Toxoplasmosis is a serious zoonotic disease that can lead to abortion and congenital disorders and has a widespread global distribution in humans and animals. The objective of this review was to investigate the incidence of toxoplasmosis in Iranian neonates in order to obtain a comprehensive assessment of the overall situation of the disease for use in developing future interventions. Original studies investigating the incidence of Toxoplasma gondii infections in Iranian neonates were systematically searched in a number of English-language and Persian-language electronic databases. The search process resulted in the inclusion of a total of 11 studies in the systematic review, 10 of which were entered into the meta-analysis. The reviewed articles included 2,230 Iranian neonates investigated through January 1, 2018. Based on the retrieved studies, the overall weighted incidence rates of toxoplasmosis in the Iranian neonatal population and neonates with suspected congenital toxoplasmosis were estimated to be 0.64% (95% confidence interval [CI], 0.31 to 1.09) and 4.10% (95% CI, 2.68 to 5.77), respectively, using a fixed-effects model. The findings of the reviewed studies demonstrate that the incidence of toxoplasmosis is high in Iranian neonates. Accordingly, it can be concluded that toxoplasmosis is a serious public health concern that has been ignored by the Ministry of Health. Therefore, it is essential to perform further studies, in addition to implementing screening and detection programs, using standardized methods to estimate the incidence of toxoplasmosis in Iran and to determine its associated risk factors.

The Relationship

Context Infant colic is a common and distressing disorder of early infancy. Its etiology is unknown, making treatment challenging. Several articles have suggested a link to migraine. Objective The objective of this article was to perform a systematic review and, if appropriate, a meta-analysis of the studies on the relationship between infant colic and migraine. Data sources Studies were identified by searching PubMed and ScienceDirect and by hand-searching references and conference proceedings. Study selection For the primary analysis, studies specifically designed to measure the association between colic and migraine were included. For the secondary analysis, studies that collected data on colic and migraine but were designed for another primary research question were also included. Data extraction Data were abstracted from the original studies, through communication with study authors, or both. Two authors independently abstracted data. Main outcomes and measures The main outcome measure was the association between infant colic and migraine using both a fixed-effects model and a more conservative random-effects model. Results Three studies were included in the primary analysis; the odds ratio for the association between migraine and infant colic was 6.5 (4.6–8.9, p < 0.001) for the fixed-effects model and 5.6 (3.3–9.5, p = 0.004) for the random-effects model. In a sensitivity analysis wherein the study with the largest effect size was removed, the odds ratio was 3.6 (95% CI 1.7–7.6, p = 0.001) for both the fixed-effects model and random-effects model. Conclusions In this meta-analysis, infant colic was associated with increased odds of migraine. If infant colic is a migrainous disorder, this would have important implications for treatment. The main limitation of this meta-analysis was the relatively small number of studies included.

Introduction and objectivesSurgical site infections (SSIs) represent a common and serious complication of all surgical interventions. Microorganisms are able to colonise sutures that are implanted in the skin, which is a causative factor of SSIs. Triclosan-coated sutures are antibacterial sutures aimed at reducing SSIs. Our objective is to update the existing literature by systematically reviewing available evidence to assess the effectiveness of triclosan-coated sutures in the prevention of SSIs.MethodsA systematic review of EMBASE, MEDLINE, AMED (Allied and complementary medicine database) and CENTRAL was performed to identify full text randomised controlled trials (RCTs) on 31 May 2019.InterventionTriclosan-coated sutures versus non-triclosan-coated sutures.Primary outcomeOur primary outcome was the development of SSIs at 30 days postoperatively. A meta-analysis was performed using a fixed-effects model.ResultsTwenty-five RCTs were included involving 11 957 participants. Triclosan-coated sutures were used in 6008 participants and non triclosan-coated sutures were used in 5949. Triclosan-coated sutures significantly reduced the risk of SSIs at 30 days (relative risk 0.73, 95% CI 0.65 to 0.82). Further sensitivity analysis demonstrated that triclosan-coated sutures significantly reduced the risk of SSIs in both clean and contaminated surgery.ConclusionTriclosan-coated sutures have been shown to significantly reduced the risk of SSIs when compared with standard sutures. This is in agreement with previous work in this area. This study represented the largest review to date in this area. This moderate quality evidence recommends the use of triclosan-coated sutures in order to reduce the risk of SSIs particularly in clean and contaminated surgical procedures.PROSPERO registration numberCRD42014014856

