Ozone pollution contributes to the yield gap for beans in Uganda, East Africa, and is co-located with other agricultural stresses

Air quality negatively impacts agriculture, reducing the yield of staple food crops. While measured data on African ground-level ozone levels are scarce, experimental studies demonstrate the damaging impact of ozone on crops. Common beans (Phaseolus vulgaris), an ozone-sensitive crop, are widely grown in Uganda. Using modelled ozone flux, agricultural surveys, and a flux-effect relationship, this study estimates yield and production losses due to ozone for Ugandan beans in 2015. Analysis at this scale allows the use of localised data, and results can be presented at a sub-regional level. Soil nutrient stress, drought, flood risk, temperature and deprivation were also mapped to investigate where stresses may coincide. Average bean yield losses due to ozone were 17% and 14% (first and second growing season respectively), equating to 184 thousand tonnes production loss. However, for some sub-regions, losses were up to 27.5% and other crop stresses also coincided in these areas. This methodology could be applied widely, allowing estimates of ozone impact for countries lacking air quality and/or experimental data. As crop productivity is below its potential in many areas of the world, changing agricultural practices to mitigate against losses due to ozone could help to reduce the crop yield gap.

Impact of the COVID-19 Pandemic on Cancer Patient Educators

Patient education (PE) is vital in reducing anxiety, increasing satisfaction with treatment, helping with self-management, and creating a sense of control for cancer patients. Patients access much of their material from health care providers through in-person visits, patient libraries, and in-person classes. Due to reductions in in-person visits throughout the pandemic, we sought to understand how PE programs responded under varying levels of COVID-19 restrictions to meet the information needs of patients and families. A cross-sectional survey was distributed to members of the Cancer Patient Education Network (CPEN) and the Health Care Education Association (HCEA) via the respective listservs. The survey consisted of five sections that included closed and opened questions. Participants were asked questions to describe their PE programs and how their duties were affected during the pandemic. Forty-two CPEN members completed the survey (N = 42, 66%) with a 35% response rate and a 55% completion rate, and 19 HCEA members completed the survey (N = 19, 30%) with a 5% response rate and 16% completion rate. The majority of staff surveyed were not furloughed (N = 57/64, 89%). Just under half reported a change in daily PE program activities (N = 23/52, 44%) and most reported a change in developing PE materials (e.g., pamphlets) (N = 10/26, 63%), finding information for patients/families (N = 11/19, 58%), and delivering classes (N = 12/21, 57%). COVID-19 has ushered in a new era in the delivery of PE with the rapid deployment of digital cancer patient education. Results can inform future directions for the delivery of PE post-pandemic.

Bringing Patient and Caregivers Voices to the Clinical Trial Chorus: A Report From the BMT CTN Patient and Caregiver Advocacy Task Force

The Blood and Marrow Transplant Clinical Trials Network (BMT CTN), funded by the National Heart, Lung, and Blood Institute and the National Cancer Institute for more than 2 decades, is focused on improving the outcomes of hematopoietic cell transplantation (HCT) and other cellular therapies. It answered critical questions about conditioning intensity, donor choice, graft-versus-host disease prevention and treatment, and relapse mitigation strategies in a manner made possible by an extensive network of centers that have enrolled more than 16,000 patients to more than 55 trials. Although the BMT CTN has engaged patients in a variety of ways since its establishment, there is a growing realization that increasing that engagement and including caregivers offers many additional benefits to patients and investigators alike. Bringing the voice of patients and caregivers to clinical trial design is likely to enhance trial participation and reduce barriers to recruitment/retention. Unless clinical trials are designed with unique considerations of patients who have socioeconomic and access challenges, these populations will remain under-represented in HCT trials with limited generalizability of results. The next main frontier in our field is patient and caregiver access to high-quality HCT facilities coupled with the opportunity to participate in relevant, meaningful clinical research. In 2021, the BMT CTN Executive Committee convened a Patient and Caregiver Advocacy Task Force with a diverse membership representing a variety of stakeholders. The charge to the Task Force was to provide achievable recommendations for incorporating patient input at all steps of clinical trial development from initial concept to dissemination of results. Four focus areas were identified: (1) patient and caregiver input in research portfolio; (2) patient engagement in informed consent, protocol development and trial conduct; (3) communication to patients about trial progress, primary outcomes and secondary analyses; and (4) increased awareness among patients who may be considering BMT or cell therapy about BMT CTN trials. Three specific initiatives were considered as high priority by the Task Force: Fostering patient and caregiver engagement in development of the research portfolio and protocols; Developing communication plans for ongoing studies; and Simplifying the process for informed consent to make it more patient friendly. The BMT CTN has established a patient and caregiver advocacy committee that is tasked with developing concrete steps to incorporate recommendations of the BMT CTN Task Force in its current and future work. The BMT CTN recognizes patient and caregivers are valuable partners whose voice will enhance the conduct of impactful trials in BMT and cell therapy.

