EFFECT OF HEALTH ANXIETY ON GLYCEMIC CONTROL IN PATIENTS WITH TYPE II DIABETES MELLITUS: A SINGLE CENTER, CROSS SECTIONAL STUDY.

Context: Health anxiety was rarely investigated in Type II Diabetes Mellitus (T2DM). Objectives: The present study examines the effect of health anxiety on glycemic control and evaluates factors associated with health anxiety in patients with T2DM according to HbA1c level. Design: Cross-sectional. Subjects and Methods: Socio Demographic Data Form (SDVF), Health Anxiety Inventory-Short Form(SHAI), The Hospital Anxiety and Depression Scale (HADS) were administered to 185 patients with Type II DM . Patients were divided into two groups according to HbA1 c level (HbA1c levels below 7 (Group 1, n=69) and above 7 (Group 2, n=185)). We analyzed prevalence of health anxiety, factors associated with health anxiety between poor and good glycemic control and evaluated of T2DM patients according to health anxiety scale scores. Results: SHAI scale scores were low in 52 (28%), intermediate in 58 (31.2%) and high in 76 (40.8%) of the patients. We found the severity of depressive symptoms was positively correlated with health anxiety in both groups. As a result of this study, there was a relationship between high education and low socioeconomic level, having a job, exercise and anxiety level and low SHAI score in T2DM patients. Depression, stressful life events in the last 6 months were related with high health anxiety. Although the level of health anxiety was not different between groups, low blood sugar levels were related with high health anxiety. Conclusions: This study found that the prevalence of health anxiety in T2DM patients was higher than expected irrespective to poor or good glycemic control, but level of health anxiety in patients with T2DM is not a good predictor for the HbA1c level.

The effect of using personal protective equipment and aerosol box in the emergency department on the intubation times.

Background: Endotracheal intubation is a procedure commonly performed in the emergency department (ED). Endotracheal intubation poses a risk of exposure to infectious aerosol droplets. Aim: The present study aims to test the effect of using an aerosol box (AB) and personal protective equipment (PPE) on the intubation time while performing endotracheal intubation manikin. Subjects and Methods: The study participants (11 emergency specialists, 11 emergency physicians, and 11 general practitioners) performed endotracheal intubation on a training manikin in three different airway simulations. Simulation 1 had neither PPE nor AB, simulation 2 had PPE, and simulation 3 had both PPE and AB. The intubation times, the number of intubation attempts, and the discomfort caused by the AB were recorded. Results: There was no significant difference in the number of intubation attempts between the physicians according to their position and airway simulations (p > 0.05). There was a significant difference at all time points except for the time to endotracheal tube cuff inflation in three different airway simulations using PPE and an AB (p < 0.05). The median intubation times were longer using PPE and an AB. Conclusion: The use of PPE and an AB significantly increases the total intubation time.

Effects chemical disinfectants on surface roughness of conventional impression materials used for dental prosthetic procedures.

Background to Aim: To compare the effects of disinfectants on surface roughness of the conventional impression materials following chemical disinfection procedures. Materials and Methods: Equal numbers (65 for each impression material) of disc-shaped (15 × 3 mm) samples (Total n = 195) were fabricated from polyvinyl siloxane (Zhermack Elite), polyether (3M Impregum Penta Soft), and vinyl siloxane ether (Kettenbach Identium Lightbody) impression materials. Each impression material group was divided into five subgroups including one control group (n = 13). Impression material samples were immersed in CaviCide for 3 min, Zeta 7 solution for 10 min, and 5.25% sodium hypochlorite solution for 3 and 10 min. Surface roughness (Ra) was measured using a profilometer (Mitutoyo-SJ 410, Mitutoyo Corp.). The study data were analyzed statistically. Results: A statistically significant difference was found among impression materials and disinfectants in terms of surface roughness (P < 0.05). Polyvinyl siloxane material showed a lower Ra value compared to Polyether and VSE materials; while polyether material showed a significantly lower Ra value compared to VSE material. Ra values of the control group were significantly lower than the disinfectant group immersed in 5.25% NaOCl solution for 10 min. Conclusion: Among all impression materials, polyvinyl siloxane showed the least surface roughness following disinfection procedures. Impression disinfectants that are specially designed for disinfecting dental impressions resulted in less surface roughness in all impression materials. With this study, it was aimed to obtain a smooth and clear model for the production of correct and compatible prostheses in the laboratory while at the same time purifying the impressions from microorganisms.

