Is Femoral Head to Acetabular Cup Ratio Associated With Dislocation After Total Hip Arthroplasty?

Background: Dislocation remains a common complication following total hip arthroplasty (THA). Previous literature has shown that the femoral head-to-neck ratio is essential in hip motion, function, and stability. While large femoral heads and dual mobility bearings have been developed to improve stability, it remains unknown if the ratio between femoral head size to acetabular cup size also plays a role in stability.

Coupling of single nanodiamonds hosting SiV color centers to plasmonic double bowtie microantennas.

Color centers are promising single-photon emitters owing to their operation at room temperature and high photostability. In particular, using nanodiamonds as a host material is of interest for sensing and metrology. Furthermore, being a solid-state system allows for incorporation to photonic systems to tune both the emission intensity and photoluminescence spectrum and therefore adapt the individual color center to desired properties.

Protocol to study neuronal membrane proteasome function in mouse peripheral sensory neurons.

Neuronal membrane proteasomes (NMPs) are expressed on a subset of somatosensory dorsal root ganglion (DRG) neurons and influence mechanical and pain sensitivity. Here, we present a protocol for studying NMP function in mouse peripheral sensory neurons. We describe steps for procuring and culturing primary DRG neurons.

Integrin-activating protein Invasin sustains long-term expansion of primary epithelial cells as 2D organoid sheets.

Matrigel/BME, a basement membrane-like preparation, supports long-term growth of epithelial 3D organoids from adult stem cells [T. Sato , , 262-265 (2009); T. Sato , , 1762-1772 (2011)].

Mesenchymal Stem/Stromal Cells Reverse Adipose Tissue Inflammation in Pigs with Metabolic Syndrome and Renovascular Hypertension.

Metabolic syndrome (MetS) is associated with low-grade inflammation, which can be exacerbated by renal artery stenosis (RAS) and renovascular hypertension, potentially worsening outcomes through pro-inflammatory cytokines. This study investigated whether mesenchymal stem/stromal cells (MSCs) could reduce fat inflammation in pigs with MetS and RAS. Twenty-four pigs were divided into Lean (control), MetS, MetS + RAS, and MetS + RAS + MSCs.

Improving Access to Community-Based Services for Sexual Assault Survivors.

Background: Emergency department (ED) encounters are often the only healthcare provider encounter for patients seeking care after a reported sexual assault (SA), making the encounter a crucial opportunity to connect patients to support services in the community. An opportunity existed at an urban Level II trauma center to standardize SA discharge planning.

Aims: This quality improvement project aimed to improve access to SA support services.

Evaluating Harms Associated with Prolonged Antibiotic Duration of Therapy in Community Dwelling Older Adults: A Cohort Study using Instrumental Variable Analysis.

Background: Shorter courses of antibiotic therapy are increasingly recommended to reduce antibiotic exposure. However quantifying the real-world impact of duration of therapy is hindered by bias common in observational studies. We aimed to evaluate the harms and benefits of longer versus shorter duration of therapy in older adults.

Early adversity and inflammation at midlife: the moderating role of internalizing psychopathology.

Background: Childhood adversity has been associated with increased peripheral inflammation in adulthood. However, not all individuals who experience early adversity develop these inflammatory outcomes. Separately, there is also a link between various internalizing emotional distress conditions (e.

A novel prognostic risk model for patients with refractory/relapsed acute myeloid leukemia receiving venetoclax plus hypomethylating agents.

Off-label hypomethylating agents and venetoclax (HMA/VEN) are often used for relapsed and refractory (R/R) AML patients. However, predictors of outcome are elusive. The objective of the current retrospective observational multicenter study of 240 adult patients (median age 68.

Correlates of Perceived Illness Severity and Terminality in Advanced Lung and Prostate Cancer.

Context: While prognostic awareness has been commonly assessed as perceived illness terminality in patients with advanced cancer, both perceptions of illness severity and terminality may be correlated with symptom burden and quality of life.

Objectives: The present study examined physical and psychological symptoms, quality of life, and smoking status in relation to perceived illness severity and terminality in patients with advanced, inoperable lung and prostate cancer.

Methods: Patients (N=198) were recruited from hospitals in the midwestern U.

Genomic Landscape of Chromosome X Factor VIII: From Hemophilia A in Males to Risk Variants in Females.

Background: Variants within factor VIII (F8) are associated with sex-linked hemophilia A and thrombosis, with gene therapy approaches being available for pathogenic variants. Many variants within F8 remain variants of uncertain significance (VUS) or are under-explored as to their connections to phenotypic outcomes.

Methods: We assessed data on F8 expression while screening the UniProt, ClinVar, Geno2MP, and gnomAD databases for F8 missense variants; these collectively represent the sequencing of more than a million individuals.

