Background: Cardiac troponin I (cTnI) is a well-established marker for detecting myocardial ischemic damage in neonates with hypoxic-ischemic encephalopathy. However, the predictive value of cTnI in assessing mortality in neonatal asphyxia remains obscure. This retrospective study aims to analyze the relationship between cTnI levels in blood serum with gestational age, birth weight, gender, delivery type, electrocardiography, echocardiography, Apgar scores, length of hospital stay, and mortality in asphyxiated neonates.
Methods: This study included 164 full-term neonates with evidence of asphyxia. Myocardial markers, electrocardiography, and echocardiography were assessed in the first 24 hours after birth in neonates with asphyxia. The length of hospital stay and short-term outcome were assessed.
Results: There were no statistically significant correlations found between cTnI concentrations and traditional markers of asphyxia, length of hospitalization or mode of delivery. However, high cTnI levels were significant predictors of mortality in neonates with birth asphyxia.
Conclusions: This study highlights the significance of monitoring cardiac injury in asphyxiated neonates. Serum cTnI levels measured at 24 hours after birth are likely to have significant predictive value for assessing mortality in neonates with birth asphyxia.

Efficacy and safety of creatine phosphate sodium in the treatment of viral myocarditis: A systematic review and meta-analysis.
PLoS One

Department of Pediatrics, Quanzhou First Hospital, Quanzhou, Fujian Province, China.
Purpose: To systematically evaluate the efficacy and safety of creatine phosphate sodium in the treatment of viral myocarditis, and to provide guidance for its clinical treatment.
Methods: We conducted a search of The Cochrane Library, PubMed, EMbase, and Web of Science databases to retrieve randomized controlled trials (RCTs) on the use of creatine phosphate sodium (CPS) in the treatment of viral myocarditis. The search was conducted up to April 2024.
Effects of vitamin D supplementation on cardiac biomarkers: Results from the STURDY trial.

Objectives: In observational studies, older adults with low serum vitamin D levels are at higher risk of cardiovascular disease (CVD), but randomized trials have failed to demonstrate reduction in CVD risk from vitamin D supplementation, possibly because the doses of vitamin D supplements tested were too low. Our objective was to determine if higher doses of vitamin D supplementation reduce high-sensitivity cardiac troponin (hs-cTnI) and N-terminal pro-b-type natriuretic peptide (NT-proBNP), markers of subclinical CVD.
Methods: The Study to Understand Fall Reduction and Vitamin D in You (STURDY) was a double-blind, randomized, response-adaptive trial that tested the effects of 4 doses of vitamin D3 supplementation (200, 1000, 2000, 4000 IU/day) on fall risk among older adults with low serum 25-hydroxyvitamin D concentrations (10-29 ng/mL).
Intra-Mesopore Immunoassay Based on Core-Shell Structured Magnetic Hierarchically Porous ZIFs.

It is crucial yet challenging to sensitively quantify low-abundance biomarkers in blood for early screening and diagnosis of various diseases. Herein, an analytical model of intra-mesopore immunoassay (IMIA) was proposed, which was competent to examine various biomarkers at the femtomolar level. The success is rooted in the design of an innovative superparamagnetic core-shell structure with FeO nanoparticles (NPs) at the core and hierarchically porous zeolitic imidazolate frameworks as a shell (FeO@HPZIF-8), achieved through a soft-template directed self-assembly coupled with confinement growth mechanism.

Background: Cardiac myosin binding protein C (cMyC) is an emerging new biomarker of myocardial injury rising earlier and cleared faster than cardiac troponins. It has discriminatory power similar to high-sensitive troponins in diagnosing myocardial infarction in patients presenting with chest pain. It is also associated with outcome in patients with acute heart failure.

Background: ST-segment elevation myocardial infarction (STEMI) is a common and severe form of acute myocardial infarction (AMI).
Objectives: The study aimed to investigate the relationship between serum nitric oxide (NO) and endothelin-1 (ET-1) levels with the severity of STEMI and their predictive value for major adverse cardiovascular events (MACE) within one year after percutaneous coronary intervention (PCI) in STEMI patients.
Methods: The retrospective study was conducted on 269 STEMI patients who underwent PCI.
