- Measuring the effect of deprivation on primary health care performance using data envelopment analysis and Malmquist IndicesPublication . Merelie, Holly Bea; Amado, Carla; Pereira dos Santos, SérgioLife expectancy is typically shorter in areas with higher deprivation, highlighting the need for policymakers and health care managers to focus on reducing health inequalities through efficient and effective care. This study aims to assess the impact of deprivation on primary health care performance using data from the National Health Service (NHS) in England. Two methods are applied: Data Envelopment Analysis (DEA) to evaluate the performance of 188 Clinical Commissioning Groups (CCGs), whose duties were recently taken on by the new Integrated Care Systems (ICSs), and the Malmquist Index (MI) to assess deprivation’s effect on performance. The DEA results reveal significant variation among CCGs in equity, efficiency, and effectiveness, indicating substantial room for improvement. The MI results show that while CCGs in more deprived areas had more resources per capita and higher efficiency, they were generally less effective than those in less deprived areas. This emphasizes the need to enhance health and social policies to address persistent health inequalities due to deprivation, a critical challenge for the new ICSs. This study illustrates how DEA and the MI can support policymakers and managers in this effort.
- Unveiling the biotechnological potential of cyanobacteria from the portuguese LEGE-CC collection through lipidomics and antioxidant and lipid-lowering propertiesPublication . de Oliveira, Flavio Luis; Conde, Tiago; Pinho, Marisa; Melo, Tânia; Hentschke, Guilherme Scotta; Urbatzka, Ralph; Pereira, Hugo; Costa, Monya; Vasconcelos, Vitor; Domingues, Maria RosárioCyanobacteria are gram-negative prokaryotic microorganisms composed of both broad morphological and phylogenetic diversity inherited from diverse ecosystems like aquatic, terrestrial, or extremophilic environments. In this study, three cyanobacteria strains from the Blue Biotechnology and Ecotoxicology Culture Collection (LEGE-CC) were obtained from different environments in Portugal. Polyphasic analysis was applied for taxonomic identification. The proximate composition analysis indicated the lipid content (6.2% to 9.1% dry weight (DW)), protein content (28.2% to 62.9% DW), and carbohydrate content (19.5% to 46.1% DW). The fatty acid (FA) profiles of the strains revealed the presence of 19 different FAs, with FA 16:0 found in the highest abundance. The lipidomic analysis revealed 230 lipid species, with Laspinema sp. LEGE 06078 displaying the highest diversity (125 lipid species). These included species-specific and common lipids species that denote biochemical uniqueness that are also carriers of omega-3 FA (n−3). Biological assays exhibited strong antioxidant activity against ABTS•+ and DPPH• in Laspinema sp. LEGE 06078, while Sphaerospermopsis sp. LEGE 00249 was renowned for reducing lipids in zebrafish larvae. The findings are of immense significance on the lipidomics diversity of cyanobacteria in terms of nutrition, health, and biotechnology, such as addressing obesity and sustainable resource production.
- Analysis of the strategic leverage of sport dynamics of sport tourism events through a holistic approachPublication . Martins, Rute Sofia Tavares; Mascarenhas, MargaridaThis study focuses on the development of sport dynamics arising from the strategic leverage of sport events and encompassing the planning of tactics and actions conducive to its implementation. Therefore, the objective of this study aims to analyse the sport dynamic leveraging efforts of the event organizers of two non-mega international events. This investigation included the case study of international open water events hosted in Setúbal, Portugal. Data were collected through: (i) documentary analysis covering the period 2010–2022; (ii) field observation of the two events in 2022; and (iii) 14 post-event semi-structured interviews with representatives of the event organizers and a local partner of the events. The data were examined through content analysis using deductive data categorization. The results highlighted the importance of strategic planning of the benefits of sport events, considering both the increase in sport (active and passive) participation and the strengthening of sport organizational capacity. This expanded vision of the development of sport dynamics can maximize more benefits for the host community. The long-term perspective of leveraging local sport dynamics provided by the study of international sport events emphasized the need for a strategic vision that combines an asset-based approach and a community needs-based approach.
