Meta-Analysis
BACKGROUND
Exposure to pesticides is a global public health problem, especially for children. Its association with chronic respiratory disease among children has attracted considerable attention, but the existing evidence remains inconclusive and cannot be certain. Therefore, this systematic review and meta-analysis aim to determine the global pooled effect size of association with pesticide exposure and asthma, wheezing, and respiratory tract infections among children.
METHODS
A comprehensive search was conducted for relevant literature from electronic databases, including PubMed, Google Scholar, Hinari, Semantic Scholar, and Science Direct. Studies that provided effect size on the association between pesticide exposure and childhood asthma, wheezing, and respiratory tract infections in children were included. The articles were screened, data was extracted, and the quality of each study was assessed with four independent reviewers. Random effects models for significant heterogeneity and fixed effect models for homogeneous studies were conducted to estimate pooled effect sizes with 95% confidence intervals using Comprehensive Meta-Analysis version 3.3.070 and MetaXL version 2. Funnel plot and Higgins statistics were used to determine the heterogeneity of the included studies. Subgroup analyses were computed based on the types of pesticide exposure, study design, sample size category, and outcome assessment technique.
RESULT
A total of 38 articles with 118,303 children less than 18 years of age were included in this meta-analysis. Pesticide exposure among children increased the risk of asthma by 24%; (OR = 1.24, 95% CI: 1.14-1.35) with extreme heterogeneity ( = 81%, < 0.001). Exposure to pesticides increased the odds of developing wheezing among children by 34% (OR = 1.34, 95% CI: 1.14-1.57), with high heterogeneity ( = 79%, < 0.001) and also increased the risk of developing lower respiratory tract infection by 79% (OR = 1.79, 95% CI: 1.45-2.21) with nonsignificant low heterogeneity ( = 30%, -value = 0.18).
CONCLUSION
This meta-analysis provided valuable evidence supporting the association between childhood asthma, wheezing, and lower respiratory tract infection with pesticide exposure. The findings would contribute to a better understanding of the estimate of the effect of pesticide exposure on respiratory health in children and inform evidence-based preventive strategies and public health interventions.

Meta-Analysis
BACKGROUND
Esophageal cancer, a global health concern, impacts predominantly men, particularly in Eastern Asia. Lymph node metastasis (LNM) significantly influences prognosis, and current imaging methods exhibit limitations in accurate detection. The integration of radiomics, an artificial intelligence (AI) driven approach in medical imaging, offers a transformative potential. This meta-analysis evaluates existing evidence on the accuracy of radiomics models for predicting LNM in esophageal cancer.
METHODS
We conducted a systematic review following PRISMA 2020 guidelines, searching Embase, PubMed, and Web of Science for English-language studies up to November 16, 2023. Inclusion criteria focused on preoperatively diagnosed esophageal cancer patients with radiomics predicting LNM before treatment. Exclusion criteria were applied, including non-English studies and those lacking sufficient data or separate validation cohorts. Data extraction encompassed study characteristics and radiomics technical details. Quality assessment employed modified Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) and Radiomics Quality Score (RQS) tools. Statistical analysis involved random-effects models for pooled sensitivity, specificity, diagnostic odds ratio (DOR), and area under the curve (AUC). Heterogeneity and publication bias were assessed using Deek's test and funnel plots. Analysis was performed using Stata version 17.0 and meta-DiSc.
RESULTS
Out of 426 initially identified citations, nine studies met inclusion criteria, encompassing 719 patients. These retrospective studies utilized CT, PET, and MRI imaging modalities, predominantly conducted in China. Two studies employed deep learning-based radiomics. Quality assessment revealed acceptable QUADAS-2 scores. RQS scores ranged from 9 to 14, averaging 12.78. The diagnostic meta-analysis yielded a pooled sensitivity, specificity, and AUC of 0.72, 0.76, and 0.74, respectively, representing fair diagnostic performance. Meta-regression identified the use of combined models as a significant contributor to heterogeneity (p-value = 0.05). Other factors, such as sample size (> 75) and least absolute shrinkage and selection operator (LASSO) usage for feature extraction, showed potential influence but lacked statistical significance (0.05 < p-value < 0.10). Publication bias was not statistically significant.
CONCLUSION
Radiomics shows potential for predicting LNM in esophageal cancer, with a moderate diagnostic performance. Standardized approaches, ongoing research, and prospective validation studies are crucial for realizing its clinical applicability.

