RESUMO
Polypharmacy, i.e. the prescription of five or more different drugs for medicinal treatment, is a typical problem in older and geriatric patients. Polypharmacy predisposes to different negative health sequelae, such as undesired side effects, drug interactions, potentially inappropriate medication, reduced functional abilities, increased hospitalization and increased mortality. Various consensus groups and specialist societies have developed recommendations on how to handle polypharmacy in geriatric patients. Although concepts to reduce the number of drugs are considered necessary, in many areas there is a lack of evidence on how to limit polypharmacy in geriatric patients and to reduce and discontinue medication. This article presents examples of recent studies dealing with potentially inappropriate medication, vitamin D substitution and antipsychotic drugs, which show how to critically appraise a prescribed medication, to critically check the indications for drugs and to discontinue drug use.

AIM: The objective of this pilot study was to determine the accuracy of point-of-care B-line lung ultrasound in comparison to NT Pro-BNP for screening acute heart failure. MATERIALS AND METHODS: An 8-zone lung ultrasound was performed by experienced sonographers in patients presenting with acute dyspnea in the ED. AHF was determined as the final diagnosis by 2 independent reviewers. RESULTS: Contrary to prior studies, B-line ultrasound in our study was highly specific, but moderately sensitive for identifying patients with AHF. There was a strong association between elevated NT-proBNP levels and an increased number of B-lines. CONCLUSION: In conclusion, point-of-care lung ultrasound is a helpful tool for ruling in or ruling out important differential diagnoses in ED patients with acute dyspnea.
RESUMO
DNA methylation changes are a constant feature of acute myeloid leukemia. Hypomethylating drugs such as azacitidine are active in acute myeloid leukemia (AML) as monotherapy. Azacitidine monotherapy is not curative. The AML-AZA trial tested the hypothesis that DNA methyltransferase inhibitors such as azacitidine can improve chemotherapy outcome in AML. This randomized, controlled trial compared the efficacy of azacitidine applied before each cycle of intensive chemotherapy with chemotherapy alone in older patients with untreated AML. Event-free survival (EFS) was the primary end point. In total, 214 patients with a median age of 70 years were randomized to azacitidine/chemotherapy (arm-A) or chemotherapy (arm-B). More arm-A patients (39/105; 37%) than arm-B (25/109; 23%) showed adverse cytogenetics (P=0.057). Adverse events were more frequent in arm-A (15.44) versus 13.52 in arm-B, (P=0.26), but early death rates did not differ significantly (30-day mortality: 6% versus 5%, P=0.76). Median EFS was 6 months in both arms (P=0.96). Median overall survival was 15 months for patients in arm-A compared with 21 months in arm-B (P=0.35). Azacitidine added to standard chemotherapy increases toxicity in older patients with AML, but provides no additional benefit for unselected patients.

In colorectal cancer (CRC), an increase in the stromal (S) area with the reduction of the epithelial (E) parts has been suggested as an indication of tumor progression. Therefore, an automated image method capable of discriminating E and S areas would allow an improved diagnosis. Immunofluorescence staining was performed on paraffin-embedded sections from colorectal tumors (16 samples from patients with liver metastasis and 18 without). Noncancerous tumor adjacent mucosa (n = 5) and normal mucosa (n = 4) were taken as controls. Epithelial cells were identified by an anti-keratin 8 (K8) antibody. Large tissue areas (5-63 mm(2)/slide) including tumor center, tumor front, and adjacent mucosa were scanned using an automated microscopy system (TissueFAXS). With our newly developed algorithms, we showed that there is more K8-immunoreactive E in the tumor center than in tumor adjacent and normal mucosa. Comparing patients with and without metastasis, the E/S ratio decreased by 20% in the tumor center and by 40% at tumor front in metastatic samples. The reduction of E might be due to a more aggressive phenotype in metastasis patients. The novel software allowed a detailed morphometric analysis of cancer tissue compartments as tools for objective quantitative measurements, reduced analysis time, and increased reproducibility of the data.

