Estimated Glomerular Filtration Rate Decline as a Predictor of Dialysis in Kidney Transplant Recipients

BACKGROUND: It is now common for individuals to require dialysis following the failure of a kidney transplant. Management of complications and preparation for dialysis are suboptimal in this group. To aid planning, it is desirable to estimate the time to dialysis requirement. The rate of decline in the estimated glomerular filtration rate (eGFR) may be used to this end.

METHODS: This study compared the rate of eGFR decline prior to dialysis commencement between individuals with failing transplants and transplant-naïve patients. The rate of eGFR decline was also compared between transplant recipients with and without graft failure. eGFR was calculated using the four-variable MDRD equation with rate of decline calculated by least squares linear regression.

RESULTS: The annual rate of eGFR decline in incident dialysis patients with graft failure exceeded that of the transplant-naïve incident dialysis patients. In the transplant cohort, the mean annual rate of eGFR decline prior to graft failure was 7.3 ml/min/1.73 m(2) compared to 4.8 ml/min/1.73 m(2) in the transplant-naïve group (p < 0.001) and 0.35 ml/min/1.73 m(2) in recipients without graft failure (p < 0.001). Factors associated with eGFR decline were recipient age, decade of transplantation, HLA mismatch and histological evidence of chronic immunological injury.

CONCLUSIONS: Individuals with graft failure have a rapid decline in eGFR prior to dialysis commencement. To improve outcomes, dialysis planning and management of chronic kidney disease complications should be initiated earlier than in the transplant-naïve population.

Combining and integrating life /social sciences and citizen trainers in Nurse Education - a N. Ireland initiative

Before commencement of the academic year 2012/2013 the social sciences, public health and the biomedical sciences were taught to separate modules. This reinforced the idea off separate disciplines certainly for some of the younger students and a failure to appreciate the interconnectedness (whole person) perspective on health; separately modules taught and assessed in separate silos. There was limited understanding by the lecturers of the other areas that they were not teaching to -reflecting perhaps a dis-coordinated approach to health sciences (Mason and Whitehead 2003). As a result of significant discussion and interdisciplinary negotiation the life, social sciences public health/ health education were drawn together in the one module for the academic year 2012/13. The module provides the undergraduate students with an introduction to an understanding of Life Sciences, psychology, sociology and public health and their contribution within the context of nursing and midwifery. Each week’s teaching seeks to reflect against the other module delivered in first year - addressing clinical skills. The teaching is developing innovative e-learning approaches, including the use of a virtual community. The intention is to provide the student with a more integrated understanding and teaching to the individual’s health and to health within a social context (Lin 2001; Iles- Shih 2011). The focus is on health promotion rather than disease management. The module runs in three phases across the student’s first-year and teachers to the field of adult mental health, learning disability, children’s nursing and the midwifery students -progressively building on the student’s clinical experience. The predominant focus of the module remains on health and reflecting aspects of life and social life within N. Ireland. One of the particular areas of interest and an area of particular sensitivity is engaging the students to the context of the Northern Ireland civil unrest (the Troubles); this involves a co-educational initiative with service users, only previously attempted with social work students (Duffy 2012). The service users are represented by WAVE an organisation offering care and support to bereaved, traumatised or injured as a result of the violent civil conflict `the Troubles’. The `Troubles’ had ranged over an extended period and apart from the more evident and visual impact of death and injury, the community is marked by a disproportionate level of civil unrest, the extremes of bereavement, imprisonment, displacement antisocial behaviour and family dysfunction (Coulter et al. 2012). As co-educators with the School of Nursing and Midwifery, WAVE deliver a core lecture (augmented by online material), then followed by tutorials. The tutorials are substantially led by those who had been involved with and experienced loss and trauma as a result of the conflict (Health Service users) as `citizen trainers’ and provide an opportunity for them to share their experience and their recollection of personal interaction with nursing and midwifery students; in improving their understanding of the impact of `The Troubles’ on patients and clients affected by the events (Coulter et al. 2012) and to help better provide a quality of care cognisant of the particular needs of those affected by `the Troubles’ in N.Ireland. This approach is relatively unique to nursing in N. Ireland in that it involves many of those directly involved with and injured by the `Troubles’ as `citizen trainers’ and clearly reflects the School’s policy of progressively engaging with users and carers of nursing and midwifery services as co-educators to students (Repper & Breeze 2006). Only now could perhaps such a sensitive level of training to student nurses and midwives be delivered across communities with potential educative lessons for other communities experiencing significant civil unrest and sectarian conflict.

