The prevalence of burnout in oncology professionals: an overview of systematic reviews with meta-analyses including more than 90 distinct studies.

PURPOSE: This overview of reviews aimed to summarize the prevalence of burnout and the dimensions of burnout (emotional exhaustion, depersonalization, and personal accomplishment) in oncology professionals around the world. METHODS: The CINAHL, Embase, PsycINFO, and PubMed databases were searched from inception to September 13, 2023. AMSTAR 2 was used to assess the quality of reviews. The overlap between reviews was calculated. RESULTS: Twelve reviews were included. Overall, reviews showed that burnout was prevalent in oncologists and oncology nurses. On the other hand, no reviews meta-analyzed the prevalence of burnout in oncology radiation therapists. In addition, the dimensions of burnout, high emotional exhaustion, high depersonalization, and low personal accomplishment were highly prevalent across reviews in oncologists, oncology nurses, and oncology radiation therapists. In oncologists, the Americas (specifically Canada) showed the highest prevalence rates for high emotional exhaustion, whereas high depersonalization and low personal accomplishment were mainly prevalent in Europe and Asia, respectively. In oncology nurses, high emotional exhaustion and high depersonalization were mainly prevalent in Asia, whereas low personal accomplishment was more prevalent in the Americas (specifically Canada). The prevalence of overall levels of burnout was not meta-analyzed by continents. CONCLUSION: Some methodological improvements may help to make more robust the findings of this overview (e.g., specific subgroup meta-analyses by oncology specialties), which may help readers reach more precise, direct, and consistent findings.

Psoriatic arthritis with psychological comorbidities: an overview of systematic reviews on incidence, prevalence, and geographic disparities.

Systematic reviews and meta-analysis evaluating the prevalence, incidence, and psychological comorbidities of psoriatic arthritis (PsA) are increasing, so it's time to perform an overview of systematic reviews. To summarize the pooled prevalence, incidence, and psychological comorbidities rates of PsA, and to explore possible continent disparities. In this overview of systematic reviews the CINAHL, EMBASE, PsycINFO, and PubMed were searched to October 25, 2023. This overview included systematic reviews with meta-analysis of people with PsA, providing the pooled prevalence or incidence rates of PsA in general, or clinical populations and/or psychological comorbidities. The Preferred Reporting Items for Overviews of Reviews (PRIOR) statement was followed. AMSTAR-2 assessed the quality of reviews. The degree of overlap was calculated using the corrected covered area (CCA). Maps were developed using the location of where primary studies were conducted using DataWrapper App. The protocol was prospectively registered with Open Science Framework registry. Pooled prevalence and incidence rates of PsA or its associated psychological comorbidities in general or specific populations. We also collected locations from the primary studies of the included meta-analyses. Only the assessment of prevalence rates of PsA in people with psoriasis showed slight overlap (CCA = 3.3%). Items 2, 3, 4, 7, 8, 10, 12, and 13 were poorly reported in AMSTAR-2. The pooled prevalence of PsA ranged from 0.13 to 0.15% in the general population, and 15.5% to 19.7% in people with psoriasis. The pooled incidence of PsA ranged from 8.26 to 9.27 cases per 100,000 inhabitants to 0.87 cases in individuals with hidradenitis suppurativa. The pooled prevalence of psychological comorbidities was 11.9-20% for depression, 19-33% anxiety, 38% alexithymia, and 72.9% in poor sleep quality. Only the pooled incidence of depression was assessed with 21.3 per 1000-person year. PsA seems to be prevalent and incident not only in people with psoriasis, but also in general population. Depression and anxiety symptoms may be present in some patients with PsA. Finally, continent disparities exist, and methodological and clinical issues were found, which could be helpful in the future agenda of the epidemiology of PsA.

Multimodal exercise programs may improve posttraumatic stress disorders symptoms and quality of life in adults with PTSD: An overview of systematic reviews with meta-analysis.

