Abstract
The brain controls the nerve system, allowing complex emotional and cognitive activities. The microbiota-gut-brain axis is a bidirectional neural, hormonal, and immune signaling pathway that could link the gastrointestinal tract to the brain. Over the past few decades, gut microbiota has been demonstrated to be an essential component of the gastrointestinal tract that plays a crucial role in regulating most functions of various body organs. The effects of the microbiota on the brain occur through the production of neurotransmitters, hormones, and metabolites, regulation of host-produced metabolites, or through the synthesis of metabolites by the microbiota themselves. This affects the host's behavior, mood, attention state, and the brain's food reward system. Meanwhile, there is an intimate association between the gut microbiota and exercise. Exercise can change gut microbiota numerically and qualitatively, which may be partially responsible for the widespread benefits of regular physical activity on human health. Functional magnetic resonance imaging (fMRI) is a non-invasive method to show areas of brain activity enabling the delineation of specific brain regions involved in neurocognitive disorders. Through combining exercise tasks and fMRI techniques, researchers can observe the effects of exercise on higher brain functions. However, exercise's effects on brain health via gut microbiota have been little studied. This article reviews and highlights the connections between these three interactions, which will help us to further understand the positive effects of exercise on brain health and provide new strategies and approaches for the prevention and treatment of brain diseases.

Community-based group rehabilitation program for stroke patients with dysphagia on quality of life, depression symptoms, and swallowing function: a randomized controlled trial. BMC Geriatr 2023; 23:876. [PMID: 38124046 PMCID: PMC10731687 DOI: 10.1186/s12877-023-04555-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 12/01/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Community-based exercise programs have demonstrated potential for implementation in older adults; however, it remains imperative to ascertain whether this strategy will yield comparable benefit in stroke patients with dysphagia. METHODS This was a single blinded, randomized, matched pairs clinical trial. Sixty-four stroke patients with dysphagia were recruited from patients who had been discharged the Rehabilitation Department of the Third Affiliated Hospital of Sun Yat-sen University. A single blinded, randomized and controlled trial was conducted. Participants were randomly assigned to either the intervention group (n = 32) or the control group (n = 32). Patients in the intervention group received health education followed by swallowing function training in community public spaces for 5 days every week over an eight-week period (60 minutes per day). Patients in the control group received swallowing rehabilitation training, and booster educational information about dysphagia, as well as instructions on how to improve quality of life. Swallowing function (Functional Oral Intake Scale (FOIS) and Standardized Swallowing Assessment (SSA)), depressive symptoms (Geriatric Depression Scale-15), and quality of life (Swallowing-Quality of Life, SWAL-QOL) were assessed before and after all the treatment. RESULTS Before treatment, the two groups did not differ statistically. After the intervention, the swallowing function (SSA and FOIS) showed a significant improvement in both groups (All p < 0.001). But there was no significant difference in Functional Oral Intake Scale change between groups (P = 0.479). Compared with the control group, the intervention group had a significant improvement in depressive symptoms (P = 0.002), with a greater reduction in the number of depressed patients (13 to 6).The control group showed no significant improvements in depressive symptoms or a reduction in the number of depressed patients before and after treatment (P = 0.265, 14 to 12). The Swallowing-Quality of Life scores showed significant improvement in both the intervention and control group (P < 0.001). Specifically within Swallowing-Quality of Life sub-domains, greater changes were observed in symptoms and frequency (P < 0.001), communication (P = 0.012), and sleep (P = 0.006) for participants in the intervention group. And the cost-effectiveness of group rehabilitation surpasses that of rehabilitation training. CONCLUSION Community-based group rehabilitation program is more effective than traditional treatment in improving patients' depressive symptoms and quality of life, as well as being more cost-effective.

