Acu-URO17 is a highly sensitive and specific bladder cancer biomarker.

Objective: This study evaluates the efficacy of Acu-URO17, a highly sensitive and specific immunocytochemistry (ICC) test targeting Keratin 17, in comparison to urine cytology and UroVysion™ fluorescence in situ hybridization (FISH) for detecting bladder cancer cells in voided urine specimens. Methods: Acupath conducted a large-scale comparison study using 2378 voided urine specimens. Acu-URO17, urine cytology and UroVysion™ FISH were performed on these specimens according to standardized protocols. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for Acu-URO17 in comparison to urine cytology and UroVysion™ FISH. Results: In cases diagnosed with high-grade urothelial cancer via urine cytology, Acu-URO17 demonstrated a sensitivity of 96% and a specificity of 82%. When compared to UroVysion™ FISH results, Acu-URO17 exhibited a sensitivity of 97.1% and a specificity of 77.8%, surpassing the sensitivity of UroVysion™ FISH (57.1%). Notably, Acu-URO17 showed a high NPV of 99.9%, indicating its reliability in confirming negative urine cytology results and risk-stratifying atypical and suspicious cytology results. Conclusion: The results of this large-scale prospective study support Acu-URO17 as a clinically relevant, non-invasive and cost-effective tool for detecting bladder cancer cells in voided urine specimens. Its high sensitivity, specificity and NPV make it a valuable adjunct to urine cytology and UroVysion™ FISH in the diagnosis and management of urothelial carcinoma (UC).

Exploring the unmet needs and experiences of informal caregivers of patients with end-stage kidney disease (ESKD) receiving haemodialysis - a qualitative study.

BACKGROUND: Patients with end stage kidney disease (ESKD) receiving haemodialysis experience multiple symptoms, which can present physical and emotional challenges for both patients and their informal caregivers. Caregivers can experience anxiety, depression, and social isolation negatively impacting their overall wellbeing and resulting in caregiver burden. The needs of this group of caregivers have been largely neglected, with little emphasis placed on supportive interventions that might assist and support them in their caring role. AIM: The aim of this study Is to explore the unmet needs and experiences of caregivers of patients with ESKD receiving haemodialysis, and to determine the components of a supportive intervention. DESIGN: A qualitative study using semi-structured interviews (n = 24) with informal caregivers. An interpretive qualitative framework was employed to generate a rich understanding of the unmet needs and experiences of caregivers. Data was analysed using thematic analysis. Interviews were transcribed verbatim and data management was assisted through NVIVO version 11. SETTING/PARTICIPANTS: Twenty-four informal caregivers were purposively recruited from two haemodialysis settings within Northern Ireland. RESULTS: Three themes were identified: (1) The negative impact of distress, anxiety, and isolation on caregivers due to their caregiving responsibilities (2) Inadequate information and knowledge about the complexities of renal care (3) The benefits of spiritual beliefs, stress management and peer support in relieving the caregiving burden. CONCLUSIONS: Caregivers of patients with ESKD receiving haemodialysis are at increased risk of physical and psychological distress and burden arising from their caregiving role. The unpredictable nature of ESKD and haemodialysis treatment negatively impacts the caregiver experience and adds to the challenges of the role. The information needs of caregivers are not always adequately met and they subsequently lack appropriate knowledge, skills, and guidance to assist them in their caregiving role. Supportive interventions are essential for caregivers to enhance their capability to deliver effective care and improve their quality of life.

Early Clinical Results Following Repair of Gluteal Tendon Tears.

Gluteal tendinopathy is a common source of impairment in adults due to degenerative changes in the gluteus medius tendon. We identified patients with gluteal tendinopathy who underwent surgery with a minimum six-month follow up. Radiographs, magnetic resonance images, demographic data, Hip Outcome Score (HOS), Veterans Rand 12-item health survey (VR-12), and a patient survey were reviewed. The cohort consisted of seventeen complete tears and thirty-one partial tears of the gluteal medius tendon (n = 48). Of patients, 72.9% reported satisfaction with surgery and noted 95.5% improvement in symptoms. Patients with partial tears demonstrated 90.0% improvement, while patients with complete tears noted 85% (p = 0.983). The median percent improvement for satisfied patients was 95.00 (85-100) and was significantly different from non-satisfied patients (p < 0.0001). Surgical repair resulted in higher HOS, activities of daily living (ADL), and HOS Sports scores. The majority of patients were satisfied with surgical treatment at follow up, noting near complete resolution in preoperative symptoms.

