RESUMO

Tumours in patients with head and neck cancer (HNC) are associated with a more significant decrease in quality of life compared with the rest of patients with cancer. We present a patient with pain due to HNC successfully treated with bipolar radiofrequency ablation. A man in his 70s presented with a tumour in the left V2 and V3 region, with disabling pain, Visual Analogue Scale (VAS) score of 10/10, pain on swallowing, chewing and speaking, 3 months of evolution. The patient was evaluated in the pain management department, and the interventional treatment proposed consisted of bipolar pulsed radiofrequency, followed by bipolar thermal radiofrequency of the left V2 and V3 branches with fluoroscopic guidance to achieve better control and coverage of the affected trigeminal branches. Immediately after the procedure, the patient reported a significant improvement in pain with a 0-10 VAS; hypoesthesia in the affected V2 and V3 territory was identified, but no motor weakness. The improvement in pain was maintained for 6 months with a significant improvement in quality of life and pain, which allowed him to speak, chew and swallow without pain. Later, the patient died from complications associated with the disease. The treatment approach in these patients is both pain treatment and achieving independence by allowing better speech ability and improving eating, the above as a pillar of treatment focused on improving the patient's quality of life. This approach is a potential tool in the early stage of the disease in patients with pain due to HNC.

RESUMO

BACKGROUND: Sacral metastases represent the lowest percentage of invasion to the spine, however, as chemotherapy treatments progress, the cancer survival rate has become higher, and the percentage of sacral metastases has increased. Treatment options for sacrum metastases are surgery, radiotherapy, and minimally invasive techniques such as sacroplasty and radiofrequency ablation. Knowing the repercussions that advancing the needle anteriorly (viscera) or medially (sacral roots) can have during the sacroplasty we are describing a technique to perform c-arm sacroplasty in coaxial vision, to identify the anterior sacral cortical bone that is in the limits of the pelvic viscera as well as the sacral foraminal line. CASE PRESENTATION: In the current report, we present a 75-year-old male patient with prostate cancer metastatic to S1, S2, S3 and iliac, with severe lumbar axial pain VAS 8/10. With a caudal tilt between 35-45 degrees until aligning the sacrum in a coaxial view, a 11-gauge Jamshidi needle is advanced from s3 to s1. The trajectory of the needle during the procedure is corroborated in AP and lateral, S1 is cemented, and the needle is withdrawn to cement S2 and S3. After the sacroplasty with the coaxial access, the patient reported VAS 1-2/10. CONCLUSIONS: It is important to offer an adequate quality of life to patients with sacral fractures, whether associated with cancer or sacral insufficiency fractures (SIF). Sacroplasty, being a recently described technique, can be a very viable option for these patients, that's why it is important to have safe and reliable techniques to complement the approach of this minimally invasive technique.The coaxial access may be a safe and practical way to perform sacroplasty in these patients.

RESUMO

Resumen Las condiciones laborales hacen referencía a las particularidades del entorno o ambiente en el que se realizan las actividades de trabajo. A lo largo de la história, las condiciones laborales de los docentes han experimentado contínuas transformaciones bajo distintas reformas educativas, que repercuten en su grado de bienestar en el trabajo. El objetivo de la presente investigación es analizar la relación entre la valoración de las condiciones de trabajo y el bienestar laboral percibido en 132 docentes de primaria y secundaria de colegios públicos y privados de la ciudad de Cali, Colombia. Para tal efecto se utilizó una metodología cuantitativa con diseño correlacional y muestreo no probabilístico intencional. Se evidenció un aumento en el tiempo dedicado a realizar la función docente, la organización y la carga laboral, lo cual genera en los docentes afectaciones en su bienestar laboral. Se encontró una relación significativa entre las condiciones de trabajo y el bienestar laboral de los docentes, de manera que el tipo de contratación temporal genera en ellos inseguridad, inestabilidad y algunos efectos colaterales como somatizaciones y agotamiento, perjudicando su rendimiento laboral, salud y bienestar.


Abstract Working conditions refer to the particularities of the environment in which work activities are carried out. Throughout history, teachers' working conditions have undergone continuous transformations under different educational reforms, which have an impact on their well-being at work. The research objective was to analyze the relationship between the assessment of working conditions and perceived occupational well-being in 132 primary and secondary teachers from public and private schools in the city of Cali, Colombia. It was carried out by means of a quantitative methodology with a correlational design and intentional non-probabilistic sampling. It was evidenced that increasing in the time devoted to performing the teaching function, organization and workload affects teachers´ welfare. Additionally, a significant relationship was found between the working conditions and the labor well-being of teachers. The type of short-term contracting generates job insecurity and instability and some collateral effects such as somatization and exhaustion, which are detrimental to their work performance, health, and wellbeing.

