Tuberculosis among health care workers in a Brazilian tertiary hospital emergency unit

The Brazilian emergency system is being reorganized as a hierarchy in the region of Ribeirao Preto, state of Sao Paulo. We found increased occupational risk for tuberculosis in this region tertiary reference center-a nurse technician (Incidence rate [IR] 526.3/100000 inhabitants) had a risk of tuberculosis 12.6 (95% confidence interval [CI], 2.57-37.23) greater than the city population (41.8/100000 inhabitants). The system reorganization will have to make the centers adequate to deal with this problem. (C) 2008 Elsevier Inc. All rights reserved.

Improving pain management by nurses: A pilot peer intervention program

Significant pain continues to be reported by many hospitalized patients despite the numerous and varied educational programs developed and implemented to improve pain management. A theoretically based Peer Intervention Program was designed from a predictive model to address nurses' beliefs, attitudes, subjective norms, self-efficacy, perceived control and intentions in the management of pain with p.r.n. (as required) narcotic analgesia. The pilot study of this program utilized a quasi-experimental pre-post test design with a patient intervention, nurse and patient intervention and control conditions consisting of 24, 18 and 19 nurses, respectively. One week after the intervention, significant differences were found between the nurse and patient condition and the two other conditions in beliefs, self-efficacy, perceived control, positive trend in attitudes, subjective norms and intentions. The most positive aspects of the program were supportive interactive discussions with peers and an awareness and understanding of beliefs and attitudes and their roles in behavior.

Community attitudes to researchers

A non-Indigenous researcher who previously worked as a remote community nurse provides insights into how non-Indigenous researchers are viewed by non-Indigenous practitioners in those settings because in Australian Aboriginal communities most community health nurses had a cynical view of visiting researchers. These attitudes illustrate the need for the establishment of mutually fulfilling relationships with those among whom they work.

Detection of the initial infective stages of the protozoan parasite Marteilia sydneyi in Saccostrea glomerata and their development through to sporogenesis

DNA probes were used in in situ hybridisation on histological sections of oysters exposed for defined intervals to Marteilia sydneyi infection to reveal the early development of the parasite in the oyster host, Saccostrea glomerata. The initial infective stages enter through the palps and gills whereupon extrasporogonic proliferation results in the liberation of cells into surrounding connective tissue and haemolymph spaces. Following systemic dissemination, the parasite infiltrates the digestive gland and becomes established as a nurse cell beneath the epithelial cells ill a digestive tubule. Here, cell-within-cell proliferation results in the eventual liberation of daughter cells from the nurse cell into spaces between adjacent epithelial cells. None of these stages had previously been described. Proliferation is associated with host responses, including haemocytic infiltration of the connective tissue and diapedesis across tubule epithelia. The responses cease as sporogenesis begins. (C) 2002 Australian Society for Parasitology Inc. Published by Elsevier Science Ltd. All rights reserved.

High dependency units: Issues to consider in their planning

This review discusses the issues to be considered in establishing new or extending existing high dependency unit (HDU) services. A defined high dependency service becomes cost-effective when patient care requires more than one nurse for three patients. Professional guidelines for HDUs vary and there are no national accreditation criteria. Casemix and service delivery specifications for the HDU need to be defined and agreed upon within the institution. Establishing a new HDU service requires changes to care delivery. Many potential HDU patients are currently managed in general wards or in the intensive care unit. The service should be discussed widely and marketed within the institution, and the development of defined working relationships with the ICU and primary care teams oil the wards is mandatory.

Behaviour of caregivers to protect their infants from exposure to the sun in Queensland, Australia.

Exposure to the sun by infants has been demonstrated to increase the risk of the development of melanoma and other skin cancers later in life. A cohort of 508 women who delivered healthy Caucasian babies were followed up at 1 year to determine their knowledge, attitudes and practices regarding sun protection towards themselves and their child. In addition, the 1-year-old infants were assessed by a trained nurse for the number of nevi they had on their skin. Results indicate caregivers reported a high level of sun-protection practices towards their child, with 93% of the caregivers reporting usually or always placing the child in the shade when going outside. Further, 81% of the caregivers reported usually or always placing a hat on the child, while 64% reported usually or always applying sunscreen to the child's exposed skin. Interestingly, only 61% of the caregivers reported that they stayed in the shade to reduce sun exposure and only 42% wore a hat when out in the sun. Mother's own personal sun-protection methods predicted the method of sun protection that she would most likely use for the child. While children appear to be reasonably protected from the sun, they are influenced by their mother's own behaviors.