BACKGROUND: Community-acquired pneumonia (CAP) is still an important and serious disease for elderly and geriatric patients. AIMS: For epidemiological and clinical reasons it is important to collate the frequencies of the various degrees of severity of CAP and to obtain information on the spread and degree of the threat to the various risk groups by CAP. In outpatient treatment a simple to execute prognosis score can be used to objectify the assessment of the clinical status of a patient and to support therapeutic decision-making. For this purpose knowledge of the appropriate instruments should be available to potential users. MATERIAL AND METHODS: Since the 1990s a variety of risk scores for stratification of CAP have been developed and evaluated. This article presents the content and value of the available risk scores whereby the advantages and disadvantages of the individual scores are critically compared. Special emphasis is placed on the importance of the risk scores for geriatric patients. RESULTS: At present the decision about outpatient or inpatient treatment is primarily based on the risk score CRB-65. Criteria for intensive care unit admissions are provided by the modified American Thoracic Society (ATS) set of criteria. Overall, risk scores are less reliable for elderly patients than for younger adults. CONCLUSION: For treatment decisions for the elderly, functional aspects should also be considered in addition to the aspects of risk scores discussed here. In particular, the decision about inpatient admission for elderly, geriatric CAP patients should be made on an individual basis taking the benefit-risk relationship into consideration.

BACKGROUND: The prevalence of delirium in hospitalized patients is high, but delirium is frequently not identified by treating physicians in emergency departments (EDs). Although the number of elderly patients admitted to EDs is increasing, no data on prevalence, identification and outcome of delirious elderly patients in German EDs exist. OBJECTIVES: To evaluate the prevalence and identification of delirium in elderly patients in a German ED and to identify characteristics of delirium in elderly ED patients. METHODS: Evaluation of data from a prospective single-center observational study. The study was conducted in the interdisciplinary ED of an urban university-affiliated hospital receiving approximately 80,000 visits per year. The shortened Confusion Assessment Method (CAM) was used to screen 133 consecutive ED patients, aged 75 years and older, for delirium. Comorbid conditions were ascertained by patient interview and review of medical records. Data concerning patient mortality and current living status were collected 28 days after the ED visit in a structured telephone interview. RESULTS: A positive CAM result was recorded in 14.3 % of cases; 68.4 % of these CAM-positive patients were not identified as being delirious by the ED physician. The 28-day mortality was higher among patients with delirium. Dependency on external help, polypharmacy, pre-existing cognitive or mobility impairments and the presence of any care level were strongly associated with delirium. CONCLUSION: Elderly patients with known risk factors should be routinely assessed for delirium in the ED with a standardized assessment tool such as the CAM.

BACKGROUND: Single or frequent falls lead to increased morbidity due to fall-related injury, fear of falling, impairments in quality of life and loss of independence. To assess the impact of falls, prevalence data are essential. METHODS: In 2006, a telephone survey was performed in a random sample of 1270 inhabitants of the city of Herne, Germany, aged 40 years or older. Participants were asked about falls during the previous 4 weeks and 6 and 12 months, respectively. A fall was defined as an unexpected event in which the individual comes to rest on the ground, floor or a lower level. Participants were also asked about pain and whether or not a medical diagnosis of osteoporosis had ever been made. Standardized prevalences and odds ratios (OR) with 95 % confidence interval are reported. RESULTS: In total, 862 (67.9 %) adults participated. Participants were significantly older than non-participants and more often female than male. Prevalences standardized for the population of Herne for at least one fall within the previous 4 weeks or 12 months or two or more falls within 12 months, respectively, were 3.1 %, 12.1 %, and 4.5 %. Women were more often affected than men. A total of 2.3 % participants reported both at least one fall and a medical diagnosis of osteoporosis. The prevalence of falls increased with increasing age and was also related to musculoskeletal pain. CONCLUSIONS: Our estimates indicate that single and multiple falls affect a substantial proportion of adults in the urban population. Risk groups such as older adults and females with osteoporosis might represent a target group when considering measures for fall prevention.

Programmes containing health-enhancing physical exercise should be evaluated using standards that are just as rigorous as those required for drug development. In contrast to new medicines, exercise programmes are highly complex. This has to be taken into account when designing the research plan. In order to illustrate the development process of a "complex intervention", we use the example of an exercise programme for community-dwelling, mobility-restricted and chronically ill older adults. Based on a framework for evaluation of complex interventions (Medical Research Council [MRC], UK), a research plan was set up containing the phases: development, feasibility, evaluation, implementation. The development phase resulted in the design of a home-based exercise programme in which the target group is approached and supported via their general practitioner and an exercise therapist. A feasibility study was performed. Three quantitative criteria for feasibility (adoption, safety, continuing participation) were statistically confirmed which permitted the decision to proceed with the research plan. So far, the MRC framework has proved to be valuable for the development of the new programme.

Potentially inappropriate medication (PIM) in the elderly is a common problem in primary care. Depending on the setting under investigation, recent studies reported a prevalence of PIM up to 24% in Germany. In 2010 the German national PRISCUS list containing explicit criteria to identify PIM was published. First data show a possible association between PIM as defined by the Priscus list and negative health outcomes. However, prospective controlled trials are needed to assess whether interventions based on explicit criteria are able to improve patient-related outcome. Against this backdrop, the present review comments on recent data, especially those with impact for the German health care system.

