Mindfulness may both moderate and mediate the effect of physical fitness on cardiovascular responses to stress: a speculative hypothesis

Practical Strategies for Identifying and Managing Burnout in Plastic Surgeons

BACKGROUND

Physician burnout is a well-known problem and widespread issue in the field of medicine. Recently, more attention has been given to the significance of burnout among plastic surgeons. The cause of burnout is multifactorial, with emotional exhaustion, depersonalization, and a reduced sense of personal accomplishment all playing a role. The objective of this article is to provide practical measures to help plastic surgeons in identifying the signs of burnout, thereby mitigating its consequences.

METHODS

A literature review was performed to determine the comprehensive findings of previous research conducted on burnout among plastic surgeons. Particular interest was given to successful tactics used in managing work-related stress. Wellness strategies and resources from both academic and private medical settings were also obtained to further review methods for burnout management.

RESULTS

There is a wide range of causes and risk factors for burnout among plastic surgeons. The majority of cases correlate with increased workload, loss of physician autonomy, and, in the context of trainees, lack of mentorship. Managing burnout can be supported by identification through survey tools. Establishing a wellness committee is also useful to develop institution-specific interventions. Equally as important, individuals must take steps to manage and minimize their burnout.

CONCLUSIONS

This article provides practical strategies for institutions to identify and manage burnout among plastic surgeons. It is obvious that causes of burnout vary in different settings such as academic and community hospitals; therefore, it is critical for institutions to individualize their approach to burnout.

Mindfulness versus Physical Exercise: Effects of Two Recovery Strategies on Mental Health, Stress and Immunoglobulin A during Lunch Breaks. A Randomized Controlled Trial

This research analyses the effects of mindfulness meditation (MM) and physical exercise (PE), practised as daily recovery activities during lunch breaks, on perceived stress, general mental health, and immunoglobin A (IgA). A three-armed randomized controlled trial with 94 employees was conducted for five weeks including two follow-up sessions after one and six months. Daily practice lasted 30 min maximum. Perceived stress and general mental health questionnaires and saliva samples were used. There were significant differences in time factor comparing pre- and post-test of Perceived Stress Questionnaire (PSQ) both for PE [Mdiff = 0.10, SE = 0.03, p = 0.03], and for MM [Mdiff = 0.09, SE = 0.03, p = 0.03]. Moreover, there were significant differences of interaction factor when comparing MM vs. PE in total score at pre-post [F = −2.62 (6, 168.84), p = 0.02, ω² = 0.09], favoring PE with medium and high effect sizes. Regarding General Health Questionnaire (GHQ) variable, practicing MM showed significant effects in time factor compared to pre-Fup2. No significant differences were found for IgA. Thus, practicing both MM and PE as recovery strategies during lunch breaks could reduce perceived stress after five weeks of practice, with better results for PE. Moreover, practicing MM could improve mental health with effects for 6 months.

Exploring the Use of Meditation as a Valuable Tool to Counteract Sedentariness

Some forms of meditation have been recently proposed as effective tools to facilitate the handling of undesired thoughts and reappraisal of negative emotions that commonly arise during exercise-related situations. The effects of meditation-based interventions on psychological responses could also be used as a means by which to increase exercise adherence and counteract the detrimental consequences of sedentariness. In the present article, we briefly describe the effects of meditation on physical activity and related factors. We also propose a theoretical model as a means by which to further understanding of the effects of meditation on psychological, psychophysical, and psychophysiological responses during exercise. The results of very recent studies in the realms of cognitive and affective psychology are promising. The putative psychological mechanisms underlying the effects of meditation on exercise appear to be associated with the interpretation of interoceptive and exteroceptive sensory signals. This is primarily due to the fact that meditation influences the cerebral processing of physical sensations, emotions, and thoughts. In such instances, the bodily and perceptual responses that are commonly reported during exercise might be assuaged during the practice of meditation. It also appears that conscious presence and self-compassion function as an emotional backdrop against which more complex behaviors can be forged. In such instances, re-engagement to physical activity programs can be more effectively achieved through the implementation of holistic methods to treat the body and mind. The comments provided in the present paper might have very important implications for exercise adherence and the treatment of hypokinetic diseases.

