Incident Subjective Cognitive Decline Does Not Predict Mortality in the Elderly--Results from the Longitudinal German Study on Ageing, Cognition, and Dementia (AgeCoDe). PLoS One 2016; 11:e0147050.

Abstract
OBJECTIVE Subjective cognitive decline (SCD) might represent the first symptomatic representation of Alzheimer's disease (AD), which is associated with increased mortality. Only few studies, however, have analyzed the association of SCD and mortality, and if so, based on prevalent cases. Thus, we investigated incident SCD in memory and mortality. METHODS Data were derived from the German AgeCoDe study, a prospective longitudinal study on the epidemiology of mild cognitive impairment (MCI) and dementia in primary care patients over 75 years covering an observation period of 7.5 years. We used univariate and multivariate Cox regression analyses to examine the relationship of SCD and mortality. Further, we estimated survival times by the Kaplan Meier method and case-fatality rates with regard to SCD. RESULTS Among 971 individuals without objective cognitive impairment, 233 (24.0%) incidentally expressed SCD at follow-up I. Incident SCD was not significantly associated with increased mortality in the univariate (HR = 1.0, 95% confidence interval = 0.8-1.3, p = .90) as well as in the multivariate analysis (HR = 0.9, 95% confidence interval = 0.7-1.2, p = .40). The same applied for SCD in relation to concerns. Mean survival time with SCD was 8.0 years (SD = 0.1) after onset. CONCLUSION Incident SCD in memory in individuals with unimpaired cognitive performance does not predict mortality. The main reason might be that SCD does not ultimately lead into future cognitive decline in any case. However, as prevalence studies suggest, subjectively perceived decline in non-memory cognitive domains might be associated with increased mortality. Future studies may address mortality in such other cognitive domains of SCD in incident cases.

Abstract
OBJECTIVES To investigate time-dependent predictors of frailty in old age longitudinally. DESIGN Population-based prospective cohort study. SETTING Elderly individuals were recruited via GP offices at six study centers in Germany. The course of frailty was observed over 1.5 years (follow up wave 4 and follow up wave 5). PARTICIPANTS 1,602 individuals aged 80 years and older (mean age 85.4 years SD 3.2, with mean CSHA CFS 3.5 SD 1.6) at follow up wave 4. MEASUREMENTS Frailty was assessed by using the Canadian Study of Health and Aging Clinical Frailty Scale (CSHA CFS), ranging from 1 (very fit) to 7 (severely frail). RESULTS Fixed effects regressions revealed that frailty increased significantly with increasing age (β=.2) as well as the occurrence of depression (β=.5) and dementia (β=.8) in the total sample. Changes in marital status and comorbidity did not affect frailty. While the effects of depression and dementia were significant in women, these effects did not achieve statistical significance in men. CONCLUSION Our findings highlight the role of aging as well as the occurrence of dementia and depression for frailty. Specifically, in order to delay frailty in old age, developing interventional strategies to prevent depression might be a fruitful approach.

Abstract
Objective To investigate time-dependent predictors of institutionalization in old age using a longitudinal approach. Methods In a representative survey of the German general population aged 75 years and older predictors of institutionalization were observed every 1.5 years over six waves. Conditional fixed-effects logistic regressions (with 201 individuals and 960 observations) were performed to estimate the effects of marital status, depression, dementia, and physical impairments (mobility, hearing and visual impairments) on the risk of admission to old-age home or nursing home. By exploiting the longitudinal data structure using panel econometric models, we were able to control for unobserved heterogeneity such as genetic predisposition and personality traits. Results The probability of institutionalization increased significantly with occurrence of widowhood, depression, dementia, as well as walking and hearing impairments. In particular, the occurrence of widowhood (OR = 78.3), dementia (OR = 154.1) and substantial mobility impairment (OR = 36.7) were strongly associated with institutionalization. Conclusion Findings underline the strong influence of loss of spouse as well as dementia on institutionalization. This is relevant as the number of old people (a) living alone and (b) suffering from dementia is expected to increase rapidly in the next decades. Consequently, it is supposed that the demand for institutionalization among the elderly will increase considerably. Practitioners as well as policy makers should be aware of these upcoming challenges.

Abstract
BACKGROUND Lung cancer is one of the most common malignant neoplasms worldwide and has a high mortality rate. To enable individualized therapy regimens, a better understanding of the molecular tumor biology has still to be elucidated. The expression of the cell surface protein CD24 has already been claimed to be associated with shorter patient survival in non-small cell lung cancer (NSCLC), however, the prognostic value and applicability of CD24 immunostaining in paraffin embedded tissue specimens has been questioned due to the recent acknowledgement of restricted epitope specificity of the commonly used antibody SN3b. METHODS A cohort of 137 primary NSCLC cases was immunostained with a novel CD24 antibody (clone SWA11), which specifically recognizes the CD24 protein core and the resulting expression data were compared with expression profiles based on the monoclonal antibody SN3b. Furthermore, expression data were correlated to clinico-pathological parameters. Univariate and multivariate survival analyses were conducted with Kaplan Meier estimates and Cox regression, respectively. RESULTS CD24 positivity was found in 34 % resp. 21 % (SN3b) of NSCLC with a membranous and/or cytoplasmic staining pattern. Kaplan-Meier analyses revealed that membranous, but not cytoplasmic CD24 expression (clone SWA11) was associated with lympho-nodular spread and shorter overall survival times (both p < 0.05). CD24 expression established by SN3b antibodies did not reveal significant clinicopathological correlations with overall survival, neither for cytoplasmic nor membranous CD24 staining. CONCLUSIONS Membranous CD24 immunoreactivity, as detected with antibody clone SWA11 may serve as a prognostic factor for lymphonodular spread and poorer overall survival. Furthermore, these results corroborate the importance of a careful distinction between membranous and cytoplasmic localisation, if CD24 is to be considered as a potential prognostic biomarker.

