Assessing the health outcomes of the family members of disabled individuals

The health utilization and death rates were captured for the family members of disabled individuals over a fifteen-year period to determine if exposure to disability in the family manifests poor health outcomes. Data from the Newfoundland Adult Health Survey (1995) was linked to fifteen years, 1995- 2010, of provincial health administrative data including hospital data, physician claims, and death records from the provincial health care system. The health records and survey data were analyzed in relation to the disability exposure burden experienced when a family member is disabled. The level of disability exposure burden was quantified based on the addition of individual disability scores for each family member. Disability exposure burden was associated with increased number of hospital separations, total hospitalization days and the number of physician visits, both General Practitioner and Specialist (p<0.1) but there was no association between death (p>0.1) and disability exposure burden. Family members of disabled individuals experienced increased rates of hospital separations, hospitalization days, and physician visits suggesting that deleterious health outcomes may be introduced when individuals are exposed to disability in the family unit.

The Relationship Between Support Systems and Disease Burden for Families Coping with Sickle Cell Disease in South Africa and Cameroon

Background: Sickle cell disease (SCD) is a debilitating genetic blood disorder that seriously impacts the quality of life of affected individuals and their families. With 85% of cases occurring in sub-Saharan Africa, it is essential to identify the barriers and facilitators of optimal outcomes for people with SCD in this setting. This study focuses on understanding the relationship between support systems and disease outcomes for SCD patients and their families in Cameroon and South Africa.

Methods: This mixed-methods study utilizes surveys and semi-structured interviews to assess the experiences of 29 SCD patients and 28 caregivers of people with SCD across three cities in two African countries: Cape Town, South Africa; Yaoundé, Cameroon; and Limbe, Cameroon.

Results: Patients in Cameroon had less treatment options, a higher frequency of pain crises, and a higher incidence of malaria than patients in South Africa. Social support networks in Cameroon consisted of both family and friends and provided emotional, financial, and physical assistance during pain crises and hospital admissions. In South Africa, patients relied on a strong medical support system and social support primarily from close family members; they were also diagnosed later in life than those in Cameroon.

Conclusions: The strength of medical support systems influences the reliance of SCD patients and their caregivers on social support systems. In Cameroon the health care system does not adequately address all factors of SCD treatment and social networks of family and friends are used to complement the care received. In South Africa, strong medical and social support systems positively affect SCD disease burden for patients and their caregivers. SCD awareness campaigns are necessary to reduce the incidence of SCD and create stronger social support networks through increased community understanding and decreased stigma.

Parental Bereavement: Looking Beyond Grief - Challenges and Health

For most parents there is no imaginable event more devastating than the death of their child. Nevertheless, while bereaved parents grieve they are also expected to carry on with their life. The day-to-day activities that were once routine for these parents may now be challenging due to the emotional turmoil they are experiencing. To date parental bereavement has been described as complex, intense, individualized, and life-long and their grief responses are interwoven with their daily activities, but the nature of their daily life challenges are not known.

This dissertation highlights the significance of how parents respond to their bereavement challenges because bereaved parents have higher morbidity and mortality rates than non-bereaved parents or adults who have lost their spouse or parents. Many bereaved parents in their daily routines include activities that allow them to maintain a relationship with their deceased child. These behaviors have been described as “continuing bonds”, but with this dissertation the continuing bonds concept is analyzed to provide a clear conceptual definition, which can be used for future research.

Using the Adaptive Leadership Framework as the theoretical lens and a mixed method, multiple case study design, the primary study in this dissertation aims to provides knowledge about the challenges parents face in the first six months following the death of their child, the work they use to meet these challenges, and the co-occurrence of the challenges, and work with their health status. Bereaved parents challenges are unique to their individual circumstances, complex, interrelated and adaptive, as they have no easy fix. Their challenges were pertaining to their everyday life without their child and classified as challenges related to: a) grief, b) continuing bonds, c) life demands, d) health concerns, f) interactions, and g) gaps in the health care system. Parents intuitively responded to the challenges and attempted to care for themselves. However, the role of the healthcare system to assist bereaved parents during this stressful time so that their health is not negatively impacted was also recognized. This study provides a foundation about parental bereavement challenges and related work that can lead to the development and testing of interventions that are tailored to address the challenges with a goal of improving bereaved parents health outcomes.

