Longitudinal CT Radiomics to Predict Progression-free Survival in Patients with Locally Advanced Gastric Cancer After Neoadjuvant Chemotherapy.
Acad Radiol
December 2024
Department of Radiology, The Affiliated Hospital of Qingdao University, Qingdao, Shandong Province, China (B.W., X.H., Z.Z., Z.L., S.L.). Electronic address:
Rationale And Objectives: To develop and validate a radiomics signature, utilizing baseline and restaging CT, for preoperatively predicting progression-free survival (PFS) after neoadjuvant chemotherapy (NAC) in locally advanced gastric cancer (LAGC).
Methods: A total of 316 patients with LAGC who received NAC followed by gastrectomy were retrospectively included in this single-center study; these patients were split into two cohorts, one for training (n = 243) and the other for validation (n = 73), based on the different districts of our hospital. A total of 1316 radiomics features were extracted from the volume of interest of the gastric-cancer lesion on venous phase CT images.
[F]FDG PET/CT Beyond Staging: Prognostic Significance of Sarcopenia and Adipose Tissue Metabolism in Esophageal Carcinoma.
Rev Esp Med Nucl Imagen Mol (Engl Ed)
December 2024
Department of Radiology, University of Health Sciences, Prof. Dr. Cemil Tascioglu City Hospital, Istanbul, Turkey.
Aim: This study aimed to investigate the relationship between PET and CT parameters and sarcopenia, adipose tissue, and tumor metabolism in esophageal carcinoma(EC) and its impact on survival in EC.
Method: Our study included 122 EC patients who underwent PET/CT for staging. Muscle and adipose tissue characteristics were evaluated, including lumbar(L3) and cervical(C3) muscle areas, psoas major(PM) and sternocleidomastoid muscle(SCM) parameters, and PET parameters for visceral and subcutaneous adipose tissue(SAT).
Regulatory T cell therapy is associated with distinct immune regulatory lymphocytic infiltrates in kidney transplants.

Nuffield Department of Surgical Sciences, University of Oxford, Oxford OX3 9DU, UK. Electronic address:
Background: Adoptive transfer of autologous regulatory T cells (Tregs) is a promising therapeutic strategy aimed at enabling immunosuppression minimization following kidney transplantation. In our phase 1 clinical trial of Treg therapy in living donor renal transplantation, the ONE Study (ClinicalTrials.gov: NCT02129881), we observed focal lymphocytic infiltrates in protocol kidney transplant biopsies that are not regularly seen in biopsies of patients receiving standard immunosuppression.

December 2024
Department of Epilepsy, Movement Disorders and Physiology, Graduate School of Medicine, Kyoto University, Kyoto, Japan. Electronic address:
Objective: Seizure suppression using the neurofeedback (NFB) method by self-regulation of scalp-recorded slow cortical potential (SCP) is effective for patients with refractory focal epilepsy. However, the prolonged training period required prevents it from wider implementation as the standard treatment in clinical practice. Therefore, we examined whether it would be appropriate to shorten the training period, in spite of the small number of patients.

Department of Internal medicine, Hawassa University Comprehensive Specialized Hospital, Hawassa, Sidama, Ethiopia.
Introduction And Importance: Chordoma is an uncommon malignant tumor that originates from the remnants of the primitive notochord in the embryo. They account for 1 % of intracranial tumors and 4 % of primary bone tumors. It is a locally aggressive tumor with a low risk of metastasis.