Abstract
Type 2 diabetes mellitus (T2DM) is a risk factor of dementia. The effect of T2DM treatment quality on dementia risk, however, is unclear. 1,342 elderly individuals recruited via general practitioner registries (AgeCoDe cohort) were analyzed. This study analyzed the association between HbA1c level and the incidence of all-cause dementia (ACD) and of Alzheimer's disease dementia (referred to here as AD). HbA1c levels ≥6.5% were associated with 2.8-fold increased risk of incident ACD (p = 0.027) and for AD (p = 0.047). HbA1c levels ≥7% were associated with a five-fold increased risk of incident ACD (p = 0.001) and 4.7-fold increased risk of incident AD (p = 0.004). The T2DM diagnosis per se did not increase the risk of either ACD or AD. Higher levels of HbA1c are associated with increased risk of ACD and AD in an elderly population. T2DM diagnosis was not associated with increased risk if HbA1c levels were below 7%.

Abstract
OBJECTIVE Dementia is known to increase mortality, but the relative loss of life years and contributing factors are not well established. Thus, we aimed to investigate mortality in incident dementia from disease onset. METHOD Data were derived from the prospective longitudinal German AgeCoDe study. We used proportional hazards models to assess the impact of sociodemographic and health characteristics on mortality after dementia onset, Kaplan-Meier method for median survival times. RESULTS Of 3214 subjects at risk, 523 (16.3%) developed incident dementia during a 9-year follow-up period. Median survival time after onset was 3.2 years (95% CI = 2.8-3.7) at a mean age of 85.0 (SD = 4.0) years (≥2.6 life years lost compared with the general German population). Survival was shorter in older age, males other dementias than Alzheimer's, and in the absence of subjective memory complaints (SMC). CONCLUSION Our findings emphasize that dementia substantially shortens life expectancy. Future studies should further investigate the potential impact of SMC on mortality in dementia.

Abstract
BACKGROUND AND AIM We investigated the use of prescription and non-prescription (over-the-counter, OTC) analgesics and the associated risks in elderly patients with multiple morbidities. METHODS Pain medication use was evaluated from the baseline data (2008/2009) of the MultiCare cohort enrolling elderly patients with multiple morbidities who were treated by primary care physicians (trial registration: ISRCTN89818205). We considered opioids (N02A), other analgesics, and antipyretics (N02B) as well as nonsteroidal anti-inflammatory drugs (NSAIDs; M01A). OTC use, duplicate prescription, dosages, and interactions were examined for acetylsalicylic acid, diclofenac, (dex)ibuprofen, naproxen, and acetaminophen. RESULTS Of 3,189 patients with multiple morbidities aged 65-85 years, 1,170 patients reported to have taken at least one prescription or non-prescription analgesic within the last 3 months (36.7 %). Of these, 289 patients (24.7 % of 1,170) took at least one OTC analgesic. Duplicate prescription was observed in 86 cases; 15 of these cases took the analgesics regularly. In two cases, the maximum daily dose of diclofenac was exceeded due to duplicate prescription. In 235 cases, patients concurrently took a drug with a potentially clinically relevant interaction. In 43 cases (18.3 % of 235) an OTC analgesic, usually ibuprofen, was involved. DISCUSSION About one third of the elderly patients took analgesics regularly or as needed. Despite the relatively high use of OTC analgesics, the proportions of duplicate prescription, medication overdoses, and adverse interactions due to OTC products was low.

Abstract
Drugs that modify the risk of dementia in the elderly are of potential interest for dementia prevention. Proton pump inhibitors (PPIs) are widely used to reduce gastric acid production, but information on the risk of dementia is lacking. We assessed association between the use of PPIs and the risk of dementia in elderly people. Data were derived from a longitudinal, multicenter cohort study in elderly primary care patients, the German Study on Aging, Cognition and Dementia in Primary Care Patients (AgeCoDe), including 3,327 community-dwelling persons aged ≥ 75 years. From follow-up 1 to follow-up 4 (follow-up interval 18 months), we identified a total of 431 patients with incident any dementia, including 260 patients with Alzheimer's disease. We used time-dependent Cox regression to estimate hazard ratios of incident any dementia and Alzheimer's disease. Potential confounders included in the analysis comprised age, sex, education, the Apolipoprotein E4 (ApoE4) allele status, polypharmacy, and the comorbidities depression, diabetes, ischemic heart disease, and stroke. Patients receiving PPI medication had a significantly increased risk of any dementia [Hazard ratio (HR) 1.38, 95% confidence interval (CI) 1.04-1.83] and Alzheimer's disease (HR 1.44, 95% CI 1.01-2.06) compared with nonusers. Due to the major burden of dementia on public health and the lack of curative medication, this finding is of high interest to research on dementia and provides indication for dementia prevention.

Abstract
BACKGROUND Mean body weight gradually increases with age. Yet, little data exists on the prevalence of excess weight in populations aged 80 years or older. Moreover, little is known about predictors of overweight and obesity in old age. Thus, the purpose of this study was: To present data on the prevalence of excess weight in old age in Germany, to investigate predictors of excess weight in a cross-sectional approach and to examine factors affecting excess weight in a longitudinal approach. METHODS Subjects consisted of 1,882 individuals aged 79 years or older. The course of excess weight was observed over 3 years. Excess weight was defined as follows: Overweight (25 kg/m(2) ≤ BMI < 30 kg/m(2)) and obesity (BMI ≥ 30 kg/m(2)). We used fixed effects regressions to estimate effects of time dependent variables on BMI, and overweight or obesity, respectively. RESULTS The majority was overweight (40.0%) or obese (13.7%). Cross-sectional regressions revealed that BMI was positively associated with younger age, severe walking impairments and negatively associated with cognitive impairments. Excess weight was positively associated with younger age, elementary education, walking impairments and physical inactivity, while excess weight was negatively associated with cognitive impairment. Longitudinal regressions showed that age and severely impaired walking disabilities reduced BMI. The probability of transitions to excess weight decreased considerably with older age and occurrence of severe walking impairments (overweight). CONCLUSIONS Marked differences between predictors in cross- and longitudinal setting exist, underlining the complex nature of excess weight in old age.

