ABSTRACT

ABSTRACT BACKGROUND: Congenital vascular anomalies and hemangiomas (CVAH) such as infantile hemangiomas, port-wine stains and brain arteriovenous malformations (AVMs) impair patients' lives and may require treatment if complications occur. However, a great variety of treatments for those conditions exist and the best interventions remain under discussion. OBJECTIVE: To summarize Cochrane systematic review (SR) evidence on treatments for CVAH. DESIGN AND SETTING: Review of SRs conducted in the Division of Vascular and Endovascular Surgery of Universidade Federal de São Paulo, Brazil. METHODS: A broad search was conducted on March 9, 2021, in the Cochrane Database of Systematic Reviews to retrieve any Cochrane SRs that assessed treatments for CVAH. The key characteristics and results of all SRs included were summarized and discussed. RESULTS: A total of three SRs fulfilled the inclusion criteria and were presented as a qualitative synthesis. One SR reported a significant clinical reduction of skin redness by at least 20%, with more pain, among 103 participants with port-wine stains. One SR reported that propranolol improved the likelihood of clearance 13 to 16-fold among 312 children with hemangiomas. One SR reported that the relative risk of death or dependence was 2.53 times greater in the intervention arm than with conservative management, among 218 participants with brain AVMs. CONCLUSION: Cochrane reviews suggest that treatment of port-wine stains with pulsed-dye laser improves redness; propranolol remains the best option for infantile hemangiomas; and conservative management seems to be superior to surgical intervention for treating brain AVMs.

ABSTRACT

Resumo Fundamento A baixa escolaridade tem sido considerada um fator de risco modificável significativo para o desenvolvimento de doenças cardiovasculares há bastante tempo. Apesar disso, ainda não se sabe muito sobre esse fator impactar ou não os desfechos após infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Objetivo Investigar se a escolaridade é um fator de risco independente para mortalidade em pacientes com IAMCSST. Métodos Os pacientes com diagnóstico de IAMCSST foram consecutivamente incluídos em uma coorte prospectiva (Brasília Heart Study) e categorizados de acordo com os anos dos quartis de estudo (0-3, 4-5, 6-10 e >10 anos). Os grupos foram comparados pelo teste t de Student para variáveis contínuas e qui-quadrado para categóricas. A incidência de mortalidade por todas as causas foi comparada com Kaplan-Meyer com regressão de Cox ajustada por idade, sexo e escore GRACE. Valores de p < 0,05 foram considerados significativos. SPSS21.0 foi utilizado para todas as análises. Resultados A média de escolaridade foi de 6,63±4,94 anos. Durante o período de acompanhamento (média: 21 meses; até 6,8 anos), 83 pacientes vieram à óbito (mortalidade cumulativa de 15%). A taxa de mortalidade foi maior entre o quartil inferior em comparação com aqueles do quartil superior [18,5 vs. 6,8%; RR 2,725 (IC 95%: 1,27-5,83; p=0,01)]. Na análise multivariada, a baixa escolaridade perdeu significância estatística para mortalidade por todas as causas após ajuste para idade e sexo, com RR 1,305 (IC 95%: 0,538-3,16; p=0,556), e após ajuste pelo escore GRACE com RR 1,767 (IC 95%: 0,797-3,91; p=0,161). Conclusão Investigar se a escolaridade é um fator de risco independente para mortalidade em pacientes com IAMCSST.


Abstract Background Low schooling has been considered an important modifiable risk factor for the development of cardiovascular disease for a long time. Despite that, whether this factor impacts the outcomes following ST-segment elevation myocardial infarction (STEMI) is poorly understood. Objective To investigate whether schooling stands as an independent risk factor for mortality in STEMI patients. Methods STEMI-diagnosed patients were consecutively enrolled from a prospective cohort (Brasilia Heart Study) and categorized according to years of study quartiles (0-3, 4-5, 6-10 and >10 years). Groups were compared by student's t test for continuous variables and qui-square for categorical. Incidence of all-cause mortality was compared with Kaplan-Meyer with Cox regression adjusted by age, gender, and GRACE score. Values of p < 0.05 were considered significant. SPSS21.0 was used for all analysis. Results The mean schooling duration was 6.63±4.94 years. During the follow-up period (mean: 21 months; up to 6.8 years), 83 patients died (cumulative mortality of 15%). Mortality rate was higher among the lowest quartile compared to those in the highest quartile [18.5 vs 6.8%; HR 2.725 (95% CI: 1.27-5.83; p=0.01)]. In multivariate analysis, low schooling has lost statistical significance for all-cause mortality after adjustment for age and gender, with HR of 1.305 (95% CI: 0.538-3.16; p=0.556), and after adjustment by GRACE score with an HR of 1.767 (95% CI: .797-3.91; p=0.161). Conclusion Low schooling was not an independent risk factor for mortality in STEMI patients.

