Returning to education after childhood acquired brain injury: Learning from lived parental experience.

BACKGROUND: Returning to education (RtE) after an acquired brain injury (ABI) can be stressful for children/young people (CYP) and families. While much can be done to support RtE, there has been limited exploration of the lived experience of parents/carers about what can both help and hinder the process. OBJECTIVE: The aim was to understand more about RtE from parents' perspectives to inform best practice and facilitate improvements in service delivery. METHODS: A service evaluation explored parent/carer views about the RtE process and the support received from healthcare professionals at a regional centre in the UK. Questionnaires (n = 59) were sent to parents of patients treated for an ABI in the last two years. RESULTS: 31 parents (response rate = 51%) completed the survey. Results highlight the many challenges of RtE. Thematic analysis of responses revealed six key themes: Parental mindset and growth; What do they need now?; Specialist support and information; Talk and share; Challenges of new and hidden needs; and Don't forget them! CONCLUSION: Parents offer crucial insight into the challenges of the RtE process. Their feedback highlights important factors for service development and reminds professionals of the key components of an effective return.

Protocol for the ORION trial (RadiO fRequency ablatION for haemorrhoids): a randomised controlled trial.

BACKGROUND: Haemorrhoids are common and can significantly impact the personal and working lives of individuals. Those with more severe symptoms and those not responding to conservative management may require surgery. Current surgical techniques are associated with a degree of postoperative discomfort which may delay return to normal activity. Recurrence is lower in more radical procedures but resulting pain is higher. Radiofrequency ablation (RFA) is a new technique that is gaining popularity and has several hypothesised benefits, including reduced pain and recurrence. However, available evidence is limited. A recent overview from the National Institute for Health and Clinical Excellence recommended more research, in the form of randomised controlled trials, be carried out before further investment is made by national health services. Our aim is to assess whether RFA is at least as good in terms of recurrence as existing surgical interventions, but superior in terms of pain, for patients with symptomatic grade II and III haemorrhoids. METHODS: The RadiO fRequency ablatION for haemorrhoids (ORION) trial will be a pragmatic multicentre patient/assessor-blind parallel group-controlled trial with economic evaluation. The target sample size is 376 participants (188 per arm) and is based on two co-primary endpoints: (i) a non-inferiority design for recurrence and (ii) superiority design for pain at seven days. Participants with grade II or III haemorrhoids will be recruited in 16 National Health Service hospitals and randomised (1:1) to either RFA or surgeon's choice of surgery. CONCLUSIONS: Results will inform future practice for the treatment of grade II-III haemorrhoids and provide evidence for national health services on future investments in RFA. TRIAL REGISTRATION: ISRCTN14474552.

A machine-learning assisted review of the use of habit formation in medication adherence interventions for long-term conditions.

Adherence to medication in long-term conditions is around 50%. The key components of successful interventions to improve medication adherence remain unclear, particularly when examined over prolonged follow-up periods. Behaviour change theories are increasingly interested in the utility of habit formation for the maintenance of health behaviour change, but there is no documentation on how habit has been conceptualised in the medication adherence intervention literature, or what effect the key technique identified in habit formation theory (context dependent repetition) has in these studies. To examine this, a machine-learning assisted review was conducted. Searches of MEDLINE, EMBASE and PSYCInfo and the reference list of a comprehensive systematic review of medication adherence interventions yielded 5973 articles. Machine learning-assisted title and abstract screening identified 15 independent RCTs published between 1976 and 2021, including 18 intervention comparisons of interest. Key findings indicate that conceptualisations of habit in the medication adherence literature are varied and behaviour change technique coding identified only six studies which explicitly described using habit formation. Future work should aim to develop this evidence base, drawing on contemporary habit theory and with explicit demonstration of what techniques have been used to promote habit formation.

Linkage to care after HIV diagnosis among men who have sex with men and transgender women in Lima, Peru.

