Sonographic evolution of the superficial vein thrombosis of the lower extremity.

BACKGROUND: Superficial venous thrombosis (SVT) is a common clinical problem across various treatment settings. SVT shares risk factors with deep venous thrombosis (DVT) and carries a risk of thromboembolic complications, greater than previously expected. Little is known about the pathophysiology, resolution and recurrence of this disease. OBJECTIVES: The objective of the present study was to describe the natural course of SVT, and factors correlated with the progression or resolution of the thrombus. METHODS: We included 218 patients with a recent diagnosis of SVT that were consecutively referred to a thrombosis clinic from the Emergency Department (ED) between January 2016 and April of 2018. RESULTS: The resolution of the thrombus prior to discharge was correlated to gender (female 73.8% vs. male 57.5%, p = 0.015), presence of varicose veins (62.4% vs. 46.4, p = 0.026), absence of family or personal history of thrombosis (98% vs. 91.3%, p = 0.021). The factor most correlated to thrombus resolution prior to discharge was the result of the 2nd ultrasound (improvement 83.9% vs. 16.1%, p < 0.001) immediately after initiation of heparin treatment. In the multivariate analysis, a high thrombus burden in the early follow-up ultrasound was the most significant predictive variable with prior to discharge recanalization (B = 20.9, 95% CI 9.8-44.7; p < 0.001). CONCLUSION: The follow-up of SVT with duplex lower extremity ultrasound allows us to monitor the evolution and early identify residual thrombosis, as a marker of hypercoagulability and recurrence. This study offers new perspectives for future research, necessary to improve the management of this disease, to reduce long-term complications.

Reaffirmation of the importance of follow-up ultrasound studies in patients with high D-dimers and clinical suspicion of vein thrombosis.

BACKGROUND: Venous thromboembolism is a common disease seen in the emergency department and a cause of high morbidity and mortality, constituting a major health problem. OBJECTIVES: To assess the potential benefit of follow-up ultrasound of patients who attended the emergency department with suspected superficial venous thrombosis or deep venous thrombosis and were found to have an initial negative whole-leg (or arm) ultrasound study. METHODS: This retrospective study included patients aged 18 years or older who were consecutively referred to a thrombosis clinic from the emergency department, with abnormal D-dimer test and moderate to high pre-test probability of deep venous thrombosis (Well's score ≥ 1), but a negative whole-leg (or arm) ultrasound. Demographic characteristics, symptom duration, laboratory and ultrasound data were recorded. At one-week follow-up, an experienced physician repeated ultrasound, and recorded the findings. RESULTS: From January 2017 to April 2018, 54 patients were evaluated. The mean age was 66.8 years (SD 15.0) and 63% were women. The average D-dimer was 2159.9 (SD 3772.0) ng/mL. Ultrasound abnormalities were found in 12 patients (22.2%; 95% confidence interval of 12.5 to 36.0%), with 4 patients having proximal deep venous thrombosis, distal deep venous thrombosis in 2 patients and superficial venous thrombosis in 6 patients. We did not find any significant differences in demographic characteristics, venous thromboembolism risk factors or laboratory parameters between patients with negative and positive follow-up ultrasound. CONCLUSIONS: These preliminary findings suggest that a negative whole-leg (or arm) ultrasound in addition to an abnormal D-dimer in moderate to high deep venous thrombosis pretest probability patients, might be an insufficient diagnostic approach to exclude suspected deep venous thrombosis or superficial venous thrombosis. Confirmation of this higher than expected prevalence would support the need to repeat one-week ultrasound control in this population.

