Background: The phase 2 randomised Young-PEARL study demonstrated that palbociclib plus exemestane with ovarian function suppression significantly prolonged progression-free survival compared with capecitabine in premenopausal women with hormone receptor-positive, HER2-negative metastatic breast cancer. Here, we report results of the protocol-specified secondary endpoint of overall survival.
Methods: Young-PEARL was a multicentre, randomised, open-label, phase 2 study conducted at 14 institutions in South Korea.
Purpose: To determine if iatrogenic posterior translation (UIV SPi) at the upper instrumented vertebrae (UIV) is associated with increased mechanical complications and secondarily to generate and validate a UIV SPi threshold for increased complications.
Methods: Two patient databases were utilized: one for generating a UIV SPi threshold and another for validation. Patients with a UIV between T8-L1 and a LIV at ilium were included.
Background: The microbiome has been identified as a contributor to bone quality. As skeletal health is critical to success of orthopedic surgery, the gut microbiome may be a modifiable factor associated with postoperative outcomes. For spine fusion surgery in particular, bone formation and sufficient bone mineral density are essential for successful outcomes.

The purpose of this study was to determine effects of changes in in-hospital quarantine policies on quality of care for acute stroke patients.
Methods: Hyperacute ischemic stroke patients who were admitted to Korea University Guro Hospital between January 2019 and February 2021 via the emergency department were included in this study.
Background: Coronary angiography (CAG) and targeted temperature management (TTM) may improve clinical outcomes after out-of-hospital cardiac arrest. This study aimed to assess whether the intervention effects differed according to timing and percutaneous coronary intervention (PCI) performance.
Methods And Results: Adult patients with presumed cardiac cause who underwent CAG and TTM within 24 hours following out-of-hospital cardiac arrest were included from the Korean nationwide out-of-hospital cardiac arrest registry.
Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

Few studies have distinguished the reoperation and recovery abilities of patients with PJK or PJF when fused to the upper (UT) versus lower (LT) thoracic spine. Adult spine deformity patients ≥ 18 yrs with preoperative and 5-year (5Y) data fused to the sacrum/pelvis were included.

Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

Although improvements have been realized in ASD surgery over the past decade, it is unknown whether these carry over to high-risk patients. We aim to determine temporal differences in outcomes at 2 years after ASD surgery in patients stratified by BL risk.

Methods: Adult spinal deformity (ASD) patients with baseline and perioperative (by 6 weeks) data were stratified based on single-stage (same-day) or multistage (staged) surgery, excluding planned multiple hospitalizations. Means comparison analyses were used to assess baseline demographic, radiographic, and surgical differences between cohorts.
Objective: The goal of this study was to assess the impact of fractional curve (FC) severity on curve progression and postoperative outcomes in patients undergoing adult idiopathic scoliosis (AdIS) correction.
Methods: Patients with AdIS who had preoperative coronal plane deformity and who had undergone thoracolumbar fusion with a lowermost instrumented vertebra (LIV) between L1 and L4 were included. Patients were stratified by 6-week postoperative FC severity (small FC, ≤ 40th percentile, large FC, ≥ 60th percentile of the entire cohort; calculated as the Cobb angle between LIV and S1) and age groups.
Study Design: Retrospective analysis of prospectively collected data.
Objective: This study evaluates the impact of knee osteoarthritis (OA) and knee arthroplasty on alignments and patient-reported outcomes measures (PROMS) of patients undergoing adult spinal deformity (ASD) corrective surgery.
Background: The relationship between knee OA and spinal alignment in patients with ASD is incompletely understood.
Purpose: To investigate the impact of the Global Alignment and Proportion (GAP) score components on patient outcomes in Adult Spine Deformity (ASD) surgery.
Methods: Patients included underwent assessment via the GAP score and its individual components: pelvic version (GAP PV), lumbar lordosis (GAP LL), lumbar distribution index (GAP LDI) and spinopelvic component (GAP SP). Multivariable analyses assessed the association between alignment in these components and clinical outcomes in ASD patients.
The purpose of this systematic review and meta-analysis is to assess existing literature and determine the association between the Hounsfield unit (HU) value and the vertebral body quality (VBQ) score with mechanical complications (MCs) after adult spinal deformity (ASD) surgery. Although bone quality is considered an increasingly important factor for MCs after ASD surgery, the utility of the HU value assessed by computed tomography and the VBQ score assessed by magnetic resonance imaging remains unknown. A systematic review of PubMed, Embase, and Cochrane Library databases was performed to find studies evaluating the association between the HU value and the VBQ score with MCs after ASD surgery.

Although the most widely used primary care behavioral health screener, the (), is validated for use with children without DD/D, it is unclear whether this measure accurately identifies behavioral health symptoms in youth with DD/D. Thus, the purpose of this study was to assess the psychometric properties of the for children with DD/D.
