Differences in medical education before, during, and in the post-peak period of the COVID-19 pandemic-exploring senior medical students' attitudes.

BACKGROUND: The burden that COVID-19 has brought to the economy, healthcare systems, and education is unmatched. Public health and social measures were implemented to halt transmission. Thus, social gathering and in-person learning, core aspects of medical education, were interrupted. Studies have documented the detrimental impact students graduating during the pandemic have had on their confidence and skills. However, data comparing pre-pandemic, pandemic, and post-peak students still lack. This study aimed to identify senior medical students' attitudes regarding their education and compare them according to the three previously described periods. METHODS: In this cross-sectional study, the survey employed was designed based on a previous questionnaire and applied to senior medical students before graduating between January 2018 and June 2022. Answers were collected using a three-point Likert scale and Yes/No questions. Associations between variables were examined using Chi-squared, Fisher's Exact tests, and ANOVA, employing logistic regression to calculate odds ratio (OR) when appropriate. RESULTS: A total of 679 responses were analyzed. Most students (59%) were women. Up to 383, 241, and 55 senior medical students answered the survey before, during, and in the post-peak period of the COVID-19 pandemic, respectively. There was a staggering decrease in the percentage of students in the post-peak compared to the pre-pandemic period that considered certain factors such as being taught about the doctor-patient relationship (62% vs 75%), practicing teamwork (33% vs 54%), preclinical & clinical subjects (44% vs 63%), and being taught to conduct research (22% vs 32%) as "very useful" to their professional traineeship. There was a significant difference between pre-pandemic, pandemic, and post-peak students when asked if the study curriculum accomplished the goal of training a professional with integrity (89% vs 66% vs 64%, p < 0.001), respectively. In a multivariate analysis graduating during the pandemic (OR 3.92; 95% CI, 2.58-5.94) and in the post-peak period (OR 4.24; 95% CI, 2.23-8.07) were independent factors for the appreciation that the study curriculum did not meet its objective. CONCLUSIONS: The pandemic has hindered medical education. Students' appreciation of their instruction has deteriorated. Urgent interventions that halt the negative impact on training, ensure readiness for future problems and improve schooling worldwide are needed.

Modelo de desarrollo local para una zona de bogotá-colombia, relacionando la estructura ecológica principal y el proceso de expansión urbana

Dada la importancia de asumir el reto del crecimiento acelerado de las ciudades, surge la necesidad de planear estrategias de mejoramiento territorial, que contengan enfoques cruzados, capaces de interpretar la complejidad generada entre los procesos de expansión y los ecosistemas naturales. Para ello, el objetivo de este estudio fue establecer las relaciones entre la estructura ecológica principal, como componente fundamental de la ciudad de Bogotá, Colombia y la expansión urbana, como proceso de crecimiento acelerado, característico de las últimas dos décadas. Al utilizar un método con énfasis en relaciones complejas, se logró diseñar un modelo de desarrollo local, con criterios de índole multiespacial, multitemporal y multiobjetivo, que fue ajustado con la participación de las comunidades de dos barrios y con el uso de sistemas de información geográfica.

Given the importance of the challenge of the rapid growth of cities, there is a need to generate territorial improvement strategies that contain cross approaches, able to interpret the complexity generated between processes of expansion and natural ecosystems. Therefore the aim of this study was to establish the relationships between the main ecological structure, as a fundamental component of urban expansion, and the city of Bogotá - Colombia, as a process of accelerated growth characteristic of the last two decades. When employing a method with emphasis on complex relationships, the design of a model of local development was achieved, with criteria of multi-spatial, multi-temporal and multi-objective nature, adjusted with the participation of the communities in two districts and the use of geographic information systems.

Sensibilidad in vitro de hongos miceliales de aislamientos clínicos en pacientes con cáncer en el Instituto Nacional de Cancerología ESE / in vitro susceptibility of clinical isolates of filamentous fungi in patients with cancer in the Instituto Nacional de Cancerología

Introducción: la sensibilidad antifúngica in vitro en hongos filamentosos no ha tenido el mismo desarrollo que en levaduras. Se dispone de limitada información sobre la susceptibilidad en este tipo de aislamientos en Colombia. Materiales y métodos: se determinó la actividad in vitro de fluconazol, voriconazol, itraconazol, anfotericina B y caspofungina mediante el método de E-Test, de los géneros Aspergillus (36 A. fumigatus, 12 A. flavus, 9 A. niger, 6 A. terreus, 4 A. nidulans y 1 A. versicolor) e hifomicetes hialinos (9 Fusarium sp., 2 Geotrichum sp. y 2 Paecilomyces sp.), provenientes en su mayoría de lavados broncoalveolares (30%) y biopsias pulmonares (36%); 9% provenían de hemocultivos. Resultados: el perfil de resistencia general fue 28% para itraconazol, 15% para caspofungina, 14% para anfotericina B y 5% para voriconazol. En general, todos los aislamientos presentaron una sensibilidad disminuida para fluconazol e itraconazol. La mejor actividad farmacológica la presentaron voriconazol, caspofungina y anfotericina B. Fusarium sp. presentó una mayor actividad con el voriconazol. Se encontraron diferencias entre el tipo de micelio (Aspergillus vs no Aspergillus) y la susceptibilidad a voriconazol, anfotericina B y caspofungina. Conclusión: en general, los antimicóticos disponibles para el tratamiento de infecciones por miceliales muestran una sensibilidad disminuida in vitro en relación con el género y la especie identificada.

Introduction: fungal susceptibility against micelial fungi has not been developed at the same pace as susceptibility against yeasts. Scarce information is available about that kind of isolates in Colombia. Materials and methods: in vitro susceptibility against micelial isolates from patients with cancer was determined. The E-test method was used to find out susceptibility against fluconazole, voriconazole, itraconazole, amphotericin B, and caspofungin. Isolates of the genera Aspergillus (36 A. fumigatus, 12 A. flavus, 9 A. niger, 6 A. terreus, 4 A. nidulans and one A. versicolor isolate), Fusarium (n=9), Geotrichum and Paecilomyces (n=2 each one) obtained from patients with cancer were tested. These isolates were obtained from bronchoalveolar lavage (30%), pulmonary biopsies (36%) and bloodstream infections (9%). Results: The general pattern of resistance was 28% against intraconazole, 15% against caspofungin, 14% against amphotericin B, and 5% against voriconazole. In general, susceptibility against fluconazole and itraconazole showed a diminishing trend. Voriconazole, caspofungin, and amphotericin B showed the best pharmacologic potency. Fusarium sp. presented a higher activity level against voriconazole. There were differences in the susceptibility against voriconazole, anphotericin B, and caspofungin depending on the type of micelial isolate (Aspergillus vs. Non- Aspergillus). Conclusion: In general, the available antifungal treatments against mycelial fungi identified in the cancer center show diminished susceptibility.
