Randomized Double-blind Cost-effectiveness Comparison of Two 10% Urea Creams in Patients with Diabetic Foot Syndrome.

OBJECTIVE: To evaluate the cost-effectiveness of two 10% urea creams in patients with diabetic foot syndrome. METHODS: This was a prospective, longitudinal, single-center, randomized, double-blind, prospective clinical trial that evaluated the skin quality of 20 feet belonging to 10 patients with diabetic foot syndrome after the application of two 10% urea creams purchased from pharmacies and supermarkets. RESULTS: At follow-up, 19 (95%) of the participants' feet showed improved skin quality, irrespective of the cream applied. On visual inspection, participants had a decreased presence of xerosis, hyperkeratosis, and preulcerative signs such as subkeratotic bruising and areas of redness on the dorsum of the toes. At the 3-month follow-up, nine (90%) of the participants stated that they had continued to apply the cream as a method of self-management to prevent complications. CONCLUSIONS: Creams containing 10% urea purchased in supermarkets improve foot skin quality in patients with diabetic foot syndrome, regardless of their cost. Based on these findings, the authors recommend creams containing 10% urea as a self-management tool for patients with diabetic foot syndrome.

Diagnostic Performance of Atherogenic Index of Plasma for Predicting Diabetic Foot Osteomyelitis with Peripheral Artery Disease.

Background: This study aims to assess the atherogenic index of plasma (AIP) diagnostic value in detecting diabetic foot osteomyelitis (DFO) among patients with diabetic foot ulcers (DFUs). Methods: A prospective cohort study was conducted on 80 patients with DFUs and suspected DFO between January 2022 and December 2023. The primary outcome measures included the diagnosis of DFO, determined by positive microbiological analysis results from bone samples and its correlation with the AIP. Receiver operating characteristic (ROC) curves were utilized to select the optimal diagnostic cut-off points for AIP and post hoc analysis was performed to evaluate the difference in the AIP for diagnosing DFO in patients with and without peripheral arterial disease (PAD). Results: The diagnostic potential for DFO in PAD patients of AIP-1 (Log TC/HDL) showed an AUC of 0.914 (p < 0.001 [0.832-0.996]), leading to a sensitivity of 83% and a specificity of 85%. By contrast, AIP-2 (Log TG/HDL) demonstrated a slightly lower AUC of 0.841 (p < 0.001 [0.716-0.967]), leading to a sensitivity of 76% and a specificity of 74%. Conclusions: The AIP tool, with its ideal blend of sensitivity and specificity, aids in predicting DFO effectively. Therefore, clinicians should consider using AIP for patients suffering from PAD and associated DFO.

M.O.I.S.T. Concept for the Local Therapy of Chronic Wounds: An International Update.

Chronic wounds remain a significant clinical challenge both for those affected and for healthcare systems. The treatment is often comprised and complex. All patients should receive wound care that is integrated into a holistic approach involving local management that addresses the underlying etiology and provides for gold standard therapy to support healing, avoid complications and be more cost effective. There have been significant advances in medicine over the last few decades. The development of new technologies and therapeutics for the local treatment of wounds is also constantly increasing. To help standardize clinical practice with regard to the multitude of wound products, the M.O.I.S.T. concept was developed by a multidisciplinary expert group. The M stands for moisture balance, O for oxygen balance, I for infection control, S for supporting strategies, and T for tissue management. Since the M.O.I.S.T. concept, which originated in the German-speaking countries, is now intended to provide healthcare professionals with an adapted instrument to be used in clinical practice, and a recent update to the concept has been undertaken by a group of interdisciplinary experts to align it with international standards. The M.O.I.S.T. concept can now be used internationally both as an educational tool and for the practical implementation of modern local treatment concepts for patients with chronic wounds and can also be used in routine clinical practice.

Does HPV biotype influence the characteristics and evolution of plantar warts?

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.

Fluid handling by foam wound dressings: From engineering theory to advanced laboratory performance evaluations.

