Delirium Management Quality Improvement Project to Improve Awareness and Screening in a Medical ICU.

Nurs Rep

December 2024

Division of Pulmonary, Critical Care and Sleep Medicine, UC San Diego Health, La Jolla, CA 92093, USA.

Article Synopsis
  • Delirium is common in critical illness, but inconsistent detection and prevention in ICUs exist due to inadequate provider education and practice gaps.
  • A quality improvement project involved distributing CAM-ICU pocket cards to nurses, conducting educational lectures, and demonstrating delirium detection to enhance awareness and application of evidence-based prevention strategies.
  • The initiative resulted in a significant increase in CAM-ICU documentation and a reduction in benzodiazepine use among mechanically ventilated patients, showcasing the effectiveness of interdisciplinary education in improving delirium care standards in ICUs.

Evidence of unintended introductions of species into native habitats has become increasingly prevalent in California. If not managed adequately, species can become devastating agricultural and forest plant pathogens. Additionally, California's natural areas, characterized by a Mediterranean climate and dominated by chaparral (evergreen, drought-tolerant shrubs) and oak woodlands, lack sufficient baseline knowledge on biology and ecology, hindering effective management efforts.

December 2024

Laboratorio de Biorremediación, Departamento de Ciencias Forestales, Facultad de Ciencias Agropecuarias y Medioambiente, Universidad de la Frontera, Casilla 54-D, Temuco 4811230, Chile.

The use of living organisms to treat human by-products, such as residual sludge, has gained interest in the last years. Fungi have been used for bioremediation and improving plant performance in contaminated soils. We investigated the impact of the mycorrhizal fungus (MF) and the saprophytic fungus (SF) on the survival and growth of seedlings cultivated in a sandy substrate supplemented with residual sludge.

Many factors contribute to the development and the progression of Multiple Sclerosis (MS), including Human Leukocyte Antigen (HLA) molecules. Some of them are considered as predisposing, like DRB1*15, DRB1*13, DRB1*03, DRB1*04, DQB1*06, DQB1*02, while HLA A2, HLA B44, DRB1*11, and DRB1*12 are rather considered as protective. Data about such associations in the Moroccan population remain unknown.

Hepatopulmonary syndrome (HPS), defined by the presence of pulmonary vascular dilatations that cause right-to-left transpulmonary shunting of venous blood with a consequential increase in the alveolar-arterial oxygen gradient, is a relatively frequent complication of chronic liver disease. While orthotopic liver transplantation (OLT) is indicated and often curative in HPS patients with end-stage liver disease (ESLD), little is known about the peri- and post-operative-period risks of CVA in OLT recipients with HPS. : We report a case series of five non-consecutive OLT recipients with HPS who developed ischemic and/or hemorrhagic CVAs during or shortly after OLT, raising concern that the risks of neurological complications remain increased even after OLT.

On the Differential and the Integral Value of Information.

Entropy (Basel)

January 2025

Institute of Chemistry, The Hebrew University of Jerusalem, Jerusalem 91904, Israel.

A quantitative expression for the value of information within the framework of information theory and of the maximal entropy formulation is discussed. We examine both a local, differential measure and an integral, global measure for the value of the change in information when additional input is provided. The differential measure is a potential and as such carries a physical dimension.

Structural maintenance of chromosome-1A (SMC1A) is overexpressed in various malignancies including triple-negative breast cancer (TNBC). As a core component of the cohesin complex, SMC1A was initially recognized for its involvement in chromosomal cohesion and DNA-repair pathways. However, recent studies have unveiled its pivotal role in epithelial-mesenchymal transition (EMT), metastasis, and chemo- and radio-resistance in cancer cells.

GV1001, hTERT Peptide Fragment, Prevents Doxorubicin-Induced Endothelial-to-Mesenchymal Transition in Human Endothelial Cells and Atherosclerosis in Mice.

Cells

January 2025

The Shapiro Family Laboratory of Viral Oncology and Aging Research, UCLA School of Dentistry, University of California, 714 Tiverton Ave, Los Angeles, CA 90095, USA.

