Ultrasonographic/regional muscle measurements for diagnosing sarcopenia in older adults with and without dementia.

BACKGROUND: Sarcopenia and dementia are growing concerns among older adults that muscle and brain atrophy may cooccur. We aimed to compare the age-related loss of muscle mass by using ultrasound (US), and skeletal muscle mass index (SMI) by bioelectrical impedance analysis in older adults with and without dementia. METHODS: A total of 221 older adults aged ≥65 years were included in the study. The diagnosis of sarcopenia was established if low muscle mass according to either SMI or sonographic gastrocnemius (GC) muscle thickness was combined with low grip strength. The diagnosis of dementia was based on the National Institute of Aging and Alzheimer's Association criteria and the major neurocognitive disorder definition in the Diagnostic and Statistical Manual of Mental Disorders-V. Muscle strength was measured by hand dynamometer and physical performance was assessed by 4-meter usual gait speed. RESULTS: There were similar/moderate correlation coefficients between GC muscle thickness and SMI with functional parameters (all p < 0.01). Forty-six patients (20.8%) had dementia, and 21 (45.7%) of them had sarcopenia diagnosed by GC thickness (p < 0.001). Age was older but weight, body mass index, and all sarcopenia-related parameters were lower in dementia patients (all p < 0.01). When clinical variables were taken into binary logistic regression analyses, age [OR = 1.095 (95% CI: 1.028-1.167)], weight [OR = 0.918 (95% CI: 0.887-0.950)], and presence of dementia [OR = 5.109 (95% CI: 2.002-13.033)] were independently associated with sarcopenia diagnosed with GC muscle thickness (all p < 0.05). DISCUSSION: This study showed that sarcopenia is highly prevalent in older adults with dementia (45.7%) than without dementia (11.4%). Amongst different factors, increased age, having low body weight, and the presence of dementia independently increased the risk of sarcopenia diagnosed by GC muscle thickness (but not diagnosed by SMI) in older adults. Thus, we can evaluate easily and successfully the loss of (regional) muscle mass in dementia patients by using US in outpatient clinics.

Delirium, dementia, and depression (3D) assessment of older patients in the emergency department: 5-year survival analysis.

BACKGROUND: While physicians tend to emphasize on physical medical problems, behavioral and cognitive disorders of geriatric patients are usually missed, especially in emergency settings. The aim of the study was to determine the prevalence of delirium, dementia, and depression (3D) among older patients (≥65 years old) in the Emergency Department (ED) and to evaluate the effect of geriatric 3D on the 6-month and 5-year mortality. METHODS: This was a prospective, observational cohort study, including 415 patients from eligible 512 consecutive older patients, who are 65 years of age or older, presenting to the ED of a tertiary care university hospital. Geriatric delirium, dementia, and depression were prospectively evaluated using Confusion Assessment Method, Quick Confusion Scale, and Geriatric Depression Scale-15, respectively. Premorbid functional status was determined by Barthel Index. The Charlson Comorbidity Index was used to measure the comorbid burden. After enrollment, patients were screened for 6-month and 5-year survival rates via the Government Death Reporting System records. The Kaplan-Meier method and Cox proportional hazards analysis was used for survival analysis. RESULTS: Among the study population, the prevalence of geriatric 3D was found as 10.6% (n = 44/415) for delirium, 45.6% (n = 160/351) for dementia, and 35.1% (n = 123/350) for depression. Delirium, dementia, and depression all had higher mortality rates among older ED patients covering the 5-year period. However, only delirium was predictive of both 6-month and 5-year mortality rates. DISCUSSION: Aside from the medical and surgical issues of geriatric patients, the prevalences of dementia and depression are much higher than expected in the emergency department. Delirium was a predictor for 6-month and 5-year mortality. We suggest that EDs should have screening tools for geriatric 3D mental health disorders to increase the quality of life for the geriatric population.

Is frailty a prognostic factor for critically ill elderly patients?

