    Topical Intranasal Insulin Enhances Healing of Nasal Mucosa: an Experimental Animal Study
    (Sage Publications inc, 2023) Kulekci, Cagri; Ozer, Serdar; Onen, Selin; Korkusuz, Petek; Yilmaz, Taner
    Objective Aim of this study was to evaluate the effect of topical intranasal insulin on healing of nasal mucosa in a rat model. Methods Forty-eight Wistar rats, weighing between 250 and 300 g and aged 10-12 weeks were used and randomized into two equal groups. 1.9 mm curette was introduced through the left nostril and 1.9 mm mucosa from the left nasal septum was curetted. Postoperatively, animals in the control group received 1 mL of physiologic saline, 3 times a day in a nasal irrigation fashion. Animals in the experimental group received 1 mL of 5 IU/mL regular insulin in saline solution. Subjects were sacrificed after 5, 10, and 15 days and macroscopic and histomorphometric evaluations were performed. Results There were no mucosal synechiae and septal perforation macroscopically. Histological examination revealed that the defect size reduction was 21% in the saline group versus 56% in the insulin group on the fifth day (p = 0.006). There was 62% defect reduction in the saline group versus 79% in the insulin group on the 10th day (p = 0.034). On the 15th day, only 67% of saline group animals had complete defect closure, whereas 100% of animals treated with insulin had complete closure (92% vs 100% mucosal defect reduction, p = 0.036). Both edema and inflammation were less in the insulin group on 15th day (p = 0.006; p = 0.023, respectively). Conclusion The results from this study support the safety and efficacy of topical insulin on wound healing in the literature. This study could guide further experimental studies that examine human sinonasal wound healing.

    Adult Education as a Stepping-Stone To Better Jobs: an Analysis of the Adult Education Survey in Turkey
    (Sage Publications inc, 2018) Cilasun, Seyit Mumin; Demir-Seker, Sirma; Dincer, N. Nergiz; Tekin-Koru, Ayca
    The objective of this article is to investigate whether adult education (AE) can be used as a tool in facilitating transitions to/in the labor market, using the cross-sectional Adult Education Survey of Turkey (2012). AE is defined as the nonformal education for individuals aged older than 25 years. The outcome of AE is measured by changing jobs for employed and finding a job for the unemployed. Concentrating on employed people, we analyze both the determinants and the outcome of participation in AE for the purpose of changing jobs; and second, concentrating on unemployed people, we analyze both the determinants and the outcome of participation in AE for the purpose of getting employed. We find that once young males who are already working participate in AE for changing work, independent of their education or how AE is financed, they can be successful in doing so. The results of the paper suggest that AE programs offered by the government can serve as a tool in increasing income of the less educated and the unemployed by facilitating their transition to the labor market.

    Protective Effect of Aerobic Exercise on the Nasal Mucosa of Rats Against the Histopathologic Changes in Cigarette Smoke Exposure
    (Sage Publications inc, 2020) Akkoca, Ozlem; Unlu, Ceren Ersoz; Tatar, Ilkan; Sargon, Mustafa Fevzi; Zeybek, Dilara; Oguztuzun, Serpil
    Introduction: Smoking is a public health problem that has been proven to have adverse effects on human health. Aerobic exercise has positive effects on the human body, especially on the respiratory system. Objective: The aim of this experimental animal model study was to determine whether regular aerobic exercise has a protective effect against the harmful effects of cigarette smoke on the nasal mucosa of rats. Methods: A total of 24 male Wistar albino rats were randomly separated into 3 groups of 8: group 1 (cigarette smoking), group 2 (cigarette smoking and exercise), and group 3 (control group). At the end of the experiment period, histopathological (light and electron microscopy) and immunohistochemical (GSTA 1, CYP1A1, and CYP2E1) evaluations were made of the nasal mucosa of the animals. Results: Goblet cell loss and basal membrane thickening were significantly lower in group 2 and group 3 compared to group 1. In the electron microscope evaluation, the inflammatory expressions of the goblet cells were observed in a very small area in group 2. In group 1, these were distributed over large areas between the mucosal cells. There was seen to be significant swelling of the mitochondria in group 1 compared to the other groups. No statistically significant difference was determined between the groups with respect to GSTA1, CYP2E1, and CYP1A1 scores (P> .05). Conclusion: The results of this study showed that regular aerobic exercise has a protective effect against the harmful effects of smoking on the nasal mucosa of rats.

