RESUMEN
PURPOSE OF REVIEW: Enteral feeding is commonly used to provide patients with nutrition. Access via feeding tubes can be attained by multiple medical specialties through a variety of methods. RECENT FINDINGS: There are limited data available on direct comparisons amongst gastroenterologist, interventional radiologists and surgeons, although there appears to be similar rates of complications. Fluroscopically and surgically placed feeding tubes may have a higher technical success rate than endoscopically placed tubes. The preferred specialty for feeding tube placement varies per institution, often due to logistical matters over technique or concern for complications. Ideally, a multidisciplinary team should exist to determine which approach is best in a patient-specific manner.

PURPOSE OF REVIEW: Provide an evidence-based resource to inform ethically sound recommendations regarding end of life nutrition therapy. RECENT FINDINGS: ⢠Some patients with a reasonable performance status can temporarily benefit from medically administered nutrition and hydration(MANH) at the end of life. ⢠MANH is contraindicated in advanced dementia. ⢠MANH eventually becomes nonbeneficial or harmful in terms of survival, function, and comfort for all patients at end of life. ⢠Shared decision-making is a practice based on relational autonomy, and the ethical gold standard in end of life decisions. A treatment should be offered if there is expectation of benefit, but clinicians are not obligated to offer non-beneficial treatments. A decision to proceed or not should be based on the patient's values and preferences, a discussion of all potential outcomes, prognosis for given outcomes taking into consideration disease trajectory and functional status, and physician guidance provided in the form of a recommendation.

BACKGROUND AND AIMS: ERCP is challenging in patients with Roux-en-Y gastric bypass (RYGB) anatomy. EUS-guided gastrogastrostomy (GG) creation is a promising novel technique to access the excluded stomach to facilitate conventional ERCP. We aimed to compare procedural outcomes and adverse events (AEs) between EUS-guided GG-assisted ERCP (EUS-GG-ERCP) and enteroscopy-assisted ERCP (e-ERCP) in patients with RYGB. METHODS: Patients with RYGB anatomy who underwent EUS-GG-ERCP or e-ERCP between 2014 and 2016 at 5 tertiary centers were included. The primary outcome was technical success of ERCP, defined as successful cannulation of the selected duct with successful intervention as intended. Secondary outcomes included total procedural time (in the EUS-GG group, total procedural time included EUS-GG creation plus ERCP procedure time), length of hospital stay, and rate/severity of AEs graded according to the American Society for Gastrointestinal Endoscopy lexicon. RESULTS: A total of 60 patients (mean age, 57.2 ± 13.2; 75% women) were included, of whom 30 (50%) underwent EUS-GG-ERCP and 30 (50%) underwent e-ERCP (double-balloon enteroscope ERCP, 19; single-balloon enteroscope ERCP, 11). The technical success rate was significantly higher in the EUS-GG-ERCP versus the e-ERCP group (100% vs 60.0%, P < .001). Total procedure time was significantly shorter in patients who underwent EUS-GG-ERCP (49.8 minutes vs 90.7 minutes, P < .001). Postprocedure median length of hospitalization was shorter in the EUS-GG group (1 vs 10.5 days, P = .02). Rate of AEs was similar in both groups (10% vs 6.7%, P = 1). CONCLUSIONS: EUS-GG-ERCP may be superior to e-ERCP in patients with RYGB anatomy in terms of a higher technical success and shorter procedural times and offers a similar safety profile.

Tuberculous meningitis presents a diagnostic and therapeutic challenge, and considering its long history and increasing global incidence, the evidence base for its treatment is relatively scanty. Many UK neurologists will have little first-hand experience of this deadly condition, and if faced with a patient with possible tuberculous meningitis will find decision making less than straightforward. In parts of East London (UK) the rates of tuberculosis and tuberculous meningitis are among the highest in Western Europe, and so the neurologists and respiratory physicians at the Royal London Hospital have encountered many such patients over the years. We have found experience to be a valuable teacher and so would like to share five cases that illustrate the complexities of diagnosis and management of the disease, and complications of its treatment.

