Active surveillance for prostate cancer has its tradeoffs. Available to men with low- and intermediate-risk prostate cancer, the process entails monitoring a man’s tumor with periodic biopsies and prostate-specific antigen (PSA) tests, and treating only when — or if — the disease shows signs of progression.

Active surveillance allows men to avoid (at least for a while) the side effects of invasive therapies such as surgery or radiation, but men often feel anxious wondering about the state of their cancer as they spend more time untreated. Is there a middle path between not treating the cancer at all and aggressive therapies that might have lasting side effects? Emerging evidence suggests the answer might be yes.

During a newly-published phase 2 clinical trial, researchers evaluated whether a drug called enzalutamide might delay cancer progression among men on active surveillance. Enzalutamide interferes with testosterone, a hormone that drives prostate tumors to grow and spread. Unlike other therapies that block synthesis of the hormone, enzalutamide prevents testosterone from interacting with its cellular receptor.

A total of 227 men were enrolled in the study. The investigators randomized half of them to a year of daily enzalutamide treatment plus active surveillance, and the other half to active surveillance only. After approximately two years of follow-up, the investigators compared findings from the two groups.

The results showed benefits from enzalutamide treatment. Specifically, tumor biopsies revealed evidence of cancer progression in 32 of the treated men, compared to 42 men who did not get the drug. The odds of finding no cancer in at least some biopsy samples were 3.5 times higher in the enzalutamide-treated men. And it took six months longer for PSA levels to rise (suggesting the cancer is growing) in the treated men, compared to men who stayed on active surveillance only.

Enzalutamide was generally well tolerated. The most common side effects were fatigue and breast enlargement, both of which are reversible when men go off treatment.

In an accompanying editorial, Susan Halabi, a statistician who specializes in prostate cancer at Duke University, described the data as encouraging. But Halabi also sounded a cautionary note. Importantly, differences between the two groups were evident only during the first year of follow-up. By the end of the second year, signs of progression in the treated and untreated groups “tended to be very similar,” she wrote, suggesting that enzalutamide is beneficial only for as long as men stay on the drug. Longer studies lasting a decade or more, Halabi added, may be necessary to determine if early enzalutamide therapy changes the course of the disease, such that the need for more invasive treatments among some men can be delayed or prevented.

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, said the study points to a new way of approaching active surveillance, either with enzalutamide or perhaps other drugs. “An option that further decreases the likelihood that men on active surveillance will need radiation or surgery is important to consider,” he says. “This was a pilot study, and now we need longer-term research.”

Let’s face it: inflammation has a bad reputation. Much of it is well-deserved. After all, long-term inflammation contributes to chronic illnesses and deaths. If you just relied on headlines for health information, you might think that stamping out inflammation would eliminate cardiovascular disease, cancer, dementia, and perhaps aging itself. Unfortunately, that’s not true.

Still, our understanding of how chronic inflammation can impair health has expanded dramatically in recent years. And with this understanding come three common questions: Could I have inflammation without knowing it? How can I find out if I do? Are there tests for inflammation? Indeed, there are.

Testing for inflammation

A number of well-established tests to detect inflammation are commonly used in medical care. But it’s important to note these tests can’t distinguish between acute inflammation, which might develop with a cold, pneumonia, or an injury, and the more damaging chronic inflammation that may accompany diabetes, obesity, or an autoimmune disease, among other conditions. Understanding the difference between acute and chronic inflammation is important.

These are four of the most common tests for inflammation:

• Erythrocyte sedimentation rate (sed rate or ESR). This test measures how fast red blood cells settle to the bottom of a vertical tube of blood. When inflammation is present the red blood cells fall faster, as higher amounts of proteins in the blood make those cells clump together. While ranges vary by lab, a normal result is typically 20 mm/hr or less, while a value over 100 mm/hr is quite high.
• C-reactive protein (CRP). This protein made in the liver tends to rise when inflammation is present. A normal value is less than 3 mg/L. A value over 3 mg/L is often used to identify an increased risk of cardiovascular disease, but bodywide inflammation can make CRP rise to 100 mg/L or more.
• Ferritin. This is a blood protein that reflects the amount of iron stored in the body. It’s most often ordered to evaluate whether an anemic person is iron-deficient, in which case ferritin levels are low. Or, if there is too much iron in the body, ferritin levels may be high. But ferritin levels also rise when inflammation is present. Normal results vary by lab and tend to be a bit higher in men, but a typical normal range is 20 to 200 mcg/L.
• Fibrinogen. While this protein is most commonly measured to evaluate the status of the blood clotting system, its levels tend to rise when inflammation is present. A normal fibrinogen level is 200 to 400 mg/dL.

Are tests for inflammation useful?

In certain situations, tests to measure inflammation can be quite helpful.

