Modified Delphi Consensus on Interventions for Acute Radiation Dermatitis in Breast Cancer: A Canadian Expert Perspective.

Acute radiation dermatitis (ARD) is a prevalent adverse effect of radiotherapy in patients with breast cancer, and there is a lack of high-quality data regarding its prevention and management. This study employs a systematic and iterative process to compile the perspectives of Canadian radiation oncology, nursing, and dermatology experts, aiming to establish consensus-based recommendations for the prevention and management of ARD in breast cancer patients. A modified Delphi consensus was conducted with the participation of 19 experts from across Canada.

The role of meal timing in appetitive responses to acute exercise in adolescents with and without obesity: A systematic review and meta-analysis.

Physical activity has been shown to improve various aspects of metabolic health and is frequently applied as an intervention in the management and prevention of overweight/obesity. Chrono-exercise can be studied in relation to time of day and timing in relation to a meal, which encompasses chronology and duration of the temporal interval, but the latter has received limited attention to date. This brief review and meta-analysis investigates whether the timing of a meal subsequent to acute exercise, in children and adolescents with and without overweight/obesity, moderates eating behaviour and appetite.

Monocytic reactive oxygen species-induced T cell apoptosis impairs cellular immune response to SARS-CoV-2 mRNA vaccine.

Background: We have recently shown that, during acute severe COVID-19, SARS-CoV-2 spike protein (S) induces a cascade of events resulting in T cell apoptosis. Indeed, by neutralizing the protease activity of its receptor, ACE2, S induces an increase in circulating Angiotensin II (AngII), resulting in monocytic release of reactive oxygen species (ROS) and programmed T cell death.

Objective: Here, we tested whether SARS-CoV-2 mRNA vaccines, known to cause the circulation of the vaccine antigen, S-protein receptor binding domain (RBD), might trigger the same cascade.

A ten-year prospective randomized trial comparing non-operative treatment to hook plate fixation for Rockwood III acromio-clavicular dislocation.

Background: Despite new modern surgical techniques, no short-term functional differences have been demonstrated between operative and non-operative treatment for acute acromio-clavicular (AC) dislocations Rockwood III-V. Few studies describe the long-term clinical and radiological results of these lesions. We aim to compare the one- and ten-year outcome of patients either treated non-operatively or with hook plate fixation for Rockwood III AC lesions.

Transformation and articulation of clinical data to understand students' clinical reasoning: a scoping review.

Background: Despite the importance of effective educational strategies to promote the transformation and articulation of clinical data while teaching and learning clinical reasoning, unanswered questions remain. Understanding how these cognitive operations can be observed and assessed is crucial, particularly considering the rapid growth of artificial intelligence and its integration into health education. A scoping review was conducted to map the literature regarding educational strategies to support transformation and articulation of clinical data, the learning tasks expected of students when exposed to these strategies and methods used to assess individuals' proficiency METHODS: Based on the Joanna Briggs Institute methodology, the authors searched 5 databases (CINAHL, MEDLINE, EMBASE, PsycINFO and Web of Science), ProQuest Dissertations & Theses electronic database and Google Scholar.

Review - Insect farming for food and feed in the Global South: Focus on black soldier fly production.

Clear differences exist between the Global South and the Global North with respect to economic development. The majority of small and medium-sized insect production farms are located in Africa, Asia, and Latin America, which face challenges to food production and organic waste management in general. These regions have a long history of insect use, as well as environmental advantages, making production of insects in general - and the black soldier fly in particular - a promising option for sustainable food production and organic waste management.

Developmental exposure to legacy environmental contaminants, medial temporal lobe volumes and spatial navigation memory in late adolescents.

Exposure to lead, mercury, and polychlorinated biphenyls (PCBs) has been causally linked to spatial memory deficits and hippocampal changes in animal models. The Inuit community in Northern Canada is exposed to higher concentrations of these contaminants compared to the general population. This study aimed to 1) investigate associations between prenatal and current contaminant exposures and medial temporal brain volumes in Inuit late adolescents; 2) examine the relationship between these brain structures and spatial memory; and 3) assess the mediating role of brain structures in the association between contaminant exposure and spatial memory.

