Abstract Background The accumulation of age‐associated cognitive deficits can lead to Mild Cognitive Impairment (MCI) and dementia. This is a major public health issue for the modern ageing population, as it impairs health, independence overall quality life. Keeping brain active during life has been associated with an increased reserve, therefore reducing risk impairment in older age. Previous research identified potential relationship between musicality cognition. Objectives Explore...

Following the recent popularity of Large Language Models (LLMs), several attempts have been made to extend them visual domain. From having a assistant that could guide us through unfamiliar environments generative models produce images using only high-level text description, vision-language model (VLM) applications will significantly impact our relationship with technology. However, there are many challenges need be addressed improve reliability those models. While language is discrete,...

Objective and Impact Statement . We use deep learning models to classify cervix images—collected with a low-cost, portable Pocket colposcope—with biopsy-confirmed high-grade precancer cancer. boost classification performance on screened-positive population by using class-balanced loss incorporating green-light colposcopy image pairs, which come at no additional cost the provider. Introduction Because majority of 300,000 annual deaths due cervical cancer occur in countries low- or...

Abstract Background Growing evidence suggests that maternal obesity may affect the intrauterine environment and increase a child's risk of developing asthma. We aim to investigate relationship between prepregnancy childhood asthma risk. Methods Cohorts children enrolled in Kaiser Permanente Northern California integrated healthcare system were followed from birth (2005–2014) age 4 ( n = 104,467), 6 63,084), or 8 31,006) using electronic medical records.

Background: Seasonal patterns of conception may confound acute associations between birth outcomes and seasonally varying exposures. We aim to evaluate four epidemiologic designs (time-stratified case-crossover, time-series, pair-matched case-control, time-to-event) commonly used study ambient temperature preterm births. Methods: conducted simulations assuming no effect on birth. generated pseudo-birth data from the observed seasonal in United States analyzed them relation temperatures using...

The approaches by which the machine learning and clinical research communities utilize real world data (RWD), including captured in electronic health record (EHR), vary dramatically. While researchers cautiously use RWD for investigations, ML healthcare teams consume public datasets with minimal scrutiny to develop new algorithms. This study bridges this gap developing validating ML-DQA, a quality assurance framework grounded best practices. ML-DQA is applied five projects across two...

Recent work has identified substantial disparities in generated images of different geographic regions, including stereotypical depictions everyday objects like houses and cars. However, existing measures for these have been limited to either human evaluations, which are time-consuming costly, or automatic metrics evaluating full images, unable attribute specific parts the images. In this work, we introduce a new set metrics, Decomposed Indicators Disparities Image Generation...

Text toxicity detection systems exhibit significant biases, producing disproportionate rates of false positives on samples mentioning demographic groups. But what about in speech? To investigate the extent to which text-based biases are mitigated by speech-based systems, we produce a set high-quality group annotations for multilingual MuTox dataset, and then leverage these systematically compare speech- classifiers. Our findings indicate that access speech data during inference supports...