Rare lysosomal disease registries: lessons learned over three decades of real-world evidence

Lysosomal storage disorders (LSD) are rare diseases, caused by inherited deficiencies of lysosomal enzymes/transporters, that affect 1 in 7000 to 1 in 8000 newborns. Individuals with LSDs face long diagnostic journeys during which debilitating and life-threatening events can occur. Clinical trials and classical descriptions of LSDs typically focus on common manifestations, which are not representative of the vast phenotypic heterogeneity encountered in real-world experience. Additionally, recognizing that there was a limited understanding of the natural history, disease progression, and real-world clinical outcomes of rare LSDs, a collaborative partnership was pioneered 30 years ago to address these gaps. The Rare Disease Registries (RDR) (for Gaucher, Fabry, Mucopolysaccharidosis type I, and Pompe), represent the largest observational database for these LSDs. Over the past thirty years, data from the RDRs have helped to inform scientific understanding and the development of comprehensive monitoring and treatment guidelines by creating a framework for data collection and establishing a standard of care, with an overarching goal to improve the quality of life of affected patients. Here, we highlight the history, process, and impact of the RDRs, and discuss the lessons learned and future directions.

POS1147 CHALLENGES IN CONDUCTING PRAGMATIC CARE STRATEGY STUDIES IN OSTEOPOROSIS: PATIENT PERCEPTIONS

Background

Large pragmatic osteoporosis studies to improve outcomes are needed. Direct-to-patient studies have highest generalizability but achieving sufficient sample size is difficult; recruitment challenges represent an important consideration given limited participant eligibility and interest. The Fracture Liaison Service (FLS), a team approach to post-fracture care, is a secondary fracture prevention method that has significantly improved outcomes internationally.

Objectives

Our goal was to evaluate the interest, barriers, and lessons learned in recruiting participants for a future trial assessing remote FLS approaches for post-fracture care.

Methods

We used ICD10 fracture codes to identify patients > 50 years of age with a documented hip/pelvis, spine, humerus, or wrist fracture in the previous 1 year. We excluded patients with i) prescriptions for osteoporosis medications (e.g., bisphosphonates, parathyroid hormone analogs, denosumab, romosozumab, raloxifene) in the prior 1 year; ii) an ICD10 code for end-stage renal disease, non-osteoporotic metabolic bone disease, malignant neoplasm, or motor vehicle accident. In December 2021, research assistants reviewed electronic health records (EHR) of potentially eligible patients for evidence of additional serious illness limiting life expectancy to < 1 year or non-ambulatory status prior to fracture. Research assistants called preliminary eligible patients that met inclusion and exclusion criteria and asked them to complete a survey by phone. Interest in a FLS future clinical trial was evaluated using a Likert scale (1=“Definitely would not volunteer”, to 5=“Definitely would volunteer”). We used descriptive statistics to analyze baseline demographic, clinical characteristics, and interest. This pilot was approved by the UAB Institutional Review Board (IRB-300008310-005).

Results

We identified 1,577 patients > 50 years of age with a fracture. After applying exclusion criteria, we identified 869 preliminary eligible patients. Over 3 weeks, we screened the medical records of a random sample of half of the preliminary eligible patient cohort (n=414), of whom we contacted 271 patients determined potentially eligible, and successfully reached 141 (52% of those contacted) by phone. A total of 108 (77% of those reached) persons, mean (SD) age 69.5 (11.5) years, 40% men, 21% Black or non-white Hispanics completed the survey. Among those contacted, 68 (63%, interest rate) said they would be very or highly interested in participating in a future clinical trial evaluating FLS approaches. Among the 40 (37%) people who said they were not sure, unlikely or very unlikely to volunteer the most common reasons cited were “I don’t want to participate in a study” (33%); “I don’t feel well enough to participate” (10%); “I don’t understand what the study is for” (3%). From this pilot, we calculated a refined eligibility/interest rate of 9.1% among those patients preliminarily identified as eligible using administrative data alone.

Conclusion

Based on our pilot, we estimate that approximately 9% of eligible patients with fractures will be interested in enrolling in a future comparative effectiveness study to prevent recurrent fragility fractures. We identified several potential modifiable barriers to clinical trial recruitment. Patient perceptions collected from this pilot will inform enrollment strategies, which can be incorporated early when planning direct-to-patient pragmatic osteoporosis studies to achieve recruitment goals.

