The prevention of trauma is important not only because of the expressive and growing prevalence of this injury, but also because of the high impact on quality of life in terms of physical, psychological and social discomfort, negatively interfering in the athlete's life and career. The use of mouthguards (PB) is an important intraoral device used by athletes, especially those with high performance, with the objective of preventing dental and facial trauma during sports practice. In addition, some studies point to the advantage of using (BP) related to occlusal stability and muscle synergism that can influence muscle strength gain. However, some athletes still resist using it because they believe it can negatively influence their performance. The aim of this study was to analyze the acute effect of the use of mouthguards on muscle strength performance through a systematic review. An extensive article searchwas performed, with only articles published before May 2021, using PubMed, Scopus, Web of Science, Latin American, and Caribbean Health Science Literature (LILACS) databases. 12 studies were selected for this systematic review. Five of the selected articles revealed that the use of mouthguard had significant beneficial effects on anaerobic performance tests, six showed no significant difference and only one had a negative impact. It is concluded that the present study supports and defends the use of mouthguards in athletes so that their performance is not affected.

Background: Self-care is essential for the prevention of complications in patients with diabetes, but several authors report that even with health education programs, the incidence of complications in patients with diabetes continues to increase. Objective: We aimed to examine adherence to self-care strategies and the repercussions of adherence on the clinical profiles of individuals with type 2 diabetes. Methods: We performed a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. We searched for related studies in 4 databases: PubMed, Web of Science, Scopus, and Latin American and Caribbean Health Science Literature (LILACS). We included observational studies in English and Portuguese that evaluated the effects of selfcare in individuals with type 2 diabetes. Results: The search resulted in the identification of 615 articles, of which 34 met all the inclusion criteria. General self-care was considered unsatisfactory. Physical exercise was classified as the self-care activity that was performed less frequently by individuals with type 2 diabetes mellitus; adherence to medication was the most frequent behavior among volunteers. Conclusion: The studies indicated poor adherence of the population to good self-care practices, reflected by the increase in complications related to DM.

IntroductionClubfoot is a common congenital birth defect, with an average prevalence of approximately 1 per 1000 live births, although this rate is reported to vary among different countries around the world. If it remains untreated, clubfoot causes permanent disability, limits educational and employment opportunities, and personal growth. The aim of this systematic review and meta-analysis is to estimate the global birth prevalence of congenital clubfoot.Methods and analysisElectronic databases including MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Global Health, Latin American & Caribben Health Science Literature (LILACS), Maternity and Infant Care, Web of Science, Scopus and Google Scholar will be searched for observational studies based on predefined criteria and only in English language from inception of database in 1946 to 10 November 2017. A standard data extraction form will be used to extract relevant information from included studies. The Joanna Briggs Institute appraisal checklist will be used to assess the overall quality of studies reporting prevalence. All included studies will be assessed for risk of bias using a tool developed specifically for prevalence studies. Forest plots will be created to understand the overall random effects of pooled estimates with 95% CIs. An I2test will be done for heterogeneity of the results (P>0.05), and to identify the source of heterogeneity across studies, subgroup or meta-regression will be used to assess the contribution of each variable to the overall heterogeneity. A funnel plot will be used to identify reporting bias, and sensitivity analysis will be used to assess the impact of methodological quality, study design, sample size and the impact of missing data.Ethics and disseminationThis review will be conducted completely based on published data, so approval from an ethics committee or written consent will not be required. The results will be disseminated through a peer-reviewed publication and relevant conference presentations.PROSPERO registration numberCRD42016041922.

IntroductionThere are numerous new systemic treatments for atopic dermatitis in various stages of development and most are being compared with placebo rather than active comparators. In order to understand the relative efficacy and safety of existing and new treatments for atopic dermatitis, robust mixed comparisons (ie, direct and indirect) would be beneficial. To address this gap, this protocol describes methods for a systematic review and network meta-analysis of systemic treatments for atopic dermatitis.Methods and analysisWe will update the search of a previous systematic review, including searches of the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Latin American and Caribbean Health Science Information database and the Global Resource of EczemA Trials database in addition to clinical trial protocol registries. Title, abstract and full paper screening as well as data extraction will be conducted in duplicate by independent researchers. Primary outcomes include efficacy with regards to clinician-reported signs and patient-reported symptoms and safety with regards to withdrawal from treatment due to adverse events and the occurrence of serious adverse events. Secondary outcomes will include change in quality of life and itch severity. Where possible and appropriate, network meta-analysis will be performed for each outcome using a random-effects model within a Bayesian framework. If appropriate, the review will be transitioned to a living review with continuous updating of the analysis.Ethics and disseminationDissemination in a peer-reviewed scientific journal is planned.PROSPERO registration numberCRD42018088112; Pre-results.

