What if your most powerful health signal isn’t a lab test or scan—but a single night of sleep?
This issue looks at how AI is turning sleep and other “quiet” signals into early‑warning systems, from SleepFM predicting long‑term disease risk to home devices capturing clinical‑grade data.
Across these stories, AI doesn’t replace clinicians; it surfaces risk long before symptoms force a visit.

Summaries are for education, not medical advice. Always verify locally before clinical use.

Researchers introduced SleepFM, a sleep foundation model trained on over 585,000 hours of polysomnography from 65,000+ individuals. Utilizing EEG, ECG, EMG, and respiratory signals, the model learned sleep patterns and predicted future risks for 130 conditions, including mortality, dementia, heart attack, and stroke, from a single night's data.

Why it matters

  • Uses large-scale, real-world PSG data to predict disease risk from sleep signals

  • Works across different PSG setups (more generalizable than many sleep models)

  • Shows how foundation models can make sleep data scalable for screening and prevention

A JAMA Cardiology analysis of the SPRINT trial found that adults with hypertension and prediabetes face a higher heart failure risk when subclinical myocardial injury or stress is present, indicated by elevated hs-troponin I or NT-proBNP.

Why it matters

  • Identifies a high-risk phenotype before clinical HF develops

  • Shows glycemic dysregulation and cardiac biomarkers act synergistically

  • Supports integrating glucose status with biomarker profiling for prevention

How much could AI save your support team?

Peak season is here. Most retail and ecommerce teams face the same problem: volume spikes, but headcount doesn't.

Instead of hiring temporary staff or burning out your team, there’s a smarter move. Let AI handle the predictable stuff, like answering FAQs, routing tickets, and processing returns, so your people focus on what they do best: building loyalty.

Gladly’s ROI calculator shows exactly what this looks like for your business: how many tickets AI could resolve, how much that costs, and what that means for your bottom line. Real numbers. Your data.

A Scientific Reports study trained deep learning models on 79,246 lesion images and 22 clinical/meta features. Image-only models showed high sensitivity but many false positives. Including metadata improved specificity for benign lesions, and an ensemble approach increased accuracy, enhancing teledermatology triage speed, accuracy, and clinician explainability.

Why it matters

  • Fewer false positives → fewer unnecessary urgent visits/biopsies, shorter waitlists

  • Risk stratification becomes multimodal: phenotype + patient context beats images alone

  • Explainability layer makes deployment more clinically defensible (where the model “looked”)

🩺CES 2026 spotlight: Withings Body Scan 2

Withings delivered a standout health-tech moment at CES 2026 with Body Scan 2, a $599.95 home “longevity station” designed to bring deeper health signals into the home. The emphasis wasn’t replacing clinicians, but capturing earlier, continuous insight with less friction.

👁️ A common eye ointment may quietly damage glaucoma implants

Researchers at Nagoya University discovered that petrolatum-based eye ointments can cause glaucoma implants to swell, weaken, and rupture by absorbing into the implant material. Damage occurs only with direct contact, raising concerns about post-surgery eye care.

Why it matters

  • Reveals an overlooked risk in standard post-glaucoma surgery care

  • Highlights the importance of matching medications with implant materials

  • May prompt changes in clinical guidelines to prevent avoidable implant failure
