Published: July 2017

Family history is an important component in modern clinical care especially in the era of precision medicine. Family history information in the Electronic Health Record (EHR) system is usually stored in structured format as well as in free-text format. In this study, we systematically analyzed a family history text corpus from 3 million clinical notes for the patients receiving their primary care at Mayo Clinic. Family members, medical problems, and their associations were analyzed and reported. Our findings showed a great agreement between positive/negated medical problems mentioned in the diagnosis report and the family history, as measured by observed agreement and random agreement. We also found that the family history of some medical problems existed up to 10~15 years prior to the diagnosis date of such problems. Finally two patient cases were studied to show the medical problems in the diagnosis and family history associated with the timeline.

Introduction: , a genus within the Zingiberales order, is renowned for its diverse morphology, suggesting a rich genetic reservoir. However, genetic research on plants within the family has primarily focused on taxonomy and phylogenetics, with limited exploration into other genetic aspects, particularly the chloroplast genome. Given the significance of chloroplast genomes in evolutionary studies, a deeper understanding of their structure and diversity within Heliconia is essential.

Backgrounds: Breech presentation, family history, and physical examination are the most recognized risk factors for DDH, which form the basis of selective screening. However, this approach can lead to late diagnosis, invasive treatments, and complications. This study analyzes the effectiveness of selective screening and identifies additional factors related to DDH.

Purpose: To assess the efficacy of clinical exome sequencing (CES) in individuals involved in assisted reproductive technology (ART) or sperm donor programs, with a specific focus on its impact on clinical decision-making.

Methods: A total of 3991 individuals without a family history of genetic disorders underwent CES targeting 5595 genes at a reproductive center between December 2022 and April 2024. The cohort comprised 217 sperm donors, 232 female recipients, and 1771 couples (3542 patients) undergoing ART with their own gametes.
