The aim of the current study was to evaluate the rate of readmission in patients affected by diabetes and foot ulcers (DFUs), and causes and outcomes of patients requiring a new hospitalization. The current study is a retrospective observational study including patients who have required hospitalization since January 2019 to September 2022 due to a DFU. Once patients were discharged, they were regularly followed as outpatients. Within 6 months of follow-up, the rate of hospital readmission for a diabetic foot problem was recorded. According to the readmission or not, patients were divided into 2 groups, readmitted and not readmitted patients, respectively. Hence, all patients were followed for 6 months more and outcomes of the 2 groups were analyzed and compared. Overall, 310 patients were included. The mean age was 68  ±  12 years, the majority of patients reported type 2 diabetes (>90%), and the mean diabetes duration was approximately 20 years. Sixty-eight (21.9%) patients were readmitted. The main reason for hospital readmission was the presence of critical limb ischemia (CLI) in the contralateral limb (6.1%), the recurrence of CLI in the previous treated limb (4.5%), and the onset of new infected DFU in the contralateral foot (4.5%). Readmitted patients reported lower rate of healing (51.5% vs 89.2%, P < .0001) and higher rate of major amputation (10.3% vs 4.5%, P  =  .2) in comparison to not readmitted patients. Critical limb ischemia resulted in the only independent predictor of hospital readmission. Hospital readmission is a frequent issue among patients with DFUs, and readmitted patients showed a lower chance of wound healing. Critical limb ischemia resulted in the main cause of new hospitalization.

Bacterial proliferation plays a well-known role in delayed tissue healing. To date, the presence of microorganisms on the wound bed can be detected by skin swabs or skin biopsies. A novel noninvasive fluorescence imaging device has recently allowed real-time detection of bacteria in different types of wounds through endogenous autofluorescence. The fluorescence signals detected by the device provide health workers with a visual indication of the presence, load, and distribution of bacteria. The aim of our study was to evaluate the level of bacterial colonization in perilesional skin of patients affected by venous leg ulcers treated with 2 different types of bandages: short stretch bandage and zinc oxide bandage. We conducted a monocentric prospective study, enrolling 30 patients with venous leg ulcers, divided into 2 groups: group A was treated with short stretch bandage and group B with zinc oxide bandage. A complete patient's assessment was performed once a week for 3 weeks. Levels of potentially harmful bacteria in perilesional skin were detected using a fluorescent device by 2 experienced operators on the frames taken at individual injuries, while pain was evaluated with the Numerical Rating Scale. After 3 weeks, we observed a reduction in the bacterial colonization levels of the perilesional skin by 68.67% for group A and 85.54% for group B. All the patients had a statistically significant reduction in bacterial load (P < .001), and a statistically significant difference was identified between the 2 groups (P = .043). No statistically significant differences were found between the 2 groups in terms of pain relief (P = .114). Our study demonstrated that the application of zinc oxide bandage provides a higher reduction in bacterial load perilesional skin. On the other hand, we found no difference between the 2 bandages in terms of pain symptom reduction.

Diabetic foot ulcers (DFUs) are classified as hard-to-heal wounds, which occur in approximately 15% of diabetic patients. Several interventions have shown efficacy in reducing the risk of amputation among patients with DFU, including timely diagnosis and management of infection and ischemia, debridement of necrotic tissues, reducing mechanical pressure on ulcers, and patient education. One major challenge in the management of DFUs is optimizing wound care to improve healing outcomes. Recently, interdisciplinary approaches proposed a new generation of wound dressing which increased efficacy and significantly decreased the healing time. The current study assessed the healing characteristics of chronic DFUs treated with lyophilized amniotic membrane gel (LAMG) in combination with standard care, versus a placebo hydrogel with standard care. In total, 18 patients (8 male, 10 female) were randomly assigned to the control group, which received standard care and a gelatin scaffold (placebo), or the intervention group, which received standard care along with LAMG. We evaluated the reduction in wound size and assessed the patient's health-related quality of life over 9 weeks. In the LAMG group (n = 9) and the Placebo group (n = 9), the wounds were reduced in size by a mean of 73.4% ± 15.3% and 13.1% ± 10.1%, respectively (P = .008). Patients treated with LAMG demonstrated significant improvements in the scores related to physical function, physical limitation, physical pain, general health, social function, emotional problems, and energy levels compared to the control group. The findings of this study indicate that using the LAMG with standard care significantly enhances wound healing.

