RESUMO
AIM: The aim of this study was to investigate the health-related quality of life of Spanish outpatients with diabetic foot ulcer using the Diabetic Foot Scale-Short Form (DFS-SF). MATERIALS AND METHODS: This cross-sectional observational study included 141 outpatients with diabetic foot ulcers (DFU). The DFS-SF was applied in personal interviews conducted by a trained investigator to assess health-related quality of life (HRQoL). RESULTS: The domain related to "worried about ulcers" had the lowest in score [50 (27.5-65.0)], and the highest score was in the physical health domain [76 (60.0-88.0)]. There was a statistically significant difference in the ulcer type and the physical health subscale, finding the lowest values in the physical health subscale in patients with ischaemic diabetic foot ulcers [58 (39.0-70.0), p = 0.007]. In the multivariable analysis the domains Leisure (OR 0.98, 95% CI 0.97-0.99) and worried about ulcers/feet (OR 0.98, 95% CI 0.96-0.99) were identified as significant independent domains in patients with the experience of a previous minor amputation. A significant negative correlation was observed between the SINBAD DFU score and leisure (r = -0.181, p = 0.032), physical health (r = -0.202, p = 0.016), dependence/daily life (r = -0.232, p = 0.006), and the "bothered by ulcer care" (r = -0.239, p = 0.004) domains of the DFS-SF. The ulcer duration had a significant negative correlation with all the domains of DFS-SF. CONCLUSION: The DFS-SF survey is a specific instrument that could be implemented in diabetic foot units as part of the management of patients with DFU to evaluate HRQoL. The domain of "worried about ulcers" had the lowest score in our population suggesting that clinicians should try to work on the emotional state of patients with DFU. The mean duration of DFU was the most influential factor related to worse scores followed by previous amputations. The SINBAD score had significant negative correlations suggesting that HRQoL may be related to the severity of DFU in this study population.

OBJECTIVE: To analyze and compare the development of short- and long-term complications in patients with diabetic foot after digital arthroplasty or arthrodesis. METHODS: The authors reviewed patient records from January 2017 to March 2020. Patients were treated by digital arthroplasty or arthrodesis to correct toe deformity (elective or prophylactic surgery), achieve ulcer healing in toes (curative surgery), or manage toe infection (emergent surgery). During 1-year follow-up, researchers registered short- and long-term complications. Researchers analyzed the association between the type of surgery and the development of short- and long-term complications. RESULTS: Forty-four patients (83.0%) received arthroplasty, and nine (17.0%) received arthrodesis. The mean time to heal from ulcers was 5.2 ± 5.2 weeks. A significant association was observed between arthrodesis and the development of long-term complications (P = .044; odds ratio, 5.1; 95% confidence interval, 0.9-27.2). No differences were observed between type of surgery and short- or long-term complications. Moreover, both short- and long-term complications were related to longer time to heal (respectively, 7.6 ± 6.0 vs 2.1 ± 0.5 weeks, P < .001; and 6.3 ± 6.2 vs 4.2 ± 4.0 weeks, P = .039). CONCLUSIONS: Digital arthroplasty or arthrodesis are good options for managing patients with diabetic foot who require digital deformity correction to achieve digital ulcer healing or management of diabetic foot infection in phalanges.

There are a wide variety of treatments for plantar warts, but none has been shown to be effective in all patients. We aimed to perform a systematic review of the efficacy of different topical treatments on plantar warts. Systematic electronic searches (Pubmed, Cochrane Library, Embase, and Web of Science) were conducted in April 2020. Meta-analyses, systematic reviews, and retrospective or prospective clinical trials of the effects of topical and nonsurgical treatments of plantar warts were included. Two authors performed the study selection and data extraction. Any discrepancies between the two reviewers were discussed with a third reviewer. Forty-four studies were included. The average cure rates of the most frequent treatments were variable across the studies: cryotherapy (45.61%), salicylic acid (13.6%), cantharidin-podophyllin-salicylic acid formulation (97.82%), laser (79.36%), topical antivirals (72.45%), intralesional bleomycin (83.37%), and intralesional immunotherapy (68.14%). Twenty-two studies (50%) had a level of evidence 1b and grade of recommendation A, five studies (11.4%) had a level of evidence 2b and grade of recommendation B, two studies (4.5%) had a level of evidence 3b and grade of recommendation B, and 15 studies (34,1%) with a level of evidence 4 and grade of recommendation C. First-choice treatments for common warts, such as cryotherapy and salicylic acid, have low-cure rates for plantar warts. Other treatments, such as CPA formulation, immunotherapy, and intralesional bleomycin, which have compassionate use, have higher cure rates. This review should stimulate future high-quality research to evaluate these specialized treatments.

