Competitive Psychological Disposition and Perception of Performance in Young Female Soccer Players

The athletes’ psychological disposition is a factor that is increasingly considered by researchers as a key to sports performance, even as a mediator between the physical, technical and tactical abilities of the athlete and their competitive performance, thus acquiring great relevance in training and in sports performance. The purpose of this study is to analyze the psychological characteristics of young soccer players and their relation to their performance perception, made both by the player herself and by their coaches. The sample is composed of 108 women (M age = 15.53, SD age = 1.05), with ages between 13 and 17 years (13 years, n = 1, 14 years, n = 18, 15 years, n = 36, 16 years, n = 29, 17 years, n = 24), and with a sport practice experience of 7.27 years on average (SD = 2.64). For to address this aim, we used the Psychological Characteristics related to the Sport Performance Questionnaire (CPRD) and the Psychological Skills Inventory for Sports (PSIS). In addition, regarding the evaluation of performance perception, an ad hoc short questionnaire was created, composed by one question addressed to the player and one directed to the coach. The results indicate that the group of players of the under-16 category obtained higher scores in all the psychological dimensions than the U-18 players, showing significant differences in Team Cohesion (p < 0.048). Regarding the degree of congruence between the player’s psychological features, and the player’s and coach’s performance perceptions, the results show statistically significant and negative correlations between the Team Cohesion factor and the athlete’s own outcome perception for the match #1 (rxy = -0.479; p < 0.001), and match #2 (rxy = -0.402; p < 0.01). The results of this study may contribute to establish the differences between different constellations of psychological characteristics according to the categories of competition and their relationship with the perception of performance. This knowledge can be used by sports professionals: coaches, psychologists, physical educators, etc., in order to help athletes to reach their maximum performance

Oligonucleotide-capped nanoporous anodic alumina biosensor as diagnostic tool for rapid and accurate detection of Candida auris in clinical samples

[EN] Candida auris has arisen as an important multidrug-resistant fungus because of several nosocomial outbreaks and elevated rates of mortality. Accurate and rapid diagnosis of C. auris is highly desired; nevertheless, current methods often present severe limitations and produce misidentification. Herein a sensitive, selective, and time-competitive biosensor based on oligonucleotide-gated nanomaterials for effective detection of C. auris is presented. In the proposed design, a nanoporous anodic alumina scaffold is filled with the fluorescent indicator rhodamine B and the pores blocked with different oligonucleotides capable of specifically recognize C. auris genomic DNA. Gate opening modulation and cargo delivery is controlled by successful DNA recognition. C. auris is detected at a concentration as low as 6 CFU/mL allowing obtaining a diagnostic result in clinical samples in one hour with no prior DNA extraction or amplification steps.The authors want to thank the Spanish Government (project RTI2018-100910-B-C41 (MCIU/AEI/FEDER, UE)), the Generalitat Valenciana (project PROMETEO/2018/024), Universitat Politecnica de Valencia-Instituto de Investigacion Sanitaria La Fe (AURISGATE project) and Centro de Investigacion Biomedica en Red en Bioingenieria, Biomateriales y Nanomedicina (NANOPATH AND CANDI-EYE projects) for support.

Chromoselective access to Z- or E- allylated amines and heterocycles by a photocatalytic allylation reaction

The most useful strategies for the alkylation of allylic systems are related to the Tsuji–Trost reaction or the use of different Lewis acids. Herein we report a photocatalytic approach for the allylation reaction of a variety of nucleophiles, such as heteroarenes, amines and alcohols. This method is compatible with a large variety of pyrroles and indoles, containing different substituents such as electron-withdrawing and electron-donating groups, unprotected nitrogen atoms and bromo derivatives. Moreover, this methodology enables the chromoselective synthesis of Z- or E-allylated compounds. While the use of UV-light irradiation has allowed the synthesis of the previously inaccessible Z-allylated products, E-isomers are prepared simply by changing both the light source to the visible region, and the catalytic system. Based on mechanistic and photochemical proofs, laser flash photolysis studies and DFT calculations, a rational mechanism is presentedFinancial support from the Spanish Government (CTQ2015-64561-R), CCC-UAM (computing time), and ERC (ERC-CG, 647550, 648319) is acknowledged.

