  • Measurement of lean body mass using bioelectrical impedance analysis: a
           consideration of the pros and cons
    • Authors: Giuseppe Sergi; Marina De Rui; Brendon Stubbs; Nicola Veronese; Enzo Manzato
      Pages: 591 - 597
      Abstract: Abstract The assessment of body composition has important applications in the evaluation of nutritional status and estimating potential health risks. Bioelectrical impedance analysis (BIA) is a valid method for the assessment of body composition. BIA is an alternative to more invasive and expensive methods like dual-energy X-ray absorptiometry, computerized tomography, and magnetic resonance imaging. Bioelectrical impedance analysis is an easy-to-use and low-cost method for the estimation of fat-free mass (FFM) in physiological and pathological conditions. The reliability of BIA measurements is influenced by various factors related to the instrument itself, including electrodes, operator, subject, and environment. BIA assumptions beyond its use for body composition are the human body is empirically composed of cylinders, FFM contains virtually all the water and conducting electrolytes in the body, and its hydration is constant. FFM can be predicted by BIA through equations developed using reference methods. Several BIA prediction equations exist for the estimation of FFM, skeletal muscle mass (SMM), or appendicular SMM. The BIA prediction models differ according to the characteristics of the sample in which they have been derived and validated in addition to the parameters included in the multiple regression analysis. In choosing BIA equations, it is important to consider the characteristics of the sample in which it has been developed and validated, since, for example, age- and ethnicity-related differences could sensitively affect BIA estimates.

  • Adiponectin: possible link between metabolic stress and oxidative stress
           in the elderly
    • Authors: Daniela Gradinaru; Denisa Margina; Claudia Borsa; Cristina Ionescu; Mihaela Ilie; Marieta Costache; Anca Dinischiotu; Gabriel-Ioan Prada
      Pages: 621 - 629
      Abstract: Objective The aim of this study was to evaluate the relationships between the serum levels of adiponectin and systemic oxidative stress exerted on lipids, proteins, as well as endothelial function and cardiovascular diseases (CVD) risk markers, in elderly subjects with metabolic syndrome (MS). Methods The serum advanced glycation and oxidation protein products, low-density lipoprotein susceptibility to oxidation (oxLDL), nitric oxide metabolic pathway products (NOx), serum lipid peroxidation, as well as total antioxidant/oxidative capacity (TAC/TOC), were analyzed in elderly subjects with MS (n = 44), compared to aged-matched control (n = 39). Results We pointed out significantly lower levels of adiponectin in elderly MS subjects concomitantly with significantly higher levels of oxidative stress and CVD risk markers. Significant positive correlations were found between serum adiponectin levels and HDL-cholesterol (p < 0.05) and the total cholesterol/LDL-cholesterol ratio (p < 0.01). Additionally, adiponectin levels were significantly inversely associated with insulin resistance index (HOMA-IR, r = −0.348; p < 0.05) and serum lipid peroxidation (r = −0.337; p < 0.05), and significantly positively with the antioxidant capacity (TAC, r = 0.339; p < 0.05). Conversely, adiponectin levels were significantly negatively (r = −0.310; p < 0.05) associated with serum uric acid concentration. Conclusions The major protective role of adiponectin versus stress related to an impaired glucose and lipid metabolism suggests that adiponectin plays a critical role in adiposity-related metabolic stress and redox homeostasis.

