Objective: To assess the performance of Pediatric Risk of Mortality (PRISM) III and Pediatric Index of Mortality (PIM) 2 scores in the pediatric intensive care unit.
Methods: A retrospective cohort study. Data were retrospectively collected from medical records of all patients admitted to the pediatric intensive care unit of a cancer hospital from January 2017 to June 2018.
Results: The mean PRISM III score was 15, and PIM 2, 24%. From the 338 studied patients, 62 (18.34%) died. The PRISM III estimated mortality was 79.52 patients (23.52%) and for PIM 2 80.19 patients (23.72%), corresponding to a standardized mortality ratio (95% confidence interval: 0.78 for PRISM II and 0.77 for PIM 2). The Hosmer-Lemeshow chi-square test was 11.56, 8df, 0.975 for PRISM II and 0.48, 8df, p = 0.999 for PIM 2. The area under the Receiver Operating Characteristic curve was 0.71 for PRISM III and 0.76 for PIM 2.
Conclusion: Both scores overestimated mortality and have shown a regular ability to discriminate between survivors and non-survivors. Models should be developed to quantify the severity of cancer pediatric patients in Pediatric Intensive Care Units and to predict the mortality risk accounting for their peculiarities.

Heterogeneity of reduced FEV in early adulthood: A looking forward, looking backwards analysis.
Respirology
January 2025
Institut d'Investigacions Biomediques August Pi i Sunyer (IDIBAPS), Barcelona, Spain.
Background: Some individuals never achieve normal peak FEV in early adulthood. It is unknown if this is due to airflow limitation and/or lung restriction.
Methods: To investigate this, we: (1) looked forward in 19,791 participants in the Dutch Lifelines general population cohort aged 25-35 years with 5-year follow-up; and (2) looked backwards in 2032 participants in the Swedish BAMSE birth cohort with spirometry at 24 years of age but also at 16 and/or 8 years.
Investigation of the Sensitivity of Acoustic Emission to the Differentiation Between Mode I, II, and III Fracture in Bulk Polymer Materials.
Polymers (Basel)
January 2025
Department of Mechanics of Materials and Constructions (MeMC), Vrije Universiteit Brussel, B-1050 Brussels, Belgium.
There is very limited research in the literature investigating the way acoustic emission signals change when polymer materials are undergoing different fracture modes. This study investigates the capability of acoustic emission to recognize the fracture mode through acoustic emission parameter analysis, and can be considered the first-ever study which examines the impact of different loading conditions, i.e.

However, some of these children may experience poor outcomes, including death. However, it is necessary to predict the prognosis for critically ill patients as early as possible to commence triage as well as an early and effective intervention to prevent mortality.

December 2025
Department of Dermatology, King Abdullah University Hospital, Faculty of Medicine, Jordan University of Science and Technology, Irbid, Jordan.
Background/objectives: This study aims to investigate the demographic and clinical characteristics of rosacea within the North Jordan population, focusing on Fitzpatrick skin types III and IV. The intent is to address gaps in dermatological research concerning ethnic and racial variations in rosacea's presentation and impact.
Methods: We conducted a retrospective cohort analysis at the dermatology department of King Abdullah University Hospital, North Jordan, reviewing medical records of patients diagnosed with rosacea from January 2013 to December 2023.
