Performance in a Balance Test and Prediction of All-Cause Mortality in Community-Dwelling Elderly Ambulatory Individuals: A Systematic Review and Meta-analysis.

Objective: This systematic review and meta-analysis was performed to evaluate the association between an inability to perform a static balance test and mortality in community-dwelling older ambulatory individuals. Methods: PubMed, Embase, and Scopus were searched for relevant cohort studies. Hazard ratios (HR) were pooled (random-effect model). Meta-regression was performed with independent demographic variables (PROSPERO ID: CRD42022381137). Results: A total of 11,713 articles were screened and 15 were included. An inability to perform a static balance test was significantly associated with a higher risk of mortality irrespective of whether confounding variables were considered [HR, 1.14 (95% CI: 1.07-1.21); p < .001; i2, 87.96% (p < .01)] or not [HR, 1.11 (95% CI: 1.03-1.20); p = .01; i2, 95.28% (p < .01)] (both moderate GRADE evidence). Also, this association was correlated with progressive age. Conclusion: An inability to successfully complete a static balance test was significantly associated with a higher risk of mortality among community-dwelling older ambulatory individuals.

Abnormal Gait and Tremor Detection in the Elderly Ambulatory Behavior Using an IoT Smart Cane Device

In this paper, a novel approach for abnormal gait and tremor detection using a smart walking cane is introduced. Periodic muscle movement associated with Parkinson’s disease, such as arm shaking, vibrating arm, trembling fingers, rhythmic wrist movements, normal and abnormal walking pattern, was learned and classified with linear discriminant analysis. Although detecting symptoms related to disease with walking sticks might look trivial at first, throughout history, a cane or walking stick has been used as an assistive device to aid in ambulating, especially in the elderly and disabled, so embedding smart devices (that can learn ambulating pattern and detect anomalies associated with it) in the cane will help in early detection of diseases and facilitate early intervention. This approach is non-intrusive, and privacy issues being experienced in visual models do not arise, as users do not need to wear any special bracelet or wrist monitoring, and they only need to pick up the cane when they wish to move. The simplicity and efficient usage of a technique for detecting ambulatory anomalies is also demonstrated in this research. We extracted step counts, fall data and other valuable features from the cane, and detected anomalies by using isolation forest and one-class support vector machine (SVM) methods. Falls were detected easily and naturally with the cane, which had different alert modes (a soft alert when the cane lost equilibrium and was picked up within 15 s, and a strong alert otherwise). Intervention systems are proposed to forestall and limit the possibility of a type 2 error.

Medication Appropriateness, Polypharmacy, and Drug-Drug Interactions in Ambulatory Elderly Patients with Cardiovascular Diseases at Tikur Anbessa Specialized Hospital, Ethiopia.

BackgroundAppropriate prescribing is often challenging in geriatric patients due to age-related pharmacokinetic and pharmacodynamic alterations. Elderly patients with cardiovascular diseases are frequently prescribed multiple medications. Hence, it is imperative to investigate medication appropriateness, polypharmacy, and drug-drug interactions in these groups of patients.ObjectiveTo assess medication appropriateness using the 2019 American Geriatric Society Beers and Medication Appropriateness Index criteria, polypharmacy and drug-drug interactions among elderly ambulatory patients with cardiovascular diseases at Tikur Anbessa Specialized Hospital.MethodsA hospital-based retrospective cross-sectional study was conducted among 384 elderly (60 years and older) ambulatory patients with cardiovascular diseases between May 01-August 30, 2021. Data was collected from the patient’s medical record using a data abstraction tool. The data were entered and analyzed using the SPSS program. Descriptive and logistic regression models were used to present the findings.ResultsThe most frequent diagnosis was hypertension (78.4%) followed by ischemic heart disease (31.3%). Averagely, 4.4 ± 2 medications were prescribed per patient. More than half of (53.1%) the patients received polypharmacy. According to Beer’s and medication appropriateness index criteria, over one-third (28.1%) and the majority (95.1%) of the patients were prescribed potentially inappropriate medications, respectively. In addition, 53.1% and 90.1% of patients had polypharmacy, and were exposed to potential drug-drug interactions ranging from mild to major interactions, respectively. Further, polypharmacy was significantly associated with inappropriate medication prescribing.ConclusionThe study found that more than half of the patients got one or more potentially inappropriate medications in both criteria. The medication appropriateness index tool identified more potentially inappropriate medication than the Beers criteria. In addition, more than half of the patients got polypharmacy and had potential drug-drug interactions. Further, polypharmacy was significantly associated with inappropriate medication prescriptions. These findings highlight the need for interventions to improve appropriate prescribing practice among elderly patients.

