Actions to be taken for improving functional prognosis in dementia
The growing incidence of dementia has led to an increased need for specialized care and higher health and social costs. Functional decline is the main cause of dementia complications. Per definition, dementia diagnosis and severity stratification require a certain degree of functional impairment [1]. Therefore, it is important to determine strategies to prevent functional deterioration in both, general population and especially people with dementia.
The number of older adults with some degree of disability will triple by 2050 due to the increase in the aging population and the prevalence of age-related diseases that lead to functional impairment [2]. Therefore, functional impairment and disability in old people are increasingly becoming a major public health concern. Furthermore, functional impairment severely impairs quality of life and consumes a large proportion of the public health resources, creating an important burden for health care systems.
It is well known that functional loss and disability in dementia are the main consequences of cognitive decline. Therefore, most of the efforts in dementia management have been directed to stop or reverse cognitive decline. However, functional loss and disability are also the consequence of other conditions that are common in old age and comorbid with dementia, such as frailty, sarcopenia, malnutrition, falls, pulmonary or cardiovascular diseases, polypharmacy, depression, and neuropsychiatric symptoms (NPS) [3].Q3Q2The growing incidence of dementia has led to an increased need for specialized care and higher health and social costs.

Oral health and self-rated health in community-dwelling older adults in Colombia
Background
The relationship between oral health and specific health conditions, such as cardiovascular disease or cognitive impairment, has been extensively studied. However, the effect of oral health status on self-rated health has not been assessed. This could be relevant in older people considering that poor self-rated health status and oral diseases are highly prevalent in this population. The aim of this study was to determine the association between different parameters of oral health and self-rated health status (SRHS) in Colombian community-dwelling older adults.
Methods
This is a secondary analysis of the SABE-Colombia study performed in 2015. The dependent variable was defined as the SRHS status assessed by the question "Compared with other people, your age: Do you consider your health status to be better, equal, or worse?” We considered four independent variables: total edentulism considering the high prevalence in older people, the GOHAI score to assess self-rated oral health, and the use of fixed and removable dental prostheses as potential modifiers of oral health. An adjusted ordinal logistic regression was performed by each independent variable.
Results
After the exclusion of missing data, 17,945 persons were included in the final analysis. A total of 10.6% reported worse SRHS, 37.6% reported equal SRHS, and 51.6% reported better SRHS. The worse SRHS group was older and had a higher proportion of dependence, cognitive impairment, and depressive symptoms. The frequency of total edentulism and the lower mean score of GOHAI were significant in the worse SHRS group. An ordinal logistic regression for each independent variable was performed, finding that edentulism increases the probability of worse SHRS, while the GOHAI and use of removable or fixed dental prostheses increase the probability of better SRHS.
Conclusion
We found an association between total edentulism, GOHAI Index, the use of dental prostheses (both removable and fixed), and self-rated health status, showing the relevance of oral health status to self-rated health status independent of comorbidities and geriatric syndromes. This result supports the inclusion of oral health evaluation in comprehensive geriatric assessment.
Peer Review reportsQ1Fondo
Se ha estudiado ampliamente la relación entre la salud bucal y afecciones de salud específicas, como las enfermedades cardiovasculares o el deterioro cognitivo. Sin embargo, no se ha evaluado el efecto del estado de salud bucal sobre la salud autovalorada. Esto podría ser relevante en las personas mayores, considerando que el mal estado de salud autovalorado y las enfermedades bucales son altamente prevalentes en esta población. El objetivo de este estudio fue determinar la asociación entre diferentes parámetros de salud bucal y el estado de salud autoevaluado (ESSR) en adultos mayores colombianos que viven en comunidades.
Métodos
Este es un análisis secundario del estudio SABE-Colombia realizado en 2015. La variable dependiente se definió como el estado de SRHS evaluado mediante la pregunta "En comparación con otras personas, tu edad: ¿Consideras que tu estado de salud es mejor, igual o ¿peor?" Se consideraron cuatro variables independientes: edentulismo total considerando la alta prevalencia en personas mayores, el puntaje GOHAI para evaluar la salud bucal autovalorada y el uso de prótesis dentales fijas y removibles como potenciales modificadores de la salud bucal.Se realizó una regresión logística ordinal ajustada. por cada variable independiente.
