Abstract
Background:Psoriasis is a frequent skin disease that can appear with an arthritic manifestation in approximately 30% of the cases [1]. The underlying excessive immune reaction caused by pro-inflammatory cytokines can be triggered by several risk factors [2]. Various subgroups of Dendritic cells (DCs) in the skin play a crucial role in the induction of the dermal inflammatory response [3].Objectives:As the role of peripheral blood DCs remains unknown and the cause of an arthritic manifestation is still not completely understood [4], this project aimed to detect differences in phenotype or function of peripheral blood DCs in psoriatic patients with or without arthritis.Methods:We analyzed peripheral blood cells of 60 psoriasis patients with and without arthritis. Different DC subpopulations were detected by flow cytometry. Monocyte-derived DCs were cultured with or without Lipopolysaccharides to gain immature (iDC) and mature (mDC) cells. The DC phenotype was determined by staining with CD80, CD83, CD86, CD206, CCR7, CD1a, HLA-DR, CD40, GPN-MB, DC209 and CD14. Their T-cell stimulatory capability was analyzed by co-incubation with Carboxyfluorescein succinimidyl ester stained lymphocytes and the quantification of CD4+ T-lymphocytes afterwards. To measure the migration capacity DCs were seated into transwell chambers with a semipermeable membrane and partly supplemented with Macrophage Inflammatory Protein 3 Beta (Mip3b). Migrated cells were detected by flow cytometry. Measured cell counts were normalized to cell counts without Mip3b stimulation.Results:Comparing the factor of increase of migrated mDC counts due to mip3b stimulation, we detected a significant lower rate in samples of patients with arthritis (PsA) compared to those of patients without (Ps). Assays of mDCs without mip3b stimulation showed a significant higher count of migrated cells in the samples of the arthritic group [Figure 1]. Cell counts with Mip3b stimulation did vary slightly in the groups. The DC subpopulations and the expression of analyzed cell surface proteins did not show significant differences. The amounts of stimulated T-Lymphocytes did not differ significantly.Figure 1.Migration essay showing mDCs following Mip3b (+miß3b) as multiples of mDCs without stimulation (-mip3b). The factor of increase is significantly lower in patients with arthritis (PsA) compared to patients without (Ps). Absolute counts of migrated mDCs without Mip3b are significantly higher in the arthritic group. Cell counts with stimulation do not differ significantly (data not shown). N=24, p<0.05Conclusion:CCL19 (Mip3b) is a potent ligand to the CCR7 receptor inducing migration of DCs towards the lymphatic node [5]. The CCR7 amounts on the DC surface did not differ significantly in the groups. The mDCs without CCL19 stimulation migrated in higher amounts in samples of arthritic patients. Cell counts of stimulated DCs showed only slight differences. These results could be generated by a different appearance of the DCs of arthritic patients that might facilitate migration. Further experiments focusing on this aspect should be performed. A possible effect of disruptive factors (age, sex, medication…) needs to be clarified.References:[1]Henes, J.C., et al.,High prevalence of psoriatic arthritis in dermatological patients with psoriasis: a cross-sectional study.Rheumatol Int, 2014.34(2): p. 227-34.[2]Lee, E.B., et al.,Psoriasis risk factors and triggers.Cutis, 2018.102(5s): p. 18-20.[3]Kim, T.G., S.H.

Abstract
PURPOSE To determine the prevalence of overweight and obesity, and to identify factors associated with obesity, among the oldest old. METHODS For this study, data from follow-up (FU) wave 7 and FU wave 8 of the "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) were used. At FU wave 7, the mean age was 88.9 years (SD: 2.9; 85-100 years). Body-mass-index (BMI) categories were defined according to the World Health Organization (WHO) thresholds: underweight (BMI < 18.5 kg/m²), normal weight (18.5 kg/m² ≤ BMI < 25 kg/m²), overweight (25 kg/m² ≤ BMI < 30 kg/m²), and obesity (BMI ≥ 30 kg/m²). Longitudinal regression analysis was used to determine factors associated with obesity. RESULTS At FU wave 7, 3.0 % were underweight, 48.9 % were normal weight, 37.9 % were overweight, and 10.2 % were obese. Regressions showed that the probability of obesity decreased with age (OR: 0.77 [95 % CI: .593-.999]) and less chronic conditions (OR: 1.32 [95 % CI: 1.11-1.57]). The probability of obesity was not associated with sex, educational level, marital status, social isolation, visual impairment, hearing impairment, depression, and dementia. CONCLUSION Nearly half of the individuals in very late life had excess weight. Thus, excess weight remains a major challenge, even in very old age. Given the demographic ageing in upcoming decades, this is an issue which we should be aware of.

Abstract
OBJECTIVES Social isolation is increasing in aging societies and several studies have shown a relation with worse cognition in old age. However, less is known about the association in the oldest-old (85+); the group that is at highest risk for both social isolation and dementia. METHODS Analyses were based on follow-up 5 to 9 of the longitudinal German study on aging, cognition, and dementia in primary care patients (AgeCoDe) and the study on needs, health service use, costs, and health-related quality of life in a large sample of oldest-old primary care patients (AgeQualiDe), a multi-center population-based prospective cohort study. Measurements included the Lubben Social Network Scale (LSNS-6), with a score below 12 indicating social isolation, as well as the Mini-Mental Status Examination (MMSE) as an indicator of cognitive function. RESULTS Dementia-free study participants (n = 942) were M = 86.4 (SD = 3.0) years old at observation onset, 68.2% were women. One third (32.3%) of them were socially isolated. Adjusted linear hybrid mixed effects models revealed significantly lower cognitive function in individuals with smaller social networks (β = 0.5, 95% CI = 0.3-0.7, p < .001). Moreover, changes in an individual's social network size were significantly associated with cognitive changes over time (β = 0.2, 95% CI = 0.1-0.4, p = .003), indicating worse cognitive function with shrinking social networks. CONCLUSION Social isolation is highly prevalent among oldest-old individuals, being a risk factor for decreases in cognitive function. Consequently, it is important to maintain a socially active lifestyle into very old age. Likewise, this calls for effective ways to prevent social isolation.