  • Utilization of long-term care after decompressive hemicraniectomy for
           severe stroke among older patients
    • Authors: Corey R. Fehnel; Yoojin Lee; Linda C. Wendell; Bradford B. Thompson; N. Stevenson Potter; Vincent Mor
      Pages: 631 - 638
      Abstract: Background While clinical trial data support decompressive hemicraniectomy (DHC) as improving survival among patients with severe ischemic stroke, quality of life outcomes among older persons remain controversial. Aims To aid decision-making and understand practice variation, we measured long-term outcomes and patterns of regional variation for a nationwide cohort of ischemic stroke patients after DHC. Methods Medicare fee-for-service ischemic stroke cases over age 65 during the year 2008 were used to create a cohort followed for 2 years (2009–2010) after stroke and DHC procedure. Rates of mortality, acute hospital readmission, and long-term care (LTC) utilization were calculated. Multiple logistic regression was used to identify individual predictors of institutional LTC. Regional variation in DHC was calculated through aggregation and merging with the state-level data. Results Among 397,503 acute ischemic stroke patients, 130 (0.03 %) underwent DHC. Mean age was 72 years, and 75 % were between the ages of 65 and 74. Mortality was highest (38 %) within the first 30 days. At 2 years, 59 % of the original cohort had died. The 30-day rate of acute hospital readmission was 25 %. Among survivors, 75 % returned home 1 year after index stroke admission. States with higher per capita health expenditures were associated with wider variation in utilization of DHC. Conclusions There is a high rate of mortality among older stroke patients undergoing DHC. Although most survivors of DHC are not permanently institutionalized, there is wide variation in utilization of DHC across the USA.

  • Surgical treatment of pelvic ring fractures in the elderly now and then: a
           pelvic registry study
    • Authors: Mika F. Rollmann; Steven C. Herath; Joerg H. Holstein; Tim Pohlemann; Michael D. Menger; Tina Histing
      Pages: 639 - 646
      Abstract: Background With the demographic change, the treatment of elderly patients has become a major issue for health systems worldwide. Aims The aim of this study was to analyze the change in the rate of surgical treatment of pelvic ring fractures in patients with an age of ≥60 years over a 22-year period depending on fracture type, age and sex. Methods Data of 5665 patients with an age of ≥60 years, who were treated for pelvic ring fractures from 1991 to 2013 in one of 31 hospitals participating in the German Pelvic Trauma Registry, were included. The registry is divided into four time periods: t 1 = 1991–1993, t 2 = 1997–2000, t 3 = 2001–2008 and t 4 = 2009–2013. Data had been collected prospectively and was analyzed retrospectively, stratified for age and sex of the patients as well as type of fracture and mode of therapy (surgical vs. conservative). Results There was a significant increase (p < 0.05) in the overall rate of surgical treatment. Nonetheless, during all time periods patients with an age of >70 years were significantly less frequently surgically treated compared to 60- to 70-year-olds. Regardless of the fracture type, the rate of surgical treatment was significantly higher (p < 0.05) in male compared to female patients during t 1. While this difference persisted for type A and type B fractures, the frequency of surgical treatment of type C fractures approximated in males and females. Conclusions The present data indicate that the rate of surgical treatment of pelvic ring fractures in elderly patients has significantly increased over the 22-year period. Nonetheless, older patients (>70 years) as well as female patients are still less frequently surgically treated.

  • The impaired subjective perception of verticality independent of
           peripheral vestibular function in dizzy elderly with orthostatic
    • Authors: Mitsuhiro Aoki
      Pages: 647 - 653
      Abstract: Background The elderly often complain of faintness, lightheadedness, dizziness, and unsteadiness, which may be associated with the orthostatic hypotension (OH), but most of them are subclinical. The pathogenic mechanism of subjective symptoms in the elderly with OH is controversial. Aims The aim of this study was to assess the involvement of the irregularity of the vertical perception in the dizzy elderly with OH. Methods This study consisted of 403 patients seeking treatment for dizziness in our hospital. The neurotological examinations include the subjective visual vertical (SVV) test and the bithermal caloric test. The self-perceived handicapping effects imposed by dizziness were assessed by the dizziness handicap inventory (DHI). The variability (standard deviation) and the average deviation of eight trials (four trials in each direction) were calculated. In addition, they underwent the orthostatic Schellong test for the diagnosis of the OH. They were separated into three groups, including patients aged ≥65 years, patients aged 50–64 years, and patients aged <50 years. Results The variability of the SVV in the patients aged ≥65 years with OH was significantly larger than that in the patients aged ≥65 years without OH. There was no significant difference in the average deviation of the SVV, the canal paresis % by the bithermal caloric test, and the DHI score among groups. Conclusions The result suggests that the elderly patients with OH have subclinical impairment in the perception of the verticality independent of the peripheral vestibular function.

