RESUMEN

OBJECTIVE: The purposes of this study were to assess trends in the level of evidence of the abstracts presented at a major Brazilian plastic surgery annual meeting, and evaluate the factors associated with a higher level of evidence. METHODS: Abstracts (n = 400) presented at the 2010 to 2013 Brazilian Congresses of Plastic Surgery were analyzed for level of evidence (levels I-V). All abstracts were also classified into a higher (levels I and II) or lower (levels III, IV, and V) level of evidence. Bivariate and multivariate analyses were applied to evaluate the possible determinants (year, period, number of authors, number of subjects, plastic surgery topic, and presence of statistical analysis) of higher level of evidence. RESULTS: The weighted average level of evidence was 3.39, with a significant (all P <0.05) overall predominance in the proportion of level of evidence III and lower level of evidence. There was a significant (all P <0.05) increase in the proportion of level of evidence II and higher level of evidence in the evaluated years and periods. Bivariate and multivariate analyses revealed that the year 2013, period 2012 to 2013, ≥6 authors/abstracts, and presence of statistical analysis to be the most significant (all P <0.05) predictive factors of higher level of evidence. CONCLUSION: Brazilian plastic surgery meeting abstracts demonstrated an overall predominance of lower level of evidence and a trend to increase the higher level of evidence, whereas the year 2013, period 2012 to 2013, ≥6 authors/abstracts, and the presence of statistical analysis were determinants of higher level of evidence.

RESUMEN

OBJECTIVE: The aim of this study is to assess the public perception of plastic surgeons (PS) as craniofacial surgery specialists. METHODS: Members of the public (N = 1514) were asked to choose 1 or 2 specialists that they perceived to be an expert for 13 craniofacial surgery-related scenarios. Response patterns were distributed as "plastic surgeon alone" (PS alone), "PS combined with other specialists", or "no plastic surgeon" (No PS). Sociodemographic data, previous plastic surgery contact, and source of reported information were also collected. RESULTS: "Plastic surgeon alone" was significantly (all P < 0.05) more recognized as experts than all other response patterns particularly in congenital anomalies-related scenarios (83.33%). There was a significantly (all P < 0.05) poor understanding of the role of PSs in head/neck infection management, chronic facial palsy management, dental disease management, head and neck cancer surgery, vascular malformation surgery, and facial fracture surgery. Sex, age, education level, health care professional, prior plastic surgery contact, and source of reported information were not significant (all P < 0.05) determinants of "PS" as the response in bivariate and multivariate analyses. CONCLUSIONS: Public recognized PSs as experts primarily in treatment of congenital cleft and craniofacial anomalies, but as the overall scope of craniofacial surgery practice was poorly understood and known, improved public education is needed.

RESUMEN

BACKGROUND: The purpose of this survey was to assess the influence of aesthetic surgery "reality television" shows viewing on the public's perception of the scope of plastic surgery practice. METHODS: Perceptions of the scope of plastic surgery (33 scenarios), aesthetic surgery "reality television" viewing patterns ("high," "moderate," or "low" familiarity, similarity, confidence, and influence viewers), sociodemographic data, and previous plastic surgery interaction were collected from 2148 members of the public. Response patterns were created and bivariate and multivariate analyses were applied to assess the possible determinants of overall public choice of plastic surgeons as experts in the plastic surgery-related scenarios. RESULTS: Both "plastic surgeons" and "plastic surgeons alone" were the main response patterns (all p < 0.05) in ten (83.3%) aesthetic interventions-related scenarios. "Plastic surgeons" and "plastic surgeons alone" were significantly (all p < 0.05) more identified as experts in ten (47.6%) and eight (38.1%) general/reconstructive-related scenarios, respectively. There were positive (health care professionals and prior plastic surgery interaction) and negative ("high-familiarity" viewers, "high-influence" viewers, "high-confidence" viewers, and "high-similarity" viewers) significant (all p < 0.05) determinants of response plastic surgeons in the bivariate and multivariate analyses. CONCLUSION: Aesthetic surgery "reality television" viewing negatively influences the public perception of the broad scope of plastic surgery. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMEN

