INTRODUCTION: Systemic Sclerosis is known to involve the gastrointestinal system and can lead to multitude of problems predominantly affecting the GI motility. METHODS: It was a prospective, observational, single centre study of fifty consecutive patients with SSc who presented to rheumatology clinic. Gut score was assessed using UCLA SCTC GIT 2.0 questionnaire. 35 patients underwent esophago- gastro duodenoscopy(UGIE), 31 underwent esophageal manometry, 37 underwent lactulose breath test to assess orocaecal transit time (OCTT) and glucose breath test for detecting small intestinal bacterial overgrowth (SIBO) and 36 underwent gastric emptying scintigraphy to measure gastric emptying time...

Eggerthella lenta is increasingly found in patients with severe comorbidities. Because oncologic patients are exposed to emerging pathogens, we aimed to describe the factors associated with E. lenta bacteremia in this immunosuppressed population. Oncology patients with blood cultures positive for E. lenta were retrospectively recorded from 2009 to 2015. Socio-demographic and medical/biological data as well as potential risk factors and mortality were recorded and analyzed. Twenty-three patients were included...

Extra-intestinal complications of Salmonella Typhi (S. Typhi) infections usually occur in endemic countries and in patients with underlying risk conditions. A 14-year-old immunocompetent girl was admitted with respiratory distress owing to S. Typhi pneumonia and pleural empyema. She was a native of Ivory Coast but had lived in France for 4 years and had not travelled abroad for several years. There were no gastro-intestinal symptoms and no S. Typhi carriage was detected in her family. She recovered completely with ceftriaxone and ciprofloxacin and pleural drainage was not required...

Potentially inappropriate prescribing is a common problem, especially in elderly care. To tackle this problem, Irish medical experts have developed a list of criteria when medication should be added or omitted based upon the patient's physical condition and medication use, known as the STOPP and START criteria. The STOPP and START criteria have been formulated to identify the prescribing of potentially inappropriate medicines (PIMs) and potential prescribing omissions (PPOs). One of the most common problems of inappropriate prescribing is gastro-intestinal track bleedings...

We report two cases of bacteremia due to Clostridium difficile from two French hospitals. The first patient with previously diagnosed rectal carcinoma underwent courses of chemotherapy, and antimicrobial treatment, and survived the C. difficile bacteremia. The second patient with colon perforation and newly diagnosed lung cancer underwent antimicrobial treatment in an ICU but died shortly after the episode of C. difficile bacteremia. A review of the literature allowed the identification of 137 cases of bacteremia between July 1962 and November 2016...

Dimethyl fumarate has been demonstrated useful in relapsing remitting multiple sclerosis treatment (Tecfidera®). Nevertheless, since Tecfidera® capsules induce flushing, gastro-intestinal events and other more serious drawbacks, in this investigation a nanoparticle based system to be administered by an alternative way is proposed. In particular this study describes the preparation and characterization of dimethyl fumarate-containing solid lipid nanoparticles (SLN). Namely SLN based on tristearin, tristearin SLN treated with polysorbate 80 and cationic SLN constituted of tristearin in mixture with dimethyldioctadecylammonium chloride were investigated...

The aim of this study was to evaluate the bioactivity of flavonoids extracted from sweet-cherry stems which are often used by a traditional system of medicine to treat gastro-intestinal and urinary tract infections but lacking any consistent scientific evidence; moreover the information about the class of phenolics, their content and the potential bioactivity of such material is very scarce. Thus, in this context, we have set a research study in which we evaluated the profile and content of phenolics extracted from sweet-cherry stems through a conventional (70ºC and 20 min) and ultrasound assisted extraction (40 kHz, room temperature and 20 min)...

BACKGROUND: Continuous delivery to the jejunum of levodopa-carbidopa is a promising therapy in patients with advanced Parkinson's disease, as it reduces motor fluctuation. Percutaneous endoscopic gastrostomy and jejunal tube (PEG-J) placement is a suitable option for this. However, studies focused in PEG-J management are lacking. OBJECTIVES: We report our experience regarding this technique, including technical success, adverse events and outcomes, in patients with advanced Parkinson's disease...

There is a need to find/discover novel leads to treat complex and/or multi-factorial-pathogenic disease(s) like Nonsteroidal anti-inflammatory drugs (NSAID)-induced gastroenteropathy or gastrointestinal (GI) toxicity as it has emerged as an important medical and socioeconomic problem. There is no approved therapeutic strategy to prevent NSAID-induced small intestinal toxicity and highly effective gastro-protective drugs such as ranitidine hydrochloride (RAN) exacerbate it. In this purview, the multi target drug discovery approach (MTDD), combination approach and hit to lead strategies based on the foundation of ethnopharmacology and/or reverse pharmacology holds strong potential...

