Improving the regeneration of the tendon-bone interface (TBI) helps to decrease the risk of rotator cuff retears after repair surgeries. Unfortunately, the lack of inherent healing capacity of the TBI, insufficient mechanical properties, and abnormal and persistent inflammation during repair are the key factors leading to suboptimal healing of the rotator cuff. Therefore, a high-strength rotator cuff repair material capable of regulating the unbalanced immune response and enhancing the regeneration of the TBI is urgently needed.

Blood-contacting medical devices can easily trigger immune responses, leading to thrombosis and hyperblastosis. Constructing microtexture that provides efficient antithrombotic and rapid reendothelialization performance on complex curved surfaces remains a pressing challenge. In this work, we present a robust and regular micronano binary texture on the titanium surface, characterized by exceptional mechanical strength and precisely controlled wettability to achieve excellent hemocompatibility.

Orthopaedic Surgery in the Jehovah's Witness Patient: Clinical, Ethical, and Legal Considerations.

J Bone Joint Surg Am

January 2025

Department of Orthopedic Surgery, Warren Alpert Medical School, Brown University, Providence, Rhode Island.

➢ Jehovah's Witnesses refuse allogeneic blood products based on religious beliefs that create clinical, ethical, and legal challenges in orthopaedic surgery, requiring detailed perioperative planning and specific graft selection.➢ Detailed perioperative planning is particularly important for procedures with high intraoperative blood loss.➢ Graft selection must align with Jehovah's Witnesses patients' religious beliefs, with options including autografts, allografts, and synthetic materials; this requires shared decision-making between the patient and surgeon.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.

Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.

Background: An accurate knowledge of a patient's risk of cord-level intraoperative neuromonitoring (IONM) data loss is important for an informed decision-making process prior to deformity correction, but no prediction tool currently exists.

Methods: A total of 1,106 patients with spinal deformity and 205 perioperative variables were included. A stepwise machine-learning (ML) approach using random forest (RF) analysis and multivariable logistic regression was performed.

Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.

Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.

Prcis: Trabecular cutting minimally invasive glaucoma surgery like bent ab interno needle goniectomy (BANG) when performed in baseline aqueous angiography identified low aqueous humor outflow regions, results in greater success of intraocular pressure reduction.

Purpose: To study the efficacy of Bent Ab Interno Needle Goniectomy (BANG) in high versus low aqueous humor outflow (AHO) regions as determined by Aqueous Angiography(AA) in patients with primary open angle glaucoma (POAG).

Methods: A prospective, single-centre, pilot, randomized control trial recruited 30 eyes of 30 patients of POAG and visually significant cataract (45-80 y) and were randomised into two groups ("A": BANG performed in the high-flow regions and "B": BANG performed in the low-flow regions) of 15 each.

Giant cell tumors (GCTs) are benign but locally aggressive bone neoplasms that primarily affect skeletally mature individuals. They are characterized by a tendency for recurrence and being associated with significant morbidity. Traditional treatment has focused on surgical resection; however, the role of medical therapies, such as Denosumab, a bone anti-resorptive drug, which has been Food and Drug Administration (FDA)-approved for unresectable GCTs since 2013, recently has gained prominence.

Background: Blood loss during liver transplantation (LT) remains a major concern associated with increased morbidity and reduced patient and graft survival. The high complexity of the procedure associated with the multifaceted origin of the bleeding urges early identification of high-risk patients and proper monitoring of hemostasis disorders in order to improve results. The accuracy of international normalized ratio (INR) and activated partial thromboplastin time (aPTT) to evaluate coagulation status in cirrhotic patients has been doubted.

Unlabelled: Guided bone regeneration (GBR) is an alternative treatment for craniofacial bone defects reconstruction through membrane barrier adaptation, such as demineralized dentin material membrane (DDMM). DDMM is used as a substitute for GBR material, which aligns with Green Economy principles, it has a good biological osteoinductive and osteoconductive effects, and its structure resembles bones. The balance of bone remodeling when experiencing craniofacial defects will be altered and allow changes to resorption activity, so the mechanisms of osteoclastogenesis and bone resorption are vital.

Three-dimensional measurement of the depth of invasion in oral squamous cell carcinoma samples using Lugol's iodine-enhanced micro-computed tomography: an original study.

J Appl Oral Sci

January 2025

Nanjing University, Research Institute of Stomatology, Affiliated Hospital of Medical School, Nanjing Stomatological Hospital, Department of Oral and Maxillofacial Trauma Orthognathic Plastic Surgery, Nanjing, China.

Objectives: Depth of invasion (DOI) in oral squamous cell carcinoma (OSCC) guides treatment and prognosis but lacks three-dimensional (3D) insight. Thus, this study aimed to investigate the feasibility and accuracy of Lugol's iodine-enhanced micro-computed tomography (CT) for the 3D measurement of DOI in OSCC samples.

Methodology: In total, 50 in vitro OSCC samples from Nanjing Stomatological Hospital (July 2022 to January 2024) were subjected to micro-CT imaging with a slice thickness of 50 μm following 3% Lugol iodine staining for 12 h, followed by pathological examination and staining.
