1. The segmentation of the left ventricle of the heart from ultrasound data using deep learning architectures and derivative-based search methods - Carneiro, G; Nascimento, J; Freitas, A
We present a new supervised learning model designed for the automatic segmentation of the left ventricle (LV) of the heart in ultrasound images. We address the following problems inherent to supervised learning models: 1) the need of a large set of training images; 2) robustness to imaging conditions not present in the training data; and 3) complex search process. The innovations of our approach reside in a formulation that decouples the rigid and nonrigid detections, deep learning methods that model the appearance of the LV, and efficient derivative-based search algorithms. The functionality of our approach is evaluated using a data...

2. Sepsis, meningitis and cerebral abscesses caused by Citrobacter koseri - Marecos, C; Ferreira, M; Ferreira, MM; Barroso, R
After a 36-week diamniotic dichorionic gestation, an infant was delivered by elective caesarean section due to growth restriction and altered diastolic flow in the umbilical artery. Birth weight was 2140 g. The patient was admitted for exclusive parenteral nutrition, with umbilical venous catheter placement. Sinus tachycardia and temperature instability with positive inflammatory markers occurred at 51 h. Penicillin and gentamicin were started, but 6 h later septic shock with disseminated intravascular coagulation was noted. Vancomycin and meropenem were started and penicillin suspended. Citrobacter koseri was isolated from blood culture. Generalised clonic convulsions occurred on day 4, and an electroencephalogram revealed...

5. Leprosy and rheumatoid arthritis: consequence or association? - Henriques, C; Lopéz, B; Mestre, T; Grima, B; Panarra, A; Riso, N
Leprosy or Hansen's disease is a chronic granulomatous infectious disease caused by Mycobacterium leprae with a high prevalence in some developing countries however, it is rarely seen in non-endemic regions. Arthritis has been described in all types of Hansen's disease. Chronic arthritis is known to exist even in paucibacillary forms, resolved or treated disease and in patients without reaction, suggesting a perpetuated inflammatory process. In these cases leprosy can mimic some autoimmune diseases such as rheumatoid arthritis. When a patient with a history of leprosy presents with a symmetric, distal, polyarthritis the diagnosis may not be linear. Possibly it is...

6. Non-tumor necrosis factor-based biologic therapies for rheumatoid arthritis: present, future, and insights into pathogenesis. - Paula, F; Alves, J
Therapeutic options for patients suffering from the more severe forms of spondyloarthritis have been rather limited in the last decades. There is now accumulating evidence that antitumor necrosis factor therapy is highly effective in spondyloarthritis, especially in ankylosing spondylitis and psoriatic arthritis. Based on the data recently published on more than 500 patients with ankylosing spondylitis and psoriatic arthritis, this treatment seems to be even more effective than in rheumatoid arthritis. The antitumor necrosis factor-alpha agents currently available, infliximab (Remicade), etanercept (Enbrel), and adalimumab (Humira), are approved for the treatment of rheumatoid arthritis in the United States and partly in...

7. Performance evaluation of a new fourth-generation HIV combination antigen-antibody assay - Mühlbacher, A; Schennach, H; van Helden, J; Hebell, T; Pantaleo, G; Bürgisser, P; Sousa, JG, et al.
Education and diagnostic tests capable of early detection represent our most effective means of preventing transmission of human immunodeficiency virus (HIV). The importance of early detection is underlined by studies demonstrating increased life expectancy following early initiation of antiviral treatment. The Elecsys(®) HIV combi PT assay is a fourth-generation antigen-antibody combination assay developed to allow earlier detection of seroconversion, and to have increased sensitivity and improved specificity. We aimed to determine how early the assay could detect infection compared with existing assays; whether all HIV variants could be detected; and the assay's specificity using samples from blood donors, routine specimens,...

8. Desarrollo de la autonomía de los jóvenes portadores de espina bífida: lo que dicen los jóvenes y sus padres/cuidadores - Caseiro, J; Gonçalves, T; Malheiro, MI
La Espina Bífida (EB) es una malformación congénita de la médula espinal, de acuerdo con el nivel de lesión de la médula espinal, estos niños presentan limitaciones de tipo ortopédico, urológico, motor y sensorial, que dificultan la adquisición de las habilidades necesarias para llevar a cabo sus actividades de la vida diaria (AVD) y la construcción de su autonomía. Este proceso está influenciado de forma positiva o negativa por el modo cómo los padres perciben sus necesidades. Así, los principales objetivos de este estudio fueron conocer la opinión de los jóvenes con Espina Bífida (EB) y de sus padres/cuidadores acerca...

9. Correlation of morphologic and pathologic features of the various tendon groups around the ankle: MR imaging investigation. - Cabral, P; Paulino, C; Takahashi, R; Clopton, P; Resnick, D
OBJECTIVE: To determine if a statistical association exists between abnormalities in one ankle tendon group (i.e., peroneal, medial flexor, or Achilles) and those in another. MATERIALS AND METHODS: A retrospective analysis of 1.5-T and 3-T MR ankle examinations in 100 patients conducted between November 1, 2011 and April 1, 2012 was performed. The cross-sectional areas and diameters of the ankle tendons-Achilles (ACH), peroneus brevis (PB) and longus (PL), tibialis posterior (TP), flexor digitorum longus (FDL), and flexor hallux longus (FHL)-were measured, and the results were correlated to determine any association with the presence of qualitative abnormalities (tenosynovitis, tendinosis, and tendon tearing). RESULTS:...

10. International recommendations for the assessment of autoantibodies to cellular antigens referred to as anti-nuclear antibodies. - Agmon-Levin, N; Agmon-Levin, J; Kallenberg, C; Sousa, MJ, et al.
Anti-nuclear antibodies (ANA) are fundamental for the diagnosis of autoimmune diseases, and have been determined by indirect immunofluorescence assay (IIFA) for decades. As the demand for ANA testing increased, alternative techniques were developed challenging the classic IIFA. These alternative platforms differ in their antigen profiles, sensitivity and specificity, raising uncertainties regarding standardisation and interpretation of incongruent results. Therefore, an international group of experts has created recommendations for ANA testing by different methods. Two groups of experts participated in this initiative. The European autoimmunity standardization initiative representing 15 European countries and the International Union of Immunologic Societies/World Health Organization/Arthritis Foundation/Centers for...

12. Papel da enfermagem no programa de reabilitação e reinserção social do doente cardiaco - Chambel, N

13. Erros de medicação: percepção dos enfermeiros sobre a ocorrência de erros de medicação numa UCI - Pereira, E; Fernandes, P; Semião, S
Um doente internado num hospital, pode receber até dezoito doses de medicação por dia e um enfermeiro pode administrar até cinquenta medicamentos num turno, estando assim no centro da possibilidade do erro (1). Embora o Hospital Prof. Dr. Fernando Fonseca EPE (HFF) disponha de um sistema de notificação de ocorrências que permite a notificação de qualquer tipo de ocorrências, de forma anónima ou não, a realidade é que este é pouco utilizado pelos profissionais do serviço. Ora isto levanta-nos várias questões. Se não conhecemos as falhas como poderemos preveni-las? Porque não são reportados os erros de medicação? Por este motivo, elaborou-se um...
