“Kangaroo care,” or skin-to-skin contact, may be neuroprotective and is associated with neonatal development in areas of the brain involved in emotional regulation in preterm infants, according to a new preliminary study from Weill Cornell Medicine, Burke Neurological Institute and Stanford Medicine investigators. Even short sessions correlated with noticeable effects on brain imaging scans, which is important because more than half of preterm infants have risk for neurodevelopmental impairment.  

The findings of the retrospective study, published Sept. 24 in Neurology, the medical journal of the American Academy of Neurology, could ultimately lead to better neurological outcomes for preterm infants and a wider adoption of kangaroo care in neonatal intensive care units (NICUs).

A multi-institutional team led by Weill Cornell Medicine investigators has been awarded a five-year, $20.8 million grant from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, for advanced preclinical development of a promising experimental HIV vaccine.

A successful vaccine to prevent new HIV infections would be a major public health breakthrough. About 1.3 million people acquired HIV in 2024, according to the World Health Organization, and at the end of that year an estimated 41 million people were living with the virus. Medication can keep individuals healthy but must be taken for a lifetime.

The new academic year is around the corner. You know who your child’s new teacher is, and you have the supply list. It’s also time to consider what vaccines are required for school. Why do kids need vaccines? 

“Vaccines are a tool that pediatricians use to help teach someone’s immune system,” says Dr. Sean Cullen, instructor in Pediatrics and Pediatric Scientist Development Program research fellow at Weill Cornell Medicine. “There are upwards of 20 vaccine-preventable diseases today—20 diseases children aren’t getting at the rates they did before the development of vaccines.” 

In a large hotel conference room at the end of February, hundreds of pediatrician scientists from all points urban and rural alike across the U.S. gathered to showcase their research, meet with mentors, and celebrate each other. The room was buzzing with energy, stemming from sparks of curiosity and pride. It would not be hyperbole to note that the some of the brightest minds and most noble physicians in pediatric research sat in the room that day, all members of a 40-year strong cohort of the Pediatric Scientist Development Program (PSDP).

For over four decades, PSDP has served as a vital pipeline for early-career pediatricians pursuing research careers aimed at improving child health around chronic disease and illness. Under the leadership of Dr. Sallie Permar, a distinguished physician-scientist and national leader in pediatric infectious disease research, the PSDP has continued to thrive as one of the most well- regarded training programs for pediatrician scientists in the United States.

The PSDP was designed to fill a critical gap, removing barriers to research access and training, including limited time, funding, and mentorship. The program provides a structured, intensive yet supportive environment in which early-career physicians receive dedicated mentorship, protected research time, and funding that allows them to pursue rigorous scientific training in basic, translational, or population health sciences.

When Ashley Merchant was four months pregnant, she and her husband, Mark, put on hold the celebrations they had planned for their baby’s arrival — the baby shower, the hospital visits from family, and the welcome home party. “I wasn’t really sure what the outcome would be, so we kept quiet for a while,” says Ashley. “Things were just not normal or happy for a long time.”

Ashley learned early in her pregnancy that she could face serious challenges. Eight weeks in, an ultrasound test indicated the baby was at risk of a chromosomal, structural or genetic condition. She and Mark were living in Maine at the time and raising their first child, Emmett, but given the complexity of her case, they started searching online for experts in other cities. Many people recommended Dr. Julianne Lauring, an OB-GYN and maternal-fetal medicine specialist at NewYork-Presbyterian/Weill Cornell Medical Center. Ashley grew up in the New York area, so when they visited home for Thanksgiving in 2023, she scheduled an appointment.

“Ashley came to my clinic where I have bedside ultrasounds, and as soon as I put the ultrasound on her belly, I knew there were some serious complications that we needed to consider,” says Dr. Lauring. “She told me to do anything we could to give her baby a chance.”

COVID-19 prevention methods such as masking and social distancing also suppressed the circulation of common respiratory diseases, leaving young children lacking immunity to pathogens they otherwise would have been exposed to, a new multi-center clinical research study reveals. The investigators say their findings help explain the large post-pandemic rebound in these diseases and enable more accurate predictions for the future.

Jennifer Weiss’s path to medicine began as a young child, when an ambulance responded to her New Jersey home to care for her dad, who has heart disease. During the scary episode, one of Weiss’s earliest memories, the emergency medical technicians and paramedics offered empathy and compassion and put everyone at ease.

Inspired to help others, Weiss trained as an EMT at age 16 and joined her local first aid squad. But she quickly realized that she wanted more.

“I wanted to have a greater impact on my patients than just the short ride to the hospital,” she said, “where my knowledge and skills stopped and the receiving physician’s skills took over.”

A $1.1 million grant from the parent-caregiver-led Rare Bird Foundation to Weill Cornell Medicine is supporting the launch of a natural history study for a rare neurodevelopmental disorder that causes developmental delays and seizures called MEF2C Haploinsufficiency syndrome (MCHS).

Currently, there are no specific therapies for MCHS, which affects about 400 people worldwide. Patients with the condition may experience developmental delays, difficulties communicating, and frequent seizures. The goal of the study, coined the Volāre Study, is to collect vital information about the condition to lay the necessary groundwork for future clinical trials of therapies for MCHS.

“The drive for this study comes from the parents of children with MCHS,” said principal investigator Dr. Zachary Grinspan, director of the Pediatric Epilepsy Program at Weill Cornell Medicine and vice chair of health data science for the Department of Pediatrics at Weill Cornell Medicine and NewYork-Presbyterian Komansky Children’s Hospital of Children’s Hospital of New York. “They share a sense of urgency to bring treatments to their kids and to others who have the disease. It makes the work very personal and meaningful for our team.”

The Department of Pediatrics is pleased to announce the appointment of Corinne Catarozoli, Ph.D., as Section Chief of Pediatric Mental Health at Weill Cornell Medicine, effective July 1, 2025. In this new role, Dr. Catarozoli will work closely with Cori Green, MD Vice Chair of Behavioral Health Integration and Innovation and Susan Bostwick, MD, MBA, Division Chief, General Pediatrics as we continue to expand our integrated and collaborative mental health services within our department.

As Section Chief of Pediatric Mental Health in the Division of General Academic Pediatrics, Dr. Catarozoli will provide overall leadership and direction of the section’s clinical activities and will partner with Dr. Green to develop a program bolstered by academic scholarship and advances in clinical innovation and research. Dr. Catarozoli, who joined the Department in 2025 and WCM in 2016, has worked with our department since 2017 to build and oversee our mental health services. Dr. Catarozoli launched the Youth Cope program, which provides short-term co-located mental health treatment to children in both subspecialty and primary care pediatrics. She founded and directs the Pediatric Psychology and Integrated Care Fellowship and Externship programs. Dr. Catarozoli is also a recent graduate of the WCM Wolk Leadership Fellowship Program.

The very first vaccine was created at the tail end of the 18th century by Dr. Edward Jenner, an English physician and scientist, to protect against smallpox. He injected his patients with the cowpox virus, a related but far milder infection. And, lo and behold, it worked. 

Jenner’s vaccine was refined later, but that “first” was one of the most stunning discoveries in the history of medicine. Smallpox was declared eradicated globally in 1980, with the last case reported in Somalia in 1977. 

In what follows, Dr. Sean Cullen— The Friedman Family Foundation Clinical Scholar in Newborn Medicine and Assistant Professor of Pediatrics and Weill Cornell Medicine—explains the ins and outs of vaccines, including:
