Transformative impacts of a civic leadership program created by and for refugees and immigrants.

Immigrants and refugees are severely underrepresented at all levels of political decision-making in the United States. These groups face significant barriers to civic and political participation and leadership, despite a frequent commitment to community care and engagement. There is an urgent need to address immigrant integration and underrepresentation through transformative means that go beyond voting to create a more inclusive and socially just society. We investigated outcomes associated with participation in an immigrant integration program designed to increase immigrants' access to civic engagement through a community-based participatory research and action process that centered the voices, experiences, and wisdom of refugees and immigrants. Thirty immigrants and refugees representing at least eight different communities participated in semi-structured interviews. Results illustrate how the program assisted in transforming participants' consciousness, skills, and relationships related to meaningful civic engagement and realizing their voice, power, and rights. These results emphasize the impact and potential of community based participatory research to transform individual and collective efficacy, consciousness, and capabilities-a vital first step in transformative justice.

Hierarchical Organization of Single Crystal Polymorphs of Azobenzene Chromophore in Anisotropic Media Subjected to Local Thermal Gradients upon Cold Spraying.

The present article entails the emergence of diverse crystal polymorphs following thermal quenching into various coexistence regions of binary azobenzene chromophore (ACh)/diacrylate (DA) solution and of azobenzene/nematic liquid crystal (E7) mixture. Development of various crystal topologies encompassing rhomboidal and hexagonal shapes can be witnessed in a manner dependent on thermal quenched depths into the crystal + liquid coexistence region of ACh/DA system. Upon spraying with compressed carbon dioxide (CO2 ) fluid, the local temperature gradient is generated resulting in spherulitic morphology showing discrete lamellae undergoing twisting locally in some regions and branched dendrites or seaweeds in another. When ACh/E7 blend is sprayed using compressed CO2 fluid, hierarchical organization of various discrete faceted single crystals including needle, rectangular, rhombus, and truncated hexagonal crystals radiating from the spherulite core can be discerned in a brighter region (off cross-polarization) polarized optical microscopy (POM) and nematic disclination in a darker cross-polarized region. Of particular interest is that the observed faceted single-crystal polymorphs in ACh/E7 may be contrasted to the lamellar twisting and branching observed in the ACh/DA system and plausible mechanisms of polymer spherulitic growth are discussed.

Trans-arterial embolization of renal cell carcinoma: a systematic review and meta-analysis.

PURPOSE: To evaluate if trans-arterial embolization (TAE) of the primary tumor in patients with renal cell carcinoma (RCC) improves symptomatology such as pain and hematuria or oncologic outcomes such as progression-free survival (PFS) and overall survival (OS). MATERIALS AND METHODS: The systematic review search included PubMed, Ovid/MEDLINE, and Embase for full-text English articles including randomized and non-randomized prospective trials as well as prospective and retrospective case series. To be included, prospective trials needed ≥ 25 patients in each arm while case series and retrospective chart reviews required at least two patients. Evaluated outcomes included PFS, OS, change in tumor size, improvements in pain, improvements in hematuria, and adverse events (AEs). RESULTS: 1327 articles were retrieved and screened. Nine studies met inclusion criteria (retrospective case series, n = 8; non-randomized prospective trial, n = 1) which included 237 patients (M = 156 (65.8%); F = 56 (23.6%); gender unreported = 25 (10.5%); mean age: 69.4 (range: 38-87)) with a mean tumor diameter of 9.3 cm (5.2-10.5). When reported, the TNM stages were stage I (n = 10), II (n = 18), III (n = 36), and IV (n = 121). 60 patients were treated for pain and hematuria. After TAE, pain improved in 59 patients (98.3%) and hematuria improved in 57 patients (95%). A meta-analysis for improvements in pain and hematuria demonstrated an event rate of pain improvement of 0.952 (0.788-0.990; p < 0.001) and an event rate for hematuria improvement of 0.923 (0.809-0.971; p < 0.001). Median OS ranged from 1 to 39 months but only one study reported PFS (10.5 months). Only one study demonstrated a statistically significant improvement in OS with TAE when compared with patients that did not undergo TAE (p = 0.02). A reduction in tumor size was only achieved in 17 patients (17/49; 34.7%) limiting evaluation. AEs included fever (n = 115/237; 48.5%), flank pain (n = 72/237; 30.4%), nausea (n = 58/237; 24.5%), hematuria (n = 12/237; 5.1%), hypertension (n = 12/237; 5.1%), reduced GFR (n = 6/237; 2.5%), hematoma (n = 6/237,2.5%), and ileus (n = 3/237; 1.3%). CONCLUSION: TAE monotherapy of the primary tumor in patients with RCC improves symptomatology such as pain and hematuria with an acceptable safety profile.

