Mount Sinai Researchers Show That Early Intervention in Preschool Is a Unique Opportunity for Promoting a Healthy Lifestyle

Natalia Leal and her son Gabriel are participants in FAMILIA, which instructs preschoolers and their families on cardiovascular health.

Children may have a better chance of avoiding unhealthy habits linked to obesity and cardiovascular disease later in life if they are taught properly about healthy behaviors in preschool, Mount Sinai researchers have shown in a first-of-its-kind study.

The researchers focused on children living in a socioeconomically disadvantaged community, a situation that is commonly linked to higher rates of obesity, heart disease, and other health issues. Valentin Fuster, MD, PhD, Director of Mount Sinai Heart and Physician-in-Chief of The Mount Sinai Hospital, created and led the trial, called the FAMILIA Project at Mount Sinai Heart. The results were published in the April 22 online issue of Journal of the American College of Cardiology.

Road to Resilience Episode 11: The Long Arm of Childhood Trauma

Recording the Road to Resilience podcast are actor Darrell Hammond, in hat, and, clockwise, filmmaker Michelle Esrick, Mount Sinai podcast producer Jonathan Earle, and Jacob Ham, PhD.

A regular cast member for 14 seasons on Saturday Night Live, Darrell Hammond entertained millions with his spot-on impersonations of Bill Clinton, Donald Trump, Sean Connery, and others.

But behind the scenes, he endured debilitating flashbacks, substance abuse, and self-harm. Misdiagnosed and medicated for decades, it wasn’t until Mr. Hammond was in his 50s that he finally received the correct diagnosis: childhood trauma.

In the latest episode of the Road to Resilience podcast from the Icahn School of Medicine at Mount Sinai, Mr. Hammond and filmmaker Michelle Esrick sit down with Jacob Ham, PhD, a clinical psychologist and Director of the Center for Child Trauma and Resilience at the Icahn School of Medicine at Mount Sinai, to discuss childhood trauma, complex post-traumatic stress disorder (PTSD), and healing. They talk about the long-term health effects of childhood trauma, how to deal with triggers in daily life, and the ways loved ones can support survivors in their recovery.

Jacob Ham, PhD

Mr. Hammond’s experience with trauma, addiction, and recovery is explored in a new documentary film, Cracked Up, directed and produced by Ms. Esrick.

Cracked Up explores the lifelong effects of childhood trauma, addiction and recovery through Mr. Hammond’s inspiring story. It features extensive interviews with Mr. Hammond, as well as leading trauma experts such as Bessel van der Kolk, MD, psychiatrist and author of The New York Times bestseller The Body Keeps the Score: Brain, Mind, and Body in the Healing of Trauma.

Road to Resilience brings you stories and insights to help you thrive in a challenging world. From fighting burnout and trauma to building resilient families and communities, the podcast explores what’s possible when science meets the human spirit.

A Novel Approach to Making Organ Transplants Successful

Study co-authors, from left: Zahi Fayad, PhD, Director of the Translational and Molecular Imaging Institute; and Willem J.M. Mulder, PhD, Professor of Radiology, and Oncological Sciences.

The nearly 35,000 individuals who receive organ transplants each year in the United States face a harsh reality: the immunosuppressive drugs they must take to maintain organ survival also weaken the immune system, breaking down the body’s critical defenses against cancer, infection, and more. Researchers at the Icahn School of Medicine at Mount Sinai recently developed an innovative type of immunotherapy based on nanotechnology that they hope will address this conundrum. Their findings, published in the November 6, 2018, issue of Immunity, have demonstrated the technology’s feasibility of long-term organ acceptance in mice.

“This is a whole new approach to programming the immune system, not just another small molecule drug that’s going to help with organ transplantation,” says Zahi Fayad, PhD, Director of the Icahn School of Medicine at Mount Sinai’s Translational and Molecular Imaging Institute, which conducted the work. Dr. Fayad is also Professor of Diagnostic, Molecular, and Interventional Radiology, and Medicine (Cardiology). “Because of the many problems this approach addresses—the risk of rejection, the shortage of organs for transplant, the cost of these procedures—we believe it can be transformative for the organ transplant field.”

Jordi Ochando, PhD

The immunotherapy works by regulating innate immune memory, or trained immunity, which the investigators found to play a central role in organ rejection. In trained immunity, immune cells known as myeloid cells initiate the body’s immune system response by activating T cells, which then attack the transplanted organ.

“By inhibiting trained immunity, we prevent activation of the myeloid cells and their subsequent activation of T cells,” says Jordi Ochando, PhD, the study’s co-senior author, who is Assistant Professor of Medicine (Nephrology), Oncological Sciences, and Pathology at the Icahn School of Medicine. “This novel technology preserves the normal function of the T cells, which is to protect the body against cancer and infections.”

Identifying trained immunity as a target enabled the Mount Sinai scientists to focus on a signaling pathway known as mammalian target of rapamycin (mTOR), which regulates immune cell metabolism. The team developed an injectable nanoimmunotherapy based on high-density lipoprotein (HDL) nanomaterials and the existing mTOR inhibitor rapamycin.

