A longitudinal rat forelimb model for assessing neuromuscular function following extremity reperfusion injury.

Rhabdomyolysis following revascularization of the ischemic upper extremity can lead to life- & limb-threatening sequelae. In the context of replantations and vascularized composite allografting, a reconstructive procedure usually reserved for upper limb amputees, prolonged tissue ischemia is detrimental to extremity functional recovery. Currently, validated survival small animal models of extremity reperfusion injury that permit longitudinal assessment of limb function are lacking.

Validity of the Diabetic Wound Assessment Learning Tool.

Purpose: The development of the Diabetic Wound Assessment Learning Tool (DiWALT) has previously been described. However, an examination of its application to a larger, more heterogeneous group of participants is lacking. In order to allow for a more robust assessment of the psychometric properties of the DiWALT, we applied it to a broader group of participants.

Integrating Physical and Biochemical Cues for Muscle Engineering: Scaffolds and Graft Durability.

Muscle stem cells (MuSCs) are essential for skeletal muscle regeneration, influenced by a complex interplay of mechanical, biochemical, and molecular cues. Properties of the extracellular matrix (ECM) such as stiffness and alignment guide stem cell fate through mechanosensitive pathways, where forces like shear stress translate into biochemical signals, affecting cell behavior. Aging introduces senescence which disrupts the MuSC niche, leading to reduced regenerative capacity via epigenetic alterations and metabolic shifts.

Evaluating the Effectiveness of Commercially Available Antiadhesion Tendon Protector Sheets in Tendon Repair Surgery Versus Tendon Repair Surgery Alone: A Preclinical Model Study.

Purpose: Adhesion formation is the major complication after tendon repairs that halts functional restoration and causes disability in patients. This study aimed to compare the antiadhesion efficacy of two tendon protector sheets using a previously established turkey flexor tendon model.

Methods: Twenty-four adult Bourbon Red turkeys were randomized into three groups: (1) control, (2) type I collagen-glycosaminoglycan (Collagen-GAG), and (3) hyaluronic acid.

Expanded polytetrafluoroethylene mesh in chest-wall reconstruction: A 27-year experience.

Objective: The study objective was to evaluate the success of expanded polytetrafluoroethylene mesh in chest-wall reconstruction.

Methods: We retrospectively reviewed patients who underwent expanded polytetrafluoroethylene (Gore-Tex) chest-wall reconstruction. The main outcome was a mesh-related event, defined as a mesh-related reoperation (eg, mesh infection requiring debridement with/without explant, tumor recurrence with explant) or structural dehiscence/mesh loosening with/without a hernia.

Anticancer effects of thymoquinone in head and neck squamous cell carcinoma: A scoping review.

Objective: Thymoquinone (TQ), the active constituent of , has been shown to have anticancer effects in head and neck squamous cell carcinoma (HNSCC). This review aims to outline the properties of TQ, the known drivers in HNSCC formation, and summarize the anticancer effects of TQ in SCC.

Data Sources: Three databases (PubMed, Embase, and Google Scholar) were queried for the key words "thymoquinone squamous cell carcinoma.

A review of the therapeutic potential of histone deacetylase inhibitors in rhabdomyosarcoma.

This review aims to summarize the putative role of histone deacetylases (HDACs) in rhabdomyosarcoma (RMS) and the effects of HDAC inhibitors (HDACi) on RMS by elucidating and highlighting known oncogenic pathways, mechanisms of resistance, and the synergistic potential of histone deacetylase inhibitors. We searched two databases (PubMed and Google Scholar) for the keywords "Rhabdomyosarcoma, histone deacetylase, histone deacetylase inhibitors." We excluded three publications that did not permit access to the full text to review and those that focus exclusively on pleiomorphic RMS in adults.

Evaluation of the Efficacy of an Online Learning Module to Increase Wound Care Theoretical Knowledge Amongst Medical Students.

Objective: We developed and evaluated an online learning module for teaching wound care basics to junior medical learners, which was assessed for its ability to increase theoretical knowledge of wound care, and medical learners' perceptions on the use of an online module to teach wound care practices.

Design: Between February 2022 to November 2022, participants were enrolled into our unblinded, matched-pair single-arm study. Participants completed a pre- and postquiz prior to and after completing the online module, respectively.

Arthroscopic Simulation: The Future of Surgical Training: A Systematic Review.

Background: Arthroscopic simulation has rapidly evolved recently with the introduction of higher-fidelity simulation models, such as virtual reality simulators, which provide trainees an environment to practice skills without causing undue harm to patients. Simulation training also offers a uniform approach to learn surgical skills with immediate feedback. The aim of this article is to review the recent research investigating the use of arthroscopy simulators in training and the teaching of surgical skills.

Three-Dimensional Engineered Peripheral Nerve: Toward a New Era of Patient-Specific Nerve Repair Solutions.

Reconstruction of peripheral nerve injuries (PNIs) with substance loss remains challenging because of limited treatment solutions and unsatisfactory patient outcomes. Currently, nerve autografting is the first-line management choice for bridging critical-sized nerve defects. The procedure, however, is often complicated by donor site morbidity and paucity of nerve tissue, raising a quest for better alternatives.

Development of the Diabetic Wound Assessment Learning Tool (DiWALT) and validity evidence.

Objective: Diabetic foot wounds account for up to one-third of diabetes-related health care expenditure and are the greatest cause of extremity amputation in Canada. Physicians encounter patients with such wounds in all specialties, particularly as generalists in medical wards and emergency departments. However, there is a dearth of literature on the optimal way to teach and to assess the management of these patients.