Creating collective solidarity: Insights from the development and process evaluation of civic action for refugee empowerment in Cincinnati.

OBJECTIVE: Our goal was to describe the development, progress, and functioning of Civic Action for Refugee Empowerment in Cincinnati (CARE: Cincinnati) as a model for community-based participatory research (CBPR) with refugees. We conducted a participatory evaluation to assess our collective ability to employ shared power and equitable decision-making, and to facilitate structures that build member ownership and solidarity. We identify principles and processes that can be used by researchers, practitioners, and activists interested in working toward the creation of more equitable community spaces for refugees. METHOD: Twelve refugee research team members representing seven different countries and ranging in age from 16 to 75 engaged in the participatory evaluation and are coauthors of this manuscript. All participants were interviewed by an external researcher, who transcribed and anonymized responses. Academic researchers first developed preliminary themes and then the entire research team verified, prioritized, and expanded themes. RESULTS: The experiences of refugee team members illustrate an iterative process of reflection and action that are both personally satisfying and encourage work for deeper change. The themes further illustrate that the CBPR process aided in developing a sense of solidarity among diverse team members and that the dynamic and participatory organization of the group fostered equitable and creative decision-making. CONCLUSIONS: Our participatory evaluation suggests that future research partnering with refugees that brings together diverse teams to share power will not only improve research quality and dissemination, but will also serve as a tangible benefit for refugee team members. The shared reflection, analysis, and action process inherent in the research process are individually motivating to refugee team members and foster possibility for transformative change.

STARD Adherence in an Interventional Radiology Guideline for Diagnostic Arteriography.

Objective: To assess the quality of reporting in diagnostic accuracy studies (DAS) referenced by the Quality Improvement Guidelines for Diagnostic Arteriography and their adherence to the Standards for Reporting of Diagnostic Accuracy (STARD) statement.Materials and Methods: Citations specific to the Society of Interventional Radiology's Quality Improvement Guidelines for Diagnostic Arteriography were collected. Using the 34-item STARD checklist, two authors in a duplicate and blinded fashion documented the number of items reported per diagnostic accuracy study. Authors met, and any discrepancies were resolved in a resolution meeting.Results: Of the 26 diagnostic accuracy studies included, the mean number of STARD items reported was 17.8 (SD ± 3.1). The median adherence was 18 (IQR, 17-19) items. Ten articles were published prior to 2003, the original date of STARD publication, and 16 articles were published after 2003. The mean number of reported items for the articles published prior to STARD 2003, and after STARD 2003 was 17.4 (SD ± 2.4) and 18.1 (SD ± 3.5), respectively. There were 14 STARD items that demonstrated an adherence of < 25%, and 13 an adherence > 75%.Conclusion: The dichotomous distribution of adherence to the STARD statement by DAS investigated demonstrates that areas of deficient reporting may be present and require attention to ensure complete and transparent reporting in the future.

Evaluation of indicators supporting reproducibility and transparency within cardiology literature.

