Effects of Monochromatic Infrared Light on Painful Diabetic Polyneuropathy: Randomized Controlled Trial.

PURPOSE: To evaluate the effect of 890 nm Monochromatic Infrared Light (MIR) associated with a physical therapy protocol on pain in individuals with diabetic Distal Symmetric Polyneuropathy. METHODS: Randomized, parallel, double-blind controlled trial conducted with individuals randomly allocated into two groups: an experimental group (EG) with the application of 890 nm MIR associated with physical therapy and a control group that received the same treatment protocol without MIR application. Both groups underwent 18 treatment sessions and were followed up for 10 weeks. Pain assessment took place at four times using the instruments: Leeds Assessment of Neuropathic Symptoms and Signs, Douleur Neuropathique 4, and Brief Pain Inventory. Descriptive, inferential statistics and probabilistic estimates of the magnitude of the intervention's effect on neuropathic pain were used in data analysis (5% significance level). RESULTS: A total of 144 patients were allocated to groups. Lower levels of pain were observed for the EG after 6 weeks of intervention (p < .001) and 30 days after the intervention ended (p < .001). Pain intensity was lower and sleep quality improved (p < .001) for the experiment group, especially in people with severe pain. CONCLUSIONS: 890 nm MIR associated with a physical therapy protocol alleviated pain in people with Diabetic Painful Polyneuropathy after 6 weeks of follow-up, showing to be a promising alternative for the control of neuropathic pain due to diabetes mellitus. CLINICAL IMPLICATIONS: 890 nm MIR improves Painful Diabetic Polyneuropathy patient care due to relief of neuropathic pain.

The association of diabetic peripheral neuropathy with cardiac autonomic neuropathy in individuals with diabetes mellitus: A systematic review.

This systematic review aimed to explore the relationship between diabetic peripheral neuropathy (DPN) and cardiac autonomic neuropathy (CAN) in individuals with type 1 and 2 diabetes mellitus (DM). METHODS: The systematic review follow the protocol registered in Prospero (CRD42020182899). Two authors independently searched the PubMed, Scopus, Embase, Cochrane, and Web of Science databases. Discrepancies were resolved by a third author. The review included observational studies investigating the relationship between CAN and DPN in individuals with DM. RESULTS: Initially, out of 1165 studies, only 16 were selected, with 42.8 % involving volunteers with one type of diabetes, 14.3 % with both types of diabetes and 14.3 % not specify the type. The total number of volunteers was 2582, mostly with type 2 DM. It was analyzed that there is a relationship between CAN and DPN. It was observed that more severe levels of DPN are associated with worse outcomes in autonomic tests. Some studies suggested that the techniques for evaluating DPN might serve as risk factors for CAN. CONCLUSION: The review presents a possible relationship between DPN and CAN, such as in their severity.

Affordable web-based foot-ankle exercise program proves effective for diabetic foot care in a randomized controlled trial with economic evaluation.

The aim of this study was to shed light on a crucial issue through a comprehensive evaluation of the cost-effectiveness and cost-utility of a cutting-edge web-based foot-ankle therapeutic exercise program (SOPeD) designed for treating modifiable risk factors for ulcer prevention in individuals with diabetes-related peripheral neuropathy (DPN). In this randomized controlled trial, 62 participants diagnosed with DPN were assigned to the SOPeD software or received usual care for diabetic foot. Primary outcomes were DPN symptoms and severity, foot pain and function, and quality-adjusted life years (QALYs). Between-group comparisons provided 95% confidence intervals. The study also calculated incremental cost-effectiveness and cost-utility ratios (ICERs), analyzed direct costs from a healthcare perspective, and performed a sensitivity analysis to assess uncertainty. The web-based intervention effectively reduced foot pain, improved foot function and showed favorable cost-effectiveness, with ICERs ranging from (USD) $5.37-$148.71 per improvement in different outcomes. There is a high likelihood of cost-effectiveness for improving DPN symptoms and severity, foot pain, and function, even when the minimum willingness-to-pay threshold was set at $1000.00 USD. However, the intervention did not prove to be cost-effective in terms of QALYs. This study reveals SOPeD's effectiveness in reducing foot pain, improving foot function, and demonstrating cost-effectiveness in enhancing functional and clinical outcomes. SOPeD stands as a potential game-changer for modifiable risk factors for ulcers, with our findings indicating a feasible and balanced integration into public health systems. Further studies and considerations are vital for informed decisions to stakeholders and the successful implementation of this preventive program on a larger scale.Trial Registration: ClinicalTrials.gov, NCT04011267.

