Pharmacokinetic and Metabolomic Studies with BBT-059 in Nonhuman Primates Exposed to Total-Body Gamma Radiation.

BBT-059 is a long-acting PEGylated interleukin-11 analog that has been shown to have hematopoiesis-promoting and anti-apoptotic attributes, and is being studied as a radiation countermeasure for the hematopoietic acute radiation syndrome (H-ARS). This potential countermeasure has been demonstrated to enhance survival in irradiated mice. To investigate the toxicity and safety profile of this agent, 14 nonhuman primates (NHPs, rhesus macaques) were administered two different doses of BBT-059 subcutaneously 24 h after 4 Gy total-body irradiation and were monitored for the next 60 days postirradiation.

Primary Arthrodesis or Open Reduction and Internal Fixation for Lisfranc Injuries: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Lisfranc injuries are often managed surgically with primary arthrodesis (PA) or open reduction and internal fixation (ORIF); however, neither approach has been shown to be superior. This systematic review and meta-analysis assessed randomized controlled trials (RCTs) to compare the functional and surgical outcomes of PA and ORIF in the treatment of Lisfranc injuries.

Methods: This study was performed as per the PRISMA protocol.

A qualitative exploratory study into medical, nursing and allied health professional experiences of elective withdrawal of non-invasive ventilation in a motor neurone disease cohort.

Rationale, Aims And Objectives: With absence of a cure, the mainstay of management for patients with motor neurone disease (MND) is holistic supportive care and symptom control. Non-invasive ventilation (NIV) can provide relief from distressing dyspnoea which often accompanies progressive respiratory muscle weakness. Some patients using NIV will become dependent on it, with a small proportion of these patients going on to request withdrawal.
