Bidirectional modification effects of non-optimal temperature and short-term exposure to fine particulate matter on cardiovascular diseases and their different subtypes: A time-case cross-design in multiple cities

This multi-city time-case crossover study in Anhui Province reveals that short-term PM2.5 exposure and low temperatures exert significant bidirectional synergistic effects on cardiovascular mortality, particularly for acute subtypes and among the elderly, whereas high temperatures only experience unidirectional amplification by PM2.5.

Rectal Colonization with Carbapenem-Resistant Enterobacterales in Intensive Care Unit Patients: Prevalence, Clinical Outcomes, and Risk of Subsequent Infection

This retrospective study of 3,221 ICU patients reveals that rectal colonization with carbapenem-resistant Enterobacterales is prevalent (8.9%), frequently leads to subsequent infection (51.6%), and is significantly associated with increased mortality, underscoring the critical need for early detection and rigorous infection control measures.

Five-Year Outcomes of UKA Versus TKA in Elderly Patients With Severe Varus Deformity in Knee Osteoarthritis: The Modifying Effect of Preoperative Extensor Muscle Radiomics Quality

In elderly patients with severe varus knee osteoarthritis, unicompartmental knee arthroplasty (UKA) demonstrates comparable five-year clinical outcomes to total knee arthroplasty (TKA) with reduced surgical trauma and faster early recovery, although the early functional advantage of UKA is attenuated in patients with poorer preoperative extensor muscle quality as quantified by radiomics.

Radiographic phenotypes of spinal deformity in osteogenesis imperfecta: a latent class analysis

This study utilized latent class analysis on radiographic data from 62 patients with osteogenesis imperfecta to identify two distinct spinal deformity phenotypes (severe and moderate), suggesting that this probabilistic classification approach could enhance prognostic assessment and guide individualized treatment strategies.

Application of Multifeature EEG Analysis and Machine Learning in the Investigation of Neurobiological Mechanisms of Schizophrenia

This study proposes a Genetic Algorithm-based Voting ensemble learning model (GA-Voting) that integrates power spectral density, fuzzy entropy, and phase lag index features from resting-state EEG data to achieve highly accurate (99.55%) diagnosis of schizophrenia while offering new insights into its underlying neurobiological mechanisms.

Scaling Village Health Leader–Led Community Maternal and Newborn Health Interventions in Underserved Ethiopian Communities: Evidence on Effectiveness, Safety, and Implementation

This study demonstrates that scaling up Village Health Leader–led community interventions in underserved Ethiopian agrarian and pastoralist settings is a feasible, safe, and effective strategy that significantly improves maternal and newborn health outcomes, including increased facility deliveries, reduced postpartum hemorrhage, and higher uptake of essential commodities like misoprostol and family planning.

Adipose-derived mesenchymal stem cell-derived exosomal miR-22-3p alleviates depression-like behaviors via the FURIN/HMGB1 axis

This study demonstrates that intranasal administration of adipose-derived mesenchymal stem cell-derived exosomes engineered to deliver miR-22-3p alleviates depression-like behaviors in a rat model by inhibiting the FURIN/HMGB1 axis, thereby reducing neuroinflammation and neuronal apoptosis.
