RESUMO
BACKGROUND: The follow-up of health sciences graduates is relevant due to the commitment of universities to train professionals who contribute to solve the country's health problems. The National Autonomous University of Mexico (UNAM) has health sciences graduates who join the workforce every year. OBJECTIVE: To identify the perception of health sciences graduates regarding the curriculum and their incorporation into the labor market from 1994 to 2015, and compare it according to the degree program and campus. MATERIAL AND METHODS: Observational, cross-sectional, comparative, quantitative study. The sample of 26,866 graduates was obtained from information of three decades of the institutional questionnaire for graduates applied by the General Directorate of Planning of the UNAM. RESULTS: Most graduates were females (68.4%), with admission to the degree course at between 19 and 20 years of age (65.4%). At least 47% had a job; incorporation into the labor market depended on not having an income, a higher grade point average, not having presented extraordinary exams, or failed subjects, among others. CONCLUSIONS: Adequate job insertion is associated with starting the degree course at age 18, having financial support, having an average of 8.1 or higher and perceiving low academic and teaching training.
ANTECEDENTES: El seguimiento de egresados en ciencias de la salud es de relevancia debido al compromiso de las universidades de formar profesionales que contribuyan a resolver los problemas de salud del país. La Universidad Nacional Autónoma de Mexico (UNAM) cuenta con egresados en ciencias de la salud que cada año se incorporan al campo laboral. OBJETIVO: Identificar la percepción de los egresados de ciencias de la salud de 1994 a 2015 respecto su formación académica y su incorporación laboral, y compararla según licenciatura y plantel. MATERIAL Y MÉTODOS: Estudio observacional, transversal, comparativo y cuantitativo. La muestra de 26 866 graduados se obtuvo de la información de tres décadas del cuestionario institucional para egresados de la Dirección General de Planeación de la UNAM. RESULTADOS: La mayoría de los egresados fue del sexo femenino (68.4 %), con ingreso a la licenciatura entre los 19 y 20 años (65.4 %). Al menos 47 % trabajaba; la incorporación laboral dependió de no contar con ingresos, mayor promedio, no haber presentado exámenes extraordinarios ni recursado materias, entre otros.