In Lima, Perú, HIV prevalence is estimated to be 15% among men who have sex with men (MSM) and 30% among transgender women (TW). We investigated timely linkage of MSM and TW to HIV care, as linkage to antiretroviral therapy (ART) is critical to protect the health of those living with HIV and to prevent onward transmission. We investigated linkage within 90 days of HIV diagnosis by matching data from two studies conducted in Lima between 2013 and 2015 to national ART program records. We used generalized linear modeling to assess predictors of timely linkage and late presentation to care. Of 487 newly-diagnosed MSM and TW, only 44% presented for care at an HIV clinic within 90 days. Timely linkage was less common among TW (aPR 0.7, 95% CI 0.5-1.0), those younger than 24 (aPR 0.8, 95% CI 0.6-1.0), and those reporting a history of sex work (aPR 0.7, 95% CI 0.6-0.9). Proximity to an ART program clinic was not associated with linkage; most participants linked to clinics offering "LGBTQ-friendly" care. The pattern of clinics selected by participants suggests the importance of concerns about confidentiality and stigma in decision-making about where to link to care.

Perinatal mental healthcare in Northern Ireland: challenges and opportunities.

Perinatal mental health is a vital component of public mental health. The perinatal period represents the time in a woman's life when she is at the highest risk of developing new-onset psychiatric disorders or relapse of an existing mental illness. Optimisation of maternal mental health in the perinatal period is associated with both short- and long-term benefits not only for the mother, but also for her infant and family. However, perinatal mental health service provision remains variable across the world. At present in Northern Ireland, 80% of women do not have access to specialist community perinatal mental health services, and without access to a mother and baby unit, mothers who require a psychiatric admission in the postnatal period are separated from their baby. However, following successful campaigns, funding for development of specialist perinatal mental health community teams has recently been approved. In this article, we discuss the importance of perinatal mental health from a public health perspective and explore challenges and opportunities in the ongoing journey of specialist service development in Northern Ireland.

Factors Associated With Health-Related Quality of Life Among Cancer Survivors in the United States.

Background: With increasing prevalence of cancer survivors in the United States, health-related quality of life (HRQOL) has become a major priority. We describe HRQOL in a nationally representative sample of cancer survivors and examine associations with key sociodemographic, clinical, and lifestyle characteristics. Methods: Cancer survivors, defined as individuals ever diagnosed with cancer (N = 877), were identified from the 2016 Medical Expenditure Panel Survey-Experiences with Cancer Survivorship Supplement, a nationally representative survey. Physical and mental health domains of HRQOL were measured by the Global Physical Health (GPH) and Global Mental Health (GMH) subscales of the Patient-Reported Outcomes Measurement Information System Global-10. Multivariable linear regression was used to examine associations of sociodemographic, clinical, and lifestyle factors with GPH and GMH scores. All statistical tests were 2-sided. Results: Cancer survivors' mean GPH (49.28, SD = 8.79) and mean GMH (51.67, SD = 8.38) were similar to general population means (50, SD = 10). Higher family income was associated with better GPH and GMH scores, whereas a greater number of comorbidities and lower physical activity were statistically significantly associated with worse GPH and GMH. Survivors last treated 5 years ago and longer had better GPH than those treated during the past year, and current smokers had worse GMH than nonsmokers (all ß > 3 and all P < .001). Conclusions: Cancer survivors in the United States have generally good HRQOL, with similar physical and mental health scores to the general US population. However, comorbidities, poor health behaviors, and recent treatment may be risk factors for worse HRQOL. Multimorbidity management and healthy behavior promotion may play a key role in maximizing HRQOL for cancer survivors.

Magneto-optical diagnosis of symptomatic malaria in Papua New Guinea.

Improved methods for malaria diagnosis are urgently needed. Here, we evaluate a novel method named rotating-crystal magneto-optical detection (RMOD) in 956 suspected malaria patients in Papua New Guinea. RMOD tests can be conducted within minutes and at low cost. We systematically evaluate the capability of RMOD to detect infections by directly comparing it with expert light microscopy, rapid diagnostic tests and polymerase chain reaction on capillary blood samples. We show that compared to light microscopy, RMOD exhibits 82% sensitivity and 84% specificity to detect any malaria infection and 87% sensitivity and 88% specificity to detect Plasmodium vivax. This indicates that RMOD could be useful in P. vivax dominated elimination settings. Parasite density correlates well with the quantitative magneto-optical signal. Importantly, residual hemozoin present in malaria-negative patients is also detectable by RMOD, indicating its ability to detect previous infections. This could be exploited to reveal transmission hotspots in low-transmission settings.

