A brief relaxation intervention reduces stress and improves surgical wound healing response: a randomised trial

The EUropean PErioperative MEdical Networking (EUPEMEN) project and recommendations for perioperative care in colorectal surgery: a quality improvement study

BACKGROUND

Despite consensus supporting enhanced recovery programs, their full implementation in such a context is difficult due to conventional practices within various groups of professionals. The goal of the EUropean PErioperative MEdical Networking (EUPEMEN) project was to bring together the expertise and experience of national clinical professionals who have previously helped deliver major change programs in their countries and to use them to spread enhanced recovery after surgery protocols (ERAS) in Europe. The specific aim of this study is to present and discuss the key points of the proposed recommendations for colorectal surgery.

MATERIALS AND METHODS

Five partners from university hospitals in four European countries developed the project as partners. Following a non-systematic review of the literature, the European consensus panel generated a list of recommendations for perioperative care in colorectal surgery. A list of recommendations was formulated and distributed to collaborators at each center to allow modifications or additional statements. These recommendations were then discussed in three consecutive meetings to share uniform ERAS protocols to be disseminated.

RESULT

The working group developed (1) the EUPEMEN online platform to offer, free of charge, evidence-based standardized perioperative care protocols, learning activities, and assistance to health professionals interested in enhancing the recovery of their patients; (2) the preparation of the EUPEMEN Multimodal Rehabilitation manuals; (3) the training of the trainers to teach future teachers; and (4) the dissemination of the results in five multiplier events, one for each partner, to promote and disseminate the protocols.

CONCLUSION

The EUPEMEN project allowed the sharing of the expertise of many professionals from four different European countries with the objective of training the new generations in the dissemination of ERAS protocols in daily clinical practice through a new learning system. This project was proposed as an additional training tool for all the enhanced recovery program teams.

Relaxation intervention to improve diabetic foot ulcer healing: protocol for a pilot study with a nested qualitative study

OBJECTIVE

A mixed-methods approach nested in a pilot three-arm randomised controlled trial (RCT) was conducted to evaluate the feasibility and acceptability of an intervention of progressive muscle relaxation with guided imagery (experimental group) compared to a neutral guided imagery placebo (active control group) and a group that did not receive any psychological intervention (passive control group). The purpose was to inform a future definitive RCT that will test its effectiveness. Qualitatively, this study examined patients and health professionals' perspectives regarding the relaxation intervention, in order to assess the acceptability and applicability of relaxation as an adjuvant therapy.

METHOD

Participants must have had a diagnosis of diabetes and diabetic foot disease; one or two active hard-to-heal ulcers at the time of the assessment; and clinical levels of stress or anxiety or depression. Participants were randomised and assessed at three timepoints after the first hospital consultation for hard-to-heal diabetic foot ulcer (DFU).

RESULTS

Rates of eligibility, recruitment, refusal, adherence to study protocol, participation in follow-up and dropout, and patients' satisfaction with the relaxation intervention were assessed as primary outcomes. Secondary outcomes were DFU healing; patients' DFU-related quality of life; physical and mental quality of life; perceived stress; emotional distress; adherence to DFU care; perceptions of DFU; as well as arterial systolic/diastolic pressure and heart rate.

CONCLUSION

The results of this pilot study contributed to clarification and better elucidation of the benefits of relaxation techniques regarding patients' HRQoL and DFU healing.

A Look Forward and a Look Back: The Growing Role of ERAS Protocols in Orthopedic Surgery

The success of enhanced recovery after surgery (ERAS) protocols in improving patient outcomes and reducing costs in general surgery are widely recognized. ERAS guidelines have now been developed in orthopedics with the following recommendations. Preoperatively, patients should be medically optimized with a focus on smoking cessation, education, and anxiety reduction. Intraoperatively, using multimodal and regional therapies like neuraxial anesthesia and peripheral nerve blocks facilitates same-day discharge. Postoperatively, early nutrition with appropriate thromboprophylaxis and early mobilization are essential. As the evidence of their improvement in patient outcomes and satisfaction continues, these pathways will prove invaluable in optimizing patient care in orthopedics.

Acupressure can reduce preoperative anxiety in adults with elective surgery: A systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Preoperative anxiety is prevalent amongst adults with elective surgery and is associated with multiple detrimental perioperative physiological effects. Increasing studies support the effectiveness of acupressure in managing preoperative anxiety. However, the magnitude of acupressure's positive association with preoperative anxiety is still unclear due to a lack of rigorous evidence synthesis.

OBJECTIVE

To estimate the efficacy of acupressure on preoperative anxiety and physiological parameters amongst adults scheduled for elective surgery.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Search terms were combined for acupressure and preoperative anxiety in PubMed, Cochrane Library, EMBASE, CINAHL, China National Knowledge Infrastructure, and WanFang Data Knowledge Service Platform to search for eligible randomised controlled trials from the inception of each database through September 2022.

METHODS

Pairs of researchers independently screened and extracted data from included studies. The risk of bias was assessed using the Cochrane risk of bias tool Version 2.0. Meanwhile, random-effects meta-analysis of overall effects and prespecified subgroup (i.e., surgery types, intervention providers, and acupressure stimulation tools) was conducted using Review Manager Software 5.4.1. Meta-regression was performed to explore study-level variables that may contribute to heterogeneity using STATA 16.

RESULTS

Of 24 eligible randomised controlled trials, there were a total of 2537 participants from 5 countries contributed to this synthesis. When comparing acupressure with usual care or placebo, acupressure showed a large effect size for preoperative anxiety (SMD = -1.30; 95%CI = -1.54 to -1.06; p < 0.001; I2 = 86%). The significant mean reduction of heart rate, and systolic and diastolic blood pressure was -4.58 BPM (95%CI = -6.70 to -2.46; I2 = 89%), -6.05 mmHg (95%CI = -8.73 to -3.37; p < 0.001; I2 = 88%), and -3.18 mmHg (95%CI = -5.09 to -1.27; p = 0.001; I2 = 78%), respectively. Exploratory subgroup analyses showed significant differences in surgery types and acupressure stimulation tools, whilst the intervention providers (i.e., healthcare professionals and self-administered) showed no statistically significant difference for acupressure therapy. None of the predefined participants and study-level characteristics moderated preoperative anxiety through meta-regression.

CONCLUSION

Acupressure appears efficacious as a therapy for improving preoperative anxiety and physiological parameters amongst adults with elective surgery. Self-administered acupressure, which is effective with a large effect, may be considered as an evidence-based approach to managing preoperative anxiety. Hence, this review aids in the development of acupressure in different types of elective surgeries and the improvement of the rigour of acupressure therapy.

Relaxation intervention to improve diabetic foot ulcer healing: Results from a pilot randomized controlled study

This pilot randomised controlled study (RCT) aimed to assess the feasibility and acceptability of a progressive muscle relaxation with guided imagery intervention (experimental group [EG]) compared to a neutral guided imagery placebo (active control group [ACG]) and standard care to diabetic foot ulcer [DFU] treatment (passive control group [PCG]), to decide on the need for a definitive RCT. Diabetic foot patients with one or two chronic DFU and significant levels of stress/anxiety/depression were recruited and assessed during a period of 6 months, at three moments. Primary outcomes: feasibility rates and satisfaction with relaxation sessions. Secondary outcomes: DFU healing score, DFU-related quality of life (DFUQoL), physical and mental HRQoL, stress and emotional distress, DFU representations, arterial blood pressure, and heart rate. A total of 146 patients completed the baseline (T0) assessment with 54 participants presenting significant distress being randomised into three groups. Patients were assessed 2 months post-intervention (T1) and 4 months after T1 (T2). Feasibility rates showed reduced values on eligibility, recruitment and inclusion in the study, although with an acceptable rate of refusal lower than 10%. On average, participants reported being satisfied with relaxation sessions and recommended them to other patients. Differences between groups showed that, at T1, PCG participants reported higher levels of stress than those from EG and ACG. Within-group differences showed improvements in stress, distress, DFUQoL and DFU extent over time only in EG and ACG. Only EG showed significant changes in DFU representations at T1. The results suggest that relaxation may be a promising coping strategy to deal with DFU distress and an important adjuvant therapy for DFU healing, supporting the implementation of a definitive RCT.

