RESUMO

BACKGROUND: Abdominal actinomycosis (AA) is a rare infection. The aim of this study was to summarize the evidence available on AA. METHODS: A systematic review was conducted. Data sources included Trip Database, BIREME, SciELO, Cochrane Library, WoS, MEDLINE, EMBASE, SCOPUS, IBECS and LILACS. Eligibility criteria included: studies related to surgically treated AA, in adult population, without language and sex restriction, published between 1966 and 2019. The following variables were analysed: publication year, age, sex, geographical origin, location of lesions, clinical manifestations, risk factors, species isolated and treatments used. RESULTS: A total of 1505 studies were initially identified. After scrutinizing titles and abstracts, and checking duplications, 221 articles including 406 subjects with AA were included. All were case reports or series. Mean age of subjects was 49.2 years and 56.2% were female. The highest proportion of articles was published between 2015 and 2019 (18.7%). Publications were predominantly from the USA (12.2%). Structures usually involved were abdominal wall, colon and appendix. The most common presentation was abdominal mass (39.2%). In 42.1% of patients, an associated factor was found, highlighting intrauterine devices (14.3%). The microbiology studies highlighted Actinomyces israelli. Morbidity, recurrence and verified mortality were 18.2%, 1.0% and 2.2%, respectively. Penicillin was the most used antibiotic. CONCLUSION: Evidence about AA is scarce and dispersed within a reduced range of articles and cases.

RESUMO

El suicidio es un problema de salud a nivel mundial, siendo la conducta suicida uno de los predictores de mortalidad por suicidio; sin embargo, su valoración aún sigue siendo compleja. Aunque la cantidad de literatura que ha abordado distintas perspectivas de la conducta suicida es abundante, se requiere ahondar en nuevos métodos que permitan una valoración rápida y objetiva de ésta, proporcionando a los clínicos y pacientes, un sistema de evaluación que registre los cambios de estados emocionales de manera dinámica. El objetivo de este manuscrito fue proporcionar una visión general de la morfología de los potenciales evocados auditivos de latencia tardía p300 y su rol en la evaluación de la conducta suicida.


Suicide is a global health problem, with suicidal behavior being one of the predictors of suicide mortality; however, its assessment is still complex. Although the amount of literature that has addressed different perspectives of suicidal behavior is abundant, it is necessary to deepen new methods that allow a rapid and objective assessment of it, providing clinicians and patients with an evaluation system that allows changes in emotional state to be recorded dynamically. The aim of this manuscript was to provide an overview of morphological patterns of auditory evoked potential P300 latency late in the assessment of suicidal behavior.

RESUMO

Resumen El objetivo fue identificar las asociaciones entre apoyo social percibido, riesgo suicida y presencia de enfermedad crónica no transmisible en estudiantes universitarios. Utilizando un diseño de casos y controles, con 41 estudiantes universitarios por grupo. La mediana de edad fue de 22 años (R = 9), un 81,8% eran mujeres, el 26,8% de los sujetos tenía Asma y el 26,8% Hipotiroidismo, y el 63,6% pertenecía a la Facultad de Educación. No se comprobó la asociación entre enfermedad crónica, apoyo social, ni tampoco con riesgo suicida. Hay asociación indirecta entre riesgo suicida y apoyo social, no así cuando se evalúa el intento de suicidio previo. El nivel de riesgo suicida y apoyo social se asocian independiente de la presencia de enfermedad crónica. Esperamos que nuestros resultados permitan fomentar el apoyo social como una herramienta fundamental para la prevención de la suicidabilidad, especialmente en sujetos con enfermedad crónica.


Abstract The objective was to identify associations between perceived social support, suicidal risk and the presence of chronic or communicable disease in university students. Using a case-control design, consisting of 41 subjects in each group. The median age was 22 years (R = 9), 81,8% were women, 26,8% of the subjects had asthma and 26,8% had hypothyroidism, 63,6% were students of the faculties of Education. The association between chronic disease and social support was not proven, nor was there a suicidal risk. There is an indirect association between suicide risk and social support, not so when assessing the previous suicide attempt. The levels of suicide risk and social support are associated, independent of an existing chronic disease. We are hopeful that our results will be effective in promoting social support as a basic tool for suicide prevention, especially in subjects with chronic disease.

