Consensus document of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC), the Spanish Society of Otorhinolaryngology and Head and Neck Surgery (SEORL-CCC) and the Spanish Society of Anesthesiology and Resuscitation (SEDAR) on tracheotomy in patients with COVID-19 infection.

La alta incidencia de insuficiencia respiratoria aguda en el contexto de la pandemia por COVID-19ha conllevado el uso de ventilación mecánica hasta en un 15%. Dado que la traqueotomía es un procedimiento quirúrgico frecuente, este documento de consenso, elaborado por tres Sociedades Científicas, la SEMICYUC, la SEDAR y la SEORL-CCC, tiene como objetivo ofrecer una revisión de las indicaciones y contraindicaciones de traqueotomía, ya sea por punción o abierta, esclarecer las posibles ventajas y exponer las condiciones ideales en que deben realizarse y los pasos que considerar en su ejecución. Se abordan situaciones regladas y urgentes, así como los cuidados postoperatorios.post-print393 K

Carcinomas atípicos de la laringe. Descripción de dos casos

95% of the malignant neoplasm of the larynx are squamous carcinoma. Neuroendocrine carcinomas correspond to at least 1 % of laryngeal tumors. The supraglottic is the most frequent laryngeal localization. Diagnosis is based on histological and immunohistochemically characteristic. They are divided into four histological types, which have a different natural evolution and prognosis. Description: We present two cases of laryngeal neuroendocrine carcinomas. One of them belongs to a small cell neuroendocrine carcinoma and the other one to a large cell carcinoma, which diagnosis generated controversy.El 95% de las neoplasias malignas de laringe son de tipo carcinoma escamoso. Los carcinomas neuroendocrinos corresponden a menos del 1% de los tumores laríngeos. La localización laríngea más frecuente es la supraglotis. El diagnóstico se basa en las características histológicas e inmunohistoquímicas. Se dividen en cuatro tipos histológicos que tienen una evolución natural y pronóstico diferentes. Descripción: Exponemos dos casos de carcinomas neuroendocrinos de la laringe. Uno de ellos pertenece a la estirpe celular de carcinoma de células pequeñas y el otro a un carcinoma de células grandes, cuyo diagnóstico histológico generó controversias

Modification of Breast Cancer Milieu with Chemotherapy plus Dendritic Cell Vaccine: An Approach to Select Best Therapeutic Strategies

Background: The addition of dendritic cell vaccines (DCV) to NAC could induce immune responses in those patients with residual disease (RD) by transforming the tumor microenvironment. Methods: Core diagnostic biopsies and surgical specimens from 80 patients (38 in the vaccinated group plus NAC (VG) and 42 in the control group (CG, treated only with NAC) were selected. We quantify TILs (CD8, CD4 and CD45RO) using immunohistochemistry and the automated cellular imaging system (ACIS III) in paired samples. Results: A CD8 rise in TNBC samples was observed after NAC plus DCV, changing from 4.48% in the biopsy to 6.70% in the surgical specimen, not reaching statistically significant differences (p = 0.11). This enrichment was seen in up to 67% of TNBC patients in the experimental arm as compared with the CG (20%). An association between CD8 TILs before NAC (4% cut-off point) and pathological complete response in the VG was found in the univariate and multivariate analysis (OR = 1.41, IC95% 1.05–1.90; p = 0.02, and OR = 2.0, IC95% 1.05–3.9; p = 0.03, respectively). Conclusion: Our findings suggest that patients with TNBC could benefit from the stimulation of the antitumor immune system by using DCV together with NAC

Minimum information about tolerogenic antigen-presenting cells (MITAP): a first step towards reproducibility and standardisation of cellular therapies

Cellular therapies with tolerogenic antigen-presenting cells (tolAPC) show great promise for the treatment of autoimmune diseases and for the prevention of destructive immune responses after transplantation. The methodologies for generating tolAPC vary greatly between different laboratories, making it difficult to compare data from different studies; thus constituting a major hurdle for the development of standardised tolAPC therapeutic products. Here we describe an initiative by members of the tolAPC field to generate a minimum information model for tolAPC (MITAP), providing a reporting framework that will make differences and similarities between tolAPC products transparent. In this way, MITAP constitutes a first but important step towards the production of standardised and reproducible tolAPC for clinical application
