Association Between Delayed/Forgone Medical Care and Resource Utilization Among Women with Breast Cancer in the United States.

Background: Although high treatment costs of breast cancer care are well documented, the relationship between delayed/forgone (D/F) care and resource utilization among patients with breast cancer is unknown. This study sought to investigate the relationship between D/F care, resource use, and healthcare expenditures among patients with breast cancer.

Methods: Data on adult female patients with breast cancer were obtained from the Medical Expenditure Panel Survey to assess resource utilization and expenditures in the United States from 2007 to 2017.

Bilingualism, sleep, and cognition: An integrative view and open research questions.

Sleep and language are fundamental to human existence and have both been shown to substantially affect cognitive functioning including memory, attentional performance, and cognitive control. Surprisingly, there is little-to-no research that examines the shared impact of bilingualism and sleep on cognitive functions. In this paper, we provide a general overview of existing research on the interplay between bilingualism and sleep with a specific focus on executive functioning.

Quantitative single-molecule analysis of assembly and Ca-dependent disassembly of synaptotagmin oligomers on lipid bilayers.

Synaptotagmin-1 (Syt-1) self-assembles into ring-like oligomers, and genetic and biochemical evidence suggest that oligomerization is needed to clamp synaptic vesicles and stabilize them for Ca-evoked release. However, oligomerization has not yet been demonstrated on lipid bilayers or studied in quantitative biophysical terms. Here we utilize single-molecule imaging methods to monitor the assembly and disassembly of oligomeric clusters of Syt-1 on lipid bilayers in real-time.

A proteome-wide quantitative platform for nanoscale spatially resolved extraction of membrane proteins into native nanodiscs.

The native membrane environment profoundly influences every aspect of membrane protein (MP) biology. Despite this, the most prevalent method of studying MPs uses detergents to disrupt and remove this vital membrane context, impeding our ability to decipher the local molecular context and its effect. Here we develop a membrane proteome-wide platform that enables rapid spatially resolved extraction of target MPs directly from cellular membranes into native nanodiscs that maintain the local membrane context, using a library of membrane-active polymers.

Multicenter comparative study of polysomnography outcomes in children with the monogenic disorder sickle cell disease.

Study Objectives: Sleep-disordered breathing (SDB) is prevalent in children with sickle cell disease (SCD) and is associated with worse outcomes. This study aims to compare the outcomes of polysomnography (PSG) performed for pediatric patients with SCD at three United States centers.

Methods: We included children with SCD aged 0-21 who underwent PSG at three American Academy of Sleep Medicine accredited centers: the University of Alabama at Birmingham (UAB), the University of Florida (UF), and Duke University Hospital (DUH), between 2012 and 2022.

Modeling individual differences in vocabulary development: A large-scale study on Japanese heritage speakers.

This study examines when the vocabulary knowledge of Japanese heritage speakers (HSs; N = 427, M = 9.96, female = 213) begins to diverge from monolingual counterparts (N = 136, M = 6.69, female = 65) and what factors explain individual differences in HS development.

Case Report: Aplastic anemia related to a novel variant.

A 20-year-old male patient with a history of celiac disease came to medical attention after developing profound fatigue and pancytopenia. Evaluation demonstrated pan-hypogammaglobulinemia. There was no history of significant clinical infections.

Brain correlates of attentional load processing reflect degree of bilingual engagement: Evidence from EEG.

The present study uses electroencephalography (EEG) with an N-back task (0-, 1-, and 2-back) to investigate if and how individual bilingual experiences modulate brain activity and cognitive processes. The N-back is an especially appropriate task given recent proposals situating bilingual effects on neurocognition within the broader attentional control system (Bialystok and Craik, 2022). Beyond its working memory component, the N-Back task builds in complexity incrementally, progressively taxing the attentional system.

Long-Term Prospective Outcomes of Intensity Modulated Radiotherapy for Locally Advanced Lung Cancer: A Secondary Analysis of a Randomized Clinical Trial.

Importance: The optimal radiotherapy technique for unresectable locally advanced non-small cell lung cancer (NSCLC) is controversial, so evaluating long-term prospective outcomes of intensity-modulated radiotherapy (IMRT) is important.

