Purpose: To train and validate machine learning-derived clinical decision algorithm (CDA) for the diagnosis of hyperfunctioning parathyroid glands using preoperative variables to facilitate surgical planning.

Methods: This retrospective study included 458 consecutive primary hyperparathyroidism (PHPT) patients who underwent combined 4D-CT and sestamibi SPECT/CT (MIBI) with subsequent parathyroidectomy from February 2013 to September 2016. The study cohort was divided into training (first 400 patients) and validation sets (remaining 58 patients).

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.

Single ventricle palliation in congenitally corrected transposition of the great arteries: An international multicenter study.

Background: Single ventricle palliation may be performed in patients with congenitally corrected transposition of the great arteries due to hypoplasia of 1 ventricle or anatomic complexity rendering biventricular repair unfeasible. There have been only a few small studies of the outcomes of single ventricle palliation in the setting of congenitally corrected transposition of the great arteries.

Methods: A multicenter, international, retrospective cohort study of patients with congenitally corrected transposition of the great arteries undergoing single ventricle palliation was conducted in 29 tertiary hospitals in 6 countries from 1990 to 2018.

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.
