RESUMEN

BACKGROUND: Urinary incontinence (UI) is a frequent, but neglected geriatric syndrome, particularly in vulnerable older patients. Optimizing screening procedures is necessary. OBJECTIVE: To compare the clinometric performances of the "continence" item of the Katz's ADL scale and the ICIQ-UI-sf for the screening of UI in vulnerable aged patients. METHODS: A prospective study was conducted in the acute care for elders (ACE) unit of an academic centre. Two independent nurses screened all patients with spontaneous urination for UI with Katz's ADL item and ICIQ-UI-sf upon the hospital admission. The diagnosis of UI resulted from an interdisciplinary conciliating meeting for urinary functional disorders (TOFU), gathering geriatricians and neuro-urologists and was considered as reference. RESULTS: 294 consecutive patients (mean age 86.2 ± 6.5 years; 76.5% female) admitted to the ACE unit were screened; 169 were incontinent (57.5%) according to TOFU. The Katz's ADL item identified 106 incontinent patients with 20 false positives; 83 incontinent patients were not identified. If the sensitivity and specificity of the ICIQ-UI-sf were 100.0%, they were, respectively, 50.9 and 84.0% for the Katz's ADL item. Positive and negative predictive values were 100.0% for ICIQ-UI-sf; 81.1 and 55.9% for ADL, respectively. CONCLUSION: This study validates the ICIQ-UI-sf as a simple and effective screening tool for UI in vulnerable and complex hospitalized aged patients. It also demonstrates that the "continence" item of the Katz's ADL scale is not sensitive enough for UI screening in this population.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of a single cholecalciferol loading protocol in nursing home (NH) residents taking no VitD supplementation at regular basis. DESIGN: Randomized single-blind controlled study. SETTING: One NH. PARTICIPANTS: All residents. INTERVENTION: From March 21st to May 19th, 2015, NH residents were randomly assigned to either 4x100'000IU to be taken every 2 weeks (treatment group) or an individualized regimen according to baseline 25(OH)VitD level (control group). MEASUREMENTS: 25(OH)VitD, calcium, phosphorus, parathyroid hormone, alkaline phosphatase, and creatinine serum levels were centrally measured at day 7 after the last dose in both groups, and at baseline in the control group. RESULTS: 111 residents (mean age 85.1±6.7 years) were randomized to the treatment (N=53) or the control group (N=58). No significant difference in terms of demographic characteristics, risk for osteoporosis, and past history of VitD supplementation was measured. At baseline, 37.9%, 25.5% and 5.2% were respectively sub-optimal, insufficient, and deficient for VitD. Whatever the study group, at the 7th day after the last dose of cholecalciferol, 100% of residents reached serum values ≥20ng/mL (p value for non-inferiority <0.001 and p value for superiority p=1.00) and 93.6 vs. 88.2% reached values ≥30ng/mL in the treatment and control group respectively (p value for non-inferiority <0.01 and p value for superiority p=0.48). While mean value was higher in the treatment group (50.2±615.4 vs. 35.8±66.5ng/mL; p<0.0001), none of participants have seen their value >150 ng/mL. Not any biological adverse effects was measured. CONCLUSION: This study confirmed that a single loading protocol is at least as effective and safe as tailored regimen in terms of the ability to rapidly normalize 25(OH)VitD values. The often required dosage of 25(OH)VitD is reasonably not necessary to initiate VitD supplementation protocol in this vulnerable population.

RESUMEN

BACKGROUND: The ageing process is intrinsically associated with decline in physical endurance, muscle strength and gait ability and balance, which all contribute to functional disability. Regular physical training, and more particularly multicomponent training (MCT), has demonstrated many health benefits. OBJECTIVE: To evaluate the evidence of the health benefits of MCT including endurance training, muscle strengthening, balance exercises, and/or stretching (i.e. flexibility training) and/or coordination training in adults aged 65 years or over. METHODS: A comprehensive, systematic database search for manuscripts was performed in CINAHL Plus, Embase, Medline, PubMed Central, ScienceDirect, Scopus, Sport Discus and Web of Science using key words. For potential inclusion, two reviewers independently assessed all intervention studies published in English language from 1 January 2000 to 30 April 2015. RESULTS: Of 2525 articles initially identified, 27 studies were finally included in this systematic review. They were all divided into five categories according to their main outcome measurements (cardio-respiratory fitness, metabolic outcomes, functional and cognitive functions and quality of life, QoL). These studies reported that MCT has a significant beneficial effect on cardio-respiratory fitness and on metabolic outcomes. Substantial improvement in functional and cognitive performance was also measured and a slighter but positive effect on QoL. CONCLUSION: Overall, this review demonstrates a positive effect of MCT with functional benefits and positive health outcomes for seniors. Based on this evidence, clinicians should encourage all adults aged 65 or over to engage in MCT programmes to favour healthy ageing and keeping older members of our society autonomous and independent.

