A visit with a surgeon can be overwhelming. You may feel anxious about your planned surgery. Many questions could be swirling in your head during a rushed visit. While surgeons have a reputation as technical specialists, bedside manner may be lacking at times.

It sounds simple, but setting the right expectations — on both sides — can ease your anxiety and help you feel more comfortable during a visit with your surgeon. So what exactly does this mean? And how can you accomplish it?

Tell your story

Tell your story to help set clear goals. Beyond simply stating what hurts or what is not working, be sure to include details such as

• how your current condition limits what you enjoy doing
• your daily activities
• how your condition affects your relationship with your social circle and family
• upcoming plans or goals such as travel, or life events like vacations or weddings.

Sharing details like these helps you collaborate to define a successful outcome for surgery.

Listen with your goals in mind

When explaining surgical options, surgeons are obligated to discuss key information, including risks, potential complications, and likely outcomes. Encourage your surgeon to put these facts into context based on what is important to you.

• Ask questions about how surgery will affect things you enjoy doing, such as playing pickleball, taking walks, cooking, reading, or listening to music.
• Ask what you should realistically expect during recovery and once you have recovered. For example, if you have a vacation or travel planned, be sure to discuss how surgery will affect your plans.

Define success before your surgery

Once you are confident that you have told your story and feel like you and your surgeon have set appropriate expectations, take the next step. Ask whether this discussion affects your surgeon’s approach to surgery, and explore how you each define surgical success.

Often, both surgeon and patient agree on a definition of success: for example, remove the entire tumor. But this simple definition may leave room for misalignment. Let’s say a surgeon is able to entirely remove a thyroid tumor, but now the patient speaks in a hoarse voice. While technically successful, this surgery may feel like a failure unless the person understood and accepted the risk that it could affect how they speak.

This highlights the importance of setting expectations. In this example, clear speech after surgery might be your expectation as a patient. Your surgeon must balance explaining how surgical risks might affect that expectation with the reality of treating the condition. Surgery is more likely to feel successful if both sides discuss and align their expectations.

Give yourself time when possible

Processing information about surgery can take time. A surgeon may have to provide realistic expectations that do not align with your initial expectations and hopes.

Some surgeries are urgent, others are not. If you do not need to make an immediate decision, be open with your surgeon. Let them know that you need time to consider the surgeon’s definition of success and your own. Reflecting on the discussion can reduce the stress and anxiety you’re likely to feel during an initial visit.

The bottom line: Making the most of your appointment

Communication goes two ways during a good pre-surgery visit. Do your best to tell your story and emphasize details of your life that are important. When listening, ensure that your surgeon acknowledges these details and describes how surgery may affect your life, as opposed to simply stating technical facts about the surgery. Setting expectations together will help you achieve a common goal and establish a strong surgeon-patient relationship that is essential for a positive surgical outcome.

We can feel groggy when our sleep schedule is thrown off even just a little. So what happens when shift work requires people to regularly stay awake through the night and sleep during the day — and how can they protect their health and well-being?

What is shift work disorder?

Mounting evidence, including several new studies, paints a worrisome picture of the potential health fallout of nontraditional shift work schedules that affect 15% to 30% of workers in the US and Europe, including factory and warehouse workers, police officers, nurses, and other first responders.

So-called shift work disorder mainly strikes people who work the overnight or early morning shift, or who rotate their shifts, says Eric Zhou, an assistant professor in the Division of Sleep Medicine at Harvard Medical School. It is characterized by significant problems falling and staying asleep, or sleeping when desired. That’s because shift work disrupts the body’s normal alignment with the 24-hour sleep-wake cycle called the circadian rhythm.

“People who work 9-to-5 shifts are typically awake when the sun is up, which is aligned with their body’s internal circadian clock. But for shift workers, their work hours and sleep hours are misaligned with the natural cues to be awake or asleep,” Zhou says. “They’re working against the universe’s natural inclinations — not just their body’s.”

What’s the connection between shift work and health?

A 2022 research review in the Journal of Clinical Sleep Medicine links shift work to higher risks for serious health problems, such as heart attack and diabetes. This research suggests adverse effects can include metabolic syndrome (a cluster of conditions that raises the risks for heart disease, diabetes, and stroke), accidents, and certain types of cancer.

“The research is consistent and powerful,” Zhou says. “Working and sleeping during hours misaligned with natural light for extended periods of time is not likely to be healthy for you.”

How do new studies on shift work boost our understanding?

New research continues to add to and strengthen earlier findings, teasing out specific health effects that could stem from shift work.

