Caracterização das quedas de pacientes segundo notificação em boletins de eventos adversos

Este estudo foi desenvolvido com o objetivo de caracterizar as quedas de pacientes internados ocorridas em hospital terciário. Foram analisados 826 Boletins de Notificação de Eventos Adversos, de um período de 30 meses, que registraram 0,30 quedas por 1000 pacientes/dia. Quedas do leito foram mais frequentes (55%), com maior prevalência na enfermaria de neurologia. Maior frequência de quedas foi verificada no período noturno (63,7%), nos primeiros cinco dias da admissão (61,7%), nos pacientes de sexo masculino (57,5%) e na faixa etária maior de 60 anos (50%). Nos casos de quedas do leito, os diagnósticos relacionaram-se a doenças infecciosas e parasitárias (18,2%), doenças do sistema nervoso (18,2%) e doenças do aparelho circulatório (13,7%). Nas quedas da própria altura, os diagnósticos relacionaram-se a neoplasias (19,4%) e doenças do aparelho geniturinário (16,1%). A caracterização desses eventos adversos auxilia no reconhecimento dos grupos de maior risco e na elaboração de propostas preventivas.

Combined effect of linezolid and N-acetylcysteine against Staphylococcus epidermidis biofilms

Introduction: Staphylococcus epidermidis is an organism commonly associated with infections caused by biofilms. Biofilms are less sensible to antibiotics and therefore are more difficult to eradicate. Linezolid and N-acetylcysteine (NAC), have demonstrated to be active against gram-positive microorganisms. Therefore and since linezolid and NAC have different modes of action, the main objective of this work was to investigate the single and synergistic effect of linezolid and NAC against S. epidermidis biofilms. Methods: This work reports the in vitro effect of linezolid and NAC against S. epidermidis biofilms, treated with MIC (4 mg ml-1) and 10×MIC of NAC, and MIC (1 μg ml-1) and peak serum concentration (PS = 18 μg ml-1) of linezolid alone and in combination. After exposure of S. epidermidis biofilms to linezolid and/or NAC for 24 h, several biofilm parameters were evaluated, namely the number of cultivable cells [colony forming unit (CFU) enumeration], total biofilm biomass and cellular activity. Results: When tested alone, NAC at 10×MIC was the most effective agent against S. epidermidis biofilms. However, the combination linezolid (MIC) + NAC (10×MIC) showed a synergistic effect and was the most biocidal treatment tested, promoting a 5 log reduction in the number of biofilm viable cells. Conclusion: This combination seems to be a potential candidate to combat infections caused by S. epidermidis biofilms, namely as a catheter lock solution therapy. © 2012 Elsevier España, S.L.

Evaluación de los impactos del cambio climático sobre la salud: economía del cambio climático en la Argentina

Mientras que los países desarrollados presentan un 2% de su población infectada con parásitos o enfermedades infecciosas, los países en desarrollo alcanzan el 40%. Esto está asociado a las diferencias socioeconómicas reflejadas en la nutrición, sanidad, calidad de viviendas, condiciones de trabajo y servicios de salud. Por este motivo, el efecto del cambio climático sobre la salud en estos países debe centrarse en estas convalecencias. Argentina se encuentra en el límite sur de la distribución del dengue y la malaria en América del Sur, y es por ello que el estudio del riesgo de estas enfermedades frente a cambios climáticos es de suma importancia.

Speech-language therapy for treatment of dysphagia and dysphonia in systemic granulomatous diseases: granulomatous diseases: dysphagia and dysphonia treatments

The granulomatous lesions are frequently founded in infectious diseases and can involve the larynx and pharynx and can cause varying degrees of dysphonia and dysphagia. There is still no systematic review that analyzes effectiveness of speech therapy in systemic granulomatous diseases. Research strategy: A systematic review was performed according to Cochrane guideline considering the inclusion of RCTs and quasi-RCTs about the effectiveness of speech-language therapy to treat dysphagia and dysphonia symptoms in systemic granulomatous diseases of the larynx and pharynx. Selection criteria: The outcome planned to be measured in this review were: swallowing impairment, frequency of chest infections and voice and swallowing symptoms. Data analysis: We identified 1,140 citations from all electronic databases. After an initial shift we only selected 9 titles to be retrieved in full-text. After full reading, there was no RCT found in this review and therefore, we only described the existing 2 case series studies. Results: There were no randomized controlled trials found in the literature. Therefore, two studies were selected to be included only for narratively analysis as they were case series. Conclusion: There is no evidence from high quality studies about the effectiveness of speech-language therapy in patients with granulomatous diseases of the larynx and pharynx. The investigators could rely in the outcomes suggested in this review to design their own clinical trials.

Microbiota fúngica de passeriformes de cativeiros da Região Noroeste do Estado de São Paulo

Birds are hosts for a rich fungal microbiota which can act as potent pathogens for humans and other species of animals, causing thereby serious public health problems. The objective of this study was to evaluate the participation of birds kept in containers in the epidemiology of infectious diseases such as cryptococcosis and aspergillosis, thus verifying the maintenance and spread of pathogens in the environment. 36 samples of excretas of passeriformes were collected and were cultivated in Sabouraud Dextrose Agar 4% at room temperature and 37°C. The isolated fungal colonies were classified according to their morphological and staining characteristics. Subsequently, those in yeast form were peaked in Niger Agar, incubated at 30°C. In one sample showed growth of more than one type of colony and there was verified the presence of 25.0% of Penicillium spp., 19.4% of Trichosporon spp., 13.9% of C. gattii, 11.1% of C. neoformans, 11.1% of Candida spp., 8.3% of Rhizomucor spp., 8.3% of Aspergillus spp., 2.8% of Nigrospora spp. and 2,8% of Geotrichum spp. It can be conluded by the expost that birds shed continuously pathogenic microorganisms in their feces acting in definitive form in the infectious diseases ecoepidemiology.

Aggregatibacter actinomycetemcomitans em pacientes com síndrome de down: influência da condição periodontal e higiene bucal

Patients with Down syndrome have varying degrees of mental retardation, physical and motor, and apparently are more susceptible to infectious diseases. Thus, the present study aimed to evaluate the occurrence of Aggregatibacter actinomycetemcomitans in saliva and subgingival biofilms and above of children and adolescents with Down syndrome and analyze the influence of diet, socioeconomic and cultural factors and periodontal condition. After assessing the socio-economic and behavioral, were collected clinical specimens, which were transported to the laboratory of Microbiology and Immunology FOA-UNESP for detection of microorganisms by molecular method and periodontal conditions were evaluated according to the Periodontal Screening Index and Recording. The control group consisted of individuals without the syndrome. The results were analyzed by chi-square test for proportion analysis of variables with three or more categories, or the Mann-Whitney test. The data analysis of this study showed that the occurrence of A. actinomycetemcomitans ranged from 0.0% to 25.0%, both in the group of patients with Down syndrome, as for the control group and this was not affected by socioeconomic characteristics of the target population, either by oral hygiene standards
