BACKGROUND: The acute and chronic effects of stretching preceding exercises on strength, power and muscular endurance are still not entirely clear in the literature. OBJECTIVE: To verify the acute and chronic effects of the main types of stretching (static, dynamic, PNF, and ballistic) on muscle strength, power, and endurance. METHODS: A systematic literature search was performed in: PubMed, Web of Science, LILACS, Scopus, Science Direct, and CENTRAL. The methodological quality was assessed using the PEDro scale. Meta-analysis were performed using the standardized mean difference (SMD). RESULTS: 43 studies were included in the systematic review and 30 in the meta-analysis calculations. Only two studies showed high methodological quality. In general, static stretching had an impact on the potentiated the gain in muscle strength of the lower limbs in the long term (0.60 [0.20–1.00]). The acute (ES = 0.38 [0.05–0.70]) and long-term (ES = 1.04 [0.21–1.88]) dynamic stretching was able to potentiate the gain of muscle power in the lower limbs, while the acute PNF had an impact on the worsening of the muscular endurance (ES = 1.68 [0.83–2.53]). CONCLUSIONS: When the training objective is linked to acute effects, dynamic stretching should be prioritized before the main activity. For long-term effects, static and dynamic stretching have been shown to potentiate muscle strength and power gain, respectively, and are recommended in these cases. [ABSTRACT FROM AUTHOR]

Purpose: To estimate the prevalence and severity of impairments in functional status, fatigue, and health-related quality of life (HRQoL) among critical COVID-19 survivors one-year after hospital discharge. Methods: A systematic review was conducted following PRISMA statement and registered in PROSPERO (CRD42021258356), with searches in eight databases. Observational studies were selected. The prevalence meta-analysis of abnormalities was performed using random-effects models. Risk of bias was evaluated using the National Heart, Lung, and Blood Institute tool. Results: Twenty studies were included, with data collected between 12 and 13.5 months after hospital discharge and a total of 1828 participants. Of these, 71% were men, and 77.7% were intubated in the intensive care unit (ICU). Impairments and sequelae were identified in varying prevalence and degrees, with greater impact on functional capacity and physical components of fatigue and HRQoL. The prevalence of abnormalities of 32.3% [95% CI 23.9; 41.9] found in the meta-analysis is substantially high. Most studies were classified as having fair and poor quality. Conclusion: Critical COVID-19 survivors experience impairments in functional status, fatigue, and HRQoL to varying degrees one-year after hospital discharge, particularly among patients who stayed in the ICU and on MV for a prolonged period. IMPLICATIONS FOR REHABILITATION: Critical COVID-19 survivors exhibit persistent impairments one-year post-discharge. Functional status, fatigue, and health-related quality of life are impaired to varying degrees in approximately one-third of patients. Long-term follow-up care for critical COVID-19 survivors should be prioritized. [ABSTRACT FROM AUTHOR]

Objectives: This manuscript presents a systematic review of the impact of the COVID-19 pandemic on head and neck cancer (HNC) patients. A meta-analysis was made to compare the number of treated/operated HNC patients in the pre-COVID-19 era versus the COVID-19 era. This investigation was based on previous reports showing a delay in the diagnosis and treatment of new cases of cancer during the pandemic. Worsening in cancer prognosis would be expected as a result of the delayed treatments. Method and materials: An electronic search was conducted using the PubMed/MEDLINE, Embase, Web of Science, Scopus, and The Cochrane Library databases. Relevant articles were selected based on specific inclusion criteria. Results: A total of 8,942 HNC patients were included. A higher prevalence in male (1,873) in comparison to female (1,695) was observed considering 3,568 patients. Regarding staging, the majority of cases were stage III to IV. The treatment type more frequently described was surgery. Positive diagnosis for COVID-19 in the pre-oncologic treatment was reported for 242 patients, and for post-oncologic treatment in 119 patients. Mortality by COVID-19 was reported for 27 HNC patients. The meta- analysis revealed a significantly smaller number of surgeries/ oncologic treatments of HNC patients performed (2,666) in the COVID-19 era when compared to the pre-COVID-19 era (3,163) (Mantel--Haenszel odds ratio = 0.81, 95% CI = 0.65 to 1.00, P = .05). Conclusion: The impact of the COVID-19 pandemic on HNC patients occurred mainly in the number of surgeries/ oncologic treatments, showing a significantly smaller number of surgeries/oncologic treatments performed in the COVID-19 era rather than the pre-COVID-19 era.

Aim: Sarcopenic obesity (SO) is characterized by the coexistence of the loss of muscle mass and function with excess adipose tissue. Its prevalence has increased concomitantly with population aging, becoming one of the most significant challenges for public health, threatening the quality of life and the physical and mental health of the elderly population. Methods: This study estimated the prevalence and factors associated with SO among adults and the elderly in Brazil's macro‐regions, utilizing MEDLINE, Embase, Web of Science, and the Virtual Health Library databases. Primary outcomes included SO prevalence overall and by subgroups, with secondary outcomes identifying associated factors. Results: A systematic review of 33 studies with 10 266 participants up to July 2023 showed a 17% prevalence of SO (95% confidence interval: 13–21%), using a random effects meta‐analysis. The Central‐West region had the highest occurrence (27%). Dual‐energy X‐ray absorptiometry (26%) and bioimpedance (6%) were the top diagnostic methods. Protective factors were chronic kidney disease and healthy lifestyles; risk factors included socioeconomic status, functionality, lifestyle, biochemical parameters, and comorbidities such as osteoarthritis and apnea. Conclusions: The prevalence of SO in Brazil is significant, emerging as a critical public health problem. It is essential to direct attention to changes in prevalence rates in the coming years, given the rising obesity trends and the absolute increase in the elderly population.

Introduction: New therapies for resistant hypertension (RH), including renal denervation (RDN), have been studied. Aim: Access the safety and effectiveness of radiofrequency-based RDN vs pharmacological treatment for RH. Methods: A thorough literature search was conducted across PubMed, EMBASE, and the Cochrane databases, focusing on studies that compared the effects of radiofrequency-based RDN versus pharmacological treatment for RH. Treatment effects for binary and continuous endpoints were pooled and used, respectively, odds-ratio (OR) and mean differences (MD) with 95% confidence intervals (CI) to analyze continuous outcomes. Results: In the 10 included studies, involving 1.182 patients, 682 received radiofrequency-based RDN. The follow-up period ranged from 6 to 84 months. Analysis revealed that the RDN group had a significant reduction in office systolic blood pressure (BP) (MD − 9.5 mmHg; 95% CI − 16.81 to − 2.29; P = 0.01), office diastolic BP (MD − 5.1 mmHg; 95% CI − 8.42 to − 2.80; P < 0.001), 24 h systolic BP (MD − 4.8 mmHg; 95% CI − 7.26 to − 2.42; P < 0.001). For 24 h diastolic BP RDN did not have a significant reduction (MD − 2.3 mmHg; 95% CI − 4.19 to − 0.52; P = 0.012). The heterogeneity between the studies was high, visible in the funnel and Baujat plots. The OR was non-significant for non-serious adverse events, but also clinically significant for hypertensive crises and strokes for the RDN group. Conclusions: While the pharmacological regimen of 3 or more anti-hypertensive, including a diuretic, still be the first-line option for RH treatment, our results support that radiofrequency-based RDN is superior in reducing global BP and is safe.

