Imagine empowering every home health aide with the tools and training to deliver specialized, quality care for patients with heart failure.

As our population ages, the demand for home health care workers is increasing, and they lack the support they need. For example, in New York City alone, about 65% of home health aides report receiving little to no training in monitoring patients with heart failure, and nearly half say they can't reach nurse or doctor when they need help managing patients at home.

Dr. Madeline Sterling of Weill Cornell Medicine is leading a training program to offer specialized training for home health aides on heart failure, which is one of the most common conditions among home care patients.

The program also introduces technology to the workforce, including a way for aides to securely message nurses in real time. She found that these efforts lead to fewer 911 calls among home health aides and ER visits among patients.

Here's What We Know:
• Better training and tech-based communication tools for home health aides can improve patient care.
• Better care means healthier patients at home, fewer hospital readmissions, and lower costs for the health care system.

This study was made possible through collaboration with VNS Health, Weill Cornell Medicine, Cornell Tech, funding from the National Institutes of Health, and the dedication of home health aides.

Dr. Arnab Ghosh was an ER doctor in Australia when he treated many patients with severe burns from bushfires that swept through the region. At the time, evacuations were not mandatory.

"For the fires that hit those communities, they were faster and stronger than anyone expected. Many people perished in their homes," recalls Dr. Ghosh, an internal medicine physician at Weill Cornell Medicine and NewYork-Presbyterian Hospital.

Those experiences shaped Dr. Ghosh's career as a doctor and set him on the path as a researcher who focuses on climate and health policies that can save people's lives.

"Our role as doctors, healthcare systems, communities and governments that implement policies is to reduce extreme weather event risks from climate change for the most vulnerable populations," he says. "The science is only part of what we do. We need to garner trust and connect with patients."

Dr. Ghosh's work shows the importance of lasting connections. His recent study examined older adults residing in areas that flooded during Hurricane Sandy. It found that they faced a 5% higher risk of heart disease for up to five years after the hurricane.

"Weather disasters don't just have short-term impacts -- these are problems that will echo through people's lives," he says.

Dr. Ghosh's unique background makes him well-suited to both respond to disasters and understand the human side of them.

The son of an Indian immigrant and Burmese refugee, Dr. Ghosh grew up in Australia. In college, he studied Latin and Greek, served in the military, and later worked in peacekeeping for the United Nations. He did the majority of his medical training in the Australian outback, learning to practice medicine with few resources.

In 2018, he joined the NewYork-Presbyterian team that went to Puerto Rico after Hurricane Maria to provide care in a field hospital with limited supplies.

As extreme weather, fueled by climate change, becomes more frequent, Dr. Ghosh says we need to envision what that means for health care in the future.

"How can we take science and research and transform the policy landscape to influence the well-being of people?" he says.

Pancreatic cancer is known as the "silent killer" because symptoms often appear only in advanced stages. The pancreas plays a crucial role in regulating blood sugar levels and facilitating the digestion of food. Symptoms like stomach pain, weight loss, and jaundice can be easily overlooked.

Risk factors include age, with higher rates in African American women, along with family history, chronic pancreatitis, Type 2 diabetes, smoking, obesity, and high consumption of red or processed meats.

Diagnosis typically involves physical examinations, blood tests, imaging tests such as MRIs or ultrasounds, and a biopsy. Treatment options vary by cancer stage, including surgery, chemotherapy, and new approaches like immunotherapy and targeted therapies.

Ever wonder what mRNA vaccines are and how they were developed?

Even though it may seem like these vaccines appeared overnight, they resulted from more than 30 years of research and rigorous clinical trials.

COVID-19 vaccines marked a major breakthrough in mRNA technology. These vaccines instruct our cells to make a spike protein found on the virus. This triggers an immune response to fight the virus if it enters our bodies. The mRNA molecules are eliminated after providing us with protection.

"We still see hospitalizations and deaths from COVID every day, making it even more important to stay current with your COVID booster shots," says Dr. Roy Gulick, Chief of the Division of Infectious Diseases at Weill Cornell Medicine.

Here's What We Know:
✅mRNA COVID vaccines are built on decades of research and are adaptable to new variants
✅They are faster and less expensive to develop than traditional vaccines.
✅Research funding will help create more vaccines for widespread diseases like bird flu, and has the potential to develop new treatments for certain cancers and genetic disorders.

At 12 years old, Brayden Knapp is a typical, outgoing New Jersey kid. He plays travel hockey and baseball, loves water parks and is excited for sixth grade. But his journey started with a complex medical challenge.

At birth, Brayden was diagnosed with hydrocephalus, Chiari malformation, and craniosynostosis. “His skull was closed,” says his mom, Kristen. “There was no room for his brain to grow. It had to be reconstructed.”