Resultados
Después de excluir los datos faltantes, se incluyeron en el análisis final 17.945 personas. Un total de 10,6% reportó peor SRHS, 37,6% reportó igual SRHS y 51,6% reportó mejor SRHS. El grupo con peor SRHS era de mayor edad y tenía una mayor proporción de dependencia, deterioro cognitivo y síntomas depresivos. La frecuencia de edentulismo total y la puntuación media más baja de GOHAI fueron significativas en el grupo con peor SHRS. Se realizó una regresión logística ordinal para cada variable independiente, encontrando que el edentulismo aumenta la probabilidad de peor SHRS, mientras que el GOHAI y el uso de prótesis dentales fijas o removibles aumentan la probabilidad de mejor SRHS.
Conclusión
Encontramos una asociación entre el edentulismo total, el índice GOHAI, el uso de prótesis dentales (tanto removibles como fijas) y el estado de salud autoevaluado, lo que muestra la relevancia del estado de salud bucal para el estado de salud autoevaluado independientemente de comorbilidades y síndromes geriátricos. Este resultado respalda la inclusión de la evaluación de la salud bucal en la evaluación geriátrica integral.

Benzodiazepines and antidepressants: Effects on cognitive and functional decline in Alzheimer's disease and Lewy body dementia
Objectives
We aim to study the effects of the prescription of benzodiazepines and antidepressants on cognitive and functional decline in older adults living with Alzheimer's disease (AD) and Lewy body dementia (LBD) over a 5-year follow-up.
Methods
This is a longitudinal analysis of a Norwegian cohort study entitled “The Dementia Study of Western Norway” (DemVest). We included 196 patients newly diagnosed with AD (n = 111) and LBD (n = 85), followed annually for 5 years. Three prescription groups were defined: only benzodiazepines (BZD), only antidepressants (ADep), and the combination of benzodiazepines and antidepressants (BZD-ADep). Linear mixed-effects models were conducted to analyze the effect of the defined groups on the outcomes. The outcomes were functional decline, measured by the Rapid Disability Rating Scale—2, and cognition measured with the Mini-Mental State Examination.
Results
Prescription of the combination of benzodiazepines and antidepressants in LBD was associated with faster functional decline. In AD, the prescription of BZD and BZD-ADep was associated with greater functional deterioration. ADep alone did not show positive or negative significant associations with the studied outcomes.
Conclusions
BZD and especially the combination of BZD and ADep are associated with functional decline in AD and LBD and should be used cautiously.publishedVersio
Factores asociados con el deterioro funcional en adultos mayores mexicanos
Introducción. El deterioro funcional está relacionado con muchos resultados adversos.
Objetivo. Explorar la relación de los factores sociodemográficos, médicos y psicológicos con la incidencia del deterioro funcional en los adultos mayores mexicanos.
Materiales y métodos. Se analizaron los datos de las cohortes de 2012 y 2015 de la encuesta del Estudio Mexicano de Salud y Envejecimiento. Se excluyeron los participantes con discapacidad funcional en el período de referencia (2012). Se evaluó de forma individual el deterioro funcional en las actividades básicas de la vida diaria (AVD) y en las instrumentales (AIVD).
Resultados. Se encontró que el dolor, las comorbilidades, el nivel educativo, el estatus socioeconómico y la depresión se asociaban independientemente con el deterioro de las AVD. El deterioro de las AIVD se asoció con la edad, la educación deficiente, las comorbilidades, la depresión y el deterioro cognitivo.
