Knowledge and attitudes of health professionals in Chile towards people living with human immunodeficiency virus: A cross-national survey.

Introduction: People living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) often experience discrimination from both other individuals and the health personnel who care for them. Chile has experienced a marked increase in the number of new HIV cases.Methods: Prospective cross-sectional study. The HIV/AIDS questionnaire for providers and health personnel was obtained from the International Planned Parenthood Federation, initially carrying out a pilot test and evaluating its validity.Results: A total of 784 health professionals answered the questionnaire correctly. Among them, 68.4% (n = 536) were women, and 36.2% (n = 284) were physicians. The study revealed that more than 90% of respondents had a positive attitude towards caring for people living with HIV, and more than 75% did not mind buying food from them or sharing services with them. Furthermore, more than 99% rejected the religiously endorsed labeling of people living with HIV/AIDS as immoral. Additionally, 95.5% (n = 749) mentioned that they did not feel anxious about knowing whether the next patient on their care list was living with HIV, and 76.9% (n = 603) of the respondents felt safe taking blood samples.Conclusions: Chilean health professionals have good knowledge about HIV infection and its mode transmission. Their attitudes towards people living with HIV are also generally positive.

Relationship between Duffy Genotype/Phenotype and Prevalence of Plasmodium vivax Infection: A Systematic Review.

The Duffy protein, a transmembrane molecule, functions as a receptor for various chemokines and facilitates attachment between the reticulocyte and the Plasmodium Duffy antigen-binding protein. Duffy expression correlates with the Duffy receptor gene for the chemokine, located on chromosome 1, and exhibits geographical variability worldwide. Traditionally, researchers have described the Duffy negative genotype as a protective factor against Plasmodium vivax infection. However, recent studies suggest that this microorganism's evolution could potentially diminish this protective effect. Nevertheless, there is currently insufficient global data to demonstrate this phenomenon. This study aimed to evaluate the relationship between the Duffy genotype/phenotype and the prevalence of P. vivax infection. The protocol for the systematic review was registered in PROSPERO as CRD42022353427 and involved reviewing published studies from 2012 to 2022. The Medline/PubMed, Web of Science, Scopus, and SciELO databases were consulted. Assessments of study quality were conducted using the STROBE and GRADE tools. A total of 34 studies were included, with Africa accounting for the majority of recorded studies. The results varied significantly regarding the relationship between the Duffy genotype/phenotype and P. vivax invasion. Some studies predominantly featured the negative Duffy genotype yet reported no malaria cases. Other studies identified minor percentages of infections. Conversely, certain studies observed a higher prevalence (99%) of Duffy-negative individuals infected with P. vivax. In conclusion, this systematic review found that the homozygous Duffy genotype positive for the A allele (FY*A/*A) is associated with a higher incidence of P. vivax infection. Furthermore, the negative Duffy genotype does not confer protection against vivax malaria.

CEA-delta could be a biomarker of tumor phenotype, clinical stage, and chemotherapeutic response in rectal cancer with OCT4-positive cancer stem cells.

Background: There is very limited evidence on biomarkers for evaluating the clinical behavior and therapeutic response in rectal cancer (RC) with positive expression of cancer stem cells (CSCs). Methods: An exploratory prospective study was conducted, which included fresh samples of tumor tissue from 109 patients diagnosed with primary RC. Sociodemographic, pathological and clinical characteristics were collected from medical records and survey. The OCT4 protein was isolated using the Western Blot technique. It was calculated the ΔCEA, ΔOCT4, and ΔOCT4/GUSB values by assessing the changes before and after chemotherapy, aiming to evaluate the therapeutic response. Results: Patients had an average age of 69.9 years, with 55% (n=60) being male. Approximately 63.3% of the tumors were undifferentiated, and the most frequent staging classification was pathological stage III (n=64; 58.7%). Initial positive expression was observed in 77.1% of the patients (n=84), and the median ΔCEA was -1.03 (-3.82 - 0.84) ng/ml, with elevated levels (< -0.94 ng/ml) found in 51.4% of the subjects (n=56). Being OCT4 positive and having an elevated ΔCEA value were significantly associated with undifferentiated tumor phenotype (p=0.002), advanced tumor progression stage (p <0.001), and negative values of ΔOCT4 (p <0.001) (suggestive of poor therapeutic response) compared to those without this status. Conclusion: This study identified a significant and directly proportional association among the values of ΔCEA, ΔOCT4, and ΔOCT4/GUSB. These findings suggest that ΔCEA holds potential as a clinical biomarker for determining the undifferentiated tumor phenotype, advanced clinical stage, and poor therapeutic response in RC with CSCs positive expression.

