RESUMEN

INTRODUCTION: Elevated plantar pressure (PP) constitutes a risk factor for developing foot ulcers. Once present, elevated PP increases morbidity and mortality in patients with diabetes. Given the high prevalence of overweight and obesity in the Mexican population, this study aimed to describe the magnitudes and the distribution of the PP observed in a sample of newly diagnosed patients with diabetes, adjusting for body mass index (BMI) groups (normal weight, overweight, grade I obesity, and grade II and III obesity). MATERIALS AND METHODS: A total of 250 volunteers attending a comprehensive care program for the management of type 2 diabetes received foot assessments that included vascular and neurological evaluation, the identification of musculoskeletal changes, and measurements of PP. RESULTS: Diabetic neuropathy and peripheral arterial disease were present in 21.6% and 11.2% of all participants. Musculoskeletal alterations were present in 70.8% of participants. A positive and significant correlation (p<0.001) was observed between BMI and the peak PP of all anatomical regions assessed. After adjusting for BMI, significant differences (p<0.001) were seen between groups. The metatarsal region, particularly under the third metatarsal head, denoted the highest magnitudes across all BMI. CONCLUSIONS: Periodic PP assessment is recommended to identify the distribution of high-pressure points along the plantar surface. However, as a preventive measure, it is suggested to encourage patients with diabetes and overweight or obesity to wear appropriate footwear and pressure-relief insoles to relieve high-pressure areas - often seen in these populations - to help prevent foot complications.

RESUMEN

Leukocyte- and platelet-rich fibrin (L-PRF), a by-product of centrifuged autologous whole blood, contains high concentrations of platelets, leukocytes, and fibrin (the latter spontaneously creating a strong 3-D network (a membrane)). L-PRF membranes possess several characteristics essential in wound healing, including a barrier function, an antibacterial and analgesic activity, and the release of growth factors enhancing tissue regeneration and neo-vasculogenesis. This review investigated the role of L-PRF in treating non-responding chronic wounds such as diabetic foot, venous leg ulcers, pressure ulcers, complex wounds, leprosy ulcers (Hansen's Disease), and other demanding wounds. Chronic wounds affect millions worldwide, negatively impacting their quality of life, productivity, and life expectancy while incurring high treatment costs for themselves and private and public health systems. L-PRF has demonstrated clear adjunctive advantages in treating chronic skin wounds, shortening the time to complete wound closure, and improving patient-reported outcome measures (including reducing pain and minimizing the need for analgesics). Also, in other demanding wounds, L-PRF facilitates healing. To help clinicians, this article also proposes recommendations for the use of L-PRF in the treatment of extra-oral wounds.

RESUMEN

Introducción: La úlcera del pie diabético es una de las principales complicaciones de los pacientes con diabetes, y se ha convertido en una causa importante de amputación no traumática. El 60 por ciento de las úlceras del pie diabético pueden infectarse con microorganismos y aumentar el riesgo de amputación en un 50 por ciento en comparación con pacientes con úlceras en los pies sin infección. La resistencia a los antimicrobianos (RAM) es un fenómeno mundial que ha alcanzado niveles alarmantes. Objetivo: Reportar un caso de un paciente que presentaba úlcera del pie diabético con infección por Acinetobacter lwoffii, al que se le realizó amputación de la extremidad por la multirresistencia del germen. Presentación de caso: Se presenta un caso de un paciente con diagnóstico de pie diabético neuroinfeccioso tipo absceso profundo. Al examen bacteriológico se constató presencia de Acinetobacter lwoffii resistente a casi todos los antibióticos excepto doxiciclina. El paciente requirió amputación de la extremidad como terapia definitiva de control de la sepsis. Conclusión: La evolución de este germen comenzó muy sensible a los antimicrobianos corrientes; después, tras rápida adaptación, devino primero resistente, luego multirresistente y ahora pandroga resistente, término acuñado exclusivamente para este tipo de germen(AU)

Introduction: Diabetic foot ulcer is one of the main complications of patients with diabetes and has become a major cause of non-traumatic amputation. 60 percent of diabetic foot ulcers can become infected with microorganisms, increasing the risk of amputation by 50 percent compared to patients with non-infected foot ulcers. Antimicrobial resistance is a global phenomenon that has reached alarming levels. Objective: To report a case of amputation of a patient with diabetic foot ulcer and Acinetobacter lwoffi infection. Case presentation: It is presented a case of a patient diagnosed with a deep abscess-type neuroinfectious diabetic foot. Bacteriological examination revealed the presence of Acinetobacter lwoffii resistant to almost all antibiotics, except doxycycline. The patient required amputation of the limb as definitive therapy to control sepsis. Conclusions: The evolution of this germ began very sensitive to common antimicrobials, but after a rapid adaptation, it became first resistant, then multidrug-resistant and then pandrug resistant, a term coined exclusively for this type of germ(AU)