Social Susceptibility to Multiple Air Pollutants in Cardiovascular Disease.

INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of death in the United States, and substantial research has linked ambient air pollution to elevated rates of CVD etiology and events. Much of this research identified increased effects of air pollution in lower socioeconomic position (SEP) communities, where pollution exposures are also often higher. The complex spatial confounding between air pollution and SEP makes it very challenging, however, to disentangle the impacts of these very different exposure types and to accurately assess their interactions. The specific causal components (i.e., specific social stressors) underlying this SEP-related susceptibility remain unknown, because there are myriad pathways through which poverty and/or lower-SEP conditions may influence pollution susceptibility - including diet, smoking, coexposures in the home and occupational environments, health behaviors, and healthcare access. Growing evidence suggests that a substantial portion of SEP-related susceptibility may be due to chronic psychosocial stress - given the known wide-ranging impacts of chronic stress on immune, endocrine, and metabolic function - and to a higher prevalence of unpredictable chronic stressors in many lower-SEP communities, including violence, job insecurity, and housing instability. As such, elucidating susceptibility to pollution in the etiology of CVD, and in the risk of CVD events, has been identified as a research priority. This interplay among social and environmental conditions may be particularly relevant for CVD, because pollution and chronic stress both impact inflammation, metabolic function, oxidative stress, hypertension, atherosclerosis, and other processes relevant to CVD etiology. Because pollution exposures are often spatially patterned by SEP, disentangling their effects - and quantifying any interplay - is especially challenging. Doing so, however, would help to improve our ability to identify and characterize susceptible populations and to improve our understanding of how community stressors may alter responses to multiple air pollutants. More clearly characterizing susceptible populations will improve our ability to design and target interventions more effectively (and cost-effectively) and may reveal greater benefits of pollution reduction in susceptible communities, strengthening cost-benefit and accountability analyses, ultimately reducing the disproportionate burden of CVD and reducing health disparities. METHODS: In the current study, we aimed to quantify combined effects of multiple pollutants and stressor exposures on CVD events, using a number of unique datasets we have compiled and verified, including the following. 1. Poverty metrics, violent crime rates, a composite socioeconomic deprivation index (SDI), an index of racial and economic segregation, noise disturbance metrics, and three composite spatial factors produced from a factor analysis of 27 community stressors. All indicators have citywide coverage and were verified against individual reports of stress and stressor exposure, in citywide focus groups and surveys. 2. Spatial surfaces for multiple pollutants from the New York City (NYC) Community Air Survey (NYCCAS), which monitored multiple pollutants year-round at 150 sites and used land use regression (LUR) modeling to estimate fine-scale (100-m) intra-urban spatial variance in fine particles (PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3). 3. Daily data and time-trends derived from all U.S. Environmental Protection Agency (EPA) Air Quality System (AQS) monitors in NYC for 2005-2011, which we combined with NYCCAS surfaces to create residence- and day-specific spatiotemporal exposure estimates. 4. Complete data on in- and out-patient unscheduled CVD events presented in NYC hospitals for 2005-2011 (n = 1,113,185) from the New York State (NYS) Department of Health's Statewide Planning and Research Cooperative System (SPARCS). In the study, we quantified relationships between multiple pollutant exposures and both community CVD event rates and individual risk of CVD events in NYC and tested whether pollution-CVD associations varied by community SEP and social stressor exposures. We hypothesized (1) that greater chronic community-level SEP, stressor, and pollution exposures would be associated with higher community CVD rates; (2) that spatiotemporal variations in multiple pollutants would be associated with excess risk of CVD events; and (3) that pollution-CVD associations would be stronger in communities of lower SEP or higher stressor exposures. RESULTS: To first understand the separate and combined associations with CVD for both stressors and pollutants measured at the same spatial and temporal scale of resolution, we used ecological cross-sectional models to examine spatial relationships between multiple chronic pollutant and stressor exposures and age-adjusted community CVD rates. Using census-tract-level annual averages (n = 2,167), we compared associations with CVD rates for multiple pollutant concentrations and social stressors. We found that associations with community CVD rates were consistently stronger for social stressors than for pollutants, in terms of both magnitude and significance. We note, however, that this result may be driven by the relatively greater variation (on a proportional basis) for stressors than for pollutants in NYC. We also tested effect modification of pollutant-CVD associations by each social stressor and found evidence of stronger associations for NO2, PM2.5, and wintertime SO2 with CVD rates, particularly across quintiles of increasing community violence or assault rates (P trend < 0.0001). To examine individual-level associations between spatiotemporal exposures to multiple pollutants and the risk of CVD events, across multiple lag days, we examined the combined effects of multiple pollutant exposures, using spatiotemporal (day- and residence-specific) pollution exposure estimates and hospital data on individual CVD events in case-crossover models, which inherently adjust for nontime-varying individual confounders (e.g., sex and race) and comorbidities. We found consistent significant relationships only for same-day pollutant exposures and the risk of CVD events, suggesting very acute impacts of pollution on CVD risk. Associations with CVD were positive for NO2, PM2.5, and SO2, as hypothesized, and we found inverse associations for O3 (a secondary pollutant chemically decreased ["scavenged"] by fresh emissions that, in NYC, displays spatial and temporal patterns opposite those of NO2). Finally, to test effect modification by chronic community social stressors on the relationships between spatiotemporal pollution measures and the risk of CVD events, we used individual-level case-crossover models, adding interaction terms with categorical versions of each social stressor. We found that associations between NO2 and the risk of CVD events were significantly elevated only in communities with the highest exposures to social stressors (i.e., in the highest quintiles of poverty, socioeconomic deprivation, violence, or assault). The largest positive associations for PM2.5 and winter SO2 were generally found in the highest-stressor communities but were not significant in any quintile. We again found inverse associations for O3, which were likewise stronger for individuals living in communities with greater stressor exposures. CONCLUSIONS: In ecological models, we found stronger relationships with community CVD rates for social stressors than for pollutant exposures. In case-crossover analyses, higher exposures to NO2, PM2.5, and SO2 were associated with greater excess risk of CVD events but only on the case day (there were no consistent significant lagged-day effects). In effect-modification analyses at both the community and individual level, we found evidence of stronger pollution-CVD associations in communities with higher stressor exposures. Given substantial spatial confounding across multiple social stressors, further research is needed to disentangle these effects in order to identify the predominant social stressors driving this observed differential susceptibility.

