RESUMEN
OBJECTIVES: Various interventions have sought to break sedentariness among office workers, but their pooled effect on sitting time reduction remains unknown. Also, it is essential to compare the effectiveness of different intervention types. STUDY DESIGN: Systematic review and meta-analysis. METHODS: A literature search was conducted in the PubMed, EMBASE, Scopus, Web of Science, MEDLINE (via EBSCO), PsycINFO, and Cochrane Library databases from inception to May 2, 2023. Two independent reviewers screened eligibility, extracted data, and assessed the risk of bias using the Cochrane risk of bias tool 2.0. Randomized controlled trials aiming to reduce sitting at work were included. The primary outcome was sitting time at work per day. The secondary outcomes included cardiometabolic risk factors, psychological well-being, and work engagement. A random effects model was performed to synthesize continuous data as mean differences with 95% confidence intervals (95% CIs). RESULTS: Twenty-four studies with 3169 participants were included. All intervention types in combination significantly reduced workplace sitting by 38 min per workday (95% CI: -47.32 to -28.72; P < 0.001; I2 = 49.78%). Interventions using environmental support (ES), motivational strategies (MS), or multiple components (multi) had all shown a significant reduction in work-time sedentary behavior (SB) relative to control groups. Regarding secondary outcomes, no significant effects were observed in physical or psychological outcomes besides high-density lipoprotein. CONCLUSIONS: Findings suggest that SB reduction interventions are generally effective for reducing workplace sitting. Multi interventions with both ES and MS are recommended for future clinical applications. Future studies should aim not only to reduce SB but also to attain the benefits of SB reduction interventions on physical and psychological well-being.

Neurogenesis is the process by which functional new neurons are generated from the neural stem cells (NSCs) or neural progenitor cells (NPCs). Increasing lines of evidence show that neurogenesis impairment is involved in different neurological illnesses, including mood disorders, neurogenerative diseases, and central nervous system (CNS) injuries. Since reversing neurogenesis impairment was found to improve neurological outcomes in the pathological conditions, it is speculated that modulating neurogenesis is a potential therapeutic strategy for neurological diseases. Among different modulators of neurogenesis, melatonin is a particularly interesting one. In traditional understanding, melatonin controls the circadian rhythm and sleep-wake cycle, although it is not directly involved in the proliferation and survival of neurons. In the last decade, it was reported that melatonin plays an important role in the regulation of neurogenesis, and thus it may be a potential treatment for neurogenesis-related disorders. The present review aims to summarize and discuss the recent findings regarding the protective effects of melatonin on the neurogenesis impairment in different neurological conditions. We also address the molecular mechanisms involved in the actions of melatonin in neurogenesis modulation.

AIMS AND OBJECTIVES: This study evaluates the clinical effectiveness of a multicomponent aroma-massage with an acupressure treatment protocol and compared it to cognitive training for the management of behavioural and psychological symptoms of dementia. BACKGROUND: Pharmacological interventions have been unsatisfactory in managing behavioural and psychological symptoms of dementia; thus, complementary and alternative medicine has been extensively researched to identify an adjunct safe and cost-effective intervention. DESIGN: This randomised clinical trial utilised a three-arm parallel group design. Cognitive training was used as a conventional intervention to manage behavioural and psychological symptoms of dementia, whereas exercise was considered "treatment as usual" in this study; both were used as comparisons with the experimental protocol. There were three treatment groups: Group 1: aroma-massage with acupressure + exercise, Group 2: cognitive training + exercise and Group 3: aroma-massage with acupressure + cognitive training. METHOD: Sixty older adults were recruited and randomly assigned to the three groups (20 each). Using the 29-item Chinese Version of the Cohen-Mansfield Agitation Inventory, Neuropsychiatric Inventory, Mini-mental State Examination and Barthel Index-20, the outcome measures were assessed at preintervention, postintervention and the 3-month follow-up to assess behaviour, Activities of Daily Living, cognition, and behavioural and psychological symptoms of dementia severity and distress. Multiple comparisons performed through repeated measures were analysed to detect between-group differences and within-subject differences, as well as the interaction effects between groups and times. RESULTS: The Group 1 and 3 participants showed a significant reduction in the severity and distress caused by behavioural and psychological symptoms of dementia, whereas Group 2 did not demonstrate similar effects. CONCLUSIONS: This clinical study suggests that aroma-massage with acupressure is as effective as cognitive training and can enhance cognitive training in reducing the severity and distress of behavioural and psychological symptoms of dementia. RELEVANCE TO CLINICAL PRACTICE: Aroma-massage with acupressure may serve as an adjunct therapy to reduce behavioural and psychological symptoms of dementia. This therapy is safe, cost-effective and can be implemented by caregivers and family members who are not professionally trained.

