Resurrection plants have an extraordinary ability to survive extreme water loss but still revive full metabolic activity when rehydrated. These plants are useful models to understand the complex biology of vegetative desiccation tolerance. Despite extensive studies of resurrection plants, many details underlying the mechanisms of desiccation tolerance remain unexplored. To summarize the progress in resurrection plant research and identify unexplored questions, we conducted a systematic review of 15 model angiosperm resurrection plants. This systematic review provides an overview of publication trends on resurrection plants, the geographical distribution of species and studies, and the methodology used. Using the Preferred Reporting Items for Systematic reviews and Meta–Analyses protocol we surveyed all publications on resurrection plants from 2000 and 2020. This yielded 185 empirical articles that matched our selection criteria. The most investigated plants were Craterostigma plantagineum (17.5%), Haberlea rhodopensis (13.7%), Xerophyta viscosa (reclassified as X. schlechteri) (11.9%), Myrothamnus flabellifolia (8.5%), and Boea hygrometrica (8.1%), with all other species accounting for less than 8% of publications. The majority of studies have been conducted in South Africa, Bulgaria, Germany, and China, but there are contributions from across the globe. Most studies were led by researchers working within the native range of the focal species, but some international and collaborative studies were also identified. The number of annual publications fluctuated, with a large but temporary increase in 2008. Many studies have employed physiological and transcriptomic methodologies to investigate the leaves of resurrection plants, but there was a paucity of studies on roots and only one metagenomic study was recovered. Based on these findings we suggest that future research focuses on resurrection plant roots and microbiome interactions to explore microbial communities associated with these plants, and their role in vegetative desiccation tolerance.

It is crucial that special education teachers are equipped with the knowledge and skills necessary to improve outcomes for students with disabilities. Despite federal legislation and efforts of the field to identify and disseminate evidence-based practices for students with disabilities, it is uncertain whether all special education teachers provide instruction based on the best available research. To better prepare special education teachers, McLeskey et al. proposed 22 high-leverage practices (HLPs). We conducted this systematic review of meta-analyses to provide an initial investigation of the experimental evidence reporting on the effectiveness of the HLPs for students with, or at risk for, a disability. Results indicated the largest amount of evidence from meta-analyses related to intensive instruction, explicit instruction, and social skills, with few meta-analyses reporting on collaboration and assessment. The results highlighted disproportional evidence according to disability categories. Implications for future research, practice, and teacher education are discussed.

AbstractBackgroundOrthorexia Nervosa (ON) and exercise addiction (ExAdd) are two phenomena believed to overlap. We conducted a meta-analysis exploring the link between ON and (addictive) exercise behaviors.MethodsA systematic review of major databases and gray literature was carried out for studies reporting on ON and (addictive) exercise behaviors. Random effects meta-analyses were undertaken calculating correlations between ON and (addictive) exercise behaviors. A sub-group analysis investigated gender differences.ResultsTwenty-five studies with 10,134 participants (mean age = 25.21; 56.4% female) were included. Analyses showed a small overall correlation between ON and exercise (21 studies, r = 0.12, 95% CI |0.06–0.18|) and a medium overall correlation between ON and ExAdd (7 studies, r = 0.29, 95% CI |0.13–0.45|). Gender differences were negligible.ConclusionsOrthorexic eating correlated slightly and moderately with exercise and ExAdd, respectively, expressing some unique and shared variance of these behaviors. While this does not suggest ON and addictive exercising to be independent, it does not indicate substantial comorbidity. Future research should focus on clinical relevance, underlying mechanisms, vulnerability, and risk factors.

Background: To develop evidence-based anti-stigma programmes for adolescents, underlying factors that drive dementia-related stigma in adolescents need to be captured. However, it is unclear which factors play a role in dementia attitude formation in adolescents. This is a protocol for a systematic review that will seek to identify factors associated with dementia attitudes in adolescents (10-18 years old). Methods: A systematic search strategy will be used to identify observational data in which factors are associated with dementia-related stigma and associated domains (e.g. attitudes, beliefs, perceptions). Systematic searches for articles will be conducted in the following databases: PubMed, PsycInfo, Web of Science, SCOPUS and Open Access Theses and Dissertations. Titles and abstracts will be screened with the assistance of machine learning software (ASReview), prior to reviewing full texts. Following data extraction, quality assessment of study and risk of bias will be assessed using the mixed methods appraisal tool (MMAT). The protocol is written in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocol (PRISMA-P) guidelines. Results: Descriptive data of the studies will be reported in tables and summarised narratively and split into thematic headings guided by the results of the systematic review. Identifying which factors are implicated in attitudes towards people living with dementia will allow researchers to be better informed in which factors may be a useful target for more tailored and effective dementia related anti-stigma-initiatives. Discussion: The findings from this systematic review will help guide future research to identify groups that may be at the greatest risk of developing stigmatising attitudes and potential targets for future intervention.

