New forms of induction of apoptosis in aggressive lymphoma using peptides that interrupt the RAS / RAF interaction

Interpretation: RAS-RAF-MEK-ERK is a key pathway for apoptosis regulation in cancer cells. B-Raf-inhibitors such as PLX4032 peptide was developed by Institute Curie-Université Pierre et Marie Curie in order to induce apoptosis in cancer cells. Objectives: To demonstrate pro-apoptotic properties and survival outcome of EP2014/064243 peptide in murine aggressive lymphoma. Material and Methodology: BALBc mice with T-lymphoma were randomized assigned either in Group A (peptide+cyclophosphamide-CFM); Group B (peptides), Group C (CFM-control) or Control D (Cl-Na 0.9%-SF control group). Survival probability was calculated by Kaplan-Meier analysis. Apoptosis was detected using TUNEL technique. The protocol was approved by the Institutional Committee for Animal Care (CICUAL: T04-01-2015) Results: The median survival was 24 days (21.6-26.4) for placebo, 33 days (28.0-35.4) for the CFM monotherapy group, 33 (27.1-35.8) for the peptide group and 34 days (24,4-40) for CFM-peptide combined treatment (p<0.05). In lymph node tissue the mean TUNEL positive cells per field for each treatment group was 2, 12 and 13 and 35 for SF, CFM, peptide and combined therapy (p<0.05). Conclusion: These findings suggest that in murine aggressive lymphoma treated by an experimental peptide in addition with CFM, had an exponentially pro-apoptotic effect than CFM alone, suggesting that the peptide potentiated the anti-tumoural effect of CFM.

Registro del Grupo NADYA-SENPE de Nutrición Enteral Domiciliaria en España; años 2016 y 2017 / Spanish home enteral nutrition registry of the year 2016 and 2017 from the NADYA-SENPE Group

Objetivo: exponer los resultados del registro de nutrición enteral domiciliaria (NED) de los años 2016 y 2017 del Grupo NADYA-SENPE. Material y métodos: se recopilaron los pacientes introducidos en el registro del 1 de enero al 31 de diciembre de 2016 y la mismas fechas de 2017 para proceder al análisis descriptivo y analítico de los datos. Resultados: en el año 2016 se obtuvieron 4.578 pacientes activos (prevalencia = 98,33 pacientes/millón de habitantes) y en 2017 fueron 4.777 (prevalencia = 102,57). Por sexos, hubo un 50,8% de varones en 2016 y un 50,5% en 2017. En el periodo 2016-17, la edad mediana fue de 71,5 años (IIQ 57-83); asimismo, finalizaron 1.558 episodios de NED y la causa principal fue el fallecimiento (793 pacientes, 50,89%). Los varones adultos fueron más jóvenes que las mujeres (65,3 vs. 73,3 años, p-valor < 0,001) y el diagnóstico más frecuente fue la enfermedad neurológica que cursa con afagia o disfagia severa (59%). La sonda nasogástrica (SNG) fue la vía de acceso más utilizada (48,3%) y se observa, además, que esta es la vía que se utiliza en los pacientes más ancianos (p < 0,001). Se registraron 126 pacientes pediátricos (57,1% niñas). La edad mediana de inicio de la NED fue de cuatro meses. Otras patologías fue el grupo diagnóstico más registrado (41,3%), seguido por la enfermedad neurológica que cursa con afagia o disfagia severa. Se alimentaban a través de gastrostomía en el 57,6% de los casos. Se observó que los niños más pequeños eran los que se alimentaban preferentemente por SNG (p-valor 0,001). Conclusiones: el número de pacientes del registro, así como el número de centros participantes, se va incrementando progresivamente. Las principales características de los pacientes no han variado. A pesar del aumento de posibilidades diagnósticas en la población pediátrica, llama la atención la clasificación dentro del grupo de Otras patologías

Objective: to present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the year 2016 and 2017. Material and methods: from January 1st 2016 to December 31st 2017, the HEN registry was recorded and afterwards a further descriptive and analytical analysis was done. Results: in 2016, 4,578 active patients were recorded and prevalence was 98.33 patients per one million inhabitants; in 2017, 4,777 patients were recorded, with a prevalence of 102.57 per one million inhabitants; 50.8% were males in 2016 and 50.5% in 2017. During the period 2016-17, median age was 71.5 years (IIQ 57-83), 1,558 HEN episodes were finished and the main cause was death (793 patients, 50.89%). Adult males were younger than females (65.3 vs. 73.3 years, p-value < 0.001). The most frequent diagnosis was the neurological disorder that presents with aphagia or severe dysphagia (59%). Nasogastric tube was the most frequent administration route (48.3%) and it is the most widely used in elderly patients (p < 0.001). One hundred and twenty-six pediatric patients were registered (57.1% females). Median age at the beginning of HEN in children was four months. "Other disorders" was the most recorded diagnostic group (41.3%), followed by the group of neurological disorder that presents with aphagia or severe dysphagia. Regarding children, 57.6% were fed through gastrostomy and the younger ones were fed through nasogastric tube (p-value 0.001). Conclusions: the number of patients in the registry, as well as the number of participating centers, is progressively increasing. The main characteristics of the patients have not changed. Despite the increase in diagnostic possibilities in the pediatric population, the classification within the group of "Other pathologies" is quite significant

[An integrated medical image network of patient records: experience of the Picture Archiving and Communication System (PACS) of the Gustave-Roussy Institute]. / Un réseau d'images médicales intégrées au dossier du patient: expérience du Picture Archiving and Communication System (PACS) de l'Institut Gustave-Roussy.

The PACS (Picture Archiving and Communication System) is a central radiologic image archiving system coupled with an information system which allows rapid access to these images. It permits rapid access of the entire file of radiologic images of a patient for radiologists and clinicians. After installation of an MRI and CT scan unit at the IGR, a PACS system was installed in July, 2000. The preparation phase and characteristics of the PACS system at the IGR are described here. The data in the literature and the short experience of the PACS system at the IGR show benefits of this system at several levels: improved efficiency (for technicians, radiologists, and secretaries), improved image quality and interpretation, improved clinical management of patients resulting from more timely image interpretation and execution of clinical decisions, increased ease of image transfer for tele-imagery, and improved teaching and publication possibilities. The PACS significantly modifies work habits since the interpretation and consultation of images is done exclusively at the console and progressively obviates the need for actual films.
