AI software-as-a-medical-device platforms cleared since 2019 that estimate sleep parameters improve accessibility to obstructive sleep apnea diagnosis for patients unable or unwilling to undergo in-laboratory polysomnography.

By August 2026, peer-reviewed guidance for neurologists described a shift in obstructive sleep apnea diagnosis from in-laboratory polysomnography alone to home testing augmented by wearables, nearables, and FDA-cleared software-as-a-medical-device platforms that leverage artificial intelligence and multisignal integration to estimate sleep parameters. The article framed these tools as improving accessibility for patients unable or unwilling to undergo lab studies.

A random forest model trained on 16S rRNA microbial community data from a field mesocosm predicted antifouling paint particle presence in sediment, with perfect detection of presence in test set and correct classification of all uncontaminated and 3 of 5 contaminated real-world Baltic Sea sites.

On 2026-08-03, a peer-reviewed study reported a random forest model trained on 16S rRNA gene sequencing from a field mesocosm to predict antifouling paint particle contamination in sediment. In lab incubation tests it identified 100% of presence samples and 83.3% of absence samples, and when applied to 14 Baltic Sea and Warnow estuary sites it correctly labeled all uncontaminated sites and three of five contaminated sites.

Logistic regression achieved comparable discrimination to 14 machine learning algorithms for 28-day mortality prediction in young adults with acute poisoning and enabled a clinically usable nomogram for early risk stratification.

A multicenter study of 556 young adults with acute poisoning compared 14 machine learning algorithms to traditional logistic regression for predicting 28-day mortality. Using six LASSO-selected factors including herbicide poisoning, white blood cell count and shock, logistic regression matched the best machine learning model on discrimination and calibration, leading authors to build a nomogram for early risk stratification.

Caregivers reported nuanced tensions and concerns about using the chatbot for mental health support, including gaps around crisis management, personalization, and data privacy.

On March 24, 2026, researchers reported developing Carey, a GPT-4o-based chatbot intended to provide informational and emotional support to family caregivers of people with Alzheimer's and related dementias. They used Carey as a technology probe in semi-structured interviews with 16 caregivers after scenario-driven interactions, identifying six themes of need and expectation.

Deploying foundation models in healthcare is limited by longstanding difficulties obtaining and processing high-quality clinical data due to quantity, annotation, privacy, and ethics constraints.

Published March 28, 2026 in ACM Computing Surveys, this survey examines data-centric foundation models in computational healthcare, covering approaches from pre-training to inference aimed at improving clinical workflows. It highlights the shift toward data characterization, quality, and scale, and provides a public list of models and datasets.

AI systems pose risks across seven effect areas ranging from discrimination and privacy violations to misinformation and weapons development that concern auditors, policymakers, companies and the public.

On March 30 2026, a peer-reviewed paper in Patterns described the AI Risk Repository, a living database of 1,725 risks extracted from 74 existing taxonomies and frameworks. The authors created two complementary systems to organize them: a Causal Taxonomy by origin, intent and timing, and a Domain Taxonomy by effects across seven areas.
