- Advancing diabetes treatment: from human beta cell technology to bioartificial pancreas developmentPublication . Sá, Joana; Sá, Simone; Leménager, Hélène; Costa, Raquel; Onteniente, Brigitte; Soares, Raquel; Ribeiro, Viviana P.; Oliveira, Ana L.In 2021, approximately 537 million people worldwide, primarily in low- and middle-income countries, were affected by diabetes, leading to approximately 6.7 million deaths annually or severe secondary complications including life-threatening hyperglycemia. For nearly 50 years, current therapeutic approaches include full pancreas transplantation and isolated pancreatic islets, more recently, cell therapy such as in vitro generated islets and stem cell derived. The transplantation of pancreatic islet cells can be less invasive than full organ transplantation, however, does not achieve the same rate of functional success due to the low survival of the engrafted cells. Tissue-engineered bioartificial pancreas has been designed to address such issues, improving cell engraftment, survival, and immune rejection problems, with the added advantage that the tissue produced in vitro has an unlimited source of material.
- Media multitasking scale: validation study with Portuguese adolescentsPublication . Campos, Luísa; Nobre, Bárbara; Morais, Catarina; Veríssimo, Lurdes; Dias, Pedro; Luo, JiutongThe increasing presence of digital media has amplified the need to study media multitasking (both multiple media activities simultaneously and using media while doing non-media activities). Media Multitasking Scale (MMS) has been used to assess this phenomenon, but it is yet to be validated for a Portuguese population. This study analysed the validity of a Portuguese Version of the MMS (n = 171 Portuguese adolescents) based on inter-item correlations and confirmatory factor analysis. The results suggest changes in the original version to reflect more recent digital media tendencies for a better fit to the Portuguese adolescents’ sample. Additionally, results showed that Multitasking with Media and Non-Media and Concentration Without Multitasking were partially predictors of mental health problems (predictive validity), highlighting the scale’s utility in assessing media multitasking behaviours and their impact on psychological well-being.
