- Asdas responses in patients with axial spondyloarthritis starting bdmards: results from a multicentre prospective cohortPublication . Santos, M. E.; Ramiro, S.; Van der Heijde, D.; Landewé, R.; Santos, F. Pimentel; Machado, A. R. Cruz; Ferreira, C.; Gomes, C.; Soares, C. Dantas; Miguel, C.; Albuquerque, F.; Martins, F.; Silva, L.; Santos, H.; Almeida, I.; Bernardes, M.; Khmelinskii, N.; Valente, P.; Teixeira, P. M.; Matias, S. Emídio; Fraga, V.; Branco, J. C.; Sepriano, A.ASAS and EULAR recommend the use of an improvement ≥1.1 in ASDAS at 12 weeks to determine the continuation of a bDMARD. However, it is debated whether improvements can occur and whether patients’ characteristics influence (time to) response.
- Baseline climatology of the Canary Current Upwelling System and evolution of sea surface temperaturePublication . Mills, Lara; Janeiro, João; Martins, F.Global climate change has induced a rise in sea surface temperature (SST), although this increase is not uniform across the world. Significant variations exist between coastal and offshore waters, particularly in regions affected by upwelling processes. This study focuses on the Canary Current Upwelling System (CCUS), stretching from Northwest Iberia to Northwest Africa. High-resolution remotely sensed SST data (0.05°) from the ODYSSEA Level 4 Sea Surface Temperature Reprocessed dataset were validated with in situ measurements and employed to establish a regional climatological baseline for 1982–2012. Subsequent years were compared to this baseline to construct SST anomaly maps, revealing SST changes since 2012. The study area was further divided into sub-regions for comparative analysis. Results indicate that SST consistently increased at a higher rate offshore compared to the adjacent nearshore regions. A reference dataset spanning 1951–1981 was used to gauge SST variability between the two baselines. SST exhibited a 0.59 °C increase from 1951–1981 to 1982–2012, with a slowing of SST trends beyond the 1982–2012 baseline. This research offers valuable insights into the climatological dynamics of the CCUS. These findings enhance our understanding of this critical coastal system’s climatology, laying the groundwork for future investigations into evolving climate patterns in coastal regions.
- Cloning, characterization and in vitro and in planta expression of a glucanase inhibitor protein (GIP) of Phytophthora cinnamomiPublication . Martins, I.; Martins, F.; Belo, H.; Vaz, M.; Carvalho, M.; Cravador, A.; Choupina, A.Oomycetes from the genus Phytophthora are fungus-like plant pathogens that are devastating for agriculture and natural ecosystems. They are able to secrete a glucanase inhibitor protein (GIP) that inhibits the activity of endoglucanases (EGases) involved in defense responses against infection. One of the most widely distributed and aggressive Phytophthora species, with more than 1,000 host plants is P. cinnamomi. In this work we report the sequencing and characterization of a class of GIPs secreted by Phytophthora cinnamomi. The gip gene from P. cinnamomi has a 937 bp ORF encoding a putative peptide of 312 deduced amino acids. The expression of this gene was studied during growth in different carbon sources (glucose, cellulose and sawdust), by RT-qPCR and its level of expression was evaluated at five time points. The highest expression of gip gene occurred in sawdust at 8 h of induction. In vivo infection of C. sativa revealed an increase in gip expression from 12 to 24 h. At 36 h its expression decreased suggesting that a compensatory mechanism must occur in plant.
- Wunderlich syndrome as a rare complication of polyarteritis nodosa: a case reportPublication . Oliveira, D.; Martins, A.; Martins, F.; Rato, M.; Pinheiro, F.; Fonseca, D.; Vaz, C.; Mariz, E.; Costa, L.Spontaneous subcapsular and perirenal hemorrhage, known as Wunderlich syndrome (WS), is a rare clinical manifestation of polyarteritis nodosa (PAN). We report a case of a 48-year-old male with a history of recurrent episodes of leg muscle tenderness and dysesthesia, bilateral flank pain, painful nodular skin lesions in the lower limbs, weight loss, and difficult-to-control arterial hypertension. The abdominopelvic computed tomography angiography showed a large left perirenal hematoma, leading to the patient's admission to the intensive care unit. After the exclusion of infectious or neoplastic foci, the patient was diagnosed with PAN and started intravenous methylprednisolone pulses with a good response. Since WS is a rare initial clinical manifestation of PAN, an early diagnosis and aggressive treatment will significantly improve clinical outcomes.
