Development of a predictive score to discriminate community acquired pneumonia ...
Barbosa-Martins, João; Mendonça, Joana; Carvalho, Nuno; Carvalho, Carolina; Sarmento, Helena; Soutinho, Gustavo; Coutinho, Camila; Cotter, JorgeBackground: A pneumonic infiltrate might hide an occult lung cancer (LC). This awareness depends on each clinician personal experience, turning definitive LC diagnosis challenging and possibly delayed. In this study we aimed to develop a clinical score to better identify those cases. Materials and Methods: We conducted a retrospective case–control study, including previously undiagnosed LC patients admitted in ...
Epidemiological and clinical aspects of Cutaneous and Mucosal Leishmaniases in ...
Rocha, Rafael; Conceição, Cláudia; Gonçalves, Luzia; Carvalho, Ana Cláudia; Maia, André; Martins, André; Carujo, António; Maio, António; Forra, CatarinaLeishmania infantum, a zoonotic vector-born parasite, is endemic in the Mediterranean region, presenting mostly as visceral (VL), but also as cutaneous (CL) and mucosal leishmaniasis (ML). This study aimed to describe the epidemiological and clinical aspects of the CL and ML cases diagnosed in mainland Portugal between 2010 and 2020. Collaboration was requested from every hospital of the Portuguese National Hea...
Clostridium difficile Severity and Outcome at a North of Portugal Healthcare Fa...
Barbosa-Martins, João; Mendonça, Joana; Carvalho, Carolina; Sarmento, Helena; Mota, Paula; Coutinho, Camila; Cotter, JorgeIntroduction: Clostridium difficile infection has been increasingly reported, with a significant healthcare burden and important morbimortality. This study aimed to characterize and describe the severity and outcomes of this event at a Portuguese hospital.Material and Methods: We conducted a retrospective analysis, by clinical record review, of all confirmed cases diagnosed in a hospital in the North of Portuga...
Design of a Multiband Full-Rate Ultra-Wideband Receiver in FPGA
Véstias, Mário; Cláudio de Campos Neto, Horácio; Sarmento, HelenaMultiBand OFDM (MB-OFDM) UWB [1] is a short-range promising wireless technology for high data rate communications up to 480 Mbps. In this paper, we have designed and implemented in an Virtex-6 FPGA an MB-OFDM UWB receiver for the highest data rate of 480 Mbps. To test the system, we have also implemented an MB-OFDM transmitter and an AWGN generator in VHDL and determined the bit error rates at the receiver runn...
A wireless sensors suite for Smart Grid applications
Grilo, António; Sarmento, Helena; Nunes, Mário; Gonçalves, José; Pereira, Paulo; Casaca, Augusto; Fortunato, CarlosThis paper presents a demonstrator of a Wireless Sensor and Actuator Network (WSAN) for Smart Grid applications, developed in the context of project WSAN4CIP. This WSAN is formed by WSAN nodes equipped with sensors and a wireless radio interface, which monitor key parameters of power grid equipments belonging to the Medium Voltage (MV) and Low Voltage (LV) segments. The measurements are reported to the SCADA sy...
FPGA implementation of IEEE 802.15.3C receiver
Véstias, Mário; Sarmento, HelenaThis paper presents the implementation of the OFDM demodulator and the Viterbi decoder, proposed as part of a wireless High Definition video receiver to be integrated in an FPGA. These blocks were implemented in a Xilinx Virtex-6 FPGA. The complete system was previously modeled and simulated using MATLAB/Simulink to extract importante hardware characteristics for the FPGA implementation.
Wilson’s disease: reggarding two cases
Drumond Freitas, Sara; Sarmento, Helena; Alves, Glória; Cotter, JorgeWilson’s disease is a rare disorder, with an autossomal recessive defect, caused by mutations in the ATP7B gene, a membrane-bound copper-transporting ATPase. Its deficiency results in the copper accumulation, preferably in the liver and brain.Patients often present with hepatic (from asymptomatic elevation of liver enzyme to severe hepatic failure) involvement and/or neuropsychiatric disease. The diagnosis is b...
Toxic hepatitis with interferon Beta-1a
Drumond Freitas, Sara; Sarmento, Helena; Alves, Glória; Cotter, JorgeInterferon beta-1a is one of the drugs, which is more frequently used among patients with multiple sclerosis. Some of the collateral effects of this drug are known, such as, injection site reactions, liver tests abnormalities, livedo reticularis, positivity to autoantibodies, haematological and neuropsychiatric abnormalities.The authors report a case of a patient with multiple sclerosis treated with interferon ...
