The efficacy of compression dressings to reduce haematoma post cardiac implantable electronic devices - a systematic review and meta-analysis

Abstract Background Pocket haematomas are one of the most common complications post cardiovascular implantable electronic device (CIED) implantation. Objective We explored the use of mechanical compression devices compared to the conventional dressings post CIED implantation, to reduce the incidence of pocket haematomas. Secondary outcomes were pain scores and wound scar or healing. Methods Five electronic databases were systematically searched from their inception to 1st November 2023, identifying all studies which explored compression dressings post CIED implantation. Data were independently extracted by investigators according to predefined clinical endpoints. We used a Random-effects model for data analysis based on event rates (ER) and 95% confidence interval (CI). Results Six studies (786 patients) were included in the meta-analysis, with 373 in the compression arm and 385 patients in the control groups across the studies. There was a total incidence of 82 haematomas, of which 24.4% were in the mechanical compression group and 75.6% in the conventional dressings group (RR 0.36, 95% CI 0.23- 0.57). One study suggested improved wound healing with the compression dressing arm (Manchester Scar Scale 9.5 at 2 weeks for the control group and 7.5 for the compression dressings group). Two studies suggested increased pain scores (using a visual analogue scale) shortly after dressing application. One study suggested improved comfort scores in the compression group compared to the control at 48 hours and 7 days. Conclusion This systematic review and meta-analysis suggests for patients post CIED implantation, the use of novel mechanical compression dressings, when compared to conventional dressings, reduces the risk of pocket haematoma.Forest plot

Gut microbiome alterations during gastric cancer: evidence assessment of case–control studies

ObjectivesThe study aims to systematically identify the alterations in gut microbiota that observed in gastric cancer through comprehensive assessment of case–control studies.MethodsThe systematic literature search of PubMed, Embase, Cochrane Library, and Web of Science was conducted to identify case–control studies that compared the microbiomes of individuals with and without gastric cancer. Quality of included studies was evaluated with the Newcastle-Ottawa Quality Assessment Scale (NOS). Meta-analyses utilized a random-effects model, and subgroup and sensitivity analyses were performed to assess study heterogeneity. All data analyses were performed using the “metan” package in Stata 17.0, and the results were described using log odds ratios (log ORs) with 95% confidence intervals (CIs).ResultsA total of 33 studies involving 4,829 participants were eligible for analysis with 29 studies provided changes in α diversity and 18 studies reported β diversity. Meta-analysis showed that only the Shannon index demonstrated statistical significance for α-diversity [−5.078 (−9.470, −0.686)]. No significant differences were observed at the phylum level, while 11 bacteria at genus-level were identified significant changed, e.g., increasing in Lactobacillus [5.474, (0.949, 9.999)] and Streptococcus [5.095, (0.293, 9.897)] and decreasing in Porphyromonas and Rothia with the same [−8.602, (−11.396, −5.808)]. Sensitivity analysis indicated that the changes of 9 bacterial genus were robust. Subgroup analyses on countries revealed an increasing abundance of Helicobacter and Streptococcus in Koreans with gastric cancer, whereas those with gastric cancer from Portugal had a reduced Neisseria. Regarding the sample sources, the study observed an increase in Lactobacillus and Bacteroides in the gastric mucosa of people with gastric cancer, alongside Helicobacter and Streptococcus. However, the relative abundance of Bacteroides decreased compared to the non-gastric cancer group, which was indicated in fecal samples.ConclusionThis study identified robust changes of 9 bacterial genus in people with gastric cancer, which were country-/sample source-specific. Large-scale studies are needed to explore the mechanisms underlying these changes.Systematic ReviewUnique Identifier: CRD42023437426 https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023437426.

Immunogenicity of Recombinant Zoster Vaccine: A Systematic Review, Meta-Analysis, and Meta-Regression.

