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.

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.

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.

A study asks whether people who eat a lot of fish have a higher risk for the skin cancer melanoma.

If you’re trying to stick to a healthy diet, fish is a good choice, right? After all, fish is high in protein, low in saturated fat, and a good source of omega-3 fatty acids, vitamin D, and many other nutrients. Eating more fish can mean eating less of foods with harmful fats and higher calorie counts. Indeed, nutritionists commonly recommend more seafood (and fewer cheeseburgers) to improve your diet, and nutrition guidelines promote fish as part of a healthy diet.

So, it seems surprising that a new study in Cancer Causes and Control suggests a link between eating fish and skin cancer, particularly since the biggest known risk factor for melanoma is not dietary ­–– it’s sun exposure. Having five or more sunburns in your life doubles your risk of developing melanoma.

A study links eating fish often with higher risk of melanoma

Melanoma, the most serious type of skin cancer, is responsible for more than 7,500 deaths in the US each year. And cases are on the rise.

In the new study, researchers found a higher risk of melanoma among people who ate the most fish. This study is among the largest and most well-designed to examine this link. Nearly 500,000 people in six US states completed a dietary questionnaire in 1995 or 1996. The average age of participants was 61 and 60% were male. More than 90% were white, 4% were Black, and 2% were Hispanic.

Over the following 15 years, the researchers tallied how many people developed melanoma, and found that:

• The rate of melanoma was 22% higher among people reporting eating the most fish (about 2.6 servings per week) compared with those who ate the least (0.2 servings a week, or about one serving every five weeks). Similar trends were noted for intake of tuna.
• The risk of precancerous skin changes (called melanoma in situ) rose similarly among those in the group that ate the most fish.
• Interestingly, researchers found no increased risk of melanoma among those eating the most fried fish. This is surprising because, if eating fish increases the risk of melanoma as the study suggests, it’s not clear why frying the fish would eliminate the risk.

Does this mean eating fish causes melanoma?

No, it doesn’t. It’s too soon to make definitive conclusions about the relationship between fish in our diets and melanoma. The study had important limitations, including

• Type of study. Observational studies like this one can detect a possible link between diet and cancer but cannot prove it.
• Reliance on self-reported survey data. People self-reported how many servings of fish they ate each week, which may not be accurate. Also, researchers assumed that fish consumption reported on the initial survey persisted for 15 years, which may not have been the case.
• Accounting for other factors. Many factors affect risk for melanoma, such as varied sun exposure depending on where participants lived. The analysis did account for some key factors, yet the study didn’t collect information about sun exposure, past sunburns, or use of sunscreen — all important in melanoma risk. Nor did researchers ask about skin type or number of moles; fair skin or higher numbers of moles raise risk for melanoma.
• Contaminants. Mercury or arsenic in fish may be to blame for its link to melanoma. This study did not record contaminants, but previous studies link mercury exposure with the risk of skin cancers, including melanoma.
• Lack of diversity. It’s not clear if the findings apply broadly to people in different racial and ethnic groups, because nine in 10 study participants were white.

Are some fish safer to eat than others?

The study did not explore this question. However, if contaminants like mercury in fish are responsible for increasing the risk of melanoma, the FDA offers advice on which fish are safer to eat, particularly for children and those who are pregnant or breastfeeding.

Yet even if fish is confirmed as a contributor to the risk of melanoma, other positive effects of fish consumption (such as cardiovascular benefit) may far outweigh this risk.

The bottom line

The researchers responsible for this study are not recommending a change in how much fish people eat. More study is required to confirm the findings, investigate which types of fish affect melanoma risk, and determine whether certain contaminants in fish are responsible for any added risk.

In the meantime, fish with lower mercury levels (such as salmon and clams) remain better dietary choices than the high-fat, highly processed foods typical of many Western diets.

If you’re planning to spend a lot of time outside this summer, limiting sun exposure and using sunscreen will likely have a bigger impact on skin health and your overall health than avoiding seafood.

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.

Inflammatory bowel disease (IBD) is commonly diagnosed when people are in their 20s and 30s, which is also when many people are planning families. Many people who have been diagnosed with IBD (which includes Crohn’s disease and ulcerative colitis) have questions and concerns regarding their fertility, conception, pregnancy, delivery, and breastfeeding.

Thinking about conceiving a child or becoming pregnant?

It is important to make sure that your IBD is well controlled, ideally before you begin trying to have a biological child. This is equally important for patients with male and female reproductive anatomy.

