Abstract Background Coronary collateral circulation (CCC) provides an alternative blood flow to myocardial tissue exposed to ischemia and helps to preserve myocardial functions. Endothelial-derived nitric-oxide (NO) production and vascular endothelial growth factor (VEGF) have been suggested as the most important factors in the development of CCC. Adropin is a peptide hormone responsible for energy hemostasis, and is known for its positive effects on the endothelium through NO and VEGF. Objective The aim of this study is to investigate the association between adropin and the presence of CCC in patients with chronic coronary syndrome (CCS). Methods A total of 102 patients with CCS, who had complete occlusion of at least one major epicardial coronary artery, were included in the study and were divided into two groups: the group of patients (n:50) with poor CCC (Rentrop 0-1) and the group of patients (n:52) with good CCC (Rentrop 2-3). The level of significance adopted in the statistical analysis was 5%. Results Mean adropine levels were found as 210.83±17.76 pg/mL and 268.25±28.94 pg/mL in the poor and good CCC groups, respectively (p<0.001). Adropin levels proved to be positively correlated with neutrophil-to-lymphocyte ratios (r:0.17, p:0.04) and the rentrop scores (r:0.76, p<0.001), and negatively correlated with age (r:-0.23, p:0.01) and Gensini scores (r:-0.19, p:0.02). Adropin level is a strong independent predictor of good CCC development (OR:1.12, 95% CI:(1.06-1.18), p<0.001). Conclusion This study suggests that adropin levels may be a possible factor associated with the presence of CCC in CCS patients.
ABSTRACT
BACKGROUND: Coronary collateral circulation (CCC) provides an alternative blood flow to myocardial tissue exposed to ischemia and helps to preserve myocardial functions. Endothelial-derived nitric-oxide (NO) production and vascular endothelial growth factor (VEGF) have been suggested as the most important factors in the development of CCC. Adropin is a peptide hormone responsible for energy hemostasis, and is known for its positive effects on the endothelium through NO and VEGF. OBJECTIVE: The aim of this study is to investigate the association between adropin and the presence of CCC in patients with chronic coronary syndrome (CCS). METHODS: A total of 102 patients with CCS, who had complete occlusion of at least one major epicardial coronary artery, were included in the study and were divided into two groups: the group of patients (n:50) with poor CCC (Rentrop 0-1) and the group of patients (n:52) with good CCC (Rentrop 2-3). The level of significance adopted in the statistical analysis was 5%. RESULTS: Mean adropine levels were found as 210.83±17.76 pg/mL and 268.25±28.94 pg/mL in the poor and good CCC groups, respectively (p<0.001). Adropin levels proved to be positively correlated with neutrophil-to-lymphocyte ratios (r:0.17, p:0.04) and the rentrop scores (r:0.76, p<0.001), and negatively correlated with age (r:-0.23, p:0.01) and Gensini scores (r:-0.19, p:0.02).

The objective of this paper was to define the effect of education on the early diagnosis of breast and cervix cancer on the women's attitudes and behaviors regarding participating in Cancer Early Diagnosis, Screening and Training Centers-CEDSTC screening programs. This semi-experimental study was completed with 342 women. The data were collected with forms "Champion's Health Belief Model Scale Breast Cancer-HBMSBC" and "Health Belief Model Scale for Cervical Cancer and the Pap Smear Test-HBMSCCPST." When the women's health beliefs before and after 6 months of the education about the early diagnosis of breast and cervical cancers are considered, it is seen that the HBMSBC subscales health motivation, breast self-examination (BSE), and evasion to mammography (MMG) decreased and BSE self-efficacy and MMG benefit attitudes increased and HBMSCCPST subscales pap smear benefit attitudes increased and evasion to pap smear attitude decreased (p < 0.05). Six months after the education, 28.4% of the women had undergone MMG, 69.9% had performed BSE, and 33.6% had undergone a pap smear test. Education regarding early diagnosis of breast and cervix cancer was found to have positive effects on the health behaviors of the women related to BSE, MMG, and pap smear tests. The women require professional education program for increasing their attitudes and behaviors for CEDSTC screening programs. We suggest regularly providing education to increase participation in early screening programs.
