Association Between Circulating Fatty Acids and Blood Pressure: A Review.

Curr Nutr Rep

January 2025

Endocrinology and Nephrology Research Axis, CHU de Québec Research Center, CHU of Quebec-Laval University, CHUL - 2705, Boulevard. Laurier, Quebec, G1V 4G2, Canada.

Purpose Of Review: High blood pressure (BP) or hypertension (HTN) remains key risk factors for cardiovascular disease (CVD). Circulating fatty acids (FAs) in the blood can affect directly cardiovascular hemodynamics and serves as building blocks for endocrine mediators modifying inflammatory processes and vascular function. This review aims to describe optimal circulating FA profiles for BP to adjust dietary recommendations for HTN prevention.

Aims/hypothesis: A positive association between sugar-sweetened beverages (SSBs) and diabetes risk has been shown, with inconsistent evidence between artificially sweetened beverages (ASBs) and diabetes. Moreover, it is uncertain if physical activity can mitigate the negative effects of these beverages on diabetes development. Therefore, we aimed to evaluate the independent and joint associations between SSB or ASB consumption and physical activity on the risk of type 2 diabetes.

Background: Adolescent idiopathic scoliosis (AIS) is characterized by an asymmetrical formation of the spine and ribcage. Recent work provides evidence of asymmetrical (right versus left side) paraspinal muscle size, composition, and activation amplitude in adolescents with AIS. Each of these factors influences muscle force generation.

Background: Artificial intelligence (AI) predictive models in primary health care have the potential to enhance population health by rapidly and accurately identifying individuals who should receive care and health services. However, these models also carry the risk of perpetuating or amplifying existing biases toward diverse groups. We identified a gap in the current understanding of strategies used to assess and mitigate bias in primary health care algorithms related to individuals' personal or protected attributes.

We aimed to understand how experiences with vaccine-related information and communication challenges during the COVID-19 pandemic impacted motivations and behaviors among Canadian adults regarding future vaccines. Semi-structured interviews were conducted with participants purposively selected to ensure diversity in age, sex at birth, self-identified gender, and region. Data were analyzed using thematic analysis; findings were mapped to the Information-Motivation-Behavioral Skills Model focusing on factors affecting vaccine hesitancy and uptake.

Development and usability testing of a multifaceted intervention to reduce low-value injury care.

BMC Health Serv Res

January 2025

Population Health and Optimal Health Practices Research Unit, Centre de Recherche du CHU de Québec (Hôpital de L'Enfant-Jésus), Université Laval, 1401, 18e rue, Québec, Qc, Canada.

Background: Multifaceted interventions that address barriers and facilitators have been shown to be most effective for increasing the adoption of high-value care, but there is a knowledge gap on this type of intervention for the de-implementation of low-value care. Trauma is a high-risk setting for low-value care, such as unnecessary diagnostic imaging and the use of specialized resources. The aim of our study was to develop and assess the usability of a multifaceted intervention to reduce low-value injury care.

Usefulness of Aortic Valve Calcification in Patients With Low-Flow Aortic Stenosis.

Circ Cardiovasc Imaging

January 2025

Department of Cardiology, Odense University Hospital, Denmark (N.S.B.M., J.S.D., M.A., A.H., R.C.-S., J.E.M., K.A.Ø., M.-A.C.).

Background: Aortic valve calcification (AVC) has been shown to be a powerful assessment of aortic stenosis (AS) severity and a predictor of adverse outcomes. However, its accuracy in patients with low-flow AS has not yet been proven. The objective of the study was to assess the predictive value of AVC in patients with classical low-flow (CLF, that is, low-flow reduced left ventricular ejection fraction) or paradoxical low-flow (PLF, that is, low-flow preserved left ventricular ejection fraction) AS.

: Binge eating (BE) is associated with physical and psychological consequences, such as obesity and reduced quality of life. The relationship between binge eating and childhood experiences of interpersonal trauma has been explored, yet few studies focus on the processes that may explain this association. In this regard, some personality traits and maladaptive cognitive-emotional regulation may help explain this relationship, as they have been associated, respectively, with BE and childhood interpersonal trauma.

Mercury and Arctic Char Gill Microbiota Correlation in Canadian Arctic Communities.

Microorganisms

November 2024

Institute of Integrative and Systems Biology, Laval University, Quebec, QC G1V 0A6, Canada.

Arctic char is a top predator in Arctic waters and is threatened by mercury pollution in the context of changing climate. Gill microbiota is directly exposed to environmental xenobiotics and play a central role in immunity and fitness. Surprisingly, there is a lack of literature studying the effect of mercury on gill microbiota.

Ten coordination compounds, [Cu(L)Cl] (), [Cu(L)NO] (), [Cu(L)Cl] (C3), [Cu(L)NO] (), [Cu(L)Cl] (), [Cu(L)NO] (), [Cu(L)NO] (), [Cu(L)Cl] (), [Cu(L)Cl] (), and [Cu(L)NO] (), containing pyridine derivatives of -methoxyphenyl-thiosemicarbazones were synthesized and characterized. The molecular structure of four compounds was investigated using single crystal X-ray diffraction. Spectral analysis techniques such as FT-IR, H NMR, C NMR, elemental analysis, and molar conductivity were used for all the synthesized compounds.

Parkinson's disease (PD) is a prevalent neurodegenerative disorder characterized by the degeneration of dopamine neurons in the substantia nigra pars compacta, leading to motor and non-motor symptoms. While motor symptoms such as rigidity, tremor, bradykinesia/akinesia, and postural instability are well-recognized, non-motor symptoms including cognitive decline, depression, and anxiety also significantly impact patients' quality of life. Preclinical research utilizing animal models has been instrumental in understanding PD pathophysiology and exploring therapeutic interventions.

Promising clinical evidence suggests that psychedelic compounds, like lysergic acid diethylamide (LSD), have therapeutic value for treatment of psychiatric disorders. However, they often produce hallucinations and dissociative states, likely mediated by the serotonin (5-HT) receptor 5-HT, raising challenges regarding therapeutic scalability. Given the reported antipsychotic effects of cannabidiol (CBD) and its promiscuous binding at many receptors, we assessed whether CBD could modulate 5-HT signaling.
