Exploring the potential of omics technologies in medicinal plant research: a review in Colombia / Explorando el potencial de las tecnologías ómicas en la investigación de plantas medicinales: una revisión en Colombia

This review presents advances in the implementation of high - throughput se quencing and its application to the knowledge of medicinal plants. We conducted a bibliographic search of papers published in PubMed, Science Direct, Google Scholar, Scopus, and Web of Science databases and analyzed the obtained data using VOSviewer (versi on 1.6.19). Given that medicinal plants are a source of specialized metabolites with immense therapeutic values and important pharmacological properties, plant researchers around the world have turned their attention toward them and have begun to examine t hem widely. Recent advances in sequencing technologies have reduced cost and time demands and accelerated medicinal plant research. Such research leverages full genome sequencing, as well as RNA (ribonucleic acid) sequencing and the analysis of the transcr iptome, to identify molecular markers of species and functional genes that control key biological traits, as well as to understand the biosynthetic pathways of bioactive metabolites and regulatory mechanisms of environmental responses. As such, the omics ( e.g., transcriptomics, metabolomics, proteomics, and genomics, among others) have been widely applied within the study of medicinal plants, although their usage in Colombia is still few and, in some areas, scarce.

Public health surveillance and the data, information, knowledge, intelligence and wisdom paradigm / Vigilancia de salud pública y el paradigma de datos, información, conocimiento, inteligencia y sabiduría / Vigilância em saúde pública e o paradigma de dados, informações, conhecimento, inteligência e sabedoria

ABSTRACT This article points out deficiencies in present-day definitions of public health surveillance, which include data collection, analysis, interpretation and dissemination, but not public health action. Controlling a public health problem of concern requires a public health response that goes beyond information dissemination. It is undesirable to have public health divided into data generation processes (public health surveillance) and data use processes (public health response), managed by two separate groups (surveillance experts and policy-makers). It is time to rethink the need to modernize the definition of public health surveillance, inspired by the authors' enhanced Data, Information, Knowledge, Intelligence and Wisdom model. Our recommendations include expanding the scope of public health surveillance beyond information dissemination to comprise actionable knowledge (intelligence); mandating surveillance experts to assist policy-makers in making evidence-informed decisions; encouraging surveillance experts to become policy-makers; and incorporating public health literacy training - from data to knowledge to wisdom - into the curricula for all public health professionals. Work on modernizing the scope and definition of public health surveillance will be a good starting point.

RESUMEN En este artículo se señalan las deficiencias de las definiciones actuales de la vigilancia de salud pública, que incluyen la recopilación, el análisis, la interpretación y la difusión de los datos, pero no las medidas de salud pública. El control de un problema de salud pública de interés exige una respuesta de salud pública que vaya más allá de la difusión de información. No es deseable que la salud pública esté dividida por un lado en procesos de generación de datos (vigilancia de salud pública) y por otro en procesos de uso de datos (respuesta de salud pública), gestionados por dos grupos diferentes (expertos en vigilancia y responsables de la formulación de políticas). Ha llegado el momento de replantear la necesidad de modernizar la definición de la vigilancia de salud pública tomando como referencia el modelo mejorado de Datos, Información, Conocimiento, Inteligencia y Sabiduría de los autores. Entre las recomendaciones que se proponen se encuentran las de ampliar el alcance de la vigilancia de salud pública más allá de la difusión de información para que incluya también el conocimiento aplicable (inteligencia); instar a los expertos en vigilancia a que presten ayuda a los responsables de la formulación de políticas en la toma de decisiones basadas en la evidencia; alentar a los expertos en vigilancia a que se conviertan en responsables de la formulación de políticas; e incorporar la formación en conocimientos básicos de salud pública (desde los datos hasta los conocimientos y la sabiduría) en los planes de estudio de todos los profesionales de la salud pública. Un buen punto de partida será trabajar en la modernización del alcance y la definición de la vigilancia de salud pública.

RESUMO Este artigo aponta deficiências nas definições atuais de vigilância em saúde pública, que incluem coleta, análise, interpretação e disseminação de dados, mas não ações de saúde pública. O controle de um problema preocupante de saúde pública exige uma resposta de saúde pública que vá além da disseminação de informações. A saúde pública não deve ser dividida em processos de geração de dados (vigilância em saúde pública) e processos de uso de dados (resposta de saúde pública) gerenciados por dois grupos distintos (especialistas em vigilância e formuladores de políticas). É hora de repensar a necessidade de modernizar a definição de vigilância em saúde pública, inspirada no modelo aprimorado de Dados, Informações, Conhecimento, Inteligência e Sabedoria dos autores. Nossas recomendações incluem: expansão do escopo da vigilância em saúde pública para além da disseminação de informações, de modo a abranger conhecimentos acionáveis (inteligência); obrigatoriedade de que os especialistas em vigilância auxiliem os formuladores de políticas na tomada de decisões baseadas em evidências; incentivo para que os especialistas em vigilância se tornem formuladores de políticas; e incorporação de capacitação em letramento em saúde pública (partindo dos dados para o conhecimento e em seguida para a sabedoria) nos currículos de todos os profissionais de saúde pública. O trabalho de modernizar o escopo e a definição de vigilância em saúde pública será um bom ponto de partida.