RESUMEN

En el mundo un paciente diabético gasta entre dos y tres veces más que el no diabético. El pie diabético disminuye la calidad de vida, aumenta la morbimortalidad y la carga económica del sistema de salud. Objetivo: comunicar la investigación realizada sobre costos directos en el tratamiento de la úlcera del pie diabético. Material y método: estudio observacional, descriptivo, retrospectivo de pacientes asistidos en la Unidad de Pie del Hospital de Clínicas, Universidad de la República, entre octubre de 2014 y septiembre de 2016. Se estimaron gastos directos del tratamiento ambulatorio e internación a través de información de la historia clínica. El horizonte de tratamiento fue de tres meses. Se calcularon los gastos en unidades reajustables (UR), pesos y dólares. Los gastos se actualizaron a octubre del 2022 utilizando el índice de precios al consumo (IPC), ajustado a la tasa de inflación acumulada. Resultados: incluimos 49 pacientes, 11 mujeres y 38 hombres, edad promedio 61,5 años. El gasto general fue mayor a 400.000 dólares, con el mayor costo en gastos de internación. El gasto total promedio por paciente fue de 8.799 dólares. El tratamiento convencional fue 3.707,93 dólares, la amputación mayor 32.003,61 dólares y amputación menor 12.385,34 dólares. El gasto en internación fue muy superior al del paciente ambulatorio. En emergencia, 28 pacientes gastaron 4.396 dólares. El incremento de costos al año 2022 fue de 37,45%, suponiendo un gasto general de 16.682.993,4 pesos o 410.830,2 dólares. Conclusión: primera evaluación en nuestro país de estimación de gastos en pie diabético. El costo de la úlcera genera una carga económica notoria y en aumento. La gravedad inicial de la úlcera determina ingresos con elevados costes. Los gastos de internación y amputaciones representan la mayor erogación económica.

On a global scale, a diabetic patient incurs healthcare expenses that are 2 to 3 times higher than those of a non-diabetic individual. Diabetic foot syndrome reduces the quality of life, increases morbidity and mortality, and places an economic burden on the healthcare system. Objective: Communicating the research conducted on direct costs in the treatment of diabetic foot ulcers. Method: Observational, descriptive, retrospective study of patients treated at the Foot Unit of the Hospital de Clínicas (UDELAR) between October 2014 and September 2016. Direct treatment costs for outpatient care and hospitalization were estimated using information from the medical records. The treatment horizon extended over a period of 3 months. Expenses were calculated in readjustable units, Uruguayan pesos (UYU), and United States dollars (USD). Expenses were updated to October 2022 using the Consumer Price Index (IPC) adjusted for the cumulative inflation rate. Results: 49 patients were included in the study: 11 women and 38 men, average age was 61.5 years old. The overall expenditure exceeded 400,000 USD, with the highest cost attributed to hospitalization expenses. The average total expenditure per patient amounted to 8,799 USD. The cost of conventional treatment was 3,707.93 USD, major amputation represented USD 32,003.61, and minor amputation USD 12,385.34. Hospitalization expenses significantly exceeded those of outpatient care. In the emergency department, 28 patients spent USD 4,396. The increase in costs by the year 2022 amounted to 37.45%, resulting in a total expenditure of UYU 16,682,993.4 (Uruguayan pesos) or USD 410,830.2. Conclusions: It was the first assessment in our country to estimate diabetic foot costs. The cost of ulcer management imposes a significant and increasing economic burden. The initial severity of the ulcer results in hospitalization which implies high associated costs. Hospitalization and amputation costs constitute the most substantial economic expenditure.

Em todo o mundo, um paciente diabético gasta entre 2 e 3 vezes mais do que um paciente não diabético. O pé diabético reduz a qualidade de vida, aumenta a morbimortalidade e a carga económica no sistema de saúde. Objetivos: Comunicar os resultados da pesquisa realizada sobre os custos diretos no tratamento das úlceras do pé diabético. Materiais e métodos: Estudo observacional, descritivo e retrospectivo de pacientes atendidos na Unidade de Pie do Hospital de Clínicas (UDELAR), entre outubro de 2014 e setembro de 2016.

As despesas foram atualizadas para outubro de 2022 pelo Índice de Preços ao Consumidor (IPC) ajustado à inflação acumulada. Resultados: Foram incluídos 49 pacientes: 11 mulheres e 38 homens com idade média de 61,5 anos. A despesa global foi superior a US$ 400.000, com o maior custo em despesas de hospitalização. A despesa total média por paciente foi de US$ 8.799. Os custos por tratamento foram: Tratamento convencional US$ 3.707,93 USD, amputação maior US$ 32.003,61 e amputação menor US$ 12.385,34. O gasto com internação foi muito superior ao do ambulatório. No atendimento de emergência 28 pacientes gastaram US$ 4.396. O aumento dos custos até 2022 foi de 37,45%, assumindo uma despesa geral de UY$ 16.682.993,4 ou US$ 410.830,2 USD. Conclusão: Esta é a primeira avaliação de estimativa de gastos com pé diabético realizada no Uruguai. O custo das úlceras gera uma carga económica notável e crescente. A gravidade inicial da úlcera determina internações com custos elevados. As despesas com hospitalização e amputação representam o maior gasto financeiro.

