RESUMO
BACKGROUND: Research exploring the link between dietary riboflavin intake and cognitive decline in this demographic is limited. Our aim was to examine the association between riboflavin intake levels and cognitive decline. METHODS: The National Health and Nutrition Examination Survey (NHANES) data from 2011 to 2014 were utilized in this cross-sectional analysis. The Consortium to Establish a Registry for Alzheimer's Disease test Word Learning delayed recall trial (DR), Digit Symbol Substitution Test (DSST), Animal Fluency Test(AFT) and Z test were used to evaluate cognitive performance. Multivariate logistic regression, restricted cubic spline and subgroup analysis were performed to evaluate the associations between riboflavin intake and cognitive decline. RESULTS: The study included a total of 2255 patients, with 47.9% being male. The incidence of cognitive decline was 23.8%. After adjusting for all selected covariates, we found that high riboflavin intake was associated with a lower risk of cognitive impairment in adults in the United States. When riboflavin intake was used as a Categorical variable, compared to those with the lowest intake, the odds ratio (OR) of individuals with the highest riboflavin intake for DR test, AFT test, DSST test and Z test were 0.73 (95% CI: 0.53~1), 0.68(95% CI: 0.49-0.96),0.53(95% CI: 0.37-0.77) and 0.56(95% CI: 0.39-0.8). The study also found an L-shaped association between riboflavin intake and cognitive decline, with an inflection point at approximately 2.984 mg/d. CONCLUSIONS: Our cross-sectional study in a nationwide sample of American old adults suggests that dietary riboflavin intake was negative associated with cognitive decline.
RESUMO
PURPOSE: The aim of this study was to describe a population of very old people with heart failure (HF), to analyse the use of cardiovascular drugs over time, and to explore factors influencing cardiovascular drug treatment for this group. METHODS: All participants with information regarding HF diagnosis were selected from the Umeå 85+/Gerontological Regional Database (GERDA). The people in GERDA are all ≥85 years old. Trained investigators performed structured interviews and assessments. Information regarding medications and diagnoses was obtained from the participants and from medical records. Medical diagnoses were reviewed and confirmed by an experienced geriatrician. RESULTS: In this very old population, the prevalence of HF was 29.6% among women and 30.7% among men. Between 2000 and 2017, there was an increase in the use of renin-angiotensin (RAS) inhibitors (odds ratio [OR] 1.107, 95% confidence interval [CI] 1.072-1.144) and beta-blockers (BBs) (OR 1.123, 95% CI 1.086-1.161) among persons with HF, whereas the prevalence of loop diuretics (OR 0.899, 95% CI 0.868-0.931) and digitalis (OR 0.864, 95% CI 0.828-0.901) decreased (p < 0.001 for all drug classes). Higher age was associated with lower use of RAS inhibitors and BBs. CONCLUSION: In this HF population, the use of evidence-based medications for HF increased over time. This may be a sign of better awareness among prescribers regarding the under-prescribing of guidelines-recommended treatment to old people. Higher age associated with a lower prevalence of RAS inhibitors and BBs. This might indicate that further improvement is possible but could also represent a more cautious prescribing among frail very old individuals.

Aging may increase the risk of maxillofacial and dentoalveolar trauma (MDT). This review assessed global trends in scientific publications on MDT in the elderly. Six databases were searched. Studies about MDT in the elderly (≥60 years old) were included in two text mining stages (S1 and S2). In S1, all studies with elderly subjects were included, while in S2 only studies in which the elderly were assessed in a separate set of data or in a subanalysis by age groups were included. In S1, relevant data were mined using VantagePoint™ software. In S2, data were descriptively analyzed. There were 2265 studies at S1 and 110 at S2. The publication dates spanned from 1963 to 2023. In S1, the most cited keywords and terms were aged (n = 1872), male (n = 1839), female (n = 1777), "mandible fracture" (n = 460), "orbit fracture" (n = 362), and "maxilla fracture" (n = 118). Thirty authors published 10 or more articles with visible collaboration networks. There was a progressive increase in publications, especially in Europe (n = 150). In S2, most studies were case reports/case series (n = 62). The primary etiology was accidental falls (n = 84), the most affected region was the middle third of the face (n = 65), and dental trauma was rarely reported (n = 15). Cone Beam computed tomography was the most used diagnostic tool (n = 67). Of the 81 articles that addressed therapy, 52 opted for surgical treatment. Although there has been an increase in the number of articles on MDT over the years, studies with the elderly population as a specific study group are still needed. Accidental falls were the most reported etiology, while the middle third of the face and the mandible were the anatomic region and bone most affected, respectively. The high number of case reports indicates the need for improvement in the available scientific evidence about MDT in the elderly.