For the treatment of geriatric inpatients, the efficacy of a multimodal geriatric intervention based on findings of a comprehensive geriatric assessment has well been established. Therefore, the focus of elderly inpatient care switched to the identification of geriatric patients who have unintended or unscheduled contact to an accident and emergency department. In Germany, a uniform standard on how to correctly identify geriatric patients in such settings has yet to be established.Three medical societies, the Federal Association of Geriatrics ("Bundesverband Geriatrie", BVG), the German Society for Gerontology and Geriatrics ("Deutsche Gesellschaft für Gerontologie und Geriatrie", DGGG) and the German Geriatrics Society ("Deutsche Gesellschaft für Geriatrie", DGG) have reached a consensus on tools and instruments for the identification of geriatric patients in the emergency care setting. Basis of the consensus were the existing scientific evidence and further considerations, especially the applicability of international findings in Germany and feasibility.Three recommendations are made: (1) The use of prognostic indices is not recommended, as prognostic indices appear to be inappropriate to disclose the complex needs of geriatric patients. (2) Comprehensive geriatric assessment is established and effective, but too complex for use in the emergency setting. It is recommended for cases in which information from screening instruments or other sources does not allow a clear decision. (3) Among screening instruments, the Identification of Seniors At Risk (ISAR) screening tool seems to be well established and suitable for screening purposes in Germany. A German adaption is recommended as well as the implementation in settings where no other tools or geriatric expertise are available.

BACKGROUND: The German questionnaire PRISCUS-PAQ was developed to measure actual physical activity of older adults in a telephone interview. PRISCUS-PAQ consists of ten main questions to assess the time spend in domestic activities (e.g., housework, gardening), sporting activities (e.g., riding a bicycle), and inactivity (e.g., sedentary activity, sleeping during the day) during the prior week. By assessing the number of days for each activity and the mean duration of performing this activity, a total score can be calculated. The total score corresponds to the energy consumption for 1 week. The aim of this study is to estimate the correlation of the PRISCUS-PAQ total score and accelerometry as an objective measurement method for the assessment of physical activity. MATERIAL AND METHODS: A total of 114 participants (58% women) with a mean age of 76 years participated in the study. PRISCUS-PAQ was initially analyzed descriptively. To assess the validity of PRISCUS-PAQ, the correlation (correlation coefficient of Spearman) was calculated between the total score of the questionnaire PRISCUS-PAQ and the 95% trimmed sum of an accelerometer with a measurement period of 1 week. RESULTS: The correlation coefficient for the association of the PRISCUS-PAQ total score and the 95% trimmed sum of the acceleration values was r = 0.28 (95% confidence interval 0.100.44). Activities of daily life like cleaning and other domestic activities highly contributed to the weekly energy consumption of the participants. CONCLUSION: The association between the PRISCUS-PAQ questionnaire and accelerometry measured physical activity is comparable to other validated and established international questionnaires. The PRISCUS-PAQ is the first German questionnaire that allows the measurement of physical activity of older adults in a telephone interview.

BACKGROUND: To assess cognitive impairment or dementia in epidemiologic studies using telephone interviews for data acquisition, valid, reliable and short instruments suitable for telephone administration are required. For the Telephone Interview for Cognitive Status (TICS) in its modified German version, the only instrument used in Germany so far, more data on reliability and practicability are needed. MATERIAL AND METHODS: Participants were recruited in the offices of nine primary care physicians. Data from 197 participants (115 females, mean age 78.5±4.1 years) who were tested by telephone and in the office by means of the Mini-Mental State Examination (MMSE) were used for the evaluation. For assessing reliability, a group of 91 participants (55 females, mean age 78.1±4.1 years) was contacted twice during 30 days to be tested during a telephone interview by means of the TICS in its modified German version. RESULTS: The intraclass correlation coefficient (ICC), a measure of reliability, was 0.67 [95% confidence interval (CI): 0.53; 0.77]. The Bland-Altman plot did not reveal any relationship between the variability of the difference between repeated measures and the total amount of the measure. For the overall TICS score, no differences were found between repeated measurements. However, the tasks recall of the word list and counting backwards showed some improvement in the repeated tests. TICS and MMSE showed only moderate correlation, with a correlation coefficient of 0.48 (95% CI: 0.36; 0.58). TICS values were dependent on age and educational level of the person tested. CONCLUSIONS: The TICS in its modified German version appears to be of acceptable reliability for the assessment of cognitive impairment during a telephone interview. TICS values depend on age and educational level of the person tested. TICS and MMSE correlate only moderately.