Conclusiones. La edad, el sexo, el estado financiero, el nivel educativo, el dolor y el número de comorbilidades se asociaron con la incidencia del deterioro funcional. El dolor tuvo una mayor asociación con la incidencia del deterioro funcional en las AVD a los tres años, en comparación con el deterioro cognitivo. El estudio del deterioro funcional por dominios permitió recabar información más detallada para determinar los factores que pueden intervenirse con el objetivo de reducir la incidencia del deterioro funcional y la dependencia.publishedVersio
Gait speed as a mediator of the effect of sarcopenia on dependency in activities of daily living
Background Sarcopenia in older adults is strongly associated with an increase in dependency in activities of daily living (ADL)
and with a decline in gait speed. Interestingly, gait speed has been shown to independently predict mortality. In this context,
our study aimed to explore the mediator role of gait speed on the relationship between sarcopenia and dependency in ADL.
Methods A cross-sectional study was conducted in Colombia, 19 705 older adults with a mean age of 70 years, 55.6%
women, 16.1% with sarcopenia, and 14.7% mild, moderate, or severe dependency in ADL, according to ‘SABE Survey 2015’.
Sarcopenia was assessed by calf circumference and ADL dependence through the Barthel Index. Gait speed was measured over
a distance of 3 m. The association between sarcopenia condition and gait speed and dependency level was analysed by linear
regression adjusted by covariates. To examine whether gait speed mediated the association between sarcopenia and dependence
components of physical function, simple mediation models were generated using ordinary least squares with the macro
PROCESS version 3.2, adjusted for age, sex, and body mass index (BMI).
Results Significant differences (P < 0.05) were found in gait speed and dependency in ADL between the sarcopenia and nonsarcopenia
groups after adjusting for age, sex, and BMI. BMI was significantly higher in the non-sarcopenia group whereas dependency
was significantly higher in the sarcopenia group (19.6% vs. 13.8%). Results from mediation model regression analysis
indicated a significant and direct detrimental effect of sarcopenia on dependency in ADL (β = 0.05; P < 0.001), and a significant
indirect effect of gait speed on the direct effect ( 0.009 to 0.004).
Conclusions The negative effect of sarcopenia on functional dependence was mediated by the gait speed. Therefore, gait
speed may positively influence the detrimental effect of sarcopenia for dependency, after adjusting for age, gender, and
BMI. Consequently, physical exercise should be promoted and focused to circumvent the gait speed decline associated with
age in older people with sarcopenia

Statin and risk of falls in the elderly : a sytematic review of the literature
Antecedentes: La alta incidencia de eventos cardiovasculares en la población anciana ha demostrado la eficacia de las estatinas en la reducción de la mortalidad por eventos coronarios; sin embargo, se han producido efectos adversos, tales como mialgia, miopatía, mionecrosis, sin mencionar las caídas como consecuencia de dano˜ muscular con el uso de estatinas. Objetivo: El objetivo de este estudio es realizar una revisión sistemática para evaluar la literatura sobre la asociación entre el uso de estatinas y el riesgo de caídas. Métodos: Las bases de datos que se incluyeron (PubMed y SCOPUS) con artículos publicados entre enero de 2000 y mayo de 2016. Los términos MESH utilizados para la búsqueda fueron «FALLS» AND «STATIN». Los estudios seleccionados incluyeron cohortes de población de la comunidad (> 50 anos) ˜ y fue analizado siguiendo las recomendaciones metodológicas SIGN (Scottish Intercollegiate Guidelines Network), ya que no se encontró ningún estudio controlado aleatorizado. Resultados: En el estudio de Ham et al. el uso de estatinas ha demostrado ser un factor protector para la presencia de caídas. En el segundo estudio realizado por Scott et al. se encontró un aumento del riesgo de caídas (p = 0,029) y un deterioro de la fuerza muscular y la calidad del músculo (valor de p = 0,033 y 0,046, respectivamente). En el tercer estudio Haerer et al. se encontró un mayor riesgo de caídas (p = 0,63). Conclusiones: La evidencia disponible no permite determinar la asociación entre el uso de estatinas y el riesgo de caídas, aunque sí se encontró asociación con el compromiso de algunos determinantes de la función muscularQ3Artículo original317-321Background: With the high incidence of cardiovascular events in the elderly population the effectiveness of statins in