Pronóstico de la enfermedad tromboembólica venosa en cirugía ortopédica o pacientes traumatológicos y uso de tromboprofilaxis / Prognosis of venous thromboembolism in orthopaedic surgery or trauma patients and use of thromboprophylaxis

Antecedentes: Hay escasa evidencia sobre el pronóstico de la tromboembolia venosa en pacientes sometidos a cirugía ortopédica y en pacientes que sufren un trauma no quirúrgico. Métodos: Utilizamos la base de datos RIETE (Registro Informatizado de pacientes con Enfermedad TromboEmbólica) para comparar el pronóstico del tromboembolismo venoso y el uso de tromboprofilaxis en pacientes sometidos a diferentes procedimientos ortopédicos y en pacientes con traumatismo que no requiere cirugía. Resultados: Desde marzo de 2001 a marzo de 2015, se inscribieron un total de 61.789 pacientes en RIETE. De estos, 943 (1.52%) desarrollaron tromboembolismo venoso después de artroplastia electiva, 445 (0.72%) después de fractura de cadera, 1.045 (1.69%) después de cirugía ortopédica no mayor y 2,136 (3.46%) después de trauma no quirúrgico. En general, 2.283 pacientes (50%) presentaron inicialmente embolia pulmonar. En los primeros 90 días de tratamiento, 30 pacientes (0.66%, IC 95% 0.45-0.93) murieron por embolia pulmonar. La tasa de embolia pulmonar fatal fue significativamente mayor después de cirugía de fractura de cadera (n = 9 [2.02%]) que después de la artroplastia electiva (n = 5 [0.53%]), cirugía ortopédica no mayor (n = 5 [0.48%]) o traumatismo no quirúrgico (n = 11 [0,48%]). La tromboprofilaxis se utilizó con mayor frecuencia para la fractura de cadera (93%) o la artroplastia electiva (94%) que para la cirugía ortopédica no mayor (71%) o traumatismo no quirúrgico (32%). La hemorragia mayor fue significativamente mayor después de la cirugía de fractura de cadera (4%) que después de artroplastia electiva (1,6%), cirugía ortopédica no mayor (1,5%) o traumatismo no quirúrgico (1,4%). Conclusiones: La tromboprofilaxis se utilizó con menos frecuencia en los procedimientos de menor riesgo a pesar del número absoluto de embolia pulmonar fatal después de cirugía ortopédica no mayor o traumatismo no quirúrgico, excedieron los observados después de procedimientos de alto riesgo

Background: There is scarce evidence about the prognosis of venous thromboembolism in patients undergoing orthopedic surgery and in patients suffering non-surgical trauma. Methods: We used the RIETE database (Registro Informatizado de pacientes con Enfermedad Trombo Embólica) to compare the prognosis of venous thromboembolism and the use of thromboprophylaxis in patients undergoing different orthopedic procedures and in trauma patients not requiring surgery. Results: From March 2001 to March 2015, a total of 61,789 patients were enrolled in RIETE database. Of these, 943 (1.52%) developed venous thromboembolism after elective arthroplasty, 445 (0.72%) after hip fracture, 1,045 (1.69%) after non-major orthopedic surgery and 2,136 (3.46%) after non-surgical trauma. Overall, 2,283 patients (50%) initially presented with pulmonary embolism. Within the first 90 days of therapy, 30 patients (0.66%; 95% CI 0.45-0.93) died from pulmonary embolism. The rate of fatal pulmonary embolism was significantly higher after hip fracture surgery (n = 9 [2.02%]) than after elective arthroplasty (n = 5 [0.53%]), non-major orthopedic surgery (n = 5 [0.48%]) or non surgical trauma (n = 11 [0.48%]). Thromboprophylaxis was more commonly used for hip fracture (93%) or elective arthroplasty (94%) than for non-major orthopedic surgery (71%) or non-surgical trauma (32%). Major bleeding was significantly higher after hip fracture surgery (4%) than that observed after elective arthroplasty (1.6%), non-major orthopedic surgery (1.5%) or non-surgical trauma (1.4%). Conclusions: Thromboprophylaxis was less frequently used in lower risk procedures despite the absolute number of fatal pulmonary embolism after non-major orthopedic surgery or non-surgical trauma, exceeded that observed after high risk procedures

Estudio de cohortes comparando fotovaporización prostática con láser XPS 180 W y HPS 120 W / Cohort study comparing prostate photovaporisation with XPS 180 W and HPS 120 W laser

