Gun violence: A long-lasting toll on children and teens

A classroom with several rows of empty desks and chairs in front of large-multipaned windows

In the aftermath of the killing of 19 children and two adults in an elementary school in Uvalde, Texas, there is a lot of discussion — and argument — about what we should do to prevent shootings like this from happening.

In the midst of all the back and forth between banning guns and arming teachers, there is an important question that cannot be lost: what does it do to a generation of children to grow up knowing that there is nowhere they are safe?

There is increasing research that growing up amidst violence, poverty, abuse, chronic stress, or even chronic unpredictability affects the brains and bodies of children in ways that can be permanent. These adverse childhood experiences put the body on high alert, engaging the flight-or-fight responses of the body in an ongoing way. This increases the risk of depression, anxiety, and substance abuse, but it does so much more: the stress on the body increases the risk of cancer, heart disease, chronic disease, chronic pain, and even shortens the lifespan. The stress on the brain can literally change how it is formed and wired.

Long-term effects on a generation

Think for a moment about what this could mean: an entire generation could be forever damaged in ways we cannot change. The ramifications, not just for their well-being but for future generations and our work force and health care system, are staggering: stress like this can be passed on, and affects parenting.

As we talk about arming teachers and increasing armed police at schools, it is important to remember that research shows that the more guns, the higher the risk of homicide. It’s also important to remember that many children die every year from unintentional shootings in the home. In fact, guns have overtaken motor vehicle accidents as the leading cause of death in children. The idea of “arming the good guys” is an understandable response to horrible events like Uvalde, Parkland, and Sandy Hook, but the data would suggest that it may not be the most successful one. Violence begets violence, and guns aren’t reliably used the way we want them to be.

It’s not just guns, of course. There are other stressors, like poverty, community violence, child abuse, racism and all the other forms of intolerance, and lack of access to health care and mental health care. The pandemic has likely forever altered this generation in ways we cannot change, too.

The communities our children are growing up in and the world they are growing up in are increasingly becoming scary places. If we care about our children, if we care about our future, we need to stop fighting among ourselves and come together to create solutions that support the health and well-being of children, families, and communities. We need to nurture our children, not terrify them.

Thunderstorm asthma: Bad weather, allergies, and asthma attacks

photo of a stormy night sky with multiple flashes of lightning spiking down from dark clouds over city lights and a blurry line of highway lights

It’s an old line: everyone complains about the weather but no one is doing anything about it.

But if you’re a person with bad allergies or asthma, stormy weather can be more than an annoyance; it can be a serious threat to your health. “Thunderstorm asthma” was first reported in the 1980s in England and Australia, and cases continue to crop up. Just after severe thunderstorms passed through Melbourne, Australia in 2016, more than 9,000 people sought urgent medical care for asthma during one notable event. Medical facilities were overwhelmed and at least eight people died. That’s unusual, but if you do have asthma — or seasonal allergies, as it turns out — understanding this trigger can help you stay well.

What is thunderstorm asthma?

The term describes an attack of asthma that starts or worsens after a thunderstorm. It can occur in anyone with asthma, but it most often affects people with seasonal allergic rhinitis, which many people know as hay fever or allergies. Heralded by a runny nose, sneezing, and itchy eyes, seasonal allergies are often worst in the spring, summer, or early fall.

Rain tends to lower pollen counts by cleansing the air, and many people find that rainy weather tends to reduce asthma symptoms triggered by allergies. But thunderstorms can make asthma worse because of a unique sequence of events:

  • Cold downdrafts concentrate air particles, such as pollen and mold
  • These air particles are swept up into clouds where humidity is high
  • In the clouds, wind, humidity, and lightning break up the particles to a size that can readily enter the nose, sinuses, and lungs
  • Wind gusts concentrate these small particles so large amounts can be inhaled.

What raises risk for experiencing thunderstorm asthma?

According to a new study in the Journal of Allergy and Clinical Immunology, a whopping 144 out of 228 people with seasonal allergies reported experiencing thunderstorm asthma — that’s 65%! And many of the asthma attacks set off by thunderstorms weren’t mild. Nearly half of people who had an attack sought emergency hospital treatment.