Serum levels of gamma-glutamyl transpeptidase in relation to HCC human biology and prognosis.

BACKGROUND AND AIM: Hepatocellular carcinoma (HCC) biomarkers are limited, as even the best studied, alpha-fetoprotein (AFP), is elevated in no more than 50% of HCC patients. The aim was to evaluate several serum liver function tests in relation to survival and tumor characteristics in a large cohort of Turkish HCC patients. METHODS: We retrospectively examined the serum levels of gamma glutamyl transpeptidase (GGT) in relation to patient survival. RESULTS: Kaplan-Meier analysis showed that only GGT and albumin amongst liver function tests, were significantly associated with survival. Survival worsened with increase in GGT levels semi-quantitatively. Increase in GGT levels was also found to significantly correlate with an increase in maximum tumor diameter from 4.5 to 7 cm, a 20-fold increase in serum alpha-fetoprotein level, an increase in tumor multifocality from 20 to 54% of patients, and a doubling in percent of patients with portal vein thrombosis (PVT) from 20 to 40%. Serum GGT levels also showed significant survival differences for patients with low AFP levels. A doublet combination of serum GGT with albumin levels was associated with higher hazard ratios in a Cox regression analysis, as compared with single parameter GGT. The combination parameter pair was also prognostically useful in the low-AFP patient subcohort and was associated with significant differences in patient tumor characteristics. CONCLUSIONS: Serum GGT levels and especially combination serum GGT plus albumin levels, were significantly associated both with HCC patient survival and tumor aggressiveness characteristics, regardless of AFP levels in a large Turkish cohort. This might be especially useful since the majority of HCC patients do not have elevated levels of AFP.

Plasma lipids, tumor parameters and survival in HCC patients with HBV and HCV.

INTRODUCTION AND AIMS: Hepatocellular carcinoma (HCC) is a consequence of chronic liver disease, particularly from hepatitis B or C and increasingly from obesity and metabolic syndrome. Since lipids are an important component of cell membranes and are involved in cell signaling and tumor cell growth, we wished to evaluate the relationship between HCC patient plasma lipids and maximum tumor diameter and other indices of HCC human biology. METHODS: We examined prospectively-collected data from a multi-institutional collaborative Turkish HCC working group, from predominantly HBV-based patients, for plasma lipid profiles, consisting of triglycerides, total cholesterol, LDL-cholesterol (LDL) and HDL-cholesterol (HDL) and compared these with the associated patient maximum tumor diameter (MTD), portal vein thrombosis, alpha-fetoprotein (AFP) and also with patient survival. RESULTS: We found that both low HDL (p=0.0002) and high LDL (p=0.003) levels were significantly associated with increased MTD, as well as in a final multiple linear regression model on MTD. The combination of low HDL combined with high HDL levels were significant in a regression model on MTD, PVT and an HCC Aggressiveness Index (Odds Ratio 12.91 compared to an Odds Ratio of 1 for the reference). Furthermore, in a Cox regression model on death, the HDL plus LDL combination had a significantly higher Hazard Ratio than the reference category. CONCLUSIONS: Low plasma HDL, high plasma LDL and especially the combination, were significantly related to more aggressive HCC phenotype and the combination was significantly related to a higher Hazard Ratio for death.

Effect of EGF on Bax, Bcl-2 and Fas expression in ulcerous disease and N87 cell line.

