IL-10 Autoantibodies May Drive Inflammatory Bowel Disease in a Subset of Patients

A 2026 NEJM study analyzing data from more than 4,900 people with inflammatory bowel disease found that about 3.5% carry autoantibodies that block interleukin-10, effectively removing an anti-inflammatory brake and potentially driving disease in this subset; the autoantibibody presence is linked to the HLA-DRB1*01:03 variant, suggesting possibilities for early genetic testing and more targeted, mechanism-based therapies.

Personalized digital twins forecast lung fate during ex vivo perfusion

Personalized digital twins forecast lung fate during ex vivo perfusion

Researchers analyzed data from nearly 1,000 EVLP procedures to train a hybrid physics-ML model that creates a dynamic digital twin of a lung, enabling time-resolved predictions of 75+ functional and molecular parameters and early updates as new data arrive. The twin serves as a personalized control to predict no-treatment trajectories, allowing comparison with actual therapy (e.g., alteplase) to assess responses while reducing reliance on matched organs and mitigating inter-organ variability in preclinical transplantation studies.

Gene test could spare many breast cancer patients from chemotherapy

An international trial found the Prosigna gene test can identify early breast cancer patients who can forgo chemotherapy, sparing about two-thirds of participants to receive hormone therapy alone; five-year survival was 93.7% without chemo versus 94.9% with chemo, suggesting broader adoption could save NHS patients thousands of chemotherapy sessions annually, though results for under-40s remain uncertain.

Genomic test could spare millions of breast cancer patients from chemotherapy

The Optima trial, involving over 4,000 women with hormone-positive breast cancer, used the Prosigna genomic test to guide treatment. Women with low genomic risk received hormone therapy alone, while high-risk patients still received chemotherapy; at five years, survival and cancer-free rates were nearly identical (95% vs 94%), suggesting many could safely skip chemotherapy and reduce toxicity, heralding more personalized care.

AI-Guided Mood Plan Yields 55% Depression Remission in Trial

UC San Diego researchers used two weeks of smartwatch data and EMA mood logs to train a personalized machine‑learning model that identifies each participant’s top mood drivers and pairs them with tailored, remote coaching to create an individualized Mood Augmentation Plan (iMAP). Over six weeks, 55% of participants showed depression remission on PHQ-9, anxiety decreased 36%, and benefits persisted for three months post-intervention, suggesting a scalable, data‑driven approach to personalized depression care.

The Pace of Poop Could Shape Your Health, New Analysis Finds

A 2023 review of data from thousands of participants links how long stool spends in the gut to distinct microbiome profiles and health outcomes. Faster transit tends to favor carbohydrate-digesting bacteria, slower transit favors protein-utilizing microbes, and both extremes show reduced microbial diversity. Incorporating transit time improves predictions of gut microbiota beyond diet alone and could influence responses to probiotics and treatments, highlighting potential for personalized diet and therapy based on an individual’s gut rhythm.

Smartwatch data plus routine labs power scalable insulin-resistance screening

Smartwatch data plus routine labs power scalable insulin-resistance screening

The WEAR-ME study (n=1,165) shows that combining wearable time-series data with demographics and routine blood biomarkers can predict insulin resistance (HOMA-IR ≥2.9) with AUROC around 0.80. Using a wearable foundation model to derive richer representations further improves performance, achieving AUROC ~0.82 in cross-validation, and up to ~0.88 when fasting glucose and a lipid/metabolic panel are included. An independent validation cohort confirms gains with wearable data, and an LLM-based insulin-resistance literacy agent is demonstrated to contextualize results and provide personalized guidance. The work proposes a scalable, noninvasive screening approach to identify at-risk individuals for early lifestyle interventions to prevent type 2 diabetes, while noting limitations in data missingness, generalizability, and the need for longitudinal validation.

Your body’s digital twin could guide highly personalized surgery

Live Science interviews Dr. John Pandolfino about a 400‑person clinical trial using a mechanically accurate digital twin of the esophagus to predict the best myotomy approach for achalasia and reduce complications like diverticulum. The virtual model guides surgical decisions, could lessen or replace some animal testing, and may eventually be extended to other organs such as the heart and bladder, though a fully comprehensive, molecular‑level digital twin remains a longer‑term goal.

UCSD launches survival epidemiology to study life after diagnosis

A UC San Diego professor introduces 'survival epidemiology,' a field focused on identifying factors that help people live longer after a disease diagnosis rather than just preventing disease, using large electronic health records to tailor treatments and improve outcomes. The approach ties to Cuomo's broader work, including the Nutritional Epidemiology Risk-Survival Paradox, which suggests some factors linked to higher disease risk may enhance survival after diagnosis.

First-Ever Personalized CRISPR Therapy Helps Infant With CPS1 Deficiency Thrive

Researchers at Children’s Hospital of Philadelphia and the University of Pennsylvania developed a bespoke base-editing CRISPR therapy delivered to the liver to fix a CPS1 gene variant in a newborn with a rare metabolic disorder. After a first infusion in early 2025 and subsequent doses, the child has tolerated treatment with no adverse effects, has been able to halt medications and gradually reintroduce protein, and is thriving per a New England Journal of Medicine report; the approach is experimental and not FDA-approved, but signals a path toward patient-specific gene therapies that could be scalable to individual needs.