Among people with seasonal allergies, risk factors for experiencing thunderstorm asthma include having

  • poorly controlled asthma symptoms (assessed by a standard asthma questionnaire)
  • a low score on a rapid exhalation test (a common breathing test for asthma)
  • higher levels of a certain antibody (ryegrass pollen-specific IgE)
  • higher numbers of certain blood cells (eosinophils, which tend to increase when people have allergic conditions)
  • higher levels of exhaled nitric oxide (one measure of lung inflammation among people with asthma).

Not everyone with these risk factors will develop thunderstorm asthma. And even among those who do, asthma attacks won’t necessarily occur with every storm. But it may be useful to know if you’re among those at risk, especially if you live in an area where thunderstorms are common.

The bottom line

Thunderstorm asthma may seem like more of a curiosity than a serious threat to public health. But when it affects a large population area, emergency rooms can become overwhelmed, as happened during the 2016 Melbourne event. A better understanding of when these events are expected could lead to advanced warning systems, enhanced emergency room preparedness, and even preventive treatment.

In the US, 25 million people have asthma and more than 20 million have seasonal allergies. Odds are good that millions have both, which puts large numbers of people at risk for developing thunderstorm asthma.

If you’re among them, the weather forecast may be much more than just a guide on what to wear or whether to bring an umbrella. Knowing thunderstorms are headed your way may serve as an advance warning to double check that you are taking your asthma medicines properly, have a supply of rescue medicine handy, or simply plan to stay indoors until the storm has passed.

Struggling with migraine hangovers? Read this

Bright yellow background and pink silhouette print of a woman from the shoulders up, wearing glasses and looking pained, head slightly tipped and the fingers of one hand on her temple

When the trademark throbbing from a migraine finally lifts, the relief is profound. But for many people regularly stricken with these potentially debilitating headaches, their distress isn’t over just because the pain ends. Instead, a distinct phase of migraine called the postdrome leaves them feeling achy, weary, dazed, and confused — symptoms eerily similar to another affliction altogether.

Dubbed the “migraine hangover,” this constellation of post-headache symptoms is remarkably common, following up to 80% of migraine attacks, according to research published in Neurology. Scientists are increasingly turning their focus to this previously underrecognized component of migraine, according to Dr. Paul Rizzoli, clinical director of the Graham Headache Center at Brigham and Women’s Faulkner Hospital.

“Not knowing it’s an accepted part of migraine, patients come up with some creative ways to tell us about their postdrome symptoms — they feel washed out, their head feels hollow, or they feel like they have a hangover but weren’t even drinking,” Dr. Rizzoli explains. “Until recent years, science hadn’t paid attention to this facet of the syndrome, but it’s a natural progression from focusing on the problem as a whole.”

The four phases of migraine

The typical migraine can be a wretched experience, with stabbing head pain joined by nausea, brain fog, and extreme sensitivity to light and sound, among other symptoms. Nearly 16% of Americans are affected by migraines, which strike women at nearly twice the rate as men. Severe headaches are also one of the top reasons for emergency room visits.

Spanning hours to days, migraine headaches can include four clear phases, each with its own set of symptoms. The pre-pain prodrome and aura phases may include various visual changes, extremes of irritability, difficulty speaking, or numbness and tingling, while the headache itself can feel like a drill is working its way through the skull.

Lingering migraine symptoms: The hangover

After that ordeal, one to two days of postdrome symptoms may sound tame by comparison, Dr. Rizzoli says. But the lingering fogginess, exhaustion, and stiff neck can feel just as disabling as the headache that came before. Since migraine is believed to act as a sort of electrical storm activating neurons in the brain, it’s possible that migraine hangover results from “some circuits being electrically or neurochemically exhausted,” Dr. Rizzoli says. “It just takes time for the brain to return to normal function, or even replace some chemicals that have been depleted in the process.”

But much is still unknown about migraine postdrome, he adds, and research has found no consistent association between factors such as the type of migraine medication taken and duration of any subsequent hangover.

Tips to ease a migraine hangover

Following these steps regularly may help you ward off lingering symptoms after a migraine:

  • Drink plenty of water.
  • Practice good headache hygiene by maintaining regular eating and sleeping patterns and easing stress.
  • If possible, try to lighten your load for next 24 hours after the headache pain ends.
  • Stop taking pain medicine once the headache is gone.

