Much of sexual dimorphism is likely due to sex-biased gene expression, which results from differential regulation of a genome that is largely shared between males and females. Here, we use allele-specific expression to explore cis-regulatory variation in Drosophila melanogaster in relation to sex. We develop a Bayesian framework to infer the transcriptome-wide joint distribution of cis-regulatory effects across the sexes.

Article Synopsis
  • A study investigated the prevalence and factors linked to CNS-active polypharmacy in older adults (60+) in Buenos Aires, finding that 7.1% of patients were using three or more CNS-active medications.
  • The research included 63,857 patients, revealing that common combinations of medications involved antidepressants, antipsychotics, and benzodiazepines, particularly in those with mental health disorders.
  • Conditions like frontotemporal dementia and schizophrenia significantly increased the odds of polypharmacy, highlighting the need for strategies to manage medication use in older populations.

Orofacial granulomatosis is a rare disorder that is heterogeneously defined in the published literature. Herein, we describe a patient with orofacial granulomatosis with clinical and histologic evidence, discuss differential diagnoses, and offer clinical pearls for diagnosing and assessing this disorder. Our case provides support that orofacial granulomatosis is a distinct disorder as opposed to a sequela of other systemic granulomatous diseases.

Introduction: Standardized screening, objective evaluation, and management of behavioral health conditions are major challenges in primary care. The Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire (PHQ-9), and Mood Disorder Questionnaire (MDQ) provide standardized screening and symptom management tools for generalized anxiety disorder (GAD), major depressive disorder (MDD), and Mood Disorders (MD), respectively. This study explores family physicians' knowledge, attitudes, and practices regarding the utilization of GAD-7, PHQ-9, and MDQ in outpatient primary care offices.

Article Synopsis
  • Lung cancer is a major global health issue, causing over 1.8 million deaths annually, with surgery being a highly effective treatment for early-stage cases.
  • This study analyzed the metabolic changes in serum samples from lung cancer patients before and after surgery, using advanced techniques to compare their profiles at two time points with those of healthy individuals.
  • Twenty-two metabolites were found to be altered in patients pre-surgery, with some returning to normal levels months after surgery, while others remained altered, providing valuable insights into treatment responses and potential cancer recurrence detection.