Patients with female reproductive anatomy who conceive in remission tend to remain in remission throughout their pregnancy. Research shows that poorly controlled IBD can lead to decreased fertility, and pregnancy can be complicated by premature loss, preterm labor, low birthweight, and small for gestational age babies.

You may require blood work, imaging, or endoscopy prior to conception to get an idea of whether you have an actively inflamed bowel before pregnancy. Your doctor may also modify your medications to ensure that your disease is as well controlled as possible.

You will require care from different types of health care providers during pregnancy, in addition to a gastroenterologist with expertise in IBD. Depending on the history and severity of your IBD, you may benefit from having a high-risk maternal fetal OB/GYN, colorectal surgeon, pharmacist, IBD nurse, psychologist, or nutritionist as part of your care team.

What should I do before I start trying to conceive or become pregnant?

It is recommended to take a prenatal vitamin and/or folic acid supplement. Vitamin D deficiency is common in IBD, and if your levels are low your doctor may recommend supplementation. It is also important to be up to date on your vaccines and review your medication list with your doctor.

Will I need to change my treatment before conception or pregnancy?

Many IBD medications have favorable safety profiles during conception and pregnancy. However, there are some medications that may impact fertility (such as by decreasing sperm count) or that may be unsafe to continue during pregnancy. For example, it is generally recommended to stop taking the drug methotrexate three months before conception.

As newer drugs are developed, research about the safety of IBD treatments continues. It is important to discuss your medications and any concerns you may have during the pregnancy planning period.

How will I be monitored during pregnancy?

Your gastroenterologist will carefully monitor your symptoms during preconception, pregnancy, and postpartum. You may be asked to provide stool samples to assess fecal calprotectin levels (a marker of inflammation measured in the stool), which can help your doctor monitor IBD activity prior to conception and during each trimester of your pregnancy.

Drug levels of certain IBD medications may be monitored via blood work as well, to ensure proper medication dosing. Monitoring and managing IBD throughout pregnancy is individualized for each patient, and the goal is to increase the chances of a healthy outcome for both you and your baby.

What if I have an IBD flare while pregnant?

During an IBD flare in pregnancy, the goal is to rapidly decrease inflammation and optimize an IBD treatment regimen in order to avoid complications for you and your and baby. This may involve drug level monitoring, adjusting medication dosage, or switching medication types. A short course of steroid medications may be needed in certain cases.

If your blood work indicates iron deficiency anemia (which can be caused by inflammation in the GI tract, but can also occur in pregnancy due to increased iron requirement for the baby), iron supplements, either oral or intravenous, can be used to improve blood counts.

What are my options for delivery?

Most people with IBD can deliver via their preferred method. The decision to have a vaginal or cesarean section delivery sometimes depends on a patient’s medical history. If a patient has Crohn’s disease and active perianal disease, a cesarean section may be recommended. This is because active perianal disease increases the risk of severe tears and trauma to the perineal area (area around the anus and vagina).

Patients with a history of steroid exposure and bone complications (like osteoporosis) may want to avoiding pushing during a vaginal delivery. A cesarean section may also be recommended if there are significant risk factors for injury to the perineal area, or an obstetric complication unrelated to Crohn’s or ulcerative colitis.

What happens after I give birth?

After delivery, it’s important to continue IBD medications. Approximately one-third patients will have an IBD flare within a year following delivery. Patients with poorly controlled IBD during the third trimester or while in de-escalation of therapy (reduction in medications) during or after pregnancy are at the highest risk for a postpartum flare. For this reason, it is important to maintain close follow-up with your IBD doctor during this time.

Can I breastfeed/chestfeed?

Breastfeeding/chestfeeding has many benefits for both the postpartum person and infant. Many IBD treatments have favorable safety profiles for breastfeeding/chestfeeding. Some newer biologic medications have not yet been studied well. Your doctor will discuss the risks and benefits of your individualized IBD treatment to ensure your regimen and breastfeeding goals are both optimized.

Will my baby have IBD?

While there is a genetic component to IBD, there is usually a low risk of IBD for biologic children of IBD patients. First-degree relatives (and in particular, siblings) of people with IBD do have an increased risk of Crohn’s disease and ulcerative colitis.

The bottom line

It is important to discuss family planning goals with your doctors early, so they can help you optimize your health and focus on achieving remission prior to conception. Fortunately, many IBD medications are considered safe and effective during conception, pregnancy, and postpartum. During pregnancy, proactive monitoring and early treatment of flares is essential. Every pregnancy is different, and close communication with your medical team is important to keep you and your developing baby healthy.

