Abstract Background findings on association of Toxoplasmosis and suicide is contradictory. This paper aimed to resolve this uncertainty with help of Meta-analysis. Methods using keywords include “Toxoplasmosis” and “suicide” and the relayed synonyms in international databases such as ISI, Medline and Scopus, we found the relevant studies. The eligible studies included into Meta-analysis phase. Random effect approach was used to combine the results. Results out of 150 initial studies, 16 were included into meta-analysis. Odds of suicide in person with toxoplasmosis was 47% (OR: 1.47, 95%CI; 1.20 to 1.79) higher than of that without toxoplasmosis. Test for publication bias was not statistically significant, which indicate absence of likely publication bias. Conclusion This study confirm which toxoplasmosis is a potential risk factor for suicide. To reduce cases of suicide attributable to Toxoplasmosis, it deserving the measures to prevent and control of transmission of toxoplasmosis should be taken.

Abstract Background The probability of developing invasive cutaneous malignant melanoma (CMM) is higher in women than in men up until the age of 49. Several studies investigated the association between hormonal factors and CMM. The aim of this systematic review and meta-analysis is to summarize the evidence on the association between Oral Contraceptives (OC) and the risk of CMM. Methods This review and meta-analysis follow the PRISMA guidelines. A systematic literature search was conducted on Medline and Web of Science until December 2019. Studies were eligible if reported a risk estimate for the association between OC and CMM. Heterogeneity testing was performed using Cochran's Q and I2 statistics. Publication bias was assessed by Egger's test and Begg's test. Meta-analysis was performed using random effect model. Results The results of the pooled analysis of all 32 studies showed no significant association between OC and the risk of CMM (OR 1.02; 95% CI 0.94-1.11; I2=39.32%, p = 0.013). The stratified analyses by study design found no significant association between OC and the risk of CMM neither in the 18 case-control studies (OR 1.02; 95% CI 0.87-1.21; I2=56.91%, p = 0.002) nor in the 14 cohort studies (OR 1.04; 95% CI 0.98-1.11; I2=0.00%, p = 0.557). No significant publication bias could be detected by Egger's test or Begg's test. Conclusions This meta-analysis of available literature suggests no significant association between OC and the risk of developing CMM. Further investigations are needed to evaluate the possible relationship of OC use and other hormonal factors potentially contributing to the increased risk of CMM in women during their reproductive years. Key messages Oral contraceptives (OC) do not significantly contribute to the risk of Cutaneous Malignant Melanoma (CMM). Further studies are needed to investigate the potential role of other hormonal factors in the increased probability of developing CMM in women during their reproductive years.

Abstract Background This systematic review and meta-analysis searched, retrieved and synthesized the evidence as to whether preoperative esophagogastroduodenoscopy (p-EGD) should be routine before bariatric surgery (BS). Methods Databases searched for retrospective, prospective, and randomized (RCT) or quasi-RCT studies (01 January 2000–30 April 2019) of outcomes of routine p-EGD before BS. STROBE checklist assessed the quality of the studies. P-EGD findings were categorized: Group 0 (no abnormal findings); Group 1 (abnormal findings that do not necessitate changing the surgical approach or postponing surgery); Group 2 (abnormal findings that change the surgical approach or postpone surgery); and Group 3 (findings that signify absolute contraindications to surgery). We assessed data heterogeneity and publication bias. Random effect model was used. Results Twenty-five eligible studies were included (10,685 patients). Studies were heterogeneous, and there was publication bias. Group 0 comprised 5424 patients (56%, 95% CI: 45–67%); Group 1, 2064 patients (26%, 95% CI: 23–50%); Group 2, 1351 patients (16%, 95% CI: 11–21%); and Group 3 included 31 patients (0.4%, 95% CI: 0–1%). Conclusion For 82% of patients, routine p-EGD did not change surgical plan/ postpone surgery. For 16% of patients, p-EGD findings necessitated changing the surgical approach/ postponing surgery, but the proportion of postponements due to medical treatment of H Pylori as opposed to “necessary” substantial change in surgical approach is unclear. For 0.4% patients, p-EGD findings signified absolute contraindication to surgery. These findings invite a revisit to whether p-EGD should be routine before BS, and whether it is judicious to expose many obese patients to an invasive procedure that has potential risk and insufficient evidence of effectiveness. Further justification is required.