RESUMO

BACKGROUND: Hepatocellular carcinoma is the most frequent primary tumour of the liver. Although often associated with chronic liver disease, it can also occur in non-cirrhotic livers. The aim of this study was to describe post-operative morbidity (POM), and survival of patients with hepatocellular carcinoma in non-cirrhotic liver treated surgically, and to identify variables associated with prognosis. METHODS: Case series of patients who underwent surgery for hepatocellular carcinoma in non-cirrhotic liver at Clínica RedSalud Mayor de Temuco, Chile (2001-2017), were studied. The minimum follow-up time considered was 12 months. Principal outcomes were development of POM and survival. Other variables of interest were age, sex, tumour diameter, surgical time, hospital stay, follow-up time, need for surgical re-intervention, mortality, vascular and lymph node invasion and staging. Descriptive and analytic statistics were calculated. RESULTS: A total of 32 patients were studied. They were characterized by a mean age of 67.3 ± 7.2 years, 62.5% of whom were men. Averages of tumour diameter, surgical time and hospitalization were 12.0 ± 2.6 cm, 114.4 ± 32.3 min and 7.2 ± 2.9 days, respectively. POM was 31.3%. There was no mortality and there were no re-interventions. The overall actuarial survival at 1, 2 and 3 years was 96.8%, 73.4% and 17.3%, respectively. Lower survival was verified in patients with vascular invasion, lymph node infiltration and stages III and IVa. CONCLUSION: Despite the tumour diameter and extent of the resections, POM in patients with hepatocellular carcinoma in non-cirrhotic liver is moderate. However, its prognosis is poor. Vascular invasion, lymph node invasion and advances stages were associated with worse survival.

RESUMO

La infección por Actinomices (actinomicosis), es una entidad poco frecuente y que puede crear dificultades diagnósticas y terapéuticas; principalmente cuando por su presentación se asemeja a neoplasias malignas. El objetivo de este estudio fue reportar un caso de actinomicosis de pared abdominal con infiltración hepática y revisar la evidencia existente. Se trata de una paciente sexo femenino, de 33 años de edad, sin antecedentes quirúrgicos ni de utilización de dispositivos intra-uterinos. Consultó por dolor abdominal y masa palpable a nivel epigástrico. Se estudió con imágenes, las que permitieron verificar una masa de pared abdominal con trayecto fistuloso al hígado. Se realizó una exéresis amplia de la lesión antes descrita. Una vez extirpado el espécimen, se fue a estudio histopatológico, que reveló gránulos de azufre consistentes con actinomices. La paciente evolució de forma satisfactoria, sin inconvenientes. Presentamos un caso poco común de actinomicosis de pared abdominal con infiltración hepática. Cuando se encuentra una gran masa intraperitoneal, la actinomicosis debe incluirse en el proceso de diagnóstico diferencial.


Actinomyces infection (actinomycosis) may create diagnostic conflicts and be confused with malignant neoplasms, especially in the abdomen. The objective of this study was to report a case of abdominal wall actinomycosis with hepatic infiltration, and review the existing evidence. Female patient, 33 years of age, with no surgical history or use of intra-uterine devices. She consulted for abdominal pain and palpable mass at the epigastrium. It was studied with images, which allowed verifying an abdominal wall mass with hepatic fistulae. A broad extirpation of the lesion was performed. The histological study revealed sulfur granules consistent with actinomyces. The patient has evolved satisfactorily, without problems; and is currently in treatment with amoxicillin. We present an unusual case of abdominal wall actinomycosis with hepatic infiltration that resulted in a difficult diagnosis. When a large intraperitoneal mass is found, actinomycosis needs to be included as a differential diagnoses.

