Doctors have long emphasized the importance of maintaining a healthy body weight and getting enough sleep, but in our time-limited lives, we often have to choose between spending time exercising, preparing healthy meals, and getting sufficient shuteye. And the number of hours in the day may not be the only thing that pits weight loss against sleep. A recent IRP study suggests that young women who are not obese get poorer sleep when they change their diets in order to lose weight.

The women in our lives deserve flowers and thanks on Mother’s Day, but they also deserve attention to their well-being. This past Sunday, May 12, marked the start of Women’s Health Week, a time to reflect on the decisions women make to look after their own health.

For instance, breast cancer treatments are something no woman wants to think about, but every year about 240,000 newly diagnosed women in the U.S. face high-stakes decisions about what medical interventions to pursue. IRP Stadtman investigator Jinani Jayasekera, Ph.D., and her colleagues in the IRP’s Health Equity and Decision Sciences (HEADS) lab develop software-based clinical decision-making tools to help women and their doctors assess and address their health risks when choosing treatments.

Delivering on Maternal Health

IRP’s Katherine Grantz Develops Tools to Predict Pregnancy Complications

Advancements in medicine have reduced the risk of childbearing dramatically, but rates of maternal death have been creeping up in recent years. The reasons are varied. Older first-time parents, greater health concerns like obesity and hypertension, and lack of access to maternity care are important factors.

In observance of Maternal Health Awareness Day on January 23, we spoke with Katherine Grantz, M.D., a maternal-fetal medicine specialist and senior investigator at the Eunice Kennedy Shriver National Institute on Child Health and Human Development (NICHD). She is trying to improve health for pregnant people and their babies experiencing complications like gestational diabetes and hypertension, as well as reduce preterm deliveries and unnecessary C-sections.

Cooking Up a Recipe for Healthier Eating

IRP’s Tonja Nansel Probes the Hidden Forces Behind Our Food Choices

As legendary chef James Beard once said, “Food is our common ground, a universal experience.” Beyond a basic need to stay alive and obtain healthful nutrients, food is a source of pleasure, a reflection of culture, and a link to others. However, for many of us, food is also a challenge. There’s the food we love and the food that’s good for us, and the two aren’t always the same.

As we celebrate World Food Day on October 16, we spoke with IRP senior investigator Tonja Nansel, Ph.D., who is seeking explanations for the nutritional choices we make.

“The dietary quality of the U.S. population is well below recommended guidelines, and that’s the case regardless of income, education, and background,” Dr. Nansel says. “Simply put, we’re all eating badly.”

Symposium Celebrates Award-Winning Female Scientists

Three Young Women Honored at Annual Event

Dr. Brittany Lord

There’s no doubt that science flourishes when it welcomes individuals with different backgrounds and perspectives. In pursuit of that goal, NIH has put considerable effort into closing the gender gap in the biomedical sciences, a field in which men significantly outnumber women, especially as the heads of labs and in leadership positions. Those efforts have so far yielded promising progress, with the proportion of women in IRP senior investigator positions increasing from 22 percent at the end of fiscal year 2016 to 27 percent at the end of fiscal year 2022. Over that same time period, women went from comprising 38 percent of IRP tenure-track investigators to 44 percent.

Part of what makes the IRP a welcoming place for female scientists is the NIH Women Scientists Advisors (WSA), a group of IRP scientists elected to represent the interests of women in the IRP. Once per year, the WSA selects a few female postdoctoral fellows or graduate students conducting research at NIH as WSA Scholars. At a symposium on April 13 honoring the achievements of this year’s Scholars, the awardees presented their efforts to learn more about a devastating childhood neurological condition, decrease health disparities in breast cancer, and use stem cells to investigate the roots of a nerve-destroying disorder. Read on to learn more about this year’s WSA Scholars and the important work they’re doing in their IRP labs.

Moms’ Caffeine Consumption May Affect Babies’ Brains

Findings Could Explain Why Caffeine Exposure In-Utero Increases Kids’ Risk for Obesity

Between books, the media, and well-meaning friends and relatives, new parents are inundated with advice about how to set their kids up for a happy and healthy future. However, what parents do before their children are even born can also have a huge impact on how they turn out. For instance, new IRP research suggests that a pregnant woman’s caffeine consumption can rewire her baby’s brain in ways that put the child at increased risk for obesity later in life.

Researchers Delve Into New Moms’ Depression

Researchers Delve Into New Moms’ Depression

Fresh off celebrating Mother’s Day this past Sunday, as well as Women’s Health Week this week, it’s important to acknowledge that being a new mom isn’t easy. As joyful and exciting as a new baby might be, it can be exhausting and worrisome, too. Many new moms experience some level of baby blues, but for some women, those blues can take a downward turn into symptoms of more serious depression.

Approximately one out of every eight women in the U.S. experiences symptoms of postpartum depression, according to the U.S. Centers for Disease Control and Prevention. What’s more, a recent study led by IRP staff scientist Diane Putnick, Ph.D., has shown that the course of postpartum depression can differ significantly among women. The study of nearly 5,000 women not only showed that 25 percent of them experienced symptoms of postpartum depression, but it also found that depression symptoms followed several different patterns and could persist for at least three years after giving birth. Understanding these different patterns of symptoms and some of the risk factors associated with them may help physicians recognize and monitor mothers who are at higher risk for persistent depression.

Postdoc Profile: Finding the Narrative Behind the Numbers

Dr. Shameka Poetry Thomas Documents Black Women’s Experiences With Race and Racism

The numbers are clear: Black women are three to four times more likely to die from pregnancy-related causes than White women in the United States. However, the reasons why are less clear. By listening to patient’s stories, IRP postdoctoral fellow Shameka Thomas, Ph.D. hopes to pinpoint potential explanations for this racial health disparity. 

“We are losing mothers and children because we are simply not listening,” Dr. Thomas says.

Trained as a medical sociologist at the University of Miami, Dr. Thomas has devoted her career to documenting the lived experiences of patients of color, particularly women, who are perceived as Black. Dr. Thomas contextualizes patient’s narratives within a framework of ‘street race,’ which refers to how a person’s racial identity is perceived by others, regardless of their self-reported racial identity. Examining the influence of street race on women’s healthcare experiences, she explains, allows researchers to determine how health disparities are influenced by “how others see you.”

Three-Minute Talks Pit Researchers Against the Clock

IRP Scientists Keep it Short and Sweet in Competition’s Final Round

Science is so closely associated with long, jargon-laden lectures that scientists like Neil deGrasse Tyson and the IRP’s own Anthony Fauci have become celebrities for their ability to explain complex scientific concepts in a succinct and understandable way. On June 25, 17 postbacs, graduate students, and postdocs from across NIH showcased their own communication chops in the final round of the IRP’s annual Three-Minute Talks (TmT) competition.

AI Tools Provide Picture of Cervical Health

Artificial Intelligence Simplifies Cervical Cancer Screening

Even though cervical cancer is considered one of the most preventable forms of cancer, it remains a serious and deadly scourge for many across the world. A computer algorithm designed to quickly and easily identify pre-cancerous changes using a regular smartphone may change that.

“The point of everything that we do and have done in the last 40 years is to understand something deeply so that we can invent simple tools to use,” says IRP senior investigator, Mark Schiffman, M.D., M.P.H. To that end, he and collaborators in the National Cancer Institute (NCI) and the National Library of Medicine (NLM), in collaboration with the Global Health Labs and Unitaid, developed and are now testing a machine learning-based approach to screening for cervical cancer, with promising results.
