Laser printing of silver-based micro-wires in ZrO2 substrate for smart implant ...
Moura, Caroline Gomes; Faria, D.; Carvalho, Óscar Samuel Novais; Pereira, Rafael Santiago Floriani; Cerqueira, M. F.; Nascimento, R. M.Smart implants are endowed with functions of sensing, actuating and control to solve problems that may arise during their use. The assembly of these functions along the implant surface is still a challenge. However, with the advent of 3D printing, it is possible to print on implants’ surface, communication channels or micro-antennas or even sensoric/actuating areas. Hence, a positive impact on the long-term per...
Ti6Al4V laser surface preparation and functionalization using hydroxyapatite fo...
Faria, D.; Abreu, C. S.; Buciumeanu, Mihaela; Dourado, N.; Carvalho, Óscar Samuel Novais; Silva, F. S.; Miranda, G.This work presents a novel texture design for implants surface functionalization, through the creation of line-shaped textures on Ti6Al4V surfaces and subsequent sintering of hydroxyapatite (HAp) powder into the designated locations. HAp-rich locations were designed to avoid HAp detachment during insertion, thus guaranteeing an effective osseointegration. This process starts by creating textured lines using a N...
ENERWAT project: some preliminary results
Matos, C.; Cunha, A.; Pereira, F.; Gonçalves, A. Manuela; Silva, E.; Pereira, S.; Bentes, I.; Faria, D.; Briga-Sá, A.Water and energy are two linked important resources and its use efficient must be profoundly studied. On the other hand, it is believed that there are significant differences between the pattern of water and energy consumption in rural and urban areas, whose influencing factors require study too. Swveral research state a large difference in urban and rural household water consumption pattern. However, rural hou...

Matos, C.; Bentes, I.; Pereira, S.; Gonçalves, A. Manuela; Faria, D.; Briga-Sá, A.Rural and urban environments present significant differences between water and energy consumptions. It is important to know, in detail, which factors related to the consumption of these two resources are different in both environments, once that will be those important to manage and discuss in order to improve its use efficiency and sustainability. This research work involves a survey whose aim is to find the f...

Recém-Nascido de Há 20 Anos com Menos de 2001 Gramas: Sobrevivência e «Follow-Up»
Faria, D.; Agostinho, M.; Negrão, F.; Ramos, C.O recém-nascido (RN) de baixo peso é um grupo de risco em que, para além da sobrevivência, interessa saber a longo prazo as sequelas neurológicas. Com este objectivo, realizou-se uma análise retrospectiva da sobrevivência na alta do RN com peso nascimento igual ou inferior a 2000 gramas, internado na Unidade de Cuidados Especiais (UCERN) da Maternidade Bissaya Barreto, de Janeiro de 1973 a Dezembro de 1974. No ...
Outbreak of Clostridium difficile PCR ribotype 027-the recent experience of a r...
Oleastro, M.; Coelho, M.; Gião, M.; Coutinho, S.; Mota, S.; Santos, A.; Rodrigues, J.; Faria, D.Background: Clostridium difficile infection (CDI) is the leading cause of healthcare-associated diarrhea, and several outbreaks with increased severity and mortality have been reported. In this study we report a C. difficile PCR ribotype 027 outbreak in Portugal, aiming to contribute to a better knowledge of the epidemiology of this agent in Europe. Methods: Outbreak report with retrospective study of medical r...
Fungal Meningitis in an Immunocompetent Patient
Louro, R.; Ferreira, R.; Pinheiro, C.; Parada, H.; Faria, D.; Monteiro, E.Cryptococcal meningitis is a rare entity among immunocompetent hosts but, when it occurs, it is associated with significant morbidity and mortality. Clinical presen- tation as well as the course of the disease is usually subtle and indolent with headache and altered mental status. The authors present the case of a 59-year-old man, who sought medical help with a 2-week history of headaches accompanied by nausea ...

Monitorização do Consumo de Antibióticos nos Serviços de Cirurgia e de Ortopedi...
Caldeira, L.; Teixeira, I.; Vieira, I.; Batel-Marques, F.; Santiago, L.; Rodrigues, V.; Fonseca, A.; Varanda, J.; Bicó, A.; Vasconcelos, C.; Polónia, J.A monitorização do consumo de antimicrobianos é um instrumento de interesse indiscutível e tem merecido uma atenção particular nos últimos anos, devido às crescentes preocupações com a emergência de estirpes microbianas multi-resistentes. Os objectivos do presente estudo consistiram, por um lado, na monitorização do consumo e na avaliação do impacto económico da prescrição hospitalar de antimicrobianos, em serv...
