Improving nurses' therapeutic attitude to patients who use illicit drugs: Workplace drug and alcohol education is not enough

Abstract: This study examines the impact of workplace drug and alcohol education on nurses' therapeutic attitude to patients who use illicit drugs. It builds on a study of the generalist nursing workforce in the Australian Capital Territory in 2003, which showed that the interaction of role support with workplace drug and alcohol education facilitated nurses' therapeutic attitude. This paper explores this interaction in detail, showing that workplace education has no independent association with therapeutic attitude and that an effect from education only occurs when nurses have at least a moderate level of role support. Nursing workforce development needs to focus on strategies that provide role support for nurses as they work with this clinically challenging patient group. Without the ready availability of someone in the nurse's clinical field to advise and assist them, efforts to increase nurses' knowledge and skills are wasted.

Combining self-management cues with incentives to promote interdental cleaning among Indian periodontal disease outpatients

Abstract: Periodontal disease is a significant public health issue worldwide. Motivational techniques in combination with financial incentives are shown to lead to effective behavior change. The current study sought to examine whether a brief oral health promotion program (self-management cues that were based on self-efficacy and self-regulatory skills) in combination with an incentive (free dental treatment) would make a difference in the adoption of regular dental flossing in a population of Indian periodontal disease outpatients.

Healthcare choice: Bourdieu’s capital, habitus and field

Abstract: The promotion of choice is a common theme in both policy discourses and commercial marketing claims about healthcare. However, within the multiple potential pathways of the healthcare ‘maze’, how do healthcare ‘consumers’ or patients understand and experience choice? What is meant by ‘choice’ in the policy context, and, importantly from a sociological perspective, how are such choices socially produced and structured? In this theoretical article, the authors consider the interplay of Bourdieu’s three key, interlinked concepts – capital, habitus and field – in the structuring of healthcare choice. These are offered as an alternative to rational choice theory, where ‘choice’ is regarded uncritically as a fundamental ‘good’ and able to provide a solution to the problems of the healthcare system. The authors argue that sociological analyses of healthcare choice must take greater account of the ‘field’ in which choices are made in order to better explain the structuring of choice.

Emotion Regulation Using Virtual Environments and Real-Time fMRI Neurofeedback

Abstract: Neurofeedback (NFB) enables the voluntary regulation of brain activity, with promising applications to enhance and recover emotion and cognitive processes, and their underlying neurobiology. It remains unclear whether NFB can be used to aid and sustain complex emotions, with ecological validity implications. We provide a technical proof of concept of a novel real-time functional magnetic resonance imaging (rtfMRI) NFB procedure. Using rtfMRI-NFB, we enabled participants to voluntarily enhance their own neural activity while they experienced complex emotions. The rtfMRI-NFB software (FRIEND Engine) was adapted to provide a virtual environment as brain computer interface (BCI) and musical excerpts to induce two emotions (tenderness and anguish), aided by participants' preferred personalized strategies to maximize the intensity of these emotions. Eight participants from two experimental sites performed rtfMRI-NFB on two consecutive days in a counterbalanced design. On one day, rtfMRI-NFB was delivered to participants using a region of interest (ROI) method, while on the other day using a support vector machine (SVM) classifier. Our multimodal VR/NFB approach was technically feasible and robust as a method for real-time measurement of the neural correlates of complex emotional states and their voluntary modulation. Guided by the color changes of the virtual environment BCI during rtfMRI-NFB, participants successfully increased in real time, the activity of the septo-hypothalamic area and the amygdala during the ROI based rtfMRI-NFB, and successfully evoked distributed patterns of brain activity classified as tenderness and anguish during SVM-based rtfMRI-NFB. Offline fMRI analyses confirmed that during tenderness rtfMRI-NFB conditions, participants recruited the septo-hypothalamic area and other regions ascribed to social affiliative emotions (medial frontal / temporal pole and precuneus). During anguish rtfMRI-NFB conditions, participants recruited the amygdala and other dorsolateral prefrontal and additional regions associated with negative affect. These findings were robust and were demonstrable at the individual subject level, and were reflected in self-reported emotion intensity during rtfMRI-NFB, being observed with both ROI and SVM methods and across the two sites. Our multimodal VR/rtfMRI-NFB protocol provides an engaging tool for brain-based interventions to enhance emotional states in healthy subjects and may find applications in clinical conditions associated with anxiety, stress and impaired empathy among others.

New approaches to determine fatigue in elite athletes during intensified training: Resting metabolic rate and pacing profile

Abstract: Background Elite rowers complete a high volume of training across a number of modalities to prepare for competition, including periods of intensified load, which may lead to fatigue and short-term performance decrements. As yet, the influence of substantial fatigue on resting metabolic rate (RMR) and exercise regulation (pacing), and their subsequent utility as monitoring parameters, has not been explicitly investigated in elite endurance athletes. Method Ten National-level rowers completed a four-week period of intensified training. RMR, body composition and energy intake were assessed PRE and POST the four-week period using indirect calorimetry, Dual-Energy X-Ray Densitometry (DXA), and three-day food diary, respectively. On-water rowing performance and pacing strategy was evaluated from 5 km time trials. Wellness was assessed weekly using the Multicomponent Training Distress Scale (MTDS). Results Significant decreases in absolute (mean ± SD of difference, p-value: -466 ± 488 kJ.day-1, p = 0.01) and relative RMR (-8.0 ± 8.1 kJ.kg.FFM-1, p = 0.01) were observed. Significant reductions in body mass (-1.6 ± 1.3 kg, p = 0.003) and fat mass (-2.2 ± 1.2 kg, p = 0.0001) were detected, while energy intake was unchanged. On-water 5 km rowing performance worsened (p < 0.05) and an altered pacing strategy was evident. Fatigue and total mood disturbance significantly increased across the cycle (p < 0.05), and trends were observed for reduced vigour and increased sleep disturbance (p < 0.1). Conclusion Four weeks of heavy training decreased RMR and body composition variables in elite rowers and induced substantial fatigue, likely related to an imbalance between energy intake and output. This study demonstrates that highly experienced athletes do not necessarily select the correct energy intake during periods of intensified training, and this can be assessed by reductions in RMR and body composition. The shortfall in energy availability likely affected recovery from training and altered 5 km time trial pacing strategy, resulting in reduced performance.
