Estudio relacional de la práctica deportiva en escolares según el género

Insomuch as physical activity has taken a center stage as a way to prevent sedentary lifestyles, it is essential to know what are the sports which are played by schoolchildren outside schools. Therefore, this descriptive and cross-sectional research, conducted on a sample of 818 schoolchildren, has as a main objective to establish sport habits according to gender, which has acted as a moderating factor throughout history. The results showed that female schoolchildren practiced mainly individual sports and as a leisurely activity while men preferred collective and federated sports. Moreover, the level of sport practice determined that male students practiced more sports than female students, so in a greater number of weekly days and longer sessions. Therefore, this research demonstrates that the sport, which is played by children, depends on gender, as well as the necessity of matching this practice avoiding stereotypes and sedentary lifestyles.Dado que la actividad física ha tomado protagonismo como medio para evitar estilos de vida sedentarios, resulta imprescindible conocer cuáles son los deportes practicados por los escolares fuera del horario escolar. Este estudio de carácter descriptivo y de corte transversal, realizado sobre 818 escolares, tiene como objetivo principal establecer hábitos de práctica deportiva en función del género, el cual ha actuado como factor modulador a lo largo de la historia. Los resultados determinaron que los escolares de género femenino practicaban principalmente deportes individuales y a modo de hobby, mientras que los varones lo hacían de forma colectica y federada. Asimismo, el nivel de práctica deportiva determinó que ellos practicaban más deportes que ellas, haciéndolo más días semanales y en sesiones de mayor duración. Como conclusión, se demuestran diferencias en el deporte practicado según el género, así como la necesidad de igualar esta práctica evitando estereotipos y estilos de vida sedentarios. 

High efficacy of Sofosbuvir plus Simeprevir in a large cohort of Spanish cirrhotic patients infected with genotypes 1 and 4

[Abstract] Background and Aims. Hepatitis C (HCV) therapy with Sofosbuvir (SOF)/Simeprevir (SMV) in clinical trials and real‐world clinical practice, showed high rates of sustained virological response (SVR) in non‐cirrhotic genotype (GT)‐1 and GT‐4 patients. These results were slightly lower in cirrhotic patients. We investigated real‐life effectiveness and safety of SOF/SMV with or without ribavirin (RBV) in a large cohort of cirrhotic patients. Methods. This collaborative multicentre study included data from 968 patients with cirrhosis infected with HCV‐GT1 or 4, treated with SOF/SMV±RBV in 30 centres across Spain between January‐2014 and December‐2015. Demographic, clinical, virological and safety data were analysed. Results. Overall SVR was 92.3%; the majority of patients were treated with RBV (62%) for 12 weeks (92.4%). No significant differences in SVR were observed between genotypes (GT1a:94.3%; GT1b:91.7%; GT4:91.1%). Those patients with more advanced liver disease (Child B/C, MELD≥10) or portal hypertension (platelet count≤100×109/L, transient elastography≥21 Kpa) showed significantly lower SVR rates (84.4%‐91.9%) than patients with less advanced liver disease (93.8%‐95.9%, P<.01 in all cases). In the multivariate analysis, the use of RBV, female gender, baseline albumin≥35 g/L, MELD<10 and lack of exposure to a triple therapy regimen were independent predictors of SVR (P<.05). Serious adverse events (SAEs) and SAE‐associated discontinuation events occurred in 5.9% and 2.6%. Conclusions. In this large cohort of cirrhotic patients managed in the real‐world setting in Spain, SOF/SMV±RBV yielded to excellent SVR rates, especially in patients with compensated liver cirrhosis. In addition, this combination showed to be safe, with low rates of SAEs and early discontinuations.Instituto de Salud Carlos III; PI15/0015

Markers of endothelial damage in patients with chronic kidney disease on hemodialysis