The Difference

Background: Toenail onychomycosis is a challenge for clinicians to treat, and this challenge is compounded by conflicting information in the medical literature concerning the efficacy of the two principal agents used in its treatment: Terbinafine and itraconazole. Objective: The purpose of this meta-analysis is to compare the efficacy of terbinafine with that of itraconazole in the treatment of toenail onychomycosis caused by dermatophytes. Methods: A Medline search was performed for all English language publications from 1966 to June 1999 on the use of terbinafine and itraconazole in the treatment of toenail onychomycosis. Included were randomized studies in which subjects received no less than 3 months (or cycles) and no more than 4 months (or cycles) of either terbinafine or itraconazole. Data were abstracted and statistical analyses (random effects model, fixed effects model, and Peto's method) were applied. Results: Thirteen studies were included from the original literature review of 1636 total referenced reports; four studies did not fulfill our inclusion or exclusion criteria. The primary analysis of six studies directly comparing terbinafine to itraconazole resulted in an odds ratio ranging from 1.8 (95% CI = 1.8, 2.8) to 2.9 (1.9, 4.1). The secondary analysis of three studies comparing either itraconazole or terbinafine to placebo estimated an odds ratio of 1.1–1.7. The former shows that terbinafine is 80%–190% more likely to result in mycologic cure than is itraconazole; the latter demonstrates a 10%–70% greater likelihood. The difference between the relative efficacies of terbinafine and itraconazole was highly statistically significant ( p < 0.0001). Conclusion: Meta-analysis of the published worldwide literature finds that terbinafine is significantly more effective than itraconazole at achieving mycologic cure of toenail onychomycosis.

Q Statistic

Abstract Background: The pandemic of COVID-19 posed a challenge to global healthcare. The mortality rates of severe cases range from 8.1% to 31.8%, and it is particularly important to identify risk factors that aggravate the disease.Methods: We performed a systematic review of the literature with meta-analysis, using 7 databases to assess clinical characteristics, comorbidities and complications in severe and non-severe patients with COVID-19. All the observational studies were included. We performed a random or fixed effects model meta-analysis to calculate the pooled proportion and 95% CI. Measure of heterogeneity was estimated by Cochran’s Q statistic, I2 index and P value.Results: 4881 cases from 25 studies related to COVID-19 were included. The most prevalent comorbidity was hypertension (severe: 33.4%, 95% CI: 25.4% - 41.4%; non-severe 21.6%, 95% CI: 9.9% - 33.3%), followed by diabetes (severe: 14.4%, 95% CI: 11.5% - 17.3%; non-severe: 8.5%, 95% CI: 6.1% - 11.0%). The prevalence of ARDS, AKI and shock were all higher in severe cases, with 41.1% (95% CI: 14.1% - 68.2%), 16.4% (95% CI: 3.4% - 29.5%) and 19.9% (95% CI: 5.5% - 34.4%), rather than 3.0% (95% CI: 0.6% - 5.5%), 2.2% (95% CI: 0.1% - 4.2%) and 4.1% (95% CI -4.8% - 13.1%) in non-severe patients, respectively. The death rate was higher in severe cases (30.3%, 95% CI: 13.8% - 46.8%) than non-severe cases (1.5%, 95% CI: 0.1% - 2.8%).Conclusions: Hypertension, diabetes and cardiovascular diseases may be risk factors for COVID-19 patients to develop into severe cases.

e12530 Background: Palbociclib is an oral small-molecule inhibitor of cyclin-dependent kinases 4 and 6 and has improved the progression-free survival of estrogen receptor positive, metastatic breast cancer (MBC). Its application in other cancers is also undergoing clinical evaluation. Neutropenia, especially high grade (grade 3 or 4), is one of the major side-effects of palbociclib, and the incidence was reported too vary in different studies. In order to better understand the overall risk of palbociclib associated neutropenia, we conducted a systematic review and meta-analysis. Methods: We conducted a systematic literature search (including Medline, Web of Science to November, 2016 and abstracts presented at the ASCO annual meetings from 2009 to 2016). Eligible studies include prospective clinical trials of patients with cancer treated with palbociclib on a 125mg daily 3/4 week schedule and have available data on neutropenia. The incidence and relative risk (RR) of neutropenia were calculated using a random-effects or fixed-effects model, depending on the heterogeneity of the included studies. Results: Eight studies published between 2012 and 2016 included a total of 1515 patients with cancer were eligible for analysis. For patients treated with palbociclib, the overall incidence of all-grade and high grade neutropenia were 77.4% (95% CI 70.9-82.8%) and 60.9% (57.8–63.8%), respectively. Surprisingly, the incidence of neutropenia was significantly different between MBC patients and non-MBC patients (all grade: RR 1.26 [95% CI 1.01–1.56], p = 0.041; high-grade: RR 1.57 [1.23–2.00], p = 0.000) who received palbociclib. Palbociclib was associated with a significantly increased risk of all-grade neutropenia in patients with cancer with an RR of 15.03 (10.17–22.21, p < 0.001) compared with controls. Conclusions: Patients with cancer who received palbociclib have a significant risk of developing neutropenia, especially MBC patients. It is strongly recommended to monitor these patients who are treated with palbociclib to adjust dose, treatment intervals, and avoid infections.