INTRODUCTION: the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates. METHODS: Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors. RESULTS: 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones. CONCLUSION: the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

RESUMEN

Insect viruses have been used to protect crops and forests worldwide for decades. Among insect viruses, isolates of Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) have proven potential for the control of Spodoptera frugiperda (J. E. Smith) (FAW) (Lepidoptera: Noctuidae), a pest of many economically essential crops across several continents. Mass production of SfMNPV depends on an in vivo system using host insect rearing. However, many factors can limit its production, including abiotic factors and host characteristics, such as the stage of development and an antagonist intraspecific interaction. Thus, to improve in vivo production, we verified the most suitable larval age to inoculate the virus and the influence of incubation temperature on viral production. Subsequently, cannibal behavior was verified in FAW larvae reared at different densities, while reproducing the conditions of the best treatments. The highest viral yield occurred when FAW larvae were inoculated at 10 and 8 days old and incubated at 22 °C and 25 °C, respectively. Nonetheless, survival (lethal period in days) and cannibal behavior were positively influenced by larval development, which potentially increases the load of contamination and requires larval individualization for these production conditions. In contrast, 4-day-old larvae, which were inoculated and incubated at 31 °C, also demonstrated high viral production, with lower rates of cannibalism and death on the same day, thereby showing potential. The information presented in this study is useful for the optimization of the in vivo production systems of SfMNPV.

RESUMEN

BACKGROUND: Microscopy and enzyme-linked immunosorbent assay (ELISA) are routinely used for Cryptosporidium diagnosis, without differentiating the parasite species. METHODS: Children's feces were analyzed by modified Ziehl-Neelsen (mZN) and ELISA for Cryptosporidium diagnosis and by polymerase chain reaction-restriction fragment length polymorphism for species identification. RESULTS: Cryptosporidium frequency was 2.6%. The sensitivity and specificity of ELISA were 85.7% and 99.7%, respectively, with excellent concordance with mZN (kappa=0.854). Parasite species were characterized as Cryptosporidium hominis (78.3%), Cryptosporidium felis (17.4%), and Cryptosporidium parvum (4.3%). CONCLUSIONS: Coproantigen ELISA is as efficient as mZN for Cryptosporidium diagnosis. Cryptosporidium genotyping suggests anthroponotic and zoonotic transmission to children.

RESUMEN

INTRODUCTION: Being born small for gestational age (SGA) implies an increase in the childhood morbidity and mortality rates, in addition to being related to changes in the pattern of growth and body composition, which may be associated with the development of risk factors linked to metabolic diseases. Aim of the study: To describe the development of anthropomorphic indicators of children born at full term, small (SGA) or appropriate for gestational age (AGA), up to the sixth month of life, and again when they reached school-age. MATERIAL AND METHODS: This was a prospective cohort study, with 31 children (19 SGA, and 12 AGA), recruited in public maternity hospitals. Subsequently they were attended at an outpatient clinic on a monthly basis, by a multidisciplinary team in the first year of life. These children were re-evaluated when they reached school-age. RESULTS: Both groups showed high percentages of exclusive breastfeeding in the first months of life. Group SGA showed intense early recovery of the growth indicators, characterizing recovery of growth in the first 6 months of life. However, at school-age, they were still smaller, lighter, with a lower quantity of body fat and muscle mass than those born AGA. There was predominance of appropriate anthropometric growth and body composition indicators at school-age, even in Group SGA. Conclusion: At school-age, the children of this study showed no major alterations related to anthropometry.

