There is debate over the effectiveness of using touch-screen tablet technology on overall student learning gains. This article provides a meta-analysis of studies that used tablets for the delivery of math interventions, programs, or apps to increase student math achievement. A total of 20 group design studies with 2,805 participants were included in the meta-analysis. Overall, tablet-based math interventions provided moderate positive effects for student math gains. Significant moderator variables included participant ethnicity, and socio-economic status, selecting a specific app for use, minutes in intervention, dependent variable, and type of control group. Discussion focuses on the need for more rigorous methodology and reporting of participant and design variables in future studies and the implications for researchers and practitioners when using tablets as a delivery method for math interventions.

Educational priority policy schools differ in the learning outcomes they achieve with second language learners. School effectiveness research suggests that teachers can make a difference, but fails to make clear exactly how they can do so. This quasi-experimental study combines a comparison group design with a control group design to answer the research question "How effective are five primary school teachers in creating powerful learning environments for knowledge construction and academic language learning?" This article focuses on which types of students benefit the most from a classroom intervention, called The case DNA. The case DNA is a task-based lesson unit containing eight clear lesson objectives and the necessary lesson materials and learning activities to realize these lesson objectives. The teachers were free to adapt the lesson unit to their own teaching styles. The results of the students on the pre-test, post-test and delayed post-test DNA were analysed using multilevel analysis. Results show that socio-economic status, language proficiency, number of turns, teacher expectations and home language Turkish predict differential learning outcomes.

ObjectiveWe aimed to examine whether eHealth interventions can effectively improve anthropometric and biochemical indicators of patients with metabolic syndrome (MetS).DesignSystematic review and meta-analysis.MethodsPubMed, the Web of Science, Embase, Medline, CINAHL, PsycINFO, the Cochrane Library, the Chinese National Knowledge Infrastructure, the Wanfang and Weipu databases were comprehensively searched for papers that were published from database inception to May 2019. Articles were included if the participants were metabolic syndrome (MetS) patients, the participants received eHealth interventions, the participants in the control group received usual care or were wait listed, the outcomes included anthropometric and biochemical indicators of MetS, and the study was a randomised controlled trial (RCT) or a controlled clinical trial (CCT). The Quality Assessment Tool for Quantitative Studies was used to assess the methodological quality of the included articles. The meta-analysis was conducted using Review Manager V.5.3 software.ResultsIn our review, seven RCTs and two CCTs comprising 935 MetS participants met the inclusion criteria. The results of the meta-analysis revealed that eHealth interventions resulted in significant improvements in body mass index (standardised mean difference (SMD)=−0.36, 95% CI (−0.61 to −0.10), p<0.01), waist circumference (SMD=−0.47, 95% CI (−0.84 to −0.09), p=0.01) and systolic blood pressure(SMD=−0.35, 95% CI (−0.66 to −0.04), p=0.03) compared with the respective outcomes associated with the usual care or wait-listed groups. Based on the included studies, we found significant effects of the eHealth interventions on body weight. However, we did not find significant positive effects of the eHealth interventions on other metabolic parameters.ConclusionsThe results indicated that eHealth interventions were beneficial for improving specific anthropometric outcomes, but did not affect biochemical indicators of MetS. Therefore, whether researchers adopt eHealth interventions should be based on the purpose of the study. More rigorous studies are needed to confirm these findings.

During the practicum, pre-service teachers (PSTs) practice instructional skills such as lesson planning and clarity of instruction. Different approaches to assisting PSTs with coaching, mentoring, or supervision have been developed to improve PSTs’ instructional skills during the practicum. We conducted a meta-analysis based on quasi-experimental and experimental control group design studies. The results showed a small and significant overall effect on instructional skills (d = .41). Cooperating teachers’ or supervisors’ cognitive modeling (i.e., making cognitive processes explicit in demonstrating teaching-related practices) of lesson planning and teaching practices based on the cognitive apprenticeship framework was a significant moderator (d = .89).

Abstract Objectives To examine the effectiveness and safety of yoga for women with sleep problems by performing a systematic review and meta-analysis.Methods Medline/PubMed, Clincalkey, ScienceDirect, Embase, PsycINFO, and the Cochrane Library were searched throughout the month of June 2019. Randomized controlled trials comparing yoga groups with control groups in women with sleep problems were included. Two reviewers independently evaluated risk of bias by using the risk of bias tool suggested by the Cochrane Collaboration for programming and conducting systematic reviews and meta-analyses. The main outcome measure was sleep quality or the severity of insomnia, which was measured using subjective instruments, such as the Pittsburgh Sleep Quality Index (PSQI), Insomnia severity index (ISI), or objective instruments, such as polysomnography, actigraphy, and safety of the intervention. For each outcome, standardized mean difference (SMD) and 95% confidence intervals (CIs) were determined. Results Nineteen studies including 1832 participants were included in this systematic review. Meta-analyses revealed positive effects of yoga using PSQI or ISI scores in 16 randomized control trials (RCTs) compared with the control group in improving sleep quality in women, PSQI (SMD = −0.54; 95% CI = −0.89 to −0.19 ; P = 0.003). However, three RCTs revealed no effects of yoga compared with the control group in reducing the severity of insomnia in women using ISI (SMD = −0.13; 95% CI = −0.74 to 0.48; P = 0.69). Seven RCTs revealed no evidence for effects of yoga compared with the control group in improving sleep quality for women with breast cancer using PSQI (SMD = −0.15 ; 95% CI = −0.31 to 0.01; P = 0.5). Four RCTs revealed no evidence for the effects of yoga compared with the control group in improving the sleep quality for peri-or postmenopausal women using PSQI (SMD = −0.31; 95% CI = −0.95 to 0.33; P = 0.34).Yoga was not associated with serious adverse events. Discussion This systematic review and meta-analysis found that yoga intervention in some groups of women was beneficial in managing sleep problems. Despite certain disadvantages in methodology in the included studies, yoga may be recommended as a complementary therapy to women.

