Walnuts: A worthy addition to your daily diet?

What can you add to a wide variety of foods, from cereals to salads, that’s crunchy, filling, and flavorful — and good for your heart? The answer is nuts. While all varieties of nuts are chock full of important nutrients, walnuts may be especially good for protecting cardiovascular health, according to a recent study in the journal Circulation that supports earlier research in this realm.

What is the study?

The Walnuts and Healthy Aging study is a randomized controlled trial supported by a grant from the California Walnut Commission that tracked healthy older adults living in two communities. For the study, researchers recruited 708 adults ages 63 to 79 living in Loma Linda, California, or Barcelona, Spain, and split them into two groups. One group added about a quarter-cup to a half-cup of walnuts to their daily diet for two years, while the other group ate no walnuts.

After two years, average levels of harmful low-density lipoprotein (LDL) cholesterol were modestly lower in the walnut group. Of note: nearly a third of the participants were taking cholesterol-lowering statins, so the average cholesterol levels of both groups were already in a normal range. The researchers speculate that the cholesterol-lowering benefits from walnuts might be more pronounced in people with elevated cholesterol levels. There is no way to know from the current data if this is true.

“This recent trial confirms what earlier studies have found, namely, that that adding walnuts to your diet appears to improve your cholesterol levels,” says Dr. Deirdre Tobias, an obesity and nutritional epidemiologist at Harvard-affiliated Brigham and Women’s Hospital. The new trial also lasted much longer than past walnut studies. However, it’s not clear what foods were being replaced by the walnuts in the participants’ diets, which might affect the magnitude of benefits the researchers saw. For example, replacing unhealthful, ultra-processed snacks with walnuts would presumably have a greater benefit than a lateral move from healthy options to walnuts, Dr. Tobias explains.

Lower levels of harmful blood fats, no additional weight

The researchers also analyzed the concentration and size of the LDL particles. Smaller, more dense LDL particles are more likely to trigger atherosclerosis, the buildup of fatty plaque inside arteries that’s the hallmark of most cardiovascular disease that results in heart attacks or strokes.

The walnut eaters had lower levels of these smaller particles. They also had decreased levels of intermediate-density lipoproteins (IDL), which are also linked to a rise in cardiovascular-related risks. And even though a quarter-cup of chopped walnuts is about 190 calories (and a half-cup is about 380 calories), the walnut eaters did not pack on any extra pounds.

Earlier research has found that people who eat nuts regularly are less likely to have heart disease, and many studies have focused specifically on walnuts. In 2018, Dr. Tobias and colleagues published a meta-analysis and systematic review of studies that examined how eating walnuts affects a person’s blood lipids and other heart-related risks. The review included 26 controlled trials involving a total of more than 1,000 people. It found that walnut-enriched diets led to lower total cholesterol, LDL cholesterol, and triglycerides, the most common form of fat in the bloodstream.

What’s special about walnuts?

Although all nuts are good sources of healthy unsaturated fats, walnuts are especially rich in alpha-linolenic acid (ALA). This is a precursor to the omega-3 fatty acids EPA and DHA found in fatty fish that are known for their heart-protecting powers. Our bodies convert ALA to EPA and DHA, although the efficiency of this varies from person to person.

What’s more, walnuts are usually eaten raw. So they have greater antioxidant abilities than nuts that are usually eaten roasted. (Antioxidants help prevent or reduce the artery-damaging oxidation that contributes to heart disease).

Adding walnuts to your diet

It’s worth noting that the FDA allows a qualified health claim on some nuts (including walnuts). Foods made with them are permitted to include the following statement: “Eating a diet that includes one ounce of nuts daily can reduce your risk of heart disease.” An ounce of walnuts is about a handful, or one-quarter cup.

You can sprinkle walnuts onto oatmeal or other hot or cold cereals; stir them into pancakes, muffins, or other quick breads; or toss them with vegetables or into salads. If high cholesterol is a health concern for you, there are other foods that may help lower your LDL cholesterol and boost your heart health.

Acupuncture relieves prostatitis symptoms in study

df7957f6-88ac-4f97-8a2e-ed022cf8169e

Prostatitis gets little press, but it’s a common inflammatory condition that accounts for more than two million visits to doctors’ offices in the United States every year. Some cases are caused by bacteria that can be readily detected and treated with antibiotics. But more than 90% of the time, prostatitis symptoms (which can include painful urination and ejaculation, pelvic pain, and sexual dysfunction) have no obvious cause. This is called chronic nonbacterial prostatitis/chronic pelvic pain syndrome, or CP/CPPS. The treatments are varied. Doctors sometimes start with antibiotics if the condition was preceded by a urinary tract infection. They may also recommend anti-inflammatory painkillers, stress-reduction techniques, pelvic floor exercises, and sometimes drugs such as alpha blockers, which relax tight muscles in the prostate and bladder.