Introduction: Although a major goal of preoperative evaluation is to identify risk factors and improve postoperative outcomes, current clinical guidelines in Mexico indicate that preoperative spirometry should only be performed on patients with pulmonary disease. The aim of this study was to compare the incidence of postoperative complications (POC), mortality, and risk factors among adults who did or did not undergo preoperative spirometry, based on their Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) risk level. Material and methods: An observational, retrospective and comparative study design was used to identify 2059 patients from the General Hospital of Mexico who had an ARISCAT assessment during 2013-2017. Patients were classified in two groups: ARISCAT with spirometry (n = 1306) and ARISCAT without spirometry (n = 753). Chi-square, Fisher's exact test and the Student's t-tests were used to compare groups. Logistic regression was used to identify factors associated with an increased risk of POC and mortality. Results: In the ARISCAT with spirometry group, 11% of patients had POC, compared with 48% of patients in the ARISCAT without spirometry group. High-risk ARISCAT patients who did not receive spirometry had higher mortality (18%), than those who underwent spirometry (0.4%). Logistic regression results indicate that not performing preoperative spirometry increases the probability of POC and mortality. Conclusions: Our findings suggest that the combined use of preoperative spirometry and ARISCAT is associated with reduced POC and mortality. Future clinical guidelines should recommend the use of preoperative spirometry for patients with a moderate or high ARISCAT level in Mexico.
Introducción: La evaluación preoperatoria se centra en identificar los factores de riesgo y mejorar los resultados posoperatorios; las guías clínicas actuales en México indican la espirometría preoperatoria solo en pacientes con enfermedad pulmonar. El objetivo fue comparar la incidencia de complicaciones posoperatorias (CPO), la mortalidad y los factores de riesgo en pacientes clasificados por su nivel de riesgo de la escala de riesgo respiratorio en pacientes quirúrgicos de Cataluña (ARISCAT) sometidos o no a una espirometría preoperatoria. Material y métodos: Estudio observacional, retrospectivo y comparativo. Se clasificaron 2.059 pacientes del Hospital General de México durante 2013 a 2017; en dos grupos: ARISCAT con espirometría (n = 1.306) y ARISCAT sin espirometría (n = 753). Se aplicaron pruebas de X2, f de Fisher y t de Student para comparar los grupos y análisis de regresión logística para identificar los factores asociados a mayor riesgo de CPO y mortalidad. Resultados: Las CPO en el grupo ARISCAT con espirometría se presentaron en 11% de los pacientes, en comparación con el grupo ARISCAT sin espirometría (48%). Los pacientes ARISCAT sin espirometría de alto riesgo tuvieron una mortalidad más elevada (18%), en comparación con los pacientes que sí la realizaron (0.4%). Los resultados de la regresión logística indican que no realizar la espirometría preoperatoria incrementa la probabilidad de CPO y mortalidad. Conclusiones: Nuestros hallazgos sugieren que el uso combinado de espirometría preoperatoria y ARISCAT se asocia con menores CPO y mortalidad. Las guías clínicas futuras deberán recomendar el uso de la espirometría preoperatoria para pacientes con un nivel moderado o alto de ARISCAT en México.
RESUMO
OBJETIVO: Comparar el control glucémico entre pacientes con diabetes mellitus tipo 2 prepandemia vs pandemia de Covid-19 que acudieron a unidades de salud de primer nivel de atención de la Ciudad de México. Material y métodos. Se analizaron los registros de 23 912 pacientes con diabetes; 78.7% fueron del grupo prepandemia (2016 a 2020) y 21.3% del grupo pandemia (marzo 2020 a julio 2021). Se calcularon medidas de tendencia central y de dispersión, pruebas t de Student y se ajustó un modelo de regresión logística múltiple. RESULTADOS: La mayoría de los pacientes con diabetes fueron mujeres (66.6 y 62.6%) con edad promedio de 59 y 58 años, respectivamente, y con hemoglobina glucosilada (HbA1) final de 7.7 vs el grupo pandemia (8.0). Las variables asociadas con el descontrol glucémico incluyeron periodo, nivel de HbA1, sobrepeso, obesidad, antecedente de padres con diabetes, número de medicamentos y tipo de insulina. CONCLUSIONES: La mayoría de los pacientes con diabetes en ambos grupos tuvieron descontrol glucémico. Los pacientes del grupo pandemia tuvieron mayor descontrol glucémico de HbA1 comparados con los del grupo prepandemia. Después de recibir atención médica en ambos grupos, los pacientes mejoraron su control glucémico.
RESUMO
Innovative technologies such as the metaverse and chat GPT-4 (based on artificial intelligence) are present in the daily discourse of society; recently, they have been introduced into medical practice and are bringing about important changes. In the case of the metaverse ("beyond the universe"), various medical schools and departments around the world are beginning to use it as an innovative strategy for teaching subjects such as anatomy, histology, ophthalmology, and simulation in parallel (virtual) worlds for learning and supervision of surgeries, as well as for other applications in medical education and in the doctor-patient relationship. Although it should be regarded as an area of opportunity for the transformation of medicine, it is important to consider the various limitations and risks of the metaverse in medical practice, student training, and physicians' relationship with the health problems they have to deal with in their practice.

INTRODUCTION: Performance and selection rate of non-newly graduated physicians in a medical residency admission test as an indicator for the need of continuing education. METHODS: A database comprising 153 654 physicians who took a residency admission test in the period 2014-2018 was analysed. Performance and selection rates were assessed in relation to year of graduation and performance in medical school. RESULTS: The whole sample scored at a mean of 62.3 (SD ±8.9; range 1.11-91.11). Examinees who took the test in their year of graduation performed better (66.10) than those who took the test after their year of graduation (61.84); p<0.001.Selection rates differed accordingly; 33.9% for newly graduated physicians compared with 24.8% in those who took the test at least 1 year after graduation; p<0.001. An association between selection test performance and medical school grades was established using Pearson's correlation: r=0.40 for newly graduated physicians and r=0.30 for non-newly graduated physicians. There were statistically significant differences in selection rates for every ranking group of grades in medical school based on the χ2 test (p<0.001). The selection rates are decreased years after graduation even for candidates with high grades in medical school. DISCUSSION: There is an association between performance in a medical residency admission test and academic variables of the candidates: medical school grades and time elapsed from graduation to test taking. The evidence of decrease in retention of medical knowledge since graduation highlights the pertinence of continuing education interventions.

RESUMO
Visualizing two variables in the fluid flow requires a complex optical system to fulfill such a purpose. Furthermore, in these applications, measuring the temperature fields of the fluid is sometimes necessary. In this work, we use a color digital camera to record in one snapshot shadowgraph and two direction sensitivity Schlieren images. Furthermore, the Schlieren images obtained are used to measure temperature fields. The optical system, as main components, employs an rgb Light Emitting Diode (LED), two knife edges represented by shortpass and longpass ultra-thin filters, and a color digital camera. The results of this study show that shadowgraph images are contaminated with the crosstalk effect, and correction against it was applied. On the other hand, the reached resolution of the optical system to measure temperature values is approximately one degree.