BACKGROUND AND AIM: Osteopontin (OPN) is a phosphoprotein that activates pathways that induce cancer cell survival and metastasis. Our aim was to examine the expression pattern of OPN splice variants a, b, and c in fine-needle aspirates and to determine their correlation with stage-adjusted pancreatic ductal adenocarcinoma (PDA) survival. METHODS: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed in patients with solid pancreatic masses. The tissue was collected and analyzed for the expression of OPN isoforms by reverse transcription-polymerase chain reaction. Survival curves of stages and overexpression of OPN splice variants (a, b, c) were estimated according to the Kaplan-Meier and the log-rank test. RESULTS: EUS-FNA was performed in 46 patients with solid pancreatic lesions (40 PDA and 6 chronic pancreatitis). OPNa was highly expressed in 39/40 (98%), OPNb in 24/40 (60%), while OPNc was present in 10/40 (25%) of PDA samples. The median survival was lower in patients whose fine-needle aspiration (FNA) samples expressed OPNb than those without (406 days vs 749 days, P = 0.049). There was no significant difference in survival in patients with OPNc. Cox proportional hazard model demonstrated that OPNb expression had a trend toward decrease overall survival (P = 0.06), with these patients having a hazard of death three times higher than those without. OPNc was found to significantly correlate with metastatic disease (P = 0.009) in PDA patients. CONCLUSIONS: Our data show for the first time that in FNA samples, there is a strong association between OPNc and presence of metastasis in PDA, and OPNb and poor survival.

Background: The study aimed to elucidate the prevalence of nitrous oxide (N2O) usage in patients with unexplained venous thromboembolism (VTE), highlighting the potential association with hyperhomocysteinaemia (HHcy). Methods: We conducted a retrospective study at the Royal London Hospital, examining cases of N2O-related VTE from March to August 2023. Among 50 patients identified, four (8%) had recent unprovoked VTE. Patient data were collected based on N2O ambulatory emergency care pathway admissions. Results: Among the 50 patients identified, four (8%) had recent or concurrent VTE. Three were male (75%), with an ethnic distribution of 50% Asian or Asian British and 50% Black or Black British. Patients were distributed across quintiles of the index of multiple deprivation. All had actual or functional vitamin B12 deficiency. Discussion: The association between N2O use and VTE requires further investigation, though a plausible mechanism involving HHcy has been proposed. Clinicians should be vigilant for VTE in N2O users, especially those presenting with unexplained symptoms. VTE prophylaxis may be worth considering, particularly if continued exposure to nitrous oxide is anticipated. Conclusion: N2O misuse may increase the risk of VTE, warranting attention from healthcare providers. Further research is needed to elucidate this association and inform preventive strategies. Public awareness about the risks of N2O remains essential.
RESUMEN
PURPOSE OF REVIEW: Nonalcoholic fatty liver disease (NAFLD) is widely prevalent in the U.S and is the primary cause of chronic liver disease. Existing evidence shows that food insecurity may be an independent risk factor for fatty liver disease and is associated with poor health outcomes. Understanding the role of food insecurity in these patients can help develop mitigation strategies to address the growing prevalence of NAFLD. RECENT FINDINGS: Food insecurity is associated with increased overall mortality and health care utilization among patients with NAFLD and advanced fibrosis. Individuals from low-income households with diabetes and obesity are particularly susceptible. Trends in prevalence of NAFLD mirror that of obesity and other cardiometabolic risk factors. Several studies in both adult and adolescent population have described an independent association between food insecurity and NAFLD. Concentrated efforts to lessen food insecurity may improve health outcomes in this group of patients. High-risk patients with NAFLD should be linked with local and federal supplemental food assistance programs. Programs directed at addressing NAFLD-related mortality and morbidity should focus on improving food quality, access to these foods, and promote healthy eating habits.

PURPOSE OF THE REVIEW: The field of nutrition is in debt to a cadre of women who led the field through its formative years. This review highlights the contributions of these women that are gleaned through analysis of biographical articles published in The Journal of Nutrition. RECENT FINDINGS: Forces emerged during the development of nutrition science, such as departments of home economics and the majority-female field of dietetics, that suggest women might be well represented in biographical articles in the field of nutrition. However, just 29 women have been the subject of biographical articles in The Journal of Nutrition representing 14.3% of the 202 biographical articles published to date - a percentage lower than scientific journals overall. This review explores these biographies to identify factors that facilitated and hindered careers and to highlight the manifold scientific contributions of women in nutrition science. This review looks toward the past to provide perspective and inspiration for those working in the field of nutrition today.

Cardiovascular disease (CVD) is considered to be one of the most epidemic diseases in the world today. Predicting CVDs, such as cardiac arrest, is a difficult task in the area of healthcare. The healthcare industry has a vast collection of datasets for analysis and prediction purposes. Somehow, the predictions made on these publicly available datasets may be erroneous. To make the prediction accurate, real-time data need to be collected. This study collected real-time data using sensors and stored it on a cloud computing platform, such as Google Firebase. The acquired data is then classified using six machine-learning algorithms: Artificial Neural Network (ANN), Random Forest Classifier (RFC), Gradient Boost Extreme Gradient Boosting (XGBoost) classifier, Support Vector Machine (SVM), Naïve Bayes (NB), and Decision Tree (DT). Furthermore, we have presented two novel gender-based risk classification and age-wise risk classification approach in the undertaken study. The presented approaches have used Kaplan-Meier and Cox regression survival analysis methodologies for risk detection and classification. The presented approaches also assist health experts in identifying the risk probability risk and the 10-year risk score prediction. The proposed system is an economical alternative to the existing system due to its low cost. The outcome obtained shows an enhanced level of performance with an overall accuracy of 98% using DT on our collected dataset for cardiac risk prediction. We also introduced two risk classification models for gender- and age-wise people to detect their survival probability. The outcome of the proposed model shows accurate probability in both classes.

