Estimating Heterogeneity and Pooled Prevalence of Classical Swine Fever in Pigs in India: A Meta-analysis

Background: Classical swine fever (CSF) is caused by small enveloped RNA virus that belongs to the Flaviviridae family and causes high morbidity and mortality events for pig farming. In India, it is highly prevalent but with varied distribution in various geographical areas resulting in substantial economic losses to farmers. The discrepancy in prevalence estimates across studies needs to be evaluated in order to strengthen the prevention and control strategies of CSF in pigs. The aim of the present study was to provide the pooled estimate of the prevalence of classical swine fever (CSF) in India and to examine the consistency of those estimates between published studies.Methods: The data regarding prevalence of CSF in 7045 pigs were compiled from 22 published studies using comprehensive literature search for period from 1998 to 2018. The pooled prevalence of CSF was obtained under random effects model and heterogeneity between studies was determined using I² Index. Representation of meta-analysis was done using forest plot and followed by funnel plot, Baujat plot and radial plot.Result: The result of Meta-analysis revealed that pooled estimate of prevalence of CSF under random effects model was 45% (95% confidence interval: 35, 55%) in India. The heterogeneity statistic (Q) was found to be significant (p less than 0.001) with I² = 98% which indicated that prevalence of CSF was inconsistent between the studies. Likewise, results of funnel plot and Radial plot indicated heterogeneity between studies. Most influential studies for overall heterogeneity were identified using Baujat and radical plots.

Abstract Backgrouand Because of the end of permanent teeth eruption duration, 12 years old age has encountered with a great importance. The aim of this study is to determine DMFT status of this age group using systematic review and meta-analysis method. Methods Internal and external databases on the basis of inclusion and exclusion criteria were searched using the considered keywords. Heterogeneity and the quality of studies were assessed using I2 index and STROBE checklist. Forest plot was plotted using Random Effects Model. Funnel plot and Eggers’ test used to indicate publication bias. Results 95 studies with 12145 total persons and 393 mean person in each study were entered to the final step of meta-analysis. Using Random Effects model, total mean DMFT of 12 years olds was estimated 2.01 (1.83-2.19) and separately for girls and boys was estimated 2.10 (1.95-2.26) and 2.16 (1.94-2.38), respectively. Funnel plot and Eggers’ test were insignificant which indicate reliability of the study results and low publication bias. Conclusion The results indicated that mean DMFT of 12 years old population is 2.01 which this mean in boys is higher than girls ones. These permanent teethes need to be in the mouth lifetime, but have encountered with problems in the age of eruption. Review and reforms in dental health system seem necessary.

Prevalence Of Depression

Introduction COVID-19 pandemic is having a devastating effect on the mental health and wellbeing of healthcare providers (HCPs) globally. This review is aimed at determining the prevalence of depression, anxiety, stress, fear, burnout and resilience and its associated factors among HCPs in Asia during the COVID-19 pandemic. Material and methods We performed literature search using 4 databases from Medline, Cinahl, PubMed and Scopus from inception up to March 15, 2021 and selected relevant cross-sectional studies. Publication bias was assessed using funnel plot. Random effects model was used to estimate the pooled prevalence while risk factors were reported in odds ratio (OR) with 95% CI. Results We included 148 studies with 159,194 HCPs and the pooled prevalence for depression was 37.5% (95%CI: 33.8–41.3), anxiety 39.7(95%CI: 34.3–45.1), stress 36.4% (95%CI: 23.2–49.7), fear 71.3% (95%CI: 54.6–88.0), burnout 68.3% (95%CI: 54.0–82.5), and low resilience was 16.1% (95%CI: 12.8–19.4), respectively. The heterogeneity was high (I2>99.4%). Meta-analysis reported that both females (OR = 1.48; 95% CI = 1.30–1.68) and nurses (OR = 1.21; 95%CI = 1.02–1.45) were at increased risk of having depression and anxiety [(Female: OR = 1.66; 95% CI = 1.49–1.85), (Nurse: OR = 1.36; 95%CI = 1.16–1.58)]. Females were at increased risk of getting stress (OR = 1.59; 95%CI = 1.28–1.97). Conclusion In conclusion, one third of HCPs suffered from depression, anxiety and stress and more than two third of HCPs suffered from fear and burnout during the COVID-19 pandemic in Asia.

