Selected AbstractsFrom retirement village to residential aged care: what older people and their families sayHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 1 2007Julianne Cheek PhD BEd DipT Abstract The majority of older Australians, some of whom live in retirement villages, wish to remain living in their own home, receiving care in the community when their health and/or other circumstances change. Current statistics show that 3.7% of people aged 65 years and over live in a retirement village in Australia. However, residential aged care will still be required for some highly dependent members of the older population. This qualitative Australian study examined the transition into residential care from one form of community housing, the retirement village. In-depth interviews with 33 older people and 48 family members were conducted to illuminate the key issues and factors which influence the move of older people from retirement villages to residential aged care. Analysis of the data revealed the move to be influenced by: health-related crises; the creation of doubt as to ability to cope in the retirement village; the need for more or different care or support services; the desire for independence; assumptions about being able to move into the residential aged care facility co-located with the retirement village; availability of a place; navigating the system; and desirable aspects of a residential aged care facility. The findings of the study provide a description of the transition process from the perspectives of those directly affected, and contribute to the development of best practice in the provision of support to residents living in retirement villages and the community in general. [source] Regional variability in secondary remodeling within long bone cortices of catarrhine primates: the influence of bone growth historyJOURNAL OF ANATOMY, Issue 3 2008Shannon C. McFarlin Abstract Secondary intracortical remodeling of bone varies considerably among and within vertebrate skeletons. Although prior research has shed important light on its biomechanical significance, factors accounting for this variability remain poorly understood. We examined regional patterning of secondary osteonal bone in an ontogenetic series of wild-collected primates, at the midshaft femur and humerus of Chlorocebus (Cercopithecus) aethiops (n = 32) and Hylobates lar (n = 28), and the midshaft femur of Pan troglodytes (n = 12). Our major objectives were: 1) to determine whether secondary osteonal bone exhibits significant regional patterning across inner, mid-cortical and outer circumferential cortical rings within cross-sections; and if so, 2) to consider the manner in which this regional patterning may reflect the influence of relative tissue age and other circumstances of bone growth. Using same field-of-view images of 100-µm-thick cross-sections acquired in brightfield and circularly polarized light microscopy, we quantified the percent area of secondary osteonal bone (%HAV) for whole cross-sections and across the three circumferential rings within cross-sections. We expected bone areas with inner and middle rings to exhibit higher %HAV than the outer cortical ring within cross-sections, the latter comprising tissues of more recent depositional history. Observations of primary bone microstructural development provided an additional context in which to evaluate regional patterning of intracortical remodeling. Results demonstrated significant regional variability in %HAV within all skeletal sites. As predicted,%HAV was usually lowest in the outer cortical ring within cross-sections. However, regional patterning across inner vs. mid-cortical rings showed a more variable pattern across taxa, age classes, and skeletal sites examined. Observations of primary bone microstructure revealed that the distribution of endosteally deposited bone had an important influence on the patterning of secondary osteonal bone across rings. Further, when present, endosteal compacted coarse cancellous bone always exhibited some evidence of intracortical remodeling, even in those skeletal sites exhibiting comparatively low %HAV overall. These results suggest that future studies should consider the local developmental origin of bone regions undergoing secondary remodeling later in life, for an improved understanding of the manner in which developmental and mechanical factors may interact to produce the taxonomic and intraskeletal patterning of secondary bone remodelling in adults. [source] Should it be legal to assist suicide?JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 2 2010Harry Lesser BA B.Phil (Oxon) Abstract This paper argues that because it is a matter of dispute whether to assist suicide is ever morally right, the question whether assisted suicide should be legal should be decided independently of the moral issue and with reference to whether to assist suicide is genuinely to carry out the wishes of the person requesting it. It is then argued that it is possible to devise a set of criteria, based on those used in the Netherlands with regard to euthanasia, which would allow assisted suicide when the request is reasonable and genuine, but keep it illegal under other circumstances. It is further argued that there is no evidence that legalizing assisted suicide will lead us down the slippery slope to involuntary euthanasia. Finally, the question is raised to whether these assisted suicides should be legalized or, as at the moment in the UK, simply not prosecuted, but, as is about to happen, with the criteria for non-prosecution made explicit. It is suggested that, although it is in some ways both irrational and unjust, non-prosecution is politically easier to achieve and also more cautious as a first move. [source] Assessment of tissue redox status using metabolic responsive contrast agents and magnetic resonance imagingJOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 8 2008Fuminori Hyodo Regulation of tissue redox status is important to maintain normal physiological conditions in the living body. Disruption of redox homoeostasis may lead to oxidative stress and can induce many pathological conditions such as cancer, neurological disorders and ageing. Therefore, imaging of tissue redox status could have clinical applications. Redox imaging employing magnetic resonance imaging (MRI) with nitroxides as cell-permeable redox-sensitive contrast agents has been used for non-invasive monitoring of tissue redox status in animal models. The redox imaging applications of nitroxide electron paramagnetic resonance imaging (EPRI) and MRI are reviewed here, with a focus on application of tumour redox status monitoring. While particular emphasis has been