Review
Bertoni, a no-calorie natural sweetener, contains a plethora of polyphenols that exert antioxidant properties with potential medicinal significance. Due to the variety of functional groups, polyphenols exhibit varying solubility depending on the nature of the extraction solvents (water, organic, or their mixtures, defined further on as hydroalcoholic extracts). In the present study, we performed a systematic review, following PRISMA guidelines, and meta-analysis, synthesizing all available data from 45 articles encompassing 250 different studies. Our results showed that the total phenolic content (TPC) of hydroalcoholic and aqueous extracts presents higher values (64.77 and 63.73 mg GAE/g) compared to organic extracts (33.39). Total flavonoid content (TFC) was also higher in aqueous and hydroalcoholic extracts; meta-regression analysis revealed that outcomes in different measuring units (mg QE/g, mg CE/g, and mg RUE/g) do not present statistically significant differences and can be synthesized in meta-analysis. Using meta-regression analysis, we showed that outcomes from the chemical-based ABTS, FRAP, and ORAC antioxidant assays for the same extract type can be combined in meta-analysis because they do not differ statistically significantly. Meta-analysis of ABTS, FRAP, and ORAC assays outcomes revealed that the antioxidant activity profile of various extract types follows that of their phenolic and flavonoid content. Using regression meta-analysis, we also presented that outcomes from SOD, CAT, and POX enzymatic antioxidant assays are independent of the assay type (-value = 0.905) and can be combined. Our study constitutes the first effort to quantitatively and statistically synthesize the research results of individual studies using all methods measuring the antioxidant activity of stevia leaf extracts. Our results, in light of evidence-based practice, uncover the need for a broadly accepted, unified, methodological strategy to perform antioxidant tests, and offer documentation that the use of ethanol:water 1:1 mixtures or pure water can more efficiently extract stevia antioxidant compounds.

Meta-Analysis
BACKGROUND
Undernutrition increases the risk of TB infection to be active TB, death and relapse of the disease. Undernutrition also disturbs the management process of tuberculosis. Therefore, this study aimed to estimate the pooled magnitude and determinants of undernutrition among TB patients in Ethiopia.
METHODS
From August 20, 2022 to January 6, 2023, the research articles were identified via the search engines Google Scholar, Medline, Pub Med, Cochrane Library, and Web of Science. Stata version 14 was used for analysis, along with a standardized data extraction checklist. The Cochrane Q test statistic and I2 statistics were used to determine heterogeneity. A random-effect model was used to assess the extent of undernutrition among TB patients. OR with a 95% CI was used to report the relationship between undernutrition and independent factors. A funnel plot and Egger's test were used to examine publication bias.
RESULTS
A total of 720 research articles were identified via several databases and 21 studies were included in the systematic review and meta-analysis. The pooled magnitude of undernutrition among TB patients was 48.23% (95% CI 42.84, 53.62). The current meta-analysis revealed that patients who had no formal education (OR = 2.11(95%CI: 1.09, 4.06), average monthly income < 1800 ETB (OR = 2.32 (95CI: 1.33, 4.04), unable to work (OR = 2.61(95CI:1.99, 3.43), patients who had eating disorder (OR = 2.73 (95CI: 2.09, 3.56), patients who had intestinal parasite (OR = 3.77 (95CI: 2.39, 5.94), patients of > 5 family size (OR = 3.79 (95CI: 1.06, 14.93), and patients who drank alcohol (OR = 1.47(95CI: 1.06, 2.05) were significantly associated with undernutrition.
CONCLUSION
This meta-analysis examined the high magnitude of undernutrition among TB patients in Ethiopia. Strategic and police-oriented intervention to prevent factors contributing to the problem is mandatory.

Journal of Cardiothoracic Surgery Jun 2024Systematic evaluation of the safety of del Nido cardioplegia compared to cold blood cardioplegia in adult cardiac surgery. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
Systematic evaluation of the safety of del Nido cardioplegia compared to cold blood cardioplegia in adult cardiac surgery.
METHODS
We systematically searched PubMed, EMbase, The Cochrane Library and ClinicalTrials.gov for randomized clinical trials (published by 14 January 2024) comparing del Nido cardioplegia to cold blood cardioplegia in adult. Our main endpoints were myocardial injury markers and clinical outcomes. We assessed pooled data by use of a random-effects model or a fixed-effects model.
RESULTS
A total of 10 studies were identified, incorporating 889 patients who received del Nido cardioplegia and 907 patients who received cold blood cardioplegia. The meta-analysis results showed that compared with the cold blood cardioplegia, the del Nido cardioplegia had less volume of cardioplegia, higher rate of spontaneous rhythm recovery after cross clamp release, lower levels of postoperative cardiac troponin T and creatinine kinase-myocardial band, all of which were statistically significant. However, there was no statistically significant difference in postoperative troponin I and postoperative left ventricular ejection fraction. The clinical outcomes including mechanical ventilation time, intensive care unit stay time, hospital stay time, postoperative stroke, postoperative new-onset atrial fibrillation, postoperative heart failure requiring intra-aortic balloon pump mechanical circulation support, and in-hospital mortality of both are comparable.
CONCLUSION
Existing evidence suggests that del Nido cardioplegia reduced volume of cardioplegia administration and attempts of defibrillation. The superior postoperative results in CTnT and CK-MB may provide a direction for further research on improvement of the composition of cardioplegia.