Knowledge, attitudes and experience of physicians working in Chile toward the prescription of pre-exposure prophylaxis (PrEP): A cross-national survey.

BACKGROUND: Pre-exposure prophylaxis (PrEP) involves administering antiretroviral drugs to prevent human immunodeficiency virus (HIV) infection in at-risk subjects. Chile is considered one of the countries with the highest number of new cases per year of HIV infections. METHODS: A nationwide cross-sectional study was carried out in Chile. A questionnaire of physicians' attitudes toward the prescription of PrEP was used. RESULTS: 632 doctors responded correctly the survey. 58.5% (n = 370) were women, and median age was 34 years (IQR 25-43). 55.4% (n = 350) responded that they have never prescribed antiretrovirals for HIV-negative individuals to prevent HIV infection, and only 10.1% have prescribed PrEP. 60.8% (n = 384) mentioned having informed about the possibility of using antiretroviral post-exposure prophylaxis in case of risky sexual activity. 76.3% (n = 482) believed each institution should formulate internal protocols for administering these drugs, and 98.4% (n = 622) stated that with the currently available evidence, PrEP should be suggested to cope with the HIV pandemic. CONCLUSION: It was concluded that knowledge, attitudes and experience toward PrEP prescribing are variable and related to patient care. However, Chile has a marked tendency in favor of this therapy, which is similar to that reported in studies worldwide.

Mapping Dengue in children in a Colombian Caribbean Region: clinical and epidemiological analysis of more than 3500 cases.

Dengue continues to be a global public health problem due to its impact in terms of morbidity and mortality and economic burden on health systems, with severe effects mainly on children. Among the objectives of sustainable development is the control of infectious diseases; therefore, it is necessary to evaluate the impact of existing programs on the prevention and management of infectious diseases. The aim of this study was to analyze the epidemiological, clinical, and geospatial behavior of dengue in children in a region of the Colombian Caribbean. A retrospective cross-sectional study was carried out. The data provided by the Municipal Health Secretariat were taken and the cases of dengue and severe dengue in children aged 0 to 17 years reported in Sincelejo, Colombia, were extracted. The sociodemographic and clinical characteristics presented were analyzed and descriptive statistics were performed with tables and graphs of frequency and accumulated percentages. To locate the areas with the highest incidence of cases during the year, a geospatial location of the cases was carried out with the QGIS v.3.8 program. In 2019, there were 3611 cases of dengue fever in children aged 0 to 17 years. There were 1394 (38.6%) cases with warning signs, and 41 (1.1%) cases of severe dengue fever. Cases of severe dengue fever occurred more frequently in women. The incidence rate found was 3927 and 45.1 cases per 100,000 population, for dengue and severe dengue in children, respectively. The age ranges with the highest number of cases were children aged 4 to 9 years with 1778 cases. The clinical presentation was varied, with the most frequent symptoms, in all groups, being fever in 100% of cases, myalgias ≥71%, and arthralgias ≥64%. Only 9% (n=315) of the cases, corresponded to cases in the rural area. A very high incidence of cases of dengue and dengue with alarm signs in children was evidenced in the Colombian Caribbean region, mainly in the urban area, despite the existence of public health programs and strategies to control the burden of diseases transmitted by arbovirus vectors.

Eutanasia y suicidio asistido: revisión y análisis de marcos legales internacionales comparados con Colombia

El avance en materia de derechos humanos es indispensable durante el desarrollo de políticas públicas en salud y marcos legales que garanticen el cuidado integro de la salud; la eutanasia y suicidio asistido siguen siendo conceptos ampliamente discutidos desde la medicina, y especialmente en la bioética por el peso que poseen en la toma de decisiones del paciente terminal y cuidados paliativos. Estos términos, su uso, aprobación y regulación legal dependen de la influencia de diversos determinantes como la investigación biomédica, las creencias religiosas, los aspectos socioculturales, entre otros. Sin embargo, lo que permite la interpretación y observación de resultados son las practicas soportadas por las legislaciones de cada país; Colombia es el único país que ha despenalizado la eutanasia en la región y que progresa activamente en temas relacionados. En este orden de ideas, el objetivo de esta revisión consiste en analizar los marcos legales internacionales sobre la definición y uso de la eutanasia y el suicidio asistido, que permitan comprender la evolución de la normatividad sobre el cuidado al final de la vida.

