G-POEM in Belgium : a retrospective study.

Gastroparesis is a condition with a growing incidence and few effective treatments. In recent years, GPOEM has demonstrated its superiority to other existing treatments. We report here on our experience in which 34 patients underwent GPOEM, with 23 patients assessed for symptoms and quality of life before and after the procedure.

Peroral endoscopic myotomy: a two-center retrospective study of practice and adverse events.

Background And Study Aims: Peroral endoscopic myotomy (POEM) is the preferred technique for the treatment of esophageal motility disorders and is less invasive than surgery. This study was performed to compare two university centers in the practice of POEM, in terms of efficacy and adverse events, for the treatment of esophageal motility disorder.

Patients And Methods: Retrospective comparative study of patients undergoing a POEM between September 2020 and December 2022 from the University Hospital of Liège (Belgium) and Besançon (France).

Clarifying the effect of biodiversity on productivity in natural ecosystems with longitudinal data and methods for causal inference.

Causal effects of biodiversity on ecosystem functions can be estimated using experimental or observational designs - designs that pose a tradeoff between drawing credible causal inferences from correlations and drawing generalizable inferences. Here, we develop a design that reduces this tradeoff and revisits the question of how plant species diversity affects productivity. Our design leverages longitudinal data from 43 grasslands in 11 countries and approaches borrowed from fields outside of ecology to draw causal inferences from observational data.

[Hemophagocytic lymphohistiocytosis on Epstein-Barr Virus reactivation].

We describe the case of a 43-years-old female patient admitted in the emergency department for impairment of general condition and dyspnea. This patient is on immunosuppressive medication for Behçet's disease and will develop a lymphoma and hemophagocytic lymphohistiocytosis following Epstein-Barr virus (EBV) reactivation. This clinical case introduces a brief literature review about hemophagocytic lymphohistiocytosis (HLH).