OBJECTIVE: To compare the diagnostic accuracy of bone culture (microbiology) and biopsy (histology) in patients with acute or chronic diabetic foot osteomyelitis (DFO). METHODS: This cross-sectional study involved patients for whom providers had a clinical suspicion of DFO. Two bone samples were taken: one for microbiologic testing and another for histologic testing. The sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio were calculated for bone culture results in relation to the probability of DFO diagnosis. RESULTS: Fifty-two patients were included; 69% had positive bone culture results, and 90.4% had positive histology results (P = .013), and of those 90.4%, 25.5% had acute and 74.5% had chronic DFO. The sensitivity of the microbiologic bone culture result was 0.70, the specificity was 0.40, the positive predictive value was 0.92, and the negative predictive value was 0.13. CONCLUSIONS: Histology provides more accurate diagnosis of DFO than microbiology, especially for patients with chronic DFO. These patients could be underdiagnosed because of false-negative results provided by bone culture. Providers should perform both tests to confirm the presence of DFO.

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.

OBJECTIVE: To describe the outcomes of a new product based on negatively charged polystyrene microspheres (NCM) technology, in non-responding diabetic foot ulcers (DFU). METHODS: A clinical case series of patients with a hard-to-heal DFU treated with NCM were recruited between March and June 2017 in a specialised diabetic foot unit. DFUs were treated daily with NCM over four weeks, although the health professional could decide to continue NCM treatment in some patients. Cases were followed up for 12 weeks. Wollina score (granulation, colour and consistency tissue), wound area (cm2), percentage reduction and wound closure (%) were measured. RESULTS: A total of 22 ulcers (19 patients) were included, of which three patients (five ulcers) were withdrawn due to adverse events: four infections and one necrosis. None were associated with the product. NCM treatment was completed in 17 ulcers (16 patients). The mean patient age was 61.53±9.57 years. At baseline, mean duration time of the DFU was 7.88±8.65 weeks, the median area was 5.35cm2, the interquartile range (IQR) was 1.45 to 4.65cm2 and positive probe-to-bone test (PTB+) was recorded at 29.4%. After four weeks of treatment, an increase in Wollina score (3.65±2.12 to 5.69±1.18; p=0.000), a 62.2% reduction of the ulcer area (5.35 cm2; IQR: 1.45 to 4.65cm2) to 3.33cm2 (IQR: 0.25 to 1.70cm2; p<0.001) and complete healing in 17.6% of ulcers was observed. The mean time of NCM treatment was 6.2±1.2 weeks. At 12 weeks, 100% achieved complete healing, including those ulcers with PTB+. CONCLUSION: After NCM use, a reactivation of the healing process in non-responding wounds was observed, having a significant improvement in Wollina score as well as reduction of the wounds. Complete healing was achieved in all ulcers at 12 weeks, including PTB+.

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.

The aim of this study is to evaluate the prevalence of digital deformities in patients with diabetes mellitus according to the McGlamry classification and relate the types of digital deformities with the history of digital ulcer. A cross-sectional study was performed in the diabetic foot unit between September 2016 and September 2017. All consecutive patients were classified by digital deformities according to the McGlamry classification (flexor stabilization, flexor substitution, and extensor substitution) using slow-motion videos. In all patients, the Foot Posture Index 6 was performed and previous toe ulceration, toe calluses, and nail dystrophy were evaluated. A total of 142 feet were evaluated, in which 29 (20.27%) feet did not show dynamic deformities, 65 (57.5%) were classified as flexor stabilization, 9 (8%) as flexor substitution, and 39 (34.5%) as extensor substitution. In total, 23% the feet with previous ulcer were classified as extensor substitution. A previous toe ulcer on the tip (pâ¯=â¯.033; confidence interval [CI] 1.06 to 4.99; odds ratio [OR] 2.3), pronated foot according to the Foot Posture Index 6 (pâ¯=â¯.048; 95% CI 0.9 to 8.9; OR 2.9), and callus on the tip (pâ¯=â¯.002; 95% CI 1.47 to 6.41; OR 3.07) were associated with flexor stabilization deformities. Flexor stabilization, associated with the pronated foot, was the most prevalent dynamic deformity. Extensor substitution was present in approximately 40% of the patients and in 20% of the patients with previous ulcer, in whom flexor tenotomy could aggravate the digital deformity. An evaluation of dynamic deformities during gait should be included as a presurgical assessment to achieve successful surgical results.

