Article Synopsis
  • Scientists are trying to figure out how to diagnose different types of blood disorders called MDS and MPN, which can be tricky because they have some similar features.
  • They looked at the DNA of patients with different types of these disorders to see how they are different and found specific gene mutations that can help identify each type.
  • The research shows that age and certain mutations can affect how well patients do, and this information can help doctors make better decisions about treatment.

Youth Engagement Synergy in Mental Health Legislation and Programming.

Child Adolesc Psychiatr Clin N Am

October 2024

Substance Abuse and Mental Health Services Administration, Center for Mental Health Services, 5600 Fishers Lane, Rockville, MD 20857, USA.

Youth engagement in implementing mental health legislation and programming is an intuitive best practice. However, well-intentioned efforts to work inclusively with youth are often perfunctory. Drawing from select community partnership models and insights from providers, public health advisors, and youth, we examine the typology, processes, and outcomes of youth engagement.

Endovascular vs Medical Management of Acute Basilar Artery Occlusion: A Secondary Analysis of a Randomized Clinical Trial.

JAMA Neurol

October 2024

Department of Neurology, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China.

Importance: In several randomized clinical trials, endovascular thrombectomy led to better functional outcomes than conventional treatment at 90 days poststroke in patients with acute basilar artery occlusion. However, the long-term clinical outcomes of these patients have not been well delineated.

Objective: To evaluate 1-year clinical outcomes in patients with acute basilar artery occlusion following endovascular thrombectomy vs control.

Article Synopsis
  • Chronological age is how many years someone has lived, while biological age shows how well their body is functioning, and this can vary even among people of the same age.
  • Scientists are trying to create ways to measure biological age in dogs by studying different dog breeds since they have different lifespans.
  • Research on dogs using special tests called methylation shows that it's challenging to find clear biological age markers, and we need to consider the differences among dog breeds to make better predictions.

Insulin and leptin oscillations license food-entrained browning and metabolic flexibility.

Cell Rep

Department of Medicine, Division of Digestive Diseases, University of Los Angeles, Los Angeles, CA, USA; Department of Developmental and Molecular Biology, Albert Einstein College of Medicine, Bronx, NY, USA; Department of Medicine, Albert Einstein College of Medicine, Bronx, NY, USA; Comprehensive Liver Research Center at UCLA, University of Los Angeles, Los Angeles, CA, USA. Electronic address:

Timed feeding drives adipose browning, although the integrative mechanisms for the same remain unclear. Here, we show that twice-a-night (TAN) feeding generates biphasic oscillations of circulating insulin and leptin, representing their entrainment by timed feeding. Insulin and leptin surges lead to marked cellular, functional, and metabolic remodeling of subcutaneous white adipose tissue (sWAT), resulting in increased energy expenditure.

BayesAge: A maximum likelihood algorithm to predict epigenetic age.

Front Bioinform

April 2024

Department of Molecular, Cell and Developmental Biology, University of Los Angeles, Los Angeles, CA, United States.

DNA methylation, specifically the formation of 5-methylcytosine at the C5 position of cytosine, undergoes reproducible changes as organisms age, establishing it as a significant biomarker in aging studies. Epigenetic clocks, which integrate methylation patterns to predict age, often employ linear models based on penalized regression, yet they encounter challenges in handling missing data, count-based bisulfite sequence data, and interpretation. To address these limitations, we introduce BayesAge, an extension of the scAge methodology originally designed for single-cell DNA methylation analysis.

Time-of-day significantly influences the severity and incidence of stroke. Evidence has emerged not only for circadian governance over stroke risk factors, but also for important determinants of clinical outcome. In this review, we provide a comprehensive overview of the interplay between chronobiology and cerebrovascular disease.

Neural complexity is increased after low doses of LSD, but not moderate to high doses of oral THC or methamphetamine.

Neuropsychopharmacology

June 2024

Department of Psychiatry and Behavioral Neuroscience, University of Chicago, 5841 S Maryland Ave, Chicago, IL, 60637, USA.

Neural complexity correlates with one's level of consciousness. During coma, anesthesia, and sleep, complexity is reduced. During altered states, including after lysergic acid diethylamide (LSD), complexity is increased.

Importance: The spring 2020 surge of COVID-19 unprecedentedly strained ventilator supply in New York City, with many hospitals nearly exhausting available ventilators and subsequently seriously considering enacting crisis standards of care and implementing New York State Ventilator Allocation Guidelines (NYVAG). However, there is little evidence as to how NYVAG would perform if implemented.

Objectives: To evaluate the performance and potential improvement of NYVAG during a surge of patients with respect to the length of rationing, overall mortality, and worsening health disparities.

Importance: Outcome prediction after endovascular treatment (EVT) for ischemic stroke is important to patients, family members, and physicians.

Objective: To develop and validate a model based on preprocedural and postprocedural characteristics to predict functional outcome for individual patients after EVT.

Design, Setting, And Participants: A prediction model was developed using individual patient data from 7 randomized clinical trials, performed between December 2010 and December 2014.

Purpose: To develop an automated deep learning system for detecting the presence and location of disc hemorrhages in optic disc photographs.

Design: Development and testing of a deep learning algorithm.

Methods: Optic disc photos (597 images with at least 1 disc hemorrhage and 1075 images without any disc hemorrhage from 1562 eyes) from 5 institutions were classified by expert graders based on the presence or absence of disc hemorrhage.

Background: Camostat inhibits severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in vitro. We studied the safety and efficacy of camostat in ACTIV-2/A5401, a phase 2/3 platform trial of therapeutics for COVID-19 in nonhospitalized adults.

Methods: We conducted a phase 2 study in adults with mild-to-moderate COVID-19 randomized to oral camostat for 7 days or a pooled placebo arm.

Increasing evidence indicates that circadian and diurnal rhythms robustly influence stroke onset, mechanism, progression, recovery, and response to therapy in human patients. Pioneering initial investigations yielded important insights but were often single-center series, used basic imaging approaches, and used conflicting definitions of key data elements, including what constitutes daytime versus nighttime. Contemporary methodologic advances in human neurovascular investigation have the potential to substantially increase understanding, including the use of large multicenter and national data registries, detailed clinical trial data sets, analysis guided by individual patient chronotype, and multimodal computed tomographic and magnetic resonance imaging.

BACKGROUND Neuroendocrine neoplasms are commonly seen in association with hormone production, and clinical signs that arise from these hormonal effects often manifest as the first presentation of malignancy. The excess production of parathyroid hormone (PTH) in particular, however, is primarily sporadic (80-85%) in clinical settings. In the context of malignancy, hyperparathyroidism manifestations arise most frequently from non-neuroendocrine pulmonary tumors through a ligand mimicker, parathyroid hormone-related peptide (PHrP).