ABSTRACT

Resumo O objetivo deste artigo é analisar o impacto do estigma e da discriminação diante do sofrimento psíquico de adolescentes LGBT. Estudo qualitativo em serviço ambulatorial especializado de Saúde Mental Infantojuvenil, da Atenção Secundária da Secretaria de Saúde do Distrito Federal. Participaram do estudo nove adolescentes. Entrevista em profundidade viabilizou a coleta de dados, cuja análise ocorreu com utilização do software Iramuteq e da Análise de Conteúdo de Bardin. Intolerância à identidade de gênero e orientação sexual, fundamentada na heteronormatividade, viola direitos humanos e constitui relevante determinante social em saúde, e a superação dos sofrimentos psíquicos apresentados, articulada com o respeito aos direitos humanos da comunidade LGBT, constitui importante vetor para enfrentamento das iniquidades em saúde na adolescência. A discriminação de adolescentes LGBT é um determinante social que também deve ser enfrentado pelos serviços em saúde, pois ocasiona prejuízos, como a evasão escolar, falta de oportunidades, perda do vínculo familiar e comportamento suicida.


Abstract The objective of this article is to analyze the impact of stigma and discrimination against the LGBT adolescents' psychic suffering. Qualitative study conducted in a specialized outpatient service of Child and Adolescent Mental Health Secondary Care of the Federal District's Health Secretariat. Nine adolescents participated. In-depth interviews facilitated data collection, and data were analyzed with Iramuteq software and Bardin's Content Analysis. Gender identity and sexual orientation intolerance based on heteronormativity violate human rights and are relevant social determinants in health, and overcoming the psychological distress problems identified, combined with respect for human rights of the LGBT community, is an essential vector for facing adolescent health inequalities. Discrimination against LGBT adolescents is a social determinant that health services must address since its leads to harmful consequences, such as school dropouts, lack of opportunities, family bond losses, and suicidal behavior.

ABSTRACT

Objetivo: neste estudo, procura-se saber se os suplementos alimentares tão consumidos são aptos a causarem doping, já que os atletas buscam recursos ergogênicos visando à melhora da sua performance e, no campo nutricional, os suplementos aparecem como os mais consumidos. Metodologia: pesquisa bibliográfica descritiva, de abordagem exploratória; foram utilizadas informações oficiais de órgãos afetos ao controle de competições esportivas mundiais, bem como normas da Anvisa, agência reguladora brasileira. Resultados: verificou-se que a opção pelo alto consumo de suplementos alimentares se deve tanto à influência massiva da publicidade, que promete resultados miraculosos, quanto à facilidade de aquisição desses produtos. A eficácia de muitos deles carece de comprovação científica, enquanto outros podem causar efeitos colaterais graves pouco divulgados, além de conter substâncias de uso proibido e aptas a causar doping. No Brasil, a indústria de suplementos alimentares ganhou marco regulatório apenas em 2018, razão pela qual ainda não foi possível uma avaliação rigorosa dos seus efeitos. Conclusão: constatou-se que a multidisciplinariedade que envolve a relação entre dopagem e consumo de suplementos alimentares é a responsável pela dificuldade de controle do setor, reveladora ainda de quão movediça é a abordagem do problema no qual, frequentemente, se imiscuem novas áreas de conhecimento, exigindo profundo saber interdisciplinar. Daí a necessidade da interferência de profissionais habilitados para a prescrição de tais suplementos somente nos casos em que eles se mostrem necessários.


Objective: this study seeks to know if the massive consumed dietary supplements can cause doping, since, unable to accept their limits, athletes search ergogenic methods aiming for the increase of their performance and, in the nutritional field, dietary supplements appear as the most prominent choice. Methods: the present paper is a descriptive bibliographic research, with an exploratory approach, in which were used official information of organs related to the control of world sports competitions, as well as Brazilian regulatory agency rules. Results: It was found that the option for the huge consumption of dietary supplements is due to the influence of massive publicity ­ that promises miraculous results ­ and to the ease of the purchase of these products. The effectiveness of many of them lack scientific proof; many others may cause serious side effects that are not disclosed, containing substances of prohibited use and able to characterize doping. In Brazil, the sector has reached a regulation mark only in 2018, the reason why a rigorous evaluation of its effects was not possible to be done. Conclusions: it was found that the multidisciplinarity that concerns the relationship between doping and consumption of dietary supplements is responsible for the difficulty of controlling the sector, revealing how unstable is the approach to the problem, in which new areas of knowledge are often inserted, requiring deep interdisciplinary knowledge. Hence the need for the intervention of qualified professionals to prescribe such supplements only in cases where they are necessary.


