RESUMEN

Detecting determinism and nonlinear properties from empirical time series is highly nontrivial. Traditionally, nonlinear time series analysis is based on an error-prone phase space reconstruction that is only applicable for stationary, largely noise-free data from a low-dimensional system and requires the nontrivial adjustment of various parameters. We present a data-driven index based on Fourier phases that detects determinism at a well-defined significance level, without using Fourier transform surrogate data. It extracts nonlinear features, is robust to noise, provides time-frequency resolution by a double running window approach, and potentially distinguishes regular and chaotic dynamics. We test this method on data derived from dynamical models as well as on real-world data, namely, intracranial recordings of an epileptic patient and a series of density related variations of sediments of a paleolake in Tlaxcala, Mexico.

RESUMEN

Purpose: Injectable hyaluronic acid-based fillers are commonly used for the correction of skin contour irregularities and to smooth skin depressions formed by volume loss during the aging process. These fillers are particularly efficient to restore perioral skin depressions/wrinkles or to correct topographical anomalies. The European directives require a continuous evaluation of the performance of these medical devices, particularly for CE marked products. Methods: An 18-month prospective randomized single-blind study for the efficacy and safety of ART FILLER Universal (AFU) was performed on the lips, the nasolabial folds, and the marionettes lines. The evaluations were performed on 153 subjects enrolled in this study. The efficacy, the longevity, and the safety were evaluated for the injected areas via area specific clinical scoring after a single injection with the filler and with no re-touch. Results: We showed here that filler injection induced potent improvements of volume restoration after a single injection on all the treated areas. These beneficial properties of the filler were significant 3 weeks after injection and during the whole study period. Moreover, injections of the filler were well tolerated by the subjects. The recorded adverse events are routinely seen with HA fillers for face volume corrections, and most of these local reactions resolved within 14 days. Conclusion: AFU was well tolerated and showed a continuous efficacy for at least 18 months, in exploratory analyses.

RESUMEN

BACKGROUND: Age-related changes of facial soft tissue cause clinical signs of facial aging such as lip atrophy, marionette lines, and an accentuated nasolabial fold. These changes can be modified using dermal fillers. AIMS: To evaluate efficacy, longevity, and safety of a cross-linked hyaluronic acid-based filler with Tri-Hyal technology in the treatment of lips, nasolabial folds, and marionette lines. MATERIALS AND METHODS: This prospective, multi-center trial evaluated injections of three different areas (lips, nasolabial fold alone, or with marionette wrinkles) with a soft tissue filler containing 25 mg/ml cross-linked hyaluronic acid and 0.3% lidocaine. Primary endpoint was the aesthetic correction 3 weeks after one injection session without touch-up. Follow-up was 18 months. Assessments were performed using the Global Aesthetic Score (GAS), clinical scoring based on photographic scales, high-frequency ultrasound imaging, and the Global Aesthetic Improvement Scale (GAIS). RESULTS: In total, 100 subjects were injected. GAS improved significantly for all treatment indications at 3 weeks (p < 0.0001). Success rates were highest for nasolabial folds (98.4%), followed by marionette lines (94.4%) and lips (73.5%). After 18 months post-injection, success was observed in 91%, 88%, and 33% of subjects injected into nasolabial folds, marionette lines, and lips, respectively. GAIS scored highest for nasolabial folds (SGAIS: 71%; IGAIS: 40%), followed by marionette lines (SGAIS: 56%; IGAIS: 33%) and lips (SGAIS: 30%; IGAIS: 22%) at 18 months follow-up. CONCLUSIONS: The filler demonstrated high efficacy and safety in all indications. Regional differences in longevity were evident. Thus, the necessity of regional retreatments should be discussed with patients before injection.

