The study aimed to systematically analyze the empirical evidence that is available concerning batteries, tests or instruments that assess hot executive functions (EFs) in preschoolers, identifying which are the most used instruments, as well as the most evaluated hot EFs. For the review and selection of articles, the systematic review methodology PRISMA was used. The article search considered the EBSCO, Web of Science (WoS), SciELO and PubMed databases, with the keywords “Hot executive function”, “Assessment”, “test”, “evaluation”, using the Boolean operators AND and OR indistinctly, between 2000 and April 2021. Twenty-four articles were selected and analyzed. The most commonly used instruments to assess hot EFs in preschool children were the Delayed Gratification Task, the Child’s Play Task, and the Delayed Reward Task. Amongst those analyzed, 17 instruments were found to assess hot EFs in preschoolers. The accuracy and conceptual clarity between the assessment of cognitive and emotional components in EFs is still debatable. Nevertheless, the consideration of affective temperature and reward stimulus type, could be an important influence when assessing EFs in this age range. Evidence of the possible involvement of cortical and subcortical structures, as well as the limbic system, in preschool executive functioning assessment has also been incorporated.

The Impact

Background Early identification of preschool children who are at risk of faltering in their development is essential to ensuring that all children attain their full potential. Electroencephalography (EEG) has been used to measure neural correlates of cognitive and social development in children for decades. Effective portable and low-cost EEG devices increase the potential of its use to assess neurodevelopment in children at scale and particularly in low-resource settings. We conducted a systematic review aimed to synthesise EEG measures of cognitive and social development in 2-5-year old children. Our secondary aim was to identify how these measures differ across a) the course of development within this age range, b) gender and c) socioeconomic status (SES). Methods and findings A systematic literature search identified 51 studies for inclusion in this review. Data relevant to the primary and secondary aims was extracted from these studies and an assessment for risk of bias was done, which highlighted the need for harmonisation of EEG data collection and analysis methods across research groups and more detailed reporting of participant characteristics. Studies reported on the domains of executive function (n = 22 papers), selective auditory attention (n = 9), learning and memory (n = 5), processing of faces (n = 7) and emotional stimuli (n = 8). For papers investigating executive function and selective auditory attention, the most commonly reported measures were alpha power and the amplitude and latency of positive (P1, P2, P3) and negative (N1, N2) deflections of event related potential (ERPs) components. The N170 and P1 ERP components were the most commonly reported neural responses to face and emotional faces stimuli. A mid-latency negative component and positive slow wave were used to index learning and memory, and late positive potential in response to emotional non-face stimuli. While almost half the studies described changes in EEG measures across age, only eight studies disaggregated results based on gender, and six included children from low income households to assess the impact of SES on neurodevelopment. No studies were conducted in low- and middle-income countries. Conclusion This review has identified power across the EEG spectrum and ERP components to be the measures most commonly reported in studies in which preschool children engage in tasks indexing cognitive and social development. It has also highlighted the need for additional research into their changes across age and based on gender and SES.

Evidence Based Decision Making

Big international development donors such as the UK’s Department for International Development and USAID have recently started using systematic review as a methodology to assess the effectiveness of various development interventions to help them decide what is the ‘best’ intervention to spend money on. Such an approach to evidence-based decision-making has long been practiced in the health sector in the US, UK, and elsewhere but it is relatively new in the development field. In this article we use the case of a systematic review of the impact of microfinance on the poor in sub-Saharan African to indicate how systematic review as a methodology can be used to assess the impact of specific development interventions.

BACKGROUND The increasing screen time exposure among young children in general and the reported negative consequences associated with excessive ST, calls for focused strategies to reduce ST, especially among young children. OBJECTIVE This systematic review aimed to identify effective parental intervention strategies to reduce ST among preschool children. METHODS A total of five databases, namely Cochrane Central Register of Controlled Trials, CINAHL, Medline Complete, PubMed, and Scopus, were searched for randomised controlled trials that involved intervention strategies in ST reduction among preschool children. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines were used. RESULTS A total of nine studies were assessed. The results showed that besides providing knowledge and awareness regarding ST, having restrictive practices, offering alternative activities to parents, and removal of screen from child’s bedroom were the most common strategies used by studies that reported successful intervention. Intervention duration of between six to eight weeks was sufficient to produce ST reduction. Face-to-face method was the commonest mode of delivery. Theoretical constructs that aimed at increasing parental self-efficacy, listing outcome expectations, and offering reinforcement of strategies that targeted both the parents and home environment were beneficial in reducing ST. CONCLUSIONS By offering appropriate strategies to parents, a reduction in the amount of ST was observed among the children. Future intervention studies could benefit in exploring culturally adapted strategies, especially in developing countries. Trials of higher quality would also facilitate the drawing of conclusions in future research. CLINICALTRIAL PROSPERO No: CRD42020199398

