Introduction. Withania somnifera (WS) also known as ashwagandha is a well-known medicinal plant used in traditional medicine in many countries for infertility treatment. The present study was aimed at systemically reviewing therapeutic effects of WS on the reproductive system. Methods. This systematic review study was designed in 2016. Required data were obtained from PubMed, Scopus, Google Scholar, Cochrane Library, Science Direct, Web of Knowledge, Web of Science, and manual search of articles, grey literature, reference checking, and expert contact. Results. WS was found to improve reproductive system function by many ways. WS extract decreased infertility among male subjects, due to the enhancement in semen quality which is proposed due to the enhanced enzymatic activity in seminal plasma and decreasing oxidative stress. Also, WS extract improved luteinizing hormone and follicular stimulating hormone balance leading to folliculogenesis and increased gonadal weight, although some animal studies had concluded that WS had reversible spermicidal and infertilizing effects in male subjects. Conclusion. WS was found to enhance spermatogenesis and sperm related indices in male and sexual behaviors in female. But, according to some available evidences for spermicidal features, further studies should focus on the extract preparation method and also dosage used in their study protocols.

Background: The aim of this systematic review of systematic reviews was to identify, summarise, and synthesise the available evidence of systematic reviews (SRs) and meta-analyses (MAs) on the preventative and therapeutic psychological and physical effects of forest-based interventions. Methods: Both bibliographic databases and grey literature sources were searched for SRs and MAs published until May 2020. Eight databases were searched for relevant articles: MEDLINE, Embase, Web of Science, Cochrane Library, PsycInfo, CiNii, EBSCO, and Scopus. Grey literature was sourced from Google Scholar and other web-based search tools. SRs and MAs that included randomised controlled (RCT), non-randomised controlled (NRCT), and non-controlled trials (NCT) on health-related effects of forest-based interventions were eligible if they had searched at least two databases. The methodological quality of eligible reviews was assessed by AMSTAR-2. Results: We evaluated 11 systematic reviews covering 131 different primary intervention studies, mostly from Asian countries, three of which included supplementary meta-analyses. The quality assessment resulted in moderate confidence in the results of two reviews, low confidence in six, and critically low confidence in three. The results of the eight moderate and low-rated reviews indicated that forest-based interventions are beneficial to the cardiovascular system, immune system, and mental health (in the areas of stress, depression, anxiety, and negative emotions). Evidence for the effectiveness of forest-based interventions on metabolic parameters in adults, the severity of atopic dermatitis in children and adolescents, and social skills and sociality in healthy primary school children was weak. Discussion/Conclusions: Evidence suggests beneficial therapeutic effects of forest-based interventions on hypertension, stress, and mental-health disorders, such as depression and anxiety. Changes in immunological and inflammatory parameters after forest therapy should be verified in bio-geographically native forests. In the future, more attention should be paid to careful planning, implementation, and reporting of primary studies and to systematic reviews on the effects of forest-based interventions.

Abstract Background Gender-affirming hormone (GAH) therapy aims to support the transition of transgender people to their gender identity. GAHs can induce changes in their secondary sex characteristics such as the development of breasts in transgender females and increased muscle mass in transgender males. The face and its surrounding tissues also have an important role in gender confirmation. The aim of this scoping review is to systematically map the available evidence in order to provide an overview of the effects of GAH therapy on the hard and soft tissues of the craniofacial complex in transgender people. Methods/design The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA) extension for Scoping Reviews was consulted for reporting this protocol. The methods were based on the Arksey and O’Malley’s framework and the Reviewer’s Manual of the Joanna Briggs Institute for conducting scoping reviews. Ten transgender people were involved in the development of the primary research question through short interviews. The eligibility criteria were defined for transgender people undergoing GAH therapy and for quantitative and qualitative outcomes on the hard and soft tissues of the craniofacial complex. Eligible sources of evidence include observational, experimental, qualitative, and mixed method studies. No exclusion criteria will be applied for the language of publication and the setting. To identify eligible sources of evidence, we will conduct searches from inception onwards in PubMed, Embase.com, the Cochrane Library, Web of Science Core Collection, Scopus, CINAHL, LIVIVO, and various grey literature sources such as Google Scholar. Two reviewers will independently select eligible studies in these information sources and will subsequently conduct data extraction. The same operators will chart, categorize, and summarize the extracted data. A narrative summary of findings will be conducted. Frequency counts of quantitative and qualitative data on items such as concepts, populations, interventions, and other characteristics of the eligible sources will be given. Where possible, these items will be mapped descriptively. Discussion We chose the scoping review over the systematic review approach, because the research questions are broad-spectrum and the literature is expected to be widely scattered. No systematic review has previously assessed this topic. Identifying knowledge gaps in this area and summarizing and disseminating research findings are important for a wide spectrum of stakeholders, in particular, for transgender people who want to undergo additional interventions such as plastic or orthognathic surgery or orthodontics.

