RESUMEN
OBJECTIVE: To determine the effects of simultaneous dual-task training on cognitive function, physical function, and depression in older adults with mild cognitive impairment or dementia. METHODS: Comprehensive database searches were conducted in PubMed, Embase, the Cochrane Library, CINAHL, Ovid-Medline, Web of Science, and Scopus up to December 2022. Randomized controlled trials were included to assess the efficacy of simultaneous dual-task training for older adults with mild cognitive impairment or dementia. The analysis utilized Comprehensive Meta-Analysis version 3.0, presenting Hedges' g and the corresponding 95â¯% confidence interval (CI) for the pooled effect size and, applying a random-effects model. The I2 and Cochran's Q tests were employed to evaluate heterogeneity. The Cochrane Risk of Bias 2.0 tool was employed to assess study quality. The Copenhagen Trial Unit (version 0.9.5.10 Beta) was employed for trial sequential analysis, providing a rigorous methodology for evaluating cumulative evidence from multiple studies. RESULTS: Of the 1676 studies identified, 20 studies involving 1477 older adults with cognitive impairment were included. Dual-task training significantly enhanced global cognition (0.477, 95â¯% CI: 0.282 to 0.671), executive function (-0.310, 95â¯% CI: -0.586 to -0.035), working memory (0.714, 95â¯% CI: 0.072 to 1.355), gait (0.418, 95â¯% CI: 0.252 to 0.583), physical activity (0.586, 95â¯% CI: 0.012 to 1.16), and depression (-0.703, 95â¯% CI: -1.253 to -0.153). Trial sequential analyses revealed the robustness of this meta-analysis, which was based on a sufficient sample size from the included studies. Moreover, dual-task training demonstrated beneficial effects on global cognition, executive function, working memory, and gait. CONCLUSIONS: Dual-task training improved cognition, physical function, and depression among older adults with cognitive impairment. Accordingly, dual-task training should be considered a clinical nonpharmacological intervention for older adults with mild cognitive impairment or dementia. Nevertheless, the trial sequential analysis results were consistent with those of the pairwise meta-analysis but only global cognition reached significance by crossing the trial sequential analysis boundary. Future studies with higher-quality designs and larger sample sizes are required to obtain more conclusive results regarding other outcomes. REGISTRATION: PROSPERO CRD42023418598.

BACKGROUND: Ageing process and abnormal protein accumulation in dementia damage neural pathways affecting the swallowing process and leading to swallowing disorder. OBJECTIVE: To estimate the prevalence of swallowing disorder among older adults with different dementia subtypes. METHODS: We conducted a systematic search across multiple databases, including PubMed, Embase, Scopus, Web of Science and OVID Medline. The meta-analysis employed R (version 4.0.2) and utilised a generalised linear mixed model with a random-effect approach to estimate the pooled prevalence of swallowing disorder among older adults, considering various dementia subtypes. The quality of included studies was assessed using Hoy's criteria. Heterogeneity was identified through Cochrane's Q and I2 statistics. To further explore heterogeneity, moderator analysis was performed to identify the contributing variables among the included studies. RESULTS: Eighteen studies with 12,532 older adults with different dementia subtypes were enrolled in our meta-analysis. The pooled prevalence of swallowing disorder among older adults with dementia was 58%, with 46.5% for Alzheimer's dementia, 34.9% for Parkinson's dementia, 18.8% for vascular dementia, 16.3% for mixed dementia and 12.2% for Lewy body dementia. According to assessment tools, Alzheimer's dementia had the highest prevalence, with 58% in instrumental assessments and 39% in clinical assessments. Medical history, Alzheimer's dementia, moderate-to-severe Clinical Dementia Rating, delayed oral phase, delayed pharyngeal phase and poor tongue motility contributed to the heterogeneity of the included studies. CONCLUSIONS: More than half of older adults with dementia demonstrate to have swallowing disorder. Our findings offer valuable insights to healthcare professionals for the identification of swallowing disorder in ageing population with dementia.

