Effectiveness of the ECG method in the correct positioning of PICC type central venous catheters in patients with atrial fibrillation.

The peripherally inserted central catheters (PICCs) are third generation silicone or polyurethane catheters, used as venous accesses for long- and medium-term care, and recommended in therapies that require venous access for more than six days. Current implantation methods recommend the radiological method, using standard chest RX in antero-posterior projection, as a method of assessing the correct positioning of the catheter tip. The observational study evaluated the effectiveness in terms of reliability of the intracavitary tip location system (ITLS) method, better known as the ECG method, for the correct positioning of the catheter tip in patients with atrial fibrillation (AFIB); the method exploits the recording of the electrical potential produced by the f waves, expression of the fibrillation of the atrium typical in patients with this disease, the measurement is based on the calculation of the peak-to-peak value of the f waves.

Associations between low levels of serum uric acid and cardiometabolic parameters.

Introduction: Elevated serum uric acid (SUA) levels are associated with increased cardiovascular risk.

Objective: To evaluate the association between SUA levels and cardiometabolic parameters.

Materials And Methods: SUA levels and metabolic parameters were evaluated in 139 subjects, divided into low (<5 mg/dl) and high SUA group (≥5 mg/dl).

Serum uric acid levels and metabolic syndrome.

Objective: To investigate the relationship among serum uric acid levels and metabolic syndrome.

Materials And Methods: Anthropometric parameters, serum uric acid and metabolic parameters were evaluated in 139 subjects.

Results: Serum uric acid levels were significantly higher in subjects with than without metabolic syndrome (p < 0.
