Penn and CHOP Researchers Receive $50 Million in NIH Grant to Study Impact on Environmental Factors on Pregnancy and Children’s Health
[10/05/23] Alex Gardner for Penn Medicine News: "'We are thrilled to have been chosen as an ECHO Cohort Study Site and for the opportunity to contribute to this important project, which will improve our understanding of the ways the local environment affects our children's health,' said Heather Burris, MD, MPH, an attending neonatologist at CHOP and co-lead investigator of the Penn-CHOP study site. 'We know that communities are not equally exposed to environmental toxicants, and we also know that health inequities and disparities are an ongoing public health problem. This project will help us shed light on the extent to which the health inequities we see in our patient population are related to neighborhood environmental exposures.'"

[08/28/23] Alex Gardner for Penn Medicine News: "Penn Medicine will serve a critical role in driving research to reduce pregnancy-related complications and deaths and promote maternal health equity through a new National Institutes of Health (NIH) grant. The $19 million, seven-year grant funds the creation of an implementation science hub as part of the NIH’s new Maternal Health Research of Centers of Excellence initiative.
"Through this initiative, the NIH has funded 10 centers of excellence research centers, the implementation science hub, and a data innovation hub to support research to reduce pregnancy-related complications, deaths, and promote maternal health equity. The implementation science hub team—led by Meghan Lane-Fall, MD, MSHP, the David E. Longnecker Associate Professor of Anesthesiology and Critical Care, and Rebecca Hamm, MD, MSCE, an assistant professor of Maternal Fetal Medicine, both in the Perelman School of Medicine at the University of Pennsylvania—will work with these centers on development, execution, and analysis of their research, to help bring findings into clinical practice and community settings. The hub is called AMETHIST@Penn, which stands for Achieving Maternal Equity and Transforming Health through Implementation Science and Training." Read more of "$19 Million from NIH"
[06/21/23] Hoag Levins for the Leonard Davis Institute of Health Economics: "Long outliers in the modern world of hospital maternity care units, doulas have been making increasing inroads into those clinical spaces as the U.S. struggles to address its maternal mortality crisis. Those advances are likely to be further broadened by the March of Dimes' funding of a new University of Pennsylvania Research Center for Advancing Maternal Health Equity and its research project aimed at determining how doulas can be more closely integrated into maternal care teams."

[06/20/23] Nicole Fullerton for Penn Medicine News: "For the past several years, Penn Medicine has been taking bold action to reverse maternal health disparities. In the United States, Black women are approximately three times more likely to die from pregnancy-related complications than white women. In addition to higher maternal mortality rates, low-income women and women of color face disparities when accessing key preventive obstetric and gynecologic health services, including screenings, immunizations, contraception, and specialized care.
"As a national leader in obstetrical care, Penn Medicine is taking steps to improve maternal health outcomes and reduce racial and ethnic disparities with a multi-pronged approach that encompasses research, clinical care, and community engagement. For example, a new national March of Dimes research center led by Penn is one of the latest drivers of new research to improve Black maternal health.

Remote Blood Pressure Monitoring After Pregnancy May Stave Off Postpartum Health Issues for Women with Preeclampsia
[05/10/23] Alex Gardner for Penn Medicine News: "'Our previous work showed that Heart Safe Motherhood made important blood pressure monitoring easier and eliminated racial disparities in obtaining blood pressures in the two weeks after giving birth,' said study author Adi Hirshberg, MD, director of Obstetrical Services at the Hospital of the University of Pennsylvania, who along with, senior author of this study, Sindhu Srinivas, MD, a professor of Obstetrics and Gynecology at Penn, developed Heart Safe Motherhood. 'What this study really solidified is that the benefits continue long-term. Close but remote tracking of blood pressure during this short yet pivotal time led to healthier moms months later.'"

[04/16/23] Meagan Raeke for Penn Medicine News: "Despite recent advances, ovarian cancer remains the fifth leading cause of cancer-related deaths among women, and there’s a critical need for new treatment options, especially for advanced cancers that grow back after standard of care treatment. Results from a preclinical study, led by researchers from the Perelman School of Medicine at the University of Pennsylvania, verified a new target for drug-resistant ovarian cancer and provided data to support a treatment approach that is already making its way into clinical trials.