Guía colombiana de tuberculosis genitourinaria / Colombian clinical practice guideline for urogenital tuberculosis

Objetivo: Brindar recomendaciones actualizadas en el diagnóstico, así como en el tratamiento médico y quirúrgico, para urólogos y profesionales de la salud atendiendo pacientes con tuberculosis genitourinaria. Método: Revisión sistemática de la literatura sobre tuberculosis urogenital definiendo preguntas de trabajo con esquema PICO para temas como epidemiología, fisiopatología, diagnóstico, manejo médico y quirúrgico de la enfermedad, y secuelas. Resultados: La tuberculosis genitourinaria presenta una incidencia aproximada del 20%, aunque se estima que hay subregistro importante. En Colombia, la tuberculosis es endémica, pero no hay guías para el diagnóstico y el manejo de este compromiso urogenital, por lo que son una necesidad. La tuberculosis genitourinaria debe sospecharse en pacientes con cuadros inflamatorios o infecciosos urinarios recurrentes, con o sin alteración estructural del tracto genitourinario, sin respuesta al tratamiento farmacológico convencional, sin causa clara o con nexo y factor de riesgo epidemiológico identificado. Puede diagnosticarse por medio de pruebas bacteriológicas, serológicas, moleculares o histopatológicas. En cada caso se requiere una evaluación imagenológica adecuada para determinar el compromiso orgánico o las secuelas, así como la estrategia para el manejo quirúrgico. Conclusiones: La tuberculosis genitourinaria es una condición infectocontagiosa, problema de salud pública, que concierne con gran interés a Colombia. Puede afectar cualquier órgano del tracto genitourinario femenino y masculino. El tratamiento médico oportuno tiene los mejores resultados y las menores tasas de necesidad quirúrgica y de secuelas. El abordaje diagnóstico y terapéutico estandarizado busca mejorar los resultados clínicos, la calidad de vida y la oportunidad del paciente con sospecha de esta enfermedad.

Objective: To provide updated recommendations in diagnosis, as well as for medical and surgical treatment focused on urologists and health-care professionals participating actively in care for urogenital tuberculosis. Method: Systematic review of literature on urogenital tuberculosis, previously defining working clinical questions with PICO scheme for topics such as epidemiology, pathophysiology, diagnosis, medical and surgical therapeutics for the disease. Results: Genitourinary tuberculosis has an incidence of approximately 20%, although a significant underreporting is estimated. In Colombia, tuberculosis infection is endemic, but there are no guidelines focused on this urogenital involvement, so there is a necessity. Urogenital tuberculosis should be suspected in patients with recurrent urinary inflammatory or infectious conditions, with or without structural alterations of genitourinary tract, who do not respond to conventional pharmacological treatment, with no apparent cause or have identified epidemiological link and risk factors. Diagnosis can be made by serological, bacteriological, molecular tests or histopathology. In each case, adequate imaging evaluation is mandatory to determine organ involvement, sequelae, and as strategy for surgical treatment. Conclusions: Genitourinary tuberculosis is an infectious disease, a public health issue, which concerns Colombia. It can affects any female and male urogenital tract organic tissue. Timely pharmacological management offers and has the best clinical results and lowest rates of surgical need or sequelae. The standardized diagnostic and therapeutic approach seeks to improve clinical outcomes, quality of life and opportunity for patients with suspected disease.

Firefighting and Cancer: A Meta-analysis of Cohort Studies in the Context of Cancer Hazard Identification

Objective@#We performed a meta-analysis of epidemiological results for the association between occupational exposure as a firefighter and cancer as part of the broader evidence synthesis work of the IARC Monographs program. @*Methods@#A systematic literature search was conducted to identify cohort studies of firefighters followed for cancer incidence and mortality. Studies were evaluated for the influence of key biases on results. Random-effects meta-analysis models were used to estimate the association between ever-employment and duration of employment as a firefighter and risk of 12 selected cancers. The impact of bias was explored in sensitivity analyses. @*Results@#Among the 16 included cancer incidence studies, the estimated meta-rate ratio, 95% confidence interval (CI), and heterogeneity statistic (I2) for ever-employment as a career firefighter compared mostly to general populations were 1.58 (1.14–2.20, 8%) for mesothelioma, 1.16 (1.08–1.26, 0%) for bladder cancer, 1.21 (1.12–1.32, 81%) for prostate cancer, 1.37 (1.03–1.82, 56%) for testicular cancer, 1.19 (1.07–1.32, 37%) for colon cancer, 1.36 (1.15–1.62, 83%) for melanoma, 1.12 (1.01–1.25, 0%) for non-Hodgkin lymphoma, 1.28 (1.02–1.61, 40%) for thyroid cancer, and 1.09 (0.92–1.29, 55%) for kidney cancer. Ever-employment as a firefighter was not positively associated with lung, nervous system, or stomach cancer. Results for mesothelioma and bladder cancer exhibited low heterogeneity and were largely robust across sensitivity analyses. @*Conclusions@#There is epidemiological evidence to support a causal relationship between occupational exposure as a firefighter and certain cancers. Challenges persist in the body of evidence related to the quality of exposure assessment, confounding, and medical surveillance bias.

