Increased risk of venous thromboembolism in patients with granulomatosis with polyangiitis: A population-based study.

We assessed the risk and time trends of venous thromboembolism (VTE) including pulmonary embolism (PE) and deep venous thrombosis (DVT) in new granulomatosis with polyangiitis (GPA) cases compared to the general population. Using a population-level database from the entire province of British Columbia, Canada, we conducted a matched cohort study of all patients with incident GPA with up to ten age-, sex-, and entry time-matched individuals randomly selected from the general population. We compared incidence rates of VTE, PE, and DVT between the two groups, and calculated hazard ratios (HR), adjusting for relevant confounders.

Premature Spinal Bone Loss in Women Living with HIV is Associated with Shorter Leukocyte Telomere Length.

With advances in combination antiretroviral therapy (cART), people living with HIV are now surviving to experience aging. Evidence suggests that individuals living with HIV are at greater risk for low bone mineral density (BMD), osteoporosis, and fractures. Better understanding of the pathophysiology of bone health in women living with HIV (WLWH) is important for treatment strategies.

Risk of Myocardial Infarction and Stroke in Patients With Granulomatosis With Polyangiitis (Wegener's): A Population-Based Study.

Objective: To assess the relative risk of myocardial infarction (MI) and ischemic stroke in patients with newly diagnosed granulomatosis with polyangiitis (Wegener's) (GPA) compared with that in controls from the general population.

Methods: Using a population-based database from the province of British Columbia, Canada, we conducted a matched cohort study in which each patient with incident GPA was matched for age, sex, and entry time with up to 10 individuals from the general population. Patients in the GPA cohort were required to have received at least 1 prescription for oral glucocorticoids, methotrexate, cyclophosphamide, leflunomide, azathioprine, cyclosporine, mycophenolate mofetil, or rituximab within 1 month before or 6 months after the index date.

Endocrine abnormalities in HIV-infected women are associated with peak viral load - the Children and Women: AntiRetrovirals and Markers of Aging (CARMA) Cohort.

Objectives: To investigate the prevalence of endocrine disturbances in a group of HIV-positive (HIV+) women and to identify factors affecting presence of these disorders. To examine specifically whether cellular ageing, as measured by leukocyte telomere length (LTL), is correlated with the presence of endocrine disturbance.

Design: A cross-sectional retrospective substudy of an ongoing prospective cohort study.

Phosphorylation of GATA-6 is required for vascular smooth muscle cell differentiation after mTORC1 inhibition.

Vascular smooth muscle cells (VSMCs) undergo transcriptionally regulated reversible differentiation in growing and injured blood vessels. This dedifferentiation also contributes to VSMC hyperplasia after vascular injury, including that caused by angioplasty and stenting. Stents provide mechanical support and can contain and release rapamycin, an inhibitor of the mechanistic target of rapamycin complex 1 (mTORC1).