reducing mortality from coronary events has been demonstrated. However, there have been adverse effects, such as myalgia, myopathy, myonecrosis, not to mention the falls as a result of muscle damage with statin use. Objective: The purpose of this study is to conduct a systematic review to assess the literature on the association between statin use and the risk of falls. Methods: The databases that were included PUBMED AND SCOPUS, with articles published from January 2000 to May 2016. The MESH terms used for the search were “FALLS” AND “STATIN”. Selected studies included cohort populations from the community (> 50 years old), and analysed using the Scottish Intercollegiate (SIGN) methodology guidelines, as no randomised controlled study was found. Results: In the study by Ham et al., statin use was shown to be a protective factor for presence of falls. In the second study by Scott et al., there was an increased risk of falls (P = .029) and an impairment in muscle strength and quality muscle (P = .033 and P = .046, respectively). In the third study Haerer et al., found an increased risk of falls (P = .63). Conclusions: The association between use of statins and risk of falls could not be determined with the available evidence, although an association with the involvement of some determinants of muscular function was foun
Body mass index, performance on activities of daily living and cognition: analysis in two different populations
Background
With this study, we aim to determine the associations of the different categories of the body mass index (BMI) with activities of daily living (ADL) and cognitive performance in two different populations living in the community; Colombian and South Korean older adults.
Methods
We performed a cross-sectional analysis of two surveys separately; The Survey on Health, Well-Being, and Aging in Colombia (SABE) (n = 23,343) and the Korean Longitudinal Study of aging (KLoSA) (n = 4556). Participants older than 50 years were selected from rural and urban areas achieving a representative sample. Here we investigated the association between BMI categories with function using zero-inflated negative binomial regressions, and with cognition using logistic regression models.
Results
After adjustment, in Colombia, underweight was associated with an impaired score on the Mini-mental State Examination (MMSE) and worse performance in the instrumental activities of daily living (IADL). Also, being overweight was associated with a better score on the MMSE and the IADL. For both outcomes education level significantly influenced the predictions. In South Korea, there were no significant associations for cognition, IADL, or basic activities of daily living (BADL).
Conclusions
In the Colombian population, underweight, was associated with reduced cognitive performance and daily functioning. Additionally, being overweight but not obese was associated with better cognition and daily functioning. In South Korea, there were no significant associations between BMI and cognition, IADL, or BADL.publishedVersio
Motoric Cognitive Risk Syndrome: Prevalence and Cognitive Performance. A cross-sectional study
Background
Motoric Cognitive Risk Syndrome (MCR) is a predementia stage where slow gait speed and subjective memory complaints are present. The purpose of this study was to estimate the prevalence of MCR and assess its relationship with sociodemographic factors and chronic conditions.
Methods
This is a secondary analysis of the SABE Colombia study conducted in 2015. The analytic sample consisted of 17·577 participants. After determining MCR prevalence, logistic regression was performed to examine the correlates of MCR.
Findings
The prevalence of MCR was 10·71 %. The median age was 71 years and women composed 74·63 % of the MCR group. After adjusting for confounding variables MCR was associated with increasing age (OR 1·69, CI 1·43 - 1·92), no or low education (OR 1·99, CI 1·67- 2·37), MMSE (OR 0·93, CI 0·91 - 0·95) and chronic conditions such as mental disorders (OR 1·36, CI 1·11-1·67), history of myocardial infarction (OR 1·24, CI 1·04 - 1·47), hypertension (OR 1·23, CI 1·08 - 1·40) and diabetes (OR 1.18, CI 1.01 – 1.37).
Interpretation
This study found a prevalence of 10·71 % of MCR in Colombian older adults. Additionally, MCR was associated with chronic conditions and sociodemographic factors identified in prior studies. These results increase the awareness of a novel predementia stage whose identification can be performed by clinicians in the outpatient clinic, minimizing the cost of a full neuropsychologic evaluation performed in a memory clinic.publishedVersio