Development of a bioactive tunable hyaluronic-protein bioconjugate hydrogel for tissue regenerative applications.

Every year, there are approximately 500 000 peripheral nerve injury (PNI) procedures due to trauma in the US alone. Autologous and acellular nerve grafts are among current clinical repair options; however, they are limited largely by the high costs associated with donor nerve tissue harvesting and implant processing, respectively. Therefore, there is a clinical need for an off-the-shelf nerve graft that can recapitulate the native microenvironment of the nerve. In our previous work, we created a hydrogel scaffold that incorporates mechanical and biological cues that mimic the peripheral nerve microenvironment using chemically modified hyaluronic acid (HA). However, with our previous work, the degradation profile and cell adhesivity was not ideal for tissue regeneration, in particular, peripheral nerve regeneration. To improve our previous hydrogel, HA was conjugated with fibrinogen using Michael-addition to assist in cell adhesion and hydrogel degradability. The addition of the fibrinogen linker was found to contribute to faster scaffold degradation via active enzymatic breakdown, compared to HA alone. Additionally, cell count and metabolic activity was significantly higher on HA conjugated fibrinogen compared previous hydrogel formulations. This manuscript discusses the various techniques deployed to characterize our new modified HA fibrinogen chemistry physically, mechanically, and biologically. This work addresses the aforementioned concerns by incorporating controllable degradability and increased cell adhesivity while maintaining incorporation of hyaluronic acid, paving the pathway for use in a variety of applications as a multi-purpose tissue engineering platform.

Initial Experience With Subchondral Stabilization for Grade II Stress Fractures of the Midfoot and Forefoot.

Stress fractures of the foot are often preceded by magnetic resonance imaging evidence of bone marrow edema. While new evidence suggests intraosseous injection of calcium phosphate ("subchondral stabilization") can alleviate symptoms associated with bone marrow edema, no data yet exist regarding its use in developing mid- and forefoot stress fractures. Fifty-four patients who underwent subchondral stabilization of various midfoot/forefoot bones in our practice were observed over a 5-year period. All patients were unresponsive to standard nonoperative measures for at least 6 weeks, and all had clinical exams and advanced imaging consistent with a Kaeding-Miller Grade II stress fracture. Forty patients were included with a mean age of 54.3 ± 14.9 years and mean follow-up of 14.1 ± 6.9 months. Patients saw a significant decrease in visual analog scale (VAS) pain as early as 1 month postoperatively (p < .05). Mean postoperative VAS at 12 months was 2.11 ± 2.50, and mean reduction in VAS pain from preoperative to 12 months postoperative was -5.00 (95% CI -3.44 to -6.56, p < .05). Fourteen patients (34%, 14/41) were entirely pain free at 12 months. Higher preoperative VAS pain scores (unadjusted odds ratio [OR] 2.13 [95% CI 1.20-3.77], p = .010) and treatment of more than 1 bone (unadjusted OR 6.23 [95% CI 1.39-27.8], p = .017) were associated with a greater likelihood of not achieving a pain free status at 12 months. Our initial experience with subchondral stabilization suggests the procedure may be safe and effective for use in many Kaeding-Miller Grade II stress fractures of the mid- and forefoot.

Grit and uncertainty: Grit predicts performance and West Point graduation during pandemic conditions.

Grit, or the passionate pursuit of long-term goals, is an important predictor of performance and success across various domains, including within some military contexts. Whether grit predicts such outcomes at a military service academy during a multi-year period of prolonged uncertainty, however, is unknown. Using institutional data collected prior to the COVID-19 pandemic onset, we assessed how well grit, physical fitness test scores, and entrance examination scores predicted performance in academic, military, and physical domains, as well as on-time graduation for 817 cadets from the West Point Class of 2022. This cohort spent more than 2 years of their time at West Point functioning under the uncertainty of pandemic-related conditions. Multiple regression results showed that grit, fitness test, and entrance examination scores were all significant predictors of performance outcomes in the academic, military, and physical domains. Results from binary logistic regression showed that, in addition to physical fitness, grit scores significantly predicted graduation from West Point and accounted for unique variance. Consistent with results from pre-pandemic studies, grit was an important predictor of performance and success for West Point cadets even under pandemic conditions.

