Filter by:The aim of this study is to examine the relationship between oral microbiota and eating habits, sleep quality and hedonic hunger in adolescents.
The goal of this observational study is to learn about vaginal microbial characteristics in the patients under in vitro fertilization treatment. The study aims to address the following questions: (1) Is there any difference in microbial composition between the pregnancy and non-pregnancy groups? (2) Is there any differences in specific bacterial species between the two groups? (3) What are the favorable or unfavorable profiles of vaginal microbiota associated with achieving pregnancy? Patients will be asked to complete a questionnaire regarding their basic characteristics, and vaginal secretions will be collected via vaginal swab during frozen-blastocyst transfer procedures. The study will compare vaginal microbiota between pregnant and non-pregnant patients to assess its potential influence on clinical outcomes.
In this study, investigators seek to determine whether the timing of antibiotics given to mothers during an elective C-section affects the composition of their infant's gut microbiome. To do this, a randomized controlled trial (RCT) was carried out with women undergoing elective C-sections. These women were either given antibiotics before the skin incision (AB+) or after the umbilical cord was clamped (AB-).
The aim of the study is to evaluate the effectiveness of Hypochlorous Acid and Chlorhexidine as postsurgical antimicrobial agents in the treatment of severe chronic periodontal disease. The selected patients will be randomly divided into two groups of 16 each. Subjects in group I will undergo scaling and surgical root planing and will use mouthrinse with 0.05% HOCl for 7 days, after this they will mouthwash with 0.025% HOCl until day 21 and Subjects in group II will undergo scaling and surgical root planing followed by a rinse with CHX 0.2% for 7 days, after this they will mouthwash with 0.12% CHX until day 21. Null Hypothesis: There are no significant differences between hypochlorous acid and chlorhexidine in reducing plaque formation at 7, 21 and 90 days of evaluation. There are no significant differences between HOCl and CHX in the elimination or reduction of periodontopathogenic microorganisms at 7, 21 and 90 days. Alternative hypotheses: There are significant differences between hypochlorous acid and chlorhexidine in reducing plaque formation at 7, 21 and 90 days of evaluation. There are significant differences between HOCl and CHX in the elimination or reduction of periodontopathogenic microorganisms at 7, 21 and 90 days.
Within the Denali study the effect of 3 weeks intervention with GOS on the abundance of Bifidobacterium in faecal samples will be investigated.
The goal of this interventional study is to learn about nasal microbiome and viral infections in newborns hospitalised in neonatology. The main questions it aims to answer are : - how often are newborns infected by viruses in neonatology ? - how does the microbiome develop during first weeks of life ? - how does microbiome and viruses interacts together ? - is there a link between viral infection, microbiome, and medical complications during hospitalisation in neonatology ? Participants will have a nasal swab taken each week during their hospitalisation in neonatology, and researchers will take medical data from the medical chart.
The aims of this study were: 1. Observation of dynamics in oral microbiota and its association with the incidence of HAIs and VAP in mechanically ventilated COVID-19 patients in an ICU setting 2. Evaluation of the incidence of HAIs and VAP and their association with oral bacteriobiota in mechanically ventilated COVID-19 patients in an ICU setting 3. Assessment of impact of different oral hygienic procedures on oral microbiota, the incidence of HAI and patients' safety in mechanically ventilated COVID-19 patients in an ICU setting approaches to oral care in an ICU setting Intervention of oral hygienic procedures implemented in study: Patients were divided into 2 groups depending on the oral care procedure: 1. Standard oral procedure (cleaning and moisturizing of oral cavity, suction of excess fluid) 2. Extended oral procedure (cleaning and moisturizing of oral cavity, teeth brushing, suction of excess fluid)
This study investigated the effects of a proprietorial herbal supplement, Turmeric Brainwave (now Mind focus), on cognition, mood and the microbiome in older adults experiencing subjective memory decline, following 90 days supplementation.
This prospective cohort study was conducted in the Christiana Care Health System Neonatal Intensive Care Unit. It occurred at two time periods: Time period 1 included infants admitted to the traditional, open bay NICU. Time period 2 included infants admitted to the new private, single family room NICU. There was a 3 month period between Time period 1 and Time period 2 to ensure that there was no patient overlap. Stool samples and environmental samples were collected at 1 and 4 weeks after birth in both time periods. The objective of this study was to establish the gastrointestinal microbiome of infants born at less than 32 weeks gestation admitted to the exiting open bay NICU and compare it to the gastrointestinal microbiome of infants born at less than 32 weeks admitted to the new private, single family room NICU.
PrePhage - Fecal bacteriophage transfer for enhanced gastrointestinal tract maturation in preterm infants This pilot triol has the primary goal of demonstrating the safety of transferring viruses and proteins from healthy term infants to preterm infants born between gestational age (GA) 26 + 0 and 30+6. The long-term goal is to develop a safe and effective treatment to prevent the severe gut disease called necrotizing enterocolitis (NEC). NEC is a common disease in neonatal intensive care units affecting 5-10% of all admitted patients. 15-30% of the affected children die from the disease, and many of the survivors suffer from the effects of extensive gut surgery. While the disease is caused by many different factors, recent research has shown the gut microbiome to be a central factor in the development of NEC. Furthermore, in the recent years special viruses called bacteriophages have shown potential in the treatment of various diseases. By collecting feces from healthy, term infants and filtering it thoroughly, the investigators can provide a treatment that contains practically only viruses, proteins and nutrients. It is our belief that giving the preterm infants a mix of viruses including bacteriophages will prevent NEC. To do this, the investigators will go through 3 stages: Recruiting and following healthy donor infants to study the microbiota and use feces from them to donate in stage 2 and 3 Examining the safety of the treatment as well as how it works in preterm piglets STAGE 3 will be performed only if stage 2 shows no serious risks for the infants Testing the treatment in preterm infants. 10 preterm infants will receive the treatment and 10 preterm infants will receive placebo. The investigators expect to see no serious side effects to the treatment. The investigators hope, but do not expect to be able to see a beneficial effect of the treatment. If this pilot trial shows promising results, it will be followed be a larger clinical trial.
