Toxoplasma gondii from Gabonese forest, Central Africa: First report of an African wild strain.

The protozoan Toxoplasma gondii is a ubiquitous and highly prevalent parasite that can theoretically infect all warm-blooded vertebrates. In humans, toxoplasmosis causes infections in both immunodeficient and immunocompetent patients, congenital toxoplasmosis, and ocular lesions. These manifestations have different degrees of severity.

Prognostic value of circulating tumor DNA at diagnosis and its early decrease after one cycle of neoadjuvant chemotherapy for patients with advanced epithelial ovarian cancer. An ancillary analysis of the CHIVA phase II GINECO trial.

Objective: To evaluate the prognostic impact of circulating tumor DNA (ctDNA) detection at diagnosis (T0) and its early decrease after one cycle (T1) of neoadjuvant chemotherapy (NACT) in patients with advanced epithelial ovarian cancer (EOC) included in the CHIVA trial (NCT01583322).

Methods: Blood samples were collected at T0 and before each administration of NACT. Circulating tumor DNA detection was performed by next-generation sequencing.

Laboratory practices for the diagnosis and management of mucormycosis in France, 2024.

This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

The CD47/TSP-1 axis: a promising avenue for ovarian cancer treatment and biomarker research.

Background: Ovarian cancer (OC) remains one of the most challenging and deadly malignancies facing women today. While PARP inhibitors (PARPis) have transformed the treatment landscape for women with advanced OC, many patients will relapse and the PARPi-resistant setting is an area of unmet medical need. Traditional immunotherapies targeting PD-1/PD-L1 have failed to show any benefit in OC.

Neoadjuvant and adjuvant pembrolizumab in advanced high-grade serous carcinoma: the randomized phase II NeoPembrOV clinical trial.

This open-label, non-comparative, 2:1 randomized, phase II trial (NCT03275506) in women with stage IIIC/IV high-grade serous carcinoma (HGSC) for whom upfront complete resection was unachievable assessed whether adding pembrolizumab (200 mg every 3 weeks) to standard-of-care carboplatin plus paclitaxel yielded a complete resection rate (CRR) of at least 50%. Postoperatively patients continued assigned treatment for a maximum of 2 years. Postoperative bevacizumab was optional.

Effect of the 1-h bundle on mortality in patients with suspected sepsis in the emergency department: a stepped wedge cluster randomized clinical trial.

Purpose: The efficacy of the 1-h bundle for emergency department (ED) patients with suspected sepsis, which includes lactate measurement, blood culture, broad-spectrum antibiotics administration, administration of 30 mL/kg crystalloid fluid for hypotension or lactate ≥ 4 mmol/L, remains controversial.

Methods: We carried out a pragmatic stepped-wedge cluster-randomized trial in 23 EDs in France and Spain. Adult patients with Sepsis-3 criteria or a quick sequential organ failure assessment (SOFA) score ≥ 2 or a lactate > 2 mmol/L were eligible.

Bortezomib, thalidomide, and dexamethasone with or without daratumumab and followed by daratumumab maintenance or observation in transplant-eligible newly diagnosed multiple myeloma: long-term follow-up of the CASSIOPEIA randomised controlled phase 3 trial.

Background: CASSIOPEIA part 1 demonstrated superior depth of response and prolonged progression-free survival with daratumumab in combination with bortezomib, thalidomide, and dexamethasone (D-VTd) versus bortezomib, thalidomide, and dexamethasone (VTd) alone as an induction and consolidation regimen in transplant-eligible patients newly diagnosed with myeloma. In CASSIOPEIA part 2, daratumumab maintenance significantly improved progression-free survival and increased minimal residual disease (MRD)-negativity rates versus observation. Here, we report long-term study outcomes of CASSIOPEIA.

Curative criteria for endoscopic treatment of colorectal cancer.

As endoscopic treatment enables en bloc resection of T1 colorectal cancers, the risk of recurrence, often assimilated to the risk of lymph node metastases, must be assessed in order to offer patients an additional treatment if this risk is deemed significant. The curative criteria currently used by most guidelines are depth of invasion <1 mm, well or moderately differentiated tumour, absence of lympho-vascular invasion, absence of significant budding and tumour-free resection margins. However, these factors must be assessed by qualified pathologists, as they are difficult to evaluate.

Will Endoscopic-Ultrasound-Guided Choledocoduodenostomy with Electrocautery-Enhanced Lumen-Apposing Metal Stent Placement Replace Endoscopic Retrograde Cholangiopancreatography When Treating Distal Malignant Biliary Obstructions?

