    Benson's relaxation affects many symptoms among hemodialysis patients. A cluster-randomized active control clinical trial with three repeated measures; pre, 1-week, and 1-month post-intervention sought to evaluate the effectiveness of Benson's Relaxation on pain and perceived stress (P&PS) among hemodialysis patients. Two governmental hospitals were randomly assigned to intervention and control. Thirty-six participants were randomly selected; 18 were intervention, and 18 were controlled. The intervention group performed Benson's Relaxation twice a day for 10 minutes for 8 weeks after a training session. The control group received an educational session about Progressive Relaxation. Findings revealed a statistically significant reduction in the PSS-10 and PRI scores between pre-intervention and 1 month after-intervention (p  .05). Benson's Relaxation significantly relieved P&PS among hemodialysis patients but not after only 1 week of practicing.

    In psychiatry, mindfulness based intervention has been increasingly popular as a means of psychosocial intervention over the last decade. With the alvanche of technological advances, there has been a myriad of mindfulness based applications. Recent reviews have highlighted how these applications are lacking in functionalities and without demonstrated efficacy. Other reviews have emphasized that there is a need to take into consideration the design of an application, due to placebo effects. It is the aim of this technical note to illustrate how the 5-Minutes Mindfulness application, which is an application designed to provide mindfulness exercises to relieve distress and suffering amongst palliative patients, have been conceptualized. The conceptualized application builds on previous evidence of the efficacy of 5-Minutes Mindfulness demonstrated by pilot and randomized trials. In terms of design, the currently conceptualized application has been designed such that placebo effects could be controlled for.

    BACKGROUND: We investigated the efficacy of mindfulness-based intervention (MBI) in promoting psychological wellbeing in people with epilepsy (PWE) using an assessor-blinded randomized controlled design.

    METHODS: A total of 28 PWE were randomly assigned to either intervention (n = 14 cases) or control group (n = 14 controls). The intervention group received a six 2.5-hour weekly MBI, while the control group did not receive any intervention. They were assessed at three timepoints (T0: before intervention, T1: immediately after intervention, and T2: 6 weeks after intervention). Repeated measures of analyses of variance (RM-ANOVAs) were used for inter-group comparisons to determine intervention effect from baseline -to T1 and -to T2 for all outcome measures. The individual changes were calculated using the reliable change index (RCI). Key outcomes included depression (BDI-II), anxiety (BAI), epilepsy-related quality of life (QOLIE-31), satisfaction with life (SWLS), and level of mindfulness (MAAS).

    RESULTS: Participants who participated in the MBI showed significant reduction in BDI-II (p = 0.001), significant increases in MAAS (p = 0.027) and QOLIE-31 (p = 0.001) at T1 when compared with the control group. However, BAI and SWLS were not significant. The trend was similar at 6-week follow-up, all outcome measures of MBI remained significant (p

    A randomized controlled study was conducted to evaluate the efficacy of 20-minute mindful breathing in suffering reduction. Forty palliative care patients with an overall suffering score of 4 or above as measured with the Suffering Pictogram were recruited and randomly assigned to 20-minute mindful breathing or 20-minute supportive listening. There was statistically significant reduction of suffering score in both the groups. For Bispectral Index Score value, there was statistically significant difference between intervention and control. A 20-minute mindful breathing could be useful in the alleviation of suffering in palliative care.

    AIM: The purpose of this systematic review is to evaluate the effectiveness of stress management interventional programme in reducing occupational stress among nurses.

    BACKGROUND: Nursing professionals are placed continuously at the forefront in the area of health care which makes them highly exposed to professional stress.

    EVALUATION: Randomized controlled trial studies (RCTs) were systematically searched in eight different databases for works published in English from 2011 to 2019; inclusion criteria were applied by two reviewers critically and assessed the risk of bias using Consolidated Standards of Reporting Trials (CONSORT).

    KEY ISSUES: The systematic search contributed to the extraction of approximately 10 most relevant RCTs. Most of the RCTs considered in this systematic review revealed that the stress reduction interventions and strategies were effective in reducing the levels of occupational stress experienced by nurses.

    CONCLUSIONS: Current review shows that stress management interventional programme tends to be effective, but additional well-designed RCTs are needed to confirm their effectiveness.