For migraine hangover sufferers so distracted by their inability to return to normal activities even after migraine pain lifts, physicians sometimes prescribe medications typically meant for conditions such as memory loss, depression, or seizures. While they may differ from the usual drugs used to treat migraine, some of these medicines have been observed to help postdrome syndrome or act as a preventive for headache.

“Think of the headache you just had like you’ve run a marathon or done some other stressing activity,” Dr. Rizzoli says. “Your body needs to recover, which is not the same as staying in bed with the lights off. Ease up, but stay functional.”

Can an implanted tongue-stimulating device curb your sleep apnea?

Man asleep in bed, snoring, on his side; woman awake and looking at him with one hand cupped over her ear to block noise

Loud snoring, grunts, and gasps can be a sign of obstructive sleep apnea, a serious disorder that causes repeated, brief pauses in breathing (apneas) throughout the night. It can leave people drowsy and depressed, and put them at risk for high blood pressure, heart disease, and other health problems.

If this sounds like you or a bed partner, a recent spate of advertisements for a mask-free treatment for the disorder may catch your attention. Known medically as a hypoglossal nerve stimulator, the pacemaker-like device moves the tongue forward during sleep. That helps reopen a collapsed airway — the root cause of obstructive sleep apnea. But how does it compare with other treatments, and who might be a good candidate?

A second-choice therapy for sleep apnea

Marketed under the name Inspire, the device was approved by the FDA in 2014. It’s a second-choice therapy intended only for people who can’t tolerate positive airway pressure (known as PAP or CPAP), according to Dr. Rohit Budhiraja, a pulmonary and sleep specialist at Harvard-affiliated Brigham and Women’s Hospital.

“Sleep apnea causes the muscles in the back of the throat to collapse, which leads to pauses in breathing that wake you up again and again,” he says. PAP, the gold standard therapy for sleep apnea, prevents airway collapse by using a small bedside machine attached to tubing that blows air through a face mask.

This can improve a measurement called the apnea-hypoxia index (AHI) by approximately 90%, lowering it below 5 in most people. The AHI is a score that gauges the severity of sleep apnea. An AHI between 5 and 14 is considered mild; between 15 and 29 is moderate; 30 and higher is severe.

Targeting tongue muscles is less effective

Inspire targets only the muscles of the tongue rather than the entire airway, so it isn’t as effective as PAP. In fact, the company’s stated treatment goal is to lower a person’s AHI by just 50% (or below 20), although some people may do better.

Because PAP is more effective, sleep specialists encourage people to stick with it by trying different strategies. But research suggests a quarter to a third of people have a hard time using PAP (see here and here). When that’s the case, Inspire may be an alternative, says Dr. Budhiraja.

Who might consider hypoglossal nerve stimulation?

In addition to trying PAP without success, you also must

  • have moderate to severe sleep apnea (an AHI score of 15 to 65)
  • have a body mass index (BMI) of 32 or lower (although some centers allow BMI values as high as 35), which means the device is not right for people in some weight ranges.

If you meet these criteria, you can ask your doctor for a referral to a sleep specialist or an ear, nose, and throat surgeon. The next step is sleep endoscopy. While you are sedated, a doctor passes a small tube with a light and a tiny video camera on one end through a nostril to examine your upper airway. Up to a quarter of people have an airway collapse pattern that can’t be remedied with Inspire, Dr. Budhiraja notes. And, as noted, others have too high an AHI score to try it.

A surgical procedure requiring general anesthesia

The device is implanted during a short, same-day procedure done under general anesthesia. A generator is placed just below the collarbone, a breathing sensor at the side of the chest by the ribs, and a stimulation electrode around the hypoglossal nerve under the tongue.

As with all surgery, possible risks include bleeding and infection. Some people experience tongue weakness, which can cause slightly slurred speech and minor swallowing problems. But this usually resolves within a few days, or for most people, within a few weeks.

The device must be activated a month after surgery at a sleep laboratory. The breathing sensor monitors your breathing and, when necessary, it tells the generator to send a small electrical pulse to the electrode to make the tongue muscles contract. The stimulation moves your tongue forward so you can breathe normally.

How does it feel?

“Some people describe a mild tingling sensation, but most say the feeling is hard to describe,” says Dr. Budhiraja.

