ABSTRACT Background: The pathogenesis of mild cognitive impairment (MCI) is multifactorial and includes the presence of genetic variants such as the ε4 allele of the apolipoprotein E gene (APOE-ε4). Association between the APOE-ε4 carrier status and deleterious structural and functional changes on magnetic resonance imaging (MRI) has been previously described in individuals with Alzheimer's disease. However, the central nervous system changes may possibly develop in earlier stages of cognitive impairment, as reflected in MCI. Objective: The objective of the study was to determine the association between APOE-ε4 carrier status and qualitative changes on MRI (medial temporal and parietal atrophy), as well as the detection of white matter hyperintensities (WMH) in older adults with MCI, in the memory clinic of a tertiary care hospital in Mexico City. Methods: A cross-sectional study of 72 adults aged 60 years or above who underwent an exhaustive clinical, neuroimaging, and neuropsychological evaluation. Multivariate logistic regression models were constructed to determine the association between APOE-ε4 carrier status and qualitative/quantitative changes on MRI. Results: Mean age was 75.2 years (± 7.2) and 64% were female. Twenty-one participants were cognitively normal and 51 had MCI. Almost 56% were APOE-ε4 carriers and were associated with medial-temporal atrophy according to the Scheltens scale (odds ratio [OR]: 20.0, 95% confidence intervals [CI]: 3.03-131.7), parietal atrophy according to the Koedam's score (OR: 6.3; 95% CI 1.03-39.53), and WMH according to the Fazekas scale (OR: 11.7, 95% CI: 1.26-108.2), even after adjusting for age, educational level, and cardiovascular risk factors. Conclusion: The APOE-ε4 carrier status was associated with medial temporal and parietal atrophy, as well as WMH. Our findings support the hypothesis suggesting the contribution of this genotype to neurodegeneration and cerebral vascular pathology.

OBJECTIVE: To identify the main severe potential drug-drug interactions in older adults with dementia and to examine the factors associated with these interactions. METHOD: This was a cross-sectional study. The enrolled patients were selected from six geriatrics clinics of tertiary care hospitals across Mexico City. The patients had received a clinical diagnosis of dementia based on the current standards and were further divided into the following two groups: those with severe drug-drug interactions (contraindicated/severe) (n=64) and those with non-severe drug-drug interactions (moderate/minor/absent) (n=117). Additional socio-demographic, clinical and caregiver data were included. Potential drug-drug interactions were identified using Micromedex Drug Reax 2.0® database. RESULTS: A total of 181 patients were enrolled, including 57 men (31.5%) and 124 women (68.5%) with a mean age of 80.11±8.28 years. One hundred and seven (59.1%) patients in our population had potential drug-drug interactions, of which 64 (59.81%) were severe/contraindicated. The main severe potential drug-drug interactions were caused by the combinations citalopram/anti-platelet (11.6%), clopidogrel/omeprazole (6.1%), and clopidogrel/aspirin (5.5%). Depression, the use of a higher number of medications, dementia severity and caregiver burden were the most significant factors associated with severe potential drug-drug interactions. CONCLUSIONS: Older people with dementia experience many severe potential drug-drug interactions. Anti-depressants, antiplatelets, anti-psychotics and omeprazole were the drugs most commonly involved in these interactions. Despite their frequent use, anti-dementia drugs were not involved in severe potential drug-drug interactions. The number and type of medications taken, dementia severity and depression in patients in addition to caregiver burden should be considered to avoid possible drug interactions in this population.

