Introduction: Previous research has shown that personality traits and gaming motives are important predictors for explaining regular and disordered gaming. However, the mediating role of gaming motives in the relation between personality traits and video game outcomes (e.g., time spent gaming or disordered gaming) has been scarcely studied and limited cross-national studies have addressed this issue. The present study aimed to examine the direct and indirect effects of the Big Five personality traits on weekly gaming and disordered gaming via gaming motives across seven countries., Method: 3540 college student gamers (59.5% women) from the U.S., Canada, Spain, Argentina, Uruguay, South Africa and England completed the online survey. Structural equation modeling was conducted to test models. Multigroup models were employed to test model invariance across countries., Results: Significant, albeit weak, relations were found between personality traits and gaming outcomes, and were mediated mostly by coping motives in predicting disordered gaming, and by social interaction and recreation (to a lesser extent) motives in predicting weekly gaming. Some minor, yet significant, differences across countries appeared and are discussed in detail., Discussion: The present findings indicate that the differential interrelations between personality traits, gaming motives, and video gaming outcomes may be generalized in college students across countries., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Senecio nutans Sch. Bip., S. viridis var. viridis Phill. and S. spegazzinii Cabrera are native species used in traditional medicine of northwestern Argentina. The total phenolics, flavonoids and caffeoylquinic acids contents, as well as radical scavenging, antioxidant, hemolytic and cytotoxic activities of aqueous extracts (infusion and decoction) of all three species were determined. S. nutans was the most active. The extracts did not show antibacterial activity. Alkaloids were not detected in any of the aqueous extracts of the three studied species.

Chronic obstructive pulmonary disease (COPD) has increased its prevalence in females. Women have been described as more symptomatic. There are few studies considering gender differences in COPD. The aim of our study was to determine the influence of gender on quality of life, symptoms, treatment, risk factors and cardiovascular disease in a population of patients with COPD. In this prospective observational cross-sectional study, the included COPD patients were consecutively admitted between September 1, 2008 to March 1, 2010. We registered age, sex, smoking history, risk factors and cardiovascular disease, treatment and severity of COPD. We measured ankle-brachial index (ABI) and performed EuroQol-5D. Two hundred forty six patients were included (195 men). There were more former smokers among men (68.7% vs. 15.7%, p < 0.001), men had a lower FEV1 (48.7% ± 15.7 vs. 58.2% ± 10.9 of theoretical, p < 0.001) and higher frequency of ischemic heart disease (16.4% vs. 5.9%, p = 0.04). Women showed a higher prevalence of COPD without exposure to smoke cigarette (64.7% vs. 7.2%, p < 0.001), more symptoms of anxiety and depression (p = 0.004) and less frequently altered ABI (20% vs. 41. 6%, p = 0.01).There were differences in COPD with respect to sex with more severe pulmonary and cardiovascular disease in men and more symptoms of anxiety and depression in women.