Identification des grands utilisateurs de soins de santé chez les patients souffrant de la douleur chronique non cancéreuse et suivis en soins de première ligne

Contexte: La douleur chronique non cancéreuse (DCNC) génère des retombées économiques et sociétales importantes. L’identification des patients à risque élevé d’être de grands utilisateurs de soins de santé pourrait être d’une grande utilité; en améliorant leur prise en charge, il serait éventuellement possible de réduire leurs coûts de soins de santé. Objectif: Identifier les facteurs prédictifs bio-psycho-sociaux des grands utilisateurs de soins de santé chez les patients souffrant de DCNC et suivis en soins de première ligne. Méthodologie: Des patients souffrant d’une DCNC modérée à sévère depuis au moins six mois et bénéficiant une ordonnance valide d’un analgésique par un médecin de famille ont été recrutés dans des pharmacies communautaires du territoire du Réseau universitaire intégré de santé (RUIS), de l’Université de Montréal entre Mai 2009 et Janvier 2010. Ce dernier est composé des six régions suivantes : Mauricie et centre du Québec, Laval, Montréal, Laurentides, Lanaudière et Montérégie. Les caractéristiques bio-psycho-sociales des participants ont été documentées à l’aide d’un questionnaire écrit et d’une entrevue téléphonique au moment du recrutement. Les coûts directs de santé ont été estimés à partir des soins et des services de santé reçus au cours de l’année précédant et suivant le recrutement et identifiés à partir de la base de données de la Régie d’Assurance maladie du Québec, RAMQ (assureur publique de la province du Québec). Ces coûts incluaient ceux des hospitalisations reliées à la douleur, des visites à l’urgence, des soins ambulatoires et de la médication prescrite pour le traitement de la douleur et la gestion des effets secondaires des analgésiques. Les grands utilisateurs des soins de santé ont été définis comme étant ceux faisant partie du quartile le plus élevé de coûts directs annuels en soins de santé dans l’année suivant le recrutement. Des modèles de régression logistique multivariés et le critère d’information d’Akaike ont permis d’identifier les facteurs prédictifs des coûts directs élevés en soins de santé. Résultats: Le coût direct annuel médian en soins de santé chez les grands utilisateurs de soins de santé (63 patients) était de 7 627 CAD et de 1 554 CAD pour les utilisateurs réguliers (188 patients). Le modèle prédictif final du risque d’être un grand utilisateur de soins de santé incluait la douleur localisée au niveau des membres inférieurs (OR = 3,03; 95% CI: 1,20 - 7,65), la réduction de la capacité fonctionnelle liée à la douleur (OR = 1,24; 95% CI: 1,03 - 1,48) et les coûts directs en soins de santé dans l’année précédente (OR = 17,67; 95% CI: 7,90 - 39,48). Les variables «sexe», «comorbidité», «dépression» et «attitude envers la guérison médicale» étaient également retenues dans le modèle prédictif final. Conclusion: Les patients souffrant d’une DCNC au niveau des membres inférieurs et présentant une détérioration de la capacité fonctionnelle liée à la douleur comptent parmi ceux les plus susceptibles d’être de grands utilisateurs de soins et de services. Le coût direct en soins de santé dans l’année précédente était également un facteur prédictif important. Améliorer la prise en charge chez cette catégorie de patients pourrait influencer favorablement leur état de santé et par conséquent les coûts assumés par le système de santé.

Santeria as an Informal Psychosocial Support Among Latinas Living with Cancer

Among Latinos, Santería functions as both a religion and a health care system in occurrences of health versus illness within various Latino sub-groups in the U.S. This exploratory study offers a comprehensive analysis of the function of the folk healing tradition Santería as a culturally congruent informal mental health support that assists with coping with the psychosocial sequelae of living with cancer among Latinas in Miami-Dade County, FL. It (a) determined the attitudes of Latinas living with cancer towards Santería as an informal mental health support and (b) explored how Santería offers Latinas effective mental health support that assists in coping with the psychosocial sequelae of living with cancer. The mechanisms and characteristics underlying the motivations of Latinas living with cancer to seek and integrate this informal modality for their cancer care were identified. A purposive sample of 15 Latinas ages 18 and older in Miami-Dade County who had received a diagnosis of cancer were recruited from sites in Miami-Dade offering formal mental health support services and botánicas. Data collection incorporated in-depth interviews and a validation focus group. In an effort to generate theory through a modified Grounded Theory approach, data analysis was accomplished by means of multiple coding passes and the constant comparison method which resulted in higher levels codes that were grouped into three major themes: 1) Participants’ Experience with Folk Healers, 2) Influence of Santería on the Cancer Experience, and 3) Participants’ Experience with Conventional Healthcare and Mental Healthcare. Results illustrate how, among Latinas, the folk healing tradition of Santería co-occurs with professional medical and mental health treatment in what Arthur Kleinman defines as the popular sector, which identifies and sets the parameters for culturally acceptable forms of healthcare and mental health treatment options.