RESUMEN

Diabetic foot ulcers (DFU) are exacerbated by bacterial colonisation. Here, a high prevalence of Enterococcus faecalis was observed in DFU patients from an Argentinean hospital. E. faecalis was frequently co-isolated with Escherichia coli, Morganella morganii, and Pseudomonas aeruginosa. The effect of interspecies interactions on bacterial growth was investigated in mixed-species macrocolony biofilms developed in Lubbock-Glc-agar. Similar cell counts were found for E. faecalis and M. morganii growing in mixed and single-species biofilms. An E. faecalis strain showed 1 Log higher cell counts in mixed biofilms with E. coli. Remarkably, E. faecalis strains showed 2 to 4 Log higher cell counts in mixed biofilms with P. aeruginosa. This effect was not observed in planktonic growth or biofilms developed in tryptic soy agar. The present findings reveal bacterial interactions that benefit E. faecalis in mixed-species biofilms, mainly with P. aeruginosa, in a medium that partially mimics the nutrients found in DFU.

RESUMEN

An impaired healing response underlies diabetic foot wound chronicity, frequently translating to amputation, disability, and mortality. Diabetics suffer from underappreciated episodes of post-epithelization ulcer recurrence. Recurrence epidemiological data are alarmingly high, so the ulcer is considered in "remission" and not healed from the time it remains epithelialized. Recurrence may result from the combined effects of behavioral and endogenous biological factors. Although the damaging role of behavioral, clinical predisposing factors is undebatable, it still remains elusive in the identification of endogenous biological culprits that may prime the residual scar tissue for recurrence. Furthermore, the event of ulcer recurrence still waits for the identification of a molecular predictor. We propose that ulcer recurrence is deeply impinged by chronic hyperglycemia and its downstream biological effectors, which originate epigenetic drivers that enforce abnormal pathologic phenotypes to dermal fibroblasts and keratinocytes as memory cells. Hyperglycemia-derived cytotoxic reactants accumulate and modify dermal proteins, reduce scar tissue mechanical tolerance, and disrupt fibroblast-secretory activity. Accordingly, the combination of epigenetic and local and systemic cytotoxic signalers induce the onset of "at-risk phenotypes" such as premature skin cell aging, dysmetabolism, inflammatory, pro-degradative, and oxidative programs that may ultimately converge to scar cell demise. Post-epithelialization recurrence rate data are missing in clinical studies of reputed ulcer healing therapies during follow-up periods. Intra-ulcer infiltration of epidermal growth factor exhibits the most consistent remission data with the lowest recurrences during 12-month follow-up. Recurrence data should be regarded as a valuable clinical endpoint during the investigational period for each emergent healing candidate.

RESUMEN

Introducción: El plasma rico en plaquetas (PRP) se encuentra en desarrollo desde los años 80, asociado con aplicaciones en medicina cardíaca, traumatológica y dermatológica. El PRP es una preparación autóloga, con una concentración de plaquetas por sobre el valor normal en sangre periférica, que se obtiene a partir de su centrifugación siguiendo diferentes protocolos que fueron valorados en distintas revisiones sistemáticas. El plasma luego se activa con trombina o cloruro cálcico, o por lisis física (ultrasonido o frizado). El PRP contiene factores de crecimiento, citoquinas y proteínas de adhesión que, al aplicarse en la lesión, favorecen la hemostasia, la síntesis de tejido conectivo y la revascularización. El producto se aplica en solución o gel. Se intentaron diferentes clasificaciones del PRP para estandarizarlo, sin éxito. Se conceptualizó la receta del PRP para aplicación clínica, que presentó las siguientes características: valores altos de plaquetas, disminución de la contaminación de glóbulos rojos, presencia de neutrófilos y leucocitos para el éxito terapéutico. Protocolo y casos: Se presenta el protocolo de preparación de PRP de centrifugación única de 7 minutos a 1400 rpm, con activación por medio de gluconato de calcio según la siguiente proporción: 3 ml plasma/0.4 ml gluconato cálcico. Además, se informan tres casos de úlceras de pie diabético de nuestra institución. Conclusión: El PRP no presenta complejidad en su preparación y aplicación, por lo que es factible de realizar en el primer nivel de atención que cuente con los recursos materiales y profesionales con conocimiento en el abordaje de heridas crónicas.

Introduction: Platelet-rich plasma (PRP) has been under development since the 1980s, associated with applications in cardiac, traumatological, and dermatological medicine. PRP is an autologous preparation with a platelet concentration above the normal value in peripheral blood that is obtained from its centrifugation following different protocols that were evaluated in different systematic reviews. The plasma is then activated with thrombin or calcium chloride, or by physical lysis (ultrasound or friz). PRP contains growth factors, cytokines, and adhesion proteins that, when applied to the lesion, favor hemostasis, connective tissue synthesis, and revascularization. The product is applied in solution or gel. Different classifications of the PRP were used with the intention of standardizing the procedure without success. The PRP recipe for clinical application was conceptualized. It presented the following characteristics: high platelet values, decreased red blood cell contamination, presence of neutrophils and leukocytes for therapeutic success. Protocol and cases: The PRP preparation protocol for single centrifugation for 7 minutes at 1400 rpm with activation through calcium gluconate is presented according to the following ratio: 3 ml plasma/0.4 ml of calcium gluconate. Three cases of diabetic foot ulcers from our institution are reported. Conclusion: The PRP does not present complexity in its preparation and application, so it is feasible to perform it in the first level of care that has the material and professional resources with knowledge in the approach to chronic wounds.

