The links between head injury and homelessness: A qualitative study

Background and aims: Head injury (HI) is a cause of cognitive impairment within the homeless population (Hwang et al, 2008). One study reported that over a 30-year period, the prevalence of hospitalised HI was 5.4 times higher in the homeless than in the general population (McMillan et al, 2015). This study explores the perceptions of homeless adults who have sustained a HI and their views regarding the relevance of HI to their homeless status. Methods: Participants were seven homeless adults with a moderate or severe HI. They were asked to talk about their journey to homelessness and in particular, to reflect on any perceived links between HI and their homeless status. The data were analysed using Interpretative Phenomenological Analysis (IPA). Results and conclusions: Emerging themes included: impairment following HI; substance misuse, feeling let down by services and difficult relationships with family. Evidence for the role of HI in precipitating and maintaining homelessness was found. Despite this, co-morbid difficulties complicate the picture. Four out of seven participants viewed substance misuse as their primary difficulty. This illustrates the need for in-depth assessment within this population in order to ensure that difficulties are fully understood and that the correct supports/ interventions are offered.

Falls and other geriatric syndromes in Blantyre, Malawi: a community survey of older adults

Background The prevalence of geriatric syndromes (falls, immobility, intellectual or memory impairment, and incontinence) is unknown in many resource-poor countries. With an aging population such knowledge is essential to develop national policies on the health and social needs of older people. The aim of this study was to provide a preliminary survey to explore the prevalence of falls and other geriatric syndromes and their association with known risk factors in people aged > 60 years in urban Blantyre, Malawi. Methods This was a cross-sectional, community survey of adults aged > 60 years. Subjects were recruited at home or in the waiting areas of chronic care clinics. They were interviewed to complete a questionnaire on ageassociated syndromes and comorbid problems. The Abbreviated Mental Test (AMT) and Timed Up and Go (TUG) tests were carried out. Results Ninety-eight subjects were studied; 41% reported falling in the past 12 months, 33% of whom (13% of all subjects) were recurrent fallers. Twenty-five percent reported urine incontinence, 66% self-reported memory difficulties, and 11% had an AMT score < 7. A history of falling was significantly associated with urine incontinence (p=0.01), selfreported memory problems (p=0.004) and AMT score < 7 (p=0.02). Conclusions Geriatric syndromes, including falls, appear to be prevalent in older people in Blantyre, Malawi. Falling is associated with cognitive impairment and urinary incontinence. There is an urgent need for more understanding of geriatric problems in this setting to develop national policies on health and social needs of older people. It is likely that many of the contributory factors to falls would be amenable to multifactorial interventions similar to those found to be effective in developed countries.

Beers versus STOPP criteria in polyharmacy community-dwelling older patients

Objective: To assess potentially inappropriate prescribing (PIP) using Beers (2012 version) and STOPP (2008 version) criteria in polypharmacy, community-dwelling, older patients. Methods: From the information collected in the invoicing data of the prescriptions and the electronic medical records, a sample was selected of 223 ≥ 65-year-old patients who were taking simultaneously 10 or more drugs per day. Beers and STOPP criteria were separately applied, and the results obtained with the two methods were compared. Results: A total of 141 (63.2%) patients presented at least one Beers criterion. The two most frequently observed Beers criteria independent of diagnosis were the use of benzodiazepines and the use of non-COX-2-selective non-steroidal anti-inflammatory drugs. With regard to Beers criteria considering diagnosis, the most frequent were the use of anticholinergic drugs in patients with lower urinary tract symptoms or benign prostatic hyperplasia, and the use of benzodiazepines, antipsychotics, Zolpidem or H2-antihistamines, in patients with dementia or cognitive impairment. A total of 165 (73.9%) patients had at least one PIP according to the STOPP criteria. Duplicate drug classes and long-term use of long-acting benzodiazepines were the two most frequent STOPP criteria. Discussion: Our study identified a high frequency of PIP in poly-medicated community-dwelling older patients. Simultaneous application of Beers and STOPP criteria represents a useful tool to improve prescribing in this population group.