RESUMEN

BACKGROUND: Medication care is a complicated process in nursing homes. The aim of the study was to offer an overview of inappropriate medication prescription and administration practices in nursing homes in Alsace in order to propose improvement actions to remedy the weaknesses identified. METHODS: This study was conducted prospectively in 10 nursing homes under contract with community pharmacies in Alsace. The practices of prescription were examined to determine the prevalence of potentially inappropriate medications, inappropriate and contraindicated medication associations. Crushing and opening practices were also assessed, daily treatment costs were calculated. RESULTS: Two hundred and eighty-four residents were included (age: 87.1 ± 5.6 years). The average number of drugs per resident was 8.1 ± 4.0 (daily treatment cost: 4.19 ± 5.21 €). On average, 1.5 drugs ± 1.4 per prescription were considered as potentially inappropriate (daily treatment cost: 0.49 ± 0.76 €). The contraindication associations concerned 8 % of prescriptions and involved potentially inappropriate drugs in 60 % of cases. Inappropriate associations mainly concerned nervous system drugs. Thirty-three residents were taking more than 2 psychotropic drugs; 23 had more than one benzodiazepine. Regarding drug administration, practices differed from one nursing home to another. Crushing was performed in 8 nursing homes. It concerned 20 residents (7 %) and 69 drugs. In 50 %, the crushing decision was made by nurses without physician or pharmacist supervision. Fifty-seven percent of crushed drugs had a formulation which did not allow crushing (n=39 drugs). The analysis of those items led to the proposal of improvement actions. CONCLUSION: This study pointed out inappropriate medication practices. Tracking tools for inappropriate clinical practices could be operated by physicians, pharmacists and nursing teams through coordinated multidisciplinary approaches.

RESUMEN

Initiated within the first 72 hours of the rash, prescribing antiviral drugs reduces both acute neuralgia (AN) and later complications and especially postherpetic neuralgia (PHN). But their analgesic as well as preventative effect on AN and PHN is modest. Combination with analgesic drugs is more often needed for pain management. However, the pharmacological management of pain, in the context of old patients' frailty, co-morbidities and often polypharmacy, must be carefully considered. Based on analyses of the evidences from the literature, this review presents the therapeutic options we have at one's disposal and proposes a stepwise management for both AN and PHN specifically designed for aged population.

RESUMEN

The growing use of direct oral anticoagulants, in particular among older subjects, raises questions about the limits of the evidence-based medicine. The phase III studies that have validated the efficacy and the safety profile of these molecules (dabigatran, rivaroxaban, apixaban, edoxaban) in their both indications, the venous thromboembolic disease and the non-valvular atrial fibrillation raise concerns in four major fields: the financial support of pharmaceutical companies, the links of interest for many authors with the industry, the study design (exclusively non-inferiority studies), and the poor representativeness of the older subjects included. All these points are discussed, using data of sub-groups studies, post-marketing studies and recent meta-analysis. The lack of data for the very old subjects, with frailty or comorbidities, remains the main concern from these phase III studies.