Optimization of Cooling Protocols for Hearts Destined for Transplantation

Design and analysis of conceptually different cooling systems for the human heart preservation are numerically investigated. A heart cooling container with required connections was designed for a normal size human heart. A three-dimensional, high resolution human heart geometric model obtained from CT-angio data was used for simulations. Nine different cooling designs are introduced in this research. The first cooling design (Case 1) used a cooling gelatin only outside of the heart. In the second cooling design (Case 2), the internal parts of the heart were cooled via pumping a cooling liquid inside both the heart’s pulmonary and systemic circulation systems. An unsteady conjugate heat transfer analysis is performed to simulate the temperature field variations within the heart during the cooling process. Case 3 simulated the currently used cooling method in which the coolant is stagnant. Case 4 was a combination of Case 1 and Case 2. A linear thermoelasticity analysis was performed to assess the stresses applied on the heart during the cooling process. In Cases 5 through 9, the coolant solution was used for both internal and external cooling. For external circulation in Case 5 and Case 6, two inlets and two outlets were designed on the walls of the cooling container. Case 5 used laminar flows for coolant circulations inside and outside of the heart. Effects of turbulent flow on cooling of the heart were studied in Case 6. In Case 7, an additional inlet was designed on the cooling container wall to create a jet impinging the hot region of the heart’s wall. Unsteady periodic inlet velocities were applied in Case 8 and Case 9. The average temperature of the heart in Case 5 was +5.0oC after 1500 s of cooling. Multi-objective constrained optimization was performed for Case 5. Inlet velocities for two internal and one external coolant circulations were the three design variables for optimization. Minimizing the average temperature of the heart, wall shear stress and total volumetric flow rates were the three objectives. The only constraint was to keep von Mises stress below the ultimate tensile stress of the heart’s tissue.

Market reforms and privatisation in the English National Health Service

The article examines developments in the marketisation and privatisation of the English National Health Service, primarily since 1997. It explores the use of competition and contracting out in ancillary services and the levering into public services of private finance for capital developments through the Private Finance Initiative. A substantial part of the article examines the repeated restructuring of the health service as a market in clinical services, initially as an internal market but subsequently as a market increasing opened up to private sector involvement. Some of the implications of market processes for NHS staff and for increased privatisation are discussed. The article examines one episode of popular resistance to these developments, namely the movement of opposition to the 2011 health and social care legislative proposals. The article concludes with a discussion of the implications of these system reforms for the founding principles of the NHS and the sustainability of the service.

Personal and Public Involvement Consultation Scheme (PDF 149KB)

The current structure of the health and social care system in Northern Ireland has its origins in the Review of Public Administration (RPA) which was initiated by the Northern Ireland Executive in June 2002. The purpose of RPA was to review Northern Ireland’s system of public administration with a view to putting in place a modern, citizen-centred, accountable and high quality system of public administration. The structure was designed to be more streamlined and accountable and aimed at maximising resources for front-line services and ensuring that people have access to high quality health and social care. Another key feature is the placement of public health and wellbeing firmly at the centre of the system, with a greater emphasis on prevention and support for vulnerable people to live independently in the community for as long as possible.  

Assessing microvascular function with breathing maneuvers : an oxygenation-sensitive CMR study

