ABSTRACT

RESUMO O objetivo deste trabalho foi comparar o pico de torque e flexibilidade dos membros inferiores de indivíduos com e sem diabetes mellitus tipo 2 (DM2). O método foi o estudo com grupos expostos e não expostos ao DM2. Foram incluídos indivíduos com diagnóstico médico de DM2, encaminhados para eletroneuromiografia, e não expostos ao DM2. Foram excluídos da pesquisa indivíduos com idade superior a 70 anos ou que, por algum motivo, não conseguiram realizar um ou dois dos testes. A amostra foi não probabilística, composta por 64 indivíduos: 34 (53,1%) expostos ao DM2 e 30 não expostos; 50 (78,1%) eram do sexo feminino, a idade média era de 60,7±7,1 anos, e o membro inferior dominante era o direito em 57 (89,1%) dos indivíduos. Comparando indivíduos com e sem diagnóstico de DM2, observou-se redução do torque de flexão à esquerda, em velocidade angular de 120° (25,94±2,26 vs. 33,79±2,4nm, p=0,027, respectivamente). Relatou-se menor valor do torque de dorsiflexão à direita, em velocidade angular de 60°, dos diabéticos em relação aos não diabéticos (10,95±0,89 vs. 13,95±0,96nm, p=0,033, respectivamente). Ao comparar indivíduos com DM2, com e sem diagnóstico de neuropatia diabética periférica (NDP), notou-se maior déficit de flexão entre os indivíduos neuropatas em comparação com não neuropatas (46,57±9,47 vs. 11,63±13,85nm, p=0,049, respectivamente). Não foram encontradas diferenças estatisticamente significativas ao comparar os grupos de expostos e não expostos ao DM2 e diabéticos neuropatas e não neuropatas.


RESUMEN El objetivo de este trabajo fue comparar el pico de torque y la flexibilidad de los miembros inferiores de individuos con y sin diabetes mellitus tipo 2 (DM2). El método fue el estudio con grupos expuestos y no expuestos al DM2. Se incluyeron individuos con diagnóstico médico de DM2, encaminados para electroneuromiografía, y no expuestos al DM2. Se excluyeron de la investigación a individuos mayores de 70 años o que, por algún motivo, no pudieron realizar una o dos de las pruebas. La muestra fue no probabilística, compuesta por 64 individuos: 34 (53,1%) expuestos al DM2 y 30 no expuestos; 50 (78,1%) eran de sexo femenino, la edad media era de 60,7±7,1 años, y el miembro inferior dominante era el derecho en 57 (89,1%) de los individuos. En comparación con individuos con y sin diagnóstico de DM2, se observó reducción del torque de flexión a la izquierda, en velocidad angular de 120° (25,94±2,26 frente a 33,79±2,4nm, p=0,027, respectivamente). Se ha reportado un menor valor del torque de dorsiflexión a la derecha, en velocidad angular de 60°, de los diabéticos con relación a los no diabéticos (10,95±0,89 frente a 13,95±0,96nm, p=0,033, respectivamente). Al comparar individuos con DM2, con y sin diagnóstico de neuropatía diabética periférica (NDP), se notó mayor déficit de flexión entre los individuos neuropáticos en comparación con no neuropáticos (46,57±9,47 vs. 11,63±13,85nm, p=0,049, respectivamente). No se encontraron diferencias estadísticamente significativas al comparar los grupos de expuestos y no expuestos al DM2 y los diabéticos neuropáticos y no neuropáticos.


ABSTRACT To compare the muscle strength and flexibility of the lower limbs of individuals with and without T2DM. The method was a study of the types exposed and unexposed to T2DM. Individuals diagnosed with T2DM, individuals referred to electromyography, and those unexposed to T2DM were included. The exclusion criteria were: individuals over 70 years old; those who for some reason failed to complete one or both tests. The study population consisted of 64 individuals; 34 (53.1%) exposed to DM and 30 unexposed, 50 (78.1%) were female, the mean age was 60.7±7.1 and the dominant lower limb was right in 57 (89.1%) individuals. Comparing individuals with and without a diagnosis of DM, one observed a reduction in the flexion torque on the left at a 120 ° angular velocity in diabetics individuals compared with nondiabetic patients, 25.94±2.26 vs 33.79±2, 4nm, p=0.027, respectively. The reduction in dorsiflexion torque on the right, at a 60 ° angular velocity was observed in diabetics compared with nondiabetic patients, 10.95±0.89 vs. 13.95±0.96nm, p=0.033, respectively. When comparing diabetic individuals with and without a diagnosis of PDN, one observed a greater flexion deficit among neuropathic individuals when compared with non-neuropathic individuals, 46.57±9.47 vs 11.63±13.85nm, p=0.049, respectively. No statistically significant differences were found when comparing groups exposed and unexposed to T2DM, and neuropathic and non-neuropathic diabetics.

