Effect of including a dietary supplement of raisins, a food rich in polyphenols, on cognitive function in healthy older adults; a study protocol for a randomized clinical trial.

BACKGROUND: Polyphenols have been shown to be effective against many chronic diseases, including neurodegenerative diseases. Specifically, the consumption of raisins, being a food rich in polyphenols, has been attributed with neuroprotective benefits. Therefore, our main objective is to evaluate the effect of including 50 g of raisins in the diet daily for 6 months, on the improvement of cognitive performance, cardiovascular risk factors and markers of inflammation in a population of older adults without cognitive impairment. METHODS: Design and intervention: This study will be a randomized controlled clinical trial of two parallel groups. Each subject included in the study will be randomly assigned to one of two study groups: control group (no supplement), intervention group (50 g of raisins daily during 6 months). STUDY POPULATION: The participants will be selected by consecutive sampling in the Primary Care consultations of urban health centers in Salamanca and Zamora (Spain), taking into account the selection criteria. STUDY VARIABLES: Two visits will be made, baseline and at 6 months. Cognitive performance will be evaluated (Mini-Mental State Examination test, Rey Auditory Verbal Learning Test, verbal fluency and montreal cognitive assessment (Moca)). It will also be analyzed the level of physical activity, quality of life, activities of daily living, energy and nutritional composition of the diet, body composition, blood pressure, heart rate, markers of inflammation and other laboratory tests of clinical relevance (glycaemia, total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides). In addition, sociodemographic data, personal and family history, medication use and alcohol and tobacco consumption will be collected. DISCUSSION: In this project, it is intended to contribute to minimize the problems derived from cognitive deterioration in older people.

Oldest old hip fracture patients: centenarians as the lowest complexity patients.

BACKGROUND: Hip fracture leads to an increase in mortality and deterioration in the quality of life. The increase in life expectancy results in an increase in the number of oldest old patients. AIMS: To analyze the characteristics of centenarian hip fracture patients and compare them with younger hip fracture patients. METHODS: Retrospective study, including 176 patients (48 centenarians, 65 nonagenarians and 63 octogenarians) undergoing surgery after hip from 2009 to 2018 and followed for 1-year survival. Qualitative variables were compared by Chi-square test and quantitative variables, by Kruskal-Wallis test. Survival analysis was performed by Kaplan-Meier test and statistical differences were assessed by log-rank test. p value < 0.05 was considered statistically significant. RESULTS: Centenarians showed the lowest Charlson index (p = 0.001), cognitive impairment (p < 0.001), and daily drug intake (p = 0.034). The in-hospital, 30-day and 1-year mortality rates did not show statistical significant differences. The 1-year survival analysis showed that patients died in order of age (p = 0.045). No differences were found regarding readmissions. DISCUSSION: Hip fracture incidence in centenarians is increasing. Our study states the lowest complexity for centenarians. Hip fracture mortality rates have been linked to patients' age. In-hospital mortality rate has been reduced, and for the 30-day and 1-year mortality rates, we noted that mortality follows a pattern clearly related to age. CONCLUSIONS: Centenarians showed the lowest comorbidity and complexity. Readmissions before 1 year, mortality rates at discharge, 30-day and 1-year follow-up were not significantly different, but 1-year survival analysis showed that patients are dying as they are ageing.

Geriatric scores can predict long-term survival rate after hip fracture surgery.