BACKGROUND: Aspiration pneumonia is associated with a high morbidity and mortality in elderly patients. In order to provide risk-adapted medical care, it is necessary to establish valid prognostic tools for these patients. OBJECTIVE: The value of two well-established scores to assess prognosis in community-acquired pneumonia (CAP), i.e., CURB-65 and the Pneumonia Severity Index (PSI), was evaluated in elderly patients hospitalized for aspiration pneumonia. MATERIAL AND METHODS: A total of 209 patients hospitalized with aspiration pneumonia between 2001 and 2005 in a single center were evaluated using PSI and CURB-65. For comparison of morbidity and mortality, an equally large group of inpatients with CAP was analyzed. RESULTS: The mean age of patients with aspiration pneumonia was 76.7 ± 13.4 years, and 104 (49.8 %) were female. Patients with aspiration pneumonia more frequently showed a history of cancer, hypotension, and hyponatriemia on admission. Mortality was clearly higher in comparison to patients with CAP (39.2% vs. 16.3%). The Odds Ratio (OR) for mortality was 1.03 (95% CI 0.59; 1.79) for a CURB-65 score of 3-5 points compared to 0-2 points. In cases of CAP, OR showed a statistically significant increase of risk (OR 2.50; 95% CI 1.04; 6.06), for CURB-65 scores of 3-5 points vs. 0-2 points). In aspiration pneumonia, the PSI showed a trend towards increasing mortality within higher risk class. CONCLUSIONS: In geriatric patients hospitalized with aspiration pneumonia, CURB-65 and PSI have no prognostic value.

BACKGROUND: Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis causing endothelial dysfunction, an early sign of atherogenesis. Symmetric dimethylarginine (SDMA) does not inhibit NO synthases. Peripheral arterial disease (PAD) is a systemic indication of atherosclerosis. METHODS: We assessed the associations between both ADMA and SDMA blood levels and major cardiovascular and cerebrovascular events or death from any cause within a 5-year follow-up in the multicentre getABI trial. From a cohort of 6821 primary care patients, aged ≥65 years, all 1260 patients with prevalent PAD were compared with a random sample of 1187 non-PAD controls. A total of 11,544 patient-years were documented. Multivariate risks were calculated by Cox proportional hazard models, adjusting for PAD, renal dysfunction and other important cardiovascular risk factors. RESULTS: We documented 390 deaths, 296 cardiovascular events and 98 cerebrovascular events. Increased ADMA levels in the 4th quartile were significantly associated with total mortality [hazard ratio (HR) 1.41; 95% CI 1.14-1.74] and with cardiovascular events (HR 1.32; 95% CI 1.03-1.69), but there was a nonsignificant association with cerebrovascular events (HR 1.50; 95% CI 0.98-2.29). Increased SDMA was only just significantly associated with mortality (HR 1.27; 95% CI 1.01-1.59). In PAD patients compared with non-PAD controls, only mean SDMA concentration was considerably increased (0.52 µmol L(-1) vs. 0.48 µmol L(-1); P < 0.001) mainly because of a highly significant association with impaired renal function. CONCLUSION: These data suggest that ADMA but not SDMA is an independent risk marker for death from any cause or from cardiovascular events. The association between SDMA and mortality is in part explained by a close link between SDMA and renal function.

BACKGROUND: Multimorbidity, the concurrent manifestation or presence of multiple chronic conditions, poses huge challenges to affected patients, their relatives, physicians, and practitioners alike. The growing number of affected persons and the complexity of their needs places just as much of a burden on the health care system as does the plethora of often poorly coordinated interventions. The Chronic Care Model developed for different chronic diseases is suited for improving medical care. The PRISCUS research consortium was established to create the prerequisites for a new care model for multimorbid, elderly patients oriented along those lines. METHODS: The research consortium utilizes data gathered in a large-scale epidemiological study on peripheral arterial disease (getABI study) and from the Dortmund and Münster stroke registries, by extracting epidemiologic and health economic data, quality-of-life parameters, and data on the extent and quality of medication. Additional projects evaluate the implementation of a multidimensional geriatric assessment in primary care, the functional consequences of multimorbidity in stroke patients along with options for prevention and therapy afforded by physical activity. Systematic reviews of the literature are used to describe quality of life and patient preferences. Experts will work on an initial draft treatment standard for patients with multimorbidity and a list of potentially inappropriate medication for the elderly in Germany. CONCLUSION: The results of the PRISCUS research consortium will enable an epidemiologic characterization and description of consequences of multimorbidity, while illustrating new approaches towards prevention, diagnosis, and management of multimorbid patients. With this, some prerequisites for a new health care model for patients with multimorbidity comparable to the Chronic Care Model will be fulfilled.

