Polio Eradication in Nigeria and India: A Systematic Review of Challenges and Successes

Background: The global eradication of polio is considered an emergency and an unaccomplished task until completely eliminated. Vaccinating children against the polio virus confers immunity on them and breaks the transmission of the polio virus. Afghanistan, Nigeria and Pakistan remain the only three countries in the world that have not eliminated polio. The aims of this paper were to: (1) to identify the factors that impact the failure to eliminate polio from Nigeria and (2) determine the factors that led to the successful elimination of polio from India. Methodology: A systematic literature review was carried out to meet the above research objectives. Methods: Four electronic databases were searched (Cochrane Library, Medline, PubMed and Google Scholar) and articles that fulfilled the inclusion and exclusion criteria were selected and critically appraised. Results: In all, 98 articles were retrieved. After selection based on our selection criteria, fourteen studies were identified and included in the study. These were 5 systematic reviews: 3 cross-sectional studies, 3 mixed methods studies, 2 case-control studies and one quantitative (survey) study. In all, seven themes were identified from the review of the articles. Four themes were identified from the factors associated with the failure to eliminate polio from Nigeria: (1) Failure of the oral polio vaccine (OPV); (2) Institutional and geographical failures in vaccine programs; (3) Program and campaign management limitations; and (4) Vaccine refusal. Similarly, three themes were identified from the factors that contributed to the elimination of polio from India: (1) Replacement of the trivalent OPV with the monovalent and bivalent OPVs; (2) Implementation of intensive social mobilization strategies; and (3) Effective program micro planning and campaign management. Conclusion: Based on the findings from the literature review, we highlight areas where Nigeria can learn from India in its quest to eliminate polio. These factors can form the basis for future theoretical and policy reforms in the fight against polio not only in Nigeria but in countries where it remains endemic. Further research should compare the success of polio eradication in other countries.

Vitamin D Levels

Abstract Background: Current studies suggest that vitamin D deficiency during pregnancy can produce a certain effect for preterm birth, but there is no research showing whether vitamin D deficiency has a consistent effect in different pregnancies; thus, we conducted a systematic review and meta-analysis of 24 observational studies, grouping them according to the gestational age at the time of serum sampling, to investigate whether vitamin D deficiency in different periods of gestation has different effects on preterm birth and to provide an evidence-based basis for pregnant women to measure and supplement vitamin D. Methods: The databases PubMed-Medline, EMBASE, the Cochrane Library, Web of Science, EBSCO, CBM, and CNKI were searched until July 2019. Two researchers independently assessed the eligibility and quality of studies, and STATA 12.0 software was used for meta-analysis. Result: Seven cohort studies, 13 case-control studies, and four cross-sectional studies were included from 2500 articles by inclusion and exclusion criteria. After adjusting for age, race, and other confounding factors, meta-analysis results showed that vitamin D deficiency in the first trimester, the second trimester and the third trimester did not increase the risk of preterm birth (odds ratio (OR) = 1.01, 95% confidence interval (CI) (0.88, 1.16), P = 0.867; OR = 1.12, 95%CI (0.92, 1.37), P = 0.249; OR = 1.05, 95%CI (0.87, 1.27), P = 0.602). However, there was moderate heterogeneity in the study of vitamin D deficiency in the second trimester, and subgroup analysis suggested that vitamin D deficiency in the second trimester may increase the risk of preterm birth (OR = 1.33, 95%CI (1.15, 1.54), P = 0.000). A sensitivity analysis of the second trimester showed that excluding any one study did not significantly change the results. Conclusions: Vitamin D deficiency in early and late pregnancy may not be associated with preterm birth, while vitamin D deficiency in middle pregnancy is likely to have an important effect on preterm birth. Vitamin D levels should be measured in the second trimester of pregnancy, and vitamin D supplements should be provided if necessary.