Meta Analyses

A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), to generate a document that supports the development of future research, compiling the various studies focused on the analysis of the pedestrian-vehicle interaction at unsignalized crosswalks. Firstly, 381 studies were identified by applying the search protocol in the database sources; however, only nine studies were included in this review because most of the studies are not focused on this type of crosswalks or have not considered the micro-simulation perspective. For each study, an analysis of the used methodology for data collection was carried out, in addition to what type of model it was applied, including the variables that represent the PVI (Pedestrian-Vehicle Interaction). The outcomes obtained by this systematic review show that although the video camera observation technique is the most used, it is possible to complement them with other tools to add specific field information. Additionally, variables such as the adjacent yields, speed variables vehicles, pedestrian attitude, and the number of pedestrians waiting at the crossing were those most used in the cellular automata model or micro-simulation, which are the commonly developed models to simulate this interaction.

Aim: To perform a review of network meta-analyses (NMAs) for the first-line treatment of EGFR mutation-positive non-small-cell lung cancer, and to provide an overview of methodological approaches and potential shortcomings. Materials & methods: We conducted a systematic review of NMAs and evaluated their methodologies, including inclusion/exclusion criteria, information sources, results and outcomes, and statistical methodologies. Results: We identified ten published NMAs using five archetypical network structures. Despite similar objectives, there was substantial variability in the number of trials included in each NMA and in the relative treatment efficacy of the tyrosine kinase inhibitors. Conclusion: We identified methodological issues to explain differences in the findings, criteria for inclusion in NMAs and the degree of lumping of treatments. These factors should be given particular consideration in future research.

Meta Analyses

A systematic review was completed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search of four electronic databases (2004–2015) yielded 60,017 articles, of which 29 met inclusion criteria. Included studies performed poorly on data quality analysis in terms of randomisation and controlling for confounding factors. Participant’s body mass index scores range from 19.73 (standard deviation = 1.54) to 28.4 (standard deviation = 1.4) kg/m2. Where positive and negative affects were compared, food was more likely to be consumed in response to positive affect. With regard to discrete emotions; stress, depression and sadness consistently elicited eating behaviours that fall outside of nutritional recommendations (e.g. increased food intake or poor nutritional food choices). The role of moderators including individual differences in dietary restraint and emotional eating, as well as methodological considerations, such as means of eliciting and measuring emotions, may account for equivocality with regard to some emotion and eating associations. This article concludes with recommendations for future research and implications for practice.

Effect Of Age

Abstract This systematic review and meta-analysis quantifies the magnitude and breadth of age-related differences in trust. Thirty-eight independent data sets met criteria for inclusion. Overall, there was a moderate effect of age group on trust (g = 0.22), whereby older adults were more trusting than young adults. Three additional meta-analyses assessed age-related differences in trust in response to varying degrees of trustworthiness. This revealed that older adults were more trusting than young adults in response to neutral (g = 0.31) and negative (g = 0.33), but not positive (g = 0.15), indicators of trustworthiness. The effect of age group on trust in response to positive and neutral cues was moderated by type of trust (financial vs. non-financial) and type of responding (self-report vs. behavioral). Older adults were more trusting than young adults in response to positive and neutral indicators of trustworthiness when trust was expressed non-financially, but not financially. There was also an age-related increase in self-reported, but not behavioral, trust in response to neutral cues. Older adults were more trusting than young adults in response to negative indicators of trustworthiness regardless of the type of trust or type of responding. The reliability of information about trustworthiness (superficial vs. genuine cues) did not moderate any effects of age on trust. Implications of these findings and directions for future research are discussed.

Objective Assess the effect of non-pharmacological alcohol interventions on reducing heavy episodic drinking (HED) outcomes in sub-Saharan Africa. Methods A systematic review of the available literature through August 19, 2020 was conducted. Randomized and non-randomized controlled trials testing non-pharmacological interventions on alcohol consumption in sub-Saharan Africa were eligible for inclusion. Eligible outcomes included measures of HED/binge drinking, and measures indicative of this pattern of drinking, such as high blood alcohol concentration or frequency of intoxication. Three authors extracted and reconciled relevant data and assessed risk of bias. The review protocol is available on PROSPERO (registration number: CRD42019094509). The Cochrane Handbook recommendations for the review of interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines guided all methodology. Results Thirteen intervention trials were identified that met our inclusion criteria and measured change in HED. Studies were judged of moderate quality. A beneficial effect of non-pharmacological interventions on HED was reported in six studies, three of which were deemed clinically significant by the review authors; no statistically significant effects were identified in the other seven studies. Interventions achieving statistical and/or clinical significance had an intervention dose of two hours or greater, used an array of psychosocial approaches, including Motivational Interviewing integrated in Brief Intervention, cognitive behavioral therapy and integrated risk reduction interventions, and were delivered both individually and in groups. Conclusions Evidence for the effectiveness of non-pharmacological interventions to reduce HED in sub-Saharan African settings was limited, demonstrating the need for more research. To strengthen the literature, future research should employ more rigorous study designs, improve consistency of HED measurement, test interventions developed specifically to address HED, and explore structural approaches to HED reduction.