TRPV4 Channels Promote Pathological, but Not Physiological, Cardiac Remodeling through the Activation of Calcineurin/NFAT and TRPC6

TRPV4 channels, which respond to mechanical activation by permeating Ca2+ into the cell, may play a pivotal role in cardiac remodeling during cardiac overload. Our study aimed to investigate TRPV4 involvement in pathological and physiological remodeling through Ca2+-dependent signaling. TRPV4 expression was assessed in heart failure (HF) models, induced by isoproterenol infusion or transverse aortic constriction, and in exercise-induced adaptive remodeling models. The impact of genetic TRPV4 inhibition on HF was studied by echocardiography, histology, gene and protein analysis, arrhythmia inducibility, Ca2+ dynamics, calcineurin (CN) activity, and NFAT nuclear translocation. TRPV4 expression exclusively increased in HF models, strongly correlating with fibrosis. Isoproterenol-administered transgenic TRPV4-/- mice did not exhibit HF features. Cardiac fibroblasts (CFb) from TRPV4+/+ animals, compared to TRPV4-/-, displayed significant TRPV4 overexpression, elevated Ca2+ influx, and enhanced CN/NFATc3 pathway activation. TRPC6 expression paralleled that of TRPV4 in all models, with no increase in TRPV4-/- mice. In cultured CFb, the activation of TRPV4 by GSK1016790A increased TRPC6 expression, which led to enhanced CN/NFATc3 activation through synergistic action of both channels. In conclusion, TRPV4 channels contribute to pathological remodeling by promoting fibrosis and inducing TRPC6 upregulation through the activation of Ca2+-dependent CN/NFATc3 signaling. These results pose TRPV4 as a primary mediator of the pathological response

Embarazo; Lactancia; CefaleaPregnancy; Breastfeeding; HeadacheEmbaràs; Lactància; CefaleaIntroducción La cefalea es uno de los motivos de consulta más comunes en neurología, siendo más frecuente durante la edad reproductiva. Por ello, es habitual encontrar en nuestras consultas pacientes embarazadas o en periodo de lactancia con dicha queja. Es importante conocer las opciones farmacológicas más seguras, cuáles no se deben emplear, así como cuándo sospechar cefaleas secundarias. Por este motivo, el Grupo de Estudio de Cefaleas de la Sociedad Española de Neurología ha elaborado una guía con las recomendaciones consensuadas acerca de los algoritmos diagnósticos y terapéuticos que se deben emplear durante el embarazo y la lactancia. Desarrollo Esta guía ha sido redactada por un grupo de jóvenes neurólogos con especial interés y experiencia en cefaleas en colaboración con la Junta Directiva del Grupo de Estudio de Cefaleas de la Sociedad Española de Neurología. Las recomendaciones se centran en los fármacos aconsejados en las cefaleas primarias más frecuentes, tanto en su fase aguda como preventiva. En una segunda parte se aborda cuándo sospechar y qué pruebas realizar ante una posible cefalea secundaria durante el embarazo y la lactancia. Conclusiones Esperamos que esta guía resulte de utilidad y permita su aplicación práctica en la consulta diaria. Asimismo, que sirva para actualizar y mejorar el conocimiento del manejo de las cefaleas durante estas etapas, para actuar con mayor confianza ante estas pacientes.Introduction Headache is one of the most common neurological complaints, and is most frequent during reproductive age. As a result, we are routinely faced with pregnant or breastfeeding women with this symptom in clinical practice. It is important to know which pharmacological choices are the safest, which should not be used, and when we should suspect secondary headache. To this end, the Spanish Society of Neurology's Headache Study Grouphas prepared a series of consensus recommendations on the diagnostic and therapeutic algorithms that should be followed during pregnancy and breastfeeding. Development This guide was prepared by a group of young neurologists with special interest and experience in headache, in collaboration with the Group's Executive Committee. Recommendations focus on which drugs should be used for the most frequent primary headaches, both during the acute phase and for prevention. The second part addresses when secondary headache should be suspected and which diagnostic tests should be performed in the event of possible secondary headache during pregnancy and breastfeeding. Conclusions We hope this guide will be practical and useful in daily clinical practice and that it will help update and improve understanding of headache management during pregnancy and breastfeeding, enabling physicians to more confidently treat these patients

A multiproxy study distinguishes environmental change from diagenetic alteration in the recent sedimentary record of the inner Cadiz Bay (SW Spain)