OBJECTIVE: This overview of reviews aimed to summarize the effectiveness of exercise, regular physical activity or mind-body exercises on posttraumatic stress disorder (PTSD) symptoms and comorbidities associated with PTSD (e.g. depression symptoms) among individuals without age, gender, race, ethnicity or setting restrictions. DATA SOURCES: The CINAHL, Embase, PubMed and SPORTDiscus databases were searched from inception to November 16, 2023. REVIEW METHODS: Systematic reviews with meta-analysis of randomized clinical trials evaluating exercise, regular physical activity or mind-body exercises were considered. Control groups and outcome measures were not restricted. AMSTAR 2 assessed the methodological quality of reviews. The overlap between reviews was calculated. RESULTS: A total of 14 systematic reviews were included meta-analyzing 23 distinct randomized clinical trials. There was a very high overlap between reviews (corrected covered area = 16%). PTSD symptoms, depression symptoms, anxiety symptoms, sleep quality, substance abuse and quality of life were meta-analyzed. No reviews meta-analyzed the effects of regular physical activity. Overall, the meta-analyses found multicomponent exercise programs may have positive results in reducing PTSD symptoms and improving quality of life. In addition, the results of yoga were inconsistent across the meta-analyses for PTSD symptoms, and no differences between groups were found in favor of yoga for depression symptoms. Finally, no specific conclusions could be made about anxiety symptoms, sleep quality and substance abuse. CONCLUSION: A multicomponent exercise program may be effective in improving PTSD symptoms and quality of life, whereas yoga may be ineffective for depression symptoms in adults with PTSD.

Meaning and purpose in life, happiness, and life satisfaction in cancer: Systematic review with meta-analysis.

OBJECTIVE: To summarize current evidence on the potential cross-sectional and longitudinal association between meaning or purpose in life and subjective happiness or life satisfaction among cancer patients. METHODS: A systematic review with meta-analysis and meta-regression was conducted. CINAHL (via EBSCOhost), Embase, PubMed, and PsycINFO (via ProQuest) were searched from inception to 31 December 2022. In addition, manual searches were performed. The risk of bias in cross-sectional and longitudinal studies was assessed using the Joanna Briggs Institute Checklist for Analytical Cross-Sectional Studies and the Quality in Prognosis Studies tool, respectively. Certainty in the evidence was judged using the Grading of Recommendations, Assessment, Development, and Evaluations approach. Meta-regressions and sensitivity analyses were performed to explore potential sources of heterogeneity. RESULTS: We included 13 cross-sectional studies, comprising 12 different samples, and a longitudinal study. A total of 4968 individuals with cancer were interviewed across included studies. Certainty in the evidence was judged as very low for all outcomes, which was associated to serious concerns on risk of bias and imprecision of the results, and very serious concerns on indirectness of evidence. The assessed studies showed a marked heterogeneity in terms of participants' clinical (i.e., disease stage) and sociodemographic factors. A lack of reporting of these clinical and sociodemographic aspects were also evident among included studies. CONCLUSIONS: The wide number of methodological flaws detected in this systematic review preclude to make any clinical recommendation. More rigorous high-quality observational studies should guide future research on this topic.

Psychological and spiritual interventions to enhance meaning in adults diagnosed with cancer: a systematic review with meta-analysis and meta-regression.

OBJECTIVE: To summarize the evidence on the effectiveness that psychological and/or spiritual interventions may have to change the levels of meaning, measured with the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp), in adults diagnosed with cancer. METHODS: Systematic review with meta-analysis and meta-regression. CINAHL (via EBSCOhost), Embase, PubMed, PsycINFO (via ProQuest), and the Cochrane Library were searched from inception to 21st October 2022. Manual searches were conducted. Only randomized clinical trials (RCTs) were included. The risk of bias was assessed with the Cochrane Risk of Bias tool 2. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to judge the certainty of the evidence. RESULTS: Eight RCTs were included (N = 1682). Although some individual studies showed positive effects to enhance meaning using mindfulness or dignity therapy, the overall and individual meta-analyses showed a lack of effect of psychological and spiritual interventions in comparison to comparator interventions (MD (95%CI) = -0.19 (-0.45 to 0.06), p = 0.11, Tau2 = 0.0015, I2 = 2%). Publication bias was undetected (Egger's test = 0.35). Furthermore, no RCTs were judged to have a low risk of bias and the overall certainty of the evidence was judged as low. Meta-regression and subgroups meta-analyses also found possible sources of heterogeneity such as some cancer characteristics, the educational stage, or the religious affiliation. CONCLUSIONS: Despite some RCTs may show promising results following mindfulness or dignity therapy, no effects were observed in the meta-analysis. Moreover, important methodological and clinical concerns precluded us to make sound clinical recommendations with the available evidence.