RESUMO

Resumen Introducción: La cardiopatía isquémica es un problema de salud pública y puede tratarse por medio de la revascularización miocárdica. Objetivo: Estructurar el primer perfil epidemiológico y clínico de los pacientes intervenidos en Tolima. Materiales y método: Es un estudio de corte transversal, de 183 pacientes mayores de 18 años programados para revascularización miocárdica entre septiembre de 2018 y septiembre de 2019. Se eligieron variables clínicas y demográficas. Se realizó un análisis descriptivo, un análisis bivariado para mortalidad y circulación extracorpórea, y una regresión logística para la mortalidad intrahospitalaria. Resultados: La edad media de los pacientes fue de 66.7 años y un 68.85% correspondió a la población femenina. Se presentó HA en 80.33%, tabaquismo en 49.18%, dislipidemia en 44.81% y DM en 40.98%. Se registró mayor proporción de complicaciones en los pacientes intervenidos sin CEC, como complicaciones pulmonares, FA de novo y una estancia intrahospitalaria y posoperatoria mayor. Los pacientes que fallecieron tuvieron mayor proporción de complicaciones, mayor estancia hospitalaria, mayor cantidad de reintervenciones y tiempo de ventilación mecánica. El modelo de regresión reveló una relación con mortalidad para los pacientes que tuvieron requerimiento de diálisis (OR = 8.7) complicaciones pulmonares (OR = 10.5) y desarrollo de FA de novo (OR = 11.3). Conclusiones: Este estudio caracteriza a la población para generar marcos de referencia en un grupo poco estudiado como el tolimense. De modo adicional, se presentaron mejores desenlaces en los pacientes llevados a revascularización miocárdica con circulación extracorpórea, y unas relaciones claras de mortalidad y complicaciones posoperatorias.


Abstract Introduction: The ischemic cardiopathy is a public health issue, that can be treated with a coronary artery bypass grafting (CABG). Objective: To present the first clinical and epidemiological profile of CABG treated patients in Tolima, Colombia. Materials and method: We conduct a cross sectional study, including 183 patients driven to a CABG procedure, between September 2018-2019. We chose clinical and demographic variables. And posteriorly, performed a descriptive and bivariate analysis, including mortality and extracorporeal circulation. Besides, we completed a logistic regression for intrahospital mortality. Results: The average age of our patients was 66,7 years, and 68.85% were female. They presented in an 80.33% arterial hypertension, smoked an 49.18%, had dyslipidemia and diabetes 44.81% and 40.95% respectively. There were more complications in patients who were drove into on pump CABG, primarily pulmonary complications, atrial fibrillation, mayor intrahospital and post-operatory stay. The patients who died, present more complications, intrahospital stay, reinterventions and mechanic ventilation time. Our regression model evidenced mortality association with post-operatory dialysis (OR = 8.7), pulmonary complications (OR = 10.5) and new atrial fibrillation (OR = 11.3). Conclusions: This study aim to characterize the Tolima's population, creating a reference in this less studied population. On the other side, the study discuss the better outcomes in patients taken to myocardial bypass with extracorporeal membrane oxygenation. And the association between dead and certain postoperative complications.

RESUMO

Background: Detecting cancer at early stages significantly increases patient survival rates. Because lethal solid tumors often produce few symptoms before progressing to advanced, metastatic disease, diagnosis frequently occurs when surgical resection is no longer curative. One promising approach to detect early-stage, curable cancers uses biomarkers present in circulating extracellular vesicles (EVs). To explore the feasibility of this approach, we developed an EV-based blood biomarker classifier from EV protein profiles to detect stages I and II pancreatic, ovarian, and bladder cancer. Methods: Utilizing an alternating current electrokinetics (ACE) platform to purify EVs from plasma, we use multi-marker EV-protein measurements to develop a machine learning algorithm that can discriminate cancer cases from controls. The ACE isolation method requires small sample volumes, and the streamlined process permits integration into high-throughput workflows. Results: In this case-control pilot study, comparison of 139 pathologically confirmed stage I and II cancer cases representing pancreatic, ovarian, or bladder patients against 184 control subjects yields an area under the curve (AUC) of 0.95 (95% CI: 0.92 to 0.97), with sensitivity of 71.2% (95% CI: 63.2 to 78.1) at 99.5% (97.0 to 99.9) specificity. Sensitivity is similar at both early stages [stage I: 70.5% (60.2 to 79.0) and stage II: 72.5% (59.1 to 82.9)]. Detection of stage I cancer reaches 95.5% in pancreatic, 74.4% in ovarian (73.1% in Stage IA) and 43.8% in bladder cancer. Conclusions: This work demonstrates that an EV-based, multi-cancer test has potential clinical value for early cancer detection and warrants future expanded studies involving prospective cohorts with multi-year follow-up.

RESUMO

The preservation of body proteins is essential to guarantee their functions in organisms. Therefore, the utilization of amino acids as energy substrates is regulated by a precise fine-tuned mechanism. Recent evidence suggests that the transcription factors peroxisome proliferator-activated receptor alpha (PPARα) and hepatocyte nuclear factor 4 alpha (HNF4α) are involved in this regulatory mechanism. Thus, the aim of this study was to determine how these transcription factors interact to regulate the expression of amino acid catabolism genes. In vivo studies using PPARα-knockout mice (Pparα-null) fed different amounts of dietary protein showed that in the absence of PPARα, there was a significant increase in HNF4α abundance in the liver, which corresponded with an increase in amino acid catabolizing enzyme (AACE) expression and the generation of increased amounts of postprandial urea. Moreover, this effect was proportional to the increase in dietary protein consumed. Chromatin immunoprecipitation assays showed that HNF4α can bind to the promoter of AACE serine dehydratase (SDS), an effect that was potentiated by dietary protein in the Pparα-null mice. The mechanistic studies revealed that the presence of retinoid X receptor alpha (RXRα) is essential to repress HNF4α activity in the presence of PPARα, and this interaction accelerates HNF4α degradation via the proteasome pathway. These results showed that PPARα can downregulate liver amino acid catabolism in the presence of RXRα by inhibiting HNF4α activity.