RESUMEN

Dentre as Doenças Crônicas não Transmissíveis (DCNT), o Diabetes Mellitus (DM) se destaca por sua constante ascensão e taxas de morbimortalidade e aos altos custos sociais, econômicos e psicológicos. Ainda, quando não controlado o DM, propicia o desenvolvimento de complicações altamente incapacitantes, destacando-se as úlceras ou infecções em membros inferiores o que conhecemos como "pé diabético". O objetivo do estudo foi identificar as ações preventivas para úlceras ou infecções em membros inferiores em pessoas com diabetes mellitus realizadas pelos enfermeiros nas equipes de Saúde da Família. Além disso, realizar um produto tecnológico como elaborar um roteiro de rastreamento para úlceras ou infecções em membros inferiores para as pessoas com diabetes mellitus. Pesquisa de abordagem qualitativa realizada com 24 enfermeiros de equipes de saúde da família (eSF) do município de Passos - Minas Gerais. Foram incluídos no estudo os enfermeiros que atuam diretamente na assistência por mais de seis meses e excluídos aqueles que estivessem em cargo de gestão, de férias ou afastados por algum motivo. As entrevistas foram realizadas nas unidades de saúde por meio de um roteiro de perguntas para identificação de conhecimentos acerca da temática. As entrevistas foram audiogravadas e transcritas e analisadas pela técnica de análise temática e discutidas pela literatura científica. Dos 24 enfermeiros que atuam nas eSF, 12,5% eram do sexo masculino e 87,5% do sexo feminino. Apenas 16,6% dos entrevistados possuíam curso sobre o cuidado para pessoa com DM e apresentaram conhecimento limitado sobre a temática das úlceras ou infecções de membros inferiores. As ações de cuidado voltam-se para o controle glicêmico e avaliação da medicação para atendimento do hiperdia. Em relação as práticas preventivas as orientações realizadas versam sobre os cuidados gerais de higiene, uso de calçados, corte das unhas e tratamento local de feridas. Pouco se realiza na consulta de enfermagem a avaliação clínica para o risco de úlceras ou infecções em membros inferiores. Acerca dos recursos que o município dispõe para o atendimento à pessoa com úlceras ou infecções em membros inferiores evidencia-se que o município não dispõe de uma local de referência para o tratamento da diabetes e que o serviço especializado é bastante demorado e falta recursos humanos e materiais. Portanto, destaca-se a necessidade da promoção da educação continuada e permanente como ferramenta para que possa ter conhecimentos e habilidades, bem como, discutir sobre o processo de trabalho para proporcionar cuidados efetivos com conhecimento baseado em evidências. Além disso, é preciso investimentos para qualificar a consulta de enfermagem à pessoa com DM e as práticas preventivas, especialmente, as voltadas para o risco de desenvolvimento de úlceras ou infecções em membros inferiores. No intuito de colaborar para a melhoria das práticas preventivas e identificação de risco no processo de trabalho dos enfermeiros, foi elaborado um roteiro de rastreamento para úlceras ou infecções em membros inferiores para que os enfermeiros possam utilizar nas consultas às pessoas com DM

Among Chronic Noncommunicable Diseases (NCDs), Diabetes Mellitus (DM) stands out for its constant rise and morbidity and mortality rates and the high social, economic and psychological costs. Still, when DM is not controlled, it favors the development of highly disabling complications, especially ulcers or infections in the lower limbs, what we know as "diabetic foot". The objective of the study was to identify preventive actions for ulcers or infections in the lower limbs in people with diabetes mellitus carried out by nurses in the Family Health teams. In addition, making a technological product such as developing a screening script for ulcers or infections in the lower limbs for people with diabetes mellitus. Qualitative research carried out with 24 nurses from family health teams (eSF) in the city of Passos - Minas Gerais. Nurses who work directly in care for more than six months were included in the study, and those who were in management positions, on vacation or on leave for some reason were excluded. The interviews were carried out in the health units through a script of questions to identify knowledge about the theme. The interviews were audio-recorded and transcribed and analyzed using the thematic analysis technique and discussed in the scientific literature. Of the 24 nurses working in the eSF, 12.5% were male and 87.5% were female. Only 16.6% of respondents had taken a course on care for people with DM and had limited knowledge on the subject of ulcers or lower limb infections. Care actions focus on glycemic control and assessment of medication for hyperdia treatment. Regarding preventive practices, the guidelines provided deal with general hygiene care, use of shoes, nail trimming and local treatment of wounds. Little is done in the nursing consultation regarding the clinical assessment of the risk of ulcers or infections in the lower limbs. Regarding the resources that the municipality has for the care of people with ulcers or infections in the lower limbs, it is evident that the municipality does not have a reference place for the treatment of diabetes and that the specialized service is quite time consuming and lacks human resources and materials. Therefore, there is a need to promote continuing and permanent education as a tool to acquire knowledge and skills, as well as to discuss the work process to provide effective care with evidence-based knowledge. In addition, investments are needed to qualify the nursing consultation for people with DM and preventive practices, especially those aimed at the risk of developing ulcers or infections in the lower limbs In order to contribute to the improvement of preventive practices and risk identification in the work process of nurses, a screening script for ulcers or infections in the lower limbs was elaborated so that nurses can use it in consultations with people with DM