Relax to Heal? Perspectives of Patients with Diabetic Foot Ulcers and Health Professionals on Relaxation Sessions for Wound Healing

OBJECTIVE

To explore patients' and healthcare professionals' (HPs') perspectives on the suitability/acceptability of a relaxation intervention, its effects on patients' well-being and diabetic foot ulcer (DFU) healing, and its incorporation into the multidisciplinary management of patients with diabetic foot.

METHODS

This qualitative study was nested within a three-arm pilot randomized controlled trial. Patients with a chronic DFU received four relaxation sessions. Investigators then interviewed patients, physicians, and nurses involved with diabetic foot consultations. Interviews were audio-recorded, transcribed, and analyzed using thematic content analysis.

RESULTS

Five themes emerged from patient's interviews about the suitability/acceptability of the relaxation intervention: perceptions regarding the psychological intervention, distress, the relaxation technique, changes in the patient's life, and changes in DFU/contribution to healing. Three themes emerged from interviews with HPs: perceptions regarding relaxation, changes in the patient, and changes in DFU/healing. Regarding the feasibility of the relaxation intervention, three themes emerged for both patients and HPs: suggested modifications, stressors/difficulties, and impact of COVID-19 pandemic. The utility theme emerged only in HP interviews, with subthemes of patients' distress, psychological interventions, relaxation intervention, and integration of the psychologist in the team.

CONCLUSIONS

These findings provide evidence for the suitability/acceptability, feasibility, and utility of a relaxation intervention in diabetic foot consultations.

Effects of Relaxation-Focused Nursing Program in Women with Ovarian Cancer: A Randomized Controlled Trial

BACKGROUND

Surgical treatment is a major cause of hospitalization in ovarian cancer. In this process, physical problems, such as pain and changes in respiratory functions, and psychological problems, such as anxiety and stress, may develop.

AIM

This study aims to investigate the effects of the Relaxation-Focused Nursing Program on pain, anxiety, lung volume, level of knowledge, and nursing care satisfaction in ovarian cancer surgery.

METHOD

A randomized controlled trial in which participants were randomly assigned to either the experimental (preoperative relaxation exercises and education; n = 24) or control (usual nursing care; n =22) groups. The intervention consisted of practicing four sessions of relaxation exercises and education in the hospital for two days before surgery. Data were collected using the Trait and State Anxiety Inventory, Surgical Information Form, and Perioperative Assessment Form. The results were analyzed using the Friedman and Wilcoxon tests.

RESULTS

The findings showed significant reductions in pain (p = .045) and anxiety scores (p < .001). The level of knowledge means scores were higher in the experimental group, but there was no significant difference between mean scores of spirometer volume and care satisfaction.

CONCLUSIONS

The program was more effective than usual nursing care in preoperative anxiety, pain, and level of knowledge. Although there was no difference between the care satisfaction scores of the patients, the reasons for care satisfaction were different in the program. Developing and implementing care that combines stress reduction interventions and preoperative education can improve the preoperative outcomes of patients.

The Effect of Guided Imagery on Postoperative Pain Management in Patients Undergoing Lower Extremity Surgical Operations: A Randomized Controlled Trial

Guided imagery distracts patients from disturbing feelings and thoughts, positively affects emotional well-being, and reduces pain by producing pleasing mental images. This study aimed to determine the effects of guided imagery on postoperative pain management in patients undergoing lower extremity surgery. This randomized controlled study was conducted between April 2018 and May 2019. This study included 60 patients who underwent lower extremity surgery. After using guided imagery, the posttest mean Visual Analog Scale score of patients in the intervention group was found to be 2.56 (1.00 ± 6.00), whereas the posttest mean score of patients in the control group was 4.10 (3.00 ± 6.00), and the difference between the groups was statistically significant (p <.001). Guided imagery reduces short-term postoperative pain after lower extremity surgery.

Pediatric Medical Traumatic Stress (PMTS) following Surgery in Childhood and Adolescence: a Systematic Review

The purpose of the present review was to systematically review, synthesize and quantify prevalence rates of subclinical and clinical psychological symptoms in children and adolescents who have undergone surgery. Systematic literature searches were conducted twofold in April 8, 2020 and March 7, 2021 in PsycInfo and PubMed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Manuscripts were screened against eligibility criteria and were included if they investigated psychological symptoms in children or adolescents (age between 1 to 21 years at the time of study) who were hospitalized for pediatric surgery. Means and standard deviations weighted by sample size were calculated. Eleven articles met inclusion criteria. The review revealed that a small but substantial number of children and adolescents are at an elevated risk for postoperative psychological symptoms and disorders. Up to 13% had symptoms consistent with a diagnosis of a posttraumatic stress disorder, 6% to 8% exhibited elevated symptoms of depression or anxiety, and about 25% showed internalizing and externalizing symptoms. This review provides preliminary evidence that children and adolescents experience significant psychological distress and posttraumatic stress symptoms after pediatric surgery. Apart from better training of clinicians, prevention, early psychological screening and psychosocial care in surgical wards of hospitals are recommended. Well-designed studies of high methodological quality are necessary to replicate existing findings and provide a broader base of evidence.

Effect of Ultrasound Image-Guided Nerve Block on the Postoperative Recovery Quality of Patients with Tibial Fractures Using the Concept of Enhanced Recovery after Surgery

This study was aimed at investigating the clinical effect of ultrasound-guided nerve block based on the concept of enhanced recovery after surgery (ERAS) for postoperative anesthesia in patients with tibial fractures. The noise-reduction processing was introduced in ultrasound images to adjust the ultrasound clarity of the patient. A total of 177 patients with tibial fractures in our hospital were retrospectively analyzed and divided into OG group (general anesthesia combined with nerve block, 78 cases), C1 group (simple general anesthesia, 27 cases), C2 group (ultrasound-guided nerve block combined with general anesthesia, 10 cases), and C3 group (62 cases of spinal-epidural anesthesia). The effect of anesthesia and postoperative recovery time of patients in each group were analyzed. The wake-up time of the OG group was significantly shorter than that of the other three groups (P < 0.05). The doses of propofol and remifentanil in the OG group were much lower than those in the other groups (P < 0.05). After the ultrasound image was processed with noise reduction, the image showed the lesion more clearly. The excellent and good rates of OG group, C1 group, C2 group, and C3 group were 89.86%, 62.73%, 75.37%, and 61.07%, respectively. The Ramsay sedation score and anesthesia satisfaction in the OG group were obviously higher than those in the other groups, but there was no significant difference (P > 0.05). The visual analogue scale (VAS) scores of the OG group at 12 h, 24 h, and 36 h after the surgery were 4.52 ± 0.41, 4.72 ± 0.24, and 4.81 ± 0.74, respectively, which were significantly higher than those of the other three groups (P < 0.05). On the basis of ERAS, ultrasound-guided nerve block combined with general anesthesia can improve the perioperative pain in patients with tibial fractures and significantly shorten the time for the wake-up time. In addition, it was safe and reliable, so it was worthy of clinical promotion.

