Tinjauan kritis dari tulisan ini memberikan kritisi dimaksudkan untuk melihat kekurangan dari artikel ilmiah yang berjudul Pengembangan dan Evaluasi Formatif Studi kasus Multimedia untuk Siswa Desain dan Teknology Pembelajaran.  Tinjauan kritis yang dilakukan diungkapkan dengan sepenuhnya mengacu pada teori dan fakta buku-buku referensi dan jurnal ilmiah yang relevan. Hasil tinjauan kritis memperlihatkan beberapa kelemahan dari artikel ilmiah tersebut, diantaranya adalah:  artikel tersebut terpaku pada desain pembelajaran dan produksi multimedia, dan tidak ada acuan model atau pendekatan sistem desain pembelajaran, sehingga terjadi bias. Padahal setiap pengembangan pembelajaran (Instructional Development) sama artinya dengan mengembangkan model pembelajaran yang ada meliputi proses  perencanaan, pemilihan strategi pembelajaran, pemilihan media, dan pemilihan/pembuatan bahan, dan evaluasi. Penulis artikel ilmiah tersebut tidak melihat bahwa selain desain pembelajaran dan produksi multimedia ada satu hal penting lagi yang harus dilihat adalah permintaan khusus dari klien atau sama artinya dengan kebutuhan yang ingin dicapai pada desain/rancangan multimedia/produksi multimedia. Penulis artikel ilmiah tersebut seakan-akan desain pembelajaran dan produksi multimedia sebagai dua bagian yang berdiri sendiri, padahal merupakan satu kesatuan yang tak terpisahkan jika didasarkan pada pada berbagai model desain dan implementasi model multimedia yang dikenalkan oleh berbagai ahli, misalnya pada  model pembelajaran ADDIE, Dick & Carey, Minerva, dan AT & T Instructional Development produksi multimedia adalah bagian dari perancangan pembelajaran/desain pembelajaran; kegiatan desain pembelajaran dan/atau produksi multimedia; hanya satu tema media yang muncul yaitu: penggunaan video (video use), padahal komponen  multimedia terdiri dari teks, audio, visual (gambar, foto, grafik), dan video.

Tenecteplase is a fibrinolytic drug with higher fibrin specificity and longer half-life than the standard stroke thrombolytic, alteplase, permitting the convenience of single bolus administration. Tenecteplase, at 0.5 mg/kg, has regulatory approval to treat ST-segment–elevation myocardial infarction, for which it has equivalent 30-day mortality and fewer systemic hemorrhages. Investigated as a thrombolytic for ischemic stroke over the past 15 years, tenecteplase is currently being studied in several phase 3 trials. Based on a systematic literature search, we provide a qualitative synthesis of published stroke clinical trials of tenecteplase that (1) performed randomized comparisons with alteplase, (2) compared different doses of tenecteplase, or (3) provided unique quantitative meta-analyses. Four phase 2 and one phase 3 study performed randomized comparisons with alteplase. These and other phase 2 studies compared different tenecteplase doses and effects on early outcomes of recanalization, reperfusion, and substantial neurological improvement, as well as symptomatic intracranial hemorrhage and 3-month disability on the modified Rankin Scale. Although no single trial prospectively demonstrated superiority or noninferiority of tenecteplase on clinical outcome, meta-analyses of these trials (1585 patients randomized) point to tenecteplase superiority in recanalization of large vessel occlusions and noninferiority in disability-free 3-month outcome, without increases in symptomatic intracranial hemorrhage or mortality. Doses of 0.25 and 0.4 mg/kg have been tested, but no advantage of the higher dose has been suggested by the results. Current clinical practice guidelines for stroke include intravenous tenecteplase at either dose as a second-tier option, with the 0.25 mg/kg dose recommended for large vessel occlusions, based on a phase 2 trial that demonstrated superior recanalization and improved 3-month outcome relative to alteplase. Ongoing randomized phase 3 trials may better define the comparative risks and benefits of tenecteplase and alteplase for stroke thrombolysis and answer questions of tenecteplase efficacy in the >4.5-hour time window, in wake-up stroke, and in combination with endovascular thrombectomy.