Evaluation of the reproducibility of the Tronzo classification for intertrochanteric fractures of the femur in an orthopedic service of a Hospital in Ibagué, Colombia / Evaluación de la reproducibilidad de la clasificación de Tronzo para fracturas intertrocantéricas de fémur en un servicio de ortopedia de un Hospital de Ibague, Colombia

Introduction: Hip fractures are a pathology of traumatic origin that generates a high impact on public health. The objective is to evaluate the interobserver reproducibility of the Tronzo classification for intertrochanteric fractures. Methods: Observational, analytical and retrospective study carried out in Ibagué - Colombia, 48 hip radiographs were analyzed, classified by 10 observed among specialists and training personnel, using the Tronzo classification. Interobserver reproducibility is assessed using the kappa concordance coefficient. Results: Among all those observed in the study, there is greater agreement in the identification of intertrochanteric fractures of lesser and greater severity (Tronzo I and V), the main exponents of this agreement are the most experienced staff, the staff in training, with intermediate experience they agree when identifying those of intermediate severity and for those with less experience the concordance becomes evident when evaluating the intermediate grades. Conclusion: The concordance increases with the experience for the identification of the types with high complexity. This classification is not suitable for clinical practice, another system is necessary for this type of fracture in clinical conduct.

Introducción: Las fracturas de cadera son una patología de origen traumático que genera un alto impacto en la salud pública. El objetivo es evaluar la reproducibilidad interobservador de la clasificación de Tronzo para fracturas intertrocantéricas. Métodos: Estudio observacional, analítico y retrospectivo realizado en Ibagué ­ Colombia, se analizaron 48 radiografías de cadera, clasificadas por 10 observado entre especialistas y personal en formación, utilizando la clasificación de Tronzo. La reproducibilidad interobservador se evalúa mediante el coeficiente de concordancia kappa. Resultados: Entre todos los observados del estudio existe mayor acuerdo en la identificación de fracturas intertrocantéricas de menor y mayor gravedad (Tronzo I y V), los principales exponentes de este acuerdo son el personal de mayor experiencia, el personal en formación, con experiencia intermedia están de acuerdo al identificar a los de gravedad intermedia y para los que tienen menos experiencia la concordancia se hace evidente a la hora de evaluar los grados intermedios. Conclusión: La concordancia aumenta con la experiencia para la identificación de los tipos con alta complejidad. No es adecuado para la práctica clínica esta clasificación, es necesario otro sistema para este tipo de fracturas en las conductas clínicas.

Síndrome neuroléptico maligno asociado con intoxicación aguda por un organofosforado: reporte de caso / Neuroleptic malignant syndrome associated with acute organophosphate poisoning: Case report

El síndrome neuroléptico maligno es una condición clínica rara y potencialmente letal que frecuentemente se asocia con el uso de antipsicóticos. En la literatura especializada se encontró únicamente un reporte de caso relacionado con la ingestión de organofosforados. Se presenta un paciente con un cuadro clínico correspondiente al síndrome neuroléptico maligno posterior a la ingestión de clorpirifós. Como resultado de un intento de suicidio con el mencionado organofosforado, el hombre de 57 años presentó deterioro agudo del estado de consciencia, evolución neurológica tórpida e inestabilidad autonómica asociada a rigidez e hipertermia persistentes, así como incremento de la creatina-fosfocinasa (creatine phosphokinase, CPK). Se le administró tratamiento con bromocriptina, con lo cual el cuadro clínico remitió, y fue dado de alta sin secuelas. El diagnóstico del síndrome neuroléptico maligno es clínico y debe contemplarse en cualquier caso de exposición a sustancias que puedan resultar en una desregulación de la neurotransmisión dopaminérgica, con el fin de iniciar el tratamiento oportuno y contrarrestar efectivamente los efectos.

Neuroleptic malignant syndrome is a rare and potentially fatal clinical condition frequently associated with the use of antipsychotics. In the literature, there is only one case report associated with the intake of organophosphates. We present the case of a patient who presented with a clinical picture compatible with neuroleptic malignant syndrome, after the ingestion of an organophosphate (chlorpyrifos). A 57-year-old man who consulted for attempted suicide, acute deterioration of consciousness, torpid neurological evolution, and associated autonomic instability associated with rigidity, persistent hyperthermia, and elevated CPK. Bromocriptine treatment was offered, which resolved the clinical picture. The association with the ingestion of an organophosphate was established, and he was discharged without sequelae. The diagnosis of neuroleptic malignant syndrome is clinical and should be considered in any case of exposure to substances that may lead to dysregulation of dopaminergic neurotransmission in order to initiate timely therapy and impact outcomes.