RESUMO

Introducción La transfusión posoperatoria es una complicación frecuente de la artroplastia de rodilla. El ácido tranexámico (AT) ha demostrado eficacia en disminuir la probabilidad de sangrado, sin embargo, son pocos los estudios en cuanto al tema. Los objetivos del estudio son: 1) Comparar el efecto de dosis única de 1g de ácido tranexámico preoperatoria en la tasa de transfusión en pacientes a quienes se realizó artroplastia de rodilla entre enero de 2010 y diciembre de 2016. 2) Caracterizar población de pacientes a quienes se realizó artroplastia de rodilla. 3) Determinar tasa de transfusión sanguínea en grupos de estudio. 4) Determinar factores de riesgo para transfusión sanguínea en pacientes con artroplastia de rodilla. Materiales y Metodos Estudio observacional descriptivo de tipo corte transversal analítico retrospectivo. Resultados Tasa de transfusión en grupo sin AT=15,2%; en grupo con AT=1,2%. La sangre perdida y el tiempo quirúrgico no presentaron diferencias estadísticamente significativas entre los grupos (p>0,05). Se consideran factores de riesgo: anticoagulación (OR 3,52; IC95% 1,28-9,65), insuficiencia renal crónica (OR 5,91; IC95% 1,11-31,27) y artritis reumatoidea (OR 55,83; IC95% 18,34-169,91). Discusión Según regresión logística, la cantidad de sangre perdida y administración del AT pueden predecir con un 97.5% de acierto la probabilidad de transfusión ante presencia de artritis reumatoide. La pérdida sanguínea mayor a 400 cc aumenta significativamente la probabilidad de transfusión cuando no se administra AT. El uso de AT preoperatorio es efectivo en reducir la tasa de transfusión sanguínea en pacientes a quienes se realiza ATR. Nivel de Evidencia: III


Background Postoperative transfusion is a common complication of knee arthroplasty. Tranexamic acid has shown efficacy in reducing the probability of bleeding, however, there are few studies on the subject. The aims of the study are: 1) To compare the effect of a single dose of 1g of preoperative tranexamic acid on the transfusion rate in patients who underwent knee arthroplasty between January 2010 and December 2016. 2) Characterize the population of patients who underwent knee arthroplasty. 3) Determine blood transfusion rate in study groups. 4) Determine risk factors for blood transfusion in patients with knee arthroplasty. Methods A descriptive observational study of a retrospective analytical cross section type was performed. Results Group transfusion rate without TA=15.2%, group transfusion rate with TA=1.2%. The blood loss and the surgical time did not show statistically significant differences between the groups (p>0.05). The following are considered risk factors: anticoagulation (OR: 3.52; 95%CI 1.28-9.65), chronic renal failure (OR: 5.91; 95%CI 1.11-31.27) and rheumatoid arthritis (OR: 55.83; 95%CI 18.34-169.91). Discussion According to logistic regression, the amount of blood lost and administration of the TA can predict with a 97.5% accuracy the probability of transfusion in the presence of rheumatoid arthritis. Blood loss greater than 400 cc significantly increases the probability of transfusion when TA is not administered. The use of preoperative TA is effective in reducing the rate of blood transfusion in patients who undergo ATR Evidence Level: III

RESUMO

Background: INR is used to monitor the treatment with vitamin K antagonists. A strategy to reduce waiting times for sampling is to measure INR in a capillary sample using a portable point of care (POC) type coagulometer. Aim: To evaluate the correlation of CoaguChek Pro II™, Xprecia™ and microINR™ with venous INR measured at the clinical laboratory and their ease of use. Materials and Methods: Patients provided capillary and venous blood samples for parallel tests comparing Xprecia™ Stride with CoaguChek Pro II™ and with venous INR, microINR™ with CoaguChek Pro IITM and with venous INR. The devices' ease of use was assessed surveying the sampling staff. Results: The three tested devices had good correlation coefficients with venous INR: CoaguChek Pro IITM 0.953 and 0.962; Xprecia™ of 0.912 and microINR™ of 0.932. The correlation coefficient of Xprecia™ with CoaguChek Pro IITM was 0.937 and microINR™ with CoaguChek Pro IITM was 0.976. Conclusions: CoaguChek Pro IITM, Xprecia™ and microINR™ results had a good correlation coefficient with INR measured at the laboratory. Our results indicate that, in the hands of trained users, POC-type coagulometers are reliable and acceptable for routine use in anticoagulant treatment control.

RESUMO

The increased use of CT scans has raised concerns regarding the risks of early radiation exposure in the Puerto Rico pediatric population. Available literature sustains that repeated exposure to imaging-related radiation in the pediatric population is associated with a 3-fold increase in the risk of developing pediatric hematogenous and central nervous system malignancies. It is for this reason that an international effort known as the Image Gently Campaign was created, mostly based on the "As Low As Reasonably Achievable" (ALARA) principle described by the Center for Disease Control. With this in mind, our aim was to identify whether there are any discrepancies in imaging tendencies outside our pediatric academic center in Puerto Rico and to determine whether our patients are at increased risk of over-radiation. There were 181 patients; five were excluded because of incomplete data. Our results show that children with appendicitis who are evaluated at nontertiary centers are more likely to have a CT scan performed (93%, OR: 4.054; 95% confidence interval: 2.6-6.4), as opposed to a nonradiating imaging study. In the Pediatric University Hospital, a CT scan was performed as the initial study in 23 per cent of the patients (OR: 0.09; 95% confidence interval: 0.05-0.18), favoring ultrasound as the diagnostic modality of choice. Our concern is that if this trend does not change, our pediatric population might have an increased risk of developing associated malignancies. We believe a local effort toward educational strategies should be implemented to prevent radiation overexposure in our pediatric patients.

