Predictive power of different obesity measures for the presence of diastolic dysfunction

Objective: Body mass index (BMI) and waist circumference (WC) as measures of obesity have some limitations. The aim of this study was to evaluate whether one measure could predict the presence of diastolic dysfunction (DD) more accurately than the other measures. Methods: A total of 91 obese patients without any other risk factors for DD were prospectively enrolled. Echocardiographic examination was performed. DD was defined and categorized according to recent guidelines. The study participants were divided into 2 groups according to the presence of DD. Weight, height, and WC were measured; BMI and waist-to-hip ratio (WHR) were calculated; and a body shape index (ABSI) was calculated as WC/(BMI2/3height1/2). The associations between ABSI, BMI, WHR, and WC and the presence of DD were examined using logistic regression analyses. Analysis of covariance was used to examine the differences. Results: WC and BMI were significantly greater in subjects with DD (p=0.049 and 0.051, respectively). A greater BMI, WC, and WHR increased the risk of the presence of DD (BMI-DD: odds ratio [OR]=1.096, p=0.024; WC-DD: OR=1.059, p=0.007; WHR-DD: OR=2.363, p=0.007). After adjustment for age and sex, only BMI continued to be significantly associated with DD (p=0.031). ABSI was not associated with DD. Conclusion: After adjustment for age and sex, BMI was the only predictor of DD in obesity. Despite its limitations, BMI may still be a potentially more accurate measure of DD compared with other obesity measures. © 2018 Turkish Society of Cardiology

Effect’s of Danazol use on the viability of dorsal rat flap

Repaire of large skin defects is one of the most challenging problem on reconstructive surgery. As known that, the most suitable functional and aesthetic way for flaps are preferrable for aesthetic and functional results. But flaps which used for large skin defects lenght are limited. When the flap’s height lenghtens, flap surviving decreases. In this situation, necrosis and tissue lost is encorded. To prevent this problems, symphatolytic agents and anticoagulans which increases blood flow and changes reolytic property of blood are used. Moreover, cell membrane stabilization is attempted to be maintained.Danazol is antiinflammatory agent in the treatment of endometriosis and it has weak gonadotropic activity. In this study twenty female, adult Sprague-Dawley rat were included. Danazol can decrease random pattern skin flap necrosis due to the fact that danazol has anticoagulant and anti-inflammation property. Danazol may used for increasing survival of flap by decresing development of necrosis on distal part of random pattern skin flap. In this article, we mentioned antiinflammatory mechanism of danazol and influence viability of flap

The Relationship Between Aggressive Behavior and Empathic Tendency Levels of Health Workers