Melanocytic nevi, solar keratoses, and divergent pathways to cutaneous melanoma

Background: Some melanomas form on sun-exposed body sites, whereas others do not. We previously proposed that melanomas at different body sites arise through different pathways that have different associations with melanocytic nevi and solar keratoses. We tested this hypothesis in a case-case comparative study of melanoma patients in Queensland, Australia. Methods: We randomly selected patients from among three prespecified groups reported to the population-based Queensland Cancer Registry: those with superficial spreading or nodular melanomas of the trunk (n = 154, the reference group), those with such melanomas of the head and neck (n = 77, the main comparison group), and those with lentigo maligna melanoma (LMM) (n = 75, the chronic sun-exposed group). Each participant completed a questionnaire, and a research nurse counted melanocytic nevi and solar keratoses. We calculated exposure odds ratios (ORs) and 95% confidence intervals (CIs) to quantify the association between factors of interest and each melanoma group. Results: Patients with head and neck melanomas, compared with patients with melanomas of the trunk, were statistically significantly less likely to have more than 60 nevi (OR = 0.34, 95% CI = 0.15 to 0.79) but were statistically significantly more likely to have more than 20 solar keratoses (OR = 3.61, 95% CI = 1.42 to 9.17) and also tended to have a past history of excised solar skin lesions (OR = 1.87, 95% CI = 0.89 to 3.92). Patients with LMM were also less likely than patients with truncal melanomas to have more than 60 nevi (OR = 0.32, 95% CI = 0.14 to 0.75) and tended toward more solar keratoses (OR = 2.14, 95% CI = 0.88 to 5.16). Conclusions: Prevalences of nevi and solar keratoses differ markedly between patients with head and neck melanomas or LMM and patients with melanomas of the trunk. Cutaneous melanomas may arise through two pathways, one associated with melanocyte proliferation and the other with chronic exposure to sunlight.

Effect of central venous catheter type on infections: a prospective clinical trial

This study reports on a block clinical trial of two types of central venous catheters (CVCs): antiseptic-impregnated catheters (AIC) and non-impregnated catheters (non-AIC), on catheter tip colonization and bacteraemia. In total, 500 catheters were inserted in 390 patients over the 18 month study period, 260 (52.0%) AIC and 240 (48.0%) non-AIC. Of these, 460 (92.0%) tips (237 AIC and 223 non-AIC) were collected. While significantly fewer AIC, 14 (5.9%), than non-AIC, 30 (13.5%), catheters were colonized (P < 0.01), there was no difference in the rates of bacteraemias in the two groups (0.8% vs. 2.7%, respectively, P = 0.16). There were 6.87 (95% CI 3.38-14.26) and 16.92 (95% CI 10.61-27.12) colonized AIC and non-AIC catheters, respectively, per 1000 catheter days, a difference that was significant (P < 0.01). However, no difference emerged between bacteraemias in AIC and non-AIC catheters per 1000 catheter days measured at 0.98 (95% CI 0.24-5.54) and 3.38 (95% CI 1.29-9.34), respectively (P = 0.10). Of the 444 CVCs that were sited in the subclavian or jugular veins and had tips collected, significantly more catheters were colonized in the jugular group, 19 (20%), compared with the subclavian group, 24 (6.9%; P less than or equal to 0.01). Overall, the low rates of colonization and bacteraemia may be explained by the population studied, the policies used and the employment of a clinical nurse dedicated to CVC management.

O agir cotidiano dos gestores da Estratégia Saúde da Família em um município do Espírito Santo

O Sistema único de Saúde (SUS) pode ser considerado uma das maiores conquistas sociais consagradas na Constituição de 1988, representando a materialização de uma nova concepção acerca da saúde no Brasil. As diretrizes do SUS são importantes instrumentos indutores de mudanças e modernização da gestão, incluindo aspectos relativos à organização da assistência, como sua humanização e também a busca de maiores níveis de desempenho e responsabilidade institucional para com os resultados alcançados. Diversos autores tem se debruçado sobre o tema gestão, porém, qual o modelo de gestão que conseguiria combinar um papel ativo, de liderança e de coordenação para gestores com autonomia? Este estudo objetiva analisar a prática da gestão nos serviços de saúde do município de Itapemirim/ES, buscando compreender as múltiplas e complexas dimensões que orientam essa prática, tendo como principal fonte as entrevistas de seus gestores. O município adota uma política de gestão participativa na saúde com várias instâncias formais e pratica um investimento em saúde acima do preconizado pela Constituição Federal o que permite um investimento em estruturação e oferta de serviços públicos. Do ponto de vista metodológico, o estudo adota a abordagem qualitativa através de entrevistas semiestruturadas, focalizando a gestão como um mundo social e expressão dos processos presentes nas organizações e que atravessam os relatos coletados. Foram entrevistados três gestores, sendo esses, Secretário Municipal de Saúde, Diretora da Atenção Primária em Saúde e Coordenadora de Estratégia Saúde da Família do município de Itapemirim. A análise do material empírico teve como um de seus eixos o estudo do percurso profissional dos gestores, especialmente os processos que os levaram à função de gestão. A contingência marca essas trajetórias que se desenrolam em um contexto em que, em alguns dos casos, percebe-se que não existe qualquer exigência quanto à formação de gestão. Outro eixo abordado são as práticas de gestão onde são examinados os sentidos que o exercício da função de gestor tem para os sujeitos, como também as suas estratégias de trabalho, planejamento e ferramentas de uso. O exame das práticas de gestão norteia-se pela análise das possibilidades e limites para desencadear processos de mudança. Os depoimentos apontam as características dessas experiências de gestão, que procuram construir condições para processos de mudança, seja através das experiências anteriores desses gestores ou das estratégias de trabalho e do sistema de gestão articulado que procuram desenvolver. Os projetos profissionais dos gestores entrevistadas vão claramente se definindo no âmbito da gestão: se veem, não mais como profissionais de sua área de formação original (enfermeiro, farmacêutico ou cirurgião dentista), mas acima de tudo como gestores, alimentados pelo reconhecimento de suas capacidades de mobilização e de desenvolvimento de mudanças relativas a outras realizações no campo da gestão.