Introducción y objetivo: La fotovaporización prostática con láser Greenlight, para el tratamiento quirúrgico de la hiperplasia benigna de próstata ha evolucionado rápidamente hasta el nuevo XPS 180 W. Demostramos anteriormente la eficacia y seguridad con el HPS 120 W. El objetivo de este estudio ha sido evaluar los resultados funcionales y de seguridad, con un año de seguimiento, de la fotovaporización mediante el XPS 180 W comparándolo con su predecesor. Material y métodos: Estudio de cohortes sobre una serie de 191 pacientes consecutivos sometidos a fotovaporización entre 01/2008 y 05/2013. Los criterios de inclusión fueron un IPSS >15 tras fracaso médico, un volumen prostático < 80cc y un flujo máximo <15 ml/s. Se evaluaron variables preoperatorias, intraoperatorias (energía empleada, tiempo de láser y tiempo total de la cirugía), complicaciones, horas de sonda, estancia y resultados funcionales (flujo máximo, IPSS, PSA y volumen prostático) a 3, 6 y 12 meses. Se analiza la homogeneidad en las características preoperatorias de los dos grupos mediante técnicas de análisis univariante. Los resultados funcionales postoperatorios se evalúan mediante análisis de la varianza de medidas repetidas con modelos mixtos. Resultados: Se realizaron 109 (57,1%) procedimientos mediante HPS 120 W y 82 (42,9%) mediante XPS. No se encontraron diferencias entre las características preoperatorias. Se observaron diferencias significativas tanto en el tiempo quirúrgico como en el tiempo efectivo de láser a favor del sistema XPS, siendo esta ventaja de un 11% (48 ± 15,7 vs. 53,8 ± 16,2, p < 0,05), y de un 9% (32,8 ± 11,7 vs. 36 ± 11,6, p < 0,05), respectivamente. En el resto de los parámetros analizados no se encontraron diferencias estadísticamente significativas. Conclusión: Las mejorías técnicas del sistema XPS 180 W permiten reducir el tiempo quirúrgico manteniendo el perfil de seguridad y eficacia que ofrecía el sistema HPS 120 W con unos resultados totalmente superponibles con un año de seguimiento

Introduction and objective: Prostate photovaporisation with Greenlight laser for the surgical treatment of benign prostate hyperplasia has rapidly evolve to the new XPS 180 W. We have previously demonstrated the safety and efficacy of the HPS 120 W. The aim of this study was to assess the functional and safety results, with a year of follow-up, of photovaporisation using the XPS 180 W laser compared with its predecessor. Material and methods: A cohort study was conducted with a series of 191 consecutive patients who underwent photovaporisation between 1/2008 and 5/2013. The inclusion criteria were an international prostate symptom score (IPSS) >15 after medical failure, a prostate volume < 80 cc and a maximum flow <15 mL/s. We assessed preoperative and intraoperative variables (energy used, laser time and total surgical time), complications, catheter hours, length of stay and functional results (maximum flow, IPSS, prostate-specific antigen and prostate volume) at 3, 6 and 12 months. We analysed the homogeneity in preoperative characteristics of the 2 groups through univariate analysis techniques. The postoperative functional results were assessed through an analysis of variance of repeated measures with mixed models. Results: A total of 109 (57.1%) procedures were performed using HPS 120 W, and 82 (42.9%) were performed using XPS. There were no differences between the preoperative characteristics. We observed significant differences both in the surgical time and effective laser time in favour of the XPS system. This advantage was 11% (48 ± 15.7 vs. 53.8 ± 16.2, p< .05) and 9% (32.8 ± 11.7 vs. 36 ± 11.6, p< .05), respectively. There were no statistically significant differences in the rest of the analysed parameters. Conclusion: The technical improvements in the XPS 180 W system help reduce surgical time, maintaining the safety and efficacy profile offered by the HPS 120 W system, with completely superimposable results at 1 year of follow-up

Los estudios prospectivos de pacientes consecutivos con enfermedad tromboembólica venosa no identifican a todos los pacientes en riesgo. Análisis multicéntrico ambispectivo del grupo Contaminatep / Prospective studies of consecutive patients with venous thromboembolic disease fail to identify all patients at risk. Multicenter, ambispective analysis of the Contaminatep Group

