Erythroferrone and hepcidin levels in children with iron deficiency anemia.

BACKGROUND: Iron deficiency anemia remains a significant public health issue in developing countries. The regulation of iron metabolism is primarily controlled by hepcidin, a key regulatory protein. During erythropoiesis, erythroferrone (ERFE), a hormone produced by erythroblasts in response to erythropoietin (EPO) synthesis, mediates the suppression of hepcidin. In this study, it was aimed to determine the correlation between erythroferrone (ERFE) and hepcidin levels in children with iron deficiency anemia. METHODS: This is a case-control study conducted at Kirsehir Ahi Evran University Training and Research Hospital Pediatrics Clinic between 1 and 31 September 2020. The study included 26 healthy children and 26 children with iron deficiency anemia. In order to evaluate iron status,whole blood count, serum iron, total iron binding capacity (TIBC), and ferritin levels were analyzed. The study measured the levels of hepcidin and erythroferrone in the serum of children diagnosed with iron deficiency before and after one month of iron treatment, as well as in a control group, using the ELISA method. Correlation between whole blood count, initial ferritin, hepcidin, ERFE and ferritin in the iron deficiency group was evaluated. RESULTS: Compared with healthy controls, the iron-deficient group had significantly lower haemoglobin (p < 0.001), MCV (p = 0.001), MCH (p < 0.001), MCHC (p < 0.001), iron (p < 0.001), ferritin (p < 0.001) and hepcidin (p = 0.001). Ferritin and hepcidin levels increased while erythroferrone levels remained unchanged after iron deficiency treatment. There was no correlation between hepcidin and ferritin levels in treatment group. CONCLUSIONS: The study found a strong and positive correlation between ferritin and hepcidin levels in iron-deficient children, but not between ERFE levels, suggesting that hepcidin is largely regulated by iron deposition levels. In addition, there was an increase in ferritin and hepcidin levels after iron treatment. The study found no significant difference in erythroferrone levels between the iron-deficient group and the control group. It is thought that this may be due to the short duration of iron treatment given to the patients with iron deficiency anemia included in the study.

The assessment of the knowledge and practices of healthcare providers regarding paroxysmal non-epileptic events (PNES) in children: A cross-sectional study.

OBJECTIVE: Paroxysmal non-epileptic events (PNEs) are a group of disorders that may be misdiagnosed as epilepsy. This study has aimed to assess the knowledge and practices of family physicians and pediatricians regarding the diagnosis, treatment, and follow-up of PNEs in children. METHODS: The study was designed as a prospective cross-sectional study that was conducted between March 1, 2022, and June 1, 2022, by reaching pediatric specialists and assistants, family physicians, subspecialty assistants, and subspecialists using a Google questionnaire. The survey consists of 26 questions. The questionnaire used by the researchers was prepared in accordance with the literature search and it included detailed questions on the diagnosis, treatment, and differential diagnosis of PNEs. RESULTS: A total of 37.3% worked as specialists. Most of the participants (41.3%) have worked in training and research hospitals, and 44.3% have been physicians for 6-10 years. The mean and standard deviation for the total score were 10.1 ± 2.6. The scores of family physicians were statistically lower than those of specialists, subspecialty assistants, and subspecialists. A total of 67.2% left the decision of whether the patient should stop taking their medication to another clinician. 45% of the doctors said that they were uncomfortable with the diagnosis. SIGNIFICANCE: The study findings emphasized the significant knowledge gap among healthcare providers regarding PNEs in children, highlighting the need for targeted educational interventions to improve their understanding and diagnostic skills in this area.

Knowledge and Attitudes of Physicians and Nurses in Turkey Regarding Human Papillomavirus Vaccination of Their Children.

AIM: This study aimed to determine the knowledge and attitudes of physicians and nurses as parents about human papillomavirus (HPV) vaccination and their views on vaccination in children. MATERIALS AND METHODS: This cross-sectional study included 72 physicians and 128 nurses who had children. Data were collected using questionnaires prepared by researchers. Descriptive statistical analysis and chi-square tests were used for data analysis. RESULTS: In this study, 84.7% of physicians and 70.3% of the nurses knew that HPV is a cancer factor, and two-thirds of the healthcare professionals believed that the HPV vaccine is protective. Moreover, 62.5% of physicians and 74.2% of nurses reported that they did not intend to vaccinate their children. The reasons for vaccination hesitancy of healthcare professionals was believing it was unnecessary, thinking it was expensive, having insufficient knowledge about vaccine, thinking it may have side effects, and not trusting the vaccine. In this sample, 70.8% of physicians and 53.9% of nurses stated that they could have their children vaccinated only if the HPV vaccines were in the national vaccination schedule. DISCUSSION: Further studies should be conducted to include the HPV vaccine in the childhood national vaccination program to reduce vaccine hesitancy.