Advances in human rights are indispensable during the development of public policies in health and legal frameworks that guarantee integral health care; euthanasia and assisted suicide continue to be concepts widely discussed in medicine, and especially in bioethics due to the weight they have in the decision-making process of the terminal patient and palliative care. These terms, their use, approval, and legal regulation depend on the influence of various determinants such as biomedical research, religious beliefs, and sociocultural aspects. However, what allows the interpretation and observation of results are the practices supported by the legislation of each country; Colombia is the only country that has decriminalized euthanasia in the region and is actively progressing in related issues. In this order of ideas, the objective of this review is to analyze the international legal frameworks on the definition and use of euthanasia and assisted suicide to understand the evolution of regulations on end-of-life care.

Os avanços nos direitos humanos são indispensáveis para o desenvolvimento de políticas públicas de saúde e marcos legais que garantam a atenção integral à saúde. A eutanásia e o suicídio assistido continuam sendo conceitos amplamente discutidos na medicina e, principalmente, na bioética, devido ao peso que têm no processo de tomada de decisão de pacientes terminais e nos cuidados paliativos. Esses termos, seu uso, aprovação e regulamentação legal dependem da influência de vários determinantes, como pesquisas biomédicas, crenças religiosas, aspectos socioculturais, entre outros. No entanto, o que permite a interpretação e a observação dos resultados são as práticas apoiadas pela legislação de cada país; a Colômbia é o único país que descriminalizou a eutanásia na região e está avançando ativamente em questões relacionadas. O objetivo desta revisão é analisar as estruturas jurídicas internacionais sobre a definição e o uso da eutanásia e do suicídio assistido a fim de compreender a evolução das regulamentações de cuidados no fim da vida.

Euthanasia and assisted suicide: An in-depth review of relevant historical aspects.

End-of-life care is an increasingly relevant topic due to advances in biomedical research and the establishment of new disciplines in evidence-based medicine and bioethics. Euthanasia and assisted suicide are two terms widely discussed in medicine, which cause displeasure on many occasions and cause relief on others. The evolution of these terms and the events associated with their study have allowed the evaluation of cases that have established useful definitions for the legal regulation of palliative care and public policies in the different health systems. However, there are still many aspects to be elucidated and defined. Based on the above, this review aimed to compile relevant historical aspects on the evolution of euthanasia and assisted suicide, which will allow understanding the use and research of these terms.

Brain-lung interaction: a vicious cycle in traumatic brain injury.

The brain-lung interaction can seriously affect patients with traumatic brain injury, triggering a vicious cycle that worsens patient prognosis. Although the mechanisms of the interaction are not fully elucidated, several hypotheses, notably the "blast injury" theory or "double hit" model, have been proposed and constitute the basis of its development and progression. The brain and lungs strongly interact via complex pathways from the brain to the lungs but also from the lungs to the brain. The main pulmonary disorders that occur after brain injuries are neurogenic pulmonary edema, acute respiratory distress syndrome, and ventilator-associated pneumonia, and the principal brain disorders after lung injuries include brain hypoxia and intracranial hypertension. All of these conditions are key considerations for management therapies after traumatic brain injury and need exceptional case-by-case monitoring to avoid neurological or pulmonary complications. This review aims to describe the history, pathophysiology, risk factors, characteristics, and complications of brain-lung and lung-brain interactions and the impact of different old and recent modalities of treatment in the context of traumatic brain injury.

Cursos en línea masivos y abiertos para educación continua: una herramienta que debe ser aprovechada por el estudiante y el profesional de la salud / Massive open online courses for continuing education: a tool for health students and professionals

Los cursos en línea masivos y abiertos han surgido como una estrategia pedagógica con un crecimiento exponencial en la última década. Han sido catalogados como la próxima evolución del aprendizaje a través de las redes, con la capacidad de romper las barreras hacia la formación académica y de promover habilidades, tanto teóricas como prácticas, en todas las áreas del conocimiento. El objetivo de este estudio consiste en exponer evidencia respecto a la utilidad de los cursos en línea en el desarrollo integral del estudiante y profesional de la salud. Se realizó una búsqueda no sistemática de la literatura, sin límite de fecha y hasta octubre del año 2020; se utilizaron términos como health personnel, health occupations students, distance education y massive open online courses, además de sinónimos combinados con los operadores AND y OR, en las bases PubMed, Science Direct y EBSCO. Los cursos en línea masivos y abiertos enfocados en el área de la salud, pueden ser una estrategia fuerte y efectiva para estimular un cambio educativo a nivel global, con el fin de mitigar las necesidades que actualmente azotan al mundo; además, la educación es la herramienta primordial para garantizar el crecimiento social, por lo tanto, si se refuerza el acceso al conocimiento para las poblaciones más vulnerables y grupos de cualquier edad, se puede esperar que el autocuidado y los estilos de vida saludable se conviertan en la prioridad de cada ser humano, y contribuyan a disminuir tasas de morbilidad, mortalidad y costos en salud(AU)