Performance of a cardiac lipid panel compared to four prognostic scores in chronic heart failure

The cardiac lipid panel (CLP) is a novel panel of metabolomic biomarkers that has previously shown to improve the diagnostic and prognostic value for CHF patients. Several prognostic scores have been developed for cardiovascular disease risk, but their use is limited to specific populations and precision is still inadequate. We compared a risk score using the CLP plus NT-proBNP to four commonly used risk scores: The Seattle Heart Failure Model (SHFM), Framingham risk score (FRS), Barcelona bio-HF (BCN Bio-HF) and Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score. We included 280 elderly CHF patients from the Cardiac Insufficiency Bisoprolol Study in Elderly trial. Cox Regression and hierarchical cluster analysis was performed. Integrated area under the curves (IAUC) was used as criterium for comparison. The mean (SD) follow-up period was 81 (33) months, and 95 (34%) subjects met the primary endpoint. The IAUC for FRS was 0.53, SHFM 0.61, BCN Bio-HF 0.72, MAGGIC 0.68, and CLP 0.78. Subjects were partitioned into three risk clusters: low, moderate, high with the CLP score showing the best ability to group patients into their respective risk cluster. A risk score composed of a novel panel of metabolite biomarkers plus NT-proBNP outperformed other common prognostic scores in predicting 10-year cardiovascular death in elderly ambulatory CHF patients. This approach could improve the clinical risk assessment of CHF patients.

Assessment of Knowledge and reasons for Medication non-Adherence in Ambulatory Elderly Patients with Hypertension and Diabetes Mellitus in a Geriatric Centre in Nigeria

Abstract Introduction Hypertension and type 2 Diabetes mellitus are global health disorders afflicting millions of elderly patients worldwide with an ever-increasing incidence and prevalence. Non-adherence to medications affects the quality and length of life, and has been associated with negative health outcomes and increasing healthcare costs especially in the elderly [1]. Few empirical data exist on the knowledge and medication adherence among elderly patients in sub-Saharan Africa countries. Aim This study aimed to assess the knowledge, medication adherence, and the factors associated with patient’s knowledge on diabetes mellitus and hypertension. Methods A cross-sectional study of 423 elderly patients aged ≥60 years diagnosed with hypertension and diabetes mellitus, selected consecutively at the Geriatric centre in the University College Teaching Hospital, Ibadan was carried out between October 2019 and January 2020. Socio-demographic information, knowledge of the indication of the medications, possible side effects, and details of medication adherence level with reasons for non-adherence were obtained using interviewer-administered semi-structured questionnaire. Bivariate and multivariate analyses were carried out using SPSS 23. Alpha was set at 0.05. Results The mean age (±SD) of the older patients was 69.6 ± 6.4 years and 253 (59.8%) were females. About three-quarter of participants (320; 75.7%) were retired. Majority of the elderly (381; 90.1%) were hypertensive, while 270 (63.8 %) were diabetic, and 85 (20.1%) had multimorbidity of both hypertension and diabetes mellitus. Patients that were non-adherent with their medication were 138 (32.6%). The most common reasons reported for non-adherence included patient slept off (41; 56.6%), pre-occupation (24; 33.1%) and unavailability of medications (12; 16.6%). Thirty-seven (8.7%) participants intentionally missed doses, out of which 22 (59.5%) reported pill burden as its reason for medication non-adherence. All patients 423 (100.0%) knew the indication for their medications and 20 (4.7%) experienced medication-related side effects. Overall, 299 (70.6%) and 309 (73.0%) of patients with hypertension and diabetes mellitus showed good knowledge about their conditions. Adherence to medication was associated with good knowledge in hypertensive patients (p=0.002), while being male (p=0.002), age-group of 60–69 (p=0.001) and poor adherence (p=0.001) were associated with good knowledge in diabetes mellitus patients. Conclusion We found non-adherence was mainly as a result of patients’ behaviors, attitude, and unavailability of medications which could be the cause of low medication adherence among the elderly patients. A systematic review on factors associated with medication adherence in older patients reported medication review aimed at simplifying regimens and educating patients about their treatment as intervention to improve adherence [2]. Thus, we recommend educational intervention among the elderly patients. The elderly patients demonstrated good knowledge about their conditions and medication. However, the relatively good knowledge did not appear to have significant impact on patient’s adherence to medication. Improvement in medication adherence through interdisciplinary approach may improve clinical outcomes.