Abstract
OBJECTIVE Exercise helps enhance cognitive function in Alzheimer's patients, although the most effective forms of exercise remain unknown. METHODS This network meta-analysis was registered in INPLASY (INPLASY202330066). According to predetermined criteria, this investigation comprised randomized controlled studies involving exercise therapies in people with Alzheimer's disease. The exercise intervention was ranked using surface under the cumulative ranking curve (SUCRA) and mean ranking, with the critical goal outcomes being overall cognition, executive function, and memory function. RESULTS Resistance exercise is the most likely strategy to be beneficial for slowing down overall cognitive function loss in Alzheimer's patients (72.4%). Additionally, multi-component exercise was the most effective way to improve executive function (30.4%). The only type of exercise that significantly affects memory function is resistance exercise. Memory is the cognitive function that is least responsive to exercise. CONCLUSION Resistance exercise may be an efficient intervention for overall cognitive function decline in patients with Alzheimer's and conjointly for their memory function. Multi-component exercise is more effective in improving executive function in patients with Alzheimer's disease.

Comparative efficacy of various exercise interventions on depression in older adults with mild cognitive impairment: A systematic review and network meta-analysis. Ageing Res Rev 2023; 91:102071. [PMID: 37704052 DOI: 10.1016/j.arr.2023.102071] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Revised: 09/06/2023] [Accepted: 09/09/2023] [Indexed: 09/15/2023]
Abstract
BACKGROUND Exercise is a promising nonpharmacological treatment for improving depression in older adults with MCI, but it is unclear which exercises are most effective. The objectives of this study were to compare and rank the effectiveness of various exercise interventions for depression in mild cognitive impairment (MCI) and to investigate the effects of exercise on depression. METHODS The PRISMA-NMA guidelines were applied to the development and reporting of review criteria. The Cochrane Library, Web of Science, PsycINFO, PubMed, EMBASE, CINAHL, and Scopus databases were systematically searched by combining search terms for randomized controlled trial studies (RCTs) published in English from individual databases with the earliest available date set to March 10, 2023. Two evaluators independently selected and evaluated eligible studies of changes in depression in older adults with MCI after an exercise intervention. A protocol for this systematic review was registered in PROSPERO (Registration number: CRD42022377052). RESULTS A network meta-analysis was conducted on 15 eligible RCTs consisting of 4271 subjects, including aerobic (n = 6), mind-body (n = 6) and multicomponent (n = 3) exercise trials. Compared to controls, mind-body exercise showed the strongest improvement in depressive symptoms (SMD = -0.63, 95% CI: -1.13, -0.14), followed by aerobic (SMD = -0.57, 95% CI: -0.88, -0.26) and multicomponent exercise (SMD = -0.53, 95% CI: -1.02, -0.03). Notably, there were no statistically significant differences between exercise types: aerobic vs. mind-body (SMD = 0.06, 95% PrI: -0.71, 0.84), multicomponent vs. mind-body (SMD = 0.11, 95% PrI: -0.75, 0.97), or multicomponent vs. aerobic (SMD = 0.04, 95% PrI: -0.771, 0.86). CONCLUSIONS In this review, we found that mind-body exercise was most effective when compared to conventional controls and that multiple exercise modalities (aerobic, mind-body, and multicomponent exercise) had beneficial and comparable effects in reducing depressive states in older adults with MCI. These findings may guide clinical geriatric stakeholders and allied health professionals in providing more scientifically optimal exercise prescriptions for older adults with MCI. In the future, more high-quality, long-term clinical trials are needed to support the exploration of longer-term dynamic effects.