The adjuvanted recombinant zoster vaccine (RZV), consisting of varicella-zoster virus glycoprotein E (gE) and the AS01B adjuvant system, effectively prevents herpes zoster (HZ). In the absence of a well-defined correlate of protection, it is important to monitor the RZV immune response, as a proxy of clinical effectiveness. This systematic review examined post-vaccination parameters: humoral and cell-mediated immunity, avidity index, geometric mean concentration of antibody (GMC), and immunity persistence. The meta-analysis used a random-effects model, and subgroup and meta-regression analyses were conducted. Among 37 included articles, after one month from RZV-dose 2, the pooled response rate for anti-gE humoral immunity was 95.2% (95%CI 91.9-97.2), dropping to 77.6% (95%CI 64.7-86.8) during immunosuppression. The anti-gE cell-mediated immunity-specific response reached 84.6% (95%CI 75.2-90.9). Varying factors, such as age, sex, coadministration with other vaccines, prior HZ, or live-attenuated zoster vaccine, did not significantly affect response rates. RZV induced a substantial increase in gE avidity. Immunity persistence was confirmed, with more rapid waning in the very elderly. This systematic review indicates that RZV elicits robust immunogenicity and overcomes immunocompromising conditions. The findings underscore the need for further research, particularly on long-term immunity, and have the potential to support HZ vaccination policies and programs.

Staged versus immediate complete vessel revascularization in patients presenting with ST-segment elevation myocardial infarction: a systematic review and meta-analysis

Abstract Funding Acknowledgements None. Introduction In patients presenting with acute coronary syndrome (ACS) ST-segment elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) is the preferred modality of reperfusion. However, these patients may also have multivessel coronary artery disease (CAD) on coronary angiography which is associated with higher risk of mortality. Current guidelines recommend complete revascularization in STEMI with multivessel CAD, however this poses a high risk for major acute cardiovascular events (MACE). Other available reperfusion strategies include staged vessel revascularization. This meta-analysis aims to determine if staged vessel revascularization can be a better mode of reperfusion strategy in patients with STEMI with multivessel CAD. Methods A comprehensive search of randomized controlled trials (RCT) was conducted with the use of staged versus immediate complete vessel revascularization in patients with STEMI. Outcome measures to assess the effectiveness of these techniques were all-cause mortality, MACE and target vessel revascularization. The analyses were done using random effects analysis model by mantel-haenszel statistical method via Review Manager V5.4. Results There were five studies included in the meta-analysis with 1,483 subjects analyzed. There was 26% less risk of all-cause mortality (RR 0.74 [95% CI: 0.41-1.31]) and 6% less risk for MACE (RR 0.94 [95% CI: 0.58-1.52]) in staged revascularization compared to immediate complete revascularization. In terms of target-vessel revascularization there was no statistical difference between the two treatment strategies (RR 1.02 [95% CI: 0.57-1.83]). Conclusion Staged and immediate complete vessel revascularization have similar rates of target-vessel revascularization among patients presenting with STEMI. However, staged vessel revascularization showed lower rates of all-cause mortality and MACE, which suggest that this treatment strategy may be a preferable type of revascularization in patients presenting with STEMI with multivessel CAD.

The effects of weight loss interventions on children and adolescents with non-alcoholic fatty liver disease: A systematic review and meta-analysis.

Overall, there is conflicting evidence regarding the beneficial effects of optimal lifestyle modification, particularly weight loss interventions, with nonalcoholic fatty liver disease (non-alcoholic fatty liver disease (NAFLD)). Therefore, this study investigated the effects of weight loss interventions on laboratory and clinical parameters in children and adolescents with NAFLD. Original databases (PubMed/MEDLINE, Web of Science, SCOPUS, and Embase) were searched using standard keywords to identify all controlled trials investigating the effects of weight loss interventions among NAFLD children and adolescents. Pooled weighted mean difference and 95% confidence intervals were achieved by random-effects model analysis. Eighteen eligible clinical trials were included in this systematic review and meta-analysis. The pooled findings showed that especially more intense weight loss interventions significantly reduced the glucose (p=0.007), insulin (p=0.002), homeostatic model assessment-insulin resistance (HOMA-IR) (p=0.003), weight (p=0.025), body mass index (BMI) (p=0.003), BMI z-score (p<0.001), waist circumference (WC) (p=0.013), triglyceride (TG) (p=0.001), and aspartate transaminase (AST) (p=0.027). However, no significant changes were found in total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine transaminase (ALT), and hepatic steatosis grades (all p>0.05) following weight loss interventions. Weight loss interventions had significant effects on NAFLD-related parameters including glucose, insulin, HOMA-IR, weight, BMI, BMI z-score, WC, TG, and AST.

