RESUMEN
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.

Changes in the working environment with respect to innovative working time models are also increasingly affecting patient care. The number of physicians working part-time, for example, is continuously rising. At the same time, a general increase in chronic diseases and multimorbid conditions as well as the growing shortage of medical staff, leads to more workload and dissatisfaction among this profession. This short overview summarizes the current study situation and associated consequences regarding working hours of physicians and gives a first explorative overview of possible solutions.
RESUMEN
BACKGROUND: According to new estimates, the health care sector will suffer a shortage of physicians in primary and specialty care. In this context, work engagement and burnout are two constructs that have gained attention recently. The aim of this study was to investigate how these constructs are related to work hour preference. METHOD: The present study was based on the baseline survey of the long-term study of physicians with different specialties, in which 1,001 physicians took part (response rate: 33.4%). Burnout was measured using the Copenhagen Burnout Inventory adapted for health care professionals; work engagement was assessed using the Utrecht Work Engagement scale. Data analyses included regression and mediation models. RESULTS: Overall, 297 out of 725 physicians were planning to cut down work hours. Several reasons - such as burnout - are discussed. According to multiple regression analyses desire to work less hours was significantly linked to all three dimensions of burnout (p < 0.001), as well as work engagement (p = 0.001). In addition, work engagement significantly mediated the relationship between the burnout dimensions on work hour reduction (patient-related: b = - 0.135, p < 0.001; work-related: b = - 0.190, p < 0.001; personal: b = - 0.133, p < 0.001 ). DISCUSSION: Physicians tending to reduce work hours exhibited different levels of work engagement as well as burnout (personal, patient- and work-related). Moreover, work engagement influenced the relationship between burnout and work hour reduction. Therefore, interventions that increase work engagement may positively impact negative effects of burnout on work hour changes.

BACKGROUND: The number of people living with dementia worldwide is increasing rapidly. Preventive approaches constitute a promising strategy to counter the dementia epidemic, and growing numbers of lifestyle interventions are conducted around the globe. Gender differences with respect to modifiable risk factors for dementia have been reported, however, little is known about gender-specific effectiveness of lifestyle trials against cognitive decline and dementia. A systematic review and meta-analysis was conducted to assess evidence on gender-specific design and effectiveness of randomized controlled trials against cognitive decline. METHODS: Systematic literature searches were conducted in MEDLINE, PsycINFO, Web of Science, Cochrane Central and ALOIS. Studies assessing global and/or domain-specific cognitive function in older adults free from dementia were eligible for the systematic review. We assessed between-group effect sizes using random-effects meta-analysis. Methodological quality of included studies was assessed using the Scottish Intercollegiate Guidelines Network (SIGN)-checklist. RESULTS: The systematic review and meta-analysis included 34 and 31 studies, respectively. Effects of lifestyle-interventions on global cognition were non-significant overall (g = .27; 95% CI: -.01; .56) and in male subsamples (g = -.05; 95% CI: -.55; .45), and small for female subsamples (g = .38; 95% CI: .05; .72). Small beneficial effects were found for memory (overall: g = .38; 95% CI = .17; .59). Stratified by gender, significant effects were observed only in women (g = .39; 95% CI = .13; .65; men: g = .37; 95% CI: .00; .73). Aspects of gender in study design and conduct were discussed in a small minority of studies. Comparable results were observed for executive function and verbal fluency. Methodological quality was deemed high in 17.6% of studies, acceptable and low quality in 52.9% and 29.4%, respectively. DISCUSSION: We found evidence for small differences in the effectiveness of lifestyle interventions on global cognition and memory in favor of women. However, small numbers of trials 1) targeting men and 2) reporting gender-specific results for older adults with mild cognitive impairment warrant further attention. Assessing differences in modifiable risk factors for dementia in men and women and systematically addressing aspects of gender in trial conduction and recruitment in future studies might increase knowledge on gender-specific effectiveness of lifestyle trials against cognitive decline.

BACKGROUND: Changes in everyday work with regard to working time models have reached the medical profession. The number of physicians working part-time is steadily increasing. At the same time, however, the population's need for care is also rising. This can reinforce the impending shortage of doctors in the future. The aim was to investigate differences in work-privacy conflict and burnout among physicians working full-time or part-time. METHOD: The present study includes data from a baseline survey of the long-term study of physicians with different medical backgrounds. The analysis focused on a sub-sample of 598 physicians (not self-employed). The two main outcomes under investigation-burnout and work-privacy conflict-were measured using the Copenhagen Burnout Inventory adapted for health care professionals, as well as the associated subscale of the Copenhagen Psychosocial Questionnaire (COPSOQ). Data analyses included descriptive statistics followed by regression models. RESULTS: Descriptive analyses show, that 31.8% of physicians are working part-time, whereas 68.2% are working full-time. The part-time subsample is significantly older, and female physicians are more likely to work part-time. With regard to workload and work-privacy conflict, significant differences between part-time and full-time physicians were only observed in terms of work-privacy-conflict. However, regression analysis underline the importance of possible confounding variables (such as medical setting) within the relationship between job size and job-related well-being. DISCUSSION: Differences in working hour arrangements (full-time or part-time work) are only accompanied by less work-privacy conflict. No differences with regard to burnout (patient-related, work-related or personal) could be obtained. Rather, the data suggests that other job-related variables may play a role and should be further investigated.

