Knowledge and attitudes of health care workers from intensive care units regarding nosocomial transmission of influenza: a study on the immediate pre-pandemic period

The transmission of influenza in health care settings is a major threat to patients, especially those with severe diseases. The attitude of health care workers (HCWs) may influence the transmission of countless infections. The current study aimed to quantify knowledge and identify attitudes of HCWs involved in intensive care units (ICUs) regarding the risk of nosocomial influenza transmission. A questionnaire was applied through interviews to HCWs who worked in one of the five ICUs from a teaching hospital. Questions about influenza were deliberately dispersed among others that assessed several infectious agents. Forty-two HCWs were interviewed: nine physicians, ten nurses and 23 nursing technicians or auxiliaries. Among the 42 HCWs, 98% were aware of the potential transmission of influenza virus in the ICUs, but only 31% would indicate droplet precautions for patients with suspected infection. Moreover, only 31% of them had been vaccinated against influenza in the last campaign (2008). Nursing technicians or auxiliaries were more likely to have been vaccinated, both by univariate and multivariable analysis. When asked about absenteeism, only 10% of the study subjects stated that they would not go to work if they had an influenza-like illness. Those findings suggest that, in non-pandemic periods, influenza control in hospitals requires strategies that combine continuous education with changes in organizational culture.

Occurrence of sensitivity during at-home and in-office tooth bleaching therapies with or without use of light sources

The aim of this study was to evaluate the effect of tooth bleaching with 10% carbamide peroxide (CP) or 35% hydrogen peroxide (HP), with or without quartz-tungsten-halogen light or hybrid source LED/infrared laser exposition on the occurrence duration, intensity and location of tooth sensitivity Forty patients were selected and randomly divided into four groups: GI--home bleaching with CP for 4 hours a day, over the course of 3 weeks; GII--three sessions of HP with three 10-minute applications at each session and no light source; GIII--the same procedure as GII with quartz-tungsten-halogen light irradiation; GIV--the same procedure as GII with LED/laser light irradiation. The evaluation included an appointment with each patient before and after each HP bleaching session or each weekly CP bleaching and 7, 30 and 180 days after the end of treatment. The Kruskal-Wallis test revealed that the duration and intensity of post-treatment sensitivity were significantly higher for HP than for CP (p< 0.05), and symptoms were located predominantly in anterior teeth. All bleaching methods generated sensitivity, which was more frequent in anterior teeth. However, treatment with CP generated lower sensitivity than treatment with HP independently of the light sources.

Between freedom and reclusion: Social support as a quality-of-life component in the family caregiver-dependent person binomial

This is a qualitative study which uses Grounded Theory as its methodological framework and Symbolic Interactionism as a theoretical base to understand the experience of family caregivers for Cerebrovascular Accident (CVA) patients with regard to social support during their rehabilitation process at home. The components (themes and categories) of the phenomenon assuming home care and specifically the themes assuming care with support and assuming care without support were inter-related for the purpose of comparison and analysis, in order to apprehend how the interaction between them occurred, It was observed that, in addition to the recovery of the patient's autonomy, social support is one of the intervenient components in the quality of life for the family caregiver-disabled person binomial, particularly with respect to the caregiver's freedom to resume his/her life plan.

Condições de trabalho e transtornos mentais comuns em trabalhadores da rede básica de saúde de Botucatu (SP)

Os transtornos mentais comuns (TMC) apresentam elevada prevalência em populações gerais e de trabalhadores, com consequências individuais e sociais importantes. Este estudo, transversal e descritivo, explora a relação entre demandas psicológicas, grau de controle e presença de suporte social no trabalho e prevalência de TMC em trabalhadores da rede básica de saúde de Botucatu (SP). A coleta de dados foi feita por meio de questionário autoaplicável, não identificado, com destaque para itens relativos à demanda-controle-suporte e presença de TMC (Self Reporting Questionnaire, SRQ-20). As informações foram inseridas em banco de dados construído com Excel/Office XP 2003 e a análise estatística, efetuada com o programa SAS. Constatou-se que 42,6% dos trabalhadores apresentavam TMC. A observação de associação - alta prevalência de TMC com elevado desgaste (classificação de Karasek) e baixa prevalência de TMC com baixo desgaste - indica que, no município estudado, as condições de trabalho na atenção básica constituem fator contributivo não negligenciável ao adoecimento dos trabalhadores. Revela-se a necessidade de intervenções direcionadas ao cuidado aos trabalhadores, melhoria das condições de trabalho e aumento do suporte social no trabalho.