The effects of bupropion alone and combined with naltrexone on weight loss: a systematic review and meta-regression analysis of randomized controlled trials

BackgroundThe global prevalence of obesity and overweight is a significant concern in the field of public health. However, addressing and combating these conditions pose considerable challenges. Numerous interventional studies have been conducted to assess the possible impact of bupropion on weight reduction. The primary objective of this study was to conduct a comprehensive investigation into the effects of bupropiona alone and in combination with naltrexone on weight, body mass index (BMI), and waist circumferences (WC).MethodsA systematic search was conducted in five databases using established keywords. The purpose of this search was to uncover controlled trials that examined the impact of bupropion, either as a standalone intervention or in combination with naltrexone, on weight loss outcomes. The random-effects model analysis was used to provide pooled weighted mean difference and 95% confidence intervals.ResultsTwenty five studies with 22,165 participants’ were included in this article. The pooled findings showed that bupropion administration has an effect on lowering weight (WMD: -3.67 kg, 95% CI: -4.43 to -2.93) and WC (WMD: -2.98 cm, 95% CI -3.78 to -2.19) in compared with control groups. The analysis also showed that the effects of the present intervention on weight and WC during the intervention are > 26 weeks and ≤ 26 weeks compared to the other group, respectively. In addition, changes in weight loss and WC after receiving bupropion together with naltrexone were more compared to bupropion alone.ConclusionsIn conclusion, the addition of combination therapies like bupropion and naltrexone to lifestyle modifications including diet would cause significant weight loss.

Cost-comparison of robotic versus laparoscopic colorectal resections: a mapped systematic review and meta-analysis of published studies.

Robotic colorectal resections (RCR) have been gaining popularity recently due to several advantages in addition to oncological safety. The objective of this review is to evaluate the cost comparison of RCR versus laparoscopic colorectal resections (LCR). All types of comparative studies reporting the cost of RCR versus LCR were retrieved from the search of standard medical electronic databases and analysis was conducted by using the principles of meta-analysis on the statistical software RevMan version 5. The search of medical databases yielded 13 studies (one randomised trial and 12 comparative studies) on 16,082 patients undergoing oncological and non-oncological colorectal resections. Eleven studies reported total cost whereas seven studies reported only operative cost. In the random effects model analysis, LCR was associated with the reduced total cost [standardised mean difference -62.34, 95% confidence interval (CI): -75.14 to -49.54, Z=9.55, P<0.001] as well as reduced operative cost (standardised mean difference -4.60, 95% CI: -5.90 to -3.31, Z=6.96, P<0.001) compared to RCR. However, there was significant heterogeneity [Tau2=346.74, Chi2=29,559.11, df =11 (P<0.001; I2=100%); Tau2=2.73, Chi2=832.21, df =6 (P<0.001; I2=99%)] among included studies. The LCR seems to be more economical as compared to the RCR in terms of operative cost as well as total cost (operative plus in-patient stay). However, due to statistically significant heterogeneity among included studies and paucity of the randomised trials, these findings should be taken cautiously.

Effect of metformin on anti-mullerian hormone levels in women with polycystic ovarian syndrome: a systematic review and meta-regression analysis of randomized controlled trials with

BackgroundSeveral interventional studies have evaluated the potential anti-Mullerian hormone (AMH)-reduction effect of metformin. However, the results are still contradictory. In order to obtain a better viewpoint from them, this study aimed to comprehensively investigate the effects of metformin on AMH in the women with with polycystic ovarian syndrome (PCOS).MethodsScopus, PubMed/Medline, Web of Science, Cochrane, and Embase databases were searched using standard keywords to identify all controlled trials investigating the AMH levels following metformin administration. Pooled weighted mean difference and 95% confidence intervals were achieved by random-effects model analysis for the best estimation of outcomes.ResultsSixteen studies with 484 participants’ were included in this article. The pooled findings showed that AMH levels in the single arm clinical trials were significantly reduced (pooled WMD of -3.06 ng/ml; 95% confidence interval [CI] -4.03 to -2.10; P < 0.001) after use of metformin. Furthermore, compared to the control group, in randomized clinical trials, a reduced significant effect on AMH levels was observed following use of metformin (pooled WMD of -3.47 ng/ml; 95% CI -7.14 to -0.19; P = 0.047). Furthermore, higher reduction in the AMH levels with a metformin dosage ≤ 1500 mg/day and duration of treatment ≤ 12 weeks when compared to higher dosages and duration of intervention, observed in this meta-analysis.ConclusionsIn conclusion, results this meta-analysis of clinical trials confirms the beneficial effect of the treatment with metformin in the reduction of the AMH levels in women.