Induction of the integrated stress response in the rat cornea

Keratoconus (KC), a progressive, degenerative corneal disease, represents the second leading indication for corneal transplantation globally. We have previously demonstrated that components of the Integrated Stress Response (ISR) are upregulated in human keratoconic donor tissue, and treatment of normal tissue with ISR agonists attenuates collagen production. With no consistently accepted animal models available for translational KC research, we sought to establish an in vivo model based on ISR activation to elucidate its role in the development of the KC phenotype. Four-week-old female SD rats were treated with topical SAL003 formulated as a nanosuspension or vehicle every 48 h for four doses. Animals were subject to monitoring for ocular inflammation and discomfort before being euthanized at 1, 14, or 28 days after treatment was withdrawn. Schirmer's tear test, intraocular pressure, and body weight measurements were obtained at baseline and prior to euthanasia. Globes were subject to routine histopathology, immunohistochemistry for ATF4, and qPCR for Col1a1 expression. ANOVAs and Student's t tests were used to assess statistical significance (α = 0.05). SAL003 treatment did not produce any adverse ocular or systemic phenotype but did result in decreased keratocyte density. Col1a1 transcripts were reduced, corresponding to nuclear ATF4 expression within the axial cornea. In vivo topical treatment with a gel-formulated ISR agonist recapitulates key features of the activated ISR including nuclear ATF4 expression and decreased extracellular matrix (ECM) production. Exogenous ISR agonists may present one approach to establishing a rodent model for keratoconus, a charge essential for future evaluations of pathogenesis and therapeutic interventions.

POS0135 REDUCING IMMUNOGENICITY OF PEGLOTICASE (RECIPE) WITH CONCOMITANT USE OF MYCOPHENOLATE MOFETIL IN PATIENTS WITH REFRACTORY GOUT: A PHASE II RANDOMIZED CONTROLLED TRIAL

Background:

Pegloticase is a recombinant, pegylated uricase, used for treatment of gout patients who fail oral urate lowering therapy (ULT). Its use has been limited due to immunogenicity leading to infusion reactions.1

Objectives:

We evaluated if co-administration of an immunomodulatory agent could prolong the efficacy of pegloticase.

Methods:

Participants were recruited in a Phase II, double-blind, placebo-controlled trial over 18 months and randomized in a 3:1 ratio by site. Inclusion criteria were: a) Age ≥ 18 years who met 2015 ACR/EULAR gout classification criteria and b) chronic refractory gout defined as symptoms inadequately controlled with ULT or contraindications. After a 2-week run-in of mycophenolate mofetil (MMF) 1000 mg twice daily or matching placebo (PBO), they received a combination of pegloticase 8 mg biweekly with MMF or PBO for 12 weeks. Subsequent to this MMF or PBO were discontinued but pegloticase was continued for another 12 weeks. The primary endpoint was proportion of patients who sustained a serum urate (SU) level of ≤ 6 mg/dl at 12 weeks. Secondary endpoints included 24-week durability of SU ≤ 6 mg/dl and rate of adverse events (AEs). Fisher’s exact test and Wilcoxon two-sample test were used for analyses along with Kaplan-Meier estimates and log-rank tests to compare survival curves between groups. Hypothesis tests were two-tailed and p-value (p) < 0.05 indicated statistical significance.

Results:

Of 42 subjects screened, 35 were randomized, and 32 who received at least one dose of pegloticase were included in modified intention to treat analyses. Subjects were predominantly men (88%), mean age of 55.2 years (SD=9.7). Mean duration of gout was 13.4 years (SD=9.0), mean baseline sUA was 9.2 mg/dL (SD=1.6). Tophi were present in 88% and majority were on optimized ULT - 59% on allopurinol and 16% on febuxostat, with 63% reporting > 1 flare in the past year. At baseline both arms (MMF vs. PBO) had similar comorbidities – (82% vs 70%), diabetes mellitus/metabolic syndrome (14% vs 20%), coronary artery disease/peripheral vascular disease (41% vs.70%), BMI>30 (86% vs. 90%) and renal insufficiency (defined as eGFR < 90 mL/min; 73% vs. 70%). At 12 weeks, 19 of 22 (86%) in the MMF arm achieved SU ≤ 6 mg/dl compared to 4 of 10 (40%) in PBO arm (p-value = 0.01). At 24 weeks, the SU was ≤ 6 mg/dl in 68% of MMF arm vs. 30% in PBO (p-value = 0.06), and rates of AEs per month were similar between groups with the PBO arm having more infusion reactions (30% vs. 0%). The MMF arm had higher AEs compared to placebo: musculoskeletal (41% vs. 10%), gastrointestinal (18% vs. 10%), and infections (9% vs. 0%). Figure 1 shows that the percentage of subjects maintaining a sUA < 6 mg/dL at 12 weeks was significantly higher (p=0.02) in the MMF arm, and a significant difference (p=0.03) at 24 weeks indicates sustained benefit from MMF.

Conclusion:

To our knowledge this is the first randomized-controlled proof of concept trial to demonstrate the ability of an immunomodulatory agent in prolonging the efficacy of pegloticase. Short-term concomitant use of MMF therapy with pegloticase was well tolerated and showed a clinically meaningful improvement in the targeted SU ≤6 mg/dL at 12 and 24 weeks. This study suggests an innovative approach to utilize pegloticase therapy in patients with chronic gout.

