BACKGROUND: Recent calls for reform in healthcare training emphasize using competency-based curricula and information technology-empowered learning. Continuing Medical Education programs are essential in maintaining physician accreditation. Haitian physicians have expressed a lack access to these activities. The Haiti Medical Education Project works in alliance with Haitian medical leadership, faculty and students to support the Country's medical education system. We present the creation, delivery and evaluation of a competency-based continuing medical education curriculum for physicians in rural Haiti...

PURPOSE: Through genome-wide expression profile analysis, hypoxia-inducible protein 2 (HIG2) has previously been identified as an oncoprotein involved in development/progression of renal cell carcinoma (RCC). We subsequently identified a highly immunogenic HLA-A*0201/0206-restricted epitope peptide (HIG2-9-4) corresponding to a part of HIG2 and applied it as a therapeutic vaccine. We conducted a phase I clinical trial using the HIG2-9-4 peptide for patients with advanced RCC. MATERIALS AND METHODS: Nine patients having HLA-A*0201 or HLA-A*0206 with metastatic or unresectable RCC after failure of the cytokine and/or tyrosine kinase inhibitor therapies were enrolled in this study...

Connective tissue diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis, and scleroderma, have a strong predilection for women and are associated with a marked increase in the prevalence of hypertension. The mechanisms leading to the increased risk of hypertension in these patients remain unclear; however, they are likely related to immune mediated changes in cardiovascular and renal function. Over the past several years, we have elucidated a number of factors that contribute to the development of hypertension during SLE using a widely established experimental model of SLE, the female NZBWF1 mouse...

OBJECTIVE: Afferent renal nerves exhibit a dual function. They influence intrarenal immunological processes by release of neurokinins like CGRP and control central sympathetic outflow via afferent electrical activity. The former seems to be important in renal inflammation whereas the sympathetic modulation by afferent electrical activity is not fully understood in cardiovascular disease and hypertension. Hence, we hypothesized that augmented effects of CGRP in renal inflammation occur with increased afferent renal nerve activity...

Here we describe the case of a HIV-infected patient with polycystic kidney disease and end stage renal diseases not transplantable due to the persistence of a CD4 count <200 notwithstanding a good virological response to highly active antiretroviral therapy and suggest that such limitation to kidney transplantation in such as cases might be bypassed.

Laparoscopic donor nephrectomy (LDN) can be performed via either transperitoneal or retroperitoneal approach. Very few studies have been carried out till now, comparing immunologic and inflammatory responses in donors after these two approaches. This is a prospective observational study. Selection of approach was decided by the operating surgeon. All patients underwent peripheral venous blood sampling preoperatively and 24 h postoperatively for the measurement of C-reactive protein (CRP), interleukein-6 (IL-6), total leukocyte count (TLC), blood urea nitrogen (BUN), and serum creatinine (SCr)...

AIMS: Sorafenib, which has been used extensively for the treatment of renal cell cancer and advanced hepatocellular carcinoma (HCC), has also been shown to have antifibrotic effects in liver fibrosis. However, the effects of sorafenib on renal fibrosis are unknown. Therefore, we investigated whether sorafenib inhibited renal fibrosis in a mouse model of unilateral ureteral obstruction (UUO) and further explored the potential mechanism. METHODS: Mice underwent UUO followed by vehicle or sorafenib treatment...

BACKGROUND: Fc-gamma receptors (FCGRs) are expressed on immune cells, bind to antibodies, and trigger antibody-induced cell-mediated anti-tumor responses when tumor-reactive antibodies are present. The affinity of the FCGR/antibody interaction is variable and dependent upon FCGR polymorphisms. Prior studies of cancer patients treated with immunotherapy indicate that FCGR polymorphisms can influence antitumor response for certain immunotherapies that act via therapeutically administered mAbs or via endogenous tumor-reactive antibodies induced from tumor antigen vaccines...

BACKGROUND & AIMS: Cryoglobulins (circulating immune complexes of polyclonal IgG, monoclonal IgM, and rheumatoid factor) are detected in the circulation of 40%-60% of patients with chronic hepatitis C virus infection and cryoglobulinemic vasculitis (CV) is observed in approximately 10% of patients. We aimed to assess the clinical and immune effects of direct-acting antiviral (DAA) treatment. METHODS: We performed a prospective study of 64 patients with HCV infection with circulating cryoglobulins receiving direct-acting anti-viral therapy at a single center in Barcelona, Spain from January 2014 through April 2016...

Haemolytic uraemic syndrome (HUS) is defined by the simultaneous occurrence of nonimmune haemolytic anaemia, thrombocytopenia and acute renal failure. This leads to the pathological lesion termed thrombotic microangiopathy, which mainly affects the kidney, as well as other organs. HUS is associated with endothelial cell injury and platelet activation, although the underlying cause may differ. Most cases of HUS are associated with gastrointestinal infection with Shiga toxin-producing enterohaemorrhagic Escherichia coli (EHEC) strains...

Cancer immunotherapy is at dawn of the Renaissance after the Medieval Dark Ages. Recent advances of understanding tumor immunology and molecular drug development are leading us to the epoch of cancer immunotherapy. Some types of immunotherapy have shown to provide survival benefit for patients with solid tumors such as malignant melanoma, renal cell carcinoma, or non-small cell lung cancer. Several studies have suggested that immune checkpoint inhibition might be effective in some patients with gastrointestinal cancers...

Immune checkpoint inhibitors targeting the inhibitory cross talk between tumor and immune cells have been approved for therapy in renal cell carcinoma (RCC). In contrast to clear cell RCC, little is known on PD-1/PD-L1 expression patterns in rarer RCC subtypes. The aim of this study was to evaluate the prevalence, distribution and prognostic impact of PD-1 and PD-L1 expression in chromophobe (ch)RCC. Patients who underwent renal surgery due to chRCC were retrospectively evaluated. Tumor specimen was analyzed for PD-1 and PD-L1 expression by immunohistochemistry...