Addressing evidence needs during health crises in the province of Quebec (Canada): a proposed action plan for rapid evidence synthesis.

Background: The COVID-19 pandemic necessitated the rapid availability of evidence to respond in a timely manner to the needs of practice settings and decision-makers in health and social services. Now that the pandemic is over, it is time to put in place actions to improve the capacity of systems to meet knowledge needs in a situation of crisis. The main objective of this project was thus to develop an action plan for the rapid syntheses of evidence in times of health crisis in Quebec (Canada).

Species-specific mercury speciation in billfishes and its implications for food safety monitoring and dietary advice.

Humans are exposed to toxic methylmercury mainly by consuming marine fish, in particular top predator species like billfishes or tunas. In seafood risk assessments, mercury is assumed to be mostly present as organic methylmercury in predatory fishes; yet high percentages of inorganic mercury were recently reported in marlins, suggesting markedly different methylmercury metabolism across species. We quantified total mercury and methylmercury concentrations in muscle of four billfish species from the Indian and the Pacific oceans to address this knowledge gap.

Hypertensive Response to Exercise in Normotensive Men and Women with Abdominal Obesity: Association with Subclinical Adverse Cardiac Remodeling.

Hypertensive response to exercise (HRE) is an established risk factor for cardiovascular events. HRE is prevalent among people with excess adiposity. Both obesity and HRE have been individually associated with adverse cardiac remodeling.

Improved Functionality, Quality, and Shelf Life of -Type Camel Sausage Fortified with Spirulina as a Natural Ingredient.

The objective of the present work was to examine the effect of incorporating spirulina powder (SP) in -type sausages made exclusively with camel meat, as well as to evaluate its physicochemical, microbiological, and sensory quality attributes and its prebiotic potential. The final purpose was to offer an innovative meat product to increase camel meat consumption. Several innovative fresh sausage formulations were developed using SP (00, 100, 250, and 500 mg/kg) and stored under vacuum conditions with refrigeration at 1 ± 1 °C for 35 days.

Antimicrobial Peptides from Porcine Blood Cruor Hydrolysates as a Promising Source of Antifungal Activity.

Porcine blood, a significant byproduct of the pork industry, represents a potential source of antimicrobial peptides (AMPs). AMPs offer a promising alternative to chemical antimicrobials, which can be used as natural preservatives in the food industry. AMPs can exhibit both antibacterial and/or antifungal properties, thus improving food safety and addressing the growing concern of antibiotic and antifungal resistance.

Binge eating disorder recognition and stigma among an adult community sample.

Background: Despite being the most prevalent eating disorder, Binge eating disorder (BED) remains largely unrecognized and lacks awareness among the general public, where it is also highly stigmatized. Common stigma surrounding BED includes the belief that individuals with this disorder are responsible for their condition and lack willpower and self-control. Research on BED recognition and stigma among lay adults is scarce.

A multivalent engagement of ENL with MOZ.

The epigenetic cofactor ENL (eleven-nineteen-leukemia) and the acetyltransferase MOZ (monocytic leukemia zinc finger) have vital roles in transcriptional regulation and are implicated in aggressive forms of leukemia. Here, we describe the mechanistic basis for the intertwined association of ENL and MOZ. Genomic analysis shows that ENL and MOZ co-occupy active promoters and that MOZ recruits ENL to its gene targets.

TGFβ1 Restores Energy Homeostasis of Human Trophoblast Cells Under Hyperglycemia In Vitro by Inducing PPARγ Expression, AMPK Activation, and HIF1α Degradation.

Elevated glucose levels at the fetal-maternal interface are associated with placental trophoblast dysfunction and increased incidence of pregnancy complications. Trophoblast cells predominantly utilize glucose as an energy source, metabolizing it through glycolysis in the cytoplasm and oxidative respiration in the mitochondria to produce ATP. The TGFβ1/SMAD2 signaling pathway and the transcription factors PPARγ, HIF1α, and AMPK are key regulators of cell metabolism and are known to play critical roles in extravillous trophoblast cell differentiation and function.

