Topiramate in early pregnancy increases risk of oral clefts

A new study by Brigham and Women's Hospital investigators found that taking topiramate in early pregnancy increases the risk of oral clefts, particularly at high doses. The risk is approximately three times higher for women who took topiramate compared to those who did not take anti-epileptic medications.

Uncovering molecular targets for childhood cancer therapeutics

Researchers found that nearly half of neuroblastoma samples had gene loss or imbalance in DNA damage response-associated molecules located on chromosome 11. PARP inhibitors, commonly used for ovarian cancer treatment, showed promise as a potential therapeutic approach for targeting childhood cancer.

State Medicaid expansions led to more prenatal care for low-income mothers

The study found that expanded Medicaid coverage led to a 2.3% decrease in uninsured rates among pregnant women who already had a child, and a 7.9% decrease in the number of uninsured mothers during pregnancy. Additionally, lower-educated mothers were 1.7% more likely to receive adequate prenatal care due to the expansions.

Ophthalmologists report increased use of electronic health records but decreased productivity as a result

A survey of 348 US ophthalmologists found that EHR adoption has more than doubled since 2011 to 72 percent. Despite this growth, most ophthalmologists reported a decrease in productivity as a result of EHR use. This study emphasizes the need for improving the efficiency and usability of EHR systems to mitigate negative perceptions.

Cancer overrides the circadian clock to survive

Researchers at the Medical University of South Carolina found that cancer cells use the unfolded protein response to alter their circadian rhythm, contributing to tumor growth. Misfolded proteins cause disruptions in this natural clockwork, allowing cancer cells to survive conditions that would kill normal cells.
