RESUMO

PURPOSE: A protective loop ileostomy is the most useful method to reduce sequelae in the event of an anastomotic leakage (AL) after rectal cancer surgery. However, it requires an additional stoma reversal surgery with its own potential complications. Postoperative ileus (POI) remains the most common complication after ileostomy reversal, which leads to an increase in morbidity, length of hospital stay (LOS) and overall healthcare costs. Several retrospective studies carried out in this field have concluded that there are insufficient evidence-based recommendations about the routine application of preoperative bowel stimulation in clinical practice. Here we discuss whether stimulation of the efferent limb before ileostomy reversal might reduce POI and improve postoperative outcomes. METHODS: This is a multicentre randomised controlled trial to determine whether mechanical stimulation of the efferent limb during the 2 weeks before the ileostomy reversal would help to reduce the development of POI after surgery. This study was registered on Clinicaltrials.gov (NCT05302557). Stimulation will consist of infusing a solution of 500 ml of saline chloride solution mixed with a thickening agent (Resource©, Nestlé Health Science; 6.4 g sachet) into the distal limb of the ileostomy loop. This will be performed within the 2 weeks before ileostomy reversal, in an outpatient clinic under the supervision of a trained stoma nurse. CONCLUSION: The results of this study could provide some insights into the preoperative management of these patients.

RESUMO

Objetivos: analizar la mejora de la adherencia en pacientes no adherentes con HTA no controlada, polimedicados y mayores de 55 años tras el empleo de sistemas personalizados de reacondicionamiento (SPD). Diseño: estudio longitudinal (6 meses). Se analizaron los niveles de adherencia al tratamiento mediante una adaptación del test de Morisky-Green, contaje de medicación devuelta (en el grupo SPD) y valores de presión arterial. Emplazamiento: estudio multicéntrico en 35 farmacias comunitarias de toda España. Participantes: 195 participantes (88 grupo SPD y 107 grupo control) mayores de 55 años, polimedicados, no adherentes a la medicación, con HTA no controlada y que empleaban receta médica electrónica. Intervenciones: el grupo SPD recibió su medicación en SPD mientras el grupo control recibía su medicación de manera rutinaria. Mediciones principales: a ambos grupos se les realizaron tomas periódicas de sus valores de PAS/PAD mediante tensiómetro digital.Resultados: el grupo SPD obtuvo un descenso significativo de los valores de PA frente al grupo control (la PAS disminuyó en 18,3 mmHg en el grupo SPD vs. 9,9 mmHg en el grupo control y la PAD en 9,9 mmHg vs. 8,9 mmHg). Ambos grupos aumentaron su adherencia hasta superar el 90 %.Conclusiones: el empleo de SPD permitió controlar los niveles de PA a casi un 50 % de los pacientes por lo que se postula como una buena herramienta (costo-efectiva, bien tolerada por los usuarios, de fácil uso…) para mejorar la adherencia de los pacientes y controlar la HTA de estos, aunque son necesarios más estudios.

RESUMO

La espasticidad es un fenómeno complejo de expresión clínica extremadamente variable, un proceso dinámico y evolutivo que puede condicionar la funcionalidad y tratamiento del paciente. La recomendación actual de tratamiento temprano persigue evitar su progresión y complicaciones, e implica un planteamiento individualizado basado en un amplio abanico de medidas farmacológicas y no farmacológicas. Esta guía resulta de un foro de especialistas expertos que afrontaron algunas incertezas frecuentes en el proceso de valoración y planteamiento terapéutico como la idoneidad de iniciar tratamiento, consideraciones para iniciar, continuar y cesar el tratamiento con toxina botulínica, tratamientos adyuvantes, el dolor o el seguimiento del paciente espástico. El resultado es un algoritmo de decisión para el abordaje terapéutico de la espasticidad. Tanto el avance científico como el intercambio de experiencia clínica en el que se basa esta guía puede apoyar la toma de decisiones sobre algunas áreas de penumbra que encontramos en la práctica clínica diaria.(AU)


Spasticity is a complex phenomenon of extremely variable clinical expression, a dynamic and evolutionary process that can condition the activity and treatment of the patient. The current recommendation for early treatment aims to avoid progression and complications, and involves an individualized approach based on a wide range of pharmacological and non-pharmacological measures. This guide results from a forum of expert specialists who faced some frequent uncertainties in the assessment process and therapeutic approach of the spastic patient such as the suitability of initiating treatment, considerations for initiating, continuing and ceasing treatment with botulinum toxin, adjuvant treatments, pain or follow-up. The result is one algorithm of decision for the therapeutic approach of spasticity. Both scientific progress and the exchange of clinical experience on which this guide is based, can support decision-making on some areas of gloom that we find in daily practice.(AU)

