Studies in SIV-infected macaques show that the virus reservoir is particularly refractory to conventional suppressive antiretroviral therapy (ART). We posit that optimized ART regimens designed to have robust penetration in tissue reservoirs and long-lasting antiviral activity may be advantageous for HIV or SIV remission. Here we treat macaques infected with RT-SHIV with oral emtricitabine/tenofovir alafenamide and long-acting cabotegravir/rilpivirine without (n = 4) or with (n = 4) the immune activator vesatolimod after the initial onset of viremia.

However, its application to improve post-interventional vascular remodeling remains underexplored. Here we find that MetR protects from arterial intimal hyperplasia in a focal stenosis model and pathologic vascular remodeling following vein graft surgery in male mice.

The gut microbiome may be a factor in determining weight trajectory, but examination has been limited by a lack of longitudinal studies with robust microbiome sequencing. This study aimed to describe changes in the microbiome and associations with weight outcomes more than 2 years post surgery.

The interplay of social, individual, and biological factors makes this a complex process in the psychiatry of people with intellectual disability (PwID).
Aim: Review of outcome measures which are validated in PwID.
Epilepsy care generates multiple sources of high-dimensional data, including clinical, imaging, electroencephalographic, genomic, and neuropsychological information, that are collected routinely to establish the diagnosis and guide management. Thanks to high-performance computing, sophisticated graphics processing units, and advanced analytics, we are now on the cusp of being able to use these data to significantly improve individualized care for people with epilepsy. Despite this, many clinicians, health care providers, and people with epilepsy are apprehensive about implementing Big Data and accompanying technologies such as artificial intelligence (AI).

Purpose Of Review: Recent literature suggests a potential causal link between metabolic bariatric surgery (MBS) and an increased risk of eating disorders. However, the available literature offers unclear results regarding the definition of eating problems among MBS patients, their potential impact on weight outcomes, and the efficacy of adjunctive treatment.
Recent Findings: Although eating disorders may be rare phenomena after surgery, disordered eating behaviors are more common and tend to be more consistently associated with suboptimal weight loss.
The rationale of this study stems from the concern of a radiation-induced accident or terrorist-mediated nuclear attack resulting in large populations of people exposed to nonlethal radiation doses or after a course of definitive radiation therapy which could substantially increase the risk for cancer induction after exposure. Currently, there are no safe and effective interventions to reduce this increased cancer risk to humans. We have tested the hypothesis that the mTOR inhibitor, rapamycin, administered in the diet of mice would reduce or delay radiation-induced cancer when given after radiation exposure.

This report provides a synthesis of the deliberations from the Special-purpose Committee. We discuss the arguments for and against the proposed solution to the problems that have arisen regarding the nomenclature of fungi described in multiple morphs using the same epithet.

Post-traumatic headache (PTH) is the most common symptom reported following mild TBI and can persist for several years. However, the current International Classification of Headache Disorders lacks phenotypic characterization for this specific headache disorder.

Yet, the impact of SAAR on skeletal muscle remains largely unexplored. Here we demonstrate that one week of SAAR in sedentary, young, male mice increases endurance exercise capacity.

During aging, levels of NAD can decrease by up to 50% in some tissues, the repletion of which provides a range of health benefits in both mice and humans. Whether or not the NAD precursor nicotinamide mononucleotide (NMN) extends lifespan in mammals is not known.

To date, only one of the 244 drugs in clinical trials for the treatment of neurodegenerative diseases has been approved in the past decade, indicating a failure rate of 99.6%.

The International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group of experts in epilepsy, people with epilepsy, and their representatives to develop minimum sets of standardized outcomes and outcome measurement methods for clinical practice. Using modified Delphi consensus methods with consecutive rounds of online voting over 12 months, a core set of outcomes and corresponding measurement tool packages to capture the outcomes were identified for infants, children, and adolescents with epilepsy.

OH_Est produced a 15% increase (p = 0.0001) in median lifespan in males but led to a significant (7%) decline in female lifespan.
