Minnesota newborns to be screened for Metachromatic leukodystrophy (MLD)
The Brief
The Minnesota Department of Health announced babies born in the state will be routinely screened for metachromatic leukodystrophy (MLD).
Officials said screenings for the disease will likely start in 2026.
MLD symptoms include patients not reaching developmental milestones, experiencing regression of skills, seizures and sometimes death.
MINNESOTA (FOX 9) - Babies born in Minnesota will start to be routinely screened for metachromatic leukodystrophy (MLD), the state's health department announced.
Officials say MLD will likely be added to the list of conditions Minnesota newborns are routinely screened for in 2026, based on the Newborn Screening Advisory Committee's recommendation.

Big picture view
MLD is a kind of lysosomal disease that is caused by an enzyme deficiency leading to a buildup of fats known as sulfatides.
Health officials say the buildup causes brain and nervous system damage, which can lead to those diagnosed with MLD not reaching developmental milestones, experiencing regression of skills, seizures and sometimes death.
There is no cure, but early intervention can slow progression of the disease and help manage symptoms.
The Minnesota Department of Health said gene therapy "offers a promising approach" to treatment. Such a case was the subject of the documentary "Sequencing Hope", which followed an Alabama family's journey to M Health Fairview Masonic Children's Hospital in Minnesota for their daughter's treatment.
Local perspective
The Minnesota Department of Health (MDH) said the start date for MLD screening in Minnesota will likely be in 2026, with an exact date being determined and shared when the process unfolds.
State officials add that Minnesota "has one of the most comprehensive newborn screening programs in the country" and point to screening for phenylketonuria (PKU) screening that started in 1964. Since then, all babies born in the state have had a blood sample sent to the Minnesota Department of Health for newborn screening unless parents opted out.
Minnesota has since expanded its newborn screening panel to detect more than 60 conditions, allowing affected children to get the care they need as quickly as possible, according to the MDH.

NYC EMTs say they're understaffed and feeling the strain during summer heat
Ambulance response times in New York City have jumped. During the summer months, paramedics say they get even more calls. They fielded more than 1,000 calls a day this week because of the heat wave. It comes as EMTs say there's a staffing shortage. Paramedic Edgar Romero, who has been on the job for 20 years, works at FDNY EMS Station 27 in the Bronx. He says there aren't enough ambulances for the amount of calls coming in. "This week, with the heat, it has been unbearable. It's been tough. It's just been very busy," Romero said. "We have jobs holding two hours, three hours, sometimes even four hours." "The Bronx is suffering the most" According to the union representing 4,200 paramedics citywide, 911 calls went up significantly during this week's heat wave. They say there were 5,296 Monday, 5,208 Tuesday, and about 5,600 Wednesday. That's compared to a daily average of 4,325. "It's definitely a strain because there's hardly any units out there," Romero said. We're told 15-20 additional units are needed in the Bronx just to keep up with the amount of calls coming in. "The Bronx is suffering the most. Most of the calls on hold are in the Bronx. We simply don't have enough ambulances," EMS Local 2507 president Oren Barzilay said. "The demand is higher than the resources." According to the mayor's management report, response times have slowed down too. In 2023, it was 10:43. In 2024, it was 10:42. So how about this year? "We're over 11 minutes for critical calls such as cardiac arrest," Barzilay said. "Every second does matter," Romero said. Paramedic Joseph Arnold has been on the job for 13 years. He works at Station 14, next to Lincoln Hospital. "When we get there we do everything we can, but sometimes there aren't ideal outcomes," Arnold said. Barzilay says a staff shortage and high turnover rates due to workload and salary are also impacting their jobs to save lives as fast as they can. "We've been without a contract for three years," Barzilay said. "We need a raise, that's for sure. We need more people to come help us out," Romero said. The city told CBS News New York: "Under the Adams administration, our first responders are - and will always be - prioritized and properly funded to handle emergency medical calls. These brave men and women are saving New Yorkers' lives every minute - particularly during a heat wave - which is why we are hiring EMTs as fast as we can train them. We will always respond to every emergency call in a timely fashion." The FDNY said responding to emergency medical calls quickly is a top priority. During a heat wave, calls are prioritized to get to the neediest New Yorkers as soon as possible.

What will the Supreme Court's Planned Parenthood ruling mean in Minnesota?
