The Effects of Perfluorooctanesulfonic acid (PFOS) on Human Umbilical Vein Endothelial Cells (HUVECs) Proliferation and Gene Expression and its Implications on Fetal Development.

Polyfluoro-alkyl substances (PFAS) are widely distributed environmental contaminants linked to human toxicity and developmental delays, especially low birthweight (LBW). In this study, Human Umbilical Vein Endothelial Cells (HUVECs) were exposed to the PFAS perfluorooctanesulfonic acid (PFOS). After 48-hours, their proliferation, and differential gene expression were assessed.

Development of tetracycline analogues with increased aqueous stability for the treatment of mycobacterial infections.

Tetracycline analogs from the minocycline family have recently shown promise for the treatment of non-tuberculous mycobacterial infections. However, current tetracycline and minocycline therapeutics can be limited by tolerability, stability, or inactivation by TetX. In this study, a series of novel 9-heteroaryl substituted minocycline analogs were designed and synthesized, which resulted in analogs with good in vitro activity against Mycobacterium tuberculosis and Mycobacterium abscessus, stability in water for more than 7 days, avoidance of TetX inactivation in M.

Population-health impact of new drugs recommended by the National Institute for Health and Care Excellence in England during 2000-20: a retrospective analysis.

Background: Health systems experience difficult trade-offs when paying for new drugs. In England, funding recommendations by the National Institute for Health and Care Excellence (NICE) for new drugs might generate health gains, but inevitably result in forgone health as the funds cannot be used for alternative treatments and services. We aimed to evaluate the population-health impact of NICE recommendations for new drugs during 2000-20.

Physiological Assessment of ECCOR on the Work of Breathing in Exacerbations of COPD.

Rationale: The impact of extracorporeal carbon dioxide removal (ECCOR) on work of breathing and aeration in exacerbations of chronic obstructive pulmonary disease (AECOPD) is poorly understood.

Objectives: The study explores the impact of non-invasive ventilation (NIV) and ECCOR on respiratory drive, effort and distribution of ventilation in AECOPD.

Methods: Patients enrolled in a randomised controlled study of the addition of ECCOR to NIV compared with NIV underwent oesophageal pressure measurement, electrical impedance tomography and parasternal electromyography.

Predictors of End-of-Life Care in Nonelderly Adults With Severe Traumatic Brain Injury.

Introduction: Older age is a well-established risk factor for withdrawal of life-sustaining therapy (WDLST) and discharge to hospice (DH) in traumatic brain injury (TBI). However, a paucity of data exists in identifying factors associated with end-of-life (EoL) care in younger patients with TBI. We sought to identify hospital and patient factors associated with EoL care and timing of EoL care in younger adults with severe TBI.