Meta-Analysis
INTRODUCTION
Cigarette smoking is a persistent public health problem as it is a risk factor for many diseases. Previous studies on the role of illegal drug use in cigarette smoking have yielded disparate and inconclusive results, hindering the development of effective intervention strategies to address this issue. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence of cigarette smoking and its associated factors, with a specific focus on the influence of illegal drug use among students in Ethiopia.
METHODS
We conducted a comprehensive search of international databases, including PubMed, Cochrane Library, Science Direct, CINAHL, African Journals Online, HINARI, Global Health, and Google and Google Scholar. Grey literature was also identified from various university digital libraries. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA) guidelines. Due to the high heterogeneity among the included studies (I2 = 98.6%; p-value <0.001), we employed a random-effects model with a 95% confidence interval (CI) to estimate the pooled effect using STATA 14 software. The publication bias was assessed using a statistical Egger regression test.
RESULTS
A total of 22 studies involving 18,144 students met the eligibility criteria for this systematic review and meta-analysis. The pooled prevalence of lifetime and current cigarette smoking among students in Ethiopia was 13.8% (95% CI: 9.90-17.82) and 9.61% (95% CI: 7.19-12.03), respectively. Students who used illegal drugs were twenty-three times more likely to smoke cigarettes compared to their counterparts (OR = 23.57, 95% CI: 10.87-51.1). Living in urban settings (OR = 2.9; 95% CI: 1.15-7.28) and the habit of alcohol consumption (OR = 4.79; 95% CI: 1.57-14.64) were also identified as factors associated with cigarette smoking.
CONCLUSIONS
We found that more than one in eight students in Ethiopia have engaged in lifetime cigarette smoking. Notably, students who used illegal drugs exhibited a significantly higher likelihood of cigarette smoking. In light of these findings, it is imperative to implement comprehensive public health interventions that target illegal drug use, cigarette smoking, and alcohol consumption, with a particular emphasis on urban residents.

Meta-Analysis Review
Palmitoylethanolamide (PEA) emerged over the years as a promising approach in the management of chronic pain. Despite the fact that the efficacy of micron-size PEA formulations appears to be time-dependent, the optimal timing has not yet been elucidated. This systematic review and meta-analysis aim to estimate the possible advantage of an extended treatment in the relief of chronic pain. The literature search was conducted consulting scientific databases, to identify clinical trials in which micron-size PEA was administered for at least 60 days, and pain assessed by the Visual Analogue Scale (VAS) or Numeric Rating Scale (NRS). Nine studies matched the required criteria, for a total of 742 patients involved. The meta-analysis showed a statistically and clinically significant pain intensity reduction after 60 days of micron-size PEA supplementation, compared to 30 days (1.36 points, < 0.01). The secondary analysis revealed a weighted NRS/VAS score decrease of 2.08 points within the first month of treatment. These two obtained scores corresponded to a 35.1% pain intensity reduction within the first month, followed by a further 35.4% during the second month. Overall, these results confirm the clinically relevant and time-depended pain-relieving effect of micron-size PEA and therefore the advantage of an extended treatment, especially in patient with incomplete pain management.

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
To provide a comprehensive review of nonsurgical approaches for the management of Warthin's tumors (WTs) and evaluate their safety and efficacy as alternatives to surgical intervention. A systematic literature search was conducted in PubMed, Web of Science, Cochrane Library, and Embase databases using specific keywords related to WT and nonsurgical treatments. Studies published before 2012, non-English publications, and mixed methodology articles were excluded. The selection process involved title and abstract screening, followed by a thorough assessment of the remaining articles based on inclusion and exclusion criteria. Data regarding study characteristics, participants, interventions, and outcomes were collected. A total of 1582 records were analyzed, and 6 studies met the inclusion criteria. These studies evaluated different nonsurgical interventions for WT management, including microwave ablation, radiofrequency ablation, and ultrasound-guided ethanol sclerotherapy. The findings demonstrated that microwave ablation and radiofrequency ablation led to a significant reduction in tumor size and improved cosmetic appearance. Ultrasound-guided ethanol sclerotherapy also resulted in a notable decrease in tumor size without complications. The included studies supported the safety and efficacy of these nonsurgical options for the treatment of WTs. Nonsurgical approaches, such as microwave ablation, radiofrequency ablation, and ultrasound-guided ethanol sclerotherapy, have emerged as viable alternatives to surgical intervention for the management of WTs. These interventions offer promising outcomes in terms of tumor size reduction and cosmetic improvement. Further research with larger sample sizes and long-term follow-up is warranted to validate these findings and establish standardized protocols for nonsurgical management of WTs.

