Meta-Analysis
PURPOSE
Hypertension is the primary cause of mortality. Hence globally, there is a growing interest in complementing antihypertensive drugs with herbs to alleviate blood pressure among hypertensive patients. Thus, this review aimed to evaluate the effectiveness of complementing drugs with herbs on blood pressure and lipid profile outcomes, the associated factors and the types of complementary herbs alongside their consumption regimes.
METHODS
This review is registered in PROSPERO on the National Institute of Health Database with an ID: CRD42021270481. Using the PICOS (population, intervention, comparison, outcome, study type) mnemonic formula and search strategy, we searched (January 2010 to February 2024) five electronic databases including Pubmed, Scopus, Web of Science, CINAHL (Cumulative Index for Nursing and Allied Health Literature) and Psychology & Behavioral Sciences Collection (PBSC). The inclusion criteria of the review were that all included papers had to be randomised control trials in English among hypertensive adults who complemented antihypertensive drugs with herbs. A Cochrane risk of bias assessment as well as a meta-analysis and narrative synthesis were conducted to answer the objectives.
RESULTS
Twenty-five randomised controlled trials involving 1996 participants from 14 countries were included. The risk of bias among included articles was assessed and presented using the Cochrane risk of bias tool and the graphs were generated. The effects of complementing antihypertensive drugs with different herb regimes on blood pressure and lipid profile outcomes were compared to those solely on antihypertensive drugs and placebo via a random model effects meta-analysis using the Revman manager. Systolic blood pressure (SBP) and triglycerides gave a significant reduction in favour of the intervention group which complemented herbs. The overall pooled systolic blood pressure showed a reduction of (SMD=0.81, 95 % CI 0.14-1.47, p < 0.02, p for heterogeneity=0.00001, I =97 %) while triglycerides were (SMD=0.73, 95 % CI 0.17-1.28, p < 0.01, p for heterogeneity=0.00001, I =85 %). However, diastolic blood pressure, total cholesterol, HDL and LDL did not exert significant outcomes.
CONCLUSION
The complemented herbs with antihypertensive drugs did show improvement in overall blood pressure management in the majority of the studies compared to the placebo group. Blood pressure and lipid profiles are the health outcomes that enable access to complementing herbs in controlling high blood pressure. Some limitations of this review are attributed to performance, detection and attrition bias in a few included articles alongside the presence of a high heterogeneity overall.

Global Health Action Dec 2024The use of Emergency Departments (EDs) for non-urgent medical conditions is a global public health concern. (Review)
Review
BACKGROUND
The use of Emergency Departments (EDs) for non-urgent medical conditions is a global public health concern.
OBJECTIVES
A systematic review, guided by a registered protocol (PROSPERO: CRD42023398674), was conducted to interpret the association between distance as a measure of healthcare access and the utilization of EDs for non-urgent care in high- and middle-income countries.
METHODS
The search was conducted on 22 August 2023 across five databases using controlled vocabulary and natural language keywords. Eligibility criteria included studies that examined non-urgent care, and featured concepts of emergency departments, non-urgent health services and distance, reported in English. Articles and abstracts where patients were transported by ambulance/paramedic services, referred/transferred from another hospital to an ED, or those that measured distance to an ED from another health facility were excluded. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework informed the quality of evidence.
RESULTS
Fifteen articles met the inclusion criteria. All studies demonstrated satisfactory quality with regard to study design, conduct, analysis and presentation of results. Eight (53.3%) of the studies (1 paediatric, 4 all ages/adult, 3 ecological) found a moderate level of evidence of an inverse association between distance and ED visit volume or utilization for non-urgent medical conditions, while the remaining studies reported very low or low evidence.
CONCLUSIONS
Half of the studies reported non-urgent ED use to be associated with shortest distance traveled or transportation time. This finding bears implications for healthcare policies aiming to reduce ED use for non-urgent care.

Review
BACKGROUND
Understanding the pivotal interplay between systemic and oral health is paramount to ensuring holistic care, particularly among the aging demographic. Therefore, this review article aims to explore the emerging concept of Rapid Oral Health Deterioration (ROHD) by reviewing the current knowledge base among older adults and identifying knowledge gaps in this area of research.
METHODS
This scoping review was conducted in line with Arksey and O'Malley's framework between December 2023 and March 2024 and reported while adhering to the PRISMA-ScR guidelines. A systematic database search was performed across three databases i.e. PubMed, Scopus, and EMBASE to collate the existing literature published in English between January 2013 and February 2024 addressing ROHD among older adults. After data charting, a critical appraisal of the selected studies was followed by qualitative thematic analysis.
RESULTS
Among the 12 papers in this scoping review, 10 were cross-sectional studies, with one each of retrospective cohort and case-control studies. The qualitative thematic analysis of the selected articles resulted in the emergence of four main themes: risk factors for ROHD, attributes related to ROHD, challenges encountered in the management of ROHD, and management approaches for ROHD among older adults.
CONCLUSIONS
This scoping review provides an overview of the rapid deterioration of oral health among older adults. Age-related dental disease harms the quality of life and overall health. To avoid dental disorders and to maintain and improve oral health in older adults, an integrated and multidisciplinary approach is essential. If ROHD is not treated, it may lead to poor health, a lower quality of life, and in severe cases, systemic infections that increase hospitalizations and possibly cause death.

