Obstetrics & Gynecology

News and Events

Programs and providers of Obstetrics and Gynecology at Weill Cornell Medicine are often the focus of news stories and features appearing in major national media. We invite you to review some stories that typify the breakthrough accomplishments of our remarkable team and highlight the impact our care has had on patient’s lives.

Immune Complex Shaves Stem Cells to Protect against Cancer

A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, according to a preclinical study by Weill Cornell Medicine investigators.

The study, published Jan. 2 in Nature Immunology, may lead to therapies that target the earliest stages of cancer. The findings bolster the idea that the inflammasome has a dual role—it promotes inflammation associated with poor outcomes in late cancer stages, but early on, it can help prevent cells from becoming cancerous in the first place.

Medicare Rules May Reduce Prescription Steering

Medicare prescription drug access

Weill Cornell Medicine researchers have found that pharmacy benefit managers (PBMs)—organizations that negotiate access to medicines for most patients in the United States—steer patients to use their own pharmacies. However, these pharmacies appear less used in Medicare than in other market segments. These PBMs are part of integrated health care conglomerates that own insurance companies and pharmacies, which may create conflicts of interest.

The study, published Jan. 10 in JAMA Health Forum, found that in 2021 a third of all Medicare Part D pharmacy spending and almost 40% of specialty drug spending within Medicare Part D was through pharmacies owned by the four largest PBMs: CVS, UnitedHealth Group, Cigna or Humana. However, this represents a far lower market share in Medicare than the nearly two-thirds national market share noted by a Federal Trade Commission’s 2024 report. The findings may help guide future policy decisions on how these entities are regulated.

Innovators Encourage Scientists and Physicians to Dive into Technology Commercialization

When Dr. Tamatha Fenster received a call from a young patient requesting a refill on her Oxycodone for pelvic pain, she was faced with a dilemma: letting the patient remain in pain or refill a prescription and perpetuate an opioid dependency.

With few other pain-relief options, she refilled the prescription. “I had to think of an alternative for pelvic pain for women,” said Dr. Fenster, assistant professor of clinical obstetrics and gynecology at Weill Cornell Medicine and an obstetrician and gynecologist at NewYork-Presbyterian/Weill Cornell Medical Center. And she did just that.

Dr. Fenster, along with other researchers and physicians, recounted their technology development and commercialization journeys at the annual Dean’s Symposium on Innovation and Entrepreneurship, hosted by Enterprise Innovation Dec. 18 in Uris Auditorium. In its eighth year, the symposium celebrates innovation and Weill Cornell Medicine’s entrepreneurial spirit, while encouraging and motivating the next generation of innovators, inventors and entrepreneurs.
