Implementation of a pan-European ecosystem and an interoperable platform for Smart and Healthy Ageing in Europe: An Innovation Action research protocol.

As life expectancy continues to increase in most EU Member States, smart technologies can help enable older people to continue living at home, despite the challenges accompanying the ageing process. The Innovation Action (IA) SHAPES 'Smart and Healthy Ageing through People Engaging in Supportive Systems' funded by the EU under the Horizon 2020 Research and Innovation Programme (grant agreement number 857159) attends to these topics to support active and healthy ageing and the wellbeing of older adults. This protocol article outlines the SHAPES project's objectives and aims, methods, structure, and expected outcomes. SHAPES seeks to build, pilot, and deploy a large-scale, EU-standardised interoperable, and scalable open platform. The platform will facilitate the integration of a broad range of technological, organisational, clinical, educational, and social solutions. SHAPES emphasises that the home is much more than a house-space; it entails a sense of belonging, a place and a purpose in the community. SHAPES creates an ecosystem - a network of relevant users and stakeholders - who will work together to scale-up smart solutions. Furthermore, SHAPES will create a marketplace seeking to connect demand and supply across the home, health and care services. Finally, SHAPES will produce a set of recommendations to support key stakeholders seeking to integrate smart technologies in their care systems to mediate care delivery. Throughout, SHAPES adopts a multidisciplinary research approach to establish an empirical basis to guide the development of the platform. This includes long-term ethnographic research and a large-scale pan-European campaign to pilot the platform and its digital solutions within the context of seven distinct pilot themes. The project will thereby address the challenges of ageing societies in Europe and facilitate the integration of community-based health and social care. SHAPES will thus be a key driver for the transformation of healthcare and social care services across Europe.

The dialectics of heroin and methadone in Ireland.

In this paper, I reflect on two of my intertwined research interests. The first is my professional engagement with researching drug use and abuse in Ireland, especially heroin addiction, in applied ethnographic projects, generally answering a specific set of questions on how services for 'drug addiction' work. My second interest is the historical construction of 'addiction' and the discursive intersections that produce various kinds of power, subjects, and techniques around this concept. I find the dialectical relationship between heroin and methadone in Ireland, especially the emergence of heroin 'injecting rooms', as a window into how drugs are social things. Drugs and the bodies who take them live in complex moral worlds, not as inert objects surrounded by abstract human creations. These worlds are an integral part of how 'addiction' works and how drugs treating addiction are actually used. Without a deeper understanding of such complexities we will continue to miss key issues in the lives of people we hope to help.

Are patients ready for integrated person-centered care? A qualitative study of people with epilepsy in Ireland.

The National Clinical Programme for Epilepsy (NCPE) in Ireland aims to deliver a holistic model of integrated person-centered care (PCC) that addresses the full spectrum of biomedical and psychosocial needs of people with epilepsy (PwE). However, like all strategic plans, the model encompasses an inherent set of assumptions about the readiness of the environment to implement and sustain the actions required to realize its goals. In this study, through the lens of PwE, the Irish epilepsy care setting was explored to understand its capacity to adopt a new paradigm of integrated PCC. Focus groups and semi-structured one-to-one interviews were employed to capture the qualitative experiences of a sample of Irish PwE (n = 27) in the context of the care that they receive. Participants were from different regions of the country and were aged between 18 and 55 years with 1 to 42 years since diagnosis (YSD). Highlighting a gap between policy intent and action on the ground, findings suggest that patient readiness to adopt a new model of care cannot be assumed. Expectations, preferences, behaviors, and values of PwE may sustain the more traditional constructions of healthcare delivery rather than the integrated PCC goals of reform. These culturally constituted perceptions illustrate that PwE do not instinctively appreciate the goals of healthcare reform nor the different behavior expected from them within a reformed healthcare system. Recalibrating deep-rooted patient views is necessary to accomplish the aspirations of integrated PCC. Patient engagement emphasizing the meaningful role that they can play in shaping their healthcare services is vital.

The rhetoric and reality of integrated patient-centered care for healthcare providers: An ethnographic exploration of epilepsy care in Ireland.

In line with healthcare reform across the world, the National Clinical Programme for Epilepsy (NCPE) in Ireland describes a model that aims to achieve holistic integrated person (patient)-centered care (PCC). While generally welcomed by stakeholders, the steps required to realize the NCPE ambition and the preparedness of those involved to make the journey are not clear. This study explored the perceptions of healthcare providers in the Irish epilepsy care ecosystem to understand their level of readiness to realize the benefits of an integrated PCC model. Ethnographic fieldwork including observations of different clinical settings across three regions in Ireland and one-to-one interviews with consultant epileptologists (n = 3), epilepsy specialist nurses (n = 5), general practitioners (n = 4), and senior healthcare managers (n = 3) were conducted. While there is a person-centered ambiance and a disposition toward advancing integrated PCC, there are limits to the readiness of the epilepsy care environment to fully meet the aspirations of healthcare reform. These are the following: underdeveloped healthcare partnerships;, poor care coordination;, unintended consequences of innovation;, and tension between pace and productivity. In the journey from policy to practice, the following multiple tensions collide: policy aims to improve services for all patients while simultaneously individualizing care; demands for productivity limit the time and space required to engage in incremental and iterative improvement initiatives. Understanding these tensions is an essential first step on the pathway to integrated PCC implementation.

Effect of aspirin intake at bedtime versus on awakening on circadian rhythm of platelet reactivity. A randomised cross-over trial.

