Ways Peripheral Artery Disease Can Affect Your Work
A few years ago, Dale Smith was unable to walk more than 10 or 15 paces at work before leg and toe pain forced her to sit and rest. As assistant manager of a grocery store in Beebe, AR, that was a big problem. “I have to constantly be on the floor walking,” says Smith, now 61.
Following a visit to her cardiologist, after she had a heart attack a year earlier, Smith learned she had peripheral artery disease (PAD), a narrowing of the arteries that mainly occurs in the legs. She had an angioplasty procedure done in a leg artery and began taking medication for pain and cholesterol.
Recently, Smith’s smartwatch told her she walked 15,000 steps pain-free, and she has kept a job she loves.
“I’m thankful I have a really great boss who understood fully and told me to take as many rest breaks as I needed,” she says. “But I did worry before if I could keep working.”
If you are diagnosed with PAD, your doctor hits you with a lot of information about exercise plans, diet, and medication. Making PAD treatment fit with your job may get less discussion. Even though PAD usually affects people in their 50s or older, that can leave a decade or more of working years to consider for people like Dale Smith.
“PAD is all about lifestyle adjustments, and work is a major part of everyone’s life,” says Damon Pierce, MD, a vascular surgeon for Virginia Mason Franciscan Health in greater Seattle.
Pierce had a PAD patient, an auto mechanic, who worked for 20 years in a shop with bonuses based on job speed. Over time, competing against younger mechanics in physically strenuous work that required him to get into and out tight spaces under cars, the mechanic’s PAD-related leg cramps worsened. But he was able to negotiate a workload that was less physically intense. Still, continuing job stress eventually led him to quit for a supervisory role in a new shop with a less demanding pace.
Typical PAD symptoms — pain or cramps in the legs, hips, or buttocks; trouble walking; sores or ulcers on the legs or feet that don’t heal — are not always severe enough to require a change of job. But discomfort can affect productivity. It’s smart to initiate adjustments that help keep you comfortable and pain-free.
Make sure that your work life fits with the treatment plan your doctor provides. You may need to ask your employer to make accommodations.
To help you manage your PAD on the job, here are several doctors’ recommendations:
Make time for exercise. A 10-minute walk isn’t the kind of exercise that helps manage your PAD. Instead, combine part of your lunch hour with other break time that allows an hourlong, vigorous and beneficial walk, Pierce suggests.
Take mental health breaks. Job-related stress raises the risk of hospitalization for PAD, one study found. Also, “when you’re stressed, you feel more tired and are less likely to do the exercise that improves blood flow through your legs,” says Amy Pollak, MD, a cardiologist with the Mayo Clinic Florida in Jacksonville and a volunteer advocate for the American Heart Association.
That’s why Pierce recommends taking mental breaks during the workday to relieve stress. Use that time to meditate or just walk around the building. Even a couple of minutes away from the job helps.
Stay warm. Colder temperatures interfere with blood flow to your legs and arms. Dress to stay warm at work, outdoors or indoors. And don’t be shy about asking to bump up the office thermostat.
Pay attention to your diet. If you eat lunch out, look for low-fat, low-salt choices on restaurant menus. If your building’s cafeteria is short on heart-healthy foods, ask if they could add some.
Think about air quality. Avoid areas where co-workers gather for smoke breaks. And avoid prolonged exposure to work environments where the air quality is poor.
Invest in good footwear. If your job requires a lot of walking or driving, you should buy comfortable, durable shoes with sturdy soles.
You may not want to change jobs just because you are managing PAD. But that doesn’t mean you should keep quiet and pretend nothing has changed.
“You want to be honest with your employer about what is going on, that you are following a prescribed treatment plan,” Pierce says.
He often writes a letter for his patients with PAD to give to their supervisors that explains what treatment involves and how they can stay productive with the company’s help.
You may need to ask for flexibility to balance your job with your PAD treatment. Here are a few possible scenarios:
- Request a change of duties if your job involves bursts of strenuous physical activity or requires heavy lifting. Sitting at a desk for hours at a time usually doesn’t increase risk unless your PAD is advanced, according to Pierce.
- Work additional hours or request deadline extensions if PAD is tiring you. “You need to be honest if it will take you longer to get a task done,” Pollak says
- Request time off for doctor’s appointments at varying times.
You may be nervous about asking your boss for flexibility. But remember you may have a legal right to ask for reasonable accommodations if your doctor certifies your PAD has become a disability. The federal Americans with Disabilities Act provides that right if your company employs 15 or more people and PAD “substantially limits” your ability to perform your duties in the current setting.
