Is There Sufficient Training of Health Care Staff on Noise Reduction in Neonatal Intensive Care Units? a Pilot Study From NeoNoise Project

Evidence indicates that exposure to high levels of noise adversely affects human health, and these effects are dependent upon various factors. In hospitals, there are many sources of noise, and high levels exert an impact on patients and staff, increasing both recovery time and stress, respectively. The goal of this pilot study was to develop, implement and evaluate the effectiveness of a training program (TP) on noise reduction in a Neonatal Intensive Care Units (NICU) by comparing the noise levels before and after the implementation of the program. A total of 79 health professionals participated in the study. The measurements of sound pressure levels took into account the layout of the unit and location of the main sources of noise. General results indicated that LAeq levels before implementation of the training program were often excessive, ranging from 48.7 ± 2.94 dBA to 71.7 ± 4.74 dBA, exceeding international guidelines. Similarly following implementation of the training program noise levels remained unchanged (54.5 ± 0.49 dBA to 63.9 ± 4.37 dBA), despite a decrease in some locations. There was no significant difference before and after the implementation of TP. However a significant difference was found for Lp, Cpeak, before and after training staff, suggesting greater care by healthcare professionals performing their tasks. Even recognizing that a TP is quite important to change behaviors, this needs to be considered in a broader context to effectively control noise in the NICU.

Impacto das medidas de conservação de energia em projeto na redução da intensidade de utilização de matérias-primas na construção de um edifício

O presente trabalho pretende mostrar que a aplicação de medidas de conservação de energia (MCE) pode representar uma redução da intensidade de utilização de matérias-primas na construção de um edifício. Mais concretamente, pode representar uma redução da utilização de materiais e equipamentos, e como consequência, uma redução no esforço económico ao primeiro investimento. Podendo posteriormente representar uma redução na utilização de energia durante o período de funcionamento do edifício. A aplicação de MCE no sector da construção tem vindo a ser uma prática corrente nos novos edifícios e edifícios sujeitos a grandes intervenções de reabilitação. Esta prática deve-se à obrigatoriedade de cumprimento de requisitos regulamentares aplicados à otimização do desempenho energético dos edifícios e dos seus sistemas técnicos, nomeadamente, o RCCTE e o RSECE, entretanto revogados pelo REH e pelo RECS, respetivamente. A implementação de MCE apresenta, na maioria dos casos, benefícios económicos para o promotor do edifício, uma vez que se traduz muitas vezes, na otimização do dimensionamento dos sistemas de Aquecimento, Ventilação e Ar Condicionado (AVAC). Esta otimização permite reduzir os custos associados ao primeiro investimento, bem como na utilização de energia por parte do utilizador, logo na redução dos custos de exploração. No entanto, a falta de quantificação dos impactos do dimensionamento dos sistemas AVAC, da redução de utilização de energia e da análise do custo-benefício da sua aplicação pode condicionar o interesse na sua implementação. Neste contexto, surge a presente dissertação, por iniciativa do Instituto Soldadura e Qualidade (ISQ), aplicado a um caso prático de um edifício já construído e propriedade daquela empresa. Com este trabalho pretende-se avaliar o contributo efetivo das MCE implementadas na fase de projeto e na fase de construção, quer na otimização da dimensão de sistemas e equipamentos AVAC, por via da redução das necessidades energéticas, quer na redução de utilização de energia, permitindo, de seguida, uma avaliação custo-benefício.Na base do caso de estudo está o ECOTERMOLAB, o edifício acima referido, adquirido pelo ISQ para instalação de um laboratório de formação, investigação e desenvolvimento na área da energia. Após aquisição pelo ISQ, o edifício sofreu várias alterações/beneficiações, entre as quais a implementação de MCE, tais como, a aplicação de isolamento térmico na envolvente opaca (paredes, pavimentos e coberturas), duplicação dos vãos envidraçados simples, conferindo-lhes melhores caraterísticas térmicas, e pela aplicação de proteções solar. Foram ainda adotadas MCE aos sistemas AVAC, designadamente, pela adoção de recuperadores de calor nas Unidades de Tratamento de Ar Novo (UTAN’s) e de variadores de velocidade nas bombas de circulação de água e nos ventiladores de ar das UTAN’s. Pretendia o ISQ concluir se a aplicação de todas as MCE contribuiu de forma efetiva para o dimensionamento de sistemas e equipamentos AVAC de menor capacidade e, consequentemente, numa redução de utilização de energia. Em sequência, pretendia avaliar a viabilidade económica da aplicação de todas as MCE, estimando o sobrecusto inicial e o tempo necessário para o retorno financeiro daquele investimento. Para alcançar os objetivos propostos, procedeu-se à simulação energética dinâmica do ECOTERMOLAB, utilizando o programa EnergyPlus. Primeiro foi simulada uma situação base do edifício, sem quaisquer MCE. Posteriormente foi caraterizada cada uma das situações de aplicação das MCE, com o objetivo de avaliar o respetivo impacto individual na utilização de energia pelos sistemas AVAC. Por último foram assumidas todas as soluções em conjunto para avaliar o impacto final de todas as MCE na utilização de energia dos sistemas AVAC, bem como no seu dimensionamento. Das simulações dinâmicas foram obtidos os valores das necessidades de aquecimento e arrefecimento, de energia utilizada pelos sistemas AVAC e de caudais de água aquecida e arrefecida circulada. Com estes valores foi feita uma estimativa de dimensionamento dos equipamentos e componentes AVAC para as situações da aplicação de todas as MCE no ECOTERMOLAB e a sua ausência. A partir da diferença dos custos de aquisição dos respetivos equipamentos e dos valores de poupança em energia foi realizado o estudo da viabilidade económica da implementação das MCE neste edifício. Este estudo permitiu concluir que a aplicação das MCE no ECOTERMOLAB levou à redução da dimensão na generalidade dos equipamentos e componentes AVAC. Permitiu, ainda, concluir que houve uma diminuição de utilização de energia por parte destes sistemas e equipamentos para o aquecimento e arrefecimento. Conclui-se ainda que o período de retorno (Payback) do sobrecusto inicial, estimado em 37.822€ é de, aproximadamente, onze anos e meio, para um valor atual líquido (VAL) de 8.061€ e à taxa interna de rentabilidade (TIR) de 7,03%.