A randomised pilot trial of virtual reality-based relaxation for enhancement of perioperative well-being, mood and quality of life

A cancer diagnosis and subsequent treatment can trigger distress, negatively impact coping resources, and affect well-being as well as quality of life. The aim of this pilot study was to investigate feasibility and clinical effects of a VR intervention on quality of life, well-being and mood in cancer patients undergoing surgery compared to a non-VR intervention and a control group. 54 patients with colorectal cancer or liver metastases from colorectal cancer undergoing elective curatively intended surgery were recruited and randomised to one of two intervention groups or a control group receiving standard treatment. Participants assigned to one of the intervention groups either received a VR-based intervention twice daily or listened to music twice daily. Adherence to the intervention was 64.6% in the music group and 81.6% in the VR group. The VR intervention significantly reduced heart rate (- 1.2 bpm; 95% CI - 2.24 to - 0.22; p = 0.02) and respiratory rate (- 0.7 brpm; 95% CI - 1.08 to - 0.25; p = 0.01). Self-reported overall mood improved in both groups (VR: + 0.79 pts; 95% CI 0.37-1.21; p = 0.001; music: + 0.59 pts; 95% CI 0.22-0.97; p = 0.004). There was no difference in quality of life between the three groups. Both interventions groups reported changes in feelings. Adherence rates favoured the VR intervention over the music group. Observed clinical outcomes showed stronger intragroup effects on mood, feelings, and vital signs in the VR group. The study demonstrated feasibility of a VR intervention in cancer patients undergoing surgery and should encourage further research investigating the potential of VR interventions to positively influence well-being and mood in cancer patients.

Impact of Mental Health on General Surgery Patients and Strategies to Improve Outcomes

Mental Health Disorders (MHD) are a growing concern nationwide. The significant impact MHD have on surgical outcomes has only recently started to be understood. This literature review investigated how mental health impacts the outcomes of general surgery patients and what can be done to make improvements. Patients with schizophrenia had the poorest surgical outcomes. Mental health disorders increased post-surgical pain, hospital length of stay, complications, readmissions, and mortality. Mental health disorders decreased wound healing and quality of care. Optimizing outcomes will be best accomplished through integrating more effective perioperative screening tools and interventions. Screenings tools can incorporate artificial intelligence, MHD data, resilience and its biomarkers, and patient mental health questionnaires. Interventions include cognitive behavioral therapy, virtual reality, spirituality, pharmacology, and resilience training.

Daily mother-infant skin-to-skin contact and maternal mental health and postpartum healing: a randomized controlled trial

This randomized controlled trial examined the effects of a daily hour of mother-infant skin-to-skin contact (SSC) during the first five postnatal weeks, compared to care-as-usual, on maternal depressive (primary outcome), anxiety, stress, fatigue, pain, and delivery-related post-traumatic stress symptoms (PTSS). Prenatal symptom severity and touch discomfort were examined as moderators. Mothers and full-term infants were randomly allocated to SSC or care-as-usual conditions and followed during the first postnatal year. For the total group (intention-to-treat analyses), care-as-usual mothers showed an increase of anxiety symptoms from week 2 to 12, while SSC mothers displayed a stability of anxiety symptoms. Also, care-as-usual mothers showed an initial decrease in fatigue followed by an increase, while SSC mothers showed a decrease from week 2 to 12. In per-protocol analyses, including only the SSC dyads who adhered to SSC guidelines, findings on anxiety, but not fatigue, were replicated. No SSC effects were found for depressive, stress, and pain symptoms. No moderator, dose-response, or 52-week follow-up effects were found. PTSS were low with little variation; consequently, analyses were discontinued. Daily SSC in healthy mother-infant dyads may reduce anxiety and fatigue symptoms, but not depressive, stress, and pain symptoms, during the early postpartum period. Replication studies are recommended.

Emotion Dysregulation Following Trauma: Shared Neurocircuitry of Traumatic Brain Injury and Trauma-Related Psychiatric Disorders

The psychological trauma associated with events resulting in traumatic brain injury (TBI) is an important and frequently overlooked factor that may impede brain recovery and worsen mental health following TBI. Indeed, individuals with comorbid posttraumatic stress disorder (PTSD) and TBI have significantly poorer clinical outcomes than individuals with a sole diagnosis. Emotion dysregulation is a common factor leading to poor cognitive and affective outcomes following TBI. Here, we synthesize how acute postinjury molecular processes stemming from either physical or emotional trauma may adversely impact circuitry subserving emotion regulation and ultimately yield long-term system-level functional and structural changes that are common to TBI and PTSD. In the immediate aftermath of traumatic injury, glucocorticoids stimulate excess glutamatergic activity, particularly in prefrontal cortex-subcortical circuitry implicated in emotion regulation. In human neuroimaging work, assessing this same circuitry well after the acute injury, TBI and PTSD show similar impacts on prefrontal and subcortical connectivity and activation. These neural profiles indicate that emotion regulation may be a useful target for treatment and early intervention to prevent the adverse sequelae of TBI. Ultimately, the success of future TBI and PTSD early interventions depends on the fields' ability to address both the physical and emotional impact of physical injury.

Stress-Reducing Psychological Interventions as Adjuvant Therapies for Diabetic Chronic Wounds

BACKGROUND

Diabetic foot ulcers (DFUs) are a major complication of diabetes mellitus and a leading cause of lower limb amputation. Interventions to reduce psychological stress may have the potential to improve self-care and greatly reduce the morbidity and mortality associated with DFU. This review is focused on the consequences of psychological stress in wound healing and reflects on the effects of currently used psychological stress-reducing interventions in patients with DFU, proposing new applications for currently used stress-reduction interventions.

RESULTS

Stress is a natural and fundamental survival mechanism that becomes harmful when chronic. DFU is associated with high levels of anxiety and chronic psychological stress. Chronic stressinduced cortisol and adrenaline release impair wound healing, independently of the stressor. Psychological stress-reducing interventions, such as relaxation with guided imagery, biofeedback-assisted relaxation, mindfulness-based strategies, and hypnosis, can lead to a reduction in perceived stress and improve wound healing by reducing wound inflammation and pain while improving glycemic control. All stress reduction interventions also lead to pain relief and improved patient's quality of life.

CONCLUSION

Psychological stress-reducing interventions are promising adjuvant therapies for DFU. Their clinical application can improve self-care by tackling patient's expectations, anxieties, and fears. They can also help patients manage stress and pain while reducing wound inflammation and improving wound healing.

Neural Processes of Psychological Stress and Relaxation Predict the Future Evolution of Quality of Life in Multiple Sclerosis

Health-related quality of life (HRQoL) is an essential complementary parameter in the assessment of disease burden and treatment outcome in multiple sclerosis (MS) and can be affected by neuropsychiatric symptoms, which in turn are sensitive to psychological stress. However, until now, the impact of neurobiological stress and relaxation on HRQoL in MS has not been investigated. We thus evaluated whether the activity of neural networks triggered by mild psychological stress (elicited in an fMRI task comprising mental arithmetic with feedback) or by stress termination (i.e., relaxation) at baseline (T0) predicts HRQoL variations occurring between T0 and a follow-up visit (T1) in 28 patients using a robust regression and permutation testing. The median delay between T0 and T1 was 902 (range: 363–1,169) days. We assessed HRQoL based on the Hamburg Quality of Life Questionnaire in MS (HAQUAMS) and accounted for the impact of established HRQoL predictors and the cognitive performance of the participants. Relaxation-triggered activity of a widespread neural network predicted future variations in overall HRQoL (t = 3.68, p_{family−wise error [FWE]}-corrected = 0.008). Complementary analyses showed that relaxation-triggered activity of the same network at baseline was associated with variations in the HAQUAMS mood subscale on an α_FWE = 0.1 level (t = 3.37, p_FWE = 0.087). Finally, stress-induced activity of a prefronto-limbic network predicted future variations in the HAQUAMS lower limb mobility subscale (t = −3.62, p_FWE = 0.020). Functional neural network measures of psychological stress and relaxation contain prognostic information for future HRQoL evolution in MS independent of clinical predictors.