Background Depression is associated with an increased use of medical resources and reduced quality of life, cognitive functions, functionality and general health. The treatment of depression is limited by the scarcity of mental health professionals, as reflected in the mental health atlas of the World Health Organization. Method A randomised controlled trial that was not blinded was conducted. Family doctors referred patients older than 60 years who were suspected to have depression to the screening module. The PHQ-9 questionnaire, the Six-Item Screener, and previous diagnosis for psychiatric disorders were collected. Major depression was excluded. Those with a score from two to six on the PHQ-9 and with no comorbidities were referred to the Baseline Phase. A simple random process without blocking was applied. Groups of 7-10 participants engaged in weekly sessions over the course of three months. The control group was referred to their family physician. Reduction in depression score of the PHQ-9 was the main outcome. Results and discussion There were 40 patients in the control group (CG) and 41 in the intervention group (IG). 84% were women, 41% married and 41% reported at least primary education. The mean age for the GC was 69.7 years vs. 71.3 in the GI. The baseline mean MMSE score was 23.7 in the GC and 24.1 in the IG. No significant baseline differences between groups were reported. In the IG, 56% of the participants (n=23) displayed a decrease that was greater than or equal to 5 points on the PHQ-9 compared with 30% (n=12) in the control group. The CT group evidenced a marginal improvement.

Antecedentes La depresión se asocia con un aumento en el uso de los recursos médicos y reducción de la calidad de vida, funciones cognitivas, funcionalidad y la salud general. El tratamiento de la depresión está limitado por la escasez de profesionales en salud mental, como se refleja en el atlas de salud mental de la Organización Mundial de la Salud. Método Se realizó un ensayo controlado aleatorio no cegado. Los médicos familiares referían a los pacientes mayores de 60 años con sospecha de depresión al módulo de detección. Se aplicó el cuestionario PHQ-9, la prueba de escrutinio de seis ítems, y el diagnóstico previo de trastornos psiquiátricos. Se excluyó a pacientes con depresión mayor. Aquellos con una puntuación de dos a seis en el PHQ-9 y sin comorbilidades fueron remitidos a la fase basal. Se aplicó un proceso aleatorio simple sin bloquear. Se integraron grupos de 7-10 participantes en sesiones semanales durante el transcurso de tres meses. El grupo control fue remitido a su médico familiar. El resultado principal fue la reducción en la puntuación de la depresión del PHQ-9 Resultados y discusión Se estudiaron a 40 pacientes en el grupo control (GC) y 41 en el grupo intervención (GI). 84% eran mujeres, 41% casados y el 41% informó de al menos la educación primaria. La edad media para el GC fue 69.7 años vs. 71.3 en el GI. La puntuación media del MMSE fue de 23.7 en el GC y el 24.1 en el IG. No se registraron diferencias iniciales significativas entre los grupos. El 56% de los participantes del GI mostró una disminución que fue mayor que o igual a cinco puntos en el PHQ-9 en comparación con 30% del GC. El grupo CT demuestra una mejora marginal.

Objective: To determine the behavior of the Geriatric/General Oral Health Assessment Index as well as the Oral Impacts on Daily Performances as effective measures in oral-dental health related to quality of life in senior citizens in a given population. Methods: A representative sample of senior citizens entitled to medical services at the Instituto Mexicano del Seguro Social (Mexican Institute of Social Security) located in the southwest region of Mexico City. Home interviews were conducted in order to ascertain the sample's characteristics as well as the application of the Geriatric/General Oral Health Assessment Index and Oral Impacts on Daily Performances instruments. Clinical evaluation in order to determine experience of crown caries (CPO-D) and root caries CO-R). Results: A total of 531 subjects aged 60 years and over participated in the study, of which 68.4% were female. Age average (AA) was 71.4 years (7.0). Geriatric/General Oral Health Assessment Index exhibited a mean of 46.8 (6.2) and Oral Impacts on Daily Performances showed 4.1 (12.4). Subjects included in the sample had attended school for over 6 years, did not present limitations of cognitive deterioration, and were depression-free, exhibited a higher mean in Oral Impacts on Daily Performances score than those which did not present those characteristics (p < 0.05). Six or more years of schooling with paid work and depression-free subjects presented lesser Oral Impacts on Daily Performances scores when compared to those who did not. (p < 0.05) A correlation was found between the Geriatric/General Oral Health Assessment Index and filled components, functional teeth (p > 0.05). Filled and lost components and CPO-D index as well as healthy crowns and functional teeth exhibited a correlation with Oral Impacts on Daily Performances (p < 0.05). Conclusion: Geriatric/General Oral Health Assessment Index exhibited higher discrimination in the population's characteristics whereas Oral Impacts on Daily Performances showed higher correlation with the state of the dentition.

