Validation studies and multi-omics analysis of Zhx2 as a candidate quantitative trait gene underlying brain oxycodone metabolite (oxymorphone) levels and behavior.

Sensitivity to the subjective reinforcing properties of opioids has a genetic component and can predict addiction liability of opioid compounds. We previously identified as a candidate gene underlying increased brain concentration of the oxycodone () metabolite oxymorphone () in BALB/cJ () versus BALB/cByJ () females that could increase OXY state-dependent reward. A large structural intronic variant is associated with a robust reduction of Zhx2 expression in J mice, which we hypothesized enhances OMOR levels and OXY addiction-like behaviors.

A Qualitative Evidence Synthesis of Patient and Provider Attitudes Toward Audio-Only Telemental Health Care.

Audio-only (phone) telemental health care can increase access to care, but its lack of nonverbal information may negatively impact care quality as compared to video or in-person visits. The objective of this work was to understand patient and provider attitudes toward phone care via a review of qualitative research. A qualitative evidence synthesis was conducted of peer-reviewed qualitative research published between 2013 and 2023.

Lactate Oxidase Disrupts Lactate-Activated RAS and PI3K Oncogenic Signaling.

LOX was recently shown to inhibit cancer cell proliferation and tumor growth. The mechanism of this inhibition, however, has been exclusively attributed to LOX depletion of TME lactate, a cancer cell energy source, and production of HO, an oxidative stressor. We report that TME lactate triggers the assembly of the lactate receptor hydroxycarboxylic acid receptor 1 (HCAR1)-associated protein complex, which includes GRB2, SOS1, KRAS, GAB1, and PI3K, for the activation of both the RAS and the PI3K oncogenic signaling pathways in breast cancer (BCa) cells.

Association of Patient and Tumor Characteristics With Outcomes in Young Head and Neck Squamous Cell Carcinoma Patients.

Introduction: We retrospectively studied young patients with head and neck squamous cell carcinoma (HNSCC) to identify factors associated with disease-specific survival (DSS).

Methods: Patient and tumor characteristics of patients aged ≤45 who received treatments for non-metastatic HNSCC were collected to identify factors associated with DSS. Proportional hazards regression was applied separately for surgical and non-surgical patients.

Computational models for improving surveillance for the early detection of direct introduction of cassava brown streak disease in Nigeria.

Cassava is a key source of calories for smallholder farmers in sub-Saharan Africa but its role as a food security crop is threatened by the cross-continental spread of cassava brown streak disease (CBSD) that causes high yield losses. In order to mitigate the impact of CBSD, it is important to minimise the delay in first detection of CBSD after introduction to a new country or state so that interventions can be deployed more effectively. Using a computational model that combines simulations of CBSD spread at both the landscape and field scales, we model the effectiveness of different country level survey strategies in Nigeria when CBSD is directly introduced.

Changes in cerebral vascular reactivity following mild repetitive head injury in awake rats: modeling the human experience.

The changes in brain function in response to mild head injury are usually subtle and go undetected. Physiological biomarkers would aid in the early diagnosis of mild head injury. In this study we used hypercapnia to follow changes in cerebral vascular reactivity after repetitive mild head injury.

Vision Is Not Required to Elicit Balance Improvements From Beam Walking Practice.

Background: Beam walking is a highly studied assessment of walking balance. Recent research has demonstrated that brief intermittent visual rotations and occlusions can increase the efficacy of beam walking practice on subsequent beam walking without visual perturbations. We sought to examine the influence of full vision removal during practice walking on a treadmill-mounted balance beam.

Pencil Beam Scanning Proton Therapy as Single Vocal Cord Irradiation for Early-Stage Glottic Cancer.

Purpose: Single vocal cord irradiation (SVCI) is a promising technique to maintain excellent oncologic control and potentially improve upon toxicities for treatment of early-stage glottic squamous cell carcinomas. We sought to investigate whether pencil beam scanning (PBS) proton therapy could improve upon the already favorable dose gradients demonstrated with volumetric modulated arc therapy (VMAT) SVCI.

Patients And Methods: A 64-year-old gentleman was treated in our department with 6X-flattening filter-free VMAT SVCI to 58.

