Today NPR ran a story about fierce competition and cooperation among mouse sperm cells trying to fertilize an ovum. Apparently spermatozoa from the same male will often clump together, wiggling their flagella in a collective swim that accelerates the group faster towards an egg. In the race to be the first sperm to fertilize an egg this team approach (with sperm of a feather flocking together) may confer an evolutionary advantage. Solo-swimmers move more leisurely. The research and cool video presented on NPR were of sperm from the promiscuous deer mouse. Such murine sperm “behavior” may not be as evolutionarily needed in (usually) less promiscuous humans. Yet the idea of sperm cooperation, fitness, and competition in a microscopic steeplechase is fascinating. Read more »

Since mainstream media is feeding parents a constant stream of health information that is often inaccurate and poorly vetted (just ask Gary Schwitzer), I thought it would be helpful to create a new series at Better Health: Mythbusters for Moms. Now, I know that moms aren’t the only ones who will benefit from “straight talk” from healthcare professionals, but the alliteration was simply irresistible.
Our first guest of the series is Dr. Rahul Parikh. Rahul is a board-certified pediatrician who works at Kaiser Permanente’s Walnut Creek Medical Center in California. Prior to becoming a pediatrician, Rahul completed a degree in molecular biology at UC Berkeley, and his medical degree at Tufts in Boston.
Online, Rahul is perhaps best known for his columns, featured at Salon.com. There he takes a critical look at media misinformation about health and science, and has spoken out against misleading content promoted by Oprah Winfrey and the Huffington Post.
You may listen to an audiocast of our conversation here (or read a short transcript below):

This past weekend’s international science communication conference, ScienceOnline2010, also saw the first, final hardback copies of Rebecca Skloot’s long-awaited book make it into the hands of the science and journalism consuming public. Moreover, an excerpt of The Immortal Life of Henrietta Lacks has just appeared in the new issue of Oprah Winfrey’s O Magazine. And already, those online science communicators who left the conference with Skloot’s book are registering their praise via this Twitter feed that was so active it was a trending topic at the science aggregator, SciencePond.
The story of the rural, Virginia woman who descended from slaves and developed cervical cancer in the early 1950s is notable most obviously for her tumors giving rise to HeLa, the first immortalized human cell line continuously maintained in culture. I have noted previously my enthusiasm for this story as both a long-time admirer of Skloot’s writing and the fact that HeLa played a central role in my PhD thesis work and first papers from my independent laboratory.

California debuted new rules that specify patients in health maintenance organizations (HMO) see a doctor within 10 days of asking for an appointment. Calls must be return within a half-hour, and health professionals must be available 24/7. Urgent care must be seen in 48 hours.
Richard Frankenstein, FACP, former president of the California Medical Association, told the Los Angeles Times that this places pressure on the HMOs to have a big enough network to deliver what they promise. Critics contend this will force doctors to rush patient care even more, or be especially damaging to rural areas already facing a shortage. Read more »

It’s the fastest growing “specialty” service in medicine: hospitalist medicine. These are the doctors who limit their practice to the care and management of patients admitted to the hospital. It has been wildly popular because it adds a shift-like work schedule to medical care for physicians while supposedly preserving their personal life. It also moves patients through the hospital faster, shortening length of stays. As one of our more esteemed hospitalist bloggers likes to boast: it’s a “WIN-WIN!”
At least until the hospitalist service gets too busy. Read more »