Interleukin-6 Could Be a Potential Prognostic Factor in Ambulatory Elderly Patients with Stable Heart Failure: Results from a Pilot Study.

Introduction: Inflammation is a fundamental phenomenon in heart failure, but the prognostic or therapeutic role of markers such as interleukin-6 (IL-6) has not yet been clarified. The objective of this study is to describe the clinical profile of patients with elevated IL-6 and determine if they have worse clinical outcomes. Methods: A retrospective c.ohort observational study including 78 patients with heart failure followed up at the Heart Failure Outpatient Clinic of the Internal Medicine Department. IL-6 was determined in all patients, who were then assigned into two groups according to IL-6 level (normal or high). Clinical and prognostic data were collected to determine the differences in both groups. Results: The average age was 79 years, 60% female. A total of 53.8% of the patients had elevated IL-6 (group 2). Patients with elevated IL-6 presented more frequently with anemia mellitus (64.3% vs. 41.7%; p = 0.046), atrial fibrillation (83.3% vs. 61.9% p = 0.036), dyslipidemia (76.2% vs. 58.2%; p = 0.03), higher creatinine levels (1.35 mg/dL vs. 1.08 mg/dL; p = 0.024), lower glomerular filtration rate (43.6 mL/min/m2 vs. 59.9 mL/min/m2; p = 0.007), and anemia 25% vs. 52.4% p = 0.014. The factors independently associated with the increase in IL-6 were anemia 3.513 (1.163–10.607) and renal failure 0.963 (0.936–0.991), p < 0.05. Mortality was higher in the group with elevated IL-6 levels (16% vs. 2%; p = 0.044) with a log-rank p = 0.027 in the Kaplan–Meier curve. Conclusion: Patients with heart failure and elevated IL-6 most often have atrial fibrillation, diabetes mellitus, dyslipidemia, anemia, and renal failure. In addition, mortality was higher and a tendency of higher hospital admission was observed in stable HF patients with elevated IL-6.

Anti-Cholinergic Drug Burden Among Ambulatory Elderly Patients in a Nigerian Tertiary Healthcare Facility.

Background: The use of drugs with anticholinergic effects among elderly patients is associated with adverse clinical outcomes. There is paucity of information about anticholinergic drug burden among Nigerian elderly population. Objectives: To determine the anticholinergic drug burden among elderly Nigerian patients. Methods: This was a retrospective cross-sectional study conducted among elderly patients (aged 65 and above) who visited the Family Medicine outpatients’ clinics of the Ekiti State University Teaching Hospital, Ado-Ekiti, Nigeria between July 1 and October 31, 2018. Information extracted from the case files included patient’s age, sex, diagnoses, and list of prescribed medications. Medicines with anticholinergic effects were identified and scored using the anticholinergic drug burden calculator (http://www.acbcalc.com). Results: The medical records of 400 patients were analyzed with females accounting for 60.5% of the study population. The mean age of participants was 73 ± 7.4 years with only 28 (7%) of patients having more than two co-morbid conditions. Polypharmacy was identified in 152 (38%) of the patients while 147 (36.7%) had drugs with anticholinergic effects prescribed. The anticholinergic burden was high in 60 (15%) patients. Polypharmacy was significantly associated with having more than two diagnosed conditions and high anticholinergic burden (p value of < 0 .001 and 0.013 respectively). There was significant correlation between total number of prescribed drugs and count of diagnoses (r = 0.598; p < 0 .000) and between total number of prescribed drugs and number of drugs with anticholinergic effects (r = 0 .196; p < 0 .000). Conclusion: The anticholinergic burden in this group of elderly Nigerian patients was low; majority (67%) had no exposure to drugs with anticholinergic effects with only 15% having high anticholinergic burden. Polypharmacy and multiple diagnosed conditions were positively associated with high anticholinergic burden. Based on the positive and significant correlations found in this study, a reduction in the number of prescribed medicines especially those with significant anticholinergic effects used for secondary indications may lessen the anticholinergic burden among the elderly.

