Electroencephalography (EEG) is crucial for diagnosing neurological disorders and facilitating brain-computer interfaces. Traditional EEG setups with wet gels and cumbersome cables are labor intensive, uncomfortable, and degrade over time. Dry, skin-conformable e-tattoos offer a comfortable and user-friendly alternative but struggle with hairy scalps. To tackle this problem, we introduce non-contact digital printing of e-tattoos directly on the hairy scalp. Biocompatible inks are crafted for low-impedance electrodes and high-conductivity interconnects.

Cancer catalytic therapy leveraging biocompatible nanocatalysts represents an emerging approach for cancer treatment. However, existing nanocatalysts often face issues such as suboptimal catalytic efficiency and limited therapeutic efficacy. Here, we present a self-powered electromodulative system designed for augmenting cancer catalytic therapy through the integration of an abiotic-biotic hybrid with a wearable self-powered triboelectric device.

Objective: To investigate whether social vulnerability is associated with the direct and indirect burdens of urinary incontinence (UI). UI affects over half of all adult women living in the United States and can affect quality of life. While individual-level social determinants of health have been associated with urologic disease, the effect of community-level factors is poorly characterized. Community-level social vulnerability as measured using the social vulnerability index (SVI) from census-level data has been associated with worse health outcomes.

Background: Despite extensive efforts to standardize definitions of obesity, clinical practices of diagnosing obesity vary widely. This study examined (1) discrepancies between biometric body mass index (BMI) measures of obesity and documented diagnoses of obesity in patient electronic health records (EHRs) and (2) how these discrepancies vary by patient gender and race and ethnicity from an intersectional lens. Methods: Observational study of 383,380 participants in the National Institutes of Health All of Us Research Program dataset.

Background: Population-based penetrance studies of breast cancer gene 1/2 (BRCA1/2) pathogenic or likely pathogenic (P/LP) variants in the Eastern Chinese population are currently lacking; thus, we aimed to investigate the penetrance of breast cancer and other malignant tumors among BRCA1/2 P/LP variant carriers using a population-based breast cancer cohort from communities in Eastern China.