• Diagnosing an inflammatory condition. One example of this is a rare condition called giant cell arteritis, in which the ESR is nearly always elevated. If symptoms such as new, severe headache and jaw pain suggest that a person may have this disease, an elevated ESR can increase the suspicion that the disease is present, while a normal ESR argues against this diagnosis.
• Monitoring an inflammatory condition. When someone has rheumatoid arthritis, for example, ESR or CRP (or both tests) help determine how active the disease is and how well treatment is working.

None of these tests is perfect. Sometimes false negative results occur when inflammation actually is present. False positive results may occur when abnormal test results suggest inflammation even when none is present.

Should you be routinely tested for inflammation?

Currently, tests of inflammation are not a part of routine medical care for all adults, and expert guidelines do not recommend them.

CRP testing to assess cardiac risk is encouraged to help decide whether preventive treatment is appropriate for some people (such as those with a risk of a heart attack that is intermediate — that is, neither high nor low). However, evidence suggests that CRP testing adds relatively little to assessment using standard risk factors, such as a history of hypertension, diabetes, smoking, high cholesterol, and positive family history of heart disease.

So far, only one group I know of recommends routine testing for inflammation for all without a specific reason: companies selling inflammation tests directly to consumers.

Inflammation may be silent — so why not test?

It’s true that chronic inflammation may not cause specific symptoms. But looking for evidence of inflammation through a blood test without any sense of why it might be there is much less helpful than having routine healthcare that screens for common causes of silent inflammation, including

• excess weight
• diabetes
• cardiovascular disease (including heart attacks and stroke)
• hepatitis C and other chronic infections
• autoimmune disease.

Standard medical evaluation for most of these conditions does not require testing for inflammation. And your medical team can recommend the right treatments if you do have one of these conditions.

The bottom line

Testing for inflammation has its place in medical evaluation and in monitoring certain health conditions, such as rheumatoid arthritis. But it’s not clearly helpful as a routine test for everyone. A better approach is to adopt healthy habits and get routine medical care that can identify and treat the conditions that contribute to harmful inflammation.

Polio is a potentially life-threatening or disabling illness that spreads from person to person. Thanks to vaccination, the United States has been polio-free since 1979, and the spread of this highly contagious disease has been interrupted in most countries. Yet on June 22, the United Kingdom Health Security Agency announced that it had detected poliovirus in a most unexpected place: the sewers of London.

Over the past several months, scientists at the agency repeatedly found poliovirus in London sewer water. The viruses were genetically similar, suggesting that they were the result of limited spread within a family or close-knit community. Just how concerned should all of us be about this news?

Health clues found in wastewater

Sampling of wastewater for genetic material from viruses is a powerful tool used by epidemiologists to track outbreaks of polio and other diseases. Surges in the amount of SARS-CoV-2 RNA in Boston wastewater have been highly predictive of COVID outbreaks. Wastewater may also help to detect the spread of influenza and antibiotic-resistant bacteria.

Poliovirus infection was once a common and dreaded disease. Most people with poliovirus either had no symptoms or mild gastroenteritis (stomach flu). But one in 100 people developed paralysis, or poliomyelitis. In half of the affected patients, this paralysis was permanent.

In the UK, wild poliovirus has been eliminated since 1984. Although great progress has been made in many parts of the world, complete eradication of polio has been elusive. Pakistan and Afghanistan have never been free from wild-type polio, and outbreaks have recently taken place in Malawi and Mozambique, countries which had previously eliminated polio.

The reasons for this backsliding are complex. Some contributing factors are diversion of scarce resources toward the COVID-19 pandemic, backlogs in vaccine manufacturing, anti-vaccine agitation, and violence directed at vaccine workers.

Another problem is vaccine-derived poliovirus. In the United States and most other countries, injections containing killed viruses are used. While these vaccines are safe, they are less effective than oral vaccines at breaking the chain of polio transmission. Oral vaccines stimulate long-lived immune responses in the lining of the intestines, where polioviruses replicate. Unfortunately, oral vaccines contain weakened but live viruses, which occasionally revert to a more dangerous form. In fact, the poliovirus found in London was a vaccine-derived strain that the infected individual had likely acquired from travel abroad.

Who is at risk for poliovirus stemming from this source?

Vaccine-derived viruses pose little risk to highly vaccinated populations, but they are able to spread in communities with low polio vaccination rates. In some cases, this can even cause paralytic disease. Because of these risks, steps are being taken to gradually phase out the use of oral polio vaccines.

If you’re concerned about polio, the best protection against this disease is vaccination. Children should receive a full series of four shots of inactivated polio vaccine, given at specific intervals, that helps with developing immunity.

Nationwide, rates of childhood polio vaccination in the United States are still high (nearly 93%). However, some infectious disease experts worry that the weakening of vaccine mandates in some areas has created islands of vulnerability in this sea of immunity. Communities in the US with low childhood vaccination rates have been vulnerable to large measles outbreaks in recent years, and might also be vulnerable to polio outbreaks.