Abstract
The aim of the study was to investigate the psychometric properties of a Short Form of the Mini-Mental State Examination (SMMSE) for the screening of dementia in older primary care patients. Data were obtained from a large longitudinal cohort study of initially nondemented individuals recruited via primary care chart registries and followed at 18-month intervals. Item and scale parameters for MMSE and SMMSE scores were analyzed and cross-validated for 2 follow-up assessments (n1 = 2,657 and n2 = 2,274). Binary logistic regression and receiver-operating-characteristic (ROC) curve analyses were conducted in order to assess diagnostic accuracy parameters for MMSE and SMMSE scores. Cross-sectional differentiation between dementia-free and dementia patients yielded moderate to good results for MMSE and SMMSE scores. With regard to most diagnostic accuracy parameters, SMMSE scores did not outperform the MMSE scores. The current study provides first evidence regarding the psychometric properties of the SMMSE score in a sample of older primary care patients. However, our findings do not confirm previous findings that the SMMSE is a more accurate screening instrument for dementia than the original MMSE. Further studies are needed in order to assess and to develop short, reliable and valid instruments for routine cognitive screening in clinical practice and primary care settings.

Abstract
Introduction In this article three research questions are addressed: (1) Is there an association between socioeconomic status (SES) and patient-reported outcomes in a cohort of multimorbid patients? (2) Does the association vary according to SES indicator used (income, education, occupational position)? (3) Can the association between SES and patient-reported outcomes (self-rated health, health-related quality of life and functional status) be (partly) explained by burden of disease? Methods Analyses are based on the MultiCare Cohort Study, a German multicentre, prospective, observational cohort study of multimorbid patients from general practice. We analysed baseline data and data from the first follow-up after 15 months (N = 2,729). To assess burden of disease we used the patients’ morbidity data from standardized general practitioner (GP) interviews based on a list of 46 groups of chronic conditions including the GP’s severity rating of each chronic condition ranging from marginal to very severe. Results In the cross-sectional analyses SES was significantly associated with the patient-reported outcomes at baseline. Associations with income were more consistent and stronger than with education and occupational position. Associations were partly explained (17% to 44%) by burden of disease. In the longitudinal analyses only income (but not education and occupational position) was significantly related to the patient-reported outcomes at follow-up. Associations between income and the outcomes were reduced by 18% to 27% after adjustment for burden of disease. Conclusions Results indicate social inequalities in self-rated health, functional status and health related quality of life among older multimorbid patients. As associations with education and occupational position were inconsistent, these inequalities were mainly due to income. Inequalities were partly explained by burden of disease. However, even among patients with a similar disease burden, those with a low income were worse off in terms of the three patient-reported outcomes under study.

Abstract
BACKGROUND Charcot osteoarthropathy of the hindfoot with considerable dislocation and instability represents a therapeutic dilemma. The treatment goal is a plantigrade, stable foot that is free of infection and ulceration with the ability to ambulate in special footwear. MATERIALS AND METHODS Over a period of 6 years, we performed 23 hindfoot fusions in 21 patients with manifest Charcot arthropathy with the help of a curved retrograde nail (HAN). All patients suffered from insulin-dependent diabetes mellitus with polyneuropathy; 12 patients had additional peripheral vasculopathy. An average of 3.5 previous surgeries had been performed prior to hindfoot fusion. RESULTS Complete tibiotalocalcaneal fusion was obtained in 16 of 21 patients (76 %). Of these 21 patients, 18 (86 %) were followed clinically and radiologically for an average of 2 years. Overall, 16 patients (89 %) reported a substantial subjective improvement compared to the preoperative state. Hardware failure occurred in 7 cases (30 %) that could be brought to consolidation with exchange of the locking bolts or the complete nail. In 5 cases (22 %), a postoperative hematoma had to be removed and in 8 cases (35 %) wound edge necrosis was treated with local wound care. In 2 cases (9 %), a secondary or reactivated osteitis occurred that finally required below knee amputation. CONCLUSION Tibiotalocalcaneal fusion with a curved retrograde intramedullary nail (HAN) is an effective treatment option in highly unstable and deforming Charcot osteoarthropathy of the hindfoot. It is an alternative to external or other internal fixation methods and helps to avoid below knee amputation in more than 90 % of cases.

Abstract
Background Social relations and depressive symptoms are intertwined. They both predict subsequent dementia, but only few studies on the association between social life aspects and subsequent dementia exist. Methods The risk of subsequent dementia was estimated over 2 follow-up assessments, each 18 months apart, depending on leisure activity, social support (general scale and the 3 factors emotional support, practical support, and social integration), and depressive symptoms, using proportional hazard models in a cohort of elderly patients (n = 2,300, with a mean age of 82.45 years) recruited for the study by their general practitioners. Results Higher depressive symptoms and lower cognitive and physical activity were associated with an increased risk of subsequent all-cause dementia and Alzheimer's dementia (AD). While neither social engagement nor the general social support scale was associated with subsequent dementia, a higher level of social integration was associated with a lower dementia risk. In combined models, the results for activity variables remained similar, but the strength of the association between depressive symptoms and the subsequent risk of dementia decreased, and the association with social integration disappeared. Conclusions Depressive symptoms increased and activity variables decreased the risk of subsequent dementia; however, activity variables, namely cognitive and physical activity, partly mediated the effect of depressive symptoms on the subsequent risk of all-cause dementia and AD. In many cases, social support was not associated with a risk of subsequent dementia.

Abstract
Implementation of ABO-incompatible (ABOi) pediatric heart transplantation has contributed to significant reduction in the mortality of infants on the waiting list, without increasing the risk of rejection. This has been attributed to the immature and therefore not fully competent immune system in this population group, which results in lower production of isohemagglutinins compared to older children and adults. Serial evaluations of isohemagglutinin titers in infants revealed cases with absence of donor specific anti-blood group antibodies. However, it is currently unknown whether continuous exposure to donor antigens is necessary to prevent formation of donor specific isohemagglutinins (DSI) in recipients. We are reporting a case of an infant who underwent ABOi heart transplantation, with no evidence of DSI even 4 years after ABO-compatible retransplantation. Hence, temporary exposure to donor antigens in infants may contribute to permanent absence of donor specific anti-blood group antibodies, suggesting the possibility of induced permanent B cell tolerance.