Abstract
BACKGROUND There is a significant research gap in the field of universal, selective, and indicated prevention interventions for mental health promotion and the prevention of mental disorders. Barriers to closing the research gap include scarcity of skilled human resources, large inequities in resource distribution and utilization, and stigma. OBJECTIVES To assess the effectiveness of delivery by primary workers of interventions for the promotion of mental health and universal prevention, and for the selective and indicated prevention of mental disorders or symptoms of mental illness in low- and middle-income countries (LMICs). To examine the impact of intervention delivery by primary workers on resource use and costs. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, Global Index Medicus, PsycInfo, WHO ICTRP, and ClinicalTrials.gov from inception to 29 November 2021. SELECTION CRITERIA Randomized controlled trials (RCTs) of primary-level and/or community health worker interventions for promoting mental health and/or preventing mental disorders versus any control conditions in adults and children in LMICs. DATA COLLECTION AND ANALYSIS Standardized mean differences (SMD) or mean differences (MD) were used for continuous outcomes, and risk ratios (RR) for dichotomous data, using a random-effects model. We analyzed data at 0 to 1, 1 to 6, and 7 to 24 months post-intervention. For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥ 0.80 large clinical effects. We evaluated the risk of bias (RoB) using Cochrane RoB2. MAIN RESULTS Description of studies We identified 113 studies with 32,992 participants (97 RCTs, 19,570 participants in meta-analyses) for inclusion. Nineteen RCTs were conducted in low-income countries, 27 in low-middle-income countries, 2 in middle-income countries, 58 in upper-middle-income countries and 7 in mixed settings. Eighty-three RCTs included adults and 30 RCTs included children. Cadres of primary-level workers employed primary care health workers (38 studies), community workers (71 studies), both (2 studies), and not reported (2 studies). Interventions were universal prevention/promotion in 22 studies, selective in 36, and indicated prevention in 55 RCTs. Risk of bias The most common concerns over risk of bias were performance bias, attrition bias, and reporting bias. Intervention effects 'Probably', 'may', or 'uncertain' indicates 'moderate-', 'low-', or 'very low-'certainty evidence. *Certainty of the evidence (using GRADE) was assessed at 0 to 1 month post-intervention as specified in the review protocol. In the abstract, we did not report results for outcomes for which evidence was missing or very uncertain. Adults Promotion/universal prevention, compared to usual care: - probably slightly reduced anxiety symptoms (MD -0.14, 95% confidence interval (CI) -0.27 to -0.01; 1 trial, 158 participants) - may slightly reduce distress/PTSD symptoms (SMD -0.24, 95% CI -0.41 to -0.08; 4 trials, 722 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD -0.69, 95% CI -1.08 to -0.30; 4 trials, 223 participants) Indicated prevention, compared to usual care: - may reduce adverse events (1 trial, 547 participants) - probably slightly reduced functional impairment (SMD -0.12, 95% CI -0.39 to -0.15; 4 trials, 663 participants) Children Promotion/universal prevention, compared to usual care: - may improve the quality of life (SMD -0.25, 95% CI -0.39 to -0.11; 2 trials, 803 participants) - may reduce adverse events (1 trial, 694 participants) - may slightly reduce depressive symptoms (MD -3.04, 95% CI -6 to -0.08; 1 trial, 160 participants) - may slightly reduce anxiety symptoms (MD -2.27, 95% CI -3.13 to -1.41; 1 trial, 183 participants) Selective prevention, compared to usual care: - probably slightly reduced depressive symptoms (SMD 0, 95% CI -0.16 to -0.15; 2 trials, 638 participants) - may slightly reduce anxiety symptoms (MD 4.50, 95% CI -12.05 to 21.05; 1 trial, 28 participants) - probably slightly reduced distress/PTSD symptoms (MD -2.14, 95% CI -3.77 to -0.51; 1 trial, 159 participants) Indicated prevention, compared to usual care: - decreased slightly functional impairment (SMD -0.29, 95% CI -0.47 to -0.10; 2 trials, 448 participants) - decreased slightly depressive symptoms (SMD -0.18, 95% CI -0.32 to -0.04; 4 trials, 771 participants) - may slightly reduce distress/PTSD symptoms (SMD 0.24, 95% CI -1.28 to 1.76; 2 trials, 448 participants). AUTHORS' CONCLUSIONS The evidence indicated that prevention interventions delivered through primary workers - a form of task-shifting - may improve mental health outcomes. Certainty in the evidence was influenced by the risk of bias and by substantial levels of heterogeneity. A supportive network of infrastructure and research would enhance and reinforce this delivery modality across LMICs.

Abstract
Breathing control exercises are an important component of occupational therapy in patients with chronic obstructive pulmonary disease (COPD). Delivering these exercises in group settings may enhance their benefits. Therefore, this study assessed the effectiveness of breathing control exercises delivered in a group format to patients with severe COPD remitting from an acute pulmonary exacerbation. This randomized controlled trial of 6 weeks’ duration compared the addition of breathing exercise sessions delivered in a group setting to a standard exercise inpatient rehabilitation program (usual care) versus usual care alone. The standard exercise program consisted of endurance and strength training and therapeutic patient education. The intervention group received, in addition to usual care, 20 sessions of 30 min duration of breathing control exercises in a group setting. The primary outcome was quality of life (Saint George’s Respiratory Questionnaire). Secondary outcomes were the COPD assessment test, modified Borg scale, handgrip strength test, and five-time sit-to-stand test. Thirty-seven patients aged 69 ± 7 years were recruited. After the 6-week period, all outcomes significantly improved and exceeded the minimal clinically important difference in the intervention group only. Between-group changes were significant for each outcome. Conclusions: breathing control exercises in a group setting provide clinically relevant benefits in patients with severe COPD who are remitting from an acute pulmonary exacerbation.