With few exceptions, adults who were fully vaccinated as kids do not need booster shots. These exceptions include travel to a country with active polio transmission, laboratory work with poliovirus, or providing health care to polio patients and their close contacts. A single lifetime booster dose of inactivated polio vaccine is adequate for these high-risk scenarios.

Many people seek medical attention when they have diarrhea, usually when it is severe or is not improving. Doctors like myself ask questions to see what could be causing the problem: Food poisoning? Irritable bowel syndrome? Medication side effects? We also consider that diarrhea may be due to Clostridioides difficile infection (CDI).

What is C. diff infection?

CDI is a bacterial infection that can cause severe problems in the gastrointestinal tract, especially the colon. C. diff is responsible for almost half a million infections in the US each year, and it can be a recurring problem: one in six patients with this infection will get it again within two months. Sadly, one in 11 patients over age 65 who is hospitalized for CDI will die within one month of infection due to the severity of illness in CDI. Therefore, CDI is an important public health consideration, and it’s important to get treatment.

Who at risk for C. diff infection?

There are certain risk factors for developing a CDI. These include being hospitalized, having been exposed to antibiotics, or having close contact with someone who has been diagnosed with the infection. If you are immunocompromised (have a weakened immune system), you may be also at higher risk of contracting CDI or of suffering a complication from it.

A major focus of reducing the burden of CDI in the healthcare system is trying to reduce the risk of getting CDI in the hospital. This includes testing for CDI in hospitalized patients who develop new diarrhea, and then isolating those patients into their own rooms.

Prevention also includes washing your hands thoroughly with soap and water. This is a particularly important point because in healthcare settings, alcohol-based sanitizer often is used for convenience when clinicians practice preventive infection control between caring for patients. Alcohol-based sanitizer is not effective against CDI as it is for other types of infection because, unlike other bacteria, C. diff organisms can form resistant spores.

So, to protect yourself in health care settings, you should make sure the people who interact with you — doctors, nurses, medical assistants, etc. — have washed their hands prior to touching you. It can seem rude to ask someone if they have washed their hands. However, all people who work with patients receive training about hand-washing, and sometimes we simply forget in the middle of busy days, so it can be helpful to remind us.

What about CDI transmission outside of medical settings?

What is less understood is when CDI happens outside the hospital. A recent article in Emerging Infectious Diseases reported the presence of CDI in patients who became infected in a way that doctors tend not to think of as often: getting CDI from someone they know without ever being hospitalized or taking antibiotics themselves.

As physicians, we are drilled on the factors previously mentioned — prior use of antibiotics, previous hospitalization — as critical events that may cause CDI. What this research demonstrated is that people without these risk factors developed CDI by being exposed to someone with CDI in the community. It turns out that this is a common way people end up contracting CDI. During my training, we learned that it is important to remind patients newly diagnosed with CDI to be mindful of good hand hygiene, and to avoid as many contacts as possible until their CDI treatments were completed. This new research suggests that focusing on community CDI transmission should be a greater priority.

How is CDI treated?

The first round of CDI treatment is usually antibiotics (ironic, since antibiotics can cause CDI). These include metronidazole, vancomycin (in oral form only), and fidaxomicin. Every few years guidelines are reviewed and updated, but generally, different antibiotic treatment courses are given based on CDI illness severity, whether there is an infection that is failing to clear, or if a new antibiotic needs to be tried.

A promising way to treat CDI, particularly in patients who have not been helped by antibiotic therapy, is to give a fecal microbiota transplant, or FMT. This treatment involves taking a healthy person’s stool donation and administering it during an endoscopy procedure by mouth, during a colonoscopy, or in frozen form by pill. I know — taking someone else’s poop sounds so icky! However, the purpose is to introduce healthy bacteria into a gut that is sick with CDI, and the theory is that these healthy bacteria expand and make the environment harder for the C. diff bacteria to live and cause problems.

What precautions help prevent spread ofCDI?

The rules are simple for reducing your risk of CDI. If you have a weakened immune system, stay away from people who have been diagnosed with CDI. Thoroughly wash your hands with soap and water (not disinfectant) to deal with C. diff spores more effectively. When you are sick, take antibiotics only if they are necessary; doctors often feel pressured to write antibiotic prescriptions for people who have viral illnesses (for which antibiotics do not work).

Evidence is not strong for taking probiotics or eating yogurt to prevent CDI, but these approaches are low-risk ways to introduce healthy bacteria into your gut; this may be reasonable, in part because some in the medical field continue to debate their effectiveness.

Bottom line: if you are having diarrhea that just won’t go away, talk to your doctor to see if you have CDI or if there is something else causing your symptoms.

