Using intravascular catheter dressing audit data, we evaluated factors associated with non-compliant dressing. Male sex and gauze dressing had a higher risk of non-compliant dressing; presence of one or more lumens infusing, central venous catheter, PICC line, implantable port and contact precautions were associated with a lower risk of non-compliant dressing.

Quantum-State Renormalization in Semiconductor Nanoparticles.

ACS Nano

December 2024

Department of Chemistry and Institute of Materials Science and Engineering, Washington University in Saint Louis, Saint Louis, Missouri 63130, United States.

A single photoexcited electron-hole pair within a polar semiconductor nanocrystal (SNC) alters the charge screening and shielding within it. Perturbations of the crystal lattice and of the valence and conduction bands result, and the quantum-confinement states in a SNC shift uniquely with a dependence on the states occupied by the carriers. This shifting is termed quantum-state renormalization (QSR).

Memory updating and the structure of event representations.

Trends Cogn Sci

December 2024

Department of Psychological & Brain Sciences, Washington University in Saint Louis, Saint Louis, MO 63130, USA. Electronic address:

People form memories of specific events and use those memories to make predictions about similar new experiences. Living in a dynamic environment presents a challenge: How does one represent valid prior events in memory while encoding new experiences when things change? There is evidence for two seemingly contradictory classes of mechanism: One differentiates outdated event features by making them less similar or less accessible than updated event features. The other integrates updated features of new events with outdated memories, and the relationship between them, into a structured representation.

CNS-CLIP: Transforming a Neurosurgical Journal Into a Multimodal Medical Model.

Neurosurgery

December 2024

Department of Neurological Surgery, NYU Langone Health, New York, New York, USA.

Background And Objectives: Classical biomedical data science models are trained on a single modality and aimed at one specific task. However, the exponential increase in the size and capabilities of the foundation models inside and outside medicine shows a shift toward task-agnostic models using large-scale, often internet-based, data. Recent research into smaller foundation models trained on specific literature, such as programming textbooks, demonstrated that they can display capabilities similar to or superior to large generalist models, suggesting a potential middle ground between small task-specific and large foundation models.

Introduction: Shivering affects 52 % of patients undergoing caesarean delivery under neuraxial anaesthesia. Despite extensive research focused on its prevention, there is still no consensus regarding optimal pharmacological treatment. This systematic review and network meta-analysis aims to compare available intravenous treatments of perioperative shivering in patients undergoing caesarean delivery under neuraxial anaesthesia.

Objective: Though caffeine use during pregnancy is common, its longitudinal associations with child behavioral and physical health outcomes remain poorly understood. Here, we estimated associations between prenatal caffeine exposure, body mass index (BMI), and behavior as children enter adolescence.

Method: Longitudinal data and caregiver-reported prenatal caffeine exposure were obtained from the ongoing Adolescent Brain and Cognitive Development (ABCD) Study, which recruited 11,875 children aged 9-11 years at baseline from 21 sites across the United States starting June 1, 2016.

The objective of this study was to assess fibrinogen (FIB) co-modified with citrulline (CIT) and/or malondialdehyde-acetaldehyde (MAA) initiates macrophage-fibroblast interactions leading to extracellular matrix (ECM) deposition that characterizes rheumatoid arthritis-associated interstitial lung disease (RA-ILD). Macrophages (Mϕ) were stimulated with native-FIB, FIB-CIT, FIB-MAA or FIB-MAA-CIT. Supernatants (SN) (Mϕ-SN [U-937-derived] or MϕP-SN [PBMC-derived]) or direct antigens were co-incubated with human lung fibroblasts (HLFs).

To identify circRNAs associated with Parkinson's disease (PD) we leveraged two of the largest publicly available studies with longitudinal clinical and blood transcriptomic data. We performed a cross-sectional study utilizing the last visit of each participant (N = 1848), and a longitudinal analysis that included 1166 participants with at least two time points. We identified 192 differentially expressed circRNAs, with effects that were sustained during disease, in mutation carriers, and diverse ancestry.

Regeneration of missing body parts can be observed in diverse animal phyla, but it remains unclear to which extent these capacities rely on shared or divergent principles. Research into this question requires detailed knowledge about the involved molecular and cellular principles in suitable reference models. By combining single-cell RNA sequencing and mosaic transgenesis in the marine annelid Platynereis dumerilii, we map cellular profiles and lineage restrictions during posterior regeneration.

Article Synopsis
  • A study examined how inflammation might contribute to chronic pain and fatigue in older adults by analyzing the relationship between inflammatory markers (IL-6, CRP, TNFα) and reported symptoms over time.
  • Researchers collected blood samples and health assessments from participants in the Saint Louis Personality and Aging (SPAN) study, focusing on correlations and potential confounding factors.
  • Findings indicated higher levels of IL-6 and CRP were linked to increased pain and fatigue; moreover, CRP was specifically predictive of future fatigue, while pain and fatigue also influenced inflammation levels over the studied period.

Deciphering glioblastoma: Unveiling imaging markers for predicting MGMT promoter methylation status.

Curr Probl Cancer

November 2024

Mallinckrodt Institute of Radiology, School of Medicine, Washington University in Saint Louis, St. Louis, MO, United States. Electronic address:

Glioblastoma, the most common primary malignant tumor of the central nervous system in adults, is also among the most lethal. Despite a comprehensive treatment approach which utilizes surgery and postoperative chemoradiation, prognosis typically remains dismal. However certain epigenetic modifications, such as methylation of the MGMT promoter, have been proven to correlate with improved post-treatment outcomes.

Article Synopsis
  • The study investigates the effects of testosterone therapy (TT) on men with metabolic dysfunction-associated steatotic liver disease (MASLD), aiming to see if it can slow down disease progression.
  • A systematic review analyzed 9 studies, including randomized and non-randomized trials, which showed that TT consistently reduced liver steatosis and fibrosis compared to no treatment.
  • The findings suggest TT could be an effective treatment for men with MASLD and low testosterone, but more rigorous, large-scale trials are necessary for conclusive results.

We aimed to identify plasma cell-free transcripts (cfRNA) associated with Parkinson's disease (PD) that also have a high predictive value to differentiate PD from healthy controls. Leveraging two independent populations from two different movement disorder centers we identified 2,188 differentially expressed cfRNAs after meta-analysis. The identified transcripts were enriched in PD relevant pathways, such as PD (p=9.

Article Synopsis
  • SARS-CoV-2 infects host cells by using its spike protein's receptor binding domain (RBD) to bind to the ACE2 receptor, which is crucial for the virus's entry into cells.
  • The ACE2 receptor consists of several domains, with the peptidase domain (PD) being essential for its function as a viral receptor; however, the receptor needs to be close to the cell membrane for effective infection.
  • Researchers found that engineered proteins targeting the RBD can influence whether cells are susceptible or resistant to the virus, indicating potential paths for antiviral therapies.

Fission-fusion social systems allow individuals to make flexible choices about where, with whom, and in what contexts to spend their time in response to competing social and ecological pressures. The ability for fission-fusion societies to support individual behavioral strategies that vary across contexts has been suggested, but the potential function of such context-specific social choices remains largely understudied. We adopted the concept of social niche construction to explore possible differences in social complexity at the individual and group level across feeding contexts.
