Background: Confusion often arises in caring for diabetic foot infections and ulcers, especially with antimicrobials;we aim to shed light on this entity and alert healthcare workers to its stewardship. Methods: Records were reviewed between February 2016 and September 2023. Data for patients diagnosed with diabetes and foot ulcers, infected or not, were examined following ICD 9 search terms. Records for patients were included if they were prediabetic/diabetic adults with foot ulcers, more than 18 years old, and on antidiabetic treatment. Patients were excluded if they insulin resistant, with normal HgbA1c levels, wheel-chair dependent, bed-bound, non-diabetic patients, diabetic patients who had vascular lower limb surgery earlier to ulcers, diabetic patients who had aortocoronary bypass, deep venous thrombosis within six months, malignancy, and severe clinical depression. A modified IWGDF/IDSA guidelines definitions for DFI and DFU was considered. Statistical analysis was done using R programming. Statistical methods were employed as appropriate, and a significant P-value was considered for P Results: Most characteristics were well balanced between DFI and DFU, on imaging osteomyelitis and tissue swelling were significantly more in DFI. Endovascular radiological procedures showed angiograms to be considerably more in DFI, while angioplasty was more in DFU, in addition to smoking. Bacteremia was uncommon, and swab cultures were mostly polymicrobial in both ulcers;no clear association with blood bacteria was detected with the polymicrobial growth, though few were concordant. Antimicrobials prescribed for both ulcers were not statistically different except for carbapenems, which were more in DFI (P Conclusion: Attention should be paid to best practices while caring for diabetic ulcers. These include swab culture interpretations, the use of antimicrobials, and plan management according to DFI or DFU to utilize either local care or combination with antimicrobials.

The rapid development of data communication in modern era demands secure exchange of information. Steganography is an established method for hiding secret data from an unauthorized access into a cover object in such a way that it is invisible to human eyes. The cover object can be image, text, audio,or video. This paper proposes a secure steganography algorithm that hides a bitstream of the secret text into the least significant bits（LSBs） of the approximation coefficients of the integer wavelet transform（IWT） of grayscale images as well as each component of color images to form stego-images. The embedding and extracting phases of the proposed steganography algorithms are performed using the MATLAB software. Invisibility, payload capacity, and security in terms of peak signal to noise ratio（PSNR） and robustness are the key challenges to steganography. The statistical distortion between the cover images and the stego-images is measured by using the mean square error（MSE） and the PSNR, while the degree of closeness between them is evaluated using the normalized cross correlation（NCC）. The experimental results show that, the proposed algorithms can hide the secret text with a large payload capacity with a high level of security and a higher invisibility. Furthermore, the proposed technique is computationally efficient and better results for both PSNR and NCC are achieved compared with the previous algorithms.