Objetivo: en este estudio se busca conocer si los complementos alimenticios que se consumen ampliamente son susceptibles de provocar dopaje, ya que los deportistas buscan recursos ergogénicos con el objetivo de mejorar su rendimiento y, en el ámbito nutricional, los complementos aparecen como los más consumidos. Metodología: investigación bibliográfica descriptiva, con enfoque exploratorio; Se utilizó información oficial de agencias relacionadas con el control de las competiciones deportivas mundiales, así como normas de Anvisa, la agencia reguladora brasileña. Resultados: se encontró que la opción por un alto consumo de complementos dietéticos se debe tanto a la influencia masiva de la publicidad, que promete resultados milagrosos, como a la facilidad de compra de estos productos. La eficacia de muchos de ellos carece de pruebas científicas, mientras que otros pueden provocar efectos secundarios graves y poco conocidos, además de contener sustancias de uso prohibido y aptas para causar dopaje. En Brasil, la industria de complementos alimenticios obtuvo un marco regulatorio recién en 2018, por lo que aún no ha sido posible evaluar rigurosamente sus efectos. Conclusión: se constató que la multidisciplinariedad que implica la relación entre el dopaje y el consumo de complementos alimenticios es responsable de la dificultad para controlar el sector, revelando además lo rápido que es el abordaje del problema, en el que muchas veces se imbuyen nuevas áreas de conocimiento. lo que requiere un profundo conocimiento interdisciplinario. De ahí la necesidad de la intervención de profesionales cualificados para prescribir dichos suplementos solo en los casos en que sean necesarios.

ABSTRACT

Resumo Fundamento O fenômeno de no-reflow após a intervenção coronária percutânea está associado a um pior prognóstico em pacientes com infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST). O escore SYNTAX é um bom preditor de no-reflow. Objetivo Nosso objetivo foi avaliar se a carga aterosclerótica (escore Gensini) e a carga trombótica na artéria coronária culpada melhorariam a capacidade do escore SYNTAX para detectar o no-reflow. Métodos Neste estudo coorte prospectivo, foram estudados pacientes com IAMCSST consecutivos que se apresentaram dentro de 12 horas a partir do início dos sintomas. O no-reflow foi definido como fluxo TIMI < 3 ou fluxo TIMI =3 mas grau de blush miocárdico (myocardial blush grade) < 2. A carga trombótica foi quantificada de acordo com o grau TIMI de trombo (0 a 5). Resultados Foram incluídos 481 pacientes no estudo, com idade média de 61±11 anos. O fenômeno de no-reflow ocorreu em 32,8% dos pacientes. O escore SYNTAX (OR=1,05, IC95% 1,01-1,08, p<0,01), a carga trombótica (OR=1,17, IC95% 1,06-1,31, p<0,01), e o escore Gensini (OR=1,37, IC95% 1,13-1,65, p<0,01) foram preditores independentes do no-reflow. Os escores combinados apresentaram uma maior área sob a curva quando comparados ao escore SYNTAX isolado (0,78 [0,73-0,82] vs 0,73 [0,68-0,78], p=0,03). A análise da melhora da reclassificação líquida (NRI) categórica (0,11 [0,01-0,22], p=0,02) e contínua (NRI>0) (0,54 [0,035-0,73], p<0.001) mostrou melhora na capacidade preditiva do no-reflow no modelo combinado, com melhora da discriminação integrada (IDI) de 0,07 (0,04-0,09, p<0,001). Conclusões Nossos achados sugerem que, em pacientes com IAMCSST submetidos à intervenção coronária percutânea, a carga aterosclerótica e a carga trombótica na artéria culpada adicionam valor preditivo ao escore SYNTAX na detecção do fenômeno no-reflow.

Abstract Background No-reflow after percutaneous coronary intervention is associated with poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). SYNTAX score is a good predictor of no-reflow. Objective We aimed to evaluate whether atherosclerotic burden (Gensini score) and thrombus burden in the culprit coronary artery would improve the ability of the SYNTAX score to detect no-reflow. Methods In this prospective cohort study, consecutive patients with STEMI who presented within 12 h of onset of symptoms were selected for this study. No-reflow was defined as TIMI flow < 3 o r TIMI flow = 3 but myocardial blush grade <2. Thrombus burden was quantified according to the TIMI thrombus grade scale (0 to 5). Results A total of 481 patients were included (mean age 61±11 years). No-reflow occurred in 32.8%. SYNTAX score (OR=1.05, 95%CI 1.01-1.08, p<0.01), thrombus burden (OR=1.17, 95%CI 1.06-1.31, p<0.01), and Gensini score (OR=1.37, 95%CI 1.13-1.65, p<0.01) were independent predictors of no-reflow. Combined scores had a larger area under the curve than the SYNTAX score alone (0.78 [0.73-0.82] vs 0.73 [0.68-0.78], p=0.03). Analyses of both categorical (0.11 [0.01-0.22], p=0.02), and continuous net reclassification improvement (NRI>0) (0.54 [0.035-0.73], p<0.001) showed improvement in the predictive ability of no-reflow in the combined model, with integrated discrimination improvement (IDI) of 0.07 (0.04-0.09, p<0.001). Conclusions Our findings suggest that, in patients with STEMI undergoing percutaneous coronary intervention, atherosclerotic burden and thrombus burden in the culprit artery add predictive value to the SYNTAX score in detecting the no-reflow phenomenon.