(1) Background: Body dysmorphic disorder (BDD) presents significant challenges in aesthetic and reconstructive plastic surgery, impacting patient outcomes and well-being. Understanding its prevalence and associated factors is crucial for effective patient care. (2) Methods: A systematic review of national and international databases on body dysmorphic disorder, plastic surgery, cosmetic surgery, reconstructive surgery, and prevalence yielded 999 studies between 1878 and April 2024. Inclusion criteria focused on studies reporting prevalence while excluding those with small sample sizes (<20 participants), unclear diagnostic criteria for BDD, and non-English accessibility. (3) Results: A meta-analysis using a random effects model was conducted on 65 studies involving 17,107 patients to estimate the prevalence of BDD. The overall estimated prevalence of BDD was 18.6%; 10,776 (62.9%) were females, with a mean age of 35.5 ± 11.7 years. Subgroup meta-analysis found significant variability in effect sizes across countries and types of specialty, of which Brazil showed the highest proportion and dermatology exhibited the smallest. Meta-regression analysis found no significant relationship between the year of publication and prevalence rates. (4) Conclusions: Our findings update the current literature on BDD prevalence in aesthetic and reconstructive plastic surgery. We emphasize the importance of proactive screening and multidisciplinary care approaches to address the complex challenges posed by patients with BDD. Further research is needed to explore evolving trends in BDD prevalence and factors influencing its expression across different cultural contexts. [ABSTRACT FROM AUTHOR]

The aim was to evaluate the effect of probiotics‐containing beverages on dental caries development by a systematic review and meta‐analysis (PROSPERO CRD42021258010). PubMed, Embase, and Web of Science databases were assessed (up to October 2023) for randomized placebo‐controlled trials that evaluated the consumption of probiotics‐containing beverages having dental caries as endpoint. Risk of bias assessment (Cochrane Handbook) was performed for all studies. Risk ratio (RR), standardized mean difference (SMD) and 95% confidence interval (CI), were calculated for caries prevalence and caries increment, respectively. Meta‐analysis was performed. Qualitative analysis of more than 2000 individuals aged from 1 to 84 years (9 studies) showed inconsistent effects of these probiotics‐containing beverages. Synthesis of more than 1000 children and adolescents did not demonstrate a statistically significant difference in the proportion of individuals with cavitated lesions (RR 0.60 [95 % CI 0.34 to 1.08]; n = 2), but a significantly smaller increment of both cavitated and non‐cavitated carious lesions (SMD −0.23 [95 % CI −0.39 to −0.08]; n = 4) was related to the consumption of probiotics‐containing beverages. Certainty of evidence for caries prevalence and caries increment were moderate and low, respectively. Current evidence is not substantial to strengthen the impact of these beverages on caries development. [ABSTRACT FROM AUTHOR]

BACKGROUND: The potential health benefits of exposure to vegetation, or greenness, are well documented, but there are few nationwide studies in Brazil, a country facing challenges related to land-use planning, deforestation, and environmental health risks. OBJECTIVES: In this study, we investigated the association between greenness and hospitalizations for cardiorespiratory diseases in Brazil. METHODS: We accessed hospital admissions data from 967,771 postal codes (a total of 26,724,624 admissions) covering Brazil for the period between 2008 and 2018. We used Normalized Difference Vegetation Index (NDVI) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) to measure greenness at the postal-code level. First, we applied a quasi-Poisson regression model to estimate the association between greenness and hospitalizations for circulatory and respiratory diseases, adjusted for air pollution, weather variables, and area-level socioeconomic status. We stratified the analyzes by sex, age group, health outcome, and Brazilian regions. In the second stage, we performed a meta-analysis to estimate pooled effects across the Brazilian regions. RESULTS: The national meta-analysis for the whole population, incorporating both urban and nonurban areas, showed that higher levels of greenness were associated with a lower risk of hospitalizations for circulatory diseases. An interquartile range (IQR=0.18) increase in average NDVI was associated with a 17% (95% confidence interval: 8%, 27%) lower risk of cardiovascular admissions. In contrast, there was no association found between greenness and respiratory admissions. When specifically examining urban areas, the results remained consistent with the overall findings. However, the analyses of nonurban areas revealed divergent results, suggesting that higher levels of greenness in rural regions are associated with a lower risk of hospital admissions for both circulatory and respiratory diseases. DISCUSSION: The findings emphasize the importance of prioritizing the preservation and creation of green spaces in urban areas as a means of promoting cardiovascular health in Brazil.

The impact of climate change on rice yield varies among different rice varieties. Designing effective agronomic adaptation strategies is crucial for global rice provision. However, considerable uncertainty remains as to which approaches/strategies should be used in different regions. To this end, we conducted a meta-analysis aimed at quantifying firstly the marginal effects of climate change (i.e., temperature, precipitation, and CO2) and four adaptation strategies (i.e., changing varieties, adjusting fertilization, adjusting irrigation, and altering planting dates) on rice yield in Indica, Japonica, and Hybrid rice. We further assessed climate risks to rice yield and identified optimum adaptation strategies under three shared socio-economic pathway (SSP) scenarios. The results of the meta-analysis showed that temperature has the greatest negative marginal effect of −3.11% on rice yield, with changing varieties being the most effective strategy (15.93%) to counter this effect, followed by increased irrigation (0.24%). Projected climate scenarios predict a 2.11% global average rice yield decrease in the 2040s under SSP5-8.5. Japonica rice yields are significantly more pessimistic than Indica and Hybrid rice. To offset this, 86.48% of the rice planting area would need to change varieties; increase fertilization and irrigation by 51.22% and 8.54%, respectively; or plant in advance by 13 days. Major rice-producing countries such as India, China, and Brazil will need adaptation strategies with higher urgency and scale than the global average. These findings form a basis for a better understanding of climate resilience in different rice varieties and agronomic strategies. Our analysis suggests that it is possible for future rice yield to meet the needs of rice-growing countries while supporting eco-friendly rice production if the appropriate measures are taken. Overall, this study attempts firstly to design effective agronomic adaptation strategies to enhance rice production resilience against climate change and advance understanding of rice varietal adaptation for improved management.

We evaluated the advantages and disadvantages of two phacoemulsification techniques: phaco-chop and divide-and-conquer. Methods: PubMed, Cochrane, Embase, and Web of Science databases were queried for randomized controlled trial (RCT), prospective and retrospective studies that compared the phaco-chop technique over the divide-and-conquer technique and reported the outcomes of (1) Endothelial cell count change (ECC); (2) Ultrasound time (UST); (3) Cumulated dissipated energy (CDE); (4) Surgery time; and (5) Phacoemulsification time (PT). Heterogeneity was examined with I2 statistics. A random-effects model was used for outcomes with high heterogeneity. Results: Nine final studies, (6 prospective RCTs and 3 observational), comprising 837 patients undergoing phacoemulsification. 435 (51.9%) underwent the phaco-chop technique, and 405 (48.1%) underwent divide-and-conquer. Overall, the phaco-chop technique was associated with several advantages: a significant difference in ECC change postoperatively (Mean Difference [MD] − 221.67 Cell/mm2; 95% Confidence Interval [CI] − 401.68 to − 41.66; p < 0.02; I2=73%); a shorter UST (MD − 51.16 sec; 95% CI − 99.4 to − 2.79; p = 0.04; I2=98%); reduced CDE (MD − 8.68 units; 95% CI − 12.76 to − 4.60; p < 0.01; I2=84%); a lower PT (MD − 55.09 sec; 95% CI − 99.29 to − 12.90; p = 0.01; I2=100). There were no significant differences in surgery time (MD − 3.86 min; 95% CI − 9.55 to 1.83; p = 0.18; I2=99%). Conclusion: The phaco-chop technique proved to cause fewer hazards to the corneal endothelium, with less delivered intraocular ultrasound energy when compared to the divide-and-conquer technique.

