English Channel towed sledge seabed images. Phase 2: Analysis of selected tow images

During the 1970s and 1980s, the late Dr Norman Holme undertook extensive towed sledge surveys in the English Channel and some in the Irish Sea. Only a minority of the resulting images were analysed and reported before his death in 1989 but logbooks, video and film material has been archived in the National Marine Biological Library (NMBL) in Plymouth. A study was therefore commissioned by the Joint Nature Conservation Committee and as a part of the Mapping European Seabed Habitats (MESH) project to identify the value of the material archived and the procedure and cost to undertake further work (Phase 1 of the study reported here: Oakley & Hiscock, 2005). Some image analysis was undertaken as a part of Phase 1. Phase 2 (this report) was to further analyse selected images. Having determined in Phase 1 that only the 35 mm photographic transparencies provided sufficient clarity to identify species and biotopes, the tows selected for analysis were ones where 35mm images had been taken. The tows selected for analysis of images were mainly in the vicinity of Plymouth and especially along the area between Rame Head and the region of the Eddystone. The 35 mm films were viewed under a binocular microscope and the taxa that could be recognised recorded in note form. Twenty-five images were selected for inclusion in the report. Almost all of the images were of level sediment seabed. Where rocks were included, it was usually unplanned and the sled was hauled before being caught or damaged. The main biotopes or biotope complexes identified were: SS.SMU.CSaMu. Circalittoral sandy mud. Extensively present between the shore and the Eddystone Reef complex and at depths of about 48 to 52 m. At one site offshore of Plymouth Sound, the turret shell Turritella communis was abundant. In some areas, this biotope had dense anemones, Mesacmaea mitchelli and (more rarely) Cerianthus lloydii. Queen scallops, Aequipecten opercularis and king scallops, Pecten maximus, were sometimes present in small numbers. Hard substratum species such as hydroids, dead mens fingers Alcyonium digitatum and the cup coral Caryophyllia smithii occurred in a few places, probably attached to shells or stones beneath the surface. South of the spoil ground off Hilsea Point at 57m depth, the sediment was muddier but is still assigned to this biotope complex. It is notable that three small sea pens, most likely Virgularia mirabilis, were seen here. SS.SMx.CMx. Circalittoral mixed sediment. Further offshore but at about the same depth as SS.SMU.CSaMu occurred, coarse gravel with some silt was present. The sediment was characterised must conspicuously by small queen scallops, Aequipecten opercularis. Peculiarly, there were ‘bundles’ of the branching bryozoan Cellaria sp. – a species normally found attached to rock. It could not be seen whether these bundles of Cellaria had been brought-together by terebellid worms but it is notable that Cellaria is recorded in historical surveys. As with many other sediments, there were occasional brittle stars, Ophiocomina nigra and Ophiura ophiura. Where sediments were muddy, the burrowing anemone Mesacmaea mitchelli was common. Where pebbles or cobbles occurred, there were attached species such as Alcyonium digitatum, Caryophyllia smithii and the fleshy bryozoan Alcyonidium diaphanum. Undescribed biotope. Although most likely a part of SS.SMx.CMx, the biotope visually dominated by a terebellid worm believed to be Thelepus cincinnatua, is worth special attention as it may be an undescribed biotope. The biotope occurred about 22 nautical miles south of the latitude of the Eddystone and in depths in excess of 70 m. SS.SCS.CCS.Blan. Branchiostoma lanceolatum in circalittoral coarse sand with shell gravel at about 48m depth and less. This habitat was the ‘classic’ ‘Eddystone Shell Gravel’ which is sampled for Branchiostoma lanceolatum. However, no Branchiostoma lanceolatum could be seen. The gravel was almost entirely bare of epibiota. There were occasional rock outcrops or cobbles which had epibiota including encrusting calcareous algae, the sea fan Eunicella verrucosa, cup corals, Caryophyllia smithii, hydroids and a sea urchin Echinus esculentus. The variety of species visible on the surface is small and therefore identification to biotope not usually possible. Historical records from sampling surveys that used grabs and dredges at the end of the 19th century and early 20th century suggest similar species present then. Illustrations of some of the infaunal communities from work in the 1920’s is included in this report to provide a context to the epifaunal photographs.