BACKGROUND: The management of hip fractures is nowadays mainly performed in Orthogeriatric Units, one of whose fundamental tools is the application of geriatric scores. The purpose of this study is to establish the potential usefulness of Barthel Index, Katz Index, Lawton-Brody Index and Physical Red Cross Scale geriatric scores as predictors of survival rate and readmission rate in older patients after hip fracture surgery. METHODS: We designed a prospective single-center observational study, including 207 older adults over age 65 who underwent hip fracture surgery in the first half of 2014 and followed up to September 2018. Cumulative survival and readmission rates were analyzed by Kaplan-Meier; group comparison, by Log-Rank and hazard ratio, by Cox regression. RESULTS: We found statistical differences (p < 0.001) for cumulative survival rate by every geriatric score analyzed (BI HR = 0.98 [0.97,0.99]; KI HR = 1.24 [1.13-1.37]; LBI HR = 1.25 [1.16, 1.36]; PCRS HR = 1.67 [1.37,2.04]). Furthermore, we could determinate an inflection point for survival estimation by Barthel Index (BI 0-55/60-100*, p < 0.001, HR = 2.37 [1.59,3.53]), Katz Index (KI A-B*/C-G, p < 0.001, HR = 2.66 [1.80, 3.93], and Lawton-Brody Index (LBI 0-3/4-8*, p < 0.001, HR = 3.40 [2.09,5.25]). We reveal a correlation of the Charlson Index (p = 0.002) and Katz Index (p = 0.041) with number of readmissions for the study period. CONCLUSIONS: The geriatric scores analyzed are related to the cumulative survival rate after hip fracture surgery for more than 4 years, independently of other clinical and demographic factors. Katz Index in combination with Charlson Index could also be a potential predictor of the number of readmissions after surgery for hip fracture patients.

Lower estimated glomerular filtration rate at admission is associated with a worse outcome in older patients with hip fracture who undergo surgical treatment.

BACKGROUND: We assessed the relationship of estimated glomerular filtration rate values at hospital admission on the outcome of surgically treated older adults who had suffered a hip fracture. METHODS: Prospective study that included patients > 65 years of age, surgically treated for primary hip fracture, with no pathologic or high-energy trauma aetiology admitted to a tertiary teaching hospital between 2018 and 2019. We stratified patients based on their estimated glomerular filtration rate at admission and examined its association to demographic and clinical variables, including 90-day post-discharge mortality. RESULTS: The study included 942 hip fracture patients. Lowered estimated glomerular filtration rate was significantly associated to a worsening of the functional status, higher incidence of medical postoperative complications, higher postoperative renal dysfunction, and greater number of blood transfusions. Mortality displayed a staircase pattern, increasing with decreasing estimated glomerular filtration rate. Patients with estimated glomerular filtration rate <60 had significantly higher mortality at 90 days after discharge. In-hospital mortality rate was 10.7% in hip fracture patients with chronic kidney disease who experienced a significant variation in the estimated glomerular filtration rate (>5 mL/min/1.73m2) on admission in comparison to baseline values. CONCLUSION: Older adult patients treated for hip fracture with lower glomerular filtration rate values have poorer functional status and worse prognosis. A significant clinical variation of estimated glomerular filtration rate upon hospital admission for hip fracture may be associated with increased in-hospital mortality of chronic kidney disease patients.

Specialized Care Resources for Diagnosis and Management of Patients Who Have Suffered Falls: Results of a National Survey in Geriatric Units.

INTRODUCTION: Clinical guidelines recommend comprehensive multifactorial assessment and intervention to prevent falls and fractures in older populations. METHODS: A descriptive study was conducted by the Falls Study Group of the Spanish Geriatric Medicine Society (SEMEG) to outline which types of healthcare-specific resources were assigned for fall assessment in Spanish geriatric departments. A self-reported seven-item questionnaire was delivered from February 2019 to February 2020. Where geriatric medicine departments were not available, we tried to contact geriatricians working in those areas. RESULTS: Information was obtained regarding 91 participant centers from 15 autonomous communities, 35.1% being from Catalonia and 20.8% from Madrid. A total of 21.6% reported a multidisciplinary falls unit, half of them in geriatric day hospitals. Half of them reported fall assessment as part of a general geriatric assessment in general geriatric outpatient clinics (49.5%) and, in 74.7% of cases, the assessment was based on functional tests. A total of 18.7% reported the use of biomechanical tools, such as posturography, gait-rides or accelerometers, for gait and balance analysis, and 5.5% used dual X-ray absorptiometry. A total of 34% reported research activity focused on falls or related areas. Regarding intervention strategies, 59% reported in-hospital exercise programs focused on gait and balance improvement and 79% were aware of community programs or the pathways to refer patients to these resources. CONCLUSIONS: This study provides a necessary starting point for a future deep analysis. Although this study was carried out in Spain, it highlights the need to improve public health in the field of fall prevention, as well as the need, when implementing public health measures, to verify that these measures are implemented homogeneously throughout the territory. Therefore, although this analysis was at the local level, it could be useful for other countries to reproduce the model.

