Sex differences in the pharmacokinetics of anticancer drugs: a systematic review.

ESMO Open

December 2024

Department of Pharmacology, Gustave Roussy, Villejuif, France.

Article Synopsis
  • The study highlights that body weight and sex can significantly impact how anticancer drugs are processed in the body, yet the extent of these differences remains unclear.
  • A systematic review of 112 studies identified significant pharmacokinetic (PK) differences for 14 out of 99 examined anticancer agents, although no studies currently assess how these differences impact drug efficacy or safety.
  • The findings suggest that developing sex-specific dosing strategies for anticancer drugs could improve their risk-benefit ratio for patients.

Assessing the response to systemic therapy in neuroendocrine tumors (NET) is challenging since morphological imaging response is often delayed and not necessarily reflective of clinical benefit. Peptide receptor radionuclide therapy (PRRT) has a complex mechanism of action, further complicating response assessment. In response to these challenges, the European Neuroendocrine Tumor Society (ENETS) Theranostics Task Force conducted a statement-based survey among experts to identify the current landscape and unmet needs in PRRT response assessment.

Aims: Mutations affecting exon 3 of the β-catenin () gene result in constitutive activation of WNT signalling and are a diagnostic hallmark of several tumour entities including desmoid-type fibromatosis. They also define clinically relevant tumour subtypes within certain entities, such as endometrioid carcinoma. In diagnostics, β-catenin immunohistochemistry is widely used as a surrogate for mutations.

Article Synopsis
  • Geometric optical illusions (GOIs) highlight mismatches between what we see and the actual physical stimuli, allowing researchers to explore how sensation and perception interact.
  • A study conducted with 30 adults revealed that different physical properties of GOIs have varying effects on perceptual biases, and these effects can interact in complex ways.
  • By combining psychophysics with computational modeling of the primary visual cortex, the researchers found that certain adjustments in neural parameters could replicate human perceptual biases, suggesting that different physical attributes work together to create a GOI and offering insights into the mechanisms behind perception.

Acetaminophen is a common over-the-counter medication that recently gained substantial media attention regarding its use by pregnant individuals. In this clinical perspective, we discuss the strengths and limitations of the published literature on the effect of maternal acetaminophen use in pregnancy on the child's risk of developing attention-deficit and hyperactivity disorder (ADHD) and autistic spectrum disorder (ASD). Studies included were specifically selected on the basis of the quality and validity of ADHD or ASD outcome definitions.

Secondary peritonitis with intra-abdominal abscesses (IAA) is difficult to treat because of the supposed low rate of penetration of antimicrobial drugs at the site of infection. However, clinical data about the actual bioavailability of antimicrobial drugs in IAA are scarce. This prospective observational study aimed at assessing the drug penetration in IAA of the antibiotics (piperacillin-tazobactam, carbapenems) and antifungals (fluconazole, echinocandins) that are usually recommended for the treatment of intra-abdominal infections.

Article Synopsis
  • Early worsening of plasma lipid levels (EWL), defined as a ≥5% change after one month, is linked to long-term lipid issues in patients treated with certain psychotropic medications.
  • This study identified that low initial levels of total cholesterol, LDL-C, and triglycerides, along with high HDL-C levels, are significant risk factors for EWL, and integrating specific genetic variations (SNPs) can enhance prediction accuracy.
  • Overall, clinical and genetic factors are important for predicting EWL and developing new-onset dyslipidaemia, suggesting the need for larger studies to improve these predictive models for clinical use.

Background: Clinical supervision by psychiatric liaison clinicians is frequently provided in medical settings such as oncology and palliative care, but rarely in endocrinology. Consequently, the specific psychosocial issues faced by endocrinologists in their daily clinical practice and how they deal with them remain largely unknown. We aimed to explore individual supervisions of endocrinologists to gain insight into what kind of clinical situations they present, how they react to them and how this is worked through in supervision.

  • The Avalanche Victim Resuscitation Checklist (AVRC) was created to enhance the management of avalanche victims experiencing cardiac arrest, as prior compliance with international guidelines was poor.
  • A study over ten years examined the effectiveness of the AVRC, revealing significant improvements in guideline compliance (from 59% to 95%) and complete documentation after its implementation.
  • The findings suggest that while the AVRC enhances patient management for critically buried victims, further quality improvements are needed for those buried for extended periods.

Given the association of Epstein-Barr virus (EBV) with subjective perception of fatigue and demyelination in clinical conditions, the question about potential subclinical effects in the adult general population remains open. We investigate the association between individuals' EBV immune response and perceived fatigue in a community dwelling cohort (n = 864, age 62 ± 10 years old; 49% women) while monitoring brain tissue properties. Fatigue levels are assessed with the established fatigue severity scale, the EBNA-1 and VCA p18 immunoglobulin G (IgG) chronic response - with multiplex serology and the estimates of local brain volume, myelin content, and axonal density - using relaxometry- and multi-shell diffusion-based magnetic resonance imaging (MRI).
