Reporting radiographers within the European Federation of Radiographer Society (EFRS) member countries - motivation for becoming a reporting radiographer.

INTRODUCTION: Radiographer-led reporting originated in the United Kingdom as a strategy to reduce reporting backlog and time taken to report images. The effectiveness of reporting radiographers has been demonstrated, but their motivational factors have not been thoroughly explored. This survey aims to understand the incentives for radiographers to pursue postgraduate education in reporting radiography across Europe. METHODS: An online survey was conducted, collecting data across a range of topics such as demographic information, professional role, and job satisfaction. Questions assessing the influence of motivational factors on the decision to become a reporting radiographer are presented in this study. Descriptive statistics characterized the respondents' demographics. The motivational aspects were analysed quantitatively by regression analyses. Thematic analyses were performed for the free text responses on motivational aspects. RESULTS: 239 respondents from the UK, Denmark, Norway, Sweden, The Netherlands, Ireland, and Malta completed the survey's motivation section. Increased knowledge and new challenges were the most motivating factors for becoming a reporting radiographer, while less exposure to radiation and less patient contact were the least motivating factors. Job satisfaction was a significant motivator. Gender significantly correlated with the importance of social connections for female reporting radiographers. A cross-country comparison showed that title and position and job security were more important for reporting radiographers from the UK. CONCLUSION: Taking in consideration that a sample of 239 is not generalisable for the role, this survey does provides insights into the motivation behind being a reporting radiographer in Europe. Factors such as increased knowledge, new challenges, and job satisfaction play significant roles. Hindrances experienced by reporting radiographers included lack of time, support, and standards, while aspirations for further professional development were expressed. IMPLICATIONS FOR PRACTICE: A thorough understanding of the motivation behind pursuing postgraduate studies in reporting radiography is a valuable tool for managers, aiding in fostering a positive work environment and attracting/keeping qualified personnel. The findings of this study can be employed in the development of strategies to support and enhance the practice of reporting radiographers.

Reporting radiographers in Europe survey: Support, role satisfaction, and advanced clinical practice within the European federation of radiographer society (EFRS) member countries.

INTRODUCTION: Increasing number of radiographers are undertaking image reporting throughout Europe. However, there are variations in practice and experience in European countries. The study aim was to investigate reporting radiographer's perceptions in relation to support for their role and workload satisfaction and elements of advanced practice that may also be undertaken. METHODS: Following institutional ethical approval an online 34 item questionnaire survey was circulated via social media; Twitter, Facebook, and LinkedIn in a 12-week period in 2022 across Europe. The survey data were managed by the online secure database REDCap (Research Electronic Data Capture). Data was collected across a range of questions, of which those relating to support for, and barriers to radiographer reporting, role and job satisfaction, and other role elements are reported here. RESULTS: A response level of 345 individual reporting radiographers replied to the survey from 15 European countries; some questions were optional and therefore had a lower response rate. There was consensus about the need for support from radiologists and management, protected time, and funding to support the reporting role. The majority of respondents received additional pay for taking on this role and expressed satisfaction with their role and workload. In relation to elements of advanced practice, the majority of respondents were involved in educational and managerial activities, and there was interest, but limited involvement, in research. CONCLUSION: There was a consensus about the support needed, and perceived barriers to, radiographer reporting, between reporting radiographers from different countries. Whilst there is some commonality in relation to activities such as supervision and education, there was clearer variety in relation to opportunities for research between the respondents, perhaps reflecting the differences between reporting as a standalone role development and reporting as part of an advanced clinical practice role. IMPLICATIONS FOR PRACTICE: As there is increasingly an emphasis on advanced clinical practice, reporting radiographers are likely to require support to develop their skills so that they can actively participate in the broader activities associated with this role, including education, leadership, and research.

Reporting radiographers in Europe survey: An overview of the role within the European Federation of Radiographer Society (EFRS) member countries.

