Article Synopsis
  • Neuroblastoma has two main cell types: therapy-sensitive adrenergic (ADRN) and therapy-resistant mesenchymal (MES).
  • Researchers used experiments and mathematical models to study how these cell types respond to treatment and whether they are distinct or dynamic states.
  • The findings suggest that ADRN and MES are distinct cell types, and their different growth and survival rates, rather than switching between states, significantly influence how the cancer responds to therapy.

Background: Glioblastoma is a highly aggressive primary central nervous system tumor characterized by poor outcomes. In case of relapse or progression to adjuvant chemotherapy, there is no univocal preferred regimen for relapsing glioblastoma.

Methods: We conducted a systematic review and Bayesian trial-level network meta-analyses (NMA) to identify the regimens associated with the best outcomes.

Background & Aims: Expression of P21, encoded by the gene, has been associated with fibrosis progression in steatotic liver disease (SLD); however, the underlying mechanisms remain unknown. In the present study, we investigated the function of CDKN1A in SLD.

Methods: expression levels were evaluated in different patient cohorts with SLD, fibrosis, and advanced chronic liver disease (ACLD).

Objectives: Antibiotic use is increasing in low- and middle-income countries (LMIC); however, few studies have examined the rates of use in a population. The use of antibiotics for liveborn infants in LMIC was examined.

Design: The study, a planned prospective, observational secondary analysis of the A-PLUS randomised controlled trial of azithromycin, was conducted in Global Network sites in seven countries: Bangladesh, Pakistan, India (two sites), Kenya, Zambia, the Democratic Republic of Congo and Guatemala.

Objective: To describe the intrapartum and postpartum use of non-study antibiotics in low- and middle-income countries (LMICs) during the double-blinded NICHD Global Network Azithromycin in Labor (A-PLUS) trial.

Design: The antibiotic use sub-study was a planned prospective, observational sub-study of the A-PLUS trial.

Settings: The study was carried out in hospitals or health centres affiliated with eight sites of the Global Network for Women's and Children's Health Research (Global Network) in seven countries: Bangladesh, Pakistan, India (two sites), Kenya, Zambia, The Democratic Republic of the Congo (DRC) and Guatemala.
