Induction of Extracellular Hydroxyl Radicals Production in the White-Rot Fungus Pleurotus eryngii for Dyes Degradation: An Advanced Bio-oxidation Process.

Among pollution remediation technologies, advanced oxidation processes (AOPs) are genuinely efficient since they are based on the production of strong, non-selective oxidants, mainly hydroxyl radicals (·OH), by a set of physicochemical methods. The biological counterparts of AOPs, which may be referred to as advanced bio-oxidation processes (ABOPs), have begun to be investigated since the mechanisms of induction of ·OH production in fungi are known. To contribute to the development of ABOPs, advanced oxidation of a wide number of dyes by the white-rot fungus Pleurotus eryngii, via a quinone redox cycling (QRC) process based on Fenton's reagent formation, has been described for the first time. The fungus was incubated with 2,6-dimethoxy-1,4-benzoquinone (DBQ) and Fe3+-oxalate, with and without Mn2+, leading to different ·OH production rates, around twice higher with Mn2+. Thanks to this process, the degradative capacity of the fungus increased, not only oxidising dyes it was not otherwise able to, but also increasing the decolorization rate of 20 dyes by more than 7 times in Mn2+ incubations. In terms of process efficacy, it is noteworthy that with Mn2+ the degradation of the dyes reached values of 90-100% in 2-4 h, which are like those described in some AOPs based on the Fenton reaction.

Perception of Parental Attitudes and Self-Efficacy in Refusing Alcohol Drinking and Smoking by Spanish Adolescents: A Cross-Sectional Study.

Adolescents are particularly vulnerable to initiation of the use of substances harmful to health, and its increase is cause for concern. The objective of this study was to analyze the relationship between self-efficacy in refusing alcohol and the attitude of adolescents toward drugs and their perception of their parents' attitude toward refusal. The study was carried out in 2019 in a sample of 1287 students from 11 public high schools in the province of Almería (Spain). Students were aged 14 to 18 in their 3rd and 4th year of compulsory secondary education. The Drinking Refusal Self-Efficacy Questionnaire-Revised Adolescent version (DRSEQ-RA), Attitudes Toward Taking Drugs-Basic BIP Scale and the Parents' attitudes Toward Drug Use were administered. The results showed that family relationships seem to have a direct impact on adolescent patterns in smoking and drinking alcohol. However, a favorable attitude toward drugs is a risk factor for drinking alcohol and smoking tobacco. The self-efficacy dimension also acts as a protective factor against the probability of using alcohol or tobacco. The conclusions emphasized that communication within the family core can increase or decrease the risk of adolescents using substances harmful to health.

Repercussions of perceived threat to health in the Spanish population.

Studies have shown that COVID-19 has had a worldwide psychological impact. Confinement due to COVID-19 has had important repercussions on the mental health of the general population, with high levels of stress, anxiety, depressive symptoms, post-traumatic stress disorder, and so forth. Similarly, important labor, economic and social changes taking place are affecting people's well-being. The objective of this study was to analyze the repercussions of perceived threat from COVID-19 on the mental health of the population, and to evaluate the mediating role of perceived economic impact. The participants were 1160 adult residents of Spain aged 18 to 82, 69.9% of whom were women. A sociodemographic questionnaire, the Questionnaire on Perception of Threat from COVID-19 and the General Health Questionnaire were administered. Perceived threat had a positive direct effect on all four health dimensions analyzed. Among the indirect effects, the perceived economic impact of COVID-19 mediated in the relationship between perceived threat and each of the health dimensions. The results of this study have demonstrated the need to promote joint action promoting public mental health to minimize the psychological repercussions of new outbreaks.

The "Mask Effect" of the Emotional Factor in Nurses' Adaptability to Change: Mental Health in a COVID-19 Setting.