RESUMEN

Introduction: some plants such as turmeric, cinnamon, and okra are known to have therapeutic functions such as antioxidant and anti-inflammatory activity. Furthermore, an immunomodulatory role has been observed in the production of antibodies, in particular immunoglobulin A (IgA), which mediates a variety of protective functions for the organism. Objective: the aim of the present study was to investigate the effect of dietary plants on the production of IgA in healthy Wistar rats. Methods: thus, 48 male Wistar rats of 90 days of age were allocated to four groups. The animals were treated for 14 days with dried turmeric, cinnamon, or okra (50, 50, 12.5 mg/day, respectively) in phosphate buffered saline, or with only phosphate buffered saline by gavage. The animals received water and feed ad libitum. Body mass and relative weight ofperitoneal fat, adrenal gland, kidney, spleen, liver and thymus, biochemical parameters, and IgA levels were analyzed. Results: no significant changes were observed in the body mass, relative weight of organs and tissues, and biochemical parameters. An increase in serum IgA levels was observed in animals treated with turmeric or cinnamon. Conclusion: we conclude that the treatment with turmeric and cinnamon increased IgA production. Therefore, our study supports the idea that dietary supplementation with these plants may improve humoral immunity.


Introdução: algumas plantas como a cúrcuma, a canela e o quiabo são conhecidas por apresentar funções terapêuticas, como atividade antioxidante e anti-inflamatória. Além disso, tem sido observado um papel imunomodulador sobre a produção de anticorpos, em especial a imunoglobulina A (IgA), a qual medeia uma variedade de funções protetoras para o organismo. Objetivo: o objetivo do presente estudo foi investigar o efeito de plantas dietéticas na produção de IgA em ratos Wistar saudáveis. Métodos: destarte, 48 ratos machos Wistar com 90 dias de idade foram alocados em quatro grupos. Os animais foram tratados por 14 dias com cúrcuma seca, canela ou quiabo (50, 50, 12,5 mg/dia, respectivamente) em solução salina tamponada com fosfato ou apenas solução salina tamponada com fosfato, por gavagem. Os animais receberam água e ração ad libitum. Foram analisados a massa corporal e o peso relativo da gordura peritoneal, glândula adrenal, rim, baço, fígado e timo, parâmetros bioquímicos e níveis de IgA. Resultados: não foram observadas alterações significativas na massa corporal, no peso relativo dos órgãos e tecidos e nos parâmetros bioquímicos. Foi observado aumento dos níveis séricos de IgA nos animais tratados com cúrcuma ou canela. Conclusão: podemos concluir que o tratamento com cúrcuma e canela aumentou a produção de IgA. Portanto, nosso estudo suporta a ideia de que a suplementação alimentar com essas plantas pode melhorar a imunidade humoral.

RESUMEN

BACKGROUND: Greater trochanteric pain syndrome (GTPS) is a debilitating chronic condition, most prevalent in postmenopausal women. A positive association between high estrogen levels and tendon health may exist, and postmenopausal women have reduced estrogen. Menopausal hormone therapy (MHT) may reduce the incidence of tendon abnormality, particularly when combined with exercise. PURPOSE: To determine the effect of MHT and exercise on tendon pain and function in postmenopausal women with GTPS. STUDY DESIGN: Randomized controlled clinical trial; Level of evidence, 1. METHODS: Postmenopausal women (N = 132; n = 12, lost to follow-up) with GTPS were randomized into MHT and placebo transdermal cream groups combined with tendon-specific or sham exercise. All groups received education about avoiding gluteal tendon compression and load management throughout 12 weeks of intervention. The primary outcome was the Victorian Institute of Sport Assessment for gluteal tendinopathy (VISA-G), and secondary outcomes were measured at baseline and at 12 and 52 weeks. The Global Rating of Change was assessed at 12 and 52 weeks. A linear mixed-effects model was used to assess differences. Body mass index (BMI) was included as a covariate. RESULTS: All participant groups improved over time (baseline vs 12 weeks, P < .001; baseline vs 52 weeks, P < .001). There was no difference among exercise groups measured by all outcomes (VISA-G: baseline, P = .97, mean difference [MD] = 0.10; 12 weeks, P = .49, MD = 2.15; 52 weeks, P = .32, MD = -3.08). There was a significant interaction effect between cream and BMI; therefore, the population was stratified by BMI levels (<25, <30, ≥30). The MHT groups (with exercise and education) had significantly better VISA-G outcomes (baseline, P = .04, MD = -11.20, 95% CI = -21.70 to -0.70; 12 weeks, P < .001, MD = -20.72, 95% CI = -31.22 to -10.22; 52 weeks, P = .002, MD = -16.71, 95% CI = -27.21 to -6.22) and secondary measure scores as compared with placebo at all time points when BMI was <25. CONCLUSION: MHT or placebo combined with tendon-specific or sham exercise plus education reduced pain and increased function for this population. For women with a BMI <25, MHT with any exercise plus education was better than placebo. A targeted exercise or sham exercise strategy is effective when prescribed with education about avoiding gluteal tendon compression and load management.