AIM: Combining preoperative spirometry with the Assess Respiratory Risk in Surgical Patients in Catalunia (ARISCAT) risk scale can reduce post-operative complications and improve patient survival. This study aimed to assess the cost-effectiveness of performing spirometry or not in conjunction with the ARISCAT scale, to reduce post-operative complications and improve survival among adult patients undergoing elective surgery in Mexico. METHODS: A cost-effectiveness analysis (CEA) was performed to compare the specific cost and health outcomes associated with the combined use of the ARISCAT scale and preoperative spirometry (Group 1), and the use of the ARISCAT scale without preoperative spirometry (Group 2). The health outcomes evaluated were post-operative complications and survival. The perspective was from the health care provider (Hospital General de México) and direct medical costs were reported in 2019 US dollars. A decision tree with a time horizon of eight months was used for each health outcome and ARISCAT risk level. RESULTS: The combined use of the ARISCAT scale and spirometry is more cost-effective for reducing post-operative complications in the low and moderate-risk levels and is cost-saving in the high-risk level, than use of the ARISCAT scale without spirometry. To improve patient survival, ARISCAT and spirometry are also more cost-effective at the moderate risk level, and cost-saving for high-risk patients, than using the ARISCAT scale alone. CONCLUSIONS: The use of preoperative spirometry among patients with a high ARISCAT risk level was cost-saving, reduced post-operative complications, and improved survival. Our findings indicate an urgent need to implement spirometry as part of preoperative care in Mexico, which is already the standard of care in other countries.

BACKGROUND: A large portion of prescribing errors can be attributed to deficiencies in medication knowledge. These errors are preventable and most often occur at the time of prescription. Antimicrobials are the drug class most common incorrectly prescribed. OBJECTIVE: To characterize the relationship between clinical competence and antibiotic prescription errors. We also investigated the frequency and severity of antibiotic prescription errors to identify items and attributes of clinical competence which are correlated with the antibiotic prescription error ratio. METHOD: A cross-sectional study was applied to assess clinical competence of junior medical residents in two reference academic hospitals and a regional hospital in Mexico City. It was conducted during February 2019. We used an infectious disease Objective Structured Clinical Examination (OSCE) to assess clinical competence and a measure of frequency, and severity of antibiotic prescription errors. RESULTS: The number of eligible participants was ~ 255 (hospital meeting attendance), and the number of residents in this study were 51 (~ 20%), 31 were female (60.8%). The mean OSCE score was 0.692 ± 0.073. The inter-item (Cronbach's alpha = 0.927) and inter-station internal consistency was adequate (Cronbach's alpha = 0.774). The G coefficient in generalizability theory analysis was 0.84. The antibiotic prescription error ratio was 45.1% ± 7%. The most frequent category of severity of antibiotic prescription errors was category E (errors that may contribute to or result in temporary harm to the patient and require intervention), 235 (65.2%). We observed a negative and significant correlation between clinical competence and antibiotic prescription errors (r = -0.33, p < 0.05, CI95% -0.57 to -0.07), which remained significant after controlling for the effect of gender and time since graduation from medical school (r = -0.39, p < 0.01, CI95% -0.625 to -0.118). Using exploratory factor analysis we identified two factors, which explained 69% of the variance in clinical competence, factor 1 evaluated socio-clinical skills and factor 2 evaluated diagnostic-therapeutic skills. Factor 2 was correlated with antibiotic prescription error ratio (r = -0.536, p < 0.001). CONCLUSIONS: We observed a negative correlation between clinical competence and antibiotic prescription error ratio in graduated physicians who have been accepted in a medical specialty. The therapeutic plan, which is a component of the clinical competence score, and the prescription skills had a negative correlation with antibiotic prescription errors. The most frequent errors in antibiotic prescriptions would require a second intervention.

In this work, we present a panoramic digital holographic system for the first time capable of obtaining 3D information of a quasi-cylindrical object by using a conical mirror. The proposed panoramic digital holographic system is able to scan the entire surface of the object to determine the amplitude and phase simultaneously. This paper demonstrates the feasibility of analyzing quasi-cylindrical objects in a short time (0.5 s) with a single camera and a minimum number of optical components. In addition, it can be applied to determine not only topographic measurement of the cylindrical surface but also measurements of radial deformations. Experimental results are presented at different magnifications, thus illustrating its capabilities and versatility.

