[EN] The induction of senescence produces a stable cell cycle arrest in cancer cells, thereby inhibiting tumor growth; however, the incomplete immune cell-mediated clearance of senescent cells may favor tumor relapse, limiting the long-term anti-tumorigenic effect of such drugs. A combination of senescence induction and the elimination of senescent cells may, therefore, represent an efficient means to inhibit tumor relapse. In this study, we explored the antitumor efficacy of a combinatory senogenic and targeted senolytic therapy in an immunocompetent orthotopic mouse model of the aggressive triple negative breast cancer subtype. Following palbociclib-induced senogenesis and senolysis by treatment with nano-encapsulated senolytic agent navitoclax, we observed inhibited tumor growth, reduced metastases, and a reduction in the systemic toxicity of navitoclax. We believe that this combination treatment approach may have relevance to other senescence-inducing chemotherapeutic drugs and additional tumor types. Significance: While the application of senescence inducers represents a successful treatment strategy in breast cancer patients, some patients still relapse, perhaps due to the subsequent accumulation of senescent cells in the body that can promote tumor recurrence. We now demonstrate that a combination treatment of a senescence inducer and a senolytic nanoparticle selectively eliminates senescent cells, delays tumor growth, and reduces metastases in a mouse model of aggressive breast cancer. Collectively, our results support targeted senolysis as a new therapeutic opportunity to improve outcomes in breast cancer patients., The M.O. laboratory members thank the financial support from the Spanish Government (project SAF2017-84689-R (MINECO/AEI/FEDER, EU)) and the Generalitat Valenciana (project PROMETEO/2019/065).

Background: The optimal management of major bleeding in patients receiving vitamin K antagonists (VKA) for venous thromboembolism (VTE) is unclear.Methods: We used the RIETE (Registro Informatizado Enfermedad TromboEmbolica) registry to assess the management and 30-day outcomes after major bleeding in patients receiving VKA for VTE.Results: From January 2013 to December 2017, 267 of 18,416 patients (1.4%) receiving long-term VKA for VTE had a major bleeding (in the gastrointestinal tract 78, intracranial 72, hematoma 50, genitourinary 20, other 47). Overall, 151 patients (57%) received blood transfusion; 110 (41%) vitamin K; 37 (14%) fresh frozen plasma; 29 (11%) pro-haemostatic agents and 20 (7.5%) a vena cava filter. During the first 30 days, 59 patients (22%) died (41 died of bleeding) and 13 (4.9%) had a thrombosis. On multivariable analysis, patients with intracranial bleeding (hazard ratio [HR]: 4.58; 95% CI: 2.40-8.72) and those with renal insufficiency at baseline (HR: 2.73; 95% CI: 1.45-5.15) had an increased mortality risk, whereas those receiving vitamin K had a lower risk (HR: 0.47; 0.24-0.92). On the other hand, patients receiving fresh frozen plasma were at increased risk for thrombotic events (HR: 4.22; 95% CI: 1.25-14.3).Conclusions: Major bleeding in VTE patients receiving VKA carries a high mortality rate. Intracranial bleeding and renal insufficiency increased the risk. Fresh frozen plasma seems to increase this risk for recurrent VTE.

Objetivo. En este estudió se pretendió un objetivo doble; 1) Constatar las diferencias entre niños asmáticos con sobrepeso y normopeso en cuanto a CVRS y cantidad de actividad física y sedentarismo y 2) Determinar la relación existente entre cantidad de actividad física, sedentarismo e IMC y su influencia en la CVRS de esta población en Sevilla. Método. Se usó un diseño de cohorte que incluyó a 69 niños en edad escolar con asma persistente controlado. Las medidas incluidas en el estudio fueron: el cuestionario PAQL(S), para evaluar la CVRS de los niños y el cuestionario IPAQ-A, para evaluar la cantidad de actividad física y sedentarismo de los niños. También se calculó el IMC y se determinó si el participante estaba en normopeso o sobrepeso. Resultados. Los niños con sobrepeso obtuvieron peores valores en CVRS e IPAQ-A que sus pares con normopeso. Además se observaron correlaciones positivas entre el IMC y la cantidad de sedentarismo y negativas entre el IMC y también entre éste y el valor en las escalas de valoración de la CVRS. Conclusión. El IMC afecta negativamente a la CVRS a los niños asmáticos en edad escolar. Palabras clave: niños asmáticos, enfermedad crónica, hábitos de vida, ejercicio físico.Abstract: Objective. The aim of this study was: 1) To determine the differences between normal-weight asthmatic children and overweight asthmatic children in terms of HRQoL and amount of physical activity and sedentary and 2) To determine the relationship between amount of physical activity, sedentary and BMI and their influence on the HRQoL of this population in Seville. Method. We used a cohort design study that included 69 school-age children with controlled persistent asthma. The measures included in the study were: the questionnaire PAQL (S), to assess the HRQoL of children and the IPAQ-A questionnaire to assess the amount of physical activity and sedentary lifestyle of children. BMI was also calculated and determined if the participant was of normal-weight or overweight. Results. Overweight children scored worse on HRQoL and IPAQ-A values than their peers with normal-weight. Positive correlations were also observed between BMI and the amount of sedentary lifestyle. Negative correlations were observed between BMI and the amount of physical activity and also negative correlations were observed between BMI and HRQoL. Conclusion. BMI negatively affect HRQoL in school- age asthmatic children. Key words: asthmatic children, chronic disease, lifestyles, physical exercise.

Resumen En el entorno neumologico no es habitual conocer las normativas europeas y de EE. UU. que regulan la administracion de oxigeno durante los viajes en avion y la politica a tal respecto que cada compania aerea tiene. Este desconocimiento se debe en gran parte a la escasez de articulos que abordan este tema en las revistas especializadas y a la llamativamente limitada informacion que nos proporcionan las aerolineas en sus paginas web. En este articulo hemos abordado estas normativas, la politica que siguen algunas aerolineas y determinados aspectos practicos que deberiamos tener en cuenta, para que podamos responder de forma satisfactoria a las preguntas que, en un momento puntual, nos pueda plantear un paciente que necesite utilizar oxigeno durante los viajes en avion.

It is unusual for pulmonologists to be familiar with the European and US regulations governing the administration of oxygen during air travel and each airline's policy in this respect. This lack of knowledge is in large part due to the scarcity of articles addressing this matter in specialized journals and the noticeably limited information provided by airlines on their websites. In this article we examine the regulations, the policies of some airlines and practical aspects that must be taken into account, so that the questions of a patient who may need to use oxygen during a flight may be answered satisfactorily.