ABSTRACT

The purpose of this study was to look at the determinants of the unsteady walking (UW) symptom in patients with type 2 diabetes mellitus (T2DM) by defining if UW and/or the Diabetic Neuropathy Symptoms Score (DNSS) are associated with positive scores in Beck's Depression Inventory (BDI) and with a positive Michigan Neuropathy Screening Instrument score (MNSI). We evaluated 203 T2DM patients without visible gait disturbances. They were divided into UW (+) and UW (−) or DNSS (+) and DNSS (−) according to symptoms. We found a prevalence of 48.3% for UW (+) and of 63% for DNSS (+) in our sample. In univariate analysis, the presence of UW was significantly associated with waist circumference (P=0.024), number of comorbidities (P=0.012), not practicing physical exercise (P=0.011), positive BDI score (P=0.003), presence of neuropathic symptoms by the MNSI questionnaire (P<0.001), and positive diabetic neuropathy screening by MNSI (P=0.021). In multivariate analysis, UW (used as a dependent variable) was independently associated with a positive BDI score (P<0.001; 95%CI=1.01-1.03), T2DM duration (P=0.023; 95%CI=1.00-1.03), number of co-morbidities (P=0.032; 95%CI=1.01-1.37), and a sedentary lifestyle (P=0.025; 95%CI=1.06-2.5). The UW symptom and a positive DNSS are more closely related to a positive score for depression than to presence of neuropathy in T2DM.

ABSTRACT

Abstract Background: Heart rate variability (HRV) indices may detect autonomic changes with good diagnostic accuracy. Type diabetes mellitus (DM) individuals may have changes in autonomic modulation; however, studies of this nature in this population are still scarce. Objective: To compare HRV indices between and assess their prognostic value by measurements of sensitivity, specificity and predictive values in young individuals with type 1 DM and healthy volunteers. Methods: In this cross-sectional study, physical and clinical assessment was performed in 39 young patients with type 1 DM and 43 young healthy controls. For HRV analysis, beat-to-beat heart rate variability was measured in dorsal decubitus, using a Polar S810i heart rate monitor, for 30 minutes. The following indices were calculated: SDNN, RMSSD, PNN50, TINN, RRTri, LF ms2, HF ms2, LF un, HF un, LF/HF, SD1, SD2, SD1/SD2, and ApEn. Results: Type 1 DM subjects showed a decrease in sympathetic and parasympathetic activities, and overall variability of autonomic nervous system. The RMSSD, SDNN, PNN50, LF ms2, HF ms2, RRTri, SD1 and SD2 indices showed greater diagnostic accuracy in discriminating diabetic from healthy individuals. Conclusion: Type 1 DM individuals have changes in autonomic modulation. The SDNN, RMSSD, PNN50, RRtri, LF ms2, HF ms2, SD1 and SD2 indices may be alternative tools to discriminate individuals with type 1 DM.


Resumo Fundamento: Alguns índices da variabilidade da frequência cardíaca (VFC) podem ser capazes de detectar alterações autonômicas com boa acurácia diagnóstica. Indivíduos com Diabetes Mellitus (DM) tipo 1 podem apresentar alterações na modulação autonômica, contudo, estudos dessa natureza são incipientes nesses sujeitos. Objetivo: Comparar diferentes índices da VFC e avaliar seu valor prognóstico por medidas da sensibilidade, especificidade e valores preditivos em jovens com DM tipo 1 e jovens controles saudáveis. Métodos: Neste estudo transversal, foram realizadas avaliações físicas e clínicas em 39 jovens com DM tipo 1 e 43 jovens saudáveis. Para análise da VFC, a frequência cardíaca foi captada batimento a batimento usando um monitor de frequência acardíaca, PolarS810i, por 30 minutos com os voluntários em decúbito dorsal. Foram calculados os índices: SDNN, RMSSD, PNN50, TINN, RRTri, LF ms2, HF ms2, LF un, HF um, LF/HF, SD1, SD2, SD1/SD2, ApEn. Resultados: Indivíduos com DM tipo 1 apresentam redução na atividade simpática, parassimpática e na variabilidade global do sistema nervoso autônomo. Índices RMSSD, SDNN, PNN50, LF ms2, HF ms2, RRTri, SD1 e SD2 representam melhor acurácia diagnóstica para discriminar indivíduos diabéticos de saudáveis. Conclusão: Indivíduos com DM tipo 1 apresentam alterações na modulação autonômica e os índices SDNN, RMSSD, PNN50, RRtri, LF ms2, HF ms2, SD1 e SD2 podem ser uma opção utilizada para discriminar indivíduos com DM tipo 1.

ABSTRACT

A nefropatia diabética consiste na principal causa de doença renal terminal e está associada a um risco aumentado de doença cardiovascular. O estudo dos mecanismos responsáveis pelo desenvolvimento da nefropatia diabética possui extrema importância, já que pode contribuir para o desenvolvimento de terapias mais eficazes para a prevenção e o tratamento dessa complicação. Alguns estudos têm demonstrado que os processos inflamatórios devem desempenhar um papel significativo no desenvolvimento e na progressão da nefropatia diabética. Citocinas inflamatórias, como interleucina 1, fator de necrose tumoral alfa e interleucina 6, têm sido associadas com o desenvolvimento e a evolução da disfunção renal em pacientes diabéticos tipos 1 e 2. O reconhecimento das citocinas inflamatórias como fatores patogênicos significativos da nefropatia diabética pode fornecer novos alvos terapêuticos. Neste contexto, o uso de anti-inflamatórios para o tratamento da doença renal no diabetes tem se mostrado estratégia bastante promissora