INTRODUCCIÓN: nuestro grupo ha comenzado un trabajo para estudiar la relación entre la incidencia de TEP y la contaminación ambiental. Para establecer una relación, es una condición metodológica fundamental contar con todos los casos incidentes en un periodo de tiempo. Por este motivo diseñamos este estudio, para valorar la eficacia de recogida de pacientes consecutivos con TEP. MATERIAL Y MÉTODOS: realizamos un estudio ambispectivo, multicéntrico, de un año de duración. En una primera fase se incluyeron prospectivamente todos los casos que ingresaron con diagnóstico de TEP y posteriormente, de forma retrospectiva, realizamos una revisión de los registros hospitalarios de cada uno de los centros participantes. Así, calculamos la eficacia dividiendo el número de casos incidentes en fase prospectiva por el número total de casos reclutados en ambas fases. RESULTADOS: desde febrero 2012 a febrero 2013 se reclutaron 839 pacientes (440 prospectivamente). El reclutamiento prospectivo presentó una eficacia de detección de TEP del 52,4%, mostrando variabilidad según el centro (29,3 - 100%). Cuando analizamos sólo a los pacientes con TEP agudo sintomático idiopático, la eficacia fue del 59,8 %, con variabilidad según centro (31,7 - 100%). La eficacia de reclutamiento de pacientes con TEP secundario o idiopático fue de 42,1% vs. 59,8%, respectivamente (p < 0,001). CONCLUSIONES: en los estudios prospectivos, el porcentaje de pacientes no diagnosticados no es desdeñable. Los resultados de este estudio nos deben hacer pensar en estrategias adicionales para reclutar pacientes consecutivos de forma correcta, principalmente en aquellos estudios donde la pérdida de pacientes supondría un sesgo a la hora de emitir conclusiones

INTRODUCTION: we are studying the relationship between the incidence of pulmonary embolism (PE) and air pollution, and all symptomatic PE were needed over a period of time to establish a relationship. For this reason we designed this study, to assess the efficacy of collection consecutive patients with PE. METHODS: ambispective, multicenter study, from February 2012 to February 2013. In the first phase, we included prospectively all cases admitted at the hospital with PE diagnosis, and in the second phase, we reviewed retrospectively, hospital records from each participating center. So, we calculate the efficacy by dividing the number of incident cases in prospective phase by the total number of cases recruited in both phases. RESULTS: during one year, 839 patients were recruited (440 prospectively). The prospective recruitment presented a PE efficacy detection of 52.4%, showing variability according to the center between 29.3 to 100%. When we analyzed only patients with idiopathic symptomatic PE, efficacy was 59.8%, with variability according to the center between 31.7 to 100%. The recruitment efficacy of patients with secondary or idiopathic PE was 42.1% vs. 59.8%, respectively (p < 0.001). CONCLUSIONS: A wide percentage of patients can pass up from prospectives studies. The results of this study try to make us think, that we need more strategies to get a good recruit of consecutive patients, especially in those studies where is essential collect all patients

Cambios en el grado de Gleason en las biopsias de seguimiento de pacientes con cáncer de próstata en programa de vigilancia activa / Changes in Gleason score grading on serial follow-up biopsies in prostate cancer patients undergoing active surveillance

Introducción: Las series publicadas sobre vigilancia activa (VA) son cada vez más numerosas. La variación del Gleason a lo largo de las biopsias de seguimiento no se detalla en muchas de estas publicaciones. Objetivos: Evaluar los cambios en el grado de Gleason de las biopsias de seguimiento en pacientes con cáncer de próstata de bajo riesgo en programa de VA. Material y métodos: Análisis de pacientes diagnosticados entre 2004 y 2013. Criterios de inclusión: PSA ≤ 10 ng/ml, Gleason ≤ 6, T1c/T2a, ≤ 2 cilindros positivos, afectación máxima del cilindro de un 50%. Se analizaron los datos anatomopatológicos de cada una de las biopsias. Resultados: Serie de 175 pacientes incluidos en vigilancia activa con media de seguimiento de 3,96 años (DE: 2,4). Las tasas de Gleason ≥ 7 en las biopsias de seguimiento fueron: 5,72% en la primera biopsia, 7,39% y 7,41% en las biopsias sucesivas. Por el contrario, no se evidenció afectación tumoral en el 42,03% de los casos en la primera biopsia, 40,74% y 51,85% en segunda y terceras biopsias respectivamente. La mediana de permanencia en el programa en los pacientes con la primera biopsia positiva fue 90,99 meses (IC 95%: 53,53-128,46) vs 96,66 meses (IC 95%: 63,19-130,13) en aquellos sin evidencia de malignidad. Conclusiones: En nuestra serie las 3 primeras biopsias se mantienen con unas proporciones estables en cuanto a positividad de la biopsia, grado de Gleason o indicación de tratamiento activo. Los pacientes que en la primera biopsia de seguimiento no tienen evidencia de malignidad tienen menor probabilidad de necesitar tratamiento activo que el resto de la serie