Abstract introduction: HIV and HCV is a health concern in the word. Therefore, this systematic review and meta-analysis protocol study is aimed to estimate the incidence of HIV and HCV among People who inject drugs (PWID) by applying mathematical modeling. The primary purpose of this systematic review is to identify and review existing studies of HIV and HCV incidence in people who inject drugs, that use mathematical modeling. Methods and analysis: Studies including cohort, cross-sectional, case–control studies which were conducted to estimate incidence of HIV and HCV based on mathematical or evaluated effectiveness of mathematical models will be considered to enroll the review; a comprehensive search with Cochrane approach would be applied to identify relevant studies in electronic databases in the period of 2000 to 2019. This protocol was prepared according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) and we will search PubMed, EMBASE, Opengrey, WOS, SCOPUS, and Cochrane Library with no restriction of language. Study selection and data extraction will be performed by two independent reviewers. Assessment of risk of bias will be implemented using three quality test tools including Newcastle Ottawa Scale and ROBIS scale for cross-sectional studies and quantitative studies quality test tool for observational and interventional studies for other study Publication bias will be assessed by funnel plots, Begg’s and Egger’s tests. Heterogeneity will be evaluated using the I2 statistic and the χ2 test. In addition, subgroup analyses will be conducted for population and the secondary outcomes.

ObjectiveWe performed a systematic review and a meta-analysis to estimate the prevalence of human papillomavirus (HPV) in ovarian cancer.MethodsA comprehensive search of the Cochrane Library, MEDLINE, CANCERLIT, LILACS, Grey literature and EMBASE was performed for articles published from January 1990 to March 2012. The following MeSH (Medical Subject Headings) terms were searched: “ovarian tumor” or “ovarian cancers” and “HPV” or “human papillomavirus.” Included were case-control and cross-sectional studies, prospective or retrospective, that evaluated clinical ovarian cancer and provided a clear description of the use of in situ hybridization, Southern blot hybridization, and polymerase chain reaction. The statistical analysis was performed using REVMAN 5.0.ResultsIn total, 24 primary studies were included in this meta-analysis. Studies from 11 countries on 3 continents contained data on HPV and ovarian cancer, including 889 subjects. Overall, the HPV prevalence in patients with ovarian cancer was 17.5 (95% confidence interval [CI], 15.0%–20.0%). Human papillomavirus prevalence ranged from 4.0% (95% CI, 1.7%–6.3%) in Europe to 31.4% (95% CI, 26.9%–35.9%) in Asia. An aggregate of 4 case-control studies from Asia showed an odds ratio of 2.48 (95% CI, 0.64–9.57).ConclusionsWe found a high prevalence of HPV-positive DNA in ovarian cancer cases, but the role of HPV in ovarian cancer remains inconclusive. Further studies are needed to control case to answer this question.

Vitamin C is important in preventing and slowing the progression of many diseases. There is significant evidence linking periodontal disease and vitamin C. We aimed to systematically review studies addressing the relationship between vitamin C and periodontal disease and the preventive ability of vitamin C against periodontal disease. Electric searches were performed using PubMed, EMBASE, Cochrane Library, and Web of Science. Studies addressing the relationships between periodontal disease and vitamin C in adults aged over 18 years were included. Quality assessment was done using Critical Appraisal Skills Program guideline and GRADE-CERQual. Seventy hundred and sixteen articles were retrieved and fifteen articles (7 cross-sectional studies, 2 case-control studies, 2 cohort studies, and 4 randomized controlled trial [RCT]) were selected by reviewing all articles. Vitamin C intake and blood level were negatively related to periodontal disease in all 7 cross-sectional studies. Subjects who suffer from periodontitis presented lower vitamin C intake and lower blood vitamin C level than subjects without periodontal disease in the two case-control studies. Patients with lower dietary intake or lower blood level of vitamin C showed greater progression of periodontal disease than did the controls. Intervention using vitamin C administration improved gingival bleeding in gingivitis but not in periodontitis. Alveolar bone absorption was also not improved. The present systematic review suggested that vitamin C contributes to reduced risk of periodontal disease.