Effects of mindfulness on psychological and psychophysiological responses during self-paced walking

The aim of the present study was to investigate the effects of an audio-guided mindfulness (MF) single session on psychological and psychophysiological responses during an outdoor walking task. Twenty-four participants (12 females and 12 males; M_age  = 23.6, SD = 3.9 years) were required to walk 200 m at a pace of their choosing. Two experimental conditions (mindfulness meditation and mindlessness [ML] meditation) and a control condition (CO) were administered. Electrical activity in the brain was measured by the use of a portable electroencephalography (EEG) system during walking. Fast Fourier Transform was used to decompose the EEG samples into theta (5-7 Hz), alpha (8-14 Hz), and beta (15-29 Hz) frequencies. Brain connectivity analysis between frontal and temporo-parietal electrode sites was conducted to explore functional interactions through the use of spectral coherence. Affective and perceptual responses were measured by the use of single-item scales and questionnaires. The present findings indicate that MF was sufficiently potent to reallocate attention toward task-related thoughts, downregulate perceived activation, and enhance affective responses to a greater degree than the other two conditions. Conversely, ML was sufficient to increase the use of dissociative thoughts, make participants less aware of their physical sensations and emotions, induce a more negative affective state, and upregulate perceived activation to a greater extent than MF and CO. The brain mechanisms that underlie the effects of MF on exercise appear to be associated with the enhanced inter-hemispheric connectivity of high-frequency waves between right frontal and left temporo-parietal areas of the cortex.

Mediational pathways of meditation and exercise on mental health and perceived stress: A randomized controlled trial

This study investigated the effects of mindfulness and exercise training on indicators of mental health and stress by examining shared mediators of program effects. Community-recruited adults (N = 413) were randomized into one of three conditions: (a) mindfulness-based stress reduction, (b) moderate intensity exercise, or (c) wait-list control. Composite indicator structural equation models estimated direct, indirect, and total effects. Results showed that mindfulness-based self-efficacy fulfilled a prominent role in mediating meditation and exercise program effects. Findings suggest that mindfulness and exercise training share similar mechanisms that can improve global mental health, including adaptive responses to stress.

Periodization Theory: Confronting an Inconvenient Truth

Periodization theory has, over the past seven decades, emerged as the preeminent training planning paradigm. The philosophical underpinnings of periodization theory can be traced back to the integration of diverse shaping influences, whereby coaching beliefs and traditions were blended with historically available scientific insights and contextualized against pervading social planning models. Since then, many dimensions of elite preparation have evolved significantly, as driven by a combination of coaching innovations and science-led advances in training theory, techniques, and technologies. These advances have been incorporated into the fabric of the pre-existing periodization planning framework, yet the philosophical assumptions underpinning periodization remain largely unchallenged and unchanged. One particularly influential academic sphere of study, the science of stress, particularly the work of Hans Selye, is repeatedly cited by theorists as a central pillar upon which periodization theory is founded. A fundamental assumption emanating from the early stress research is that physical stress is primarily a biologically mediated phenomenon: a presumption translated to athletic performance contexts as evidence that mechanical training stress directly regulates the magnitude of subsequent 'fitness' adaptations. Interestingly, however, since periodization theory first emerged, the science of stress has evolved extensively from its historical roots. This raises a fundamental question: if the original scientific platform upon which periodization theory was founded has disintegrated, should we critically re-evaluate conventional perspectives through an updated conceptual lens? Realigning periodization philosophy with contemporary stress theory thus presents us with an opportunity to recalibrate training planning models with both contemporary scientific insight and progressive coaching practice.

Physical Fitness Levels Do Not Affect Stress Levels in a Sample of Norwegian Adolescents

