RESUMO

The protein profile of Bothrops rhombeatus venom was compared to Bothrops asper and Bothrops atrox, and the effectiveness of antivenoms from the National Institute of Health of Colombia (INS) and Antivipmyn-Tri (AVP-T) of Mexico were analyzed. Protein profiles were studied with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and reverse-phase high-performance liquid chromatography (RP-HPLC). The neutralizing potency and the level of immunochemical recognition of the antivenoms to the venoms were determined using Western blot, affinity chromatography, and enzyme-linked immunosorbent assay (ELISA). Bands of phospholipase A2 (PLA2), metalloproteinases (svMPs) I, II, and III as well as serine proteinases (SPs) in the venom of B. rhombeatus were recognized by SDS-PAGE. With Western blot, both antivenoms showed immunochemical recognition towards PLA2 and svMP. INS showed 94% binding to B. rhombeatus venom and 92% to B. asper while AVP-T showed 90.4% binding to B. rhombeatus venom and 96.6% to B. asper. Both antivenoms showed binding to PLA2 and svMP, with greater specificity of AVP-T towards B. rhombeatus. Antivenom neutralizing capacity was calculated by species and mL of antivenom, finding the following for INS: B. asper 6.6 mgV/mL, B. atrox 5.5 mgV/mL, and B. rhombeatus 1.3 mgV/mL. Meanwhile, for AVP-T, the following neutralizing capacities were found: B. asper 2.7 mgV/mL, B. atrox 2.1 mgV/mL, and B. rhombeatus 1.4 mgV/mL. These results show that both antivenoms presented similarity between calculated neutralizing capacities in our trial, reported in a product summary for the public for the B. asper species; however, this does not apply to the other species tested in this trial.

RESUMO

Work-related deaths are a persistent occupational health issue that can be prevented. However, prevention opportunities can be hampered by a lack of adequate public health resources. The Western States Occupational Network (WestON) is a network of federal, state, and local occupational health professionals that includes a 19-state region of the United States. To encourage public health collaboration, WestON partners examined work-related fatalities within the region. Fatality counts (numerators) were obtained from the U.S. Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries restricted-access research files for all workers ages ≥15 years and fatally injured in WestON states from 2011 through 2017. Estimates of full-time equivalent hours worked (FTE) (denominators) were retrieved from the BLS Current Population Survey. Annual average fatality rates were calculated as number of fatalities per 100,000 FTE over the study period. Rates were stratified by state, select demographics, industry sector, and event/exposure types. Pearson chi-squared tests and rate ratios with 95% confidence probability limits were used to assess rate differences. All analyses were conducted using SAS v.9.4. From 2011 through 2017, the annual average overall occupational fatality rate for the WestON region was 3.5 fatalities per 100,000 FTE, comparable to the overall U.S. fatality rate. Male workers had a fatality rate almost 10 times higher than female workers in the region. Fatality rates increased with successive age groups. Alaska and New Mexico had significantly higher fatality rates for all racial/ethnic groups compared to respective regional rates. Wyoming, North Dakota, and Montana had the three highest occupational fatality rates among foreign-born workers. Agriculture/forestry/fishing, mining/oil/gas extraction, and transportation/warehousing/utilities were industry sector groups with the three highest fatality rates regionally. Transportation-related incidents were the most frequent event type associated with occupational fatalities for all 19 states. Work-related fatalities are a crosscutting occupational public health priority. This analysis can be an impetus for collaborative multistate initiatives among a dynamic and varied occupational public health network to better meet the needs of a rapidly changing workforce.

