    Lake Cadagno is characterized by a compact chemocline that harbors high concentrations of various phototrophic sulfur bacteria. Four strains representing the numerically most abundant populations in the chemocline were tested in dialysis bags in situ for their ability to fix CO2. The purple sulfur bacterium Candidatus ‘Thiodictyon syntrophicum' strain Cad16T had the highest CO2 assimilation rate in the light of the four strains tested and had a high CO2 assimilation rate even in the dark. The CO2 assimilation of the population represented by strain Cad16T was estimated to be up to 25% of the total primary production in the chemocline. Pure cultures of strain Cad16T exposed to cycles of 12 h of light and 12 h of darkness exhibited the highest CO2 assimilation during the first 4 h of light. The draft genome sequence of Cad16T showed the presence of cbbL and cbbM genes, which encode form I and form II of RuBisCO, respectively. Transcription analyses confirmed that, whereas cbbM remained poorly expressed throughout light and dark exposure, cbbL expression varied during the light-dark cycle and was affected by the available carbon sources. Interestingly, the peaks in cbbL expression did not correlate with the peaks in CO2 assimilatio

    Abstract OBJECTIVE To understand the nursing professionals' conceptions of teamwork and their elements. METHOD A qualitative study conducted in an oncological hospital using a semi-structured interview with 21 nursing professionals. RESULTS Two conceptions emerged from the accounts: teamwork restricted to nursing professionals and teamwork with interprofessional collaboration with particular importance for interactive dimensions: communication, trust and professional bonds, mutual respect and recognition of the other's work, collaboration, and conflict, with this last subcategory considered as an obstacle to teamwork. CONCLUSION Nursing conceives teamwork as an interprofessional practice, which is a result of the quality of interaction among professionals from different areas and involves the recognition and handling of conflicts

    BACKGROUND: An estimated 2.5 billion people worldwide lack access to improved sanitation facilities. While large-scale programs in some countries have increased latrine coverage, they sometimes fail to ensure optimal latrine use, including the safe disposal of child feces, a significant source of exposure to fecal pathogens. We undertook a cross-sectional study to explore fecal disposal practices among children in rural Orissa, India in villages where the Government of India's Total Sanitation Campaign had been implemented at least three years prior to the study. METHODS AND FINDINGS: We conducted surveys with heads of 136 households with 145 children under 5 years of age in 20 villages. We describe defecation and feces disposal practices and explore associations between safe disposal and risk factors. Respondents reported that children commonly defecated on the ground, either inside the household (57.5%) for pre-ambulatory children or around the compound (55.2%) for ambulatory children. Twenty percent of pre-ambulatory children used potties and nappies; the same percentage of ambulatory children defecated in a latrine. While 78.6% of study children came from 106 households with a latrine, less than a quarter (22.8%) reported using them for disposal of child feces. Most child feces were deposited with other household waste, both for pre-ambulatory (67.5%) and ambulatory (58.1%) children. After restricting the analysis to households owning a latrine, the use of a nappy or potty was associated with safe disposal of feces (OR 6.72, 95%CI 1.02-44.38) though due to small sample size the regression could not adjust for confounders. CONCLUSIONS: In the area surveyed, the Total Sanitation Campaign has not led to high levels of safe disposal of child feces. Further research is needed to identify the actual scope of this potential gap in programming, the health risk presented and interventions to minimize any adverse effect

    Contributions of team climate in the study of interprofessional collaboration: a conceptual analysis

    Get PDF
    The concept of team climate is widely used to understand and evaluate working environments. It shares some important features with Interprofessional Collaboration (IPC). The four-factor theory of climate for work group innovation, which underpins team climate, could provide a better basis for understanding both teamwork and IPC. This article examines in detail the common ground between team climate and IPC, and assesses the relevance of team climate as a theoretical approach to understanding IPC. There are important potential areas of overlap between team climate and IPC that we have grouped under four headings: (1) interaction and communication between team members; (2) common objectives around which collective work is organised; (3) responsibility for performing work to a high standard; and (4) promoting innovation in working practices. These overlapping areas suggest common characteristics that could provide elements of a framework for considering the contribution of team climate to collaborative working, both from a conceptual perspective and, potentially, in operational terms as, for example, a diagnostic tool

    Educação no trabalho na atenção primĂĄria Ă  saĂșde: interfaces entre a educação permanente em saĂșde e o agir comunicativo

