Ventilación mecánica en España, 1998-2016: cambios en la desconexión de la ventilación mecánica / Mechanical ventilation in Spain, 1998-2016: changes in the disconnection of mechanical ventilation

Objetivo Evaluar los cambios en la desconexión de la ventilación mecánica en España desde 1998 hasta 2016. Diseño Análisis post-hoc de 4 estudios de cohorte. Ámbito Un total de 138 UCI. Enfermos Un total de 2.141 enfermos extubados de forma programada. Intervenciones Ninguna. Variables de interés principales Demográficas, motivo de ventilación mecánica, complicaciones, métodos para la desconexión, fracaso del primer intento de desconexión, duración de la desconexión, reintubación, traqueotomía post-reintubación, estancia y mortalidad en la UCI. Resultados Se observa un aumento significativo (p<0,001) en la presión de soporte como técnica de desconexión. Ha aumentado, a lo largo del tiempo, la probabilidad ajustada de utilizar la presión de soporte progresivamente decreciente frente a una prueba de ventilación espontánea, tanto para el primer intento de desconexión (referencia estudio de 1998: odds ratio 0,99 en 2004, 0,57 en 2010 y 2,43 en 2016) como para la desconexión difícil/prolongada (referencia estudio de 1998: odds ratio 2,29 en 2004, 1,23 en 2010 y 2,54 en 2016). La proporción de extubación tras el primer intento de desconexión ha aumentado con el tiempo. Hay una disminución del tiempo dedicado a la desconexión (desde un 45% en 1998 hasta un 36% en 2016). Sin embargo, no ha disminuido la duración en la desconexión difícil/prolongada (mediana 3 días en todos los estudios, p=0,435). Conclusiones Ha habido cambios significativos en el modo de desconexión de la ventilación mecánica, con un aumento progresivo del uso de la presión de soporte. Se han observado mínimos cambios en los desenlaces (AU)

Purpose To evaluate changes in the disconnection of mechanical ventilation in Spain from 1998 to 2016. Design Post-hoc analysis of four cohort studies. Ambit 138 Spanish ICUs. Patients 2141 patients scheduled extubated. Interventions None. Variables of interest Demographics, reason for mechanical ventilation, complications, methods for disconnection, failure on the first attempt at disconnection, duration of weaning, reintubation, post-reintubation tracheotomy, ICU stay and mortality. Results There was a significant increase (p<0.001) in the use of gradual reduction of support pressure. The adjusted probability of using the gradual reduction in pressure support versus a spontaneous breathing trial has increased over time, both for the first attempt at disconnection (taking the 1998 study as a reference: odds ratio 0.99 in 2004, 0.57 in 2010 and 2.43 in 2016) and for difficult/prolonged disconnection (taking the 1998 study as a reference: odds ratio 2.29 in 2004, 1.23 in 2010 and 2.54 in 2016). The proportion of patients extubated after the first attempt at disconnection has increased over time. There is a decrease in the ventilation time dedicated to weaning (from 45% in 1998 to 36% in 2016). However, the duration in difficult/prolonged weaning has not decreased (median 3 days in all studies, p=0.435). Conclusions There have been significant changes in the mode of disconnection of mechanical ventilation, with a progressive increase in the use of gradual reduction of pressure support. No relevant changes in outcomes have been observed (AU)

Survival outcomes and prognostic factors of endometrial stromal sarcoma and undifferentiated uterine sarcoma