BACKGROUND: The concurrent presence or manifestation of multiple chronic conditions, i.e. multimorbidity, poses a challenge to affected patients and their relatives, physicians, and practitioners, and to the health care system in general. Aiming to improve medical care for different chronic diseases, the Chronic Care Model also appears to be suited for multimorbidity. The established research consortium PRISCUS is trying to create some of the prerequisites for a new care model for multimorbid, elderly patients oriented along the lines of the Chronic Care Model. METHODS AND RESULTS: Four out of seven subprojects of the research consortium provide an overview of some of their findings. Topics in a sports medicine subproject were the assessment of physical activity by means of a newly developed questionnaire and the development and feasibility testing of an exercise program for elderly people with chronic conditions and mobility impairment. Partners from family medicine implemented geriatric assessment in a primary care setting and evaluated its consequences. In a pharmacological subproject, potentially inappropriate medication as well as drug-drug interactions and dosing errors were addressed. The health economic subproject investigated quality of life impairment due to multiple chronic diseases and the effects of multimorbidity on costs. CONCLUSIONS: The results of the PRISCUS research consortium allow a better description of consequences of multimorbidity and illustrate at least some new approaches towards prevention, diagnosis, and treatment of patients suffering from multimorbidity. Ongoing projects will test the efficacy of a physical activity program and a new complex intervention to reduce potentially inappropriate medication in the elderly. With this, the research consortium will create some prerequisites for a new health care model for patients with multimorbidity comparable to the Chronic Care Model.

A questionnaire (Q) to measure physical activity (PA) of persons ≥70 years for epidemiological research is lacking. The aim was to develop the PRISCUS-PAQ and test the reliability in community-dwelling people (≥70 years). Validated PA questionnaires were translated and adapted to design the PRISCUS-PAQ. Its test-retest reliability for 91 randomly selected people (36% men) aged 70-98 (76±5) years ranged from 0.47 (walking) to 0.82 (riding a bicycle). The overall activity score was 0.59 as determined by the intraclass correlation coefficient (ICC). Recording of general activities, e.g., housework (ICC=0.59), was in general less reliable than athletic activities, e.g., gymnastics (ICC=0.76). The PRISCUS-PAQ, which is a short instrument with acceptable reliability to collect the physical activity of the elderly in a telephone interview, will be used to collect data in a large cohort of older people in the German research consortium PRISCUS.

BACKGROUND: Musculoskeletal pain is among the most common symptoms in the population and osteoarthritis is the most important underlying disease. Due to demographic changes, an increase in problems with arthritis is to be expected. To assess the impact on individuals affected and the community, data on the prevalence of musculoskeletal pain and osteoarthritis are essential. METHODS: We performed a telephone survey in a sample of 1,270 inhabitants of the City of Herne, Germany, aged 40 years and older. Participants were asked to give their experience on musculoskeletal pain at the time of the questionnaire and during the last 4 weeks and 12 months. Further questions were whether the knee or hip were the site of most severe pain and if osteoarthritis was ever diagnosed by a physician. Standardized prevalences are reported according to age. RESULTS: A total of 862 (67.9%) persons participated and participants were significantly older and more often female. Musculoskeletal pain on the day of the questionnaire, during the past 4 weeks and the past 12 months was reported in 37.4%, 53.0% and 60.0%, respectively. The knee and hip were predominantly affected in 35.9% and 16.1%, respectively and 26.2% reported that a physician had previously diagnosed osteoarthritis. The prevalences were related to age and gender. CONCLUSIONS: Musculoskeletal pain and osteoarthritis affect an important part of the adult urban population. We found associations between self-reported musculoskeletal pain, osteoarthritis, age and gender. Further studies should evaluate the interference of pain with activities of daily living as well as the use of health services by affected patients.

A field study was performed on 32 male deep drilling workers engaged in hard physical work and 10 male operators with mainly supervisory tasks; both groups working in a shiftwork system including 12 hr shifts. Both the analysis and evaluation of stresses and strains were carried out by means of physiological, psychological and sociological methods. The obtained results show that under the conditions of the given working requirements, existing reproduction conditions, and observed social structure of the populations operating and supervisory activities in a 8 hr shiftwork system including 12 hr shifts are acceptable. In case of hard physical work this shiftwork arrangement can't be agreed to for industrial-medical reasons.