RESUMEN

Abstract Angiotensin-converting enzyme inhibitors (ACEi) are used to reduce blood pressure and vascular resistance by modulating the ACE activity responsible for the angiotensin II formation. However, different ACEi seem to influence exercise-induced angiogenesis. The objective of this review was to investigate the effects of different ACEi on vessel growth in skeletal muscle induced by exercise training. The present study is characterized by a narrative literature review design, the databases of Scielo, Google Scholar and PubMed were consulted. There are different groups of ACEi , sulfhydryl group such as captopril and a carboxyl group such as perindiporil and enalapril that can influence their effects on ACE activity. It is already known that exercise promotes the increase of vessels from vessels already existing in the skeletal musculature, a process known as angiogenesis and contributes to the blood pressure reduction (BP). Although these different responses are still scarce, vessel endothelial growth factor (VEFG) and nitric oxide (NO) may participate. Thus, the use of different ACEi can influences the angiogenesis responses induced by exercise, being one of the important mechanisms for BP reduction. The choice of ACEi group should be carefully analyzed for hypertensive individuals who practice physical exercise. (AU)


Resumo Os inibidores da enzima conversora de angiotensina (iECA) são utilizados para redução da pressão arterial e resistência vascular modulando a atividade da ECA responsável pela formação da angiotensina II. Entretanto, diferentes iECAs parecem influenciar a angiogênese induzida pelo exercício físico. Desta maneira objetivo desta revisão foi investigar os efeitos de diferentes iECA sobre o crescimento de vasos no musculo esquelético induzido pelo exercício físico. O presente estudo caracteriza-se um delineamento de revisão de literatura narrativa, foram consultadas as bases de dados do Scielo, Google acadêmico e PubMed. Existem grupos distintos dos iECAs, grupo sulfidrila como o captopril e o grupo carboxila como o perindiporil e grupo que pode influenciar seus efeitos sobre a atividade da ECA. Já é sabido que O exrcício promove o aumento de vasos a partir de vasos já existentes na musculatura esquelética, processo conhecido como angiogênese e colabora para redução da pressão arterial (PA). Entretanto os iECAs parecem influenciar esta resposta do aumento da densidade capilar no músculo esquelético. Embora ainda sejam escassos estas diferentes respostas podem ter as participações do fator de crescimento endotelial de vasos (VEFG) e o óxido nítrico (NO). Desta maneira o uso dos grupos do iECAs podem influenciar as resposta da angiogênese induzido pelo exercício sendo um dos mecanismos importantes pela redução da PA. A escolha do grupo de iECA deve ser analisada com cautela para indivíduoS hipertensos que praticam exercício físico. (AU)

RESUMEN

Consent and discernment are two important notions, constantly present in the daily life of psychiatric caregivers. The Haute Autorité de santé sheds valuable light on discernment by defining it in terms of five characteristics. As for consent, it is based on the fundamental principle of an agreement given on a proposal with a perception of the stakes by the different parties. The consequences within the multidisciplinary team are multiple, between the information recorded in the shared medical record, the care decisions according to the clinic and the impact on the patients' group. These are all serious ethical and practical difficulties.