Coalition of distributed generation units to Virtual Power Players - a game theory approach

Smart Grids (SGs) have emerged as the new paradigm for power system operation and management, being designed to include large amounts of distributed energy resources. This new paradigm requires new Energy Resource Management (ERM) methodologies considering different operation strategies and the existence of new management players such as several types of aggregators. This paper proposes a methodology to facilitate the coalition between distributed generation units originating Virtual Power Players (VPP) considering a game theory approach. The proposed approach consists in the analysis of the classifications that were attributed by each VPP to the distributed generation units, as well as in the analysis of the previous established contracts by each player. The proposed classification model is based in fourteen parameters including technical, economical and behavioural ones. Depending of the VPP strategies, size and goals, each parameter has different importance. VPP can also manage other type of energy resources, like storage units, electric vehicles, demand response programs or even parts of the MV and LV distribution network. A case study with twelve VPPs with different characteristics and one hundred and fifty real distributed generation units is included in the paper.

Factors associated to infection by Toxoplasma gondii in pregnant women attended in Basic Health Units in the city of Rolândia, Paraná, Brazil

The aim of the present work was to determine the prevalence of IgG and IgM anti-Toxoplasma gondii antibodies and the factors associated to the infection in pregnant women attended in Basic Health Units in Rolândia, Paraná, Brazil. The sample was divided in two groups: group I (320 pregnant women who were analyzed from July 2007 to February 2008) and group II (287 pregnant women who were analyzed from March to October 2008). In group I, it was found 53.1% of pregnant women with IgG reactive and IgM non-reactive, 1.9% with IgG and IgM reactive, 0.3% with IgG non-reactive and IgM reactive and 44.7% with IgG and IgM non-reactive. In group II, it was found 55.1% with IgG reactive and IgM non-reactive and 44.9% with IgG and IgM non-reactive. The variables associated to the presence of IgG antibodies were: residence in rural areas, pregnant women between 35-40 years old, low educational level, low family income, more than one pregnancy, drinking water which does not originate from the public water supply system and the habit of handling soil or sand. Guidance on primary prevention measures and the quarterly serological monitoring of the pregnant women in the risk group are important measures to prevent congenital toxoplasmosis.

HRM specificities’ on Portugal hotel units

This paper presents the main Human Resources Management (HRM) specificities’ on Portuguese hotel units. We try to understand the role of HRM on behavior of co-workers and quality service in hotel units and to know the future tendency of human capital profile on Portuguese hotel units and the role of HRM function on management of their staff. We, also, try to explore if Portuguese culture has influence on HRM specificities’ of hotel units. This phenomenon has a special relevance in the Portuguese context, because this country is known a growing process of tourism industry in recent years. Furthermore, little is known about HRM department’ contributions to their human capital management and development. This paper is one of the first to focus specifically on Portuguese hotel units and it also seeks to present findings that stem from the Human Resources Managers’ perspective. The paper is based on qualitative case studies. The data were collected through semi-structured interviews of 12 human resource managers from 12 hotel units located in Portugal. The results show that although there is not an effective HRM, current HRM practices are enough to encouraging pro-environmental behavior in their staff and they have a direct effect on customer satisfaction and competitiveness of sector. However, managers recognize there is need introduce some change on short-term to promote a better performance of staff with effect on customers satisfaction and competitiveness on sector in Portugal. According to these results, the paper discusses the major theoretical and practical implications.

