ABSTRACT

A testosterona, hormônio masculino com efeitos androgênicos e anabólicos, também exerce efeito sobre o leito vascular. Este hormônio promove vasodilatação através da liberação de óxido nítrico e modulação dos canais de cálcio que impacta a função endotelial. Em pacientes com doença arterial coronariana (DAC) e insuficiência cardíaca (IC), reduções nas concentrações de testosterona total (<300 ng/dL) estão relacionadas com maior mortalidade e severidade dessas doenças. Em pacientes com DAC, a reposição de testosterona (RT) tem relação com melhora do tônus vascular coronário e melhora do limiar de isquemia. Em pacientes com IC, os efeitos parecem estar mais relacionados à melhora da capacidade funcional, aumento na distância percorrida em testes funcionais, maior VO2máx, menor razão VE/VCO2, e melhora adicional da sensibilidade barorreflexa. No entanto, embora os efeitos da testosterona sobre o aumento de massa muscular e força muscular estejam bem estabelecidos na literatura, os efeitos dessa substância no sistema cardiovascular precisam ser elucidados. O aumento das concentrações de antígeno prostático específico da próstata tem sido constantemente discutido quando a RT é proposta no tratamento de pacientes com doenças cardiovasculares. Por se tratar de um hormônio com grande potencial anabólico, os efeitos do uso de quantidades suprafisiológicas de testosterona e seus análogos sobre as alterações cardiovasculares em jovens atletas têm sido estudados. Portanto, o objetivo dessa revisão é abordar os efeitos benéficos da RT em homens com hipogonadismo com DAC e IC, e mostrar os riscos relacionados com a prática indiscriminada do uso de anabolizantes em jovens sem deficiência de testosterona


Testosterone, the male hormone with androgenic and anabolic effects, also has an effect on the vascular bed. This hormone promotes vasodilation by releasing nitric oxide and calcium channel modulation that impacts endothelial function. In patients with coronary artery disease (CAD) and heart failure (HF), reductions in total testosterone concentrations (<300 ng/dL) are related to higher mortality and severity of these diseases. In patients with CAD, testosterone replacement (TR) is related to improved coronary vascular tone and improved ischemia threshold. In HF patients, the effects seem be more related to improved functional capacity, increased distance covered in functional tests, higher VO2max, lower LV/VCO2 ratio, and further improvement of baroreflex sensitivity. However, although the effects of testosterone on muscle mass gain and muscle strength are well established in the literature, the effects of testosterone on the cardiovascular system need to be elucidated. Increased prostate-specific prostate antigen concentrations have been constantly discussed when TR is proposed in the treatment of patients with cardiovascular disease. Because it is a hormone with great anabolic potential, the effects of supraphysiological amounts of testosterone and its analogues on cardiovascular disorders in young athletes have been studied. Therefore, the objective of this review is to address the beneficial effects of TR in men with hypogonadism with CAD and HF, and to show the risks related to anabolic steroids abuse in young people without testosterone deficiency

ABSTRACT

Abstract Background: Resting sympathetic hyperactivity and impaired parasympathetic reactivation after exercise have been described in patients with heart failure (HF). However, the association of these autonomic changes in patients with HF and sarcopenia is unknown. Objective: The aim of this study was to evaluate the impact of autonomic modulation on sarcopenia in male patients with HF. Methods: We enrolled 116 male patients with HF and left ventricular ejection fraction < 40%. All patients underwent a maximal cardiopulmonary exercise testing. Maximal heart rate was recorded and delta heart rate recovery (∆HRR) was assessed at 1st and 2nd minutes after exercise. Muscle sympathetic nerve activity (MSNA) was recorded by microneurography. Dual-energy X-ray absorptiometry was used to measure body composition and sarcopenia was defined by the sum of appendicular lean muscle mass (ALM) divided by height in meters squared and handgrip strength. Results: Sarcopenia was identified in 33 patients (28%). Patients with sarcopenia had higher MSNA than those without (47 [41-52] vs. 40 [34-48] bursts/min, p = 0.028). Sarcopenic patients showed lower ∆HRR at 1st (15 [10-21] vs. 22 [16-30] beats/min, p < 0.001) and 2nd min (25 [19-39] vs. 35 [24-48] beats/min, p = 0.017) than non-sarcopenic. There was a positive correlation between ALM and ∆HRR at 1st (r = 0.26, p = 0.008) and 2nd min (r = 0.25, p = 0.012). We observed a negative correlation between ALM and MSNA (r = -0.29, p = 0.003). Conclusion: Sympatho-vagal imbalance seems to be associated with sarcopenia in male patients with HF. These results highlight the importance of a therapeutic approach in patients with muscle wasting and increased peripheral sympathetic outflow.