Abstract Purpose Laparoscopic intraperitoneal onlay mesh in hernia repair can result in adhesions leading to intestinal obstruction and fistulation. The aim of this systematic review is to compare the effects of mesh coatings reducing the tissue-to-mesh adhesion in animal studies. Methods Pubmed and Embase were systematically searched. Animal experiments comparing intraperitoneally placed meshes with coatings were eligible for inclusion. Only studies with comparable follow-up, measurements, and species were included for data pooling and subsequent meta-analysis. Results A total of 131 articles met inclusion criteria, with four studies integrated into one comparison and five studies integrated into another comparison. Compared to uncoated polypropylene (PP) mesh, PP mesh coated with hyaluronic acid/carboxymethyl cellulose (HA/CMC) showed significantly reduced adhesion formation at follow-up of 4 weeks measured with adhesion score of extent (random effects model, mean difference,−  0.96, 95% CI − 1.32 to − 0.61, P < 0.001, I2 = 23%; fixed effects model, mean difference,− 0.94, 95% CI − 1.25 to − 0.63, P < 0.001, I2 = 23%). Compared to PP mesh, polyester mesh coated with collagen (PC mesh) showed no significant difference at follow-up of 4 weeks regarding percentage of adhesion-area on a mesh, using random effects model (mean difference − 11.69, 95% CI − 44.14 to 20.76, P = 0.48, I2 = 92%). However, this result differed using fixed effects model (mean difference − 25.55, 95% CI − 33.70 to − 7.40, P < 0.001, I2 = 92%). Conclusion HA/CMC coating reduces adhesion formation to PP mesh effectively at a follow-up of 4 weeks, while the anti-adhesive properties of PC mesh are inclusive comparing all study data.

ObjectiveThe aim of this study was to compare the incidence of ovarian metastasis (OM) in adenocarcinoma (ADC) and squamous cell carcinoma (SCC) in early-stage cervical cancer and evaluate the safety of ovarian preservation in early-stage ADC.MethodsTo perform a meta-analysis to compare the incidence of OM between early-stage ADC and SCC, we searched PubMed, EMBASE, and Cochrane for observational studies that compared it with pathological evidence after radical hysterectomy and oophorectomy. Odds ratios with 95% confidence intervals were calculated with a fixed effects model. We also found a few articles evaluating the oncological prognosis of patients with ovarian preservation to perform a systematic review.ResultsA total of 5 studies were included in the meta-analyses. The incidence of OM of patients with early-stage ADC and SCC were 2% and 0.4%, respectively (odds ratio, 5.27; 95% confidence interval, 2.14–13.45). In 1427 patients with ADC or SCC of the cervix FIGO stage (CIS-IIA) who underwent hysterectomy, no ovarian recurrences were observed after unilateral or bilateral ovarian preservation in ADC patients in the follow-up (30–68 months); however, 15 patients with SCC developed pelvic recurrence.ConclusionsAlthough the incidence of OM was higher in early-stage ADC than SCC according to ovarian pathology, it might be relatively safe to perform ovarian preservation with early-stage ADC because of low ovarian recurrence rate in short-term follow-ups.

Background: Lung cancer is an important complication of combined pulmonary fibrosis and emphysema (CPFE). Whether the risk of lung cancer is higher in CPFE patients with usual interstitial pneumonia (UIP) than those with idiopathic pulmonary fibrosis (IPF) alone, remains controversial. We conducted this systematic review and meta-analysis to evaluate the prevalence of lung cancer in CPFE patients with UIP compared with IPF patients. Methods: We searched the PubMed, Embase, and Cochrane databases for studies that focused on the incidence of lung cancer in CPFE/UIP and IPF groups. We used a fixed-effects model to analyze the odds ratios (ORs) with 95% confidence intervals (CIs) according to data heterogeneity. The cumulative effects based on the publication year and sample size were assessed by cumulative meta-analysis. Results: A total of nine studies with 933 patients, including 374 CPFE patients with UIP, fulfilled the inclusion criteria. Overall, CPFE patients with UIP have a higher risk of lung cancer than those with IPF alone (OR = 2.69; 95% CI: 1.78–4.05). There were increased risks of lung cancer in CPFE/UIP patients with the presence of emphysema (OR = 2.93; 95% CI: 1.79–4.79) or emphysema in ⩾10% of the lung volume (OR = 2.22; 95% CI: 1.06–4.68). Conclusions: Our systematic review and meta-analysis indicated a significantly higher prevalence of lung cancer in CPFE patients with UIP than in patients with IPF alone.
