Article Synopsis
  • This study assessed the effectiveness of a set of interventions aimed at lowering medication errors during parenteral drug preparation in a neonatal and pediatric intensive care unit (NICU/PICU).
  • A clinical pharmacist and a pharmacy technician identified critical medication processes and introduced five key interventions, including improved drug labeling and centralized preparation for high-risk medications.
  • Following these interventions, the overall error rate decreased significantly from 1.32% to 0.78%, demonstrating that the strategies implemented successfully enhanced medication safety in the NICU/PICU.

: Of all adverse drug reactions, 35-45% are due to medication errors and would therefore be preventable. Thus, it is essential to implement effective strategies to prevent medication errors. However, it remains unclear whether medication reviews provide an additional benefit compared to medication reconciliation regarding medication safety.

Article Synopsis
  • MET amplification in EGFR-mutant non-small cell lung cancer (NSCLC) is a common resistance to EGFR inhibitors, and combining EGFR and MET inhibitors shows promise but has varied definitions of MET amplification.
  • In a study of 43 patients with MET copy number gain, those who received the combination of EGFR and MET inhibitors had an 82% clinical benefit rate and longer progression-free survival compared to those receiving MET inhibitors alone or standard of care.
  • The findings suggest that true MET amplification drives better outcomes with combination therapy, indicating a need for further research into how different types of MET copy number gain affect treatment response.

Article Synopsis
  • Differentiating acute liver failure (ALF) from acute-on-chronic liver failure (ACLF) is crucial for organ transplant referrals and urgency, particularly in patients with new liver disease.
  • A study measuring serum leptin levels in 160 critically ill liver disease patients found that ALF patients had significantly higher leptin concentrations compared to those with ACLF or decompensated advanced chronic liver disease (dACLD).
  • Serum leptin levels below 56 pg/mL were very effective in ruling out ALF, with a negative predictive value of 98.8%, and the leptin levels remained stable over the first 48 hours of ICU treatment.

EGFR exon 20 (EGFR Ex20) insertion mutations in non-small cell lung cancer (NSCLC) are insensitive to traditional EGFR tyrosine kinase inhibitors (TKIs). Mobocertinib is the only approved TKI specifically designed to target EGFR Ex20. We performed an international, real-world safety and efficacy analysis on patients with EGFR Ex20-positive NSCLC enrolled in a mobocertinib early access program.

Transition of care in geriatric patients is a complex and high risk process, particularly the continuation of discharge medication in primary care. We aimed to determine how general practitioners' management of geriatric patients' discharge medication is associated with rehospitalizations. A prospective monocentric cohort study was done in an acute geriatric inpatient clinic with six-months follow-up.

Background: ROS1 fusions are well treatable aberrations in NSCLC. Besides solvent-front mutations (SFM) in resistance to targeted therapy, small-scale ROS1 mutations are largely unknown. We exploratively analyzed the clinical and molecular characteristics of small-scale ROS1 mutations in NSCLC patients without activating ROS1 fusions or SFMs.

Telepharmacy is used to bridge the persisting shortage of specialist ward-based pharmacists, particularly in intensive care units (ICU). During the coronavirus disease 2019 (COVID-19), pharmacotherapy was rapidly developed, which resulted in multiple changes of guidelines. This potentially led to a differing risk for drug-related problems (DRPs) in ICUs.

Objectives: Resistance to MET inhibition occurs inevitably in MET-dependent non-small cell lung cancer and the underlying mechanisms are insufficiently understood. We describe resistance mechanisms in patients with MET exon 14 skipping mutation (METΔ), MET amplification, and MET fusion and report treatment outcomes after switching therapy from type I to type II MET inhibitors.

Materials And Methods: Pre- and post-treatment biopsies were analysed by NGS (next generation sequencing), digital droplet PCR (polymerase chain reaction), and FISH (fluorescense in situ hybridization).

Background: Anorexia nervosa (AN) is a severe psychiatric disease that often takes a chronic course due to insufficient treatment options. Emerging evidence on the gut-brain axis offers the opportunity to find innovative treatments for patients with psychiatric disorders. The gut microbiome of patients with AN shows profound alterations that do not completely disappear after weight rehabilitation.

Paediatric patients are more vulnerable to be harmed by medication errors compared to adults due to pharmacokinetic and pharmacodynamic changes in their development, individual dosing calculations, and manipulation of ready to-use products intended for adult patients. According to the Institute of Safe Medication Practices, there are some "drugs that bear a heightened risk of causing significant patient harm when they are used in error"; these drugs are called high-alert medications (HAM). The two-step survey among paediatric clinical expert pharmacists presented here aimed to compile a nation-wide HAM list.

Asparaginases are common chemotherapeutic agents used for the treatment of acute lymphoblastic leukemia as a single or combinational therapy. Accompanying hepatotoxicity makes its use in elderly patients with pre-conditions, as obesity or other hepatopathies, difficult. Various hepatoprotective compounds like, L-carnitine, are discussed to ameliorate the induced hepatotoxicity.

Soluble receptor activator of nuclear factor κ B ligand (sRANKL) is a member of the tumor necrosis factor receptor superfamily, and therefore, involved in various inflammatory processes. The role of sRANKL in the course of bone remodeling via activation of osteoclasts as well as chronic disease progression has been described extensively. However, the potential functional importance of sRANKL in critically ill or septic patients remained unknown.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) are beneficial in surgical settings, they may however lead to adverse drug reactions including decreased renal function, a risk, which is exacerbated by combination with other nephrotoxics, and particularly when NSAIDs are given as part of a so-called 'Triple Whammy' (TW) with diuretics and renin-angiotensin system blockers. The objective of this study was to identify the prevalence of TW-prescriptions in a surgical inpatient setting and to document the changes in renal function after pharmacist recommendations. A prospective, observational single centre pilot study was performed using a series of eleven weekly Point-Prevalence Analyses (PPA).
