Inconsistency in ferritin reference intervals across laboratories: a major concern for clinical decision making.

Objectives: Iron deficiency anemia is a significant global health concern, diagnosed by measuring hemoglobin concentrations in combination with plasma ferritin concentration. This study investigated the variability in ferritin reference intervals among laboratories in the Netherlands and examined how this affects the identification of iron-related disorders.

Methods: Ferritin reference intervals from 52 Dutch ISO15189-certified medical laboratories were collected.

Determinants of Neurological Outcome Following Elective and Emergency Open Thoracoabdominal Aortic Aneurysm Repair-A Retrospective Multi-Center Study.

: This study aimed to evaluate and establish the incidence of all types of neurological complications at our high-volume reference center for open TAAA repair in the Netherlands and Germany. Additionally, we sought to identify predictors for various neurological complications. : This retrospective study was conducted in accordance with the STROBE guidelines, with the aim of reporting neurological outcomes for all patients who underwent open thoracoabdominal aortic aneurysm repair at two centers (Maastricht-Aachen) from 2000 to 2023, and to examine the association between these outcomes and pre- and perioperative parameters.

Asbestos Surveillance Program Aachen (ASPA): Cancer mortality among asbestos exposed power industry workers.

Background: The time between initial asbestos exposure and asbestos-related disease can span several decades. The Asbestos Surveillance Program aims to detect early asbestos-related diseases in a cohort of 8,565 power industry workers formerly exposed to asbestos.

Research Question: How does asbestos exposure patterns affect cancer mortality and the duration of latency until death?

Methods: A mortality follow-up was conducted with available vital status for 8,476 participants (99 %) and available death certificates for 89.

Pain-induced effects on the pupillary light response under high and low illumination conditions.

Objective: The present study investigated the impact of two different light intensities on the pain-modulated pupillary light response (PLR). Additionally, it aimed to demonstrate parasympathetic and sympathetic influences on PLR parameters in response to pain, as predicted by functional models.

Method: A total of 24 participants were included in a randomized, repeated-measures design.

Machine Learning-Based Prediction of Hemoglobinopathies Using Complete Blood Count Data.

Background: Hemoglobinopathies, the most common inherited blood disorder, are frequently underdiagnosed. Early identification of carriers is important for genetic counseling of couples at risk. The aim of this study was to develop and validate a novel machine learning model on a multicenter data set, covering a wide spectrum of hemoglobinopathies based on routine complete blood count (CBC) testing.
