Neuroblastoma plasticity during metastatic progression stems from the dynamics of an early sympathetic transcriptomic trajectory.

Despite their indisputable importance in neuroblastoma (NB) pathology, knowledge of the bases of NB plasticity and heterogeneity remains incomplete. They may be rooted in developmental trajectories of their lineage of origin, the sympatho-adrenal neural crest. We find that implanting human NB cells in the neural crest of the avian embryo allows recapitulating the metastatic sequence until bone marrow involvement.

Assessing the real-world effectiveness of 8 major metastatic breast cancer drugs using target trial emulation.

Background: Demonstration of trial emulation ability to benchmark randomised controlled trials (RCTs) from real-world data (RWD) is required to increase confidence in the use of routinely collected data for decision making in oncology.

Methods: To assess the frequency with which emulation findings align with RCTs regarding effect size on overall survival (OS) in metastatic breast cancer (MBC), 8 of 13 pre-selected pivotal RCTs in MBC were emulated using data from 32,598 patients enrolled in the French ESME-MBC cohort between January 1, 2008 and December 31, 2021. Adjustment methods and confounders were selected a priori for each emulation; stabilized weight was the reference method to mitigate confounding.

Intraoperative patellar tracking assessment during image-based robotic-assisted total knee arthroplasty: technical note and reliability study.

Introduction: Restoration of the anterior knee compartment is increasingly studied with the development of personalized surgery. However, evaluating the patellar tracking during the surgery is still subjective and at the surgeon's discretion. This study aimed 1) to describe the assessment of the patellar tracking during robotic-assisted total knee arthroplasty (TKA), 2) to describe a new measurement technique for evaluating the evolution of this patellar tracking, and 3) to assess its reliability and repeatability.

Bias related to overweight and obesity among French psychiatrists: Results of a national survey.

Background: According to people with a higher weight, physicians are the second most stigmatizing group related to excess weight. As a result of these weight-related biases, the therapeutic relationship with the patient and the quality of care would be negatively affected. In addition, this stigma could negatively impact the clinical practice related to higher weight and avoidance of care.

Patellar morphology is different in patellofemoral instability: An MRI comparative case-control study.

Purpose: Although patellofemoral instability (PFI) affects both femoral and patellar compartments, literature provided little attention for the patellar morphology contribution on PFI. This study evaluates the patellar morphology patterns on MRI to establish their contribution in PFI.

Methods: This study retrospectively analyzes patellar MRI and X-ray measurements performed between 2018 and 2022.

Real-world data for marginal zone lymphoma patients in the French REALYSA cohort: The REALMA study.

Marginal Zone Lymphoma (MZL) comprises three subtypes: extranodal MZL (EMZL), splenic MZL (SMZL) and nodal MZL (NMZL). Since clinical trials have limited representativeness, there is a need for real-world data (RWD) evidence in MZL. Real-world data in Lymphoma and survival in Adults (REALYSA) is a prospective multicentric French cohort of newly diagnosed lymphoma patients.

Identifying psychosocial and contextual markers considered by physicians to personalize care.

Background: The objective of the study was to identify the psychosocial and contextual markers considered by physicians to personalize care.

Methods: An online questionnaire with one open-ended question, asking physicians to describe clinical situations in which they personalized care, was used. Physicians were recruited from March 31, 2023, to August 10, 2023, from three hospitals, five university departments of general practice and six physician organizations in France.

DNA methylation as a new tool for the differential diagnosis between T-LBL and lymphocyte-rich thymoma.

T-lymphoblastic lymphoma (T-LBL) and thymoma are two rare primary tumors of the thymus deriving either from T-cell precursors or from thymic epithelial cells, respectively. Some thymoma subtypes (AB, B1, and B2) display numerous reactive terminal deoxynucleotidyl transferase-positive (TdT) T-cell precursors masking epithelial tumor cells. Therefore, the differential diagnosis between T-LBL and TdT T-lymphocyte-rich thymoma could be challenging, especially in the case of needle biopsy.

Is outpatient joint arthroplasty safe in a high volume academic centre? A retrospective monocentric study using an institutional pathway.

Purpose: Hip and knee arthroplasties are daily procedures in orthopaedic departments. Recently, same-day discharge (SDD) became increasingly popular, but doubts remain about its safety and generalization. Our hypothesis is that outpatient arthroplasty, in a high volume centre and with an institutional protocol, is an effective and reliable practice.

Stress shielding in stemmed reverse shoulder arthroplasty: an updated review.

Background: Reverse shoulder arthroplasty (RSA) is popular for the treatment of degenerative glenohumeral joint disease. Bone remodeling around the humeral stem related to stress shielding (SS) has been described. This review focuses on the specific radiological characteristics, risk factors, and clinical consequences of SS in RSA.

Phase IB part of LOC-R01, a LOC network non-comparative randomized phase IB/II study testing R-MPV in combination with escalating doses of lenalidomide or ibrutinib for newly diagnosed primary central nervous system lymphoma (PCNSL) patients.

Background: Results of conventional induction chemotherapies in primary central nervous system lymphoma (PCNSL) need to be improved. Ibrutinib, a BTK inhibitor, and lenalidomide, an immunomodulatory drug, have shown promising results at relapse, supporting to further assess their individual use in combination with high-dose methotrexate-based chemotherapy.

Methods: Patients with newly diagnosed PCNSL were randomized to receive four 28-day cycles of ibrutinib or lenalidomide in combination with R-MPV (rituximab, methotrexate, procarbazine, vincristine and prednisone) in a 3 + 3 design.

Is bicortical femoral pin insertion safe for Image-based Robotic Knee Arthroplasty Surgery ? A comparative complications analysis in 970 Consecutive Cases.

Objectives: Limited data exists on complications associated with robotic image-based system in knee arthroplasty. This study aims to document complications in robotic arm-assisted knee arthroplasties, and evaluate the system's safety by comparing two femoral pin insertion methods: bicortical diaphyseal with additional stab wounds, and unicortical metaphyseal placement through the main incision.

Methods: All patients undergoing primary knee arthroplasty with the image-based robotic system (Mako, Stryker, Mako Surgical Corp.

Virtual surgical planning in orthognathic surgery: A prospective evaluation of postoperative accuracy.

Objectives: The development of 3D computer-assisted technologies over the past years has led to vast improvements in orthognathic surgery. The aim of the present study was to evaluate differences in maxillary position between 3D virtual surgical planning (VSP) and surgical results.

Materials And Methods: We assessed data from 25 patients who underwent bimaxillary non-segmented orthognathic surgery with 3D VSP.

Long-term enophthalmos after complex orbital bone loss successfully treated with patient-specific porous titanium implants: A case series.

Introduction: Long-term enophthalmos and diplopia resulting from orbital bone loss pose significant challenges in reconstructive surgery. This study evaluated the effectiveness of patient-specific porous titanium implants (PSIs) for addressing these conditions.

Materials And Methods: This retrospective study involved 12 patients treated at Croix-Rousse Hospital, Lyon, from April 2015 to April 2022 who underwent late reconstruction via PSI for unilateral complex orbital bone loss.

Similar complications and outcomes with simultaneous versus staged bilateral total hip arthroplasty with the direct anterior approach: A comparative study.

Introduction: Simultaneous bilateral total hip arthroplasty (THA) has demonstrated similar clinical outcomes to staged bilateral THA. However, there is scarce data regarding the early postoperative complications. This study compares simultaneous to staged bilateral THA with the direct anterior approach (DAA) regarding early complications and revision surgeries.
