viral loads measured while patients were receiving feeds varied, with 3 (50%) remaining suppressed. All (100%) patients had a fully suppressed viral load after enteral feeds ceased, including one patient who was naïve to treatment prior to admission with a high viral load. Discussion/Conclusion DTG Cmax were lower than those observed in literature regardless of temporal spacing from enteral feeds. Ctrough concentrations were also lower than expected in all cases. Six of eight Ctrough were lower than the DTG minimum effective concentration (MEC) of 300 ng/mL, however, only one was below IC90 for wildtype virus (64 ng/mL). Virological failure or onset of resistance was not observed in any of the patients. Multiple factors are likely to be contributing to low DTG concentrations, of which the most significant is likely impaired drug absorption, whilst nutritional feed co-administration seems to not be relevant.

Early Adequate Nutrition in ICU is Associated with Survival Gain : Retrospective Cohort Study in Patient with Traumatic Brain Injury.

Patients with traumatic brain injury (TBI) commonly exhibit a poor mental health status and can easily develop aspiration pneumonia. Thus, early proper nutrition through oral or tube feeding is difficult to achieve, leading to malnutrition. However, evidence regarding early nutritional support in the intensive care unit (ICU) is lacking. We aimed to assess the effect of early nutrition in patients with TBI admitted to the ICU. Data of adult patients with TBI admitted to the trauma ICU of a regional trauma center in Korea between 2022 and 2023 were retrospectively analyzed. Those with ICU stay <7 days, younger than 18 years, and with underlying diseases that could alter baseline metabolism, were excluded. Nutritional support on day 4 of ICU admission was measured. The patients were classified into mortality and survival groups, and risk factors for mortality were evaluated. Subgroup analyses were performed based on TBI severity. Overall, 864 patients were diagnosed with acute TBI, of whom 227 were included in this study. The mortality rate in the study population was 15% (n=34). Those in the survival group were younger, had longer hospital stays, had a higher initial Glasglow Coma Scale (GCS) score, and had a higher intake of calorie supplements than those in the mortality group. In a subgroup analysis of patients with non-severe TBI (GCS>8), total calorie intake (751.4 vs 434.2 kcal, p=0.029), total protein intake (37.5 vs. 22.1 g, p=0.045), and ratio of supplied to target calories (0.49 vs 0.30, p=0.047) were higher in the survival group than in the mortality group. Logistic regression analysis revealed that calorie intake (B=-0.002, p=0.040) and initial hemoglobin level (B=-0.394, p=0.005) were risk factors for mortality in patients with non-severe TBI. More calories were supplied to the survival group than the mortality group among patients with TBI. Additionally, logistic regression analysis showed that increased calorie supply was associated with reduced mortality in patients with non-severe TBI. The mortality group had low protein intake; however, this did not emerge as a risk factor for mortality. Early sufficient nutritional support improves the prognosis of patients with TBI.

Vascular Labeling of Extracranial Head and Neck Vessels Using Silicone Dye Injection: An Effective Method for Cadaver-Based Facial Surgery Training

Abstract Background Silicone dye injection is a well-described technique for studying vascular anatomy. Plastic surgeons routinely participate in cadaveric workshops and are involved in the preparation of vascular-labeled cadavers. However, sparse literature is available on dye studies of extracranial head and neck vessels, even with anatomists, and the preparation of these cadavers is a daunting task. Materials and Methods In this study, we describe a straightforward technique of silicone dye injection for extracranial head and neck vasculature and its application for filler injection training and other plastic surgical procedure demonstrations on cadavers. We used six soft-embalmed cadavers. The common carotid arteries and internal jugular veins were cannulated with infant feeding tubes. The vessels that could lead to dye extravasation into intracranial vessels and upper limbs were ligated. The vasculature was irrigated with water and then injected with color-coded silicone dyes (red: arterial; blue: venous). The solvent-to-catalyst ratios were varied to identify the ideal combination. Injected specimens were dissected 24 hours later to identify the staining quality. Results A clear demarcation of the extracranial head and neck vasculature in all cadavers was seen. The best solvent-to-catalyst ratio was identified in cadavers with the best staining of both large and small-sized blood vessels (&lt;1 mm) with no dye spillage from arteries to the veins. Conclusion Silicone dye injection with the described technique can give excellent and predictable results. The technique also uses less quantity of dye, and the intracranial structures are spared, which can be used for other studies; hence, there is more economical utilization of cadavers.

Effects of rapid enteral feed advancement with early human milk fortification in very low birth weight preterm infants > 30 weeks gestation in a resource limited setting- a randomized controlled trial.

To study the effects of rapid enteral feed advancement with early feed fortification in stable very low birth weight (VLBW) infants >30 weeks gestation. Preterm infants (N = 92) were randomized to a) rapid feed advancement-early fortification - REF group (enteral feed advanced at 25-30 ml/kg/day, fortification at 50 ml/kg/day) or b) slow feed advancement-late fortification-SLF group (feed advanced at 15-20 ml/kg/day, fortification at 100 ml/kg/day). The primary outcome-time to regain birth weight was significantly lower in REF group (9 days vs 13 days, P = 0.02). REF group reached full enteral feeds earlier (6 days vs 9 days, P = 0.001), had lower rates of sepsis (13% vs 38%, P = 0.007) and shorter hospital stay (10 days vs 15 days, P = 0.01). At one year, the median Z-scores for weight [-1.5 vs -2.2, P < 0.001] and head circumference [1.1 vs 0, P < 0.001) were significantly higher in the REF group. In VLBW preterm infants >30 weeks, rapid feed advancement with early fortification resulted in early postnatal regain of birth weight with positive effects on growth at one year.
