Primary Care Corner with Geoffrey Modest MD: Metformin, CKD, and death
By: Dr. Geoffrey Modest A rather unusual quick-and-dirty study was just published looking at the relationship between metformin use and mortality, as well as lactic acidosis, in those with severe chronic kidney disease, CKD. This study was based on a window of time until 2009, when metformin was used in Taiwan without restriction in those with renal disease (See doi.org/10.1016/S2213-8587(15)00123-0). The […]

Primary Care Corner with Geoffrey Modest MD: PPIs associated with MIs???
By: Dr. Geoffrey Modest There was a recent article published online and hitting the press regarding a possible association between the use of proton-pump inhibitors (PPIs) and subsequent MIs (see DOI:10.1371/journal.pone.0124653).

Primary Care Corner with Geoffrey Modest MD: Tight diabetes control and cardiovasc disease– followup of the VA study
By: Dr. Geoffrey Modest The Veterans Affairs Diabetes Trial (VADT) was one of the triumvirate published around 2009, along with the ACCORD and ADVANCE trials, which looked at intensive glycemic control and cardiovascular outcomes.

Primary Care Corner with Geoffrey Modest MD: DPP-4 inhibitors and cardiovascular outcomes
By: Dr. Geoffrey Modest New Engl J of Med just had a large study on the cardiovascular effects of sitagliptin (see DOI: 10.1056/NEJMoa1501352). Background: sitigliptin is a DPP-4 inhibitor (dipeptidyl peptidase 4 inhibitor), which functions by decreasing the degradation of incretins (and thereby increasing glucose-mediated endogenous insulin secretion and suppressing glucagon levels). But there were concerning […]

Primary Care Corner with Geoffrey Modest MD: IMPROVE-IT trial ezetimibe
By: Dr. Geoffrey Modest So, at long last, the IMPROVE-IT trial has been published: the one comparing simvastatin plus ezetimibe vs simvastatin alone in high-risk patients (this was the study that came out as the block-buster, high-profile study at the Am Heart Assn meetings last November –7 months ago!!!, but was notably not published simultaneously, for remarkably opaque reasons….. see DOI: […]
