Authors: Batenkov K. А. , Fokin A. B. 
Published: April 2024

Objectives. The service level agreement is an important tool used in building reasonable relations between subscribers and operators of telecommunication networks. This includes the quality of services provided. One key component is reliability as assessed by the availability factor. The most suitable model for assessing the reliability of the service provided is a random graph model based on the service contour. This is the set of technical resources involved in the provision of this service. In this formulation, the assessment of the reliability of the service is based on the reliability of elements which constitute the telecommunications network (graph), nodes (vertices) and communication lines (edges). At the same time, the availability factors of nodes and lines are determined by the design features of the distribution environment, as well as the technical means used to organize them. The purpose of this work is to develop an approach to analyzing the reliability of telecommunication networks which support protective switching mechanisms for one protected and one backup sections.Methods. The following methods are used: theory of random graphs, matrices, probabilities and computer modeling.Results. The elements of the route, both basic and reserving, are divided into three groups. The first indicates permanent unchangeable parts of the paths, the second group identifies the reserved sections, and the third group indicates the reserving sections. At the same time, each of the reserved and reserving sections is formed on the basis of specified preferences. They are usually aimed at increasing the resulting reliability, although other rules may be used. In the case of protective switching schemes for one protected section and one backup sections, a variant of forming routes used for further calculations of the reliability indicator is shown.Conclusions. Using the example of a backbone network, the study shows that the use of protective switching mechanisms for the case of one required transmission route demonstrates a significant increase in reliability, with the exception of the use of protective switching in sections. This is primarily due to the topology features of the network under consideration.

Published: April 2024

<p>Given the increase in research suggesting benefit following cognitive training in older adults, researchers have started to investigate the potential moderating role of genetic polymorphisms on transfer effects. The objective of this study was to evaluate the moderating effect of catechol-O-methyltransferase (COMT) and brain-derived neurotrophic factor (BDNF) polymorphisms on transfer effects following a single-domain or multi-domain training intervention in healthy community-dwelling older adults. A total of 104 men and women living in Shanghai were randomized to a multi-domain or a single-domain cognitive training (SDCT) group. COMT rs4818 SNP and the BDNF rs6265 SNP were analyzed from blood. At pre-intervention, post-intervention and at 6-month follow-up, participants completed the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Color-Word Stroop Test (CWST), the Trails Making Test (TMT) and the Visual Reasoning Test (VRT). COMT was found to moderate immediate memory transfer effects following single-domain training only, with G/- carriers displaying greater benefits than C/C carriers. BDNF was found to moderate attention and inhibition independent of the training, with Met/- carriers displaying better performance than Val/Val carriers. Overall, individualizing training methods with full consideration of genetic polymorphisms may promote the maximization of cognitive training benefits.</p>

The association between video game play and cognitive function: Does gaming platform matter?
Authors: Fiocco Alexandra , Huang Vivian , Young Michaelia 
Published: April 2024

<p>Despite consumer growth, few studies have evaluated the cognitive effects of gaming using mobile devices. This study examined the association between video game play platform and cognitive performance. Furthermore, the differential effect of video game genre (action versus nonaction) was explored. Sixty undergraduate students completed a video game experience questionnaire, and we divided them into three groups: mobile video game players (MVGPs), console/computer video game players (CVGPs), and nonvideo game players (NVGPs). Participants completed a cognitive battery to assess executive function, and learning and memory. Controlling for sex and ethnicity, analyses showed that frequent video game play is associated with enhanced executive function, but not learning and memory. MVGPs were significantly more accurate on working memory performances than NVGPs. Both MVGPs and CVGPs were similarly associated with enhanced cognitive function, suggesting that platform does not significantly determine the benefits of frequent video game play. Video game platform was found to differentially associate with preference for action video game genre and motivation for gaming. Exploratory analyses show that sex significantly effects frequent video game play, platform and genre preference, and cognitive function. This study represents a novel exploration of the relationship between mobile video game play and cognition and adds support to the cognitive benefits of frequent video game play.</p>

Published: April 2024

<p>Malnutrition is correlated with poor cognition; however, an understanding of the association between nutrition risk, which precedes malnutrition, and cognition is lacking. This study aimed to determine if nutrition risk measured with the SCREEN-8 tool is associated with cognitive performance among cognitively healthy adults aged 55+, after adjusting for demographic and lifestyle covariates. Sex- and age-stratified analyses were also explored. Baseline data from the Canadian Longitudinal Study on Aging was used. Cognition was determined using a 6-measure composite score based on four executive functions and two memory tasks, taking into account age, sex, and education. Multivariable linear regression was performed while adjusting for body mass index (BMI), lifestyle, and health covariates in the entire sample (<em>n</em> = 11 378) and then stratified by sex and age. Approximately half of participants were female (54.5%) aged 65+ (54.1%). Greater nutrition risk was associated with poorer cognitive performance in the entire sample (<em>F</em>[1, 11 368] = 5.36, <em>p</em> = 0.021) and among participants aged 55–64 (<em>n</em> = 5227; <em>F</em>[1, 5217] = 5.45, <em>p</em> = 0.020). Sex differences in lifestyle and health factors associated with cognition were apparent, but nutrition risk was not associated with cognition in sex-stratified models. Based on this analysis, there may be an association between nutrition risk and cognitive performance in older adults. When screening for either cognitive impairment or nutrition risk, complementary assessments for these conditions is warranted, as early intervention may provide benefit.</p>
Music listening does not inoculate the stress response in young and older adults

