Physical Activity and Exergames Among Older Adults: A Scoping Review

Ismail NA, Hashim HA, Ahmad Yusof H

Games Health J, 2022 Feb;11(1):1-17.

Recently, exergames have been widely applied as exercise platforms among older adults. However, studies on the influence of exergames on older adults' physical activity remain scarce. The review article highlights the potential benefit of exergames as a physical activity tool for older adults. The literature search followed the PRISMA guidelines on databases PubMed (Public/Publisher MEDLINE), CINAHL (Cumulative Index to Nursing and Allied Health Literature), Cochrane, and Scopus. The literature included studies that evaluated the influence of exergames on older adults' physical activity. Articles were excluded if the mixed intervention was used, emphasizing specific limbs, improving specific tasks, or not mentioning intervention. The review article identified 25 studies that reported on 855 older adults 55 years of age and older. In addition, the common exergaming technology platforms examined were Microsoft Kinect™, Nintendo® Wii™, cybercycling, and interactive video dance games. Meanwhile, 11 studies used a pretest/post-test design and randomized controlled trial design in 14 studies. The review found that exergames significantly impacted the older adults' physical activity level as participants experienced improved balance and cognitive function, and enjoyed playing exergame, thus prolonging their game engagement. Although research on exergames is still new, current evidence showed a significant potential benefit of exergames as a physical activity tool for older adults. To overcome the limitation on various parameters that showed different effects and outcomes of exergames, the study recommends implementing randomized controlled trials with long-term observation using a mixed-method approach. Moreover, a multidisciplinary method involving exercise and neuromotor control experts could determine potential mechanisms of action that benefited from the exercises.
A narrative review of brain-derived neurotrophic factor (BDNF) on cognitive performance in Alzheimer's disease

Ismail NA, Leong Abdullah MFI, Hami R, Ahmad Yusof H

Growth Factors, 2021 01 11;38(3-4):210-225.

Brain-derived neurotrophic factor (BDNF) is a neurotrophin that is highly expressed in the brain. It influences neuronal survival, growth and acts as a control centre for neurotransmitters. It also plays a crucial role in learning and memory. Current evidence indicates that BDNF may be a possible neurotrophic factor that controls cognitive functions under normal and neuropathological conditions. Recent findings indicate a reduction in cognitive performance in individuals with Alzheimer's disease (AD). This relationship between cognitive performance and AD is important for investigating both the time they overlap and the pathophysiological mechanism in each case. Therefore, this study reviewed the existing knowledge about BDNF and cognitive performance in the AD population. The findings support the idea that this tropic factor may be a potential biomarker for evaluating the changes in cognitive performance in AD.

PMID: 27345820 DOI: 10.1111/asj.12634

Papaya leaf methanolic extract (PLE) at concentrations of 0 (CON), 5 (LLE), 10 (MLE) and 15 (HLE) mg/250 mg dry matter (DM) with 30 mL buffered rumen fluid were incubated for 24 h to identify its effect on in vitro ruminal methanogenesis and ruminal biohydrogenation (BH). Total gas production was not affected (P > 0.05) by addition of PLE compared to the CON at 24 h of incubation. Methane (CH4 ) production (mL/250 mg DM) decreased (P h incubation, which resulted in higher concentrations of BH intermediates such as C18:1 t11 (vaccenic acid; VA), c9t11 conjugated LA (CLA) (rumenic acid; RA) and t10c12 CLA. Real-time PCR analysis indicated that the total bacteria, total protozoa, Butyrivibrio fibrisolvens and methanogen population in HLE decreased (P <0.05) compared to CON, but the total bacteria and B. fibrisolvens population were higher (P
Fulltext Depression and anxiety in the Malaysian urban population and their association with demographic characteristics, quality of life, and the emergence of the COVID-19 pandemic

Leong Bin Abdullah MFI, Ahmad Yusof H, Mohd Shariff N, Hami R, Nisman NF, Law KS

Curr Psychol, 2021;40(12):6259-6270.

The prevalence of depression and anxiety has been shown to be higher in the urban population compared with the rural population. The present study investigated the prevalence of depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms and their associated factors in a random sample drawn from several urban communities in Malaysia. This study also determined the association between the emergence of the COVID-19 pandemic and depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms. We recruited 326 participants, who were administered a sociodemographic characteristics questionnaire; the 21-item Depression, Anxiety, and Stress Scale (DASS-21) to assess the presence or absence of depression symptoms, anxiety symptoms, and depression with comorbid anxiety symptoms; and the World Health Organization Quality of Life-BREF (WHOQoL-BREF) to assess their QoL. The following prevalence values were obtained among the participants: depression symptoms, 23.9%; anxiety symptoms, 41.7%; and depression with comorbid anxiety symptoms, 19.9%. Those assessed after the declaration of COVID-19 as a global pandemic showed increased odds of depressive symptoms (adjusted OR = 2.99, 95% CI = 1.41-6.35, p = 0.006) and depressive with comorbid anxiety symptoms (adjusted OR = 3.19, 95% CI = 1.37-7.45, p = 0.005), while the presence of comorbid stress increased the odds of depressive symptoms (adjusted OR = 16.00, 95% CI = 7.84-32.63, p
Fulltext Study protocol on the efficacy of exergames-acceptance and commitment therapy program for the treatment of major depressive disorder: comparison with acceptance and commitment therapy alone and treatment-as-usual in a multicentre randomised controlled trial

Zhang B, Deng H, Ren J, Legrand FD, Ahmad Yusof H, Zhang R, et al.

BMJ Open, 2024 Jun 26;14(6):e080315.

BACKGROUND: The prevalence of major depressive disorder (MDD) is on the rise globally, and the use of antidepressant medications for its treatment does not usually result in full remission. However, the combination of physical exercise and psychotherapy for the treatment of MDD increase the rate of full remission among patients. This three-armed, parallel-group, double-blinded randomised controlled trial (RCT) aims to assess and compare the effects between the combination of exergame and acceptance and commitment therapy (e-ACT) programme, ACT only and treatment-as-usual (TAU) control groups on the severity of depression and anxiety symptoms, the degree of experiential avoidance and quality of life (QoL) and the serum levels of depression biomarkers (such as brain-derived neurotrophic factor, C-reactive protein and vascular endothelial growth factor) among patients with MDD across three time points.
METHODS AND ANALYSIS: This RCT will recruit 126 patients with MDD who will be randomised using stratified permuted block randomisation into three groups, which are the combined e-ACT programme, ACT-only and TAU control groups in a 1:1:1 allocation ratio. The participants in the e-ACT and ACT-only intervention groups will undergo once a week intervention sessions for 8 weeks. Assessments will be carried out through three time points, such as the pre-intervention assessment (t0), assessment immediately after completion of the intervention at 8 weeks (t1) and assessment at 24 weeks after completion of the intervention (t2). During each assessment, the primary outcome to be assessed includes the severity of depression symptoms, while the secondary outcomes to be assessed are the severity of anxiety symptoms, experiential avoidance, QoL and depression biomarkers.
ETHICS AND DISSEMINATION: Approval of this study was obtained from the Human Research Ethics Committee of Universiti Sains Malaysia (USM/JEPeM/PP/23050420). The findings of the study will be published in academic peer-reviewed journals.
