Is There a Need for Vitamin D Supplements During Summer Time in Northern Germany? A Study of Hospitalised Fracture Patients.

Background/objectives: Vitamin D is a key factor in bone metabolism, especially in patients who have suffered fractures, a group in need of a healthy bone metabolism. In Germany, a 70-year-old person requires 20 min of sun exposure daily for sufficient endogenous production in April. While this appears to be a sufficient period on paper, it raises the question of whether sufficient synthesis is achieved, given the time and the implementation of skin cancer prevention.

Pancreatic Adenocarcinoma: Long-Term Outcomes of Adjuvant Therapy in the ESPAC4 Phase III Trial.

Purpose: The ESPAC4 trial showed that adjuvant chemotherapy with gemcitabine plus capecitabine (GemCap) produced longer overall survival (OS) than gemcitabine monotherapy. Subsequently, the PRODIGE24-CCTG PA.6 trial showed even longer survival for modified fluorouracil, folinic acid, irinotecan, and oxaliplatin (mFOLFIRINOX) than gemcitabine but had more restrictive eligibility criteria.

Biomechanical Analysis of Diffuse Idiopathic Skeletal Hyperostosis and Osteoporosis: Vertebral Fracture Risk Evaluation Using Finite Element Modeling with Clinical and Micro-CT Data in an Elderly Donor.

Biomechanical analysis of spinal structures is crucial in the evaluation of injuries, the risk of fracture, and age-related changes. Osteoporotic vertebrae are very fragile and therefore constitute a serious risk, especially in the elderly. At present, clinically relevant decision making in fracture risk assessment is predicated upon finite element analysis (FEA), which utilizes high-resolution computed tomography (CT) scans from clinical practice alongside micro-CT scans from laboratory settings.
