Análisis del tratamiento del prolapso de órganos pélvicos mediante colposacropexia mínimamente invasiva con 24 horas de ingreso / Analysis of minimally invasive sacrocolpopexy with 24-hour hospital stay for the treatment of pelvic organ prolapse

Objetivos: El objetivo del presente estudio es analizar el resultado de la implementación de una vía clínica para la corrección del prolapso de órganos pélvicos mediante colposacropexia mínimamente invasiva (CSMI) con 24 horas de ingreso en términos de seguridad y ahorro de costes de hospitalización. Material y métodos: Estudio observacional prospectivo de los primeros 78 procedimientos de CSMI realizados de forma consecutiva. Cuarenta y seis procedimientos (59%) se realizaron con estancia hospitalaria de 24 horas, mientras que 32 (41%) precisaron más de 24 horas. Para cada grupo se determinaron las complicaciones postoperatorias, visitas al servicio de urgencias, reintervenciones y el coste medio por procedimiento en términos de estancia hospitalaria y atención en el Servicio de Urgencias. El modelo de costes se estableció según los datos del Sistema de Contabilidad Analítica del Hospital Fundación Jiménez Díaz y del Boletín oficial de la Comunidad de Madrid. Resultados: No se encontraron diferencias entre ambos grupos respecto a las complicaciones intraoperatorias o postoperatorias. Las consultas en el servicio de urgencias, reintervenciones o reingresos hospitalarios fue menor en el grupo de 24 horas de ingreso, sin alcanzar la significación estadística. Mediante la implementación de la vía clínica de CSMI con 24 horas de ingreso se objetivó un ahorro de 607,91 € por procedimiento en estancia hospitalaria. Conclusiones: La corrección del prolapso de órganos pélvicos mediante CSMI con política de alta hospitalaria de 24 horas es factible y segura en al menos el 59% de las pacientes, sin objetivarse un mayor número de complicaciones, visitas al servicio de urgencias o reingresos hospitalarios

Objectives: The objective of this study is to analyze the impact (in terms of safety and saving of hospital costs) of the implementation of a new protocol for the correction of pelvic organ prolapse (POP) by minimally invasive sacrocolpopexy (MISC) with 24-hour hospital stay. Material and methods: Prospective observational study of the first 78 MISC procedures performed consecutively. 46 procedures (59%) were performed with 24-hour hospital stay, and 32 (41%) required more than 24 hours. The postoperative complications were determined for each group: visits to the Emergency Department, reoperations, and the average cost per procedure regarding hospital stay and ER visits. The cost model was established according to the data of the Analytical Accounting System of the Jiménez Díaz Foundation Hospital and of the Official State Gazette of Madrid. Results: There were no differences regarding intraoperative or postoperative complications between both groups. The number of visits to the Emergency Department, reinterventions or hospital re-admissions was lower in the 24-hour hospital stay group, without reaching statistical significance. The implementation of the MISC protocol with 24-hour hospital stay represented a saving of 607.91 € per procedure in hospital costs. Conclusions: Correction of the POP with MISC with a 24-hour hospital discharge policy was feasible and safe in at least 59% of the patients, with similar complications, visits to the Emergency Department or hospital readmission rates

Análisis de costes del tratamiento del prolapso de órganos pélvicos mediante colposacropexia laparoscópica o malla transvaginal / Cost analysis of surgical treatment for pelvic organ prolapse by laparoscopic sacrocolpopexy or transvaginal mesh

