Seltorexant for major depressive disorder.

Introduction: Preclinical and clinical pharmacologic evidence indicate that orexin systems are relevant to sleep-wake cycle regulation and dimensions of reward and cognition, providing the basis to hypothesizing that they may be effective as therapeutics in mental disorders. Due to the limited efficacy and tolerability profiles of existing treatments for Major Depressive Disorder (MDD), investigational compounds in novel treatment classes are needed; seltorexant, an orexin receptor antagonist, is a potential new treatment currently under investigation.

Areas Covered: Mechanisms implicated in MDD, including reward and sleep are first overviewed.

Severe palmoplantar keratoderma: a cutaneous complication from sub-optimally controlled type 2 diabetes.

Summary: Palmoplantar keratoderma (PPK), characterised by excessive epidermal thickening of the skin on the palms and/or plantar surfaces of the feet, can be hereditary or acquired. Here, we report a case of a 53-year-old woman with a history of sub-optimally controlled diabetes mellitus presenting with fevers and decreased Glasgow Coma Scale (GCS) to a tertiary hospital. She was diagnosed with diabetic ketoacidosis (DKA), with blood glucose at 40 mmol/L and ketones at 7 mmol/L, in the setting of a methicillin-sensitive Staphylococcus aureus necrotising soft tissue back infection.

Evolutionary characterization of the establishment of H6 influenza viruses in domestic geese in China: implications for the position of the host in the ecosystem.

Geese, both wild and domestic, are generally considered part of the natural reservoir for influenza A viruses. The highly pathogenic H5 Goose/Guangdong avian influenza virus lineage that is still causing outbreaks worldwide was first detected in domestic geese in 1996. However, while wild geese might have a somewhat restricted role in the influenza ecosystem, the role of domestic geese is little studied.

Risk factors and retreatment for relapse in childhood primary nephrotic syndrome treated with rituximab.

Background: The effectiveness of rituximab (RTX) for steroid-dependent/frequently relapsing nephrotic syndrome (SDNS/FRNS) in children is well documented. However, there are insufficient data on relapse risk factors. Additionally, the retreat regimen for relapsed children requires further investigation.

Brief Report: Evaluating Early-Stage Lung Cancer Survival Patterns in Patients at the Upper Age Limit for Lung Cancer Screening.

Introduction: Older individuals have an elevated lung cancer risk but may also have significant comorbidities that preclude curative treatment options and limit the survival benefits of screening. The objective of this study was to assess early-stage lung cancer survival patterns among those at the upper age limit for screening and identify older individuals who have potential to benefit from for lung cancer screening.

Methods: We identified all early stage (I or II) lung cancers diagnosed in Alberta, Canada between 2010 and 2020.
