5-Year management and outcomes of penetrating neck injury in a trauma center. Penetrating neck injury / Manejo y resultados de trauma penetrante de cuello en 5 años dentro de un centro de urgencias. Trauma penetrante de cuello

Background Penetrating neck injuries represent 5–10% of all traumatic injuries, these bring with them a high rate of morbidity and mortality due to vital structures that could be injured in this area. The aim of this study was to determine the epidemiological and clinical characteristics of penetrating neck injuries. Methods This was a retrospective, unicentric and descriptive study that included all patients who underwent neck exploration surgery. Results A total of 70 neck exploration cases were reviewed, 34 (49%) didn’t had any injury. Thirty (43%) had at least one hard sign, 42 (60%) patients showed at least one soft sign. Statistical analysis showed only surgical time (252±199.5 vs. 155±76.4; p=0.020) and transfusions (1.87±3 vs. 0.4±0.856; p=0.013) were statistically significant. We report a mortality of 2 (3%) patients. Conclusions Our prevalence of neck surgical exploration without vascular injury was slightly higher (49% vs. 40%) than literature. We highlight the importance of not performing neck explorations in all patients who present a penetrating injury. We did not obtain differences between groups for hard signs and soft signs. We were not able to identify whether or not there would be an injury based on clinical characteristics. Imaging studies should be performed to avoid unnecessary neck explorations; however, depending on the clinical scenario some surgery cannot be avoided (AU)

Antecedentes Las lesiones penetrantes de cuello representan entre el 5-10% de todas las lesiones traumáticas, estas traen consigo una alta tasa de morbimortalidad por estructuras vitales que podrían lesionarse en esta área. El propósito de este estudio fue determinar las características epidemiológicas y clínicas del trauma penetrante de cuello. Métodos Estudio retrospectivo, unicéntrico y descriptivo que incluyó a todos los pacientes sometidos a cirugía de exploración de cuello. Resultados Se revisaron un total de 70 casos de exploración de cuello, 34 pacientes (49%) no presentaron ninguna lesión. Treinta pacientes (43%) tenían al menos un signo duro, 42 pacientes (60%) mostraron al menos un signo blando. El análisis estadístico mostró que solo el tiempo quirúrgico (252±199,5 vs. 155±76,4; p=0,020) y las transfusiones (1,87±3 vs, 0,4±0,856; p=0,013) fueron estadísticamente significativas. Reportamos la mortalidad de 2 pacientes (3%). Conclusiones Nuestra prevalencia de exploración quirúrgica de cuello sin lesión vascular fue ligeramente superior (49 vs. 40%) que la literatura. Destacamos la importancia de no realizar exploraciones de cuello en todos los pacientes que presentan una lesión penetrante. No obtuvimos diferencias entre grupos para signos duros y signos blandos. No pudimos identificar si hubiera o no una lesión en función de las características clínicas. Se deben realizar estudios de imagen para evitar exploraciones innecesarias del cuello; sin embargo, dependiendo del escenario clínico, no se pueden evitar algunas cirugías (AU)

[Functional evaluation with the KSS (Knee Society Score) scale at 3 and 6 months after ligament reconstruction in patients with multi-ligament knee injuries in a third level hospital]. / Evaluación funcional con la escala KSS (Knee Society Score) a tres y seis meses de la reconstrucción ligamentaria en pacientes con lesiones multiligamentarias de rodilla en un hospital de tercer nivel.

Multiligament injuries of the knee joint are characterized by the involvement of two or more major ligaments, anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), lateral collateral ligament (LCL), posteromedial corner (PMC) and posterolateral corner (PLC). Statistically, multiligament injuries are rare as they are found in less than 0.02% of all traumatic knee injuries; however, different aggregate injuries are what make this pathology a serious health and functional condition. Taking into account that most of the patients are young people of highly productive age, it is of vital importance to observe their short and long term evolution, as well as their reincorporation to their daily life. It has been reported that vascular lesions are present in approximately 32% of cases, meniscal lesions in 35% and up to 60% with some type of bone lesion. These injuries mainly affect the male sex most commonly between the third and fourth decade of life, which makes this type of injury of great importance, since this group of patients are in their greatest period of labor production. The main objective of the treatment of these injuries, in addition to resolving the aggregate damage that usually aggravates the state of health, is to achieve a speedy recovery and subsequent reincorporation to their work activities and in some cases sports.