Objetivos. El objetivo del estudio es realizar un análisis comparativo de los costes directos de la reparación del prolapso de órganos pélvicos mediante colposacropexia laparoscópica (CL) o malla transvaginal (MTV). La hipótesis inicial es que la corrección del prolapso de órganos pélvicos mediante CL presentaría al menos un coste por procedimiento similar a la corrección mediante MTV. Material y métodos. Análisis retrospectivo comparativo del coste medio por procedimiento de los primeros 69 procedimientos consecutivos de CL frente a los primeros 69 procedimientos consecutivos de MTV. Para cada procedimiento, se determinaron los costes directos: gastos estructurales, personal, ocupación de quirófano, estancia hospitalaria, material fungible e inventariable y el material protésico implantado. Se determinó el coste medio por procedimiento para cada uno de los grupos, con el intervalo de confianza al 95%. Resultados. Mientras que el grupo de CL incurrió en un mayor gasto en relación con un mayor tiempo quirúrgico, ocupación de quirófano y anestesia, el grupo de MTV incurrió en un mayor gasto en relación con una mayor estancia hospitalaria y un coste mayor del material protésico implantado. De forma global, si bien el grupo de CL presentó un coste medio por procedimiento menor que el grupo de MTV (5.985,7 Euros ± 1.550,8 Euros vs. 6.534,3 Euros ± 1.015,5 Euros), esta diferencia no alcanzó la significación estadística. Conclusiones. En nuestro medio, la corrección del prolapso de órganos pélvicos mediante CL presenta al menos, un coste por procedimiento similar a la corrección del mismo mediante MTV (AU)

Objectives. The objective of this study is to compare direct costs of repairing pelvic organ prolapse by laparoscopic sacrocolpopexy (LS) against vaginal mesh (VM). Our hypothesis is the correction of pelvic organ prolapse by LS has a similar cost per procedure compared to VM. Material and methods. We made a retrospective comparative analysis of medium cost per procedure of first 69 consecutive LS versus first 69 consecutive VM surgeries. We calculate direct cost for each procedure: structural outlays, personal, operating room occupation, hospital stay, perishable or inventory material and prosthetic material. Medium cost per procedure were calculated for each group, with a 95% confidence interval. Results. LS group has a higher cost related to a longer length of surgery, higher operating room occupation and anesthesia; VM group has a higher cost due to longer hospital stay and more expensive prosthetic material. Globally, LS has a lower medium cost per procedure in comparison to VM (5,985.7 Euros ± 1,550.8 Euros vs. 6,534.3 Euros ± 1,015.5 Euros), although it did not achieve statistical signification. Conclusions. In our midst, pelvic organ prolapse surgical correction by LS has at least similar cost per procedure compared to VM (AU)

Machine perfusion: initial results in an expanded criteria donor kidney transplant program.

BACKGROUND: Delayed graft function (DGF) negatively impacts graft survival. Expanded criteria donors (ECD) show a higher rate of DGF. Hypothermic machine perfusion (HMP) has shown a DGF decrease and an increase of survival at 1 year. Several authors found that renal resistance (RR) at the end of machine perfusion was an independent risk factor for the development of DGF and poorer graft survival. The objective of this study was to analyze HMP results in the context of an ECD program and assess the impact of donor parameters and resistance index (RI) during perfusion in graft survival after kidney transplantation. METHODS: Donor age, terminal creatinine, machine perfusion time, percentage of glomerulosclerosis, and RI at the end of the perfusion were considered as risk predictors. Univariate and multivariate Cox regression analysis was constructed to find independent risk factors of DGF. Finally, diagnostic validity for RR was determined by sensitivity, specificity, and positive and negative predictive values. RESULTS: Twenty-three percent of patients developed DGF. We found no difference in the ability of flow or RI to predict the development of DGF. The predictive accuracy of RI for DGF by receiver operator characteristic curve was poor, with a c-statistic of 0.66 (95% CI, 0.50-0.81; P = .046). Our analysis did not identify risk factors that predicted graft survival at 1 year. Patient and graft survival were 98.8% and 89.7%, respectively. CONCLUSIONS: HMP has reduced the rate of DGF in our cohort of recipients of ECD grafts compared with historical data (23.3% vs 38.0%). Analysis did not identify risk pretransplant factors for graft survival at 1 year.

Resistance index determination in the pre and post kidney transplantation time points in graft dysfunction diagnosis.

