ABSTRACTObjectives:More than 90% of individuals with Alzheimer’s disease (AD) experience behavioral and neuropsychiatric symptoms (NPS), such as agitation. However, little is known regarding the specific burden of agitation for Alzheimer’s patients.Design:A global systematic literature review was conducted in MEDLINE and Embase for studies of clinical, humanistic, and economic burden of agitation in AD/dementia published from 2006–2016. References of identified papers and related literature reviews were examined. Studies meeting predetermined inclusion criteria for burden of agitation/NPS were summarized.Results:Eighty papers met the inclusion criteria for burden of agitation in dementia. Wide ranges of agitation prevalence were reported, but few papers provided information on incidence. The association of agitation with AD severity was presented in multiple studies; a few suggested positive association of agitation with mortality.Conclusions:High prevalence of agitation is consistent with earlier reports, but several gaps in understanding of agitation in AD need further exploration.

Background: Withania somnifera has been used as an ergogenic resource in recent years. In this scenario, a systematic literature review is justified to compile the findings in the scientific literature and to evaluate the methodological quality of these investigations. Aims: Our objective with this review was to evaluate the effects of Withania somnifera supplementation on sports performance in physical exercise practitioners. Material and Methods: This systematic literature review with meta-analysis addresses the effects of Withania somnifera supplementation on sports performance. Results: Of the parameters evaluated in the articles, the maximum oxygen uptake was shown to improve significantly in the three studies in which it was evaluated. Maximum strength was not influenced by the supplementation. Conclusions: The results of the present systematic literature review showed evidence that the supplementation of Withania somnifera over 500 mg to 1,250 mg before or after exercise can improve physical performance. Keywords: Withania, Sports, Dietary Supplements, Athletic Performance.

Vegetarianism has been getting increasing attention over the years, in society in general and in sport in particular. However, the growth in the number of people following a meatless diet notwithstanding, vegetarianism should be practiced with caution, especially by professional and recreational athletes, considering the possible lack of certain nutrients and decline in their physical performance. Therefore, the present review aimed to determine whether following a vegetarian diet influences recreational and professional athletes’ physical and sports performance. A search of the databases Medline/Pubmed, Scopus, Web of Science, and Lilacs gave 343 relevant articles; however, only 15 of these focused on the vegetarian diet and physical performance, in accordance with the inclusion criteria. These studies compared the vegetarian diet with the omnivorous diet, and found that it did not negatively influence physical performance. Moreover, those who followed a vegetarian diet seemed to have a higher volume of maximum oxygen (V̇O2 max), which positively influenced their performance. In conclusion, following a plant-based diet does not seem to harm recreational and professional athletes.

INTRODUCTION: Prevalence of sleep bruxism (SB) in children is subject to discussions in the literature.OBJECTIVE: This study is a systematic literature review aiming to critically assess the prevalence of SB in children.METHODS: Survey using the following research databases: MEDLINE, Cochrane, EMBASE, PubMed, Lilacs and BBO, from January 2000 to February 2013, focusing on studies specifically assessing the prevalence of SB in children.RESULTS: After applying the inclusion criteria, four studies were retrieved. Among the selected articles, the prevalence rates of SB ranged from 5.9% to 49.6%, and these variations showed possible associations with the diagnostic criteria used for SB.CONCLUSION: There is a small number of studies with the primary objective of assessing SB in children. Additionally, there was a wide variation in the prevalence of SB in children. Thus, further, evidence-based studies with standardized and validated diagnostic criteria are necessary to assess the prevalence of SB in children more accurately.

The computer science (CS) unplugged approach intends to teach CS concepts and computational thinking skills without employing any digital tools. The current study conducted a systematic literature review to analyze research studies that conducted investigations related to implementations of CS unplugged activities. A systematic review procedure was developed and applied to detect and subsequently review relevant research studies published from 2010 to 2019. It was found that 55 research studies (17 articles + 38 conference proceedings) satisfied the inclusion criteria for the analysis. These research studies were then examined with regard to their demographic characteristics, research methodologies, research results, and main findings. It was found that the unplugged approach was realized and utilized differently among researchers. The majority of the studies used the CS unplugged term when referring to “paper–pencil activities,” “problem solving,” “storytelling,” “games,” “tangible programming,” and even “robotics.”