• Shift workers on rotating schedules eat more erratically and frequently than day workers, snack more at night, and consume fewer healthier foods with potentially more calories, a study published online in Advances in Nutrition suggests. This analysis reviewed 31 prior studies involving more than 18,000 participants, comparing workers’ average food intake over 24 hours.
• Disrupting the circadian rhythm through shift work appears to increase the odds of colorectal cancer, a malignancy with strong ties to lifestyle factors, according to a 2023 review of multiple studies published online in the Journal of Investigative Medicine. Contributors to this higher risk may include exposure to artificial light at night, along with complex genetic and hormonal interactions, study authors said.

“Cancer understandably scares people, and the World Health Organization recognizes that shift work is a probable carcinogen,” Zhou says. “The combination of chronically insufficient and poor-quality sleep is likely to get under the skin. That said, we don’t fully understand how this happens.”

How can you protect your sleep — and your health?

If you work overnight or early morning shifts, how can you ensure you sleep more soundly and restfully? Zhou offers these evidence-based tips.

Time your exposure to bright and dim light. Graveyard shift workers whose work schedule runs from midnight through 8 a.m., for example, should reduce their light exposure as much as possible after leaving work if they intend to go right to sleep once they return home. “These measures could take the form of wearing blue light–blocking glasses or using blackout shades in your bedroom,” he says.

Make enough time for sleep on days off. “This is often harder than it sounds, because you’ll want to see your family and friends during nonwork hours,” Zhou says. “You need to truly protect your opportunity for sleep.”

Maintain a consistent shift work schedule. “Also, try to minimize the consecutive number of days you spend working challenging shifts,” he says.

Talk to your employer. Perhaps your boss can schedule you for fewer overnight shifts. “You can also ask your doctor to make a case for you to be moved off these shifts or have more flexibility,” Zhou says.

Look for practical solutions that allow you to get more restful sleep. “People engaged in shift work usually have responsibilities to their job as well as their family members, who often operate under a more typical 9-to-5 schedule,” he notes. “The goal is to preserve as strong a circadian rhythm as possible under the abnormal schedule shift work requires.”

It used to be that doctors would automatically recommend treating all men with prostate cancer, even if their initial biopsies suggested the disease would grow slowly (or at all). But during the last several decades, the pendulum on treatment has swung the other way.

Doctors are now likely to advise active surveillance for low- to intermediate-risk cancers that may never turn deadly over the course of a man’s life. Active surveillance involves routine PSA checks, follow-up biopsies, and more recently, magnetic resonance imaging of a patient’s tumor. Treatment is initiated only when — or if — the disease shows signs of progression.

Recent evidence from Johns Hopkins University shows that the long-term risks of metastasis and death from low-grade prostate cancer among men on active surveillance averages just 0.1%. But doctors who care for such men also face a nagging question: which of their patients might have more aggressive cancer that should require closer monitoring? New findings published by the Johns Hopkins team in January provide useful insights.

The researchers’ approach

The researchers in this case zeroed in on the prognostic value of so-called perineural invasion, or PNI, on tumor biopsy samples. PNI simply means that cancer cells are moving into the perineural space between nerves in the prostate and their surrounding tissues. A finding of PNI raises red flags because the perineural space “provides a conduit by which tumor cells can potentially escape the prostate and grow elsewhere in the body,” says Dr. Christian Pavlovich, a urologic oncologist at Johns Hopkins who led the research.

Dr. Pavlovich’s team wanted to know if PNI detected on initial or follow-up biopsies would be associated with higher risks for cancer progression. So they analyzed long-term follow-up data from 1,969 men who had enrolled in an active surveillance research protocol at Johns Hopkins between 1995 and 2021. All the men were diagnosed initially with Grade Group 1 prostate cancer (the least risky form of the disease) and had undergone at least one follow-up biopsy since then.

What did the results show?

Among the 198 men with PNI, 44% of them (87 men in all) eventually progressed to Grade Group 2 prostate cancer, which is a more advanced form of the disease with an intermediate risk of further spread. Conversely, just 26% of the remaining 1,771 men without PNI (461 men) had progressed to Grade Group 2.

Pavlovich emphasizes that despite the new findings, PNI “does not make patients ineligible for active surveillance.” Importantly, the research showed that PNI was not associated with high-risk features, such as cancer in the lymph nodes of patients who wound up having surgery, or post-surgical elevations in PSA that show cancer still lurks in the body.

