ABSTRACT The study evaluated the repeatability of the superovulatory response in 12 Australian Merino ewes during the breeding season in one (G1), three (G2), and four (G3) consecutive years. A modified protocol was used based on 200 mg pFSH in eight decreasing doses (12h intervals) and supportive strategies such as changing the CIDR at day 7, spraying the horns with heparinized saline during the procedure, and use of Flunixin Meglumine. No significant differences were found in the total number of structures recovered during the years of application of the superovulation protocol (G1=8±2, G2=18±3, G3=19±4; p>0.05). High repeatability was observed, both for the total number of embryos and for the number of transferable embryos in G2 and G3. Superovulatory treatment for 3 and 4 successive years did not affect the efficacy of embryo retrieval.

RESUMEN El estudio evaluó la repetibilidad de la respuesta superovulatoria en 12 ovejas Merino Australiano durante la estación reproductiva en uno (G1), tres (G2) y cuatro (G3) años consecutivos. Se utilizó un protocolo modificado basado en 200 mg de pFSH en ocho dosis decrecientes (intervalos de 12 h) y estrategias de apoyo tales como el cambio del CIDR al día 7, el rociado de los cuernos durante el procedimiento con solución salina con heparina y el uso de Flunixin Meglumine. No se encontraron diferencias significativas en el número total de estructuras recuperadas durante los años de aplicación del protocolo de superovulación (G1=8±2, G2=18±3, G3=19±4; p>0.05). Se observó una alta repetibilidad, tanto para el número total de embriones como para el número de embriones transferibles en G2 y G3. El tratamiento superovulatorio durante 3 y 4 años sucesivos no afectó la eficacia de la recuperación de embriones.

Abstract Lactic acid bacteria have been studied for their ability to accumulate inorganic selenium, which is reduced to its elemental form or could be integrated into selenoproteins in the form of selenocysteine. This ability to produce bioavailable organic selenium for humans is an advantage that could be exploited in the production of functional foods. In this work, Enterococcus faecium ABMC-05 isolated from a traditional Mexican beverage (tepache) and with NCBI entry number OL413240 was used. Microorganism selenization was performed after the determination of minimal inhibitory concentration of Na2SeO3 (184 mg/L), which was calculated using the graphical method of Talmadge and Fitch. The selenium concentration of accumulated selenium was calculated by inductively coupled plasma optical emission spectroscopy (ICP-OES). The concentration of selenium at 48 h of fermentation was 39.92 mg/L, which represented 23.8% of selenium at medium. This value was consistent with those reported for other lactic acid bacteria. Finally, it was determined the selenocysteine presence in biomass recovery after fermentation using RP-HPLC technique. With these results it was confirmed the biogenic production of selenocysteine by Enterococcus faecium ABMC-05 using an inorganic source.

ABSTRACT Aedes albopictus is considered a potential vector of arboviruses in Colombia. Females and males naturally infected with dengue, Zika and chikungunya viruses have already been found in this country. We document the first record of Ae. albopictus in the Cordoba department, in North of Colombia. The finding was carried out during Ae. aegypti collection activities in the Ayapel, Montelibano, Planeta Rica, Pueblo Nuevo and Puerto Libertador municipalities. The entomological material was collected in water containers such as cement water tanks, tanks, bottles, tires, abandoned toilets, and plastic lids with natural water located in the intradomicile, peridomicile, and extra-domicile spaces of the homes. We collected 658 Ae. albopictus samples in the larva and pupa stages, and once these reached adulthood, we determined that 389 were female and 269 were male. This is the first record of the presence of Ae. albopictus in the Cordoba department.

Abstract Introduction: To describe and analyze the existing perception about job satisfaction (SL) and quality of life (QoL) of Spanish resident doctors in the months which follow the end of the state of alarm due to COVID-19 and one year after that. Method: A Descriptive-correlational study, being the Spanish residents the target population who was asked, using an online form, in two periods (1st from 11/01 to 12/31, 2020 and 2nd between 11/01 and 12/31, 2021). For SL, the Font-Roja questionnaire was used and for QoL, the WHOQOL-BREF (both using a 5-point Likert scale). Results: 404 residents responded (1st cut) and 411 (2nd cut). The results for the global SL showed Rho = 0.09; p = 0.081, without differences between their means (-0.07; p = 0.090). The global QoL, measured through the questionnaire, evinced a low correlation between both cut-offs (Rho = 0.10; p = 0.041), with variations between their means (-0.14; p < 0.001). Conclusions: In relation to SL, no association was revealed between the two periods studied. Regarding QoL, more positive data were found in the 2nd period, both in self-perceived QoL and in the global result of the questionnaire.