Abstract
A 74-year-old multimorbid man was admitted with fever of unknown origin. Over time the fever ceased spontaneously. The patient developed signs of a right heart failure without evidence of a primarily cardiac pathogenesis and died of acute right heart failure. Miliary tuberculosis that had lead to pulmonary artery hypertension was diagnosed at autopsy.

Abstract
BACKGROUND For general practioners (GP) the treatment of patients suffering from multimorbidity is an everyday challenge. For these patients guidelines which each focus on a specific chronic disease cannot be applied comprehensively and equally; therefore, it is necessary to prioritize. OBJECTIVE Given this situation the study aimed at analyzing how GPs and patients deal with this challenge and what their priorities are. MATERIAL AND METHODS Narrative interviews were conducted with 9 GPs and 19 of their multimorbid patients. The data were analyzed by means of content analysis. RESULTS The majority of interviewed patients felt well or very well cared for by their GPs; however, GPs and multimorbid patients often had relatively different priorities. Whereas GPs mostly focused on the management of diseases that could lead to life-threatening situations, patients put an emphasis on maintaining autonomy and a social life. CONCLUSION The results of this study suggest that there is room for development in the way GPs and multimorbid patients communicate with each other, particularly as far as shared priority setting is concerned.

Abstract
At the Paul Scherrer Institute, the new SwissFEL Free Electron Laser facility is currently in the design phase. It is foreseen to accelerate electrons up to a maximum energy of 7 GeV with a pulsed time structure. An injector test facility is operated at a maximum energy of 300 MeV and serves as the principal test and demonstration plant for the SwissFEL project. Secondary radiation is created in unavoidable interactions of the primary beam with beamline components. The resulting ambient dose-equivalent rate due to neutrons was measured along the beamline with different commercially available survey instruments. The present study compares the readings of these neutron detectors (one of them is specifically designed for measurements in pulsed fields). The experiments were carried out in both, a normal and a diagnostic mode of operation of the injector.

Abstract
OBJECTIVES To establish the diagnostic accuracy of the Total Score of the Consortium to Establish a Registry for Alzheimer's Disease neuropsychological assessment battery (CERAD-NP) both for cross-sectional discrimination of Alzheimer disease (AD) dementia and short-term prediction of incident AD dementia. DESIGN Longitudinal cohort study with two assessments at a 1.5-year interval. SETTING Primary care sample randomly recruited via medical record registries. PARTICIPANTS As part of the German Study on Ageing, Cognition, and Dementia (AgeCoDe), a sample of elderly individuals (N = 1,606; mean age: 84 years) was assessed. MEASUREMENTS Subjects were assessed with the CERAD-NP and followed up for 18 months (97.6% follow-up rate). Logistic regression and receiver-operating-characteristic (ROC) curve analysis were used to compare the diagnostic accuracy of the CERAD-NP Total Score (CTS) with that of single CERAD-NP scores and the Mini-Mental-State-Examination (MMSE) score. RESULTS ROC curve analysis resulted in excellent (area under the curve [AUC]: 0.97) cross-sectional discrimination between non-AD and AD dementia subjects. Prediction of incident AD dementia with the CTS was also very good (AUC: 0.89), and was significantly better than prediction based on the MMSE. CONCLUSIONS The cross-sectional results confirm that the CTS is a highly accurate diagnostic tool for detecting AD dementia in elderly primary care patients. In addition, we provide evidence that the CTS is also accurate for the prediction of incident AD dementia. These findings further support the validity of the CTS as an index of overall cognitive functioning for detection and prediction of AD dementia.

Abstract
BACKGROUND The objective of the study was to compare General Practitioners׳ (GPs) diagnosis of depression and depression diagnosis according to Geriatric Depression Scale (GDS) and to identify potential factors associated with both depression diagnosis methods. METHODS The data were derived from the baseline wave of the German MultiCare1 study, which is a multicentre, prospective, observational cohort study of 3177 multimorbid patients aged 65+ randomly selected from 158 GP practices. Data were collected in GP interviews and comprehensive patient interviews. Depressive symptoms were assessed with a short version of the Geriatric Depression Scale (15 items, cut-off 6). Cohen׳s kappa was used to assess agreement of GP and GDS diagnoses. To identify factors that might have influenced GP and GDS diagnoses of depression, binary logistic regression analyses were performed. RESULTS Depressive symptoms according to GDS were diagnosed in 12.6% of the multimorbid subjects, while 17.8% of the patients received a depression diagnosis by their GP. The agreement between general practitioners and GDS diagnosis was poor. To summarize we find that GPs and the GDS have different perspectives on depression. To GPs somatic and psychological comorbid conditions carry weight when diagnosing depression, while cognitive impairment in form of low verbal fluency, pain and comorbid somatic conditions are relevant for a depression diagnosis by GDS. CONCLUSIONS Each depression diagnosing method is influenced by different variables and therefore, has advantages and limitations. Possibly, the application of both, GP and GDS diagnoses of depression, could provide valuable support in combining the different perspectives of depression and contribute to a comprehensive view on multimorbid elderly in primary care setting.

Abstract
Background In primary care, patients with multiple chronic conditions are the rule rather than the exception. The Chronic Care Model (CCM) is an evidence-based framework for improving chronic illness care, but little is known about the extent to which it has been implemented in routine primary care. The aim of this study was to describe how multimorbid older patients assess the routine chronic care they receive in primary care practices in Germany, and to explore the extent to which factors at both the practice and patient level determine their views. Methods This cross-sectional study used baseline data from an observational cohort study involving 158 general practitioners (GP) and 3189 multimorbid patients. Standardized questionnaires were employed to collect data, and the Patient Assessment of Chronic Illness Care (PACIC) questionnaire used to assess the quality of care received. Multilevel hierarchical modeling was used to identify any existing association between the dependent variable, PACIC, and independent variables at the patient level (socio-economic factors, weighted count of chronic conditions, instrumental activities of daily living, health-related quality of life, graded chronic pain, no. of contacts with GP, existence of a disease management program (DMP) disease, self-efficacy, and social support) and the practice level (age and sex of GP, years in current practice, size and type of practice). Results The overall mean PACIC score was 2.4 (SD 0.8), with the mean subscale scores ranging from 2.0 (SD 1.0, subscale goal setting/tailoring) to 3.5 (SD 0.7, delivery system design). At the patient level, higher PACIC scores were associated with a DMP disease, more frequent GP contacts, higher social support, and higher autonomy of past occupation. At the practice level, solo practices were associated with higher PACIC values than other types of practice. Conclusions This study shows that from the perspective of multimorbid patients receiving care in German primary care practices, the implementation of structured care and counseling could be improved, particularly by helping patients set specific goals, coordinating care, and arranging follow-up contacts. Studies evaluating chronic care should take into consideration that a patient’s assessment is associated not only with practice-level factors, but also with individual, patient-level factors.

