Prevalence of electrocardiographic alterations in athletes associated with cardiovascular risk parameters / Prevalencia de alteraciones electrocardiográficas en deportistas asociadas a parametros de riesgo cardiovascular

Sport induces cardiac adaptations that are manifested with specific electrocardiographic alterations. This study was carried out in view of the need to identify the relationship between these electrocardiographic alterations with cardiovascular and demographic variables and physical exercise performed. Methodology: a descriptive cross-sectional study in 370 individuals, 211 men and 159 women (36 ± 13 years) that were distributed in three groups: male athletes, female athletes, and non-athlete men and women. Results: 51.08% of the studied subjects presented electrographic alterations, more frequent in athletes. Demographic and cardiovascular variables and the time of physical exercise performed were significantly associated with certain electrocardiographic alterations; the risk of presenting any of the alterations in athletes could be estimated based on the variables set out. Conclusion: There are associations between specific electrocardiographic alterations and cardiovascular, demographic and type of exercise variables that could classify athletes according to cardiovascular risk profiles (AU)

Predictors of Diabetic Foot Reulceration beneath the Hallux.

AIMS: To evaluate the factors that predict reulceration beneath the hallux in people with a history of diabetic foot ulceration. METHODS: A prospective study conducted between January 2012 and December 2014 was performed in a diabetic foot unit to assess the risk factors associated with hallux reulceration. Sixty patients with diabetic neuropathy and a history of previous ulcer were consecutively included. Sociodemographic factors and comorbidities plus the biomechanical and radiographic factors were obtained. Follow-up on participants was conducted every month, and they wore offloading therapeutic footwear and custom-made insoles. Hallux reulceration during the follow-up period was assessed as the main outcome measure in the study. RESULTS: Patients were followed up during 29 (14.2-64.4) months. Twenty-nine patients (52%) developed a new ulceration: 9 patients (31%) in the hallux and 20 (69%) in other locations. Functional hallux limitus (p = 0.005, 95% CI (2.097-73.128), HR 12.384) and increased body mass index (p = 0.044, 95% CI (1.003-1.272), HR 1.129) were associated with the hallux ulceration-free survival time in the multivariate Cox model. CONCLUSIONS: Obesity and the presence of functional hallux limitus increase the probability of developing hallux reulceration in patients with diabetic neuropathy and a history of ulcers.

Forefoot ulcer risk is associated with foot type in patients with diabetes and neuropathy.

AIMS: To stratify the ulceration risk according to the foot morphology in people with diabetes and a history of forefoot neuropathic ulceration. METHODS: A cross-sectional study was performed on 139 neuropathic individuals with diabetes and previous forefoot ulcers between January 2012 and February 2014. Foot position of the participants was evaluated by using the foot-posture index. A multivariate analysis adjusted for confounding variables was performed with the ulceration risk factors that were found in the univariate analysis. RESULTS: Two hundred and fifty-eight feet were analysed, 104 (40.3%) feet had a history of ulceration on the forefoot and 154 (59.7%) feet had no previous ulceration. Two positive tests of neuropathy (p<0.001; CI[1.961-6.249] OR 3.500), presence of deformities (p=0.043; CI[1.020-3.599] OR 1.916) and foot type (p=0.039) showed an association with ulceration risk in multivariate analyses. Pronated feet showed a higher risk of ulceration than supinated feet (p=0.011; CI[1.253-5.708] OR 2.675), while significant differences between neutral and supinated feet were not found (p=0.221; CI[0.719-2.753] OR 1.476). CONCLUSIONS: A pronated foot has a higher risk of ulceration on the forefoot in neuropathic people with deformities and diabetes mellitus. Foot type should be evaluated in people at risk of ulceration.