[02/28/23] Kirsten Weir for Penn Medicine News: "Imagine cancer as a line on a chalkboard. At the left is a healthy cell. Reading left to right, you can follow a cell's journey as it begins to develop abnormalities, morphs to become a localized cancer, and finally metastasizes to an advanced cancer at the far side of the spectrum. 'As a field, we've been spending a lot of time looking to the right. The opportunity now is to look to the left,' says Robert Vonderheide, MD, DPhil, director of the University of Pennsylvania's Abramson Cancer Center and the John H. Glick Abramson Cancer Center Professor in the Perelman School of Medicine. 'Can we intercept those precursor lesions before they become cancer?'" Read more of "Can We Intercept Cancer?"
[02/21/23] Katherine Unger Baillie for Penn Today: "In the journal eLife, they report on their step-by-step process of rewiring cells. The findings—the first in the marmoset, a small monkey—open new possibilities for studying primate biology and developing novel assisted reproductive technologies like in vitro gametogenesis, a process of generating germ cells, sperm or eggs, in a laboratory dish, akin to how in vitro fertilization involves the generation of an embryo outside the human body.
"'Scientists know how to generate functional sperm and egg from induced pluripotent stem cells in mice, but mouse germ cells are very different from human germ cells,' says Kotaro Sasaki, an assistant professor at Penn Vet. 'By studying marmosets, whose biology more closely resembles ours, we can bridge the gap.'" Read more of "Rewiring blood cells"
[02/14/23] Christina Hernandez Sherwood for Penn Medicine News: "The disparities are stark. Black women are three times more likely to die from a pregnancy-related cause than white women in the United States, which has the highest maternal mortality rate of any developed country.
"For years, the University of Pennsylvania has been a leader in working to change that pattern — advancing the field of maternal health equity through widely-cited clinical research, innovative technology, and more. Now, a key national partnership will broaden Penn's reach, making it a focal point for maternal health equity research and racial disparity solutions.
"In January, the University of Pennsylvania became home to the inaugural March of Dimes Research Center for Advancing Maternal Health Equity. Under the leadership of Elizabeth Howell, MD, MPP, chair of the Department of Obstetrics and Gynecology in the Perelman School of Medicine, the center will leverage Penn's research, technology, and partnerships to address racial disparities in maternal health outcomes — both deaths and serious medical complications — in the United States."

[01/05/23] Frank Otto for Penn Medicine News: "Another project led by Rebecca Hamm, MD, an assistant professor of Obstetrics and Gynecology, will implement a nudge to prompt the use of an 'evidence-based calculator' that could provide decision support to clinicians. For patients at the low end of the risk spectrum, use of this calculator can empower the patient and their clinicians to achieve vaginal deliveries and avoid unnecessary c-sections. At the high end of the risk spectrum, the calculator could enable a faster decision for proceeding with c-section and prevent complications." Read more of "Making Life Easier for Clinicians"

