Abstract
INTRODUCTION Differences between women and men matter in the prevalence and risk factors of dementia. We aimed to examine potential sex differences regarding the effectiveness by running a secondary analysis of the AgeWell.de trial, a cluster-randomized multicenter multi-domain lifestyle intervention to reduce cognitive decline. METHODS Intention-to-treat analyses of women (n=433) and men (n=386) aged 60 to 77 years were used for models including interactions between intervention group allocation and sex followed by subgroup analysis stratified by sex on primary and secondary outcomes. Further, the same procedure was repeated for age groups (60-69 vs. 70-77) within sex-specific subgroups to assess the effectiveness in different age groups. TRIAL REGISTRATION German Clinical Trials Register (ref. number: DRKS00013555). RESULTS No differences were found between women and men in the effectiveness of the intervention on cognitive performance. However, women benefitted from the intervention regarding depressive symptoms while men did not. Health-related quality of life was enhanced for younger intervention participants (60-69 years) in both women and men. CONCLUSION The AgeWell.de intervention was able to improve depressive symptoms in women and health-related quality of life in younger participants. Female participants between 60 and 69 years benefited the most. Results support the need of better individually targeted lifestyle interventions for older adults.

Development of a shared decision-making intervention to improve drug safety and to reduce polypharmacy in frail elderly patients living at home. PEC INNOVATION 2022; 1:100032. [PMID: 37213749 PMCID: PMC10194292 DOI: 10.1016/j.pecinn.2022.100032] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 02/03/2022] [Accepted: 03/19/2022] [Indexed: 05/23/2023]
Abstract
Objectives For patients with geriatric frailty, reducing inappropriate medication is an important goal to improve patient safety in primary care. GP-side barriers include knowledge gaps, legal concerns, and lack of communication between the actors involved. The aim was to develop a multi-faceted intervention to facilitate deprescribing and shared prioritisation among frail elderlies with polypharmacy living at home. Methods Mixed methods study including: 1) scoping review on family conferences, expert panels; 2) group discussions with GPs, mapping of needs and challenges in Primary Care; 3) workshops and expert interviews with GPs, patient advocates, researchers as a basis for a theoretical intervention model; 4) piloting. Results A major challenge for GPs is to conduct a productive discussion with patients and family cares on deprescribing and drug safety. A guideline for a structured family conference with a medication check and geriatric assessment was developed and proved to be feasible in the pilot study. Conclusion The intervention developed to facilitate deprescribing and shared prioritisation of drug therapy based on family conferences seems suitable to be tested in a subsequent cRCT. Innovation Adapting family conferences to primary care for frail patients with polypharmacy.

The interplay of chronic stress and genetic traits discriminates between patients suffering from multisomatoform disorder with pain as the leading symptom and matched controls. J Affect Disord 2022; 308:466-472. [PMID: 35460735 DOI: 10.1016/j.jad.2022.04.094] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Revised: 04/05/2022] [Accepted: 04/13/2022] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Somatoform disorders and functional somatic syndromes (FSS) with symptoms that are not sufficiently explained by physical or technical examination are among the most challenging underlying causes. Many different somatoform disorders and FSS have overlapping symptoms, often with pain as the most prevalent one, leading to a high burden of disease. The concept of multisomatoform disorder (MSD) has been developed to acknowledge that fact. We analyzed a group of 151 patients and 149 matched controls to identify interactions of genetic and environmental factors with a possible influence on the development of MSD. DESIGN In a retrospective case-control study, we performed a statistical analysis on 151 patients and 149 matched controls using logistic regression and a Classification and Regression Tree (CART) analysis. RESULTS The logistic regression analysis of genes and environmental factors demonstrated significant differences in the results of the Trier Inventory of Chronic Stress (TICS) questionnaire, the single nucleotide polymorphism rs1800955 of the dopamine receptor D4 and the single nucleotide polymorphism rs4818 of the enzyme catechol-O-methyltransferase between patients with MSD and healthy controls. The resulting decision tree of the CART analysis determined that the TICS questionnaire was able to differentiate patients and controls most accurately, followed by certain genotypes of the 5-hydroxytryptamine receptor 2A and a single nucleotide polymorphism of the enzyme catechol-O-methyltransferase. CONCLUSIONS The results of the statistical analysis identified a gene-environmental interaction possibly leading to MSD. The resulting identifiers could be used as a reference to inform diagnostic algorithms to easier identify patients suffering from MSD.