RESUMO

Resumen Introducción: La ectasia coronaria (EC) es una remodelación patológica con una prevalencia mundial baja. Se define como una dilatación difusa mayor a 1.5 veces el diámetro de los segmentos adyacentes de esta o diferentes arterias coronarias. Objetivo: Documentar las características clínicas y angiográficas, y el tratamiento médico que reciben los pacientes con diagnóstico de EC en el Instituto Nacional de Cardiología (INC). Métodos: Estudio de tipo transversal con diseño no experimental descriptivo, con un muestreo por conveniencia no probabilístico. Resultados: De 69 pacientes que asistieron al INC con diagnóstico de EC la mayor parte eran hombres, con una media de edad de 56 ± 11 años, el factor de riesgo coronario más común en los pacientes con EC fue el tabaquismo, en 40 (58%); se asoció un infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en 45 (65.2%), de localización frecuente en la cara inferior 18 (40%), relacionado con la arteria más afectada, la coronaria derecha 48 (69.6%), seguida de la circunfleja 39 (56.5%). Destaca el uso preferente de la terapia antiplaquetaria dual con anticoagulante (APD+ACO) en 40 (58%) al egreso de cada paciente del INC. Conclusión: La EC es una remodelación patológica no infrecuente en el INC. En este estudio se evidenció que el SCA-IAMCEST es la manifestación más típica de la EC, la coronariografía diagnóstica identificó un Markis tipo 3, por lo que se esperaría una tasa baja de mortalidad y recurrencia de eventos cardiovasculares y a pesar de no existir un consenso sobre la terapia ideal, en el INC se prefiere el tratamiento individualizado, recomendando modificación en el estilo de vida y empleando como tratamiento médico el uso de la triple terapia (APD+ACO) solo al momento de egreso del paciente.

Abstract Introduction: Coronary Ectasia (CE) is a pathological remodeling with a low worldwide prevalence. It is defined as a diffuse dilatation greater than 1.5 times the diameter of the adjacent segments of the same or different coronary arteries. Objective: To document the clinical and angiographic characteristics, and medical treatment at the discharge of patients diagnosed with coronary ectasia who attended the National Institute of Cardiology (INC). Methods: Cross-sectional study with a non-experimental descriptive design, with a non-probabilistic convenience sampling. Results: Of 69 patients who attended the INC with a diagnosis of CD, most were men, with a mean age of 56 + 11 years, the most common coronary risk factor in patients with CE was smoking 58% (40); it was associated mostly with an acute myocardial infarction ST-segment elevation (STEMI) 65.2% (45), of frequent location in the lower face 40% (18), correlated with the most affected artery is the Right Coronary Artery (CD) 69.6% (48), followed by the circumflex (Cx) 56.5% (39). A mean LVEF of 47 + 9.72 was evident within the ventricular function. As well as the preferential use of dual antiplatelet therapy with anticoagulant (DAP + OAC) in 58% (40) at the discharge of each patient from the INC. Conclusion: CE is a not uncommon pathological remodeling in INC. This study showed that STEMI is the most typical manifestation of CE, diagnostic coronary angiography identified a type 3 Markis, so a low rate of mortality and recurrence of cardiovascular events would be expected, and despite the lack of consensus on the ideal therapy, at the INC individualized treatment is preferred, recommending lifestyle changes, and using triple therapy (DAP + OAC) as a medical treatment only at the time of patient discharge.

RESUMO

Alcohol-associated liver disease is one of the main causes of chronic liver disease. It comprises a clinical-histologic spectrum of presentations, from steatosis, steatohepatitis, to different degrees of fibrosis, including cirrhosis and severe necroinflammatory disease, called alcohol-associated hepatitis. In this focused update, we aim to present specific therapeutic interventions and strategies for the management of alcohol-associated liver disease. Current evidence for management in all spectra of manifestations is derived from general chronic liver disease recommendations, but with a higher emphasis on abstinence and nutritional support. Abstinence should comprise the treatment of alcohol use disorder as well as withdrawal syndrome. Nutritional assessment should also consider the presence of sarcopenia and its clinical manifestation, frailty. The degree of compensation of the disease should be evaluated, and complications, actively sought. The most severe acute form of this disease is alcohol-associated hepatitis, which has high mortality and morbidity. Current treatment is based on corticosteroids that act by reducing immune activation and blocking cytotoxicity and inflammation pathways. Other aspects of treatment include preventing and treating hepatorenal syndrome as well as preventing infections although there is no clear evidence as to the benefit of probiotics and antibiotics in prophylaxis. Novel therapies for alcohol-associated hepatitis include metadoxine, interleukin-22 analogs, and interleukin-1-beta antagonists. Finally, granulocyte colony-stimulating factor, microbiota transplantation, and gut-liver axis modulation have shown promising results. We also discuss palliative care in advanced alcohol-associated liver disease.

