RESUMEN

Imaging plays a crucial role in evaluating paediatric patients with non-traumatic head and neck lesions in an emergency setting because clinical manifestations of these entities can overlap. For this reason, radiologists must be familiar with the clinical and imaging findings of prevalent paediatric head and neck emergencies. In this review, we present techniques and imaging clues for common complications of pathological processes in the paediatric head and neck, with a focus on the clinical scenario as a starting point for the radiologic approach.

RESUMEN

BACKGROUND: Predictive models based on radiomics features are novel, highly promising approaches for gynaecological oncology. Here, we wish to assess the prognostic value of the newly discovered Radiomic Prognostic Vector (RPV) in an independent cohort of high-grade serous ovarian cancer (HGSOC) patients, treated within a Centre of Excellence, thus avoiding any bias in treatment quality. METHODS: RPV was calculated using standardised algorithms following segmentation of routine preoperative imaging of patients (n = 323) who underwent upfront debulking surgery (01/2011-07/2018). RPV was correlated with operability, survival and adjusted for well-established prognostic factors (age, postoperative residual disease, stage), and compared to previous validation models. RESULTS: The distribution of low, medium and high RPV scores was 54.2% (n = 175), 33.4% (n = 108) and 12.4% (n = 40) across the cohort, respectively. High RPV scores independently associated with significantly worse progression-free survival (PFS) (HR = 1.69; 95% CI:1.06-2.71; P = 0.038), even after adjusting for stage, age, performance status and residual disease. Moreover, lower RPV was significantly associated with total macroscopic tumour clearance (OR = 2.02; 95% CI:1.56-2.62; P = 0.00647). CONCLUSIONS: RPV was validated to independently identify those HGSOC patients who will not be operated tumour-free in an optimal setting, and those who will relapse early despite complete tumour clearance upfront. Further prospective, multicentre trials with a translational aspect are warranted for the incorporation of this radiomics approach into clinical routine.

RESUMEN

BACKGROUND: Qualitative studies of participants' experiences in randomised clinical trials (RCTs) suggest that the psychosocial context of treatment in RCTs may be quite different to the psychosocial context of treatment in usual practice. This is important, as the psychosocial context of treatment is known to influence patient outcomes in chronic illness. Few studies have directly compared the psychosocial context of treatment across RCTs and usual practice. In this study, we explored differences in psychosocial context between RCT and usual practice settings, using acupuncture as our model. METHODS: We undertook a secondary analysis of existing qualitative interviews with 54 patients. 27 were drawn from a study of western and traditional acupuncture in usual practice (for a range of painful conditions). 27 were drawn from a qualitative study nested in an RCT of western acupuncture for osteoarthritis of the hip or knee. We used qualitative analysis software to facilitate an inductive thematic analysis in which we identified three main themes. RESULTS: In usual practice, starting acupuncture was more likely to be embedded in an active and ongoing search for pain relief, whereas in the RCT starting acupuncture was opportunistic. Usual practice patients reported few uncertainties and these had minimal consequences for them. In the RCT, patients experienced considerable uncertainties about their treatment and its effectiveness, and were particularly concerned about whether they were receiving real (or fake) acupuncture. Patients stopped acupuncture only at the end of the fixed course of treatment in the RCT, which was similar to those receiving acupuncture in the public sector National Health Service (NHS). In comparison, private sector patients re-evaluated and re-negotiated treatments particularly when starting to use acupuncture. CONCLUSIONS: Differences in psychosocial context between RCTs and usual practice could reduce the impact of acupuncture in RCT settings and/or lead to under-reporting of benefit by patients in trials. New trial designs that ensure participants' experiences are similar to usual practice should minimise differences in psychosocial context and help attenuate these potentially confounding effects.

RESUMEN

BACKGROUND: The aim of this study was to compare patients' experiences of public and private sector healthcare, using acupuncture as an example. In the UK, acupuncture is popular with patients, is recommended in official guidelines for low back pain, and is available in both the private sector and the public sector (NHS). Consumerism was used as a theoretical framework to explore patients' experiences. METHODS: Semi-structured face-to-face interviews were conducted in 2007-8 with a purposive sample of 27 patients who had recently used acupuncture for painful conditions in the private sector and/or in the NHS. Inductive thematic analysis was used to develop themes that summarised the bulk of the data and provided insights into consumerism in NHS- and private practice-based acupuncture. RESULTS: Five main themes were identified: value for money and willingness to pay; free and fair access; individualised holistic care: feeling cared for; consequences of choice: empowerment and vulnerability; and "just added extras": physical environment. Patients who had received acupuncture in the private sector constructed detailed accounts of the benefits of private care. Patients who had not received acupuncture in the private sector expected minimal differences from NHS care, and those differences were seen as not integral to treatment. The private sector facilitated consumerist behaviour to a greater extent than did the NHS, but private consumers appeared to base their decisions on unreliable and incomplete information. CONCLUSIONS: Patients used and experienced acupuncture differently in the NHS compared to the private sector. Eight different faces of consumerist behaviour were identified, but six were dominant: consumer as chooser, consumer as pragmatist, consumer as patient, consumer as earnest explorer, consumer as victim, and consumer as citizen. The decision to use acupuncture in either the private sector or the NHS was rarely well-informed: NHS and private patients both had misconceptions about acupuncture in the other sector. Future research should evaluate whether the differences we identified in patients' experiences across private and public healthcare are common, whether they translate into significant differences in clinical outcomes, and whether similar faces of consumerism characterise patients' experiences of other interventions in the private and public sectors.
