The Patient's perspective: A review of the results from a radiotherapy patient experience survey in the North-West of England. Radiography (Lond) 2023; 29 Suppl 1:S59-S67. [PMID: 36934026 DOI: 10.1016/j.radi.2023.02.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 02/17/2023] [Accepted: 02/21/2023] [Indexed: 03/19/2023]
Abstract
INTRODUCTION A patient experience survey was undertaken for patients completing radiotherapy at the three Northwest of England Radiotherapy Providers. METHODS A previously reported National Radiotherapy Patient Experience Survey was adapted and undertaken in the Northwest of England. Quantitative data was analysed to establish trends. Frequency distribution was applied to appraise the number of participants selecting each of the pre-determined responses. Thematic analysis of free text responses was conducted. RESULTS The questionnaire received 653 responses from the 3 providers across seven departments. Thematic analysis revealed 3 themes; logistics, information and operational. CONCLUSION The results indicate that the majority of patients are satisfied with their treatment and care. Patients' responses indicate areas for improvements. Expectancy theory states that an individual's satisfaction is related to the difference between expected service and the service received. Consequently, when reviewing services and developing improvement it is important to understand patients' expectations. This regional survey starts to capture what people receiving radiotherapy expect from the service and the professionals delivering their treatment. IMPLICATIONS FOR PRACTICE This survey responses make a case for reviewing the information provision pre and post radiotherapy. This includes clarifying the understanding of consent for treatment including the intended benefits and potential late effects. There is an argument to offer information sessions prior to radiotherapy to achieve more relaxed and informed patients. A recommendation from this work is for the radiotherapy community undertake a national radiotherapy patient experience survey, facilitated via the 11 Radiotherapy ODNs. A national radiotherapy survey has multiple benefits to inform improvements in practice. This includes benchmarking services against national averages. This approach is aligned with the principles of the service specification in terms of reducing variation and increasing quality.

Abstract
Realizing quantum speedup for practically relevant, computationally hard problems is a central challenge in quantum information science. Using Rydberg atom arrays with up to 289 qubits in two spatial dimensions, we experimentally investigate quantum algorithms for solving the Maximum Independent Set problem. We use a hardware-efficient encoding associated with Rydberg blockade, realize closed-loop optimization to test several variational algorithms, and subsequently apply them to systematically explore a class of graphs with programmable connectivity. We find the problem hardness is controlled by the solution degeneracy and number of local minima, and experimentally benchmark the quantum algorithm's performance against classical simulated annealing. On the hardest graphs, we observe a superlinear quantum speedup in finding exact solutions in the deep circuit regime and analyze its origins.

Abstract
Health and human services workers (HHS; e.g., child welfare, physical and mental healthcare) engage with clients facing heightened vulnerability during the COVID-19 pandemic. Under typical circumstances, HHS workers face a host of challenges in carrying out their job responsibilities such as high caseloads and burnout, and now navigate new challenges such as social distancing protocols and protecting their own health and that of their families and clients. This study explored the experiences of 531 HHS workers in Florida to understand well-being impacts of COVID-19 on the HHS workforce. Using a social ecological framework, we analyzed open-ended responses from HHS workers to better understand the multi-level and frequently intertwined impacts of COVID-19. Participants reported numerous proximal factors (i.e., intrapersonal, interpersonal, organizational) impacting their well-being but fewer distal factors (i.e., community, public policy). Agencies should work to understand the intersecting vulnerabilities of their workers and implement safety protocols to preserve workers' well-being.

Implications of possible interpretations of 'greenhouse gas balance' in the Paris Agreement. PHILOSOPHICAL TRANSACTIONS. SERIES A, MATHEMATICAL, PHYSICAL, AND ENGINEERING SCIENCES 2018; 376:20160445.

