Red blood cell counts and indices in the elderly German population

Background: Data on peripheral blood cell values in older subjects are rare. While hemoglobin (Hb) values are supposed to change with rising age, little is known about reference values for other erythrocytic blood cell counts. This cross-sectional study was initiated to analyze hematologic laboratory parameters among subjects aged >= 60 years. Methods: This was a retrospective cross-sectional study of outpatient laboratory data between January 1st and December 31st, 2015 originating from a German country-wide laboratory group; inclusion criteria: age >= 60 years, normal C-reactive protein (CRP), transferrin saturation, reticulocytes, lactate dehydrogenase, haptoglobin and soluble transferrin receptor; exclusion criteria: glomerular filtration rate (GFR) = 60 years, 4641 met the inclusion criteria and were thus considered hematologically healthy; the following age groups were formed: 60-69 years (2094), 70-79 years (2171), 80-89 years (360), >90 years (16); median values for male/female subjects were: Hb 15.2/14.0 g/dL, RBC 5.0/4.6/mu L, mean cellular volume (MCV) 89/89/fl, mean corpuscular hemoglobin (MCH) 31/30 pg/RBC, mean corpuscular hemoglobin concentration (MCHC) 34/34 g/dL, hematocrit (hct) 44/41%. Statistical evaluation revealed a slight but significant decrease in values over age decades for all parameters except for MCH. However, all values remained within the recommended German Society of Hematology and Oncology (DGHO) reference ranges. Hb values remained above the recommended World Health Organization (WHO) cutoffs for definition of anemia. Conclusions: The results confirm the WHO reference values and are in accordance with the recommended DGHO reference values and previous results of other study cohorts outside Germany. There seems to be no need for establishing age-specific RBC or erythrocytic reference ranges for subjects >60 years

Testosterone Deficiency and Testosterone Treatment in Older Men

Frailty is a clinical condition related to changes in metabolism, to sarcopenia, and to decline in muscle mass and strength, bone mineral density, and physical function with aging. The pathophysiology of frailty is multifactorial and associated with comorbidities. Testosterone is implicated in regulating metabolic functions, maintenance of muscle and bone, and inhibition of adipogenesis. In older individuals, reduced testosterone is thought to contribute to an altered state of metabolism, loss of muscle and bone, and increased fat, leading to sarcopenia, sarcopenic obesity, and frailty. While no direct relationship between testosterone deficiency (commonly known as hypogonadism) and frailty has been established (due to the multifactorial nature of frailty), clinical evidence suggests that testosterone deficiency is associated with increased sarcopenia and obesity. Testosterone treatment in frail older men with limited mobility and with testosterone deficiency improved insulin resistance, glucose metabolism, and body composition. These changes contribute to better physical function and improved quality of life. Because frailty increases disability, comorbidities, and the risk of hospitalization, institutionalization, and mortality in older men, it is warranted to explore the potential usefulness of testosterone treatment in frail men with hypogonadism in order to attenuate the progression of sarcopenia and frailty. In this paper, we will discuss the impact of testosterone deficiency on frailty and the potential role of testosterone treatment in ameliorating and reducing the progression of frailty. Such an approach may reduce disability and the risk of hospitalization and increase functional independence and quality of life. (C) 2016 S. Karger AG, Base

Prevalence of anemia among elderly inpatients and its association with multidimensional loss of function

The purpose of this cross-sectional prospective study was to determine the prevalence of anemia among elderly hospitalized patients in Germany and to investigate its association with multidimensional loss of function (MLF). One hundred participants aged 70 years or older from two distinct wards (50 each from an emergency department and a medical ward, respectively) underwent a comprehensive geriatric assessment (CGA) consisting of the following six tools: Barthel Index, mini-mental state examination, clock-drawing test, timed up and go test, Esslinger transfer scale, and Daniels test. MLF as an aggregated outcome was diagnosed when three or more tests of the CGA showed an abnormal result. Anemia was defined according to WHO criteria as a hemoglobin (Hb) concentration of < 13 g/dL for men and < 12 g/dL for women. The prevalence of anemia was 60 %. Overall, 61 % of patients presented with three or more abnormal results in the six tests of the CGA and, thus, with MLF. Using logistic regression, we found a significant association of both anemia and low Hb concentrations with abnormal outcomes in five tests of the CGA and, therefore, with domain-specific deficits like mobility limitations, impaired cognition, and dysphagia. Furthermore, being anemic increased the odds of featuring MLF more than fourfold. This significant relationship persisted after adjustment for various major comorbidities. Both anemia and geriatric conditions are common in the hospitalized elderly. Given the association of anemia with MLF, Hb level might serve as a useful geriatric screening marker to identify frail older people at risk for adverse outcomes

Xerostomia and hyposalivation in orthogeriatric patients with fall history and impact on oral health-related quality of life