Addressing Knowledge Gaps in Acute Myeloid Leukemia to Improve Referral for Hematopoietic Cell Transplantation Consultation

BACKGROUND

Outcomes after hematopoietic cell transplantation (HCT) for acute myeloid leukemia (AML) are better when HCT is performed during first complete remission (CR1). This study aimed to identify and address knowledge gaps that affect the timely referral of patients for HCT consultation.

METHODS

A mixed-methods educational needs assessment included a national survey and focus groups consisting of hematologists/oncologists. An educational intervention of 3 webinars addressed identified knowledge gaps.

RESULTS

A total of 150 hematologists/oncologists were recruited for the survey, of whom 20 participated in focus groups. Physicians in practice 0 to 10 years were 4.2 times more likely to refer for HCT consultation in CR1 than those with >10 years in practice (P=.0027). Physicians seeing ≤10 patients with AML in the past year were 3.7 times more likely to refer for HCT consultation in CR1 than those seeing >10 patients (P=.0028). Knowledge gaps included (1) improper classification of molecular/cytogenetic results for risk stratification, (2) lack of understanding that disease stage impacts outcomes, and (3) use of chronologic age alone for referral decision-making. Combined attendance for the webinars was 1,098 clinicians; >74% of participants indicated that they would apply the knowledge they gained in clinical practice. Trends were observed toward improvement in identifying favorable-risk AML, from 48% to 60% (n=85; P=.12); improvement in identifying 2 poor-risk cytogenetic/molecular abnormalities, with the percentage of respondents indicating chromosome 7 deletion increasing from 51% to 70% (n=53; P=.05) and that of respondents indicating TP53 mutation increasing from 42% to 62% (n=62; P=.03); and improvement in identifying which patients with AML aged >60 years were most likely to benefit from HCT based on cytogenetic/molecular features, with the percentage of correct responses increasing from 66% to 81% (n=62; P=.07).

CONCLUSIONS

The webinars met the educational needs of learners and improved knowledge gaps. This study provided novel insights into the learning needs of clinicians who care for patients with AML and a roadmap for future educational interventions.

Information Needs for Treatment Decision-making of Hematopoietic Cell Transplant Patients 65 Years or Older and Caregivers

Hematopoietic cell transplantation (HCT) is a complex and potentially life-threatening treatment option for patients with hematologic malignant and non-malignant diseases. Advances have made HCT a potentially curative treatment option for patients 65 years of age and older (older patients), and patient education resources should be adapted to meet their needs. To better understand the information needs of older patients and their caregivers for HCT treatment decision-making, the National Marrow Donor Program® (NMDP)/Be The Match® conducted a qualitative comprehensive needs assessment. Focus groups, offered in person or by phone, were conducted with older HCT patients and primary caregivers of older HCT patients at three transplant centers in the USA that were selected based on the number of older adults treated and geographic diversity. The one-hour, semi-structured discussions were recorded and transcribed verbatim. The analysis was performed with the NVivo 10 software for identification of conceptual themes. Five telephone and six in person focus groups of patients (n = 35) and caregivers (n = 10) were conducted. Themes that emerged included the following: (1) the need for tailored resources with age-specific recovery expectations; (2) the need for the right amount of information at the right times; and (3) the benefit of peer support. Effective patient education supports learning and treatment decision-making. As HCT increasingly becomes a treatment option for older patients, tailored educational resources are needed. These focus group results can inform and guide the development of new educational resources for older adults with hematologic diseases considering and planning for HCT.

Glancing-angle-deposited silica films for ultraviolet wave plates

Birefringent silica films are formed by glancing-angle deposition to fabricate quarter- and half-wave plates at a wavelength of 351 nm. A multilayer design is implemented to achieve low-loss transmittance with a high 351-nm laser-induced damage threshold.

Supersonic plasma turbulence in the laboratory

The properties of supersonic, compressible plasma turbulence determine the behavior of many terrestrial and astrophysical systems. In the interstellar medium and molecular clouds, compressible turbulence plays a vital role in star formation and the evolution of our galaxy. Observations of the density and velocity power spectra in the Orion B and Perseus molecular clouds show large deviations from those predicted for incompressible turbulence. Hydrodynamic simulations attribute this to the high Mach number in the interstellar medium (ISM), although the exact details of this dependence are not well understood. Here we investigate experimentally the statistical behavior of boundary-free supersonic turbulence created by the collision of two laser-driven high-velocity turbulent plasma jets. The Mach number dependence of the slopes of the density and velocity power spectra agree with astrophysical observations, and supports the notion that the turbulence transitions from being Kolmogorov-like at low Mach number to being more Burgers-like at higher Mach numbers.

Prevention of Infection: A Systematic Review of Evidence-Based Practice Interventions for Management in Patients With Cancer

BACKGROUND

Cancer-related infections lead to increases in mortality, antibiotic use, and hospital stays. Other adverse outcomes include dose delays and reductions, which can result in suboptimal treatment outcomes.