Günümüzde bireylerin eğitim seviyelerinin yükselmesi ile birlikte artan kaliteli sağlık hizmetleri talebi, sağlık sektörünü daha fazla rekabete itmektedir. Sağlık sorunlarının neticesinde, içerisinde bulundukları durumu kabullenmeye başlayan hasta ve yakınlarının endişe ve kaygıları yerini öfkeye bırakabilmektedir. Sağlık çalışanlarının bu öfkeyi ele alma biçimi verilen hizmetin kalitesini belirlemektedir. Çalışanların empatik eğilim ve saldırganlık düzeyi bu noktada önem kazanmaktadır. Hasta ve yakınlarının öfkelerine karşı saldırgan davranış sergilemeden empatik iletişime geçebilmek, düşük saldırganlık düzeyi ve yüksek empatik eğilim gerektirmektedir. Saldırgan davranış düzeyi yüksek, empatik eğilim düzeyi düşük sağlık çalışanlarının, öfkeli olmayan hasta ve yakınlarını da öfkelendirme, sağlıkta şiddet olaylarına sebep olma ve verilen hizmetten duyulan memnuniyeti azaltma olasılığı da yüksektir. Araştırma sağlık çalışanlarının empatik eğilim ve saldırganlık düzeyini belirlemek ve birbirleriyle olan ilişkilerini saptamak amacıyla gerçekleştirilmiştir. Araştırmanın örneklemini Konya Numune Hastanesi, Sağlık Bilimleri Üniversitesi Konya Eğitim ve Araştırma Hastanesi ile Beyhekim Devlet Hastanesinde çalışan 428 sağlık çalışanı oluşturmaktadır. Verilerin toplanmasında araştırmacı tarafından hazırlanan kişisel bilgi formu, Dökmen tarafından geliştirilen Empatik Eğilim Ölçeği ve Buss ve Perry tarafından geliştirilen saldırganlık ölçeği kullanılmıştır. Analizlerde sonuçlar 95'lik güven aralığında, 0,05 anlamlılık düzeyinde değerlendirilmiştir. Bu çalışmada Empatik Eğilim Ölçeğinin Cronbach's Alpha katsayısı 0,84, Saldırganlık Ölçeğinin Cronbach's Alpha katsayısı 0,92 bulunmuştur. Saldırganlık Ölçeği alt boyutlarının Cronbach's Alpha katsayısı ise fiziksel saldırganlık 0,84, sözel saldırganlık 0,62, düşmanlık 0,77 ve öfke 0,79 olarak bulunmuştur. Araştırma bulgularına göre sağlık çalışanlarının empatik eğilim toplam puan ortalaması 66,71, saldırganlık ortalama madde puanı 2,69 olarak tespit edilmiştir. Empatik eğilimin cinsiyet, yaş, öğrenim düzeyi ile saldırganlık düzeyinin cinsiyet, medeni durum, görev yılı ile ilişkili olduğu saptanmıştır. Empatik eğilim ile saldırganlık düzeyi arasında negatif yönlü anlamlı ilişki tespit edilmiştir. Bu sonuca göre sağlık çalışanlarının empatik eğilim düzeyleri arttıkça saldırganlık düzeyleri azalmaktadır.Today, as level of education of individuals increases, demand for higher quality health services pushes the health sector to compete more. As a result of health problems, anxiety and worries of patients and their relatives who are beginning to accept their situation, might be replaced by anger. Health personnel’s way of dealing with this anger determines the quality of service provided. Empathic tendency and aggression levels of the personnel gain importance at this point. Empathic communication without aggressive behavior against anger of patient and his/her relatives requires low level of aggression and high empathic tendency. Health workers with high levels of aggressive behavior and low empathic tendencies, are likely to provoke patients and their relatives who are not angry, cause violence in health and reduce satisfaction with the service provided.Research was conducted to determine levels of empathic tendency and aggressiveness of healthcare personnel and their relations with each other. Research's sample group contains 428 healthcare workers working in Konya Numune Hospital, Health Sciences University Konya Education and Research Hospital and Beyhekim State Hospital. While collecting data, personal information form prepared by researcher, Empathic Tendency Scale developed by Dökmen and aggression scale developed by Buss and Perry were used.In the analyzes, results were evaluated at 95 confidence interval, 0,05 significance level. In this study, Cronbach Alpha coefficient of Empathic Tendency Scale was found as 0,84 and Cronbach's Alpha coefficient of the Aggression Scale was found as 0,92. Cronbach's Alpha coefficient of Aggression Scalesub-dimensions was 0,84 for physical aggression, 0,62 for verbal aggression, 0,77 for hostility and 0,79 for anger.According to research findings, total point average of empathic tendency of health personnel was determined as 66,71 and total point average of aggression was determined as 2,69. It was determined that empathic tendency was related to gender, age, education level and aggression level was related to gender, marital status, duty year. Negative significant relation between empathic tendency and level of aggression was determined. According to this result, as levels of empathic tendency of health personnel increase, aggression levels decrease

The Role of Surface Modification Methods for Sustainable Textiles

Sustainability aims to provide a livable future for the next generations. Studies on reducing high chemical, energy, and water consumption make significant contributions to sustainability in many sectors. The textile sector consists of many processes such as fiber production, yarn and fabric production, dyeing, and finishing processes. Each of these processes consumes a significant amount of water and energy. Cotton fiber production consumes approximately 1559 kg of fresh water per kg, and polyester fiber production consumes approximately 108 kWh of electricity per kg. Clean water consumption can be up to 200 L/kg in subsequent processes such as bleaching, dyeing, printing, and finishing. Surface modification techniques in textile production can play a role in sustainability, especially in areas such as reduction, reuse, and recycling. In this chapter, we aim to investigate the effects of surface modification techniques on reducing chemical, energy, and water consumption in textile production, improving textile performance properties, and altering the service life of textiles

