A Clinical Trial to Increase the Identification, Genetic Counseling Referral and Genetic Testing of Women at risk for Hereditary Breast and/or Ovarian Cancer
Background: Approximately 1/300 individuals in the general population are at risk for hereditary breast and ovarian cancer due to an inherited mutation in the BRCA1/BRCA2 genes. BRCA mutations are associated with dramatically increased risks for breast cancer, especially at younger ages, in addition to ovarian cancer. Enhanced screening and risk reduction strategies can significantly reduce associated morbidity and mortality. The United States Preventive Services Task Force (USPSTF) recommends identifying women at-risk for BRCA mutations for receipt of genetic counseling and if appropriate, testing. The Breast Cancer Genetics Referral Screening Tool (B-RST) is a validated screen endorsed by USPSTF to facilitate this process. This implementation study seeks to evaluate the most effective means of follow-up for screen-positive women to maximize the number who are referred to, and receive, cancer genetic counseling (CGC) services.
Methods: B-RST (v3.0) was used in three Emory Healthcare breast-imaging centers. Screen-positive women were randomized into three methods of follow-up (patient initiated, physician notification, or staff phone call). Primary outcomes were to compare the number of screen positive individuals who were referred for, scheduled, and completed a CGC appointment among the three groups.
Results: Of 3,419 women approached, 63% participated and 579 (27%) screened positive. Appointments were scheduled by 7% of Group 1 participants, 17% of Group 2 individuals, and 11% of Group 3.
Conclusions: Genomic medicine is receiving increased attention in the public health arena. Screening with B-RST 3.0 in mammography settings can improve identification of individuals at-risk for BRCA mutations and facilitate referral to CGC services. Despite B-RST’s ability to easily and accurately identify individuals appropriate for CGC, additional strategies are needed to facilitate completion of CGC in routine clinical practice
Interhospital Transfers: Managing Competing Priorities while Ensuring Patient Safety
Interhospital patient transfers (IPTs) are highly complex logistical undertakings, involving a multitude of interdependent procedures, critical steps and a degree of unpredictability. Beginning with interfacility communication and patient acceptance agreement, a cascade of numerous handoffs takes place, ultimately culminating in safe arrival of the patient at the receiving facility. Due to the complexity of the IPT process, significant potential for critical errors and adverse patient safety (PS) outcomes exists. To minimize any associated risks, key PS considerations include checklists, handoffs, vehicle/aircraft safety, distance of travel, crew training, team factors, and many other critical components. Detailed knowledge of factors that may influence the risk of errors or adverse events is critical to optimizing both PS and clinical outcomes
Patient Self-Harm in the Emergency Department: An Evidence- Based Approach
Violence, deliberate self harm, and suicide in emergency departments and hospitals is likely to remain a significant problem for health care systems well into the future. Understanding how to confront, intervene, and manage episodes of patient deliberate self harm is extremely important, and can be life-saving. Here, through a clinical vignette, and a discussion of deliberate self harm we will highlight the importance of the direct observation of such patients, containment procedures (seclusion and physical restraints), and the use of pharmacological adjuncts. We hope that this concise, practically-oriented review will provide our readers with foundational understanding of the topic, including the most important theoretical and clinical considerations
Where next for the European bioeconomy?: The latest thinking from the European Bioeconomy Panel and the Standing Committee on Agricultural Research Strategic Working Group (SCAR)
System size and centrality dependence of the balance function in A+A collisions at sqrt[sNN]=17.2 GeV
Electric charge correlations were studied for p+p, C+C, Si+Si, and centrality selected Pb+Pb collisions at sqrt[sNN]=17.2 GeV with the NA49 large acceptance detector at the CERN SPS. In particular, long-range pseudorapidity correlations of oppositely charged particles were measured using the balance function method. The width of the balance function decreases with increasing system size and centrality of the reactions. This decrease could be related to an increasing delay of hadronization in central Pb+Pb collisions

Terminology for chain polymerization (IUPAC Recommendations 2021)
Chain polymerizations are defined as chain reactions where the propagation steps occur by reaction between monomer(s) and active site(s) on the polymer chains with regeneration of the active site(s) at each step. Many forms of chain polymerization can be distinguished according to the mechanism of the propagation step (e.g., cyclopolymerization – when rings are formed, condensative chain polymerization – when propagation is a condensation reaction, group-transfer polymerization, polyinsertion, ring-opening polymerization – when rings are opened), whether they involve a termination step or not (e.g., living polymerization – when termination is absent, reversible-deactivation polymerization), whether a transfer step is involved (e.g., degenerative-transfer polymerization), and the type of chain carrier or active site (e.g., radical, ion, electrophile, nucleophile, coordination complex). The objective of this document is to provide a language for describing chain polymerizations that is both readily understandable and self-consistent, and which covers recent developments in this rapidly evolving field
