The challenging management of acute mesenteric ischemia - too frail or too late?
Pinelo, Andreia; Loureiro, Luís; Mendes, Daniel; Rocha, Henrique; Almeida, Henrique; Queirós, Miguel; Cabral, João; Machado, RuiINTRODUCTION: acute mesenteric ischemia (AMI) presents a life-threatening emergency, requiring a high degree of suspicion for timely diagnosis. Despite advancements in the management of these patients, in-hospital mortality rates remain high. This study aims to assess the outcomes and prognostic factors in patients with AMI. METHODS: A retrospective single-center analysis of all patients undergoing emergent sur...
Transepiphyseal Fracture‐Dislocation of the Hip inan Adolescent: A Rare Clinic...
Moreira, Andreia G.; Balacó, Inês; Cabral, João; Alves, CristinaHip fracture‐dislocations in children and adolescents are rare and severe injuries. Surgical treatment is urgent and, even with adequate and timely treatment, the complication rate is high. The most common complication is osteonecrosis of the femoral head and the main risk factors include fracture type and displacement. A 13‐year‐old boy presented after a high‐energy trauma, having sustained a fracture‐dislocat...
Pediatric Compartment Syndrome
Viegas, Rui; Viegas, Rui; Carvalho, Marcos; Cabral, João; Sá Cardoso, Pedro; Tarquini, Oliana; Balacó, Inês; Ling, Tah Pu; Alves, CristinaIntroduction: Compartment syndrome (CS) is an orthopedic emergency. Diagnosis is particularly difficult in children because of the challenges inherent to communication and clinical examination. This paper aims to present a pediatric case series of CS and to analyze its etiology, diagnosis, treatment and complications as well as to assess the quality of life of the patients at least 1 year after the event. Metho...
Marine terrace staircases of western Iberia: Uplift rate patterns from rocky li...
Martins, António; Gouveia, Margarida; Cunha, Pedro; Cabral, João; Gomes, Alberto; Falguères, Christophe Falguères; Voinchet, Pierre; Stokes, MartinThe Western Iberian Peninsula is undergoing compressive tectonic reactivation, resulting in spatial and temporal variations of surface uplift. Uplift quantification can be undertaken in coastal settings using staircases of shore platforms developed onto rocky headlands. This study analyses two marine terrace staircases in central Portugal: Cape Raso - Abano beach and Cape Espichel. Geomorphic and stratigraphic ...
Gathering information of cryptic species: Insights from Integrated Occupancy M...
Martins, Frederico; Barros, Paulo; Cabral, João; Segurado, Pedro; Marques, J. TiagoEffective conservation planning relies on an adequate understanding of species occurrence at both individual and community levels. However, detecting some species presents a challenge, and the efficiency of sampling methods varies. Data integration from multiple methods is a natural solution to address these issues and enhance species parameter estimation. This study explores the benefits of combining sampling ...
Reappraisal of active tectonics of the Porto Alto buried fault zone (Portugal) ...
Carvalho, João; Cabral, João; Ghose, Ranajit; Borges, José Fernando; Dias, RubenABSTRACT: The Lower Tagus Valley area (LTV), where Lisbon is located, has been affected by several destructive, M 6+ earthquakes whose sources remain to be determined. The identification of expectable surface or near surface ruptures in the area is a challenging task that requires a multidisciplinary analysis that includes geophysical techniques, as the source faults are mainly buried despite likely to deform U...
Deformação tectónica no bordo ocidental da bacia de Rio Maior : a falha do Cidral
Ressurreição, Ricardo; Dias, Ruben Pereira; Cabral, João; Charifo, G.SUMMARY: The Rio Maior basin is a NNW-SSE elongated tectonic basin, controlled by main faults with the same orientation. The basin was filled with sediments during the Pliocene, over Miocene deposits. Borehole data show a depocenter located near its eastern margin with the Pliocene sediments forming a dissymmetrical synform controlled by the NNW-SSE Cidral border fault. The sedimentation culminates in Pleistoce...
Desafios ao planeamento dos territórios suburbanos
Cabral, João; Delgado Henriques, CristinaAs transformações nos processos e padrões de suburbanização em áreas metropolitanas têm sido objeto de estudo associadas aos desafios ao planeamento urbano. O objetivo principal do artigo é abordar os desafios ao planeamento dos territórios suburbanos respondendo a tendências globais em termos dos padrões de urbanização e a uma crise dos sistemas de regulação e de planeamento. A abordagem é apoiada nos debates ...
Iberia: insights from the Lower Mondego River terraces (central Portugal)
Martins, António; Cunha, Pedro; Gouveia, Margarida; Gomes, Alberto; Falguères, Christophe; Stokes, Martin; Voinchet, Pierre; Cabral, JoãoThe Lower Mondego Valley (LMV), located in the Western Iberian passive margin which is under compressive tectonic reactivation since ca. 80 Ma, is used for deciphering long-term landscape evolution during the Quaternary and the control played by active tectonics, eustasy and climate. The elaboration of a detailed geomorphological map allowed the establishment of the spatial and temporal distribution of the diff...