Implementação Clínica de Diferentes Estratégias para Reabilitação Baseada em Exercícios em Receptores de Transplante de Rim e Fígado: Um Estudo Piloto / Clinical Implementation of Different Strategies for Exercise-Based Rehabilitation in Kidney and Liver Transplant Recipients: A Pilot Study

Resumo Fundamento: A doença cardiovascular está entre as principais causas de morte entre pacientes transplantados. Embora esses pacientes possam teoricamente se beneficiar de programas de reabilitação baseada em exercícios (RBE), sua implementação ainda é um desafio. Objetivo: Apresentamos nossa experiência inicial em diferentes modos de realização de um programa piloto de RBE em receptores de transplante de rim e fígado. Métodos: Trinta e dois pacientes transplantados renais ou hepáticos foram convidados para um programa de RBE de 6 meses realizado na academia do hospital, na academia comunitária ou em casa, de acordo com a preferência do paciente. O nível de significância adotado foi de 5%. Resultados: Dez pacientes (31%) não completaram o programa. Entre os 22 que completaram, 7 treinaram na academia do hospital, 7 na academia comunitária e 8 em casa. O efeito geral foi um aumento de 11,4% nos METs máximos (tamanho do efeito de Hedges g = 0,39). O grupo de academia hospitalar teve um aumento nos METs de 25,5% (g = 0,58, tamanho de efeito médio) versus 10% (g = 0,25) e 6,5% (g = 0,20) para os grupos de academia comunitária e em casa, respectivamente. Houve efeito benéfico nas pressões arteriais sistólica e diastólica, maior para os grupos academia hospitalar (g= 0,51 e 0,40) e academia comunitária (g= 0,60 e 1,15) do que para os pacientes treinando em casa (g= 0,07 e 0,10). Nenhum evento adverso significativo foi relatado durante o seguimento. Conclusão: Programas de RBE em receptores de transplante de rim e fígado devem ser incentivados, mesmo que sejam realizados fora da academia do hospital, pois são seguros com efeitos positivos na capacidade de exercício e nos fatores de risco cardiovascular.

Abstract Background: Cardiovascular disease is among the leading causes of death in solid organ transplant recipients with a functional graft. Although these patients could theoretically benefit from exercise-based rehabilitation (EBR) programs, their implementation is a challenge. Objective: We present our initial experience on different delivery modes of a pilot EBR program in kidney and liver transplant recipients. Methods: Thirty-two kidney or liver transplant recipients were invited for a 6-month EBR program delivered at the hospital gym, community gym or at home, according to the patient's preference. The significance level adopted was 5%. Results: Ten patients (31%) did not complete their program. Among the 22 who did, 7 trained at the hospital gym, 7 at the community gym, and 8 at home. The overall effect was an 11.4% increase in maximum METs (Hedges' effect size g = 0.39). The hospital gym group had an increase in METs of 25.5% (g= 0.58, medium effect size) versus 10% (g= 0.25), and 6.5% (g= 0.20) for the community gym and home groups, respectively. There was a beneficial effect on systolic and diastolic blood pressures, greater for the hospital gym (g= 0.51 and 0.40) and community gym (g= 0.60 and 1.15) groups than for the patients training at home (g= 0.07 and 0.10). No significant adverse event was reported during the follow-up. Conclusion: EBR programs in kidney and liver transplant recipients should be encouraged, even if they are delivered outside a hospital gym, since they are safe with positive effects on exercise capacity and cardiovascular risk factors.

Embarazo con miomatosis uterina complicado con isquemia intestinal: reporte de un caso / Pregnancy with uterine myomatosis complicated by intestinal ischemia: case report

Resumen Los miomas uterinos, también conocidos como fibromas o leiomiomas, son los tumores uterinos benignos más prevalentes. Afectan a las mujeres principalmente durante sus años reproductivos y se diagnostican hasta en un 70% de las mujeres blancas y en más del 80% de las mujeres de ascendencia africana durante su vida, con una prevalencia durante el embarazo del 2% al 10%. Pueden ser asintomáticos hasta en un 70% de las pacientes, y se estima que pueden ocurrir complicaciones en aproximadamente una de cada 10 mujeres embarazadas. Se han asociado a complicaciones y resultados adversos del embarazo, según su tamaño y ubicación en el útero, y pueden manifestarse de diferentes formas. Presentamos el caso de una mujer de 30 años, con embarazo en el tercer trimestre, quien consultó por dolor abdominal, con ecografías obstétricas durante su control prenatal que reportaban miomatosis uterina, quien presentó isquemia intestinal por un vólvulo de intestino delgado versus compresión extrínseca.