Bone Turnover Markers Predict Changes in Bone Mineral Density in Men Treated with Abaloparatide: Results from ATOM.

Early increases in bone turnover markers (BTMs) in response to anabolic therapy correlate with 18-month bone mineral density (BMD) increases in postmenopausal women with osteoporosis; however, this relationship has not been assessed in men. In this analysis, the correlation between changes from baseline in fasting intact serum procollagen type I N propeptide (PINP) and serum carboxy-terminal cross-linking telopeptide of type I collagen (CTX) at 1, 3, 6, and 12 months and percent increase from baseline in BMD at 12 months in men from the randomized phase 3 ATOM study (NCT03512262) were evaluated using Pearson's correlation coefficients. The uncoupling index (UI), a measure of the balance between markers of bone formation (PINP) and bone resorption (CTX), with positive UI favoring bone formation, was calculated.

TDP-43 Cryptic RNAs in Perry Syndrome: Differences across Brain Regions and TDP-43 Proteinopathies.

Background: Perry syndrome (PS) is a rare and fatal hereditary autosomal dominant neurodegenerative disorder caused by mutations in dynactin (DCTN1). PS brains accumulate inclusions positive for ubiquitin, transactive-response DNA-binding protein of 43 kDa (TDP-43), and to a lesser extent dynactin.

Objectives: Little is known regarding the contributions of TDP-43, an RNA binding protein that represses cryptic exon inclusion, in PS.

Nose-to-brain delivery of DHA-loaded nanoemulsions: A promising approach against Alzheimer's disease.

Reduced docosahexaenoic acid (DHA) concentrations seem to be associated with an increased risk of Alzheimer's disease (AD), and DHA accretion to the brain across the blood-brain-barrier (BBB) can be modulated by various factors. Therefore, there is an urgent need to identify an efficient and non-invasive method to ensure brain DHA enrichment. In the present study, a safe and stable DHA-enriched nanoemulsion, designed to protect DHA against oxidation, was designed and administered intranasally in a transgenic mouse model of AD, the J20 mice.

A case of pityriasis rubra pilaris secondary to ponatinib.

Ponatinib, a tyrosine kinase inhibitor used for chronic myeloid leukemia and acute lymphoblastic leukemia, can cause rare cutaneous side effects. In this case, a 63-year-old woman developed a pityriasis rubra pilaris-like eruption 1 month after starting the drug. The skin reaction improved with dose reduction and recurred more mildly at a lower dose.

The role of gene copy number variation in antimicrobial resistance in human fungal pathogens.

Faced with the burden of increasing resistance to antifungals in many fungal pathogens and the constant emergence of new drug-resistant strains, it is essential to assess the importance of various resistance mechanisms. Fungi have relatively plastic genomes and can tolerate genomic copy number variation (CNV) caused by aneuploidy and gene amplification or deletion. In many cases, these genomic changes lead to adaptation to stressful conditions, including those caused by antifungal drugs.

How peptide migration and fraction bioactivity are modulated by applied electrical current conditions during electromembrane process separation: A comprehensive machine learning-based peptidomic approach.

Industrial wastewaters are significant global concerns due to their environmental impact. Yet, protein-rich wastewaters can be valorized by enzymatic hydrolysis to release bioactive peptides. However, achieving selective molecular differentiation and eventually enhancing peptide bioactivities require costly cascades of membranes.

Virus-mediated delivery of single-chain antibody targeting TDP-43 protects against neuropathology, cognitive impairment and motor deficit caused by chronic cerebral hypoperfusion.

Chronic cerebral hypoperfusion induced by permanent unilateral common carotid artery occlusion in mice was recently found to induce an age-dependent formation of insoluble cytoplasmic TDP-43 aggregates reminiscent of pathological changes found in human vascular dementia. In this model, the gradual deregulation of TDP-43 homeostasis in cortical neurons was associated with marked cognitive and motor deficits. To target the TDP-43-mediated toxicity in this model, we generated an adeno-associated virus vector encoding a single-chain antibody against TDP-43, called scFv-E6, designed for pan-neuronal transduction following intravenous administration.