During healthcare catastrophes, such as the current COVID-19 pandemic, nurses are exposed to highly stressful situations derived from their work and personal activity. Development of coping strategies for such situations can improve nurses' physical and mental health. This study analyzed nurses' adaptability to change, with attention to socio-demographic variables in a COVID-19 setting, and identified the repercussions on their health. This quantitative, observational and cross-sectional study had a sample of 351 nurses aged 22 to 64 with a mean age of 40.91 (SD = 10.98). The instruments used for the study were the ADAPTA-10 questionnaire and the General Health Questionnaire (GHQ-28). It was observed that age, sex, and having a stable partner significantly influenced scores on the emotional, cognitive-behavioral, and adaptation to change factors. Finally, the emotional factor mediated between positive COVID-19 in someone close and the presence of health problems. Understanding the elements that help adapt better to change and adversity enable effective interventions to be developed for improving emotional health of nurses, especially for those in whom there are positive cases of COVID-19 in their personal or work environment.

The predictive factors of mortality included being a male with various comorbidities, SARS-CoV-2 pneumonia, bacteremia and superinfections from A. baumannii.ConclusionThe outbreak of A. baumannii was a determining factor in the increases of the incidence of infection and the morbi-mortality of ICU patients.

Mental Health in Settings with COVID-19 Positive Cases in the Spanish Population: The Protective Role of the Capacity to Adapt to Change.

BACKGROUND: The capacity to adapt to change in complex, highly demanding situations, such as those derived from the COVID-19 pandemic, is essential in maintaining one's mental health. This study analyzed the mental health of the Spanish population in settings with COVID-19 positive cases and the protective role of adaptation to change. METHODS: The sample consisted of 1160 adult Spaniards aged 18 to 82 with a mean age of 38.29 (SD = 13.71). Data were collected by a CAWI (Computer Aided Web Interviewing) survey which included the General Health Questionnaire (GHQ-28), Adaptation to Change Questionnaire (ADAPTA-10), and an ad hoc questionnaire related to COVID-19 (perceived economic impact, COVID-19 positive diagnosis or not, and whether there was a positive case close to them). RESULTS: The data revealed that the perceived economic impact showed a negative association between the emotional factor and the total score in adaptation to change. Lastly, the emotional factor in adaptation to change operated as a protector from the effect that a setting with COVID-19 positive cases exerts on mental health. CONCLUSIONS: Coping with COVID-19 requires strengthening the capacity for adaptation to changes generated in the setting, especially emotional, as it could contribute to improving the mental health of individuals, especially in those settings where they find and know a COVID-19 positive case.

Whole-genome analyses reveal a novel prophage and cgSNPs-derived sublineages of Brachyspira hyodysenteriae ST196.

BACKGROUND: Brachyspira (B.) hyodysenteriae is a fastidious anaerobe spirochete that can cause swine dysentery, a severe mucohaemorragic colitis that affects pig production and animal welfare worldwide. In Switzerland, the population of B. hyodysenteriae is characterized by the predominance of macrolide-lincosamide-resistant B. hyodysenteriae isolates of sequence type (ST) ST196, prompting us to obtain deeper insights into the genomic structure and variability of ST196 using pangenome and whole genome variant analyses. RESULTS: The draft genome of 14 B. hyodysenteriae isolates of ST196, sampled during a 7-year period from geographically distant pig herds, was obtained by whole-genome sequencing (WGS) and compared to the complete genome of the B. hyodysenteriae isolate Bh743-7 of ST196 used as reference. Variability results revealed the existence of 30 to 52 single nucleotide polymorphisms (SNPs), resulting in eight sublineages of ST196. The pangenome analysis led to the identification of a novel prophage, pphBhCH20, of the Siphoviridae family in a single isolate of ST196, which suggests that horizontal gene transfer events may drive changes in genomic structure. CONCLUSIONS: This study contributes to the catalogue of publicly available genomes and provides relevant bioinformatic tools and information for further comparative genomic analyses for B. hyodysenteriae. It reveals that Swiss B. hyodysenteriae isolates of the same ST may have evolved independently over time by point mutations and acquisition of larger genetic elements. In line with this, the third type of mobile genetic element described so far in B. hyodysenteriae, the novel prophage pphBhCH20, has been identified in a single isolate of B. hyodysenteriae of ST196.

Anxiolytic and Antidepressant Use and Burnout: Optimism as a Mediator in Spanish Nurses.