Background and Objectives: Newborns as a vulnerable population are exposed to congenital and acquired infections during and after birth. There are several reports of the isolation and reporting of infectious agents (IAs) in early life of newborns with respiratory manifestations, and the present comprehensive study provides a snapshot of the current global situation of the prevalence of IAs in newborns with respiratory symptoms. Materials and Methods: A systematic search was conducted in main databases, including PubMed, Scopus, Web of science, and Google scholar. The pooled prevalence of infectious agents (IAs) in newborns was estimated using comprehensive meta-analysis software based on random effects model. Results: Out of 44 inclusive studies (50 datasets) for IAs in newborns, the pooled prevalence was estimated to be 12.2% (95% CI: 6.40-22.0%) and the highest and lowest prevalence of IAs was related to the Brazil (78.2%, 95% CI: 31.0-96.6%), and UK (0.01%, 95% CI 0.01-0.01%) respectively. Conclusion: The high prevalence of IAs in newborns emphasizes considers the necessary measures to prevent respiratory infections. [ABSTRACT FROM AUTHOR]

To investigate the effects of aquatic exercise programs (AEP) in body structure and function, activity, and participation outcomes in individuals with Parkinson's disease (PD) with mild to moderate disability levels. Six databases were searched from inception until November 2022. Randomized clinical trials that used AEP alone, AEP combined and/or compared two types of AEP were included. The quality of evidence was assessed by the GRADE approach and the standardized mean differences (SMD) were calculated the meta-analysis. Twelve studies (n = 380) were included. AEP alone was superior to active control in improving body structure and function outcome: postural balance (low evidence, SMD = 0.47, p = 0.02). No statistically significant differences were found for the other body structure and function outcomes: lower limb muscle strength (p = 0.14) and depressive symptoms (p = 0.79), activity outcomes: mobility (p = 0.32) and participation outcomes: quality of life (p = 0.05). AEP combined showed no statistically significant difference for the outcomes of body structure and function: postural balance (p = 0.11) and activity: mobility (p = 0.21) when compared to active control. AEP showed positive effects on body structure and function outcome (postural balance) in individuals with PD with mild to moderate disability levels while, no significant improvements were noticed for activity and participation outcomes. Our findings indicate that aquatic exercise programs (AEP) lead to significant improvements on body structure and function (i.e., postural balance) in individuals with Parkinson's disease (PD). The AEP evaluated in this study implemented postural balance, gait, single and double training, as well as aerobic exercises, trunk mobility exercises, and Ai Chi. The average duration, frequency, and total time implemented were 50 minutes, three times a week, for seven weeks, respectively. Considering the potential benefits identified in this study, AEP can be recommended as an adjunct treatment strategy for individuals with PD. Additionally, the use of the International Classification of Functionality, Disability and Health on the development of rehabilitation treatment plans is advised. [ABSTRACT FROM AUTHOR]

Background and Objectives: Red blood cell transfusions are frequent in preterm neonates. The proportion of preterm neonates transfused in Brazil remains unknown. We systematically reviewed the literature to estimate the frequency of red blood cell transfusions in preterm neonates in Brazil. Materials and Methods: The LILACS, EMBASE, Cochrane, SciELO, MEDLINE (PubMed), Web of Science, Scopus, BDTD and 27 national university institutional databases were searched for studies that analysed red blood cell transfusion in preterm neonates in Brazil without period restriction. The Preferred Reporting Items in Systematic Reviews and Meta‐Analyses guidelines were followed, and the GRADE methodology was applied. A random‐effects model along with the restricted maximum likelihood method was used, and the Freeman–Tukey transformed proportion was used to estimate effect size. Results: Nine studies, representing 6548 preterm neonates, were included in the qualitative and quantitative analyses. The mean gestational age ranged from 26.0 to 31.6 weeks. Most of the studies were from the Southeast region. The pooled estimated frequency of red blood cell transfusions was 58.0% (95% confidence interval = 52.0%–64.0%, p < 0.001) with low certainty. There was statistically significant heterogeneity among studies (I2 = 92.5%, p < 0.001). Conclusion: In this current meta‐analysis of the evidence available, which included moderate and extremely preterm neonates, the observed frequency of red blood cell transfusions in preterm neonates in Brazil was 58.0% and this estimate can help health programming. Some Brazilian regions were not included in this study, and further research is needed to provide a more representative overview of Brazil. [ABSTRACT FROM AUTHOR]

To identify the prevalence of geographic tongue in patients >18 years. A systematic literature review was performed in search of population‐based observational studies. Searches were performed using five main databases: Embase, LILACS, PubMed, Scopus and Web of Science; and three gray literature sources: Google Scholar, ProQuest, and OpenGrey. In addition, a manual search in the reference list and consultation with experts on the topic studied were performed. Methodological quality was assessed using the Joanna Briggs Institute's checklist for prevalence studies. Ratio meta‐analyses were performed using JAMOVI. Initially, 3046 studies were identified. After a two‐phase selection, 11 studies were included for quantitative synthesis. Two studies were classified as of low methodological quality, five studies as of moderate quality, and four as of high quality. Two types of prevalence were analyzed: by period and point. Three studies were included in the period prevalence meta‐analysis, and the prevalence was 3% (Confidence interval [CI]: 0.4%–5.5%, n = 9813). Eight studies were included in the point‐prevalence meta‐analysis, and the prevalence was 3% (CI: −0.2% to 5.5%, n = 10,967). Although there are phases of exacerbation and remission in geographic tongue, prevalence and period prevalence were similar. Approximately one in 30 adults has a geographic tongue.

Background: This systematic review and meta-analysis sought to investigate the patterns of use of native wild food plants of Brazil (native and non-cultivated). Methods: We searched ethnobiological works with food plants in Web of Science, Scielo, Scopus and PubMed using different sets of keywords. Initially, the studies were evaluated based on inclusion criteria (systematic data collection instruments, such as interviews; specification of methods for data collection; and the presence of a species list). The methodological quality of each study was evaluated to define the risk of bias. A total of 20 articles met all criteria and were included in the review. Results: The results showed that there was a predominance of consumption of fruits, followed by leaves and seeds, which together represented 85.8% of the total parts. As for the meta-analysis, there was a predominance of use of plant parts classified as reproductive, non-persistent, non-destructive and parts of woody plants. There was no interference from the type of ecosystem (seasonally dry x moist). The results did not support the seasonality hypothesis. Conclusions: The concentration of studies in the Northeast, Southeast and South regions of Brazil and in the Atlantic Forest and Caatinga biomes points to the need for a greater effort in terms of quantitative ethnobotanical research in other regions and biomes. The predominance of fruits and plant parts classified as reproductive, non-persistent and non-destructive points to the high potential for implementation of sustainable management strategies aimed at these plants in the country.

The purpose of the current study is to describe the prevalence of Pseudomonas aeruginosa (PA)-producing MβL among Brazilian isolates and the frequency of blaSPM-1 in MβL-PA-producing isolates. From January 2009 to August 2023, we carried out an investigation on this subject in the internet databases SciELO, PubMed, Science Direct, and LILACS. A total of 20 papers that met the eligibility requirements were chosen by comprehensive meta-analysis software v2.2 for data retrieval and analysis by one meta-analysis using a fixed-effects model for the two investigations. The prevalence of MβL-producing P. aeruginosa was 35.8% or 0.358 (95% CI = 0.324–0.393). The studies' differences were significantly different from one another (x2 = 243.15; p < 0.001; I2 = 92.18%), so they were divided into subgroups based on Brazilian regions. There was indication of asymmetry in the meta-analyses' publishing bias funnel plot; so, a meta-regression was conducted by the study's publication year. According to the findings of Begg's test, no discernible publishing bias was found. blaSPM-1 prevalence was estimated at 66.9% or 0.669 in MβL-PA isolates (95% CI = 0.593–0.738). The analysis of this one showed an average heterogeneity (x2 = 90.93; p < 0.001; I2 = 80.20%). According to the results of Begg's test and a funnel plot, no discernible publishing bias was found. The research showed that MβL-P. aeruginosa and SPM-1 isolates were relatively common among individuals in Brazil. P. aeruginosa and other opportunistic bacteria are spreading quickly and causing severe infections, so efforts are needed to pinpoint risk factors, reservoirs, transmission pathways, and the origin of infection.