Pre-Radiotherapy Dental Assessment of Head and Neck Oncology Patients: An Audit.

Objectives: Approximately 300 people are diagnosed with Head and Neck cancer annually in Northern Ireland. The management may include treatment by surgery or by chemotherapy and radiotherapy,
or a combination of modalities. Patients whose oral cavity, teeth, salivary glands and jaws that
will be affected by treatment, particularly radiotherapy should have a pre-treatment assessment. This should be done as early as possible to maximise the time available for dental management. However, this can be challenging owing to the complexities of cancer diagnosis, treatment planning and multidisciplinary management. At the Belfast Dental Hospital, a number of patients were referred post- radiotherapy with complications after not having received a pre-treatment assessment. The referrals for pre- treatment dental assessment were also late in patients’ multidisciplinary journey, limiting the time period
for dental input. The purpose of this audit was to examine the time period between dental assessment and commencement of radiotherapy and whether this was an adequate time frame for dental management. This audit will also examine the dental diseases present and the treatments required pre-radiotherapy. Methods: Data for this audit was collected over 4 months in 2012
by analysing the dental charts and referrals of new patients who were referred to and attended the dental head and neck oncology clinic. A standardised referral pro-forma was introduced from September 2013 to improve the referral process.
A re-audit was conducted over 4 months in 2014. Data was collected similarly as previous. The time period between dental assessment and commencement of radiotherapy was examined. The presence of dental disease and subsequent treatments required were also noted.
Results: 63 new patients were examined in the dental head and neck oncology clinic over 4 months in 2012. 48 (76.2%) were examined pre-radiotherapy. The average length of time between dental assessment and radiotherapy commencement was 11 days. A new standardised referral pro-forma was introduced in 2013. In the re-audit, 65 new patients were seen over 4 months in 2014.
60 (92.3%) patients were examined pre-radiotherapy. The average length of time between dental assessment and radiotherapy commencement was 18 days.
Conclusion: Given the high prevalence of pre-existing dental disease amongst head and neck cancer patients, prompt dental assessment and treatment is vital. Efforts aimed at improving the care pathway are on-going through the implementation of a mandatory referral pro-forma and a dedicated assessment clinic.

From 'trailing wives' to the emergence of a 'trailing husbands' phenomenon: Retirement migration to rural areas

Migration and gender studies have focused on economically active heterogeneous couples and traditionally highlight a dominant male role in migration decision-making. The female partner is commonly portrayed as a 'trailing wife' or 'trailing mother' with the move found to have a negative effect on her employment prospects. Much less is known about if or how the balance of power shifts between husbands and wives when employment or career-motivated moves are removed from the decision-making process. This is analysed with reference to retirement migration to rural areas of the UK and involved interviews with both partners present. For this cohort of retired couples, and in common with the literature, migration during economically active life course stages demonstrates strong 'trailing wife' and 'trailing mother' tendencies. The male's decision to retire signalled the commencement of a retirement life course stage for the couple. However, in contrast to the earlier male dominated decision-making, retirement migration saw the emergence of a 'trailing husband' phenomenon. Wives appear to adapt most successfully to the new rural environment while many husbands found it difficult to adjust (at least initially) to the multiple life changes: moving from largely urban areas to a rural setting alongside exiting the workforce. The findings suggest that the role of leader/ follower changed during the course of these couples' lives together and in relation to their reasons for moving.

