Noninvasive laboratory testing was used to predict successful amputation levels in 150 diabetic patients. The cases of 100 patients undergoing forefoot amputation and 50 patients undergoing below-knee amputation were evaluated using segmental systolic pressures and pulse volume recordings (PVRs). The decision for and the level of amputation were based solely on clinical judgment. In patients undergoing forefoot amputation, segmental systolic pressures were falsely high or predicted incorrectly in over half the cases. Segment PVRs were correctly predictive in only half of the cases. In patients undergoing below-knee amputation, segment systolic pressures were falsely high or predicted incorrectly in over one third of cases. Segmental PVRs were correctly predictive in less than one third of the cases. In the diabetic patient, clinical judgment continues to provide the most accurate and reliable information by which the type of amputation and likelihood of its success can be judged.

A randomized controlled trial: Effects of compression therapy combined with exercise on chemotherapy-induced peripheral neuropathy in patients with breast cancer.
Cancer Treat Res Commun
January 2025
North China University of Science and Technology, Tangshan 063210, China.
Purpose: To investigate the effects of compression therapy combined with exercise for cancer patients (EXCAP) in patients with peripheral neuropathy caused by breast cancer chemotherapy.
Methods: Overall, 108 patients with peripheral neuropathy after chemotherapy for breast cancer were randomly divided into the control group (routine nursing), experimental group 1 (compression therapy), and experimental group 2 (compression therapy and EXCAP). The National Institute of Cancer Drug Toxicity Rating Scale and the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool were assessed and compared between groups.
Reducing Surgical Site Infections With Silver Impregnated Dressings in Lower Extremity Bypass Patients.
J Surg Res
January 2025
Department of Surgery, Albany Medical Center, Albany, New York; Division of Vascular Surgery, Albany Medical Center, Albany, New York.
Introduction: Surgical site infection (SSI) after lower extremity (LE) bypass surgery is associated with longer length of stay, higher hospital cost, increased morbidity, and even graft loss. Silver impregnated dressings have been used by other surgical subspecialties to decrease SSI with reported success. The National Surgical Quality Improvement Program (NSQIP) published a national expected rate of 7.

Clin Orthop Relat Res
January 2025
Division of Orthopaedic Surgery, University of Toronto, Toronto, ON, Canada.
Background: There is debate as to whether kinematic TKA or mechanical alignment TKA is superior. Recent systematic reviews have suggested that kinematically aligned TKAs may be the preferred option. However, the observed differences in alignment favoring kinematic alignment may not improve outcomes (performance or durability) in ways that patients can perceive, and likewise, statistical differences in outcome scores sometimes observed in clinical trials may be too small for patients to notice.

J Low Genit Tract Dis
January 2025
Department of Obstetrics and Gynecology, University of Ulsan College of Medicine, Asan Medical Center, Seoul, Republic of Korea.
Objective: The aim of the study was to evaluate the hemostatic efficacy of the fibrin sealant patch (TachoSil) after loop electrosurgical excision (LEEP) and its influence on other complications and quality of life (QoL).
Materials And Methods: This single-blind, prospective, randomized study involved patients undergoing LEEP with or without TachoSil (1:1) between August 2014 and August 2015 in Asan Medical Center, Korea. Primary outcome measures were bleeding duration and the frequency of additional treatment owing to vaginal bleeding within 2 weeks after LEEP.
Does Resilience Change in Patients Undergoing Shoulder Surgery? A Retrospective Comparative Study Utilizing the Brief Resilience Scale.
Clin Orthop Relat Res
January 2025
Department of Orthopaedic Surgery, Mayo Clinic, Phoenix, AZ, USA.
Background: Resilience refers to the ability to adapt or recover from stress. There is increasing appreciation that it plays an important role in wholistic patient-centered care and may affect patient outcomes, including those of orthopaedic surgery. Despite being a focus of the current orthopaedic evidence, there is no strong understanding yet of whether resilience is a stable patient quality or a dynamic one that may be modified perioperatively to improve patient-reported outcome scores.
