Background: The impact of social isolation on social cognition is not entirely clear.
Objective: The aim of the study is to investigate the association between social isolation and social cognition.
Methods: In a population-based sample of 83 individuals aged 50+ years without dementia, we assessed the relationship between social isolation (measured by the Lubben Social Network Scale - LSNS-6) and performance on emotional recognition (measured by the Emotion Recognition Task (ERT)) and on Theory of Mind (ToM) abilities (measured by the Reading the Mind in the Eyes Test (RMET)), two core aspects of social cognition.
The field of bioinspired iontronics, bridging electronic devices and ionic systems, has multiple biological applications. Carbon-based ultracapacitive devices hold promise for controlling bioactive ions via electric double layers due to their high-surface-area and biocompatible porous carbon electrodes. However, the interplay between complex bioactive ions and porous carbons remains unclear due to the variety of structures of bioactive ions present in biological systems.

These processes are simpler and more cost-effective than the industrially used electron beam lithography because of their purely mechanical process step. For the investigation of material dependence, platinum as well as carbon electrodes were fabricated.

- People with dementia often lack awareness of their social functioning abilities, which can lead to negative outcomes for both them and their caregivers.
- This study examined how this awareness relates to the severity of dementia in individuals over 65 from Germany, Japan, and the UK using the Social Functioning in Dementia scale.
- Findings showed that while patients and caregivers agreed on some aspects of social functioning, patients tended to overestimate their communication and sensitivity skills compared to their caregivers, highlighting the need for better understanding and support for families.
Immunogenicity, reactogenicity, and safety of a second booster with BNT162b2 or full-dose mRNA-1273: A randomized VACCELERATE trial in adults aged ≥75 years (EU-COVAT-1-AGED Part B).

Objectives: To assess the safety and immunogenicity of a fourth vaccination (second booster) in individuals aged ≥75 years.
Methods: Participants were randomized to BNT162b2 (Comirnaty, 30 µg) or messenger RNA (mRNA)-1273 (Spikevax, 100 µg). The primary end point was the rate of two-fold antibody titer increase 14 days after vaccination, targeting the receptor binding domain (RBD) region of wild-type SARS-CoV-2.
