Sự viêm vi mạch bẩm sinh sớm và kích hoạt nội mô xác định đặc điểm miễn dịch chủng khác sau ghép tim lợn sang người

Sự viêm vi mạch bẩm sinh sớm và kích hoạt nội mô xác định đặc điểm miễn dịch chủng khác sau ghép tim lợn sang người

Phân tích đa chế độ của hai quả tim lợn đã được chỉnh sửa gen 10 gen được ghép vào người đã chết não cho thấy sự viêm vi mạch bẩm sinh sớm với kích hoạt nội mô và hồ sơ phân tử phù hợp với tổn thương do kháng thể mặc dù không có C4d trong mao mạch. Một cách tiếp cận chẩn đoán chính xác có thể cải thiện giám sát ghép.
Early Innate Microvascular Inflammation and Endothelial Activation Define the Xenoimmune Signature After Pig-to-Human Heart Transplantation

Early Innate Microvascular Inflammation and Endothelial Activation Define the Xenoimmune Signature After Pig-to-Human Heart Transplantation

Multimodal analysis of two 10-gene–edited pig hearts transplanted into brain-dead human recipients revealed early innate microvascular inflammation with endothelial activation and a molecular profile consistent with antibody-mediated injury despite absent capillary C4d. A precision diagnostic approach may improve graft surveillance.
Elevated Blood Pressure in Adolescence Predicts Dose‑Dependent Coronary Atherosclerosis in Middle Age: Implications for Early Detection and Prevention

Elevated Blood Pressure in Adolescence Predicts Dose‑Dependent Coronary Atherosclerosis in Middle Age: Implications for Early Detection and Prevention

A Swedish cohort study of 10,222 men linked adolescent blood pressure to coronary atherosclerosis by CCTA ~40 years later; higher systolic BP in adolescence, even in the ‘elevated’ range, was associated with greater odds of severe (>50%) coronary stenosis in middle age.
Underweight in Type 2 Diabetes Raises Cardiovascular Risk — Severe Leanness Carries Greater Risk Than Obesity

Underweight in Type 2 Diabetes Raises Cardiovascular Risk — Severe Leanness Carries Greater Risk Than Obesity

A nationwide Korean cohort found that underweight patients with Type 2 diabetes—especially those with severe underweight—have higher cardiovascular risk than normal-weight and even some obese patients, underscoring the need to screen and manage malnutrition, sarcopenia, and frailty in diabetes care.
Excessive Glycosylation and the HBP–ISR Axis: A Metabolic Driver of Thoracic Aortic Aneurysm with Therapeutic Implications

Excessive Glycosylation and the HBP–ISR Axis: A Metabolic Driver of Thoracic Aortic Aneurysm with Therapeutic Implications

A preclinical and human tissue study shows up-regulation of the hexosamine biosynthetic pathway and downstream integrated stress response in thoracic aortic aneurysm, linking excessive glycosylation to vascular smooth muscle cell dysfunction and medial degeneration; pharmacologic inhibition reverses disease features in a Marfan model.
METTL14 and LATS1/2 Define Divergent Endothelial Programs That Drive Vascular Ageing and Atherothrombosis — New Therapeutic Nodes in Cardio‑Vascular Senescence

METTL14 and LATS1/2 Define Divergent Endothelial Programs That Drive Vascular Ageing and Atherothrombosis — New Therapeutic Nodes in Cardio‑Vascular Senescence

Two complementary studies identify METTL14/TLR4 and LATS1/2–CD38–SUOX axes as key drivers of endothelial senescence phenotypes that promote arterial ageing, stiffness, fragile neovessels and atherothrombotic plaque formation, highlighting new biomarker and therapeutic opportunities.
Real-time Sepsis Risk Prediction in Acute Gastrointestinal Bleeding: A Validated Dynamic Monitoring Tool That Improves Early Stratification

Real-time Sepsis Risk Prediction in Acute Gastrointestinal Bleeding: A Validated Dynamic Monitoring Tool That Improves Early Stratification

A multicenter Chinese study developed and validated a real-time nomogram that predicts sepsis in acute gastrointestinal bleeding (AGIB) using clinical and laboratory variables; the tool showed strong discrimination (AUCs 0.827–0.884), good calibration, and an online monitoring platform for dynamic alerts.
Preoperative Pembrolizumab Plus Chemoradiotherapy (PPCT) for Locally Advanced Resectable ESCC: PALACE‑2 Phase 1/2 Results and Immune‑Microenvironment Insights

Preoperative Pembrolizumab Plus Chemoradiotherapy (PPCT) for Locally Advanced Resectable ESCC: PALACE‑2 Phase 1/2 Results and Immune‑Microenvironment Insights

PALACE‑2 reports that preoperative pembrolizumab combined with chemoradiotherapy produced a 43.2% pathologic complete response in resectable, locally advanced esophageal squamous cell carcinoma, with acceptable short‑term survival and a high rate of grade ≥3 toxicities; IL‑6 emerged as a potential predictive and targetable mediator of response.
Early IL‑17A Blockade vs Step‑Up Therapy in Psoriatic Arthritis: STAMP trial shows no superior 6‑month benefit for secukinumab-first treat‑to‑target strategy

Early IL‑17A Blockade vs Step‑Up Therapy in Psoriatic Arthritis: STAMP trial shows no superior 6‑month benefit for secukinumab-first treat‑to‑target strategy

The STAMP randomized trial found that a treat‑to‑target strategy starting with secukinumab plus methotrexate did not achieve superior 6‑month ACR50 rates versus a conventional methotrexate‑first step‑up approach; 12‑month outcomes were similar for both strategies.
Extratemporal epilepsy, obesity and male sex predict SUDEP risk in drug‑resistant focal epilepsy: clinical insights from the REPO2MSE prospective case‑control study

Extratemporal epilepsy, obesity and male sex predict SUDEP risk in drug‑resistant focal epilepsy: clinical insights from the REPO2MSE prospective case‑control study

A multicentre prospective nested case‑control analysis (REPO2MSE) identifies extratemporal seizure onset, BMI ≥30, male sex, and predominantly nocturnal seizures as independent SUDEP risk factors in drug‑resistant focal epilepsy; peri‑ictal hypoxaemia and focal‑to‑bilateral tonic‑clonic seizure frequency were not significant.
