Post-transcriptional regulation of IFI16 promotes inflammatory endothelial pathophenotypes observed in pulmonary arterial hypertension.

Am J Physiol Lung Cell Mol Physiol

January 2025

Center for Pulmonary Vascular Biology and Medicine, Pittsburgh Heart, Lung, and Blood Vascular Medicine Institute, Division of Cardiology, Department of Medicine, University of Pittsburgh School of Medicine and University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, United States.

Article Synopsis
  • Pulmonary arterial hypertension (PAH) is a disease caused by inflammation and dysfunction in blood vessel cells, leading to changes in the lungs' blood vessels.
  • The study highlights the role of the protein IFI16 in promoting inflammation in these endothelial cells, especially when triggered by the inflammatory molecule IL-1b.
  • Additionally, the research suggests that changes in m6A modification of IFI16 may serve as a potential biomarker for identifying PAH in patients, as increased m6A levels were found in their blood cells compared to healthy controls.

The dynamic susceptibility contrast (DSC) MRI measures of relative cerebral blood volume (rCBV) play a central role in monitoring therapeutic response and disease progression in patients with gliomas. Previous investigations have demonstrated promise of using rCBV in classifying tumor grade, elucidating tumor viability after therapy, and differentiating pseudoprogression and pseudoresponse. However, the quantification and reproducibility of rCBV measurements across patients, devices, and software remain a critical barrier to routine or clinical trial use of longitudinal DSC MRI in patients with gliomas.

Purpose: Breast density is a widely established independent breast cancer risk factor. With the increasing utilization of digital breast tomosynthesis (DBT) in breast cancer screening, there is an opportunity to estimate volumetric breast density (VBD) routinely. However, current available methods extrapolate VBD from two-dimensional (2D) images acquired using DBT and/or depend on the existence of raw DBT data, which is rarely archived by clinical centers because of storage constraints.

Despite being a common urologic disorder with potentially complicated sequela, the genetic background of adult hydrocele has not previously been described. We performed a multi-population genome-wide association study of 363,460 men in the United Kingdom BioBank and FinnGen cohorts. We identified 6,548 adult men with hydrocele.

Neurodevelopmental disorders are thought to arise from intrinsic brain abnormalities. Alternatively, they may arise from disrupted crosstalk among tissues. Here we show the local reduction of two vestibulo-cerebellar lobules, the paraflocculus and flocculus, in mouse models and humans with 22q11.

Poly(adenosine diphosphate-ribose) polymerase-1 (PARP1) inhibitors have improved ovarian cancer treatment outcomes. However, clinical response remains heterogeneous. Existing biomarkers, mainly breast cancer susceptibility genes 1 and 2 (), are suboptimal.

Article Synopsis
  • There is growing interest in using point of care ultrasound (POCUS) as a teaching tool in medical courses, particularly for cardiac anatomy and physiology; however, few studies have explored team-based learning (TBL) approaches for this topic.
  • This study introduced a novel TBL exercise called Team-Based Learning - Ultrasound (TBL-US) for first-year medical students, comprising phases such as preparation, team readiness, image acquisition, and knowledge assessment, facilitated by trained second-year students.
  • Results showed significant improvements in students’ knowledge of cardiac POCUS and cardiovascular content, with enhanced final exam scores for TBL-US participants compared to non-participants, indicating that this method effectively supports learning in preclinical medical education.

Low Penetrance Sarcomere Variants Contribute to Additive Risk in Hypertrophic Cardiomyopathy.

Circulation

December 2024

Department of Internal Medicine, Division of Cardiovascular Medicine, University of Michigan, Ann Arbor. (E.D.S., Y.-C.T., B.E., A.B., O.M., S.S., A.S.H.).

