Efficacy of naloxegol on symptoms and quality of life related to opioid-induced constipation in patients with cancer: a 3-month follow-up analysis

Objectives: Opioid-induced constipation (OIC) can affect up to 63% of all patients with cancer. The objectives of this study were to assess quality of life as well as efficacy and safety of naloxegol, in patients with cancer with OIC. Methods: An observational study was made of a cohort of patients with cancer and with OIC exhibiting an inadequate response to laxatives and treated with naloxegol. The sample consisted of adult outpatients with a Karnofsky performance status score ≥50. The Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) and the Patient Assessment of Constipation Symptoms (PAC-SYM) were applied for 3 months. Results: A total of 126 patients (58.2% males) with a mean age of 61.3 years (range 34-89) were included. Clinically relevant improvements (>0.5 points) were recorded in the PAC-QOL and PAC-SYM questionnaires (p<0.0001) from 15 days of treatment. The number of days a week with complete spontaneous bowel movements increased significantly (p<0.0001) from 2.4 to 4.6 on day 15, 4.7 after 1 month and 5 after 3 months. Pain control significantly improved (p<0.0001) during follow-up. A total of 13.5% of the patients (17/126) presented some gastrointestinal adverse reaction, mostly of mild (62.5%) or moderate intensity (25%). Conclusions: Clinically relevant improvements in OIC-related quality of life, number of bowel movements and constipation-related symptoms were recorded as early as after 15 days of treatment with naloxegol in patients with cancer and OIC, with a good safety profile

Metodología experimental aplicada a la Inmunología Molecular

El objetivo general del proyecto es aplicar un modelo pedagógico en el que participen los alumnos de manera activa y apliquen el método científico en base a los conocimientos que han adquirido, resolviendo y realizando un caso práctico en el laboratorio. Integra una estrategia didáctica que va a fomentar la participación activa del alumnado provocando un aprendizaje significativo, ya que el alumno tiene que resolver mediante el razonamiento un caso práctico y luego integrarlo en el laboratorio con el uso de una técnica ampliamente utilizada en Inmunología, como es la citometría de flujo.Depto. de Arquitectura de Computadores y AutomáticaFac. de InformáticaFALSEInnovasubmitte

Supinidine Viridiflorates from the Roots of Chromolaena pulchella

The alkaloid extract from the roots of Chromolaena pulchella provided two new pyrrolizidine alkaloids, elucidated as (–)-supinidine triviridiflorate (1) and (–)-supinidine diviridiflorate (2) based on their physical and spectroscopic properties. Their absolute configuration was determined by chemical correlation with (–)-supinidine (3) and (+)-viridifloric acid (4)
