Sensemaking and Group Relationships in Collaborative Exploratory Search

This study investigates the information seeking and sensemaking processes undertaken by groups engaged in collaborative exploratory searches. A second research question was what, if any, role the familiarity of the group members with each other had on how sensemaking occurred. Semi-structured interviews were conducted with eight participants, and each participant was asked to describe two collaborative search experiences, one with friends or family who they knew well, and one with an assigned group for school or work. Participants' experiences matched up well with existing information seeking models and current sensemaking models, but highlighted the importance of extensive use of artifacts and in-person communication as behaviors that facilitate sensemaking in a collaborative searching environment

The Effectiveness of Cervical Traction and Exercise in Decreasing Neck and Arm Pain for Patients With Cervical Radiculopathy: A Critically Appraised Topic

Clinical Question: Is there evidence to suggest intermittent cervical traction with cervical and scapular strengthening exercises is more effective in decreasing neck and arm pain when compared with cervical and scapular strengthening exercises alone in nonoperative patients with cervical radiculopathy? Clinical Bottom Line: There is currently inconsistent, high-quality evidence that suggests that the use of intermittent cervical traction in addition to strengthening exercises is more effective at decreasing pain in nonoperative patients with cervical radiculopathy when compared with strengthening alone. Future research should continue to examine long-term outcomes associated with cervical radiculopathy patients who use intermittent cervical traction as an intervention

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

Stromal Characteristics and Impact on New Therapies for Metastatic Triple-Negative Breast Cancer

The heterogenous nature of triple-negative breast cancer (TNBC) is an underlying factor in therapy resistance, metastasis, and overall poor patient outcome. The lack of hormone and growth factor receptors lends to the use of chemotherapy as the first-line treatment for TNBC. However, the failure of chemotherapy demonstrates the need to develop novel immunotherapies, antibody–drug conjugates (ADCs), and other tumor- and stromal-targeted therapeutics for TNBC patients. The potential for stromal-targeted therapy is driven by studies indicating that the interactions between tumor cells and the stromal extracellular matrix (ECM) activate mechanisms of therapy resistance. Here, we will review recent outcomes from clinical trials targeting metastatic TNBC with immunotherapies aimed at programed death ligand–receptor interactions, and ADCs specifically linked to trophoblast cell surface antigen 2 (Trop-2). We will discuss how biophysical and biochemical cues from the ECM regulate the pathophysiology of tumor and stromal cells toward a pro-tumor immune environment, therapy resistance, and poor TNBC patient outcome. Moreover, we will highlight how ECM-mediated resistance is motivating the development of new stromal-targeted therapeutics with potential to improve therapy for this disease

Impaired contraction and decreased detrusor innervation in a female rat model of pelvic neuropraxia

Introduction and hypothesis: Bilateral pelvic nerve injury (BPNI) is a model of post-radical hysterectomy neuropraxia, a common sequela. This study assessed the time course of changes to detrusor autonomic innervation, smooth muscle (SM) content and cholinergic-mediated contraction post-BPNI. Methods: Female Sprague–Dawley rats underwent BPNI or sham surgery and were evaluated 3, 7, 14, and 30 days post-BPNI (n = 8/group). Electrical field-stimulated (EFS) and carbachol-induced contractions were measured. Gene expression was assessed by qPCR for muscarinic receptor types 2 (M2) and 3 (M3), collagen type 1α1 and 3α1, and SM actin. Western blots measured M2 and M3 protein expression. Bladder sections were stained with Masson’s trichrome for SM content and immunofluorescence staining for nerve terminals expressing vesicular acetylcholine transporter (VAChT), tyrosine hydroxylase (TH), and neuronal nitric oxide synthase (nNOS). Results: Bilateral pelvic nerve injury caused larger bladders with less SM content and increased collagen type 1α1 and 3α1 gene expression. At early time points, cholinergic-mediated contraction increased, whereas EFS-mediated contraction decreased and returned to baseline by 30 days. Protein and gene expression of M3 was decreased 3 and 7 days post-BPNI, whereas M2 was unchanged. TH nerve terminals surrounding the detrusor decreased in all BPNI groups, whereas VAChT and nNOS terminals decreased 14 and 30 days post-BPNI. Conclusions: Bilateral pelvic nerve injury increased bladder size, impaired contractility, and decreased SM and autonomic innervation. Therapeutic strategies preventing nerve injury-mediated decline in neuronal input and SM content may prevent the development of a neurogenic bladder and improve quality of life after invasive pelvic surgery