AIM: The study aimed to investigate the effects of frailty on clinical outcomes of patients in an intensive care unit (ICU). METHODS: In this prospective study, 122 patients (59 frail, 37 pre-frail and 26 robust) were included. A frailty index (FI) derived from comprehensive geriatric assessment parameters was used for the evaluation. The FI score of ≤0.25 was considered as robust, 0.25-0.40 as pre-frail and >0.40 as frail. The prognostic effects of FI were investigated and FI and APACHE II and SOFA scores, the prognostic scores using in ICU, were compared. RESULTS: Median age of the patients was 71 years old and 50.8 % were male. ICU mortality rate and median length of stay (LOS) were 51.6 % and 8 days (min-max: 1-148), respectively. ICU mortality was higher (69.2, 56.8 and 40.7 %, respectively, p = 0.040) and median overall survival was lower in frail group compared to pre-frail and robust subjects (23, 31 and 140 days, p = 0.013, respectively). Long term mortality over 3 and 6 months in frail patients were 80.8 and 84.6 %, respectively and significantly higher than others. Multivariate analysis showed that LOS in ICU (HR 1.067, 95 % CI 1.021-1.114), SOFA score (HR 1.272, 95 % CI 1.096-1.476) and FI (HR 39.019, 95 % CI 1.235-1232.537) were the independent correlates for ICU mortality (p = 0.004, p = 0.002 and 0.038, respectively). There was a weak but statistically significant positive correlation between APACHE II and FI scores (r = 0.190, p = 0.036). CONCLUSIONS: FI may be used as a predictor for the evaluation of elderly patients' clinical outcomes in ICUs.

Serum markers of inflammation and oxidative stress in sarcopenia.

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.

Which parameters affect long-term mortality in older adults: is comprehensive geriatric assessment a predictor of mortality?

BACKGROUND: Determining predictors of mortality among older adults might help identify high-risk patients and enable timely intervention. AIMS: The aim of the study was to identify which variables predict geriatric outpatient mortality, using routine geriatric assessment tools. METHODS: We analyzed the data of 1141 patients who were admitted to the geriatric medicine outpatient clinic between 2001 and 2004. Comprehensive geriatric assessment was performed by an interdisciplinary geriatric team. Mortality rate was determined in 2015. The parameters predicting survival were examined. RESULTS: Median age of the patients (415 male, 726 female) was 71.7 years (53-95 years). Mean survival time was 12.2 years (95 % CI; 12-12.4 years). In multivariate analysis, age (OR: 1.16, 95 % CI: 1.09-1.23, p < 0.001), smoking (OR: 2.51, 95 % CI: 1.18-5.35, p = 0.017) and metabolic syndrome (OR: 2.20, 95 % CI: 1.05-4.64, p = 0.038) were found to be independent risk factors for mortality. MNA-SF scores (OR: 0.84, 95 % CI: 0.71-1.00, p = 0.050) and free T3 levels (OR: 0.70, 95 % CI: 0.49-1.00, p = 0.052) had borderline significance. DISCUSSION: The present study showed that the risk conferred by metabolic syndrome is beyond its individual components. Our findings confirm previous studies on the prognostic role of nutritional status, as reflected by MNA-SF. Serum fT3, a simple laboratory test, may also be used in geriatric outpatient clinics to identify individuals at risk. CONCLUSIONS: The results of the study demonstrated the need for addressing modifiable risk factors such as smoking, metabolic syndrome, and undernutrition in older adults.

Influence of antimuscarinic therapy on cognitive functions and quality of life in geriatric patients treated for overactive bladder.