Prevalence of physical violence against people in insecure migration status: A systematic review and meta-analysis.

This study summarised evidence on the prevalence of interpersonal, community and state physical violence against people in insecure migration status. We conducted a systematic review and meta-analysis of primary studies that estimated prevalence of physical violence against a population in insecure migration status. We searched Embase, Social Policy and Practice, Political Science Complete, SocINDEX and Web of Science Social Sciences Citation Index for reports published from January 2000 until 31 May 2023. Study quality was assessed using an adapted version of the Joanna Briggs assessment tool for cross-sectional studies. Two reviewers carried out screening, data extraction, quality assessment and analysis. Meta-analysis was conducted in Stata 17, using a random effects model and several exploratory subgroup analyses. We retrieved 999 reports and included 31 retrospective cross-sectional studies with 25,997 migrants in insecure status. The prevalence estimate of physical violence was 31.16% (95% CI 25.62-36.70, p < .00). There was no statistically significant difference in the estimates for prevalence of violence for men (35.30%, 95% CI 18.45-52.15, p < .00) and for women (27.78%, 95% CI 21.42-34.15, p < .00). The highest point estimate of prevalence of violence was where insecure status was related to employment (44.40%, 95% CI 18.24-70.57, p < .00), although there were no statistically significant difference in the subgroup analysis. The prevalence of violence for people in undocumented status was not significantly different (29.13%, 95% CI 19.86-38.41, p < .00) than that for refugees and asylum seekers (33.29%, 95% CI 20.99-45.59, p < .00). The prevalence of violence in Asia was 56.01% (95% CI 22.47-89.55, p < .00). Europe had the lowest point prevalence estimate (17.98%, 95% CI 7.36-28.61, p < .00), although the difference was not statistically significant. The prevalence estimate during the migration journey was 32.93% (95% CI 24.98-40.88, p < .00). Intimate partner violence attached to insecure status was estimated at 29.10%, (95% CI 8.37-49.84, p = .01), and state violence at 9.19% (95% CI 6.71-11.68, p < .00). The prevalence of physical violence is a concern among people in a range of insecure migration statuses. Prevalence of violence is not meaningfully higher for people in undocumented status than for people in other types of insecure status. PROSPERO (CRD42021268772).

Blood pressure targets after successful reperfusion in mechanical thrombectomy for acute ischemic stroke: an updated systematic review and meta-analysis of randomized clinical trials.

This study sought to determine whether intensive blood pressure (BP) control for patients with successful reperfusion following acute ischemic stroke (AIS) is beneficial, compared to conventional BP management. PubMed, Embase, and Cochrane databases were systematically searched for randomized controlled trials (RCTs) on the subject. The studied outcomes included dependency or death at 90days (modified Rankin Scale [mRS] 3-6); severe disability at 90days (mRS 3-5); mortality at 90days; and symptomatic intracranial hemorrhage. Odds ratios (OR) with 95% confidence intervals were used to compare the treatment effects for categorical outcomes. We employed a fixed-effect model for analyses with low heterogeneity (I2 < 25%) and a random-effects model for analyses with higher heterogeneity. A total of 1519 patients were included, with 50% (n = 760) receiving intensive BP control (systolic BP < 140mmHg). Functional disability or death at 90days was significantly higher in the intensive group (54.9%) compared to the conventional treatment group (44.1%) (OR = 1.51; 95% Confidence Interval [CI]: 1.15-1.96; p = 0.003; I2 = 29%). Severe functional disability (mRS 3-5) was significantly higher in the intensive group (30.6% vs. 43.5%, OR = 1.75; 95%CI = 1.36-2.25; p < 0.0001; I2 = 0%). There was no difference in symptomatic intracranial hemorrhage (OR = 1.13; 95%CI = 0.76-1.67) or mortality (OR = 1.22; 95%CI = 0.9-1.64). Intensive BP control is harmful in patients who underwent EVT for AIS and achieved successful reperfusion. It yields higher rates of functional dependence, with no differences in mortality or symptomatic intracranial hemorrhage.