Abstract
BACKGROUND In the revised version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) the Mood Disorder Workgroup for DSM-V the bereavement exclusion criterion for the diagnosis of major depression has been eliminated. AIM To investigate the impact of bereavement on the incidence of depression and depressive symptoms in the elderly. METHOD Participants over 75 years from the longitudinal German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe) that were still married at baseline were investigated (n=1,193). Data from four follow-ups (time frame: 6 years) were investigated. The response rate at baseline was 50.3%. Three clinical endpoints were analyzed: depressive symptoms according to Geriatric Depression Scale (1) GDS≥6, (2) GDS≥10, and (3) Major Depression (MD). The effect of loss was investigated using random-effects regression models. RESULTS Experiencing a loss of spouse was predictive of a higher incidence in GDS≥6 (OR 4.52, 95% CI 2.6-7.9) and 10 (OR 5.59, 95% CI 1.8-17.0) even after adjusting for age, gender, impairment at baseline, and GDS score at baseline. Associations with MD were not significant (OR 1.77, 96% CI 0.9-3.5). CONCLUSIONS Older adults experiencing the loss of their spouse are more likely to display elevated levels of depressive symptoms, that may reach a concerning level of severity.

Abstract
To gain insight into the adaptive mechanisms to tripedal locomotion and increase understanding of the biomechanical consequences of limb amputation, this study investigated kinetic and temporal gait parameters in dogs before and after the loss of a hindlimb was simulated. Nine clinically sound Beagle dogs trotted on an instrumented treadmill and the ground reaction forces as well as the footfall patterns were compared between quadrupedal and tripedal locomotion. Stride and stance durations decreased significantly in all limbs when the dogs ambulated tripedally, while relative stance duration increased. Both vertical and craniocaudal forces were significantly different in the remaining hindlimb. In the forelimbs, propulsive force increased in the contralateral and decreased in the ipsilateral limb, while the vertical forces were unchanged (except for mean force in the contralateral limb). Bodyweight was shifted to the contralateral and cranial body side so that each limb bore ~33% of the dog's bodyweight. The observed changes in the craniocaudal forces and the vertical impulse ratio between the fore- and hindlimbs suggest that a nose-up pitching moment occurs during the affected limb pair's functional step. To regain pitch balance for a given stride cycle, a nose-down pitching moment is exerted when the intact limb pair supports the body. These kinetic changes indicate a compensatory mechanism in which the unaffected diagonal limb pair is involved. Therefore, the intact support pair of limbs should be monitored closely in canine hindlimb amputees.

Abstract
BACKGROUND As physical activity may modify the effect of the apolipoprotein E (APOE) ε4 allele on the risk of dementia and Alzheimer's disease (AD) dementia, we tested for such a gene-environment interaction in a sample of general practice patients aged ⩾75 years. METHOD Data were derived from follow-up waves I-IV of the longitudinal German study on Ageing, Cognition and Dementia in Primary Care Patients (AgeCoDe). The Kaplan-Meier survival method was used to estimate dementia- and AD-free survival times. Multivariable Cox regression was used to assess individual associations of APOE ε4 and physical activity with risk for dementia and AD, controlling for covariates. We tested for gene-environment interaction by calculating three indices of additive interaction. RESULTS Among the randomly selected sample of 6619 patients, 3327 (50.3%) individuals participated in the study at baseline and 2810 (42.5%) at follow-up I. Of the 2492 patients without dementia included at follow-up I, 278 developed dementia (184 AD) over the subsequent follow-up interval of 4.5 years. The presence of the APOE ε4 allele significantly increased and higher physical activity significantly decreased risk for dementia and AD. The co-presence of APOE ε4 with low physical activity was associated with higher risk for dementia and AD and shorter dementia- and AD-free survival time than the presence of APOE ε4 or low physical activity alone. Indices of interaction indicated no significant interaction between low physical activity and the APOE ε4 allele for general dementia risk, but a possible additive interaction for AD risk. CONCLUSIONS Physical activity even in late life may be effective in reducing conversion to dementia and AD or in delaying the onset of clinical manifestations. APOE ε4 carriers may particularly benefit from increasing physical activity with regard to their risk for AD.

Abstract
Objective The objective of this study was to describe and analyze the effects of depression on health care utilization and costs in a sample of multimorbid elderly patients. Method This cross-sectional analysis used data of a prospective cohort study, consisting of 1,050 randomly selected multimorbid primary care patients aged 65 to 85 years. Depression was defined as a score of six points or more on the Geriatric Depression Scale (GDS-15). Subjects passed a geriatric assessment, including a questionnaire for health care utilization. The impact of depression on health care costs was analyzed using multiple linear regression models. A societal perspective was adopted. Results Prevalence of depression was 10.7%. Mean total costs per six-month period were €8,144 (95% CI: €6,199-€10,090) in patients with depression as compared to €3,137 (95% CI: €2,735-€3,538; p<0.001) in patients without depression. The positive association between depression and total costs persisted after controlling for socio-economic variables, functional status and level of multimorbidity. In particular, multiple regression analyses showed a significant positive association between depression and pharmaceutical costs. Conclusion Among multimorbid elderly patients, depression was associated with significantly higher health care utilization and costs. The effect of depression on costs was even greater than reported by previous studies conducted in less morbid patients.