Abstract
BACKGROUND We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to identify the integrated effects of exercise therapy on global cognitive function and, depression in older adults with mild cognitive function (MCI) and to determine the optimal exercise methods. METHODS We searched international, and domestic databases from January 1, 2010, to May 31, 2022, and included 22 articles in the meta-analysis (global cognitive function 21 articles; depression 7articles). Meta-analysis of variance and meta-regression were performed with moderator analysis to explore the causes of heterogeneity RESULTS: The mean effects (standardized mean differences) were 0.65 (95% confidence interval [CI]: 0.39-0.91) for global cognitive function and -0.38 (95% CI: -0.63 to -0.12) for depression in older adults with MCI who received exercise therapy, and the effect was statistically significant. CONCLUSION Aerobic and resistance exercises were effective in improving global cognitive function, Whereas multicomponent and neuromotor exercises were not. Aerobic exercise was the most effective at improving cognitive function. Thus, exercise therapy is effective in reducing depression in older adults with MCI. The mean effect of global cognitive function increased with higher exercise frequency.

Abstract
AIM The aim of the present study was to investigate the effects of different exercise combinations on cognitive status, muscle strength of lower extremities, mobility, physical performance, mood and quality of life in older adults with mild cognitive impairment (MCI). METHODS A total of 48 older adults with MCI were randomly assigned to four groups: (1) aerobic plus lower extremity strengthening exercises (AG), (2) dual-task training plus lower extremity strengthening exercises (DG), (3) aerobic exercise, dual-task training and lower extremity strengthening exercises (ADG), (4) solely lower extremity strengthening exercises (CG). Patients' cognitive status, lower extremity muscle strength, balance, mobility, activities-specific balance confidence, functional exercise capacity, physical performance, mood and quality of life were evaluated. RESULTS In all three intervention groups, there was a significant improvement in cognitive status, balance, mobility, activities-specific balance confidence, physical performance, mood and quality of life (p < 0.05). The most remarkable change was observed in the ADG on cognitive status, mobility and physical performance parameters (p < 0.05). In addition, the most significant improvement in balance parameters was recorded both in the DG and ADG (p < 0.05). Besides, the highest increase in functional exercise capacity was detected both in the AG and ADG (p < 0.05). On the other hand, both exercise combinations were superior to the control group in terms of improving mood and quality of life (p < 0.05). CONCLUSION The trial results proved that aerobic exercise and dual-task training is the best combination for improving cognitive status, mobility and physical performance in older adults with MCI.

Abstract
PURPOSE To investigate the effect of physical exercise on body structure & function and activity outcomes in individuals with Mild Cognitive Impairment (MCI). METHODS Six databases were searched from inception until January 2021. Randomized controlled trials (RCTs) comparing physical exercise with a control group were included. RESULTS Fourteen RCTs were included. Three types of physical exercise were identified: aerobic (AE), resistance (RE), and multimodal (ME). Regarding body structure & function outcomes, evidence for RE was very low and with effect for improvement in upper limb muscle strength and very low and without effect for lower limbs. For improvement in postural balance, evidence was very low and with effect with AE and very low and without effect with RE and ME. Evidence for cardiorespiratory function was very low and without effect with AE and RE. Regarding activity outcomes, evidence was low and without effect for mobility with AE and very low and without effect with RE and ME. CONCLUSIONS Physical exercise promoted improvements in body structure & function outcomes in individuals with MCI. Resistance exercise improvement upper limb muscle strength and AE enhanced postural balance. In contrast, physical exercise did not promote a significant benefit in activity outcomes.Implications for rehabilitationResults of this systematic review have shown that physical exercise promoted improvements in body structure & function outcomes in individuals with Mild Cognitive Impairment (MCI).Resistance exercise with elastic bands for approximately 60 minutes twice a week for a total of three months improved upper limb muscle strength.Aerobic exercise with walking for approximately 60 minutes twice per week for a total of six months enhanced postural balance.Considering the potential benefits identified in this systematic review, physical exercise can be recommended for individuals with MCI.We also highlight the importance of the use of the International Classification of Functioning, Disability and Health for rehabilitation planning.