A eficácia da reabilitação em disfagia orofaríngea

TEMA: eficácia da reabilitação em disfagia orofaríngea. A atuação fonoaudiológica com disfagia orofaríngea em nosso País alcançou proporções significativas e merece neste momento atenção para que esta atuação esteja baseada em evidências científicas. As técnicas terapêuticas e a eficácia da reabilitação em disfagia orofaríngea têm sido estudadas desde a década de 70, alcançando seu ápice na década de 80 e 90. Poucos estudos têm relatado a eficácia da reabilitação em disfagia orofaríngea, sendo mais freqüente aqueles que têm se preocupado em provar os efeitos da técnica terapêutica na dinâmica da deglutição. No Brasil, as pesquisas em disfagia orofaríngea têm valorizado os procedimentos de avaliação, sendo poucos os trabalhos que tratam da reabilitação. OBJETIVO: apresentar uma análise crítica sobre a eficácia da reabilitação em disfagia orofaríngea. CONCLUSÃO: este artigo de revisão aponta que estudos não randomizados têm comprometido os resultados, uma vez que a casuística das pesquisas têm utilizado amostras muito heterogêneas, que incluem disfagias orofaríngeas mecânicas e neurogênicas ocasionadas por distintas etiologias. Além disto, os programas terapêuticos empregados são pouco descritivos comprometendo a reprodução por parte de outros pesquisadores. Tais achados sugerem a necessidade de estudos mais randomizados, talvez inicialmente por meio de estudos de casos que possam excluir as variáveis do controle da eficácia terapêutica. Outra sugestão seria empregar, assim como as pesquisas atuais têm proposto, escalas que possam medir o impacto do treinamento de deglutição nas condições nutricionais e pulmonares do indivíduo disfágico. Uma importante área da pesquisa, relacionada ao controle da eficiência e eficácia terapêutica, está nos estudos que objetivam estabelecer o grau de redução de custos hospitalares e em empresas de home care, mediante a atuação do fonoaudiólogo com a disfagia orofaríngea.

Alergia ao látex e a frutas em profissionais da área da saúde

INTRODUÇÃO: A alergia ao látex tornou-se um risco crescente aos indivíduos expostos, como os profissionais da área da saúde, tendo como agravo a associação com hipersensibilidade a vários alimentos, especialmente frutas. OBJETIVO: Avaliar a freqüência de sensibilização ao látex e a frutas em profissionais da área da saúde. MÉTODOS: Foram avaliados 53 profissionais da saúde, 81,9% do sexo feminino, aplicando-se questionário alergológico e testes cutâneos por puntura para alérgenos inaláveis, do látex e de frutas (mamão papaia, kiwi, abacate, banana, figo, tomate, noz). RESULTADOS: Dos 53 indivíduos estudados, 15 (28,5%) eram alérgicos ao látex. A sensibilidade a frutas foi diagnosticada em 14 (26,4%), dos quais 10 (18,8%) apresentavam teste por puntura positivo para o látex; as frutas alergênicas mais freqüentes foram papaia (80,0%), kiwi (60,0%) e abacate (50,0%). CONCLUSÃO: Estes achados demonstram a existência da alergia látex-fruta, como descrito na literatura, sendo de suma importância uma avaliação in vivo em profissionais da área de saúde, caracterizados como potencial grupo de risco.