BACKGROUND: Donor shortage necessitates the development of tools capable of objectively assessing kidney graft quality from expanded criteria donors and kidneys donated after cardiac death. The deteriorating donor profile is leading to a shift from cold storage toward machine perfusion preservation. Several authors found that renal resistance (RR) at the end of machine perfusion was an independent risk factor for the development of delayed graft function (DGF). In contrast, Doppler ultrasonography in the posttransplant period reveals renal hemodynamics and is useful in diagnosing renal allograft dysfunction. We sought to determine concordance between RR and the resistance index (RI) and their diagnostic value in the assessment of graft viability. METHODS: RR was determined at the end of perfusion during hypothermic machine preservation and RI was measured by Doppler ultrasonography in the early posttransplant period. Agreement between these 2 measures was established by means of the intraclass correlation coefficient (ICC). Diagnostic validity for RR and RI was determined by sensitivity, specificity and positive and negative predictive values. RESULTS: The ICC was 0.135, which indicates a slight agreement. RR and RI had limited value in the prediction of DGF for a specific kidney as reflected by a c-statistic of 0.58 and 0.66, respectively. CONCLUSIONS: There is no agreement between the RR and RI, which may be owing to the different conditions under which measurements are made. The poor predictive power of RR for DGF indicates that kidneys should not be discarded based on RR criteria alone.

Análisis coste-efectividad de las principales herramientas diagnósticas en mujeres con vejiga hiperactiva: historia clínica, diario miccional y estudio urodinámico / Cost-effectiveness analysis of main diagnosis tools in women with overactive bladder. Clinical history, micturition diary and urodynamic study

Objetivos: El presente trabajo de investigación clínica pretende analizar a la luz de la mejor evidencia científica el rendimiento y el coste de las principales herramientas utilizadas en el diagnóstico de la vejiga hiperactiva (VH). Métodos: Se trata de un estudio transversal exploratorio y analítico, en el cual se seleccionó una muestra de 199 mujeres diagnosticadas de VH entre los años 2006 y 2008, a las que se realizó de forma prospectiva: exploración física, análisis de orina, diario miccional (DM) y estudio urodinámico (EUD). Se asumió que un porcentaje de diagnóstico altamente sensible debería ser 80% y que una diferencia de diagnóstico del 10% entre las pruebas sería clínicamente relevante. Se determinó estadísticamente la sensibilidad de cada una de las pruebas de forma aislada y combinada para el diagnóstico de VH y una valoración de los recursos económicos directos e indirectos que conlleva su realización, analizándose el coste efectividad de la historia clínica (HC), DM y EUD para el diagnóstico de VH. Resultados: La sensibilidad global para el diagnóstico de VH es baja para cualquiera de las pruebas utilizadas de forma aislada, mientras que la combinación de 2 pruebas cualesquiera presenta una buena sensibilidad global para su diagnóstico. La combinación de HC y DM es la alternativa más coste efectiva en el diagnóstico de VH. Conclusiones: El uso de HC y DM es una combinación tan sensible para el diagnóstico de la VH como la asociación de cualquiera de ellas con el EUD, presentando además un menor coste económico

Objetives: The aim of the present clinical research is to analyze, in the light of the best scientific evidence, the performance and the cost of the main diagnostic tools for overactive bladder (OAB). Methods: It is an exploratory transversal study in which 199 women diagnosed of OAB between 2006 and 2008 were selected and underwent to following prospective analyses: physical examination, urine analysis, micturition diary (MD) and urodynamic study (UDS). A percentage of 80% was assumed as highly sensitive and a diagnostic difference among tests of 10% would be considered clinically relevant. Tests’ sensitivity for diagnosis of OAB was statistically established by two ways: isolated and combined. Besides, the direct and indirect costs of these tests performance were conducted. Cost-effectiveness study of clinical history (CH), MD and US for the diagnosis of OAB was performed. Results: Overall sensitivity for OAB diagnosis is low for the 3 tests used in isolated way, whilst the combination of any two tests shows good overall sensitivity. The combination of CH and MD has appeared as the most cost-effective alternative to OAB diagnosis. Conclusions: For OAB diagnosis, CH-DM combination shows the same sensitivity than the association of either of them with the UDS, but unlike to these, it shows the lowest cost

Validation of a questionnaire on emotional eating for use in cases of obesity: the Emotional Eater Questionnaire (EEQ).