Diabetic nephropathy is the most important cause of endstage renal disease, and is associated with an increased risk of cardiovascular disease. The study of the mechanisms involved with the development of diabetic nephropathy is extremely relevant, since it can contribute to the development of more effective therapies for the prevention and treatment of this complication. Some studies have demonstrated that the inflammatory processes play a significant role in the development and progression of diabetic nephropathy. Inflammatory cytokines, such as interleukin-1, tumor necrosis factor alpha and interleukin-6, have been associated with the development and evolution of renal dysfunction in type 1 and type 2 diabetic patients. The recognition of inflammatory cytokines as significant pathogenic factors of diabetic nephropathy can provide new therapeutic targets. In this context, the use of antiinflammatories for the treatment of renal disease in diabetes has been shown to be a very promising strategy

ABSTRACT

Background:Diabetes affects approximately 250 million people in the world. Cardiovascular autonomic neuropathy is a common complication of diabetes that leads to severe postural hypotension, exercise intolerance, and increased incidence of silent myocardial infarction.Objective:To determine the variability of heart rate (HR) and systolic blood pressure (SBP) in recently diagnosed diabetic patients.Methods:The study included 30 patients with a diagnosis of type 2 diabetes of less than 2 years and 30 healthy controls. We used a Finapres® device to measure during five minutes beat-to-beat HR and blood pressure in three experimental conditions: supine position, standing position, and rhythmic breathing at 0.1 Hz. The results were analyzed in the time and frequency domains.Results:In the HR analysis, statistically significant differences were found in the time domain, specifically on short-term values such as standard deviation of NN intervals (SDNN), root mean square of successive differences (RMSSD), and number of pairs of successive NNs that differ by more than 50 ms (pNN50). In the BP analysis, there were no significant differences, but there was a sympathetic dominance in all three conditions. The baroreflex sensitivity (BRS) decreased in patients with early diabetes compared with healthy subjects during the standing maneuver.Conclusions:There is a decrease in HR variability in patients with early type 2 diabetes. No changes were observed in the BP analysis in the supine position, but there were changes in BRS with the standing maneuver, probably due to sympathetic hyperactivity.


Fundamento:O diabetes afeta aproximadamente 250 milhões de pessoas no mundo. A neuropatia autonômica cardiovascular é uma complicação comum do diabetes que leva à hipotensão postural grave, intolerância ao exercício e aumento na incidência de infarto do miocárdio silencioso.Objetivo:Determinar a variabilidade da frequência cardíaca (FC) e da pressão arterial sistólica (PAS) em pacientes diabéticos com diagnóstico recente.Métodos:O estudo incluiu 30 pacientes com diabetes tipo 2 diagnosticado há menos de 2 anos e 30 controles saudáveis. Nós utilizamos o dispositivo Finapres® para medir durante cinco minutos a FC batimento-a-batimento e a pressão arterial (PA) em três condições experimentais: posição supina, em pé e durante respiração rítmica na frequência de 0,1 Hz. Os resultados foram analisados nos domínios do tempo e da frequência.Resultados:Em relação à FC, foram encontradas diferenças estatisticamente significativas nos valores da análise do domínio do tempo, especificamente em valores determinados a curto prazo, tais como o desvio-padrão dos intervalos NN (DPNN), a raiz quadrada da média das diferenças sucessivas (RQMDS) para a FC e o número de pares de NNs sucessivos que diferem em mais de 50 ms (pNN50). Não houve diferença significativa na análise da PA, mas houve uma dominância simpática nas três condições. A sensibilidade do barorreflexo (SBR) esteve diminuída em pacientes com diabetes de início recente, em comparação aos indivíduos saudáveis durante execução da manobra na posição ortostática.Conclusões:Há uma diminuição na variabilidade da FC em pacientes com diabetes tipo 2 de início recente. Não foram observadas alterações na análise da PA na posição supina, mas a SBR apresentou mudança com a manobra em pé provavelmente causada por hiperatividade simpática.

ABSTRACT

Introduction: Although diuretics are mainly used for the treatment of acute decompensated heart failure (ADHF), inadequate responses and complications have led to the use of extracorporeal ultrafiltration (UF) as an alternative strategy for reducing volume overloads in patients with ADHF. Objective: The aim of our study is to perform meta-analysis of the results obtained from studies on extracorporeal venous ultrafiltration and compare them with those of standard diuretic treatment for overload volume reduction in acute decompensated heart failure. Methods: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases were systematically searched using a pre‑specified criterion. Pooled estimates of outcomes after 48 h (weight change, serum creatinine level, and all-cause mortality) were computed using random effect models. Pooled weighted mean differences were calculated for weight loss and change in creatinine level, whereas a pooled risk ratio was used for the analysis of binary all-cause mortality outcome. Results: A total of nine studies, involving 613 patients, met the eligibility criteria. The mean weight loss in patients who underwent UF therapy was 1.78 kg [95% Confidence Interval (CI): −2.65 to −0.91 kg; p < 0.001) more than those who received standard diuretic therapy. The post-intervention creatinine level, however, was not significantly different (mean change = −0.25 mg/dL; 95% CI: −0.56 to 0.06 mg/dL; p = 0.112). The risk of all-cause mortality persisted in patients treated with UF compared with patients treated with standard diuretics (Pooled RR = 1.00; 95% CI: 0.64–1.56; p = 0.993). Conclusion: Compared with standard diuretic therapy, UF treatment for overload volume reduction in individuals suffering from ADHF, resulted in significant reduction of body weight within 48 h. However, no significant decrease of serum creatinine level or reduction of all-cause mortality ...