At home, you use a small remote control to turn the device on at night and off in the morning. The remote is set to gradually increase the level of stimulation once or twice a week as tolerated until you reach the highest level. You then return to the sleep lab for a study to determine your optimal range. The remote is then programmed to that range.

Some people start noticing a difference in their sleep quality even at the lowest levels of stimulation. Yearly checks are recommended thereafter, and the replaceable battery lasts about 11 years. Medicare and most major insurance plans cover Inspire.

Once it’s working, hypoglossal nerve stimulation is definitely convenient: no maintenance, cleaning, or buying supplies as required with a PAP machine. “But because Inspire is less effective, it’s not considered a replacement for PAP,” says Dr. Budhiraja.

Talking to your doctor about your LGBTQ+ sex life

photo of a woman doctor talking with a man patient sitting by a window, view is over patient's shoulder

Editor’s note: in honor of Pride Month, we’re re-publishing a 2019 post by Dr. Cecil Webster.

Generally speaking, discussing what happens in our bedrooms outside of the bedroom can be anxiety-provoking. Let’s try to make your doctor’s office an exception. Why is this important? People in the LGBTQ+ community contend not only with a full range of health needs, but also with environments that may lead to unique mental and physical health challenges. Whether or not you have come out in general, doing so with your doctor may prove critical in managing your health. Sexual experiences, with their impact on identity, varied emotional significance, and disease risk, are a keystone for helping your doctor understand how to personalize your healthcare.

Admittedly, talking about your intimate sexual experiences or your gender identity may feel uncomfortable. Many LGBTQ+ patients worry that their clinicians may not be knowledgeable about their needs, or that they’ll to have to educate them. Finding a LGBTQ+ adept doctor, preparing ahead of time for your next appointment, and courageously asking tough questions can give you and your health the best shot.

Finding a skilled clinician who is LGBTQ+ adept

Many large cities have healthcare institutions whose mission centers on care for LGBTQ+ peoples. However, these organizations may prove inaccessible to many for a variety of reasons. Regardless of your location, asking friends, family, or others to recommend a clinician may be a game changer. If your trans friend had a relatively painless experience visiting an area gynecologist, perhaps your Pap smear may go smoothly there as well. If your coworker has a psychiatrist who regularly asks him about his Grindr use, perhaps it may be easier to navigate your gay relationship questions with her.

Word of mouth is often an undervalued method of finding someone skilled and attentive to the needs of LGBTQ+ individuals. Online, many clinicians offer a short bio with their areas of expertise, and there are provider directories featuring trusted clinicians. Further, some doctors regularly write articles and give talks that may offer clues about desired knowledge. A simple Google search of your provider may yield a bounty.

Next, give your doctor or healthcare organization a call. Don’t be shy about requesting someone whose practice matches your specific needs. Your health information is protected, and generally, physicians hold your clinical privacy dear. Keep in mind that not all clinics will know or share whether or not your doctor is, for example, also a lesbian, but they may pair you with someone well suited to your request or point you in the right direction.

Preparing for your appointment

Let’s say you are nervous about coming out to your doctor. A little preparation may ease this burden. Here are some quick tips:

  • Let them know you’re nervous at the start of the conversation.
  • Be as bold as you can tolerate.
  • Write down what you are excited about, nervous about, and/or curious about.
  • Go in with a few goals and start with what’s most important.
  • Maximize your comfort. If your partner is calming, bring them. If Beyoncé soothes what ails you, bring her along too.
  • Lightly correct or update your clinician if they get something wrong.

Ask tough questions, give clear answers

As a psychiatrist who works with kids and adults, I often hear questions like, “I don’t know really how to say this, but I started experimenting with other guys. Does this mean I’m gay?” I may start by asking if you’ve enjoyed it. My colleagues in health care might begin with the same question.

Pleasurable experiences come in all sorts of constellations, and healthy exploration is part of being human. Additionally, clinicians need to assess and address your safety. Many LGBTQ+ people are at higher risk of intimate partner violence. We may ask about your use of condoms, how many partners you’ve had recently, your use of substances during sex, and how these experiences may shift how you see yourself. Give clear answers if possible, but don’t fret if you’re uncertain. Your doctor will not likely provide a label or pry unnecessarily. They may offer constructive information on the use of condoms, reasons to consider using PrEP (which can effectively prevent HIV), and places you can go for more guidance. Physicians enjoy giving personalized information so that you may make informed healthcare decisions.