  • Delirium assessment in hospitalized elderly patients: Italian translation
           and validation of the nursing delirium screening scale
    • Authors: Valentina Spedale; Stefania Di Mauro; Giulia Del Giorno; Monica Barilaro; Candida E. Villa; Jean D. Gaudreau; Davide Ausili
      Pages: 675 - 683
      Abstract: Background Delirium has a high incidence pathology associated with negative outcomes. Although highly preventable, half the cases are not recognized. One major cause of delirium misdiagnosis is the absence of a versatile instrument to measure it. Aims Our objective was to translate the nursing delirium screening scale (Nu-DESC) and evaluate its performance in Italian settings. Methods This was a methodological study conducted in two sequential phases. The first was the Italian translation of Nu-DESC through a translation and back-translation process. The second aimed to test the inter-rater reliability, the sensibility and specificity of the instrument on a convenience sample of 101 hospitalized elderly people admitted to relevant wards of the San Gerardo Hospital in Monza. To evaluate the inter-rater reliability, two examiners tested Nu-DESC on 20 patients concurrently without comparison. To measure the sensibility and specificity of Nu-DESC, the confusion assessment method was used as a gold standard measure. Results The inter-rater reliability (Cohen Kappa) was 0.87—an excellent agreement between examiners. The study of the ROC curve showed an AUC value of 0.9461 suggesting high test accuracy. Using 3 as a cut-off value, Nu-DESC showed 100 % sensibility and 76 % specificity. Discussion and conclusion Further research is needed to test Nu-DESC on a larger sample. However, based on our results, Nu-DESC can be used in research and clinical practice in Italian settings because of its very good and similar performances to previous validation studies. The value of 3 appears to be the optimal cut-off in the Italian context.

  • Do we need orthogeriatrics in Poland' Changes in the age structure and
           location of hip fractures
    • Authors: Robert Wilk; Michał Skrzypek; Małgorzata Kowalska; Damian Kusz; Bogdan Koczy; Piotr Zagórski; Wojciech Pluskiewicz
      Pages: 737 - 743
      Abstract: Background Patients with hip fractures present a great challenge for surgeons due to multimorbidity, polypharmacy as well as difficulty in communicating. These could be attributed to a recent trend in the aging patient population (80 years and older) as compared to the past. The aim of this study is to analyze age structure and location in male and female patients’ population with hip fracture over 50. Materials and methods Hospital records between 2005 and 2014 with ICD-10 codes S72,0, S72,1 and S72,2 were included in the analysis. All fractures occurred in citizen aged 50 years and over living in the district of Tarnowskie Góry and the city of Piekary Śląskie in Poland. Results Within the study period, 1258 hip fractures were registered. The mean age of the patients was higher every year, starting from 77.27 ± 9.52 in 2005 to 80.80 ± 9.65 years in 2014 (p < 0.01). The average age also increased in both gender groups from 73.85 ± 8.30 to 77.89 ± 9.52 years in male and from 78.14 ± 9.66 to 81.98 ± 9.49 years in female, respectively. The median age value was changed from 78.00 to 83.00 years in the total population. We noted a significant increase in female with trochanteric fracture; however, the level of neck fracture was almost the same. In men, crude rates for both trochanteric and cervical fractures slightly increased. Conclusions As the age of patients increases, fractures were shown to be more complicated. Given the scale of the phenomenon and its determinants, we emphatically conclude orthogeriatrics is needed in Poland.

