Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...

Statistical mechanics: autonomous to autonomous via non autonomous

open access: yes, 2023
Abstract We are to formulate the invariant measures to fix compact subsets on the fluctuated situations for two autonomous systems in transition. Such a kind of two autonomous systems is formulated and intermediated by a certain formalism of their relevant non autonomous system that cannot be revealed other than by etale cohomology, l-adic ...
