Leading Medicare: Q&A With Medicare Director Meena Seshamani
Meena Seshamani, MD, PhD, Director, Center for Medicare at Centers for Medicare & Medicaid Services and JAMA Associate Editor Karen Joynt Maddox, MD, discuss Dr Seshamani’s recently established role as director of Center for Medicare.
COVID-19 Vaccination During Pregnancy: Maternal Protection and Neonatal Immunity
For COVID-19, pregnant individuals remain one of the least vaccinated groups in the US. This is concerning given the increased risks of pregnancy complications due to COVID-19, including hospitalization and preterm birth, which are preventable with vaccination. In addition, a newborn's immune system is not fully developed, and some vaccines received during pregnancy can protect an infant in early life through passive immunity via placental transfer or through breast milk. Boosting immunity in newborns through passive transfer of antibodies has received increased attention in light of the COVID-19 pandemic.
Caffeine and the Human Body
Caffeine is estimated to be the most widely used legal psychoactive drug in the world. About 85% of US adults consume caffeine daily, averaging about 135 mg per day, or about a 12 fl oz cup of coffee. This video explores what caffeine is and some ways it affects our bodies.
Screening for Prediabetes
In August 2021 JAMA published the US Preventive Services Task Force’s updated Recommendation Statement on Screening for Prediabetes and Type 2 Diabetes. The updated guidance differs from the 2015 recommendation in that the age to begin screening is lowered from 40 to 35, and it uses the term “prediabetes” to identify individuals who are at high risk for developing diabetes. This video will discuss the evidence for screening for prediabetes and the updated USPSTF guidelines.

Coronal and Cross-sectional Views of the Mechanism of Retinal Displacement Following Pars Plana Vitrectomy
This video shows coronal and cross-sectional views of the suggested mechanism for retinal displacement following pars plana vitrectomy. The small amount of residual subretinal fluid that remains at the completion of surgery along with the use of an intraocular gas tamponade may result in the displacement of subretinal fluid under the influence of the buoyant force of the gas bubble and gravity in a direction related to postoperative positioning. This generally results in fluid flowing from posterior to anterior and often inferiorly with a corresponding stretch of retina. Click https://ja.ma/39XOdue to read the article.
Mechanism of Retinal Displacement Following Pars Plana Vitrectomy
This video demonstrates the suggested mechanism for retinal displacement following pars plana vitrectomy. Typically in a vitrectomy, the small amount of residual subretinal fluid that remains at the completion of surgery along with the use of an intraocular gas tamponade may result in the displacement of subretinal fluid under the influence of the buoyant force of the gas bubble and gravity in a direction related to postoperative positioning. This generally results in fluid flowing from posterior to anterior and often inferiorly, resulting in a corresponding stretch of the retina and misalignment of the photoreceptors with the retinal pigment epithelium compared with their original preretinal detachment location.

Mechanism of Retinal Reattachment Following Pneumatic Retinopexy
This video demonstrates the mechanism of subretinal fluid reabsorption without retinal displacement following pneumatic retinopexy with a steam-rolling maneuver. The small gas bubble in the vitreous cavity exerts minimum buoyant force on the retina, and therefore, there is less forceful flow of subretinal fluid under the retina, allowing the retinal pigment epithelium pump to reabsorb the subretinal fluid and the photoreceptors to interdigitate into a more natural position.

Deep Generative Models for Synthetic Retinal Image Generation
Deep learning algorithms were able to generate retinal images with AMD that retinal specialists were unable to distinguish from real patient images. The synthetic images could be used for education and to train machines to read patient retinal images. Which of the images below is real, and which fake? To learn more and for the correct answer, see https://jamanetwork.com/journals/jamaophthalmology/fullarticle/2720489
