“This job is killing me” is not a statement of jest. It is a desperate plea of outright sincerity.
Stress, anxiety, depression — all have been associated with an increased risk of cardiovascular disease and mortality. But can interventions to help people cope with stress positively affect longevity and decrease risk of dying? The results of a new study in the Archives of Internal Medicine would imply the answer is an encouraging “yes.”
Constructively dealing with stress is easier said than done, but it would seem logical that if we can reduce our psychological and social stressors we might live longer and delay the inevitable wear and tear on our vessels. This study proved that one such intervention, cognitive behavioral therapy (CBT) for patients who suffered a first heart attack, lowered the risk of fatal and nonfatal recurrent cardiovascular disease events by 41 percent over eight years. Nonfatal heart attacks were almost cut in half. Excitement may be dampened by the fact that all-cause mortality did not statistically differ between the intervention and control groups, but did trend towards an improvement in the eight years of follow up.
Definitely less suffering. Maybe less deaths.
The authors state that psychosocial stressors have been shown to account for an astounding 30 percent of the attributable risk of having a heart attack. Chronic stressors include low socioeconomic status, low social support, marital problems, and work distress. Emotional factors also correlated with cardiovascular disease include major depression, hostility, anger, and anxiety. Read more »

The FDA [has] issued an alert about a possible link between breast implants — saline or silicone — and a rare form of lymphoma called anaplastic large cell lymphoma (ALCL). These lymphoma cases are exceedingly rare, but the association appears to be significant.
The FDA identified a total of approximately 60 ALCL cases in association with implants, worldwide. Of these, 34 were identified by review of published medical literature from 1997 to May, 2010; the others were reported by implant manufacturers and other sources. The agency estimates the number of women worldwide with breast implants is between five and 10 million. These numbers translate to between six and 12 ALCL cases in the breast, per million women with breast implants, assessed over 13 years or so.
In women who don’t have implants, ALCL is an infrequent tumor, affecting approximately one in 500,000 women is the U.S. per year. This form of lymphoma — a malignancy of lymphocytes, a kind of white blood cell — can arise almost anywhere in the body. But ALCL cases arising in the breast are unusual. The FDA reports that roughly three in 100,000,000 women are diagnosed with ALCL in the breast per year in the U.S.
These are very small numbers. Still, the finding of ALCL tumors by the implant capsules is highly suggestive. Almost all of the implant-associated ALCL cases were T-cell type, whereas most breast lymphomas are of B-cell type. The lymphomas arose in women with both silicone and saline-type implants, and in women with implants placed for purposes or augmentation and for reconstruction after mastectomy. Read more »

This picture shows the view from my office window in Boston: Dull, dreary, and depressing — at least on overcast days like today. Lack of light is one of the reasons that people feel mentally foggy.
One of the bloggers I follow, Rachel Zimmerman of WBUR’s CommonHealth blog, recently wrote that she’s been drinking three times as much coffee as usual. In addition to imbibing more caffeine, I’ve been trying to boost my spirits and alertness with mid-day runs to the snack machine (not the best strategy, in case you’re wondering).
At this time of year, many people aren’t just foggy and sad — they’ve got SAD, or seasonal affective disorder. About half a million Americans — women more often than men — are diagnosed with seasonal affective disorder each year. Many others experience at least some of the symptoms, which include loss of pleasure and energy, inability to concentrate, feelings of worthlessness, and an uncontrollable urge to eat sugar and high-carbohydrate foods (in my case, chocolate chip cookies).
Bright white light therapy remains a mainstay of treatment for seasonal affective disorder. That’s because the light acts on cells in the retina, the tissue located at the back of the eye that sends visual information to the brain. The hypothalamus, which helps control the sleep-wake cycle, is one part of the brain that receives this information. During the winter months, when people tend to stay indoors more, days are shorter, and the weather becomes overcast, our exposure to natural light diminishes. That disrupts the sleep-wake cycle, as well as other circadian rhythms. The result can be symptoms of seasonal affective disorder. Read more »

The journey to a healthy pregnancy and delivery begins with the selection of a healthcare provider, and the challenge is to find the right one. This is the person who will be in charge of your pregnancy up until the time of the delivery, so it certainly is not a casual date. For the next 280 days your life and the life of your unborn child will be in this person’s hands. A background check is therefore in order.
One of the best ways to find the right healthcare provider is by word-of-mouth referral from neighbors, friends, or family members however please don’t stop there. Labor and delivery nurses are also a great source of referral because they have seen physicians and midwives under their most vulnerable and challenging moments.
Don’t feel intimidated about checking a provider’s credentials — this is public information. You can find out whether the provider’s medical license is current or expired. You’ll also be able to obtain information on whether the provider has ever been disciplined by the board for medical malpractice or unprofessional behavior or misconduct. Healthcare providers are not exempt from problems with alcoholism, drug addiction, professional incompetence, and unprofessional or unethical behaviors. Although less than five percent of healthcare providers have egregious problems, you want to make certain that your provider is not one of them. Read more »

Information circulating about the dangers of plastic containers has created fear and confusion. Are plastic containers toxic? Do harmful chemicals leach out into its contents? Do we need to discard all plastic containers?
Recently, I interacted in a live health chat on MedHelp about the safety of plastics. Scientist, Joe Schwarcz, Ph.D., Director of McGill University’s Office for Science and Society, talked about “The Real Truth About Plastics: What You Should And Shouldn’t Worry About.”
While Dr. Schwarcz states that some plastics like those made by Tupperware and Rubbermaid are safe to use, there are other plastics made of Bisphenol A (BPA) that may cause some concern, however he did not become alarmed.
There is extensive information on the safety of plastics, and reading some of it can easily cause panic and confusion, but the smartest step health consumers can do for themselves is to remain calm and don’t become alarmed. Gather the facts and determine what’s best for you.
The Facts About Bisphenol A (BPA)
Bisphenol A (BPA) is used to manufacture polycarbonate plastics. This type of plastic is used to make some types of beverage containers, compact disks, plastic dinnerware, impact-resistant safety equipment, automobile parts, and toys. BPA epoxy resins are used in the protective linings of food cans, in dental sealants, and in other products.
General exposure to BPA at low levels comes from eating food or drinking water stored in containers that have BPA. Small children may be exposed by hand-to-mouth and direct oral (mouth) contact with materials containing BPA. Dental treatment with BPA-containing sealants also results in short-term exposure. In addition, workers who manufacture products that contain BPA can be exposed.
How Does BPA Get Into The Body?
BPA can leach into food from the epoxy resin lining of cans and from consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles. Additional traces of BPA can leach out of these products when they are heated at high temperatures. Read more »