Estimate the burden of malnutrition among children with cerebral palsy in Sub-Saharan Africa: a systematic review with meta-analysis.

Malnutrition is more prevalent among children with cerebral palsy and a major factor for child morbidity and mortality in children with different co-morbidity, especially in Sub-Saharan Africa: The main aim of this systematic review and meta-analysis was to estimate the burden of malnutrition among children with cerebral palsy in Sub-Saharan Africa. We searched PubMed, Web of Science, Google Scholar, Research Gate, and institutional repositories for papers that reported the proportion of malnutrition among children with cerebral palsy that were published between December 2010 and September 2023. Data were retrieved using the standardized JBI data extraction checklist through Microsoft Excel, and then exported to STATA 17 for further analysis. DerSimonian and Laird's estimator was used to calculate the pooled effect size in the random-effects model. Statistics such as the Cochran Q test and I2 test were employed to measure heterogeneity. Egger's test and the funnel plot were used to look for publication bias. This systematic review and meta-analysis used 16 studies from Sub-Saharan Africa to estimate the proportion of malnutrition among 2,120 children with cerebral palsy. The pooled proportion of malnutrition among children with cerebral palsy in Sub-Saharan Africa by using random-effects model analysis was found to be 59.7% (95% CI; 49.8-69.6). The proportion of malnutrition was also estimated by sample sizes categorized as ≤ 120 and > 120, and the proportion of malnutrition was found to be 54.0 (95% CI: 44.7-63.3) and 64.5 (95% CI: 50.5-78.5). Moreover, the proportion of malnutrition was estimated by accounting for the difference in the year of publication. In this regard, the study classified before ≤ 2017 and > 2017, and the proportion of malnutrition was found to be 53.7 (95% CI: 38.0-69.3) and 62.5 (95% CI: 49.7-75.3) in Sub-Saharan Africa respectively. Malnutrition among children with cerebral in Sub-Saharan Africa was found to be very high. Hence, enhancing and developing strategic guidelines for malnutrition screening, prevention, and nutritional support are crucial among children with cerebral palsy. Furthermore, systematic review, randomized control trials, and qualitative studies are recommended to understand the burden more among children with cerebral palsy in the continent.

Prevalence and patterns of cerebral venous sinus thrombosis following vestibular schwannoma surgery: a systematic review and meta-analysis.

Cerebral venous sinus thrombosis (CVST) is a potentially serious complication following surgical treatment of vestibular schwannoma, a benign tumor originating from Schwann cells of the vestibulocochlear nerve. This study aimed to determine the prevalence of CVST following surgical treatment of vestibular schwannoma and the factors contributing to its occurrence. Two independent researchers searched the global databases of PubMed, Web of Science, Scopus, and the Cochrane Library up to September 01, 2023. We employed a random-effects model for data analysis. Heterogeneity was evaluated using the I2 test. To assess the quality of the studies meeting our inclusion criteria, we employed the Joanna Briggs Institute Critical Appraisal Checklist. We included 23 articles in this meta-analysis. The pooled prevalence of CVST after vestibular schwannoma surgery was 6.4% (95%CI 3.4-11.5%). The pooled prevalence of CVST following the retrosigmoid (RS), translabyrinthine (TL), and middle cranial fossa (MCF) approaches was 4.8% (95%CI 2.0-11.0%), 9.6% (95%CI 4.3-20.3%) and 9.9% (95%CI 1.6-42.2%), respectively, revealing a significant difference between the TL and the RS approaches (Odds ratio=2.10, 95%CI 1.45-3.04, P< 0.001).The sigmoid sinus exhibited the highest post-operative thrombosis rate (7.9%), surpassing the transverse sinus (3.7%) and involvement of both sigmoid and transverse sinuses (1.6%), respectively. No significant associations were found with demographic or surgical factors. In the current meta-analysis, we identified a 6.4% CVST prevalence following vestibular schwannoma surgery, with varying rates depending on the surgical approach. No significant associations with patient or surgical factors were found, emphasizing the need for heightened clinical vigilance and further research in this context. PROSPERO ID: CRD42023453513.

