End-Of-Life Planning Makes It Easier To Say Goodbye
Saying goodbye as the end of life approaches can be difficult, even for those with a gift for words. In a moving account in a recent issue of The New Yorker, writer Joyce Carol Oates describes the last week of her 49-year marriage, as her husband was dying from complications of pneumonia. Like A Year of Magical Thinking, Joan Didion’s poignant memoir of her husband’s sudden death and its aftermath, Oates’ essay highlights the need for each of us to think about death and dying — and discuss them with loved ones — long before they become a likelihood.
In our work with individuals and families facing death, we have seen too many people miss the opportunity to say goodbye because they avoid what feels like a scary or taboo topic: What do I want to happen when I die? Beginning this discussion early, preferably while you are in good health, can help pave the way for a “good death.” In our new book, Saying Goodbye: How Families Can Find Renewal Through Loss, we offer a guide to help individuals facing a terminal illness and their families navigate the realities of death and dying. Planning ahead is essential. Here are some suggestions for doing that:
Choose your team. Identify support people and specialists (legal, medical, financial, religious) you can count on to advocate for you and help you make decisions. Designate these people to act for you by signing advance medical directives. Read more »

Good news for parents, teachers, pediatricians, and others engaged in the ongoing battle against lice: The Food and Drug Administration (FDA) just approved a new treatment for head lice in children age four and older. Called Natroba, it’s a liquid that is rubbed into the hair and allowed to sit for 10 minutes before being rinsed off. Natroba is a useful addition to the anti-lice arsenal, since some head lice have become resistant to permethrin and pyrethrins, the active ingredients in over-the-counter anti-lice products such as Nix and Rid.
Head lice are tiny insects that go by the big name Pediculus humanus capitis. They thrive in the warm tangle of human hair, feeding off blood in the scalp and breeding with abandon. A female lays eggs called nits that she attaches to strands of hair. Nits hatch after about eight days, become adults in another week or so, feed for awhile, then begin to make more lice.

What To Do
First off, here’s what not to do: Don’t shave your or your child’s head, or coat it with petroleum jelly or mayonnaise or anything else designed to “suffocate” the parasite. You’ll probably end up with greasy, smelly, lice-infested hair.
Current guidelines from the American Academy of Pediatrics call for the use of an over-the-counter product containing permethrin or pyrethrins as a first salvo against head lice. Shampoos and rinses made with these substances are generally effective. Most treatments for head lice need to be used twice, seven to 10 days apart, along with combing wet hair with a fine-toothed nit comb. Some lice are resistant to pyrethrin and permethrin. Stronger prescription drugs, such as malathion and lindane, also work but aren’t as safe for humans. That’s where Natroba comes in. Read more »

There’s hematology news, times two (at least):
1. Progress in developing synthetic red blood cells
A University of North Carolina-Chapel Hill research group has created hydrogel particles that mimic the size, shape and flexibility of red blood cells (RBCs). The researchers used PRINT® (Particle Replication in Non-wetting Templates) technology to generate the fake RBCs, which are said to have a relatively long half-life. The findings were reported on-line yesterday in the Proceedings of the National Academy of Sciences (PNAS) (abstract available, subscription required for full text). According to a PR-ish but interesting post on Futurity, a website put forth by a consortium of major research universities, tests of the particles’ ability to perform functions such as transporting oxygen or carrying therapeutic drugs have not yet been conducted.
Developing competent, artificial RBCs is a hematologist’s holy grail of sorts, because with that you might alleviate anemia without the risks of transfusion.
2. Progress in using human stem cells to generate lots of platelets
In an exciting paper published today in Cell Research, investigators stimulated human embryonic stem cells to become platelet-producing cells, called megakaryocytes. According to the article (open-text at Nature PG), the platelets were produced in abundance, appeared typical and clotted appropriately in response to stimuli in vitro. The researchers injected them into mice, used high-speed video microscopy for imaging, and demonstrated that the stem cell-derived human platelets contributed to clot formation in mice, in vivo (i.e., they seem to work).

After shoveling the heavy, 18-inch layer of snow that fell overnight on my sidewalk and driveway, my back hurt, my left shoulder ached, and I was tired. Was my body warning me I was having a heart attack, or were these just the aftermath of a morning spent toiling with a shovel? Now that I’m of an AARP age, it’s a question I shouldn’t ignore.
Snow shoveling is a known trigger for heart attacks. Emergency rooms in the snowbelt gear up for extra cases when enough of the white stuff has fallen to force folks out of their homes armed with shovels or snow blowers.
What’s the connection? Many people who shovel snow rarely exercise. Picking up a shovel and moving hundreds of pounds of snow, particularly after doing nothing physical for several months, can put a big strain on the heart. Pushing a heavy snowblower can do the same thing. Cold weather is another contributor because it can boost blood pressure, interrupt blood flow to part of the heart, and make blood more likely to form clots.
When a clot forms inside a coronary artery (a vessel that nourishes the heart), it can completely block blood flow to part of the heart. Cut off from their supply of life-sustaining oxygen and nutrients, heart muscle cells begin to shut down, and then die. This is what doctors call a myocardial infarction or acute coronary syndrome. The rest of us call it a heart attack.
The so-called classic signs of a heart attack are a squeezing pain in the chest, shortness of breath, pain that radiates up to the left shoulder and down the left arm, or a cold sweat. Other signs that are equally common include jaw pain, lower back pain, unexplained fatigue or nausea, and anxiety. Read more »

When reports arrived that accused gunman Jared Lee Loughner had opened fire in Tucson, Arizona on January 7, journalistic first responders linked the incident to the fierceness of political rhetoric in the United States. Upon reflection, some of the discussion has turned to questions about mental illness, guns, and violence.
And plenty of reflection is required, because the connections are not at all simple. To get a sense of just how complicated they are, we invite you to read the lead article in this month’s Harvard Mental Health Letter entitled, “Mental Illness and Violence.” Strangely (for us) it was prepared for publication a month before the tragedy in Tucson. In light of the shooting, we are making the article available to non-subscribers.
I am not surprised at the outrage expressed in the news or at the impulse to blame. A quick scan of the news, however, shows there is not much agreement about whom to blame. In addition to the alleged perpetrator, one can find explicit and implicit criticisms of politicians for playing to our baser instincts; of media figures, various men and women of zeal, for their disingenuous or manipulative partisanship; of the various community bystanders (police, teachers, doctors, family members, neighbors, friends), whom we imagine could have intervened to prevent tragedy.
The political debate flowing from this incident will continue, as will the endless cycle of blame and defensiveness. But I caution all of us — and especially mental health professionals — not to make clinical judgments about Mr. Loughner. Very few people will or should have access to the kind of information that would allow such judgments. From a public health perspective, however, we should make careful judgments about policies that could reduce risk. Read more »