Influence of drugs, demographics and medical history on hospital readmission of elderly patients - A predictive model

Objective: To investigate factors that influence hospital readmissions of elderly patients and to construct a robust hospital readmissions predictive model.

Establishing a minimum dataset for prospective registration of systematic reviews: an international consultation

Background: In response to growing recognition of the value of prospective registration of systematic review protocols, we planned to develop a web-based open access international register. In order for the register to fulfil its aims of reducing unplanned duplication, reducing publication bias, and providing greater transparency, it was important to ensure the appropriate data were collected. We therefore undertook a consultation process with experts in the field to identify a minimum dataset for registration. Methods and Findings: A two-round electronic modified Delphi survey design was used. The international panel surveyed included experts from areas relevant to systematic review including commissioners, clinical and academic researchers, methodologists, statisticians, information specialists, journal editors and users of systematic reviews. Direct invitations to participate were sent out to 315 people in the first round and 322 in the second round. Responses to an open invitation to participate were collected separately. There were 194 (143 invited and 51 open) respondents with a 100% completion rate in the first round and 209 (169 invited and 40 open) respondents with a 91% completion rate in the second round. In the second round, 113 (54%) of the participants reported having previously taken part in the first round. Participants were asked to indicate whether a series of potential items should be designated as optional or required registration items, or should not be included in the register. After the second round, a 70% or greater agreement was reached on the designation of 30 of 36 items. Conclusions: The results of the Delphi exercise have established a dataset of 22 required items for the prospective registration of systematic reviews, and 18 optional items. The dataset captures the key attributes of review design as well as the administrative details necessary for registration.

Evaluation of a DVD for women with diabetes: impact on knowledge and attitudes to preconception care

Aims: To determine if an educational DVD increases knowledge and changes attitudes of women with diabetes towards preconception care.

Methods: Ninety-seven women with diabetes (Type 1, n = 89; Type 2, n = 8), aged 18–40 years, completed a pre-DVD and post-DVD intervention study by postal questionnaire. Beliefs and attitudes associated with preventing an unplanned pregnancy and seeking preconception care were assessed using a validated questionnaire; scales included benefits, barriers, personal attitudes and self-efficacy. Knowledge of pregnancy planning and pregnancy-related risks were assessed by a 22-item questionnaire.

Results: After viewing the DVD there was significant positive change in women’s perceived benefits of, and their personal attitudes to, receiving preconception care and using contraception: change in score post-DVD viewing 0.7 (95% confidence interval 0.3, 1.2), P = 0.003, and 0.8 (0.3, 1.2), P = 0.001, respectively. The DVD significantly improved self-efficacy, that is, self-confidence to use contraception for prevention of an unplanned pregnancy and to access preconception care [3.3 (1.9, 4.7), P < 0.001], and significantly reduced perceived barriers to preconception care [-0.7 (-1.2, -0.2), P = 0.01]. Knowledge of pregnancy planning and pregnancy-related risks increased significantly after viewing the DVD: mean increase was 37.6 ± 20.0%, P < 0.001, and 16.9 ± 21.2%, P < 0.001, respectively.

Conclusions: This study demonstrates the effectiveness of a DVD in increasing knowledge and enhancing attitudes of women with diabetes to preconception care. This DVD could be used as a prepregnancy counselling resource to prepare women with diabetes for pregnancy.

Joined-up government in Ireland:From un-strategic choices to patriotic imperatives

Over the last decade, joined-up government has assumed a prominent place in the study and practice of public management. In this article, drawing on the Irish case we adopt an institutionalist approach to the issue of joining-up government and bureaucratic reform. We explore how the period of sustained and rapid economic growth in Ireland during the 1990s was also characterised by a fragmentation of the public service and proliferation of agencies. Subsequently, as a consequence of the sharp contraction in public spending brought about by the global financial crisis, we find an accelerated process of public sector recentralisation, retrenchment and de-agencification. Much of this is occurring in an unplanned manner but under the generic banner of 'joining up' government. We identify the drivers behind these dynamics and how they have manifested themselves, as well as the changes to politicaladministrative relationships brought about by new initiatives, the power imbalances they expose, and ultimately their consequences on public service delivery. © Taylor & Francis Group, LLC.