Massive open online courses have become an exponentially growing pedagogical strategy in the last decade. They have been categorized as the next evolution of network learning, with the capacity of breaking the barriers toward academic training, fostering theoretical and practical skills in all areas of knowledge. The purpose of this study is to present evidence of the usefulness of online courses for the comprehensive development of medical students and health professionals. A non-systematic search was conducted of the literature on the topic published in the databases PubMed, Science Direct and EBSCO on any date until October 2020, using search terms such as health personnel, health occupations students, distance education and massive open online courses, as well as their synonyms, combined with the operators AND and OR. Massive open online courses on health topics may be a strong, effective strategy to encourage a massive worldwide educational change aimed at mitigating the needs currently posed to the world. Education being the main tool to achieve social growth, if access to knowledge is reinforced among the most vulnerable populations of all age groups, it may be expected that self-care and healthy lifestyles will become a priority for all human beings, thus contributing to improve morbidity and mortality rates and reduce health care costs(AU)

Endometriosis cutánea primaria umbilical: a propósito de un caso / Umbilical Primary Cutaneous Endometriosis: A Case Report / Endometriose cutânea primária umbilical: relato de caso

Introducción: la endometriosis es una de las patologías ginecológicas más frecuentes, que se entiende como la implantación intrapélvica de tejido endometrial, sensible, en la gran mayoría de casos, al influjo hormonal. Extrauterinamente, se caracteriza por la presencia de glándulas y estroma endometrial en órganos o tejidos no ginecológicos. Sin embargo, la piel corresponde a uno de los sitios con menor fre-cuencia de implantación, ya sea de forma primaria o secundaria. Se calcula la incidencia de endometrio-sis cutánea en la zona umbilical en menos del 1 % de los casos. Presentación del caso: mujer de 36 años de edad, quien consulta con Cirugía General por un cuadro clínico de dos años de evolución, consistente en lesiones sobrelevantadas de la piel en la región umbilical, de color café oscuro, las cuales describe como dolorosas y sangrantes en el momento del ciclo menstrual. A pesar de haber sido resecadas en dos ocasiones, se encontró persistencia del cuadro. Discusión: la endometriosis cutánea primaria umbilical representa del 0.5 al 1.0 % de todas las pacientes con endometriosis ectópica, y el ombligo es uno de los sitios menos comunes de implantación. Esta condición afecta alrededor del 5 al 15 % de mujeres en edad fértil, y del 3 al 5 % de mujeres en edad menopaúsica. La presentación clínica más común se basa en una masa palpable, sangrado umbilical y dolor regular o irregular abdominal. Al asociar la endometriosis extrapélvica con la presencia de endometriosis pélvica, solamente alrededor del 20 % de las pacientes presentará esta última

Introduction: Endometriosis is one of the most frequent gynecological pathologies, understood as an intrapelvic implantation of endometrial tissue, sensitive to hormonal influence in most cases. At the extrauterine level, it is characterized by the presence of endometrial glands and stroma in the non-gy-necological organs or tissues. However, the skin corresponds to one of the sites with the least frequency of implantation, either primary or secondary, with the incidence of cutaneous endometriosis being calculated at the umbilical level in <1% of the cases. Case presentation: A 36-year-old female patient presented to the General Surgery department with a two-year history of dark brown, raised skin lesions in the umbilical region, which she described as painful, and bleeding at the time of the menstrual cycle. Despite having been resected twice, the condition still persisted. Discussion: Umbilical primary cutane-ous endometriosis represents 0.5%­1.0% of all patients with ectopic endometriosis, with the navel being one of the least common implantation sites. This condition affects about 5%−15% of women of childbear-ing age, and 3%−5% women of menopausal age. The most common clinical presentation is based on the palpable mass, umbilical bleeding, regular or irregular abdominal pain. Associating extrapelvic endo-metriosis with the presence of pelvic endometriosis, only about 20% of the patients will have the latter

