Project description:COVID-19 is a disease first identified in Wuhan City, Hubei Province, China, in December 2019, causes by a SARS-COV-2 virus infection. By 27 October 2020, 43,921,473 confirmed cases were reported worldwide, with 1,166,389 COVID-19 deaths. Conjunctivitis has been reported in adults and pediatric patients with COVID-19.ObjectiveThe aim of this meta-analysis is to estimate the odd Ratio (ORs) of conjunctivitis in patients with COVID-19.MethodsA systematic review and meta-analysis have been performed using the PubMed and Google Scholar literature search. The ORs of conjunctivitis in adults and pediatric patients is the outcome of this meta-analysis.ResultsThere have been 1041 articles published since the outbreak in December 2019, according to the latest literature. For the meta-analysis, 20 studies with a total of 3383 participants were included. The odds ratio (ORs) of conjunctivitis was 0.01 (95% confidence interval [CI]: 0.00-0.02). No bias has been reported.ConclusionConjunctivitis is the most common ocular manifestations reported in adults. This comprehensive meta-analysis quantifies the existing evidence linking conjunctivitis with COVID-19 and highlights the high percentage of heterogeneity that is shown in the current studies. Finally, it offers a single review article which includes all the current articles available for COVID-19 and conjunctivitis in adults and children.

Project description:We compared circulating miRNA profiles of hospitalized COVID-positive patients (n = 104, 27 with ARDS) and age and gender matched healthy controls (n = 18) to identify miRNA signatures associated with COVID and COVID-induced ARDS. Meta-analysis incorporating data from published studies and our data was performed to identify a set of differentially expressed miRNAs in 1) COVID-positive patients versus healthy controls as well as 2) severe (ARDS+) COVID vs moderate COVID. Gene ontology enrichment analysis of the genes these miRNAs interact with identified terms associated with immune response, such as interferon and interleukin signaling, as well as viral genome activities associated with COVID disease and severity. Additionally, we observed downregulation of a cluster of miRNAs located on chromosome 14 (14q32) among all COVID patients. To predict COVID disease and severity, we developed machine learning models that achieved AUC scores between 0.88–0.93 for predicting disease, and between 0.62–0.81 for predicting severity, even across diverse studies with different sample types (plasma versus serum), collection methods, and library preparations. Our findings provide network and top miRNA feature insights into COVID disease progression and contribute to the development of tools for disease prognosis and management.

Project description:BackgroundThe coronavirus disease 2019 (COVID-19) pandemic continues to cause global havoc posing uncertainty to educational institutions worldwide. Understanding the clinical characteristics of COVID-19 in children is important because of the potential impact on clinical management and public health decisions.MethodsA meta-analysis was conducted for pediatric COVID-19 studies using PubMed and Scopus. It reviewed demographics, co-morbidities, clinical manifestations, laboratory investigations, radiological investigations, treatment, and outcomes. The 95% confidence interval (CI) was utilized.ResultsOut of 3927 articles, 31 articles comprising of 1816 patients were selected from December 2019 to early October 2020 and were defined by 77 variables. Of these studies 58% originated from China and the remainder from North America, Europe and the Middle East. This meta-analysis revealed that 19.2% (CI 13.6%-26.4%) of patients were asymptomatic. Fever (57%, CI 49.7%-64%) and cough (44.1%, CI 38.3%-50.2%) were the most common symptoms. The most frequently encountered white blood count abnormalities were lymphopenia 13.5% (CI 8.2%-21.4%) and leukopenia 12.6% (CI 8.5%-18.3%). Ground glass opacities were the most common radiological finding of children with COVID-19 (35.5%, CI 28.9%-42.7%). Hospitalization rate was 96.3% (CI 92.4%-98.2%) of which 10.8% (CI 4.2%-25.3%) were ICU admissions, and 2.4% (CI 1.7%-3.4%) died.ConclusionThe majority of pediatric patients with COVID-19 were asymptomatic or had mild manifestations. Among hospitalized patients there remains a significant number that require intensive care unit care. Overall across the literature, a considerable level of understanding of COVID-19 in children was reached, yet emerging data related to multisystemic inflammatory syndrome in children should be explored.

Project description:Five cases of non-remitting conjunctivitis turned out to be the sole presenting sign and symptom of COVID-19. These patients tested positive on RT-PCR of naso-pharyngeal swabs and developed no fever, malaise, or respiratory symptoms throughout the course of their illness. They all fully recovered. In the current efforts to fight the spread of this virus, authors want to emphasize that atypical clinical presentations of COVID-19 can occur and a high level of suspicion should be maintained. Ocular involvement and transmission of SARS-CoV-2 should never be overlooked. In fact, conjunctival mucosae are susceptible to respiratory viruses and remain an important point of entry. For this reason, eye protection in the form of goggles or a face shield should be considered essential for all healthcare providers, even when taking care of patients who are not showing typical symptoms of COVID-19.