INTRODUCTION: Reporting radiographers undertake an important role in healthcare and for the radiographer profession in general. First introduced in the United Kingdom, reporting radiographers are now practicing in several other European countries. Our objective was to investigate the workforce of reporting radiographers across the European Federation of Radiographer Societies (EFRS) community. METHOD AND MATERIAL: A voluntary anonymous 34 item electronic survey was distributed online using social media accounts such as Twitter, Facebook and LinkedIn covering a wide range of topics relating to professional role, advanced practice, education, and seniority. The questionnaire was distributed during a 12-week period in 2022. RESULT: A total of 345 individual responses were received from 15 countries with majorities of respondent from United Kingdom (n = 245, 71%) and Denmark (n = 66, 19%). Mean age was 41.9 (S.D 9.8), similar for females, 42.5 (S.D 9.0) and men 40.9 years (S.D 9.7). Most reporting radiographers worked in public hospitals (90%). The vast majority of the respondents (n = 270, n = 94%) authored and signed their own clinical reports while a minority (n = 18, 6%) stated that their reports were checked by radiologists. CONCLUSION: The survey highlights the scope of practice of reporting radiographers working in Europe. Reporting is becoming a career path for an increasing number of radiographers across Europe and there is assess to academic education and clinical support. IMPLICATION FOR PRACTICE: Reporting radiographers fulfil an important role within the current demands of healthcare. This demand is likely to increase in the future, and therefore it is vital that there is some form of standardisation in the level of education that this group of healthcare professionals receive.

Accuracy and economic evaluation of screening tests for undiagnosed COPD among hypertensive individuals in Brazil.

In Brazil, prevalence of diagnosed COPD among adults aged 40 years and over is 16% although over 70% of cases remain undiagnosed. Hypertension is common and well-recorded in primary care, and frequently co-exists with COPD because of common causes such as tobacco smoking, therefore we conducted a cross-sectional screening test accuracy study in nine Basic Health Units in Brazil, among hypertensive patients aged ≥40 years to identify the optimum screening test/combinations to detect undiagnosed COPD. We compared six index tests (four screening questionnaires, microspirometer and peak flow) against the reference test defined as those below the lower limit of normal (LLN-GLI) on quality diagnostic spirometry, with confirmed COPD at clinical review. Of 1162 participants, 6.8% (n = 79) had clinically confirmed COPD. Peak flow had a higher specificity but lower sensitivity than microspirometry (sensitivity 44.3% [95% CI 33.1, 55.9], specificity 95.5% [95% CI 94.1, 96.6]). SBQ performed well compared to the other questionnaires (sensitivity 75.9% [95% CI 65.0, 84.9], specificity 59.2% [95% CI 56.2, 62.1]). A strategy requiring both SBQ and peak flow to be positive yielded sensitivity of 39.2% (95% CI 28.4, 50.9) and specificity of 97.0% (95% CI 95.7, 97.9). The use of simple screening tests was feasible within the Brazilian primary care setting. The combination of SBQ and peak flow appeared most efficient, when considering performance of the test, cost and ease of use (costing £1690 (5554 R$) with 26.7 cases detected per 1,000 patients). However, the choice of screening tests depends on the clinical setting and availability of resources.ISRCTN registration number: 11377960.

From breathless to failure: symptom onset and diagnostic meaning in patients with heart failure-a qualitative study.

OBJECTIVES: To explore 2 key points in the heart failure diagnostic pathway-symptom onset and diagnostic meaning-from the patient perspective. DESIGN: Qualitative interview study. SETTING: Participants were recruited from a secondary care clinic in central England following referral from primary care. PARTICIPANTS: Over age 55 years with a recent (<1 year) diagnosis of heart failure confirmed by a cardiologist following initial presentation to primary care. METHODS: Semistructured interviews were carried out with 16 participants (11 men and 5 women, median age 78.5 years) in their own homes. Data were audio-recorded and transcribed. Participants were asked to describe their diagnostic journey from when they first noticed something wrong up to and including the point of diagnosis. Data were analysed using the framework method. RESULTS: Participants initially normalised symptoms and only sought medical help when daily activities were affected. Failure to realise that anything was wrong led to a delay in help-seeking. Participants' understanding of the term 'heart failure' was variable and 1 participant did not know he had the condition. The term itself caused great anxiety initially but participants learnt to cope with and accept their diagnosis over time. CONCLUSIONS: Greater public awareness of symptoms and adequate explanation of 'heart failure' as a diagnostic label, or reconsideration of its use, are potential areas of service improvement.

