Evaluación de un call center de orientación clínica durante los primeros meses de pandemia COVID-19: capacidad de resolución de los llamados

Background: During sanitary emergencies such as the recent pandemic, health services can collapse. In these cases, remote orientation services such as call centers may help to debottleneck these services. Aim: To assess the demand and problem resolution of a clinical guidance telephone service during the COVID-19 pandemic. Material and Methods: The call registry between May and August 2020 of an orientation call center for COVID-19 was analyzed. The number of calls, sociodemographic features of callers, type of enquiry and given indications were described. Results: We analyzed 1,278 telephone calls, corresponding to 655 people. Sixty nine percent of queries were resolved during the call and in 31% of calls, users were referred to face-to-face evaluation. Two percent of these referrals were to an emergency service. Conclusions: The call center had a high level of resolution, favoring remote consultation and reducing face-to-face care, improving users'accessibility.

Perfil antropométrico, somatotipo y estado nutricional del taekwondoín mexicano / Anthropometric profile, somatotype and nutritional status of Mexican taekwondoin

RESUMEN: El perfil antropométrico y el somatotipo son herramientas imprescindibles para monitorizar el rendimiento morfológico del atleta de alto rendimiento. El objetivo del presente estudio es la descripción del perfil antropométrico y el somatotipo dominante de atletas mexicanos de taekwondo (TKD) de alto rendimiento. El perfil antropométrico y el somatotipo fueron determinados en 16 atletas de TKD mexicanos [8 hombres, edad media 21,5 años (19,8-23,0, IC 95%); 8 mujeres, edad media 21,9 años (19,2-24,4, IC 95%)]. Una prueba T-Student para muestras independiente fue usada para comparar las medias entre ambos sexos (Hombres vs Mujeres). La estatura (P = 0,001), los pliegues del muslo anterior (p = 0,006) y pantorrilla (p = 0,049), la circunferencia del brazo flexionado (p = 0,047), los diámetros del húmero (p = 0,011) y fémur (p = 0,012), el área total y área muscular del brazo (p = 0,001) fueron significativamente diferentes entre hombres y mujeres. Un somatotipo ecto-mesomórfico predomino tanto en hombres (2,1-3,2-4,2) como en el grupal (2,4-3,1-3,8), pero ectomorfo-mesomórfico (2,8-3,2-3,4) para las mujeres. El somatotipo del atleta de TKD mexicano predominó por una mayor linearidad relativa seguido de una magnitud musculoesquelética y una menor adiposidad relativa. Los hallazgos de este estudio aportan evidencias morfológicas para monitorizar el rendimiento físico y nutricional del atleta de TKD.

SUMMARY: Body composition, somatotype and nutritional status are essential tools for monitoring the perfor- mance of high-performance athlete. The objective of the present study was to verify the body composition, the dominant somatotype and nutritional status of high-performance taekwondo athletes of the Mexican TKD team. The anthropometric profile, somatotype and nutritional status were determined in sixteen Mexican TKD athletes [8 men, mean age 21.5 yrs. (19.8-23.0 95% CI); 8 women, mean age 21.9 yrs. (19.2-24.4 95% CI)]. An independent-samples t-test was used to compare the means between both genders (Men vs. Women). The height (p = 0.001), the anterior thigh (p = 0.006) and calf (p = 0.049) folds, the flexed arm circumference (p = 0.047), the humerus (p = 0.011) and femur (p = 0.012) diameters, the fat free mass (p = 0.020) and arm total area (p = 0.049) and arm muscle area (p = 0.001) were significantly different between men and women. The percentage of body fat and arm fat area were not significant between both genders. A normal caloric reserve, but a slightly high percentage of body fat was observed for both genders. In addition, normal and high protein reserves were identified for men and women, respectively. An ecto-mesomorphic somatotype was highlighted in both men (2.1-3.2-4.2) and in the group (2.4-3.1-3.8), but ectomorphic- mesomorphic (2.8-3.2-3.4) to women. The somatotype of the Mexican TKD athlete predominated by a greater relative linearity followed by a musculoskeletal magnitude and a lower relative adiposity. The findings of this study provide morphological evidence to monitor the physical and nutritional performance of the high-performance TKD athlete.