Abstract Objectives The German Society of Craniomandibular Function and Disorders recommends that patients suffering from temporomandibular dysfunctions should practice sports in order to compensate for everyday stress. This raises the question as to what extent competitive athletes develop temporomandibular dysfunctions or whether their athletic activities protect them. With the present literature review, the authors intend to give an overview of the currently available publications on this topic. Materials and methods A literature research in the PubMed and Google Scholar databases was performed to filter out the currently available publications on the topic ‚sports, and temporomandibular dysfunction. Results Out of 114 available articles, seven met the inclusion criteria. Two other relevant articles were found in the list of references, so that in total, nine publications were picked for the review. In case numbers ranging from eight to 347 subjects, a temporomandibular dysfunction was detected with a prevalence between 11.7% and 100% for athletes and between 11.11% and 14.3% for non-athletes. Different kinds of sports were evaluated, all of them contact sports: basketball, handball, wrestling, boxing, karate, mixed martial arts, field hockey, water polo, and soccer. One study compared athletes with and without consumption of anabolic steroids, regardless of the type of sport. The level of athletic performance varied across the different studies. Conclusions Currently, studies dealing with the effect of competitive sports on temporomandibular dysfunction are scarce. Inconsistent methodological procedures permit only limited comparability. Clinical relevance A general trend, however, can already be discerned: professional athletes suffer from temporomandibular dysfunctions more frequently than non-athletes.

Lack of public support for coastal adaptation can present significant barriers for implementation. In response, policy makers and academics are seeking strategies to build public support for coastal adaptation, which requires a deeper understanding of peoples’ preferences for coastal adaptation and what motives those preferences. Here, we conduct a systematic literature review to understand preferences for coastal adaptation options and the factors influencing these preferences. Ninety peer-reviewed publications meet the inclusion criteria. The findings revealed that hard protection options were often the most frequently preferred, likely due to a desire to maintain current shoreline, for the protection of recreational spaces and private property, and a perceived effectiveness of hard protection options. Soft protection, including nature-based approaches, accommodation, and no action were the next most preferred options. Finally, retreat options were the least preferred, often due to strong place attachment. We identify twenty-eight factors that could influence preferences, with risk perception, place attachment, and financial considerations occurring most frequently in the literature. In the conclusion, we outline the most significant research gaps identified from our analysis and discuss the implication for adaptation research and practice.

The Impact

The majority of studies that analyze the impact of entrepreneurship education on entrepreneurial attitudes, intentions, and venture activities report positive influences. However, several scholars have recently cast doubts about research methods and the generalizability of entrepreneurship education impact studies. In this study, we conducted a systematic literature review of the methods used in entrepreneurship education impact studies. Our results uncover significant methodological deficiencies and question the overwhelmingly positive impact of entrepreneurship education. Based on this evidence, we propose a series of recommendations to improve the reliability and validity of entrepreneurship education impact studies and we outline promising topics which are currently under-researched.

Mixed Dentition Analysis

INTRODUCTION: Moyers analysis is widely used for analyzing mixed dentition, however, the accuracy of its theoretical probability tables has been recently questioned. Taking into consideration the fact the mixed dentition analysis is of paramount importance to precisely determine the space needed for alignment of canines and premolars, this research aimed at objectively assessing in the literature such an important step for orthodontic diagnosis. METHODS: A computerized search involving articles published on PubMed and Lilacs between 1990 and September, 2011 was conducted in accordance with the method described in the Cochrane 5.1.0 handbook. RESULTS: The research resulted in a sample composed of 629 articles. The inclusion criteria were: Articles using the Moyers analysis with a sample greater or equal to 40 patients. Conversely, the exclusion criteria were: Dental casts of patients with syndromes or oral cleft, researches conducted with a literature review, only, or clinical case reports and researches conducted before 1990. For this systematic review, 19 articles were selected. CONCLUSION: Based on the literature available, we can conclude that the Moyers mixed dentition analysis must be carefully used, since the majority of the articles analyzed showed that the probability of 75% was not as accurate as expected, leading to the need of adapting the probability levels depending on the study population.

Surgical Treatments

Despite the large number of available surgical interventions aimed at the treatment of rectovaginal fistulas, the results of their use remain extremely disappointing, associated with the high recurrence rate of the disease reaching 80 %, as well as the lack of a single tactic to minimize the risk of anal incontinence and the need for colostomy. Objective: to conduct a systematic literature review in order to summarize information related to the rectovaginal fistulas surgery. The systematic review includes the results of an analysis of 97 clinical trials selected from 756 publications found in databases. Inclusion criteria: a full-text article, the presence of at least 5 patients in the study, as well as data on the outcome of surgery. Clinical trials with different surgical treatments were identified and classified into the following categories: elimination of the rectovaginal septal defect with a displaced flap (rectal and vaginal); Martius surgery; gracilis muscle transposition; transperineal procedure; abdominal procedure including endoscopic and laparoscopic methods; use of biological or biocompatible materials. Treatment outcomes vary significantly from 0 % to > 80 %. None of the studies were randomized. Due to the low quality of the identified studies, comparison of results and meta-analysis conduction were not possible. Conclusion: as a result of the systematic review, data for the analysis and development of any strategic and tactical algorithms for the treatment of RVF were not obtained. The most important questions still remain open: what and when surgical method to choose, is it necessary to form a disconnecting stoma?