RESUMEN

INTRODUCTION: Giardia duodenalis is an intestinal protozoan with a high prevalence in children of developing countries. Molecular studies revealed a great genetic diversity of G. duodenalis, with assemblages A and B found mainly in humans. Despite its importance, the information on the molecular epidemiology of human giardiasis is still limited in Brazil. OBJECTIVE: To characterize G. duodenalis molecular isolates in children from Salvador, Bahia, Brazil. MATERIALS AND METHODS: Giardia duodenalis positive fecal samples were obtained from 71 children from two day care centers and 39 users of a clinical analysis laboratory. Samples were analyzed by PCR-RFLP of the glutamate dehydrogenase (gdh) and beta-giardin genes and by the sequencing of beta-giardin. RESULTS: Of the 110 G. duodenalis samples, 80 (72.7%) amplified one or both target genes. Of these, 62 (77.5 %) were identified as assemblage A and 18 (22.5%) as assemblage B. The subassemblage AII was identified in 58.8% (n=47) of isolates followed by the sub-assemblage AI (18.8%, n=15), BIV (11.2%, n=9), and BIII (5.0%, n=4). The AII sub-assemblage was the most frequent in children of both day care centers whereas AI was found only in the group attended at the clinical laboratory. Sub-assemblage AII predominated in children under two years. CONCLUSIONS: The higher frequency of AII sub-assemblage suggests that anthroponotic transmission is more common in Salvador, but that zoonotic transmission pathways are also present and a change in susceptibility to different molecular patterns of Giardia may occur during child growth.


Introducción. Giardia duodenalis es un protozoo intestinal de gran prevalencia en los niños de los países en desarrollo. En estudios moleculares se ha evidenciado la gran diversidad genética de G. duodenalis y se han identificado los conjuntos A y B, principalmente en humanos. A pesar de su importancia, el conocimiento de la epidemiología molecular de la giardiasis humana aún es limitado en Brasil. Objetivo. Caracterizar los aislamientos moleculares de G. duodenalis de muestras tomadas a niños de Salvador, Bahía, Brasil. Materiales y métodos. Las muestras fecales positivas para G. duodenalis se obtuvieron de 71 niños de dos guarderías y de 39 usuarios de un laboratorio de análisis clínicos. Las muestras se analizaron mediante PCR-RFLP de los genes gdh y beta-giardin, y secuenciación de beta-giardin. Resultados. De las 110 muestras de G. duodenalis, en 80 (72,7 %) se amplificaron uno o ambos genes. De estos, 62 (77,5 %) se identificaron como pertenecientes al conjunto A y 18 (22,5 %) al B. El subconjunto AII se identificó en el 58,8 % (n=47) de los aislamientos, seguido del AI en el 18,8% (n=15), el BIV en el 11,2% (n=9) y el BIII en el 5,0% (n=4). El subconjunto AII fue el más frecuente en los niños de ambas guarderías, en tanto que el AI solo se encontró en el grupo atendido en el laboratorio clínico. El subconjunto AII predominó en los niños menores de dos años. Conclusiones. La mayor frecuencia del subconjunto AII sugiere que la transmisión antroponótica es más común en Salvador, pero también existen vías de transmisión zoonóticas, y que pueden ocurrir cambios en la sensibilidad frente a diferentes patrones moleculares de Giardia durante el crecimiento infantil.

RESUMEN

Introduction: Gender inequality occurs in all spheres of society, which is no different in the medical field. Abstract presentations in congress are the vanguard of scientific knowledge, an integral part of topic discussion, and, ideally, culminate in the publication of these works as complete manuscripts. Objective: The objective of this study is to evaluate the role played by women in the presentation of scientific works at the Brazilian Society of Coloproctology congress and in the works published from these presentations. Methods: The bibliometric evaluation of the presented abstracts in the editions from 2015 to 2018 of the Brazilian Congress of Coloproctology was used, along with the works later published from these presentations. Gender identification data was extracted from the authors of the abstracts through their names and research for conference on the Lattes and Google Scholar platforms. The collected data was on the number of female participants and their order of authorship of abstracts and publications, evaluating possible changes when publication occurs. Results: A total of 1,336 abstracts were analyzed, with 91.6% of female authors. When publication occurs, women's presence dropped to 75.2% and suffered a change of order in the position of authorship to one of lesser relevance in 38.1%. Conclusion: Women's participation occurs in most abstracts. However, this proportion undergoes unfavorable changes when these works are published, either by changing the order of authorship, when women leave main positions and become coauthors, or are removed from the complete manuscript's publication.