OBJECTIVES: Incidences of overactive bladder (OAB) and cognitive dysfunction increase with aging. Treatment of OAB with antimuscarinic agents may result in cognitive decline, especially in patients with Alzheimer's disease (AD). The aim of this study is to evaluate the effect of antimuscarinic treatment on cognitive functions, depression, and quality of life (QOL) of patients with OAB. METHODS: This non-interventional prospective observational study was conducted in a geriatric medicine outpatient clinic. Overall, 168 OAB patients were enrolled. Patients were followed up in five groups: oxybutynin, darifenacin, tolterodine, trospium, and control groups. Follow-up visits were done at second, third, and sixth months. Comprehensive geriatric assessment, cognitive and mood assessment, QOL scales (IIQ-7, UDI-6) were performed. RESULTS: Mean age of the patients was 73.5 ± 6.1. Of the 168 patients, 92.3% were female, 83.3% benefited from the treatment, and 37.1% discontinued the medication. Discontinuation rate and frequency of side effects were more frequent in the oxybutynin group. Mini Mental State Examination scores did not decline after treatment, even in AD patients. Geriatric Depression Scale scores, Activities of Daily Living scores, and QOL scores significantly improved after treatment. CONCLUSION: Antimuscarinic agents are effective in OAB treatment. They have a positive impact on daily life activities, depression, and QOL indices. Furthermore, they do not have a negative effect on cognitive function in older adults with or without AD.

Functional disability in Alzheimer disease: a validation study of the Turkish version of the disability assessment for dementia scale.

This study aimed to determine the reliability and validity of the Turkish version of Disability Assessment for Dementia (DAD) scale in the Turkish elderly population with Alzheimer disease (AD). The DAD scale was administered to the primary caregivers of 157 patients (age 77.7 ± 6.8 years) with AD. The Turkish version of the DAD scale showed high internal consistency (Cronbach α = .942), excellent test-retest, and interrater reliability (intraclass correlation coefficient [ICC] = 0.996 and ICC = 0.994, respectively). The DAD scale was significantly correlated with activities of daily living (ADL; Modified Older Americans Research Survey ADL) and instrumental activities of daily living (IADL; Lawton and Brody IADL) scales (r = .89, P < .001 and r = .90, P < .001). Disability Assessment for Dementia had a high negative correlation with the Global Deterioration Scale (GDS; r = -.880, P < .001). Post hoc comparisons with Tukey test showed significant differences in the mean DAD scores in different GDS stages. Construct validity was estimated using total score correlation analyses between the standardized Mini-Mental State Examination (MMSE) and the DAD scale. Results revealed high and significant correlation between MMSE score and DAD scale (r = .812, P < .001). The results of multivariate analysis showed that DAD score was not correlated with gender, education, and age. The DAD total score was affected mostly by GDS, MMSE, and duration of the disease. Turkish version of the DAD scale was found to be a reliable and valid instrument to assess functional disability in Turkish elderly patients with AD. This scale assists caregivers and physicians to decide for proper interventions.

Nurses' and physicians' perceptions of older people and attitudes towards older people: Ageism in a hospital in Turkey.

Abstract Nurses and physicians provide health care for a growing number of older people as a result of the rapid increase in the life expectancies of older people. Health professionals' negative attitudes towards older people affect the quality of health care offered to these individuals. The sample for this study included 110 nurses and 57 physicians working in the medical and surgical clinics of a university hospital. A questionnaire form and the Ageism Attitude Scale (AAS) were used to collect the data. A five-point Likert-type format was utilised for the AAS. The AAS total mean score was 80.02 ± 2.64 for nurses and 83.17 ± 9.09 for physicians. The difference between these mean scores was statistically significant (p < 0.05). For the AAS sub-dimension 'limiting the life of the older people,' the physicians' score (35.14 ± 6.22) was significantly higher than the nurses' score (33.22 ± 3.59). In this study, nurses' and physicians' attitudes, approaches, and considerations were found to be generally positive.

Alzheimer's disease is associated with a low prevalence of hypertension.

