Background: Previous studies utilizing dual-energy CT (DECT) for evaluating treatment efficacy in nasopharyngeal cancinoma (NPC) are limited. This study aimed to investigate whether the parameters from DECT can predict the response to induction chemotherapy in NPC patients in two centers.

Methods: This two-center retrospective study included patients diagnosed with NPC who underwent contrast-enhanced DECT between March 2019 and November 2023.

Acute myeloid leukemia (AML) is caused by altered maturation and differentiation of myeloid blasts, as well as transcriptional/epigenetic alterations, all leading to excessive proliferation of malignant blood cells in the bone marrow. Tumor heterogeneity due to the acquisition of new somatic alterations leads to a high rate of resistance to current therapies or reduces the efficacy of hematopoietic stem cell transplantation (HSCT), thus increasing the risk of relapse and mortality. Single-cell RNA sequencing (scRNA-seq) will enable the classification of AML and guide treatment approaches by profiling patients with different facets of the same disease, stratifying risk, and identifying new potential therapeutic targets at the time of diagnosis or after treatment.

Due to its enormous influence on system functionality, researchers are presently looking into the issue of task scheduling on multiprocessors. Establishing the most advantageous schedules is often regarded as a difficult-to-compute issue. Genetic Algorithm is a recent tool employed by researchers to optimize scheduling tasks and boost performance, although this field of research is yet mostly unexplored.

Background/purpose: Taste impairment is a common yet complex toxicity of head and neck cancer (HNC) radiotherapy treatment that may affect quality of life of survivors. This study aimed to predict acute and late taste impairment using taste bud bearing tongue mucosa as a new taste-specific organ-at-risk compared to full oral cavity as identified in previous studies.

Materials/methods: Included HNC patients were treated with curative radiotherapy between 2007 and 2022.

Radiation exposure in neurosurgical intensive care unit patients: Balancing diagnostic benefits and long-term risks.

Life Sci

January 2025

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.
