Community Urinary Tract Infections: Guideline Adjustment
Lopes Cunha, Carina; M. Costa, Andreia; João Brandão, Maria; Lopes, Hugo; Neves, Isabel; Alves, ValquíriaIntroduction: Urinary tract infections are very common in the community and are one of the most common reasons for antibiotic prescription. Our objective was to identify the most frequent microorganisms present in urine cultures in Primary Health Care, at a Local Health Unit and their sensitivity profile to some antibiotics.Methods: Observational and retrospective study based on bacteriological identification i...
Characterization of vancomycin-resistant Enterococcus faecium causing infection...
Antunes, Beatriz; Almeida-Santos, Ana C.; Read, Antónia; Alves, Valquíria; Novais, Carla; Peixe, Luísa; Freitas, Ana R.Background: Vancomycin-resistant Enterococcus faecium (VREfm) are leading nosocomial pathogens linked to high mortality rates and costs [1,2]. VREfm are also included in the WHO global priority list of antibiotic-resistant bacteria for which new antibiotics are urgently needed [3]. Their epidemiology is puzzling within Europe and VREfm data in Portuguese hospitals are lacking since the 2000s. Objective: We...
Epidemiology and discrimination of clinically relevant Enterobacter cloacae com...
Martins, Rita; Gonçalves, Ana Beatriz; Marques Silva, Luís; Castro, Ana Paula; Read, Maria Antónia; Alves, Valquíria; Peixe, Luísa; Novais, ÂngelaBackground: E. cloacae complex species are increasingly implicated in infections caused by multidrug-resistant bacteria, but their epidemiology is scarce due to the limitations of automated methods in accurate species identification (e.g. VITEK2/ MALDI–TOF MS) [1]. FT-IR is a promising quick, simple and low-cost alternative for bacterial discrimination [2]. Objective: We aim to assess the epidemiology of Entero...

Evidence for the dissemination to humans of Methicillin-Resistant Staphylococcu...
Bouchami, Ons; Fraqueza, M. J.; Faria, Nuno Alexandre; Alves, Valquíria; Lawal, Opeyemi Uwangbaoje; Lencastre, Herminia de; Miragaia, MariaLivestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) ST398 was recovered from infections in humans exposed to animals, raising public health concerns. However, contact with food producing chain as a means of transmission of LA-MRSA to humans remains poorly understood. We aimed to assess if pork production chain is a source of MRSA ST398 for human colonization and infection. MRSA from live ...
Pneumococcal Pneumonia and Influenza A Pneumonia: A Comparative Study
Fonseca, Sara; Barbosa, Ana; Melnikova, Zuzana; Silva, Cláudia; Silva, Sónia; Alves, Valquíria; Barreto, J. VascoIntroduction: Pneumonia is defined as an infection of the lungparenchyma. The most common overall pathogen is Streptococcuspneumoniae, however, influenza virus is also commonand is associated with severe disease. The viral etiology ofpneumonia is underdiagnosed. We analyzed and comparedthe clinical, laboratory and radiological data, severity at admissionand outcome of patients with influenza A pneumoniaand pneu...
Infeções Por Bactérias Multirresistentes em Idade Pediátrica: Estudo Retrospeti...
Abreu, Marlene; Leite, Joana; Portela, Alexandrina; Alves, Valquíria; Almeida, RuiIntrodução: As bactérias multirresistentes são responsáveis por uma importante morbimortalidade à escala mundial. Contudo, o seu impacto a nível pediátrico é pouco conhecido. O presente estudo pretendeu caracterizar as infeções por bactérias multirresistentes isoladas em amostras de doentes pediátricos de uma unidade hospitalar de nível I. Métodos: Estudo retrospetivo, descritivo e analítico dos casos de infeçõ...
Infecção Pulmonar por Adenovirus. Experiência da Unidade de Pneumologia Pediátrica
Costa, Teresa; Alves, Valquíria; Nunes, Teresa; Vaz, Luísa GuedesOs autores apresentam um estudo retrospectivo de infecção pulmonar por adenovirus, em crianças internadas no Departamento de Pediatria do H. S. João, durante um período de 6 anos, com o objectivo de avaliar a sua incidência, morbilidade e mortalidade. Os parâmetros analisados foram a distribuição por sexo, etária e sazonal, apresentação clínica, radiológica e laboratorial e evolução a doença. Das 40 crianças av...
