Should I and Can I?: a mixed methods study of clinician beliefs and attitudes in the management of lifestyle risk factors in primary health care

BackgroundPrimary health care (PHC) clinicians have an important role to play in addressing lifestyle risk factors for chronic diseases. However they intervene only rarely, despite the opportunities that arise within their routine clinical practice. Beliefs and attitudes have been shown to be associated with risk factor management practices, but little is known about this for PHC clinicians working outside general practice. The aim of this study was to explore the beliefs and attitudes of PHC clinicians about incorporating lifestyle risk factor management into their routine care and to examine whether these varied according to their self reported level of risk factor management.MethodsA cross sectional survey was undertaken with PHC clinicians (n = 59) in three community health teams. Clinicians\u27 beliefs and attitudes were also explored through qualitative interviews with a purposeful sample of 22 clinicians from the teams. Mixed methods analysis was used to compare beliefs and attitudes for those with high and low levels of self reported risk factor management.ResultsRole congruence, perceived client acceptability, beliefs about capabilities, perceived effectiveness and clinicians\u27 own lifestyle were key themes related to risk factor management practices. Those reporting high levels of risk factor screening and intervention had different beliefs and attitudes to those PHC clinicians who reported lower levels.ConclusionPHC clinicians\u27 level of involvement in risk factor management reflects their beliefs and attitudes about it. This provides insights into ways of intervening to improve the integration of behavioural risk factor management into routine practice

The Evolution of Compact Binary Star Systems

We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the frequency band of ground-based detectors, while compact binaries of WDs are important sources of GWs at lower frequencies to be covered by space interferometers (LISA). Major uncertainties in the current understanding of properties of NSs and BHs most relevant to the GW studies are discussed, including the treatment of the natal kicks which compact stellar remnants acquire during the core collapse of massive stars and the common envelope phase of binary evolution. We discuss the coalescence rates of binary NSs and BHs and prospects for their detections, the formation and evolution of binary WDs and their observational manifestations. Special attention is given to AM CVn-stars -- compact binaries in which the Roche lobe is filled by another WD or a low-mass partially degenerate helium-star, as these stars are thought to be the best LISA verification binary GW sources.Comment: 105 pages, 18 figure

Non-pharmacological interventions for weight gain in patients with schizophrenia taking antipsychotics

INTRODUCTION: Schizophrenic patients have a higher prevalence of obesity than the general population. There are several factors implicated in weight gain, including poor dietary conditions, sedentary lifestyle and antipsychotic drugs use. Obesity is also associated with metabolic disturbances such as diabetes mellitus. Weight gain interventions are necessary in this population, especially non-pharmacological interventions. OBJECTIVE: To review the non-pharmacological interventions for weight gain management in patients with schizophrenia. METHODS: Eight clinical trials and four open-label studies using these interventions were found. The methodology, strength and limitations of the studies were reviewed. CONCLUSIONS: Non-pharmacological interventions seem to have an important effect on weight gain prevention and control, and should be encouraged and adapted to patients and in mental health institution's reality.INTRODUÇÃO: Pacientes com esquizofrenia têm maior prevalência de obesidade em comparação à população geral. Esse fato está relacionado a uma alimentação inadequada, ao sedentarismo e ao uso de antipsicóticos. O aumento da obesidade associa-se a diversos distúrbios metabólicos, como o diabetes melito. As intervenções para prevenção e controle do ganho de peso são necessárias nessa população, em especial as intervenções não farmacológicas. OBJETIVO: Revisar os estudos sobre intervenções não farmacológicas para prevenção e controle do ganho de peso em pacientes com esquizofrenia. MÉTODOS: Foram encontrados oito estudos controlados e quatro não controlados sobre intervenções não farmacológicas. Foi feita uma revisãosobre a metodologia e os fatores positivos e limitações dos estudos. CONCLUSÕES: As intervenções não farmacológicas parecem ter um efeito importante em termos de prevenção e controle do ganho de peso e, portanto, devem ser incentivadas e adaptadas à realidade dos pacientes e serviços de saúde., Universidade Federal de São Paulo (UNIFESP) Departamento de PsiquiatriaUNIFESP Disciplina de Endocrinologia Departamento de MedicinaUNIFESP, Depto. de PsiquiatriaUNIFESP, Disciplina de Endocrinologia Depto. de MedicinaSciEL

Astrocytes grown in Alvetex® 3 dimensional scaffolds retain a non-reactive phenotype

yesProtocols which permit the extraction of primary astrocytes from either embryonic or postnatal mice are well established however astrocytes in culture are different to those in the mature CNS. Three dimensional (3D) cultures, using a variety of scaffolds may enable better phenotypic properties to be developed in culture. We present data from embryonic (E15) and postnatal (P4) murine primary cortical astrocytes grown on coated coverslips or a 3D polystyrene scaffold, Alvetex. Growth of both embryonic and postnatal primary astrocytes in the 3D scaffold changed astrocyte morphology to a mature, protoplasmic phenotype. Embryonic-derived astrocytes in 3D expressed markers of mature astrocytes, namely the glutamate transporter GLT-1 with low levels of the chondroitin sulphate proteoglycans, NG2 and SMC3. Embroynic astrocytes derived in 3D show lower levels of markers of reactive astrocytes, namely GFAP and mRNA levels of LCN2, PTX3, Serpina3n and Cx43. Postnatal-derived astrocytes show few protein changes between 2D and 3D conditions. Our data shows that Alvetex is a suitable scaffold for growth of astrocytes, and with appropriate choice of cells allows the maintenance of astrocytes with the properties of mature cells and a non-reactive phenotype.BBSR

QCD and strongly coupled gauge theories : challenges and perspectives

We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as to searches for physics beyond the Standard Model. We also discuss how success in describing the strong interaction impacts other fields, and, in turn, how such subjects can impact studies of the strong interaction. In the course of the work we offer a perspective on the many research streams which flow into and out of QCD, as well as a vision for future developments.Peer reviewe