RESUMEN

OBJECTIVES: We aimed to evaluate the effects of cataract surgery on cardiac autonomic modulation. METHODS: A cross-sectional and analytical study was conducted at the Hospital Maria Braido in the city of São Caetano do Sul, São Paulo, between 2015 and 2016. We investigated 19 patients of both sexes who were all over 50 years old; all patients had a diagnosis of senile or bilateral cataracts and were recommended to undergo implantation of the intraocular lens. Heart rate variability (HRV) was evaluated before, during and after cataract surgery. RESULTS: There were no significant changes in the time and geometric domains of HRV before, during or after surgery. The high-frequency (HF) band in normalized units (nu) on the spectral analysis significantly increased (p=0.02, Cohen's d=0.9, large effect size). However, the low-frequency (LF) band in nu significantly decreased during surgery (p=0.02, Cohen's d=0.9, large effect size). CONCLUSION: Throughout the intraocular lens implantation cataract surgery, there was an increase in parasympathetic modulation and a decrease in the sympathetic component of the heart rate (HR). We propose that this result is attributable to the supine position of the patients during surgery and the trigeminal reflex.

RESUMEN

Introduction: The purpose of this retrospective bibliometric study was to assess the discrepancies between coloproctology surgery meeting abstracts and subsequent full-length manuscript publications. Methods: Abstracts presented at the Brazilian Congress of Coloproctology Surgery from 2015 to 2019 were compared with matching manuscript publications. Discrepancies between the abstract and therefore the subsequent manuscript were categorized as major (changes within the purpose, methods, study design, sample size, statistical analysis, results, and conclusions) and minor (changes within the title, authorship, and number of female authors) variations. Results: The conversion rate of abstracts in published manuscripts was 6,9% (121 abstracts). There were inconsistencies between the study title (66,1%), authorship (69,5%), study design (3,3%), sample size (39,2%), statistical analysis (24,8%), results (25,6%), and conclusions (12,4%) of manuscripts compared with their corresponding meeting abstracts. Conclusion: As changes occur before manuscript publication of coloproctology surgery meeting abstracts, caution should be exercised in referencing abstracts or altering surgical practices based on abstracts content.

RESUMEN

Introduction: Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods: A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results: A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions: Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

RESUMEN

Introduction: The presentation of abstracts in a congress is an important step for the dissemination of scientific information. The American Congress of Coloproctology is promoted by the American Society of Colon & Rectal Surgeons (ASCRS), and it is the largest in number of participants within the specialty, followed by the Brazilian Congress of Coloproctology. The present study aims to evaluate variables related to the quality of the scientific production of the abstracts presented in these two events and their conversion rate to published manuscripts. Materials and Methods: The present bibliometric study assesses secondary data from the review of abstracts presented in these 2 important conferences in 2016, followed by a research of the publications from these congress presentations. Results: The total number of abstracts evaluated was 854. The rate of articles containing statistical analyses was of 73.7% in the American congress, and of 34.1% in the Brazilian congress. Multicentric studies were more prevalent in the American congress (23.1%). Regarding study design, the most common were case reports in the Brazilian (44.8%) congress and retrospective studies in the American congress (67.7%). As for the works presented, the rate of conversion into full manuscripts in the American congress was of 24.2% compared with 10.6% in the Brazilian congress. Most papers from the American congress (93.7%) have citations compared with 68.6% of the other event evaluated. Conclusion: The scientific performance demonstrated by the conversion rate of abstracts into publications is below ideal, mainly in relation to the Brazilian meeting; yet, there were significant differences between the two events in terms of the profile of the presentations and several variables analyzed.