Physical Exercise as a Nonpharmacological Intervention for the Treatment of Neuropsychiatric Symptoms in Persons With Dementia: A Meta-analysis of Randomized Controlled Trials. Alzheimer Dis Assoc Disord 2023; 37:73-81. [PMID: 36821178 DOI: 10.1097/wad.0000000000000544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 12/28/2022] [Indexed: 02/24/2023]
Abstract
BACKGROUND Neuropsychiatric symptoms (NPS) are prevalent in dementia and affect both patients and caregivers in multiple ways. Because of the complications of drug treatments, nonpharmacological interventions, such as exercise, are of particular value. This study aimed to investigate the effect of exercise on the NPS of dementia and draw recommendations for the disease management. METHODS Meta-analyses were conducted on the findings of randomized controlled trials identified during an initial systematic review of the literature, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The included studies examined the effect of exercise interventions on patients with dementia or mild cognitive impairment using valid assessment tools. The quality of evidence was assessed using Grading of Recommendations, Assessment, Development, and Evaluation analysis. RESULTS The meta-analyses revealed that exercise significantly limits NPS [mean difference: -5.28, (95% CI, -9.46, -1.11), P = 0.01] and symptoms of depression [standardized mean difference: -0.16, (95% CI, -0.29, -0.02), P = 0.02], and has a beneficial effect on agitation symptoms. The Grading of Recommendations, Assessment, Development, and Evaluation analysis results showed that exercise has a moderate and high confidence positive effect on NPS and depression, respectively. CONCLUSIONS Exercise could be an alternative approach for nonpharmacological treatment of NPS in dementia. Therefore, exercise could be utilized as a treatment of choice or to support existing treatment regimens.

Abstract
The purpose of this study was to analyze the effect of real-time online Pilates exercise during COVID-19 on women's body composition, blood lipids, and psychological health after childbirth. The participants were 16 pregnant women (24-28 weeks pregnant) enrolled at the C Women's Culture Center in Seoul, South Korea, classified into online Pilates groups and non-exercise groups (PE, n = 8; CON, n = 8). The online Pilates program was conducted for 8 weeks, twice a week, and 50 min a day using a real-time video chat app. Participants visited the hospital twice for body composition and blood tests. Questionnaires on postpartum depression, sleep disorder, and stress were conducted at 6 weeks and 12 weeks after childbirth. We found a significant difference between groups in body composition. The weight, percentage of body fat, body fat mass, and BMI of the PE group decreased. Blood lipids showed significant differences between the groups in TC, TG, LDL and CRP, while insulin and HDL showed no difference. All blood lipids, insulin, and CRP in the PE group were reduced. There were significant differences between the groups in postpartum depression, sleep disorders, and perceived stress indices performed in the post-test, and the serotonin concentration in the PE group increased. Serotonin levels were significantly correlated with postpartum depression, body fat mass, and body fat rate. Pregnant women's online Pilates in this study was effective at reducing weight and depression in women after childbirth and should be used to promote women's mental health during COVID-19.

Abstract
BACKGROUND This study aimed to examine the potential independent association of functional disability with major depression and moderating effects of social support variables including marital status, living arrangement and social participation in such associations. METHODS Data for the study were drawn from the Longitudinal Ageing Study in India (LASI) wave 1 that was collected during 2017-18 including a sample of 31,464 individuals aged 60 years and above. Descriptive statistics and results from bivariate analysis have been reported. Further, moderated multivariable logistic regression models were used to fulfil the study objective. Major depressive disorder was assessed using the scale of the Short Form Composite International Diagnostic Interview (CIDI-SF). RESULTS It was found that 8.67% of older participants were depressed in this study. Older adults who had difficulty in basic activities of daily living (BADL) (15.34%), difficulty in instrumental activities of daily living (IADL) (12.06%), unmarried (10.13%), separate living (9.67%) and socially inactive (10.09) were having higher prevalence of major depression compared to their respective counterparts. The adjusted model-1 revealed that older adults who had difficulty in BADL and IADL were 2.53 times [AOR: 2.53, CI: 2.17-2.95] and 2.27 times [AOR: 2.27, CI: 1.97-2.64] more likely to have major depression than those with no difficulty in BADL and IADL respectively. Further, interaction analyses found that currently unmarried status, separate living and being socially inactive have moderation effects in the observed associations and exacerbate the likelihood of major depression among older adults who are functionally impaired. CONCLUSIONS The findings highlight the importance of integrating social participation in the daily life of older adults and developing initiatives that promote a healthy surrounding such as social connectedness, co-residential living and special care for those who are physically disabled to protect against late-life depression.

