Evaluating the clinical significance of diazepam binding inhibitor in alzheimer's disease: A comparison with inflammatory, oxidative, and neurodegenerative biomarkers

Introduction: Alzheimer's disease (AD) is one of the pathologies that the scientific world is still desperate for. The aim of this study was the investigation of diazepam binding inhibitor (DBI) as a prognostic factor for AD prognosis. Methods: A total of 120 participants were divided into 3 groups. Forty new diagnosed Alzheimer patients (NDG) who have been diagnosed but have not started AD treatment, 40 patients who diagnosed 5 years ago (D5YG), and 40 healthy control groups (CG) were included in the study. Levels of DBI, oxidative stress, inflammatory, and neurodegenerative biomarkers were compared between 3 groups. Results: Plasma levels of DBI, oligomeric Aβ, total tau, glial fibrillary acidic protein, α-synuclein, interleukin (IL) 1β, IL6, tumor necrosis factor α, oxidative stress index, high-sensitive C-reactive protein, and DNA damage were found higher in D5YG and NDG as compared to CG (p < 0.001). On the contrary, plasma levels of total thiol, native thiol, vitamin D and vitamin B12 were lower in D5YG and NDG as compared to CG (p < 0.001). Discussion: DBI may be a potential plasma biomarker and promising drug target for AD. It could help physicians make a comprehensive evaluation with cognitive and neurodegenerative tests

The relationship between insulin resistance, metabolic syndrome and nonalcoholic fatty liver disease in non-obese non-diabetic Turkish individuals: a pilot study

Background/Aims: Nonalcoholic fatty liver disease is related to obesity, metabolic syndrome, and insulin resistance. Nonalcoholic fatty liver disease and metabolic syndrome may also be encountered in non-obese, non-diabetic individuals, and there are no published data about the prevalence of these conditions in non-obese, non-diabetic Turkish subjects. We aimed to determine the difference between non-obese, non-diabetic nonalcoholic fatty liver disease patients and healthy controls in terms of insulin resistance and metabolic syndrome in Turkish subjects. Materials and Methods: Non-obese, non-diabetic individuals (n=219) were enrolled. The cohort was divided into two groups according to presence of steatosis in ultrasonography: nonalcoholic fatty liver disease group (n=143) and healthy control group (n=76). Insulin resistance and metabolic syndrome were analyzed and compared between the two groups. Results: The prevalences of metabolic syndrome (32.2% vs. 5.3%, respectively; p<0.001) and insulin resistance (46.2% vs. 9.2%, respectively; p<0.001) were significantly higher in the nonalcoholic fatty liver disease group. According to multiple logistic regression analysis, age (odds ratio 1.534; p=0.0032), insulin resistance (odds ratio 1.074; p<0.001), and serum ALT levels (odds ratio 1.102; p<0.001) were independently associated with nonalcoholic fatty liver disease. Conclusion: Insulin resistance and metabolic syndrome are not rare in non-obese, non-diabetic Turkish subjects with nonalcoholic fatty liver disease. Ultrasonographically detected fatty liver was independently associated with insulin resistance, irrespective of the presence of metabolic syndrome

The importance of costoclavicular space on possible compression of the subclavian artery in the thoracic outlet region: a radio-anatomical study

OBJECTIVES: The purposes of this study were to identify possible compression points along the transit route of the subclavian artery and to provide a detailed anatomical analysis of areas that are involved in the surgical management of the thoracic outlet syndrome (TOS). The results of the current study are based on measurements from cadavers, computed tomography (CT) scans and dry adult first ribs. METHODS: The width and length of the interscalene space and the width of the costoclavicular passage were measured on 18 cervical dissections in 9 cadavers, on 50 dry first ribs and on CT angiography sections from 15 patients whose conditions were not related to TOS. RESULTS: The average width and length of the interscalene space in cadavers were 15.28 ± 1.94mm and 15.98 ± 2.13 mm, respectively. The widths of the costoclavicular passage (12.42 ± 1.43mm) were significantly narrower than the widths and lengths of the interscalene space in cadavers (P < 0.05). The average width and length of the interscalene space (groove for the subclavian artery) in 50 dry ribs were 15.53 ± 2.12mm and 16.12 ± 1.95mm, respectively. In CT images, the widths of the costoclavicular passage were also significantly narrower than those of the interscalene space (P 0.05). CONCLUSIONS: Our results showed that the costoclavicular width was the narrowest space along the passage route of the subclavian artery. When considering the surgical decompression of the subclavian artery for TOS, this narrowest area should always be kept in mind. Since measurements from CT images and cadavers were significantly similar, CT measurements may be used to evaluate the thoracic outlet region in patients with TOS

Clinical Features and Surgical Results in Harada-Ito Surgery Patients

Symptomatic excyclotorsion is an important clinical problem, especially in acquired superior oblique muscle palsy. Excyclotorsion can disrupt the fusion and cause torsional diplopia. Harada-Ito surgery (HI) is a widely used method for treating excyclotorsions. This method relieves the torsional diplopia by increasing the effect of the incyclotorsion. In this study, we aimed to report the clinical features of patients with torsional diplopia due to acquired trochlear nerve palsy and the results of HI surgery in these patients