Evaluation of vaccine effectiveness of mRNA COVID-19 vaccines in children: a systematic review and meta-analysis.

To evaluate the vaccine effectiveness (VE) of mRNA COVID-19 vaccines in children using a meta-analysis approach. Relevant studies on the use of mRNA COVID-19 vaccines in children were identified through computerized searches. VE-related indicators were extracted, and data analysis was performed using the R software with the meta-package. This study included a total of 12 relevant articles involving 9,963,732 participants from multiple centers in different countries, including the United States, Canada, Singapore, Israel, South Korea, and Qatar. The administered vaccine types included BNT162b2 and mRNA-1273. Participants were categorized into partially immunized (one dose of vaccine) and fully immunized (two doses of vaccine). Four articles reported VE after one dose of vaccine, while 12 reported VE after two doses. Heterogeneity analysis indicated significant heterogeneity among the studies, warranting the use of a random-effects model for analysis. Meta-analysis results revealed that the VE of partial immunization ranged from 16.61 (95% CI: 6.32-25.77) to 34.30 (95% CI: 24.21-43.04), with a pooled VE of 22.80 (95% CI: 15.68-29.32). The VE after full immunization ranged from 16.14 (95% CI: 14.42-17.83) to 90.47 (95% CI: 67.42-97.21), with a pooled VE of 56.17 (95% CI: 41.12-67.37). Meta-regression analysis showed no statistically significant correlation between VE and time (p>0.05). Both partial and full immunization of the BNT162b2 mRNA vaccine provide benefits in reducing infection rates. VE varies over time and is closely associated with viral mutations and waning immunity. The specific mechanisms require further investigation.

Early Versus Late Drainage Removal in Patients Who Underwent Pancreaticoduodenectomy: A Comprehensive Systematic Review and Meta-analysis of Randomized Controlled Trials Using Trial Sequential Analysis

BackgroundThe superiority of early drain removal (EDR) versus late (LDR) after pancreaticoduodenectomy (PD) has been demonstrated only in RCTs.MethodsA meta-analysis was conducted using a random-effects model and trial sequential analysis. The critical endpoints were morbidity, redrainage, relaparotomy, and postoperative pancreatic fistula (CR-POPF). Hemorrhage (PPH), delayed gastric emptying (DGE), length of stay (LOS), and readmission rates were also evaluated. Risk ratios (RRs) and mean differences (MDs) with a 95% confidence interval (CI) were calculated. Type I and type II errors were excluded, comparing the accrued sample size (ASS) with the required sample size (RIS). When RIS is superior to ASS, type I or II errors can be hypothesized.ResultsASS was 632 for all endpoints except DGE and PPH (557 patients). The major morbidity (RR 0.55; 95% CI 0.32–0.97) was lower in the EDR group. The CR-POPF rate was lower in the EDR than in the LDR group (RR 0.50), but this difference is not statistically significant (95% CI 0.24–1.03). The RIS to confirm or exclude these results can be reached by randomizing 5959 patients. The need for percutaneous drainage, relaparotomy, PPH, DGE, and readmission rates was similar. The related RISs were higher than ASS, and type II errors cannot be excluded. LOS was shorter in the EDR than the LDR group (MD − 2.25; 95% CI − 3.23 to − 1.28). The RIS was 567, and type I errors can be excluded.ConclusionsEDR, compared with LDR, is associated with lower major morbidity and shorter LOS.

Knowledge, attitude and practice of home management of diarrhea among under-five children in East Africa: A systematic review and meta-analysis.