The risk of acute cardiovascular events is highest during morning hours, and platelet activity peaks during morning hours. The effect of timing of aspirin intake on circadian rhythm and morning peak of platelet reactivity is not known. It was our objective to evaluate the effect of timing of aspirin intake on circadian rhythm and morning peak of platelet reactivity. A randomised open-label cross-over trial in healthy subjects (n=14) was conducted. Participants used acetylsalicylic acid (80 mg) on awakening or at bedtime for two periods of two weeks, separated by a four-week wash-out period. At the end of both periods blood was drawn every 3 hours to measure COX-1-dependent (VerifyNow-Aspirin; Serum Thromboxane B2 [STxB2]) and COX-1-independent (flow cytometry surface CD62p expression; microaggregation) platelet activity. VerifyNow platelet reactivity over the whole day was similar with intake on awakening and at bedtime (mean difference: -9 [95 % confidence interval (CI) -21 to 4]). However, the morning increase in COX-1-dependent platelet activity was reduced by intake of aspirin at bedtime compared with on awakening (mean difference VerifyNow: -23 Aspirin Reaction Units [CI -50 to 4]; STxB2: -1.7 ng/ml [CI -2.7 to -0.8]). COX-1-independent assays were not affected by aspirin intake or its timing. Low-dose aspirin taken at bedtime compared with intake on awakening reduces COX-1-dependent platelet reactivity during morning hours in healthy subjects. Future clinical trials are required to investigate whether simply switching to aspirin intake at bedtime reduces the risk of cardiovascular events during the high risk morning hours.

Ultrafast vascular strain compounding using plane wave transmission.

Deformations of the atherosclerotic vascular wall induced by the pulsating blood can be estimated using ultrasound strain imaging. Because these deformations indirectly provide information on mechanical plaque composition, strain imaging is a promising technique for differentiating between stable and vulnerable atherosclerotic plaques. This paper first explains 1-D radial strain estimation as applied intravascularly in coronary arteries. Next, recent methods for noninvasive vascular strain estimation in a transverse imaging plane are discussed. Finally, a compounding technique that our group recently developed is explained. This technique combines motion estimates of subsequently acquired focused ultrasound images obtained at various insonification angles. However, because the artery moves and deforms during the multi-angle acquisition, errors are introduced when compounding. Recent advances in computational power have enabled plane wave ultrasound acquisition, which allows 100 times faster image acquisition and thus might resolve the motion artifacts. In this paper the performance of strain imaging using plane wave compounding is investigated using simulations of an artery with a vulnerable plaque and experimental data of a two-layered vessel phantom. The results show that plane wave compounding outperforms 0° focused strain imaging. For the simulations, the root mean squared error reduced by 66% and 50% for radial and circumferential strain, respectively. For the experiments, the elastographic signal-to-noise and contrast-to-noise ratio (SNR(e) and CNR(e)) increased with 2.1 dB and 3.7 dB radially, and 5.6 dB and 16.2dB circumferentially. Because of the high frame rate, the plane wave compounding technique can even be further optimized and extended to 3D in future.

Energy requirements are altered in critically-ill patients and are influenced by the clinical situation, treatment, and phase of the process. Therefore, the most appropriate method to calculate calorie intake is indirect calorimetry. In the absence of this technique, fixed calorie intake (between 25 and 35 kcal/kg/day) or predictive equations such as the Penn State formula can be used to obtain a more accurate evaluation of metabolic rate. Carbohydrate administration should be limited to a maximum of 4 g/kg/day and a minimum of 2 g/kg/day. Plasma glycemia should be controlled to avoid hyperglycemia. Fat intake should be between 1 and 1.5g/kg/day. The recommended protein intake is 1-1.5g/kg/day but can vary according to the patient’s clinical status. Particular attention should be paid to micronutrient intake. Consensus is lacking on micronutrient requirements. Some vitamins (A, B, C, E) are highly important in critically-ill patients, especially those undergoing continuous renal replacement techniques, patients with severe burns and alcoholics, although the specific requirements in each of these types of patient have not yet been established. Energy and protein intake in critically-ill patients is complex, since both clinical factors and the stage of the process must be taken into account. The first step is to calculate each patient’s energy requirements and then proceed to distribute calorie intake among its three components: proteins, carbohydrates and fat. Micronutrient requirements must also be considered (AU)

An uncertain dominion: Irish psychiatry, methadone, and the treatment of opiate abuse.

This paper investigates some productive ambiguities around the medical administration of methadone in the Republic of Ireland. The tensions surrounding methadone maintenance therapy (MMT) are outlined, as well as the sociohistorical context in which a serious heroin addiction problem in Ireland developed. Irish psychiatry intervened in this situation, during a time of institutional change, debates concerning the nature of addiction, moral panics concerning heroin addiction in Irish society and the recent boom in the Irish economy, known popularly as the Celtic Tiger. A particular history of this sort illuminates how technologies like MMT become cosmopolitan, settling into, while changing, local contexts.

[Recommendations for nutritional assessment and specialized nutritional support of critically ill patients]. / Recomendaciones para la valoración nutricional y el soporte nutricional especializado de los pacientes críticos.

Due to the characteristics of critically ill patients, elaborating recommendations on nutritional support for these patients is difficult. Usually the time of onset of nutritional support or its features are not well established, so that its application is based on experts' opinion. In the present document, recommendations formulated by the Metabolism and Nutrition Working Group of the Spanish Society of Intensive and Critical Medicine and Coronary Units (SEMICYUC) are presented. Recommendations are based on the literature analysis and further discussion by the working group members in order to define, consensually, the more relevant issues of metabolic and nutritional support of patients in a critical condition. Several clinical situations have been considered which are developed in the following articles of this publication. The present recommendations aim at providing a guideline for the less experienced clinicians when considering the metabolic and nutritional issues of critically ill patients.
