Occurrence and enrichment mechanisms of groundwater hexavalent chromium in typical loess area of China.
Environ Pollut

Xi'an Center of Mineral Resources Survey, China Geological Survey, Xi'an, China.
Understanding the geochemical mechanisms governing hexavalent chromium (Cr(VI)) in groundwater is essential for mitigating health risks. However, the processes driving Cr(VI) accumulation and migration in loess regions remain insufficiently understood. This study investigated the occurrence, release, and migration mechanisms of Cr(VI) across different groundwater environmental units (GEUs) in the south-central Loess Plateau, China.

Int J Nurs Knowl
January 2025
Department of Nursing, Federal University of Ceará, Fortaleza, Brazil.
Purpose: This purpose of this article was to use the method of conceptual history to analyze the evolution of the concept of "validity" in nursing diagnoses and to identify key transformations, theoretical influences, and implications for contemporary clinical judgment and decision-making.
Methods: Five stages derivate from the approach proposed by Reinhart Koselleck, including: identify the concept and its relevance, historical contextualization, contextual use, semantic changes over time, and synthesis and interpretation.
Findings: The concept of "validity" in nursing diagnoses is essential for accurate diagnostics, interdisciplinary communication, and evidence-based decision-making, though its interpretation varies due to differing philosophical perspectives and methodological challenges.
Toward Resilient Maternal, Neonatal and Child Health Care: A Qualitative Study Involving Afghan Refugee Women in Pakistan.
Health Serv Insights
January 2025
CRIMEDIM - Center for Research and Training in Disaster Medicine, Humanitarian Aid and Global Health, Università del Piemonte Orientale, Novara, Italy.
Background: Afghan refugees in Pakistan, particularly in Quetta, Balochistan, encounter formidable barriers in accessing maternal, newborn, and child health (MNCH) services. These challenges have been intensified by the COVID-19 pandemic and entrenched systemic health inequities.
Methods: This qualitative study, conducted from February to April 2023, aimed to assess the obstacles within health systems and community environments that hinder MNCH service access among Afghan refugees.
Tumour Mutational Burden and Immune Checkpoint Inhibitor Response in Non-small Cell Lung Cancer: A Continuous Modelling Approach.
Target Oncol
January 2025
College of Medicine and Public Health, Flinders University, Adelaide, SA, Australia.
Background: Tumour mutational burden (TMB) is an established biomarker for patients treated with immune checkpoint inhibitors (ICIs). The optimal TMB cut-off is uncertain. It is also uncertain whether there is a sharp TMB threshold or a more graduated change in clinical outcomes as TMB increases.

Influenza, a highly contagious respiratory viral illness, poses significant global health risks, particularly affecting older and those with chronic health conditions. Influenza viruses, primarily types A and B, are responsible for seasonal human infections and exhibit a propensity for antigenic drift and shift, contributing to seasonal epidemics and pandemics. The severity of influenza varies, but severe cases often lead to pneumonia, acute respiratory distress syndrome, and multiorgan failure.