Ce projet illustre cinq études, mettant l'emphase sur le développement d'une nouvelle approche diagnostique cardiovasculaire afin d'évaluer le niveau d’oxygène contenu dans le myocarde ainsi que sa fonction microvasculaire. En combinant une séquence de résonance magnétique cardiovasculaire (RMC) pouvant détecter le niveau d’oxygène (OS), des manœuvres respiratoires ainsi que des analyses de gaz artériels peuvent être utilisés comme procédure non invasive destinée à induire une réponse vasoactive afin d’évaluer la réserve d'oxygénation, une mesure clé de la fonction vasculaire. Le nombre de tests diagnostiques cardiaques prescrits ainsi que les interventions, sont en pleine expansion. L'imagerie et tests non invasifs sont souvent effectués avant l’utilisation de procédures invasives. L'imagerie cardiaque permet d’évaluer la présence ou absence de sténoses coronaires, un important facteur économique dans notre système de soins de santé. Les techniques d'imagerie non invasives fournissent de l’information précise afin d’identifier la présence et l’emplacement du déficit de perfusion chez les patients présentant des symptômes d'ischémie myocardique. Néanmoins, plusieurs techniques actuelles requièrent la nécessité de radiation, d’agents de contraste ou traceurs, sans oublier des protocoles de stress pharmacologiques ou physiques. L’imagerie RMC peut identifier une sténose coronaire significative sans radiation. De nouvelles tendances d’utilisation de RMC visent à développer des techniques diagnostiques qui ne requièrent aucun facteur de stress pharmacologiques ou d’agents de contraste. L'objectif principal de ce projet était de développer et tester une nouvelle technique diagnostique afin d’évaluer la fonction vasculaire coronarienne en utilisant l' OS-RMC, en combinaison avec des manœuvres respiratoires comme stimulus vasoactif. Ensuite, les objectifs, secondaires étaient d’utilisés l’OS-RMC pour évaluer l'oxygénation du myocarde et la réponse coronaire en présence de gaz artériels altérés. Suite aux manœuvres respiratoires la réponse vasculaire a été validée chez un modèle animal pour ensuite être utilisé chez deux volontaires sains et finalement dans une population de patients atteints de maladies cardiovasculaires. Chez le modèle animal, les manœuvres respiratoires ont pu induire un changement significatif, mesuré intrusivement par débit sanguin coronaire. Il a été démontré qu’en présence d'une sténose coronarienne hémodynamiquement significative, l’OS-RMC pouvait détecter un déficit en oxygène du myocarde. Chez l’homme sain, l'application de cette technique en comparaison avec l'adénosine (l’agent standard) pour induire une vasodilatation coronarienne et les manœuvres respiratoires ont pu induire une réponse plus significative en oxygénation dans un myocarde sain. Finalement, nous avons utilisé les manœuvres respiratoires parmi un groupe de patients atteint de maladies coronariennes. Leurs myocardes étant altérées par une sténose coronaire, en conséquence modifiant ainsi leur réponse en oxygénation. Par la suite nous avons évalué les effets des gaz artériels sanguins sur l'oxygénation du myocarde. Ils démontrent que la réponse coronarienne est atténuée au cours de l’hyperoxie, suite à un stimuli d’apnée. Ce phénomène provoque une réduction globale du débit sanguin coronaire et un déficit d'oxygénation dans le modèle animal ayant une sténose lorsqu’un supplément en oxygène est donné. En conclusion, ce travail a permis d'améliorer notre compréhension des nouvelles techniques diagnostiques en imagerie cardiovasculaire. Par ailleurs, nous avons démontré que la combinaison de manœuvres respiratoires et l’imagerie OS-RMC peut fournir une méthode non-invasive et rentable pour évaluer la fonction vasculaire coronarienne régionale et globale.

Progettazione e prototipìa di un polso robotico ad architettura sferica

I robot industriali iniziano a diffondersi in maniera significativa verso la metà degli anni ’70, quando affrontare economicamente il costo legato alla loro progettazione e costruzione risultò più vantaggioso rispetto all’assunzione di manodopera. Nella categoria dei robot industriali rientrano anche i polsi robotici che, posti all’estremità di un braccio meccanico, possono essere impiegati in diverse applicazioni industriali. In questo ambito si inserisce il meccanismo sferico ideato da Wu e Carricato. Esso presenta un’architettura ibrida seriale-parallela e, grazie ad una disposizione simmetrica dei membri che lo costituiscono, è in grado di riprodurre il movimento del polso umano. L’attività svolta e presentata in questo elaborato è stata finalizzata alla progettazione, attraverso l’ausilio dei software Creo e Matlab, sia degli organi che compongono il dispositivo sia della trasmissione meccanica che consente l’attuazione dei 2 gradi di libertà (gdl) posseduti dal meccanismo. Sono state realizzate due versioni CAD del polso; la prima è volta alla realizzazione in materiale plastico dei componenti, sfruttando la tecnologia della stampa 3D, in modo da ottenere un primo prototipo funzionante ed operativo, in cui si sono previsti accoppiamenti rotoidali tra le parti del tipo a strisciamento. Costruito ed assemblato il prototipo in plastica, si è potuta verificare la compatibilità tra precisione costruttiva, tolleranze dimensionali e geometriche garantite dalla stampa 3D e corretto funzionamento del meccanismo. La seconda versione rappresenta una versione ingegnerizzata della precedente. In particolare, prevede la realizzazione in alluminio del polso e la progettazione dei giunti cinematici (principalmente rotoidali) utilizzando accoppiamenti volventi e non a strisciamento. In questo modo si riescono a ridurre le imperfezioni di montaggio ed i notevoli giochi introdotti dall’impiego di componenti in plastica.