The systematic development of an innovative DVD to raise awareness of preconception care

The purpose of this article is to describe the design, development and process evaluation of a preconception counselling resource (a DVD) for women with pre-gestational diabetes. DVD design and development centred on two key stakeholders ('DVD user group' and 'professional advisory group') working alongside a professional multimedia company. The DVD user group provided feedback on preferred DVD style, and informed modifications and improvements. The professional advisory group prepared the script, and ensured content and face validity. Evaluation of the DVD's acceptability and usefulness was assessed among women with diabetes via a postal questionnaire. Development phase: the resulting DVD is a 45-minute programme with three parts, featuring eight women with diabetes sharing their views and experiences, alongside an evidence-based commentary. The programme focuses on the importance of preventing an unplanned pregnancy (highlighting contraception) and on essential planning advice. Evaluation phase: 97 women (89 with type 1 and 8 with type 2 diabetes) evaluated the DVD using a rating scale of 0-10. Mean (SD) scores were: 9.1 (1.3) for quality; 9.0 (1.4) for content; 8.8 (1.5) for interest; 8.7 (1.8) for usefulness; 7.8 (2.2) for knowledge acquisition; and 8.0 (2.1) for knowledge confirmation. This combined user and multi-professional advisory group approach has produced an innovative and highly acceptable preconception counselling resource for women with diabetes. The development process and outcome evaluation are an important point of reference for future educational programmes. Future research will evaluate the impact of this preconception counselling resource on pregnancy planning indicators and pregnancy outcome.

Skin-reducing mastectomy and one-stage implant reconstruction with a myodermal flap: A safe and effective technique in risk-reducing and therapeutic mastectomy

Introduction: Immediate reconstruction following mastectomy for breast cancer has been shown to be oncologically safe and associated with improved psychosocial outcomes for patients. Bostwick described a technique for one-stage implant based reconstruction, combining skin-sparing mastectomy with concurrent reduction of the skin envelope. This report reviews the experience of a single centre using skin-reducing mastectomy and one-stage implant reconstruction in both early stage breast cancer and risk-reducing mastectomy, with specific reference to frequency of complications, implant loss and oncological outcomes.

Methods and results: A retrospective review was undertaken to identify women who had undergone skin-reducing mastectomy and one-stage implant reconstruction using a de-epithelialised dermal flap, between October 2008 and October 2012. One hundred and four consecutive mastectomies, with reconstruction, were performed by two surgeons on 64 patients. No complications were seen in 43.8% of patients. At three months, four implants were lost (3.8% of breast reconstructions, 6.3% of patients), due to either peri-implant infection or mastectomy skin flap necrosis. One patient required unplanned return to theatre for evacuation of a haematoma. Minor mastectomy skin flap necrosis was seen in 10 breasts (9.6% of reconstructed breasts) and superficial wound infection in 8 breasts (7.7% of reconstructed breasts). All of these complications were managed conservatively and none required operative intervention. At a median follow up of 35 months (4-53 months) there had been one episode of ipsilateral axillary nodal recurrence.

Conclusion: One-stage implant reconstruction using a myo-dermal flap technique following skin-reducing mastectomy is safe and should be considered in selected patients. Most complications are minor and will resolve with conservative management. Major complications such as implant failure or immediate reoperation, were relatively uncommon (6.3% patients, 3.8% of reconstructed breasts). Early follow-up suggests that oncological outcomes are satisfactory, but longer follow-up is required to substantiate this.

Design and Development of a Film-based Intervention about Teenage Men and Unintended Pregnancy: Applying the Medical Research Council Framework in Practice

Following the UK Medical Research Council’s (MRC) guidelines for the development and evaluation of complex interventions, this study aimed to design, develop and optimise an educational intervention about young men and unintended teenage pregnancy based around an interactive film. The process involved identification of the relevant evidence base, development of a theoretical understanding of the phenomenon of unintended teenage pregnancy in relation to young men, and exploratory mixed methods research. The result was an evidence-based, theory-informed, user-endorsed intervention designed to meet the much neglected pregnancy education needs of teenage men and intended to increase both boys’ and girls’ intentions to avoid an unplanned pregnancy during adolescence. In prioritising the development phase, this paper addresses a gap in the literature on the processes of research-informed intervention design. It illustrates the application of the MRC guidelines in practice while offering a critique and additional guidance to programme developers on the MRC prescribed processes of developing interventions. Key lessons learned were: 1) know and engage the target population and engage gatekeepers in addressing contextual complexities; 2) know the targeted behaviours and model a process of change; and 3) look beyond development to evaluation and implementation.