OBJECTIVE: In this randomized controlled trial, we investigated the effectiveness of integrated supported employment (ISE) compared with individual placement and support (IPS) and traditional vocational rehabilitation (TVR) for people with schizophrenia in mainland China. METHOD: One hundred and sixty-two participants with schizophrenia were randomly assigned to ISE (n = 54), IPS (n = 54), or TVR (n = 54). Blinded assessments of employment status, job tenure, and psychological outcomes were conducted at admission; completion of the 3-mo program; and follow-up at 7, 11, and 15 mo. RESULTS: Significantly higher employment rate and longer job tenure were found in the ISE group (63.0%, 29.56 wk) compared with the IPS group (50.0%, 25.47 wk) and TVR group (33.3%, 9.91 wk). The ISE group also attained the most positive psychological outcomes. CONCLUSION: Work-related social skills training embedded in ISE with generalization strategies can enhance vocational and nonvocational outcomes for people with schizophrenia in mainland China.

Pain interferes with one's work and social life and, at a personal level, daily activities, mood, and sleep quality. However, little research has been conducted on pain interference and its socioecological determinants among the working poor. Noting the clinical/policy decision needs and the technical challenges of isolating the intricately interrelated socioecological factors' unique contributions to pain interference and quantifying the relative contributions of each factor in an interpretable manner to inform clinical and policy decision-making, we deployed a novel random forest algorithm to model and quantify the unique contribution of a diverse ensemble of environmental, sociodemographic, and clinical factors to pain interference. Our analyses revealed that features representing the internal built environment of the working poor, such as the size of the living space, air quality, access to light, architectural design conducive to social connection, and age of the building, were assigned greater statistical importance than other more commonly examined predisposing factors for pain interference, such as age, occupation, the severity and locations of pain, BMI, serum blood sugar, and blood pressure. The findings were discussed in the context of their benefit in informing community pain screening to target residential areas whose built environment contributed most to pain interference and informing the design of intervention programs to minimize pain interference among those who suffered from chronic pain and showed specific characteristics. The findings support the call for good architecture to provide the spirit and value of buildings in city development.

