Multiple maternal chronic conditions and risk of severe neonatal morbidity and mortality

JAMA Network Open

2026-01-23

(Press-News.org) About The Study: In this study, risks of severe neonatal morbidity or mortality increased with an increasing number of preexisting maternal chronic conditions. These findings suggest that women and adolescents with multiple chronic conditions may benefit from preconception counseling to optimize chronic disease management, monitoring in pregnancy for earlier identification of complications, and enhanced newborn supports.

Ion accumulation in liquid–liquid phase separation regulates biomolecule localization

2026-01-23

Liquid–liquid phase separation is a process in which a uniform solution separates into two coexisting liquid phases. In living cells, it governs the formation of membrane-less compartments that selectively concentrate molecules and regulate biochemical reactions. This phenomenon is also widely used in practical applications, including biomolecular separation and purification. A long-standing question in phase separation research is why specific molecules preferentially localize in one phase over the other. Conventional explanations have focused on polymer–polymer ...

Hemispheric asymmetry in the genetic overlap between schizophrenia and white matter microstructure

2026-01-23

Schizophrenia is a highly heterogeneous psychiatric disorder affecting ~1% of the global population, typically emerging in adolescence or early adulthood and characterized by hallucinations, delusions, disorganized thinking, and cognitive impairments; while its etiology remains elusive, genetic factors are widely recognized as fundamental, and GWAS have identified over 200 genome-wide significant loci. White matter microstructure is essential for neural communication and is strongly heritable; diffusion tensor imaging (DTI) quantifies white matter integrity via FA, MD, and the three tensor eigenvalues (λ1–λ3), and widespread ...

Nano-immunotherapy synergizing ferroptosis and STING activation in metastatic bladder cancer

2026-01-23

Metastatic urothelial carcinoma has a poor prognosis: ~50% of muscle-invasive bladder cancer progresses to metastasis, and the 5-year survival for advanced/metastatic disease is <10%. Platinum-based chemotherapy was historically first-line, but its benefit is limited by renal insufficiency/poor tolerance and the lack of effective options after resistance. Immune checkpoint inhibitors have improved outcomes in a subset of patients and are supported by high tumor mutational burden and PD-L1 expression in bladder cancer; however, response ...

Insilico Medicine receives IND approval from FDA for ISM8969, an AI-empowered potential best-in-class NLRP3 inhibitor

2026-01-23

Investigational New Drug (IND) approval from the U.S. Food and Drug Administration (FDA) paves the way for ISM8969 clinical study in the United States. The Phase I clinical trial aims to evaluate safety, tolerability, and pharmacokinetics profiles. ISM8969 is a novel oral therapeutic candidate developed through Insilico’s Pharma.AI, with best-in-class potential, unique brain penetrant traits, and favorable druggability profiles demonstrated in preclinical studies. Insilico Medicine has entered into a co-development collaboration agreement with Hygtia Therapeutics, with both parties each holding 50% of ...

Combined aerobic-resistance exercise: Dual efficacy and efficiency for hepatic steatosis

2026-01-23

Hepatic steatosis is a core pathological feature of metabolic dysfunction-associated steatotic liver disease (MASLD). It not only drives disease progression to intrahepatic conditions such as cirrhosis but also elevates the incidence and mortality risk of cardiovascular diseases and extrahepatic malignancies. Importantly, hepatic steatosis is reversible in its early stages. Clinical practice guidelines recommend exercise intervention as the primary approach for treating the disease, and the concept of "exercise as medicine" is widely acknowledged. In recent years, researchers have mainly evaluated how different components of exercise prescriptions affect health ...

Expert consensus outlines a standardized framework to evaluate clinical large language models

2026-01-23

A new expert consensus made available online on 10 October 2025 and published in Volume 5, Issue 4 of the journal Intelligent Medicine on 1 November 2025, sets out a structured framework to assess large language models (LLMs) before they are introduced into clinical workflows. The guidance responds to the rapid uptake of artificial intelligence (AI) tools for diagnostic support, medical documentation, and patient communication, and the corresponding need for consistent evaluation of safety, effectiveness, and fairness. The consensus formalizes retrospective evaluation—testing ...

Bioengineered tissue as a revolutionary treatment for secondary lymphedema

2026-01-23

The rising incidence of cancer worldwide has led to an increasing number of surgeries that involve the removal of lymph nodes. Although these procedures play a major role in cancer staging and preventing the spread of malignancies, they sometimes come with severe long-term consequences. Since lymph nodes do not naturally regenerate once removed, their absence can lead to a condition known as secondary lymphedema. It manifests as chronic swelling, discomfort, and reduced mobility in affected limbs or regions, severely affecting a patient’s quality of life. Consequently, a major focus within the ...

Forty years of tracking trees reveals how global change is impacting Amazon and Andean Forest diversity

2026-01-23

New research published in Nature Ecology and Evolution reveals significant recent shifts in tree diversity among the tropical forests of the Andes and Amazon, driven by global change. The study, led by Dr Belen Fadrique from the University of Liverpool, uses 40 years of records on tree species collected by hundreds of international botanists and ecologists in long-term plots to offer comprehensive insights into tree diversity change in the world’s most diverse forests. Key Findings At the continental level, ...