Review
BACKGROUND
Alcohol consumption has been associated with higher blood pressure and an increased risk of hypertension. However, the possible exposure thresholds and effect-modifiers are uncertain.
METHODS
We assessed the dose-response relationship between usual alcohol intake and hypertension incidence in nonexperimental cohort studies. After performing a systematic literature search through February 20, 2024, we retrieved 23 eligible studies. We computed risk ratios and 95% CI of hypertension incidence using a nonlinear meta-analytic model based on restricted cubic splines, to assess the dose-response association with alcohol consumption.
RESULTS
We observed a positive and almost linear association between alcohol intake and hypertension risk with risk ratios of 0.89 (0.84-0.94), 1.11 (1.07-1.15), 1.22 (1.14-1.30), and 1.33 (1.18-1.49) for 0, 24, 36 and 48 g/d, respectively, using 12 g alcohol/d as the reference value. In sex-specific analyses, the association was almost linear in men over the entire range of exposure but only observed above 12 g/d in women, although with a steeper association at high levels of consumption compared with men. The increased risk of hypertension above 12 to 24 g alcohol/d was similar in Western and Asian populations and considerably greater in Whites than in Blacks, mainly due to the positive association in women at moderate-to-high intake.
CONCLUSIONS
Overall, our results lend support to a causal association between alcohol consumption and risk of hypertension, especially above an alcohol intake of 12 g/d, and are consistent with recommendations to avoid or limit alcohol intake. Sex and ethnicity appear to be major effect-modifiers of such association.

Review
BACKGROUND
Anti-inflammatory agents have emerged as a potential new therapy for major depressive disorder (MDD). In this meta-analysis, our aim was to evaluate the antidepressant effect of anti-inflammatory agents and compare their efficacy.
METHODS
We conducted a comprehensive search across multiple databases, including PubMed, Embase, Web of Science, Cochrane Review, Cochrane Trial, and ClinicalTrials.gov, to identify eligible randomized clinical trials. The primary outcome measures of our meta-analysis were efficacy and acceptability, while the secondary outcome measures focused on remission rate and dropout rate due to adverse events. We used odds ratio (OR) and 95% confidence interval (95% CI) to present our results.
RESULTS
A total of 48 studies were included in our analysis. In terms of efficacy, anti-inflammatory agents demonstrated a significant antidepressant effect compared to placebo (OR = 2.04, 95% CI: 1.41-2.97, p = 0.0002). Subgroup analyses revealed that anti-inflammatory agents also exhibited significant antidepressant effects in the adjunctive therapy subgroup (OR = 2.17, 95% CI: 1.39-3.37, p = 0.0006) and in MDD patients without treatment-resistant depression subgroup (OR = 2.33, 95% CI: 1.53-3.54, p < 0.0001). Based on the surface under the cumulative ranking curve (SUCRA) value of network meta-analysis, nonsteroidal anti-inflammatory drugs (NSAIDs) (SUCRA value = 81.6) demonstrated the highest acceptability among the included anti-inflammatory agents.
CONCLUSION
In summary, our meta-analysis demonstrates that anti-inflammatory agents have significant antidepressant effects and are well-accepted. Furthermore, adjunctive therapy with anti-inflammatory agents proved effective in treating MDD. Among the evaluated anti-inflammatory agents, NSAIDs exhibited the highest acceptability, although its efficacy is comparable to placebo.

Meta-Analysis
BACKGROUND
To solve the problem of workplace bullying among nurses, it is necessary to review the effects of interventions and generalize the findings. We conducted a systematic literature review and meta-analysis to evaluate the effects of cognitive rehearsal programs on workplace bullying among hospital nurses.
METHODS
Data were collected from March 30 to April 11, 2021, and 11,048 journal articles published in South Korea and internationally were examined across eight databases. Nine articles were selected for inclusion in the systematic literature review; five of the nine studies were included in the meta-analysis. For randomized controlled trials, the risk of bias was evaluated, and for non-randomized controlled trials, the study quality was evaluated using the Risk of Bias for Non-randomized Studies version 2.0. Egger's regression test was performed to determine publication bias.
RESULTS
Of the nine articles selected for this study, two were randomized controlled trials and seven were non-randomized controlled trials. The I value was 18.9%, indicating non-significant heterogeneity. The overall effect size of the cognitive rehearsal programs was -0.40 (95% confidence interval: -0.604 to -0.196; Z = -3.85; p = .0001) in a random-effects model, indicating a large effect size with statistical significance.
CONCLUSIONS
Therefore, cognitive rehearsal programs that address workplace bullying among hospital nurses are effective. Health policymakers must implement cognitive rehearsal programs in a policy manner to address the problems of bullying in the workplace.