Abstract
This study aims to compare the effects of multitask (MTT; multiple tasks performed simultaneously) and multicomponent training (MCT; various types of exercise performed sequentially) on processing speed, cognitive functions, gait speed, and balance functions in persons with mild cognitive impairment. Forty-two persons with mild cognitive impairment were randomly allocated to MTT (n = 21) or MCT (n = 21). Outcome measures included processing speed, cognitive functions (attention and executive functions), single-task gait speed, dual-task gait speed (DTGS-Arithmetic and DTGS-Verbal), and balance functions. Processing speed (except inhibition), cognitive functions, gait speed, and balance functions improved in the MTT and MCT groups following training, with no significant differences between the groups in processing speed or cognitive functions. The MCT group improved more on single-task gait speed (F = 15.097; p = .000; r = .270) and DTGS (DTGS-Arithmetic; F = 10.594; p = .002; r = .214), while the MTT group improved more on balance functions (F = 4.366; p = .043; r = .101). MTT and MCT strategies can be used to improve cognitive and physical outcomes in persons with mild cognitive impairment.

Abstract
BACKGROUND Exercise is a promising nonpharmacological therapy for cognitive dysfunction, but it is unclear which type of exercise is most effective. The objective of this study was to compare and rank the effectiveness of various exercise interventions on cognitive function in patients with mild cognitive impairment (MCI) or dementia and to examine the effects of exercise on the symptoms relevant to cognitive impairment. METHODS We searched PubMed, Web of Science, Embase, Cochrane Central Register of Controlled Trials, SPORTDiscus, and PsycInfo through September 2019 and included randomized controlled trials that examined the effectiveness of exercise interventions in patients with MCI or dementia. Primary outcomes included global cognition, executive cognition, and memory cognition. Secondary outcomes included activities of daily living, neuropsychiatric symptoms, and quality of life. Pairwise analyses and network meta-analyses were performed using a random effects model. RESULTS A total of 73 articles from 71 trials with 5606 participants were included. All types of exercise were effective in increasing or maintaining global cognition, and resistance exercise had the highest probability of being the most effective intervention in slowing the decrease in global cognition (standard mean difference (SMD) = 1.05, 95% confidence interval (95%CI): 0.56-1.54), executive function (SMD = 0.85, 95%CI: 0.21-1.49), and memory function (SMD = 0.32, 95%CI: 0.01-0.63) in patients with cognitive dysfunction. Subgroup analyses for patients with MCI revealed different effects, and multicomponent exercise was most likely to be the optimal exercise therapy for preventing the decline of global cognition (SMD = 0.99, 95%CI: 0.44-1.54) and executive function (SMD = 0.72, 95%CI: 0.06-1.38). However, only resistance exercise showed significant effects on memory function for patients with MCI (SMD = 0.35, 95%CI: 0.01-0.69). Exercise interventions also showed various effects on the secondary outcomes. CONCLUSION Resistance exercise has the highest probability of being the optimal exercise type for slowing cognitive decline in patients with cognitive dysfunction, especially in patients with dementia. Multicomponent exercise tends to be most effective in protecting global cognition and executive function in patients with MCI.

