THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 33:100687. [PMID: 37181529 PMCID: PMC10166998 DOI: 10.1016/j.lanwpc.2023.100687] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 12/11/2022] [Accepted: 12/24/2022] [Indexed: 01/15/2023]
Abstract
Background Post-stroke cognitive impairment (PSCI) is a common sequela after stroke. China has a large population of stroke survivors, but a large-scale survey on the incidence and risk factors for PSCI has not been undertaken. We aimed to calculate the incidence and risk factors for vascular cognitive symptoms among first-ever stroke survivors in China through a multicenter cross-sectional study. Methods From May 1, 2019 to November 30, 2019, patients with a clinical diagnosis of first-ever ischemic stroke were recruited from 563 hospitalized-based stroke center networks in 30 provinces of China. Cognitive impairment was measured by 5-min National Institute of Neurological Disease and Stroke-Canadian Stroke Network (NINDS-CSN) at 3-6 months after the indexed stroke. Stepwise multivariate regression and stratified analysis were performed to assess the association between PSCI and demographic variables. Findings A total of 24,055 first-ever ischemic stroke patients were enrolled, with an average age of 70.25 ± 9.88 years. The incidence of PSCI as per the 5-min NINDS-CSN was 78.7%. Age ≥75 years old (OR: 1.887, 95%CI: 1.391-2.559), western regional residence (OR: 1.620, 95%CI: 1.411-1.860) and lower education level were associated with increased PSCI risk. Hypertension might be related to non-PSCI (OR: 0.832, 95%CI: 0.779-0.888). For patients under 45 years old, unemployment was an independent risk factor for PSCI (OR: 6.097, 95%CI: 1.385-26.830). For patients who were residents of the southern region (OR: 1.490, 95%CI: 1.185-1.873) and non-manual workers (OR: 2.122, 95%CI: 1.188-3.792), diabetes was related to PSCI. Interpretation PSCI is common in Chinese patients with first-ever stroke, and many risk factors are related to the occurrence of PSCI.

Abstract
Stress has deleterious effects on brain health and yet, the prognostic value of psychosocial stress regarding the most common types of dementias, including Alzheimer disease, is still unclear. The primary aim of this systematic review was to explore the association between psychosocial stress and late onset dementia. We classified 24articles from Medline, PsycINFO, CINAHL, and Web of Science, as pertaining toxic categories of psychosocial and trauma-related stress (low socio-economic status [SES] related inequalities, marital status, posttraumatic stress disorder, work stress, "vital exhaustion" [VE], and, combined stressors). Using the Quality of Prognosis Studies in Systematic Reviews tool, we judged the quality of evidence to be low. This systematic review provided some non-robust, yet suggestive evidence that the above psychosocial types of stress are associated with increased risk of dementia in later life. Future robust, longitudinal studies with repeated validated measures of psychosocial stress and dementiaare required to strengthen or refute these findings.

Abstract
Objectives: There is strong evidence about the association between low socioeconomic status (SES) and higher risk of dementia. However, it has not been conveniently addressed so far the role of SES on the incidence of mild cognitive impairment (MCI). This study examines the impact of individual and neighbourhood dimensions of SES, as well as their interaction, on the risk of developing MCI in a sample of older adults.Method: Data from the Vallecas Project cohort, an ongoing community-based longitudinal study for early detection of cognitive impairment and dementia, were used to build two indices of SES namely individual and neighbourhood, as well as a global SES as a combination of both, and to investigate their effects on MCI conversion by means of a multivariate-adjusted Cox proportional hazard model.Results: A total of 1180 participants aged 70 years and older were enrolled in this study. Of these, 199 cases of MCI (16.9%) were diagnosed at any point of the follow-up. The individual and neighbourhood dimensions of SES played different roles in the dynamics of the MCI occurrence through aging. Most importantly, the risk of developing MCI was almost double for lower SES quartiles when compared to the highest one.Conclusion: The incidence of MCI in older adults was related to both individual characteristics and socioeconomic context. Public health strategies should be holistic and focus not only on promoting the classical individual preventive measures, but also on reducing social inequalities to foster healthy aging and reduce dementia burden.