A major decision by the U.S. Supreme Court Thursday morning involving Planned Parenthood in South Carolina could have a ripple effect across the country. Legal experts say the ruling means that states will have the right to block Planned Parenthood's access to federal Medicaid funding for non-abortion services. That includes birth control, cancer screenings, reproductive care and more. Planned Parenthood South Atlantic was suing South Carolina for blocking the funding, but the high court ruled in the state's favor in a 6-3 vote. WCCO reached out to Planned Parenthood North Central States, which covers Minnesota, to see if there's concern that Medicaid patients here might face the same restrictions. They said that, as of Thursday, nothing will change in Minnesota for the 22,000 patients who sought care using Medicaid. "We want our patients to know that they will be able to continue to get care here in Minnesota under Medicaid, and we are doing everything that we can to live up to our committment to provide care and adapt in this every shifting environment," Ruth Richardson, president of Planned Parenthood North Central, said. "There's a lot of uncertainty in this moment, that is for sure with this manufactured chaos that we continue to see, and it seems to be ever-increasing in many ways. But the commitment and one thing we can rely on at this point is that we are continuing to see patients and we're going to be unwavering within that commitment." Last month, Planned Parenthood announced that four clinics would close in Minnesota, including two in the Twin Cities, due to a freeze in federal funding and budget cuts proposed in Congress. It's unclear if this new U.S. Supreme Court decision could impact more clinics. The dispute before the high court did not involve abortion, but it comes as several Republican-led states push to block Planned Parenthood from receiving any Medicaid funds.

These Are The 2 Best Workouts For Longevity, According To An Exercise Physiologist
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." If you're on a mission to live longer (and stronger!), you probably know that regular exercise plays an undeniable role in longevity. Walking and strength training in particular have a ton of benefits that can help keep you movin' and groovin' for years to come—but is one of them better at adding healthy years to your lifespan? And how should you balance walking and strength training to create a holistic routine? Those questions were recently raised by Blue Zones, an organization committed to researching worldwide longevity. Via the Instagram account, the org posted about how if you want to live to 100, walking every day is better than going to the gym three or four times per week. Meet the experts: Sarah Pelc Graca, CPT, is a certified personal trainer and founder of Strong with Sarah Weight Loss Coaching. Rachelle A. Reed, PhD, ACSM-EP, is an exercise physiologist in Athens, Georgia. Natalya Vasquez, CPT, is a certified personal trainer, health coach, and founder of On Your Terms Coaching. Even though most of us do it every day, walking is having a moment of sorts—due to the fact that it's a low-impact workout that benefits your cardiovascular system and is accessible any time, any place. But strength training is also increasingly important as you age since it preserves muscle mass, bone density, and functional strength, says Sarah Pelc Graca, CPT, a certified personal trainer and founder of Strong with Sarah Weight Loss Coaching. That just scratches the surface, though. Here's the lowdown on exactly how walking and strength training each impact longevity, and what that means for your routine, according to experts. Expert verdict: It's a tie Keeping your brain healthy is a big part of living a longer, better life. 'When your mind stays sharp, it's easier to stay independent, connected, and active,' Pelc Graca says. On the flip side, cognitive decline can lead to accidents, memory loss, and even depression, she says. Fortunately, when it comes to supporting brain health and cognitive function, walking and strength training are both amazing, but in different ways. 'Walking increases blood flow to the brain, which boosts oxygen and nutrients to the areas responsible for memory and thinking, but it also helps lower stress and improve sleep, which are two big players in cognitive health,' Pelc Graca says. In fact, aiming for around 10,000 steps a day may even be associated with a lower risk of developing dementia. A 2022 study in JAMA Neurology monitored almost 80,000 adults ages 40 to 79 over about seven years and monitored how many steps they took each day. It found that walking more was associated with a lower risk of dementia, and the optimal amount of daily steps was just under 10,000. Strength training, on the other hand, stimulates the release of growth factors (naturally occurring substances that stimulate cell growth), which supports the formation of new neurons in the brain, Pelc Graca says. Lifting weights may also improve executive function and memory, per a 2022 review in Springer Open that looked at 19 studies on the effects of resistance training on cognitive function. A combination of walking and resistance training is the ideal recipe for optimal brain health—and this finding is supported by a 2025 review in the International Journal of Clinical and Health Psychology that looked at 35 randomized controlled trials to determine the effects that aerobic and resistance training have on cognitive function. 'Walking can be a great gateway to more intense exercise, and may be the best starting place for folks who haven't been active in a while, but ideally, it's best to work up to incorporating both types of exercise' for longevity, says exercise physiologist Rachelle A. Reed, PhD, ACSM-EP. Expert verdict: Strength training Strong bones are key to staying active and avoiding serious injuries as you get older, because broken bones—especially in older adults—can lead to long recovery times and even long-term health issues, Pelc Graca says. The good news? Weight-bearing movements like walking and resistance training help maintain and improve bone mineral density, the amount of bone mineral in bone tissue, so you're less likely to experience fractures and more likely to stay on your feet for the long haul. Strength training has a slight edge at this over walking. Walking slows age-related bone loss, especially in the hips and legs, since your bones work to support your body weight with each step, stimulating them to become stronger and denser, Pelc Graca says. As a result, frequent walks may reduce the risk of osteoporosis, per 2024 research in Springer. The study monitored 24,000 adults without osteoporosis over three years via questionnaires and found that those who engaged in outdoor walking regularly had a lower risk of osteoporosis. Strength training does more than just slow bone loss, though—it also stimulates new bone growth. 