RESUMEN

OBJECTIVE: To assess prescribing of anticoagulants in atrial fibrillation (AF) in the elderly, both a quantitative point of view (rate of anticoagulation) and qualitative (type of anticoagulation). Determinants of prescribing and non-prescribing were also analysed. METHODS: Prospective survey of practice, based on one clinical case and questionnaire conducted in 60 practitioners (20 cardiologists [C], 20 geriatricians [G] and 20 general practitioners [GP]). RESULTS: In reading the clinical case, 88.3% of physicians would have initiated a treatment; three types of treatments would have been chosen: AVK (68.3%), ODA (20.0%) and platelet antiaggregant (11.7%). Criteria taken into account to initiate anticoagulation varied according to the specialty. Cardiologists considered more the age criteria (C: 95.0%, G: 75.0%, MG: 60.0%; P<0.05), diabetes (C: 90.0%, G: 60.0%, MG: 55.0%; P<0.05), hypertension (C: 85.0%, G: 55.0%, MG: 60.0%; P<0.05) and female gender (C: 80.0%, G: 35.0%, MG: 25.0%; P<0.05). The quality of renal function was however a more secondary criteria (C: 15.0%, G: 5.0%, MG: 0.0%; P<0.05). General practitioners considered most frequently the presence of underlying heart disease (C: 35.0%, G: 5.0%, MG: 45.0%; P<0.05) as well as usual cardiovascular risk factors (overweight, dyslipidaemia; P<0.05). Risk of bleeding, however, was observed by 76.7% of physicians in the clinical situation presented (C: 70.0%, G: 75.0%, MG: 85.0%; P<0.05). CONCLUSION: This survey confirms that the FA remains under anticoagulated in the elderly and the barriers to the prescription of oral anticoagulation are often without rational basis.

RESUMEN

Prescribing anticoagulant therapy when the CHA2DS2-VASc score is ≥ 1 prevents strokes secondary to non-valvular atrial fibrillation (AF). However, it is important to remember that whether the aged population has the highest risk of stroke in case of AF, under anticoagulant therapy this population is also at the highest risk of bleeding. Vitamin K antagonists were for decades the molecules of reference with benefits even after 75 years of age. The direct oral anticoagulants have overcome the biological constraints inherent to monitoring vitamin K antagonists and provide a more stable pharmacological action with a limited number of drug-drug interactions. However, the widespread use of these molecules in the older population remains controversial. In this review article, indications and modalities of administration of anticoagulant therapy in the elderly will be detailed and discussed on the basis of the most recent recommendations proposed in particular by the European Society of Cardiology. Particular attention will be paid to new oral anticoagulant therapies compared with vitamin K antagonists and antiplatelet agents.

RESUMEN

Prescribing inappropriate medication (PIM) is a common public health problem. Mainly due to associated adverse drugs events (ADE), it results in major morbidity and mortality, as well as increased healthcare utilization. For a long time, the systematic review of medications prescribed appeared as a solution for limiting PIM and the ADE associated with such prescriptions. With this aim and since 2008, the list of STOPP-START criteria has appeared as attractive in its design, as well as logical and easy to use. The initial version has just been updated and improved. After having detailed all improvements provided to the 2008 version, we present the result of its adaptation into French language by a group of French-speaking expert from Belgium, Canada, France, and Switzerland.

RESUMEN

BACKGROUND & AIMS: Healthcare-associated infections [HAI] are common in elderly individuals and may be related to both nutritional deficiencies and immunosenescence. Here, we assessed whether overall malnutrition and/or specific nutrient deficiencies were associated with HAI via alterations in immune parameters. METHODS: Prospective observational cohort study in patients aged ≥ 70 years admitted to the geriatric rehabilitation unit of a teaching hospital in France between July 2006 and November 2008. Clinical and laboratory parameters reflecting nutritional status and immune function were collected at baseline. Flow cytometry was used to assess blood lymphocyte subsets including the naive CD4 T-cell count, naive and memory CD8 T-cell counts, effector CD8 T-cell count, and CD4/CD8 ratio. Patients were monitored for HAI for 3 months or until discharge from the geriatric unit or death. RESULTS: Of 252 consecutive in-patients aged ≥ 70 years [mean age, 85 ± 6.2 years], 181 [72%] met French National Authority for Health criteria for malnutrition and 97 [38%] experienced one or more HAI. Patients who subsequently experienced HAI had significantly lower baseline values for energy intake [odds ratio (OR), 0.76; 95% confidence interval (95%CI), 0.59-0.99], serum albumin [OR, 0.43; 95%CI, 0.32-0.58], serum zinc [OR, 0.77; 95%CI, 0.62-0.97], selenium [OR, 0.76; 95%CI, 0.61-0.95], and vitamin C [OR, 0.71; 95%CI, 0.54-0.93]. Associations linking these five variables to HAI were not significantly changed by adjusting for flow cytometry T-cell subset values. CONCLUSION: Our results suggest a direct effect of nutritional parameters on HAI rather than an indirect effect mediated by immune parameters.