Summary: This current work presents a meta‐analysis to determine coffee bean specifications [types (Arabica and Robusta), roasting degree (light, medium and dark), roasting condition (time and temperature) and geographical origins by countries (Brazil, India and Thailand)] with the highest antioxidant activity. A total of 12 articles and 189 data points were employed for meta‐analysis of subgroups. The results showed that the Arabica coffee bean was reported to have the highest antioxidant activity as assessed by ferric reducing antioxidant power (FRAP) and 2,2‐azinobis‐3 ethyl benzothiazoline‐6‐sulfonic acid (ABTS). In addition, the light roasting degree of coffee beans produced the highest antioxidant activity as assessed by FRAP and 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH). Roasting degree is a better parameter to obtain coffee beans with higher antioxidant activity compared to roasting conditions. Coffee from Brazil and India was found to have higher antioxidant activity compared with coffee from Thailand. This study concludes that Arabica coffee beans from Brazil or India with a light roasting degree are expected to have high antioxidant activity. [ABSTRACT FROM AUTHOR]

Vitamin A is an essential micronutrient, especially during pregnancy. We aimed to assess the prevalence of vitamin A deficiency in Brazilian women of childbearing age. We conducted a systematic review with meta-analysis of studies that assessed vitamin A deficiency in women of childbearing age following the registered protocol (CRD42020171856). Independent peer researchers selected the studies retrieved from MEDLINE, Embase, Scopus and other sources. Data from the eligible studies were extracted in pairs and assessed for methodological quality. The prevalence of vitamin A deficiency (< 0·70 µmol/l or <0·20 µg/dl) and 95 % CI was combined by meta-analysis, and heterogeneity was estimated by I 2. Out of 3610 screened records, thirty-two studies were included, which assessed 12 577 women from 1965 to 2017, mostly in maternity hospitals. Main limitations of the studies were in sample frame (30/32) and sampling method (29/32). Deficiency occurred in 13 % (95 % CI 9·4, 17·2 %; I² = 97 %) of all women and was higher in pregnant women (16·1 %; 95 % CI 5·6, 30·6 %; I² = 98 %) than non-pregnant women (12·3 %; 95 % CI 8·4, 16·8 %; I² = 96 %). The prevalence increased according to the decade, from 9·5 % (95 % CI 1·9–21·6 %; I² = 98 %) up to 1990, 10·8 % (95 % CI 7·9, 14·2 %; I² = 86 %) in the 2000s and 17·8 % (95 % CI 8·7, 29·0 %; I² = 98 %) in the 2010s. Over 10 % of Brazilian women in childbearing age were deficient in vitamin A. Higher prevalence was observed in pregnant women, and deficiency seemed to be increasing over the decades. Low representativeness of the studies, mainly based on convenience sampling that included pregnant, postpartum, lactating and non-pregnant women, as well as high heterogeneity, limits the findings.

Objective of this study was to conduct a systematic review and meta-analysis to identify the adverse effects of acute PM2.5 exposure on lung function in children. Design: Systematic review and meta-analysis. Setting, participants and measures: Eligible studies analyzing PM2.5 level and lung function in children were screened out. Effect estimates of PM2.5 measurements were quantified using random effect models. Heterogeneity was investigated with Q-test and I2 statistics. We also conducted meta-regression and sensitivity analysis to explore the sources of heterogeneity, such as different countries and asthmatic status. Subgroup analyses were conducted to determine the effects of acute PM2.5 exposure on children of different asthmatic status and in different countries. Results: A total of 11 studies with 4314 participants from Brazil, China and Japan were included finally. A 10 μg/m3 increase of PM2.5 was associated with a 1.74L/min (95% CI: − 2.68, − 0.90) decrease in peak expiratory flow (PEF). Since the asthmatic status and country could partly explain the heterogeneity, we conducted the subgroup analysis. Children with severe asthma were more susceptible to PM2.5 exposure (− 3.11 L/min per 10 μg/m3 increase, 95% CI − 4.54, − 1.67) than healthy children (− 1.61 L/min per 10 μg/m3 increase, 95% CI − 2.34, − 0.91). In the children of China, PEF decreased by 1.54 L/min (95% CI − 2.33, − 0.75) with a 10 μg/m3 increase in PM2.5 exposure. In the children of Japan, PEF decreased by 2.65 L/min (95% CI − 3.82, − 1.48) with a 10 μg/m3 increase of PM2.5 exposure. In contrast, no statistic association was found between every 10 μg/m3 increase of PM2.5 and lung function in children of Brazil (− 0.38 L/min, 95% CI − 0.91, 0.15). Conclusion: Our results demonstrated that the acute PM2.5 exposure exerted adverse impacts on children's lung function, and children with severe asthma were more susceptible to the increase of PM2.5 exposure. The impacts of acute PM2.5 exposure varied across different countries. [ABSTRACT FROM AUTHOR]

Objectives: Since 2010, genome‐wide data from hundreds of ancient Native Americans have contributed to the understanding of Americas' prehistory. However, these samples have never been studied as a single dataset, and distinct relationships among themselves and with present‐day populations may have never come to light. Here, we reassess genomic diversity and population structure of 223 ancient Native Americans published between 2010 and 2019. Materials and Methods: The genomic data from ancient Americas was merged with a worldwide reference panel of 278 present‐day genomes from the Simons Genome Diversity Project and then analyzed through ADMIXTURE, D‐statistics, PCA, t‐SNE, and UMAP. Results: We find largely similar population structures in ancient and present‐day Americas. However, the population structure of contemporary Native Americans, traced here to at least 10,000 years before present, is noticeably less diverse than their ancient counterparts, a possible outcome of the European contact. Additionally, in the past there were greater levels of population structure in North than in South America, except for ancient Brazil, which harbors comparatively high degrees of structure. Moreover, we find a component of genetic ancestry in the ancient dataset that is closely related to that of present‐day Oceanic populations but does not correspond to the previously reported Australasian signal. Lastly, we report an expansion of the Ancient Beringian ancestry, previously reported for only one sample. Discussion: Overall, our findings support a complex scenario for the settlement of the Americas, accommodating the occurrence of founder effects and the emergence of ancestral mixing events at the regional level.

Violence against women is a major problem in Brazil, but data on its prevalence are scarce. We aimed to estimate the prevalence of physical violence against women in Brazil. We conducted a systematic review and meta-analysis of the prevalence of physical violence against women. Population-based researches that assessed physical violence in Brazilian women were searched on MEDLINE, Embase, Scopus, and VHL/BIREME. The last search update was carried out in March 2020. Two researchers selected the studies, extracted the data, and assessed the quality of the eligible studies. Summary of prevalence and 95% confidence interval (CI) was calculated using Freeman–Tukey double arccosine transformation, weighted by the official local population size. Heterogeneity was estimated by I 2 and investigated by meta-regression analyses. Of 3,408 reports, 13 studies carried out from 1999 to 2016 (n = 25,781 women) were included. Most studies had limitations on sample size (5/13) and response rate (7/13). The prevalence of physical violence was 22.4% in lifetime (95% CI [21.6, 23.2%]; I 2 = 99.0%), and 11.5% in previous year (95% CI [11.1, 11.9%]; I 2 = 99.5%). Assuring privacy during interview significantly increased the prevalence (p =.028; residual I 2 = 80.0%). Higher prevalence was also observed in studies with adequate sample source, validated questionnaire, and privacy (in both recall periods), potentially due to lower risk of nonresponse bias. Over two in 10 Brazilian women suffered physical violence during their lives, and over one tenth, in the previous year. Measurement of outcome affected the prevalence; privacy should be assured for the interviewee for future reliable estimates in the country. [ABSTRACT FROM AUTHOR]

