JAGN1 (Jagunal-homolog1) is a ER-resident transmembrane protein which is part of the early secretory pathway and granulocyte colony-stimulating factor receptor mediated signaling. Autosomal recessively inherited variants in the JAGN1 gene lead to congenital neutropenia, early-onset bacterial infections, aphthosis and skin abscesses due to aberrant differentiation and maturation of neutrophils. In addition, bone metabolism disorders and a syndromic phenotype, including facial features, short stature and neurodevelopmental delay, have been reported in affected patients.

Background: White matter hyperintensities (WMH) have been implicated in the pathogenesis of neuropsychiatric symptoms of dementia but the functional significance of WMH in specific white matter (WM) tracts is unclear. We investigate whether WMH burden within major WM fibre classes and individual WM tracts are differentially associated with different neuropsychiatric syndromes in a large multicentre study.

Method: Neuroimaging and neuropsychiatric data of seven memory clinic cohorts through the Meta VCI Map consortium were harmonised.

Background: Noncompressible truncal hemorrhage is a major contributor to preventable deaths in trauma patients and, despite advances in emergency care, still poses a big challenge.

Objectives: This study aimed to assess the clinical efficacy of trauma resuscitation care incorporating Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) compared to standard care for managing uncontrolled torso or lower body hemorrhage.

Methods: This study utilized a target trial design with a matched case-control methodology, emulating randomized 1 : 1 allocation for patients receiving trauma resuscitation care with or without the use of REBOA.

 - a large-scale dataset of 3D medical shapes for computer vision.

Biomed Tech (Berl)

December 2024

Institute for Artificial Intelligence in Medicine (IKIM), University Hospital Essen (AöR), Essen, Germany.

Objectives: The shape is commonly used to describe the objects. State-of-the-art algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from the growing popularity of ShapeNet (51,300 models) and Princeton ModelNet (127,915 models).

Is human oversight to AI systems still possible?

N Biotechnol

December 2024

Information Science and Machine Learning Group, Diagnostic and Research Institute of Pathology, Medical University Graz, Austria.

The rapid proliferation of artificial intelligence (AI) systems across diverse domains raises critical questions about the feasibility of meaningful human oversight, particularly in high-stakes domains such as new biotechnology. As AI systems grow increasingly complex, opaque, and autonomous, ensuring responsible use becomes a formidable challenge. During our editorial work for the special issue "Artificial Intelligence for Life Sciences", we placed increasing emphasis on the topic of "human oversight".

Article Synopsis
  • Enfortumab vedotin (EV) is a new treatment option for patients with advanced urothelial carcinoma who haven't responded to other therapies.
  • A study involving 128 patients in Austria showed an objective response rate of 31%, with median progression-free survival of 4.8 months and overall survival of 10.75 months.
  • The treatment was found to be feasible and effective, with an acceptable safety profile, although lower efficacy was noted compared to earlier trials, likely due to the patient population being in later therapy lines.

Objective: Shared decision-making is one promising approach to promoting recovery and person-centred care but seems challenging for implementation in clinical practice. This study aimed to explore how patients and health professionals experience shared decision-making and its facilitators and barriers.

Methods: A multiple qualitative case study design was chosen, using a constant comparative method.

Purpose: To evaluate the performance and clinical outcome of vertical and horizontal bone augmentation (VHBA) in posterior maxillary regions combining lateral window sinus floor elevation (LWSFE) with a horizontal bone shell technique applying the maxillary facial sinus wall as a bone plate.

Materials And Methods: In 18 patients, LWSFE was combined with a horizontal bone shield augmentation procedure utilizing the maxillary facial sinus bone wall as a lateral bone plate. Both the sinus cavity and the lateral bone box created were grafted with a mixture of autogenous bone/venous blood and bovine bone mineral.

Purpose: This study aims to identify a combination of clinical, demographic, and patient competence determinants of patients' communication with doctors and nurses in an international sample of cancer patients.

Methods: For our cross-sectional study, cancer patients assessed their communication with their doctors or nurses at the start of their treatment. Patients completed EORTC communication questionnaire QLQ-COMU26 to assess ten areas of communication with their doctor or nurses plus another item to assess how competent they felt when communicating with professionals.

This work explores the complex hydrodynamics in magnetophoretic microfluidic processes, focusing on the interplay of forces and particle concentrations. The study employs a combined simulation and experimental approach to investigate the impact of magnetophoresis on magneto-responsive nanoparticles (MNPs) and their environment, including non-magneto-responsive nanoparticles (non-MNPs) in a microfluidic system. Our findings reveal that the motion of MNPs induces a hydrodynamic convective motion of non-MNPs, significantly affecting the separation efficiency and purity of the particles.

Solid organ transplantation continues to be the only or most efficient therapeutic solution for several end-stage diseases. The success of such transplantation is largely dependent on the swift transportation of organs from donors to recipients, as Cold Ischemia Time (CIT) plays a critical role in determining the recipient's medical outcome. This study explores the potential of Advanced Air Mobility (AAM) in the context of organ transplantation in Austria and Germany.

Cerebral white matter hyperintensity volumes: Normative age- and sex-specific values from 15 population-based cohorts comprising 14,876 individuals.

Neurobiol Aging

February 2025

Department of Neurology, University Medical Center Utrecht Brain Center, Utrecht, the Netherlands; Department of Neurology, Diakonessenhuis Hospital, Utrecht, the Netherlands.

Article Synopsis
  • White matter hyperintensities (WMH) increase with age and vary significantly between individuals, prompting the need for age- and sex-specific data for better assessment.
  • This study pooled data from nearly 15,000 healthy individuals aged 18-97 to analyze WMH volumes using MRI and established centile curves based on age and sex.
  • Findings reveal that WMH volumes increase significantly with age, with females having larger volumes, and these changes follow different patterns based on specific white matter locations, providing valuable normative data for clinical interpretations.

Background: The use of antibiotic-loaded bone cements (ALBCs) in arthroplasty has been well established for the prevention and treatment of infections. Tigecycline (Tig), a broad-spectrum antibiotic, has shown efficacy against various pathogens, including vancomycin-resistant strains.

Method: ISO and DIN mechanical and microbiological inhibition zone tests were performed on PMMA cement with manually added Tigecycline.

Sacroiliac joint auricular surface morphology modulates its mechanical environment.

J Anat

November 2024

Division of Macroscopic and Clinical Anatomy, Gottfried Schatz Research Center, Medical University Graz, Graz, Austria.

The sacroiliac joint (SIJ) exhibits significant variation in auricular surface morphology. This variation influences the mechanics of the SIJ, a central node for transmitting mechanical energy from upper body to lower limbs and vice versa. The impact of the auricular surface morphology on stress and deformation in the SIJ remains poorly understood to date.

Article Synopsis
  • Cancer can lead to serious kidney issues in children requiring kidney replacement therapy (KRT), with a study identifying 287 pediatric KRT patients who had a history of cancer.
  • The study showed that those whose cancer caused KRT had a longer wait for kidney transplantation compared to matched controls, with a median time of 2.4 years for cancer patients versus shorter times for controls.
  • While childhood cancer survivors experienced increased mortality rates while on KRT (16% for group 1 and 23% for group 2) compared to controls, their long-term survival rates after kidney transplantation were similar to non-cancer patients.