Using Digital Photography and Video in Participant Observation of Contentious Events

In this article, we discuss our experiences of using photography and video while observing contentious parades and protests in Belfast. We show how our use of these methods drew us into a series of unplanned for non-verbal interactions with other event participants who were also freely and abundantly using photographic and filming equipment to capture their own images. This interactive use of photography and video affected us emotionally and influenced what we noticed and what we omitted in our observations. In particular, it forced us to reflect upon and question our role as researchers in the events we observed and in the changing balance of power between researchers and researched.

A Conditional Approach for Modelling Patient Re-admissions in Hospital using a mixture of Coxian phase-type distributions incorporating Bayes Theorem

The number of elderly patients requiring hospitalisation in Europe is rising. With a greater proportion of elderly people in the population comes a greater demand for health services and, in particular, hospital care. Thus, with a growing number of elderly patients requiring hospitalisation competing with non-elderly patients for a fixed (and in some cases, decreasing) number of hospital beds, this results in much longer waiting times for patients, often with a less satisfactory hospital experience. However, if a better understanding of the recurring nature of elderly patient movements between the community and hospital can be developed, then it may be possible for alternative provisions of care in the community to be put in place and thus prevent readmission to hospital. The research in this paper aims to model the multiple patient transitions between hospital and community by utilising a mixture of conditional Coxian phase-type distributions that incorporates Bayes' theorem. For the purpose of demonstration, the results of a simulation study are presented and the model is applied to hospital readmission data from the Lombardy region of Italy.

A Community Driven Approach to Reconstruction Management

Without human beings, and human activities, hazards can strike but disasters cannot occur, they are not just natural phenomena but a social event (Van Der Zon, 2005). The rapid demand for reconstruction after disastrous events can result in the impacts of projects not being carefully considered from the outset and the opportunity to improve long-term physical and social community structures being neglected. The events that struck Banda Aceh in 2004 have been described as
a story of ‘two tsunamis’, the first being the natural hazard that struck and the second being the destruction of social structures that occurred as a result of unplanned, unregulated and uncoordinated response (Syukrizal et al, 2009). Measures must be in place to ensure that, while aiming to meet reconstruction
needs as rapidly as possible, the risk of re-occurring disaster impacts are reduced through both the physical structures and the capacity of the community who inhabit them. The paper explores issues facing reconstruction in a post-disaster scenario, drawing on the connections between physical and social reconstruction in order to address long term recovery solutions. It draws on a study of relevant literature and a six week pilot study spent in Haiti exploring the progress of recovery in the Haitian capital and the limitations still restricting reconstruction efforts. The study highlights the need for recovery management strategies that recognise the link between social and physical reconstruction and the significance of community based initiatives that see local residents driving recovery in terms of debris handling and rebuilding. It demonstrates how a community driven approach to physical reconstruction could also address the social impacts of events that, in the case of places such as Haiti, are still dramatically restricting recovery efforts.

Age-period-cohort effects in the incidence of hip fractures: political and economic events are coincident with changes in risk

Introduction: Healthcare improvements have allowed prevention but have also increased life expectancy, resulting in more people being at risk. Our aim was to analyse the separate effects of age, period and cohort on incidence rates by sex in Portugal, 2000–2008. Methods: From the National Hospital Discharge Register, we selected admissions (aged ≥49 years) with hip fractures (ICD9-CM, codes 820.x) caused by low/moderate trauma (falls from standing height or less), readmissions and bone cancer cases. We calculated person-years at risk using population data from Statistics Portugal. To identify period and cohort effects for all ages, we used an age–period–cohort model (1-year intervals) followed by generalised additive models with a negative binomial distribution of the observed incidence rates of hip fractures. Results: There were 77,083 hospital admissions (77.4 % women). Incidence rates increased exponentially with age for both sexes (age effect). Incidence rates fell after 2004 for women and were random for men (period effect). There was a general cohort effect similar in both sexes; risk of hip fracture altered from an increasing trend for those born before 1930 to a decreasing trend following that year. Risk alterations (not statistically significant) coincident with major political and economic change in the history of Portugal were observed around birth cohorts 1920 (stable–increasing), 1940 (decreasing–increasing) and 1950 (increasing–decreasing only among women). Conclusions: Hip fracture risk was higher for those born during major economically/politically unstable periods. Although bone quality reflects lifetime exposure, conditions at birth may determine future risk for hip fractures.

