Safety of prolonged bilateral antegrade cerebral perfusion in aortic arch surgery with moderate hypothermia.

Objectives: This study investigates the impact of bilateral antegrade cerebral perfusion (ACP) time on outcomes in aortic arch surgery.

Methods: In total, 961 patients underwent either hemiarch (n = 385) or total arch replacement (n = 576) with bilateral ACP and moderate hypothermia management between 2006 and 2020 across 2 aortic centres. ACP time was categorized into 4 groups (≤30 min: n = 169, 30-60 min: n = 298, 60-90 min: n = 261, >90 min: n = 233).

Treatment appropriateness of direct oral anticoagulants in patients with atrial fibrillation for stroke prevention: A real-world prospective study.

Introduction: Inappropriate use of direct oral anticoagulants (DOACs) is common, affecting up to 30% of atrial fibrillation (AF) population receiving treatment for stroke prevention. This study assessed appropriateness of anticoagulation in anticoagulation-naive AF patients treated with DOACs during a 12-month prospective follow-up.

Methods: This prospective cohort study included all anticoagulation-naive AF patients referred for anticoagulation for stroke prevention at a tertiary cardiovascular center.

Outcomes of Balloon-Expandable Transcatheter Aortic Valve Replacement in Younger Patients in the Low-Risk Era.

Importance: Guidelines advise heart team assessment for all patients with aortic stenosis, with surgical aortic valve replacement recommended for patients younger than 65 years or with a life expectancy greater than 20 years. If bioprosthetic valves are selected, repeat procedures may be needed given limited durability of tissue valves; however, younger patients with aortic stenosis may have major comorbidities that can limit life expectancy, impacting decision-making.

Objective: To characterize patients younger than 65 years who received transcatheter aortic valve replacement (TAVR) and compare their outcomes with patients aged 65 to 80 years.

COVID-19 and postoperative complications after plastic surgery procedures: More than just hypercoagulability.

Background: Although plastic surgery procedures generally demonstrate less than 2% incidence of venous thromboembolism (VTE) outcomes, the post-COVID era data remain elusive. This study sought to elucidate the relationship between COVID-19 infection and the risk of VTE outcomes across plastic surgery procedures.

Methods: Plastic surgery procedures were identified in the 2012-2022 National Surgical Quality Improvement Program databases.

Pharmacokinetic and Pharmacodynamic Interactions between Food or Herbal Products and Oral Anticoagulants: Evidence Review, Practical Recommendations, and Knowledge Gaps.

Interactions between food and oral anticoagulants (OACs), particularly vitamin K antagonists such as warfarin, are widely recognized and may also be clinically relevant for direct OACs. Pharmacokinetic and pharmacodynamic interactions with food or herbs can lead to anticoagulation potentiation, increased risk of bleeding, or reduced drug efficacy, all compromising patient safety. We conducted a systematic search for randomized controlled trials (RCTs) on PubMed for assessments of interactions between OACs and various ingestants.

BRCA1-associated-protein-1 inactivated melanocytic tumours: characterisation of the clinicopathological spectrum and immunohistochemical expression pattern of preferentially expressed antigen in melanoma.

Aims: BRCA1-associaed protein-1 (BAP1) inactivated tumours (BIMT) are rare melanocytic tumours that may be mistaken for Spitz tumours or melanoma. They occur sporadically or in association with the BAP1 tumour predisposition syndrome (BAP1-TPDS), which may be complicated by uveal or cutaneous melanoma, mesothelioma, basal cell carcinoma and renal cell carcinoma. The aim of this study was to characterise the clinicopathological features and the immunohistochemical expression pattern of preferentially expressed antigen in melanoma (PRAME) of BIMT in a large patient cohort.

The influence of patient sex on pulmonary embolism evaluation, treatment modality, and outcomes.

Background: Pulmonary embolism (PE) is the third-leading cause of cardiovascular mortality, accounting for 100,000 deaths per year in the United States. Although sex-based disparities have previously been described in this population, it is unclear if these differences have persisted with the expansion of PE evaluation and treatment approaches. The purpose of this study is to investigate sex-based differences in the evaluation, management, and outcomes of patients with acute PE.

