Secretory IgA modifies the association between early-life gut microbiota trajectories and childhood nonatopic wheeze.

Aims: Wheezing in childhood is common and evidence is accumulating for the role of the gut microbiome in the development of atopic wheeze. Changes to the early-life gut microbiota and secretory IgA (SIgA) production have been linked to childhood disease; however, their connection to nonatopic wheeze is unknown. The objectives of the present study were to evaluate the relationships between early-life gut microbiota trajectories, SIgA and childhood nonatopic wheeze.

Saturated fatty acids induce lipotoxicity in lymphatic endothelial cells contributing to secondary lymphedema development.

Lymphedema is a chronic lymphatic disorder characterized by persistent tissue swelling, pain, and recurrent infections, often secondary to cancer treatment, surgery, or obesity. Obesity-associated increases in saturated fatty acids (SFAs) have been linked to lipotoxicity. In this study, patients with secondary lymphedema showed a significantly lower plasma polyunsaturated to saturated fatty acid (PUFA/SFA) ratio compared to BMI-matched controls.

The effects of docosahexaenoic acid (DHA) on plasma cytokines, oxylipins, and tumor-infiltrating lymphocytes from women with breast cancer undergoing neoadjuvant chemotherapy in the DHA-WIN trial.

Clinical trials on docosahexaenoic acid (DHA) supplementation and immune changes during breast cancer neoadjuvant chemotherapy (NAC) are limited. This study evaluated the impact of DHA supplementation during NAC on systemic and tumor immune modulation by assessing plasma inflammatory and cardiac damage markers, tumor-infiltrating lymphocyte (TIL) proportions, and n-6- and n-3-derived oxylipins produced in response to an ex vivo immune challenge. Venous blood was collected at baseline, 9, and 15 weeks during NAC from participants in the DHA for Women with Breast Cancer in the Neoadjuvant Setting (DHA-WIN) trial, which compared DHA-enriched algae (4.

Perspective: Implications of Docosahexaenoic Acid and Eicosapentaenoic Acid Supplementation on the Immune System during Cancer Chemotherapy: Perspectives from Current Clinical Evidence.

Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs) with pleiotropic effects on the immune system. Although several preclinical studies support their potential to enhance cancer treatment efficacy, this has not yet been translated into clinical studies. Currently, there are no official recommendations for n-3 LCPUFAs supplementation during cancer chemotherapy.

Impulsive behavior is associated with less favorable dietary intake and cardiometabolic profile in adolescents with obesity.

Background: Unhealthy lifestyle behaviors are important determinants of cardiometabolic health in pediatric obesity. Psychological factors influence decision-making and may influence lifestyle behaviors. Decision-making can be assessed using the delay discounting (DD) method, which assesses the preference for immediate over delayed rewards.

Safety and efficacy of docosahexaenoic acid supplementation during neoadjuvant breast cancer therapy: Findings from the phase II, double-blind, randomized controlled DHA-WIN trial.

There is limited clinical evidence of docosahexaenoic acid (DHA) efficacy during breast cancer neoadjuvant chemotherapy (NAC). This randomized, double-blind, placebo-controlled trial aimed to investigate the safety and efficacy of DHA supplementation in breast cancer patients undergoing NAC. Participants (n = 49) were assigned to receive either DHA 4.

Docosahexaenoic acid (DHA) supplementation attenuates changes in the concentration, phenotype, and response of immune peripheral blood cells in breast cancer patients undergoing neoadjuvant therapy. Secondary findings from the DHA-WIN trial.

Background: Breast cancer neoadjuvant therapy may negatively impact the immune system. As a secondary outcome of the docosahexaenoic acid (DHA) for women with breast cancer in the neoadjuvant setting (DHA-WIN trial), we sought to assess the effects of an intervention with DHA on parameters of immune function of women undergoing neoadjuvant therapy.

Methods: Women with early-stage breast cancer in the neoadjuvant setting were recruited for the DHA-WIN trial and randomly assigned to receive either 4.

Exploratory outcomes of the DHA WIN randomized controlled trial: Supplementing women with docosahexaenoic acid did not reduce the impact of neoadjuvant breast cancer chemotherapy on quality of life or exercise behaviour.