No effects were found in favor of Hatha or Iyengar yoga exercises for improving cancer-related fatigue, depression symptoms, or quality of life: a systematic review with meta-analysis and metaregression.

OBJECTIVE: To summarize the evidence on the effectiveness of Hatha or Iyengar yoga exercises on cancer-related fatigue, depression symptoms, and the overall quality of life in adults with cancer. METHODS: A systematic review with meta-analysis was conducted. The CINAHL (via EBSCOhost), Embase, PubMed, and SPORTDiscus (via EBSCOhost) databases were searched from inception to 7th November 2022. Clinical trials evaluating cancer-related fatigue, depression symptoms, and the overall quality of life were included. The risk of bias was assessed using the Cochrane Risk of Bias tool 2. The Template for Intervention Description and Replication (TIDieR) checklist was used to check if the interventions reviewed were described in detail to be implemented in the clinical setting. The Grading of Recommendations, Assessment, Development, and Evaluations approach was used to rate the certainty of evidence. Meta-regressions, sensitivity analyses, and subgroup meta-analyses were conducted to explore sources of heterogeneity. RESULTS: Eleven studies were included (N = 777 participants). Overall, Hatha, Iyengar, and the combination of both yoga styles did not improve any of the outcomes of interest. In addition, five studies had a high risk of bias, and six studies had some concerns about biases. Weaknesses in reporting modifications during the development of the study were observed (TIDieR item 10). The certainty of evidence ranged from low to very low across the outcomes. CONCLUSIONS: We could not make sound clinical recommendations with the current quality of the findings.

Yoga-based interventions may reduce anxiety symptoms in anxiety disorders and depression symptoms in depressive disorders: a systematic review with meta-analysis and meta-regression.

OBJECTIVE: To summarise the effect of mind-body exercises on anxiety and depression symptoms in adults with anxiety or depressive disorders. DESIGN: Systematic review with meta-analysis and meta-regression. DATA SOURCES: Five electronic databases were searched from inception to July 2022. Manual searches were conducted to explore clinical trial protocols, secondary analyses of clinical trials and related systematic reviews. ELIGIBILITY CRITERIA: Randomised clinical trials evaluating qigong, tai chi or yoga styles with anxiety or depression symptoms as the outcomes were included. No intervention, waitlist or active controls were considered as control groups. The risk of bias and the certainty of the evidence were assessed. Meta-analyses, meta-regressions and sensitivity analyses were performed. RESULTS: 23 studies, comprising 22 different samples (n=1420), were included. Overall, meta-analyses showed yoga interventions were superior to controls in reducing anxiety symptoms in anxiety disorders. Furthermore, yoga-based interventions decreased depression symptoms in depressive disorders after conducting sensitivity analyses. No differences between groups were found in the rest of the comparisons. However, the certainty of the evidence was judged as very low for all outcomes due to concerns of high risk of bias, indirectness of the evidence, inconsistency and imprecision of the results. In addition, there was marked heterogeneity among yoga-based interventions and self-reported tools used to evaluate the outcomes of interest. CONCLUSION: Although yoga-based interventions may help to improve mental health in adults diagnosed with anxiety or depressive disorders, methodological improvements are needed to advance the quality of clinical trials in this field.

Dropout Rate of Participants in Randomized Clinical Trials That Use Virtual Reality to Train Balance and Gait in Parkinson's Disease. A Systematic Review With Meta-analysis and Meta-regression.

Virtual reality is an effective system to train balance and gait in Parkinson's disease, but attrition of this intervention needs to be further examined. This study aims to review and meta-analyze the dropouts of participants in randomized clinical trials that used virtual reality for balance and gait training in people with Parkinson's disease. An electronic search was conducted in PubMed, Web of Science, Scopus and CINAHL. The PEDro scale and Revised Cochrane risk-of-bias tool for randomized trials 2.0 were employed to assess methodological quality. Proportions meta-analysis calculated dropout rate. Odds ratio meta-analysis under 1 indicated lower attrition in experimental participants. Meta-regression identified possible dropouts' moderators. A total of 18 studies were included. The pooled dropout rates were 5.6% (95% CI, 3.3%-9.3%) for all groups, 5.33% (95% CI, 3.03%-9.21%) in virtual reality, and 6.60% (95% CI, 3.84%-26.31%) in comparators. No statistical differences were found in the dropout occurred between the groups (OR 0.83; 95% CI, 0.62-1.12). Number of weeks was the unique moderator (coefficient 0.129, 95% CI 0.018- 0.239; p=0.02). Our overall pooled dropout should be considered in the sample size calculation of future studies. Adequate follow-up of the CONSORT guidelines in the loss report and their reasons could help design suitable retention strategies.