“What we’ve really shown here is that PNI puts men at a slightly higher risk of extraprostatic extension (cancer cells located just beyond the confines of the prostate),” Pavlovich says. “This is not necessarily a new finding. But PNI only occurs in about 10% of Grade Group 1 patients, and this is the boldest statement yet from the largest study conducted so far.” Pavlovich and his colleagues concluded that PNI provides an inexpensive and readily available indicator for identifying which men on active surveillance will benefit from more intensive monitoring protocols, including MRI and genetic tests.

Dr. Marc B. Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, agrees, while pointing out that PNI evaluations aren’t performed often enough. A PNI analysis of pathology specimens, he says, “along with emerging and sophisticated genetic testing of the tissue samples, may lead to more certainty in our recommendations to patients.”

Imagine this as a morning routine that replaces your first cup of coffee:

You wake up feeling a bit foggy, so you slip on a wearable device that looks like an extra-thick headband. You turn on the power source and settle in while electrical current flows into your brain. Twenty minutes later, feeling more focused and energized, you start your busy day feeling grateful for this new technology.

If this scenario sounds strange to you, I’m with you. And yet, hype around transcranial direct current stimulation (tDCS) is growing for an expanding list of conditions such as depression, ADHD, and even Alzheimer’s disease. A recent ad for one tDCS device urges you to “elevate your performance.” But before you give this a try, read on.

What is transcranial direct current stimulation?

Brain stimulation therapies aim to activate or inhibit parts of the brain. tDCS has been around for years, but its popularity has spiked over the last decade.

tDCS devices use headgear that may look like a swim cap or headband to position electrodes against the scalp. When a power source is switched on, the electrodes deliver low levels of electrical current to the brain. A typical session lasts 20 to 30 minutes and may be repeated over days or weeks.

Three better-known brain stimulation therapies are:

• Transcranial magnetic stimulation (TMS): A device worn over the forehead stimulates specific areas of the brain by changing nearby magnetic fields. TMS is cleared by the FDA to treat depression that hasn’t responded to standard medicines, and for obsessive-compulsive disorder.
• Electroconvulsive therapy (ECT): An electric current flowing through electrodes placed at specific locations on the scalp causes a brief seizure while a patient is under anesthesia. In use since the late 1930s, ECT can be highly effective for severe depression that hasn’t responded to standard therapies. It uses higher levels of electrical current than tDCS. That’s why it requires close medical supervision and is generally administered in a hospital or specialized clinic.
• Deep brain stimulation (DBS): Electrodes surgically implanted in specific areas of the brain generate electrical pulses. DBS is used to treat conditions such as Parkinson’s disease, epilepsy, or tremors that don’t improve with medicines.

What claims are made for tDCS?

The brain normally functions by sending and receiving tiny electrical signals between nerve cells. Stimulating specific regions of the brain with low levels of electricity might improve focus or memory, mood, or even dementia, according to tDCS advocates.

Some claims say tDCS can

• improve mental clarity, focus, and memory
• increase energy and motivation
• relieve so-called brain fog following COVID-19, Lyme disease, or other conditions
• reduce depression or anxiety
• reduce cravings among smokers or people with drug addiction
• improve symptoms of ADHD or Alzheimer’s disease.

Does tDCS work?

The jury is still out. Research suggests that tDCS holds promise for certain conditions, but techniques tested through research may differ from devices sold commercially for at-home use. For example, electrodes may be positioned more precisely over an area of the brain, and how current is delivered, session length, or number of sessions may differ.

Currently, small, short-term studies show that tDCS may benefit people with:

• Depression: An analysis of 10 randomized trials found some participants were more likely to report fewer symptoms of depression, or remission of depression, after a course of tDCS treatment compared with sham treatment.
• Alzheimer’s disease: A review of seven studies found that tDCS lasting 20 to 40 minutes improved memory and other cognitive measures in people with mild to moderate Alzheimer’s disease.
• ADHD: One randomized trial of 64 adults with ADHD found improved attention after 30 minutes of tDCS daily for a month.

The FDA has not cleared tDCS for any health condition, and it is considered investigational. More research with positive results and reassuring safety data are needed before tDCS gets a thumbs-up from regulators.

That’s probably why some ads for tDCS note in fine print that it is not a medical device and is only for recreational use.

Does tDCS have downsides?

While the FDA assesses tDCS as safe for adults, there are downsides to consider. For example, treatment may cause itching, irritation, or small burns at the sites of the electrodes. Some users complain of fatigue or headache.

There are no large, long-term studies of tDCS, so overall safety is uncertain. Some experts believe at-home use raises many questions, such as how much of the brain beyond targeted areas is affected, what inconsistent approaches to tDCS use might do, and how long changes in the brain — intended or not — could last.