Background: Individuals with major depressive disorder have a cognitive bias toward emotional stimuli, which influences the quality and speed of emotional information processing. This study aimed to understand the factors underlying this bias by identifying when it occurs during information processing using an information processing model. Methods: A total of 57 participants-19 each [ (16 (84.21%) females and 3 (15.79%) males per group)], for the first-episode MDD (FMDD), recurrent episodes MDD (RMDD), and healthy controls (HCs) - matched for sex and hand preference, completed event-related potentials (ERP) to perform psychological function and a choice response time task. Results: Results revealed that recurrent episodes major depressive disorder participants had decreased N2b and P3b amplitudes but increased contingent negative variation during the processing of happy and neutral facial stimuli, relative to their counterparts. Both recurrent episodes major depressive disorder and first-episode major depressive disorder participants used a parallel information processing strategy for happy information at P3a latency, while healthy controls used a linear information processing strategy. Conclusion: The use of a parallel processing strategy among individuals with major depressive disorder may have led to impaired "happy" information processes, possibly explaining why individuals with major depressive disorder are less efficient than healthy controls. The results suggest the possibility that biases related to the processing of "happy" information among individuals with major depressive disorder may be related to a tendency for these individuals to engage in superficial decision-making. Future research is needed to examine the processes contributing to people with major depressive disorder having challenges with inhibition-facilitation of emotional stimuli.
RESUMEN
This study explored the impacts of five types of community support services (i.e., center-based care, home-based care, respite care, caregiver assistance, and financial subsidies) on self-efficacy for continuous community living among individuals with disabilities and caregivers. DESIGN: Cross-sectional. METHOD: The sample consisted of a group of individuals with disabilities (n = 948) and a group of caregivers (n = 522). A mixed ANOVA was applied to explore the differences in the perceived importance of improvements to community support services between the groups. Logistic regression analyses were conducted to examine the perceived importance of improvements to types of community support services for self-efficacy for continuous community living. RESULTS: Caregivers perceived higher levels of importance for improvements to community support services than individuals with disabilities. Both groups reported that financial subsidies were the most important area for improvement. The greater importance of improvements to financial subsidies reported by caregivers predicted greater odds for self-efficacy for continuous community living. The greater importance of improvements to center-based services reported by individuals with disabilities predicted greater odds for self-efficacy for continuous community living. CONCLUSIONS: The findings suggested that financial subsidies for caregivers and center-based services for individuals with disabilities could improve self-efficacy for continuous community living.

OBJECTIVES: this study examined (i) the relationships between the care duration of carers and their perceptions of the importance of service improvement by types of service, and (ii) whether carers had a disability that moderated the impacts of care duration on these perceptions. DESIGN: survey data for cross-sectional analyses. METHOD: The sample consisted of carers without disability (n = 625) and carers with a disability (n = 77). Hierarchical multiple regression was applied to examine the unique contribution of care duration. The interaction effects of the disability status of the carer was also estimated. RESULTS: Longer care duration was associated with a greater perception of the importance of service improvement for certain services by carers. The positive relationships between care duration and perception of the importance of caregiver assistances and financial subsidy improvement were stronger for carers with disabilities compared to carers without disability. CONCLUSIONS: Long-term carers with disabilities face a potential double disadvantage of service improvement needs with more years of caregiving. Policy makers should consider prioritizing caregiver assistances or financial subsidy service improvements for long-term carers who themselves have a disability.

The current study aimed at exploring the relationship between self-stigma, readiness for change and psychosocial treatment adherence among individuals with schizophrenia. Between March 2007 and January 2008, 105 adults with schizophrenia were recruited for this cross-sectional study. Face-to-face interviews were conducted to assess participants' level of self-stigma, readiness for change, insight, and general self-efficacy. The corresponding case therapists reported participants' level of treatment adherence, psychopathology, and global functioning. Findings of stepwise multiple regression suggested that individuals with higher global functioning, better readiness for action, and lower level of self-stigma demonstrated better treatment participation. Individuals with lesser severity of psychiatric symptoms and female participants had better treatment attendance. The results of discriminant function analysis showed the combined score of self-stigma, stages of change, and global functioning measures correctly classified 76.2% participants into adherent/nonadherent group membership. Suggestions for further studies and development of self-stigma reduction program to facilitate recovery and treatment adherence were made.

BACKGROUND: In recent years, studies and reviews have reported the therapeutic benefits of both mindful and non-mindful exercises in reducing anxiety. However, there have not been any systematic reviews to compare their relative effectiveness for therapeutic application, especially among the non-clinical population. Thus, the aim of this review is to compare the effectiveness between mindful and non-mindful exercise on treating anxiety among non-clinical samples. METHODS: Potential articles were retrieved from PubMed, Embase, Academic Search Premier, and PsycInfo. Randomized controlled trials, which involved both mindful and non-mindful exercises as intervention, and the use of anxiety outcome measures were included. RESULTS: Twenty-four studies fulfilled the inclusion criteria and were included in our systematic review. In addition, 14 studies provided sufficient data to be included in the meta-analysis. For studies that reported significant group differences at post-assessment, results showed that mindful exercise was more beneficial in reducing anxiety than non-mindful exercise. The meta-analysis reported that yoga was more effective in reducing anxiety than non-mindful exercise. CONCLUSIONS: Compared to non-mindful exercise, yoga is shown to be more effective in alleviating anxiety symptoms. It is recommended that yoga could be used as a primary healthcare intervention to help the public reduce anxiety.