Las lesiones multiligamentarias de la articulación de la rodilla se caracterizan por la afección de dos o más ligamentos principales, ligamento cruzado anterior (LCA), ligamento cruzado posterior (LCP), ligamento colateral medial (LCM), ligamento colateral lateral (LCL), esquina posteromedial (EPM) y esquina posterolateral (EPL). Estadísticamente, las lesiones multiligamentarias son poco frecuentes, ya que se encuentran en menos de 0.02% de todas las lesiones traumáticas de rodilla; sin embargo, diferentes lesiones agregadas son las que hacen de esta patología un estado grave para salud y funcionalidad. Tomando en cuenta que la mayoría de los pacientes son personas jóvenes en edad altamente productiva, es de vital importancia observar la evolución de los mismos a corto y largo plazo, así como su reincorporación a su vida cotidiana. Se ha descrito que las lesiones vasculares se presentan aproximadamente en 32% de los casos, lesiones meniscales en 35% y hasta 60% con algún tipo de lesión ósea. Estas lesiones afectan principalmente al sexo masculino con más frecuencia entre la tercera y cuarta década de la vida, lo cual hace a este tipo de lesiones de gran importancia, ya que este grupo de pacientes se encuentran en su mayor período de producción laboral. El objetivo principal del tratamiento de estas lesiones, además de resolver los daños agregados que suelen ser los agravantes del estado de salud, es lograr una pronta recuperación y posterior reincorporación a sus actividades laborales y en algunos casos deportivas.

Sweet corn cob as a functional ingredient in bakery products.

Gluten free (GF) products are often inferior in quality attributes, nutritional content and consumer acceptability. The use of GF by-products is a novel strategy to improve the structure and nutritional profile of these products. Sweet corn cob (SCC) is a by-product of sweet corn processing containing a considerable amount of fibre and ferulic acid. The effect of baking on ferulic acid content, colour, texture and physical characteristics on muffins incorporated with SCC flour (SCCF) as a value-added food ingredient was investigated using a GF model system. The freeze-dried SCCF, containing ferulic acid (6.02 mg g-1) was used to replace the rice flour at varying levels of 10, 20, and 30%. In general, SCCF increased dietary fibre and free ferulic acid content of muffins. Inclusion of 20% SCCF showed an increase in terms of the height of the muffin and number of air cells in the crumb, along with a decrease in the hardness of muffins. Muffins with SCCF showed higher mean overall liking scores than rice flour muffin.

Transanal endoscopic surgery with a 3D printed device.

BACKGROUND: The aim of this study was to investigate the effectiveness of devices manufactured with 3D printing for performing transanal endoscopic procedures without pneumorectum. METHODS: Functional devices were designed in the Polytechnic School of Engineering of Gijón from 2016 to 2018 using three-dimensional (3D) solid modelling software (Solid-Works®), that allows customization of the device (diameter and length). The devices were made in acrylonitrile butadiene styrene (ABS) by additive manufacturing using an HP Designjet 3D Printer, with fused deposition modelling (FDM) technology. Tests were carried out on mixed simulators (with viscera) and cadavers with a prototype in the form of an open cylindrical base ellipsoid spindle with two bars. In this paper, we present the information of the first series of patients in which this device has been used to perform a full-thikness endoscopic resection of the rectal wall without pneumorectum. The characteristics of the patients, size, and location of the lesion, the type of anesthesia used, the duration of the procedure, hospital stay, complications, and pathology were analyzed. An endoscopic follow-up was also carried out for at least 2 years. RESULTS: Seven interventions were carried out in six patients. The lesions were located at a mean distance of 5 cm from the anal verge and an average area of 11.8 cm2. Four of the procedures were performed with general anesthesia and 3 with spinal anesthesia. Histopathology examination identified 3 adenomas, 3 pT1 and 1 pT2 adenocarcinomas. All excisions were full thickness. En bloc excision was possible in all cases. In only one case of a benign polyp there was a positive lateral margin. As regards complications, there was one case of postoperative rectal bleeding without the need for transfusions. There were no readmissions and no postoperative mortality. CONCLUSIONS: An innovative device made with a 3D printer can be used successfully in transanal endoscopic resections of the rectal wall, with spinal anaesthesia and avoiding the need for pneumorectum.

