Assessing Attitudes and Perceptions of High-Risk, Low-Resource Communities Towards Cardiopulmonary Resuscitation and Public-Access Defibrillation.

Layperson cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use are vital for improving survival rates after out-of-hospital cardiac arrest (OHCA), yet their application varies by community demographics. We evaluated the concerns and factors influencing willingness to perform CPR and use AEDs among laypersons in high-risk, low-resource communities. From April 2022 to March 2024, laypersons in Northern Manhattan's Community District 12 completed surveys assessing their attitudes toward CPR and AED use before attending Hands-Only CPR training.

We describe and discuss three learning activities, the associated challenges and lessons learnt, and the current position. Given the encompassing nature of environmental and health interactions, we aimed for multilayer immersive experiences using a range of pedagogical approaches.

When common cognitive biases impact debriefing conversations.

Healthcare debriefing is a cognitively demanding conversation after a simulation or clinical experience that promotes reflection, underpinned by psychological safety and attention to learner needs. The process of debriefing requires mental processing that engages both "fast" or unconscious thinking and "slow" intentional thinking to be able to navigate the conversation. "Fast" thinking has the potential to surface cognitive biases that impact reflection and may negatively influence debriefer behaviors, debriefing strategies, and debriefing foundations.

Dynamic CT features of scapholunate instability during the wrist extension to flexion-An in vivo study.

Purpose: This biomechanical study aimed to assess the change in the radioscaphoid and the radiolunate angles during wrist extension to flexion in scapholunate instability compared to the healthy wrist.

Methods: Dynamic CT scans of 19 participants with no history of wrist pathology and 19 patients with scapholunate instability without degenerative changes were selected. Motion sequence studied was wrist extension to flexion.

SHEA practice update: infection prevention and control (IPC) in residential facilities for pediatric patients and their families.

In 2011, the Society for Healthcare Epidemiology of America (SHEA) and Ronald McDonald House Charities® (RMHC®) established a formal collaboration to develop the first IPC guideline. Both organizations agreed that RMH programs staff and other organizations operating similar programs would benefit from a standardized approach. In 2023, the collaboration was re-established to revise and update the original IPC guideline.

Unacceptable Behaviors Towards Health Professional Clinical Students: Protocol For a Mixed-Methods Study.

Background And Aims: Previous studies describe the occurrence of unacceptable behaviors reported by students pursuing health professional education in Aotearoa, New Zealand and across the globe. These include, but are not limited to, experiences of verbal abuse, sexual harassment, and discrimination based on race/ethnicity, religious beliefs, gender, and sexual orientation. University of Otago teaching staff across the various health professional programs often receive anecdotal reports of these phenomena from their clinical students.

From Simulation to Bedside: The Journey to Provide Equitable Patient Care.

Simulation-based education (SBE) has revolutionized health care training by enhancing skills and addressing systemic issues. This article explores how SBE can bridge the gap between recognizing health care disparities and implementing actionable steps to address them. The immersive nature of SBE, combined with structured debriefing, sets the foundation for a "brave space" that fosters critical discussions on crucial topics, such as health equity.

Risk-stratified treatment for drug-susceptible pulmonary tuberculosis.

The Phase 3 randomized controlled trial, TBTC Study 31/ACTG A5349 (NCT02410772) demonstrated that a 4-month rifapentine-moxifloxacin regimen for drug-susceptible pulmonary tuberculosis was safe and effective. The primary efficacy outcome was 12-month tuberculosis disease free survival, while the primary safety outcome was the proportion of grade 3 or higher adverse events during the treatment period. We conducted an analysis of demographic, clinical, microbiologic, radiographic, and pharmacokinetic data and identified risk factors for unfavorable outcomes and adverse events.