Background Central line-associated bloodstream infections (CLABSIs) are preventable complications that pose a significant health risk to patients and place a financial burden on hospitals. Central line simulation-based education (SBE) efforts vary widely in the literature. The aim of this study was to perform a value analysis of published central line SBE and develop a refined method of studying central line SBE. Methods A database search of PubMed Central and Cumulative Index to Nursing and Allied Health Literature (CINAHL) was performed for articles mentioning “Cost and CLABSI,” “Cost and Central line Associated Bloodstream Infections,” and “Cost and Central Line” in their abstract and article body. Articles chosen for qualitative synthesis mentioned “simulation” in their abstract and article body and were analyzed based on the following criteria: infection rate before vs. after SBE, cost of simulation, SBE design including simulator model used, and learner analysis. Results Of 215 articles identified, 23 were analyzed, 10 (43.48%) discussed cost of central line simulation with varying criteria for cost reporting, 8 (34.8%) numerically discussed central line complication rates (7 CLABSIs and 1 pneumothorax), and only 3 (13%) discussed both (Figure). Only 1 addressed the true cost of simulation (including space rental, equipment startup costs, and faculty salary) and its longitudinal effect on CLABSIs. Conclusion Current literature on central line SBE efforts lacks value propositions. Due to the lack of value-based data in the area of central line SBE, the authors propose a cost reporting standard for use by future studies reporting central line SBE costs.

IntroductionThere is a growing concern about the misuse of over the counter (OTC) and prescription only medication (POM) because of the impact on physical and mental health, drug interactions, overdoses and drug-related deaths. These medicines include opioid analgesics, anxiolytics such as pregabalin and diazepam and antidepressants. This protocol outlines how a systematic review will be undertaken (during June 2021), which aims to examine the literature on the pattern of OTC and POM misuse among adults who are accessing substance misuse treatment services. It will include the types of medication being taken, prevalence and demographic characteristics of people who access treatment services.Methods and analysisAn electronic search will be conducted on the Cochrane, OVID Medline, Pubmed, Scopus and Web of Science databases as well as grey literature. Two independent reviewers will conduct the initial title and abstract screenings, using predetermined criteria for inclusion and exclusion. If selected for inclusion, full-text data extraction will be conducted using a pilot-tested data extraction form. A third reviewer will resolve disagreements if consensus cannot be reached. Quality and risk of bias assessment will be conducted for all included studies. A qualitative synthesis and summary of the data will be provided. If possible, a meta-analysis with heterogeneity calculation will be conducted; otherwise, Synthesis Without Meta-analysis will be undertaken for quantitative data. The reporting of this protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.Ethics and disseminationEthical approval is not required. Findings will be peer reviewed, published and shared verbally, electronically and in print, with interested clinicians and policymakers.PROSPERO registration numberCRD42020135216.

Abstract Background/Objective Movement integration (MI) involves infusing physical activity into normal classroom time. A wide range of MI interventions have succeeded in increasing children’s participation in physical activity. However, no previous research has attempted to unpack the various MI intervention approaches. Therefore, this study aimed to systematically review, qualitatively analyze, and develop a typology of MI interventions conducted in primary/elementary school settings. Subjects/Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed to identify published MI interventions. Irrelevant records were removed first by title, then by abstract, and finally by full texts of articles, resulting in 72 studies being retained for qualitative analysis. A deductive approach, using previous MI research as an a priori analytic framework, alongside inductive techniques were used to analyze the data. Results Four types of MI interventions were identified and labeled based on their design: student-driven, teacher-driven, researcher-teacher collaboration, and researcher-driven. Each type was further refined based on the MI strategies (movement breaks, active lessons, other: opening activity, transitions, reward, awareness), the level of intrapersonal and institutional support (training, resources), and the delivery (dose, intensity, type, fidelity). Nearly half of the interventions were researcher-driven, which may undermine the sustainability of MI as a routine practice by teachers in schools. An imbalance is evident on the MI strategies, with transitions, opening and awareness activities, and rewards being limitedly studied. Delivery should be further examined with a strong focus on reporting fidelity. Conclusions There are distinct approaches that are most often employed to promote the use of MI and these approaches may often lack a minimum standard for reporting MI intervention details. This typology may be useful to effectively translate the evidence into practice in real-life settings to better understand and study MI interventions.