RESUMEN

Climacteric is a natural process characterized by the female hormones reduction and increased symptoms that interfere in the woman's quality of life. The objective was to raise scientific evidence on the physical exercise effects as a therapeutic strategy on climacteric symptoms. This systematic review study accessed the Virtual Health Library (VHL) and consulted articles from the last 10 years, with the following eligibility criteria; inclusion, scientific articles published in the last 10 years, with clinical, quasi-experimental, cross-sectional design and case studies conducted with women in the climacteric. Articles published before 2010 with delineations were excluded; epidemiological, systematic review, meta-analyzes, experimental studies with animal model. The studies included in the review were read in full, critically analyzed and categorized. The findings showed that active women have a reduction in vasomotor and somatic symptoms of the climacteric, also collaborating in the prevention of diseases prevalent in this period. Aerobic physical exercise improves physical fitness and quality of life indicators of climacteric women. In clinical practice, aerobic exercise can be considered an auxiliary strategy in the climacteric symptoms treatment and female health improvement. (AU)

RESUMEN

Objective: To analyze the association between social isolation (SI), physical activity level (PAL) and sedentary behavior in the university community in pandemic times. Methods: A cross-sectional epidemiological study was carried out from May 7 to June 4, 2020, with 194 participants linked to the Federal University of Jataí Universidade Federal de Jataí ­ UFJ), in Goiás, Brazil. Data were collected using a form created on Google Forms® and sent to the email addresses of the academic community of UFJ to assess socioeconomic characteristics, lifestyle, body composition, physical activity level, and sedentary behavior, taking into account the periods prior to and during SI. Data were analyzed using descriptive and inferential statistics, with p<0.05 considered significant. Results: The study participants were predominantly women (n=141; 72.6%), 18-27 years old (n=100; 71%), single(n=96; 68%), students (n=110; 78%), and had no pre-existing diseases (n=94; 67%). Increases in the body mass and body massindex (BMI) (p<0.05) were observed during SI, and physical activity downtime increased for all participants, regardless of sex(p<0.05). Conclusion: SI recommended by health managers due to the pandemic caused by COVID-19 was responsible for inducing an increase in body mass and BMI accompanied by an increase in screen time during the week, as well as a decrease in the PAL of individuals belonging to the community of university students of UFJ. Descriptors: Coronavirus Infections; Sedentary Behavior; Motor Activity.


Objetivo: Analisar a associação de isolamento social (IS), nível de atividade física (NAF) e comportamento sedentário na comunidade universitária em tempos pandêmicos. Métodos: Estudo epidemiológico transversal realizado no período de 7 de maio a 4 de junho de 2020 com 194 participantes vinculados à Universidade Federal de Jataí (UFJ), Goiás, Brasil. Para coleta de dados, foi enviado ao e-mail da comunidade acadêmica da UFJ um formulário criado no Google Forms® para avaliar as características socioeconômicas, os hábitos de vida, a composição corporal, o nível de atividade física e o comportamento sedentário, levando em consideração o período anterior e durante o IS. Os dados foram analisados por estatística descritiva e inferencial, com p<0,05. Resultados: Os participantes do estudo foram, predominantemente, mulheres (n=141; 72,6%), na faixa etária de 18-27 anos (n=100; 71%), solteiras (n=96; 68%), discentes (n=110; 78%), com ausência de doenças pré-existentes(n=94; 67%). Durante o IS ocorreu aumento da massa corporal e do índice de massa corporal (IMC) dos indivíduos (p<0,05). Além disso, o tempo de inatividade física aumentou para todos os indivíduos, independente do sexo (p<0,05). Conclusão: O IS proporcionado pelos gestores de saúde em decorrência da pandemia ocasionada pela COVID-19 foi responsável por induzir um aumento da massa corporal e do IMC, acompanhado pela elevação do tempo de tela durante a semana e a diminuição do NAF dos indivíduos pertencentes à comunidade universitária da UFJ.