BACKGROUND/AIM: Dementia is one of the most common health problems in the world. Alzheimer's disease (AD) is the most common form of dementia. The relation between blood pressure (BP) and dementia has been the subject of numerous epidemiological studies, and midlife hypertension (HT) is a risk factor for AD. The association between BP and risk of dementia is lower in the older population. The aim of this study was to examine the association between the prevalence of HT and AD in elderly individuals. METHODS: In this cross-sectional study, 193 patients with AD and 1,860 patients with normal cognitive function were evaluated. RESULTS: The prevalence of HT was lower in the AD group (60.6 vs. 70.5%; p = 0.005). In multivariate analysis, AD was found to be negatively correlated with HT (OR = 0.649; 95% CI 0.461-0.916). CONCLUSION: The prevalence of HT was lower in patients with AD compared to subjects without AD. Physicians who deal with AD patients must keep in mind that the need for antihypertensive medication may decline during the dementia process.

The evaluation of neutrophil-lymphocyte ratio in Alzheimer's disease.

BACKGROUND/AIM: There is growing consensus in the literature that inflammation plays a significant role in the pathophysiology of Alzheimer's disease (AD). The blood neutrophil-lymphocyte ratio (NLR) is a new, inexpensive and easily applicable marker of inflammation. The aim of this study was to investigate the association between NLR, as an inflammatory biomarker, and AD. METHODS: 241 AD patients and 175 patients with normal cognitive function were evaluated in this study. RESULTS: The mean ± SD NLR of AD patients was significantly higher than that of patients with normal cognitive function (3.21 ± 1.35 vs. 2.07 ± 0.74, p < 0.001, respectively). Receiver operating characteristic curve analysis suggested that the optimum NLR cutoff point for AD was 2.48 with 69.29% sensitivity, 79.43% specificity, 82.30% positive predictive values and 65.30% negative predictive values. Logistic regression analysis showed that elevated NLR (OR: 4.774, 95% CI: 2.821-8.076, p < 0.001) was an independent variable for predicting AD. CONCLUSION: Elderly people with AD have higher NLR than healthy controls. Elevated NLR levels are usually considered as an inflammatory marker. The results of this study suggested that inflammation plays a role in the pathogenesis of AD.

Best Practice Recommendations for Geriatric Dysphagia Management with 5 Ws and 1H.

BACKGROUND: Dysphagia is a geriatric syndrome. Changes in the whole body that occur with aging also affect swallowing functions and cause presbyphagia. This condition may progress to oropharyngeal and/or esophageal dysphagia in the presence of secondary causes that increase in incidence with aging. However, no study has been published that provides recommendations for use in clinical practice that addresses in detail all aspects of the management of dysphagia in geriatric individuals. This study aimed to answer almost all potential questions and problems in the management of geriatric dysphagia in clinical practice. METHODS: A multidisciplinary team created this recommendation guide using the seven-step and three-round modified Delphi method via e-mail. The study included 39 experts from 29 centers in 14 cities. RESULTS: Based on the 5W and 1H method, we developed 216 detailed recommendations for older adults from the perspective of different disciplines dealing with older people. CONCLUSION: This consensus-based recommendation is a useful guide to address practical clinical questions in the diagnosis, rehabilitation, and follow-up for the management of geriatric dysphagia and also contains detailed commentary on these issues.

The adhesion molecules of L-selectin and ICAM-1 in thrombocytosis and thrombocytopenia.

Thrombopoiesis is regulated by a variety of cytokines. Intracellular adhesion molecules are inducible cell-surface glycoproteins that belong to the immunoglobulin superfamily. Cytokines, endothelium and adhesive molecules represent the point of crosstalk in normal and pathological hematopoiesis. With the hypothesis that circulating intracellular adhesion molecule-1 (ICAM-1) and lymhocyte adhesion molecule-1 (L-selectin) concentrations could be changed based on pathological thrombopoiesis resulting in quantitative platelet disorders, we evaluated ICAM-1 and L-selectin levels in patients with thrombocytosis, thrombocytopenia and healthy controls. The L-selectin levels were found to be significantly higher in the thrombocytopenia group compared to the control group. ICAM-1 levels were found to be significantly higher in both thrombocytopenia and thrombocytosis groups compared to control group. Our study corroborates our original hypothesis implying the roles of adhesion molecules in the challenging status of pathological thrombopoiesis.