Introdução: a endometriose é uma das patologias ginecológicas mais frequentes, entendida como o implante intrapélvico de tecido endometrial, sensível na grande maioria dos casos à influência hor-monal. No nível extrauterino, é caracterizada pela presença de glândulas e estroma endometriais em órgãos ou tecidos não ginecológicos. Porém, a pele corresponde a um dos locais com menor frequência de implantação, seja ela primária ou secundária, calculando-se a incidência de endometriose cutânea ao nível umbilical em menos de 1% dos casos. Apresentação do caso: paciente do sexo feminino, com 36 anos de idade, que consulta para Cirurgia Geral devido a quadro clínico de 2 anos de evolução, cons-tituído por lesões cutâneas elevadas na região umbilical, de coloração marrom-escura, que descreve como dolorosas e com sangramento no momento do ciclo menstrual. Apesar de ter sido ressecado em 2 ocasiões, o quadro era persistente. Discussão: a endometriose cutânea primária umbilical representa 0.5%-1.0% de todas as pacientes com endometriose ectópica, sendo o umbigo um dos locais de implan-tação menos comuns. Essa condição afeta cerca de 5% a 15% das mulheres em idade reprodutiva e 3% a 5% das mulheres em menopausa. A apresentação clínica mais comum baseia-se em massa palpável, sangramento umbilical, dor abdominal regular ou irregular. Ao associar a endometriose extrapélvica à presença de endometriose pélvica, apenas cerca de 20% das pacientes a apresentarão

Diferencias entre los modelos de riesgo Framingham y DAD en la evaluación del riesgo cardiovascular en pacientes con VIH bajo terapia antirretroviral: experiencia en una población del caribe colombiano / Differences between the Framingham and D:A:D risk models for cardiovascular risk assessment in HIV-positive patients on antiretroviral therapy: an experience in a Colombian Caribbean population

RESUMEN Objetivo: Evaluar el riesgo de enfermedad cardiovascular a cinco y a diez años en pacientes con infección por VIH en terapia antirretroviral, por medio de las escalas Framingham y Data collection on Adverse Effects of Anti-HIV Drugs Study. Materiales y métodos: Estudio observacional de corte transversal y prospectivo. Se incluyeron pacientes con infección por el VIH en tratamiento antirretroviral de un centro de referencia para pacientes con VIH, entre el 1 de enero y el 30 de abril de 2019. Se realizó evaluación del riesgo cardiovascular a cinco y a diez años a través de los modelos de predicción de Framingham y la escala Data collection on Adverse Effects of Anti-HIV Drugs Study (DAD), y una comparación entre ellos a través de modelos estadísticos. Resultados: Se incluyeron 159 pacientes, con un promedio de edad de 48,90 años ± 9,90. La media de valoración del riesgo cardiovascular por escala de Framingham a 5 años fue de 2,70 % ± 2,80; Framingham a 10 años fue 6,10 % ± 5,70; DAD a 5 años, 3,50 % ± 4,10; DAD a 10 años, de 6,90 % ± 7,70; y el riesgo escala de Framingham a 10 años recalculado para Colombia (multiplicado por 0,75) fue de 4,50 ± 4,20. A través de un modelo de regresión logística, se determinó que la puntuación con mayor número de variables significativamente relacionadas con el resultado de riesgo cardiovascular alto es el modelo DAD a 10 años. Conclusiones: El estudio evidenció una diferencia significativa, con mayor riesgo estimado de enfermedad cardiovascular al utilizar el modelo DAD en comparación con el Framingham, tanto para la estimación a cinco años como a diez.

ABSTRACT Objective: To assess the five- and ten-year cardiovascular disease risk in HIV-positive patients on antiretroviral therapy, using the Framingham risk score and the Data collection on adverse effects of anti-HIV drugs (D:A:D) study. Materials and methods: An observational prospective cross-sectional study. HIV-positive patients on antiretroviral treatment from a referral center for HIV patients were included in the study between January 1 and April 30, 2019. A five- and ten-year cardiovascular risk assessment was performed using the Framingham risk score and the D:A:D study. Additionally, both risk models were compared through statistical models. Results: The study population consisted of 159 patients with a mean age of 48.90 years ± 9.90. The mean cardiovascular risk according to the five-year Framingham risk score was 2.70 % ± 2.80, the ten-year Framingham risk score was 6.10 % ± 5.70, the five-year D:A:D study was 3.50 % ± 4.10, the ten-year D:A:D study was 6.90 % ± 7.70, and the ten-year Framingham risk score recalculated for Colombia (multiplied by 0.75) was 4.50 % ± 4.20. Using a logistic regression model, it was determined that the ten-year D:A:D study provided the greatest number of variables significantly related to a high cardiovascular risk. Conclusions: The study showed a significant difference between the risk models. Both the five- and ten-year D:A:D study provided a better cardiovascular disease risk estimation than the five- and ten-year Framingham model.