Patients with Stage 5 chronic kidney disease who are on hemodialysis (HD) remain in a chronic inflammatory state, characterized by the accumulation of uremic toxins that induce endothelial damage and cardiovascular disease (CVD). Our aim was to examine microvesicles (MVs), monocyte subpopulations, and angiopoietins (Ang) to identify prognostic markers in HD patients with or without diabetes mellitus (DM). A total of 160 prevalent HD patients from 10 centers across Spain were obtained from the Biobank of the Nephrology Renal Network (Madrid, Spain): 80 patients with DM and 80 patients without DM who were matched for clinical and demographic criteria. MVs from plasma and several monocyte subpopulations (CD142+/CD16+, CD14+/CD162+) were analyzed by flow cytometry, and the plasma concentrations of Ang1 and Ang2 were quantified by ELISA. Data on CVD were gathered over the 5.5 yr after these samples were obtained. MV level, monocyte subpopulations (CD14+/CD162+ and CD142+/CD16+), and Ang2-to-Ang1 ratios increased in HD patients with DM compared with non-DM patients. Moreover, MV level above the median (264 MVs/µl) was associated independently with greater mortality. MVs, monocyte subpopulations, and Ang2-to-Ang1 ratio can be used as predictors for CVD. In addition, MV level has a potential predictive value in the prevention of CVD in HD patients. These parameters undergo more extensive changes in patients with DM.Support for this work was provided by Plan Nacional de IDi Proyectos de Investigación en Salud of Instituto de Salud Carlos III (ISCIII)–Subdirección General de Evaluación, Fondos de desarrollo regional (FEDER; PI11/01536, PI12/01489, PI14/00806, PI15/01785); Junta de Andalucía grants (P010-CTS-6337, P11-CTS-7352); and Fundación Nefrológica.

Higher COVID-19 pneumonia risk associated with anti-IFN-α than with anti-IFN-ω auto-Abs in children

We found that 19 (10.4%) of 183 unvaccinated children hospitalized for COVID-19 pneumonia had autoantibodies (auto-Abs) neutralizing type I IFNs (IFN-alpha 2 in 10 patients: IFN-alpha 2 only in three, IFN-alpha 2 plus IFN-omega in five, and IFN-alpha 2, IFN-omega plus IFN-beta in two; IFN-omega only in nine patients). Seven children (3.8%) had Abs neutralizing at least 10 ng/ml of one IFN, whereas the other 12 (6.6%) had Abs neutralizing only 100 pg/ml. The auto-Abs neutralized both unglycosylated and glycosylated IFNs. We also detected auto-Abs neutralizing 100 pg/ml IFN-alpha 2 in 4 of 2,267 uninfected children (0.2%) and auto-Abs neutralizing IFN-omega in 45 children (2%). The odds ratios (ORs) for life-threatening COVID-19 pneumonia were, therefore, higher for auto-Abs neutralizing IFN-alpha 2 only (OR [95% CI] = 67.6 [5.7-9,196.6]) than for auto-Abs neutralizing IFN-. only (OR [95% CI] = 2.6 [1.2-5.3]). ORs were also higher for auto-Abs neutralizing high concentrations (OR [95% CI] = 12.9 [4.6-35.9]) than for those neutralizing low concentrations (OR [95% CI] = 5.5 [3.1-9.6]) of IFN-omega and/or IFN-alpha 2

Novel mutation in STXBP1 gene in a patient with non-lesional Ohtahara syndrome

Introduction: Ohtahara syndrome (OS, OMIM #308350, ORPHA1934) is an early-onset epileptic encephalopathy (EOEE) characterised by spasms, intractable seizures, suppression-burst pattern on the electroencephalogram, and severe psychomotor retardation. Mutations in STXBP1 – a gene that codes for syntaxin binding protein 1 and is involved in synaptic vesicle exocytosis – has been identified in most patients with OS. Patient and results: We report the case of a 19-month-old child with OS who displays a previously unreported mutation in STXBP1 (c.1249+2T>C, G417AfsX7). This mutation is located in a donor splice site and eliminates exon 14, resulting in a truncated protein. Conclusion: This previously unreported STXBP1 mutation in a subject with Ohtahara syndrome and non-lesional magnetic resonance imaging (MRI) broadens the mutational spectrum associated with this devastating epileptic syndrome. Resumen: Introducción: El síndrome de Ohtahara (SO, OMIM #308350, ORPHA1934) es una encefalopatía epiléptica de inicio precoz (EEIP) caracterizada por espasmos, crisis epilépticas intratables, un trazado electroencefalográfico de brote-supresión y retraso psicomotor grave. En la mayoría de los pacientes con SO se han identificado mutaciones en el gen STXBP1, que codifica para la proteína de unión a sintaxina 1 y que está implicado en el mecanismo de exocitosis de las vesículas sinápticas. Paciente y resultados: Se presenta el caso clínico de un varón de 19 meses de edad diagnosticado de SO en el que se ha identificado una mutación no descrita (c.1249+2T>C, G417AfsX7) en el gen STXBP1. La mutación está localizada en uno de los sitios donadores implicados en el procesamiento del ARNm del gen, lo que produce la pérdida del exón 14 y el posterior truncamiento de la proteína que codifica. Conclusiones: Esta nueva mutación en el gen STXBP1, identificada en un paciente sin lesión cerebral estructural subyacente, amplía el espectro mutacional asociado a este devastador síndrome epiléptico.