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.

More than five million Americans use wheelchairs. Getting one repaired is hard.

Wheelchairs restore mobility to people who are unable to walk or have limited ability to do so. Over a lifetime, this may describe many of us due to changes in health, injuries, neurological conditions, or disabling conditions like arthritis. So, when wheelchair technology or parts quit working, a quick fix would seem essential, right?

I know this firsthand. Unable to walk from decades with multiple sclerosis, I keep small scooters on every floor of my 1911 home, which is further adapted for accessibility with stair lifts and ramps. One day when I turned on my second-floor scooter-type wheelchair, sparks arced from the tiller opening atop the steering column, followed by smoke and the acrid smell of burning electrical wires. It was late on a Friday afternoon. No emergency repair service exists for wheelchairs or scooters. Now what?

Wheelchair repair delays are far more than an annoyance

Wheelchairs allow millions of Americans with mobility disability to participate in daily activities and community life (note: automatic download). We know this improves physical and mental well-being and overall quality of life.

On that Friday, my only option was to have my husband bring my first-floor scooter to the second floor. There I stayed, awaiting repairs on the now-inoperable scooter while my husband brought my meals upstairs. Because I have used the same small assistive technology company for more than 20 years — and have the owner’s cell phone number — by midafternoon on Tuesday, I once again had functional scooters on both floors. My confinement had lasted only four days. I know I was lucky on many levels.

But what if I lived alone, didn’t have another operational scooter, or hadn’t been able to wait four days? And what about people experiencing far longer waits for help with an essential device? While the 1990 Americans with Disabilities Act (ADA) prohibits discriminatory policies and requires physical accessibility in public services and spaces, it says nothing about this issue.

How often do wheelchairs break down?

Ideally, a wheelchair should be safe, reliable, and match your activity goals and functional needs. It should provide strong postural support and seating that protects against pressure injuries. Depending on strength and endurance, you might wish to self-propel a manual wheelchair. Or you might need a mobility scooter or power wheelchair propelled by a battery-powered motor, one that might even have sip-and-puff operational assistance or a chin-operated trackball.

Regardless of complexity, however — from basic manual wheelchairs to sophisticated rehab power chairs — all wheelchairs can break down, leaving their users stranded. Factors like broken pavement, inadequate curb cuts or soft terrain, steep inclines and inclement weather, and poor wheelchair design pretty much guarantee this.

In one study of 591 wheelchair users with spinal cord injury, 64% reported needing at least one wheelchair repair in the past six months. Among users requiring just one repair, wheels and casters posed the most difficulties for manual wheelchairs (46%). Electrical systems (29%) and power/control systems (27%) caused most problems for power wheelchair users. Rates of wheelchair breakdowns have increased in recent years, and vary across wheelchair manufacturers.

Repairs are costly, in more than one way. A survey of 533 wheelchair users with spinal cord injury found:

• Out-of-pocket repair costs ranged from $50 to $620 (the median, or midpoint, cost was $150).
• Time spent experiencing adverse consequences from wheelchair breakdown before repair ranged from two to 17 days (five days was the median).
• Among those reporting adverse consequences, 27% were stranded inside their home, 12% were stuck in bed, and 9% were stranded outside their home.

Wheelchair repair delays are lengthening: Could right to repair laws help?

Lengthening repair delays (automatic download) that heighten risks to consumers’ physical and mental health have caused many wheelchair users across the US to voice their outrage. However, reducing repair wait times isn’t simple. Medicare moved to competitive bidding in 2011, causing most small vendors — like my assistive technology company — to leave the business.

The two behemoths owned by private equity firms that now dominate the marketplace focus on boosting profits and cutting costs. By reducing technician hours and parts inventories, restricting consumers’ access to parts and software passcodes, requiring pre-approvals from insurers for repairs, and other practices, these companies virtually ensure delayed repairs.

Furthermore, Medicare and other insurers do not pay for preventive maintenance such as tightening loose bolts and cleaning casters, allowing problems to go undetected until breakdowns occur. Training can allow some wheelchair users to perform preventive maintenance tasks, but such training programs are not widely available.

Trying to reduce repair delays, Colorado’s governor recently signed the first “right to repair” law in the US for power wheelchair users. Complex software programs control many functions of power wheelchairs, and by holding this software as trade secrets, the manufacturers and large vendors have forced consumers needing repairs to use their services.