La escolaridad mayor de seis años, con una actividad laboral remunerada y sin depresión, presentaron una media menor del puntaje del Oral Impacts on Daily Performances en comparación a los que no presentaban (p < 0.05). Existe una correlación entre el Geriatric/General Oral Health Assessment Index y componentes obturados, dientes funcionales (p < 0.05). Los componentes perdidos, obturados e índice caries coronal, así como coronas sanas y dientes funcionales presentaron una correlación con el Oral Impacts on Daily Performances (p < 0.05). Conclusión: El Geriatric/General Oral Health Assessment Index tuvo mayor discriminación en las características de la población y el Oral Impacts on Daily Performances presentó mayor correlación con el estado de la dentición.

Introduction Depression in the elderly is of interest because of its relationship with increased demand for health services, as well as the low frequency of diagnosis. Objective To determine the frequency of depressive symptoms (DS) among elderly beneficiaries in Mexico City by the revised scale of depression of the Center for Epidemiologic Studies of the United States (CES-DR) and the Yesavage Geriatric Depression Scale (GDS). Materials and methods In the first phase of the study we evaluated the presence of significant DS with the 30-item GDS. Those with scores of 11 or more were considered positive and were included in the second phase. In this phase were added a random sample with negative scores. All participants completed the second phase of the revised CES-DR. The 80 percentile was used in this study with a cut-off of 57 points. Results A total of 7449 elderly were included in the first phase. The prevalence of reported significant DS with the GDS was 21.7% (n = 1.616) (IC-95%, 20.4-23.0). The sample for the second phase included 2 923 elderly. The mean age was 70.8 years, 61.7% were women. Twelve percent (95% CI, 9.2-15.3) showed significant DS of major depression, 7.5% (95% CI, 6.3-8.9) was rated as probable, 17.2% (95% CI, 13.022.3) possible, 2.6% (95% CI, 2.2-3.1) sub-threshold depression episode and 60.7% (95% CI, 56.2-65.1) with no significant DS episodes of major depression. Significant frequency of major depression SD is presented using the GDS and CESDR was 6.5% (95% CI, 3.3-12.4). Conclusions The expression of the identified significant SD CES-DR is different from what is reported to the GDS. The CES-DR is more sensitive and specific to identify the presence of depressive symptoms.

Introducción La depresión en el anciano resulta de interés por su relación con el incremento de la demanda de servicios de salud, así como por su baja frecuencia de diagnóstico. Objetivo Determinar la frecuencia de los síntomas depresivos (SD) entre ancianos derechohabientes de la Ciudad de México, mediante la escala revisada de depresión del Centro de Estudios Epidemiológicos de los Estados Unidos (CES-DR) y la Escala de Depresión Geriátrica de Yesavage (GDS). Materiales y métodos En la primera fase del estudio se evaluó la presencia de SD significativos con la GDS de 30 ítems. Aquéllos con puntaje de 11 o más fueron considerados como positivos y se incluyeron en la segunda fase. En esta fase se agregó una muestra aleatoria con puntajes negativos. Todos los participantes en la segunda fase completaron la versión revisada del CES-DR. El percentil 80 se utilizó en este estudio con un punto de corte de 57 puntos. Resultados Un total de 7449 adultos mayores fueron incluidos en la primera fase. La prevalencia de SD significativos reportada con el GDS fue de 21.7% (n=1,616) (IC-95%, 20.4-23.0). La muestra para la segunda fase incluyó 2923 adultos mayores. La media de edad fue de 70.8 años, el 61.7% eran mujeres. El 12.0% (IC-95%, 9.2-15.3) presentó SD significativos de depresión mayor, 7.5% (IC-95%, 6.3-8.9) fue calificado como probable, 17.2% (IC-95%, 13.0-22.3) como posible, 2.6% (IC-95%, 2.2-3.1) con episodio de depresión sub-umbral y 60.7% (IC-95%, 56.265.1) sin SD significativos de episodios de depresión mayor. La frecuencia de SD significativos de depresión mayor que se presentó utilizando el GDS y el CESDR fue de 6.5% (IC-95%, 3.3-12.4). Conclusiones La expresión de SD significativos identificada con el CES-DR es diferente a lo que se reporta con el GDS. La CES-DR permite identificar la presencia de síntomas de depresión de manera más sensible y específica.