RESUMO

Abstract Background The chronic aspect that begins to characterize long COVID appeals to the need for interventions proposed by institutions such as the World Health Organization (WHO) and the National Institute for Health and Care Excellence (NICE) to manage the disease, emphasizing behavioral change and self-care. Objective To perform a narrative review of the psychological literature that offers intervention strategies in alignment with the recommendations of the long COVID management guidelines proposed by WHO and NICE. Method MEDLINE, EBSCO, Google Scholar, SciELO, PsycINFO, PubMed, Cochrane, and CONRICYT databases were consulted, using Boolean operators and keywords for an exhaustive search. Results The contributions of the studies were categorized into five intervention strategies based on WHO and NICE recommendation guidelines: Psychoeducation, Self-care, Support networks, Relaxation, and Goal setting. These are given a brief introduction and their relevance to the management of long COVID symptomatology is described. Discussion and conclusion The persistent condition of COVID-19 symptoms makes it necessary to recognize that lifestyle changes must be made, primarily focused on health care and prevention of worsening disease sequelae. These lifestyle changes can be achieved through behavior modification, focusing on protective factors such as education, self-care, support networks, relaxation techniques and, setting appropriate goals.

RESUMO

Objective: Over 6 million migrants and refugees from Venezuela have left their country in the past decade; 1 million of them reside in Peru. Venezuelan migrant and refugee women are known to have limited access to sexual and reproductive health care services (SRHS) and contraceptive usage. To date, research to understand factors influencing access to those services is limited. This study aims to determine which enabling and predisposing factors influence Venezuelan migrant and refugee women's access to SRHS and contraceptive usage. Methods: This is a retrospective cross-sectional study of the first survey administered to the Venezuelan population residing in the Peru in 2018. The survey covered six cities in the country (Metropolitan Lima, Callao, Tumbes, Cusco, Trujillo, Arequipa). The sample for the study included Venezuelan migrant women of reproductive age (15-49 years old). Anderson's Behavior Model of Health Services is the conceptual framework of the investigation. Logistic regression models were fit to examine the relationship between different predisposing and enabling factors and women's access to SRHS and contraceptive usage. Results: The sample size includes a total of 3378 Venezuelan women of reproductive age. 50.7% of the women were between the ages of 21-30 and over 90.6% of the sample were residing in Metropolitan Lima. Only 20.2% of the women reported they had access to modern contraceptives. Results from the study suggest having insurance, residing in Trujillo, and having a higher socio-economic status were associated with more access to certain sexual reproductive health care services and contraceptive usage. Conclusion: This study identified different predisposing and enabling factors relevant to the access to SRHS and contraceptive usage. Difference in access and usage are particularly pronounced based on insurance status, geographical location, and socio-economic status. Displaced Venezuelans will remain abroad for an extended period of time, if not permanently. Focus should shift from providing humanitarian aid to integrating the migrants and refugees, particularly the most vulnerable groups, into the local economic and healthcare system.

