As gerontologists may know, there are a great deal of studies and a variety of academic literature on the misuse of alcohol and prescription medication amongst the elderly population. While there is a plethora of information on alcohol and prescription misuse, there is little reported data about the prevalence of other substance misuse experienced by this population. This study aims to help to fill that gap in the data by using quantitative methods to describe the scope of substance abuse of individuals 55-years or older. This study utilizes data from the Treatment Data Set Admission (TEDS-A). The TEDS-A is a public data set which includes admissions data from multiple substance abuse treatment facilities associated with the Substance Abuse and Mental Health Services Association (SAMHSA). This is a regional study, therefore this study focuses only on individuals 55-years or older who have been admitted into substance abuse treatment facilities in the state of California in the year 2014. The TEDS-A is a data set that is supported and conducted by members of SAMHSA. Most of their public data sets, including the TEDS-A, can be accessed on their website (https://www.datafiles.samhsa.gov/study/treatment-episode-data-set-admissions-teds-2014-nid16949). The data available in the TEDS-A involves a number of admission questions, including demographic data, reasons for intake, primary through tertiary substance concerns, questions regarding social status, information on medical insurance, and more. This study looks at the descriptive frequencies of the use of alcohol, crack/cocaine, marijuana/hashish, heroin, other opiates & synthetics, methamphetamine, and other substances. The study includes 13,512 cases, of which 9966 (73.8%) of cases were male, 3539 (26.2%) were female, and 7 (0.1%) were missing and/or invalid. The results of the data suggests that, while alcohol abuse is a problem, those over 55 are admitted into substance abuse clinics for many other reasons, not just alcohol abuse.

This study used narrative inquiry to answer the question “What are the stories of older adults who choose not to share information with health care professionals?” The study explored the experiences of older adults who did not share information with health care professionals (HCPs), who they defined as doctors. A thematic analysis of five participants’ stories revealed three themes: Illusions of Care, describing the participants’ experiences with doctors before they chose not to share information; The Last Straw, revealing the final incident that caused participants to choose not to share information; and The Mask of the Non-sharing Older Adult, describing how participants interacted with their doctors after they decided not to share information. Relationship development between older adults and their doctors, sensitive topics, issues and perceptions of ageing, and structure of the health care system contribute to the complex issue of older adults not sharing information. The decision not to share information with health care professionals may adversely affect the health and health care of older adults.

Úlceras por Pressão (UPP) são áreas de necrose isquêmica em partes moles, causadas por uma pressão prolongada maior que a capilar, com ou sem cisalhamento, relacionada à postura e frequentemente localizada junto a uma proeminência óssea em indivíduos com predisposição clínica. Os fatores extrínsecos pressão, fricção, cisalhamento, umidade e alterações de temperatura são relacionados à engenharia biomédica e decorrem da interação do paciente com a superfície de suporte. Já os intrínsecos, notadamente relacionados às condições de saúde, envolvem o desequilíbrio nutricional e as afecções clínicas, tanto as que diminuem a oxigenação tecidual, como as que implicam no comprometimento da mobilidade. Por ser mais prevalente entre os idosos e por decorrer de múltiplas causas e mecanismos patogênicos, as UPP são classificadas como uma Síndrome Geriátrica. Embora associada principalmente a gerontes, o aporte financeiro empregado no grupo de feridas crônicas, como as UPP, remonta o 3o maior bloco de gastos em saúde no mundo. As UPP são frequentes em pacientes hospitalizados, porém ultrapassam este ambiente, havendo expressiva incidência em residentes de Instituições de Longa Permanência para Idosos (ILPIs). No Brasil, as ILPIs são órgãos sociais, o que gera uma lacuna legal quanto à responsabilidade clínica sobre seus residentes e, consequentemente, sobre as afecções que os acometem, particularmente as UPP. Estas feridas são passíveis de prevenção, destacando-se então o cuidador de idosos, ocupação que vem aumentando em número e importância com o envelhecimento da população e que, no entanto, nem sempre é devidamente instruído. Por meio de uma vasta revisão de literatura, esta dissertação objetivou pontuar os fatores relevantes envolvidos na patogenia das UPP, além das especificidades do indivíduo idoso e do ambiente das ILPIs. Neste contexto, o produto final elaborado foi um guia para prevenção de UPP em ILPIs. / Pressure Ulcers (PU) are areas of localized soft tissue ischemic necrosis caused by prolonged pressure higher than the capillary pressure with or without shear, related to posture which usually occurs over a bony prominence in individual with certain clinical susceptibilities. Extrinsic factors – such as pressure, friction and shear, moisture and temperature changes – are related to biomedical engineering and come from the interaction patient-surface. On the other hand, intrinsic factors are related to health conditions and correspond to nutritional imbalance and/or conditions that decrease tissue oxygenation or impair mobility. Since it features different pathogenic mechanisms and it is more prevalent among the elderly, the PU group is classified as a geriatric syndrome. Worldwide, PU are estimated to be the 3rd largest consumer of resources, plus the social burden and consequences of this condition. PU are quite common in hospitals, however there are several cases among the elderly living in Long-Term Care Facilities (LTCFs). In Brazil, these institutions are supported by social organizations, what produces legal gaps with respect to the residents’ clinical responsibility, and reduces the chances of preventing avoidable diseases as PU. The number of elderly caregivers tends to grow accordingly to the population ageing, creating a window of opportunity for continued education of this group of workers. Through an extensive literature review, this thesis aimed to highlight the relevant findings of the different factors involved in PU pathogenesis as well as to ascertain the particularities of elderly individuals and the specific environment of LTCFs. The final product is a PU prevention guide suitable to use in Brazilian long-term care facilities.