The aim of this study was to analyze the relationship between burnout, the use of drugs (anxiolytics and antidepressants) and optimism in nurses. At the end of 2018, a cross-sectional descriptive study was carried out with a sample of actively employed nurses recruited by snowball sampling. The sample consisted of 1432 nurses in Andalusia (Spain), aged 22-58, who were working at the time of data collection, 83.2% of whom were women. Data were collected anonymously in an ad hoc questionnaire about sociodemographic information and use of anxiolytics and/or antidepressives: the Brief Burnout Questionnaire-Revised for Nurses (CBB-R) and the Life Orientation Test-Revised (LOT-R). Descriptive, mediation and moderation analyses were performed, with significant results having a p-value less than 0.05. The results on burnout showed significant relationships with use of the drugs. In particular, personal impact, job dissatisfaction and motivational abandonment were positively related to use of certain of the anxiolytics and antidepressants presented, while the correlation with the social climate was negative. Furthermore, optimism correlated negatively with drug use. Knowing that optimism can alleviate the repercussions of the use of drugs opens up new lines of research and the possibility of developing programs aimed at promoting a positive disposition in the face of complicated events.

Adaptation to Change Questionnaire for Nurses: Validation and New Needs in the Context of COVID-19.

BACKGROUND: The worldwide pandemic caused by the SARS-CoV-2 coronavirus has challenged healthcare systems and the professionals who work in them. This challenge involves strong changes to which nurses have had to quickly adapt. Emotional and cognitive-behavioral factors influence the capacity for adaptation to change. Based on this model, the objective of this study was to validate the Adaptation to Change Questionnaire (ADAPTA-10) for identifying professionals in a population of nurses who have problems adapting to adverse situations such as those caused by COVID-19. METHODS: This study was performed with a sample of 351 nurses. (3) Results: The ADAPTA-10 questionnaire was found to have good psychometric properties, and to be an effective, useful tool for nurses in research and clinical practice. The two-dimensional structure proposed in the original model was confirmed. Scales are also provided by sex for evaluation of adaptation to change; the highest scores on the emotional component were among nurses who had not personally encountered the virus. CONCLUSIONS: This instrument will be able to detect of the needs for adaptation to the new reality associated with COVID-19, as well as other situations in which nurses are immersed that demand adaptation strategies.

Emotional Intelligence Profiles and Mobbing in Nursing: The Mediating Role of Social Support and Sensitivity to Anxiety.

The prevalence of mobbing among nurses in various countries is around 17-20%. Some researchers have attempted to explain the success or failure of adaptation to the work environment and teamwork and to buffer the effects of psychological harassment in the workplace by incorporating emotional intelligence into the mobbing context. As its main objectives, this quantitative, observational, cross-sectional study analyzed the relationship between emotional intelligence and mobbing as perceived by nurses and sought to establish the mediating roles of other variables involved, such as social support and sensitivity to anxiety. The final sample consisted of 1357 Spanish, self-selected nurses aged 22-58 from multiple healthcare institutions. The questionnaires (Perceived Psychological Harassment Questionnaire, The Brief Emotional Intelligence Inventory, Brief Perceived Social Support Questionnaire, Anxiety Sensitivity Index-3) were implemented on a web platform, which enabled the participants to complete them online. Descriptive analyses and mediation models were estimated. Personal characteristics related to high sensitivity to anxiety and low emotional intelligence implied greater presence of mobbing at work. This mobbing may be buffered if the person perceives enough support from family, friends or significant others. Our results recommend reinforcing the social support network of nursing personnel to improve the work climate and training them in emotional intelligence in university and on-the-job programs.

Role of Personality and Positive and Negative Affects in Coping Strategies of Nurses: A Cross-Sectional Study.

Nurses are exposed to many highly stressful events. Individual variables, such as personality and affective state, have been related to vulnerability to maladaptive coping. Therefore, the objectives of this study were to analyze the relationships between the personality, positive and negative affects, and coping strategies of nurses and to establish the mediating role of affective state in the relationship between personality and coping. The sample was made up of 1,268 Spanish nurses aged 22-63 years who completed the Coping Strategies Inventory, the Positive and Negative Affect Schedule, and the 10-item Big Five Inventory. Descriptive analyses, correlations, and mediation models were estimated. The results showed relationships between the Big Five personality factors, positive and negative affects, and coping strategies. Negative affect was confirmed as a mediator between personality and less adaptive strategies and positive affect was confirmed on positive strategies. This study emphasizes the need to develop actions directed at teaching nurses adequate problem-solving strategies and training them in the ability to assign a different emotional value to complex situations.

