Objective:To examine the differences in effectiveness and side effects between pyrimethamine-based and non-pyrimethamine-based regimens for toxoplasma encephalitis since the availability of pyrimethamine in Indonesia is currently limited due to its withdrawal from the market.Methods:A systematic review and meta-synthesis study that was carried out by following a protocol guided by the Preffered Reporting Items for Systematic Review and Meta-analysis(PRISMA).Effectiveness measures included clinical improvement,mortality,and radiological improvement.We evaluated selected articles narratively because of the limitations of homogeneity.The risk of bias in RCTs was assessed using the Cochrane Risk of Bias tool for RCT(ROB 2.0)and cohort studies were assessed using the Risk of Bias In Non-Randomized Studies of Interventions(ROBINS-1)tool.Research quality was assessed using the GradePro software.Results:We included two retrospective cohort studies and one RCT.Narrative outcome assessment in these three studies did not show significant difference in effectiveness between pyrimethamine-based and non-pyrimethamine-based regimens for toxoplasma encephalitis treatment.However,drug side effects were consistently higher in the pyrimethamine-based regimen.Conclusions:This study has a high risk of bias.The quality of the research also has a low recommendation value.However,the results may be considered for application if a standard regimen is not available. 展开更多

Objectives define the boundaries of complex engineering system.It is a hard work to identify the specific objectives of a complex engineering system.The objectives system development needs a complicated process,from nix to prototype,and to final definition.The total process will cover the following course:from chaos to well-ordered;from qualitativeness to combination of quantitativeness and qualitativenss,then from qualitativeness to quantitativeness(a recurrent process),expert experience and theoretical science,rationality and sensibility,synthesis analysis and meta-synthesis,routinization and non-routinization.Such process is explicit in phase development yet overlapped;mutually confined yet mutually independent;permeated conflicts yet pregnant in harmony.This article explores the complexity of Sutong Bridge's objectives development and the process of meta-synthesis in the Sutong Bridge engineering. 展开更多

Difficulties students confronted when facing dying patients challenge the quality of nursing education. A better understanding of students' experiences would enhance teachers' ability in helping students. This study aims to describe available evidence about nursing students' experiences when caring for dying patients and their families.Methods: A review of qualitative studies published between 2005 and 2017 was undertaken using the following databases: MEDLINE, CINAHL, ProQuest Central, ScienceDirect, and CNKI. The keywords included were nursing students, experience, care, end-of-life, and dying. Qualitative Assessment and Review Instrument was used to assess the quality of the studies by two independent reviewers. The data from the studies were analyzed by meta-synthesis.Results: Eighteen English and two Chinese studies were selected in this review. Four themes were emerged:(1) Students with dying patients: students did not have enough ability in symptoms control, comfort supply, and therapeutic communication for dying patients.(2) Students with the patients' families: students advocated more caring for patients' families.(3) Students with the surroundings: professional medical staffs, especially the nursing preceptors, were key roles in constructing a supporting system for students.(4) Students with themselves: nursing students underwent various negative feelings and adopted both negative and positive strategies to cope with such feelings;students experienced professional and personal development during the caring for dying patients.Conclusions: Nursing students' abilities in terminal symptom control, comfort supply, and therapeutic communication should be improved by more theoretic learning and simulation practice. The nursing preceptors were key roles in constructing a supporting system for students and helping them to control the negative emotions when facing dying patients. 展开更多

The purpose of this review is to integrate the psychological experience of infected individuals during the pandemic.The spread of the pandemic has led to psychological and emotional impacts on patients.A qualitative synthesis is needed to identify,appraise,and integrate the available qualitative findings to provide an evidence for the development of interventions.A meta-aggregation approach was used to analyze studies published in English from January 2020 to August 2021.The JBI Qualitative Assessment and Review Instrument was used to assess the methodological quality of included studies.The ConQual system was used to establish the dependability and credibility in the synthesized findings.Six phenomenological studies and one narrative inquiry with an overall quality score of 70%-100% were included.The research findings from 87 participants in eligible studies were aggregated into three categories based on similarity of meaning.Two synthesized findings were generated and rated as moderate based on the ConQual score.The synthesized findings suggested that participants had psychological distress such as fear,anxiety,loneliness,and uncertainty,but they accepted the fact of being infected and tried to adjust themselves using some self-coping strategies,such as diverting attention from disease,seeking help from professional counselors,relying on religious beliefs,and participating in religious activities.They would like to learn more about infections and diseases and needed more informational support from health-care professionals.They were looking forward to recovery from the disease. 展开更多
