Racial Disparities in a Teen Pregnancy Prevention Program: Abstinence-Only Versus a Comprehensive Sexuality Education Program.

Background: Despite overall declines in risky teen sexual activity, racial and ethnic disparities persist. This study compared abstinence-only and comprehensive teen pregnancy prevention (TPP) programs to explore the effects of the programs on teen sexual activity-related outcomes that may differ by race/ethnicity.

Methods: Program evaluation data were collected from 7th-grade students in comprehensive (N = 3244) and abstinence-only (N = 3172) TPP programs.

Clinical efficacy of a multilamellar cream on skin physiology and microbiome in an epidermal stress model: A controlled double-blinded study.

Introduction: Stratum corneum (SC) is essential for skin barrier function, mitigating water loss and shielding against potentially harmful substances and allergens. The SC's lipid matrix, arranged in a lamellar structure, is integral to its protective role. Our study explores the restoration effects of a multilamellar cream with an acidic pH compared to a basic placebo cream on skin physiology and its interaction with the skin microbiome after stress induction via tape stripping (TS).

Impact of multilamellar formulations on stratum corneum lipid organization and epidermal lipid barrier enhancement (Part II).

Introduction: The integrity of the stratum corneum (SC) is crucial for the skin's barrier function, protecting against environmental stressors and minimizing transepidermal water loss. Advances in skincare formulations have introduced multilamellar systems designed to emulate the SC's lipid composition and organization. This study hypothesizes that the application of a multilamellar cream will significantly impact the SC's lipid content and lamellar structure, thereby enhancing the epidermal barrier.