Resumo Fundamento: Hiperatividade simpática de repouso e uma reativação parassimpática diminuída pós-exercício têm sido descritas em pacientes com insuficiência cardíaca (IC). No entanto, a associação dessas alterações autonômicas em pacientes com IC sarcopênicos ainda não são conhecidas. Objetivo: O objetivo deste estudo foi avaliar o impacto da modulação autonômica sobre sarcopenia em pacientes com IC do sexo masculino. Métodos: Foram estudados 116 pacientes com IC e fração de ejeção ventricular esquerda inferior a 40%. Todos os pacientes foram submetidos ao teste de exercício cardiopulmonar máximo. A frequência cardíaca máxima foi registrada, e o delta de recuperação da frequência cardíaca (∆RFC) foi avaliado no primeiro e no segundo minuto após o exercício. A atividade nervosa simpática muscular (ANSM) foi registrada por microneurografia. A Absorciometria Radiológica de Dupla Energia foi usada para medir composição cpororal, e a sarcopenia definida como a soma da massa muscular apendicular (MMA) dividida pela altura em metros ao quadrado e força da mão. Resultados: A sarcopenia foi identificada em 33 pacientes (28%). Os pacientes com sarcopenia apresentaram maior ANSM que aqueles sem sarcopenia - 47 (41-52) vs. 40 (34-48) impulsos (bursts)/min, p = 0,028). Pacientes sarcopênicos apresentaram ∆RFC mais baixo no primeiro [15 (10-21) vs. 22 (16-30) batimentos/min, p < 0,001) e no segundo [25 (19-39) vs. 35 (24-48) batimentos/min, p = 0,017) minuto que pacientes não sarcopênicos. Observou-se uma correlação positiva entre a MMA e a ANSM (r = -0,29; p = 0,003). Conclusão: Um desequilíbrio simpático-vagal parece estar associado com sarcopenia em pacientes com IC do sexo masculino. Esses resultados destacam a importância de uma abordagem terapêutica em pacientes com perda muscular e fluxo simpático periférico aumentado.

ABSTRACT

Background:Testosterone deficiency in patients with heart failure (HF) is associated with decreased exercise capacity and mortality; however, its impact on hospital readmission rate is uncertain. Furthermore, the relationship between testosterone deficiency and sympathetic activation is unknown.Objective:We investigated the role of testosterone level on hospital readmission and mortality rates as well as sympathetic nerve activity in patients with HF.Methods:Total testosterone (TT) and free testosterone (FT) were measured in 110 hospitalized male patients with a left ventricular ejection fraction < 45% and New York Heart Association classification IV. The patients were placed into low testosterone (LT; n = 66) and normal testosterone (NT; n = 44) groups. Hypogonadism was defined as TT < 300 ng/dL and FT < 131 pmol/L. Muscle sympathetic nerve activity (MSNA) was recorded by microneurography in a subpopulation of 27 patients.Results:Length of hospital stay was longer in the LT group compared to in the NT group (37 ± 4 vs. 25 ± 4 days; p = 0.008). Similarly, the cumulative hazard of readmission within 1 year was greater in the LT group compared to in the NT group (44% vs. 22%, p = 0.001). In the single-predictor analysis, TT (hazard ratio [HR], 2.77; 95% confidence interval [CI], 1.58–4.85; p = 0.02) predicted hospital readmission within 90 days. In addition, TT (HR, 4.65; 95% CI, 2.67–8.10; p = 0.009) and readmission within 90 days (HR, 3.27; 95% CI, 1.23–8.69; p = 0.02) predicted increased mortality. Neurohumoral activation, as estimated by MSNA, was significantly higher in the LT group compared to in the NT group (65 ± 3 vs. 51 ± 4 bursts/100 heart beats; p < 0.001).Conclusion:These results support the concept that LT is an independent risk factor for hospital readmission within 90 days and increased mortality in patients with HF. Furthermore, increased MSNA was observed in patients with LT.