Introduction: Diabetic foot ulcer is one of the main causes of morbidity and disability, with an important repercussion due to the economic burden of the disease and from the social point of view, due to the decrease in patients' quality of life. Objective: To assess costs and outcomes of outpatient treatment with Heberpro-P® for the care of patients with diabetic foot ulcers. Methods: A descriptive, longitudinal and retrospective study was carried out of 22 patients with diabetic foot treated with Heberprot-P®, in the consultation for such purposes of Ramón López Peña Polyclinic in 2019. Results: 63.6 percent of the patients who came for consultation presented zero risk foot; neuroinfectious ulcer was the one with the highest incidence of presentation (94.5 percent). An effectiveness rate of 95.4 percent of the total of treated cases was obtained. Most of those treated needed three to eight bulbs of the medication, with an average of five treatment sessions per patient, at an average cost of 3549.8 Cuban pesos per treated case. Conclusions: Treatment with Heberprot-P® is highly effective for the healing of diabetic foot ulcers, largely avoiding amputations of lower limbs of patients with diabetes mellitus, with a consequent decrease in the economic cost of these health interventions for the country(AU)

RESUMEN

BACKGROUND: Diabetic foot ulcers (DFU) are characterised by high levels of inflammatory mediators, resulting from sustained hyperglycaemic insult and the local microbial biofilm. The intralesional administration of epidermal growth factor (EGF) has emerged as an effective treatment that stimulates granulation and closure of DFU, reducing the risk of amputation. Within the wound, fibroblasts play key roles during the healing process, promoting granulation and contraction. The aim of the present study was to examine the anti-inflammatory effect of EGF in DFU-derived fibroblasts, challenged with lipopolysaccharide (LPS), under hyperglycaemic conditions, recreating in vitro what happens in a clinical scenario. METHODS: Healthy skin (HS) and DFU granulation tissue biopsies were used to isolate primary fibroblasts. The effect of LPS on cell proliferation was analysed. Transcriptional expression of toll-like receptor (TLR) pathway mediators (TLR4, TLR2, CD14, MYD88 and NFKB) and pro-inflammatory cytokines (TNF, IL-6 and IL-1B) were measured by semi-quantitative polymerase chain reaction (qPCR), in cells treated with appropriate concentrations of LPS, EGF and their combination. IL-6 protein concentration was quantified by ELISA. RESULTS: LPS stimulated proliferation of HS-derived fibroblasts, while inhibiting the proliferation of cells derived from DFU at the highest assayed concentration of 1 µg/mL. Regarding the TLR signalling pathway, LPS increased messenger RNA levels of mediators and pro-inflammatory genes, while EGF, alone or in the presence of LPS, downregulated them, except for IL-1B. CONCLUSION: The results suggest that EGF might elicit an anti-inflammatory response in LPS-challenged fibroblasts, even in a hyperglycaemic milieu. Collectively, our findings contribute to explain newly observed effects of EGF in the clinical arena. LAY SUMMARY: In this research article, we analyse the putative anti-inflammatory effect of epidermal growth factor (EGF) on fibroblast isolated from diabetic foot ulcer (DFU) granulation tissue. To induce the inflammatory response, the cells were treated with lipopolysaccharide (LPS), simulating the gram-negative bacterial infection that takes place in the wounds of diabetic patients. We studied the expression of genes involved in bacterial recognition receptors signalling pathway and those that code for different pro-inflammatory cytokines.We obtained primary fibroblasts from biopsies of a neuropathic diabetic ulcer and from healthy skin, the former was used as the control. Cells were isolated and grown in high glucose Dulbecco's Modified Eagle Medium (DMEM) culture medium, to simulate the hyperglycaemic insult. The effect of increasing concentrations of LPS on cell proliferation was analysed. Relative transcriptional expression of genes in the study was quantified by quantitative polymerase chain reaction (qPCR) in cells treated with LPS, EGF or a combination. Untreated cells served to normalise the expression.In the present study, we demonstrated that EGF modulated the primary immune response by reducing the activation of pathogen-recognition receptors and common genes involved in these signalling pathways, even in hyperglycaemic conditions. This effect translated in a decreased expression of pro-inflammatory cytokines. These results contribute to explain our previous observations about the reduction of circulating levels of inflammatory cytokines after local administration of human recombinant EGF in DFU. Further molecular studies should be carried out to fully understand the biological mechanisms elicited by EGF in this clinical scenario.