Percursos e identidades. A (re)construção da identidade profissional do docente de enfermagem: o olhar dos docentes

RESUMO: Considerando a identidade como um processo dinâmico de interacção social, afastando-nos da ideia de identidades pré-estabelecidas, ancoradas numa visão essencialista e, aproximando-nos de uma identidade profissional que se constrói através de sucessivas interacções, procurámos conhecer a identidade profissional do docente de enfermagem. Convictos de que o estudo da identidade pode oscilar entre um pólo individual e um estrutural, optámos pela dimensão biográfica como eixo estruturante deste trabalho. Efectuaram-se oito biografias a docentes integrados no conceito de perito com uma profissionalidade reflectida. Utilizámos ainda o focus group como método complementar. Constatámos que os actores deste estudo se sentem enfermeiros, embora a sua área de actuação seja a docência. Destacam a integração do ensino de enfermagem no ensino superior como determinante na mudança da sua representação social. Todos estes docentes se incluem nos grupos que apresentam um estatuto da identidade realizado ou outorgado. Das competências que devem estar presentes no docente de enfermagem, salientam-se a comunicação, actualização científica e relação, capazes de promover um ambiente que propicie as aprendizagens significativas, de internacionalização, de investigação, como um modelo de conduta a seguir, que participe na vida da organização e seja capaz de motivar o outro, mas sobretudo que seja um bom enfermeiro. ABSTRACT: Considering identity as a social dynamic integration process, departing from the concept of pre-established identities anchored in an essentialist vision, and approaching a professional identity built trough successive interaction, we aimed to know the professional identity of the nursing teacher. Believing that the identity study may oscillate between an individual and a structural pole, we have chosen the biographic dimension as the structural axis for this assignment. Eight biographies from teachers integrated in the expert with a reflective professional identity have been made. We have also used the focus group as a complementary method. We have seen that the actors of this study feel themselves as nurses although their working area is teaching. They point out the higher teaching of Nursing as a determinant in the change of their social representation. All of these teachers are included in the groups that present an identity status that has been fulfilled or attributed. From the skills that should be present in the nursing teacher, communication, scientific knowledge and relationship are indicated when these are able to provide significant learning, internationalization and research as a behaviour model to be followed regarding the life of the organization and that might incentive others, but above as a way to be a good nurse.

Health, sleep and lack of time: relations to domestic and paid work in nurses

OBJECTIVE: To assess whether reported morbidity and complaints of lack of time and sleep are associated with the burden of professional work and housework among nurses. METHODS: A cross-sectional exploratory study was carried out among female nurses and nurse assistants (N=206) of a public hospital in Rio de Janeiro, Brazil. Data were collected by means of a questionnaire. The prevalence ratio and 95% confidence intervals were estimated. RESULTS: Mean duration of professional work and housework time was 40.4 and 31.6 hours/week, respectively. Long professional working time (over 44 hours/week) were associated with mild emotional disorders (PR=1.37; 95% CI: 1.05-1.80), complaints of lack of time for resting/leisure (PR=1.61; 95% CI: 1.31-1.97), housework (PR=1.48; 95% CI: 1.12-1.97), and childcare (PR=1.99; 95% CI: 1.51-2.63). Long housework time (over 28 hours/week) was associated with lower prevalence of lack of time for childcare (PR=0.62; 95% CI: 0.46-0.84). High housework load was associated with lack of personal time and complaints of varicose veins (PR=1.31; 95% CI: 1.14-1.50 and PR=1.31; 95% CI: 1.08-1.58, respectively). Complaints of varicose veins were also frequent among female nurses with a total work load above 84 hours (PR=1.30; 95% CI: 1.05-1.61), though this group has shown a lower prevalence of arterial hypertension and recurrent headaches (PR=0.35; 95% CI: 0.15-0.83 and PR=0.53; 95% CI: 0.32-0.89, respectively). CONCLUSIONS: Results suggest that both professional and home environments are relevant in the evaluation of work overload on nurses' health and their family and social life. It is stressed the need for instruments for analyzing total workload among female populations.