Abstract Uterine fibroids, also known as fibroids or leiomyomas, are the most prevalent benign uterine tumors, affecting women mainly during their reproductive years and are diagnosed in up to 70% of white women and more than 80% of women of African descent during their lifetime, with a prevalence during pregnancy of 2% to 10%; they may be asymptomatic in up to 70% of patients, and it is estimated that complications may occur in approximately one in 10 pregnant women. They have been associated with complications and adverse pregnancy outcomes, depending on their size and location in the uterus, they can manifest in different ways. We present the case of a 30-year-old woman, pregnant in the third trimester, who consulted for abdominal pain, with obstetric ultrasound scans during her prenatal check-up reporting uterine myomatosis, who presented intestinal ischemia due to small bowel volvulus versus extrinsic compression.

Guía atrapada durante cambio de electrodo del seno coronario en terapia de resincronización cardiaca / Trapped guidewire during coronary sinus electrode exchange in cardiac resynchronization therapy

Resumen Se presenta el caso de una paciente con atrapamiento de guía al interior del seno coronario durante el procedimiento de cambio de un electrodo (Sentus ProMRI OTW BP L-85) por desalojo asociado a disfunción de la terapia de resincronización cardiaca. Durante el implante del nuevo electrodo se presentó atrapamiento y retención intravascular de la guía utilizada para su posicionamiento a nivel del seno coronario, lo cual hizo imposible su remoción. La paciente no aceptó tratamiento quirúrgico, se encuentra en vigilancia médica y permanece asintomática desde hace 3 años.

Abstract It is reported the case of a patient with guidewire trapping inside the coronary sinus during an electrode exchange procedure (Sentus ProMRI OTW BP L-85) due to dislocation associated with dysfunction of cardiac re-synchronization therapy. During the implantation of the new electrode, entrapment of the guidewire used for its positioning at the level of the coronary sinus and intravascular retention were presented, making it impossible to remove it. The patient did not accept surgical treatment and has been under medical surveillance, asymptomatic for three years.

Immune characterization of a Colombian family cluster with SARS-CoV-2 infection / Caracterización inmunológica de un grupo familiar colombiano con infección por SARS-CoV-2

Abstract | Introduction: Immunological markers have been described during COVID-19 and persist after recovery. These immune markers are associated with clinical features among SARS- CoV-2 infected individuals. Nevertheless, studies reporting a comprehensive analysis of the immune changes occurring during SARS-CoV-2 infection are still limited. Objective: To evaluate the production of proinflammatory cytokines, the antibody response, and the phenotype and function of NK cells and T cells in a Colombian family cluster with SARS-CoV-2 infection. Materials and methods: Proinflammatory cytokines were evaluated by RT-PCR and ELISA. The frequency, phenotype, and function of NK cells (cocultures with K562 cells) and T-cells (stimulated with spike/RdRp peptides) were assessed by flow cytometry. Anti-SARS-CoV-2 antibodies were determined using indirect immunofluorescence and plaque reduction neutralization assay. Results: During COVID-19, we observed a high proinflammatory-cytokine production and a reduced CD56bright-NK cell and cytotoxic response. Compared with healthy controls, infected individuals had a higher frequency of dysfunctional CD8+ T cells CD38+HLA-DR-. During the acute phase, CD8+ T cells stimulated with viral peptides exhibited a monofunctional response characterized by high IL-10 production. However, during recovery, we observed a bifunctional response characterized by the co-expression of CD107a and granzyme B or perforin. Conclusion: Although the proinflammatory response is a hallmark of SARS-CoV-2 infection, other phenotypic and functional alterations in NK cells and CD8+ T cells could be associated with the outcome of COVID-19. However, additional studies are required to understand these alterations and to guide future immunotherapy strategies.

Resumen | Introducción. Se han descrito diferentes marcadores inmunológicos durante la COVID-19, los cuales persisten incluso después de la convalecencia y se asocian con los estadios clínicos de la infección. Sin embargo, aún son pocos los estudios orientados al análisis exhaustivo de las alteraciones del sistema inmunológico en el curso de la infección. Objetivo. Evaluar la producción de citocinas proinflamatorias, la reacción de anticuerpos, y el fenotipo y la función de las células NK y los linfocitos T en una familia colombiana con infección por SARS-CoV-2. Materiales y métodos. Se evaluaron las citocinas proinflamatorias mediante RT-PCR y ELISA; la frecuencia, el fenotipo y la función de las células NK (en cocultivos con células K562) y linfocitos T CD8+ (estimulados con péptidos spike/RdRp) mediante citometría de flujo, y los anticuerpos anti-SARS-CoV-2, mediante inmunofluorescencia indirecta y prueba de neutralización por reducción de placa. Resultados. Durante la COVID-19 hubo una producción elevada de citocinas proinflamatorias, con disminución de las células NK CD56 bright y reacción citotóxica. Comparados con los controles sanos, los individuos infectados presentaron con gran frecuencia linfocitos T CD8+ disfuncionales CD38+HLA-DR-. Además, en los linfocitos T CD8+ estimulados con péptidos virales, predominó una reacción monofuncional con gran producción de IL-10 durante la fase aguda y una reacción bifuncional caracterizada por la coexpresión de CD107a y granzima B o perforina durante la convalecencia. Conclusión. Aunque la reacción inflamatoria caracteriza la infección por SARS-CoV-2, hay otras alteraciones fenotípicas y funcionales en células NK y linfocitos T CD8+ que podrían asociarse con la progresión de la infección. Se requieren estudios adicionales para entender estas alteraciones y guiar futuras estrategias de inmunoterapia.

