    Analyses of transcutaneous oxygen pressure values stratified for foot angiosomes to predict diabetic foot ulcer healing
    (Elsevier, 2023-10-08) López-Moral M; García-Madrid Martín De Almagro, Marta; Molines Barroso, Raúl Juan; García Álvarez, Yolanda; Tardaguila García, Aroa; Lázaro Martínez, José Luis; Elsevier
    Aims: Previous research suggested that diabetic foot ulcer (DFU) location could affect transcutaneous oxygen pressure (TcPO2) values following the angiosome concept. Up to our knowledge no studies have yet analyzed if the location of a diabetic foot ulcer can be a confounding factor that modifies TcPO2 values. The primary aim of this study was to compare the potential healing prognosis of TcPO2 differentiated for diabetic foot ulcers in different angiosome locations. Methods: a 2-years observational cohort prospective study was performed in 81 patients with diabetic foot ulcers. Transcutaneous oxygen pressure measurements were performed at baseline by placing the electrode on two different angiosomes: dorsal zone of the foot (dorsalis pedis angiosome) and between the navicular bone and the tibial malleolus (posterior tibial angiosome). The main outcome was establishing the effectiveness of TcPO2 measurements (dorsalis pedis angiosome and posterior tibial angiosome) for predicting DFU healing. Results: Transcutaneous oxygen pressure probe placed in the dorsum of the foot (dorsalis pedis angiosome) yielded a sensitivity (S) of 95 % and specificity (SP) of 73 %, and an area under the curve (AUC) of 0.902 (p < 0.001 [0.84–0.96]) for ulcers located in the forefoot and toes; while TcPO2 placed in the posterior tibial angiosome yielded an S of 100 % and SP of 85 % and an AUC of 0.894 (p <0.001 [0-822-0.966]) for DFU located in the midfoot and heel. Conclusion: This study suggests that angiosome-guided TcPO2 contributes to a prognosis of successful foot ulcer healing.

    Metalloproteinases in chronic and acute wounds: A systematic review and meta-analysis
    (Wiley-Blackwell, 2019-03-19) Tardaguila García, Aroa; García Morales, Esther Alicia; García Alamino, Josep María; Álvaro Afonso, Francisco Javier; Molines Barroso, Raúl Juan; Lázaro Martínez, José Luis
    A systematic review and meta-analysis were undertaken in order to explore the influence of matrix metalloproteinases and their diagnostic methods in chronic and acute wounds. Searches were conducted in the PubMed (Medline) and Embase (Elsevier) databases from inception to late November 2017. We included clinical trials enrolling patients with cutaneous chronic and acute wounds where a validated diagnostic method was employed for metalloproteinases. We excluded in vitro, animal or preclinical studies, nonoriginal articles, and studies without available data for analysis. In addition, references of narrative and systematic reviews were scrutinized for additional articles. Eight studies met the inclusion criteria. Results revealed that the most frequently determined matrix metalloproteinases were MMP-2 and MMP-9, and were found in 54.5% of wounds. MMP-9 was present in more than 50% of the chronic wounds with a range from 37 to 78%. However, metalloproteinases were found in only 20% of acute wounds, and other types of metalloproteinases were also observed (MMP-2 and MMP-3). On the basis of the available evidence, high levels of metalloproteinases have been correlated with significantly delayed wound healing in wounds of a variety of etiologies.

    Correlation between Empirical Antibiotic Therapy and Bone Culture Results in Patients with Osteomyelitis
    (Lippincott Williams & Wilkins, 2019-01) Tardaguila García, Aroa; Lázaro Martínez, José Luis; Sanz Corbalán, Irene; García Álvarez, Yolanda; Álvaro Afonso, Francisco Javier; García Morales, Esther Alicia
    Objective: To analyze the correlation between empirical antibiotic therapies prescribed in primary care centers by general practitioners and the microbiology results of bone culture in patients with diabetic foot-related osteomyelitis. Methods: This observational study involved 80 patients with diabetic foot ulcers and clinically suspected osteomyelitis. The patients were taking antibiotics prescribed by general practitioners to treat diabetic foot infections. Bone samples were taken from every patient for microbiology analysis in a specialized diabetic foot unit. Main outcome measure: The sensitivity of the bone cultures to antibiotics was compared with the patient's previous antibiotic therapy, and antibiotic and bacterial resistance were analyzed. Main results: The bone cultures from only 16 patients (22.3%) showed sensitivity to the antibiotics that the patient had been prescribed. Fifty-six patients (77.8%) displayed bacterial resistance to the antibiotic that they were taking. Conclusions: Awareness and implementation of international antibiotic stewardship guidelines are poor in primary care centers. It is important to establish strategies that foster a better understanding of treatment management standards and ensure the proper implementation of guidelines.

