Background Distinguishing lumbar pain generators from incidental findings at MRI can be difficult. Dictated reports may become lists of findings that cannot be ranked in order of diagnostic importance. Purpose To determine whether patient-reported symptom information can improve the interpretation of lumbar spine MRI by using the spine specialist as the reference standard.

Background: Shortages of nurses are one of the biggest challenges healthcare systems face around the world. Given the wide range of contexts and individuals working in nursing, a 'one-size-fits-all' retention strategy is unlikely to be effective. Knowing what matters most to nurses at different career stages would help employers and policy-makers who want to enhance nurse retention to design tailored strategies.

Article Synopsis
  • The "innate-like" T cell compartment, referred to as T, consists of diverse T cells that bridge innate and adaptive immunity and is analyzed using advanced techniques like single-cell RNA sequencing.
  • In human blood, most T cells exhibit an effector program driven by unique transcription factors, contrasting with conventional T cells, while varied developmental stages are observed in thymic T cells.
  • Unlike mice, human T cells do not form multiple effector subsets but show a mix of type 1 and type 17 effector potential, revealing key differences in immune regulation between species.

The mechanisms of psychotic symptoms such as hallucinations and delusions are often investigated in fully formed illness, well after symptoms emerge. These investigations have yielded key insights but are not well positioned to reveal the dynamic forces underlying symptom formation itself. Understanding symptom development over time would allow us to identify steps in the pathophysiological process leading to psychosis, shifting the focus of psychiatric intervention from symptom alleviation to prevention.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is defined by the presence of positive cardiac biomarkers with clinical evidence of infarction, the absence of significant coronary stenosis (≥50%) on angiography, and the lack of alternative diagnosis for the index presentation. MINOCA poses a diagnostic and therapeutic challenge due to the various pathophysiologic mechanisms underlying its presentation. Coronary artery plaque disruption is recognized as a crucial mechanism contributing to MINOCA.

The "innate-like" T cell compartment, known as T, represents a diverse group of T cells that straddle the boundary between innate and adaptive immunity, having the ability to mount rapid responses following activation. In mice, this ability is acquired during thymic development. We explored the transcriptional landscape of T compared to conventional T cells (T) in the human thymus and blood using single cell RNA sequencing and flow cytometry.

Objectives: To evaluate existing literature to understand the utility and safety of uvulopalatopharyngoplasty (UPPP) for treatment of pediatric obstructive sleep apnea (OSA).

Methods: A literature review was conducted by two authors to search for studies from the inception of two databases until March 1, 2023. Studies in which participants were under 18 years of age and underwent UPPP for OSA or upper airway obstruction were selected.

Article Synopsis
  • The study explores how variations in HLA and KIR genes influence immune responses and COVID-19 severity, analyzing data from 403 non-hospitalized and 1575 hospitalized patients in Italy.
  • A specific KIR gene variant (KIR2DS4*001) is linked to an increased risk of severe COVID-19, particularly in individuals who have two copies of this variant, while the HLA variant HLA-DPB1*13:01 appears to offer protective effects against severe disease.
  • The research finds a connection between autoantibodies against interferon-alpha and COVID-19 severity, with certain genetic markers influencing the presence of these antibodies, indicating that genetic polymorphism plays a critical role

Background: In 2010, the Office of the US Army Surgeon General recommended the Veterans Administration (VA) assess pain using the Defense and Veterans Pain Rating Scale (DVPRS). One item in the DVPRS is for measuring pain intensity. This item contains a combination of five response metrics: categories, faces, colors, numbers, and functional descriptors.

Purpose: Hereditary hemochromatosis (HH) may cause iron deposition in cardiac tissue. We aimed to describe the echocardiographic findings in patients with HH and identify risk factors for cardiac dysfunction.

Methods: In this retrospective study, we included patients with HH who underwent transthoracic echocardiography at our tertiary care center between August 2000 and July 2022.

Background: Few programs assess for outcomes once translated into practice. The Physical Activity for Lifelong Success program was developed as a center-based public health intervention and shown to improve walking speed and distance among older adults with type 2 diabetes. We adapted the program for community-based delivery by lay leaders to physically inactive older adults.

Breeding perennial tree crops often requires prediction of mature performance from juvenile data. To assess the utility of juvenile screens to predict salinity tolerance of mature pistachio trees, we compared performance of 3-month ungrafted seedlings and 4-year-old grafted rootstocks under salinity stress. The QTL allele associated with higher salt exclusion from seedling leaves conferred lower growth in saline field conditions, suggesting that mapping QTL in seedlings may be easier than discerning the optimal allele for field performance.

We assessed challenges that the COVID-19 pandemic presented for mental health systems and the responses to these challenges in 14 countries in Europe and North America. Experts from each country filled out a structured questionnaire with closed- and open-ended questions between January and June 2021. We conducted thematic analysis to investigate the qualitative responses to open-ended questions, and we summarized the responses to closed-ended survey items on changes in telemental health policies and regulations.

Objectives: To evaluate posterior glenohumeral capsule edema compared to other MRI findings in adhesive capsulitis (AC).

Methods: This study was approved by the local Institutional Review Board and it is HIPAA compliant. A retrospective search identified subjects who received fluoroscopically guided intra-articular corticosteroid injections for AC and had an MRI within 6 months prior to injection.

Most human killer cell immunoglobulin-like receptors (KIR) are expressed by natural killer (NK) cells and recognize HLA class I molecules as ligands. KIR3DL3 is a conserved but polymorphic inhibitory KIR recognizing a B7 family ligand, HHLA2, and is implicated for immune checkpoint targeting. The expression profile and biological function of KIR3DL3 have been somewhat elusive, so we searched extensively for KIR3DL3 transcripts, revealing highly enriched expression in γδ and CD8 T cells rather than NK cells.

 Expanding access to care has been shown to impact patient care and disease epidemiology for different disease states, but has not been studied in pituitary adenoma. We hypothesize that increasing access to care-which includes diagnostics-through the Affordable Care Act (ACA) and Medicaid expansion has increased identification of pituitary adenomas.  The National Cancer Institute's Surveillance, Epidemiology, and End Results database was utilized to identify patients with pituitary adenomas from 2007-to 2016 yielding 39,120 cases.

This study aims to evaluate if race and ethnicity affect rates of tympanostomy tube (TT) placement during inpatient pediatric admissions in children with otologic conditions. A review of the 2016 Kids' Inpatient Database was conducted based on the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) codes for common otologic conditions. Among 85 827 weighted pediatric inpatient discharges with ICD-10-CM codes for common otologic conditions, 213 underwent TT placement.