Purpose To review the diagnostic and therapeutic procedures of patients diagnosed with Endometrial Stromal Sarcoma (ESS) and Undifferentiated Uterine Sarcoma (USS) at our institution and investigate their clinical outcomes and factors affecting prognosis. Methods We retrospectively collected demographic data, preoperative diagnostic methods and therapeutic management of patients treated for ESS and UUS between January 1995 and December 2019 at Vall d’Hebron Barcelona Hospital Campus, Spain. Overall survival and disease-free survival were calculated. Cox proportional-hazards regression models were calculated. Results Sixty-three patients were included in the study, of which 51(81%) had a diagnosis of ESS and 12(19%) of UUS. Twenty patients (31.7%) were diagnosed after a previous non-oncologic surgery, and 12 of them (60%) suffered from tumor disruption. Cytoreductive procedures were needed in 29 patients (46%), and optimal cytoreduction was achieved in 80.9% of the patients. The median follow-up was 7.6 years (IQR = 0.99–14.31). Five-year overall survival was 57.6% (44.2–68.8) and was significantly better for low-grade ESS (LG-ESS) patients (p < 0.01). Five-year disease-free survival was 57.1% (42.8–69.1) and was also significantly higher in LG-ESS cohort (p = 0.03). After multivariate analysis histological type, age, FIGO stage, optimal surgery and mitotic index were found significantly correlated with survival. For high-grade EES (HG-ESS) and USS patients adjuvant radiotherapy also correlated with improved survival. Conclusion Overall survival and disease-free survival are significantly better in patients with LG-ESS cohort. HG-ESS and UUS show similar survival outcomes. Age, FIGO stage, optimal surgery and histological type were significantly correlated with survival in the global cohort, whilst adjuvant radiotherapy correlated with improved survival in HG-ESS and UUS patients (AU)

Ventilación mecánica en España, 1998-2016: epidemiología y desenlaces / Mechanical ventilation in Spain, 1998-2016: Epidemiology and outcomes

OBJETIVO: Evaluar cambios en la epidemiología de la ventilación mecánica en España desde 1998 hasta 2016. DISEÑO: Análisis post-hoc de 4 estudios de cohortes. ÁMBITO: Un total de 138 UCI españolas. PACIENTES: Un total de 4.293 enfermos con ventilación mecánica invasiva más de 12h o no invasiva más de 1h. INTERVENCIONES: Ninguna. VARIABLES DE INTERÉS PRINCIPALES: Demográficas, motivo de ventilación mecánica, relacionadas con el soporte ventilatorio (modo de ventilación, volumen tidal, PEEP, presiones en vía aérea), complicaciones, duración de la ventilación mecánica, estancia y mortalidad en la UCI. RESULTADOS: Se observa aumento en la gravedad (SAPSII: 43 puntos en 1998 frente a 47 puntos en 2016), cambios en el motivo de la ventilación mecánica (disminución de la enfermedad pulmonar obstructiva crónica e insuficiencia respiratoria secundaria a traumatismo y aumento de la patología neurológica y tras parada cardiaca). Aumento en la ventilación no invasiva como primer modo de soporte ventilatorio (p < 0,001). El modo más utilizado es la ventilación controlada por volumen con un aumento de la presión de soporte y de la ventilación controlada por volumen regulada por presión. Disminuyó el volumen tidal (9ml/kg de peso estimado en 1998 y 6,6ml/kg en 2016, p < 0,001) y aumentó la PEEP (3cmH2O en 1998 y 6cmH2O en 2016, p < 0,001). La mortalidad disminuye (34% en 1998 y 27% en 2016; p < 0,001) sin variabilidad geográfica (MOR 1,43; p = 0,258). CONCLUSIONES: Se observa una disminución en la mortalidad de los enfermos ventilados en UCI españolas. Esta disminución podría estar relacionada con cambios para minimizar el daño inducido por el ventilador