Abstract Background. Severe coronavirus disease-19 (COVID-19) presents with progressive dyspnea, which results from acute lung inflammatory edema leading to hypoxia. As with other infectious diseases that affect the respiratory tract, asthma has been cited as a potential risk factor for severe COVID-19. However, conflicting results have been published over the last few months and the putative association between these two diseases is still unproven. Methods. Here, we systematically reviewed all reports on COVID-19 published since its emergence in December 2019 to June 30, 2020, looking into the description of asthma as a premorbid condition, which could indicate its potential involvement in disease progression. Results. We found 372 articles describing the underlying diseases of 161,271 patients diagnosed with COVID-19. Asthma was reported as a premorbid condition in only 2,623 patients accounting for 1.6% of all patients. Conclusions. As the global prevalence of asthma is 4.4%, we conclude that either asthma is not a premorbid condition that contributes to the development of COVID-19 or clinicians and researchers are not accurately describing the premorbidities in COVID-19 patients.

Abstract Background Global data on stroke mortality remained to be sparse. In light of this, we aimed to conduct a Meta-analysis and systematic review of observational studies to estimate the mortality of stroke and to identify risk factors that predispose patients for stroke-related death.Methods This study was conducted based on the Meta-Analyses of Observational Studies in Epidemiology (MOOSE) guidelines. Overall mortality, in-hospital and 30- day mortality due to stroke were the primary outcome measures of the study. The meta-analysis was performed using Stata (Version 14, Stata Corp, College Station, Texas). Random-effect models were used for estimating pooled effects.Findings Overall, thirty two studies assessed overall mortality due to stroke. A total number of 2,885, 126 patients were recruited for the study. Pooled estimate indicated that the overall mortality of stroke was reported to be 20% (19%-22%). Whereas, the 30-day and In-hospital mortality were found to be 18% (16%-20%) and 16% (16%-19%), respectively. A subgroup analysis revealed that Africa registered the highest stroke-related death 29% (23%-36%). Hypertension was found to be an important risk factor for mortality secondary to stroke 61.9% (52.8%-71.1%).Conclusion Overall mortality of stroke was estimated to be twenty percent. The burden of stroke mortality was prominent in Africa region. Hypertension remained to be an independent risk factor for stroke mortality. Mortality of stroke can be minimized by establishing stroke centers that promptly deliver emergency management of stroke event.

Pooled Prevalence

Human Papilloma Virus (hpv) infection causes different cancer diseases. Cervical cancer is the most common hpv related disease. hpv infection also causes cancer of anus, vulva, vagina, penis, skin, bladder, prostate, breast, oral and others because the hpv virus is epithelium-tropic. But the association of hpv infection other than cervical cancer, for example breast cancer, bladder cancer, prostate cancer etc is still inconclusive. Thus, the objective of this review was to collect published information on hpv infection other than cervix to explore the pooled prevalence of hpv infection as well as related types of cancers.  Publish research articles of hpv infection and cancer risks other than cervical cancer were systematically searched through Internet. The preferred reporting items for systematic review and meta-analysis guidelines were followed. Joanna Brigg’s Institute Meta-Analysis of Statistics Assessment and Review Instrument (jbi-mastari) adapted for cross sectional/case control study design was used for quality assessment of each individual study. A total of 22 studies were extracted and analyzed using stata 14. The random effect model was used to estimate the pooled prevalence; whereas subgroup analysis and meta-regression was performed to identify the probable source of heterogeneity. Both Egger’s and Begg’s tests were used to check publication bias.  The totals of 486 studies were retrieved and 22 studies were included in this meta- analysis. The meta-analysis result showed that the pooled prevalence of hpv infection other than cervix was 34.36% (95% CI: 23.75, 44.97) with severe heterogeneity (I2 = 99.5%; p<0.001) with no publication bias. The highest pooled prevalence of hpv infection other than cervix was related to genital cancer which is 58.63% (95% CI: 51.86, 65.39), followed by oral cancer (47.15% with 95% CI: 19.67, 74.63). Although cervical cancer is primarily hpv induced cancer which well articulated with so many researches, other cancer types (based on the location of the hpv infection) are also increasing across the world based on this systematic and meta-analysis study. hpv infection increases the risk of developing cancers other than cervical cancer.