ABSTRACT

Abstract We conducted a systematic review to compare the effectiveness and safety of exercise versus no exercise for patients with asymptomatic aortic aneurysm. We followed the guidelines set out in the Cochrane systematic review handbook. We searched Medline, Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, ICTRP, and OpenGrey using the MeSH terms "aortic aneurysm" and "exercise". 1189 references were identified. Five clinical trials were included. No exercise-related deaths or aortic ruptures occurred in these trials. Exercise did not reduce the aneurysm expansion rate at 12 weeks to 12 months (mean difference [MD], −0.05; 95% confidence interval [CI], −0.13 to 0.03). Six weeks of preoperative exercise reduced severe renal and cardiac complications (risk ratio, 0.54; 95% CI, 0.31-0.93) and the length of intensive care unit stay (MD, −1.00; 95% CI, −1.26 to −0.74). Preoperative and postoperative forward walking reduced the length of hospital stay (MD, −0.69; 95% CI, −1.24 to −0.14). The evidence was graded as 'very low' level.


Resumo Foi realizada revisão sistemática para comparar a efetividade e a segurança de exercícios versus não exercícios em pacientes assintomáticos com aneurisma de aorta. Usamos os termos MeSH aortic aneurysm e exercise para as bases MEDLINE, Embase, CENTRAL, LILACS, PeDRO, CINAHL, clinicaltrials.gov, International Clinical Trials Registry Platform (ICTRP) e OpenGrey. Foram obtidas 1.189 referências. Cinco ensaios clínicos foram incluídos. Não houve morte ou rotura associada ao exercício. Além disso, este não reduziu a velocidade de crescimento do aneurisma em 12 semanas a 12 meses [diferença de médias (DM) −0,05; intervalo de confiança de 95% (IC95%) −0,13 a 0,03]. Seis semanas de exercícios pré-operatórios reduziram complicações clínicas renais e cardíacas (razão de risco 0,54; IC95% 0,31-0,93) e a permanência em unidade de terapia intensiva (DM −1,00; IC95% −1,26 a −0,74). Caminhadas nos períodos pré e pós-operatório reduziram a permanência hospitalar. A evidência foi classificada como de muito baixa qualidade.

ABSTRACT

ABSTRACT BACKGROUND: Ultrasonography is currently used in investigating many vascular diseases, especially for guiding vascular access. OBJECTIVE: The objective here was to summarize the evidence from Cochrane systematic reviews (SRs) on the effects of ultrasound-guided vascular access as an intervention approach. DESIGN AND SETTING: Review of SRs, conducted in the Division of Vascular and Endovascular Surgery of Universidade Federal de São Paulo. METHODS: A broad search was conducted in the Cochrane Database of Systematic Reviews to retrieve any Cochrane SRs that assessed the effects of ultrasound guidance as a therapeutic approach towards performing any vascular access. The key characteristics and results of all the reviews included were summarized and discussed. RESULTS: Three SRs on venous access at all ages and one review on arterial access in pediatric participants were included. There was low to moderate certainty of evidence that ultrasound increased the success rate from the first puncture and the overall success rate of the procedure; and reduced the total rate of perioperative and postoperative adverse events, number of punctures, time needed to achieve success and rate of failure to place catheters. CONCLUSION: Evidence of low to moderate quality showed that ultrasound-guided vascular access seems to reduce the total rate of perioperative and postoperative complications/adverse effects, number of punctures, time needed to achieve success and rate of failure to perform venous catheterization in adults and arterial punctures in children. There is a lack of information regarding ultrasound-guided arterial puncture in adults. Further studies are still imperative for reaching solid conclusions, especially regarding arterial ultrasound-guided access.

ABSTRACT

SUMMARY OBJECTIVE Diabetes is one of the leading causes of cardiovascular mortality. Over the last years, mortality has decreased significantly, more in individuals with diabetes than in healthy ones. That is mostly due to the control of other cardiovascular risk factors. The objective of our study was to analyze the dyslipidemia control in two diabetes cohorts. METHODS Patients from two distinct cohorts were studied, 173 patients from the BHS (Brasília Heart Study) and 222 patients from the BDS (Brazilian Diabetes Study). The data on dyslipidemia control were studied in both different populations. All patients had diabetes. RESULTS There are significant differences concerning comorbidities between the LDL-C and BDS groups. The average glycated hemoglobin is of 8.2 in the LDL-C > 100 group in comparison with 7.7 and 7.5 in the 70-100 and < 70 groups, respectively (p = 0.024). There is a higher percentage of hypertensive patients with LDL between 70-100 (63.9%), when comparing the < 70 and > 100 groups (54.3% and 54.9%, respectively; p = 0.005). Diastolic pressure is higher in the group with LDL > 100, with an average of 87 mmHg, in comparison with 82.6 mmHg and 81.9 mmHg in the 70-100 and < 70 groups, respectively (p = 0.019). The group with LDL > 100 has the greatest percentage of smokers (8.7%) in comparison with the groups with LDL between 70-100 and < 70 (5.6% and 4.3%, respectively; p = 0.015). There is also a difference in the previous incidence of coronaropathy. In the group with LDL < 70, 28.3% of patients had already experienced a previous infarction, compared with 11.1% and 10.6% in the 70-100 and > 100 groups, respectively (p < 0.001). CONCLUSIONS The data in our study have shown that the dyslipidemia control in diabetic patients is inadequate and there is a tendency of direct association between lack of blood glucose control and lack of dyslipidemia control, in addition to the association with other cardiovascular risk factors, such as diastolic hypertension and smoking. This worsened control might be related to the plateau in the descending curve of mortality, and investments in this regard can improve the cardiovascular health in diabetic patients.


