Neuroeconomically dissociable forms of mental accounting are altered in a mouse model of diabetes.

Those with diabetes mellitus are at high-risk of developing psychiatric disorders, especially mood disorders, yet the link between hyperglycemia and altered motivation has not been thoroughly explored. Here, we characterized value-based decision-making behavior of a streptozocin-induced diabetic mouse model on Restaurant Row, a naturalistic neuroeconomic foraging paradigm capable of behaviorally capturing multiple decision systems known to depend on dissociable neural circuits. Mice made self-paced choices on a daily limited time-budget, accepting or rejecting reward offers based on cost (delays cued by tone pitch) and subjective value (flavors), in a closed-economy system tested across months.

Preliminary studies for the standardization of a pXRF analyzer ICP-OES for the accurate quantification of Pb in new paint.

Determining lead (Pb) concentrations in new paints using spectroscopic methods such as Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) requires technical expertise, consumables, equipment for method preparation, and instrumentation that can be cost prohibitive and difficult to maintain in low and middle-income countries (LMICs). Although portable X-ray Fluorescence (pXRF) analyzers are less expensive and simple to operate, their inaccuracy has limited their use to screening for the analysis of Pb in new, dried paint. To determine the limits of pXRF analyzers, new paint samples were purchased, dried, homogenized, and analyzed pXRF and ICP-OES.

Optimisation of a novel series of ENaC inhibitors, leading to the selection of the long-acting inhaled clinical candidate ETD001, a potential new treatment for cystic fibrosis.

Cystic Fibrosis (CF) results from the loss of function of the cystic fibrosis transmembrane conductance regulator (CFTR), an ion channel of key importance in the airway epithelia. CFTR helps control optimal hydration of the airways, a crucial requirement for healthy lungs. CFTR modulators have recently been approved as an effective treatment option for many genetic variants of CF.

Effect of group virtual exercise on people with Parkinson's disease: A randomized controlled trial.

Background: For people with Parkinson's disease (PwPD), high-intensity exercise in individual or group format can improve function and quality of life (QoL). Individualized virtual exercise programs have been effective for people with PD, but the feasibility and impact of group exercise in the virtual format has not been investigated.

Purpose: To compare the effect of individual and group virtual exercise on functional mobility and QoL for PwPD.

Objective: To assess the research output of urology residents at top programs and investigate the correlation between medical school research productivity (MRP), research during residency (RRP), and pursuit of academic practice. Further, to characterize trends in MRP before and after the transition to pass/fail scoring of USMLE Step 1.

Methods: Our team previously reported on the PubMed-indexed research productivity of applicants matching into top 50 urology programs.

The Proteolytic Activity of Neutrophil-Derived Serine Proteases Bound to the Cell Surface Arming Lung Epithelial Cells for Viral Defense.

The collaboration between cellular proteases and host cells is pivotal in mounting an effective innate immune defense. Of particular interest is the synergistic interaction between cathepsin G (CatG) and neutrophil elastase (NE), which are proteases secreted by activated neutrophils, and the human alveolar basal epithelial cell line (A549) and the human lung epithelial-like cell line (H1299), because of the potential implications for viral infection. Our study aimed to investigate the binding capacity of CatG and NE on the surface of A549 and H1299 cells through preincubation with purified CatG and NE; thereby, the proteolytic activity could be detected using activity-based probes.

Microsatellite Instability, Tumor Mutational Burden, and Response to Immune Checkpoint Blockade in Patients with Prostate Cancer.

Purpose: Patients with microsatellite instability-high/mismatch repair-deficient (MSI-H/dMMR) and high tumor mutational burden (TMB-H) prostate cancers are candidates for pembrolizumab. We define the genomic features, clinical course, and response to immune checkpoint blockade (ICB) in patients with MSI-H/dMMR and TMB-H prostate cancers without MSI [TMB-H/microsatellite stable (MSS)].

Experimental Design: We sequenced 3,244 tumors from 2,257 patients with prostate cancer.

Treatment for Opioid Use Disorder: Population Estimates - United States, 2022.

In 2022, 81,806 opioid-involved overdose deaths were reported in the United States, more than in any previous year. Medications for opioid use disorder (OUD), particularly buprenorphine and methadone, substantially reduce overdose-related and overall mortality. However, only a small proportion of persons with OUD receive these medications.

Benefits of Aerosolized, Point-of-care, Autologous Skin Cell Suspension (ASCS) for the Closure of Full-thickness Wounds From Thermal and Nonthermal Causes: Learning Curves From the First 50 Consecutive Cases at an Urban, Level 1 Trauma Center.

Objective: To determine the utility of Autologous Skin Cell Suspension (ASCS) in closing full-thickness (FT) defects from injury and infection.

Background: Although ASCS has documented success in closing partial-thickness burns, far less is known about the efficacy of ASCS in FT defects.