Abstract
No optimal therapy exists to stop or cure chondral degeneration in osteoarthritis (OA). While the pathogenesis is unclear, there is consensus on the etiological involvement of both articular cartilage and subchondral bone. Compared to original bone, the substance of sclerotic bone is mechanically less solid. The osteoproliferative effect of Mg has been shown repeatedly during development of Mg-based osteosynthesis implants. The aim of the present study was to examine the influence of implanted high-purity Mg cylinders on subchondral bone quality in a rabbit OA model. 10 New Zealand White rabbits received into the knee either 20 empty drill holes or 20 drill holes, which were additionally filled with one Mg cylinder each. Follow-up was at 8 weeks. Micro-computed tomography (µCT) was performed. After euthanasia, cartilage condition was determined, bone samples were collected and processed for histological evaluation and elemental imaging by micro-X-ray fluorescence spectrometry (µXRF). Articular cartilage collected post-mortem showed different stages of lesions, from mild alterations up to exposed subchondral bone, which tended to be slightly lower in animals with implanted Mg cylinders. µCT showed significantly increased bone volume in the Mg group. Also, histological evaluation revealed distinct differences. While right, operated limbs did not show any significant difference, left, non-operated controls showed significantly less changes in articular cartilage in the Mg group. A distinct influence of implanted cylinders of pure Mg on subchondral bone of osteoarthritic rabbits was shown. Subsequent evaluations, including other time points and alternative alloys, will show if this could alter OA progression.

Grief and loss in old age: Exploration of the association between grief and depression. J Affect Disord 2021; 283:285-292. [PMID: 33578340 DOI: 10.1016/j.jad.2021.02.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 01/13/2021] [Accepted: 02/01/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND The proportion of older adults is increasing due to demographic changes. Depression belongs to the most common mental disorders in late life. The loss of an emotionally significant person is a risk factor for the development of depression. The aim of this study is to analyze the association between depression and grief burden resulting from loss. Based on prior evidence, we examined loneliness as a possible mediator and social support as possible moderator of this association. METHODS The cross-sectional analyses are based on a sample (N = 863) of study participants aged 75+ (M = 81.4 years, SD = 4.4, 62.2% female) with loss experience deriving from the multicenter prospective German cohort study AgeMooDe. Regression analyses (moderated mediation) were performed. RESULTS With increasing age (β = 0.10, p = .005) and grief burden (β = 0.33, p <. 001) depression severity increased. There was an indirect mediating effect of loneliness on the correlation of grief burden and depression (b = 0.04, CI [0.03, 0.05]), but no moderating effect of social support on the correlation of grief burden and loneliness. People living alone had a significantly higher risk of depression, increased loneliness and lack of social support. LIMITATIONS Assessments were based on self-reporting and recorded dimensionally. The cross-sectional design limits conclusions about directions and causality of associations. Sampling bias cannot be completely excluded. CONCLUSION The study provides empirical evidence and a better understanding of the association between grief and depression among the very old and the mediating role of loneliness.

Abstract
Vaginal lactobacilli (LAB) in probiotic formulas constitute a promising alternative for microbiome reconstitution and for the prevention and treatment of urogenital infections. A double-blind, randomised clinical trial was conducted to assess the safety of LAB-gelatine capsules vaginally administered to healthy sexually active women. Participants were randomised into three groups: intervention A: Lactobacillus reuteri CRL1324, Lactobacillus gasseri CRL1263 and CRL1307; intervention B: Lactobacillus rhamnosus CRL1332, L. gasseri CRL1256 and CRL1320; and intervention C: placebo. In a survey and clinical evaluation, participants received a blister with 7 capsules to be administered 1 per day. A second sampling and a new survey were conducted 3-10 days after completing application. Colposcopy was performed to assess adverse effects on vaginal-cervical mucosa. Vaginal swabs were taken for Gram staining to determine the Nugent score, and obtainment of viable-cell cultures to quantify cultivable lactic acid bacteria and pathogens. The main outcomes evaluated were overall satisfaction and secondary effects, including discomfort, urogenital infection, inflammatory response or other symptoms. No significant differences were found in Nugent score or in leukocyte numbers in vaginal samples either before or after the three interventions. However, a tendency to decrease in both the Nugent score and in leukocyte numbers was observed after interventions A and B, though not after C. A significant increase in cultivable lactobacilli was determined after LAB interventions. No severe adverse events were detected. LAB-containing capsules were well tolerated by subjects, so they could be proposed as an adequate alternative to restore vaginal lactobacilli in sexually active women.

