    El presente trabajo de investigación de tipo correlacional buscó determinar la relación entre el funcionamiento familiar con el desarrollo psicomotor del preescolar de la Institución Educativa La Portada. Cajamarca, 2021 considerando 28 niños. Se utilizaron dos instrumentos el cuestionario de Funcionamiento Familiar FF- SIL y el TEPSI para valorar el desarrollo psicomotor. Se obtuvo como resultados que del 100% (28) de los preescolares el 57.1% (15) pertenecen a una familia disfuncional y el 42.9% (13) pertenecen a una familia moderamente funcional, en los pre escolares evaluados no se presenta la familia funcional ni severamente disfuncional y en relación al desarrollo psicomotor el 85,7% presenta un desarrollo normal y el 14,3% están en riesgo del desarrollo, no se encontró pre escolares con retraso en el desarrollo. Para contrastar la hipótesis se utilizó Chi – cuadrado de Pearson el nivel de significancia fue de 0,000 < 0,05 indicando que se rechaza la hipótesis nula, es decir el funcionamiento familiar se relaciona con el desarrollo psicomotor del preescolar.The present correlational research work sought to determine the relationship between family functioning with the psychomotor development of the preschooler of the La Portada Educational Institution. Cajamarca, 2021 considering 28 children. Two instruments, the FF-SIL Family Functioning Questionnaire and the TEPSI, were used to assess psychomotor development. It was obtained as results that of 100% (28) of the preschoolers, 57.1% (15) belong to a dysfunctional family and 42.9% (13) belong to a moderately functional family, in the evaluated preschoolers the functional family is not present nor severely dysfunctional and in relation to psychomotor development, 85.7% have normal development and 14.3% are at risk of development, no preschoolers with developmental delay were found. To test the hypothesis, Pearson's Chi-square was used, the level of significance was 0.000 < 0.05, indicating that the null hypothesis is rejected, that is, family functioning is related to the psychomotor development of preschoolers.Tesi

    A novel control strategy for enhancing biological N-removal in a granular sequencing batch reactor : a model-based study

    Get PDF
    Biological nitrogen removal in aerobic granular sequencing batch reactors is sensitively affected by process conditions (e.g. dissolved oxygen (DO) concentration, nitrogen loading rate (NLR), influent C/N ratio, among others). The variation of one of these process conditions affects the others, because often they are tightly linked. These interrelationships are a drawback for the experimental assessment of the target domain of process conditions required to enhance N-removal. Here, we have developed a model to determine the guidelines to design an automatic control strategy with the final aim of enhancing biological N-removal in a granular sequencing batch reactor. The model was first calibrated with experimental data from a granular sequencing batch reactor treating swine wastewater. Specific simulations were designed to elucidate the effect of DO concentration (0.5-8 mg O₂ L⁻¹), granule size (0.5-3.5 mm), influent C/N ratio (4-10 g O₂g⁻¹ N) and NLR (0.41-0.82 g N L⁻¹ d⁻¹) on the nitrification- enitrification efficiency. Simulation results showed that, in general, high N-removal efficiencies (from 70% to 85%) could be obtained only setting the appropriate DO concentration. That appropriate DO concentration could be easily found based on effluent ammonium concentration. Those results were used to propose a control strategy to enhance N-removal efficiencies. The control strategy was based on a closed DO loop with variable DO set-point. The DO set-point was established at a constant value for the whole cycle (i.e. once per cycle), based on the on-line measurement of ammonium concentration at the end of the previous cycle

    Does retraction after misconduct have an impact on citations? A pre–post study

    Get PDF
    Background: Retracted articles continue to be cited after retraction, and this could have consequences for the scientific community and general population alike. This study was conducted to analyse the association of retraction on citations received by retracted papers due to misconduct using two-time frames: during a postretraction period equivalent to the time the article had been in print before retraction; and during the total postretraction period. Methods: Quasiexperimental, pre-post evaluation study. A total of 304 retracted original articles and literature reviews indexed in MEDLINE fulfilled the inclusion criteria. Articles were required to have been published in a journal indexed in MEDLINE from January 2013 through December 2015 and been retracted between January 2014 and December 2016. The main outcome was the number of citations received before and after retraction. Results were broken down by journal quartile according to impact factor and the most cited papers during the preretraction period were specifically analysed. Results: There was an increase in postretraction citations when compared with citations received preretraction. There were some exceptions however: first, citations received by articles published in first-quartile journals decreased immediately after retraction (p<0.05), only to increase again after some time had elapsed; and second, postretraction citations decreased significantly in the case of articles that had received many citations before their retraction (p<0.05). Conclusions: The results indicate that retraction of articles has no association on citations in the long term, since the retracted articles continue to be cited, thus circumventing their retraction