OBJECTIVE: To evaluate the clinical and microbiological effects of sequential wound debridement in a case series of neuroischaemic diabetic foot ulcers (DFUs) using an ultrasound-assisted wound debridement (UAW) device. METHOD: A prospective, single-centre study, involving a case series of 24 neuroischaemic DFUs, was conducted to evaluate sequential wound debridement with UAW during a six-week treatment period. Soft tissue punch biopsies were taken every second week of treatment, both before and after wound debridement sessions. Qualitative and quantitative microbiological analysis was performed and wounds were assessed at patient admission, and before and after each debridement procedure. RESULTS: Wound tissue quality scores improved significantly from a mean score of 2.1±1.3 points at patient inclusion, to 5.3±1.7 points (p=0.001). Mean wound sizes were 4.45cm2 (range: 2-12.25cm2) at week zero, and 2.75cm2 (range: 1.67-10.70cm2) at week six (p=0.04). The mean number of bacterial species per culture determined at week zero and at week six was 2.53±1.55 and 1.90±1.16, respectively (p=0.023). Wound debridement resulted in significant decreases in bacterial counts (1.17, 1.31 and 0.77 log units in colony forming units (CFU) for week zero, three and six, respectively). The average bacterial load in tissue samples before and after wound debridement after the six-week treatment was Log 5.55±0.91CFU/g and Log 4.59±0.89CFU/g, respectively (p<0.001). CONCLUSIONS: The study results showed a significant bacterial load reduction in DFU tissue samples as a result of UAW debridement, independent of bacterial species, some of which exhibited antibiotic-resistance. Significant bacterial load reduction was correlated with improved wound conditions and significant reductions of wound size.

Self-stigma specifically in people with schizophrenia has been little studied. The aims of the present study were to validate a new instrument for the assessment of self-stigma (SSQ) and to assess the relationship between self-stigma and social functioning in people with schizophrenia. A sample of 76 people with schizophrenia was assessed at two moments in time with the SSQ, the PDD (stigma), two scales of social functioning (LSP, SFS), and a scale of general functioning (GAF). The results indicated that SSQ presented good psychometric properties, with Cronbach's alpha ranging between 0.75 and 0.901. The stability of the instrument was between 0.836 and 0.402. Three factors were found in the factor analysis (social discrimination, perceived capabilities, concealment of the disease), explaining 62.66% of the total variance. A relationship was found between self-stigma and social functioning in people with schizophrenia, especially in relation to social contact. In conclusion, the SSQ seems to be a valid and reliable questionnaire for the assessment of self-stigma in people with schizophrenia, and interventions should be designed to cope with self-stigma in order to improve the social functioning of people who suffer schizophrenia.

The objective of this study was to identify bone fractures and joint dislocations that have greater association with the severity of arch collapse in patients with Charcot foot involving the midfoot.A retrospective study in 28 (N = 29 feet) patients who had Charcot foot deformity of the midfoot. The study included stage III of Eichenholtz classification, and Schon classification types I to III. Talar-first metatarsal and calcaneal pitch angles and cuboid height were used to evaluate the severity of the midfoot deformity in a weightbearing lateral radiograph. Two investigators evaluated the bone fracture and joint dislocation involved in weightbearing antero-posterior and lateral radiographs.There were 13 (46%) feet that showed pattern 1, 9 (31%) feet with pattern 2, and 7 (25%) feet with pattern 3 according to the Schon classification. One foot had a combination of patterns 1 and 2. Midfoot ulceration occurred in 64% (n = 19) of feet. In the multivariate analysis, plantarflexion of talar-first metatarsal angle was predicted by navicular-medial cuneiform dislocation (p = .007 [-20.620-3.683]), an increase of the negative calcaneal pitch angle by fragmentation of the cuboid (p = .003 [-15.568-3.626]), and increment of the negative cuboid height by navicular-medial cuneiform and medial cuneiform-first metatarsal dislocations (p = .040 [-12.779-0.317], p = .002 [-13.437-3.267], respectively).Bone fractures and dislocations in the sagittal plane seem to contribute to midfoot collapse, but navicular-medial cuneiform dislocation/non-union and cuboid fragmentation predict severe rocker-bottom deformity in cases of Charcot foot.
RESUMO
BACKGROUND: Few studies have addressed the relationship of human papillomavirus (HPV) biotypes to patient characteristics and the clinical signs, course, and response to the treatment of plantar warts. OBJECTIVE: Analyze the HPV types associated with plantar warts and their relationship with warts characteristics, patient characteristics and response to treatment. METHODS: A total of 372 patients sampled for hyperkeratosis of a plantar wart were included. Multiplex polymerase chain reaction (PCR) was performed to detect the HPV biotype. RESULTS: The prevalence of HPV was 81.2%, and HPV1 was the most prevalent biotype (36.1%). HPV1 was the most prevalent biotype in patients < 70 years old (90.9% in < 10 years), and biotypes 2, 19 and 27 were the most prevalent in patients > 70 years old (p = 0.012). HPV1 was the most frequent in patients with one (39,9%) or two (47.1%) warts and HPV5 (33.3%) in patients with three warts (p < 0.001). Cure, spontaneous resolution, and recurrence were higher in HPV1 (p < 0.001). HPV14 warts healed the fastest (2 months quartile 1-3 (2.0-2.0)), and HPV5 (10.977 (6.0-20.0)) and HPV27 (7.5 (3.0-10.0)) warts (p = 0.033) took the longest to heal. CONCLUSIONS: HPV biotype is associated with age and the number of warts and appears to influence the natural history of warts and their response to treatment.