    Get PDF
    O trabalho em saĂșde e a educação no trabalho constituem-se com uma dupla dimensĂŁo - ação instrumental e intersubjetividade. OBJETIVO: Analisar as concepçÔes de educação que fundamentam as atividades educativas de trabalhadores da saĂșde na atenção primĂĄria. MÉTODO: Estudo de abordagem qualitativa realizado em duas unidades bĂĄsicas de saĂșde do municĂ­pio de SĂŁo Paulo, por meio de entrevista semiestruturada gravada com 36 informantes-chave, representativos de cada categoria profissional dos serviços, incluindo o segmento gerencial e o de trabalhadores da saĂșde. Os dados foram analisados com a tĂ©cnica de anĂĄlise de conteĂșdo temĂĄtica com base no quadro teĂłrico: processo de trabalho em saĂșde, teoria do agir comunicativo, educação continuada (EC), educação permanente em saĂșde (EPS) e integralidade, os quais permitiram a construção das categorias empĂ­ricas: educação instrumental/tradicional e educação comunicativa/emancipatĂłria. Resultados: Os resultados mostram o predomĂ­nio da concepção de educação no trabalho como construção coletiva do saber a partir da realidade de trabalho, pertinentes Ă  EPS que se pretende instituir para a mudança das prĂĄticas e do modelo assistencial biomĂ©dico. Contudo, alguns depoentes expressam uma concepção de educação instrumental com ĂȘnfase em açÔes tĂ©cnicas e de atualização do saber, que se aproxima da EC. CONCLUSÃO: Os resultados evidenciam a convivĂȘncia das duas concepçÔes de educação de trabalhadores - instrumental e comunicativa com o predomĂ­nio da segunda, que mostra a capilaridade da polĂ­tica de EPS entre os trabalhadores de saĂșde das UBS e a necessidade de aprofundar o debate para consolidar a prĂĄtica educativa no cotidiano de trabalho.Health work and work education are a double dimension - instrumental action and intersubjectivity. OBJECTIVE: To analyze the conceptions of education that support educational activities of health care workers in Primary Health Care. METHOD: This qualitative study was conducted in two primary health care units (PHCU) in SĂŁo Paulo, through semi-structured interviews with 36 key informants representing each professional category, including managers and health care workers. Data were analyzed based on thematic content analysis and on the theoretical framework: the healthcare work process, theory of communicative action, continuing education (CE), permanent education in health (PEH) and integrality (comprehensive approach), which allowed the construction of the empirical categories: instrumental/traditional education and communicative/emancipatory education. RESULTS: The results show the prevailing notion of work education as a collective construction of knowledge from the reality of work, relevant to the PEH that is intended to be introduced in order to change the practices and the biomedical health care model. However, some interviewed subjects expressed an instrumental conception of education that emphasizes technical actions and knowledge updating, which is closer to CE. Conclusion: Results show the coexistence of the two conceptions of workers' education: instrumental and communicative, with the predominance of the second one, which shows the reach of the PEH policy among the health workers of PHCU and the need for deepening the discussion to consolidate educational practice in daily work

    Combining estimates of interest in prognostic modelling studies after multiple imputation: current practice and guidelines

    Get PDF
    Background: Multiple imputation (MI) provides an effective approach to handle missing covariate data within prognostic modelling studies, as it can properly account for the missing data uncertainty. The multiply imputed datasets are each analysed using standard prognostic modelling techniques to obtain the estimates of interest. The estimates from each imputed dataset are then combined into one overall estimate and variance, incorporating both the within and between imputation variability. Rubin's rules for combining these multiply imputed estimates are based on asymptotic theory. The resulting combined estimates may be more accurate if the posterior distribution of the population parameter of interest is better approximated by the normal distribution. However, the normality assumption may not be appropriate for all the parameters of interest when analysing prognostic modelling studies, such as predicted survival probabilities and model performance measures. Methods: Guidelines for combining the estimates of interest when analysing prognostic modelling studies are provided. A literature review is performed to identify current practice for combining such estimates in prognostic modelling studies. Results: Methods for combining all reported estimates after MI were not well reported in the current literature. Rubin's rules without applying any transformations were the standard approach used, when any method was stated. Conclusion: The proposed simple guidelines for combining estimates after MI may lead to a wider and more appropriate use of MI in future prognostic modelling studies