Perception of Causes of Repetition Amongst Dentistry Students A Novel Experience with Content Analysis

ABSTRACT: To determine the perception of fourth-year dentistry students at a private Chilean university, regarding the causes of their course repetition. Open-ended questions were asked to 14 repeating students. The resulting narratives went through content analysis using QDA Miner Lite software. The category "non-fullfilment with clinical requirements" had the highest frequency of appearance (52.0 %). Codes with the highest frequency of appearance were "Lacked of time" (24.0%); "Lack of proper organization of time/patient's agenda" (18.0 %) and "Lack of knowledge of the clinical dynamics" (16.0%). The tardiness and repeated absences of the patients were mentioned as the greatest difficulty faced by the students (18.0 %). Students perceive the reasons behind their repetition, differently. However aspects associated with compliance of clinical requirements and patients management are recurring issues. Content analysis is a useful tool for acquiring and analyzing data of complex phenomena as perspectives on university repetition among higher-level dentistry students.

RESUMEN: El objetivo del estudio fue determinar la percepción de los estudiantes de cuarto año de odontología en una universidad chilena, con respecto a las causas de su repetición académica. Se realizaron preguntas abiertas a 14 estudiantes repitentes del cuarto año de la carrera de Odontología. Se desarrolló el análisis de contenido de los relatos de los participantes con el software QDA Miner Lite. La categoría "incumplimiento de requisitos clínicos" obtuvo la mayor frecuencia de aparición entre los relatos (52.0 %). Los códigos con mayor frecuencia de aparición son "faltó tiempo" (24.0 %); "mal manejo y organización de mi tiempo y el del paciente" (18.0 %) y "faltó conocimiento de la dinámica de la asignatura" (16.0 %). Como anexo, la impuntualidad y ausencias reiteradas de los pacientes, fueron mencionadas como la mayor dificultad enfrentada por los estudiantes (18.0 %). Los estudiantes perciben de manera heterogénea las razones detrás de su repetición académica, sin embargo aspectos asociados al cumplimiento de los requisitos clínicos y el trato con los pacientes, son reiterativos en los relatos. El análisis de contenido es una herramienta útil para adquirir y analizar fenómenos complejos, tal como la percepción sobre la repetición universitaria en años superiores de Odontología.

Breeding biology in a population of Rufous-collared Sparrow (Zonotrichia capensis, Statius Müller, 1776) at different elevations in the Tropical Andes / Biología reproductiva en una población de Gorrión Copetón (Zonotrichia capensis, Statius Müller, 1776) a diferente elevación en los Andes tropicales

Abstract: Breeding biology in a population of Rufous-collared Sparrow (Zonotrichia capensis, Statius Müller, 1776) at different elevations in the Tropical Andes. Elevation strongly influences the evolution of life history traits associated with bird physiology and reproduction. Since life history traits in birds are modulated by environmental factors that vary with elevation, we expected to find changes in breeding biology traits of Z. capensis at different elevations. In this study, we compared the breeding biology (clutch size, egg volume, and reproductive activity) of a non-migratory population of Z. capensis in two localities at different elevations (low and high elevations, 1 800 m a.s.l., and 3 800 m a.s.l., respectively) and same latitude in the Colombian Tropical Andes for a one-year period. We found no differences in clutch size between the localities; however, egg volume was higher at high elevation. Furthermore, the reproductive activity differed significantly between localities. We propose that clutch size is likely conserved throughout the altitudinal distribution of Z. capensis since the species evolved in Tropical lowlands. On the other hand, the larger egg volume at high elevation could obey local environmental factors that may favor the reproductive success of the population.

Resumen: Biología reproductiva en una población de Gorrión Copetón (Zonotrichia capensis, Statius Müller, 1776) a diferente elevación en los Andes tropicales. La elevación influye fuertemente en la evolución de los rasgos de historia de vida asociados con la fisiología y reproducción de las aves. Dado que los rasgos de historia de vida en las aves están modulados por factores ambientales que varían con la elevación, esperábamos encontrar cambios en los rasgos de la biología reproductiva de Z. capensis a diferentes elevaciones. En este estudio, comparamos la biología reproductiva (tamaño de puesta, volumen del huevo y actividad reproductiva) de una población no migratoria de Z. capensis en dos localidades a diferente elevación (elevación baja 1 800 m snm, y elevación alta 3 800 m snm,) y a la misma latitud en los Andes tropicales colombianos por un período de un año. No encontramos diferencias en el tamaño de puesta entre las localidades; sin embargo, el volumen del huevo fue mayor en elevación alta. Además, la actividad reproductiva difirió entre las localidades. Proponemos que el tamaño de puesta probablemente se conserve en toda la distribución altitudinal de Z. capensis, ya que la especie evolucionó en las tierras bajas tropicales. Por otro lado, el mayor volumen del huevo a elevación alta podría obedecer a factores ambientales locales que pueden favorecer el éxito reproductivo de la población.