Postpartum Opportunistic Salpingectomy Compared With Bilateral Tubal Ligation After Vaginal Delivery for Ovarian Cancer Risk Reduction: A Cost-Effectiveness Analysis.

OBJECTIVE: To compare the cost effectiveness of opportunistic salpingectomy and bilateral tubal ligation for sterilization immediately after vaginal delivery. METHODS: A cost-effectiveness analytic decision model was used to compare opportunistic salpingectomy with bilateral tubal ligation during vaginal delivery admission. Probability and cost inputs were derived from local data and available literature. Salpingectomy was assumed to be performed with a handheld bipolar energy device. The primary outcome was the incremental cost-effectiveness ratio (ICER) in 2019 U.S. dollars per quality-adjusted life-year (QALY) at a cost-effectiveness threshold of $100,000/QALY. Sensitivity analyses were performed to determine the proportion of simulations in which salpingectomy would be cost effective. RESULTS: Opportunistic salpingectomy was more cost effective than bilateral tubal ligation with an ICER of $26,150/QALY. In 10,000 patients desiring sterilization after vaginal delivery, opportunistic salpingectomy would result in 25 fewer ovarian cancer cases, 19 fewer ovarian cancer deaths, and 116 fewer unintended pregnancies than bilateral tubal ligation. In sensitivity analysis, salpingectomy was cost effective in 89.8% of simulations and cost saving in 13% of simulations. CONCLUSION: In patients undergoing sterilization immediately after vaginal deliveries, opportunistic salpingectomy is more cost effective and may be more cost saving than bilateral tubal ligation for reducing ovarian cancer risk.

Comparison of Regenerative Injection Therapy and Conventional Therapy for Proximal Plantar Fasciitis.

Treatment of subacute and chronic heel pain often presents a unique challenge to the physician. Regenerative therapies, such as injectable amnion and connective tissue matrix, may represent a promising new approach in these patients, and have become increasingly popular in the United States. However, little literature exists evaluating these injections compared to conventional nonoperative means. As such, we designed a retrospective comparative study evaluating patients in our practice who received a standardized plantar fascial treatment protocol only (standard therapy), and those who received regenerative plantar fascial injections in addition to standard therapy. A total of 54 patients were followed over a 3-month observation period (91.7 ± 73.9 days), with numeric pain rating (NPR) serving as the primary outcome. Both groups saw an improvement in NPR at the end of the observation period, but patients in the regenerative therapy group demonstrated lower pain scores than those receiving standard therapy alone (mean NPR 2.1 ± 2.3 vs 4.4 ± 2.8, p = .004). Additionally, those in the standard therapy group were significantly more likely to proceed onto surgical intervention compared to the regenerative therapy group (unadjusted odds ratio 15.6, 95% CI 3.0-27.9). The use of regenerative injections for subacute and chronic plantar fasciitis showed promise in our study, and may help mitigate against the need for invasive surgical intervention.

Comparison of DXA-based versus CT-based indices to predict prevalent fracture history in men with spinal cord injury.

Fracture risk prediction remains challenging in adults with spinal cord injury. Here, we compare the ability of CT- and DXA-derived indices to discriminate between those with and without prevalent osteoporotic fracture. Novel CT-derived indices may offer improved assessment of fragility fracture risk as well as improved monitoring of response to therapies. INTRODUCTION: Individuals with spinal cord injury are particularly susceptible to osteoporosis. As advanced imaging techniques become more readily available clinically, there is limited information on the relative strength of various outcomes for fracture risk prediction. The purpose of this study was to compare the ability of DXA-based versus CT-based indices to predict prevalent fracture history in adults with spinal cord injury. METHODS: Thirty-six men with known SCI underwent dual energy X-ray absorptiometry and computed tomography assessments of the lower extremities. We used age-adjusted area under the curve models to compare the predictive value for each bone parameter to identify prevalent fracture history. RESULTS: CT-based indices outperformed DXA-based indices at all sites. The site with the highest AUC was the trabecular BMD at the proximal tibial epiphysis. CONCLUSIONS: CT imaging may have clinical utility to improve fracture risk prediction in adults with SCI. More work is needed to confirm these findings and to assess the value of CT-based indices to predict incident fracture, monitor longitudinal bone loss, and monitor response to various therapies, both pharmacological and rehabilitation.

