Accelerated epigenetic aging has been associated with changes in cognition. However, due to the lack of neuroimaging epigenetics studies, it is still unclear whether accelerated epigenetic. Aging in young adulthood might underlie the relationship between altered brain dynamics and cognitive functioning. We conducted neuroimaging epigenetics follow-up of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC) prenatal birth cohort in young adulthood and tested the possible mediatory role of accelerated epigenetic aging in the relationship between dynamic functional connectivity (DFC) and worse cognition. A total of 240 young adults (51% men; 28-30 years, all of European ancestry) participated in the neuroimaging epigenetics follow-up. Buccal swabs were collected to assess DNA methylation and calculate epigenetic aging using Horvath's epigenetic clock. Full-scale IQ was assessed using the Wechsler adult intelligence scale (WAIS). Resting-state functional magnetic resonance imaging (rs-fMRI) was acquired using a 3T Siemens Prisma MRI scanner, and DFC was assessed using mixture factor analysis, revealing information about the coverage of different DFC states. In women (but not men), lower coverage of DFC state 4 and thus lower frequency of epochs with high connectivity within the default mode network and between default mode, fronto-parietal, and visual networks was associated with lower full-scale IQ (AdjR2 = 0.05, std. beta = 0.245, p = 0.008). This relationship was mediated by accelerated epigenetic aging (ab = 7.660, SE = 4.829, 95% CI [0.473, 19.264]). In women, accelerated epigenetic aging in young adulthood mediates the relationship between altered brain dynamics and cognitive functioning. Prevention of cognitive decline should target women already in young adulthood.

Numerous studies have now documented that athletes of different competition levels vary in their motivational styles. Some are internally motivated and train to be better based on intrinsic values, whereas others are controlled by external pressures that drive performance. A third style does not make causal attributions regarding their performance and are amotivated. In the current study, we used latent profile analysis to examine unique typologies of sports motivation in 456 Czech university students comprised of both recreational and more elite athletes participating in various sports and attending a sport education program. Four qualitatively distinct profiles were distinguished varying in the composition of intrinsic, extrinsic, and amotivation. The four profiles differed in their mean levels of social physique anxiety, global self-esteem, and physical self-worth, three markers of how a person feels about themselves in terms of normative standards. Multiple group comparisons based on gender, individual versus team sports, and level of competition reinforced relative consistency in profile composition. Results are discussed in terms of how people can blend different motivational styles, what this portends for self-beliefs, and whether there is relative consistency across meaningful groups.

Motivations for pornography use may vary across gender identities, sexual orientations, and geographical regions, warranting examination to promote individual and public health. The aims of this study were to validate the Pornography Use Motivations Scale (PUMS) in a diverse, multicultural sample, and develop a short form (PUMS-8) that can assess a wide range of pornography use motivations. Using data from 42 countries (N = 75,117; Mage = 32.07; SDage = 12.37), enabled us to thoroughly evaluate the dimensionality, validity, and reliability of the Pornography Use Motivations Scale (PUMS), leading to the development of the more concise PUMS-8 short scale. Additionally, language-, nationality-, gender-, and sexual-orientation-based measurement invariance tests were conducted to test the comparability across groups. Both the PUMS and the PUMS-8 assess eight pornography use motivations, and both demonstrated excellent psychometric properties. Sexual Pleasure emerged as the most frequent motivation for pornography use across countries, genders, and sexual orientations, while differences were observed concerning other motivations (e.g. self-exploration was more prevalent among gender-diverse individuals than men or women). The motivational background of pornography use showed high similarity in the examined countries. Both the PUMS and the PUMS-8 are reliable and valid measurement tools to assess different types of motivations for pornography use across countries, genders, and sexual orientations. Both scales are recommended for use in research and clinical settings.