OBJECTIVES: Non-celiac gluten sensitivity (NCGS) is the presence of symptoms induced by gluten and relieved by a gluten-free diet (GFD) in patients without celiac disease or wheat allergy. Studies are mixed as to whether gluten is the main symptom trigger in patients with NCGS. Gluten immunogenic peptides (GIPs) in stool and urine are novel methods to monitor GFD compliance. Few studies have investigated their use in patients with NCGS. The aim of this study was to assess whether patients with NCGS have increased symptoms with gluten ingestion and to assess compliance with the GFD using stool and urine GIPs. METHOD: This was a prospective, randomized, double-blinded crossover trial evaluating symptoms in patients with NCGS. Thirty patients with NCGS and 43 healthy controls were placed on a GFD. Patients received 0.5 or 2 g/d of gluten for 7 d each. The remaining weeks, they received placebo for a total of 4 wk. Symptoms were evaluated weekly using the Celiac Symptom Index (CSI). Urine and stool samples were collected weekly and measured for the detection of GIPs to detect exposure to gluten. RESULTS: There was no difference in symptom severity within the NCGS group whether receiving placebo or gluten (32.69 versus 31.54, P = 0.64). Patients with NCGS had significantly higher CSI scores at baseline than healthy controls. Patients with NCGS were less likely to have stool and urine GIPs than healthy patients. CONCLUSION: Patients with NCGS were more adherent to the GFD based on stool and urine GIP results. Patients with NCGS had increased symptom severity at baseline compared with healthy controls. Neither group had significantly increased symptoms after ingestion of gluten.

Background: The significance of a family history of esophageal adenocarcinoma in the progression to esophageal adenocarcinoma in patients with Barrett's esophagus has not been thoroughly evaluated. The purpose of this study is to evaluate the presence of esophageal adenocarcinoma in a first-degree relative in patients with Barrett's esophagus. Methods: A retrospective cohort study was conducted of patients with Barrett's esophagus at a tertiary care center undergoing radiofrequency ablation. Family history, demographics, and pathology and endoscopy reports were assessed in all patients. Findings: Three hundred and one patients with Barrett's esophagus were assessed. Nineteen patients who had a diagnosis of esophageal adenocarcinoma on index endoscopy were excluded. Nineteen (6.7%) patients had a first-degree relative with esophageal adenocarcinoma. Four (21.1%) of these patients progressed to esophageal adenocarcinoma. Of patients without first-degree relative with esophageal adenocarcinoma 22/263 (8.7%) progressed to esophageal adenocarcinoma. In a logistic regression model adjusted for sex and the number of radiofrequency ablation treatments, we found that family history of esophageal adenocarcinoma was a significant independent predictor of progression to esophageal adenocarcinoma (odds ratio = 5.55, 95% confidence interval: 1.47-20.0). Conclusion: Our study indicates that Barrett's esophagus patients with a first-degree family member with esophageal adenocarcinoma are at 5.5-fold higher risk for disease progression to esophageal adenocarcinoma. Family history of esophageal adenocarcinoma in Barrett's esophagus patients should be considered in patient surveillance and radiofrequency ablation treatment, beyond recommended guidelines.

Sporadic Alzheimer's disease (SAD), an age-associated dementia, is described as neuronal loss and marked cognitive impairment. Ellagic acid (EA) is a phenolic phytoconstituent obtained from grains and fruits, having evident antioxidant effects and known to modulate several endogenous molecular signals in humans in a beneficial way. The current study evaluated the safety profile of EA in the SH-SY5Y human neuroblastoma cell line, performing anti-oxidative effect by DPPH assay, and evaluating anti-AchE (acetylcholinesterase) effect against AchE enzyme from Electrophorus electricus. The observations were further confirmed by in vivo therapeutic effects in streptozotocin (STZ)-induced SAD rats in the context of altered biochemical and behavioral features. Treatment with EA (50â¯mg/kg, p.o.) for 30â¯days revealed reduction in STZ (3â¯mg/kg i.c.v.) prompted SAD and associated biochemical abnormalities in experimental rats which included diminished oxidative stress profile, pro-inflammatory markers i.e. GFAP and CRP; AchE level, and amyloid-ß plaque level. Moreover, an elevated level of synaptophysin indicated improved synaptic connectivity, and intact neural architecture showed neuroprotection in the EA group. Furthermore, the behavioral investigation by maze paradigms revealed reduced locomotor behavior, irregular spontaneous alternation, declination in memory score and increased memory errors in SAD rats. EA treatment normalized these SAD-associated abnormal behavioral representations in rats. Hence our findings suggest neuroprotective effects of EA and improvement in cognitive behavior in SAD rats.

