Introduction: The Precision Medicine Program (PMP) at the University of Florida (UF) focuses on advancing pharmacogenomics (PGx) to improve patient care.

Methods: The UF PMP, in collaboration with the UF Health Pathology Laboratory (UFHPL), utilized Health Level Seven (HL7) standards to integrate PGx data into Epic's Genomic Module to enhance the management and utilization of PGx data in clinical practice.

Results: A key feature of the Genomic Module is the introduction of genomic indicators-innovative tools that flag actionable genetic information directly within the electronic health record (EHR).

Metaplastic breast cancer (MpBC) is a highly chemoresistant subtype of breast cancer with no standardized therapy options. A clinical study in anthracycline-refractory MpBC patients suggested that nitric oxide synthase (NOS) inhibitor NG-monomethyl-l-arginine (L-NMMA) may augment anti-tumor efficacy of taxane. We report that NOS blockade potentiated response of human MpBC cell lines and tumors to phosphoinositide 3-kinase (PI3K) inhibitor alpelisib and taxane.

Delirium is an acute decline or fluctuation in attention, awareness, or other cognitive function that can lead to serious adverse outcomes. Despite the severe outcomes, delirium is frequently unrecognized and uncoded in patients' electronic health records (EHRs) due to its transient and diverse nature. Natural language processing (NLP), a key technology that extracts medical concepts from clinical narratives, has shown great potential in studies of delirium outcomes and symptoms.

Pentatomomorphan bugs can form symbiotic associations with bacteria belonging to the supergenus . This relationship has become a model for understanding environmental symbiont acquisition. Host insects can utilize various symbiont strains from across ; however, host colonization success and benefits conferred vary by bacterial clade.

Article Synopsis
  • The opioid crisis has evolved into a global issue affecting various socioeconomic and cultural areas, with traditional treatment methods proving insufficient.
  • A narrative review was conducted using multiple databases to explore the complex factors contributing to this epidemic, acknowledging the potential for bias in article selection.
  • Despite some progress with Opioid Substitution Therapy, U.S. overdose deaths remain alarmingly high and are projected to increase; the authors suggest a need for a new treatment approach that targets brain neurotransmitter systems for better management.

Introduction: Recent literature suggests pain management and sedation in ED patients after rapid sequence intubation are done inconsistently, which impacts patient outcomes negatively. The purpose of this study is to compare rates and timing of post-intubation analgesia and sedation before and after an ED pharmacy practice improvement intervention.

Methods: We conducted a retrospective study of adult ED patients intubated over an 18-month period.

Article Synopsis
  • - Pathogenic hantaviruses, carried by asymptomatic rodents worldwide, can spill over to humans causing severe diseases, but there are no approved treatments or vaccines available for these infections.
  • - Recent studies are exploring how these rodents can persistently host dangerous viruses without getting sick, focusing on two main ideas: muted immune responses in reservoir cells and the viruses' ability to evade immune detection.
  • - Research showed that while human cells respond robustly to hantavirus infections, rat endothelial cells do not activate antiviral responses when infected with their native hantavirus (SEOV), suggesting that efficient viral replication might help these cells avoid triggering immune defenses.

Angiotensin II (AngII) regulates cerebral circulation and binds with a similar affinity to AT and AT receptors. Biased AT agonists, such as TRV027, which are able to selectively activate β-arrestin while blocking the G pathway, appear promising as new therapeutics. New pharmacological tools are needed to further explore the impact of biased AT agonists on cells or tissues, such as the cerebral vessels.

OnabotulinumtoxinA (onabotA) is approved in the US for 12 therapeutic indications. Real-world data on onabotA multi-indication use are limited, often leading to delayed or reduced treatment. This study provides real-world evidence on the safety of onabotA when treating multiple indications concomitantly.

Introduction: In 2021, the USPSTF lowered the recommended age of colorectal cancer (CRC) screening initiation from 50 to 45 years. This study assessed clinician response to the updated guideline in a major health system.

Methods: This was a retrospective cohort study of average-risk, CRC screening-naïve adults aged 45-50 years with a primary care appointment between July 2018 and February 2023.

In the search for more sustainable remediation strategies for PAH-contaminated soils, an integrated application of thermal remediation and bioremediation (TEB) may allow the use of less impacting temperatures by associating heating to biological degradation. However, the influence of heating on soil microbiota remains poorly understood, especially in soils from tropical regions. This work investigated the effects of low-temperature heating on creosote-contaminated soil bacteria.

Introduction: Autonomy during residency is crucial to the training and development of competent surgeons. An essential component of this process is the 'teaching assistant (TA)' case, an indispensable opportunity for residents to gain confidence and hone intraoperative skills. However, high-quality data on the volume and diversity of cases that graduates perform are scarce.

Article Synopsis
  • Genetic variations in specific genes are linked to differences in lipid metabolism and risks for cardiovascular and neurodegenerative diseases, but previous studies mainly focused on European populations and didn't extensively consider sex or ancestry differences.
  • This study analyzed genetic data from 181,880 participants across seven ancestry groups to identify associations with various health conditions, specifically looking at phenotypes related to Alzheimer's disease risk.
  • The findings revealed significant associations with conditions like hyperlipidemia and Alzheimer's, highlighting differences in these risks based on sex and ancestry, while also noting that there were some unique associations in specific ancestry groups.

Article Synopsis
  • * The study analyzed tissues from 97 patients with symptomatic obstructive HCM through RNA-sequencing and mass spectrometry, revealing significant differences in gene and protein expressions between males and females, though overall profiles were similar.
  • * Findings indicate that HCM females show greater downregulation of hypertrophy pathways and have more differentially expressed proteins compared to control females than what is observed in males, highlighting biologically relevant sex-specific differences in disease mechanisms.

Though surface water quality has been monitored in southern Peru over the past and current century, it has been implemented by multiple organizations. The data lacks a centralized repository and access requires logistical and temporal hurdles associated with official requests. A substantial portion of the data has not been quality assured and is in difficult-to-access formats such as scanned PDF documents.

Introduction: Informed decisions to enrol in the clinical investigations of Alzheimer's disease and related dementias (ADRD) require careful consideration of complex risks and uncertain benefits. Decisions regarding whether to receive information about biomarker status are complicated by lack of scientific consensus regarding biomarkers as surrogate endpoints for Alzheimer's disease and how information about individual risk should be evaluated and shared with research participants. This study aims to establish stakeholder consensus regarding ethically optimal approaches to sharing individual results with ADRD research participants.

Dynamic changes in protein glycosylation impact human health and disease progression. However, current resources that capture disease and phenotype information focus primarily on the macromolecules within the central dogma of molecular biology (DNA, RNA, proteins). To gain a better understanding of organisms, there is a need to capture the functional impact of glycans and glycosylation on biological processes.

Hospital-acquired falls are a continuing clinical concern. The emergence of advanced analytical methods, including NLP, has created opportunities to leverage nurse-generated data, such as clinical notes, to better address the problem of falls. In this nurse-driven study, we employed an iterative process for expert manual annotation of RNs clinical notes to enable the training and testing of an NLP pipeline to extract factors related to falls.