The Relationship Among Chronotype, Hardiness, Affect, and Talent and Their Effects on Performance in a Military Context.

Individual preference for morning or evening activities (chronotype), affect, hardiness, and talent are associated with a variety of performance outcomes. This longitudinal study was designed to investigate the degree to which these variables are associated with academic, physical, and military performance. Self-reported measures of chronotype, affect, and hardiness were collected from 1149 cadets from the Class of 2016 upon entry to the United States Military Academy. Talent, a composite of academic, leadership, and physical fitness scores were drawn from cadet records. Academic, military, and physical performance measures were collected at graduation 4 years later. The results indicated that a morning orientation was associated with better physical and military performance. Higher talent scores, as well as lower levels of negative affect, were associated with better performance across all three performance measures. Hardiness was only associated with military performance. The findings suggest that a morning orientation and less negative affect may result in better performance overall within a challenging and structured military environment. Future studies of chronotype shifts may provide further insight into associated performance benefits.

Thomas Kuhn and Science Education: Learning from the Past and the Importance of History and Philosophy of Science.

Beginning 60 years ago, Thomas Kuhn has had a significant impact across the academy and on culture more widely. And he had a great impact on science education research, theorising, and pedagogy. For the majority of educators, the second edition (1970) of his Structure of Scientific Revolutions (Kuhn, 1970a) articulated the very nature of the science, the discipline they were teaching. More particularly, Kuhn's book directly influenced four burgeoning research fields in science education: Children's Conceptual Change, Constructivism, Science-Technology-Society studies, and Cultural Studies of Science Education. This paper looks back to the Kuhnian years in science education and to the long shadow they cast. The discipline of science education needs to learn from its past so that comparable mistakes might be averted in the future. Kuhn's influence was good and bad. Good, that he brought HPS to so many; bad, that, on key points, his account of science was flawed. This paper will document the book's two fundamental errors: namely, its Kantian-influenced ontological idealism and its claims of incommensurability between competing paradigms. Both had significant flow-on effects. Although the book had many positive features, this paper will document how most of these ideas and insights were well established in HPS literature at the time of its 1962 publication. Kuhn was not trained in philosophy, he was not part of the HPS tradition, and to the detriment of all, he did not engage with it. This matters, because before publication he could have abandoned, modified, or refined much of his 'revolutionary' text. Something that he subsequently did, but this amounted to closing the gate after the horse had bolted. In particular, the education horse had well and truly bolted. While educators were rushing to adopt Kuhn, many philosophers, historians, and sociologists were rejecting him. Kuhn did modify and 'walk back' many of the head-turning, but erroneous, claims of Structure. But his retreat went largely unnoticed in education, and so the original, deeply flawed Structure affected the four above-mentioned central research fields. The most important lesson to be learnt from science education's uncritical embrace of Kuhn and Kuhnianism is that the problems arose not from personal inadequacies; individuals are not to blame. There was a systematic, disciplinary deficiency. This needs to be addressed by raising the level of philosophical competence in the discipline, beginning with the inclusion of HPS in teacher education and graduate programmes.

Why Hasn't the Gifted Label Caught up with Science?

The development of both special education and gifted education as fields of study were closely tied to the origins of intelligence testing in the early 20th century. While special education's terminology has become more nuanced and circumspect over the ensuing century, the term gifted has remained unchanged despite coming under substantial criticism in recent decades for its lack of specificity and for the innateness that the term implies as the primary cause of individual differences in ability. We examine this history and the seminal nationally disseminated reports related to gifted education, from the Marland report to the present, to consider why the gifted label has persisted. We conclude with some suggestions for how these issues might be remedied.

Multiomic analysis reveals conservation of cancer-associated fibroblast phenotypes across species and tissue of origin.

