Article Abstract
Women with pathogenic germline mutations in and genes have an increased risk to develop breast and ovarian cancer. There is, however, a high interpersonal variability in the modality and timing of tumor onset in those subjects, thus suggesting a potential role of other individual's genetic, epigenetic, and environmental risk factors in modulating the penetrance of BRCA mutations. MicroRNAs (miRNAs) are small noncoding RNAs that can modulate the expression of several genes involved in cancer initiation and progression. MiRNAs are dysregulated at all stages of breast cancer and although they are accessible and evaluable, a standardized method for miRNA assessment is needed to ensure comparable data analysis and accuracy of results. The aim of this review was to highlight the role of miRNAs as potential biological markers for BRCA mutation carriers. In particular, biological and clinical implications of a link between lifestyle and nutritional modifiable factors, miRNA expression and germline and mutations are discussed with the knowledge of the best available scientific evidence.

ift140-Deficient Zebrafish as a Model for Kidney Cystogenesis and an F0-Based Screen for Genetic Modifiers of Kidney Cysts.
J Am Soc Nephrol
September 2025
Department of Biochemistry and Molecular Biology, Mayo Clinic, Rochester, MN, USA.
Background: Genetic modifiers are believed to play an important role in the onset and severity of polycystic kidney disease (PKD), but identifying these modifiers has been challenging due to the lack of effective methodologies.
Methods: We generated zebrafish mutants of IFT140, a skeletal ciliopathy gene and newly identified autosomal dominant PKD (ADPKD) gene, to examine skeletal development and kidney cyst formation in larval and juvenile mutants. Additionally, we utilized ift140 crispants, generated through efficient microhomology-mediated end joining (MMEJ)-based genome editing, to compare phenotypes with mutants and conduct a pilot genetic modifier screen.
Histologic Chorioamnionitis and Neurodevelopment in Preterm Infants.
JAMA Netw Open
September 2025
Perinatal Institute, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio.
Importance: Exposure to inflammation from chorioamnionitis places the fetus at higher risk of premature birth and may increase the risk of neurodevelopmental impairments, though the evidence for the latter is mixed.
Objective: To evaluate whether moderate to severe histologic chorioamnionitis (HCA) is directly associated with adverse motor performance, independent of the indirect mediating effects of premature birth.
Design, Setting, And Participants: This prospective, population-based cohort study recruited participants between September 16, 2016, and November 19, 2019, from referral and nonreferral neonatal intensive care units of 5 southwestern Ohio hospitals.
Cardiovascular Risk Prediction in Older Adults.
Curr Atheroscler Rep
September 2025
Department of Medicine, Division of Cardiovascular Disease, University of Alabama at Birmingham, 521 19th Street South-GSB 444, Birmingham, AL, 35233, USA.
Purpose Of Review: This review examines cardiovascular disease (CVD) risk prediction models relevant to older adults, a rapidly expanding population with elevated CVD risk. It discusses model characteristics, performance metrics, and clinical implications.
Recent Findings: Some models have been developed specifically for older adults, while several others consider a broader age range, including some older individuals.
An observational study on mesangial C4d staining as a prognostic tool in IgA nephropathy.
J Nephrol
September 2025
Institute of Nephrology, Madras Medical College, Chennai, India.
Background: IgA nephropathy is a disease with a highly variable natural history, for which there is an increasing understanding of the role of complement activation in its pathogenesis and progression. We aimed to assess the clinical and prognostic implications of C4d staining in the kidney biopsy of IgA nephropathy patients.
Methods: This was a retrospective observational study wherein the medical records of IgA nephropathy patients were reviewed and baseline characteristics, kidney biopsy findings, treatment response and follow-up data were noted.

Randomized pretest, posttest, follow-up (RPPF) designs are widely used in longitudinal behavioral intervention research to evaluate the efficacy of treatments over time. These designs typically involve random assignment of participants to treatment and control conditions, with assessments conducted at baseline, immediately post-intervention, and during the follow-up period. Researchers primarily focus on determining whether the intervention is more effective than the control condition at post-treatment and whether these effects are sustained or change over time.