Therapeutic Interventions to Improve Static Balance in Type 2 DiabetesMellitus: A Systematic Review and Meta-Analysis.

INTRODUCTION: Diabetes mellitus (DM) is a metabolic disorder characterized by an abnormal increase in blood glucose levels resulting from insulin secretion and/or dysfunctional activity that can lead to several serious complications in addition to decreased postural balance. OBJECTIVE: This study aimed to identify and analyze the main interventions used to improve static balance in patients with DM. METHODS: For the selection of articles, a bibliographic search was performed using PubMed, Scopus, Web of Science, Embase, and Cochrane databases. Only clinical trials that investigated the effect of training on static balance in adults with type 2 DM were selected, and 34 studies were included. RESULTS: The search resulted in the identification of 2681 articles, and of these, 31 were eligible for the study. The identified interventions were proprioceptive, aerobic, resistance training on platforms, in virtual reality, and Tai Chi. The main results obtained were an increase in time in the one-leg stance, Romberg test, and tandem position, a significant increase in the Berg Balance Scale score and balance index, and a reduction in the variables of postural sway. CONCLUSION: There are a variety of effective training methods for improving static balance, and the choice of intervention to be applied goes beyond proven effectiveness, depending on reproducibility and/or financial cost.

The effects of the use of customized silicone digital orthoses on pre-ulcerative lesions and plantar pressure during walking in people with diabetic neuropathy: A study protocol for a randomized controlled trial.

Background: People with diabetes and diabetic peripheral neuropathy (DPN) often develop calluses due to toe misalignment and increased plantar pressure. Untreated, these issues can progress into ulcers, making early intervention crucial. This trial protocol aims to evaluate the efficacy and safety of customized silicone digital orthoses in preventing ulcers, pre-ulcerative lesions, and peak pressure during gait in people with DPN. Methods: In this superiority randomized controlled parallel trial with single-blind assessment, 60 participants will be allocated to the control group (CG) or the intervention group (IG). The CG will receive specialized nurse-administered foot care, including callus removal, nail care guidance, and self-care education. The IG will receive the same care plus a customized silicone orthosis for toe realignment for 6 months. Assessments will occur at baseline and 3 and 6 months for the primary outcomes (pre-ulcerative lesions and ulcer incidence) and secondary outcomes (pressure distribution, foot function and health, quality of life, safety, and comfort). Two-way ANOVAs (p < .05) will assess group, time, and group by time effects following an intention-to-treat approach. Conclusion: Although recommended for foot ulcer prevention, custom silicone orthosis adoption remains limited due to the low certainty of evidence. This trial seeks to provide more consistent evidence for the use of toe orthoses in preventing callus and ulcer formation for individuals with DPN.

Do you mind the role of spinal sensory block duration in a crucial endocrine disorder of diabetes mellitus? A prospective observational study

SUMMARY OBJECTIVE: Diabetes mellitus, per se, is a global health concern, which is often accompanied by complications such as diabetic neuropathy. This prospective observational study purposed to assess the durations of spinal sensory block and motor blocks in individuals with and without diabetes mellitus who had undergone spinal anesthesia. METHODS: This study incorporated 80 cases, which were evenly divided into spinal sensory block without diabetes mellitus and spinal sensory block with diabetes mellitus. Various parameters were recorded at different time points, including heart rate, mean arterial blood pressure, SpO2, and spinal block characteristics. Notable measures included maximum spinal sensory block onset time, time to reach the 10th thoracic vertebra (T10), maximal spinal sensory block, time for Bromage scores, and block regression while controlling for age-related variations. RESULTS: Patients in the diabetic group exhibited extended block durations, with significant differences in heart rate noted at specific time points. Regarding the spinal block characteristics, the "maximum onset of SSB" and the "time to reach the T10" were more prolonged in the SSBwDM without significance. Maximum sensory spinal sensory block did not differ. However, some cases in the SSBwDM displayed blocks extending up to the T6. The times to achieve Bromage motor block scores 1-3 were shorter in SSBwDM and lost significance regarding age. Notably, the regression time was longer in SSBwDM, which held significance for both parameters. CONCLUSION: Diabetic cases commonly encounter prolonged block durations post-subarachnoid intervention, potentially linked to nerve sensitivity, age-related changes, and glycemic control. As such, attenuated local doses for diabetic neuropathic cases may enhance early mobilization, attenuate thromboembolic events, and expedite gastrointestinal recovery.