PURPOSE: To evaluate changes in the epidemiology of mechanical ventilation in Spain from 1998 to 2016. DESIGN: A post hoc analysis of four cohort studies was carried out. SETTING: A total of 138 Spanish ICUs. PATIENTS: A sample of 4293 patients requiring invasive mechanical ventilation for more than 12h or noninvasive ventilation for more than 1h. INTERVENTIONS: None. VARIABLES OF INTEREST: Demographic variables, reason for mechanical ventilation, variables related to ventilatory support (ventilation mode, tidal volume, PEEP, airway pressures), complications during mechanical ventilation, duration of mechanical ventilation, ICU stay and ICU mortality. RESULTS: There was an increase in severity (SAPSII: 43 points in 1998 vs. 47 points in 2016), changes in the reason for mechanical ventilation (decrease in chronic obstructive pulmonary disease and acute respiratory failure secondary to trauma, and increase in neurological disease and post-cardiac arrest). There was an increase in noninvasive mechanical ventilation as the first mode of ventilatory support (p < 0.001). Volume control ventilation was the most commonly used mode, with increased support pressure and pressure-regulated volume-controlled ventilation. A decrease in tidal volume was observed (9ml/kg actual b.w. in 1998 and 6.6ml/kg in 2016; p < 0.001) as well as an increase in PEEP (3cmH2O in 1998 and 6cmH2O in 2016; p < 0.001). In-ICU mortality decreased (34% in 1998 and 27% in 2016; p < 0.001), without geographical variability (median OR 1.43; p = 0.258). CONCLUSIONS: A significant decrease in mortality was observed in patients ventilated in Spanish ICUs. These changes in mortality could be related to modifications in ventilation strategy to minimize ventilator-induced lung injury

Análisis de resultados en cirugía de revisión de márgenes de sarcomas de partes blandas / Analysis of results of soft tissue sarcoma margins revision surgery

Introducción. En ocasiones, a los hospitales especializados en sarcomas son derivados pacientes desde otros centros donde se les ha realizado una cirugía no planeada de resección de sarcoma de partes blandas. Material y métodos. Entre noviembre del 2001 y julio del 2013, 35 pacientes de este tipo fueron derivados a nuestro centro. Resultados. El 29% de los pacientes había sido intervenido sin pruebas complementarias previas. En el 76% el diagnóstico de sarcoma se descubrió en el estudio histológico postoperatorio. El sarcoma sinovial fue el más común encontrado, afectando el 38% de los pacientes. A todos ellos se les realizó cirugía de revisión de márgenes y en el 86% se realizó terapia adyuvante. El 69% de los pacientes tenían enfermedad residual hallada en la anatomía patológica. Al final del seguimiento, el 12% había presentado recidiva local, otro 12% diseminación a distancia y el 3% había fallecido. Conclusión. Dados los resultados, concluimos que cualquier tumoración de partes blandas de la que se sospeche malignidad ha de ser resecada en un centro de referencia, y si se ha producido una resección no planeada en otro centro tiene que ser derivado inmediatamente para la realización reglada de un estudio de imagen, cirugía de revisión y, si precisa, tratamiento adyuvante (AU)

Introduction. Patients from other centres where they have had an unplanned surgical resection of a soft tissue sarcoma are often referred to hospitals specialised in sarcomas. Material and methods. A study was conducted on 35 patients who required this type of surgery were referred to our center between November 2001 and July 2013. Results. Surgery had been performed on 29% of the patients without any complementary tests being done. In 75% of cases, the sarcoma diagnosis was discovered in the post-surgical histological study. Synovial sarcoma was the most common, affecting 38% of the patients. A surgical revision of the margins was performed on all of them, and adjuvant treatment was performed on 86% of them. The histopathology study found that 69% of the patients had residual disease. At the end of follow-up, 12% had a local recurrence, another 12% distant metastases, and 3% had died. Conclusion. Given the results, it is concluded that any tumour of the soft tissues in which malignancy is suspected has to be resected in a reference centre. If an unplanned esection was performed in another centre, it should be referred immediately in order to perform an imaging study, revision surgery, and if required, adjuvant treatment (AU)

Colestasis y listeriosis en el tercer trimestre de la gestación / Cholestasis and listeriosis in the third trimester of pregnancy