Ley 21331: nuevos desafíos de la Ley del reconocimiento y protección de los derechos de las personas en la atención de salud mental / Law 21331: new challenges of the law of recognition and protection of people's rights in mental health care

Since the dawn of the Republic, the question regarding the diagnosis, management and treatment of mental illnesses has been an unresolved issue to this day. Since before the time of the colony, at the time of the conquest, mental illnesses abounded, both in the Mapuche population - autochthonous indigenous - and in the Spanish. The presence in the river basins of heavy metals and minerals toxic for human consumption, as was originally the Mapocho River, whose waters were not drinkable and were only used for crops adopted from the Inca culture, were consumed by the population of the Spanish conquerors, who manifested various types of mental disorders, either due to the consumption of polluted water and the neurological damage that it caused them, the high levels of stress due to the same occupation and the isolation in which they found themselves and the diseases venereal that they carried, which they progressively transmitted to the aboriginal population. (1) On the other hand, the Mapuche population had magical-ritual treatments and methods to treat these and other diseases based on herbalism, phytotherapy and rituals (2) for the evil of melancholy (depression), anxiety disorders, panic attacks and schizophrenia. (3) Centuries later, when medicine and hard science are presented in society giving way to the scientific method, key people make their appearance within mental health studies, who made their way into the national and world panorama, and who, despite the dark past and the tortuous evolution of this branch of medicine, stand out figures who were pioneers and who gave rise to a reality that today continues in constant development and debate. Today mental health is an issue on the table, and Law 21331, promulgated on April 23, 2021 (4) is a response to changes in the perception that society currently has of the concept of disease, which is contrasted to the thinking and management that existed for years, decades and centuries ago around mental health

Desde los albores de la República, la cuestión referente al diagnóstico, manejo y tratamiento de las enfermedades mentales ha sido un tema sin resolver hasta nuestros días. Desde antes del tiempo de la colonia, en la época de la conquista, las enfermedades mentales abundaban, tanto en la población mapuche -indígena autóctona- como en la española. La presencia en las cuencas fluviales de metales pesados y minerales tóxicos para el consumo humano, como fue en su origen el río Mapocho, cuyas aguas no eran bebestibles y solo se utilizaban para los cultivos adoptados de la cultura inca, fueron consumidas por la población de los conquistadores españoles, los cuales manifestaron diversos tipos de trastornos mentales, ya fuese por el consumo de aguas contaminadas y el daño neurológico que les provocaba, los altos niveles de estrés debido a la misma ocupación y al aislamiento en el que se encontraban y las enfermedades venéreas que portaban, las cuales transmitieron progresivamente a la población aborigen. (1) Por otra parte, la población mapuche tenía tratamientos y métodos mágico-rituales para tratar estas y otras enfermedades basados en la herbolaria, la fitoterapia y los rituales (2) para el mal de la melancolía (depresión), trastornos ansiosos, crisis de pánico y la esquizofrenia.(3) Siglos más tarde, cuando la medicina y la ciencia dura se presentan en sociedad dando paso al método científico, hacen su aparición personas clave dentro de los estudios en salud mental, quienes se abrieron camino dentro del panorama nacional y mundial, y que, pese al pasado oscuro y a la evolución tortuosa de esta rama de la medicina, se destacan figuras que fueron pioneras y que dieron pie a una realidad que hoy en día continúa en constante desarrollo y debate. Hoy la salud mental es un tema sobre la mesa, y la Ley 21331, promulgada el 23 de abril del año 2021 (4) es una respuesta a los cambios en la percepción que la sociedad actualmente tiene frente al concepto de enfermedad, que se contrasta al pensamiento y manejo que durante años, décadas y siglos atrás existió en torno a la salud mental