Abstract
Background: Multimorbidity in elderly patients is a major challenge for physicians, because of a high prevalence of and associations with many adverse outcomes. However, the mechanisms of progressing multimorbidity are not well-understood. The aim of our study was to determine if the progression of multimorbidity is influenced by health behaviour and social support and to analyse if the patients’ socio-economic status had an effect on these prognostic factors. Methods: The study was designed as prospective cohort study based on interviews of 158 GPs and 3189 patients randomly selected from GP records (response rate: 46.2%). Patients were aged 65–85 years at recruitment and observed in four waves of data collection (dropout rate: 41.5%). Statistical analyses of the ‘hot deck’ imputed data included multilevel mixed-effects linear regression allowing for random effects at the study centre and GP practice within study centre level. Results: Regarding cardiovascular and metabolic diseases, multimorbidity progressed more rapidly in patients who reported less physical activity (ß = −0.28; 95% confidence interval = −0.35 to −0.20), had more tobacco-related pack years (0.15; 0.07–0.22) and consumed less alcohol (−0.21; −0.31 to −0.12) at baseline. Multimorbidity related to psychiatric and pain-related disorders progressed more rapidly if the patients had less perceived social support (−0.31; −0.55 to −0.07) and reported less physical activity (−0.08; −0.15 to −0.02) at baseline. Education and income only slightly modified the effects of these variables. Conclusion: Depending on the multimorbidity cluster, different strategies should be used for slowing down the progression of multimorbidity. Changing lifestyle and increasing social support are beneficial for the entire group of elderly multimorbid patients – regardless of their socio-economic status. Registration: ISRCTN89818205

Abstract
Purpose Dealing with the high prevalence of pain among the oldest-old (+75) is becoming a major health issue. Therefore, the aim of the study was to uncover health-related lifestyle behaviors (HLB) and age-related comorbidities which may predict, influence and prevent pain in old age. Patients and methods In this longitudinal cohort study, data were obtained initially from 3.327 individuals aged 75+ from over 138 general practitioners (GP) during structured clinical interviews in 2003. Nine follow-ups (FU) were assessed until 2017. Available data from 736 individuals scoring in FU3 and FU7 were included in this analysis. Data were assembled in an ambulatory setting at participant's homes. Associations were tested using a linear regression model (model 1) and ordered logistic regression model (model 2). Results Statistical analyses revealed increased likelihood to experience pain for participants with comorbidities such as peripheral arterial disease (PAD) (coef. 13.51, P>t = 0.00) or chronic back pain (CBP) (coef. 6.64, P>t = 0.003) or higher body mass index (BMI) (coef. 0.57, P>t = 0.015) and, female gender (coef. 6.00, SE 3.0, t = 2.02, P>t = 0.044). Participants with medium education and former smokers showed significantly lower pain rating (coef. -5.05, P>t = 0.026; coef. -5.27, P>t = 0.026). Suffering from chronic back pain (OR = 2.03), osteoarthritis (OR = 1.49) or depressive symptoms (OR = 1.10) raised the odds to experience impairments in daily living due to pain. Physical activity showed no significant results. Conclusion Chronic conditions such as PAD, or CBP, female gender and higher BMI may increase the risk of experiencing more pain while successful smoking cessation can lower pain ratings at old age. Early and consistent support through GPs should be given to older patients in order to prevent pain at old age.

Abstract
BACKGROUND Suicide is one of the four most common causes of death in adolescence worldwide. Although it is well known that suicidal people often have insufficient communication strategies, the importance of family communication for adolescent suicidality has not yet been sufficiently explored. OBJECTIVE The aim of this study was to provide a systematic review of family communication as a risk factor for adolescent suicidal tendencies and to develop treatment recommendations. METHODS In this study a systematic literature search was conducted in PubMed, Embase, CENTRAL and PsychINFO. The methodological quality of the studies was evaluated and a summary prepared. RESULT A total of 195 studies were extracted and screened for their suitability. Of these studies, 7 which examined a total of 13,107 adolescents aged 11-22 years were included in this review and critically evaluated. Of the studies evaluated six found a correlative relationship between dysfunctional parent-child communication and adolescent suicidality. Communication with the mother appears to be more essential. CONCLUSION The results of this literature search indicate that functional communication with parents seems to be protective for suicidal adolescents. From this, recommendations can be derived for preventive measures in families with adolescents who are otherwise at increased risk of suicide. Longitudinal study designs are needed to conclusively answer the research question.

Abstract
AIM The purpose of this study was to investigate whether transpersonal trust (TPT) moderates the relationship between chronic conditions and general practitioner (GP) visits among the oldest old in Germany. METHODS The 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) was carried out. Individuals were recruited through GP offices at six study centers in Germany (follow-up wave 7). Primary care patients were aged ≥85 years (n = 861, mean age 89.0 years; range 85-100 years). The self-reported number of outpatient visits to the GP was used as the outcome measure. To explore religious and spiritual beliefs, the short form of the Transpersonal Trust scale was used. The presence or absence of 36 chronic conditions was recorded by the GP. RESULTS Multiple Poisson regressions showed that GP visits were positively associated with the number of chronic conditions (incidence rate ratio 1.03, P < 0.05). TPT moderated the relationship between chronic conditions and GP visits (incidence rate ratio 1.01, P < 0.05). The association between chronic conditions and GP visits was significantly more pronounced when TPT was high. CONCLUSION Our findings highlight the importance of TPT in the relationship between chronic conditions and GP visits. Future longitudinal studies are required to clarify this subject further.