Another treatment that can work for some men is acupuncture. A 2018 review article of three published studies found that acupuncture has the potential to reduce CP/CPPS symptoms without the side effects associated with drug treatments.

Now, results from a newly published clinical trial show symptom reductions from acupuncture are long-lasting. Published in the prestigious journal Annals of Internal Medicine, the findings provide encouraging news for CP/CPPS sufferers.

Acupuncture involves inserting single-use needles into “acupoints” at various locations in the body, and then manipulating them manually or with heat or electrical stimulation. During the study, researchers at ten institutions in China assigned 440 men with prostatitis to receive 20 sessions (across eight weeks) of either real acupuncture, or a control sham procedure wherein the needles are inserted away from traditional acupoints.

The researchers were medical doctors, but the treatments were administered by certified acupuncturists with five years of undergraduate education and at least two years of clinical experience. Treatment benefits were assessed using the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), which assigns scores for pain, urinary function, and quality of life. The men were tracked for 24 weeks after the eight weeks of treatment sessions.

By week eight, just over 60% of men in the acupuncture group were reporting significant symptom improvements (with the exception of sexual dysfunction), compared to 37% of the sham-treated men. Importantly, these differences were little changed by week 32, indicating that the benefits of acupuncture were holding steady months after the treatments were initiated.

Precisely how acupuncture relieves prostatitis symptoms is unclear. The authors of the study point to several possibilities, including that stimulation at acupoints promotes the release of naturally occurring opioid-like chemicals (enkephalins, endorphins, and dynorphins) with pain-killing properties. Acupuncture may also have anti-inflammatory effects, and the experience of being treated can also have psychological benefits that result in symptom improvements, the authors speculated.

“The research on prostatitis CPPS has been very sparse and scarce, and often with disappointing results, so this article from practitioners who are also experts in acupuncture is very welcome,” said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, editor of the Harvard Health Publishing Annual Report on Prostate Diseases, and editor in chief of HarvardProstateKnowledge.org. “The possible causes of prostatitis are many and not fully understood. Furthermore, we do not fully understand how and why interventions that may occasionally aid in relieving troublesome symptoms work. If one is to avail themselves of acupuncture, my advice is to make certain that the acupuncturist that you select is well trained and qualified to perform this potentially important intervention.”

Low-carbohydrate and high-saturated fat diet: Heart healthy, or more to learn?

de5fba5f-287b-42a8-b6c0-5e4bb5427310

Various versions of low-carbohydrate diets have been popular for many years. The details of what is allowed and what is not vary quite a bit, and the amount of carbohydrates also differs. The common impression is a plate devoid of bread, pasta, and starchy vegetables, piled high with bacon, meat, eggs, and cheese, and maybe a small amount of vegetables and nuts. Due to the high saturated fat content in these diets, doctors and nutritionists worry about their potential adverse effect on cardiovascular disease.

Recently, a new study published in the American Journal of Clinical Nutrition has found that a low-carbohydrate, high-saturated fat diet might not be as bad as we feared. That sounds like good news, but is it that simple? Let’s take a look at what this randomized diet trial did and what the results really mean.

What did the study actually involve?

The 164 participants in this study were all considered overweight or obese, and had just finished a weight loss trial to lose 12% of their body weight. They were randomly assigned to one of three diets containing different proportions of carbohydrates and fat. Protein content was kept the same (at 20% calories) for everyone. They were not planning to lose any more weight.

The three diets were:

  • Low carbohydrates (20%), high fat (60%), saturated fat comprising 21% of calories: this resembles a typical low-carbohydrate diet and has much higher saturated fat than recommended.
  • Moderate carbohydrate (40%), moderate fat (40%), saturated fat comprising 14% of calories: this is not far from the typical American diet of 50% carbohydrates and 33% fat, and it is quite similar to a typical Mediterranean diet, which is slightly lower in carbohydrates and higher in fat than an American diet.
  • High carbohydrate (60%), low fat (20%), saturated fat comprising 7% of calories: this meets the recommendation of the Dietary Guidelines for Americans and is a typical high-carbohydrate diet, including a lot of grains, starchy vegetables, and fruits or juices.

The study participants received food prepared for them for 20 weeks. They had their blood measured for a number of risk factors of cardiovascular disease, and a lipoprotein insulin resistance (LPIR) score was calculated using a number of blood markers to reflect the risk for cardiovascular disease. (LPIR is a score that measures both insulin resistance and abnormal blood cholesterol all in one number, and it is used for research purposes.)

The researchers found that at the end of eating these diets for five months, the low-carbohydrate group, which also had consumed the highest amount of the presumably worrisome saturated fat, did not have the worst cardiovascular disease blood markers. The amount of good and bad cholesterol in the blood was not different from the other groups. In fact, the LPIR cardiovascular risk score and two other disease markers (Lp(a) and adiponectin) also were improved the most in this group. This seems to suggest that we can go ahead and not worry about the saturated fat that typically goes with a low-carbohydrate diet.