Abstract Background/Aims  Fatigue has been reported by young people and professionals alike as a major challenge for people living with juvenile idiopathic arthritis (JIA) . It remains unclear as to how therapeutic interventions impacts on this major symptom. The aim of this review was to determine the current evidence for the effectiveness of therapeutic interventions, non- pharmacological and pharmacological, on improving fatigue in adolescents with JIA. Methods  Three electronic databases (MEDLINE, EMBASE, PsycINFO) were searched from 2000 to Feb 2020; in addition to manual searches. Articles were eligible for inclusion if they (i) were original research papers, (ii) had fatigue as a primary outcome measure (iii) included adolescents (10-25 years) and (iv) were available in the English language. Results  Of the 3,142 records identified, 31 underwent full text assessment and 4 studies were included in the qualitative synthesis including 2 from the Netherlands, 1 Germany, and 1 from Canada. The total number of participants across the 4 studies was 824. Three were randomised controlled trials of nonpharmacological interventions and one was a cohort study from a national drug registry including older adolescents JIA (mean: 19-years). Measurement tools included the Paediatric Quality of life multidimensional fatigue scale, (2 studies), the Checklist for Individual Strength CIS-20 (1 study), a numeric rating scale (1 study). In one study a visual analogue scale for energy level was also utilised. In 2 studies baseline prevalence of fatigue was reported as 60% and 76% respectively. Significant reduction in fatigue was observed in all three nonpharmacological studies. In the registry study, fatigue was noted to be prevalent in spite of the disease being in inactive or minimally active on biologic therapy. In 3 studies the relationship between health-related quality of life and fatigue was highlighted and showed a decreased quality of life in fatigued young people. Conclusion  Fatigue is a significant problem in JIA during adolescence and influences quality of life. Improvements in fatigue with non-pharmacological interventions have been reported. However, at present, data is insufficient to conclusively decide which treatment intervention is most efficacious in treating fatigue in young people with JIA. Fatigue should be considered as an important outcome measure for the management of JIA in future evaluations of interventions. Disclosure  S. Moshtael: None. S. Khanom: None. J.E. McDonagh: None.

Objective: To evaluate all available evidence on the prediction of rotational tooth movements with aligners. Data sources: Seven databases of published and unpublished literature were searched up to 4 August 2020 for eligible studies. Data selection: Studies were deemed eligible if they included evaluation of rotational tooth movement with any type of aligner, through the comparison of software-based and actually achieved data after patient treatment. Data extraction and data synthesis: Data extraction was done independently and in duplicate and risk of bias assessment was performed with the use of the QUADAS-2 tool. Random effects meta-analyses with effect sizes and their 95% confidence intervals (CIs) were performed and the quality of the evidence was assessed through GRADE. Results: Seven articles were included in the qualitative synthesis, of which three contributed to meta-analyses. Overall results revealed a non-accurate prediction of the outcome for the software-based data, irrespective of the use of attachments or interproximal enamel reduction (IPR). Maxillary canines demonstrated the lowest percentage accuracy for rotational tooth movement (three studies: effect size = 47.9%; 95% CI = 27.2–69.5; P < 0.001), although high levels of heterogeneity were identified (I2: 86.9%; P < 0.001). Contrary, mandibular incisors presented the highest percentage accuracy for predicted rotational movement (two studies: effect size = 70.7%; 95% CI = 58.9–82.5; P < 0.001; I2: 0.0%; P = 0.48). Risk of bias was unclear to low overall, while quality of the evidence ranged from low to moderate. Conclusion: Allowing for all identified caveats, prediction of rotational tooth movements with aligner treatment does not appear accurate, especially for canines. Careful selection of patients and malocclusions for aligner treatment decisions remain challenging.

(1) Background: The objective is to systematically review the evidence on intervention programs aiming at reducing inequality in dental caries among children. (2) Methods: Two independent investigators searched MEDLINE, Cochrane library, and Ovid up to December 2020 to identify intervention studies assessing the impact on socioeconomic inequalities in dental caries among children. The interventions included any health promotion/preventive intervention aiming at reducing caries among children across different socioeconomic groups. Comparison groups included children with alternative or no intervention. Cochrane criteria were used to assess interventional studies for risk of bias. (3) Results: After removal of duplicate studies, 1235 articles were retained. Out of 43 relevant papers, 13 articles were identified and used in qualitative synthesis, and reported quantifiable outcomes. The included studies varied in measurements of interventions, sample size, age groups, and follow-up time. Five studies assessed oral health promotion or health-education, four assessed topical fluorides, and four assessed water fluoridation. Interventions targeting the whole population showed a consistent reduction of socioeconomic inequalities in dental caries among children. (4) Conclusion: The quality of included papers was moderate. High heterogeneity did not allow aggregation of the findings. The overall findings suggest that whole population interventions such as water fluoridation are more likely to reduce inequalities in children’s caries than target population and individual interventions.