Undiagnosed Diabetes Mellitus

Abstract Background Despite the high prevalence of diabetes in Africa, the extent of undiagnosed diabetes in the region is still poorly understood. This systematic review and meta-analysis was designed to determine the pooled prevalence of undiagnosed diabetes mellitus among adults in Africa. Methods We conducted a systematic desk review and electronic web-based search of PubMed, Google Scholar, EMBASE, and the World Health Organization’s Hinari portal (which includes the SCOPUS, African Index Medicus, and African Journals Online databases), identifying peer-reviewed research studies on the prevalence of undiagnosed diabetes among adult individuals using pre-defined quality and inclusion criteria. We ran our search from June 1, 2018 to Jun 14, 2020. We extracted relevant data and presented descriptive summaries of the studies in tabular form. The I2 test was used to assess heterogeneity across studies. A random effects model was used to estimate the pooled prevalence of undiagnosed diabetes mellitus at a 95% confidence interval (CI). Funnel plot asymmetry and Egger’s tests were used to check for publication bias. The final effect size was determined by applying a trim and fill analysis in a random-effects model. Results Our search identified 1442 studies amongst which 23 articles were eligible for inclusion in the final meta-analysis. The average pooled prevalence of undiagnosed diabetes mellitus among adults was 3.85 (95% CI: 3.10–4.60). The pooled prevalence of undiagnosed diabetes mellitus based on geographic location was 4.43 (95% CI: 3.12–5.74) in Eastern Africa; 4.72 (95% CI: 2.64–6.80) in Western Africa; 4.27 (95% CI: 1.77–6.76) in Northern Africa and 1.46 (95%CI: 0.57–2.34) in southern Africa respectively. Conclusion Our findings indicate a high prevalence of undiagnosed diabetes in Africa and suggest that it may be more prevalent in Western Africa than the rest of the regions. Given the high levels of undiagnosed diabetes in the Africa region, more attention should be paid to incorporating diabetes screening and treatment services into existing diabetes related programs to reduce the prevalence of undiagnosed cases.

Objective To systematically review the literature to determine the prevalence and clinical outcomes of second primary oropharyngeal squamous cell carcinoma (OPSCC). Data Sources Search strategies created with a medical librarian were implemented using multiple databases in October 2019. Review Methods The population of interest included adults age >18 years with a p16+ or human papillomavirus-positive OPSCC. The outcome was a synchronous or metachronous second primary OPSCC. Inclusion and exclusion criteria were designed to capture all study designs. In total, 685 records were identified by the search strategy. Two reviewers independently performed the review, extracted data, and performed a quality assessment. Primary Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A random-effects model was used for the meta-analysis. Results A total of 2470 patients with 35 second primary OPSCCs from 15 studies were identified. The pooled prevalence of second primary OPSCC was 1.4% (range, 0%-14.3%). In the random-effects model, the prevalence was estimated at 1.3% (95% CI, 0.7%-2.3%; P = .51, I2 = 52%). Of the 30 patients with treatment information, 26 (86.7%) received surgical treatment, while 4 (13.3%) underwent nonsurgical therapy. Of the 29 patients with available survival information, 22 (75.9%) had no evidence of disease at last follow-up, 5 (17.2%) ultimately died of disease, and 2 (6.9%) were alive with disease. Conclusion Overall, the rate of second primary OPSCC in patients with an index p16+ OPSCC is low, and most patients are successfully treated. Insufficient evidence currently exists to recommend routine elective tonsillectomy during surgical treatment of p16+ OPSCC.

