Purpose: To report outcomes in hepatocellular carcinoma (HCC) patients with lobar and segmental vascular invasion treated with resin Yttrium-90 transarterial radioembolization (Y90-TARE) with single-compartment MIRD (Medical Internal Radiation Dose) model.
Materials And Methods: This was a retrospective IRB approved study of patients with a diagnosis of HCC with vascular invasion undergoing resin Y90-TARE from 2014 to 2022 (n = 61). Patients with Body Surface Area dosimetry (n = 20), main portal vein invasion (n = 6) and patients with an ECOG of > 2 were excluded (n = 1) with a final cohort of 34 patients.
Deletion of the long q arm of chromosome 22 (22qDEL) is the most frequently identified recurrent somatic copy number alteration (SCNA) observed in papillary thyroid carcinoma (PTC). Since its role in PTC is not fully understood, we conducted a pooled analysis of genomic characteristics and clinical correlates in 1094 primary tumors from four published PTC genomic studies. The majority of PTC with 22qDEL exhibited arm-level loss of heterozygosity (86%); nearly all PTC with 22qDEL had losses in 22q12 and 13, which together constitute 70% of the q arm.

Preclinical models of genetic risk for schizophrenia have shown reduced synaptic transmission from auditory thalamus to primary auditory cortex, which may represent a correlate of auditory disturbances such as hallucinations. Human neuroimaging studies, however, have found a generalized increase in resting state functional connectivity (RSFC) between whole thalamus and sensorimotor cortex in people with schizophrenia (PSZ).

The causes of this mismatch and opportunities for improvement are explored by the APDR Procedural Competency of Graduating DR Residents Task Force.
Materials And Methods: The APDR convened a task force consisting of diverse broad stakeholder viewpoints, drawing from organized radiology, academic and private practices.
Background And Objectives: In preparation for future clinical trials involving individuals with Alzheimer disease (AD), mild cognitive impairment (MCI), and dementia, it is important to ascertain the widespread impact of symptoms from the direct perspectives of patients and caregivers. In this study, we performed cross-sectional surveys using large-scale patient and caregiver data to identify the prevalence and average impact of symptoms and symptomatic themes experienced by adults with AD, MCI, and dementia. Subsequent analyses were used to determine which demographic and disease-specific factors are associated with more severe disease.
