Exponential growth in the number of those affected makes this virus such a threat. The current meta-analysis aimed to estimate the prevalence of underlying disorders in hospitalized COVID-19 patients. Methods A comprehensive systematic search was performed on PubMed, Scopus, Web of science, and Google scholar, to find articles published until 15 February 2020. All relevant articles that reported clinical characteristics and epidemiological information of hospitalized COVID-19 patients were included in the analysis. Results The data of 76993 patients presented in 10 articles were included in this study. According to the meta-analysis, the pooled prevalence of hypertension, cardiovascular disease, smoking history and diabetes in people infected with SARS-CoV-2 were estimated as 16.37% (95%CI 10.15%-23.65%), 12.11% (95%CI 4.40%-22.75%), 7.63% (95%CI 3.83%-12.43%) and 7.87% (95%CI 6.57%-9.28%), respectively. Conclusion According to the findings of the present study, hypertension, cardiovascular diseases, diabetes mellitus, smoking, chronic obstructive pulmonary disease (COPD), malignancy, and chronic kidney disease were among the most prevalent underlying diseases among hospitalized COVID-19 patients, respectively.Introduction The outbreak of the new Coronavirus in China in December 2019 and subsequently in various countries around the world has raised concerns about the possibility of vertical transmission of the virus from mother to fetus. The present study aimed to review published literature in this regard. Methods In this narrative review, were searched for all articles published in various databases including PubMed, Scopus, Embase, Science Direct, and Web of Science using MeSH-compliant keywords including COVID-19, Pregnancy, Vertical transmission, Coronavirus 2019, SARS-CoV-2 and 2019-nCoV from December 2019 to March 18, 2020 and reviewed them. All type of articles published about COVID-19 and vertical transmission in pregnancy were included. Results A review of 13 final articles published in this area revealed that COVID-19 can cause fetal distress, miscarriage, respiratory distress and preterm delivery in pregnant women but does not infect newborns. There has been no report of vertical transmission in pregnancy, and it has been found that clinical symptoms of COVID-19 in pregnant women are not different from those of non-pregnant women. Conclusion Overall, due to lack of appropriate data about the effect of COVID-19 on pregnancy, it is necessary to monitor suspected pregnant women before and after delivery. For confirmed cases both the mother and the newborn child should be followed up comprehensively.SARS-CoV-2 is a newly emerging human infectious coronavirus that causes COVID-19, which has been recognized as a pandemic by the World Health Organization (WHO) on March 11th. There is still no vaccine or definitive treatment for this virus because its pathogenesis and proliferation pathways are still unknown. Therefore, in this article, new potential COVID-19 therapies are briefly reviewed.According to the TURHEP study, the prevalence of Helicobacter pylori in Turkey is 82.5%. After FDA approval in 1995, many countries have used standard triple therapy (proton pump inhibitor 40 mg b.i.d clarithromycin 500 mg b.i.d and amoxicillin 1 gr b.i.d) for Helicobacter pylori treatment. In the beginning, eradication rates were above 90% in many countries; however, current studies have demonstrated a prominent decrease in successful treatment rates, even down to 60%. This unfavorable reduction stimulated searches for new treatment protocols. Treatment protocols differ according to country, prevalence, cost-effectiveness, antibiotic resistance, CYP2C19 polymorphism and eradication rates. Thus, each country/region needs to revise its own therapeutic results and the efficacy of various eradication regimens in the treatment of Helicobacter pylori. This report aims to review the current status of Helicobacter pylori treatment in Turkey and to provide recommendations for rational therapeutic considerations for the eradication of the bacterium.

Long non-coding RNAs (lncRNA) are in the RNA group that has longer than 200 nucleotides, and non-protein coding transcripts. In recent years, the potential has attracted considerable attention as new important biological regulators. MSC2530818 clinical trial LncRNAs play a critical role in regulating the activity and localization of proteins, processing the production of small RNAs, and processing other RNAs. They are also involved in cell differentiation, cell cycle, proliferation, apoptosis, migration and invasion by modulation of gene expression. Abnormal expression of LncRNAs has an important role in the function of oncogenes and tumor suppressor genes. Recently, there has been an increasing number of studies on the tumorigenic effects of specific lncRNAs in the initiation and progression of cancer. In this review, general information about lncRNAs is provided, including the biological importance of lncRNAs in cancer diseases and their potential development in therapeutic applications.

Musculoskeletal signs and symptoms are not uncommon and manifested as arthritis and myalgia. Myalgia may be spontaneous or exercise-induced that mostly affects lower limbs and spontaneously resolves in 2-3 days. Protracted febrile myalgia syndrome (PFMS) is another form of rare and severe muscle involvement in FMF. PFMS affects all muscle groups and lasts for several weeks. Herein we present a pediatric case of PFMS that presented as the first manifestation of FMF, not responded to prednisolone at all but showed dramatic improvement with anakinra. Our case has a few distinctive points. She did not have a diagnosis of FMF and also she did not have any previous complaints compatible with FMF. Thus, PFMS was the first sign of FMF in this patient. Most of the cases of PFMS show dramatic response to corticosteroids, but our case did not respond at all to high-dose corticosteroids and anakinra resulted in rapid resolution of the symptoms.
