    Daycare center attendance buffers the effects of maternal authoritarian parenting style on physical aggression in children

    Get PDF
    A maternal authoritarian style has been related to the development of physical aggression during childhood and later future social problems; however, not too many studies have detected other than individual or family factors that may buffer this maternal effect. This work examines whether daycare center attendance may moderate the relationships between a mother authoritarian style and physical aggression. The study sample was 72 (40 girls) kindergarten children from Spain. Parents were asked to complete two questionnaires focused on individual family characteristics and parenting styles. At age 5, children physical aggression was assessed by direct observation at playtime; aggression scores at 6 was obtained by a peer-rated questionnaire. A least squared multiple regression was performed after controlling for children’s level of physical aggression at 5, child sex and siblings. A positive contribution of maternal authoritarian style on physical aggression was detected. Daycare center attendance appears to attenuate the effect of the mother’s authoritarian style on physical aggression, only in boys.This study was funded by the Andalusian Regional Government’s Plan Andaluz de Investigación (PAI-2003/04, HUM-554) and by the Basque Country Government (GIC07/19-IT-238-07)

    Invasive mold infection (IMI) remains a major cause of mortality in high-risk hematological patients. The aim of this multicenter retrospective, observational study was to evaluate antifungal combination therapy (ACT) for proven and probable IMI in hematological patients. We analyzed 61 consecutive cases of proven (n=25) and probable (n=36) IMI treated with ACT collected from eight Spanish hospitals from January 2005 to December 2009. Causal pathogens were: Aspergillus spp (n=49), Zygomycetes (n=6), Fusarium spp (n=3), and Scedosporium spp (n=3). Patients were classified in three groups according to the antifungal combination employed: Group A, liposomal amphotericin B (L-AmB) plus caspofungin (n=20); Group B, LAmB plus a triazole (n=20), and Group C, voriconazole plus a candin (n=21). ACT was well tolerated with minimal adverse effects. Thirty-eight patients (62%) achieved a favorable response (35 complete). End of treatment and 12-week survival rates were 62% and 57% respectively, without statistical differences among groups. Granulocyte recovery was significantly related to favorable response and survival (p<0.001) in multivariate analysis. Our results suggest that comparable outcomes can be achieved with ACT in high risk hematological patients with proven or probable IMI, whatever the combination of antifungal agents used

    The aim of this piece of research was to study the existence of clusters based on anger, empathy and cortisol and testosterone measures associated with aggressive behavior in school-aged children. The sample group comprised 139 eight-year-old children (80 boys and 59 girls). Aggressive behavior was measured using the Direct and Indirect Aggression Scale. Both psychological and biological variables were used to determine psychobiological profiles. The psychological variables considered were trait anger, measured using the State-Trait Anger Expression Inventory for Children and Adolescents, and empathy, measured using the Empathy Quotient-Child Version. Testosterone and cortisol concentrations were measured through saliva samples and analyzed using an ELISA (Enzyme-linked immunosorbent assay). A Cluster Analysis revealed three clusters which were clearly different as regards their psychological and biological characteristics. The analysis of variance (ANOVA) revealed that the cluster characterized by having higher anger levels, lower empathy levels and higher testosterone and cortisol levels was more aggressive than the other two (p < .0001, η2 = .19). The results indicate that studying psychological and biological variables together may help establish differentiated aggression patterns among children

    Objectives: Previous studies have shown that dietary components such as oleic acid or polyphenols exert beneficial effects on endothelium. We aimed to assess the impact of regular consumption of Iberian cured-ham (ICH) on endothelial function. Design: An open-label, randomized controlled parallel study. Setting: Volunteers recruited through advertisements at a hospital in Madrid, Spain. Participants: 102 Caucasian adults (76.8% females) aged 25-55 years, and free from cardiometabolic disease. Intervention: Participants were randomized to an ICH-enriched ad libitum diet or an ad libitum diet without ICH for 6 weeks. Subjects in ICH group were randomly provided with either acorn- or mixed-fed ICH, and followed up for an additional 6-week period under their usual diet. Measurements: Clinical parameters, biomarkers of endothelial function and oxidative stress, microvascular vasodilatory response to hyperemia and arterial stiffness were measured before and after the intervention. Results: After 6 weeks, a larger decrease in PAI-1 was observed in subjects consuming ICH compared to the Control group (-6.2±17.7 vs. 0.3±1.4 ng/ml; p=0.020). Similarly, microvascular vasodilatory response to hyperemia showed a significant increase (112.4±391.7 vs. -56.0±327.9%; p=0.007). However, neither oxidative stress, hemodynamic nor clinical parameters differed significantly over the study. Additionally, after stopping ICH consumption, improvements in PAI-1 remained for 6 additional weeks with respect to baseline (p=0.006). Conclusion: The present study demonstrates, for the first time, that regular consumption of ICH improves endothelial function in healthy adults. Strategies aimed to preserve or improve the endothelial function may have implications in vascular aging beyond the prevention of the atherothrombotic disease

    Knowing the past to improve the future: Estimating historical fishing catches to improve fisheries management in the Western Mediterranean Sea

