De-implementation of established practices is a common challenge in infection prevention and antimicrobial stewardship and a necessary part of the life cycle of healthcare quality improvement programs. Promoting de-implementation of ineffective antimicrobial use and increasingly of low-value diagnostic testing are cornerstones of stewardship practice. Principles of de-implementation science and the interplay of implementation and de-implementation are discussed in part I of this Society for Healthcare Epidemiology of America White Paper Series.

Background: Recent advances in high-throughput sequencing technologies have enabled the collection and sharing of a massive amount of omics data, along with its associated metadata-descriptive information that contextualizes the data, including phenotypic traits and experimental design. Enhancing metadata availability is critical to ensure data reusability and reproducibility and to facilitate novel biomedical discoveries through effective data reuse. Yet, incomplete metadata accompanying public omics data may hinder reproducibility and reusability and limit secondary analyses.

The defining property of eukaryotic cells is the storage of heritable genetic material in a nuclear compartment. For eukaryotic cells to carry out the myriad biochemical processes necessary for their function, macromolecules must be efficiently exchanged between the nucleus and cytoplasm. The nuclear pore complex (NPC) - which is a massive assembly of ~35 different proteins present in multiple copies totalling ~1,000 protein subunits and architecturally conserved across eukaryotes - establishes a size-selective channel for regulated bidirectional transport of folded macromolecules and macromolecular assemblies across the nuclear envelope.

Rotator cuff injuries are common and procedures of repair have evolved from open techniques to minimally invasive and arthroscopic ones. Despite these advances, the biomechanics, biology, and value of transosseous repairs remain superior, leading to the development of innovative devices that enable the utilization of this technique without the use of anchors, improving both the efficiency and safety of the procedure. This article reviews the latest advances in transosseous rotator cuff repair, highlighting its biomechanical advantages, as well as the factors that enhance recovery and offer more consistent long-term outcomes.

Red blood cell (RBC) size constrains the rate of diffusion of gases between (i) the environment and the capillary beds of the gas exchanger and (ii) the blood and organs. In birds, small RBCs with a high surface area to volume ratio permit a high O diffusion capacity and facilitate sustained, vigorous exercise. Unfortunately, our knowledge of archosaur cardiovascular evolution is incomplete without fossilized RBCs and blood vessels.

Getting caregivers to respond to their pain cries is vital for the human baby. Previous studies have shown that certain features of baby cries-the nonlinear phenomena (NLP)-enable caregivers to assess the pain felt by the baby. However, the extent to which these NLP mobilize the autonomic nervous system of an adult listener remains unexplored.

Microtubule-actin cross-linking factor 1 (MACF1) is a large protein of the spectraplakin family, which is essential for brain development. MACF1 interacts with microtubules through the growth arrest-specific 2 (Gas2)-related (GAR) domain. Heterozygous MACF1 missense variants affecting the zinc-binding residues in this domain result in a distinctive cortical and brain stem malformation.

Neurodevelopmental disorders often impair multiple cognitive domains. For instance, a genetic epilepsy syndrome might cause seizures due to cortical hyperexcitability and present with memory impairments arising from hippocampal dysfunction. This study examines how a single disorder differentially affects distinct brain regions using induced pluripotent stem cell (iPSC)-derived cortical- and hippocampal-ganglionic eminence assembloids to model developmental and epileptic encephalopathy 13, a condition arising from gain-of-function mutations in the SCN8A gene encoding the sodium channel Nav1.

Over the last decade, a range of research has demonstrated the detrimental impacts of policies criminalizing migration ("crimmigration") on Latinx mental health. In this study, we seek to examine youth perspectives on how crimmigration policies affect Latinx adolescents' connections to Latinx identity, culture, and communities and the implications for Latinx youth mental health. We explored how immigration enforcement policies affect Latinx youths' mental health using photovoice with ten youth in a high-deportation county in Atlanta in 2022.

Classical Hodgkin Lymphoma (CHL) is characterized by a complex tumor microenvironment (TME) that supports disease progression. While immune cell recruitment by Hodgkin and Reed-Sternberg (HRS) cells is well-documented, the role of non-malignant B cells in relapse remains unclear. Using single-cell RNA sequencing (scRNA-seq) on paired diagnostic and relapsed CHL samples, we identified distinct shifts in B-cell populations, particularly an enrichment of naïve B cells and a reduction of memory B cells in early-relapse compared to late-relapse and newly diagnosed CHL.
