Impact of nonpharmacological interventions on cognitive impairment in women with breast cancer: A systematic review and meta-analysis.

ABSTRACT:

Objective

This study aimed to examine the characteristics of research conducted on nonpharmacological interventions for cognitive impairment in patients with breast cancer and identify the primary effects of nonpharmacological interventions through a systematic review and meta-analysis.

Methods

Five electronic databases were searched to identify all randomized controlled trial studies until September 30, 2022, using the key terms "breast cancer," "cognitive disorders," and their possible variations. The Cochrane Risk of Bias tool was used to assess risk of bias. The effect sizes were calculated in Hedges' g. Potential moderators influencing the intervention effects were explored.

Results

Twenty-three studies were included in the systematic review, and 17 studies were included in the meta-analysis. Among the nonpharmacological interventions for patients with breast cancer, cognitive rehabilitation and physical activity were the most common, followed by cognitive behavioral therapy. The meta-analysis indicated that nonpharmacological interventions had a significant effect on attention (g = 0.83; 95% CI: 0.14 to 1.52; I ² = 76%), immediate recall (g = 0.33; 95% CI: 0.18 to 0.49; I ² = 0%), executive function (g = 0.25; 95% CI: 0.13 to 0.37; I ² = 0%), and processing speed (g = 0.44; 95% CI: 0.14 to 0.73; I ² = 51%) among objective cognitive functions, as well as subjective cognitive function (g = 0.68; 95% CI: 0.40 to 0.96; I ² = 78%). Intervention type and mode of delivery were potential moderators for the effects of nonpharmacological interventions on cognitive functions.

Conclusions

Nonpharmacological interventions can improve subjective and objective cognitive functioning among patients with breast cancer undergoing cancer treatment. Therefore, it is necessary to provide nonpharmacological interventions by screening patients at high risk of cancer-related cognitive impairment.

Project description:At present, prevention is particularly important when there is no effective treatment for cognitive decline. Since the adverse events of pharmacological interventions counterbalance the benefits, nonpharmacological approaches seem desirable to prevent cognitive decline. To our knowledge, no meta-analyses have been published on nonpharmacological interventions preventing cognitive decline. To investigate whether nonpharmacological interventions play a role in preventing cognitive decline among older people, we searched related trials up to March 31, 2019, in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials and the Cochrane library databases. Randomized controlled trials (RCTs) were included if they enrolled participants older than 60 years of age who had a risk of cognitive decline, and the interventions were nonpharmacological. Two reviewers independently extracted data and assessed study quality. The Grading of Recommendations Assessment Development and Evaluation (GRADE) approach was used to rate the quality of evidence. Heterogeneity was quantified with I2. Subgroup analysis and meta-regression were used to research the sources of heterogeneity. Influence analyses were used to detect and remove extreme effect sizes (outliers) in our meta-analysis. Publication bias was assessed with funnel plots and Egger test. Primary outcomes were the incidence of mild cognitive impairment (MCI) or dementia and Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) scores. Second outcomes were activities of daily living (ADL) and Mini-Mental State Examination (MMSE) scores. A total of 22 studies with 13,264 participants were identified for analysis. In terms of prevention, nonpharmacological interventions appeared to be more effective than control conditions, as assessed by the incidence of MCI or dementia (RR, 0.73; CI, 0.55-0.96; moderate-certainty evidence), while the results of ADAS-Cog suggested no significant differences between two groups (MD, -0.69; CI, -1.52-0.14; very low-certainty evidence). Second outcomes revealed a significant improvement from nonpharmacological interventions versus control in terms of the change in ADL (MD, 0.73; CI, 0.65-0.80) and MMSE scores (posttreatment scores: MD, 0.25; CI, 0.02-0.47; difference scores: MD, 0.59, CI, 0.29-0.88). Univariable meta-regression showed association between lower case of MCI or dementia and two subgroup factors (P = 0.013 for sample size; P = 0.037 for area). Multiple meta-regression suggested that these four subgroup factors were not associated with decreased incidence of MCI (P > 0.05 for interaction). The Naive RR estimate was calculated as 0.73. When the three studies that detected by outlier and influence analysis were left out, the Robust RR was 0.66. In conclusion, nonpharmacological therapy could have an indicative role in reducing the case of MCI or dementia. However, given the heterogeneity of the included RCTs, more preregistered trials are needed that explicitly examine the association between nonpharmacological therapy and cognitive decline prevention, and consider relevant moderators.