Diarrhea is particularly prevalent in low-income or marginalized populations because these groups have less access to clean water sources, hygienic conditions, and healthcare. Dehydration due to electrolyte and fluid loss is the main cause of deaths associated with diarrhea. An especially important factor in this death from dehydration is the caregivers' knowledge, attitude, and diarrhea management techniques. While a number of research have been done on managing diarrhea at home, the results tend not to be consistent. This systematic review and meta-analysis aimed to assess the pooled estimate of knowledge, attitude and practice of home-based management of diarrhea in East Africa. Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines was used to search articles from electronic databases (Cochrane library, Ovid platform (Medline, Embase, and Emcare), Google Scholar, CINAHL, PubMed, and institutional repositories in East Africa countries. The last search date was on 01/06/ 2023 Gregorian Calendar. The authors extracted year of publication, country, study design, knowledge level, attitude level and practice level of home-based management of diarrhea. A weighted inverse variance random-effects model was used to estimate the pooled prevalence of knowledge, attitude and practice of home-based management of diarrhea. Subgroup analysis was done by country, and sample size. Publication bias and sensitivity analysis were also done. A total of 19 articles with (n = 7470 participants) were included for the final analysis. From the random-effects model analysis, the pooled prevalence of good practice, good knowledge and favorable attitude towards home based management of diarrhea in East Africa was found to be 52.62% (95% CI: 45.32%, 59.92%) (95% CI: I2 = 78.3%; p < 0.001), 37.44% (95% CI: 26.99%, 47.89%) (95% CI: I2 = 89.2%; p < 0.001) and 63.05% (95% CI: 35.7%, 90.41%) (95% CI: I2 = 97.8%; p < 0.001) respectively. The level of good knowledge, attitude and practice of home based management of diarrhea in East Africa is found to be low. A collaborative effort from different stakeholders to enhance the knowledge, attitude and practice is needed to tackle the burden of diarrhea and its consequences.

Dental caries and mean values of DMFT among children with cerebral palsy: a systematic review and meta-analysis

IntroductionOne of the most prevalent causes of physical disability in children is cerebral palsy (CP), which is a series of complicated neurological disorders. Children with cerebral palsy suffer from multiple problems and potential disabilities, including dental caries. Hence, this study aimed to determine the pooled prevalence of dental caries and mean DMFT (Decayed, Missed, and Filled Permanent Teeth) among children with cerebral palsy in Africa and Asia.MethodsA comprehensive search of the literature was made to locate relevant studies in PubMed/Medline, HINARI, Web of Science, Science Direct, the Cochrane Library, the Worldwide Science Database, and Google Scholar. The data were extracted in Microsoft Excel and transferred to Stata version 17 software for further analysis. A random-effect model was employed to estimate the pooled prevalence of dental caries and the pooled mean value of DMFT among children with cerebral palsy in Africa and Asia. Heterogeneity between studies was checked using the Cochrane Q test and I2 test statistics. Sub-group analysis by continent was done, and sensitivity analysis was checked. A small study effect was checked using Egger’s statistical test at the 5% level of significance.ResultsIn this study, 25 original studies conducted in 17 countries in Africa and Asia that fulfilled the eligibility criteria were included in the review. The overall pooled prevalence of dental caries in Africa and Asia among children with cerebral palsy was 55.6% (95% CI: 42.4, 68.8). The pooled prevalence of dental caries among children with cerebral palsy in Africa was 42.43% (95% CI: 30.39, 54.58), and it was slightly higher in Asia with 64% (95% CI: 48.32, 79.72). In the random effect model analysis, the pooled mean DMFT of dental caries in children with cerebral palsy was 2.25 (95% CI: 1.86, 2.64). The pooled mean DMFT in Africa was 1.47 (95% CI: 0.86, 2.09), and in Asia it was 3.01 (95% CI: 2.43, 3.60).ConclusionIn this study, we found that children with cerebral palsy experienced an alarming rate of dental caries. In these settings, dental caries affected roughly more than half of the children with cerebral palsy.

The utility of coping through emotional approach: A meta-analysis.

