Background: Breast cancer patients are at risk of acute decompensated heart failure (ADHF) and protein-energy malnutrition (PEM) due to chemoradiation effects or cancer itself. There are no existing studies on the impact of PEM on breast cancer patients hospitalized for ADHF. This study aims to evaluate the effects of PEM on breast cancer patients admitted for ADHF.

Methods: We used a discrete event simulation to estimate life expectancy and HLE among a cohort of Black adults from the Jackson Heart Study (n=4933) from age 20 to 100 years or until death. We modeled preventing hypertension as having BP <130/80 mm Hg and maintaining normal BP as having BP <120/80 mm Hg across the lifespan.
Objective: This scoping review aimed to map the volume (number of studies) and nature (topics and designs) of chiropractic education research and scholarly publications on chiropractic learners and programs worldwide.
Introduction: Despite the expansion of the chiropractic profession and its recognition by entities such as the World Health Organization, a gap exists in comprehending the international landscape of chiropractic education. No prior studies have systematically mapped the volume and nature of chiropractic education research and scholarly publications.
Alterations of the extracellular matrix (ECM), including both mechanical (such as stiffening of the ECM) and chemical (such as variation of adhesion proteins and deposition of hyaluronic acid (HA)) changes, in malignant tissues have been shown to mediate tumor progression. To survey how cells from different tissue types respond to various changes in ECM mechanics and composition, we measured physical characteristics (adherent area, shape, cell stiffness, and cell speed) of 25 cancer and 5 non-tumorigenic cell lines on 7 different substrate conditions. Our results indicate substantial heterogeneity in how cell mechanics changes within and across tissue types in response to mechanosensitive and chemosensitive changes in ECM.

Methods: This was an electronic health record-based retrospective cohort study of patients with high office BP (≥140/90 mmHg) referred for ABPM at a medical center in New York City between 2016 and 2020.
The diagnosis and management of hypertension have been based primarily on blood pressure (BP) measurement in the office setting. Higher out-of-office BP is associated with increased risk of cardiovascular disease, independent of office BP. Home BP monitoring (HBPM) consists of the measurement of BP by a person outside of the office at home and is a validated approach for out-of-office BP measurement.

Although the nucleus is generally seen as the stiffest organelle in the cell, cells can nevertheless deform the nucleus to large strains by small mechanical stresses. Here, we show that the mechanical response of the cell nucleus exhibits active fluidization that is driven by the BRG1 motor of the SWI/SNF/BAF chromatin remodeling complex.

Here we show that the cytoskeletal protein vimentin plays an important role in increasing cell-generated forces transmitted to the cell nucleus, resulting in increased nuclear deformations in strongly polarized cells. Using micropatterned substrates to geometrically control cell shape in wild-type and vimentin-null cells, we show vimentin increases polarization and deformation of the cell nucleus.

The present study aimed to establish a current prevalence of SP and associated determinants in Wales by retrospectively analyzing data from the National Survey for Wales Dataset (NSWD). The NSWD is a large-scale cross-sectional, representative sample of adults across Wales, UK.

Recent studies indicate that the chromatin within the nucleus cannot be treated as a homogeneous material. To elucidate its material properties, we combine optical tweezers manipulation of isolated nuclei with multi-color fluorescence imaging of lamin and chromatin to map the response of nuclei to local deformations.

The ability of MuSCs to regenerate damaged tissues declines markedly with aging and in diseases such as Duchenne muscular dystrophy, but the underlying causes of MuSC dysfunction remain poorly understood. Both aging and disease result in dramatic increases in the stiffness of the muscle tissue microenvironment from fibrosis.

Although the nucleus is generally seen as the stiffest organelle in the cell, cells can nevertheless deform the nucleus to large strains by small mechanical stresses.

A retrospective analysis of the Longitudinal Study of Ageing Danish Twins was performed to determine any potential relationships between BP/NP and cognitive function adjusting for age, sex, educational and socioeconomic status. A total of 4731 adults (2788 females/1943 males) aged 78 ± 6 (SD) years were included in the analysis.

The primary objective of this study was to determine whether VR changed the revised Edmonton Symptom and Assessment System (ESAS-r) score representing an effective improvement in symptom control and well-being.
Methods And Analysis: This study reports on 60 participants recruited from hospital inpatient oncology and palliative care lists, to participate in an unblinded, VR intervention.
Objective: This study aimed to (1) collect and analyze statements about how to celebrate chiropractic in the present and roles that chiropractors may fulfill in the future, (2) identify if there was congruence among the themes between present and future statements, and (3) offer a model about the chiropractic profession that captures its complex relationships that encompass its interactions within microsystem, mesosystem, exosystem, and macrosystem levels.
Methods: For this qualitative analysis, we used pattern and grounded theory approaches. A purposive sample of thought leaders in the chiropractic profession were invited to answer the following 2 open-ended questions: (1) envision the chiropractor of the future, and (2) recommendations on how to celebrate chiropractic.
Perinatal quality improvement is a method to increase obstetric safety and promote health equity.

This article describes an approach to recruit AA families into an AD genomic study and characteristics of seeds (family connectors) used to overcome recruitment barriers of AA families into AD research.
Methods: A four-step outreach and snowball sampling approach relying on family connectors was used to recruit AA families.
Aim: The study aimed to measure and describe the mental health impact of COVID-19 on Australian pre-registration nursing students.
Background: The COVID -19 pandemic has had a swift and significant impact on nursing students across the globe. The pandemic was the catalyst for the closure of schools and universities across many countries.
Importance: In 2020, some health insurance plans updated their medical policy to cover germline genetic testing for all patients diagnosed with colorectal cancer (CRC). Guidelines for universal tumor screening via microsatellite instability and/or immunohistochemistry (MSI/IHC) for mismatch repair protein expression for patients with CRC have been in place since 2009.
Objectives: To examine whether uptake of MSI/IHC screening and germline genetic testing in patients with CRC has improved under these policies and to identify actionable findings and management implications for patients referred for germline genetic testing.
In this work, we investigate whether stiffening in compression is a feature of single cells and whether the intracellular polymer networks that comprise the cytoskeleton (all of which stiffen with increasing shear strain) stiffen or soften when subjected to compressive strains. We find that individual cells, such as fibroblasts, stiffen at physiologically relevant compressive strains, but genetic ablation of vimentin diminishes this effect. Further, we show that unlike networks of purified F-actin or microtubules, which soften in compression, vimentin intermediate filament networks stiffen in both compression and extension, and we present a theoretical model to explain this response based on the flexibility of vimentin filaments and their surface charge, which resists volume changes of the network under compression.