    IMPLICATIONS FOR NURSING MANAGEMENT: Implementing stress management interventions within health care organisations are likely to assist nurses in reducing occupational stress and in improving coping strategies used by nurses for dealing with stress.

    AIMS AND OBJECTIVES: To explore the studies that used interventions based on the Mindfulness-Based Stress Reduction (MBSR) for decreasing psychological distress among nurses.

    BACKGROUND: Because of the demanding nature of their work, nurses often have significantly high levels of stress, anxiety and depression. MBSR has been reported to be an effective intervention to decrease psychological distress.

    DESIGN: Systematic review.

    METHODS: The databases included were Science Direct, PubMed, EBSCO host, Springer Link and Web of Science from 2002 to 2018. Interventional studies published in English that used MBSR among nurses to reduce their psychological distress were retrieved for review. The PRISMA guideline was used in this systematic review. The included studies were assessed for quality using "The Quality Assessment Tool For Quantitative Studies (QATFQS)."

    RESULTS: Nine studies were found to be eligible and included in this review. Many benefits, including reduced stress, anxiety, depression, burnout and better job satisfaction, were reported in these studies.

    CONCLUSION: The adapted/brief versions of MBSR seem promising for reducing psychological distress in nurses. Future research should include randomised controlled trials with a larger sample size and follow-up studies. There should also be a focus on creative and effective ways of delivering MBSR to nurses.

    RELEVANCE TO CLINICAL PRACTICE: The results of this review are substantial for supporting the use of MBSR for nurses' psychological well-being.

    Pursuing undergraduate medical training can be very stressful and academically challenging experience. A 5-week mindfulness-based stress management (MBSM/Mindful-Gym) program was developed to help medical students cope with stress. The aim of this study was to evaluate the effectiveness of the intervention in reducing stress among students in a medical school in Malaysia. Seventy-five medical students participated in the program. They were stratified according to years of studies and randomly allocated to intervention (N = 37) and control groups (N = 38). The following outcome variables were measured at pre- and post-intervention: mindfulness (with Mindful Awareness Attention Scale); perceived stress (with Perceived Stress Scale); mental distress (with General Health Questionnaire), and self-efficacy (with General Self-efficacy Scale). Hierarchical multiple regressions were used to analyse the effect of group (intervention vs. control) on changes in the outcome variables. There were significant improvements at one week post-intervention in all outcome variables: mindfulness (β = 0.19, ΔR2 = 0.04, p = .040, f (2) = 0.05), perceived stress (β = -0.26, ΔR2 = 0.07, p = .009, f (2) = 0.10); mental distress (β = -0.28, ΔR2 = 0.10, p = .003, f (2) = 0.15); and self-efficacy (β = 0.30, ΔR2 = 0.09, p < .001, f (2) = 0.21). Six months after the intervention, those who had joined the program reported higher self-efficacy compared to those in the control group (β = 0.24, ΔR2 = 0.06, p = .020, f (2) = 0.08); but there was no difference in other outcome measures. More than 90% of the participants found the program applicable in helping patients and all reported that they would recommend it to others. This study indicates that the program is potentially an effective stress management program for medical students in Malaysia.

    A pilot study was conducted to evaluate the efficacy of 5-minute mindful breathing in distress reduction. Twenty palliative care patients and family caregivers with a distress score ≥4 measured by the Distress Thermometer were recruited and randomly assigned to mindful breathing or "listening" (being listened to). Median distress reductions after 5 minutes were 2.5 for the mindful breathing group and 1.0 for the listening group. A significantly larger reduction in the distress score was observed in the mindful breathing group (Mann-Whitney U test: U = 8.0, n1 = n2 = 10, mean rank1 = 6.30, mean rank2 = 14.70, z = -3.208, P = .001). The 5-minute mindful breathing could be useful in distress reduction in palliative care.

    This study was conducted to identify the prevalence of stress, types of stressors, consequences of stress and stress relievers among undergraduate dental students at the University of Malaya during the different years of study. A descriptive cross-sectional quantitative study was conducted using a self-administered questionnaire among Bachelor of Dental Surgery students during Years 2 to 5. A 100% response rate was obtained. The instrument asked questions about the preceding academic year. The results of the questionnaire reveal the prevalence of stress was 100%. The most common cause of stress among preclinical students was academic concerns and among clinical students was patient management and clinical performance. Physical and behavioral problems were reported as consequences of stress. Most students overcame stress by having strong interpersonal relationships.