What were the participants actually eating?

Alas, those who were eating the low-carbohydrate diet were not piling up their plate with steak and bacon, and those eating the high-carbohydrate diets were not drinking unlimited soda. All three diets were high in plant foods and low in highly processed foods (it is easier to stick to a diet when all the food is prepared for you). Even the low-carbohydrate group was eating lentils, a good amount of vegetables, and quite a bit of nuts.

And although the diet was quite high in saturated fat, it was also high in the healthy poly- and monounsaturated fats as well. The meat was a combination of higher amounts of healthy (salmon) and a small amount of unhealthy (sausage) choices. In addition, fiber intake (at about 22 grams/day) was slightly higher than the average American intake (18 grams/day). Overall, except for saturated fat being higher than recommended, the diet as a whole was quite healthy.

What is the take-home message?

It seems that among a relatively young and healthy group of people (the average age of those who completed the study was 45 years old), higher amounts of saturated fat in the context of a healthy diet do not seem to adversely affect certain cardiovascular risk markers in the short term. How it would affect actual disease — such as heart attack, stroke, and diabetes — in the long run is unknown. However, there is ample evidence showing that a diet that consists of healthy foods and has moderate amounts of carbohydrate and fat can lower the risk of these diseases.

Preventing diseases is a long-term process; a healthy diet must not only be effective, but it should also be flexible enough for people to stick to in the long run. Therefore, a healthy diet with moderate amounts of healthy carbohydrates and ample healthy fats may be the easiest with which to achieve good health. Lower-carbohydrate diets might be promising, but further long-term testing is needed.

Tinnitus: Ringing or humming in your ears? Sound therapy is one option

550f6c24-195f-4dd2-b0aa-34c8268728c6

That recurring sound that you hear but nobody else does? It’s not all in your head. Well, not exactly.

You may be one of the estimated 50 million-plus people who suffer from tinnitus. The mysterious condition causes a sound in the head with no external source. For many it’s a high-pitched ringing, while for others it’s whistling, whooshing, buzzing, chirping, hissing, humming, roaring, or even shrieking.

The sound may seem to come from one ear or both, from inside the head, or from a distance. It may be constant or intermittent, steady or pulsating. One approach to managing this condition is different forms of sound therapy intended to help people tune out the internal soundtrack of tinnitus.

What causes tinnitus?

There are many possible causes of tinnitus. Long-term exposure to loud noises is often blamed. But other sources include middle ear problems like an infection, a tumor or cyst pinching nerves in the ear, or something as simple as earwax buildup. Tinnitus also can be a symptom of Meniere’s disease, a disorder of the balance mechanism in the inner ear.

Even old-fashioned aging can lead to tinnitus, which is common in people older than age 55. As people get older, the auditory nerve connecting the ear to the brain starts to fray, diminishing normal sounds.

“Neurons (nerve cells) in areas of the brain that process sound make up for this loss of input by increasing their sensitivity,” says Daniel Polley, director of the Lauer Tinnitus Research Center at Harvard-affiliated Massachusetts Eye and Ear. “The sensitivity knobs are turned up so high that neurons begin to respond to the activity of other nearby neurons. This creates the perception of a sound that does not exist in the physical environment. It’s a classic example of a feedback loop, similar to the squeal of a microphone when it is too close to a speaker.”

At times, everyone experiences the perception of a phantom sound. If it only lasts for a few seconds or minutes, it’s nothing to worry about. However, if it pulsates in sync with your heart rate, it’s definitely something to get checked out by a physician, says Polley. If it’s a relatively continuous sound, you should see an audiologist or otolaryngologist (ears, nose, throat specialist).

Can sound therapy help tune out tinnitus?

There is no cure for tinnitus, but it can become less noticeable over time. Still, there are ways to ease symptoms and help tune out the noise and minimize its impact. Treatments are a trial-and-error approach, as they work for some people but not others.

One often-suggested strategy is sound therapy. It uses external noise to alter your perception of or reaction to tinnitus. Research suggests sound therapy can effectively suppress tinnitus in some people. Two common types of sound therapy are masking and habituation.

  • Masking. This exposes a person to background noise, like white noise, nature sounds, or ambient sounds, to mask tinnitus noise or distract attention away from it. Listening to sound machines or music through headphones or other devices can offer temporary breaks from the perception of tinnitus. Household items like electric fans, radios, and TVs also can help. Many people with tinnitus also have some degree of hearing loss. Hearing aids can be used to mask tinnitus by turning up the volume on outside noises. This works especially well when hearing loss and tinnitus occur within the same frequency range, according to the American Tinnitus Association.
  • Habituation. Also known as tinnitus retraining therapy, this process trains your brain to become more accustomed to tinnitus. Here, you listen to noise similar to your tinnitus sound for long periods. Eventually your brain ignores the tone, along with the tinnitus sound. It’s similar to how you eventually don’t think about how glasses feel on your nose. The therapy is done with guidance from a specialist and the time frame varies per person, usually anywhere from 12 to 24 months.