INTRODUCTION: Before the start of the GES program in 2002, mortality was 128.2 deaths per million children under 15 years of age (RENCI). This public program managed to ensure the opportunity for diagnosis and treatment in children under 15 years of age and those less than 25 years of age who recur. Objective: To assess how GES has impacted on in-hospital mortality and lethality between1997and 2016. Methods: Retrospective case control study of 28,997 hospital discharges and 12,434 deaths analyzed using Prais-Weinstein time series between the years 1997 to 2016. They prepared contingency tables with data on: hospital discharges, age, sex and forecasts for 2001 and 2016. Fisher's p <0.05 test was used. Results: For the PreGes period an increase of 1.8% in the male crude mortality rate was observed, while for the Post Ges period an increase was observed with a breaking point at the end of 2008, with an increase of 11.04% compared to the PreGes period. An unexpected increase in the female mortality rate was observed.

Síndrome de Austrian: reporte de caso / Austrian syndrome: report of one case

Austrian syndrome is a triad characterized by pneumonia, meningitis and endocarditis, as a result of a Streptococcus pneumoniae bacteremia. We report a previously healthy 49 year-old male, who consulted at the emergency care unit with a history of one week of pleuritic pain, fever leading to an altered level of consciousness and seizures. A diagnosis of community-acquired pneumonia and meningitis was reached, isolating Streptococcus pneumoniae in the cerebrospinal fluid and blood cultures. Antibiotic treatment was started but the patient had an unsatisfactory response. During hospitalization a new heart murmur was found in the physical examination. An echocardiography was performed and a massive aortic valve insufficiency was found along with vegetations and a perforation of the same valve. The valve was replaced by a prosthetic one and the patient responded satisfactorily to the surgical and antibiotic treatment, without complications.

Impacto de la aplicación del enfoque de autorregulación del aprendizaje sobre los resultados en asignaturas de corte científico en estudiantes de medicina de la Universidad Finis Terrae / The impact of a self-directed teaching approach on academic performance of medical students

Background: Students should be encouraged to become reflexive and develop autonomous, lifelong learning habits. Therefore, teachers should focus on learning strategies which stimulate autonomous learning. Aim: To assess the impact of a self-directed teaching methodology on the academic performance of medical students in cellular biology and biochemistry. Materials and Methods: During 2013, 85 students received a traditional teaching methodology and during 2014, 85 students received a self-directed learning methodology. The grades obtained and the number of failures in the courses of cellular biology and biochemistry were compared in both groups. Results: The percentages of students approved at the end of the courses during 2013 and 2014 were 64 and 96% respectively (p < 0.01). The grades obtained by the 2014 students were also significantly higher than those obtained by 2013 students. Conclusions: This study confirms that academic performance improves with a self-directed teaching approach.

Increasing access to comprehensive care for Chagas disease: development of a patient-centered model in Colombia / Aumento del acceso a la atención integral de la enfermedad de Chagas: elaboración de un modelo centrado en el paciente en Colombia / Maior acesso à atenção integral para doença de Chagas: construção de um modelo centrado no paciente na Colômbia

ABSTRACT Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Colombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia's annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it. This represents a missed opportunity for increasing patients' healthy, productive years of life while significantly reducing the economic burden on the health care system. Key barriers are complexities and delays in the diagnosis and treatment process, lack of awareness of CD among both patients and health care professionals, and administrative barriers at the primary care level. In 2015, stakeholders from government, academia, nongovernmental organizations, and patient associations participated in a seminar in the city of Bogotá on eliminating barriers to diagnosis and treatment for CD. The seminar gave birth to a model of care for increasing patient access, including a patient road map that simplifies diagnostic and treatment processes, shifting them from specialists to primary care facilities. The patient road map was implemented in a pilot project in four endemic communities beginning in 2016, with the goal of testing and refining the model so it can be implemented nationally. This article describes key components in the development of a new, recently implemented model of care for CD in Colombia.(AU)

