This case highlights a stepwise approach in the anatomical characterization of sinus of Valsalva aneurysm using multimodality imaging and the use of hemodynamic assessment and intraoperative imaging to guide surgical planning.Evaluation of multiple community-based approaches to improve Latinas' breast cancer (BC) screening utilization has resulted in inconsistent findings. Factors contributing to this variation include heterogeneity in approaches (e.g., types of conceptual frameworks) and study quality (e.g., lack of measurement of spillover effects). find more This pilot study sought to clarify which approach may be most effective by evaluating the relative efficacy of two conceptual approaches using an area-level design with 145 Latinas nonadherent to U.S. Preventive Services Taskforce (USPSTF) BC screening guidelines. Each study arm included identical intervention format and duration (e.g., three group-based sessions, logistic assistance (LA) via five monthly calls and referral to free/low-cost screening programs). However, study content differed. While educate+LA addressed participants' BC prevention and screening behavior, empower+LA addressed participants' and their social networks' BC screening. After adjusting for age, insurance status, and baseline mammography intention, when compared with educate+LA participants, empower+LA participants were more likely to report obtaining mammograms, engaging more individuals about BC, initiating BC conversations in public settings, and discussing mammography specifically. Our study has important implications regarding the utility of evaluating behavioral interventions overall in terms of behavioral and spillover network effects.This article is about the feelings - affect - induced by the digital rectal exam of the prostate and the gynaecological bimanual pelvic exam, and the care doctors are or are not instructed to give. The exams are both invasive, intimate exams located at a part of the body often charged with norms and emotions related to gender and sexuality. By using the concept affective subject, we analyse how these examinations are taught to medical students, bringing attention to how bodies and affect are cared for as patients are observed and touched. Our findings show both the role care practices play in generating and handling affect in the students' learning and the importance of the affect that the exam is (or is not) imagined to produce in the patient. Ours is a material-discursive analysis that includes the material affordances of the patient and doctor bodies in the affective work spaces observed.Functional Somatic Symptoms (FSS) are physical symptoms that cannot be attributed to underlying pathology. Their severity is often measured with sum scores on questionnaires; however, this may not adequately reflect FSS severity in subgroups of patients. We aimed to identify the items of the somatization section of the Composite International Diagnostic Interview that best discriminate FSS severity levels, and to assess their functioning in sex and age subgroups. We applied the two-parameter logistic model to 19 items in a population-representative cohort of 962 participants. Subsequently, we examined differential item functioning (DIF). "Localized (muscle) weakness" was the most discriminative item of FSS severity. "Abdominal pain" consistently showed DIF by sex, with males reporting it at higher FSS severity. There was no consistent DIF by age, however, "Joint pain" showed poor discrimination of FSS severity in older adults. These findings could be helpful for the development of better assessment instruments for FSS, which can improve both future research and clinical care.Purpose in life is associated with greater engagement in physical activity. The present research (N = 3473) addresses whether motivations and barriers to physical activity mediate this relation concurrently and prospectively early in the coronavirus pandemic. Higher purpose was associated with greater intrinsic, identified, and external motivation for physical activity and fewer barriers. Intrinsic motivation was a robust mediator of the relation between purpose and more physical activity and less sedentary behavior reported concurrently and prospectively; identified motivation mediated the relation with physical activity. Purpose in life is associated with being more physically active through both greater enjoyment and valuing its benefits.Targeted protein degradation is an emerging new strategy for the modulation of intracellular protein levels with applications in chemical biology and drug discovery. One approach to enable this strategy is to redirect the ubiquitin-proteasome system to mark and degrade target proteins of interest (POIs) through the use of proteolysis targeting chimeras (PROTACs). Although great progress has been made in enabling PROTACs as a platform, there are still a limited number of E3 ligases that have been employed for PROTAC design. Herein we report a novel phenotypic screening approach for the identification of E3 ligase binders. The key concept underlying this approach is the high-throughput modification of screening compounds with a chloroalkane moiety to generate HaloPROTACs in situ, which were then evaluated for their ability to degrade a GFP-HaloTag fusion protein in a cellular context. As proof of concept, we demonstrated that we could generate and detect functional HaloPROTACs in situ, using a validated Von Hippel-Lindau (VHL) binder that successfully degraded the GFP-HaloTag fusion protein in living cells. We then used this method to prepare and screen a library of approximately 2000 prospective E3 ligase-recruiting molecules.
Participants are integral to the success of any clinical research study, yet participant recruitment into clinical trials poses ongoing and complex challenges. It is widely accepted and recognised that clinical trial sites often find it difficult to meet recruitment goals, both in terms of accrual targets and timelines. This can impact the validity of trials or cause major delays for research. There are very few frameworks available to clinical trial sites to improve recruitment. The GREET project (Guidance to Recruitment Examining Experiences at clinical Trial sites) sought to identify barriers to recruitment and produce formal guidance to optimise recruitment outcomes.

Clinical Trials Impact and Quality, a collaborative of sector stakeholders, convened a project team with comprehensive knowledge of the Australian clinical trials sector to undertake the GREET project. The project scope included exploration of recruitment issues at a site level across all phases of clinical trials and all types of trial sites.
