Medical Imaging Data Strategies for Catalyzing AI Medical Device Innovation.

J Imaging Inform Med

January 2025

Office of Science and Engineering Laboratories, Center for Devices and Radiological Health, U.S. Food and Drug Administration, 10903 New Hampshire Ave, Silver Spring, MD, 20993, USA.

Continuous and consistent access to quality medical imaging data stimulates innovations in artificial intelligence (AI) technologies for patient care. Breakthrough innovations in data-driven AI technologies are founded on seamless communication between data providers, data managers, data users and regulators or other evaluators to determine the standards for quality data. However, the complexity in imaging data quality and heterogeneous nature of AI-enabled medical devices and their intended uses presents several challenges limiting the clinical translation of novel AI technologies.

Although DNA methyltransferase 1 (DNMT1) and RNA editor ADAR triplications exist in Down syndrome (DS), their specific roles remain unclear. DNMT methylates DNA, yielding S-adenosine homocysteine (SAH), subsequently converted to homocysteine (Hcy) and adenosine by S-adenosine homocysteine (Hcy) hydrolase (SAHH). ADAR converts adenosine to inosine and uric acid.

Triaging mammography with artificial intelligence: an implementation study.

Breast Cancer Res Treat

January 2025

Google Health, 1600 Amphitheatre Pkwy, Mountain View, CA, 94043, USA.

Purpose: Many breast centers are unable to provide immediate results at the time of screening mammography which results in delayed patient care. Implementing artificial intelligence (AI) could identify patients who may have breast cancer and accelerate the time to diagnostic imaging and biopsy diagnosis.

Methods: In this prospective randomized, unblinded, controlled implementation study we enrolled 1000 screening participants between March 2021 and May 2022.

Bridging Gaps: Enhancing Sleep and Health Disparities in Latino Families with Young Adults with Autism Using a Culturally Adapted Intervention.

J Racial Ethn Health Disparities

January 2025

Louis A. Faillace, MD, Department of Psychiatry and Behavioral Sciences, McGovern Medical School, UTHealth Science Center at Houston, UTHealth Houston Behavioral and Biomedical Sciences Building, 1941 East Rd, Houston, TX, 77054, USA.

The present study examined the effects of a culturally adapted intervention, ¡Iniciando! la Adultez, on sleep and health-related quality of life (HRQoL) in Latino young adults with autism spectrum disorder (ASD) and their Spanish-speaking parents. The intervention targeted the transition to adulthood, a period associated with increased challenges in sleep and HRQoL, particularly for underserved Latino populations. Participants included 26 young adults and 38 parents who completed assessments at baseline and post-treatment.

H, N, C backbone resonance assignment of human Alkbh7.

Biomol NMR Assign

January 2025

Department of Chemistry, Iowa State University, Hach Hall, 2438 Pammel Drive, Ames, IA, 50011, USA.

The Alkbh7 protein, a member of the Alkylation B (AlkB) family of dioxygenases, plays a crucial role in epigenetic regulation of cellular metabolism. This paper focuses on the NMR backbone resonance assignment of Alkbh7, a fundamental step in understanding its three-dimensional structure and dynamic behavior at the atomic level. Herein, we report the backbone H, N, C chemical shift assignment of the full-length human Alkbh7.

Sport participation affects body composition and bone health, but the association between sport, body composition, and bone health in female athletes is complex. We compared areal bone mineral density (aBMD, DXA) and tibial volumetric bone mineral density (vBMD), geometry, microarchitecture, and estimated strength (HR-pQCT) in cross-country runners (n = 22), gymnasts (n = 23) and lacrosse players (n = 35), and investigated associations of total body lean mass (TBLM), team, and their interaction with tibial bone outcomes. Total body (TB), total hip (TH), femoral neck (FN), and lumbar spine (LS) aBMD were higher in gymnasts than runners (p < 0.

Therapeutic efficacy and safety of adeno-associated virus (AAV) liver gene therapy depend on capsid choice. To predict AAV capsid performance under near-clinical conditions, we established side-by-side comparison at single-cell resolution in human livers maintained by normothermic machine perfusion. AAV-LK03 transduced hepatocytes much more efficiently and specifically than AAV5, AAV8 and AAV6, which are most commonly used clinically, and AAV-NP59, which is better at transducing human hepatocytes engrafted in immune-deficient mice.

Pre-exposure prophylaxis (PrEP), an effective biomedical prevention intervention, is not sufficiently reaching populations experiencing high HIV incidence. Behavioral health (BH) treatment addressing mental health and substance use similarly requires increased reach to HIV-affected populations. HIV testing is an opportunity to refer individuals to PrEP and BH treatment.

Prostate cancer treatment-related erectile dysfunction and stress urinary incontinence are commonly treated with inflatable penile prosthesis (IPP) or artificial urinary sphincter (AUS). Given the association with androgens and penile/urethral health, we aim to evaluate whether patients on androgen deprivation therapy (ADT) undergoing IPP or AUS surgery are at increased risk for reintervention, complication, or infection. We queried the TriNetX database for adult males receiving IPP or AUS.

Ongoing Symptoms and Concerns Experienced by Low-Risk Breast Cancer Survivors Following Active Treatment.

Ann Surg Oncol

January 2025

Department of Surgery, School of Medicine and Public Health, Wisconsin Surgical Outcomes Research Program, University of Wisconsin, Madison, WI, USA.

Introduction: Little is known about the symptom burden of breast cancer survivors with early-stage disease. Many studies have focused on symptoms of patients who are undergoing or recently completed systemic therapy. However, with the increased use of Oncotype DX, the proportion of early-stage hormone receptor-positive patients who undergo chemotherapy has declined, making existing studies of the symptom experience less useful for these patients.

Approximately 20% of paediatric and adolescent/young adult patients with renal tumours are diagnosed with non-Wilms tumour, a broad heterogeneous group of tumours that includes clear-cell sarcoma of the kidney, congenital mesoblastic nephroma, malignant rhabdoid tumour of the kidney, renal-cell carcinoma, renal medullary carcinoma and other rare histologies. The differential diagnosis of these tumours dates back many decades, when these pathologies were identified initially through clinicopathological observation of entities with outcomes that diverged from Wilms tumour, corroborated with immunohistochemistry and molecular cytogenetics and, subsequently, through next-generation sequencing. These advances enabled near-definitive recognition of different tumours and risk stratification of patients.