RESUMO

Resumen El objetivo general de la presente investigación fue identificar los factores psicosociales in-tralaborales y extralaborales en los trabajadores de una institución del sector salud que presta servicios de alta complejidad (nivel III) de la ciudad de Cali, Colombia. La investigación fue de tipo descriptivo, con un diseño transversal. Se aplicaron la forma A y B del Cuestionario de Factores de Riesgo Psicosocial Intralaboral y el Cuestionario de Factores de Riesgo Psicosocial Extralaboral (Ministerio de Protección Social & Pontificia Universidad Javeriana Bogotá, 2010) a una muestra de 183 trabajadores. Los resultados de la investigación indican que los dominios donde se presenta mayor riesgo psicosocial son demandas del trabajo y control sobre el trabajo. A nivel extralaboral, las condiciones que presentan mayor riesgo son: tiempo fuera del trabajo, situación económica del grupo familiar, características de la vivienda y de su entorno, y desplazamiento vivienda-trabajo. Se concluye a nivel general que la clínica se encuentra en un nivel de riesgo psicosocial alto, por lo cual se requiere la implementación de un Programa de Vigilancia Epidemiológica en Riesgo Psicosocial para prevenir respuestas de estrés y enfermedades asociadas.


Abstract The purpose of this research study was to identify the psychosocial in-workplace and out-of-workplace risk factors in the workers of a health sector institution that provides high complexity services (level III) in the city of Cali, Colombia. This was a study with a descriptive cross-sectional research design. Form A and B of the Questionnaire of Psychosocial Risk Factors In-workplace and the Questionnaire of Factors of Psychosocial and Out-of-workplace Risk (Ministry of Social Protection & Pontificia Universidad Javeriana Bogotá, 2010) were applied to a sample of 183 workers. The results show that the domains where psychosocial risk is most prevalent are labor demands and control over work. At the out-of-workplace level, the conditions that represent the greatest risk are: time away from work, financial situation of the family group, characteristics of the home and its environment, and commuting. We concluded that the clinic is at a high level of psychosocial risk, for which the implementation of an Epidemiological Surveillance Program for Psychosocial Risk is required to prevent stress responses and associated diseases.

Objetivo: Identificar el nivel de estrés laboral en personal con cargos asistenciales de cuatro instituciones de salud nivel III de la ciudad de Cali-Colombia. Materiales y métodos: El estudio fue de tipo descriptivo, con diseño transversal. Se aplicó el cuestionario para la evaluación del estrés tercera versión del Ministerio de la Protección Social a una muestra de 595 participantes, con cargo asistencial que implica la atención sanitaria al paciente, en procedimientos de alta complejidad como cirugía, hospitalización, urgencias, cuidados intensivos. Resultados: El personal con cargo asistencial de las cuatro instituciones de salud nivel III presenta nivel alto de estrés laboral, concretamente en los síntomas fisiológicos, e intelectuales y laborales. Conclusiones: La prevalencia de estrés laboral en el personal asistencial puede asociarse con las características de rol, las condiciones laborales y la exposición permanente a enfermedades contagiosas propias del contexto de las instituciones de salud.


Abstract Introduction: Stress is understood as the set of physiological, behavioral, emotional and cognitive responses, which result in the process of adaptation to the demands derived from the working conditions, before which people evaluate that their coping resources are insufficient. Objective: To identify the level of occupational stress in staff with care positions of four level III health institutions in the city of Cali, Colombia. Materials and methods: A descriptive study with transversal design was made. The third version stress assessment questionnaire was applied Ministry of Social Protection. The sample was 595 participants with care charge, which involves the patient's health care in procedures of high complexity such as surgery, hospitalization, emergencies, intensive care. Results: The staff with healthcare charge of the four level III health institutions presents high level of occupational stress, particularly in the physiological, intellectual and labor symptoms. Conclusions: The prevalence of occupational stress in health care personnel can be associated with the characteristics of role, working conditions and the permanent exposure to communicable diseases inherent in the context of healthcare institutions.

RESUMO

Introducción: El acceso intraóseo es considerado actualmente como una alternativa rápida y eficaz en situaciones en las cuales no es posible lograr un acceso intravenoso en un tiempo preestablecido, principalmente en pacientes que presenten shock grave o paro cardiorrespiratorio, siendo de vital importancia los conocimientos relacionados con su colocación, desde los reparos anatómicos hasta los dispositivos utilizados para su realización. Objetivos: Determinar los conocimientos que poseen los profesionales de la salud acerca del acceso intraóseo. Material y Metodo: Estudio descriptivo y transversal. Encuestas al personal de la salud que concurre a la institución. Resultados: Se realizaron 222 encuestas a enfermeros (37), estudiantes de enfermería (86), médicos (46) y estudiantes de medicina (53). El rango etario fue de 21-59 años. 27, 03% (60) conoce la vía intraósea como acceso vascular; 25, 22% (56) han recibido algún tipo de formación acerca de la colocación de accesos intraóseos, siendo la misma cantidad de profesionales los que pudieron enumerar los sitios anatómicos correspondientes. Sólo un 13, 06% pudieron indicar precisamente los reparos anatómicos necesarios para su colocación y, por último, únicamente 23, 42% de los encuestados conocía si su lugar de desempeño disponía de sets para la colocación de dicha vía. Conclusión: Son muy pocos los profesionales de la salud que tienen conocimientos acerca de la colocación del acceso vascular intraóseo, siendo escasamente promovidos durante su formación. Es de suma importancia promover programas de instrucción para la utilización de dicho acceso, ya que es bien sabido la gran utilidad que presenta el mismo, más aún en casos de riesgo de vida en el que no es posible contar con otro acceso vascular.