OBJECTIVE: Alterations in the suprachiasmatic nucleus due to underlying pathologies disrupt the circadian rhythms in people living with dementia (PLWD). Circadian rhythms significantly impact sleep, emotional, and cognitive functions, with its synchronization depending on light exposure. We performed a meta-analysis to evaluate the effects of light therapy on sleep, depression, neuropsychiatric behaviors, and cognition among PLWD. METHODS: A systematic search was conducted in Cochrane, ClinicalTrials.gov, Embase, EBSCOhost, Ovid-MEDLINE, PubMed, Scopus, Web of Science, and CINAHL databases. The pooled effect size was calculated using the Hedges' g with random-effects model adopted in comprehensive meta-analysis software. The Cochrane risk of bias (RoB 2.0) tool evaluated the quality of studies, while Cochrane's Q and I² tests assessed heterogeneity. RESULTS: A total of 24 studies with 1,074 participants were included. Light therapy demonstrated small-to-medium effects on improving sleep parameters: total sleep time (Hedges' g = 0.19), wake after sleep onset (Hedges' g = 0.24), sleep efficiency (Hedges' g = 0.31), sleep latency (Hedges' g = 0.35), circadian rhythm (acrophase: Hedges' g = 0.36; amplitude: Hedges' g = 0.43), number of night awakenings (Hedges' g = 0.37), sleep disturbance (Hedges'g = 0.45), and sleep quality (Hedges' g = 0.60). Light therapy showed small-to-medium effect on reducing depression (Hedges' g = -0.46) with medium-to-large effect on cyclical function (Hedges' g = -0.68) and mood-related signs and symptoms (Hedges' g = -0.84) subscales. Light therapy also demonstrated small effect on reducing neuropsychiatric behaviors (Hedges' g = -0.34) with medium-to-large effect on agitation (Hedges' g = -0.65), affective symptom (Hedges' g = -0.70), psychosis (Hedges' g = -0.72), and melancholic behavior (Hedges' g = -0.91) subscales. Additionally, light therapy also improved cognition (Hedges' g = 0.39). CONCLUSION: Light therapy could be used as a supportive therapy to improve sleep, depression, cognition, and neuropsychiatric behaviors among PLWD.

BACKGROUND: Aging and dementia are common and closely related health problems in older adults, affecting their ability to maintain a healthy diet and ultimately resulting in malnutrition. OBJECTIVE: In this study, we estimated the global prevalence of malnutrition and malnutrition risk in older adults with dementia. DESIGN: Meta-analysis. DATA SOURCES: Embase, Ovid MEDLINE, PubMed, CINAHL, Scopus, and Web of Science were comprehensively searched for articles published from database inception to October 2022. METHODS: Pooled prevalence analysis was conducted using a generalized linear mixed model and a random-effects model. I2 and Cochran's Q statistics were used for identifying heterogeneity. Publication bias was evaluated using Peters' regression test and a funnel plot. Moderator analyses were conducted to investigate variations in the prevalence estimates of the included studies. All statistical analyses were conducted using R software. RESULTS: A total of 16 studies involving a total of 6513 older adults with dementia were included in the analysis. The results indicated that 32.52â¯% (95â¯% confidence interval: 19.55-45.49) of all included older adults with dementia had malnutrition, whereas 46.80â¯% (95â¯% confidence interval: 38.90-54.70) had a risk of malnutrition. The prevalence of malnutrition was found to be high among older patients living in institutionalized settings (46.59â¯%) and those with Alzheimer's disease (12.26â¯%). The factors moderating the prevalence of malnutrition included adequate vitamin B12 consumption, risk behaviors, medical comorbidities, and certain neuropsychiatric symptoms. The prevalence of malnutrition risk was high among women (29.84â¯%) and patients with Alzheimer's disease (26.29â¯%). The factors moderating the prevalence of malnutrition risk included total cholesterol level, vitamin B12 consumption, risk behaviors, medical comorbidities, and certain neuropsychiatric symptoms. CONCLUSIONS: Approximately one-third of older adults with dementia are malnourished and nearly half of older adults are at a risk of malnutrition. Encouraging collaboration among health-care professionals and ensuring early assessment and effective management of malnutrition are crucial for maintaining a favorable nutritional status in older adults with dementia. REGISTRATION: This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42022369329). TWEETABLE ABSTRACT: Globally, approximately 32.52â¯% of older adults with dementia are malnourished and approximately 46.80â¯% are at a risk of malnutrition.

