Assessment of obesity frequency and related factors on ındividuals attending to the department of nutrition and dietetics

Amaç: Bu çalışma, Ankara Üniversitesi Tıp Fakültesi İbn-i Sina Eğitim ve Araştırma Hastanesi, Beslenme ve Diyet Bölümü’ne başvuranlarda obezite durumu ve etkili faktörlerin belirlenmesi amacıyla yapılmış bir araştırmadır. Çalışma Planı: Araştırma tanımlayıcı bir araştırma olup, ilgili bölüme başvuran ve araştırmaya katılmayı kabul eden 450 kişi üzerinde yürütülmüştür. Veri toplama aracı olarak 5 bölüm ve 59 so- rudan oluşan anket formu kullanılmıştır. İstatistiksel analizlerde ki-kare testi uygulanmış, yanılma olasılığı 0.05 olarak alınmıştır. Bulgular: Araştırma grubunda obezite oranı %28.0 olarak bulunmuştur. Obezite durumu cinsiyet, yaş, medeni durum, öğrenim düzeyi, meslek, aylık gelir gibi sosyodemografik özelliklerle ilişkili bulunmuştur. Evlilik süresi, çocuk sayısı, çocukluk çağında şişman olma durumu, daha önce obezite tedavisi görme ve daha önce zayıflamak için diyet yapma durumunun ve menopozun obezite durumunu etkilediği belirlenmiştir. Ailesinde obez bir kişi bulunanların, ana ve ara öğünleri atlayanların daha yüksek oranda obez olduğunun belirlenmesi, obezitenin beslenme biçimi ile ilişkili olduğunu düşündürmektedir. Sonuç: Obezitenin ortaya çıkmasında beslenme alışkanlıklarının yanı sıra, yaşam biçimi, yaş, cin- siyet ve sosyoekonomik özellikler gibi birden çok faktörün etkili olduğu düşünülmektedir. Bu nedenle yüksek risk taşıyan bireylere öncelik verilerek değiştirilebilir faktörlere yönelik korunma ve müdahale çalışmalarının düzenlenmesinin, obezitenin önlenmesi ve kontrolünde etkili olacağı düşünülmektedirObjectives: This research was planned to assess the obesity and related factors on individuals ap- plying to the department of Nutrition and Dietetics, İbn-i Sina Training and Research Hospital, Medi- cal School, Ankara University. Study Design: This descriptive study was conducted on 450 people accepted to participated in the study. The data were collected by a questionnaire including 5 sections and 59 questions. In statisti- cal analyses, test of chi-square was used and p value below 0.05 was accepted to be statistically significant. Results: The obesity ratio was 28.0% and obesity was associated with some sociodemographic characteristics such as gender, age, marital status, educational level, and monthly income. Duration of marriage, number of children, obesity in childhood, having obesity treatment before, dieting for loosing weight and menoupose were indicated to influence the obesity. High obesity ratios in participants having family history of obesity, neglecting main and in-between meals were contributed that obesity was related to nutritional habits. Conclusion: In the development of obesity it is thought that multiple factors such as nutritional habits, life-style, age, gender, and sociodemographic characteristics are effective. Therefore, for the prevention and control the obesity, it is suggested to develop modifiable risk factor centered pre- ventive and interventional studies prioritizing individulas under high risks will be convenient

Evaluation of articular eminence pneumatization using cone beam computed tomography

Aim. Knowledge about the anatomy of the temporomandibular joint (TMJ) and its surrounding structures is mandatory for success in surgical interventions and for understanding the pathway of spread of infections in this region. This study aims to investigate the anatomy and morphology of pneumatized articular eminence (PAT) using cone beam computed tomography (CBCT) imaging in a group of patients. Methods. A retrospective study on 825 patients (377 males, 448 females) aged between 18 and 91 years was performed using sagittal and coronal CBCT images. PAT was defined as non-expansile, nondestructive cyst-like radiolucency in the zygomatic process of the temporal bone, which appears similar to the mastoid air cells. It was classified in two groups as unilocular and multilocular. Statistical comparison of gender, age and localization was performed using chi-square test and correspondence analysis. P0.05). Conclusion. Pneumatization of the articular eminence is a challenging entity for TMJ surgery and spread of infections in this region. Practitioners who are dealing with TMJ surgery and pathology should have detailed information about this anatomical variation since it may cause serious complications