RESUMEN En todo el mundo, hay más de 6 millones de personas infectadas por el Trypanosoma cruzi, el agente patógeno causante de la enfermedad de Chagas. En la Región de las Américas, esta es la infección parasitaria que tiene la mayor carga en cuanto a años de vida ajustados en función de la discapacidad. En Colombia, 437 000 personas están infectadas por el T. cruzi; de ese total, 131 000 sufren de miocardiopatía. En ese país, el costo anual de tratar a los pacientes que tienen la enfermedad de Chagas se ubica en US$ 175 016 000. A pesar de que un tratamiento etiológico oportuno puede retrasar o prevenir significativamente la aparición de una miocardiopatía —a un costo de apenas US$ 30 por paciente— menos de 1% de las personas con enfermedad de Chagas en Colombia y otros países lo reciben. Esto implica que se pierde la oportunidad de incrementar el número de años de vida saludables y productivos de los pacientes y, al mismo tiempo, reducir significativamente la carga económica que soporta el sistema de atención de salud. Los obstáculos clave son la complejidad y las demoras en los procesos de diagnóstico y tratamiento, la falta de conocimiento sobre la enfermedad de Chagas por parte de los pacientes y de los profesionales de la salud, y las barreras administrativas que existen a nivel de la atención primaria. En el 2015, representantes del gobierno, la comunidad académica, organizaciones no gubernamentales y asociaciones de pacientes participaron en un seminario en Bogotá sobre la eliminación de las barreras al diagnóstico y el tratamiento de la enfermedad de Chagas. En este seminario se elaboró un modelo de atención para aumentar el acceso de los pacientes, incluida una hoja de ruta centrada en el paciente que simplifica los procesos de diagnóstico y tratamiento al trasladarlos de los especialistas a los establecimientos de atención primaria. La hoja de ruta centrada en el paciente se aplicó a principios del 2016 como parte de un proyecto piloto que se puso en marcha en cuatro comunidades endémicas con el objetivo de poner a prueba y perfeccionar el modelo para luego poder aplicarlo en todo el país. En este artículo se describen los componentes clave que se usaron para crear un modelo de atención de la enfermedad de Chagas puesto en marcha recientemente en Colombia.(AU)

RESUMO Em todo o mundo, cerca de 6 milhões de pessoas são infectadas pelo Trypanosoma cruzi, o patógeno causador da doença de Chagas. Nas Américas, esta infecção parasitária é responsável pela maior carga de anos de vida perdidos ajustados por incapacidade. Na Colômbia, estima-se que 437 mil pessoas são infectadas pelo T. cruzi, das quais 131 mil têm miocardiopatia. O custo anual para tratar os pacientes com doença de Chagas em estágio avançado chega a US$ 175.016.000. Embora o tratamento oportuno mirando o agente etiológico possa postergar significativamente, ou prevenir, a ocorrência de miocardiopatia, ao custo de apenas US$ 30 por paciente, menos de 1% dos portadores da doença de Chagas é tratado na Colômbia e em outros lugares. Representa uma perda de oportunidade de prolongar os anos de vida saudável e produtiva dos pacientes e de reduzir consideravelmente o ônus econômico ao sistema de saúde. Os principais entraves são a complexidade e a demora do processo de diagnóstico e tratamento, a falta de conhecimento sobre a doença por parte dos pacientes e dos profissionais da saúde e os obstáculos administrativos ao nível da atenção primária. Em 2015, interessados diretos de setores do governo, comunidade acadêmica, organizações não governamentais e associações de pacientes participaram de um seminário realizado na cidade de Bogotá em que discutiram como eliminar as barreiras ao diagnóstico e ao tratamento da doença de Chagas. Deste seminário nasceu um modelo para aumentar o acesso dos pacientes à atenção à saúde, com a preparação de um guia simplificado para o diagnóstico e o tratamento e a transição do atendimento dos serviços especializados aos serviços de atenção primária. Como parte de um projeto-piloto, a partir de 2016, o guia do paciente foi implantado em quatro comunidades endêmicas com o propósito de testar e aprimorar o modelo para que possa ser implantado em todo o país. O presente artigo descreve os principais componentes deste modelo de atenção para a doença de Chagas recém-implantado na Colômbia.(AU)