Functional Status Geriatric Scores: Single-Handed Tools for 30-Day Mortality Risk After Hip Fracture.

BACKGROUND: The 30-day mortality rate after hip fracture surgery has been considered as an indirect indicator of the quality of care. This work aims to appraise the Barthel Index, Katz Index, Lawton-Brody Index, and Physical Red Cross Scale registered in the Comprehensive Geriatric Assessment at admission on the of 30-day death probability after hip fracture surgery. METHODS: Prospective study including 899 hip fracture patients over 65. Bed-ridden, non-surgically treated patients, and high energy trauma or tumoral etiology fractures were excluded. Variables distribution were assessed by χ2, U-Mann Whitney and we performed binary logistic regression and equal tailed Jeffreys 95% CI for risk assessment. P<0.05 was considered statistically significant. RESULTS: We noted a 30-day mortality rate of 5.9%. We related Barthel Index (OR=0.986 [0.975-0.996], p=0.010), Katz Index (OR=1.254 [1.089-1.444], p=0.002), Lawton-Brody Index (OR=0.885 [0.788-0.992], p=0.037), and Physical Red Cross Scale (OR=1.483 [1.094-2.011], p=0.011) with the 30-day mortality of patients after hip fracture surgery. We also validated the Barthel Index inflection point (0-55) (ORBI(0-55)=2.428 [1.379-4.275], p=0.002) and Katz Index inflection point (A-B) (ORKI(A-B)=0.493 [0.273-0.891], p=0.019) for the assessment of the highest risked patients. CONCLUSION: The geriatric functional status scores would be useful multifunctional and standalone tools in the assessment of hip fracture patients as singly predictors of 30-day mortality.

30-day mortality after hip fracture surgery: Influence of postoperative factors.

PURPOSE: The 30-day mortality rate after hip fracture surgery has been considered as an indirect indicator of the quality of care. The aim of this work is to analyse preoperative and postoperative factors potentially related to early 30-day mortality in patients over 65 undergoing hip fracture surgery. METHODS: Prospective cohort study including all consecutive primary hip fracture patients over 65 admitted to Trauma and Orthopaedics department from January 1, 2018 to December 31, 2019. Bed-ridden, non- surgically treated patients, and high energy trauma or tumoral aetiology fractures were excluded. A total of 943 patients were eligible (attrition rate: 2.1%). Follow-up included 30-days after discharge. We noted the 30-day mortality after hip fracture surgery, analysing 130 potentially related variables including biodemographic, fracture-related, preoperative, and postoperative clinical factors. Qualitative variables were assessed by χ2, and quantitative variables by non-parametric tests. Odds ratio determined by binary logistic regression. We selected preventable candidate variables for multivariate risk assessment by logistic regression. RESULTS: A total of 923 patients were enrolled (mean age 86.22±6.8, 72.9% women). The 30-day mortality rate was 6.0%. We noted significant increased mortality on men (OR = 2.381[1.371-4.136], p = 0.002), ageing patients (ORyear = 1.073[1.025-1.122], p = 0.002), and longer time to surgery (ORday = 1.183[1.039-1146], p<0.001), on other 20 preoperative clinical variables, like lymphopenia (lymphocyte count <103/µl, OR = 1.842[1.063-3.191], p = 0.029), hypoalbuminemia (≤3.5g/dl, OR = 2.474[1.316-4.643], p = 0.005), and oral anticoagulant intake (OR = 2.499[1.415-4.415], p = 0.002), and on 25 postoperative clinical variables, like arrhythmia (OR = 13.937[6.263-31.017], p<0.001), respiratory insufficiency (OR = 7.002[3.947-12.419], p<0.001), hyperkalaemia (OR = 10.378[3.909-27.555], p<0.001), nutritional supply requirement (OR = 3.576[1.894-6.752], p = 0.021), or early arthroplasty dislocation (OR = 6.557[1.206-35.640], p = 0.029). We developed a predictive model for early mortality after hip fracture surgery based on postoperative factors with 96.0% sensitivity and 60.7% specificity (AUC = 0.863). CONCLUSION: We revealed that not only preoperative, but also postoperative factors have a great impact after hip fracture surgery. The influence of post-operative factors on 30-day mortality has a logical basis, albeit so far they have not been identified or quantified before. Our results provide an advantageous picture of the 30-day mortality after hip fracture surgery.