Interpersonal Support, Emotional Intelligence and Family Function in Adolescence.

BACKGROUND: During adolescence, although the peer group exerts a strong influence on how the individual thinks and feels and on personal social values, the family still exerts a sustaining and supporting role. This study analyzed the relationships established between family function, emotional intelligence and perceived interpersonal support in adolescence. METHOD: The sample was made up of 1287 high school students aged 14 to 18 (M = 15.11; SD = 0.91) in the province of Almeria (Spain). RESULTS: The results showed moderate correlations between the intrapersonal emotional intelligence dimension and perceived availability of support (advice or orientation), and between the mood dimension of emotional intelligence and the three interpersonal support dimensions (appraisal, belonging and tangible). In addition, significant positive correlations were found between family function and the intrapersonal and mood dimensions of emotional intelligence, with medium and large effect sizes, respectively. Apart from that, the data revealed that students who could count on a more functional family referred to high empathy and acceptance by others and greater support in material or financial matters, followed by those with moderate family function. In addition, students from homes with severely dysfunctional families perceived less available support. Finally, students who said they could count on strong family function also scored higher on the intrapersonal factor of emotional intelligence. CONCLUSIONS: The implications of these findings for the development of emotional intelligence in early adolescence are discussed from the family context, considering the relationship between emotional intelligence and social support.

Emotional intelligence as a mediator in the relationship between academic performance and burnout in high school students.

Low performance of high school students and repeating a year are major problems in the education system. Low performance in the classroom generates negative emotions in young people and has been related to development of school burnout. The objective of this study was to analyze the repercussions of academic performance on burnout in high school students, and establish the role of emotional intelligence in this relationship. The sample was made up of 1287 high school students aged 14 to 18, who filled out questionnaires for evaluation of these variables. The results showed that youths who had failed a subject or had repeated a year showed more exhaustion and cynicism than their classmates with better performance and higher academic efficacy. A relationship was also found between school burnout and emotional intelligence in these adolescents, positive for self-efficacy and negative for cynicism and exhaustion. The model results showed that low academic performance affected burnout level, and that stress management and mood in emotional intelligence acted as a mediator in this relationship. In conclusion, development of emotional intelligence programs in the educational context is proposed as a measure for preventing burnout in the face of adverse high school academic events, such as failing or repeating a year.

The Complex Nature of School Violence: Attitudes Toward Aggression, Empathy and Involvement Profiles in Violence.

BACKGROUND: Aggressive behavior in adolescents has become a concern in education, where adapting to and going through high school may generate important behavior problems in adolescents. PURPOSE: Analyze the relationships between parental and adolescent attitudes toward aggression and empathy. Identify profiles of direct and indirect involvement in school violence and determine differences between groups with respect to the components of empathy and attitudes toward aggression. METHODS: The sample was comprised of 1287 high school students who were administered the Beliefs about Aggression and Alternatives questionnaire, the Parental Support for Fighting and the Interpersonal Reactivity Index. RESULTS: The results show that beliefs in favor of the use of aggression in adolescents correlate positively with the perception of strong support from parents for aggression in response to conflict. Similarly, higher levels of support for the use of nonviolent strategies are positively related to the perception of strong support from parents. The relationships established with the components of empathy analyzed, both cognitive and emotional, were negatively correlated with favorable attitudes toward aggression. Results concerning the groups directly involved indicated that there were significant differences in the components of empathy between the groups. Furthermore, the multivariate analysis applied to the direct involvement groups showed significant differences between the groups in taking perspective. Between-group differences in empathic concern were also statistically significant for the group of active observers. CONCLUSION: Taking perspective and empathic concern are moderating variables both for observers and victims and their parents in situations of violence.