Cancer-associated fibroblasts (CAFs) are integral to the solid tumor microenvironment. CAFs were once thought to be a relatively uniform population of matrix-producing cells, but single-cell RNA sequencing has revealed diverse CAF phenotypes. Here, we further probed CAF heterogeneity with a comprehensive multiomics approach. Using paired, same-cell chromatin accessibility and transcriptome analysis, we provided an integrated analysis of CAF subpopulations over a complex spatial transcriptomic and proteomic landscape to identify three superclusters: steady state-like (SSL), mechanoresponsive (MR), and immunomodulatory (IM) CAFs. These superclusters are recapitulated across multiple tissue types and species. Selective disruption of underlying mechanical force or immune checkpoint inhibition therapy results in shifts in CAF subpopulation distributions and affected tumor growth. As such, the balance among CAF superclusters may have considerable translational implications. Collectively, this research expands our understanding of CAF biology, identifying regulatory pathways in CAF differentiation and elucidating therapeutic targets in a species- and tumor-agnostic manner.

Evaluation of a Programme of Online Arts Activities for Patients with Kidney Disease during the COVID-19 Pandemic.

Patients living with end-stage kidney disease (ESKD) have been seriously impacted by the COVID-19 pandemic. As these patients are considered extremely clinically vulnerable, they were advised to 'shield' at home, with limited face-to-face contact and support for the duration of the pandemic. Living with ESKD impacts heavily on patients' mental health and wellbeing, and this extended period of isolation and loneliness is likely to have a further negative effect on patients' mental wellbeing. The Renal Arts Group (RAG), Queen's University Belfast, aims to improve the quality of life of those living with ESKD and the extended renal community through engagement with the arts. We developed an initiative, funded by the Economic and Social Research Council, and carried out an evaluation. The initiative included a programme of online arts-based activities that built upon the work of RAG and provided mental wellbeing support for patients who faced an extended, lonely period of self-isolation. We worked with experienced arts practitioners to identify appropriate activities and developed five workshops and tutorials that were delivered online. We received positive feedback from participants who found the activities to be enjoyable, beneficial to their mental wellbeing and were interested in undertaking further activities online. We conducted interviews with the arts facilitators and identified three themes for consideration when developing online arts activities for the renal community. Participants reported that the activities benefited their mental wellbeing, were enjoyable and provided an opportunity to meet others with shared interests. The arts facilitators reported experiences around accessibility, audience engagement, impact on health and wellbeing and facilitator experience, that should be considered when developing online arts activities for the renal community. This evaluation will inform future work in this area, and the arts tutorial videos developed as part of this project will remain available online for members of the renal community to access.

An Unusual Case of Infantile Hepatic Steatosis Caused by Coconut-Based Infant Formula.

Clinical Assessment of Dialysis Recovery Time and Symptom Burden: Impact of Switching Hemodialysis Therapy Mode.

INTRODUCTION: Most people on hemodialysis (HD) report a high symptom burden. Fatigue and lack of energy are prominent, interfering with daily life and associated with poor outcome. Prolonged recovery time after each of the thrice weekly dialysis treatments is common. The impact of HD therapies, like expanded hemodialysis (HDx), on patient reported recovery time and symptom burden is unclear. METHODS: A dialysis unit decided to perform regular assessments of patient-reported symptom burden, using the POS-S Renal Symptom questionnaire and the "Recovery time from last dialysis session" question as part of routine patient focused care. At a similar time, a clinical evidence-based decision was taken to switch the in-center dialysis cohort from regular high-flux dialysis membrane to medium cut-off (MCO) membrane, introducing HDx therapy. RESULTS: Quarterly assessment of patient-reported symptom burden was well accepted. A sustained clinically relevant reduction in post-dialysis recovery time was observed following the therapy switch. In patients providing data up to 12 months (N = 58), median recovery time decreased from 210 min (IQR 7.5-600) to 60 min (0-210; p = 0.002) and 105 min (0-180; p = 0.001) at 6 and 12 months, respectively. Thirty-six percent of individuals reported a recovery time longer than 360 minutes at the initial assessment, which decreased to 9% at 12 months. The POS-S Renal total symptom score showed a decrease at 6 months but no difference from baseline at 12 months. The "fatigue/lack of energy" symptom showed a sustained improvement; the percentage of participants scoring its impact as "severe" or "overwhelming" decreased from 28% at baseline to 16% at 12 months. Changes in other symptoms were more variable. CONCLUSION: Regular assessment of patient reported symptoms is feasible in routine dialysis practice and can help in evaluating the impact of clinical interventions. Observations suggest that HDx therapy may reduce post-dialysis recovery time and improve perceived fatigue level.