RESUMO

Objective: To describe the results of the extension of surgical treatment and adjuvant chemotherapy (ACT) in incidental gallbladder cancer (CVB), in terms of postoperative morbidity (POM) and 5-year overall survival rate. Method: Case series of patients operated on for incidental GBC in Clínica Mayor, Temuco, Chile (2001-2016). All cases were treated by partial hepatectomy (segments IVb and V), and regional lymphadenectomy. The minimum follow-up time was 12 months. Outcome variables were MPO and 5-year overall survival rate. Other variables of interest were: infiltration depth in vesicular wall, lymph nodes and resected liver; surgical time, need for reoperation, hospital stay, follow-up and mortality. Descriptive statistics were applied as well as bivariate analysis applying Fisher's exact and t-test and non-parametrical tests for continuous variables and Kaplan Meier curves. Results: The series was composed of 50 patients, whose average age was 58.6 ± 9.6 years; 68.0% of which were women. The mean surgical time and hospital stay were 224 ± 93 min (90 to 480) and 6.9 ± 2.9 days (4 to 20), respectively. POM was 28.0%. 5-year overall survival rate was 47%. There were no reoperations or mortality. Conclusions: The results verified in terms of POM and 5-year overall survival rate are similar to previously reported series.

RESUMO

BACKGROUND: Equipoise exists regarding the benefit of adjuvant therapy (AT) in patients with gallbladder cancer (GBC). The aim of this study was to critically review the available evidence for the effectiveness of AT in patients with GBC following surgery with curative intent. METHODS: A systematic review was performed. Relevant studies were identified from Trip Database, BIREME-BVS, SciELO, Cochrane Central Register, WoS, MEDLINE, EMBASE and SCOPUS. Adjuvant therapies considered included chemotherapy, chemoradiotherapy, and radiotherapy. The primary outcome was overall survival (OS). Subgorup analysis of patients with positive lymph node disease (PLND), positive surgical margin (PSM), or advanced stage (AS) were performed. RESULTS: 748 related articles were identified; 27 met the selection criteria (3 systematic reviews and 24 observational studies). Evidence provided was moderate, poor and very poor for chemotherapy, chemoradiotherapy, and radiotherapy. Existing evidence is not robust, but suggests certain benefits with AT in improving OS, especially in patients with PLND, PSM and AS. CONCLUSION: Results do not provide strong evidence that AT is effective in patients who undergo resection for GBC. Subgroups of PLND and PSM may have a survival advantage. Future studies with appropriate internal validity and adequate number of patients are required to better answer this question.

RESUMO

En México la enfermedad renal crónica en la población pediátrica es un grave problema de salud pública. Las alternativas terapéuticas en niños con enfermedad renal crónica (ERC) son la diálisis y el trasplante renal (TxR), siendo esta última, la mejor opción terapéutica actual en niños con estadios terminal de la función renal. El objetivo de este manuscrito, fue reportar nuestra experiencia en el tratamiento perioperatorio de pacientes pediátricos sometidos a trasplante renal en bloque. Paciente de sexo femenino, 12 años de edad, originaria de Veracruz, México. Portadora de ERC estadio IV de KDOQI, secundaria a glomerulopatía. Fue programada para TxR en bloque de donante cadavérico pediátrico; el que se realizó bajo anestesia general balanceada, con ventilación mecánica controlada, isquemia fría de 17 hs, isquemia caliente de 30 min y un tiempo quirúrgico de 5 hs y 10 min. El tiempo anestésico total, fue de 6 hs. La paciente fue trasladada a la Unidad de Terapia Intensiva Pediátrica, con adecuada aceptación del injerto renal. Durante los siguientes siete meses, el curso clínico ha sido satisfactorio, con estudios ecotomográficos renales normales. En esta paciente la glomerulonefritis, le ocasionó que debutara a muy corta edad con una enfermedad renal crónica con terapia sustitutiva de hemodiálisis. El trasplante renal en bloque realizado, fue exitoso debido al manejo multidisciplinario que participa en el programa de trasplante renal