Additional approaches may help with tinnitus

Depending on your diagnosis, your doctor also may recommend addressing issues that could contribute to your tinnitus.

  • Musculoskeletal factors. Jaw clenching, tooth grinding, prior injury, or muscle tension in the neck can sometimes make tinnitus more noticeable. If tight muscles are part of the problem, massage therapy may help relieve it.
  • Underlying health conditions. You may be able to reduce the impact of tinnitus by treating conditions like depression, anxiety, and insomnia.
  • Negative thinking. Adopting cognitive behavioral therapy and hypnosis to redirect negative thoughts and emotions linked to tinnitus may also help ease symptoms.
  • Medication. Tinnitus can be a side effect of many medications, especially when taken at higher doses, like aspirin and other nonsteroidal anti-inflammatory drugs and certain antidepressants. The problem often goes away when the drug is reduced or discontinued.

A new targeted treatment for early-stage breast cancer?

In the US, breast cancer is the most commonly diagnosed cancer in women, and the second leading cause of cancer-related deaths. Each year, an estimated 270,000 women — and a far smaller number of men — are diagnosed with it. When caught in early stages, it’s usually highly treatable.

A promising new form of targeted treatment may expand options available to some women with early-stage breast cancer linked to specific genetic glitches. (Early-stage cancers have not spread to distant organs or tissues in the body.)

The BRCA gene: What does it do?

You may have heard the term BRCA (BReast CAncer) genes, which refers to BRCA1 and BRCA2genes. Normally, BRCA genes help repair damage to our DNA (genetic code) that occurs regularly in cells throughout the human body.

Inherited BRCA mutations are abnormal changes in these genes that are passed on from a parent to a child. When a person has a BRCA mutation, their body cannot repair routine DNA damage to cells as easily. This accumulating damage to cells may help pave a path leading to cancer. Having a BRCA1 or BRCA2 mutation — or both — puts a person at higher risk for cancer of the breast, ovaries, prostate, or pancreas; or for melanoma. A person’s risk for breast cancer can also be affected by other gene mutations and other factors.

Overall, just 3% to 5% of all women with breast cancer have mutations in BRCAgenes. However, BRCA mutations occur more often in certain groups of people, such as those with triple negative breast cancer (TNBC), Ashkenazi Jewish ancestry, a strong family history of breast and/or ovarian cancer, and younger women with breast cancer.

Inherited BRCA mutations and breast cancer types

Certain types of breast cancer are commonly found in women with BRCA gene mutations.

  • Estrogen receptor-positive, HER2-negative cancer: Women with a BRCA2 mutation usually develop ER+/HER2- breast cancer — that is, cancer cells that are fueled by the hormone estrogen but not by a protein known as HER2 (human epidermal growth factor 2).
  • Triple negative breast cancer: Women with a BRCA1 mutation tend to develop triple negative breast cancer (ER-/PR-/HER2-) — that is, cancer cells that aren’t fueled by the hormones estrogen and progesterone, or by HER2.

Knowing what encourages different types of breast cancer to grow helps scientists develop new treatments, and helps doctors choose available treatments to slow or stop tumor growth. Often this involves a combination of treatments.

A new medicine aimed at early-stage BRCA-related breast cancers

The OlympiA trial enrolled women with early-stage breast cancer and inherited BRCA1/BRCA2 mutations. All were at high risk for breast cancer recurrence despite standard treatments.

Study participants had received standard therapies for breast cancer:

  • surgery (a mastectomy or lumpectomy)
  • chemotherapy (given either before or after surgery)
  • possibly radiation
  • possibly hormone-blocking treatment known as endocrine therapy.

They were randomly assigned to take pills twice a day containing olaparib or a placebo (sugar pills) for one year.

Olaparib belongs to a class of medicines called PARP inhibitors. PARP (poly adenosine diphosphate-ribose polymerase) is an enzyme that normally helps repair DNA damage. Blocking this enzyme in BRCA-mutated cancer cells causes the cells to die from increased DNA damage.

Results from this study were published in the New England Journal of Medicine. Women who received olaparib were less likely to have breast cancer recur or metastasize (spread to distant organs or tissues) than women taking placebo. Follow-up at an average of two and a half years showed that slightly more than 85% of women who had received olaparib were alive and did not have a cancer recurrence, or a new second cancer, compared with 77% of women treated with placebo.

