Researchers Determine Predicting Factors Of Positive Lung Cancer Diagnoses In Chest Radiographs
A study published in the June 2009 issue of the Journal of Thoracic Oncology determined several predictors of a positive lung cancer diagnosis after having an abnormal chest x-ray. Dr. Martin Carl Tammemagi of Brock University in Ontario and his team of US researchers examined the chest radiographs of 12,314 individuals obtained through the National Cancer Institute"s Prostate Lung Colorectal Ovarian Cancer Screening Trial (PLCO). They found that older age, lower education levels and a longer smoking history were all associated with a "true positive" diagnosis for lung cancer in those individuals with an abnormal screening chest radiograph.

Advanced Image Analysis Can Provide Better Risk Assessment In Hardening Of The Arteries
Ultrasound examination of the carotid artery is a patient-friendly and inexpensive method for assessing atherosclerosis and thereby predicting the risk of cardiovascular diseases. Peter Holdfeldt, who recently defended his doctoral thesis at Chalmers University of Technology in Sweden, has developed new analytical methods for ultrasound images that can provide more reliable and more exact assessments of atherosclerosis.

Rise In New Cases Of Alzheimer's And Dementia, Even In The 'Oldest Old'

M. Prince, None; J. Georges, None. Background: An accurate estimate of the numbers of individuals affected with dementia is essential. Previous collaborative work from Europe is based on studies performed 20 years ago. This current project aims to determine the prevalence of dementia in Europe based on up to date research findings and includes data from Eastern Europe. Methods: A systematic review followed by collaborative analysis of studies reporting the prevalence of dementia in Europe. Medline and Embase searches were performed using the search terms "Dementia / Prevalence / Incidence / Epidemiology" and/or "Alzheimer"s Disease / Vascular dementia, Lewy-body disease / Fronto-temporal dementia / Incidence / Prevalence / Epidemiology. A database of studies was compiled and those fulfilling predetermined quality criteria were invited to submit data for collaborative analysis. Age and sex specific prevalence"s were calculated using the total number of prevalence cases from all studies as the numerator and total population examined as the denominator. Results: A total of 194 articles were identified by the review and 26 studies met inclusion criteria to participate with raw data in the collaborative analysis. Calculated age specific prevalence rates for men confirmed previous findings with rates rising from 1.8% in the 65-69 years age range up to 30% in the over 90 years age group. For women confirmation of previous findings was also true for the 65 to 85 years age ranges with 5 year age specific rates rising from 1.5% to 30% respectively. Age specific prevalence rates were however higher than previously documented in the female oldest old age groups rising to over 50% in those over 95 years. Conclusions: Epidemiological studies of dementia prevalence in Europe continue to show constant rates in all age ranges with the female oldest old being the exception. Here estimates show a higher than previously reported prevalence in females. Niles Frantz Alzheimer"s Association
