Abstract Background Resilience refers to the process in which people function well despite adversity. Persistent severe pain may be considered an adversity in people with lower limb osteoarthritis (LLOA). The objectives of this study are: (1) to identify what proportion of older adults with LLOA and persistent severe pain show good functioning; and (2) to explore predictors of resilience. Methods Data from the European Project on OSteoArthritis (EPOSA) were used involving standardized data from six European population-based cohort studies. LLOA is defined as clinical knee and/or hip osteoarthritis. Persistent severe pain is defined as the highest tertile of the pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index both at baseline and follow-up. Resilience is defined as good physical, mental or social functioning at follow-up despite having LLOA with persistent severe pain. Results In total, 95 (14.9%) out of 638 individuals with LLOA had persistent severe pain. Among these, 10 (11.0%), 54 (57.4%) and 49 (53.8%) had good physical, mental and social functioning, respectively. Only 4 individuals (4.5%) were resilient in all three domains of functioning. Younger age, male sex, higher education, higher mastery, smoking and alcohol use, higher physical activity levels, absence of chronic diseases, and more contacts with friends predicted resilience in one or more domains of functioning. Conclusions Few people with LLOA and persistent severe pain showed good physical functioning and about half showed good mental or social functioning. Predictors of resilience differed between domains, and might provide new insights for treatment.

Abstract Background The Australian/Canadian hand Osteoarthritis Index (AUSCAN) and the Western Ontario and McMaster Universities knee and hip Osteoarthritis Index (WOMAC) are the most commonly used clinical tools to manage and monitor osteoarthritis (OA). Few studies have as yet reported longitudinal changes in the AUSCAN index regarding the hand. While there are published data regarding WOMAC assessments of the hip and the knee, the two sites have always evaluated separately. The current study therefore sought to determine the minimal clinically important difference (MCID) in decline in the AUSCAN hand and WOMAC hip/knee physical function scores over 1 year using anchor-based and distribution-based methods. Methods The study analysed data collected by the European Project on Osteoarthritis, a prospective observational study investigating six adult cohorts with and without OA by evaluating changes in the AUSCAN and WOMAC physical function scores at baseline and 12–18 months later. Pain and stiffness scores, the performance-based grip strength and walking speed and health-related quality of life measures were used as the study’s anchors. Receiver operating characteristic curves and distribution-based methods were used to estimate the MCID in the AUSCAN and WOMAC physical function scores; only the data of those participants who possessed paired (baseline and follow up-measures) AUSCAN and WOMAC scores were included in the analysis. Results Out of the 1866 participants who were evaluated, 1842 had paired AUSCAN scores and 1845 had paired WOMAC scores. The changes in the AUSCAN physical function score correlated significantly with those in the AUSCAN pain score (r = 0.31). Anchor- and distribution-based approaches converged identifying 4 as the MCID for decline in the AUSCAN hand physical function. Changes in the WOMAC hip/knee physical function score were significantly correlated with changes in both the WOMAC pain score (r = 0.47) and the WOMAC stiffness score (r = 0.35). The different approaches converged identifying two as the MCID for decline in the WOMAC hip/knee physical function. Conclusions The most reliable MCID estimates of decline over 1 year in the AUSCAN hand and WOMAC hip/knee physical function scores were 4 and 2 points, respectively.

Resumen: Objetivo: Identificar a la población mayor de 70 años atendida en Atención Primaria, susceptible de participar en un programa de ejercicio físico para prevenir fragilidad. Analizar la concordancia entre 2 criterios para seleccionar la población beneficiaria del programa. Diseño: Estudio transversal de base poblacional. Emplazamiento: Atención Primaria. Participantes: Mayores de 70 años no frágiles residentes del Barrio Peñagrande (distrito Fuencarral, Madrid) pertenecientes a la cohorte de Peñagrande localizables en 2015 y que aceptaron participar (n = 307). Mediciones principales: La variable principal del estudio es la necesidad de prescripción de ejercicio en Atención Primaria en personas mayores de 70 años; se identificó a través de 2 definiciones diferentes: personas prefrágiles (1 o 2 de los 5 criterios de Fried) y personas independientes con desempeño físico limitado, definida por los criterios del documento de consenso sobre prevención de fragilidad y caídas en la persona mayor (mayor de 70 años independiente y con puntuación total del SPPB < 10). Resultados: El 63,84% de los participantes (n = 196) necesitan prescripción del ejercicio por ser prefrágiles y/o por cumplir los criterios definidos en el documento de consenso. En 82 casos cumplían los 2 criterios (prefragilidad y desempeño físico disminuido), 80 eran prefrágiles con desempeño físico normal y 34 eran robustos con desempeño físico limitado. La concordancia entre ambos criterios es débil (índice kappa 0,27). Conclusión: Casi 2 tercios de los mayores presentan algún tipo de limitación funcional. Los criterios del documento de consenso para prevenir la fragilidad detectan a la mitad de los individuos prefrágiles de la comunidad.

