Medication Adherence and Health Literacy in Patients with Heart Failure: A Cross-Sectional Survey in Iran.

Background: Heart failure is a costly condition with high morbidity and mortality rates in low- and middle-income countries. Nonadherence to prescribed therapies can lead to severe problems such as poorer health outcomes, higher health care expenditures, increased hospitalizations, and even higher mortality rates in patients with advanced heart disease.

Objective: The aim of the present study is to investigate medication adherence and the association between medication adherence and health literacy in Iranian patients with heart failure.

CT-measured pulmonary artery diameter as an independent predictor of pulmonary hypertension in cystic fibrosis.

Purpose: The role of computed tomography (CT) scan, as a promising prognostic imaging modality in cystic fibrosis (CF), has been widely investigated, focusing on parenchymal abnormalities. The aim of the present study was to evaluate the diagnostic performance of thoracic vascular parameters on CT to detect pulmonary hypertension (PH).

Material And Methods: CF patients who contemporaneously underwent CT and echocardiography were retrospectively enrolled.

Significant effects of 4-aminopyridine and tetraethylammonium in the treatment of 6-hydroxydopamine-induced Parkinson's disease.

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterizing by degeneration of dopaminergic neurons in the nigrostriatal pathway. The discovery of levodopa revolutionized the treatment of PD however, after several years of treatment most patients develop involuntary movements which significantly impair the quality of life. 4-Aminopyridine (4-AP) and tetraethylammonium (TEA) are wide-spectrum potassium channel blockers which based on the animal model studies and clinical trials have beneficial effects in treatment of several neurological disorders such as ataxia, Alzheimer disease and multiple sclerosis.
