Filter by:This is an observational case-control study which objective is to analyse differences in intestinal microbiota between patients with and without arterial stiffness, measured by pulse wave velocity. It will take place in two different research units located in Portugal and Spain.
Depending on recent studies in literature the investigators aimed to compare whether gastrointestinal tolerance differs between infants fed with palm olein containing or palm olein free formulas. Besides it is showed that palm olein containing formulas decreases the absorption of fat and calcium by forming insoluble calcium soaps. So it is suggested that intestinal flora might be affected as a reason of these specialties. This study also aimed to investigate with culture-independent methods whether feeding infants with palm olein free formula results in the modification of their intestinal microbiota in such a way that is similar to breastfed ones.
The changes in the organisms making up the gut microbiota in infants who are taking anti-acid reflux medications (histamine 2 receptor antagonists) as compared to infants who are not taking these medications is not well-studied or understood. Whether these medications change the gut microbiota and microbiome, and what that change may imply for children on these medications, is the focus of this study.
Pilot study to evaluate the effect of the strain Lactobacillus PS11610 on the microbiota of the female and male genital tract in couples with fertility problems. Couples who have started treatment for artificial insemination or who are on the waiting list for an invitro fertilization treatment will be invited to participate. The estimated duration of the study will be 7 and a half months.
The aim of this study is to assess influence of probiotic Lactobacillus reuteri DSM 17938 on formation of gut microbiota in infant born by Caesarean section. It is anticipated that daily using of probiotic Lactobacillus reuteri DSM 17938 can prevent development of early dysbiosis of gut microbiota induced by Caesarean section.
The specific aim for this project will be to investigate a cranberry beverage as a means to restore balance in terms of the relative proportions of the various bacteria that inhabit the large intestine.
Objectives: The gut microbiota plays pivotal role in the maintenance of human health. There are numerous factors, including the mode of delivery, that impact early gut colonization. Recent research focuses on probiotics' use in prophylaxy of gut dysbiosis in the newborns delivered by CS. We aimed to investigate whether a probiotic supplement in the newborns delivered by CS alter the pattern of gut colonization and has effect on decreasing risk of dysbiosis. Methods: a prospective, randomized trial with a control group. 150 newborns, born in 38-40 gestational age, delivered by CS were included to the study. They were randomized into 2 groups- interventional supplemented with the probiotic containing Bifidobacterium breve PB04 i Lactobacillus rhamnosus KL53A (FFBaby, IBSS BioMed SA, Poland) and control. Stool samples were obtained on 5th and 6th day of life and after one month of life, and analyzed microbiologically in the lab. Bacterial colonies' genre and species were next identified and quantified.
Prospective interventional study of the effect of PPI on the duodenal microbiome in healthy volunteers and functional dyspepsia patients
Obesity is characterized by an underlying inflammatory state in which various inflammatory signaling molecules, termed cytokines, affect metabolic processes central to type 2 diabetes and cardiovascular disease; leading causes of disability and death in Ontario. Such obesity-associated inflammation is partly due to the movement of endotoxin (i.e. lipopolysaccharide (LPS), a cell wall component of Gram-negative bacteria) from the gut microbiota to the blood, resulting in elevated blood levels of LPS (a condition termed metabolic endotoxemia) that stimulates inflammation. Digestion of a high-fat meal increases blood LPS and is subsequently associated with inflammation and metabolic impairments. However, in this context, little is known about how the consumption of bioactive-rich foods, such as whole apples, can improve impaired inflammatory and metabolic responses in overweight and obese individuals. Apples are a key commodity to study given that they are Ontario's predominant fruit crop with the apple industry valued at approximately $400 million, they require little food preparation, and they are common in the diet year-round. There are some, but limited, reports of potential apple-induced health benefits related to reductions in inflammation and improved metabolic responses in lean/healthy individuals, but work in overweight and obese individuals is especially lacking. Thus, to address the gap in our understanding of how daily apple intake may improve the health consequences of obesity, we will conduct a randomized clinical trial in which overweight and obese adults will consume three Ontario-grown Gala apples (approximately 300 g) as part of their typical diet in one sitting (i.e. acute consumption) and/or daily for six weeks (i.e. chronic consumption). The Acute Apple Consumption phase of the study will follow a randomized crossover design in which participants' rate of gastric emptying, efficacy of dietary lipid digestion and absorption, and production of inflammatory cytokines and biomarkers of metabolism will be assessed before and after consuming a high-fat meal (designed to provide 1 g fat/kg body weight) with or without three apples in one sitting. The Chronic Apple Consumption phase of the study will follow a randomized, controlled, parallel-arm design in which participants' (fasting) production of inflammatory cytokines and biomarkers of metabolism, as well as their gut microbiota profile, will be assessed before and after consuming three apples (or no apples) daily for six weeks. We hypothesize that the consumption of three whole apples in one sitting and daily for six weeks will improve these parameters in overweight and obese individuals at risk of developing chronic metabolic diseases.
The Prebiotics in Peritoneal Dialysis trial is a non-randomized, open-label, crossover study of p-inulin for patients with end-stage renal disease treated with peritoneal dialysis.
