Multimarker approach, including biomarkers of oxidative stress, dyslipidemia and inflammation, could be of benefit in identifying patients with diabetes being at high risk of fatty liver disease.

Background:Recent studies hypothesize that dyslipidemia can predict glycated hemoglobin (HbA1c) and could be important contributing factor to the pathogenesis of type 2 diabetes mellitus (DM2). Therefore, we aimed to evaluate the influence of lipid parameters on long-term glycemic control in DM2.Materials and Methods:A total of 275 sedentary DM2 (mean [±standard deviation] age 60.6 [±10.0] years) who volunteered to participate in this cross-sectional study were enrolled. Anthropometric (body weight, body hight, and waist circumference), biochemical parameters (fasting glucose, HbA1c, lipid parameters, creatinine), as well as blood pressure were obtained.Results:Total cholesterol (odds ratio [OR] =1.30, 95% confidence interval [CI] [1.02–1.66], P = 0.032), triglycerides (OR = 1.34, 95% CI (1.07–1.67), P = 0.010), and low density lipoprotein cholesterol (OR = 1.42, 95% CI [1.10–1.83], P = 0.006) were the independent predictors of higher HBA1c, and as they increased by 1 mmol/L each, probabilities of higher HBA1c increased by 30%, 34%, and 42%, respectively. Low level of high-density lipoprotein cholesterol (HDL-c) was found to be the independent predictor of higher HBA1c (OR = 0.44, 95% CI [0.20–0.67], P = 0.039), and increase in HDL-c by 1 mmol/L, reduced the probability of higher HBA1c by 56%.Conclusion:Unfavorable lipid profile can predict HbA1c level in DM2 patients. Early diagnosis of dyslipidemia, as well as its monitoring and maintaining good lipids control can be used as a preventive measure for optimal long-term glycemic control.

Laryngeal cancer is the most common head and neck cancer. There might be many risk factors for laryngeal cancer. Smoking, especially cigarette smoking and alcohol are indisputable risk factors. The authors of this paper assessed the presumed risk factors in order to identify possible aetiological agents of the disease. A hospital-based case-control study was conducted. The study group consisted of 108 histologically verified laryngeal cancer patients and 108 hospital controls matched by sex, age (±3 years) and place of residence. Laryngeal cancer patients and controls were interviewed during their hospital stay using a structured questionnaire. According to multiple logistic regression analysis six variables were independently related to laryngeal cancer: hard liquor consumption (Odd Ratio /OR/=2.93, Confidence Interval /CI/ 95 % = 1.17 to 7.31), consumption more than 2 alcoholic drinks per day (OR=4.96, CI 95 % = 2.04 to12.04), cigarette smoking for more than 40 years (OR=4.32, CI 95 % = 1.69 to 11.06), smoking more than 30 cigarettes per day (OR=4.24, CI 95 % = 1.75 to 10.27), coffee consumption more than 5 cups per day (OR=4.52, CI 95 % = 1.01 to 20.12) and carbonated beverage consumption (OR=0.38, CI 95 %= 0.16 to 0.92). The great majority of laryngeal cancers could be prevented by eliminating tobacco smoking and alcohol consumption.

The purposes of the present study were to determine the distribution of cells producing cytokines: tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) in different morphological sections of tonsils in patients with tonsillar hypertrophy (TH) and recurrent tonsillitis (RT), to analyze the level of production of these cytokines in TH and RT and evaluate the potential of peripheral blood lymphocytes for production of interferon-γ (IFN-γ) and interleukin 4 (IL-4). Analyzed materials consisted of the tonsils after tonsillectomy and blood taken from patients right before tonsillectomy (study group) and blood taken from healthy donors (control group).We used histological and immunohistochemical method, morphometric methods for the quantification of TNF-α and IL- 6 producing cells and immunological methods for determining the concentration of IFN-γ and IL-4. Most of TNF-α producing cells are settled in the subepithelial region (55%). Numerical density of TNF-α producing cells in the crypt epithelium, subepithelial and interfollicular region was significantly higher in RT compared with TH. The concentration of IFN-γ is three times higher in RT then in TH. After the stimulation of peripheral blood lymphocytes in culture there was no significant increase in concentrations of IL- 4. The index of stimulation of IFN-γ was the highest in the RT, and of IL- 4 in TH. The production of Th1-type cytokines (TNF-α and IFN-γ) is higher in RT compared with TH. In both forms of tonsillitis, production of Th1-type cytokines is higher in relation to the production of Th2-type cytokines (IL-6 and IL-4).

The purpose of the present study was to examine the expression of CD105 among patients with supraglottic laryngeal cancer and to assess the clinical relevance of CD105-assessed MVD. A total of 40 patients with supraglottic squamous cell carcinomas (SCCs) were included in the present study. Surgical specimens were immunostained for CD105 and MVD was calculated at 400x magnification. The rounded mean value of the vessel count in four fields for each case was used as the final MVD value. The mean MVD value assessed by CD105 in considered supraglottic SCCs was 13.5 (SD = 3.97). High MVD was significantly correlated with advanced (III and IV) clinical stage (Mann-Whitney U test P = 0.01) and malignancy recurrence presence/absence (Mann-Whitney U test P = 0.023). Spearman's rank correlation test showed significant correlation between high CD105-assessed MVD and pN+ category (rho = 0.337, P = 0.033), advanced Stage (III and IV) (rho = 0.402, P = 0.01) and developed locoregional recurrence (rho = 0.395, P = 0.012). The logistic regression showed that a high CD105+ MVD was the only independent marker of tumor recurrence (P = 0.029; odds ratio, 6.64; 95% CI, 1.218-36.152). The average MVD was significantly higher in patients with advanced TNM stage and in patients with locoregional recurrence of disease, suggesting that angiogenesis is closely related with clinical aggressiveness of tumor. CD105-assessed MVD in supraglottic laryngeal SSCs may identify patients at risk of recurrence of disease.