Numerical Model to Analyze the Physicochemical Mechanisms Involved in CO2 Absorption by an Aqueous Ammonia Droplet.

CO2 is the main anthropogenic greenhouse gas and its reduction plays a decisive role in reducing global climate change. As a CO2 elimination method, the present work is based on chemical absorption using aqueous ammonia as solvent. A CFD (computational fluid dynamics) model was developed to study CO2 capture in a single droplet. The objective was to identify the main mechanisms responsible for CO2 absorption, such as diffusion, solubility, convection, chemical dissociation, and evaporation. The proposed CFD model takes into consideration the fluid motion inside and outside the droplet. It was found that diffusion prevails over convection, especially for small droplets. Chemical reactions increase the absorption by up to 472.7% in comparison with physical absorption alone, and evaporation reduces the absorption up to 41.9% for the parameters studied in the present work.

Recomendaciones para la vacunación en pacientes con esclerosis múltiple candidatos a terapias inmunosupresoras: documento de consenso español / Recommendations for vaccination in patients with multiple sclerosis who are eligible for immunosuppressive therapies: Spanish consensus statement

ANTECEDENTES: La reciente aparición de terapias de alta efectividad para el tratamiento de la esclerosis múltiple (EM), con potencial riesgo de complicaciones infecciosas, obliga plantear estrategias de prevención y minimización de riesgos. La vacunación constituye una parte esencial del manejo de estos pacientes. Este consenso recoge una serie de pautas y escenarios prácticos de vacunación en pacientes adultos con EM candidatos a tratamiento inmunosupresor. METODOLOGÍA: Se llevó a cabo un consenso de tipo formal. Tras definir el alcance del documento, se realizó una búsqueda bibliográfica de vacunación en pacientes con EM, así como guías de vacunación específicas de pacientes inmunosuprimidos y en tratamiento biológico con otras enfermedades. Para la formulación de las recomendaciones se empleó la metodología de Modified Nominal Group Technique. DESARROLLO: La vacunación en pacientes candidatos a tratamiento inmunosupresor se debe plantear antes de iniciar un tratamiento inmunosupresor siempre que la situación clínica del paciente lo permita. Se recomendarán tanto aquellas indicadas en el calendario vacunal del adulto, como algunas específicas, en función de la inmunidad previa. Si ya está instaurado el tratamiento inmunosupresor las vacunas vivas atenuadas estarán contraindicadas. Para aquellas vacunas que dispongan de un correlato de protección se recomienda monitorizar la respuesta serológica transcurridos de uno a 2 meses de la última dosis

BACKGROUND: The recent development of highly effective treatments for multiple sclerosis (MS) and the potential risk of infectious complications require the development of prevention and risk minimisation strategies. Vaccination is an essential element of the management of these patients. This consensus statement includes a series of recommendations and practical scenarios for the vaccination of adult patients with MS who are eligible for highly effective immunosuppressive treatments. METHODOLOGY: A formal consensus procedure was followed. Having defined the scope of the statement, we conducted a literature search on recommendations for the vaccination of patients with MS and specific vaccination guidelines for immunosuppressed patients receiving biological therapy for other conditions. The modified nominal group technique methodology was used to formulate the recommendations. DEVELOPMENT: Vaccination in patients who are candidates for immunosuppressive therapy should be considered before starting immunosuppressive treatment providing the patient's clinical situation allows. Vaccines included in the routine adult vaccination schedule, as well as some specific ones, are recommended depending on the pre-existing immunity status. If immunosuppressive treatment is already established, live attenuated vaccines are contraindicated. For vaccines with a correlate of protection, it is recommended to monitor the serological response in an optimal interval of 1-2 months from the last dose

Experimental lateral wall boundary layer behavior of a differentially rotating split-cylinder flow.