INTRODUCTION: People with dementia often experience behavioral and psychological symptoms of dementia (BPSD), which are a major cause of caregiver burden and institutionalization. Therefore, we conducted a double-blind, parallel-group randomized controlled trial to examine the efficacy of blue-enriched light therapy for BPSD in institutionalized older adults with dementia. METHODS: Participants were enrolled and randomly allocated into blue-enriched light therapy (N = 30) or the conventional light group (N = 30) for 60 min in 10 weeks with five sessions per week. The primary outcome was sleep quality measured by actigraphy and Pittsburgh Sleep Quality Index (PSQI). The secondary outcome was overall BPSD severity (Cohen-Mansfield Agitation Inventory [CMAI] and Neuropsychiatric Inventory [NPI-NH]). The outcome indicators were assessed at baseline, mid-test, immediate posttest, 1-month, 3-month, and 6-month follow-up. The effects of the blue-enriched light therapy were examined by the generalized estimating equation model. RESULTS: Blue-enriched light therapy revealed significant differences in the objective sleep parameters (sleep efficiency: ß = 5.81, Waldχ2 = 32.60, CI: 3.82; 7.80; sleep latency: ß = -19.82, Waldχ2 = 38.38, CI:-26.09; -13.55), subjective sleep quality (PSQI: ß = -2.07, Waldχ2 = 45.94, CI: -2.66; -1.47), and overall BPSD severity (CMAI: ß = -0.90, Waldχ2 = 14.38, CI: -1.37; -0.44) (NPI-NH: ß = -1.67, Waldχ2 = 30.61, CI: -2.26; -1.08) compared to conventional phototherapy immediate posttest, 1-month, 3-month, and 6-month follow-up. Furthermore, the effects for sleep efficiency and sleep latency lasted for up to 6 months. In the subscale analysis, the differences of the behavioral symptoms changed significantly between the groups in physical/nonaggressive (CI: -1.01; -0.26) and verbal/nonaggressive (CI: -0.97; -0.29). CONCLUSIONS: Blue-enriched light therapy is a feasible low-cost intervention that could be integrated as a comprehensive therapy program for BPSD among older adults with dementia.
RESUMEN
Background: Attention is essential to daily life and cognitive functioning, and attention deficits can affect daily functional and social behaviour, such as falls, risky driving, and accidental injuries. However, attention function is important yet easily overlooked in older adults with mild cognitive impairment, and evidence is limited. We aimed to explore the pooled effect of cognitive training on domains of attention in older adults with mild cognitive impairment and mild dementia using a meta-analysis of randomised controlled trials. Methods: We searched PubMed, Embase, Scopus, Web of Science, CINAHL, PsycINFO, and Cochrane Library for randomised controlled trials (RCTs) up to 3 November 2022. We included participants aged ≥50 years diagnosed with cognitive impairment, with various cognitive training interventions as the intervention measures. The primary outcome was overall attention and the secondary outcomes were attention in different domains and global cognitive function. We calculated the Hedges' g and confidence intervals (CIs) using a random-effects model to evaluate the effect size of the outcome measures and evaluated heterogeneity using the χ2 test and I2 value. Results: We included 17 RCTs and found that cognitive training interventions improve overall attention (Hedges' g = 0.41; 95% CI = 0.13, 0.70), selective attention (Hedges' g = 0.37; 95% CI = 0.19, 0.55), divided attention (Hedges' g = 0.38; 95% CI = 0.03, 0.72), and global cognitive function (Hedges' g = 0.30; 95% CI = 0.02, 0.58) in older adults with mild cognitive impairment, but with relatively low effectiveness. Conclusions: Cognitive training intervention can improve some attention functions in older adults with mild cognitive impairment. Attention function training should also be incorporated into routine activities and long-term sustainability planning to delay the deterioration of attention function in older adults. Besides reducing their risk of abnormal events in daily life (such as falls), it can also improve their quality of life and help reduce the progression of cognitive impairment, achieving early detection of secondary prevention.

Background: Cognitive function, working memory, attention, and coordination are higher-level functions sharing a complex relationship. Limited evidence exists on the effectiveness of multi-domain cognitive function interventions to improve cognitive outcomes. We evaluated the effectiveness of such interventions on cognitive function, working memory, attention, and coordination in older adults with mild cognitive impairment and mild dementia. Methods: We conducted a double-blind, two-arm, parallel-group randomised controlled trial in community care centres of Northern Taiwan. We recruited 72 participants aged≥65 years and randomly allocated them using 1:1 block randomization (block size = 4) into experimental (multi-domain cognitive function training) (MCFT) and control groups (passive information activities) (PIA) (n = 36/group). We administered the interventions in both groups for 30 minutes per session, three sessions per week for eight weeks, for a total of 24 sessions. The outcome indicators were cognitive function assessed (mini-mental status examination), working memory (digit span), selective attention (Stroop test), visual-spatial attention (trail making test-A (TMT-A)), divided attention (trail making test-B (TMT-B)), and coordination (Berry visual-motor integration (Berry-VMI)). We evaluated the study outcomes at baseline, immediate post-test, one-month follow-up, and one-year follow-up. Results: We found no significant differences between the groups at baseline except for education. The average age of participants was 82.3 years, and most (76.4%) were female. We analysed the results by generalised estimating equations (GEE) based on the intention-to-treat (ITT) principle. The multi-domain cognitive function training was effective in improving cognitive function (ß = 1.7; 95% confidence interval (CI) = 0.63-2.31; P = 0.001), working memory (ß = -1.45; 95% CI = -2.62, -0.27; P = 0.016), and selective attention (ß = -23.3; 95% = CI -43.9, -2.76; P = 0.026) compared to passive information activities at 1-month follow-up. The effects of multi-domain cognitive function training on cognitive function (ß = 1.51; 95% CI = 0.40-2.63; P = 0.008), working memory (ß = -1.93; 95% CI -3.33, -0.54; P = 0.007), selective attention (ß = -27.8; 95% CI = -47.1, -8.48; P = 0.005), and coordination (ß = 1.61; 95% CI = 0.25, 2.96; P = 0.020) were maintained for one year. There were no significant improvements in attention outcomes (visual-spatial and divided attention) after training. Conclusions: MCFT intervention demonstrated favourable effects in improving global cognitive function, working memory, selective attention, and coordination among older adults with mild cognitive impairment and mild dementia. Thus, applying multi-domain cognitive training in older adults with mild cognitive impairment and mild dementia could help to delay the cognitive decline.