OBJECTIVES: It has been suggested that biomedical research is facing a reproducibility issue, yet the extent of reproducible research within the cardiology literature remains unclear. Thus, our main objective was to assess the quality of research published in cardiology journals by assessing for the presence of eight indicators of reproducibility and transparency. METHODS: Using a cross-sectional study design, we conducted an advanced search of the National Library of Medicine catalogue for publications in cardiology journals. We included publications published between 1 January 2014 and 31 December 2019. After the initial list of eligible cardiology publications was generated, we searched for full-text PDF versions using Open Access, Google Scholar and PubMed. Using a pilot-tested Google Form, a random sample of 532 publications were assessed for the presence of eight indicators of reproducibility and transparency. RESULTS: A total of 232 eligible publications were included in our final analysis. The majority of publications (224/232, 96.6%) did not provide access to complete and unmodified data sets, all 229/232 (98.7%) failed to provide step-by-step analysis scripts and 228/232 (98.3%) did not provide access to complete study protocols. CONCLUSIONS: The presentation of studies published in cardiology journals would make reproducing study outcomes challenging, at best. Solutions to increase the reproducibility and transparency of publications in cardiology journals is needed. Moving forward, addressing inadequate sharing of materials, raw data and key methodological details might help to better the landscape of reproducible research within the field.

Uniting liberatory and participatory approaches in public psychology with refugees.

Increasing inequities both within and between nations call psychologists to consider whom they intend their research and practice to serve. The purpose of this article is to propose a public psychology rooted in the values of liberation psychology and utilizing participatory research methods to enact change. To exemplify this framework, we present the work of a community research partnership between academics and individuals with lived experience as refugees. All aspects of our research process, including the development of research questions and design, data collection and analysis, and dissemination and action planning, have been conducted via community-academic collaboration. Our focus has been to gain understanding of the strengths and concerns of Cincinnati's diverse refugee communities to inform actions promoting civic engagement. Refugee coresearchers successfully administered a collectively developed survey to 291 refugees in seven languages and facilitated follow-up focus groups with 35 people. Additionally, refugee coresearchers have identified three action plans based on the research findings to promote civic engagement; thus, translating research into meaningful action. This article details phases of our research process and interprets findings in the context of liberation psychology to illustrate the benefits of public psychology for academia, social policy, and community practice. We also discuss how our research illustrates the ways public psychology has the potential to not only promote greater equity but also to improve science.

An analysis of key indicators of reproducibility in radiology.

BACKGROUND: Given the central role of radiology in patient care, it is important that radiological research is grounded in reproducible science. It is unclear whether there is a lack of reproducibility or transparency in radiologic research. PURPOSE: To analyze published radiology literature for the presence or lack of key indicators of reproducibility. METHODS: This cross-sectional retrospective study was performed by conducting a search of the National Library of Medicine (NLM) for publications contained within journals in the field of radiology. Our inclusion criteria were being MEDLINE indexed, written in English, and published from January 1, 2014, to December 31, 2018. We randomly sampled 300 publications for this study. A pilot-tested Google form was used to record information from the publications regarding indicators of reproducibility. Following peer-review, we extracted data from an additional 200 publications in an attempt to reproduce our initial results. The additional 200 publications were selected from the list of initially randomized publications. RESULTS: Our initial search returned 295,543 records, from which 300 were randomly selected for analysis. Of these 300 records, 294 met inclusion criteria and 6 did not. Among the empirical publications, 5.6% (11/195, [3.0-8.3]) contained a data availability statement, 0.51% (1/195) provided clear documented raw data, 12.0% (23/191, [8.4-15.7]) provided a materials availability statement, 0% provided analysis scripts, 4.1% (8/195, [1.9-6.3]) provided a pre-registration statement, 2.1% (4/195, [0.4-3.7]) provided a protocol statement, and 3.6% (7/195, [1.5-5.7]) were pre-registered. The validation study of the 5 key indicators of reproducibility-availability of data, materials, protocols, analysis scripts, and pre-registration-resulted in 2 indicators (availability of protocols and analysis scripts) being reproduced, as they fell within the 95% confidence intervals for the proportions from the original sample. However, materials' availability and pre-registration proportions from the validation sample were lower than what was found in the original sample. CONCLUSION: Our findings demonstrate key indicators of reproducibility are missing in the field of radiology. Thus, the ability to reproduce studies contained in radiology publications may be problematic and may have potential clinical implications.

High correlation between mechanical properties and bone mineral parameters in embalmed femurs after long-term storage.