In this manuscript, we highlight the evolutionary origins of mitochondria from bacterial endosymbionts and explore their contributions to health, energy metabolism, and neural-immune communication. Mitochondrial adaptability and the roles played by these organelles in promoting oxygen-dependent ATP production provide critical regulation of cognition, motivation, and inflammation. Hypoxia has been identified as an important initiator of inflammation, neurodegeneration, and mitochondrial dysfunction, emphasizing the overall importance of oxygen homeostasis to health and well-being. The Behavior, Exercise, Relaxation, and Nutrition framework highlights these observations as tools that can be used to optimize mitochondrial efficiency. Interestingly, mitochondrial dysfunction may also be linked to psychiatric disorders (e.g., schizophrenia), a hypothesis that focuses on energy dynamics, a proposal that may extend our understanding of these disorders beyond traditional neurotransmitter-focused concepts. Collectively, these perspectives underscore the critical contributions of mitochondria to health and disease and offer a novel framework that may help to explain the connections featured in mind-body medicine.

AIMS: To assess perceptions, motivations and barriers to treatment adherence depending on emotional, lifestyle, medical and non-adherence risk profiles in hypertensive patients. METHODS AND RESULTS: Cross-sectional data were obtained using an online anonymous survey. Four distinct global risk scores (medical, lifestyle, emotional and quality of life (QoL) and non-adherence risk scores) were calculated based on the responses to specific groups of questions. A total of 2615 treated hypertensive patients (≥18 years of age) from 5 European countries completed the questionnaire. Mean (SD) age was 69.6 years (5.8); 54% males. Overall, antihypertensive therapy represented a low burden in patients' daily life (2.9/10 in the Likert scale). Perfect self-reported adherence was claimed by 59.8% of participants. Reporting of non-adherence episodes to physicians was low (13% always/often). Participants with a high non-adherence risk score had a greater number of associated diseases (obesity, sleep disturbances, depression and cardiac complications), a higher treatment-associated burden on daily life, a greater stress level and more antihypertensive pills per day (p < 0.001 for all). No correlation was found between the clinical and lifestyle risk scores and the risk of non-adherence. The emotional score correlated significantly with the non-adherence risk score (p < 0.001). Comparing patients with a low/middle risk to those with a high risk of non-adherence, female gender and age >65 years were associated with a lower odd ratio of non-adherence whereas depression, stress, family hardships, negative information on drugs and poor information were associated with higher odds of non-adherence. CONCLUSIONS: This large survey reveals several underestimated issues regarding patients' perspective in hypertension. It highlights the impact of emotions, exposure to family hardships, and stress on the risk of non-adherence. Non-adherence is underreported by patients; hence it remains mostly unrecognised.

Maternal diet during pregnancy has been associated with brain development and cognitive function in offspring, but the mechanisms mediating these relationships remain poorly understood. We conducted a longitudinal neuroimaging follow-up of a prenatal birth cohort and used Food Frequency Questionnaires completed by the mother in mid-pregnancy to calculate prenatal Dietary Inflammatory Index (DII) and tested its relationship with brain gyrification, an index of early brain development, and IQ in young adults (n = 179, age 28-30). The longitudinal gyrification data were available for a subset of these individuals (n = 77, age 23-24). A higher maternal pro-inflammatory diet during pregnancy, as represented by higher DII, was associated with worse verbal IQ but not performance IQ in young adulthood. These findings were independent of sex and remained significant after adjusting for maternal education, maternal stressful life events during pregnancy, maternal smoking during pregnancy, prenatal supplements (e.g. folic acid, iron, zinc, calcium, vitamins), and maternal age at birth. Moreover, higher DII was associated with altered cortical gyrification in the early as well as the late 20, particularly in men. Gyrification of the anterior middle and inferior frontal gyrus mediated the relationship between prenatal DII and verbal IQ in young adulthood. These findings support the use of cortical gyrification as a proxy marker of early brain development and suggest it may underlie the relationship between maternal diet during pregnancy and its long-term impact on cognitive skills in offspring. They also have important implications for pregnant women who might be able to optimize the brain development and verbal IQ of their children through an anti-inflammatory diet.