RESUMEN

ABSTRACT Introduction: the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates. Methods: Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors. Results: 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones. Conclusion: the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

A taxa de conversão em artigos publicados de resumos apresentados em congressos é um indicador para avaliar a qualidade científica de seus eventos. O objetivo deste estudo é avaliar características bibliométricas dos resumos apresentados no Congresso Brasileiro de Coloproctologia e determinar os fatores que afetam as taxas de publicação. Métodos: avaliação retrospectiva de todos os resumos apresentados nos Congressos Brasileiros de Coloproctologia dos anos de 2015 a 2019. Análise de múltiplas bases de dados para estimar a taxa de conversão dos trabalhos apresentados, assim como variáveis associadas à conversão dos resumos em manuscritos completos através de análises bivariadas e multivariadas desses preditores. Resultados: foram analisados 1756 resumos. A maioria dos estudos são retrospectivos, séries ou relatos de casos e até experiência pessoal. A taxa de conversão foi de 6,9%. A presença de análise estatística foi o dobro para os resumos publicados frente aos não publicados. Conclusão: os dados apresentados demonstram uma baixa produtividade científica da especialidade, já que as pesquisas realizadas não são publicadas, em sua maioria, como manuscritos completos. Os fatores preditores de publicação dos resumos foram: estudos multicêntricos, estudos contendo análise estatística, desenhos de estudo de maior nível de evidência e estudos premiados pelo congresso.

RESUMEN

Rotavirus is a major cause of infectious diarrhea in infants and young children. The objective of this study was to characterize the genotypes of Human Rotavirus found in children hospitalized with acute diarrhea in the Pediatric Hospital Prof. Hosannah de Oliveira of the UFBA in Salvador, Bahia, Brazil, during the years of 1999, 2000 and 2002. Fecal samples were analyzed (n=358) by methods EIARA and SDS-PAGE for detection of Rotavirus. Positive samples of one or two of these methods (n=168) were submitted to RT-PCR and Multiplex-Nested PCR to determine genotypes G and P. A hundred sixty-eight (46.9%) samples were positive and 190 (53.1%) negative. Only 17 (4.7%) samples had divergent results. The distribution of genotypes G during the first year, showed that the genotype G9 was present in 96,8% of the analyzed samples, in the second year, it was responsible for 96% and in the third year, 88,1%. The characterization of genotypes P demonstrated that the genotype P1A[8] was the most outstanding in all years. In this study we discuss the benefit to control the genotypes of Rotavirus through the molecular characterization for the development of potential vaccines.

RESUMEN

Selection of value chain strategies by development practitioners and value chain participants themselves has been restricted to preset types of upgrading. This paper argues for an extension of the range of strategy solutions to value chains. An empirical application identifies successful strategies for honey value chains in Brazil for 2015-2020. Strategy and performance indicators were selected using the value chain Structure-Conduct-Performance (SCP) framework. Experts' opinion was elicited in a Delphi for business scenarios, and adaptive conjoint analysis was used to identify strategies for increasing production growth and local value-added. This study identifies important strategies beyond upgrading typologies, and finds that important strategies differ by performance goal and scenario. The value chain SCP allows searching for promising strategies towards performance-the "better deal"-in an integrated way.

Methods: Children's feces were analyzed by modified Ziehl-Neelsen (mZN) and ELISA for Cryptosporidium diagnosis and by polymerase chain reaction-restriction fragment length polymorphism for species identification. Results: Cryptosporidium frequency was 2.6%. The sensitivity and specificity of ELISA were 85.7% and 99.7%, respectively, with excellent concordance with mZN (kappa=0.854). Parasite species were characterized as Cryptosporidium hominis (78.3%), Cryptosporidium felis (17.4%), and Cryptosporidium parvum (4.3%). Conclusions: Coproantigen ELISA is as efficient as mZN for Cryptosporidium diagnosis. Cryptosporidium genotyping suggests anthroponotic and zoonotic transmission to children.