RESUMO

OBJECTIVE: To study gastroesophageal reflux (GER) in children undergoing gastrostomy in a single pediatric institution. MATERIAL AND METHODS: A retrospective study of patients undergoing gastrostomy from 2000 to 2017 was carried out. Demographic data, clinical data, progression, and complications were recorded. GER was considered positive in patients with clinical signs requiring antisecretory treatment, prokinetic treatment, or anti-reflux surgery to control symptoms. RESULTS: 207 patients with a median age of 2 years [R: 0.25-18] were included. Neurological impairment was the most frequent underlying condition (74%). Swallowing difficulty and undernourishment were the main surgical indications for gastrostomy. Prior to gastrostomy, 96 out of 207 patients (46%) showed GER symptoms. Combined fundoplication and gastrostomy was performed in 41 (43%) patients with preexisting GER, 6 of whom showed GER worsening (4 required redo fundoplication). 5 complications following fundoplication were noted - gastric perforation, sustained Dumping syndrome, and gastroesophageal stenosis. 55 out of 96 (57%) patients with preexisting GER underwent gastrostomy alone. Clinical signs disappeared in 16 of them (29%) and improved or stabilized in 19 (35%). GER worsening occurred in 20 patients (36%), with subsequent fundoplication being required in 10 cases. In patients with no previous clinical signs (111 out of 207), GER symptoms occurred following gastrostomy in just 18 cases (16%), and only 2 patients required fundoplication. CONCLUSIONS: In our experience, routine anti-reflux surgery combined with gastrostomy is not justified. Individualized fundoplication should be considered in case of medical treatment failure. Further studies with an adequate design are required to establish which patients could really benefit from this procedure.


OBJETIVO: Estudio del reflujo gastroesofágico (RGE) en los pacientes en los que se ha realizado una gastrostomía en nuestro centro. MATERIAL Y METODOS: Revisión de los pacientes intervenidos de gastrostomía en el periodo 2000-2017. Registro de datos demográficos, clínicos, evolución y complicaciones. Definimos RGE como la presencia de clínica compatible en pacientes que requirieron tratamiento médico o quirúrgico antirreflujo. RESULTADOS: Incluimos 207 pacientes con una mediana de edad de 2 años [r:0,25-18]. La patología subyacente más frecuente fue déficit neurológico (74%). Las indicaciones quirúrgicas fueron trastornos deglutorios y/o desnutrición. Previamente a la gastrostomía, 96/207 pacientes (46%) presentaban clínica de RGE. Se realizó funduplicatura asociada a gastrostomía en 41/96 (43%) de los pacientes con RGE previo. En 6/41 pacientes (15%) el RGE empeoró, requiriendo 4 de ellos una segunda funduplicatura. Se registraron 5 complicaciones tras funduplicatura (perforaciones gástricas, síndromes de Dumping prolongados y estenosis esofagogástrica). En 55/96 pacientes con RGE previo a la gastrostomía no se asoció funduplicatura. La clínica desapareció en 16/55 (29%), y mejoró o se estabilizó en 19/55 pacientes (35%). En 20/55 (36%) la sintomatología empeoró, y 10 de ellos precisaron una funduplicatura posterior. De los pacientes sin clínica previa de RGE (111/207), presentaron síntomas de RGE tras la gastrostomía 18/111 (16%), y solo 2 pacientes requirieron funduplicatura. CONCLUSIONES: Según nuestra experiencia, la funduplicatura de rutina asociada a la gastrostomía no está justificada. En caso de fracaso del tratamiento médico del RGE, una técnica antirreflujo debe plantearse de forma individualizada. Son necesarios estudios adecuadamente diseñados para definir qué pacientes realmente se beneficiarían de este procedimiento.

RESUMO

A correct preoperative strategy is crucial when surgery is needed for retrorectal tumours (RRT).[1] Surgical approaches may be purely anterior-abdominal, posterior-sacrococcygeal or combined depending on the tumour's size and location.[2] We present the case of an 18-year-old female with Currarino Syndrome who underwent surgery by a combined abdominal laparoscopic-posterior Kraske approach for the resection of a large RRT.

RESUMO

Purpose. Neoadjuvant chemotherapy is being actively tested as an emerging alternative for the treatment of locally advanced colon cancer (LACC) patients, resembling its use in other gastrointestinal tumors. This study assesses the mid-term oncologic outcome of LACC patients treated with oxaliplatin and fluoropyrimidines-based preoperative chemotherapy followed by surgery. Methods and patients. Patients with radiologically resectable LACC treated with neoadjuvant therapy between 2009 and 2014 were retrospectively analyzed. Radiological, metabolic, and pathological tumor response was assessed. Both postoperative complications, relapse-free survival (RFS), and overall survival (OS) were studied. Results. Sixty-five LACC patients who received treatment were included. Planned treatment was completed by 93.8 % of patients. All patients underwent surgery without delay. The median time between the start of chemotherapy and surgery was 71 days (65-82). No progressive disease was observed during preoperative treatment. A statistically significant tumor volume reduction of 62.5 % was achieved by CT scan (39.8-79.8) (p < 0.001). It was also observed a median reduction of 40.5 % (24.2-63.7 %) (p < 0.005) of SUVmax (Standard Uptake Value) by PET-CT scan. Complete pathologic response was achieved in 4.6 % of patients. Postoperative complications were observed in 15.4 % of patients, with no cases of mortality. After a median follow-up of 40.1 months, (p25-p75: 27.3-57.8) 3-5 year actuarial RFS was 88.9-85.6 %, respectively. Five-year actuarial OS was 95.3 %. Conclusion. Preoperative chemotherapy in LACC patients is safe and able to induce major tumor regression. Survival times are encouraging, and further research seems warranted (AU)