Introducción. Niveles altos de carga bacteriana han demostrado una influencia negativa en la cicatrización de las úlceras. El uso de apósitos antimicrobianos con plata puede controlar el nivel de carga bacteriana de las heridas. El objetivo de este estudio fue evaluar la respuesta terapéutica de un apósito de fibra de alginato e hidrocoloide, con plata, en úlceras infectadas de pie diabético. Material y métodos. Se analizó una serie de casos de 6 pacientes con úlceras de pie diabético, sin enfermedad vascular periférica y diagnosticadas de colonización crítica y/o infección local mediante la recogida de signos clínicos inflamatorios. Los pacientes fueron tratados durante un período mínimo de 2 semanas. Se analizó el porcentaje de reducción del área de la úlcera desde el día de la inclusión hasta la retirada del apósito antimicrobiano. Resultados. El tratamiento tuvo una mediana de 5 semanas con una duración mínima de 2 y máxima de 6. La mediana del porcentaje de reducción de la superficie de las heridas fue de 47,7% (rango: 0,5%-90%). La media del porcentaje de reducción de la lesión a las 2 semanas fue del 58% y a la tercera semana del 67,14%. Todos los pacientes habían disminuido sus dimensiones a las 3 semanas de tratamiento de forma significativa (p<0,05). Conclusión. El uso de un apósito de fibra de alginato e hidrocoloide, con plata, favorece la cicatrización de las úlceras de pie diabético con infección local, reduciendo los signos clínicos inflamatorios de forma significativa en un período de 3 semanas (AU)

Introduction: High levels of bacterial load have shown a deleterious influence on wound healing. Using antimicrobial dressings can control ulcers’ bioburden. The aim of our study was to evaluate the improving of infected diabetic foot ulcers due an alginate’s fiber and hydrocolloid silver dressing. Material and Methods: We analysed a case series of 6 patients with diabetic foot ulcers without peripheral vascular disease and diagnosed from critical colonization and / or local infection according the presence of inflammation clinical signs. Patients were treated for a minimum period of two weeks. We analysed the percentage reduction in ulcer area from the day of enrolment to antimicrobial dressing removal. Results: The duration of treatment had a median of 5 weeks with a minimum of 2 weeks and up to 6. The median percentage of area reduction of the wounds was 47.7% (range: 0.5%-90%). The mean percentage reduction on the lesion was 58% from 2 weeks and 67.14% at 3 weeks. All patients had reduced significantly their size at 3 weeks from beginning of treatment (p<0.05). Conclusion: The use of an alginate’s fiber and hydrocolloid silver dressing promotes healing on diabetic foot ulcers with local infection, reducing the inflammatory clinical signs significantly over a period of three weeks (AU)

Relationship of limited joint mobility and foot deformities with neurological examination in patients with diabetes.

AIMS: The aim is to define the association of forefoot deformity and limited joint mobility in the ankle and hallux joints in patients with diabetes mellitus subject to different diagnostic tests for diabetic neuropathy. Prospective study with 118 type 2 diabetic patients (68 men, mean age of 65.6±9.9 years) enrolled consecutively from the Diabetic Foot Unit of the Complutense University of Madrid subject to evaluation of plantar surface sensitivity by 10-g Semmes-Weinstein Monofilament, vibratory threshold by biothesiometer, and sudomotor dysfunction by Neuropad®. The patients presented with limited joint mobility of the ankle and the first metatarsophalangeal joints, and forefoot deformities were registered. Statistical analysis was done through a univariate model to test the association between neurological and biomechanical alteration. There was an association of abnormal Monofilament (p=0.01; OR=3.9) and biothesiometer tests (p=0.01; OR=2.6) with the presence of forefoot deformity. Furthermore, a relation was found between abnormal Monofilament (p=0.02; OR=4.8) and biothesiometer (p<0.00; OR=12.8) tests with limited mobility of the first metatarsophalangeal joint both in loading and off-loading. Abnormal sudomotor function test was related with limited joint mobility of the ankle joint with the knee flexed (p=0.04; OR=2.8). CONCLUSIONS: The results of this study show discordance between biomechanical abnormalities and neuropathy depending on the diagnostic test used. Tests that assess large myelinated nerve fibers are associated with the presence of deformities. Abnormal sudomotor function test is associated with limited joint mobility and this test has a greater capacity for selecting patients at risk.