Abstract
BACKGROUND Dementia is a major challenge for society and its impact will grow in the future. Informal care is an essential part of dementia care. Previous studies considered informal care as a whole and not by its components. OBJECTIVE We aimed to assess the degree of association between specific informal care services and dementia. MATERIAL AND METHODS This analysis is based on data from the seventh wave of the AgeCoDe/AgeQualiDe study. Dementia was diagnosed based on the DSM-IV criteria. Severity of dementia was assessed and categorized by means of the Clinical Dementia Rating and eight individual informal care services were considered. Logistic regression models were used to assess associations. RESULTS Of the 864 participants 18% suffered from dementia (very mild: 4%; mild: 6%; moderate: 5%; severe: 3%). All informal care services were significantly associated with dementia, with an emphasis on "supervision", "regulation of financial matters" and "assistance in the intake of medication". Considering different degrees of dementia severity, similar results arose from the analyses. All three aforementioned services showed a pronounced association with all degrees of dementia severity, except for supervision and very mild dementia. CONCLUSION The provision of all types of informal care services is associated with dementia. The association is pronounced for services that can be more easily integrated into the daily routines of the informal caregiver. Policy makers who plan to integrate informal care into the general care arrangements for dementia should consider this.

Abstract
The study is focussing towards Metal Injection Moulding (MIM) of Mg-alloys for biomedical implant applications. Especially the influence of the sintering processing necessary for the consolidation of the finished part is in focus of this study. In doing so, the chosen high strength EZK400 Mg-alloy powder material was sintered using different sintering support bottom plate materials to evaluate the possibility of iron impurity pick up during sintering. It can be shown that iron pick up took place from the steel bottom plate into the specimen. Despite the fact that a separating boron nitrite (BN) barrier layer was used and the Mg-Fe phase diagram is not predicting any significant solubility to each other. As a result of this study a new bottom plate material not harming the sintering and the biodegradation performance of the as sintered material, namely a carbon plate material, was found.

Abstract
ZusammenfassungWenig ist bekannt, ob Ärzte sich für die Versorgung von dementen Patienten kompetent fühlen und ob eine fehlende Kompetenz die Einstellung zu Demenzkranken und das professionelle Verhalten beeinflusst. Noch weniger weiß man, ob Hausärzte und Spezialisten sich in dieser Hinsicht voneinander unterscheiden. Ziel dieser Studie war das Verhältnis zwischen Kompetenz, Grundeinstellung und professionellem Verhalten von Ärzten in der ambulanten Versorgung in Deutschland zu untersuchen. Methoden: Eine standardisierte postalische Befragung wurde an 389 Hausärzte und 239 Neurologen und Psychiater verschickt. Der Befragung bestand aus 49 Aussagen, zu denen die Ärzte auf einer 6-Punkte-Likert-Skala ihre Zustimmung oder Ablehnung angeben sollten. Die Rücklaufquote betrug 54% für die Hausärzte und 40% für die Spezialisten. Ergebnisse: Hausärzte und Spezialisten fühlen sich kompetent für die Versorgung Demenzkranker, bei den Spezialisten ist dieses Gefühl stärker. Kein Unterschied fand sich hinsichtlich der Grundeinstellung zur Versorgung Demenzkranker. In beiden Ärztegruppen hatten etwa 15% eine deutlich negative Einstellung. Insbesondere bei den Hausärzten zeigte sich ein Zusammenhang zwischen subjektiver Kompetenzeinschätzung, Grundeinstellung und professionellem Verhalten (z. B. Frühdiagnose und Fallsuche, therapeutisches Verhalten). Schlussfolgerung: Speziell für Hausärzte können Fortbildungsangebote, die die Kompetenz, aber auch die Grundeinstellung zur Versorgung Demenzkranker verbessern, einen direkten positiven Einfluss auf die alltägliche Versorgung dieser Patientengruppe haben.