Project description:Background and objectivesGate control theory and fear-avoidance model of chronic pain posit that biopsychosocial factors can modulate pain. Nonpharmacological interventions are recommended in managing chronic pain, but little information is available regarding their efficacy in older adults. We examined and compared the efficacy of different nonpharmacological intervention approaches for chronic pain management among older adults via meta-analysis and subgroup analysis.Research design and methodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO number CRD42020222767), a systematic search was undertaken using MEDLINE, Embase, and PsycINFO up to March 21, 2022. Randomized controlled trials were included, and data were pooled using a random-effects meta-analysis model. Risk of bias was assessed using a quality rating scale for psychological interventions.ResultsTwenty-five trials (N = 2,394 participants) were identified. Six types of nonpharmacological interventions were compared with control conditions (sham/attention control and treatment as usual). Nonpharmacological interventions were associated with significant reductions in pain intensity, pain interference, depressive symptoms, catastrophizing beliefs, and improvement in physical performance (standardized mean differences -0.34 to 0.54). Subgroup analyses based on different nonpharmacological approaches revealed the benefits of psychological approaches combined with physical activity.Discussion and implicationsNonpharmacological interventions, particularly those adopting psychological approaches and physical activity, have a small but statistically significant effect on chronic pain management in older adults. Reduction in pain interference may be related to reduced catastrophizing beliefs, thus providing support for the fear-avoidance model. Further research with adequate power is needed to establish the efficacy and mechanism of various intervention modalities for older adults.

Project description:BACKGROUND:Many reviews with conflicting findings on dementia caregiver interventions have been published. A meta-review was conducted to synthesize the findings of systematic reviews and meta-analyses. METHODS:MEDLINE, PsycINFO, CINAHL and Cochrane Library were searched to identify reviews published during 2006-2018. RESULTS:Sixty reviews covering >?500 intervention studies were selected and appraised with Assessment of Multiple Systematic Reviews (AMSTAR) II. The great majority of studies were of low quality according to AMSTAR II, but quality factors appeared unrelated to the conclusions obtained. Depression was most modifiable, with effects found across a spectrum of interventions (psychoeducation, counseling/psychotherapy, occupational therapy, mindfulness-based interventions, multicomponent interventions, etc.). Evidence of intervention effect was also found for quality of life (psychoeducation), mastery (psychoeducation, occupational therapy and multicomponent interventions) and communication skills (communication training). Null or weak results were found for anxiety, social support and burden. Support groups and respite were generally ineffective. There was no evidence that dyadic programs were better than caregiver-only programs, or that programs delivered individually or in groups would differ in their impacts. The evidence also does not support multicomponent interventions to have broader impacts than single-component programs. Methodological issues in the existing reviews (e.g., selective use of studies to serve different research purposes and inconsistent classification of interventions) were noted and taken into account when interpreting findings. CONCLUSIONS:This meta-review clarified variations in review methodology and identified a few potent groups of intervention (most notably psychoeducation, psychotherapy, occupational therapy, and multicomponent interventions), although no intervention type had broad effects on caregiver outcomes. We note that improvements are needed in the reporting of intervention studies and in making the classification of interventions more transparent and consistent. We further recommend fewer and larger-scale reviews and more attention to positive outcomes in order to better inform the field. Developing interventions with broader impacts and packaging them to meet caregivers' changing needs in the course of dementia should be a priority for researchers and practitioners.

Project description:ImportanceAdequate sleep duration is necessary for many aspects of child health, development, and well-being, yet sleep durations for children are declining, and effective strategies to increase sleep in healthy children remain to be elucidated.ObjectiveTo determine whether nonpharmaceutical interventions to improve sleep duration in healthy children are effective and to identify the key components of these interventions.Data sourcesCENTRAL, MEDLINE, Embase, PsycINFO, Web of Science Core collection, ClinicalTrials.gov, and WHO trials databases were searched from inception to November 15, 2021.Study selectionRandomized clinical trials of interventions to improve sleep duration in healthy children were independently screened by 2 researchers. A total of 28 478 studies were identified.Data extraction and synthesisData were processed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guideline. Random-effects meta-analytic models were used to estimate pooled effect sizes.Main outcomes and measuresDifference in sleep duration, measured in minutes.ResultsA total of 13 539 child participants from 45 randomized clinical trials were included. Of these, 6897 (50.9%) were in the intervention group and 6642 (49.1%) in the control group, and the mean age ranged from 18 months to 19 years. Pooled results indicate that sleep interventions were associated with 10.5 minutes (95% CI, 5.6-15.4) longer nocturnal sleep duration. There was substantial variation between trials. Sources of variation that were not associated with the study effect size included age group, whether the population was identified as having a sleep problem or being at a socioeconomic disadvantage (eg, coming from a low-income family or area), method of assessment of sleep duration (objective vs subjective), location of intervention delivery (home vs school), whether interventions were delivered in person or used parental involvement, whether behavioral theory was used, environmental change, or had greater or lower intensity. Interventions that included earlier bedtimes were associated with a 47-minute sleep extension (95% CI, 18.9-75.0; 3 trials) compared with remaining studies (7.4 minutes; 95% CI, 2.9-11.8; 42 trials) (P = .006 for group difference). Trials of shorter duration (6 months or less) had larger effects.Conclusions and relevanceInterventions focused on earlier bedtimes may offer a simple, pragmatic, effective way to meaningfully increase sleep duration that could have important benefits for child health.