Influence of COVID-19 pandemic on stress levels of urologic patients

Introduction

Several studies have shown the consequences of COVID-19 pandemic on perceived stress of different populations, but none of them analyzed urological patients who underwent elective surgery.

Methods

We enrolled prospectively patients who underwent elective surgery between March and October 2020. A survey on COVID-19 and the 4-item Perceived Stress Scale (PPS-4) questionnaire were administered at hospital admission. Demographic and medical history data were also collected. Uni- and multivariate analyses were performed to identify independent predictors of higher PSS-4 values (≥7).

Results

A total of 200 patients were enrolled. Mean PSS-4 value resulted 6.04. Patients with PSS-4 value ≥7 resulted 43.5% (87/200). In multivariate analysis, PSS-4 value ≥7 was independently associated (p < 0.05) with female gender (OR 6.42), oncological disease (OR 2.87), high (>5 in a range between 0 and 10) fear of intrahospital transmission of SARS-CoV-2 infection (OR 4.75), history of bladder instillation (OR 0.26), and current smokers (OR 0.27)

Conclusion

High PSS-4 values at hospital admission in urologic surgical patients are positively correlated with female gender, fear of intrahospital transmission of SARS-CoV-2 infection, and oncological disease. PSS-4 questionnaire could be useful to select patients for whom a preadmission counselling is necessary to improve the management of their high stress level.

Digital Solutions to Alleviate the Burden on Health Systems During a Public Health Care Crisis: COVID-19 as an Opportunity

The COVID-19 pandemic has generated unprecedented and sustained health management challenges worldwide. Health care systems continue to struggle to support the needs of the majority of infected individuals that are either asymptomatic or have mild symptoms. In addition, long-term effects in the form of long-lasting COVID-19 symptoms or widespread mental health issues aggravated by the pandemic pose a burden on health care systems worldwide. This viewpoint article considers aspects of digital health care solutions and how they can play an ongoing role in safely addressing gaps in the health care support available from initially and repeatedly overwhelmed providers and systems. Digital solutions can be readily designed to address this need and can be flexible enough to adapt to the evolving management requirements of various stakeholders to reduce COVID-19 infection rates, acute hospitalizations, and mortality. Multiplatform solutions provide a hybrid model of care, which can include mobile and online platforms accompanied by direct clinician input and feedback. Desirable components to be included are discussed, including symptom tracking, patient education, well-being support, and bidirectional communication between patients and clinicians. Customizable and scalable digital health platforms not only can be readily adapted to further meet the needs of employers and public health stakeholders during the ongoing pandemic, but also hold relevance for flexibly meeting broader care management needs into the future.

Comparison of Reconstructive Plastic Surgery Rates and 30-Day Postoperative Complications Between Patients With and Without Psychiatric Diagnoses

BACKGROUND

Psychiatric comorbidity is associated with greater 30-day postoperative complication rates in various surgical specialties, but is not well characterized for reconstructive plastic surgery.

OBJECTIVES

The aim of this study was to compare reconstructive plastic surgery rates and 30-day postoperative complications between patients with and without psychiatric diagnoses.

METHODS

This was a retrospective cohort study comparing patients with and without psychiatric diagnoses. Data for January 1, 2007 to December 31, 2015 were collected from the IBM MarketScan Commercial and Medicare Supplemental Databases. Rates of reconstructive plastic surgery, demographic data, covariant diagnoses, and 30-day postoperative complications were collected. Differences between the 2 groups were assessed by multivariable logistic regression.

RESULTS

Among 1,019,128 patients (505,715 with psychiatric diagnoses and 513,423 without psychiatric diagnoses) assessed, reconstructive plastic surgery rates were between 4.8% and 7.0% in those with psychiatric diagnoses, compared with 1.6% in patients without psychiatric diagnoses. The greatest odds of undergoing reconstructive plastic surgery were in patients with body dysmorphic disorder (BDD) (adjusted odds ratio [aOR], 3.16; 95% confidence interval [CI], 1.76-5.67) and anxiety disorder (aOR, 3.08; 95% CI, 2.97-3.17). When assessing 1,234,206 patients (613,400 with psychiatric diagnoses and 620,806 without psychiatric diagnoses), all of whom underwent reconstructive plastic surgery, 2-fold greater odds of any 30-day postoperative complication was associated with psychiatric diagnoses (aOR, 2.01; 95% CI, 1.28-3.11), as well as greater odds of specific complications (surgical site infection, bleeding, and hospital admission). Eating disorder diagnosis was associated with the greatest odds of a complication (aOR, 4.17; 95% CI, 3.59-4.86), followed by nasal surgery (aOR, 3.65; 95% CI, 2.74-4.89), and BDD (aOR, 3.16; 95% CI, 1.76-5.67).

CONCLUSIONS

Diagnosis of a psychiatric condition is associated with greater rates of reconstructive plastic surgery, and 2-fold greater odds of 30-day postoperative complications.

Virtual reality-based relaxation for enhancement of perioperative well-being and quality of life: protocol for a randomised pilot trial

INTRODUCTION

Patients with cancer undergoing surgery often suffer from reduced quality of life and various forms of distress. Untreated distress can negatively affect coping resources as well as surgical and oncological outcomes. A virtual reality-based stress reduction intervention may increase quality of life and well-being and reduce distress in the perioperative phase for patients with cancer. This pilot trial aims to explore the feasibility of the proposed intervention, assess patient acceptability and obtain estimates of effect to provide data for sample size calculations.

METHODS AND ANALYSIS

Patients with colorectal cancer and liver metastasis undergoing elective surgery will be recruited for this single-centre, randomised pilot trial with a three-arm design. A total of 54 participants will be randomised at 1:1:1 ratio to one of two intervention groups or a control receiving standard treatment. Those randomised to an intervention group will either receive perioperative virtual reality-based stress reduction exercises twice daily or listen to classical music twice daily. Primary feasibility outcomes are number and proportions of participants recruited, screened, consented and randomised. Furthermore, adherence to the intervention, compliance with the completion of the quality of life questionnaires and feasibility of implementing the trial procedures will be assessed. Secondary clinical outcomes are measurements of the effectiveness of the interventions to inform sample size calculations.

ETHICS AND DISSEMINATION

The study protocol, the patient information and the informed consent form have been approved by the ethics committee of the Ludwigs-Maximilians-University, Munich, Germany (Reference Number: 19-915). Study findings will be submitted for publication in peer-reviewed journals.

Effects of psychological interventions on anxiety and pain in patients undergoing major elective abdominal surgery: a systematic review

A maladaptive response to surgical stress might lead to postoperative complications. A multidisciplinary approach aimed at controlling the surgical stress response may reduce procedural complications and improve patients’ quality of life in the short and long term. Several studies suggest that psychological interventions may interact with the pathophysiology of surgical stress response, potentially influencing wound repair, innate and adaptive immunity, inflammation, perception of pain, and patients’ mood. The aim of this systematic review is to summarise the effects of perioperative psychological interventions on surgical pain and/or anxiety in adult patients scheduled for elective general abdominal and/or urologic surgery.

