- Biologic disease-modifying antirheumatic drugs survival in late-onset axial spondyloarthritis — data from a Portuguese registryPublication . Silva, Susana P.; Monteiro, Beatriz; Oliveira, Cláudia Pinto; Costa, Roberto Pereira da; Matos, Carolina Ochôa; Lopes, Mariana Diz; Gomes, Carlos Marques; Bernardes, Miguel; Santos, Mariana Emília; Gago, Laura; Abreu, Catarina; Fraga, Vanessa; Mendes, Beatriz; Rocha, Margarida Lucas; Soares, Catarina Dantas; Silva, Cândida; Santos, Helena; Valente, Paula; Silva, Lígia; Eugénio, Gisela; Barcelos, AnabelaObjectives Although axial spondyloarthritis (axSpA) typically begins before age 45, late-onset axSpA (lo-axSpA) has been widely recognized. While existing literature describes this subgroup, data on therapeutic approaches remain limited. Therefore, we aimed to evaluate the efficacy and safety of biologic DMARDs in patients with lo-axSpA.Methods We conducted a retrospective, multicentre, national cohort study using data from the Rheumatic Diseases Portuguese Register. A cut-off age of 45 years was applied to define lo-axSpA. Group differences between early- and late-onset disease activity scores were evaluated, and drug survival was assessed over 12 months. Predictors of drug discontinuation were identified using a Cox proportional hazards model.Results In total, 2256 patients were included, of whom 260 (11.5%) had lo-axSpA. Patients with late-onset disease exhibited significantly higher scores in the Ankylosing Spondylitis Disease Activity Score, Bath Ankylosing Spondylitis Disease Activity Index and Bath Ankylosing Spondylitis Functional Index at baseline, 3, 6 and 12 months. Despite these differences, both groups showed proportional reductions in disease activity scores, indicating a continuous decrease in disease activity over time. Although the late-onset group had a higher discontinuation rate during the first 12 months of treatment, lo-axSpA was not associated with an increased risk of therapy discontinuation. The primary reason for treatment discontinuation in both groups was inefficacy, with low rates of infections and other adverse events observed across the cohort.Conclusion Our study demonstrated that lo-axSpA is not associated with reduced treatment efficacy or compromised safety.

This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

- Measuring quality of life of patients with axial spondyloarthritis for economic evaluationPublication . Hernandez Alava, Monica; Wailoo, Allan; Chrysanthou, Georgios; Barcelos, Filipe; van Gaalen, Floris A; Santos, Helena; Fagerli, Karen Minde; Gago, Laura; Margarida Cunha, Maria; van de Sande, Marleen; Couto, Maura C; Bernardes, Miguel; Ramonda, Roberta; Exarchou, Sofia; PD, Carvalho; van der Heijde, Desirée; Machado, Pedro MObjectives To estimate the relationship between EQ5D (three levels, UK version) and the Ankylosing Spondylitis Disease Activity Score (ASDAS) for use in the economic evaluation of health technologies for people with axial spondyloarthritis (axSpA). To compare against the relationship with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Methods An electronic, prospective, Portuguese, nationwide, rheumatic disease register (Reuma.pt) provided data on 1140 patients (5483 observations) with a confirmed diagnosis of axSpA. We estimated models of EQ5D as a function of ASDAS, alone or in combination with measures of functional impairment, using bespoke mixture models which reflect the complex distributional features of EQ5D. The SPondyloArthritis Caught Early cohort provided data from 344 patients (1405 observations) in four European countries and was used for validation. A previously published model of BASDAI/Bath Ankylosing Spondylitis Functional Index (BASFI) was also used to generate predicted EQ5D scores and model performance compared. Results A non-linear relationship exists between EQ5D from ASDAS. The final model included ASDAS, ASDAS squared, age and age squared and demonstrated close fit in both datasets except where data were sparse for patients with very high levels of disease activity (ASDAS >4). This finding held in the validation dataset. Models that included BASFI improved model fit. The ASDAS based models fit the data marginally less well than models using BASDAI. Conclusions Mapping models linking ASDAS to EQ5D allow results from clinical studies to be used in economic evaluation of health technologies with confidence. There is some loss of information compared with BASDAI but this has only a marginal impact.