Malignant distal biliary obstructions are becoming increasingly common, especially in patients with cancers of the pancreatic head, despite progress in medical oncology research. ERCP is the current gold standard for management of such strictures, but the emergence of EC-LAMS has rendered EUS-CDS both safe and efficient. It is a "game changer"; originally intended for ERCP failure, two randomised clinical trials recently proposed EUS-CDS as a first-intent procedure in palliative settings.

Infections Differ Among Human Immunodeficiency Virus (HIV)-Seropositive and HIV-Seronegative Individuals: Results From a Nationwide Surveillance Program in France.

Among 1107 cryptococcosis cases from the French surveillance network (2005-2020), the proportion of HIV-seronegative individuals has recently surpassed that of HIV-seropositive individuals. We observed marked differences in patient characteristics, disease presentations, cryptococcal antigen results, infecting species, and mortality according to HIV serostatus.

Short course radiotherapy versus radiochemotherapy for locally advanced rectal cancers in the elderly (UNICANCER PRODIGE 42/GERICO 12 study): Quality of life and comprehensive geriatric assessment.

Background: The results of the PRODIGE 42/GERICO 12 study showed that short course radiotherapy had a better tolerance profile than radiochemotherapy, with comparable oncological results. We have included Quality of Life analyses and oncogeriatric evaluations in this study.

Patients And Methods: In all, 101 patients ≥75 years of age with resectable T3-T4 rectal adenocarcinoma less than 12 cm from the anal margin received short course radiotherapy (5X5 Gy in one week) or radiochemotherapy (50 Gy, 2 y/f and capecitabine 800 mg/m, 5 days/week) with delayed surgery (7 weeks ± 1) in both groups.

Beyond MEN1, When to Think About MEN4? Retrospective Study on 5600 Patients in the French Population and Literature Review.

Context: Germline CDKN1B variants predispose patients to multiple endocrine neoplasia type 4 (MEN4), a rare MEN1-like syndrome, with <100 reported cases since its discovery in 2006. Although CDKN1B mutations are frequently suggested to explain cases of genetically negative MEN1, the prevalence and phenotype of MEN4 patients is poorly known, and genetic counseling is unclear.

Objective: To evaluate the prevalence of MEN4 in MEN1-suspected patients and characterize the phenotype of MEN4 patients.

Bone marrow graft versus peripheral blood graft in haploidentical hematopoietic stem cells transplantation: a retrospective analysis in1344 patients of SFGM-TC registry.

The use of peripheral blood (PB) or bone marrow (BM) stem cells graft in haploidentical hematopoietic stem cell transplantation with post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis remains controversial. Moreover, the value of adding anti-thymoglobulin (ATG) to PTCy is unknown. A total of 1344 adult patients received an unmanipulated haploidentical transplant at 37 centers from 2012 to 2019 for hematologic malignancy.

Methods: T. gondii field isolates were collected from different parts of Europe and assessed by whole genome sequencing (WGS).

Liver disease in germline mutations of telomere-related genes: Prevalence, clinical, radiological, pathological features, outcome, and risk factors.

Background And Aim: Germline mutations of telomere-related genes (TRG) induce multiorgan dysfunction, and liver-specific manifestations have not been clearly outlined. We aimed to describe TRG mutations-associated liver diseases.

Approach And Results: Retrospective multicenter analysis of liver disease (transaminases > 30 IU/L and/or abnormal liver imaging) in patients with TRG mutations.

[Bronchoscopic COPD treatments].

Introduction: Chronic obstructive pulmonary disease (COPD) is associated with disabling respiratory symptoms including dyspnea, frequent exacerbations and chronic bronchitis. The currently available pharmacological and non-pharmacological therapies have limited efficacy, necessitating the development of interventional strategies, many of them endoscopic.

State Of The Art: Endoscopic lung volume reduction has markedly increased over recent years, principally as regards the endobronchial valves currently used in routine care.

A dual function for the chromatin organizer Special A-T rich Binding Protein 1 in B-lineage cells.

SATB1 (Special A-T rich Binding protein 1) is a cell type-specific factor that regulates the genetic network in developing T cells and neurons. In T cells, SATB1 is required for lineage commitment, VDJ recombination, development and maturation. Considering that its expression varies during B-cell differentiation, the involvement of SATB1 needs to be clarified in this lineage.
