Reduction in vitro of the minor Fusarium mycotoxin beauvericin employing different strains of probiotic bacteria
2012
Abstract The interaction between the minor Fusarium mycotoxins BEA and 13 bacterial strains characteristic of the gastrointestinal tract as Bifidobacterium longum , Bifidobacterium bifidum , Bifidobacterium breve , Bifidobacterium adolescentes , Lactobacillus rhamnosus , Lactobacillus casei-casei , Lactobacillus plantarum , Eubacterium crispatus , Salmonella fecalis , Salmonella termofilus , Lactobacillus ruminis , Lactobacillus casei and Lactobacillus animalis was studied. The fermentations were carried out in the liquid medium of MRS during 4, 12, 16, 24 and 48 h at 37 °C, under anaerobic conditions. Levels of BEA in the fermentation liquid, on the cell walls and on the internal part of t…
Unique Microbial Catabolic Pathway for the Human Core N-Glycan Constituent Fucosyl-α-1,6-N-Acetylglucosamine-Asparagine
2020
The survival of commensal bacteria in the human gut partially depends on their ability to metabolize host-derived molecules. The use of the glycosidic moiety of N-glycoproteins by bacteria has been reported, but the role of N-glycopeptides or glycoamino acids as the substrates for bacterial growth has not been evaluated. We have identified in Lactobacillus casei strain BL23 a gene cluster (alf-2) involved in the catabolism of the glycoamino acid fucosyl-α-1,6-N-GlcNAc-Asn (6′FN-Asn), a constituent of the core-fucosylated structures of mammalian N-glycoproteins. The cluster consists of the genes alfHC, encoding a major facilitator superfamily (MFS) permease and the α-l-fucosidase AlfC, and t…
Production of functional probiotic, prebiotic, and synbiotic ice creams
2010
In this work, 3 types of ice cream were produced: a probiotic ice cream produced by adding potentially probiotic microorganisms such as Lactobacillus casei and Lactobacillus rhamnosus; a prebiotic ice cream produced by adding inulin, a prebiotic substrate; and a synbiotic ice cream produced by adding probiotic microorganisms and inulin in combination. In addition to microbial counts, pH, acidity, and physical and functional properties of the ice creams were evaluated. The experimental ice creams preserved the probiotic bacteria and had counts of viable lactic acid bacteria, after frozen storage that met the minimum required to achieve probiotic effects. Moreover; most of the ice creams show…
Lactose Intolerance and Self-Reported Milk Intolerance: Relationship with Lactose Maldigestion and Nutrient Intake
1998
Background: The relationship between lactose-maldigestion, self-reported milk intolerance and gastrointestinal symptoms has not been clearly defined.Objectives: To evaluate: a) the prevalence of lactose maldigestion and lactose intolerance in a sample of the general population taken from a rural center; b) the frequency of self-reported milk-intolerance and its correlation with lactose-maldigestion; c) the influence of lactose maldigestion, lactose intolerance and self-reported milk intolerance on dietary habits and consumption of total calories, protein, and calcium.Subjects: We studied a randomized sample of the general population in a small center in Sicily. 323 subjects (150 males, 173 …
Endomicroscopy of Small Bowel Diseases: Coeliac Disease, Lymphoma
2007
The different components making up the complement of immune elements within the alimentary tract vary greatly. In contrast to the Waldeyer’s ring region, the oesophagus and stomach are normally almost devoid of such immune apparatus, presumably because of the rapid transit of food and the chemically hostile environment for micro-organisms provided by salivary and gastric secretions. Only in pathological conditions, such as viral or fungal oesophageal infections, reflux oesophagitis or Helicobacter gastritis, does one encounter acquired mucosa-associated lymphoid tissue in these sites [1]. By contrast, the large and small bowel normally possess mucosa-associated lymphoid tissue (MALT), most …
Prognostic implications of surgical specimen quality on the oncological outcomes of open and laparoscopic surgery in mid and low rectal cancer
2021
Abstract Purpose Determine differences in pathologic outcomes between laparoscopic (LAP) and open surgery (OPEN) for mid and low rectal cancer and its influence in long-term oncological outcomes. Methods Retrospective case matched study at a tertiary institution. Adults with rectal cancer below 12 cm from the anal verge operated between January 2005 and September 2018 were included. Primary outcomes were quality of specimen, overall survival (OS), disease-free survival (DFS), and local recurrence (LR). Results The study included 311 patients, LAP = 108 (34.7%), OPEN = 203 (65,3%). A successful resection was accomplished in 81% of the LAP group and in 84.5% of the OPEN (p = 0.505). No differ…
Association of mechanical bowel preparation with oral antibiotics and anastomotic leak following left sided colorectal resection: an international, m…
2018
INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 Left Sided Colorectal Resection audit was performed. Patients undergoing elective left sided colonic or rectal resection with primary anastomosis between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary out…
Small bowel gastrointestinal stromal tumor presenting with gastrointestinal bleeding in patient with type 1 Neurofibromatosis: Management and laparos…
2021
Highlights • A multidisciplinary team is mandatory for the correct management of hemorrhagic GIST and its complications. • There is a well-known association between type 1 Neurofibromatosis and GIST. • Type 1 Neurofibromatosis-GIST and sporadic GIST have different behaviour. • In case of localised and resectable GIST surgical treatment is the mainstay. • Laparoscopic approach, if performed correctly, is safe and effective with better short-term outcomes then open surgery.
The colovescical fistula in diverticular disease: Laparoscopic approach in two different cases
2020
Highlights • The colovescical fistula is one of the complications of diverticular disease. • It can cause typical symptoms like pneumaturia and fecaluria affecting the quality of life and sometimes leading to death, usually secondary to sepsis. • We studied two patients with clinical, radiological and endoscopic diagnosis of colovescical fistula as a consequence of diverticular disease. • We performed a totally laparoscopic treatment with colonic resection and closure of the fistula with intracorporeal sutures. • The presence of a colovescical fistula significantly increases the difficult of the laparoscopic colonic resection.
Combined endo-laparoscopic treatment of large gastrointestinal stromal tumor of the stomach: Report of a case and literature review
2020
Highlights • We report a case of 75-year-old Caucasian men with unknown voluminous gastric GIST, who came to our attention complaining melena. We decided to perform a laparoscopic-endoscopic combined surgical approach. • Intraoperative endoscopy identified gastric GIST and confirmed the submucosal origin and the integrity of the capsule. A 10 cm laparoscopic gastrotomy was carried out along the gastric found in order to realize a laparo-endoscopic rendez-vous technique. • Laparoscopy has rapidly become a preferable approach for gastric GISTs surgical treatment. The magnified view and the lesser invasiveness of laparoscopic technique allow the surgeon to perform a more meticulous dissection,…
