BACKGROUND: nocardiosis is an opportunistic infectious disease in immunocompromised patients. The most common form of nocardiosis infection in humans is pulmonary nocrdiosis caused by inhaling Nocardia species from the environment. Thus, this study aimed to evaluate the pulmonary nocardiosis in patients with suspected tuberculosis using systematic review and meta-analysis.METHODS: We conducted a systematic search for cross-sectional studies focused on the pulmonary nocardiosis among patients with pulmonary tuberculosis based on the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) published from January 2001 to October 2019. The search was conducted in MEDLINE/PubMed, Web of Science, Scopus, Cochrane Library, Google Scholar, Science Direct databases, and Iranian databases. Medical subject headings (MeSH) and text words were searched: “pulmonary nocardiosis”, “nocardiosis”, OR “nocardial infection”, “pulmonary nocardial infections/agents”, AND “pulmonary tuberculosis”, OR “pulmonary TB”, AND “Iran”. Two of the reviewers enrolled independently articles published in English and Persian languages according to the inclusion and the exclusion criteria. Comprehensive Meta-Analysis software (Version 3.3.070) was used for meta-analysis.RESULTS: Only 4 studies met the eligibility criteria. The pulmonary nocardiosis prevalence varied from 1.7% to 6.7%. The combined prevalence of nocardiosis among patients with suspected pulmonary tuberculosis in Iran was 4.8% (95% CI: 3-7.3, Q=5.8, Z=12.7). No heterogeneity was observed between studies because I2 was 48.3. N. cyriacigeorgica and N. asteroides were reported as the prevalent isolates, respectively.CONCLUSIONS: This review showed in patients suspected TB when they were negative in all diagnosis laboratory tests, nocardiosis cases which be considered.

Abstract Background Diagnosis of fungal co-infections in patients with pulmonary tuberculosis has critical importance. In this review, we aimed to determine the prevalence of candida coinfection in patients with pulmonary tuberculosis.Methods The present systematic review of cross-sectional studies was conducted based on the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) Protocol. Studies published online in English from January 2001 to March 2019 were assessed. Literature search was performed in Web of Science, MEDLINE/PubMed, and Scopus databases using keywords combinations of “pulmonary fungal”, “pulmonary coinfection”, OR “pulmonary mycosis”, “pulmonary fungal infections/agents”, OR “polymicrobial infection”, OR “secondary infection”, OR “mixed infections”, “pulmonary candidiasis”, “fungi coinfection”, “fungal co-colonization”, AND “pulmonary tuberculosis”, OR “pulmonary TB”. Data was analyzed using Comprehensive Meta-Analysis software. Heterogeneity between studies was evaluated by Cochran's Q, and I 2 tests.Results The pooled global prevalence of candida coinfection among patients with pulmonary tuberculosis was 25.7% (95% CI: 23.7-27.9). C. albicans was the most prevalent Candida spp. with a pooled prevalence of 65.8% (95% CI: 54.3-75.7). Risk factors of candida coinfection included smoking, diabetes, advanced age, and low body mass index.Conclusion The present review showed the high rate of candida coinfection among patients suffering from pulmonary tuberculosis. Adequate measures are necessary to early diagnose and treat these infections.

Neighbourhood Socioeconomic Status

ObjectiveLow neighbourhood socioeconomic status (NSES) has been linked to a higher risk of overweight/obesity, irrespective of the individual’s own socioeconomic status. No meta-analysis study has been done on the association. Thus, this study was done to synthesise the existing evidence on the association of NSES with overweight, obesity and body mass index (BMI).DesignSystematic review and meta-analysis.Data sourcesPubMed, Embase, Scopus, Cochrane Library, Web of Sciences and Google Scholar databases were searched for articles published until 25 September 2019.Eligibility criteriaEpidemiological studies, both longitudinal and cross-sectional ones, which examined the link of NSES to overweight, obesity or BMI, were included.Data extraction and synthesisData extraction was done by two reviewers, working independently. The methodological quality of included studies was assessed using the Newcastle-Ottawa Scale for the observational studies. The summary estimates of the relationships of NSES with overweight, obesity and BMI statuses were calculated with random-effects meta-analysis models. Heterogeneity was assessed by Cochran’s Q and I2 statistics. Subgroup analyses were done by age categories, continents, study designs and NSES measures. Publication bias was assessed by visual inspection of funnel plots and Egger’s regression test.ResultA total of 21 observational studies, covering 1 244 438 individuals, were included in this meta-analysis. Low NSES, compared with high NSES, was found to be associated with a 31% higher odds of overweight (pooled OR 1.31, 95% CI 1.16 to 1.47, p<0.001), a 45% higher odds of obesity (pooled OR 1.45, 95% CI 1.21 to 1.74, p<0.001) and a 1.09 kg/m2 increase in mean BMI (pooled beta=1.09, 95% CI 0.67 to 1.50, p<0.001).ConclusionNSES disparity might be contributing to the burden of overweight/obesity. Further studies are warranted, including whether addressing NSES disparity could reduce the risk of overweight/obesity.PROSPERO registration numberCRD42017063889

ABSTRACT Objective: systematic review with a meta-analysis of the prevalence of malaria relapse. Method: it consisted in a search for cross-sectional studies, carried out in three databases, without application of filters. A total of 1,924 articles were identified, selected based on eligibility criteria. The selection was made in pairs from the reading of the titles, abstracts and text. The meta-analysis was performed with a statistical program. Results: a sample of 1,308 patients with malaria, ranging from 70 to 586 patients in the study. Relapse was estimated at 0.47%, with a 95% confidence interval and 99.04% of squared i. In the included studies, the prevalence of relapse ranged from 17.00% to 92.85%. The result of the meta-analysis is considered relevant, despite the heterogeneity. Conclusion: relapse is a phenomenon that can contribute to the maintenance of the endemicity of malaria in the world and to introduce it in non-affected areas. In addition, there is the need for advancement in the production of knowledge regarding this disease, to qualify the research methods on prevalence.