Abstract
BACKGROUND The management of neuropsychiatric symptoms (NPS) in patients with dementia is a major challenge. Since no effective therapy has been found to date and drug treatments are associatedwith significant side effects, there seems to be a pressing need for alternative non-pharmacological interventions. OBJECTIVES The current study aims to investigate and compare the effect of different types of physical exercise on the NPS. METHODS A systematic review of the literature was conducted according to the PRISMA guidelines. Five databases (SCOPUS, PubMed, SPORT Discus, Web of science and ScienceDirect) were searched using the appropriate algorithm. What was sought out was randomized control trials (RCTs) that applied physical activity interventions with specific characteristics (type, frequency, intensity, and duration) in patients with dementia or mild cognitive impairment, studied the effect of exercise on their NPS and compared this effect with a control group that did not follow an exercise program. RESULTS From 512 articles, 13 studies were included in this review, involving a total of 1,925 patients. The results were analyzed and synthesized according to the type of exercise applied - aerobic exercise, multidimensional interventions and muscular strength training programs. In particular, the results showed that repetitive aerobic exercise three to five times a week had a positive effect on NPS, whereas multidimensional interventions combining different types of exercise did not appear to be as effective. Strength training programs have been found to significantly reduce depression symptoms and behavioral problems in demented patients with mobility problems. CONCLUSIONS There is clear evidence that physical activity and especially aerobic exercise may be effective in the management of NPS. However, it is necessary to apply specific practical recommendations and specially designed programs to incorporate physical exercise into the daily routine of these patients.

Abstract
Introduction The COVID-19 pandemic led to the implementation of physical–social distancing measures–including self-isolation, home confinement, and quarantine around the world, with psychological consequences such as depression. Older adults are especially likely to develop depressive symptomatology. This study aims to investigate the association between physical activity intensities and sedentary behavior with depression levels among previously active older adults during the COVID-19 lockdown. Methods A total of 1,123 physically active older Brazilian adults (67.68 ± 5.91 years, 91.00% female) were interviewed by telephone in regard to sociodemographic, general health status, depression (GDS-15), and physical activity (IPAQ-SV) after being home-confined for 11.59 ± 2.42 weeks. Participants were also asked to self-report changes in their physical activity levels and time spent sitting. Descriptive statistics (mean, frequencies), between-groups comparisons (t-tests and chi-square), and hierarchical regression analysis were used. Results About 83.80% of older adults self-reported a decrease in daily physical activity levels and 73.90% increased sitting time. Overall, depressive symptoms were observed in 30.40, and 20.80% met physical activity recommendations. Daily moderate (β = −0.174; 95% CI = −0.026; -0.012) and moderate-to-vigorous (β = −0.183; 95% CI = −0.023; 0.011) physical activity intensities were negatively associated with depression score explaining 2.6 and 2.9% of depression variability, respectively, after adjusting for age, gender, education level, body mass index, and polypharmacy. Daily walking and sitting time were not associated with the depression score (p > 0.05). Conclusion The results provide empiric suggestion supporting moderate to vigorous physical activity as a way to reduce depressive levels among older adults during COVID-19 confinement. Supervised home-based exercise programs, specifically designed for older adults, might be an important strategy to maintain and improve older adults’ mental health.

Abstract
Depressive disorders are common among the elderly. Major depressive disorder will be one of the highest healthcare costs in middle and higher income countries by 2030. It is known that physical inactivity leads to negative effects on mental health in the elderly.The purpose of this review was to explore investigate the consequences of physical exercise (aerobic and resistance exercise) on major depressive disorder among elderly, and presenting its potential biological mechanisms. This study was designed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Clinical trials or randomized clinical trials or cohort studies participated of the study design. Ten studies were evaluated and the main outcomes of each were reported. Aerobic and resistance training revealed to be effective in fighting the symptoms of depression. The most common physical exercise protocol adopted to reduce the consequences of major depressive disorder in humans was the prescription of aerobic exercise at moderate-intensity lasting 60 min per session, 3 times per week, for 24 weeks. Physical exercise enhances IGF-I and activates PGC-1α/FNDC5/Irisin pathway. Physical exercise also increases expression of BDNF and its receptor, TrkB, in the hippocampus and prefrontal cortex leading to upstream of ERK and inhibiting depressive-like behavior. Physical exercise brings mental health benefits and plays a crucial role in avoiding the development of major depressive disorder.

