Violencia en centros de educación media superior: prácticas prosociales como mecanismo de solución

Violence in the school environment is characterized by all those forms of abuse that take place within schools and, of course, around it, which is suffered by students and carried out by other students, teachers and anyone who is find within the educational setting. Violence in schools has been recognized worldwide as a serious problem, since 2 out of 10 students have experienced some type of bullying or school violence. The high school student has a diminished moral development that is linked to antisocial or criminal behavior. The moral disconnect has to do with learning, which has a close relationship with family, friends or the community and, of course, school. Thus, when prosocial behaviors are adopted and appropriated in daily life, environments of respect and non-violence are promoted, that is, they defend others in situations of bullying among peers, try to help, listen to the other about the problems that it addresses, that is, being empathetic in the full extent of the word, is an important variable that is related to the defense of bullying. Therefore, teaching prosocial behavior in higher education spaces is important since it not only promotes the development of positive aspects among individuals, but also favorable or positive consequences of behaviors mostly based on support or help towards others.La violencia en el ámbito escolar se caracteriza por todas aquellas formas de maltrato que se gestan dentro de las escuelas y, desde luego, alrededor de ella, de la cual es padecida por estudiantes y llevadas a cabo por otros estudiantes, profesores y cualquiera que se encuentre dentro del escenario educativo. La violencia en las escuelas se ha reconocido a nivel mundial como una problemática seria, pues 2 de cada 10 estudiantes ha experimentado algún tipo de acoso o violencia escolar. Se realizó un análisis a partir de la revisión de artículos indexados en distintas fuentes nacionales e internacionales, utilizando palabras clave, se analizaron los factores y violencia en el ámbito educativo como: acoso escolar, disminución del desarrollo moral en los jóvenes y las conductas prosociales, la cual funciona como mecanismo para promover un desarrollo positivo en los estudiantes y con ello poder evitar que se susciten las conductas violentas que causan la violencia escolar. Como resultado, se obtuvo que, cuando se adoptan y se apropian las conductas prosociales en la vida diaria, se promueven ambientes de respeto y no violencia, esto es, se defienden a los demás ante situaciones de acoso entre los compañeros. Se concluye que, al enseñar la conducta prosocial en los espacios de educación medio superior es importante ya que, no solo promueve el desarrollo de aspectos positivos entre los individuos, sino también se experimentan consecuencias favorables o positivas de los comportamientos mayormente basados en el apoyo o ayuda hacia los demás

Evaluating satisfaction with teaching innovation, its relationship to academic performance and the application of a video-based microlearning

Aim: To develop and validate a questionnaire to assess satisfaction with teaching innovation, assess the student satisfaction with a video-based microlearning intervention in its video-based modality and to verify its impact on academic performance. Design: A descriptive cross-sectional study was conducted. The study used the COSMIN checklist for studies on measurement instruments. Methods: One hundred and ten nursing students from Salus Infirmorum University Centre (Andalusia, Spain) participated in the study. The items of the instrument were designed based on a literature review and its validity and stability were analysed. After that, 6 weeks of video-based microlearning intervention were implemented. Then students were asked to fill the satisfaction questionnaire and then took the subject exam. Results: The resulting questionnaire consisted of 5 items with only one dimension. The questionnaire showed good validity and reliability. A direct correlation was observed between satisfaction with the video-based microlearning intervention and the marks of the subject exam.11 página

Pathogenesis of Periodontal Disease

Inflammation is a physiological response of the innate immune system against several endogenous or exogenous stimuli. Inflammation begins with an acute pattern; however, it can become chronic by activating the adaptive immune response through cellular and noncellular mechanisms. The main etiologic factor of periodontal disease is bacteria which substantially harbor the human oral cavity. The most common periodontal diseases are gingivitis and periodontitis, whose main characteristic is inflammation. The knowledge of how immune mechanisms and inflammatory responses are regulated is fundamental to understanding the pathogenesis of periodontal disease. The purpose of this chapter is to show the current panorama of the immunological mechanisms involved in the pathogenesis of periodontal disease