    Microbiological culture combined with PCR for the diagnosis of onychomycosis: Descriptive analysis of 121 patients
    (Wiley-Blackwell, 2023-08-13) Navarro Pérez, David; García Oreja, Sara; Tardaguila García, Aroa; León Herce, Diego; Álvaro Afonso, Francisco Javier; Lázaro Martínez, José Luis
    Background: Onychomycosis is the most common nail pathology, involving various pathogens such as dermatophytes, moulds and yeasts. Objective: The objective of this study was to observe the prevalence of onychomycosis, analyse the most appropriate diagnostic test, and assess the distribution of pathogens based on age, sex, quarter of the year, duration of symptoms and previous treatment. Methods: Retrospectively, mycological culture and PCR data and results were collected from 121 patients. Results: Of the 121 samples, 57% (69/121) tested positive when both microbiological study techniques were combined. The prevalence of onychomycosis was higher when PCR was performed (52.1%) compared to microbiological culture (33.1%). Among the 81 samples negative by microbiological culture, 31 were positive by PCR. Similarly, of the 58 samples negative by PCR, eight were positive by microbiological culture. Diagnostic accuracy data (with 95% confidence intervals) for PCR, using microbiological culture as the gold standard, were as follows: sensitivity of 0.8, specificity of 0.62, positive predictive value of 0.51 and negative predictive value of 0.86. The most frequently identified pathogen was Trichophyton rubrum, and the hallux nail plate was the most commonly affected location. However, no statistically significant associations were found between sex, age, quarter of the year and affected area with culture and PCR results. Conclusion: Combining microbiological culture and PCR can increase the detection rate of onychomycosis and help avoid false-negative results.

    A comparison of hyperspectral imaging with routine vascular noninvasive techniques to assess the healing prognosis in patients with diabetic foot ulcers
    (Elsevier, 2022-01) López Moral, Mateo; García Álvarez, Yolanda; Molines Barroso, Raúl Juan; Tardaguila García, Aroa; García-Madrid Martín De Almagro, Marta; Lázaro Martínez, José Luis
    Objective: To compare the potential healing prognosis of the different routine noninvasive techniques implemented in the International Working Group Diabetic Foot Guidelines with the novel use of hyperspectral imaging (HSI) in patients with diabetic foot ulcers (DFUs). Methods: Twenty-one patients with active DFUs participated in this 1-year prospective study in a specialized diabetic foot unit between December 2018 and January 2020. HSI was performed at baseline to quantify tissue oxygenation and should be presented on an anatomical map by analyzing the following parameters: (1) oxygen saturation of the hemoglobin, (2) tissue hemoglobin index, (3) the near-infrared perfusion index, and (4) tissue water index. In addition, transcutaneous oxygen pressure (TcpO2), systolic toe and ankle pressures, ankle-brachial index, and toe-brachial index values were calculated for the ulcerated limb. The primary outcome measure was wound healing, defined as complete epithelization without any drainage confirmed for at least 10 days after closure was first documented at 24 weeks. Results: During the follow-up period 14 patients (66.66 %) healed and 7 patients did not heal (33.3%) by 24 weeks. The TcpO2 optimal cut-off point as determined by a balance of sensitivity and specificity of 28.5 mm Hg that yielded a sensitivity of 91% and a specificity of 100%, and area under the curve of 0.989 (P = .005; 95% confidence interval [CI], 0.945-1.000). Followed by the oxygen saturation of the hemoglobin optimal cut-off point as determined by a balance of sensitivity and specificity of 48.5 mm Hg that yielded a sensitivity of 93% and a specificity of 0.71%, and area under the curve of 0.932 (P = .013; 95% CI, 0.787-1.000). The logistic regression analyses showed that TcpO2 was the only variable associated with wound healing at 24 weeks (P < .001; 95% CI, 0.046-0.642). Conclusions: The HSI was shown to be effective in the prognosis of DFU healing compared with other noninvasive test; only TcpO2 values resulted in better diagnosis potential in wound healing.

