Background: Patients on peritoneal dialysis (PD) frequently have cognitive impairment, which is linked to a poor prognosis. The purpose of this study was to determine whether abdominal aortic calcification (AAC) may have an impact on PD patients' cognitive function.

Methods: In this cross-sectional study of 110 PD patients, cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), and AAC severity was quantified via lateral lumbar radiography (Kauppila method). Participants were stratified by AAC severity into high (HAAC; score ≥ 4) and low (LAAC; score < 4) groups.

Results: Cognitive impairment (MoCA < 26) was present in 65.45% of patients. The HAAC group (71.8% of cohort) exhibited distinct metabolic profiles compared to LAAC: older age (63.2 ± 9.8 vs. 47.4 ± 12.1 years, P < 0.001), higher diabetes prevalence (68.4% vs. 22.6%, P < 0.001), elevated serum phosphorus (1.62 ± 0.45 vs. 1.30 ± 0.42 mmol/L, P < 0.001), and lower diastolic blood pressure (79.2 ± 10.8 vs. 86.6 ± 13.4 mmHg, P = 0.005). Notably, HAAC patients had reduced serum creatinine (898.4 ± 251.9 vs. 1190.7 ± 243.5 µmol/L, P < 0.001) and iPTH levels (142.5 vs. 218.0 pg/mL, P = 0.011), suggesting concurrent mineral bone disorder. Multivariate analysis identified AAC severity (OR = 1.28 per 1-point increase, 95%CI = 1.09-1.50) and age (OR = 1.12/year, 95%CI = 1.06-1.19) as independent predictors of cognitive impairment.

Conclusion: AAC severity demonstrates a strong, dose-dependent association with cognitive dysfunction in PD patients, independent of traditional risk factors. The combination of elevated phosphorus and suppressed iPTH in high-AAC patients highlights the potential role of mineral metabolism dysregulation in both vascular calcification and neurocognitive decline.

The celiac ganglia are a network of nerve fibers that regulate various functions related to digestion, while the celiac trunk is a major artery that supplies oxygenated blood to the stomach, small intestine, and other organs in the upper abdominal region. Anatomical variants of these structures are common and can have significant implications for surgical and medical procedures. This prospective observational study was conducted over one year and included 300 patients (aged 45-75 years) with a history of peripheral arterial disease, evaluated at Dr.

Background: Peripheral artery disease (PAD) is a globally prevalent atherosclerotic disease associated with an increased risk of cardiovascular and cerebrovascular diseases and a poor prognosis. Skeletal muscle loss (sarcopenia) is particularly common in patients with PAD and is closely associated with poor prognosis.

Aims: The aim of this study was to evaluate the area, density and fat infiltration of skeletal muscle in patients with PAD by CT, and to analyze their relationship with the degree of vascular stenosis.

A 69-year-old male diagnosed with subacute myocardial infarction was subsequently transferred to our institution. Upon admission, echocardiography revealed ventricular septal rupture (VSR). The patient was promptly supported via venoarterial (VA) extracorporeal membrane oxygenation (ECMO) and Impella CP before surgical VSR repair on the 12th day of admission.