Very limited research has been done in children. So, the consequences for a child’s developing brain aren’t clear.

Finally, tDCS devices can be expensive (several hundred dollars or more), and generally are not covered by health insurance.

The bottom line

It’s not yet clear how tDCS should be used, or who is most likely to benefit from it. If you’re interested in pursuing tDCS, understand that there’s still a lot we don’t know.

If you’re more skeptical and risk-averse (like me), you may want to wait for more definitive research regarding its benefits and risks — and for now, stick with your morning coffee to clear your mind.

Many people and their families associate the term palliative care with the end of life. Some may think that palliative care and hospice care are one and the same. So it’s worth explaining that palliative care is a medical specialty able to help people during many different stages of health, not just during a terminal illness. Importantly, the services offered could help you or someone you love enjoy a better quality of life, ease uncomfortable symptoms, and avoid unnecessary hospitalizations.

Asmedical oncologists (cancer doctors), we’ve witnessed how helpful this care can be when people experience cancer or another serious illness. Yet we find that not enough people who could benefit from this care receive it. By addressing misconceptions about what palliative care is and who it can help, we hope more people will ask for the full range of care they deserve, and inquire about whether a referral to palliative care is right for them.

What is palliative care?

Palliative care looks holistically at ways to improve quality of life for people and caregivers by

• helping people manage pain, nausea, fatigue, and other troubling symptoms associated with illness or treatment, to optimize their comfort and ability to function
• providing support for depression, anxiety, or stressors such as finances or relationships that may be affected by a serious illness
• improving care coordination by communicating with other health care providers to make sure everyone is on the same page regarding needs and preferences
• if appropriate, explaining and providing options for end-of-life care (this form of palliative care is part of hospice care).

In many health care settings, palliative care is handled by one or a few health care providers, such as a physician, physician assistant, or nurse practitioner. In others, palliative care may be provided by a team of clinicians and social workers, spiritual counselors, and case managers.

People sometimes think of palliative care as a last resort; you might have heard this, or even thought this way yourself. It may help to know that the type of care we’re describing is now recognized as essential to treatment, even during the early stages of serious illnesses like cancer, emphysema, heart failure, and kidney disease. People can and should receive palliative care while also receiving curative or life-prolonging treatments.

Who can palliative care help?

Palliative care can help any person experiencing a serious medical problem causing physical or emotional distress.

Typically, this refers to people with life-threatening or chronic illnesses such as cancer, heart disease, lung disease, neurologic impairment, or kidney failure. It can also refer to people who have experienced an injury resulting in physical ailments, emotional distress, or both. So in a sense, these services can be offered to anyone based on their symptoms rather than their specific diagnosis. Palliative care services are also available to support families and caregivers.

Why is my doctor talking to me about palliative care?

You might feel alarmed if your doctor recommends palliative care. However, it’s important to understand that the benefits of palliative care are greatest when introduced early after a new diagnosis of a serious illness, pain syndrome, or physical trauma. In our practice, we tend to explain the concept of palliative care soon after a cancer diagnosis for people who may benefit from additional support.

Our goal is to offer information on the resources available to support well-being, not to take away hope or scare people. The better you feel, the better you’ll do. Experiencing less pain, nausea, fatigue, or depression makes medical treatments and surgeries easier to tolerate, which may expand both quality and quantity of life.

We’ve answered frequently asked questions below.

Why is my doctor talking about palliative care?

To enhance support for people experiencing tough times and serious illnesses, not when “there’s nothing left to do.”

Am I dying?

A referral to palliative care does not mean that you are dying — it just means that you and your family may need more support to help you live as long and as well as possible.

Are you still my doctor?

Yes! Palliative care providers are consultants who team up with your doctors, including your primary care doctor and other specialists involved in your care.

If I have a question, who do I call?

If your question is related to a symptom or medicine managed by your palliative care team, then it is appropriate to reach out to them. However, you can never go wrong by calling the primary doctor directing your care, such as your oncologist if you have cancer. They can field your question and send you to the right person.

What medicines will be available to me?

Any medicines to help you feel better or live longer, including cancer treatments, are available if deemed helpful by you and your doctors.

Do I have to continue seeing my palliative care provider or team?

Just like any other doctor, they are available if you find you benefit from their services. If you no longer feel that you have needs that they can address, then you do not have to continue receiving their care.

Will my family benefit from palliative care?