Abstract
The main goal of the Paris Agreement as stated in Article 2 is 'holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C'. Article 4 points to this long-term goal and the need to achieve 'balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases'. This statement on 'greenhouse gas balance' is subject to interpretation, and clarifications are needed to make it operational for national and international climate policies. We study possible interpretations from a scientific perspective and analyse their climatic implications. We clarify how the implications for individual gases depend on the metrics used to relate them. We show that the way in which balance is interpreted, achieved and maintained influences temperature outcomes. Achieving and maintaining net-zero CO2-equivalent emissions conventionally calculated using GWP100 (100-year global warming potential) and including substantial positive contributions from short-lived climate-forcing agents such as methane would result in a sustained decline in global temperature. A modified approach to the use of GWP100 (that equates constant emissions of short-lived climate forcers with zero sustained emission of CO2) results in global temperatures remaining approximately constant once net-zero CO2-equivalent emissions are achieved and maintained. Our paper provides policymakers with an overview of issues and choices that are important to determine which approach is most appropriate in the context of the Paris Agreement.This article is part of the theme issue 'The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.

Constraints on oceanic methane emissions west of Svalbard from atmospheric in situ measurements and Lagrangian transport modeling. JOURNAL OF GEOPHYSICAL RESEARCH. ATMOSPHERES : JGR 2016; 121:14188-14200.

Abstract
Methane stored in seabed reservoirs such as methane hydrates can reach the atmosphere in the form of bubbles or dissolved in water. Hydrates could destabilize with rising temperature further increasing greenhouse gas emissions in a warming climate. To assess the impact of oceanic emissions from the area west of Svalbard, where methane hydrates are abundant, we used measurements collected with a research aircraft (Facility for Airborne Atmospheric Measurements) and a ship (Helmer Hansen) during the Summer 2014 and for Zeppelin Observatory for the full year. We present a model-supported analysis of the atmospheric CH4 mixing ratios measured by the different platforms. To address uncertainty about where CH4 emissions actually occur, we explored three scenarios: areas with known seeps, a hydrate stability model, and an ocean depth criterion. We then used a budget analysis and a Lagrangian particle dispersion model to compare measurements taken upwind and downwind of the potential CH4 emission areas. We found small differences between the CH4 mixing ratios measured upwind and downwind of the potential emission areas during the campaign. By taking into account measurement and sampling uncertainties and by determining the sensitivity of the measured mixing ratios to potential oceanic emissions, we provide upper limits for the CH4 fluxes. The CH4 flux during the campaign was small, with an upper limit of 2.5 nmol m-2 s-1 in the stability model scenario. The Zeppelin Observatory data for 2014 suggest CH4 fluxes from the Svalbard continental platform below 0.2 Tg yr-1. All estimates are in the lower range of values previously reported.

Measurements of δ 13C in CH 4 and using particle dispersion modeling to characterize sources of Arctic methane within an air mass. JOURNAL OF GEOPHYSICAL RESEARCH.

Abstract
A stratified air mass enriched in methane (CH4) was sampled at ~600 m to ~2000 m altitude, between the north coast of Norway and Svalbard as part of the Methane in the Arctic: Measurements and Modelling campaign on board the UK's BAe-146-301 Atmospheric Research Aircraft. The approach used here, which combines interpretation of multiple tracers with transport modeling, enables better understanding of the emission sources that contribute to the background mixing ratios of CH4 in the Arctic. Importantly, it allows constraints to be placed on the location and isotopic bulk signature of the emission source(s). Measurements of δ13C in CH4 in whole air samples taken while traversing the air mass identified that the source(s) had a strongly depleted bulk δ13C CH4 isotopic signature of -70 (±2.1)‰. Combined Numerical Atmospheric-dispersion Modeling Environment and inventory analysis indicates that the air mass was recently in the planetary boundary layer over northwest Russia and the Barents Sea, with the likely dominant source of methane being from wetlands in that region.

Abstract
Abstract Two aspects of the family in relation to fertility in developing countries are discussed: set stratification within the family and extended family networks. As both these are central to J. C. Caldwell's theory of fertility transition, the paper is structured as a critique of his position. Drawing on examples and data from Asia, it is argued that the causal significance of sex stratification for fertility lies in the economic risks it imposes on women, deriving from their dependence on men, rather than, as Caldwell suggests, in the disproportionate gain that men derive from their dominant position within families. While Caldwell and others associate strong extended family networks of mutual obligation and support with persistent high fertility, it is argued here that such systems should, instead, facilitate fertility decline. Close-knit and strong kin networks can be viewed as alternatives to children as sources of insurance, and may facilitate fertility decline by preventing children from becoming the focal point of parental concerns for security.

