Adjuvant music therapy for patients with hypertension: a meta-analysis and systematic review

The impact of music on anxiety, pain, and blood pressure in ophthalmic surgery: A systematic review and meta-analysis

OBJECTIVES

To evaluate the effectiveness of music therapy in reducing anxiety, pain, and vital sign changes in ophthalmic surgery patients.

METHODS

An extensive search of databases, including PubMed, Embase, Cochrane, Web of Science, and Google Scholar, identified relevant studies up to Jan 2024. Selection of studies was conducted based on the PICOS criteria. The quality of methodology was assessed using the Cochrane risk-of-bias assessment tool and Review Manager 5.4. Meta-analysis comparing the control group and the music therapy group was performed using R and Stata/SE 15.1 random or fixed effects model.

RESULTS

This meta-analysis included fifteen studies comprising 2098 participants. The analysis revealed that music therapy significantly reduced the risk of high anxiety levels as measured by Visual Analogue Scale (VAS) (I2 = 0 %, RR(95 %CI): 0.75(0.63, 0.88), p = 0.0006), indicating a substantial effect without heterogeneity. The Anxiety scores determined by State-Trait Anxiety Inventory-State (STAI-S) also showed a significant decrease (SMD(95 %CI): -0.75(-0.88, -0.61), p < 0.0001), albeit with moderate heterogeneity (I² = 36 %). Additionally, music therapy was associated with a reduction in intraoperative pain levels, with no observed heterogeneity (I2 = 0 %, SMD(95 %CI): -0.74(-0.93, -0.56), p < 0.0001). In contrast, music intervention did not significantly influence self-reported nervousness, relaxation, or satisfaction levels as determined by VAS. Regarding to physiological parameters, a marginal decrease in systolic blood pressure (SBP) was observed (SMD(95 %CI): -0.42(-0.79, -0.04), p = 0.0286), with considerable heterogeneity (I² = 92 %). Diastolic blood pressure (DBP) experienced a slight reduction (I² = 90 %, SMD(95 %CI): -0.45(-0.79, -0.11), p = 0.0088). However, no significant effect was observed on patients' heart rate (p = 0.0864).

CONCLUSION

Music therapy effectively reduced anxiety and pain, and moderately improved vital signs in patients undergoing ophthalmic surgery, highlighting its role in enhancing patient well-being. Further in-depth RCTs are needed to confirm its efficacy.

The psychophysiology of music-based interventions and the experience of pain

In modern times there is increasing acceptance that music-based interventions are useful aids in the clinical treatment of a range of neurological and psychiatric conditions, including helping to reduce the perception of pain. Indeed, the belief that music, whether listening or performing, can alter human pain experiences has a long history, dating back to the ancient Greeks, and its potential healing properties have long been appreciated by indigenous cultures around the world. The subjective experience of acute or chronic pain is complex, influenced by many intersecting physiological and psychological factors, and it is therefore to be expected that the impact of music therapy on the pain experience may vary from one situation to another, and from one person to another. Where pain persists and becomes chronic, aberrant central processing is a key feature associated with the ongoing pain experience. Nonetheless, beneficial effects of exposure to music on pain relief have been reported across a wide range of acute and chronic conditions, and it has been shown to be effective in neonates, children and adults. In this comprehensive review we examine the various neurochemical, physiological and psychological factors that underpin the impact of music on the pain experience, factors that potentially operate at many levels - the periphery, spinal cord, brainstem, limbic system and multiple areas of cerebral cortex. We discuss the extent to which these factors, individually or in combination, influence how music affects both the quality and intensity of pain, noting that there remains controversy about the respective roles that diverse central and peripheral processes play in this experience. Better understanding of the mechanisms that underlie music's impact on pain perception together with insights into central processing of pain should aid in developing more effective synergistic approaches when music therapy is combined with clinical treatments. The ubiquitous nature of music also facilitates application from the therapeutic environment into daily life, for ongoing individual and social benefit.