Validación de los criterios predictivos de alto riesgo para coledocolitiasis de la Sociedad Americana de Endoscopia Gastrointestinal, 2010: Experiencia de un centro del caribe colombiano / Validation of the predictive criteria of high risk for choledocholithiasis of the american society for Gastrointestinal Endoscopy, 2010: experience of a Colombian Caribbean Center

Introducción: La colangiopancreatografía retrógrada endoscópica (CPRE) se ha convertido en el estándar de oro para el diagnóstico y tratamiento de la coledocolitiasis. La Sociedad Americana de Endoscopia Gastrointestinal (ASGE) propuso en 2010 estratificar a los pacientes en 3 niveles de riesgo; sin embargo, los estudios han encontrado resultados controvertidos sobre los parámetros predictivos de estos criterios diagnósticos. El objetivo de este estudio consiste en determinar el desempeño de los criterios predictivos de alto riesgo de la ASGE 2010 en el diagnóstico de coledocolitiasis en una población del Caribe colombiano. Métodos: Estudio transversal retrospectivo, en el que se incluyeron pacientes con sospecha de coledocolitiasis, y que fueron llevados a evaluación por CPRE, cumpliendo los criterios propuestos por la ASGE de alta probabilidad. El resultado obtenido se comparó con la presencia de coledocolitiasis en la CPRE, a partir de la cual se estimaron los valores y los intervalos de confianza del 95% para la sensibilidad, la especificidad, el valor predictivo positivo y negativo, y la razón de probabilidad positiva y negativa. Resultados: En este estudio se incluyeron los datos de 118 pacientes. La edad media de los pacientes era de 46 años (RIQ= 31; 17- 89); el 78% (n= 92) eran mujeres. El 65,3% (n= 77) eran mayores de 55 años. El resultado de la CPRE fue positivo en el 81,4% (n= 96) de los pacientes. La presencia de un perfil hepático alterado (90%) resultó ser la prueba más sensible, la colangitis clínica (86%) la más específica, la presencia de litiasis ductal por US (85%) fue la prueba con mayor valor predictivo positivo, y la presencia de litiasis ductal por US (35%) fue la prueba con mayor valor predictivo negativo. Conclusión: Los parámetros predictivos de los criterios de la ASGE 2010 para el diagnóstico de coledocolitiasis muestran variabilidad con respecto al rendimiento propuesto en las guías.

Introduction: Endoscopic retrograde cholangiopancreatography (ERCP) has become the gold standard for diagnosis and treatment of choledocholithiasis. The American Society for Gastrointestinal Endoscopy (ASGE) in 2010 proposed stratifying patients into 3 risk levels; however, studies have found controversial results about the predictive parameters of these diagnostic criteria. The objective of this study is to determine the performance of the high-risk predictive criteria of the ASGE 2010 in the diagnosis of choledocholithiasis in a Colombian Caribbean population. Methods: Retrospective cross-sectional study, which included patients with suspected choledocholithiasis, and who were taken for evaluation by ERCP, meeting the criteria proposed by the ASGE of high probability. The result obtained was compared with the presence of choledocholithiasis on ERCP, from which values and 95% confidence intervals were estimated for sensitivity, specificity, positive and negative predictive value, and positive and negative likelihood ratio. Results: A total of 118 patient data were included in this study. The median age of the patients was 46 years (IQR= 31; 17- 89); 78% (n= 92) were female. 65.3% (n= 77) were older than 55 years. The ERCP result was positive in 81.4% (n= 96) of the patients. The presence of an altered liver profile (90%) was found to be the most sensitive test, clinical cholangitis (86%) the most specific, the presence of duct lithiasis by US (85%) was the test with the highest positive predictive value, and the presence of duct lithiasis by US (35%) was the test with the highest negative predictive value. Conclusions: The predictive parameters of the ASGE 2010 criteria for the diagnosis of choledocholithiasis show variability with respect to the performance proposed in the guidelines.
