Aim: To quantify the effects of 3% hypertonic saline (HTS) boluses on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in children.
Methods: A retrospective study of patients admitted to a regional neurosurgical children's intensive care unit.
Results: A total of 156 HTS boluses were given to children with traumatic brain injury. ICP decreased 6 mmHg (P < 0.01) and CPP increased 4 mmHg (P = 0.003) 1-h post-bolus. Effects persisted for 3 h post-dose ICP was 5 mmHg lower) and 4 h post-bolus CPP was 3 mmHg higher. ICP change was not associated with pre-bolus serum sodium concentration.
Conclusions: Hypertonic saline 3% at 5 mL/kg is an effective osmolar therapy for reducing ICP and increasing CPP in children for up to 3 h. '53-53' is a suitable guide - 5 mL/kg of 3% HTS will on average decrease ICP by at least 5 mmHg for 3 h. Pre-bolus serum sodium concentration is not correlated with effect size.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare inherited condition described worldwide and characterized by a wide spectrum of heterogeneity in terms of genotype and phenotype. How sacsin loss leads to neurodegeneration is still unclear, and current knowledge indicates that sacsin is involved in multiple functional mechanisms. We hence hypothesized the existence of epigenetic factors, in particular alterations in methylation patterns, that could contribute to ARSACS pathogenesis and explain the pleiotropic effects of SACS further than pathogenic mutations.

A hypertonic solution of Ibuprofen (Ibu) was designed to nebulize, associating a low concentration of Ibu with L-Arginine (AR), to increase solubility and serve as a nitric oxide donor. To provide preclinical research human bronchial epithelial cells derived from a cystic fibrosis patient homozygous for the ΔF508 CFTR mutation (CFBE41o-) and mouse RAW 264.7 macrophages were pre-treated with Ibu (10-100 μM), AR (20 and 200 μM), or the combination Ibu-AR (10-100 μM).

Solid supported lipid bilayers (SLBs) serve as an excellent platform for biophysical studies. However, the formation of highly negatively charged SLBs on negatively charged surfaces remains a challenge due to electrostatic repulsion. Here, we study the effects of ionic strength and osmotic stress on the formation of highly negatively charged SLBs on the silica surface.

Background: Intrathecal baclofen therapy can substantially improve symptoms in patients with severe spasticity owing to traumatic spinal cord injury, multiple sclerosis, cerebral paresis, or tethered cord syndrome. Problems associated with intrathecal catheters include migration, laceration, occlusion, or disconnection. Several case reports have described the management of catheter fragments.

Background: Low-volume hypertonic solutions, such as half-molar lactate (LAC), may be a potential treatment used for fluid resuscitation. This study aimed to evaluate the underlying cardiovascular effects and mechanisms of LAC infusion compared to sodium-matched hypertonic sodium chloride (SAL).
Methods: Eight healthy male participants were randomized in a controlled, single-blinded, crossover study.