Student burnout and engagement: Relationship with adolescent use of alcohol and attitudes towards authority / Agotamiento y compromiso de los estudiantes: Relación con el consumo de alcohol en adolescentes y actitudes hacia la autoridad

The burnout syndrome has been related to development of transgressive attitudes toward norms that facilitate risk behaviors in youth, such as drinking alcohol. On the contrary, academic engagement is related to positive attitudes toward authority which can slow down its use. The objective was analyze the relationships between burnout and academic engagement, attitudes toward authority and use of alcohol. Method: The sample included a total of 1,287 high school students who anonymously filled out the Maslach Burnout Inventory-Student Survey, the Utrecht Work Engagement Scale for Students and the Scale of Attitudes toward Institutional Authority in adolescents, along with questions on drinking alcohol. Results: It was observed that cynicism had a significant effect on positive attitude toward rule-breaking, and this in turn, on frequency of drinking. The engagement dedication factor was shown to have a significant direct effect on positive attitude toward institutional authority, and this on drinking frequency. Conclusions: Promoting measures for decreasing burnout in youth and stimulating academic engagement could have repercussions on attitudes toward rules and the presence of risk behavior. (AU)

Empathy, Affect and Personality as Predictors of Engagement in Nursing Professionals.

BACKGROUND: It seems that personality traits affect engagement and the quality of professional life, which is mediated by the emotional and affective states of nursing personnel. Therefore, the objectives of this study were to analyze the relationships between the components of empathy, affect, personality, and engagement, find personality profiles, identify the variables with the most explanatory value, and analyze the mediating role of the variables susceptible to intervention in the relationship between personality and the components of engagement. METHODS: A sample of 1268 nurses completed the Utrecht Work Engagement Scale, 10-item Big Five Inventory, Basic Empathy Scale, and Positive and Negative Affect Schedule. RESULTS: Empathy, affect, and personality influence engagement factors in nurses. The vigor and absorption factors of engagement showed a positive relationship with empathy, positive affect, and all of the Big Five personality factors except neuroticism with which the relationship was negative. Personality affected the vigor, dedication, and absorption factors of engagement, and cognitive empathy mediated this relationship. CONCLUSIONS: This study shows the need to continue investigating the factors that affect and mediate in engagement of nursing professionals.

Study of Cyberbullying among Adolescents in Recent Years: A Bibliometric Analysis.

In recent years, cyberbullying has been recognized as a severe public health problem and is drawing growing interest. The objective of this study was to perform a bibliometric analysis of the scientific production on adolescent cyberbullying in the last decade. A search for publications was made in the Web of Science database, where the 1530 documents identified were analyzed with BibExcel software and visualized using the Pajek and VOSviewer tools. The predominant language in the publications was English, followed by Spanish. The publication rate was shown to have increased in recent years. The journal "Computers in Human Behavior" had the highest production. The repercussion of new technologies on this phenomenon has been felt, and research groups have enlarged their production in response to the problem. A systematic review and/or meta-analysis examining the contents of the studies identified and the variables related to this problem is therefore necessary. This could identify a point of reference for research in this field and a basis for future reviews of its development and progress over time.

Emotional Intelligence and Academic Engagement in Adolescents: The Mediating Role of Self-Esteem.

BACKGROUND: Academic engagement is a variable of vital importance in adolescence due to its relationship with academic adjustment and its protective role against risk behaviors. Therefore, the objective of this study was to find out the variables involved in its development. OBJECTIVE: The specific objectives were to analyze the relationship between emotional intelligence, self-esteem and academic engagement, and determine the mediating role of self-esteem in the relationship between emotional intelligence and engagement in adolescence. METHODS: The sample of 1287 high school students used for this filled in the Utrecht Work Engagement Scale Student, Brief Emotional Intelligence Inventory and the Rosenberg Self Esteem Scale. RESULTS: The results showed the existence of positive relationships between vigor, dedication and absorption with the emotional intelligence factors and self-esteem. Furthermore, the mediation models showed the direct effect of emotional intelligence on engagement of youths. Self-esteem acted as a mediator in the relationship between intrapersonal factors, stress management and adaptability of emotional intelligence and engagement. CONCLUSION: Design of emotional intelligence intervention programs are recommended as a measure for promoting self-esteem and engagement in adolescence.
