Machine learning survival models for colorectal cancer: advantages of random survival forests over classification algorithms

Colorectal cancer remains a major cause of cancer-related mortality worldwide, motivating the development of accurate prognostic models. Despite advances in machine learning for survival prediction, a common practice in the literature reformulates time-to-event outcomes as binary...

Development and Reliability Testing of the Sinonasal Assessment of Reepithelialization, a Novel Wound Healing Scale to Assess Postoperative Healing

ABSTRACT Background Sinus and skull base surgery create areas of demucosalized bone and cartilage in the sinonasal cavity, yet no standardized system exists to describe the progressive healing of these wounds. The goal of this study was to develop the novel Sinonasal Assessment o...

Comparative Clinical Effectiveness and Operating Efficiency of Different Ultrasonic Devices for Performance of Sleeve Gastrectomy

INTRODUCTION: This study aims to evaluate clinical and economic outcomes of using different ultrasonic energy devices in patients undergoing sleeve gastrectomy (SG). METHODS: The patient cohort was extracted from PINC AI™ Healthcare Data 2019-2023, including individuals aged ≥ 18...

Neural dynamics underlying minute-timescale persistent behaviour in the human brain

Pursuing longer-term goals relies on representations of task context that can be maintained over long periods of time and switched flexibly when goals change. Little is known about the neural substrate for maintaining context representations on the minute-timescale on which human...

Stereotactic Body Radiotherapy vs Moderately Hypofractionated IMRT for Localized Intermediate-Risk Prostate Cancer

Importance The treatment of prostate cancer with radiotherapy is evolving. How quickly radiotherapy can be delivered, and the relative risks and benefits of such a treatment, is of significant public interest. Objective To determine whether stereotactic body radiotherapy (SBRT) w...

Association of high birth weight with risk of early-onset colorectal cancer

BACKGROUND: Early-onset colorectal cancer (eoCRC), particularly rectal cancer, is increasing. We evaluated the association between high birth weight and eoCRC in a nested case-control study. METHODS: We included patients aged 15-49 years diagnosed with colorectal adenocarcinoma a...

How low do you need to go? Association between various prostate‐specific antigen response measures and clinical outcomes in metastatic castration‐sensitive prostate cancer in the Veterans Health Administration data

BACKGROUND: Multiple phase 3 metastatic castration-sensitive prostate cancer (mCSPC) studies consistently show a prostate-specific antigen (PSA) nadir of <0.2 ng/mL to be the preferred threshold for PSA response. However, in real-world practice, physicians often use other metrics...

Human iPSC-based skeletal muscle model of LAMA2-related congenital muscular dystrophy

Congenital muscular dystrophies (CMDs) are rare, devastating pediatric conditions with no specific treatment or cure. The most common form, LAMA2-related CMD, or LAMA2-CMD (previously known as merosin-deficiency and MDC type 1 A), is caused by myofiber instability from loss of th...

Novel Explantation Protocol for Cardiac Recovery and Device Weaning Post-Left Ventricular Assist Device Therapy: A Single-Center Experience

Although some patients may exhibit significant myocardial improvement after the placement of a durable left ventricular assist device (LVAD), there are no established guidelines on determining patients who may be eligible for explantation. In this single-center case series, three...

Pre-trained knowledge transfer with application in multisystem inflammatory syndrome subphenotyping in children

Multisystem inflammatory syndrome in children (MIS-C) is a severe post-acute sequela of SARS-CoV-2 infection in children and presents with highly heterogeneous signs and symptoms. Disentangling the clinical manifestations of MIS-C by characterizing its subphenotypes can help iden...

Frailty and Surgical Invasiveness Are Independently Associated with Complications in Pediatric Spinal Deformity Surgery

Background: The purposes of this study were to determine whether frailty and surgical invasiveness are independently associated with perioperative outcomes and to describe the outcome rates when these 2 risk domains are considered together in pediatric patients undergoing spinal...

Effect of time to palliative epilepsy surgery on outcomes

Abstract Objective Epilepsy duration is a modifiable risk factor in the outcome of definitive epilepsy surgery; however, an analogous effect in palliative procedures has not been shown. We reviewed the Pediatric Epilepsy Surgery Database data for an association between epilepsy d...

The cost-effectiveness of biosimilar denosumab in postmenopausal osteoporosis: implications of baseline fracture risk and drug price

Biosimilar denosumab is a dominant treatment strategy (i.e., more effective and less costly) across varying levels of baseline fracture risk with sufficient price reductions. Given its superior efficacy and safety, it may be considered a first-line therapy for the treatment of wo...
