Brown-Séquard syndrome after blunt cervical spine trauma in a patient with preinjury multilevel hemilaminectomies and OPLL: illustrative case.

Background: Brown-Séquard syndrome (BSS) is a rare neurological condition characterized by injury to one-half of the spinal cord. In the context of trauma, BSS is typically seen with penetrating injuries. Here, the authors present the unique case of a patient presenting with BSS after blunt trauma.

Racial and Ethnic Disparities in Epidural Blood Patch Utilization Among Obstetric Patients in the United States: A Nationwide Analysis, 2016-2020.

Background: Racial and ethnic disparities in health care delivery can lead to inadequate peripartum pain management and associated adverse maternal outcomes. An epidural blood patch (EBP) is the definitive treatment for moderate to severe postdural puncture headache (PDPH), a potentially debilitating neuraxial anesthesia complication associated with significant maternal morbidity if undertreated. In this nationwide study, we examine the racial and ethnic disparities in the inpatient utilization of EBP after obstetric PDPH in the United States.

An exploration of anxiety and depressive symptoms among sexual and gender minority young adults visiting a drop-in center for youth experiencing homelessness.

Background: Research suggests that marginalized young adults, particularly sexual and gender minorities (SGM), face distinctive healthcare transition challenges. SGM often navigate a complex intersection of identities, experiences, and stressors that can contribute to mental health disparities. However, they often lack access to appropriate support and resources tailored to their needs, which can result in increased psychological distress.

Blocking feedback immunosuppression of antigen presentation in brain tumor during oncolytic virotherapy with oHSV-mshPKR.

Glioblastoma (GBM) is the most frequent malignant brain tumor. We recently discovered that oncolytic herpes simplex virus engineered to disable tumor-intrinsic protein kinase R (PKR) signaling (oHSV-shPKR) could increase oHSV oncolysis and anti-tumor immune response. However, here we show that disabling tumor-intrinsic PKR signaling can also induce the activation of the indoleamine 2,3-dioxygenase (IDO) signaling pathway.

Artificial Intelligence Assessment of Chest Radiographs for COVID-19.

Background: The sensitivity of reverse-transcription polymerase chain reaction (RT-PCR) is limited for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Chest computed tomography (CT) is reported to have high sensitivity; however, given the limited availability of chest CT during a pandemic, the assessment of more readily available imaging, such as chest radiographs, augmented by artificial intelligence may substitute for the detection of the features of coronavirus disease 2019 (COVID-19) pneumonia.

Methods: We trained a deep convolutional neural network to detect SARS-CoV-2 pneumonia using publicly available chest radiography imaging data including 8,851 normal, 6,045 pneumonia, and 200 COVID-19 pneumonia radiographs.

Purpose: To create a nomogram for accurate prognosis of patients with clear cell renal cell carcinoma (ccRCC) based on computed tomography images.

Methods: Eight hundred twenty-two ccRCC patients with contrast-enhanced computed tomography images involved in this study were collected. A rectangular region of interest surrounding the tumor was used to extract quantitative radiomics and deep-learning features, which were filtered by Cox proportional hazard regression model and least absolute shrinkage and selection operator.

Effectiveness of Ventilation via an Endotracheal Tube in Pharynx Versus a Facemask in Patients With Potentially Difficult Airway: A Randomized, Crossover, and Blind Trial.

Background: The difficult airway is frequently encountered across many scenarios. The extreme form is a "cannot intubate and cannot oxygenate" scenario, which lacks a reliable rescue technique. Previous case reports or studies with small sample sizes indicate the feasibility and efficiency of an endotracheal tube in the pharynx (TTIP) to ventilate patients.

Recovery Residences Are an Innovative Site for HIV Prevention Interventions Targeting People Who Inject Drugs: Preliminary Data From Project HOMES.

Of 1.2 million Americans who would benefit from pre-exposure prophylaxis (PrEP), only 36% were prescribed PrEP in 2023. Project HOMES is an ongoing study that evaluates recovery residences for individuals in medication-assisted recovery from opioid use disorder across five Texas cities.

Designing a blockchain technology platform for enhancing the pre-exposure prophylaxis care continuum.