RESUMO

Background: Analysis of health inequalities by ethnicity is critical to achieving the Sustainable Development Goals. In Ecuador, similar to other Latin American countries, indigenous and afro-descendant populations have long been subject to racism, discrimination, and inequitable treatment. Although in recent years, Ecuador has made progress in health indicators, particularly those related to the coverage of Reproductive, Maternal, Neonatal and Child Health (RMNCH) interventions, little is known as to whether inequalities by ethnicity persist. Methods: Analysis was based on two nationally representative health surveys (2004 and 2012). Ethnicity was self-reported and classified into three categories (Indigenous/Afro-Ecuadorian/Mixed ancestry). Coverage data for six RMNCH health interventions were stratified for each ethnic group by level of education, area of residence and wealth quintiles. Absolute inequality measures were computed and multivariate analysis using Poisson regression was undertaken. Findings: In 2012, 74.4% of women self-identifying as indigenous did not achieve the secondary level of education and 50.7% were in the poorest quintile (Q1); this profile was relatively unchanged since 2004. From 2004 to 2012, the coverage of RMNCH interventions increased for all ethnic groups, and absolute inequality decreased. However, in 2012, regardless of education level, area of residence and wealth quintiles, ethnic inequalities remained for almost all RMNCH interventions. Indigenous women had 24% lower prevalence of modern contraceptive use (Prevalence ratio [PR] = 0.76; 95% IC: 0.7-0.8); 28% lower prevalence of antenatal care (PR = 0.72; 95% IC: 0.6-0.8); and 35% lower prevalence of skilled birth attendance and institutional delivery (PR = 0.65; 95% IC: 0.6-0.7 and PR = 0.65; 95% IC: 0.6-0.7 respectively), compared with the majority ethnic group in the country. Interpretation: While the gaps have narrowed, indigenous people in Ecuador continue in a situation of structural racism and are left behind in terms of access to RMNCH interventions. Strategies to reduce ethnic inequalities in the coverage services need to be collaboratively redesigned/co-designed. Funding: This paper was made possible with funds from the Bill & Melinda Gates Foundation [Grant Number: INV-007,594/OPP1148933].

RESUMO

BACKGROUND: Breastfeeding offers the best nutrition during the first months of life. Scholars have identified a dose-response association between breastfeeding duration and reduced risk for child morbidity and mortality. In upper-middle-income countries, including Mexico, maternal employment has been negatively associated with breastfeeding duration. Despite increasing numbers of women entering the workforce and disproportionately participating in the informal sector, where they are un-entitled to paid maternity leave, little is known about how these factors may affect breastfeeding practices. RESEARCH AIM: To determine whether household income moderated the association between maternal employment status (defined as unemployed, formal, and informal full- and part-time employed) and any breastfeeding for ≥ 6 months. METHODS: We conducted a cross-sectional study using retrospective secondary data from the 2018-2019 Mexican Health and Nutrition Survey. The analytic sample included data about 2,156 children aged 6-36 months. We computed logistic regression models stratified by household income. RESULTS: The association between maternal employment and breastfeeding duration varied by household income. Compared to unemployed women, among lower-income households, children were less likely to be breastfed for ≥ 6 months when the participants was part-time informally employed (AOR = 0.30, 95% CI [0.13, 0.69]). Among higher-income households, children were less likely to be breastfed for ≥ 6 months when the participants was full-time formally employed (AOR = 0.52, 95% CI [0.30, 0.88]). CONCLUSIONS: To increase breastfeeding duration, stakeholders need to continue strengthening and enforcing policies among formally employed women, and strategies are urgently needed to support women in the informal sector, particularly those in lower-income households.

RESUMO

Background: Population-based data on epidemiology of Inflammatory Bowel Diseases (IBD) in Brazil are scarce. This study aims to define temporal trends of incidence and prevalence rates of Crohn's disease (CD) and ulcerative colitis (UC) in Brazil. Methods: All IBD patients from the public healthcare national system were included from January 2012 to December 2020. Average Annual Percent Change (AAPC) and 95% confidence intervals (CI) were calculated using log-linear regression for incidence and binomial regression for prevalence. Moran's I autocorrelation index was used to analyse clustering of cities by level of prevalence. Findings: A total of 212,026 IBD patients were included. Incidence of IBD rose from 9.4 in 2012 to 9.6 per 100,000 in 2020 (AAPC=0.8%; 95% CI -0.37, 1.99); for UC, incidence increased from 5.7 to 6.9 per 100,000 (AAPC=3.0%; 95% CI 1.51, 4.58) and for CD incidence decreased from 3.7 to 2.7 per 100,000 (AAPC=-3.2%; 95% CI -4.45, -2.02). Prevalence of IBD increased from 30.0 in 2012 to 100.1 per 100,000 in 2020 (AAPC=14.8%; CI 14.78-14.95); for UC, from 15.7 to 56.5 per 100,000 (AAPC=16.0%; CI 15.94, 16.17); for CD from 12.6 to 33.7 per 100,000 (AAPC=12.1% CI 11.95, 12.02). A south-north gradient was observed in 2020 prevalence rates of IBD [I=0.40 (p<0.0001)], CD [I=0.22 (p<0.0001)] and UC [I=0.42 (p<0.0001)]. Interpretation: Incidence of CD is decreasing whereas of UC is increasing, leading to stabilization in the incidence of IBD from 2012 to 2020 in Brazil. Prevalence of IBD has been climbing with 0.1% of Brazilians living with IBD in 2020. Funding: None.