Resumen Introducción: Describir y analizar la percepción existente acerca de la satisfacción laboral (SL) y la calidad de vida (CV) de los/las médicos/as residentes españoles/as en los meses posteriores a la terminación del estado de alarma por la COVID-19 y al año de la misma. Método: Estudio descriptivo-correlacional, siendo la población diana los/las residentes españoles/as a quienes se preguntó, mediante formulario online, en dos cortes (1º de 01/11 al 31/12 de 2020 y 2º entre 01/11 y 31/12 de 2021). Para la SL se utilizó el cuestionario Font-Roja y para la CV el WHOQOL-BREF (ambos mediante escala Likert de 5 valores). Resultados: Respondieron 404 residentes (1er corte) y 411 (2º corte). Los resultados para a SL global mostraron Rho = 0,09; p = 0,081, sin diferencias entre sus medias (-0,07; p = 0,090). La CV global, medida a través del cuestionario, indicó baja correlación entre ambos cortes (Rho = 0,10; p = 0,041), con diferencias entre sus medias (-0,14; p < 0,001). Conclusiones: En relación a la SL no se constató asociación entre los dos periodos estudiados. Respecto a la CV se evidenciaron mejores datos, en el 2º corte, tanto en la CV autopercibida como en el resultado global del cuestionario.

Abstract Acute myocarditis is a potentially life-threatening disease in pediatric age, with risk of severe cardiac dysfunction and intracardiac thrombus formation. A previously healthy 16-year-old boy was admitted to the Pediatric Intensive Care Unit with suspicion of acute myocarditis with multiorgan dysfunction. He reported mucous diarrhea, vomiting, and asthenia with one week of evolution. The echocardiogram revealed moderate-to-severe left ventricle dysfunction with mitral and tricuspid regurgitation and two hyperechoic images suggestive of thrombus, later confirmed by cardiac magnetic resonance. Unfractionated heparin was started on admission. Campylobacter jejuni was isolated from feces. Despite treatment, the clinical picture worsened with systemic arterial embolization. Surgical thrombectomy was performed on day 13, and extracorporeal membrane oxygenation (ECMO) was maintained until day 28. At this time, the boy was submitted to orthotopic cardiac transplantation with favorable postoperative course. The therapeutic approach in these cases is controversial and should always be multifactorial and multidisciplinary. Despite the inherent risk of complications, thrombectomy should be considered when conservative approaches fail.

Resumo A miocardite aguda é uma doença potencialmente fatal em idade pediátrica, associada a risco de disfunção cardíaca grave e trombos intracardíacos. Um adolescente de 16 anos de idade, previamente saudável, foi transferido para o Serviço de Medicina Intensiva Pediátrica por suspeita de miocardite aguda com disfunção multiorgânica. Referia diarreia mucosa, vómitos e astenia com uma semana de evolução. O ecocardiograma revelou disfunção ventricular esquerda moderada a grave associada a regurgitação mitral e tricúspide e duas imagens hiperecoicas sugestivas de trombos intracardíacos, posteriormente confirmados por ressonância magnética. Foi iniciada heparina não fracionada. A coprocultura foi positiva para Campylobacter jejuni. Apesar do tratamento, verificou-se agravamento do quadro clínico, com embolização sistémica arterial, sendo submetido a trombectomia no dia 13 e mantido em oxigenação por membrana extracorporal (ECMO) até ao dia 28. Foi realizado transplante cardíaco ortotópico, com boa evolução pós-operatória. A abordagem destes casos é controversa, devendo ser sempre multifatorial e multidisciplinar. Apesar dos riscos inerentes, a trombectomia deve ser considerada quando não se observa uma evolução favorável com abordagens conservadoras.