BACKGROUND: Online interventions can effectively improve depressive symptoms. They often include behavioral activation (BA) techniques, but research on the effects on behavioral activation is scarce. This study aims to examine short- and long-term effects of online interventions on behavioral activation in routine care. METHODS: This study is a secondary analysis of a pragmatic cluster-randomized controlled trial (@ktiv) with a sample of N = 647 GP patients with mild to moderate depression. The intervention group (IG) received treatment-as-usual (TAU) and adjunct access to an online intervention; the control group (CG) received TAU. BA was assessed in terms of the frequency and enjoyment of pleasant activities at baseline, after six weeks and after six months. Intention-to-treat analyses were performed via multilevel mixed linear regression. RESULTS: The frequency of pleasant activities was significantly higher in the IG than in the CG six months after baseline (t(1406) = 2.25, p = .024). The enjoyment of pleasant activities was significantly higher in the IG than in the CG both six weeks (t(1405) = 2.11, p = .035) and six months after baseline (t(1405) = 3.44, p = .001). Initial depressive symptoms significantly moderated the treatment effect on the enjoyment but not the frequency of pleasant activities. LIMITATIONS: BA measures have not been validated in a clinical context. CONCLUSIONS: GP patients with mild to moderate depressive symptoms profited from access to an online adjunct intervention in terms of improved behavioral activation. The findings emphasize the usefulness of online interventions as supportive options in mental health care.

OBJECTIVE: In this study, we aimed to analyze the association between new-incident-subjective memory complaints (SMC) and risk of subsequent dementia in a general population sample aged 75+ years. METHOD: Data were derived from follow-up (FUP) waves I-V of the population-based Leipzig Longitudinal Study of the Aged (LEILA75+). We used the Kaplan-Meier survival method to estimate dementia-free survival times of individuals with and without incident SMC and multivariable Cox proportional hazards regression to assess the association between incident SMC and risk of subsequent dementia, controlled for covariates. RESULTS: Of 443 non-demented individuals, 58 (13.1%) developed dementia during a subsequent 5.4-year follow-up period. Participants with incident SMC showed a significantly higher progression to dementia (18.5% vs. 10.0%; P=0.010) and a significantly shorter mean dementia-free survival time than those without (6.2 vs. 6.8 years; P=0.008). The association between incident SMC and risk of subsequent dementia remained significant in the multivariable Cox analysis (adjusted hazard ratio=1.8; P=0.028). CONCLUSION: Our findings suggest higher progression to dementia and shorter dementia-free survival in older individuals with incident SMC. These findings support the notion that such subjective complaints should be taken seriously in clinical practice as possible early indicators of incipient dementia.

BACKGROUND: Due to the demographic development depressive disorders in old age are becoming a central and urgent healthcare challenge. OBJECTIVES: The article reviews effective approaches towards treatment of depression in the elderly. METHODS: A literature review of complex interventions improving depression care was carried out. RESULTS: Robust evidence exists for the use of collaborative care models which incorporate collaboration between mental health and medical providers in the primary care setting (e.g. general practitioners and specialists), regular monitoring, case management, and evidence-based treatment. Staged treatment approaches seem to be appropriate by which initially use treatment strategies of low intensity. For patients with limited mobility, home-based approaches have proven to be particularly practical and effective. CONCLUSION: Multidisciplinary and multimodal treatment approaches represent an effective and efficient way of healthcare provision for late life depression. In Germany, only few initiatives inspired by successful international models have so far been identified.

BACKGROUND: The fear of a shortage of physicians in some regions of Germany is growing. A drain of physicians into non-clinical activities is being discussed as a possible reason. To counteract this drain the extent of physicians' thinking about leaving patient care and the corresponding reasons need to be elucidated. METHODS: All physicians upto 40 years of age and registered with the State Chamber of Physicians of Saxony (n=5,956) received a paper-pencil questionnaire inquiring about socio-demographics, job satisfaction, thinking about leaving patient care, and corresponding reasons. Reponse rate was 40% (n=2 357). RESULTS: Nearly a quarter of the physicians working in patient care thought about leaving patient care. Practicing in a hospital and having children were significantly associated with think-ing about leaving patient care. The main reasons were poor compatibility of profession and family, high burden due to shifts, poor compatibility of profession and private interests, high work load, and frequent overtime hours. CONCLUSIONS: Development and implementation of measures preventing especially long-term or permanent leave is crucial. Approaches enabling physicians to reconcile work and family play a special role.