The diagnosis was overwhelming. “It was scary,” Kristen says. “The hardest part was that it was out of our hands.”

Through a hockey connection, Brayden’s dad Ryan met Dr. David Wells-Roth, who referred them to pediatric neurosurgeon Dr. Mark Souweidane at Weill Cornell Medicine. “From the first appointment, he was reassuring and compassionate,” Ryan says.

At just two months old, Brayden had a seven-hour cranial vault reconstruction. “I prayed everything would work out—and thank God it did,” Kristen says. He later had surgeries for hydrocephalus and Chiari malformation.

Brayden wore a Superman onesie to his first surgery. After each appointment, they took a photo with Dr. Souweidane, a tradition that now spans a decade. “He’s so small in the early photos,” Ryan says. “Now they’re smiling and laughing.”

Kristen’s advice to other parents: “You’re not alone. Trust your child’s strength. Lean on your medical team, ask questions, and find support groups. Celebrate every milestone.”

“Dr. Souweidane saved my son’s life—and his way of living,” Kristen says. “Not just as a doctor, but as a person.”

From a newborn in a Superman onesie to a thriving 11-year-old athlete, Brayden’s story is one of resilience, hope and expert care.

You can’t see them, but they’re in the air you breathe, the food you eat, and the water you drink. As everyday plastics break down, they become tiny particles called microplastics that are now found everywhere, from our oceans to our bodies.

These particles contain toxic chemicals that can affect your health, with early research linking them to serious issues like diabetes, high blood pressure, and even infertility. While it's impossible to avoid them altogether, you can reduce your exposure by making small changes, such as replacing plastic containers with glass.

It's a small step, but it's a vital one for your well-being.

Dr. Laura Alonso’s commute to work starts out ordinary. She rides the Long Island Railroad to Manhattan, and that’s where her trip takes an unconventional turn.

In running gear and carrying a backpack, Dr. Alonso emerges from the train station and runs 1 ½ miles to her Weill Cornell Medicine office, where she is chief of the Division of Endocrinology, Diabetes, and Metabolism and director of the Weill Center for Metabolic Health.

After a quick shower and outfit change, she is at her desk by 8 a.m. and ready to tackle her day as a scientist, diabetes specialist and center leader.

"I tell my patients that I run and that I love how exercise makes my body and mind feel," she says.

After work, she runs back to the train, logging additional miles in Central Park as she prepares for the TCS New York City Marathon.

“My run commute allows me to have a real transition between work and home. It’s a great release from the day. Running is rejuvenating and restorative for me.”

Dr. Alonso was a competitive swimmer in college before switching to running. She ran her first marathon in Pittsburgh in 2013 and went on to run the prestigious Boston Marathon five times.

She always wanted to run the NYC Marathon and finally did in 2024.

"It felt like a celebration," she recalls. "People are dancing. There are dogs, kids and spectators who support us. There was so much pride for the city itself."

Slightly hampered by an injury last year, she is back this year with the goal of finishing faster. She's added weight-bearing exercises into her routine to help prevent injuries. "Strength training has been the biggest change to my running. I do squats and lunges before I run," she says. "Particularly women need strength training for bone health."

On the weekends, in between work emails, she puts in a 20-mile run. To keep herself going, she packs a peanut butter and jelly sandwich and energy gels in a waist pouch and carries an electrolyte drink.

Although the training is challenging, she looks forward to soaking in 26.2 miles through the five boroughs.

"I hope to have a great experience with all my fellow New Yorkers. I love the excitement and the city coming together."

Let’s Clear Things Up About Thimerosal and Vaccines

You may have heard discussions about mercury in vaccines. Here's what we know about the ingredients in vaccines.

Thimerosal is a preservative used in some vaccines to prevent bacterial contamination.

Dr. Karen Acker explains that thimerosal contains a type of mercury called ethylmercury, which is very different from methylmercury, the kind found in some fish that can build up in the body. Ethylmercury breaks down quickly and doesn’t stay in the body.

Here's what we know:
• There is no link between thimerosal and autism or other neurodevelopmental conditions in children.
• Scientific studies have found no evidence of harm from the low doses of thimerosal used in vaccines.
• Vaccination remains one of the safest and most effective ways to prevent infectious diseases and protect public health, especially for children and older adults.

If you have any questions, please talk to your doctor.

Tuberculosis (TB) has claimed more lives than any other disease in history and remains a significant global health challenge, especially in developing countries. While the U.S. has low TB rates, recent increases show the need for strong public health systems.

Thankfully, TB is treatable with antibiotics, but lengthy treatment regimens can lead to non-compliance and drug resistance, making it harder to fight.