Choir singing and health status in people affected by cancer.

Cancer survival rates have improved dramatically over recent years, however, health-related quality of life (HRQoL) for many patients, survivors and their families remains low even after successful treatment. This mixed-methods observational study explored the effects of participation in community choirs on HRQoL in individuals who have had cancer (patients) or have been affected by cancer (non-patients). This included a longitudinal analysis of choristers commencing the Tenovus Cancer Care "Sing with Us" choirs across Wales and a series of semi-structured interviews and focus groups. Participants completed the Short-form 36 and the Hospital Anxiety and Depression Scale on commencement of the choir and 3 and 6 months later. On joining the choir, several domains of the SF36 were lower, indicating worse HRQoL and greater depression in patients than non-patients (p < .05). In patients, choir participation improved vitality, overall mental health and anxiety. In non-patients, choir participation improved anxiety (p < .05). Participants experienced the choirs as both an uplifting musical activity and a supportive community group. The results support the provision of a spectrum of support options to meet the different needs and preferences of people affected by cancer.

Abnormalities in left inferior frontal gyral thickness and parahippocampal gyral volume in young people at high genetic risk for bipolar disorder.

BACKGROUND: Fronto-limbic structural brain abnormalities have been reported in patients with bipolar disorder (BD), but findings in individuals at increased genetic risk of developing BD have been inconsistent. We conducted a study in adolescents and young adults (12-30 years) comparing measures of fronto-limbic cortical and subcortical brain structure between individuals at increased familial risk of BD (at risk; AR), subjects with BD and controls (CON). We separately examined cortical volume, thickness and surface area as these have distinct neurodevelopmental origins and thus may reflect differential effects of genetic risk. METHOD: We compared fronto-limbic measures of grey and white matter volume, cortical thickness and surface area in 72 unaffected-risk individuals with at least one first-degree relative with bipolar disorder (AR), 38 BD subjects and 72 participants with no family history of mental illness (CON). RESULTS: The AR group had significantly reduced cortical thickness in the left pars orbitalis of the inferior frontal gyrus (IFG) compared with the CON group, and significantly increased left parahippocampal gyral volume compared with those with BD. CONCLUSIONS: The finding of reduced cortical thickness of the left pars orbitalis in AR subjects is consistent with other evidence supporting the IFG as a key region associated with genetic liability for BD. The greater volume of the left parahippocampal gyrus in those at high risk is in line with some prior reports of regional increases in grey matter volume in at-risk subjects. Assessing multiple complementary morphometric measures may assist in the better understanding of abnormal developmental processes in BD.

Specifically horizontally tethered DNA probes on Au surfaces allow labelled and label-free DNA detection using SERS and electrochemically driven melting.

Controlled covalent attachment of dsDNA horizontally orientated on a gold surface is achieved through the use of a single surface-linker located approximately half way along the attached DNA probe strand. We show that horizontally oriented dsDNA on a gold surface can undergo melting and re-hybridization to target strand in solution and thus can be used for the detection of specific target DNA sequences using surface-enhanced Raman spectroscopy (SERS). We show that a range of lengths of target DNA sequences from ∼30-bases to 78-bases can be specifically hybridized to the short immobilized DNA probe sequence and adopt a horizontal orientation on the gold surface. Following thermal or electrochemically driven melting of the immobilized dsDNA, the target DNA strand diffuses away while the probe strand remains attached to the surface allowing the functionalized surfaces to be reused. The melting of the horizontally orientated immobilized dsDNA can be monitored using SERS either by employing a dye label covalently attached on the DNA target strand or by employing a binding agent selective for dsDNA. This approach of covalently immobilizing the DNA probe strand through a linker located at approximately the middle of the strand has great potential to improve the sensitivity and specificity of molecular assays that employ DNA arrays on solid surfaces.

A survey investigating the associations between self-management practices and quality of life in cancer survivors.