<b><i>Background:</i></b> Histopathological analysis can provide additional clues in COVID-19 understanding. During the last year, autopsy reports have revealed that diffuse alveolar damage (DAD) is the most significant observed finding. The aim of this study is to review cases in the literature about COVID-19 autopsies that reported microthrombi in different organs. <b><i>Methods:</i></b> We performed a systematic literature review in PubMed, Virtual Health Library (VHL), and Google Scholar. <b><i>Results:</i></b> In total, 151 autopsies were included, and 91 cases presented microthrombi in the lung (73%), heart (11.2%), kidney (24%), and liver (16.3%). The age range was between 27 and 96 years. Males were 64.8%. The patients with microthrombi had more comorbidities such as arterial hypertension (62%), obesity or overweight (64%), diabetes mellitus type 2 (51%), and heart disease (53%). The most common histopathological changes found in patients with lung microthrombosis were DAD in exudative phase (78%), pulmonary embolism (59%), and lung infarct (81%). Presence of microthrombi was associated with arterial hypertension (<i>p</i> &#x3c; 0.0001) and DAD in exudative and proliferative phases (<i>p</i> = 0.02). <b><i>Discussion:</i></b> The analysis of these results shows that microthrombi in COVID-19 autopsies may be found in different organs and are more frequent in patients with comorbidities, pulmonary embolism, and lung infarct.

The Impact

One of the most studied aspects of children’s cognitive development is that of the development of the executive function, and research has shown that physical activity has been demonstrated as a key factor in its enhancement. This meta-analysis aims to assess the impact of specific sports interventions on the executive function of children and teenagers. A systematic review was carried out on 1 November 2020 to search for published scientific evidence that analysed different sports programs that possibly affected executive function in students. Longitudinal studies, which assessed the effects of sports interventions on subjects between 6 and 18 years old, were identified through a systematic search of the four principal electronic databases: Web of Science, PubMed, Scopus, and EBSCO. A total of eight studies, with 424 subjects overall, met the inclusion criteria and were classified based on one or more of the following categories: working memory, inhibitory control, and cognitive flexibility. The random-effects model for meta-analyses was performed with RevMan version 5.3 to facilitate the analysis of the studies. Large effect sizes were found in all categories: working memory (ES −1.25; 95% CI −1.70; −0.79; p < 0.0001); inhibitory control (ES −1.30; 95% CI −1.98; −0.63; p < 0.00001); and cognitive flexibility (ES −1.52; 95% CI −2.20; −0.83; p < 0.00001). Our analysis concluded that healthy children and teenagers should be encouraged to practice sports in order to improve their executive function at every stage of their development.

ObjectiveThis systematic review aimed to explore consultant attitudes towards teaching undergraduate medical students in the UK.DesignSystematic review.MethodologyStandard systematic review methodology was followed. MEDLINE, EMBASE and OpenGrey were searched from inception to August 2019 to identify studies exploring senior doctors’ attitudes towards teaching undergraduate medical students. Two reviewers independently carried out key methodological steps including study screening/selection, quality assessment and data extraction. A narrative synthesis was undertaken.ResultsFive studies were included in the review dating 2003–2015. Two studies used questionnaires, and three used focus groups/semistructured interviews. Key findings identified across all studies were consultants generally found teaching undergraduate medical students enjoyable, and consultants identified time constraints as a barrier to teaching. Other findings were consultants feeling there was a lack of recognition for time spent teaching, and a lack of training/guidance regarding teaching students.ConclusionsThis is the first systematic review to explore senior hospital doctors’ attitudes towards teaching undergraduate medical students. Despite these five studies spanning 12 years, the same attitudes and issues regarding teaching are identified by all, suggesting lack of time particularly is a persistent problem regarding consultant-based teaching. An anecdotal impression is that consultants are no longer as enthusiastic about teaching as they once were, but it is evident over the 12 years of these studies that enjoyment levels, and presumably enthusiasm, have not changed significantly.