Abstract Introduction: Fathers have been increasingly involved in the pregnancy and birth of their children, but paternal interventions are still required to relocate the father in his role of co-responsibility in parenting. Objective: To observe the paternal behavior-attitude towards the child and the amount of oxytocin (OT) secreted at birth in parents prepared (in a special way) for childbirth. Method: Pilot study of 8 months, part of a larger qualitative-quantitative research of two phases. The initial qualitative phase developed a male preparatory intervention for the birth, with emphasis on the father-child bonding. The quantitative phase corresponded to the pilot of the antenatal paternal intervention. Results: Fathers actively witnessed the moment of delivery and the mother-child attachment. Subsequently, all of them opted for physical skin-to-skin contact with their child. Paternal OT experienced a (non-significant) increase during father-child contact, compared to baseline OT (immediately after birth). Conclusions: Males prepared, sensitized and involved with their child since pregnancy would experience variations in the amount of OT when they make father-child skin-to-skin contact at childbirth. Experimental research with a larger sample of participants is required to categorically reach a conclusion.

Resumen Introducción: Los padres se han involucrado cada vez más en el embarazo y el nacimiento de sus hijos, pero aún se requieren intervenciones paternas que permitan reubicar al padre en su rol de corresponsabilidad en la crianza. Objetivo: Observar el comportamiento-actitud paterna hacia el/la hijo(a) y la cantidad de oxitocina (OT) secretada en el nacimiento, en padres preparados de un modo especial para el parto. Método: Estudio piloto de 8 meses, parte de una investigación mayor cuali-cuantitativa de dos fases. La fase cualitativa inicial desarrolló una intervención preparatoria de padres para el nacimiento, con énfasis en la vinculación padre-hijo(a). La fase cuantitativa correspondió al piloto de la intervención paterna antenatal. Resultados: Los padres presenciaron activamente el momento del expulsivo y el encuentro madre-hijo(a). Posteriormente, todos optaron por el contacto físico piel-piel con su hijo(a). La OT paterna experimentó un aumento (no significativo) durante el contacto padre-hijo(a) en comparación con la OT basal (momento inmediato al nacimiento). Conclusiones: Padres preparados, sensibilizados y vinculados con su hijo(a) desde el embarazo experimentarían variaciones de la cantidad de OT cuando realizan contacto piel-piel con su hijo(a) en el nacimiento. Se requiere investigación experimental con una muestra mayor de participantes para concluir de manera categórica.

Abstract: The primary objective of this study is to present a theoretical-relational model for basic business principle components from the perspective of internal auditing knowledge management. Data is gathered from different economic sectors by applying a mixed methodological approach that includes a Likert perception variables survey and the Pearson's regression model. The sample is composed of 360 employees in the footwear, leather, and leather goods manufacturing sectors from the city of Bogota (Colombia). The results show that processing control practices are inefficient within productive units due to scarce knowledge on how to perform them. It is concluded that internal audit knowledge management models are insufficient since, usually, the auditor is biased and her/his role is often limited to providing results by analyzing a given evaluation.

Resumen: Este estudio tiene como objetivo proponer un modelo teórico - relacional que aborde los componentes de los principios básicos de las organizaciones vistos desde la gestión del conocimiento en la auditoría interna. Se recurrió a la recolección de información de empresas de diferentes sectores económicos, desde un esquema metodológico mixto, a partir de la modelación matemática de regresión de Pearson, bajo la herramienta de encuestas con variables de percepción de Likert. La población objeto de estudio estuvo constituida por 360 trabajadores del sector productivo del cuero, calzado, marroquinería, talabartería y sus derivados en la ciudad de Bogotá (Colombia). Los resultados muestran que las prácticas del proceso de control son ineficientes dentro de las unidades productivas por el escaso conocimiento de cómo se deben realizar. Se concluye que los modelos de gestión del conocimiento en las auditorías internas son insuficientes, generalmente, se sesga al auditor contratado, y la función suele limitarse a la entrega de resultados mediante un análisis según la evaluación dispuesta.