This study aimed at using grape marc for the growth of lactic acid bacteria and bifidobacteria with the perspective of producing a functional ingredient having antioxidant activity. Lactobacillus plantarum 12A and PU1, Lactobacillus paracasei 14A, and Bifidobacterium breve 15A showed the ability to grow on grape marc (GM) based media. The highest bacterial cell density (>9.0 CFU/g) was found in GM added of 1% of glucose (GMG). Compared to un-inoculated and incubated control fermented GMG showed a decrease of carbohydrates and citric acid together with an increase of lactic acid...

Imaging of the mesenteric vasculature is crucial in diagnosing vascular disease of the gastro-intestinal tract such as acute or chronic mesenteric ischemia caused by arterial stenosis, embolism or thrombosis, mesenteric vein thrombosis and mesenteric aneurysm or dissection. The reference standard for imaging of the mesenteric vasculature is digital subtraction angiography. However, modalities as duplex ultrasonography, computed tomography angiography and magnetic resonance angiography are developing rapidly and may provide accurate imaging non-invasively...

The aim of the present study was to examine how factors (pH, temperature, iron chelators, and free radical scavengers) influence on the chemical stabilities of β-carotene encapsulated by Ulva fasciata polysaccharide (UFP)-stabilized emulsions and the bioaccessibility under in vitro oral-gastro-intestinal digestion conditions. The concentration of β-carotene in emulsions under different environments was determined. Changes in droplet properties, particle size and microstructure, throughout the oral-gastric-intestinal model were measured and the rate and extent of lipid digestion were recorded in the simulated small intestine fluid...

OBJECTIVES: Radical cystectomy (RC) and pelvic lymph-node dissection (LND) is standard treatment for non-metastatic muscle-invasive urothelial bladder cancer (MIBC). However, loco-regional recurrence (LRR) is a common early event associated with poor prognosis. We evaluate 3-year LRR-free (LRRFS), metastasis-free (MFS) and overall survivals (OS) after adjuvant radiotherapy (RT) for pathological high-risk MIBC. MATERIAL AND METHODS: We retrospectively reviewed data from patients in 3 institutions...

Three-dimensional and density-based tumor metrics have been suggested to better discriminate tumor response to treatment than unidimensional metrics, particularly for tumors exhibiting non-uniform size changes. In the developed pharmacometric modeling framework based on data from 77 imatinib-treated gastro-intestinal patients, the time-courses of liver metastases' maximum trans-axial diameters, software-calculated actual volumes (Vactual ) and calculated ellipsoidal volumes were characterized by logistic growth models, where imatinib induced a linear dose-dependent size reduction...

REVIEW
N P Aditya, Yadira Gonzalez Espinosa, Ian T Norton
Increased health risk associated with the sedentary life style is forcing the food manufacturers to look for food products with specific or general health benefits e.g. beverages enriched with nutraceuticals like catechin, curcumin rutin. Compounds like polyphenols, flavonoids, vitamins are the good choice of bioactive compounds that can be used to fortify the food products to enhance their functionality. However due to low stability and bioavailability of these bioactives (both hydrophobic and hydrophilic) within the heterogeneous food microstructure and in the Gastro Intestinal Tract (GIT), it becomes extremely difficult to pass on the real health benefits to the consumers...

Background: Tumor ablation is often employed for unresectable colorectal liver metastases. However, no survival benefit has ever been demonstrated in prospective randomized studies. Here, we investigate the long-term benefits of such an aggressive approach. Methods: In this randomized phase II trial, 119 patients with unresectable colorectal liver metastases (n < 10 and no extrahepatic disease) received systemic treatment alone or systemic treatment plus aggressive local treatment by radiofrequency ablation ± resection...

Data from many preclinical studies, including those using cellular models of colorectal, gastric, gastro-oesophageal and gastro-oesophageal junction cancers, indicate that the hepatocyte growth factor (HGF)-hepatocyte growth factor receptor (c-MET) pathway is vital for the growth, survival and invasive potential of gastrointestinal cancers. Following the availability of data from these various studies, and data on c-MET expression as a biomarker that indicates a poor prognosis in patients with gastrointestinal cancer and increased c-MET expression, inhibitors targeting this pathway have entered the clinic in the past decade...
