Acute Porphyria Screening Protocol in the Emergency Department: A Strategy for ...

Acute porphyrias are a group of rare metabolic diseases, arise from defects in the heme biosynthesis pathway. These conditions are clinically characterized by acute neurovisceral attacks, chronic symptoms, and long-term complications. Given the non-specific presentation and the typically low index of clinical suspicion, diagnostic delays are recurrent and result in significant preventable morbimortality. To add...

Environmental change in SW Portugal during the last 3900 years BP: an ostracoda...

Ostracod, geochemical, mineralogical, and sedimentological proxies from a sediment core collected off Sagres (southwestern Portugal) were used to reconstruct Holocene environmental and hydrodynamic changes. Reduced variability of geochemical elements between ~4000 and ~1290 calibrated years before present suggests relatively stable conditions, regularly disturbed by higher-energy events. At ~1290 cal yrs BP, a ...

ST-Segment Elevation – Where’s the Myocardial Infarction?

ST-Segment Elevation – Where’s the Myocardial Infarction? Nuno Magalhães, Rui Filipe Gomes, Ana Raquel Gomes, Mariana Alves, Anabela Oliveira Medicina Interna, ULS Santa Maria, Lisboa Portugal In the emergency department (ED), ST-segment elevation typically prompts immediate investigation for suspected acute myocardial infarction (AMI). However, it is essential to recognize that not all ST-segment changes corre...

Relatório anual sobre o Tratamento de doenças lisossomais de sobrecarga, referente às atividades desenvolvidas pela respetiva Comissão Coordenadora em 2021. As Doenças Lisossomais de Sobrecarga (DLS) constituem um grupo de patologias raras, progressivas, com elevada morbilidade, que engloba, atualmente, mais de 60 patologias, cuja apresentação clínica é extremamente variável, podendo ir desde doença neurológica...

Portuguese Consensus on Acute Porphyrias: Diagnosis, Treatment, Monitoring and ...

Acute porphyrias are a group of rare genetic metabolic disorders, caused by a defect in one of the enzymes involved in the heme biosynthesis, which results in an abnormally high accumulation of toxic intermediates. Acute porphyrias are characterized by potentially life-threatening attacks and, for some patients, by chronic manifestations that negatively impact daily functioning and quality of life. Clinical man...

New physical and biological evidence of lateral transport affecting dinoflagell...

ntroduction The production of resting cysts is a key dispersal and survival strategy of many dinoflagellate species. However, little is known about the role of suspended cysts in the benthic nepheloid layer (BNL) in the initiation and decline of planktonic populations.Methods In September 2019, sampling of the dinoflagellate cyst community at different water depths in the water column and in the bottom sediment...

Modeling LoRa Communications in Estuaries for IoT Environmental Monitoring Systems

Low-power wide-area networks are extending beyond the conventional terrestrial domain. Coastal zones, rivers, wetlands, among others, are nowadays common deployment settings for Internet-of-Things nodes where communication technologies such as LoRa are becoming popular. In this article, we investigate large-scale fading dynamics of LoRa line-of-sight links deployed over an estuary with characteristic intertidal...

Reconfiguration of a Multi-purpose Central Emergence Service in the Face of the...

Multi-Hazard WebGIS Platform for Coastal Regions

The combined action of waves, surges and tides can cause flooding, erosion and dune and structure overtopping in many coastal regions. Addressing emergency and risk management in these areas require a combination of targeted campaigns and real-time data that measure all phenomena at stake and can be used to develop comprehensive monitoring platforms. These monitoring platforms can support the development of pre...
