    Malnutrition in hospital is a significant problem which involves clinical complication risks, lengthened hospital stay and worsening prognosis. In order to overcome this problem, it is important to identify malnutrition in patients. The aim of this study was to retrospectively research the malnutrition risk of patients at time of admission and to create awareness about the importance of malnutrition screening. This research is a cross-sectional descriptive retrospective study which screened inpatients in İstanbul Sultan Abdülhamid Han Education and Research hospital from August 2018 to January 2019. Research data and NRS-2002 scores were retrospectively gathered from patient files. Between the dates of the study, a total of 10,060 patients stayed in the hospital and of these 490 (4.9%) were identified to be malnourished. Of these patients, 0.87% developed malnutrition after admission. The clinic with highest malnutrition was the anesthesia intensive care (25.9%). There was a significant increase identified in NRS-2002 scores with age (p=0.001); as NRS-2002 scores increased the mortality rates were found to significantly increase (p=0.015). The mortality in the patient group with NRS-2002 scores of 7 was 50%. Malnutrition screening will contribute to monitoring malnourished patients from time of admission and reducing mortality rates. According to the results of our study, the malnutrition risk is higher among elderly patients and as NRS-2002 score increases mortality increases. Due to this correlation between inpatient NRS-2002 scores and mortality, it was concluded that rapid screening and close surveillance of nutritional interventions for patients with high scores are important in terms of mortality..

    The effect of tuberositas tibia osteotomy on patellofemoral joint pressure: An experimental animal study

    Aim: To demonstrate the decrease in patellofemoral pressure with an anterior elevation of tuberositas tibia. Therefore, we have performed Maquet’s Technique to evaluate the patella pressure on femoral trochlea by biomechanically in an animal experiment model. Methods: This study includes total of 42 knees of 21 New Zealand rabbits. Animals were divided into two groups. The first group including 21 right knees was designated as the control group. In the second group including 21 left knees, anterior elevation of tuberositas tibia (Maquet’s technique) was performed. Pressure measuring film layer “prescala” (Fujifilm, Japan) was placed on the patellofemoral joint under anesthesia in both groups. Mean values of both average and maximal pressure measurements in two groups were compared. Results: There is a statistically significant difference in between average pressure and maximum pressure in the right and left legs of the rabbits. Average pressure and maximal pressure at rabbit knees performed Maquet’s procedure were significantly lower than knees without Maquet’s procedure. Conclusion: Anterior elevation of tuberositas tibia is successful in reducing patellofemoral joint pressure which can be used in cases with patellofemoral pain syndrome non-responding to conservative treatment

    Assessment of shear bond strength and microleakage of fissure sealant following enamel deproteinization : an in vitro study

    To evaluate the effect of two different deproteinizing agents (5.25% sodium hypochlorite and Papacarie®) prior to acid etching on the shear bond strength and microleakage of a fissure sealant material. A total of 123 extracted noncarious human third molar teeth were randomly divided into three groups for each test: acid etching alone (control) (C), sodium hypochlorite (NaOCl), and Papacarie Duo® (PC). The shear bond strength tests were performed using a universal testing machine, and microleakage was evaluated using a dye penetration method. The mean shear bond strength values obtained in Group C were significantly lower than those of Group NaOCl and Group PC (p=0.0001). There were no significant differences between Group NaOCl and Group PC (p>0.05). No statistically significant difference was observed among the groups in terms of microleakage (p>0.05). Papacarie Duo® and 5.25% sodium hypochlorite treatments before etching increased the shear bond strength of the fissure sealant. However, pre-treatment with these agents did not decrease the microleakage between teeth and sealant

    Overview of Kizildere Geothermal Power Plant in Turkey

    Achieving sustainable development is a target that is now widely seen as important in worldwide public opinion. In this context, the utilization of renewable energy resources such as solar, geothermal and wind energy appears to be one of the most efficient and effective ways of achieving this target. Recently, power generation from geothermal energy has become of big importance in Turkey, which is located on the Mediterranean sector of the Alpine-Himalayan Tectonic Belt and is among the first seven countries in abundance of geothermal resources around the world. The main objective in doing the present study is twofold, namely: (a) to investigate Turkey's geothermal energy potential for power generation and (b) to overview the Denizli-Kizildere geothermal power plant (DKGPP) with an installed capacity of 20.4 MWe, which is at present the only operating geothermal power plant of Turkey. Based on the drilling data, which have been gathered to date, Turkey's geothermal energy potential for power generation is determined to be 764.81 MWe. Electricity generation projections of Turkey are also 500 MWe from Germencik, Kizildere, Tuzla and several of the other fields by the year 2010 and 1000 MWe by 2020. The Denizli-Kizildere geothermal field has an estimated capacity of 200 MWe. The DKGPP was put into operation in 1984 and has been operated since then. It produced an electrical energy of 89,597 MWh in 2001, representing an electric power of 10.6 MWe in the same year. Present applications have shown that in Turkey, geothermal energy is a promising alternative and can make a significant contribution towards reducing the emission of greenhouse gases. As the public recognizes the projects, the progress will continue. (C) 2003 Elsevier Ltd.

    Turkey is located on the Mediterranean sector of Alpine-Himalayan Tectonic Belt with many grabens, acidic volcanism, hydrothermal alteration zones, numerous hot springs and fumaroles. The data gathered since 1962 indicate that Turkey has a high geothermal energy potential. By comparison, it is among the first seven countries in abundance of geothermal resources around the world, while the share of its potential used is only about 2%. This means that considerable studies on geothermal energy could be conducted in order to increase energy supply and to reduce atmospheric pollution in Turkey. The main objective of the present study is threefold, namely: (1) to overview Turkey's geothermal fields suitable for power generation together with their possible utilization opportunities, (2) to present problems encountered and research projects developed in the Denizli-Kizildere geothermal field with an estimated capacity of 200 MWe and (3) to assess the current status of geothermal energy use for electric energy production in Turkey. The Denizli-Kizildere geothermal power plant with an installed capacity of 20.4 MWe, which is, at present, the only operating geothermal power plant of Turkey, was put into operation in 1984, while electricity from geothermal energy has been produced commercially since 1913. This plant produced on average an electrical energy of 84,920 MWh in the period between 1998-2001, representing an average electric power of 10.45 MWe in the same period. Parallel to the development of the geothermal energy utilization in the country, it is projected that, by the years 2010 and 2020, the total geothermal power installed capacity will increase to 500 MWe and 1000 MWe, respectively
