A randomized controlled trial evaluating Mindfulness-Based Stress Reduction (MBSR) for the treatment of palpitations: A pilot study

Biobehavioral approach to distinguishing panic symptoms from medical illness

Panic disorder is a common psychiatric diagnosis characterized by acute, distressing somatic symptoms that mimic medically-relevant symptoms. As a result, individuals with panic disorder overutilize personal and healthcare resources in an attempt to diagnose and treat physical symptoms that are often medically benign. A biobehavioral perspective on these symptoms is needed that integrates psychological and medical knowledge to avoid costly treatments and prolonged suffering. This narrative review examines six common somatic symptoms of panic attacks (non-cardiac chest pain, palpitations, dyspnea, dizziness, abdominal distress, and paresthesia), identified in the literature as the most severe, prevalent, or critical for differential diagnosis in somatic illness, including long COVID. We review somatic illnesses that are commonly comorbid or produce panic-like symptoms, their relevant risk factors, characteristics that assist in distinguishing them from panic, and treatment approaches that are typical for these conditions. Additionally, this review discusses key factors, including cultural considerations, to assist healthcare professionals in differentiating benign from medically relevant symptoms in panic sufferers.

[Making the Link - An Integrative Access to Somatic Syndrome Disorder]

Making the Link - An Integrative Access to Somatic Syndrome Disorder Abstract. The concept of somatic stress disorders published in 2013 in the DSM-V allows a paradigm shift in the treatment of patients with chronic physical symptoms. The earlier dualistic classification into purely psychogenic or purely physical causes gives way to an overarching bio-psycho-social understanding with the inclusion of modern scientific findings. This promotes an open attitude towards the subjective feelings, values and ideas of the patient, patient-oriented communication and the trusting doctor-patient relationship that is essential for the course of the disease. Integrative medicine offers a suitable framework for this.

The Effects of Mindfulness and Meditation on Vagally Mediated Heart Rate Variability: A Meta-Analysis

OBJECTIVE

Heart rate variability (HRV) is a marker of autonomic nervous system function associated with both physical and mental health. Many studies have suggested that mindfulness and meditation-based interventions (MBIs) are associated with improvements in HRV, but findings are mixed, and to date, no comprehensive meta-analysis has synthesized results.

METHODS

Systematic literature searches were conducted using PsycINFO, Embase, Medline, CINAHL, ERIC, and Scopus to identify randomized controlled trials (RCTs) investigating the effects of predominantly seated MBIs on resting-state vagally mediated HRV. Risk of bias was judged using the Cochrane Risk of Bias tool.

RESULTS

Nineteen RCTs met the criteria for inclusion in the meta-analysis. Random-effects meta-analysis found that MBIs were not efficacious in increasing vagally mediated resting-state HRV relative to control conditions (Hedges g = 0.38, 95% confidence interval [CI] = -0.014 to 0.77). When removing an outlier (g = 3.22), the effect size was reduced, CI narrowed, and findings remained nonsignificant (g = 0.19, 95% CI = -0.02 to 0.39). High heterogeneity in results (I2 = 89.12%) could not be explained by a priori-determined moderators including intervention duration, study setting, and control type.

CONCLUSIONS

There is currently insufficient evidence to indicate that MBIs lead to improvements in vagally mediated HRV over control conditions. Future large, well-designed RCTs with low risk of methodological bias could help add to the current evidence to elucidate any role MBIs might play in impacting HRV.

Mindfulness-Based Interventions for Physical and Psychological Wellbeing in Cardiovascular Diseases: A Systematic Review and Meta-Analysis

BACKGROUND

Recently, there has been an increased interest in the efficacy of mindfulness-based interventions (MBI) for people with cardiovascular diseases (CVD), although the exact beneficial effects remain unclear.

METHODS

This review aims to establish the role of MBI in the management of wellbeing for patients with CVD. Seventeen articles have been included in this systematic synthesis of the literature and eleven in the meta-analysis.

RESULTS

Considering physical (i.e., heart rate, blood pressure) and psychological outcomes (i.e., depression, anxiety, stress, styles of coping), the vast majority of studies confirmed that MBI has a positive influence on coping with psychological risk factors, also improving physiological fitness. Random-effects meta-analysis models suggested a moderate-to-large effect size in reducing anxiety, depression, stress, and systolic blood pressure.

CONCLUSIONS

Although a high heterogeneity was observed in the methodological approaches, scientific literature confirmed that MBI can now be translated into a first-line intervention tool for improving physical and psychological wellbeing in CVD patients.