Salud integral y derechos del adulto mayor. Estudio en la comunidad de Maluay, el Valle

El 6.5% de la población ecuatoriana son adultos mayores, falleciendo alrededor de 34.000 cada año. Su bienestar constituye una preocupación política y social, pero sus derechos muchas veces son vulnerados por una sociedad que vive su cotidianidad en lucha contra el más fuerte y olvida extender la mano a los protagonistas del pasado, quienes muestran un impacto negativo en su salud integral. METODOLOGÍA: Estudio descriptivo en 40 adultos mayores de la comunidad de Maluay (95,2%) en quienes se valoró la salud integral a través del uso de formularios del MSP. También, se aplicaron técnicas documentales y de observación directa para recolección de datos. RESULTADOS La mayoría son mujeres entre 65 y 74 años, media de 69.5 años, analfabetos/as (93%), sin actividad o dedicados al trabajo de campo y no cuentan con agua potable. Sus condiciones se ven afectadas por enfermedades crónicas degenerativas que les confiere cierto grado de discapacidad. Presentan riesgo de desnutrición (73%), déficit cognitivo (65%), casi la mitad con cierta dificultad en el equilibrio y la marcha. Aunque sean independientes en las actividades básicas de la vida diaria, necesitan cierta ayuda en actividades instrumentales. Socialmente son aceptados (78%). DISCUSIÓN La calidad de vida de los adultos mayores, especialmente en sectores rurales no es apropiada pese al respaldo de políticas públicas. El conocimiento de los factores de riesgo y sus necesidades para elaborar estrategias de prevención y promoción con un enfoque holístico debe ser la prioridad en la Salud Pública, pues atravesamos una transición que se dirige a los riesgos emergentes asociados con la industrialización, la urbanización y el envejecimiento poblacional

Ansiedade pós acidente vascular cerebral

Se entendemos o Acidente vascular cerebral como um acontecimento incapacitante da vida dos pacientes, poderemos compreender as alterações comportamentais e emocionas que este provoca. No entanto, poucos estudos têm sido realizados acerca desta temática, tendo assim este estudo como objetivo verificar se existe uma associação clara entre a ansiedade e um determinado tipo de AVC. Aplicou-se a escala de Montereal, o State-Trait Anxiety lnventory e o Inventario Neuropsiquiátrico numa amostra constituída por pacientes que tenham sofrido AVC no período de três meses a um ano, e num grupo controlo. Os resultados mostram que não existem diferenças significativas no que respeita à ansiedade nos pacientes com AVC anterior. Conclui-se que não existe um aumento de ansiedade, mas que os défices visuo-espaciais e atencionais são mais significativos no AVC anterior. / ABSTRACT: lf we recognize Stroke as an event that can incapacitate the patients' life, we can comprehend the behaviour and emotional changes that this provokes. One of the psychiatric symptoms usually associated to Stroke is anxiety. However, few studies have been made concerning this matter, being the purpose of this study to verify if a clear association exists between anxiety and a certain type of Stroke. The Montereal Cognitiva Assessment, State-Trait Anxiety lnventory, and Neuropsychiatric lnventory were applied in a sample consisting of patients that have suffered Stroke in the period of three months to one year, and in a control group. The results show no significant differences in what regards to anxiety in patients with previous Stroke. We conclude that there is no increase in anxiety after stroke, but cognitive deficits in visual-spatial and attentional are most significant in subjects with previous stroke.