RESUMEN

Background: Diabetic foot ulcer is one of the frequent complications of diabetes. 15% to 25% develop ulcers at some point in their lives. The existing evidence on the efficacy of topical autologous platelet-rich plasma (PRP) for the treatment of diabetic foot ulcers was assessed. Method: A search for randomized controlled clinical trials comparing autologous topical PRP vs standard care and placebo was carried out in Pubmed, Cochrane, Lilacs, and Clinical Trials databases. For dichotomous outcomes, relative risk analysis, 95% CI, and the Mantel-Haenszel method were used; for continuous outcomes, the mean difference and inverse variance method were calculated. Results: The result of the search was 153 studies, 28 duplicates were excluded, 59 by title and abstract, and 52 by reading the article. 14 studies were included in the review, 8 for qualitative review and 6 for quantitative. Six studies with a complete ulcer-healing outcome at the end of the intervention were evaluated, out of a total of 415 participants (relative risk 1.24 CI [1.11, 1.40]). The outcome epithelialized area at the end of the intervention, measured in cm², was not reported. A single study measured quality of life and pain. Conclusion: There is evidence of the beneficial effect of topical autologous PRP for the healing of diabetic foot ulcers, however, studies of higher methodological quality, greater production of clinical trials in Latin America, and assessment of the quality of life and pain are needed.

Antecedentes: La úlcera de pie diabético constituye una de las complicaciones frecuentes de la diabetes. Del 15% al 25% de los pacientes presentan úlceras en algún momento de su vida. Se valoró la evidencia existente sobre la eficacia del plasma rico en plaquetas (PRP) autólogo tópico para el tratamiento de úlcera de pie diabético. Método: Se llevó a cabo a partir de datos de Pubmed, Cochrane, Lilacs y Clinical Trials, búsqueda de ensayos clínicos aleatorizados controlados que compararon PRP autólogo tópico frente a cuidados estándar y placebo. Para los resultados dicotómicos se usó el análisis de riesgo relativo, con intervalos de confianza del 95% y el método de Mantel-Haenszel; para los resultados continuos, se calculó la diferencia de medias y método de varianza inversa. Resultados: El resultado de la búsqueda fue 153 estudios, se excluyeron 28 duplicados, 59 por título y abstract y 52 por lectura de artículo. Se incluyeron 14 trabajos en la revisión, 8 para revisión cualitativa y 6 para cuantitativa. Se valoraron 6 estudios con desenlace de curación completa de úlcera al final de la intervención, sobre un total de 415 participantes (riesgo relativo 1.24 [IC 95%: 1.11 a 1.40]). No se informó el desenlace área epitelizada al final de la intervención medida en cm². Un solo estudio midió calidad de vida y dolor. Conclusión: Existe evidencia del efecto beneficioso del PRP autólogo tópico para la curación de úlcera de pie diabético; no obstante, se necesitan estudios de mayor calidad metodológica, mayor producción de ensayos clínicos en Latinoamérica y valoración de calidad de vida y dolor.

RESUMEN

Abstract Chronic type 2 diabetes mellitus (T2DM) and its associated diseases are major concern among human population and also responsible for significant mortality rate. Hence, the present study aims to evaluate and correlate the invertase inhibition, antioxidant activity and control against DFU causing bacterial pathogens by Pandanus odoratissimus flowers. Two dimensional preparative thin layer chromatography (2D PTLC) was adopted to purify the phenolic acid component and LC-MS2 was done to predict the phenolic acid structures. Standard spectrophotometry methods were adopted to investigate the in vitro invertase inhibitory and antioxidant (CUPRAC and ABTS) activities. Agar well diffusion and broth dilution assays were used to record the antibacterial property against DFU causing pathogens isolated from clinical samples. Statistical analyses were used to validate the experiments. A new and novel diferuloyl glycerate related phenolic acid (m/z 442) purified from PTLC eluate has recorded satisfactory cupric ion reducing power (ED50= 441.4±2.5 µg), moderate ABTS radical scavenging activity (IC50= 450.3±10 µg; 32.5±1.5%), and a near moderate, in vitro, invertase mixed type inhibition (24.5±4.5%; Ki: 400 µg). Similarly, bacterial growth inhibitory kinetics has showed a significant inhibition against E. coli and S. aureus.

RESUMEN

RESUMEN Introducción: Las infecciones de las úlceras del pie diabético son comunes, complejas, de alto costo y constituyen la principal causa de amputación no traumática de las extremidades inferiores. Objetivo: Identificar los microorganismos aislados para estimar tanto la sensibilidad a los antibióticos como la coincidencia entre el tratamiento empírico y los resultados microbiológicos en pacientes con úlceras del pie diabético. Métodos: Se realizó una investigación descriptiva-retrospectiva. La población de estudio estuvo constituida por 210 pacientes ingresados en el Hospital Universitario Clínico Quirúrgico "Comandante Faustino Pérez Hernández" de Matanzas entre junio de 2017 y junio de 2020. Las variables de salida fueron la frecuencia y el tipo de germen, la cantidad de gérmenes por úlcera, la sensibilidad para cada tipo de antibiótico, y el porcentaje de coincidencia entre el tratamiento empírico y el resultado microbiológico. Resultados: Se identificaron 259 gérmenes y se observaron 1,23 gérmenes por úlcera. El 62,5 por ciento de los gérmenes encontrados fueron Gram negativos, pero el germen más representado fue el Staphylococcus aureus. El 58,8 por ciento de los Staphylococcus aureus se mostraron resistentes a la meticillin. La vancomicina y el linezolid resultaron efectivos en el 100 por ciento de los Gram positivos. La amikacina fue el antibiótico más efectivo para los Gram negativos. Se observó coincidencia entre el tratamiento empírico y el resultado del antibiograma en el 27,6 por ciento de los pacientes. Conclusiones: Resulta necesario un apropiado diagnóstico microbiológico de las úlceras del pie diabético para identificar los gérmenes presentes en las lesiones y diseñar algoritmos de terapia antimicrobiana adecuados(AU)