ObjectivesTo carry out meta-analysis and systematic review on the association between soft drinks consumption and asthma prevalence among adults and children.DesignSystematic review and meta-analysis of observational research.Data sourcesMedline, Scopus, ISI Web of Science and the Cochrane Library were searched up to December 2018.Eligibility criteriaWe included observational studies investigating the association between soft drinks consumption (including maternal consumption during pregnancy) and asthma or wheeze.Data extraction and synthesisData were extracted by one author and reviewed independently by two other authors. The most adjusted estimate from each original study was used in the meta-analysis. Meta-analysis was conducted using random-effects model. The quality of studies was assessed using the Newcastle–Ottawa scale and heterogeneity was evaluated using I2statistic.ResultsOf 725 publications originally identified, 19 were included in this systematic review, including 3 cohort studies and 16 cross-sectional studies. Ten articles reported on children up to 18 years, 5 articles on adults (>18 years) and 2 articles on prenatal exposure. In total, 468 836 participants were included, with more than 50 000 asthma cases. Soft drinks consumption was associated with significantly increased odds of asthma in both adults (OR=1.37; 95% CI, 1.23 to 1.52) and children (OR=1.14; 95% CI, 1.06 to 1.21). Prenatal exposure had marginally statistically significant association (OR=1.11; 95% CI, 1.00 to 1.23) with asthma in children. In subgroup analysis for childhood exposure, the association persists for sugar-sweetened soft drinks but not for carbonated drinks.ConclusionOur findings show a positive association between soft drinks consumption and asthma prevalence, mostly from cross-sectional studies. Therefore, more longitudinal research is required to establish causality.

ABSTRACT This systematic review and meta-analysis aimed to explore the association between the Mediterranean dietary pattern and inflammation in older adults. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. A search of the literature was conducted up to June 2020 in 7 electronic databases, namely PubMed, Embase, Web of Science, Scopus, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and ProQuest. The Joanna Briggs Institute Critical Appraisal Checklists and the Newcastle-Ottawa Scale were used to assess the methodological quality. The overall standardized mean difference (SMD) and 95% CIs were estimated in random-effects meta-analyses. Thirteen studies were identified as having acceptable quality and were included in this systematic review: 3 randomized controlled trials (RCTs), 1 quasi-experimental study, 1 cohort study, and 8 cross-sectional studies. The circulating C-reactive protein (CRP) concentration was the most common inflammation indicator used. Results of the meta-analysis on 5 cross-sectional studies revealed a significant inverse association between the Mediterranean dietary pattern and inflammation as assessed by CRP (SMD = −0.26; 95% CI: −0.41, −0.11; P &lt; 0.001). Other studies that investigated a variety of inflammation indicators other than CRP showed mixed results with regard to the relation between the Mediterranean dietary pattern and inflammation in older adults. Our findings suggest that the Mediterranean dietary pattern may be associated with lower inflammation in older adults. However, more long-term RCTs are required to demonstrate the effects of the Mediterranean dietary pattern on multiple inflammation parameters in older adults. The study has been registered on PROSPERO (#CRD42020140145).

Increased Risk

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.

ObjectivesGout, characterised by hyperuricaemia with monosodium urate crystal formation and inflammation, is the most common inflammatory arthritis in adults. Recent studies have found that elevated uric acid levels are related to the occurrence of dementia. We conducted a study to investigate the association between dementia and gout or hyperuricaemia.DesignSystematic review and meta-analysis of cohort studies.Data sourcesStudies were screened from inception to 28 June 2019 by searching Medline, Embase and the Cochrane Library databases.Eligibility criteriaCohort studies comparing the risk of dementia in patients with gout and hyperuricaemia versus non-gout and non-hyperuricaemia controls were enrolled.Data extraction and analysisTwo reviewers separately selected studies and extracted data using the Medical Subject Headings without restriction on languages or countries. The adjusted HRs were pooled using the DerSimonian and Laird random effects model. Sensitivity analyses were conducted to evaluate the stability of the results. Publication bias was evaluated using Egger’s and Begg’s tests. Quality assessment was performed according to the Newcastle-Ottawa Scale.ResultsFour cohort studies that met the inclusion criteria were included in our meta-analysis. We found that gout and hyperuricaemia did not increase the risk of dementia, with a pooled HR of 0.94 (95% CI 0.69 to 1.28), but might decrease the risk of Alzheimer’s disease (AD), with a pooled HR of 0.78 (95% CI 0.64 to 0.95). There was little evidence of publication bias. Quality assessment of the included studies was high (range: 6–8 points).ConclusionsOur study shows that gout and hyperuricaemia do not increase the risk of dementia. However, gout and hyperuricaemia might have a protective effect against AD. Due to the limited number of research articles, more investigations are needed to demonstrate the potential relationship between dementia and gout or hyperuricaemia.