Effect of pharmacological treatment prior to admission on the outcome of older hip fracture patients.

PURPOSE: We aim to relate the pharmacological treatment at admission of hip fracture patients with their prognosis. METHODS: We designed a prospective study including 436 hip fracture patients. We classified all the pharmacological treatment prior to admission of each patient into 25 groups according to their active agent and indications. We followed-up patients for one year for survival, emergency department visits (EDV), and in-hospital re-admissions (RAD). Differential analysis was performed by chi-square test, U-Mann Whitney test, and logistic regression. In all cases, p ≤ 0.05 was considered statistically significant. RESULTS: At 30-day follow-up, 14.9% patients noted EDV, 9.2% RAD, and 3.2% dead. Patients taking beta-blockers (p = 0.046), loop diuretics (p = 0.018) or antiparkinsonian (p = 0.009) showed an increased 30-day EDV; patients taking benzodiazepines (p = 0.014), loop diuretics (p = 0.009) or antiparkinsonian (p = 0.009), an increased 30-day RAD. At one-year follow-up, 50.7% patients noted EDV, 30.7% RAD, and 22.7% dead. Patients taking oral antidiabetics (p = 0.006) noted a greater one-year EDV; patients taking major opioids (p = 0.001), benzodiazepines (p = 0.016), cardiac agents (p = 0.046), loop diuretics (p = 0.042), beta-blockers (p = 0.018), oral anticoagulants (p = 0.013) or gastric prophylaxis (p = 0.020), greater RAD; patients taking cardiac agents (p = 0.024), loop diuretics (p = 0.006) or oral anticoagulants (p = 0.015), increased 1-year mortality rate. CONCLUSIONS: The pharmacological treatment noted at admission for hip fracture patients is related to the outcome, in a dose-independent way. The pharmacological treatment could be an additional parameter that could help us to improve the decision-making process and the resource assignation of hip fracture patients. A proper medication review upon admission because of a hip fracture is warranted.

[An opportunity to identify and prevent frailty through falls intervention.] / Oportunidad para la detección y manejo precoz de la fragilidad a través del abordaje de las caídas.

Falls are one of the classic giant geriatric syndromes with a multifactorial etiopathogenesis and closely related to frailty, being this relationship bidirectional. The Consensus Document on the Prevention of Frailty and Falls approved by the Interterritorial Council of the National Health System in 2014 provides recommendations for the screening of frailty and falls in all older adults in order to develop a management plan in high risk older adults so to prevent disability. This review describes the intrinsic relationship between frailty and falls, falls assessment and screening instruments to use and detect frailty and finally gives evidence-based recommendations to reduce falls impact.

