METHODS： Hepatitis B surface antigen （HBsAg）, anti-HCV and anti-human immunodeficiency virus （HIV） seroprevalence, HBV DNA, HCV RNA and HCV genotyping among soldiers from Turkey （group Ⅰ ）, civil blood donors from Northern Cyprus （group Ⅱ ）, and soldier candidates from Northern Cyprus （group Ⅲ） were studied and compared to one another. In total, 17 545 cases （13 546 males and 3999 females with a mean age of 34.5 ± 10.3 year, group Ⅰ = 11234, group Ⅱ = 5057, and group Ⅲ = 1254） were included into the study. RESULTS： Among all cases, HBsAg positivity rates were 2.46%, anti-HCV was 0.46% and anti-HIV was 0.00%. HBV DNA was 2.25%, HCV RNA was 0.33% in all groups. HBsAg positivity rates were 2.16% in group Ⅰ, 3.00% in group Ⅱ and 2.71% in group Ⅲ. There was a significant difference between group Ⅰ and group Ⅱ （χ^2= 6.11, P = 0.047 〈 0.05）. Anti-HCV positivity rates were 0.45% in group Ⅰ, 0.45% in group Ⅱ, and 0.56% in group Ⅲ. Genotypes of HCV were 1b and 1a in group Ⅰ, 1b, 1a and 2 in group Ⅱ, and tb, 1a in group Ⅲ. HBsAg carrier rates were 2.20% in females and 2.53% in males. Anti-HCV prevalence was 0.38% in females and 0.48% in males. HBsAg positivity rates were 2.53% in individuals younger than 50, and 1.47% in older than 50. There was a significant difference between the two groups （χ^2 =23.48, P = 0.001） CONCLUSION： Prevalences of HBsAg, HCV and HIV infections in Northern Cyprus population are similar to those of Turkey.展开更多

Moreover dependence between apoptosis and HBV-DNA or HCV-RNA levels was studied. METHODS:Eighty-six persons were included into study:34 healthy HBsAg carders,33 patients with chronic HBV infecl^on and 19 patients with chronic HCV infection.Serum levels of sFas/sFasL were measured by ELISA assay.HBV-DNA and HCV-RNA were measured by RT-PCR assay.Levels of sFas/sFasL were determined before and 2 and 12 wk after therapy in patients with chronic hepatitis B and C infection. HBV-DNA or HCV-RNA was detected before treatment and 6 mo after treatment. RESULTS:Twenty-four (71%) healthy HBsAg carders showed HBV-DNA over 10~5/mL,which was comparable to the patients with chronic hepatitis B.independently from HBV-DNA levels, the concentration of sFas among healthy HBsAg carders was comparable to healthy persons.Among patients with chronic hepatitis B and C,the concentration of sFas was significantly higher in comparison to healthy HBsAg carriers and healthy persons.In chronic hepatitis B patients the concentration of sFas was decreased during lamivudine treatment.Among chronic hepatitis C patients the concentration of sFas was increased during IFN alpha and ribavirin treatment,sFasL was not detected in control group.Furbhermore sFasL occurred more frequently in chronic hepatitis C patients in comparison to chronic hepatitis B patients. CONCLUSION:There are no correlations between apoptosis and HBV-DNA levels.However ther is an association between apoptosis and activity of inflammation in patients with chronic HBV infection.Apoptosis can be increased in patients with chronic hepatitis C by effective treatment which may be a result of apoptosis stimulation by IFN-α.展开更多

Common etiological factors include autoimmune diseases, ma-lignancy, and pregnancy. We report two cases of AHA in solid cancer. The first case is a 63-year-old man who developed peritoneal and intestinal bleeding after gastrectomy for gastric cancer. He was diagnosed with AHA, and was treated with prednisone, followed by cyclophosphamide. In the second case, a 68-year-old man developed a subcutaneous hemorrhage. He was diagnosed with AHA in hepatocellular carcinoma on CT imaging, and treated with rituximab alone. Hemostasis was achieved for both patients without bypassing agents as the amount of inhibitors was reduced and eradicated. However, both patients died within 1 yeardue to cancer progression. Successful treatment for AHA in solid cancer can be diffcult because treatment of the underlying malignancy is also required.展开更多

In total, 4422 screening participants(32%) completed the questionnaire, which consisted of the Hospital Anxiety and Depression Scale and the SF-12, a generic health-related quality of life(HRQOL) measurement, when invited to screening and one year after the invitation. A control group of 7650 individuals was invited to complete the questionnaire only, at baseline and one year after, and 1911(25%) completed the questionnaires.RESULTS Receiving a positive or negative screening result and participating in the two different screening modalities did not cause clinically relevant mean changes in anxiety, depression or HRQOL after one year. FS screening, but not FIT, was associated with an increased probability of being an anxiety case(score ≥ 8) at the one-year follow-up(5.6% of FS participants transitioned from being not anxious to anxious, while 3.0% experienced the reverse). This increase was moderately significantly different from the changes in the control group(in which the corresponding numbers were 4.8% and 4.5%, respectively), P = 0.06. CONCLUSION Most individuals do not experience psychological effects of CRC screening participation after one year, while FS participation is associated with increased anxiety for a smaller group.展开更多

Zn deficiency caused by malnutrition and foods with low bioavailability, aging, certain diseases, or deregulated homeostasis is a far more common risk to human health than intoxication. Higher dose of Zn should be limited to short-term use because of an increased risk of gastrointestinal adverse effects, copper deficiency, anemia, and genitourinary complications. This review has detonated the literature on the spectrum of health effects of Zn status, ranging from symptoms of Zn deficiency to excess exposure.展开更多