PURPOSE: To explore whether the use of self-management (SM) practices in cancer survivors impact on their health beliefs and quality of life (QoL). This is an important step in attempting to improve cancer survivors' health pathways and their experiences of living with cancer. METHODS: A cross-sectional, postal survey study was undertaken amongst cancer survivors identified from a teaching hospital in the West Midlands, UK. The questionnaire collected demographic data from respondents and information on the number and types of SM practices-diet, exercise, complementary and alternative medicine (CAM), psychological therapies, support groups and spirituality/religion-cancer survivors used after completing their treatment. Information was also gathered regarding their QoL and internal health locus of control (HLC). RESULTS: A total of 445 cancer survivors responded to the survey. Multi-linear regression analysis found a positive association between SM uptake and HLC; however, none was found between SM uptake and QoL. Treatment type, ethnicity and age were significantly associated with an increased use of SM practices. CONCLUSION: The study findings have implications for health care providers, who need to be aware of the links between SM uptake and treatment type, ethnicity and age, when considering how best to incorporate SM into cancer survivors' lives. This can help cancer survivors who may benefit from using specific SM interventions that consider the socio-demographic and treatment-related factors impacting on them. Future research would benefit from assessing the motivations and benefits of cancer survivors of different ages, ethnicities and treatment modalities in terms of their decision-making about SM use. These findings suggest that SM uptake is associated with higher internal HLC in cancer survivors. However, the influence of treatment type, ethnicity and age plays a more significant role in determining SM uptake than HLC. Cancer survivors using SM may be more motivated to utilise SM practices in relation to their age, ethnicity and treatment type, generating positive health outcomes in the process. Policy-makers should be aware of the supportive role SM interventions can play in cancer care and survivorship, with future research focussing on the perceived benefit of these SM interventions to cancer survivors.

Strain discrimination of Yersinia pestis using a SERS-based electrochemically driven melting curve analysis of variable number tandem repeat sequences.

Strain discrimination within genetically highly similar bacteria is critical for epidemiological studies and forensic applications. An electrochemically driven melting curve analysis monitored by SERS has been utilised to reliably discriminate strains of the bacterial pathogen Yersinia pestis, the causative agent of plague. DNA amplicons containing Variable Number Tandem Repeats (VNTRs) were generated from three strains of Y. pestis: CO92, Harbin 35 and Kim. These amplicons contained a 10 base pair VNTR repeated 6, 5, and 4 times in CO92, Harbin 35 and Kim respectively. The assay also included a blocker oligonucleotide comprising 3 repeats of the 10-mer VNTR sequence. The use of the blocker reduced the effective length of the target sequence available to bind to the surface bound probe and significantly improved the sensitivity of the discrimination. The results were consistent during three replicates that were carried out on different days, using different batches of PCR product and different SERS sphere segment void (SSV) substrate. This methodology which combines low cost, speed and sensitivity is a promising alternative to the time consuming current electrophoretic methods.

Patterns of self-management practices undertaken by cancer survivors: variations in demographic factors.

The study purpose was to examine self-management (SM) use among cancer survivors; and to explore variations in uptake of SM in survivorship and whether these differed in relation to age, income, gender, ethnicity, cancer type and treatment type. This is an important area for exploration as SM utilisation has the potential to impact on the health status, health behaviours and quality of life (QoL) of cancer survivors. A postal survey was conducted among 445 cancer survivors identified from a hospital in the West Midlands, UK. Demographic data were collected and respondents were asked to identify which practices across six SM categories - diet, exercise, complementary and alternative medicine (CAM), psychological therapies, support groups and spirituality/religion - they had used (if any). The findings indicate that the large majority (91%) had used some form of SM after their cancer treatment. Exercise (84%) and diet (56%) were the most popular SM interventions for cancer survivors and socio-demographic and cancer-related factors were associated with SM uptake. These findings can form the basis for designing and implementing appropriate SM interventions aimed at improving the health, well-being and QoL of cancer survivors.

EphA2 promotes infiltrative invasion of glioma stem cells in vivo through cross-talk with Akt and regulates stem cell properties.