ABSTRACT Introduction: Diabetic foot ulcer infections are common, complex, high cost and are the leading cause of non-traumatic lower extremity amputation. Objective: To identify the microorganisms isolated to estimate both the sensitivity to antibiotics and the coincidence between empirical treatment and microbiological results in patients with diabetic foot ulcers. Methods: A descriptive-retrospective investigation was performed. The study population consisted of 210 patients admitted to the University Hospital "Comandante Faustino Pérez Hernández" of Matanzas between June 2017 and June 2020. The output variables were the frequency and type of germ, the number of germs per ulcer, the sensitivity for each type of antibiotic, and the percentage of coincidence between the empirical treatment and the microbiological result. Results: A total of 259 germs were identified and 1.23 germs per ulcer were observed. The 62.5 percent of the germs found were Gram negative, but the most represented germ was Staphylococcus aureus. Of the Staphylococcus aureus, 58.8 percentwere resistant to methicillin. Vancomycin and linezolid were effective in 100 percent of Gram positives. Amikacin was the most effective antibiotic for Gram-negatives. Agreement between empirical treatment and antibiogram result was observed in 27.6 percent of patients. Conclusions: An appropriate microbiological diagnosis of diabetic foot ulcers is necessary to identify the germs present in the lesions and to design adequate antimicrobial therapy algorithms(AU)

RESUMEN

Globally, the prevalence of diabetes has risen significantly by 62% over the last ten years. A complication of unmanaged diabetes is diabetic foot ulcer (DFU), which adversely affects the quality of life of individuals with diabetes and inflicts a huge economic burden on the family, government, and health care services. However, this complication is preventable with adequate patient knowledge and practice regarding DFU and foot care. The present study was aimed at assessing the knowledge, attitude, and practice of adults with diabetes on foot ulcers and foot care in Tobago using a qualitative exploratory design. Purposeful sampling technique was used to recruit 20 participants from the lifestyle and diabetes foot clinics of Scarborough Health Centre, Tobago. Telephone interviews were conducted with the use of a semi-structured interview guide. The data obtained from participants were analyzed using thematic content analysis. Four major themes, namely foot ulcer problems, participants' knowledge on DFU, knowledge on foot care, and practice and attitude of foot care, emerged from the study. The findings from the study revealed that the majority of participants had poor knowledge regarding DFU but exhibited awareness about foot care, especially on foot cleaning and inspection, preventing irritation after washing, appropriate footwear, and not walking barefooted. The participants had good attitudes and practices of foot care despite their poor knowledge of DFU. However, participants reported inadequate health education on DFU and foot care from healthcare personnel. There should be improved health education, information, and communication on DFU and foot care centred and tailored to the understanding of people living with diabetes. This will prevent DFU and reduce the mortality arising from this complication, which is a major target of the sustainable development goals (SDG) in mitigating the burden of non-communicable diseases (NCD) such as diabetes.

RESUMEN

Introducción: Las úlceras del pie diabético resultan las complicaciones más frecuentes en las personas con diabetes. Se conocen diferentes formas de tratamiento para esta enfermedad, con más o menos efectividad, pero no resuelven el problema en la totalidad de los casos. El estimulador eléctrico Stimul W® y el medicamento Heberprot-P® se han empleado, de manera independiente y con resultados satisfactorios, como alternativas para el tratamiento de estas lesiones. Comprobar si la acción combinada de ambos procedimientos permite alcanzar mejores resultados, permitiría contribuir a resolver un problema de alta prevalencia mundial. Objetivo: Exponer el resultado de la aplicación de la combinación del estimulador Stimul W® y el medicamento Heberprot-P® en el tratamiento de un paciente con úlcera del pie diabético. Presentación del caso: Paciente masculino de 69 años de edad, con diabetes mellitus de tipo 2, que presentaba una úlcera del pie diabético en la parte externa del pie derecho, con abundante tejido necrótico en forma de fístula en la base de los dos dedos restantes y falta de granulación. Los tratamientos anteriores no dieron el resultado esperado. Se decidió, como terapia de curación, aplicar durante 12 sesiones la combinación del estimulador Stimul W® y el medicamento Heberprot-P®. Conclusiones: Se logró la cicatrización de la lesión, al obtener un 100 por ciento de tejido de granulación y la disminución significativa de sus dimensiones, lo que mostró que la terapia aplicada constituye una alternativa para el tratamiento de este tipo de úlcera(AU)