Analyze the concordance among 2 criteria to select the beneficiary population of the program. Design: Population-based cross-sectional study. Settings: Primary Care. Participants: Elderly over 70 years old, living in the Peñagrande neighborhood (Fuencarral district of Madrid) from the Peñagrande cohort, who accepted to participate in 2015 (n = 332). Main measurements: The main variable of the study is the need for exercise prescription in people over 70 years old at the Primary Care setting. It was identified through 2 different definitions: Prefrail (1-2 of 5 Fried criteria) and Independent individuals with physical performance limited, defined by Consensus on frailty and falls prevention among the elderly (independent and with a total SPPB score

Abstract Background This study examines the association of both pain severity and within-person pain variability with physical activity (PA) in older adults with osteoarthritis (OA). Methods Data from the European Project on OSteoArthritis were used. At baseline, clinical classification criteria of the American College of Rheumatology were used to diagnose OA in older adults (65–85 years). At baseline and 12–18 months follow-up, frequency and duration of participation in the activities walking, cycling, gardening, light and heavy household tasks, and sports activities were assessed with the Longitudinal Aging Study Amsterdam Physical Activity Questionnaire. Physical activity was calculated in kcal/day, based on frequency, duration, body weight and the metabolic equivalent of each activity performed. At baseline and 12–18 months follow-up, pain severity was assessed using the pain subscales of the Western Ontario and McMaster Universities OA Index and the Australian/Canadian Hand OA Index. Within-person pain variability was assessed using two-week pain calendars that were completed at baseline, 6 months follow-up and 12–18 months follow-up. Results Of all 669 participants, 70.0% were women. Sex-stratified multiple linear regression analyses showed that greater pain severity at baseline was cross-sectionally associated with less PA in women (Ratio = 0.95, 95% CI = 0.90–0.99), but not in men (Ratio = 0.99, 95% CI = 0.85–1.15). The longitudinal analyses showed a statistically significant inverse association between pain severity at baseline and PA at follow-up in women (Ratio = 0.94, 95% CI = 0.89–0.99), but not in men (Ratio = 1.00, 95% CI = 0.87–1.11). Greater pain variability over 12–18 months was associated with more PA at follow-up in men (Ratio = 1.18, 95% CI = 1.01–1.38), but not in women (Ratio = 0.94, 95% CI = 0.86–1.03). Conclusions Greater pain severity and less pain variability are associated with less PA in older adults with OA. These associations are different for men and women. The observed sex differences in the various associations should be studied in more detail and need replication in future research.

The endophytic fungal biodiversity of unique plants like Peperomia argyreia (Miq.) É. Morren (Piperaceae) has antimicrobial properties and can be employed for infection treatment. Fungal isolates were obtained from appropriately treated plant tissues cultured in solid media, characterized by morphology, and identified by molecular biology using ITS and NL primers. The antimicrobial properties of fungal extracts were analyzed by combining microdilution and bioautographic assays complemented with metabolic profiling by automated thin-layer chromatography and 1H NMR techniques. Thirty-one filamentous fungi were isolated and characterized by ITS and/or D1/D2 region amplification of rDNA, identified as Thermothielavioides, Trichoderma, Cyphellophora, Cladosporium, Arcopilus, Plectosphaerella; Chaetomium, Sporothrix, Alboefibula, and Penicillium. Thermothielavioides spp. inhibited Staphylococcus aureus ATCC 25923; moreover, Penicillium westlingii P4 showed inhibitory activity on Ascochyta rabiei AR2. The bioactivity-guided fractionation of the EtOAc extract (MIC = 62.5 μg/mL) of P. westlingii P4 allowed the purification of citrinin as the main inhibitory compound (MIC = 62.5 μg/mL). Peperomia argyreia harbors a rich and diverse endophytic community able to produce bioactive molecules. Citrinin, with a minor influence of volatile compounds biosynthesized by P. westlingii P4, was responsible for the inhibition of A. rabiei AR2.