Introduction: Active surveillance for prostate cancer has grown systematically in the recent years with more robust mid-term outcomes. However, changes in Gleason score during serial biopsies are not detailed in many of these reports. Objectives: To evaluate changes in Gleason score on follow-up biopsies in low-risk prostate cancer in patients undergoing AS program in our center. Material and methods: Series of patients diagnosed of prostate cancer between 2004 and 2013 have been analyzed. The inclusion criteria were: PSA ≤ 10 ng/ml + Gleason ≤ 6 + T1c/T2a + ≤ 2 positive cores, and no more than 50% of affected core. The pathology of each of the biopsies was analyzed. Results: We studied a series of 175 patients undergoing AS. Mean follow-up was 3.96 years (SD 2.4). Follow-up biopsies with Gleason scores ≥ 7 were: 5.72% in the first biopsy, 7.39% and 7.41% in subsequent biopsies. By contrast, in 42.03% of cases did not show evident tumor involvement in the first biopsy, 40.74% and 51.85% in the second and third biopsies respectively. Median stay in the AS program was: 90.99 months (95% CI: 53.53-128.46) in patients with first positive biopsy vs. 96.66 months (95% CI: 63.19-130.13) in those without evidence of tumor. Conclusions: In our series the pathological data of the first 3 biopsies remain stable in terms of the positive biopsy rate, Gleason score, or indication of active treatment proportions. Those patients who do not show evidence of malignancy in the first follow-up biopsy are less likely to need active treatment than the other patients in the series

Estudio multicéntrico de costes de 2 técnicas quirúrgicas: láser GreenLight XPS 180 W vs resección transuretral de la próstata / Multicenter Study on Costs Associated With Two Surgical Procedures: GreenLight XPS 180 W Versus the Gold Standard Transurethral Resection of the Prostate

Objetivo: Analizar los costes asociados al tratamiento quirúrgico de la sintomatología del tracto urinario inferior secundaria a hiperplasia benigna de próstata mediante el láser GreenLigh XPS 180 W respecto a la técnica quirúrgica endoscópica de referencia, resección transuretral de la próstata. Métodos: Se realizó un estudio retrospectivo y multicéntrico de costes desde la perspectiva del Sistema Nacional de Salud y en un horizonte temporal de 3 meses, desagregándolos en fases temporales: prequirúrgica, quirúrgica y posquirúrgica. Los datos fueron extraídos de las historias de los pacientes intervenidos secuencialmente, con IPSS = 15, Qmax = 15 ml/seg y volumen prostático de 40-80 ml, incorporando solo costes sanitarios directos (euros de 2013) asociados a la intervención y al manejo de complicaciones. Resultados: Entre julio y octubre de 2012 se intervinieron de forma secuencial 39 pacientes con láser GL XPS y 40 con RTUP. El resultado clínico fue equivalente (94,9 y 92,5%, respectivamente) no mostrando diferencias estadísticamente significativas (p = 0,67). El coste medio total por paciente se redujo en 121 Euros en el grupo láser GL XPS respecto de RTUP; en la fase quirúrgica el coste fue superior con láser GL XPS (diferencia: 1.209 Euros; p < 0,001) mientras que fue inferior en la fase posquirúrgica (diferencia: -1.351 Euros, p < 0,001). Conclusiones: La intervención de los pacientes con STUI secundario a HBP mediante la nueva tecnología láser GL XPS se asocia a una reducción de costes respecto de la RTUP, debida a una menor duración de la estancia hospitalaria, la cual compensa el coste imputado a dicha tecnología