The Integrated Care for Old People (ICOPE) guidelines were developed by the World Health Organization. These guidelines address functional abilities in older adults in six intrinsic capacity domains, including cognitive decline, limited mobility, malnutrition, visual impairment, hearing loss, and depressive symptoms with the goal of improving their assessment and management. In this article, aging is interpreted from the perspective of Chinese medicine and guided by the theory of Yin Yang, the five elements, the six ICOPE domains, and the five organs (liver, heart, spleen, lungs, and kidneys). Huang Di Nei Jing's concept of disease prevention is proposed in a manner that corresponds to the three-stage preventive public health strategy for promoting health, delaying the effects of aging, and improving quality of life in older adults.

BACKGROUND: 'Perturbation-based balance training' (PBBT) is a training method that was developed to improve balance reactive responses to unexpected balance loss. This training method is more effective in reducing fall rates than traditional balance training methods. Many PBBTs are performed during standing or treadmill walking which targeted specifically step reactive responses, we however, aimed to develop and build a mechatronic system that can provide unexpected perturbation during elliptical walking the Elliptical Perturbation System (the EPES system), with the aim of improving specifically the trunk and upper limbs balance reactive control. METHODS: This paper describes the development, and building of the EPES system, using a stationary Elliptical Exercise device, which allows training of trunk and upper limbs balance reactive responses in older adults. RESULTS: The EPES system provides 3-dimensional small, controlled, and unpredictable sudden perturbations during stationary elliptical walking. We developed software that can identify a trainee's trunk and arms reactive balance responses using a stereo camera. After identifying an effective trunk and arms reactive balance response, the software controls the EPES system motors to return the system to its horizontal baseline position after the perturbation. The system thus provides closed-loop feedback for a person's counterbalancing trunk and arm responses, helping to implement implicit motor learning for the trainee. The pilot results show that the EPES software can successfully identify balance reactive responses among participants who are exposed to a sudden unexpected perturbation during elliptical walking on the EPES system. CONCLUSIONS: EPES trigger reactive balance responses involving counter-rotation action of body segments and simultaneously evoke arms, and trunk reactive response, thus reactive training effects should be expected.

INTRODUCTION: Low physical activity (PA) is a potential risk factor for dementia and cognitive impairment. However, few studies have focused on very old people (aged ≥80 years), the age group with highest prevalence of dementia. The aim was to investigate if PA associated with subsequent dementia, cognitive function, and gait speed (GS), in very old people. METHODS: A population-based survey was conducted in 1999 and followed-up between 2016 and 2019 in participants ≥80 years. Altogether 541 individuals (56.2% women), 64.9 ± 4.2 years of age at baseline participated. Self-rated baseline PA was categorized into low, medium, or high. Cognitive function was assessed with the Mini-Mental State Examination (MMSE), executive function with the Frontal Assessment Battery (FAB), and GS (in meters/second) was measured over 2.4 m at follow-up. RESULTS: During a mean of 19.0 ± 1.1 years, 175 (32.3%) developed dementia. Low or medium PA compared to high PA did not associate with subsequent dementia, and PA did not associate with future cognitive function (MMSE). PA associated with executive function (FAB) (unstandardized beta [95% confidence interval]) (0.67 [0.07-1.27]), but not after adjustments. PA associated with subsequent GS in the unadjusted model and after adjustment for age, sex, smoking, and education (0.06 [0.02-0.09], and 0.04 [0.01-0.08], respectively), but not after adding adjustment for hypertension, obesity, and glucose intolerance. CONCLUSION: No support was found for the hypothesis that low PA is a potential risk factor for dementia in very high age. However, PA and executive function were associated in unadjusted analyses which indicate that PA may be important for at least one aspect of cognitive function. The association between PA and GS around 2 decades later seems attenuated by cardiometabolic risk factors. Future investigations regarding PA, dementia, and cognitive decline may consider cardiometabolic risk factors such as hypertension, obesity, and glucose intolerance, and include repeated measures of PA over the life course.

