Symptom Burden and Dietary Changes Among Older Adults with Cancer: A Cross-Sectional Study.

Curr Oncol

December 2024

Department of Hematology and Medical Oncology, University Medical School, Robert-Koch-Straße 40, 37075 Göttingen, Germany.

Background: Malnutrition has a direct impact on both the toxicities of cancer therapy and the overall survival of oncological patients. However, its prevalence amongst vulnerable groups such as older patients (age ≥ 65 years) is often underestimated. Screening tools recognizing patients at risk are well established, yet they do not take into account that cancer therapy may lead to changes in dietary habits or that therapy's side effects may negatively influence nutritional status.

Rapid non-invasive measurement of mitochondrial oxygen tension after microneedle pre-treatment: a feasibility study in human volunteers.

J Clin Monit Comput

December 2024

Department of Critical Care, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.

Mitochondrial oxygen tension (MitoPO2) is a promising novel non-invasive bedside marker of circulatory shock and is associated with organ failure. The measurement of mitoPO2 requires the topical application of 5-aminolevulinc acid (ALA) to induce sufficient concentrations of the fluorescent protein protoporphyrin-IX within (epi)dermal cells. Currently, its clinical potential in guiding resuscitation therapies is limited by the long induction time prior to obtaining a reliable measurement signal.

Chronic pelvic insufficiency fractures and their treatment.

Arch Orthop Trauma Surg

December 2024

Department of Orthopaedic Surgery and Traumatology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland.

Article Synopsis
  • Fragility and insufficiency fractures of the pelvis and sacrum are on the rise among the elderly due to weakened bones, leading to persistent pain, reduced mobility, and a risk of loss of independence.
  • While conservative treatments are an option, surgery is often preferred for unstable fractures, especially since many patients do not receive adequate preventative care for osteoporosis-related fractures.
  • Diagnostic imaging is crucial for identifying these fractures, with CT scans being the gold standard, but MRI offers the highest sensitivity for detecting complex fractures, guiding treatment based on fracture type and stability.

Electronic address:

Medical image analysis has significantly benefited from advancements in deep learning, particularly in the application of Generative Adversarial Networks (GANs) for generating realistic and diverse images that can augment training datasets. The common GAN-based approach is to generate entire image volumes, rather than the region of interest (ROI). Research on deep learning-based brain tumor classification using MRI has shown that it is easier to classify the tumor ROIs compared to the entire image volumes.