RESUMEN

BACKGROUND: The objective of this study was to explore the usefulness of virtual models and three-dimensional (3D) printing technologies for planning complex non-congenital cardiovascular surgery. METHODS: Between July 2018 and December 2019, adult patients with different cardiovascular structural diseases were included in a clinical protocol to explore the usefulness of Standard Tessellation Language (STL)-based virtual models and 3D printing for prospectively planning surgery. A qualitative descriptive analysis from the surgeon's viewpoint was done based on the characteristics, advantages and usefulness of 3D models for guiding, planning and simulating the surgical procedures. RESULTS: A total of 14 custom 3D-printed heart and great vessel replicas with their corresponding 3D virtual models were created for preoperative surgical planning. Six of 14 models helped to redefine the surgical approach, 3 were useful to verify device delivery, while the rest did not change the surgical decision. In all open surgery cases, cardiac and vascular anatomy accuracy of virtual and physical 3D replicas was validated by direct visualisation of the organs during surgery. Printing was achieved through an external provider associated with the Hospital, who printed the final prototype in 5-7 days. Printed production cost was between 100 and 500 USD per model. CONCLUSIONS: In the current study, the selected 3D printed models presented different advantages (visual, tactile, and instrumental) over the traditional flat anatomical images when simulating and planning some complex types of surgery. Notwithstanding 3D printing advantages, STL-based virtual models were pre-printing useful tools when instrumentation on a physical replica was not required.

RESUMEN

BACKGROUND: Long-term benefit of carotid endarectomy has not yet been fully investigated in average volume centers. Thus our purpose is to evaluate long-term results of carotid endarterectomies at a medium-volume hospital. METHODS: A retrospective analysis of carotid artery stenosis operated between 2008 and 2017 in a community hospital was done. Demographic and postoperative outcomes were evaluated in short and long-term by Kaplan-Meier survival analysis. RESULTS: 167 procedures in 159 patients were included. Average age was 72 years, and 65% were men. Twenty-nine percent of the patients were symptomatic and the rest asymptomatic. Median hospitalization was 3 (IQR 3-4) days and the mean follow-up was 56 months. No hospital mortality was recorded. At 120-month follow-up, freedom of stroke was 97.4%, death 97.3%, restenosis, 98.7% and all combined events 92.9% (log rank p = .042) Combined event-free survival was 84.4% in symptomatic patients, and 96.1% in asymptomatic patients (log rank p = .025). CONCLUSIONS: In a medium-volume hospital combined event-free survival was 84.4% in symptomatic patients and 96.1% in asymptomatic at a 10-year follow-up.

RESUMEN

Complete surgical resection of soft-tissue sarcomas (STSs) frequently requires complex multivisceral resections, which is the most important factor related to overall survival and local recurrence. Major vascular involvement is not rare in patients with primary retroperitoneal STSs. We present a 54-year-old woman with a retroperitoneal STS encasing the infrarenal abdominal aorta. The patient underwent complete oncological resection with vascular reconstruction using a bi-iliac vascular graft. Major blood vessel involvement is not a contraindication for STS surgery with a curative intent.

