Enhancing Pharmacovigilance from the US Experience: Current Practices and Future Opportunities.

This review is intended to present perspectives from the US experience in enhancing pharmacovigilance on current practices and future opportunities. Best practices concepts could be applied worldwide through the presentation of how three pillars of pharmacovigilance: (1) medical and scientific excellence, (2) operational and compliance excellence, and (3) knowledge sharing and experts development in the field could serve as a framework for the establishment of an efficient and successful global pharmacovigilance system.

Prevalence and cost of HIV-associated weight loss in a managed care population.

Objective: To estimate the prevalence of HIV-associated weight loss among HIV patients in a US managed care population, and compare demographic and clinical characteristics of HIV patients with and without evidence of HIV-associated weight loss.

Research Design And Methods: A retrospective observational study was conducted using a large, geographically diverse US managed care population to identify commercial enrollees with HIV/AIDS from 1/1/2005-7/31/2007, based on a combination of HIV/AIDS diagnosis codes or antiretroviral treatment. HIV-associated weight loss status was defined according to an algorithm combining evidence for weight loss-associated conditions, anorexia symptoms, and various treatments for weight loss or wasting.

Inflammation and its relationship to insulin resistance, type 2 diabetes mellitus, and endothelial dysfunction.

In the past decade, clinical, laboratory, and epidemiological research have coalesced to give rise to a new paradigm for understanding type 2 diabetes mellitus (DM). In this review, we present data that DM has an inflammatory etiology and that inflammation plays a role in diabetic complications, especially cardiovascular disease. This new paradigm offers insight into the relationship between DM and obesity.

Role of a critical visceral adipose tissue threshold (CVATT) in metabolic syndrome: implications for controlling dietary carbohydrates: a review.

There are likely many scenarios and pathways that can lead to metabolic syndrome. This paper reviews mechanisms by which the accumulation of visceral adipose tissue (VAT) may contribute to the metabolic syndrome, and explores the paradigm of a critical VAT threshold (CVATT). Exceeding the CVATT may result in a number of metabolic disturbances such as insulin resistance to glucose uptake by cells.