Supplementation of omega-3 (n-3) polyunsaturated fatty acids has been associated with reduced side effects and improved quality of life (QoL) in breast cancer patients receiving chemotherapy. The current study reports secondary outcomes from the DHA WIN randomized controlled trial which was designed to evaluate docosahexaenoic acid (DHA) supplementation (4.4 g/day) in conjunction with six cycles of neoadjuvant chemotherapy (NAC) (3 weeks/cycle) in women with non-metastatic breast cancer (n = 49).

A Randomized Crossover Fiber Intervention Study in Prader-Willi Syndrome: Insights into Metabolic and Microbiota Shifts.

Context: While increased fiber intake may benefit appetite and metabolism in the general population, its effects in individuals with Prader-Willi Syndrome (PWS), a condition characterized by hyperphagia, obesity and metabolic dysregulation, remain to be explored.

Objectives: This study assessed the effects of a fiber intervention on hyperphagia, metabolic health, and gut microbiota in individuals with PWS, and explored associations between changes in health markers and shifts in microbiota.

Methods: Participants received either a high-dose fiber intervention (35g/day) or a control for 3 weeks.

Gut microbiota metabolites, secretory immunoglobulin A and Bayley-III cognitive scores in children from the CHILD Cohort Study.

Background: Dysbiosis of the gut microbiota has been demonstrated in neurodevelopmental disorders but the underlying mechanisms that may explain these associations are poorly understood. Gut secretory immunoglobulin A (SIgA) binds pathogenic microbes, preventing mucosal penetration. Gut microbes also influence SIgA production and its binding characteristics through short-chain fatty acid (SCFA) metabolites, allowing them to regulate the immune response.

Cardiometabolic benefits of a non-industrialized-type diet are linked to gut microbiome modulation.

Industrialization adversely affects the gut microbiome and predisposes individuals to chronic non-communicable diseases. We tested a microbiome restoration strategy comprising a diet that recapitulated key characteristics of non-industrialized dietary patterns (restore diet) and a bacterium rarely found in industrialized microbiomes (Limosilactobacillus reuteri) in a randomized controlled feeding trial in healthy Canadian adults. The restore diet, despite reducing gut microbiome diversity, enhanced the persistence of L.

Determinants of maternal and infant omega-3 status at 3 months postpartum: findings from the APrON longitudinal cohort study.

Background: Omega-3 long-chain-polyunsaturated fatty acids (LCPUFAs) are important dietary components for maternal and infant health during pregnancy and lactation.

Objectives: This study investigated determinants of maternal and infant LCPUFAs status at 3 mo postpartum and the relationship between maternal serum, maternal milk, and infant LCPUFAs.

Methods: This cross-sectional study included mothers (n = 1481) and their offspring (n = 526) at 3 mo postpartum from the Alberta Pregnancy Outcomes and Nutrition (APrON) cohort.

The Novel Lipid Emulsion Vegaven Is Well Tolerated and Elicits Distinct Biological Actions Compared With a Mixed-Oil Lipid Emulsion Containing Fish Oil: A Parenteral Nutrition Trial in Piglets.

Background: Vegaven is a novel lipid emulsion for parenteral nutrition (PN) based on 18-carbon n-3 (ω-3) fatty acids, which elicits liver protection via interleukin-10 (IL-10) in the murine model of PN.

Objectives: In a preclinical model of PN in neonatal piglets, Vegaven was tested for efficacy and safety and compared with a mixed-oil lipid emulsion containing fish oil (SMOFlipid).

Methods: Male piglets 4-5 d old were randomly allocated to isocaloric isonitrogenous PN for 14 d, which varied only by the type of lipid emulsion (Vegaven, n = 8; SMOFlipid, n = 8).

Effects of high-intensity interval training on cardiometabolic biomarkers in patients with prostate cancer undergoing active surveillance: a randomized controlled trial.

Purpose: To report the effects of a 12-week high-intensity interval training (HIIT) program on cardiometabolic biomarkers in patients with prostate cancer on active surveillance (AS) from the Exercise During Active Surveillance for Prostate Cancer (ERASE) Trial.

Methods: Fifty-two men with prostate cancer on AS were randomized to either an exercise (HIIT; n = 26) or usual care (UC; n = 26) group. The HIIT intervention consisted of progressive, supervised, aerobic HIIT at an intensity of 85 to 95% VO for 28 to 40 min per session performed three times/week for 12 weeks.