Objective: To analyze the costs associated with two surgical procedures for lower urinary tract symptoms secondary to benign prostatic hyperplasia: GreenLight XPS 180 W versus the gold standard transurethral resection of the prostate. Methods: A multicenter, retrospective cost study was carried out from the National Health Service perspective, over a 3-month time period. Costs were broken down into pre-surgical, surgical and post-surgical phases. Data were extracted from records of patients operated sequentially, with IPSS = 15, Qmax = 15 mL/seg and a prostate volume of 40–80 mL, adding only direct healthcare costs (Euros, 2013) associated with the procedure and management of complications. Results: A total of 79 patients sequentially underwent GL XPS (n: 39) or TURP (n: 40) between July and October 2013. Clinical outcomes were similar (94.9% and 92.5%, GL XPS and TURP, respectively) without significant differences (p = 0.67). The average direct cost per patient was reduced by 114Euros in GL XPS versus TURP patients; the cost was higher in the surgical phase with GL XPS (difference: 1209Euros; p < 0.001) but was lower in the post-surgical phase (difference: Euros − 1351; p < 0.001). Conclusions: The GreenLight XPS 180-W laser system is associated with a reduction in costs with respect to transurethral resection of prostate in the surgical treatment of LUTS secondary to PBH. This reduction is due to a shorter inpatient length of stay that offsets the cost of the new technology

Historia natural de la enfermedad tromboembólica venosa en el área mediterránea. Una revisión sistemática / Natural history of venous thromboembolism in patients from the Mediterranean region. A systematic review

Antecedentes: El pronóstico de las enfermedades cardiovasculares es mejor en los países mediterráneos que en otras partes del mundo. Se desconoce si estas diferencias también acontecen en la enfermedad tromboembólica venosa (ETV) Métodos: En las bases de datos Medline y EMBASE se revisaron los ensayos clínicos y estudios de cohortes de pacientes con ETV que habían recibido tratamiento anticoagulante durante 3 meses. Dos revisores extrajeron independientemente los datos de forma reglada. Se seleccionaron 24 estudios con un total de 7.225 pacientes incluidos (2.414 del área mediterránea y 4.811 de otras regiones). Resultados: Entre los pacientes del área mediterránea predominaban las mujeres, tenían mayor edad, y la ETV idiopática fue menos frecuente que en otras regiones del mundo. Comparados con otros países, los pacientes del área mediterránea presentaron más recidivas de trombosis venosa profunda (4,35% frente a 2,68%; odds ratio [OR]: 1,65; intervalo de confianza al 95% [IC95%]: 1,27-2,15), recidivas mortales de ETV (0,75% frente a 0,35%; OR: 2,11; IC95%: 1,09-4,12) y sangrado mortal (0,25% frente a 0,06%; OR: 3,99; IC95%: 1-16). En el área mediterránea el porcentaje de recidivas de ETV mortal fue del 12,8%, IC95%: 7,99-19,1 frente al 8,41%, IC95%: 5,15-12,9 en otras zonas del mundo. El porcentaje de hemorragias mortales fue del 11,3%, IC95%: 4,72-22,1 frente al 3,22%, IC95%: 0,83-8,53 en otras zonas geográficas. Conclusiones: Los pacientes con ETV del área mediterránea tienen una mayor mortalidad durante los 3 primeros meses de tratamiento imputable a una mayor incidencia de ETV recidivante y de hemorragias graves (AU)

