SUSCEPTIBILITY TEST FOR FUNGI: CLINICAL AND LABORATORIAL CORRELATIONS IN MEDICAL MYCOLOGY

SUMMARYDuring recent decades, antifungal susceptibility testing has become standardized and nowadays has the same role of the antibacterial susceptibility testing in microbiology laboratories. American and European standards have been developed, as well as equivalent commercial systems which are more appropriate for clinical laboratories. The detection of resistant strains by means of these systems has allowed the study and understanding of the molecular basis and the mechanisms of resistance of fungal species to antifungal agents. In addition, many studies on the correlation of in vitro results with the outcome of patients have been performed, reaching the conclusion that infections caused by resistant strains have worse outcome than those caused by susceptible fungal isolates. These studies have allowed the development of interpretative breakpoints for Candida spp. and Aspergillus spp., the most frequent agents of fungal infections in the world. In summary, antifungal susceptibility tests have become essential tools to guide the treatment of fungal diseases, to know the local and global disease epidemiology, and to identify resistance to antifungals.

Psychiatric and Psychosocial Predictors of Medical Outcome After Liver Transplantation: a Prospective, Single-Center Study

OBJECTIVE: Recognizing the potential impact of psychiatric and psychosocial factors on liver transplant patient outcomes is essential to apply special follow-up for more vulnerable patients. The aim of this article was to investigate the psychiatric and psychosocial factors predicted medical outcomes of liver transplanted patients. METHODS: We studied 150 consecutive transplant candidates, attending our outpatient transplantation clinic, including 84 who had been grafted 11 of whom died and 3 retransplanted. RESULTS: We observed that active coping was an important predictor of length of stay after liver transplantation. Neuroticism and social support were important predictors of mortality after liver transplantation. CONCLUSION: It may be useful to identify patients with low scores for active coping and for social support and high scores for neuroticism to design special modes of follow-up to improve their medical outcomes.

Dispositivos médicos para diagnóstico in vitro : impacto operacional, clínico e económico da sua utilização em instituições de saúde

RESUMO - Introdução: Os dispositivos médicos para diagnóstico in vitro (DMDIV) são testes de diagnóstico rápido que podem ser realizados em diversos contextos, seja na enfermaria, no departamento de urgência, no bloco operatório, no consultório médico, centros de enfermagem, farmácias, lares de terceira idade ou até na própria residência, uma vez que a sua utilização não requer formação especializada em técnicas de laboratório. Os DMDIV têm inúmeras finalidades: triagem de utentes, diagnóstico de situações agudas, monitorização de fármacos ou acompanhamento de doenças crónicas. Objectivos: conhecer as potenciais implicações operacionais, clínicas e económicas da implementação generalizada de DMDIV em instituições de saúde da região de Lisboa e Vale do Tejo, bem como conhecer o nível de utilização e opinião sobre DMDIV de médicos e enfermeiros da região de saúde de Lisboa e Vale do Tejo. Metodologia: foi realizado um estudo observacional, analítico e transversal. Como instrumento de recolha de dados, foi aplicado um questionário a uma amostra de conveniência constituída por médicos e enfermeiros a exercer funções em instituições hospitalares públicas e privadas e em instituições de cuidados de saúde primários da região de saúde de Lisboa e Vale do Tejo. Conclusão: a utilização de DMDIV permite diminuir o tempo de resposta do resultado analítico, o que se traduz numa maior rapidez do diagnóstico e numa intervenção clínica mais célere, com impacto ao nível da redução do número de admissões desnecessárias, do tempo de internamento e do número de consultas médicas, com a consequente redução do consumo de recursos hospitalares. Na região de saúde de Lisboa e Vale do Tejo, um número significativo de instituições de saúde disponibiliza este tipo de equipamentos portáteis que, de uma forma geral, têm uma boa aceitação por parte dos profissionais de saúde.

Improvisation in tightly controlled work environments: The case of medical practice

We present a qualitative analysis of organizational improvisation and provide a preliminary insight into the following question: how is improvisation present in tightly controlled work environments? We conducted in situ observations of, and interviews with, several emergency medical teams and complemented this information with statistical and media data. Using grounded theory, we developed four propositions that were arranged into a model that allowed the identification of two use levels of established routines: (1) the visible side that accommodates contextual requirements, and (2) the improvisational side that provides a response to activity characteristics. This dual process is related to the existence of pressures that operate at the institutional level with practical needs emerging from the operational domain. In contrast with most of the literature, this study reveals that the presence of a broad procedural organizational memory does not restrict improvisation but enables a bureaucratic system to produce flexible improvised performance.

Parasitoids of Ophyra aenescens (Wiedemann) (Diptera: Muscidae): fly of medical-sanitary importance collected in State of Goiás, Brazil

The objective of the study was to report the first occurrence of the parasitoid Brachymeria podagrica in pupae of Ophyra aenescens, a fly of medical-sanitary importance. Human feces was used as bait to collect the insects. In the study 20 pupae of Ophyra aenescens (Wiedemann) (Diptera: Muscidae) were obtained, of which 20% of the total yielded the parasitoid Brachymeria podagrica (Hymenoptera: Chalcididae).
