Neutrophil/lymphocyte ratio and Red blood cell distribution width are independent risk factors for 30-day mortality in Gastrointestinal system bleeding patients

Background. In this study, we aimed to examine demographic and endoscopic features of patients with GI bleeding to determine the factors affecting 30-day mortality. Method. Patient’s demographic features, laboratory outcomes, comorbidities, drug use, endoscopy outcomes, Glasgow-Blatchford scores, and mortality status were examined. The factors affecting 30-day mortality were investigated. Results. The mean age of the patients was 58.2±17.4 years, and 72.1% were male patients. 30-day mortality rate was found to be 14.4%. The mean age of patients who died was high (p0.05). Urea, neutrophils, red blood cell distribution width / platelet ratio, neutrophil / lymphocyte ratio and RDW levels were high, and hemoglobin level was significantly low in patients with a mortal progression (p0.05). Glasgow-Blatchford score was significantly higher in patients who died (p<0.05). Conclusion. Many factors affect 30-day mortality in GI bleeding. It should be remembered that follow-up of patients with an advanced age who have comorbidity and impaired hemodynamics should be kept for long, and that these patients are at a high risk for mortality. According to our results, NLR and RDW are independent factors that determine the 30-day mortality in upper GI bleeding

Effect of Ferula elaeochytris root extract on smooth muscle contraction of vas deferens gland in rat

Purpose: To evaluate the effect of Ferula elaeochytris (FE) at the prostatic and epididymal ends of rat vas deferens. Methods: The effects of cumulative concentrations of FE (10 μL; 31.25 mg/μL and 20 μL; 62.5 mg/μL) were investigated on prostatic and epididymal ends of rat vas deferens in the presence of prazosin (0.3 μM), suramin (100 μM), atropine (10 nM) and nitric oxide synthase inhibitor (L-NOARG; 100 μM). The muscle contractions were induced by electrical field stimulation (EFS; 4 Hz, 50 V, 0.15 ms). Calcium (3 and 6 mM) was added into the bath medium while electrical field stimulation (EFS) was in progress. Results: Ferula elaeochytris significantly inhibited the muscle contractions induced by electrical field stimulation (EFS) in a concentration-dependent manner. In the presence of prazosin or suramin, the contractile responses to EFS were significantly inhibited by FE at the prostatic and epididymal ends of vas deferens (p &lt; 0.05). However, this inhibition was not affected by atropine and L- NOARG, suggesting that there is no direct interaction of FE with cholinergic and nitrergic responses. However, in the presence of prazosin or suramin, Ca2+ addition to the organ bath significantly reversed the inhibitory effect of FE at the prostatic and epididymal ends of vas deferens (p &lt; 0.05). Conclusion: These results show an inhibitory effect for the extract of FE on neurogenic contractile activity of prostatic and epididymal ends of vas deferens. This effect of FE may be associated with Ca2+ channels. Keywords: Contractile activity; Electrical Field Stimulation (EFS); Ferula elaeochytris; Rat; Vas deferen

A retrospective observational study comparing hair apposition technique, suturing and stapling for scalp lacerations

AIM: Scalp lacerations are commonly encountered in patients presenting to emergency department with trauma. Lacerations are repaired with suturing, stapling, adhesive tapes, and tissue adhesives. In this study, we aimed to compare the effectiveness of suturing, stapling, and hair apposition techniques used in repair of scalp lacerations in patients who presented to emergency department with scalp laceration. MATERIALS AND METHOD: After obtaining approval of local ethics committee, we examined the effects of the three technique used to repair scalp lacerations on wound healing, complication rate, and patient satisfaction by recording data. Categorical variables were expressed as n and %. X(2) test was used for statistical analysis. A p value less than 0.05 was accepted statistically significant. RESULTS: Our study included a total of 134 patients of whom were treated 37 (27.6%) with hair apposition technique 49, 48 (35.8%) with suturing, and (36.6%) with stapling. There was a significant difference between the scalp repair technique and 7th and 15th day patient satisfaction rates in favor of the hair apposition technique (p < 0.05). There was a significant difference between the scalp repair technique and cosmetic problems after 15 days (p < 0.05). Cosmetic problems 15 days after the procedure were significantly lower in the hair apposition technique. CONCLUSION: In patients presenting to emergency departments with linear scalp laceration suturing, stapling, and hair apposition techniques can be safely applied. However, hair apposition technique has the advantages of being more satisfying, and having lower cosmetic problem and complication rates compared with other techniques

