Real-world, digital-first delivery of GLP-1 receptor agonist therapy in women.

October 16, 2026| Source: Nature medicine

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have demonstrated substantial weight reduction and cardiometabolic benefit in randomized trials; however, prospective implementation evidence from digital care models and female sex community populations remains limited. Here we report outcomes from an observational study of 8,127 women initiating GLP-1RA therapy (99.8% tirzepatide) through a structured digital program incorporating mandatory biochemical monitoring, weekly video-supported follow-up and clinician-guided dose titration in the UK. Mean weight reduction was 16.1 kg (95% confidence interval 15.9 to 16.2; P < 0.001), representing 15.5% of baseline weight; 83.1% achieved ≥10% and 22.4% achieved ≥20% weight loss, with consistent responses across age, baseline weight and socioeconomic strata. Among participants with paired biomarker data, mean glycated hemoglobin decreased by 3.3 mmol mol - 1 (95% confidence interval 3.1 to 3.4; P < 0.001), normalizing in 84.5% of those with baseline diabetes-range values and 96.3% with prediabetes, and lipid parameters improved significantly (reductions in total cholesterol of 0.77 mmol l - 1 , low-density lipoprotein cholesterol of 0.61 mmol l - 1 and triglycerides of 0.47 mmol l - 1 ). Retention was 91.4% at 6 months, with no serious treatment-related adverse events. These findings support the feasibility of delivering structured, digitally enabled obesity pharmacotherapy at scale and provide prospective real-world implementation evidence for this care model. Interpretation is limited by the observational design, absence of a comparator group, self-pay population and 6-month follow-up.

The honey bee stinger: An unusual pump with collapsible double pistons.

Most stinging animals deliver venom by contracting muscles around a venom reservoir, but honey bees employ a fundamentally different strategy. The stingers of worker bees have the unique ability to autotomize, separating from the body, to continue to sting independently. Despite more than a century of anatomical descriptions, the mechanics of venom pumping have remained unresolved due to the challenges of observing them in action. We recorded high-speed videos of active, autotomized stingers, co

Chronic cigarette smoke exposure induces distinct stem cell states driving genetic driver-specific non-small cell lung cancer subtypes.

Cigarette smoke-induced chronic inflammation (CI) potentiates development of non-small cell lung cancer (NSCLC) by mediating genetic and epigenetic events. Using normal lung organoids (LOs), we define how chronic cigarette smoke condensate (CSC) exposure drives two separate stem cell populations to evolve premalignant states harboring progressive epigenetic and linked transcriptomic abnormalities in the absence of major driver mutations. These dynamics facilitate evolution of an immune evasive s

Cell identity competes with surface tension to determine stromal organization in tumor spheroids beyond the CAF shell paradigm.

Cancer-associated fibroblasts (CAFs) are often found forming a peripheral stromal barrier around tumors. Here, this paradigm is challenged using microfabricated 3D cancer-CAF spheroid models combined with quantitative magnetic force tensiometry. A surface tension atlas is established for eight cancer cell lines, three CAF populations, and heterotypic tumor-CAF assemblies, spanning nearly two orders of magnitude. Surface tension is first shown to govern spheroid morphology and modulate drug respo

Controlled functionalization of cellulose nanocrystals directs polymer-specific protein coronas and immune cell interactions.

Polymer coatings are widely used to suppress nonspecific protein adsorption and modulate nanoparticle-cell interactions. However, the biological outcomes of polymer-functionalized nanoparticles remain difficult to predict in complex biological environments because protein corona formation rapidly alters nanoparticle identity. This challenge is particularly pronounced when hydrophobic moieties are incorporated for imaging or therapeutic applications, as they can promote nonspecific interactions a

Dynamic partitioning shapes the in vivo organization of the Escherichia coli RNA degradosome.

The bacterial RNA degradosome is a central mediator of RNA turnover, yet how its components are organized and regulated in living cells remains unclear. Using live-cell single-molecule imaging, we quantified the spatial distribution and dynamics of the four major Escherichia coli degradosome components: RNase E, RhlB, PNPase, and enolase. These proteins occupied distinct membrane-associated and cytoplasmic pools whose relative abundance varied among proteins and changed with physiological state.