Introduction: Intraosseous access is currently considered a quick and effective alternative in situations in which it is not possible to achieve intravenous access in a pre-established time, mainly in patients presenting with severe shock or cardiorespiratory arrest, being of vital importance the knowledge related to its placement, from the anatomical repairs to the devices used for its realization. Objectives: To determine the knowledge held by health professionals about intraosseous access. Material and Method: Descriptive and transversal study. Surveys to health personnel who attend the institution. Results: 222 surveys were carried out to nurses (37), nursing students (86), doctors (46) and medical students (53). The age range was 21-59 years. 27, 03% (60) know the intraosseous route as vascular access; 25, 22% (56) have received some type of training about the placement of intraosseous accesses, with the same number of professionals being able to list the corresponding anatomical sites. Only 13, 06% could precisely indicate the anatomical repairs necessary for their placement and, finally, only 23, 42% of the respondents knew if their place of performance had sets for the placement of said route. Conclusion: Very few health professionals have knowledge about the placement of intraosseous vascular access, being poorly promoted during their training. It is very important to promote instructional programs for the use of such access, since it is well known that it is very useful, especially in cases of life risk in which it is not possible to have another vascular access.

En cuanto a los métodos imageneológicos complementarios, usados criteriosamente ante duda diagnostica pueden ser de utilidad


Introduction: Acute appendicitis is one of the most frequent causes of acute surgical abdomen in our environment, and its diagnosis is mainly clinical. However , the rate of negative or blank appendectomies remain constant. For this reason, the knowledge of the clinic, the use of diagnostic scales and of complementary studies contribute to a more accurate diagnosis. Objective: Clinical correlation with intraoperative and anatomopathological findings. Evaluate the utility of diagnostic scales to reduce negative cases. Material and Methods: Patients admitted to the General Surgery Service of the Central Aeronautical Hospital with right iliac fossa syndrome (FID) diagnosis were checked by guard in the period between January 2017 and January 2018. Alvarado and RIPASA diagnostic scales were used. The use of complementary imaging studies was evaluated. It was discriminated according to sex and age. It was compared with the Anatomo Pathological results. Design: Prospective. Observational Comparative. Results: Data from 118 patients admitted by guard were annalized. Male: 61.86%. Male average age: 24 years old (R: 19-44). Female: 28 years old (R: 18 -68). Frequency of presentation of signs and symptoms: Pain: 100%. Migratory pain: 95.76%. Anorexia: 91.52%. Nausea: 85.58%. Vomiting: 74.57%. Fever: 59.32%. Leukocytosis: 81.35%. Alvarado scale: Sensitivity: 87.28%. Specificity: 66.01%. RIPASA scale: Sensitivity: 94.78%. Specificity: 73.3%. Complementary methods: Radiography: 100%, Abdominal ultrasound: 93.22%, Pathological: 82.20%. TAC: 11.86%, Pathological: 85.71%. Average hospitalization: 3 days. Location of cecal appendix: Internal descending: 55.08%, Retrocecal: 34.74%, other: 10.16%. Pathological Anatomy: Phlegmonous: 41.52%, Congestive: 31.35%, Gangrenous: 16.10%, Perforated: 4.23%, Normal: 4.23%.Conclusion: RIPASA turned out to be the best performance method when results were compared with those of pathological anatomy. That is why the clinical and diagnostic scores we consider are fundamental to approach a diagnosis of certainty and decrease the rate of negative appendectomies. As for the complementary imaging methods, used judiciously before diagnostic doubt can be useful

RESUMO

Introducción: Los accesos venosos han sido empleados desde hace varias décadas. La utilización de estas vías para la administración de fluidos, fármacos, nutrición parenteral o determinación de constantes fisiológicas; ha dependido tanto del conocimiento anatómico como de la disponibilidad de material adecuado. Repasaremos los hitos más importantes de la historia de la cateterización venosa que hicieron posible la base para la colocación de accesos venosos centrales en la actualidad.Metodologia: Se realizo una búsqueda bibliográfica entre Enero y Abril de 2018 utilizando escritura científica con lectura critica a base de fuentes de información como libros de texto y búsquedas avanzadas con filtros selectivos en Pubmed. Desarrollo: Antes del conocimiento y la utilización de equipos de punción percutáneo había que proceder a la exposición quirúrgica del vaso para introducir un catéter venoso. La descripción de la Técnica de Seldinger represento una importante ventaja respecto a la venodisección y el advenimiento de la ultrasonografia (US) facilito su inserción y disminuyo las complicaciones. Conclusión:El cateterismo venoso central es un procedimiento frecuente efectuado por primera vez a principios del siglo XX; convirtiéndose en un pilar de la medicina moderna.


