Association Between Heavy Metal Exposure and Autism Spectrum Disorders: Discrepancies, Research Gaps, and Future Priorities of Human Epidemiological Studies

GeoHealth, Volume 10, Issue 8, August 2026.
Abstract Autism spectrum disorder (ASD) in children is a major public health challenge. The potential epidemiological links between heavy metal exposure and ASD remains a controversial issue. This critical review examines the epidemiological discrepancies, including variations in exposure assessment, study design, and population differences that ...

Correlation between urinary contents of some metals and fasting plasma glucose levels: A cross-sectional study in China

Ecotoxicology and Environmental Safety, 2021
Many metals are involved in the pathogenesis of diabetes, but most of existing studies focused on single metals. The study of mixtures represents real-life exposure scenarios and deserves attention.

A Low Serum Calcium‐to‐Potassium Ratio Predicts Postpartum Venous Thromboembolism Risk: Mediation by Hemoglobin and D‐Dimer in a Multicenter Cohort

MedComm, Volume 7, Issue 7, July 2026.
In a large multicenter cohort, a low serum calcium‐to‐potassium (Ca/K) ratio (< 0.55) in the third trimester was a novel risk factor for postpartum venous thromboembolism (VTE). This association was partly explained by concomitant variations in hemoglobin and D‐dimer levels, pointing to integrated management of electrolytes and anemia for postpartum ...

Bayesian Wavelet and Fourier Transform Kernel Regression and Classification in RKHS [PDF]

, 2021
Kernel methods are often used for nonlinear regression and classification in machine learning because they are computationally cheap and accurate. Fourier basis and wavelet basis are the bases that can efficiently approximate the kernel functions.

Association Between Volatile Organic Compound Metabolites in Urine and Adult Lung Function: Evidence From NHANES 2011–2012

The Clinical Respiratory Journal, Volume 20, Issue 5, May 2026.
Using BKMR, we observed the joint effects of 16 UM‐VOCs on adult lung function decline. Urinary AMCC and CYMA were identified as the most important contributors to the decline in FEV1/FVC and FeNO, respectively. Tobacco smoke may be the main source of VOCs exposure.

Redefining the Health Risk of Battery Materials Through a Biologically Transformed Metal Mixture

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Inhaled NCM particles undergo lysosomal degradation, releasing complex ion mixtures that induce systemic impact. The impact is determined by a critical balance between antagonistic Ni‐Co interactions and synergistic Mn effects. To capture these complexities in risk assessment, we develop an IAI model, ensuring a more accurate quantitative risk ...

Composite dietary antioxidant index and HPV infection from single and mixed associations to SHAP-interpreted machine learning predictions

Frontiers in Nutrition
BackgroundSome studies have shown that dietary antioxidants may prevent the occurrence of Human Papillomavirus (HPV) infection. However, the relationship between the composite dietary antioxidant index (CDAI) and HPV infection among adult women in the ...
