Using Unannounced Standardized Patients to Assess Clinician Telehealth and Communication Skills at an Urban Student Health Center.

Purpose: As the COVID-19 pandemic forced most colleges and universities to go online, student health centers rapidly shifted to telehealth platforms without frameworks for virtual care provision. An urban student health center implemented a needs assessment involving unannounced standardized patients (USPs) to evaluate the integration of a new telehealth workflow and clinicians' virtual communication skills.

Methods: From April to May 2021, USPs conducted two video visits with 12 primary care and four women's health clinicians (N = 16 clinicians; 32 visits).

Pivotal studies of orphan drugs approved for neurological diseases.

Objective: To identify design elements of clinical trials leading to US Food and Drug Administration approval of drugs for neurological diseases with and without orphan indications.

Methods: We used publicly available information to identify approvals for drugs for neurological diseases with an orphan indication (n = 19) and compared them with recent approvals for drugs for neurological diseases without an orphan indication (n = 20). We identified "pivotal trials" from drug labels and drug approval packages, and assessed them on four elements of clinical trial design: control, blinding, randomization, and size.

Mus81-Eme1-dependent and -independent crossovers form in mitotic cells during double-strand break repair in Schizosaccharomyces pombe.

During meiosis, double-strand breaks (DSBs) lead to crossovers, thought to arise from the resolution of double Holliday junctions (HJs) by an HJ resolvase. In Schizosaccharomyces pombe, meiotic crossovers are produced primarily through a mechanism requiring the Mus81-Eme1 endonuclease complex. Less is known about the processes that produces crossovers during the repair of DSBs in mitotic cells.

Rqh1 blocks recombination between sister chromatids during double strand break repair, independent of its helicase activity.

Many questions remain about the process of DNA double strand break (DSB) repair by homologous recombination (HR), particularly concerning the exact function played by individual proteins and the details of specific steps in this process. Some recent studies have shown that RecQ DNA helicases have a function in HR. We studied the role of the RecQ helicase Rqh1 with HR proteins in the repair of a DSB created at a unique site within the Schizosaccharomyces pombe genome.
