Leucocyte telomere length (LTL) has been reported to be linked to ageing, cancer and cardiovascular disease (CVD). This study aimed to explore the association between LTL and CVD risk in a nationally representative sample of U.S. adults. Complex associations, including nonlinearity and interaction, were also examined. A total of 7,378 subjects from the National Health and Nutrition Examination Survey (NHANES) 1999-2002 were collected. Telomere length was detected from DNA samples and expressed as the mean T/S ratio (telomere repeats per single-copy gene). We performed multiple logistic regression models and interactive analysis to explore the associations between LTL and CVD risk by adjusting for potential confounders. We also performed a sensitivity analysis to investigate the robustness of our results. Among all participants, LTL was associated with the risk of CVD (OR = 0.79, 95% CI: 0.63~0.98, P = 0.033) in a linear manner rather than in a nonlinear manner (P = 0.874). Interaction effects of LTL with both education (P = 0.017) and hypertension (P = 0.007) were observed. Furthermore, using subgroup analyses, protective effects of LTL on CVD risk were found in females and in individuals who were college graduates or above, had serum cotinine >10 ng/ml, did not have hypertension, or had normal white blood cell levels. LTL is linearly inversely associated with CVD risk in the general population of the United States.

MicroRNAs (miRNAs) are short and non-coding RNAs binding to 3'UTR of target mRNAs to downregulate their expression. Recent studies have shown that miRNAs indirectly regulated alternative splicing (AS) by targeting splicing factors and caused shifts in splicing patterns of target genes. However, the roles of miRNA-regulating splicing factors in pancreatic cancer progression remain unknown. Herein, we reported that miR-193a-5p was markedly upregulated in pancreatic cancer tissues and cells and correlated with clinical outcomes of pancreatic cancer patients. Overexpression of miR-193a-5p contributed to the metastasis of pancreatic cancer cells both  and . The mechanistic investigation suggested that miR-193a-5p modulated oxoglutarate dehydrogenase-like (OGDHL) and extracellular matrix protein 1 (ECM1) AS by targeting serine/arginine-rich splicing factor 6 (SRSF6), leading to the activation of the epithelial-to-mesenchymal transition (EMT) process. Together, our findings highlighted the role of miR-193a-5p-targeting SRSF6 in pancreatic cancer metastasis, which may serve as a novel target for pancreatic cancer diagnosis and therapy.

miR-193a-5p promotes pancreatic cancer cell metastasis through SRSF6-mediated alternative splicing of OGDHL and ECM1.

Coarctation of the aorta (CoA), presenting with local stenosis of the aorta is involved in many cardiovascular processes. However, there has been little research on the mechanism of coarctation of the aorta.

Identified plasma proteins related to vascular structure are associated with coarctation of the aorta in children.

In children with tetralogy of Fallot (TOF), there is a risk of brain injury even if intracardiac deformities are corrected. This population follow-up study aimed to identify the correlation between cerebral morphology changes and cognition in postoperative school-aged children with TOF. Resting-state functional magnetic resonance imaging (rs-fMRI) and the Wechsler Intelligence Scale for Children-Chinese revised edition (WISC-CR) were used to assess the difference between children with TOF and healthy children (HCs). Multiple linear regression showed that the TOF group had a lower verbal intelligence quotient (VIQ, 95.000 ± 13.433,  = 0.001) than the HC group and that VIQ had significant positive correlations with the cortical thickness of both the left precuneus ( < 0.05) and the right caudal middle frontal gyrus ( < 0.05) after adjustment for preoperative SpO2, preoperative systolic blood pressure (SBP), preoperative diastolic blood pressure (DBP) and time of aortic override (AO). Our results suggested that brain injury induced by TOF would exert lasting effects on cortical and cognitive development at least to school age. This study provides direct evidence of the relationship between cortical thickness and VIQ and of the need for strengthened verbal training in school-aged TOF patients after corrective surgery.