    The present article begins with an overview of how staff at the Center for Dialogue and Human Wellbeing (CDBH)-at Tecnológico de Monterrey University in Chihuahua, México-approach the process of conflict transformation. Specifically, it focuses on CDBH's strategies for dealing with historical injury, as well as the individual and collective trauma existing between and among communities engaged in ongoing conflict. It proceeds to examine how traumatic memories are stored in the mind/brain, and how trauma can impact on individuals and communities locked into a cycle of violence. The ensuing section provides an overview of the debate and the literature concerning psychotherapeutic and holistic-kinesthetic approaches for addressing individual and collective trauma. A hypothetical workshop is then offered to give readers a clear idea of how trauma work is actually carried out. The article ends by asking what approaches can best be applied for transforming collective trauma into sacred memories, which can become the driving force for a continuing commitment to building and sustaining peace among segments of communities that had previously been in conflict with one another.

    Alternate nostril breathing (ANB) is one of the best and easiest breathing exercises. ANB exercise has beneficial effects on cardiac function in healthy and diseased people. The objectives of this study were to assess the effects of ANB exercise on cardiac physiology among healthy medical students. This was a prospective interventional study that was conducted in the Department of Physiology, Chittagong Medical College (CMC), Chattogram, Bangladesh, from July 2017 to June 2018. A total of 100 research participants (RPs) aged 18-20 years, Year-I medical students of CMC, were selected. A simple random sampling method was adopted. The selection was done after the inclusion and exclusion criteria were applied. The age and body mass index (BMI) of the RPs were analogous in both the control and experimental groups. Cardiac parameters, like pulse and blood pressure (BP), were measured. The initial baseline data were recorded for both groups and after 4 weeks. The research respondents of the experimental group performed ANB exercise for 4 weeks. The mean value pulse and BP were significantly (p < 0.001) changed after breathing exercise, compared to the values before the breathing exercise. The results of this study suggest that cardiac function significantly improves after the breathing exercise. Therefore, ANB can be recommended for increasing cardiac efficiency.

    Alternate nostril breathing (ANB) is one of the best and easiest breathing exercises (pranayama) of yoga that are good for health and physical fitness. ANB exercise has beneficial and therapeutic effects on respiratory function in both normal as well as diseased humans. This study was conducted with the objective of assessing the physiological effects of short-term ANB exercise on respiratory function in healthy adult individuals leading a stressful life. This prospective interventional study was conducted in the Department of Physiology, Chittagong Medical College (CMC), Chattogram, Bangladesh from July 2017 to June 2018. A total of 100 participants aged 18-20 years, studying in the first year in CMC, were included by using a simple random sampling method. Among them, 50 participants were enrolled in the experimental group. Age- and BMI-matched 50 participants constituted the control group. Height, weight were measured, and BMI was calculated. The participants of the experimental group performed ANB exercise over 4 weeks for 10 min/day. The control participants were neither trained nor allowed to practice nostril breathing during the whole study period. Respiratory parameters like forced vital capacity (FVC), forced expiratory volume in 1st second (FEV1), and peak expiratory flow rate (PEFR) were measured by using a digital spirometer (Chest graph HI-101, Japan). Readings were taken in a healthy upright sitting posture in the control and experimental group initially and after 4 weeks. Student's t-test was conducted by using SPSS for windows version-23. The mean value of FVC, FEV1, PEFR were significantly (P < 0.001) changed after the ANB exercise when compared to the values before breathing exercise. The results of this study suggest that respiratory function is significantly improved after the ANB exercise. Therefore, ANB can be recommended for increasing respiratory efficiency.

    Objective Psychotherapy is a common non-pharmacological approach to help cancer patients in their psychological distress. The benefit of psychotherapies was documented, but the types of psychotherapies proposed are varied. Given that the previous literature review was a decade ago and no quantitative analysis was done on this topic, we again critically and systematically reviewed all published trials on psychotherapy in cancer patients. Method We identified 17 clinical trials on six types of psychotherapy for cancer patients by searching PubMed and EMBASE. Result There were four trials involved adjunct psychological therapy which were included in quantitative analysis. Each trial demonstrated that psychotherapy improved the quality of life and coping in cancer patients. There was also a reduction in distress, anxiety, and depression after a psychological intervention. However, the number and quality of clinical trials for each type of psychotherapy were poor. The meta-analysis of the four trials involved adjunct psychological therapy showed no significant change in depression, with only significant short-term improvement in anxiety but not up to a year-the standardized mean differences were -0.37 (95% confidence interval (CI) = -0.57, -0.16) at 2 months, -0.21 (95% CI = -0.42, -0.01) at 4 months, and 0.03 (95 % CI = -0.19, 0.24) at 12 months. Conclusion The evidence on the efficacy of psychotherapy in cancer patients is unsatisfactory. There is a need for more rigorous and well-designed clinical trials on this topic.