Abstract
BACKGROUND There remains a lack of information and understanding of the prevalence and incidence of Alzheimer's disease and related dementia in Indigenous populations. Little evidence available suggests that Indigenous peoples may have disproportionately high rates of Alzheimer's disease and related dementia (ADRD). OBJECTIVE Given this information, this study systematically explores what risk factors may be associated with ADRD in Indigenous populations. METHODS A search of all published literature was conducted in October 2016, March 2018, and July 2019 using Medline, Embase, and PsychINFO. Subject headings explored were inclusive of all terms related to Indigenous persons, dementia, and risk. All relevant words, phrases, and combinations were used. To be included in this systematic review, articles had to display an association of a risk factor and ADRD. Only studies that reported a quantifiable measure of risk, involved human subjects, and were published in English were included. RESULTS Of 237 articles originally identified through database searches, 45 were duplicates and 179 did not meet a priori inclusion criteria, resulting in 13 studies eligible for inclusion in this systematic review. CONCLUSION The large number of potentially modifiable risk factors reported relative to non-modifiable risk factors illustrates the importance of socioeconomic context in the pathogenesis of ADRD in Indigenous populations. The tendency to prioritize genetic over social explanations when encountering disproportionately high disease rates in Indigenous populations can distract from modifiable proximal, intermediate, and distal determinants of health.

Chao LL. The Prevalence of Mild Cognitive Impairment in a Convenience Sample of 202 Gulf War Veterans. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17197158.

Abstract
Gulf War Illness (GWI) is a chronic, multisymptom disorder estimated to affect approximately 25–32% of Gulf War veterans (GWVs). Cognitive dysfunction is a common symptom of GWI. On the continuum of cognitive decline, mild cognitive impairment (MCI) is conceptualized as a transitional phase between normal aging and dementia. Individuals with MCI exhibit cognitive decline but have relatively spared activities of daily function and do not meet criteria for dementia. The current study sought to investigate the prevalence of MCI in a convenience sample of 202 GWVs (median age: 52 years; 18% female). Twelve percent of the sample (median age: 48 years) had MCI according to an actuarial neuropsychological criterion, a rate materially higher than expected for this age group. GWVs with MCI also had a smaller hippocampal volume and a thinner parietal cortex, higher rates of current posttraumatic stress disorder and major depressive disorder compared to GWVs without MCI. Because people with MCI are more likely to progress to dementia compared to those with normal cognition, these results may portend future higher rates of dementia among deployed GWVs.

Abstract
OBJECTIVE Investigate whether socioeconomic status (SES) was related to brain volume in aging related regions, and if so, determine whether this relationship was mediated by lifestyle factors that are known to associate with risk of dementia in a population-based sample of community dwelling middle-aged adults. METHODS We studied 645 (41% black) participants (mean age 55.3±3.5) from the Coronary Artery Risk Development in Young Adults (CARDIA) study who underwent brain magnetic resonance imaging. SES was operationalized as a composite measure of annual income and years of education. Gray matter volume was estimated within the insular cortex, thalamus, cingulate, frontal, inferior parietal, and lateral temporal cortex. These regions are vulnerable to age-related atrophy captured by the Spatial Pattern of Atrophy for Recognition of Brain Aging (SPARE-BA) index. Lifestyle factors of interest included physical activity, cognitive activity (e.g. book/newspaper reading), smoking status, alcohol consumption, and diet. Multivariable linear regressions tested the association between SES and brain volume. Sobel mediation analyses determined if this association was mediated by lifestyle factors. All models were age, sex, and race adjusted. RESULTS Higher SES was positively associated with brain volume (β = .109 SE = .039; p < .01) and smoking status significantly mediated this relationship (z = 2.57). With respect to brain volume, smoking accounted for 27% of the variance (β = -.179 SE = .065; p < .01) that was previously attributed to SES. CONCLUSION Targeting smoking cessation could be an efficacious means to reduce the health disparity of low SES on brain volume and may decrease vulnerability for dementia.

Abstract
OBJECTIVE Matrix metalloproteinases (MMPs) may play a role in the pathophysiology of neurodegenerative disease and hernia formation. This retrospective cohort study was designed to assess whether there is an association between hernia and the risk of dementia. MATERIALS AND METHODS Patients (≥45 years) with hernias were identified between 2000 and 2008 from a longitudinal claims data of one million beneficiaries from Taiwan's National Health Insurance program. A control group of patients with comparable distributions of sex, age, socioeconomic status, urbanization, and medical comorbidities without hernia were chosen for matching in a ratio of 1:1. Patients previously diagnosed with dementia were excluded. Follow-up ended on December 31, 2013. Incidence rate of dementia was compared between patients with hernias and those without. Cox proportional hazards models were used to estimate hazards relative to those of the control group. RESULTS After matching, there were 4,784 hernia and 4,784 nonhernia patients. Hernia patients showed a higher incidence rate and hazard ratio of dementia than those in nonhernia group (8.82 vs. 7.19/1,000 person-years; adjusted hazard ratio [aHR], 1.24; 95% CI, 1.07 to 1.45; p < .01). Advanced age (p < .0001), hypertension (p = .0139), head injury (p = .0003), and stroke (p = .041) were found to be risk factors for dementia, while patients with high socioeconomic status (p < .01) and history of coronary artery disease (p = .0292) were unlikely to develop dementia in our cohort study. CONCLUSION Patients with hernias were associated with a higher incidence of dementia than those without. Our finding should be validated in further prospective studies with larger samples.

