National Trends in Infant Mortality in the U.S. After Dobbs
New study compared infant mortality rates for the 18 months following the Dobbs decision against historical trends. Scientists found infant death rates were higher than usual after the Dobbs decision, and of the infant deaths, 80% were attributed to birth defects and anomalies. This means that more women have to carry these gestations and give birth, knowing their child is likely going to die shortly after birth. Full Access: JAMA
Spontaneous Headshake After a Kinematic Event (SHAAKE): Evaluating the Utility of a Potential New Sign in the Diagnosis of Concussion
A cross-sectional survey study of 347 athletes identified whether SHAAKE occurred, the reasons underlying SHAAKEs and its utility for self-reported concussion. Across all sports, SHAAKE had a sensitivity of 49.6% and positive predictive value 72.4% for diagnosing concussion. In football players, SHAAKE had a sensitivity of 52.3%, estimated specificity of 99.9%, positive predictive value of 91.9% and estimated negative predictive value of 99.5% for diagnosing self-reported concussion. These results demonstrate that nearly three-quarters of athletes reported a SHAAKE associated with a self-reported concussion, which supports the potential for SHAAKE to be used as a concussion screening tool.

Open-Label Placebo Injection for Chronic Back Pain with Functional Neuroimaging
In this randomized clinical trial, an open-label subcutaneous placebo (saline) injection led to significant improvements in pain intensity, mood and sleep at 1-month posttreatment compared with usual care. The placebo treatment also led to reduced somatomotor activity and increased medial prefrontal activity during evoked back pain and to increased medial prefrontal-brainstem functional connectivity during spontaneous pain.