In Mexico, chronic kidney disease is a major public health problem in pediatric patients. The therapeutic options for chronic kidney disease (CKD) in children are dialysis and kidney transplant (KT); the latter constitutes the current treatment of choice for children suffering from end-stage renal disease. The aim of this study was to describe our experience of perioperative treatment of pediatric patients undergoing en bloc kidney transplant. Female patient, 12 years old, from Veracruz, Mexico, suffering from stage 4 CKD according to KDOQI criteria, secondary to glomerulonephritis. An en bloc kidney transplantarion from a pediatric deceased donor was performed; balanced general anesthesia with mechanical ventilation was used. Cold ischemia time was 17 hours and warm ischemia time was 30 minutes. The surgery lasted 5 hours and 10 minutes and the total anesthesia time was 6 hours. The patient was taken to the pediatric intensive care unit and showed an adequate renal graft acceptance. During the following seven months the clinical course was satisfactory and kidney echotomography showed normal results. Glomerulonephritis made this patient undergo hemodialysis replacement therapy due to CKD at a very early age. The en bloc kidney transplantation performed was successful thanks to the multidisciplinary management involved in the Kidney Transplant Program

RESUMO

El lipoma gástrico (LG), es un tumor benigno raro que representa el 5 % de los lipomas gastrointestinales y menos del 1 % de todos los tumores gástricos. Se localizan habitualmente a nivel de la submucosa y generalmente en la región antral. La endoscopia y la tomografía computarizada son las herramientas diagnósticas más utilizadas en el proceso diagnóstico. Dada su relativa rareza, quedan a menudo fuera del diagnóstico diferencial de las masas submucosas gastrointestinales superiores. El objetivo de este manuscrito, es reportar dos casos tratados de forma consecutiva y revisar la literatura existente en esta materia. Se trata de dos pacientes de sexo masculino, de 49 y 69 años de edad, a quienes se diagnosticó una lesión submucosa gástrica por endoscopia y fueron tratados quirúrgicamente y cuyos especímenes fueron estudiados histológicamente, concluyéndose en ambos casos la existencia de un LG. Ambos pacientes evolucionaron de forma correcta y permanecen en controles clínicos y endoscópicos hasta la actualidad, sin inconvenientes. El LG es una entidad poco común, que puede simular una enfermedad maligna. Presentamos dos casos tratados quirúrgicamente con resultados satisfactorios.


Gastric lipoma (GL), is a rare benign tumor that represents 5 % of gastrointestinal lipomas and less than 1 % of all gastric tumors. They are usually located at the level of the submucosa and usually in the antral region. Endoscopy and computed tomography are the diagnostic tools most used in the diagnostic process. Given their relative rarity, they are often left out of the differential diagnosis of the upper gastrointestinal submucosal masses. The aim of this manuscript was to report two cases treated consecutively and review the existing literature on this subject. Two male patients, 49 and 69 years of age, were diagnosed with a gastric submucosal lesion by endoscopy and were treated surgically. The specimens were studied histologically; concluding the existence of a GL in both cases. The two patients evolved adequately and have remained in clinical and endoscopic controls until now, without problems. GL is a rare entity, which can simulate a malignant disease. We present two cases treated surgically with satisfactory results.

RESUMO

La neoplasia papilar intracolecística (NPIC), es un tumor compuesto por células neoplásicas preinvasivas, que forman masas de hasta 1,0 cm, clínicamente detectables. El objetivo de este estudio fue reportar un caso de NPIC y revisar la evidencia existente. Se trata de un paciente sexo masculino, de 33 años de edad, asintomático, que en el curso de un examen de salud, se realiza una ecotomografía abdominal, en la que se verifica una lesión polipoide vesicular de 32 x 19 mm de diámetro. Se programa para colecistectomía electiva, la que se realizó por vía laparoscópica, cirugía que se pudo realizar sin inconvenientes. Una vez extirpado el espécimen, se fue a estudio histopatológico en el que tras un mapeo vesicular se concluye NPIC, colecistitis crónica inespecífica, colesterolosis y pólipos colesterínicos. El paciente ha evolucionado sin inconvenientes. Presentamos un caso de NPIC en un paciente joven, cuyo diagnóstico fue confirmado por anatomía patológica tras una colecistectomía electiva, descartándose la presencia de carcinoma invasivo y displasia de alto grado, por lo que el pronóstico es favorable.