Proponents of cannabis generally dismiss the idea that there is a cannabis withdrawal syndrome. One routinely hears statements such as, “I smoked weed every day for 30 years and then just walked away from it without any problems. It’s not addictive.” Some cannabis researchers, on the other hand, describe serious withdrawal symptoms that can include aggression, anger, irritability, anxiety, insomnia, anorexia, depression, restlessness, headaches, vomiting, and abdominal pain. Given this long list of withdrawal symptoms, it’s a wonder that anyone tries to reduce or stop using cannabis. Why is there such a disconnect between researchers’ findings and the lived reality of cannabis users?

New research highlights the problems of withdrawal, but provides an incomplete picture

A recent meta-analysis published in JAMA cites the overall prevalence of cannabis withdrawal syndrome as 47% among “individuals with regular or dependent use of cannabinoids.” The authors of the study raise the alarm that “many professionals and members of the general public may not be aware of cannabis withdrawal, potentially leading to confusion about the benefits of cannabis to treat or self-medicate symptoms of anxiety or depressive disorders.” In other words, many patients using medical cannabis to “treat” their symptoms are merely caught up in a cycle of self-treating their cannabis withdrawal. Is it possible that almost half of cannabis consumers are actually experiencing a severe cannabis withdrawal syndrome — to the point that it is successfully masquerading as medicinal use of marijuana — and they don’t know it?

Unfortunately, the study in JAMA doesn’t seem particularly generalizable to actual cannabis users. This study is a meta-analysis: a study which includes many studies that are deemed similar enough to lump together, in order to increase the numerical power of the study and, ideally, the strength of the conclusions. The authors included studies that go all the way back to the mid-1990s — a time when cannabis was illegal in the US, different in potency, and when there was no choice or control over strains or cannabinoid compositions, as there is now. One of the studies in the meta-analysis included “cannabis-dependent inpatients” in a German psychiatric hospital in which 118 patients were being detoxified from cannabis. Another was from 1998 and is titled, “Patterns and correlates of cannabis dependence among long-term users in an Australian rural area.” It is not a great leap to surmise that Australians in the countryside smoking whatever marijuana was available to them illegally in 1998, or patients in a psychiatric hospital, might be substantively different from current American cannabis users.

Medical cannabis use is different from recreational use

Moreover, the JAMA study doesn’t distinguish between medical and recreational cannabis, which are actually quite different in their physiological and cognitive effects, as Harvard researcher Dr. Staci Gruber’s work tells us. Medical cannabis patients, under the guidance of a medical cannabis specialist, are buying legal, regulated cannabis from a licensed dispensary; it might be lower in THC (the psychoactive component that gives you the high) and higher in CBD (a nonintoxicating, more medicinal component), and the cannabis they end up using often results in them ingesting a lower dose of THC.

Cannabis withdrawal symptoms are real

All of this is not to say that there is no such thing as a cannabis withdrawal syndrome. It isn’t life-threatening or medically dangerous, but it certainly does exist. It makes absolute sense that there would be a withdrawal syndrome because, as is the case with many other medicines, if you use cannabis every day, the natural receptors by which cannabis works on the body “down-regulate,” or thin out, in response to chronic external stimulation. When the external chemical is withdrawn after prolonged use, the body is left in the lurch, and forced to rely on natural stores of these chemicals, but it takes time for the natural receptors to grow back to their baseline levels. In the meantime, the brain and the body are hungry for these chemicals, and the result is withdrawal symptoms.

Getting support for withdrawal symptoms

Uncomfortable withdrawal symptoms can prevent people who are dependent on or addicted to cannabis from remaining abstinent. The commonly used treatments for cannabis withdrawal are either cognitive behavioral therapy or medication therapy, neither of which has been shown to be particularly effective. Common medications that have been used are dronabinol (which is synthetic THC); nabiximols (which is cannabis in a mucosal spray, so you aren’t actually treating the withdrawal); gabapentin for anxiety (which has a host of side effects); and zolpidem for the sleep disturbance (which also has a list of side effects). Some researchers are looking at CBD, the nonintoxicating component of cannabis, as a treatment for cannabis withdrawal.

Some people get into serious trouble with cannabis, and use it addictively to avoid reality. Others depend on it to an unhealthy degree. Again, the number of people who become addicted or dependent is somewhere between the 0% that cannabis advocates believe and the 100% that cannabis opponents cite. We don’t know the actual number, because the definitions and studies have been plagued with a lack of real-world relevance that many studies about cannabis suffer from, and because the nature of both cannabis use and cannabis itself have been changing rapidly.

How do you know if your cannabis use is a problem?

The standard definition of cannabis use disorder is based on having at least two of 11 criteria, such as: taking more than was intended, spending a lot of time using it, craving it, having problems because of it, using it in high-risk situations, getting into trouble because of it, and having tolerance or withdrawal from discontinuation. As cannabis becomes legalized and more widely accepted, and as we understand that you can be tolerant and have physical or psychological withdrawal from many medicines without necessarily being addicted to them (such as opiates, benzodiazepines, and some antidepressants), I think this definition seems obsolete and overly inclusive.