“These nanomaterials essentially deliver the rapamycin to the myeloid cells, and that changes the metabolic state of the cells and prevents their activation,” says co-senior author Willem J.M. Mulder, PhD, Professor of Radiology, and Oncological Sciences at Icahn School of Medicine, and Director of the Nanomedicine Program. The absence of myeloid cell and T cell activation, Dr. Mulder points out, could drastically reduce the need for transplant patients to take lifelong immunosuppressive medicines to prevent graft rejection.

A Rare Bladder Condition, and in Need of a Kidney Transplant: Little Lexi’s Extraordinary Medical Journey

Lexi Isler got a kiss from her father, Luther, before the kidney transplant surgery in January.

In 2009, when a prenatal ultrasound showed an abnormal kidney, Luther and Ashley Isler knew that their daughter, Lexi, would be born with a urinary problem. What they did not expect, however, was that Lexi would also be born without a bladder, a condition known as bladder agenesis that has only 20 known survivors worldwide.

Today, 8-year-old Lexi is among those remarkable survivors as she continues an extraordinary medical journey supported by her loving family and an interdisciplinary team of Mount Sinai physicians that has included pediatric urologists and nephrologists, and transplant surgeons, along with nurses and countless other caring staff over the years.

When Lexi was 2 years old, doctors at Mount Sinai Kravis Children’s Hospital confirmed by magnetic resonance imaging that urine had been backing up into her kidney—because she did not have a bladder. While she was in diapers, not having a bladder was not immediately obvious, but as she grew older, Lexi would need a way to both hold and pass urine. Meanwhile, her kidneys—damaged by her urinary outflow anatomy—had been steadily deteriorating and doctors realized that she would eventually need a kidney transplant.

Lexi’s urology and pediatric doctors formed a close team to strategize about her case from the earliest stages. “Long before a transplant, our team first had to think about how to make a bladder and how to get it to work,” says Jeffrey M. Saland, MD, Chief of Pediatric Nephrology and Hypertension at Mount Sinai Kravis Children’s Hospital and Medical Director of the Pediatric Kidney Transplant Service.

When Lexi was 5 years old, Jeffrey A. Stock, MD, Associate Professor of Urology, and Pediatrics, Icahn School of Medicine at Mount Sinai, and Chief of the Division of Pediatric Urology at Mount Sinai Kravis Children’s Hospital, performed the complex, six-hour surgery to create an artificial bladder.

“We removed part of her colon and connected the ends to create a bowel pouch that functioned as a bladder,” says Dr. Stock. “Then, we used her appendix to create a urethra to drain urine from the neobladder.” The neobladder can store, but not empty, urine so Lexi has learned to use a catheter in the bathroom to empty her new bladder. The neobladder procedure is rare. Dr. Stock, who specializes in the surgical reconstruction of genitourinary birth defects, has done only four such procedures in his 25 years of practice.

By January 2018, Lexi’s kidney function was so compromised that at one point, she was unresponsive for days. The situation remained critical all year with very little improvement, and in December 2018, the need for a kidney transplant could not be deferred. Fortunately for Lexi, when she was 3, her father had been identified as a match for her. “It was an easy decision,” says Mr. Isler. “I felt blessed that I was a match.”

In January 2019, as Lexi was about to go into kidney failure, surgeons from the Recanati/Miller Transplantation Institute at Mount Sinai performed the transplant using her dad’s kidney. “We had all of our firepower available,” says Ron Shapiro, MD, Professor of Surgery, and Surgical Director of the Kidney and Pancreas Transplant Program, referring to the expert team of surgeons involved with the transplant and the bladder creation. A smiling Lexi was discharged after spending nine days in the hospital for the transplant surgery.

Still, says Dr. Saland, “This is a work in progress. Lexi remains at higher risk for urinary tract infections and we’ll need to make ongoing adjustments for drainage as well as in her anti-rejection medications. But at Mount Sinai, we believe we have all the expertise and resources we need to treat all aspects of Lexi’s condition.”

“I have the utmost respect for the doctors and nurses at Mount Sinai,” says Ms. Isler. “They all treated Lexi with so much respect and love. The nurses even came to her bedside when their shifts were over to paint with her.”

Despite periodic hospital stays, Lexi is happy and back at school, facing her health challenges with grace and an amazingly positive attitude for a girl her age, says Ms. Isler. Lexi recently found the courage to stand before her classmates and tell them about the condition she was born with and how it was treated. “Her classmates have been very supportive, and they don’t treat her like she’s different,” says Ms. Isler.

At home, the child who had been taking dance classes since the age of 2 has newfound energy and dances around the house with a lack of inhibition, Mr. Isler says. “With a lot of support, our goal is to enable Lexi to live a long, happy, and healthy life,” says Dr. Stock.

