Objective: To determine major risk factors and management outcome of diabetic foot ulcers in order to prevent amputation.
Study Design: Cross-sectional descriptive study.
Place And Duration Of Study: Study was conducted at the Department of Medicine, Civil Hospital Karachi, from January 2005 to December 2006.
Patients And Methods: One-hundred and sixteen consecutive diabetic patients, with foot ulcers of Wagner's grade 1 to 4 were assessed at baseline for demographic information, detailed history, neuropathy, peripheral pulses and frequency of diabetic complication. Glycemic control was determined on the basis of HbA1c levels. Appropriate medical and surgical treatments were carried out and patients were followed-up until healing or for 6 months as end point of study. Outcome was recorded as healed, incomplete healing and amputated.
Results: A majority of subjects had type 2 diabetes (95.7%) with male predominance (66%). The mean age was 54.29 +/- 7.71 years. Most of the patients were overweight, hyperglycemic and had diabetes > 10 years duration. Neuropathic ulcers were found in 91 (78.4%) patients, while rest of the 25 (22.6 %) had neuroischemic ulcers. Wound cultures revealed polymicrobial organisms. Foot ulcers of 89 (77.7%) patients healed without amputation and 17 (14.7%) patients had minor or major amputations. Long-duration of diabetes, poor glycemic control and type of foot ulcers had effect on prognosis (p<0.05).
Conclusion: Effective glycemic control, optimal wound care, aggressive medical management and timely surgical intervention may decrease disabling morbidity with better outcome of diabetic foot ulcer.

Introduction Diabetes is a rapidly growing global health concern, with the World Health Organization (WHO) estimating that 300 million adults will have diabetes by 2025. This chronic condition is associated with complications, including nephropathy, retinopathy, neuropathy, cardiovascular disease, and diabetic foot ulcers (DFUs), which can lead to amputation. Diabetic septic foot (DSF), a severe form of diabetic foot disease, is defined by the WHO as the presence of infection, ulceration, or tissue destruction in the lower limb, often accompanied by neurological abnormalities, peripheral vascular disease, and metabolic complications of diabetes.

Infections caused by persistent, drug-resistant bacteria pose significant challenges in inflammation treatment, often leading to severe morbidity and mortality. Herein, the photosensitizer rhodamine derivatives are selected as the light-trapping dye and the electron-rich substituent N-nitrosoaminophen as the nitric oxide (NO)-releasing component to develop a multifunctional (deep) red-light activatable NO photocage/photodynamic prodrug for efficient treatment of wounds and diabetic foot infections. The prodrug, RhB-NO-2 integrates antimicrobial photodynamic therapy (aPDT), NO sterilization, and NO-mediated anti-inflammatory properties within a small organic molecule and is capable of releasing NO and generating Reactive oxygen species (ROS) when exposed to (deep) red laser (660 nm).

Nerve aberrations and vascular lesions in the distal lower limbs are the etiological factors for diabetic foot ulcers (DFUs). This study aimed to understand the regulatory mechanism of angiogenesis in patients with DFU by examining lncRNA, as well as to explore effective targets for diagnosing and treating DFU. The serum levels of A1BG-AS1 and miR-214-3p and the predictive power of A1BG-AS1 for DFU were determined by quantitative PCR and ROC analysis.

Objectives: This study aims to examine the association between state Medicaid coverage of podiatry services and the outcomes of beneficiaries with new diabetic foot ulcers (DFUs).
Methods: Medicaid beneficiaries who developed a DFU between 2010 and 2015 were identified using the PearlDiver claims database. The states were categorized into covered states (CS) and non-covered states (NCS) based on podiatric coverage during the study period.

Diabetic foot infections (DFIs) are a significant complication in diabetes mellitus, leading to increased morbidity, hospitalizations, and healthcare burdens. The growing prevalence of antibiotic-resistant pathogens has reduced the efficacy of conventional treatments, highlighting the need for alternative therapeutic strategies. Natural products, known for their antimicrobial, anti-inflammatory, and wound-healing properties, have garnered attention as potential treatments for DFIs.