Diffuse infiltrative invasion is a major cause for the dismal prognosis of glioblastoma multiforme (GBM), but the underlying mechanisms remain incompletely understood. Using human glioma stem cells (GSCs) that recapitulate the invasive propensity of primary GBM, we find that EphA2 critically regulates GBM invasion in vivo. EphA2 was expressed in all seven GSC lines examined, and overexpression of EphA2 enhanced intracranial invasion. The effects required Akt-mediated phosphorylation of EphA2 on serine 897. In vitro the Akt-EphA2 signaling axis is maintained in the absence of ephrin-A ligands and is disrupted upon ligand stimulation. To test whether ephrin-As in tumor microenvironment can regulate GSC invasion, the newly established Efna1;Efna3;Efna4 triple knockout mice (TKO) were used in an ex vivo brain slice invasion assay. We observed significantly increased GSC invasion through the brain slices of TKO mice relative to wild-type (WT) littermates. Mechanistically EphA2 knockdown suppressed stem cell properties of GSCs, causing diminished self-renewal, reduced stem marker expression and decreased tumorigenicity. In a subset of GSCs, the reduced stem cell properties were associated with lower Sox2 expression. Overexpression of EphA2 promoted stem cell properties in a kinase-independent manner and increased Sox2 expression. Disruption of Akt-EphA2 cross-talk attenuated stem cell marker expression and neurosphere formation while having minimal effects on tumorigenesis. Taken together, the results show that EphA2 endows invasiveness of GSCs in vivo in cooperation with Akt and regulates glioma stem cell properties.

Desmosomes in verrucous carcinoma of the head and neck.

Verrucous carcinoma (VC) is a variant of squamous cell carcinoma (SCC), characterised by its inability to metastasize. In contrast, hybrid carcinomas, composed of VC and foci of conventional SCC, harbour a metastatic potential. Correct pathohistological diagnosis is therefore crucial for the choice of treatment. There is mounting evidence that desmosomes are involved in several aspects of carcinogenesis. Previous studies have shown an altered expression of desmosomal components in conventional SCC, which was associated with tumour behaviour, but no data have been found on desmosomes in VC. We therefore analysed the expression of desmosomal components in biopsy samples of 21 cases of VC and 5 cases of hybrid carcinoma of the head and neck in comparison to 23 cases of conventional SCC and 47 samples of normal squamous epithelium of similar localisation, using immunohistochemistry and real-time reverse-transcription polymerase chain reaction. We found that the expression patterns of desmosomal components in VC were fairly similar to those in normal epithelium but differed significantly from those in conventional SCC. Immunohistochemical reactions against desmosomal components disclosed the foci of SCC in hybrid carcinomas. In conclusion, we believe that expression patterns of desmosomal components in VC are consistent with its less aggressive behaviour. Differential expression of desmosomal components between VC and SCC makes some desmosomal components potentially useful in the diagnostics of VC, especially for the detection of hybrid carcinoma.

Salivary gland tumours as second neoplasms: two cases and literature review.

OBJECTIVES: Patients who survive malignant tumours have an increased risk of second neoplasms, including those of the salivary glands. Mucoepidermoid carcinoma of the parotid gland is by far the most common type of second salivary gland tumour; other types have rarely been reported. We describe here two patients with a second tumour of the salivary glands. CASE REPORTS: The first patient was a 22-year-old woman with a low grade mucoepidermoid carcinoma of the parotid gland, which developed 21 years after completion of chemoradiotherapy for acute lymphoblastic leukaemia. The second patient was a 40-year-old woman with an epithelial-myoepithelial carcinoma of the buccal mucosa, which arose 11 years after treatment for two malignant neoplasms - retroperitoneal liposarcoma and squamous cell carcinoma of the uterine cervix. CONCLUSIONS: It is mandatory that survivors of cancer should be monitored carefully, so that the complications related to their previous disease and therapy are detected early and managed properly.

Interrogation of short tandem repeats using fluorescent probes and melting curve analysis: a step towards rapid DNA identity screening.

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR SGM Plus system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1h.