Methods: Fifty consecutive patients with FT defects (burn 17, necrotizing infection 13, crush 7, degloving 5, and other 8) underwent closure with the bilayer technique of 3:1 widely meshed, thin, split-thickness skin graft and 80:1 expanded ASCS.

Minimizing higher-order aggregation maximizes iron mobilization by small molecules.

The natural product hinokitiol mobilizes iron across lipid bilayers at low concentrations and restores hemoglobinization in iron transporter protein-deficient systems. But hinokitiol fails to similarly mobilize iron at higher concentrations, limiting its uses in chemical biology and medicine. Here we show that at higher concentrations, hinokitiol:Fe(III) complexes form large, higher-order aggregates, leading to loss of transmembrane iron mobilization.

Neuronal, affective, and sensory correlates of targeted helping behavior in male and female Sprague Dawley rats.

Introduction: Empathic behaviors are driven by the ability to understand the emotional states of others along with the motivation to improve it. Evidence points towards forms of empathy, like targeted helping, in many species including rats. There are several variables that may modulate targeted helping, including sex, sensory modalities, and activity of multiple neural substrates.

Genetic and subjective sensitivity, relationship dynamics, and psychological distress in couples.

Positive and negative aspects of intimate relationships influence mental health and well-being in couples. According to the environmental sensitivity framework, individuals differ in how strongly they are affected by their environment, with some individuals being more or less sensitive to both negative and positive experiences. The present study examined the longitudinal associations between positive and negative relationship dynamics, including marital satisfaction, positive bonding, and negative communication, and psychological distress as well as the extent to which individual differences in genetic and subjective measures of environmental sensitivity moderated the association between relationship dynamics and psychological distress in a sample of couples in the U.

Impact of COVID-19 on Referral Patterns and Service Delivery for an Integrated Behavioral Health Program.

The emergence and rapid spread of COVID-19 led to unprecedented changes for families and systems of care. This study sought to understand the needs of families participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) before and during the pandemic and considers the impact remote service delivery has on access to an integrated behavioral health intervention to support the psychosocial needs of children and caregivers. Needs for referral varied significantly pre- and post-pandemic onset.

Biomarker Inference and the Timing of Next-Generation Sequencing in a Multi-Institutional, Cross-Cancer Clinicogenomic Data Set.

Purpose: Observational clinicogenomic data sets, consisting of tumor next-generation sequencing (NGS) data linked to clinical records, are commonly used for cancer research. However, in real-world practice, oncologists frequently request NGS in search of treatment options for progressive cancer. The extent and impact of this dynamic on analysis of clinicogenomic research data are not well understood.

Racial/ethnic disparities in availability of volunteer unrelated donors for allogeneic transplantation.

Despite the global unrelated donor (URD) registry size, the degree to which URD availability is a transplant barrier is not established. We evaluated the availability of 3,843 URDs requested for 455 diverse adult patients (predominantly with acute leukemia). URDs for non-Europeans were more likely to be domestic and had markedly lower Donor Readiness scores.

Genomic Characterization and Clinical Outcomes of Patients with Peritoneal Metastases from the AACR GENIE Biopharma Collaborative Colorectal Cancer Registry.

Unlabelled: Peritoneal metastases (PM) are common in metastatic colorectal cancer (mCRC). We aimed to characterize patients with mCRC and PM from a clinical and molecular perspective using the American Association of Cancer Research Genomics Evidence Neoplasia Information Exchange (GENIE) Biopharma Collaborative (BPC) registry. Patients' tumor samples underwent targeted next-generation sequencing.

Diabetes alters neuroeconomically dissociable forms of mental accounting.

Those with diabetes mellitus are at high-risk of developing psychiatric disorders, yet the link between hyperglycemia and alterations in motivated behavior has not been explored in detail. We characterized value-based decision-making behavior of a streptozocin-induced diabetic mouse model on a naturalistic neuroeconomic foraging paradigm called Restaurant Row. Mice made self-paced choices while on a limited time-budget accepting or rejecting reward offers as a function of cost (delays cued by tone-pitch) and subjective value (flavors), tested daily in a closed-economy system across months.

Mindfulness Intervention Improves Coping and Perceptions of Children's Behavior among Families with Elevated Risk.

Mindfulness-informed interventions (MIIs) are increasingly common but have not been extensively studied among families with elevated levels of risk (e.g., those involved in child protective services and/or receiving financial assistance).

Substance use typologies among young people experiencing homelessness in seven cities across the United States: A latent class analysis.

Background: Substance use and other health-risk risk factors, including mental health, trauma, and sexual-risk behaviors, often co-occur among youth experiencing homelessness (YEH). The present study aimed to identify subgroups of YEH based on polysubstance use and the linkages to sociodemographic and health-risk characteristics.

Methods: From June 2016 to July 2017, 1,426 YEH (aged 18-26 years) were recruited from seven cities (Houston, Los Angeles, Denver, Phoenix, New York City, St.