INTRODUCTION: Emotions have a powerful effect on our choice of food and eating habits. It has been found that in some people there is relationship between eating, emotions and the increased energy intake. This relationship should be measurable to better understand how food is used to deal with certain mood states and how these emotions affect the effectiveness of weight loss programs. OBJECTIVE: To develop and analyze the psychometric characteristics of a questionnaire on emotional eating for obesity easy to apply in clinical practice. SUBJECTS AND METHODS: A ten-item questionnaire called Emotional-Eater-Questionnaire (EEQ) was developed and administered to a total of 354 subjects (body mass index, 31 ± 5), aged 39 ± 12, who were subjected to a weight-reduction program. The questionnaire was specifically designed for obesity. Analysis of the internal structure, internal consistency, test-retest reliability and convergent validity with Mindful-Eater-Questionnaire (MEQ) were conducted. RESULTS: After principal components analysis, the questionnaire was classified in three different dimensions that explained 60% of the total variance: Disinhibition, Type-of-food and Guilt. Internal consistency showed that Cronbach's alpha was 0.773 for the "Dishinibition" subscale, 0.656 for the "Type of food" subscale and 0.612 for the "Guilt" subscale. The test-retest stability was r = 0.70. The data showed that the percentage of agreement between the EEQ and the MEQ was around 70% with a Kappa index of 0.40; P < 0.0001. CONCLUSION: We have presented a new questionnaire, which classifies individuals as a function of the relation between food intake and emotions. Such information will permit personalized treatments to be designed by drawing up early strategies from the very beginning of treatment programmes.

Introducción: Las emociones tienen un poderoso efecto sobre la elección de alimentos y los hábitos alimentarios. Existe una relación entre comer, emociones y el aumento del aporte calórico. Esta relación debería ser medible para comprender mejor cómo utilizamos los alimentos en determinados estados de ánimo y cómo las emociones afectan a la eficacia de los programas de pérdida de peso. Objetivo: Desarrollar y analizar las características psicométricas de un cuestionario para identificar la ingesta emocional en la obesidad de fácil aplicación en la práctica clínica. Material y métodos: Se ha desarrollado y administrado un cuestionario de diez ítems llamado Cuestionario-de-Comedor-Emocional (CCE) a un total de 354 sujetos (Índice de Masa Corporal: 31 ± 5), (Edad: 39 ± 12 años), pertenecientes a un programa de reducción de peso. Se llevó a cabo un análisis de la estructura interna del cuestionario, de la consistencia interna, la fiabilidad testretest y la validez convergente con el Mindful-Eater-Questionnaire (MEQ). Resultados: El análisis de componentes principales del cuestionario encontró tres dimensiones diferentes que explicaban el 60% de la varianza: desinhibición, tipo de alimento y culpa. La consistencia interna mostró que el alfa de Cronbach fue de 0,773 para la subescala "Desinhibición", 0,656 para "Tipo de alimentos" y 0,612 para "culpa". La estabilidad test-retest fue de r = 0,70. Los datos mostraron que el porcentaje de acuerdo entre el CCE y MEQ era del 70% con un índice Kappa de 0,40, P < 0,0001. Conclusión: Hemos presentado un nuevo cuestionario, que clasifica a los individuos en función de la relación entre la ingesta de alimentos y las emociones. Esta información permitirá el diseño de tratamientos personalizados desde el inicio para la obesidad (AU)

Psychometric properties of the Perception of Teasing Scale in a Spanish adolescent sample: POTS-S.

The present study examines the psychometric properties of the Spanish version of the Perception of Teasing Scale (POTS-S). Participants were 1559 adolescents. They completed a translated version of the POTS and versions validated in Spanish population of the Rosenberg Self-Esteem Scale, the Body Dissatisfaction and Drive for Thinness subscales of the Eating Disorders Inventory-2, and the Children's Eating Attitudes Test. The results showed that the POTS-S retains the original structure of two factors, weight and competency, with satisfactory fit indices. The POTS-S constitutes a shorter questionnaire than the original version; specifically, it consists of 9 items instead of 11. The POTS-S showed good internal consistency and satisfactory test-retest stability. The relationship between the weight subscale and the variables related to eating and weight were statistically significant. As regards the competency subscale, the correlations were all lower than those for the weight subscale, except in the case of the self-esteem variable. The POTS-S showed good psychometric properties, indicating its suitability as an instrument for assessing the perception of teasing in Spanish adolescents.

