Perceived Social Support (PSS) and Physical Activity (PA) could have an important role in reducing psychological distress in women with problems in the menopausal period. The aim was to analyze the
associations between a) Self-Perceived Health (SPH), prevalence of selfreported depression and anxiety, and mental health and its subscales, through the Goldberg General Health Questionnaire (GHQ-12) with b)
the Physical Activity Level (PAL) and c) the PSS, through the Duke-UNC -11 functional social support questionnaire in Spanish women with problems in the menopausal period. This document uses data from
the Spanish National Health Survey of 2017, focusing on women between 40 and 69 years of age with problems in the menopausal period. Dependency relationships were found between the prevalence
of depression and PAL, anxiety and PAL, and SPH with PAL (p < 0.001). Weak inverse correlations were found between PAL and mental health, Coping Success, Self-confidence, and Stress (rho: − 0.214 to − 0.258; p
< 0.001). Also, weak and very weak significant inverse correlations were found between PAL and all items of the GHQ-12. Weak inverse correlations were found between PSS scores and mental health, Coping, and
Stress (r: −0.201 to − 0.304; p < 0.001). Likewise, weak and very weak inverse correlations, although statistically significant, were found between the PSS scores and the responses to the GHQ-12 items.
Very active women with higher PSS have less psychological distress,
Does economic policy uncertainty influence SME performance?
(Universidad de Extremadura, Servicio de Publicaciones, 2022) Orden Cruz, Carmen; Paule Vianez, Jessica; Sánchez Escobedo, María de la Cruz; Moutinho, Victor; Universidad Rey Juan Carlos; Universidad de Extremadura.

The COVID-19 crisis has increased uncertainty. In particular, the Economic Policy Uncertainty (EPU) has been exacerbated due to taking a wide range of measures very fast to mitigate the impact of the pandemic on businesses and families. This impact on Small and Medium Enterprises (SMEs) is of great interest for their importance to the economies.
Thus, this paper analyzes the impact of EPU on SMEs’ performance, taking a sample of 80,620 Spanish SMEs and using the Generalized Method of Moments (GMM) estimators. The results show that EPU promotes the SME’s performance and how SME managers can take advantage of an adverse scenario.
Total plasma fatty acid responses to maximal incremental exercise after caffeine ingestion

Aerobic exercise is associated with changes in plasma fatty acid profile, whereas caffeine is known to exert action on lipolysis. However, the majority of this previous work has studied fatty acids as a single entity and not on an individual fatty acid basis, despite their differing roles and functions. The aim of this study was to assess the effect of 5 mg/kg body mass caffeine on maximal exercise and total plasma fatty acids profile. In a crossover, double blinded, randomized placebo controlled trial involving 20 untrained men who were not customary caffeine consumers, performance and ventilatory responses during an incremental maximal aerobic exercise protocol, along with plasma total fatty acid profile (by gas chromatography), were assessed. Exercise time to exhaustion ( p < 0.01), maximum power output ( p < 0.05) and maximum oxygen consumption increased ( p < 0.05) significantly after caffeine ingestion. After exercise with caffeine, saturated fatty acids as a proportion of total fatty acids increased ( p < 0.05), while decreases in trans oleic acid ( p < 0.05), arachidic acid ( p < 0.05) and delta 9.2 desaturation index ( p < 0.05) were found. The ingestion of caffeine before maximal incremental exercise produces an ergogenic effect, with the combination of caffeine and improved exercise performance resulting in greater relative fat oxidation and post exercise differences in individual plasma free fatty acid proportions.