'Strength training puts controlled stress on bones, signaling the body to build stronger, denser bone tissue,' Pelc Graca says. You can certainly add weight to your body while walking (hello, weighted vest), but there are limitations on the range of motion and weight you can use that actually impact bone preservation and muscle growth, says Natalya Vasquez, CPT, a certified personal trainer, health coach, and founder of On Your Terms Coaching. However, the different exercises and directions your body moves weights in during resistance training also improves muscle mass, meaning better support for your skeleton, Vasquez says. This is particularly beneficial for older women and those post-menopause, since it helps counteract the bone loss that often occurs during this phase of life, according to a 2022 review in Endocrinology. Expert verdict: Walking Heart health has a huge impact on how long—and how well—you live since heart disease is the number one cause of death for women. As a result, taking care of your cardiovascular system is nonnegotiable for boosting longevity and fostering a longer, healthier lifespan, Pelc Graca says. Walking shines when it comes to supporting cardiovascular health, but strength training still plays a valuable role. Walking boosts circulation, lowers blood pressure, supports healthy cholesterol levels, and improves insulin sensitivity, which are all key factors for keeping your heart in tip top shape, Pelc Graca says. Regular exercise like walking also helps manage stress, which can decrease blood pressure and the risk for heart attack and stroke, per the American Heart Association. Plus, because walking is low-impact, accessible, and doesn't require equipment, it's easier to do regularly, which is critical for long-term heart health, says Reed. That said, strength training still plays a valuable role in cardiovascular health since it reduces body fat, improves insulin sensitivity, and lowers mortality risk, per a 2023 review in Exercise Sport and Movement that reviewed studies examining the long-term benefits of resistance training. However, during traditional strength training, you'll likely take frequent rest breaks between sets where your heart rate will slow down, whereas your heart rate won't decrease on a walk, which will make it stronger over time, Vasquez says. Expert verdict: Strength training Muscle isn't just for looking sculpted—it's key to staying strong, steady, and independent as you age. A lack of muscle is also correlated to poor balance and an increased risk of falls, in turn, upping your chances of injury, says Pelc Graca: 'Put simply, more strength equals more freedom to do the things you love for longer.' Strength training takes the cake for building muscle, but walking still supports muscle maintenance. Strength training is the most effective way to build muscle and maintain muscle mass, which both naturally decline with age, Pelc Graca says. Resistance training provides a heavy load to the muscles, which will stimulate muscle growth (hypertrophy). It also improves neuromuscular coordination, the communication between the brain and the muscles, which enables movement, Reed says. This workout also enhances joint stability, balance, and improves range of motion, allowing you to stay stronger and independent for longer, per a 2023 meta-analysis in Springer of 55 studies on the benefits of resistance training. Besides strength, training power is also imperative for being able to move well for as long as possible. 'Unlike muscular strength, which refers to how much force a muscle can exert, muscular power combines force and speed,' says Reed. So, maintaining that power is important to do functional tasks like climbing stairs, catching yourself during a fall, or quickly standing up from a chair. Incorporating power movements like medicine ball throws and kettlebell swings during strength training days can help maintain that force and speed. As for walking, Pelc Graca says regular strolls preserve lower-body strength and endurance, especially in the calves, hamstrings, glutes, and core. Walking also promotes healthy joints and balance, making it easier to move freely and confidently with age. However, because walking is a singular range of motion exercise (you only move forward and backward), it excludes other major muscle groups from activating, therefore limiting overall muscle gains and strength, Vasquez says. Expert verdict: Both! Walking and strength training both play an invaluable role in health and longevity. All three experts agree that a hybrid exercise model emphasizing aerobic movement and resistance training is your best bet for a longer, healthier life. The Centers for Disease Control and Prevention recommends at least 150 minutes of moderate intensity exercise per week—like a brisk walk—plus a weekly minimum of two full-body strength training sessions. However, you can tailor your workout routine to your individual interests and health concerns. For instance, 'older adults may benefit more from prioritizing strength training to preserve muscle mass and prevent frailty, while individuals with cardiovascular risk factors often need more aerobic activity like walking,' Reed says. 'For those just getting started with exercise, walking is typically a more approachable and confidence-building entry point.' If you're unsure where to start, Vasquez recommends walking for 15 minutes after lunch and dinner everyday and adding three 15-minute full-body strength training sessions to your schedule throughout the week. From there, you can increase the time and intensity as your body gets stronger. Remember, as with most things in life, consistency is key for long-term success. 'Longevity isn't just about adding years to your life,' Pelc Graca says. 'It's about adding life to your years, and regular walking and strength training are two of the most accessible, effective ways to do that.'