Introduction: Venous access has been used since several decades ago. The use of these venous lines in order to dispense fluids, drugs, parenteral nutrition or monitoring physiological parameters has depended on the anatomical knowledge, as well as on the availability of the appropriate material. We will go through the most important facts along the history of the venous catheterization that created the basis of the actual procedure of central venous access.Methods: A bibliographic search has been made, taking into account the period from January to April 2018, using scientific literature and applying critical reading. The sources of information included textbooks and advanced search applying selective filtering in Pubmed.Development: Before the expertise and the use of equipment for the percutaneous puncture it was necessary to perform a surgical exposure of the vessel in order to introduce a venous catheter. The Seldinger Technique represented a major advantage over venousection, and the advent of ultrasonography improved the placement and decreased complications.Results: The central venous catheterization is a frequent procedure, introduced for the first time in the early twentieth century and it became a fundamental pillar in modern medicine.

RESUMO

Introducción: La atención inicial de los pacientes traumatizados es una de las prácticas médicas más frecuentes en los servicios de urgencias. La adquisición de las habilidades necesarias para el manejo correcto de estos pacientes debe incorporarse desde la formación médica básica. La docencia es una tarea compleja y es necesario implementar múltiples estrategias que garanticen la adquisición de conocimiento, permitiéndole convertirse en una herramienta pedagógica para los médicos en formación y crear nuevas oportunidades para la incorporación de nuevas habilidades para los estudiantes de la escuela de medicina. La correcta identificación de las estructuras anatómicas y la atención inicial del paciente traumatizado permitirán disminuir los posibles eventos adversos y la morbimortalidad de los pacientes quirúrgicos. Objetivos: Demostrar el uso de la enseñanza en la atención inicial del trauma como una herramienta pedagógica para el correcto aprendizaje y entrenamiento del residente de cirugía general. Material y Método: Dos períodos de análisis (enero -diciembre de 2016). En el primer período: sesiones de entrenamiento para residentes de cirugía general en atención inicial en pacientes politraumatizados, aprendizaje de anatomía humana normal en cadáveres formolizados al 10% y el desarrollo de habilidades mediante la aplicación de simuladores básicos y avanzados. En el segundo período: talleres de habilidades iniciales y quirúrgicas destinadas a estudiantes de medicina; dictado por el residente bajo la supervisión de especialistas, evaluando a través de la observación directa y la supervisión de la adquisición de conocimiento. Aprendizaje de los contenidos establecidos y mediante la simulación cognitiva a través del desarrollo de casos clínicos, la retroalimentación y la evolución del médico en entrenamiento. Resultados: 10 residentes de cirugía general. Se evidenció un mejor desempeño de residentes al finalizar el primer periodo evaluando conocimientos teóricos sobre atención inicial de paciente politraumatizado (AIP), identificación de estructuras anatómicas (IEA) y procedimientos y técnicas quirúrgicas (PYTQ). En simulación y habilidades un 70% pudo realizar los ejercicios sin necesidad de participación de instructores. En el segundo periodo se evaluó a estudiantes de grado de la carrera de medicina, los cuales previa instrucción obtuvieron por encima del 60% de conocimientos y habilidades técnicas adquiridas. En este periodo también se pudo evaluar a los residentes en su rol de docentes, los cuales tuvieron un porcentaje promedio de 70% de respuestas positivas sobre el desempeño de estos por parte de los alumnos. Conclusión: El desarrollo de nuevos espacios de aprendizaje favorece la formación continua en trauma de residente. La estrategia pedagógica correctamente planificada y con la supervisión adecuada puede considerarse como una alternativa en los programas de capacitación, y es posible incorporar conocimientos y habilidades en los estudiantes de la carrera de medicina mejorando la calidad educativa de las instituciones


Introduction: The initial care of traumatized patients is one of the most frequent medical practices in the emergency services. The acquisition of the necessary skills for the correct management of these patients should be incorporated from the basic medical training. Teaching is a complex task and it is necessary to implement multiple strategies that guarantee the acquisition of knowledge, allowing it to become a pedagogical tool for doctors in training and create new opportunities for the incorporation of new skills for medical school students. The correct identification of the anatomical structures and the initial care of the traumatized patient will allow to reduce the possible adverse events and the morbidity and mortality of the surgical patients. Objectives: To demonstrate the use of teaching in the initial care of trauma as a pedagogical tool for the correct learning and training of the resident of general surgery. Material and method: : Two periods of analysis (January -December 2016). In the first period: training sessions for residents of general surgery in initial care in polytraumatized patients, learning of normal human anatomy in 10% formolized corpses and the development of skills through the application of basic and advanced simulators. In the second period: workshops of initial and surgical skills aimed at medical students; dictated by the resident under the supervision of specialists, evaluating through the direct observation and supervision of knowledge acquisition. Learning of the established contents by cognitive simulation hrough the development of clinical cases, the feedback and the evolution of the doctor in training. Results: 10 residents of general surgery. A better performance of residents at the end of the first period was evidenced evaluating theoretical knowledge about initial attention of polytraumatized patients (AIP), identification of anatomical structures (IEA) and surgical procedures and techniques (PYTQ). In simulation and skills, 70% could perform the exercises without the need for instructors to participate. In the second period, medical degree students were evaluated, which, after receiving instructions, obtained over 60% of the knowledge and technical skills acquired. In this period it was also possible to evaluate the residents in their role as teachers, who had an average percentage of 70% of positive responses on the performance of these by the students. Conclusions: The development of new learning spaces favors continuous training in resident trauma. The pedagogical strategy correctly planned and with adequate supervision can be considered as an alternative in the training programs, and it is possible to incorporate knowledge and skills in the medical career students improving the educational quality of the institutions