We conducted a systematic review of controlled clinical trials and observational studies involving psychological interventions for adult patients scheduled for elective general abdominal and/or urologic surgery. Only studies reporting pain and/or anxiety among outcome measures were included in the systematic review. The following psychological interventions were considered: (1) relaxation techniques, (2) cognitive-behavioural therapies, (3) mindfulness, (4) narrative medicine, (5) hypnosis and (6) coping strategies.

We examined 2174 papers. Among these, 9 studies were considered eligible for inclusion in this systematic review (1126 patients cumulatively): 8 are randomised controlled trials and 1 is an observational prospective pre/post study.

Psychological characteristics widely influence the pathophysiological mechanisms underlying the neuroendocrine and inflammatory response to surgical stress, potentially interfering with surgical outcomes. Psychological interventions are technically feasible and realistically applicable perioperatively during abdominal and/or urologic surgery; they influence the pathophysiological mechanisms underlying maladaptive surgical stress response and might have positive effects on patients’ surgical outcomes, such as pain and anxiety.

The Course of Posttraumatic Stress in Children: Examination of Symptom Trajectories and Predictive Factors Following Admission to Pediatric Intensive Care

OBJECTIVES

This study investigated trauma symptom trajectories of children 2-16 years old following admission to pediatric intensive care and identified factors that predicted a child's trauma symptom trajectory.

DESIGN

Prospective longitudinal design.

SETTING

Two tertiary care PICUs in Brisbane, Qld, Australia.

PATIENTS

Children 2-16 years old admitted to PICU for longer than 8 hours.

MEASUREMENTS MAIN RESULTS

Maternal reported child posttraumatic stress symptoms (n = 272) on the Trauma Symptom Checklist for Young Children were used to assess posttraumatic stress symptoms up to 12 months post admission. Semiparametric group-based trajectory analyses were completed to identify patterns over time. Age, gender, length of stay, premorbid functioning, maternal perceived threat to life, and maternal acute distress were assessed as potential risk factors. Three likely trajectory groups were identified. The majority of children were resilient (83.8%); however, a significant minority experienced chronic symptoms (12.9%) or elevated stress symptoms which resolved quickly (3.3%). After controlling for other variables, maternal report of premorbid internalizing behavior significantly predicted both chronic (odds ratio, 6.3) and recovery (odds ratio, 38.0) trajectories. Maternal acute distress significantly predicted child chronic symptom trajectories (odds ratio, 5.2).

CONCLUSIONS

Children with elevated trauma symptoms postintensive care need timely and effective intervention. The majority of children with high levels of acute symptoms will continue to have chronic, ongoing posttraumatic stress symptoms. In addition, acute maternal distress and preexisting internalizing child behavior predict ongoing psychologic distress after discharge from the PICU. Screening in the acute period post-PICU admission may identify children likely to experience ongoing chronic posttraumatic distress symptoms and enable targeted treatment of children at risk. This is the first study to examine symptom trajectories in children following pediatric intensive care admission and includes a sample of very young children.

Open-label Placebos for Wound Healing: A Randomized Controlled Trial

Background

Open-label placebos are a novel treatment option, in which participants take placebos with full knowledge that they do not contain active medicine. Open-label placebo treatments have been shown to result in patient-reported symptom improvements, but they have not been tested on objectively measurable physiological outcomes such as wound healing.

Purpose

The current study aimed to determine whether open-label placebos improved wound healing in punch biopsy wounds compared with no treatment.

Methods

In a randomized controlled trial, 70 participants (mean age 27.6 ± 10.1, 58 female) were provided with information about the beneficial effects of placebos and given a 4 mm punch biopsy wound. Participants were then randomized to either an open-label placebo intervention (two placebo tablets twice a day for 10 days) or a no-treatment control group. Wounds were photographed at 7 days and 10 days to determine reepithelialization of the wound surface.

Results

No significant differences were observed between the open-label placebo and control conditions in the percentage of wound area healed or for the number of participants with fully reepithelialized wounds at 7 days (placebo 7/32 wounds healed, control 10/33 wounds healed, (χ2[1, N = 65] = 0.60, p = .440, φ = 0.10) and 10 days after wounding (placebo 17/32, control 25/33 wounds healed (χ2[1, N = 65] = 3.64, p = .056, φ = 0.24).

Conclusions

Open-label placebo treatment does not improve the healing rate of wounds. Open-label placebos may be beneficial for subjective patient-reported outcomes but do not influence wound healing.

Efficacy of relaxation therapy as an effective nursing intervention for post-operative pain relief in patients undergoing abdominal surgery: A systematic review and meta-analysis

This systematic review and meta-analysis was conducted with the aim of assessing the efficacy of relaxation techniques for pain relief in patients undergoing abdominal surgery. The electronic search of the PubMed, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL) and Google Scholar databases was performed for studies in the English language published up to May, 2019. A total of 12 studies were included in the review and 7 in the meta-analysis. In total, 4 relaxation techniques were utilized in the included studies: Jaw relaxation, Benson's relaxation, progressive muscle relaxation (PMR) and systematic relaxation. Of the 12 included, 10 studies demonstrated statistically significant pain relief in the relaxation group as compared to the controls. The data of 422 patients in the relaxation group and 424 patients in the control group were pooled for a meta-analysis, which indicated that patients undergoing abdominal surgery had significantly greater pain relief following relaxation therapy as compared to the controls [random: standardized mean difference (SMD), −1.15; 95% CI, −2.04 to −0.26; P<0.00001). The overall quality of the studies was not high. On the whole, despite trials demonstrating the benefits of relaxation therapy for immediate pain relief in patients post-abdominal surgery, there is lack of high-quality scientific evidence substantiating its routine use. There is a need for more robust randomized control trials (RCTs) utilizing standardized relaxation protocols to provide further evidence on this subject.

Effectiveness of Stress-Reducing Interventions on the Response to Challenges to the Immune System: A Meta-Analytic Review

BACKGROUND

There is consistent evidence showing an interplay between psychological processes and immune function in health and disease processes.

OBJECTIVES

The present systematic review and meta-analysis aims to provide a concise overview of the effectiveness of stress-reducing psychological interventions on the activation of immune responses in both healthy subjects and patients.

METHODS

Included are 3 types of challenges: in vivo, in vitro, and psychophysiological. Such challenges are designed to mimic naturally occurring immune-related threats.

RESULTS

A systematic literature search was conducted using PubMed, EMBASE, and PsychInfo, resulting in 75 eligible studies. The risk of bias was assessed with the Cochrane risk-of-bias tool. Across all studies, a small-to-medium effect size was found for the effects of psychological interventions on optimization of the immune function (g = 0.33; 95% CI 0.22-0.43). While the largest effects were found for in vivo immune-related challenges (g = 0.61; 95% CI 0.34-0.88; especially on studies that incorporated skin tests and wound healing), studies incorporating psychophysiological challenges and in vitro immune-related stimulations similarly suggest more optimal immune responses among those receiving stress-reducing interventions (g = 0.28; 95% CI 0.15-0.42).

CONCLUSION

These findings showed substantial heterogeneity depending on the type of challenge, the study populations, and the intervention types. These data demonstrate support for the effectiveness of stress-reducing psychological interventions in improving immunity in studies that tested immune function by means of incorporating an in vivo,in vitro, or psychophysiological challenge. Future research should more consistently incorporate challenges into the study design to gather more insights in the mechanisms underlying the optimized immune function following a psychological intervention. This is also relevant for clinical practice, as psychological interventions can possibly supplement, or at least partially replace, current drug treatments in various somatic conditions to reduce side effects.