Abstract
OBJECTIVES The aim of this study was to identify determinants of outpatient health care utilization among the oldest old in Germany longitudinally. DESIGN Multicenter prospective cohort "Study on Needs, health service use, costs and health-related quality of life in a large sample of oldest-old primary care patients (85+)" (AgeQualiDe). SETTING Individuals in very old age were recruited via GP offices at six study centers in Germany. The course of outpatient health care was observed over 10 months (two waves). PARTICIPANTS Primary care patients aged 85 years and over (at baseline: n=861, with mean age of 89.0 years±2.9 years; 85-100 years). MEASUREMENTS Self-reported numbers of outpatient visits to general practitioners (GP) and specialists in the past three months were used as dependent variables. Widely used scales were used to quantify explanatory variables (e.g., Geriatric Depression Scale, Instrumental Activities of Daily Living Scale, or Global Deterioration Scale). RESULTS Fixed effects regressions showed that increases in GP visits were associated with increases in cognitive impairment, whereas they were not associated with changes in marital status, functional decline, increasing number of chronic conditions, increasing age, and changes in social network. Increases in specialist visits were not associated with changes in the explanatory variables. CONCLUSION Our findings underline the importance of cognitive impairment for GP visits. Creating strategies to postpone cognitive decline might be beneficial for the health care system.

Abstract
OBJECTIVE To investigate causal factors of functional impairment in old age in a longitudinal approach. DESIGN A population-based prospective cohort study. SETTING Elderly individuals were recruited via GP offices at six study centers in Germany. They were observed every 1.5 years over six waves. PARTICIPANTS Three thousand two hundred fifty-six people aged 75 years and older at baseline. MEASUREMENTS Functional impairment was quantified by the Lawton and Brody Instrumental Activities of Daily Living scale (IADL) and the Barthel-Index (BI). RESULTS Fixed effects regressions revealed that functional impairment (IADL; BI) increased significantly with ageing (β=-.2; β=-1.1), loss of a spouse (β= .5; β=-3.1), not living alone in private household (β=-1.2; β=-5.5), depression (solely significant for IADL: β= .6) and dementia (β=-2.3; β=-18.2). The comorbidity score did not affect functional impairment. CONCLUSION Our findings underline the relevance of changes in sociodemographic variables as well as the occurrence of depression or dementia for functional impairment. While several of these causal factors for functional decline in the oldest old are inevitable, some may not be, such as depression. Therefore, developing interventional strategies to prevent depression might be a fruitful approach in order to delay functional impairment in old age.

Abstract
OBJECTIVE To investigate how visual impairment affects social ties in late life longitudinally. DESIGN Population-based prospective cohort study. SETTING Individuals in old age were recruited via general practitioners' offices (at six study centers) in Germany. They were interviewed every 18 months. PARTICIPANTS Individuals aged 75 years and above at baseline. Follow-up wave 2 (36 months after baseline, n=2,443) and wave 4 (72 months after baseline, n=1,618) were used for the analyses presented here. MEASUREMENTS Social ties were assessed using the 14-item form of the questionnaire for social support (F-SozU K-14). Visual impairment was self-rated on a three level Likert scale (no impairment, mild visual impairment, or severe/profound visual impairment). RESULTS Adjusting for sociodemographic factors, hearing impairment and comorbidity, fixed effects regressions revealed that the onset of mild visual impairment decreased the social support score, in particular the emotional support score. Additionally, the onset of mild hearing impairment decreased the social support score in men. Moreover, increasing age decreased the social support score in the total sample and in both sexes. Loss of spouse and increasing comorbidity did not affect the social support score. CONCLUSION Our results highlight the importance of visual impairment for social ties in late life. Consequently, appropriate strategies in order to delay visual impairment might help to maintain social ties in old age.