OBJECTIVE: To evaluate the impact of the ADEC program (acronym in Spanish) as compared with the typical care provided to disabled elderly affiliated with the Mexican Institute of Social Security (IMSS). MATERIAL AND METHODS: Prospective cohort at three months after discharge from two general hospitals in Mexico City. A total of 130 patients with functional dependency were studied, 70 in the ADEC program and 60 with typical care. Impact was measured using hospital readmissions and quality of life based on the Sickness Impact Profile (SIP). RESULTS: Average age was 74 (61/103) years and 60% were women. The main diagnosis was cerebrovascular disease (30.77%). The quality of life in the psychosocial dimension improved for the ADEC group (from 46.26 (±13.85) to 29.45(±16.48) as compared with 47.03 (±16.47) to 42.36 (±16.35) for those receiving typical care (p<0.05). No differences were found regarding hospital readmissions. (p>0.05). CONCLUSIONS: HC program improved the psychosocial dimension of quality of life.

OBJECTIVE: To determine the psychometric qualities of the CES-DR and GDS scales in the elderly and compare them to clinical psychiatric diagnoses. MATERIAL AND METHODS: The first phase consisted of home interviews for determining the psychometric qualities of the GDS and CES-DR scales. In the second phase, psychiatrists conducted diagnostic interviews. The sample consisted of 534 participants older than 60 years of age insured by the Mexican Institute of Social Security. RESULTS: First phase: Cronbach's alpha for the GDS was 0.87 and 0.86 for CES-DR. The GDS factorial analysis found eight factors that could explain 53.5% of the total variance and nine factors that explained 57.9% in the CES-DR. Second phase: Compared to the psychiatric diagnoses, CES-DR reported a sensitivity of 82% and a specificity of 49.2%; GDS reported 53.8% sensitivity and 78.9% specificity. CONCLUSIONS: CES-DR and GDS scales have high reliability and adequate validity but the CES-DR reports higher sensitivity.

OBJECTIVE: The aim of this study was to evaluate the effect of dental state on the capacity of elderly individuals to carry out their daily activities during the previous six months. MATERIAL AND METHODS: A transversal study was conducted in the Mexican Institute of Social Security (IMSS) with insured elderly persons residing in southwestern Mexico City. Home interviews were conducted to gather sociodemographic data, data on the use of oral health services, problems in carrying out daily activities, and their relationship with the state of dentition over the past six months, utilizing the Oral Impacts on Daily Performance (OIDP) index. Later, three oral health professionals trained in determining the state of dentition according to World Health Organization (WHO) criteria performed a clinical examination on each elderly subject. RESULTS: A total of 540 elderly individuals were studied. The prevalence of elderly persons with problems in carrying out their daily activities was 21.5%. The main problems in daily activities were eating (14.4%), speaking (8.7%), not becoming irritated (5.4%), brushing their teeth(5%), and inability to enjoy contact with people (4.4%). There is a positive OIDP correlation between number of teeth lost and the decayed, missing, filled teeth(DMFT) index (p<0.05) and a negative correlation with the number of functional and filled teeth. CONCLUSIONS: The state of dentition in the elderly has repercussions on the capacity to carry out daily activities, with quality of life most seriously affected with regard to eating and enjoying food, as well as with respect to correct pronunciation.