This article describes the contemporary bioengineering theory and practice of evaluating the fluid handling performance of foam-based dressings, with focus on the important and clinically relevant engineering structure-function relationships and on advanced laboratory testing methods for pre-clinical quantitative assessments of this common type of wound dressings. The effects of key wound dressing material-related and treatment-related physical factors on the absorbency and overall fluid handling of foam-based dressings are thoroughly and quantitively analysed. Discussions include exudate viscosity and temperature, action of mechanical forces and the dressing microstructure and associated interactions. Based on this comprehensive review, we propose a newly developed testing method, experimental metrics and clinical benchmarks that are clinically relevant and can set the standard for robust fluid handling performance evaluations. The purpose of this evaluative framework is to translate the physical characteristics and performance determinants of a foam dressing into achievable best clinical outcomes. These guiding principles are key to distinguishing desirable properties of a dressing that contribute to optimal performance in clinical settings.

Evaluation of usability, adherence, and clinical efficacy of therapeutic footwear in persons with diabetes at moderate to high risk of diabetic foot ulcers: A multicenter prospective study.

OBJECTIVE: To evaluate therapeutic footwear expectations and usability of individuals with diabetes and foot complications. DESIGN: A prospective multicenter study was conducted on participants with a high risk of developing a diabetic foot ulcer. SETTING: Participants were enrolled in 11 different specialized diabetic foot units in Spain between March 2022 and June 2023. SUBJECTS: Patients with diabetes at moderate to high risk of foot ulceration receiving first therapeutic footwear prescription. INTERVENTIONS: All the patients included in the research were prescribed with their first pair of therapeutic footwear. MAIN MEASURES: Primary outcome measures were MOS-pre and MOS-post questionnaires evaluating use and usability of prescribed therapeutic footwear. Secondary outcome measures aimed to evaluate footwear clinical efficacy as ulceration rate and self-reported perceived walking distance per day. RESULTS: The use of therapeutic footwear exceeded the patient's pre-provision prediction of their anticipated use in 94% of people (n = 126). Based on the visual analogic satisfaction scale, the median satisfaction of daily wearing their therapeutic footwear was 7 points, Interquartile Range (IQR) [5-8.25]. During the follow-up period, 39 participants (29.1%) experienced diabetic foot ulcer. Perceived walking distance participants reported an improvement in their perceived walking ability during various daily life activities. CONCLUSIONS: Diabetes patients at moderate to high risk of diabetic foot ulcer improved their perception of walking ability after therapeutic footwear prescription. Adherence to the therapeutic footwear prescription resulted in less ulcerations.

Disease Knowledge and Behavior Regarding Diabetic Foot Among Persons at Different Risks of Foot Ulceration According to the International Working Group Guidelines.

BACKGROUND: This article aims to analyze levels of knowledge and behavior about diabetic foot care and prevention in persons with diabetes according to International Working Group (IWGDF) risk stratification system. METHODS: A descriptive study in 83 persons with diabetes at different level of risk for foot ulceration (IWGDF risk 0-3). A previously validated questionnaire, the PIN Questionnaire, was used to analyze their levels of understanding of foot complications. Participants were responded on a 5-point Likert scale. RESULTS: IWGDF-3 risk patients knew that good circulation and absence of polyneuropathy in their feet were related to healthy feet relative to the other groups (19.6 ± 2.7, p<.001 and 14.2 ± 0.7, p<.001 respectively). Additionally, they knew that a foot ulcer (DFU) on their feet will not be painful relative to other groups (6.6 ± 2.8, p<.001). High-risk patients knew which physical causes could affect the development of a DFU (18 ± 1.4, p<.001) and that foot self-care and medical control could prevent DFU appearance (23.4 ± 2.15, p<.001 and 13.9 ± 0.9, p<.001 respectively). CONCLUSION: IWGDF-3 patients knew the natural progression of diabetes foot complications and how to prevent them. Clinicians should focus their efforts and educate diabetes at lower risk of foot ulcer.

Inter-observer reliability of the Onychomycosis Severity Index depending on clinical experience: A review of 50 cases.