For example, if one substituted “coffee” for “cannabis,” many of the 160 million Americans who guzzle coffee on a daily basis would have “caffeine use disorder,” as evidenced by the heartburn and insomnia that I see every day as a primary care doctor. Many of the patients that psychiatrists label as having cannabis use disorder believe that they are fruitfully using cannabis to treat their medical conditions — without problems — and recoil at being labeled as having a disorder in the first place. This is perhaps a good indication that the definition doesn’t fit the disease.

Perhaps a simpler, more colloquial definition of cannabis addiction would be more helpful in assessing your use of cannabis: persistent use despite negative consequences. If your cannabis use is harming your health, disrupting your relationships, or interfering with your job performance, it is likely time to quit or cut down drastically, and consult your doctor. As part of this process, you may need to get support or treatment if you experience uncomfortable withdrawal symptoms, which may make it significantly harder to stop using.

Asthma is the most common chronic lung disease in children. In the US, it affects about 6 million children, or about one in every 12 children.

Breathing is key to life, obviously, so asthma can make life very hard. It can make going for a walk outside feel very hard. It leads not just to visits with the doctor or to the emergency room, and to hospitalizations, but also to missed school, missed work for parents, missed events, and missed activities.

The good news is that asthma is very treatable. If parents, children, and doctors work together, a child with asthma can lead a healthy, normal life. Here’s what you need to know and do.

Know your child’s symptoms

Wheezing is definitely a symptom of asthma, but a dry persistent cough can be as well (for some children, this occurs mostly at night).

Watch for signs that a child is working harder to breathe. One sign is skin tugging inward between, on top of, or below the ribs. Difficulty talking in long sentences is another sign of this.

Some children with exercise-induced asthma avoid exercise; if your child is choosing to be less active, talk to them about why.

Know your child’s triggers

There are many different triggers for asthma, including:

• Upper respiratory infections, like the common cold. COVID falls into this category, which is why children with asthma should be vaccinated against COVID.
• Allergies, such as
  • outdoor allergens like pollen, which are often worse in the spring and fall
  • indoor allergens like dust mites or mold
  • pet dander.
• Exercise. Some children will struggle with even mild exercise, while others only have trouble with vigorous exercise or exercising when there are other triggers too (like a cold or allergies).
• Weather changes, especially to colder weather. Some children can be triggered by going into a cold, air-conditioned room.
• Stress. Stress affects our bodies in multiple ways, and in some people it can trigger their asthma or make it worse.

Understand your child’s medications

Several kinds of medicines are used to treat asthma, including:

• Bronchodilators. Examples are albuterol, levalbuterol, formoterol, or ipratropium. Known as “rescue medications,” these are inhaled and work by opening up the airways. They are given through metered-dose inhalers or a nebulizer machine. They are used when a person is experiencing symptoms.
• Inhaled steroids. These work by decreasing inflammation in the lungs and making them less likely to react to triggers. They are “controller medications” given regularly to prevent symptoms.
• Combined inhalers. These have both an inhaled steroid and a long-acting bronchodilator. They are very useful for patients with more difficult asthma. Sometimes they are used in SMART (Single Maintenance And Reliever Therapy), in which the same inhaler is used for both rescue and control.
• Oral or injected steroids. These are generally used when someone has a bad asthma attack, but some people need to take them regularly to prevent attacks.
• Allergy medications. Medicines like loratadine, cetirizine, or montelukast can be very helpful when there is an allergic component to asthma.

Some people with severe asthma need other treatments, such as allergy shots for severe allergies, or medications like dupilumab that work in the body to flight inflammation. This is far less common.

Use medication correctly

• Sometimes medications and medication regimens can be confusing. That’s why everyone with asthma should have a written Asthma Action Plan that spells out exactly what they should do and when.
• If your child uses an inhaler, make sure that they are doing it right! For most inhalers, it’s important to use a spacer, which is a tube that attaches to the inhaler and helps to ensure that the medication gets into the lungs and not just the mouth or surrounding air.
• If you have any questions about anything your child is prescribed, call your doctor.

Meet with your doctor regularly

If your child’s asthma is anything more than very mild (a few mild attacks a year), you need to check in more frequently than at the yearly checkup. Extra check-ins give you a chance to talk to your doctor about how things are going — and give your doctor a chance to tweak your child’s regimen so that your child can live the healthiest, happiest life possible.

Which, after all, is totally the point.

Growing evidence suggests that poor sleep is linked to a host of health problems, including a higher risk of high blood pressure, diabetes, obesity, and heart disease. Now, a recent study on people in midlife finds that having a combination of sleep problems — such as trouble falling asleep, waking up in the wee hours, or sleeping less than six hours a night — may nearly triple a person’s risk of heart disease.

"These new findings highlight the importance of getting sufficient sleep," says sleep specialist Dr. Lawrence Epstein, assistant professor of medicine at Harvard Medical School. Many things can contribute to a sleep shortfall, he adds. Some people simply don’t set aside enough time to sleep. Others have habits that disrupt or interfere with sleep. And some people have a medical condition or a sleep disorder that disrupts the quality or quantity of their sleep.

