My stimulant of choice is coffee. I started drinking it in first-year university, and never looked back. A tiny four-cup coffee maker became my reliable companion right through graduate school.
But since I stopped needing to drink a pot at a time, an entirely new category of products has appeared — the energy drink. Targeting students, athletes, and others seeking a mental or physical boost, energy drinks are now an enormous industry: From the first U.S. product sale in 1997, the market size was $4.8 billion by 2008, and continues to grow. (1)
My precious coffee effectively has a single therapeutic ingredient, caffeine. Its pharmacology is well documented, and the physiologic effects are understood. The safety data isn’t too shabby either: it’s probably not harmful and possibly is even beneficial. (I’m talking about oral consumption — no coffee enemas. Please.) In comparison, energy drinks are a bewildering category of products with an array of ingredients including caffeine, amino acids, vitamins, and other “natural” substances and assorted “nutraceuticals,” usually in a sugar-laden vehicle (though sugar-free versions exist). Given many products contain chemicals with pharmacologic effects, understanding the risks, signs of adverse events, and potential implications on drug therapy, are important.
So are energy drinks just candied caffeine delivery systems? Or are these syrupy supplements skirting drug regulations?
The Message
The ads are seductive. Who doesn’t want more energy? Who doesn’t want their mind and body “vitalized?” And don’t we have time-starved lifestyles? Initially envisioned for athletes, energy drinks are now marketed mainly towards teens and young adults, where uptake has been dramatic. Cross-promotion with extreme sporting events, and creating names like “Full Throttle,” “Rockstar,” and even “Cocaine” burnish the “extreme” image. The market is now segmented further with products targeted at women, vegetarians, diabetics, celiacs, and more. However you identify yourself, there’s probably an energy drink developed with you in mind. Read more »

Winterize Your Mind And Body
During the winter months, certain health issues may arise that women should have on their radar. From mental health issues like stress, depression and seasonal affective disorder (SAD), to physical concerns like skin care, the winter can certainly pack an extra punch.
Depression peaks during the holiday season, affecting more than 17 million Americans, according to the National Mental Health Association. On average, women are more vulnerable to stress-related illnesses like depression and anxiety than men. One study, conducted by Pacific Health Laboratories, revealed that 44 percent of American women report feeling sad through the holidays compared to 34 percent of American men.
“Depression of any kind is more common in females than males,” explains Greg Murray, M.D., lecturer and clinical psychologist at Swinburne University of Technology in Australia. “A pattern of elevated depression in the winter months is more marked in women than in men.”
There are a host of different reasons why women may be more susceptible to stress during the winter than men. Women tend to be the primary caretakers of the family and often take on the extra burden of the holidays with gift buying, entertaining, and coordinating visits with extended family. For working women, the added responsibilities can be difficult to balance, especially if they are already balancing a family, job, childcare and eldercare duties. Read more »

More Can Also Be Less: We Need A More Complete Public Discussion About Comparative Effectiveness Research
When the public turns its attention to medical effectiveness research, a discussion often follows about how this research might restrict access to new medical innovations. But this focus obscures the vital role that effectiveness research will play in evaluating current medical and surgical care.
I am now slogging through chemotherapy for stomach cancer, probably the result of high doses of radiation for Hodgkin lymphoma in the early 1970s, which was the standard treatment until long-term side effects (heart problems, additional cancers) emerged in the late 80s. So I am especially attuned to the need for research that tracks the short and long-term effectiveness — and dangers — of treatments.
Choosing a surgeon this September to remove my tumor shone a bright light for me on the need for research that evaluates current practices. Two of the three surgeons I consulted wanted to follow “standard treatment procedures” and leave a six-centimeter, cancer-free margin around my tumor. This would mean taking my whole stomach out, because of its anatomy and arterial supply.
The third surgeon began our consultation by stating that her aim would be to preserve as much of my stomach as possible because of the difference in quality of life between having even part of one’s stomach versus none. If at all possible, she wanted to spare me life without a stomach.
But what about the six-centimeter margin? “There isn’t really much evidence to support that standard,” she said. “This issue came up and was discussed at a national guidelines meeting earlier in the week. No one seemed to know where it came from. We have a gastric cancer registry at this hospital going back to the mid 1990s and we haven’t seen support for it there, either. A smaller margin is not associated with an increased risk of recurrence.” Read more »

Gene Goldwasser died last week. He was 88, and he was my friend.
I wrote previously about a series of conversations I conducted with Gene and Rabbi A.J. Wolf a few years ago. I met Gene one spring day after calling to invite him to sit in on a class I was teaching to a small group of medical students about social issues in healthcare.
I’d read about him in a book called “The $800 Million Pill,” by Merrill Goozner. In the book, Goozner writes the story of Gene’s two-decade hunt to isolate the hormone erythropoietin (EPO).
Part of the story relates how Gene tried to interest traditional big pharma companies in his discovery, only to be brushed aside. Instead, Gene wound up sharing his discovery with what became Amgen. The company went on to make a windfall from recombinant production of the hormone and licensing it as a drug for patients with anemia and kidney failure. Read more »

Rescuing Patients On Darvon Or Darvocet With Zero Tolerance For Pain
On November 19, 2010 the Food and Drug Administration (FDA) called for a halt in the use of the popular opioid pain relievers Darvocet and Darvon. These products contain the opioid propoxyphene, and it has been used to treat mild to moderate pain for over 50 years. However, concerns have long been raised about the effectiveness of this drug, and the risk of death (accidental and suicide). Darvon and Darvocet were banned in Britain in 2005, followed by the European Union in 2009. Over the past 30 years, the FDA has received numerous petitions to take these drugs off the U.S. market.
Research has shown that Darvon and Darvocet are no more effective for treating moderate pain than over the counter drugs like acetaminophen, aspirin or ibuprofen. Unfortunately, Darvon and Darvocet cause a lot more side effects such as dizziness, drowsiness, nausea and vomiting, hallucinations and constipation (all pretty typical of opioids used to treat pain). But, the side effects don’t stop there. The data is in, and it’s not a pretty picture. A recent study requested by the FDA showed that when used at the recommended doses, Darvon and Darvocet cause significant changes in the electrical activity of the heart, which can lead to a fatal irregularity in your heartbeat, even after only short-term use.
Among those advocating for the removal of these drugs from the market were pharmacists. The American Society of Health-System Pharmacists approved a policy in 2007 advocating for the withdrawal of Darvon and Darvocet from the U.S. market, and recently testified at the FDA Advisory Committee to this effect. As an often overlooked member of the medical team, pharmacists have a vital role to play in providing safe and effective treatments. We serve as the last line of defense against improper or unwise prescribing of drugs — especially those for pain. We are drug experts, and we can help patients and doctors switch from Darvon or Darvocet to safer and more effective treatments. Read more »