Abstract
BACKGROUND Palliative care is an approach that improves the quality of life of patients with incurable and progressive illnesses; therefore, in these situations physiotherapy can play an important role. AIM This study was carried out to examine the integration and utilization of physiotherapy in palliative and hospice care services in Germany. METHODS A cross-sectional survey including all palliative care units, specialized outpatient palliative care teams and hospices in Germany (n = 680) in 2013 was carried out. RESULTS The response rate was 43.5 % (n = 296). Physiotherapy is predominantly applied in palliative care units (79 %) but rarely in hospices (38 %) and outpatient palliative care teams (30 %). A structured physiotherapeutic assessment is rarely carried out even on palliative care units (26 %). Positive effects of physiotherapy are especially described for symptoms, such as edema, pain, constipation and dyspnea. CONCLUSION Despite its significant potential to relieve symptoms, physiotherapy is not systematically integrated into palliative care practice in Germany.

Abstract
BACKGROUND We analyzed the differences in morbidity patterns of chronic diseases between long-term care dependent persons in nursing homes compared to those dwelling in the community. We also investigated morbidity differences between long-term care need stages in Germany. MATERIALS AND METHODS The study included claims data of one nationwide operating statutory health insurance in 2006. Inclusion criteria were age ≥ 65 years, minimum 1 out of 46 diagnoses in at least 3 quarters of the year (n = 8,670). A comparison population was formed with n = 114,962. Prevalences, relative risks, and odds ratios for the risk of nursing home care were calculated. RESULTS In the bivariate analysis, only three chronic diseases - dementia, urinary incontinence, and chronic heart failure - showed a higher risk for nursing home care. Regression analysis revealed that only dementia showed higher odds related to the stage of nursing needs. CONCLUSION Among the chronic diseases, only dementia shows a substantially elevated risk for nursing home care. Risk studies on other chronic diseases associated with higher risks of long-term care dependency and specific intervention strategies aiming at delaying or preventing nursing home admission should be developed.

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 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
Using a qualitative study approach (expert interview/focus group) the present work explores the question of the necessity of guideline recommendations for the treatment of depression in old age from the experts' perspective. In addition to positive aspects such as signal effect, pooling of knowledge and standardisation of treatment, also many doubts and obstacles are identified and place the practical feasibility of such a treatment recommendation in question. Different factors, such as content- or creative-related aspects (e. g., brevity and clarity) and development-related aspects (e. g. participation of all relevant professional societies) need to be taken into account in the development of guideline recommendations.

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
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
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 The diagnosis of dementia includes evidence of decline in cognitive functioning over time measured by objective cognitive tasks. Normative data for changes adjusted for the impact of socio-demographic factors on cognitive test performance are lacking to interpret changes in Mini-Mental State Examination (MMSE) test scores. METHOD As part of the German Study on Ageing, Cognition and Dementia in Primary Care Patients (AgeCoDe Study), a sample of 1090 cognitively healthy individuals, aged 75 years and older, was assessed at 1.5-year intervals over a period of 4.5 years using the MMSE. Age- and education-specific Reliable Change Indices (RCIs) were computed. RESULTS Age and education were significantly associated with MMSE test performance, and gender indicated no impact. Across different age and education subgroups, changes from at least 2 up to 3 points indicated significant (i.e., reliable) changes in MMSE test scores at the 90% confidence level. Furthermore, the calculation of RCIs for individual patients is demonstrated. CONCLUSION This study provides age- and education-specific MMSE norms based upon RCI methods to interpret cognitive changes in older age groups. The computation of RCI scores improves the interpretation of changes in MMSE test scores by controlling for measurement error, practice effects, or regression to the mean.

Abstract
AIM OF THE STUDY Analysis of views of general practioners and nurses of interprofessional cooperation between general practititoners and nurses in the ambulatory care of dementia patients is presented. METHODS A survey was carried out among general practitioners and nurses caring for community dwelling dementia patients in Hamburg. RESULTS The majority of GPs and nurses consider interprofessional cooperation to be good and beneficial for their own work. GPs are generally more positive about the quality of cooperation than nurses. Joint sessions for planning and evaluation of care are seldom. Even so, more GPs than nurses evaluate the frequency of these meetings to be sufficient. Although nurses are more critical about the quality of the cooperation with the GPs, they seldom address the GP to express their criticism. CONSEQUENCES To make cooperation work, the matter should be part of the training of both physicians and nurses and the hierarchy between the 2 groups should be reduced.