BACKGROUND: Onychomycosis (ONM) is the most prevalent nail unit pathology, and its severity and monitoring are often based on the visual judgement of clinicians. OBJECTIVE: The objective of this study is to assess the reliability of the Onychomycosis Severity Index (OSI) classification when utilized by three clinicians with varying levels of clinical experience: an experienced podiatrist (with 5 years of experience), a moderately experienced podiatrist (with 2 years of experience) and an inexperienced podiatrist (a recent graduate familiar with the OSI classification but lacking clinical experience). Additionally, we compared the severity assessments made through visual inspection with those determined using the OSI by different clinicians. METHODS: We evaluated reliability using the intraclass correlation index (ICC), analysing 50 images of ONM. RESULTS: The OSI demonstrated a very high level of reliability (ICC: 0.889) across clinicians, irrespective of their experience levels. Conversely, a statistically significant increase in severity was observed when comparing visual assessments with the OSI (p < .001) for ONM severity evaluation. CONCLUSION: The OSI proves to be a reproducible classification system, regardless of the clinical experience of the practitioner employing it.

Health-related quality of life among Spanish patients with diabetic foot ulcer according to Diabetic Foot Ulcer Scale - Short Form.

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.

Diagnostic Performance of Ultrasonography for Diabetic Foot Osteomyelitis.

Objective: This study aims to analyze the potential diagnostic capability of ultrasonography (US) in detecting diabetic foot osteomyelitis (DFO) in patients with diabetic foot ulcers (DFUs). Approach: A 1-year prospective study was conducted on 47 consecutive patients with active DFUs and suspicion of DFO at a specialized diabetic foot unit. The following ultrasonographic features were evaluated at baseline: (1) periosteal reaction; (2) periosteal elevation; (3) cortical disruption; (4) sequestrum; and (5) positive power Doppler. The primary outcome measure aimed to establish the effectiveness of ultrasonographic features compared with aseptic bone culture for diagnosing DFO. Receiver operating characteristic (ROC) curves were utilized to evaluate the diagnostic performance of ultrasonographic features. Sample size could not be determined as it is the first study to assess ultrasonographic features for the diagnosis of DFO. The research adhered to the guidelines for diagnostic accuracy studies (Standards for Reporting of Diagnostic Accuracy Studies [STARD] 2015). Results: All patients (n = 24) diagnosed with DFO exhibited positive power Doppler, resulting in a sensitivity (S) and specificity (SP) of 1 and an area under the curve (AUC) of 1 (p < 0.001 [1-1]). Cortical disruption was present in 23 patients (95.8%) with DFO, yielding an S of 0.93, SP of 1, and AUC of 0.96 (p < 0.001 [0.88-1]). Innovation: It validates the diagnostic value of US for DFO as it is the first and largest study of its kind to establish a clear reference standard to guide clinician decision-making. Conclusion: This study demonstrates the effectiveness of cortical disruption and positive power Doppler in assessing DFO through US.

Hard-to-Heal Wound Healing: Superiority of Hydrogel EHO-85 (Containing Olea europaea Leaf Extract) vs. a Standard Hydrogel. A Randomized Controlled Trial.

Chronic wounds, especially those that are hard-to-heal, constitute a serious public-health problem. Although progress has been made in the development of wound dressings for healing, there is little high-quality evidence of their efficacy, with no evidence of superiority in the use of one hydrogel over another. To evaluate the superiority of a hydrogel (EHO-85), containing Olea europaea leaf extract (OELE), over a standard hydrogel (SH), the promotion and/or improvement of healing of difficult-to-heal wounds was compared in a prospective, parallel-group multicenter, randomized, observer-blinded, controlled trial ("MACAON"). Non-hospitalized patients with pressure, venous or diabetic foot-ulcers difficult-to-heal were recruited and treated with standard care, and EHO-85 (n = 35) or VariHesive (n = 34) as SH. Wound-area reduction (WAR; percentage) and healing rate (HR; mm2/day) were measured. EHO-85 showed a statistically significant superior effect over VariHesive. At the end of the follow-up period, the relative WAR decreased by 51.6% vs. 18.9% (p < 0.001), with a HR mean of 10.5 ± 5.7 vs. 1.0 ± 7.5 mm2/day (p = 0.036). EHO-85 superiority is probably based on its optimal ability to balance the ulcer bed, by modulating pH and oxidative stress. That complements the wetting and barrier functions, characteristics of conventional hydrogels. These results support the use of EHO-85 dressing, for treatment of hard-to-heal ulcers. Trial Registration AEMPS:PS/CR623/17/CE.