OBJECTIVES

Effective implementation of risk assessment and evidence-based interventions for the prevention and treatment of infection are essential to improve care and reduce costs related to infections in patients with cancer receiving immunosuppressive therapy.

METHODS

The Oncology Nursing Society (ONS) Putting Evidence Into Practice (PEP) prevention of infection resource have been developed and updated to identify and disseminate the best available scientific evidence.

FINDINGS

Pharmacologic and nonpharmacologic interventions were evaluated, resulting in recommended for practice rating for catheter care bundles, antimicrobial prophylaxis, vaccination for specific populations, and implementation of contact precautions for resistant organisms.

A Conceptual Framework and Key Research Questions in Educational Needs of Blood and Marrow Transplantation Patients, Caregivers, and Families

Patient, caregiver, and family education and support was 1 of 6 key areas of interest identified by the National Marrow Donor Program/Be The Match 2-year project to prioritize patient-centered outcomes research (PCOR) goals for the blood and marrow transplantation (BMT) community. PCOR focuses on research to help patients and their caregivers make informed decisions about health care. Therefore, each area of interest was assigned to a working group with broad representation, including patients, caregivers, and clinicians. Each working group was charged with identifying gaps in knowledge and making priority recommendations for critical research to fill those gaps. The report from this working group presents a conceptual framework to address gaps in knowledge regarding patient and caregiver education in BMT and recommendations for priority research questions on this topic.

Tailoring a Survivorship Care Plan: Patient and Provider Preferences for Recipients of Hematopoietic Cell Transplantation

This study aimed to develop a survivorship care plan (SCP) that can be individualized to facilitate long-term follow-up care of hematopoietic cell transplantation (HCT) survivors. A sample SCP was developed that included 2 documents: a treatment summary and preventive care recommendations that combined data on treatment exposures routinely submitted by HCT centers to the Center for International Blood and Marrow Transplant Research (CIBMTR) with long-term follow-up guidelines. Focus groups were conducted by phone to characterize the critical patient-centered elements of the SCP. Focus group eligibility criteria included (1) adult patients >1 year post-HCT and their caregivers (3 groups; n = 22), (2) HCT physicians and advanced practice providers (APPs) (2 groups; n = 14), (3) HCT nurses and social workers (4 groups; n = 17), and (4) community health care professionals (3 groups; n = 24). Transcripts were analyzed for saturation of key themes using NVivo 10 software. Patients and caregivers suggested combining the treatment summary and care guidelines into a single document. They also requested sections on sexual and emotional health and the immune system. Providers wanted the treatment summary to focus only on what they absolutely must know. Themes were similar across healthcare professionals, although screening for psychosocial issues was emphasized more by the nurses and social workers. All preferred to receive the SCP electronically; however, hardcopy was considered necessary for some patients. All felt that the SCP would facilitate appropriate post-HCT care. This study highlights the need for an SCP instrument to facilitate HCT survivorship care. Furthermore, it demonstrates the feasibility and value of engaging HCT recipients, caregivers, and providers in developing an SCP. Their feedback was incorporated into a final SCP that was subsequently tested in a randomized trial.

Laboratory evidence of dynamo amplification of magnetic fields in a turbulent plasma

Magnetic fields are ubiquitous in the Universe. The energy density of these fields is typically comparable to the energy density of the fluid motions of the plasma in which they are embedded, making magnetic fields essential players in the dynamics of the luminous matter. The standard theoretical model for the origin of these strong magnetic fields is through the amplification of tiny seed fields via turbulent dynamo to the level consistent with current observations. However, experimental demonstration of the turbulent dynamo mechanism has remained elusive, since it requires plasma conditions that are extremely hard to re-create in terrestrial laboratories. Here we demonstrate, using laser-produced colliding plasma flows, that turbulence is indeed capable of rapidly amplifying seed fields to near equipartition with the turbulent fluid motions. These results support the notion that turbulent dynamo is a viable mechanism responsible for the observed present-day magnetization.

Applying Health Literacy Principles: Strategies and Tools to Develop Easy-to-Read Patient Education Resources

Health literacy is an important construct in health care that affects patient outcomes and overall health. The impact of limited health literacy in cancer care is wide, and it can affect patients' ability to make treatment decisions, follow directions on a prescription label, or adhere to neutropenic precautions. This article describes strategies and tools for nurses to use when developing written patient education resources in their daily practice.

Health promotion through sport: international sport federations’ priorities, actions and opportunities

Objective

To identify areas of priority and activity for international sportsfederations (IFs) with respect to athlete health and safety, and global health. Results serve to direct the work of the Association of Summer Olympic IF Medical and Scientific Consultative Group, the International Olympic Committee and to influence IFs’ planning and priorities.

Methods

The 28 IFs participating in the Summer Olympic Games (2016) were asked to rank the relative importance of 11 health-related topics and to report their activities or research initiatives on 27 identified topics using an electronic survey. A comparison with a similar survey (2012) was made.

