Neonatal lupus erythematosus: A narrative review
Marques,Ana Raquel; Rocha,Gustavo; Soares,Paulo; Rodrigues,Mariana; Pimenta,JoanaAbstract Introduction: Neonatal lupus erythematosus (NLE) is characterized by the transplacental passage of maternal antibodies, mainly anti-Sjogren’s syndrome A/Ro (anti-SSA/Ro) and anti-Sjogren’s syndrome B/La (anti-SSB/La), which bind to the developing fetal tissues. Seropositive mothers may have a diagnosed disease, such as Sjögren’s syndrome, systemic lupus erythematosus, or undifferentiated connective tis...
Titanium-Niobium (Ti-xNb) Alloys with High Nb Amounts for Applications in Bioma...
Pereira,Bruno Leandro; Lepienski,Carlos Maurício; Seba,Viviane; Hobold,Guibert; Soares,Paulo; Chee,Bor Shin; Kuroda,Pedro Akira BazagliaThe present study produced binary titanium-niobium alloys Ti-xNb with high niobium percentage (x = 50, 80 e 90 wt.%) aiming to apply it as a base material in osseous implant devices. The produced TiNb alloys presented a cubic crystalline phase, lower corrosion rate than titanium, lower elastic modulus values, and superior cellular viability than titanium and niobium. The Ti50Nb alloy among all analyzed metallic...

e Monteiro,Eunice Vieira; Paiva,Cláudia; Soares,PauloAbstract Authors present a case report of a female patient, with 38-years-old, admitted with alithiasic acute pancreatitis. During the hospitalization on day 6 she referred migration of the pain to the lower right quadrant and had pain in decompression; she underwent a computed tomography scan that was compatible with acute appendicitis. She was admitted to the operating room and laparoscopic appendectomy was p...
Effect of thermal aging conditions on the corrosion properties and hardness of ...
May,José Eduardo; Souza,Carlos Alberto Caldas de; Nascente,Pedro Augusto de Paula; Soares,Paulo; Lepienski,Carlos Mauricio; Kuri,Sebastião EliasThe corrosion properties of a 22.5 wt. (%) Cr duplex stainless steel were investigated after long-term aging of 3000, 5000 and 7000 hours at 300 and 400 ºC. The corrosion resistance was measured based on mass loss in a FeCl3 10 wt. (%) solution and electrochemical measurements in a 0.1 M H2SO4 solution. The results indicate that the corrosion resistance decreased steadily up to 5000 hours of aging. However, the...
Derrames pleurais parapneumónicos em pediatria: Experiência num hospital centra...
Soares,Paulo; Barreira,João; Pissarra,Susana; Nunes,Teresa; Azevedo,Inês; Vaz,LuísaIntrodução: Os derrames pleurais podem complicar as pneumonias na população pediátrica. Assumem especial importância pelas implicações na duração do internamento, geralmente prolongado, e pela morbilidade associada. Objectivos: Caracterizar uma população de doentes com pneumonia complicada de derrame; determinar os possíveis factores de prognóstico a partir de dados clínicos, radiológicos e analíticos na admiss...
