Filter by:As the global availability of vaccines increases, and reaches areas disproportionately affected by arsenic and malnutrition, resolving questions about potential environmental and biologic barriers to maternal immunization has become increasingly urgent. It is not known whether arsenic, a known developmental toxicant, can alter maternal immune responses to vaccination and whether exposure to arsenic during pregnancy can impair the transfer of maternal vaccine-induced antibody to the newborn. Moreover, factors known to affect arsenic metabolism and toxicity outcomes, particularly micronutrients critical in one-carbon metabolism, have not been evaluated in studies of arsenic immunotoxicity and vaccine-induced protection in mothers and their newborns. The objective in this study is to investigate whether maternal arsenic exposure and one-carbon metabolism micronutrient deficiencies alter maternal and newborn measures of vaccine-induced protection, respiratory morbidity, and systemic immune function following influenza vaccination during pregnancy.
Background: Lymphoma is a type of blood cancer. Blood cell transplant can cure some people with lymphoma. Researchers want to see if they can limit the complications transplant can cause. Objective: To test if a stem cell transplant can cure or control lymphoma. Also to test if new ways of getting a recipient ready for a transplant may result in fewer problems and side effects. Eligibility: Recipients: People ages 12 and older with peripheral T cell lymphoma that does not respond to standard treatments Donors: Healthy people ages 18 and older whose relative has lymphoma Design: Participants will be screened with: Physical exam Blood and urine tests Bone marrow biopsy: A needle inserted into the participant s hip bone will remove marrow. Donors will also be screened with: X-rays Recipients will also be screened with: Lying in scanners that take pictures of the body Tumor sample Donors may donate blood. They will take daily shots for 5 7 days. They will have apheresis: A machine will take blood from one arm and take out their stem cells. The blood will be returned into the other arm. Recipients will be hospitalized at least 2 weeks before transplant. They will get a catheter: A plastic tube will be inserted into a vein in the neck or upper chest. They will get antibody therapy or chemotherapy. Recipients will get the transplant through their catheter. Recipients will stay in the hospital several weeks after transplant. They will get blood transfusions. They will take drugs including chemotherapy for about 2 months. Recipients will have visits 6, 12, 18, 24 months after transplant, then once a year for 5 years.
The Huizhou mother-infant cohort was set up to investigate the effect of dietary factors and environmental exposures during pregnancy on health consequences of mothers and offsprings in Huizhou, China.
This is a study to assess the effect of dietary zinc supplementation to mitigate biomarkers of metal toxicity in exposed tribal populations.
To determine if artificial intelligence allow to detect lymphocyte subpopulations specific of diseases (such as primary Sjogren' syndrome and systemic lupus erythematosus) among patients with suspicion of autoimmune diseases.
This study examines an intervention to promote effective, evidence-based care and de-implement inappropriate therapies for COPD in HIV-infected (HIV+) patients. The intervention facilitates specialist support of primary care, which includes infectious disease (ID) physicians who serve as the primary care providers (PCP) for their HIV+ patients in the ID clinic. Rather than relying on referral-driven specialty care which may be a barrier to access, pulmonologists will proactively support ID providers to manage a population of HIV+ patients with COPD, delivering real-time evidence-based recommendations tailored to the individual HIV+ patient in the form of an E-consult.
This is a multicentre prospective audit to determine the incidence of immunodeficiency in children with IPD. Aims and/or research question of the project 1. To determine the incidence of primary immunodeficiency in children >2 years who present with IPD 2. To determine the types of immunodeficiency associated with IPD in children
The aim of the project is to study neonatal immune dysfunction associated to the risk of newborn sepsis in a malaria endemic area in Benin.
This is an open-label, multicenter, Phase 2 study to determine the safety, PK, and efficacy of lisocabtagene maraleucel (JCAR017) in subjects who have relapsed from, or are refractory to, two lines of immunochemotherapy for aggressive B-cell non-Hodgkin lymphoma (NHL) in the outpatient setting. Subjects will receive treatment with JCAR017 and will be followed for up to 2 years.
B7451029 is a Phase 3 study to investigate PF-04965842 in adult patients who have moderate to severe atopic dermatitis and use background topical therapy. The efficacy of two dosage strengths of PF-04965842, 100 mg and 200 mg taken orally once daily will be evaluated relative to placebo over 12 weeks. The efficacy of the two dosage strengths of PF-04965842 will be compared with dupilumab in terms of pruritus relief at 2 weeks. The two dosage strengths of PF-04965842 and dupilumab 300 mg injected subcutaneously once every two weeks (with a loading dose of 600 mg injected on the first day) will also be evaluated relative to placebo over 16 weeks. The safety of the investigational products will be evaluated over the duration of the study. Subjects will use non-medicated emollient at least twice a day and medicated topical therapy such as corticosteroids, calcineurin inhibitors or PDE4 inhibitors, as per protocol guidance, to treat active lesions during the study. Subjects who are randomized to receive one of the two dosage strengths of PF-04965842 will also receive placebo injectable study drug every two weeks until Week 16 and then will continue on receiving only the oral study drug for 4 weeks. Subjects who are randomized to receive dupilumab injections every two weeks will also receive oral placebo to be taken once daily until Week 16 and will then continue to receive only the oral placebo for 4 weeks. Subjects who are randomized to the placebo arms, will receive both daily oral placebo and injectable placebo every two weeks until Week 16, after which they will receive either 100 mg or 200 mg of PF-04965842 taken orally once daily for 4 weeks, dependent upon which arm they have been allocated to. Eligible subjects will have an option to enter a long-term extension study after completing 20 weeks of treatment.
