Article Synopsis
  • This study presents electrostatic spraying as an innovative method to create nanoparticles for poorly water-soluble drugs, improving particle size distribution compared to traditional spray-drying methods.
  • Regorafenib was used as a model drug, and electrostatic spray-dried nanoparticles (ESDN) showed smaller, more uniform sizes, with enhanced solubility and faster release in water than conventional spray-dried nanoparticles (CSDN).
  • ESDN also exhibited greater cytotoxicity in cancer cells and significantly improved oral bioavailability and antitumor effects, indicating its potential for better drug delivery systems.

Article Synopsis
  • A novel technique was developed to improve the water solubility and oral bioavailability of aceclofenac using different nanoparticle systems, with sodium carboxymethylcellulose (Na-CMC) proving to be the most effective polymer.
  • Various methods like spray-drying were used to create different solid dispersions with aceclofenac and Na-CMC, which resulted in nanoparticles with distinct properties such as size and morphology.
  • The study found that the self-nanoemulsifying drug delivery system (SNEDDS) had the best overall performance in enhancing drug solubility and bioavailability, making the nanoparticle screening method a valuable tool for improving other poorly soluble compounds.

Article Synopsis
  • A study in Korea examined how physical activity (PA) levels affect healthcare usage, specifically emergency department visits and hospitalizations, among patients with chronic obstructive pulmonary disease (COPD).
  • The research involved a large cohort of 3308 COPD patients and 293,358 non-COPD individuals, analyzing data from 2009 to 2017.
  • Findings revealed that COPD patients had significantly higher risks of healthcare visits across all PA levels, especially in those who were sedentary, and increasing PA by just 500 MET-min/week could lower these risks.

Article Synopsis
  • The study investigates the relationship between genetic polymorphisms and the development of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in female osteoporosis patients undergoing treatment.
  • Out of 123 patients, 56 developed BRONJ, with specific genetic markers (rs2946385 and rs10020457) initially showing potential association, though not significant in later analysis.
  • Factors like older age (≥70 years) and longer bisphosphonate use (≥60 months) were linked to higher BRONJ risk, indicating the need for personalized treatment approaches based on genetic predispositions.

Article Synopsis
  • The study examines the link between anxiety and smartphone addiction among Korean adolescents, highlighting that excessive smartphone use can harm physical, social, and psychological health.
  • Using a survey of 1,733 adolescents, the research found that 20.1% of participants were categorized as high-risk for smartphone addiction, revealing significant differences in anxiety levels based on addiction risk.
  • Factors like poor self-reported health, fewer close friends, and substance use (caffeine and alcohol) were connected to higher anxiety, emphasizing the need for strategies to prevent smartphone addiction for better mental health.

There are various trigger tools for detecting adverse drug events (ADEs), however, a drug-related emergency department (ED) visit trigger tool (DrEDTT) has not yet been developed. We aimed to develop and validate a DrEDTT with a multi-center cohort. In this cross-sectional study, we developed the DrEDTT consisting of 28 triggers through a comprehensive literature review and three phase expert group discussion.

Although specialized pharmacists have been suggested to be essential members of antimicrobial stewardship programs (ASPs), not all hospitals in Korea operate ASPs with pharmacists involved. We aimed to evaluate the association of involvement of clinical pharmacists as team members of multidisciplinary ASPs with the incidence of antimicrobial-related adverse drug events (ADEs). Five tertiary teaching hospitals participated in this retrospective cohort study.

Although an elevated INR is highly associated with an increased risk of warfarin-associated bleeding, it has been reported that some patients also experience bleeding complications at therapeutic INRs. TGF-β1 polymorphisms has been reported to cause vascular malformations, resulting in bleeding complications, but there are few published genetic studies regarding bleeding complications in patients on warfarin therapy. This study aimed to determine if there is an association between transforming growth factor beta-1 (TGF-β1) polymorphisms and bleeding complications in patients who maintain international normalized ratios (INRs) of 2.

Introduction: The aim of this study is to identify the association between Attention Deficit Hyperactivity Disorder (ADHD) proneness and aggressive propensity in adolescents.

Methods: A quantitative, large-scale, cross-sectional study was performed from April to May 2016 in Korea. The survey questionnaire included overall health behaviors, as well as scales for assessing ADHD proneness (revised short form of the Conners-Wells Adolescent Self-Report Scale; CASS[S]) and aggressive behavior (Buss-Perry Aggression Questionnaire; BPAQ) in adolescents.

Background: Considering the limited generalizability of previous anticholinergic burden scales, the Korean Anticholinergic Burden Scale (KABS) as a scale specific to the Korean population was developed. We aimed to validate the KABS by detecting the associations between high anticholinergic burden, measured with the KABS, and emergency department (ED) visits compared to the pre-existing validated scales in older Korean adults.

Methods: A nested case-control study was conducted using national claims data.

Article Synopsis
  • The study investigated how genetic variations (polymorphisms) in the GRK5 gene affect the effectiveness and side effects of ritodrine treatment in 162 pregnant women experiencing preterm labor.
  • Specific genetic variants (rs4752292 and rs1020672) were linked to lower chances of delivery and higher rates of adverse drug events compared to women with the wild-type gene, suggesting a significant impact on treatment outcomes.
  • Additional factors such as gestational age and body weight also played a role in delivery timing and the occurrence of adverse effects, indicating that both genetics and individual characteristics influence treatment response in this context.