Concomitant Congenital Intraoral Dermoid Cyst and Heterotopic Gastrointestinal Cyst.

Sublingual dermoid cysts and oral heterotopic gastrointestinal cysts are well-documented causes of sublingual swellings in infants. However, the simultaneous occurrence of both cysts is an extremely rare phenomenon, with only two previous cases reported in literature. We present a case of 1-month-old neonate with a cystic ventral tongue mass that on histologic examination showed a dermoid cyst with co-existing heterotopic gastric-type epithelium in the wall. Additional histochemical stains revealed focal areas of colonic metaplasia within the heterotopic gastric epithelium. CDX2 immunohistochemical staining confirmed derivation from colonic epithelium.

Crowdsourcing: A novel tool to elicit the student voice in the curriculum design process for an undergraduate diagnostic radiography degree programme.

INTRODUCTION: Stakeholder participation in healthcare curriculum design is an important aspect of higher education with stakeholders including students, staff members, clinical partners, healthcare organisations, patients and members of the public. Significantly, student co-creation, of the curriculum, has become increasingly important. Yet there is limited research which addresses how to engage this group in design processes. METHODS: This paper represents the first phase of a three stage action research spiral whereby the authors evaluated the use of a novel tool for curriculum design processes, anonymised crowdsourcing. This initial phase was open to all students enrolled on an undergraduate diagnostic radiography programme in the UK. To confirm the reliability of the crowdsource design an established eight point crowdsourcing verification tool was applied. RESULTS: Twenty-three unique ideas were generated by participants, 40 comments made and 173 votes cast. Inductive analysis of the comments generated five themes. These included: the role of technology enhanced learning; simulation activities; patient focused curriculum; mental wealth (resilience) authentic assessment approaches. An evaluation of those who had and had not engaged highlighted areas of improvement for the administration of the second and third iterations which will include a wider pool of participants. CONCLUSION: This study from a single programme offers lessons for others wishing to adopt and develop this approach elsewhere. IMPLICATIONS FOR PRACTICE: Several ideas elicited by the crowdsource have been considered by the curriculum design team and will be implemented in the 2020 curriculum thus demonstrating the impact on local education practice of this research approach.