Resumen INTRODUCCIÓN: La sífilis es una infección de trasmisión sexual adquirida a través de una trasfusión sanguínea, por contacto directo con una lesión activa o por vía vertical. La infección puede trasmitirse al feto en cualquier momento del embarazo. Cada año se registran en el mundo 749,000 casos de sífilis congénita. En México, del 2007 al 2017, se reportaron 1030 casos de sífilis congénita (media de 90.6 casos por año). En 50 a 80% de los casos hay complicaciones materno-fetales. OBJETIVO: Reportar un caso clínico de sífilis congénita temprana, con pénfigo bulloso y descamación al nacimiento. CASO CLÍNICO: Paciente de 25 años, con antecedente de cuatro embarazos, dos partos y un aborto, previamente sana, con control prenatal y pruebas de VDRL y VIH negativas. Los dos últimos embarazos finalizaron con recién nacido, ambos de sexo femenino, con lesiones ampollosas decapitadas, placas blanquecinas de aspecto áspero elevadas sobre una base eritematosa, eritema con descamación gruesa en las manos y pies, y descamación fina generalizada. Ante la sospecha de sífilis congénita se inició la administración de 50,000 UI/kg de penicilina G cristalina por vía intravenosa cada 12 h. La sospecha de sífilis congénita se confirmó. La paciente se dio de alta con citas de seguimiento en la consulta externa. CONCLUSIONES: El control prenatal adecuado, con una o dos pruebas para sífilis, no es suficiente para prevenir la forma congénita. Es necesario el análisis de los casos para encontrar opciones e implementar estrategias de salud pública que prevengan nuevos casos.

Abstract INTRODUCTION: Syphilis is a sexually transmitted infection acquired through blood transfusion, by direct contact with an active lesion or by the vertical route. The infection can be transmitted to the fetus at any time during pregnancy. Each year, 749,000 cases of congenital syphilis are reported worldwide. In Mexico, from 2007 to 2017, 1030 cases of congenital syphilis were reported (average of 90.6 cases per year). In 50 to 80% of cases there are maternal-fetal complications. OBJECTIVE: To report a clinical case of early congenital syphilis with bullous pemphigus and desquamation at birth. CLINICAL CASE: 25-year-old patient, with a history of four pregnancies, two deliveries and one abortion, previously healthy, with prenatal control and negative VDRL and HIV tests. The last two pregnancies ended with a newborn, both female, with decapitated blistering lesions, whitish plaques of rough appearance raised on an erythematous base, erythema with thick desquamation on the hands and feet, and generalized fine desquamation. Suspecting congenital syphilis, 50,000 IU/kg of crystalline penicillin G intravenously every 12 h was started. The suspicion of congenital syphilis was confirmed. The patient was discharged with follow-up outpatient appointments. CONCLUSIONS: Adequate prenatal screening, with one or two tests for syphilis, is not sufficient to prevent the congenital form. Case analysis is necessary to find options and implement public health strategies to prevent new cases.

ABSTRACT The interest in making research more dynamic within universities has evidenced the need for the creation of research groups. In this sense, the purpose of this article is to establish a relationship between the data obtained from bibliometrics and the profile and interest of Architecture Faculty researchers, to identify research niches that guide their work. This research was carried out through a systematic review and use of scientific production bibliometric tools in the last five years within the architecture domain in the SCOPUS database. The research made used five steps that guided the process: search; evaluation; synthesis; analysis; and monitoring. Through the search process, 1,465 scientific documents were obtained, analyzed with the Bibliometrix web application using indicators that allowed obtaining the results, to connect them to both teaching interests and profiles. The analysis identified that sustainability, design, and energy efficiency are topics of interest and constitute trending topics to promote the work and the constitution of research groups.

Abstract Objective: To describe the mental health state of Ecuadorian adults during the COVID-19 pandemic from March to August 2020. Data from a larger study involving several Spanish-speaking countries were analyzed. This research was non-experimental, quantitative, and cross-sectional, conducted through an anonymous online survey used as the collection tool. Results: A total of 766 people participated, 64.23% were women and the mean age was 32.35 (SD = 12.54). Around 8% of the participants declared having presented a diagnosis of COVID-19, and 12.9% having experienced associated symptoms. Most participants (77.4%) indicated not having had mental health problems in the past, and 87.6% did not have these problems during the pandemic. However, 41% acknowledged having experienced greater psychological distress. Participants presented low levels of symptoms of depression, anxiety, and stress. Women and young adults were the most affected groups by the assessed symptoms. Conclusions: In pandemic and confinement situations, providing mental health care services for the general population is essential, especially for women and young adults.