RESUMO

Background and objectives: The standard treatment for locally advanced rectal cancer (LARC) is neoadjuvant chemoradiotherapy (CRT) followed by surgery. Pathological findings remain the most significant prognostic factor. The presence of mucin pools and their prognostic significance is a controversial issue. The aim of this study was to analyze the incidence of cellular and acellular mucin pools and their clinical significance. Methods: Four-hundred and forty-six consecutive prospectively collected specimens from patients with LARC treated with long-course preoperative CRT and surgery were analyzed. Kaplan-Meier analysis was performed. Results: Mucin pools were present in 182 specimens (40.8 %); 66 (14.7 %) were acellular, and viable tumor cells were identified in 116 (26 %). The complete pathological response rate was 13.5 % (60 of 446). With a median follow-up of 79.0 months, the 5- and 10-year disease-free survivals for patients with acellular and cellular mucin pools were 81.5, 78.1, 63.7 and 61.2 %, respectively (p B 0.026). The presence of cells in the colloid response to treatment was associated with a 17.8 and 16.9 % decrease in 5- and 10-year disease survival vs. acellular colloid response. Conclusions: Our results suggest that cellular mucin pools are an indicator of an aggressive phenotype and harbingers of a worse prognosis (AU)

RESUMO

Polo-like kinase 1 (PLK1) is a serine/threonine-protein kinase expressed during mitosis and overexpressed in multiple human cancers, including leukemia and also many solid tumors. PLK1 knockdown has been shown to block proliferation of leukemic cell lines and the clonogenic potential of tumor cells grown from patients with cancer. PLK1 inhibition is a promising strategy for the treatment of some tumors. We aim to analyze expression of PLK1 in metastatic colorectal carcinoma. Retrospective analysis of colorectal carcinomas with hepatic metastasis during follow-up receiving neoadjuvant chemotherapy (NAC), based on oxaliplatin. Immunohistochemistry for PLK-1 in paraffin-embedded tissue from the primary and also from the metastasis. 50 patients. 32% showed good histopathological response. 43% of the primaries were positive for PLK1, as opposed to 23.5% of the metastasis. Expression of PLK1 was significantly reduced in metastasis compared with the primaries (p = 0.05), what could be due to therapy or to a phenotypic change of the metastatic nodule. Analysis of the prognostic influence of PLK1 expression showed significant association between PLK1 expression in metastasis and lower overall survival (p = 0.000). We have also found a significant association between PLK1 expression and histopathological response (p = 0.02). All the tumors with high expression of PLK1 showed minor response (11/11). This study shows the association between survival and poor histopathological response to therapy and high expression of PLK1 in metastasis. Our results could open a new therapeutic approach through the inhibition of PLK1.

RESUMO

This study set out to evaluate the effectiveness of low speed autonomous emergency braking (AEB) technology in current model passenger vehicles, based on real-world crash experience. The validating vehicle safety through meta-analysis (VVSMA) group comprising a collaboration of government, industry consumer organisations and researchers, pooled data from a number of countries using a standard analysis format and the established MUND approach. Induced exposure methods were adopted to control for any extraneous effects. The findings showed a 38 percent overall reduction in rear-end crashes for vehicles fitted with AEB compared to a comparison sample of similar vehicles. There was no statistical evidence of any difference in effect between urban (≤60 km/h) and rural (>60 km/h) speed zones. Areas requiring further research were identified and widespread fitment through the vehicle fleet is recommended.

RESUMO

Introducción: La obesidad infantil ha sido definida por la Organización Mundial de la Salud como la epidemia del siglo XXI. Tradicionalmente, la dieta mediterránea y el ejercicio físico han sido los pilares para prevenirla. El objetivo de este trabajo es conocer la relación actual entre la dieta y el ejercicio con el sobrepeso/obesidad. Material y métodos: Se realizaron entrevistas a los niños que acudieron a la revisión de los 11 años empezando por la encuesta enKid, para valorar la alimentación, y añadimos unas preguntas sobre horas de sueño, horas de «ocio de pantalla» y horas de actividades deportivas extraescolares. Resultados: Del análisis de las respuestas se desprende que el 42,7% de los encuestados sigue una alimentación mediterránea óptima, el 4,82% una dieta de mala calidad y el resto una dieta que necesita mejorar. La prevalencia de sobrepeso en ambos sexos fue del 29,52% y la de obesidad del 13,25%. Las horas de sueño fueron insuficientes, las actividades deportivas extraescolares satisfactorias, y el ocio de pantalla no sobrepasó los límites aceptables. Conclusiones: En atención primaria se debe seguir trabajando para prevenir la obesidad infantil. Asimismo, hay que intentar aprovechar las revisiones de salud escolar para insistir en los beneficios de la dieta mediterránea, aconsejar dormir las horas de sueño adecuadas a cada edad y fomentar las actividades deportivas (AU)
