Abstract Background Although many studies have demonstrated the commodity of psoriasis with migraine and indicated that they may have similar susceptibility genes and pathophysiologic mechanism, the clinic association between the migraine and psoriasis remains unclear. Methods We have already searched Pubmed, Embase, and Web of Science for case–control, cross-sectional, or cohort studies, and extract rate, odds or risk of migraine in subjects with psoriasis or without psoriasis. Using defined inclusion and exclusion criteria, finally include nine studies. Pooling of the suitable data was applied when necessary. Results Five cross-sectional studies included 6355 psoriasis patients and 934413 controls, migraine highly occurred in psoriasis patient (pooled OR 1.64; 95% confidence interval [1.28; 2.11]). In addition, with 4375 psoriasis patients provided, the rate of migraine occurred in psoriasis patient (pooled rate 0.21; 95% confidence interval [0.13; 0.35]). Conclusion Migraine and psoriasis present a clear co-occurrence and similar pathophysiologic mechanism, which lead to the assumption that the two diseases might be linked. Screening and selection of proper assessment of migraine among psoriasis patients are warranted and needed.

Abstract Background. Parental separation is a very common childhood adversity. The association between other adverse childhood experiences and an increased risk of psychosis has been reported. However, the evidence on the risk of psychosis for children of separated parents is limited. In this systematic review, cohort, case–control, and cross-sectional studies, comparing the risk of psychotic disorders for people with and without separated parents, were searched, critically appraised, and summarized. Methods. Studies were searched in PubMed, EMBASE, PsycINFO, and the Web of Science, from database inception to September 2019. A meta-analysis, using random-effects models, was undertaken to obtain pooled estimates of the risk of psychosis among participants with separated parents. Results. Twelve studies, with 305,652 participants from 22 countries, were included in the review. A significantly increased risk of psychosis for those with separated parents was observed, with a pooled odds ratio: 1.53 (95% confidence interval [CI]: 1.29–1.76), p < 0.001. The association remained significant when cohort, case–control, and cross-sectional studies were analyzed separately. The five cohort studies included in this review showed and increased risk of psychosis with odds ratio: 1.47 (95% CI: 1.26–1.69), p < 0.001. Conclusions. Parental separation is a common childhood adversity associated with an increased risk of psychosis. Although the risk for an individual child of separated parents is still low, given the high proportion of couple that separate, the increased rates of psychosis may be substantial in the population. Further studies on the risk of psychosis in those with separated parents, and the explanatory factors for this association, are required.

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.

Abstract Background: ABO gene polymorphisms have been reported to be associated with the risk of multiple cancers and cardiocerebrovascular disease s. However, the results remained controversial. In this study, we conducted a systematic review and meta-analysis to clarify the association between two SNPs (rs505922 and rs657152) in ABO gene and cancers/ cardiocerebrovascular disease s. Method: All eligible case-control studies come from PubMed, Embase and Web of Science up to Jan. 1, 2019. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the corresponding associations. Sensitivity analysis, publication bias assessment, and heterogeneity test were performed using STATA 12.0. Results : A total of nineteen articles involving twenty-two case-control populations were included according to inclusion and exclusion criteria. Twelve populations (20,820 cases and 27,837 controls) were used to evaluate the relationship between rs505922 and overall cancers and nine populations (22,275 cases and 71,549 controls) were included to assess the association between rs505922 and cardiocerebrovascular diseases. The results showed a significant association between the rs505922 polymorphism and cancers (CvsT: OR=1.13, 95%CI=1.05-1.22, P =0.001), and cardiocerebrovascular diseases (OR=1.36, 95%CI=1.19-1.57, P <0.001). Five populations (8,660 cases and 10,618 controls) were included to evaluate association between rs657152 and cancers and five populations (8,105 cases and 6,712 controls) were included to estimate the relationship between rs657152 and cardiocerebrovascular diseases. The result of meta-analysis reveals that rs657152 was significantly associated with cancers (OR=1.18, 95%CI=1.13-1.23, P <0.001) and cardiocerebrovascular diseases (OR=1.54, 95%CI=1.24-1.92, P <0.001). Conclusion: Our study suggested that ABO polymorphisms might serve as a risk factor of pancreatic cancers and cardiocerebrovascular diseases.

AbstractObjectiveEpidemiological investigations evaluating the association of dietary Ca intake with metabolic syndrome (MetS) risk have yielded controversial results. Therefore, a meta-analysis was conducted to quantitatively summarize the association between dietary Ca intake and the risk of MetS.DesignPubMed, Embase and Web of Science were searched for relevant articles published up to October 2018. The pooled OR and 95 % CI were calculated with a random-effects model.SettingMeta-analysis.ParticipantsNine cross-sectional studies.ResultsA total of nine articles with fifteen studies for dietary Ca intake were finally included in the meta-analysis. The combined OR with 95 % CI of MetS for the highest v. lowest category of dietary Ca intake was 0·80 (95 % CI 0·70, 0·91). For dose–response analysis, a non-linear relationship was found between dietary intake of Ca and risk of MetS (Pnon-linearity<0·001). The threshold for dietary Ca intake was 280 mg/d (OR=0·87; 95 % CI 0·82, 0·93), reducing the risk of MetS by 13 %.ConclusionsThe present meta-analysis suggests that dietary Ca intake might reduce the risk of MetS, which needs to be further confirmed by larger prospective cohort studies.

