Filter by: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.
The aim of this study is to evaluate the colonization efficacy of probiotic lozenges containing dairy and dairy free probiotic Streptococcus salivarius M18, in healthy adults
The aim of this study is to evaluate the colonization efficacy of probiotic lozenges and powders containing specific prebiotics in healthy adults
To evaluate the colonisation efficacy (i.e. ability of the probiotic bacteria to remain in your mouth) of a fast melt powder that quickly dissolves in the mouth. The fast melt powder will contain a Streptococcus salivarius probiotic and the study is to be done in healthy adults.
The purpose of this study is to evaluate the effects of oral administration of probiotic at 9 log colony forming unit (CFU)/day on vaginal microbiota profiles compared to placebo via the use of vaginal self-swab microbiota profiling.
Introduction: Oral candidiasis is an infectious disease caused by the growth of Candida colonies and their penetration into oral tissues when physical barriers and host defenses are weakened. It constitutes one of the most common pathologies within the field covered by Dentistry. Candida infections are found in at least 80% of AIDS patients and in a third of HIV infection cases. Systemic diseases such as diabetes and a wide pharmacological arsenal to which the general population is subjected, are other causes of the increase in the prevalence of this disease. In addition, the high prevalence of oral sequelae (hyposialia) in the population over 65 years of age, due to the specific characteristics of this age group, such as multiple pathologies and drug use, explains the presence of this disease in this segment. of the population One of the great difficulties for the study of this disease is the diversity of predisposing factors, which do nothing but throw greater confusion into the results of the different works. Objective: To evaluate the reduction/suppression of signs and symptoms of oral candidiasis in patients treated with head and neck RT, users of Vacucis or Placebo. Material and method: Patients will receive information regarding the trial and, if they meet the inclusion criteria and agree to participate in it, they will sign the informed consent. All patients will be informed following the usual care practice of the characteristics of their candidiasis infection as well as the possibilities and alternatives of treatment and their respective efficacy. A descriptive analysis of the sample in terms of prevalence will be carried out. Categorical variables will be described as frequency and percentage and continuous variables as mean and standard deviation or median and interquartile range depending on their adjustment to normality, which will be calculated with the Kolmogorov-Smirnov test. To study the effect of the vaccine on the evolution of candidiasis, the Chi-square test, Student's t test or the non-parametric Mann-Whitney test will be used. The association of prevalence with CFU in both groups will be analyzed using the ANOVA test. Those values of p < 0.05 will be considered significant.
The purpose of this investigation is to better understand the wound microbiome in burn wounds and the role it plays in outcomes and complications related to treatment.
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.