RESUMEN

Introdução: doenças Cardiovasculares são as principais causas de morte no mundo. Apesar da redução da incidência e mortalidade por DCV no século XX, os valores permanecem elevados no século XXI. No Brasil, há lacuna de estudos populacionais que estimaram as taxas padronizadas de mortalidade por doenças cardiovasculares em adultos jovens.Objetivo: avaliar a tendência da mortalidade por doenças cardiovasculares em adultos jovens, segundo sexo, faixa etária e regiões do Brasil.Método: estudo de séries temporais com uso de dados secundários oficiais dos Sistemas de Informações sobre Mortalidade (SIM). Foram consideradas todas as mortes por doenças cardiovasculares (I00-I-99) em adultos jovens faixa etária 20-49 anos, residentes no Brasil, no período de 01 de janeiro de 2008 a 31 de dezembro de 2017. Os dados foram extraídos do Departamento de Informática do SUS (DATASUS). Foi utilizado o modelo de regressão Prais-Winsten e calculada a Variação Percentual Anual (VPA). Todas as análises foram realizadas no software STATA 14.0.Resultados: durante período 2008-2017, foram identificadas 294.232 mortes (8,7%) por doença cardiovascular em adultos jovens com idade entre 20-49 anos. Identificou-se a redução da mortalidade por DCV em todas as regiões do Brasil, exceto nos indivíduos de 20-24 anos, residentes na região Nordeste, a qual apresentou aumento (VPA: 2,45%) (p<0,05) 2013-2017. A maior variação da tendência de mortalidade ocorreu na região Sul (VPA: -25,2%). Enquanto a menor variação de tendência da mortalidade ocorreu na região Nordeste (VPA: -8,8%). O declínio anual foi menor no segundo quinquênio (2013-2017) em comparação ao primeiro (2008-2012). Além disso, o declínio foi mais acentuado entre as mulheres (VPA: -2,51%) (p<0,05) 2008-2012 e em adultos jovens com idade entre 40-44 anos (VPA: -2,91%) (p<0,05) 2008-2012. Ademais, a tendência de mortalidade por DCV se estabilizou a partir de 2013 no sexo masculino (p>0,05).Conclusão: os resultados demonstram tendência decrescente da mortalidade por Doença Cardiovascular em adultos jovens no Brasil, entre 2008-2017. Conclui-se que existe desigualdade na tendência de mortalidade por DCV segundo sexo, faixa etária e regiões do Brasil.


Introduction: cardiovascular diseases are the leading causes of death in the world. Despite the reduction in CVD incidence and mortality in the 20th century, the values remain high in the 21st century. In Brazil, there is a gap in population studies that estimated standardized mortality rates from cardiovascular diseases in young adults.Objective: to assess the trend in mortality from cardiovascular diseases in young adults, according to sex, age group and regions of Brazil.Methods: ecological time series study using official secondary data from Mortality Information Systems (SIM). All deaths from cardiovascular diseases (I00-I-99) in young adults aged 20-49 years, residing in Brazil, in the period from January 1, 2008 to December 31, 2017, were considered. Data were extracted from the Department of Informatics of the SUS (DATASUS). The Prais-Winsten regression model was used and the Annual Percentage Variation (APV) was calculated. All analyzes were performed in STATA 14.0 software.Results: during the period 2008-2017, 294,232 deaths (8.7%) from cardiovascular disease were identified in young adults aged 20-49 years. A reduction in CVD mortality was identified in all regions of Brazil, except for individuals aged 20-24 years, residing in the Northeast region, which showed an increase (APC: 2.45%) (p<0.05) 2013 -2017. The greatest variation in the mortality trend occurred in the South region (APC: -25.2%). While the smallest change in mortality trend occurred in the Northeast region (APC: -8.8%). The annual decline was smaller in the second quinquennium (2013-2017) compared to the first (2008-2012). Furthermore, the decline was more pronounced among women (APC: -2.51%) (p<0.05) 2008-2012 and in young adults aged 40-44 years (APC: -2.91%) (p<0.05) 2008-2012. Furthermore, the trend in CVD mortality stabilized from 2013 onwards in males (p>0.05).Conclusion: the results demonstrate a decreasing trend in mortality from Cardiovascular Disease in young adults in Brazil, between 2008-2017. It is concluded that there is inequality in the trend of mortality from CVD according to sex, age group and regions of Brazil.

