    The objective is to know if students are located in the digital divide, have digital skills for cyber-coexistence and participate in cyberbullying. Quantitative research, 637 high school students from the State of Mexico participated. An instrument that measures the study variables was applied. It is concluded that the students present a digital divide in the second level, participate in cyberbullying and are not digital citizens.El objetivo es conocer sí los estudiantes se encuentran situados en brecha digital, cuentan con habilidades digitales para la ciber-convivencia y participan en ciberbullying. Investigación cuantitativa, participaron 637 alumnos  (bachillerato). Se aplicó un instrumento que mide las variables del estudio. Se identificó que el alumnado presenta brecha digital, participa en ciberbullying y no son ciudadanos digitales

    Las habilidades, pensamientos y acciones respecto al uso de Internet, quelogran que una persona tenga una participación activa dentro de las sociedadesconstruidas en el mundo de las Tecnologías de la Información y la Comunicación daorigen a la ciudadanía digital, necesaria para alcanzar una convivencia armónica. Elobjetivo del estudio es conocer la incidencia de las conductas en Ciudadanía Digital,identificando las diferencias significativas entre hombres y mujeres. Se realizó unainvestigación cuantitativa, descriptivo y diseño transversal, con 350 estudiantesmexiquenses de una escuela pública. Para medir la variable de estudio se utilizóla Escala de Ciudadanía Digital (α=.88). Los resultados señalan que los jóvenes notienen habilidades básicas para comprender y evaluar los contenidos e informaciónmediática para tomar decisiones, así como tampoco tienen participación política nisocial “en línea”, los resultados también indican que no hay un sexo que predomineen ciudadanía digital

    Perspectiva universitaria Una visión multidisciplinaria sobre la ética y la realidad

    Get PDF
    La presente obra muestra a la población lectora, desde una perspectiva universitaria multidisciplinaria, un conjunto de siete investigaciones de corte teórico, que motivan la reflexión sobre las realidades sociales, donde las diferentes éticas analizadas aportan elementos teóricos y posibles estrategias para acompañar en la solución de los conflictos que encara la vida actual en el planeta.Ante los retos que enfrenta la humanidad, algunas veces consecuencia de comportamientos acumulados de baja prosocialidad y civilidad, donde el egoísmo, los abusos y la irresponsabilidad han cobrado protagonismo, son las instituciones educativas, y especialmente las universidades quienes tienen el compromiso de preparar y actualizar profesionistas cuyo perfil de egreso sea capaz de atender las necesidades apremiantes demandas por la colectividad, mismas que muchas veces no generan el reconocimiento público y, por lo tanto, no llegan a provocar una respuesta comprometida desde las políticas públicas, como puede ser el trato en los servicios a las personas más vulneradas, otras veces desde el abuso de la desinformación que termina por dar fuerza al rumor y con ello, desencadenar problemas de pánico, violencia, o incapacidad de atención, como ha sido el caso de la pandemia por el virus SARS CoV2, analizado ampliamente en este libro

    Performance of visual inspection of the cervix with acetic acid (VIA) for triage of HPV screen-positive women: results from the ESTAMPA study

    Q1Q1Pacientes con Virus del Papiloma Humano (VPH)VIA is recommended for triage of HPV-positive women attending cervical screening. In the multicentric ESTAMPA study, VIA performance for detection of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) among HPV-positive women was evaluated. Women aged 30-64 years were screened with HPV testing and cytology and referred to colposcopy if either test was positive. At colposcopy visit, study-trained midwives/nurses/GPs performed VIA ahead of colposcopy. VIA was considered positive if acetowhite lesions were observed in or close to the transformation zone. Ablative treatment eligibility was assessed for VIA positives. Performance indicators were estimated. Three thousand one hundred and forty-two HPV-positive women were included. Sensitivity for CIN3+ was 85.9% (95% CI 81.2-89.5) among women <50 years and, although not significant, slightly lower in women 50+ (78.0%, 95% CI 65.9-86.6). Overall specificity was 58.6% (95% CI 56.7-60.5) and was significantly higher among women 50+ (70.3%, 95% CI 66.8-73.5) compared to women <50 (54.3%, 95% CI 52.1-56.5). VIA positivity was lower among women 50+ (35.2%, 95% CI 31.9-38.6) compared to women <50 (53.2, 95% CI 51.1-55.2). Overall eligibility for ablative treatment was 74.5% and did not differ by age. VIA sensitivity, specificity, and positivity, and ablative treatment eligibility varied highly by provider (ranges: 25%-95.4%, 44.9%-94.4%, 8.2%-65.3%, 0%-98.7%, respectively). VIA sensitivity for cervical precancer detection among HPV-positive women performed by trained providers was high with an important reduction in referral rates. However, scaling-up HPV screening triaged by VIA will be challenging due to the high variability of VIA performance and providers' need for training and supervision.https://orcid.org/0000-0001-7187-9946Revista Internacional - IndexadaA1N

    Multicentric study of cervical cancer screening with human papillomavirus testing and assessment of triage methods in Latin America : the ESTAMPA screening study protocol

    Q1Q1Introduction Human papillomavirus (HPV) testing is replacing cytology in primary screening. Its limited specificity demands using a second (triage) test to better identify women at high-risk of cervical disease. Cytology represents the immediate triage but its low sensitivity might hamper HPV testing sensitivity, particularly in low-income and middle-income countries (LMICs), where cytology performance has been suboptimal. The ESTAMPA (EStudio multicéntrico de TAMizaje y triaje de cáncer de cuello uterino con pruebas del virus del PApiloma humano; Spanish acronym) study will: (1) evaluate the performance of different triage techniques to detect cervical precancer and (2) inform on how to implement HPV-based screening programmes in LMIC. Methods and analysis Women aged 30–64 years are screened with HPV testing and Pap across 12 study centres in Latin America. Screened positives have colposcopy with biopsy and treatment of lesions. Women with no evident disease are recalled 18 months later for another HPV test; those HPV-positive undergo colposcopy with biopsy and treatment as needed. Biological specimens are collected in different visits for triage testing, which is not used for clinical management. The study outcome is histological high-grade squamous intraepithelial or worse lesions (HSIL+) under the lower anogenital squamous terminology. About 50 000 women will be screened and 500 HSIL+ cases detected (at initial and 18 months screening). Performance measures (sensitivity, specificity and predictive values) of triage techniques to detect HSIL+ will be estimated and compared with adjustment by age and study centre. Ethics and dissemination The study protocol has been approved by the Ethics Committee of the International Agency for Research on Cancer (IARC), of the Pan American Health Organisation (PAHO) and by those in each participating centre. A Data and Safety Monitoring Board (DSMB) has been established to monitor progress of the study, assure participant safety, advice on scientific conduct and analysis and suggest protocol improvements. Study findings will be published in peer-reviewed journals and presented at scientific meetings. Trial registration number NCT01881659Revista Internacional - Indexad
