Abstract
The release of metformin, a drug used in the treatment of cancer and diabetes, from poly(2-hydroxyethyl methacrylate), pHEMA, hydrogel-based microneedle patches is demonstrated in vitro. Tuning the composition of the pHEMA hydrogels enables preparation of robust microneedle patches with mechanical properties such that they would penetrate skin (insertion force of a single microneedle to be ≈40 N). Swelling experiments conducted at 20, 35, and 60 °C show temperature-dependent degrees of swelling and diffusion kinetics. Drug release from the pHEMA hydrogel-based microneedles is fitted to various models (e.g., zero order, first order, second order). Such pHEMA microneedles have potential application for transdermal delivery of metformin for the treatment of aging, cancer, diabetes, etc.

Abstract
Cytokine abnormalities have been described previously in dogs with varied immune mediated and inflammatory conditions such as IMHA and sepsis. The purpose of this study was to establish references ranges for cytokine levels in dogs and to compare cytokine levels in normal dogs and dogs with two common inflammatory diseases (sepsis and IMHA). We hypothesized that cytokine response profiles in dogs with sepsis would be significantly different from those in dogs with IMHA due to the very different etiologies of the two diseases. Concentrations of 14 different cytokines in serum were measured and values grouped according to cytokine function. Serum from clinically normal dogs was used to establish cytokine concentration reference ranges. Rank values for each of the 4 cytokine groups were then compared statistically between healthy control, septic and IMHA dogs. This analysis revealed differences in cytokine groups between dogs with sepsis and IMHA when compared to healthy control dogs but no difference between dogs with either of these conditions. In conclustion, dogs in the early stage of sepsis and IMHA have similar circulating cytokines despite different etiologies suggesting activation of common immunologic pathways. This may have implications for immunotherapy of immune mediated diseases in dogs of varying etiology.

Abstract
The 24th annual symposium of the International Isotope Society's United Kingdom Group took place at the Møller Centre, Churchill College, Cambridge, UK on Friday 6th November 2015. The meeting was attended by 77 delegates from academia and industry, the life sciences, chemical, radiochemical and scientific instrument suppliers. Delegates were welcomed by Dr Ken Lawrie (GlaxoSmithKline, UK, chair of the IIS UK group). The subsequent scientific programme consisted of oral presentations, short 'flash' presentations in association with particular posters and poster presentations. The scientific areas covered included isotopic synthesis, regulatory issues, applications of labelled compounds in imaging, isotopic separation and novel chemistry with potential implications for isotopic synthesis. Both short-lived and long-lived isotopes were represented, as were stable isotopes. The symposium was divided into a morning session chaired by Dr Rebekka Hueting (University of Oxford, UK) and afternoon sessions chaired by Dr Sofia Pascu (University of Bath, UK) and by Dr Alan Dowling (Syngenta, UK). The UK meeting concluded with remarks from Dr Ken Lawrie (GlaxoSmithKline, UK).

Abstract
INTRODUCTION Care farms, where all or part of the farm is used for therapeutic purposes, show much potential for improving the health and well-being of a range of disadvantaged groups. Studies to date have been qualitative or observational, with limited empirical evidence of the effectiveness of care farms in improving health and well-being. Understanding the underlying mechanisms that lead to improvements for different disadvantaged groups is a further gap in the evidence. Participants in this study are offenders serving community orders. Their low socioeconomic status and poor health outcomes relative to the general population exemplifies disadvantage. METHODS AND ANALYSIS This paper describes the protocol of a study to understand the impacts of care farms and to pilot the design and tools for a study to assess cost-effectiveness of care farms in improving the quality of life of offenders. As a pilot study, no power calculation has been conducted. However, 150 offenders serving community sentences on care farms and 150 on other probation locations (eg, litter picking, painting) will be recruited over a 1-year period. Changes in quality of life, measured by Clinical Outcome in Routine Evaluation-Outcome Measure, health and reconvictions of offenders at care farms compared to other probation locations will be analysed to inform the sample size calculation for the follow on study. The feasibility of recruitment, retention, collecting cost data and modelling cost-effectiveness will also be assessed. The study will use qualitative methods to explore the experiences of offenders attending care farms and perceptions of probation and care farm staff on the processes and impacts of the intervention. ETHICS AND DISSEMINATION Findings will be published and inform development of a natural experiment and will be disseminated to probation services, care farms and academics. University of Leeds Ethical Review Board approved: SoMREC/13/014. National Offender Management Service (NOMS) approved: 2013-257.

