Revascularization prevents amputation among patients with diabetic foot during the COVID-19 era.

Objective: The COVID-19 pandemic has led to significant changes in healthcare systems that impact the management of chronic diseases such as diabetic foot (DF). We hypothesized that lack of access to healthcare would increase the severity of disease and lead to worse outcomes.

Methods: The medical records of patients with DF were reviewed to determine demographic data and outcomes including wound healing, major amputation (MA), and death.

Oncological Implications of Lymph Nodes Retrieval and Perineural Invasion in Colorectal Cancer: Outcomes from a Referral Center.

Background: In colorectal cancer (CRC), regional lymphadenectomy provides prognostic information and guides management. The current consensus states that at least 12 lymph nodes (LN) should be evaluated. The aims of this study were to identify whether the number of LN is a predictor for survival and recurrence, and to reveal the role of LN ratio (LNR) and perineural invasion (PNI) in predicting prognosis after curative resection of CRC.