Impact of streptozotocin-induced diabetes on experimental masseter pain in rats

Abstract This study aimed to assess the influence of streptozotocin (STZ)-induced diabetes on the nociceptive behavior evoked by the injection of hypertonic saline (HS) into the masseter muscle of rats. Forty male rats were equally divided into four groups: a) isotonic saline control, which received 0.9% isotonic saline (IS), (Ctrl-IS); b) hypertonic saline control, which received 5% HS (Ctrl-HS); c) STZ-induced diabetic, which received IS, (STZ-IS); d) STZ-induced diabetic, which received HS (STZ-HS). Experimental diabetes was induced by a single intraperitoneal injection of STZ at dose of 60 mg/kg dissolved in 0.1 M citrate buffer, and 100 μL of HS or IS were injected into the left masseter to measure the nociceptive behavior. Later on, muscle RNA was extracted to measure the relative expression of the following cytokines: cyclooxygenase-2 (COX-2), tumor necrosis factor (TNF-α), and interleukins (IL)-1β, -2, -6, and -10. One-way analysis of variance (ANOVA) was applied to the data (p < 0.050). We observed a main effect of group on the nociceptive response (ANOVA: F = 11.60, p < 0.001), where the Ctrl-HS group presented the highest response (p < 0.001). However, nociceptive response was similar among the Ctrl-IS, STZ-IS, and STZ-HS group (p > 0.050). In addition, the highest relative gene expression of TNF-α and IL-6 was found in the masseter of control rats following experimental muscle pain (p < 0.050). In conclusion, the loss of somatosensory function can be observed in deep orofacial tissues of STZ-induced diabetic rats.

Vitaminas B neurotrópicas y neuropatía periférica: estado del arte y acuerdo de expertos / Neurotropic B vitamins and peripheral neuropathy: State of the art and agreement of experts

Propósito: La neuropatía periférica tiene un espectro clínico inespecífico y multifactorial, con frecuente subdiagnóstico y terapéutica de eficacia variable. Existe una heterogénea prescripción de vitaminas B, las cuales pueden desempeñar un rol importante en el manejo de diferentes neuropatías; sin embargo, en Colombia no existen guías clínicas al respecto. El propósito de este trabajo es orientar en el reconocimiento temprano de las neuropatías periféricas y generar recomendaciones sobre el uso adecuado de vitaminas B neurotrópicas. Descripción de la metodología: Acuerdo de expertos sobre la neuropatía periférica y el rol terapéutico de las vitaminas B con énfasis en la epidemiología en Colombia, diagnóstico y tratamiento. Contenidos: En Colombia, la prevalencia de neuropatía periférica se estima cercana al 10 %, sin embargo, no hay datos recientes. Dentro de las etiologías más frecuentes se encuentran la neuropatía diabética, infecciosa, inflamatoria, carenciales, toxica y farmacológica. Se recomiendan las siguientes herramientas de tamizaje en población de riesgo: DN4, MNSI, test de monofilamento, test de vibración y valoración de reflejos. Las vitaminas B1, B6 y B12 son seguras, accesibles y pueden ser eficaces en neuropatía periférica, incluso cuando el déficit no ha sido demostrado, pero con requerimientos particulares en su administración conjunta. Conclusiones: Las neuropatías periféricas son un reto diagnóstico y terapéutico que requiere la identificación oportuna para el tratamiento de la etiología subyacente y el control de síntomas. El uso de vitaminas B neurotrópicas es efectivo y seguro en neuropatía periférica carencial, y también parece ser eficaz en el manejo de neuropatías periféricas de diferentes etiologías.