RESUMO

Introducción: El exceso de horas de trabajo, la sobrecarga laboral y la falta de descanso llevan a la fatiga mental y física que afectan consecuentemente al rendimiento y al manejo de los pacientes que son el prefacio de una realidad cada vez más frecuente: el error médico. En los profesionales de la salud, la fatiga constituye un peligro importante desde la perspectiva de los factores humanos porque afecta a la mayoría de los aspectos de la capacidad de la persona, repercutiendo en la seguridad de sus pacientes. Objetivos: Exponer la importancia de establecer las acciones tendientes a reducir los eventos adversos por la sobrecarga horaria. Material y Método: Se analizaron 205 encuestas confidenciales y anónimas realizadas a profesionales médicos pertenecientes al servicio de Emergencias del Hospital de Morón Ostaciana C. de Lavignole y el Hospital Aeronáutico Central, en el período comprendido entre el 1de Mayo de 2016 y el 30 de Septiembre de 2016. La población analizada corresponde a 205 médicos, 95 (46,34%) hombres y 110 (53,66%) mujeres, distribuidos según rango etario. Resultados: De la totalidad de los médicos encuestados, solo el 2,43% realiza guardias de 12 horas semanales. 31,7% realizan guardias de 24 horas semanales. 9,75%, guardias de 36 horas semanales. 31,7% cumplen con 48 horas de guardias semanales y el 24,39%, exceden las 48 horas de guardias semanales. El 73,17%, luego de finalizar su guardia, continúa con actividad de planta o quirúrgica, según sea su especialidad. Esto pone de manifiesto que el 73,16% posee pluriempleo. Conclusión: En los profesionales de la salud, la fatiga constituye un peligro importante desde la perspectiva de los factores humanos porque afecta a la mayoría de los aspectos de la capacidad de la persona, repercutiendo en la seguridad de sus pacientes. Los sistemas deberán rediseñar los aspectos sustantivos en la identificación y notificación de errores; como en la prevención del mismo.


Introduction: Excessive hours of work, work overload and lack of rest lead to mental and physical fatigue, affecting performance and patient ́s management that lead to an increasingly frequent reality: the medical error. In health professionals, fatigue is an important danger from human ́s factors perspective because it affects most of the aspects of the professional ́s capacity, affecting patient ́s security. Objective: Expose the importance of establishing action tending to reduce the adverse events of work overload. Material and method: 205 confidential and anonymous surveys were made to health professionals of the Emergency Service from Hospital de Morón Ostaciana C. de Lavignolle and Hospital Aeronáutico Central, between May 1st, 2016 to September 30th, 2016. Results: 2,43% do 12hs weekly guard. 31,7% do 24hs weekly guard. 9,75% do 36hs weekly guard. 31,7% do 48hs weekly guard and 24,39% exceed 48hs weekly guard. 73, 17% after finishing their guard, continuo with their professional activities, having 73,16% more than one job. Conclusions: Fatigue constitute an important danger in health professionals because it affects most of the aspects of the professional ́s capacity, affecting patient ́s security. Mistakes identification and notification must be redesigned including the prevention of them

RESUMO

Introducción: la capacitación de los jóvenes en los contenidos de la violencia puede mejorar sus relaciones con padres, maestros y amigos. Objetivo: evaluar una intervención educativa en salud acerca de la violencia y sus consecuencias en adolescentes. Métodos: investigación de tipo evaluativa realizada en el 2013 en 23 estudiantes identificados con problemas de violencia y que cursan grados intermedios en una escuela pública en Puerto Rico. El primer segmento de la intervención tuvo énfasis en la parte cognoscitiva y en la segunda parte se utilizó una estrategia motivacional para modificar actitudes hacia la violencia. Antes y después de la intervención se aplicó un cuestionario basado en el Modelo de Conocimiento, Actitudes y Prácticas para la prevención de la violencia. Resultados: El 52,17 por ciento (n= 12) eran féminas. La edad promedio fue de 14 ± 1,51 años. Después de la intervención, el 56,53 por ciento (n= 13) de los participantes demostró tener buen conocimiento sobre violencia y el 47,05 por ciento (n= 8) tenían una actitud positiva hacia la misma. La intervención logró un cambio en conocimiento (U=−2,178, p= 0,03), pero no hubo diferencia significativa en cuanto a la actitud hacia la violencia (U=−1,124, p= 0,26). Conclusiones: la intervención realizada es eficaz en el incremento de conocimientos acerca de la violencia, no así para modificar las actitudes hacia la misma. Una sola actividad no es suficiente para causar el cambio deseado. Es indispensable la colaboración de los sectores que pueden ayudar a los jóvenes a adoptar nuevas figuras de autoridad que rechacen la violenci(AU)


