Diagnostic Accuracy of an Integrated AI Tool to Estimate Gestational Age From Blind Ultrasound Sweeps.
Accurate assessment of gestational age (GA) is essential to good pregnancy care but often requires ultrasonography, which may not be available in low-resource settings. This study developed a deep learning artificial intelligence (AI) model to estimate GA from blind ultrasonography sweeps and incorporated it into the software of a low-cost, battery-powered device. ⋯ Between 14 and 27 weeks' gestation, novice users with no prior training in ultrasonography estimated GA as accurately with the low-cost, point-of-care AI tool as credentialed sonographers performing standard biometry on high-specification machines. These findings have immediate implications for obstetrical care in low-resource settings, advancing the World Health Organization goal of ultrasonography estimation of GA for all pregnant people.

Hospitals are hot zones of the US gun injury epidemic. To shelter these facilities from the dangers of gun violence, state legislatures have enacted laws to reduce the carrying of firearms on hospital premises. However, these efforts currently face serious Second Amendment challenges in federal courts. The ongoing legal battles, which have wide-ranging implications for patient and clinician safety as well as public health generally, are setting the stage for a Supreme Court case that may decide the fate of firearm regulations in US hospitals. A permissible pathway for advancing sensible gun regulation in hospitals is urgently needed. ⋯ The Supreme Court's interpretation of the Second Amendment right to bear arms is threatening democratically enacted laws seeking to shelter hospitals from firearm violence. However, it is clear that hospitals and other health care settings are a sensitive place with compelling historical analogies. Policymakers' strategic deployment of the sensitive places designation, along with its rightful judicial recognition in the hospital setting, are critical to upholding laws that protect health care facilities, patients, and professionals from firearm violence-a conclusion consistent with the US Constitution, history, medical ethics, and common sense.