Article Synopsis
  • - Hypertrophic cardiomyopathy (HCM) was traditionally seen as caused by rare, high-risk single-gene changes, but new research indicates common low-risk variants (LowSVs) also play a significant role in the disease.
  • - In a study of over 6000 patients, 12 LowSVs were discovered, which are relatively common in the general population and more prevalent in HCM patients, suggesting they may influence disease severity and risk.
  • - While LowSVs alone are linked to a later onset of HCM and fewer complications, their presence alongside more severe genetic variants increases health risks significantly.

Purpose: Psychological distress, including anxiety and depression, is common among adults with CF, associating with poor quality of life, lung function, and healthcare utilization. This 3-year, multi-site, telehealth-delivered randomized trial sought to determine whether Acceptance and Commitment Therapy (ACT with CF) is superior to supportive psychotherapy (SP), in improving psychological functioning for adults with CF.

Methods: One hundred twenty-four adults with CF and elevated anxiety and/or depressive symptoms were recruited coincident with the first COVID lockdown, from Thomas Jefferson University Hospitals, University of Virginia, Augusta University, Duke University Medical Center, and social media.

With immuno-oncology becoming the standard of care for a variety of cancers, identifying biomarkers that reliably classify patient response, resistance, or toxicity becomes the next critical barrier towards improving care. Multi-parametric, multi-omics, and computational platforms generating an unprecedented depth of data are poised to usher in the discovery of increasingly robust biomarkers for enhanced patient selection and personalized treatment approaches. Deciding which developing technologies to implement in clinical settings ultimately, applied either alone or in combination, relies on weighing pros and cons, from minimizing patient sampling to maximizing data outputs, and assessing reproducibility and representativeness of findings, while lessening data fragmentation towards harmonization.

Introduction: Heart transplantation, the gold standard for end-stage cardiomyopathy, is hindered by donor shortages and clinical deterioration. Left ventricular assist devices (LVADs) have emerged as crucial alternatives, stabilizing hemodynamics, reversing end-organ damage, and enabling patient discharge. Significant engineering advancements and iterative improvements have since produced devices capable of rivaling heart transplantation in early survival potential.

November 2024

Graduate Group in Applied Mathematics and Computational Science, University of Pennsylvania, Philadelphia, PA 19104, USA.

Human organ structure and function are important endophenotypes for clinical outcomes. Genome-wide association studies (GWAS) have identified numerous common variants associated with phenotypes derived from magnetic resonance imaging (MRI) of the brain and body. However, the role of rare protein-coding variations affecting organ size and function is largely unknown.

Transpl Infect Dis

November 2024

Division of Infectious Diseases, Department of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Background: Despite limited data supporting use in solid organ transplant (SOT) recipients, atovaquone and dapsone are often used as alternatives to trimethoprim-sulfamethoxazole (TMP-SMX) for Pneumocystis jirovecii pneumonia (PJP) prophylaxis.

Methods: This single-center, retrospective cohort study describes a multi-organ program's experience with alternative PJP prophylaxis. Adult SOT recipients transplanted November 13, 2020 to November 13, 2022 who received non-TMP-SMX PJP prophylaxis and had > 1 year follow-up were included.

Electronic address:

Clinical trials evaluating chimeric antigen receptor T-cell therapy (CAR T) commonly report time-to-event (TTE) endpoints. However, definitions are not necessarily comparable across studies and variability can lead to misinterpretation of results or inappropriate comparisons across products and studies. Amid the rapidly increasing number of published CAR T trials-many of which were used for regulatory approval-this study aims to summarize the variation in the use and reporting of TTE endpoints in CAR T trials.

Background: The first long-acting injectable antiretroviral, cabotegravir/rilpivirine (LA-CAB/RPV), was FDA approved in January 2021 for persons with HIV suppressed on their current regimen. Body mass index (BMI) ≥30 kg/m2 has been identified as a risk factor for virologic failure, however data is limited due to small sample sizes. The aim of this study was to evaluate the impact of BMI on the efficacy of LA-CAB/RPV in a real-world setting.