Dropout Rate in Digital Health Interventions for the Prevention of Skin Cancer: Systematic Review, Meta-analysis, and Metaregression.

BACKGROUND: Digital strategies are innovative approaches to the prevention of skin cancer, but the attrition following this kind of intervention needs to be analyzed. OBJECTIVE: The aim of this paper is to assess the dropouts from studies focused on digital strategies for the prevention of skin cancer. METHODS: We conducted this systematic review with meta-analyses and metaregression according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statements. Search terms for skin cancer, digital strategies, and prevention were combined to search PubMed, Scopus, Web of Science, CINAHL, and Cochrane Library from inception until July 2022. Randomized clinical trials that reported dropouts of participants and compared digital strategies with other interventions to prevent skin cancer in healthy or disease-free participants were included. Two independent reviewers extracted data for analysis. The Revised Cochrane Collaboration Bias tool was employed. We calculated the pooled dropout rate of participants through a meta-analysis of proportions and examined whether dropout was more or less frequent in digital interventions against comparators via an odds ratio (OR) meta-analysis. Data were pooled using a random-effects model. Subgroup meta-analyses were conducted in a meta-analysis of proportions and OR meta-analysis to assess the dropout events when data were sorted by digital interventions or control comparator. A univariate metaregression based on a random-effects model assessed possible moderators of dropout. Participants' dropout rates as pooled proportions were calculated for all groups combined, and the digital and comparator groups separately. OR>1 indicated higher dropouts for digital-based interventions. Metaregressions were performed for age, sex, length of intervention, and sample size. RESULTS: A total of 17 studies were included. The overall pooled dropout rate was 9.5% (95% CI 5.0-17.5). The subgroup meta-analysis of proportions revealed a dropout rate of 11.6% for digital strategies (95% CI 6.8-19.0) and 10.0% for comparators (95% CI 5.5-17.7). A trend of higher dropout rates for digital strategies was observed in the overall (OR 1.16, 95% CI 0.98-1.36) and subgroup OR meta-analysis, but no significant differences were found between the groups. None of the covariates moderated the effect size in the univariate metaregression. CONCLUSIONS: Digital strategies had a higher dropout rate compared to other prevention interventions, but the difference was not significant. Standardization is needed regarding reporting the number of and reasons for dropouts.

Dropout rate in randomised controlled trials of balance and gait rehabilitation in multiple sclerosis: is it expected to be different for virtual reality-based interventions? A systematic review with meta-analysis and meta-regression.

To assess and meta-analyse the pooled dropout rate from the randomised control trilas that use virtual reality for balance or gait rehabilitation in people with multiple sclerosis. A systematic review of randomised control trials with meta-analysis and meta-regressions was performed. A search was conducted in PubMed, Scopus, Web of Science, the Physiotherapy Evidence Database, the Cochrane Database, CINHAL, LILACS, ScienceDirect, and ProQuest. It was last updated in July 2022. After the selection of studies, a quality appraisal was carried out using the PEDro Scale and the Revised Cochrane risk-of-bias tool for randomised trials. A descriptive analysis of main characteristics and dropout information was performed. An overall proportion meta-analysis calculated the pooled dropout rate. Odds ratio meta-analysis compared the dropout likelihood between interventions. The meta-regression evaluated the influence of moderators related to dropout. Sixteen studies with 656 participants were included. The overall pooled dropout rate was 6.6% and 5.7% for virtual reality and 9.7% in control groups. The odds ratio (0.89, p = 0.46) indicated no differences in the probability of dropouts between the interventions. The number, duration, frequency, and weeks of sessions, intervention, sex, multiple sclerosis phenotype, Expanded Disability Status Scale score, and PEDro score were not moderators (p > 0.05). Adverse events were not reported and could not be analysed as moderators. Dropouts across the virtual reality and control comparators were similar without significant differences. Nonetheless, there is a slight trend that could favour virtual reality. Standardisation in reporting dropouts and adverse events is recommended for future trials.