Intracholecystic papillary neoplasm (ICPN) is a tumor composed of pre-invasive neoplastic cells, with up to 1.0 cm clinically detectable masses. The objective of this study was to report a case of NPIC and review the evidence in the literature. A 33-year-old asymptomatic male patient had an abdominal ultrasonography during a health examination, in which a vesicular polyp lesion of 32 x 19 mm in diameter was verified. Thepatient was subsequently scheduled for elective cholecystectomy, which was performed laparoscopically and the surgery was uneventful. Once removed, the specimen was studied histopathologically and after performing vesicular mapping, we determined an ICPN, chronic non-specific cholecystitis, cholesteroliasis and cholesteric polyps. The patient has evolved without reported problems. We present a case of ICPN in a young patient, whose diagnosis was confirmed by pathological anatomy after an elective cholecystectomy, ruling out the presence of invasive carcinoma and high-grade dysplasia, with a favorable prognosis.

RESUMO

La progresivas preocupación de los países para optimizar el acceso, la eficiencia y la calidad de la salud, han impulsado la utilización más apropiada de las intervenciones en salud. Por ende, el interés tanto de profesionales sanitarios como de tomadores de decisiones en salud, ha sido orientado hacia la medicina basada en la evidencia, la eficacia comparativa y la Evaluación de Tecnologías Sanitarias (ETESA). Aunque los conceptos anteriormente señalados son convergentes en sus características, no son sinónimos. Sin embargo, todos estos, se basan en la orientación sistemática de pruebas y el enfoque en resultados relevantes para el paciente entre otras. Como consecuencia de todo esto, el interés no sólo implica los conceptos de eficacia, efectividad y eficiencia; sino que también en práctica clínica, costes y transparencia. En este artículo se resumen los conceptos de economía de la salud, evaluación económica, tecnología sanitaria (TS) y ETESA. Luego, se comenta el ciclo de vida de una TS, razones para implementar un programa de ETESA; para finalizar con algunos ejemplos de TS emergentes, comentarios respecto de la evidencia científica en la ETESA; y algunos ejemplos de estudios de ETESA en la práctica clínica cotidiana.


The progressive concern of countries to optimize access, efficiency and quality of health have led to the most appropriate use of health interventions. Therefore, the interest of both health professionals and health decision makers has been oriented towards evidence-based policy, comparative efficacy and Health Technologies Assessment (HTA). Although the aforementioned concepts are converging in their characteristics, they are not synonymous. However, all these are based on systematic testing orientation and focus on relevant patient outcomes among others. As a consequence of all this, interest does not only imply the concepts of effectiveness, effectiveness and efficiency, but also in clinical practice, costs and transparency.This manuscript summarizes concepts of health economics, economic evaluation, health technology and HTA. Then, the life cycle of a health technology and the reasons for implementing an HTA program are discussed. Concluding with some examples of emerging health technologies, comments on the scientific evidence in HTA, and some examples of HTA studies in daily clinical practice.

RESUMO

Research in diagnostic accuracy studies (DAS) is a rapidly developing area in medicine, but there are only three instruments used in this scenario. The aim of this study was to design and validate a scale to determine methodological quality (MQ) of DAS. Scale validation study. A systematic literature review about the MQ of diagnostic accuracy studies was accomplished, and an expert panel generated a first draft (content validity) of the scale. An alphanumeric order was given and rated by six researchers (second draft) and a pilot study to optimise its use and understanding was performed (third draft). Two independent researchers applied the final scale (9 items/3 domains) to 110 articles from 13 journals with high, medium and low impact factors. Criterion validity was determined by contrasting MQ scores with the Oxford Centre for Evidence-Based Medicine levels of evidence. The construct validity of the extreme groups and high and low IF were estimated. The intraclass correlation coefficient was used to determine inter-observer reliability, and the cut-off point was calculated using a ROC curve. The best cut-off point was 24 points, with an under curve area of 93.4 %. The content validity rating was 80-100 % for all included items. Criterion and construct validity were statistically significant with p<0.05. Interobserver reliability was estimated in 0.96. A scale to measure the MQ of DAS was designed and validated.