BACKGROUND: Increasing patient awareness of post-discharge care resources is an effective strategy to reduce rehospitalization rates and medical costs. Therefore, the purpose of this study was to explore hospitalized older adult patients' awareness of and subjective demands for post-discharge healthcare services. METHODS: A cross-sectional study design was conducted from November 2018 to May 2020. STROBE statement was completed. Participants were inpatients over 65 years of age in the general ward of a medical center in northern Taiwan. A questionnaire was used to collect data by face-to-face interviews. Two hundred and twelve participants were recruited. Home nursing care, home rehabilitation, home respiratory therapy, home services, assistive devices rental, and transportation were the main post-discharge healthcare services in this study. RESULTS: Overall, 83.5% of older adult patients were aware of and 55.7% of the older adult patients demanded at least one post-discharge healthcare services. Logistic regression results found that, patients experiencing moderate to severe disability and cognitive impairment, and those hospitalized in the past year had significantly higher demands for services. CONCLUSIONS: Developing post-discharge healthcare services for older adult patients provides continuous patient-centered services for assisting patients and their families in adapting to the transition period of the post-acute stage. Satisfying these demands is beneficial for older adult patients and their families, as well as for reducing readmissions and medical costs.
RESUMEN
OBJECTIVE: To estimate the global prevalence of low resilience among the general population and health professionals during the COVID-19 pandemic. METHODS: Embase, Ovid-MEDLINE, PubMed, Scopus, Web of Science, CINAHL, WHO COVID-19 databases, and grey literature were searched for studies from January 1, 2020, to August 22, 2022. Hoy's assessment tool was used to assess for risk of bias. Meta-analysis and moderator analysis was performed using the Generalized Linear Mixed Model with a corresponding 95 % confidence interval (95 % CI) adopting the random-effect model in R software. Between-study heterogeneity was measured using I2 and τ2 statistics. RESULTS: Overall, 44 studies involving 51,119 participants were identified. The pooled prevalence of low resilience was 27.0 % (95 % CI: 21.0 %-33.0 %) with prevalence among the general population being 35.0 % (95 % CI: 28.0 %-42.0 %) followed by 23.0 % (95 % CI: 16.0 %-30.9 %) for health professionals. The 3-month trend analysis of the prevalence of low resilience beginning January 2020 to June 2021 revealed upward then downward patterns among overall populations. The prevalence of low resilience was higher in females, studied during the delta variant dominant period, frontline health professionals, and undergraduate degree education. LIMITATIONS: Study outcomes showed high heterogeneity; however, sub-group and meta-regression analyses were conducted to identify potential moderating factors. CONCLUSIONS: Globally, 1 out of 4 people among the general population and health professionals experienced low resilience due to COVID-19 adversity. The prevalence of low resilience was twice as much among the general population compared to health professionals. These findings provide information for policymakers and clinicians in the development and implementation of resilience-enhancing programs.

AIM: Examine effectiveness of respiratory rehabilitation and moderating factors on lung function and exercise capacity in post-COVID-19 patients. DESIGN: Meta-analysis. METHODS: R software 4.0.2 assessed the effectiveness of respiratory rehabilitation adopting the random-effects model and presenting standardised mean differences (SMDs). Heterogeneity was determined by Cochran's Q and I2 . The Cochrane Risk of Bias 2.0 and MINORS evaluated quality of the included studies. DATA SOURCES: A comprehensive search was undertaken in Cochrane, Embase, Ovid-MEDLINE, Scopus, NCBI SARS-CoV-2 Resources, ProQuest, Web of Science and CINAHL until March 2022. RESULTS: Of the 5703 identified studies, 12 articles with 596 post-COVID-19 patients were included. Eleven of our twelve studies had moderate to high quality and one study had high risk of bias assessed with MINORS and RoB 2 tool. Overall, respiratory rehabilitation was effective in improving forced expiratory volume in 1 s (1.14; 95%CI 0.39-1.18), forced vital capacity (0.98; 95%CI 0.39-1.56), total lung capacity (0.83; 95%CI 0.22-1.44), 6-minute walk distance (1.56; 95%CI 1.10-2.02) and quality of life (0.99; 95%CI 0.38-1.60). However, no significant differences were observed for ratio of the forced expiratory volume in 1 s to the forced vital capacity of the lungs, anxiety and depression. Respiratory rehabilitation for post-COVID-19 patients was effective in those without comorbidities, performed four types of exercise programs, frequency ≥3 times/week and rehabilitation time 6 weeks. CONCLUSIONS: Respiratory rehabilitation improved lung function, exercise capacity and quality of life in post-COVID-19 patients. The findings suggest rehabilitation programs for post-COVID-19 patients should use multiple respiratory exercise programs with frequency of ≥3 times per week for longer than 6 weeks. IMPACT: These findings will help improve the implementation of respiratory rehabilitation programs for post-COVID-19 patients. IMPLICATIONS FOR THE PROFESSION: Our findings can be used to develop patient-centred respiratory rehabilitation interventions by nurses and clinicians for post-COVID-19 patients. REPORTING METHOD: PRISMA guideline was followed. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Millions of people worldwide are mourning the loss of loved ones due to the COVID-19 epidemic, which may adversely impact their mental health. This meta-analysis aimed to investigate pandemic grief symptoms and disorders for developing policy, practice, and research priorities. The databases of Cochrane, Embase, Ovid-MEDLINE, WHO COVID-19, NCBI SARS-CoV-2, Scopus, Web of Science, CINAHL, and Science Direct were comprehensively searched until July 31, 2022. The Joanna Briggs Institute's and Hoy's criteria were used to evaluate the studies. A pooled prevalence was presented in a forest plot figure with a corresponding 95% confidence interval (CI) and prediction interval. Between-study heterogeneity was measured using the I2 and Q statistics. Variations in the prevalence estimates in different subgroups were examined by moderator meta-analysis. The search identified 3677 citations, of which 15 studies involving 9289 participants were included in the meta-analysis. The pooled prevalence rate of grief symptoms was 45.1% (95%CI: 32.6%-57.5%), and grief disorder was 46.4% (95%CI: 37.4%-55.5%). Grief symptoms were significantly higher in <6 months (45.8%; 95%CI: 26.3%-65.3%) compared to the period of more than 6 months. Unfortunately, moderator analyses for grief disorders could not be performed due to limited studies. The prevalence of grief problems during the pandemic was substantially higher than in non-pandemic conditions; therefore, it is crucial to strengthen bereavement support to reduce psychological distress. The results provide a foundation for nurses and healthcare workers to anticipate a heightened need for support and provision of bereavement care in the post-pandemic era.

