The advance of high resolution digital scans of pathology slides allowed development of computer based image analysis algorithms that may help pathologists in IHC stains quantification. While very promising, these methods require further refinement before they are implemented in routine clinical setting. Particularly critical is to evaluate algorithm performance in a setting similar to current clinical practice. In this article, we present a pilot study that evaluates the use of a computerized cell quantification method in the clinical estimation of CD3 positive (CD3+) T cells in follicular lymphoma (FL)...

BACKGROUND: The new proposed classification for pancreaticobiliary cytology has advocated the use of carcinoembryonic antigen (CEA) analysis of cyst fluid as an ancillary diagnostic tool for the determination of mucinous neoplasms in pancreatic cyst aspirates. We aimed to investigate the effect of CEA cyst fluid analysis on cases primarily called negative or nondiagnostic and on the sensitivity and specificity of the method. METHODS: We retrospectively identified and collected all pancreatic cyst aspirates from 2010 to 2014 at Mayo Clinic, Jacksonville, Florida, along with available corresponding surgical diagnoses...

BACKGROUND: Evaluation of the nuclear to cytoplasmic ratio is commonly used for assessment of the presence of malignancy and for grading and typing of malignant neoplasms. Despite its widespread usage, little information exists regarding the accuracy and reproducibility of non-automated assessment. METHODS: Forty-seven cells obtained from Papanicolaou stained urine cytologies were assessed by quantitative image analysis for nuclear area and cell area. The nuclear/cytoplasmic ratio was calculated...

Jessica Barretta, Li Sub
Joint models for longitudinal and time-to-event data are particularly relevant to many clinical studies where longitudinal biomarkers could be highly associated with a time-to-event outcome. A cutting-edge research direction in this area is dynamic predictions of patient prognosis (e.g., survival probabilities) given all available biomarker information, recently boosted by the stratified/personalized medicine initiative. As these dynamic predictions are individualized, flexible models are desirable in order to appropriately characterize each individual longitudinal trajectory...

T K Padma Shri, N Sriraam
This paper presents a novel ranking method to select spectral entropy (SE) features that discriminate alcoholic and control visual event-related potentials (ERP'S) in gamma sub-band (30-55 Hz) derived from a 64-channel electroencephalogram (EEG) recording. The ranking is based on a t test statistic that rejects the null hypothesis that the group means of SE values in alcoholics and controls are identical. The SE features with high ranks are indicative of maximal separation between their group means. Various sizes of top ranked feature subsets are evaluated by applying principal component analysis (PCA) and k-nearest neighbor (k-NN) classification...

: Background and Hypotheses: The growing number of medical television series and the increasing amount of time people spend watching TV will have an influence on what they expect from their treatment in a hospital. We suspect that reality as presented in the media and the actual reality of hospitals are not always conceived of as two different worlds. Many medical TV shows present dramatic, life-threatening operations much more often than they occur in reality. Patients who frequently watch such shows might be induced to believe that even routine operations are often dangerous, which could result in higher levels of fear before such an operation...

INTRODUCTION: The outcomes of patients who fail their kidney transplant and return to dialysis (RTD) has not been investigated in a nationally representative sample. We hypothesized that variations in management of transplant chronic kidney disease stage 5 leading to kidney allograft failure (KAF) and RTD, such as access, nutrition, timing of dialysis, and anemia management predict long-term survival. METHODS: We used an incident cohort of patients from the United States Renal Data System who initiated hemodialysis between January 1, 2003 and December 31, 2008, after KAF...

BACKGROUND: Common carotid artery and internal carotid artery intima-media thicknesses (IMT) are associated with coronary heart disease (CHD) and increase with age. Using age, sex, and race/ethnicity IMT percentiles may improve CHD prediction when added to Framingham risk factors and coronary artery calcium score. We study these possibilities in the Multi-Ethnic Study of Atherosclerosis (MESA), a multi-ethnic cohort of whites, Chinese, blacks, and Hispanics. METHODS AND RESULTS: IMT data were acquired in the age range 45 to 84 years...

BACKGROUND: Patients with hallux valgus present a variety of symptoms that may be related to the type of deformity. Weightbearing affects the deformities, and the evaluation of the load response of tarsal bones has been mainly performed using two-dimensional plane radiography. The purpose of this study was to investigate and compare structural changes in the medial foot arch between patients with hallux valgus and normal controls using a computer image analysis technique and weightbearing computed tomography data...

OBJECTIVE: Prolactinomas are the most common functional hormone-producing pituitary lesions, accounting for 30-40% of all pituitary tumors, while in autopsy series their incidence reaches 50%. However, patients with prolactinoma had a higher recurrence percentage and rate than patients with acromegaly or Cushing's disease. Furthermore, prolactinomas have the highest rate of recurrence post-surgery as compared with other pituitary adenomas. At present, this behavior of prolactinoma is largely unexplained, but may be related to definition of cure, or to more frequent microscopic tumor infiltration into normal pituitary tissue, which is not removed at surgery...
