Gut-derived appetite regulating hormones across the anorexia nervosa spectrum.

Background: Appetite-regulating hormones are implicated in anorexia nervosa (AN) pathophysiology, however, data are limited for appetite-regulating hormones across the AN weight spectrum. We aimed to investigate fasting and post-prandial concentrations of appetite-regulating hormones - peptide YY (PYY), cholecystokinin (CCK), and ghrelin - among adolescent and young adult females across the AN weight spectrum, specifically those with AN and Atypical AN, and healthy controls (HC).

Methods: Participants (N = 95; ages 11-22 years) included 33 with AN, 25 with Atypical AN, and 37 HC.

Characterizing patterns of opioid prescribing after outpatient ventral hernia repair with mesh.

Purpose: Despite efforts to minimize opioid prescribing, outpatient ventral hernia repair (VHR) with mesh remains notoriously painful, often requiring postoperative opioid analgesia. Here, we aim to characterize patterns of opioid prescribing for the heterogenous group of patients and procedures that comprise mesh-based, outpatient VHR.

Methods: The Abdominal Core Health Quality Collaborative registry was queried for patients undergoing VHR with mesh who were discharged the same or next day between January 2019 to October 2023.

Elotuzumab in combination with pomalidomide, bortezomib, and dexamethasone in relapsed and refractory multiple myeloma.

Elotuzumab is an approved monoclonal antibody targeting SLAMF7 on plasma and NK cells that enhances the activity of lenalidomide, pomalidomide, and bortezomib in multiple myeloma (MM). The OPTIMISMM study showed improved outcomes with the combination of pomalidomide, bortezomib, and dexamethasone (PVd) in relapsed/refractory MM. We therefore studied adding elotuzumab to PVd (elo-PVd) in relapsed/refractory MM in a multicenter phase 2 trial.

Three-dimensional kinematic analysis of the cervical spine following posterior atlantoaxial fusion under physiological loading: An in vivo study.

Background: This study aimed to analyze the three-dimensional cervical motion characteristics in patients who underwent posterior atlantoaxial fusion surgeries using cone beam computed tomography and 3D3D registration technology.

Methods: The study selected 20 patients who underwent posterior atlantoaxial fusion surgery and 20 healthy people as the control group. All subjects underwent cone beam computed tomography scans of the occipital and cervical spine in 7 different functional positions, then 3D3D registration of Occipital-C7 was performed at each functional position to calculate the motion characteristics of each segment.

Sex Differences in Opioid-Sparing Regimen Prescribing Following Ventral Hernia Repair.

Introduction: While sex differences are known to have a clinically relevant impact on the response to pain therapy, current data are still largely equivocal on sex-specific postoperative pain management. The aim of this study is to determine whether sex predicts differences in pain management in patients undergoing ventral hernia repair (VHR).

Methods: This was a retrospective analysis of prospectively collected data for VHR from the Abdominal Core Health Quality Collaborative.

An in vivo three-dimensional kinematics study of the cervical vertebrae under physiological loads in patients with cervical spondylosis.

Background Context: Studies of in vivo kinematic differences between healthy individuals and those with cervical spondylosis (CS) have been reported, but only movements under nonphysiological loads have been investigated. Differences in the in vivo, cervical kinematics between healthy individuals and those with CS are unknown.

Purpose: To investigate the in vivo, cervical kinematics of patients with CS under physiological loads.

Percutaneous and endoscopic transpapillary cholecystoduodenal stenting in acute cholecystitis-A viable long-term option in high-risk patients?

Background: The prolonged use of percutaneous cholecystostomy tubes (PCTs) in patients with acute cholecystitis, deemed inoperable, is fraught with complications. Transpapillary cholecystoduodenal stenting (TCDS) is an alternative technique that restores the physiologic outflow of bile, avoiding the need for an external drain. However, the long-term safety and efficacy of this approach remain unclear.

Inpatient cost comparison of total and unicompartmental knee arthroplasty in patients with medial compartmental osteoarthritis using time-driven activity-based costing.

Purpose: Using time-driven activity-based costing (TDABC), we sought to compare the total facility costs, comprising supply and personnel costs during the episode of care for the index procedure, in patients with isolated medial compartmental knee osteoarthritis (OA) undergoing unicompartmental knee arthroplasty (UKA) versus total knee arthroplasty (TKA).