Abstract
Older adults with mild cognitive impairment (MCI) are at an increased risk for falls and fall-related injuries. It is unclear whether current balance rehabilitation techniques largely developed in cognitively intact populations would be successful in older adults with MCI. This mapping review examined the available balance rehabilitation research conducted in older adults with MCI. Databases Medline, Cinahl, Cochrane, PubMed, Scopus, and PsycINFO were systematically searched from inception to August 2020. Twenty-one studies with 16 original randomized controlled trials (RCTs) involving 1201 older adults with MCI (>age 60) met the inclusion criteria, of which 17 studies showed significant treatment effects on balance functions. However, only six studies demonstrated adequate quality (at least single-blind, no significant dropouts, and intervention and control groups are equivalent at baseline) and evidence (medium or large effect size on at least one balance outcome) in improving balance in this population, and none of them are double- or triple-blind. Therefore, more high-quality RCTs are needed to inform future balance rehabilitation program development for older adults with MCI. Moreover, few studies examined the incidence of falls after the intervention, which limits clinical utility. Future RCTs should prospectively monitor falls or changes in risk of falls after the intervention.

Abstract
OBJECTIVES Non-pharmacological treatments are an important aspect of dementia care. A wide range of interventions have been trialled for mild dementia and mild cognitive impairment (MCI). However, the variety of outcome measures used in these trials makes it difficult to make meaningful comparisons. The objective of this study is to map trends in which outcome measures are used in trials of non-pharmacological treatments in MCI and mild dementia. DESIGN Scoping review. DATA SOURCES EMBASE, PsychINFO, Medline and the Cochrane Register of Controlled Trials were searched from inception until February 2018. An additional search was conducted in April 2019 ELIGIBILITY: We included randomised controlled trials (RCTs) testing non-pharmacological interventions for people diagnosed with MCI or mild dementia. Studies were restricted to full RCTs; observational, feasibility and pilot studies were not included. CHARTING METHODS All outcome measures used by included studies were extracted and grouped thematically. Trends in the types of outcome measures used were explored by type of intervention, country and year of publication. RESULTS 91 studies were included in this review. We extracted 358 individual outcome measures, of which 78 (22%) were used more than once. Cognitive measures were the most frequently used, with the Mini-Mental State Examination being the most popular. CONCLUSIONS Our findings highlight an inconsistency in the use of outcome measures. Cognition has been prioritised over other domains, despite previous research highlighting the importance of quality of life and caregiver measures. To ensure a robust evidence base, more research is needed to highlight which outcome measures should be used over others. PROSPERO REGISTRATION NUMBER CRD42018102649.

Abstract
CONTEXT Falls and loss of autonomy are often attributed in large part to musculoskeletal impairments in later adulthood. Age-related declines in flexibility contribute to late adulthood musculoskeletal impairment. The novel sitting-rising test has been proposed to be a quick, effective screening of musculoskeletal fitness, fall risk, and all-cause mortality in older adults. The timed up and go and 5 times sit-to-stand tests are two of the 3 most evidence-supported performance measures to assess fall risk. OBJECTIVE This study aimed to determine if 5 weeks of flexibility training could increase sitting-rising test, timed up and go, and 5 times sit-to-stand scores in community-dwelling older adults. PARTICIPANTS Forty-seven adults aged 60 years and older (mean age = 66.7 y, SD = 4.1) participated in this study. Participants completed a static stretching protocol consisting of 3 weekly 1-hour stretching sessions. RESULTS The protocol improved flexibility as seen in sit-and-reach scores and improved scores on all outcome variables. Specifically, there was a significant increase in sitting-rising test scores from preintervention (M = 7.45, SD = 1.45) to postintervention (M = 8.04, SD = 1.36), t(42) = -5.21, P < .001. Timed up and go scores demonstrated a significant decrease from preintervention (M = 8.85, SD = 1.32) to postintervention (M = 8.20, SD = 1.35), t(46) = 5.10, P < .001. Five times sit-to-stand scores demonstrated a significant decrease from preintervention (M = 12.57, SD = 2.68) to postintervention (M = 10.46, SD = 2.06), t(46) = 6.62, P < .001. Finally, significant increases in sit-and-reach scores were associated with improved functional performance (r = -.308, P = .03). CONCLUSION Findings suggest that flexibility training can be an effective mode of low-level exercise to improve functional outcomes. Static stretching may help to improve musculoskeletal health, promote autonomy, and decrease mortality in community-dwelling older adults.
