Establishment of Reference Interval for CA72‐4 in Healthy Adults in Shenzhen, China

Journal of Clinical Laboratory Analysis, EarlyView.
We established a reference interval (RI) for serum CA72‐4 in healthy adults in Shenzhen, China, based on data from 2614 individuals. Using CLSI EP28‐A3c guidelines, we determined an upper reference limit of 8.5 U/mL, which significantly reduced false‐positive results compared to the manufacturer's cutoff.

Steroidopathies and hormonal imbalance in children and adolescents with autism spectrum disorder

JCPP Advances, EarlyView.
Abstract Background Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition with a multifactorial etiology, many aspects of which remain unclear. Emerging evidence suggests a potential association between ASD and clinical manifestations resulting from hormonal imbalances, henceforth named “steroidopathies.” The present study aims to ...

Metabolic and hormonal serum markers in early childhood: Follow‐up of a randomized controlled trial during infancy evaluating a modified, low‐protein infant formula

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives High protein intake during infancy has been linked to accelerated weight gain and increased obesity risk. This study aimed to examine the effects of a low‐protein formula during the first 6 months of life on blood metabolic and hormonal markers during early childhood. Methods Formula‐fed infants (<45 days) were randomized to receive

Stirring Without Stirrers: Polymer Fouling‐Driven Mass Transport Unlocks Order‐of‐Magnitude Gain in Electrochemiluminescence

Advanced Science
Electrode reactions are central to analytical chemistry and a green approach to chemical synthesis. Here, it is demonstrated that sacrificing electrode‐electrolyte contact to microscale polymeric blocks creates fouled electrodes that outperform ...

Construction of a Non‐Invasive Predictive Model Based on PIVKA‐II Combined With MRI Imaging Features for Evaluating Microvascular Invasion in Hepatocellular Carcinoma

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study developed a non‐invasive model using PIVKA‐II and MRI features to predict microvascular invasion in hepatocellular carcinoma, providing a reliable tool for early risk assessment and personalized treatment planning. The study included 98 patients with pathologically confirmed HCC (Child‐Pugh A, BCLC stage A), comprising 43 MVI ...