Abstract
OBJECTIVE To analyze the association of anxiety symptoms with health care use and costs in people aged 85 and older. METHODS Baseline data from AgeQualiDe (N = 856), a multicenter prospective cohort study of primary care patients aged 85 and older, were analyzed. Anxiety symptoms (Geriatric Anxiety Inventory-Short Form) and health care use were assessed via questionnaires. Health care use was monetarily valued using German unit costs to obtain sectoral (inpatient, outpatient, nursing care, medical supplies, and medication) and total costs. Health care use and costs were analyzed in regression models as a function of anxiety symptoms, as well as relevant covariates (predisposing, enabling, and other need characteristics based on the Behavioral Model of Health Care Use). RESULTS On a descriptive level, people with increased anxiety symptoms (12% of the sample) incurred on average € 10 909 (SD: 16 023) in the last 6 months, 31% more than those without increased anxiety (€ 8303, SD: 11 175; P = 0.12). Adjusting for predisposing, enabling, and other need characteristics, anxiety symptoms were not significantly associated with health care use or costs. Specifically, need characteristics (morbidity, cognitive decline, and functional impairment) were associated with total or sectoral costs, depending on the cost category analyzed. CONCLUSION In a sample of people of the oldest-old age group, the severity of anxiety symptoms was not associated with health care use or costs, when adjusting for relevant covariates. A longitudinal analysis could assess whether a change in anxiety symptom severity is associated with health care use or costs in old age.

Abstract
BACKGROUND The spectrum of indications for the use of membranes and scaffolds in the field of oral and maxillofacial surgery includes, amongst others, guided bone regeneration (GBR). Currently available membrane systems face certain disadvantages such as difficult clinical handling, inconsistent degradation, undirected cell growth and a lack of stability that often complicate their application. Therefore, new membranes which can overcome these issues are of great interest in this field. METHODS In this pilot study, we investigated polycaprolactone (PCL) scaffolds intended to enhance oral wound healing by means of melt electrospinning writing (MEW), which allowed for three-dimensional (3D) printing of micron scale fibers and very exact fiber placement. A singular set of box-shaped scaffolds of different sizes consisting of medical-grade PCL was examined and the scaffolds' morphology was evaluated via scanning electron microscopy (SEM). Each prototype sample with box sizes of 225 μm, 300 μm, 375 μm, 450 μm and 500 μm was assessed for cytotoxicity and cell growth by seeding each scaffold with human osteoblast-like cell line MG63. RESULTS All scaffolds demonstrated good cytocompatibility according to cell viability, protein concentration, and cell number. SEM analysis revealed an exact fiber placement of the MEW scaffolds and the growth of viable MG63 cells on them. For the examined box-shaped scaffolds with pore sizes between 225 μm and 500 μm, a preferred box size for initial osteoblast attachment could not be found. CONCLUSIONS These well-defined 3D scaffolds consisting of medical-grade materials optimized for cell attachment and cell growth hold the key to a promising new approach in GBR in oral and maxillofacial surgery.

Abstract
OBJECTIVE Subjective cognitive decline (SCD), the earliest symptom in preclinical Alzheimer's disease (AD), is insufficient to identify individuals at risk for AD dementia. Therefore, we aimed to investigate whether function in instrumental activities of daily living (IADL) contributes to identification. METHODS We analysed data of cognitively unimpaired participants of the prospective German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe) and its extension, the Study on Needs, Health Service Use, Costs and Health-related Quality of Life in a Large Sample of Oldest-old Primary Care Patients (AgeQualiDe), collected over 10.5 years. Development of AD dementia was quantified as incidence rates (IRs) per 1000 person-years. Cox regression was used to assess the association of SCD and IADL function in regard to incident AD dementia. RESULTS Of 1467 included individuals, 792 (54.0%) reported SCD at baseline. Impaired IADL were present in 50 (3.4%) individuals. IR for AD dementia was highest in individuals with SCD and impaired IADL (49.7; 95% CI, 24.8-99.3). Unadjusted and adjusted Cox analyses revealed an increased AD dementia risk for individuals with SCD and impaired IADL (uHR = 6.1; 95% CI, 2.9-13.0; P < 0.001; aHR = 2.5; 95% CI, 1.1-5.7; P < 0.05). CONCLUSIONS Consistent with the SCD concept, IADL function was largely well preserved in the majority of individuals with SCD. However, if difficulties in IADL were present, risk for AD dementia was increased. Therefore, screening for IADL impairment could serve as an economically viable indicator to assess AD dementia risk above and beyond SCD.