Asthma is the most common pediatric disease, characterized by chronic airway inflammation and airway hyperresponsiveness. There are several management options for asthma, but no specific treatment. Extracellular vesicles (EVs) are powerful cellular mediators of endocrine, autocrine and paracrine signalling, and can modulate biophysiological function in vitro and in vivo. A thorough investigation of therapeutic effects of EVs in asthma has not been conducted. Therefore, this systematic review is designed to synthesize recent literature on the therapeutic effects of EVs on physiological and biological outcomes of asthma in pre-clinical studies. An electronic search of Web of Science, EMBASE, MEDLINE, and Scopus will be conducted on manuscripts published in the last five years that adhere to standardized guidelines for EV research. Grey literature will also be included. Two reviewers will independently screen the selected studies for title and abstract, and full text based on the eligibility criteria. Data will be extracted, narratively synthesized and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. This systematic review will summarize the current knowledge from preclinical studies investigating the therapeutic effects of EVs on asthma. The results will delineate whether EVs can mitigate biological hallmarks of asthma, and if so, describe the underlying mechanisms involved in the process. This insight is crucial for identifying key pathways that can be targeted to alleviate the burden of asthma. The data will also reveal the origin, dosage and biophysical characteristics of beneficial EVs. Overall, our results will provide a scaffold for future intervention and translational studies on asthma treatment.

Background: As people age, they become increasingly vulnerable to the untoward effects of medicines due to changes in body systems. These may result in medicines related problems (MRPs) and consequent decline or deterioration in health. Aim: To identify MRPs, indicators of deterioration associated with these MRPs, and preventative interventions from the literature. Design and Setting: Systematic review of primary studies on MRPs originating in Primary Care in older people. Methods: Relevant studies published between 2001 and April 2018 were obtained from Medline (via PubMed), CINAHL, Embase, Psych Info, PASCAL, Scopus, Cochrane Library, Science Direct, and Zetoc. Falls, delirium, pressure ulcer, hospitalization, use of health services and death were agreed indicators of deterioration. The methodological quality of included studies was assessed using the Down and Black tool. Results: There were 1858 articles retrieved from the data bases. Out of these, 21 full text articles met inclusion criteria for the review. MRPs identified were medication error, potentially inappropriate medicines, adverse drug reaction and non-adherence. These were associated with indicators of deterioration. Interventions that involved doctors, pharmacists and patients in planning and implementation yielded benefits in halting MRPs. Conclusion: This Systematic review summarizes MRPs and associated indicators of deterioration. Appropriate interventions appeared to be effective against certain MRPs and their consequences. Further studies to explore deterioration presented in this systematic review is imperative.

Abstract Visceral leishmaniasis (VL) is endemic in 70 countries and has been reported in 12 countries of Latin America, with over 90% of the cases reported in Brazil, where epidemics have occurred since 1980. The objective of this review is to describe the factors associated with the occurrence of VL epidemics in humans in urban areas. A systematic review was conducted according to the PRISMA-P guidelines. The databases PubMed (by Medline), Cochrane Library, Embase, Amed, LILACS and grey literature [Google Scholar and handsearch of the database of the Information System for Notifiable Diseases (SINAN) of Brazil's Unified Health System] were used. The protocol was registered under PROSPERO (CRD42019128998). Climatic, environmental factors and indicators of urban social structure were described as influencing the outbreaks in the North and Northeast regions. Gender and age characteristics were related to a greater chance of developing VL in the Central-West, Northeast and Southeast regions. Vector indicators showed a positive correlation with the incidence of VL in studies in the Northeast region. In the Southeast and Northeast regions, studies revealed the presence of dogs with positive correlation with VL. Knowledge gaps remain regarding the contribution to the increase in the risk factors described in ecological approaches, as no analysis was performed at the individual level, and it is still necessary to discuss the influence of other associated elements in epidemic episodes in the spread of VL.