Who was in the study?

The researchers drew data from 7,483 adults in the Midlife in the United States Study who reported information about their sleep habits and heart disease history. A subset of the participants (663 people) also used a wrist-worn device that recorded their sleep activity (actigraphy). Slightly more than half of participants were women. Three-quarters reported their race as white and 16% as Black. The average age was 53.

Researchers chose to focus on people during midlife, because that’s when adults usually experience diverse and stressful life experiences in both their work and family life. It’s also when clogged heart arteries or atherosclerosis (an early sign of heart disease) and age-related sleep issues start to show up.

How did researchers assess sleep issues?

Sleep health was measured using a composite of multiple aspects of sleep, including

• regularity (whether participants slept longer on work days versus nonwork days)
• satisfaction (whether they had trouble falling asleep; woke up in the night or early morning and couldn’t get back to sleep; or felt sleepy during the day)
• alertness (how often they napped for more than five minutes)
• efficiency (how long it took them to fall asleep at bedtime)
• duration (how many hours they typically slept each night).

To assess heart-related problems, researchers asked participants "Have you ever had heart trouble suspected or confirmed by a doctor?" and "Have you ever had a severe pain across the front of your chest lasting half an hour or more?"

A "yes" answer to either question prompted follow-up questions about the diagnosis, which included problems such as angina (chest pain due to lack of blood flow to the heart muscle), heart attack, heart valve disease, an irregular or fast heartbeat, and heart failure.

Poor sleep linked to higher heart risk

The researchers controlled for factors that might affect the results, including a family history of heart disease, smoking, physical activity, as well as sex and race. They found that each additional increase in self-reported sleep problems was linked to a 54% increased risk of heart disease compared to people with normal sleep patterns. However, the increase in risk was much higher — 141% — among people providing both self-reported and wrist-worn device actigraphy data, which together are considered more accurate.

Although women reported more sleep problems, men were more likely to suffer from heart disease. But overall, sex did not affect the correlations between sleep and heart health.

Black participants had more sleep and heart-related problems than white participants, but in general, the relationship between the two issues did not differ by race.

What does this mean for you?

If you have trouble falling or staying asleep, there are many ways to treat these common problems, from simple tweaks to your daily routine to specialized cognitive behavioral therapy that targets sleep issues. These are well worth trying, because getting a good night’s sleep helps in many ways.

"Treating sleep disorders that interfere with sleep can make you feel more alert during the day, improve your quality of life, and reduce the health risks related to poor sleep," says Dr. Epstein.

Acne can be frustrating, especially when it does not go away after your teenage years. Believe it or not, acne can continue to affect adults beyond adolescence, or develop for the very first time in adulthood. This may be particularly distressing for adult women, who are more likely to get acne after the age of 20 compared to men.

What is adult female acne?

Adult female acne can look very similar to teenage acne. While adult acne is commonly thought to affect the jawline and chin, it can appear on any part of the face or trunk. Adult women can have clogged pores, inflamed pus-filled bumps, or deep-seated cysts. Unfortunately, treatment options that worked well in the teenage years may not work as well in adult females with acne, due to triggering factors such as hormonal imbalance, stress, and diet.

There are many reasons adult females can get acne. Hormonal disturbances caused by pregnancy, menstrual cycle, menopause, and oral contraceptives can contribute to acne by modifying the production of certain hormones. These hormones stimulate oil production within the skin, promoting the growth of acne-causing bacteria. Stress can increase the production of substances that activate oil glands within the skin of acne patients. Consumption of dairy and high-glycemic foods is also linked to acne. Certain hair or skin products can clog pores and cause comedonal acne (blackheads and whiteheads). A board-certified dermatologist can help determine the appropriate treatment for the type of acne you have.

Consequences of adult acne and scarring

The extent to which acne causes emotional distress varies, and is not related to the severity of the acne or acne scars. Some women with acne may experience disruption in their personal and professional lives as they fear stigmatization in relationships and employment. Adult females may also be more likely to seek treatment for active acne when acne bumps and scarring persist.

Acne scarring can be disfiguring. Permanent changes in skin texture in the form of pits or raised scars may not be easily concealed with makeup. Raised scars may also lead to skin picking and worsening skin texture and pigment.

Acne can also heal with red or dark spots that may not resolve for weeks to months. The dark spots may persist even longer without proper sun protection, especially on darker skin. Having both acne and dark spots may negatively impact one’s quality of life and self-perception.

The emotional toll associated with acne may include an elevated risk of developing depression compared to patients who do not have acne. Clinical studies show that having severe acne can negatively affect quality of life on par with long-term diseases such as arthritis, diabetes, back pain, and asthma. If you have acne, extensive scarring, or dark spots of any severity that are affecting your mental health, you may benefit from earlier intervention with oral medications.