Guided meditation as an adjunct to enhance postoperative recovery after cardiac surgery: study protocol for a prospective randomized controlled feasibility trial

BACKGROUND

Cardiac surgical procedures are associated with postoperative neurological complications such as cognitive decline and delirium, which can complicate recovery and impair quality of life. Perioperative depression and anxiety may be associated with increased mortality after cardiac surgeries. Surgical prehabilitation is an emerging concept that includes preoperative interventions to potentially reduce postoperative complications. While most current prehabilitation interventions focus on optimizing physical health, mind-body interventions are an area of growing interest. Preoperative mind-body interventions such as Isha Kriya meditation, may hold significant potential to improve postsurgical outcomes.

METHODS

This is a prospective, randomized controlled feasibility trial. A total of 40 adult patients undergoing cardiac surgery will be randomized to one of three study groups. Participants randomized to either of the two intervention groups will receive meditative intervention: (1) commencing two weeks before surgery; or (2) commencing only from the day after surgery. Meditative intervention will last for four weeks after the surgery in these groups. Participants in the third control group will receive the current standard of care with no meditative intervention. All participants will undergo assessments using neurocognitive, sleep, depression, anxiety, and pain questionnaires at various time points in the perioperative period. Blood samples will be collected at baseline, preoperatively, and postoperatively to assess for inflammatory biomarkers. The primary aim of this trial is to assess the feasibility of implementing a perioperative meditative intervention program. Other objectives include studying the effect of meditation on postoperative pain, sleep, psychological wellbeing, cognitive function, and delirium. These will be used to calculate effect size to design future studies.

DISCUSSION

This study serves as the first step towards understanding the feasibility of implementing a mind-body intervention as a prehabilitative intervention to improve postoperative surgical outcomes after cardiac surgery.

The Influence of Preoperative Interventions on Postoperative Surgical Wound Healing in Patients Without Risk Factors: A Systematic Review

BACKGROUND

Poor wound healing and scar formation remain critical problems in daily surgical practice. Generally, most attention is paid to intra- and postoperative interventions to improve wound healing after surgery, while preoperative interventions remain unsatisfactorily explored.

OBJECTIVES

In this systematic review, the available literature on the beneficial effects of preoperative interventions on wound healing and scar formation have been summarized and compared.

METHODS

A comprehensive and systematic search has been conducted in MEDLINE, Pubmed, Embase, Web of Science, and Cochrane, supplemented by reference and citation tracking. All preoperative interventions and all clinically relevant outcome parameters have been considered for inclusion, due to the expected limited availability of literature.

RESULTS

A total of 13 studies were included, which were all randomized trials. No cohort studies or retrospective studies have been identified. All studies described different preoperative interventions and outcome parameters and could hence not be pooled and compared. Eight studies showed significantly better wound healing after a preoperative intervention. The individual studies have been summarized in this review.

CONCLUSIONS

This systemic review shows that preoperative interventions can be beneficial in improving wound healing and scar formation. In selected cases, wound healing was found to benefit from a higher preoperative body temperature, topical vitamin E application, and low patient stress levels.

LEVEL OF EVIDENCE 2

Enhanced recovery after thoracic surgery: patient information and care-plans

Many studies have confirmed that the implementation of enhanced recovery after surgery (ERAS) protocols has the advantages of reducing the potential complications after thoracic surgery and the length of hospital stay. The ERAS program involves a multidisciplinary team, aimed at integrating evidence-based knowledge into clinical practice in order to reduce the patient's stress response to the surgical procedure and improve the response to stress, guaranteeing a combination of better outcomes and cost savings. All this would not be possible without the improvement of minimally invasive surgical techniques, progression of anesthesia, pain control, and careful patient preparation. In this setting, a preoperative personal counselling may play a key role to reduce stress, fear or anxiety and improve the morbidity of patients, enabling them to achieve functional and psychological compensatory mechanisms more quickly. Preoperative patient counselling, performed using verbal, written or multimedia materials, is crucial in order to achieve the goal of the ERAS project: making the patient a potentially active participant and the main character of his recovery, able to positively impact himself throughout the surgical and healing process. This report is aimed at evaluating patient information and care-plans in thoracic surgery, reviewing the available evidence on ERAS pathways, and demonstrating our ideal program as discussed and shared among the Italian Thoracic Surgery Units accredited in the video-assisted thoracic surgery (VATS) group.

Investigating the Relationship Between Religiosity and Psychological Distress Among Surgical Inpatients: A Pilot Study

Psychological distress may hinder recovery following surgery. Studies examining the relationship between psychological distress and religiosity in the acute post-operative setting are lacking. The present study investigated this relationship, evaluated protocol design, and explored coping mechanisms. Psychological distress of surgical inpatients was assessed using the Hospital Anxiety and Depression Scale (HADS) and Rotterdam Symptom Checklist (RSCL). Religiosity was assessed using the Santa Clara Strength of Religious Faith Questionnaire. Correlations were obtained using Minitab software. Qualitative analysis identified coping mechanisms. Of eligible inpatients, 13/54 were recruited. No significant correlation was found between religiosity and psychological distress. The RSCL had a strong correlation with HADS (R = 0.82, p = 0.001). Assessment of distress was >2 min faster using RSCL compared to HADS. Relationships with pets, friends or family, and God emerged as the most common coping mechanism. Given study limitations, no conclusion was drawn regarding the relationship between religiosity and psychological distress. Weaknesses in study protocol were identified, and recommendations were outlined to facilitate the definitive study. This includes use of RSCL instead of HADS. Further study is warranted to explore how to strengthen relationships for inpatients.

The effect of Mindfulness-Based Stress Reduction on wound healing: a preliminary study

Psychological factors have been shown to influence the process of wound healing. This study examined the effect of Mindfulness-Based Stress Reduction (MBSR) on the speed of wound healing. The local production of pro-inflammatory cytokines and growth factors was studied as potential underlying mechanism. Forty-nine adults were randomly allocated to a waiting-list control group (n = 26) or an 8-week MBSR group (n = 23). Pre- and post-intervention/waiting period assessment for both groups consisted of questionnaires. Standardized skin wounds were induced on the forearm using a suction blister method. Primary outcomes were skin permeability and reduction in wound size monitored once a day at day 3, 4, 5, 6, 7, and 10 after injury. Secondary outcomes were cytokines and growth factors and were measured in wound exudates obtained at 3, 6, and 22 h after wounding. Although there was no overall condition effect on skin permeability or wound size, post hoc analyses indicated that larger increases in mindfulness were related to greater reductions in skin permeability 3 and 4 days after wound induction. In addition, MBSR was associated with lower levels of interleukin (IL)-8 and placental growth factor in the wound fluid 22 h after wound induction. These outcomes suggest that increasing mindfulness by MBSR might have beneficial effects on early stages of wound healing. Trial Registration NTR3652, http://www.trialregister.nl.

Guidelines for Perioperative Care in Bariatric Surgery: Enhanced Recovery After Surgery (ERAS) Society Recommendations

BACKGROUND

During the last two decades, an increasing number of bariatric surgical procedures have been performed worldwide. There is no consensus regarding optimal perioperative care in bariatric surgery. This review aims to present such a consensus and to provide graded recommendations for elements in an evidence-based "enhanced" perioperative protocol.

METHODS

The English-language literature between January 1966 and January 2015 was searched, with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohort studies. Selected studies were examined, reviewed and graded. After critical appraisal of these studies, the group of authors reached a consensus recommendation.

RESULTS

Although for some elements, recommendations are extrapolated from non-bariatric settings (mainly colorectal), most recommendations are based on good-quality trials or meta-analyses of good-quality trials.