Background: Patients with cardiovascular diseases living in the Mediterranean area have a better outcome than those in other parts of the world, but it is not known whether these differences also occur with venous thromboembolism (VTE). Methods: We searched the Medline and EMBASE databases to identify clinical trials and cohort studies of patients with VTE who had been treated with anticoagulant therapy for 3 months. Two reviewers independently extracted the data in a standardized manner. A total of 24 studies that included 7,225 patients (2,414 from the Mediterranean region and 4,811 from other regions) were analyzed. Results: The patients from the Mediterranean area were predominately women and older, and the idiopathic VTE was less frequent than in other regions. Compared with patients from other regions, patients from the Mediterranean region had an increased rate of recurrent deep vein thrombosis (4.35% vs. 2.68%; odds ratio [OR], 1.65; 95% confidence interval [95% CI] 1.27-2.15), fatal recurrent VTE (0.75% vs. 0.35%; OR, 2.11; 95% CI 1.09-4.12) and fatal bleeding (0.25% vs. 0.06%; odds ratio: 3.99; 95% CI 1.00-16.0). The case-fatality rate (CFR) for recurrent VTE was 12.8% (95% CI 7.99-19.1) in the Mediterranean region and 8.41% (5.15-12.9) in other areas. The CFR for major bleeding was 11.3% (95% CI 4.72-22.1) and 3.22% (95% CI 0.83-8.53), respectively. Conclusions: Compared to other regions, patients with VTE from the Mediterranean region have greater mortality during the first 3 months of treatment due to a greater incidence of recurrent VTE and severe hemorrhaging (AU)

Natural history of venous thromboembolism in patients from the Mediterranean region. A systematic review.

BACKGROUND: Patients with cardiovascular diseases living in the Mediterranean area have a better outcome than those in other parts of the world, but it is not known whether these differences also occur with venous thromboembolism (VTE). METHODS: We searched the Medline and EMBASE databases to identify clinical trials and cohort studies of patients with VTE who had been treated with anticoagulant therapy for 3 months. Two reviewers independently extracted the data in a standardized manner. A total of 24 studies that included 7,225 patients (2,414 from the Mediterranean region and 4,811 from other regions) were analyzed. RESULTS: The patients from the Mediterranean area were predominately women and older, and the idiopathic VTE was less frequent than in other regions. Compared with patients from other regions, patients from the Mediterranean region had an increased rate of recurrent deep vein thrombosis (4.35% vs. 2.68%; odds ratio [OR], 1.65; 95% confidence interval [95% CI] 1.27-2.15), fatal recurrent VTE (0.75% vs. 0.35%; OR, 2.11; 95% CI 1.09-4.12) and fatal bleeding (0.25% vs. 0.06%; odds ratio: 3.99; 95% CI 1.00-16.0). The case-fatality rate (CFR) for recurrent VTE was 12.8% (95% CI 7.99-19.1) in the Mediterranean region and 8.41% (5.15-12.9) in other areas. The CFR for major bleeding was 11.3% (95% CI 4.72-22.1) and 3.22% (95% CI 0.83-8.53), respectively. CONCLUSIONS: Compared to other regions, patients with VTE from the Mediterranean region have greater mortality during the first 3 months of treatment due to a greater incidence of recurrent VTE and severe hemorrhaging.

Multicenter study on costs associated with two surgical procedures: GreenLight XPS 180 W versus the gold standard transurethral resection of the prostate.

OBJECTIVE: To analyze the costs associated with two surgical procedures for lower urinary tract symptoms secondary to benign prostatic hyperplasia: GreenLight XPS 180¦W versus the gold standard transurethral resection of the prostate. METHODS: A multicenter, retrospective cost study was carried out from the National Health Service perspective, over a 3-month time period. Costs were broken down into pre-surgical, surgical and post-surgical phases. Data were extracted from records of patients operated sequentially, with IPSS=15, Qmax=15 mL/seg and a prostate volume of 40-80mL, adding only direct healthcare costs (€, 2013) associated with the procedure and management of complications. RESULTS: A total of 79 patients sequentially underwent GL XPS (n: 39) or TURP (n: 40) between July and October, 2013. Clinical outcomes were similar (94.9% and 92.5%, GL XPS and TURP, respectively) without significant differences (P=.67). The average direct cost per patient was reduced by €114 in GL XPS versus TURP patients; the cost was higher in the surgical phase with GL XPS (difference: €1,209; P<.001) but was lower in the post-surgical phase (difference: €-1,351; P<.001). CONCLUSIONS: The GreenLight XPS 180-W laser system is associated with a reduction in costs with respect to transurethral resection of prostate in the surgical treatment of LUTS secondary to PBH. This reduction is due to a shorter inpatient length of stay that offsets the cost of the new technology.