Yes, definitely! One of the main goals of palliative care is to improve quality of life for people and their families or caregivers through counseling, information, and helping to coordinate doctor visits and medical tests.

The current shortage of semaglutide (Ozempic), an important diabetes drug, has an unusual origin: too many people without diabetes are taking it. Here’s how that happened, and how we might course-correct to help ensure that those with the greatest need for this medicine can get it.

A diabetes drug with an important side effect: Weight loss

Semaglutide (Ozempic) was first approved by the FDA in 2017 to help people with type 2 diabetes keep blood sugar under control. But during pre-approval studies, researchers noticed a remarkable side effect: people lost weight. For example, in one pivotal study, average losses for those receiving one milligram a week of semaglutide were:

• nearly 10 pounds lost over 30 weeks
• nearly 5% overall body weight lost
• waist size shrank 1.6 inches.

This side effect helped people with type 2 diabetes because excess weight is a major risk factor for the condition. Among other health benefits, weight loss can lower blood sugar and blood pressure, and reduce the need for other diabetes medications.

Turning a side effect into a selling point

Unintended weight loss would usually be listed as a side effect for a study medication. But ads for Ozempic didn’t list it with the other possible side effects; instead, it was featured as a benefit. The Ozempic “Tri-Zone” (a phrase concocted by marketers, not medical experts) promised improved blood sugar control, lower cardiovascular risk, and weight loss.

At the bottom of the ad, fine print that’s easy to miss states: “Ozempic is not a weight loss drug.” Talk about mixed messages!

The makers of Ozempic saw the potential of semaglutide as a weight loss drug for people without diabetes. Sure enough, clinical trials confirmed that overweight and obese people taking semaglutide also lost substantial weight. Semaglutide received FDA approval in 2021 for people with obesity (BMI of 30 or greater), or who were overweight (with a BMI of 27 to 29.9) and had a medical problem related to excess weight, such as high blood pressure or high cholesterol. As a weight loss drug, it was rebranded as Wegovy.

The only difference between the two drugs? The maximum approved dose of semaglutide is a bit higher with Wegovy than Ozempic.

How social media fueled the Ozempic shortage

Soon after the approval of Wegovy, celebrities and social media influencers began taking it and sharing glowing weight loss experiences. What’s more, medicines approved for specific uses in the US can be prescribed off-label for any use: up to 38% of all prescriptions written in the US are off-label (note: automatic PDF download). So, it’s likely some of the viral run on Wegovy was fueled by people who wanted to lose weight but had no medical reason to take it.

After high demand put Wegovy in short supply, many turned to Ozempic to lose weight. And that contributed to a shortage of Ozempic, threatening the health of people with type 2 diabetes who rely on the drug.

Readjust priorities and limit irresponsible prescribing

This situation couldn’t have happened without physicians or other health care professionals willing to write Ozempic prescriptions for people who did not have diabetes or another medical reason to use semaglutide. And that suggests an obvious solution: limit prescriptions for Ozempic to people with diabetes. For many drugs, a prior authorization process requires certain conditions be met before a prescription can be filled. This could be done for Ozempic.

And of course, we should encourage people who don’t have diabetes not to request a prescription for Ozempic. While that message is unlikely to show up in a drug ad, public service announcements could do the trick.

The bottom line

Drug ads often urge you to ask your doctor if a treatment is right for you. But we already know a key piece of the answer for Ozempic: if you don’t have diabetes, don’t ask for a diabetes medicine to help with weight loss. There are better ways to get the help you need to reach a healthy weight if you are overweight or obese. Talk to your doctor about a full range of treatment options. And if your weight is already in a healthy range, it’s not a good idea to take a medication to become thinner.

Finally, to keep vitally important medicines available for those who need them most, health care professionals must prescribe them responsibly. Responsible requests by their patients could help.

A simple word we all hear often — exercise — makes many people cringe. Unhappy childhood memories of school sports or gym classes, flat-out physical discomfort, guilty reluctance, or trouble finding time or pleasurable activities may help explain this. Additionally, for some people with obesity, fear of falling or injury is a high barrier to activity, recent research suggests.

That finding has important implications for health and well-being. So, how can we make movement safe and joyful for people of all weights?

Why be active?

As you may know, being physically active helps combat anxiety and depression. It prevents bone from thinning and tones muscle, helps you sleep better, lowers your blood pressure and blood sugar, and improves your cholesterol levels. It would take numerous medications to do all that routine physical activity can do for you.

Weight loss programs often incorporate exercise. Research shows that exercise helps with weight maintenance and may help with weight loss. Beyond burning calories, regular exercise also builds muscle mass. This matters because muscles are metabolically active, releasing proteins that play a role in decreasing appetite and food intake.

