Hospital-level volume in extracorporeal membrane oxygenation cases and death or disability at 6 months.

Objective: Extracorporeal membrane oxygenation (ECMO) is a high-risk procedure with significant morbidity and mortality and there is an uncertain volume-outcome relationship, especially regarding long-term functional outcomes. The aim of this study was to examine the association between ECMO centre volume and long-term death and disability outcomes.

Design Setting And Participants: This is a registry-embedded observational cohort study.

The effects of diatom polyunsaturated aldehydes on embryonic and larval zebrafish (Danio rerio).

Marine diatoms are pervasive in many planktonic and benthic environments and represent an important food source for a wide range of species. Some diatoms produce polyunsaturated aldehydes (PUAs) as defensive toxins. PUA exposure is known to reduce the fecundity of invertebrate grazers like copepods and echinoderm larvae, but little is known about the effects of PUAs on vertebrates.

Clemastine Induces Oligodendrocyte Progenitor Pool Exhaustion and Senescence in the Context of Chronic Demyelination in a Rabbit Model.

Objectives: Clemastine has emerged as a promising therapy for the restoration of neurologic function in patients with multiple sclerosis (MS). However, clemastine and other agents with prodifferentiative effects on oligodendrocyte progenitor cells (OPCs) in rodent models have underperformed in clinical trials. We hypothesized that the preclinical studies showed more robust effects because of the abundance of OPCs in rodent models.

The Impact of Polychlorinated Biphenyls on the Development of Zebrafish ().

Polychlorinated biphenyls (PCBs) are a group of 209 highly stable molecules that were used extensively in industry. Although their commercial use ceased in 1979, they are still present in many aquatic ecosystems due to improper disposal, oceanic currents, atmospheric deposition, and hydrophobic nature. PCBs pose a significant and ongoing threat to the development and sustainability of aquatic organisms.

Development of a Quality Indicator Set for the Optimal Acute Management of Moderate to Severe Traumatic Brain Injury in the Australian Context.

Background: The aim of this study was to develop a consensus-based set of indicators of high-quality acute moderate to severe traumatic brain injury (msTBI) clinical management that can be used to measure structure, process, and outcome factors that are likely to influence patient outcomes. This is the first stage of the PRECISION-TBI program, which is a prospective cohort study that aims to identify and promote optimal clinical management of msTBI in Australia.

Methods: A preliminary set of 45 quality indicators was developed based on available evidence.

Safe and effective use of the Celt ACD vascular closure device for rapid hemostasis following direct carotid puncture thrombectomy.

A man in his early 70s presented to the emergency department about 3.5 hours after acute onset right sided hemiplegia and aphasia. CT angiography confirmed an acute occlusion of the M1 segment of the left middle cerebral artery and severe, but stable, dissection of the aortic arch and a large dissecting aortic aneurysm extending into the innominate artery and beyond into the descending aorta.

IL-27 expression regulation and its effects on adaptive immunity against viruses.

IL-27, a member of the IL-6/IL-12 cytokine superfamily, is primarily secreted by antigen presenting cells, specifically by dendric cells, macrophages and B cells. IL-27 has antiviral activities and modulates both innate and adaptive immune responses against viruses. The role of IL-27 in the setting of viral infections is not well defined and both pro-inflammatory and anti-inflammatory functions have been described.

Actual Cost of Extracorporeal Cardiopulmonary Resuscitation: A Time-Driven Activity-Based Costing Study.

Objectives: To determine the actual cost and drivers of the cost of an extracorporeal cardiopulmonary resuscitation (E-CPR) care cycle.

Perspective: A time-driven activity-based costing study conducted from a healthcare provider perspective.

Setting: A quaternary care ICU providing around-the-clock E-CPR service for out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA) in Australia.

Twice weekly dosing with Sebelipase alfa (Kanuma®) rescues severely ill infants with Wolman disease.

Background: Sebelipase alfa (Kanuma®) is approved for patients with Wolman disease (WD) at a dosage of 3-5 mg/kg once weekly. Survival rates in the second of two clinical trials was greater, despite recruiting more severely ill patients, probably related to higher initial and maximal doses. We aimed to evaluate the effective pharmacokinetics and pharmacodynamics of Sebelipase alfa when administered to patients with severe WD at 5 mg/kg twice weekly, an intensive regimen which was not assessed in the trials.

Hepatomegaly and Splenomegaly: An Approach to the Diagnosis of Lysosomal Storage Diseases.

Clinical findings of hepatomegaly and splenomegaly, the abnormal enlargement of the liver and spleen, respectively, should prompt a broad differential diagnosis that includes metabolic, congestive, neoplastic, infectious, toxic, and inflammatory conditions. Among the metabolic diseases, lysosomal storage diseases (LSDs) are a group of rare and ultrarare conditions with a collective incidence of 1 in 5000 live births. LSDs are caused by genetic variants affecting the lysosomal enzymes, transporters, or integral membrane proteins.

A novel Ala469Val variant resulting in glycerol kinase deficiency with concurrent hepatoblastoma: A case report.

Glycerol kinase deficiency (GKD) is a rare X-linked condition where glycerol cannot be phosphorylated to glycerol-3-phosphate, a key component of gluconeogenesis. Clinical presentation varies widely. We present a novel variant of the responsible in a patient with concurrent hepatoblastoma, whose course was complicated by hypoglycemia.

Improving newborn screening test performance for metachromatic leukodystrophy: Recommendation from a pre-pilot study that identified a late-infantile case for treatment.

Metachromatic leukodystrophy (MLD) is a devastating rare neurodegenerative disease. Typically, loss of motor and cognitive skills precedes early death. The disease is characterised by deficient lysosomal arylsulphatase A (ARSA) activity and an accumulation of undegraded sulphatide due to pathogenic variants in the ARSA gene.

Association Between Early External Ventricular Drain Insertion and Functional Outcomes 6 Months Following Moderate-to-Severe Traumatic Brain Injury.

Traumatic brain injury (TBI) is a leading global cause of morbidity and mortality. Intracranial hypertension following moderate-to-severe TBI (m-sTBI) is a potentially modifiable secondary cerebral insult and one of the central therapeutic targets of contemporary neurocritical care. External ventricular drain (EVD) insertion is a common therapeutic intervention used to control intracranial hypertension and attenuate secondary brain injury.