There is no end to what is on people’s minds. Be bold. Will tucking reduce my sperm count? Maybe. Does binding my breasts come with risk? Likely. Was Shangela robbed of her RuPaul’s Drag Race: All Stars 3 crown? Utterly, but let’s get back to your cholesterol, shall we?

Remember that it is often impossible to squeeze everything into one appointment. Afterward, take time to catch your breath, reflect on what you’ve learned, and come up with more questions for next time. We’re here for that.

If cannabis becomes a problem: How to manage withdrawal

close-up photo of the hands of a young man rolling a joint

 

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.

An emerging treatment option for men on active surveillance

tightly cropped photo of a sheet of paper showing prostate cancer test results with a blood sample tube, stethoscope, and a pen all resting on top of it

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.”

Ring vaccination might help curtail monkeypox outbreaks

A red figure standing in a white circle connected to a white circle with a black figure, who is connected to circles with two other black figures; the concept of how infection spreads

By now, you’ve probably heard that there is a monkeypox outbreak traveling around the globe. Cases have spread far and wide, including in the US, Canada, Europe, and Australia. It’s the largest outbreak ever recorded outside of western and central Africa, where monkeypox is common.

But controlling this outbreak demands preventive measures, such as avoiding close contact with people who have the illness and vaccination. One method of vaccination, called ring vaccination, has worked well in the past to contain smallpox and Ebola outbreaks. It may be effective for monkeypox as well.

How can monkeypox be contained?

According to the Centers for Disease Control and Prevention (CDC) and the World Health Organization, monkeypox is unlikely to become a pandemic. At this time, the threat to the general public is not high. The focus is on identifying possible cases and containing the outbreak as soon as possible.

Three important steps can help stop this outbreak:

  1. Recognize early symptoms
  • Usually, early symptoms are flulike, including fever, fatigue, headache, and enlarged lymph nodes.
  • A rash appears a few days later, changing over a week or two from small flat spots to tiny blisters similar to chickenpox, then to larger, pus-filled blisters.
  • The rash often starts on the face and then appears on the palms, arms, legs, and other parts of the body. If monkeypox is spread by sexual contact, the rash may show up first on or near the genitals.
  1. Take steps to stop the spread
  • Monkeypox spreads through respiratory droplets or by contact with fluid from skin sores.
  •  Anyone who has been diagnosed with monkeypox, or who suspects they might have it, should avoid close contact with others. Once the sores scab over, the infected person is no longer contagious.
  • Health care workers and other caregivers should wear standard infection control gear, including gloves and a mask.
  • In the current outbreak, many cases began with sores in the genital and rectal areas among men who have sex with men, so doctors suspect sexual contact spread the infection. As a result, experts are encouraging abstinence when monkeypox is suspected or confirmed.
  1. Use vaccination to help break the chain
  • Monkeypox is closely related to smallpox. People who received a smallpox vaccine in the past may have some protection from monkeypox. (The US smallpox vaccination program was discontinued in 1972, and smallpox was declared eradicated worldwide in 1980.)
  • Stockpiled smallpox vaccinations and newer vaccines that can be used for monkeypox or smallpox are also available.

Ring vaccination

Monkeypox differs from the virus that causes COVID-19. People with monkeypox usually have symptoms when they’re contagious, and the number of infected persons is usually limited.

This means it’s possible to vaccinate a “ring” of people around them rather than vaccinating an entire population. This selective approach is called ring vaccination.

Ring vaccination has been used successfully to contain smallpox and Ebola outbreaks. It may come in handy for monkeypox as well. Here’s how it works:

  • As soon as a case of monkeypox is suspected or confirmed, the patient and their close contacts are interviewed to identify possible exposures.
  • Vaccination is offered to all close contacts.
  • Vaccination is also offered to those who had close contact with the infected person’s contacts.

Ideally, people should be vaccinated within four days of exposure.

This approach requires widespread awareness of monkeypox, rapid isolation of suspected cases, and an efficient contact tracing system. And of course, vaccines must be available whenever and wherever new cases arise.

Are the vaccines used for monkeypox effective?

According to the CDC, the smallpox vaccine is 85% effective against monkeypox.

