Variability in performance of genetic-enhanced DXA-BMD prediction models across diverse ethnic and geographic populations: A risk prediction study.

PLoS Med

August 2024

Tulane Center of Biomedical Informatics and Genomics, Deming Department of Medicine, School of Medicine, Tulane University, New Orleans, Louisiana, United States of America.

Background: Osteoporosis is a major global health issue, weakening bones and increasing fracture risk. Dual-energy X-ray absorptiometry (DXA) is the standard for measuring bone mineral density (BMD) and diagnosing osteoporosis, but its costliness and complexity impede widespread screening adoption. Predictive modeling using genetic and clinical data offers a cost-effective alternative for assessing osteoporosis and fracture risk.

Precise Positioning in Nitrogen Fertility Sensing in Maize ( L.).

Sensors (Basel)

August 2024

Louisiana State University Agriculture Center, School of Plant, Environmental and Soil Sciences, Baton Rouge, LA 70803, USA.

This study documented the contribution of precise positioning involving a global navigation satellite system (GNSS) and a real-time kinematic (RTK) system in unmanned aerial vehicle (UAV) photogrammetry, particularly for establishing the coordinate data of ground control points (GCPs). Without augmentation, GNSS positioning solutions are inaccurate and pose a high degree of uncertainty if such data are used in UAV data processing for mapping. The evaluation included a comparative assessment of sample coordinates involving RTK and an ordinary GPS device and the application of precise GCP data for UAV photogrammetry in field crop research, monitoring nitrogen deficiency stress in maize.

CCL28 modulates neutrophil responses during infection with mucosal pathogens.

Elife

August 2024

Division of Host-Microbe Systems & Therapeutics, Department of Pediatrics, University of California, San Diego, La Jolla, United States.

The chemokine CCL28 is highly expressed in mucosal tissues, but its role during infection is not well understood. Here, we show that CCL28 promotes neutrophil accumulation in the gut of mice infected with and in the lung of mice infected with . Neutrophils isolated from the infected mucosa expressed the CCL28 receptors CCR3 and, to a lesser extent, CCR10, on their surface.

Over the past 2 decades, biologists have come to appreciate that hybridization, or genetic exchange between distinct lineages, is remarkably common-not just in particular lineages but in taxonomic groups across the tree of life. As a result, the genomes of many modern species harbor regions inherited from related species. This observation has raised fundamental questions about the degree to which the genomic outcomes of hybridization are repeatable and the degree to which natural selection drives such repeatability.

  • Racial disparities in health outcomes for elderly patients undergoing surgical aortic valve replacement (SAVR) have not been well studied, especially among different racial groups like White, African American, and Hispanic patients.
  • Data from over 400,000 patients revealed that, although overall in-hospital mortality decreased, African Americans faced significantly higher risks of mortality, complications like cardiogenic shock and acute kidney injury, and required more invasive medical support compared to White patients.
  • The study highlights persistent racial inequalities in health outcomes despite improvements in in-hospital mortality among geriatric patients undergoing SAVR, indicating the need for targeted interventions to address these disparities.

Objectives: Rapid response teams (RRTs) can improve outcomes in both adult and pediatric hospitals. Most pediatric hospitals have RRT-type systems; however, little is known about stakeholders' perspectives regarding how to optimize RRT quality and efficiency. We aimed to better understand multidisciplinary stakeholder perspectives on how to improve the RRT process.

Objective: To evaluate the hypothesis that anthropometric dimensions derived from a person's manifold-regression predicted three-dimensional (3D) humanoid avatar are accurate when compared to their actual circumference, volume, and surface area measurements acquired with a ground-truth 3D optical imaging method. Avatars predicted using this approach, if accurate with respect to anthropometric dimensions, can serve multiple purposes including patient body composition analysis and metabolic disease risk stratification in clinical settings.

Methods: Manifold regression 3D avatar prediction equations were developed on a sample of 570 adults who completed 3D optical scans, dual-energy X-ray absorptiometry (DXA), and bioimpedance analysis (BIA) evaluations.

Article Synopsis
  • The COVID-19 pandemic distinctly affected mental health across different populations, revealing pre-existing inequalities and new recovery challenges.
  • A survey conducted in Louisiana during summer 2020 examined the impact of the pandemic on the well-being of 986 Black and White adults, focusing on factors like social support and resilience.
  • Findings indicated that while Black individuals faced greater pandemic-related stress and lower protective factors, both groups showed similar general well-being, and social support, resilience, and social cohesion were found to be vital protective factors against mental health declines.

Surg Radiol Anat

October 2024

Department of Neurosurgery, Clinical Neuroscience Research Center, Tulane University School of Medicine, 131 S. Robertson St. Suite 1300, New Orleans, LA, 70112, USA.

Article Synopsis
  • The xiphoid process (XP) in humans, considered an anatomical variant, was studied to better understand its morphology and cartilage presence.
  • A study using twenty embalmed cadaveric sterna revealed that 85% of XPs contained cartilage, classified into four types based on bone and cartilage proportions.
  • The findings suggest that previous research may have misjudged the XP's size and emphasizes the importance of recognizing xiphoidal cartilage as a normal anatomical feature.

A Simplified Model for the Study of Film-Boiling Droplet Motion on Microscale Ratchets.

Appl Mech (Basel)

March 2024

McCoy College of Science, Mathematics & Engineering, Midwestern State University, a Member of the Texas Tech University System, Wichita Falls, TX 76308, USA.

In this work, we explore a simplified model based on both analytical and computational methods for the study of film-boiling droplet motion on microscale ratchets. We consider a specific ratchet design with the length periods and depth of ratchets much smaller than the size of the droplet. We conclude based on our modeling that for the ratchet configuration considered in this paper, the conduction within the vapor film is the dominant means of heat transfer in comparison with convection and radiation.

Louisiana Animal Disease Diagnostic Laboratory & Department of Pathobiological Sciences, School of Veterinary Medicine, Louisiana State University, Baton Rouge LA, USA.

Here we describe a case of fatal amebic gastritis associated with infection in an 11-mo-old Linnaeus's two-toed sloth (). The sloth had a history of weight loss and intermittent diarrhea for 18 d, and subsequently died despite empirical treatment. Postmortem findings included emaciation, gastric dilation with fluid content, and fibrinonecrotic gastritis with intralesional amebic trophozoites and cysts in the glandular region of the fundus.

Canine osteosarcoma (OSA) is a malignancy that has been shown to modulate the host immune system. Macrophage colony-stimulating factor (M-CSF; CSF1) and interleukin-34 (IL-34; IL34) are both ligands of colony stimulating factor 1 receptor (CSF-1R), and may play a role in the pathogenesis of a variety of human cancers, including OSA. This study aimed to, (1) assess M-CSF and IL-34 expression in canine OSA cell lines and tissue samples, and (2) determine any correlations between M-CSF and IL-34 expression and immune cell infiltrates within canine OSA tissues.