Influência dos factores de risco vascular no desempenho cognitivo

O objetivo deste estudo consiste em verificar até que ponto os sujeitos com fatores de risco vascular acentuados apresentam alterações no seu desempenho cognitivo, na ausência de lesão vascular conhecida. Para tal, os défices apresentados por estes foram comparados com sujeitos que se encontram na fase pós-aguda do AVC (Acidente Vascular Cerebral) e sujeitos do grupo de controlo. Os défices cognitivos foram avaliados através de uma bateria de testes neuro psicológicos estandardizados, nos quais se avaliou a atenção, memória e funções executivas. Os resultados parecem confirmar a existência de um défice significativo nos sujeitos com fatores de risco em relação ao grupo de controlo, no que diz respeito à memória verbal e visual a curto-prazo e capacidade de aprendizagem. Assim, com base nos resultados podemos inferir a possibilidade de que os fatores de risco, por si só, podem causar determinado tipo de défice cognitivo. / ABSTRACT: The aim of this study is to determine the extent to which individuals with vascular risk factors have pronounced changes in their cognitive performance, in the absence of known vascular injury. For this purpose, the deficits presented by these subjects were compared to those who are in the post-acute stage of the Stroke and subjects in the control group. Cognitive deficits were assessed using a battery of standardized neuro¬ psychological tests, in which it was assessed attention, memory and executive functions. The results seem to confirm the existence of a significant deficit in subjects with risk factors in relation to the control group in what regards to short-term verbal and visual memory and learning ability. Therefore, based on the results we may imply the possibility that risk factors by themselves can cause certain types of cognitive impairment.

Development of the Andalusian Registry of Patients Receiving Community Case Management, for the follow-up of people with complex chronic diseases.

Background: Complex chronic diseases are a challenge for the current configuration of Health services. Case management is a service frequently provided for people with chronic conditions and despite its effectiveness in many outcomes, such as mortality or readmissions, uncertainty remains about the most effective form of team organization, structures, and the nature of the interventions. Many processes and outcomes of case management for people with complex chronic conditions cannot be addressed with the information provided by electronic clinical records. Registries are frequently used to deal with this weakness. The aim of this study was to generate a registry-based information system of patients receiving case management to identify their clinical characteristics, their context of care, events identified during their follow-up, interventions developed by case managers, and services used. Methods and design: The study was divided into three phases, covering the detection of information needs, the design and its implementation in the healthcare system, using literature review and expert consensus methods to select variables that would be included in the registry. Objective: To describe the essential characteristics of the provision of ca re lo people who receive case management (structure, process and outcomes), with special emphasis on those with complex chronic diseases. Study population: Patients from any District of Primary Care, who initiate the utilization of case management services, to avoid information bias that may occur when including subjects who have already been received the service, and whose outcomes and characteristics could not be properly collected. Results: A total of 102 variables representing structure, processes and outcomes of case management were selected for their inclusion in the registry after the consensus phase. Total sample was composed of 427 patients, of which 211 (49.4%) were women and 216 (50.6%) were men. The average functional level (Barthel lndex) was 36.18 (SD 29.02), cognitive function (Pfeiffer) showed an average of 4.37 {SD 6.57), Chat1son Comorbidity lndex, obtained a mean of 3.03 (SD 2.7) and Social Support (Duke lndex) was 34.2 % (SD 17.57). More than half of patients include in the Registry, correspond lo immobilized or transitional care for patients discharged from hospital (66.5 %). The patient's educational level was low or very low (50.4%). Caregivers overstrain (Caregiver stress index), obtained an average value of 6.09% (SD 3.53). Only 1.2 % of patients had declared their advanced directives, 58.6 had not defined the tutelage and the vast majority lived at home 98.8 %. Regarding the major events recorded at RANGE Registry, 25.8 % of the selected patients died in the first three months, 8.2 % suffered a hospital admission at least once time, 2.3%, two times, and 1.2% three times, 7.5% suffered a fall, 8.7% had pressure ulcer, 4.7% had problems with medication, and 3.3 % were institutionalized. Stroke is the more prevalent health problem recorded (25.1%), followed by hypertension (11.1%) and COPD (11.1%). Patients registered by NCMs had as main processes diabetes (16.8%) and dementia (11.3 %). The most frequent nursing diagnoses referred to the self-care deficit in various activities of daily living. Regarding to nursing interventions, described by the Nursing Intervention Classification (NIC), dementia management is the most used intervention, followed by mutual goal setting, caregiver and emotional support. Conclusions: The patient profile who receive case management services is a chronic complex patient with severe dependence, cognitive impairment, normal social support, low educational level, health problems such as stroke, hypertension or COPD, diabetes or dementia, and has an informal caregiver. At the first follow up, mortality was 19.2%, and a discrete rate of readmissions and falls.