Las caídas son uno de los grandes síndromes geriátricos, con una etiopatogenia multifactorial y con una estrecha relación con la fragilidad, siendo esta relación bidireccional. El Documento de Consenso sobre Prevención de Fragilidad y Caídas aprobado por el Consejo Interterritorial del Sistema Nacional de Salud en 2014, propone un cribado universal de fragilidad y riesgo de caídas, con el objetivo de intervenir en aquellos ancianos de alto riesgo y por tanto prevenir discapacidad. Esta revisión evalúa la relación intrínseca entre caídas y fragilidad, describe las herramientas de valoración del paciente que presenta caídas, incidiendo en aquellos aspectos que detectan fragilidad y finalmente propone intervenciones que han demostrado reducir su impacto.

Time to Surgery Reduction in Hip Fracture Patients on an Integrated Orthogeriatric Unit: A Comparative Study of Three Healthcare Models.

OBJECTIVE: To investigate the clinical efficacy of three different healthcare models (Traditional Model, Geriatric Consultant Model, and Orthogeriatric Unit Model) consecutively applied to a single academic center (University Hospital of Salamanca, Spain) for older hip fracture patients. METHODS: We performed a retrospective study, including 2741 hip fracture patients older than 64 years, admitted between 1 January 2003 and 31 December 2014 to the University Hospital of Salamanca. Patients were divided into three groups according to the healthcare model applied. There were 983 patients on the Traditional Model, 945 patients on the Geriatric Consultant Model, and 813 patients on the Orthogeriatric Unit Model. We recorded age and gender of patients, functional status at admission (Barthel Index, Katz Index, and Physical Red Cross Scale), type of fracture, and intervention, and we analyzed the length of stay, time to surgery, post-surgical stay, and in-hospital mortality according to the healthcare model applied. RESULTS: Hip fractures are much more frequent in women, and an increase in the average age of patients was observed along with the study (P < 0.001). The most common type of fracture in the three models studied was an extracapsular fracture, for which the most common surgical procedure used was osteosynthesis. On the functional status of patients, there were no differences on the ambulatory ability previous to fracture, measured by the Physical Red Cross Scale, and the percentage of patients with a slight dependence determined by the Barthel Index (>60) was similar in both groups, but considering the Katz Index, the percentage of patients with a high degree of independence (A-B) was significantly higher for the group of patients treated on the Orthogeriatric Unit Model period (56%, P = 0.009). The Orthogeriatric Unit Model registered the greatest percentage of patients undergoing surgery (96.1%, P < 0.001) and the greatest number of early surgical procedures (<24 h) (24.8%, P < 0.001). The orthogeriatric unit model showed the shortest duration of stay (9 days median), decreasing by one day in respect of each of the other models studied (P < 0.001). Time to surgery was also significantly reduced with the Orthogeriatric Unit Model (median of 3 days, P < 0.001). With regard to in-hospital follow-up, there was a reduction in in-hospital mortality during the study period. We observed differences among the three healthcare models, but without statistical significance. CONCLUSIONS: The healthcare model based on an Orthogeriatric Unit seems to be the most efficient, because it reaches a reduction in time to surgery, with an increased number of patients surgically treated on in the first 24 h, and the greatest frequency of surgically-treated patients.

[Evaluation of postural control systems in elderly patients with repeated falls]. / Valoración de los sistemas de control postural en ancianos con caídas de repetición.

AIMS: a) to describe postural control disorders in elderly patients with recurrent falls; b) to analyze the influence of sensory deficits on centre of gravity control mechanisms; and c) to assess the functional consequences of balance disorders and falls in this group of patients. MATERIAL AND METHODS: patients aged more than 65 years old referred to a falls unit with two or more falls in the previous 6 months were included in this study. The protocol included posturographic studies with a Neurocom Balance Master. To evaluate motor control, Rhythmic Weight Shift (RWS test) was performed. To assess sensorial control, Modified Clinical Test of Sensory Interaction on Balance (MCT test) was used. Other tests performed were the Sit to Stand (SS test), Walk across (WA test) and Step up over (SO test). RESULTS: a total of 109 patients (85.3% women) were studied. Mean age was 78.01 years (SD: 5.38). Disorders in one or more afferent sensorial systems were found in 51.7% of the patients (27.5% visual deficiencies, 17.6% vestibular alterations, and 6.6% somatosensorial deficits). Two afferent systems were compromised in 25.3%, and all three were compromised in 11.1% of the patients. No significant differences were found in directional control (RWS) when compared with the number of altered systems. CONCLUSIONS: posturographic studies provide sensitive information on static and dynamic centre of gravity control systems, eventual sensory deficits, and patients' ability to carry out basic activities of daily living. In our sample, the most frequent deficit was visual impairment. This information is essential to establish a correct management programme.

