Article Abstract
Chenxiang Huaqi Tablet (CXHQT) is a Chinese patent medicine preparation composed of 10 traditional Chinese herbs. In this study, the concentrations of 23 inorganic elements in CXHQT were determined by inductively coupled plasma mass spectrometry (ICP-MS). The fingerprint of the elements was established, the chemometrics and element correlation analysis were carried out, and the health risk assessment of heavy metals and harmful elements was performed. The results revealed that there were certain differences in the content of inorganic elements in 15 batches of CXHQT manufactured by the same pharmaceutical company. Pb, U, Al, Ga, Cd, As, Co, Ni, and Fe were identified as characteristic elements contributing to quality differences by chemometric analysis. In addition, the results of health risk assessment, such as total hazard index (HI) and total carcinogenic risk (TCR), indicated that the content of Al, Cr, Mn, Co, Ni, Cu, Zn, As, Sr, Cd, and Pb in CXHQT was within the normal range and would not endanger human health. This study provided a scientific and comprehensive reference for evaluation of inorganic elements and safety in CXHQT.

Risk of colorectal cancer and participation in fecal immunochemical test-based screening.
Public Health
September 2025
Department of Public Health, Erasmus MC University Medical Center, Rotterdam, the Netherlands.
Objectives: Participation rates in fecal immunochemical test (FIT)-based colorectal cancer (CRC) screening differ across socio-demographic subgroups. The largest health gains could be achieved in subgroups with low participation rates and high risk of CRC. We investigated the CRC risk within different socio-demographic subgroups with low participation in the Dutch CRC screening program.

Study Objective: Accurately predicting which Emergency Department (ED) patients are at high risk of leaving without being seen (LWBS) could enable targeted interventions aimed at reducing LWBS rates. Machine Learning (ML) models that dynamically update these risk predictions as patients experience more time waiting were developed and validated, in order to improve the prediction accuracy and correctly identify more patients who LWBS.
Methods: The study was deemed quality improvement by the institutional review board, and collected all patient visits to the ED of a large academic medical campus over 24 months.

Background: Frailty is a dynamic condition that may affect mental health. This study aimed to investigate the associations of frailty and its changes with the risks of depressive symptoms across multiple regions in aging populations.
Methods: Data were drawn from five cohort studies in the United States, England, Europe, China, and Mexico.
Predicting In-Hospital Cardiac Arrest Using Machine Learning Models: Protocol for a Scoping Review.

Background: In-hospital cardiac arrest (IHCA) remains a public health conundrum with high morbidity and mortality rates. While early identification of high-risk patients could enable preventive interventions and improve survival, evidence on the effectiveness of current prediction methods remains inconclusive. Limited research exists on patients' prearrest pathophysiological status and predictive and prognostic factors of IHCA, highlighting the need for a comprehensive synthesis of predictive methodologies.

Purpose: Expanding high-risk human papillomavirus (HPV) vaccine coverage in resource-constrained settings is critical to bridging the cervical cancer gap and achieving the global action plan for elimination. Mobile health (mHealth) technology via short message services (SMS) has the potential to improve HPV vaccination uptake. The mHealth-HPVac study evaluated the effectiveness of mHealth interventions in increasing HPV vaccine uptake among mothers of unvaccinated girls aged 9-14 years in Lagos, Nigeria.