Nutritional risk in hospitalized patients: impact of nutritional status on serum prealbumin

OBJECTIVE: Poor recognition and monitoring of nutritional status is the most important cause of malnutrition in hospitalized patients. The aim of this study was to assess the nutritional status of a group of patients and compare the results with their serum prealbumin levels. METHODS: Ninety-seven patients admitted consecutively to the hospital were enrolled in the study. The risk of malnutrition was assessed according to anthropometric data and the Subjective Global Assessment and Nutrition Risk Screening 2002 tools. The nutritional statuses of the patients were compared with their age, gender, body mass index, medical history, weight loss and routine biochemical analyses, including prealbumin and length of hospital stay. RESULTS: According to the Nutrition Risk Screening 2002, 57% of the patients were malnourished or at risk of malnutrition, correlating well with the Subjective Global Assessment (pOBJETIVO: Falha no reconhecimento e acompanhamento do estado nutricional é a razão mais importante da desnutrição em pacientes hospitalizados. Este estudo objetivou avaliar o estado nutricional dos pacientes e comparar os resultados com os níveis séricos de pré-albumina. MÉTODOS: Foram incluídos 97 pacientes no estudo, internados consecutivamente. O risco de desnutrição foi avaliado de acordo com dados antropométricos e com a Avaliação Subjetiva Global e Triagem de Risco Nutricional 2002. Os estados nutricionais dos pacientes foram comparados com suas idades, sexo, índice de massa corporal, histórico médico, perda de peso e análises bioquímicas, incluindo pré-albumina e tempo de permanência hospitalar. RESULTADOS: De acordo com o Triagem de Risco Nutricional 2002, 57% dos pacientes estavam desnutridos ou em risco de desnutrição, apresentando boa correlação com o Avaliação Subjetiva Global (p<0,001, r=0,700). A análise multivariada mostrou correlações positivas entre desnutrição e idade, perda de peso, malignidade e proteína reativa-C (p=0,046, p=0,001, p=0,04 e p=0,002). Um escore ³3 no Triagem de Risco Nutricional 2002 foi associado à internação prolongada (p<0,001). Houve correlação entre pré-albumina sérica e o estado nutricional, independente do número de doenças crônicas e biomarcadores de inflamação (p=0,01). A sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e valor diagnóstico da pré-albumina na avaliação do risco de desnutrição foram de 94%, 32%, 0,67, 0,78 e 69, respectivamente. Após sete dias de suporte nutricional, o risco de desnutrição caiu em 12% (p<0,001) e os níveis séricos de pré-albumina aumentaram em 20% (p=0,003). CONCLUSÃO: Ao invés de refletir o estado nutricional global do paciente, níveis séricos baixos de séricos de pré-albumina podem ser vistos como um sinal de maior risco de desnutrição, exigindo uma avaliação nutricional mais extensa. A análise sérica de pré-albumina pode ser usada para o monitoramento de pacientes recebendo suporte nutricional