Objective: To compare long-term prospective outcomes of patients receiving IMRT and 3-dimensional conformal radiotherapy (3D-CRT) with concurrent carboplatin/paclitaxel for locally advanced NSCLC.

Design, Setting, And Participants: A secondary analysis of a prospective phase 3 randomized clinical trial NRG Oncology-RTOG 0617 assessed 483 patients receiving chemoradiotherapy (3D-CRT vs IMRT) for locally advanced NSCLC based on stratification.

Utilizing Large Language Models to Generate Synthetic Data to Increase the Performance of BERT-Based Neural Networks.

An important problem impacting healthcare is the lack of available experts. Machine learning (ML) models may help resolve this by aiding in screening and diagnosing patients. However, creating large, representative datasets to train models is expensive.

Crowdsourcing with Enhanced Data Quality Assurance: An Efficient Approach to Mitigate Resource Scarcity Challenges in Training Large Language Models for Healthcare.

Large Language Models (LLMs) have demonstrated immense potential in artificial intelligence across various domains, including healthcare. However, their efficacy is hindered by the need for high-quality labeled data, which is often expensive and time-consuming to create, particularly in low-resource domains like healthcare. To address these challenges, we propose a crowdsourcing (CS) framework enriched with quality control measures at the pre-, real-time-, and post-data gathering stages.

Degree of multilingual engagement modulates resting state oscillatory activity across the lifespan.

Multilingualism has been demonstrated to lead to a more favorable trajectory of neurocognitive aging, yet our understanding of its effect on neurocognition across the lifespan remains limited. We collected resting state EEG recordings from a sample of multilingual individuals across a wide age range. Additionally, we obtained data on participant multilingual language use patterns alongside other known lifestyle enrichment factors.

Selective deforestation and exposure of African wildlife to bat-borne viruses.

Proposed mechanisms of zoonotic virus spillover often posit that wildlife transmission and amplification precede human outbreaks. Between 2006 and 2012, the palm Raphia farinifera, a rich source of dietary minerals for wildlife, was nearly extirpated from Budongo Forest, Uganda. Since then, chimpanzees, black-and-white colobus, and red duiker were observed feeding on bat guano, a behavior not previously observed.

"Should I Prioritize My Cancer or My Diabetes?": Patient-Perceived Barriers to Co-Managing Cancer and Diabetes Mellitus.

Among patients with cancer, diabetes mellitus (DM) is a prevalent comorbid condition. With an aging population and an increase in the prevalence of cancer and DM, the number of cancer patients with DM will rise. To date, studies have largely focused on understanding the context of cancer and DM co-management from the perspectives of oncology and primary care providers.

Sex-specific associations between AD genotype and the microbiome of human amyloid beta knock-in (hAβ-KI) mice.

Introduction: Emerging evidence links changes in the gut microbiome to late-onset Alzheimer's disease (LOAD), necessitating examination of AD mouse models with consideration of the microbiome.

Methods: We used shotgun metagenomics and untargeted metabolomics to study the human amyloid beta knock-in (hAβ-KI) murine model for LOAD compared to both wild-type (WT) mice and a model for early-onset AD (3xTg-AD).

Results: Eighteen-month female (but not male) hAβ-KI microbiomes were distinct from WT microbiomes, with AD genotype accounting for 18% of the variance by permutational multivariate analysis of variance (PERMANOVA).

Unraveling cellular complexity with transient adapters in highly multiplexed super-resolution imaging.

Mapping the intricate spatial relationships between the many different molecules inside a cell is essential to understanding cellular functions in all their complexity. Super-resolution fluorescence microscopy offers the required spatial resolution but struggles to reveal more than four different targets simultaneously. Exchanging labels in subsequent imaging rounds for multiplexed imaging extends this number but is limited by its low throughput.

Being a heritage speaker matters: the role of markedness in subject-verb person agreement in Italian.

This study examines online processing and offline judgments of subject-verb person agreement with a focus on how this is impacted by markedness in heritage speakers (HSs) of Italian. To this end, 54 adult HSs living in Germany and 40 homeland Italian speakers completed a self-paced reading task (SPRT) and a grammaticality judgment task (GJT). Markedness was manipulated by probing agreement with both first-person (marked) and third-person (unmarked) subjects.