Delta-like ligand 4 (Dll4) is induced by VEGF as a negative regulator of angiogenic sprouting.

Genetic deletion studies have shown that haploinsufficiency of Delta-like ligand (Dll) 4, a transmembrane ligand for the Notch family of receptors, results in major vascular defects and embryonic lethality. To better define the role of Dll4 during vascular growth and differentiation, we selected the postnatal retina as a model because its vasculature develops shortly after birth in a highly stereotypic manner, during which time it is accessible to experimental manipulation. We report that Dll4 expression is dynamically regulated by VEGF in the retinal vasculature, where it is most prominently expressed at the leading front of actively growing vessels. Deletion of a single Dll4 allele or pharmacologic inhibition of Dll4/Notch signaling by intraocular administration of either soluble Dll4-Fc or a blocking antibody against Dll4 all produced the same set of characteristic abnormalities in the developing retinal vasculature, most notably enhanced angiogenic sprouting and increased endothelial cell proliferation, resulting in the formation of a denser and more highly interconnected superficial capillary plexus. In a model of ischemic retinopathy, Dll4 blockade also enhanced angiogenic sprouting and regrowth of lost retinal vessels while suppressing ectopic pathological neovascularization. Our data demonstrate that Dll4 is induced by VEGF as a negative feedback regulator and acts to prevent overexuberant angiogenic sprouting, promoting the timely formation of a well differentiated vascular network.

Pseudovascular adenoid squamous-cell carcinoma of the oral cavity--a report of two cases.

Informed consent was obtained for the publication of the patients' details in this report. Two cases of pseudovascular adenoid squamous-cell carcinoma (SCC) in the oral cavity are described, which were characterised by acantholysis of the tumour cells, with formation of anastomosing spaces and channels mimicking an angiosarcoma. Both tumours contained foci of SCC suggesting the correct diagnosis: in one patient conventional SCC, and in the other, a spindle-cell carcinoma. The pathogenesis of pseudovascular adenoid SCC is unknown. Our cases were characterised by loss of immunohistochemical expression of E-cadherin, one of the major adhesion molecules of epithelial cells. Pseudovascular adenoid SCC is suggested to be pathogenetically related to the loss of E-cadherin expression, leading to the loss of tumour cell-cell adhesion.

Distribution of Epstein-Barr virus genotypes in throat washings, sera, peripheral blood lymphocytes and in EBV positive tumor biopsies from Slovenian patients with nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is a malignancy closely associated with Epstein-Barr virus (EBV). It is prevalent among the Chinese of Southern China, whereas outside China, the position seems to be different. The aim of this study was to determine the distribution of EBV genotypes in the patients with NPC in Slovenia, which is a nonendemic area. Detection of EBV was undertaken by testing the throat washes, sera, peripheral blood lymphocytes (PBLs), and biopsies of primary tumors of 48 patients with NPC in Slovenia. The sera of 20 patients with serologically confirmed primary EBV infection served as a control clinical material. The analysis of genotypes was carried out on three regions of EBV genome; BamHI WYH, BamHI I, and BamHI F, using the polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The results show that, in Slovenia, the predominant combination of EBV genotypes based on the differences in the three genomic regions is ADF. This combination was found in 56 out of 103 different EBV positive clinical samples (throat washes, sera, PBLs, and tumor biopsies) of patients with NPC and in 15 out of 17 sera of patients with primary EBV infection. Very low number of genotypes C and f were detected, in spite of the fact that these two genotypes were considered to be associated with the development and/or maintenance of NPC in Southern China. Genotype f was found in only two tumor biopsies; in all other clinical samples (throat washes, sera and PBLs), genotype F was detected. Genotype C was proven in 31/103 clinical samples, with the highest percentage in tumor biopsies (37.5%). As in the NPC patients from other countries (Alaska is an exception), genotype A was predominant and was detected in 86/103 clinical samples. Genotype B was found in 15 clinical samples of patients with NPC and in 3 the two genotypes A and B were found. In comparison to China, these results show different EBV genotypes distribution. It seems that the genetic disposition of human population is an important factor that may contribute to different susceptibility for specific EBV genotypes.