Septum resection in women with a septate uterus: a cohort study.

STUDY QUESTION: Does septum resection improve reproductive outcomes in women with a septate uterus? SUMMARY ANSWER: In women with a septate uterus, septum resection does not increase live birth rate nor does it decrease the rates of pregnancy loss or preterm birth, compared with expectant management. WHAT IS KNOWN ALREADY: The septate uterus is the most common uterine anomaly with an estimated prevalence of 0.2-2.3% in women of reproductive age, depending on the classification system. The definition of the septate uterus has been a long-lasting and ongoing subject of debate, and currently two classification systems are used worldwide. Women with a septate uterus may be at increased risk of subfertility, pregnancy loss, preterm birth and foetal malpresentation. Based on low quality evidence, current guidelines recommend removal of the intrauterine septum or, more cautiously, state that the procedure should be evaluated in future studies. STUDY DESIGN, SIZE, DURATION: We performed an international multicentre cohort study in which we identified women mainly retrospectively by searching in electronic patient files, medical records and databases within the time frame of January 2000 until August 2018. Searching of the databases, files and records took place between January 2016 and July 2018. By doing so, we collected data on 257 women with a septate uterus in 21 centres in the Netherlands, USA and UK. PARTICIPANTS/MATERIALS, SETTING, METHODS: We included women with a septate uterus, defined by the treating physician, according to the classification system at that time. The women were ascertained among those with a history of subfertility, pregnancy loss, preterm birth or foetal malpresentation or during a routine diagnostic procedure. Allocation to septum resection or expectant management was dependent on the reproductive history and severity of the disease. We excluded women who did not have a wish to conceive at time of diagnosis. The primary outcome was live birth. Secondary outcomes included pregnancy loss, preterm birth and foetal malpresentation. All conceptions during follow-up were registered but for the comparative analyses, only the first live birth or ongoing pregnancy was included. To evaluate differences in live birth and ongoing pregnancy, we used Cox proportional regression to calculate hazard rates (HRs) and 95% CI. To evaluate differences in pregnancy loss, preterm birth and foetal malpresentation, we used logistic regression to calculate odds ratios (OR) with corresponding 95% CI. We adjusted all reproductive outcomes for possible confounders. MAIN RESULTS AND THE ROLE OF CHANCE: In total, 257 women were included in the cohort. Of these, 151 women underwent a septum resection and 106 women had expectant management. The median follow-up time was 46 months. During this time, live birth occurred in 80 women following a septum resection (53.0%) compared to 76 women following expectant management (71.7%) (HR 0.71 95% CI 0.49-1.02) and ongoing pregnancy occurred in 89 women who underwent septum resection (58.9%), compared to 80 women who had expectant management (75.5%) (HR 0.74 (95% CI 0.52-1.06)). Pregnancy loss occurred in 51 women who underwent septum resection (46.8%) versus 31 women who had expectant management (34.4%) (OR 1.58 (0.81-3.09)), while preterm birth occurred in 26 women who underwent septum resection (29.2%) versus 13 women who had expectant management (16.7%) (OR 1.26 (95% CI 0.52-3.04)) and foetal malpresentation occurred in 17 women who underwent septum resection (19.1%) versus 27 women who had expectant management (34.6%) (OR 0.56 (95% CI 0.24-1.33)). LIMITATIONS, REASONS FOR CAUTION: Our retrospective study has a less robust design compared with a randomized controlled trial. Over the years, the ideas about the definition of the septate uterus has changed, but since the 257 women with a septate uterus included in this study had been diagnosed by their treating physician according to the leading classification system at that time, the data of this study reflect the daily practice of recent decades. Despite correcting for the most relevant patient characteristics, our estimates might not be free of residual confounding. WIDER IMPLICATIONS OF THE FINDINGS: Our results suggest that septum resection, a procedure that is widely offered and associated with financial costs for society, healthcare systems or individuals, does not lead to improved reproductive outcomes compared to expectant management for women with a septate uterus. The results of this study need to be confirmed in randomized clinical trials. STUDY FUNDING/COMPETING INTEREST(S): A travel for JFWR to Chicago was supported by the Jo Kolk Studyfund.