Hyperactivations frontales en mémoire de travail dans le trouble cognitif léger

Des études récentes ont rapporté que les individus âgés avec un trouble cognitif léger (TCL) ont de plus grandes activations en lien avec la réalisation d’une tâche cognitive que des personnes âgées saines. Des auteurs ont proposé que ces hyperactivations pourraient refléter des processus de plasticité cérébrale compensatoires ayant lieu pendant la phase précoce de la maladie d’Alzheimer. Des processus de compensations fonctionnelles pourraient émerger en réponse à une perte d’intégrité structurelle dans les régions du cerveau normalement requises pour compléter une tâche. Dans ce mémoire, j’ai évalué cette hypothèse chez des personnes avec TCL en faisant appel à une tâche de mémoire de travail comportant plusieurs niveaux de difficulté ainsi qu’aux techniques d’imagerie par résonnance magnétique (IRM) structurelle et fonctionnelle. Des analyses de régression multiples ont été utilisées afin d’identifier les régions cérébrales dont l’activité variait en fonction de l’intégrité neuronale telle que définie par le volume de l’hippocampe. Les valeurs estimées des paramètres du signal de ces régions furent ensuite extraites afin de procéder à des analyses corrélationnelles sur la performance ainsi que sur le volume de différentes structures cérébrales. Les résultats indiquent des hyperactivations dans les régions frontales droites chez les participants TCL souffrant d’une plus grande atteinte neuronale. De plus, le niveau d’activation est négativement corrélé au volume de structures frontales et pariétales. Ces résultats indique la présence d’une hyperactivation compensatoire dans la phase du TCL associée à la réalisation d’une tâche de mémoire de travail.

The Role of Existential Beliefs Within the Relation of Centenarians’ Health and Well-Being

The purpose of this study was to explore the role of existential beliefs in mediating the influence of health on centenarians' well-being. A total of 80 centenarians (mean age 101.1; SD = 1.3; 81.3 % women) with no/minor cognitive impairment were included. The OARS questionnaire for diseases and functional capacity (ADL, IADL), the Satisfaction with Life Scale, and the existential beliefs subscale were used for data collection. The findings suggest that existential resources are a crucial element for mitigating the impact of health constraints in subjective well-being in this population. Appropriate models of intervention for very old age that recognize the importance of religion, spirituality, and meaning of life are to be considered.

Effectiveness of non-pharmacological interventions to prevent falls in older people: a systematic overview. The SENATOR Project ONTOP Series

Background: Falls are common events in older people, which cause considerable morbidity and mortality. Non-pharmacological interventions are an important approach to prevent falls. There are a large number of systematic reviews of non-pharmacological interventions, whose evidence needs to be synthesized in order to facilitate evidence-based clinical decision making. Objectives: To systematically examine reviews and meta-analyses that evaluated non-pharmacological interventions to prevent falls in older adults in the community, care facilities and hospitals. Methods: We searched the electronic databases Pubmed, the Cochrane Database of Systematic Reviews, EMBASE, CINAHL, PsycINFO, PEDRO and TRIP from January 2009 to March 2015, for systematic reviews that included at least one comparative study, evaluating any non-pharmacological intervention, to prevent falls amongst older adults. The quality of the reviews was assessed using AMSTAR and ProFaNE taxonomy was used to organize the interventions. Results: Fifty-nine systematic reviews were identified which consisted of single, multiple and multi-factorial non-pharmacological interventions to prevent falls in older people. The most frequent ProFaNE defined interventions were exercises either alone or combined with other interventions, followed by environment/assistive technology interventions comprising environmental modifications, assistive and protective aids, staff education and vision assessment/correction. Knowledge was the third principle class of interventions as patient education. Exercise and multifactorial interventions were the most effective treatments to reduce falls in older adults, although not all types of exercise were equally effective in all subjects and in all settings. Effective exercise programs combined balance and strength training. Reviews with a higher AMSTAR score were more likely to contain more primary studies, to be updated and to perform meta-analysis. Conclusions: The aim of this overview of reviews of non-pharmacological interventions to prevent falls in older people in different settings, is to support clinicians and other healthcare workers with clinical decision-making by providing a comprehensive perspective of findings.