Distinctive clinicopathological associations of amplification of the cortactin gene at 11q13 in head and neck squamous cell carcinomas.

Amplification of the 11q13 region is a prevalent genetic alteration in head and neck squamous cell carcinoma (HNSCC). We investigated the clinical significance of cortactin (CTTN) and cyclin D1 (CCND1) amplification in both malignant transformation and tumour progression. CTTN and CCND1 amplification was analysed by differential and real-time PCR in a prospective series of laryngeal/pharyngeal carcinomas and archival premalignant tissues. CTTN mRNA and protein expression were respectively determined by real-time RT-PCR and immunohistochemistry, and correlated with gene status. Molecular alterations were associated with clinicopathological parameters and disease outcome. CTTN and CCND1 amplifications were respectively found in 75 (37%) and 90 (45%) tumours. Both correlated with advanced disease; however, only CTTN amplification was associated with recurrence and reduced disease-specific survival (p = 0.0022). Strikingly, CTTN amplification differentially influenced survival depending on tumour site (p = 0.0001 larynx versus p = 0.68 pharynx) and was an independent predictor of reduced survival in the larynx (p = 0.04). CCND1 amplification was detected in early tumourigenesis and increased with the severity of dysplasia. Importantly, CTTN amplification was only found in high-grade dysplasias that progressed to invasive carcinoma. CTTN gene status strongly correlated with mRNA and protein expression. Furthermore, CTTN overexpression correlated significantly with reduced disease-specific survival (p = 0.018). Taken together, these data indicate that CTTN may serve as a valuable biomarker to identify patients with laryngeal tumours at high risk of recurrence and poor outcome.

[CCND1 gene amplification in the adenoid cystic carcinoma of the minor salivary glands]. / Amplificación del gen de la ciclina D1 en los carcinomas adenoides quísticos de glándulas salivares menores.

OBJECTIVE: Adenoid cystic carcinoma (ACC) is a tumour of epithelial origin that represents the most common malignant neoplasm of the minor salivary glands. However, little is known about the genes involved in the development and progression of this tumour. Cyclin D1 gene (CCND1) plays a key role in the control of the cell cycle, and its amplification is described in numerous cancers. The aim of this study is to determine the amplification of the CCND1 gene in the ACC of the minor salivary glands. MATERIALS AND METHODS: A retrospective study was performed on 12 patients with ACC of the head and neck. The amplification of the CCND1 was determined using multiple PCR. RESULTS: Amplification of the CCND1 was found in 4 patients (33.3%). No correlation was found between CCND1 amplification and clinicopathological parameters, although disease-free survival was diminished in patients with amplification. DISCUSSION/CONCLUSIONS: Our study demonstrates for the first time the amplification of the CCND1 gene in ACC. We have found an amplification rate similar to others neoplasms. CCND1 amplification seems to be associated with a poorer prognosis in these tumours, although this needs to be confirmed in larger studies.

Amplificación del gen de la ciclina d1 en los carcinomas adenoides quísticos de glándulas salivares menores / CCND1 gene amplification in the adenoid cystic carcinoma of the minor salivary glands

Introducción/Objetivo: El carcinoma adenoide quístico (CAQ) es un tumor de estirpe epitelial y representa el tumor maligno más frecuente de las glándulas salivares menores. Sin embargo, se conoce poco de los genes implicados en el desarrollo y progresión de estos tumores. El gen de la ciclina D1 (CCND1) juega un papel clave en el control del ciclo celular, y su anomalía está descrita en numerosos cánceres. El objetivo de este estudio es determinar si existe amplificación del CCND1 en los CAQ de glándulas salivares menores y su posible relación con el pronóstico. Material y métodos: Se realiza un estudio retrospectivo de 12 pacientes intervenidos de CAQ de fosas nasales y senos paranasales. Se determinó la existencia de amplificación del CCND1 mediante PCR múltiple. Resultados: Se encontró amplificación del CCND1 en 4 casos (33,3 por ciento). No se halló relación significativa con ninguno de los parámetros clínico-patológicos analizados (localización, tipo histológico, estadio; p>0,05). La supervivencia fue menor en los pacientes que presentaban amplificación de CCND1. Discusión/Conclusiones: Nuestro estudio es el primero que demuestra la amplificación del gen de la ciclina D1 en los CAQ. La amplificación del CCND1 parece tener relación con un peor pronóstico en estos tumores, aunque es necesario confirmar esta relación en estudios más amplios (AU)

[Detection of herpes simplex virus and Epstein-Barr virus in squamous cell carcinoma of the upper airways and digestive system]. / Detección del virus herpes simplex y del virus de Epstein-Barr en los carcinomas de células escamosas de vías aerodigestivas superiores.

