Robust Bayesian graphical regression models for assessing tumor heterogeneity in proteomic networks.

Graphical models are powerful tools to investigate complex dependency structures in high-throughput datasets. However, most existing graphical models make one of two canonical assumptions: (i) a homogeneous graph with a common network for all subjects or (ii) an assumption of normality, especially in the context of Gaussian graphical models. Both assumptions are restrictive and can fail to hold in certain applications such as proteomic networks in cancer.

Proactive Approaches for a Wheelchair User in Pediatric Residency: A Case Study for Disability Inclusion.

Objective: Despite encountering many barriers to inclusion, people with disabilities are entering residency training in increasing numbers. However, the increase in representation among people with physical disabilities remains low, and published case studies and accommodations processes for wheelchair users in pediatric residency are absent in the literature. To support the inclusion of residents with physical disabilities in residency, we outline a proactive approach to the accommodations process and inclusion of a resident with a physical disability in pediatric residency.

The list-wide proportion congruency effect is larger when the distractor precedes the target: Evidence for conflict-independent control in the prime-probe task.

Stroop-like interference effects are smaller in blocks of mostly incongruent (MI) trials than in blocks of mostly congruent (MC) trials. It is unclear, though, how control processes trigger this list-wide proportion congruency effect (LWPCE). The attentional shift account posits that a memory of experiencing conflict more frequently in MI blocks than in MC blocks leads control processes to shift attention toward the target in MI blocks.

Modulations of response activation contribute to block-wide control: Evidence from proportion congruency effects in the prime-probe task.

Distractor-related congruency effects are smaller in blocks of mostly incongruent (vs. mostly congruent) trials. It remains unclear, though, how control processes produce this proportion congruency effect (PCE).

Assessment of the Behaviors of an In Vitro Brain Model On-Chip under Shockwave Impacts.

Herein we report the assessment of the effects of shockwave (SW) impacts on adult rat hippocampal progenitor cell (AHPC) neurospheres (NSs), which are used as in vitro brain models, for enhancing our understanding of the mechanisms of traumatic brain injury (TBI). The assessment has been achieved by using culture dishes and a new microchip. The microchip allows the chemicals released from the brain models cultured inside the cell culture chamber under SW impacts to diffuse to the nanosensors in adjacent sensor chambers through built-in diffusion barriers, which are used to prevent the cells from entering the sensor chambers, thereby mitigating the biofouling issues of the sensor surface.

Accelerated biological aging six decades after prenatal famine exposure.

To test the hypothesis that early-life adversity accelerates the pace of biological aging, we analyzed data from the Dutch Hunger Winter Families Study (DHWFS, N = 951). DHWFS is a natural-experiment birth-cohort study of survivors of in-utero exposure to famine conditions caused by the German occupation of the Western Netherlands in Winter 1944 to 1945, matched controls, and their siblings. We conducted DNA methylation analysis of blood samples collected when the survivors were aged 58 to quantify biological aging using the DunedinPACE, GrimAge, and PhenoAge epigenetic clocks.

Imaging in Lung Cancer Staging.

Lung cancer remains one of the leading causes of mortality worldwide, as well as in the United States. Clinical staging, primarily with imaging, is integral to stratify patients into groups that determine treatment options and predict survival. The eighth edition of the tumor, node, metastasis (TNM-8) staging system proposed in 2016 by the International Association for the Study of Lung Cancer remains the current standard for lung cancer staging.

Pericardial Recesses on Computed Tomography: Implications for the Pulmonologist.

The pericardium comprises a double-walled fibrous-serosal sac that encloses the heart. Reflections of the serosal layer form sinuses and recesses. With advances in multidetector computed tomography (CT) technology, pericardial recesses are frequently detected with thin-section CT.

Cell-Based Therapies for Rotator Cuff Injuries: An Updated Review of the Literature.

This review focuses on non-surgical treatment options for rotator cuff injuries and highlights the potential of mesenchymal stem cells (MSCs) as a potential regenerative approach. MSCs, sourced from various tissues like bone marrow and adipose tissue, exhibit promising mechanisms in vitro, influencing tendon-related gene expression and microenvironment modulation. Animal studies support this, showcasing MSCs' ability to reduce inflammation, improve tissue remodeling, and enhance repaired tendon strength.

Proactive response preparation contributes to contingency learning: novel evidence from force-sensitive keyboards.

Contingency learning can involve learning that the identity of one stimulus in a sequence predicts the identity of the next stimulus. It remains unclear, however, whether such learning speeds responses to the next stimulus only by reducing the threshold for triggering the expected response after stimulus onset or also by preparing the expected response before stimulus onset. To distinguish between these competing accounts, we manipulated the probabilities with which each of two prime arrows (Left and Right) were followed by each of two probe arrows (Up and Down) in a prime-probe task while using force-sensitive keyboards to monitor sub-threshold finger force.

Increased Care Provision and Caregiver Wellbeing: Moderation by Changes in Social Network Care Provision.

Objectives: Previous research links increased care provision to worse wellbeing among family and friend caregivers, both before and during the coronavirus disease 2019 (COVID-19) pandemic. We expand on this by incorporating data on caregivers' social networks and exploring the relationships between own and network changes in care during the pandemic and caregiver wellbeing.

Methods: We use nationally representative data from 1,876 family and friend caregivers in the first wave of our Care Network Connections over Time study (fielded 12/17/2020-1/4/2021) who had provided care continuously since before the COVID-19 pandemic began.