Effects of mindfulness training on posttraumatic stress symptoms from a community-based pilot clinical trial among survivors of intimate partner violence

Objective: Exposure to intimate partner violence (IPV) is a significant public health issue associated with deleterious mental and medical health comorbidities, including posttraumatic stress disorder (PTSD). The hallmark symptoms of posttraumatic stress (PTS), even when not meeting the threshold for a diagnosis of PTSD, appear to be underpinned by poor self-regulation in multiple domains, including emotion, cognitive control, and physiological stress. Mindfulness-based stress reduction (MBSR) holds promise for treating PTS symptoms because evidence suggests it targets these domains. The current study was a pilot randomized clinical trial designed to examine changes in emotion regulation, attentional function, and physiological stress dysregulation among women IPV survivors with elevated PTS symptoms after participation in a group-based, 8-week MBSR program. Method: In total, 29 participants were randomized to receive MBSR (n = 19) or an active control (n = 10). Assessments were conducted at study entry, as well as 8 and 12 weeks later. Results: Between-group differences on primary outcomes were nonsignificant; however, when exploring within groups, statistically significant decreases in PTS symptoms, F(1.37, 16.53) = 5.19, p < .05, and emotion dysregulation, F(1.31, 14.46) = 9.36, p < .01, were observed after MBSR but not after the control intervention. Further, decreases in PTSD and emotion dysregulation were clinically significant for MBSR participants but not control participants. Conclusions: These preliminary data signal that MBSR may improve PTS symptoms and emotion regulation and suggest further study of the effectiveness of PTSD interventions guided by integrative models of MBSR mechanisms and psychophysiological models of stress regulation.

A Systematic Review and Meta-Analysis of the Impact of Mindfulness Based Interventions on Heart Rate Variability and Inflammatory Markers

Mindfulness Based Interventions (MBIs) have recently been increasingly used in clinical settings, and research regarding their effects on health has grown rapidly. However, with regard to the physiological effects of mindfulness practices, studies have reported associations that vary in strength and direction. Therefore, in this systematic review and meta-analysis, we aimed to systematically identify, appraise, and summarize the existing data from randomized and non-randomized controlled trials that examine physiological effects of the standardized MBIs by focusing on pro-inflammatory cytokines and C-reactive protein, and commonly used heart rate variability parameters. The following electronic databases were searched: MEDLINE (via Ovid), PsychINFO (via Ovid), PubMed, Web of Science, EMBASE, CINAHL, ProQuest (Dissertations and Theses), and ClinicalTrails.gov. The systematic review identified 10 studies to be included in the meta-analysis, comprising in total 607 participants. The meta-analysis ended up with mixed and inconclusive results. This was assumedly due to the small number of the original studies and, in particular, to the lack of large, rigorously conducted RCTs. Therefore, the current meta-analysis highlights the necessity of larger, more rigorously conducted RCTs on physiological outcomes with standardized MBIs being compared to various forms of active controls, and with more long-term follow-ups.

A mindfulness intervention to reduce maternal distress in neonatal intensive care: a mixed methods pilot study

Mothers with an infant in the neonatal intensive care unit (NICU) are at risk for depression, anxiety, and trauma symptoms, with negative implications for maternal-infant bonding, maternal well-being, and infant development. Few interventions to promote NICU mothers' mental health, however, have been developed or tested. This pre-post pilot study assessed feasibility, acceptability, and preliminary outcomes of a mindfulness intervention for NICU mothers. Twenty-seven mothers were recruited from a university NICU and offered a mindfulness intervention via introductory video and audio-recorded practices. Participants completed a baseline self-report survey. After 2 weeks of engaging with intervention materials, participants completed a second survey and in-depth interview. Quantitative data were analyzed using paired t tests; qualitative data were analyzed using thematic coding. Twenty-four women (89%) completed the study. Quantitative data indicated significant improvements in depressive, anxiety, and trauma symptoms, negative coping, NICU-related stress, and sleep (p < 0.05). Qualitative data identified themes of perceived improvements in psychological distress and stress symptoms, self-care, and relationships. Findings support the mindfulness intervention's feasibility, acceptability, and potential promise for reducing maternal distress and promoting well-being. Use of video and audio modalities may facilitate program sustainability and scale up. Further research on the program is merited.

Accessibility and feasibility of using technology to support mindfulness practice, reduce stress and promote long term mental health

BACKGROUND AND PURPOSE

We evaluated the feasibility of using an activity monitor to support mindfulness practice, reduce self-reported stress and physiological indicators of stress.

MATERIALS AND METHODS

Adult women (N = 19) who previously participated in a mindfulness intervention wore an activity monitor for eight-weeks. The activity monitor notified them when they were stressed (based on standard deviation pulse pressure). Heart rate and pulse pressure were continuously collected via the activity monitor. Mindfulness, stress, depression and trauma symptoms were collected via self-report surveys.

RESULTS

There were no significant changes in self-reported stress, depression, post-traumatic stress and mindfulness from baseline to eight-weeks. Pulse pressure and standard deviation of pulse pressure increased over time. Those who were high on the non-judge mindfulness subscale had a lower standard deviation pulse pressure and spent less time stressed.

CONCLUSION

Those who are more mindful are less likely to have physiological signs of stress.