Evaluación de un programa de perfeccionamiento docente implementado en la Facultad de Medicina de la Universidad Finis Terrae / Evaluation of a teaching training program implemented in a faculty of medicine

Background: Since 2010, the Faculty of Medicine at Finis Terrae University implemented a training program aiming to train health professionals in effective educational practices. Aim: To evaluate the effect of training in teachers who are in charge of planning courses, conducting classes and learning assessment. Material and Methods: Quality of planning, lecture performance and academic performance of students were evaluated in 55 teachers prior and after attending the training course on teaching methodologies and in 47 teachers not attending the course. Results: The percentage of trained teachers complying with the aforementioned indicators was significantly higher than those without training (p < 0.01). There were significant differences in favor of the group of teachers who attended and passed the Diploma. Trained teachers had significantly higher students’ approval rate. (Odds ratio 4.5, p < 0.01). Conclusions: The teaching Diploma in Health Sciences improved the planning, teaching and academic performance of teachers.

Diplomado de salud y humanización: el valor de la reflexión y el aprendizaje presencial / Health and humanization Diploma: the value of reflection and face to face learning

Background: In a rapidly changing culture like ours, with emphasis on productivity, there is a strong need to find the meaning of health care work using learning instances that privilege reflection and face to face contact with others. The Diploma in Health and Humanization (DSH), was developed as an interdisciplinary space for training on issues related to humanization. Aim: To analyze the experience of DSH aiming to identify the elements that students considered key factors for the success of the program. Material and Methods: We conducted a focus group with DSH graduates, identifying factors associated with satisfaction. Transcripts were coded and analyzed by two independent reviewers. Results: DSH graduates valued a safe space, personal interaction, dialogue and respect as learning tools of the DSH. They also appreciates the opportunity to have emotional interactions among students and between them and the teacher as well as the opportunity to share personal stories and their own search for meaning. Discussion: DSH is a learning experience in which their graduates value the ability to think about their vocation and the affective interaction with peers and teachers. We hope to contribute to the development of face to face courses in the area of humanization. Face to face methodology is an excellent teaching technique for contents related to the meaning of work, and more specifically, to a group of learners that require affective communication and a personal connection of their work with their own values and beliefs.

Efecto del enfoque de autorregulación del aprendizaje en la enseñanza de conceptos científicos en estudiantes universitarios en ciencias de la salud / The efficiency of self-regulated learning in the teaching of scientific concepts to health sciences students

Background: In health sciences, the predominant teaching methodology is traditional and emphasizes conveying knowledge. Nonetheless, new abilities must be taught now. This change shifts the prominence from professor to student and incorporates a concept called self-regulated learning, which involves the professor as a mediator and incorporates guidelines that facilitate learning diverse skills. Aim: To compare the effects of two teaching methodologies on the learning of key scientific concepts among health science students. Material and Methods: Two subgroups of equally complex concepts were randomly chosen to be taught either using traditional or self-regulation methodology. For the self-regulation methodology, two groups were formed. One learned only through self-regulation guidelines and the other learned through classes where the professor was a mediator. One hundred thirty seven freshman students from medicine, physical therapy, and nursing careers participated voluntarily in the study. Results: Self-regulation methodology impacted the learning process of scientific concepts in a positive way and showed significant differences with traditional teaching. The sole use of self-regulation guidelines alone generated similar results, compared to those obtained by students who attended lectures. Conclusions: Self-regulated learning would improve in learning efficiency and would reduce face-to-face class time.

