Non-Targeted Metabolomic Analysis Reveals Serum Phospholipid Alterations in Patients with Early Stages of Diabetic Foot Ulcer.

Diabetic foot ulcer (DFU) is a common complication of type 2 diabetes mellitus (T2DM) characterized by ulcer formation, which can lead to the amputation of lower extremities. However, the metabolic alterations related to this complication are not completely elucidated. Therefore, we carried out a metabolomic analysis of serum samples obtained from T2DM adult patients diagnosed with diabetic foot ulcer in a cross-sectional, observational, and comparative study. Eighty-four volunteers were classified into the following groups: without T2DM (control group, n = 30) and with T2DM and different stages of diabetic foot ulcer according to Wagner-Meggitt classification system: DFU G0 (n = 11), DFU G1 (n = 14), DFU G2 (n = 16), and DFU G3 (n = 13). The non-target metabolomic profile followed by chemometric analysis revealed that lysophosphatidylethanolamine (16:1) could be proposed as key metabolite related to the onset of diabetic foot ulcer; however, this phospholipid was not affected by diabetic foot ulcer progression. Therefore, further studies are necessary to validate these phospholipids as biomarker candidates for the early diagnosis of diabetic foot ulcer in T2DM patients.

Costo-beneficio de la terapia en ambiente húmedo versus terapia tradicional: el caso de un paciente con úlcera en la extremidad inferior / Cost-effective therapy in wet environment versus traditional therapy: the case of a patient with lower limb ulcer

Actualmente, ha cobrado relevancia el uso de la terapia húmeda en la cura de las heridas crónicas; sin embargo, persiste el uso de la terapia tradicional como técnica para lograr la cicatrización de las mismas. El caso que presentamos tiene como propósito determinar el costobeneficio del empleo de apósitos de cura en ambiente húmedo versus cura tradicional en un paciente con úlcera en la extremidad inferior. Los resultados muestran que el coste es mayor con la terapia en ambiente húmedo; sin embargo, el periodo de cicatrización de la herida es menor en comparación con el tiempo de cicatrización que conlleva la cura tradicional; esto redunda en un beneficio para el paciente al alcanzar su recuperación en un menor tiempo. Estos hallazgos permiten proponer hipótesis para estudios posteriores bajo otro diseño metodológico, a fin de generar evidencia científica que coadyuve en la mejora de los procesos de atención en beneficio de la población con este tipo de padecimiento

Currently, it has become important to use the wet therapy in the treatment of chronic wounds, however, continue to use traditional therapy as a technique to achieve healing them. Hence, the present case report aims to determine the cost benefits of using dressings moist wound healing versus traditional cure in a patient with lower limb ulcer. Results show that the cost is higher therapy wet environment, however, the period of wound healing is lower compared to the healing time involved in traditional cure; this results in a benefit for the patient to achieve recovery in a shorter time. These findings lead us to propose hypotheses for further study under the other methodological design, in order to generate scientific evidence to assist with the improvement of care processes for the benefit of people with this type of condition