The adverse effects of depression on patients' life have been reported but information about its effects on the sequential organization of the information processing stages remains poorly understood as previous studies focused only on distinct stages. This study adds to existing knowledge by examining the effect of major depressive disorder (MDD) on the sequential organization of information processing, executive and community functioning. Fifty-seven participants with 19 participants each for first episode depression (FMDD), recurrent episodes depression (RMDD), and healthy controls (HCs) participated in this study. They completed assessments on executive and community functioning measures, and choice reaction time task (CRTT) for the event-related potential (ERP) data. Findings revealed no significant between-group difference in executive functioning but participants with depression (FMDD and RMDD) were found to be more depressed, with FMDD participants having worse community functioning skills compared with HCs. There was no significant between-group main effect on behavioral data. ERP data showed significantly less positive-going P3b among RMDD participants compared with HCs. FMDD participants used a different information processing strategy at P1, while HCs and RMDD participants used a different processing strategy at N2b compared with the other group(s), respectively. The results suggest the use of multifaceted assessment to get a holistic view of the health status of people with MDD in order to inform clinicians on the appropriate interventional strategies needed for the patient.
RESUMEN
BACKGROUND: Depression is a common disease affecting a large number of people across the world. Many researchers have focused on treatment for depression based on Western scientific approaches, but research based on traditional Chinese medicine (TCM) interventions, studying its clinical effectiveness and the underlying mechanisms involved, has been limited. The aim of this review is to conduct a pioneering systematic review with meta-analysis of existing studies that investigate the neuroscience basis of nonpharmacological traditional Chinese therapy (NTCT). METHODS: Both English (Pubmed, Embase, Scopus, SPORTDiscus, PsycINFO) and Chinese (China National Knowledge Infrastructure (CNKI)) databases were searched from inception to October 2018. The effects of NTCT on major depressive disorder, brain activity, and neurophysiological biomarker related outcomes were extracted. Study quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. The effect size of each study was reported by the mean difference of change scores. RESULTS: Six of twelve eligible studies showed that there was a significant improvement in favor of acupuncture in depressive symptoms (SMD -0.69, 95% CI -1.09 to -0.28, p=0.002, I 2 = 73%, p< 0.0008). Based on the available evidence, NTCT including acupuncture, Qigong, and Tai Chi was found to possibly improve brain metabolites, brain activity, and immune and endocrine systems in patients with major depressive disorder. CONCLUSIONS: Acupuncture could effectively relieve depressive syndromes. The clinical effects of acupuncture might be attributable to their influence on three proposed pathways, namely, the hypothalamic-pituitary-adrenal (HPA) axis, the locus coeruleus (LC)-immunity pathway, and the negative feedback loop of the hippocampus. Nevertheless, conclusions are limited due to the small number of studies included and the low-quality of the study designs. In the future, a cross-sectional study is needed to test the proposed plausible pathways. PROSPERO registration number is CRD42017080937.
RESUMEN
Objective: An increasing number of studies have shown the anti-depressive effect of qigong. However, its underlying mechanism remains poorly understood. This study aims to systematically review and meta-analyze existing literature on the mechanism of qigong in reducing depression. Method: The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials of qigong were searched from PsycINFO, PubMed, Embase, ScienceDirect, and Academic Search Premier from inception to December 2018. Studies which involved depression and any neurophysiological or psychological mechanisms as outcomes were included. Publication bias was tested before conducting meta-analysis. Two independent raters were involved for the entire review process. Results: A total of nine studies were identified which covered both neurophysiological and psychological mechanisms. Among these selected studies, seven were involved in meta-analysis, which suggested that qigong was effective in alleviating depression (standardized mean difference, SMD = -0.27, p < 0.05, I 2 = 27%). A significant effect was also found for diastolic blood pressure (SMD = -1.64, p < 0.05, I 2 = 31%). However, no significant effect was found for cortisol level and systolic blood pressure. Conclusions: This review shows that qigong is effective in reducing depression through activating the parasympathetic nervous system. Future studies with higher quality of research methodology with less selection and attrition bias should be conducted to unravel the possible anti-depressive effect of qigong.