BACKGROUND: The choice of medical specialty is related to multiple factors, students' values, and specialty perceptions. Research in this area is needed in low- and middle-income countries, where the alignment of specialty training with national healthcare needs has a complex local interdependency. The study aimed to identify factors that influence specialty choice among medical students. METHODS: Senior students at the National Autonomous University of Mexico (UNAM) Faculty of Medicine answered a questionnaire covering demographics, personal experiences, vocational features, and other factors related to specialty choice. Chi-square tests and factor analyses were performed. RESULTS: The questionnaire was applied to 714 fifth-year students, and 697 provided complete responses (response rate 81%). The instrument Cronbach's alpha was 0.8. The mean age was 24 ± 1 years; 65% were women. Eighty percent of the students wanted to specialize, and 60% had participated in congresses related to the specialty of interest. Only 5% wanted to remain as general practitioners. The majority (80%) wanted to enter a core specialty: internal medicine (29%), general surgery (24%), pediatrics (11%), gynecology and obstetrics (11%) and family medicine (4%). The relevant variables for specialty choice were grouped in three dimensions: personal values that develop and change during undergraduate training, career needs to be satisfied, and perception of specialty characteristics. CONCLUSIONS: Specialty choice of medical students in a middle-income country public university is influenced by the undergraduate experience, the desire to study a subspecialty and other factors (including having skills related to the specialty and type of patients).

Background: Medical schools and healthcare institutions need leaders with formal training in education, in order to provide quality medical teaching. An answer to this need lies in the graduate programs of health professions education. Many programs exist, but there is a dearth of publications about their educational processes and experiences. The purpose of this study was to explore the teaching and learning experiences of students, teachers, and graduates of the Master in Health Professions Education (MHPE) program at the National Autonomous University of Mexico (UNAM). Methods: A qualitative approach was used with focus group discussions with students, graduates, and teachers, to explore their opinions, feelings, and experiences about the program. Purposeful sampling of participants was done. Focus group guides were developed for the different study groups; testimonies were codified and categorized with axial coding and a constant comparison method. Results: Testimonies from 19 participants in three focus groups were obtained (five graduates, seven current students, and seven teachers). The data were grouped in seven thematic categories: expectations, feedback of research projects, the tutorial process, teaching strategies, usefulness of what was learned, professional development, and assessment. Positive elements of the program were identified as well as areas in need of improvement. Discussion: The MHPE program at UNAM has been a positive experience for students and mostly fulfilled their expectations, they learned the basic theories and practical aspects of teaching, learning, and assessment in the health professions. Some areas need improvement, such as tutor performance and timely feedback to the students. Graduates think the competencies acquired in the program are useful for their professional practice. This information will be used to improve the program. There is a need to meet international standards in MHPE programs.

It is necessary for the community of medical educators to be acquainted with learning analytics, in order to be able to integrate it to our context in an efficacious and timely manner.

BACKGROUND: Clinical reasoning is an essential skill in physicians, required to address the challenges of accurate patient diagnoses. The goal of the study was to compare the diagnostic accuracy in Family Medicine residents, with and without the use of a clinical decision support tool (DXplain http://www.mghlcs.org/projects/dxplain). METHODS: A total of 87 first-year Family Medicine residents, training at the National Autonomous University of Mexico (UNAM) Postgraduate Studies Division in Mexico City, participated voluntarily in the study. They were randomized to a control group and an intervention group that used DXplain. Both groups solved 30 clinical diagnosis cases (internal medicine, pediatrics, gynecology and emergency medicine) in a multiple-choice question test that had validity evidence. RESULTS: The percent-correct score in the Diagnosis Test in the control group (44 residents) was 74.1±9.4 (mean±standard deviation) whereas the DXplain intervention group (43 residents) had a score of 82.4±8.5 (p<0.001). There were significant differences in the four knowledge content areas of the test. CONCLUSIONS: Family Medicine residents have appropriate diagnostic accuracy that can improve with the use of DXplain. This could help decrease diagnostic errors, improve patient safety and the quality of medical practice. The use of clinical decision support systems could be useful in educational interventions and medical practice.

In order to recover the holographic object information, a method based on the recording of two digital holograms, not only at different planes but also in a slightly off-axis scheme, is presented. By introducing a π-phase shift in the reference wave, the zero-order diffracted term and the twin image are removed in the frequency domain during the processing of the recorded holograms. We show that the zero-order elimination by the phase-shifted holograms is better than working with weak-order beam and average intensity removal methods. For recording experimentally two π-shifted holograms at different planes slightly off-axis, a single cube beam splitter is used. Computer simulations and experimental results, carried out to validate our proposal, show a high accuracy of π/14 that can be comparable with phase-shifting digital holography. For high fringe spacing, our proposal could be applied in electron holography, avoiding high voltage in a biprism.