ABSTRACTThe endophytic fungal community associated with leaves of Ficus carica L. (Moraceae) from Argentina was investigated. Fifteen fungal isolates were isolated and identified by molecular methods into the genera Alternaria, Cladosporium, Curvularia, Diaporthe, Epicoccum, Myrothecium, Neofusicoccum, Nigrospora, Preussia and Ustilago. Cladosporium cladosporioides and Curvularia lunata were the most frequently isolated species. The fungal metabolic profiles were obtained by automated TLC and NMR and analysed by PC Analysis. Antifungal and antibacterial activity was assessed by bioautographic assays. In addition, the biotransforming ability of the fungal isolates was tested on F. carica extracts. Five isolates (33.3%) exhibited inhibitory activity against at least one of the microorganisms tested. Most of the fungal endophytes were able to metabolise the flavonoid rutin 1, and the coumarin psoralen 3 present in F. carica extracts. Further investigations of the psoralen biotransforming ability performed by the selected endophyte Alternaria alternata F8 showed the accumulation of the 6,7-furan-hydrocoumaric acid derivative 4 as the main biotransformation product. Our results corroborate that F. carica can live symbiotically with rich and diverse endophytic communities adding insights about their ecological interactions.

El envejecimiento de la población española se traduce en un aumento de las prestaciones sanitarias requeridas por la población mayor, por ello conocer la frecuencia de la utilización de los servicios sanitarios de este grupo de edad y analizar sus factores determinantes es de especial interés. El objetivo fue analizar la utilización de servicios sanitarios de la población mayor residente en dos barrios urbanos del norte de Madrid. Métodos: Estudio transversal de base poblacional. Se estudió una co - horte de 1.327 individuos igual o mayor a 65 años, estratificada por edad y sexo. Se definieron 9 indicadores de utilización durante el mes anterio o durante el último año. Para cada indicador se calcularon las frecuencias y la asociación con el resto de variables mediante análisis multivariante. Resultados: la distribución de los indicadores expresada como proporción de la población usuaria fue: consultas médico/mes 64,8% (IC95%:62,3-67,4); consultas enfermería/mes 44,6% (IC95%:41,2-47,2); domicilios médico/mes 3,1% (IC95%:2,2-4,1); domicilios enfermería/mes 3%(IC95%:2,1-3,9); hospitalización/año 16,4% (IC95%:14,4-18,4); con - sultas reumatólogo/traumatólogo/año 25,1% (IC95%:22,7-27,4); consul - tas fisioterapeuta/año 12,9% (IC95%:11,1-14,7); consultas podólogo/año 30,6% (IC95%:28,1-33,1) y polimedicados (≥5 fármacos) 55,7% (IC95%: 53-58,4). La comorbilidad fue la variable que mejor predijo la utilización de servicios sanitarios oscilando entre OR 4.10 (IC95%:3.07-5,49) y OR 1,39 (IC95%: 0.97-1.99) para estar polimedicado y visitar al fisioterapeuta res - pectivamente. Enfermedades cardiovasculares (OR 1,34; IC95%:1.03-1,76) y diabetes (OR 1,46; IC95%:1,05-2,02) se asociaron de forma independiente a mayor utilización del médico de familia. La dependencia fue el principal determinante de atención domiciliaria para el médico (OR 3,38; IC95%: 1,38-8,28) y para enfermería (OR 9.71; IC 95%: 4.19-22.48). Trastornos del ánimo se asociaron a mayor polimedicación (OR 2.06; IC95%: 1,48-2.86) y visitas al médico de familia (OR 1,52; IC 95%:1,13-2.04). Conclusiones: La comorbilidad fue la variable que mejor predijo la utilización de servicios sanitarios. Las enfermedades cardiovasculares y la diabetes se asocian de forma independiente a mayor utilización de servicios. Los trastornos del ánimo se asocian a mayor polimedicación y más visitas al médico de familia.