RESUMEN
Depression is a major health issue that causes severe societal economic and health burden. Aromatherapy, a practice that uses essential oils for preventive and therapeutic purposes, represents a promising therapeutic alternative for the alleviation of depressive symptoms. Lavender essential oil (LEO) has been the focus of clinical studies due to its positive effect on mood. An animal model of chronic administration of high dose corticosterone to induce depression- and anxiety-like behavior and reduced neurogenesis was used to explore the biological changes brought by aromatherapy. Twenty-four adult male Sprague Dawley rats were randomly assigned into four groups: Control, corticosterone (Cort) group with high dose of corticosterone, LEO group with daily exposure to LEO by inhalation, and LEO + Cort. At the end of the 14-day treatment period, behavioral tests were carried out. Serum samples were collected 2-3 days after the 14-day period treatment and before perfusion to carry out biochemical analyses to measure BDNF, corticosterone and oxytocin. After perfusion, brains were collected for immunohistochemical analysis to detect BrdU and DCX positive cells in the hippocampus and subventricular zone. Results showed that treatment with LEO ameliorated the depression-like behavior induced by the chronic administration of corticosterone as observed in the LEO + Cort group. Cort treatment reduced the number of BrdU positive cells in the hippocampus and the subventricular zone. Treatment with LEO prevented the corticosterone-induced reduction in the number of BrdU positive cells (LEO + Cort group) demonstrating the neurogenic effect of LEO under high corticosterone conditions. Chronic administration of high dose of corticosterone significantly reduced the dendritic complexity of immature neurons. On the contrary, treatment with LEO increased dendritic complexity of immature neurons under high corticosterone conditions (LEO + Cort group). The improved neurogenesis and dendritic complexity observed in the LEO + Cort group demonstrated a clear restorative effect of LEO under high corticosterone conditions. However, 2-3 days after the treatment, the levels of BDNF were upregulated in the LEO and LEO + Cort groups. Furthermore, the concentration of oxytocin in serum, 2-3 days after the treatment, showed to be upregulated in the LEO group alone. The present study has provided evidence of the biological effect of LEO on neuroplasticity and neurogenesis. Also, this study contributes to the understanding of the mechanism of action of LEO in an animal model where depression- and anxiety-like behavior and reduced neurogenesis were induced by high corticosterone administration.

Background. Depression is one of the greatest health concerns affecting 350 million people globally. Aromatherapy is a popular CAM intervention chosen by people with depression. Due to the growing popularity of aromatherapy for alleviating depressive symptoms, in-depth evaluation of the evidence-based clinical efficacy of aromatherapy is urgently needed. Purpose. This systematic review aims to provide an analysis of the clinical evidence on the efficacy of aromatherapy for depressive symptoms on any type of patients. Methods. A systematic database search was carried out using predefined search terms in 5 databases: AMED, CINHAL, CCRCT, MEDLINE, and PsycINFO. Outcome measures included scales measuring depressive symptoms levels. Results. Twelve randomized controlled trials were included and two administration methods for the aromatherapy intervention including inhaled aromatherapy (5 studies) and massage aromatherapy (7 studies) were identified. Seven studies showed improvement in depressive symptoms. Limitations. The quality of half of the studies included is low, and the administration protocols among the studies varied considerably. Different assessment tools were also employed among the studies. Conclusions. Aromatherapy showed potential to be used as an effective therapeutic option for the relief of depressive symptoms in a wide variety of subjects. Particularly, aromatherapy massage showed to have more beneficial effects than inhalation aromatherapy.