New Mutations

Since its first detection in December 2019, more than 232 million cases of COVID-19, including 4.7 million deaths, have been reported by the WHO. The SARS-CoV-2 viral genomes have evolved rapidly worldwide, causing the emergence of new variants. This systematic review and meta-analysis was conducted to provide a global mutational profile of SARS-CoV-2 from December 2019 to October 2020. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA), and a study protocol was lodged with PROSPERO. Data from 62 eligible studies involving 368,316 SARS-CoV-2 genomes were analyzed. The mutational data analyzed showed most studies detected mutations in the Spike protein (n = 50), Nucleocapsid phosphoprotein (n = 34), ORF1ab gene (n = 29), 5′-UTR (n = 28) and ORF3a (n = 25). Under the random-effects model, pooled prevalence of SARS-CoV-2 variants was estimated at 95.1% (95% CI; 93.3–96.4%; I2 = 98.952%; p = 0.000) while subgroup meta-analysis by country showed majority of the studies were conducted ‘Worldwide’ (n = 10), followed by ‘Multiple countries’ (n = 6) and the USA (n = 5). The estimated prevalence indicated a need to continuously monitor the prevalence of new mutations due to their potential influence on disease severity, transmissibility and vaccine effectiveness.

Vancomycin-Resistant Enterococci (VRE) are on the rise worldwide. Here, we report the first prevalence of VRE in Nigeria using systematic review and meta-analysis. International databases MedLib, PubMed, International Scientific Indexing (ISI), Web of Science, Scopus, Google Scholar, and African journals online (AJOL) were searched. Information was extracted by two independent reviewers, and results were reviewed by the third. Two reviewers independently assessed the study quality using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist. OpenMeta analyst was used. The random effect was used, and publication bias was assessed using a funnel plot. Between-study heterogeneity was assessed, and the sources were analysed using the leave-one-out meta-analysis, subgroup analysis, and meta-regression. Nineteen studies met the eligibility criteria and were added to the final meta-analysis, and the study period was from 2009–2018. Of the 2552 isolates tested, 349 were VRE, and E. faecalis was reported the most. The pooled prevalence of VRE in Nigeria was estimated at 25.3% (95% CI; 19.8–30.8%; I2 = 96.26%; p < 0.001). Between-study variability was high (t2 = 0.011; heterogeneity I2 = 96.26% with heterogeneity chi-square (Q) = 480.667, degrees of freedom (df) = 18, and p = 0.001). The funnel plot showed no publication bias, and the leave-one-out forest plot did not affect the pooled prevalence. The South-East region had a moderate heterogeneity though not significant (I2 = 51.15%, p = 0.129). Meta-regression showed that all the variables listed contributed to the heterogeneity except for the animal isolate source (p = 0.188) and studies that were done in 2013 (p = 0.219). Adherence to proper and accurate antimicrobial usage, comprehensive testing, and continuous surveillance of VRE are required.

Background: Coronavirus disease 2019 (COVID-19) started to spread globally since December 2019 from Wuhan, China. Headache has been observed as one of the clinical manifestations in COVID-19 patients. We aimed to conduct a comprehensive systematic review and meta-analysis to estimate the overall pooled prevalence of headache in COVID-19 patients.Methods: PubMed, Scopus, ScienceDirect, and Google Scholar databases were searched to identify studies published between December 2019 and March 2020. Adult (≥18 years) COVID-19 patients were considered eligible. We used random-effects model to estimate the pooled prevalence with 95% confidence intervals (CIs). Quality assessment was done using the Joanna Briggs Institute critical appraisal tools. This study is registered with PROSPERO (CRD42020182529).Results: We identified 2,055 studies, of which 86 studies (n = 14,275, 49.4% female) were included in the meta-analysis. Overall, the pooled prevalence of headache in COVID-19 patients was 10.1% [95% CI: 8.76–11.49]. There was no significant difference of headache prevalence in severe or critical vs. non-severe (RR: 1.05, p = 0.78), survived (recovered or discharged) vs. non-survived (RR: 1.36, p = 0.23), and ICU vs. non-ICU (RR: 1.06, p = 0.87) COVID-19 patients. We detected 64.0, 34.9, and 1.1% of the included studies as high, moderate, and low quality, respectively.Conclusions: From the first 4-month data of the outbreak, headache was detected in 10.1% of the adult COVID-19 patients.