Stromal reprogramming overcomes resistance to RAS-MAPK inhibition to improve pancreas cancer responses to cytotoxic and immune therapy.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy that is often resistant to therapy. An immune suppressive tumor microenvironment (TME) and oncogenic mutations in have both been implicated as drivers of resistance to therapy. Mitogen-activated protein kinase (MAPK) inhibition has not yet shown clinical efficacy, likely because of rapid acquisition of tumor-intrinsic resistance.

Mutation Clonal Hierarchy in Acute Myeloid Leukemia.

Mutations in protein tyrosine phosphatase non-receptor type 11 ( ) have been considered late acquired mutations in acute myeloid leukemia (AML) development. To interrogate the ontogeny of mutations, we utilized single-cell DNA sequencing and identified that mutations can occur as initiating events in some AML patients when accompanied by strong oncogenic drivers, commonly mutations. The co-driver role of mutations was confirmed in a novel murine model that exhibits an AML phenotype with early expansion of a diverse set of variably differentiated myeloid cells that engrafted into immunodeficient and immunocompetent mice.

Integrated Stepped Alcohol Treatment With Contingency Management for Unhealthy Alcohol Use Among People With HIV: A Randomized Controlled Trial.

Background: We examined the impact of integrated stepped alcohol treatment with contingency management (ISAT + CM) on alcohol abstinence among people with HIV (PWH) and unhealthy alcohol use.

Methods: In this multisite 24-week trial, we randomized PWH reporting untreated unhealthy alcohol use and with phosphatidylethanol (PEth) >20 ng/mL to receive ISAT+CM or treatment as usual (TAU). Intervention : Step 1 : Social worker-delivered CM; Step 2 : Addiction physician management plus motivational enhancement therapy.

Emergency Medical Service Transport Time in Rural Farm and Non-Farm Pediatric Trauma.

Objectives: Pediatric farm injuries tend to be more severe and have poorer outcomes compared to injuries sustained in non-farm settings. Timely emergency medical service (EMS) response and transport to definitive care is crucial for optimizing outcomes for trauma patients. We aimed to determine if pediatric farm injuries were associated with longer EMS response and transport times compared to pediatric non-farm injuries in rural communities.

Cortical Thickness Correlates of Go/No-go and Motor Sequencing in Mild Cognitive Impairment and Suspected Alzheimer Disease Dementia.

Background: While the cognitive hallmark of typical Alzheimer disease (AD) is impaired memory consolidation, increasing evidence suggests that the frontal lobes and associated executive functions are also impacted.

Objective: We examined two neurobehavioral executive function tasks and associations with cortical thickness in patients diagnosed with mild cognitive impairment (MCI), suspected AD dementia, and a healthy control group.

Methods: First, we compared group performances on a go/no-go (GNG) task and on Luria's Fist-Edge-Palm (FEP) motor sequencing task.

Caregiver Intent and Willingness to Accept COVID-19 Vaccine in the Pediatric Emergency Department.

Background: While COVID-19 vaccine (CV) acceptance is improving, little is known about parental acceptance of CV in the pediatric emergency department (PED).

Objectives: The aims of the study are to assess rates of CV uptake among eligible children presenting to the PED, describe caregiver willingness to accept CV in the PED, and assess potential ED-based interventions to increase CV acceptance.

Methods: We surveyed caregivers of 384 children aged ≥6 months presenting to the PED for minor illness/injury.

Disruption in cortisol synchrony and pair-dissolution in the serially monogamous convict cichlid (Amatitlania nigrofasciata).

Endocrine synchronization is a biological process often associated with social bonding. The mechanisms that mediate this process have been well studied in many vertebrate clades with evolved complex social behaviors. However, studies focusing on such processes in the less neurologically complex teleost clade are surprisingly lacking.

Pyrazinamide Safety, Efficacy, and Dosing for Treating Drug-Susceptible Pulmonary Tuberculosis: A Phase 3, Randomized Controlled Clinical Trial.