La listeriosis es una infección producida por Listeria monocytogenes. Poco frecuente, afecta a personas en edades extremas de la vida, gestantes, inmunodeprimidos y, ocasionalmente, a individuos sanos. Su incidencia ha aumentado en los últimos años y presenta cierta tendencia a la estacionalidad, aumentando en verano. Puede aparecer de forma esporádica o a brotes. En gestantes, la infección se produce más frecuentemente en el tercer trimestre y la clínica suele ser leve. Sin embargo, la infección sobre el feto es severa, pudiendo producir abortos, muertes fetales, corioamnionitis y partos pretérmino con recién nacidos infectados, manifestándose en forma de granulomatosis infantiséptica con abscesos y granulomas diseminados o, tardíamente, como meningitis y sepsis. La colestasis intrahepática es una forma reversible de colestasis, de causa desconocida y específica de la gestación, siendo mas frecuente en multíparas, en el tercer trimestre y rara antes de la semana 26ª. Desaparece tras el parto y constituye la segunda causa de ictericia en la gestación, por detrás de la hepatitis. El diagnóstico de colestasis es fundamentalmente clínico. Se manifiesta por prurito palmo plantar pero también puede cursar con náuseas, vómitos y molestias abdominales localizadas en hipocondrio derecho. Dado que la listeriosis y colecistitis pueden compartir sintomatología, habrá que tener en cuenta la posibilidad de listeriosis para poner en marcha los mecanismos de confirmación diagnóstica (cultivo de fluidos o tejidos estériles: sangre, LCR neonatal, líquido amniótico o placenta)y el tratamiento específico precozmente. Se presenta un caso de colestasis y listeriosis en el tercer trimestre con buen resultado maternofetal (AU)

Listeriosis is an infection produced by Listeria monocytogenes. It is infrequent and affects people at extreme ages, pregnant women, immune compromised people and, occasionally, healthy people. Its incidence has increased in recent years and shows a certain tendency to seasonality, increasing in summer. It can appear sporadically or as outbreaks.In pregnant women the infection is most frequently produced in the third trimester and the symptoms are usually light. Nonetheless, the infection of the fetus is severe, and can produce miscarriages, fetal deaths, corioamnionitis and premature births with the newborn infected, manifested in the form of granulomatosis infantiseptica with abscesses and scattered granulomas or at a later stage , as meningitis or sepsis. Intrahepatic cholestasis is a reversible form of cholestasis, its cause is unknown, it is specific to pregnancy and is more frequent in multiparous women, in the third trimester and rarely before the 26th week. It disappears following childbirth and is the second cause of jaundice in pregnancy, after hepatitis. The diagnosis of cholestasis is basically clinical. It appears as palmoplantar pruritus but can also produce nausea, vomiting and abdominal discomfort localized in the right hypochondrium. Given that listeriosis and cholestasis can have a shared symptomology, the possibility of listeriosis must be borne in mind in order for early implementation of the mechanisms of diagnostic confirmation (cultivation of sterile fluids or tissues: blood, neonatal CSF, amniotic liquid or placenta) and specific treatment. We present a case of cholestasis and listeriosis in the third trimester with a good maternofetal result (AU)

Sentinel lymph node identification in a primary ductal carcinoma arising in the vulva.

Primary or metastatic breast-like carcinoma of the vulva is a rare event. Because of the similarity with breast ductal carcinoma, we think that the same principles used for treatment of orthotopic breast cancer can be applied, as well as the use of sentinel lymph node technique, which is widely accepted in the management of early-stage breast cancer. We report a 49-old-year postmenopausal woman who was referred to our institution after small biopsy of a 3.5- x 3-cm right vulvar tumor. Histopathologically, infiltration of the vulvar dermis by a ductal carcinoma of mammary gland type was reported. At operation, the sentinel node technique revealed two sentinel nodes in the right inguinal area. Although these nodes proved negative for malignancy, the patient underwent wide local excision of tumor and complete ipsilateral inguinofemoral lymphadenectomy. The remaining excised nodes were negative. Surgical specimen proved estrogen- and progesterone-positive receptors, the reason for which the patient received tamoxifen adjuvant therapy. This report represents the first case in the world literature of primary breast carcinoma arising in the vulva in which sentinel lymph node identification has been possible. Because of the rarity of this condition, the pathologic similarity of this tumor along with currently accepted guidelines for the management of breast cancer supports the possibility of local excision and sentinel lymph node identification as a possible alternative to inguinofemoral lymphadenectomy.