RESUMEN

INTRODUCTION: The Brazilian popular habit of using plants to treat several health conditions is ancient. Passion fruit (Passiflora edulis) is widely used to treat, usually in an empiric basis, a variety of medical conditions. Anti-inflammatory activity of Passiflora edulis extract, similar to non-steroidal anti-inflammatory drugs (NSAID's), has been described. PURPOSE: To evaluate the effect of Passiflora edulis hydroalcoholic extract on the healing of midline abdominal incisions in rats by morphological and tensiometric methods. METHODS: Forty male Wistar rats were randomly allocated into two groups to either receive Passiflora edulis extract (study group, P) or saline (control group, C) intraperitoneally, in a single isovolumetric dose, after a standardized ventral midline laparotomy had been performed. The twenty rats of the control group as well as those twenty of the study group were divided into subgroups according to the time of sacrifice, either the 3rd PO day (P3, C3) or the 7th PO day (P7, C7). On day three and on day seven after surgery, the rats were sacrificed and the wound area was excised by a standardized protocol. The healing process of the specimens was evaluated macroscopically and histologically. The tensile strength was evaluated by a constant speed computerized tensiometer to determine the breaking strength and the deformation of the healing incision. RESULTS: The macroscopic examination did not show significant differences between study and control groups. Histologically, the C3 vs. P3 comparison showed the following differences: for the variables acute inflammation (p=0.045 in favor of C3), collagenization and capillary neoformation: p=0.001 e 0.001, respectively in favor of P3. Similarly, the C7 vs. P7 comparison showed the following differences for the variables acute inflammation (p=0.002 in favor of C7), chronic inflammation and capillary neoformation: p= 0.006 e 0.001, respectively in favor of P7. Tensiometrically, maximal breaking strength (C(máx)) on day seven of the study group was higher when compared to control group, (6.91 +/- 1.36 vs. 5.05 +/- 1.63, p=0.013). Maximal deformation strength (D(máx)) on day seven of the study group was higher when compared to control group (36.49 +/- 4.61 vs. 26.19 +/-5.74, p=0.001). CONCLUSION: Passiflora edulis extract enhances the healing of midline abdominal incisions in rats, especially the histological and tensiometric aspects.

RESUMEN

This article analyzes the mental health network in the city of Rio de Janeiro. It provides a report on the current status of the implementation of psychiatric reform and identifies progress, limitations and challenges in this area. Documentary research was carried out by examining official documents, ordinances, SUS databases, information that was available at the Superintendency of Mental Health of the city of Rio de Janeiro, and a literature review of Brazilian and international scientific articles. The results point to important advances in the de-institutionalization of care, with a substantial reduction in the numbers of psychiatric beds, and increased community facilities. However, the following significant challenges remain: the need for increased coverage by psychosocial care centers; the implementation of psychiatric beds in general hospitals; the integration of mental health with primary health care; the de-institutionalization of people who remain in hospitals for long periods; the expansion of the number of residential facilities; and an increase in the provision of specific services for people using alcohol and other drugs.
