Melatonin: A Review of the Evidence for Use in Hospital Settings.

New onset insomnia is often experienced by patients during hospitalization due to environmental disruptions, pain and increased patient care activities. Patient distress arising from poor sleep quality and quantity often results in the prescribing of hypnotics. Melatonin use in hospital settings is common and is increasingly used for off label indications including primary insomnia in those aged < 55 years, prevention of delirium and to facilitate benzodiazepine discontinuation.

Complex Genetic Framework in Familial Amyotrophic Lateral Sclerosis With a C9ORF72 Mutation: A Case Report.

A significantly diverse clinical presentation of amyotrophic lateral sclerosis (ALS), even in its best-studied familial form, continues to hinder current efforts to develop effective disease-modifying drugs for the cure of this rapidly progressive, fatal neuromuscular disease. We have previously shown that clinical heterogeneity of sporadic ALS (sALS) could be explained, at least in part, by its polygenic nature as well as by the presence of mutated genes linked to non-ALS neurological diseases and genes known to mediate ALS-related pathologies. We hypothesized that a similar genetic framework could also be present in patients with familial ALS (fALS).

Slow-Release Pharmaceutical Implants in Ecotoxicology: Validating Functionality across Exposure Scenarios.

Pharmaceutical contaminants have spread in natural environments across the globe, endangering biodiversity, ecosystem functioning, and public health. Research on the environmental impacts of pharmaceuticals is growing rapidly, although a majority of studies are still conducted under controlled laboratory conditions. As such, there is an urgent need to understand the impacts of pharmaceutical exposures on wildlife in complex, real-world scenarios.

Patients' Perceptions of the Efficacy, Safety, and Quality of the Evidence of Medicinal Cannabis: A Survey of Australian Cancer Patients.

Introduction: Despite the increased demand for medical cannabis (MC), MASCC guidelines state that there is insufficient evidence of its efficacy and safety. Although research has explored medical professionals' perceptions of MC, there is to our knowledge minimal research exploring patients' perceptions, particularly in an Australian cancer setting.

Methods: A survey of Australian cancer patients attending oncology outpatient clinics was performed.

Fine-tuning of gene expression through the Mettl3-Mettl14-Dnmt1 axis controls ESC differentiation.

The marking of DNA, histones, and RNA is central to gene expression regulation in development and disease. Recent evidence links N6-methyladenosine (mA), installed on RNA by the METTL3-METTL14 methyltransferase complex, to histone modifications, but the link between mA and DNA methylation remains scarcely explored. This study shows that METTL3-METTL14 recruits the DNA methyltransferase DNMT1 to chromatin for gene-body methylation.