RESUMEN

BACKGROUND: The "obesity paradox" is poorly understood in vulnerable older hospitalized populations. OBJECTIVES: To prospectively analyze the impact of body mass index (BMI) and comorbidities on early (6-week), one- and two-year mortality. DESIGN: Prospective multicenter study with a two-year follow-up of old patients participating in the SAFES cohort study. SETTINGS: Nine university hospitals in France. PARTICIPANTS: Patients aged 75 or older hospitalized in medical divisions through the emergency department. MEASUREMENT: Inpatients' characteristics were obtained through a comprehensive geriatric assessment of inpatients, conducted in the first week of hospitalization. All-cause mortalities at 6-week, one- and two-year were determined using bivariable and multivariable Cox proportional hazard model. RESULTS: The SAFES cohort included 1,306 patients, aged 85±6 years, with a majority of women (65%). One- and two-year mortality were inversely associated with BMI ≥30 kg/m2 while early mortality was not, and positively associated with age, burden of comorbidities, walking disorders, level of dependency and presence of a dementia syndrome. Survival rates between patients in low (< 18.0 kg/m2) and intermediate (18-24.9 and 25-29.9 kg/m2) BMI categories were not significant. CONCLUSION: While our findings seem to confirm the reality of the "obesity paradox" in vulnerable older hospitalized population, the exact understanding of underlying mechanisms and even the truthfulness of this paradoxical relationship are still fraught with considerable methodological, epidemiological and metabolic challenges.

RESUMEN

Respiratory rate is one of the key vital signs yet unlike temperature, heart rate or blood pressure, there is no simple and low cost measurement device for medical use. Here we discuss the development of a respiratory sensor based upon clavicular motion and the findings of a pilot study comparing respiratory rate readings derived from clavicular and thoracic motion with an expiratory breath flow reference sensor. Simultaneously sampled data from resting volunteers (n = 8) was analysed to determine the location of individual breaths in the data set and from these, breath periods and frequency were calculated. Clavicular sensor waveforms were found to be more consistent and of greater amplitude than those from the thoracic device, demonstrating good alignment with the reference waveform. On comparing breath by breath periods a close agreement was observed with the reference, with mean clavicular respiratory rate R(2) values of 0.89 (lateral) and 0.98 (longitudinal-axis). This pilot study demonstrates the viability of clavicular respiratory sensing. The sensor is unobtrusive, unaffected by bioelectrical or electrode problems and easier to determine and more consistent than thoracic motion sensing. With relatively basic signal conditioning and processing requirements, it could provide an ideal platform for a low-cost respiratory monitor.

RESUMEN

The level of T-cell receptor excision circles (TREC), which decline with advancing age in normal individuals, has recently gained interest as a reference marker for studies on premature or early immunosenescence under particular health conditions. In order to facilitate translational studies at population and clinical levels, essential for the understanding of how changes in TREC levels are associated with responsiveness of the immune system, we have developed and optimized a real-time polymerase chain reaction (qPCR) assay which quantifies the TREC ratio from dried blood spot (DBS) samples. The present study considers a fully automated procedure to purify DNA and amplify sequences of interests by means of qPCR from DBS samples collected in healthy adults. Both TREC:PBMC (peripheral blood mononuclear cell) and TREC:T-cell ratios were compared for intra- and inter individual reproducibility. Furthermore, the impact of the length of storage on the quality of the DNA generated was also analyzed. In conclusion we describe a fully automated procedure for extracting DNA and qPCR set up, which offers a high-precision, robust qPCR assay for the quantification of both TREC:T-cell ratio and TREC:PBMC from DBS samples.