BACKGROUND: Fresh frozen human femurs are considered "the gold standard" in biomechanical studies of hip fractures, resembling the in vivo situation mostly. A more readily available alternative is formalin embalmed femurs. However, to which extent formalin affects key features of bone; its mechanical properties, bone mineral content and their mutual relationship over time, remains unknown. Accordingly, we measured the mineral parameters and related them to the mechanical properties of formalin fixed femurs after long-term storage. METHODS: 36 paired femurs from human donors, fixed in formalin and stored for a mean period of 4.6 (3.5-6) years. Quantitative CT was performed to measure the bone mineral density and mass at the mainly cortical mid shaft and the center of the mainly cancellous condyles. Each pair was subjected to local tests by three-point bending and screw pullout of the shaft and lateral punch and metaphyseal cube compression of the condyles. FINDINGS: Neither mechanical nor bone mineral data were significantly correlated to storage time. Well-known associations for bone parameters with age and gender were retrieved. Maximum force of the cortical bone tests was highly correlated to the diaphyseal bone mass; (r = 0.80-0.87, p = 0.01), while maximum force of the cancellous bone tests correlated well to the density of the condylar bone; (r = 0.70, p = 0.01). INTERPRETATION: Our results indicate that mechanical and bone mineral data and their mutual relationship are conserved in formalin fixed femurs even after long-term storage. Formalin fixed femurs may serve as an alternative to fresh frozen femurs in biomechanical testing.

Feasibility of detecting orthopaedic screw overtightening using acoustic emission.

A preliminary study of acoustic emission during orthopaedic screw fixation was performed using polyurethane foam as the bone-simulating material. Three sets of screws, a dynamic hip screw, a small fragment screw and a large fragment screw, were investigated, monitoring acoustic-emission activity during the screw tightening. In some specimens, screws were deliberately overtightened in order to investigate the feasibility of detecting the stripping torque in advance. One set of data was supported by load cell measurements to directly measure the axial load through the screw. Data showed that acoustic emission can give good indications of impending screw stripping; such indications are not available to the surgeon at the current state of the art using traditional torque measuring devices, and current practice relies on the surgeon's experience alone. The results suggest that acoustic emission may have the potential to prevent screw overtightening and bone tissue damage, eliminating one of the commonest sources of human error in such scenarios.

Assessment of harbor seal predation on adult salmonids in a Pacific Northwest estuary.

The populations of many native species have increased or expanded in distribution in recent decades, sometimes with negative consequences to sympatric native species that are rarer or less adaptable to anthropogenic changes to the environment. An example of this phenomenon from the Pacific Northwest is predation by locally abundant pinnipeds (seals and sea lions) on threatened, endangered, or otherwise depleted salmonid (Oncorhynchus spp.) populations. We used survey sampling methodology, acoustic telemetry, and molecular genetics to quantify the amount of harbor seal (Phoca vitulina) predation on a depressed run of coho salmon (O. kisutch) and to determine whether some seals consumed a disproportionately higher number of salmonids than others. Based on a probability sample totaling 759.5 h of observation, we estimated that seals consumed 1161 adult salmonids (95% CI = 503-1818 salmonids) during daylight hours over an 18.9-km estuarine study area in Oregon during an 84-d period in fall 2002. Simultaneous tracking of 56 seals via an acoustic telemetry array indicated that a small proportion of marked seals (12.5%) exhibited behavior that was consistent with specialization on salmonids. These seals spent the majority of their time in the riverine portion of the study area and did so disproportionately more at night than day. Genetic analysis of 116 salmonid structures recovered from 11 seal fecal samples suggested that coho salmon accounted for approximately one-half of total salmonid consumption. Though subject to considerable uncertainty, the combined results lead us to infer that seals consumed 21% (range = 3-63%) of the estimated prespawning population of coho salmon. We speculate that the majority of the predation occurred upriver, at night, and was done by a relatively small proportion of the local seal population. Understanding the extent and nature of pinniped predation can provide important inputs into risk assessments and other modeling efforts designed to aid the conservation and recovery of salmonids in the Pacific Northwest. Such understanding may also help inform management actions designed to reduce the impact of pinniped predation on salmonids, which potentially range from short-term lethal removal programs to long-term ecosystem restoration and protection efforts.
