[Implementation of geriatric oncology in a remote hospital in French Guiana].

Introduction: The aim was to analyze the implementation of the Onco-Geriatrics model in a remote ultramarine territory: West-French Guiana. The population is socially precarious in terms of income, social coverage and administrative status, and most often speaks a non-French language and has a non-Western culture.

Methods: Narrative description of the implementation and retrospective study of anonymized data from the database of older patients managed for cancer between September 2014 and December 2020.

Human colonic organoids for understanding early events of familial adenomatous polyposis pathogenesis.

Patients with familial adenomatous polyposis (FAP) harbor mutations in the APC gene and will develop adenoma and early colorectal cancer. There is no validated treatment, and animal models are not sufficient to study FAP. Our aim was to investigate the early events associated with FAP using the intestinal organoid model in a single-center study using biopsies from nonadenomatous and adenomatous colonic mucosa of FAP patients and from healthy controls (HCs).

What Underlies State Government Performance in Scaling Family Planning Programming? A Study of The Challenge Initiative State Partnerships in Nigeria.

Introduction: Relatively few studies rigorously examine the factors associated with health systems strengthening and scaling of interventions at subnational government levels. We aim to examine how The Challenge Initiative (TCI) coaches subnational (state government) actors to scale proven family planning and adolescent and youth sexual and reproductive health approaches rapidly and sustainably through public health systems to respond to unmet need among the urban poor.

Methods: This mixed-methods comparative case study draws on 32 semistructured interviews with subnational government leaders and managers, nongovernmental organization leaders, and TCI Nigeria staff, triangulated with project records and government health management information system (HMIS) data.

The biophysical and compositional properties of human basement membranes.

Basement membranes are among the most widespread, non-cellular functional materials in metazoan organisms. Despite this ubiquity, the links between their compositional and biophysical properties are often difficult to establish due to their thin and delicate nature. In this article, we examine these features on a molecular level by combining results from proteomics, elastic, and nanomechanical analyses across a selection of human basement membranes.

Spontaneous resolution of post-hemorrhagic ventricular dilatation in preterm newborns and neurodevelopment.

Background: We investigated the temporal evolution of post-hemorrhagic ventricular dilatation (PHVD) and compared neurodevelopmental impairments (NDI) in newborns with (Group 1) spontaneous resolution of PHVD, (Group 2) persistent PHVD without neurosurgical intervention, and (Group 3) progressive PHVD receiving neurosurgical intervention.

Methods: A multicenter retrospective cohort study of newborns born at ≤34 weeks with PHVD (ventricular index [VI] >97th centile for gestational age and anterior horn width [AHW] >6 mm) from 2012 to 2020. Severe NDI was defined as global developmental delay or cerebral palsy GMFCS III-V at 18 months.
