Abstract: Acute diverticulitis of the colon represents a significant burden for national health systems, in terms of direct and indirect costs. Although current guidelines recommend use of antibiotics for the outpatient treatment of acute uncomplicated diverticulitis, evidence for this is still lacking. Hence, significant effort is now being made to identify the appropriate therapeutic approach to treat and prevent relapses of diverticulitis. Outpatient treatment has been identified as a safe and effective therapeutic...

Abstract: Introduction: Diverticular disease (DD) of the colon is a widespread disease, which shows worldwide increasing incidence and represents a significant burden for National Health Systems. The current guidelines claim that symptomatic uncomplicated DD (SUDD) has to be treated with spasmolithics and high-fiber diet, whereas both uncomplicated and complicated acute diverticulitis has to be treated with antibiotics. However, new physiopathological knowledge suggests that further treatment may be promising. Areas covered:...

Abstract: INTRODUCTION: Necrotic tissue infection can worsen the prognosis of severe acute pancreatitis (SAP), and probiotics have been shown to be beneficial in reducing the infection rate in animal experiments and primary clinical trials. However, the results of multicenter randomized clinical trials have been contradictory. The aim of this study was to systematically review and quantitatively analyze all randomized controlled trials with regard to important outcomes in patients with predicted SAP who received probiotics.METHODS:...

Abstract: Gut microbiota plays a significant role in human health and energy balance, and provides protection against disease states. An altered balance between microbiota and its host (dysbiosis) would appear to contribute to the development of Inflammatory Bowel Disease (IBD), Crohn's Disease (CD) and Ulcerative Colitis (UC). CD and UC are chronic inflammatory diseases of the gastrointestinal tract that occur in genetically susceptible individuals. Several genes of susceptibility are involved in inappropriate activation...

Abstract: During the last years, the application of probiotics in gynaecological clinical practice has gained increasing relevance regarding therapy and prevention. This trend has also provoked the need for having tailored pharmaceutical preparations containing powerful microbial strains with defined properties. For the development of such preparations, several factors and criteria have to be considered, thereby not only focusing on identity and safety aspects as well as individual properties of the bacterial strains,...

Abstract: Radiant skin and hair are universal indicators of good health. It was recently shown that feeding of probiotic bacteria to aged mice rapidly induced youthful vitality characterised by thick lustrous skin and hair, and enhanced reproductive fitness, not seen in untreated controls. Probiotic-treated animals displayed integrated immune and hypothalamic-pituitary outputs that were isolated mechanistically to microbe-induced anti-inflammatory interleukin-10 and neuropeptide hormone oxytocin. In this way, probiotic...

Abstract: Estrogen deficiency is a major risk factor for osteoporosis that is associated with bone inflammation and resorption. Half of women over the age of 50 will experience an osteoporosis related fracture in their lifetime, thus novel therapies are needed to combat post-menopausal bone loss. Recent studies suggest an important role for gut-bone signaling pathways and the microbiota in regulating bone health. Given that the bacterium Lactobacillus reuteri ATCC PTA 6475 (L. reuteri) secretes beneficial immunomodulatory...

Abstract: The human gut microbiota comprises approximately 100 trillion microbial cells and has a significant effect on many aspects of human physiology including metabolism, nutrient absorption and immune function. Disruption of this population has been implicated in many conditions and diseases, including examples such as obesity, inflammatory bowel disease and colorectal cancer that are highlighted in this review. A logical extension of these observations suggests that the manipulation of the gut microbiota can be...

Abstract: Gut microbiota is known to have a relevant role in our health, and is also related to both gastrointestinal and extradigestive diseases. Therefore, restoring the alteration of gut microbiota represents an outstanding clinical target for the treatment of gut microbiota-related diseases. The modulation of gut microbiota is perhaps an ancestral, innate concept for human beings. At this time, the restoration of gut microbiota impairment is a well-established concept in mainstream medicine, and several therapeutic...

Abstract: The innate lymphoid cells (ILCs) have been grouped into three main categories: ILC1s [T helper (h)1-like cells], ILC2s (Th2-like cells) and ILC3s (Th17-like cells), respectively. In particular, ILC3s are responsible for the secretion of both interleukin (IL)-17 and IL-22, which play either protective (antimicrobial and repairing activities) or harmful (inflammation and tumor growth) roles into the host. Here, some putative interventional studies will be hypothesized, taking into account that activation of innate...

Abstract: Due to their porous structure, aqueous environment and dietary fiber nature arabinoxylan (AX) gels could have potential applications for colon-specific therapeutic molecule delivery. In addition, prebiotic and health related effects of AX have been previously demonstrated. It has been also reported that cross-linked AX can be degraded by bacteria from the intestinal microbiota. However, AX gels have not been abundantly studied as carrier systems and there is no information available concerning their capability...

Abstract: Experts reviewed the literature to determine if partial whey hydrolysed formulas (HF) offers benefits in the dietary management of frequent gastro-intestinal symptoms and allergy prevention. Compared to standard cow's milk-based formulas, partial whey HF confers a limited protective effect against allergic disease in high-risk infants, particularly atopic dermatitis, but not respiratory allergies. No randomised clinical trials have been published on partial whey HF in infants with colicky symptoms. The group...

Abstract: Maintaining "gut health" is a goal for scientists throughout the world. Therefore, microbiota management models for testing probiotics, prebiotics, and synbiotics have been developed. The SHIME® model was used to study the effect of fructooligosaccharide (FOS) on the fermentation pattern of the colon microbiota. Initially, an inoculum prepared from human feces was introduced into the reactor vessels and stabilized over 2 weeks using a culture medium. This stabilization period was followed by a 2-week control...

Abstract: Objective:Better measures are needed to identify infants at risk for developing necrotizing enterocolitis (NEC) and facilitate communication about risk across transitions. Although NEC is multi-factorial, quantification of composite risk for NEC in an individual infant is not clearly defined. The objective of this study was to describe the derivation, validation and calibration testing of a novel clinical NEC risk index, GutCheckNEC. Individual risk factors were weighted to assess composite odds of developing...

Abstract: Gut microbiota influences host health status by providing trophic, protective, and metabolic functions, including bile acid (BA) biotransformation. Microbial imprinting on BA signature modifies pool size and hydrophobicity, thus contributing to BA enterohepatic circulation. Microbiota-targeted therapies are now emerging as effective strategies for preventing and/or treating gut-related diseases. Here, we show that gut microbiota modulation induced by VSL#3 probiotics enhances BA deconjugation and fecal excretion...