Metabolic fate of ellagitannins: implications for health, and research perspectives for innovative functional foods.

Consumption of dietary ellagitannins (ETs) has been associated with different health benefits. Nonetheless, ETs are not bioavailable as such and are metabolized in vivo. They are partially converted into ellagic acid (EA) in the upper gastrointestinal (GI) tract, but this first metabolite is also poorly bioavailable. In the lower GI tract, EA and residual ETs are metabolized by gut microbiota to produce urolithins, which, together with their conjugate relatives, persist at relatively high concentrations in plasma and urine for days after ingestion of dietary ETs. Thus, ETs and EA may exert local health benefits on the GI tract but systemic health benefits are more likely to result from urolithins. Cellular models suggest that, at physiological concentration, urolithins are active against chronic degenerative diseases. Health benefits have been proven in animal models and during clinical studies. Even so, the crucial involvement of gut microbiota in ET bioconversion induces important variability of physiological response among humans, giving rise to the concept of high and low urolithin producers. This variability among consumers in obtaining potential health benefits from dietary ETs raises new challenges for the functional food industry. Different research perspectives are discussed to tackle this significant issue for nutritionists, food technologists, and consumers.

Understanding the certainty of evidence from systematic reviews in rehabilitation science: what do clinicians need to know about GRADE?

PURPOSE: Systematic reviews of interventions are published each year evaluating rehabilitation approaches such as exercise, manual therapy, or electrotherapy. Currently, important methodological approaches are available to make systematic reviews more robust and transparent. One of these approaches is the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) system. MATERIAL AND METHODS: A perspective for rehabilitation was conducted aiming to (1) shed light on the meaning and relevance of the GRADE system in systematic reviews with meta-analysis of rehabilitation science, and (2) propose suggestions for helping clinicians improve the interpretation of the GRADE findings. RESULTS: The meaning and relevance of GRADE in rehabilitation science was discussed. Suggestions were proposed to help clinicians in the interpretation of the GRADE findings. We discussed the use of meta-analyses, meta-regressions, subgroups meta-analyses, and sensitivity analyses to increase the objectivity of the domains of GRADE. Finally, a future agenda was provided. CONCLUSION: The use of GRADE is essential for improving the synthesis of evidence that clinicians may often use in rehabilitation practice. However, GRADE is only one hallmark when the findings of systematic reviews are interpreted. The issues of sample size, futile research, pre-registration, switching outcomes, or narrative bias should be also considered.

Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) is helpful in systematic reviews for understanding the certainty of evidence is analyzed.GRADE could detect limitation in the certainty of evidence helping clinicians to choose the best therapeutic option for their patients.Some domains of GRADE (indirectness and inconsistency) are particularly useful for clinicians who aim to translate the conclusions of a synthesis of evidence into clinical practice.

Acceptance and Commitment Therapy for Chronic Pain: An Overview of Systematic Reviews with Meta-Analysis of Randomized Clinical Trials.

This overview of reviews aimed to summarize the evidence from systematic reviews and meta-analyses of randomized clinical trials of the efficacy of acceptance and commitment therapy (ACT) for adults with chronic pain in relation to pain intensity, pain-related functioning, quality of life, and psychological factors. The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, PsycINFO, PubMed, and the Cochrane Library databases were searched from inception to July 2, 2023. AMSTAR 2 was used to assess the methodological quality of systematic reviews. The overlap among reviews was calculated. Nine reviews comprising 84 meta-analyses of interest were included. At post-treatment, some meta-analyses mainly showed that ACT can reduce depression symptoms, anxiety symptoms, psychological inflexibility, and pain catastrophizing; and can improve mindfulness, pain acceptance, and psychological flexibility. At three-month follow-up, ACT can reduce depression symptoms and psychological inflexibility, as well as improve pain-related functioning and psychological flexibility. At six-month follow-up, ACT can improve mindfulness, pain-related functioning, pain acceptance, psychological flexibility, and quality of life. At six-twelve-month follow-up, ACT can reduce pain catastrophizing and can improve pain-related functioning. Some methodological and clinical issues are identified in the reviews, such as a very high overlap between systematic reviews, the fact that the certainty of the evidence is often not rated and specific details needed to replicate the interventions reviewed are often not reported. Overall, however, randomized clinical trials and systematic reviews show that ACT can improve outcomes related to chronic pain (eg, pain-related functioning). Future systematic reviews should address the methodological and clinical concerns identified here to produce higher-quality findings. PERSPECTIVE: Despite certain methodological and clinical issues, randomized clinical trials and systematic reviews of ACT appear to show that it can improve outcomes related to chronic pain (eg, psychological factors).