RESUMO OBJETIVO O diabetes é importante causa de mortalidade cardiovascular. Nos últimos anos, a mortalidade diminuiu substancialmente, mais em diabéticos do que em não diabéticos, em grande parte devido ao controle de outros fatores de risco cardiovasculares. Nosso estudo tem como objetivo analisar o controle de dislipidemia em duas coortes de diabéticos. MÉTODOS Foram estudados pacientes de duas coortes distintas, sendo 173 pacientes do BHS (Brasília Heart Study) e 222 pacientes do BDS (Brazilian Diabetes Study). Os dados sobre controle de dislipidemia foram estudados nas duas populações diferentes. Todos os pacientes eram diabéticos. RESULTADOS Há diferenças significativas em relação às comorbidades entre os grupos de LDL-C no BDS. A média de hemoglobina glicada é de 8,2 no grupo com LDL-C > 100, comparado com 7,7 e 7,5 nos grupos 70-100 e < 70, respectivamente (p = 0,024). Há maior porcentagem de pacientes hipertensos com LDL entre 70-100 (63,9%), quando comparado aos grupos < 70 e > 100 (54,3% e 54,9%, respectivamente; p = 0,005). A pressão diastólica é mais elevada no grupo com LDL > 100, com média de 87 mmHg, comparado com 82,6 mmHg e 81,9 mmHg nos grupos 70-100 e < 70, respectivamente (p = 0,019). O grupo com LDL > 100 tem maior porcentagem de tabagistas (8,7%) quando comparado aos grupos com LDL entre 70-100 e < 70 (5,6% e 4,3%, respectivamente; p = 0,015). Há, também, diferença na incidência prévia de coronariopatia. No grupo com LDL < 70, 28,3% dos pacientes já apresentaram infarto prévio, comparados com 11,1% e 10,6% nos grupos 70-100 e > 100, respectivamente (p < 0,001). CONCLUSÃO Os dados do nosso estudo mostram que o controle de dislipidemia em diabéticos é inadequado, e há uma tendência de associação direta entre descontrole glicêmico e descontrole de dislipidemia, além de associação com outros fatores de risco cardiovascular, como hipertensão diastólica e tabagismo. Esse pior controle pode estar relacionado ao platô no descenso da curva de mortalidade, e o investimento nesse quesito pode melhorar a saúde cardiovascular dos diabéticos.

ABSTRACT

The aim of this work was to determine the effect of homeopathic supplementation on both ovarian dynamics and conception rate in Nellore cows subjected to fixed-time artificial insemination (FTAI). Cows (n = 150) were randomly distributed to the control (CG) and the homeopathy group (HG). The HG cows were supplemented with Pró-cio in the mineral salt for 60 days and both experimental groups were further subjected to FTAI. Cows were evaluated for ovarian dynamics (n = 16), progesterone (P4) concentration (n = 16), and conception rates (n = 150). Ovarian dynamics determined by ultrasonography and showed similar findings for CG and HG, respectively. Thus follicular diameter (8.7 ± 1.0 mm vs. 10.0 ± 0.8 mm), mean pre-ovulatory follicle volume (0.46 ± 0.15 mL vs. 0.61 ± 0.12 mL), and mean follicular growth (3.65 ± 1.41 mm vs. 4.60 ± 1.21 mm) did not differ between groups. Moreover, corpus luteum diameter was similar between groups (CG: 16.28 ± 0.7 mm vs. HG: 15.6 ± 0.8 mm; P > 0.05), although P4 levels did differ (CG: 2.55 ± 0.85 ng mL-1 vs. HG: 6.52 ± 1.19 ng mL-1; P < 0.05). The conception rate after FTAI was not affected by homeopathic supplementation (CG: 74.67 %, and did HG: 77.33 %; P > 0.05). In conclusion, the homeopathic supplementation Pró-cio increases P4 concentrations but does improve the reproductive efficiency of Nellore cows subject to FTAI.


O objetivo foi determinar o efeito da suplementação homeopática na dinâmica ovariana e taxa de concepção em vacas Nelore cows submetidas à inseminação artificial em tempo fixo (IATF). As vacas (n = 150) foram distribuídas aleatoriamente nos grupos controle (GC) e grupo homeopático (GH). As vacas do GH foram suplementadas com Pró-cio® no sal mineral mineral por 60 dias. Ambos os grupos foram submetidos à IATF. As vacas foram avaliadas quanto à dinâmica ovariana (n = 16), concentração de progesterona (P4; n = 16) e taxa de concepção (n = 150). A dinâmica ovarina foi determinada por ultra-sonografia e mostrou resultados semelhantes para o GC e o GH, respectivamente. Portanto, para diâmetro folicular (8,7 ± 1,0 mm vs. 10,0 ± 0,8 mm), volume médio do folículo pré-ovulatório (0,46 ± 0,15 mL vs. 0,61 ± 0,12 mL) e crescimento folicular médio (3,65 ± 1,41 mm vs. 4,60 ± 1,21 mm) não diferiram entre os grupos. Além disso, o diâmetro do corpo lúteo foi semelhante entre os grupos (CG: 16,28 ± 0,7 mm vs. HG: 15,6 ± 0,8 mm; P > 0.05), apesar dos níveis de P4 diferirem (CG: 2,55 ± 0,85 ng mL-1 vs. GH: 6,52 ± 1,19 ng mL-1; P < 0.05). A taxa de concepção após a IATF não foi afetada pela suplementação homeopática (GC:74.67 % vs. GH: 77.33 %; P > 0.05). Em conclusão, a suplementação homeopática com Pró-cio aumenta a concentração de P4 mas não melhora a eficiência reprodutiva de vacas Nelore cows submetidas à IATF.

