Objectives: Ambulance diversion has emerged as a strategy to address Emergency Department (ED) overcrowding, but the question of when or whether diversion should be triggered is widely debated. Although the positive and adverse impacts of diversion have been primarily studied using quantitative data, little is known about the experience and perceptions of key stakeholders involved in diversions. Our study aims to explore the challenges and impacts of ambulance diversion as experienced by key stakeholders and their suggestions for improving the diversion process.

Article Synopsis
  • Assessing glomerular filtration rate (GFR) is essential for kidney disease management, but current methods, particularly estimated GFR (eGFR), can have significant errors affecting patient care.
  • Researchers propose using a panel of multiple filtration markers, alongside non-GFR determinants, to enhance the accuracy of these estimates, building on previous findings that cystatin C improves eGFR precision.
  • Initial evaluations indicate that applying techniques like outlier identification and transfer learning can significantly improve eGFR accuracy, even in populations where traditional methods struggle.

Survivors of COVID-19 are susceptible to diminished health-related quality of life (HRQoL) and adverse psychological health, which may be exacerbated by their experiences of fear and the impact of the pandemic itself. This study aims to identify distinct fear and impact patterns related to the COVID-19 pandemic among survivors through latent profile analysis (LPA) and examine the associations of fear and impact patterns with post-traumatic stress symptoms (PTSS) and HRQoL. A total of 5,890 Vietnamese COVID-19 survivors completed the COVID-19 Impact Battery- Disability Scale (CIB-D), the Fear of COVID-19 Scale (FCoV-19 S), the Impact of Event Scale-Revised for PTSS, and the 36-Item Short Form Survey (SF-36) for HRQoL.

Background And Aim: Endoscopic submucosal dissection (ESD) is considered the best modality for achieving en bloc resection of larger neoplastic mucosal lesions in the upper and lower gastrointestinal (GI) tract. Multiple devices are available for ESD, and refinements continue to be made to develop devices that improve the safety and efficiency of performing ESD. Submucosal injection with viscous fluids like glycerol, which prolong submucosal expansion, could facilitate the procedure.

  • The scoping review commissioned by ILCOR focused on the treatment and outcomes of obese patients in cardiac arrest, highlighting the growing concern of obesity's impact on health.
  • A total of 36 studies were analyzed, with findings indicating that while adult outcomes varied, obese children generally showed worse survival rates and neurological outcomes compared to their normal-weight peers.
  • The review concluded that though results were inconsistent, there's no immediate need to change standard CPR protocols, but it noted that resuscitation efforts might take longer for obese adults, which could affect resources.

NPJ Aging

November 2024

Neuroscience and Behavioural Diseases and Eye-ACP, Centre for Vision Research, Duke-NUS Medical School, Singapore, Singapore.

There is a growing need to better characterise senescent cells in the CNS and retina. The recently published SenMayo gene panel was developed to identify transcriptomic signatures of senescence across multiple organ systems, but the retina was not included. While other approaches have identified senescent signatures in the retina, these have largely focused on experimental models in young animals.

The changing treatment landscape of EGFR-mutant non-small-cell lung cancer.

Nat Rev Clin Oncol

November 2024

Department of Medical Oncology, Shanghai East Hospital, Tongji University School of Medicine, Shanghai, China.

The discovery of the association between EGFR mutations and the efficacy of EGFR tyrosine-kinase inhibitors (TKIs) has revolutionized the treatment paradigm for patients with non-small-cell lung cancer (NSCLC). Currently, third-generation EGFR TKIs, which are often characterized by potent central nervous system penetrance, are the standard-of-care first-line treatment for advanced-stage EGFR-mutant NSCLC. Rational combinations of third-generation EGFR TKIs with anti-angiogenic drugs, chemotherapy, the EGFR-MET bispecific antibody amivantamab or local tumour ablation are being investigated as strategies to delay drug resistance and increase clinical benefit.