Education and Training in Global Neurosurgery: Current State and Path Toward a Uniform Curriculum.

Education is a sustainable long-term measure to address the global burden of neurosurgical disease. Neurosurgery residencies in high-income countries are accredited by a regional governing body and incorporate various educational activities. Few opportunities for training may be present in low-income and middle-income countries due to a lack of neurosurgery residency programs, tuition, and health care workforce reductions.

Incretin hormone agonists: Current and emerging pharmacotherapy for obesity management.

Obesity continues to be a significant global health challenge, affecting over 800 million individuals worldwide. Traditional management strategies, including dietary, exercise, and behavioral interventions, often result in insufficient and unsustainable weight loss. Lifestyle modification remains the cornerstone of obesity management, providing the foundation for other strategies.

Pulmonary Cytopathology: Current and Future Impact of Microscopy and Immunohistochemistry.

With the advancement of tissue procurement techniques, in-depth knowledge of morphology is crucial for cytopathologists to diagnose neoplastic and nonneoplastic lung diseases optimally. Cytopathologists must also be well versed in immunohistochemistry/immunocytochemistry markers and their interpretation for an accurate diagnosis.

Pulmonary Cytopathology: Current and Future Impact on Patient Care.

Small biopsies of lung are routinely obtained by many methods, including several that result in cytologic specimens. Because lung cancer is often diagnosed at a stage for which primary resection is not an option, it is critical that all diagnostic, predictive, and prognostic information be derived from such small biopsy specimens. As the number of available diagnostic and predictive markers expands, cytopathologists must familiarize themselves with current requirements for specimen acquisition, handling, results reporting, and molecular and other ancillary testing, all of which are reviewed here.

Surgeon-Applied Stress and a Ligament Tensor Instrument Provide a Similar Assessment of Preresection Flexion Laxity During Robotic Total Knee Arthroplasty.

Background: Robotic-assisted total knee arthroplasty (RA-TKA) allows surgeons to perform intraoperative soft tissue laxity assessments prior to bone resections and is used to alter resections to achieve gap balance. This study compared 2 techniques for flexion gap laxity assessment during RA-TKA.

Methods: A prospective study of 50 primary RA-TKAs performed by a single surgeon was conducted between February and October 2023.

Midterm results for revision total knee arthroplasty for component malrotation.

Introduction: Accurate positioning of components in total knee arthroplasty (TKA) is essential to a satisfactory outcome. Significant malrotation may lead to chronic pain, stiffness, and dysfunction. This study aims to quantify improvements in functional outcomes following revision surgery for malrotation of either one or both components in TKA versus revision for aseptic loosening.

Ivabradine Approved and Other Uses in Clinical Practice: A Systematic Review.

Heart rate (HR) stands as a prognostic indicator of cardiovascular disease and a modifiable risk factor in heart failure (HF). Medication intolerance can curtail the application of conventional HR-lowering β-blockers to the optimum target dose. Ivabradine (IVA), a specific negative-chronotropic agent, selectively inhibits I f current in pacemaker cells of the sinoatrial node without depressing myocardial contractility or comprising hemodynamics.

Calcified Nodule in Percutaneous Coronary Intervention: Therapeutic Challenges.

Calcified nodules (CNs) are among the most challenging lesions to treat in contemporary percutaneous coronary intervention. CNs may be divided into 2 subtypes, eruptive and noneruptive, which have distinct histopathological and prognostic features. An eruptive CN is a biologically active lesion with a disrupted fibrous cap and possibly adherent thrombus, whereas a noneruptive CN has an intact fibrous cap and no adherent thrombus.

Atherosclerosis Is a Smooth Muscle Cell-Driven Tumor-Like Disease.

Background: Atherosclerosis, a leading cause of cardiovascular disease, involves the pathological activation of various cell types, including immunocytes (eg, macrophages and T cells), smooth muscle cells (SMCs), and endothelial cells. Accumulating evidence suggests that transition of SMCs to other cell types, known as phenotypic switching, plays a central role in atherosclerosis development and complications. However, the characteristics of SMC-derived cells and the underlying mechanisms of SMC transition in disease pathogenesis remain poorly understood.
