Metabolomics reveals a differential attitude in phytochemical profile of black tea ( Var. ) during processing.

Black tea's quality and flavor are largely influenced by its processing stages, which affect its volatile and non-volatile phytochemicals. This study aimed to optimized black tea manufacturing by investigating withering time, fermentation time, and temperature's impact on sensory quality. Using a U* (15) uniform design, optimal conditions were determined: 14 h of withering, 5.

Recent Approaches to the Formulation, Uses, and Impact of Edible Coatings on Fresh Peach Fruit.

Peaches are among the most well-known fruits in the world due to their appealing taste and high nutritional value. Peach fruit, on the other hand, has a variety of postharvest quality issues like chilling injury symptoms, internal breakdown, weight loss, decay, shriveling, and over-ripeness, which makes a challenging environment for industries and researchers to develop sophisticated strategies for fruit quality preservation and extending shelf life. All over the world, consumers prefer excellent-quality, high-nutritional-value, and long-lasting fresh fruits that are free of chemicals.

Tea Harvesting and Processing Techniques and Its Effect on Phytochemical Profile and Final Quality of Black Tea: A Review.

Tea () has grown for over 300 years and is recognized worldwide as among other well-renowned crops. The quality of black tea depends on plucking (method, standard, season, and intervals), withering and rolling (time and temperature), fermentation (time, temperature, and RH), drying (temperature and method), and storage conditions, which have a high influence on the final quality of black tea. At the rolling stage, the oxidation process is initiated and ends at the early drying stage until the enzymes that transform tea polyphenols into thearubigins (TRs) and theaflavins (TFs) are denatured by heat.

A machine learning-based choledocholithiasis prediction tool to improve ERCP decision making: a proof-of-concept study.

Background: Previous studies demonstrated limited accuracy of existing guidelines for predicting choledocholithiasis, leading to overutilization of endoscopic retrograde cholangiopancreatography (ERCP). More accurate stratification may improve patient selection for ERCP and allow use of lower-risk modalities.

Methods: A machine learning model was developed using patient information from two published cohort studies that evaluated performance of guidelines in predicting choledocholithiasis.

Lactated Ringers Use in the First 24 Hours of Hospitalization Is Associated With Improved Outcomes in 999 Patients With Acute Pancreatitis.

Introduction: Recent pilot trials in acute pancreatitis (AP) found that lactated ringers (LR) usage may result in decreased risk of moderately severe/severe AP compared with normal saline, but their small sample sizes limit statistical power. We investigated whether LR usage is associated with improved outcomes in AP in an international multicenter prospective study.

Methods: Patients directly admitted with the diagnosis of AP were prospectively enrolled at 22 international sites between 2015 and 2018.

Incidence, severity, and mortality of post-ERCP pancreatitis: an updated systematic review and meta-analysis of 145 randomized controlled trials.

Background And Aims: The incidence, severity, and mortality of post-ERCP pancreatitis (PEP) largely remain unknown with changing trends in ERCP use, indication, and techniques. We sought to determine the incidence, severity, and mortality of PEP in consecutive and high-risk patients based on a systemic review and meta-analysis of patients in placebo and no-stent arms of randomized control trials (RCTs).

Methods: The MEDLINE, Embase, and Cochrane databases were searched from the inception of each database to June 2022 to identify full-text RCTs evaluating PEP prophylaxes.

Effective, safe and efficient porcine model of Forrest Ib bleeding gastric and colonic ulcers.

Background: Developing effective gastrointestinal (GI) bleeding animal models is necessary to advance endoscopic hemostasis methods and train endoscopists on their use. Our aim, therefore, was to develop an effective and safe porcine GI bleeding model in the stomach and colon of large and small-sized oozing-type ulcers.

Methods: Gastric and colonic bleeding ulcers were created using either a hybrid endoscopic submucosal dissection (ESD) technique or a cap-assisted endoscopic mucosal resection (EMR-C) technique in 14 pigs.

Non-steroidal anti-inflammatory drugs, intravenous fluids, pancreatic stents, or their combinations for the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis: a systematic review and network meta-analysis.

Background: Non-steroidal anti-inflammatory drugs (NSAIDs), intravenous fluid, pancreatic stents, or combinations of these have been evaluated in randomised controlled trials (RCTs) for the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, but the comparative efficacy of these treatments remains unclear. Our aim was to do an exploratory network meta-analysis of previous RCTs to systematically compare the direct and indirect evidence and rank NSAIDs, intravenous fluids, pancreatic stents, or combinations of these to determine the most efficacious method of prophylaxis for post-ERCP pancreatitis.

Methods: We searched PubMed, Embase, and the Cochrane Central Register from inception to Nov 15, 2020, for full-text RCTs that evaluated the efficacy of NSAIDs, pancreatic stents, intravenous fluids, or combinations of these for post-ERCP pancreatitis prevention in adult (aged ≥18 years) patients undergoing ERCP.

Erratum: Comparative diagnostic accuracy of EUS needles in solid pancreatic masses: a network meta-analysis.

[This corrects the article DOI: 10.1055/a-1381-7301.].

Comparative diagnostic accuracy of EUS needles in solid pancreatic masses: a network meta-analysis.

Endoscopic ultrasound (EUS)-guided tissue sampling is the standard of care for diagnosing solid pancreatic lesions. While many two-way comparisons between needle types have been made in randomized controlled trials (RCTs), it is unclear which size and type of needle offers the best probability of diagnosis. We therefore performed a network meta-analysis (NMA) to compare different sized and shaped needles to rank the diagnostic performance of each needle.

Morphologic Severity of Acute Pancreatitis on Imaging Is Independently Associated with Opioid Dose Requirements in Hospitalized Patients.