Biochar has been intensively researched worldwide. In Brazil, there is a variety of feedstock production that can be turned into soil amendments of high performance through biochar conversion, especially solid wastes. However, advances in biochar research in Brazil have not been systematically evaluated to indicate possible gaps and suggest future research for eco‐friendly applications. Thus, in this work we evaluated biochar properties and effects on air, water, and soil quality based on data gathered from researches performed in Brazil. Biochar has been mainly evaluated as soil conditioner (37%), material characterization (17%), water treatment (12%), and greenhouse gases emissions (9%). Based on the data synthesis of 68 feedstocks used for biochar production, we observed that the pyrolysis temperature profoundly affects biochar properties. Meta‐analysis indicated benefits of biochar addition to soils for chemical, physical, microbiological and biochemical attributes that have resulted in increases in root growth (+30%), and plant shoots (+45%). Pyrolysis temperature and feedstock are key choices to design biochar properties aiming to retain dyes, aromatic hydrocarbon, pesticides, and metals in water and wastewater treatment. It was also observed an increase in CO2 and a decrease in N2O emissions after biochar application to soils in short‐term experiments. Although there is a growing interest in the development of electrochemical sensors and biochar‐based fertilizers, technological applications of biochar are still incipient in Brazil. Future research should prioritize long‐term and mechanistically evaluations of biochar under field conditions and the development of eco‐friendly technological applications. [ABSTRACT FROM AUTHOR]

Ilheus fever is a mosquito-borne, poorly known tropical disease. We aimed to report the pooled rate of exposure to the Ilheus virus (ILHV) and clinical outcomes of infection to determine the epidemiological patterns of ILHV. We conducted a meta-analysis of 37 studies (n = 17,722 individuals) from Latin America. The common clinical characteristics of ILHV infection were fever (82.3%), headache (52.9%), and myalgia (52.9%). Encephalitis complicated the course of the infection in 29.4% cases. Monotypic serological reactions detected a pooled rate of exposure of 2% to ILHV (95% CI: 1–2). Studies were mainly conducted in Brazil, with a pooled proportion of ILHV positivity of 8% (95% CI: 3–14). Males (12%) had higher rates of seropositivity than females (7%) and had high chances of ILHV infection (OR: 1.7, 95% CI: 1.2–2.5). Seropositivity increased with age, from 2% (95% CI: 2–3) among people aged 0–14 years to 8% (95% CI: 6–10) among people aged 15–64 years. Our analysis indicated a low and relatively constant burden of ILHV in Latin America. More research is needed to evaluate and innovate serological assays for ILHV to better estimate the burden and dynamics of epidemiological changes in ILHV infection in different regions.

Objective: To determine the frequency of osteonecrosis of the jaw in bisphosphonate users submitted to dental procedures. Methods: This systematic review searched the sources: MEDLINE, EMBASE, Web of Science, Scopus, and Virtual Health Library, with no restriction on language or publication date. Reviewers, in pairs and independently, selected the studies, extracted their data, and assessed the risk of bias. Meta‐analyses were pooled using the DerSimonian and Laird random effects model. Results: A total of 27 studies (5391 participants) were included. The most reported bisphosphonates were zoledronate (n = 17 studies) and alendronate (n = 19) for treating cancers (n = 11) and osteoporosis (n = 16), respectively. Twelve studies were of low methodological quality. The frequency of osteonecrosis was 2.7% (95% CI: 0.9–5.2%) and proved higher for intravenous [6.9% (0.7–17.3%)] than oral [0.2% (0.9–5.2%)] bisphosphonate use. No association between longer treatment duration and greater frequency of osteonecrosis was observed. Conclusions: Higher frequency of osteonecrosis was observed in intravenous bisphosphonate users submitted to dental extraction. Further studies collecting more detailed information on the bisphosphonates used and of greater methodological rigor are warranted to confirm these findings and better inform prescribers, dental surgeons, and other professionals on risks of bisphosphonate use in this patient group.

Introduction: Metabolic syndrome (MetS) predicts cardiovascular disease, and patients with this condition and type 2 diabetes have increased albuminuria, significantly impacting cardiovascular mortality and kidney disease progression. A considerable number of interventions to control MetS exist and are considered efficient, including the use of medication and changes in lifestyle. However, which approaches are effective in controlling albuminuria remains unclear. This systematic review protocol aims to map in the available literature whether lifestyle, medication, and surgical intervention for MetS have an impact on reducing albuminuria in adult patients. Methods: The Joanna Briggs Institute methodology for systematic reviews will be followed. Cochrane Database of Systematic Reviews, Scopus, Embase, and MEDLINE/PubMed databases will be used. For the Gray Literature, the DART-Europe E-theses Portal. There will be no language restriction. Studies written after 2009 will be included due to the consensus and definition of metabolic syndrome. This review will include studies considering pharmacological and nonpharmacological treatments for controlling albuminuria in patients with MetS. Studies where MetS is described in children and adolescents, animals, pregnant women, and patients with type 1 diabetes will be excluded. First, the selection will be based on reading the title and summary of the texts retrieved in the search strategy, followed by reading the relevant texts in full by two reviewers. After the selection of the studies, the extraction of the data, analysis, and synthesis will be conducted according to the JBI methodology. [ABSTRACT FROM AUTHOR]

Tropical studies traditionally describe insect diversity variation throughout the year. The temporally structured responses of insect assemblages to climate seasonality vary across ecosystems due to gradients of resource availability and limiting ecological factors. These idiosyncratic responses might be particularly true across the vast geographical range of the Brazilian territory, including various environments that harbor one of the most diverse ant faunas worldwide. This study addressed the relationship between ant diversity and climatic seasonality, performing a quantitative review of the published data on ant diversity collected in Brazil. We investigated the seasonality effect on ant abundance and richness described in the literature in 47 papers published between 2000 and 2018. These studies were developed mainly in the Atlantic Forest biome and collected ants with pitfall traps on the soil/litter stratum. We initially carried out a vote-counting procedure by comparing the number of significant results describing seasonal differences in the ant assemblage. We found that most papers described a similar pattern of ant abundance, richness, and species composition between seasons. However, when we performed a meta-analysis, we observed a clear pattern of higher ant abundance and richness in the wet/summer season compared with the dry/winter season. Our meta-analysis reveals that the ant diversity decreases in the dry season, strongly in the Cerrado biome. Additionally, we point out differences in the sampling effort across biomes, indicating the need for further investments in studies focused on temporal diversity patterns, including seasonal effects, on the insect assemblage in biomes less investigated so far.

Myrtaceae is one of the most important families in the Neotropics, with 23 genera and 990 species occurring in Brazil. Seasonal environmental changes can cause alterations in the secondary metabolism of plants and, consequently, in the chemical composition, yield and biological activity of essential oils. The aim of the present study was to determine the influence of seasonality on the chemical composition of essential oils from Myrtaceae species through the technique of meta-analysis. The articles were obtained from searches carried out in Journal Databases (Web Of Science, Scorpus and Science Direct) following the PRISMA protocol. The data that composed this study were binary data (presence or absence) of the influence of seasonality on the composition of essential oils of Myrtaceae species. The meta-analysis effect size was derived from the observational comparison of data obtained from the primary articles available in the literature, which was statistically relevant. The conclusion of the meta-analysis was that seasonality significantly influences the chemical composition of essential oils from Myrtaceae species. The heterogeneity test corroborate the results obtained in the meta-analysis. Determination of the influence of seasonality on the chemical composition of essential oils of Myrtaceae species, through the meta-analysis technique according to the PRISMA protocol for a systematic literature review. [Display omitted] • The influence of seasonality on the chemical composition of essential oils from Myrtaceae species was investigated. • The PRISMA protocol methodology was used in the Systematic Literature Review to apply the meta-analysis technique. • Meta-analysis indicated that seasonality significantly influences the chemical composition of the oil of Myrtaceae species.

Background: A previous 2014 meta-analysis reported a positive association between obesity and periodontitis. It was considered necessary to update the recently published papers and to analyse subgroups on important clinical variables that could affect the association between obesity and periodontitis. Therefore, we updated the latest studies and attempted to derive more refined results. Methods: All observational studies were eligible for inclusion. The Newcastle-Ottawa scale was used to qualitatively evaluate the risk of bias. Subgroup analyses were conducted for patients aged 18-34, 35-54, and 55+ years and the countries (European countries, USA, Brazil, Japan, Korea, and other Asian countries). Results: Thirty-seven full-text articles were included. Obesity conferred increased odds of periodontal disease with an odds ratio (1.35, 95% CI: 1.05-1.75). In the subgroup analysis by age, the odds ratio was the highest in the 18-34 years group (2.21, 95% CI: 1.26-3.89). In the subgroup analysis by country, European countries had the highest odds ratio (2.46, 95% CI: 1.11-5.46). Conclusion: Despite the differences in degree, a positive association between obesity and periodontitis was found regardless of country or age. Therefore, medical professionals should try to prevent periodontitis by controlling patient weights, and more studies should be conducted to determine the association between obesity and oral health.