A efectividade da intervenção da fisioterapia nas disfunções crânio- cervico-mandibulares

Introdução: As teorias etiológicas recíprocas que relacionam as disfunções da articulação temporo mandibular (ATM) com as disfunções da coluna cervical, os seus critérios de diagnóstico e formas de tratamento, não reúnem consenso, constituindo, actualmente, uma temática de debate e investigação. Objectivo: Descrever a avaliação e intervenção em fisioterapia, e os seus resultados numa utente com disfunção do complexo crânio-cervico-mandibular. Métodos: Foi realizado um estudo observacional descritivo, do tipo estudo de caso, reportando-se a uma enfermeira, de 28 anos, com quadro sintomatológico compatível com disfunção crânio-cervico-mandibular, com antecedentes de condilectomia e artroplastia da ATM, aos 14 anos. Inicialmente a utente apresentava dor irradiada na região cervical (7/10) e limitação dos movimentos articulares da coluna cervical. Referia, também, dor na região do ptérion direito (6/10), limitação dos movimentos da mandíbula, desvio lateral na abertura da boca e dificuldades funcionais na mastigação. A avaliação inicial e final (após tratamento), foi efectuada recorrendo-se à utilização do Goniometro CROM e da Therabite Range of Motion Scale, para medição das amplitudes articulares da cervical e ATM, respectivamente; Estetoscópio, para avaliação dos sons articulares da ATM; Escala Visual Analógica para graduação da dor. A intervenção decorreu ao longo de 10 sessões, bissemanais. No tratamento, foram aplicadas técnicas sobre os trigers points da musculatura cervical e músculos da mastigação; Mobilização passiva da cervical e ATM; Manipulação dos segmentos vertebrais cervicais e torácicos; Streching e técnicas de energia muscular; Técnicas funcionais para a ATM; Técnicas miofasciais para a coluna cervical e ATM; Exercícios de controlo motor da coluna cervical. Resultados: No final do tratamento, as amplitudes dos movimentos cervicais estavam completas e sem dor (0/10), mantendo, sensibilidade dolorosa à palpação das espinhosas de C5-C6 (1/10). Relativamente à ATM, verifica-se a abolição da dor (0/10) e a ausência do desvio lateral da mandíbula na abertura da boca, bem como, o aumento das amplitudes de movimento na abertura da boca (33 para 36 mm), e no desvio lateral esquerdo (2 para 2,8 mm). Conclusão: os resultados sugerem que a intervenção, com recurso a técnicas de terapia manual, no caso em estudo, parecem surtir efeitos positivos no quadro sintomatológico e funcional da utente.

Assessment of nursing students and nurses' orientation towards patient-centeredness

Background - Being patient centered is a core value for nursing. Patient centered-care has been related to patient and health provider satisfaction, better health outcomes, higher quality of care and more efficient health care delivery. Objectives - The purpose was to assess the orientation adopted by nurses and students in patient care, using The Patient-Practitioner Orientation Scale, as well as to compare the results between resident nurses and students from different academic years. Settings - Public School of Nursing and a Central Hospital, in Lisbon (Portugal). Participants - Students in the first, second and fourth year of nursing school and nurses participated in the study. Methods - For data collection, we used The Patient-Practitioner Orientation Scale (European Portuguese version), an instrument designed to measure individual preferences toward the dimension of caring a sharing in health professional-patient relationship. Students and nurses also filled out two additional questions about their perception of competence in technical and communication skills. Additional demographic information was also collected, including gender, age, academic year and length of professional experience. Results - A total of 525 students (84.7% female) and 108 nurses (77.8% female) participated in this study. In general, caring sub-scores, measuring the preference of about attending to patient emotional aspects, were higher than sharing sub-scores, measuring beliefs about giving information and perceiving patient as a member of the health team. Students were significantly more patient-centered throughout their nursing education (p<0.001). Comparing to students in the second and fourth academic years (p<0.001) nurses' scores were significantly lower both in total PPOS and in caring and sharing subscales. Conclusions - These results reinforce the idea that patient centeredness may be developed in academic context. The scores obtained highlight the importance of studies that aim to identify factors that may explain the decrease of patient centeredness in professional practice.
