Circulating MOTS-c levels are decreased in obese male children and adolescents and associated with insulin resistance
Du C, Zhang C, Wu W, +7 · Pediatric Diabetes
Circulating MOTS-c was significantly lower in obese male Chinese children and adolescents than in normal-weight controls and correlated inversely with HOMA-IR — the first paediatric demonstration of the mitochondrial-derived-peptide-and-insulin-resistance association predicted by Lee 2015.

Efficacy of DSIP to normalize sleep in middle-aged and elderly chronic insomniacs
Schneider-Helmert D · European Neurology
18 chronic-insomnia patients across two age strata; middle-aged subjects (29–59) reached normal sleep values by end of one week of DSIP dosing, while elderly subjects (60–83) required the post-treatment follow-up week to achieve the same normalisation — an age-dependent response curve unique in the DSIP literature.

The Association Between Serum MOTS-c Levels and Myocardial Ischemia-Reperfusion Injury in Patients with Acute Myocardial Infarction: A Cross-Sectional Study
Peng L, Li Y, Duan X, +3 · Biomedicines
In 72 acute myocardial infarction patients undergoing PCI, postoperative peripheral serum MOTS-c levels were significantly lower in the 34 patients who developed myocardial ischemia-reperfusion injury versus the 38 who did not, with an adjusted odds ratio of 0.986 (95% CI 0.976-0.996) — the first human clinical-cohort biomarker data linking endogenous MOTS-c to acute cardiac injury.

Semaglutide is associated with stiffness improvement and broad liver benefits with distinct dose- and weight-linked patterns
Soundararajan V, Venkatakrishnan AJ, Murugadoss K, +3 · medRxiv (preprint)
In a de-identified federated EHR network of 489,785 semaglutide-treated adults plus a paired elastography substudy of 326 patients, median liver stiffness fell from 4.85 to 3.9 kPa (−0.38 kPa, p<0.001); 40.8% achieved ≥20% reduction and 80% of those with cirrhosis-range baseline (≥12.5 kPa) hit that threshold — with stiffness improvement appearing in patients with no weight loss as often as in those with ≥10% weight loss, and hepatic GLP1R expression at only 0.0239% suggesting a largely non-direct mechanism.

Legacy neuropsychiatric benefit after semaglutide is linked to maximum achieved dose and independent of the maximum weight lost
Murugadoss K, Venkatakrishnan A, Soundararajan V · medRxiv (preprint)
From 489,785 semaglutide-treated adults in a federated EHR network, 63,215 patients with baseline neuropsychiatric conditions showed broadly lower 2-year neuropsychiatric event risk versus propensity-matched metformin, SGLT2i and DPP-4i users; higher attained pre-landmark dose was independently associated with lower post-landmark incidence of substance-related, mood, anxiety, CNS-atrophy, neuromuscular, eating/sleep/behavioral and personality/impulse-control disorders — effects that were weight-loss-independent for most outcomes, with confirmed CNS GLP1R expression in hypothalamus, caudate, putamen, NAcc and cerebellum supporting a direct CNS engagement model.