The cylindrical wall boundary layer of a closed cylinder split in two halves at the equator is studied experimentally. When these two parts rotate in exact corotation the internal flow is essentially in solid-body rotation at the angular velocity of both halves. When a slight difference between the rotation frequencies is established a secondary flow is created due to the differential rotation between both sides and restricted to the boundary layer. This behavior of the boundary layer is compared with theoretical and numerical results finding the "sandwich" structure of a Stewartson boundary layer. Time-dependent waves are observed near the cylindrical wall. Their behavior for different values of the control parameters are presented. Finally, a global recirculation mode is also found due to a symmetry-breaking induced between sides that appears because of a slight misalignment of the experimental setup, whose characteristics are compatible with the behavior of a precessing cylinder.

Introducción. La escoliosis idiopática del adolescente (EIA) es un problema de salud crónico en el que las deformidades y el tratamiento ortésico que precisan en algunos casos pueden afectar negativamente a la calidad de vida de estos pacientes, más aun teniendo en consideración la difícil etapa en la que se encuentran. Objetivo. Creación de una escuela de escoliosis (EE) para intentar mejorar la información que reciben los pacientes con EIA y sus familiares sobre la deformidad, la evolución y los posibles tratamientos, intentando favorecer una mayor adherencia a las terapias y una mejora en su calidad de vida. Material y método. Creación de una EE para pacientes y sus familiares. Estudio cuasi-experimental antes-después de pacientes con EIA que inician tratamiento ortésico durante el año 2015. Evaluamos la escala de conocimientos acerca de la deformidad, la calidad de vida percibida mediante el perfil CAVIDRA y la satisfacción global. Resultados. Un total de 29 pacientes han asistido a la EE; de ellos, 22 eran niñas con una edad media de 12,82±3,72 años. El corsé más utilizado ha sido el Chêneau. Tanto el cuestionario sobre conocimientos como el perfil CAVIDRA mejoraron tras la EE. La satisfacción con el proceso global de información ha sido mayor de 8 en todos los ítems. Conclusiones. La EE puede ser una importante herramienta informativa en pacientes con escoliosis idiopática del adolescente, dada la edad vulnerable que presentan y la complejidad del tratamiento ortésico. Esta herramienta parece mejorar el nivel de conocimientos de la deformidad, la adherencia al corsé y la calidad de vida percibida (AU)

Introduction. Adolescent idiopathic scoliosis (AIS) is a chronic health problem in which trunk deformities and the necessary brace treatment can sometimes negatively affect adolescents’ quality of life, especially given the difficulties of this stage of life. Objective. To create a scoliosis school (SS) in order to improve the information received by AIS patients and their familiars about the deformity, its natural history and possible treatments, as well as to encourage treatment adherence and improve quality of life. Material and method. Creation of an SS for patients and their families. This was a before-after quasi-experimental study of patients with AIS who began brace treatment during 2015. We evaluated knowledge about the deformity, self-perceived quality of life assessed by the CAVIDRA profile and global satisfaction. Results. A total of 29 patients have attended the SS; of these, 22 were girls with a mean age of 12.82±3.72 years. The most commonly used brace was the Chêneau brace. Both the knowledge questionnaire and CAVIDRA scale scores improved after attendance at the SS. Satisfaction with the global information process was above 8 in all items. Conclusions. The SS could be an important information tool in AIS patients due to their vulnerable age and the complexity of brace treatment, improving their knowledge about the deformity, as well as their quality of life and treatment adherence (AU)