Prevalence of Anxiety Symptoms and Their Association With Loss Experience in a Large Cohort Sample of the Oldest-Old. Results of the AgeCoDe/AgeQualiDe Study. Front Psychiatry 2019; 10:285. [PMID: 31139097 PMCID: PMC6518947 DOI: 10.3389/fpsyt.2019.00285] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Accepted: 04/12/2019] [Indexed: 11/13/2022] Open
Abstract
Background: Anxiety in adults is a common mental health problem. However, studies on anxiety in the oldest-old are lacking. We sought to identify the age- and gender-specific prevalence of anxiety symptoms in a large sample of general practice patients. Furthermore, we investigated relevant associations of anxiety specifically with respect to recent experience of loss. Methods: Based on the German Study on Ageing, Cognition and Dementia in general practice patients, a sample of 897 patients aged 82 years and older was assessed. Anxiety was assessed using the short form of the Geriatric Anxiety Inventory (GAI-SF). For the assessment of loss, patients were asked whether there were cases of death in their closer social environment since the last assessment. Descriptive and logistic regression analyses were run. Results: Of the oldest-old individuals (aged 82+ years, mean age: 86.8), 14.5% (95% CI 12.4-16.8) suffered from anxiety symptoms. Highest prevalence rates were found for 82- to 85-year-old women (17.2%, 95% CI 12.6-22.1) and for 86- to 90-year-old patients (both sexes) in general (15.9%, 95% CI 12.6-19.2). Older individuals who experienced cases of death in their close social environment within the last 18 months had almost twice the odds [odds ratio (OR) 1.91, 95% confidence interval (CI) 1.15-3.17] of reporting anxiety compared to those without a recent loss. As expected, depression and impaired cognitive status were associated with the presence of anxiety symptoms. No relation was found between social network, gender, age, frailty, or physical illness and anxiety in regression analysis. Conclusions: This study provides for the first time age- and gender-specific prevalence rates of anxiety symptoms and associated risk factors among a large population-based sample of oldest-old primary care attenders. Anxiety is highly prevalent in individuals aged 82 years and older. Depression, impaired cognitive status, and recent experience of loss are associated with late-life anxiety. Our findings support the idea that recent experience of loss should be taken seriously in the context of clinical practice with respect to diagnosing and treating anxiety in old age.

Abstract
OBJECTIVE The purpose of this study was to examine the impact of falls on depressive symptoms among the oldest old in Germany longitudinally. METHODS Data were used from 2 waves of the 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). This study covers primary care patients ≥85 years (at baseline: n = 547, average age of 88.9 ± 3.0 years; ranging from 85 to 100 years). General practitioner-diagnosed falls were used as explanatory variable. The Geriatric Depression Scale was used as outcome measure. RESULTS Linear fixed effects regressions showed that the occurrence of falls is associated with an increase in depressive symptoms (β = .60, P = .02), whereas changes in marital status, ageing, social support, functional decline (instrumental activity of daily living), cognitive impairment, and an increase in chronic diseases did not affect depressive symptoms. In sensitivity analysis, an increase in depressive symptoms was associated with functional impairment (basic activities of daily living; Barthel index; β = -.04, P = .005). CONCLUSIONS Based on a large, population-based longitudinal study, this study underlined the impact of falls on depressive symptoms and consequently extended previous knowledge about an association between falls and depressive symptoms in the oldest old. Developing strategies to prevent falls might also help to prevent depressive symptoms.

Abstract
Abstract
Background and Objectives
We examined the validity of 5 successful aging (SA) operationalizations that assessed different facets of the SA construct (cognitive and physical health and disability; well-being; social engagement).
Research Design and Methods
A total of 2,478 participants (mean age = 82.5 years, standard deviation [SD] = 3.47) were studied. We used confirmatory factor analysis to investigate the relationships between facets and to determine the convergent validity as well as short-term (1.5 years) and long-term (4.5 years) predictive validity of the 5 SA operationalizations for measures of quality of life (QoL) and objective health outcomes.
Results
A general SA operationalization that included all SA facets but also allowed differences between them showed the best model fit and construct validity. A biomedical operationalization of SA that excluded either the well-being or the social engagement facet showed lower convergent and predictive validity for subjective measures (e.g., QoL) but higher associations with objective measures (e.g., health). A purely psychosocial SA operationalization that excluded the physiological facet did not allow good prediction of objective health outcomes.
Discussion and Implications
Our results suggest that a well-balanced SA operationalization should include measures assessing health, disability, well-being, and social engagement.

Abstract
Objective The objective of this paper is to examine the association between plasma levels of β2-microglobulin (β2MG), a protein previously associated with atherosclerosis, and the presence of carotid plaque (CP) or coronary artery calcium (CAC) in a cross-sectional cohort study of patients with systemic lupus erythematosus (SLE). Methods Patients with SLE were enrolled between June 2013 and May 2014. The presence of CP and CAC was assessed with ultrasonography and computed tomography scan, respectively. The presence of CP or CAC in the SLE patients was analyzed with respect to plasma levels of β2MG and renal function expressed as the estimated glomerular filtration rate (eGFR). Results The study cohort consisted of 147 patients, 89% women and 95% Caucasians. The median age was 46 (range: 21-75) years with a median disease duration of 14 years. CP and CAC was observed in 29 (20%) and 57 (39%) of patients, respectively. CP or CAC was seen in 62 (42%) patients and was associated with the highest quartile of plasma β2MG in patients with eGFR ≥ 90 ml/min/1.73 m2; OR = 18 (95% CI: 1.7-181). β2MG adjusted for eGFR was also associated with presence of CP or CAC in the total cohort. The exclusion of 25 patients with a prior history of cardiovascular disease did not change the observed associations. Conclusion In this study, we found significant associations between imaging markers of atherosclerosis and high plasma levels of plasma β2MG. These data suggest that β2MG is a candidate for further study as a biomarker for atherosclerosis in SLE.

Abstract
PURPOSE Psychosomatic symptoms and mental health problems are highly prevalent in multimorbid elderly people challenging general practitioners to differentiate between normal stress and psychopathological conditions. The 4DSQ is a Dutch questionnaire developed to detect anxiety, depression, somatization, and distress in primary care. This study aims to analyze measurement equivalence between a German version and the original Dutch instrument. METHODS A Dutch and a German sample of multimorbid elderly people, matched by gender and age, were analyzed. Equivalence of scale structures was assessed by confirmatory factor analysis (CFA). To evaluate measurement equivalence across languages, differential item functioning (DIF) was analyzed using Mantel-Haenszel method and hybrid ordinal logistic regression analysis. Differential test functioning (DTF) was assessed using Rasch analysis. RESULTS A total of 185 German and 185 Dutch participants completed the questionnaire. The CFA confirmed one-factor models for all scales of both 4DSQ versions. Nine items in three scales were flagged with DIF. The anxiety scale showed to be free of DIF. DTF analysis revealed negligible scale impact of DIF. CONCLUSIONS The German 4DSQ demonstrated measurement equivalence to the original Dutch instrument. Hence, it can be considered a valid questionnaire for the screening for mental health problems in primary care.

