Induction triplet chemotherapy in patients with rectal adenocarcinoma and synchronous metastases, an AGEO-FFCD study.

Aim Of The Study: The management of synchronous metastatic rectal cancer (SMRC) is complex and multimodal, involving chemotherapy, surgery and/or radiotherapy. The aim of this study was firstly to confirm the efficacy of the induction FOLFIRINOX, and secondly to evaluate the different therapeutic strategies and outcomes of patients.

Patients And Methods: This French study combined data from a prospective FFCD trial and a multicenter cohort.

Clinical, Dosimetric and Radiomic Features Predictive of Lung Toxicity After (Chemo)Radiotherapy.

Background: Treatment of locally advanced non small cell lung cancer (LA-NSCLC) is based on (chemo)radiotherapy, which may cause acute lung toxicity: radiation pneumonitis (RP). Its frequency seems to increase by the use of adjuvant durvalumab therapy.

Aims: To identify clinical, dosimetric, and radiomic factors associated with grade (G)≥2 RP and build a prediction model based on selected parameters.

Respiratory-rate Oxygenation index for Predicting Noninvasive Ventilation Associated With High-flow Nasal Cannula Failure in Acute Respiratory Failure Due to SARS-CoV-2.

Purpose: The respiratory rate-oxygenation (ROX) index is used to predict high-flow nasal cannula (HFNC) success in acute respiratory failure, including in Coronavirus disease 2019 (COVID-19) patients. However, no study has described its performance to predict failure of alternating sessions of noninvasive ventilation (NIV) and HFNC in severe COVID-19 patients.

Material And Methods: We conducted a monocentric retrospective cohort study.

Convalescent plasma in patients receiving rituximab or ocrelizumab for multiple sclerosis or neuromyelitis Optica spectrum disorder with Covid-19: A multicenter retrospective study.

Background: Despite vaccination, patients receiving anti-CD20 monoclonal antibodies (mAbs) for multiple sclerosis (MS) or neuromyelitis optica spectrum disorders (NMOSD) have an increased risk of developing severe or protracted COVID-19. The aim of this study was to describe the effect of COVID-19 convalescent plasma (CCP) in patients with MS or NMOSD exposed to anti-CD20 and infected by SARS-CoV-2.

Methods: This French national, retrospective cohort study was conducted between November 2020 and June 2023.

Foetal achondroplasia: Prenatal diagnosis, outcome and perspectives.

Background: Achondroplasia, due to a specific pathogenic variant in FGFR3, is the most common viable skeletal dysplasia and the diagnosis is mostly done in the prenatal period. Since 2021, the use of Vosoritide, a specific treatment for achondroplasia, validated in phase 3 placebo-controlled trials, has been recommended to significantly increase the height of children and infants. In the light of these new therapeutic prospects, a complete understanding of the pathophysiology of skeletal damages occurring from foetal life is required.

Endoscopic papillectomy versus surgical ampullectomy for adenomas and early cancers of the papilla: a retrospective Pancreas2000/European Pancreatic Club analysis.

Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA.

Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and more), patients with hereditary syndromes and those undergoing pancreatoduodenectomy were excluded.

Clinical value of novel blood-based tau biomarkers in Creutzfeldt-Jakob disease.

Background: The diagnostic and prognostic performance of the novel fluid biomarkers brain-derived tau (BD-tau) and phospho-tau217 (p-tau217) in Creutzfeldt-Jakob disease (CJD) is not defined.

Methods: We measured cerebrospinal fluid (CSF) and plasma BD-tau, p-tau217, p-tau181, total tau (t-tau), neurofilament light (NfL), and 14-3-3 in 100 CJD patients, 100 with non-prion rapidly progressive dementia (np-RPD), 92 with mild cognitive impairment due to Alzheimer's disease (AD-MCI), and 55 healthy controls (HC).

Results: Plasma BD-tau performed comparably to plasma t-tau but had lower performance than CSF t-tau (p < 0.

Plasma brain-derived tau correlates with cerebral infarct volume.

Background: A blood-based biomarker that accurately reflects neuronal injury in acute ischemic stroke could be an easily accessible and cost-effective complement to clinical and radiological evaluation. Here, we investigate whether plasma levels of the novel biomarker brain-derived tau (BD-tau) reflect cerebral infarct volumes and whether BD-tau can improve clinical outcome prediction.

Methods: The present study included 713 consecutive cases from two different hospital-based cohorts, the Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS) and SAHLSIS phase 2 (SAHLSIS2).

Rewiring of the glymphatic landscape in metabolic disorders.

The incorporation of the glymphatic clearance system in the study of brain physiology aids in the advancement of innovative diagnostic and treatment strategies for neurological disorders. Exploring the glymphatic system across (from) neurological and (to) metabolic diseases may provide a better link between obesity and neurological disorders. Recent studies indicate the role of metabolic dysfunction as a risk factor for cognitive decline and neurological disorders through the disruption of the glymphatic system.

Plasma phosphorylated tau (p-tau231) and total tau (t-tau) as prognostic markers of neurological outcome after cardiac arrest - a multicentre study.

Purpose: We studied the promising Alzheimer biomarker plasma tau phosphorylated at threonine 231 (p-tau231) in a cohort of cardiac arrest patients who survived to intensive care to predict long-term neurological outcomes. We also compared it to total tau (t-tau), which has demonstrated predictive abilities of neurological outcome post-cardiac arrest.

Methods: This observational multicentre cohort study included 425 patients admitted to intensive care after cardiac arrest.

Long-Term Cerebellar Consequences of Post-traumatic Brain Injury Assessed by MRI With Diffusion Tensor Imaging.

Background And Objectives: Post-traumatic brain injury (TBI) lesions, which combine brain atrophy and white matter injuries, can lead to progressive post-traumatic encephalopathy. However, the specific involvement of the cerebellum, which participates in cognitive, executive, and sensory functions, has been little studied. The aim of this work was to explore the long-term cerebellar consequences of severe TBI.

The detection of GRN mutation carriers by progranulin blood protein levels from finger-stick collection.

Introduction: Heterozygous mutations in the progranulin gene (GRN) leading to decreased progranulin levels are one of the most frequent causes of inherited frontotemporal dementia (FTD). We evaluated progranulin levels in dried blood spots from capillary finger-stick collection (DBS).

Methods: Paired venous Ethylenediaminetetraacetic acid (EDTA) plasma and DBS samples were collected from each participant with or without pathogenic GRN mutations.