    Ramsay Hunt syndrome (RHS) consists of peripheral facial palsy associated with a vesicular erythematous rash in the ear (auricular zoster) or in the mouth. Syndrome of inappropriate secretion of antidiuretic hormone(SIADH) is the most frequent cause of hyponatremia with normovolaemia and has occasionally been described in association with RHS. We present the case of a 59-year-old woman diagnosed with RHS associated with SIADH. This association can be serious, so it requires early diagnosis and treatment.El síndrome de Ramsay Hunt (RHS) consiste en una parálisis facial periférica asociada a un rash eritematoso vesicular en el oído (zóster auricular) o en la boca. El síndrome de secreción inadecuada de hormona antidiurética (SIADH) es la causa más frecuente de hiponatremia con normovolemia y ocasionalmente se ha descrito asociado al RHS. Se presenta el caso de una mujer de 59 años a la que diagnosticamos de RHS asociado a SIADH. Esta asociación puede ser grave por lo que requiere un diagnóstico y tratamiento tempranos

    Kimura disease should be suspected when there are lymphoid masses or nodules in the head and neck, with subcutaneous cellular tissue involvement and regional lymphadenopathy, with minor inflammation and few systemic symptoms. It is usually associated with blood eosinophilia and elevated serum IgE. Even without treatment, it has a good prognosis, although recurrence is common. We present the case of a 66-year-old Caucasian male with a rapidly appearing laterocervical mass whose final diagnosis was made by biopsy. Biopsy showed mixed findings of Kimura disease and angiolymphoid hyperplasia with eosinophilia (ALHE), once thought to be the same disorder.La enfermedad de Kimura se debe sospechar ante masas o nódulos linfoides en cabeza y cuello, con afectación del tejido celular subcutáneo y linfadenopatías regionales, con poca inflamación y pocos síntomas sistémicos, habitualmente acompañadas de eosinofilia periférica y elevación de IgE sérica. Presenta buen pronóstico incluso sin tratamiento, aunque con tendencia a la recidiva. Se presenta el caso de un varón caucásico de 66 años con una masa laterocervical de rápida aparición cuyo diagnóstico final se realizó con la biopsia, en la que se encontraron hallazgos mixtos con hiperplasia angiolinfoide con eosinofilia (HALE), que antes se pensaba que era la misma entidad

    Altres ajuts: This project was partially supported by grants from Xunta de Galicia (Consellería Educación: GRC2014/027 and IN607A2018/3), Spanish Research Network on Cerebrovascular Diseases RETICS-INVICTUS PLUS (RD16/0019), and by the European Union FEDER program.The main objective of this research work was to study the association of serum levels of growth factors (GF) and SDF-1α with the functional outcome and reduction of lesion volume in ischemic stroke patients. In this multicenter study, 552 patients with non-lacunar stroke (male, 62.1%; mean age, 68.2 ± 11.4) were included within 24 h from symptom onset. The main outcome variable was good functional outcome (modified Rankin Scale [mRS] ≤ 2) at 12 months. Secondary outcome variable was infarct volume (in mL) after 6 ± 3 months. Serum levels of VEGF, Ang-1, G-CSF, BDNF, and SDF-1α were measured by ELISA at admission, 7 ± 1 days, at 3 ± 1 months, and 12 ± 3 months. Except for BDNF, all GF and SDF-1α serum levels showed a peak value at day 7 and remained elevated during the first 3 months (all p < 0.01). High serum levels at day 7 of VEGF (OR, 19.3), Ang-1 (OR, 14.7), G-CSF (OR, 9.6), and SDF-1α (OR, 28.5) were independently associated with good outcome at 12 months (all p < 0.0001). On the other hand, serum levels of VEGF (B, − 21.4), G-CSF (B, − 14.0), Ang-1 (B, − 13.3), and SDF-1α (B, − 44.6) measured at day 7 were independently associated with lesion volume at 6 months (p < 0.01). In summary, high serum levels of VEGF, Ang-1, G-CSF, and SDF-1α at day 7 and 3 months after ischemic stroke are associated with good functional outcome and smaller residual lesion at 1 year of follow-up

    Response of Quercus ilex seedlings to Phytophthora spp. root infection in a soil infestation test

    Full text link
    [EN] Phytophthora species are the main agents associated with oak (Quercus spp.) decline, together with the changing environmental conditions and the intensive land use. The aim of this study was to evaluate the susceptibility of Quercus ilex to the inoculation with eight Phytophthora species. Seven to eight month old Q. ilex seedlings grown from acorns, obtained from two Spanish origins, were inoculated with P. cinnamomi, P. cryptogea, P. gonapodyides, P. megasperma, P. nicotianae, P. plurivora, P. psychrophila and P. quercina. All Phytophthora inoculated seedlings showed decline and symptoms including small dark necrotic root lesions, root cankers, and loss of fine roots and tap root. The most aggressive species were P. cinnamomi, P. cryptogea, P. gonapodyides, P. plurivora and P. psychrophila followed by P. megasperma., while Phytophthora quercina and P. nicotianae were the less aggressive species. Results obtained confirm that these Phytophthora species could constituted a threat to Q. ilex ecosystems and the implications are further discussed.The authors are grateful to A. Solla and his team from the Centro Universitario de Plasencia-Universidad de Extremadura (Spain) for helping in the acorns collection and to the CIEF (Centro para la Investigación y Experimentación Forestal, Generalitat Valenciana, Valencia, Spain) for providing the acorns.