Much like recent right to repair laws for cars, the Colorado law mandates that power wheelchair owners and independent repair shops have access to the embedded software tools, parts, and other resources required to diagnose, maintain, or repair power wheelchairs. Other states, such as Massachusetts, may follow. Power wheelchair users in Massachusetts are testifying at public hearings about their repair horror stories to motivate the legislature to act.

Given the complexities of the wheelchair industry, it’s not clear whether right to repair laws will shorten repair times for power wheelchairs. Additionally, this law does not address manual wheelchairs or scooters like mine. Clearly, much more remains to be done to ensure timely wheelchair repairs. As wheelchair use surges, with growing numbers of baby boomers with mobility disability wanting to remain active in their communities, solving the wheelchair repair crisis is increasingly urgent.

At one time, replacement parts for the eyes must have seemed unimaginable. Nowadays, if the inner lens of the eye becomes clouded by a cataract, a routine surgery to swap it out with a new artificial lens restores vision.

But what happens if the outer lens of the eye (the cornea) becomes damaged or diseased? You can have that replaced, too. “It’s not as common as cataract surgery, but many people get corneal diseases after age 50 and may need a corneal transplant,” says Dr. Nandini Venkateswaran, a corneal and cataract surgeon at Harvard-affiliated Massachusetts Eye and Ear.

More than 49,000 corneal transplants occurred in 2021 in the US, according to the Eye Bank Association of America.

What is the cornea?

The cornea is a dome of clear tissue at the front of each eye, covering the iris and pupil, that acts as a windshield that protects the delicate eye apparatus behind it, and focuses light onto the retina, which sends signals that the brain turns into images (your vision).

You need this combo of windshield and camera lens to focus and see clearly. But many things can go wrong within the five layers of tissue that make up the cornea. That can make it hard to see and rob you of the ability to read, drive, work, and get through other activities in your day.

How does damage to the cornea occur?

It may stem from a number of causes:

• Injuries, such as a fall. “Falls are a big reason for people to come in with acute eye trauma. The cornea can be damaged easily if something pokes it,” Dr. Venkateswaran says.
• Previous eye surgeries. “Especially for adults who’ve had several eye surgeries — such as cataract and glaucoma surgeries — the inner layers of the cornea can become damaged and weakened with age,” she adds.
• Illness. Problems like severe corneal infections, or genetic conditions such as Fuchs’ endothelial dystrophy, can cause vision loss.

What are the options for treating corneal damage?

Cornea treatment depends on the type of problem you have and the extent of the damage. “It’s a stepwise approach. Sometimes wearing a specialty contact lens or using medications can decrease swelling or scarring in the cornea,” Dr. Venkateswaran says.

When damage can’t be repaired, surgeons can replace one or a few layers of the cornea (a partial-thickness transplant), or the whole thing (a full-thickness transplant).

The vast majority of transplants come from donor corneas that are obtained and processed by eye banks throughout the US. In some instances, such as when repeated transplants fail, an artificial cornea is an option. Recovery after corneal surgery can take up to a year.

How long-lasting are corneal transplants?

There’s always a risk that your body will reject a corneal transplant. It happens about a third of the time for full-thickness transplants. It occurs less often for partial-thickness transplants. Preventing rejection requires a lifetime of eye drops.

Still, transplant longevity varies. “I’ve seen transplants from 50 or 60 years ago and now they’re starting to show wear and tear. Other patients, for a variety of reasons — immune system attacks, intolerance to eye drops, or underlying conditions — may only have a transplant for five to 10 years before they need another,” Dr. Venkateswaran explains.

Preventive eye care can help preserve the cornea

It’s crucial to get regular comprehensive eye exams to make sure your corneas and the rest of your eyes are healthy.

The American Academy of Ophthalmology recommends a comprehensive (dilated) eye exam

• at age 40
• every two to four years for people ages 40 to 54
• every one to three years for people ages 55 to 64
• every one to two years for people ages 65 and older.

You’ll need an eye exam more often if you have underlying conditions that increase your risk for eye disease, such as diabetes or a family history of corneal disease.

If you have any vision problems, such as eye pain, redness, blurred vision despite new glasses, or failing eyesight, see an eye doctor.

Fortunately, for people who do experience corneal damage, advances in surgical options are encouraging.

“Corneal transplants are a miracle,” Dr. Venkateswaran says. “I have patients whose quality of life was significantly decreased because they couldn’t see through their cloudy windshield. We can give them sight again, and we have the technology and medications to keep the transplant alive.”

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.