BACKGROUND: Femoral neck fracture and lacunar cerebral infarction (LCI) are the most common diseases in the elderly. When LCI patients undergo a series of traumas such as surgery, their postoperative recovery results are often poor. Moreover, few studies have explored the relationship between LCI and femoral neck fracture in the elderly. Therefore, this study will develop a ML (machine learning)-based model to predict LCI before surgery in elderly patients with a femoral neck fracture. METHODS: Professional medical staff retrospectively collected the data of 161 patients with unilateral femoral neck fracture who underwent surgery in the Second Affiliated Hospital of Wenzhou Medical University database from January 1, 2015, to January 1, 2020. Patients were divided into two groups based on LCI (diagnosis based on cranial CT image): the LCI group and the non-LCI group. Preoperative clinical characteristics and preoperative laboratory data were collected for all patients. Features were selected by univariate and multivariate logistic regression analysis, with age, white blood cell (WBC), prealbumin, aspartate aminotransferase (AST), total protein, globulin, serum creatinine (Scr), blood urea nitrogen (Bun)/Scr, lactate dehydrogenase (LDH), serum sodium and fibrinogen as the features of the ML model. Five machine learning algorithms, Logistic regression (LR), Gradient Boosting Machine (GBM), Extreme Gradient Boosting (XGBoost), Random Forest (RF), and Decision tree (DT), were used in combination with preoperative clinical characteristics and laboratory data to establish a predictive model of LCI in patients with a femoral neck fracture. Furthermore, indices like the area under the receiver operating characteristic (AUROC), sensitivity, specificity, and accuracy were calculated to test the models' performance. RESULTS: The AUROC of 5 ML models ranged from 0.76 to 0.95. It turned out that the RF model demonstrated the highest performance in predicting LCI for femoral neck fracture patients before surgery, whose AUROC was 0.95, sensitivity 1.00, specificity 0.81, and accuracy 0.90 in validation sets. Furthermore, the top 4 high-ranking variables in the RF model were prealbumin, fibrinogen, globulin and Scr, in descending order of importance. CONCLUSION: In this study, 5 ML models were developed and validated for patients with femoral neck fracture to predict preoperative LCI. RF model provides an excellent predictive value with an AUROC of 0.95. Clinicians can better conduct multidisciplinary perioperative management for patients with femoral neck fractures through this model and accelerate the postoperative recovery of patients.

BACKGROUND: The Covid-19 pandemic and associated visiting restrictions have challenged communication with others for older people residing in nursing homes. AIM: The aim of this study was to explore residents' experiences of encounters and communication with staff and relatives and friends during the Covid-19 pandemic. DESIGN: An exploratory study with an inductive approach. METHODS: Semi-structured telephone interviews with 16 Swedish nursing home residents were conducted. Data were analyzed using qualitative content analysis; the study reports according to the COREQ checklist. RESULTS: Three main categories emerged: (1) Mixed feelings and experiences of encounters with nursing staff, (2) Adapting to hampered communication and finding strategies to overcome language barriers, and (3) Facing pandemic restrictions and living an adjusted life. Nine subcategories are reported within these categories. Residents mainly reported good encounters with staff and receiving the care they needed, but unhelpful encounters were also reported. To manage communication with staff with limited Swedish language skills, residents developed several strategies. During the visiting ban, residents felt secure but also lonely. Staying connected with the outside world required residents to use the phone and handle other digital aids, such as video calls, but lack of technical skills among staff hindered frequent use of video calls. CONCLUSION: This study highlights how residents can feel safe in extreme situations, but increased competence, including digital literacy and language skills, among staff is required. Care providers should provide relevant information to residents and staff and employ competent staff. Findings indicate that communication plans need to include enabling communication for residents both within and outside nursing homes, taking staff language skills into consideration.