Results

The response rate was 100%. In general, the ‘fight against doping’ had the highest priority followed by ‘image as a safe sport’. The topics with the lowest importance ratings were ‘increasing the number of elite athletes’, and ‘health of the general population’. Despite ranking ‘health of your athletes,’ as a top priority, IFs are not addressing all aspects of athlete health. In comparison with 2012, there was a significant decrease in priority for IFs is ‘health of the general population’.

Conclusion

Despite the widespread knowledge of the importance of the promotion of physical activity (sport) on global health, the decreasing priority and programming of the IFs on physical activity promotion is concerning. Although IFs have prioritised the protection of the health of elite athletes, there are gaps in programming demonstrating that IFs are missing important areas of athlete health. Improving recreational athlete health programming could also benefit population health as well as improve IF fan base and sport participation.

Feasibility of training nurses in motivational interviewing to improve patient experience in mental health inpatient rehabilitation: a pilot study

WHAT IS KNOWN ON THE SUBJECT?: Recently, concerns have been raised about how well United Kingdom National Health Service nurses care for their patients and their level of compassion. Motivational interviewing (MI) is an established approach to helping people make positive behaviour changes, through directive, person-centred counselling within a collaborative relationship between clinician and recipient. Based on evidence that MI may influence nursing practice positively, an investigation into the feasibility of training nurses on mental health inpatient rehabilitation wards ('rehabilitation') in MI to improve patient experience was reported. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This pilot study demonstrates that training rehabilitation nurses in MI is feasible and provides preliminary evidence suggesting that a larger study to examine efficacy is warranted, including a calculation of sample size required to draw robust statistical conclusions. Nurses evaluated the training as highly relevant to their work. Patients responded well to interviews and focus groups with support from experts-by-experience; they were generally fairly satisfied with the rehabilitation ward and slight improvements in their experience were found following MI training for nurses but not at 6-month follow-up. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Rehabilitation nurses may face conflicting demands between ensuring patients with severe difficulties meet their basic needs and working with them to develop greater independence. Qualitative findings question whether nurse-patient interactions are fully valued as nursing interventions in inpatient rehabilitation. Learning MI might be a useful way of helping nurses think in detail about their interactions with patients and how to improve communications with their patients. The principles of MI should be incorporated into pre-registration training.

ABSTRACT

Introduction There is limited research addressing the experiences of patients in inpatient rehabilitation (rehabilitation), who often spend long periods in hospital, and the nursing approaches utilized. Aim Based on evidence that motivational interviewing (MI) may improve nursing practice, this was a pilot study evaluating the feasibility of training rehabilitation nurses in MI and measuring patient experience. Method Nurses underwent training and supervision focusing on MI spirit. Quantitative and qualitative measures were taken pretraining, 2 months post-training and 8 months post-training. Expert-by-experience research assistants facilitated patients' participation in the study. Results This study showed that training rehabilitation nurses in MI was feasible and relevant to their work. Patients participated in interviews and focus groups with support and potential improvements that require further empirical investigation in patient experience were found following the MI training. Discussion This pilot study establishes the feasibility of a larger study addressing efficacy. Tentative qualitative findings question whether interactions between nurses and patients are valued in rehabilitation and support MI as a promising skill set for rehabilitation nurses. Implications for practice Bringing MI into inpatient rehabilitation provoked reflection on nursing practice. Dilemmas for nurses about balancing safety with promoting autonomy and communicating constructively with patients emerged as important.

From 'Virgin Births' to 'Octomom': Representations of Single Motherhood via Sperm Donation in the UK News

The use of sperm donation by single women has provoked public, professional and political debate. Newspapers serve as a critical means of both broadcasting this debate and effecting a representation of this user group within the public sphere. This study uses the theory of social representations to examine how single motherhood by sperm donation has been represented in the UK news over time. The study sampled news coverage on this topic in eight British newspapers during three 4-year periods between the years 1988 and 2012. The dataset of news reports (n = 406) was analysed using a qualitative approach. Findings indicated that UK media reports of single women using donor sperm are underpinned by conventional categories of the 'personal', the 'traditional' and the 'natural' that when paired with their corollaries produce a representation of this user group as the social 'other'. The amount of coverage on this topic over time was found to vary according to the political orientation of different media sources. Using key concepts from social representations theory, this article discusses the relationship between themata and anchoring in the maintenance of representations of the social 'other' in mass mediated communication. Findings are explained in relation to theoretical conceptions of the mass media and its position within the public sphere. It is argued that the use of personal narratives in news reports of single mothers by sperm donation may have significant implications for public understandings of this social group. © 2016 The Authors.

