Variability in Vaccine Response and Trajectory in Early Childhood and Association with Demographic Variables, Antibiotic Exposure and Infection Proneness.

Introduction: We sought to explore the variability of antibody responses to multiple vaccines during early life in individual children, assess the trajectory of each child longitudinally, determine the associations of demographic variables and antibiotic exposures with vaccine-induced immunity, and link vaccine responsiveness to infection proneness.

Methods: In 357 prospectively-recruited children, age six through 36 months, antibody levels to 13 routine vaccine antigens were measured in sera at multiple time points and normalized to their respective protective thresholds to categorize children into four groups: very low, low, normal, and high vaccine responder. Demographic variables and frequency of antibiotic exposure data were collected.

Examining the Feasibility and Acceptability of Identifying Signs of Social Anxiety, in University Students Aged 18-25, While Watching 360° Immersive Films.

Timely, accurate assessment and treatment for social anxiety disorder (SAD) in young people is crucial. There is potential for the adoption of tailored virtual reality interventions for a complementary diagnostic tool using heart rate monitoring as a response indicator. This study examined the feasibility and acceptability of this concept by exposing healthy individuals, aged 18-25, to developed 360° immersive films while collecting heart rate sensor data.

3D-Printable Elastomers for Real-Time Autonomous Self-Healing in Soft Devices.

Photocurable self-healing elastomers are promising candidates for producing complex soft devices that can mend damage. However, the practicality of these materials is limited by reliance on external stimuli, custom synthesis, manual realignment, and multihour healing cycles. This paper introduces a tough 3D-printable hybrid acrylate/thiol-ene elastomer (prepared with commercially available precursors) that exhibits nearly instantaneous damage repair in the absence of external stimuli.

Polygenic score distribution differences across European ancestry populations: implications for breast cancer risk prediction.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.
