Background: Tuberculosis is a chronic recurrent infection and inflammation is part of the disease which may remain undiagnosed for months. Furthermore immunization with recombinant heat shock protein-65-rich mycobacterium tuberculosis increased atherogenesis in hypercholesterolemic animal models.
Objective: To investigate the potential interrelationships between past tuberculosis with carotid and femoral atherosclerosis in hypercholesterolemic patients.
Design And Setting: Case control study in a university hospital.
Patients: Two groups of hypercholesterolemic patient group (n=147) studied in a cardiovascular prevention unit during the same quarter, age (+/-1 year) and sex-matched. The first group presented a history of tuberculosis in the past and the second group never.
Methods: Atherosclerosis was assessed by carotid and femoral external echography. Measurements of maximum plaque diameter were done in longitudinal planes, and the extent of atherosclerosis was graded according to the most severe visible changes on the scanned arteries.
Results: The frequency and the distribution of atherosclerosis was similar in the two groups, whatever the arterial site explored, carotid or femoral. None of the clinical and biological studied variables were different between the two groups of patients.
Conclusion: Past tuberculosis is not associated with increased frequency of atherosclerotic lesions in hypercholesterolemic patients.

Background: Patients with solitary functioning kidney appear to be exposed to an increased cardiovascular risk. This study aimed to evaluate the impact of peripheral and central blood pressure on subclinical cardiovascular organ damage in a sample of children and adolescents with solitary functioning kidney.
Methods: Carotid ultrasonography was performed to measure the carotid intima-media thickness (cIMT) and the carotid distensibility coefficient.

Transcarotid artery revascularization (TCAR) is a novel method to treat severe stenosis of the carotid artery with minimal embolization. During TCAR, flow reversal system redirects blood from the internal, external, and common carotid arteries into the femoral vein through a filter system to prevent debris and microparticles from entering the cerebral circulation. Transcranial Doppler (TCD) monitoring allows real-time detection of blood flow in the cerebral arteries during the operation and informs the surgeon of flow changes or possible emboli.

Arterial stiffness, as determined by pulse wave velocity (PWV), is a recognized marker of cardiovascular risk. Noninvasive technologies have enabled easier and more accessible assessments of PWV. The current gold standard for measuring carotid-femoral PWV (cfPWV)-a reliable indicator of arterial stiffness-utilizes applanation tonometry devices, as recommended by the Artery Society Guidelines.

Trimethylamine -oxide (TMAO), a gut microbiome-derived metabolite, participates in the atherogenesis and vascular stiffening that is closely linked with cardiovascular (CV) complications and related deaths in individuals with kidney failure undergoing peritoneal dialysis (PD) therapy. In these patients, arterial stiffness (AS) is also an indicator of adverse CV outcomes. This study assessed the correlation between serum TMAO concentration quantified with high-performance liquid chromatography and mass spectrometry and central AS measured by carotid-femoral pulse wave velocity (cfPWV) in patients with chronic PD.

Purpose: The dietary egg-protein hydrolysate Newtricious (NWT)-03 has previously demonstrated improvements in blood pressure and metabolic profiles. However, the long-term effects on vascular function and cardiometabolic risk markers are unknown.
Methods: Forty-four older (aged 60-75) adults with overweight/obesity experiencing elevated Subjective Cognitive Failures (SCF) were randomized into a 36-week, double-blind, placebo-controlled trial.