OBJECTIVE: Sleep-related breathing disorders (SRBD) have shown to cause worsened cognitive impairment among people with dementia. Therefore, we conducted the first meta-analysis to estimate the prevalence of SRBD among people with dementia. METHODS: Comprehensive searches were conducted in Embase, Ovid-MEDLINE, PubMed, PsycINFO, Scopus, Web of Science, and CINAHL. The generalized linear mixed model (GLMM) was used for the pooled prevalence analysis and heterogeneity using I2 test and Cochran's Q-statistic in R-software. Study quality was assessed by Hoy's risk of bias assessment tool. Overall, 20 studies from 1282 studies were included with 1461 participants. RESULTS: The pooled prevalence of SRBD among dementia was 59% (95%CI: 44%-73%) with 55% (95%CI: 34%-74%) for obstructive sleep apnea (OSA), 49% (95%CI: 25%-73%) for unspecified SRBD, and 11% (95%CI: 5%-21%) for central sleep apnea (CSA). Regarding dementia subtypes, the prevalence of SRBD was 89% (95%CI: 61%-97%) for Alzheimer's dementia, 56% (95%CI: 48%-63%) for Parkinson's and Idiopathic Parkinson's dementia, and 16% (95%CI: 8%-30%) for Huntington's dementia. Significant moderator variables were male, body mass index, larger waist and hip circumference, waist-hip ratio, and comorbidities including hypertension, dyslipidemia, renal disease, diabetes, heart disease, and stroke. CONCLUSIONS: There is considerable high prevalence of SRBD among dementia people, with OSA and unspecified SRBD being fivefold higher than CSA. Regarding dementia subtypes, Parkinson's and Idiopathic Parkinson's, and Alzheimer's dementia had four to sixfold increased risk of presenting with SRBD than Huntington's dementia. Therefore, assessment and management of SRBD in Alzheimer's, and Parkinson's and Idiopathic Parkinson's dementia deserves more attention in future research.

BACKGROUND: Evidence on the long-term comparative effectiveness of posttraumatic stress disorder (PTSD) psychotherapies in adults remains unknown. Therefore, we performed an extensive network meta-analysis of randomised controlled trials (RCTs) to determine the comparative effectiveness of psychotherapies for people diagnosed with PTSD. METHODS: A comprehensive search was conducted in Cochrane library, Embase, Medline-OVID, PubMed, Scopus, and Psych-Info until March 2021. Studies on the effectiveness of cognitive processing therapy (CPT), cognitive therapy (CT), eye movement desensitisation reprocessing (EMDR), narrative exposure therapy (NET), prolonged exposure (PE), cognitive behavioural therapy (CBT), present-centred therapy (PCT), brief eclectic psychotherapies (BEP), psychodynamic therapy (PDT) or combination therapies compared to no treatment (NT) or treatment as usual (TAU) in adults with PTSD were included. Frequentist and Bayesian approaches were used for analysis in R-software. RESULTS: We included 98 RCTs with 5567 participants from 18 897 studies. CPT, EMDR, CT, NET, PE, CBT, and PCT were significant to reduce PTSD symptoms (SMD range: -1.53 to -0.75; Certainty: very low to high) at immediate post-treatment and ranked accordingly. Longitudinal analysis found EMDR (1.02) and CPT (0.85) as the significant therapies with large effect size in short-term and long-term follow-up, respectively. NET and CPT showed higher proportion of loss of PTSD diagnosis (RR range: 5.51-3.45) while there were no significant psychotherapies for retention rate compared to NT. CONCLUSIONS: Our findings provide evidence for improving current guidelines and informing clinical decision-making for PTSD management. However, the best PTSD treatment plan should be tailored to patients' needs, characteristics, and clinician expertise. REGISTRATION: PROSPERO CRD42020162143.