Purpose: Peripheral neuropathy has a nonspecific and multifactorial clinical spectrum, with frequent underdiagnosis and therapeutics of variable efficacy. There is a high but heterogeneous prescription of B vitamins, which can play an important role in the management of different neuropathies; however, in Colombia there are no clinical guidelines in this regard. The purpose of this article is to guide the early recognition of peripheral neuropathy and generate recommendations on the proper use of neurotropic B vitamins. Description of the methodology: Expert agreement on peripheral neuropathy and the therapeutic role of B vitamins with emphasis on epidemiology in Colombia, diagnosis and treatment. Contents: In Colombia, there are no recent data to estimate the prevalence of peripheral neuropathy; the main etiologies are: diabetes mellitus, nutritional deficiencies, herpes zoster and neuropathies due to chemotherapy. Given risk factors in the anamnesis, the use of DN4, MNSI, monofilament test, vibration test and assessment of reflexes is recommended. Vitamins B1, B6, and B12 are safe and can be effective in peripheral neuropathy, even when the deficit has not been demonstrated, but with special requirements in their joint administration. Conclusions: peripheral neuropathies are a diagnostic and therapeutic challenge, and require timely identification, for the treatment of the underlying etiology and symptom control. The use of neurotropic B vitamins is effective and safe in deficient peripheral neuropathy, and also appears to be effective in the management of peripheral neuropathies of different etiologies.

Potential predictive effect of mechanical properties of the plantar skin and superficial soft tissue, and vibration perception on plantar loading during gait in individuals with diabetes.

BACKGROUND: This exploratory study aimed to investigate the extent to which mechanical properties of the plantar skin and superficial soft tissue (hardness, stiffness, and thickness) and vibration perception thresholds (VPTs) predict plantar pressure loading during gait in people with diabetes compared to healthy controls. METHODS: Mechanical properties, VPTs, and plantar loadings during gait at the heel and first metatarsal head (MTH) of 20 subjects with diabetes, 13 with DPN, and 33 healthy controls were acquired. Multiple regression analyses were used to predict plantar pressure peaks and pressure-time integrals at both locations based on the mechanical properties of the skin and superficial soft tissues and VPTs. RESULTS: In the diabetes group at the MTH, skin hardness associated with 30-Hz (R2 = 0.343) and 200-Hz (R2 = 0.314) VPTs predicted peak pressure at the forefoot. In the controls at the heel, peak pressure was predicted by the skin thickness, hardness, and stiffness associated with 30-Hz (R2 = 0.269, 0.268, and 0.267, respectively) and 200-Hz (R2 = 0.214, 0.247, and 0.265, respectively) VPTs. CONCLUSION: The forefoot loading of people with diabetes can be predicted by the hardness of the skin when combined with loss of vibration perception at low (30-Hz) and high (200-Hz) frequencies. Further data from larger sample sizes are needed to confirm the current findings.

Neuropatía Diabética: Una revisión narrativa de fisiopatología, diagnóstico y tratamiento

La neuropatía diabética se presenta hasta en el 60 % de los pacientes diabéticos. La neuropatía diabética periférica es la causa más común de neuropatía en el mundo. La fisiopatología de la neuropatía diabética involucra daño periférico nervioso por acumulación de productos tóxicos derivados de la hiperglicemia. El sistema nervioso central se ve posteriormente involucrado a través de sensibilización, disminución de la función del sistema inhibitorio y aumento en la excitabilidad del sistema de facilitación. La clínica más común se manifiesta de manera simétrica afectando fibras sensitivas pequeñas y grandes, aunque se han encontrado formas atípicas de presentación. Las pruebas diagnósticas confirmatorias se reservan para la duda diagnóstica, casos de síntomas atípicos o investigación. El consenso en cuanto a tratamiento es el uso de gabapentinoides, antidepresivos tricíclicos e inhibidores de recaptura de serotonina y noradrenalina. Estas tres familias se consideran como primera línea de tratamiento.

Diabetic neuropathy occurs in up to 60% of diabetic patients. Diabetic peripheral neuropathy is the most common cause of neuropathy in the world. The pathophysiology of diabetic neuropathy involves peripheral nerve damage due to the accumulation of toxic products derived from hyperglycemia. The central nervous system is subsequently involved through sensitization, decreased function of the inhibitory system, and increased excitability of the facilitative system. The most common symptoms manifest symmetrically, affecting small and large sensory fibers, although atypical forms of presentation have been found. Confirmatory diagnostic tests are reserved for diagnostic doubt, atypical symptoms, or research. The consensus regarding treatment is the prescription of gabapentinoids, tricyclic antidepressants, and serotonin and norepinephrine reuptake inhibitors. These three families are considered the first line.

