[Update on acute leukemia of ambiguous lineage in 2023 - Recommendations of the French Society for Childhood and Adolescent Cancer and Leukemia (SFCE)].

Acute leukemias of ambiguous lineage (ALAL) represent between 3 and 5% of childhood AL. This term encompasses many subtypes of AL that have been defined according to the immunophenotypic profile based on the expression of various lineage markers. This classification has been modified and enriched during the last decade thanks to the improvement of molecular biology techniques, which have led to reconsider the ontogenic proximity existing between certain forms of ALAL.

Elderly patients with venous thromboembolism: Insights from the RIETE registry.

Venous thromboembolism (VTE) presents a notable healthcare burden, particularly among the elderly, who experience increased risks and more severe complications. This review aims to use the extensive data from the RIETE registry, a comprehensive database on consecutive patients with VTE. We examine the clinical features, therapeutic approaches, and patient outcomes of VTE in elderly patients, compared to younger patients, offering a comprehensive understanding of management challenges and emphasizing the need for strategies that accommodate the unique challenges of this population.

Impact of horticultural therapy on patients admitted to psychiatric wards, a randomised, controlled and open trial.

Psychiatric inpatients often endure anxiety. This randomized trial assessed the impact of horticultural therapy on anxiety in adult psychiatric inpatients over four weeks, compared to standard care. Recruiting 211 inpatients from six units were randomized into control (n = 105) and experimental (n = 106) groups.

Enoxaparin versus Placebo to Prevent Symptomatic Venous Thromboembolism in Hospitalized Older Adult Medical Patients.

BACKGROUND: Admission to the hospital is a major risk factor for the development of venous thromboembolism (VTE). Whether thromboprophylaxis with low-molecular-weight heparin prevents symptomatic VTE in medically ill, hospitalized older adults remains debated. METHODS: In a prospective, randomized, placebo-controlled, double-blind, multicenter trial, older adults (>70 years of age) hospitalized for acute medical conditions were randomly assigned to receive 40 mg a day of low-molecular-weight heparin (enoxaparin) or placebo for 6 to 14 days.

Diagnosis and treatment of cervical spine injuries in children.

Cervical spine injuries in children are a common reason for emergency room visits, while bone, ligament or spinal cord cervical lesions are relatively rare (1-1.5% of severe trauma in children) and mainly involve the upper cervical spine. The main causes are sports injuries, accidents at home and traffic accidents.

Pulmonary embolism diagnostic strategies in patients with COPD exacerbation: Post-hoc analysis of the PEP trial.

Background: The prevalence of pulmonary embolism (PE) is approximately 11-17 % in patients with an acute exacerbation of chronic obstructive pulmonary disease (AE-COPD). The optimal diagnostic strategy for PE in these patients remains undetermined.

Aims: To evaluate the safety and efficacy of standard (revised Geneva and Wells PE scores combined with fixed D-dimer cut-off) and computed tomography pulmonary angiogram (CTPA)-sparing diagnostic strategies (ADJUST-PE, YEARS, PEGeD, 4PEPS) in patients with AE-COPD.

[Unrelated donor selection for allogeneic hematopoietic stem cell transplantation: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)].

The selection of a donor is an essential element in allogeneic hematopoietic stem cell transplantation. In the absence of an HLA-matched related donor, the selection of an unrelated donor is considered, and is currently the most common type of allogenic donor used in practice. Many criteria are considered for the selection when multiple donors are available, particularly in case of partial match.

Proof-of-Concept Human Organ-on-Chip Study: First Step of Platform to Assess Neuro-Immunological Communication Involved in Inflammatory Bowel Diseases.

Inflammatory bowel diseases (IBD) are complex chronic inflammatory disorders of the gastrointestinal (GI) tract. Recent evidence suggests that the gut-brain axis may be pivotal in gastrointestinal and neurological diseases, especially IBD. Here, we present the first proof of concept for a microfluidic technology to model bilateral neuro-immunological communication.

Impact of Epithelial Histological Types, Subtypes, and Growth Patterns on Oncological Outcomes for Patients with Nonmetastatic Prostate Cancer Treated with Curative Intent: A Systematic Review.

Context: The optimal management for men with prostate cancer (PCa) with unconventional histology (UH) is unknown. The outcome for these cancers might be worse than for conventional PCa and so different approaches may be needed.

Objective: To compare oncological outcomes for conventional and UH PCa in men with localized disease treated with curative intent.

Molecular and clinicopathologic characterization of pediatric histiocytoses.