The Relationship

The association of Helicobacter pylori (H. pylori) infection with functional dyspepsia has been well studied. However, the data on the relationship between H. pylori infection and irritable bowel syndrome (IBS) are conflicting. This study aims to elucidate the association between H. pylori infection and IBS. PubMed, Cochrane Library, CINAHL and SCOPUS databases were searched to identify eligible English articles published up to December 2019. Cross-sectional studies, case–control studies and cohort studies reporting both prevalence of H. pylori infection and IBS were selected for the detailed review. The pooled odds ratio (ORs) and their 95% confidence interval (CI) were calculated. A total of 7269 individuals in four cross-sectional studies and six case-control studies were included. The prevalence of H. pylori infection ranged from 12.8% to 73.4% in the control group, and 9.7% to 72.1% in the IBS group. The combined OR for H. pylori infection was 1.10 (95% CI: 0.93–1.29, I2: 37.5%). In a subgroup analysis of IBS defined according to Rome criteria, the OR for H. pylori infection was 1.10 (95% CI: 0.93–1.30, I2 = 31.7%). In this meta-analysis, H. pylori infection was not significantly associated with IBS. Well-designed studies are needed to identify the relationship between H. pylori infection and IBS.

Objectives. The study aimed to confirm the association between androgenetic alopecia (AGA) and Metabolic Syndrome (MetS). It also aimed to determine if early-onset AGA among males and AGA among females increases the risk of developing MetS, and if severity of AGA increases the odds of developing MetS. Methods. Observational studies from electronic databases were selected by the consensus of three independent review authors. The Newcastle-Ottawa Scale for assessing the quality of non-randomized studies in meta-analysis was used. Statistical analyses were accomplished using Review Manager software. Results. A total of 11 case-control studies, one prospective cohort study, and five cross-sectional studies were selected. In the meta-analysis of ten case-control studies and three cross-sectional studies (3840 participants), AGA was significantly correlated with MetS (OR 2.59, 95% CI 1.51 to 4.44; p<0.0005). Early-onset AGA among males (<35 years old) showed significant association (OR 3.69, 95% CI 2.15 to 6.33; p<0.00001). AGA among females also increased the odds of developing MetS (OR 5.59, 95% CI 2.06 to 15.12; p<0.0007). Moderate to severe AGA in males, Norwood-Hamilton IV or higher, was also significant (OR 1.65, 95% CI 1.12 to 2.42; p=0.01). The same trend was noted for females with Ludwig II and III (OR 5.82, 95% CI 2.54 to 13.34; p<0.00001). Conclusion. Although the pathophysiology still remains under investigation, the present study points to an association between AGA and MetS. It can be used as a marker to identify patients who should be screened for MetS and managed accordingly.

IntroductionChronic obstructive pulmonary disease (COPD) is a major and growing cause of morbidity and mortality worldwide. The global prevalence of COPD is growing faster in women than in men. Women are often exposed to indoor pollutants produced by biomass fuels burning during household activities.MethodsWe conducted a meta-analysis to establish the association between COPD and exposure to biomass smoke in women.Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched MEDLINE and Scopus databases in 31December 2016, with the terms: “wood”, “charcoal”, “biomass”, “solid fuels”, “organic fuel”, “biofuel”, “female”, “women”, “COPD”, “chronic bronchitis”, “emphysema”, “chronic obstructive pulmonary disease”. Studies were eligible if they were case–control or cross-sectional studies involving exposure to indoor biomass smoke, conducted at any time and in any geographic location. Fixed-effects or random-effects meta-analysis was used to generate pooled OR.Results24 studies were included: 5 case–control studies and 19 cross-sectional studies. Biomass-exposed individuals were 1.38 times more likely to be diagnosed with COPD than non-exposed (OR 1.38, 95% CI 1.28 to 1.57).Spirometry-diagnosed COPD studies failed to show a significant association (OR 1.20, 95% CI 0.99 to 1.40). Nevertheless, the summary estimate of OR for chronic bronchitis (CB) was significant (OR 2.11, 95% CI 1.70 to 2.52). The pooled OR for cross-sectional studies and case–control studies were respectively 1.82 (95% CI 1.54 to 2.10) and 1.05 (95% CI 0.81 to 1.30). Significant association was found between COPD and biomass smoke exposure for women living as well in rural as in urban areas.ConclusionsThis study showed that biomass smoke exposure is associated with COPD in rural and urban women.In many developing countries, modern fuels are more and more used alongside traditional ones, mainly in urban area. Data are needed to further explore the benefit of the use of mixed fuels for cooking on respiratory health, particularly on COPD reduction.