BACKGROUND: The growth of frail older patients with extensive care needs in homecare creates a need for competence development. Improvement programmes are essential to fill this knowledge gap. However, the outcomes of such programmes remain unknown. Therefore, the aim of this study is to describe the outcomes of a competence improvement programme for the systematic observation of frail older patients in homecare. METHODS: This study applied a qualitative mixed-method design. Data were collected in two homecare districts using participant observation, focus group interviews, and individual interviews. RESULTS: The analysis revealed five concepts characterising the outcomes of the competence improvement programme: 1) frequency of vital sign measurements, 2) situational awareness, 3) expectations and coping level, 4) activities for sustained improvement, and 5) organisational issues affecting CIP focus. Substantial differences were revealed across the two homecare districts in how homecare professionals enacted new knowledge and routines resulting from the competence improvement programme. The differences were related to the frequency of vital sign measurements, coping levels, and situational awareness, in which successful outcomes were shaped by implementation issues and contextual setting. This involved whether routines and planned activities were set to follow up the improvement programme, or whether organisational issues such as leadership focus, resources, and workforce stability supported the programme. CONCLUSIONS: This study documents the differences entailed in creating sustainable outcomes of an improvement programme for homecare professionals' competence in recognising and responding to deteriorating frail older patients. Depending on the implementation process and the homecare context, professionals enact the activities of the improvement programme differently.

BACKGROUND AND OBJECTIVE: A small number of national studies have explored the barriers to older people accessing dental care; however, to date none have investigated older people's recommendations for overcoming these barriers. METHODS: Semi-structured interviews were conducted with 40 dentate older people (65 years and over) who resided in New Zealand's Otago region and received home-support. A joint inductive thematic analysis was undertaken, based on the constant comparative method. RESULTS: Recommendations for boosting community-dwelling older people's access to dental care included publicly funding or subsiding the cost of dental care for older people, aligning the pension with the real cost of living, and making the environment at Work and Income less hostile and the emergency dental grant more readily available, making dental clinics more accessible, initiating domiciliary dental care, having mobile dental clinics visit neighbourhoods with high proportions of older people, as well as subsidised transport to the dental clinic. Other suggestions were having GPs, pharmacists and social workers emphasise oral health during appointments, along with dental education campaigns. CONCLUSION: In order to boost the rates of dental care access among older New Zealanders who receive home support, multiple structural changes are necessary, but these should primarily focus on reducing the cost and increasing accessibility.

The increase in the number of older people (elderly and senile) among the population around the world is associated with a significant impact on the increase in the incidence of malignant neoplasms (MN). The federal project «Fight against oncological diseases for 2018-2024¼ has been launched in Russia within the framework of the national project «Healthcare¼. The article presents the results of a study of the general disability (primary and repeated) of the adult population due to MN in the Chechen Republic (2010-2020). The main trends in the dynamics of general disability (age differentiation, severity, level) in the Chechen Republic and in the North Caucasus Federal District as a whole are compared. Older people with disabilities prevail in the structure of both primary and repeated disability due to MN in the Chechen Republic. This corresponds to the indicators for the North Caucasus Federal District and correspond to the data for the Russian Federation as a whole. The level of disability in the Chechen Republic is lower compared to the indicators for the North Caucasus Federal District. The proportion of disabled people with severe group II and group I disabilities is higher in the republic compared to extensive indicators for the district. The formed structure of disability and the identified trends in its dynamics are a scientific and practical basis that is advisable to use when developing an integrated approach to the medical and social rehabilitation of disabled people and the prevention of health disorders due to MN, taking into account the identified features of disability of the population in the territorial subject of the Russian Federation.

