Emerging nanomaterials incorporated in membranes for polyfluoroalkyl substances (PFAS) removal from water: A review.

Water purification become more challenging day by day, due to novel anthropogenic pollutants such as per- and polyfluoroalkyl substances (PFAS) used in nonstick cookware, firefighting foams, packaging etc. PFAS has adverse effects on human health and ecosystem and their physicochemical properties and unique molecular structures make the conventional water treatment methods more challenging. Among the novel PFAS removal technologies, nanomaterials incorporated in membranes are regarded as promising membrane technology for the treatment of PFAS.

Use of Opioids and Nonopioid Analgesics to Treat Pediatric Postoperative Pain in the Emergency Department.

Objectives: The incidence, demographic characteristics, and treatment approaches for pediatric patients who present to the ED with a primary complaint of postoperative pain have not been well described. The purpose of this study was to describe opioid and nonopioid prescribing patterns for pediatric patients evaluated for postoperative pain in the Emergency Department (ED).

Methods: Pediatric Health Information System is an administrative database of encounter-level data from 48 children's hospitals.

Fasting with diabetes: a prospective observational study.

Objectives: To determine the proportion of diabetic patients who develop adverse glycaemic events when fasting regularly.

Design: Prospective observational study conducted at a tertiary care hospital in South Asia. Five hundred and twenty-three patients were assessed for eligibility, and 150 were included in the final analysis.

Glioma stem cell maintenance: the role of the microenvironment.

Glioblastomas are highly lethal cancers for which conventional therapies provide only palliation. The cellular heterogeneity of glioblastomas is manifest in genetic and epigenetic variation with both stochastic and hierarchical models informing cellular phenotypes. At the apex of the hierarchy is a self-renewing, tumorigenic, cancer stem cell (CSC).
