In order to check developed software tools, it was necessary to compare estimates of statistical characteristics of annual absorbed plutonium internal doses obtained by PANDORA and IMBA software with the same original data. The results were compared from dose calculations of five cases with different initial data on plutonium inhalation intake, lifetime measurements of plutonium activity in daily urine and post-mortem measurements in lungs, lung lymph nodes, liver and skeleton. Estimates of geometric mean and geometric standard deviation of annual regionally weighted lung dose and bone surface dose were compared. Satisfactory agreements of the estimates of statistical characteristics of annual doses to two critical organs for the selected cases were shown. One hundred individual hyper-realizations (forward model evaluations) are sufficient to calculate MWDS-2013 if only measurements of plutonium activity in daily urine are used, and 2000 individual hyper-realizations if both urine and autopsy measurement results are used.

Association of pre- and post-diagnosis dietary total antioxidant capacity (TAC) and composite dietary antioxidant index (CDAI) with overall survival in patients with ovarian cancer: a prospective cohort study.
J Transl Med

Department of Clinical Epidemiology, Shengjing Hospital of China Medical University, Shenyang, China.
Background: The evidence on the relationship of dietary antioxidant nutrients with the survival of ovarian cancer (OC) remains scarce.
Objective: This study aimed to investigate these associations in a prospective cohort of Chinese patients with OC.
Methods: In this prospective cohort study, patients with epithelial OC completed a food frequency questionnaire at diagnosis and 12 months post-diagnosis, and were followed from 2015 to 2023.
Pediatric obesity and the risk of multiple sclerosis: a nationwide prospective cohort study.

Division of Pediatrics, Department of Clinical Science, Intervention and Technology, Karolinska Institutet, S-141 57, Huddinge, Sweden.
Background: Emerging evidence implies a link between high pediatric body mass index (BMI) and an increased risk of multiple sclerosis (MS). However, previous research suggests this association is only present for adolescent obesity and not childhood obesity. The present study aimed to assess the association between pediatric obesity and risk of developing MS, and to investigate if degree of obesity and age at obesity treatment initiation affects the risk.

Transrectal shear wave elastography (T-SWE) can be used non-invasively to diagnose prostate cancer (PCa) and benign prostatic hyperplasia (BPH). The prostate tissue can be viewed as an ellipsoidal sphere with viscoelastic characterization. Linear elastic model has been used to characterize soft tissues, and the simplification of partial characterization provides incomplete information.

Background: Utilization of the emergency department (ED) is associated with medical and social comorbidities. These factors may also be associated with medical complications after complex surgeries. This study investigated how pre-operative ED use increases risk of posterior lumbar interbody fusion (PLIF) complications.

Department of Neurosurgery, Philipps University of Marburg, Baldingerstraße, 35033 Marburg, Germany; Center for Mind, Brain and Behavior (CMBB), 35043 Marburg, Germany.
Background: X-ray, computed tomography (CT), and digital subtraction angiography (DSA) techniques are indispensable in managing critically ill neurosurgical patients. However, repeated diagnostic imaging leads to cumulative radiation exposure, raising concerns about long-term risks such as malignancies. This study evaluates the frequency, dosage, and implications of radiation exposure in a neurosurgical intensive care unit (NICU) patient cohort.