ABSTRACT

Abstract The More Doctors Program (PMM) has three axes of action and is grounded on the pedagogical guidelines of Permanent Education. Considering the Program's scope, which ranges from the emergency supply of doctors to the expansion of the number of seats in undergraduate and medical residency courses, its management is interministerial, as the Ministry of Health and the Ministry of Education share responsibilities for its full operation. This article reports on the construction of the Ministry of Education's experience of managing PMM, which includes the structuring of a new Directorate and new ways of doing management in this Ministry. It also points out the main difficulties and facilities throughout the process, and reflects on the perspectives and challenges for the Program's continuity and sustainability.(AU)

ABSTRACT

ABSTRACT BACKGROUND: Varicose veins affect nearly 30% of the world's population. This condition is a social problem and needs interventions to improve quality of life and reduce risks. Recently, new and less invasive methods for varicose vein treatment have emerged. There is a need to define the best treatment options and to reduce the risks and costs. Since there are cosmetic implications, treatments for which effectiveness remains unproven present risks to consumers and higher costs for stakeholders. These risks and costs justify conducting an overview of systematic reviews to summarize the evidence. DESIGN AND SETTING: Overview of systematic reviews within the Discipline of Evidence-Based Health, at Universidade Federal de São Paulo (UNIFESP). METHODS: Systematic reviews on clinical or surgical treatments for varicose veins were included, with no restrictions on language or publication date. RESULTS: 51 reviews fulfilled the inclusion criteria. Outcomes and comparators were described, and a narrative review was conducted. Overall, there was no evidence that compression stockings should be recommended for patients as the initial treatment or after surgical interventions. There was low to moderate evidence that minimally invasive therapies (endovenous laser therapy, radiofrequency ablation or foam sclerotherapy) are as safe and effective as conventional surgery (ligation and stripping). Among these systematic reviews, only 18 were judged to present high quality. CONCLUSIONS: There was evidence of low to moderate quality that minimally invasive treatments, including foam sclerotherapy, laser and radiofrequency therapy are comparable to conventional surgery, regarding effectiveness and safety for treatment of varicose veins.

ABSTRACT

ABSTRACT BACKGROUND: The timing of surgery for recently symptomatic carotid artery stenosis remains controversial. Early cerebral revascularization may prevent a disabling or fatal ischemic recurrence, but it may also increase the risk of hemorrhagic transformation, or of dislodging a thrombus. This review examined the randomized controlled evidence that addressed whether the increased risk of recurrent events outweighed the increased benefit of an earlier intervention. OBJECTIVES: To assess the risks and benefits of performing very early cerebral revascularization (within two days) compared with delayed treatment (after two days) for people with recently symptomatic carotid artery stenosis. METHODS: Search methods: We searched the Cochrane Stroke Group Trials Register in January 2016, the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library 2016, issue 1), MEDLINE (1948 to 26 January 2016), EMBASE (1974 to 26 January 2016), LILACS (1982 to 26 January 2016), and trial registers (from inception to 26 January 2016). We also handsearched conference proceedings and journals, and searched reference lists. There were no language restrictions. We contacted colleagues and pharmaceutical companies to identify further studies and unpublished trials Selection criteria: All completed, truly randomized trials (RCT) that compared very early cerebral revascularization (within two days) with delayed treatment (after two days) for people with recently symptomatic carotid artery stenosis. Data collection and analysis: We independently selected trials for inclusion according to the above criteria, assessed risk of bias for each trial, and performed data extraction. We utilized an intention-to-treat analysis strategy. MAIN RESULTS: We identified one RCT that involved 40 participants, and addressed the timing of surgery for people with recently symptomatic carotid artery stenosis. It compared very early surgery with surgery performed after 14 days of the last symptomatic event. The overall quality of the evidence was very low, due to the small number of participants from only one trial, and missing outcome data. We found no statistically significant difference between the effects of very early or delayed surgery in reducing the combined risk of stroke and death within 30 days of surgery (risk ratio (RR) 3.32; confidence interval (CI) 0.38 to 29.23; very low-quality evidence), or the combined risk of perioperative death and stroke (RR 0.47; CI 0.14 to 1.58; very low-quality evidence). To date, no results are available to confirm the optimal timing for surgery. AUTHORS CONCLUSIONS: There is currently no high-quality evidence available to support either very early or delayed cerebral revascularization after a recent ischemic stroke. Hence, further randomized trials to identify which patients should undergo very urgent revascularization are needed. Future studies should stratify participants by age group, sex, grade of ischemia, and degree of stenosis. Currently, there is one ongoing RCT that is examining the timing of cerebral revascularization.

