El Autobús accesible y la movilidad urbana: programas, innovación y tecnología: conclusiones de las jornadas

Habida cuenta de que la jornada de 2005 se dedicó en buena medida en a las ventajas y problemas del vehículo de plataforma baja con arrodillamiento (kneeling) y rampa, en 2006 se buscó abordar otros aspectos de gran importancia, tales como la implantación de nuevas tecnologías de comunicación en vehículos y paradas, y sus posibilidades de futuro. Para ello se contó con la presencia de representantes de distintas empresas e instituciones que en la actualidad están incorporando innovaciones e investigando nuevas formas personalizadas o generales de transmisión de información al usuario, particularmente al usuario con discapacidad. Dos mesas redondas denominadas La Accesibilidad en Evolución I y II trataron estos temas ampliamente. Por otra parte, continuando con el interés por conocer las experiencias municipales de mejora de accesibilidad y movilidad mediante el transporte en autobús, se presentaron los casos de Málaga, Las Palmas de Gran Canaria, Gijón, San Sebastián e Irún (mesas redondas Experiencias Municipales I y II).

Projecte UD-WIFI

La Universitat de Deusto al seu campus de San Sebastià pretén amb aquest projecte gestionar centralitzadament els espais amb cobertura WIFI corresponents a ubicacions concretes i localitzades. Per a això s'acollirà al programa 'Accés a Internet i mobilitat amb WI-FI' promogut per la SPRI (Societat per a la Promoció i Reconversió Industrial), que ofereix subvencions per a la instal·lació de xarxes sense fil amb tecnologia WI-FI ubicades dins de la Comunitat Autònoma de País Basc.

The histone deactylase SIRT6 is a novel tumor suppressor that regulates cancer metabolism.

Report for the scientific sojourn carried out at the University of Aarhus, Denmark, from 2010 to 2012. Reprogramming of cellular metabolism is a key process during tumorigenesis. This metabolic adaptation is required in order to sustain the energetic and anabolic demands of highly proliferative cancer cells. Despite known for decades (Warburg effect), the precise molecular mechanisms regulating this switch remained unexplored. We have identify SIRT6 as a novel tumor suppressor that regulates aerobic glycolysis in cancer cells. Importantly, loss of this sirtuin in non-transformed cells leads to tumor formation without activation of known oncogenes, indicating that SIRT6 functions as a first-hit tumor suppressor. Furthermore, transformed SIRT6-deficient cells display increased glycolysis and tumor growth in vivo, suggesting that SIRT6 plays a role in both establishment and maintenance of cancer. We provide data demonstrating that the glycolytic switch towards aerobic glycolysis is the main driving force for tumorigenesis in SIRT6-deficient cells, since inhibition of glycolysis in these cells abrogates their tumorigenic potential. By using a conditional SIRT6-targeted allele, we show that deletion of SIRT6 in vivo increases the number, size and aggressiveness of tumors, thereby confirming a role of SIRT6 as a tumor suppressor in vivo. In addition, we describe a new role for SIRT6 as a regulator of ribosome biogenesis by co-repressing MYC transcriptional activity. Therefore, by repressing glycolysis and ribosomal gene expression, SIRT6 inhibits tumor establishment and progression. Further validating these data, SIRT6 is selectively downregulated in several human cancers, and expression levels of SIRT6 predict both prognosis and tumor-free survival rates, highlighting SIRT6 as a critical modulator of cancer metabolism. Our results provide a potential Achilles’ hill to tackle cancer metabolism.

Aplicación de un programa integral de actividad física en niños y niñas entre 6 y 12 años con sobrepeso y obesidad

El propósito de este estudio longitudinal prospectivo es abordar un plan integral de actividad física en niños y niñas entre 6 y 12 años que padezcan sobrepeso y obesidad. El programa se llevará a cabo en el Hospital de San Juan de Dios de Barcelona, donde se utilizarán una serie de variables de medida y tests que serán valorados antes, durante y después de este plan integral. Participarán dos profesionales de la salud, un fisioterapeuta y un nutricionista, quienes intervendrán en 20 niños y niñas con sobrepeso y obesidad. La finalidad de este estudio es disminuir el índice de masa corporal (IMC), así como el porcentaje de grasa corporal total (GCT) en los niños y niñas con sobrepeso y obesidad. También se pretende introducir y fomentar hábitos de vida saludables en relación a la actividad física y la alimentación en los niños y niñas y en su entorno familiar.

Inappropriate prescribing to the oldest old patients admitted to hospital: prevalence, most frequently used medicines, and associated factors

Background: Scientific evidence on treatments of chronic diseases in patients 85 years old or older is very limited, as is available information on inappropriate prescription (IP) and its associated factors. The study aimed to describe medicine prescription, potentially inappropriate medicines (PIM) and potentially prescribing omissions (PPO) and their associated factors on this population. Methods: In the context of an observational, prospective and multicentric study carried out in elderly patients admitted to seven Spanish hospitals for a year, a sub-analysis of those aged 85 years and over was performed. To assess PIMs, the Beers and STOPP criteria were used, and to assess PPOs, the START and the ACOVE-3 criteria were used. To assess factors associated with IP, a multivariate logistic regression analysis was performed. Patients were selected randomly every week on consecutive days from the hospitalization lists. Results: A total of 336 patients were included in the sub-analysis with a median (Q1-Q3) age of 88 (8690) years. The median medicines taken during the month prior to admission was 10 (713). Forty-seven point two per cent of patients had at least one Beers-listed PIM, 63.3% at least one STOPP-listed PIM, 53.6% at least one START-listed PPO, and 59.4% at least one ACOVE-3-listed PPO. Use of benzodiazepines in patients who are prone to falls (18.3%) and omission of calcium and vitamin D supplements in patients with osteoporosis (13.3%) were the most common PIM and PPO, respectively. The main factor associated with the Beers-listed and the STOPP-listed PIM was consumption of 10 or more medicines (OR = 5.7, 95% CI 1.8-17.9 and OR = 13.4, 95% CI 4.0-44.0, respectively). The main factors associated with the START-listed PPO was a non-community dwelling origin (OR 2.3, 95% CI 1.0-5.0), and multimorbidity (OR1.8, 95% CI 1.0-3.1). Conclusions: Prescribed medicines and PIM and PPO prevalence were high among patients 85 years and over. Benzodiazepine use in those who are prone to falls and omission of calcium and vitamin D in those with osteoporosis were the most frequent PIM and PPO, respectively. Factors associated with PIM and PPO differed with polypharmacy being the most important factor associated with PIM.
