Since its first successful performance in 1945, haemodialysis has become a widely performed routine and safe procedure. However, despite significant improvements in the dialysis equipment, staff training, and patient monitoring, acute complications can occur during the therapy, ranging from mild to life-threatening. This chapter reviews selected acute complications that are encountered during or are directly related to the haemodialysis procedure, including cardiovascular, neuromuscular, haematological, and pulmonary complications, technical malfunctions, dialysis reactions (including anaphylactic and anaphylactoid reactions), and other complications such as post-dialysis fatigue, pruritus, priapism, and hearing and visual loss.

Maximal intensity is any activity where the exercise-supplying metabolism demonstrates a higher anaerobic ATP yield than the oxidative phosphorylation metabolism. Ethical considerations prevent muscle biopsy techniques in young people, resulting in indirect inferences about anaerobic metabolism during exercise being applied to mostly mechanically derived measurements. These measurements are largely based on cycle ergometry tests like the Wingate test. Compared to aerobic data, maximal-intensity data sets are infrequently published, female data across all age ranges are lacking, and application is limited by a focus on sports performance rather than health. However, regardless of how these data are analysed, children and adolescent performance is inferior to adults. Most studies attempt to explain this from a quantitative muscle (and age) perspective, while explanations of qualitative factors, e.g. hormonal and neuromuscular, have proved elusive. Future studies should focus on the mechanisms underpinning maximal-intensity exercise as an important component of everyday physical activity.

Dyspnoea may be defined as a subjective experience of discomfort associated with breathing. Breathing discomfort arises as a result of complex interactions between signals relayed from the upper airways, the chest wall, the lungs, and the central nervous system. Integration of this information with higher brain centres provides further processing. The final aspects of the sensation of dyspnoea are influenced by contextual, environmental, behavioural, and cognitive factors. At least three qualitatively distinct sensations have been employed to describe discomfort in breathing—air hunger, increased effort of breathing, and chest tightness. Air hunger has been shown to be associated with stimulation of chemoreceptors. Increased effort of breathing may arise in clinical conditions that impair respiratory muscle performance through abnormal mechanical loads or when respiratory muscles are weakened (neuromuscular diseases). Chest tightness is often experienced by asthmatic patients during episodes of acute bronchoconstriction. Measurement of dyspnoea is essential in order to assess it adequately and monitor response to treatment. Dyspnoea assessment may be carried out thorough a number of different scales, questionnaires, or exercise tests. Strategies in controlling dyspnoea should not focus uniquely on decreasing dyspnoea intensity. Patients may profit from interventions that decrease the unpleasantness associated with breathlessness without necessarily affecting the intensity component of the symptom.

The Western approach to dance is largely focused on control and mastery of technique, both of which are certainly necessary skills for improving performance. But mindful attention, despite its critical role in high performance, has gotten short shrift—until now. Attention and Focus in Dance, a how-to book rooted in the 20 years of attentional focus findings of researcher Gabriele Wulf, will help dancers unlock their power and stamina reserves, enabling efficient movement, heightening their sensory perception and releasing their dance potential. Author Clare Guss-West—a professional dancer, choreographer, teacher and holistic practitioner—presents a systematic, science-based approach to the mental work of dance. Her approach helps dancers hone the skills of attention, focus and self-cueing to replenish energy and enhance their physical and artistic performance. A Unique, Research-Based Approach Here is what Attention and Focus in Dance offers readers: • A unique approach, connecting the foundations of Eastern movement with Western movement forms • Research-based teaching practices in diverse contexts, including professional dance companies, private studios, and programmes for dancers with special needs or movement challenges • Testimonies and tips from international professional dancers and dance educators who use the book's approach in their training and teaching • A dance-centric focus that can be easily integrated into existing training and teaching practice, in rehearsal, or in rehabilitation contexts to provide immediate and long-term benefits Guss-West explores attentional focus techniques for dancers, teachers and dance health care practitioners, making practical connections between research, movement theory and day-to-day dance practice. “Many dancers are using excessive energy deployment and significant counterproductive effort, and that can lead to a global movement dysfunction, lack of stamina and an increased risk of injury,” says Guss-West. “Attentional focus training is the most relevant study that sport science and Eastern-movement practice can bring to dance.” Book Organisation The text is organised into two parts. Part I guides dancers in looking at the attentional challenges and information overload that many professional dancers suffer from. It outlines the need for a systematic attention and focus strategy, and it explains how scientific research on attentional focus relates to dance practice. This part also examines the ways in which Eastern-movement principles intersect with and complement scientific findings, and it examines how the Eastern and scientific concepts can breathe new life into basic dance elements such as posture, turnout and port de bras. Attention and focus techniques are included for replenishing energy and protecting against energy depletion and exhaustion. Part II presents attention and focus strategies for teaching, self-coaching and cueing. It addresses attentional focus cues for beginners and for more advanced dancers and professionals, and it places attentional focus in the broader context of holistic teaching strategies. Maximising Dance Potential “Whether cueing others or yourself, cueing for high performance is an art,” Guss-West says. “Readers will discover how to format cues and feedback to facilitate effective neuromuscular response and enhance dancer recall of information and accessibility while dancing.” Attention and Focus in Dance offers an abundance of research-backed concepts and inspirational ideas that can help dancers in their learning and performance. This book aids readers in filtering information and directing their focus for optimal physical effect. Ultimately, it guides dancers and teachers in being the best version of themselves and maximising their potential in dance.