ABSTRACT

Resumo Contexto As cardiopatias podem causar alterações no formato das ondas da ultrassonografia vascular (UV) em vasos periféricos. Essas alterações, tipicamente bilaterais e sistêmicas, são pouco conhecidas e estudadas. Objetivo Avaliar as ondas periféricas da UV de pacientes idosos para identificar alterações decorrentes de cardiopatias. Métodos Foram estudados 183 pacientes idosos submetidos a UV periférica no ano de 2014. Resultados Foram avaliados 102 mulheres (55,7%) e 81 homens (44,3%) com idade entre 60 e 91 anos (média de 70,4±7,2 anos). Encontraram-se alterações pela UV em 84 pacientes (45,9%). Foram identificadas 138 alterações de oito dos 13 tipos descritos na literatura: arritmia, onda bisferiens de pico sistólico, baixa velocidade de pico sistólico, pulsatilidade em veias femorais, bradicardia, taquicardia, onda de pulso parvus tardus e onda de pulso alternans. Houve baixa concordância entre a presença e a não presença de alterações na UV e na avaliação cardiológica. Na análise específica das alterações, os exames tiveram uma concordância variável, que foi boa para o achado de taquicardia, moderada para arritmia e baixa para bradicardia. Não houve concordância entre a UV e os exames cardiológicos para as demais alterações. Conclusões É possível identificar determinadas alterações cardíacas em idosos por meio da análise do formato das ondas periféricas da UV. É importante reconhecer e relatar a presença dessas alterações, pela possibilidade de alertar para um diagnóstico ainda não identificado nesses pacientes. Entretanto, mais estudos são necessários para que seja definida a importância das alterações no formato das ondas Doppler periféricas no reconhecimento de cardiopatias.


Abstract Background Heart diseases can cause changes to vascular ultrasonography (VUS) waveforms in peripheral vessels. These changes are typically bilateral and systemic, they have been little studied, and little is known about them. Objective To assess peripheral VUS waveforms in elderly patients in order to identify changes caused by heart diseases. Methods During 2014, a total of 183 elderly patients were examined with peripheral VUS and the results were analyzed. Results The sample comprised 102 women (55.7%) and 81 men (44.3%) with ages ranging from 60 to 91 years (mean of 70.4±7.2 years). Abnormalities were identified in VUS waveforms in 84 patients (45.9%). A total of 138 abnormalities were identified and classified into eight of the 13 categories described in the literature, as follows: arrhythmia, systolic pulsus bisferiens, low peak systolic velocity, pulsatile flow in femoral veins, bradycardia, tachycardia, pulsus tardus et parvus and pulsus alternans. There was low agreement between presence/absence of VUS abnormalities and cardiological assessments. Analysis of specific abnormalities revealed variable levels of agreement between VUS and cardiological assessments, ranging from good for tachycardia, moderate for arrhythmia, to low for bradycardia. There was no agreement between VUS and cardiological examinations for the remaining categories of abnormalities. Conclusions Certain cardiac abnormalities can be identified in elderly patients by analysis of peripheral VUS waveforms. It is important to recognize and report the presence of these abnormalities because there is a possibility that they may serve to signal hitherto unidentified diagnoses in these patients. However, further studies are needed to determine the importance of changes to peripheral Doppler waveforms to recognition of heart diseases.

ABSTRACT

A trombose venosa é a principal complicação da microcirurgia vascular e a intervenção precoce é necessária para o salvamento dos retalhos, com índices de sucesso de apenas 50% das revisões cirúrgicas; trombose da microcirculação, produção de radicais livres de oxigênio (RLO) e edema são os elementos principais da lesão de isquemia/reperfusão (I/R), e o planejamento das terapias protetoras tem como objetivo amenizar estas alterações. Os fármacos antioxidantes, antiagregantes plaquetários e anticoagulantes são utilizados no controle da lesão de I/R em diferentes órgãos. Neste estudo, em modelo de amputação subtotal de membro posterior de rato submetido a isquemia global primária, foi testado o efeito protetor dos fármacos alopurinol, heparina, tirofiban ou vitamina C durante a isquemia secundaria pós congestão venosa. Foram operados 100 ratos, que apos isquemia global de 90 minutos, foram divididos em cinco grupos de 20 animais recebendo uma das respectivas drogas na veia femoral contra-lateral: 1ml de solução fisiológica 0,9% no grupo controle (GC), 1ml de alopurinol 45mg/kg no grupo experimental 1 (G1), 1ml de heparina 200UI/kg no grupo experimental 2 (G2), 1ml de tirofiban 50 ug /ml no grupo experimental 3 (G3) e 1 ml de vitamina C 100mg/kg no grupo experimental 4 (G4); o clampe foi então retirado do feixe vascular e se iniciou a reperfusão de 60 minutos; a colocação do clampe vascular apenas na veia femoral direita iniciou a congestão venosa (isquemia secundária) do membro por 90 minutos seguido de outra reperfusão de 60 minutos; O músculo gastrocnêmio foi dissecado e retirado para analise histológica e os animais sacrificados por injeção letal. Foram estudados a porcentagem de viabilidade celular muscular, o edema e o extravasamento de hemácias. A porcentagem de lesão celular do músculo do grupo controle foi 54,6% (±10,6), do G1 31,5% (±13,6), do G2 24,7% (±11,7), do G3 24,6% (±8,6) e do G4 21,3% (±8,6). Os grupos foram comparados por modelo de comparação...