Epidemiología y evolución perioperatoria de lesión vascular periférica en civiles por trauma penetrante durante una década / Epidemiology and outcomes for civilian peripheral vascular injury in penetrating trauma during a decade

Introducción: Las lesiones causadas por trauma penetrante son una de las principales causas de morbimortalidad en todo el mundo. Para una gestión eficiente y un tratamiento adecuado, es esencial lograr una rápida detección, localización y caracterización de la lesión. Objetivo: Determinar la epidemiología y revisar el manejo perioperatorio de lesiones vasculares periféricas en extremidades durante una década. Material y métodos: Se utilizaron datos de 2006-2015 de un hospital universitario con pacientes con diagnóstico de lesión vascular en extremidades. Resultados: Se reportó un total de 110 casos. En 26 de los pacientes (23,6%) la lesión fue causada por una herida por arma punzo cortante y en 84 pacientes (76,4%) por proyectil de arma de fuego. El sitio lesionado más común fue la extremidad inferior. Veintiséis pacientes (23,6%) no mostraron lesión durante la angiografía. Se identificaron un total de 150 lesiones vasculares. Conclusiones: La arteria más comúnmente lesionada fue la femoral. Los factores predictivos de las lesiones estadísticamente significativos fueron la puntuación de la gravedad de la lesión, el grado de choque y los pacientes con lesiones múltiples. Seis amputaciones reportadas coinciden con un trauma severo. La ausencia de signos duros no descarta la posibilidad de lesión arterial. Se recomienda la reparación con injerto de safena invertido para las lesiones no reparables de manera primaria (AU)

Background: Penetrating trauma injuries are a leading cause of morbidity and mortality worldwide. For efficient management and appropriate treatment, the injuries need to be rapidly detected, located, and characterised. Objective: To describe the epidemiology and review the management of vascular injuries over a 10-year period. Material and methods: Data were used from patients with a diagnosis of vascular injury in extremities between 2006 and 2015 from a university hospital. Results: A total of 110 cases were reported. In 26 (23.6%) patients the injury was caused by a stab wound, and by a gunshot wound in 84 (76.4%) patients. The most common injury site was the lower limb. Twenty-six (23.6%) patients showed no injury in the angiography. A total of 150 vascular injuries were identified. Conclusion: The most commonly injured artery was the femoral. Statistically significant injury predictive factors were the injury severity score, the degree of shock, and patients with multiple injuries. Six amputations reported were associated with severe trauma. The absence of severe signs does not rule out the possibility of arterial injury. Inverted saphenous vein graft repair is recommended for non-repairable injuries (AU)

Clinical residual symptomatology and associated factors in multiple organ failure survivors: A long-term mortgage. / Sintomatología clínica residual y factores asociados en supervivientes de un fracaso multiorgánico: una hipoteca a largo plazo.

PURPOSE: To evaluate which residual clinical symptoms multi-organ failure (MOF) patients may exhibit post discharge from Intensive Care Units (ICU) and to identify the associated factors that cause such symptoms. MATERIAL AND METHODS: A total of 545 adult patients admitted to a medical & surgical ICU in Spain diagnosed with MOF on admission were included in the study. Follow up in the form of a telephone survey regarding the patients clinical symptoms were conducted at 6 and 12 months after discharge from ICU. RESULTS: A total of 266 patients were followed up at both 6 and 12 months post ICU discharge; 62.2% were male; age 60±18 years; 67.8% medical patients. The most common symptoms to appear following hospital discharge included: asthenia (173; 76%), sleep disturbances (112; 50%) and depression (109; 48%). CONCLUSIONS: The study revealed frequent residual clinical symptoms persisting for almost a year post ICU discharge, most notably arthromyalgia and asthenia. Depression symptoms during the first 6 months post-hospital discharge were also common among multiple organ failure survivors. The presence of symptomatology over time was found to be related to a poor functional situation at 6 and12 months post ICU discharge, length of hospital stay and severity of illness score on ICU admission.