    Complications associated with the approach to metatarsal head resection in diabetic foot osteomyelitis
    (Wiley-Blackwell, 2018-12-04) Tardaguila García, Aroa; Sanz Corbalán, Irene; Molines Barroso, Raúl Juan; Álvaro Afonso, Francisco Javier; García Álvarez, Yolanda; Lázaro Martínez, José Luis
    The aim of this study was to evaluate the recovery time and the development of complications in the dorsal and plantar approach to metatarsal head resections (MHR) in patients with diabetic foot ulcers complicated by osteomyelitis. A retrospective study was carried out involving 108 patients who underwent MHRs for the treatment of diabetic foot osteomyelitis. Two cohorts were defined: dorsal approach with incision closed with sutures and plantar approach with ulcer healed using conservative treatment. The main outcomes were the weeks until healing and complications related to the approaches. Fifty-three patients (49.1%) underwent a plantar approach and 55 (50.9%) a dorsal approach. Both approaches rendered similar healing times. However, the patients undergoing a dorsal approach developed more post-surgical complications than patients treated through a plantar approach. The dorsal approach intervention was performed on smaller and shallower ulcers; however, more complications developed at follow up using this approach than through a plantar approach for MHR complicated with osteomyelitis.

    (MDPI, 2022-07-14) López Moral, Mateo; Molines Barroso, Raúl J.; García Álvarez, Yolanda; Sanz Corbalán, Irene; Tardaguila García, Aroa; Lázaro Martínez, José Luis
    To assess long-term clinical outcomes of patients who underwent isolated versus several percutaneous flexor tenotomies for the treatment of toe deformities and previous diabetic foot ulcers; Methods: Twenty-three patients (mean age 66.26 ± 11.20, years) who underwent prophylactic percutaneous flexor tenotomies secondary to tip-toe ulcers participated in this 1-year prospective study. The study was stratified into two groups for analyses: (1) isolated tenotomies patients, and (2) several tenotomies patients (two or more tenotomies). Outcome measures were toe reulceration and recurrence, minor lesions, digital deformities, and peak plantar pressure (PPP—N/cm2) and pressure/time Integral (PTI—N/cm2/s) in the hallux and minor toes after a 1-year follow-up period; Results: Patients with isolated tenotomies (n = 11, 35.48%) showed a higher rate of reulceration (n = 8, 72.7%, p < 0.001) in the adjacent toes, additionally, we found more prevalence of hyperkeratosis (n = 11, 100%), minor lesions (n = 9, 81%), and claw toes (n = 11, 100%) (p < 0.001). In several tenotomies patients (n = 20, 64.52%), we found a higher rate of floating toes (n = 16, 80%) in comparison with isolated tenotomies patients (p < 0.001). PPP and PTI in the non-tenotomy toes were higher in the group of patients who underwent isolated tenotomies (p < 0.001); Conclusions: Patients who underwent several tenotomies had better clinical outcomes after a 1-year follow-up period compared to isolated tenotomies.