Development of a complex arts-based intervention for patients with end-stage kidney disease whilst receiving haemodialysis.

BACKGROUND: Patients with end-stage kidney disease who receive haemodialysis experience a protracted treatment regimen that can result in an increased risk of depression and anxiety. Arts-based interventions could address this unique issue; however, no arts-based interventions have been developed for delivery within a haemodialysis unit and evaluation within a randomised controlled trials (RCTs). AIM: To develop a complex arts-based intervention for patients with end-stage kidney disease whilst receiving haemodialysis. METHODS: The development process utilised the Arts in Health framework (Fancourt, 2017). The framework was addressed through the establishment of an interdisciplinary advisory group, collaboration and consultation with stakeholders, a scoping and realist review, shadowing of artists-in-residence, personal arts practice and logic modelling. RESULTS: The intervention involved six 1-h long, one-to-one facilitated sessions focused on creative writing and visual art. Patients could choose between art form and self-select a subject matter. The sessions had a primary focus on skill development and were delivered using principles derived from the psychological theory of flow. CONCLUSION: The Arts in Health framework provided an appropriate and pragmatic approach to intervention development. Complex arts-based interventions can be developed for the purpose of evaluation within a trial framework. This intervention was designed to strike a balance between standardised components, and a person-centred approach necessary to address existential boredom.

A nonrandomised pilot study to examine the feasibility and acceptability of reflexology in patients undergoing hospital-based haemodialysis (solitude study).

BACKGROUND: Patients with end-stage kidney disease, receiving haemodialysis can experience complications-hypotension, headache, muscle cramp, chest pain, nausea and vomiting. Patients who experience all or some of these symptoms will often report reduced health-related quality of life (HRQOL) and poor sleep quality, which may lead to increased morbidity and mortality. OBJECTIVE: The objective of this pilot study is to evaluate the feasibility of a larger randomised controlled trial to determine the effect of foot reflexology on a cohort of patients undergoing hospital-based haemodialysis. DESIGN: A nonrandomised pilot study using a multimethod approach. PARTICIPANTS: Twenty patients undergoing hospital-based haemodialysis treatment. MEASUREMENTS: HRQOL and quality of sleep were measured using the SF-12 Health Survey and the Pittsburgh Sleep Quality Index (PSQI). Semi-structured interviews were completed with 10 patients, exploring their experiences, opinions and perceptions of the intervention. RESULTS: There was an increase in the mean scores examining the total physical health and mental health components of the SF-12. All corresponding p values were statistically significant following the intervention. The mean total sleep score postintervention signified positive changes in sleep quality, with the corresponding p values being statistically significant. The study established the feasibility of the intervention and the benefits for patients undergoing haemodialysis. CONCLUSION: This pilot study demonstrated the possibility of recruiting and retaining patients undergoing haemodialysis to a reflexology study. The study did not impact the haemodialysis routine and was positively received. The intervention showed statistically significant improvements in patients' HRQOL and sleep quality.

Improving college students' fact-checking strategies through lateral reading instruction in a general education civics course.

College students lack fact-checking skills, which may lead them to accept information at face value. We report findings from an institution participating in the Digital Polarization Initiative (DPI), a national effort to teach students lateral reading strategies used by expert fact-checkers to verify online information. Lateral reading requires users to leave the information (website) to find out whether someone has already fact-checked the claim, identify the original source, or learn more about the individuals or organizations making the claim. Instructor-matched sections of a general education civics course implemented the DPI curriculum (N = 136 students) or provided business-as-usual civics instruction (N = 94 students). At posttest, students in DPI sections were more likely to use lateral reading to fact-check and correctly evaluate the trustworthiness of information than controls. Aligning with the DPI's emphasis on using Wikipedia to investigate sources, students in DPI sections reported greater use of Wikipedia at posttest than controls, but did not differ significantly in their trust of Wikipedia. In DPI sections, students who failed to read laterally at posttest reported higher trust of Wikipedia at pretest than students who read at least one problem laterally. Responsiveness to the curriculum was also linked to numbers of online assignments attempted, but unrelated to pretest media literacy knowledge, use of lateral reading, or self-reported use of lateral reading. Further research is needed to determine whether improvements in lateral reading are maintained over time and to explore other factors that might distinguish students whose skills improved after instruction from non-responders.
