In 2008, Browder and colleagues published a meta-analysis on mathematics instruction for learners with significant cognitive disabilities and found that most skills taught to these students were only from two of the five strands recommended by the National Council for Teachers of Mathematics (i.e., Number and Operations, and Measurement). A review of the literature since Browder et al. yielded an additional 29 studies. When results from both reviews were compared, a greater percentage of studies taught skills from three strands (i.e., Number and Operations, Geometry, and Algebra), whereas the percentage teaching skills from the Measurement strand decreased and the percentage teaching skills from the Data Analysis and Probability strand was unchanged. In addition, a systematic evaluation of the studies’ instructional components found evidence to support the use of systematic instruction, in vivo instruction, system of least prompts strategy, constant time delay strategy, and task-analytic instruction as evidence-based practices for teaching mathematics to learners with significant cognitive disabilities. Implications for practice include the use of systematic instruction and in vivo procedures, the need for practitioners to have a deep understanding of mathematics, and the importance of relevancy when teaching a variety of mathematics skills.

Abstract Objective The European Society of Cardiology (ESC) 0/3-hour algorithm is one of the most widely strategies used for rule-out or rule-in of acute myocardial infarction (AMI). However, a systematic evaluation of its performance has not been conducted. Furthermore, recent studies showed that the 0/3-hour algorithm is non-superior to the 0/1-hour algorithm. Purpose This study aims to summarize the safety and efficacy of the 0/3-hour algorithm and its comparative performance with the 0/1-hour algorithm. Methods We conducted literature search on PubMed, Embase, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials for studies published between 1 January 2008 and 31 May 2019. A bivariate random-effects meta-analysis was used to estimate the primary and secondary outcomes, defined as index myocardial infarction and triage efficacy, major adverse cardiac event (MACE) or mortality at 30 days, respectively. Results A total of 10,832 patients from 9 studies with a pooled AMI prevalence of 16% were analyzed. The 0/3-hour algorithm ruled out 69% of the patients with a pooled sensitivity of 94.2% [95% CI: 87.6%–97.4%] and negative predictive value of 98.6% [95% CI: 97.0%–99.4%]; 17% of the patients were ruled in with a pooled specificity of 94.9% [95% CI: 88.6%–97.8%] and positive predictive value of 72.9% [95% CI: 54.6%–85.7%]. The 30-day mortality and 30-day MACE for patients that were ruled out were 0.0% [95% CI: 0.0%–0.0%] and 1.4% [95% CI: 0.9%–2.0%], respectively. In a pooled analysis of 3 cohorts, the 0/3-hour algorithm had a non-superior sensitivity compared with the 0/1-hour algorithm (94.4% [95% CI: 87.0%–97.7%] vs. 98.4% [95% CI: 95.4%–99.7%]). The 0/3-hour algorithm also had a similar rule-out efficacy compared with the 0/1-hour algorithm (52% [95% CI: 39%–65%] vs. 53% [95% CI: 42%–64%]). Conclusion The widely used 0/3-hour algorithm has sensitivity substantially below the consensus goal of 99% and may not be sufficiently safe for triage of myocardial infarction. Furthermore, the 0/3-hour algorithm is not superior to the 0/1-hour algorithm despite the additional triage time.

AbstractAnimal models provide an opportunity to assess the optimal treatment way and the underlying mechanisms of direct clinical application of adipose-derived stem cells (ADSCs). Previous studies have evaluated the effects of primitive and induced ADSCs in animal models of Parkinson’s disease (PD). Here, eight databases were systematically searched for studies on the effects and in vivo changes caused by ADSC intervention. Quality assessment was conducted using a 10-item risk of bias tool. For the subsequent meta-analysis, study characteristics were extracted and effect sizes were computed. Ten out of 2324 published articles (n = 169 animals) were selected for further meta-analysis. After ADSC therapy, the rotation behavior (10 experiments, n = 156 animals) and rotarod performance (3 experiments, n = 54 animals) were improved (P < 0.000 01 and P = 0.000 3, respectively). The rotation behavior test reflected functional recovery, which may be due to the neurogenesis from neuronally differentiated ADSCs, resulting in a higher pooled effect size of standard mean difference (SMD) (− 2.59; 95% CI, − 3.57 to − 1.61) when compared to that of primitive cells (− 2.18; 95% CI, − 3.29 to − 1.07). Stratified analyses by different time intervals indicated that ADSC intervention exhibited a long-term effect. Following the transplantation of ADSCs, tyrosine hydroxylase-positive neurons recovered in the lesion area with pooled SMD of 13.36 [6.85, 19.86]. Transplantation of ADSCs is a therapeutic option that shows long-lasting effects in animal models of PD. The potential mechanisms of ADSCs involve neurogenesis and neuroprotective effects. The standardized induction of neural form of transplanted ADSCs can lead to a future application in clinical practice.

Research and theorizing suggest two competing—yet untested—hypotheses for how European Americans’ and Asians’ feeling of being “in control” might differ when excluded by a close other (e.g., a good friend). Drawing on different national contexts (i.e., United States, Japan), cultural groups (i.e., Japanese, Asian/Asian Americans, European Americans), and exclusion paradigms (i.e., relived, in vivo), four separate experiments ( N = 2,662) examined feelings of control when excluded by a close- or distant-other. A meta-analysis across these experiments indicated that Asians and Asian Americans felt more in control than European Americans when the excluder was a close other. In contrast, no consistent pattern emerged when the excluder was a distant other. This research has implications for cultural variations in aggressiveness as well as health and well-being following exclusion’s threat to perceived control.

IntroductionScabies is recognised as a neglected tropical disease, disproportionately affecting the most vulnerable populations around the world. Impetigo often occurs secondarily to scabies. Several studies have explored mass drug administration (MDA) programmes, with some showing positive outcomes—but a systematic evaluation of such studies is yet to be reported. The main aim of this systematic review is to generate comprehensive evidence on the effect and feasibility of MDA programmes in reducing the burden of scabies and impetigo.Methods and analysisA systematic review and meta-analysis will be conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. Electronic databases to be searched will include CINAHL EBSCOhost, Medline Ovid, ProQuest, Science Direct, PubMed and SCOPUS. In addition, grey literature will be explored via the Australian Institute of Health and Welfare, Australian Indigenous HealthInfoNet, Informit, OaIster database and WHO. No language restrictions will be applied. All treatment studies following an MDA protocol, including randomised/quasi-controlled trials, and prospective before–after interventional studies, will be considered. The main outcome is the change in prevalence of scabies and impetigo The Cochrane collaboration risk of bias assessment tool will be used for assessing the methodological quality of studies. A random-effect restricted maximum likelihood meta-analysis will be performed to generate pooled effect (OR) using STATA V.16. Appropriate statistical tests will be carried out to quantify heterogeneity between studies and publication bias.Ethics and disseminationEthical approval is not required since data will be extracted from published works. The findings will be communicated to the scientific community through a peer-reviewed journal publication. This systematic review will present an evidence on the effect of MDA interventions on scabies and impetigo, which is instrumental to obtain a clear understanding of the treatments widely used in these programmes.PROSPERO registration numberCRD42020169544,