<div>Older adults aged 60+ represent the fastest growing segment of the US population, yet they are rarely seen as users of technology. Members of this age cohort often struggle with the material and conceptual requirements of computing—such as clicking small targets or remembering usernames and passwords for account logins—leading them to adopt technologies like smartphones and social media at much lower rates than their younger counterparts. Digital devices and interfaces are not typically designed with older adult users in mind, even though all users are always aging, and the “silver economy” represents a powerful, and often untapped, market for technological innovations. The little existing research in this area often conflates age with disability, framing elders according to a deficit model. While it is certainly important to consider the impacts that aging bodies have on technology use, they are not the sole factor shaping usage for older age cohorts. Moreover, if we reduce elder users to their “impairments,” we risk stereotyping them in ways that curtail design possibilities, as well as these users’ possibilities for full participation in digital life. For this reason, studies of technology users aged 60+ and their communities are necessary to shed light on the multifaceted needs of older age cohorts, and the interventions into technology design, documentation, and education that can help them reach their digital goals. </div><div><br></div><div>To build an understanding of the unique technology use of a group of the oldest Americans (aged 75+), as well as to assess their needs and desires for digital engagement, I conducted interviews and observations with computer users in a senior living community. Data collection revealed a great diversity of computing purposes and activities, ranging from social functions such as email and messaging, to managing finance and medicine, to art and design applications, and beyond. Moreover, participants’ accounts of how and where they developed their computing skills shed light on their motivations for engaging with technology, as well as their fears of technology’s intrusiveness. Analysis of participants’ performance on a series of digital tasks yielded insights into physical and cognitive factors, as well as a clear divide in forms of knowledge and mental models that older adults draw upon when attempting to engage with technology. To conclude, I provide recommendations for technology design and education, as well as future research to account for age as a factor mediating user experience.</div>

<p>Alzheimer’s disease (AD) is a degenerative disease with progressive deterioration of neural networks in the brain. Fractal dimension analysis (FD) of resting state blood oxygen level dependent (BOLD) signals acquired using functional magnetic resonance imaging (fMRI) allows us to quantify complex signalling in the brain and may offer a window into the network erosion. This novel approach can provide a sensitive tool to examine early stages of AD. As AD progresses, we expect to see a reduction in brain connectivity and signal complexity concurrent with biochemical changes (e.g. altered levels of N-acetyl aspartate (NAA), myoinositol (mI) and glutamate as measured using magnetic resonance spectroscopy, MRS), volumetric changes and abnormally high levels of brain iron.</p> <p>Over a series of 4 studies we examined the relationship of BOLD signal complexity and functional connectivity with documented MRI markers of pathology in AD (n=38) as compared to normal controls (NC) (n=16). AD subjects were in early stage of illness (mild to moderate impairment on the mini mental state exam, MMSE). We validated the temporal (short term (within minutes) and longer term (over a number of months)) consistency of FD measurement and choice of BOLD acquisition method (spiral vs. EPI), provided MRI sequence repeat time (TR) was kept constant. FD reduction (decrease in signal complexity) correlated with worsening pathological values on MRS (­NAA decrease and mI increase) and with a decrease in functional connectivity. This demonstrates that FD (signal complexity) reduces in proportion to AD severity. FD reduction is connected to functional connectivity measured through resting state network (RSN) analysis suggesting the reduction in FD relates to neuronal loss rather than altered vascularity. The narrow range of cognitive impairment (such as scores on the MMSE or the clinical dementia rating scale, CDR) likely precluded correlation between these measures and FD or RSN. Functional connectivity (RSN) was also reduced when brain iron levels were increased within certain network nodes (posterior cingulate cortex and lateral parietal cortex). Therefore iron deposition may play a role in network disruption of AD brains.</p> <p>The overall conclusion of this thesis is that signal complexity of BOLD fMRI signals, as measured with FD, may detect early pathology in the progression of AD. FD can detect neuronal changes in deep brain structures before volume loss in these structures and before significant changes in MRS markers were detectable between the AD and NC groups. An FD change mirrors disruptions in functional connectivity but detection is not limited to RSN nodes in the brain. This novel approach could further our understanding of AD and may be applied to other pathologies of the brain.</p> / Doctor of Philosophy (PhD)

The main goal of the thesis entitled "The selected methods of social work with clients self-non sufficient in health care facilities" was to describe and to analyze methods used in activation of the elderly suffering from dementia. It draws a comparison of different settings and explores workers's attitude to the methods of activation. The text of the thesis was mapped out into five chapters. The first chapter was set into the context of old age and ageing. The second chapter is concerned with the issues of self-sufficiency and dependency of old age and other related issues. The topic of the third chapter is old age in relation with memory. It defines memory and memory disorders in the elderly suffering from dementia. The fourth chapter is crucial and gives an idea of non-pharmacological and other possible activities which are eligible for application in practice and are intended to reduce cognitive disorders of cognitive functions and behavior disorders. The theoretical part enters into research carried out in four facilities which care for clients with dementia. The research section is represented by a qualitative research where methods of a half structured interview and observation were opted for. The interviews were realized with eight practicing experts. The outcomes gathered from the...