Background: Post-extubation and neurologic complications in COVID-19 patients have been shown to cause oropharyngeal dysphagia (OD). We performed the first meta-analysis to explore and estimate the pooled prevalence of OD, risk of mortality, and associated factors among hospitalized COVID-19 patients. Methods: We searched Scopus, PubMed, Embase, CINAHL, WHO COVID-19 database, and Web of Science for literature on dysphagia in COVID-19 patients. We used the generalized linear mixed model (GLMM) to determine the prevalence estimates of OD in the R software and the DerSimonian-Lard random-effects model in the Comprehensive Meta-Analysis software to explore the risk of mortality and associated factors of OD, presented as odds ratios (ORs) and corresponding 95% confidence intervals (CIs). We used Cochran's Q, τ2, and the I2 statistic to assess heterogeneity and conducted a moderator analysis to identify moderator variables. Results: We included eighteen studies with a total of 2055 participants from the 910 studies retrieved from electronic databases. The prevalence of OD among hospitalized COVID-19 patients was estimated at 35% (95% CI = 21-52; low certainty of evidence) associated with a high risk of mortality (OR = 6.41; 95% CI = 1.48-27.7; moderate certainty of evidence). Intubation (OR = 16.3; 95% CI = 7.10-37.3; high certainty of evidence), use of tracheostomies (OR = 8.09; 95% CI = 3.05-21.5; high certainty of evidence), and proning (OR = 4.97; 95% CI = 1.34-18.5; high certainty of evidence) among hospitalized COVID-19 patients were highly associated with developing OD. The prevalence of OD was higher among hospitalized COVID-19 patients who were admitted in intensive care units (ICU), intubated, and mechanically ventilated. Conclusions: The prevalence of OD among hospitalized COVID-19 patients is estimated at 35% associated with a high risk of mortality. OD assessment among hospitalized COVID-19 patients who are managed in an ICU, prone position, intubated, and mechanical ventilated deserves more attention. Registration: PROSPERO CRD42022337597.

Background: Shift work and irregular work schedules among first responders have been associated with physical and psychological problems such as sleep disorders. We conducted the first meta-analysis to explore and estimate the prevalence of sleep disorders among first responders for medical emergencies. Methods: We searched four databases: Web of Science, Psych Info, CINAHL, and PubMed. The Generalized Linear Mixed model (GLMM) was used to estimate the prevalence estimates of sleep disorders in R software and the DerSimonian-Lard random-effects model in Comprehensive Meta-Analysis was used to explore associated comorbidities for OSA and insomnia, presented as odds ratios (ORs) and confidence intervals (CIs). The Cochran's Q, τ2, and the statistics were used to assess heterogeneity and the moderator analysis was conducted to identify moderator variables. Results: Twenty-eight studies with 100 080 first responders were included from the total of 1119 studies retrieved from the databases. The prevalence rates for sleep disorders were 31% (95% CI = 15%-53%) for shift work disorder (SWD), 30% (95% CI = 18%-46%) for obstructive sleep apnea (OSA), 28% (95% CI = 19%-39%) for insomnia, 28% (95% CI = 24%-33%) for excessive daytime sleepiness (EDS), 2% (95% CI = 1%-4%) for restless leg syndrome, and 1% (95% CI = 0%-5%) for narcolepsy. Anxiety (OR = 2.46; 95% CI = 1.99%-3.03%), cardiovascular disease (CVD) (OR = 2.03; 95% CI = 1.43-2.88), diabetes mellitus (DM) (OR = 1.93; 95% CI = 1.41-2.65), depression (OR = 1.89; 95% CI = 1.01-3.56), gastroesophageal reflux disease (GERD) (OR = 1.83; 95% CI = 150-2.22), and post-traumatic stress disorder (PTSD) (OR = 1.78; 95% CI = 1.33-2.39) were associated with OSA. Depression (OR = 9.74; 95% CI = 4.67-20.3), anxiety (OR = 9.22; 95% CI = 3.81-22.3), and PTSD (OR = 7.13; 95% CI = 6.27-8.10) were associated with insomnia. Age, gender, first responders, continent, study quality, study design, and assessment tool were significant moderator variables for OSA, insomnia, and EDS. Conclusions: This meta-analysis found a substantially high prevalence of sleep disorders including SWD, OSA, insomnia, and EDS among first responders for medical emergencies. Early assessment and management of sleep disorders among first responders is necessary to promote good, quality sleep to help prevent anxiety, depression, CVD, DM, GERD, and PTSD.