Objectives: Pre-exposure prophylaxis (PrEP) is a key biomedical intervention for ending the HIV epidemic in the United States, but its uptake is impeded by systemic barriers, including fragmented workflows and ineffective data coordination. This study aims to design PrEPLinker, a blockchain-based, client-centered platform to enhance care to address these challenges by improving care coordination and enabling clients to securely manage their identity and PrEP-related data.

Materials And Methods: Using Houston, Texas, as a use case, we conducted a needs assessment with PrEP collaborators to evaluate existing workflows and identify barriers in the PrEP care continuum.

Effects of vagus nerve stimulation on daily function and quality of life in markedly treatment-resistant major depression: Findings from a one-year, randomized, sham-controlled trial.

Background: Depression treatments aim to minimize symptom burden and optimize quality of life (QoL) and psychosocial function.

Objective: Compare the effects of adjunctive versus sham vagus nerve stimulation (VNS) on QoL and function in markedly treatment-resistant depression (TRD).

Methods: In this multicenter, double-blind, sham-controlled trial, 493 adults with TRD and ≥4 adequate but unsuccessful antidepressant treatment trials (current episode) were randomized to active (n = 249) or sham (n = 244) VNS (plus treatment as usual) over a 12-month observation period.

Association of same-day antiplatelet loading and outcomes after transcarotid artery revascularization.

Objective: Prior studies have emphasized the importance of compliance with preoperative dual antiplatelet therapy (DAPT) in patients undergoing transcarotid artery revascularization (TCAR). This investigation examines differences in perioperative outcomes after TCAR in those receiving a loading dose of antiplatelet medications on the day of the procedure vs those already maintained on DAPT.

Methods: Consecutive TCAR procedures from the Vascular Quality Initiative (2016-2022) were identified.

Untargeted metabolome atlas for sleep-related phenotypes in the Hispanic community health study/study of Latinos.

Background: Sleep is essential to maintaining health and wellbeing of individuals, influencing a variety of outcomes from mental health to cardiometabolic disease. This study aims to assess the relationships between various sleep-related phenotypes and blood metabolites.

Methods: Utilising data from the Hispanic Community Health Study/Study of Latinos, we performed association analyses between 40 sleep-related phenotypes, grouped in several domains (sleep disordered breathing (SDB), sleep duration, sleep timing, self-reported insomnia symptoms, excessive daytime sleepiness (EDS), and heart rate during sleep), and 768 metabolites measured via untargeted metabolomics profiling.

Antibody-Drug Conjugates Targeting the EGFR Ligand Epiregulin Elicit Robust Anti-Tumor Activity in Colorectal Cancer.

As colorectal cancer (CRC) remains a leading cause of cancer-related death, identifying therapeutic targets and approaches is essential to improve patient outcomes. The EGFR ligand epiregulin (EREG) is highly expressed in RAS wildtype and mutant CRC with minimal expression in normal tissues, making it an attractive target for antibody-drug conjugate (ADC) development. In this study, we produced and purified an EREG monoclonal antibody (mAb), H231, that had high specificity and affinity for human and mouse EREG.

Inherited Retinal Degenerations and Non-Neovascular Age-Related Macular Degeneration: Progress and Unmet Needs.

Systemic Administration of a Site-Targeted Complement Inhibitor Attenuates Chronic Stress-Induced Social Behavior Deficits and Neuroinflammation in Mice.

Chronic stress, a risk factor for many neuropsychiatric conditions, causes dysregulation in the immune system in both humans and animal models. Additionally, inflammation and synapse loss have been associated with deficits in social behavior. The complement system, a key player of innate immunity, has been linked to social behavior impairments caused by chronic stress.

Efficient multi-phenotype genome-wide analysis identifies genetic associations for unsupervised deep-learning-derived high-dimensional brain imaging phenotypes.

Brain imaging is a high-content modality that offers dense insights into the structure and pathology of the brain. Existing genetic association studies of brain imaging, typically focusing on a number of individual image-derived phenotypes (IDPs), have successfully identified many genetic loci. Previously, we have created a 128-dimensional Unsupervised Deep learning derived Imaging Phenotypes (UDIPs), and identified multiple loci from single-phenotype genome-wide association studies (GWAS) for individual UDIP dimensions, using data from the UK Biobank (UKB).