La investigación en estudios de precisión diagnóstica (EPD) es un área de rápido desarrollo en medicina, sin embargo, en este escenario sólo existen tres instrumentos. El objetivo de este estudio fue diseñar y validar una escala para determinar calidad metodológica (CM) de EPD. Estudio de validación de escala. Se realizó una extensa revisión de la literatura sobre el CM de EPD y un panel de expertos generó un primer borrador (validez del contenido) de la escala. Se asignó un orden alfanumérico, el que evaluado por 6 investigadores independientes (2º borrador). Posteriormente, se realizó un estudio piloto para optimizar el uso y entendimiento (3º borrador). Dos investigadores independientes aplicaron la escala final (9 ítems / 3 dominios) a 110 artículos de 13 revistas con factores de impacto alto, medio y bajo. Se determinó validez de criterio contrastando puntuaciones de CM con niveles de evidencia del Oxford Centre for Evidence-Based Medicine. Se determinó validez de constructo de grupos extremos (factores de impacto alto y bajo). La confiabilidad interobservador se estimó aplicando coeficiente de correlación intraclase. Finalmente, se evaluaron puntos de corte construyendo curvas ROC. El mejor punto de corte fue 24 puntos (área bajo la curva de 93,4 %). La validez de contenido fue de 80-100 % para todos los elementos incluidos. Validez de criterio y constructo fueron estadísticamente significativos (p<0,05). La confiabilidad interobservador fue de 0,96. Se diseñó y validó una escala para medir el CM de EPD.

RESUMO

Research in methodological quality (MQ) of prognosis studies (PS) is relevant in view of the important number of studies developed in this scenario. However, currently there are no instruments designed to measure MQ in PS, thus the aim of this study was to validate a scale to determine the MQ in PS. Scale validation study. Two independent researchers applied the scale (10 items/4 domains) in 119 articles found in 13 Journals of high, medium and low impact factor. Criterion validity was determined by contrasting MQ scores with Oxford Centre for Evidence-Based Medicine levels of evidence. Construct validity of extreme groups and high and low impact factors were estimated. Intraclass correlation coefficient was used to determine interobserver reliability, and the cut-off point was calculated using a ROC curve. The best cut-off point was 33, with an under curve area of 82.6 %. Criterion and construct validity were statistically significant with (p<0.001). Interobserver reliability was 0.91 and a scale to measure the MQ in PS was validated.


El objetivo de este estudio fue validar una escala para determinar calidad metodológica (CM) de estudios de pronóstico (EP). Se realizó un estudio de validación de escalas. La escala, compuesta por 10 ítems y 4 dominios; se aplicó a 119 artículos de 13 revistas, de factores de impacto alto, medio y bajo; por dos investigadores independientes. La validez del criterio se determinó al contrastar las puntuaciones de CM de cada artículo con los niveles de evidencia del Centro de Medicina Basada en la Evidencia de Oxford de la revista en la cual fueron publicados. Se estimó la validez de constructo de grupos extremos (factores de impacto alto y bajo). Se utilizó el coeficiente de correlación intraclase para determinar la confiabilidad interobservador, y el punto de corte se calculó construyendo curvas ROC. El mejor punto de corte fue 33 puntos (área bajo la curva de 82,6 %). La validez de criterio y de constructo fueron estadísticamente significativas (p<0,001). La confiabilidad interobservador fue 0,91. Se validó una escala para medir CM en EP.