Objective to present the knowledge produced about sleep and Acute Coronary Syndrome in order to assist in the elaboration of the operational and conceptual definitions of the defining characteristics of the nursing diagnosis Disturbed Sleep Pattern (00198). Method integrative review in the following databases: COCHRANE; SCOPUS; MEDLINE (Medical Literature Analysis and Retrieval System Online) via Pubmed; LILACS (Latin American and Caribbean Health Science Literature Database); CINAHL (Cumulative Index to Nursing and Allied Health Literature) and EMBASE (The Excerpta Medical Database). At the end of the search, 2827 studies were found, 43 were selected for reading, and 10 were included in the review. The gray literature was also included. Results important findings related to clinical evidence and contributing factors of sleep were found in the review. However, in order to build definitions of the defining characteristics, it was necessary to use gray literature, such as a Portuguese dictionary and two textbooks about sleep. Conclusion the definitions will help nurses in their practice in the collection of information, in the determination of the nursing diagnosis studied here, and in directing care measures with respect to quantity and quality of sleep of Acute Coronary Syndrome inpatients. They will also assist in the next steps of the validation of this diagnosis to the referred population.

Background and Study Aim. The aim of this study was to investigate the effect of 6 weeks theraband training on respiratory parameters, upper extremity muscle strength and 50-100m swimming performance in swimming athletes. Material and Methods. Totally 12 male swimmers participated voluntarily and were divided into two groups as control group (n=6) and experimental group (n=6). Control group did only swimming training, experimental group did theraband exercises in addition to swimming exercises. Respiratory parameters, upper extremity anaerobic performance, shoulder extension/flexion strength and swimming performance were measured. Mann Whitney-U Test was used to determine the differences between two groups. Wilcoxon Test was used to determine intra-group differences. Results. There was no statistically significant difference between the pre and post-test values of respiratory parameters, anaerobic performance values and swimming measurements of the experimental groups (p>0.05). There was a statistically significant difference between shoulder extension and flexion values (p<0.05). As for the statistical results between the pre and post-test values of the control group, no significant difference was found in any of the variables (p>0.05). There was a statistically significant difference between the post-test values ​​of the experimental and control groups shoulder extension and flexion values (p<0.05). There was no statistically significant difference between respiratory function parameters, anaerobic performance values and 50-100m swimming degrees (p>0.05). Conclusions. As a result of the findings, it can be said that theraband training which is done as a land work with swimming training leads to positive effects in the upper extremity muscle strength and swimming performance development of youth swimmers.

Objectives. To assess the effects of WBV exercise on patients with KOA.Methods. Eight databases including Pubmed, EMBASE, Cochrane Library, CINAHL, Web of Science, the Physiotherapy Evidence Database, CNKI, and Wanfang were searched up to November 2014. Randomized controlled trials (RCTs) of WBV for KOA were eligible. The outcomes were pain intensity, functional performances, self-reported status, adverse events, and muscle strength. A meta-analysis was conducted.Results. Five trials with 168 participants provided data for the meta-analysis. No significant difference was shown in pain intensity and self-reported status between WBV and other forms of exercise. Improvement in functional performance (evaluated by BBS; WMD, 2.96; 95% CI, 1.29 to 4.62;P=0.0005) was greater in WBV group, but the other parameters of functional performance (including 6MWT and TGUG) revealed no statistically significant difference. Adverse events were only reported in one trial and no significant difference was discovered in muscle strength. The overall quality of evidence was very low.Conclusion.Currently there is only limited evidence that suggested that WBV is effective in the treatment of KOA. Large, well-designed RCTs with better designs are needed.Erratum to “Whole-Body Vibration Exercise for Knee Osteoarthritis: A Systematic Review and Meta-Analysis”

This paper describes a study comparing articles from Latin America and other regions, to assess the quality of both methodology and results presentation. These articles were included in a systematic review about the prevalence of postpartum depression. The study is of the documentary research type with critical analysis of the literature. Two independent reviewers performed the critical analysis of the studies. The quality of the articles was measured according to the Loney Scale. Statistical analysis was applied and the hypotheses were tested through the usage of non-parametric tests. Thirty-four Latin American studies were identified, evaluated, and compared to a random sample of thirty-four articles from other regions. The quality of the methodology and results of the two groups of articles did not show a significant difference. In both cases, quality was found to be low. Scientific articles are evidences that can support decision-making both in the clinical practice and in public policymaking. For authors to generate scientific articles of quality that are reliable evidence is necessary to build the capability of researchers in developing rigorous methodologies to generate consistent results.