BACKGROUND/OBJECTIVES: To analyze the best noninvasive tests prognosis marker in patients with diabetic foot ulcer (DFU) who underwent endovascular revascularization based on clinical outcomes, such as healing rate, time to heal, and free amputation survival after at least a six-month follow-up. METHODS: A multicentric prospective observational study was performed with 28 participants with ischemic or neuroischemic DFU who came to the participant centers and underwent endovascular revascularization between January 2022 and March 2023. Toe systolic pressure (TP), ankle systolic pressure (AP), the ankle brachial pressure index (ABPI), the toe brachial pressure index (TBPI), transcutaneous pressure of oxygen (TcPO2), and skin perfusion pressure (SPP) were evaluated using PeriFlux 6000 System, Perimed, Sweden, before (Visit 0) and four weeks after revascularization (Visit 1). The primary clinical outcome was an evaluation of the clinical evolution of noninvasive tests comparing Visit 0 and Visit 1, estimating the sensitivity for predicting wound healing of noninvasive tests at six months following initial recruitment. RESULTS: After six months, 71.43% (n = 20) of DFU healed, four patients (14.3%) received major amputations, and one (3.5%) died. The two tests that best predicted wound healing after revascularization according to the ROC curve were TcPO2 and TP with sensitivities of 0.89 and 0.70 for the cut-off points of 24 mmHg and 46 mmHg, respectively. CONCLUSIONS: TcPO2 and TP were the two tests that best predicted wound healing in patients who underwent endovascular revascularization. Clinicians should consider the importance of the evaluation of microcirculation in the healing prognosis of patients with diabetic foot ulcers.
RESUMO
Microbiological cultures of per-wound bone biopsies have shown a lack of correlation and a high rate of false-negative results when compared with bone biopsy cultures in diabetic foot osteomyelitis. The selection of samples from the area of active osteomyelitis, which contains a complete census of the microorganisms responsible for the infection, is essential to properly guide antimicrobial treatment. We aimed to comparatively evaluate the quantitative and qualitative cultures taken from different areas, in metatarsal heads resected for osteomyelitis. For this purpose, we consecutively selected 13 metatarsal heads from 12 outpatients with plantar ulcers admitted to our diabetic foot unit. Metatarsal heads were divided transversally into 3 portions: plantar (A), central (B), and dorsal (C), and the 39 resulting samples were cultured. Qualitative and quantitative microbiological analysis was performed, and the isolated species and bacterial load, total and species specific, were compared between the 3 metatarsal bone segments. The primary outcome of the study was the bacterial diversity detected in the different bone sections. Cultures were positive in 12 of the 13 included metatarsal heads (92%). A total of 34 organisms were isolated from all specimens. Ten of the 12 cultures (83%) were polymicrobial. Ten of the 13 metatarsal heads (77%) had identical microbiological results in each of the 3 bone sections. The largest number of microorganisms was found in the central section. The overall concordance between sections was 91%. The predominant microorganisms were coagulase-negative staphylococci (41%). Statistical differences were not found in the bioburden between sections (range 3.25-3.41 log10 colony-forming unit/g for all sections; P = .511). The results of our study suggest that microorganisms exhibit a high tendency to spread along the metatarsal bone and that the degree of progression along the bone is species dependent. The central portions of metatarsal bones tend to accumulate a higher diversity of species. Thus, we recommend this area of bone for targeted biopsy in patients with suspected osteomyelitis.

