Health benefits of multicomponent training programmes in seniors: a systematic review.

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.

[Inappropriate prescription and administration of medications in 10 nursing homes in Alsace, France]. / Prescriptions et administrations inappropriées de médicaments dans dix établissements alsaciens d'hébergement pour personnes âgées dépendantes--France.

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.

[Prescribing inappropriate medication: the new STOPP/START criteria]. / Prescription médicamenteuse inappropriée: les nouveaux critères STOPP/START.

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.

How important is vitamin D in preventing infections?

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.

Six-month outcome of elderly people hospitalized via the emergency department: the SAFES cohort.

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.

[Chronic obstructive pulmonary disease: risk and benefit of testosterone therapy]. / Bronchopneumopathie chronique obstructive: risques et bénéfices d'un traitement de testostérone.

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.

Tracing thymic output in older individuals.

As a result of age-associated thymic atrophy, T cell production declines with age. Some studies suggest that production undergoes an exponential decline starting at birth, while others consider the decline to be in a biphasic manner with a rapid reduction in output occurring before middle age followed by a phase in which output declines at a regular, albeit much slower, rate. Both approaches provide estimations of the time of termination of thymic output, but on the basis of limited amounts of data. We have analysed blood from more than 200 individuals between the ages of 58 and 104 years to determine changes in thymic output using signal-joint T cell receptor excision circles (sjTREC)/T cells as our measure. To reduce any potential geographical or nutritional bias we have obtained samples from five different European countries. Our results reveal that while the absolute number of T cells per microlitre of blood does not change significantly across the age range we tested, the values of sjTREC per microlitre show wide variation and reveal an age-associated decline in thymic output. In addition we show gender differences, with notably higher thymic output in females than males at each decade. More importantly, we noted a significant decline in sjTREC/T cell levels in those more than 90 years of age in both males and females. Our results provide information about the potential end-point for thymic output and suggest that sjTREC analysis may be a biomarker of effective ageing.

[Sarcopenia: a new geriatric hot topic]. / Sarcopénie: nouveau thème d'actualité en gériatrie.

Highly prevalent in the population older than 65 years, and leading to poor outcomes (functional decline and its related consequences), sarcopenia does not benefit yet either of a clear understanding of its patho-physiology. Its origin, its risk factors, its clinical presentation will be detailed. The diagnosis of sarcopenia imposes a clear identification of the risk factors, a specific muscular assessment, a pragmatic clinical approach. The treatment is based on nutritional supplements and/or drugs which to be active need to be associated to physical exercises of moderate intensity. Geriatricians are expecting new therapy to delay the consequences of sarcopenia, e.g. frailty and inability in daily living.

Derivation and validation of a mortality-risk index from a cohort of frail elderly patients hospitalised in medical wards via emergencies: the SAFES study.

To identify predictive factors for 2-year mortality in frail elderly patients after acute hospitalisation, and from these to derive and validate a Mortality Risk Index (MRI). A prospective cohort of elderly patients was set up in nine teaching hospitals. This cohort was randomly split up into a derivation cohort (DC) of 870 subjects and a validation cohort (VC) of 436 subjects. Data obtained from a Comprehensive Geriatric Assessment were used in a Cox model to predict 2-year mortality and to identify risk groups for mortality. A ROC analysis was performed to explore the validity of the MRI. Five factors were identified and weighted using hazard ratios to construct the MRI: age 85 or over (1 point), dependence for the ADL (1 point), delirium (2 points), malnutrition risk (2 points), and co-morbidity level (2 points for medium level, 3 points for high level). Three risk groups were identified according to the MRI. Mortality rates increased significantly across risk groups in both cohorts. In the DC, mortality rates were: 20.8% in the low-risk group, 49.6% in the medium-risk group, and 62.1% in the high-risk group. In the VC, mortality rates were respectively 21.7, 48.5, and 65.4%. The area under the ROC curve for overall score was statistically the same in the DC (0.72) as in the VC (0.71). The proposed MRI appears as a simple and easy-to-use tool developed from relevant geriatric variables. Its accuracy is good and the validation procedure gives a good stability of results.

Predicting early mortality among elderly patients hospitalised in medical wards via emergency department: the SAFES cohort study.