Abstract
BACKGROUND In the future, an increase in health care needs in the elderly is expected. Reports on unmet care needs of the oldest old with cognitive disorders are pending. This study aims at exploring unmet needs in the oldest old primary care patients with mild cognitive impairment (MCI) and dementia. Furthermore, the association between sociodemographic and clinical factors and unmet needs ought to be analyzed. METHODS Based on the study "Needs, Health Service Use, Costs and Health-Related Quality of Life in a Large Sample of Oldest-Old Primary Care Patients (85+)" (AgeQualiDe), 749 patients (unimpaired, MCI, and dementia) aged 85 years and older, their relatives (n = 421), and general practitioners (GPs) (n = 607) were assessed. Descriptive, inferential, and regression analyses were run. RESULTS Most unmet needs were observed in dementia patients, although needs were less frequently rated as unmet by dementia patients themselves as compared to relatives and GPs. Unmet needs were associated with MCI and dementia; other risk factors were age, education, and marital status. CONCLUSION This study provides first data on unmet needs according to different perceptions in the elderly with MCI and dementia in Germany. Need assessments should be part of medical examinations to ensure a high-quality health care in the elderly.

Abstract
BACKGROUND The prevalence of pain is very common in the oldest age group. Managing pain successfully is a key topic in primary care, especially within the ageing population. Different care settings might have an impact on the prevalence of pain and everyday life. METHODS Participants from the German longitudinal 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) were asked to rate their severity of pain as well as the impairment with daily activities. Besides gender, age, education, BMI and use of analgesics we focused on the current housing situation and on cognitive state. Associations of the dependent measures were tested using four ordinal logistic regression models. Model 1 and 4 consisted of the overall sample, model 2 and 3 were divided according to no cognitive impairment (NCI) and mild cognitive impairment (MCI). RESULTS Results show a decline in pain at very old age but nonetheless a high prevalence among the 85+ year olds. Sixty-three per cent of the participants report mild to severe pain and 69% of the participants mild to extreme impairment due to pain with daily activities. Use of analgesics, depression and living at home with care support are significantly associated with higher and male gender with lower pain ratings. CONCLUSIONS Sufficient pain management among the oldest age group is inevitable. Outpatient care settings are at risk of overlooking pain. Therefore focus should be set on pain management in these settings.

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
OBJECTIVES Standard inflammatory markers and chest radiography lack the ability to discriminate bacterial from non-bacterial lower respiratory tract infection (LRTI). Cytokine profiles may serve as biomarkers for LRTI, but their applicability to identify aetiology, severity of disease and need for antibiotic prescription in children remains poorly defined. Objectives were to determine the cytokine kinetic profiles over 5 days in paediatric patients with LRTI, to investigate the relationship between cytokine patterns, and clinical and laboratory variables. METHODS We included patients aged 1 month to 18 years, with febrile LRTI and three consecutive cytokines measurements on days 1, 3 and 5 of a randomized controlled trial (ProPAED study). We evaluated differences in cytokine concentrations between days and associations with clinical and laboratory variables. RESULTS A total of 181 patients (median age 4.1 years) were included; 72/181 (40%) received antibiotics. Serum concentrations of interferon (IFN)-γ, interleukin (IL)-1ra, IL-6, IL-10, IFN-γ-inducible protein (IP)-10 and tumor necrosis factor-α were elevated on day 1 and decreased subsequently, with the greatest decline between day 1 and 3 (by -8 to >-94%). Procalcitonin (PCT) and C-reactive protein (CRP) values showed a protracted decrease with the most prominent reduction in concentrations between days 3 and 5. Significantly elevated IL-6 concentrations were associated with hospital admission, antibiotic treatment, and prolonged antibiotic treatment. Bacteraemic LRTI patients had higher concentrations of IL-1ra (p <0.0055) and IL-6 (p <0.0055) on day 1. CONCLUSIONS We observed an earlier decrease of elevated cytokines compared to PCT or CRP. Both pro- and anti-inflammatory cytokines may serve as markers for severity of LRTI.

Abstract
BACKGROUND Late-life depression is frequently accompanied by cognitive impairments. OBJECTIVE Whether these impairments indicate a prodromal state of dementia, or are a symptomatic expression of depression per se is not well-studied. METHODS In a cohort of very old initially non-demented primary care patients (n = 2,709, mean age = 81.1 y), cognitive performance was compared between groups of participants with or without elevated depressive symptoms and with or without subsequent dementia using ANCOVA (adjusted for age, sex, and education). Logistic regression analyses were computed to predict subsequent dementia over up to six years of follow-up. The same analytical approach was performed for lifetime major depression. RESULTS Participants with elevated depressive symptoms without subsequent dementia showed only small to medium cognitive deficits. In contrast, participants with depressive symptoms with subsequent dementia showed medium to very large cognitive deficits. In adjusted logistic regression models, learning and memory deficits predicted the risk for subsequent dementia in participants with depressive symptoms. Participants with a lifetime history of major depression without subsequent dementia showed no cognitive deficits. However, in adjusted logistic regression models, learning and orientation deficits predicted the risk for subsequent dementia also in participants with lifetime major depression. CONCLUSION Marked cognitive impairments in old age depression should not be dismissed as "depressive pseudodementia", but require clinical attention as a possible sign of incipient dementia. Non-depressed elderly with a lifetime history of major depression, who remained free of dementia during follow-up, had largely normal cognitive performance.

