Introduction: Animal models have been used to understand the pathophysiology of pulmonary hypertension, to describe the mechanisms of action and to evaluate promising active ingredients. The monocrotaline-induced pulmonary hypertension model is the most used animal model. In this model, invasive and non-invasive hemodynamic variables that resemble human measurements have been used. Aim: To define if non-invasive variables can predict hemodynamic measures in the monocrotaline-induced pulmonary hypertension model. Materials and Methods: Twenty 6-week old male Wistar rats weighing between 250-300g from the bioterium of the Universidad del Valle (Cali - Colombia) were used in order to establish that the relationships between invasive and non-invasive variables are sustained in different conditions (healthy, hypertrophy and treated). The animals were organized into three groups, a control group who was given 0.9% saline solution subcutaneously (sc), a group with pulmonary hypertension induced with a single subcutaneous dose of Monocrotaline 30 mg/kg, and a group with pulmonary hypertension with 30 mg/kg of monocrotaline treated with Sildenafil. Right ventricle ejection fraction, heart rate, right ventricle systolic pressure and the extent of hypertrophy were measured. The functional relation between any two variables was evaluated by the Pearson correlation coefficient. Results: It was found that all correlations were statistically significant (p <0.01). The strongest correlation was the inverse one between the RVEF and the Fulton index (r = -0.82). The Fulton index also had a strong correlation with the RVSP (r = 0.79). The Pearson correlation coefficient between the RVEF and the RVSP was -0.81, meaning that the higher the systolic pressure in the right ventricle, the lower the ejection fraction value. Heart rate was significantly correlated to the other three variables studied, although with relatively low correlation. Conclusion: The correlations obtained in this study indicate that the parameters evaluated in the research related to experimental pulmonary hypertension correlate adequately and that the measurements that are currently made are adequate and consistent with each other, that is, they have good predictive capacity.

Background: Diabetes is a global epidemic with serious complication and there is a clear need for paying special attention to self-management as the cornerstone to optimal control of the disease. Objectives: This study aimed to assess the self-management status and its correlation to disease control indicators in people with diabetes. Methods: In a descriptive cross-sectional study, 220 patients were selected from the list of the referred patients available in Lamerd public health network from December 2014 to June 2015. In the first step, data about demographic information and disease control were collected from the patients’ records. In the second step, the self-management status of each patient was assessed by the Diabetes Self-Management Questionnaire developed by Schmitt et al. To analyze the data, independent sample t-test and Pearson correlation coefficient were used. Results: The mean age of the male and female participants was 56.43 ± 13.50 and 56.46 ± 10.49 years old, respectively. The mean duration of the disease was 6.67 ± 4.72 years for men and 7.07 ± 5.30 years for women. Twenty-one (25.9%) men and 60 (43.7%) women had a history of smoking. The results of the Pearson correlation coefficient showed that there was an inverse and statistically significant relationship between diabetes self-management status and weight, body mass index (BMI), waist circumference, glucose tolerance test (GTT), LDL, and cholesterol. The results of the t-test did not show significant differences between the level of HbA1C (HbA1C7) and self-management scores of the patients (P > 0.05). Conclusions: Patients with better self-management status were in a better disease control condition with respect to weight, BMI, waist circumference, GTT, LDL, and cholesterol levels. Special attention to the control and management of LDL, cholesterol, HbA1C, BMI, and blood pressure levels is recommended in planning for these patients.
