The EkoSonic endovascular system has been cleared by the U.S. Food and Drug Administration for the controlled and selective infusion of physician specified fluids, including thrombolytics, into the peripheral vasculature and the pulmonary arteries. The objective of this study was to explore whether this catheter technology could sustain cavitation nucleated by infused Definity, to support subsequent studies of ultrasound-mediated drug delivery to diseased arteries. The concentration and attenuation spectroscopy of Definity were assayed before and after infusion at 0.3, 2.0 and 4.0 mL/min through the EkoSonic catheter. PCI was used to map and quantify stable and inertial cavitation as a function of Definity concentration in a flow phantom mimicking the porcine femoral artery. The 2.0 mL/min infusion rate yielded the highest surviving Definity concentration and acoustic attenuation. Cavitation was sustained throughout each 15 ms ultrasound pulse, as well as throughout the 3 min infusion. These results demonstrate a potential pathway to use cavitation nucleation to promote drug delivery with the EkoSonic endovascular system. 相似文献

We present a case of a 22-year-old female with nasal collapse secondary to Wegener's Granulomatosis who has benefited from Restylane® injection use to improve cosmesis whilst awaiting formal nasal reconstruction. There are several publications in the otolaryngology and plastic and reconstructive surgery literature in the United States literature which describe this technique1 but we are not aware of any similar publications in the UK literature. 相似文献

Children who have a parent in prison are a vulnerable group. Research suggests that such children experience a range of poor outcomes in relation to well-being, education and relationships. These outcomes are mediated by a range of factors including contact with the incarcerated parent. Similarly, prisoners who maintain contact with their families are less likely to reoffend. Evidence to support the importance of the prison system recognising and helping to maintain parenting roles for parents in prison is beginning to emerge, and this investigation sought to investigate fathers' views of an innovative parenting intervention implemented in Her Majesty's Prison Maghaberry centred around the Being a Dad programme. Eighteen fathers completed the programme. Data collected after participation indicated that fathers reported a range of positive outcomes including improved understanding of child behaviour and development and improved communication quality. Implications for further parenting support within the prison population are discussed. 相似文献

Background: Paradigms which emphasize the social determinants of health and client self-management, and approaches which promote health behavior change, are rarely operationalized within rehabilitation settings. The aim of this study was to investigate the processes required for this model of care change within an existing allied health community rehabilitation service. Methods: The service change program consisted of training elements in the areas of the social determinants of health, client self-management and health behavior change techniques as well as associated operational changes to reflect this paradigm shift. Results: The training packages implemented appear to have improved staff knowledge and skills within these socio-behavioral areas. Clinicians self-reported improvement with client care; however, these changes were not reflected in the chart audit. Conclusions: Clinician training is required to build both knowledge and skills in the areas of the social determinants of health, client self-management and health behavior change principles. In addition, clinicians should be equipped with frameworks to assist with operationalizing these principles. 相似文献

Women’s ability to reproduce is restricted by menarche and menopause. First children are, however, not typically born until some years after the onset of puberty. Other factors therefore contribute towards this delay. In this context, women’s hips do not reach full adult form until they are in their mid-20s. Therefore, physiological and morphological factors appear to determine an optimum age-range for reproduction. The following studies were conducted in order to investigate this hypothesis. Study 1 asked nulliparous women questions about ages at which particular life events related to reproduction should ideally occur. This revealed their preferred age at birth of first child to be approximately 27 years old. Study 2 replicated these findings and further showed that women with children actually had their first child at a very similar age (27.93 [±0.79]). Findings from Study 3 were also remarkably consistent (28.15 [±0.39]). Study 4 examined the 1901 UK Census record and incorporated an analysis of the influence of wealth. Middle class women were on average 24.88 (±0.22) years old at the birth of their first child. Poor women were on average 23.50 (±0.20) years old. These figures at least approximate to findings from Studies 1–3, which is noteworthy given that modern contraceptive methods were not widely available at the time. It is concluded that female strategies to delay giving birth to their first child until they are of an age that approaches or coincides with their full hip maturation are enduring across time. 相似文献
