Effects of Laughter Therapy on Improving Negative Emotions Associated with Cancer: A Systematic Review and Meta-Analysis

INTRODUCTION

With aging and growth of the population, the risk of cancer incidence and mortality is rapidly increasing. However, psychosocial treatment has been seriously neglected in many healthcare settings. Laughter therapy is a therapeutic program to improve emotional wellbeing and health which has been applied as a complementary treatment. We aim to explore effects of laughter therapy for patients with cancer on their negative emotions such as depression, anxiety, stress, pain, and fatigue.

METHODS

We searched the Cochrane Library, Embase, PubMed, Scopus, Web of Science, WANFANG data, Weipu (VIP), Chinese National Knowledge Infrastructure (CNKI) and independently rated the risk of bias in every article using the Cochrane Collaboration's Risk of Bias Assessment Tool. Review Manager and STATA software were used to pool the individually included studies.

RESULTS

Seven studies were found eligible to be included in the present review. Overall, study quality was relatively high. Our findings suggest that laughter therapy might have a positive effect on improving emotional response in cancer patients. Arguably, laughter therapy, whether humor or laughter, has a positive effect on anxiety, stress, pain feeling, fatigue, and depression in cancer patients.

CONCLUSIONS

Laughter therapy is a convenient, multi-modality, flexible-duration therapy to improve negative emotions in cancer patients, regardless of their gender, age, and type of cancer.

Treatment of Cancer Pain: A Systematic Review

CONTEXTUALIZATION

One of the biggest problems regarding the treatment of cancer patients is pain, whether due to the cancer or the treatment itself. Therefore, there is a search for treatments that aims to promote an effective treatment in this sense.

PURPOSE

This article aims to verify which are the recent methods used to treat pain in cancer patients in a multidisciplinary sense, and to evaluate their effectiveness.

METHODOLOGY

Systematic reviews, meta-analyses and randomized clinical trials utilizing the LILACS, NCBI, and MEDLINE platforms of the last 5 years were included. The descriptors were pain treatment in oncology, pain management, complementary therapies, and other synonyms, in Portuguese, English and Spanish. This included any technique that was effective in the treatment of cancer pain.

RESULTS

The initial search found 2246 articles, of which 22 were included in the systematic review. Most of these are acupuncture treatments, opioids versus anti-inflammatories versus analgesics, radiotherapy, behavioral therapies, among others. Most articles suggest benefits with these therapies, improved quality of life for patients and tolerable side effects.

CONCLUSION

This study demonstrates the effectiveness of the current methods used in the treatment of pain in cancer patients so that professionals in the area can have more options for treating cancer pain. Despite the important limitations, the guideline for further research and the situations in which treatments have shown effectiveness are present in it.

Environmental Enrichment in Postoperative Pain and Surgical Care: Potential Synergism With the Enhanced Recovery After Surgery Pathway

BACKGROUND

Holistic biopsychosocial care has been underemphasized in perioperative pathway designs. The importance and a cost-effective way of implementing biopsychosocial care to improve postoperative pain and facilitate surgical convalescence are not well established, despite the recent popularization of Enhanced Recovery After Surgery (ERAS) programs.

OBJECTIVE

We have explored the evidence and rationale of environmental enrichment (EE) as a complementary multimodal psychosocial care pathway to reduce postoperative pain, optimize patient recovery and improve existing weaknesses in surgical care.

METHODS

We conducted a database search to identify and grade potential EE techniques for their evidence quality and consistency in the management of acute postoperative pain, perioperative anxiety and the etiologically comparable acute procedural or experimental pain.

FINDINGS AND CONCLUSIONS

The introduction of music, virtual reality, educational information, mobile apps, or elements of nature into the healthcare environment can likely improve patients' experience of surgery. Compared with traditional psychological interventions, EE modalities are voluntary, therapist-sparing and more economically sustainable. We have also discussed practical strategies to integrate EE within the perioperative workflow. Through a combination of sensory, motor, social and cognitive modalities, EE is an easily implementable patient-centered approach to alleviate pain and anxiety in surgical patients, create a more homelike recovery environment and improve quality of life.