Cardiovascular prevention is also particularly successful in old people in terms of preventing major cardiovascular events. The concept of prevention of geriatric diseases can, however, be expanded taking the insights of geroscience into consideration, so that slowing the ageing process per se can be set as a new goal: ageing is the pertinent basis of nearly all chronic diseases in adulthood, a line of argument for which the cardiovascular system can serve as a prototype. Consequently, treating ageing can help prevent the typical chronic diseases in old people, i.e. multimorbidity and frailty. According to the current guidelines of the European Society of Cardiology (ESC, Eur Heart J 42:3227-3337, 2021) and the German Society for Cardiology (DGK, https://leitlinien.dgk.org/files/03_pocket_leitlinien_praevention_aktualisiert.pdf ) cardiovascular prevention incorporates age-stratified and individually adapted measures and treatment targets in the domains lifestyle (physical activity, body weight, nutrition), psychosocial factors, cardiovascular risk factors (smoking, blood lipids, blood pressure, diabetes), antithrombotic treatment and disease-specific interventions. From a biogerontological perspective, in the midterm these measures could be supplemented by measures and medicinal treatment strategies to slow the biological ageing process, e.g. with senolytics and metformin. Initial clinical studies using senolytics have already been reported.

OBJECTIVE: we aimed to investigate the association of smoking cessation with risk of all-cause mortality amongst oldest old people (aged ≥ 80 years). DESIGN: this was a prospective cohort study. SETTING: the Chinese Longitudinal Healthy Longevity Survey, implemented in 23 provinces of China. PARTICIPANTS: a total of 28,643 community-dwelling oldest old people (mean age, 92.9 ± 7.5 years) were included. METHODS: in this community-based cohort study, Cox proportional hazards models were used to examine the association of smoking cessation with risk of all-cause mortality. RESULTS: during 136,585 person-years of follow-up from baseline to 1 September 2014, compared with never smokers, hazard ratios and 95% confidence intervals for all-cause mortality were 1.06 (1.02-1.10) for current smokers, 1.23 (1.09-1.39) for transient quitters (≤1 consecutive years since smoking cessation), 1.22 (1.12-1.32) for recent quitters (2-6 consecutive years since smoking cessation) and 1.11 (1.02-1.22) for long-term quitters (>6 consecutive years since smoking cessation). Cox models with penalised splines revealed an increased risk of all-cause mortality after smoking cessation; the highest mortality risk was observed within 2-4 years after smoking cessation and the risk gradually decreased with duration of smoking cessation. We further conducted subgroup analyses and sensitivity analyses to reduce the impact of reverse causation. CONCLUSIONS: smoking is harmful to health in all populations. Our study findings indicated smoking cessation in late life to be associated with increased risk of all-cause mortality amongst oldest old people who have smoked for a long time.

BACKGROUND: Sepsis is one of the most frequent reasons for acute intensive care unit (ICU) admission of very old patients and mortality rates are high. However, the impact of pre-existing physical and cognitive function on long-term outcome of ICU patients ≥ 80 years old (very old intensive care patients (VIPs)) with sepsis is unclear. OBJECTIVE: To investigate both the short- and long-term mortality of VIPs admitted with sepsis and assess the relation of mortality with pre-existing physical and cognitive function. DESIGN: Prospective cohort study. SETTING: 241 ICUs from 22 European countries in a six-month period between May 2018 and May 2019. SUBJECTS: Acutely admitted ICU patients aged ≥80 years with sequential organ failure assessment (SOFA) score ≥ 2. METHODS: Sepsis was defined according to the sepsis 3.0 criteria. Patients with sepsis as an admission diagnosis were compared with other acutely admitted patients. In addition to patients' characteristics, disease severity, information about comorbidity and polypharmacy and pre-existing physical and cognitive function were collected. RESULTS: Out of 3,596 acutely admitted VIPs with SOFA score ≥ 2, a group of 532 patients with sepsis were compared to other admissions. Predictors for 6-month mortality were age (per 5 years): Hazard ratio (HR, 1.16 (95% confidence interval (CI), 1.09-1.25, P < 0.0001), SOFA (per one-point): HR, 1.16 (95% CI, 1.14-1.17, P < 0.0001) and frailty (CFS > 4): HR, 1.34 (95% CI, 1.18-1.51, P < 0.0001). CONCLUSIONS: There is substantial long-term mortality in VIPs admitted with sepsis. Frailty, age and disease severity were identified as predictors of long-term mortality in VIPs admitted with sepsis.