[11/21/22] Katherine Unger Baillie for Penn Today: "'This is a proof-of-principle that we can create a system grown in a dish that functions nearly identically to a human adrenal gland in the early stages of development,' says Kotaro Sasaki, senior author and an assistant professor at Penn Vet. 'A platform like this could be used to better understand the genetics of adrenal insufficiency and even for drug screening to identify better therapies for people with these disorders.'
"Sasaki says his team's aim was to use human inducible pluripotent stem cells (iPSCs), which can give rise to a myriad of different cell types, to mimic the stages of normal human adrenal development. During this process, the cells would get directed to take on the characteristics of the adrenal gland." Read more of "Recreating the adrenal gland"
[11/15/22] Scott Harris for Penn Medicine News: "'With this small, quarter-sized device, we took multiple cell types that are involved in early implantation and then assessed them in the same physiological arrangement that you see in vivo,' said Monica Mainigi, MD, the study’s co-senior author and an associate professor of Obstetrics and Gynecology and the fellowship director of Reproductive Endocrinology and Infertility at the Hospital of the University of Pennsylvania. 'We wanted to study how the uterus controls embryo implantation, but the current models are insufficient. This process begins very early in pregnancy before most women have even taken a pregnancy test. So, we don't have a lot of ways to study this in humans.'" Read more of "'Organ-on-a-Chip' Device"
[11/10/22] Meagan Raeke for Penn Medicine News: "These mutations strongly predispose women to breast and ovarian cancers, and these cancers have a high risk of recurrence after initial treatment. In the new study, published this week in Nature Communications, the researchers compared a large set of tumors from patients with primary and recurrent BRCA1/2 mutation-associated breast and ovarian cancers, and found multiple features associated with recurrence, including features that would be expected to improve tumors' ability to repair treatment-caused DNA damage.
"'These results suggest key biological features of therapy-resistant recurrences, which point to new possibilities for treating BRCA1/2-mutation cancers,' said the study’s senior author Katherine Nathanson, MD , the Pearl Basser Professor for BRCA-Related Research in Penn's Perelman School of Medicine, Deputy Director of the Abramson Cancer Center, and Director of Genetics at the Basser Center for BRCA."

[10/10/22] Frank Otto for Penn Medicine News: "When struggling to conceive, every second that ticks by feels precious. That makes it easy to get discouraged: 65 percent of those who seek fertility care eventually discontinue treatment, the majority due to stress. That’s why Penn Medicine recently instituted a telemedicine-driven program aimed at seeing patients more quickly and starting treatments sooner. The program, Fast Track to Fertility, cut the time between when patients initially reached out for help to when they received their first treatment by half—getting them on the path to parenthood roughly a month and a half sooner, according to research published in NEJM Catalyst by researchers at the Perelman School of Medicine at the University of Pennsylvania."

[10/05/22] Michele W. Berger for Penn Today: "April 2020 was a confusing and uncertain time. Just weeks after the emergence of the first U.S. cases of COVID-19, guidance on the new virus was changing daily. 'Only grocery stores were open. People were wiping everything down. All the playgrounds were shut,' says Penn psychologist Rebecca Waller. 'It was quite scary for everyone, but we imagined, particularly for pregnant individuals.'
"Waller and colleagues from the Perelman School of Medicine and the Children's Hospital of Philadelphia (CHOP) had recently begun working together on an interdisciplinary initiative. They called it the Intergenerational Exposome Project—IGNITE for short—and their aim was to unite traditionally siloed research areas to better understand risk factors for preterm birth and poor pregnancy outcomes."

[09/21/22] Frank Otto for Penn Medicine News: "'Genetic counselors order testing on multiple patients every day,' said the study's lead author, Katherine Nathanson, MD, the Pearl Basser Professor of BRCA-Related Research and Deputy Director of the Abramson Cancer Center at Penn. 'So if you order tests on three patients per day and return results on three patients per day – which is a very reasonable estimate– that means you save 45 minutes per day, based on what we saw. That is a big deal.'
"The average time it took a clinician to order a test for a person's genomic information – data gleaned from personal DNA – through the new process developed by the Penn researchers was two minutes. When clinicians had to go outside of the EHR, test ordering averaged eight minutes, with the longest time being 20 minutes, a 75 percent time savings." Read more of "Integrating Genetic Testing"

Penn Medicine Maternal Mortality Prevention Innovation Selected for Federal Racial Equity in Postpartum Care Program
[08/24/22] Hoag Levins for the Leonard Davis Institute of Health Economics: "It's rare for any innovation in health care delivery to achieve an overnight 80% improvement. Yet, eight years ago, that's what happened with Penn Medicine physicians Sindhu Srinivas, MD, MSCE, and Adi Hirshberg, MD, when they applied then-novel digital technologies to the control of postpartum preeclampsia complications among their OB/GYN patients at the Hospital of the University of Pennsylvania (HUP)."

She originally created the program for new parents with uncomplicated routine births wanting to go home early, an effort she pursued with a team as part of an Innovation Accelerator project with the Center for Health Care Innovation. The program’s texting service — a chatbot — allowed them to still remain connected with their care providers. To make communication easier, its automated chatbot, named Penny, used 'natural language processing,' Leitner said. 'That means patients can ask questions and receive answers in a natural way.'"