The aim of our study was to analyze the influence of radiographic arterial calcification (RAC) on clinical outcomes and wound healing in patients with diabetic foot ulcers complicated by osteomyelitis treated by surgery. We analyzed retrospectively the clinical records of 102 patients with diabetic foot osteomyelitis who underwent surgery at a specialized diabetic foot unit between January 2014 and December 2016. The clinical data of evolution until its complete epithelialization and a follow-up 1 year were reviewed, and after reviewing the radiological images, patients were classified into 2 groups: those with RAC and those without RAC. We analyzed several clinical features in both groups. The presence of RAC was associated with a greater time of healing (10.68 ± 7.24 vs 8.11 ± 4.50 weeks; P = .029) and shorter time to recurrence and reulceration (13.30 ± 9.25 vs 18.81 ± 11.63 weeks; P = .036). However, this association was not found for patients with mild and moderate peripheral artery disease (PAD), whose time of healing was 8.97 ± 4.51 weeks compared to 9.16 ± 6.39 weeks for patients without PAD; P = .864. The time of healing of diabetic foot ulcers complicated by osteomyelitis treated by surgery can be negatively affected by the presence of RAC even more than by the presence of mild and moderate ischemia. The presence of RAC may offer clinical guidance at the level of primary care though this would need thorough validation in future studies.

Therapeutic footwear (TF) has been demonstrated to decrease the rate of recurrence in patients in remission. TF adherence determines the real effect of such treatment and, therefore, an appropriate evaluation of TF adherence is critical to decrease recurrence. The aim of this systematic review was to determine the usability of different methods of assessing adherence to TF in patients with diabetic foot ulcers under remission. The search strategy retrieved 506 articles. Title and abstract review excluded 472, while the full-text review excluded an additional 18 articles because the included data did not meet the selection criteria. Finally, we included 16 articles in this systematic review. Six (37.5%) of the 16 studies combined objective (OM) and subjective methods (SM). Only five (31.25%) evaluated OM and six (37.5%) studies only evaluated SM. Objective methods (temperature sensor, activity monitor) and subjective methods (survey, questionnaire) have successfully been used in the literature to evaluate TF adherence. Objective methods provided accurate data, whereas subjective methods led to response bias or missing data. Methods of evaluation showed that patients use the TF more frequently outdoors and on weekdays than indoors or on the weekend. In conclusion, objective methods are the most usable way to measure adherence to TF.
RESUMO
A systematic review and meta-analysis was conducted to assess the diagnostic accuracy of the combination of plain X-ray and probe-to-bone (PTB) test for diagnosing diabetic foot osteomyelitis (DFO). This systematic review has been registered in PROSPERO (a prospective international register of systematic reviews; identification code CRD42023436757). A literature search was conducted for each test separately along with a third search for their combination. A total of 18 articles were found and divided into three groups for separate analysis and comparison. All selected studies were evaluated using STROBE guidelines to assess the quality of reporting for observational studies. Meta-DiSc software was used to analyze the collected data. Concerning the diagnostic accuracy variables for each case, the pooled sensitivity (SEN) was higher for the combination of PTB and plain X-ray [0.94 (PTB + X-ray) vs. 0.91 (PTB) vs. 0.76 (X-ray)], as was the diagnostic odds ratio (DOR) (82.212 (PTB + X-ray) vs. 57.444 (PTB) vs. 4.897 (X-ray)). The specificity (SPE) and positive likelihood ratio (LR+) were equally satisfactory for the diagnostic combination but somewhat lower than for PTB alone (SPE: 0.83 (PTB + X-ray) vs. 0.86 (PTB) vs. 0.76 (X-ray); LR+: 5.684 (PTB + X-ray) vs. 6.344 (PTB) vs. 1.969 (X-ray)). The combination of PTB and plain X-ray showed high diagnostic accuracy comparable to that of MRI and histopathology diagnosis (the gold standard), so it could be considered useful for the diagnosis of DFO. In addition, this diagnostic combination is accessible and inexpensive but requires training and experience to correctly interpret the results. Therefore, recommendations for this technique should be included in the context of specialized units with a high prevalence of DFO.
RESUMO
AIMS: To assesses the relationship between the wear and tear of therapeutic footwear (TF) and the risk of recurrence in diabetes remission patients. METHODS: Remission patients (N = 115) participated in this 5-year prospective study in a specialized Diabetic Foot Unit between October 2016 and January 2022. Patients' TF was assessed in a three-month interval from Day 0 until ulcer recurrence was found. Primary outcome measure was based on the recurrent event in the forefoot. RESULTS: A total of 82 patients (71.3%) renewed their TF, and 33 patients (28.7%) did not renew their TF during the follow-up period. Patients who failed to renew their TF group experienced more recurrent events (22 vs 14, p <.001, CI [0.04-0.259]) and minor amputations (11 vs 8, p =.002, CI [0.07-0.6]). Both groups showed different recurrence-free survival median times of 205.5 [Interquartile range (IQR) - 188-222] weeks and 89.9 [IQR - 53-126] weeks. Patients who did not renew their TF increased their risk of suffering from a recurrent event in the Cox regression model (p <.001, CI [0.03-0.38], Hazzard Ratio 0.147). CONCLUSIONS: Patients who renewed their TF because of wear and tear experienced lower recurrences and minor amputations.

