Modelagem matemática dos casos autóctones de Covid-19. Município de Bayamo. Fevereiro a agosto de 2021

The Bayamo municipality accumulated 8162 autochthonous positive cases from February to August in 2021, it is the center of the epidemic in the province of COVID-19 caused by SARS-CoV-2 determined by the C-Reactive Protein test, represents the 53.2% of the total cases in that period in Granma, very different from what happened in 2020 in which the province accumulated only 185 infected people in nine months, with a rate of 22.6, the lowest in Cuba. Granma province accumulated 119 deaths in August / 2021, which represents 62.9% of all deaths since the pandemic began until August, which indicates the high incidence of the epidemic that exists at the moment. For the mathematical modeling and analysis of the autochthonous positive cases of all those that occurred during the months of February to August in 2021 in Bayamo, polynomials of degree three and four were obtained that model the behavior of the epidemic during the seven months analyzed. as well as that of the deceased during the month of August in Granma with a predictive character greater than 98% in all models.El municipio Bayamo acumuló, 8162 casos positivos autóctonos de febrero a agosto en el año 2021, es el centro de la epidemia en la provincia de COVID-19 provocada por el SARS –CoV-2 determinado por el test de Proteína C Reactiva, representa el53,2 % del total de los casos en ese periodo en Granma, muy diferente a lo ocurrido en el año 2020 en el cual la provincia acumuló solamente 185personas contagiadas en nueve meses, con una tasa de 22.6 la más baja de Cuba. La provincia Granma acumuló 119 fallecidos en agosto/2021 que representa el 62,9 % de todos los muertos desde que comenzó la pandemia hasta agosto, lo que indica la alta incidencia de la epidemia que hay en estos momentos. Para la modelación matemática y el análisis de los casos positivos autóctonos de todos los ocurridos durante los meses de febrero a agosto en el año 2021 en Bayamo se obtuvieron polinomios de grado tres y cuatro que modelan el comportamiento de la epidemia durante los siete meses analizados, así como el de los fallecidos durante el mes de agosto en Granma con un carácter predictivo mayor al 98 % en todos los modelos.O município de Bayamo acumulou 8.162 casos autóctones positivos de fevereiro a agosto de 2021, é o centro da epidemia na província de COVID-19 causada pelo SARS-CoV-2 determinado pelo teste da Proteína C Reativa, representa 53,2% de o total de casos nesse período no Granma, muito diferente do que aconteceu em 2020 em que a província acumulou apenas 185 pessoas infectadas em nove meses, com uma taxa de 22,6, a mais baixa de Cuba. A província do Granma acumulou 119 mortes em agosto / 2021, o que representa 62,9% de todas as mortes desde o início da pandemia até agosto, o que indica a alta incidência da epidemia que existe no momento.

Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

Estrategia pedagógica para el desarrollo de competencias en estadística en los profesionales de la salud

Background: there are insufficiencies in the statistical formation of the health professional that cause limitations in different tasks to be faced. Objective: to evaluate the feasibility of a pedagogical strategy of improvement for the development of statistics competencies in health professionals. Methods: a pedagogical strategy was applied that culminated with a pedagogical preexperiment in the "Efraín Benítez Popa" Medical Sciences Branch of Bayamo, during 2010- 2015. Theoretical, empirical methods, the Delphi method and the mathematical method were used: the descriptive statistics with the absolute, percent and inferential frequencies were applied the Wilcoxon test. Results: shortcomings were identified in the teachers on statistical didactics and the use of statistical packages, insufficiencies in the development of the methodological work and lack of postgraduate improvement actions, for which a pedagogical strategy was applied for the development of competences in this sense. Conclusions: the pedagogical pre-experiment applied allowed to evaluate the strategy as feasible to solve the difficulties in the preparation of the teachers on the contents of statistics and its application. Furthermore, it was considered by the experts as pertinent and with adequate methodology.Fundamento: existen insuficiencias en la formación estadística del profesional de la salud que provocan limitaciones en diferentes tareas a afrontar.Objetivo: valorar la factibilidad de una estrategia pedagógica de superación para el desarrollo de competencias en estadística en los profesionales de la salud.Métodos: se aplicó una estrategia pedagógica que culminó con un prexperimento pedagógico en la Filial de Ciencias Médicas “Efraín Benítez Popa” de Bayamo, durante 2010-2015. Se utilizaron métodos teóricos, empíricos, el método Delphi y como método matemático: la estadística descriptiva con las frecuencias absoluta, porcientos y de la inferencial se aplicó la prueba de Wilcoxon.Resultados: se identificaron insuficiencias en los docentes sobre didáctica de la estadística y el uso de paquetes estadísticos, insuficiencias en el desarrollo del trabajo metodológico y carencia de acciones de superación de posgrado, por lo cual se aplicó una estrategia pedagógica para el desarrollo de competencias en este sentido.Conclusiones: el prexperimento pedagógico aplicado permitió valorar la estrategia como factible para resolver las dificultades en la preparación de los docentes sobre los contenidos de estadística y su aplicación. Además fue considerada por los expertos como pertinente y con adecuada metodología.