Introduction: Neurosurgery is an intensely competitive field. With the USMLE Step 1 transitioning to a pass/fail system, research has become a crucial component of the neurosurgery residency application process. This emphasis on research is particularly critical for international medical graduates (IMGs), who often face greater challenges compared to their U.S. counterparts. IMGs typically need more publications and higher H-indices to stand out. However, accessing quality research opportunities is significantly more difficult for those from low- and middle-income countries. This mini-review aims to provide a new perspective for IMGs, demonstrating that publishing in prestigious neurosurgical journals is possible even with limited resources., Methods: We searched Scopus and reviewed Brazilian publications from 2014 to 2023 in Neurosurgery and the Journal of Neurosurgery. We extracted the methodological designs of the studies and the graduation status of the first authors., Results: In 2023-2024, four Brazilian medical students published systematic reviews in major neurosurgical journals as first authors, marking a revolutionary change in the Brazilian neurosurgical landscape not seen in the past decade. These achievements illustrate that high-impact publications are attainable without geographical proximity, substantial financial support, or access to extensive institutional databases. Letters to the editor also represented a considerable Brazilian contribution., Conclusion: Literature reviews and letters to the editor are accessible methods for IMGs to engage in impactful research. IMGs can maximize their abilities and significantly contribute to neurosurgery by embracing literature reviews and meta-analyses. These approaches can open doors for those without other avenues to begin their research careers., (© 2024.

Research Summary: This article reports on an updated systematic review and meta‐analysis of the effects of street lighting interventions on crime in public places. Following Campbell Collaboration guidelines, it uses robust criteria for inclusion of studies, comprehensive search strategies to identify eligible studies, a detailed protocol for coding key study characteristics, and rigorous methods for analyzing studies. A total of 21 studies met the inclusion criteria, originating in four countries (United States, United Kingdom, Brazil, and South Korea) and covering almost 50 years (1974–2021). The review finds that street lighting interventions are associated with a significant desirable effect on total crime (14% reduction in treatment areas compared with comparable control areas); desirable effects are greater in studies that measured both night and day crimes than in studies that only measured night crimes; and street lighting is followed by a significant reduction in property crimes, but not in violent crimes. Policy Implications: Compared to past years, it would seem that an even stronger case can be made today for street lighting interventions to be part of crime‐prevention policy. A larger body of high‐quality evaluation research, implemented in a range of high‐crime public places, some evidence of value for money, and a continued desirable impact on crime, especially property crime, all point to the policy relevance of street lighting interventions.

Background: Individuals exhibiting gender nonconforming behaviors experience low self-esteem and a number of other mental health conditions, including elevated suicide risk. Most of the relevant evidence is confined to US studies, however. Adopting a cross-national approach, we examined the pervasiveness of the psychological burden associated with gender nonconformity. Because self-esteem is sensitive to the fulfillment of societal expectations for gender conformity, we reasoned that the relationship between gender conformity and self-esteem ought to decrease as societies become less restrictive in their gender norms. Methods: To test this proposition, we conducted two studies including 18 national samples from 15 countries varying in gender equality. Participants responded to an online survey that included measures of gender conformity and self-esteem (N = 4486). Results: Using multilevel analyses and meta-analytic statistics over the samples of both studies, we found that as gender equality increased, the association between gender conformity and self-esteem decreased. Conclusions: The results suggest that rather than being inherently noxious, gender non-conformity becomes detrimental to self-esteem when it clashes with restrictive gender role norms that are enacted by the macrosocial context. We suggest that previous findings on psychological problems related to gender nonconformity be considered within a broader macrosocial context that may constrain people's freedom to move against gender role norms.

This systematic review aims to give an overview of the diversity of research areas related to human biometeorology in Brazil. The main focus of this paper addresses research trends, represented by published papers with national and international authorship, main contributions and shortcomings, as well as challenges and prospects of research in this area of study. An extensive literature search was conducted in the Scopus, Web of Science, and Science Direct databases so as to identify relevant publication output up to July 2021 related to the research area. The screening resulted in 96 studies chosen for full-text reading. Overall, results indicated a reduced amount of articles on the subject matter published internationally, with noticeable gaps in research in some regions of the country, such as the Amazon region and in the Brazilian Midwest region. Research gaps in relevant areas have been identified with limited output in the climate dimensions of tourism, vector-borne diseases, mortality and morbidity in urban centers. Such gaps should further encourage researchers to engage in research focused on those areas. [ABSTRACT FROM AUTHOR]

Tropical climate-smart agriculture could be a cost-effective and scalable nature-based solution toward achieving net-zero greenhouse gas (GHG) emissions in the coming decades. Nevertheless, the lack of integrated on-farm CO 2 , CH 4 , and N 2 O flux measurements remains a barrier to including these systems in certification programs and the carbon (C) market. This systematic literature review critically examines field-measured GHG emission studies within climate-smart agri-systems in Brazil, aiming to: (i) integrate GHG-measured data, (ii) explore geographical representativeness and connections between organizations and authors, (iii) analyze distributions of studied GHG molecules, climate-smart system types, and productive components, (iv) conduct a meta-analysis on the adoption of climate-smart agriculture, and (v) identify methodological and scope gaps, providing insights for future research directions. The systems considered include no-till, well-managed pasture, integrated crop-livestock, and integration with trees (i.e., crop-forestry, livestock-forestry, crop-livestock-forestry, and multistrata agroforestry). Out of 1200 papers mentioning GHGs and climate-smart systems, 74 contained reliable on-farm flux measurements. Most authors were Brazilians affiliated with Embrapa and public Universities. Studies concentrated on the Atlantic Forest and Cerrado, with scarce data for other biomes. Over half of the trials assessed individual GHG molecules and only one climate-smart system. Urochloa spp. and Avena spp. were the most studied forage genera, while soybeans and corn dominated annual crops. Eucalyptus spp. and beef cattle were common trees and animals. No-till, integrated crop-livestock, and agricultural integrations involving trees showed soil C–CH 4 influx from 0.8 to 1.0 kg ha−1 y−1. Transitioning from pasture monoculture to integrated systems decreased N–N 2 O emissions by up to 1.63 kg ha−1 y−1. Converting extensive grazed land to intensified-integrated systems reduced animal CH 4 intensity, with cuts of up to 122 g CH 4 per kg of average daily weight gain. Future research must urgently address methodological issues, such as de-standardization (e.g., 8–10 flux units found per GHG molecule) and the absence of crucial ancillary variables. In conclusion, adopting diversified climate-smart agri-systems shows potential to mitigate GHG emissions, but caution is advised when extrapolating our numerical findings due to limited data across Brazilian edaphoclimatic conditions. We urge scientists to prioritize frequent on-farm measurements of all three GHGs (CO 2 , N 2 O, and CH 4) along with agroecosystem C sequestration across multiple climate-smart systems, enabling reliable and comparable net GHG flux calculations to identify the most sustainable option. Advancing and standardizing GHG measurements in Brazil offer an opportunity to enhance GHGs inventory accuracy, calibrate models, and promote policies and investments that expand refined tropical climate-smart agriculture. [Display omitted] • We systematically reviewed GHG measurements in Brazilian climate-smart agri-systems. • Well-managed pastures, no-till, and integration-based systems mitigate GHG emissions. • Brazilian GHG dataset incompletely represents systems and environmental complexities. • Producing agri-GHG field data is still vital for policies, investments, and C market. • Future GHG research should standardize flux units and include ancillary variables.