RESUMEN

Interaction with the immune system is one of the most recently established nonclassic effects of vitamin D (VitD). For many years, this was considered to be limited to granulomatous diseases in which synthesis of active 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) or calcitriol is known to be increased. However, recent reports have supported a role for 1,25(OH)2D3 in promoting normal function of the innate and adaptive immune systems. Crucially, these effects seem to be mediated not only by the endocrine function of circulating calcitriol but also via paracrine (i.e., refers to effects to adjacent or nearby cells) and/or intracrine activity (i.e., refers to a hormone acting inside a cell) of 1,25(OH)2D3 from its precursor 25(OH)D3, the main circulating metabolite of VitD. The ability of this vitamin to influence human immune responsiveness seems to be highly dependent on the 25(OH)D3 status of individuals and may lead to aberrant response to infection or even to autoimmunity in those who are lacking VitD. The potential health significance of this has been underlined by increasing awareness of impaired status in populations across the globe. This review will examine the current understanding of how VitD status may modulate the responsiveness of the human immune system. Furthermore, we discuss how it may play a role in host resistance to common pathogens and how effective is its supplementation for treatment or prevention of infectious diseases in humans.

RESUMEN

Muscular wasting is frequently encountered in COPD patients and is related to a decrease in exercise tolerance, a higher morbidity and mortality. One of the potential causes isa low serum testosterone, which is frequent in COPD. Various studies have explored the effect of testosterone administration alone or as part of combined pulmonary rehabilitation and nutrition protocols. Testosterone had a positive impact on muscle mass and force, and to a lesser extent on physical endurance and respiratory parameters. Future studies should better define appropriate dosage and treatment duration. In the meantime, testosterone should be administered to COPD patients with overt hypogonadism, or in multidisciplinary specialized programmes.

RESUMEN

BACKGROUND: The objective of the study was to identify factors predictive of 6-month institutionalization or mortality in frail elderly patients after acute hospitalization. METHODS: A prospective cohort of elderly subjects 75 years and older was set up in nine French teaching hospitals. Data obtained from a comprehensive geriatric assessment were used in a Cox model to predict 6-month institutionalization or mortality. Institutionalization was defined as incident admission either to a nursing home or other long-term care facility during the follow-up period. RESULTS: Crude institutionalization and death rates after 6 months of follow-up were 18% and 24%, respectively. Independent predictors of institutionalization were: living alone (HR=1.83; 95% CI=1.27-2.62) or a higher number of children (HR=0.86; 95% CI=0.78-0.96), balance problems (HR=1.72; 95% CI=1.19-2.47), malnutrition or risk thereof (HR=1.93; 95% CI=1.24-3.01), and dementia syndrome (HR=1.88; 95% CI=1.32-2.67). Factors found to be independently related to 6-month mortality were exclusively medical factors: malnutrition or risk thereof (HR=1.92; 95% CI=1.17-3.16), delirium (HR=1.80; 95% CI=1.24-2.62), and a high level of comorbidity (HR=1.62; 95% CI=1.09-2.40). Institutionalization (HR=1.92; 95% CI=1.37-2.71) and unplanned readmission (HR=4.47; 95% CI=3.16-2.71) within the follow-up period were also found as independent predictors. CONCLUSION: The main factors predictive of 6-month outcome identified in this study are modifiable by global and multidisciplinary interventions. Their early identification and management would make it possible to modify frail elderly subjects' prognosis favorably.

