Abstract
Chronic pain affects mental and physical health and alters brain structure and function. Interventions that reduce chronic pain are also associated with changes in the brain. A number of non-invasive strategies can promote improved learning and memory and increase neuroplasticity in older adults. Intermittent fasting and glucose administration represent two such strategies with the potential to optimize the neurobiological environment to increase responsiveness to recognized pain treatments. The purpose of the pilot study was to test the feasibility and acceptability of intermittent fasting and glucose administration paired with a recognized pain treatment activity, relaxation and guided imagery. A total of 32 adults (44% W, 56% M), 50 to 85 years of age, with chronic knee pain for three months or greater participated in the study. Four sessions were completed over an approximate two-week period. Findings indicate the ability to recruit, randomize, and retain participants in the protocol. The procedures and measures were reasonable and completed without incident. Participant adherence was high and exit interview feedback positive. In summary, the pilot study was feasible and acceptable, providing the evidence necessary to move forward with a larger clinical trial.

Breastfeeding medicine : the official journal of the Academy of Breastfeeding Medicine. 2019;(1):33-38
Abstract
OBJECTIVE To compare the effects of different relaxation techniques on physiological outcomes and perceived relaxation in primiparous Chinese mothers breastfeeding their healthy term infant. DESIGN Twenty primiparous mothers who were breastfeeding were enrolled into a within-subject study, and attended six treatment sessions in randomized order (relaxation meditation tape [RM], music tape [M], relaxation lighting [L], combined RM+L, and combined M+L, and control session with no intervention), with a washout period of 1-3 days between sessions. Heart rate, systolic and diastolic blood pressure (SBP, DBP), fingertip temperature, and perceived relaxation were assessed before and after each session. RESULTS Compared with the pretest state, significant changes for all outcomes (p < 0.05) were observed for RM, RM+RL, M+RL treatments, whereas differences for all outcomes apart from SBP were observed for treatment M. Compared with the control, significant changes were found in all outcomes for RM treatment, and in fingertip temperature and perceived relaxation for all treatments. CONCLUSION Our findings suggest that simple relaxation techniques can reduce both perceived and physiological markers of stress in breastfeeding mothers. Overall, the RM was the most effective technique compared with the control state, considering the number of outcomes affected, effect sizes, and simplicity, suggesting this merits further research in this population.

Abstract
BACKGROUND Biological signaling and communication between mothers and infants during breastfeeding may shape infant behavior and feeding. This signaling is complex and little explored in humans, although it is potentially relevant for initiatives to improve breastfeeding rates. OBJECTIVES The aim of this study was to investigate physiological and psychological aspects of mother-infant signaling during breastfeeding experimentally, testing the effects of a relaxation intervention on maternal psychological state, breast milk intake, milk cortisol levels, and infant behavior and growth. METHODS Primiparous breastfeeding mothers and full-term infants were randomly assigned to receive relaxation therapy [intervention relaxation group; n = 33 (RG)] or to the control group [n = 31 (CG); no relaxation therapy] at 2 wk postpartum. Both groups received standard breastfeeding support. Home visits were conducted at 2 (HV1), 6 (HV2), 12 (HV3) and 14 (HV4) wk to measure maternal stress and anxiety, breast milk intake and milk cortisol, and infant behavior and growth. RESULTS RG mothers had lower stress scores postintervention than the CG (HV3 ∆ = -3.13; 95% CI: -5.9, -0.3) and lower hindmilk cortisol at HV1 (∆ = -44.5%; 95% CI: -76.1%, -12.9%) but not at HV2. RG infants had longer sleep duration (∆ = 82 min/d; 95% CI: 16, 149 min/d) at HV2 and higher gains in weight and body mass index standardized deviation score than the CG infants (∆ = 0.76; 95% CI: 0.3, 1.22; and ∆ = 0.59; 95% CI: 0.09, 1.1, respectively). RG infants had a mean milk intake at HV3 that was 227 g/d higher than that of the CG infants (P = 0.031) after controlling for gender and milk intake at HV1. CONCLUSIONS The trial shows the effectiveness of a simple relaxation intervention for improving maternal and infant outcomes and identifies some potential signaling mechanisms for investigation in future and larger studies, especially in settings where mothers are more stressed, such as those with preterm or low birth weight infants. This trial was registered at clinicaltrials.gov as NCT01971216.