Background: The COVID-19 pandemic has been shown to cause enormous psychological burden among health care workers, including first responders. However, psychological well-being of first responders, essential in the fight against COVID-19 pandemic, has often been ignored. We performed the first meta-analysis to explore the prevalence of 1) depression, 2) anxiety, and 3) stress among first responders for medical emergencies during the COVID-19 pandemic. Methods: A comprehensive search was conducted in Embase, CINAHL, Web of Science, PsychInfo, PubMed, and the WHO COVID-19 database from 2020. The Freeman-Tukey double-arcsine transformation model in R-software determined the pooled prevalence and Comprehensive Meta-Analysis for associated factors of depression, anxiety, and stress with corresponding 95% confidence intervals (CI). The Cochrane Q, τ2, and I2 statistics were used to examine heterogeneity. Sub-group analysis was conducted to identify moderator variables. Results: We identified 765 records, from which 17 studies were included with 8096 first responders. The pooled prevalence was 31% (95% CI = 21%-41%) for depression; 67% (95% CI = 64%-70%) for mild depression, 24% (95% CI = 17%-31%) for moderate depression, and 16% (95% CI = 4%-34%) for severe depression. The pooled prevalence for anxiety was 32% (95% CI = 20%-44%); 60% (95% CI = 46%-73%) for mild anxiety, 27% (95% CI = 14%-42%) for moderate anxiety, and 14% (95% CI = 7%-22%) for severe anxiety. The pooled prevalence for stress was 17% (95% CI = 4%-34%); 58% (95% CI = 38%-77%) for mild stress, 22% (95% CI = 5%-44%) for moderate stress, and 19% (95% CI = 5%-37%) for severe stress. The prevalence of depression was 37% (95% CI = 25%-52%) for paramedics, 28% (95% CI = 12%-54%) for EMS personnel and 22% (95% CI = 13%-33%) for police. Similarly, the prevalence of anxiety was 38% (95% CI = 20%-60%) for paramedics, 28% (95% CI = 11%-53%) for EMS personnel, and 19% (95% CI = 10%-32%) for police. Married responders were likely at risk for depression (1.50, 95% CI = 1.26-1.78) and anxiety (1.94, 95% CI = 1.62-2.33), while unmarried responders were less likely at risk for depression (0.67, 95% CI = 0.56-0.79) and anxiety (0.50, 95% CI = 0.43-0.63). Conclusions: High prevalence of depression, anxiety, and stress during the COVID-19 pandemic among first responders for medical emergencies emphasizes the need for monitoring their psychological well-being. Early assessment and management of mild depression, anxiety, and stress among first responders are crucial in preventing progression into moderate and severe types.

OBJECTIVES: To examine the effectiveness of prone positioning on COVID-19 patients with acute respiratory distress syndrome with moderating factors in both traditional prone positioning (invasive mechanical ventilation) and awake self-prone positioning patients (non-invasive ventilation). RESEARCH METHODOLOGY: A comprehensive search was conducted in CINAHL, Cochrane library, Embase, Medline-OVID, NCBI SARS-CoV-2 Resources, ProQuest, Scopus, and Web of Science without language restrictions. All studies with prospective and experimental designs evaluating the effect of prone position patients with COVID-19 related to acute respiratory distress syndrome were included. Pooled standardised mean differences were calculated after prone position for primary (PaO2/FiO2) and secondary outcomes (SpO2 and PaO2) RESULTS: A total of 15 articles were eligible and included in the final analysis. Prone position had a statistically significant effect in improving PaO2/FiO2 with standardised mean difference of 1.10 (95%CI 0.60-1.59), SpO2 with standardised mean difference of 3.39 (95% CI 1.30-5.48), and PaO2 with standardised mean difference of 0.77 (95% CI 0.19-1.35). Patients with higher body mass index and longer duration/day are associated with larger standardised mean difference effect sizes for prone positioning. CONCLUSIONS: Our findings demonstrate that prone position significantly improved oxygen saturation in COVID-19 patients with acute respiratory distress syndrome in both traditional prone positioning and awake self-prone positioning patients. Prone position should be recommended for patients with higher body mass index and longer durations to obtain the maximum effect.