RESUMEN

RESUMEN Introducción: En relación con la cirugía coronaria, existen discrepancias respecto del pronóstico y tratamiento de la enfermedad cardiovascular en la mujer entre distintos estudios internacionales. Objetivo: Analizar los resultados de mortalidad y complicaciones hospitalarias y a 60 días luego de la cirugía de revascularización miocárdica aislada o combinada, en forma comparativa entre mujeres y varones. Material y métodos: Se analizaron en forma retrospectiva los resultados hospitalarios y a 60 días de la cirugía de revascularización coronaria aislada o combinada de acuerdo con el sexo, operados entre 2011 y 2017. Se compararon las variables perioperatorias, la mortalidad esperada con el EuroSCORE II y la mortalidad observada por toda causa. Se realizó un análisis de propensión para equiparar las poblaciones de mujeres y varones. Resultados: De 1670 cirugías de revascularización coronaria aisladas o combinadas, el 27,4% (n: 457) eran mujeres; y, de 1305 cirugías aisladas, el 14,2% (n: 185) eran mujeres. La mortalidad en las mujeres a 30 y 60 días fue del 2,7% y del 4,3% vs. el 2,1% (RR = 1,26 IC95% 0,49-3,26, p = 0,632) y el 2,3% (RR = 1,86 IC95% 0,86-4,05, p = 0,113, potencia 53%) en los varones. Tras el análisis de propensión de los pacientes sometidos a cirugía coronaria asilada, la mortalidad a 60 días en las mujeres fue del 4,0% vs. 2,3% en los varones (RR = 1,75 IC95% 0,52-5,87, p = 0,359). Conclusiones: En comparación con los varones, las mujeres sometidas a cirugía de revascularización coronaria tuvieron más edad y mayor riesgo esperado por el EuroSCORE II, peor función renal tanto para la cirugía coronaria combinada como aislada. La mortalidad luego de la cirugía de revascularización coronaria aislada o combinada fue mayor en mujeres que en hombres a 60 días e, incluso, esta diferencia se mantuvo después de ajustar por confundidores.


ABSTRACT Background: The outcome and treatment of cardiovascular disease in women differ among international studies. Objective: The aim of this study was to compare in-hospital mortality and complications with mortality and complications at 60 days following isolated or combined coronary artery bypass graft surgery between women and men. Methods: The outcomes during hospitalization and at 60 days following isolated or combined coronary artery bypass graft surgery procedures performed between 2011 and 2017 were retrospectively analyzed. Perioperative variables, expected all-cause mortality estimated by EuroSCORE II and observed all-cause mortality were compared. A propensity score analysis was performed to match female and male populations. Results: Of the 1670 isolated or combined coronary artery bypass graft procedures, 27.4% (n=457) were performed in women, and 185 (14.2%) of 1305 isolated surgeries corresponded to women. Mortality in women at 30 and 60 days was 2.7% and 4.3%. respectively, vs. 2.1% (RR: 1.26; 95% CI, 0.49-3.26; p=0.632) and 2.3% (RR: 1.86; 95% CI, 0.86-4.05, p=0.113, power 53%), respectively, in men. After analyzing the propensity score of patients undergoing isolated revascularization procedures, 60-day mortality in women was 4.0% vs. 2.3% in men (RR: 1.75; 95% CI; 0.52-5.87, p=0.359). Conclusions: Compared with men, women undergoing isolated or combined coronary artery bypass graft surgery were older and had higher expected risk calculated by EuroSCORE II and worse renal function. Mortality after isolated or combined coronary artery bypass graft surgery was higher in women than in men at 60 days, and this difference remained even after adjusting for confounders.