Abstract
ZusammenfassungDie Einstellungen der Hausärzte zum Thema Demenz scheinen einen großen Einfluss auf die Versorgung dieser Patientengruppe und ihrer Angehörigen zu haben. Dabei spielen sowohl das Wissen der Ärzte, aber auch affektive Faktoren (wie z.B. Tabuisierungstendenzen) und externe Schwierigkeiten (wie z.B. Zeitmangel in der Praxis) eine Rolle. Diese wirken sich auf die Versorgung im gesamten Krankheitsverlauf aus, von der Erkennung bis zur Pflege im Endstadium der Demenz. Sowohl in der Forschung, als auch bei Fortbildungsprogrammen muss berücksichtigt werden, dass nicht allein mögliche Wissenslücken der Hausärzte für eine defizitäre Versorgung verantwortlich sind.

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 how social support affects functional impairment (FI) in late life in a longitudinal approach. Methods in a multicenter prospective cohort study, subjects in old age (≥75 years at baseline) were interviewed every 1.5 years. Social support was quantified in the follow-up (FU) Waves 2 and 4 (FU Wave 2: n = 2,349; FU Wave 4: n = 1,484). FI was assessed by using the Lawton and Brody Instrumental Activities of Daily Living scale. Results fixed effects regressions showed that a decrease in social support is associated with FI in the total sample and in both sexes. The effect on FI was most pronounced with the dimension social integration, whereas changes in practical support only affected FI in the total sample and changes in emotional support only affected FI in men. Conclusions our findings emphasise the importance of social support for functional status in late life. Thus, strengthening social support in old age might be effective in maintaining functional abilities.

Abstract
BACKGROUND Thus far, only a few longitudinal studies investigated the impact of social engagement on health-related quality of life (HRQoL) and depressive symptoms in old age. Therefore, we aimed to examine the impact of social engagement on HRQoL and depressive symptoms in late life. METHODS Individuals aged 75 years and over at baseline were interviewed every 1.5 years in a multicenter prospective cohort study in Germany. While HRQoL was quantified by using the Visual Analogue Scale (EQ VAS) of the EQ-5D instrument, depressive symptoms was assessed by using the Geriatric Depression Scale (GDS). Individuals reported the frequency ("never" to "every day") of social engagement (e.g., engagement in the church, as a volunteer, in a party, or in a club) in the last four weeks. Fixed effects regressions were used to estimate the effect of social engagement on the outcome variables. RESULTS After adjusting for age, marital status, functional status and chronic diseases, fixed effects regressions revealed that the onset of social engagement markedly increased HRQoL and considerably decreased depressive symptoms in the total sample and in women, but not men. CONCLUSIONS Our findings corroborate the relevance of social engagement for HRQoL and depressive symptoms in old age. Encouraging the individuals to start, maintain and expand social engagement in late life might help to maintain and improve HRQoL and decrease depressive symptoms.

Abstract
BACKGROUND Completion of advance directives (ADs) and power of attorney (POA) documents may protect a person's autonomy in future health care situations when the individual lacks decisional capacity. As such situations become naturally much more common in old age, we specifically aimed at providing information on (i) the frequency of ADs/POA in oldest-old individuals and (ii) factors associated with having completed ADs/POA. METHODS We analyzed data of oldest-old primary care patients (85+ years; including community-dwelling and institutionalized individuals) within the German AgeQualiDe study. Patients were initially recruited via their general practitioners (GPs). We calculated frequencies of ADs and POA for health care with 95% confidence intervals (CI) and used multivariable logistic regression analysis to evaluate the association between having ADs and POA and participants' socio-demographic, cognitive, functional, and health-related characteristics. RESULTS Among 868 GP patients participating in AgeQualiDe (response = 90.9%), n = 161 had dementia and n = 3 were too exhausted/ill to answer the questions. Out of the remaining 704 (81.1%) dementia-free patients (mean age = 88.7 years; SD = 3.0), 69.0% (95%-CI = 65.6-72.4) stated to having ADs and 64.6% (95%-CI = 61.1-68.2) to having a POA for health care. Individual characteristics did not explain much of the variability of the presence/absence of ADs and POA (regression models: Nagelkerke's R2 = 0.034/0.051). The most frequently stated reasons for not having ADs were that the older adults trust their relatives or physicians to make the right decisions for them when necessary (stated by 59.4% and 44.8% of those without ADs). Among the older adults with ADs, the majority had received assistance in its preparation (79.0%), most frequently from their children/grandchildren (38.3%). Children/grandchildren were also the most frequently stated group of designated persons (76.7%) for those with a POA for health care. CONCLUSIONS Our findings suggest a high dissemination of ADs and POA for health care in the oldest-old in Germany. Some adults without ADs/POA perhaps would have completed advance care documents, if they had had received more information and support. When planning programs to offer advanced care planning to the oldest old, it might be helpful to respond to these specific needs, and also to be sensitive to attitudinal differences in this target group.

Abstract
OBJECTIVE We aimed at identifying differences regarding cognition, depressive symptoms and health-related quality of life between members of private and statutory health insurance (SHI) in very old age in Germany. METHODS Cross-sectional data were gathered from the multicenter prospective "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), covering primary care patients aged ≥ 85 years (n = 854; with 773 members of SHI). The Global Deterioration Scale measured cognition, the Geriatric Depression Scale assessed depressive symptoms, and health-related quality of life was measured by using a Visual Analogue Scale (EQ-VAS). RESULTS While members of private health insurance showed slightly better cognitive function, less depressive symptoms and better health-related quality of life descriptively, regression models showed that none of these differences was statistically significant. CONCLUSIONS There are no differences between members of private health insurance and SHI regarding cognitive function, depressive symptoms and health-related quality of life in very old age.