Injury-induced Neuregulin-ErbB signaling from muscle mobilizes stem cells for whole-body regeneration in Acoels.

The activation of progenitor cells near wound sites is a common feature of regeneration across species, but the conserved signaling mechanisms responsible for this step in whole-body regeneration are still incompletely understood. The acoel undergoes whole-body regeneration using Piwi+ pluripotent adult stem cells (neoblasts) that accumulate at amputation sites early in the regeneration process. The EGFR signaling pathway has broad roles in controlling proliferation, migration, differentiation, and cell survival across metazoans.

High-resolution mapping of cell cycle dynamics during steady-state T cell development and regeneration in vivo.

Control of cell proliferation is critical for the lymphocyte life cycle. However, little is known about how stage-specific alterations in cell cycle behavior drive proliferation dynamics during T cell development. Here, we employed in vivo dual-nucleoside pulse labeling combined with the determination of DNA replication over time as well as fluorescent ubiquitination-based cell cycle indicator mice to establish a quantitative high-resolution map of cell cycle kinetics of thymocytes.

Deep learning-based aberration compensation improves contrast and resolution in fluorescence microscopy.

Optical aberrations hinder fluorescence microscopy of thick samples, reducing image signal, contrast, and resolution. Here we introduce a deep learning-based strategy for aberration compensation, improving image quality without slowing image acquisition, applying additional dose, or introducing more optics. Our method (i) introduces synthetic aberrations to images acquired on the shallow side of image stacks, making them resemble those acquired deeper into the volume and (ii) trains neural networks to reverse the effect of these aberrations.

CD63 as novel target for nanoemulsion-based F MRI imaging and drug delivery to activated cardiac fibroblasts.

Cardiac fibroblasts are activated following myocardial infarction (MI) and cardiac fibrosis is a major driver of the growing burden of heart failure. A non-invasive targeting method for activated cardiac fibroblasts would be advantageous because of their importance for imaging and therapy. Targeting was achieved by linking a 7-amino acid peptide (EP9) to a perfluorocarbon-containing nanoemulsion (PFC-NE) for visualization by F-combined with H-MRI.

Uncertainty reduction as an alternative explanation of historical myths.

We agree with Sijilmassi et al. that historical myths are a tool for coalition recruitment. We argue, however, that a close fit between an evolved entity and an identified function does not imply that the latter is the critical evolutionary trigger.

Preventative treatment of tuberous sclerosis complex with sirolimus: Phase I safety and efficacy results.

Objective: Tuberous sclerosis complex (TSC) results from overactivity of the mechanistic target of rapamycin (mTOR). Sirolimus and everolimus are mTOR inhibitors that treat most facets of TSC but are understudied in infants. We sought to understand the safety and potential efficacy of preventative sirolimus in infants with TSC.

A minority of Th1 and Tfh effector cells express survival genes shared by memory cell progeny that require IL-7 or TCR signaling to persist.

It is not clear how CD4 memory T cells are formed from a much larger pool of earlier effector cells. We found that transient systemic bacterial infection rapidly generates several antigen-specific T helper (Th)1 and T follicular helper (Tfh) cell populations with different tissue residence behaviors. Although most cells of all varieties had transcriptomes indicative of cell stress and death at the peak of the response, some had already acquired a memory cell signature characterized by expression of genes involved in cell survival.

Early Engraftment and Immune Kinetics Following Allogeneic Transplant Using a Novel Reduced-Toxicity Transplant Strategy in Children/Adolescents with High-Risk Transfusion-Dependent Thalassemia: Early Results of the ThalFAbS Trial.

Allogeneic hematopoietic stem cell transplantation is challenging for patients with transfusion-dependent thalassemia who have experienced iron overload and received chronic transfusion support. A transplantation strategy including a reduced-intensity preparative regimen and tailored immunosuppression to support donor engraftment and prevent graft-versus-host disease (GVHD) was developed for this population. The combination of a pretransplantation immunosuppression phase with reduced dosing of fludarabine/prednisone, a treosulfan-based preparative regimen with reduced cyclophosphamide dosing, and introduction of a calcineurin/methotrexate-free GVHD prophylaxis/engraftment supporting regimen with abatacept/sirolimus/antithymocyte globulin was tested.

Tumor necrosis factor-stimulated gene-6 inhibits endoplasmic reticulum stress in the ischemic mouse kidney.

Kidney tissue injury in renal artery stenosis (RAS) involves inflammation, endoplasmic reticulum stress (ERS), and mitochondria damage. Tumor necrosis factor-stimulated gene-6 (TSG-6), an endogenous reparative molecule, may decrease ERS and improve renal function. To assess its impact on the stenotic murine kidney, we injected TSG-6 or vehicle for two weeks in mice with RAS.