Objetivo: Comprobar el diagnóstico asociado al tratamiento específico para demencia en la historia clínica electrónica de atención primaria (HCE-AP) y analizar los factores asociados a la calidad del registro Método: Estudio descriptivo de los pacientes con anticolinesterásicos o memantina registrados en la Base para Investigación Farmacoepidemiológica en atención primaria (BIFAP) 2011: 24.575 pacientes entre 2002 y 2011. Los diagnósticos asociados a la primera prescripción de estos fármacos se agruparon en 5 categorías: «demencia», «alteraciones de memoria», «enfermedades relacionadas con demencia», «procesos intercurrentes» y «códigos de conveniencia». Se calculó la prevalencia de cada categoría por edad y sexo en cada año de estudio (IC 95%) y se analizaron asociaciones y tendencia 2002-2011, utilizando diferencias de proporciones para muestras independientes y regresión logística binaria. Resultados: El 56,5% (IC 95%: 55,8-57,1) de los pacientes tenían asociado código «demencia» a la primera prescripción. Se registró mejor en mujeres (OR: 1,09 [IC 95%: 1,03-1,15]) y al aumentar el tiempo transcurrido (OR: 1,07 [IC 95%: 1,06-1,08] por cada año de seguimiento). Los «códigos de conveniencia» (16,3% [IC 95%: 15,8-16,7]) se utilizaron más en mujeres y ≥ 80 años; las «alteraciones de memoria» (12,4% [IC 95%: 12,0-12,8]), «enfermedades relacionadas» (4,6% [IC 95%: 4,4-4,8]) y «procesos intercurrentes» (10,3% [IC 95%: 9,9-10,6]) más en hombres y

Objective: To estimate the prevalence and incidence of self-reported diabetes and to study its association with medium- and long-term mortality from all causes in persons ≥65 years. Design: A population-based cohort study begun in 1993. Setting: “Envejecer en Leganés” cohort (Madrid). Participants: A random sample of persons ≥65 years (n = 1277 in the 1993 baseline sample). Methods: Participants were classified as having diabetes if they so reported and had consulted a physician for this reason within the last year. Diabetes history was categorized in

Objetivo: Conocer el consumo de medicamentos entre los mayores de un área de Oporto, determinar la prevalencia de la prescripción de medicamentos potencialmente inapropiados y analizar su asociación con la polimedicación y otros factores. Diseño: Estudio observacional transversal de base poblacional. Emplazamiento: Unidade de Saúde Familiar Rainha D. Amélia, Centro histórico de Oporto (Portugal). Participantes: Muestra de 747 personas representativa de la población de 65 años y más del área de referencia. Mediciones principales: Identificación de todos los medicamentos prescritos utilizando los registros electrónicos disponibles. Se definió polimedicación como el tratamiento simultáneo con 5 o más medicamentos, y medicación potencialmente inapropiada (MPI) como el uso de medicamentos considerados inadecuados según los criterios de Beers 2012. Se recogieron datos sociodemográficos, de diagnóstico y de utilización de servicios. Se utilizó la regresión logística para analizar la asociación de las distintas covariables con el uso de MPI. Resultados: El 89,2% (IC 95%: 87,6-92,0) de la población de estudio tenían prescrito, al menos, un medicamento. El 59,2% (IC 95%: 55,7-62,7) estaban polimedicados. El 37,0% (IC 95%: 33,5-40,5) consumían MPI. La prescripción de MPI se asocia a mayor edad (OR = 1,02 [IC 95%: 1,00-1,05]), polimedicación (OR = 4,45 [IC 95%: 3,12-6,36]), depresión/ansiedad (OR = 2,18 [IC 95%: 1,36-3,51]) y artrosis (OR = 1,64 [IC 95%: 1,11-2,42]). Conclusiones: La prescripción de fármacos, polimedicación y uso de MPI son muy elevados en la población portuguesa estudiada. La polimedicación es el factor más importante asociado al consumo de MPI. La prescripción de ansiolíticos, antidepresivos o antiinflamatorios debe hacerse con mucho cuidado ante el riesgo de los MPI.