CONCLUSIONS

A comprehensive evidence-based consensus was reached and is presented in this review by the enhanced recovery after surgery (ERAS) Society. The guidelines were endorsed by the International Association for Surgical Metabolism and Nutrition (IASMEN) and based on the evidence available in the literature for each of the elements of the multimodal perioperative care pathway for patients undergoing bariatric surgery.

Exploring temporal patterning of psychological skills usage during the week leading up to competition: Lessons for developing intervention programmes

Background and purpose

Although sport psychology literature focuses on psychological skills use to promote proficiency, it is still puzzling that current research has focused on psychological skills use only during competition. There remains a scarcity of empirical evidence to support the timing, and content of psychological skill application during the time preceding competition. This study examined the extent to which psychological skills usage are dynamic or stable over a 7-day pre-competitive period and whether any natural learning experiences might have accounted for the acquisition of these skills across gender and skill level.

Methods and results

Ninety elite and sub-elite table tennis players completed the Test of Performance Strategies (TOPS) at three different periods (7 days, 2 days, 1 hour) before competition. A MANOVA repeated measures with follow-up analyses revealed significant multivariate main effects for only skill level and time-to-competition with no interactions. Specifically, elite (international) athletes reported more usage than sub-elite (national) counterparts for self-talk, imagery and relaxation respectively. Time-to-competition effects showed imagery use decreased steadily across the three time points while reported usage of relaxation were almost at the same level on two time points (7 days and 1 hour) but decreased 2 days before competition.

Conclusions

Findings suggest an implementation of formalized and periodized psychological skills training programs over continuous training cycles. This may foster a positive long-term athletes’ psychological state prior to the onset of competition.

Psychological stress affects the severity of radiation-induced acute skin reactions in breast cancer patients

Psychological stress exacerbates many pathological conditions including inflammatory skin conditions. The effect of psychological stress on acute radiation-induced skin reactions has not been documented before. Here, we aimed to explore if psychological stress could aggravate skin reaction severity in breast cancer patients. We conducted a secondary analysis of patient data obtained during a randomised, controlled clinical trial for acute radiation-induced skin reaction severity in 78 breast cancer patients. Patients were assessed three times a week during treatment. Skin reaction severity was measured using the modified Radiation-Induced Skin Reaction Assessment Scale (RISRAS) and Radiation Therapy Oncology Group grades. Stress levels were determined using a 5-point LIKERT scale to rate physical well-being, managing stress levels, house, family, work and other commitments. A total of 20 patients (26%) of the 78-patient cohort were considered stressed. Skin reaction severity in stressed patients was twice that of non-stressed patients (p < 0.001) and stressed patients were five times more likely to develop moist desquamation. Our results show that psychological stress aggravates skin reaction severity during radiation therapy. This research needs to be validated in a more rigorous manner by incorporating a validated scale such as the Distress Thermometer and Impact Thermometer in future skin trials.

Effectiveness of skin-to-skin contact versus care-as-usual in mothers and their full-term infants: study protocol for a parallel-group randomized controlled trial

BACKGROUND

Twenty-to-forty percent of women experience postpartum depressive symptoms, which can affect both the mother and infant. In preterm infants, daily skin-to-skin contact (SSC) between the mother and her infant has been shown to decrease maternal postpartum depressive symptoms. In full-term infants, only two studies investigated SSC effects on maternal depressive symptoms and found similar results. Research in preterm infants also showed that SSC improves other mental and physical health outcomes of the mother and the infant, and improves the quality of mother-infant relationship. This randomized controlled trial will investigate the effects of a SSC intervention on maternal postpartum depressive symptoms and additional outcomes in mothers and their full-term infants. Moreover, two potential underlying mechanisms for the relation between SSC and the maternal and infant outcomes will be examined, namely maternal oxytocin concentrations and infant intestinal microbiota.

METHODS/DESIGN

Design: A parallel-group randomized controlled trial.

PARTICIPANTS

116 mothers and their full-term infants.

INTERVENTION

Mothers in the SSC condition will be requested to provide daily at least one continuous hour of SSC to their infant. The intervention starts immediately after birth and lasts for 5 weeks. Mothers in the control condition will not be requested to provide SSC. Maternal and infant outcomes will be measured at 2 weeks, 5 weeks, 12 weeks and 1 year after birth.

PRIMARY OUTCOME

maternal postpartum depressive symptoms. Secondary maternal outcomes: mental health (anxiety, stress, traumatic stress following child birth, sleep quality), physical health (physical recovery from the delivery, health, breastfeeding, physiological stress), mother-infant relationship (mother-infant bond, quality of maternal caregiving behavior). Secondary infant outcomes: behavior (fussing and crying, sleep quality), physical health (growth and health, physiological stress), general development (regulation capacities, social-emotional capacities, language, cognitive and motor capacities). Secondary underlying mechanisms: maternal oxytocin concentrations, infant intestinal microbiota.

DISCUSSION

As a simple and cost-effective intervention, SSC may benefit both the mother and her full-term infant in the short-and long-term. Additionally, if SSC is shown to be effective in low-risk mother-infant dyads, then thought could be given to developing programs in high-risk samples and using SSC in a preventive manner.

The effects of psychological interventions on wound healing: A systematic review of randomized trials

PURPOSE

Psychological stress has been shown to delay wound healing. Several trials have investigated whether psychological interventions can improve wound healing, but to date, this evidence base has not been systematically synthesized. The objective was to conduct a systematic review of randomized controlled trials in humans investigating whether psychological interventions can enhance wound healing.

METHODS

A systematic review was performed using PsychINFO, CINAHL, Web of Science, and MEDLINE. The searches included all papers published in English up until September 2016. The reference lists of relevant papers were screened manually to identify further review articles or relevant studies. Nineteen studies met inclusion criteria and were included in the review.

RESULTS

Fifteen of nineteen studies were of high methodological quality. Six studies were conducted with acute experimentally created wounds, five studies with surgical patients, two studies with burn wounds, two studies with fracture wounds, and four studies were conducted with ulcer wounds. Post-intervention standardized mean differences (SMD) between groups across all intervention types ranged from 0.13 to 3.21, favouring improved healing, particularly for surgical patients and for relaxation interventions. However, there was some evidence for publication bias suggesting negative studies may not have been reported. Due to the heterogeneity of wound types, population types, and intervention types, it is difficult to pool effect sizes across studies.

CONCLUSIONS

Current evidence suggests that psychological interventions may aid wound healing. Although promising, more research is needed to assess the efficacy of each intervention on different wound types. Statement of contribution What is already known on this subject? Psychological stress negatively affects wound healing. A number of studies have investigated whether psychological interventions can improve healing. However, no systematic reviews have been conducted. What does this study add? Synthesis and review of 19 trials conducted on psychological interventions and wound healing. Most evidence supports improved healing, particularly for surgical wounds and relaxation interventions. More research is needed on different intervention types with clinical wounds and into mechanisms of action.

If, Why, and When Subjective Well-Being Influences Health, and Future Needed Research

We review evidence on whether subjective well-being (SWB) can influence health, why it might do so, and what we know about the conditions where this is more or less likely to occur. This review also explores how various methodological approaches inform the study of the connections between subjective well-being and health and longevity outcomes. Our review of this growing literature indicates areas where data are substantial and where much more research is needed. We conclude that SWB can sometimes influence health, and review a number of reasons why it does so. A key open question is when it does and does not do so-in terms of populations likely to be affected, types of SWB that are most influential (including which might be harmful), and types of health and illnesses that are most likely to be affected. We also describe additional types of research that are now much needed in this burgeoning area of interest, for example, cross-cultural studies, animal research, and experimental interventions designed to raise long-term SWB and assess the effects on physical health. This research area is characterised both by potentially extremely important findings, and also by pivotal research issues and questions.