A systematic review and meta-analysis were carried out to investigate the effect of ultrasound-assisted wound (UAW) debridement in patients with diabetic foot ulcers (DFUs). All selected studies were evaluated using the Cochrane risk of bias tool to assess the risk of bias for randomized controlled trials. PubMed and Web of Science were searched in October 2021 to find randomized clinical trials (RCT) assessing the effect of UAW debridement on DFUs. RevMan v5.4. was used to analyze the data with the Mantel-Haenszel method for dichotomous outcomes. A total of 8 RCT met our inclusion criteria, with 263 participants. Concerning the healing rate comparing UAW versus the control group, a meta-analysis estimated the pooled OR at 2.22 (95% CI 0.96-5.11, p = 0.06), favoring UAW debridement, with low heterogeneity (x2 = 7.47, df = 5, p = 0.19, I2 = 33%). Time to healing was similar in both groups: UAW group (14.25 ± 10.10 weeks) versus the control group (13.38 ± 1.99 weeks, p = 0.87). Wound area reduction was greater in the UAW debridement group (74.58% ± 19.21%) than in the control group (56.86% ± 25.09%), although no significant differences were observed between them (p = 0.24). UAW debridement showed higher healing rates, a greater percentage of wound area reduction, and similar healing times when compared with placebo (sham device) and standard of care in patients with DFUs, although no statistically significant differences were observed between groups.
RESUMO
Few studies have addressed the interaction of specific pathogens with clinical outcomes in patients with diabetic foot infection (DFI). Our study aim was to compare the clinical outcomes among patients with DFI caused by methicillin-resistant Staphylococcus aureus (MRSA) with cases caused by methicillin-sensitive Staphylococcus aureus (MSSA). We gathered the data of 75 consecutive patients admitted at specialized outpatients diabetic with mild or moderate DFI in which S. aureus was isolated from bone or soft tissue specimens in pure or as a part of the polymicrobial culture. Patients were divided into two groups: those with MRSA infection and those with MSSA infection. Patients with MRSA diabetic foot infections were significantly associated with male gender (86% vs. 64%, P = .029), higher SINBAD Classification Score (3.6 ± 0.99 points vs. 2.8 ± 1.06 points, P = .001), longer mean wound evolution [17.8 (3;29.5) weeks versus 9.1 (1;12) weeks, P = .008], bone involvement [18 (50%) versus 9 (23.1%), P = .015] and longer mean healing time [18.2(8;28) weeks versus 9.1 (1;12) weeks, P = .008]. In addition, male gender (OR 8.81, 95% CI 2.00-38.84) and SINBAD Classification Score (OR 2.70, 1.46-5.00) were identified as independent risk factors for MRSA DFI. Significant differences in the number of surgical procedures to resolve infection [15 (41.7%) versus 13 (33.3%), P = .456] or in the mean healing time after surgical treatment [10.5 weeks (6.7;16.5) versus 6.1 weeks (3;8.7), P = .068] were not observed among groups, suggesting that when treatment is based on early and surgical debridement, MRSA infections are not associated with worse prognosis. In conclusion MRSA DFI has importance in clinical outcomes such as time to healing. We propose that recent lines of research regarding the genetic virulence of strains of S. aureus could provide new insights into our results.