Abstract
PURPOSE The concept of mild cognitive impairment (MCI) has recently been introduced into the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) as mild neurocognitive disorder, making it a formal diagnosis. We investigated the prognostic value of such a diagnosis and analyzed the determinants of the future course of MCI in the AgeCoDe study (German Study on Ageing, Cognition, and Dementia in Primary Care Patients). METHODS We recruited 357 patients with MCI aged 75 years or older from primary care practices and conducted follow-up with interviews for 3 years. Depending on the course of impairment over time, the patients were retrospectively split into 4 groups representing remittent, fluctuating, stable, and progressive courses of MCI. We performed ordinal logistic regression analysis and classification and regression tree (CART) analysis. RESULTS Overall, 41.5% of the patients had remission of symptoms with normal cognitive function 1.5 and 3 years later, 21.3% showed a fluctuating course, 14.8% had stable symptoms, and 22.4% had progression to dementia. Patients were at higher risk for advancing from one course to the next along this spectrum if they had symptoms of depression, impairment in more than 1 cognitive domain, or more severe cognitive impairment, or were older. The result on a test of the ability to learn and reproduce new material 10 minutes later was the best indicator at baseline for differentiating between remittent and progressive MCI. Symptoms of depression modified the prognosis. CONCLUSIONS In primary care, about one-quarter of patients with MCI have progression to dementia within the next 3 years. Assessments of memory function and depressive symptoms are helpful in predicting a progressive vs a remittent course. When transferring the concept of MCI into clinical diagnostic algorithms (eg, DSM-5), however, we should not forget that three-quarters of patients with MCI stayed cognitively stable or even improved within 3 years. They should not be alarmed unnecessarily by receiving such a diagnosis.

Abstract
BACKGROUND Multimorbidity is a common phenomenon in primary care. Until now, no clinical guidelines for multimorbidity exist. For the development of these guidelines, it is necessary to know whether or not patients are aware of their diseases and to what extent they agree with their doctor. The objectives of this paper are to analyze the agreement of self-reported and general practitioner-reported chronic conditions among multimorbid patients in primary care, and to discover which patient characteristics are associated with positive agreement. METHODS The MultiCare Cohort Study is a multicenter, prospective, observational cohort study of 3,189 multimorbid patients, ages 65 to 85. Data was collected in personal interviews with patients and GPs. The prevalence proportions for 32 diagnosis groups, kappa coefficients and proportions of specific agreement were calculated in order to examine the agreement of patient self-reported and general practitioner-reported chronic conditions. Logistic regression models were calculated to analyze which patient characteristics can be associated with positive agreement. RESULTS We identified four chronic conditions with good agreement (e.g. diabetes mellitus κ = 0.80;PA = 0,87), seven with moderate agreement (e.g. cerebral ischemia/chronic stroke κ = 0.55;PA = 0.60), seventeen with fair agreement (e.g. cardiac insufficiency κ = 0.24;PA = 0.36) and four with poor agreement (e.g. gynecological problems κ = 0.05;PA = 0.10).Factors associated with positive agreement concerning different chronic diseases were sex, age, education, income, disease count, depression, EQ VAS score and nursing care dependency. For example: Women had higher odds ratios for positive agreement with their GP regarding osteoporosis (OR = 7.16). The odds ratios for positive agreement increase with increasing multimorbidity in almost all of the observed chronic conditions (OR = 1.22-2.41). CONCLUSIONS For multimorbidity research, the knowledge of diseases with high disagreement levels between the patients' perceived illnesses and their physicians' reports is important. The analysis shows that different patient characteristics have an impact on the agreement. Findings from this study should be included in the development of clinical guidelines for multimorbidity aiming to optimize health care. Further research is needed to identify more reasons for disagreement and their consequences in health care. TRIAL REGISTRATION ISRCTN89818205.

Abstract
BACKGROUND Elderly people are often burdened by several diseases. This accounts for a higher medication intake and increases the risk of adverse drug events. To minimize this risk, several lists (Beers, PRISCUS) have been published of drugs that elderly patients should not take. We present a longitudinal analysis of the use of potentially inappropriate medication (PIM) over a period 4.5 years in a cohort of patients aged 75 years or more. METHODS Data were collected from the prospective, multicenter, observational study "German Study on Ageing, Cognition and Dementia in Primary Care Patients (AgeCoDe)," initially enrolling 3,327 patients. We investigated the prevalence of PIM by checking medications during visits to patients' homes. Furthermore, we analyzed the use of individual PIM agents over time. RESULTS At baseline, we found a PIM prevalence of 29 % according to the PRISCUS list, which decreased to 25.0 % 4.5 years later (χ(2): 7.87, p = 0.004). The Beers list yielded a prevalence of 21 % at baseline, decreasing after 4.5 years to 17.1 % (χ(2): 10.77, p = 0.000). A time-dependent multilevel model confirmed these results. Older age, depression, and the use of numerous prescribed agents are independent risk factors for using a PRISCUS-PIM. CONCLUSION Our results seem to support a trend toward a more rational drug therapy because fewer patients were prescribed PIM. Thus, for the individual patient, the risk of adverse effects and side effects is reduced as are the costs of these effects.

Abstract
Background With increasing life expectancy the number of people affected by multimorbidity rises. Knowledge of factors associated with health-related quality of life in multimorbid people is scarce. We aimed to identify the factors that are associated with self-rated health (SRH) in aged multimorbid primary care patients. Methods Cross-sectional study with 3,189 multimorbid primary care patients aged from 65 to 85 years recruited in 158 general practices in 8 study centers in Germany. Information about morbidity, risk factors, resources, functional status and socio-economic data were collected in face-to-face interviews. Factors associated with SRH were identified by multivariable regression analyses. Results Depression, somatization, pain, limitations of instrumental activities (iADL), age, distress and Body Mass Index (BMI) were inversely related with SRH. Higher levels of physical activity, income and self-efficacy expectation had a positive association with SRH. The only chronic diseases remaining in the final model were Parkinson’s disease and neuropathies. The final model accounted for 35% variance of SRH. Separate analyses for men and women detected some similarities; however, gender specific variation existed for several factors. Conclusion In multimorbid patients symptoms and consequences of diseases such as pain and activity limitations, as well as depression, seem to be far stronger associated with SRH than the diseases themselves. High income and self-efficacy expectation are independently associated with better SRH and high BMI and age with low SRH. Trial registration MultiCare Cohort study registration:ISRCTN89818205.