    Patients with end stage renal disease on hemodialysis are affected by physiological and psychological stressors, which contribute to poor quality of life and negative clinical outcomes. Depression, anxiety, and stress are highly prevalent in this population. Effective interventional strategies are required to manage these psychological symptoms. Acupressure has been believed to be one of the complementary therapies that could promote psychological wellbeing.

    BACKGROUND: Many adults with type 2 diabetes mellitus (T2DM) experience a psychosocial burden and mental health problems associated with the disease. Diabetes-related distress (DRD) has distinct effects on self-care behaviours and disease control. Improving DRD in adults with T2DM could enhance psychological well-being, health-related quality of life, self-care abilities and disease control, also reducing depressive symptoms.

    OBJECTIVES: To assess the effects of psychological interventions for diabetes-related distress in adults with T2DM.

    SEARCH METHODS: We searched the Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, BASE, WHO ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was December 2014 for BASE and 21 September 2016 for all other databases.

    SELECTION CRITERIA: We included randomised controlled trials (RCTs) on the effects of psychological interventions for DRD in adults (18 years and older) with T2DM. We included trials if they compared different psychological interventions or compared a psychological intervention with usual care. Primary outcomes were DRD, health-related quality of life (HRQoL) and adverse events. Secondary outcomes were self-efficacy, glycosylated haemoglobin A1c (HbA1c), blood pressure, diabetes-related complications, all-cause mortality and socioeconomic effects.

    DATA COLLECTION AND ANALYSIS: Two review authors independently identified publications for inclusion and extracted data. We classified interventions according to their focus on emotion, cognition or emotion-cognition. We performed random-effects meta-analyses to compute overall estimates.

    MAIN RESULTS: We identified 30 RCTs with 9177 participants. Sixteen trials were parallel two-arm RCTs, and seven were three-arm parallel trials. There were also seven cluster-randomised trials: two had four arms, and the remaining five had two arms. The median duration of the intervention was six months (range 1 week to 24 months), and the median follow-up period was 12 months (range 0 to 12 months). The trials included a wide spectrum of interventions and were both individual- and group-based.A meta-analysis of all psychological interventions combined versus usual care showed no firm effect on DRD (standardised mean difference (SMD) -0.07; 95% CI -0.16 to 0.03; P = 0.17; 3315 participants; 12 trials; low-quality evidence), HRQoL (SMD 0.01; 95% CI -0.09 to 0.11; P = 0.87; 1932 participants; 5 trials; low-quality evidence), all-cause mortality (11 per 1000 versus 11 per 1000; risk ratio (RR) 1.01; 95% CI 0.17 to 6.03; P = 0.99; 1376 participants; 3 trials; low-quality evidence) or adverse events (17 per 1000 versus 41 per 1000; RR 2.40; 95% CI 0.78 to 7.39; P = 0.13; 438 participants; 3 trials; low-quality evidence). We saw small beneficial effects on self-efficacy and HbA1c at medium-term follow-up (6 to 12 months): on self-efficacy the SMD was 0.15 (95% CI 0.00 to 0.30; P = 0.05; 2675 participants; 6 trials; low-quality evidence) in favour of psychological interventions; on HbA1c there was a mean difference (MD) of -0.14% (95% CI -0.27 to 0.00; P = 0.05; 3165 participants; 11 trials; low-quality evidence) in favour of psychological interventions. Our included trials did not report diabetes-related complications or socioeconomic effects.Many trials were small and were at high risk of bias for incomplete outcome data as well as possible performance and detection biases in the subjective questionnaire-based outcomes assessment, and some appeared to be at risk of selective reporting. There are four trials awaiting further classification. These are parallel RCTs with cognition-focused and emotion-cognition focused interventions. There are another 18 ongoing trials, likely focusing on emotion-cognition or cognition, assessing interventions such as diabetes self-management support, telephone-based cognitive behavioural therapy, stress management and a web application for problem solving in diabetes management. Most of these trials have a community setting and are based in the USA.