Cu catalysts supported on CaO/MgO for glycerol conversion to lactic acid in alkaline medium employing a continuous flow reaction system.

The production of lactic acid (LA) from glycerol in alkaline medium was investigated using Cu catalysts supported on CaO, MgO and xCaO/MgO (x = 5, 10, 15 wt%), employing a continuous flow reaction system over a period of 30 h. In addition to assessing the effect of the composition of the catalytic support, the influence of the temperature (200-260 °C), NaOH/glycerol molar ratio (0.5-1.5), hydroxide type (NaOH and KOH), as well as the influence of concentration (10 and 20 vol%) and purity of glycerol was investigated. The catalysts were prepared by a wet impregnation method and characterized by XRF, XRD, N2 adsorption-desorption, H2-TPR and CO2-TPD. The catalytic tests showed that the use of NaOH results in higher yields to LA. Cu catalysts supported on xCaO/MgO exhibited better catalytic performance than the CuCa and CuMg catalysts. The LA yield increases with the increase of the reaction temperature from 200 to 240 °C, and then decreases with a subsequent increase to 260 °C. NaOH/glycerol molar ratios greater than 1.25 are not necessary, since high yield to LA (96.9%) was obtained in the catalytic test performed using a molar ratio of 1.25. The catalysts showed excellent stability without evidence of deactivation over the evaluated period.

A meta-analysis of toxicities related to hydroxycarbamide dosing strategies.

Due to fear of short-term toxicities, there is nonconsensus of hydroxycarbamide dosing strategy (escalated vs fixed-dosing methods), which contributes to its suboptimal use. We performed a meta-analysis to summarize the incidence rates of toxicities associated with both dosing methods. Summarized incidence rates could not be statistically compared between dosing methods due to sparse data. Summarized neutropenia and thrombocytopenia incidence rates were slightly higher when using escalated dosing than with fixed. Summarized reticulocytopenia was comparable. Summarized hepatic and renal toxicities' incidence rates were slightly higher when using fixed doses than with escalated. We recommend diligent and transparent reporting of toxicities.

Jumping to conclusions in persistent pain using a somatosensory modification of the beads task.

BACKGROUND: There is theoretical and empirical evidence that persistent pain occurs because of a distortion in top-down perceptual processes. 'Jumping to conclusions' (JTC) tasks, such as the beads task, purportedly capture these processes and have yet to be studied in people with chronic pain. However, the beads task uses visual stimuli, whereas tasks involving processing in the somatosensory domain seem at least more face valid in this population. This study uses a novel somatosensory adaptation of the beads task to explore whether a JTC reasoning style is more common in people with persistent pain compared controls. METHODS: 30 persistent pain patients and 30 age-, gender- and education-matched controls completed the visual beads JTC task and a novel somatosensory version of the JTC task that used tactile stimuli (vibrations to the fingertip). FINDINGS: Patients with persistent pain showed a 'jumping to conclusions' reasoning style on both tasks compared to the control group and there was no significant difference in the effect sizes on the two tasks. INTERPRETATION: This preliminarily study demonstrated that individuals with persistent pain show a JTC reasoning style to both visual and somatosensory stimuli. Future research should focus on establishing how or whether this bias directly influences the experience of persistent pain.

A review of visual ethnography: Radiography viewed through a different lens.