In this study, we reconstruct the recent environmental evolution of the inner Cadiz Bay using sedimentary records reaching back as far as AD 1700. We report lithological descriptions of the sediments and extensive mineralogical and geochemical analyses. An extraction technique that identifies different Fe phases provides an assessment of diagenetic alteration, which allows an estimation of the original organic matter inputs to the inner Cadiz Bay. Downcore variations in Corg/N ratios, δ13Corg and δ15N are related to changes in organic matter sources and the trophic state of the water column. The downcore records of selected trace metals (e.g. Pb, Zn and Cu) are interpreted to reflect changes in heavy metal pollution in the bay, while records of other elements (e.g. Mn and P) are likely overprinted by diagenetic alteration. Major environmental shifts took place during the 20th century, when the population around Cadiz Bay increased exponentially. Increases in sediment accumulation rates, organic matter inputs and heavy metal contents, in parallel with increases in δ13Corg and δ15N over this period, are interpreted as direct effects of the increasing anthropogenic influence in the area. The results of this study suggest that multiproxy approaches and detailed consideration of diagenetic overprinting are required to reconstruct past environmental conditions from coastal sediments

Prevalence of Symptomatic Axial Osteoarthritis Phenotypes in Spain and Associated Socio-Demographic, Anthropometric, and Lifestyle Variables

Epidemiology of RMDFinanciado para publicación en acceso aberto: Universidade da Coruña/CISUG[Abstract] Objective. Axial osteoarthritis (OA) is a common cause of back and neck pain, however, few studies have examined its prevalence. The aim was to estimate the prevalence and the characteristics of symptomatic axial OA in Spain. Methods. EPISER2016 is a cross-sectional multicenter population-based study of people aged 40 years or older. Subjects were randomly selected using multistage stratified cluster sampling. Participants were contacted by telephone to complete rheumatic disease screening questionnaires. Two phenotypes were analyzed, patients with Non-exclusive axial OA (NEA-OA) and Exclusive axial OA (EA-OA). To calculate the prevalence and its 95% confidence interval (CI), the sample design was considered and weighting was calculated according to age, sex and geographic origin. Results. Prevalence of NEA-OA by clinical or clinical-radiographic criteria was 19.17% (95% CI: 17.82–20.59). The frequency of NEA-OA increased with age (being 3.6 times more likely in patients aged 80 s or more than in those between 40 and 49 years) and body mass index. It was significantly more frequent in women, as well as in the center of Spain. It was less frequent in those with a higher level of education. Lumbar OA was more frequent than cervical OA. This difference grew with increasing age and was not associated with gender. It was also greater in overweight and obese subjects. Conclusions. This is the first study on the prevalence of axial OA phenotypes in Europe describing the associated socio-demographic, anthropometric, and lifestyle variables.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

The Spanish Society of Rheumatology carried out the EPISER2000 study in 2000 to determine the prevalence of osteoarthritis and other rheumatic diseases in the Spanish population. Recent sociodemographic changes and lifestyle habits in Spain justified updating the epidemiological data on osteoarthritis and other rheumatic diseases (EPISER2016-study). Objective. To estimate the prevalence of symptomatic osteoarthritis of the cervical spine, lumbar spine, hip, knee and hand in the adult population in Spain. Material and methods. Cross-sectional population-based study. A multistage and stratified random cluster sampling was carried out. The participants were contacted by telephone to complete an osteoarthritis screening questionnaire. A rheumatologist confirmed or discarded the diagnosis. The ACR-clinical-criteria were used to diagnose hand-osteoarthritis and the ACR-clinical-radiological criteria to diagnose knee- and hip-osteoarthritis. To estimate the prevalence and its 95% confidence interval, weights were calculated according to the probability of selection in each of the sampling stages. Results. The prevalence of osteoarthritis in Spain in one or more of the locations studied was 29.35%. The prevalence of cervical-osteoarthritis was 10.10% and of lumbar-osteoarthritis 15.52%. Both are more frequent in women and at older ages, as well as in people with low levels of education and obesity. The prevalence of hip-osteoarthritis was 5.13%, that of knee-osteoarthritis 13.83%, these are associated with female sex, overweight and obesity. The prevalence of hand osteoarthritis was 7.73%. It is more frequent in women, who are obese, with a low educational level and who are older. Conclusion. The EPISER2016 study is the first to analyse the prevalence of symptomatic osteoarthritis in 5 locations (cervical, lumbar, knee, hip and hands) in Spain. Lumbar spine osteoarthritis is the most prevalent.EPISER2016 ha sido financiado por Celgene, Laboratorios, Gebro Pharma, Merck Sharp and Dohme de España, Pfizer y Sanofi-Aventis.

