This study examined differences in scoring patterns among those diagnosed with Alzheimer's dementia and vascular dementia on the clock-drawing test. Archival clock drawing data was retrieved on 279 patients presenting at a county hospital-based memory clinic. Analysis of drawings was based on frequency of qualitative errors, as well as an overall quantitative score. Mean comparisons found those patients with Alzheimer's dementia to perform worse on both quantitative and qualitative scoring measures. However, Pearson's chi-squared test revealed a significantly higher rate of spacing errors among subjects with vascular dementia. Such lends support to my hypothesis that impaired executive functioning in vascular dementia patients would lead to poor qualitative performance. Logistic regression found significant predictive ability for the qualitative criteria in diagnosis (χ2 = 25.49, p < .001), particularly the rate of omission (z = 8.96, p = .003) and addition errors (z = 7.58, p = .006). Such findings hold important implications for the use of qualitative criteria in cognitive screening assessments.

Background Colorectal cancer (CRC) is one of the most common cancers with high morbidity and mortality among both genders and yet it carries a better prognosis when detected early. Colorectal cancer screening using faecal occult blood test (FOBT) is proven to be cost-effective, however worldwide FOBT uptake rate is suboptimal which directly affects the cost-effectiveness of the screening program. Identifying those factors that influence the uptake of colorectal cancer screening using FOBT will allow implementation of relevant measures when planning a population based screening program. Methods A structured electronic search using PubMed and Medline was conducted in order to identify studies that included factors influencing the uptake of CRC screening by using FOBT. Qualities of included studies were assessed by quality assessment checklist STROBE. Results Factors that contributed to the low uptake rate of CRC screening by FOBT were identified and summarized. They were broadly divided into 3 groups. Demographic factors: age, gender, social economic status, insurance status and education, for ethnicity, employment status and obesity further studies in the future may be needed. Subject factors: subject’s attitudes and knowledge towards CRC screening, type of FOBT screening, health concerned behavior, frequency of clinical visit and physiciancomment. Provider factors: health care system factor and physicians’ factors. Conclusion Different factors, in particular those factors that were associated with low FOBT uptake rate in CRC screening, were reviewed and summarized in this paper. With the continuous effort from worldwide as well as local investigators, timely measures can be implemented to tackle this deathly disease and to ensure cost effectiveness of a screening program. / published_or_final_version / Public Health / Master / Master of Public Health