    The Effect of Training, Used-Hand, and Experience on Endoscopic Surgery Skills in an Educational Computer-Based Simulation Environment (ece) for Endoneurosurgery Training
    (Sage Publications inc, 2019) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Isikay, Ilkay; Hanalioglu, Sahin; Suslu, Ahmet E.; Yucel, Taskin; Berker, Mustafa
    Today, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.

    A Retrospective Study of Tracheostomy Care and Decannulation of the Patients in a Palliative Care Center
    (Sage Publications inc, 2024) Zengin, Hilal; Karahan, Zehra Can
    Background: World Health Organization defines palliative care as a multidisciplinary approach to enhancing patients physical, psychological, and emotional well-being. Our study investigated palliative care unit decannulation rates and factors affecting success. Methods: The data of patients hospitalized in the palliative care clinic between 2017 and 2019 were analyzed retrospectively. Demographic data, diagnoses, comorbidities, nutritional status, Norton and Braden Scale scores, day of hospitalization, and discharge direction of the patients were recorded. All patients were evaluated and treated by a multidisciplinary team. Results: One hundred two tracheostomy patients were monitored. Patients in the palliative care clinic had an average stay of 22.19 +/- 13.67 days (median: 21, min: 4, max: 66). Forty-one patients were decannulated. Statistically significant age difference was observed between decannulated and non-cannulated groups, with the decannulated group having a significantly lower mean age (52.10 +/- 20.54, median: 53) compared to the non-decannulated group (61.48 +/- 18.07) (z = -2.516, P = .012). The mean Braden scale score of the decannulated group (14.29 +/- 2.50) was significantly higher than that of the non-decannulated group (12.20 +/- 2.82) (z = 3.823, P < .001), and the mean Norton scale score of the decannulated group (11.34 +/- 2.50) was significantly higher than that of the non-decannulated group (9.46 +/- 2.46) (z = 3.472, P = .001). Conclusion: Patients with tracheostomy can be easily followed and decannulated in palliative care clinics. It is important that a multidisciplinary team is involved in palliative care units. Age, immobility, Norton and Braden scales, and level of consciousness are factors affecting the success of decannulation.

    Flexural Strength Design Criteria for Concrete Beams Reinforced With High-Strength Steel Strands
    (Sage Publications inc, 2012) Baran, Eray; Arsava, Tugba
    This paper summarizes the result of a study investigating the flexural behavior of concrete beams reinforced with high-strength prestressing strands. Thirteen concrete beams reinforced with either conventional reinforcing bars or high-strength strands were fabricated and load tested in the experimental part of the study. No distinct difference was detected between the experimentally obtained cracking patterns of the two groups of beams. For the same reinforcement amount, beams reinforced with high-strength strands exhibited slightly smaller service stiffness than those reinforced with conventional reinforcing bars. A comparison of the measured and numerically predicted response of beam specimens indicated that the cracking load, peak load, and the deformation capacity of concrete beams can be accurately determined by a sectional analysis procedure for both types of reinforcement. The level of ductility present in concrete beams reinforced with high-strength strands is evaluated using the parameter called "displacement deformability ratio." Using the numerically determined maximum reinforcement limits for concrete beams reinforced with high-strength strands, an expression was proposed to be used at the design stage.

    Classification of Intermediate and Novice Surgeons' Skill Assessment Through Performance Metrics
    (Sage Publications inc, 2019) Topalli, Damla; Cagiltay, Nergiz Ercil
    Background. Endoscopic surgeries have become an alternative for open procedures whenever possible. For such types of operations, surgeons are required to gain several skills, whose development needs hands-on practice. Accordingly, gaining these skills today is a challenge for surgical education programs. Despite the development of several technology-enhanced training environments, there are still problems to better integrate these technologies into educational programs. For an appropriate integration, it is critical to assess the skill levels and adapt the training content according to the trainees' requirements. In the literature, there exist several methods for assessing these skill levels. However, there are still problems in practice for objective and repetitive assessment. Methods. The present study aims to estimate the skill levels of participants in surgical training programs in an objective manner by collecting experimental data from residents in an endoscopic surgical simulation environment and gathering performance metrics. Results. It is shown that, by comparing the results of a number of classification algorithms for the best accuracy estimation and feature set, the "novice" and "intermediate" skill levels can be estimated with an accuracy of 86%. Conclusions. The outcomes help surgical educators and instructional system designers to better assess the skill levels of the trainees and guide them accordingly. In addition, objective assessments as highlighted in this study can be beneficial when designing technology-enhanced adaptive learning environments.
