Application of artificial neural networks in assigned leadership and academic success in medical graduates.

OBJECTIVE: To apply an artificial neural networks analysis (ANN) model to identify variables that predict assigned leadership and academic success in graduates of six generations of medical school. METHOD: Analytical, retrospective, comparative study. A total of 1434 graduates participated. A questionnaire was sent to them by e-mail including a voluntary participation consent. A multivariate statistical analysis using multi-layer perceptron ANN, decision trees and driver analysis was performed. RESULTS: The ANN identified seven independent variables that predicted professional success and eight for leadership in medical graduates. The decision trees identified significant differences in the variables professional performance (p = 0.000), age (p = 0.005) and continuing education activities (p = 0.034) related to professional success, and for leadership the variables gender (p = 0.000), high school grades (p = 0.042), performing clinical practice during the social service year (p = 0.002) and continuing education activities (p = 0.011). CONCLUSIONS: The ANN identified the main independent predictor variables of professional success and leadership of the graduates. This study opens up two new lines of research little studied with the techniques of in the area of medicine.

Mexicans vs Central Americans: Violented Migrants Crossing Mexico.

INTRODUCTION: The World Health Organization considers that migrants who pass through the Mexico-US walkway suffer high levels of violence, compared to other regions of the world, mainly women. This study aims to identify the factors associated with the types of violence suffered by migrants in transit through Mexico to the USA. DESIGN: A cross-sectional, exploratory, retrospective, and observational study was conducted. A questionnaire of 46 variables was applied, divided into four sections: sociodemographic background, leaving the home, transit, and stay at the border. Questions about different types of direct violence were included. The survey was applied to 612 Mexican and Central American migrants who were in the Chaparral customs office and in five shelters in Tijuana City, on the U.S.-Mexico border. The results were analyzed using descriptive techniques and multivariate analysis of main and inferential components, using the statistical program R. RESULTS: The higher vulnerability of Central American migrants compared to Mexicans was documented, specially of women that proportionally were the most negatively affected victims including all types of violence, making it evident that one of each four was violented sexually and among them, only 50% asked for medical assistance. The multivariate analysis determined that the duration of the trip, and the type of transport can generate greater violence. CONCLUSIONS: The results highlight the greater vulnerability of Central American migrants in their transit through Mexico, mainly women and, likewise, the lack of effective public policies that guarantee the protection of the health, safety, and human rights of migrants.

Cognitive dysfunction, diabetes mellitus 2 and arterial hypertension: Sequelae up to one year of COVID-19.

BACKGROUND: Covid symptoms reflect its multisystem nature, in addition to its positive relationship between the severity of the condition and the severity of the long COVID. OBJECTIVE: To identify the factors associated with the prevalence of SEQUELAE DUE TO COVID-19 one year after their hospital discharge due to severe pneumonia. METHOD: Longitudinal, analytical, prospective and comparative study. 71 covid-19 pneumonia survivors were followed. Two telephone interviews were conducted to each patient; the first at 5 months of discharge and the second at 12 months from the mentioned date. We included questions of 40 symptoms, in addition to the questioning of diabetes mellitus and/or systemic hypertension with a mentioned onset during the hospitalization or after hospital discharge due to COVID-19. RESULTS: Of the 37 patients without complications and without comorbidities prior to hospitalization, 11 (29.7%) developed arterial hypertension during or after discharge and 17 (45.9%) developed diabetes mellitus before five months. Short-term memory loss was an upward sequel in the two measurements, 24.3% and 41.9% respectively. CONCLUSIONS: Type 2 diabetes mellitus and high blood pressure detected at five months was temporary and reversed in many cases at twelve months. It will be important to deepen the study of brain damage and cognitive dysfunction, characterized by memory loss.

Patient dissatisfaction associated with physician-patient linguistic discordance in California clinics: an analytical cross-sectional study.

BACKGROUND: Patient satisfaction is considered as a product of two psychological processes, a cognitive one, including expectations and perceptions, and an emotional one resulting from the congruence between expectation and subjective perception of the user. The objective was to identify the factors associated with the level of perceived satisfaction in patients treated in 36 nonprofit health clinics that offer comprehensive health care services in four counties in the state of California, United States. METHODS: Cross-sectional analytical study in 14 clinics in four California counties. It consisted of the application of a 30-item questionnaire to determine the degree of patient satisfaction with the clinic. The factorial composition of the quality of care and clinic quality components was analyzed and two factors with an Eigen value greater than 1 were obtained. RESULTS: A total of 846 responses were registered. Factor analysis identified two underlying dimensions: Physician Attitude and Empathy. It was found that the discordance in language between the physician and the patient generates a difference in the perception of satisfaction. Patients who prefer to speak English have better satisfaction than those who speak Spanish. Spanish speakers who do not have interpreter have lower satisfaction than those who do (p < 0,01). CONCLUSIONS: The most important sociodemographic cofactor was language. Satisfaction decreased in Spanish-speaking patients who were not proficient in the use of English since they expressed fewer comments and doubts.

Characteristics among six generations of medicine graduates.

BACKGROUND: Medical graduates follow-up programs allow the improvement of the curriculum of the Medicine career. Through identifying opportunity areas and strengthening points, institutions become increasingly competitive. OBJECTIVE: Identify the socio-demographic, formative, labor insertion and satisfaction characteristics among six generations of graduates of the Medical School of the Faculty of Medicine of the National Autonomous University of Mexico (2004-2009). METHOD: It is a descriptive, cross-sectional, retrospective, comparative study integrating the answers of mailed electronic questionnaires to 5295 graduates who concluded studies between 2004 and 2009. Descriptive and inferential techniques were used for analysis. RESULTS: An upward trend in the number of years to conclude the career was identified and an increase in failed assignments in the last three generations. Noticeable was also that, as time went by, the incorporation of physicians into the labor market was slower. Although the percentage of general unemployment was very low (2.9%). CONCLUSIONS: There are no major changes in the characteristics of the Medicine graduates. Although it is necessary to identify the reason for the increased in failed assignments which affects the length of completion. Further improvement in Research and Social Medicine programs are to be considered.

ANTECEDENTES: Los programas de seguimiento de egresados permiten mejorar los programas y el currículo de la carrera de Medicina, identificando las áreas de oportunidad y haciendo más competitivas a las instituciones educativas. OBJETIVO: Identificar las características sociodemográficas, formativas, de inserción laboral y de satisfacción, en seis generaciones de egresados de la carrera de Medicina de la Universidad Nacional Autónoma de México (2004-2009). MÉTODO: Estudio descriptivo, transversal, retrospectivo y comparativo, con 5295 egresados de la carrera de Medicina que concluyeron entre 2004 y 2009. Se envió un cuestionario por correo electrónico a cada uno de los egresados y se analizaron los resultados mediante técnicas descriptivas e inferenciales. RESULTADOS: Se observó un incremento en el número de años para concluir la carrera y un aumento en el número de materias reprobadas en las últimas tres generaciones. Además, hubo mayor lentitud en la inserción laboral en el mismo periodo, aunque el porcentaje de desempleo general fue muy bajo (2.9%). CONCLUSIONES: No hay cambios en la caracterización de los egresados respecto a generaciones anteriores; no obstante, será fundamental identificar las causas del incremento en el número de materias reprobadas que está afectando la eficiencia terminal, además de mejorar los programas de investigación epidemiológica y socio-médica.