Introdução: o pé diabético é de origem neuropática e representa uma das complicações do diabetes mellitus, abrange várias condições patológicas, que incluem neuropatia, doença arterial periférica, neuroartropatia de Charcot, ulceração do pé e, em alguns casos, amputação. Objetivo: descrever o perfil clínico-metabólico de pacientes pé diabéticos frequentadores de uma Unidade Básica de Saúde (UBS). Material e Método: trata-se de um estudo descritivo exploratório com abordagem quantitativa. Foram avaliados 15 pacientes portadores de úlceras do pé diabético atendidos em uma Unidade Básica de Saúde de Altamira, estado do Pará, Brasil. Os dados foram submetidos à análise de acordo com os indicadores dos perfis investigados. Resultados: todos os pacientes possuem diabetes tipo II, baixos níveis de renda familiar e escolaridade. O Índice de Massa Corpórea (IMC) foi de 92%, circunferência abdominal 93%, proteína C reativa ultrassensível, interleucina-6 e hemoglobina glicada estavam superiores ao normal em mais da metade dos doentes, assim como a vitamina D estava deficiente em mais da metade dos pacientes. Conclusões: há barreiras ao manejo adequado dos portadores de pé diabético na atenção básica da cidade de Altamira que podem contribuir para o desenvolvimento de complicações macro e microvasculares. Recomendações técnicas direcionadas aos gestores locais contribuem para a atenção básica na região.

Introduction: the diabetic foot is of neuropathic origin and represents one of the complications of diabetes mellitus, encompasses several pathological conditions, including neuropathy, peripheral arterial disease, Charcot neuroarthropathy, foot ulceration, osteomyelitis and, in some cases, amputation. Objective: to describe the clinical-metabolic profile of diabetic foot patients attending a Basic Health Unit (BHU). Material and Method: this is a descriptive exploratory study with a quantitative approach. Fifteen patients with diabetic foot ulcers treated at the Basic Health Unit in Altamira, state of Pará, Brazil, were evaluated. The data were submitted to analysis according to the indicators of the investigated profiles. Results: all patients have Type 2 Diabetes, low level of family income and education. The Body Mass Index (BMI) was 92%, abdominal circumference (93%), Ultrasensitive C-Reactive Protein, Interleukin-6 and glycated hemoglobin were higher than normal in more than half of the patients, as well as vitamin D was deficient in more of half of the patients. Conclusions: there are barriers to the proper management of patients with diabetic foot in primary care in the city of Altamira that can contribute to the development of macro and microvascular complications. Technical recommendations directed at local managers contribute to primary care in the region.

Consensus-based recommendations on physical activity and exercise in patients with diabetes at risk of foot ulcerations: a Delphi study.

BACKGROUND: Patients with diabetes mellitus are exposed to important complications. Currently little evidence exist on the guidelines that these patients, at some risk of foot ulceration, should follow for physical exercise. OBJECTIVES: To reach a consensus among multidisciplinary and international experts on physical activity/exercise recommendations for patients with diabetes, according to foot ulcer risk. METHODS: Using a three-round Delphi method, a panel composed of 28 multidisciplinary experts in the management of diabetic foot assessed 109 recommendations on physical activity/exercise for patients with diabetes mellitus, according to their risk of foot ulcer. Consensus was assumed when 80% of responses matched the same category (agreement/disagreement). RESULTS: Twenty-nine experts participated in the first and second rounds of consultation, and twenty-eight did so in the third, reaching final agreement on 86 of the 109 recommendations considered (78.9%). The study, thus, generated a consensus set of recommendations concerning different aspects of diabetic footcare before, during, and after exercise (e.g. when to examine the foot, how to assess it, what type of sock and insole to use, what types of exercise to perform, and when it is advisable to return to activity after an ulceration). CONCLUSION: This Delphi study generated recommendations based on the consensus of international experts on physical activity and exercise by patient with diabetes at risk of ulceration. Recommendations considered the state of the foot and the patient's history and status before physical activity and included information on intensity, duration, frequency, and progressions of physical activity/exercise, and the use of custom-made plantar orthoses, shoe prescription, and the convenience of returning to physical activity after an ulceration.

Amazon Amandaba-Prevalence, Risk Factors and Self-Care Perception Associated with Diabetic Peripheral Neuropathy in Patients with Type 2 Diabetes: A Cross-Sectional Study.