What are options for treatment and support?

Acne is a medical condition, but it only needs to be treated if the acne or marks left behind from it are bothersome to you. Please see a board-certified dermatologist (in person or virtually) for the best available options if you wish to seek treatment.

Your dermatologist may prescribe a combination of topical (skin) and oral treatments. Some of these medications may not be appropriate if you are pregnant or breastfeeding, or carry risks. Ask your dermatologist about hair and skin products that may be irritating, clogging pores, or promoting oil production in the skin, making your acne worse. Also, avoid skin picking to prevent scarring, and try to minimize emotional and physical stressors.

For individuals with dark spots or scarring, consult a board-certified dermatologist to get a personalized treatment geared to your skin concerns. Use a broad-spectrum, tinted sunscreen daily and reapply it every two hours to help prevent acne marks from worsening. If your acne is causing you significant mental distress, ask your doctor about mental health resources. Additionally, seeking treatment for your acne may help you feel better. Consider joining online or in-person support groups in your area.

Music boosts our mood and well-being, and music therapy may help during treatments for certain health conditions.

Times are hard. The current political climate, war, impact of global warming, continued inequities due to systemic racism, and ongoing physical and mental health challenges from COVID are taking a toll on our feelings of safety in the world and quality of life. Hopefully, each of us can find moments of ease and temporarily shift our thoughts away from the difficult daily news. For many people, music can play a role in making that shift, even incrementally.

How can music impact our quality of life?

Recently, researchers looked at the impact of music interventions on health-related quality of life, and tried to answer the question about the best way to help make that shift toward release, relaxation, and rehabilitation. This recent systematic review and meta-analysis (a study of studies) showed that the use of music interventions (listening to music, singing, and music therapy) can create significant improvements in mental health, and smaller improvements in physical health–related quality of life. While the researchers found a positive impact on the psychological quality of life, they found no one best intervention or “dose” of music that works best for all people.

Complexities of music

As complex human beings from a wide variety of cultures, with a variety of life experiences and mental and physical health needs, our connection with music is very personal. Our relationship with music can be a very beautiful, vulnerable, and often complicated dance that shifts from moment to moment based on our mood, preferences, social situation, and previous experiences. There are times where music can have a clear and immediate impact on our well-being:

• easing a transition to sleep with a soothing playlist
• finding motivation for exercise by listening to upbeat dance music
• aiding self-expression of emotions by singing
• connecting to others by attending a live musical performance.

There are other times when a board-certified music therapist can help you build that connection to music, and find the best intervention and “dose” that could positively impact your health and provide a form of healing.

How can music be used as a therapeutic tool?

Music therapy is an established health care profession that uses evidence-based music interventions to address therapeutic health care goals. Music therapy happens between a patient (and possibly their caregivers and/or family) and a board-certified music therapist who has completed an accredited undergraduate or graduate music therapy program.

Music therapists use both active (singing, instrument exploration, songwriting, movement, digital music creation, and more) and receptive (music listening, guided imagery with music, playlist creation, or music conversation and reminiscence) interventions, and create goals to improve health and well-being.

Some of those goals could include decreasing anxiety, shifting your mood, decreasing pain perception during cancer or other medical treatment, increasing expression, finding motivation, and many others. The approach to using music to achieve these kinds of goals — and to improving your quality of life in general — can shift from moment to moment, and a music therapist can help you find what works best for a particular situation.

My top music therapy tools

Listening

This intervention has been studied the most, in almost every scenario. It can be done either on your own or in music therapy. The music can be live or recorded. Listening can be done with intentional focus or as background listening. You can amplify emotions for release. You can use music to quiet the mind. Or you can utilize the “iso principle” and match music to your current energy or mood, and then slowly change feel, tempo, and complexity to help you shift. Music listening can be paired with prompts for relaxation, or to motivate you to exercise, move more, or do a task you’ve been putting off.

Learning or playing an Instrument

Active music-making truly engages your entire brain. This creates the most potential for distraction, pain reduction, cognition, fine and gross motor development, and expression. Some instruments are designed for easier access to free expression or learning.

A steel tongue drum, for example, set up in a pentatonic scale, has a beautiful resonant sound, has no “wrong notes,” and by design allows you to just play! If you want to engage your cognitive brain a bit, try learning the ukulele. The strings are easy to push, beginner chords only need one or two fingers, and there are many great ukulele resources online. Making music with an instrument can be fun and easy.

A board-certified music therapist can help you find the most direct and success-based path to musical expression. Learning how to really master an instrument and read music takes time, patience, and practice.

Singing

This can be an amazing intervention if you have a good connection to your voice and/or have a good music therapy relationship where the therapist can help you build your connection to your instrument. There are physical benefits of singing on lung function and emotional benefits of singing lyrics that speak your truth. Finally, there is the community connection and power of being surround by strong, tight harmonies.