Extracto dosificado de arándano rojo: una terapia eficaz para la cistitis recurrente por Escherichia coli en pacientes de la tercera edad. El estudio GerHogar Cysticlean®

Introducción: la cistitis es la infección del tracto urinario más común a nivel mundial y los antibióticos son su terapia convencional; sin embargo, la tasa de prevalencia de la resistencia de los uropatógenos a los antibióticos ha aumentado significativamente en los últimos tiempos. El tratamiento con arándano rojo se ha asociado con la inhibición de la adherencia de la Escherichia coli a las células uroepiteliales debido a la propiedad antiadherente relacionada con su contenido de proantocianidinas. La cysticlean® (CYS) es un extracto de arándano rojo que contiene 240 mg de PAC por cápsula. Objetivo: estudiar la eficacia y seguridad de la CYS en el tratamiento de la cistitis como reemplazo de los antibióticos en personas adultas mayores. Materiales y métodos: se estudiaron dos grupos, uno (G1) en el que el primer episodio de cistitis se registró dentro de los últimos 3 meses antes del inicio del estudio y otro (G2) en el que se registraron episodios recurrentes de cistitis frecuentes (?1-2 al mes) en los últimos 3 meses antes del inicio del estudio. Los pacientes del G1 fueron tratados con 1 cápsula de CYS cada 12 horas durante 1 mes, mientras que los del G2 fueron tratados por 12 meses con el mismo esquema. La evaluación comparativa se realizó mediante la prueba de Student. Resultados: en el estudio participaron 160 pacientes ambulatorios de la tercera edad residentes de hogares de ancianos y con diagnóstico de cistitis recurrente. De estos, 38 se incluyeron en G1 y 122, en G2. El tratamiento de la cistitis a base de arándano rojo tuvo éxito en el 81,57 % y el 81,96 % de los pacientes de G1 y G2, respectivamente. Conclusión: la CYS demostró ser una terapia alternativa eficaz a los antibióticos para tratar las recurrencias de cistitis causadas por E. coli al no presentarse efectos secundarios ni reacciones adversas.

Effect of a Multicomponent Exercise Program (VIVIFRAIL) on Functional Capacity in Elderly Ambulatory: A Non-Randomized Clinical Trial in Mexican Women with Dynapenia.

During aging, loss of muscle strength (dynapenia) combined with unhealthy lifestyles and sedentarism can lead to functional limitations and dependency; currently there is still limited evidence about multicomponent training as a treatment for dynapenia and dependence in ambulatory older women. To evaluate the effect of a multicomponent physical exercise program (VIVIFRAIL) on physical functionality in elderly ambulatory women with dynapenia. A non-randomized clinical trial was realized in 61 ambulatory older women (65-80 years old) with dynapenia that belonged from two Integral Gerontological Centers (IGC) of Hidalgo, Mexico, from June to December 2019. The control group (CG) received the physical daily training applied in the IGC (yoga, cardio-dance or tai chi) and the intervention group (IG) participated in a multicomponent program training (resistance, flexibility, balance and gait) called "VIVIFRAIL" for 12 weeks, minimum 3 weekly sessions of 45-60 minutes. All participants were evaluated at baseline (0 weeks), intermediate (6 weeks) and final (12 weeks), evaluations included glucose, blood pressure (SBP and DBP), anthropometric test, body composition evaluation and functional performance test with Short Physical Performance Battery (SPPB), Timed Up and Go Test (TUGT), muscle strength and a falls risk short test. 52 older women completed the study, mean age was 71.9 ± 4.46. According to SPPB passport classification was 1 Type A, 1 Type B+, 9 Type C, 7 Type C+ and 9 Type D. After 12 weeks of intervention, statistical analysis showed that multicomponent exercise significantly improved strength (p=<0.001), gait speed (p<0.001), standing from a chair (p<0.001) and TUGT (p<0.001). About falls risk, intervention group went from 70% to 12.5% while control group went from 52.4% to 63.6% (p<0.05). Older women who completed the 12 weeks multicomponent exercise program significantly improved their functionality in muscle strength, gait speed (3mt and 6mt), standing from a chair and TUGT tests. Also, it showed a significantly decrease in falls risk, therefore, this type of intervention can reduce the risk of frailty in the elderly.

Potentially Inappropriate Prescriptions in Ambulatory Elderly Patients Living in Rural Areas of Romania Using STOPP/START (Version 2) Criteria.