Introdução: Embora os diuréticos sejam utilizados como o principal tratamento na insuficiência cardíaca aguda descompensada, sua significativa taxa de complicações e respostas inadequadas levou ao uso de ultrafiltração extracorpórea como uma alternativa. Objetivo: Realizar uma meta-análise de estudos de ultrafiltração venosa extracorpórea e diuréticos no tratamento de sobrecarga hídrica na insuficiência cardíaca aguda descompensada. Métodos: MEDLINE, EMBASE e o banco de dados do Cochrane Central Register of Controlled Trials foram pesquisados sistematicamente usando um critério pré-estabelecido. Estimativas combinadas para os resultados na alteração de peso em 48 horas, creatinina sérica e mortalidade por todas as causas foram calculados utilizando modelos de efeitos aleatórios. As diferenças entre as médias ponderadas combinadas foram calculadas para a perda de peso e alteração nos níveis de creatinina e relação risco partilhado foi utilizada para o resultado binário de todas as causas de mortalidade. Resultados: Nove estudos foram considerados elegíveis para a análise, com inclusão de 613 pacientes. Pacientes submetidos a ultrafiltração perderam em média 1,78kg (intervalo de confiança [IC] 95% -2,65 a 0,91kg, p < 0,001) quando comparados com pacientes submetidos à terapia diurética padrão. Os níveis de creatinina pós-intervenção, no entanto, não diferiram entre os grupos (diferença média de -0,25 mg/dL CI 95% -0,56 a 0,06mg/dL p = 0,112). Não observamos evidências de redução de risco de mortalidade por todas as causas em pacientes submetidos à UF quando comparados àqueles tratados com terapia diurética padrão (RR combinado = 1,00 CI 95% 0,64 1,56, p = 0,993). Conclusão: Quando comparado à terapia diurética padrão, o uso de UF no tratamento de sobrecarga hídrica em ICAD resultou em uma redução significativa de peso em 48 horas. No entanto, não foi observada melhoria significativa na redução dos níveis de creatinina ou na taxa de ...

ABSTRACT

OBJECTIVES: To contrast the static balance in patients presenting diabetes mellitus type 2 (DM2) with and without polyneuropathy (DPN); and to correlate the rates from the scale Diabetic Neuropathy Examination (DNE) with the mean ratio of the center of pressure (CoP). SUBJECTS AND METHODS: Twenty patients, aged between 40 and 54, presenting DM2 and classified, according to DNE scale, in groups with (n = 10) and without (n = 10) DPN, were compared. Static balance was evaluated by means of the CoP mean ratio on a Wii Balance Board® under the conditions of open and closed eyes. After normality verification (Shapiro-Wilk), balance between both groups was compared by means of the Student t test and Mann-Whitney U test, as applicable. DNE rating was correlated with the mean ratio of CoP in the group with DPN, considering a significance level p < 0.05. RESULTS: Significant differences (p = 0.049) were found under the condition of closed eyes, with greater CoP ratio in the group with DPN (0.548 cm vs. 0.442 cm). The group with DPN showed a tendency (p = 0.059) towards a greater CoP mean ratio under the open eyes condition (0.351 cm vs. 0.239 cm). There was a strong correlation (r = 0.751) between the DNE rating and the CoP mean ratio under the closed eyes condition (p = 0.012). CONCLUSIONS: Patients showing DPN demonstrated worse static balance than patients without DPN in the closed eyes condition. Furthermore, the higher the rating in DNE, the stronger the displacement of CoP, which may be associated with higher risk of falls.


OBJETIVOS: Comparar o equilíbrio estático em pacientes com diabetes melito tipo 2 (DM2) com ou sem polineuropatia diabética (PND) e correlacionar os escores da escala de Exame da Neuropatia Diabética (EDN) com a média da relação do centro de pressão (CoP). SUJEITOS E MÉTODOS: Vinte pacientes, com idades entre 40 e 54 anos, que apresentavam DM2 e classificados, de acordo com a escala EDN, em grupos com (n = 10) e sem (n = 10) PDN foram comparados. O equilíbrio estático foi avaliado segundo a média da relação do CoP em um Wii Balance Board® na condição com os olhos abertos e os olhos fechados. Depois da verificação da normalidade (Shapiro-Wilk), o equilíbrio entre os dois grupos foi comparado por meio dos testes t de Student e U de Mann-Whitney, como aplicável. O escore na EDN foi correlacionado com a média da relação do CoP no grupo com PND, considerando um nível de significância de p < 0,05. RESULTADOS: Diferenças significativas (p = 0,049) foram observadas nas condições de olhos fechados, com uma maior média da relação do CoP no grupo com PND (0,548 cm vs. 0,442 cm). O grupo com PND mostrou uma tendência (p = 0,059) para maior média da relação do CoP na condição com os olhos abertos (0,351 cm vs. 0,239 cm). Foi observada uma forte correlação (r = 0,751) entre o escore EDN e a média da relação do CoP na condição com os olhos fechados (p = 0,012). CONCLUSÕES: Os pacientes com PND demonstraram pior equilíbrio estático do que os pacientes sem PND na condição com os olhos fechados. Além disso, quanto maior o escore no EDN, mais forte o deslocamento do CoP, o que pode estar associado com maior risco de quedas.