RESUMEN

The challenge in the search for relationships between urban space, physical mobility, and health status, is detecting indicators able to link the environment with healthy life habits. Therefore, the objective was to design an urban index for the identification of urban environment propensity for physical activity (PA) and to determine how it relates to lifestyle and anthropometric parametrization of obesity. Participants (N = 318-60.4% women and 39.6% men) were recruited from a mid-sized city with epidemiology and morbidity rates below the average for the mid-west region of Brazil. Body mass index (BMI) was measured and a questionnaire was applied to gather information about PA and life habits. The spatial urban health index (SUHI) was designed in a geographic information system using data from demographic, environmental and urban physical features. The relationship between BMI and PA was verified with multiple linear regression, controlled for SUHI levels. Regarding the BMI of the population, 69.5% were classified in the eutrophic or overweight ranges, with no effect of gender and age. The SUHI classified 63.7% of the urban area favorable to PA. The PA routine was adequate (≥3 sessions with ≥1 h each) for ~80% of the population, as well as healthy habits such as non smoking (~94%) and non alcohol abuse (~55%). The SUHI strengthens the relationships of BMI to weekly frequency (r = -0.68; t = -9.4; p<0.001) and session duration (r = -0.66; t = -2.8; p<0.001) for the whole group by improving the explanatory coefficient in ~25% (R2Adj = 0.61 to R2Adj = 0.85). The SUHI indicated that the urban environment is able to promote healthy life habits by diminishing the "obesogenic" features of the city when physical structures are planned to facilitate PA, whatever the gender and age group.

RESUMEN

RESUMEN Introducción: Los resultados del seguimiento a largo plazo constituyen uno de los mejores parámetros para evaluar la calidad de una intervención médica. Objetivos: Analizar la supervivencia global y la supervivencia libre de eventos cardiovasculares a 20 años de la cirugía coronaria en un hospital de comunidad con historia clínica electrónica de larga data. Métodos: Se estudiaron en forma retrospectiva los resultados alejados de las cirugías coronarias aisladas efectuadas en pacientes con enfermedad de múltiples vasos o tronco de coronaria izquierda entre 1999 y 2003 en un hospital de comunidad. El seguimiento hasta 20 años se realizó a través de la historia clínica electrónica. Resultados: Se logró un tiempo de seguimiento medio de 125 meses (rango: 6-268) en 254 pacientes de los 272 operados en ese período (93,4%). El número promedio de puentes fue 3,3 (desvío estándar: 0,97); en 97,6% se usó al menos una arteria mamaria y 59,4% recibieron un puente con arteria radial. Se obtuvo un seguimiento de 2646 pacientes-años, con un riesgo anual de muerte por toda causa de 2,5%. La supervivencia global al seguimiento medio fue de 0,806 (error estándar, EE: 0,03), y la supervivencia libre de eventos cardiovasculares fue de 0,826 (EE: 0,03). Conclusiones: El registro electrónico completo de los afiliados a un hospital de comunidad operados hace más de 15 años permitió analizar la supervivencia global y libre de eventos a largo plazo. Estos resultados servirán como estándar al momento de elegir entre la cirugía y la angioplastia de múltiples vasos.


ABSTRACT Background: The outcomes of long-term follow-up constitute one of the best parameters to assess the quality of a medical intervention. Objectives: To analyze the overall and the free-of-cardiovascular events 20-year survival after coronary surgery in a community hospital with a long-standing electronic medical records. Methods: The results of coronary surgeries in patients with multi-vessel or trunk disease operated between 1999 and 2003 in a community hospital were retrospectively studied. The follow-up up to 20 years was carried out through the electronic medical record. Results: Of 272 patients operated, a mean follow-up of 125 months (range 6-268) was achieved in 254 (93.4%). The average number of bypasses was 3.3 (standard deviation 0.97); in 97.6%, at least one internal mammary artery was used and 59.4% received a radial artery graft. A follow-up of 2646 patient-years was obtained with an annual risk of death from all causes of 2.5%. The overall survival at the mean follow-up time was 0.806 (standard error (SE) 0.03), and the cardiovascular event-free survival 0.826 (SE 0.03). Conclusions: The complete electronic registration of affiliates to a community hospital operated more than 15 years ago allowed us to analyze the overall survival and the freedom of long-term events. These results will serve as a standard when choosing between surgery and multi-vessel angioplasty.