BackgroundRational use of medications and monitoring of prescriptions in elderly patients is important to decrease the number and duration of hospitalizations, emergency medical consultations, mortality, as well as medical costs.PurposeTo identify potentially inappropriate medications (PIMs) and potential prescription omissions (PPOs), and determine their prevalence based on the Screening Tool of Older Persons’ potentially inappropriate Prescriptions (STOPP) v2 criteria and Screening Tool to Alert doctors to Right Treatment (START) v2 criteria for patients aged >65 years.MethodsThis cross-sectional study was conducted in two rural counties in Romania based on electronic prescriptions for chronic conditions (EPCCs) issued from 30 days to 90 days by a specialist or general practitioner. Collected EPCCs were evaluated by an interdisciplinary team of specialists based on 26 STOPP v2 criteria and 10 START v2 criteria.ResultsPIM prevalence was 25.80% and PPO prevalence was 41.72% for 646 EPCCs. The mean age of patients was 75 years and the mean number of drugs per EPCC was four. The most frequently identified PIMs were treatment duration (6.65%), theophylline administration (5.72%), drug indication (4.64%), cyclo-oxygenase-2 non-steroidal anti-inflammatory drugs (1.39%), and zopiclone prescription (0.77%). Statins (24.76%), beta-blockers (8.04%), and beta-2 agonist/antimuscarinic bronchodilators (5.88%) were the most frequently identified PPOs.ConclusionPPOs were more prevalent than PIMs for elderly populations living in the two rural counties in Romania we studied. Health practitioners (family physicians, specialists, and pharmacists) should focus on prophylactic and curative considerations when prescribing agents to decrease the morbidity and mortality of elderly rural Romanian patients.

Potentially Inappropriate Medications in Elderly Ambulatory Patients: A Comparative Study between a Primary Health Care Center and a Community Pharmacy

ObjectiveThis study aims to compare, both qualitatively and quantitatively, the medication dispensed to elderly patients in a primary health care center (PHC) and a community pharmacy (CP) in Argentina and to identify the prescription of potentially inappropriate medications (PIMs). MethodsA cross-sectional observational study. Data were acquired from 886 prescriptions in the PHC and 2368 in the CP between February and April 2015. Dispensed medications were coded according to the Anatomical, Therapeutic, and Chemical (ATC) classification system. The frequency of prescriptions for each of them was determined. The number and monthly average of drugs dispensed were calculated for each patient. The use of PIMs was identified using Beers Criteria. ResultsIn both institutions, the means of medications dispensed per individual and month were similar: 3.69 ± 1.93 in the PHC and 3.46 ± 2.18 in the CP. Most of the medications corresponded to cardiovascular system agents. In the CP, 111 prescriptions (4.69%) dispensed to 51 patients (19.39%) were identified as PIMs. In the PHC, 72 prescriptions (8.13%) dispensed to 27 patients (28.42%) were identified as PIMs. In patients with major polymedication the possibility of consuming these drugs was 2.55 times higher in the CP and 2.60 times higher in the PHC. The percentage of PIM prescriptions was significantly higher in the PHC, although the percentage of patients receiving them did not differ significantly. ConclusionsThe prevalence of PIMs found in this population is relevant enough to implement measures that address the problem in an integral way, to improve the quality of prescriptions and the health outcomes of patients.

Non-Steroidal Anti-Inflammatory Drugs Prescription in Elderly Ambulatory Patients

Non-steroidal antiinflammatory drugs (NSAID) are widely used medications in elderly ambulatory patients despite their numerous side effects. The NSAID prescription by 6 general practitioners (GPs) working in a single center to ambulatory patients aged 65 years or older was retrospectively evaluated. Individual interviews of the 6 GPs were performed by means of qualitative questionnaires to determine NSAID prescription habits, knowledge of NSAID by doctors, knowledge of Good Clinical Practice (GCP) recommendations. We then conducted a retrospective observational study in 154 patients aged 65 years or older who received at least one NSAID given orally between October 1st and December 31st of 2014, by means of a questionnaire including 34 validated evaluation criteria according to the current guidelines. The 6 GPs did not frequently prescribe NSAID in their patients aged 65 years or older, due to the high number of co-prescribed drugs, renal or liver insufficiency, and the high risk of side effects in these patients. Their knowledge regarding the side effects, contra-indications and warnings of the various available NSAIDs are heterogeneous and none of the interviewed GPs were aware of available GCP recommendations regarding NSAIDs prescription and side effects prevention in older patients. 10.5% of the 154 patients had a prescription of at least one NSAID. However, this prescription was in agreement with the market authorization recommendation in only 72% of cases. Numerous gaps were identified between daily practice of these GPs and the available GCP recommendations, except for the recommendations regarding gastrointestinal side effects and contra-indications of the NSAID, which were highly respected. GCP recommendations for NSAIDs prescription are unknown from prescribers and respect of these recommendations should be improved by means of a patient-dedicated follow-up file designed to optimize the management and prevention of NSAID-related side effects in daily practice.

