Intestinal Cells-on-Chip for Permeability Studies.

Micromachines (Basel)

November 2024

Department of Metabolic Health Research, Netherlands Organisation for Applied Scientific Research (TNO), 2333 BE Leiden, The Netherlands.

Background: To accurately measure permeability of compounds in the intestine, there is a need for preclinical in vitro models that accurately represent the specificity, integrity and complexity of the human small intestinal barrier. Intestine-on-chip systems hold considerable promise as testing platforms, but several characteristics still require optimization and further development.

Methods: An established intestine-on-chip model for tissue explants was adopted for intestinal cell monolayer culture.

The Need for a Cancer Exposome Atlas: A Scoping Review.

JNCI Cancer Spectr

December 2024

Gangarosa Department of Environmental Health, Rollins School of Public Health, Emory University, Atlanta, Georgia, USA.

Background: Despite advances in understanding genetic susceptibility to cancer, much of cancer heritability remains unidentified. At the same time, the makeup of industrial chemicals in our environment only grows more complex. This gap in knowledge on cancer risk has prompted calls to expand cancer research to the comprehensive, discovery-based study of non-genetic environmental influences, conceptualized as the "exposome.

Background: Air pollution is a major risk factor for cardiovascular diseases and contributes to health disparities, particularly among minority ethnic groups, who often face higher exposure levels. Knowledge on whether the effect of air pollution on cardiovascular diseases differs between ethnic groups is crucial for identifying mechanisms underlying health disparities, ultimately informing targeted public health strategies and interventions. We explored differences in associations between air pollution and ischemic stroke and ischemic heart disease (IHD) for the six largest ethnic groups in the Netherlands.

Influence of the Enterovirus 71 Vaccine and the COVID-19 Pandemic on Hand, Foot, and Mouth Disease in China Based on Counterfactual Models: Observational Study.

JMIR Public Health Surveill

December 2024

School of Disaster and Emergency Medicine, Tianjin University, No. 92, Weijin Road, Nankai District, Tianjin, 300072, China, 86 02287370177307.

Background: Hand, foot, and mouth disease (HFMD) is a highly contagious viral illness. Understanding the long-term trends of HFMD incidence and its epidemic characteristics under the circumstances of the enterovirus 71 (EV71) vaccination program and the outbreak of COVID-19 is crucial for effective disease surveillance and control.

Objective: We aim to give an overview of the trends of HFMD over the past decades and evaluate the impact of the EV71 vaccination program and the COVID-19 pandemic on the epidemic trends of HFMD.

Recently, the Netherlands has shifted toward more welfare-friendly broiler production systems using slower-growing broiler breeds. Early post-hatch feeding (EF) is a dietary strategy that is currently used in commercial broiler production to modulate the gut microbiota and improve performance and welfare. However, there is a knowledge gap in how both breed and EF and their interplay affect gut microbiota composition and diversity, inflammatory status, and broiler behavior.

Article Synopsis
  • Toxicology and epidemiology are crucial public health fields that help investigate the health impacts of toxic substance exposure, with various frameworks for evidence integration evolving since 2011.
  • Collaboration among scientists from different disciplines, such as toxicologists, epidemiologists, and risk assessors, is essential for effective risk assessment aligned with regulatory goals.
  • Implementing transparent literature searches, systematic protocols for evidence collection, tailored quality assessment tools, and the Adverse Outcome Pathway framework can enhance the understanding and integration of toxicological data.

Article Synopsis
  • The implementation of Safe and Sustainable by Design (SSbD) and grouping approaches requires effective and cost-efficient assays for early hazard screening, particularly for nanomaterials (NMs).
  • Oxidative potential (OP), indicating a substance’s ability to produce harmful reactive oxygen species (ROS), is a key factor in assessing potential oxidative damage, often measured using the ferric reducing ability of serum (FRAS) assay.
  • A modified 96-well format of the FRAS assay enhances user-friendliness and throughput, allowing for simultaneous screening of multiple NMs, although it shows slightly lower precision than the original cuvette-based method while still maintaining acceptable variability in results.

The effects of ultrafine particle (UFP) inhalation on neurodevelopment, especially during critical windows of early life, remain largely unexplored. The specific time windows during which exposure to UFP might be the most detrimental remain poorly understood. Here, we studied early-life exposure to clean ultrafine carbonaceous particles (UFP) and neurodevelopment and central nervous system function in offspring.

Article Synopsis
  • The study investigates the link between residential greenspace and the impact of COVID-19 on health, focusing on Danish adults 50 and older during the pandemic.* -
  • Researchers found that increased greenspace was associated with lower rates of COVID-19 infection, hospitalization, and mortality, especially among vulnerable groups like the elderly and those with chronic illnesses.* -
  • Health impact assessments suggested that enhancing local greenspace could have potentially prevented 8-14% of COVID-19 cases in the population studied, indicating benefits of greening initiatives.*

Article Synopsis
  • Benzene is linked to human carcinogenicity, notably causing acute myeloid leukemia, with limited evidence for lung cancer connections.
  • A systematic review and meta-analysis were conducted on occupational benzene exposure and lung cancer risk, involving 13 studies with over 366,000 participants.
  • Results indicated a slight elevation in lung cancer risk associated with occupational benzene exposure, with higher risks observed in well-exposed, high-quality studies that included both genders, concluding that there is a positive association between benzene exposure and lung cancer risk.

Literature indicates a potential association between dairy consumption and risk of Parkinson´s disease (PD), especially among men, yet the results remain inconclusive. We investigated this association in a large prospective European cohort. Dietary and non-dietary data was collected from 183,225 participants of the EPIC-for-Neurodegenerative-Diseases (EPIC4ND) cohort, a sub-cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort.