Abstract Background Sedentary behaviour is when someone is awake, in a sitting, lying or reclining posture and is an independent risk factor for multiple causes of morbidity and mortality. A dose-response relationship has been demonstrated, whereby increasing sedentary time corresponds with increasing mortality rate. This study aimed to identify current levels of sedentary behaviour among General Practitioners (GPs), by examining and synthesising how sedentary behaviour has been measured in the primary care literature. Methods A systematic review was conducted to identify studies relating to levels of sedentary behaviour among GPs. Searches were performed using Medline®, Embase®, PscycINFO, Web of Science and the Cochrane Library, from inception of databases until January 2020, with a subsequent search of grey literature. Articles were assessed for quality and bias, with extraction of relevant data. Results The search criteria returned 1707 studies. Thirty four full texts were reviewed and 2 studies included in the final review. Both were cross-sectional surveys using self-reported estimation of sedentary time within the International Physical Activity Questionnaire (IPAQ). Keohane et al. examined GP trainees and GP trainers in Ireland. 60% reported spending in excess of 7 h sitting each day, 24% between 4 and 7 h, and 16% less than or equal to 4 h. Suija et al. examined female GPs in Estonia. The mean reported daily sitting time was 6 h and 36 min, with 56% sitting for over 6 h per day. Both studies were of satisfactory methodological quality but had a high risk of bias. Conclusion There is a paucity of research examining current levels of sedentary behaviour among GPs. Objective data is needed to determine GPs’ current levels of sedentary behaviour, particularly in light of the increase in remote consulting as a result of the COVID-19 pandemic.

IntroductionCardiovascular diseases (CVDs) are among the leading causes of death globally. Electronic health records (EHRs) provide a rich data source for research on CVD risk factors, treatments and outcomes. Researchers must be confident in the validity of diagnoses in EHRs, particularly when diagnosis definitions and use of EHRs change over time. Our systematic review provides an up-to-date appraisal of the validity of stroke, acute coronary syndrome (ACS) and heart failure (HF) diagnoses in European primary and secondary care EHRs.Methods and analysisWe will systematically review the published and grey literature to identify studies validating diagnoses of stroke, ACS and HF in European EHRs. MEDLINE, EMBASE, SCOPUS, Web of Science, Cochrane Library, OpenGrey and EThOS will be searched from the dates of inception to April 2019. A prespecified search strategy of subject headings and free-text terms in the title and abstract will be used. Two reviewers will independently screen titles and abstracts to identify eligible studies, followed by full-text review. We require studies to compare clinical codes with a suitable reference standard. Additionally, at least one validation measure (sensitivity, specificity, positive predictive value or negative predictive value) or raw data, for the calculation of a validation measure, is necessary. We will then extract data from the eligible studies using standardised tables and assess risk of bias in individual studies using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Data will be synthesised into a narrative format and heterogeneity assessed. Meta-analysis will be considered when a sufficient number of homogeneous studies are available. The overall quality of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation tool.Ethics and disseminationThis is a systematic review, so it does not require ethical approval. Our results will be submitted for peer-review publication.PROSPERO registration numberCRD42019123898