Potentially inappropriate medications in elderly ambulatory and institutionalized patients: an observational study.

BackgroundThe elderly are frequently exposed to drug related problems causing hospitalizations and increased costs of care. Information about Romanian prescribing practices among the elderly and potential medication associated- risks is lacking. The objective of this study was to identify and compare the most frequent potentially inappropriate medications (PIM) recommended to ambulatory and institutionalized Romanian elderly, through an observational retrospective design.MethodsAll reimbursed medications prescribed to a sample of ambulatory elderly accessing two community pharmacies and all medications recommended to a group of institutionalized elderly (urban facilities, Romania, same month) were analyzed. The STOPP/START criteria and the PRISCUS list were used for PIM identification and for classification as misprescribed, underprescribed or overprescribed -subtypes.ResultsThe analysis involved 345 prescriptions recommended to ambulatory elderly and 91 medical files available for the institutionalized patients. The ambulatory elderly had a mean age of 74.8 years old and were daily exposed to a median number of 3 prescribed medications. The institutionalized elderly were older (mean age 80.77) received 8 medications daily and 69 % of them were functionally dependent. Cardiovascular and neuropsychiatric indications were the most frequent: 64.34 % and 18.55 % of the ambulatory prescriptions, 93.40 % and 41.75 % of the institutionalized patients’ medical files. 159 PIM were identified on 34.49 % of the ambulatory prescriptions. 82.41 % of the institutionalized patients’ medical files contained 140 PIM. The potential underprescribing of cardiovascular therapies was the most frequent PIM category on the ambulatory prescriptions (55.34 % of all PIM), while for the institutionalized patients’ medical files, the misprescribed and overprescribed PIM were those predominantly represented (62.14 % and 27.14 % of all PIM). In both subgroups of data, NSAIDs (56.66 % of ambulatory prescriptions and 35.63 % of institutionalized patients’ data) and benzodiazepines (26.66 % of ambulatory prescriptions and 24.13 % of institutionalized patient’s data) were predominantly misprescribed. Anticholinergics were rarely used (0.62 % of total PIM from ambulatory prescriptions, 2.14 % of total PIM from institutionalized patients’ data).ConclusionsThe PIM identified in both elderly groups suggested potential risks for the occurrence of adverse events specific to the elderly population. Larger studies, both observational and interventional, are needed to ensure a safer therapeutic approach.

Identifying Malnutrition in an Elderly Ambulatory Rehabilitation Population: Agreement between Mini Nutritional Assessment and Validated Screening Tools.

Malnutrition is common in older adults and often goes unrecognised and untreated. Australian evidence-based guidelines for the management of malnutrition indicate that only the Mini Nutritional Assessment short form (MNA-sf) and Rapid Screen are recommended for use as malnutrition screening tools in the rehabilitation setting. The aim of this secondary analysis was to assess the validity and reliability of two malnutrition screening tools, validated in other adult sub-groups, in a rehabilitation population aged ≥60 years. The Council on Nutrition Appetite Questionnaire (CNAQ) and the Simplified Nutritional Appetite Questionnaire (SNAQ), were completed by 185 ambulatory rehabilitation patients (48% male; median age 78 years) and results compared to the full MNA as a reference technique. Prevalence of risk of malnutrition was 63% according to the MNA. For identification of risk of malnutrition the CNAQ had sensitivity of 54%, specificity 81%, positive predictive value 83% and negative predictive value 51%, compared to 28%, 94%, 89% and 44%, respectively, using SNAQ. Assessment of reliability indicated significant slight to fair agreement between MNA with CNAQ (κ = 0.309, p < 0.001) and SNAQ (κ = 0.176, p < 0.001). Neither the CNAQ nor the SNAQ have a high level of validity or reliability in this elderly population and are therefore not recommended for use in the ambulatory rehabilitation setting. Further work is necessary to assess the validity and reliability of other malnutrition screening tools to establish their usefulness in this population.

Study of the Relationship between Vitamin D Status and Basic Functional Mobility in Ambulatory Elderly

Background : Associations between physical performance and vitamin D status have been contradicted among studies. Vitamin D deficiency is very common among geriatric patients and is an established risk factor for osteoporosis, falls and fractures.