INTRODUCTION: The aim of this study is to establish the risk of thromboembolic events and evaluation of the use of venous thromboembolism prophylaxis in hospitalized medical patients and after discharge, and their concordance with protocols used in our hospital. MATERIAL AND METHODS: We performed a cross-sectional with prospective follow-up until hospital discharge. It included all medical patients in Internal Medicine, Pneumology and Oncology Departments. The patient's thromboembolic risk and type of thromboembolism prophylaxis indication during hospitalization and after discharge were determined. RESULTS: A total of 116 patients (52 in Internal Medicine Department, 35 in Pneumology Department and 29 in Oncology Department), with a mean age of 67 +/- 17 years (35 females; 81 males) were included. During hospitalization, 62.9% of the patients had a high risk of thromboembolic events, 3.4% a moderate risk, 23.3% low risk, and 10.3% had no risk. After discharge, these proportions were 35.6%, 3.8%, 24% and 34.6%, respectively. A total of 49.1% of the patients had an adequate indication of venous thromboembolism prophylaxis during the hospitalization and after discharge.

The influence of extreme body weight on clinical outcome of patients with venous thromboembolism: findings from a prospective registry (RIETE).

BACKGROUND: Data evaluating the safety of using weight-based dosing of low-molecular-weight heparin (LMWH) in either underweight or obese patients with venous thromboembolism (VTE) are limited. Thus, recommendations based on evidence from clinical trials might not be suitable for patients with extreme body weight. PATIENTS AND METHODS: Patients with objectively confirmed, symptomatic acute VTE are consecutively enrolled into the Registro Informatizado de la Enfermedad TromboEmbólica (RIETE) registry. For this analysis, data from patients in the following ranges of body weight were examined: <50, 50-100, and >100 kg. Patient characteristics, underlying conditions, treatment schedules and clinical outcomes during the first 15 days of treatment were compared. RESULTS: As of August 2004, 8845 patients with acute VTE were enrolled from 94 participating centers. Of these, 169 (1.9%) weighed <50 kg, 8382 (95%) weighed 50-100 kg and 294 (3.3%) weighed >100 kg. Patients weighing <50 kg were more commonly females, were taking non-steriodal antiinflammatory drugs (NSAIDs), and had severe underlying diseases more often than patients weighing 50-100 kg. Their incidence of overall bleeding complications was significantly higher than in patients weighing 50-100 kg (odds ratio 2.2; 95% CI: 1.2-4.0). Patients weighing >100 kg were younger, most commonly males, and had cancer less often than those weighing 50-100 kg. Incidences of recurrent VTE, fatal pulmonary embolism or major bleeding complications were similar in both groups. CONCLUSIONS: Patients with VTE weighing <50 kg have a significantly higher rate of bleeding complications. The clinical outcome of patients weighing over 100 kg was not significantly different from that in patients weighing 50-100 kg.

Abnormalities on 1q and 7q are associated with poor outcome in sporadic Burkitt's lymphoma. A cytogenetic and comparative genomic hybridization study.

Comparative genomic hybridization (CGH) studies have demonstrated a high incidence of chromosomal imbalances in non-Hodgkin's lymphoma. However, the information on the genomic imbalances in Burkitt's Lymphoma (BL) is scanty. Conventional cytogenetics was performed in 34 cases, and long-distance PCR for t(8;14) was performed in 18 cases. A total of 170 changes were present with a median of four changes per case (range 1-22). Gains of chromosomal material (143) were more frequent than amplifications (5) or losses (22). The most frequent aberrations were gains on chromosomes 12q (26%), Xq (22%), 22q (20%), 20q (17%) and 9q (15%). Losses predominantly involved chromosomes 13q (17%) and 4q (9%). High-level amplifications were present in the regions 1q23-31 (three cases), 6p12-p25 and 8p22-p23. Upon comparing BL vs Burkitt's cell leukemia (BCL), the latter had more changes (mean 4.3 +/- 2.2) than BL (mean 2.7 +/- 3.2). In addition, BCL cases showed more frequently gains on 8q, 9q, 14q, 20q, and 20q, 9q, 8q and 14q, as well as losses on 13q and 4q. Concerning outcome, the presence of abnormalities on 1q (ascertained either by cytogenetics or by CGH), and imbalances on 7q (P=0.01) were associated with a short survival.