Abstract
HISTORY AND CLINICAL FINDINGS A 85-year-old patient, initially treated for aspiration pneumonia on the intensive care unit acutely complained again of nausea which was immediately treated by an i. v. bolus of metoclopramide (MCP). Without another incident of aspiration she subsequently developed acutely massive dyspnoea, increasing cyanosis and somnolence. INVESTIGATION On physical exam the patient showed tachycardia, dyspnoea and progressive somnolence. Laboratory investigation showed no significant abnormalities other than improving inflammatory markers. Computer tomography of the chest as well as bronchoscopy also revealed no pathologies. Blood gas analysis (BGA) however showed a massive increase in methemoglobinemia from 0.5 % just prior to MCP injection to 53.1 % after MCP injection; simultaneously the pO2 decreased from 74 auf 54 mmHg and the pCO2 from 37.7 to 34.1 mmHg. TREATMENT AND COURSE Instant therapy with toluidine blue led to a dramatic improvement of the patient's symptoms as well as a rapid normalisation of the pathological BGA. Soon after the patient could be dismissed. CONCLUSION The development of a severe and acute methemoglobinemia following the administration of MCP is described in this case report. Rapidly evolving dyspnoea following administration of MCP should instantly lead to the consideration of acute methemoglobinemia as differential diagnosis. Rapid diagnosis by blood gas analysis and instant therapy by toloudine blue (TB) can effectively prevent a potentially lethal course. The pathogenesis, clinical presentation, diagnosis and therapy for methemoglobinemia are discussed.

Abstract
OBJECTIVE The objective of the study is to systematically analyze the prevalence of depression in latest life (75+), particularly focusing on age- and gender-specific rates across the latest-life age groups. DESIGN Relevant articles were identified by systematically searching the databases MEDLINE, Web of Science, Cochrane Library and Psycinfo and relevant literature from 1999 onwards was reviewed. Studies based on the community-based elderly population aged 75 years and older were included. Quality of studies was assessed. Meta-analysis was performed using random effects model. RESULTS 24 studies reporting age- and gender-specific prevalence of depression were found. 13 studies had a high to moderate methodical quality. The prevalence of major depression ranged from 4.6% to 9.3%, and that of depressive disorders from 4.5% to 37.4%. Pooled prevalence was 7.2% (95% CI 4.4-10.6%) for major depression and 17.1% (95% CI 9.7-26.1%) for depressive disorders. Potential sources of high heterogeneity of prevalence were study design, sampling strategy, study quality and applied diagnostics of latest life depression. CONCLUSIONS Despite the wide variation in estimates, it is evident that latest life depression is common. To reduce variability of study results, particularly sampling strategies (inclusion of nursing home residents and severe cognitively impaired individuals) for the old age study populations should be addressed more thoroughly in future research.

Abstract
OBJECTIVE To estimate net costs of dementia by degree of severity from a societal perspective, including a detailed assessment of costs of formal and informal nursing care. METHOD In a cross-sectional study, costs of illness were analysed in 176 dementia patients and 173 matched non-demented control subjects. Healthcare resource use and costs were assessed retrospectively by means of a questionnaire. Dementia patients were classified into three disease stages, and linear regression models were applied to estimate net costs of dementia by degree of severity. RESULTS Annual net costs of dementia by stage were approximately €15 000 (mild), €32 000 (moderate) and €42 000 (severe), corresponding to US-$21 450, 45 760 and 60 060 respectively. Across disease stages, nursing care accounted for approximately three-quarters of total costs, of which half resulted from informal care. In sensitivity analyses using different valuation methods for nursing care, total costs decreased or increased by more than 20%. CONCLUSION Net costs more than double across stages of dementia. Informal care accounts for a considerable share of nursing care costs, and the approach to valuation of informal care has a large impact on cost-of-illness estimates.

Abstract
Recent advances in the development of high-throughput genotyping platforms allow for the unbiased identification of genes and genomic sequences related to heritable traits. In this study, we analyzed human short-term memory, which refers to the ability to remember information over a brief period of time and which has been found disturbed in many neuropsychiatric conditions, including schizophrenia and depression. We performed a genome-wide survey at 909 622 polymorphic loci and report six genetic variations significantly associated with human short-term memory performance after genome-wide correction for multiple comparisons. A polymorphism within SCN1A (encoding the α subunit of the type I voltage-gated sodium channel) was replicated in three independent populations of 1699 individuals. Functional magnetic resonance imaging during an n-back working memory task detected SCN1A allele-dependent activation differences in brain regions typically involved in working memory processes. These results suggest an important role for SCN1A in human short-term memory.

