An explorative study on document type assignment of review articles in Web of Science,Scopus and journals’websites

Purpose:Accurately assigning the document type of review articles in citation index databases like Web of Science(WoS)and Scopus is important.This study aims to investigate the document type assignation of review articles in Web of Science,Scopus and Publisher’s websites on a large scale.Design/methodology/approach:27,616 papers from 160 journals from 10 review journal series indexed in SCI are analyzed.The document types of these papers labeled on journals’websites,and assigned by WoS and Scopus are retrieved and compared to determine the assigning accuracy and identify the possible reasons for wrongly assigning.For the document type labeled on the website,we further differentiate them into explicit review and implicit review based on whether the website directly indicates it is a review or not.Findings:Overall,WoS and Scopus performed similarly,with an average precision of about 99% and recall of about 80%.However,there were some differences between WoS and Scopus across different journal series and within the same journal series.The assigning accuracy of WoS and Scopus for implicit reviews dropped significantly,especially for Scopus.Research limitations:The document types we used as the gold standard were based on the journal websites’labeling which were not manually validated one by one.We only studied the labeling performance for review articles published during 2017-2018 in review journals.Whether this conclusion can be extended to review articles published in non-review journals and most current situation is not very clear.Practical implications:This study provides a reference for the accuracy of document type assigning of review articles in WoS and Scopus,and the identified pattern for assigning implicit reviews may be helpful to better labeling on websites,WoS and Scopus.Originality/value:This study investigated the assigning accuracy of document type of reviews and identified the some patterns of wrong assignments.

肺炎支原体感染与儿童哮喘的相关性（英文）

Mycoplasma pneumoniae is a frequent cause of acute respiratory infections in both children and adults.It can cause pharyngitis,otitis,tracheobronchitis,or community-acquired pneumonia,but may also remain totally asymptomatic.Mycoplasma pneumoniae is an organism that reportedly has a strong relationship to asthma.The role of atypical bacterial infection in the pathogenesis of asthma is a subject of continuing debate.There is an increasing body of literature concerning the association between Mycoplasma pneumoniae(M.pneumoniae)and asthma pathogenesis.Moreover,many studies investigating such a link have been uncontrolled and have provided conflicting evidence,in part due to the difficulty in accurately diagnosing infection with these atypical pathogens.Large,general population-based prospective studies are necessary to investigate the development of asthma induced by M.pneumoniae infection in humans.This manuscript will review the relationship between M.pneumoniae infection and childhood asthma.

Microendoscopic discectomy for treatment of lumbar disc herniation

A lumbar microendoscopic discectomy(MED)is a minimally invasive surgical technique performed through a tubular device which is designed for the pain relieve caused by herniated discs pressing the nerve roots.In 1997,a new minimally invasive surgical approach for the management of symptomatic lumbar disc herniation,MED was introduced.This technique uses a tubular retractor system and a microendoscope for visualization rather than the operating microscope.However,recent literature suggests that MED is an effective microendoscopic system which has a fine long-term outcome in treating lumbar disc herniation.This article describes the operative techniques and outcomes reported in the literature for MED.

Role of intravenous immunoglobulin in suspected or proven neonatal sepsis

Neonatal sepsis remains the major cause of mortality and morbidity including neurodevelopmental impairment and prolonged hospital stay in newborn infants. Despite of advances in technology and optimal antibiotic treatment,incidence of neonatal sepsis and its complications remains unacceptably high especially in developing countries. Premature neonates in particular are at higher risk due to developmentally immature host defence mechanisms. Though not approved by Food and Drug Administration(FDA) U. S. A,off label use of intravenous immunoglobulin as prophylactic or adjuvant agent in suspected or proven neonatal infections continues in many countries. In a recent large multicenter clinical trial by International Neonatal Immunotherapy Study(INIS) group, the use of polyvalent IgG immune globulin was not associated with significant differences in the risk of major complications or other adverse outcomes in neonates with suspected or proven sepsis. Hence,use of intravenous immunoglobulin in suspected or proven neonatal sepsis is not recommended. The expense of prophylactic use of intravenous immunoglobulin administration for both term and preterm newborn population,given the minimal benefit as demonstrated by many individual studies and by meta-analysis is not justified.