An open-label, comparative study of the efficacy and safety of once-daily dose of enoxaparin versus unfractionated heparin in the treatment of proximal lower limb deep-vein thrombosis

Background: Treatment of deep-vein thrombosis (DVT) with a once-daily regimen of enoxaparin, rather than a continuous infusion of unfractionated heparin (UFH) is more convenient and allows for home care in some patients. This study was designed to compare the efficacy and safety of these two regimens for the treatment of patients with proximal lower limb DVT. Methods: 201 patients with proximal lower limb DVT from 13 centers in Brazil were randomized in an open manner to receive either enoxaparin [1.5 mg/kg subcutaneous (s.c.) OD] or intravenous (i.v.) UFH (adjusted to aPTT 1.5-2.5 times control) for 5-10 days. All patients also received warfarin (INR 2-3) for at least 3 months. The primary efficacy endpoint Was recurrent DVT (confirmed by venography or ultrasonography), and safety endpoints included bleeding and serious adverse events. The rate of pulmonary embolism (PE) was also collected. Hospitalization was at the physician's discretion. Results: Baseline patient characteristics were comparable between groups. The duration of hospital stay was significantly shorter with enoxaparin than with UFH (3 versus 7 days). In addition, 36% of patients receiving enoxaparin did not need to be hospitalized, whereas all of the patients receiving UFH were! hospitalized. The treatment duration was slightly longer with enoxaparin (8 versus 7 days). There was a nonsignificant trend toward a reduction in the rate of recurrent DVT with enoxaparin versus UFH, and similar safety. Conclusions: A once-daily regimen of enoxaparin 1.5 mg/kg subcutaneous is at least as effective and safe as conventional treatment with a continuous intravenous infusion of UFH. However, the once daily enoxaparin regimen is easier to administer (subcutaneous versus intravenous), does not require aPTT monitoring, and leads to both a reduced number of hospital admissions and an average 4-day-shorter hospital stay.

Viability of Streptococcus mutans on transparent and opaque toothbrushes.

PURPOSE: The objective of this study was to evaluate the viability of the microorganism Streptococcus mutans on toothbrushes made of opaque and transparent materials. METHODS: Twenty-eight toothbrushes (14 opaque and 14 transparent) were inoculated in tubes with brain heart infusion (BHI) broth of a standard strain of S. mutans and incubated in candle jars at 37 degrees C for 24 hours. Both the opaque and transparent toothbrushes were removed at T = 0 h (control); T = 0.5 h; T = 1 h; T = 2 h; T = 4 h; T = 8 h; and T = 24 h. Individual toothbrushes were subjected to agitation in a saline solution and samples of the solution were diluted and inoculated in Bacitracin Sucrose Agar--SB-20. RESULTS: After half an hour (T2) there was a significant decrease in the number of microorganisms on the transparent and opaque toothbrushes, respectively 6.0 x 10(5) and 9.4 x 10(5), when compared to the control. After the T3 = 1 hour, T4 = 2 hours, T5 = 4 h, the number of microorganisms decreased from 4.1 x 10(5); 2.1 x 10(5); 1.4 x 10(5); and 9.2 x 10(5); 5.7 x 10(5); 1.2 x 10(5) to zero (0.0) in T6 = 8 h, respectively on the transparent and opaque toothbrushes. The reduction in viable microorganisms was more obvious with the transparent toothbrushes, although the number of viable microorganisms was not significantly different for the two types of toothbrushes at the end of the experiment, T5 = 1.4 x 10(5) (transparent) and T5 = 1.2 x 10(5) (opaque). CONCLUSIONS: With both opaque and transparent toothbrushes, the number of microorganisms decreased with time. A reduction in the number of microorganisms on the transparent toothbrushes was observed following inoculation and incubation. This suggests the transparent toothbrushes inhibit the viability of the S. mutans.

Comparison of manual versus sonic and ultrasonic toothbrushes: a review.

PURPOSE: This review of the literature intends to evaluate the effect of brushes with high frequency motion when compared with manual toothbrushes regarding the indices of plaque and gingival bleeding. METHODS: Patients presenting gingivitis and/or chronic periodontitis were evaluated in addition to patients having osseointegrated implants and fixed orthodontic appliances. Pertinent literature was reviewed to select articles according to previously defined inclusion criteria. RESULTS: In the assessed studies results showed significant decreases in plaque and gingival indices by utilization of both types of brushes. However, in the selected studies where sonic brushes were tested in orthodontic and dental implant patients there was a more significant decrease in the indices. Furthermore, there was no indication of gingival recession attributed to product use. CONCLUSION: Future studies with a more homogeneous methodology and better experiment designs will be needed.