ABSTRACT

Nowadays, Diabetic Neuropathy (DN) is considered the most common cause of peripheral neuropathy in clinical practice. It can affect sensitive, motor or autonomic nerve fibers, with symmetric, asymmetric, acute or chronic presentations. Due to this variability, with multiple physiopathologic mechanisms involved, a complex clinical classification has been used until recently. The aim of this review is to present a new classification of diabetic neuropathy, based on its physiopathology. It is divided in metabolic microvascular and hypoxic, autoimmune and inflammatory, compressive, secondary to complications ofdiabetes and related to treatment. It must be understood that DN is notjust a functional disease, but a complication of diabetes with molecular and pathological substrates caused by hyperglycemia. Therefore, normalization of blood glucose is a fundamental step towards the successful prevention and treatment of DN.

ABSTRACT

BACKGROUND: The progression of diabetes and the challenge of daily tasks may result in changes in biomechanical strategies. Descending stairs is a common task that patients have to deal with, however it still has not been properly studied in this population. OBJECTIVES: We describe and compare the net joint moments and kinematics of the lower limbs in diabetic individuals with and without peripheral neuropathy and healthy controls during stair descent. METHOD: Forty-two adults were assessed: control group (13), diabetic group (14), and neuropathic diabetic group (15). The flexor and extensor net moment peaks and joint angles of the hip, knee, and ankle were described and compared in terms of effect size and ANOVAs (p<0.05). RESULTS: Both diabetic groups presented greater dorsiflexion [large effect size] and a smaller hip extensor moment [large effect size] in the weight acceptance phase. In the propulsion phase, diabetics with and without neuropathy showed a greater hip flexor moment [large effect size] and smaller ankle extension [large effect size]. CONCLUSION: Diabetic patients, even without neuropathy, revealed poor eccentric control in the weight acceptance phase, and in the propulsion phase, they showed a different hip strategy, where they chose to take the leg off the ground using more flexion torque at the hip instead of using a proper ankle extension function.


CONTEXTUALIZAÇÃO: A progressão do Diabetes Mellito e as atividades desafiadoras do dia a dia podem resultar em mudanças da estratégia biomecânica adotada. Descer escadas é uma tarefa comum do dia a dia, vivenciada pelos pacientes, mas ainda não foi satisfatoriamente estudada nessa população. OBJECTIVOS: Descrever e comparar os momentos articulares e a cinemática de membros inferiores em indivíduos diabéticos com e sem a neuropatia periférica e controles saudáveis durante o descer escadas. MÉTODO: Quarenta e dois adultos foram avaliados: grupo controle (13), grupo diabético (15) e grupo de diabéticos neuropatas (14). Os picos flexores e extensores dos momentos articulares e os ângulos articulares de quadril, joelho e tornozelo foram comparados e descritos por análise do tamanho do efeito e ANOVAs (p<0,05). RESULTADOS: Na fase de aceitação do peso, ambos os grupos diabéticos apresentaram maior ângulo de dorsiflexão de tornozelo [tamanho de efeito grande] e menor momento extensor de quadril [tamanho de efeito grande]. Na fase de propulsão, diabéticos com e sem a neuropatia apresentaram maior momento flexor de quadril [tamanho de efeito grande] e menor ângulo de extensão de tornozelo [tamanho de efeito grande]. CONCLUSÃO: Pacientes diabéticos, mesmo antes da neuropatia instalada, revelaram um pobre controle excêntrico na fase de aceitação do peso e, na fase de propulsão, esses pacientes mostraram uma estratégia diferente ao levar o membro inferior à frente a partir de um maior torque flexor de quadril ao invés de usar uma função extensora apropriada de tornozelo.

ABSTRACT

O diabetes mellitus (DM) é uma das enfermidades crônicas mais diagnosticadas nos últimos anos. A neuropatia diabética periférica (NP) é a complicação mais prevalente dessa doença, atingindo até 80% dos diabéticos, podendo modificar o equilíbrio. Este estudo teve por objetivo comparar o equilíbrio estático de indivíduos diabéticos neuropatas, diabéticos não neuropatas e indivíduos sem DM e averiguar a influência da visão nessa situação. Foram avaliados 30 indivíduos, divididos em três grupos diferentes: GC, 10 não diabéticos (média de idade 55,5±9,72 anos); GD: 10 diabéticos sem NP (54,4±7,76 anos); e GNP, 10 diabéticos com NP (60,4±5,35 anos). Cada indivíduo foi filmado nos planos frontal e sagital, com e sem visão, avaliado quadro a quadro no software Free Video to JPG Converter®, para a seleção dos momentos de maiores oscilações. As imagens foram quantificadas através da Biofotogrametria Computadorizada, utilizando-se o software SAPO. Os dados foram tratados estatisticamente no software Graph Pad Prism (versão 5). Os resultados evidenciam que o grupo GNP apresentou diferenças estatisticamente significantes nas amplitudes de oscilações no plano frontal e sagital, nas condições com e sem visão, quando comparado com os outros grupos (p=0,0001). Mediante os resultados, concluiu-se que a NP influencia negativamente na manutenção do equilíbrio estático, principalmente sem visão.