Introduction: training of young people in the violence content may improve their relationship with parents, teachers and friends. Objective: to evaluate a health education intervention about violence and its consequences for adolescents. Methods: Evaluative research conducted in 2013 in 23 students with violence problems, who are studying at intermediate grades of a public school in Porto Rico. The first segment of intervention made emphasis on the cognitive aspects whereas the second one used a motivational strategy to modify attitudes towards violence. Before and after the intervention, a questionnaire was provided, which was based on the Knowledge, Attitudes and Practices for the Prevention of Violence Model. Results: in the sample, 52.17 percent (n= 12) were females and the average age of participants was 14 ± 1.51 years. After the intervention, 56.53 percent (n= 13) proved to have good knowledge about violence and 47.05 percent (n= 8) had positive attitude toward violence. The intervention managed to change the level of knowledge (U= -2.178, p= 0.03) but no significant difference was observed about attitudes toward violence in the participants (U=-1.124, p= 0.26). Conclusions: the intervention is effective in terms of increasing knowledge about violence rather than modifying positive attitude toward it. Just one activity is not enough to bring about the desired change. It is then indispensable to encourage the cooperation among the sectors that might help the young people to adopt new authoritative attitudes that reject violence(AU)

RESUMO

Introducción A los efectos de valorar los abordajes quirúrgicos de los vasos subclavios se debe tener en cuenta en primera instancia la disposición y relaciones anatómicas de la región a fin de disminuir los eventos adversos de procedimientos quirúrgicos tanto menores como mayores en la sala de urgencias. La región anatómica del cuello cuenta con elementos nobles de importancia vital. Resulta inabarcable la región a abordar, por lo que es menester delimitarla de manera más específica utilizando reparos anatómicos fácilmente identificables. Objetivos: Es objetivo del siguiente trabajo delimitar zonas de fácil y rápido acceso para el abordaje de los vasos subclavios. Material y Método: se utilizaron n=30 preparaciones cadavéricas formolizadas las cuales fueron disecadas en un periodo comprendido entre marzo hasta septiembre de 2016. Luego del periodo de disección se procedió a un periodo demostración y aprendizaje donde 10 residentes de cirugía general fueron evaluados en cuanto a sus conocimientos anatómicos. En el siguiente periodo fueron abordados 10 vasos subclavios en preparaciones cadavéricas frescas tomándose en cuenta el tiempo utilizado para el abordaje. Se estableció un tiempo límite de 2 minutos 30 segundos. Los residentes que obtuvieron un promedio de tiempo mayor repitieron la etapa de mostración y aprendizaje hasta mejorar el tiempo estipulado. Resultados: El correcto abordaje de los vasos subclavios con el entrenamiento previo proporciona al paciente un escenario de seguridad. El compromiso de los vasos subclavios en la sala de urgencias requiere un abordaje preciso en el menor tiempo posible ya que su lesión es de compromiso vital. Conclusiones: El abordaje de los vasos subclavios en el cuello resulta de especial interés en el sistema de formación de residentes de cirugía general. La incorporación de modelos cadavéricos para la adquisición de habilidades en el control vascular de los vasos subclavios disminuye la morbimortalidad de los pacientes con lesión de los vasos en la sala de urgencias.


Introduction: In order to appreciate subclavian vessels approaches, we should keep in mind in first instance the disposition and anatomical relations of the region in order to reduce adverse effects of surgical procedements, both minor and major at the emergency room. The anatomical region of the neck has noble elements of vital importance. The region to be addressed results unreachable, so it is necessary to delimit it in a specific way using anatomical repairs easily identifiable. Objectives: The objective of the following work is to delimit zones of easy and quick access to approach subclavian vessels. Material and method: we used n: 30 formaldehyde cadaveric preparations which were dissected in a period from march to September 2016. After The dissection period, a period of demonstration and learning was carried out, where 10 General surgery residents were evaluated on their anatomical knowledge. In The following period, ten subclavian vessels were approached in fresh cadaveric preparations taking on account the time used for the boarding. Time Limit of 2 Minutes and 3 Seconds was set. The Residents who obtained a longer average time, repeated the demonstration and learning stage until the stipulated time was improved. Results: The correct approach of subclavian vessels with previous training provides a safe scenary for the patient. The Commitment of the subclavian vessels in emergency room requires the shortest possible time to approach it, cause its injury is vital. Conclusions: The Approach of subclavian vessels in neck is the special interest for training residents of general surgery. The incorporation of Cadaveric models for the acquisition of skills in vascular control of subclavian vessels, decreases the morbidity and mortality of patients with vessel injury in the emergency room.

RESUMO

The DEAD box RNA helicase DDX5 is a multifunctional protein involved in the regulatory events of gene expression. Herein, we presented evidence indicating that DDX5 is transcriptionally upregulated by calcitriol, the hormonal form of vitamin D3. In silico analysis revealed the presence of two putative vitamin D response elements (VDREs) in the DDX5 promoter region. Using luciferase reporter assays, we demonstrated that the DDX5 promoter containing these putative VDREs significantly increased the luciferase activity in vitamin D receptor (VDR)-positive SiHa cells upon calcitriol treatment. Electrophoretic mobility shift assays showed the ability of VDR and retinoid X receptor to interact only with the most proximal VDRE, while chromatin immunoprecipitation analysis confirmed the occupancy of this VDRE by the VDR. Finally, we demonstrated that calcitriol significantly increased both DDX5 mRNA and protein in SiHa cells. In summary, this study shows that DDX5 gene is transcriptionally upregulated by calcitriol through a VDRE located in its proximal promoter. Given the importance of DDX5 as a master regulator of differentiation programs, our study suggests that the pro-differentiating properties of calcitriol may be related with the induction of DDX5.
