Risk Factors, Clinical Characteristics and Outcomes of Acute Infection With Coronavirus 2019 (COVID-19)...
Corona Virus InfectionPediatric Cancer2 morePatient are being asked to provide respiratory and blood samples for a clinical research study because the patients have a virus called the novel coronavirus, or SARS-CoV-2, that causes the disease known as Covid-19. Investigators do not know a lot about this virus, including all the ways it travels from person to person. Investigators also do not know if a person will get sick or not from the virus after being in close contact with someone who has the virus. Because of this, investigators are performing research on the virus found in respiratory secretions to get more information on how investigators can best detect and treat this new virus in the future. Primary Objective To determine the clinical characteristics and outcomes of Covid-19 in children. To characterize the clinical risk factors of Covid-19 in children.. Secondary Objectives To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. To evaluate the duration of SARS-CoV-2 viral shedding in children. Exploratory Objective

Infectious Pseudochromdrosis Caused by Bacillus Cereus
Infectious DiseaseBacterial Overgrowth1 moreTwelve patients with blue sweat (infectious pseudochromhidrosis) caused by Bacillus cereus.

Study on Diagnosis Value of mNGS Technology Among Diabetic Patients With Pulmonary Infections
Diabetes MellitusPulmonary InfectionFocusing on patients with diabetes complicated with pulmonary infection, the purpose of this study is: 1) to identify the epidemiology, etiologic spectrum and status of diagnosis and treatment; 2) to explore the lower respiratory microenvironment and host immune response and then make an application in clinic.

Study on the Application of Saliva EBV-DNA Detection in EBV Infection Related Diseases
EBV InfectionThis study is a single-center, prospective, observational clinical study to evaluate the Application of saliva EBV-DNA Detection in EBV Infection Related Diseases

Congenital CYtoMEgalovirus Infection in VIEtnam (CYMEVIE)
Prenatal InfectionCongenital Infection1 moreTo estimate the prevalence of congenital CMV infection in Vietnamese neonates and relating morbidity within 2-year follow-up. Along with evaluating the predictive value of the presence and the level of CMV replication in the first trimester in a highly seropositive population

COVID-19 Associated Pulmonary Aspergillosis (CAPA) and Other Invasive Fungal Infections (IFI)
Covid19Aspergillosis1 moreThe purpose of this study is to identify the number of individuals with severe CoVID who require ventilator support and who develop serious fungal infections. The study is an observational study, meaning that we are not providing any intervention that does not involve usual standard of care. Our chief goal is to find evidence of fungal infection by using traditional, approved methods of diagnosis, but by applying these methods in the same way and frequency among all study participants. We will be looking especially for evidence of a fungal infection known as Aspergillus, which can causes a serious lung infection called invasive aspergillosis (IA).

Overcoming Geography With Technology: Medical Drones Project
Sexually Transmitted Infections (Not HIV or Hepatitis)HIV Infections1 moreIn this study, the investigators shall evaluate the use unmanned air vehicles (medical drones) to deliver ART to adult patients eligible/enrolled in community DSD models in Bufumira Islands, Kalangala district. The geography of the islands is ideal for this project because of the flat landscape and water coverage. The investigators hypothesize that the use of drones would be acceptable to patients and stakeholders, reduce facility drug stock outs, increase retention in care by 10% in intervention (at 12 months) compared to the control health centres and be cost neutral (to the patients and health sector perspectives). The investigators will also undertake evaluation of an efficient sample delivery system using medical drones especially for expansive rural areas like Moyo and Adjumani.

KIDney Injury in Times of COVID-19 (KIDCOV)
SARS-CoV InfectionCovid193 moreThere is an unmet need to evaluate the impact of sub-clinical/mild COVID19 disease in the outpatient setting on prevalent and incident renal injury, as this data is currently unavailable. To capture the diversity of race/ethnic risk and COVID19 related municipal shelter-in-place guidance, the investigators will enroll COVID19-negative and COVID19-positive samples balanced by race/ethnicity from 3 different states, California, Michigan, and Illinois. Study endpoints will be assayed from urine samples mailed to the study team at 2, 6, and 12 months after their date of PCR test, with no requirement for these individuals to leave their homes to participate.

Assessment of the Ocular Microbiome in Health and Disease
Microbial ColonizationEye Diseases1 moreThe objective of this application is to illustrate the core constituents of the ocular surface microbiome, describe factors that promote colonization, and assess the ocular microbiome's role in the health of the anterior segment. We will conduct a prospective, observational cohort study, including a longitudinal analysis of the ocular microbiome in adults.

Metabolic and Infectious Diseases in La Réunion (the REUNION Population-based Study)
Infectious DiseaseCardiovascular Diseases2 moreThe aim of the present study is to determine the prevalence of cardiometabolic and infectious disease in La Reunion (french oversea department and region of France). Known or suspected risk factor for these diseases will also be assessed, such as microbiota, cognitive impairement, social inequalities, and genetics.