While a newer vaccine (JYNNEOS) directed against monkeypox and smallpox has only been tested for effectiveness in animals, it is also expected to be highly effective in humans.

Of course, vaccinations can only work if people are willing to receive them. We’ll learn more about this as more people are offered the option for vaccination.

Are the vaccines used for monkeypox safe?

As with most vaccines, the most common side effects include

  • sore or itchy arm at the site of the injection
  • mild allergic reactions
  • mild fever or fatigue.

Fortunately, more severe side effects, such as significant allergic reactions, are rare.

The bottom line

In light of the current monkeypox outbreak, you may soon be hearing more about ring vaccination. Then again, if appropriate measures are taken to prevent its spread, this outbreak may soon be over. Either way, this won’t be the last time an unusual virus shows up seemingly out of the blue in unexpected places. Climate change, shrinking animal habitats, rising global animal trade, and increasing international travel mean that it’s only a matter of time before this happens again.

If climate change keeps you up at night, here’s how to cope

photo of a newspaper article warning of worsening climate change as the planet warms, shown outside against a blue sky and sun

A forest fire in northern California and a mile-long glacier breaking apart appear in your news feed. The stark reminders of climate change are constant, and may cause additional stress to your daily tasks. For example, in surveying your shopping cart filled with wipes, sandwich bags, and packets of baby food, you may question your choices, knowing that the plastic in those items will never break down completely. You may feel guilty about driving the short distance to the store, or you may struggle to stop worrying about how your actions will affect future generations.

What is climate anxiety?

Climate anxiety, or eco-anxiety, is distress related to worries about the effects of climate change. It is not a mental illness. Rather, it is anxiety rooted in uncertainty about the future and alerting us to the dangers of a changing climate. Climate change is a real threat, and therefore it's normal to experience worry and fear about the consequences. Anxiety about the climate is often accompanied by feelings of grief, anger, guilt, and shame, which in turn can affect mood, behavior, and thinking.

How common is climate anxiety?

According to a survey by the American Psychological Association, more than two-thirds of Americans experience some climate anxiety. A study published by The Lancet found that 84% of children and young adults ages 16 to 25 are at least moderately worried about climate change, and 59% are very or extremely worried. This makes sense, as children and young adults will disproportionately suffer the consequences of environmental changes. A 2021 UNICEF report estimates that one billion children will be at "extremely high risk" as a result of climate change. Children and young adults are also particularly vulnerable to the effects of chronic stress, and climate anxiety may affect their risk of developing depression, anxiety, and substance use disorders.

How does climate change affect mental health?

In addition to existential worries and fears about the future, climate change can affect mental health directly (such as through natural disasters or heat) and indirectly (through displacement, migration, and food insecurity). Rising temperatures have been associated with increases in emergency department visits for psychiatric reasons, and may impair cognitive development in children and adolescents. Furthermore, food insecurity is associated with depression, anxiety, and behavioral problems.

How can you manage climate anxiety?

As uncertainty and a loss of control characterize climate anxiety, the best treatment is to take action. On an individual level, it’s therapeutic to share your worries and fears with trusted friends, a therapist, or by joining a support group. You can also make changes to your lifestyle consistent with your values. This may include deciding to take fewer flights, joining a protest, or increasing public awareness about climate change through advocacy. Joining an organization like The Good Grief Network can help you process feelings related to climate anxiety and connect with others to take meaningful action.

How can you help a younger person?

Climate anxiety disproportionately affects children and youth. To be an ally for a child, adolescent, or younger adult with climate anxiety, you can consider showing your support in the following ways:

  • Validate their concerns. “I hear you, and it makes sense that you are worried (or angry) about this issue.”
  • Help direct their efforts to advocacy groups. Spend time together researching organizations that they can get involved with.
  • Educate yourselves on steps you both can take to minimize your impact on the environment.
  • Support your loved one’s decisions to make changes to their lifestyle, especially changes they can witness at home.
  • Spend time in nature with your family, or consider planting flowers or trees.

The bottom line

Climate anxiety is rife with uncertainty, but taking action may help you feel in control. Talk with others, join forces, and make lifestyle changes based on your values.

Poliovirus in wastewater: Should we be concerned?

The tip of a pink highlighter pen running over the word "Polio;" a few words from a definition of the illness are also shown

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.