RESUMO

Resumo Neste artigo, analisam-se as transformações ocorridas no Programa de Reabilitação Profissional do Instituto Nacional do Seguro Social desde 2009. Considera-se que o referido serviço foi concebido e operacionalizado com base no chamado campo da Saúde do Trabalhador, mas sofreu, a partir de 2018, um processo de desestruturação. As características desse processo são reveladas por meio da análise dos manuais técnicos de procedimentos (2011, 2016 e 2018), pois neles se encontram concepções teóricas, regras de organização e objetivos do serviço. O artigo é desenvolvido em três partes que evidenciam, sequencialmente, a construção do campo da Saúde do Trabalhador, sua inserção na política pública de Previdência Social e, enfim, sua operacionalização e suas transformações por meio dos manuais de procedimentos. Os resultados revelam um processo de desestruturação do programa, que se afasta de uma concepção multidimensional da saúde do trabalhador, ao mesmo tempo que a dimensão biológica se torna central.

Abstract This article analyses the transformations that have taken place in the Professional Rehabilitation Program of the Brazilian Institute of Social Security since 2009. It is considered that the aforementioned service was conceived and operated based on the so-called field of Workers' Health, but since 2018 suffered a process of disruption. The characteristics of this process are revealed through the analysis of technical manuals of procedures (2011, 2016 and 2018), as they contain theoretical concepts, organization rules and service objectives. The article is developed in three parts that sequentially show the construction of the Workers' Health field, its insertion in the Social Security public policy and, finally, its operationalization and its transformations through manuals of procedures. The results reveal a process of de-structuring of the program, which moves away from a multidimensional conception of worker's health, while the biological dimension becomes central.

RESUMO

A novel functional drink with nutraceutical properties was formulated from the aqueous extracts of Ilex guayusa, and Vernonanthura patens leaves, and cocoa husks. This juice contains various bioactive compounds, such as phenolic compounds and methylxanthines, with antioxidant and stimulant properties of pharmacological interest. However, it is known whether herbal extracts' interaction may have adverse toxic effects on human health. To evaluate this functional drink's innocuity, we estimated the acute oral toxicity (AOT) in experimental mice. This paper presents the AOT evaluation of two formulations of a functional drink (pre-formulation and microencapsulation) at a single dose of 2000 mg/kg of body weight (b.w.). No signs of adverse toxicity and mortality were observed after a single oral dose of 2000 mg/kg b.w. Likewise, no significant body and organ weight changes, food and water consumption behavior, and no histopathological changes were observed in the main organs evaluated. In conclusion, this functional drink can be categorized as low toxicity " according to the Globally Harmonized Classification System (GHS), making it a potential beverage with high nutritional and pharmacological value.