      Abstract: Background Sarcopenia is a geriatric syndrome characterized by the presence of low muscle mass and function. Possible mechanisms underlying sarcopenia include oxidative stress and elevation of inflammatory cytokines. Aims The aim of the study was to evaluate the relationship between sarcopenia and biomarkers that may be involved in its pathogenesis and hence early detection. Methods A total of 72 patients (36 sarcopenic and 36 non-sarcopenic) were included in the study. An experienced geriatric team applied comprehensive geriatric assessment to all patients. Anthropometric measures, gait speed and handgrip strength were recorded. Bioelectrical impedance analysis was used to assess skeletal muscle mass. In addition to routine clinical laboratory tests, serum adiponectin, thioredoxin-1 and pentraxin-3 levels were measured. Sarcopenia was defined according to the European Working Group on Sarcopenia in older Adults as the presence of low muscle mass and low muscle function or muscle performance. Results Sarcopenic patients were more likely to be functionally dependent and had lower scores on comprehensive geriatric assessment tools. Erythrocyte sedimentation rate (ESR) and C-reactive protein levels were significantly higher in the sarcopenic group. There was no significant difference in serum levels of thioredoxin-1 and pentraxin-3. Sarcopenic patients had lower levels of hemoglobin, albumin, total protein, calcium, triglycerides, uric acid and adiponectin (p < 0.05). Hypertension and body mass index were inversely correlated with sarcopenia whereas ESR was positively correlated. Discussion and conclusion The present study demonstrated an association of sarcopenia with inflammatory markers CRP, ESR and adiponectin. Long-term prospective studies are warranted to confirm the relationship between markers oxidative stress and age related muscle decline.

    • Authors: Mariangela Rondanelli; Roberto Aquilani; Manuela Verri; Federica Boschi; Evasio Pasini; Simone Perna; Anna Faliva; Anna Maria Condino
      Pages: 801 - 805
      Abstract: Abstract This investigation compares the levels of plasma kinetics of plasma essential amino acids (EAAs) after ingestion as free-form EAAs (FEAAs) or EAAs as components of dietary protein (DPEAAs), in eighteen healthy individuals, nine elderly (85 ± 6.7 years; 4 male) and nine young (28.7 ± 7 years; 3 males). For two consecutive days, each subject ingested EAAs in the form of (FEAAs) or (DPEAAs) in a random alternate pattern. Five minutes before EAA ingestion (baseline) and 30, 60, 90, 150 and 270 min after, venous blood samples were taken to determine the concentrations of EAAS (micromol/L). In both groups, ingested FEAAs compared to DPEAAs led to faster increase in plasma EAA levels at 30–150 min (p < 0.0001). Moreover, the increased plasma EAAs disappeared faster after FEAA compared to DPEAA. These results may be important in those subjects who have high requirement both for EAAs substrates and anabolic efficiency.

    • Authors: Francesco Curcio; Giuseppe Sasso; Ilaria Liguori; Gaetana Ferro; Gennaro Russo; Michele Cellurale; David Della-Morte; Gaetano Gargiulo; Gianluca Testa; Francesco Cacciatore; Domenico Bonaduce; Pasquale Abete
      Abstract: Abstract Traditional risk factors of cardiovascular death in the general population, including body mass index (BMI), serum cholesterol, and blood pressure are also found to relate to outcomes in the geriatric population, but in a differing direction. A higher body mass index, hypercholesterolemia and hypertension are not harmful but even permit better survival at advancing age. This phenomenon is called “reverse epidemiology” or “risk factor paradox” and is also detected in a variety of chronic disease states such as chronic heart failure. Accordingly, a low BMI, blood pressure and cholesterol values are associated with a worse prognosis. Several possible causes are hypothesized to explain this elderly paradox, but this phenomenon remains controversial and its underlying reasons are poorly understood. The aim of this review is to recognize the factors behind this intriguing phenomenon and analyse the consequences that it can bring in the management of the cardiovascular therapy in elderly patient. Finally, a new phenotype identified as “catabolic syndrome” has been postulated.

  • Why older people stop to drive' A cohort study of older patients
           admitted to a rehabilitation setting
    • Authors: Christian Pozzi; Elena Lucchi; Alessandro Lanzoni; Simona Gentile; Sara Morghen; Marco Trabucchi; Giuseppe Bellelli; Alessandro Morandi
      Abstract: Abstract The aim of this study is to describe the predictive factors of driving cessation at 6-month follow-up in older patients discharged from a rehabilitation setting and evaluated by an occupational therapist in a multidisciplinary team. Of 95 patients, at 6-month 27.4% ceased to drive. The reasons for driving cessation were a patients’ voluntary choice (42.3%) or a choice of their family (23.1%), and only in 34.6% of the patients the license was revoked by a medical commission. In a multivariate analysis greater functional impairment—measured with the Timed Up and Go test—(OR 12.60, CI 2.74–57.89; p < 0.01) was the only predictor of driving cessation. This study shows that the ability to walk safely and independently is a significant predictor of driving cessation. The simple assessment of this factor using the TUG might be an easy screening tool to prompt a second level evaluation to accurately identify unsafe driving.