Fundamento:A deficiência de testosterona na insuficiência cardíaca (IC) está associada à diminuição da capacidade de exercício e mortalidade, mas o seu impacto sobre as readmissões é incerto. Além disso, sua relação com a ativação simpática é desconhecida.Objetivo:O presente estudo investigou o papel dos níveis de testosterona nas reinternações hospitalares, na mortalidade e na atividade nervosa simpática em pacientes com IC.Métodos:A testosterona total (TT) e a testosterona livre (TL) foram medidas em 110 pacientes do sexo masculino hospitalizados, com fração de ejeção < 45% eclassificação funcional da New York Heart Association (NYHA) IV, qualificados em dois grupos: 66 com baixos níveis de testosterona (BT) e 44 com testosterona normal (TN). Hipogonadismo foi definido como TT < 300 ng/dL e TL < 131 pmol/L. A atividade nervosa simpática muscular (ANSM) foi gravada por microneurografia em uma subpopulação de 27 pacientes.Resultados:O tempo de permanência hospitalar foi maior em pacientes BT em comparação com pacientes TN (37 ± 4 vs. 25 ± 4 dias; p = 0,008). Da mesma forma, o risco cumulativo de readmissão no período de um ano foi maior em pacientes BT (44% vs. 22%, p = 0,001). Na análise de uma única variável preditora, a testosterona total (HR = 2,77, IC 95% 1,58-4,85, p = 0,02) previu readmissão hospitalar no prazo de 90 dias. Na análise de uma única variável preditora, testosterona total (HR = 4,65, IC 95% 2,67-8,10, p = 0,009) e readmissão dentro de 90 dias (HR = 3,27, IC 95% 1,23-8,69, p = 0,02) previram aumento de mortalidade. Ativação neuro-humoral, estimada pela ANSM, foi significativamente maior nos pacientes BT em comparação aos do grupo TN (65 ± 3 vs. 51 ± 4 disparos/100BC; p < 0,001).Conclusão:Estes resultados sustentam o conceito de que BT é um fator de risco independente para a readmissão hospitalar dentro de 90 dias e para aumento de mortalidade em pacientes com IC. Além disso, observou-se aumento da ANSM em pacientes com baixos níveis de testosterona.

ABSTRACT

This paper studies the impact of HIV/AIDS on per capita income and education. It explores two channels on how HIV/AIDS affects income that have not been sufficiently stressed by previous literature: the reduction of the incentives to stay in school due to shorter expected longevity and the reduction in productivity of experienced workers. In the model, individuals live for three periods, may get infected in the second period, and with some probability die of AIDS before reaching the third period of their lives. Parents care for the welfare of the future generations so that they will maximize lifetime utility of their dynasty. The simulations predict that the most affected countries in Sub-Saharan Africa in the future will be, on average, 30% poorer than they would be without AIDS. Schooling will decline in some cases by 40%. These figures are dramatically reduced with widespread medical treatment, as it increases the survival probability and productivity of infected individuals.

ABSTRACT

A lesão de células granulares congênitas ou epúlide congênita é uma lesão rara, que acomete recém-nascidos (RN) e ocorre predominantemente no rebordo alveolar superior. Essa lesão apresenta comportamento benigno, e não há relatos na literatura de recidiva. Nós descrevemos o caso de uma RN de ciinco dias de vida, apresentando lesão na mucosa gengival mandibular com dificuldades para alimentação. O tratamento realizado constou de uma excisão cirúrgica sob anestesia geral, e o exame histológico mostrou presença de células granulares.


Congenital granular cell lesion, or congenital epulis, is a rare lesion occurring in the newborn and arising predominantly from the maxillary alveolar ridge. It presents a bening behavior and no cases of recurrence have been reported. We report the case of a girl aged five days, who presented with a large mass arising in the gengival mucosa of the mandible, causing difficulty in feeding. The treatment was a surgical excision under general anesthesia and histological examination revealed large granular cells.

ABSTRACT

Macroglossia é uma doença de etiologia múltipla, classificada como verdadeira ou relativa, podendo ser congênita ou adquirida. A redução cirúrgica da língua é um procedimento incomum, indicado para correção de alterações funcionais ou estéticas. Pode estar associada à mordida aberta anterior, à protrusão bimaxilar e à instabilidade no tratamento ortodôntico e ortodôntico-cirúrgico. Neste artigo, são descritos dois casos de deformidade dentofacial e má oclusão classe III de Angle associada à macroglossia relativa, submetidos à cirurgia ortognática e glossectomia parcial.


Congenital or acquired macroglossia - the abnormal enlargement of the tongue - is a pathological condition of multiple etiology, and may be classified as acquired or congenital. Surgical reduction of the tongue is an uncommon procedure that, however, may be required for functional and aesthetic reasons. Enlarged tongue is thought to be an etiological factor in anterior open bite, bimaxillary protrusion, and instability after orthodontic and orthodontic-cum-surgical treatment. This article describes two patients with dentofacial deformities and Angle Class III malocclusion associated with relative macroglossia, treated with orthognathic surgery and partial glossectomy.