Objective: To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI. Materials and Methods: Searches in PubMed, Ovid, Web of Science, Scopus, Lilacs and gray literature were performed. Data extraction was conducted by two researchers. Risk of bias assessment employing the Newcastle‐Ottawa Scale and meta‐analysis were conducted. Results were provided with mean difference (MD), odds ratio (OR) and 95% confidence interval (CI). Strength of evidence was determined. Results: Six cross‐sectional studies were included. In comparison with individuals without OI, the group with OI had 19.69‐fold greater chance of exhibiting Angle Class III malocclusion (OR = 19.69, CI: 9.00–43.09) and presenting anterior crossbite greater (MD = 6.08, CI: 2.40–9.77). Individuals without OI had a significantly greater ANB angle (MD = 3.88, CI: 1.15–6.61) and SNA angle (MD = 2.11, CI: 0.24–3.98) in comparison with those with OI. No difference between groups was found for SNB (MD = −0.50, CI: −2.21 to 1.21) and open bite (MD = 0.98, CI: −0.29 to 2.25). Most studies included had moderate methodological quality. Strength of evidence was low or very low. Conclusions: The occurrence of Angle Class III malocclusion and anterior crossbite was greater among individuals with OI compared to those without OI. These findings can assist stakeholders about the occlusal abnormalities affecting OI individuals. [ABSTRACT FROM AUTHOR]

Objective: To determine, through a systematic review with meta‐analysis, the prevalence of food addiction (FA) using the Yale Food Addiction Scale (YFAS) and its derivatives exploring possible factors associated with the prevalence of FA in several contexts. Methods: The following databases were searched: MEDLINE, ScienceDirect, LILACS, PsycArticles, CENTRAL, Greylit.org, and OpenGrey.eu. Studies that assessed FA using YFAS were included. Two independent reviewers assessed the eligibility of each report. Random‐effects meta‐analysis was performed to calculate the weighted prevalence of FA. Subgroup analyses and meta‐regression were conducted to explore sources of heterogeneity. Results: Of the 6425 abstracts reviewed, 272 studies were included. The weighted mean prevalence of FA diagnosis was 20% (95% CI: 18%; 21%). The prevalence of FA was higher in individuals with clinical diagnosis of binge eating (55%; 95% CI 34%; 75%). The prevalence in clinical samples was higher compared to non‐clinical samples. Two studies included children only and no studies included only elderly people. Conclusions: Food addiction is a topic in which there has been a significant growth in studies. The highest prevalence was found in the group of participants with eating disorders and weight disorders. More studies with children and the elderly are needed. Highlights: There was an exponential increase in the number of scientific publications related to food addiction.The overall prevalence of food addiction was 20%.The highest prevalence of food addiction was found in the group with a clinical diagnosis of binge eating.Studies conducted in clinical settings in general also showed high prevalence of food addiction.

Nurses play an important role in healthcare, and the Nursing Outcomes Classification is a key tool for the standardization of care. This study aims to validate the nursing outcome "Neurological Status" for patients with cerebrovascular diseases. A methodological study was performed in four phases. In Phase 1, the relevance of the indicators was evaluated by seven specialists and the modified kappa coefficient and content validity index were calculated. In Phase 2, conceptual and operational definitions were formulated. In addition, their content was validated with a focus group in Phase 3. In Phase 4, the results were applied in clinical practice and convergence with the National Institute of Health Stroke Scale was verified. The reliability was measured by Cronbach's alpha. Of the 22 initial indicators, 6 were excluded. The focus group suggested changes in the definitions and the exclusion of two indicators. In Phase 4, only 13 indicators were validated due to the impossibility of measuring intracranial pressure. A strong correlation between the two scales and agreement among all the indicators were observed. Following the specialists' review, the nursing outcome was reliable and clinically validated with 13 indicators: consciousness, orientation, language, central motor control, cranial sensory and motor function, spinal sensory and motor function, body temperature, blood pressure, heart rate, eye movement pattern, pupil size, pupil reactivity, and breathing pattern.

Introduction: The Activities-specific Balance Confidence scale is the most used tool to quantify balance confidence, a psychological factor related to balance impairment among older adults. Objective: To investigate the validity and reliability of the original and short versions of the Brazilian Activities-specific Balance Confidence scales, to determine cutoff points for balance impairments and to identify the determinants of balance confidence of community-dwelling older adults. Methods: The validity of both versions of the scales was verified by correlating its results with postural balance, fear of falling and mobility (n = 105). Both scales were administered with a 30 min (interrater reliability, n = 158) and 1-week intervals (intrarater reliability, n = 105). Receiver operating characteristic curve was used to determine the cutoff points, and linear regression was applied to identify the determinants of balance confidence. Results: The Brazilian versions of the scale correlated to postural balance, fear of falling and mobility (p <.05). Excellent interrater (α = 0.946, 95% CI: 0.902–0.976; α = 0.932, 95% CI: 0.918–0.960) and intrarater reliability (α = 0.946, 95% CI: 0.905–0.960; α = 0.952, 95% CI: 0.921–0.965) were found for the original and short versions. Values of ≤67% (sensitivity: 81%, specificity: 77.4%) and ≤44% (sensitivity: 87.5%, specificity: 82.1%) were observed to identify balance impairments for the original and short versions of the scale. Physical inactivity, fear of falling, imbalance sensation, and number of falls are the main determinants of balance confidence. Conclusion: Both scales are valid and reliable to assess balance confidence. Cutoff points to identify balance impairments were determined and some factors may act as possible predictors of balance confidence. [ABSTRACT FROM AUTHOR]

The updated meta‐analysis was conducted to further verify the effect of varicocele on sperm DNA damage, supplying clinicians and researchers with high‐grade evidence. The sperm DNA damage was evaluated by DNA fragmentation index (DFI), associated with the male fertility capability tightly. PubMed, Web of Science and Cochrane Library were searched extensively for eligible studies with the search terms: varicocele, sperm DNA and sperm DNA damage. Finally, a total of 12 studies were included in our meta‐analysis with a total of 845 patients diagnosed with varicocele and 2,377 healthy controls. A statistical difference of DFI between varicocele patients and healthy controls was found after pooling the data ((Standardised mean difference) SMD: 1.40, 95%CI: 0.83–1.98, p <.0001), using the random effect model. We conducted subgroup analysis according to study region (Brazil and Other countries), detection methods of DFI (TUNEL, Comet, and SCSA), sample size (<50 and >50) and age (<30 and >30 years), based on substantial heterogeneity among eligible studies. The stability of pooled results was verified by sensitivity analysis. All these statistical analyses were conducted using Stata version 16.0. In conclusion, patients diagnosed with clinical varicocele had higher DFI than healthy controls, which means varicocele could impair sperm DNA, consequently the fertility potential of affected men.

Due to the high rainfall erosivity and highly erodible soils, water erosion is severe in Brazil. Soil and ecosystem degradation occurs when erosion exceeds on‐ and off‐site soil loss tolerances, with significant socioeconomic and environmental impacts. In the last 50 years, the Brazilian Cerrado had 53% of its original vegetation converted to agriculture and pastureland. Although erosion plot studies exist in the region, the data are fragmented and unexplored, hindering the development of soil conservation policies. The objective of the present research was to compile, systematize, and statistically analyze the existing erosion plot data in the Brazilian Cerrado, correlating the observed results with different environmental and management factors, and with the corresponding soil loss tolerances. Twenty runoff plot datasets of the Brazilian Cerrado, encompassing 5 states, 10 sites, 108 plots, and 360 plot·years were compiled and thoroughly analyzed. Mean annual rainfall, runoff, and soil loss were 1443.5 mm year−1, 83.1 mm year−1, and 8.9 Mg ha−1 year−1, respectively. After the data were normalized with respect to plot length, steepness, and climate, runoff and soil loss were found to be significantly higher in soils with impermeable horizons and in land uses without permanent soil cover (p < 0.05). Erosion under permanently covered plots was below the on‐ and off‐site soil loss tolerances. A power equation provided the best fit between plot runoff and soil loss (R2 = 0.71; p < 0.05), indicating that runoff volume, easier to estimate, could be used as a proxy for upslope erosion. Although erosion plot data cannot be extrapolated to the whole landscape, the research results provide useful elements for the development of sound conservation policies in the Cerrado and in other similar savannas of the world.