BACKGROUND: Post-stroke dysphagia (PSD) has been associated with high risk of aspiration pneumonia and mortality. However, limited evidence on pooled prevalence of post-stroke dysphagia and influence of individual, disease and methodological factors reveals knowledge gap. Therefore, to extend previous evidence from systematic reviews, we performed the first meta-analysis to examine the pooled prevalence, risk of pneumonia and mortality and influence of prognostic factors for PSD in acute stroke. METHODS: Our search was conducted in CINAHL, Cochrane Library, EMBASE, Ovid-Medline, PubMed, and Web of Science an initial search in October 2020 and a follow-up search in May 2021. Data synthesis was conducted using the Freeman-Tukey double-arcsine transformation model for the pooled prevalence rate and the DerSimonian-Lard random-effects model for prognostic factors and outcomes of PSD. RESULTS: The pooled prevalence of PSD was 42% in 42 studies with 26,366 participants. PSD was associated with higher pooled odds ratio (OR) for risk of pneumonia 4.08 (95% CI, 2.13-7.79) and mortality 4.07 (95% CI, 2.17-7.63). Haemorrhagic stroke 1.52 (95% CI, 1.13-2.07), previous stroke 1.40 (95% CI, 1.18-1.67), severe stroke 1.38 (95% CI, 1.17-1.61), females 1.25 (95% CI, 1.09-1.43), and diabetes mellitus 1.24 (95% CI, 1.02-1.51) were associated with higher risk of PSD. Males 0.82 (95% CI, 0.70-0.95) and ischaemic stroke 0.54 (95% CI, 0.46-0.65) were associated with lower risk of PSD. Haemorrhagic stroke, use of instrumental assessment method, and high quality studies demonstrated to have higher prevalence of PSD in the moderator analysis. CONCLUSIONS: Assessment of PSD in acute stroke with standardized valid and reliable instruments should take into account stroke type, previous stroke, severe stroke, diabetes mellitus and gender to aid in prevention and management of pneumonia and thereby, reduce the mortality rate.

BACKGROUND: The ChAdOx1 nCoV-19 vaccine has been widely administered against SARS-CoV-2 infection; however, data regarding its immunogenicity, reactogenicity, and potential differences in responses among Asian populations remain scarce. METHODS: 270 participants without prior COVID-19 were enrolled to receive ChAdOx1 nCoV-19 vaccination with a prime-boost interval of 8-9 weeks. Their specific SARS-CoV-2 antibodies, neutralizing antibody titers (NT50), platelet counts, and D-dimer levels were analyzed before and after vaccination. RESULTS: The seroconversion rates of anti-RBD and anti-spike IgG at day 28 after a boost vaccination (BD28) were 100% and 95.19%, respectively. Anti-RBD and anti-spike IgG levels were highly correlated (r = 0.7891), which were 172.9 ± 170.4 and 179.3 ± 76.88 BAU/mL at BD28, respectively. The geometric mean concentrations (GMCs) of NT50 for all participants increased to 132.9 IU/mL (95% CI 120.0-147.1) at BD28 and were highly correlated with anti-RBD and anti-spike IgG levels (r = 0.8248 and 0.7474, respectively). Body weight index was statistically significantly associated with anti-RBD IgG levels (p = 0.035), while female recipients had higher anti-spike IgG levels (p = 0.038). The GMCs of NT50 declined with age (p = 0.0163) and were significantly different across age groups (159.7 IU/mL for 20-29 years, 99.4 IU/mL for ≥50 years, p = 0.0026). Injection-site pain, fever, and fatigue were the major reactogenicity, which were more pronounced after prime vaccination and in younger participants (<50 years). Platelet counts decreased and D-dimer levels increased after vaccination but were not clinically relevant. No serious adverse events or deaths were observed. CONCLUSION: The vaccine is well-tolerated and elicited robust humoral immunity against SARS-CoV-2 after standard prime-boost vaccination in Taiwanese recipients.
RESUMEN
INTRODUCTION: Oropharyngeal dysphagia (OD) is a serious health condition associated with poor survival and quality of life in adults aged 60 years and older. Comprehensive assessment and management of OD could lead to better and improved health outcomes for older adults. Therefore, we performed the first meta-analysis to determine the pooled prevalence of OD and risk of pneumonia, malnutrition, and mortality. METHODS: Databases including Ovid-MEDLINE, Web of Science, Embase, PubMed, Cochrane, and CINAHL were searched up to January 2021. Data analysis was conducted using logistic-normal for prevalence rate and DerSimonian-Lard random-effects models for outcomes and associated factors of OD, providing odds ratio (OR) and corresponding 95% confidence interval (CI). RESULTS: The pooled prevalence of OD in 39 studies with 31,488 participants was 46% associated with higher pooled OR for risk of pneumonia 2.07 (95% CI, 1.58-2.72), malnutrition 2.21 (95% CI, 1.43-3.41), and mortality 2.73 (95% CI, 1.62-4.60). Geriatric syndromes including fecal incontinence 6.84 (4.955-9.44), immobility syndrome 6.06 (5.28-6.96), pressure ulcers 4.02 (2.46-6.56), sarcopenia 3.10 (1.89-5.09), urinary incontinence 2.75 (1.81-4.19), frailty 2.66 (1.16-6.13), delirium 2.23 (1.73-2.87), and falls 1.47 (1.19-1.81) and comorbidities including dementia 3.69 (2.36-5.78) and stroke 1.92 (1.47-2.52) were associated with OD. CONCLUSION: Early identification and management of OD should consider geriatric syndromes and neurogenic comorbidities to prevent malnutrition and pneumonia and reduce mortality in adults aged 60 years and older.