    We developed for the first time the commercial fishing catches reconstruction of the Balearic Islands (Western Mediterranean) between 1950 and 2010, by adding non-reported components, including unreported landings and discards, to the official reported landing data. To back‑estimate historical unreported landings and discards, collaboration and information acquired from fishermen were essential, as gathered through interviews and observer programs of the Spanish Oceanographic Institute (IEO) on board commercial bottom trawling fleet. We estimated a total catch of 511,500 t over the period 1950‑2010, of which official landings represented 49% (around 248,000 t), followed by unreported catches (32%) and discards (20%). A decrease in unreported catches was observed during the period 1950-2010 (from 58% to 38%) due to a reduction of unreported landings, but substantial efforts are still required to improve the recordings of actual fishing catches. This work contributes to the global assessment of fisheries removals led by the Sea Around Us and aims to provide the basis for an improved management of the Balearic Islands and Mediterranean Sea fisheries

    En hipocótilos de plántulas de girasol sensibles y resistentes a la infección por el hongo parásito Plasmopara halstedii, responsable del mildiu, los análisis mediante quimioluminiscencia de ozono revelaron una mayor producción de óxido nítrico en la variedad sensible frente a la resistente, tanto en plantas controles como en plantas inoculadas.La inmunolocalización mediante microscopía de fluorescencia y microscopía confocal láser mostró la localización extensiva de NOS (Óxido nítrico sintasa) y Snitrosoglutation (GSNO) en células parenquimáticas. La lozalización tisular preferente del GSNO en la zona de entrada del patógeno en el hipocótilo, evidencia la posible participación del óxido nítrico en los mecanismos de defensa celulares de respuesta inmediata frente a la invasión por patógenos y antes de la inducción de la producción de óxido nítrico por las proteínas responsables de su generación.El análisis de estos resultados evidencia la presencia en células de hipocótilos de girasol de proteínas tipo NOS y sugiere la participación de la NOS, del óxido nítrico (NO·) y del GSNO en la respuesta de la planta frente al estrés biótico por el hongo Plasmopara halstedii

    Measuring for change : A multi-centre pre-post trial of an air quality feedback intervention to promote smoke-free homes

    Second-hand smoke exposure in the home is a serious cause of ill-health for children. Behaviour change interventions have been developed to encourage parents to keep homes smoke-free. This study evaluates a novel air quality feedback intervention using remote air quality monitoring with SMS and email messaging to promote smoke-free homes among families from deprived areas. This paper presents a pre-post study of this intervention. Using internet connected monitors developed with the Dylos DC1700, daily SMS and weekly email feedback provided for 16 days to participants recruited in four European countries. Participants were recruited based on their stage of change, in order to target those most able to achieve smoke-free homes. The primary outcome measure was median change in mean fine particulate matter (PM) concentration between baseline and follow-up periods, while secondary outcome measures included change in time over the World Health Organisation (WHO) guideline limit for PM exposure over 24 h (25 µg/m) in those periods and the number of homes where PM concentrations reduced. Telephone interviews were conducted with participants in Scotland post-intervention to explore intervention experience and perceived effectiveness. Of 86 homes that completed the intervention study, 57 (66%) experienced pre-post reductions in measured PM. The median reduction experienced was 4.1 µg/m (a reduction of 19% from baseline, p = 0.008). Eight homes where concentrations were higher than the WHO guideline limit at baseline fell below that level at follow-up. In follow-up interviews, participants expressed positive views on the usefulness of air quality feedback. Household air quality monitoring with SMS and email feedback can lead to behaviour change and consequent reductions in SHS in homes, but within the context of our study few homes became totally smoke-free

    Borrelia burgdorferi infection induces long-term memory-like responses in macrophages with tissue-wide consequences in the heart

    Lyme carditis is an extracutaneous manifestation of Lyme disease characterized by episodes of atrioventricular block of varying degrees and additional, less reported cardiomyopathies. The molecular changes associated with the response to Borrelia burgdorferi over the course of infection are poorly understood. Here, we identify broad transcriptomic and proteomic changes in the heart during infection that reveal a profound down-regulation of mitochondrial components. We also describe the long-term functional modulation of macrophages exposed to live bacteria, characterized by an augmented glycolytic output, increased spirochetal binding and internalization, and reduced inflammatory responses. In vitro, glycolysis inhibition reduces the production of tumor necrosis factor (TNF) by memory macrophages, whereas in vivo, it produces the reversion of the memory phenotype, the recovery of tissue mitochondrial components, and decreased inflammation and spirochetal burdens. These results show that B. burgdorferi induces long-term, memory-like responses in macrophages with tissue-wide consequences that are amenable to be manipulated in vivo.Supported by grants from the Spanish Ministry of Science, Innovation and Universities (MCIU) co-financed with FEDER funds (SAF2015-65327-R and RTI2018-096494-B-100 to JA; BFU2016-76872-R to EB, AGL2017-86757-R to LA, SAF2017-87301-R to MLMC, SAF2015-64111-R to AP, SAF2015-73549-JIN to HR), Instituto de Salud Carlos III (PIE13/0004 to AP), the Basque Government Department of Health (2015111117 to LA), the Basque Foundation for Innovation and Health Research (BIOEF), through the EiTB Maratoia grant BIO15/CA/016/BS to MLMC, the regional Government of Andalusia co-funded by CEC and FEDER funds (Proyectos de Excelencia P12-CTS-2232) and Fundación Domingo Martínez (to AP).