FROM THE EDITOR

Hello, Thanks for joining us again in this November 2014 issue (V/2) of Journal of Social Studies Education Research (JSSER). Our journal has completed its 5 years with this current issue. As the family of Association of Social Studies Educators (ASSE), we are extremely delighted and proud to see the blossoms that we first watered in 2009. JSSER has turned to a qualified electronic journal that has been acknowledged and indexed by various indexes in recent years. One of those indexes has been recognized by Turkish Higher Education Council as a database that includes periodicals regarded as publishing quality academic papers that fulfills the requirements for applying associate professorship. Since its foundation, ASSE, the publisher of the JSSER has been playing the role of an instrument to manifest and improve the “New Social Studies Movement” which emerged through the end of 1990s. The mission of JSSER in this context is to meet the requirement for academic periodical, publishing studies on social studies education. Being published as an electronic journal, JSSER gives us an opportunity to take advantages of the so called Information Age. As a matter of fact, today’s electronic journals have a potential to reach more readers than most of the best-selling published periodicals of late 20th Century. Nevertheless, the same technologies present some risks that we cannot keep under control. The problems that the have been experiencing in the preparation processes of the last two issues are in this kind. In this issue, we have also experienced some communication problems as result of the moving of JSSER’s technical substructure to the Turkish Journal Park. As a result, only three papers, whose peer-reviewing processes had completed could be published in this current issue: Rishabh Kumar Mishra “Social Constructivism and Teaching of Social Science”, Hatice Türe and Arife Figen Ersoy “Sosyal Bilgiler Öğretmenlerinin Hoşgörü Algısı” (Social Studies Teachers’ Perceptions of Tolerance) and Feryal Çubukçu “Values Education Through Literary Texts”. These valuable papers have potential to contribute the literature on social studies education. One of the main aims of ASSE was to establish a regular scientific event through which social studies educators from Turkey and abroad get together to share their academic works and ideas. In conjunction with the Faculty of Education of Bolu Abant Izzet Baysal University we are organizing the Fourth International Symposium on Social Studies Education (ISSE) in April 2015. The main theme of ISSE the 4th is “Peace Education”. The preference of this theme emphasizes on our hopes and determination for our envision for peace in the late Ottoman geography, in which guns have still been on fire and people have still been shedding tears. And this could be regarded as something similar to the action of Mustafa Kemal Pasha who thought of about the reconstruction of the country after the war and assembled an “Educational Congress” in Ankara to discuss educational issues, during the most difficult days of the War of Independence in 1921. Adopting this approach, we have been considering putting effort to institutionalize the values of democracy, human rights, justice, freedom of thought and freedom of conscience. As a final remark, I would like to thank everyone who contributed to the production of this issue and special thanks to Assoc. Prof. Dr. Erkan Dinç who acted as issue editor. Best regards and hope to meet you in ISSE the 4th

From the Editor

We, JSSER/SBEAD family, are thrilled to meet with you once again with this latestissue of JSSER. Every issue released boosts our confidence that our future-targets are even closer to reach; our hopes climb higher that in the years to come we shall eventually be able to build a world where peace, freedom and welfare are the only ruling power.While I am writing these lines, there is a civil war breaking out in our close neighbor Syria. Hundreds of thousands of Syrians are facing death every second. They are losing their beloved ones. They are forced to flee their homeland in mass numbers and stuck in refugee camps in southeastern cities of Turkey and Jordan desperately waiting for the days that peace shall prevail in their homeland again. An infinite number of children are dead out of hunger in so many different countries. And yet we should not fall into the dark wells of despair, though we should be fully aware of these brutal facts. That is because next to all these negations there are also so many joyful things taking place in this ever-dwarfing world. For instance, advancement in information and communication technologies made people global citizens. The children of today’s world, the generation next, are not only aware of the fact that children dying of thirst in the 21stcentury Africa but they feel responsible to help them in any way they can. Turkish children, for example, donated their pocket monies and initiated charity events to raise funds for the children in need in African. Indeed, Turkish children have acted as mediators in opening hundreds of wells for the recent years in Kenya, just one example, to meet hundreds of people in need ofdrinking water. Besides, children of modern ages shall no longer take that is taught to them by their future-builders as the only fact because their critical thinking skills and means to use a variety of information sources have escalated so much. The nextgeneration shall manage to build a world better than today if only we as educators and scientists strive harder to train them for this journey

Numerical and experimental investigation of quench process

Numerical and experimental studies have been carried out to investigate the evolution of residual stresses in quenched components induced by temperature gradient and phase transformations. In the numerical analysis, a finite element model is implemented for predicting the temperature field, phase changes with their associated internal stresses in axisymmetrical steel components. The model is verified by several comparisons with other known numerical results. Case studies are performed to investigate the effects of the quench bath temperature and the specimen geometry. Specimen geometry has been analyzed by introducing a hole in a cylinder and varying hole diameter and its eccentricity. Experiments include microstructural examination and X-ray diffraction measurements of surface residual stresses