Determination of digital technologies preferences of educational researchers

Purpose – This study aims to investigate the preferences of 96 educational researchers on the use of digital technologies in scientific research. Design/methodology/approach – The study was designed as a quantitative-dominant sequential explanatory mixed-method research. Findings – Despite the spreading use of advanced technologies of big data and data mining, the most preferred digital technologies were found to be data analysis programs, databases and questionnaires. The primary reasons of using digital technology in scientific research were to collect data easily and quickly, to reduce research costs and to reach a higher number of participants. Originality/value – The use of digital technologies in scientific research is considered a revolutionary action, which creates innovative opportunities. Through digitalized life, probably for the first time in history, the educational researchers have analytical information, which we can benefit from more than the individual's own statements in research involving human factor. However, there are a few studies that investigated the preferences of educational researchers who use digital technologies in their scientific research

COMPARISON OF CHANGES IN THE ANKLE AFTER UNICONDYLAR KNEE ARTHROPLASTY AND HIGH TIBIAL OSTEOTOMY

Objectives: We aimed to compare the changes in the coronal alignment of the ankle joints and their clinical effects after high tibial osteotomy (HTO) and unicondylar knee arthroplasty (UKA). Methods: 50 HTO and 54 UKA patients who were operated on for medial knee osteoarthritis between 2013 and 2018 were retrospectively evaluated. The hip-knee-ankle angle (HKA), the medial proximal tibial angle (MPTA), the tibial plafond inclination (TPI) and the talar inclination (TI) angles were measured before and after operation. Visual analog scale (VAS), short form 36 (SF-36), and ankle-hindfoot scale (AHS) scores of both groups were evaluated and recorded. Results: Angular changes in the HKA, MPTA, TPI and TI values showed significantly greater values in the HTO group (p<0.001). When asymptomatic and symptomatic cases were compared, it was found that changes in the HKA, TPI and TI values were significantly greater in symptomatic cases in the HTO group (p<0.05). A significant decline was observed in the VAS, SF-36 and AHS scores in the HTO group in the postoperative period (p<0.05). In intergroup evaluations, a significant decline was detected in pain and functional scores of the HTO group when compared to the UKA group (p<0.05). Conclusion: Unicondylar knee arthroplasty can be a good alternative to HTO in selected cases for postoperative ankle complaints.Level of Evidence III; Therapeutic Studies Investigating the Results of Treatment

Investigation of TAp63 gene expression and follicle count using melatonin in cisplatin-induced ovarian toxicity

Background: Premature ovarian failure is among the most important side effects of chemotherapy during reproductive period. Preserving ovarian function is gradually gaining importance during oncologic treatment. The present study aims to investigate the potential of melatonin to protect from cisplatin-induced ovarian toxicity in rats.Methods: Twenty-nine female rats were divided to three groups: Saline control group (group 1), cisplatin group (group 2), and cisplatin and melatonin group (group 3). While the rats in groups 2 and 3 were administered 5 mg/kg single dose of cisplatin via intra-peritoneal (IP) route, the rats in group 3 were started on melatonin (20 mg/kg IP) before cisplatin administration and continued during 3 consecutive days. Ovaries were removed one week after cisplatin administration in all groups. Blood samples were obtained before the rats were decapitated. Histological evaluation, follicle count, and classification were performed. TAp63 mRNA expression was evaluated using mRNA extraction and real-time polymerase chain reaction (PCR) method. Serum estradiol (E2) and anti-Mullerian hormone (AMH) values were measured with enzyme immune-assay technology.Results: While primordial follicles were seen to decrease in group 2 as compared to group 1 (p=0.023), primordial follicle count was observed to be preserved significantly in melatonin group as compared to group 2 (p=0.047). Moreover, cisplatin-induced histo-pathological morphology was preserved in favor of normal histology in melatonin group. A significant difference was not observed between groups with regard to mean serum AMH and E2 values (p=0.102 and p=0.411, respectively). While TAp63 gene expression significantly increased in group 2 as compared to control group (p=0.001), we did not detect a statistically significant difference in cisplatin and melatonin group, although gene expression decreased (p=0.34).Conclusions: We conclude that concurrent administration of melatonin and cisplatin may protect from ovarian damage
