In the present study, we proposed to evaluate the associations between folate and vitamin B12, with fasting plasma tHcy concentration in prostate cancer (PCa) patients. \u0000Methods: A case –control study was conducted with 40 newly patients with prostate cancer diagnosed with prostate cancer and 50 age matched healthy controls. Serum level of total homocysteine, folate and vitamin B12 were measured by enzyme conversion immunoassay and radioassay, respectively using the ARCHITECT system (both Abbott–Diagnostics Division). \u0000Results: The average rate of total PSA was 20.97 ng / ml (ranged between 8- 60 ng / ml). 53% of patients had a PSA≥20ng/ml. Histology confirmed that all patients accounted for prostatic adenocarcinoma with prognostic Gleason score that ranged between 7 and 8 . There are no significant differences between cases and controls about serum Hcy levels (adjusted OR = 0.160% CI = 0.832-1.031), folate levels (adjusted OR = 0.428% CI = 0.977-1.008) and vitamin B12 (adjusted OR = 0.103% CI = 0.992-1.001). \u0000Conclusion: In this study, the results show that homocysteine is not involved in prostate cancer. However, this study shows that the sporadic form is much more prevalent than familial one.

Mass screening has proven effectiveness by significantly reducing incidence and mortality. If optical colonoscopy is the reference exam, virtual colonoscopy is an alternative of choice. We evaluate its first-line position in screening, following technological progress. \u0000Methods: We used PubMed's electronic search data from 2010. Among the 100 most consulted articles, have been studied those in English-language and which looked at screening in the population at average risk aged between 50 and 75 years , asymptomatic and dealing with optical and virtual colonoscopy. Studies in the symptomatic, high-risk, or very high-risk population or for diagnostic purposes were excluded. \u0000Results: in the USA, studies confirm the trend towards a decrease in incidence and mortality by colorectal cancers, shifting from 56.7 per 100,000 and 23.6 deaths respectively in 1992 to 36.5 per 100,000 and 14 deaths in 2015, thanks to the means of screening including the endoscopy. Although optical colonoscopy is the standard exam, virtual colonoscopy, with a specificity of 90% and a sensitivity of 85%, is becoming more and more a first-line means of screening for colorectal cancers. \u0000Conclusion: Thus, first-line endoscopic screening has proved its effectiveness in reducing morbidity and mortality by this cancer. However, the virtual endoscopy chosen by the National Comprehensive Cancer Network as a means of screening will undoubtedly constitute a strategy for the future, particularly in developing countries.","PeriodicalId":397681,"journal":{"name":"Medical Technologies Journal","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126583389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work is to design a real-time customized keyboard to be used by a physically challenged person to speak to the outside world, for example, to enable a computer to read a story or a document, do gaming and exercise of nerves, etc., through eye features tracking \u0000Method: In a paralyzed person environment, the right-left, up-down eyeball movements act like a scroll and eye blink as a nod. The eye features are tracked using Support Vector Machines (SVMs). \u0000Results: A prototype keyboard is custom-designed to work with eye-blink detection and eyeball-movement tracking using Support Vector Machines (SVMs) and tested in a typical paralyzed person-environment under varied lighting conditions. Tests performed on male and female subjects of different ages showed results with a success rate of 92%. \u0000Conclusions: Since the system needs about 2 seconds to process one command, real-time use is not required. The efficiency can be improved through the use of a depth sensor camera, faster processor environment, or motion estimation.","PeriodicalId":397681,"journal":{"name":"Medical Technologies Journal","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124493816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