Doxorubicin is a highly effective anticancer agent, but its clinical use is restricted by severe side effects, including atherosclerosis and cardiomyopathy. These complications are partly attributed to doxorubicin's ability to induce endothelial-to-mesenchymal transition (EndMT) in vascular endothelial cells, a critical process in the initiation and progression of atherosclerosis and cardiomyopathy. GV1001, a multifunctional peptide with anti-inflammatory, anti-cancer, antioxidant, and anti-Alzheimer's properties, has demonstrated inhibition of EndMT.

Natural Killer Cell-Secreted IFN-γ and TNF-α Mediated Differentiation in Lung Stem-like Tumors, Leading to the Susceptibility of the Tumors to Chemotherapeutic Drugs.

Cells

January 2025

Division of Oral Biology and Medicine, The Jane and Jerry Weintraub Center for Reconstructive Biotechnology, University of California School of Dentistry, 10833 Le Conte Ave, Los Angeles, CA 90095, USA.

We demonstrate that natural killer (NK) cells induce a higher cytotoxicity against lung cancer stem-like cells (hA549) compared to differentiated lung cancer cell lines (H292). The supernatants from split-anergized NK cells (IL-2 and anti-CD16 mAb-treated NK cells) induced differentiation in hA549. Differentiated lung cancer cell line (H292) and NK cells differentiated hA549 expressed reduced NK cell-mediated cytotoxicity but expressed higher sensitivity to chemotherapeutic drugs.

Chronic Rapamycin Prevents Electrophysiological and Morphological Alterations Produced by Conditional Pten Deletion in Mouse Cortex.

Cells

January 2025

IDDRC, Jane and Terry Semel Institute for Neuroscience and Human Behavior, David Geffen School of Medicine, University of California Los Angeles, Los Angeles, CA 90095, USA.

Article Synopsis
  • Abnormalities in the mTOR pathway are linked to various brain disorders, affecting synaptic and membrane excitability in neurons.
  • Using a mouse model with Pten deletion, the study found that CPNs had increased membrane size and reduced neuronal firing, which could be reversed with rapamycin treatment.
  • Chronic rapamycin not only prevented changes in Pten mice but also altered the membrane properties of normal mice, suggesting potential treatments for neurological disorders like epilepsy and autism associated with mTOR dysfunction.

iPSC Technology Revolutionizes CAR-T Cell Therapy for Cancer Treatment.

Bioengineering (Basel)

January 2025

Department of Microbiology, Immunology & Molecular Genetics, University of California, Los Angeles, CA 90095, USA.

Chimeric Antigen Receptor (CAR)-engineered T (CAR-T) cell therapy represents a highly promising modality within the domain of cancer treatment. CAR-T cell therapy has demonstrated notable efficacy in the treatment of hematological malignancies, solid tumors, and various infectious diseases. However, current CAR-T cell therapy is autologous, which presents challenges related to high costs, time-consuming manufacturing processes, and the necessity for careful patient selection.

Mary and Steve Wen Cardiovascular Division, Department of Medicine, University of California, Los Angeles. (W.F., N.D.W.).

Background: Lp(a; Lipoprotein[a]) is a predictor of atherosclerotic cardiovascular disease (ASCVD); however, there are few algorithms incorporating Lp(a), especially from real-world settings. We developed an electronic health record (EHR)-based risk prediction algorithm including Lp(a).

Methods: Utilizing a large EHR database, we categorized Lp(a) cut points at 25, 50, and 75 mg/dL and constructed 10-year ASCVD risk prediction models incorporating Lp(a), with external validation in a pooled cohort of 4 US prospective studies.

Department of Population and Public Health Sciences, University of Southern California, Los Angeles, California, USA.

Objective: This study examines perceptions of changes in intimate relationships among partnered, immigrant women in New York City during the first year of the COVID-19 pandemic. We pay close attention to how structural oppression, particularly related to undocumented immigration status, shaped women's experiences with their intimate partners during a period of social upheaval.

Background: COVID-19 has exacerbated many existing structural inequities and subsequent stressors that have been shown to have an adverse effect on intimate relationships, including increased economic instability and mental health distress.