RESUMO

SUMMARY: Ensuring quality in graduate teaching is a guarantee of the competitiveness demonstrated by institutions. The aim of this study was to determine the internal consistency and reliability of the Triple Jump (TJ) instrument applied to Master's and Doctorate students in Medical Sciences to assess compliance of goals. Reliability study conducted at Universidad de La Frontera, Temuco, Chile. TJ was applied by 3 evaluators who performed 2 evaluations, with structured assessment guidelines in three domains (cognitive, attitudinal and procedural), on a Likert scale with scores from 0 (not achieved) to 4 (achieved). The total point score was transformed into a final grade. The evaluated subjects were characterized, and internal consistency and interobserver reliability were determined. Fifty-one Health care professionals enrolled in Medical Sciences graduate programs at the Universidad de La Frontera between 2005-2016 (35 from the Master 's program and 16 from the Doctorate in Medical Sciences). In study subjects had a median age of 29 years, 6 years of professional experience and 3 years as specialists. 66.7 % were male. The internal consistency of the responses to the assessment was characterized by a Cronbach's between 0.734 and 0.938. Interobserver reliability of the instrument had values between 0.86 and 1.0. The levels of internal consistency and reliability were higher than previously reported; therefore, the test is reliable and exhibits solid internal consistency.


RESUMEN: Garantizar la calidad en la enseñanza de posgrado es una garantía de la competitividad demostrada por las instituciones. El objetivo de este estudio fue determinar la consistencia interna y confiabilidad interobservador del instrumento salto triple (ST), aplicado a estudiantes de Magíster y Doctorado en Ciencias Médicas, para evaluar cumplimiento de objetivos de aprendizaje. Estudio de confiabilidad realizado en la Universidad de La Frontera, Temuco, Chile. El ST, fue aplicado por 3 evaluadores que realizaron 2 evaluaciones, utilizando guías de evaluación estructuradas en tres dimensiones (cognitivo, actitudinal y de procedimiento); en una escala tipo Likert con puntajes de 0 (objetivo no logrado) a 4 (objetivo plenamente logrado). El puntaje total se transformó posteriormente en una calificación final. Se caracterizó a los sujetos evaluados y se determinó consistencia interna y confiabilidad interobservador. Para ello, se enrolaron 51 profesionales de la salud matriculados en los programas de postgrado en Ciencias Médicas de la Universidad de La Frontera entre 2005 y 2016 (35 del programa de Magíster y 16 del Doctorado en Ciencias Médicas). Los sujetos a estudio, tenían una mediana de edad de 29 años, 66,7 % eran hombres, tenían 6 años de experiencia profesional y 3 años como especialistas. La consistencia interna de las respuestas a la evaluación se caracterizó por un a de Cronbach entre 0,734 y 0,938. La confiabilidad interobservador del instrumento tenía valores entre 0,86 y 1,0. Los niveles de consistencia interna y confiabilidad fueron más altos que los reportados previamente; por ende, nos parece que esta forma de evaluar objetivos en este tipo de estudiantes, tiene una consistencia interna sólida y es confiable.

RESUMO

Reliability (accuracy, consistency and reproducibility) is a psychometric property, which is related to the absence of measurement error, or, to the degree of consistency and stability of the scores obtained through successive measurement processes with the same instrument. Thus a greater variability of results will lower the accuracy or reliability of instrument used, fact that is transverse from the laboratory to the clinical practice. It is determined by applying the reliability coefficient, which is the correlation between the scores obtained by the subjects in two parallel forms of a test. Assuming that the two forms of the test are parallel (measure the same), the scores of the subjects under study should be the same in both applications. In this way, when the correlation is 1, the reliability or precision is maximum. On the other hand, reliability could be influenced by the observer (the one that measures), the measuring instrument (by that with which it is measured), and by the observed (by what is measured). Therefore, the variability of each of these components must be taken into account when planning the measurement of the variable under study, in such a way to reduce measurement biases as much as possible. The most common ways to determine reliability are the models of parallel forms, test-retest and two halves. This manuscript focuses on the concepts of measurement and the various statistical techniques used for this, as a step prior to application in the clinic. Therefore, the aim of this manuscript is to generate a consultation document related to the reliability or reproducibility of the measurement process.