Background: Iron deficiency anemia (IDA) is among the most common micronutrient deficiencies in women of childbearing age and may affect children's development. Brazil has several national programs to tackle this condition, such as food fortification and supplementation for pregnant women, but IDA prevalence in this population has not been systematically reviewed. We sought to determine the prevalence of IDA in Brazilian women of childbearing age through a systematic review with metanalysis. Methodology: A protocol was previously published on the PROSPERO platform under the code CRD42020200960. A panel of the National Council for Scientific and Technological Development (CNPq) approved the protocol of this study under the public call number 26/2019. The main databases searched were MEDLINE, Web of Science, Scopus, Lilacs, and SciELO. In gray literature, the Brazilian Digital Library of Theses and Dissertations and the annals of the Brazilian Congress of Epidemiology and the Brazilian Congress of Public Health were accessed. The search strategy involved terms related to the condition (IDA) and the age group of the population of interest (teenagers and adults). Studies that had assessed the prevalence of IDA in Brazilian women of childbearing age (10-49 years) were included. Three independent reviewers read all titles and abstracts and extracted data from the included studies. Random effects meta-analyses using the Freeman-Tukey arcsine transformation were carried out with prevalence data, and meta-regression was conducted to test for subgroup differences. The quality of the studies was assessed using the Newcastle-Ottawa Scale. Results: From 21,210 unique records screened, 237 full-texts were retrieved, of which 91 were included in the qualitative synthesis, and 83 were included in the metaanalysis. The overall IDA prevalence was 25% (95% CI [23-28], 83 studies). The subgroup of studies that used random sampling showed a prevalence of 22% (95% CI [17-27], 22 studies), whereas in those with non-random sampling, the prevalence was 27% (95% CI [23-30], 61 studies), without significant differences between subgroups in the metaregression (P = 0.13). High prevalence of IDA were found in the subgroups of studies conducted in the North and Northeast regions (30%; 95% CI [24-37]; seven studies, and 30%; 95% CI [26-34]; 27 studies, respectively), in studies conducted with indigenous population (53%; 95% CI [27-78], four studies), and with studies that had their collections after 2015 (28%; 95% CI [23-34], nine studies). Conclusions: IDA in women of childbearing age remains a public health problem in Brazil, especially in the North and Northeast region. The national programs should be strengthened and more thoroughly supervised to decrease this condition nationally. [ABSTRACT FROM AUTHOR]

We conducted a systematic review and meta-analysis of studies assessing HCV infection rates in haemodialysis patients in Brazil (Prospero CRD #42021275068). We included studies on patients under haemodialysis, comprising both convenience samples and exhaustive information from selected services. Patients underwent HCV serological testing with or without confirmation by HCV RNA PCR. Exclusion criteria were the following: absence of primary empirical information and studies without information on their respective settings, study year, accurate infection rates, or full specification of diagnostic tests. Studies with samples ≤ 30 and serial assessments with repeated information were also excluded. Reference databases included PubMed, LILACS, Scopus, and Web of Science for the period 1989–2019. A systematic review was carried out, followed by two independent meta-analyses: (i) studies with data on HCV prevalence and (ii) studies with a confirmatory PCR (i.e., active infection), respectively. A comprehensive set of different methods and procedures were used: forest plots and respective statistics, polynomial regression, meta-regression, subgroup influence, quality assessment, and trim-and-fill analysis. 29 studies and 11,290 individuals were assessed. The average time patients were in haemodialysis varied from 23.5 to 56.3 months. Prevalence of HCV infection was highly heterogeneous, with a pronounced decrease from 1992 to 2001, followed by a plateau and a slight decrease in recent years. The summary measure for HCV prevalence was 34% (95% CI 26–43%) for studies implemented before 2001. For studies implemented after 2001, the corresponding summary measure was 11% (95% CI 8–15%). Estimates for prevalence of active HCV infection were also highly heterogeneous. There was a marked decline from 1996 to 2001, followed by a plateau and a slight increase after 2010. The summary measure for active HCV infection was 19% (95% CI 15–25%) in studies carried out before 2001. For studies implemented after 2001, the corresponding summary measure was 9% (95% CI 6–13%). Heterogeneity was pervasive, but different analyses helped to identify its underlying sources. Besides the year each study was conducted, the findings differed markedly between geographic regions and were heavily influenced by the size of the studies and publication biases. Our systematic review and meta-analysis documented a substantial decline in HCV prevalence among Brazilian haemodialysis patients from 1992 to 2015. CKD should be targeted with specific interventions to prevent HCV infection, and if prevention fails, prompt diagnosis and treatment. Although the goal of HCV elimination by 2030 in Brazil remains elusive, it is necessary to adopt measures to achieve micro-elimination and to launch initiatives towards targeted interventions to curb the spread of HCV in people with CKD, among other high-risk groups. This is of particular concern in the context of a protracted COVID-19 pandemic and a major economic and political crisis. [ABSTRACT FROM AUTHOR]

The relevance of organizational justice for the improvement of the relationship between workers and organizations has given the theme a prominent role on the international stage in recent decades. In Brazil, discrepancies between national and foreign contributions were pointed out by the last review on the subject, in 2005. Thus, this study analyzed the Brazilian scientific production on organizational justice, focusing on the dimensions of the organizational justice, the theoretical background, and the relationships investigated. A semi-systematic literature review was carried out in 19 journals (1996-2018). The results showed significant differences between national and international production. A national research agenda is presented, highlighting the need for studies exploring the antecedents and the effects of the process of mediation and interaction of justice and a better theoretical foundation.

Memory training is an alternative for cognitive improvement with elderly, currently evidenced in Brazilian research. Nevertheless, there is no verification of the differences between types of training, in order to identify the effectiveness of different strategies in intervention. Therefore, this paper seeks to compare strategies adopted in the Brazilian context. A meta-analysis was carried out, evaluating the effect size, publication bias and heterogeneity of the studies. The results indicate a statistically insignificant effect from insignificant to moderate on the worked memory subsystems, although with a moderate and significant effect on incidental memory. The presence of bias in publications and high heterogeneity between studies are indicated. Subsequent meta-analyses should associate the results with methodological characteristics of the works.

Purpose: The prevalence of bruxism in children varies considerably. The purpose of this study was to synthesize evidence of the prevalence of bruxism in Brazilian children and consider how proportions differ between genders, assessment approaches, and geographical regions. Methods: A search was conducted using five databases and in gray literature. Two independent investigators selected the studies and extracted data. The risk of bias was assessed via the Joanna Briggs Institute tool for studies on prevalence. The certainty of the evidence was evaluated using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results: Twenty-two cross-sectional studies were included after a twostep selection. Overall, 13,076 children from all regions of the country were assessed. The risk of bias ranged from high to low. Data were pooled in a random-effect model and resulted in an overall prevalence of sleep and awake bruxism of 25.8 percent (95 percent confidence interval [95% CI] equals 22.2 to 29.4; I2 equals 96 percent; prediction interval equals 0.07 to 0.44) and 20.1 percent (95% CI equals 18.0 to 22.3; I2 equals 30 percent; prediction interval equals 0.18 to 0.22), respectively. Subgroup and sensibility analysis showed distribution similarity between genders (P=0.96), assessment approaches (P=0.88), and geographical regions (P=0.44). Conclusions: "Possible" and "probable" sleep bruxism affects one in four Brazilian children, and there is evidence with a low level of certainty that its prevalence does not vary between genders, assessment approaches, or geographical regions. The distribution of bruxism is still an unknown subject and presumably occurs because of individual rather than regional or collective factors. [ABSTRACT FROM AUTHOR]