What does this study tell us?

The study found that many people with obesity fear injury and falling, which interferes with willingness to exercise. It followed 292 participants enrolled in an eight-week medical weight loss program in Sydney, Australia. All met criteria for obesity or severe obesity. The average age was 49; one-third of participants were male and two-thirds were female.

At the beginning of the study, participants filled out a 12-question injury perception survey. The majority reported fear of injury or falling, and believed their weight made injury more likely to occur. One-third said that their fear stopped them from exercising. The researchers also recorded weight, height, and waist circumference, and administered strength tests during the first, fourth, and last sessions.

When the study ended, the researchers found that the participants most concerned about getting injured hadn’t lost as much weight as those who did not express this fear. Those who hadn't lost as much weight also tended to have the highest scores of depression, anxiety, and sleepiness.

Fear of injury fuels a dangerous cycle

As noted, exercise is healthy at every weight: it protects your heart, lowers your blood sugar, boosts your mood, and tamps down anxiety. It also builds balance. Weight-bearing exercise such as walking prevents bone thinning.

If worries about injury or falls cause people to avoid exercise, they miss out on the balance-building, muscle-and-bone-strengthening, and mood-enhancing benefits of regular activity. They may be more likely to fall — and possibly more likely to experience fractures if they do.

Find a blend of activities that will work for you

Everyone, at every weight, needs to find ways to exercise safely, confidently, and joyfully.

• Start low and go slow. If you’re not currently active, start by simply sitting less and standing more. Try walking for two minutes every half hour. If you’re afraid of falling, try walking in place or alongside a friend or loved one who can provide security and comfort.
• Ask for guidance. Consider joining a YMCA where you can engage in supervised activities, or ask your doctor for a prescription to physical therapy to help you improve your balance and build your confidence.
• Try different activities to see what works for you. Walking is a simple, healthful activity, but it’s not the only form of activity you can try. You might enjoy swimming or water aerobics. Try pedaling a seated bike or an arm bike (upper body ergometer) that allows you to stay seated while you propel pedals with your arms instead of your feet. Adaptive activities and sports designed for people with physical limitations and disabilities are an option, too. Depending on your fitness level and interests, you might also consider dancing, biking, or anything else that gets you moving more often.

Lastly, keep in mind that many people suffer from anxiety, and a fear of falling is not insurmountable. If you’re really struggling, talk to your doctor or a mental health professional.

We all want our child to have friends. We want them to be happy, and to build the social skills and connections that will help them now and in the future.

Sometimes, and for some children, making friends isn’t easy. This is particularly true after the COVID-19 pandemic. Because of isolation and remote school, many children either didn’t learn the skills they need to make friends — or those skills got rusty.

Here are some ways parents can help.

Start at home: Learning relationship skills

Making and keeping friends involves skills that are best learned at home with your family. Some of them include:

• Empathy. Make sure that everyone in the family treats each other fairly and with kindness. Sometimes we turn a blind eye to sibling fights, or feel justified in snapping at our partner when we have had a long day. No matter what we say, our children pay attention to what we do.
• Curiosity about others. Make a family habit of asking each other about their day, their interests, their thoughts.
• Communication skills. These days, devices endanger the development of those skills. Shut off the devices. Have family dinners. Talk with each other.
• Cooperation. Do projects, play games, and do chores as a family. Work together. Help your child learn about taking turns and valuing the input of others.
• Regulating emotions. It’s normal to have strong feelings. When your child does, help them find ways to understand big emotions and manage them.
• Knowing when and how to apologize — and forgive. This really comes under empathy, but teach your child how to apologize for their mistakes, make amends, and forgive the mistakes of others.

All of these apply also to how you and your partner talk about — or with — other people in front of your children, too!

Be a good role model outside the home, too

When you are outside your home, be friendly! Strike up conversations, ask questions of people around you. Help your child learn confidence and strategies for talking to people they don’t know.

Make interactions easier

Conversations and interactions can be easier if they are organized around a common interest or activity. Here are some ways parents can help:

• Sign your child up for sports or other activities that involve their peers. Make sure it’s something they have at least some interest in doing.
• Get to know the parents of some of your child’s peers — and invite them all to an outing or meal. It could allow the children to get to know each other while taking some of the pressure off.
• When planning playdates, think about fun, cooperative activities — like baking cookies, or going to a park or museum.

