Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

Long-term risk of rosiglitazone on cardiovascular events: a systematic review and meta-analysis.
Abstract Rosiglitazone has been proposed as a treatment strategy for type 2 diabetes mellitus (T2DM), could provide robust glucose-lowering capability with risk of cardiovascular events. We thus did a systematic review and meta-analysis of controlled trials to assess the effect of this treatment on glycaemic control, cardiovascular events in patients with T2DM. We systematically search PubMed, Embase and Cochrane Central Register of Controlled Trials comparing rosiglitazone to other anti-diabetic treatments. These studies included randomized controlled trials (RCTs), cohort studies, and case-control studies that h...

Cardiovascular benefits and safety of non-insulin medications used in the treatment of type 2 diabetes mellitus.
Authors: Yandrapalli S, Jolly G, Horblitt A, Sanaani A, Aronow WS Abstract Diabetes mellitus is a growing in exponential proportions. If the current growth trend continues, it may result in every third adult in the United States having diabetes mellitus by 2050, and every 10(th) adult worldwide. Type 2 diabetes mellitus (T2DM) confers a 2- to 3-fold increased risk of cardiovascular (CV) events compared with non-diabetic patients, and CV mortality is responsible for around 80% mortality in this population. Patients with T2DM can have other features of insulin resistance-metabolic syndrome like hypertension, lipid ab...

Expensive New Diabetes Drugs Add Nothing But Cost And Complications
This is the fourth in an ongoing series of blogs exposing the rampant misuse of the medications so aggressively promoted by greedy drug companies. I am very lucky in having the perfect partner in this truth-vs-power effort to contradict Pharma propaganda with evidence based fact. Dick Bijl is President of the International Society of Drug Bulletins (ISDB), an impressive association of 53 national drug bulletins from all around the world, each of which publishes the best available data on the pluses and minuses of different medications. Drug bulletins help patients and doctors see through the misleading misinformation ge...