Abstract
xBiFeO(3)-(1-x)PbTiO(3) single crystals were grown via a flux method for a range of compositions. Presented here is a study of the domain configuration in the 0.5BiFeO(3)-0.5PbTiO(3) composition using electron backscatter diffraction to demonstrate the ability of the technique to map ferroelastic domain structures at the micron and submicron scale. The micron-scale domains exhibit an angle of approximately 85 degrees between each variant, indicative of a ferroelastic domain wall in a tetragonal system with a spontaneous strain, c/a - 1 of 0.10, in excellent agreement with the lattice parameters derived from x-ray diffraction. Contrast seen in forescatter images is attributed to variations in the direction of the electrical polarization vector, providing images of ferroelectric domain patterns.

Abstract
AIMS Age-related macular degeneration (AMD) is considered a complex genetic disease, although the genetic influences are not yet fully understood. Genetic analysis is hampered by the late onset of disease and the difficulty in obtaining multigenerational families. To investigate this problem further we studied our population of early onset drusen cases. The Arg345Trp mutation on exon 10 of the EGF-containing fibulin-like extracellular matrix protein 1 (EFEMP1) gene causes two clinical phenotypes of early onset drusen (Doyne honeycomb retinal dystrophy and Malattia Leventinese), yet does not appear to be involved in other early onset drusen phenotypes or typical AMD. We wished to ascertain the involvement of the EFEMP1 gene in our population of sporadic and familial subjects presenting with early onset drusen and their affected relatives. METHODS Individuals presenting with drusen/end-stage maculopathy at 60 years or under were identified from retinal clinics in Melbourne. All available first- and second-degree relatives were also examined. In all, 116 ethnically matched controls were collected from the same community for comparison. RESULTS Single stranded conformational polymorphism (SSCP) analysis and subsequent sequencing revealed four previously described and three novel sequence variations. Most occurred at similar frequencies in the case and control populations and were not thought to be disease associated. CONCLUSION The term early onset drusen encompasses a wide range of phenotypes and our findings indicate that it is likely that more than one gene is involved in its causation. It is essential that these clinical phenotypes are well described and categorised to allow greater possibility of success in the search for other disease genes.

Abstract
In order to assess the influence of the vertebral heart scale (VHS) on the accuracy of the radiographic diagnosis of cardiac disease, thoracic radiographs of 50 dogs with proven cardiac disease, 26 with other thoracic diseases, and 50 with no clinical signs of cardiovascular or respiratory disease were mixed and examined by three independent, blinded observers chosen to represent a range of radiographic abilities. They first examined all the radiographs without making measurements of VHS and made a diagnosis. They then re-examined the radiographs, and measured VHS on both lateral and dorsoventral or ventrodorsal radiographs before again recording a diagnosis without reference to their original diagnoses. For all the observers, the dogs with cardiac disease had a higher mean VHS than the normal dogs. A VHS over 10.7 on the lateral radiograph was a moderately accurate sign of cardiac disease. The observers' accuracy of diagnosis did not change significantly as a result of using VHS as an adjunct to a subjective assessment of the radiographs.

Abstract
There are many rating instruments designed to assess symptoms of agitation in patients with dementia. Most scales require that raters assess multiple specific behaviors over several days, limiting the use of such scales to clinical staff who have direct contact with patients but do not have the time to complete a comprehensive assessment following each period of observation. Also, scales that assess behavior over several days must rely on "secondhand" information describing behaviors not directly observed by the rater. The Pittsburgh Agitation Scale (PAS) is an easy-to-use instrument, based on direct observations of the patient, that was developed to monitor the severity of agitation associated with dementia. Interrater reliability and measures of validity have been established with clinical staff on a busy psychogeriatric inpatient unit and with research personnel in a nursing home setting.

Abstract
Neuropeptide Y (NPY) coexists with noradrenaline in postganglionic sympathetic neurons and with noradrenaline and adrenaline in the central nervous system. The possibility that NPY is released into the circulation during activation of the sympathoadrenal system was investigated in ten moderately hypertensive volunteers using three different stimuli. In healthy moderately hypertensive volunteers cold pressor test, head up tilt and graded bicycle exercise resulted in increased blood pressure, heart rate and plasma catecholamine concentrations. While there was a trend for plasma NPY-like immunoreactivity (NPY-LI) to increase during cold pressor test and head up tilt, NPY-LI concentration only increased significantly during bicycle exercise, the stimulus of greatest duration. These results suggest that plasma NPY-LI can be released into the circulation on sympathoadrenal activation in moderately hypertensive subjects and demonstrate that the pattern of release is similar to that previously observed in normotensive subjects.