Spiritual well-being, faith, meaning in life, peace, and purpose in life for cancer-related fatigue: systematic review with meta-analysis and meta-regressions.

BACKGROUND: Cancer-related fatigue is associated with spiritual distress. Spiritual well-being, characterized by the presence of factors such as meaning in life or purpose in life, seems to play an important role in the management of symptoms of cancer. Currently, the number of studies evaluating the association between cancer-related fatigue and spiritual well-being is increasing and no systematic review has been conducted. AIM: To summarize the association between cancer-related fatigue and spiritual well-being, faith, meaning in life, peace, and purpose in life. DESIGN: A systematic review with meta-analysis. DATA SOURCES: The CINAHL, Embase, PsycINFO, and PubMed databases were searched from inception to 9 October 2023. We considered studies evaluating the cross-sectional or longitudinal association between cancer-related fatigue and the spiritual factors above mentioned. The Joanna Briggs Institute Checklist for Analytical Cross-Sectional Studies and the Quality in Prognosis Studies tool assessed the methodological quality of cross-sectional and longitudinal studies, respectively. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system rated the certainty of evidence. Meta-analyses, meta-regressions, subgroup meta-analyses, and sensitivity analyses were conducted. RESULTS: A total of 13 studies were included and no longitudinal findings were found. One meta-analysis showed that cancer-related fatigue may be negatively correlated with spiritual well-being (r = - 0.37 (95%CI - 0.44 to - 0.28) p < 0.01). In addition, another meta-analysis found the correlation between cancer-related fatigue and faith was not statistically significant (r = - 0.25 (95%CI - 0.66 to 0.28) p = 0.36). CONCLUSIONS: Cancer-related fatigue may be correlated with spiritual well-being. However, the certainty of evidence was very low across the meta-analyzed outcomes. IMPLICATIONS FOR CANCER SURVIVORS: A negative correlation was observed between spiritual well-being and cancer-related fatigue.

The prevalence of anxiety and depression in cancer around the world: An overview of systematic reviews evaluating 128 meta-analyses.

BACKGROUND: This overview of systematic reviews with meta-analysis summarized the prevalence of anxiety and depression in different types of tumors around the world. METHODS: The quality of reviews was assessed. The degree of overlap between reviews was calculated. The regional prevalence of anxiety and depression was shown in the main text based on the World Health Organization regions. RESULTS: Twenty-five reviews including 128 meta-analyses of interest were selected. The pooled prevalence of anxiety in breast tumors was in Africa (19 %), the Americas (38 %), Eastern Mediterranean (56 %), Europe (38 %), South-East Asia (42 %), and Western Pacific (26 %). The pooled prevalence of depression in breast tumors was in Africa (40 %), the Americas (23-25 %), Eastern Mediterranean (49-51 %), Europe (27-29 %), South-East Asia (23-33 %), Western Pacific (29 %). The pooled prevalence of depression in digestive tumors was in the Americas (4-44 %), Eastern Mediterranean (42 %), Europe (20-27 %), South-East Asia (66 %), and Western Pacific (24-40 %). The pooled national prevalence of anxiety and depression was mainly evaluated in China and Iran. LIMITATIONS: Important methodological issues were identified. For example, no reviews judged the certainty of evidence. CONCLUSIONS: The Eastern Mediterranean region showed the highest prevalence of anxiety and depression for breast tumors. The South-East Asian region showed the highest prevalence of depression for digestive tumors. In these regions, many countries are considered low-income and middle-income countries. Further research funding would help increase the investigation on this topic, which may allow the development of preventive strategies that reduce the prevalence of anxiety and depression.