El sistema español de atención a la dependencia en el contexto europeo

Europa presenta en la actualidad unas previsiones demográficas preocupantes, incrementando exponencialmente el número de las personas en situación de dependencia y su demanda de cobertura social, sanitaria y residencial. En este contexto europeo, creemos oportuno destacar el modelo de atención español, señalando sus particularidades. Para ello, en primer lugar, hemos realizado una revisión de los análisis que profundizan en las divergencias de la atención a la dependencia en los países europeos, como la forma de residencia de este sector poblacional o la capacidad de las redes sociales de cubrir sus necesidades de atención. En segundo lugar, procedemos a exponer las pretensiones del marco legislativo español, así como sus fortalezas y limitaciones. Las conclusiones apuntan a que el modelo universal implantado en España pudiera ser un referente en el contexto europeo, aunque ello dependerá de sus modelos sociales de convivencia y el contexto previo en que se desenvuelva la dependencia.

I terremoti di epoca moderna a Sansepolcro. Analisi di fonti archivistiche e indagini morfologiche sui tessuti edilizi per la comprensione del rapporto tra eventi storici e definizione degli interventi

Il presente lavoro di tesi affronta diverse tematiche riguardanti la valutazione della vulnerabilità sismica del centro storico di Sansepolcro, con particolare riferimento all’analisi di fonti storiche perlopiù inedite e a indagini morfologiche sui tessuti edilizi. La zona della Valtiberina toscana è stata interessata da numerosi eventi sismici che spesso hanno raggiunto intensità elevate e che hanno provocato molti danni. Il susseguirsi di tali eventi ha fatto si che si sviluppasse una certa esperienza nell’affrontare le conseguenze dell’evento sismico. Ne sono testimonianza i documenti conservati presso l’Archivio Storico Comunale di Sansepolcro che riguardano gli eventi sismici del 1781 e del1789. Dalla corrispondenza tra le autorità di Firenze e di Sansepolcro è stato possibile ricostruire la cronologia delle azioni principali compiute nella gestione dell’emergenza. Tra le lavorazioni eseguite, molti furono i presidi antisismici utilizzati. Nell’ambito dell’analisi delle fonti di archivio si sono analizzati anche documenti più recenti, in particolare gli elaborati del Genio Civile conservati presso l’Archivio di Stato di Arezzo riguardanti gli eventi sismici del 1917 e 1919. Parallelamente alle ricerche archivistiche si è cercato di stabilire una correlazione tra la morfologia dei tessuti e la vulnerabilità sismica degli aggregati edilizi in relazione al loro processo evolutivo e al loro periodo storico di formazione. Una volta stabilita, per ogni aggregato, la fase di impianto, ci si è avvalsi del metodo di calcolo speditivo dell’indice di vulnerabilità in pianta (TPS). Lo scopo è quello di elaborare delle considerazioni generali per singoli aggregati campione, per poi estenderle agli aggregati omogenei. A conclusione del lavoro si è preso in considerazione il caso del Palazzo Aloigi-Luzzi e se ne sono calcolati gli indici analitici globali di vulnerabilità sismica, per avere un riscontro concreto di un singolo caso.

Study of a beam-column joint of a precast system by nonlinear numerical analysis

The present work consists of a detailed numerical analysis of a 4-way joint made of a precast column and two partially precast beams. The structure has been previously built and experimentally analyzed through a series of cyclic loads at the Laboratory of Tests on Structures (Laboratorio di Prove su Strutture, La. P. S.) of the University of Bologna. The aim of this work is to design a 3D model of the joint and then apply the techniques of nonlinear finite element analysis (FEA) to computationally reproduce the behavior of the structure under cyclic loads. Once the model has been calibrated to correctly emulate the joint, it is possible to obtain new insights useful to understand and explain the physical phenomena observed in the laboratory and to describe the properties of the structure, such as the cracking patterns, the force-displacement and the moment-curvature relations, as well as the deformations and displacements of the various elements composing the joint.