Abstract
OBJECTIVES The need for recognition of mild cognitive impairment (MCI) in primary care is increasingly discussed because MCI is a risk factor for dementia. General Practitioners (GPs) could play an important role in the detection of MCI since they have regular and long-term contact with the majority of the elderly population. Thus the objective of this study is to find out how well GPs recognize persons with MCI in their practice population. DESIGN Cross-sectional study. SETTING Primary care chart registry sample. PARTICIPANTS 3,242 non-demented GP patients aged 75-89 years. MEASUREMENTS GPs assessed the cognitive status of their patients on the Global Deterioration Scale (GDS). Thereafter, trained interviewers collected psychometric data by interviewing the patients at home. The interview data constitute the basis for the definition of MCI cases (gold standard). RESULTS The sensitivity of GPs to detect MCI was very low (11-12%) whereas their specificity amounts to 93-94%. Patients with MCI with a middle or high level of education more often got a false negative assignment than patients with a low educational level. The risk of a false positive assignment rose with the patients' degree of comorbidity. GPs were better at detecting MCI when memory or two and more MCI-domains were impaired. CONCLUSION The results show that GPs recognise MCI in a very limited number of cases when based on clinical impression only. A further development of the MCI concept and its operationalisation is necessary. Emphasis should be placed on validated, reliable and standardised tests for routine use in primary care encompassing other than only cognitive domains and on case finding approaches rather than on screening. Then a better attention and qualification of GPs with regard to the recognition of MCI might be achievable.

Abstract
OBJECTIVES To provide age- and gender-specific incidence rates of MCI among elderly general practitioner (GP) patients (75+ years) and to identify risk factors for incident MCI. METHOD Data were derived from the longitudinal German Study on Ageing, Cognition and Dementia in Primary Care Patients (AgeCoDe). Incidence was calculated according to the 'person-years-at-risk' method. Risk factors were analysed using multivariate logistic regression models. RESULTS During the 3-year follow-up period, 350 (15.0%) of the 2331 patients whose data were included in the calculation of incidence developed MCI [person-years (PY) = 6198.20]. The overall incidence of MCI was 56.5 (95% confidence interval = 50.7-62.7) per 1000 PY. Older age, vascular diseases, the apoE epsilon4 allele and subjective memory complaints were identified as significant risk factors for future MCI. CONCLUSION Mild cognitive impairment is frequent in older GP patients. Subjective memory complaints predict incident MCI. Especially vascular risk factors provide the opportunity of preventive approaches.

Abstract
Infiltration capacity of bank filtration systems depends on water extraction and hydraulic resistance of the bed sediments. Lakebed hydraulics may be especially affected by clogging, which is dependent on settlement of fine particles, redox potential, and other factors. In the field, most of these processes are difficult to quantify, and thus, when calculating response to pumping the water flux across the sediment surface is assumed to be linearly dependent on the hydraulic gradient. However, this assumption was not adequate to describe conditions at a bank filtration site located at Lake Tegel, Berlin, Germany. Hence, we first assumed the leakage coefficient (or leakance) is spatially distributed and also temporally variant. Furthermore, observations show that the leakance is considerably higher in shallow than in deeper areas; hence, leakance was assumed to be dependent on the existence and thickness of an unsaturated zone below the lake. The proposed explanation of spatial and temporal variability in leakance involves a hypothesis for redox dependent and reversible biogeochemical clogging, supported by geochemical observations in surface water and ground water. Four leakance approaches are implemented in the ground water flow code MODFLOW2000 and calibrated by inverse modeling using the parameter estimation software PEST. These concepts are evaluated by examining the fit to the hydraulic heads, to infiltration measurements, transport modeling results, and considering the degrees of freedom due to the number of calibration parameters. The leakage concept based on the assumption of the influence of an unsaturated zone on clogging processes best explains the field data.
