The aim of the current report is to evaluate the effects of a combination of lactoferrin, lysozyme, lactobacillus, resveratrol, vitamins, and oligoelements (PIRV-F20) on the exercise capacity of post-COVID-19 patients. : A retrospective analysis of consecutive patients referred to a specific outpatient clinic dedicated to post-COVID-19 condition from April 2022 to April 2023 was conducted.

Beyond the gut: Investigating the mechanism of formation of β-casomorphins in human blood.

To evaluate the potential differences in the propensity of β-casein A1 (β-CNA1) and A2 (β-CNA2) from bovine milk to release health-relevant β-casomorphins (BCMs), food-derived peptides were monitored over time in the blood of eight human volunteers who consumed milk containing both protein variants. Liquid chromatography coupled with high resolution tandem mass spectrometry revealed interindividual variability of milk peptidomic profiles in human blood. BCMs were not detected, whereas BCM precursors originating from both β-CNA1 and β-CNA2 were ascertained, with β-CNA2-derived peptides showing a slightly greater susceptibility to proteolysis.

Upcoming Italian clinical practice guidelines on endoscopic bariatric treatment of overweight and obesity: design and methodological aspects.

Obesity/overweight and its complications are a growing problem in many countries. Italian Society of Bariatric and Metabolic Surgery for Obesity (Società Italiana di Chirurgia dell'Obesità e delle Malattie Metaboliche-SICOB) decided to develop the first Italian guidelines for the endoscopic bariatric treatment of obesity. The creation of SICOB Guidelines is based on an extended work made by a panel of 44 members and a coordinator.

Site and duration of abdominal pain discriminate symptomatic uncomplicated diverticular disease from previous diverticulitis patients.

Abdominal pain in patients with diverticular disease (DD) can be challenging in clinical practice. Patients with symptomatic uncomplicated diverticular disease (SUDD) and patients with a previous acute diverticulitis (PD) may share a similar clinical pattern, difficult to differentiate from irritable bowel syndrome (IBS). We used standardized questionnaires for DD (short and long lasting abdominal pain) and IBS (following Rome III Criteria) to assess clinical features of abdominal pain, in terms of presence, severity and length, in SUDD and PD patients.

Prevalence of Rome IV Pediatric Diagnostic Questionnaire-Assessed Disorder of Gut-Brain Interaction, Psychopathological Comorbidities and Consumption of Ultra-Processed Food in Pediatric Anorexia Nervosa.

Anorexia nervosa (AN) is a severe eating disorder primarily affecting children and adolescents. Disorders of the gut-brain interaction (DGBIs) have gained recognition as significant symptoms in individuals with AN. However, limited studies have explored GI symptoms in pediatric populations with AN using age-specific diagnostic tools.

The 1st EoETALY Consensus on the Diagnosis and Management of Eosinophilic Esophagitis-Current Treatment and Monitoring.

The present document constitutes Part 2 of the EoETALY Consensus Statements guideline on the diagnosis and management of eosinophilic esophagitis (EoE) developed by experts in the field of EoE across Italy (i.e., EoETALY Consensus Group).

Intranasal administration of Escherichia coli Nissle expressing the spike protein of SARS-CoV-2 induces long-term immunization and prevents spike protein-mediated lung injury in mice.

While current anti-Spike protein (SP) vaccines have been pivotal in managing the pandemic, their limitations in delivery, storage, and the inability to provide mucosal immunization (preventing infections) highlight the ongoing necessity for research and innovation. To tackle these constraints, our research group developed a bacterial-based vaccine using a non-pathogenic E. coli Nissle 1917 (EcN) strain genetically modified to express the SARS-CoV-2 spike protein on its surface (EcN-pAIDA1-SP).

Intrarectal Administration of Adelmidrol plus Hyaluronic Acid Gel Ameliorates Experimental Colitis in Mice and Inhibits Pro-Inflammatory Response in Ex Vivo Cultured Biopsies Derived from Ulcerative Colitis-Affected Patients.

Improving clinical outcomes and delaying disease recrudescence in Ulcerative Colitis (UC) patients is crucial for clinicians. In addition to traditional and new pharmacological therapies that utilize biological drugs, the development of medical devices that can ameliorate UC and facilitate the remission phase should not be overlooked. Drug-based therapy requires time to be personalized and to evaluate the benefit/risk ratio.

Modern Achalasia: Diagnosis, Classification, and Treatment.

Achalasia is a major esophageal motor disorder featured by the altered relaxation of the esophagogastric junction in the absence of effective peristaltic activity. As a consequence of the esophageal outflow obstruction, achalasia patients present with clinical symptoms of dysphagia, chest pain, weight loss, and regurgitation of indigested food. Other less specific symptoms can also present including heartburn, chronic cough, and aspiration pneumonia.

Laparoscopic Heller-Dor myotomy in elderly achalasia patients: a single center experience with PSM analysis.