Influence of Blood Collection Systems on Coagulation Tests

OBJECTIVE: Coagulation tests are influenced by pre-analytic conditions such as blood collection systems. Change of glass collection tubes with plastic ones will cause alteration of the test results. The aim of this study was to compare three plastic blood collection tubes with a standard glass blood collection tube and each plastic collection tube with the other two for possible additional tube-to- tube differences. METHODS: A total of 284 blood samples were obtained from 42 patients receiving warfarin during their routine controls, besides 29 healthy volunteers. Subgroup analyses were done according to health status. RESULTS: Our study demonstrated that different blood collection tubes have a statistically significant influence on coagulation tests. The magnitude of the effect depends on the tube used. However most of the tests performed on samples obtained from any tube correlated significantly with results obtained from other tube samples. CONCLUSION: Although blood collection tubes with different brands or properties will have distinct effects on coagulation tests, the influence of these blood collection tubes may be relatively small to interfere with decision-making on dose prescription, therefore lack clinical importance. Correlations between the results showed that, one of these plastic blood collection tubes tested in our study, can be used interchangably for a wide variety of coagulation assays

Effect of glucosamine chondroitine sulphate on repaired tenotomized ratachilles tendons

Amaç: Bu deneysel hayvan çalışmasında glukozamin kondroitin sülfatın (glcN-CS) sıçan Aşil tendonları üzerindeki etkisi değerlendirildi. Gereç ve yöntemler: Otuz adet 300-350 g ağırlığında Wistar albino türü sıçan rastgele iki gruba ayrıldı. Grup A: Aşil tendonları tenotomize edildi, tamir yapıldı ve glcN-CS ağızdan verildi. Grup B: Aşil tendonları tenotomize edildi ve tamir yapıldı. Bütün sıçanlar pelet yem ile beslendi. Her gruptan beşer sıçan 4, 8. ve 12. haftalarda sakrifiye edildi. Her gruptan üç adet tendon örneğinin gerilme gücü biyomekanik olarak test edildi ve iki örnek de immünohistokimyasal boyama ve hematoksilen ve eozin boyama yapılarak histopatolojik açıdan analiz edildi. Karşı taraf Aşil tendonları da gruplandırıldı ve kontrol olarak analiz edildi (grup C ve D). Bulgular: Histolojik sonuçlarda, grup A’da daha az enflamasyon ve daha düzgün kollajen oluşumu olduğunu görüldü. Biyomekanik testlerde 8. haftada A grubunda istatistiksel olarak anlamlı olmasa da daha yüksek tendon güçleri kayıt edildi (554.84N, p0.078). Glukozamin kondroitin sülfat verilen hayvanlarda tendon gerilim güçleri istatiksel olarak anlamlı bir şekilde yüksek bulundu (50.015.62N, p0.014). Sonuç: Glukozamin kondroitin sülfat sıçanlarda Aşil tendonu iyileşme sonuçlarını geliştirmiştir. Bu sonuç enflamasyonu azaltması ve kollajen sentezini uyarması ile ilişkili olabilir. Her ne kadar glcN-CS sadece osteoartriti bulunan hastalarda semptom ve belirtileri geriletmesi için önerilse de spor yaparken oluşan yumuşak doku yaralanmalarının tedavisi için de tercih edilebilir.Objectives: We evaluated the effects of glucosamine chondroitine sulphate (glcN-CS) on rat Achilles tendons in this experimental animal study. Materials and methods: Thirty Wistar albino type rats weighing 300-350 g were randomly grouped into two. Group A: Achilles tendons were tenotomized, repaired and, glcN-CS given orally. Group B: Achilles tendons were tenotomized and repaired. All the rats were fed with pellet chow. Five rats in each group were sacrificed at 4, 8, and 12 weeks interval. Tensile strength of three tendon specimen from each group were tested biomechanically and two specimen were analysed histopathologically via immunohistochemical staining and hematoxylin and eosin staining. Contralateral side Achilles tendons were also grouped and analyzed as controls (group C and D). Results: Histological results showed well organized collagen formation and less inflammation in group A. Biomechanical testing showed higher tendon strength in group A at eight weeks which is not statisticaly significant (55.3±4.84N, p0.078). Rats which were were given glcN-CS had greater tendon strength which is statisticaly significant (50.01±5.62, p0.014). Conclusion: Glucoseamine chondroitine sulphate improved results of Achilles tendon healing in rats. This result might be due to decreased inflammation and stimulation of collagen synthesis. Although glcN-CS is recommended only in osteoarthritic patients to relieve symptoms and signs it can also be prefered in treatment of soft tissue injuries formed during sports activities
