Dark Chocolate Intake Positively Modulates Redox Status and Markers of Muscular Damage in Elite Football Athletes: A Randomized Controlled Study

Intensive physical exercise may cause increase oxidative stress and muscular injury in elite football athletes. The aim of this study was to exploit the effect of cocoa polyphenols on oxidative stress and muscular injuries induced by intensive physical exercise in elite football players. Oxidant/antioxidant status and markers of muscle damage were evaluated in 24 elite football players and 15 controls. Furthermore, the 24 elite football players were randomly assigned to either a dark chocolate (>85% cocoa) intake (n = 12) or a control group (n = 12) for 30 days in a randomized controlled trial. Oxidative stress, antioxidant status, and muscle damage were assessed at baseline and after 30 days of chocolate intake. Compared to controls, elite football players showed lower antioxidant power and higher oxidative stress paralleled by an increase in muscle damage markers. After 30 days of dark chocolate intake, an increased antioxidant power was found in elite athletes assuming dark chocolate. Moreover, a significant reduction in muscle damage markers (CK and LDH, p < 0.001) was observed. In the control group, no changes were observed with the exception of an increase of sNox2-dp, H2O2, and myoglobin. A simple linear regression analysis showed that sNox2-dp was associated with a significant increase in muscle damage biomarker release (p = 0.001). An in vitro study also confirmed that polyphenol extracts significantly decreased oxidative stress in murine myoblast cell line C2C12-derived. These results indicate that polyphenol-rich nutrient supplementation by means of dark chocolate positively modulates redox status and reduced exercise-induced muscular injury biomarkers in elite football athletes. This trial is registered with NCT03288623

Psychological dimensions associated with youth engagement in climate change issues: a person-centered approach

Climate change is one of the greatest global threats that has ecological, economic, social, and psychological consequences. Nowadays, young people are the target of political agenda since they represent potential future policymakers. Consequently, it is crucial to identify the psychological features that contribute to engagement of young people in climate change issue. This study aimed at identifying and describing different configurations of youth perceiving and experiencing climate change. A sample of 224 participants (61% females; Mage = 21.04, SD = 1.65) were involved in study. From a cluster analysis emerged three distinct profiles, Eco-Disengaged, Eco-Engaged/Oriented and Eco-Engaged/Disoriented, which differ in levels of climate change awareness, worry and anxiety. Findings suggest that institutions might develop green education programs based on young people’s individual difference

Interplay between COVID-19, pollution, and weather features on changes in the incidence of acute coronary syndromes in early 2020

Coronavirus disease 2019 (COVID-19) has caused an unprecedented change in the apparent epidemiology of acute coronary syndromes (ACS). However, the interplay between this disease, changes in pollution, climate, and aversion to activation of emergency medical services represents a challenging conundrum. We aimed at appraising the impact of COVID-19, weather, and environment features on the occurrence of ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) in a large Italian region and metropolitan area

Microperimetric biofeedback in AMD patients

To analyse biofeedback training by microperimeter MP-1 (Nidek Technologies) on patients with Age Related Maculopathy (AMD). We enrolled 15 patients (10 female and 5 male) and examined total of 27 eyes with AMD. All the patient underwent 10 training sessions of 10 min for each eye, performed once a week using the MP-1 biofeedback examination. Statistical analysis was performed using Student's t-test. p values less than 0.05 were considered statistically significant. All patients displayed an improvement in visual acuity, fixation behaviour, retinal sensitivity an reading speed. The mean character size value improved from 36.4 to 11.7; this result was statistically significant (p = 0.031). A biofeedback examination using the MP-1 microperimeter can help the brain to memorize the final fixation location by increasing attention modulation, thereby providing an efficient preferred retinal locus for visual tasks in patients with macular disease and central scotoma. © 2007 Springer Science+Business Media, LLC

Maternal Parenting and Preschoolers&rsquo; Psychosocial Adjustment: A Longitudinal Study

Previous research reported that positive parenting and parenting stress might impact children&rsquo;s psychosocial adjustment. The current longitudinal study aimed at evaluating the associations over time between mothers&rsquo; positive parenting, their parenting stress, and their preschoolers&rsquo; social&ndash;emotional competence and emotional&ndash;behavioral difficulties. Participants were 53 Italian mothers, aged between 24 and 47 years (M = 35.30, SD = 5.28) at T0, and their children (females = 51%), aged between 3 and 6 years (M = 4.48, SD = 0.84) at T0. Mothers completed self-report scales at 2 time points (with a 2-year lag). An autoregressive cross-lagged model was tested that had a good fit to the data, &chi;2(6) = 3.37 ns, CFI = 1.00, RMSEA = 0.00. The results showed that maternal positive parenting at T0 negatively predicted maternal parenting stress at T1; maternal parenting stress at T0 negatively predicted children&rsquo;s social&ndash;emotional competence at T1. Moreover, at each time point, children&rsquo;s social&ndash;emotional competence was associated positively with maternal positive parenting and negatively with maternal parenting stress; children&rsquo;s emotional&ndash;behavioral difficulties were positively associated with maternal parenting stress. The results confirm that interactions with mothers are fundamental for children&rsquo;s psychosocial adjustment. Implications for research and practice aimed at reducing parenting stress and fostering positive parenting are discussed

Maternal Parenting and Preschoolers’ Psychosocial Adjustment: A Longitudinal Study

Previous research reported that positive parenting and parenting stress might impact children’s psychosocial adjustment. The current longitudinal study aimed at evaluating the associations over time between mothers’ positive parenting, their parenting stress, and their preschoolers’ social–emotional competence and emotional–behavioral difficulties. Participants were 53 Italian mothers, aged between 24 and 47 years (M = 35.30, SD = 5.28) at T0, and their children (females = 51%), aged between 3 and 6 years (M = 4.48, SD = 0.84) at T0. Mothers completed self-report scales at 2 time points (with a 2-year lag). An autoregressive cross-lagged model was tested that had a good fit to the data, 2(6) = 3.37 ns, CFI = 1.00, RMSEA = 0.00. The results showed that maternal positive parenting at T0 negatively predicted maternal parenting stress at T1; maternal parenting stress at T0 negatively predicted children’s social–emotional competence at T1. Moreover, at each time point, children’s social–emotional competence was associated positively with maternal positive parenting and negatively with maternal parenting stress; children’s emotional–behavioral difficulties were positively associated with maternal parenting stress. The results confirm that interactions with mothers are fundamental for children’s psychosocial adjustment. Implications for research and practice aimed at reducing parenting stress and fostering positive parenting are discussed

Standard Enucleation with Aluminium Oxide Implant (Bioceramic) Covered with Patient's Sclera

Purpose. We describe in our study a modified standard enucleation, using sclera harvested from the enucleated eye to cover the prosthesis in order to insert a large porous implant and to reduce postoperative complication rates in a phthisis globe. Methods. We perform initially a standard enucleation. The porous implant (Bioceramic) is then covered only partially by the patient's sclera. The implant is inserted in the posterior Tenon's space with the scleral covering looking at front. All patients were followed at least for twelve months (average followup 16 months). Results. We performed nineteen primary procedures (19 patients, 19 eyes, M; F) and secondary, to fill the orbital cavity in patients already operated by standard evisceration (7 patients, 7 eyes). There were no cases of implant extrusion. The orbital volume was well reintegrated. Conclusion. Our procedure was safe and effective. All patients had a good cosmetic result after final prosthetic fitting and we also achieved good prothesis mobility