    AUTHORS' CONCLUSIONS: Low-quality evidence showed that none of the psychological interventions would improve DRD more than usual care. Low-quality evidence is available for improved self-efficacy and HbA1c after psychological interventions. This means that we are uncertain about the effects of psychological interventions on these outcomes. However, psychological interventions probably have no substantial adverse events compared to usual care. More high-quality research with emotion-focused programmes, in non-US and non-European settings and in low- and middle-income countries, is needed.

    Generally speaking, institutionalised children and adolescents are at greatly increased risk of serious mental and behavioural problems, up to seven times more than their peers. Life skills- based interventions using peer enforcement have been introduced as effective program to improve adolescents' emotional and behavioral health. Therefore, the current randomized control study aimed to determine, if a life skills-based intervention could improve the emotional health and self-esteem among Malaysian adolescents in orphanages. Overall, 271 male and female adolescents (13-18 years old) from 8 orphanages in Klang valley, Malaysia participated in the study. Comparing the intervention to control group within 3 points of time, the finding of the study showed that immediately after finishing the interventional sessions (post-test), the mean scores of depression (F = 33.80, P<0.001, η2 = 0.11), anxiety (F = 6.28, P = 0.01, η2 = 0.02), stress (F = 32.05, P<0.001, η2 = 0.11) and self-esteem (F = 54.68, P<0.001, η2 = 0.17) were significantly decreased compared to the pre-test values. However, there was no significant difference between two groups in the depression mean scores (F = 2.33, P = 0.13). Regarding to the interaction between group and test a significant change was seen in the mean score of all 4 variables including depression (F = 31.04, P<0.001, η2 = 0.10), anxiety (F = 14.21, P<0.001, η2 = 0.05), stress (F = 15.67, P<0.001, η2 = 0.06) and self-esteem (F = 13.29, P<0.001, η2 = 0.05). Furthermore, except depression (Δmean = -1.37, P<0.001), no significant difference was seen between study variables' mean scores between post- and follow-up test (p>0.001). These results provide preliminary approve for LSE to enhance emotional health and self-esteem in orphanages.

    BACKGROUND: Depression is associated with lowered mood, anxiety, anhedonia, cognitive impairments, and even suicidal tendencies in severe cases. Yet few studies have directed acupuncture's mechanism toward enhancing axonal repair correlated with synaptic plasticity and anti-inflammatory effects related to oxidative stress in the hippocampus.

    METHODS: Male Sprague-Dawley (SD) rats were randomly divided into control group (CON), chronic unpredictable mild stress (CUMS) group, CUMS + electroacupuncture group (EA), and CUMS + fluoxetine group (FLX) (n = 10/group). Rats were given a 28-day treatment at the Shangxing (GV23) and Fengfu (GV16) acupoints with electroacupuncture or fluoxetine (2.1 mg/kg).

    RESULTS: Rats exposed to CUMS induced depression-like behaviors and spatial learning-memory impairment, changed the ionized calcium binding adaptor molecule 1 (IBA-1), Vglut1, myelin basic protein (MBP), and postsynaptic density protein 95 (PSD95) level of hippocampal, increased the Nod-like receptor protein 3 (NLRP3), atypical squamous cell (ASC), Caspase level and hippocampal reactive oxygen species (ROS), and prompted the activation of Epha4-mediated signaling and an inflammatory response. Conversely, electroacupuncture administration reduced these changes and prevented depression-like behaviors and cognitive impairment. Electroacupuncture also promoted hippocampal expression of Sirtuin1(SIRT1), Nuclear factor erythroid 2-like (Nrf2), Heme oxygenase-1 (HO-1); reduced the expression of interleukin-1β (IL-1β), interleukin-18 (IL-18), and tumor necrosis factor-alpha (TNF-α); and prevented neural damage, particularly the synaptic myelin sheath, and neuroinflammation by regulating Eph receptor A4 (EphA4) in the hippocampal.

    CONCLUSION: These results indicate that electroacupuncture prevents depression-like behaviors with cognitive impairment and synaptic and neuronal damage, probably by reducing EphA4, which mediates ROS hyperfunction and the inflammatory response.