Efficacy and acceptability of music therapy for post-traumatic stress disorder: a systematic review and meta-analysis of randomized controlled trials

Background: Music therapy is increasingly examined in randomized controlled trials (RCTs) and shows potential in treating post-traumatic stress disorder (PTSD).Objective: This systematic review and meta-analysis critically evaluates the current clinical evidence supporting the efficacy and acceptability of music therapy for PTSD.Method: RCTs comparing music therapy in addition to care as usual (CAU) versus either CAU alone or CAU combined with standard psychotherapy/pharmacotherapy for PTSD were retrieved from major English - and Chinese-language databases. Standardized mean differences (SMDs) for post-treatment PTSD symptom scores and risk differences (RDs) for retention rates upon treatment completion were calculated to assess the efficacy and acceptability of music therapy, respectively. The Cochrane risk of bias (RoB) tool 2.0 and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) were used to assess the RoB of included studies and certainty of the evidence, respectively.Results: Nine studies, incorporating 527 PTSD patients, were included, all with high RoB. The post-treatment PTSD symptom scores were significantly lower in the music therapy group than the inactive control group (SMD = -1.64, P < .001), but comparable between the music therapy group and the active control group (SMD = -0.28, P = .330). The retention rates did not differ significantly between the music therapy group and both control groups (RD = 0.03, P = .769; RD = 0.16, P = .829). The GRADE rated certainty level of evidence as low.Conclusions: Although meta-analytic findings suggest that music therapy is effective in reducing post-traumatic symptoms in individuals with PTSD, with its therapeutic effect comparable to that of standard psychotherapy, the low level of certainty limits its generalizability. More methodologically stringent studies are warranted to strengthen the clinical evidence for the efficacy and acceptability of music therapy for PTSD.

Evidence on the use of alternative substances and therapies in hypertension

OBJECTIVE

Review of some of the best-known biological and non-biological complementary/alternative therapies/medicines (CAM) and their relationship with blood pressure (BP) and hypertension (HT).

SEARCH STRATEGY

Narrative review assessing a recent series of systematic reviews, meta-analyses, and clinical trials published in recent years, focusing on the effects of CAM on BP and HT.

SELECTION OF STUDIES

We searched EMBASE, MEDLINE, Cochrane Library and Google Scholar, obtaining a total of 4336 articles, finally limiting the search to 181 after applying filters.

SYNTHESIS OF RESULTS

Some studies on biological therapies show some usefulness in BP reduction with an adequate benefit-risk balance, although there is a scarcity of high-quality trials that support these results. Some mind-body therapies have shown hypothetical benefit; in contrast, others lack robust evidence.

CONCLUSIONS

Although some therapies present a reasonable risk-benefit ratio, they should in no case replace pharmacological treatment when indicated.

Effects of live music during hemodialysis treatments in pediatric patients

BACKGROUND

Engaging chronically ill pediatric patients with live music has been associated with improved physiological and psychological well-being. However, the impact of live music during hemodialysis treatments has yet to be assessed, in particular in pediatric patients. This study focuses on the effects of live music therapy during chronic hemodialysis treatment.

METHODS

An experimental design with randomization was applied in this pilot study. A total of 16 participants with kidney failure requiring hemodialysis participated in the study. In addition to their usual care (N = 96 measurements), the patients in the experimental group listened to 30 min of live music during their hemodialysis procedure. The control group was observed for 30 min while they received their usual care (N = 96 measurements) and were exposed to a series of animated videos that were broadcast in the common room where hemodialysis treatment is performed. Data concerning heart rate, blood pressure, and levels of depression and anxiety were collected for analysis.

RESULTS

Live music significantly reduced heart rate (p < 0.05), systolic pressure (p < 0.05) and diastolic pressure (p < 0.05). The findings also highlighted that, after listening to live music, there was a significant decrease in anxiety and depression (p < 0.05).

CONCLUSIONS

In our small study sample, live music improved some physiological and psychological indices in pediatric hemodialysis patients. Further research evaluating larger samples with longitudinal follow-up is required.
