Article Abstract

Background: Pulse wave velocity (PWV) is considered a more direct and accurate measure of arterial stiffness. This study explored the relationship between PWV and the presence and severity of coronary artery calcification (CAC) and coronary artery plaque (CAP).

Methods: The current study was a cross-sectional analysis of data from the Miami Heart Study (MiHeart). The primary outcome variable of this study was the CAC score. The secondary outcome was the presence of CAC and CAP. Multivariable logistic regression and Bayesian linear regression were used to find the association between PWV CAC and CAP.

Results: A total of 2359 participants were included in the study. The mean age (SD) of the sample was 53.4 (6.8) years and 50.4% were men. Multivariable logistic regression analysis showed that the odds of having CAC greater than 0 was significantly higher with increasing PWV [odds ratio (OR): 1.09, 95% confidence interval (CI): 1.01-1.18]. Similarly, multivariable logistic regression analysis also showed that the odds for CAP were significantly higher with increasing PWV (OR: 1.14, 95% CI: 1.06-1.23). The results of Bayesian linear regression analysis showed that there was a significant association between PWV and log CAC score.

Conclusion: In a large sample of participants from the community and without a history of known cardiovascular disorder, we found that an increase in PWV was associated with the presence of CAC and CAP. In addition, we also found that PWV was associated with severity of CAC as well. Our findings show that PWV could be an important marker of subclinical coronary atherosclerosis in the general population.

Syringomyelia is a common and heritable disorder in Cavalier King Charles Spaniels (CKCS), characterised by fluid accumulation within the spinal cord that may result in pain and neurological dysfunction. The prevalence of syringomyelia in CKCS in Australia has not previously been reported. The goal of this study was to assess the prevalence and severity of syringomyelia in magnetic resonance imaging (MRI)-screened breeding CKCS in New South Wales, Australia, from 2008 to 2024, and to evaluate changes over time.

Background: Lung cancer (LC) is the leading cause of cancer-related deaths globally. Genetic variants in mismatch repair (MMR) genes, such as MutS homolog 2 (MSH2), MutS homolog 6 (MSH6) and MutL homolog 1 (MLH1), may influence individual susceptibility and clinical outcomes in LC.

Objective: This study investigated the associations of genetic polymorphisms in MSH2, MSH6, and MLH1 with susceptibility and survival outcomes in lung cancer patients in the Guangxi Zhuang population.

Objective: To develop a novel prognostic scoring system for severe cytokine release syndrome (CRS) in patients with B-cell acute lymphoblastic leukemia (B-ALL) treated with anti-CD19 chimeric antigen receptor (CAR)-T-cell therapy, aiming to optimize risk mitigation strategies and improve clinical management.

Methods: This single-center retrospective cohort study included 125 B-ALL patients who received anti-CD19 CAR-T-cell therapy from January 2017 to October 2023. These cases were selected from a cohort of over 500 treated patients on the basis of the availability of comprehensive baseline data, documented CRS grading, and at least 3 months of follow-up.

September 2025

Department of Neurology, Xiangya Hospital, Central South University, No.87 Xiangya Road, Kaifu District, Changsha, 410008, Hunan Province, China.

Background And Objective: Differentiating central nervous system infections (CNSIs) from brain tumors (BTs) is difficult due to overlapping features and the limited individual indicators, and cerebrospinal fluid (CSF) cytology remains underutilized. To improve differential diagnosis, we developed a model based on 9 early, cost-effective cerebrospinal fluid parameters, including CSF cytology.

Methods: Patients diagnosed with CNSIs or BTs at Xiangya Hospital of Central South University between October 1st, 2017 and March 31st, 2024 were enrolled and divided into the training set and the test set.

Background: The optimal number of examined lymph nodes (ELN) for accurate staging and prognosis for esophageal cancer patients receiving neoadjuvant therapy remains controversial. This study aimed to evaluate the impact of ELN count on pathologic staging and survival outcomes and to develop a predictive model for lymph node positivity in this patient population.

Methods: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database and a multicenter cohort.