    Metatarsal Head Resections in Diabetic Foot Patients: A Systematic Review
    (MDPI, 2020) Sanz Corbalán, Irene; Tardaguila García, Aroa; García-Alamino, Josep M.; García Álvarez, Yolanda; Álvaro Afonso, Francisco Javier; Lázaro Martínez, José Luis
    A systematic review and proportional meta-analysis were carried out to investigate the complications that occur after surgical metatarsal head resection in diabetic foot patients. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist recommendations were applied, and the selected studies were evaluated using a Strengthening the Reporting of Observational studies in Epidemiology (STROBE) checklist. PubMed (Medline) and Embase (Elsevier) were searched in December 2019 to find clinical trials, cohort studies, or case series assessing the efficacy of the metatarsal head resection technique in diabetic foot patients. The systematic review covered 21 studies that satisfied the inclusion criteria and included 483 subjects. The outcomes evaluated were the time to heal, recurrence, reulceration, amputation, and other complications. The proportion of recurrence was 7.2% [confidence interval (CI) 4.0–10.4, p < 0.001], that of reulceration was 20.7% (CI 11.6–29.8, p < 0.001), and that of amputation was 7.6% (CI 3.4–11.8, p < 0.001). A heterogeneity test indicated I 2 = 72.6% (p < 0.001) for recurrences, I 2 = 94% (p < 0.001) for reulcerations, and I 2 = 79% (p < 0.001) for amputations. We conclude that metatarsal head resections in diabetic foot patients are correlated with significant complications, especially reulceration.

    Long-Term Complications after Surgical or Medical Treatment of Predominantly Forefoot Diabetic Foot Osteomyelitis: 1 Year Follow Up
    (MPDI, 2021-05-01) Tardaguila García, Aroa; García Álvarez, Yolanda; García Morales, Esther Alicia; López Moral, Mateo; Sanz Corbalán, Irene; Lázaro Martínez, José Luis
    Aim: To compare long-term complications according to the treatment received for management of diabetic foot osteomyelitis (surgical or medical) at 1 year follow up. Design and Participants: A prospective observational study was conducted involving 116 patients with diabetic foot osteomyelitis. The patients received surgical or medical treatment based on the principles described in the literature. To register the development of a complication, both groups of treatments were followed-up 1 year after the ulcer had healed. Results: Ninety-six (82.8%) patients received surgical treatment and 20 (17.2%) medical treatment. No differences were found in the time to healing between both groups of treatment, 15.7 ± 9.2 weeks in the surgical group versus 16.4 ± 12.1 weeks in the medical group; p = 0.103. During follow up, 85 (73.3%) patients developed complications without differences between both groups, 68 (70.8%) in the surgical group versus 17 (85%) in the medical group (p = 0.193). The most common complication in both groups was re-ulceration. We did not observe significant differences comparing complication-free time survival between both treatments (p = 0.665). Conclusion: The onset of complications after healing in patients who suffered from diabetic foot osteomyelitis was not associated with the treatment received. Surgical and medical approaches to the management of diabetic foot osteomyelitis produced similar results in long-term follow up.

    Predictive Radiographic Values for Foot Ulceration in Persons with Charcot Foot Divided by Lateral or Medial Midfoot Deformity
    (MPDI, 2022-01-18) López Moral, Mateo; Molines Barroso, Raúl J.; Sanz Corbalán, Irene; Tardaguila García, Aroa; García-Madrid Martín de Almagro, Marta; Lázaro Martínez, José Luis
    Background: To identify differences in radiographic outcomes in weight-bearing lateral X-ray to predict the probability of ulceration in patients with midfoot Charcot neuroarthropathy (CN) differentiated by lateral and medial column deformities. Methods: Thirty-five patients who suffered from CN midfoot deformity participated in this 1 year prospective study in a specialized diabetic foot unit. Lateral talar-first metatarsal angle, calcaneal pitch, and cuboid height were performed by digital radiographs in the weight-bearing lateral view. Patients were followed up for 1 year or until an ulcer ulceration event occurred in the midfoot region. Results: ROC analyses showed that all patients with medial pattern deformity that developed a midfoot ulcer had a lateral talar-first metatarsal angle greater (negative) than −27.5 degrees (°). All patients with lateral pattern deformity that developed a midfoot ulcer had a calcaneal pitch greater (more negative) than −5° and a cuboid height greater (more negative) than −1.5°. Conclusions: Lateral talar-first metatarsal angle was the greatest predictor of midfoot ulceration, with greater than −27.5° measurement correlating with ulceration occurrence in patients with medial deformity. Calcaneal pitch and cuboid height were the greatest predictors of midfoot ulceration with greater than −5 and −1.5°, respectively in patients with CN lateral deformity.
