Volumetric Wear of Highly Cross-Linked Polyethylene Sockets in Total Hip Arthroplasty Differs Among Brands: A Retrieval Study

Outcomes after total hip arthroplasty (THA) remain limited by wear and wear particle reaction. Although highly cross-linked polyethylene (HXLPE) mitigated this issue, there are major differences among the various brands available. This study quantified, for the first time, the vo...

AmpliconSuite: an end-to-end workflow for analyzing focal amplifications in cancer genomes

Abstract Here we present AmpliconSuite, a toolkit for focal amplification analysis from cancer whole-genome sequencing that identifies extrachromosomal DNA (ecDNA), breakage–fusion–bridges and other amplification modes. Its ecContext module categorizes ecDNA structures to underst...

Initial treatment strategies and outcomes across haemodynamic thresholds and risk stratification in incident systemic sclerosis–associated pulmonary arterial hypertension: a EUSTAR analysis

OBJECTIVE: Real-world initial treatment strategies in SSc-PAH remain incompletely described. We aimed to characterise these strategies across haemodynamic thresholds and risk strata and evaluate outcome associations. METHODS: We analysed treatment-naïve SSc-PAH patients in EUSTAR...

TCR sensitivity shapes recognition of tumor antigen presented by host cells and TCR-T cell efficacy in solid tumors

Despite advances in adoptive T cell therapy, therapeutic efficacy in solid tumors remains inconsistent, and the mechanistic determinants of treatment failure are incompletely understood. Increasing evidence suggests that effective antitumor responses depend not only on direct rec...

Disease Duration Differentiates Freezing of Gait Response to Subthalamic and Nigral Stimulation for Parkinson's Disease in an Exploratory Multicenter Controlled Trial

BACKGROUND: Freezing of gait (FoG) belongs to most pressing unmet symptoms in the treatment of Parkinson's disease. OBJECTIVES: To explore whether combined subthalamic and nigral (STN + SNr) deep brain stimulation improves FoG compared with optimized STN stimulation alone; to ide...

Procedural Complications and Implant Cutout of the SpineJack®-System in Thoracolumbar Vertebral Fractures: A Retrospective Analysis of 204 Implants from a Level-1 Trauma Center

Study DesignRetrospective cohort study.ObjectivesImplant-related complications of SpineJack® stent-kyphoplasty, particularly endplate cutout, remain poorly characterized. This study determined the incidence of procedural complications, with a focus on cutout, and identified assoc...

Longitudinal Functional Magnetic Resonance Imaging to Assess Lung Disease in Cystic Fibrosis

Abstract Rationale Matrix pencil decomposition magnetic resonance imaging (MP-MRI) enables quantitative assessment of lung ventilation and perfusion and was shown to correlate with contrast-enhanced (CE) perfusion MRI. Objectives To determine the longitudinal course of MP-MRI par...

Is There an Association Between Preoperative PONV Prophylaxis With Dexamethasone and Incidence of Wound Revisions in the Surgical Treatment of Pediatric Secondary Scoliosis? A Retrospective Cross-Sectional Study in 162 Patients

BACKGROUND DATA: Pediatric patients undergoing surgery for secondary scoliosis are at special risk for surgical site infections (SSIs). The application of dexamethasone (Dexa) for perioperative prophylaxis of postoperative nausea and vomiting is an established method. Despite the...

Measurement properties of instruments for post-extubation dysphagia in critically ill patients: A systematic review

OBJECTIVES: Post-extubation dysphagia (PED) is a common but often under-recognised complication in critically ill patients following invasive mechanical ventilation. Systematic assessment of PED in routine ICU practice is not common. This systematic review aimed to identify clini...

Reported practice patterns in the use of local antibiotics for fracture-related infection among SICOT respondents: an international survey

Abstract Background Local antibiotics are increasingly used in the management of fracture-related infection (FRI), but international practice patterns regarding their indications, antibiotic selection, and application methods remain heterogeneous and insufficiently standardised....

A multiregional serosurvey of RNA virus-reactive antibodies in bats and rodents reveals the enzootic presence of flavi- and paramyxoviruses in African Pteropodidae

Bats and rodents have been identified as reservoir hosts of diverse RNA viruses that pose potential risks to humans. However, overall virus prevalence in wildlife and underlying factors determining the zoonotic potential of reservoir-borne viruses remain poorly characterized. Vir...

Proteome-guided drug discovery maps and mitigates therapeutic degrader toxicity

Abstract Heterobifunctional targeted degraders (HBDs) enable potent removal of protein targets but their clinical success can be hindered by de novo toxicity inherent to their bivalent chemistry. Here we introduce a drug discovery framework that exploits high-throughput proteomic...

Workshop: Introduction to Systematic Review & Meta-Analysis of Animal Studies

Materials associated with our workshop "Introduction to Systematic Review & Meta-Analysis of Animal Studies". In this workshop you will learn the key steps required to conduct a systematic review and meta-analysis of preclinical animal studies. Until further notice, this is an on...

Prognosis of acute symptomatic seizures and impact of prolonged treatment with anti‐seizure medication

Abstract Objectives Acute symptomatic epileptic seizures (ASySs) occur in temporal proximity to acute brain insults. Given their low risk of subsequent unprovoked seizures, current guidelines recommend either no treatment with anti‐seizure medication (ASM) or early discontinuatio...

MOSAIC: Intra-tumoral heterogeneity characterization through large-scale spatial and cell-resolved multi-omics profiling

Understanding the tumor microenvironment has the potential to significantly advance precision oncology, but this effort has been hampered by the scarcity of consistent large data sets. Here, we introduce MOSAIC (Multi-Omics Spatial Atlas in Cancer), a multi-center clinical omics...

Using multi-trait polygenic scores to predict lithium responsiveness in patients with bipolar disorder

Background The predictive power of polygenic scores (PGSs) for lithium treatment response in bipolar disorder remains limited. Aims To enhance the prediction of lithium responsiveness by developing a multi-trait PGS (mt-PGS) combining genetic information from multiple phenotypes...

A global sagittal deviation index (GSDI-5) incorporating upper cervical alignment: initial construct validation in forward head posture

Abstract Purpose Forward head posture (FHP) is commonly assessed using isolated cervical measures, potentially overlooking its relationship with global sagittal alignment. This study introduces the Global Sagittal Deviation Index (GSDI-5), a composite measure integrating multireg...

Pre-ECMO characteristics, organ dysfunction and exploratory mortality prediction in COVID-19 versus non-COVID-19 ARDS treated with veno-venous ECMO: a retrospective cohort study

Abstract Objective The transferability of pre-ECMO characteristics and established mortality prediction tools across COVID-19 (C-19) and non-COVID-19 (nC-19) acute respiratory distress syndrome (ARDS) remains uncertain. We compared clinical characteristics, organ dysfunction, res...