BACKGROUND: Older people who are non-weight-bearing after a lower limb fracture are at risk of poor outcomes but there are no clinical guidelines for this group of patients. Given the paucity of the research evidence base, we conducted a consensus exercise to ascertain expert opinion about the management of this group. METHODS: A three-round e-Delphi technique was planned to use the online JISC survey tool with a multidisciplinary panel of health professionals. Panellists were invited by email via professional organisations and UK NHS Trusts. The initial statements for this study were prepared by the authors based upon the findings of their scoping review. Consensus required >/= 70% agreement with statements. RESULTS: Only 2 survey rounds were required. Ninety panellists, representing seven clinical disciplines, reached consensus for 24 statements about general issues (osteoporosis detection and management, falls risk reduction and nutrition) and specific non-weight bearing issues (such as the need for activity to be promoted during this period). CONCLUSIONS: These findings can be used in the generation of a clinical guideline for this group of patients.

BACKGROUND: Balance control, and specifically balance reactive responses that contribute to maintaining balance when balance is lost unexpectedly, is impaired in older people. This leads to an increased fall risk and injurious falls. Improving balance reactive responses is one of the goals in fall-prevention training programs. Perturbation training during standing or treadmill walking that specifically challenges the balance reactive responses has shown very promising results; however, only older people who are able to perform treadmill walking can participate in these training regimes. Thus, we aimed to develop, build, and pilot a mechatronic Perturbation Stationary Bicycle Robotic system (i.e., PerStBiRo) that can challenge balance while sitting on a stationary bicycle, with the aim of improving balance proactive and reactive control. METHODS: This paper describes the development, and building of the PerStBiRo using stationary bicycles. In addition, we conducted a pilot randomized control trial (RCT) with 13 older people who were allocated to PerStBiRo training (N = 7) versus a control group, riding stationary bicycles (N = 6). The Postural Sway Test, Berg Balance Test (BBS), and 6-min Walk Test were measured before and after 3 months i.e., 20 training sessions. RESULTS: The PerStBiRo System provides programmed controlled unannounced lateral balance perturbations during stationary bicycling. Its software is able to identify a trainee's proactive and reactive balance responses using the Microsoft Kinect™ system. After a perturbation, when identifying a trainee's trunk and arm reactive balance response, the software controls the motor of the PerStBiRo system to stop the perturbation. The pilot RCT shows that, older people who participated in the PerStBiRo training significantly improved the BBS (54 to 56, p = 0.026) and Postural Sway velocity (20.3 m/s to 18.3 m/s, p = 0.018), while control group subject did not (51.0 vs. 50.5, p = 0.581 and 15 m/s vs. 13.8 m/s, p = 0.893, respectively), 6MWT tended to improve in both groups. CONCLUSIONS: Our participants were able to perform correct balance proactive and reactive responses, indicating that older people are able to learn balance trunk and arm reactive responses during stationary bicycling. The pilot study shows that these improvements in balance proactive and reactive responses are generalized to performance-based measures of balance (BBS and Postural Sway measures).

