It is becoming increasingly apparent that men and women have significant differences in their physiology, and subsequent manifestation of disease phenotypes. At the same time, scientists increasingly view physiology as it changes, rather than as static points in time. Those trends come together in a new paper in JAMA Cardiology, which looks at the most ubiquitous of cardiovascular diseases: high blood pressure.

According to the CDC, approximately 26 million Americans smoke tobacco daily. In comparison, 14.6 million smoke marijuana every day. In the headlong green rush for dollars -- it's, after all, a $7 billion market in the U.S. -- no one has been able to answer the question of whether all that pot smoking has any ill effects.
With vanishingly few exceptions, we do not understand the underlying causes of dementia. A new study adds evidence to the hypothesis that unintended side-effects of anticholinergics may be involved.
Poor sleep is almost certainly linked to migraines, despite the findings of a new study suggesting otherwise. Though I'm merely a sample size of n = 1, Continuous Positive Airway Pressure therapy has dramatically decreased the number of morning migraines I experience. As it turns out, the study design has some flaws.
For an operation -- specifically, total knee replacement -- how do we identify when the "Goldilocks moment" arrives? That is, not too early, when there's little benefit to the patient bearing unnecessary risk. Or not too late, when the delay has further limited physical activity, increasing long-term disability and recovery. A new study searches for some answers about how to find the "just right" time.
KCAL9, the CBS affiliate in Los Angeles, invited conspiracy theorist Zen Honeycutt -- an anti-GMO, anti-vaccine, conspiracy-mongering snake oil saleswoman and founder of Moms Across America -- to discuss children's health.
Pop Quiz: What's the average body temperature? Answer: 98.6° F (but you probably knew that). But a new study suggests that our new normal is a bit lower: 98.2° F. Why would that be? And does it matter?
The idea was promoted with much fanfare. And to be honest, it made a lot of sense. For the 5% of patients who are chronically ill, the superusers that use up to 20% of our healthcare resources provide them with the necessary additional support. In the tradeoff, their health will improve, and our costs will decline. With similar coverage, the New England Journal of Medicine says that there was no improvement in outcomes. But there's more to it. Let's take a look.
When last I looked, J&J had $325 million in judgments against them in lawsuits over talc baby powder and its presumed role as a cause of ovarian cancer in several women. Even the International Agency for Research on Cancer, the people that believe hot beverages are probably carcinogenic, "… has since concluded there is only 'possible' evidence that perineal use of talc-based body powder may be carcinogenic." A new study in JAMA looks at four cohort studies with long-term information on talc use and subsequent self-reported ovarian cancer. It seems that possible may be too strong; they found no linkage.
Infectious diseases, such as influenza and tuberculosis, kill millions every year. But an infectious disease can kill in another way: by causing cancer. The good news is that many of these infections are preventable or treatable.
If you were about to undergo a significant operation – OK, even if you were just going “under the knife” for a minor one – what would be your biggest concern? We're figuring simply surviving the operation is high on the list, if not #1. Taking this thought experiment a step further, would it matter that the time period to ensure your survival was one month, 90 days or a year?
Norovirus has hit the U.S. hard and early this winter. It's not enough to simply stay away from people who are sick. There are innocent-looking, healthy evil-doers out there whose bodies are secret virus factories, and they are just as "happy" to give it to you as the guy with his head in the toilet.