  • Effects of a 10-week multimodal exercise program on physical and cognitive
           function of nursing home residents: a psychomotor intervention pilot study
    • Authors: Catarina Pereira; Hugo Rosado; Ana Cruz-Ferreira; José Marmeleira
      Abstract: Background Nursing home institutionalization tends to exacerbate loss of functioning. Aims Examine the feasibility and the effect of a psychomotor intervention—a multimodal exercise program promoting simultaneous cognitive and motor stimulation—on the executive (planning ability and selective attention) and physical function of nursing home residents. Methods Seventeen participants engaged in a 10-week multimodal exercise program and 17 maintained usual activities. Results Exercise group improved planning ability (25–32%), selective attention (19–67%), and physical function [aerobic endurance, lower body strength, agility, balance, gait, and mobility (19–41%)], corresponding to an effect size ranging from 0.29 (small) to 1.11 (high), p < 0.05. Discussion The multimodal exercise program was feasible and well tolerated. The program improved executive and physical functions of the nursing home residents, reverting the usual loss of both cognitive and motor functioning in older adult institutionalized. Conclusions Multimodal exercise programs may help to maintain or improve nursing home residents’ functioning.

      Abstract: Introduction Various operational definitions have been proposed to assess the frailty condition among older individuals. Our objective was to assess how practitioners measure the geriatric syndrome of frailty in their daily routine. Methods An online survey was sent to national geriatric societies affiliated to the European Union Geriatric Medicine Society (EUGMS) and to members of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO). Results A total of 388 clinicians from 44 countries answered to the survey. Most of them were medical doctors (93%), and their primary field of practice was geriatrics (83%). Two hundred and five clinicians (52.8%) always assessed frailty in their daily practice, 38.1% reported to “sometimes” measure it, and 9.1% never assess it. A substantial proportion of clinicians (64.9%) diagnose frailty using more than one instrument. The most widely used tool was the gait speed test, adopted by 43.8% of the clinicians, followed by clinical frailty scale (34.3%), the SPPB test (30.2%), the frailty phenotype (26.8%) and the frailty index (16.8%). Conclusion A variety of tools is used to assess frailty of older patients in clinical practice highlighting the need for standardisation and guidelines.

  • Psychometric characteristics of the Spanish version of the Barthel Index
    • Authors: Nerea González; OFF (Older Falls Fracture)-IRYSS group; Amaia Bilbao; Maria Joao Forjaz; Alba Ayala; Miren Orive; Susana Garcia-Gutierrez; Carlota Las Hayas; Jose Maria Quintana
      Abstract: Background The Barthel Index is one of the most employed questionnaires for the evaluation of functionality, but there is no information on its psychometric properties. Objective The aim was to evaluate the reliability, validity, and responsiveness of the Spanish version of the Barthel Index. Methods The data employed in this paper were obtained from four Spanish cohorts of elderly people of 60 years or older. We collected data on age, gender, education level, comorbidities, and questionnaires regarding functionality, health-related quality of life, depression, and social support. Results The Cronbach’s alpha coefficients were greater than 0.70. The confirmatory factor analysis provided satisfactory fit indexes and factor loadings. The correlation coefficients between the Barthel Index and the other questionnaires were lower than the Cronbach’s alpha coefficients. Known-groups validity showed significant differences in the Barthel Index according to age, number of comorbidities, and gender. The standardized effect size and the standardized response mean were between 0.68 and 1.81. Discussion This version of the Barthel Index has good reliability, its structural validity has been confirmed, and the questionnaire can discriminate between groups and detect changes at follow-up points. Conclusions This questionnaire can be used in the evaluation of functionality and basic activities of daily living in elderly people with different conditions.
