Abstract

An exceptionally low purity microwave noise levels from a microwave oscillator that uses a conventional air-dielectric cavity resonator as a frequency discriminator is reported. This approach is to increase the discriminator's intrinsic signal-to-noise ratio by use of a high-power carrier signal to interrogate an optimally coupled cavity, while the high-level of the carrier is suppressed before the phase detector.

241. Apathy Endorsement in Late Life Depression is Associated with Executive Dysfunction

Author

Abstract

Executive function deficits are prevalent in late life depression (LLD) and linked to poorer outcomes. Little is known about the underlying factors that contribute to greater executive dysfunction in LLD, yet understanding these factors is critical for identifying new intervention targets to reduce the public health burden associated with depression and cognitive impairment in late life. Although negative affect has traditionally been the focus of scientific inquiry related to depressive symptomatology, emerging work is highlighting associations of Positive Valence System (PVS) dysfunction with depression. PVS functions are characterized by positive affect and approach behaviors toward potentially rewarding stimuli and are associated with better cognitive control in non-depressed adults. PVS deficits such as apathy are common in LLD and present as diminished goal-directed behavior, decreased interest in activities, and flattened affect. One prior study found that greater apathy was significantly associated with lower executive function performance in LLD, but more work is needed to characterize associations between PVS functions and executive dysfunction, including impairment rates. To this end, we examined associations between apathy endorsement in LLD and 1) performance on executive function measures and 2) rates of executive function impairment.

Abstract

Predicting progression of mild cognitive impairment (MCI) to Alzheimer's disease (AD) is clinically important. In this study, we propose a dual-model radiomic analysis with multivariate Cox proportional hazards regression models to investigate promising risk factors associated with MCI conversion to AD. T1 structural magnetic resonance imaging (MRI) and 18F-Fluorodeoxyglucose (FDG) positron emission tomography (PET) data, from the AD Neuroimaging Initiative database, were collected from 131 patients with MCI who converted to AD within 3 years and 132 patients with MCI without conversion within 3 years. These subjects were randomly partition into 70% training dataset and 30% test dataset with multiple times. We fused MRI and PET images by wavelet method. In a subset of subjects, a group comparison was performed using a two-sample t-test to determine regions of interest (ROIs) associated with MCI conversion. 172 radiomic features from ROIs for each individual were established using a published radiomics tool. Finally, L1-penalized Cox model was constructed and Harrell's C index (C-index) was used to evaluate prediction accuracy of the model. To evaluate the efficacy of our proposed method, we used a same analysis framework to evaluate MRI and PET data separately. We constructed prognostic Cox models with: clinical data, MRI images, PET images, fused MRI/PET images, and clinical variables and fused MRI/PET images in combination. The experimental results showed that captured ROIs significantly associated with conversion to AD, such as gray matter atrophy in the bilateral hippocampus and hypometabolism in the temporoparietal cortex. Imaging model (MRI/PET/fused) provided significant enhancement in prediction of conversion compared to clinical models, especially the fused-modality Cox model. Moreover, the combination of fused-modality imaging and clinical variables resulted in the greatest accuracy of prediction. The average C-index for the clinical/MRI/PET/fused/combined model in the test dataset was 0.69, 0.73, 0.73 and 0.75, and 0.78, respectively. These results suggested that a combination of radiomic analysis and Cox model analyses could be used successfully in survival analysis and may be powerful tools for personalized precision medicine patients with potential to undergo conversion from MCI to AD.