Abstract
OBJECTIVE Progression from cognitive impairment (CI) to dementia is predicted by several factors, but their relative importance and interaction are unclear. METHOD We investigated numerous such factors in the AgeCoDe study, a longitudinal study of general practice patients aged 75+. We used recursive partitioning analysis (RPA) to identify hierarchical patterns of baseline covariates that predicted dementia-free survival. RESULTS Among 784 non-demented patients with CI, 157 (20.0%) developed dementia over a follow-up interval of 4.5 years. RPA showed that more severe cognitive compromise, revealed by a Mini-Mental State Examination (MMSE) score < 27.47, was the strongest predictor of imminent dementia. Dementia-free survival time was shortest (mean 2.4 years) in such low-scoring patients who also had impaired instrumental activities of daily living (iADL) and subjective memory impairment with related worry (SMI-w). Patients with identical characteristics but without SMI-w had an estimated mean dementia-free survival time of 3.8 years, which was still shorter than in patients who had subthreshold MMSE scores but intact iADL (4.2-5.2 years). CONCLUSION Hierarchical patterns of readily available covariates can predict dementia-free survival in older general practice patients with CI. Although less widely appreciated than other variables, iADL impairment appears to be an especially noteworthy predictor of progression to dementia.

Abstract
BACKGROUND Whether late-onset depression is a risk factor for or a prodrome of dementia remains unclear. We investigated the impact of depressive symptoms and early- v. late-onset depression on subsequent dementia in a cohort of elderly general-practitioner patients (n = 2663, mean age = 81.2 years). METHOD Risk for subsequent dementia was estimated over three follow-ups (each 18 months apart) depending on history of depression, particularly age of depression onset, and current depressive symptoms using proportional hazard models. We also examined the additive prediction of incident dementia by depression beyond cognitive impairment. RESULTS An increase of dementia risk for higher age cut-offs of late-onset depression was found. In analyses controlling for age, sex, education, and apolipoprotein E4 genotype, we found that very late-onset depression (aged ≥ 70 years) and current depressive symptoms separately predicted all-cause dementia. Combined very late-onset depression with current depressive symptoms was specifically predictive for later Alzheimer's disease (AD; adjusted hazard ratio 5.48, 95% confidence interval 2.41-12.46, p < 0.001). This association was still significant after controlling for cognitive measures, but further analyses suggested that it was mediated by subjective memory impairment with worries. CONCLUSIONS Depression might be a prodrome of AD but not of dementia of other aetiology as very late-onset depression in combination with current depressive symptoms, possibly emerging as a consequence of subjectively perceived worrisome cognitive deterioration, was most predictive. As depression parameters and subjective memory impairment predicted AD independently of objective cognition, clinicians should take this into account.

Abstract
OBJECTIVE To analyse predictors of costs in dementia from a societal perspective in a longitudinal setting. METHOD Healthcare resource use and costs were assessed retrospectively using a questionnaire in four waves at 6-month intervals in a sample of dementia patients (N = 175). Sociodemographic data, dementia severity and comorbidity at baseline, cognitive impairment and impairment in basic and instrumental activities of daily living were also recorded. Linear mixed regression models with random intercepts for individuals were used to analyse predictors of total and sector-specific costs. RESULTS Impairment in activities of daily living significantly predicted total costs in dementia patients, with associations between basic activities of daily living and formal care costs on the one and instrumental activities of daily living and informal care costs on the other hand. Nursing home residence was associated with lower total costs than residence in the community. There was no effect of cognition on total or sector-specific costs. CONCLUSION Cognitive deficits in dementia are associated with costs only via their effect on the patients' capacity for activities of daily living. Transition into a nursing home may reduce total costs from a societal perspective, owing to the fact that a high amount of informal care required by severely demented patients prior to transition into a nursing home may cause higher costs than inpatient nursing care.

Abstract
Background Multimorbidity has a negative impact on health-related quality of life (HRQL). Previous studies included only a limited number of conditions. In this study, we analyse the impact of a large number of conditions on HRQL in multimorbid patients without preselecting particular diseases. We also explore the effects of these conditions on the specific dimensions of HRQL. Materials and Methods This analysis is based on a multicenter, prospective cohort study of 3189 multimorbid primary care patients aged 65 to 85. The impact of 45 conditions on HRQL was analysed. The severity of the conditions was rated. The EQ-5D, consisting of 5 dimensions and a visual-analogue-scale (EQ VAS), was employed. Data were analysed using multiple ordinary least squares and multiple logistic regressions. Multimorbidity measured by a weighted count score was significantly associated with lower overall HRQL (EQ VAS), b = −1.02 (SE: 0.06). Parkinson’s disease had the most pronounced negative effect on overall HRQL (EQ VAS), b = −12.29 (SE: 2.18), followed by rheumatism, depression, and obesity. With regard to the individual EQ-5D dimensions, depression (OR = 1.39 to 3.3) and obesity (OR = 1.44 to 1.95) affected all five dimensions of the EQ-5D negatively except for the dimension anxiety/depression. Obesity had a positive effect on this dimension, OR = 0.78 (SE: 0.07). The dimensions “self-care”, OR = 4.52 (SE: 1.37) and “usual activities”, OR = 3.59 (SE: 1.0), were most strongly affected by Parkinson’s disease. As a limitation our sample may only represent patients with at most moderate disease severity. Conclusions The overall HRQL of multimorbid patients decreases with an increasing count and severity of conditions. Parkinson’s disease, depression and obesity have the strongest impact on HRQL. Further studies should address the impact of disease combinations which require very large sample sizes as well as advanced statistical methods.