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.

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.

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.

This paper reviews the concepts, evidence and implications regarding mental health at the workplace. The theoretical background with the most common theories (e.g. effort-reward imbalance model and job-demand control model) are briefly reviewed and findings from systematic reviews and from a meta-analysis regarding psychosocial factors at the workplace and common mental disorders, which indicate that psychosocial factors increase the risk of mental disorder are outlined. Implications for primary prevention as well as early intervention and treatment following a stepped care model including a variety of agents from different backgrounds are discussed. Implications to enhance research in the field are outlined.

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.

Depression in old age is common and has severe consequences. The paper reviews the most recent results of population-based and primary care-based studies reporting the prevalence, course and risk factors for depression in old age. Consequences of late life depression for the individual and for the society in terms of costs of illness are outlined. Studies of health service utilization and costs showed homogeneously that healthcare costs for depressive elderly individuals are one third higher compared to non-depressive individuals even though most do not receive depression-specific treatment. Late life depression is underrecognized and undertreated and data from Germany are rare. Improvement strategies, such as collaborative care models are discussed; however, adaptation and implementation to the German context are still pending. Future demographic changes will facilitate mental health service research into late life depression.

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.

BACKGROUND: Data on prevalence of chronic diseases are important for planning health care services. Such prevalence data are mostly based on patient self-reports, claims data, or other research data-with limited validity and reliability partially due to their cross-sectional character. Currently, only claims data of statutory health insurance offer longitudinal information. In Germany, these data show a loss of diagnoses of chronic health conditions over time. This study investigated whether there is a similar tendency of loss in the documentation of chronic diseases in data specifically collected for a longitudinal cohort study by general practitioners. In addition, the explanatory power of patient or GP characteristics regarding these losses is investigated. PATIENTS AND METHODS: A total of 3,327 patients aged 75 years and older were recruited for the German Study on Ageing, Cognition and Dementia in Primary Care Patients (AgeCoDe). For 1,765 patients, GP diagnoses of four chronic conditions at three time points were available for a total period of 4.5 years. In order to explain the loss of chronic diagnoses, a multilevel mixed-effects logistic regression was performed. RESULTS: Over the course of 4.5 years, 18.6% of the diagnoses of diabetes mellitus, 34.5% of the diagnoses of coronary heart disease, and 44.9% of the diagnoses of stroke disappeared in the GP documentation for the longitudinal study. The diagnosis of coronary heart disease was less often lost in men than in women. The risk of losing the diagnosis of diabetes was higher in patients who were well known by the GP for a long time. An essential part of the variance of the losses can be explained by practice (owner) effects. CONCLUSION: Data on morbidity collected in epidemiological studies and reported by physicians should always be checked for validity and reliability. Appropriate options (e.g., an investigator collecting the data directly in the field or the comparison of the data with health insurance companies' claims data) are presented and discussed.

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.

BACKGROUND: Recent studies examined the role of psychiatric comorbidity in the process of rehabilitation in patients undergoing herniated disc surgery. These patients suffer from physical and psychosocial complaints or symptoms, which impact their everyday life negatively and the success of rehabilitation potentially. The objectives of this study are (1) to examine the quality of life (QoL) in disc surgery patients and to compare the findings with reference data from the general German population, and (2) to investigate the impact of psychiatric comorbidity on QoL of patients undergoing herniated disc surgery. METHODS: This study consists of 305 patients aged between 18 and 55 years who took part in face-to-face interviews during their hospital stay. Psychiatric comorbidity was assessed with the Composite International Diagnostic Interview (CIDI-DIA-X). By means of the 36-Item Short-Form Health Survey (SF-36), QoL was assessed in patients undergoing herniated disc surgery with and without psychiatric comorbidity. These findings were compared with the QoL of a representative sample of the general German population. RESULTS: Compared with the general population, QoL in patients with herniated disc surgery was lower in all domains of the SF-36. Psychiatric comorbidity impacts the QoL in patients with herniated disc surgery in all SF-36 domains except "physical function". The patients with psychiatric comorbidity showed significantly lower levels of QoL in the domains "bodily pain", "vitality", "social function", "role emotional", and "mental health". CONCLUSIONS: Psychiatric comorbidity has a substantial adverse effect on QoL in patients undergoing disc surgery. Therefore, it will be necessary to diagnose psychiatric comorbidities at an early stage and to include psychosocial interventions in the treatment of herniated disc patients aimed at improving deficits in psychosocial functioning and QoL.