Intra-Observer and Inter-Observer Reliability of Ankle Circumference Measurement in Patients with Diabetic Foot: A Prospective Observational Study.

Inflammation, being a typical response to vascular tissue alterations, induces variations in tissue oxygen diffusion pressure. Diabetic microangiopathy, an inflammatory process, is characterized by an increase in vascular flow at rest, reduced venous and arteriolar responses, and increased capillary permeability, resulting in oedema development, decreased transcutaneous oxygen pressure, and increased transcutaneous carbon dioxide pressure. This phenomenon potentially hampers ulcer healing. Although the figure-of-eight method has proven to be a reliable, valid, quick, and efficient test for assessing foot and ankle measurements in patients with oedema and compromised skin integrity, it has not been studied in patients with diabetic foot. The aim of this study was to determine and compare the intra- and inter-observer variabilities of the figure-of-eight method in patients with diabetic foot. A prospective observational and cross-sectional study was undertaken, involving sixty-one subjects from a specialized Diabetic Foot Unit. Three investigators with varying levels of experience independently measured the subjects to assess both intra-observer and inter-observer variability. The evaluation was conducted using the Intraclass Correlation Coefficient (ICC). In the statistical analysis, an ICC of 0.93, adjusted using a 95% confidence interval (CI), was obtained for inter-observer reliability ICC, indicating excellent reliability among observers. Furthermore, an ICC of 0.98 with a 95% CI was obtained for the intra-observer reliability analysis, indicating excellent reliability. The results support using this test during the clinical management of oedema in patients with diabetic foot. The absence of an objective, fast, and readily available diagnostic method for oedema in diabetic foot patients in clinical practice might pose a limitation. Subsequent research should tackle this issue and explore the correlation between ankle perimeter measurements and other clinical outcomes in diabetic foot patients, including wound healing and quality of life.

Cryotherapy versus topical nitric-zinc complex solution for the treatment of plantar warts: A randomized controlled trial.

Cryotherapy is commonly regarded as the primary treatment method for plantar warts. A new medical device called nitric-zinc complex solution (NZCS) has also emerged as a potential alternative for wart treatment. The main aim of this study was to analyze and compare the effectiveness of cryotherapy using liquid nitrogen and NZCS in treating plantar warts. We conducted a randomized and controlled clinical trial involving patients with plantar warts. A total of 62 patients were enrolled in the study and monitored for 12 weeks or until their warts were completely resolved. The patients received either cryotherapy or NZCS, with a maximum of six treatment applications. The cure rate was 65.5% in the group treated with cryotherapy and 56.6% in the group treated with NZCS. The average number of treatment applications required for curing warts was significantly lower in the cured group (3.28 ± 1.63) than in the group with unresolved warts (5.5 ± 1.27) (p < 0.01). Moreover, the average number of applications was lower in the cryotherapy group (3.6 ± 1.8) than in the NZCS group (4.8 ± 1.8) (p < 0.01). Based on the findings, NZCS could be considered a favorable first-line treatment option for plantar warts.

Comparative Analysis of Bone Resection Versus Bone Curettage in Diabetic Foot Osteomyelitis.

This study aims to describe the healing times of patients who underwent bone resection compared to bone curettage for managing diabetic foot osteomyelitis and to compare short- and long-term complications. This analytical retrospective observational cohort study collected clinical records of patients from a specialized diabetic foot clinic who underwent resection or bone curettage between January 2017 and January 2022. After surgery, a 1-year follow-up was conducted to record healing times and short- and long-term complications. The study included thirty-one patients, with 19 (61.29%) undergoing resections and 11 (38.71%) undergoing bone curettages. The resection cohort had a mean healing time of 5.70 ± 6.05 weeks, whereas the curettage cohort had a mean healing time of 14.45 ± 11.78 weeks, showing a statistically significant difference (P = 0.011). No significant differences were observed in terms of short- and long-term complications. In the resection cohort, 12 (63.20%) experienced short-term complications, compared to eight (66.70%) in the curettage cohort (P = 0.842, χ2 = 0.40, OR = 1.16). In the resection cohort, n = 6 (31.60%) had long-term complications, while n = 3 (25.00%) in the curettage cohort experienced long-term complications (P = 0.694, χ2 = 0.155, OR = 0.72). Although there were no significant differences in short- and long-term complications between resection and curettage, the resection group showed shorter healing times.

