An antidote on the horizon? An update on the progress toward achieving reversibility for the new oral anticoagulants

By Gabriel Schneider, MD

Peer Reviewed

The new oral anticoagulants (NOACs) are an appealing alternative to the burdensome vitamin K antagonists such as warfarin. These novel agents include direct thrombin inhibitors such as dabigatran (which inhibits thrombin) and factor Xa inhibitors such as rivaroxaban and apixaban (which prevent thrombin generation). Compared to warfarin, NOACs have fewer food and drug interactions, as well as a more predictable pharmacodynamic profile that serves to obviate the need for the frequent outpatient monitoring in most patients. In addition…

Mammograms in the News, Yet Again

Mammograms are far from strangers to the paparazzi. It was only recently that a television news reporter from a prominent broadcasting company reluctantly agreed to have a mammogram performed on live television to promote breast cancer screening and help “save lives” . That same study diagnosed her with breast cancer, which was followed by the impressive statement from her physicians: “that mammogram just saved your life”. But over the last day or two several major newspapers are presenting…

His vitals are significant for a blood pressure of 220/110 and a heart rate of 170. On physical exam he appears to be profusely sweating, and his pupils are markedly dilated. Troponin I is…

There are certain laws in the universe that are just not meant to be broken.  One is gravity.  Another one is relativity.  The third, don’t give contrast to people with bad kidneys.   Perhaps the last one is not so much a law as something we seem to be terrified of doing.  While recently on service, I had a patient with unexplained right lower quadrant pain.  The…

How Much Do We Know About HDL Cholesterol?

By Gregory Katz, MD

Peer Reviewed

As levels of HDL cholesterol increase, rates of heart disease go down. It’s this fact that has given HDL its reputation as the “good cholesterol,” serving a crucial role in reverse cholesterol transport. According to our models, HDL ferries cholesterol away from our arteries – where its buildup leads to heart disease and stroke – and back towards our liver, safely out of harm’s way. The epidemiology backs this up: people with higher levels of HDL tend to…

You rush to the bathroom, tripping over the clothes that speckle your apartment. Your heart pounds inside your chest and your hands shake ever so subtly.

Is it Time to Skip the Gym?

By Robert Mocharla, MD

Peer Reviewed

No. Sorry. Despite such reasonable excuses as – “I forgot my iPod”, “It’s pouring rain”, or “Game of Thrones is on” — an exhaustive literature search will not reveal a shred of evidence that you or most of your patients should skip daily exercise. However, a subset of your patients should indeed be skipping workouts regularly. The group referred to consists of endurance athletes (e.g. cyclists, swimmers, long-distance runners, competitive athletes). While this may not describe the majority of…