BACKGROUND: Diabetic peripheral neuropathy (DPN) is one of the most common complications of type 2 diabetes mellitus. There is a gradual loss of protective sensation in the skin and the function of the foot joints, increasing the risk of injury as the disease progresses. The objective of this study was to verify whether socioeconomic factors, health risk factors, and self-care are associated with DPN. METHODS: Observational cross-sectional with 228 individuals of ≥30 years in Family Health Strategies in a city in the eastern Amazon, in northern Brazil, using questionnaires containing socioeconomic information, clinical and laboratory parameters, the Summary of Diabetes Self-Care Activities Questionnaire, and the Michigan Neuropathy Screening Instrument. RESULTS: The prevalence of DPN was 66.6%. The presence of neuropathy is associated with male gender, dyslipidemia, and increased microalbuminuria. Logistic regression analysis revealed male subjects' increased BMI and altered HDL levels were associated with DPN. CONCLUSIONS: In men with altered BMI, and dysregulation in biochemical parameters, neuropathy is more prevalent.

Seguindo o protocolo registrado no PROSPERO e descrito com base nas recomendações do PRISMA, foram selecionados estudos observacionais sem restrição a ano de publicação e idioma, envolvendo equilíbrio de DM em qualquer idade. RESULTADOS: Foram eleitos 20 artigos com indivíduos DM e NPD em um total de 1564 voluntários, demonstrando: DM causa mudança na velocidade e deslocamento do COP alterando o equilíbrio estático, a presença da NPD piora a estabilidade corporal devido as alterações sensitivo motoras. CONCLUSÃO: Indivíduos com DM e NPD demonstram alterações na estabilidade postural como velocidade e deslocamento do centro de pressão (COP) para as direções AP e ML, com ou sem informação visual e na presença da NPD.

INTRODUCTION: Type 2 diabetes mellitus (DM2) is a chronic systemic disease linked to changes in lifestyle, genetic and environmental factors, causing complications such as peripheral diabetic neuropathy (PDN). In addition, people with DM2 have a delay in nerve conduction in motor and sensory pathways, which can lead to changes in balance. OBJECTIVE: To describe static balance changes in patients with DM2. MATERIALS AND METHODS: The systematic review started in October 2021 with the last search occurring in March 2023, the articles were selected by two authors independently from the Pubmed, Scopus and Web of Science databases. Following the protocol registered in PROSPERO and described based on the PRISMA recommendations, observational studies were selected without restriction on year of publication and language, involving DM balance at any age. RESULTS: 20 articles were chosen with DM and NPD individuals in a total of 1564 volunteers, demonstrating that DM causes changes in the speed and displacement of the COP, altering the static balance and the presence of NPD worsens body stability due to sensory-motor changes. CONCLUSION: Individuals with DM and NPD demonstrate changes in postural stability such as velocity and displacement of the center of pressure (COP) for the AP and ML directions, with or without visual information and in the presence of DPN.

Objective: to describe the evolution of risk factors for the development of foot ulcers in patients with DM, in three subsequent exams over a period of 3 years, in a medical specialty center. Method: a descriptive, retrospective and longitudinal study, with 102 patients, between the years 2016 and 2019, who performed three sequential foot exams, based on the standard established by the international consensus of the diabetic foot, being use of footwear, collected from the Diabetic Foot System. Results: 86.27% of patients reported neuropathic symptoms, mainly burning, numbness and tingling. Most were hypertensive (74.71%) and elderly (67.65%), of these, 13.73% had previous infarction and 72.55% were female. From the first to the third examination, the "very low risk" increased 7.84% and the "low risk" 8.83%, while the "high risk" reduced 17.65%. Conclusion: the systematic clinical feet exam, associated with effective educational strategies, results in a more effective control of the risk of ulceration.