Despite your best efforts, it’s possible PAD symptoms could force you to take time away from work. Using your paid vacation and authorized sick days will be your first option.
But what if you have already burned through those days for this year?
Remember that under the federal Family and Medical Leave Act (FMLA), you can request up to 12 weeks a year of unpaid leave. You need to have worked for at least a year at a business that employs 50 or more people to qualify.
You can’t be fired or denied your old job for taking unpaid medical leave. And the company can’t stop paying its share of your health insurance. Even so, it’s recommended that you give your employer at least 30 days’ notice if you can and explain exactly why you need leave. You will have to provide a letter from your doctor if your employer requests one.
It is possible for PAD-related leg pain to get so bad that you are unable to keep working. In its online Blue Book manual, the Social Security Administration recognizes PAD as a “cardiovascular impairment” and potential disability. This means you may qualify for disability benefits to help cover your living expenses.
But just saying you deal with pain or labored walking from PAD will not be enough to get these benefits. You will need to see a doctor to get imaging tests on your blood vessels and blood pressure readings from your ankles or toes and then provide the results. You may want to hire an attorney who specializes in disability requests.
Pain and discomfort from PAD can create challenges for your work life. But there are approaches that help you enjoy a rewarding career as you manage PAD. Be assertive about making improvements to your job conditions, and don’t be shy about asking for help. You deserve to feel rewarded by your work life.
May 10, 2024 – When we’re young, we take our macula for granted. At the center of our retina – the deepest layer of the eye that’s chock-full of photoreceptors and that confers color to our world – the macula is like a high-resolution camera. As light hits our eyes, the retina’s macula recasts our world in a bloom of color with astoundingly high visual sharpness.
But as you age, your vision dulls. What once stood out sharply becomes foggy, like condensation on a windowpane. After some time, a coal-black smudge or cloudy circular area begins to affect your central vision.
This effective blind spot widens over time if left untreated. What remains is a “macular hole” in the center of your retina.
This unfortunate series of events marks the advanced stage of age-related macular degeneration, a dangerous retinal disease that affects about 20 million people in the U.S., and nearly 200 million people worldwide.
And it’s not getting better. Estimates are that by 2040, the disease may affect nearly 300 million people worldwide. We are very limited in our ability to treat or prevent it. Read on for what to know.
First, What Causes Age-Related Macular Degeneration?
AMD’s causes are varied, and whether it will affect you is mostly determined by age and genetics, said Marco Alejandro Gonzalez, MD, an ophthalmologist and vitreoretinal specialist in Delray Beach, FL.
Because of the different cocktails that we have in terms of our genetic makeup, some people’s photoreceptor cells in the macula “basically start to shut down,” he said.
AMD’s development involves over 30 genes, and if you have a first-degree relative – parent, sibling, child – who has the disease, you’re three times more likely to get it, too.
Gonzalez explained how the expected rise to 300 million cases by 2040 is due mostly to improved diagnostic tools, along with the fact that the world is getting older and living longer. (Usually, an optometrist can detect signs of AMD during a routine eye exam.)
Eye experts still struggle to stop AMD’s most harmful sign – the cause of those muddy, milky, or even coal-colored circles in your central vision: geographic atrophy.
Geographic atrophy can occur in either of the two forms of age-related AMD: “dry” AMD and “wet” AMD.
Nearly every case of AMD begins as the dry kind, affecting 80% to 90% of AMD patients.
Retinal disease expert Tiarnán Keenan, MD, PhD, offered a vivid image of geographic atrophy for those who have dry AMD.
“As time passes, the circular patches of GA expand like a brushfire, taking more and more vision with it, often to the point of legal blindness,” he said.
A researcher in the Division of Epidemiology and Clinical Applications at the National Eye Institute, Keenan recently led a study that tested the efficacy of the antibiotic minocycline in slowing geographic atrophy expansion in dry AMD. The study operated on the grounds that the body’s immune system could be at play in developing the disease.
When your body’s immune system is overactive, microglial cells (central nervous system immune cells) can get into the sub-retinal space and possibly eat away at the macula and its sensitive photoreceptors.
Though minocycline had been shown to reduce inflammation and microglial activity in the eye in diabetic retinopathy, it didn’t slow the expansion of geographic atrophy or vision loss in patients with dry AMD during Keenan’s study.
When asked if microglial activity could have very little to do with the atrophy expansion, Keenan said it’s something to consider: “Maybe microglia are just there as bystanders clearing up the debris … so inhibiting them is less likely to slow down progression.”
In future drug trials, “maybe it’s possible the minocycline or another approach to target microglia would be helpful, but it would be needed in combination with some other therapy and be ineffective by itself,” he said.