Supportive interventions to improve physiological and psychological health outcomes among patients undergoing cystectomy: a systematic review.
Quirk, H, Rosario, DJ, Bourke, L
BMC urology. 2018;(1):71
Abstract
BACKGROUND Our understanding of effective perioperative supportive interventions for patients undergoing cystectomy procedures and how these may affect short and long-term health outcomes is limited. METHODS Randomised controlled trials involving any non-surgical, perioperative interventions designed to support or improve the patient experience for patients undergoing cystectomy procedures were reviewed. Comparison groups included those exposed to usual clinical care or standard procedure. Studies were excluded if they involved surgical procedure only, involved bowel preparation only or involved an alternative therapy such as aromatherapy. Any short and long-term outcomes reflecting the patient experience or related urological health outcomes were considered. RESULTS Nineteen articles (representing 15 individual studies) were included for review. Heterogeneity in interventions and outcomes across studies meant meta-analyses were not possible. Participants were all patients with bladder cancer and interventions were delivered over different stages of the perioperative period. The overall quality of evidence and reporting was low and outcomes were predominantly measured in the short-term. However, the findings show potential for exercise therapy, pharmaceuticals, ERAS protocols, psychological/educational programmes, chewing gum and nutrition to benefit a broad range of physiological and psychological health outcomes. CONCLUSIONS Supportive interventions to date have taken many different forms with a range of potentially meaningful physiological and psychological health outcomes for cystectomy patients. Questions remain as to what magnitude of short-term health improvements would lead to clinically relevant changes in the overall patient experience of surgery and long-term recovery.

Abstract
BACKGROUND Listening to natural sounds is applied in health contexts in order to induce relaxation. However, it remains unclear whether this effect is equally efficacious in all individuals or whether it depends on interindividual differences. Given that individuals differ in how they are impaired by somatic complaints, we investigated whether somatic complaints moderate the stress-reducing effect of listening to water sounds. METHODS Sixty healthy women (Mage = 25 years) were randomly allocated to 3 different conditions (listening to water sounds, a relaxing piece of music, or no auditory stimulus: n = 20 per condition) for 10 minutes before they were exposed to a standardized psychosocial stress task. Salivary cortisol was assessed before, during, and after the stress task. For binary logistic regression analyses, participants were divided into 2 groups: 1 group with a high salivary cortisol release and 1 group with low cortisol release. The Freiburg Complaints Inventory was used to assess occurrence of somatic complaints. RESULTS A significant moderating effect of somatic complaints on cortisol secretion was found in the group listening to water sounds (χ(1) = 5.87, P < .015) but not in the other 2 groups, explaining 35.7% of the variance and correctly classifying 78.9% of the cases. CONCLUSION The stress-reducing effect of listening to water sounds appears to depend on the occurrence of somatic complaints. This effect was not found in the music or silence condition. Individuals with somatic complaints may benefit from other, potentially more powerful forms of stress-reducing interventions, that is, combinations of visual and auditory stimuli. TRIAL REGISTRATION not applicable (pilot study).

Abstract
BACKGROUND In Western societies, cardiovascular (CV) disease is the primary cause of mortality, and high blood pressure (BP) is the main reversible factor leading to CV disease. Dietary habits and psychosocial stress contribute to the establishment of hypertension, while its role in the control of high BP is currently examined. In this study, we examined the effect and feasibility of a combined intervention of dietary education and stress management on the control of hypertension. METHODOLOGY A randomized, controlled pilot study was designed to evaluate the effect of combined education on stress management techniques and dietary habits (Mediterranean diet principle) on office BP after eight weeks. RESULTS Of the 45 randomized subjects, 36 were included in the final analysis (control group = 20 (age: 67 ± 12 years, 31.8%, males) and intervention group = 16 (age: 62 ± 12 years, 47%, males)). CV disease risk factors (except smoking), BP, dietary habits, perceived stress and physical activity (all assessed with validated questionnaires) were similar between the two groups at baseline. After eight weeks, office BP (systolic and diastolic) and perceived stress were significantly reduced, whereas the adherence in Mediterranean diet principle was significantly increased, but only in the intervention group. CONCLUSIONS A combined intervention of stress management techniques and Mediterranean diet education seems to be beneficial for BP reduction. Such interventions could possibly serve as a complementary treatment along with drug therapy or in the early treatment of high normal BP. A call to action for designing epidemiological studies and evaluating the efficacy of such non-pharmacological treatment strategies is therefore warranted.