Diabetes mellitus (DM) is one of most chronic diseases diagnosed in recent years. Peripheral diabetic neuropathy (PN) is the most prevalent complication of the disease, reaching 80% of diabetics and it may modify the balance. This study intended to compare the static equilibrium of neuropathic diabetics, diabetic non-neuropathic and subjects without DM and investigate the influence of vision in this situation. Thirty subjects were evaluated, divided into three different groups: GC, 10 non-diabetic (average age 55.5±9.72 years); GD, 10 diabetic without NP (54.4±7.76 years); and GNP, 10 diabetic with NP (60.4±5.35 years). All subjects were filmed in the frontal and sagittal planes, with and without vision, and their movements were evaluated frame by frame in the software Free Video to JPG Converter® to select the moments of greatest oscillation. The images were quantified through computerized biophotogrammetry using the software SAPO. Data were statistically analyzed in Graph Pad Prism Software (version 5). The results pointed that the GNP group showed statistically significant differences in the amplitudes of oscillations in the frontal and sagittal, both with and without vision, compared with other groups (p=0.0001). With the results it can be concluded that NP has a negative influence on the maintenance of static balance, particularly without vision.

ABSTRACT

Diabetic polyneuropathy can be confirmed by nerve conduction studies. The data can be analyzed in the form of a combined index instead of individual parameters. METHODS: The combined index included five parameters of nerve conduction studies commonly used for evaluation of polyneuropathies. We evaluated sensitivity in 100 diabetic patients with suspected polyneuropathy, and specificity in 200 non-diabetic patients with suspected lumbosacral radiculopathy. All results were expressed in number of standard deviations (SD). RESULTS: The sensitivity of the combined index was 81 or 74%, and specificity was 97 or 98%, using respectively -2.0 or -2.5 SD as cutoff. The range of sensitivity of the other parameters was 57-65% or 48-56%, and specificity range was 96-98% or 98-100%, using the same criteria. DISCUSSION: The combined index had higher sensitivity and equivalent specificity compared to isolated parameters.


A polineuropatia diabética pode ser confirmada por estudos de condução nervosa. Os dados podem ser analisados por um índice combinado ao invés de parâmetros isolados. MÉTODOS: O índice combinado incluiu cinco parâmetros usados rotineiramente na avaliação de polineuropatias. Avaliamos a sensibilidade em 100 pacientes diabéticos com suspeita de polineuropatia e a especificidade em 200 pacientes não diabéticos com suspeita de radiculopatia lombossacral. Todos os resultados foram expressos em número de desvios-padrão (DP). RESULTADOS: A sensibilidade do índice combinado foi 81 ou 74%, e a especificidade foi 97 ou 98%, usando respectivamente -2,0 ou -2,5 DP como ponto de corte. A sensibilidade dos parâmetros isolados oscilou entre 57-65% ou 48-56%, e a especificidade foi 96-98% ou 98-100%, usando os mesmos critérios. DISCUSSÃO: O índice combinado apresentou melhor sensibilidade e especificidade equivalente aos parâmetros isolados.

ABSTRACT

Background & objectives: Vibration perception threshold (VPT) is considered as a gold standard for diagnosis of diabetic peripheral neuropathy. However, the data are sparse comparing the VPT with commonly used bedside modalities. This study was carried out to evaluate the usefulness of simple bed side screening modalities for peripheral neuropathy in patients with diabetes mellitus. Methods: A total of 1044 patients with diabetes mellitus attending the Diabetes clinic from January 2007 to May 2008, were included in this study. All subjects had a detailed clinical assessment including Diabetic Neuropathy Symptom (DNS) score, Diabetic Neuropathy Examination (DNE) score, ankle reflex, vibration sensation with a 128 Hz tuning fork, 10g Semmes-Weinstein monofilament and vibration perception threshold (VPT). Results: The prevalence of peripheral neuropathy was 34.9 per cent with VPT. Foot care practices were followed by only 214 (20.5%) of the study population. When compared with VPT, ankle reflex was the most sensitive (90.7%) but least specific (37.3%). The tuning fork and monofilament tests respectively had lower sensitivity (62.5 and 62.8%) but better specificity (95.3 and 92.9%) and accuracy (78.9 and 77.9%). Significant correlations were observed between the VPT score and the DNE (r = 0.532, P<0.001) and DNS (r = 0.546, P<0.001) scores and absent tuning fork sensation (r= 0.590; P<0.001), monofilament sensation (r= 0.573; P<0.001) and ankle reflex (r = 0.377, P= 0.01). Interpretation & conclusions: The present findings show that simple bed side tests are useful for assessing peripheral diabetic neuropathy, even in those subjects in whom foot care practices are not followed.

ABSTRACT

Con el objetivo de evaluar la relación entre la neuropatía autonómica cardiovascular (NACV) y el intervalo QT corregido (QTc) con la morbimortalidad cardiovascular en pacientes con diabetes mellitus tipo 2, se realizó el seguimiento a 5 años de 67 pacientes que acudieron a consulta externa del Servicio de Endocrinología. Se presentaron eventos cardiovasculares en 16 pacientes; el 82 por ciento completó el seguimiento y se encontró que el intervalo QTc prolongado fue la única variable que se asoció de forma significativa a morbimortalidad cardiovascular en el análisis de regresión logística múltiple (RR: 13,56; IC 95 por ciento: 2,01-91,36) (p=0,0074).