Venous thrombosis is the main complication of vascular microsurgery an early intervention is mandatory to rescue the flap, with a success rate of only 50% of surgical revisions; microcirculation thrombosis, oxygen free radicals production and edema are the main elements of ischemia/reperfusion (I/R) injury, and protective therapies aim to mitigate these changes. Antioxidants, antiplatelets and anticoagulants are used in different organs to control this injury. In this study, in a partial hind limb amputation model submitted to global ischemia, it was tested the protective effect of Allopurinol, Heparin, Tirofiban or Vitamin C during secondary ischemia after venous congestion. A hundred rats divided in five groups of 20 animals each were operated; after global ischemia of 90 minutes each group was injected into the contra lateral femoral vein one of the following solutions: 1 ml of saline solution NaCl 0,9% - control group (CG); 1ml of Allopurinol 45mg/kg - experimental group 1 (G1); 1ml of Heparin 200 UI/kg - experimental group 2 (G2); 1ml of Tirofiban 50 ug /ml - experimental group 3 (G3); 1ml of Vitamin C 100mg/kg - experimental group 4 (G4). Sixty minutes of limb reperfusion was performed, and a secondary period of limb ischemia started with the clamping of the femoral vein only (limb congestion) which lasted for 90 minutes (secondary ischemia). After that, the vein clamp was removed and a 60 minute reperfusion period was observed; at the end of the second reperfusion period, the right gastrocnemius muscle was removed and fixed in 10% formaldehyde, animals were euthanized with a lethal dose of Pentobarbital. Muscle fibers were scored as uninjured or injured based on the morphology of individual fibers; interstitial edema and bleeding were graded on a four-point scale. The control group had more damaged muscle cells 54.6±10.6% when compared to allopurinol 31.5±13,6%, heparin 24.7±11.7%, tirofiban 24.6±8.6% and Vitamin C 21.3±8.6%...

ABSTRACT

Deformidades e anormalidades em crustáceos têm sido associadas a fatores genéticos, problemas ocorridos durante a muda, danos causados por ectobiontes, predadores ou estresse ambiental causado por produtos químicos. Espécimes de caranguejos coletados no litoral de São Paulo apresentaram anormalidades no corpo. Estes caranguejos pertencem às seguintes espécies: Callinectes ornatus (Ordway, 1863), Arenaeus cribrarius (Lamarck, 1818) e Leurocyclus tuberculosus (H. Milne Edwards & Lucas, 1843). As coletas foram realizadas por meio de arrastos camaroneiros em julho de 2008, agosto e outubro de 2009, na região de Ubatuba, Estado de São Paulo, Brasil. As anormalidades apresentadas no corpo dos caranguejos encontravam-se no dáctilo do quelípodo (C. ornatus macho adulto), defeitos na carapaça (A. cribrarius macho adulto) e alterações abdominais (C. ornatus fêmea adulta; L. tuberculosus macho adulto e fêmea ovígera). O registro de tais ocorrências pode servir na distinção de alterações causadas naturalmente ou por impacto humano, podendo fornecer ferramentas úteis no sentido de monitorar áreas ambientais não protegidas, bem como trazer subsídios ao entendimento de alterações não usuais ocorridas durante a ontogenia de espécies importantes para a comunidade bentônica.


Deformities and abnormalities in crustaceans have been associated to genetic problem, which occurred during molt process, damage caused by ectobionts, predators or environmental stress caused by chemical wastes. Some crab specimens collected in the São Paulo littoral were found having body abnormalities. They belong to the following crab species: Callinectes ornatus (Ordway, 1863), Arenaeus cribrarius (Lamarck, 1818) and Leurocyclus tuberculosus (H. Milne Edwards; Lucas, 1843). Samplings were performed by trawling during July 2008, August and October 2009 at the Ubatuba region, São Paulo State, Brazil. Body abnormalities were verified in the cheliped dactyl (C. ornatus an adult male), carapace deformities (A. cribrarius an adult male) and abdominal alterations (C. ornatus an adult female; L. tuberculosus an adult male and an ovigerous female). The record and analysis of such occurrences can help in the distinction of natural or human impact caused alterations. In this way, the occurrence study of this kind of body alterations could provide tools in order to control unprotected environmental areas, as well as bring subsides to understand the unusual variations during the ontogeny of important species in the benthic community.