Further, the researchers estimated that at three years:

  • The likelihood that cancer would not spread to distant organs or tissues was nearly 88% with olaparib, compared to 80% with placebo.
  • The likelihood of survival was 92% for the olaparib-treated group and 88% for the placebo group.

The side effects of olaparib include low white cell count, low red cell count, and tiredness. The chances of developing these were low.

The bottom line

Olaparib is already approved by the FDA to treat BRCA-related cancers of the ovaries, pancreas, or prostate, and metastatic breast cancer. FDA approval for early-stage breast cancer that is BRCA-related is expected soon based on this study. These findings suggest taking olaparib for a year after completing standard treatment could be a good option for women who have early-stage breast cancer and an inherited BRCA gene mutation who are at high risk for cancer recurrence and, possibly, its spread.

Skin in the game: Two common skin problems and solutions for men

895ae13d-3d7c-473c-99b8-6add3931098a

When I was on the junior varsity basketball team in high school, I wasn't surprised when I developed a case of itchy, flaky athlete's foot. After all, I was an "athlete," so I assumed it was a sign of dedication and hard work.

I was shocked when my mother told me the truth: it was due to poor foot hygiene, not my dribbling skills.

Fast-forward almost four decades, and I’m much more diligent about skin care. Still, some skin issues plague me at times, like they do many men. Here is a look at two common problems and solutions.

Dry skin

Symptoms of dry skin include scaly patches (with or without redness), itching, and overall dryness. You can get dry skin year-round — from the heavy heat of summer to the bitter cold of winter. Sun exposure damages skin, leaving it thinner and less likely to hold in moisture over time. Also, aging skin produces less of the natural oils that keep skin lubricated.

Treatment. The first line of defense is a moisturizer that softens and smooths skin with water and lipids (fats). Some moisturizers attract water to the skin and seal it in. Others prevent moisture loss by coating skin with a thick, impermeable layer.

  • Petroleum jelly. This waxy, greasy substance stops water loss without clogging pores. It can be used by itself but is also an ingredient in many moisturizers and ointments. Because petroleum jelly doesn’t contain water, it’s best used while the skin is still damp after bathing to seal in moisture.
  • Mineral oil. Mineral oil has the same effect but without a greasy feeling. It also should be used while skin is damp.
  • Moisturizing lotions and creams. These products contain both water and oils. They’re less greasy and more cosmetically appealing than petroleum jelly or oils. Look for moisturizers with at least one of the following ingredients: glycerin, urea, pyroglutamic acid, sorbitol, lactic acid, lactate salts, or alpha hydroxy acids.

Prevention. Try a few changes to help prevent dry skin:

  • Add moisture to the air with a humidifier or a pan of water set atop the radiator.
  • In the shower or bath, use lukewarm water (hot water can dry the skin by stripping it of natural oils).
  • Choose nondrying soaps with no abrasives or irritants. Super-fatted soaps or cleansing bars are less drying than regular, liquid, or antibacterial soaps.
  • To retain the water your skin absorbs while showering or bathing, apply jelly, oil, or moisturizer immediately afterward.

Athlete’s foot

Athlete’s foot is caused by dermatophytes, a group of fungi on the surface of the skin. Tell-tale signs include intense itching; cracked, blistered, or peeling areas of skin, especially between the toes; and redness and scaling on the soles. Dermatophytes thrive in warm, moist environments like pools, showers, and locker rooms where people walk with bare feet. The warm, moist environment of sweaty socks and shoes encourages them to grow.

Treatment. First, try an over-the-counter antifungal ointment, cream, or powder, such as clotrimazole (Lotrimin AF, Mycelex, generic), terbinafine (Lamisil AT, Silka,), or miconazole (Lotrimin AF spray, Micatin). It can take weeks for an infection to improve, and recurrences are common. If symptoms don't improve after several weeks, consult a doctor, who may prescribe antifungal pills.

Prevention. Keeping feet clean and dry is the best way to ward off athlete’s foot. Also, do the following:

  • Wash your feet well every day, and wear a clean pair of socks after your bath or shower.
  • Take time to dry your feet thoroughly (including each toe and especially the web space between the toes) after you bathe, shower, or swim.
  • Wear flip-flops or sandals around public pools and in gym locker rooms and showers.
  • Wear moisture-wicking socks that absorb sweat.
  • Don’t wear the same shoes two days in a row. Give shoes a 24-hour break between wearings to air out and dry.

What it takes to achieve world-changing scientific breakthroughs

fd30f478-b920-4e18-b0d1-ad48129e30a2

In science, advances are a daily occurrence, but true breakthroughs are rare. What does it take to achieve world-changing scientific breakthroughs? Some are the result of a lucky accident, combined with curiosity: scientists traveling down one road suddenly find reason to veer onto another road, one they never planned to travel — a road that may well lead nowhere.