Meta-Analysis
BACKGROUND
More than 57 million people have dementia worldwide. Evidence indicates a change in dementia prevalence and incidence in high-income countries, which is likely to be due to improved life-course population health. Identifying key modifiable risk factors for dementia is essential for informing risk reduction and prevention strategies. We therefore aimed to estimate the population attributable fraction (PAF) for dementia associated with modifiable risk factors.
METHODS
In this systematic review and meta-analysis, we searched Embase, MEDLINE, and PsycINFO, via Ovid, from database inception up to June 29, 2023, for population-derived or community-based studies and reviews reporting a PAF value for one or more modifiable risk factor for later-life dementia (prevalent or incident dementia in people aged ≥60 years), with no restrictions on dementia subtype, the sex or baseline age of participants, or the period of study. Articles were independently screened for inclusion by four authors, with disagreements resolved through consensus. Data including unweighted and weighted PAF values (weighted to account for communality or overlap in risk) were independently extracted into a predefined template by two authors and checked by two other authors. When five or more unique studies investigated a given risk factor or combination of the same factors, random-effects meta-analyses were used to calculate a pooled PAF percentage estimate for the factor or combination of factors. The review protocol was registered on PROSPERO, CRD42022323429.
FINDINGS
4024 articles were identified, and 74 were included in our narrative synthesis. Overall, PAFs were reported for 61 modifiable risk factors, with sufficient data available for meta-analysis of 12 factors (n=48 studies). In meta-analyses, the highest pooled unweighted PAF values were estimated for low education (17·2% [95% CI 14·4-20·0], p<0·0001), hypertension (15·8% [14·7-17·1], p<0·0001), hearing loss (15·6% [10·3-20·9], p<0·0001), physical inactivity (15·2% [12·8-17·7], p<0·0001), and obesity (9·4% [7·3-11·7], p<0·0001). According to weighted PAF values, low education (9·3% [6·9-11·7], p<0·0001), physical inactivity (7·3% [3·9-11·2], p=0·0021), hearing loss (7·2% [5·2-9·7], p<0·0001), hypertension (7·1% [5·4-8·8], p<0·0001), and obesity (5·3% [3·2-7·4], p=0·0001) had the highest pooled estimates. When low education, midlife hypertension, midlife obesity, smoking, physical inactivity, depression, and diabetes were combined (Barnes and Yaffe seven-factor model; n=9 studies), the pooled unweighted and weighted PAF values were 55·0% (46·5-63·5; p<0·0001) and 32·0% (26·6-37·5; p<0·0001), respectively. The pooled PAF values for most individual risk factors were higher in low-income and middle-income countries (LMICs) versus high-income countries.
INTERPRETATION
Governments need to invest in a life-course approach to dementia prevention, including policies that enable quality education, health-promoting environments, and improved health. This investment is particularly important in LMICs, where the potential for prevention is high, but resources, infrastructure, budgets, and research focused on ageing and dementia are limited.

Review
The neuromuscular junction (NMJ) is a specialized chemical synapse that converts neural impulses into muscle action. Age-associated NMJ degeneration, which involves nerve terminal and postsynaptic decline, denervation, and loss of motor units, significantly contributes to muscle weakness and dysfunction. Although physical training has been shown to make substantial modifications in NMJ of both young and aged animals, the results are often influenced by methodological variables in existing studies. Moreover, there is still lack of strong consensus on the specific effects of exercise on improving the morphology and function of the ageing NMJ. Consequently, the purpose of this study was to conduct a systematic review to elucidate the effects of exercise training on NMJ compartments in the elderly. We conducted a systematic review using PubMed, Embase, and Web of Science databases, employing relevant keywords. Two independent reviewers selected studies that detailed NMJ changes during exercise in ageing, written in English, and available in full text. In total, 20 papers were included. We examined the altered adaptation of the NMJ to exercise, focusing on presynaptic and postsynaptic structures and myofibers in older animals or humans. Our findings indicated that aged NMJs exhibited different adaptive responses to physical exercise compared to younger counterparts. Endurance training, compared with resistance and voluntary exercise regimens, was found to have a more pronounced effect on NMJ structural remodeling, particularly in fast twitch muscle fibers. Physical exercise was observed to promote the formation and maintenance of acetylcholine receptor (AChR) clusters by increasing the recombinant docking protein 7 (Dok7) expression and stabilizing Agrin and lipoprotein receptor-related protein 4 (LRP4). These insights suggest that research on exercise-related therapies could potentially attenuate the progression of neuromuscular degeneration. Translational potential of this article: This systematic review provides a detailed overview of the effects of different types of physical exercise on improving NMJ in the elderly, providing scientific support for the timely intervention of muscle degeneration in the elderly by physical exercise, and providing help for the development of new therapeutic interventions in the future.

