The level of microbial translocation from the intestine is increased in HIV-1 infection. Proinflammatory cytokine production by peripheral antigen-presenting cells in response to translocated microbes or microbial products may contribute to systemic immune activation, a hallmark of HIV-1 infection. We investigated the cytokine responses of peripheral blood(More)
BACKGROUND Systemic inflammation is a characteristic of both HIV-1 infection and aging ("inflammaging"). Intestinal epithelial barrier damage (IEBD) and microbial translocation (MT) contribute to HIV-associated inflammation, but their impact on inflammaging remains unclear. METHODS Plasma biomarkers for IEBD (iFABP), MT (LPS, sCD14), T-cell activation(More)
Optical coherence tomography (OCT) has established itself as the dominant imaging modality in the management of glaucoma and retinal diseases, providing high-resolution visualization of ocular microstructures and objective quantification of tissue thickness and change. This article reviews the history of OCT imaging with a specific focus on glaucoma. We(More)
BACKGROUND Abdominal contour deformities after massive weight loss are highly variable, ranging from a mild upper protuberance to multiple rolls. Correction of these deformities is challenging and may require advanced surgical techniques. Evaluating the incidence of patients presenting with various abdominal deformities and the factors influencing these(More)
Since the introduction of commercial optical coherence tomography (OCT) systems, the ophthalmic imaging modality has rapidly expanded and it has since changed the paradigm of visualization of the retina and revolutionized the management and diagnosis of neuro-retinal diseases, including glaucoma. OCT remains a dynamic and evolving imaging modality, growing(More)
BACKGROUND Hepatobiliary and pancreatic (HPB) operations have a high incidence of post-operative nosocomial infections. The aim of the present study was to determine whether hospitalization up to 1 year before HPB surgery is associated with an increased risk of post-operative infection, surgical-site infection (SSI) and infection resistant to surgical(More)