OBJECTIVES: The aim of the study was, by early identification of deleterious prognostic factors that are open to remediation, to be in a position to assign elderly patients to different mortality risk groups to improve management. DESIGN: Prospective multicentre cohort. SETTING: Nine French teaching hospitals. PARTICIPANTS: One thousand three hundred and six (1 306) patients aged 75 and over, hospitalised after having passed through Emergency Department (ED). MEASUREMENTS: Patients were assessed using Comprehensive Geriatric Assessment (CGA) tools. A Cox survival analysis was performed to identify prognostic variables for six-week mortality. Receiver Operating Characteristics analysis was used to study the discriminant power of the model. A mortality risk score is proposed to define three risk groups for six-week mortality. RESULTS: Crude mortality rate after a six week follow-up was 10.6% (n=135). Prognostic factors identified were: malnutrition risk (HR=2.1; 95% CI: 1.1-3.8; p=.02), delirium (HR=1.7; 95% CI: 1.2-2.5; p=.006), and dependency: moderate dependency (HR=4.9; 95% CI: 1.5-16.5; p=.01) or severe dependency (HR=10.3; 95% CI: 3.2-33.1; p < .001). The discriminant power of the model was good: the c-statistic representing the area under the curve was 0.71 (95% IC: 0.67 - 0.75; p < .001). The six-week mortality rate increased significantly (p < .001) across the three risk groups: 1.1% (n=269; 95% CI=0.5-1.7) in the lowest risk group, 11.1% (n=854; 95% CI=9.4-12.9) in the intermediate risk group, and 22.4% (n=125; 95% CI=20.1-24.7) in the highest risk group. CONCLUSIONS: A simple score has been calculated (using only three variables from the CGA) and a practical schedule proposed to characterise patients according to the degree of mortality risk. Each of these three variables (malnutrition risk, delirium, and dependency) identified as independent prognostic factors can lead to a targeted therapeutic option to prevent early mortality.

[Disabled elderly people waiting for institutionalization to a hospital ward: prospective study in the administrative district of Strasbourg (France)]. / Personnes âgées dépendantes en attente d'entrée en EHPAD depuis un service hospitalier: étude prospective sur la communauté urbaine de Strasbourg, France.

OBJECTIVES: Our aim was to estimate the number of non-satisfied instutionalization requests for inpatients and to describe the strategies elaborated to compensate for the waiting time. METHODS: This prospective follow-up study concerning all requests for institution admission for inpatients aged 75 years or older hospitalized in acute care and rehabilitation wards. Descriptive data were gathered throughout the social support process conducted during the hospitalization. A three months follow-up was conducted. RESULTS: Among 5200 hospitalizations, a social support process was initiated for 270 patients aged 75 years and over. Two thirds of the sample were women (n=163). Mean age was 82 years. Fifty-two percent of the subjects met the criteria for iso-resource grades (IRG) 1 to 2 and 90% in IRG 1 to 4. The mean length of hospitalized stay (MLOS) was 56.8+/-10.2 days; the MLOS of unjustified stay of 23.5+/-5.6 (n=222). The average time before the social worker was informed of the patient's situation was 13.6+/-2.0 days; in addition, the time required to establish the administrative documents necessary for initiation of the social support progress was 15.0+/-1.8. The principal reasons for social support were physical dependence (77%), mental dependence (60%), insufficient family support (36%) and/or disease progression (21%). At three months, 104 patients were institutionalized, 128 were still on institution waiting list (in hospital: 48%; at home: 16%) and 38 had died (14%). The estimated annual institutional deficit for disabled elderly people was 512 beds. CONCLUSION: In light of demographical perspectives, an overall re-organization of the geriatric network is absolutely necessary. A simple increase in the capacity to fulfil the institutional beds deficit would be insufficient.

[Serotonin syndrome as a result of escitalopram and cyclosporin combination in an 84-year-old woman]. / Syndrome sérotoninergique consécutif à l'association d'escitalopram et de cyclosporine chez une patiente de 84 ans.

Due to the stimulation of central and peripheral 5-hydroxytryptamine receptors, the serotonin syndrome is a potentially lethal situation. The large variety of its clinical manifestations leads to a difficult diagnosis. We describe the case of a serotonin syndrome induced by the combined escitalopram and cyclosporine administration. An 84-year-old woman was hospitalized with a history of delirium associated with hyperthermia. The diagnosis of serotonin syndrome was suspected with the combination of the clinical features: the absence of infection, the selective serotonin reuptake inhibitor administration, and the absence of other metabolic and cerebral aetiology. After the discontinuation of escitalopram, the patient's condition improved rapidly. This report is a reminder of the clinical and pharmacological features of the serotonin syndrome from a recent literature review.

[Delirium in old age. Difficulties in diagnosis]. / Syndrome confusionnel du sujet âgé: les difficultés d'un diagnostic facile.

Confusion is a frequent psychiatric and behavioural manifestation of diffuse cerebral injury found in elderly patients that are severely ill or stressed. The hyperactive form is often recognised because of the psychomotor agitation. However, the hypoactive form is most frequent and has a worse prognosis. Despite, it is often under-recognised. Among contributing factors, anticholinergic agents and drug interactions are significant. Identification and treatment of the underlying cause of delirium is essential with a focus on non pharmacological approach. Antipsychotic agents are reserved for severe forms and where non pharmacological intervention fracases.