A systematic review and meta-analysis was conducted to examine associations between attempts to cope with stressors through the two facets of emotional approach coping (EAC; i.e., processing and expressing stressor-related emotions) and indicators of physical and mental health. EBSCO databases including MEDLINE, PsycINFO, and Cochrane Collections were searched from inception to November 2022. In all, 86 studies were included in a meta-analytic evaluation using a random-effects model and meta-regression analysis. EAC was associated with better overall health (r = .05; p = .04; 95% confidence interval = [.003, .10]). Emotional expression (EE) and emotional processing (EP) also were positively associated with better overall health, although these relationships were not statistically significant. In meta-regressions examining specific health domains, EAC was linked to better health in biological/physiological, physical, and resilience-related psychological adjustment domains, as well as to worse outcomes in the risk-related psychological adjustment and mental/emotional distress domains. Results for EE and EP mirrored this pattern; however, only EP was associated with more engagement in health-promoting behaviors. Coping with stressors through emotional approach appears to be associated with better mental and physical health, with some observed differences for EE and EP. The literature on EAC and health is marked by heterogeneity across study methodologies and measures. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The effect of a ketogenic diet on inflammation-related markers: a systematic review and meta-analysis of randomized controlled trials.

Despite the important role of inflammation-related factors on the occurrence of chronic diseases, there is still conflicting evidence about the effects of the ketogenic diet (KD) on these factors. In order to obtain a better viewpoint, this study aimed to comprehensively investigate the effects of a KD on inflammation-related markers. To find pertinent randomized controlled trials up to August 2023, databases including PubMed/Medline, Web of Science, Scopus, Cochrane Library, and Embase were searched. This study included all randomized controlled trials investigating the effects of a KD on C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-8, and IL-10 levels. Pooled weighted mean difference (WMD) and 95% confidence intervals (CIs) were achieved by random-effects model analysis for the best estimation of outcomes. Forty-four studies were included in this article. The pooled findings showed that a KD has an effect on lowering TNF-α (WMD: -0.32 pg/mL; 95% CI: -0.55, -0.09; P = 0.007) and IL-6 (WMD: -0.27 pg/mL; 95% CI: -0.52, -0.02; P = 0.036) compared with control groups. However, no significant effect was reported for others inflammation marker-related levels. The results of the subgroup analysis showed that, in trials following the KD for ≤8 weeks and in people aged ≤50 years, the reduction in TNF-α levels was significantly higher than in other groups. In addition, in people with a body mass index greater than 30 kg/m2 compared to a body mass index ≤30 kg/m2, IL-6 levels decreased to a greater extent after receiving the KD. Consequently, adherence to a KD appears to improve some markers associated with inflammation, including TNF-α and IL-6.

Effects of Physical Exercise on Telomere Length in Healthy Adults: Systematic Review, Meta-Analysis, and Meta-Regression.

Physical exercise is one of the main nonpharmacological treatments for most pathologies. In addition, physical exercise is beneficial in the prevention of various diseases. The impact of physical exercise has been widely studied; however, existing meta-analyses have included diverse and heterogeneous samples. Therefore, to our knowledge, this is the first meta-analysis to evaluate the impact of different physical exercise modalities on telomere length in healthy populations. In this review, we aimed to determine the effect of physical exercise on telomere length in a healthy population through a meta-analysis of randomized controlled trials. A systematic review with meta-analysis and meta-regression of the published literature on the impact of physical exercise on telomere length in a healthy population was performed. PubMed, Cochrane Library, SCOPUS, Web of Science, and Embase databases were searched for eligible studies. Methodological quality was evaluated using the Risk Of Bias In Nonrandomized Studies of Interventions and the risk-of-bias tool for randomized trials. Finally, the certainty of our findings (closeness of the estimated effect to the true effect) was evaluated using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). We included 9 trials that met the inclusion criteria with fair methodological quality. Random-effects model analysis was used to quantify the difference in telomere length between the exercise and sham groups. Meta-analysis showed that exercise did not significantly increase telomere length compared with the control intervention (mean difference=0.0058, 95% CI -0.05 to 0.06; P=.83). Subgroup analysis suggested that high-intensity interventional exercise significantly increased telomere length compared with the control intervention in healthy individuals (mean difference=0.15, 95% CI 0.03-0.26; P=.01). Furthermore, 56% of the studies had a high risk of bias. Certainty was graded from low to very low for most of the outcomes. The findings of this systematic review and meta-analysis suggest that high-intensity interval training seems to have a positive effect on telomere length compared with other types of exercise such as resistance training or aerobic exercise in a healthy population.