Project description:BackgroundSelective mutism (SM) is an anxiety disorder that often starts in early years with serious and lasting consequences. Nonpharmacological interventions are commonly seen as the preferred first treatment. This systematic review identifies outcome measures used and outcomes achieved for nonpharmacological interventions for children and adolescents with SM.MethodsSystematic searches were conducted using 13 electronic databases and hand searches, including peer-reviewed and grey literature since 1992.ResultsTwenty-five studies were identified. While specific measures varied, all studies reported an outcome measure for speaking behaviour and 18 used a measure of anxiety. Few studies reported measures of SM remission (k = 6), well-being (k = 6), academic impact (k = 2), or quality of life (k = 1). Within subject outcomes for nonpharmacological interventions were variable for improvements in speaking behaviours (very small to large positive effects) and reduction in anxiety symptoms (very small negative to large positive effects). Only five randomised controlled trials (RCTs) were included in the meta-analysis. Three studies compared a combined systems/behavioural approach with waitlist controls indicating a significant and large effect (Hedges g = 1.06, p < .0001, 95% CI: 0.57-1.56) on improved speaking behaviour. Two of these RCTs showed a large effect for SM remission favouring the intervention (Risk Ratio = 4.25, p = .1774, 95% CI: 0.52-34.84) but this did not reach statistical significance. Non-significant outcomes for two RCTs with active controls (Hedges g = 0.55, p < .2885, 95% CI: -0.47 to 1.57) showed considerable heterogeneity in approach and outcomes, one with large and one with negligible effects.ConclusionDespite the considerable impairment caused by SM, there has been little systematic evaluation of non-pharmacological interventions. Although combined systems/behavioural interventions are promising, further systematic evaluations are urgently needed to inform treatment approaches. Cross-study measurement harmonisation is required to promote learning from all studies, including wider clinical and economic outcomes.Clinical trial registrationNot applicable.

Project description:ObjectiveWeb-based rehabilitation, a branch of telerehabilitation, is carried out over the internet, unrestricted by time or place. Even though web-based interventions have been reported as feasible and effective in cases of mood disorders, for example, such evidence on the effectiveness of web-based cognitive rehabilitation remains unclear. This systematic review summarizes current knowledge on web-based psychoeducational programs aiming to manage cognitive deficits in patients with diseases that affect cognition.MethodsUsing the Ovid database and the Web of Science, we systematically searched the Cochrane Database of Systematic Reviews, Medline, and PsycINFO to identify eligible studies. The review protocol (CRD42021257315) was pre-registered with the PROSPERO International Prospective Register of Systematic Reviews. The search was performed 10/13/2022. Two reviewers independently screened titles, abstracts, and full-texts, and extracted data for the selected studies. Two independent reviewers assessed the methodological quality.ResultsThe search retrieved 6,487 articles. Four studies with different patient groups (stroke, traumatic brain injury, brain tumor, and cancer) met the inclusion criteria of this systematic review. The studies examined systematic cognition-focused psychoeducational rehabilitation programs in which the patient worked independently. Three studies found positive effects on subjective cognitive functions, executive functions, and self-reported memory. No effects were found on objective cognitive functions. However, the studies had methodological weaknesses (non-randomized designs, small sample sizes, vaguely described interventions). Overall, adherence and patient satisfaction were good/excellent.ConclusionWeb-based cognitive intervention programs are a new approach to rehabilitation and patient education. The evidence, although scarce, shows that web-based interventions are feasible and support subjective cognitive functioning. However, the literature to date is extremely limited and the quality of the studies is weak. More research with high-quality study designs is needed.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=257315, identifier: CRD42021257315.