placed on differences in the redox status in tumours compared to selected normal tissues, the technique possesses the potential to have broad applications to the study of other disease states, inflammatory processes and other circumstances where oxidative stress is implicated. [source] Ordained Ministry in Maori Christianity, 1853,1900JOURNAL OF RELIGIOUS HISTORY, Issue 1 2003Raeburn Lange From 1853 an ordained clergy emerged in the Protestant (but not the Catholic) churches founded by missionary organisations in New Zealand in the first half of the nineteenth century. Ordained indigenous ministers succeeded and largely superseded an earlier large force of lay "teachers." Although the Maori churches might in other circumstances have been seen as progressing towards self,reliance and autonomy, the colonial context of the second half of the nineteenth century confined them and their clergy to a restricted place in the ecclesiastical life of New Zealand. The transition from "teachers" to "ministers" in the Church Missionary Society (Anglican) and Wesleyan missions is examined, and a study is made of the place of indigenous ministers in the Maori Anglican and Wesleyan churches, the Mormon church, and the Maori religious movements such as Ringatu. [source] Individual female clutch identification through yolk protein electrophoresis in the communally breeding guira cuckoo (Guira guira)MOLECULAR ECOLOGY, Issue 11 2002Mariana O. Cariello Abstract Avian communal breeding systems generate alternative behavioural strategies for females, resulting in differences in reproductive success. Identifying eggs of different females in such systems is problematic, however, due to egg destruction before incubation, difficulty of capturing adults, and/or inaccuracy of egg identification based on egg morphometry. Here, we describe a technique that uses electrophoresis of yolk proteins to determine egg ownership, which we applied to communally breeding guira cuckoos (Guira guira). Validation of the method included identical yolk protein banding patterns in all eggs of the same female, but different patterns in eggs of different females in budgerigars (Melopsittacus undulatus), and identical patterns in yolk follicles of the same females in guira cuckoos. We applied the protocol to 195 guira cuckoo eggs from 34 joint nests in 2 years. All multiple guira cuckoo eggs laid on the same day in single nests had distinct banding patterns of yolk proteins, practically eliminating the possibility of more than one female being represented by the same pattern. Some identical banding patterns were repeated in different days within a nesting bout, indicating that some females laid several eggs in shared nests. Identical patterns occasionally occurred in renestings of groups, indicating that some females lay eggs in consecutive nestings. Yolk protein electrophoresis is a useful tool to identify egg maternity in other circumstances, such as polygynous mating systems with joint nests and intraspecific parasitism. Additionally, it is an alternative method for species where electrophoresis of egg white proteins does not show sufficient polymorphism. [source] Angiogenesis in the Caprine Caruncles in Non-Pregnant and Pregnant Normal and Swainsonine-Treated DoesTHE ANATOMICAL RECORD : ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY, Issue 7 2007S.A. Hafez Abstract Microvascular corrosion casts of caruncles from non-pregnant and pregnant doe goats at 4, 7, 10, 13, 16, and 18 weeks were examined with scanning electron microscopy. The internal convex surface of the caruncles of non-pregnant does was covered with capillary meshes of regular diameter and form, without crypts. As pregnancy advanced the complexity of the vasculature increased: at 4 weeks the surface showed a pattern of ridges separated by troughs. At later stages, branches of radial arteries penetrated the periphery forming an extensive mesh of capillaries on the concave surface. Capillary diameters increased significantly during pregnancy, especially after 4 weeks, when large flattened sinusoids formed. These sinusoids had a great deal of surface area for potential contact with the fetal component. The caprine placenta is usually considered to have increased interhemal distance compared with endotheliochorial and hemochorial types: our results suggest that the very extensive development of sinusoids and crypts may compensate for any negative consequences of the placental architecture. Placental angiogenesis, which is physiologically normal, may serve as a general model of this process in other circumstances, such as tumor. The effect of swainsonine (active compound of locoweed and a potential anticancer drug) on vascular development showed no differences in sinusoidal diameters at 7 weeks, but a decrease in capillary density was noted. Swainsonine caused a great distortion to the vasculature at 18 weeks. The effects of this compound on the vascular development lend credibility to its potential as an anticancer agent.

[source] Amiodarone for Atrial Fibrillation Following Cardiac Surgery: Development of Clinical Practice Guidelines at a University HospitalCLINICAL CARDIOLOGY, Issue 1 2008Pharm D., Ujjaini Khanderia M.S. Abstract Atrial fibrillation (AF) usually develops within the first 72 h following cardiac surgery, and is often self-limiting. Within 48 h of acute onset of symptoms, approximately 50% of patients spontaneously convert to normal sinus rhythm. Thus, the relative risks and benefits of therapy must be carefully considered. The etiology of AF following cardiac surgery is similar to that in non-surgical patients except that pericardial inflammation and increased adrenergic tone play an increasingly important role. Further, AF after surgery may be associated with transient risk factors that resolve as the patient moves out from surgery, and the condition is less likely to recur compared to AF arising in other circumstances. Immediate heart rate control is important in preventing ischemia, tachycardia-induced cardiomyopathy, and left ventricular dilatation. At our institution, amiodarone is frequently used as a first-line drug for treating AF after cardiac surgery. Inconsistent prescribing practices, variable dosage regimens, and a lack of consensus regarding the appropriate use of amiodarone prompted the need for developing practice guidelines. Multidisciplinary collaboration between the departments of cardiac surgery, pharmacy, and anesthesiology led to the development of a protocol for postoperative AF. We review the clinical evidence from published trials and discuss our guidelines, defining amiodarone use for AF in the cardiac surgery setting. Copyright © 2007 Wiley Periodicals, Inc.
