Grape polyphenols corrects ageing-related detriments in neutrophil functionality via modulation of specific molecular targets

Oxidative stress and inflammation are intricately interlinked as aetiological factors in the context of ageing and chronic disease-related accelerated ageing. Previous research by our group has highlighted the anti-oxidant and anti-inflammatory potential of grape-derived polyphenols in the context of acute inflammation and oxidative stress. The aim here was to add to this by assessing efficacy of the treatment (acutely) to address ageing-associated cumulative pro-oxidant and pro-inflammatory changes in an in vitro model. Blood from young and aged humans was analysed for baseline oxidative stress and inflammatory status. Isolated neutrophils were acutely exposed to the polyphenol treatment in vitro. The chemokinetic capacity of treated and control neutrophils in response to fMLP was subsequently determined in a Dunn chamber, using live cell imaging. Neutrophils were also analysed for the expression of selected molecular markers associated with functional capacity and oxidative stress. Results indicate that the aged population had significantly worse oxidative stress and inflammatory profiles (higher plasma conjugated dienes and MPO) than young controls. Neutrophils isolated from both young and aged individuals had improved chemokinetic accuracy and capacity after in vitro polyphenol treatment. Additionally, increased shedding of CD16 and expression of CD66b suggested sites via which the polyphenol achieved improved neutrophil motility. We conclude that grape seed-derived polyphenols facilitated improved neutrophil functionality by acting on the molecular targets elucidated here.     

Digital Promotion of Energy Drinks to Young Adults Is More Strongly Linked to Consumption Than Other Media

Objective

To examine whether digital marketing strategies are more strongly associated with energy drink use than other marketing and whether Theory of Planned Behavior (TPB) constructs mediated the effects of digital marketing on energy drink use.

Health-related quality of life in mothers of children with epilepsy: 10 years after diagnosis

Purpose

Epilepsy in childhood extends far beyond seizures and affects child and parental well-being. The long-term impact of childhood-onset epilepsy on parental well-being is unknown. This study assessed health-related quality of life (HRQOL) in mothers 10 years after their child’s diagnosis of epilepsy.

Methods

Data come from the Health-Related Quality of Life in Children with Epilepsy Study, a multicenter prospective cohort study of children with newly diagnosed epilepsy. Mothers completed a mailed questionnaire at the 10-year follow-up, which included the Short-Form Health Survey (SF-12-v2) to evaluate the physical and mental health components of their HRQOL. Block-wise linear regressions identified child/epilepsy, maternal/family, and maternal psychosocial factors associated with mothers’ HRQOL.

Results

A total of 159 mothers participated in this study (46% of the sample assessed at baseline). At follow-up, 69% of youth had been seizure free for the past 5 years. Mothers scored similarly to population norms (mean: 50, SD: 10) on the mental health subscale (mean: 49.5, SD: 9.3) and significantly better on the physical health subscale (mean: 53.0, SD: 7.6). Better family resources were associated with higher (better) scores on the physical health subscale (B?=?0.20; 95% CI 0.03, 0.36). Better family functioning (B?=?0.34; 95% CI 0.06, 0.62), fewer maternal depressive symptoms (B?=?0.33; 95% CI 0.20, 0.47), and perception of less stress (B?=?0.70; 95% CI 0.52, 0.88) were associated with higher (better) scores on the mental health subscale.

Conclusion

Ten years after the diagnosis of epilepsy in children, the HRQOL of mothers was similar to reports from women in the general population. This study identified factors contributing to better maternal HRQOL and highlights the importance of family environment over epilepsy-related variables.