RESUMEN

OBJECTIVES: To evaluate the predictive ability of four clinical frailty indexes as regards one-year rapid cognitive decline (RCD - defined as the loss of at least 3 points on the MMSE score), and one-year institutional admission (IA) and mortality respectively; and to measure their agreement for identifying groups at risk of these severe outcomes. DESIGN: One-year follow-up and multicentre study of old patients participating in the SAFEs cohort study. SETTING: Nine university hospitals in France. PARTICIPANTS: 1,306 patients aged 75 or older (mean age 85±6 years; 65% female) hospitalized in medical divisions through an Emergency department. MEASUREMENTS: Four frailty indexes (Winograd; Rockwood; Donini; and Schoevaerdts) reflecting the multidimensionality of the frailty concept, using an ordinal scoring system able to discriminate different grades of frailty, and constructed based on the accumulation of identified deficits after comprehensive geriatric assessment conducted during the first week of hospital stay, were used to categorize participants into three different grades of frailty: G1 - not frail; G2 - moderately frail; and G3 - severely frail. Comparisons between groups were performed using Fisher's exact test. Agreement between indexes was evaluated using Cohen's Kappa coefficient. RESULTS: All patients were classified as frail by at least one of the four indexes. The Winograd and Rockwood indexes mainly classified subjects as G2 (85% and 96%), and the Donini and Schoevaerdts indexes mainly as G3 (71% and 67%). Among the SAFEs cohort population, 250, 1047 and 1,306 subjects were eligible for analyses of predictability for RCD, 1-year IA and 1-year mortality respectively. At 1 year, 84 subjects (34%) experienced RCD, 377 (36%) were admitted into an institutional setting, and 445 (34%) had died. With the Rockwood index, all subjects who experienced RCD were classified in G2; and in G2 and G3 when the Donini and Schoevaerdts indexes were used. No significant difference was found between frailty grade and RCD, whereas frailty grade was significantly associated with an increased risk of IA and death, whatever the frailty index considered. Agreement between the different indexes of frailty was poor with Kappa coefficients ranging from -0.02 to 0.15. CONCLUSION: These findings confirm the poor clinimetric properties of these current indexes to measure frailty, underlining the fact that further work is needed to develop a better and more widely-accepted definition of frailty and therefore a better understanding of its pathophysiology.

RESUMEN

Because of their central role orchestrating the immune response, the decrease in repertoire number and diversity of naïve T-cells is a significant feature of immnosenescence. Reflecting the effective naive T-cell pool, quantifying the sj-TREC ratio (number of signal joint T-cell receptor excision circles/10(5) T-cells) in blood samples suffers however from constraints. The most limiting one is the absolute requirement of the flow cytometry analysis of peripheral blood samples for the T-cell numeration. In order to make this ratio more accessible for clinical and epidemiological studies addressing how changes in responsiveness of the immune system lead to an increased susceptibility to various diseases and poorer response to vaccination, we have developed a rapid and simple method for the quantification of the sj-TREC ratio in whole blood and in dried blood spot (DBS) samples. This novel method is a QPCR analysis using fluorescently labelled sequence-specific probes both for quantifying sj-TREC and T-cell count and therefore eliminating the absolute necessity of the flow cytometer analysis. In this pilot study, we have compared the sj-TREC ratio we obtained with this novel method in whole blood and in DBS samples of 10 healthy volunteers with those obtained with the technique of reference and found that they are comparable.

RESUMEN

OBJECTIVES: The aim of the study was to identify factors related to institutionalisation within one-year follow up of subjects aged 75 or over, hospitalised via the emergency department (ED). DESIGN: Prospective multicentre cohort. SETTING: Nine French university teaching hospitals. PARTICIPANTS: One thousand and forty seven (1 047) non institutionalised subjects aged 75 or over, hospitalised via ED. A sub-group analysis was performed on the 894 subjects with a caregiver. MEASUREMENTS: Patients were assessed using Comprehensive Geriatric Assessment (CGA) tools. Cox survival analysis was performed to identify predictors of institutionalisation at one year. RESULTS: Within one year after hospital admission, 210 (20.1%) subjects were institutionalised. For the overall study population, age >85 years (HR 1.6; 95%CI 1.1-2.1; p=0.005), inability to use the toilet (HR 1.6; 95%CI 1.1-2.4; p=0.007), balance disorders (HR 1.6; 95%CI 1.1-2.1; p=0.005) and presence of dementia syndrome (HR 1.9; 95%CI 1.4-2.6; p<0.001) proved to be independent predictors of institutionalisation; while a greater number of children was inversely linked to institutionalisation (HR 0.8; 95%CI 0.7-0.9; p<0.001). Bathing was of borderline significance (p=.09). For subjects with a caregiver, initial caregiver burden was significantly linked to institutionalisation within one year, in addition to the predictors observed in the overall study population. CONCLUSIONS: CGA performed at the beginning of hospitalisation in acute medical wards is useful to predict institutionalisation. Most of the predictors identified can lead to targeted therapeutic options with a view to preventing or delaying institution admission.