Physical inactivity, low physical fitness, and perceived stress during adolescence are presumed to be risk factors for various disorders and subjective health complaints. On the other hand, physical activity and physical fitness, as well as mindfulness qualities, are regarded as prerequisites for health and well-being in children and adolescent, possibly by moderating the negative effects of stress and protecting against stress-related health complaints. Previous studies have suggested gender differences in the relationship between physical activity/physical fitness and psychological variables. The main objective in this study was to evaluate how physical fitness, along with mindfulness qualities (MAAS-A), pain, and BMI, relate to stress (PSQ) in adolescents. Secondary objectives were to explore the relationship between physical fitness, mindfulness (MAAS-A), and BMI more explicitly in the study sample, as well as to evaluate possible gender differences. The cross-sectional sample included 102 Norwegian pupils in 10th grade (15 or 16 years). Study measurements were four items from the Test of Physical Fitness (TPF), the Norwegian version of the four-factor Perceived Stress Questionnaire (PSQ), the Norwegian version of the Mindful Attention Awareness Scale-Adolescent (MAAS-A), and BMI (recorded in terms of self-reported height and weight). Additionally, pain was measured in terms of localization, number of pain sites, duration, and intensity (Visual analogue scale; VAS). According to the regression analyses, physical fitness could not explain any variation in stress among the adolescents. Nevertheless, there were some negative associations between one stress factor (lack of joy) and components of physical fitness at a group level, possibly influenced by conditions not measured in this study. As opposed to physical fitness, mindfulness qualities, and to some degree gender, seemed to explain variation in stress among the adolescents. None of the physical fitness components were associated to mindfulness (MAAS-A), but some components seemed negatively related to BMI, particularly among the males. Among the females, higher physical fitness (in terms of endurance) seemed related to reduced number of pain sites. Of note, the cross-sectional design did not allow us to determine any causal direction among the variables.

Consumer Neuroscience-Based Metrics Predict Recall, Liking and Viewing Rates in Online Advertising

The purpose of the present study is to investigate whether the effectiveness of a new ad on digital channels (YouTube) can be predicted by using neural networks and neuroscience-based metrics (brain response, heart rate variability and eye tracking). Neurophysiological records from 35 participants were exposed to 8 relevant TV Super Bowl commercials. Correlations between neurophysiological-based metrics, ad recall, ad liking, the ACE metrix score and the number of views on YouTube during a year were investigated. Our findings suggest a significant correlation between neuroscience metrics and self-reported of ad effectiveness and the direct number of views on the YouTube channel. In addition, and using an artificial neural network based on neuroscience metrics, the model classifies (82.9% of average accuracy) and estimate the number of online views (mean error of 0.199). The results highlight the validity of neuromarketing-based techniques for predicting the success of advertising responses. Practitioners can consider the proposed methodology at the design stages of advertising content, thus enhancing advertising effectiveness. The study pioneers the use of neurophysiological methods in predicting advertising success in a digital context. This is the first article that has examined whether these measures could actually be used for predicting views for advertising on YouTube.

Quality of life improvement with rehabilitation according to constitution of the World Health Organization for coronary artery bypass graft surgery patients: A descriptive review

This is a descriptive review focusing on trends of treatments required for postoperative coronary artery bypass graft surgery (CABG) patients to improve the quality of life (QOL).

METHODOLOGY

The sources of literary research to understand the concepts of coronary artery disease according to Indian scriptures are Ayurveda texts, Bhagavad Gita, Patanjali Yoga Sutra. The data was typed in Sanskrit using Devanagari script and explanation in English was given. As per new research techniques, surgery, physiotherapy rehabilitation and Yoga are serving CABG patient's medical and psychological health better. The World Health Organization (WHO) defines health as physical, mental and social well-being later redefined with additional terms like environmental and spiritual health. This definition is similar to the Panchakosha concept in Yoga and Pancha Mahabhutas in Ayurveda. In cases of emergency or passive treatment, medication serves as a better option for physical health. In circumstances where the person is able to move in daily activities (just after discharge), rehabilitation serves as a better option for physical, mental and social health. Travel and reactions to climatic change serve environmental health. Last strategy, belief, cultural and traditional methods with scientific background serves as the spiritual health. These step-wise treatments are required for CABG patients to get the overall health or QOL. However, surgery and physiotherapy rehabilitation are advanced as per modern era which serves physical, mental, and social health also, but environmental health and spiritual health have yet to be addressed. As an ancient system of medicine, Yoga combines physical, mental, social, environmental and spiritual practices and it should be added as treatment along with surgery and physiotherapy rehabilitation. If all of these therapies were in the treatment protocol for CABG surgery patients, we would observe the changes of QOL and fulfill the requirements of constitution of the WHO. Integrating concepts of Yoga, Ayurveda, modern rehabilitation, surgery and patient cooperation with lifestyle change are the key to QOL improvements after CABG.

Mindfulness, Resilience, and Burnout Subtypes in Primary Care Physicians: The Possible Mediating Role of Positive and Negative Affect

Purpose: Primary care health professionals suffer from high levels of burnout. The aim of the present study was to evaluate the associations of mindfulness and resilience with the features of the burnout types (overload, lack of development, neglect) in primary care physicians, taking into account the potential mediating role of negative and positive affect.

