Filter by:The central hypothesis of this clinical trial is that, in extremely preterm infants, protein-enriched human milk diets compared to usual human milk diets during the first 2 weeks after birth increase fat-free mass (FFM)-for-age Z scores and promote maturation of the gut microbiome at term corrected age.
This is a pilot study designed to investigate the alterations in the gut microbiome that occur during the course of kidney transplantation, liver transplantation, allogeneic hematopoietic stem cells and mesenchymal stem cells transplantation in association with the clinical outcomes.
The demand for alternatives to dairy products has increased in recent years and a lot of proposals for vegetable milk and yogurt products have taken place in the market. Quinoa is a plant from South America that has growth in popularity in recent years as many sought out nutritious and healthier eating, the herb is known for its high nutritional value. It is complete protein source containing all the essential amino acids. If this herb were fermented with probiotic bacteria, there is a potential for a product that is lactose free, gluten free and cholesterol free. The probiotic potential of quinoa milk, fermented with food associated lactic acid bacteria will be investigated. This includes a study that examines how daily consumption of this vegetable drink changes the composition of the oral and intestinal flora. Therefore, healthy people are now seeking to participate in the study, which will be for just over 2 weeks.
Microbiome in patients affected by pancreatic ductal adenocarcinoma may present specific and identifiable patterns. These variations could affect the surgical outcome and increase the risk of life-threatening infections supported by multidrug-resistant bacteria. The identification of microbial signatures with tumor specificity may have a potential role in postoperative risk stratification. Variation of pancreatic, intestinal or bile microbiome and their relationship can be investigated and measured as promising tools in order to predict and overcome the clinical and infectious burden imposed by MDR infections. The prospect of a potential role for probiotics to promote competition against the pathogens and to improve the gastrointestinal barrier integrity has also been raised. Moreover, if the bacterial composition in human PDAC was confirmed to be distinct from that of the normal pancreas, microbiome variation could be used as a potential biomarker, to assess the potential for malignancy in precursor neoplastic lesions. However, we believe that a preliminary and explorative study is necessary. The study aims to outline the pancreatic microbiome of patients who undergo upfront PD for resectable PDAC and to characterize the possible association between bacterial composition and the occurrence of post-operative complications, particularly POPF and IC.
Enteral feeding tube (EFT) and component of feeding systems can serve as a reservoir of microorganisms, and the main reason is inappropriate hand hygiene practices. The aim of the project is to determine colonization of microorganisms on the EFT and other components and assess the relation between colonization and adherence to hand hygiene practices by healthcare workers in the intensive care unit. This prospective, observational and semi-experimental study will be conducted in one year. The project will be completed with healthcare workers and 51 patients who are feeding enteral route via nasogastric tube at least for three days. The researchers will provide training to healthcare workers in accordance with the World Health Organization (WHO) Hand Hygiene Guidelines. Hand hygiene behaviors of the participants will be observed and the question forms will be filled before and after training by researchers. The samples for microbial analysis will be collected from the EFT by sterile swaps.
To identify differences in the intestinal microbiota by metagenomics analyses between lean and obese subjects
Objective: The aim of this study was to investigate the effects of nutrition Training on mothers' nutrition pattern, breast milk and newborn intestinal microbiota. Materials and methods: The study was conducted as a non-randomized controlled experimental study. The population of the study consisted of mothers and their babies who delivered vaginally, breastfeeded their babies at the end of the second postnatal day and delivered at the maternity ward of the Malatya Training and Research Hospital Beydağı Campus. The sample of the study consisted of 120 mothers, 57 of whom were experimental and 63 of them were in the control group. In this study, a sub-sample of 15 mothers and their infants was selected and microbiota of breast milk and stool samples were examined. In the first interview with the mothers in the experimental and control groups, Participant Identification Form, BTSKF were applied as a pre-test and stool samples of breast milk and newborn were taken. Then, the mothers in the experimental group were given nutritional education. In addition, motivational messages were sent to mothers' phones once a week. MTS in the experimental and control groups were filled with BTSKF as an intermediate test at the first month and post-test at the third month and stool samples of breast milk and newborn were collected at the mothers' own homes. During these visits, nutrition counseling was given to the mothers in the experimental group.
The microbiome can affect skin health from the gut-skin axis, from environmental exposure, and topical treatments. Decreasing biodiversity of skin microbiota has been linked to inflammatory conditions, allergies, and skin health. This cross sectional study will be used to survey healthy volunteers and measure the density and diversity of skin flora of varying skin types. The aim of this study is to identify associations between the skin flora and characteristics of healthy skin types.
Microbiota contributes to the immunological, hormonal and metabolic homeostasis of the host. As in all natural orifices in the body, there is also a microbiota and mycobiota specific to the vagina. On the other hand, the sonographic short cervix in the second trimester of pregnancy is associated with preterm delivery, which may be an important cause of mortality and morbidity in the neonatal period. American Society of Obstetricians and Gynecologists (ACOG), British Royal Society of Obstetricians and Gynecologists (RCOG) and the American Society of Maternal Fetal Medicine (SMFM) suggest that the measurement of transvaginal sonographic cervical length at 20-24 gestational weeks for the screening of preterm birth. The aforementioned associations also recommend the use of progesterone in the treatment of women who diagnosed with short cervix by transvaginal ultrasonography due to the fact that progesterone is an effective medication in the prevention of preterm birth (Grade B). Previous vaginal microbiota studies have shown that some bacterial species such as Lactobacillus insers cause a predisposition to premature labor in women with a short cervix. However, the prominent lack in these studies is that the eukaryotic fungi in abundant vaginal flora have not been evaluated. On the other hand, it was already shown that progesterone treatment is able to prevent only 45% preterm birth in women with short cervical length. This observational prospective study thus aims to evaluate the variety of microbiota and/or mycobiota in pregnancies resulting in preterm birth and those who give birth at term. Although women with short cervical length receive progesterone regularly from the second trimester, the preterm birth may occur. In this study, the investigators also aim to evaluate the patterns of microbiota and mycobiota from vaginal swabs of women who had preterm birth with short cervical length and postpartum swabs of the placenta and fetal oral cavity.
All subjects will complete a 49-day, multi-phase feeding study to evaluate the effect of pea fiber supplementation on gut community structure and features of host biological state (plasma proteome/ metabolome). Subjects will be asked to continue to consume their habitual diet (free diet phase) for 4 days prior to being provided with a diet high in saturated fat (HiSF) and low in fruits and vegetables (LoFV) in the form of packed-out meals and snacks to consume for the following 45 days. Ten days after starting to consume the HiSF-LoFV diet, subjects will supplement their diet with pea fiber for a total of 21 days; the energy contribution from the HiSF-LoFV diet will be reduced accordingly to maintain energy needs during this time. After completing the pea fiber supplementation phase of the study subjects will revert back to consuming the HiSF-LoFV only diet for the final 14 days. Stool, urine and blood will be sampled periodically throughout.
