Limited utility of structural MRI to identify the epileptogenic zone in young children with tuberous sclerosis.

Background And Purpose: The success of epilepsy surgery in children with tuberous sclerosis complex (TSC) hinges on identification of the epileptogenic zone (EZ). We studied structural MRI markers of epileptogenic lesions in young children with TSC.

Methods: We included 26 children with TSC who underwent epilepsy surgery before the age of 3 years at five sites, with 12 months or more follow-up.

Multilevel Analysis of Individual and Neighborhood Characteristics Associated with Viral Suppression Among Adults with HIV in Rio de Janeiro, Brazil.

Understanding the impact of neighborhood context on viral suppression outcomes may help explain health disparities and identify future interventions. We assessed the relationship between individual characteristics, neighborhood socioeconomic context, and viral suppression using multilevel logistic regression models. Adults with HIV initiating antiretroviral therapy (ART) between 2000 and 2017, who resided in Rio de Janeiro and had an HIV-1 RNA level (viral load) measured 90-270 days after ART initiation were included.

A sentinel COVID-19 case in Houston, Texas: Informing frontline emergency department screening and preparedness.

In December 2019, a cluster of severe pneumonia cases of unknown cause was reported in Wuhan, Hubei province, China. A novel strain of coronavirus belonging to the same family of viruses that cause severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) was identified. In February 2020, cases began being identified in the United States.

Ongoing Secondary Degeneration of the Limbic System in Patients With Ischemic Stroke: A Longitudinal MRI Study.

Ongoing post-stroke structural degeneration and neuronal loss preceding neuropsychological symptoms such as cognitive decline and depression are poorly understood. Various substructures of the limbic system have been linked to cognitive impairment. In this longitudinal study, we investigated the post-stroke macro- and micro-structural integrity of the limbic system using structural and diffusion tensor magnetic resonance imaging.

Sex Differences in Adipose Tissue CD8 T Cells and Regulatory T Cells in Middle-Aged Mice.

The prevalence of cardiovascular disease has increased among middle-aged women in the United States, yet has declined in middle-aged men. In experimental stroke, middle-aged females have larger strokes and greater inflammation than age-matched males or younger females. The mechanism underlying this shift from an "ischemia-protected" to an "ischemia-sensitive" phenotype in aging females is unknown.