RESUMO

Resumen En investigación, la confiabilidad (precisión, consistencia y reproducibilidad), corresponde a una propiedad psicométrica que dice relación con la ausencia de error de la medición; o del grado de consistencia y estabilidad de las puntuaciones obtenidas a lo largo de sucesivos procesos de medición con un mismo instrumento. Por ello, es esperable que, a mayor variabilidad de resultados, menor sea la precisión del instrumento de medición utilizado, concepto que aplica desde el laboratorio a la práctica clínica. La reproducibilidad se determina aplicando el coeficiente de confiabilidad, que es la correlación entre las puntuaciones obtenidas por los sujetos, en dos formas paralelas de una prueba (porque se supone que miden lo mismo). Por ello, asumiendo que midan lo mismo, las puntuaciones de los sujetos en estudio deberían ser iguales en ambas aplicaciones. De este modo, cuando la correlación es 1, la confiabilidad, precisión o reproducibilidad es máxima; y mientras más cercana a 0 es peor. La precisión en las mediciones está influenciada por el que mide (observador), por aquello con lo que se mide (instrumento de medición), y por lo que es medido (lo observado). Por ende, se ha de tomar en cuenta la variabilidad de cada uno de estos componentes al momento de planificar la medición de la variable en estudio; de tal modo de reducir al máximo los sesgos de medición. Así, las formas más comunes de determinar confiabilidad son: modelos de formas paralelas, test-retest y de dos mitades. Este manuscrito se centra en los conceptos de medición y las diversas técnicas estadísticas utilizadas para ello, como paso previo a la aplicación en la clínica. Por ello, el objetivo de este manuscrito es generar un documento de estudio y consulta relacionado con la confiabilidad, reproducibilidad o precisión del proceso de medición.

RESUMO

Las publicaciones relacionadas con morbilidad postoperatoria en hidatidosis hepática son escasas y de resultados disímiles. El objetivo de este estudio fue determinar factores de riesgo y protectores de morbilidad postoperatoria en pacientes intervenidos por hidatidosis hepática. Se realizó una revisión global de la evidencia, basada en revisiones sistemáticas, ensayos clínicos y estudios observacionales, obtenidos de Trip Database, BVS, SciELO, Cochrane Central Register of Controlled Trials, WoS, MEDLINE, EMBASE, SCOPUS, EBSCOhost, IBECS, ePORTUGUESe, LILACS y WHOLIS. Se identificaron 1.087 artículos relacionados y 69 cumplían criterios de selección (2 revisiones sistemáticas, 3 ensayos clínicos y 64 estudios observacionales). Se identificaron como factores de riesgo la edad, el antecedente de cirugía previa por hidatidosis hepática, la localización centro hepática, la existencia de comunicaciones biliares y complicaciones evolutivas del quiste y como protectores las técnicas quirúrgicas radicales. Se identificaron factores de riesgo y protectores; sin embargo, los estudios son escasos y de calidad moderada a baja (AU)


There are few publications related to postoperative morbidity in hepatic hydatidosis and these have mixed results. The aim of this study was to determine risk and protective factors of postoperative morbidity in patients operated on for hepatic hydatidosis. A comprehensive review was made of the evidence, based on systematic reviews, clinical analyses and observational studies, obtained from the Trip Database, BVS, SciELO, Cochrane Central Register of Controlled Trials, WoS, MEDLINE, EMBASE, SCOPUS, EBSCOhost, IBECS, ePORTUGUESe, LILACS and WHOLIS. 1,087 related articles were identified; 69 fulfilled the selection criteria (2 systematic reviews, 3 clinical trials and 64 observational studies). Age, history of previous surgery for hepatic hydatidosis, location in the hepatic center, existence of biliary communications and evolutionary complications of the cyst were identified as risk factors, and radical surgical techniques as protective factors. Risk and protective factors were identified; however, the studies are few and the quality moderate to low (AU)