Stress, Illness Perceptions, Behaviors, and Healing in Venous Leg Ulcers: Findings From a Prospective Observational Study

OBJECTIVE

The aim of the study was to investigate the impact of stress, illness perceptions, and behaviors on healing of venous leg ulcers.

METHODS

A prospective observational study of 63 individuals for 24 weeks investigated possible psychosocial predictors of healing. There were two indices of healing: rate of change in ulcer area and number of weeks to heal. Psychological variables were assessed at baseline using self-report measures (Perceived Stress Scale, Hospital Anxiety and Depression Scale, Revised Illness Perception Questionnaire, adapted Summary of Diabetes Self-Care Activities, Adherence Questionnaire, and Short-Form Health Survey).

RESULTS

Controlling for sociodemographic and clinical variables, for the 24 weeks, a slower rate of change in ulcer area was predicted by greater stress (standardized β = -0.61, p = .008), depression (standardized β = -0.51, p = .039), and holding negative perceptions or beliefs about the ulcer (standardized β = -1.4, p = .045). By 24 weeks, 69% of ulcers had closed. A more negative emotional response to the ulcer at baseline (i.e., emotional representation of the ulcer) was associated with a greater number of weeks to heal (hazard ratio [HR] = 0.63, 95% confidence interval [CI] = 0.41-0.95, p = .028). Higher educational attainment (HR = 3.22, 95% CI = 1.37-7.55, p = .007) and better adherence to compression bandaging (HR = 1.41, 95% CI = 1.06-1.88, p = .019) were associated with fewer weeks to heal. No other psychosocial variable (stress, perceptions about the ulcer, health behaviors) predicted weeks to heal.

CONCLUSIONS

Alongside ulcer-related predictors, psychological and sociodemographic factors were associated with healing. Future research should explore mediating mechanisms underlying these associations and develop interventions to target these variables.

How financial strain affects health: Evidence from the Dutch National Bank Household Survey

The mechanisms by which financial strain affects health are not well understood. In this paper, we conduct a longitudinal mediation analysis of the Dutch National Bank Household Survey. To quantify the relative importance of biological and nonbiological pathways from financial strain to health, we consider smoking, heavy drinking and being overweight as plausible behavioural responses to financial strain but find that only 4.9% of the response of self-reported health to financial strain is mediated by these behaviours. Further analysis indicates that although financial strain increases impulsivity this has little effect on unhealthy behaviours. Economic stresses therefore appear to be distinct from other forms of stress in the relatively minor influence of nonbiological pathways to ill-health.

Psychological preparation and postoperative outcomes for adults undergoing surgery under general anaesthesia

BACKGROUND

In a review and meta-analysis conducted in 1993, psychological preparation was found to be beneficial for a range of outcome variables including pain, behavioural recovery, length of stay and negative affect. Since this review, more detailed bibliographic searching has become possible, additional studies testing psychological preparation for surgery have been completed and hospital procedures have changed. The present review examines whether psychological preparation (procedural information, sensory information, cognitive intervention, relaxation, hypnosis and emotion-focused intervention) has impact on the outcomes of postoperative pain, behavioural recovery, length of stay and negative affect.

OBJECTIVES

To review the effects of psychological preparation on postoperative outcomes in adults undergoing elective surgery under general anaesthetic.

SEARCH METHODS

We searched the Cochrane Register of Controlled Trials (CENTRAL 2014, Issue 5), MEDLINE (OVID SP) (1950 to May 2014), EMBASE (OVID SP) (1982 to May 2014), PsycINFO (OVID SP) (1982 to May 2014), CINAHL (EBESCOhost) (1980 to May 2014), Dissertation Abstracts (to May 2014) and Web of Science (1946 to May 2014). We searched reference lists of relevant studies and contacted authors to identify unpublished studies. We reran the searches in July 2015 and placed the 38 studies of interest in the `awaiting classification' section of this review.

SELECTION CRITERIA

We included randomized controlled trials of adult participants (aged 16 or older) undergoing elective surgery under general anaesthesia. We excluded studies focusing on patient groups with clinically diagnosed psychological morbidity. We did not limit the search by language or publication status. We included studies testing a preoperative psychological intervention that included at least one of these seven techniques: procedural information; sensory information; behavioural instruction; cognitive intervention; relaxation techniques; hypnosis; emotion-focused intervention. We included studies that examined any one of our postoperative outcome measures (pain, behavioural recovery, length of stay, negative affect) within one month post-surgery.

DATA COLLECTION AND ANALYSIS

One author checked titles and abstracts to exclude obviously irrelevant studies. We obtained full reports of apparently relevant studies; two authors fully screened these. Two authors independently extracted data and resolved discrepancies by discussion.Where possible we used random-effects meta-analyses to combine the results from individual studies. For length of stay we pooled mean differences. For pain and negative affect we used a standardized effect size (the standardized mean difference (SMD), or Hedges' g) to combine data from different outcome measures. If data were not available in a form suitable for meta-analysis we performed a narrative review.

MAIN RESULTS

Searches identified 5116 unique papers; we retrieved 827 for full screening. In this review, we included 105 studies from 115 papers, in which 10,302 participants were randomized. Mainly as a result of updating the search in July 2015, 38 papers are awaiting classification. Sixty-one of the 105 studies measured the outcome pain, 14 behavioural recovery, 58 length of stay and 49 negative affect. Participants underwent a wide range of surgical procedures, and a range of psychological components were used in interventions, frequently in combination. In the 105 studies, appropriate data were provided for the meta-analysis of 38 studies measuring the outcome postoperative pain (2713 participants), 36 for length of stay (3313 participants) and 31 for negative affect (2496 participants). We narratively reviewed the remaining studies (including the 14 studies with 1441 participants addressing behavioural recovery). When pooling the results for all types of intervention there was low quality evidence that psychological preparation techniques were associated with lower postoperative pain (SMD -0.20, 95% confidence interval (CI) -0.35 to -0.06), length of stay (mean difference -0.52 days, 95% CI -0.82 to -0.22) and negative affect (SMD -0.35, 95% CI -0.54 to -0.16) compared with controls. Results tended to be similar for all categories of intervention, although there was no evidence that behavioural instruction reduced the outcome pain. However, caution must be exercised when interpreting the results because of heterogeneity in the types of surgery, interventions and outcomes. Narratively reviewed evidence for the outcome behavioural recovery provided very low quality evidence that psychological preparation, in particular behavioural instruction, may have potential to improve behavioural recovery outcomes, but no clear conclusions could be reached.Generally, the evidence suffered from poor reporting, meaning that few studies could be classified as having low risk of bias. Overall,we rated the quality of evidence for each outcome as 'low' because of the high level of heterogeneity in meta-analysed studies and the unclear risk of bias. In addition, for the outcome behavioural recovery, too few studies used robust measures and reported suitable data for meta-analysis, so we rated the quality of evidence as `very low'.

AUTHORS' CONCLUSIONS

The evidence suggested that psychological preparation may be beneficial for the outcomes postoperative pain, behavioural recovery, negative affect and length of stay, and is unlikely to be harmful. However, at present, the strength of evidence is insufficient to reach firm conclusions on the role of psychological preparation for surgery. Further analyses are needed to explore the heterogeneity in the data, to identify more specifically when intervention techniques are of benefit. As the current evidence quality is low or very low, there is a need for well-conducted and clearly reported research.