RESUMEN

The literature presents some studies that show that aerobic exercise is responsible for mediating muscle catabolism. Thus, it is interpreted that continuous aerobic exercise produces little or no increase in muscle hypertrophy. The purpose of this review was to demonstrate the effects of aerobic training on muscle hypertrophy alone or in conjunction with resistance training. The present study is characterized by a review of the narrative literature, the databases of SciELO, Google academic and PubMed were consulted. Many studies show that aerobic training (AT) can promote hypertrophic responses in untrained individuals, however, these responses are related to exercise variables such as intensity, volume, frequency, and modality. Higher, continuous or interval intensities, at least 80% of the HRR, seem to be capable of promoting hypertrophic responses when compared to low intensities. In addition, the training volume may also influence this response and different modalities may have a distinct response to muscle hypertrophy. While the combination of TA and resistance training (TR) corresponds to concurrent training (CT), the literature demonstrates that AT in CT can negatively affect acute and chronic hypertrophic responses depending on intensity, volume, mode and training schedule.

A literatura apresenta alguns estudos que mostram que exercício aeróbio é responsável por mediar o catabolismo muscular. Dessa maneira, interpreta-se que o exercício contínuo aeróbio produz pouco ou nenhum aumento na hipertrofia muscular. O objetivo desta revisão foi demonstrar os efeitos do treinamento aeróbio sobre a hipertrofia muscular de forma isolada ou em conjunto com o treinamento resistido. O presente estudo caracteriza-se um delineamento de revisão de literatura narrativa, foram consultadas as bases de dados do SciELO, Google acadêmico e PubMed. Muitos estudos mostram que o treinamento aeróbio (TA) pode promover respostas hipertróficas em indivíduos não treinados, entretanto, estas respostas estão relacionadas às variáveis do exercícios como intensidade, volume, frequência e modalidade. Intensidades mais altas, contínuas ou intervaladas, no mínimo 80% da FCR, parecem ser capazes de promover respostas hipertróficas quando comparado a baixas intensidades. Além disso, o volume do treinamento também pode influenciar esta resposta e diferentes modalidades podem ter resposta distinta sobre a hipertrofia muscular. Enquanto a combinação do TA com o treinamento resistido (TR) corresponde ao treinamento concorrente (TC), a literatura demonstra que o TA no TC pode interferir negativamente nas respostas hipertróficas de maneira aguda e crônica dependendo da intensidade, volume, modalidade e programação de treinamento.

RESUMEN

Los aneurismas del cayado aórtico representan un desafío, ya que el involucramiento de sus grandes ramas exige una técnica quirúrgica compleja. A partir de la aparición del tratamiento endovascular, una alternativa desarrollada en los últimos años para abordar el cayado aórtico consistió en el tratamiento híbrido de esta patología, mediante la derivación quirúrgica de los vasos del cuello y la posterior exclusión del aneurisma con una endoprótesis. Este método híbrido es conocido con el nombre de debranching, y en forma simplificada consiste en realizar, sin circulación extracorpórea, una serie de puentes entre la aorta ascendente y el tronco braquiocefálico, la arteria carótida izquierda y eventualmente la arteria subclavia izquierda, para permitir avanzar una endoprótesis que cubra toda la luz del aneurisma. Se describe la técnica quirúrgica del debranching híbrido tipo I, sin el auxilio de la circulación extracorpórea e implante anterógrado de la endoprótesis, para los aneurismas del cayado aórtico.


Aortic arch aneurysms represent a major challenge as the involvement of the supra-aortic vessels demands a complex surgical technique. Since the advent of endovascular aortic repair, hybrid treatment of aortic arch disease has emerged in recent years. The procedure consists of surgical bypass of the supra-aortic vessels followed by exclusion of the aneurysm with an endograft. This hybrid method is known as debranching and, briefly, consists in performing bypasses between the ascending aorta and the brachiocephalic artery, the left carotid artery and possibly the left subclavian artery without cardiopulmonary bypass, in order to advance an endograft to cover the entire lumen of the aneurysm. The aim of this paper is to describe the surgical technique of type I hybrid debranching without cardiopulmonary bypass and antegrade endograft delivery to treat aortic arch aneurysms.