The spectrum of somatic mutations in pediatric histiocytoses and their clinical implications are not fully characterized, especially for non-Langerhans cell histiocytosis (-LCH) subtypes. A cohort of 415 children with histiocytosis from the French histiocytosis registry was reviewed and analyzed for BRAF . Most BRAF samples were analyzed by next-generation sequencing (NGS) with a custom panel of genes for histiocytosis and myeloid neoplasia.

Stent-Assisted Coiling in the Treatment of Unruptured Intracranial Aneurysms: A Randomized Clinical Trial.

Background And Purpose: Stent-assisted coiling may improve angiographic results of endovascular treatment of unruptured intracranial aneurysms compared with coiling alone, but this has never been shown in a randomized trial.

Materials And Methods: The Stenting in the Treatment of Aneurysm Trial was an investigator-led, parallel, randomized (1:1) trial conducted in 4 university hospitals. Patients with intracranial aneurysms at risk of recurrence, defined as large aneurysms (≥10 mm), postcoiling recurrent aneurysms, or small aneurysms with a wide neck (≥4 mm), were randomly allocated to stent-assisted coiling or coiling alone.

Staphylococcus lugdunensis prosthetic joint infection: A multicentric cohort study.

Objectives: To describe Staphylococcus lugdunensis prosthetic joint infection (PJI) management and outcome.

Methods: Adults with proven S. lugdunensis PJI were included in a multicentric retrospective cohort.

Frequency and predictors for chronic thromboembolic pulmonary hypertension after a first unprovoked pulmonary embolism: Results from PADIS studies.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening complication of a pulmonary embolism (PE) whose incidence and predictors are not precisely determined.

Objective: To determine the frequency and predictors for CTEPH after a first unprovoked PE.

Patients/methods: In a randomized trial comparing an additional 18-month warfarin versus placebo in patients after a first unprovoked PE initially treated with vitamin K antagonist for 6 months, we applied recommended CTEPH screening strategies through an 8-year follow-up to determine cumulative incidence of CTEPH.

Management of Biochemical Recurrence of Prostate Cancer After Curative Treatment: A Focus on Older Patients.

Following a treatment with curative intent, a biochemical recurrence may be diagnosed, often many years after the primary treatment. The consequences of this relapse on survival are very heterogeneous. The expected specific survival at relapse is above 50% at 10 years.

Automated Coding in Case Mix Databases of Bacterial Infections Based on Antimicrobial Susceptibility Test Results.

Our objective was to improve the accuracy of bacteria and resistance coding in a hospital case mix database. Data sources consisted of 50,074 files on bacteriological susceptibility tests transmitted with the HPRIM protocol from laboratory management system to electronic health record of the University hospital of Saint Etienne in July 2017. An algorithm was implemented to detect susceptibility tests containing information corresponding to codes whose addition in the case mix database was susceptible to increase the severity level of a diagnosis related group.

Survival and complications of total hip arthroplasty using third-generation dual-mobility cups with non-cross-linked polyethylene liners in patients younger than 55years.

Background: In younger patients, total hip prostheses are subjected to wide motion ranges and wear-inducing forces. Dual-mobility cups (DMCs) are effective in decreasing the risk of dislocation. However, wear and osteolysis have been reported with first-generation DMCs.

[Geriatric assessment and treatment of nonmetastatic muscle-invasive bladder cancer in patients over 75 years of age. Retrospective and multicentric study of 121 cases].

Objective: The aim of our study was to assess prevalence of geriatric assessment (GA) in patients over 75years with nonmetastatic invasive bladder cancer (MIBC).

Material And Methods: We performed a retrospective study between 2000 and 2015. We assessed comobidity by Charlson score and ASA score, geriatric assessement (GA) and treatments.

COVID-19 vaccines: Frequently asked questions and updated answers.

At the end of December 2019, China notified the World Health Organization about a viral pneumonia epidemic soon to be named COVID-19, of which the infectious agent, SARS-CoV-2, was rapidly identified. Less than one year later, published phase 3 clinical trials underlined the effectiveness of vaccines utilizing hitherto unusual technology consisting in injection of the messenger RNA (m-RNA) of a viral protein. In the meantime, numerous clinical trials had failed to identify a maximally effective antiviral treatment, and mass vaccination came to be considered as the strategy most likely to put an end to the pandemic.

Poor outcome associated with mucormycosis in critically ill hematological patients: results of a multicenter study.

Background: Mucormycosis is an emerging fungal infection that may lead to multi-organ failure, especially in patients with hematological malignancies (HM). We performed a retrospective, cohort study, in five intensive care units (ICU) to assess the outcome of critically ill patients with HM and mucormycosis between 2002 and 2018. The secondary objective was to identify prognostic factors in this setting.