Inaugural Symposium Explores Women’s Health

Howell, MD, MPP; Vivian Pinn, MD; Michael Brodman, MD, the Ellen and Howard C. Katz Chair of Obstetrics, Gynecology and Reproductive Science, Icahn School of Medicine at Mount Sinai; Lynne Richardson, MD, Vice Chair for Academic, Research, and Community Programs, Icahn School of Medicine at Mount Sinai; Susan Domchek, MD, Executive Director, Basser Center for BRCA, Penn Medicine; and Stephanie V. Blank, MD, Director of Gynecologic Oncology, Mount Sinai Health System.

Why are more women than men hospitalized for schizophrenia after age 50? How should a bipolar pregnant woman be medicated? What should the study of women’s health encompass?

These were some of the questions posed recently by leading physician-scientists at the inaugural symposium of The Blavatnik Family Women’s Health Research Institute at the Icahn School of Medicine at Mount Sinai—“Cutting-Edge Topics in Women’s Health.”

The keynote speaker of the symposium, held in Davis Auditorium, was Vivian Pinn, MD, the first Director of the Office of Research on Women’s Health at the National Institutes of Health (NIH). She delivered a lesson on the not-so-distant past, saying, “Until the 1990s, most women’s health research was related to the reproductive system or the breasts—what is known as ‘bikini medicine’—and most studies of conditions that affect both men and women were conducted only in men.”

The symposium focused on issues such as equity in research, and health conditions that end women’s lives prematurely or significantly reduce their quality of life.

“These topics are a reflection of the broad research portfolio of The Blavatnik Family Women’s Health Research Institute and our strong commitment to health equity,” said its founding Director, Elizabeth A. Howell, MD, MPP, Vice Chair of Research and Professor of Obstetrics, Gynecology and Reproductive Science, and Professor of Population Health Science and Policy at the Icahn School of Medicine. The Blavatnik Family Foundation in 2018 provided a $10 million gift to establish the Institute and its clinical counterpart, The Blavatnik Family – Chelsea Medical Center at Mount Sinai. Dr. Howell said she is grateful to the family for their generous gift and support of the Institute.

Mental health is one area in which sex differences are clear, said Veerle Bergink, MD, PhD, Professor of Psychiatry, and Obstetrics, Gynecology and Reproductive Science, Icahn School of Medicine. Dr. Bergink said women are particularly vulnerable during pregnancy, which she and other panelists called a “stress test” that can trigger underlying autoimmune or mental health disorders. Her evidence-based treatment strategy, published in the December 2016 American Journal of Psychiatry, concluded that women who have bipolar disease or previous postpartum psychosis could avoid a relapse if they are treated with lithium soon after delivery.

An important area for further study is schizophrenia in post-menopausal women, Dr. Bergink said. Until age 50, the disorder is more prevalent in men, but there is a sudden turning point after 50 when more women are hospitalized for schizophrenia than men. An “estrogen hypothesis” proposes that the hormone has a protective effect that declines after menopause. “But we know very little about this,” Dr. Bergink said. ”Most of the schizophrenia research over the last 30 years has investigated men, and very little has focused on women.”

Another area for further study is the influence of pregnancy complications on women’s health in later life, said Laura E. Riley, MD, Professor and Chair of Obstetrics and Gynecology, Weill Cornell Medicine. Dr. Riley said that 7 to 10 percent of pregnant women in the United States are diagnosed with gestational diabetes and up to 9 percent contract preeclampsia, characterized by dangerously high blood pressure. Studies have shown that such complications are associated with cardiovascular disease and type 2 diabetes later in the lives of these women, Dr. Riley said, and there are many medical and behavioral interventions to be explored.

“For those of you looking for research projects, these might be good ones,” she said, “because I don’t think this story is over.”

Attendees received expert grant-writing advice from Andrea Dunaif, MD, Chief of the Hilda and J. Lester Gabrilove Division of Endocrinology, Diabetes and Bone Disease, and the Lillian and Henry M. Stratton Professor of Molecular Medicine, Icahn School of Medicine, whose groundbreaking research into diabetes and polycystic ovary syndrome has been continuously funded by the NIH since 1985. Dr. Dunaif also addressed more complex challenges, such as adhering to the “sex as a biological variable” policy, which since 2016 has required researchers to factor sex into the design, analysis, and reporting of any study that involves humans or vertebrate animals. 

“A little-known fact is that only the males get diabetes in almost all animal models of diabetes. Studies have found that the protection of female sex—both hormonal and chromosomal sex—is powerful,” Dr. Dunaif said. “But that begs the question of why? This is very important scientific question. I’m sure there are many more disease models in which there are major sex differences, and those should be studied.” 

Inclusive research is a key legacy of Dr. Pinn, who retired in 2011. The office she led was established in 1990, after four congresswomen called for action on women’s health research. Since then, studies have documented sex differences in the prevalence, age of onset, and severity of autoimmune diseases, depressive disorders, diabetes, and cardiovascular disease. “And there is still much to learn,” she said, “about the process of moving from discovery to treatment.”
