Cytokine expression of soft tissue cells cultured with titanium discs and their respective supernatants in vitro.

Objective: Titanium surface modifications improve osseointegration in dental and orthopedic implants. However, soft tissue cells can also reach the implant surface in immediate loading protocols. While previous research focused on osteogenic cells, the early response of soft tissue cells still needs to be better understood.

The Experience of Undocumented Individuals Denied Stem Cell Transplant for Hematologic Malignancies.

Background: Undocumented individuals with hematologic malignancies in the United States face barriers to receiving often-curative stem cell transplant (SCT), instead receiving inferior treatment with higher mortality. Federal and state policies' impact on undocumented individuals' lived experiences goes unnoticed.

Objective: To understand the experiences of this rare population of undocumented individuals with hematologic malignancies who cannot receive medically indicated SCT.

Global perspectives on transplant disparities.

Purpose Of Review: Our goal was to review and summarize the current state of global disease burden from organ failure and the efforts to improve outcomes with organ transplantation. We also reviewed intra- and inter-country disparities in organ failure and organ transplantation along with potential mechanisms to improve access to organ transplantation globally.

Recent Findings: Many disparities and inequities observed globally can be characterized by the country's income category.

Effects of irradiation-induced voids on confined layer slips in metallic nanolaminates.

Metallic nanolaminates are promising materials for nuclear applications due to their ability to withstand extreme radiation environments by trapping irradiation-induced defects. However, the effects of irradiation-induced voids on confined layer slips (CLS) in nanolaminates remain largely unexplored. In this study, molecular dynamics simulations are employed to investigate how void size and location impact CLS in two types of Ag/Cu nanolaminates.

Analyzing and predicting short-term substance use behaviors of persons who use drugs in the great plains of the U.S.

Background: Substance use induces large economic and societal costs in the U.S. Understanding the change in substance use behaviors of persons who use drugs (PWUDs) over time, therefore, is important in order to inform healthcare providers, policymakers, and other stakeholders toward more efficient allocation of limited resources to at-risk PWUDs.

Virtual Home Care for Patients With Acute Illness.

Design, Setting, And Participants: This retrospective cohort analysis, conducted from September 1, 2022, through August 31, 2023, included 2466 patients treated at a safety net hospital in Los Angeles County for 10 core illnesses and 24 other acute illnesses for which patients are commonly hospitalized.

Home Dialysis for Latinx Individuals Living with Kidney Failure: A Qualitative Study of Interdisciplinary Dialysis Clinicians.

Background: Latinx individuals experience 2 times the incidence of kidney failure compared to non-Latinx individuals and are less likely to utilize home dialysis therapies. In this qualitative study, interdisciplinary home dialysis clinicians were interviewed to understand the key factors and strategies used by clinicians to improve home dialysis uptake among the Latinx community.

Methods: One-to-one, semi-structured interviews were conducted between November 2021 and March 2023 with 25 home dialysis interdisciplinary clinicians in Denver, Colorado and Houston, Texas.

Supporting Financial Neutrality in Donation of Organs, Cells, and Tissues.

The avoidance of financial gain in the human body is an international ethical standard that underpins efforts to promote equity in donation and transplantation and to avoid the exploitation of vulnerable populations. The avoidance of financial loss due to donation of organs, tissues, and cells is also now recognized as an ethical imperative that fosters equity in donation and transplantation and supports the well-being of donors and their families. Nevertheless, there has been little progress in achieving financial neutrality in donations in most countries.

Toward Equity in Global Access to SoHO-based Therapies: Recommendations for Action.

Therapies derived from substances of human origin (SoHOs) such as organs, cells, and tissues provide life-saving or life-changing treatment for millions of people worldwide each year. However, many people lack timely access to SoHO-based therapies because of insufficient supplies of these exceptional health resources and/or broader barriers in access to healthcare. Despite well-established governmental commitments to promote health equity in general and equity of access to SoHOs in particular, information about inequities in access to most SoHO-based therapies is scarce.

Prevention of Trafficking in Organs, Tissues, and Cells.

Trafficking in human organs, cells, and tissues has long been a source of concern for health authorities and professionals, and several international ethical guidance documents and national laws have affirmed the prohibition of trade in these substances of human origin (SoHOs). However, despite considerable attention to the issue of organ trafficking, this remains a substantial and widespread problem internationally. In contrast, trafficking in cells, tissues, and medical products derived from SoHOs has received comparatively little attention, and the extent and nature of such trafficking remain largely unknown.