Meta-Analysis
BACKGROUND
Coupled with its rising prevalence, Autism spectrum disorder (ASD) has become a globally recognized public health concern. Nevertheless, large-scale, multicenter studies that analyze the epidemiology of ASD in China are relatively scarce.
METHODS
Literature searches were conducted in PubMed/Medline, Embase, the Cochrane Library, Wanfang Data Knowledge Service Platform, China Biology Medicine database (CBM), China Science and Technology Journal Database (CSTJ), and China National Knowledge Infrastructure (CNKI) to retrieve studies published before April 8, 2023, related to ASD prevalence among children aged 0 to 14 years in mainland China. Meta-analysis was conducted using RevMan 5.2 and Stata 14.0.
RESULTS
Twenty-one articles were included. The ASD prevalence among children in mainland China has been 0.7% (95% confidence interval(CI): 0.006-0.008) since 2017. The prevalence of ASD among boys was 1.0% (95% CI: 0.008-0.011), which was significantly higher than that among girls at 0.2% (95% CI: 0.002-0.003), with a statistically significant difference (OR = 3.198, 95% CI: 2.489-4.109, P = 0.000). Among the included studies, 18 reported an ASD prevalence of 0.8% (95% CI: 0.007-0.010), while 3 studies reported an autistic disorder (AD) prevalence of 0.7% (95% CI: 0.006-0.008). The prevalence of autism among urban children was 23.9% (95% CI: 0.149-0.328), and in rural areas, it was 0.7% (95% CI: 0.002-0.013), with no statistically significant difference (OR = 1.342, 95% CI: 0.258-6.975, P = 0.727). Regression analysis showed that factors such as region (P = 0.000), age (P = 0.000), study period (P = 0.000), sample size (P = 0.000), sampling method (P = 0.002), population source (P = 0.000), disease type (P = 0.000), quality score of the study (P = 0.000), and diagnostic criteria (P = 0.000) might have contributed to the heterogeneity in ASD prevalence.
CONCLUSION
The prevalence of ASD in China from 2017 to 2023 was 7/1000, showing an upward trend compared to that before 2017 (26.50/10,000). The male-to-female prevalence ratio was 5:1.The overall prevalence remained significantly lower than that reported in foreign countries.

Meta-Analysis
AIM OF STUDY
This systematic review aimed to compare the physical-mechanical properties of 3D-printed (additively manufactured (AM)) zirconia compared to conventionally milled (subtractive manufactured: SM) zirconia specimens.
MATERIALS AND METHODS
A thorough search of Internet databases was conducted up to September 2023. The search retrieved studies that evaluated AM zirconia specimens and restorations regarding the physical-mechanical properties and mechanical behavior of zirconia. The main topic focused on 3Y-TZP. However, records of 4YSZ and 5YSZ were also included to gather more comprehensive evidence on additively manufactured zirconia ceramic. The quality of studies was assessed using the ROB2 tool, Newcastle Ottawa scale, and the Modified Consort Statement. Of 1736 records, 57 were assessed for eligibility, and 38 records were included in this review, only two clinical trials meet the inclusion criteria and 36 records were laboratory studies. There were no signs of mechanical complications and wear to antagonists with short-term clinical observation. SM thin specimens ≤1.5 mm showed statistically significant higher flexural strength than AM zirconia (p ≤ 0.01), while thicker specimens showed comparable outcomes (p > 0.5). The fracture resistance of dental restorations was dependent on the aging protocol, restoration type, and thickness. The bond strength of veneering ceramic to zirconia core was comparable.
CONCLUSIONS
The results pooled from two short-term clinical trials showed no signs of mechanical or biological complications of additively manufactured 3Y-TZP zirconia crowns. The flexural strength might depend on the specimens' thickness, but it showed promising results to be used in clinical applications, taking into account the printing technique and orientation, material composition (yttria content), solid loading, and sintering parameters. 3D-printed restorations fracture resistance improved when adhered to human teeth. The veneering ceramic bond was comparable to milled zirconia specimens. Long-term RCTs are recommended to confirm the mechanical behavior of 3D-printed restorations.