Disease Risk Analysis and Post-Release Health Surveillance for a Reintroduction Programme: the Pool Frog Pelophylax lessonae

There are risks from disease in undertaking wild animal reintroduction programmes. Methods of disease risk analysis have been advocated to assess and mitigate these risks, and post-release health and disease surveillance can be used to assess the effectiveness of the disease risk analysis, but results for a reintroduction programme have not to date been recorded. We carried out a disease risk analysis for the reintroduction of pool frogs (Pelophylax lessonae) to England, using information gained from the literature and from diagnostic testing of Swedish pool frogs and native amphibians. Ranavirus and Batrachochytrium dendrobatidis were considered high-risk disease threats for pool frogs at the destination site. Quarantine was used to manage risks from disease due to these two agents at the reintroduction site: the quarantine barrier surrounded the reintroduced pool frogs. Post-release health surveillance was carried out through regular health examinations of amphibians in the field at the reintroduction site and collection and examination of dead amphibians. No significant health or disease problems were detected, but the detection rate of dead amphibians was very low. Methods to detect a higher proportion of dead reintroduced animals and closely related species are required to better assess the effects of reintroduction on health and disease.

In vivo PET imaging of the neuroinflammatory response in rat spinal cord injury using the TSPO tracer [(18)F]GE-180 and effect of docosahexaenoic acid

Purpose

Traumatic spinal cord injury (SCI) is a devastating condition which affects millions of people worldwide causing major disability and substantial socioeconomic burden. There are currently no effective treatments. Modulating the neuroinflammatory (NI) response after SCI has evolved as a major therapeutic strategy. PET can be used to detect the upregulation of the 18-kDa translocator protein (TSPO), a hallmark of activated microglia in the CNS. We investigated whether PET imaging using the novel TSPO tracer [¹⁸F]GE-180 can be used as a clinically relevant biomarker for NI in a contusion SCI rat model, and we present data on the modulation of NI by the lipid docosahexaenoic acid (DHA).

Methods

A total of 22 adult male Wistar rats were subjected to controlled spinal cord contusion at the T10 spinal cord level. Six non-injured and ten T10 laminectomy only (LAM) animals were used as controls. A subset of six SCI animals were treated with a single intravenous dose of 250 nmol/kg DHA (SCI-DHA group) 30 min after injury; a saline-injected group of six animals was used as an injection control. PET and CT imaging was carried out 7 days after injury using the [¹⁸F]GE-180 radiotracer. After imaging, the animals were killed and the spinal cord dissected out for biodistribution and autoradiography studies. In vivo data were correlated with ex vivo immunohistochemistry for TSPO.

Results

In vivo dynamic PET imaging revealed an increase in tracer uptake in the spinal cord of the SCI animals compared with the non-injured and LAM animals from 35 min after injection (P < 0.0001; SCI vs. LAM vs. non-injured). Biodistribution and autoradiography studies confirmed the high affinity and specific [¹⁸F]GE-180 binding in the injured spinal cord compared with the binding in the control groups. Furthermore, they also showed decreased tracer uptake in the T10 SCI area in relation to the non-injured remainder of the spinal cord in the SCI-DHA group compared with the SCI-saline group (P < 0.05), supporting a NI modulatory effect of DHA. Immunohistochemistry showed a high level of TSPO expression (38 %) at the T10 injury site in SCI animals compared with that in the non-injured animals (6 %).

Conclusion

[¹⁸F]GE-180 PET imaging can reveal areas of increased TSPO expression that can be visualized and quantified in vivo after SCI, offering a minimally invasive approach to the monitoring of NI in SCI models and providing a translatable clinical readout for the testing of new therapies.

Increasing the frequency of physical activity very brief advice for cancer patients. Development of an intervention using the behaviour change wheel

BACKGROUND

Being physically active has multiple benefits for cancer patients. Despite this only 23% are active to the national recommendations and 31% are completely inactive. A cancer diagnosis offers a teachable moment in which patients might be more receptive to lifestyle changes. Nurses are well placed to offer physical activity advice, however, only 9% of UK nurses involved in cancer care talk to all cancer patients about physical activity. A change in the behaviour of nurses is needed to routinely deliver physical activity advice to cancer patients. As recommended by the Medical Research Council, behavioural change interventions should be evidenced-based and use a relevant and coherent theoretical framework to stand the best chance of success.

OBJECTIVE

This paper presents a case study on the development of an intervention to improve the frequency of delivery of very brief advice (VBA) on physical activity by nurses to cancer patients, using the Behaviour Change Wheel (BCW).

METHOD

The eight composite steps outlined by the BCW guided the intervention development process. An iterative approach was taken involving key stakeholders (n = 45), with four iterations completed in total. This was not defined a priori but emerged during the development process.

RESULTS

A 60 min training intervention, delivered in either a face-to-face or online setting, with follow-up at eight weeks, was designed to improve the capability, opportunity and motivation of nurses to deliver VBA on physical activity to people living with cancer. This intervention incorporates seven behaviour change techniques of goal setting coupled with commitment; instructions on how to perform the behaviour; salience of the consequences of delivering VBA; a demonstration on how to give VBA, all delivered via a credible source with objects added to the environment to support behavioural change.