Turkish inappropriate medication use in the elderly (TIME) criteria to improve prescribing in older adults: TIME-to-STOP/TIME-to-START.

PURPOSE: To improve prescribing in older adults, criterion sets have been introduced from different countries. While current criterion sets are useful to some extent, they do not meet the need in some European countries. Turkish inappropriate medication use in the elderly (TIME) criteria was planned to meet this need. METHODS: In phase 1, the user friendly sets: STOPP/START version2 and CRIME criteria were combined. National experts composed of geriatricians and non-geriatricians were invited to review and comment. In phase 2, thorough literature review was performed and reference-based revisions, omissions, and additions were made. Explanatory additions were added to some criteria to improve application in practice. In phase 3, all working group members reviewed the criteria/explanations and agreed on the final content. RESULTS: Phase 1 was performed by 49 expert academicians between May and October 2016. Phase 2 was performed by 23 working group academicians between October 2016 and November 2018 and included face-to-face interviews between at least two geriatrician members and one criterion-related specialist. Phase 3 was completed between November 2018-March 2019 with review and approval of all criteria by working group academicians. As a result, 55 criteria were added, 17 criteria were removed, and 60 criteria were modified from the first draft. A total of 153 TIME criteria composed of 112 TIME-to-STOP and 41 TIME-to-START criteria were introduced. CONCLUSION: TIME criteria is an update screening tool that differs from the current useful tools by the interactive study of experts from geriatrics and non-geriatrics, inclusion of practical explanations for some criteria and by its eastern European origin. TIME study respectfully acknowledges its roots from STOPP/START and CRIME criteria. Studies are needed whether it would lead improvements in older adults' health.

Alterations of von Willebrand factor and ristocetin cofactor activity during atrial fibrillation.

The aim of this study was to assess the plasma levels of von Willebrand factor antigen and ristocetin cofactor activity, which are well-known markers of endothelial function, in atrial fibrillation (AF) with or without mitral stenosis (MS). Forty-two patients (16 patients with MS and AF [MS(+)AF(+)], 13 patients with nonvalvular AF [MS(-)AF(+)], and 13 patients with MS and sinus rhythm [MS(+)AF(-)]) were included. Von Willebrand factor antigen levels and ristocetin cofactor activities in all participants were assessed. Overall, von Willebrand factor antigen levels and ristocetin cofactor activities in the AF(+) patients were higher than in the AF(-) patients (P = .003 and P = .002, respectively). Von Willebrand factor antigen levels and ristocetin cofactor activities in the 3 groups were found to be different (P = .012 and P = .01, respectively). Von Willebrand factor antigen levels were similar between the MS(+)AF(+) and MS(-)AF(+) groups and were higher than that of the MS(+)AF(-) group. Ristocetin cofactor activity in the MS(-)AF(+) group was significantly higher than in the other 2 groups. The ristocetin cofactor activity and von Willebrand factor antigen levels were significantly higher in diabetic or hypertensive patients than in nondiabetic or normotensive patients. According to the results of this study, circulating von Willebrand factor antigen levels and plasma ristocetin cofactor activities are affected by the presence of AF, MS, and associated comorbidities including type 2 diabetes mellitus and systemic hypertension. Further studies are needed to assess the role of von Willebrand factor antigen and ristocetin cofactor activity in predicting vascular thrombotic events in AF, MS, systemic hypertension, and diabetes mellitus.

White coat effect and its clinical implications in the elderly.