[06/22/22] Katherine Unger Baillie for Penn Today: "Unlike women, who are born with all the eggs they’ll ever have, men can continue to produce sperm throughout their adult lives. To do so, they require a constant renewal of spermatogonial stem cells, which give rise to sperm.
"This reinvigoration of stem cells depends on a newly characterized stem cell self-renewal factor called DOT1L, according to research by Jeremy Wang of the University of Pennsylvania School of Veterinary Medicine and colleagues. When mice lack DOT1L, the team showed, they fail to maintain spermatogonial stem cells, and thus, lack the ability to continuously produce sperm."

Mennuti, MD, Associate Professor in Reproductive Health, chief of Maternal Fetal Medicine, and co-director of the Pregnancy and Heart Disease Program at Penn Medicine. 'Many complications of pregnancy, such as HDP and preterm birth, are associated with increased risks later in life. We knew from epidemiologic data that patients who have had high blood pressure in pregnancy (or HDP) are at higher risk of heart disease later in life, but it had not been evaluated to this extent at the 10-year mark. We looked at this question in a group of people, largely Black women, who are at a higher risk of both HDP and heart disease.'" Read more of "High Blood Pressure Conditions During Pregnancy"
[04/20/22] Brandon Lausch for Penn Medicine News: "The dangers posed by these and similar conditions, known together as hypertensive disorders of pregnancy (HDP), are better understood than ever. Nevertheless, successful strategies for improving lifestyle factors like physical activity in this population have remained elusive. Gamification has been successfully used in various healthcare disciplines and beyond, but this is the first time it has been tested in women with HDPs. With that in mind, Lewey and the study’s senior author, Lisa Levine, MD, the Michael T.

FDA Approves “Glowing Tumor” Imaging Drug to Better Identify Ovarian Cancer Cells Using Approach Pioneered by Surgeons at the University of Pennsylvania
[11/30/21] Caren Begun for Penn Medicine News: "'Lighting up cancer, which helps to identify lesions that may be difficult to find—especially in the presence of scar tissue or other organ damage—enables more complete identification and surgical removal of cancer that could have otherwise been missed,' said Janos L. Tanyi, MD, PhD, an Associate Professor of Obstetrics and Gynecology in the Perelman School of Medicine at Penn and Principal Investigator at Penn's clinical trial site for Phase 2 and Phase 3 studies.

[07/22/21] Alex Gardner for Penn Medicine News: "Clinicians should not take race into account when diagnosing anemia in pregnant patients and pursuing interventions, according to new research from the Perelman School of Medicine at the University of Pennsylvania. While national guidelines define anemia (low iron levels) differently depending on whether a pregnant patient is Black because lower iron levels are more common among Black women, the researchers found Black patients with no diagnosed anemia during pregnancy were more likely to have anemia at time of delivery compared to non-Black patients. The results suggest that, in order to intervene early and decrease risk of poor health outcomes and a need for blood transfusions during delivery, Black and non-Black pregnant patients should be treated with the same thresholds when evaluated for anemia. The findings are published in the journal Obstetrics & Gynecology." Read more of "Using Race to Diagnose Anemia"

About five percent of both Black and white women have a genetic mutation that increases their risk of breast cancer.
"'The findings challenge past, smaller studies that found Black women face a greater genetic risk and the suggestion that race should be an independent factor when considering genetic testing,' said first author Susan Domchek, MD, executive director of the Basser Center for BRCA.

Mutations Commonly Linked to Breast Cancer Found to Pose No Increased Risk, Population Study Reveals
[01/20/21] Steve Graff for Penn Medicine News: "Several genetic mutations previously linked to breast cancer and included on commercial genetic tests, including direct-to-consumer tests, were found not to increase a woman’s risk of disease, according to a population study of more than 64,000 women published online today in the New England Journal of Medicine from several institutions, including Penn Medicine. The findings show that risks associated with mutations for women in the general population are often lower than previous estimates, and, importantly, provide new insights informing the debate over whom should be recommended for genetic testing."