We hypothesized that foot infections secondary to a puncture wounds (PWs) have a worse prognosis concerning infection-related mortality, recurrence of the infection, and healing than those secondary to a chronic ulcer. We conducted a prospective study consisting of 200 patients with moderate-to-severe diabetic foot infections. The cohort consisted of 155 men (77.5%) and 45 women (22.5%). The mean age of the patients was 59 years (standard deviation 12.2). Puncture wounds were the cause of the infection in 107 patients (53.5%) and a chronic ulcer was the cause in 93 patients (46.5%). One hundred and eleven patients (55.5%) had moderate and 89 (44.5%) had severe infections. Osteomyelitis was more frequently found in chronic ulcers (71%) than in PWs (44.9%), P < .001. Cox's survival analysis using PWs as an explanatory variable showed no association with infection-related mortality (hazard ratio [HR] 1.06, 95% confidence interval [CI] 0.32-3.46, P = .92), time to recurrence of infection (HR 0.64, 95% CI 0.27-1.51, P = .30), and time to healing (HR 0.81, 95% CI 0.60-1.08, P = .15). More than half of our patients had PWs as the mechanism by which the infection occurred. These patients usually had a lower rate of osteomyelitis but required hospitalization and antibiotic therapy more frequently than patients with infected chronic ulcers. We found no difference in outcomes between the 2 groups.

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.

Background and aims: Diabetic foot is one of the most severe complications in patients with diabetes mellitus and has been linked to 25-OH-vitamin D status. This study aims to determine the prevalence of 25-OH-vitamin D deficiency and its association with diabetic foot. Methods: Patients with type 2 diabetes mellitus were enrolled in this study. The patients were divided into the diabetic foot group (n = 95) and the non-diabetic foot group (n = 388). Weight, height, and waist circumference were measured. The 25-OH-vitamin D and the other biochemical tests were extracted from the electronic medical records. The difference in clinical parameters between the diabetic foot group and the non-diabetic foot group was analyzed, and the risk factors of the diabetic foot group were analyzed using logistic regression. Results: The prevalence of 25-OH-vitamin D deficiency was 44.6%, accounting for 57.9% of all the diabetic foot group patients and only 41.0% of the non-diabetic foot group patients. The mean serum 25-OH-vitamin D level was significantly different between the diabetic foot group and the non-diabetic foot group (19.8 ± 9.5 vs 24.1 ± 11.8; P = .011). Serum 25-OH-vitamin D and B12 were found to have a significant positive correlation (r = 0.410, P = <.01). The 25-OH-vitamin D level and body mass index were independently associated with diabetic foot (P = .043, OR = 1.21; P = .009, OR =  1.47), respectively. Conclusions: The 25-OH-vitamin D deficiency was higher in the diabetic foot group. More research is needed to understand the role of 25-OH-vitamin D in the development of diabetic foot.

Diabetes mellitus has a global impact, necessitating surgical intervention when conservative methods fail. Transtibial amputation (TTA) is commonly performed on diabetic patients, yet surgical site complications can lead to more procedures. This study aimed to identify factors linked to wound healing issues post-TTA in diabetics.A total of 181 patients who underwent TTA between 2004 and 2021 at a single hospital were included in the study. Exclusion criteria comprised trauma, non-diabetic mellitus, follow-up duration of less than 1 year, incomplete medical records, and surgeries performed by different surgeons. The comparison focused on underlying diseases other than diabetes between the group with wound problems and the group without. Additionally, factors impacting blood flow, such as presurgery hemoglobin levels, intraoperative blood transfusion, the use of antithrombotic or anticoagulant drugs, and the presence of procedures like percutaneous transluminal angioplasty (PTA) and bypass surgery, were analyzed.Among the 181 cases, 22.1% experienced problems at the surgical site while 77.9% did not. Statistical analysis revealed that age was a significant variable affecting wound healing problems after TTA in diabetic patients (p = .007). However, there were no significant differences in wound problems based on comorbidities other than diabetes (p = .209), gender (p = .677), preoperative anemia (p = .102), intraoperative blood transfusion (p = .633), the use of antithrombotic or anticoagulant medications (p = .556), and the performance of PTA or bypass surgery (p = .6).In conclusion, this study found that age was a significant variable affecting wound healing problems after TTA in diabetic patients. Although no association was observed between underlying diseases and wound healing problems, further investigation and cautious management of factors such as preoperative anemia, intraoperative blood transfusion, the use of antithrombotic or anticoagulant drugs, and the performance of PTA or bypass surgery are warranted to prevent complications and optimize wound healing outcomes in diabetic patients undergoing TTA.

Feet suffer significant stress throughout a lifetime and undergo ageing-associated problems due to gradual tissue degeneration affecting the skin, connective tissue, and nerves. Oxygen supply to the tissues may be diminished. The skin gets dry and calluses, ulcers and fungal infections of the skin and nails are not uncommon. Ligaments and tendons degenerate and, without proper prevention, deformities including claw toes, hammer toes, tendonitis, and bursitis may occur. Skeletal toe deformities such as bunions, bony spurs, and hallux valgus may increase discomfort, while stress fractures may have an adverse impact on the patients' quality of life. The ageing foot pathology may add up to common age-related problems, such as crystal deposition arthropathies, diabetes mellitus, peripheral circulatory disorders, and peripheral edema, increasing morbidity. This review summarizes ageing-related feet problems, focusing on prevention and treatment. Foot health has a paramount role in overall wellbeing, therefore prevention, proper foot care, and prompt diagnosis and management of ageing-related changes are vital for maintaining a healthy, active status.
