Objective: In order to enable clinicians to refer the right persons suspected of familial hypercholesterolemia (FH) for mutation screening, a retrospective study was conducted in a Danish FH cohort.
Design And Methods: The study comprised 643 probands and 395 relatives, of which 421 individuals had a pathogenic mutation, and 211 had cardiovascular disease (CVD). Logistic regression, Cox regression, and receiver operating characteristics (ROC) curves were used to find optimal predictive variables for mutation status and evaluate risk factors for CVD.
Results: Age alone had significant predictive power in both genders. ROC curves and area under the curve plots found no parameters capable of predicting mutation status. The only significant risk factor for CVD in both genders was mutation carrier status.
Conclusions: No parameters could decipher mutation status a priori. All individuals fulfilling the FH criteria should therefore be referred in order to facilitate family tracing and genetic counseling.

The growth and survival of cells with different fitness, such as those with a proliferative advantage or a deleterious mutation, is controlled through cell competition. During development, cell competition enables healthy cells to eliminate less fit cells that could jeopardize tissue integrity, and facilitates the elimination of pre-malignant cells by healthy cells as a surveillance mechanism to prevent oncogenesis. Malignant cells also benefit from cell competition to promote their expansion.

Background: The reported benefit of poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance in patients with newly diagnosed and platinum (Pt)-sensitive recurrent ovarian cancer (OC) included in randomized clinical trials needs to be corroborated in a less selected population.
Objective: The aim is to increase the evidence on niraparib in a real-world setting.
Methods: This is a retrospective observational study including women with platinum-sensitive relapsed high-grade serous OC who started niraparib maintenance between August 2019 (marketing data, Spain) and May 2022.

Results following hematopoietic stem cell transplantation (HSCT) for TP53-mutated myeloid malignancies are disappointing. Several HSCT centers decline to perform HSCT for patients with TP53 mutation because of poor outcomes. In this study, we analyzed 240 patients with TP53-mutated myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) that underwent HSCT.

-methyladenosine (mA) in eukaryotic RNA is an epigenetic modification that is critical for RNA metabolism, gene expression regulation, and the development of organisms. Aberrant expression of mA components appears in a variety of human diseases. RNA mA modification in has proven to be involved in sex determination regulated by and may affect X chromosome expression through the MSL complex.