Keep an eye on your child — but don’t hover

Ultimately, your child needs to learn to do this — and you don’t want to embarrass them, either. The two exceptions might be:

• If the children aren’t interacting at all, you might want to suggest some options for activities. Facilitate as necessary, and step back out again.
• If there is fighting or meanness on either side, you should step in and make it clear that such behavior isn’t okay.

Keep an open line of communication, and be supportive

Talk with your child regularly about their day, about their interactions, and how things made them feel. Listen more than you talk. Be positive and supportive. Remember that part of being supportive is understanding your child’s personality and seeing the world from their eyes. You can’t make your child someone they are not.

If your child keeps struggling with making friends, talk to your doctor

All parents need help sometimes — and sometimes there is more to the problem than meets the eye. This is particularly true if your child has ADHD or another diagnosis that could make interactions more challenging.

Many health-conscious consumers have already cut back on hamburgers, steaks, and deli meats, often by swapping in poultry or seafood. Those protein sources are better than beef, and not just because they’re linked to a lower risk of heart disease, diabetes, and cancer. Chicken and fish are also better for the environment, as their production uses less land and other resources and generates fewer greenhouse gas emissions.

And choosing seafood that’s lower on the food chain — namely, small fish such as herring and sardines and bivalves such as clams and oysters — can amp up those benefits. “It’s much better for your health and the environment when you replace terrestrial food sources — especially red meat — with aquatic food sources,” says Christopher Golden, assistant professor of nutrition and planetary health at the Harvard T.H. Chan School of Public Health. But instead of popular seafood choices such as farmed salmon or canned tuna, consider mackerel or sardines, he suggests.

Why eat small fish?

Anchovies, herring, mackerel, and sardines are all excellent sources of protein, micronutrients like iron, zinc, and vitamin B12, and heart-healthy omega-3 fatty acids, which may help ease inflammation within the body and promote a better balance of blood lipids. And because you often eat the entire fish (including the tiny bones), small fish are also rich in calcium and vitamin D, says Golden. (Mackerel is an exception: cooked mackerel bones are too sharp or tough to eat, although canned mackerel bones are fine to eat).

Small fish are also less likely to contain contaminants such as mercury and polychlorinated biphenyls (PCBs) compared with large species like tuna and swordfish. Those and other large fish feed on smaller fish, which concentrates the toxins.

It’s also more environmentally friendly to eat small fish directly instead of using them to make fish meal, which is often fed to farmed salmon, pork, and poultry. Feed for those animals also includes grains that require land, water, pesticides, and energy to produce, just as grain fed to cattle does, Golden points out. The good news is that increasingly, salmon farming has begun using less fish meal, and some companies have created highly nutritious feeds that don’t require fish meal at all.

Small fish in the Mediterranean diet

The traditional Mediterranean diet, widely considered the best diet for heart health, highlights small fish such as fresh sardines and anchovies, says Golden. Canned versions of these species, which are widely available and less expensive than fresh, are a good option. However, most canned anchovies are salt-cured and therefore high in sodium, which can raise blood pressure.

Sardines packed in water or olive oil can be

• served on crackers or crusty, toasted bread with a squeeze of lemon
• prepared like tuna salad for a sandwich filling
• added to a Greek salad
• tossed with pasta, either added to tomato sauce or with lemon, capers, and red pepper flakes.

Golden is particularly fond of pickled herring, which you can often find in jars in supermarkets, or even make yourself; here’s his favorite recipe.

Bivalve benefits

Bivalves are two-shelled aquatic creatures that include clams, oysters, mussels, and scallops. Also known as mollusks, they’re good sources of protein but are quite low in fat, so they aren’t as rich in omega-3’s as small, fatty fish. However, bivalves contain several micronutrients, especially zinc and vitamin B12. Zinc contributes to a healthy immune system, and vitamin B12 helps form red blood cells that carry oxygen and keep nerves throughout the body healthy. While most Americans get enough B12, some may not.

And from a planetary health perspective, bivalves are among the best sources of animal-based protein. “Bivalves can be ‘nature positive’ because they don’t require feed and they filter and clean up water,” says Golden.

Be aware, however, that bivalves can become contaminated from runoff, bacteria, viruses, or chemicals in the water. So be sure to follow FDA advice about buying and preparing seafood safely.

Although we tend to think of coastal cities as the best places to find seafood, it’s available throughout the United States. For less-common varieties, try larger Asian markets, which often carry a wide variety of fish and bivalves, Golden suggests.

