Filter by:The aim of this study is to determine the effects of an intervention using a commercially available probiotic in a cohort of acute stroke patients. In order to determine this, a double blinded, randomised and placebo-controlled study design was chosen.
The purpose of this study is to determine if the gas-sensing capsule can be used to identify increased numbers and a change of the composition of microbiota or microorganisms in the gut to assess small intestinal dysbiosis
Due to the high incidence, cancer and the concomitant presence of malnutrition are currently a worldwide public health problem. The loss of weight and body tissues is a common condition in cancer patients with lesions of the airways and digestive tract and is related to anorexia and the presence and duration of gastrointestinal symptoms, such as diarrhea. The latter directly interferes with the progression of enteral diets, which are administered in order to provide adequate nutritional support for the recovery of patients and nutritional status. In this sense, the importance of measures to help reduce diarrhea episodes is reinforced, aiming at the adequate infusion of enteral diets and, consequently, nutritional needs. It is known that the use of antimicrobials is closely related to the increased incidence of nasocomial diarrhea, as it facilitates colonization by pathogenic bacteria, such as Clostridium difficile. In addition, nosocomial diarrhea is a very relevant occurrence due to the financial burden it causes for the hospital institution, which can also worsen the patient's clinical condition, since he is weakened due to the underlying disease. Despite these important aspects, studies carried out with the aim of reducing diarrhea episodes in patients with airway and digestive lesions are still not described in the literature. In this context, the use of symbiotics presents itself as a possibly beneficial alternative, considering the role of probiotics and prebiotics in the modulation of intestinal function. In this sense, this work aims to evaluate the impact of perioperative supplementation with symbiotic on clinical outcomes and intestinal function of patients with colon cancer and digestive airways undergoing colorectal resection. It is assumed that the use of symbiotics could have better results than the use of probiotics and isolated prebiotics.
The primary objective of this case-control study aims to explore the role of bacterium Ruminococcus gnavus (R. gnavus) with intestinal biopsy and faecal sampling in the initiation and the development of spondyloarthritis (SPA) in comparison with health control subjets (patients without chronic disease but have indication to digestive endoscopy).
Periodontitis and inflammatory bowel disease have been associated by meta-epidemiologic evidence, although their mechanistic connection needs to be further explored. Oral-gut axis is implicated in the pathogenesis of several chronic inflammatory conditions, but to date no studies have evaluated the impact of periodontal treatment on gut ecology. Thus, the present randomised clinical trial is aimed at investigating the effect of intensive or conventional periodontal therapy on the gut microbiome and parameters of systemic inflammation of patients diagnosed with inflammatory bowel disease.
In order to understand the life history of the breast milk flora, explore its composition, source of strains, and ability to colonize the baby's intestinal environment, to find out strains with the potential of probiotics in breast milk
In the diagnosis and treatment of patients with sepsis, through routine stool testing and dynamic testing of coagulation function, we found that patients often have stools that are not formed, the proportion of main fecal bacteria is imbalanced, the level of blood bacterial toxins rises, and the abnormal coagulation status indicate the gut microbiome dysbiosis may play an important regulatory role in abnormal blood coagulation in patients with sepsis. Therefore, we propose that the gut microbiome dysbiosis is involved in sepsis-induced coagulopathy. This project intends to prospectively observe the changes in gut microbiome dysbiosis and blood coagulation function in patients with sepsis before and after treatment, and explore whether the changes in gut microbiome dysbiosis promote the development of sepsis through coagulation disorders, provide new research perspectives for diagnosis and treatment for sepsis.
The performance of the microbiota is observed in all clinical and pathological stages of carcinogenesis, since its development, diagnosis and treatment, including prognosis and survival. However, it was found that there is a scarcity of studies on biliary microbiota and its relationship with hepatobiliopancreatic diseases. Therefore, further investigation is necessary, since reaching the biliary microbiota may suggest ways for studies of biomarkers, diagnoses, tests and therapies in hepatobiliopancreatic diseases. For this, bile samples will be collected in cases and controls patients to characterize the microbiota and its variations according to the disease.
Autism Spectrum Disorder (ASD) is characterised by an impairment of social interactions and communication, associated with repetitive behaviour and restrictive interests. Clinical phenotypes of this neurodevelopmental disorder are heterogeneous and surprisingly up to 70% of ASD patients have gastro-intestinal (GI) disorders, associated with ASD severity and influence by feeding disorders. Gut-brain axis seems to play a key role in neurodevelopment and ASD pathophysiology. Indeed an intestinal dysbiosis is observed in ASD, as well as intestinal inflammation and permeability. Aspecific inflammatory pattern suggests neuroinflammation processes in ASD. Neuroinflammation is involved in blood brain barrier (BBB) integrity and there are some arguments for a putative BBBimpairment in ASD. Nevertheless, no study has explored all together these parameters in ASD patients. Here we hypothesise that intestinal dysbiosis in ASD could lead to a BBB impairment through neuroinflammation processes. Furthermore, this association between intestinal dysbiosis and BBB impairment could be influenced by a lot of clinical characteristics, such as ASD severity or GI disorders presence. The principal aim of our study is to determine if the gut microbiota composition is associated with the BBB integrity in ASD. The secondary objectives are i) too identify in children with ASD some physiopathological pathways involved in this association, with a focus on associations betweenintestinal dysbiosis, intestinal permeability, intestinal permeability, the Th1/Th2 immune response, neuroinflammation and the BBB integrity; ii) to evaluate the influence of these associations on several clinical features of ASD such as ASD severity or GI disorders intensity; iii) to evaluate the influence of nutritional status on biological and clinical parameters. This study will assess a lot of clinical and biological parameters together, some of them were never explored in ASD children. It will allow to better understand ASD pathophysiology, to highlight new therapeutic pathway, and to promote personalised medicine.
This study aims to determine the effect of three factors (delivery type, feeding type and the use of two different dietary supplements) on rebiosis after disbiotic delivery. This is a randomized, single-blinded study with two parallel arms. Group 1 will receive L. reuteri (10^8 CFU) once a day, group 2 will receive B. longum and P. Pentosaceus (10^9 CFU) once a day.