The bottom line

Although there is not one best intervention, magical song, or perfect genre to make all the hard things in life easier, music can be a powerful agent of change.

I recently learned about a study suggesting a vegan diet is an effective treatment for rheumatoid arthritis.

While that sounded intriguing, another claim made in an interview about the study really caught my attention: the lead author of the study said that physicians should encourage people with rheumatoid arthritis to try changing their eating patterns before turning to medication.

Before turning to medication? Now wait just a minute. That flies in the face of decades of research convincingly demonstrating the importance of early medication treatment of rheumatoid arthritis to prevent permanent joint damage. An increasing number of effective treatments can do just that.

In fact, there’s no convincing evidence that changes in diet can prevent joint damage in rheumatoid arthritis. And that includes this new study.

So, what did this research find? Let’s take a look.

A vegan diet for rheumatoid arthritis

Researchers enrolled 44 people with rheumatoid arthritis in the study. All were women, mostly white and highly educated. They were randomly assigned to one of two groups for 16 weeks:

• Vegan diet. Participants followed a vegan diet for four weeks, followed by additional food restrictions that eliminated foods the researchers considered to be common arthritis trigger foods. These foods included gluten-containing grains (wheat, barley, and rye), white potatoes, sweet potatoes, chocolate, citrus fruits, nuts, onions, tomatoes, apples, bananas, coffee, alcohol, and table sugar. After week seven, these foods were reintroduced, one at a time. Any reintroduced food that seemed to cause pain or other symptoms of rheumatoid arthritis was eliminated for the rest of the 16-week period.
• Usual diet plus placebo. These participants followed their usual diet and took a placebo capsule each day for 16 weeks. The capsule contained insignificant doses of omega-3 fatty acids and vitamin E.

After the first 16 weeks, participants took four weeks off, then the groups swapped dietary assignments for an additional 16 weeks.

What did the study find about the vegan diet?

The vegan approach seemed to help lessen arthritis symptoms. Study participants reported improvement while on the vegan diet, but no improvement during the placebo phase.

For example, the average number of swollen joints fell from 7 to 3.3 in the vegan diet group, but actually increased (from 4.7 to 5) in the placebo group. In addition, while on the vegan diet, participants lost an average of 14 pounds, while those on the placebo gained nearly 2 pounds.

What else do we need to consider?

While the findings sound great, the study had significant limitations:

• Size. Only 44 study subjects enrolled and only 32 completed the study. With such small numbers, it only takes a few to alter the results. Larger studies (with several hundred or more participants) tend to be more reliable.
• Lack of diversity. This trial did not include men and had mostly white, highly educated participants.
• No standard diagnosis of rheumatoid arthritis. A physician’s diagnosis was required, but there was no requirement that standard criteria be met.
• Study duration. A treatment lasting four months may seem like a long time, but for a chronic disease like rheumatoid arthritis that can wax and wane on its own, this is too short a time to make firm conclusions.
• Self-reported diet. We don’t know how well study subjects stuck to their assigned diets.
• Medication use. Study subjects took arthritis medications, though no information on specific drugs is offered. Some made dosage adjustments during the trial. While the researchers tried to account for this through a separate analysis, the small number of participants could make that analysis unreliable.
• Weight loss. Losing weight, rather than eating a vegan diet, might have contributed to symptom improvement.
• No assessment of joint damage. No x-rays, MRI results, or other assessments of joint damage were provided. That’s important, because we know that people with arthritis can feel better even when joint damage continues to worsen. Steroids and ibuprofen are good examples of treatments that reduce symptoms of rheumatoid arthritis without protecting the joints. Without information about joint damage, it’s impossible to assess the true benefit or risk of relying on a vegan diet to treat rheumatoid arthritis.

Finally, it’s unclear how a vegan diet would improve rheumatoid arthritis. This raises the possibility that the findings won’t hold up.

Should everyone with rheumatoid arthritis become vegan?

No, there isn’t enough evidence to justify recommending a vegan diet — or any restrictive diet — for everyone with rheumatoid arthritis.

That said, a plant-rich diet is healthy for nearly everyone. As long your diet is nutritionally balanced and palatable to you, I see little harm in adopting an anti-inflammatory diet. But in the case of rheumatoid arthritis, diet should be combined with medicationto prevent joint damage, not used instead of it.

The bottom line

Growing evidence suggests diet can play a role in treating rheumatoid arthritis. But it’s one thing for a person to feel better on a particular diet; it’s quite another to say diet is enough by itself.

For high cholesterol or high blood pressure, dietary changes are the first choice of treatment. But rheumatoid arthritis is different. Disabling joint damage can occur early in the disease, so it’s important to start taking effective medications as soon as possible to prevent this.

We will undoubtedly see more research exploring the impact of diet on rheumatoid arthritis, other forms of arthritis, and other autoimmune disorders. Perhaps we’ll learn that a vegan diet is highly effective and can take the place of medications in some people. But we aren’t there yet.
