PET Imaging and Lymph Node Assessment of IRIS in Persons With AIDS

A paradoxical, often inflammatory, immune response after the introduction of antiretroviral therapy. With only a few notable exceptions of cryptococcal IRIS experiments in which cerebrospinal fluid samples were collected and evaluated, most pathogenesis studies to date have been done in peripheral blood. This is a two-arm natural history survey designed to determine the incidence, predictors, and pathogenic mechanisms of IRIS in HIV-1-infected adults. 140 patients who are ART-naive with CD4+ T cell counts of 100 cells/mm3. Any CD4+ T cell count will be recruited by the IRIS arm, which will enroll 60 people who are ART-treated and meet IRIS-related criteria. If the IRIS event is confirmed, the IRIS arm will be followed for 48 weeks after enrollment, as well as an optional extension up to week 96.

Magnetic Sentinel Lymph Node Mapping in Gastric Cancer, Safety and Feasibility Clinical Trial

Will a negative SLN accurately predict the negativity of the other LNs? To investigate the reliability of this procedure by correlating sentinel lymph nodes to determine pathological Lymph node -positive status, i. e. Comparing to standard examination with just one H&E stain alone, we were able to determine the diagnostic value of additional hematoxylin and eosin sections and immunohistochemistry to determine sentinel lymph nodes. Patients are admitted to FerroTrace pertumorously within days 1-21, according to COHORT I : Patients are symptomically affected by the disease within days 1-21. Patients also have gastrectomy and are given indocyanine green peritumorally. Patients have gastrectomy and are given FerroTrace and ICG pertumorally during surgery.

Virologic and Immunologic Evaluation of Lymph Node, Tonsillar and Intestinal Biopsies, and Bronchoalveolar Lavage Fluid

Compared to HIV-infected patients, patients with Idiopathic CD4 lymphopenia, and healthy volunteers, HIV-uninfected with HIV can provide more insight into the pathogenesis of HIV infection and ICL. In addition, BAL's uninfected healthy volunteers will be enrolled in a tonsillar or intestinal biopsy, or bronchoscopy; this will enable testing of immunologic parameters in HIV-infected and uninfected BAL fluids and BAL fluids, which would allow for comparison of immunologic parameters in HIV-infected and uninfected BAL fluids or BAL fluids. To better understand the pathogenesis of their lymphopenia, ICL patients may perform tissue sampling to determine lymphocyte distribution and potential function in tissues. Sequential or simultaneous tissue sampling may be necessary, and longitudinal samples may also be obtained to determine stability in tissue compartments or the effects of potential immunomodulatory drugs.

Clinical, Laboratory, and Epidemiologic Characterization of Individuals and Families at High Risk of Blood and Lymph Node Malignancy

The study's scope and scope of familial neoplasm under scrutiny differed by the specific type of family neoplasm being studied. The comprehensive approach to eligible families includes defining affection status, diagnosis of disease, localization of genes, analysis of phenotype/genotype correlations, risk of the disease related to carrier status, and identification of other risk factors that influence penetrance including carrier status and identification of other risk factors that influence penetrance.

A Prospective Surveillance Program for Assessment and Treatment of Breast Cancer-Related Lymphedema After Axillary Lymph Node Dissection

After an axillary lymph node dissection, a new study is being conducted to determine how many women experience lymphedema. The investigators will also ask the patient to answer questions to see how much their quality of life is affected by lymphedema, and whether this report will help women avoid lymphedema earlier.

Detection of Sentinel Lymph Nodes in Patients With Endometrial Cancer Undergoing Robotic-Assisted Staging: Comparison of Isosulfan Blue and Indocyanine Green Dyes With Fluorescence Imaging

To predict nodal metastasis, it is necessary to determine the negative predictive value of pelvic sentinel lymph node in endometrial cancer. OUTLINE: Patients underwent sentinel lymph node biopsy with fluorescence imaging, isosulfan blue and sentinel lymph nodes biopsy, and complete pelvic lymph nodes dissection as indicated, as well as standard hysterectomy and salpingo-oophorectomy.

A Prospective Single-center Cohort Study "Preoperative Identification of Sentinel Lymph Nodes Using Contrast-enhanced CT Lymphography in Breast Cancer Patients"

We suspect that CT lymphography is a high-sensitivity and high-specificity technique for sentinel lymph nodes' mapping in breast cancer patients. We also believe that the positive predictive value and negative predictive value for detection of metastases in sentinel lymph nodes will be high enough for preoperative diagnosis of SLN metastases in breast cancer patients.
