PURPOSE: Patients with multiple endocrine neoplasia type 1 (MEN1) are predisposed to develop duodenopancreatic neuroendocrine tumors (dpNETs), and metastatic dpNET is the primary cause of disease-related mortality. Presently, there is a paucity of prognostic factors that can reliably identify patients with MEN1-related dpNETS who are at high risk of distant metastasis. In the current study, we aimed to establish novel circulating molecular protein signatures associated with disease progression.

EXPERIMENTAL DESIGN: Mass spectrometry-based proteomic profiling was conducted on plasmas procured through an international collaboration between MD Anderson Cancer Center, the National Institutes of Health, and the University Medical Center Utrecht from …

Finite Element Analysis Comparing A Peek Posterior Fixation Device Versus Pedicle Screws For Lumbar Fusion, Robert Eastlack, Pierce Nunley, Kornelis Poelstra, Alex Vaccaro, Marcus Stone, Larry Miller, Pierre Legay, Julien Clin, Aakash Agarwal

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: Pedicle screw loosening and breakage are common causes of revision surgery after lumbar fusion. Thus, there remains a continued need for supplemental fixation options that offer immediate stability without the associated failure modes. This finite element analysis compared the biomechanical properties of a novel cortico-pedicular posterior fixation (CPPF) device with those of a conventional pedicle screw system (PSS).

METHODS: The CPPF device is a polyetheretherketone strap providing circumferential cortical fixation for lumbar fusion procedures via an arcuate tunnel. Using a validated finite element model, we compared the stability and load transfer characteristics of CPPF to intact conditions under a …

Department of Neurosurgery Faculty Papers

The optimal treatment for intractable epistaxis is still controversial. Various studies have demonstrated high success rates and low complication rates for endovascular embolization. Herein, the authors report an institutional experience and meta-analysis in terms of efficacy and safety of endovascular embolization of intractable epistaxis. This was a retrospective observational study of 35 patients with epistaxis who underwent 40 embolization procedures between 2010 and 2023. The primary outcome was immediate success defined by immediate cessation of epistaxis at the end of the procedure. Immediate success was achieved in most of the procedures (39, 97.5%). During follow-up, three (7.5%) patients experienced a …

Utilization And Short-Term Outcomes Of Percutaneous Left Atrial Appendage Occlusion In Patients With Cancer, Yaqi Zhang, Zhuoran Yang, Muhammad Usman Almani, Raquel Soon-Shiong, Bolun Liu

Einstein Health Papers

Background

Percutaneous left atrial appendage occlusion (LAAO) has been rapidly evolving since FDA’s approval in 2015 and has become more of a same-day-discharge procedure. Cancer patient with atrial fibrillation/flutter (AF) population can benefit from the procedure but the in-hospital outcomes and readmission data were rarely studied.

Objectives

We investigated the utilization, in-hospital and readmission outcomes in cancer patients with AF who underwent LAAO.

Methods

Data were derived from the National Inpatient Sample and National Readmissions Database from 2016 to 2019. Patients with primary diagnosis of AF admitted for LAAO (ICD-10 code 02L73DK) were grouped by cancer as a secondary diagnosis. …

Informed Consent In Surgical Practice With Patients’ Experiences: A Cross-Sectional Study, Seda Kumru, Pakize Yiğit, Meryem Demirtaş, Hüseyin Fındık

Patient Experience Journal

This study aims to evaluate patients' experiences and perspectives regarding informed consent in surgical practice. Data for this cross-sectional study were collected from 276 patients using a questionnaire developed by Falagas et al. Descriptive statistics were employed for all questions. Statistical tests such as the Mann-Whitney U test, Kruskal-Wallis test, and Spearman's rank correlation analysis were performed, and Cohen's effect sizes were reported. IBM SPSS 23.0 was used for all analyses, and p<0.05 was considered statistically significant. A high score on both The Delivered Information Index and The Patient-Physician Index represents a positive informed consent process. Among the participants, 65.2% indicated that they understood all parts of the consent form. Of all patients, 92.8% reported that information about the specific surgical procedure was provided by physicians. However, 47.5% of the patients reported that they did not feel comfortable with their surgeons. The mean score of the Delivered Information Index was 5.63 (2.38). The mean patient-physician relationship score was 14.38 (3.31). There was a moderate positive correlation between the delivered information index and the patient-physician relationship (r=0.50; p<0.001). In addition, there was a moderate positive correlation between the delivered information index and the time spent on the informed consent process, as well as between the patient-physician relationship and the time spent on the informed consent process (r=0.52; r=0.40, respectively). The study emphasized the lack of communication between patients and physicians, the limitation of information on treatment risks, adverse effects, and alternative treatment options.

Resilience Of Patients Undergoing Knee And Shoulder Arthroscopy Procedures, Jillian Mazzocca, Natalie Lowenstein, Connor Crutchfield, Jamie Collins, Elizabeth Matzkin

Student Papers, Posters & Projects

INTRODUCTION: Resilience is a person's capacity to overcome adversity. The purpose was to determine what patient factors correlate with resilience using the Brief Resilience Score. We hypothesize that characteristics of female sex, younger age, Workers' Compensation status, and preoperative opioid use are predictors of a lower preoperative resilience score and that patients with positive psychosocial factors would have higher resilience scores.

METHODS: Eight hundred nine patients undergoing knee or shoulder arthroscopy were preoperatively categorized into low, normal, and high-resilience groups. Preoperative patient-reported outcome measures (PROMs) and demographics were assessed. Statistical analyses evaluated differences in demographics and PROMs between resilience groups. …

Phenytoin-Induced Cerebellar Atrophy: A Case For Reversibility Of Neurological Decline, Edwin Mogere, Davis Cheruiyot, Manakhe Nassiuma

General Surgery, East Africa

This case serves as a reminder of the infrequent, yet consequential occurrence of cerebellar degeneration linked to phenytoin usage. Whilst emphasizes the importance of monitoring patients on long-term phenytoin therapy, and it further suggests considering employing bedside imaging tools such as Ultrasound fusion imaging for follow-up of patients at risk of this type of disorder. We present a case study involving a 23-year-old woman who experienced significant neurological impairment resulting in severe cerebellar atrophy while undergoing phenytoin treatment. On cessation of phenytoin, the patient exhibited improvement with enhanced cerebellar function.

Anterior Cervical Discectomy And Fusion After Presentation To The Acute Care Setting: A Comparison Of Post-Operative Outcomes, Alex Miller, James Whaley, Daniel Park

Conference Presentation Abstracts

Introduction: For patients presenting with cervical radiculopathy or cervical myelopathy, surgical treatment is typically pursued after discussion in the outpatient setting. Yet, there exists a group of patients presenting to the acute care setting with intractable pain or progressive neurologic deficits who are indicated for operative treatment outside of outpatient evaluation. Given the differences in initial management and pre-operative optimization, it is unclear if surgical and post-operative outcomes differ between these populations. Materials and Methods: This was a retrospective cohort study from an academic medical center. Surgical case logs from the institution’s electronic medical record were used to identify patients …
