Wells and Enteric Disease Transmission Trial (WET - Trial)
Gastrointestinal InfectionRespiratory Viral InfectionApproximately 40 million people in the US are served by private wells, many of which are untreated. The investigators estimate that 1.29 million cases of gastrointestinal illness (GI) per year are attributed to consuming water from untreated private wells in the US. These cases of GI can cause a significant burden in terms of health care costs and lost work/school days, as well as increased risk to developing longer term health complications. This impact is magnified when accounting for vulnerable populations such as children under the age of 5, the elderly and the immunocompromised. The investigators are preparing to conduct the first household randomized controlled trial (RCT) to investigate whether consuming well water treated by ultraviolet light (UV) compared to consuming untreated private well water decreases the incidence of self-reported gastrointestinal illness and respiratory infections in children under 5. The investigators will collect illness symptom data using a combination of weekly text messages and online illness questionnaires.
Consitution Of A Biological Collection From Samples From The Gut Microbiote In Patients Having A...
Bone and Joint InfectionOptimal surgical therapy (debridement in chronic osteomyelitis; device exchange in patients with chronic prosthetic joint infection [PJI]) could be sometimes non-feasible, especially in the elderly population. Therefore, a medical therapy with oral prolonged suppressive antibiotic therapy (PSAT) seems to be an option to prevent recurrence and prosthesis loosening. Unfortunately, some patients are infected with resistant pathogens for which oral antibiotics are not suitable. Subcutaneous (SC) administration of injectable intravenous antibiotics as PSAT could be a convenient way to limit catheter-related complications and facilitate ambulatory care. However, there are few data concerning the development of resistance under subcutaneous prolonged treatment with betalactamine. The aim of this study is is just to constitute a biological collection from samples from the GUT microbiote in patients having a bone or joint infection treated by a suppressive subcutaneous antibiotherapy with betalactamine. Later analysis will be led on those samples to detect the acquisition of resistance or not.
Acute Infection in Mitochondrial Disease: Metabolism, Infection and Immunity During the COVID19...
Mitochondrial DiseaseBackground: Mitochondrial disease is a rare disorder. It can cause poor growth, developmental delays, muscle weakness, and other symptoms. The disease is usually inherited. It can be present at birth or develop later in life. Infection is a major cause of disease and death in people with this disease. Researchers want to learn more about how infection and the declining health of people who have this disease may be related to the COVID-19 pandemic. To do this, researchers will study the DNA of people who become ill with suspected or confirmed coronavirus. Their DNA will be compared to the DNA of their family members. Objective: To learn more about how genes may play a role in how COVID-19 affects people with mitochondrial disease. Eligibility: People age 2 months and older with mitochondrial disease and a suspected or confirmed diagnosis of COVID-19.<TAB> Design: Participants will complete a questionnaire about their health history. Their medical records may be reviewed. They will give a blood sample. If the participant becomes ill, they may have a videoconference with a doctor or nurse at the NIH to perform a physical exam. They may be contacted after their illness to give updates on their health. They may be asked to give extra blood samples or complete extra questionnaires. Participants genetic data will be put into a database. The data will be labeled with a code and not their name. The data will be shared with other researchers. Participation lasts about 1 year. This may be extended if the participant is very ill.
The Microbiome of Pancreatic Cancer: "PANDEMIC" Study
Microbial ColonizationPancreas Cancer2 moreMicrobiome 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.
A Cost Effective and Time Saving Blood Test to Detect Six Human Bloodborne Infectious Diseases
HIVViral HepatitisThe consortium will develop a new in vitro diagnostic (IVD) test to screen donated blood for bloodborne infectious pathogens, saving blood banks time and costs required for analysis of mandatory pathogens. The IVD test is a multiplex immunoassay that simultaneously screens for six bloodborne infectious diseases per blood sample. In this project, a mix of diagnostic protein markers will be developed and validated to lowdown an IVD test ready for commercial scale-up and CE-IVD certification.
Early Protein Supplementation in Extremely Preterm Infants Fed Human Milk
Prematurity; ExtremeFeeding Disorder Neonatal3 moreThe 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.

InfluenCEF Study: Study on the Headache Associated With Influenza Infection
Headache DisordersInfluenza -Like Illness3 moreThe goal of this observational analytic study with a cohort desing is to evaluate the epidemiology, risk factors and clinical phenotype of headache during Influenza infection. The study will be done in collaboration with the Healthcare Sentinel Network of Castile and Leon (Red Centinela Sanitaria de Castilla y León, RCSCYL) and the National Influenza Center of Valladolid (CNGV). First, the historical data of the VIGIRA network of the 2010-2022 flu seasons will be analyzed, assessing the epidemiology and risk factors of headache during Influenza infection; and second, a study with a case series design with prospective follow-up will be carried out for the incident cases of the 2022-2023 and 2023-2024 Influenza seasons, evaluating the clinical phenotype and the duration of the headache.
Prospective Observational Study on the Incidence of Opportunistic Fungal Infections
Pneumocystis Jirovecii InfectionPneumocystis3 moreCorticosteroids exposure is a common risk factor for invasive fungal infections. Systemic corticosteroid therapy treats several medical conditions, including rejection in solid organ transplant recipients, malignancy, and autoimmune or inflammatory diseases. Corticosteroid exposure is a well-known risk factor for developing PJP. Still, it remains unclear how prior corticosteroid exposure influences the presentation, severity, and mortality of opportunistic fungal infections. The investigators aim to prospectively characterize the corticosteroid use as a dose response to inform risk of invasive fungal infections.