In-Center Hemodialysis Experiences Among Latinx Adults: A Qualitative Study.

Rationale & Objective: Latinx individuals are more likely to start and remain receiving in-center hemodialysis, over home dialysis, than non-Latinx White individuals. The objective of our study was to understand the drivers of sustained in-center dialysis and deterrents of switching to home dialysis use for Latinx individuals receiving in-center dialysis.

Study Design: This qualitative study used semistructured one-on-one interviews.

The Role of Language in Hospital Admissions: The COVID-19 Experience in a Safety-Net Hospital Emergency Department.

Background: Emergency departments (EDs) are often patients' first point of contact with the health care system. Race, ethnicity, and language all influence factors leading up to ED visits and patient experiences within the ED. There is limited evidence showing how race, ethnicity, and language interact to shape ED experiences, particularly during the COVID-19 pandemic when EDs were extremely strained.

What Should Clinicians in Organizations Without Established MLP Programs Do When Their Patients Need Lawyers to Meet Their Health Needs?

Undocumented people in the United States face innumerable legal and structural barriers to health and health care services, including for kidney failure. Their experiences vary across states and regions due to wide variation in insurance coverage and unreliable access to health-promoting resources, including medical-legal partnerships. This commentary on a case canvasses key policy about structural and legal determinants of health for undocumented persons.

How to Sample Dozens of Substitutions per Site with λ Dynamics.

Alchemical free energy methods are useful in computer-aided drug design and computational protein design because they provide rigorous statistical mechanics-based estimates of free energy differences from molecular dynamics simulations. λ dynamics is a free energy method with the ability to characterize combinatorial chemical spaces spanning thousands of related systems within a single simulation, which gives it a distinct advantage over other alchemical free energy methods that are mostly limited to pairwise comparisons. Recently developed methods have improved the scalability of λ dynamics to perturbations at many sites; however, the size of chemical space that can be explored at each individual site has previously been limited to fewer than ten substituents.

Continuous Glucose Monitor: Reclaiming Type 2 Diabetes Self-efficacy and Mitigating Disparities.

Context: The rise in continuous glucose monitor (CGM) use has been characterized by widening disparities between the least and most socially marginalized. Given access barriers, there is limited CGM patient experience information that is inclusive of those with type 2 diabetes mellitus from socially marginalized backgrounds.

Objective: To understand the CGM usage experience in the primary care setting across a US Medicaid population with type 2 diabetes at federally qualified health centers.

Centering marginalized voices in advocacy for equitable policy change in kidney disease.

Purpose Of Review: Inequities in kidney disease are a result of differences in healthcare access and inequitable structural policies that lead to downstream social challenges. An individual with kidney disease sits at the intersection of a variety of governmental and institutional policies that directly affect their access to kidney healthcare and different care delivery models. However, their voice in policy change is often neglected by stakeholders with more structural power.

Oxidative Stress is a shared characteristic of ME/CFS and Long COVID.

More than 65 million individuals worldwide are estimated to have Long COVID (LC), a complex multisystemic condition, wherein patients of all ages report fatigue, post-exertional malaise, and other symptoms resembling myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS). With no current treatments or reliable diagnostic markers, there is an urgent need to define the molecular underpinnings of these conditions. By studying bioenergetic characteristics of peripheral blood lymphocytes in over 16 healthy controls, 15 ME/CFS, and 15 LC, we find both ME/CFS and LC donors exhibit signs of elevated oxidative stress, relative to healthy controls, especially in the memory subset.

Exploring the Limits of the Generalized CHARMM and AMBER Force Fields through Predictions of Hydration Free Energy of Small Molecules.

Accurate force field parameters, potential energy functions, and receptor-ligand models are essential for modeling the solvation and binding of drug-like molecules to a receptor. A large and ever-growing chemical space of medicinally relevant scaffolds has also required these factors, especially force field parameters, to be highly transferable. Generalized force fields such as the CHARMM General Force Field (CGenFF) and the generalized AMBER force field (GAFF) have accomplished this feat along with other contemporaneous ones like OPLS.