[Herpes zoster and post-herpetic neuralgia in older adults]. / Zona et névralgies postzostériennes de la personne âgée.

Varicella-Zoster virus is responsible for chickenpox and, after reactivation, herpes zoster. Herpes zoster causes a vesicular dermatomal rash, traditionally metameric. Old adults can present severe pain during the acute phase, and late complications, such as post-herpetic neuralgia that can trying and crippling. Initiated within the first 72 hours of the rash, antivirals accelerate rash healing, reducing both rash and acute pain severity but incompletely the onset of other complications. Complementary therapeutic drug is often necessary. However, their application in old, frail, co-morbid and often poly-medicated patients have to be carefully considered as their use may be contraindicated. A specific vaccine is enable to reduce herpes zoster-related morbidity.

Screening for urinary incontinence in acute care for elders unit: comparative performance analysis of Katz's ADL and ICIQ-UI-SF.

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.

Vitamin D Supplementation in Nursing Home Residents: Randomized Single Cholecalciferol Loading Protocol vs. Individualized Loading Dose Regimen.

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.

[Microbial description of bacteriuria in long-term care facilities: a prospective study in the French Teaching Hospital of Strasbourg]. / Description de la flore bactérienne responsable des bactériuries symptomatiques en unité de soins de longue durée: étude prospective au CHRU de Strasbourg.

OBJECTIVE: The authors had for aim to assess, the incidence of symptomatic bacteriuria and the level of antibiotic resistance in bacteria identified in long-term care facilities (LTC). DESIGN: Symptomatic bacteriuria cases were prospectively collected, during 9 months in the two LTC of the Strasbourg French Teaching Hospital (196 beds). RESULTS: One hundred and eleven bacteriuria cases were included. They concerned 67 of the 274 residents (cumulative incidence: 2.07/1,000 patients-day). A gram-negative bacillus was identified in 85% of the symptomatic bacteriuria cases, and Escherichia coli in 40%. Sixty percent of the identified bacterial strain was resistant to amoxicillin (Amx-R) and 42% to the clavulanic acid combination (AmC-R). Third generation cephalosporins (3GC) were effective in 90% of Urinary tract infections (UTIs) and fluoroquinolones in 65% (Fq). Four bacterias with broad beta-lactamase spectrum were identified (0.04%) including 3 Enterobacter aerogenes. No yeast infection was diagnosed. E. coli strains were 65% Amx-R and 50% AmC-R. Concerning the Fq-R strains (15%), 50% were cotrimoxazole resistant (Stx-R) and 70% Amx-R; 3GC remained effective (82%). CONCLUSION: In LTC, multi-drug resistance bacteria are rare and 3GCs seem to be the best first line treatment. Nevertheless, Fq-R is increasing (15 vs 8%), and attention must be paid to the antibiotic therapy used.

[Recommendations for treatment and prevention of herpes zoster and associated pain in aged adults]. / Recommandations pour le traitement et la prévention du zona et des douleurs associées chez la personne âgée.

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.

[Home living conditions in Alsace of the disabled elderly aged 75 years and more]. / Description des conditions de vie de la population âgée de 75 ans ou plus vivant à domicile en Alsace.

OBJECTIVE: Our aim was to describe the living conditions of disabled elderly subjects aged 75 years and more living at home. DESIGN: This study was conducted in 1996-97 in the Alsace region in France and included two parts. First, a sample survey was mailed to 15,600 subjects randomly selected from a pension funds list. This survey provided with a reliable representation of the study population in terms of disabilities using the Colvez classification. In the second part, the most disabled individuals were selected and, among them, 1,259 subjects were visited at home. Their disabilities and living conditions were noted using a predefined set of questions. RESULTS: An estimated 71,000 subjects aged 75 years and more lived at home in the study region. The vast majority were free of significant disability. Help to wash and dress was needed by 6,000 until 1,500 were bedridden or confined to an armchair. Between 4,350 and 5,400 met the criteria for iso-resource grades (IRG) 1 to 3. Disability was associated with age, female gender, cognitive impairment and some social and professional characteristics. Family support was routine in almost every aspect of everyday life including personal hygiene. Professional support was mostly limited to technical interventions. Professional nursing care concerned only the most dependent persons. Nevertheless, needs for help in home and social activities remained high even in the least dependent individuals and were strongly age-dependent. Only 10% of individuals with IRG 1 to 3 complained of inadequate help. More than 80% of the elderly felt comfortable with their living conditions at home and were not thinking of moving from home to an institution for old people. CONCLUSION: The present study confirms the important commitment of family members and their close relationships toward their elderly.