Aquatic plant foods

You can even go one step further down the aquatic food chain by eating aquatic plant foods such as seaweed and kelp. If you like sushi, you’ve probably had nori, the flat sheets of seaweed used to make sushi rolls. You can also find seaweed snacks in Asian and many mainstream grocery stores. The truly adventurous may want to try kelp jerky or a kelp burger, both sold online.

Nutrients in seaweed vary quite a bit, depending on species (kelp is one type of brown seaweed; there are also numerous green and red species). But seaweed is low in calories, is a good source of fiber, and also contains iodine, a mineral required to make thyroid hormones. Similar to terrestrial vegetables, seaweeds contain a range of other minerals and vitamins. For now, aquatic plant foods remain fringe products here in the United States, but they may become more mainstream in the future, according to Golden.

Proton-pump inhibitors (PPIs) are a common type of anti-acid medication, and are available both by prescription and over the counter. Omeprazole and pantoprazole are examples of PPIs. They are the treatment of choice for several gastrointestinal disorders, such as peptic ulcer disease, esophagitis, gastroesophageal reflux disease, and H. pylori infection.

New guidelines by the American Gastroenterological Association have highlighted the need to address appropriate PPI usage, and they recommend that PPIs should be taken at the lowest dose and shortest duration for the condition being treated. However, PPIs are frequently overused, and may be taken for longer than necessary. This can happen unintentionally; for example, if the medication was started while the patient was hospitalized, or it was started as a trial to see if a patient’s symptoms would improve and then is continued beyond the needed timeframe.

Who should use PPIs in the short term?

There are a variety of reasons for short-term PPI usage. For instance, PPIs are prescribed typically for one to two weeks to treat H. pylori infection, in addition to antibiotics. A PPI course of four to 12 weeks may be prescribed for people with ulcers in their stomach or small intestine, or for inflammation in the esophagus.

People may also be prescribed a short course of PPIs for acid reflux or abdominal pain symptoms (dyspepsia), and for symptom relief while physicians perform tests to determine the cause of abdominal pain. People may be able to move to a lower dose of PPIs, or discontinue their medication altogether, if their symptoms get better or they have completed their treatment course.

Who should be on PPIs long-term?

Some patients with specific conditions may need to be on PPIs for the long term, and they should discuss their condition and unique treatment plan with their doctor. Some conditions that may require longer-term use of PPIs include:

• severe esophagitis, eosinophilic esophagitis, Barrett’s esophagus, esophageal strictures, or idiopathic pulmonary fibrosis
• acid reflux
• dyspepsia or upper airway symptoms that improve with PPI usage but worsen when stopping PPIs
• people with a history of upper gastrointestinal bleeding from gastric and duodenal peptic ulcers may need to be on PPIs long-term to prevent recurrence.

What are some side effects of PPIs?

Any medication can cause side effects. Fortunately, adverse effects from PPIs are generally rare. However, these medications have been associated with increased risk of certain infections (such as pneumonia and C. difficile). Previously, there had been concerns that PPI usage was linked to dementia, but newer studies have contradicted this association.

Additionally, while rare, PPIs may also cause drug interactions with other medications. For example, PPIs may affect the levels and potency of certain medications, such as clopidogrel (Plavix), warfarin (Coumadin), and some seizure and HIV medications, sometimes necessitating dosage adjustments of these drugs. Therefore, it is important to let the team of healthcare providers who manage your medications know when a new medication has been added to your list or if a medication has been discontinued.

How do I work with my doctor to step down from taking PPIs?

Some patients are prescribed PPIs twice a day in an acute situation, such as to prevent rebleeding from stomach ulcers or if a patient has severe acid reflux symptoms. If there no longer remains a reason to take PPIs twice a day, you may be stepped down to once a day. To discontinue a PPI, your doctor may decide to taper the medication — for example, by decreasing the dose by 50% each week until discontinued.

What might I experience if my doctor suggests I stop taking a PPI?

Studies have shown that for patients with long-term PPI use, there can be rebound secretion of stomach acid and an increase in upper gastrointestinal symptoms when discontinuing PPIs. However, a different type of anti-acid medication (such as an H2 antagonist like famotidine or a contact antacid medication containing calcium carbonate like TUMS) can be used for relief temporarily. If a patient experiences more than two months of severe persistent symptoms after discontinuing a PPI, this may be a reason to resume PPI therapy.

What steps should I take next?

It is important to routinely discuss your medication list and concerns with your primary care doctor. The decision to step down or discontinue a PPI is complex, and for your safety you should verify with your doctor before adjusting your PPI dosing. Ultimately, the goal is to make sure you are only taking medications that are necessary in order to maximize the benefit and minimize side effects.