INTRODUCTION: The objective of this article is to provide a short review of the research methodology 'visual ethnography'. METHOD: The review article will provide a summary of the foundations of visual ethnography, outline the key debates and refer to some of the main authors working in this field. RESULTS: Visual Ethnography is both a methodology and a method of research. It should be selected for research in radiography when research questions seek to focus upon aspects or elements of a culture. A research plan that is designed using a visual ethnographic approach should be flexible and take into account the requirements of the researcher and research participants. Visual methods of research include the use of various images, for example, photographs, collage, film or drawings. Visual methods are commonly employed together with interviews, conversations and observation. The approach enables researchers to generate new and unique insights into cultures. CONCLUSION: This review of visual ethnography provides background information that informs an introduction to the methodology. It demonstrates a methodology with the potential to explore culture and expand knowledge of radiography practice. IMPLICATIONS FOR PRACTICE: The authors suggest that for future studies visual ethnography is a methodology that can expand the paradigm of radiography research.

An investigation into the perceived value of the College of Radiographers voluntary accreditation scheme for advanced and consultant practitioners in breast imaging.

INTRODUCTION: A voluntary accreditation scheme has been introduced, requiring advanced (AdP) and consultant practitioners (CP) to submit several pieces of work to the College of Radiographers (CoR). However, few individuals have opted to become voluntary accredited. This study investigated the reasons behind becoming voluntary accredited, the value that was gained and why there appears to be a lack of support for the scheme. METHODS: An online electronic survey was conducted using a mixed methods approach. Open questions enabled individual opinions and thoughts to be expressed, Likert scale style questions allowed further understanding of the level of agreement and closed questions identified the support for and against the scheme. RESULTS: A total of 55 respondents participated, including 18 AdPs, 25 CPs, 1 consultant trainee practitioner, 5 practitioners and 6 listed as 'other'. Forty-four participants were non-accredited, citing too much clinical work; no recognition from employers and too much effort for little reward. Motivations for joining the scheme were to improve the profession; help create a new consultant post and protect the non-clinical element of the consultant role. CONCLUSION: The CoR voluntary accreditation scheme has a small perceived value but overall, the majority of respondents believed the scheme did not warrant the work needed to apply. Concern was raised about the risk of creating a two-tier profession by the scheme's instigation. The results of this study suggest that the CoR's voluntary accreditation scheme would need to address these barriers before more practitioners would apply.

Effect of day time climatic conditions associated with different 2,4-D formulations on spray deposition and weed control.

The aim of this study was to evaluate the effect of time of the day and their associated climatic conditions on spray deposition of two 2,4-D formulations, as well as the influence on weed control. The experiment was installed in the field in complete randomized design. Treatments were arranged in factorial design 8 × 2, with 20 repetitions. First factor corresponded to different application time (1:00, 4:00, 7:00, 10:00, 13:00, 16:00, 19:00, and 22:00) with their respective climatic conditions. The second factor consisted of two formulations of 2,4-D applied at 776 g a.e. ha-1 (2,4-D amine and 2,4-D choline salt with Colex-D™ Technology) + glyphosate (816 g a.e. ha-1). There was more spray deposition when 2,4-D choline formulation was used, and such differences were more evident for applications performed under adverse climatic conditions. More spray deposition was found in applications performed at times of day with more favorable temperature and humidity of the air conditions. Only the initial control of the evaluated species was affected by the time of application.

Inertial wearables as pragmatic tools in dementia.

Dementia is a critically important issue due to its wide impact on health services as well as its personal and societal costs. Limitations exist for current dementia protocols, and there are calls to introduce modern technology that facilitates the addition of digital biomarkers to routine clinical practice. Wearable technology (wearables) are nearly ubiquitous in everyday life, gathering discrete and continuous digital data on habitual activities, but their utility in modern medicine remains low. Due to advances in data analytics, wearables are now commonly discussed as pragmatic tools to aid the diagnosis and treatment of a range of neurological disorders. Inertial sensor-based wearables are one such technology; they offer a low-cost approach to quantify routine movements that are fundamental to normal activities of daily living, most notably postural control and gait. Here, we provide a narrative review of how wearables are providing useful postural control and gait data to facilitate the capture of digital markers to aid dementia research. We outline the history of wearables, from their humble beginnings to their current use beyond the clinic, and explore their integration into modern systems, as well as the ongoing standardisation and regulatory efforts to integrate their use in clinical trials.