Other major breakthroughs stem from scientists pursuing a very specific dream. One day, usually early in their career, they get an idea that they can’t stop thinking about. It’s crazy, they say to themselves, but is it really impossible? They talk to respected colleagues who often remind them of all the reasons their idea might not work, and how damaging this could be for their career. It’s a sobering message, yet the idea won’t die. So, they scramble to find financial support and seek out colleagues willing to risk traveling that road with them — a road that may well lead nowhere. But sometimes the road leads to major breakthroughs like penicillin and mRNA vaccines.

Breakthroughs due to lucky accidents and curiosity

One day in 1928, Dr. Alexander Fleming at St. Mary’s Hospital in London was growing bacteria in a laboratory dish. Fleming was not pursuing a scientific dream. He was a microbiologist, just doing his job.

Then he noticed something odd: overnight, another kind of microbe, a fungus, had traveled through the air, landed on the laboratory dish, and started to grow and spread on the dish where the bacteria were growing. Fleming soon noticed that the growing fungus seemed to be killing the bacteria. He surmised that it was making some substance that killed the bacteria. Because the name of the fungus was Penicillium rubens, he called the substance the fungus was making “penicillin.”

When Fleming published a paper about his discovery, few were interested. It took another 10 years before other scientists tried to generate large amounts of penicillin to see if it might be able to cure bacterial infections and save lives. We all know how that worked out.

Fleming’s scientific breakthrough, like some others, occurred not because Fleming had a brilliant idea and exclaimed “Eureka!” Instead, it occurred because he noticed something and said, “That’s odd,” and then tried to figure it out.

Breakthroughs due to persistence and resilience in pursuit of a dream

The story of mRNA vaccines, like the Pfizer/BioNTech and Moderna vaccines for COVID-19, is very different from the story of penicillin. For 30 years, a small group of scientists believed that mRNA vaccines would have great advantages over traditional vaccines — if only several obstacles could be overcome. Many of these scientists gave up as they encountered those obstacles, but a few persisted and, ultimately, succeeded. (I described what mRNA vaccines are, how they work, and how obstacles were overcome in a previous blog post.)

One scientist, Dr. Katalin Karikó, joined the faculty of the University of Pennsylvania in the early 1990s with the dream of creating an mRNA vaccine. She applied for grants to support her work, but was repeatedly rejected: the reviewers stated that it was so unlikely that she or anyone could overcome the obstacles that supporting her research would be a wasted investment. Her university only agreed to continue supporting her work if she accepted a demotion and a pay cut. She accepted both, and doggedly pursued her dream.

One major obstacle to mRNA vaccines particularly fascinated her: the violent reaction of the immune system when it encounters mRNA from a virus. Ten years of dogged work helped Karikó and her colleague Drew Weissman figure out how to make a small change in mRNA that prevented that violent immune response — a major step in making all mRNA vaccines possible. Without this, the world wouldn’t have mRNA COVID vaccines today.

Two other scientists who created the Pfizer/BioNTech COVID vaccine, Uğur Şahin and Őzlem Turëci, are Turkish immigrants to Germany who met, fell in love with the idea of creating an mRNA vaccine, and then fell in love with each other. According to The Wall Street Journal, one day in 2002 they took a break for lunch, got married, and then returned in the afternoon to their laboratory to finish an experiment — just one more among many conducted over 30 years. Each experiment was one more possible step toward their ultimate dream until finally, in 2020, they achieved that dream: their mRNA vaccine for COVID-19 proved to be very safe and effective.

Holding hard to their dreams

Whichever path scientists who achieve lifesaving breakthroughs travel, they often endure disinterest, like Fleming, or repeated skepticism, ridicule, and rejection, like Karikó, Weissman, Şahin, and Turëci. Only through sheer persistence did these scientists bring their dreams to life. They have been rewarded with fame and wealth and something even more valuable: the knowledge that because of their work hundreds of millions of people around the world never got sick, and millions never died before their time.

Of course, a relentless obsession with an improbable dream fails to pay off for many scientists. Their ideas, while quite brilliant, in the end are proved wrong: nature doesn’t turn out to operate the way they predicted. In the end, their beautiful theory is murdered by a brutal gang of facts.

Still other scientific dreamers ultimately prove to have been on the right track all along and would have achieved their dream — if only they had done the experiment a little differently, if only they had persisted a little longer, or if only the support for their work had not run out. As a result, neither they nor the rest of us benefitted from what would have been — until other scientists rediscovered their work years later.

Ultimately, scientific breakthroughs are possible only if a society is willing to invest in dreamers, recognizing that not all investments will lead to major breakthroughs. However, the investments that do lead to breakthroughs bring an economic return that is far greater than the investment — as well as preventing suffering and death and changing the world.