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
OBJECTIVES To investigate mortality risk and survival time in new-incident cases of cognitive impairment (CI) in old age. DESIGN Prospective cohort study in six German cities. SETTING German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe). PARTICIPANTS Two thousand eighty-nine nondemented GP patients aged 75+. MEASUREMENTS Every 18 months, trained psychologists and physicians conducted structured clinical interviews at the participants' homes. Dates of death were obtained from relatives, general practitioner (GP), or the local registry offices. We used the Kaplan-Meier survival method to estimate survival times of individuals with and without incident CI and multivariable Cox proportional hazards regressions to assess the association between CI and mortality risk, controlled for covariates. RESULTS Out of the 2,089 included patients at follow-up I, 859 (41.1%) died during the subsequent mean observation period of 8.0 years. Patients with incident CI at follow-up I showed a significantly higher case-fatality rate per 1,000 person-years (74.2, 95% CI = 64.2-84.2 vs 47.8, 95% CI = 44.6-51.0) and a significantly shorter mean survival time in the observation period than those without (7.8 vs 9.1 years; P < .001). The association between incident CI and mortality remained significant in the multivariable Cox analyses-incident CI was associated with a 42% increased, incident severe CI with a 75% increased mortality risk. CONCLUSION Our findings suggest an elevated mortality risk in newly acquired cognitive deficits in old age. Even though further studies are required to analyze potential underlying mechanisms, our findings support the notion that such cognitive deficits should be taken seriously in clinical practice not only for an increased risk of developing dementia but also for a broader range of possible adverse health outcomes.

Abstract
Increased production and use of zinc oxide nanoparticles (ZnO-NPs) in consumer products has prompted the scientific community to investigate their potential toxicity, and understand their impact on the environment and organisms. Molecular mechanisms involved in ZnO-NP toxicity are still under debate and focus essentially on high dose expositions. In our study, we chose to evaluate the effect of sub-toxic doses of ZnO-NPs on human hepatocytes (HepG2) with a focus on metal homeostasis and redox balance disruptions. We showed massive dissolution of ZnO-NPs outside the cell, transport and accumulation of zinc ions inside the cell but no evidence of nanoparticle entry, even when analysed by high resolution TEM microscopy coupled with EDX. Gene expression analysis highlighted zinc homeostasis disruptions as shown by metallothionein 1X and zinc transporter 1 and 2 (ZnT1, ZnT2) over-expression. Major oxidative stress response genes, such as superoxide dismutase 1, 2 and catalase were not induced. Phase 2 enzymes in term of antioxidant response, such as heme oxygenase 1 (HMOX1) and the regulating subunit of the glutamate-cysteine ligase (GCLM) were slightly upregulated, but these observations may be linked solely to metal homeostasis disruptions, as these actors are involved in both metal and ROS responses. Finally, we observed abnormal mitochondria morphologies and autophagy vesicles in response to ZnO-NPs, indicating a potential role of mitochondria in storing and protecting cells from zinc excess but ultimately causing cell death at higher doses.

Abstract
INTRODUCTION Previous studies have demonstrated that an overall high level of mental work demands decreased dementia risk. In our study, we investigated whether this effect is driven by specific mental work demands and whether it is exposure dependent. METHODS Patients aged 75+ years were recruited from general practitioners and participated in up to seven assessment waves (every 1.5 years) of the longitudinal AgeCoDe study. Analyses of the impact of specific mental work demands on dementia risk were carried out via multivariate regression modeling (n = 2315). RESULTS We observed a significantly lower dementia risk in individuals with a higher level of "information processing" (HR, 0.888), "pattern detection" (HR, 0.878), "mathematics" (HR, 0.878), and "creativity" (HR, 0.878). Yet, exposure-dependent effects were only significant for "information processing" and "pattern detection." DISCUSSION Our longitudinal observations suggest that dementia risk may be reduced by some but not all types of mental work demands.

Abstract
Multimodal MRI is the state of the art method for clinical diagnostics and therapy monitoring of the spinal cord, with MRS being an emerging modality that has the potential to detect relevant changes of the spinal cord tissue at an earlier stage and to enhance specificity. Methodological challenges related to the small dimensions and deep location of the human spinal cord inside the human body, field fluctuations due to respiratory motion, susceptibility differences to adjacent tissue such as vertebras and pulsatile flow of the cerebrospinal fluid hinder the clinical application of (1) H MRS to the human spinal cord. Complementary to previous studies that partly addressed these problems, this work aims at enhancing the signal-to-noise ratio (SNR) of (1) H MRS in the human spinal cord. To this end a flexible tight fit high density receiver array and ultra-high field strength (7 T) were combined. A dielectric waveguide and dipole antenna transmission coil allowed for dual channel RF shimming, focusing the RF field in the spinal cord, and an inner-volume saturated semi-LASER sequence was used for robust localization in the presence of B1 (+) inhomogeneity. Herein we report the first 7 T spinal cord (1) H MR spectra, which were obtained in seven independent measurements of 128 averages each in three healthy volunteers. The spectra exhibit high quality (full width at half maximum 0.09 ppm, SNR 7.6) and absence of artifacts and allow for reliable quantification of N-acetyl aspartate (NAA) (NAA/Cr (creatine) 1.31 ± 0.20; Cramér-Rao lower bound (CRLB) 5), total choline containing compounds (Cho) (Cho/Cr 0.32 ± 0.07; CRLB 7), Cr (CRLB 5) and myo-inositol (mI) (mI/Cr 1.08 ± 0.22; CRLB 6) in 7.5 min in the human cervical spinal cord. Thus metabolic information from the spinal cord can be obtained in clinically feasible scan times at 7 T, and its benefit for clinical decision making in spinal cord disorders will be investigated in the future using the presented methodology.

