A bibliometric analysis using machine learning to track paradigm shifts and analytical advances in forest ecology and forestry journal publications from 2010 to 2022

Forest habitats are critical for biodiversity,ecosystem services,human livelihoods,and well-being.Capacity to conduct theoretical and applied forest ecology research addressing direct(e.g.,deforestation)and indirect(e.g.,climate change)anthropogenic pressures has benefited considerably from new field-and statistical-techniques.We used machine learning and bibliometric structural topic modelling to identify 20 latent topics comprising four principal fields from a corpus of 16,952 forest ecology/forestry articles published in eight ecology and five forestry journals between 2010 and 2022.Articles published per year increased from 820 in 2010 to 2,354 in 2021,shifting toward more applied topics.Publications from China and some countries in North America and Europe dominated,with relatively fewer articles from some countries in West and Central Africa and West Asia,despite globally important forest resources.Most study sites were in some countries in North America,Central Asia,and South America,and Australia.Articles utilizing R statistical software predominated,increasing from 29.5%in 2010 to 71.4%in 2022.The most frequently used packages included lme4,vegan,nlme,MuMIn,ggplot2,car,MASS,mgcv,multcomp and raster.R was more often used in forest ecology than applied forestry articles.R software offers advantages in script and workflow-sharing compared to other statistical packages.Our findings demonstrate that the disciplines of forest ecology/forestry are expanding both in number and scope,aided by more sophisticated statistical tools,to tackle the challenges of redressing forest habitat loss and the socio-economic impacts of deforestation.

Knowledge,attitude and behaviour to evidence-based practice among psychiatric nurses:A cross-sectional survey

Objective To identify the status of knowledge,attitude,and behaviour toward evidence-based practice(EBP)among Chinese psychiatric nurses,and to examine the influencing factors of EBP behaviour.Methods We utilised a cross-sectional design.A total of 923 psychiatric nurses from 168 hospitals in 27 provinces in the mainland of China participated in our survey.The EBP questionnaire,the barriers to research utilisation scale and the facilitators to research utilisation scale were used for data collection via WeChat group from July 2018 to April 2019.Multiple regression analysis was used to analyse the influencing factors of psychiatric nurses’evidence-based practice behaviour.Results The score of Chinese psychiatric nurses’EBP attitude,behaviour and knowledge were 4.81±1.34,4.11±1.36 and 3.53±1.29,respectively.Multiple regression analysis showed that nurses’EBP behaviour was mainly determined by knowledge and attitude,which together explained 61.8%of the variance.The two top barriers were the dimensions of presentation and research.Facilitators include managerial support,employing nurses with research skills as models and providing advanced education on evidence-based nursing.Conclusion Psychiatric nurses have positive attitudes toward EBP,but their level of knowledge and behaviour is insufficient.Heavy workload,insufficient time,and a lack of knowledge and skills is the main barrier.Managerial support,employing nurses with research skills as models and providing advanced education are the main facilitators.

痴呆患者进食问题评估与管理指南的系统评价

目的对痴呆患者进食问题评估与管理相关指南进行质量评价和内容分析,为制订痴呆患者进食问题评估与管理规范提供依据。方法计算机检索国内外指南网、相关学会网站及数据库,搜集痴呆患者进食问题评估与管理相关指南,检索时限为建库至2018年12月19日。应用标准的质量评价工具对指南进行质量评价,汇总痴呆患者进食问题评估与管理的推荐意见。结果初检到450篇文献,最终纳入6篇指南、1篇专家共识、4篇最佳实践和2篇推荐实践。6篇指南均来自国外,使用临床指南研究与评估系统Ⅱ对其进行质量评价并计算各领域的平均得分,分别为范围和目的87.50%、参与人员61.58%、严谨性45.14%、清晰性78.70%、应用性35.07%和独立性33.33%,总体质量均为B级;纳入的专家共识、最佳实践、推荐实践分别来自中国、美国和澳大利亚。进食问题评估与管理有关推荐意见涉及营养和进食问题评估、调整进餐环境、维持进食自主性、调整食物类型和提供方式、照护者支持、吞咽困难应对、营养补充剂、肠内营养8个方面。结论纳入的指南质量中等,在应用性、独立性和严谨性领域有待提高。关于进食评估与管理的推荐意见散在分布,缺乏针对具体进食问题的应对措施,部分推荐意见尚有争议。

Retrospective analysis of diffuse interstitial lung disease in 10 hospitals in Tianjin

Objective:To investigate the constituent ratio and clinical features of diffuse interstitial lung disease(DILD)in Tianjin,and to identify the existing problems of its diagnosis and treatment.Methods:Data of all patients diagnosed as DILD in ten comprehensive hospitals in Tianjin from 2003 to 2009 was collected.The disease constituent ratio of DILD to all kinds of diseases in the respiration department or in the whole hospital,the clinical manifestation,lung function,the result of blood gas analysis,and biopsy were analyzed.Results:A total of 804 DILD patients were included in the study aged(69.28±12.09)years with a male/female ratio of 1.32.The disease constituent ratios of DILD were 4.52‰in respiratory department and 0.31‰in the whole hospital in 2003,which increased to 35.9‰and 1.51‰respectively in 2009.Reticular abnormality(43.1%),ground glass(25.6%)and honeycombing(11.4%)were the predominant imaging manifestations.26.7%patients’lung function were tested,and 10.3%had diffusion function tests.Most patients presented with hypoxemia,and the average oxygenation index was(281±98.3)mmHg.Only 4.0%of patients underwent bronchoalveolar lavage,and 3.5%had pathologic data.Conclusion:The disease constituent ratio of DILD increased progressively from 2003 to 2009.A definite diagnosis of DILD demands cooperation of physicians,radiologists and pathologists.Doctors should attach more importance on lung function test,bronchoalveolar lavage and biopsy.