RESUMO

Domain analysis by means of scientific collaboration enables evidencing aspects that are involved in the establishment of relationships between researchers and institutions, such as the influence of institutional management models for the development of collaborative networks. This article aims to analyze the domain through the scientific collaboration network of the National Institute of the Atlantic Forest (INMA), a research unit currently affiliated to the Brazilian Ministry of Science, Technology and Innovation (MCTI), formerly known as the Professor Mello Leitão Museum of Biology (MBML), in order to acknowledge the institutional research identity in its historical journey as a public institution. It is thus analyzed how co-authorship constitutes this network and what research profile it reveals. Co-authorship analysis is adopted as a methodology, as well as the analysis of administrative documents with the survey and categorization of employees, regarding their types of ties to the institution, combined with searches in the Scopus database for the corroboration of institutional affiliations. A corpus of 138 articles published by 41 researchers from 1993 to 2019 is consolidated in this base, which represents 44% of the Institute's total research collaborators (93 collaborators). Of these 41, 92.5% have temporary links, such as scholarship holders and/or volunteers, with the remaining being public workers. It is recognized that the citation impact of the scientific production of scholarship holders, consigned to the Institute, is less than the citation impact of the volunteers' and public workers' production. It is evidenced that eight of the ten publications with the greatest impact and thematic prominence correspond to the field of zoology, with emphasis on the fields of herpetology and primatology. Macro-level collaborative relations are more intense with the United States, in both areas mentioned, covering 16% of the total corpus of articles in cooperation with that country. Zoology, besides its greater impact, accounts for more than half of the corpus production (65.9%).On the other hand, botany is responsible for 30.4% of the corpus, with its dispersed international cooperation in a broad variety of countries. Individual authorship articles are 57% consigned to botany. In summary, the accomplished analysis will contribute to the development of institutional domain analysis methodologies that present scientific collaboration as a basic procedure.

RESUMO

Objectives: In clinical trials of pediatric trichotillomania (TTM), three instruments are typically employed to rate TTM severity: (1) the Massachusetts General Hospital Hair Pulling Scale (MGH-HPS), (2) the National Institute of Mental Health Trichotillomania Severity Scale (NIMH-TSS), and (3) the Trichotillomania Scale for Children (TSC). These instruments lack standardized definitions of treatment response, which lead researchers to determine their own definitions of response post hoc and potentially inflate results. We performed a meta-analysis to provide empirically determined accuracy measures for percentage reduction cut points in these three instruments. Methods: MEDLINE was searched for TTM clinical trials. A total of 67 studies were initially identified, but only 5 were clinical trials focused on TTM in pediatric populations and therefore were included in this meta-analysis (n = 180). A Clinical Global Impressions Improvement score ≤2 was used to define clinical response. Receiver operating characteristic principles were employed to determine accuracy measures for percentage reduction cut points on each one of the instruments. Meta-DiSc software was employed to provide pooled accuracy measures for each cut point for each instrument. The Youden Index and the distance to corner methods were used to determine the optimal cut point. Results: The optimal cut points to determine treatment response were a 45% reduction on the MGH-HPS (Youden Index 0.40, distance to corner 0.20), a 35% reduction on the NIMH-TSS (Youden Index 0.42, distance to corner 0.17), a 25% reduction on the TSC child version (TSC-C; Youden Index 0.40, distance to corner 0.18), and a 45% (distance to corner 0.30) or 50% reduction (Youden Index 0.33) on the TSC parent version (TSC-P). The TSC-C had less discriminative ability at determining response in younger children in comparison to older children; no age-related differences were observed on the TSC-P. Conclusions: This study provides empirically determined cut points of treatment response on three instruments that rate TTM severity. These data-driven cut points will benefit future research on pediatric TTM.

RESUMO

This paper analyzes the situation and the changes made in the Institute of Sanitary and Tropical Diseases between 1965 and 1989 to become the National Institute of Epidemiological Diagnosis and Reference. Three major stages are identified during this period: crisis, transition and renewal. The factors that led to the crisis, the decisions made to overcome it and to harmonize the work of laboratories with epidemiological and public health criteria are discussed. The recognition obtained by researchers of the Institute despite the crisis is described, as well as the way the institution managed to continue with projects despite the changing global situation. The transition included the arrival of a new generation of professionals with modern computer-based and conceptual tools and the remarkably well met challenge of participating in national surveys with rigorous criteria. All this moved the institution to define its profile towards diagnosis and reference.