Analyses of transcutaneous oxygen pressure values stratified for foot angiosomes to predict diabetic foot ulcer healing.

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.

Analysis of the Influence of Diabetic Nephropathy in Patients with Diabetic Foot Osteomyelitis.

This study analyzed the influence of diabetic nephropathy on the healing prognosis after conservative surgery in diabetic foot osteomyelitis (DFO). A retrospective observational study was carried out between January 2021 and December 2022 and involved 278 outpatients with a diagnosis of DFO at a specialized diabetic foot unit, including 74 (26.62%) patients with DN (group 2) and 204 (73.38%) patients without DN (group 1). There were 266 (95.70%) ulcers on the forefoot, 8 (2.90%) on the midfoot, and 4 (1.45%) on the hindfoot (p = 0.992). The healing rates were 85.1% (n = 63) for group 2 and 81.3% (n = 165) for group 1 (p = 0.457). When exploring the influence of DN on the risk of delayed ulcer healing, the results did not show a significant effect [12 (6; 28) weeks among patients with DN vs. 12 (6; 21) weeks among patients without DN; p = 0.576]. No significant differences were observed in complications, with one (2.59%) death occurring in group 1 (p = 0.296) and three minor amputations being performed in both groups [two (5.13%) amputations in group 1 vs. one amputation (9.09%) in group 2; p = 0.217]. Bone cultures were performed for a total of 190 patients (133 in group 1 and 57 in group 2). Of these, 176 positive bone cultures were isolated: 71 positive bone cultures (57.7%) were monomicrobial cultures in group 1, with 30 (56.6%) in group 2. There were 52 (42.3%) that had at least two microorganisms in group 1, and 23 (43.4%) in group 2 (p = 0.890). The most frequently prescribed oral antibiotic was amoxicillin/clavulanate (43.89%), followed by levofloxacin (28.4%), and trimethoprim/sulfamethoxazole (14.7%). This study shows that DN does not have a significant influence on the healing prognosis of patients with DFO after conservative surgery.

Microbiological culture combined with PCR for the diagnosis of onychomycosis: Descriptive analysis of 121 patients.

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.

Is the Combination of Plain X-ray and Probe-to-Bone Test Useful for Diagnosing Diabetic Foot Osteomyelitis? A Systematic Review and Meta-Analysis.

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.

Usability of Different Methods to Assess and Improve Adherence to Therapeutic Footwear in Persons with the Diabetic Foot in Remission. A Systematic Review.

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.

EHO-85, Novel Amorphous Antioxidant Hydrogel, Containing Olea europaea Leaf Extract-Rheological Properties, and Superiority over a Standard Hydrogel in Accelerating Early Wound Healing: A Randomized Controlled Trial.

Many advanced wound healing dressings exist, but there is little high-quality evidence to support them. To determine the performance of a novel amorphous hydrogel (EHO-85) in relation to its application, we compared its rheological properties with those of other standard hydrogels (SH), and we assessed the induction of acceleration of the early stages of wound healing as a secondary objective of a prospective, multicenter, randomized, observer-blinded, controlled trial. The patients were recruited if they had pressure, venous, or diabetic foot ulcers and were treated with EHO-85 (n = 103) or VariHesive® (SH) (n = 92), and their response was assessed by intention-to-treat as wound area reduction (WAR (%)) and healing rate (HR mm2/day) in the second and fourth weeks of treatment. Results: EHO-85 had the highest shear thinning and G'/G″ ratio, the lowest viscous modulus, G″, and relatively low cohesive energy; EHO-85 had a significantly superior effect over SH in WAR and HR, accelerating wound healing in the second and fourth weeks of application (p: 0.002). This superiority is likely based on its optimal moisturizing capacity and excellent pH-lowering and antioxidant properties. In addition, the distinct shear thinning of EHO-85 facilitates spreading by gentle hand pressure, making it easier to apply to wounds. These rheological properties contribute to its improved performance.