Mosaic Trisomy 18 in a Five-Month-Old Infant - Case Report

Individuals with mosaic trisomy 18, only approximately 5% of all trisomy 18 cases, carry both a trisomy 18 and an euploid cell line. Their clinical findings are highly variable, from the absence of dysmorphic features to the complete trisomy 18 syndrome. A five month old daughter of a 38-year-old mother, with vomiting and feeding problems, was referred to our department. She was undernourished and had axial hypotony and developmental delay, an irregular pattern of hypopigmentation on the right side of the abdomen, and moderate sagittal body asymmetry with left-side muscular hemihypotrophy.Mild craniofacial dysmorphy included dolichocephaly, frontal bossing, prominent occiput, long downslanting palpebral fissures, hypertelorism, and retrognathia. A complex heart defect with atrial and ventricular septal defects, pulmonary artery stenosis, and bicuspid aortic valve was identified. Cytogenetic analysis revealedmosaic trisomy 18with trisomy in 90%of peripheral lymphocytes and 17%of skin fibroblasts.This case adds to our knowledge of the phenotypic spectrum and the natural history of mosaic trisomy 18 by adding a dysmorphic feature and a cardiac abnormality that, to the best of our knowledge, had not been previously described.

Characterizing the Risk Profiles of Intensive Care Units

OBJECTIVE: To develop a new method to evaluate the performance of individual ICUs through the calculation and visualisation of risk profiles. METHODS: The study included 102,561 patients consecutively admitted to 77 ICUs in Austria. We customized the function which predicts hospital mortality (using SAPS II) for each ICU. We then compared the risks of hospital mortality resulting from this function with the risks which would be obtained using the original function. The derived risk ratio was then plotted together with point-wise confidence intervals in order to visualise the individual risk profile of each ICU over the whole spectrum of expected hospital mortality. MAIN MEASUREMENTS AND RESULTS: We calculated risk profiles for all ICUs in the ASDI data set according to the proposed method. We show examples how the clinical performance of ICUs may depend on the severity of illness of their patients. Both the distribution of the Hosmer-Lemeshow goodness-of-fit test statistics and the histogram of the corresponding P values demonstrated a good fit of the individual risk models. CONCLUSIONS: Our risk profile model makes it possible to evaluate ICUs on the basis of the specific risk for patients to die compared to a reference sample over the whole spectrum of hospital mortality. Thus, ICUs at different levels of severity of illness can be directly compared, giving a clear advantage over the use of the conventional single point estimate of the overall observed-to-expected mortality ratio.

POLYCLONAL OUTBREAK OF BLOODSTREAM INFECTIONS CAUSED BY Burkholderia cepacia COMPLEX IN HEMATOLOGY AND BONE MARROW TRANSPLANT OUTPATIENT UNITS

Aim: The objective was to describe an outbreak of bloodstream infections by Burkholderia cepacia complex (Bcc) in bone marrow transplant and hematology outpatients.Methods: On February 15, 2008 a Bcc outbreak was suspected. 24 cases were identified. Demographic and clinical data were evaluated. Environment and healthcare workers' (HCW) hands were cultured. Species were determined and typed. Reinforcement of hand hygiene, central venous catheter (CVC) care, infusion therapy, and maintenance of laminar flow cabinet were undertaken. 16 different HCWs had cared for the CVCs. Multi-dose heparin and saline were prepared on counter common to both units.Findings: 14 patients had B. multivorans(one patient had also B. cenopacia), six non-multivorans Bcc and one did not belong to Bcc. Clone A B. multivorans occurred in 12 patients (from Hematology); in 10 their CVC had been used on February 11/12. Environmental and HCW cultures were negative. All patients were treated with meropenem, and ceftazidime lock-therapy. Eight patients (30%) were hospitalized. No deaths occurred. After control measures (multidose vial for single patient; CVC lock with ceftazidime; cleaning of laminar flow cabinet; hand hygiene improvement; use of cabinet to store prepared medication), no new cases occurred.Conclusions: This polyclonal outbreak may be explained by a common source containing multiple species of Bcc, maybe the laminar flow cabinet common to both units. There may have been contamination by B. multivorans (clone A) of multi-dose vials.

TOXOPLASMOSIS-RELATED KNOWLEDGE AMONG PREGNANT AND POSTPARTUM WOMEN ATTENDED IN PUBLIC HEALTH UNITS IN NITERÓI, RIO DE JANEIRO, BRAZIL

The present study conducted a toxoplasmosis-related knowledge level survey with 400 pregnant and puerperal women attended in public health units in the municipality of Niterói, Rio de Janeiro. Only 111 (27.8%) women claimed to know about the disease. Most of them (n = 289; 72.2%) had never heard about toxoplasmosis nor knew how to prevent the infection by Toxoplasma gondii. A significant difference (p = 0.013) regarding the presence of anti-T. gondii IgG was observed between women who claimed to know about the disease and those who had never heard about it. These results highlight the importance of a systematic serological screening process for toxoplasmosis, as well as the importance of primary prevention by accurate information during prenatal care, an important Public Health action to be implemented.