El artículo analiza la situación y los cambios efectuados en el Instituto de Salubridad y Enfermedades Tropicales entre 1965 y 1989 para transformarse en el Instituto Nacional de Diagnóstico y Referencia Epidemiológicos. Se identifican tres grandes etapas en el periodo: crisis, transición y renovación. Se señalan los elementos que llevaron a la crisis, las decisiones que se tomaron para salir de ella y armonizar el trabajo de los laboratorios con criterios epidemiológicos y de salud pública. Se citan las distinciones obtenidas por investigadores del Instituto a pesar de la crisis y se describe cómo la institución logró seguir con proyectos a pesar de la cambiante situación mundial. La transición incluyó la llegada de una nueva generación de profesionales con modernas herramientas informáticas y conceptuales y el desafío de participar en encuestas nacionales con criterios rigurosos.

RESUMO

El estudio de la enseñanza de la medicina, desde una perspectiva histórica, es importante para explicar el desarrollo de esta profesión. Considerando el valor de los libros en el currículo universitario su estudio permite comprender la influencia sociopolítica del momento histórico. El objetivo de este trabajo fue determinar y analizar la primera bibliografía utilizada en la formación de médicos en Chile entre 1758 y 1840 (desde la fundación de la Universidad de San Felipe a la muerte del Dr. Pedro Morán). A través de una investigación histórica se logró encontrar los ocho libros de textos utilizados durante este periodo. De ellos, se realizó un análisis descriptivo que abarcó la identificación del autor, el título de la obra, el año, idioma y lugar de publicación. Además, se clasificaron según extensión y enfoque. También se realizó un análisis cuantitativo para determinar la cantidad de información que presentan estos libros en comparación con la literatura moderna. Los resultados se ordenaron en tablas y gráficos para su posterior análisis. Los textos encontrados fueron principalmente editados en España y en idioma español (62,5 %), aunque una parte importante fueron editados en Francia y en francés (37,5 %). Mayoritariamente se utilizó bibliografía de autores franceses (50 %), aunque también se incluyeron libros de autores españoles (37,5 %) y alemanes (12,5 %). Con respecto a la extensión de los textos, tanto los libros de mediana y gran extensión estuvieron representados de igual forma (37,5 %) y los compendios representaron un porcentaje menor (12,5 %). Este trabajo es un aporte a la comprensión del origen de la formación de médicos en Chile y ayuda a comprender el nacimiento de la identidad profesional, que ha sido de gran influencia en la historia político - social de Chile, describiendo la bibliografía que marco el nacimiento de la Historia de la Anatomía en nuestro país.

The study of the teaching of medicine, from a historical perspective, is important to explain the development of this profession. Considering the value of books in the university curriculum, its study allows us to understand the socio-political influence of the historical moment. The objective of this work was to determine and analyze the first bibliography used in the training of doctors in Chile between 1758 and 1840 (from the foundation of the University of San Felipe to the death of Dr. Pedro Morán).Through a historical investigation it was possible to find the eight textbooks used during this period. Of these, a descriptive analysis was carried out that included the identification of the author, the title of the work, the year, language and place of publication. In addition, they were classified according to extension and focus. A quantitative analysis was also carried out to determine the amount of information presented in these books compared to modern literature. The results were arranged in tables and graphs for later analysis. The texts found were mainly published in Spain and in Spanish (62.5 %), although an important part was published in France and in French (37.5 %). The bibliography of French authors was used mainly (50 %), although books by Spanish authors (37.5 %) and Germans (12.5 %) were also included. With respect to the extension of the texts, both the medium and large extension books were represented in the same way (37.5 %) and the compendiums represented a smaller percentage (12.5 %). This work is a contribution to the understanding of the origin of the training of doctors in Chile and helps to understand the birth of professional identity, which has been of great influence in the political - social history of Chile, describing the bibliography that marked the birth of the History of Anatomy in our country.