Illness uncertainty and quality of life in patients with advanced cancer and their family caregivers: An actor-partner interdependence model analysis.

Objective: The relationship between illness uncertainty and quality of life (QOL) has been examined for either the patient or caregiver, but not among the patient-caregiver dyads. This study examined relationships between illness uncertainty and QOL among patients with advanced cancer and family caregivers.

Methods: We conducted a secondary analysis of data from a randomized clinical trial that examined the effects of a dyadic-based intervention on psychological outcomes for patients with advanced cancer and family caregivers (N = 484 dyads).

PROBABILISTIC LEARNING OF TREATMENT TREES IN CANCER.

Accurate identification of synergistic treatment combinations and their underlying biological mechanisms is critical across many disease domains, especially cancer. In translational oncology research, preclinical systems such as patient-derived xenografts (PDX) have emerged as a unique study design evaluating multiple treatments administered to samples from the same human tumor implanted into genetically identical mice. In this paper, we propose a novel Bayesian probabilistic tree-based framework for PDX data to investigate the hierarchical relationships between treatments by inferring treatment cluster trees, referred to as treatment trees (R-tree).

Dyadic Peer Support to Improve Diet and Physical Activity Among African American Church Members: An Exploratory Study.

This study examined how African American church members communicated and cooperated as dyads to attain health goals. Participants completed nine weeks of group classes then worked as dyads for nine weeks. Communication logs and interviews were used to assess: (1) dyad communication and (2) dyad cooperation.

Perceived social support and COVID-19 impact on quality of life in college students: an observational study.

Background: The purposes of this study were to assess the current status of perceived social support and COVID-19 impact on quality of life, to investigate the association of perceived social support with the COVID-19 impact on quality of life, and to examine differences in perceived social support between better and worse COVID-19 impact on quality of life for the total sample and by gender.

Methods: Participants included 1296 university students (399 male, 871 female, 22 transgender, non-binary, or other) with a mean age of 21.5 (SD  =  2.

Expanding ACTA2 genotypes with corresponding phenotypes overlapping with smooth muscle dysfunction syndrome.

Pathogenic variants in ACTA2, encoding smooth muscle α-actin, predispose to thoracic aortic aneurysms and dissections. ACTA2 variants altering arginine 179 predispose to a more severe, multisystemic disease termed smooth muscle dysfunction syndrome (SMDS; OMIM 613834). Vascular complications of SMDS include patent ductus arteriosus (PDA) or aortopulmonary window, early-onset thoracic aortic disease (TAD), moyamoya-like cerebrovascular disease, and primary pulmonary hypertension.

The American Venous Forum, American Vein and Lymphatic Society and the Society for Vascular Medicine expert opinion consensus on lymphedema diagnosis and treatment.

Background: Lymphedema imposes a significant economic and social burden in modern societies. Controversies about its risk factors, diagnosis, and treatment permeate the literature. The goal of this study was to assess experts' opinions on the available literature on lymphedema while following the Delphi methodology.

The impact of diarrhoea measurement methods for under 5s in low- and middle-income countries on estimated diarrhoea rates at the population level: A systematic review and meta-analysis of methodological and primary empirical studies.

Objective: We systematically reviewed all studies published between 2000 and June 2021 that estimated under 5 diarrhoea rates in low- and middle-income countries and extracted data on diarrhoea rates, measurement methods and reactivity.

Methods: We summarised data from studies that performed direct comparisons of methods, and indirectly compared studies which utilised only one method using meta-regression to determine the association between methods and estimated diarrhoea rates.

Results: In total, 288 studies met our inclusion criteria: 4 direct comparisons and 284 studies utilising only one measurement method.

A comparison of traditional diarrhoea measurement methods with microbiological and biochemical indicators: A cross-sectional observational study in the Cox's Bazar displaced persons camp.

Background: Water, Sanitation, and Hygiene (WASH) systems aim to reduce the spread of enteric pathogens, particularly amongst children under five years old. The most common primary outcome of WASH trials is carer-reported diarrhoea. We evaluate different diarrhoea survey instruments as proxy markers of enteric pathogen presence in stool.

Supramolecular arrangement of protein in nanoparticle structures predicts nanoparticle tropism for neutrophils in acute lung inflammation.

This study shows that the supramolecular arrangement of proteins in nanoparticle structures predicts nanoparticle accumulation in neutrophils in acute lung inflammation (ALI). We observed homing to inflamed lungs for a variety of nanoparticles with agglutinated protein (NAPs), defined by arrangement of protein in or on the nanoparticles via hydrophobic interactions, crosslinking and electrostatic interactions. Nanoparticles with symmetric protein arrangement (for example, viral capsids) had no selectivity for inflamed lungs.

Actigraphic and Self-reported Sleep Measures in Older Adults: Factor Analytic Study.

Actigraphy has been used to measure older adults' sleep, but few studies have evaluated the factor structure among actigraphy-measured sleep parameters. Additionally, previous studies have reported the association between actigraphy-measured and self-reported sleep parameters in older adults but have not controlled for covariates of gender, insomnia, cognitive impairment, depression, and health conditions. We therefore investigated the factor structure of actigraphy-measured sleep parameters and, controlling for covariates, the association between actigraphy-measured and self-reported sleep parameters in 62 older adults (female: 75.