BACKGROUND: Vestibular rehabilitation (VR), specifically, VR with dynamic computerized posturography (CDP) has proven to be useful to improve balance and reduce the risk of falling in old patients. Its major handicap is probably its cost, which has hindered its generalisation. One solution to reduce this cost is performing VR with mobile posturography systems, which allow assessment of stability at the center of body mass in daily-life conditions. Also, rehabilitation with vibrotactile neurofeedback training could be used in dynamic tasks. OBJECTIVE: To assess whether two different protocols of vestibular rehabilitation (using CDP and the Vertiguard system) show significant differences in the improvement of balance among older persons with imbalance METHODS: A clinical trial comparing VR with CDP exercises and VR with mobile posturography (Vertiguard) exercises, was designed. The participants were people over 65 years, with imbalance. The composite (average balance) in the sensory organization test (SOT) of the CDP was the main outcome measure; it was compared before and 3 weeks after VR, and between both intervention groups. RESULTS: 40 patients were included in the study (19 in the CDP-VR group and 21 in the Vertiguard-VR group). Average balance was significantly improved in both intervention groups (51% pre-VR vs 60% post-VR, p = 0.002, CDP-VR group; 49% pre-VR vs 57% post-VR, p = 0.008, Vertiguard-VR group); no significant differences in this improvement were found comparing both groups (p = 0.580). DISCUSSION AND CONCLUSIONS: VR using mobile posturography is useful to improve stability in old people with instability, showing similar improvement rates to those of VR using CDP.

Improving dementia screening procedures beyond simple assessment of current cognitive performance is timely given the ongoing phenomenon of population aging. A slow or declining gait speed (GS) is a potential early indicator of cognitive decline scarcely investigated in very old people. Here, we investigated the 5-year associations of baseline GS, change in GS, and cognitive function with subsequent dementia development in people aged 85 years and older (n = 296) without dementia at baseline. Declining and a slow baseline GS were associated with higher odds of dementia development after adjusting for confounders (e.g., age, sex, and dependency in activities of daily living) and missing GS values at follow-up. The GS decline was associated with cognitive decline in participants who developed dementia. The results support the potential of GS tests to predict future cognitive decline among community- and nursing home-dwelling very old people.

Lynn Vivier-Foucart testifies here to her dual experience as a volunteer storyteller for the association Âge d'or de France and as a palliative care attendant. It is a question of transmitting and giving, of receiving and restoring that which, through natural empathy with elderly people in residential homes for the dependent elderly, can contribute, if not to awaken memories, at least to give pleasure. And to listen to the person accompanying them.

BACKGROUND: Recurrent falls represent a priority in geriatric research. In this study we evaluated the influence of pain as a risk factor for recurrent falls (two or more in 1 year) in the older (65-79 years) and oldest-old (80 or more years) non-institutionalized population. METHODS: Prospective cohort study. 772 non-institutionalized individuals with ages of 65 years or older (with overrepresentation of people aged 80 years or older [n = 550]) were included through randomized and multistage sampling, stratified according to gender, geographic area and habitat size. Basal evaluation at participant's home including pain evaluation by Face Pain Scale (FPS, range 0-6) and then telephonic contact every 3 months were performed until complete 12 months. Multivariate analysis by logistic regression (recurrent falls as outcome variable) for each age group (older and oldest-old group) were developed considering pain as a quantitative variable (according to FPS score). Models were adjusted for age, gender, balance, muscle strength, depressive symptoms, cognitive decline, number of drugs and number of drugs with risk of falls. RESULTS: 114 (51.35%) and 286 (52%) participants of older and oldest-old group, respectively, reported pain; and recurrent falls occurred in 6.93% (n = 12) of the older group and 12.06% (n = 51) of the oldest-old group. In the older group, pain was associated with recurrent falls, with an associated odds ratio (OR) of 1.47 (95% CI 1.08-2.00; beta 0.3864) for each unit increase in pain intensity (thus, participants with the most severe pain [FPS 6] had OR of 10.16 regarding to participants without pain [FPS 0]). In the oldest-old group, pain was not associated with recurrent falls. CONCLUSIONS: Pain, a potentially modifiable and highly prevalent symptom, is a risk factor for recurrent falls in the older people (65-79 years). However, we have not been able to demonstrate that this relationship is maintained in the oldest-old population (80 or more years).