ObjectivesThere has been increasing epidemiological research examining the association between vision impairment (VI) and cognitive impairment and how poor vision may be a modifiable risk factor for cognitive decline. The objective of this systematic review is to synthesise the published literature on the association of VI with cognitive decline, cognitive impairment or dementia, to aid the development of interventions and guide public policies pertaining to the relationship between vision and cognition.MethodsA literature search was performed with Embase, Medline and Cochrane library databases from inception to March 2020, and included abstracts and articles published in peer-reviewed journals in English. Our inclusion criteria included publications that contained subjective/objective measures of vision and cognition, or a diagnosis of VI, cognitive impairment or dementia. Longitudinal or cross-sectional studies with ≥100 participants aged >50 years were included. The search identified 11 805 articles whose abstracts underwent screening by three teams of study authors. Data abstraction and quality assessment using the Effective Public Health Practice Project Quality Assessment Tool were performed by one author (NN). 10% of the articles underwent abstraction and appraisal by a second author (LA/VV), results were compared between both and were in agreement.Results110 full-text articles were selected for data extraction, of which 53 were cross-sectional, 43 longitudinal and 14 were case–control studies. The mean age of participants was 73.0 years (range 50–93.1). Ninety-one (83%) of these studies reported that VI was associated with cognitive impairment.ConclusionOur systematic review indicates that a majority of studies examining the vision–cognition relationship report that VI is associated with more cognitive decline, cognitive impairment or dementia among older adults. This synthesis supports the need for additional research to understand the mechanisms underlying the association between VI and cognitive impairment and to test interventions that mitigate the cognitive consequences of VI.

Objective.It has been reported that there is an association between rheumatoid arthritis (RA) and increased susceptibility to sexual dysfunction (SD). This systematic review and metaanalysis aimed to investigate whether RA was a risk factor for SD.Methods.MEDLINE (PubMed), EMBASE, and the Cochrane Library were systematically searched for all studies assessing sexual function in patients with RA. The association between RA and risk of SD was summarized using relative risk (RR) with 95% CI.Results.Overall, 44,745 participants (mean age 43.2 yrs) were included from 7 studies (4 cross-sectional and 3 case-control studies). Of these, 6642 were patients with RA, with the mean disease duration from 5.7 years to 12.17 years. The methodological qualities of the included studies were judged as moderate to high. Synthesis of results demonstrated that RA was significantly associated with an increased risk of SD in females (RR 1.73, 95% CI 1.36–2.22, p < 0.001; heterogeneity: I2 60.3%, p = 0.028) as well as in males (RR 1.99, 95% CI 1.64–2.43, p < 0.001). The outcomes related to the Grading of Recommendations Assessment, Development, and Evaluation approach showed that the absolute effect of RA on SD was 10 more per 1000 (6–15 more); the overall quality of evidence was rated as low.Conclusion.Evidence from included studies indicates that patients with RA have a significantly increased risk of SD, which suggests that both patients and clinicians should be aware of the potential role of RA in the development of SD.

Abstract Abstract 4629 Background: Seizures are frequently found in patients with autoimmune diseases such as lupus and APS. Recent publications concluded that APLAs are associated with seizures and their presence results in more poor control. Conversely, the presence of auto-antibodies directed against different targets, including APLA, voltage-gated potassium channels, c-aminobutyric acid B receptor, GAD, and others, have been identified in up to 20% of newly-diagnosed epilepsy patients and there is increasing evidence of their pathogenic role. Objective: We sought to evaluate the relationship between epilepsy and antiphospholipid antibodies (APLA) and/or antiphospholipid antibody syndrome (APS). This was done by means of a systematic review of the literature. We sought to answer four questions: 1) Are epilepsy and seizure disorders more prevalent among pts. with aPLAS/aPLAs?; 2) Is aPLAS more prevalent among patients with epilepsy or seizure disorders?; 3) In those with seizure disorders, is there a heightened prevalence of aPLAs?; 4) Does the presence and titre of aPLAs determine the severity and/or frequency of seizures, in these patients? Design/Methods: We conducted a systematic review to evaluate the relationship between APLA (including anticardiolipin Ab, anti beta-2-glycoprotein-1 Ab, and lupus anticoagulant) and epilepsy. We searched MEDLINE, EMBASE, Healthstar, the Cochrane library, LILACS, Scopus and grey literature. We included cohort, case-control, and cross-sectional studies studying the prevalence of epilepsy in patients with APS and/or +APLA, the prevalence of +APLA and/or APS in patients with epilepsy, and the severity of the seizures in patients with +APLA and/or APS. Results: The search retrieved 837 relevant references and 79 were retrieved for full review. We included in the final review 24 studies (19 case-control, 3 cohort and 2 cross-sectional). In 3 cohorts, including 1585 patients with APS, the frequency of epilepsy ranged between 3.4 and 8.5%. In 16 case-control studies, including 3893 patients, the OR for +APLA and/or APS in patients with epilepsy ranged from 0.60 to 13.3 in individual studies. In 2 case-control studies, including 804 patients, the OR for epilepsy in patients with +APLA and/or APS ranged from 0.83 to 2.82 in individual studies. An OR or RR could be calculated in only 17 studies, and within this group, twelve positive and five negative studies were identified. No meta-analysis was conducted due to the high heterogeneity of designs. In 4 studies, an association was found between +APLA and seizure frequency and severity. In positive studies there was no correlation between +APLA, epilepsy and cerebral ischemia. Conclusions: We conclude that +APLA/APS might be related with higher risk and severity of epilepsy, however further studies using accepted consensus definitions for APLA positivity, more stringent methodology and appropriate subgroup analysis are needed.