The long-term failure of RYGB surgery in improving T2DM is related to hyperinsulinism.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) is the gold standard method for bariatric surgery and leads to substantial improvements in Type 2 Diabetes mellitus. However, many patients experience relapses in diabetes five years after undergoing this aggressive surgical procedure. We focus on beta-cell population changes and absorptive intestinal consequences after RYGB in a healthy nonobese animal model after a long survival period. METHODS: For our purpose, we use three groups of Wistar rats: RYGB-operated, surgical control (Sham) and fasting control. We measure alpha-, beta-cell mass; transcription (Arx, and Pdx-1) and proliferation (Ki67) factors; glucose tolerance and insulin release after oral glucose tests; histological adaptive changes in the jejunum; and intestinal glucose transporters. RESULTS: Our results showed an early increase in insulin secretion after surgery, that decrease at the end of the study. The beta-cell mass reduces twenty-four weeks after RYGB, which coincides with decrease of Pdx-1 transcription promoter factor. These was coincident with an increase in alpha-mass and a high expression of Arx in RYGB group. CONCLUSIONS: The analysis of all data showed beta-cell mass transdifferentiation into alpha-cell mass in RYGB rats. Due to long-term exhaustion of the beta-cell population by hyperinsulinism derived from digestive tract adaptation to surgery. Copyright © 2021 The Author(s). Published by Elsevier GmbH..

Risk factors for developing ventilator-associated lower respiratory tract infection in patients with severe COVID-19:a multinational, multicentre study, prospective, observational study

Around one-third of patients diagnosed with COVID-19 develop a severe illness that requires admission to the Intensive Care Unit (ICU). In clinical practice, clinicians have learned that patients admitted to the ICU due to severe COVID-19 frequently develop ventilator-associated lower respiratory tract infections (VA-LRTI). This study aims to describe the clinical characteristics, the factors associated with VA-LRTI, and its impact on clinical outcomes in patients with severe COVID-19. This was a multicentre, observational cohort study conducted in ten countries in Latin America and Europe. We included patients with confirmed rtPCR for SARS-CoV-2 requiring ICU admission and endotracheal intubation. Only patients with a microbiological and clinical diagnosis of VA-LRTI were included. Multivariate Logistic regression analyses and Random Forest were conducted to determine the risk factors for VA-LRTI and its clinical impact in patients with severe COVID-19. In our study cohort of 3287 patients, VA-LRTI was diagnosed in 28.8% [948/3287]. The cumulative incidence of ventilator-associated pneumonia (VAP) was 18.6% [610/3287], followed by ventilator-associated tracheobronchitis (VAT) 10.3% [338/3287]. A total of 1252 bacteria species were isolated. The most frequently isolated pathogens were Pseudomonas aeruginosa (21.2% [266/1252]), followed by Klebsiella pneumoniae (19.1% [239/1252]) and Staphylococcus aureus (15.5% [194/1,252]). The factors independently associated with the development of VA-LRTI were prolonged stay under invasive mechanical ventilation, AKI during ICU stay, and the number of comorbidities. Regarding the clinical impact of VA-LRTI, patients with VAP had an increased risk of hospital mortality (OR [95% CI] of 1.81 [1.40-2.34]), while VAT was not associated with increased hospital mortality (OR [95% CI] of 1.34 [0.98-1.83]). VA-LRTI, often with difficult-to-treat bacteria, is frequent in patients admitted to the ICU due to severe COVID-19 and is associated with worse clinical outcomes, including higher mortality. Identifying risk factors for VA-LRTI might allow the early patient diagnosis to improve clinical outcomes. Trial registration: This is a prospective observational study; therefore, no health care interventions were applied to participants, and trial registration is not applicable

La formación en el afecto, en los valores, en la moral... ¿Qué mejor ámbito para su análisis e incorporación a una práctica social y pedagógica coherente con ello que la vida cotidiana?...la vida cotidiana escolar o familiar, personal o colectiva. Los afectos, y éstos como fundamento de una educación orientada hacia la formación de sujetos históricos, hombres y mujeres con responsabilidad, compromiso y conciencia sociales, corresponden a una de las formas de contacto cotidiano más importantes, especialmente por la intensidad de los sentimientos que en ellas se establecen: nos referimos a las relaciones entre sujetos. Constituyen expresiones suyas, las relaciones de amistad, el amor, pero también el adío. Aunque una valoración de tales sentimientos solo se logra mediante el análisis del contenido y la motivación — sobre todo de orden moral— de tales sentimientos, podemos afirmar, en general, siguiendo a Agnes Heller que el desarrollo de la moral, de la política, del arte y de la ciencia, es inconcebible sin grandes amores y grandes odios’’.Training in affection, in values, in morality... What better environment for its analysis and incorporation into a coherent social and pedagogical practice than daily life?... daily school or family, personal life or collective. Affections, and these as the foundation of an education oriented towards the formation of historical subjects, men and women with social responsibility, commitment and conscience, correspond to one of the most important forms of daily contact, especially due to the intensity of the feelings that in they are established: we refer to the relations between subjects. Their expressions are friendships, love, but also goodbye. Although an assessment of such feelings can only be achieved through analysis of content and motivation — especially of moral order— of such feelings, we can affirm, in general, following Agnes Heller that the development of morality, politics, art and science is inconceivable without great loves and great hates.Modalidad Presencia