- Monte do Carrascal 2 (southern Portugal): insights into lithic technology and intra-site spatial analysis of a Late Mesolithic hunting campPublication . Reis, Helena; Gonçalves, Célia; Santos, Helena; Valera, António CarlosIn this article, the results of the archaeological excavations at the Late Mesolithic site of Monte do Carrascal 2 are presented. The site, located inland, southeast from the contemporary Sado shell middens, comprised two hearths with faunal remains and a set of lithic materials that were analysed techno-typologically, as well as in terms of their spatial distribution through GIS tools (K Ripley Function, Kernel Density Estimation and Nearest Neighbour analysis). The study points to a different functionality of this site when compared to most all other Mesolithic sites known in the region, with its uncommon inland location, suggesting that it was possibly a hunting camp.
- Relatório setor agricultura: vulnerabilidades atuais e futurasPublication . Santos, Helena; Nunes, João Pedro; Morais, Inês; Dias, LuísO clima é um fator determinante para a agricultura. O crescimento, desenvolvimento e produtividade das plantas depende da disponibilidade de água, da radiação solar e é fortemente influenciada pela temperatura, entre outros fatores. Assim, é de esperar que as alterações climáticas venham a ter consequências muito significativas neste setor. Para Portugal, os cenários de evolução climática até ao final do século XXI apontam para condições progressivamente mais desfavoráveis para as atividades agrícolas e florestais, consequência da redução da precipitação, do aumento da temperatura média, do aumento da frequência e intensidade dos eventos climáticos extremos e do aumento da suscetibilidade à desertificação (EAAFAC, 2013). Os efeitos das alterações nas últimas décadas são já sentidos no Mediterrâneo, e em particular no Algarve, sendo observado entre 1980 e 2010 um aumento de 0,37°C na temperatura média, uma diminuição da amplitude térmica, uma diminuição da precipitação na primavera, entre outros (EAAFAC, 2013). Os efeitos destas alterações traduzem-se ainda numa redução da disponibilidade de água no solo, na redução da fertilidade e no aumento dos fenómenos de erosão do solo (Adams et al., 1998), causando impactos na agricultura e alterações nos ciclos e nas populações de insetos e microrganismos, podendo causar ainda problemas graves de pragas e doenças nas culturas (Lindner et al., 2008). Como consequência destes fatores, estudos desenvolvidos a nível da União Europeia projetam uma redução significativa da produtividade agrícola para a região mediterrânica (Kovats et al., 2014).
- Sex and body mass index impact on digit circumference for Leeds Dactylitis Index calculationPublication . António, Manuel Silvério; Rodrigues, Ana Maria; Teixeira, Filipa; Costa, José Tavares; Bernardo, Alexandra; Pimenta, Sofia; Gomes, João Lagoas; Aguiar, Renata; Videira, Taciana; Pinto, Patrícia; Santos, Helena; Sequeira, Graça; Teixeira, Lídia; Ribeiro, Ruy Miguel; Fonseca, João Eurico; Sousa, Elsa VieiraObjective. To estimate digit circumference and the impact of sex and body mass index (BMI) for the calculation of the Leeds Dactylitis Index (LDI) in psoriatic arthritis (PsA) patients with bilateral dactylitis. Methods. Digit circumference of the hands and the foot were measured with a dactylometer and were studied according to sex and BMI (divided in 4 weight categories) in healthy Portuguese subjects, using Student's t-test and One-way ANOVA, respectively. The effect size of sex and BMI were calculated using Cohen's d test and Eta squared, respectively. Multiple linear regression was used to calculate the effect of sex and BMI, as well as their interaction, to create a formula to predict digit circumference. Results. Fifty-nine participants (33 women, 26 men) with a mean BMI of 24.8 were included. Men's mean digit circumferences were statistically higher than those of women (p<0.001), with a large sex effect size in most of the digits. Differences in the mean circumference between the four BMI categories were statistically significant (p<0.05) for all digits, with a large BMI effect size. Sex and BMI were independent variables to predict mean digit circumference (p<0.001). A new tool (based on regression analysis) allowing to estimate the circumference of digits for males and females of different BMIs is presented. Conclusion. Our data allows the calculation of digit circumference for males and females of different BMIs in the Portuguese population; and shows that BMI influences digital circumference supporting BMI inclusion in LDI references tables.