Abstract Background: Hospital clinical pharmacists have been working in many countries for many years and clinical pharmaceutical care have a positive effect on the recovery of patients. In order to evaluate the clinical effectiveness and economic outcomes of clinical pharmaceutical care, relevant clinical trial studies were reviewed and analysed. Methods: Two researchers searched literatures published from January 1992 to October 2019, and screened them by keywords like pharmaceutical care, pharmaceutical services, pharmacist interventions, outcomes, effects, impact, etc. Then, duplicate literatures were removed and the titles, abstracts and texts were read to screen literatures according to inclusion and exclusion criteria. Key data in the literature were extracted, and Meta-analysis was conducted using the literature with common outcome indicators. Results: A total of 3299 articles were retrieved, and 42 studies were finally included. Twelve of them were used for meta-analysis. Among the 42 studies included, the main results of pharmaceutical care showed positive effects, 36 experimental groups were significantly better than the control group, and the remaining 6 studies showed mixed or no effects. Meta-analysis showed that clinical pharmacists had significant effects on reducing systolic blood pressure and diastolic blood pressure and shortening hospitalization days (P<0.05), but no statistical significance in reducing medical costs (P>0.05). Conclusion: clinical pharmacists' pharmaceutical care has a significant positive effect on patients' clinical effects, but has no significant economic effect.

Positive Effects

The positive effects of physical training on heart rate variability (HRV) in healthy adults are widely recognized; however, the responsiveness to training in healthy children has not yet been established. The aim of this study was to determine the influence of physical training on HRV in prepubertal healthy children. Systematic computerized searches were performed from 1950 to 2012 in the following databases: Medline, Embase, Cinahl, Lilacs, Scielo, SportDiscus, ProQuest; Web of Science; PEDro; Academic Search Premier and the Cochrane Library. The key words used were: heart rate variability, autonomic nervous system, exercise training, physical activity, continuous exercise, intermittent exercise, children, prepubescent, adolescents, and healthy. Although the database search initially identified 6,164 studies, after removing duplicates and excluding by title the number was 148, however, only 2 studies were included in this systematic review. The meta-analysis compared the experimental group (n = 29) with the control group (n = 28) for the HRV parameters: RR intervals, SDNN, RMSSD, pNN50, LF (log), HF (log), LF/HF and Total Power (log). The meta-analysis demonstrated similar HRV indices between both the experimental and control groups. In conclusion, the available results from randomized controlled trials do not support the hypothesis that physical training improves HRV in healthy children[AUQ2].

Purpose: To evaluate the safety and efficacy of remdesivir in adult patients with COVID-19. Methods: PubMed, Embase, Scopus, Web of Science, Cochrane Library, ClinicalTrials.gov, and medRxiv databases were searched using a search strategy tailored to each database. The Consolidated Standards of Reporting Trials (CONSORT) and Strengthening the reporting of observational studies in epidemiology (STROBE) checklists were used for the studies' qualitative assessment. The outcomes studied were mortality, all adverse events, serious adverse events, and clinical improvement. The quantitative synthesis was conducted using fixed and random effects models in the CMA 2.2. Heterogeneity was tested using the I-squared (I2) measure. Results: In general, six studies, including five randomized controlled trials and one cohort study were found eligible. Comparison of the findings related to both groups receiving remdesivir (10-day remdesivir group) and placebo/control group showed that remdesivir treatment had no significant effect on mortality at day 14 of the treatment (RR=0.769; 95% CI :0.563-1.050; p=0.098), and all adverse events (RR= 1.078; 95% CI: 0.908-1.279; p= 0.392). However, remdesivir had a significant effect on clinical improvement at day 14 compared to placebo/control (OR= 1.447; 95% CI: 1.005-2.085; p= 0.047) and reduced serious adverse events (RR= 0.736; 95% CI: 0.611-0.887; p= 0.001). Conclusion: Remdesivir has positive effects on clinical improvement, and reduction of the risk of serious adverse events. However, it does not influence the mortality at day 14 of treatment.