Purpose: Falls are a common cause of morbidity and mortality in older people, and identification of risk indicators and risk factors to prevent falling is essential. Dry mouth (xerostomia and hyposalivation) can exacerbate conditions known to be fall risk indicators, such as nutritional status and sarcopenia. But there is little evidence regarding whether it is an independent risk factor for falling. We explored xerostomia prevalence and intensity and objective salivation rates in hospitalized geriatric patients to determine whether they were associated with an increased risk of falling. Patients and methods: Hospitalized geriatric patients with and without a fall history were compared. We investigated several oral health issues including xerostomia, stimulated and unstimulated salivation rates, total number of teeth and prosthetics, periodontal status, and oral health-related quality of life. Results: Forty patients were included, 28 in the fall history group and 12 in the control group. All patients had oral health issues that impacted on their oral health-related quality of life. However, there were no significant differences between the groups, including xerostomia and hyposalivation, apart from increased dysphagia and less flavor in food in patients with a fall history. Conclusion: Dry mouth does not appear to be an independent risk factor for falling in this population, but oral health was impaired. Thus, it is important that dentists and geriatricians are aware of and investigate these conditions in their patients and that appropriate action is taken to reduce the consequences of impaired oral health, including a potential reduction in falls

Burden of multimorbidity and outcome in ambulatory geriatric hemodialysis patients Report from the QiN registry in Germany

Patients with end-stage renal disease (ESRD) requiring hemodialysis are typically characterized by multimorbidity and increasingly by advanced age; however, there are few data on their geriatric needs. The aim of the study was to evaluate the clinical characteristics of a large cohort of incident patients in ambulatory hemodialysis units with a particular focus on those aged over 80 years in Germany. The electronic patient registry of the Board of Trustees (Kuratorium) for Dialysis and Kidney Transplantation (KfH) was searched for all patients who began hemodialysis in 1 of the 191 units between 2007 and 2013 and were 65 years and older. Patients were analyzed by age (65-79 years and >= 80 years) for clinical and biochemical characteristics, mortality, quality of life and hospitalizations. Of the 21,355 incident patients, a total of 13,872 (65%) were over 65 years old, with 9998 (46.8%) aged between 65 and 79 years and 3874 (18.1%) patients 80 years or older (oldest old). The spectrum of morbidity was comparable between the two age groups but there was a significantly higher prevalence of anemia, hypoalbuminemia and multimorbidity (> four comorbidities) in the older age group. Median survival was 4.5 years (1638 days) in the younger age group and 2.7 years (978 days) in the older group. Almost half of the patients experienced at least one episode of hospitalization during the first year but there were no significant differences between the age groups (45.9% in younger vs. 47% in older patients). In the older age group 463 (12%) patients survived more than 5 years after initiation of hemodialysis despite the presence of multiple risk factors for adverse clinical outcome. More than half of the chronic ambulatory hemodialysis patients were of advanced age and had a very high burden of multimorbidity. Nevertheless, a subgroup of ERSD patients over 80 years old survived at least 5 years on hemodialysis despite the presence of multiple risk factors for adverse clinical outcome. Identification of these patients as well as optimized care for frail hemodialysis patients will require application of geriatric assessment tools in addition to traditional parameters in nephrology. The development and validation of such tools should be the subject of further clinical studies

Interdisciplinary assessment and management of a patient with a fibrous gingival enlargement of unknown origin: A case report

A gingival enlargement of unclear cause could only be diagnosed after interdisciplinary cooperation as plasma cell gingivitis of unknown origin. Interdisciplinary approaches remain crucial when diagnosing rare gum diseases

Do subjectively and objectively impaired oral health parameters influence geriatric assessment results in hospitalized geriatric patients?

Background Impaired oral health affects oral health-related quality of life (OHrQoL) in orthogeriatric hospitalized patients, and both might be associated with potential risk factors for functional impairment, based on the comprehensive geriatric assessment (CGA) and related blood laboratory values. As data on this field are scarce, we investigated possible associations between oral health, items of the geriatric oral health assessment instrument (GOHAI), CGA assessment tools, and relevant laboratory values. Methods Explorative cross-sectional pilot study investigating oral and general health, OHrQoL, and functionality based on objective oral health, GOHAI, CGA, and routinely assessed laboratory parameters of orthogeriatric patients. Correlations (Spearman's rho and Pearson's) and regression analysis were performed for the dependent variables functionality, cognition, Mini-Nutritional Assessment, Falls Efficacy Scale (FES), and the 15-item geriatric depression scale (GDS). Results Among all participants (N = 40), several GOHAI single items (GOHAI 1,4,5,7,10,11) correlated with certain CGA assessment results (fear of falling, Barthel index, handgrip power). Reduced subjective oral health (GOHAI, xerostomia) and objective oral health (oral hygiene index, root caries index, unstimulated salivation rate) correlated with reduced general health and CGA results (polypharmacy, handgrip power, FES, GDS). Anemia was seen in all participants, but no associations between reduced oral health and laboratory blood values were detected. Conclusion Our results demonstrate the association between impaired subjective and objective oral health, OHrQoL, and physical functional impairment among orthogeriatric patients. Impaired GOHAI item results at the dentist, and the association between GOHAI values and CGA results that implies an association between physical and oral health, should encourage a geriatric check based on CGA, and vice versa. Results encourage interdisciplinary cooperation between geriatricians and dentists, but also indicate the need for further research in this field. Key summary pointsAim To verify the hypothesis that there is an impact of objective and subjective oral health parameters on CGA results, which is reflected by laboratory parameters. Findings In our limited study group, associations between oral health parameters, OHrQoL, and CGA could be shown, but there were no associations with routine laboratory parameters. Message Our results demonstrate the association between impaired oral health, OHrQoL, and physical functional impairment among orthogeriatric patients. The results encourage interdisciplinary cooperation between geriatricians and dentists, but also indicate the need for further research in this field

