OBJECTIVE: ObjectiveaaWe evaluated the distribution of alpha-2A adrenergic receptor (ADRA2A) and catechol-o-methyltransferase (COMT) single nucleotide polymorphisms (SNPs) among ADHD subtypes and other homogeneous patient populations including treatment-resistant cases and patients with high symptom severity. METHODS: Methodsaa121 ADHD patients aged 6-18 years were included in the study. Diagnosis and subtypes designation were confirmed using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) and symptoms were evaluated using the Conners' Parent (CPRS) and Teacher Rating Scales (CTRS). The response to methylphenidate was assessed objectively using the Clinical Global Impression-Severity Scale (CGI-S) and Global Assessment of Functioning Scale (GAS) as well as the Continuous Performance (CPT) and Trail Making tests (TMT-A, B). Patients were genotyped for ADRA2A (rs1800544) and COMT (rs4680) SNPs by PCR/RFLP and compared to a gender-matched control group. RESULTS: Although there was no association of COMT (rs4680) SNP with symptoms or diagnosis, the ADRA2A polymorphism, low socioeconomic status (SES), and comorbid psychiatric diagnosis were all associated with poor response to methylphenidate in logistic regression analysis. CONCLUSION: Clinicians may consider adjuvant strategies when these negative factors are present to increase the success of tailored ADHD treatments in the future.

PURPOSE: Involvement of human kallikreins (hKs) in human cancers has been reported and several hKs are promising biomarkers of various cancers. The aim of this study was to evaluate the prognostic significance of hK11 expression in patients with non-metastatic non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: The study included 44 patients with NSCLC. hK11 expression was determined by immunohistochemical staining. RESULTS: The estimation of disease-free and overall survival by Kaplan-Meier was 11 months and 17 months, respectively. The estimation of overall survival by Kaplan-Meier was significantly higher in patients with hK11 strongly positive (2+) than in those with hK11 weakly positive (1+) (20 months vs. 11 months, p=0.032). Although not statistically different, the estimation of disease-free survival by Kaplan-Meier was higher in patients with hK11 strongly positive (2+) than in those with hK11 weakly positive (1+) (12 months vs. 9 months, p=0.113). Multivariate Cox regression analysis showed that the overall survival rates were significantly associated with response to chemoradiotherapy and the degree of staining with hK11. CONCLUSION: The stronger hK11 expression in NSCLC appears to be associated with better survival rates. hK11 may be a prognostic biomarker of NSCLC.

Cardiovascular disease (CVD) is still the major cause of the morbidity and mortality in hemodialysis (HD) patients. The characteristics of major arterial changes, atherosclerosis and related risk factors in HD patients remain unclear. We aimed to evaluate the atherosclerotic process in asymptomatic HD patients and healthy volunteers, and to determine the association between the risk factor (s) and the atherosclerotic process in these groups. 92 HD patients (female: 43, male: 49) and 62 age and sex matched healthy volunteers (female: 27, male: 35) were enrolled in this study. Diabetics, smokers, and patients with symptomatic CVD were excluded. The right and left carotid intima-media thicknesses (CIMTs) were measured and plaque structures were studied by B-mode ultrasound. The mean CIMT in patients and control group were 0.79 +/- 0.16 mm and 0.54 +/- 0.09 mm, respectively. Mean CIMT in HD patients was thicker (p < 0.001) and the presence ratio of plaque was higher in patients group (n=38, %61.2 vs n=9, %17.3) (p < 0.001). Calcified type of plaque was more frequent in HD patients than control group. Age (r=0.48, p < 0.001), left ventricular mass (r=0.42, p < 0.05), and homocysteine (r=0.46, p < 0.01), mean hematocrit (r=-0.36, p < 0.05), plasma CRP (r=0.50, p < 0.001), ESR (r=0.43, p < 0.01) and albumin (r= -0.34, p < 0.05) levels were correlated with the CIMT measurements and plaque presence, significantly. -CIMT as an atherosclerotic process indicator is thicker in asymptomatic HD patients than healthy subjects. We concluded that in addition to various classical risk factors, uremic environment may also contribute to acceleration of the atherosclerotic process.
