Wells and Enteric Disease Transmission
DiarrheaGastrointestinal Infection2 moreApproximately 40 million people in the US are served by private, and frequently untreated, wells. Our best estimate is that 1.3 million cases of gastrointestinal illnesses (GI) per year are attributed to consuming water from untreated private wells in the US, but in reality, there are no robust epidemiological data that can be used to estimate cases of GI attributable to these sources. We propose the first randomized controlled trial (RCT) to estimate the burden of GI associated with private well water. We will test if household treatment of private well water by ultraviolet light (UV) vs. sham (inactive UV device) decreases the incidence of GI in children under 5. We will also examine the presence of viral, bacterial, and protozoan pathogens in stool and well water from participants. These data will fill a knowledge gap on sporadic GI associated with federally-unregulated private water supplies in the US.

The present study aimed to investigate peritoneal dialysis-related infection, causative pathogens resulting in topical 2% mupirocin ointments period compare with 0.1% gentamicin cream period. Rate of catheter removal, time to first peritoneal dialysis-related infection after apply gentamicin cream.
Can the Relative Fecal Abundance of BLSE and the Digestive Microbiota be Predictive of the Risk...
Enterobacteria InfectionsAmong Enterobacteriaceae, the production of beta-lactamases (ESBLs) is the leading cause of multi-resistance. The first cases of ESBL-producing Enterobacteriaceae (E-ESBL) infections were described in the 1980s and subsequently experienced worldwide dissemination. Since the turn of the century, the prevalence of E-ESBL infections, especially among Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) has increased dramatically. The emergence of multidrug-resistant Enterobacteriaceae is currently a real public health problem. The European Antimicrobial Resistance Surveillance Network evaluated, among clinical strains, the rate of resistance to 3rd generation cephalosporins (C3G) at 9.5% for E. coli and 28% for K. pneumoniae. Numerous studies have shown that bacterial colonization is the prerequisite for the occurrence of many infections. However, the existence of prior colonization does not seem to be the only risk factor for the occurrence of a secondary infection. Therefore, in patients with multidrug-resistant Gram-negative bacillus gastrointestinal carriage there appear to be factors associated with the onset of infection. Several studies have examined the risk factors associated with E-ESBL-related infections in both community-based and healthcare-associated / nosocomial infections. Two main risk factors seem to be associated with E-ESBL infections: prior antibiotic therapy and the existence of invasive devices. A recent study, carried out on 1288 patients and aimed at validating a predictive score for the occurrence of ESBL-E bacteremia, demonstrated 5 factors associated with the appearance of E-ESBL-linked bacteremia. These factors were: (i) a history of colonization / infection with ESBL-E, (ii) age ≥ 43 years, (iii) recent hospitalization in a region with a high prevalence of ESBL-E, (iv) antibiotic therapy ≥ 6 days in the previous 6 months and (v) the existence of a chronic vascular access. Recently, a retrospective case-control study conducted in the United States by Augustine et al. Suggested that 5% of cases of bacteremia were related to ESBL-E. Few studies have looked at risk factors for infection in patients known to be colonized by the digestive system. In a retrospective case-control study, conducted outside the intensive care unit and including pediatric and adult patients, the authors identified 2 factors associated with the occurrence of Ec-ESBL infection in previously colonized patients. These two factors were the prior use of antibiotics with β-lactam antibiotics and β-lactamase inhibitor (s), and urinary catheterization. In intensive care hospital patients, the occurrence of ESBL-producing enterobacteriaceae infection appears to be a rare event, including in colonized patients. The work of Ruppé et al. showed a direct link between relative fecal abundance of EScher-producing Escherichia coli and prior antibiotic intake. This work also demonstrated a link between the value of the relative fecal abundance in Ec-ESBL and the occurrence of a urinary tract infection linked to the same clone. In particular, the authors found that women with a low relative fecal abundance rate (≤ 0.1%) had no risk of developing an Escherichia coli urinary tract infection. Conversely, the risk increased with the relative fecal abundance of Escherichia coli, but with a positive predictive value limited to 57% for relative fecal abundances between 10 and 100%.
Low-field Magnetic Resonance Imaging in Pediatric Post Covid-19
COVID-19COVID-19 Respiratory Infection1 moreSARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) is a new coronavirus and identified causative agent of COVID-19 disease. These viruses predominantly cause mild colds, but can sometimes cause severe pneumonia and pulmonary skeletal changes. By low-field gastric magnetic resonance imaging (NF-MRI), only a small number of structural, scarring changes were seen in a preliminary study of pediatric and adolescent patients with past SARS-CoV-2 infection. In contrast, however, extensive changes in ventilation and blood flow function of the lungs were seen. The long-term consequences and spontaneous progression of these changes on imaging are completely unclear. The aim of this study is to assess the course of these functional lung changes in pediatric and adolescent patients and to validate them with other standard clinical procedures.
Early Identification and Severity Prediction of Acute Respiratory Infectious Disease
Acute Respiratory InfectionSevere Pneumonia2 moreEarly identification and Severity prediction of Acute Respiratory infectious disease has become a top priority for clinicians at department of infectious and respiratory diseases after COVID-19 broke out. This is a multicenter, prospective, and randomized study, which aims to figure out the best way of early identification and severity prediction of acute respiratory infectious diseases. Patients with suspected acute respiratory infectious diseases will be enrolled into this study and received two different diagnostic pathways.
The Protective Effect of Mask Wearing Against Respiratory Tract Infections
COVID-19Respiratory Tract InfectionsIn this trial the researchers plan to recruit 4,000 volunteers to be randomly allocated either wearing face masks in public spaces where they are close to other people, or not wear face masks in such circumstances. For each participant the trial period is 2 weeks, after which they will be asked to complete a brief questionnaire which includes questions about whether they experienced the common cold, influenzas or COVID-19 symptoms during the trail period.