Abstract
Current echocardiographic assessments of coronary vascular territories use the 17-segment model and are based on general assumptions of coronary vascular distribution. Fusion of 3D echocardiography (3DE) with multidetector computed tomography (MDCT) derived coronary anatomy may provide a more accurate assessment of left ventricular (LV) territorial function. We aimed to test the feasibility of MDCT and 3DE fusion and to compare territorial longitudinal strain (LS) using the 17-segment model and a MDCT-guided vascular model. 28 patients underwent 320-slice MDCT and transthoracic 3DE on the same day followed by invasive coronary angiography. MDCT (Aquilion ONE, ViSION Edition, Toshiba Medical Systems) and 3DE apical full-volume images (Artida, Toshiba Medical Systems) were fused offline using a dedicated workstation (prototype fusion software, Toshiba Medical Systems). 3DE/MDCT image alignment was assessed by 3 readers using a 4-point scale. Territorial LS was assessed using the 17-segment model and the MDCT-guided vascular model in territories supplied by significantly stenotic and non-significantly stenotic vessels. Successful 3DE/MDCT image alignment was obtained in 86 and 93 % of cases for reader one, and reader two and three, respectively. Fair agreement on the quality of automatic image alignment (intra-class correlation = 0.40) and the success of manual image alignment (Fleiss' Kappa = 0.40) among the readers was found. In territories supplied by non-significantly stenotic left circumflex arteries, LS was significantly higher in the MDCT-guided vascular model compared to the 17-segment model: -15.00 ± 7.17 (mean ± standard deviation) versus -11.87 ± 4.09 (p < 0.05). Fusion of MDCT and 3DE is feasible and provides physiologically meaningful displays of myocardial function.

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 Multimorbidity is a highly prevalent health problem, which may reduce adherence, produce conflicts in treatment, and is not yet supported by evidence-based clinical recommendations. Many older people suffer from more than one chronic disease as well as from chronic pain. There is some evidence that disease management can become more complex if multimorbid patients suffer from chronic pain. In order to better consider the patients' comorbidity spectrum in clinical pain treatment recommendations, evidence is needed regarding which disease combinations are frequently related with the presence of chronic pain. Therefore, our aim is to identify diseases and disease combinations in a multimorbid population, which are associated with the patient-reported presence of chronic pain. METHODS Analyses are based on cross-sectional data of the MultiCare Cohort Study, an observational cohort study based on interviews with 3189 multimorbid patients aged 65+, randomly selected from 158 practices, and their GPs. The response rate was 46.2 %. Data were collected in GP interviews and comprehensive patient interviews. Diseases and disease combinations associated with chronic pain were identified by CART (classification and regression tree) analyses performed separately for both genders. 46 chronic conditions were used as predictor variables and a dichotomized score from the Graded Chronic Pain Scale was used as outcome variable. RESULTS About 60 % of the study participants were female. Women more often reported chronic pain than men. The most important predictor of a higher pain level in the female population was chronic low back problems, especially if combined with chronic gastritis, hyperuricemia/gout, cardiac insufficiency, neuropathies or depression. Regarding the pain level the male population was also divided best by chronic low back problems, especially if combined with intestinal diverticulosis, neuropathies or chronic ischemic heart disease. CONCLUSIONS Our analyses are a first step in identifying diseases and disease combinations that are related to chronic pain. The most important condition seems to be low back problems. Back pain and pain in other body regions seems to be interrelated with cardiometabolic conditions. In women, psychosocial issues like depression also seem to be relevant.

Abstract
PURPOSE Care provided in the community for dementia patients on an individual basis may be very time consuming. Yet, little is known about the factors affecting caregiving time for community-dwelling dementia patients. Thus, we aimed to investigate the predictors of informal and formal caregiving time for these patients in a longitudinal approach. METHOD Caregiving time for n = 126 community-dwelling dementia patients was assessed by proxy interviews in four assessments at 6-month intervals (1.5 years of longitudinal follow-up; AgeCoDe study). Measurement of informal caregiving time was based on a German adaptation of the Resource Utilization in Dementia questionnaire. Dementia severity was measured by the Clinical Dementia Rating (CDR). We used random effects models to estimate the effects of sociodemographic variables (age, gender, marital status and education), comorbidity and dementia severity on informal and formal caregiving time. RESULTS At the first assessment, mean age was 85.0 years (±3.2 years). The majority of patients was female (65.9 %), not married (divorced, single, widowed: 55.6 %) and had primary education (63.5 %). Furthermore, mean GDS was 4.4 (±0.8) and mean MMSE was 20.1 (±5.1). According to CDR, 43 individuals had very mild dementia, 55 individuals had mild dementia and 28 individuals had moderate/severe dementia. Moreover, mean total caregiving time was 3.4 h per day (±4.0). Thereof the main part represents informal caregiving time (2.3 h ± 3.4), whereas formal caregiving time was 1.2 h (±2.4). Dementia severity was associated with total caregiving time, mainly influenced by informal caregiving time. Age was positively associated with total caregiving time, driven by formal caregiving time, while being married was positively associated with total caregiving time, mainly affected by informal caregiving time. All need categories of informal caregiving time were strongly related to dementia severity, whereas none of the categories of formal caregiving time were related to dementia severity. CONCLUSIONS Our findings extend previous studies that found an association between informal caregiving time and dementia severity. Moreover, our findings highlight the role of informal care for community-dwelling dementia patients in Germany. Informal caregiving time strongly increases with dementia severity. Consequently, as the number of patients suffering from dementia is expected to increase considerably in the next decades, there is a paramount need to strengthen the informal care system to meet patients' needs.