Guías de práctica clínica: una introducción a su elaboración e implementación / Clinical practice guidelines development and implementation: an introduction

Clinical Practice Guidelines (CPG), defined as "statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options", are tools currently present in every level of our health system. This article introduces guidelines development and implementation processes and it reviews the Chilean experience. The main stages in a CPG development are question formulation, search and analysis of the existing evidence related to those questions, and making judgments about that evidence in order to formulate recommendations for clinical practice. At the national level, guidelines development processes are conducted by the Ministry of Health, and even when recent evaluations show some good results, there are a number of aspects - such as applicability - that should be improved. On the other hand, CPG should be implemented using effective strategies in order to obtain changes in clinical practice and patients' outcomes. The existing evidence about the effects of the different implementation strategies shows modest and highly variable results. At the national level, there is a dearth of research about the design and evaluation of implementation strategies, and most of it has been focused in the evaluation of adherence to specific recommendations.

Impacto de un programa de nivelación de ciencias básicas en estudiantes de primer año de la carrera de Medicina / Effects on academic performance of a leveling program in basic sciences in first year medical students

Background: A significant number of students in health careers do not have the knowledge to approve basic courses. Therefore, educational programs to level off knowledge have been developed. Aim: To associate the results of a leveling program with the academic performance in cell biology (CB) and biochemistry (BC) of first year medical students. Material and Methods: We applied a test to first year medical students at the beginning and end of the leveling program (control test). The results obtained at the end of the leveling program were correlated with the results obtained in CB and BC. Results: Fifty seven of89 (64%) first year medical students met the study entry criteria (54% female). Students who completed the leveling program had a significantly higher approval rate in CB (93% versus 75%, P = 0.024), and in BC (95% versus 69%, P = 0.001). After completing the leveling program, the risk of failing CB and BC, decreased by 72 and 84% respectively Conclusions: This study shows that medical students who participate in the leveling program decrease the chances of failing in CB and BC.

Informática biomédica / Biomedical informatics

Biomedical Informatics is a new discipline that arose from the need to incorporate information technologies to the generation, storage, distribution and analysis of information in the domain of biomedical sciences. This discipline comprises basic biomedical informatics, and public health informatics. The development of the discipline in Chile has been modest and most projects have originated from the interest of individual people or institutions, without a systematic and coordinated national development. Considering the unique features of health care system of our country, research in the area of biomedical informatics is becoming an imperative.

Torsión segmentaria derecha de epiplón mayor. Informe de un caso / Right-sided segmental infarction of the omentum. A case report

Describir un caso con torsión segmentaria derecha del epiplón mayor, de un paciente masculino de 28 años de edad, y analizar la literatura al respecto. Las torsiones e infartos del epiplón mayor, son entidades nosológicas raras. Esta entidad fue descrita por primera vez por Eitel en 1899, pero hasta 1981 sólo 233 casos habían sido informados en la literatura. Existen dos causas: la primera, o de causa desconocida, que es atribuible a un pedículo del epiplón muy angosto o muy largo y la lesión vascular debida a exceso de grasa; y la segunda, o de causa conocida, ocasionada por trauma externo, ejercicio violento o movimiento presitáltico muy acelerado. El diagnóstico preoperatorio es difícil y usualmente sólo se llega a él mediante una laparotomía exploradora y puede ser confundido con patologías tales como apendicitis aguda, pancreatitis, colecistitis aguda o úlcera duodenal perforada. Presentamos un caso que llego a nuestro hospital y requirió manejo quirúrgico, después de cinco días de evolución con dolor abdominal, y se encontró torsión segmentaria derecha de epiplón mayor. El diagnóstico preoperatorio es difícil de establecer por la inespecificidad de la clínica y el diagnóstico definitivo se establece durante la cirugía