Background:: It is undeniable that diabetes may cause several health complications for the population. Many of these complications are associated with poor glycemic control. Due to this, strategies to handle this problem are of great clinical importance and may contribute to reducing the various complications from diabetes. Objective: : The aim of this study was to compare the effectiveness of the passion fruit peel flour versus turmeric flour on glycemic control. Methods: This is a systematic review and meta-analysis following the PRISMA protocol. The following inclusion criteria were applied: (1) Case-control studies, cohort studies, and clinical trials, due to the improved statistical analysis and, in restrict cases, cross-sectional studies; (2) Articles published in any language. The databases used for the search were PubMed, Scopus, Web of Science, Cochrane, and LILACS. A bias analysis and a meta-analyses were undertaken using R Studio (version 3.3.1) using effect- size models. Results: : A total of 565 studies were identified from which 11 met the inclusion and exclusion criteria. Through isolated analysis, the effectiveness of turmeric flour on glycemic control was in the order of 0.73 CI (Confidence Interval) (from 0.68 to 0.79) and the effectiveness of passion fruit peel flour was 0.32 CI (0.23 to 0.45). The joint analysis resulted in 0.59 CI (0.52 to 0.68). The assessment of blood glucose was by glycated hemoglobin levels. All values were significant at a p < 0.05 level. Conclusion: Both interventions showed significant effects on glycemic control.

Abstract Context: People with CHD are at increased risk for executive functioning deficits. Meta-analyses of these measures in CHD patients compared to healthy controls have not been reported. Objective: To examine differences in executive functions in individuals with CHD compared to healthy controls. Data sources: We performed a systematic review of publications from 1 January, 1986 to 15 June, 2020 indexed in PubMed, CINAHL, EMBASE, PsycInfo, Web of Science, and the Cochrane Library. Study selection: Inclusion criteria were (1) studies containing at least one executive function measure; (2) participants were over the age of three. Data extraction: Data extraction and quality assessment were performed independently by two authors. We used a shifting unit-of-analysis approach and pooled data using a random effects model. Results: The search yielded 61,217 results. Twenty-eight studies met criteria. A total of 7789 people with CHD were compared with 8187 healthy controls. We found the following standardised mean differences: −0.628 (−0.726, −0.531) for cognitive flexibility and set shifting, −0.469 (−0.606, −0.333) for inhibition, −0.369 (−0.466, −0.273) for working memory, −0.334 (−0.546, −0.121) for planning/problem solving, −0.361 (−0.576, −0.147) for summary measures, and −0.444 (−0.614, −0.274) for reporter-based measures (p < 0.001). Limitations: Our analysis consisted of cross-sectional and observational studies. We could not quantify the effect of collinearity. Conclusions: Individuals with CHD appear to have at least moderate deficits in executive functions. Given the growing population of people with CHD, more attention should be devoted to identifying executive dysfunction in this vulnerable group.
