Assessment the effect of diabetes education on self-care behaviors and glycemic control in the Turkey Nursing Diabetes Education Evaluating Project (TURNUDEP): a multi-center study
Background: Diabetes education in Turkey is provided by diabetes nurse educators in almost all healthcare organizations. However, the education is not standardized in terms of learning content, duration, and methods. This multi-center study was performed to assess the self-care behaviors and glycemic control following education provided to the patients with type 2 diabetes mellitus by diabetes nurse educators. Methods: This was a descriptive and cross-sectional study and included 1535 patients admitted to 28 public hospitals for the treatment of type 2 diabetes mellitus. The education was assessed by using a Patient Identification Form and Self-care Scale. Results: The proportion of individuals who received diabetes education within the last year was 78.5%, with 46.7% of them having received it once. Of the patients, 84.8% reported that they received diabetes education individually. It was found that the proportion of individuals who received education about oral antidiabetics (78.5%) and glucose testing at home (78.5%) was higher than the proportion of individuals who received education about exercise (58.8%) and foot care (61.6%). The status of diabetes education, education intervals, and the correlation of the education method with self-care and glycemic control was evaluated. Self-care and glycemic control levels were better among the patients who received diabetes education thrice or more and in patients who received education both individually and in a group (p < 0.05). Conclusions: Approximately three-quarters of individuals with type 2 diabetes mellitus received education by diabetes nurse educators in Turkey. Diabetes education is positively correlated with self-care and glycemic control levels among patients with type 2 diabetes mellitus. Efforts for generalization and standardized education for all diabetes patients are necessary. © 2022, The Author(s)
Marriage honey bee optimization approach to the symmetric traveling salesman problem
WOS:000304504700004Marriage Honey Bee Optimization (MBO) is one of Swarm intelligence methods that is used to solve complicated problems. MBO is a meta-heuristic method that was inspired and developed from honey bee mating and fertilization processes. The aims of Traveling Salesman Problem (TSP) is find the shortest and cheapest route pass from each city ones and returning to the starting city. TSP which underlies many real-life problems is widely used to obtain effective solutions for large-scale problems. In this study, the MBO algorithm was applied to solve the symmetric TSP that was solved by different methods previously. The results of recommended MBO algorithm for TSP were compared with other meta-heuristic approaches

A marriage in honey bee Ooptimisation approach to the asymmetric Travelling salesman problem
WOS:000305161100018In the travelling salesman problem (TSP), a travelling salesman completes a tour of "n" number of cities by stopping once in each city and completes the tour by returning to his starting point, while minimizing the distance and the cost. The asymmetric travelling salesman problem (ATSP) is the problem in which the cost of travel from city A to B is different from that from B to A. Marriage in Honey Bee Optimisation (MBO) is a meta-heuristic procedure inspired by the mating and insemination process of honey bees. In this study, we seek to use an MBO algorithm for an optimal solution to the ATSP problem, which has previously been solved by different methods. The results of the MBO algorithm for ATSP are compared with Genetic Algorithm (GA), another meta-heuristic method
Retinopathy of Prematurity in Triplets
Objectives: To investigate the incidence, severity and risk factors of retinopathy of prematurity (ROP) in triplets.
Materials and Methods: The medical records of consecutive premature triplets who had been screened for ROP in a single maternity
hospital were analyzed and presence and severity of ROP; birth weight, gender, gestational age of the infant; route of delivery and the
mode of conception were recorded.
Results: A total of 54 triplets (40 males, 14 females) who were screened for ROP between March 2010 and February 2013 were recruited
for the study. All triplets were delivered by Caesarean section and 36 (66.7%) were born following an assisted conception. During
follow-up, seven (13%) of the infants developed ROP of any stage and two (3.7%) required laser photocoagulation. The mean gestational
age of triplets with ROP was 27.6±1.5 (27-31) weeks whereas it was 32.0±1.5 (30-34) weeks in those without ROP (p=0.002). The
mean birth weights of triplets with and without ROP were 1290.0±295.2 (970-1600) g and 1667.5±222.2 (1130-1960) g, respectively
(p<0.001). The presence of ROP was not associated with gender (p=0.358) or mode of conception (p=0.674).
Conclusion: ROP in triplets seems to be mainly related to low gestational age and low birth weight. Further prospective randomized
studies are necessary to demonstrate risk factors of ROP in triplets and to determine if and how gemelarity plays a role in the development
of ROP

Is there any possibility of uterine sarcoma, STUMP and benign myoma variants in the patients operated for myoma uteri
Malignant pathologies may be observed in the histopathological examination of the patients who were operated with the diagnosis of myoma uteri. We aimed to investigate the rates of detection of uterine sarcoma, smooth muscle tumor of uncertain malignant potential and benign myoma variants who were operated due to myoma uteri. Patients who were operated with the diagnosis of myoma uteri between 2012-2018 were included. Patients with and without malignant pathology were compared in terms of their characteristics. The malignancy was encountered in 39 patients (1.5%) among 2583 patients. A significant difference was found between the patients with and without malignancy in terms of age, admission complaints, and cervical smear results. Patients in the malignant group were found to be older (52.5±11.0 vs 48.1±6.1, p=0.016). Postmenopausal bleeding was significantly a more common complaint in the malignant group (p=0.028). The rate of abnormal cytology in the cervical smear results in the malignant group was 5.1% (p=0.004). Pathology reports of the patients who were operated for myoma uteri may result with malignancy. In the preoperative evaluation, it is necessary to pay attention to the patients' characteristics, to evaluate the risk factors for the possibility of a malignancy. © 2021 Ondokuz Mayis Universitesi