Published: April 2024

<p>Although the acute stress response is adaptive for survival, frequent and intermittent activation of the acute stress response may have negative health consequences over time. As such, the development of effective low-cost and noninvasive stress reduction interventions is important. Music listening is shown to promote faster physiological recovery following acute stress. However, there is a paucity of research examining the potential inoculation effect of music on stress reactivity and potential modifiers that may influence this effect such as music selection. Hence, the current study examined the potential inoculation effect of music on acute stress reactivity, as measured by a comprehensive set of stress indices. It was hypothesized that listening to music prior to acute stress exposure would decrease stress reactivity compared with white noise (WN), and that self-selected music would serve as a stronger inoculator than researcher-selected music. Participants (<em>N</em> = 109) were randomly assigned to either researcher-selected music (<em>n</em> = 36), self-selected music (<em>n</em> = 38), or a WN group (<em>n</em> = 35) and listened to either music or WN prior to undergoing the Trier Social Stress Test, a standardized psychosocial stress protocol. Outcome indices of stress included skin conductance, heart rate, salivary cortisol, and self-report affect. Analyses failed to show a significant inoculation effect of music on the stress response. Exploratory analyses did not reveal differential sex or age effects in stress inoculation. This study contributes to the growing literature on the neuroscience of music and presents a new line of questions that require further investigation. </p>

<p> </p>
<p><strong>Introduction:</strong> Cardiovascular disease risk factors (CVRFs) contribute to the development of cognitive impairment and dementia.</p>
<p><strong>Methods:</strong> This study examined the associations between circulating CVRF biomarkers and cognition in 386 cognitively healthy older adults (mean age = 78 ± 4 years, 53% females) selected from the Quebec Longitudinal Study on Nutrition and Successful Aging (NuAge). Memory, executive function, and processing speed were assessed at baseline and 2-year follow-up. CVRF biomarkers included total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), triglycerides, glucose, insulin, high sensitivity C-reactive protein (hs-CRP), homocysteine, protein carbonyls, and cortisol. Linear mixed models were used to determine associations between individual CVRF biomarkers and cognition at both time points.</p>
<p><strong>Results:</strong> HDL-C was most consistently associated with cognition with higher values related to better performance across several domains. Overall, stronger and more consistent relationships between CVRF biomarkers and cognition were observed in females relative to males.</p>
<p><strong>Discussion:</strong> Findings suggest that increases in the majority of circulating CVRFs are not associated with worse cognition in cognitively healthy older adults.</p>

Published: April 2024

<p>Stress exposure over the lifespan is robustly associated with accelerated cognitive decline in later life. Brain-derived neurotrophic factor (BDNF) is shown to regulate activity of the hypothalamic-pituitary-adrenal axis. The objective of this study was to evaluate the association betweenthe <em>BDNF</em> polymorphism and indices of stress among adults aged 50+. Community-dwelling middle-aged and older adults provided a blood sample for <em>BDNF</em> genotyping. Participants also sampled their saliva 5 times/day for 3 consecutive days for the measurement of diurnal cortisol and underwent the Trier Social Stress Test (TSST) for the measurement of stress reactivity. Among 121 adults aged 50–67 years (78% female; 89% Caucasian), 74 participants were Val/Val carriers and 47 carried 1 copy of the Met allele. Repeated-measures analyses did not reveal an association between BDNF genotype and diurnal salivary cortisol (<em>p</em> = 0.63); however, analyses revealed that Met+ carriers displayed lower levels of cortisol secretion in response to the TSST compared with Val/Val carriers; <em>F</em>(4.43, 496.238) = 2.57, <em>p</em> = 0.032. This is the first study to evaluate the role of the <em>BDNF</em> polymorphism in stress physiology among older adults. Future studies are needed to evaluate the lifespan interconnections between <em>BDNF</em> and stress physiology.</p>

Altered declarative memory in introverted middle-aged adults carrying the BDNF val66met allele
Authors: De Beaumont Louis , Fiocco Alexandra , Quesnel Geneviève , Lupien Sonia , Poirier Judes 
Published: April 2024

<p>Background: The val66met polymorphism of the brain-derived neurotrophic factor gene (BDNFMet) is associated with impaired learning/memory function, affective dysregulation and maladaptive personality traits. Here, we examine the potential relationship between the BDNFMet allele, introversion and declarative memory in middle-age adults.</p>
<p>Methods: A total of 132 middle-aged healthy adults took part in this study that included taking a blood sample for genetic profiling, a short battery of neuropsychological tests and the NEO-Five Factor Inventory (NEO-FFI), widely used to assess the Big Five personality.</p>
<p>Results: Controlling for age, level of education and sex, a multiple analysis of covariance (MANCOVA) computing the effect of BDNF polymorphism on extraversion and declarative memory revealed a significant association (<em>D</em>1,128 = 4.79; <em>p</em> = 0.03; <em>η</em>p2 = 0.053). Using the Sobel Goodman Mediation Test, it was found that 25.61% of the relationship between genotype and declarative memory performance was mediated by introversion. Subsequent correlational analyses yielded a strong and significant correlation (<em>β</em> = 0.53; <em>p</em> < 0.001) between introversion and declarative memory specific to BDNFMet individuals.</p>
<p>Conclusion: this study highlights the pertinence of further investigating gene × personality × environment interactions to account for the significant variability that is observed in cognitive function in late life.</p>