In order to evaluate the relationship between cardiovascular autonomic neuropathy and corrected QT interval (QTc) with cardiovascular morbidity and mortality in patients with type 2 diabetes mellitus, we followed up for 5 years 67 patients attending the outpatient Endocrinology Service. 82 percent completed follow-up and cardiovascular events occurred in 16 patients. We found that long QTc interval was the only variable significantly associated with cardiovascular morbidity and mortality in the multiple logistic regression analysis (RR: 13.56, 95 percent CI: 2.01-91.36) (p = 0.0074).

ABSTRACT

A Federação Internacional de Diabetes (/DF) publicou novos dados indicando a enormidade da epidemia mundial da doença. Esses dados demonstram que o diabetes afeta atualmente 246 milhões de pessoas em todo o mundo, sendo que 46% destes com idades entre 40 e 59 anos. Dados atuais predizem que, se nada for feito, o número total de portadores de diabetes ultrapassará 380 milhões de pessoas em 20 anos. O estilo de vida moderno trouxe inúmeras mudanças de hábito e comportamento, como menor tempo dedicado à prática de atividades físicas regulares, um cotidiano mais estressante, além da maior oferta de alimentos industrializados, ricos em carboidratos simples e gorduras, pobres em fibras, minerais e vitaminas. Atualmente dedica-se mais tempo a atividades em frente às telas de computadores e a jogos de videogame e programas de televisão. Como consequência, tem-se observado maior incidência de doenças metabólicas, tais como obesidade, diabetes mellitus tipo 2 (DM 2), hipertensão arterial sistêmica (HAS), dislipidemia e, portanto, doenças cardiovasculares (DCVs), gerando a necessidade crescente de pesquisas em busca de novas opções terapêuticas para estas doenças. O presente trabalho visa fazer uma breve revisão sobre os avanços terapêuticos do diabetes mellitus tipo 2.


The International Diabetes Federation (/DF) has published new data indicating the enormity of the diabetes epidemic in the globe. That data show that the disease now affects a staggering 246 million people worldwide, with 46% of a11 those affected in the 40-59 age group. The new data predict that the total number of people living with diabetes will skyrocket to 380 million within twenty years if nothing is done. The modern life style has brought many changes such as more variety of food rich in sugar, fat and poor in fiber, vitamins and minerals, less time to practice a regular physical activity and a more stressful lifestyle. Nowadays, people spend more time in front of their computers, playing video games and watching programs of TV. As a consequence, many metabolic diseases have been increasing such as obesity, type I1 diabetes mellitus, high blood pressure, hyperlipidemia and cardiovascular diseases, leading the growing necessity of researches for new therapeutic options to these diseases. This article is a short review of type II diabetes mellitus's new treatment.

ABSTRACT

Background: Glycine inhibits the formation of advanced glycation end products that may cause central and peripheral neuronal damage, affecting also the auditory nerve. Aim: To evaluate the effect of glycine on auditory nerve conduction and hearing level among patients with type 2 diabetes mellitus and auditory neuropathy. Material and Methods: Twenty grams of oral glycine per day were administered during 6 months to 28 type 2 diabetic patients aged 58 ± 6 years, with auditory pathway neuropathy. Hearing tests and evoked otoacustic potentials were performed regularly. Fifteen diabetic patients aged 49 ± 8 years, without auditory nerve neuropathy did not receive glycine and were followed as a control group. Results: Among patients receiving glycine, a significant improvement in left ear audiometry at 125, 250 and 500 Hz and right ear audiometry at 500 Hz, was observed. Waves I, III and V (p= 0.02) of evoked otoacustic potentials improved significantly in the left ear and wave I in the right ear. Among controls, waves V and III of evoked otoacoustic potentials had a significant impairment in the left ear. Conclusions: There was an improvement in auditory evoked potentials in patients receiving glycine and an impairment in untreated control patients.

ABSTRACT

OBJETIVO: A neuropatia diabética leva à diminuição ou perda da sensibilidade protetora do pé, tornando o diabético mais vulnerável ao trauma mecânico, consequentemente, levando-o à formação de feridas e eventualmente, perda segmentar nos membros inferiores. A profilaxia das complicações neuropáticas deve ser iniciada pela identificação do grau de neuropatia e, portanto, do comprometimento neurológico. O Pressure Specified Sensory DeviceTM foi desenvolvido para quantificar o limiar de pressão aplicada sobre a pele, necessário para que o paciente sinta o estímulo de um ponto estático, um ponto em movimento, dois pontos estáticos e dois pontos em movimento. É um meio direto para se avaliar os sistemas de fibras de adaptação lenta e rápida e seus respectivos receptores periféricos. MÉTODOS: Trinta e três pacientes diabéticos do tipo II, sem história prévia de feridas e/ou amputações nos pés foram avaliados neste estudo de corte transversal. A sensibilidade nos territórios cutâneos dos nervos plantar medial, calcâneo e o ramo profundo do nervo fibular foi avaliada usando os testes de um ponto estático (1PE), um ponto dinâmico (1PD), dois pontos estáticos (2PE) e dois dinâmicos (2PD). RESULTADOS: Nos três territórios nervosos examinados encontramos valores alterados para as modalidades estática e dinâmica em relação ao padrão de normalidade. As diferenças foram estatisticamente significantes com p < 0,05. CONCLUSÃO: A quantificação numérica do limiar de pressão cutânea nos permite tanto a avaliação do conjunto fibra/receptor, quanto à determinação do déficit funcional da fibra nervosa imposto pela neuropatia diabética.