Background: Prior studies have evaluated clinical characteristics associated with opioid dose requirements in hospitalized patients with acute pancreatitis (AP) but did not incorporate morphologic findings on CT imaging.

Aims: We sought to determine whether morphologic severity on imaging is independently associated with opioid dose requirements in AP.

Methods: Adult inpatients with a diagnosis of AP from 2006 to 2017 were reviewed.

Dynamic changes in the pancreatitis activity scoring system during hospital course in a multicenter, prospective cohort.

Background And Aim: The primary aim was to validate the Pancreatitis Activity Scoring System (PASS) in a multicenter prospectively ascertained acute pancreatitis (AP) cohort. Second, we investigated the association of early PASS trajectories with disease severity and length of hospital stay (LOS).

Methods: Data were prospectively collected through the APPRENTICE consortium (2015-2018).

Post-Acute Pancreatitis Pancreatic Exocrine Insufficiency: Rationale and Methodology of a Prospective, Observational, Multicenter Cohort Study.

Objectives: We describe the methodology of Post-Acute Pancreatitis Pancreatic Exocrine Insufficiency (PAPPEI), a prospective, observational, multicenter cohort study. The objectives of PAPPEI are to estimate the incidence rate of post-acute pancreatitis (AP) pancreatic exocrine insufficiency (PEI), define factors that determine the development of post-AP PEI, and evaluate the impact of post-AP PEI on nutritional status and quality of life.

Methods: Enrollment started in June 2017 in 3 expert academic centers in the United States.

Risk factors for lymph node metastasis and survival of patients with nonampullary duodenal carcinoid tumors treated with endoscopic therapy versus surgical resection: analysis of the Surveillance, Epidemiology, and End Results program.

Background And Aims: Endoscopic therapy (ET) has been used to treat nonampullary duodenal neuroendocrine tumors (NAD-NETs) ≤10 mm in size, but data on long-term outcomes are limited. In addition, management of 11- to 19-mm NAD-NETs is not well defined because of variable estimates of risk of metastasis. We aimed to determine the prevalence and risk factors of metastasis of NAD-NETs ≤19 mm and evaluate the long-term survival of patients after ET as compared with radical surgery.

Digestive Manifestations in Patients Hospitalized With Coronavirus Disease 2019.

Background & Aims: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19.

Methods: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America.

Fluid type and volume reduce risk of post-ERCP pancreatitis and length of hospital stay in high-risk patients: a secondary analysis of the INDIEH trial.

Impact of intravenous fluid administration on prophylaxis against post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) has not been rigorously evaluated among patients at high-risk for PEP. Effect of volume and type of fluid administered on PEP incidence was studied through a secondary analysis of high-risk patients who underwent endoscopic retrograde cholangopancreatography (ERCP) as a part of a randomized controlled trial in which all patients received rectal indomethacin. Periprocedural fluid was defined as fluid infused during and after ERCP.

Comparable Cancer-Specific Mortality of Patients With Early Gastric Cancer Treated With Endoscopic Therapy vs Surgical Resection.

Background & Aims: Endoscopic therapy is used commonly for superficial gastric cancer with very low risk of metastasis to the lymph nodes. However, limited population-based studies from the West have evaluated long-term outcomes of patients who received endoscopic therapy vs surgery.

Methods: We used the Surveillance Epidemiology and End Results database to identify and compare features and outcomes of patients who underwent endoscopic therapy (n = 786) or surgery (n = 2577) for Tis or T1aN0M0 superficial gastric cancer, diagnosed from 1998 to 2014.

Design and validation of a patient-reported outcome measure scale in acute pancreatitis: the PAN-PROMISE study.

Objective: This study aimed to develop and validate a patient-reported outcome measure (PROM) in acute pancreatitis (AP) as an endpoint centred on the patient.

Design: A PROM instrument (PAtieNt-rePoRted OutcoMe scale in acute pancreatItis, an international proSpEctive cohort study, PAN-PROMISE scale) was designed based on the opinion of patients, professionals and an expert panel. The scale was validated in an international multicentre prospective cohort study, describing the severity of AP and quality of life at 15 days after discharge as the main variables for validation.

The State of Mentorship and Pancreatic Research Among Trainees in Pancreatology: A Multinational Survey Study.

Objectives: The recent decrease seen in pancreatic research and young investigator involvement may reflect inadequate mentorship. This study aimed to describe the current state of mentorship in pancreatic research and evaluate how mentorship is associated with research productivity.

Methods: In this prospective study, a survey addressing mentorship and research was distributed to trainees worldwide.

Cystic fibrosis transmembrane conductance regulator modulators reduce the risk of recurrent acute pancreatitis among adult patients with pancreas sufficient cystic fibrosis.

Background: Approximately 1 in 5 patients with pancreas sufficient cystic fibrosis (PS-CF) will develop acute pancreatitis (AP). It is not known whether ivacaftor alone or in combination with other CFTR (cystic transmembrane regulator) modulators (tezacaftor or lumacaftor) can reduce the risk of AP in patients with PS-CF and AP history.

Methods: We retrospectively queried the CF registry at our institution for adult patients with PS-CF, a documented history of AP and initiation of CFTR modulators for pulmonary indications.

Angiotensin II receptor blockers and gastrointestinal adverse events of resembling sprue-like enteropathy: a systematic review.

Background: Olmesartan, an angiotensin II receptor blocker (ARB), is associated with gastrointestinal symptoms resembling sprue-like enteropathy. Some have proposed that enteropathy may be a class effect rather than olmesartan-specific. We performed a systematic review to identify literature of sprue-like enteropathy for all ARBs.
