Asymptomatic and Pre-symptomatic Transmission of SARS-CoV-2 in a Community Congregant Setting

COVID-19SARS-CoV2 Infection

The overall aim of this study is to measure how transmission of COVID-19 occurs in communities - including the role of super spreaders and/or identifying conditions that may increase transmission risk, with a focus on congregant situations. In order to identify how presence of symptoms and behavior affects the transmissibility of the virus, the investigators will measure SARS-CoV-2 in exhaled breath of asymptomatic and symptomatic persons using polyvinyl alcohol (PVA) test strips embedded in face masks (Face Mask Sampling- "FMS") - an innovative, non-invasive method for detection of SARS-CoV-2 in exhaled air.

SKin and Soft Tissue Necrotizing INfections in the Intensive Care Unit: a Prospective Multi-national...

Necrotizing FasciitisFournier Gangrene1 more

Necrotizing soft-tissue infections (NSTI) are rare and life-threatening bacterial infections characterized by subcutaneous tissue, fascia or muscle necrosis. Few prospective studies have been performed and our current knowledge on NSTI is mostly derived from retrospective single center studies. The "SKin and soft tissue necrotizing INfections in the ICU" (SKIN-ICU) study is a multinational prospective non-interventional cohort study that will include patients admitted to the ICU/intermediate care unit for NSTI or not. The objectives of the study are : To assess hospital (i.e., ICU and hospital mortality) and medium-term (day-90 mortality, functional outcomes and health-related quality of life scores, HR-QoL) outcomes To report the clinical presentation and microbiological epidemiology of NSTI and identify independent prognostic factors of mortality and altered quality of life

Evaluation, Treatment and Monitoring of Patients With a Known or Suspected Parasitic Infection

MalariaIntestinal Worms3 more

The purpose of this study is to evaluate, treat and follow patients with parasitic infections. People with a known or suspected parasitic infection who are at least 1 year old may be enrolled. This study does not involve any experimental treatments. Participants will have a physical examination and laboratory tests on blood, stool, or urine. Blood samples may be collected at regular intervals, but no more than 450 ml (15 ounces) of blood will be drawn from adults, and no more than 7 ml (1-1/2 teaspoons) per kg (2.2 pounds) of body weight from children, in any 6-week period. Other tests may include x-rays, electrocardiogram (EKG), or tissue biopsy (surgical removal of a small tissue sample), depending on the individual s condition. Patients may be offered treatment or may be referred to another study that is more appropriate for the problem. Any treatment provided in this study will be according to standard medical practice for the patient s specific medical problem. Patients responses to treatment will be evaluated at regularly scheduled clinic visits. The length of time between visits and the total duration of the study for a given individual will be determined by the study doctor, based on that person s medical condition. ...

Host Response to Infection and Treatment in Filarial Diseases

FilariasisHelminthiasis3 more

This study will evaluate and treat patients with filarial infections to explore in depth the immunology of the disease, including susceptibility to infection, disease development, and response to treatment. Filarial infections are caused by parasitic worms. The immature worm (larva) is transmitted to a person through a mosquito bite and grows in the human body to 2 to 4 inches in length. Although many of these infections do not produce symptoms, especially in the early stages of infection, others can have serious consequences, including swelling of the limbs or genitalia, allergic-lung problems, skin rash, eye inflammation that can lead to blindness, and heart disease. This protocol does not involve any experimental diagnostic procedures or treatments, and will use only procedures employed in the standard practice of medicine. Persons between 3 and 100 years of age diagnosed with or suspected of infection with Wuchereria bancrofti, Bugia malayi, Onchocerca volvulus, Loa loa, or other parasitic worms may be eligible for this study. Participants will have routine tests to determine the specific type of filarial infection. These may include special tests of the lungs, skin or heart, depending on the type of parasite suspected. Patients with skin reactions may have a "punch biopsy" to examine a small piece of affected skin. For this procedure, an area of skin is numbed with an anesthetic and a small circular area, about 1/3-inch in diameter and 1/2-inch thick, is removed using a sharp cookie cutter-type instrument. Some patients may require bronchoalveolar lavage. For this procedure, the mouth and throat are numbed with lidocaine jelly and spray and, if needed, a sedative is given for comfort. A small plastic tube is placed in a vein to give medications. A pencil-thin tube is then passed through the nose or mouth into the lung airways to examine the airways. Salt water is injected through the bronchoscope into the air passage, acting as a rinse. A sample of the fluid is then withdrawn and examined for infection, inflammatory cells and inflammatory chemicals. (Bronchoalveolar lavage is done only if medically necessary and only on patients 21 years or older.) Once the diagnosis is established, standard treatment will be instituted with either diethylcarbamazine or ivermectin, depending on the type of infection. Additional procedures for research purposes include: Extra blood draws to study immune cells and other immune substances. (This is the only research procedure that will be done in - More frequent and extensive follow-up evaluations than usual for routine care. They will include physical examination and blood studies. Urine collections at specified periods, possibly including 24-hour collections. Skin tests to examine the body s reaction to allergens-common environmental substances, such as cat dander or pollen-that cause an allergic reaction. The test is done in one of two ways: either the skin is lightly scratched and an allergen extract is placed over the just-broken skin, or a very fine needle is used to inject a small amount of allergen under the skin. In both methods, the site is monitored for swelling or hives in the next 48 hours. Leukapheresis (only on patients 21 or older ) to collect quantities of white blood cells. Whole blood is collected through a needle in an arm vein, similar to donating blood. The blood circulates through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body, either through the same needle or through another needle in the other arm.

Study of the Aortic and Large Arterial Vessel Infections

Aortic Infections and InflammationsMycotic Aneurysm2 more

Aortic or large arterial vessel infections are rare but serious infections. Their management is based on French and American expert opinions. The quality of evidence supporting these guidelines is low because most publications on the subject correspond to case series and few interventional studies have been performed to validate their management. However, referral centres for vascular surgery are frequently solicited to give their opinion on patients suffering from mycotic aneurysms. In addition, the last few decades have seen the improvement of vascular surgery techniques allowing the management of more and more patients, often elderly and comorbid. There has therefore been an increase in the incidence of infectious complications associated with this care. It is therefore essential to participate in research on aortic and large arterial vessel infections. For this, a monocentric cohort study seems to be an essential first step to better understand the polymorphism and complexity of these patients.

Role of Neutralizing Antibodies in the Prediction and Treatment of BK Virus Infection in Hematopoietic...

BK Virus Infection

The BK virus (BKV) belongs to the Polyomaviridae family. The primary infection, generally asymptomatic, occurs during childhood. The virus then persists in latent form in the body, mainly in the epithelial cells of the kidney and urinary tract. Cellular immunosuppression favors BKV replication. It is responsible for pathologies of the renal-urinary tract such as BKV-associated nephropathy (BKVAN) in kidney transplant recipients, hemorrhagic cystitis (HC) in hematopoietic stem cell (HSC) recipients or ureteral stenosis. To date, there is no specific antiviral treatment against BKV. The management of patients is essentially symptomatic and requires a multidisciplinary approach. It is therefore necessary to identify early prognostic markers for the occurrence of CH and to develop new therapeutic strategies.