Abstract
OBJECTIVE To describe the clinical presentation and resultant metabolic disturbances following retroperitoneal administration of hyperphosphate enemas in alpaca crias. CASE OR SERIES SUMMARY Two crias presented to the Colorado State University Veterinary Teaching Hospital after inadvertent transvaginal retroperitoneal hyperphosphate enema administration. The first cria developed an acute onset of neurologic signs, severe hypernatremia, and died soon after presentation. The second cria developed severe hyperphosphatemia, hypocalcemia, and acidemia. The metabolic derangements normalized within 24 hours of intensive treatment with calcium supplementation and IV crystalloid fluid diuresis. The cria was discharged after 1 week in the hospital. NEW OR UNIQUE INFORMATION PROVIDED This report provides a description of electrolyte disturbances secondary to inadvertent transvaginal retroperitoneal administration of hyperphosphate enemas in 2 crias and attendant clinical signs of these disturbances. Management of hyperphosphatemia and hypocalcemia in 1 cria via aggressive fluid therapy with calcium supplementation led to a rapid and sustained normalization of phosphorus, calcium, and acid-base balance.

Abstract
PURPOSE This study examines the predictors of breast cancer screening participation in a panel study of African American women over age 40. We examine the effect of depression, age, beliefs and concerns about breast cancer and its risk, communication with social networks regarding screening, marital status, participation in religious organizations, breast cancer family history, and participation in a breast cancer education program. METHODS Participants were recruited from 30 African American churches, two low-income housing projects, and from a health fair at a historically African American University (N = 364). Participants were interviewed upon recruitment, and three months later. Multinomial logistic regression models are estimated to assess the relative impact of covariates on the odds of getting a mammogram while controlling for other factors. We also assess predicted probabilities of screening at specific levels of covariates. RESULTS We find that age, marriage, an educational intervention, talking with friends, and believing that early detection can lead to cure had a positive impact on getting a mammogram between T1 and T2. In contrast, depression significantly reduces the odds of getting a mammogram. Family histories of breast cancer and church participation have no effect on rates of mammography net of other factors.

Abstract
We have developed an attributable cost model for a city-based telecare scheme involving 11,618 community alarm users. The equipment was assumed to cost 500 Pounds-1000 Pounds per installation, compared with 175 Pounds for the current system. Because of the significant additional capital cost of the proposed system, it would be necessary to borrow to finance it. For example, if the home equipment cost 500 Pounds per unit, an additional 2.2 million Pounds would be required. Nonetheless, it would be possible to achieve a return on the investment after 10 years. The principal savings would arise from reduced hospital bed costs and reduced residential care. The model suggests that the financial benefits of the proposed system would occur in the ratio of 4% to the local authority housing department, 43% to the National Health Service and 53% to the residential care provider.

Abstract
Previous surveys have suggested that community alarm users are in general satisfied with the service provided. However, there is also evidence that users would like additional options that could be provided by a telecare system. Inner-city users of community alarms were consulted about their current systems and the extension of these to incorporate telecare options. The users lived in 160 homes in three multistorey apartment blocks. The average age of the 176 users surveyed was 76 years. Seventy-seven per cent of users were interested in automatic fall detection, 68% in lifestyle monitoring, 57% in telemedicine and 46% in videoconferencing. Nineteen of those interviewed (11%) did not want any of the suggested enhancements. The survey showed that elderly people are not technophobes, since 58% possessed either a microwave oven or a video-recorder, and also showed that the majority were prepared to accept new technologies that would support their independence.

Abstract
As the number of elderly people in society increases, the use of technology to support the care system is being examined. However, there is no agreed model of a technology-based health-care system that fully integrates the technical and social aspects to meet the needs of both clients and care providers. This paper examines a possible model from the perspective of both the client and the service provider, and estimates the costs, and hence the potential savings, associated with the introduction of a health-care system based on this model. Cost data are presented in the context of an installation as might be anticipated within a city such as Birmingham, UK. Installation costs of an advanced telecare system would be higher than the set-up costs of conventional systems. Expected savings in control centre costs and emergency services costs would be small. However, a reduction in the average annual length of hospital stay by one day and a reduction in the proportion of elderly people being treated in hospital from 32.4% to 32.0%, directly as a result of the use of advanced telecare, would produce significant savings. A financing scheme with a 5-year or 10-year repayment period would then be financially viable for a 10,000-home advanced telecare system.