CONCLUSION

The BCW is a time consuming process, however, it provides a useful and comprehensive framework for intervention development and greater control over intervention replication and evaluation.

A Mayan founder mutation is a common cause of deafness in Guatemala

Over 5% of the world's population has varying degrees of hearing loss. Mutations in GJB2 are the most common cause of autosomal recessive non-syndromic hearing loss (ARNHL) in many populations. The frequency and type of mutations are influenced by ethnicity. Guatemala is a multi-ethnic country with four major populations: Maya, Ladino, Xinca, and Garifuna. To determine the mutation profile of GJB2 in a ARNHL population from Guatemala, we sequenced both exons of GJB2 in 133 unrelated families. A total of six pathogenic variants were detected. The most frequent pathogenic variant is c.131G>A (p.Trp44*) detected in 21 of 266 alleles. We show that c.131G>A is associated with a conserved haplotype in Guatemala suggesting a single founder. The majority of Mayan population lives in the west region of the country from where all c.131G>A carriers originated. Further analysis of genome-wide variation of individuals carrying the c.131G>A mutation compared with those of Native American, European, and African populations shows a close match with the Mayan population.

Open-access optical microcavities for lab-on-a-chip refractive index sensing

Open-access optical microcavities provide a novel approach to label-free lab-on-a-chip optofluidic sensing. They offer direct access to a highly confined electromagnetic field, and yield a femtoliter detection volume. This article describes the characteristics of these devices for refractive index sensing. We show that most of the ambient noise can be removed from the refractive index data by simultaneous tracking of resonances across an array of cavities. A sensitivity of 3.5 × 10(-4) RIU is demonstrated which corresponds to detecting the refractive index change caused by the presence of 500,000 glucose molecules in aqueous solution.

Factors associated with birth weight inequalities in Jordan

BACKGROUND

Birth weight is a good indicator of mothers' and neonates' nutritional status, and it contributes to the newborn baby's survival, health, growth and development.

AIM

This study identified social factors associated with differences in the mean birth weight of newborn babies in Jordan.

METHODS

This retrospective study analysed medical records to determine possible risk factors associated with differences in newborn BW in the Irbid governorate of Jordan. All full-term singleton births during the year 2010 were reviewed. Abstracted data included mother's age, educational level, and monthly family income. Newborn information included birth weight, gender and birth order.

RESULTS

A total of 5414 full-term singleton births were included. Of these, 15.1% were low birth weight, 73.6% were normal birth weight, and 11.3% were high birth weight. Bivariate analysis of variance revealed that low mean birth weight was associated with female gender, first-born babies, higher maternal age (>35 years), lower educational level and lower income (<500 JD). Multivariate analysis of variance revealed that mean birth weight was lower in female infants, first-born infants, infants of less educated mothers, higher age and low monthly income.

LIMITATIONS

The findings can be generalized to full-term singleton pregnancies in countries who share similar cultural and traditional values.

CONCLUSION

Education of mothers is a modifiable variable that can positively influence birth weight, particularly in the case of female and first-born infants.

IMPLICATION FOR NURSING AND HEALTH POLICY

The findings inform our understanding of some social factors affecting birth weights of neonates in Jordan and development of effective public health interventions that could reduce the adverse effects of such factors on newborn birth weight. Preconception and antenatal care is also important for early detection of such possible risk and targeting mothers who require early interventions and support.

MRI-based abnormalities in young adults at risk of adverse bone health due to childhood-onset metabolic & endocrine conditions

OBJECTIVE

Traditional methods of bone densitometry may not provide a comprehensive assessment of bone health. We aimed to assess bone micro-architecture and bone marrow adiposity (BMA) by MRI in adults with osteogenesis imperfecta (OI) and endocrinopathy including GH deficiency and/or hypogonadism.

MEASUREMENTS

High-resolution micro-MRI images were acquired at the tibia using 3T MRI to calculate parameters of bone micro-architecture in seven adults with OI and 10 adults with endocrinopathies. MR Spectroscopy was performed in participants to calculate vertebral BMA, which was expressed as percentage fat fraction (%FF). Lumbar spine DXA was performed to assess bone mineral density. The MRI data were compared with a group of 22 healthy adults who were divided into two age-matched control groups.

RESULTS

Intra-operator repeatability was high, with an average CoV of 1% for micro-MRI and 2·5% for MRS. The ratio of apparent bone volume to total volume (appBV/TV) in the endocrinopathy and OI groups was lower than in age-matched control groups (P = 0·003 and P = 0·008 respectively). A weak association between DXA BMD and appBV/TV was also observed (r = 0·5, P = 0·045). %FF was higher in the endocrinopathy group than in the age-matched control group (P = 0·005), but no difference in %FF was observed between the OI group and their age-matched control group (P = 0·26).

CONCLUSIONS

MRI provides valuable detailed information on the micro-architecture and adiposity of bones and is capable of showing clear differences in bone parameters in a range of clinical conditions associated with abnormal bone health.