Methods: We conducted a retrospective analysis of 100 UKAs and 100 TKAs from 2019 to 2022. From a larger sample of 4899 TKAs and 137 UKAs, patients with isolated medial OA (Kellgren-Lawrence Grade <2 in other compartments) were radiographically identified.

Patients with multiple sclerosis have higher rates of worsening following total hip arthroplasty: a propensity-matched analysis.

Introduction: The progressive nature of multiple sclerosis (MS) may adversely affect outcomes following total hip arthroplasty (THA). As patient-reported outcome measures (PROMs) in this specific group are not well defined, this study aimed to compare the clinical outcomes and the rates of achieving the minimal clinically important difference for improvement (MCID-I) and worsening (MCID-W) between patients with MS and those without MS undergoing THA.

Methods: We conducted a retrospective analysis of 375 THAs, including 75 MS patients and 300 propensity-matched non-MS patients (4:1), performed between 2016 and 2022.

Congruent Weber-B ankle fractures do not alter tibiotalar contact mechanics.

Current treatment strategy for managing Weber B ankle fractures is mainly governed by mortise congruency, malleolar alignment, deltoid ligament competence and fracture stability. While nonoperative treatment has yielded good functional outcomes in satisfactorily aligned stable injuries, a biomechanical rationale is not firmly established. Furthermore, current radiographic analysis is obscured by observer inaccuracy and beam rotation.

Primary Total Hip Arthroplasty Achieves Minimal Clinically Important Difference Faster than Revision Total Hip Arthroplasty.

Background: Despite the prevalence of total hip arthroplasty (THA) as a treatment for hip-related conditions, there is limited research directly comparing the patient-reported outcome measures between primary and revision total hip arthroplasty (rTHA). This study compared the time to achieve minimal clinically important difference (MCID) between primary and rTHA.

Methods: We conducted a retrospective analysis comparing 6,671 THAs (6,070 primary and 601 all-cause rTHAs) performed between 2016 and 2022.

A 6-Week-Old Boy With Irritability and Abdominal Distension.

A 6-week-old boy is brought to the hospital for fussiness and abdominal distension. He was febrile on presentation and was admitted to the hospital for further evaluation. On subsequent examinations, he continued to demonstrate abdominal distension and tenderness to palpation.

An International, Expert-Based Delphi Consensus Document on Controversial Issues about TransCarotid Artery Revascularization (TCAR).

Background: Transcarotid artery revascularization (TCAR) has emerged as an alternative therapeutic modality to carotid endarterectomy (CEA) and transfemoral carotid artery stenting (TFCAS) for the management of patients with carotid artery stenosis. However, certain issues regarding the indications and contraindications of TCAR remain unanswered or unresolved. The aim of this international, expert-based Delphi consensus document was to attempt to provide some guidance on these topics.

Comparing Rates of Minimal Clinically Important Difference Between Manual and Robotic-Assisted Total Knee Arthroplasty.

Background: Differences in patient-reported outcome measures (PROMs) between manual total knee arthroplasty (mTKA) and robotic-assisted TKA (rTKA) have not been adequately assessed. We compared the minimal clinically important difference (MCID) for improvement (MCID-I) and worsening (MCID-W) between mTKA and rTKA patients.

Methods: Patients who underwent primary TKA (874 mTKA and 439 rTKA) with complete preoperative and 1-year postoperative PROMs were retrospectively identified using a multihospital joint arthroplasty registry.

Revision Total Knee Arthroplasty Achieves Minimal Clinically Important Difference Faster Than Primary Total Knee Arthroplasty.

Background: Revision total knee arthroplasty (rTKA) remains underexplored regarding patient-reported outcome measures (PROMs), particularly in terms of time to reach minimal clinically important difference (MCID). This study addresses this gap by comparing the time to achieve MCID between primary TKA (pTKA) and rTKA patients, providing valuable insights into their recovery trajectories.

Methods: A total of 8,266 TKAs (7,618 pTKA and 648 rTKA) were retrospectively studied in a multi-institutional arthroplasty registry.

Multi-institutional quality improvement algorithm for home nasogastric tube care for neonates.

Background: High-risk neonates continuing to need enteral nutrition, but otherwise medically ready for discharge home from the NICU, are often offered ongoing hospitalization for nasogastric tube (NGT) feeding, versus discharge after placement of gastrostomy tube. Our group developed an interdisciplinary algorithm to support a third option-discharge home with enteral nutrition via NGT. Our objective was to develop a cross-institutional and interdisciplinary pathway to optimize outcomes for neonates discharged with NGTs.