Meta-Analysis Review
BACKGROUND
Alcohol consumption is a major risk factor for cancer, and when combined with smoking, the risk increases. Nevertheless, few studies have comprehensively evaluated the combined effects of alcohol consumption and smoking on the risk of various cancer types. Therefore, to assess these effects, we conducted a systematic review and meta-analysis.
METHODS
We performed a systematic search of five literature databases, focusing on cohort and case-control studies. Considering exposure levels, we quantified the combined effects of alcohol consumption and smoking on cancer risk and assessed multiplicative interaction effects.
RESULTS
Of 4,452 studies identified, 24 (4 cohort studies and 20 case-control studies) were included in the meta-analysis. We detected interaction effect of light alcohol and moderate smoking on head and neck cancer risk (relative risk [RR], 4.26; 95% confidence interval [CI], 2.50-7.26; ² = 65%). A synergistic interaction was observed in heavy alcohol and heavy smoking group (RR, 35.24; 95% CI, 23.17-53.58; ² = 69%). In more detailed cancer types, the interaction effect of heavy alcohol and heavy smoking was noticeable on oral (RR, 36.42; 95% CI, 24.62-53.87; ² = 46%) and laryngeal (RR, 38.75; 95% CI, 19.25-78.01; ² = 69%) cancer risk.
CONCLUSION
Our study provided a comprehensive summary of the combined effects of alcohol consumption and smoking on cancers. As their consumption increased, the synergy effect became more pronounced, and the synergy effect was evident especially for head and neck cancer. These findings provide additional evidence for the combined effect of alcohol and smoking in alcohol guidelines for cancer prevention.

We conducted a systematic review to explore the relationship between perceived risk for HIV acquisition and sexual HIV exposure among sexual and gender minorities. We included 39 studies divided into (i) correlations or associations, (ii) models using sexual HIV exposure as the outcome, and (iii) models using perceived risk for HIV acquisition as the outcome. The sample size range was from 55 to 16,667 participants, primarily cisgender men who have sex with men (73.3%) and White (51.3%). Sexual HIV exposure and perceived risk for HIV acquisition assessments and recall time frames across studies differed markedly. Most of studies (84.6%) found significant correlations, comparisons, or associations between different levels of perceived risk for HIV acquisition and high sexual HIV exposure. In addition, 51.3% of studies reported other variables associated with high sexual HIV exposure (i.e., misuse of substances or alcohol) or with high perceived risk for HIV acquisition (i.e., younger age). In conclusion, the association between perceived risk for HIV acquisition and sexual HIV exposure has shown to be consistent. However, the assessment for perceived risk for HIV acquisition should include more components of perception (i.e., an affective component), or for sexual HIV exposure should consider the different estimated sexual per-acts probability of acquiring HIV.

Efficacy and safety of isosorbide mononitrate plus misoprostol compared to misoprostol alone in the management of the first and second trimester abortion: a systematic review and meta-analysis.
BACKGROUND
However, misoprostol is often used to terminate a pregnancy, but it can also cause side effects. Isosorbide mononitrate (ISMN) can help the cervix mature by increasing the production of prostaglandin E2 and vasodilation. Considering that the results of studies in this field are contradictory, it is the purpose of this study to evaluate the efficacy and safety of vaginal ISMN plus misoprostol compared to misoprostol alone in the management of first- and second-trimester abortions.
METHOD
The search process was conducted for MEDLINE through the PubMed interface, Scopus, Web-of-Science, Science Direct, the Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform until November 10, 2023. Our assessment of bias was based on version 2 of the risk-of-bias tool (RoB2) for randomized trials and our level of evidence quality was determined by GRADE. Meta-analysis of all data was carried out using Review Manager (RevMan) version 5.1.
RESULT
Seven randomized clinical trials were included in the systematic review and three in the meta-analysis, with mixed quality. The results of the meta-analysis revealed that in the second-trimester abortion, the inclusion of ISMN in conjunction with vaginal misoprostol results in a noteworthy reduction in the induction abortion interval, specifically by 4.21 h (95% CI: -7.45 to -0.97, P = 0.01). The addition of vaginal ISMN to misoprostol, compared to vaginal misoprostol alone, increased the odds of a completed abortion by 3.76 times. (95% CI: 1.08 to 13.15, P = 0.04).
CONCLUSION
The findings of this study can offer valuable insights aimed at enhancing counseling and support for non-surgical methods of medication abortion within professional settings. Moreover, it improves the effectiveness of clinical treatment and reduces the occurrence of unnecessary surgical interventions in the abortion management protocol.