BACKGROUND
Postoperative delirium (POD) significantly affects patient outcomes after surgery, leading to increased morbidity, extended hospital stays, and potential long-term cognitive decline. This study assessed the predictive value of intraoperative electroencephalography (EEG) patterns for POD in adults.
METHODS
This systematic review and meta-analysis followed the PRISMA and Cochrane Handbook guidelines. A thorough literature search was conducted using PubMed, Medline, and CENTRAL databases focusing on intraoperative native EEG signal analysis in adult patients. The primary outcome was the relationship between the burst suppression EEG pattern and POD development.
RESULTS
From the initial 435 articles identified, 19 studies with a total of 7,229 patients were included in the systematic review, with 10 included in the meta-analysis (3,705 patients). In patients exhibiting burst suppression, the POD incidence was 22.1% vs. 13.4% in those without this EEG pattern (p=0.015). Furthermore, an extended burst suppression duration associated with a higher likelihood of POD occurrence ( = 0.016). Interestingly, the burst suppression ratio showed no significant association with POD.
CONCLUSIONS
This study revealed a 41% increase in the relative risk of developing POD in cases where a burst suppression pattern was present. These results underscore the clinical relevance of intraoperative EEG monitoring in predicting POD in older patients, suggesting its potential role in preventive strategies.

Meta-Analysis
The aging population warrants the increase of mild cognitive impairment (MCI) prevalence, a condition that could progress to dementia. Efforts have been made to improve the MCI and prevent its progression, including the introduction of Tai Chi, a Chinese traditional exercise. The aim of this systematic review and meta-analysis was to evaluate the efficacy of Tai Chi in attenuating MCI among the elderly population. Records investigating the effect of Tai Chi exercise intervention on cognitive function among elderly patients were searched systematically from PubMed, ScienceDirect, Google Scholar, and Europe PMC as of April 13, 2023. The risk of bias (RoB 2.0) quality assessment was employed in the quality appraisal of the studies included. Review Manager 5.4.1 was used for data extraction and meta-analysis, where the standard mean difference (SMD) and 95% confidence interval (95%CI) were computed. Eight randomized control trials with a total of 1379 participants were included in this meta-analysis. Six trials assessed Montreal Cognitive Assessment scores, where its pooled analysis suggested that Tai Chi was as effective as conventional exercise (SMD=0.15, 95%CI: -0.11 to 0.40, =0.26). However, pooled analysis of the Mini-Mental Status Examination suggested that Tai Chi intervention more effectively improved cognitive function and reduced the rate of cognitive impairment in elderly patients (SMD=0.36, 95%CI: 0.18 to 0.54, <0.01) as compared to the control group. This systematic review and meta-analysis suggest that, in some extent, Tai Chi is efficacious in improving cognitive function and slowing down the rate of cognitive impairment among elderly patients.

Review
INTRODUCTION
Frailty, marked by diminished physiological capacity and higher health risks, is less understood in middle-aged individuals (40-65 years) than older adults. This review synthesises intervention studies for pre-frailty and frailty in this demographic, assessing effectiveness, feasibility, and implementation factors including participant experience and cost-effectiveness.
METHOD
Registered on the Open Science Framework and adhering to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) and the template for intervention description and replication (TIDieR) guidelines, this review searched six databases for interventions targeting middle-aged adults. Dual screening, data extraction, risk assessment, and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) certainty evaluation were conducted. Findings were narratively synthesized due to heterogeneity.
RESULTS
Eight studies (2018-2023) with 2838 participants were included. Resistance training and multicomponent exercise reduced frailty; though, not always significantly. Low-intensity exercises and education-based interventions yielded mixed results, suggesting a need for further research. Positive participant experiences and cost-effectiveness of interventions such as resistance training and educational interventions supports their feasibility. Varying quality, methodologies and levels of bias indicated a need for more rigorous future research.
DISCUSSION
This review reveals an evidence gap in middle-aged frailty interventions. Multicomponent interventions and resistance training showed promise, but their comparative effectiveness remains uncertain. Educational and low-intensity interventions need further research to establish their effectiveness. The findings diverge from those in older adults, emphasising the need for age-specific approaches. Future studies should employ higher-quality methods and explore emerging technologies to enhance intervention effectiveness for pre-frailty and frailty in middle-aged adults.