ABSTRACT Although several studies have investigated the association between Internet use and odds of overweight and obesity, results are inconsistent. This systematic review and meta-analysis was performed to summarize evidence on the association between Internet use and odds of overweight and obesity. A systematic literature search was conducted in PubMed/Medline, Web of Science, Scopus, and Google Scholar up to February 2019 to identify relevant publications. Finally, 9 cross-sectional studies were considered in this systematic review and meta-analysis. Combining 11 effect sizes from 9 studies, we found a significant, positive association between the highest Internet use, compared to the lowest (ranged from ≥5 h/d to no use among studies), and odds of overweight and obesity (OR: 1.47; 95% CI: 1.21–1.78; I2, 69.6%; P < 0.001), such that Internet users had 47% greater odds of being overweight or obese. We also observed a significant, positive association between the highest Internet use, compared to the lowest (ranged from ≥5 h/d to no use among studies), and overweight/obesity (OR: 1.15; 95% CI: 1.06–1.25; I2, 0.0%; P = 0.426), obesity (OR: 2.58; 95% CI: 1.88–3.54; I2, 0.0%; P = 0.637), and overweight (OR: 1.38; 95% CI: 1.16–1.64; I2, 13.1%; P = 0.330). A linear dose-response meta-analysis revealed that each additional 1 h/d of Internet use was associated with 8% increased odds of overweight and obesity (OR: 1.08; 95% CI: 1.05–1.11; I2, 3.8%; P = 0.403). Findings of this systematic review and meta-analysis indicated that Internet use was positively associated with increased odds of being overweight and obese.

There is accumulating evidence of the neurological and neuropsychiatric features of infection with SARS-CoV-2. In this systematic review and meta-analysis, we aimed to describe the characteristics of the early literature and estimate point prevalences for neurological and neuropsychiatric manifestations. We searched MEDLINE, Embase, PsycINFO and CINAHL up to 18 July 2020 for randomised controlled trials, cohort studies, case-control studies, cross-sectional studies and case series. Studies reporting prevalences of neurological or neuropsychiatric symptoms were synthesised into meta-analyses to estimate pooled prevalence. 13 292 records were screened by at least two authors to identify 215 included studies, of which there were 37 cohort studies, 15 case-control studies, 80 cross-sectional studies and 83 case series from 30 countries. 147 studies were included in the meta-analysis. The symptoms with the highest prevalence were anosmia (43.1% (95% CI 35.2% to 51.3%), n=15 975, 63 studies), weakness (40.0% (95% CI 27.9% to 53.5%), n=221, 3 studies), fatigue (37.8% (95% CI 31.6% to 44.4%), n=21 101, 67 studies), dysgeusia (37.2% (95% CI 29.8% to 45.3%), n=13 686, 52 studies), myalgia (25.1% (95% CI 19.8% to 31.3%), n=66 268, 76 studies), depression (23.0% (95% CI 11.8% to 40.2%), n=43 128, 10 studies), headache (20.7% (95% CI 16.1% to 26.1%), n=64 613, 84 studies), anxiety (15.9% (5.6% to 37.7%), n=42 566, 9 studies) and altered mental status (8.2% (95% CI 4.4% to 14.8%), n=49 326, 19 studies). Heterogeneity for most clinical manifestations was high. Neurological and neuropsychiatric symptoms of COVID-19 in the pandemic’s early phase are varied and common. The neurological and psychiatric academic communities should develop systems to facilitate high-quality methodologies, including more rapid examination of the longitudinal course of neuropsychiatric complications of newly emerging diseases and their relationship to neuroimaging and inflammatory biomarkers.

Abstract Background: ABO gene polymorphisms have been reported to be associated with the risk of multiple cancers and cardiocerebrovascular diseases. However, the results remained controversial. In this study, we conducted a systematic review and meta-analysis to clarify the association between two SNPs (rs505922 and rs657152) in ABO gene and cancers/cardiocerebrovascular diseases. Method: All eligible case-control studies come from PubMed, Embase and Web of Science up to Jan. 1, 2019. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the corresponding associations. Sensitivity analysis, publication bias assessment, and heterogeneity test were performed using STATA 12.0. Results: A total of eighteen articles involving twenty-nine case-control populations were included according to inclusion and exclusion criteria. Eleven populations (16,929 cases and 23,941 controls) were used to evaluate the relationship between rs505922 and overall cancers and nine populations (22,275 cases and 71,549 controls) were included to assess the association between rs505922 and cardiocerebrovascular diseases. The results showed a significant association between the rs505922 polymorphism and cancers (CvsT: OR=1.13, 95% CI=1.04-1.22, P=0.003), and cardiocerebrovascular diseases (OR=1.36, 95%CI=1.19-1.57, P<0.001). Four populations (5,158 cases and 7,021 controls) were included to evaluate association between rs657152 and cancers and five populations (8,105 cases and 6,712 controls) were included to estimate the relationship between rs657152 and cardiocerebrovascular diseases. The result of meta-analysis reveals that rs657152 was significantly associated with cancers (OR=1.16, 95%CI=1.09-1.24, P<0.001) and cardiocerebrovascular diseases (OR=1.54, 95%CI=1.24-1.92, P<0.001). Conclusion: Our study suggested that ABO polymorphisms may serve as a risk factor of cancers and cardiocerebrovascular diseases.
