Purpose: To appraise the application of accepted good practice guidance on public involvement in assistive technology research and to identify its impact on the research team, the public, device and trial design. Methods: Critical reflection and within-project evaluation were undertaken in a case study of the development of a functional electrical stimulation device. Individual and group interviews were undertaken with lay members of a 10 strong study user advisory group and also research team members. Results: Public involvement was seen positively by research team members, who reported a positive impact on device and study designs. The public identified positive impact on confidence, skills, self-esteem, enjoyment, contribution to improving the care of others and opportunities for further involvement in research. A negative impact concerned the challenge of engaging the public in dissemination after the study end. Conclusions: The public were able to impact significantly on the design of an assistive technology device which was made more fit for purpose. Research team attitudes to public involvement were more positive after having witnessed its potential first hand. Within-project evaluation underpins this case study which presents a much needed detailed account of public involvement in assistive technology design research to add to the existing weak evidence base.
- Implications for Rehabilitation
The evidence base for impact of public involvement in rehabilitation technology design is in need of development.
Public involvement in co-design of rehabilitation devices can lead to technologies that are fit for purpose.
Rehabilitation researchers need to consider the merits of active public involvement in research.

The clinical use of conventional ultrasonography (US) in autosomal dominant polycystic kidney disease (ADPKD) is currently limited by reduced diagnostic sensitivity, especially in at-risk subjects younger than 30 years of age. In this single-center prospective study, we compared the diagnostic performance of MRI with that of high-resolution (HR) US in 126 subjects ages 16–40 years born with a 50% risk of ADPKD who underwent both these renal imaging studies and comprehensive PKD1 and PKD2 mutation screening. Concurrently, 45 healthy control subjects without a family history of ADPKD completed the same imaging protocol. We analyzed 110 at-risk subjects whose disease status was unequivocally defined by molecular testing and 45 unaffected healthy control subjects. Using a total of >10 cysts as a test criterion in subjects younger than 30 years of age, we found that MRI provided both a sensitivity and specificity of 100%. Comparison of our results from HR US with those from a previous study of conventional US using the test criterion of a total of three or more cysts found a higher diagnostic sensitivity (approximately 97% versus approximately 82%) with a slightly decreased specificity (approximately 98% versus 100%) in this study. Similar results were obtained in test subjects between the ages of 30 and 40 years old. These results suggest that MRI is highly sensitive and specific for diagnosis of ADPKD. HR US has the potential to rival the diagnostic performance of MRI but is both center- and operator-dependent. 相似文献

Cardiac resynchronization therapy (CRT) is a relatively new therapy for patients with symptomatic heart failure resulting from systolic dysfunction. CRT is achieved by simultaneously pacing both the left and right ventricles. Biventricular pacing resynchronizes the timing of global left ventricular depolarization and improves mechanical contractility and mitral regurgitation. Published clinical trials have demonstrated that CRT results in improved clinical status and lower mortality rate when selected patients with systolic ventricular dysfunction and heart failure are treated with CRT. This advisory identifies appropriate candidates for CRT on the basis of the inclusion criteria and results from the published clinical trials. 相似文献

Tactile discrimination depends on integration of information from the discrete receptive fields (RFs) of peripheral sensory afferents. Because this information is processed over a hierarchy of subcortical nuclei and cortical areas, the integration likely occurs at multiple levels. The current study presents results indicating that neurons across most of the extent of the hand representation in monkey primary somatosensory cortex (area 3b) interact, even when these neurons have separate RFs. We obtained simultaneous recordings by using a 100-electrode array implanted in the hand representation of primary somatosensory cortex of two anesthetized owl monkeys. During a series of 0.5-s skin indentations with single or dual probes, the distance between electrodes from which neurons with synchronized spike times were recorded exceeded 2 mm. The results provide evidence that stimuli on different parts of the hand influence the degree of synchronous firing among a large population of neurons. Because spike synchrony potentiates the activation of commonly targeted neurons, synchronous neural activity in primary somatosensory cortex can contribute to discrimination of complex tactile stimuli. 相似文献

Proportion of Patients With Hypertension Resolution Following Adrenalectomy for Primary Aldosteronism: A Systematic Review and Meta‐Analysis 下载免费PDF全文
Jamie L. Benham MD Maysoon Eldoma MD MBT Bushra Khokhar MSc Derek J. Roberts MD PhD Doreen M. Rabi MD MSc FRCPC Gregory A. Kline MD FRCPC 《Journal of clinical hypertension (Greenwich, Conn.)》2016,18(12):1205-1212
Unilateral primary aldosteronism (PA) is often treated with adrenalectomy, but hypertension resolution rates are variable. A valid estimate of the postoperative normotension rate is necessary to inform the utility of PA testing and treatment. The authors searched MEDLINE In‐Process & Other Non‐Indexed Citations, Embase, and Cochrane Central Register of Controlled Trials. Prospective adult cohort studies with surgically treated PA that reported resolution of hypertension without the aid of medications were included. Among 2620 abstracts identified by the search, 25 studies in the systematic review with data on 1685 patients were investigated. The pooled proportion of normotension following adrenalectomy was 52% (95% confidence interval, 0.44–0.60). Meta‐regression demonstrated a significant negative association between length of follow‐up and proportion of normotension, with normotension dropping by 6.7% per year of follow‐up (coefficient −0.006; 95% confidence interval, −0.01 to 0.002). Overall, approximately half of the patients experienced hypertension resolution, although this outcome may not be durable in all patients.Primary aldosteronism (PA) is defined as a form of drug‐resistant and potentially curable hypertension with evidence of excess aldosterone secretion, suppressed plasma renin activity, and often hypokalemia.1 Initially thought to be rare, PA is the leading cause of secondary hypertension. With increased screening and detection, the incidence of PA among hypertensive patients is currently reported at approximately 10%.2 This syndrome has multiple etiologies, including inherited gene mutations,3 development of autoantibodies,4 and ectopic aberrant functional adrenal receptors.5 The clinical management is guided by the definition of unilateral vs bilateral adrenal involvement. With rare exception, adrenalectomy is reserved for unilateral adrenal disease.The proportion “cured” following adrenalectomy for patients with PA has been reported to range from 0% to 100%.6 However, “cure” is variably defined in the literature. These definitions include normal blood pressure (BP), normal BP without aid of antihypertensive medications, a reduced need for antihypertensive medications, and biochemical normalization, among others. Biochemical normalization of the aldosterone‐renin ratio is likely a necessary part of a definition of “cure.” At this time, however, there is no global consensus on the interpretation of postoperative aldosterone‐renin ratios with the existence of variable assays and cutoffs for even initial diagnosis. Therefore, from the patient''s perspective and in the absence of patient‐level clinical end point data, attainment of medication‐free normotension may be the most uniform and recognizable health benefit of surgical PA treatment. Individually reported results of long‐term resolution of hypertension without antihypertensive medications are between 30% and 70% following adrenalectomy.7 The primary aim of this systematic review and meta‐analysis was to determine the proportion of hypertension resolution without the aid of antihypertensive agents following adrenalectomy in patients with PA. To our knowledge, no previous meta‐analysis has been performed. A secondary objective was to identify patient‐level factors reported to be associated with hypertension resolution in patients managed with adrenalectomy. 相似文献