Abstract
Plasma concentrations of immunoreactive atrial natriuretic polypeptide were raised in 22 of 23 patients with paroxysmal supraventricular tachycardia and in all seven patients with atrial flutter. Plasma concentrations of atrial natriuretic polypeptide rose soon after the onset of supraventricular tachycardia. A sample taken 30 minutes after reversion to sinus rhythm (pharmacological or non-pharmacological) showed a significant fall in 19 of the 23 patients with paroxysmal supraventricular tachycardia and all seven patients with atrial flutter. Because atrial natriuretic polypeptide has powerful natriuretic and diuretic properties, an increase may contribute considerably to the polyuria that is often associated with episodes of supraventricular tachycardia.

Abstract
1. Plasma concentrations of atrial natriuretic peptide (ANP) and antidiuretic hormone (ADH) were measured in conscious stroke-prone spontaneously hypertensive (SPR), spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) rats before and after acute volume expansion or haemorrhage. 2. Plasma ANP concentration was reduced to one-third of resting values 30 min after a 1.5% haemorrhage (1.5 ml of blood per 100 g bodyweight). Plasma ADH concentration rose immediately 50-fold on haemorrhage and remained elevated at 30 min. 3. Plasma ANP concentration increased 2.5-fold relative to resting values 1 min after infusion of 2.0 ml per 100 g 5% dextrose; after 10 min plasma ANP remained elevated. Plasma ADH concentration tended to fall on volume expansion although no significant decrease was observed. 4. There was no difference in the basal levels of ANP and ADH, or in the changes produced by alterations in blood volume, in hypertensive SPR and SHR compared with normotensive WKY. 5. Thus, plasma ANP concentrations moved in opposite directions in response to two physiological stimuli: volume expansion and haemorrhage. Reciprocal changes were observed in plasma ADH.

Abstract
We have used a sensitive direct radioimmunoassay to study the effects of exercise on plasma atrial natriuretic peptide (ANP) concentrations in man. Plasma ANP concentration increased three-fold in sixteen patients undergoing bicycle ergometer electrocardiographic tests for the investigation of chest pain. Resting ANP concentrations were higher in those patients in whom there was more evidence of heart disease, such as a positive exercise test, treatment with a beta blocker or history of myocardial infarction, although exercise resulted in increased ANP in both groups. We also confirm the increased plasma ANP concentration observed in patients with congestive cardiac failure and renal failure. In nine patients with renal failure routine haemodialysis was accompanied by a 30 per cent reduction in plasma ANP concentration. Plasma ANP concentrations were similar in treated hypertensive patients, untreated borderline hypertensive patients and normotensive subjects.

Abstract
Electrolytic lesions of the A1 noradrenaline cells in the caudal ventrolateral medulla cause transient hypertension and bradycardia in the conscious rat, as previously described in the rabbit. The lesions produced 100-fold increases in plasma arginine vasopressin, 40-fold increases in plasma adrenaline and fourfold increases in plasma noradrenaline levels. Absence of circulating vasopressin [homozygous diabetes insipidus rats (DI)] or circulating adrenaline (adrenalectomized rats) did not affect A1 hypertension, but sympathectomy with systemic 6-hydroxydopamine (6-OHDA) significantly attenuated A1 hypertension. A factorial experiment was performed to assess the relative contributions of these three peripheral effector mechanisms in a quantitative manner, with combined deficiencies of any two or of all three of these effector systems. Results suggest A1 hypertension in the rat to be primarily mediated through increased sympatho-adrenal activity. The largest component of hypertension (66%) results from increased sympathetic vasoconstrictor nerve activity, and a smaller part (34%) reflects the action of circulating adrenaline. Increases in vasopressin levels do not contribute to A1 hypertension, although vasopressin makes a major contribution to A1 lesion bradycardia.
