Researchers at Iowa State University are using stem cells from a person's blood to treat certain types of cancer. Their work could mean the end of bone-marrow transplants.

The research boils down to taking the next step in personalized medicine.

Researchers draw blood from a patient's body, grow new stem cells in the lab - then use blood containing the new stem cells to attack blood diseases, like leukemia, in that patient.

ISU Assistant Professor of Genetics, Development and Cell Biology - Raquel Espin Palazon - said this research could end the need for bone-marrow transplants, which can be lethal 60% of the time because of what's known as "graft-versus-host disease."

"It's not them, obviously because it came from another person," said Espin Palazon, "and then, it's just going to attack the tissues of the patient. "

Federal data show right now, there are 18,000 people in the U.S. suffering from blood diseases which can only be treated with bone-marrow transplants.

She added that it's incredibly complex to get a handle on blood-borne diseases, mostly because the body generates as many as 200 billion new red blood cells every day.

So, Espin Palazon said researchers are turning to the petri dish to create stem cells in the 'embryonic' condition - their natural state, before the patient became sick - and using them to treat disease.

"Naturally, how can we recreate that in the dish," said Espin Palazon, "so that we can make blood stem cells from patients?"

Espin Palazon said researchers will eventually be able to turn on critical "switches" in the stem cells that could make them even more effective in treating disease.

Despite uncertainty about Medicaid funding in Congress, Tennessee is moving ahead to help improve people's health outcomes with a program for community health workers.

Tennessee's Medicaid program, TennCare, is partnering with the Tennessee Community Health Worker Association to offer an accreditation program to promote best practices for training and supporting the workforce.

Nikayla Boyd, executive director of the association, said community health workers link people to care and promote healthy habits. She noted the pilot accreditation program is underway, with a full launch expected by 2027.

"In addition to CHWs having individual certification, we are also accrediting the actual CHW program," Boyd explained. "Accrediting that program, that organization, that employer."

TennCare will fund grants for up to 14 organizations to complete the accreditation process. There are about 600 community health workers in the state, according to the U.S. Bureau of Labor Statistics, but Boyd argued more are needed.

Boyd pointed out they partner with the National Committee for Quality Assurance to design the accreditation programs. Some are centered on specific diseases, while others primarily address the social determinants of health.

"To date, we have six programs in Tennessee that have been accredited," Boyd outlined. "Two at Methodist Le Bonheur Community Outreach, two at Siloam Health, one at Regional One Health and then, another at the Mental Health Cooperative."

Boyd added an organization must meet seven standards in order to be accredited. For those working with community health workers, they include the full scope of training from recruitment to evaluations, support and supervision.

Republican lawmakers are considering billions of dollars in cuts to Medicaid. But a new report finds those spending cuts might impact health-care coverage for thousands of Maryland military families.

The report by the Georgetown Center for Children and Families finds more than 850,000 people enrolled in Medicaid have military health insurance, known as TRICARE, as their primary coverage. One in 10 children of service members with TRICARE is also enrolled in Medicaid.

Joan Alker, executive director of the Georgetown University Center for Children and Families, said Medicaid is important for service members with children who require more intensive health care.

"The TRICARE benefit package just isn't enough, so Medicaid is making TRICARE work for those families by covering the high cost of services and some benefits that those children otherwise would not have access to," Alker explained.

Republicans in Congress are trying to reel in what they view as out-of-control spending by $2 trillion in the next budget. But cuts to Medicaid are not universally agreed upon among Republican lawmakers.

Medicaid also serves 40% of children in the U.S. with a benefit that allows them to receive preventive and ameliorative care. That benefit began after a military report in the 1960s found young men were not qualified for military service in Vietnam because of preventive medical issues during their childhoods.

Retired Army Brigadier General George Schwartz said Medicaid cuts could have a negative impact on recruiting numbers as well. If troops lack proper coverage for their families, he thinks they may seek other career paths that can provide that coverage.

"As those young people reach the age where they're eligible for military service, the military is competing with private industry and all sorts of organizations for these young people. From a mission readiness point, this is a matter of national security," Schwartz contended.

Maryland is home to more than 100,000 active-duty service members and more than 35,000 military-connected children in the state.

With Mother's Day coming up, some Pennsylvania lawmakers are backing a set of bills that could help improve maternal health.

The Black Maternal Health Caucus introduced the updated "PA Momnibus 2.0" package in April, focused on tackling disparities in maternal health care by improving access to services.

Black women in the state are nearly twice as likely to die from childbirth complications. Rep. La'Tasha D. Mayes, D-Allegheny County, said 93% of maternal deaths are preventable.

"All the bills are for all moms, and because we know when we fix and address and take on maternal mortality and morbidity for Black moms, we solve it for every mom and birthing person in the Commonwealth," she explained.

The nine-bill package builds upon a 2024 "Momnibus" introduced by Mayes and Reps. Morgan Cephas and Gina Curry, both Republicans. Mayes said the caucus is working towards moving the bills toward votes, and then action in the Senate.

Two of the measures would expand access to blood pressure monitors and ensure they are covered through private insurance and Medicaid. Mayes added another measure would expand the reach of midwives, who provide care throughout pregnancy and childbirth, as well as postpartum.

"The Midwifery Practice Innovation bill that's going to help us advance midwifery as an occupation in this commonwealth, because it's very challenging to become a midwife, as well as be able to practice fully in a way that can serve moms," she continued.

The "Momnibus" also includes supports for nursing mothers, and invests in a Maternal and Newborn Supply Kit program, and maternal-health deserts. Mayes says more than 12% of women have no birthing facility within 30 minutes of their home, and Black women are three times more likely to die during or after birth compared with other women.