Adult perceptions of mental health access barriers facing youth in rural Washington State: A group concept mapping study.

Purpose: To explore adult community members' perspectives concerning barriers to mental health care that confront rural-dwelling youth.

Methods: Group concept mapping, a participatory community-engaged research method, was used. Adult community members brainstormed and sorted statements describing barriers rural youth encounter in accessing mental health services.

Walking Ankle Biomechanics of Individuals With Transtibial Amputations Using a Prescribed Prosthesis and a Portable Bionic Prosthesis Under Myoelectric Control.

Individuals with transtibial amputation can activate residual limb muscles to volitionally control robotic ankle prostheses for walking and postural control. Most continuous myoelectric ankle prostheses have used a tethered, pneumatic device. The Open Source Leg allows for myoelectric control on an untethered electromechanically actuated ankle.

Method Matters: Integrating Trauma-Informed Principles into Psychiatric and Mental Health Nursing Research.

Psychiatric and mental health (PMH) nurses integrate the concept of trauma-informed care into practice, policy, and education. Despite the frequency of PMH nurses practicing in a trauma-informed manner, there is a paucity of literature focused on integrating trauma-informed principles into research methods. Professions outside of the nursing sphere, specifically social work and social sciences, predominate the discourse around trauma-informed research.

Comparison of Machine Learning Approaches for Prediction of the Equivalent Alkane Carbon Number for Microemulsions Based on Molecular Properties.

The chemical properties of oils are vital in the design of microemulsion systems. The hydrophilic-lipophilic difference equation used to predict microemulsions' phase behavior expresses the oils' physiochemical properties as the equivalent alkane carbon number (EACN). The experimental determination of EACN requires knowledge of the temperature dependence of the microemulsion system and the effects of different surfactant concentrations.

Association between multimorbidity and postoperative mortality in patients undergoing major surgery: a prospective study in 29 countries across Europe.

Background: Multimorbidity poses a global challenge to healthcare delivery. This study aimed to describe the prevalence of multimorbidity, common disease combinations and outcomes in a contemporary cohort of patients undergoing major abdominal surgery.

Methods: This was a pre-planned analysis of a prospective, multicentre, international study investigating cardiovascular complications after major abdominal surgery conducted in 446 hospitals in 29 countries across Europe.

Single-molecule epiallelic profiling of DNA derived from routinely collected Pap specimens for noninvasive detection of ovarian cancer.

Recent advances in molecular analyses of ovarian cancer have revealed a wealth of promising tumour-specific biomarkers, including protein, DNA mutations and methylation; however, reliably detecting such alterations at satisfactorily high sensitivity and specificity through low-cost methods remains challenging, especially in early-stage diseases. Here we present PapDREAM, a new approach that enables detection of rare, ovarian-cancer-specific aberrations of DNA methylation from routinely-collected cervical Pap specimens. The PapDREAM approach employs a microfluidic platform that performs highly parallelized digital high-resolution melt to analyze locus-specific DNA methylation patterns on a molecule-by-molecule basis at or near single CpG-site resolution at a fraction (< 1/10th) of the cost of next-generation sequencing techniques.

Internal Medicine Acting Internship Trends in Rotation Structure and Student Responsibilities: Results from a 2023 National Survey.

Background: The acting internship (AI) in internal medicine plays a key role in the transition from medical school to residency. While there have been recent changes in medical education including a pass/fail USMLE Step 1 and increasing use of competency-based assessment, there has not been a large survey of the state of the AI in many years.

Objective: To assess the current landscape of the internal medicine AI and identify areas in need of standardization.

Resident memory T cells in dirty mice suppress innate cell activation and infiltration into the skin following stimulation with alarmins.

Trm cells are sequestered at barrier tissues as a swift first line defense against peripheral reinfections in both antigen dependent and antigen independent bystander modes. Trm cells are also capable of mediating autoimmune diseases, such as psoriasis, wherein autoreactive Trm cells are aberrantly activated. To quickly combat infections, activated Trm cells can stimulate the influx and activation of memory T cells and innate immune cells.