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism

Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio

Impact of interstitial lung disease on the survival of systemic sclerosis with pulmonary arterial hypertension

To assess severity markers and outcomes of patients with systemic sclerosis (SSc) with or without pulmonary arterial hypertension (PAH-SSc/non-PAH-SSc), and the impact of interstitial lung disease (ILD) on PAH-SSc. Non-PAH-SSc patients from the Spanish SSc registry and PAH-SSc patients from the Spanish PAH registry were included. A total of 364 PAH-SSc and 1589 non-PAH-SSc patients were included. PAH-SSc patients had worse NYHA-functional class (NYHA-FC), worse forced vital capacity (FVC) (81.2 +/- 20.6% vs 93.6 +/- 20.6%, P < 0.001), worse tricuspid annular plane systolic excursion (TAPSE) (17.4 +/- 5.2 mm vs 19.9 +/- 6.7 mm, P < 0.001), higher incidence of pericardial effusion (30% vs 5.2%, P < 0.001) and similar prevalence of ILD (41.8% vs. 44.9%). In individuals with PAH-SSc, ILD was associated with worse hemodynamics and pulmonary function tests (PFT). Up-front combination therapy was used in 59.8% and 61.7% of patients with and without ILD, respectively. Five-year transplant-free survival rate was 41.1% in PAH-SSc patients and 93.9% in non-PAH-SSc patients (P < 0.001). Global survival of PAH-SSc patients was not affected by ILD regardless its severity. The multivariate survival analysis in PAH-SSc patients confirmed age at diagnosis, worse NYHA-FC, increased PVR, reduced DLCO, and lower management with up-front combination therapy as major risk factors. In conclusion, in PAH-SSc cohort risk of death was greatly increased by clinical, PFT, and hemodynamic factors, whereas it was decreased by up-front combination therapy. Concomitant ILD worsened hemodynamics and PFT in PAH-SSc but not survival regardless of FVC impairment

Gating of a pH-Sensitive K2P Potassium Channel by an Electrostatic Effect of Basic Sensor Residues on the Selectivity Filter

K+ channels share common selectivity characteristics but exhibit a wide diversity in how they are gated open. Leak K2P K+ channels TASK-2, TALK-1 and TALK-2 are gated open by extracellular alkalinization. The mechanism for this alkalinization-dependent gating has been proposed to be the neutralization of the side chain of a single arginine (lysine in TALK-2) residue near the pore of TASK-2, which occurs with the unusual pKa of 8.0. We now corroborate this hypothesis by transplanting the TASK-2 extracellular pH (pHo) sensor in the background of a pHo-insensitive TASK-3 channel, which leads to the restitution of pHo-gating. Using a concatenated channel approach, we also demonstrate that for TASK-2 to open, pHo sensors must be neutralized in each of the two subunits forming these dimeric channels with no apparent cross-talk between the sensors. These results are consistent with adaptive biasing force analysis of K+ permeation using a model selectivity filter in wild-type and mutated channels. The underlying free-energy profiles confirm that either a doubly or a singly charged pHo sensor is sufficient to abolish ion flow. Atomic detail of the associated mechanism reveals that, rather than a collapse of the pore, as proposed for other K2P channels gated at the selectivity filter, an increased height of the energetic barriers for ion translocation accounts for channel blockade at acid pHo. Our data, therefore, strongly suggest that a cycle of protonation/deprotonation of pHo-sensing arginine 224 side chain gates the TASK-2 channel by electrostatically tuning the conformational stability of its selectivity filter
