Programming mechanics in knitted materials, stitch by stitch.

Knitting turns yarn, a 1D material, into a 2D fabric that is flexible, durable, and can be patterned to adopt a wide range of 3D geometries. Like other mechanical metamaterials, the elasticity of knitted fabrics is an emergent property of the local stitch topology and pattern that cannot solely be attributed to the yarn itself. Thus, knitting can be viewed as an additive manufacturing technique that allows for stitch-by-stitch programming of elastic properties and has applications in many fields ranging from soft robotics and wearable electronics to engineered tissue and architected materials.

Cardiac sympathetic denervation and mental health.

Background: Bilateral cardiac sympathetic denervation (BCSD) is a surgical treatment for refractory ventricular arrhythmias. Although the procedure has shown efficacy at reducing cardiac arrhythmias, its impact on mental health is unknown. In the current study we examined associations between the BCSD procedure and mental health.

Lessons learned from a community-academic partnership addressing adolescent pregnancy prevention in Filipino American families.

Background: Filipino Americans have more adolescent pregnancies than other Asian-Pacific Islanders (APIs). Few community-academic collaborations have addressed adolescent pregnancy prevention in this community.

Objectives: We sought to describe the lessons learned from and impact of a community-based teen pregnancy prevention program for Filipino Americans implemented by a Filipina pediatrics resident.