Purpose: Vesicoureteral reflux (VUR) is a risk factor for various renal problems like recurrent urinary tract infections (UTIs), pyelonephritis, renal scarring, hypertension, and other renal parenchymal defects. The interventions followed by pediatricians include low-dose antibiotic treatment, surgical correction, and endoscopy. This meta-analysis aimed to assess the advantages and drawbacks of various primary VUR treatment options. Search Strategy: The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, reference lists of journals, and abstracts from conference proceedings were all used to find randomized controlled trials. The articles were retrieved from 1985 till 2020. Twenty articles were used for the data analysis. Criteria for Selection: Surgery, long-term antibiotic prophylaxis, noninvasive techniques, and any mix of therapies are also options for treating VUR. Collection and Interpretation of Data: Two authors searched the literature separately, determining research qualifications, assessing accuracy, and extracting and entering results. The odds ratio (OR) of these studies was used to construct the forest plot. The random-effects model was used to pool the data. Also, the random-effects model was used with statistical significance at a p value < 0.05 to assess the difference in side effects after treatment of VUR using different modalities. Results: We found no statistically significant differences between surgery plus antibiotics and antibiotic alone-treated patients in terms of recurrent UTIs (OR = 0.581; 95% confidence interval [CI] 0.259–1.30), renal parenchymal defects (OR = 1.149; 95% CI 0.75–1.754), and renal scarring (OR = 1.042; 95% CI 0.72–1.50). However, the risk of developing pyelonephritis after surgical treatment of VUR was lesser than that in the conservative approach, that is, antibiotics (OR = 0.345; 95% CI 0.126–0.946.), positive urine culture (OR = 0.617; 95% CI 0.428–0.890), and recurrent UTIs were more common in the placebo group than in the antibiotic group (p < 0.05; OR = 0.639; 95% CI 0.436–0.936) which is statistically significant. Conclusion: Based on current research, we recommend that a child with a UTI and significant VUR be treated conservatively at first, with surgical care reserved for children who have issues with antimicrobials or have clinically significant VUR that persists after several years of follow-up.

Abstract Background Though cervical cancer is largely preventable, it is still the second most common female cancer globally and the leading cause of cancer deaths among females in African. Though many efforts have been done to study the burden of the disease in Ethiopia, primary studies examining the prevalence of precancerous cervical lesions are fragmented. Hence, this systematic review and meta-analysis is aimed at estimating the pooled prevalence of precancerous cervical lesion and its trends in Ethiopia. Methods This systematic review and meta-analysis was conducted using the following electronic databases. PubMed, Web of Science, SCOPUS, Science Direct, Google Scholar, African Index Medicus (AIM), African Journals Online databases, and Addis Ababa and Bahir Dar Universities research repositories were searched following the Preferred Items for Systematic Review and Meta-analysis (PRISMA) Guideline. STATA 15 statistical software was used to analyze the data. The quality of the included studies was assessed using the Joanna Briggs Institute (JBI) quality appraisal tool for meta-analysis. Heterogeneity between studies was assessed using the Cochrane Q test and I2 test statistics based on the random effects model. A random effects model was computed to estimate the pooled prevalence of precancerous cervical lesion in Ethiopia. Finally, the trend of precancerous cervical lesion in the country was presented. Result Seventeen studies with a total of 26,112 participants were included in the analysis. The pooled prevalence of precancerous cervical lesion was 15.16 (95% CI 10.16–19.70). The subgroup analysis by region showed the highest prevalence of precancerous cervical lesion at the Southern Nations and Nationalities Peoples Region (19.65%; 95% CI 15.51–23.80). The trend of precancerous cervical lesion prevalence showed an increased pattern over time. Conclusion Approximately one among six of the study participants had precancerous cervical lesion. The trend also showed that there is still an increasing precancerous cervical lesion in Ethiopia. Best practices in achieving high vaccination coverage shall be informed by practices in other successful countries.