OBJECTIVE: Previous studies have investigated the role of viruses in tumor origin of head and neck cancer. Despite this, mechanis of viral carcinogenesis remain unclear. The aim of this study is to determine the prevalence of herpes simplex virus (HSV) and Epstein-Barr virus (EBV) in malignant laryngeal and oropharyngeal lesions. MATERIAL AND METHODS: Fresh frozen specimens of 28 laryngeal and oropharyngeal squamous cell carcinomas were studied. The presence or absence of HSV and EBV was determined with polymerase chain reaction (PCR) assays. RESULTS: None of the samples showed evidence for EBV DNA. One tonsilar carcinoma case (3.5%) was positive for HSV DNA detection. CONCLUSIONS: These results do not support HSV and EBV as etiological factors in head and neck cancer.

Detección del virus herpes simplex y del virus de Epstein-Barr en los carcinomas de células escamosas de vías aerodigestivas superiores / Detection of herpes simplex virus and Epstein-Barr virus in head and neck squamous cell carcinoma

Objetivo: Diversos estudios han investigado el papel de los virus en la carcinogénesis de los tumores de cabeza y cuello. A pesar de esto, el mecanismo de la carcinogénesis viral permanece poco claro. El objetivo de este estudio es determinar la prevalencia del virus herpes simplex (VHS) y del virus de Epstein-Barr (VE-B) en tumores malignos de laringe y orofaringe. Material y método: Se estudian muestras frescas congeladas de 28 pacientes con tumores de laringe y orofaringe. La presencia o ausencia del VHS y VE-B se determinó mediante la reacción en cadena de la polimerasa (PCR). Resultados: En ninguna de las muestras detectamos el ADN del VE-B. En una muestra de carcinoma de amígdala (3,5 por ciento) detectamos el ADN del VHS. Conclusiones: Nuestros resultados no sugieren que el VHS y el VE-B tengan un papel en la etiología de los tumores de cabeza y cuello (AU)

Obesity, diet and restrained eating in a Mediterranean population.

OBJECTIVE: To evaluate links between obesity, gender and restrained eating in a representative sample of adolescents in Catalonia, Spain. DESIGN: Several surveys were conducted in which measurements were taken of a sample of adolescents living in the city of Barcelona. SUBJECTS: 610 subjects (57% girls and 43% boys) with ages ranging between 15-17, from 22 schools in Barcelona. MEASUREMENTS: Weight, height, Body Mass Index (BMI) as measurement of obesity, subscale "Diet' of the Eating Attitudes Test (EAT) as measurement of concern for dieting, and subjects' negative or affirmative responses to the questions as to whether they were following a diet at the time of the study. RESULTS: 15% of the sample was found to be obese (13.5% presented grade I obesity-BMI 25-29.9 kg/m2, 1.3% presented grade II obesity-BMI 30-40 kg/m2, 0.2% presented grade III obesity-BMI > 40 kg/m2). Dieting has a strong influence on normal-weight female adolescent populations in Spain. Such girls are more concerned about dieting and are more likely to follow a diet independent of the extent to which they are overweight. Obese subjects are more likely to show greater concern for their diet and to be on a diet than those of normal-weight. The restrained behaviour observed in obese subjects is not related to the type of restraint evaluated using instruments such as the "Diet' subscale of the EAT. CONCLUSION: Our results show a lower prevalence of obesity in Spain (a European sample) than in the United States. But the prevalence of obesity is not insignificant. It would appear that there is no linear relationship between the degree of excess weight and the restraint boundary. The prevalence of restrained eating behaviour among young adolescent girls in Spain is high. Given the dangers of such attitudes, it is becoming increasingly necessary to develop preventive programmes to combat them.