Oral health assessment of seniors under outpatient care by family doctors Development and validation of the geriatric outpatient oral health screening

Background Despite a high prevalence in the general practitioner (GP) and geriatric field, limitations of oral health of seniors under outpatient care in Germany are not routinely recorded. Since seniors with a high age visit GPs more often than dentists, the question arises whether an interdisciplinary screening instrument can be used to identify reduced oral health in routine practice. Objective The aim of the work was to develop a screening tool for reduced oral health for GPs and to validate this by dental examinations. Material and methods The geriatric outpatient oral health screening (GAMS) was developed as a subjective screening instrument to depict dental aspects relevant for geriatric patients, such as chewing problems, pain, periodontitis, bad breath or dry mouth in dichotomous questions. The urgency of a visit to the dentist is also assessed by the family doctor. A total of 75 patients were included and the GAMS and a dental examination were performed for validation. Results The subjective assessment of patients and dental findings showed reduced oral health especially with recognized risk factors for the development of systemic comorbidities, such as dysphagia and malnutrition, whereas oral health problems were underestimated by patients. Bites, chewing problems and dry mouth showed sufficient correspondence between dental findings and subjective assessment. Conclusion The GAMS could help facilitate the consideration of oral health problems in geriatric patients in a GP setting and promote cooperation with dentists in the sense of European recommendations for action

Intravenous iron administration in restless legs syndrome An observational study in geriatric patients

This observational study was carried out to investigate the effect of intravenous (i.v.) iron administration on the clinical symptoms of restless legs syndrome (RLS) in geriatric outpatients over 65 years old. In this study geriatric outpatients (mean 4.5 +/- 3.4 comorbidities and 5.7 +/- 4.4 drugs taken) were recruited according to the following inclusion criteria: aeyenaEuroe65 years, diagnosis of RLS due to iron deficiency, i.e. ferritin < 50 A mu g/l or transferrin saturation (TFS) < 16 %) as well as no other iron therapy within 2 weeks prior to the study. Of the patients 7 (41 %) received 500 mg ferric carboxymaltose (FCM) and 10 patients (59 %) received iron gluconate (62.5 mg) based on the degree of iron deficiency. As assessed by the international RLS severity scale (IRLS) symptoms were recorded 3 times: at the beginning of iron therapy (t(0)), after 2 weeks (t(1)) and after 12 weeks (t(2)). A total of 17 patients (13 female, 4 male, mean age 73.2 +/- 5.9 years) were included. The IRLS score significantly improved in all patients as shown by an average decrease from 30.2 (+/- 4.3) to 20.2 (+/- 4.7) (p < 0.001) after 2 weeks of i.v. iron treatment and to 23.2 +/- 6.6 (p < 0.001) after 12 weeks. There was a high correlation between ferritin values and the IRLS score (C 0.729, p < 0.001). The part of the IRLS referring to activities of daily living (ADL) improved from a median of 3 (scores 3-4) to 2 (scores 2-3, p = 0.001) after 2 weeks (effect size -aEuroe0.6). In this study group of geriatric outpatients i.v. administration of iron was associated with a significant improvement of symptoms in RLS as assessed by the IRLS score 2 weeks after treatment. In geriatric patients with RLS associated with iron deficiency, i.v. iron administration should be considered regarding improvement of RLS symptoms and ADL

Resting energy expenditure (REE) in an old-old population: implications for metabolic stress

The basis of nutritional therapy and thus an adequate nutrient intake is the assessment of energy need. On the other end, the assessment of individual energy requirements based on the gold standard, indirect calorimetry, is associated with feasibility difficulties in geriatric settings. To identify the most accurate predictive equations for resting energy expenditure (REE) in older subjects with overweight, 17 predictive equations were compared to indirect calorimetry measurement in a study population of 20 obese older subjects (mean BMI 33.7 +/- 4.5 kg/m(2); mean age 79.8 +/- 8.1 years; gender 5 males and 15 females) and 20 age-matched controls with a normal body weight (mean BMI 24.9 +/- 2.5 kg/m(2); mean age 82.1 +/- 6.6 years; gender 9 males and 11 females). The comparison led to two significant observations: the predictive equations used led to a much better estimation of the REE in the control group than in the obese older subjects. In addition, the most accurate equation for estimating the REE in the obese older subjects has been shown to be that by Luhrmann et al. Further studies are needed to assess the feasibility of using this equation in a routine geriatric setting. (C) 2014 The Authors. Published by Elsevier Inc