Abstract
BACKGROUND To analyze the impact of multimorbidity (MM) on health care costs taking into account data heterogeneity. METHODS Data come from a multicenter prospective cohort study of 1,050 randomly selected primary care patients aged 65 to 85 years suffering from MM in Germany. MM was defined as co-occurrence of ≥3 conditions from a list of 29 chronic diseases. A conditional inference tree (CTREE) algorithm was used to detect the underlying structure and most influential variables on costs of inpatient care, outpatient care, medications as well as formal and informal nursing care. RESULTS Irrespective of the number and combination of co-morbidities, a limited number of factors influential on costs were detected. Parkinson's disease (PD) and cardiac insufficiency (CI) were the most influential variables for total costs. Compared to patients not suffering from any of the two conditions, PD increases predicted mean total costs 3.5-fold to approximately € 11,000 per 6 months, and CI two-fold to approximately € 6,100. The high total costs of PD are largely due to costs of nursing care. Costs of inpatient care were significantly influenced by cerebral ischemia/chronic stroke, whereas medication costs were associated with COPD, insomnia, PD and Diabetes. Except for costs of nursing care, socio-demographic variables did not significantly influence costs. CONCLUSIONS Irrespective of any combination and number of co-occurring diseases, PD and CI appear to be most influential on total health care costs in elderly patients with MM, and only a limited number of factors significantly influenced cost.

Abstract
OBJECTIVE To compare radiation exposure doses and clinical and radiological outcomes between percutaneous pedicular screwing (closed reduction internal fixation [CRIF]) and classical open reduction internal fixation (ORIF) in lumbar spine fracture without neurologic deficit. MATERIALS AND METHODS Sixty patients (mean age, 42.5 years) were divided into two treatment groups: (Percutaneous) CRIF versus (traditional) ORIF. Screw position and anatomic vertebral reconstruction were checked on routine control X-ray and postoperative CT scan. Study parameters comprised: surgery time, radiation exposure time, radiation dose level for X-ray (DAP) and for CT (DLP),blood loss, length of hospital stay and postoperative pain (VAS). RESULTS At a mean 25.5 months' follow-up,there were no significant inter-group differences on the epidemiological parameters: age, gender, fracture level, fracture type on the Magerl classification, preoperative local vertebral kyphosis angle, or fracture-to-surgery interval. Effective radiation dose was 3-fold higher in CRIF than in ORIF, but 6-fold lower than for the postoperative CT scan. Postoperative pain on VAS was significantly lower after CRIF, allowing earlier gait resumption and return to work and daily activity. There were no significant differences in length of hospital stay, patient satisfaction, screw malpositioning or postoperative or end-of-follow-up kyphosis angle. CONCLUSION Percutaneous surgery provided clinical and radiological outcomes strictly comparable to those of open surgery, but with a higher effective radiation exposure dose, including for the medical team and especially for the surgeon. This higher exposure dose, however, is to be relativized by comparison to that of the postoperative CT scan, which involved a much higher exposure dose for the patient. LEVEL OF EVIDENCE Level IV. Retrospective study.

Abstract
OBJECTIVE We investigated the degree of comparability of the prevalence of chronic diseases and disease combinations in the elderly in two databases comparable with regard to diseases included, sex and age of the patients (65-85 years), and cutoff score for case definition. STUDY DESIGN AND SETTING One study is based on chart-supported interviews with the primary care physicians within a cohort study of 3,189 multimorbid elderly patients. The second study analyzed claims data from ambulatory care delivered to the multimorbid members of one German Health Insurance (n = 70,031). Multimorbidity was defined by the presence of three or more chronic conditions from an identical list of 46 diseases. RESULTS The difference of the median number of chronic conditions was 1 (mean 6.7 vs. 5.7). The prevalences of individual conditions were approximately one-third lower in the claims data, but the relative rank order corresponded well between the two databases. These relatively small prevalence differences cumulate when combinations of chronic conditions are investigated, for example, the prevalence differences between the two databases increased to nearly 100% for triadic combinations and nearly 170% for quartets. CONCLUSION The study shows that conclusions regarding the prevalence of combinations of diseases should be drawn with caution when based on a single database.

BACKGROUND Social integration seems to be associated with depression in late life. But the measurement of social integration still lacks a strong consensus. To date in most studies the different domains of social integration have been examined separately. AIMS In order to improve comparability among studies, we used the social integration index (SII), which covers all domains of social integration, to examine the association of social integration and depression in non-demented primary care patients aged 75 years and older. METHOD Data were derived from the longitudinal German study on Aging, Cognition and Dementia in primary care patients. Included in the cross-sectional survey were 1028 non-demented subjects aged 75 years and older. The GDS-15 Geriatric Depression Scale was used to measure depression with a threshold of ≥6. Associations of the SII and further potential risk factors and depression were analysed using multivariate logistic regression models. RESULTS The SII was significantly associated with depression in the elderly. After full adjustment for all variables, odds of depression were significantly higher for lower levels of the SII, having a care level, impaired vision and mobility and subjective memory complaints. CONCLUSION Because the social integration index covers several aspects of social integration, the results seem to be more significant than considering only one of these domains alone. Further research is needed to prove the practicability of the social integration index and to supply the literature with consistent results regarding the association of social integration and depression. Elderly with depression could benefit from increased social networks and enhanced social integration, which points to the development of social programs and social policies that maximize the engagement of older adults in social activities and volunteer roles.

Abstract
BACKGROUND/AIMS In the past few decades, a number of studies investigated risk factors of nursing home placement (NHP) in dementia patients. The aim of the study was to investigate risk factors of NHP in incident dementia cases, considering characteristics at the time of the dementia diagnosis. METHODS 254 incident dementia cases from a German general practice sample aged 75 years and older which were assessed every 1.5 years over 4 waves were included. A Cox proportional hazard regression model was used to determine predictors of NHP. Kaplan-Meier survival curves were used to evaluate the time until NHP. RESULTS Of the 254 incident dementia cases, 77 (30%) were institutionalised over the study course. The mean time until NHP was 4.1 years. Significant characteristics of NHP at the time of the dementia diagnosis were marital status (being single or widowed), higher severity of cognitive impairment and mobility impairment. CONCLUSION Marital status seems to play a decisive role in NHP. Early initiation of support of sufferers may ensure remaining in the familiar surroundings as long as possible.