Context: Coronavirus disease 2019 (COVID-19) is one of the most dangerous viral diseases that started spreading in China in 2019 and has caused many deaths so far. Therefore, this study aimed to systematically review studies on the prevention, diagnosis, and treatment of coronavirus in infants and children. Evidence Acquisition: This is a systematic review study conducted in PubMed/Medline, Scopus, Embase, Cochrane Library, Science Direct, and Web of Science (ISI) databases on October 8 2020. Also, we searched Google Scholar to find all in-press articles. To extract data, a checklist was used, which included the author’s name, year of publication, purpose, age group of patients under study, and the protocol applied for coronavirus prevention, diagnosis, and treatment. The search was done with AND, OR, NOT strategies. The results of the study were reported in a descriptive manner using Endnote version 8 software. Results: According to the results of the basic search, 120 articles were extracted on the management of coronavirus. Of the articles extracted, 30 were articles related to children, of which only eight developed protocols for prevention, diagnosis, and treatment in infants and children. Of the studies extracted, six were from China, one from Iran, and one from Australia. It should be noted that the protocols for infants were extracted from two studies on infants and four studies on the pediatric group. Conclusions: It is proposed to consider and study this systematic review of coronavirus management in infants and children.

Background A number of primary studies in Ethiopia address the prevalence of birth asphyxia and the factors associated with it. However, variations were seen among those studies. The main aim of this systematic review and meta-analysis was carried out to estimate the pooled prevalence and explore the factors that contribute to birth asphyxia in Ethiopia. Methods Different search engines were used to search online databases. The databases include PubMed, HINARI, Cochrane Library and Google Scholar. Relevant grey literature was obtained through online searches. The funnel plot and Egger’s regression test were used to see publication bias, and the I-squared was applied to check the heterogeneity of the studies. Cross-sectional, case-control and cohort studies that were conducted in Ethiopia were also be included. The Joanna Briggs Institute checklist was used to assess the quality of the studies and was included in this systematic review. Data entry and statistical analysis were carried out using RevMan 5.4 software and Stata 14. Result After reviewing 1,125 studies, 26 studies fulfilling the inclusion criteria were included in the meta-analysis. The pooled prevalence of birth asphyxia in Ethiopia was 19.3%. In the Ethiopian context, the following risk factors were identified: Antepartum hemorrhage(OR: 4.7; 95% CI: 3.5, 6.1), premature rupture of membrane(OR: 4.0; 95% CI: 12.4, 6.6), primiparas(OR: 2.8; 95% CI: 1.9, 4.1), prolonged labor(OR: 4.2; 95% CI: 2.8, 6.6), maternal anaemia(OR: 5.1; 95% CI: 2.59, 9.94), low birth weight(OR = 5.6; 95%CI: 4.7,6.7), meconium stained amniotic fluid(OR: 5.6; 95% CI: 4.1, 7.5), abnormal presentation(OR = 5.7; 95% CI: 3.8, 8.3), preterm birth(OR = 4.1; 95% CI: 2.9, 5.8), residing in a rural area (OR: 2.7; 95% CI: 2.0, 3.5), caesarean delivery(OR = 4.4; 95% CI:3.1, 6.2), operative vaginal delivery(OR: 4.9; 95% CI: 3.5, 6.7), preeclampsia(OR = 3.9; 95% CI: 2.1, 7.4), tight nuchal cord OR: 3.43; 95% CI: 2.1, 5.6), chronic hypertension(OR = 2.5; 95% CI: 1.7, 3.8), and unable to write and read (OR = 4.2;95%CI: 1.7, 10.6). Conclusion According to the findings of this study, birth asphyxia is an unresolved public health problem in the Ethiopia. Therefore, the concerned body needs to pay attention to the above risk factors in order to decrease the country’s birth asphyxia.

Abstract Background: Congenital CMV infection is the first worldwide cause of congenital viral infection and a major cause of sensorineural hearing loss and mental retardation. As systematic screening of pregnant women and newborns is still debated in many countries, this systematic review aims to provide the state of the art on current practices concerning management of congenital CMV infection.Methods: We will perform electronically searches on MEDLINE, EMBASE, Cochrane Library (CENTRAL), ClinicalTrials.gov, Web of Science and hand searches in grey literature. Interventions regarding biological, imaging, and therapeutic management of infected pregnant women, fetuses and neonates/children (from birth to 6 years old) will be studied in this systematic review. Study screening will be performed in duplicate by two independent reviewers and risk of bias will be evaluated with the ROBINS-I tool. Discussion: This review will provide the state of the art of current management of congenital CMV infection in pregnant women, fetuses, neonates and children until 6 years old, in order to have an overview of current practices of congenital CMV infection.Systematic review registration: PROSPERO CRD42019124342
