Purpose: In the context of pediatric cancer, siblings' adaptation and needs have been previously investigated; however, research on the long-term consequences on siblings, especially on their family environment, is scarce. We aimed to (1) assess the family functioning (FF) perceived by siblings of childhood leukemia survivors long after diagnosis and (2) explore characteristics likely associated and investigate associations with psycho-behavioral and social factors.

Methods: Childhood leukemia survivors' siblings older than 11 years were recruited through the LEA cohort, a French long-term follow-up program, and completed the family assessment device (FAD).

Cancers rely on multiple, heterogeneous processes at different scales, pertaining to many biomedical fields. Therefore, understanding cancer is necessarily an interdisciplinary task that requires placing specialised experimental and clinical research into a broader conceptual, theoretical, and methodological framework. Without such a framework, oncology will collect piecemeal results, with scant dialogue between the different scientific communities studying cancer.

Parasite

April 2023

Parasitology-Mycology Laboratory, French National Reference Center for Echinococcosis, University Hospital of Besançon and Franche-Comté University, F-25030, Besançon, France - UMR 6249 CNRS-Franche-Comté University « Chrono-Environnement », F-25030, Besançon, France - Visceral Surgery/Liver Transplant Unit, French National Reference Center for Echinococcosis, University Hospital of Besançon and Franche-Comté University, F-25030, Besançon, France.

Alveolar echinococcosis (AE) is a severe parasitic infection caused by the ingestion of Echinococcus multilocularis eggs. While higher incidence and faster evolution have been reported in immunosuppressed patients, no studies have been performed specifically on AE in transplant patients. We searched for all de novo AE cases diagnosed between January 2008 and August 2018 in solid organ transplant (SOT) recipients included in the Swiss Transplant Cohort Study and the FrancEchino Registry.

Craniopharyngiomas are commonly classified as low-grade tumors, although they may harbor a malignant behavior due to their high rate of recurrence and long-term morbidity. Craniopharyngiomas are classically distinguished into two histological types (adamantinomatous and papillary), which have been recently considered by the WHO classification of CNS tumors as two independent entities, due to different epidemiological, radiological, histopathological, and genetic patterns. With regard to papillary craniopharyngioma, a BRAF V600 mutation is detected in 95% of cases.

Haematopoietic stem cell reinjection may be a curative option for poor graft function after haematopoietic stem cell transplantation; however, literature supporting its use remains limited. We conducted a multicentre retrospective study on behalf of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy, including 55 patients. We demonstrated response rates of nearly 40% and two-year survival of more than 60% in the context of an otherwise deadly complication and we observed that the timing of injection and the degree of cytopenia are strongly associated with outcomes.

Department of digestive surgery, center of bariatric surgery, university hospital of Édouard-Herriot, hospices civils de Lyon, Lyon, France; Specialized center of obesity, university hospital of Lyon, hospices civils de Lyon, Pierre-Bénite, France; University Claude Bernard Lyon 1, Lyon, France; Carmen lab, Inserm unit 1060, France.

The outcomes of bariatric surgery, while often impressive, are not universally satisfactory; they vary from patient to patient and from operation to operation. Between 20-30% of patients experience suboptimal weight loss or substantial weight regain early in their postoperative course. Confronted with this chronic disease, and given that failures are difficult to manage, it is essential to better characterize obesity preoperatively, considering other metrics beyond just the body mass index (BMI), to select the best candidates for surgery and optimize the benefit/risk ratio.

While new-onset status epilepticus (NOSE) is a harbinger of chronic epilepsy, prospective medical data are sparse in terms of specifying whether the evolution of status epilepticus (SE) and seizure expression in NOSE resembles what occurs in patients who have already been diagnosed with epilepsy [non-inaugural SE (NISE)] in all aspects apart from its inaugural nature. The aim of this study was to compare the clinical, MRI, and EEG features that could distinguish NOSE from NISE. We conducted a prospective monocentric study in which all patients ≥18 years admitted for SE over a 6-month period were included.

Aims: Recently, YAP1 fusion genes have been demonstrated in eccrine poroma and porocarcinoma, and the diagnostic use of YAP1 immunohistochemistry has been highlighted in this setting. In other organs, loss of YAP1 expression can reflect YAP1 rearrangement or transcriptional repression, notably through RB1 inactivation. In this context, our objective was to re-evaluate the performance of YAP1 immunohistochemistry for the diagnosis of poroma and porocarcinoma.