Meta-Analysis
The prevalence and risk of mortality associated with intradialytic hypertension among patients with end-stage kidney disease on haemodialysis: A systematic review and meta-analysis.
INTRODUCTION
Intradialytic hypertension (IDHTN) is a common but less frequently recognised complication of haemodialysis. However, it is associated with increased overall mortality in patients on haemodialysis. This systematic review and meta-analysis aimed to determine the prevalence of IDHTN and associated mortality risk in the global haemodialysis population.
METHOD
A systematic search of PubMed and EMBASE was undertaken to identify articles with relevant data published between 1990 and 2023. The pooled prevalence of IDHTN in the global haemodialysis population was determined using the DerSimonian-Laird random-effects meta-analysis. The pooled hazards ratio for mortality in patients with IDHTN was also computed from the studies that reported mortality among haemodialysis patients with IDHTN. The study protocol was registered with PROSPERO (CRD42023388278).
RESULTS
Thirty-two articles from 17 countries were included, with a pooled population of 127,080 hemodialysis patients (median age 55.1 years, 38.2% females). Most studies had medium methodological quality (53.1%, n = 17). The overall pooled prevalence of IDHTN was 26.6% [(95% CI 20.2-33.4%), n = 27 studies, I2 = 99.3%, p<0.001 for heterogeneity], with significant differences depending on the definition used. The pooled proportion of haemodialysis sessions with IDHTN was 19.9% [(95% 12.5-28.6%, n = 8 studies, I2 = 99.3%, p<0.001 for heterogeneity)] with significant differences across the different definition criteria. The p-value for the Begg test was 0.85. The median pre-dialysis blood pressure was not significantly associated with IDHTN. The pooled hazard ratio for mortality was 1.37 (95% CI 1.09-1.65), n = 5 studies, I2 = 13.7%, and p-value for heterogeneity = 0.33.
CONCLUSION
The prevalence of IDHTN is high and varies widely according to the definition used. A consensus definition of IDHTN is needed to promote uniformity in research and management. The increased mortality risk forecasted by IDHTN highlights the need for optimal blood pressure control in patients on hemodialysis.

Review
OBJECTIVE
The purpose of this study is to evaluate the efficacy of Vitamin A (VitA) as an adjuvant therapy for pediatric Pneumonia (MPP) through meta-analysis, and to investigate its impact on inflammation levels (IL-6, IL-10), in order to explore the role of VitA in pediatric MPP.
METHODS
Using a systematic literature search method, relevant research literature is searched, and RCT studies that meet the requirements are selected based on preset inclusion and exclusion criteria. Then, a quality evaluation was conducted on the included literature, and meta-analysis was used to calculate the combined effect values of mortality rate, hospital stay, lung rale disappearance time, cough duration, fever duration, IL-6 and IL-10 levels, and heterogeneity analysis was conducted. The levels of IL-6 and IL-10 represent the inflammatory levels in pediatric MPP patients, and exploring their changes has significant implications for the anti-inflammatory effect of treatment.
RESULTS
A total of 10 RCT studies were included, with a total sample size of 1,485, including 750 cases in the control group and 735 cases in the observation group. The meta-analysis results of this study showed that there was a significant difference in the total clinical efficacy of using VitA adjuvant therapy compared to the control group without VitA [OR = 3.07, 95%CI = (2.81, 4.27)], < 0.05. However, there was no significant difference in the adverse reaction rate between the use of VitA as an adjuvant therapy and the control without VitA [OR = 1.17, 95%CI = (0.61, 2.27)], > 0.05. At the same time, the hospitalization time [MSD = -0.86, 95% CI = (-1.61, -0.21)], lung rale disappearance time [MSD = -0.78, 95%CI = (-1.19,-0.51)], cough duration [MSD = -1.07, 95%CI = (-1.41, -0.71)], and fever duration [MSD = -0.47, 95%CI = (-0.72, -0.23)] using VitA as an adjuvant treatment were obviously lower. In addition, the meta-analysis outcomes also showed that the use of VitA adjuvant therapy can significantly reduce IL-6 [MSD = -1.07, 95%CI = (-1.81, -0.27)] and IL-10 [MSD = -0.13, 95%CI = (-0.31, 0.12)] levels. This indicates that the application of VitA in pediatric MPP also has the effect of reducing inflammatory response.
CONCLUSION
Based on the meta-analysis results, VitA adjuvant therapy can significantly improve the clinical symptoms of pediatric MPP patients, shorten hospitalization time, promote the disappearance of lung rales, and alleviate cough and fever symptoms. In addition, VitA adjuvant therapy can effectively reduce inflammation levels, indicating its potential role in inhibiting inflammatory responses. In clinical practice, VitA adjuvant therapy for pediatric MPP can be promoted as a potential treatment option.