The aim of this study was to investigate the frequency and correlated factors of white coat effect (WCE) in the elderly. Geriatric patients who were known as normotensive and office BP exceeding 140/90 mmHg underwent 24-hour ambulatory blood pressure monitoring (ABPM). Correlation of WCE with clinical parameters, geriatric assessment scales, co-existing diseases, and laboratory results were analyzed. Within 61 patients 72.1% were diagnosed as white coat hypertension (WCH). Independent correlates of systolic WCE were activities of daily living, instrumental activities of daily living scores, creatinine; independent correlate of diastolic WCE was Geriatric Depression Scale score. White coat hypertension constitutes a major part of office-detected hypertension in geriatric patients. Ambulatory blood pressure monitoring should be performed on geriatric patients with office-measured hypertension in order to avoid overtreatment.

Lower bone mineral density in geriatric patients with monoclonal gammopathy of undetermined significance.

The aim of this study was to investigate the prevalence of monoclonal gammopathy of undetermined significance (MGUS) in a geriatric population in Turkey and compare bone mineral densities and related laboratory parameters of MGUS patients with those who do not have MGUS. Among 1,012 patients enrolled, monoclonal band was detected in serum samples of 22 patients (2.17%), most of which were IgG type. Further tests revealed multiple myeloma and lung carcinoma in two patients. The remaining 20 patients were diagnosed with MGUS (1.97%). The clinical and laboratory parameters of patients with and without MGUS were mostly comparable; however, bone mineral density measurements of patients with MGUS were significantly lower than those without MGUS (p = 0.007). We suggest evaluation of geriatric patients with MGUS for the presence of osteopenia/osteoporosis considering the high frequency observed in this study.

Hashimoto's thyroiditis is a frequent occurrence in patients with rheumatic mitral stenosis.

BACKGROUND AND AIM OF THE STUDY: Rheumatic mitral stenosis (RMS), an autoimmune sequel of streptococcal infection, causes significant morbidity and mortality. As Hashimoto's thyroiditis (HT) is recognized as the major form of chronic autoimmune thyroiditis, it was hypothesized that the coexistence of HT and RMS might have an autoimmune origin. The study aim was to examine this possible relationship. METHODS: A total of 55 consecutive patients with RMS was examined and compared to 54 healthy controls with normal echocardiographic findings. All subjects underwent transthoracic echocardiography and thyroid ultrasonography after a complete medical history and laboratory examination. RESULTS: The demographic data of the RMS group (38 females, 17 males; mean age 39.9 +/- 9.3 years) and control group (39 females, 15 males; mean age 39.6 +/- 10.5 years) were similar. HT was found to occur significantly more frequently in RMS patients (n = 16; 29%) than in controls (n = 6; 11%) (p = 0.019) CONCLUSION: The higher frequency of HT in patients with RMS than controls may have genetic associations. Hence, further genetic-based studies should be conducted to provide a better understanding of this suggested relationship.

Risk factors and type of dementia: vascular or Alzheimer?

The most efficient strategy for combating Alzheimer's disease (AD) is to prevent the onset of clinically significant symptoms. Determining the clinical characteristics, risk factors, and indices of cognitive reserve would help in achieving this goal. The aim of this study was to determine the risk factors for AD and vascular dementia (VD) in the elderly and to highlight the importance of risk factor modification in the early diagnosis. Consecutive 1436 patients (mean age=72.7+/-6.9 years, 34.2% male) were enrolled in the study. After a comprehensive geriatric and cognitive assessment, patients were grouped as AD group (n=203), VD group (n=73) and normal cognitive status (NCS) group (n=1160). Thirty-three possibly related factors including demographic characteristics, co-existing diseases and laboratory parameters were examined. The results revealed that female sex, advanced age, depression, and intake of vitamin supplements were independent related factors for AD; whereas depression and low-density lipoprotein-cholesterol (LDL-C) were independent related factors for VD. For every geriatric patient admitted for any reason, cognitive assessment should be performed, risk factors should be determined and the patients at high risk should be followed up carefully.