Introduction: Diabetic foot ulcers are the most frequent complications in people with diabetes. Different forms of treatment for this disease are known, with more or less effectiveness; but they do not solve the problem in all cases. The electrical stimulator Stimul W® and the drug Heberprot-P® have been used independently, and with satisfactory outcomes, as alternatives for the treatment of these lesions. Checking whether the combined action of both procedures allows to achieve better outcomes would contribute to solve a problem of high worldwide prevalence. Objective: To present the outcomes of applying the combination of the stimulator Stimul W® and the drug Heberprot-P® for treating a patient with diabetic foot ulcer. Case presentation: A 69-year-old male patient, with type 2 diabetes mellitus, who presented with a diabetic foot ulcer on the outside of the right foot, with abundant necrotic tissue in the form of a fistula at the base of the two remaining toes and lack of granulation. The previous treatments did not permit the expected outcomes. It was decided, as a healing therapy, to apply the combination of the stimulator Stimul W® and the drug Heberprot-P® for twelve sessions. Conclusions: Healing of the lesion was achieved by obtaining 100 percent granulation tissue and a significant reduction in its dimensions, which showed that the applied therapy constitutes an alternative for the treatment of this type of ulcer(AU)

RESUMEN

OBJECTIVE: To evaluate the burden of diabetic foot complications amongst inpatients in Peru. MATERIALS AND METHODS: Cross-sectional multicenter study, performed in public hospitals, in one-day enrollment between October and December 2018. RESULTS: We included 8346 patients from 39 national hospitals. Diabetic foot (DF) inpatient point prevalence was 2.8% (CI 95% 2.4-3.1), and DF point prevalence among Diabetes Mellitus (DM) inpatients was 18.9% (CI 95% 16.7-21.1). DF prevalence was higher in jungle and coastal hospitals than highlands ones, and there was no difference according to its care complexity level. Of the 234 patients with DF, 73% were males, age average was 62 ± 12 years, with DM mean time duration of 15 ± 9.9 years. Regarding to DF etiology, 91% and 68% had some degree of peripheral neuropathy and peripheral artery disease, respectively. According to the Infectious Diseases Society of America criteria, 61% presented moderate to severe infections, and 40% had bone involvement. Debridement within 48 h was performed in 36% of sepsis cases. CONCLUSION: Peru has a substantial burden of DF disease, with a greater share of that burden falling on less equipped hospitals in the country's jungle and coastal regions. Interdisciplinary teams and pathways may improve the time of surgical debridement in the highest risk patients.

RESUMEN

Lower limb ulcers in type-2 diabetic patients are a frequent complication that tributes to amputation and reduces survival. We hypothesized that diabetic healing impairment and other histopathologic hallmarks are mediated by a T2DM-induced tissue priming/metabolic memory that can be transferred from humans to healthy recipient animals and consequently reproduce diabetic donor's phenotypes. We examined the effect of human T2DM tissue homogenates injected into non-diabetic rat excisional wounds. Fresh granulation tissue, popliteal artery, and peroneal nerve of patients with T2DM were obtained following amputation. Post-mammoplasty granulation and post-traumatic amputation-tissue of normal subjects acted as controls. The homogenates were intralesionally injected for 6-7 days into rats' excisional thickness wounds. Infiltration with the different homogenates caused impaired wound closure, inflammation, nerve degeneration, and arterial thickening (all P < 0.01 vs relevant control) resembling histopathology of diabetic donor tissues. Control materials caused marginal inflammation only. Infiltration with glycated bovine albumin provoked inflammation and wound healing delay but did not induce arterial thickening. The reproduction of human diabetic traits in healthy recipient animals through a tissue homogenate support the notion on the existence of tissue metabolic memory-associated and transmissible factors, involved in the pathogenesis of diabetic complications. These may have futuristic clinical implications for medical interventions.

RESUMEN

Diabetic foot ulcers (DFUs) are considered one of the most aggressive and expensive complications of diabetes. Low-level laser therapy (LLLT) has been highlighted as a potential modality of treatment to accelerate the healing of ulcers. This systematic review and meta-analysis aimed to investigate the efficacy of LLLT in the treatment of DFU and identify the LLLT application parameters recommended for the treatment of DFU over the past 10 years. A systematic search was conducted in PubMed, BVS, PEDro, Scopus, Web of Science, and CINAHL up to March 31, 2019. Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, randomized controlled trials (RCTs) that assessed the effect of LLLT on the treatment of DFU were included. Thirteen RCTs with a total of 361 participants were included in this review. Three RCTs reported a reduction in the percentage size of the ulcers and were included in the meta-analysis. The meta-analysis of the percentage size difference demonstrated a significant reduction in ulcer size in the LLLT group compared with controls (22.96 [95% confidence interval = 18.22-27.69; z = 9.51, P < .0001]). Treatment with 632.8 to 685 nm, 50 mW/cm2, 3 to 6 J/cm2, and irradiation for 30 to 80 seconds, 3 times weekly for a month is of benefit to patients with DFU. LLLT is effective and safe for the treatment of DFU. Additionally, well-designed, high-quality studies are needed to allow its ideal parameterization for clinical practice.