Autophagy and anti-inflammation ameliorate diabetic neuropathy with Rilmenidine

Purpose: To evaluate the neuroprotective effects of Rilmenidine on diabetic peripheral neuropathy (DPN) in a rat model of diabetes induced by streptozotocin (STZ). Methods: STZ (60 mg/kg) was administered to adult Sprague-Dawley rats to induce diabetes. On the 30th day after STZ administration, electromyography (EMG) and motor function tests confirmed the presence of DPN. Group 1: Control (n = 10), Group 2: DM + 0.1 mg/kg Rilmenidine (n = 10), and Group 3: DM + 0.2 mg/kg Rilmenidine (n = 10) were administered via oral lavage for four weeks. EMG, motor function test, biochemical analysis, and histological and immunohistochemical analysis of sciatic nerves were then performed. Results: The administration of Rilmenidine to diabetic rats substantially reduced sciatic nerve inflammation and fibrosis and prevented electrophysiological alterations. Immunohistochemistry of sciatic nerves from saline-treated rats revealed increased perineural thickness, HMGB-1, tumor necrosis factor-α, and a decrease in nerve growth factor (NGF), LC-3. In contrast, Rilmendine significantly inhibited inflammation markers and prevented the reduction in NGF expression. In addition, Rilmenidine significantly decreased malondialdehyde and increased diabetic rats' total antioxidative capacity. Conclusions: The findings of this study suggest that Rilmenidine may have therapeutic effects on DNP by modulating antioxidant and autophagic pathways.

Could an Internet-Based Foot-Ankle Therapeutic Exercise Program Modify Clinical Outcomes and Gait Biomechanics in People with Diabetic Neuropathy? A Clinical Proof-of-Concept Study.

Previous studies have shown the efficacy of foot-ankle exercises in people with diabetic peripheral neuropathy (DPN), but the quality of evidence is still low. This proof-of-concept study pursues preliminary evidence for potential clinical and gait biomechanical benefits from an internet-based foot-ankle therapeutic exercise program for people with DPN. We randomized 30 individuals with DPN (IWGDF risk category 1 or 2) into either the control group (CG) receiving the usual care or the intervention group (IG) receiving the usual care plus an internet-based foot-ankle exercise program, fully guided by the Sistema de Orientação ao Pé Diabético (SOPeD; translation: Diabetic Foot Guidance System) three times per week for 12 weeks. We assessed face-to-face clinical and biomechanical outcomes at baseline, 12 weeks, and 24 weeks (follow up). Participants had good adherence to the proposed intervention and it led to only mild adverse events. The IG showed improvements in the ankle and first metatarsophalangeal joint motion after 12 and 24 weeks, changed forefoot load absorption during foot rollover during gait after 24 weeks, reduced foot pain after 12 weeks, and improved foot function after 24 weeks. A 12-week internet-based foot-ankle exercise program using the SOPeD software (version 1.0) has the potential to reduce foot pain, improve foot function, and modify some important foot-ankle kinematic outcomes in people with DPN.

Detection of sudomotor alterations evaluated by Sudoscan in patients with recently diagnosed type 2 diabetes.

INTRODUCTION: Diabetic peripheral neuropathy (DPN) causes morbidity and affects the quality of life. Before diabetes diagnosis, neuropathic damage may be present. Sudoscan provides accurate measurement of the sudomotor function. This study aimed to assess the abnormalities detected by Sudoscan, offered estimates of DPN prevalence, and investigated the relationship between metabolic and clinical parameters. Additionally, we evaluated the diagnostic accuracy of the Sudoscan compared with monofilament and tuning fork tests for detecting DPN. RESEARCH DESIGN AND METHODS: Cross-sectional descriptive study including patients with type 2 diabetes for <5 years since diagnosis. We investigated the presence of DPN using a 128 Hz tuning fork test, the 10 g monofilament, and the sudomotor dysfunction in feet using Sudoscan. We compared patients with and without alterations in the Sudoscan. A logistic regression model analyzed variables independently associated with sudomotor dysfunction. RESULTS: From 2013 to 2020, 2243 patients were included, 55.1% women, age 51.8 years, and 17.1% with normal weight. Monofilament tests and/or tuning fork examination were abnormal in 29% (95% CI 0.23% to 0.27%) and 619 patients (27.6%, 0.25% to 0.29%) had sudomotor alterations. In logistic regression analysis, age (ß=1.01, 0.005-1.02), diastolic blood pressure (ß=0.98, 0.96-0.99), heart rate (ß=1.01, 1.00-1.02), glucose (ß=1.00, 1.00-1.03), albuminuria (ß=1.001, 1.000-1.001), beta-blockers=1.98, 1.21-3.24) and fibrate use=0.61, 0.43-0.87) were associated with sudomotor dysfunction. The AUC (area under the curve) for Sudoscan was 0.495 (0.469-0.522), with sensitivity and specificity of 24% and 71%, respectively. CONCLUSION: The Sudoscan identified an important proportion of patients with dysfunction, allowing prompt intervention to decrease the risk for complications. TRIAL REGISTRATION NUMBER: NCT02836808.