Navigating a chronic illness during the holidays

As a doctor, I am constantly advising my patients to prioritize their own mental and physical health. Get adequate sleep. Eat healthy. Learn how to say no so you don’t collapse from exhaustion. Love and care for yourself like you do others.

I talk the talk but don’t always walk the walk — even though I know, both intellectually and physically, that self-care is critical to my well-being. When I am run down, my MS symptoms cry out for attention: left leg weakness and numbness, subtle vertigo, a distinct buzzing in my brain like a relentless mosquito that won’t go away no matter how many times I twitch and shake my head. I have become frighteningly good at ignoring these symptoms, boxing them up and pushing them away. Often, I can muscle through; other times it just hurts.

Recently, a friend challenged me to think about my relationship with my illness, to describe MS as a character in my story. This was a useful exercise. I conjured up an image of a stern teacher. She is frighteningly blunt and lets me know, loud and clear, when I disappoint her. She can be mean and scary, and I don’t really like her. But I must admit she is usually right. Still, I often defiantly dismiss her, even when part of me knows this is not in my best interest.

This holiday season, I wanted to do better. I needed to do better. So, as Thanksgiving approached, as I prepared to host 16 family members, many for multiple days, I paused to ask myself, What does MS have to teach me about self-care? I don’t like having this disease, but I do. I can’t change my reality, so I might as well benefit from the lessons MS is forcing on me. I believe they are relevant to all of us, whether we live with chronic illness or not, so I’ll share them here.

The first steps: Listen and observe

When my MS symptoms flare, it’s a message that I am tired, overextended, and stressed. I need to rest. I don’t always listen right away, but eventually I am forced to, and when I listen, I feel better. All of us can benefit from slowing down and tuning in to our physical selves. What sensations are you experiencing in your body, and what does this tell you about your underlying feelings and state of mind? Yes, we should heed our thoughts, but tuning in to our bodies takes us deeper, to feelings that might be hidden, secrets we might not want to acknowledge, a physical truth. If you don’t have a chronic illness, the messages might be more subtle — a vague tightness in your chest, a quick catch in your breath, a barely noticeable tremor in your hands — but they exist, and they signal stress.

The science is clear: the body’s stress response — though potentially lifesaving in a true emergency, when “fight or flight” is essential to survival — can be toxic in our everyday lives. Stress triggers our sympathetic nervous system to kick into overdrive in response to a perceived threat, releasing hormones such as cortisol and inflammatory molecules that, when produced in excess, fuel disease. Conversely, we know that pausing to take notice and interrupting this negative cycle of stress is beneficial. It can be as simple as breathing deeply and counting to 10. Our bodies know what’s up and let us know when we need to take care of ourselves. We must pay attention.

You are not responsible for everyone and everything

The holidays, essentially from mid-November through the end of the year, are a stress test we create for ourselves. The land mines are everywhere: more food, more drinking, more family dynamics, more unfamiliar (or overly familiar) surroundings. Personally, with my overinflated sense of responsibility, I experience a kind of dizzying performance anxiety every holiday season. I believe it is my job to make sure everyone present has a positive experience. For better or worse, I am someone who notices and feels the personal and interpersonal dynamics in a room. I sense and absorb even the most subtle discomfort, frustration, anger, shame, and insecurity, alongside the more upbeat emotions. Importantly, I also I feel the need to step in and make things better, to prop everyone up. It’s exhausting. But MS reminds me of how absurd, and even egotistical, this is. In truth, I can’t possibly care for everyone. Neither can you.

It helps to check our automatic thoughts. More than once on Thanksgiving Day, as the busy kitchen buzzed with activity and conversation, I intentionally stepped back and watched, reminding myself that I didn’t have to hold the whole thing up. Even though I inevitably slipped back into hyper-responsibility mode, these moments of self-awareness impacted my behavior and the dynamic in the room.

It’s okay to say what you need

To take full responsibility for my own well-being, I need to speak honestly and act with integrity. This means asking for what I need, clearly and without apology. Historically, I have been terrible at this in my personal life, burying my own needs in the name of taking care of everyone else’s, even rejecting clear offers of help. “I’m good, I’ve got it,” I might say, while simultaneously feeling bitter and resentful for having to do it all myself. This lack of clarity isn’t fair to anyone. MS reminds me that I need to do better.

This year, when my guests asked me what they could bring, I took them at their word and made specific requests instead of assuring everyone that I had it covered. When my mother started banging around in the kitchen at 7 a.m. with her endearing but chaotic energy, asking for this and that pot and kitchen utensil so she could start cooking, I told her I needed to sit down and have a cup of coffee first. She would need to wait or find things herself. She was okay with that. Family dynamics can be entrenched and hard to change, but clear communication can set new ways of being into motion, one baby step at a time.