OBJECTIVES: Neuropathy is a severe progressive loss of protective sensation in the feet, increasing patient vulnerability to mechanical trauma and consequently more prone to development of chronic wounds, major distortion of the foot bone architecture and to eventual limb amputation. Prophylaxis should be enforced to avoid foot ulceration and for this purpose, evaluation of the degree of loss of sensation on the skin is essential. The PSSD (Pressure Specified Sensory DeviceTM) was developed to quantify the threshold of pressure applied to the skin that the patient might recognize as positive. Pressure of one or two points is tested both statically and with movement, thus assessing the function of fast and slow response nerve fibers. METHODS: 33 diabetic patients, type II, with no previous history of wounds on the lower extremity were studied. The tests used were, one point static, one point moving and two points, static and moving on the cutaneous territory of the fibular nerve and posterior tibial nerve (two territories - medial plantar and calcaneous nerves). RESULTS: Altered values were observed for the static and dynamic tests over the three nerve territories studied. Differences were statically significant (p < 0.05). This numeric quantification of the threshold of pressure supports the evaluation of the status of the fiber/receptor structures as well as the functional deficit subsequent to diabetic neuropathy.

ABSTRACT

OBJECTIVE: To investigate and compare the influence of a previous history of foot ulcers on plantar pressure variables during gait of patients with diabetic neuropathy. INTRODUCTION: Foot ulcers may be an indicator of worsening diabetic neuropathy. However, the behavior of plantar pressure patterns over time and during the progression of neuropathy, especially in patients who have a clinical history of foot ulcers, is still unclear. METHODS: Subjects were divided into the following groups: control group, 20 subjects; diabetic neuropathy patients without foot ulcers, 17 subjects; and diabetic neuropathy patients with at least one healed foot ulcer within the last year, 10 subjects. Plantar pressure distribution was recorded during barefoot gait using the Pedar-X system. RESULTS: Neuropathic subjects from both the diabetic neuropathy and DNU groups showed higher plantar pressure than control subjects. At midfoot, the peak pressure was significantly different among all groups: control group (139.4±76.4 kPa), diabetic neuropathy (205.3±118.6 kPa) and DNU (290.7±151.5 kPa) (p=0.008). The pressure-time integral was significantly higher in the ulcerated neuropathic groups at midfoot (CG: 37.3±11.4 kPa.s; DN: 43.3±9.1 kPa.s; DNU: 68.7±36.5 kPa.s; p=0.002) and rearfoot (CG: 83.3±21.2 kPa.s; DN: 94.9±29.4 kPa.s; DNU: 102.5±37.9 kPa.s; p=0.048). CONCLUSION: A history of foot ulcers in the clinical history of diabetic neuropathy subjects influenced plantar pressure distribution, resulting in an increased load under the midfoot and rearfoot and an increase in the variability of plantar pressure during barefoot gait. The progression of diabetic neuropathy was not found to influence plantar pressure distribution.

ABSTRACT

OBJECTIVE: Diabetes mellitus is an established risk factor for cardiovascular events. Aims of the study were to assess left ventricular systolic and diastolic function in asymptomatic patients with type 2 diabetes and evaluate the relations among left ventricular function and specific diabetic complications. METHODS: Seventy-three normotensive patients with type 2 diabetes and no clinical evidence of cardiac disease were studied. Thirty-four healthy subjects served as control group. Echocardiographic studies were performed to assess left ventricular systolic and diastolic function. Microangiopathy was assessed by fundoscopy. Autonomic function was evaluated by standing blood pressure and heart rate response to Valsalva maneuver. RESULTS: Patients with type 2 diabetes had a lower ejection fraction (54 +/- 10.8 vs. 67 +/- 6.1%, p < or = 0.001), E-velocity (50.1 +/- 10.6 vs. 58.4 +/- 6.3 cm/s, p < or = 0.001), and E/A ratio of <1 (54.8 vs. 5.8%, p < or = 0.01) of the mitral diastolic flow compared with the control subjects, respectively. Patients with ejection fraction <50% had higher prevalence of retinopathy (52.9 vs. 26.7%, p < or = 0.05), abnormal blood pressure response to standing (52.9 vs. 7.1%, p < or = 0.001), and proteinuria (70.5 vs. 14.2%, p < or = 0.05). An inverse correlation was found between duration of diabetes and both ejection fraction (r = -0.53, p = 0.05) and E/A ratio (r = 0.36, p = 0.003). E/A ratio of <1 was associated with higher prevalence of retinopathy (45 vs. 18.1%, p < or = 0.05) and abnormal blood pressure response to standing (25 vs. 9%, p < or = 0.05). Multiple logistic regression model showed that diabetes was the strongest independent correlate of diastolic dysfunction (odds ratio 8.91, 95% CI: 4.18-18.52, p < or = 0.001). CONCLUSION: Asymptomatic diabetic patients have reduced left ventricular systolic and diastolic function as compared with healthy subjects. Left ventricular systolic and diastolic abnormalities are correlated with the duration of diabetes and with diabetic microangiopathies, like retinopathy and neuropathy. Diabetes mellitus is the strongest independent correlate of left ventricular diastolic dysfunction.
