Article Synopsis
  • * Among patients on 1st or 2nd generation TKIs, those with a higher PLR (≥ 180) had a significantly shorter median progression-free survival (PFS) compared to those with a lower PLR (< 180).
  • * The findings suggest that while PLR is a useful predictor for traditional TKIs, it may be less relevant for the third generation TKI, osimertinib, which showed different impacts on blood cell counts and patient outcomes.

Calibrating workers' trust in intelligent automated systems.

Patterns (N Y)

September 2024

Chan Division of Occupational Science and Occupational Therapy, University of Southern California, Los Angeles, CA, USA.

With the exponential rise in the prevalence of automation, trust in such technology has become more critical than ever before. Trust is confidence in a particular entity, especially in regard to the consequences they can have for the trustor, and calibrated trust is the extent to which the judgments of trust are accurate. The focus of this paper is to reevaluate the general understanding of calibrating trust in automation, update this understanding, and apply it to worker's trust in automation in the workplace.

An integrated transcriptomic cell atlas of human neural organoids.

Nature

November 2024

Department of Biosystems Science and Engineering, ETH Zürich, Basel, Switzerland.

Human neural organoids, generated from pluripotent stem cells in vitro, are useful tools to study human brain development, evolution and disease. However, it is unclear which parts of the human brain are covered by existing protocols, and it has been difficult to quantitatively assess organoid variation and fidelity. Here we integrate 36 single-cell transcriptomic datasets spanning 26 protocols into one integrated human neural organoid cell atlas totalling more than 1.

Existing studies examining the predictive ability of biomarkers for cognitive outcomes do not account for variance due to measurement error, which could lead to under-estimates of the proportion of variance explained. We used data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) (N = 1084) to estimate the proportion of variance explained by Alzheimer's disease (AD) imaging biomarkers in four cognitive outcomes: memory, executive functioning, language, and visuospatial functioning. We compared estimates from standard models that do not account for measurement error, and multilevel models that do account for measurement error.

Article Synopsis
  • - The study evaluated trends and outcomes of gestational carrier (GC) pregnancies in the U.S. using data from over 14 million deliveries between 2017 and 2020, finding that the prevalence of GC pregnancies rose by 55% during this period.
  • - Among GCs, there was a higher likelihood of complications such as multiple pregnancies, placental abruption, and low-lying placenta, along with increased risks for late-preterm deliveries and postpartum hemorrhage in singleton births compared to non-GCs.
  • - While GC pregnancies are relatively rare, the findings indicate they are becoming more common and generally have favorable pre-pregnancy characteristics, but their obstetric outcomes can be mixed, especially regarding certain complications. *

Control of spatio-temporal patterning via cell growth in a multicellular synthetic gene circuit.

Nat Commun

November 2024

Eli and Edythe Broad CIRM Center for Regenerative Medicine and Stem Cell Research, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA.

A major goal in synthetic development is to build gene regulatory circuits that control patterning. In natural development, an interplay between mechanical and chemical communication shapes the dynamics of multicellular gene regulatory circuits. For synthetic circuits, how non-genetic properties of the growth environment impact circuit behavior remains poorly explored.

The Use of Event-Related Potentials in the Study of Schizophrenia: An Overview.

Adv Neurobiol

November 2024

Department of Psychiatry and Behavioral Sciences, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA.

Event-related potentials (ERPs) are small voltage changes in the brain that reliably occur in response to auditory or visual stimuli. ERPs have been extensively studied in both humans and animals to identify biomarkers, test pharmacological agents, and generate testable hypotheses about the physiological and genetic basis of schizophrenia. In this chapter, we discuss how ERPs are generated and recorded as well as review canonical ERP components in the context of schizophrenia research in humans.

Background: Despite higher dementia prevalence in racial and ethnic minoritized communities, they are underrepresented in Alzheimer's disease clinical trials. Community-based recruitment strategies are believed to yield positive outcomes in various fields, such as cancer and cardiovascular clinical trials, but their outcomes in Alzheimer's disease and Related Dementias (AD/ADRD) require further study. In this systematic rapid review, we synthesized the available evidence on community-engaged recruitment strategies in enhancing participation in AD/ADRD clinical trials and observational study participation.

A growing body of critical care research draws on real-world data from electronic health records (EHRs). The bedside clinician has myriad data sources to aid in clinical decision-making, but the lack of data sharing and harmonization standards leaves much of this data out of reach for multi-institution critical care research. The Society of Critical Care Medicine (SCCM) Discovery Data Science Campaign convened a panel of critical care and data science experts to explore and document unique advantages and opportunities for leveraging EHR data in critical care research.