Cardiovascular Outcomes of Sodium-Glucose Cotransporter-2 Inhibitors Therapy in Patients with Type 2 Diabetes Mellitus and Chronic Kidney Disease: A Systematic Review and Updated Meta-Analysis.
BACKGROUND AND OBJECTIVES
The efficacy of sodium-glucose cotransporter-2 inhibitors (SGLT2i) may depend on renal function, and this raises theoretical concern over its effects on cardiovascular outcomes in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD).
METHODS
This systematic review and updated meta-analysis of randomized controlled trials (RCTs) compared cardiovascular outcomes of patients with T2DM and CKD treated with SGLT2i to placebo. PubMed, Embase, and Cochrane were systematically searched. Prespecified subgroup analyses were performed in strata of estimated glomerular filtration rate (eGFR) of <45 mL/min/1.73 m² and 45 to 59 mL/min/1.73 m².
RESULTS
Nine RCTs comprising 29,146 patients were selected. Average follow-up ranged from 0.75 to 4.2 years. SGLT2i were shown to reduce the risk of all-cause mortality (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.79-0.97; p=0.01), the composite of cardiovascular mortality or hospitalizations for heart failure (HHF: HR, 0.71; 95% CI, 0.65-0.78; p<0.001), cardiovascular mortality (HR, 0.86; 95% CI, 0.76-0.98; p=0.02), HHF (HR, 0.62; 95% CI, 0.55-0.71; p<0.001), major adverse cardiovascular events (HR, 0.85; 95% CI, 0.77-0.94; p=0.002), stroke (HR, 0.76; 95% CI, 0.59-0.97; p=0.03), and myocardial infarction (HR, 0.78; 95% CI, 0.67-0.91; p=0.001). These findings were consistent over strata of eGFR, albeit with a lower incidence of stroke in patients treated with SGLT2i with eGFR <45 mL/min/1.73 m² (p-value for interaction=0.04).
CONCLUSIONS
Compared with a placebo, patients with T2DM and CKD treated with SGLT2i experience a reduction in all-cause mortality, cardiovascular mortality, and HHF.

Meta-Analysis
OBJECTIVE
Periimplantitis (PI) is a complex multifactorial chronic disease caused by interactions between bacteria, host immune-inflammatory responses, and genetic or environmental factors that modify buccal eutrophism. In daily clinical practice, an increase in the prevalence of PI (8%) determined the need to establish the PI causes and set optimal therapeutic strategies. The interleukin family (IL-1), a group of cytokines, triggers and perpetuates peri-implantitis. Therefore, they could be used as biomarkers for diagnosis and treatment. This systematic review aimed to analyze the correlation between IL-1 allelic polymorphism (IL-1A -889, IL-1β -511, IL-1β +3954) and the PI disease.
MATERIALS AND METHODS
Selected databases were PubMed, Scopus, and Cochrane Library. The search strategy included the following terms: "dental implants"; "periimplantitis"; "interleukin-IL-1"; "polymorphism"; "perimplant bone loss". Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A meta-analysis was conducted on five of 40 review articles. p-values, confidence intervals (CI), and Odds ratios (OR) were assessed. In 4 articles, the p-value was lower than 0.05, confirming the statistical significance of the result.
RESULTS
The prevalence of the selected studies reported the existence of a causal association between polymorphisms of IL-1 and the onset of peri-implantitis, especially for IL-1 allelic variants associated with further polymorphic genes encoding for IL-6, tumor necrosis factor-alpha (TNF-α), matrix metalloproteinases (MMP)-8, IL-1Na, IL-8, IL-18, osteopontin (OPN). In addition, the presence of the IL-1 polymorphism and PI is particularly higher in smokers, diabetes, and autoimmune disease patients.
CONCLUSIONS
The detection of salivary biomarkers is, therefore, a diagnostic tool with a high potential to intercept the PI early and act with appropriate and non-invasive treatment. Due to the continued technological innovation in biomarkers and diagnostic sciences, further studies are needed to investigate the role of these biochemical mediators. The results of studies and the recent technological innovation in biomarkers and diagnostic sciences will allow further research to investigate the role of these biochemical mediators.

Review
Cervical intervertebral disc herniation is a common condition and most often presents as neck or upper limb pain causing varying levels of disability and dysfunction. Percutaneous injection of ozone into the intradiscal space is a novel and minimally invasive technique for managing this condition and can be an effective alternative to surgical management. A literature search was done using the keywords ozone disc nucleolysis of cervical intervertebral lesions, and five studies were selected based on the inclusion and exclusion criteria. Meta-analysis was performed to determine safety, effectiveness, and symptomatic relief (determined based on the visual analog scale (VAS)) with the publication bias being removed. Subjects treated with ozone therapy showed significant reduction (p < 0.0001) in VAS score as compared to baseline VAS score with a standardized mean difference of 2.78 (95% CI = 1.48 to 4.07; Z value = 4.20). Ozone nucleolysis is a minimally invasive, relatively safe, and optimally effective treatment option for reducing the pain related to cervical disc. Intradiscal ozone therapy can be considered an alternative treatment modality, and well-designed, randomized clinical trials are required to confirm the long-term superiority of ozone therapy against other treatment modalities available for cervical disc herniation.