Revisión Sistemática

  El zumo de remolacha (ZR) es una fuente nutricional rica en nitrato (NO3-) que, una vez ingerido, es reducido a óxido nítrico (ON). El ON posee efectos hipotensores, anti-inflamatorios y provoca mejoras en la eficiencia mitocondrial y en la regulación de la contractilidad muscular. Distintas investigaciones han comprobado que la suplementación con ZR presenta un efecto ergogénico en modalidades de resistencia cardiorrespiratoria y esfuerzos explosivos e intermitentes de alta intensidad. Sin embargo, dado que ninguna revisión ha valorado el efecto de la suplementación con ZR sobre la producción de fuerza muscular, el objetivo de la presente revisión sistemática es analizar el efecto de la suplementación con ZR sobre el rendimiento en la fuerza muscular. La búsqueda mediante palabras clave y conectores booleanos se realizó en las bases de datos Dialnet, Directory of Open Access Journals, Medline, Pubmed, Scielo, Scopus y SPORTDiscus. La estrategia de búsqueda empleada fue la siguiente: (nitrate OR beet*) AND (concepto 2) (supplement* OR nutr* OR diet*) AND (concepto 3) (strength OR "resistance exercise" OR "resistance training" OR "muscular power"). Tras la aplicación de los criterios de inclusión, un total de 14 artículos fueron seleccionados para la revisión. En la revisión se ha comprobado como la suplementación con ZR puede tener un efecto ergogénico sobre la producción de fuerza muscular bajo estimulación eléctrica, así como sobre la producción de potencia sobre contracciones isocinéticas únicamente a altas velocidades angulares, siendo el mecanismo explicativo una potenciación de la capacidad contráctil específicamente en las fibras musculares tipo II. Abstract. Beet juice (BJ) is a nutritional source rich in nitrate (NO3-) which, after ingestion, is reduced to nitric oxide (NO). NO has effects such as reduction in arterial pressure, anti-inflammatory effects, enhancement of mitochondrial efficiency, and regulation of muscle contractility. Different studies have reported that BJ supplementation has an ergogenic effect in modalities of cardiorespiratory endurance and explosive and intermittent high intensity efforts. Nevertheless, no review has assessed the effect of BJ supplementation on muscle strength production. Thus, the objective of this systematic review is to analyse the effect of BJ supplementation on muscle strength performance. The search using keywords and Boolean connectors was carried out in the databases Dialnet, Directory of Open Access Journals, Medline, Pubmed, Scielo, Scopus, and SPORTDiscus. The search strategy used was the following: (nitrate OR beet *) AND (concept 2) (supplement * OR nutr * OR diet *) AND (concept 3) (strength OR "resistance exercise" OR "resistance training" OR "muscular power "). After the application of the inclusion criteria, a total of 14 articles were selected for review. The review has shown how BJ supplementation can have an ergogenic effect on the production of muscle strength under electrical stimulation, as well as on the production of power over isokinetic contractions only at high angular speeds, the explanatory mechanism being a potentiation of the contractile capacity specifically in type II muscle fibers.

Background and Aims: Recipient demographics affect outcomes after kidney transplantation. The aim of this study was to assess, for kidneys retrieved from living donors, the effect of recipient sex, ethnicity, and body mass index (BMI) on delayed graft function (DGF) and one-year graft function, incidence of acute rejection (AR), and recipient and graft survivals. Methods: A systematic review and meta-analysis was performed. EMBASE and MEDLINE databases were searched using algorithms through Ovid. Web of Science collection, BIOSIS, CABI, Korean Journal database, Russian Science Citation Index, and SciELO were searched through Web of Science. Cochrane database was also searched. Risk of bias was assessed using the NHBLI tools. Data analysis was performed using Revman 5.4. Mean difference (MD) and risk ratio (RR) were used in analysis. Results: A total of 5129 studies were identified; 24 studies met the inclusion criteria and were analysed. Female recipients were found to have a significantly lower serum creatinine 1-year-post renal transplantation (MD: −0.24 mg/dL 95%CI: −0.18 to −0.29 p < 0.01) compared to male recipients. No significant difference in survival between male and female recipients nor between Caucasians and Africans was observed (p = 0.08). However, Caucasian recipients had a higher 1-year graft survival compared to African recipients (95% CI 0.52−0.98) with also a lower incidence of DGF (RR = 0.63 p < 0.01) and AR (RR = 0.55 p < 0.01). Recipient obesity (BMI > 30) was found to have no effect on 1-year recipient (p = 0.28) and graft survival (p = 0.93) compared to non-obese recipients although non-obese recipients had a lower rate of DGF (RR = 0.65 p < 0.01) and AR (RR = 0.81 p < 0.01) compared to obese recipients. Conclusions: Gender mismatch between male recipients and female donors has negative impact on graft survival. African ethnicity and obesity do not to influence recipient and graft survival but negatively affect DGF and AR rates.