Two Sides of the Same Disease
In dry AMD, Gonzalez compares macular degeneration to the loss of pixels on a screen. “Some of those pixels burn out … and that’s the way you lose vision classically in the dry form.”
Wet AMD is a more progressive form of the disease. It causes abrupt vision loss due to abnormal blood vessel growth.
“If you don’t treat wet AMD quickly, it’s game over,” warned Gonzalez. “Wet macular degeneration is the quicker process of vision loss because these blood vessels wreak havoc.” These new blood vessels bleed, causing fluid to build in the macula, which ultimately leads to scarring.
Gonzalez shed light on why wet AMD develops. “The wet form, for some reason, is the body’s last-ditch effort to try to kind of ‘help’ a dying macula. … When these blood vessels start to grow under the retina, they quickly destroy the architecture of the macula.”
Stopping the Bleeding in Wet AMD
Though wet AMD is rarer, it’s more treatable than dry AMD. Signs and symptoms can be eased with various therapies injected into the eye.
Putting it simply, Gonzalez said these therapies to treat wet AMD “all basically do the same thing. They make these new blood vessels regress temporarily before they cause damage to the macula.”
The injected medication clears away those blood vessels and restores the architecture of the macula. People can recover some vision in this way, but it’s only a temporary tune-up, and shots must be given as often as once a month.
“Degeneration of the cells is still the main problem. You’re not stopping that. But degeneration itself is a lot slower than actual vision loss associated with these blood vessels.”
The Struggle in Developing New Treatments
According to Keenan, “nobody has been able to stop geographic atrophy from happening” in either form of AMD. “So, that’s the main work in the field with trials.”
In December 2023, the FDA approved two new drugs: Syfovre and Izervay, both of which only slow geographic atrophy. Degeneration still happens, regardless.
Keenan explained how these two new drugs are “complement inhibitors … given by injection into the eye once a month or so.”
“Complement” refers to the body’s complement pathway, a trigger that activates a cascade of proteins in enhancing immune response.
Clinical trials showed Syfovre slowing the rate of geographic atrophy by up to 22% over 2 years, and Izervay up to 14% over 1 year.
Though these drugs are a new weapon against this troublesome affliction, they aren’t without their complications.
“Anytime you give an injection in the eye, there’s always the risk of an infection because you’re introducing something from the outside. So that’s the biggest risk,” explained Gonzalez.
An infection is uncommon, but potentially devastating, as you can lose your eye altogether. There’s also the chance of a damaging reaction to the shot.
“You have to pick and choose your patients,” said Gonzalez. “Not everybody is a good candidate for those new shots … and the patient is never going to see better. … It’s a harder sell than the ones for wet AMD.”
A Common Protective Measure
Keenan and Gonzalez both have a fair degree of confidence in reducing the risk of AMD with vitamin therapy.
As a bit of background on how vitamins were found to act as a sort of preventive measure, Gonzalez said, “In the early and late ‘90s, there were series of studies which were called the age-related eye disease studies.” These are now referred to as AREDS 1 and AREDS 2.
Researchers proved that a certain cocktail of vitamins slowed down degeneration. The most is a combo of antioxidants: vitamins C and E and lutein and zeaxanthin, all of which are in the AREDS 2 formula.
People who took these vitamins had a lower chance of losing their vision over the next 2 to 5 years. “[The combo] seems to be complementary and additive … with a combined treatment effect of 55% to 60%, an excellent safety record, and very low cost,” Keenan said.
Gonzalez recommends the AREDS 2 formula of vitamins to every patient of his. “It’s such an easy thing to take, and the downside is minimal.”
Unfortunately, if your genes make you more likely to have the condition, a change in diet or vitamin use could have no effect.
Dire? Possibly. But not all is lost in this fight.
Vigilance with AMD and What to Do Next if You’re Diagnosed
Gonzalez is adamant in educating his patients before time has run out on treating AMD. Recognition is key. “The most common reason a lot of these people get to me ‘too late’ is they don’t realize there’s a problem.”
He explained a typical scenario: “Let’s say you have macular degeneration in both eyes at different stages. One of your eyes starts developing wet macular degeneration … so the better eye takes over and you may not notice there’s a problem.”
Even after a patient is diagnosed with AMD, they usually see a specialist only twice a year. Gonzalez often tells his patients to cover one of their eyes to make sure their vision is intact in both eyes. “You’ll be able to pick up on subtle differences” in each eye, he said.
This type of self-care and vigilance can be the difference between successfully living with and treating the disease for the rest of your life, and trying to get help when it’s simply too late.
