Introduction: Globally, the prevalence of undernutrition is highest in the sub-Saharan African region with over a third of the world's stunted children residing in this region. Many studies have explored child nutrition in sub-Saharan Africa, but they often overlook the intricate nuances of maternal knowledge. We examined the association between maternal nutritional knowledge and childhood nutritional outcomes.

Re-thinking the link between exposure to mercury and blood pressure.

Arch Toxicol

January 2025

Chemical and Environmental Toxicology Program, Department of Biology, University of Ottawa, 30 Marie Curie, Ottawa, ON, K1N 6N5, Canada.

Hypertension or high blood pressure (BP) is a prevalent and manageable chronic condition which is a significant contributor to the total global disease burden. Environmental chemicals, including mercury (Hg), may contribute to hypertension onset and development. Hg is a global health concern, listed by the World Health Organization (WHO) as a top ten chemical of public health concern.

The integration of psychedelic substances into modern Western therapeutic practice has sparked a critical examination of many topics including: efficacy of psychedelics to treat mental health diagnoses without psychotherapeutic intervention, what models of therapy to use, and ethical implications related to altered states of consciousness. Of utmost concern are issues of power dynamics leading to incidents of sexual abuse. These issues underscore the importance of understanding therapeutic dynamics within the context of psychedelic-assisted therapy.

Lanthanide-based Single-Molecule Magnets (SMMs) with optical and magnetic properties provide a means to understand intrinsic energy levels of 4f ions and their influence on optical and magnetic behaviour. Fundamental understanding of their luminescent and slow relaxation of the magnetization behaviour is critical for targeting and designing SMMs with multiple functionalities. Herein, we seek to investigate the role of Dy coordination environment and fine electronic structure on the slow magnetic relaxation and luminescence thermometry.

Interference of surface plasmons has been widely utilized in optical metrology for applications such as high-precision sensing. In this paper, we introduce a surface plasmon interferometer with the potential to be arranged in arrays for parallel multiplexing applications. The interferometer features two grating couplers that excite surface plasmon polariton (SPP) waves traveling along a gold-air interface before converging at a gold nanoslit where they interfere.

Background: Cardiogenic shock (CS) is a heterogeneous clinical syndrome, making it challenging to predict patient trajectory and response to treatment. This study aims to identify biological/molecular CS subphenotypes, evaluate their association with outcome, and explore their impact on heterogeneity of treatment effect (ShockCO-OP, NCT06376318).

Methods: We used unsupervised clustering to integrate plasma biomarker data from two prospective cohorts of CS patients: CardShock (N = 205 [2010-2012, NCT01374867]) and the French and European Outcome reGistry in Intensive Care Units (FROG-ICU) (N = 228 [2011-2013, NCT01367093]) to determine the optimal number of classes.

Experimental investigations of colloid-associated metal mobility in mine-impacted wetland sediment.

Heliyon

January 2025

Department of Earth Sciences, Carleton University, 1125 Colonel By Dr, Ottawa, ON, K1S 5B6, Canada.

Metal mining operations can release toxic metals to surrounding environments where site-specific conditions control the movement of contaminants. Colloid-facilitated transport, the transport of contaminants with small, mobile particles, has been recognized as a potential contaminant transport vector in groundwater, but it remains unclear under what conditions it is important and whether neutral, metal-rich mine drainage from legacy mining impacts this transport vector. This work presents a set of laboratory column experiments that study the effect of colloids on metal mobility in saturated, wetland sediment that has been receiving neutral mine drainage for nearly a century, using mixed and single metal input solutions at neutral pH.

The simultaneous occurrence of primary headaches and temporomandibular disorders can pose a challenge in determining the best clinical management of patients. Therefore, we aimed to summarize evidence regarding the risk and prevalence of temporomandibular disorders (TMDs) in migraine and tension-type headaches (TTH) patients. Cross-sectional studies published in English comparing the presence of TMDs in adults with TTH or migraine to subjects without headaches were included, International Classification of Orofacial Pain, Diagnostic Criteria for Temporomandibular Disorders or Research Diagnostic Criteria for Temporomandibular Disorders, and large epidemiological studies (sensitive diagnostic criteria (SDC)).

Background: Lung cancer is one of the malignant tumors with the highest morbidity and mortality rates worldwide, seriously threatening human health. Non-small cell lung cancer (NSCLC) accounts for more than 85% of all lung cancer cases. STMN1 is a microtubule depolymerizing protein widely present in the cytoplasm and its expression level is associated with the prognosis of NSCLC patients.

Article Synopsis
  • This systematic review investigates how body composition, particularly skeletal muscle mass, impacts vascular health measures like arterial stiffness and structure.
  • Researchers conducted a thorough literature search and included 15 observational studies with over 21,000 participants, assessing various vascular health indices.
  • The findings show that higher fat-free mass correlates positively with carotid artery thickness, while body fat percentage is linked to arterial stiffness, indicating a need for further research on specific body composition factors and their health implications.