Resumen Objetivo: Describir el estado de la salud mental de los adultos ecuatorianos durante la pandemia por COVID-19 de marzo a agosto de 2020. Para este fin, se analizaron los datos de un estudio más amplio que involucró varios países hispanohablantes. La investigación tuvo un diseño no experimental, cuantitativo, transversal de tipo descriptivo donde se aplicó una encuesta anónima en línea. Resultados: En total participaron 766 personas, 64.23% fueron mujeres y la edad media fue de 32.35 (DT = 12.54). Alrededor del 8% de los participantes declararon haber tenido diagnóstico de COVID-19 y un 12.9% haber experimentado síntomas relacionados. La mayor parte de los participantes (77.4%) indicaron no haber tenido problemas de salud mental en el pasado y el 87.6% no tener estos problemas durante la pandemia. Sin embargo, el 41% reconoció tener mayor malestar psicológico. Los participantes presentaron niveles bajos de síntomas (depresión, ansiedad y estrés).

Conclusiones: En situaciones de confinamiento y pandemia es necesaria la atención de la salud mental de la población general y, en especial, la de las mujeres y los adultos jóvenes.

Abstract Introduction: To describe and analyze the existing perception about the factors related to job satisfaction (LS) and quality of life (QOL) of Spanish resident doctors during the COVID-19 pandemic. Method: Descriptive-correlational study, the target population being the Spanish residents who were asked, using the online form, between 11/01/2020 and 12/31/2020. The Font-Roja questionnaire was used for LS and the WHOQOL-BREF for QOL (both using a 5-value Likert scale). Results: 404 residents responded, without differences by sex (p = 0.269). The LS presented a mean of 2.97 ± 0.04 and the CV of 3.27 ± 0.03. An association was observed in the LS of the first-year residents and the rest (p < 0.001). The LS was not affected by the emergency shifts, but the (QOL) for social relationships (p = 0.042). The relationship between SL and (QOL) was good (Rho = 0.53, p < 0.001). Conclusions: The tutor was a reference for the resident, not the hospital management. No differences were found in relation to sex or duty shifts with the LS. First-year residents presented higher LS and (QOL), which could be due to less responsibility and less accumulated fatigue during the pandemic. The shifts on duty did affect QOL, specifically in social relationships. Poor research training was also compounded by the pandemic.

Resumen Introducción: Describir y analizar la percepción existente acerca de los factores vinculados a la satisfacción laboral (SL) y la calidad de vida (CV) de los médicos residentes españoles durante la pandemia por la COVID-19. Método: Estudio descriptivo-correlacional, siendo la población diana los residentes españoles a los que se preguntó, mediante formulario online, entre el 01/11/2020 y el 31/12/2020.

La SL presentó media de 2,97 ± 0,04 y la CV de 3,27 ± 0,03. Se observó asociación en la SL de los residentes de primer año y el resto (p < 0,001). La SL no se afectó por los turnos de urgencia, pero sí la CV para las relaciones sociales (p = 0,042). La relación entre SL y CV fue buena (Rho = 0,53, p < 0,001). Conclusiones: El tutor fue referente para el residente, no así la dirección del hospital. No se encontraron diferencias en relación al sexo ni a los turnos de guardia con la SL. Los residentes de primer año presentaron mayor SL y CV, pudiendo deberse a su menor responsabilidad y cansancio acumulado durante la pandemia. Los turnos de guardia sí afectaron la CV, específicamente en las relaciones sociales. La escasa formación en investigación se vio asimismo agravada por la pandemia.

ABSTRACT The study of International Relations in Latin America and the Caribbean has been carried out based on the theoretical baggage emanating from the two schools with the greatest preponderance in the scientific discipline: the Anglo-Saxon and the United States. Both present the bases that support Eurocentrism and are the model exported to the rest of the global south. As a consequence of the coloniality of knowledge, the discipline in the region followed the precedents established by Europe to the detriment of its own thinking. Nevertheless, the objective of this article is to show that in the face of this theoretical development there is a turning point in which Latin American thought unleashed a prolific debate that led to the creation of categories and postulates of its own, which constituted a relevant contribution to understanding the international economic structure.

RESUMEN El estudio de las Relaciones Internacionales en América Latina y el Caribe se ha realizado a partir del bagaje teórico emanado de las dos escuelas de mayor preponderancia en la disciplina científica: la anglosajona y la estadounidense. Ambas presentan las bases que sustentan el eurocentrismo y son el modelo exportado al resto del sur global. Como consecuencia de la colonialidad del saber, la disciplina en la región siguió los precedentes establecidos por Europa en detrimento del pensamiento propio. No obstante, el objetivo de este artículo es mostrar que ante ese desarrollo teórico hay un punto de inflexión en el que el pensamiento latinoamericano que desató un prolífero debate que dio lugar a la creación de categorías y postulados propios, los cuales constituyeron una aportación relevante para entender la estructura económica internacional.

