An exploration of how clinician attitudes and beliefs influence the implementation of lifestyle risk factor management in primary healthcare: a grounded theory study
BackgroundDespite the effectiveness of brief lifestyle intervention delivered in primary healthcare (PHC), implementation in routine practice remains suboptimal. Beliefs and attitudes have been shown to be associated with risk factor management practices, but little is known about the process by which clinicians\u27 perceptions shape implementation. This study aims to describe a theoretical model to understand how clinicians\u27 perceptions shape the implementation of lifestyle risk factor management in routine practice. The implications of the model for enhancing practices will also be discussed.MethodsThe study analysed data collected as part of a larger feasibility project of risk factor management in three community health teams in New South Wales (NSW), Australia. This included journal notes kept through the implementation of the project, and interviews with 48 participants comprising 23 clinicians (including community nurses, allied health practitioners and an Aboriginal health worker), five managers, and two project officers. Data were analysed using grounded theory principles of open, focused, and theoretical coding and constant comparative techniques to construct a model grounded in the data.ResultsThe model suggests that implementation reflects both clinician beliefs about whether they should (commitment) and can (capacity) address lifestyle issues. Commitment represents the priority placed on risk factor management and reflects beliefs about role responsibility congruence, client receptiveness, and the likely impact of intervening. Clinician beliefs about their capacity for risk factor management reflect their views about self-efficacy, role support, and the fit between risk factor management ways of working. The model suggests that clinicians formulate different expectations and intentions about how they will intervene based on these beliefs about commitment and capacity and their philosophical views about appropriate ways to intervene. These expectations then provide a cognitive framework guiding their risk factor management practices. Finally, clinicians\u27 appraisal of the overall benefits versus costs of addressing lifestyle issues acts to positively or negatively reinforce their commitment to implementing these practices.ConclusionThe model extends previous research by outlining a process by which clinicians\u27 perceptions shape implementation of lifestyle risk factor management in routine practice. This provides new insights to inform the development of effective strategies to improve such practices
Contingency management interventions for tobacco and other substance use disorders in pregnancy.
Contingency management (CM) is an effective intervention for reducing use of licit and illicit substances in a variety of populations. Pregnant women are a vulnerable population with much to gain from effective interventions for substance use disorders, and for whom CM interventions may be especially well-suited. We reviewed the literature on CM interventions among pregnant women with tobacco and other substance use disorders with 3 aims: (a) describe the effectiveness of CM for reducing use of tobacco and other substances during pregnancy, (b) describe the effects of CM interventions on infant outcomes, and (c) identify needs for future research on CM in pregnancy. Our search strategy revealed 27 primary studies of CM in pregnancy. CM was effective in the majority of studies targeting nicotine abstinence, and results were mixed in studies targeting illicit substances. A variety of methodologies were used within the relatively small number of studies making it difficult to identify underlying mechanisms. Also, very few studies reported maternal and infant outcomes, and significant effects of CM were only apparent when secondary analyses pooled data from multiple studies. Furthermore, there is extremely limited data on the cost effectiveness of CM interventions in pregnancy. Future research should address these 3 areas to better determine the ultimate value of CM as an efficacious treatment for pregnant women with substance use disorders. (PsycINFO Database Recor
Aversão à desigualdade e preferências por redistribuição: A percepção de mobilidade econômica as afeta no Brasil?
Resumo A noção de que a redistribuição é dos ricos para os pobres permitiria concluir a priori que os pobres são os principais partidários de medidas redistributivas, ao serem os potenciais beneficiários. Não obstante, estudos realizados principalmente para países desenvolvidos sugerem que a aversão à desigualdade e as preferências por redistribuição são moldadas por fatores que vão além do pecuniário. Neste trabalho, analisa-se o efeito da mobilidade econômica subjetiva na aversão à desigualdade e na demanda por redistribuição dos brasileiros, usando-se uma base de dados única, representativa do país, coletada em 2012. Os resultados sugerem que, em contradição com previsões teóricas e com evidências de países desenvolvidos, mesmo pessoas que aspiram ascender socialmente no futuro incomodam-se com a desigualdade e são favoráveis a políticas redistributivas. Brasileiros que perceberam uma piora na sua situação econômica também mostram-se favoráveis à redistribuição, resultado mais convencional. Ambos os conjuntos de resultados são confirmados por estimações feitas em subamostras definidas por renda familiar. Levantam-se hipóteses para se tentar explicar os resultados inesperados
Development and Applications of Fluorogen/Light-Up RNA Aptamer Pairs for RNA Detection and More.
The central role of RNA in living systems made it highly desirable to have noninvasive and sensitive technologies allowing for imaging the synthesis and the location of these molecules in living cells. This need motivated the development of small pro-fluorescent molecules called "fluorogens" that become fluorescent upon binding to genetically encodable RNAs called "light-up aptamers." Yet, the development of these fluorogen/light-up RNA pairs is a long and thorough process starting with the careful design of the fluorogen and pursued by the selection of a specific and efficient synthetic aptamer. This chapter summarizes the main design and the selection strategies used up to now prior to introducing the main pairs. Then, the vast application potential of these molecules for live-cell RNA imaging and other applications is presented and discussed.journal article2020importe
