Effect of Mind Sound Resonance Technique (MSRT – A yoga-based relaxation technique) on psychological variables and cognition in school children: A randomized controlled trial

ObjectiveSchool children undergo stress, which could impact their psychological functions and cognitive abilities. Yoga practices have been found useful in enhancing psychological functions and performance. The current study was planned to evaluate a yoga-based relaxation technique's efficacy as an extracurricular activity on psychological state and cognitive function.Design and settingThis study was a parallel-group randomized controlled trial conducted at a government school in south India.ParticipantsSixty students with age ranging between 14–16 years (mean age ± SD; 15.3 ± 0.71 years) satisfying the inclusion and exclusion criteria were randomized to experimental and control groups with an allocation ratio of 1:1.InterventionExperimental group received Mind Sound Resonance Technique (MSRT), whereas the control group performed supine rest (SR) for two-weeks.Outcome measuresParticipants were assessed with State trait anxiety inventory - short form, Mind Wandering Questionnaire, State Mindfulness Attention Awareness Scale, and Trail making task at baseline and post-intervention.ResultsExperimental group showed a reduction in state anxiety and mind wandering with improvement in state mindfulness and performance in the Trail-making task compared to the control group.ConclusionResults of the current trial indicate the beneficial role of MSRT in enhancing psychological and cognitive functions in children. Further, large-scale trials are warranted to ascertain the usefulness of the technique.

Episodic memory: Neuronal codes for what,where, and when

Episodic memory is defined as the ability to recall events in a spatiotemporal context. Formation of such memories is critically dependent on the hippocampal formation and its inputs from the entorhinal cortex. To be able to support the formation of episodic memories, entorhinal cortex and hippocampal formation should contain a neuronal code that follows several requirements. First, the code should include information about position of the agent (“where”), sequence of events (“when”), and the content of the experience itself (“what”). Second, the code should arise instantly thereby being able to support memory formation of one‐shot experiences. For successful encoding and to avoid interference between memories during recall, variations in location, time, or in content of experience should result in unique ensemble activity. Finally, the code should capture several different resolutions of experience so that the necessary details relevant for future memory‐based predictions will be stored. We review how neuronal codes in entorhinal cortex and hippocampus follow these requirements and argue that during formation of episodic memories entorhinal cortex provides hippocampus with instant information about ongoing experience. Such information originates from (a) spatially modulated neurons in medial entorhinal cortex, including grid cells, which provide a stable and universal positional metric of the environment; (b) a continuously varying signal in lateral entorhinal cortex providing a code for the temporal progression of events; and (c) entorhinal neurons coding the content of experiences exemplified by object‐coding and odor‐selective neurons. During formation of episodic memories, information from these systems are thought to be encoded as unique sequential ensemble activity in hippocampus, thereby encoding associations between the content of an event and its spatial and temporal contexts. Upon exposure to parts of the encoded stimuli, activity in these ensembles can be reinstated, leading to reactivation of the encoded activity pattern and memory recollection.

Bringing Up the Bodies: Psyche–Soma,Body Awareness and Feeling At Ease

This paper looks at how difficult early experiences can give rise to defences in which patients rely excessively on their minds, or on bodily activity, having little faith in good reliable objects, internal or external, and little capacity for relaxation and just being. Links are made between Winnicott's theories about mind and psyche–soma and Porges' more recent ideas about vagal tone and the parasympathetic nervous system. These ideas are illustrated with a number of clinical examples of patients who were distrustful of others and who were out of touch with their bodily states. Attention is paid to the need to become more ‘body aware’ in our clinical technique, and questions are asked as to how we might manage this.

Utilizing Quality Improvement Methods to Examine the Radiation Therapy Pathway for Patients Requiring Palliative Radiation Therapy at a Community Cancer Center

BackgroundAt a community cancer center, during weekly quality improvement huddles, the radiation therapy team expressed stress and frustration with the pretreatment pathway for patients requiring palliative radiotherapy. As the department was meeting provincial targets with respect to wait times, it was unknown why the consensus around the department reflected discomfort and stress.MethodsFour radiation therapists formed a quality improvement project team, intent on utilizing a data-driven improvement cycle to investigate and address opportunities to improve the discomfort around this pretreatment pathway. After defining the process and identifying the customers (the health care providers operating in this pathway), the team conducted interviews with each person, transcribing answers verbatim, and grouping results by discipline. Utilizing the interview themes, each discipline identified one or two priorities to measure, as well as metrics to capture the magnitude and prevalence of these priorities.ResultsEach discipline's priorities were measured and analyzed. The identified issues brought forward at the weekly quality improvement huddles were not as prevalent as expected. Minor changes were implemented for priority issues.ConclusionThe team focused on the four principles of quality improvement: the patient, team, process, and data to address the expressed discomfort around this specific radiation therapy pathway. The results dispelled some of the myths among teams and provided solutions to areas where minor improvements were required. Utilizing the data, an evidence-informed timeline was validated, encouraging task deadlines to be more evenly distributed across the pathway. Plans to monitor this pathway are being established. The team was successful in contributing to a growing culture of continuous improvement at this community cancer center.