Sirtuin-2, NAD-Dependent Deacetylase, is a new potential therapeutic target for HIV-1 infection and HIV-related neurological dysfunction

The implementation and access to combined antiretroviral treatment (cART) have dramatically improved the quality of life of people living with HIV (PLWH). However, some comorbidities, such as neurological disorders associated with HIV infection still represent a serious clinical challenge. Soluble factors in plasma that are associated with control of HIV replication and neurological dysfunction could serve as early biomarkers and as new therapeutic targets for this comorbidity. We used a customized antibody array for determination of blood plasma factors in 40 untreated PLWH with different levels of viremia and found sirtuin-2 (SIRT2), an NAD-dependent deacetylase, to be strongly associated with elevated viral loads and HIV provirus levels, as well as with markers of neurological damage (a-synuclein [SNCA], brain-derived neurotrophic factor [BDNF], microtubule-associated protein tau [MAPT], and neurofilament light protein [NFL]). Also, longitudinal analysis in HIV-infected individuals with immediate (n = 9) or delayed initiation (n = 10) of cART revealed that after 1 year on cART, SIRT2 plasma levels differed between both groups and correlated inversely with brain orbitofrontal cortex involution. Furthermore, targeting SIRT2 with specific small-molecule inhibitors in in vitro systems using J-LAT A2 and primary glial cells led to diminished HIV replication and virus reactivation from latency. Our data thus identify SIRT2 as a novel biomarker of uncontrolled HIV infection, with potential impact on neurological dysfunction and offers a new therapeutic target for HIV treatment and cure. IMPORTANCE Neurocognitive disorders are frequently reported in people living with HIV (PLWH) even with the introduction of combined antiretroviral treatment (cART). To identify biomarkers and potential therapeutic tools to target HIV infection in peripheral blood and in the central nervous system (CNS), plasma proteomics were applied in untreated chronic HIV-infected individuals with different levels of virus control. High plasma levels of sirtuin-2 (SIRT2), an NAD+ deacetylase, were detected in uncontrolled HIV infection and were strongly associated with plasma viral load and proviral levels. In parallel, SIRT2 levels in the peripheral blood and CNS were associated with markers of neurological damage and brain involution and were more pronounced in individuals who initiated cART later in infection. In vitro infection experiments using specific SIRT2 inhibitors suggest that specific targeting of SIRT2 could offer new therapeutic treatment options for HIV infections and their associated neurological dysfunction

Aptamer-capped nanoporous anodic alumina for SARS-CoV-2 spike protein detection

The COVID-19 pandemic, which began in 2019, has highlighted the importance of testing and tracking infected individuals as a means of mitigating the spread of the virus. In this context, the development of sensitive and rapid methods for the detection of SARS-CoV-2, the virus responsible for COVID-19, is crucial. Herein, a biosensor based on oligonucleotide-gated nanomaterials for the specific detection of SARS-CoV-2 spike protein is presented. The sensing system consists of a nanoporous anodic alumina disk loaded with the fluorescent indicator rhodamine B and capped with a DNA aptamer that selectively binds the SARS-CoV-2 spike protein. The system is initially evaluated using pseudotype virus systems based on vesicular stomatitis virus carrying different SARS-CoV-2 S-proteins on their surface. When the pseudotype virus is present, the cap of the solid is selectively removed, triggering the release of the dye from the pore voids to the medium. The nanodevice demonstrated its ability to detect pseudotype virus concentrations as low as 7.5·103 PFU mL. In addition, the nanodevice is tested on nasopharyngeal samples from individuals suspected of having COVID-19.This study was supported by the Spanish Government (projects PID2021-126304OB-C41, and PID2021-122875OB-100 (MCUI/AEI/FEDER, UE)), the Generalitat Valenciana (project no.2 RD 180/2020, CIPROM/2021/007), Supera COVID-19 Fund (DIACOVID project), the Universitat Politècnica de València−Instituto de Investigación Sanitaria La Fe (IIS-LaFe) (SARS-COV-2-SEEKER and VISION-COV projects), and by the European Commission –NextGenerationEU, through CSIC's Global Health Platform (PTI Salud Global) to Ron Geller.