[Orthogeriatrics: The First multicentre regional register of hip fractures in Castilla y León (Spain)]. / Ortogeriatría: primer registro multicéntrico autonómico de fracturas de cadera en Castilla y León (España).

OBJECTIVE: The objective of this study is to describe the characteristics of the patients with hip fracture admitted to the Public Hospitals of Castilla y León during three monthly periods (November 2014, and October and November 2015). MATERIAL AND METHOD: The Castilla y León orthogeriatrics work group created a common register to collect data on hip fractures. The study included patients 75 years-old and over hospitalised with hip fractures in the 13 public hospitals in the community during November 2014, and October and November 2015. A multicentre, prospective, and observational study was conducted, in which clinical, functional, and social variables, as well as in-hospital mortality, were collected. RESULTS: The analysis included data from a total of 776 patients with a mean age of 86 (±6) years. The surgical delay was 4±2.8 days, and the mean hospital stay was 10±4.7 days. The anaesthesia risk was ASA 3±0.6. Around two-thirds (66.5%) of the patients had medical complications while in hospital, and 55.5% required a transfusion. In-hospital mortality was 4.6%. The mean pre-surgical stay was related to the overall stay: P<.001. CONCLUSIONS: Hip fracture registers are an essential tool for evaluating the process and for improving the treatment quality of these patients. This is the first multicentre register of hip fracture in the elderly created in a Spanish region, and could be a good precedent reference for a future national register.

[Orthogeriatric activity in public hospitals of Castilla y León: description and review of the literature]. / Actividad ortogeriátrica en los hospitales públicos de Castilla y León: descripción y revisión de la literatura.

The benefits of the collaboration between orthopaedics and geriatrics in the management and care of elderly patients admitted with hip fracture have been widely demonstrated. A questionnaire was sent to all hospital geriatricians of Castilla y León in order to determine the characteristics this collaboration between orthopaedics and geriatrics in the public hospitals of Castilla y León. They were asked about the type of collaboration with orthopaedics in the care of the elderly patient admitted with hip fracture and details of the treatment of the complications. Most of the hospitals maintain a high level of orthogeriatric collaboration with geriatricians, and the geriatrician attends to most of the medical complications of these patients. The average hospital stay is 10 days, with a surgical delay of 3 days. Management of the most frequent clinical problems in hospitals of Castilla y León are detailed in this article, comparing them with the latest articles and current recommendations from clinical practice guides.

[Falls in nursing homes and institutions: update by the Osteoporosis, Falls and Fractures Working Group of the Spanish Society of Geriatrics and Gerontology (GCOF-SEGG)]. / El fenómeno de las caídas en residencias e instituciones: revisión del Grupo de Trabajo de Osteoporosis, Caídas y Fracturas de la Sociedad Española de Geriatría y Gerontología (GCOF-SEGG).

The Workshop on Osteoporosis, Falls and Fractures (GCOF) of The Spanish Geriatrics and Gerontology Society (SEGG) formed a committee in order to review the state of the art on the detection, risk factors and assessment tools for falls, and intervention protocols when falls occurs in nursing homes, long-term hospitals or medium-stay units. The different patient profiles are described in order to make a comprehensive approach to this heterogeneous topic and population, offering a risk classification and specific advice according to these categories.