Methods: A cross-sectional design was used. Six hundred and twenty-two Spanish primary care physicians were recruited from an online survey. The Mindful Attention Awareness Scale (MAAS), Connor-Davidson Resilience Scale (CD-RISC), Positive and Negative Affect Schedule (PANAS), and Burnout Clinical Subtype Questionnaire (BCSQ-12) questionnaires were administered. Polychoric correlation matrices were calculated. The unweighted least squares (ULS) method was used for developing structural equation modeling.

Results: Mindfulness and resilience presented moderately high associations (φ = 0.46). Links were found between mindfulness and overload (γ = −0.25); resilience and neglect (γ = −0.44); mindfulness and resilience, and negative affect (γ = −0.30 and γ = −0.35, respectively); resilience and positive affect (γ = 0.70); negative affect and overload (β = 0.36); positive affect and lack of development (β = −0.16). The links between the burnout types reached high and positive values between overload and lack of development (β = 0.64), and lack of development and neglect (β = 0.52). The model was a very good fit to the data (GFI = 0.96; AGFI = 0.96; RMSR = 0.06; NFI = 0.95; RFI = 0.95; PRATIO = 0.96).

Conclusions: Interventions addressing both mindfulness and resilience can influence burnout subtypes, but their impact may occur in different ways, potentially mediated by positive and negative affect. Both sorts of trainings could constitute possible tools against burnout; however, while mindfulness seems a suitable intervention for preventing its initial stages, resilience may be more effective for treating its advanced stages.

Effects of exercise training on stress-induced vascular reactivity alterations: role of nitric oxide and prostanoids

BACKGROUND

Physical exercise may modify biologic stress responses.

OBJECTIVE

To investigate the impact of exercise training on vascular alterations induced by acute stress, focusing on nitric oxide and cyclooxygenase pathways.

METHOD

Wistar rats were separated into: sedentary, trained (60-min swimming, 5 days/week during 8 weeks, carrying a 5% body-weight load), stressed (2 h-immobilization), and trained/stressed. Response curves for noradrenaline, in the absence and presence of L-NAME or indomethacin, were obtained in intact and denuded aortas (n = 7-10).

RESULTS

None of the procedures altered the denuded aorta reactivity. Intact aortas from stressed, trained, and trained/stressed rats showed similar reduction in noradrenaline maximal responses (sedentary 3.54 ± 0.15, stressed 2.80 ± 0.10*, trained 2.82 ± 0.11*, trained/stressed 2.97 ± 0.21*, *P < 0.05 relate to sedentary). Endothelium removal and L-NAME abolished this hyporeactivity in all experimental groups, except in trained/stressed rats that showed a partial aorta reactivity recovery in L-NAME presence (L-NAME: sedentary 5.23 ± 0,26#, stressed 5.55 ± 0.38#, trained 5.28 ± 0.30#, trained/stressed 4.42 ± 0.41, #P < 0.05 related to trained/stressed). Indomethacin determined a decrease in sensitivity (EC50) in intact aortas of trained rats without abolishing the aortal hyporeactivity in trained, stressed, and trained/stressed rats.

CONCLUSIONS

Exercise-induced vascular adaptive response involved an increase in endothelial vasodilator prostaglandins and nitric oxide. Stress-induced vascular adaptive response involved an increase in endothelial nitric oxide. Beside the involvement of the endothelial nitric oxide pathway, the vascular response of trained/stressed rats involved an additional mechanism yet to be elucidated. These findings advance on the understanding of the vascular processes after exercise and stress alone and in combination.

Mindfulness and Physical Activity

Mindfulness and mindful activity can have a profound effect on physical and mental health. When considering mindfulness and physical activity, it is important to differentiate between physical activities, which are geared toward mindfulness and have mindful components, for example, yoga, platies, and tai chi, from other mindfulness interventions that are then geared toward greater awareness and mindfulness, which may then lead to healthful behavior change such as increasing physical activity. Prescribing mindfulness interventions may be another resource to help physicians when interacting with their patients, considering motivating patients to exercise and become more physically active can be challenging. Engaging in mindfulness can elicit change over time. Integrating mindfulness to interventions with exercise is one way to initiate exercise adherence as well as improve self-efficacy. When practicing mindful-based exercise programs, the benefits can also be seen with improved breathing rate and depth, heart rate, and parasympathetic activity. Promoting mindfulness-based training for physical activity has positive effects both psychologically and physiologically.