Introduction: Achalasia is a rare esophageal motility disorder of unknown etiology. With the ageing of the general population, treatment in elderly patients has become increasingly common; however, the gold standard treatment in this population remains unclear. The aim of this study was to evaluate the outcomes of laparoscopic Heller-Dor myotomy (LHM) in geriatric patients.

Preservation of the inferior mesenteric artery VS ligation of the inferior mesenteric artery in left colectomy: evaluation of functional outcomes-a prospective non-randomized controlled trial.

Vascular approach during elective laparoscopic left colectomy impacts post-operative outcomes. The aim of our study was to evaluate how different approaches impact positively defecatory, urinary and sexual functions and quality of life during elective laparoscopic left colectomy. A prospective non-randomized controlled trial at two tertiary center was conducted.

Patients with Diverticular Disease Have Different Dietary Habits Compared to Control Subjects: Results from an Observational Italian Study.

The role of dietary habits as risk factor for the development of diverticular complications has strongly emerged in the last years. We aimed to evaluate possible differences in dietary habits between patients with diverticular disease (DD) and matched controls without diverticula. Dietary habits were obtained from standardized food frequency questionnaires collected at entry to the Diverticular Disease Registry (REMAD).

A Multidisciplinary Approach for Type 2 Allergic Diseases: What Do Biologics Teach Us?

Patients with atopic/allergic disorders, including atopic dermatitis (AD), allergic rhino-conjunctivitis (AR), chronic rhinosinusitis with/without nasal polyps (CRSwNP/CRSsNP), bronchial asthma, food allergy, and eosinophilic esophagitis (EoE), often share a common genetic background, a type Th2 polarized immune response, and several environmental factors [...

Oral Immunization with Expressing SARS-CoV-2 Spike Protein Induces Mucosal and Systemic Antibody Responses in Mice.

As of October 2022, the COVID-19 pandemic continues to pose a major public health conundrum, with increased rates of symptomatic infections in vaccinated individuals. An ideal vaccine candidate for the prevention of outbreaks should be rapidly scalable, easy to administer, and able to elicit a potent mucosal immunity. Towards this aim, we proposed an engineered () (EcN) strain with SARS-CoV-2 spike protein (SP)-coding plasmid, which was able to expose SP on its cellular surface by a hybridization with the adhesin involved in diffuse adherence 1 (AIDA1).

Robotic Surgery and Functional Esophageal Disorders: A Systematic Review and Meta-Analysis.

The functional disease of the esophago-gastric junction (EGJ) is one of the most common health problems. It often happens that patients suffering from GERD need surgical management. The laparoscopic fundoplication has been considered the gold standard surgical treatment for functional diseases of the EGJ.

Italian guidelines for the management of irritable bowel syndrome: Joint Consensus from the Italian Societies of: Gastroenterology and Endoscopy (SIGE), Neurogastroenterology and Motility (SINGEM), Hospital Gastroenterologists and Endoscopists (AIGO), Digestive Endoscopy (SIED), General Medicine (SIMG), Gastroenterology, Hepatology and Pediatric Nutrition (SIGENP) and Pediatrics (SIP).

The irritable bowel syndrome (IBS) is a chronic disorder of gut-brain interaction. IBS is still associated with areas of uncertainties, especially regarding the optimal diagnostic work-up and the more appropriate management. Experts from 7 Italian Societies conducted a Delphi consensus with literature summary and voting process on 27 statements.

Targeting the endocannabinoid system for the treatment of abdominal pain in irritable bowel syndrome.

The management of visceral pain in patients with disorders of gut-brain interaction, notably irritable bowel syndrome, presents a considerable clinical challenge, with few available treatment options. Patients are increasingly using cannabis and cannabinoids to control abdominal pain. Cannabis acts on receptors of the endocannabinoid system, an endogenous system of lipid mediators that regulates gastrointestinal function and pain processing pathways in health and disease.

N-Palmitoyl-D-Glucosamine Inhibits TLR-4/NLRP3 and Improves DNBS-Induced Colon Inflammation through a PPAR-α-Dependent Mechanism.

Similar to canine inflammatory enteropathy, inflammatory bowel disease (IBD) is a chronic idiopathic condition characterized by remission periods and recurrent flares in which diarrhea, visceral pain, rectal bleeding/bloody stools, and weight loss are the main clinical symptoms. Intestinal barrier function alterations often persist in the remission phase of the disease without ongoing inflammatory processes. However, current therapies include mainly anti-inflammatory compounds that fail to promote functional symptoms-free disease remission, urging new drug discoveries to handle patients during this step of the disease.

Sleeve Gastrectomy-Induced Body Mass Index Reduction Increases the Intensity of Taste Perception's and Reduces Bitter-Induced Pleasantness in Severe Obesity.

: The sense of taste is involved in food behavior and may drive food choices, likely contributing to obesity. Differences in taste preferences have been reported in normal-weight as compared to obese subjects. Changes in taste perception with an increased sweet-induced sensitivity have been reported in surgically treated obese patients, but data regarding the perception of basic tastes yielded conflicting results.