BACKGROUND: To evaluate the effect of epithelial growth factor (EGF) in primary culture of ulcer patients and N87 cell line on expressions of apoptotic genes. METHODS: Ulcer patients who attended Gastroenterology Clinic of Mersin University Medical Faculty were included in this study. Three different doses of EGF were applied to the primary culture of biopsy samples from ulcer patients and gastric cancer cell-line (ATCC-NCI-N87) . The expression levels of Bax, Bcl-2 and Fas genes were measured with quantitative real-time PCR (qRT-PCR). RESULTS: ΔΔCT analysis with qRT-PCR revealed no significant change in gene expression of Bax, Bcl-2 or Fas within the ulcer, normal tissue and gastric cancer. No significant change was determined between Bax and Bcl-2 gene expression levels and applied EGF doses when groups were compared for each EGF dose. On the other hand, when 50 ng/µl of EGF was administered, Fas mRNA expression level was significantly lower in the gastric cancer cell line compared to patients with ulcer and normal gastroduodenal tissue (p<0.05). CONCLUSION: In this study which was done with a restricted patient group, our results revealed that apoptosis induced by Fas expression in gastroduodenal suppressing carcinogenesis process plays an active role in gaining anti-apoptotic properties of cells (Tab. 4, Fig. 2, Ref. 27).

[Motivational orientation and depressive symptoms in the elderly]. / Orientation motivationnelle et symptomatologie dépressive chez la personne âgée.

This article is focused on motivation and depression in later life. For about 20 years, research on the motivation of elders has underlined the importance of the cognitive evaluation of life contexts, notably in terms of self-determination. This cognitive evaluation determines the motivational orientation for daily activities (notably the levels of intrinsic and extrinsic motivation). The purpose of this research was specifically to study the relationships between the existence of four types of motivation (intrinsic, self-determined extrinsic, nonself-determined extrinsic and amotivation) and the consequences for adaptation and well-being. The study, therefore, focused on the possible links between motivation and geriatric-depression level and explored the nature of this link. Forty persons aged 60 or over (31 women: 80.48+/-9.24; nine men: 80.56+/-9.48) who live in nursing homes (20 elderly) or in their own homes (20 elderly) were enrolled. Elderly persons were assessed with specific and standardized tools: the Elderly Motivation Scale (EMS, in the French version: EMPA) and the Geriatric Depression Scale (GDS). For the statistical analyses of the results, correlations and Mann-Whitney test were used. We found that in elderly people, the motivational styles (the four types of motivation) can be reliably measured and are related to geriatric depression. First, significant positive links were noticed between intrinsic motivation and depression scores and between self-determined extrinsic motivation and depression scores. Conversely, significant negative links were noticed between nonself-determined extrinsic motivation and depression scores and between amotivation and depression scores. The most self-determined elders presented low-depression levels, whereas the more nonself-determined elders showed high-depression levels. Moreover, motivational styles significantly differed in the two groups (depressive or not depressive). The most depressive elders showed significantly lower-intrinsic and self-determined motivation levels. Our results support the hypothesis that motivational styles are related to important aspects (adaptation, well-being and depression) of the life of elderly people. Self-determination theory appears of high interest in research on aging and especially on the determinants of well-being in the elders.

Helicobacter pylori-associated atrophic gastritis and carotid intima-media thickness: is there a link?

Chronic infections are associated with cardiovascular diseases. Helicobacter pylori-induced chronic active gastritis results in atrophic gastritis. In this study, we attempted to determine carotid intima-media thickness in patients with and individuals without H. pylori-induced atrophic gastritis. Oesophagogastroduodenoscopy was performed on 123 patients for various reasons. Helicobacter pylori were considered positive when histological examination and rapid urease test showed H. pylori. Helicobacter pylori-positive cases were divided into two groups, namely atrophic gastritis and non-atrophic gastritis. Of 123 patients, 92 patients had H. pylori-positive non-atrophic gastritis and 31 had H. pylori-positive atrophic gastritis. There was no significant difference in carotid intima-media thickness between the two groups. Carotid intima-media thickness is not associated with H. pylori-induced atrophic gastritis.

The relationship between erythrocyte superoxide dismutase activity and plasma levels of some trace elements (Al, Cu, Zn) of dialysis patients.

1. The effect of erythropoietin and some trace elements on superoxide dismutase (SOD) activity of dialysis patients have been studied. 2. SOD activity of dialysis patients was found to be decreased. 3. The effect of erythropoietin on SOD activity was not found in vitro. 4. Plasma and erythrocyte aluminum increased in dialysis patients, but no significant change in plasma copper was found. 5. Plasma zinc levels of dialysis patients were found to be decreased. 6. These results suggest that inhibition of erythrocyte SOD activity of dialysis patients may contribute to their anemia.