Project description:BackgroundWith the continued high prevalence of chlamydia worldwide and high risk of transfer from mothers to their infant during delivery, a need for safe and effective therapies for infants who acquire a chlamydial infection remains. We conducted a systematic review and meta-analysis of antibiotic treatments, including oral erythromycin, azithromycin, and trimethoprim, for neonatal chlamydial conjunctivitis.MethodsWe searched Medline, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) from their inception to July 14, 2017. We included randomized and nonrandomized studies that evaluated the effects of erythromycin, azithromycin, or trimethoprim in neonates with chlamydial conjunctivitis. A meta-analysis using a random-effects generic inverse-variance method was performed, and the certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach.ResultsWe found 12 studies (n = 292 neonates) and were able to meta-analyze 7 studies that used erythromycin at a dose of 50 mg/kg body weight per day for 14 days. The clinical and microbiological cure were 96% (95% confidence interval [CI], 94%-100%) and 97% (95% CI, 95%-99%), respectively, and adverse gastrointestinal effects occurred in 14% (95% CI, 1%-28%) of the neonates. The microbiological cure in the study that assessed azithromycin at 20 mg/kg per day were 60% (95% CI, 27%-93%) when it was given in a single dose and 86% (95% CI, 61%-100%) when given in a 3-day course. Two studies reported compliance with treatments, and 1 study reported no pyloric stenosis events. Because of the risk of bias and the few neonates included across the studies, the certainty of evidence is low to very low. No studies assessed trimethoprim.ConclusionsAlthough evidence suggests that erythromycin at 50 mg/kg per day for 14 days results in higher numbers of cure than does azithromycin, compliance and risk of pyloric stenosis related to their use for other infections in neonates will factor into treatment recommendations. More data are needed to compare these treatments directly.

Project description:BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can induce conjunctivitis signs and symptoms. However, limited information is available on their impact on COVID-19 disease phenotype. Quantification of ocular signs/symptoms can provide a rapid, non-invasive proxy for predicting clinical phenotype. Moreover, the existence and entity of conjunctival viral shedding is still debated. This has relevant implications to manage disease spread. The purpose of this study was to investigate conjunctivitis signs and symptoms and their correlation with clinical parameters, conjunctival viral shedding in patients with COVID-19.MethodsFifty-three patients hospitalized between February 25th and September 16th, 2020 at the San Raffaele Hospital, in Milan, Lombardy, Italy with a confirmed diagnosis of SARS-CoV-2 were evaluated. Presence of interstitial pneumonia was confirmed with computed tomography scan imaging. Ocular signs and symptoms, anosmia/ageusia, clinical/laboratory parameters, and reverse transcriptase-polymerase chain reaction (RT-PCR) from nasopharyngeal and conjunctival swabs for COVID-19 virus were analyzed.ResultsForty-six out of 53 patients showed a positive nasopharyngeal swab for SARS-CoV-2 infection at the time of conjunctival evaluation. All the conjunctival swabs were negative. Conjunctivitis symptoms were present in 37% of patients. Physician-assessed ocular signs were detected in 28% of patients. Patients with ocular symptoms or signs tended to be older: 76.8 years (62.4-83.3) vs 57.2 years (48.1-74.0), p = 0.062 and had a longer hospitalization: 38 days (18-49) vs. 14 days (11-21), p = 0.005. Plasma levels of Interleukin-6 were higher in patients with signs or symptoms in comparison with those without them: 43.5 pg/ml (19.7-49.4) vs. 8 pg/ml (3.6-20.7), p = 0.02. Red cell distribution width was also significantly higher: 15 (14.3-16.7) vs 13.2 (12.4-14.4), p = 0.001.ConclusionsWe found that over a third of the patients had ocular signs or symptoms. These had higher prevalence in patients with a more severe infection. No viral shedding was detected in the conjunctiva. Our results suggest that prompt detection of conjunctivitis signs/symptoms can serve as a helpful proxy to predict COVID-19 clinical phenotype.

Project description:Background:Few studies have been performed to investigate multiorgan failure occurring with extrapulmonary symptoms like diarrhea, anorexia, and vomiting. There has been no attempt at a systematic review on this major health issue. Hence, in this study, a meta-analysis was undertaken to quantify the overall risk of liver damage in COVID-19 patients and also find the overall variation in risk outcome. Materials and methods:A meta-analysis was carried out on the findings of four published studies that were related to the albumin, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels of COVID-19 patients. The pooled mean for each of these three measurements was estimated by using a random-effects model. Results:The pooled means for albumin, AST, and ALT in COVID-19 patients were 38.84 g/L [95% confidence interval (CI): 35.83-41.86], 27.28 IU/L (95% CI: 18.30-36.26), and 24.44 IU/L (95% CI: 15.73-33.15) respectively. There was a high degree of divergence among the studies, with the index of heterogeneity being more than 90%. Conclusion:The ALT and albumin pooled means were reported to be within the normal range; however, the pooled mean of the serum AST level was found to be high in COVID-19 patients. The pooled means reported in this study can be useful for working out the degree of liver damage in COVID-19 patients.