Cardiometabolic Health in Adolescents with Obesity: The Role of Protein Intake, Diet Quality, and Physical Activity.

Although adolescents with obesity have an increased risk of cardiometabolic disease, a subset maintains a healthy cardiometabolic profile. Unhealthy lifestyle behaviors may determine cardiometabolic risk. We aimed to characterize the lifestyle behaviors of adolescents with obesity, compare differences between metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO), and assess associations between lifestyle behaviors and cardiometabolic profiles.

Maternal pre-pregnancy BMI influences the associations between bisphenol and phthalate exposures and maternal weight changes and fat accumulation.

Background: Bisphenols and phthalates are two classes of endocrine-disrupting chemicals (EDCs) thought to influence weight and adiposity. Limited research has investigated their influence on maternal weight changes, and no prior work has examined maternal fat mass. We examined the associations between exposure to these chemicals during pregnancy and multiple maternal weight and fat mass outcomes.

Maternal pre-pregnancy diet and prenatal depression: the mediating role of pre-pregnancy weight status and prenatal inflammation.

Depression is a common prenatal psychological complication. We aimed to investigate if maternal pre-pregnancy diet can impact prenatal depressive symptoms and the mediating role of pre-pregnancy BMI and inflammation. We used data ( 1141) from the Alberta Pregnancy Outcomes and Nutrition cohort study.

Association of Human Milk Fatty Acid Composition with Maternal Cardiometabolic Diseases: An Exploratory Prospective Cohort Study.

Human milk fatty acids derive from maternal diet, body stores, and mammary synthesis and may reflect women's underlying cardiometabolic health. We explored whether human milk fatty acid composition was associated with maternal cardiometabolic disease (CMD) during pregnancy and up to 5 years postpartum. We analyzed data from the prospective CHILD Cohort Study on 1,018 women with no preexisting CMD who provided breast milk samples at 3-4 months postpartum.

Dichotomous effect of dietary fiber in pediatrics: a narrative review of the health benefits and tolerance of fiber.

Dietary fibers are associated with favorable gastrointestinal, immune, and metabolic health outcomes when consumed at sufficient levels. Despite the well-described benefits of dietary fibers, children and adolescents continue to fall short of daily recommended levels. This gap in fiber intake (i.

Maternal smoking during pregnancy increases the risk of gut microbiome-associated childhood overweight and obesity.

Childhood obesity is linked to maternal smoking during pregnancy. Gut microbiota may partially mediate this association and could be potential targets for intervention; however, its role is understudied. We included 1,592 infants from the Canadian Healthy Infants Longitudinal Development Cohort.

Pre-labor and post-labor cesarean delivery and early childhood adiposity in the Canadian Healthy Infant Longitudinal Development (CHILD) Cohort Study.

Background/objectives: Delivery by cesarean section (CS) compared to vaginal delivery has been associated with increased risk of overweight in childhood. Our study examined if the presence or absence of labor events in CS delivery altered risk of overweight in early childhood (1-5 years) compared to vaginal delivery and if this association differed according to infant sex.

Subjects/methods: The study included 3073 mother-infant pairs from the CHILD Cohort Study in Canada.

The metabolic load-capacity model and cardiometabolic health in children and youth with obesity.

Background: The metabolic load-capacity index (LCI), which represents the ratio of adipose to skeletal muscle tissue-containing compartments, is potentially associated with cardiometabolic diseases.

Objectives: To examine the associations between the LCI and cardiometabolic risk factors in children and youth with obesity.

Methods: This is a cross-sectional study including 10-18 years-old participants with a BMI of ≥95 .

Maternal pre-pregnancy weight status and gestational weight gain in association with child behavior: The mediating role of prenatal systemic inflammation.

Background And Aims: Maternal pre-pregnancy obesity and excessive gestational weight gain (EGWG) may predispose children to behavioral problems through increased prenatal inflammation. We investigated the association between maternal body mass index (BMI) and gestational weight gain (GWG), and child behavioral problems (primary aim), and the mediating role of prenatal inflammation (secondary aim).

Methods: We used self-reported pre-pregnancy BMI and estimated-GWG data (N = 1137) from a longitudinal cohort study.