Registro de pacientes con distrofinopatías en Colombia

INTRODUCCIÓN. La distrofia muscular de Duchenne es una enfermedad neuromuscular con una herencia recesiva ligada al X que afecta a 1 de cada 3500 niños nacidos vivos. Se produce por mutaciones en el gen DMD que codifica para la distrofina. Se caracteriza por manifestaciones clínicas variables típicas de una distrofia muscular proximal progresiva. OBJETIVO. Realizar el primer registro en Colombia de los pacientes identificados con distrofinopatías, teniendo en cuenta características clínicas y paraclínicas, así como las mutaciones causales de esta patología. METODOLOGÍA Es un estudio descriptivo, transversal, de la revisión de historias clínicas de los pacientes con diagnóstico de DMD atendidos en la consulta de Genética de la Universidad del Rosario durante los años 2006 a 2015. RESULTADOS Se identificaron 99 pacientes, de los cuales 56 (56,56%) corresponden al fenotipo Duchenne y 12 (12,12%) al Becker. No fue posible clasificar a 31 pacientes (31,3%) por falta de datos clínicos. La edad de inicio de los síntomas fue en promedio de 4,41 años. Las mutaciones más frecuentes fueron las deleciones (69%), seguidas por las mutaciones puntuales(14%), las duplicaciones (11%) y por otras mutaciones (4%). CONCLUSIONES Este registro de distrofinopatías es el primero reportado en Colombia y el punto de partida para conocer la incidencia de la enfermedad, caracterización clínica y molecular de los pacientes, garantizando así el acceso oportuno a los nuevos tratamientos de medicina de precisión que permitan mejorar la calidad de vida de los pacientes y sus familias.

Relación entre atrofia cortical difusa y desempeño cognitivo : estudio en población mayor de 60 años en un hospital universitario en la ciudad de Bogotá

El presente trabajo tuvo como objetivo evaluar la existencia de la relación entre la atrofia cortical difusa objetivada por neuroimagenes cerebrales y desempeños cognitivos determinados mediante la aplicación de pruebas neuropsicológicas que evalúan memoria de trabajo, razonamiento simbólico verbal y memoria anterógrada declarativa. Participaron 114 sujetos reclutados en el Hospital Universitario Mayor Méderi de la ciudad de Bogotá mediante muestreo de conveniencia. Los resultados arrojaron diferencias significativas entre los dos grupos (pacientes con diagnóstico de atrofia cortical difusa y pacientes con neuroimagenes interpretadas como dentro de los límites normales) en todas las pruebas neuropsicológicas aplicadas. Respecto a las variables demográficas se pudo observar que el grado de escolaridad contribuye como factor neuroprotector de un posible deterioro cognitivo. Tales hallazgos son importantes para determinar protocoles tempranos de detección de posible instalación de enfermedades neurodegenerativas primarias.

Actitudes hacia la Enfermedad del Alzheimer según el género y la edad de adultos colombianos

La enfermedad de Alzheimer (EA) es la demencia más frecuente y su prevalencia continúa en aumento tanto en Colombia como en el mundo. Esta investigación tuvo como objetivo explorar si las actitudes hacia la EA varían según la edad y género de 450 personas adultas colombianas. Se realizó un estudio exploratorio de corte transversal en el que se aplicó un cuestionario autodiligenciado. Se encontró que efectivamente hay algunas diferencias según la edad y el género en el componente cognoscitivo (creencias y conocimiento) y conductual (intención conductual y conducta) de las actitudes; y diferencias según el género en el componente afectivo. Se concluye que los conocimientos sobre la EA son escasos, que la tristeza es la emoción predominante hacia la EA y que es un tema de interés en el que predomina la idea de que afecta especialmente la memoria. Se discutieron los resultados reconociendo que esta es una aproximación inicial a las actitudes hacia la EA.