For wet AMD, as mentioned before, a round of injections is basically what everyone does. Without quick, invasive treatment, the point of no return approaches rapidly.
May 16, 2024 – Multiple U.S. agencies are working to contain the recent bird flu outbreak among cattle to prevent further spread to humans (beyond one case reported in early April) and use what we learned before, during, and after the COVID-19 pandemic to keep farm workers and the general public safe.
Fingers crossed, the bird flu will be contained and peter out. Or the outbreak could continue to spread among dairy cattle and other animals, threatening the health and livelihoods of farmers and others who work with livestock.
Or the virus could change in a way that makes it easier to infect and spread among people. If this happens, the worst-case scenario could be a new influenza pandemic.
With so many unknowns, WebMD brought together experts from four federal agencies to talk prevention, monitoring, and what the “what ifs” of bird flu might look like.
Communication with the public “about what we know, what we don’t know, and ways you and your family can stay safe is a priority for us at CDC,” said Nirav D. Shah, MD, JD, the CDC’s principal deputy director. “We at the federal level are responding, and we want the public to be following along.”
People should consult the websites for the CDC, FDA, U.S. Department of Agriculture (USDA), and the Administration for Strategic Preparedness and Response (ASPR) for updates.
It is essential to not only stay informed, but to seek trusted sources of information, Shah said during “Bird Flu 2024 – What You Need to Know,” an online briefing jointly sponsored by the CDC and WebMD.
An ‘Experimental Hamburger’
If one take-home message emerged from the event, it was that the threat to the general public remains low.
The retail milk supply is safe, although consuming raw or unpasteurized milk is not recommended. “While commercial milk supply is safe, we strongly advise against drinking raw milk,” said Donald A. Prater, DVM, acting director for the FDA’s Center for Food Safety and Applied Nutrition.
As for other foods, thoroughly cooked eggs are less risky than raw eggs, and the nation’s beef supply remains free of the virus as well.
For years, federal inspectors have purchased and tested meat at retail stores, said Eric Deeble, DVM, USDA deputy assistant secretary for the Office of Congressional Relations. So far, H5N1, the virus behind bird flu, has not been detected in beef.
The USDA took testing a step further and recently cooked ground beef from dairy cows in their lab. Using what Deeble described as an “experimental hamburger,” the agency showed cooking beef to 165 F or higher kills the virus if it ever becomes necessary.
The federal government now requires all cattle be tested and be free of bird flu virus before crossing any state lines. The government is also reimbursing farmers for veterinary care and loss of business related to the outbreak, and supply personal protective equipment (PPE) like gloves, masks, and face shields to workers.
Vaccination Not Recommended Now
Federal scientists know enough about H5N1 virus to create vaccines against it quickly if the need arises. It’s more about planning ahead at this point. “Vaccines are not part of our response right now,” said David Boucher, PhD, director of infectious diseases preparedness and response at the Administration for Strategic Preparedness and Response.
If the virus changes and becomes a bigger threat to people, “we have the building blocks to produce a vaccine,” Boucher added.
An event attendee asked if the seasonal flu shot offers any protection. “Unfortunately, the flu shot you got last year does not provide great protection from the avian flu,” Shah responded. “It might do a little bit … but that is the vaccine for seasonal flu. This is something more novel.”
Treatments Stockpiled and Ready
Antiviral medications, which if given early in the course of bird flu infection could shorten the severity or duration of illness, are available now, Shah said. The dairy farmer who was infected with bird flu earlier this year responded to oseltamivir (Tamiflu) treatment, for example.
When it comes to bird flu symptoms, the fact that the only infected person reported so far this year developed pink eye, also known as conjunctivitis, is interesting, Shah said. Officials would have expected to see more typical seasonal flu symptoms, he added.
“Influenza is not a new virus,” Boucher said. “With this strain of influenza, we are not seeing any genetic markers associated with resistance to antivirals. That means the antivirals we take for seasonal influenza would also be available if needed to treat H5N1.”
ASPR has stockpiled Tamiflu and three other antivirals. “We do have tens of millions of courses that can be distributed around the country if we need them,” he added.
“Influenza is an enemy we know well,” Boucher said. That is why “we have antivirals ready to go now and many types of PPE.”
Science in Action
The feds intend to stay on the case. They will continue to monitor emergency department visits, lab test orders, and wastewater samples for any changes suggesting a human pandemic risk is growing.
“While we’ve learned a great deal, there are still many things we do not know,” Deeble said.
Shah added, “As in any outbreak, this is an evolving situation and things can change. What you are seeing now is science in action.”