Brazil has the greatest plant diversity on the planet, distributed in different types of biomes. These plants are important sources of biologically active natural products, which are derived from various drugs marketed worldwide. This paper presents an electrochemical study of three unusual dimeric flavonoids, pharmacologically active, isolated and identified for the first time by our research group, in a Brazilian plant (Fridericia platyphylla). The results showed that oxidation processes are favored at higher pH, and mass transport was controlled by diffusion. Brachydins derivatives, Bra-A was oxidized at the lowest potential value (0.48 V vs. Ag/AgCl, KCl(sat)) and Bra-B and Bra-C, presented the highest oxidation potentials (ca. 0.71 and ca. 0.57 V vs. Ag/AgCl, KCl(sat), respectively). This study shows that electrochemistry is one more tool that would help us focus on future bio-pharmacological investigations of these unusual compounds.

Abstract: The purpose of this study is to describe how the use of digital manufacturing (DM) by project-based learning (PBL) develops disciplinary competencies linked to the application of this technology. Two tools are used for collecting information: 1) quantitative evaluation of attitudes towards digital manufacturing products and 2) academic practices in behavioral, affective, and cognitive dimensions. The sample is composed of 30 industrial design undergraduate students at the Universidad Javeriana (Colombia). The results show that 80% of the students agreed that incorporating DM to PBL has a positive influence on method design and product development. It is concluded that DM linked to PBL pedagogical strategy is a disruptive learning experience that facilitates students practice in developing a product with freedom and with unrestricted exploration of form and function.

Resumen: El propósito de este estudio es describir cómo el uso de la fabricación digital (FD) incorporada al aprendizaje basado en proyectos (ABP) desarrolla las competencias disciplinares vinculadas a la práctica de esta tecnología. Se utilizan dos herramientas de recolección de información: 1) evaluación cuantitativa de actitudes frente a la FD de un producto, y 2) la práctica académica en las dimensiones conductual, afectiva y cognitiva. La muestra esta compuesta por treinta estudiantes universitarios de diseño industrial de la Universidad Javeriana (Colombia). Los resultados muestran que el 80% de los estudiantes están de acuerdo con que la FD incorporada al ABP influye de manera positiva en el método de diseño y desarrollo de producto. Se concluye que el recurso de la FD articulada a la estrategia pedagógica al ABP, constituye una experiencia de aprendizaje disruptivo que facilita a los estudiantes practicar el desarrollo de un producto con libertad en la exploración irrestricta de la forma y la función.

Abstract Objective: To review the scientific literature related to the effects of occupational exposure to risk factors for skin neoplasms in fishery workers. Method: Critical analysis of the papers recovered through systematic review from en MEDLINE (PubMed), EMBASE, The Cochrane Library, Scopus, Web of Science y Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS). STOROBE guidelines were followed to evaluate their quality. Results: After attributing inclusion and exclusion criteria to the search, 11 articles were accepted for review and critical analysis. In 7 of them, a statistically significant association was obtained between skin neoplasia and occupational exposure in fishermen. Conclusions: Despite having found studies that were significant in terms of the relationship of malignant lesions and exposure to ultraviolet radiation in the workplace, some of them did not control possible biases, therefore the results should be taken with caution.

Resumen Objetivo: Revisar la literatura científica relacionada con los efectos de la exposición ocupacional a factores de riesgo para neoplasias cutáneas en trabajadores del sector pesquero. Método: Análisis crítico de los trabajos recuperados mediante revisión sistemática en MEDLINE (PubMed), EMBASE, The Cochrane Library, Scopus, Web of Science y Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS). Se evaluó la calidad de los artículos seleccionados mediante el cuestionario STROBE. Resultados: Al atribuir los criterios de inclusión y exclusión a la búsqueda, se aceptaron 11 estudios para su revisión. En 7 de ellos, se obtuvo una asociación estadísticamente significativa entre neoplasia cutánea y exposición ocupacional. Conclusiones: Se observa una relación entre lesiones malignas y exposición a radiación ultravioleta en el ámbito laboral, no obstante, la existencia de posibles sesgos hace que los resultados deban de tomarse con precaución.