Schmid, G, Henningsen, P, Dieterich, M, Sattel, H, Lahmann, C
Journal of neurology, neurosurgery, and psychiatry. 2011;(6):601-6
Abstract
BACKGROUND About 30-50% of complex dizziness disorders are organically not sufficiently explained or related to a psychiatric disorder. Of patients with such dizziness disorders, 80% are severely impaired by dizziness in their daily and working lives; nevertheless, they are often not diagnosed or treated adequately. OBJECTIVES This review aims to give a systematic overview of psychotherapeutic approaches and their efficacy regarding the treatment of dizziness that is medically not sufficiently explained or related to a psychiatric disorder. METHODS A systematic literature search was conducted in Medline, PSYNDEX and PsycINFO. Included in this systematic review were (randomised) controlled trials ((R)CTs) concerning psychotherapy in patients with dizziness, medically not sufficiently explained or associated with a psychiatric disorder. If possible, Hedges' g was used to express the effect sizes (ES) of the treatment. Heterogeneity was assessed using the Q statistic. In addition, the quality of the studies was rated. RESULTS Three (R)CTs were included. All studies used cognitive-behavioural treatment methods in combination with relaxation techniques or vestibular rehabilitation. All studies suggested that psychotherapy may provide improvement. The mean ES in the treatment groups was 0.46 (95% CI 0.05 to 0.88) for dizziness related outcome, 0.10 (-0.44 to 0.64) for anxiety and 0.17 (-0.24 to 0.58) for depression whereas in the control groups the mean dizziness related ES was -0.04 (-0.44 to 0.37), anxiety related ES was -0.03 (-0.43 to 0.38) and depression related ES was -0.02 (-0.42 to 0.38). The quality of the studies was average. Sample sizes were small, however, and there was a lack of long term studies. CONCLUSION This systematic review provides some preliminary evidence that psychotherapy may be effective in patients with dizziness that is medically not sufficiently explained or due to a psychiatric disorder. The results should be replicated in larger samples and follow-up RCTs.

Neves, A, Alves, AJ, Ribeiro, F, Gomes, JL, Oliveira, J
Journal of cardiopulmonary rehabilitation and prevention. 2009;(5):304-9
Abstract
PURPOSE To examine the effect of a cardiac rehabilitation program with relaxation therapy (CPRT) in comparison with cardiac rehabilitation alone on psychological stress, hemodynamic variables, cardiac risk factors, and cardiac-related hospital admissions in patients with coronary artery disease. METHODS Patients (N = 81) were randomly assigned to either a 12-week cardiac rehabilitation program alone (CPA) or a CPRT. Perceived stress, blood pressure, heart rate, rate-pressure product value, total cholesterol level, body mass index, smoking status, and physical activity were recorded at baseline and following the 12-week intervention. Cardiac-related hospital admissions were analyzed in a 2-year follow-up. RESULTS Perceived stress declined in both groups, although this improvement was significantly superior in the CPRT (31.5 +/- 4.9 vs 23.4 +/- 4.1; P CONCLUSIONS Relaxation therapy was associated with a positive effect on psychological stress and hemodynamic variables beyond that promoted by cardiac rehabilitation alone.

Janbozorgi, M, Zahirodin, A, Norri, N, Ghafarsamar, R, Shams, J
Eastern Mediterranean health journal = La revue de sante de la Mediterranee orientale = al-Majallah al-sihhiyah li-sharq al-mutawassit. 2009;(3):629-38
Abstract
To determine the effects of integrative relaxation training (IRT) on emotional stability, we exposed 32 patients diagnosed with anxiety disorder to a pre-test (16PF) and to 12 sessions of group psychoeducation training. Patients were randomly assigned to 2 groups (study 17 and control 15 patients). The study group received 12 weekly group sessions of IRT. Level of anxiety was evaluated in a post-test using a questionnaire and the State-Trait Anxiety Inventory (STAI). Emotional stability and level of anxiety were significantly reduced in the study group: there was a marked increase in scores for emotionally s and venturesome and a decrease in scores for apprehensive and tense. The STAI score was statistically significantly lower in the study group.

Hoyer, J, Beesdo, K, Gloster, AT, Runge, J, Höfler, M, Becker, ES
Psychotherapy and psychosomatics. 2009;(2):106-15
Abstract
BACKGROUND Worry exposure (WE) is a core element of cognitive-behavioral treatment for generalized anxiety disorder (GAD). Its efficacy as a stand-alone treatment method (without further cognitive-behavioral therapy interventions) has never been tested.We aimed to examine whether WE alone is as efficacious as the empirically supported stand-alone treatment for GAD, applied relaxation (AR). METHODS In a randomized controlled study, 73 outpatients meeting DSM-IV criteria for GAD as primary diagnosis were allocated to either WE or AR or a waiting list control group; in a 2nd randomization procedure the waiting list subjects were reallocated to WE or AR. The treatment was manualized (15 sessions with WE or AR), included 6-month and 1-year follow-ups, as well as last observation carried forward and completer analyses, and was controlled for allegiance effects.The Hamilton Anxiety Rating Scale and the State-Trait Anxiety Scale were used as primary outcome measures. Self-report scales of anxiety, worrying and depression including negative metacognition about worrying and thought suppression served as secondary outcome measures. RESULTS The dropout rate was moderate. The pre-/posttreatment effects were high for the Hamilton Anxiety Rating Scale (standardized mean difference >1) and for the State-Trait Anxiety Inventory (standardized mean difference >0.87). The proportion of patients reaching high end state functioning was 48% (WE) and 56% (AR). WE and AR did not differ with regard to dropout rate or treatment effects. The treatment effects were stable at 6 month and 1 year follow-up. CONCLUSION This is the first study to show that a stand-alone exposure in sensu technique--WE--is efficacious in the treatment of GAD. Both AR and WE seem to represent effective principles of change in GAD.
