Behavior science in the evolving world of digital health: considerations on anticipated opportunities and challenges.

Digital health promises to increase intervention reach and effectiveness for a range of behavioral health outcomes. Behavioral scientists have a unique opportunity to infuse their expertise in all phases of a digital health intervention, from design to implementation. The aim of this study was to assess behavioral scientists' interests and needs with respect to digital health endeavors, as well as gather expert insight into the role of behavioral science in the evolution of digital health.

Skeletal muscle atrophy in bioengineered skeletal muscle: a new model system.

Skeletal muscle atrophy has been well characterized in various animal models, and while certain pathways that lead to disuse atrophy and its associated functional deficits have been well studied, available drugs to counteract these deficiencies are limited. An ex vivo tissue-engineered skeletal muscle offers a unique opportunity to study skeletal muscle physiology in a controlled in vitro setting. Primary mouse myoblasts isolated from adult muscle were tissue engineered into bioartificial muscles (BAMs) containing hundreds of aligned postmitotic muscle fibers expressing sarcomeric proteins.

Family Sources of Sexual Health Information, Primary Messages, and Sexual Behavior of At-Risk, Urban Adolescents.

Background: Sources of sexual health information exert strong influence on adolescents' sexual behavior.

Purpose: The current study was undertaken to understand how family serve as sexual information sources, the messages adolescents recall from family, and how family learning experiences affect sexual behavior among at-risk adolescents.

Methods: Individual interviews were conducted with 69 teens, ages 15-18 years, from an alternative high school and a juvenile correctional facility to capture adolescents' early sexual health learning experiences involving family and evaluate their association with teens' recent sexual behavior.

Meta-analysis of the association between cigarette smoking and incidence of Hodgkin's Lymphoma.

Introduction: Previous studies have suggested a relationship between smoking and Hodgkin's lymphoma (HL). The main objective of this study was to evaluate this potential association with a meta-analysis of observational studies.

Patients And Methods: A literature search was undertaken through December 2010 looking for observational studies evaluating the association between smoking and HL.

Ecological momentary assessment of recommended postoperative eating and activity behaviors.

Background: Successful weight loss after bariatric surgery depends on the patient's adherence to prescribed eating and physical activity behaviors. However, few studies have assessed patients' adherence to the behavioral recommendations and most have used retrospective self-report measures. The present study is the first to use ecological momentary assessment (EMA) via a palmtop computer to assess bariatric surgery patients' eating and activity behaviors in real-time in the natural environment.

Risk perception and smoking behavior in medically ill smokers: a prospective study.

Aims: To examine the influence of risk perception on intentions to quit smoking and post-treatment abstinence.

Design: Prospective and longitudinal.

Setting: United States.