Time to Left Ventricular Reverse Remodeling after Cardiac Resynchronization Therapy: Better Late than Never

INTRODUCTION: Left ventricular reverse remodeling (LVRR), defined as reduction of end-diastolic and end-systolic dimensions and improvement of ejection fraction, is associated with the prognostic implications of cardiac resynchronization therapy (CRT). The time course of LVRR remains poorly characterized. Nevertheless, it has been suggested that it occurs ≤6 months after CRT. OBJECTIVE: To characterize the long-term echocardiographic and clinical evolution of patients with LVRR occurring >6 months after CRT and to identify predictors of a delayed LVRR response. METHODS: A total of 127 consecutive patients after successful CRT implantation were divided into three groups according to LVRR response: Group A, 19 patients (15%) with LVRR after >6 months (late LVRR); Group B, 58 patients (46%) with LVRR before 6 months (early LVRR); and Group C, 50 patients (39%) without LVRR during follow-up (no LVRR). RESULTS: The late LVRR group was older, more often had ischemic etiology and fewer patients were in NYHA class ≤II. Overall, group A presented LVRR between group B and C. This was also the case with the percentage of clinical response (68.4% vs. 94.8% vs. 38.3%, respectively, p<0.001), and hospital readmissions due to decompensated heart failure (31.6% vs. 12.1% vs. 57.1%, respectively, p<0.001). Ischemic etiology (OR 0.044; p=0.013) and NYHA functional class

O impacto do perfil do utente da USF durante o seu internamento

RESUMO - Introdução: Através da elaboração do presente projeto de investigação pretendeu-se analisar o que poderá influenciar o custo total de um utente internado, inscrito numa USF, que foi seguidamente internado no setor hospitalar. Recorreu-se à base de dados de uma USF e de um hospital, ambos pertencentes à ARS Alentejo do ano de 2010. O objetivo central consiste em estudar a relação do volume de consultas da USF e se o tipo de admissão no hospital, sendo ela programada ou não programada, explica a variância o custo do internamento. Metodologia: Foi efetuado o cruzamento entre os dados dos utentes inscritos na USF e o total de internamento hospitalar, utilizando a sua data de nascimento e respetivo sexo. Após efetuado o cruzamento, através de um procedimento estatístico com base em SPSS, foram estipuladas pressupostos de forma a encontrar uma associação entre o custo do utente internado com as variáveis da base de dados da USF. De seguida, foi verificado se o tipo de admissão do internamento pode ou não influenciar o custo do internamento. Para efetuar tais correlações, optei por separar a amostra consoante alguns dos seus grupos mais frequentes, em que foi desagregado os internamentos referentes ao GCD 14 – Gravidez, Parto e Puerpério e dos utentes pertencentes ao escalão etários dos idosos (mais de 64 anos). Resultados: A variável da idade do utente é a que mais poderá explicar a variância do custo do internamento, apresentando sempre valores significativos para tal relação. As restantes pouco ou nada podem explicar a variância do custo do internamento. Quanto à tipologia de admissão, o facto de ser programado poderá explicar a diminuição dos dias de internamento, que concomitantemente poderá diminuir o custo do internamento, devido a forte correlação existente entre elas (r=0,666). Conclusão: A introdução da integração dos cuidados de saúde a nível primário e secundário poderá ser a solução base para a redução dos gastos desnecessários na saúde. Um maior acompanhamento do utente nos CSP poderá reduzir a frequência hospitalar, como verificamos que as variáveis da USF e o facto de a consulta ser programada podem explicar tal variância.