I still have a lot to learn, but I am making stuttering progress, learning to listen to my body and honor my needs while also caring for those I love, or at least trying. Undeniably, I experienced some post-Thanksgiving fatigue, exacerbated by my daughter’s early-morning hockey game the next day, requiring a 4:30 a.m. departure. I felt it in my body — the familiar leg weakness, vertigo, and brain cobwebs — and, completely uncharacteristically, I took a nap.

Harvard Health Ad Watch: An upbeat ad for a psoriasis treatment

Psoriasis is a chronic disease in which skin cells rapidly divide, causing the skin to develop rough, red, scaly patches. Plaque psoriasis is the most common form: affected skin has sharply defined, inflamed patches (plaques) with silvery or white scales, often near an elbow or on the shins and trunk.

The cause of psoriasis isn’t known, but there are a number of treatment options. Possibly you’ve seen a glossy, happy ad for one of these treatments, a drug called Skyrizi. It’s been in heavy rotation and in 2020, hit number four on a top 10 list for ad spending by a drug company.

Splashing in blue water

A woman in a bathing suit sprints down a dock and jumps into the water with several friends. There’s lots of smiling and splashing. A voiceover says “I have moderate to severe plaque psoriasis. Now, there’s Skyrizi. Three out of four people achieved 90% clearer skin at four months after just two doses.”

Then, the voiceover moves to warning mode: “Skyrizi may increase your risk of infections and lower your ability to fight them. Before treatment your doctor should check you for infections and tuberculosis. Tell your doctor if you have an infection or symptoms such as fever, sweats, chills, muscle aches, or cough, or if you plan to or recently received a vaccine.”

As these warnings are delivered, we’re treated to uplifting pop music — “nothing is everything,” a woman sings — while attractive young people flail about in the water.

“Ask your doctor about Skyrizi,” a voice instructs. Did I mention a plane is skywriting the drug’s logo? I guess it’s putting the “sky” in Skyrizi.

What is Skyrizi?

Skyrizi (risankizumab) is an injectable medication that counteracts interleukin-23, a chemical messenger closely involved in the development of psoriasis. The standard dosing is two injections to start, followed a month later by two injections once a month, and then two injections once every three months.

Did you catch that “injectable” part? This is not a pill. If you missed that point while watching the commercial, it’s not your fault. The word “injection” appears once, written in faint letters at the very end of the commercial.

By the way, the FDA has only approved this drug for moderate to severe — not mild — plaque psoriasis. The studies earning approval enrolled people with psoriasis on at least 10% of their skin and two separate measures of severity.

What the ad gets right

  • The ad states that 75% of people with moderate to severe psoriasis experienced 90% clearance of their rash within four months after only two doses of Skyrizi. This reflects the findings of research studies (such as this one) that led to the drug’s approval.
  • The recommendations regarding screening for infections (including tuberculosis) and telling your doctor if you’ve gotten a recent vaccine are appropriate and should be standard practice. By lowering the ability to fight infection, this drug can make current infections worse. It may reduce the benefit of certain vaccines, or increase the risk of infection when a person gets a certain type of vaccine called a live-attenuated vaccine.

And the theme song? People with visible psoriasis often cover up their skin due to embarrassment or stigma. The rash isn’t a contagious infection or a reflection of poor health, but other people may react as if it is. So, an effective treatment could potentially allow some to forego covering up and show more skin: it means “everything” to someone suffering with psoriasis to cover “nothing.” Thus, a theme song is born.

What else do you need to know?

A few things about this ad may be confusing or incomplete, including:

  • Currently, each dose of Skyrizi is actually two injections. So, a more accurate way to summarize its effectiveness would be to say that improvement occurred within four months after four injections (rather than “just two doses”).
  • Like most newer injectable medications, this one is quite expensive: a year's supply could cost nearly $70,000. The drug maker offers a patient assistance program for people with low income or limited health insurance, but not everyone qualifies. Health insurance plans generally require justification from your doctor for medications like Skyrizi, and your insurer may decide not to cover it. Even if covered, this prior approval process can delay starting the medication, which may still be expensive due to copays and/or deductibles.
  • There is no mention of the many other options to treat psoriasis, some of which are far less costly. These include medications that do not have to be injected (such as oral methotrexate or apremilast), and UV light therapy (phototherapy). And there are other injectable medications. So, ask your doctor about the best options for you.

The bottom line

Some people appreciate the information provided by medication ads. Others favor a ban on such advertising, as is the case in most other countries. And recently, two advocacy groups asked the FDA not to allow drug ads to play music when the risks of drug side effects are presented, arguing that it distracts consumers from focusing on this important information.

Since these ads probably are not going away anytime soon, keep in mind that they may spin information in a positive light and leave out other important information altogether. So, be skeptical and ask questions. Get your medication information from your doctor or another unbiased, authoritative source, not a company selling a product.

Regardless of how you feel about medical advertising, it’s hard to hate the Skyrizi theme song. Feel free to sing along.