Cet autre qui me regarde. Phénoménologie de la mémoire et temps eschatologique dans Le Premier Jardin et Oh les beaux jours

Alors que Les fous de Bassan s’attachait à mettre en scène une Amérique métonymique tournée vers sa fin, tout se passe comme si Le premier jardin visait pour sa part à lester cette Amérique incertaine et eschatologique par l’anamnèse de son commencement, qui, chez Anne Hébert, prend le plus souvent la forme d’un re-commencement. Il s’agira ici d’interroger le dispositif temporel mis en fiction dans le roman, notamment par l’entremise d’une lecture de la pièce Oh les beaux jours et de sa temporalité figée d’après-coup. À travers cette analyse de la temporalité, on voudra également mettre en relief l’instrumentalisation de l’histoire collective par le sujet, qui cherche ainsi à se prémunir de sa propre mémoire, constamment mise à distance au sein du roman.

Application of Decision-Making Theory to the Regulation of Muscular Work Rate During Self-Paced Competitive Endurance Activity.

Successful participation in competitive endurance activities requires continual regulation of muscular work rate in order to maximise physiological performance capacities, meaning that individuals must make numerous decisions with regards to the muscular work rate selected at any point in time. Decisions relating to the setting of appropriate goals and the overall strategic approach to be utilised are made prior to the commencement of an event, whereas tactical decisions are made during the event itself. This review examines current theories of decision-making in an attempt to explain the manner in which regulation of muscular work is achieved during athletic activity. We describe rational and heuristic theories, and relate these to current models of regulatory processes during self-paced exercise in an attempt to explain observations made in both laboratory and competitive environments. Additionally, we use rational and heuristic theories in an attempt to explain the influence of the presence of direct competitors on the quality of the decisions made during these activities. We hypothesise that although both rational and heuristic models can plausibly explain many observed behaviours in competitive endurance activities, the complexity of the environment in which such activities occur would imply that effective rational decision-making is unlikely. However, at present, many proposed models of the regulatory process share similarities with rational models. We suggest enhanced understanding of the decision-making process during self-paced activities is crucial in order to improve the ability to understand regulation of performance and performance outcomes during athletic activity.

Role of surgery in the management of brain arteriovenous malformations: prospective cohort study.

BACKGROUND AND PURPOSE: Management of brain arteriovenous malformation (bAVM) is controversial. We have analyzed the largest surgical bAVM cohort for outcome. METHODS: Both operated and nonoperated cases were included for analysis. A total of 779 patients with bAVMs were consecutively enrolled between 1989 and 2014. Initial management recommendations were recorded before commencement of treatment. Surgical outcome was prospectively recorded and outcomes assigned at the last follow-up visit using modified Rankin Scale. First, a sensitivity analyses was performed to select a subset of the entire cohort for which the results of surgery could be generalized. Second, from this subset, variables were analyzed for risk of deficit or near miss (intraoperative hemorrhage requiring blood transfusion of ≥2.5 L, hemorrhage in resection bed requiring reoperation, and hemorrhage associated with either digital subtraction angiography or embolization). RESULTS: A total of 7.7% of patients with Spetzler-Ponce classes A and B bAVM had an adverse outcome from surgery leading to a modified Rankin Scale >1. Sensitivity analyses that demonstrated outcome results were not subject to selection bias for Spetzler-Ponce classes A and B bAVMs. Risk factors for adverse outcomes from surgery for these bAVMs include size, presence of deep venous drainage, and eloquent location. Preoperative embolization did not affect the risk of perioperative hemorrhage. CONCLUSIONS: Most of the ruptured and unruptured low and middle-grade bAVMs (Spetzler-Ponce A and B) can be surgically treated with a low risk of permanent morbidity and a high likelihood of preventing future hemorrhage. Our results do not apply to Spetzler-Ponce C bAVMs.