Ethnic Difference of Thrombogenicity in Patients with Cardiovascular Disease: a Pandora Box to Explain Prognostic Differences

Arterial and venous atherothrombotic events are finely regulated processes involving a complex interplay between vulnerable blood, vulnerable vessel, and blood stasis. Vulnerable blood (‘thrombogenicity’) comprises complex interactions between cellular components and plasma factors (inflammatory, procoagulant, anticoagulant, and fibrinolytic factors).The extent of thrombogenicity may determine the progression of atheroma and the clinical manifestation of atherothrombotic events, with the highest thrombogenicity in African Americans and lowest in East Asians. Inherent thrombogenicity may influence clinical efficacy and safety of specific antithrombotic treatments in high-risk patients, which may in part explain the observation that East Asian patients have reduced anti-ischemic benefits and elevated bleeding risk with antithrombotic therapy compared to Caucasian patients. In this review, we discuss available evidence regarding the racial differences inthrombogenicity and its impact on clinical outcomes among patients with atherosclerotic cardiovascular disease.

Ethnic Difference of Thrombogenicity in Patients with Cardiovascular Disease: a Pandora Box to Explain Prognostic Differences

Arterial and venous atherothrombotic events are finely regulated processes involving a complex interplay between vulnerable blood, vulnerable vessel, and blood stasis. Vulnerable blood (‘thrombogenicity’) comprises complex interactions between cellular components and plasma factors (inflammatory, procoagulant, anticoagulant, and fibrinolytic factors).The extent of thrombogenicity may determine the progression of atheroma and the clinical manifestation of atherothrombotic events, with the highest thrombogenicity in African Americans and lowest in East Asians. Inherent thrombogenicity may influence clinical efficacy and safety of specific antithrombotic treatments in high-risk patients, which may in part explain the observation that East Asian patients have reduced anti-ischemic benefits and elevated bleeding risk with antithrombotic therapy compared to Caucasian patients. In this review, we discuss available evidence regarding the racial differences inthrombogenicity and its impact on clinical outcomes among patients with atherosclerotic cardiovascular disease.

Effects of flunixin meglumine, meloxicam, and firocoxib on the acute-phase proteins in horses following standing castration

ABSTRACT: Excessive infection and inflammation are the most common complications associated with castration. The objective of this study was to compare the efficacy of flunixin meglumine (FM), meloxicam (MX), or firocoxib (FX) for inflammation control after castration in horses using acute-phase proteins (APP) as markers of inflammation. Thirty healthy, unbroken, mixed-breed horses (body weight 358.62±45.57kg and age 4.99±2.63 years) were randomly (n=10 animals/group) allocated to receive one of three different post-castration anti-inflammatory medicines: Group 1 (FM 1.1mg/kg bwt, IV, s.i.d for 5 days); Group 2 (MX 0.6mg/kg bwt, IV, s.i.d for 5 days); and Group 3 (FX 0.1mg/kg bwt, IV, s.i.d for 5 days). All horses were castrated in standing position, using the open technique. Serum and peritoneal APP concentrations were measured by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) and determined before castration (0), and 3, 5, 24, 48, 72, 120 and 168 hours after castration. The results were submitted to analysis of variance using the SAS statistical program, and means were compared by the Student-Newman-Keuls test (p 0.05). Three animals from the MX group developed hyperthermia (with rectal temperatures of 39.8, 39.3 and 38.9°C on day 4, 5 and 6, respectively) and showed local clinical signs of inflammation (inguinal and excessive scrotal edema) and reluctance to walk, as well as a rigid gait of the hind limbs. The same complications were observed in one FX horse. No complications were observed among the FM animals. The castration resulted in significant changes in serum and peritoneal values of total proteins, ceruloplasmin (Cp), transferrin (Tf), albumin (Alb), haptoglobin (Hp) and 1-acid glycoprotein (Gp) in animals of all experimental groups. However, the animals of the MX and FX groups presented more intense acute phase response compared to the animals of the FM group. Changes in the APP were associated with the surgical trauma of castration, but the differences between groups were associated with the ability of the nonsteroidal anti-inflammatory drug to control the inflammation. In conclusion, and based on the findings of acute phase proteins, flunixin is more efficient to control the magnitude of inflammation following castration as compared to meloxicam and firocoxib.