OPINION STATEMENT: Pancreatic fluid collections are a frequent complication of acute pancreatitis. The revised Atlanta criterion classifies chronic fluid collections into pseudocysts and walled-off pancreatic necrosis (WON). Symptomatic PFCs require drainage options that include surgical, percutaneous, or endoscopic approaches. With the advent of newer and more advanced endoscopic tools and expertise, minimally invasive endoscopic drainage has now become the preferred approach. An endoscopic ultrasonography (EUS)-guided approach for pancreatic fluid collection drainage is now the preferred endoscopic approach. Both plastic stents and metal stents are efficacious and safe; however, metal stents may offer an advantage, especially in infected pseudocysts and in WON. Direct endoscopic necrosectomy is often required in WON. Lumen apposing metal stents allow for direct endoscopic necrosectomy and debridement through the stent lumen and are now preferred in these patients. Endoscopic retrograde cholangiopancreatography with pancreatic duct exploration should be performed concurrent to PFC drainage in patients with suspected PD disruption. PD disruption is associated with an increased severity of pancreatitis, an increased risk of recurrent attacks of pancreatitis and long-term complications, and a decreased rate of PFC resolution after drainage. Ideally, pancreatic ductal disruption should be bridged with endoscopic stenting.
RESUMEN
BACKGROUND AND OBJECTIVES: Data on the risk of acute pancreatitis following endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreatic cystic lesions are limited. The aim of our study was to evaluate the frequency of acute pancreatitis after EUS-FNA of pancreatic cysts and solid lesions, and determine whether there was a difference in pancreatitis risk in patients with side branch intraductal papillary mucinous neoplasms (SB-IPMN). PATIENTS AND METHODS: A retrospective review of patients who underwent EUS-FNA of pancreatic cysts and solid lesions was performed. The primary outcome measure was development of acute pancreatitis after EUS-FNA. Factors associated with acute pancreatitis were examined by statistical analysis to determine independent predictors of acute pancreatitis. Statistical significance was determined at a P ≤ 0.05. RESULTS: We identified 186 patients with pancreatic cystic lesions and 557 with solid lesions in which EUS-FNA was performed. The median size of the cysts was 19 mm (range: 10-66 mm). There were 37 IPMNs, 33 mucinous cystic neoplasms, 58 serous cysts and 46 pseudocysts and 12 solid-cystic ductal carcinomas. The majority of patients (75%) with solid lesions were diagnosed with adenocarcinoma. Patients with pancreatic cysts had a statistically greater frequency of developing pancreatitis after EUS-FNA when compared to those with solid lesions (2.6% vs. 0.36% respectively; P = 0.13). In patients with cysts, there were no statistically significant differences between the two groups (with and without pancreatitis) with regard to a cyst location, size of the cyst, and number of needle passes or trainee involvement. Patients with SB-IPMN had a statistically higher frequency of pancreatitis after EUS-FNA compared to those with other cyst types (8% vs. 1.3% respectively; odds ratio = 6.4, 95% confidence intervals = 1.0-40.3, P = 0.05). DISCUSSION: Patients with SB-IPMN are at a higher risk of developing acute pancreatitis after a EUS-FNA. Alternative means of diagnosis such as magnetic resonance cholangiopancreatogram might be necessary to avoid risk of EUS-FNA.

Pancreatic tumors with osteoclast-like giant cells are rare, with only 50 cases published to date. We report a case of a 67-year-old male with a new diagnosis of follicular non-Hodgkin's lymphoma with an incidental pancreatic body mass on abdominal imaging. Cytology from the pancreatic mass obtained via endoscopic ultrasound-directed fine-needle aspiration (EUS-FNA) revealed an undifferentiated carcinoma with osteoclast-like giant cells.
RESUMEN
Intramural hematomas have rarely been associated with pancreatitis, and to date there is only 1 case report of an intramural hematoma occurring with pancreatic adenocarcinoma. We describe a patient who presented with gastric outlet obstruction secondary to a spontaneous intramural duodenal hematoma and was found to have a pancreatic adenocarcinoma on endoscopic ultrasound (EUS) after it was not visualized by computed tomography (CT).