Optimizing pyrazinamide dosing is critical to improve treatment efficacy while minimizing toxicity during tuberculosis treatment. Study 31/AIDS Clinical Trials Group A5349 represents the largest phase 3 randomized controlled therapeutic trial to date for such an investigation. We sought to report pyrazinamide pharmacokinetic parameters, risk factors for lower pyrazinamide exposure, and relationships between pyrazinamide exposure and efficacy and safety outcomes.

Empirical assessment of wounds among people who use substances.

Background: Wounds are a significant source of morbidity among people who use substances (PWUS). This project sought to identify the incidence and severity of wounds among PWUS in the South Bronx, a region of New York City with one of the highest morbidities of substance use disorder.

Methods: This study recruited PWUS within the past 30 days.

Does smoking cessation reduce other substance use, psychiatric symptoms, and pain symptoms? Results from an emulated hypothetical randomized trial of US veterans.

Background: Quitting smoking may lead to improvement in substance use, psychiatric symptoms, and pain, especially among high-risk populations who are more likely to experience comorbid conditions. However, causal inferences regarding smoking cessation and its subsequent benefits have been limited.

Methods: We emulated a hypothetical open-label randomized control trial of smoking cessation using longitudinal observational data of HIV-positive and HIV-negative US veterans from 2003-2015 in the Veterans Aging Cohort Study.

The Clinical Impact of Hospital-Acquired Adverse Drug Reactions in Older Adults: An Australian Cohort Study.

Introduction: Hospital-acquired adverse drug reactions (HA-ADRs) are common in older adults. However, there is limited knowledge regarding the association between HA-ADRs and adverse clinical outcomes.

Objective: To investigate the incidence and characteristics of HA-ADRs in older adults, and any association with mortality, length of stay, and readmissions.

HOLOTHURIA SCABRA METHANOL EXTRACT INHIBITS CANCER GROWTH THROUGH TGF-β/PI3K/PTEN SIGNALING PATHWAY IN BREAST CANCER MICE MODEL.

Background: Molecules and cytokines can be targeted in cancer therapy. Transforming growth factor-beta (TGF-β) is a cytokine that acts on protein kinase receptors in the plasma membrane. The signaling pathway of TGF-β can trigger the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) pathway, a signal transduction pathway important in cancer growth and development.

Defining the KRAS- and ERK-dependent transcriptome in KRAS-mutant cancers.

How the oncogene drives cancer growth remains poorly understood. Therefore, we established a systemwide portrait of KRAS- and extracellular signal-regulated kinase (ERK)-dependent gene transcription in KRAS-mutant cancer to delineate the molecular mechanisms of growth and of inhibitor resistance. Unexpectedly, our KRAS-dependent gene signature diverges substantially from the frequently cited Hallmark KRAS signaling gene signature, is driven predominantly through the ERK mitogen-activated protein kinase (MAPK) cascade, and accurately reflects KRAS- and ERK-regulated gene transcription in KRAS-mutant cancer patients.

Determining the ERK-regulated phosphoproteome driving KRAS-mutant cancer.

To delineate the mechanisms by which the ERK1 and ERK2 mitogen-activated protein kinases support mutant KRAS-driven cancer growth, we determined the ERK-dependent phosphoproteome in KRAS-mutant pancreatic cancer. We determined that ERK1 and ERK2 share near-identical signaling and transforming outputs and that the KRAS-regulated phosphoproteome is driven nearly completely by ERK. We identified 4666 ERK-dependent phosphosites on 2123 proteins, of which 79 and 66%, respectively, were not previously associated with ERK, substantially expanding the depth and breadth of ERK-dependent phosphorylation events and revealing a considerably more complex function for ERK in cancer.

Radiocarpal and midcarpal kinematics in scapholunate instability: a four-dimensional CT study in vivo.

The distribution of motion between the radiocarpal and midcarpal joints in scapholunate instability is poorly understood. This has potential implications in predicting degenerative changes and in selecting salvage procedures. We studied 19 healthy wrists and 19 wrists with scapholunate instability using dynamic computed tomography during wrist extension to flexion and ulnar to radial deviation.