RESUMO: Infecção e inflamação excessivas são as complicações mais comuns associadas à castração. O objetivo deste estudo foi comparar a eficácia do flunixin meglumine (FM), meloxicam (MX) ou firocoxib (FX) no controle da inflamação após a castração em cavalos usando proteínas da fase aguda (APP) como marcadores de inflamação. Trinta equinos saudáveis (358,62±45,57kg; 4,99±2,63 anos) foram em função dos anti-inflamatórios utilizados após as castrações aleatoriamente (n= 10 animais/grupo) alocados em três diferentes grupos: Grupo 1 (FM 1,1mg/kg de peso, IV, sid por 5 dias); Grupo 2 (MX 0,6mg/kg de peso, IV, s.i.d por 5 dias); e Grupo 3 (FX 0,1mg/kg de peso, IV, s.i.d por 5 dias). Todos os cavalos foram castrados em posição quadrupedal, utilizando a técnica aberta. As concentrações de APP sérica e peritoneal foram separadas por eletroforese em gel de poliacrilamida (PAGE) com dodecil-sulfato de sódio (SDS) e determinadas no momento 0 (antes da castração) e com 3, 5, 24, 48, 72, 120 e 168 horas após a castração. Os resultados foram submetidos à análise de variância pelo programa estatístico SAS e as médias foram comparadas pelo teste de Student-Newman-Keuls (p 0,05). Três animais do grupo MX desenvolveram hipertermia (com temperatura retal de 39,8, 39,3 e 38,9° C nos dias 4, 5 e 6, respectivamente) e mostraram sinais clínicos locais de inflamação (edema inguinal e escrotal excessivo) e relutância em andar, bem como marcha rígida dos membros posteriores. As mesmas complicações foram observadas em um cavalo do FX. Não foram observadas complicações entre os animais do FM. Independente do grupo, a castração resultou em alterações significativas nos valores séricos e peritoneais de proteínas totais, ceruloplasmina (Cp), transferrina (Tf), albumina (Alb), haptoglobina (Hp) e glicoproteína ácida 1 (Gp). No entanto, os animais dos grupos MX e FX apresentaram resposta de fase aguda mais intensa quando comparados aos animais do FM. Alterações na resposta de fase aguda deveram-se ao trauma cirúrgico da castração, mas as diferenças entre os grupos foram associadas à capacidade do anti-inflamatório em controlar a inflamação. Em conclusão, baseado da resposta de fase aguda, o flunixin em comparação com o meloxicam e o firocoxib é mais eficiente no controle da inflamação após a castração em equinos.

Introducción. La calidad de vida relacionada con la salud (CVRS) es una medida de resultado de salud. Evalúa el impacto subjetivo y global de las enfermedades en la vida cotidiana. Brinda información multidimensional sobre el bienestar físico, relación familiar y sus pares. Los estudios de CVRS de hermanos son limitados.Objetivo. Comparar CVRS de los hermanos de pacientes pediátricos con patologías reumáticas crónicas, trasplante renal o hepático con la de niños sanos con hermanos sin enfermedades crónicas.Resultados. Se compararon hermanos de niños con trasplante renal (n: 65), trasplante hepático (n: 35) y patologías reumáticas crónicas (n: 36) con el grupo control de niños sanos (n: 51). El grupo total de hermanos tuvieron puntuación más baja, estadísticamente significativa, en las dimensiones bienestar físico, amigos-apoyo social y recursos económicos. Los hermanos de trasplante renal tuvieron baja puntuación en las dimensiones de bienestar físico (p < 0,02; tamaño del efecto ­TE­: 0,66) y recursos económicos (p < 0,01; TE: 0,66). Los hermanos de trasplante hepático percibieron menor bienestar físico (p = 0,04), tenían menos amigos y apoyo social (p < 0,01), dificultades en el entorno escolar (p < 0,02) y recursos económicos (p < 0,01). Los hermanos de patologías reumáticas crónicas tuvieron menor bienestar físico (p < 0,05; TE: 0,44) y apoyo social-amigos (p < 0,01; TE: 0,58).Conclusión. La CVRS de niños/as sanos de hermanos con patologías crónicas es menor en bienestar físico, amigos-apoyo social y recursos económicos comparada con el grupo de niños sanos.

Introduction. Health-related quality of life (HRQoL) is a measure of health outcomes. It assesses the subjective and overall impact of diseases on daily life. It also provides multidimensional data about physical well-being, family and peers relations. HRQoL studies on siblings are limited.Objective. To compare HRQoL among siblings of pediatric patients with chronic rheumatic diseases, kidney or liver transplant and healthy children whose siblings had no chronic conditions.Results. The siblings of children with kidney transplant (n: 65), liver transplant (n: 35), and chronic rheumatic diseases (n: 36) were compared to the healthy children group (n: 51). The total siblings group had a lower, statistically significant score in the physical well-being, social support and peers, and financial resources dimensions. The siblings of kidney transplant patients had a low score in the physical well-being (p < 0.02; effect size [ES]: 0.66) and financial resources (p < 0.01; ES: 0.66) dimensions. The siblings of liver transplant patients perceived a lower physical well-being (p = 0.04), less social support and peers(p < 0.01), and difficulties in relation to school environment (p < 0.02) and financial resources (p < 0.01). The siblings of those with chronic rheumatic diseases had a lower score in the physical well-being (p < 0.05; ES: 0.44) and social support and peers (p < 0.01; ES: 0.58) dimensions.Conclusion. HRQoL among healthy children whose siblings have a chronic disease was lower in the physical well-being, social support and peers, and financial resources dimensions compared to the healthy children group.