Exercise or mind-body exercises for psychiatry symptoms and quality of life in schizophrenia spectrum and other psychotic disorders: an overview of systematic reviews with meta-analysis.

PURPOSE: This overview of systematic reviews with meta-analysis aimed to summarize the effects of exercise, regular physical activity, and mind-body exercises on negative symptoms, depression symptoms, and quality of life in schizophrenia spectrum and other psychotic disorders. MATERIAL AND METHODS: The CINAHL, Embase, PubMed, SPORTDiscus, and the Cochrane Library databases were searched up to November 10, 2023. AMSTAR 2 was used and the overlap between reviews was calculated. RESULTS: Eighteen reviews were included. No reviews meta-analyzed regular physical activity. Aerobic exercise may be more effective than yoga, treatment-as-usual, or multiple controls for reducing negative symptoms. Tai chi may be more effective than multiple controls for decreasing negative symptoms. Aerobic exercise or multimodal exercise programs may be more effective than multiple controls for reducing depression symptoms. Yoga may be more effective than waitlist for decreasing depression symptoms. Aerobic exercise may be more effective than multiple controls for improving quality of life. Yoga may be more effective than treatment-as-usual for improving quality of life. The rest of the meta-analyses found no differences between groups or combined different types of interventions in their meta-analyses. CONCLUSIONS: Despite these results, important methodological concerns were detected that precluded us from making sound clinical recommendations.

Exercise and mind-body exercise for feeding and eating disorders: a systematic review with meta-analysis and meta-regressions.

PURPOSE: To develop a systematic review with meta-analysis to summarize the effectiveness of exercise, regular physical activity, and mind-body exercise on harmful exercise habits, psychological factors, and quality of life in people clinically diagnosed with feeding and eating disorders. MATERIAL AND METHODS: Randomized clinical trials and pilot randomized clinical trials were considered. RESULTS: Twelve studies were included. No studies evaluated athletes. No studies examined regular physical activity as the targeted intervention. Quality of life could not be meta-analyzed. Overall, meta-analyses showed that exercise or mind-body exercise was not more effective than controls in reducing depression symptoms, harmful exercise habits, eating behaviors, or emotional regulation skills. However, important methodological and clinical issues were detected in the included studies. This affected the certainty of evidence of the meta-analyzed outcomes which ranged from low to very low. No studies reported in sufficient detail their interventions to be replicated. CONCLUSIONS: Overall, exercise and mind-body exercise may be ineffective in improving meta-analyzed outcomes. However, the certainty of evidence ranged from low to very low and the body of knowledge in this field needs to be increased to reach robust conclusions.

Exercise and mind-boy exercises were not more effective than controls for eating behaviors in eating disorders.Exercise and mind-boy exercises were not more effective than controls for depression symptoms in eating disorders.Clinicians should be aware no specific exercises can be recommended for treating psychological factors in eating disorders.

How can clinicians enhance self-efficacy beliefs in osteoarthritis? An overview of systematic reviews with meta-analysis.

This overview of reviews aimed to synthesize the effectiveness of non-pharmacological approaches to enhance self-efficacy in people with osteoarthritis. The CINAHL, Embase, PsycINFO, PubMed, SPORTDiscus, and the Cochrane Library databases were searched from inception to December 2023. We considered systematic reviews with meta-analysis of randomized clinical trials evaluating any non-pharmacological intervention. We used AMSTAR 2 to assess the methodological quality of reviews. The overlap between reviews was calculated. We included eight systematic reviews with meta-analysis evaluating 30 different clinical trials. Overall, mind-body exercises, psychological interventions, and self-management strategies may improve arthritis self-efficacy. Specifically, the meta-analyses showed tai chi exercises, coping skills training, and the arthritis self-management program are more effective than controls to enhance arthritis self-efficacy in people with hip and/or knee osteoarthritis. In addition, inconsistent results were detected across meta-analyses regarding the effectiveness of multidisciplinary interventions. Finally, the degree of overlap between all reviews was moderate (CCA = 6%) and many included reviews reported most of the items of AMSTAR 2. Tai chi exercises, coping skills training, and the arthritis self-management program may be beneficial for enhancing arthritis self-efficacy.