Abstract
INTRODUCTION Cognitive impairment (CI) in Multiple Sclerosis (MS) has progressively regained clinical and research interest and is currently recognized as a debilitating and burdensome problem for these patients. Studying risk and protecting factors that may influence the development and course of CI is currently an area of increasing interest, due to the potential for preventive strategies. Areas covered: In this narrative review the authors briefly addressed the physiopathologic basis, assessment and management of CI in MS and then focused on identifying modifiable and not modifiable risk factors for CI in MS, providing an overview of the current knowledge in the field and indicating avenues for future research. Expert opinion: Improving our understanding of potentially modifiable environmental and lifestyle risk factors or protective factors for CI is important in order to prompt preventive strategies and orient patient counselling and clinical management. To this aim, we need to enhance the current level of evidence linking lifestyle factors to cognition and evaluate some factors that were only preliminary addressed in research. Moreover, we need to explore the role of each factor into the subject cognitive outcome, next to the possible interactions between different environmental factors as well as between environmental and genetic factors.

Abstract
Conduct of research is an essential tool for the evaluation and improvement of health services. In Israel, research on persons with dementia is very limited, with the largest portion of such research involving a few surveys and examining risk factors for dementia. Very few studies describe clinical research, and those that do either include participants at early stages of dementia, or rely completely on caregivers' perceptions and experiences, often without reference to any individual with dementia. This dearth of research is due, to a substantial extent, to Ministry of Health regulations which do not permit family proxy consent for research involving persons with dementia. Alternative models for regulation of consent for research exist in other countries, including the U.S., and these allow for proxy consent under certain conditions. This paper presents such a model and its underlying ethical principles. It contends that the current state of affairs, which stands in the way of clinical research concerning persons with advanced dementia, is contrary to the interests of such persons, their caregivers, and Israeli society. Therefore, this paper calls for a change in the present regulations and/or law in the cause of advancing knowledge and improving care for persons with dementia.

Abstract
AIM In Japan, with the largest percentage of population aged 65 years or over, a dementia strategy is needed not only from a medical perspective, but also from a social policy viewpoint. This study aimed to verify the association between socioeconomic factors and cognitive decline among Japanese elderly people. METHODS Cognitive decline was assessed over a 15-year follow-up period using memory tests or through identifying missing/proxy responses to survey questions due to cognitive dysfunction. I analysed 1886 men and 2102 women in Japan, using competing risk models for cognitive decline, to consider survival effects. Survival effects have not been considered so far although those who live longer may be more likely to experience cognitive decline. RESULTS Men with higher income had a lower risk of cognitive decline (sub-hazard ratio [SHR]: 0.997, 95% confidence interval (CI): 0.995-0.999). Women with higher education had a lower risk of cognitive decline: 8 to 9 years (SHR: 0.646, 95% CI: 0.457-0.914) and ≥12 years (SHR: 0.360, 95% CI: 0.164-0.794) than women with 0 to 7 years of education. CONCLUSION This study suggests that cognitive decline among the elderly Japanese population is associated with socioeconomic factors, such as income and education, even after taking survival effects into account.

Abstract
Aim of the paper is to quantify effects of socioeconomic factors on Alzheimer's Disease Mortality in the Slovak Republic. We applied potential gains in life expectancy (PGLE) method to measure the impact of elimination of Alzheimer's disease on life expectance in Slovak regions. PGLE is based on life table adjustment according to elimination of mortality caused by specific diagnosis. Our dataset consists of all deceased from Slovak Republic from 2001 to 2015. We analyse the impact of unemployment rate, GDP per capita, average wage, and education on life expectance in Slovak regions. To estimate that impact, ordinary least squares (OLS) is applied. According to our model, gross domestic product, average wage, and education influence mortality caused by Alzheimer's disease.

Abstract
OBJECTIVE To analyze the prevalence of different degrees vascular cognitive impairment (VCI) in stroke and the characteristics of demography distribution in Inner Mongolia. In order to provide reference data and theoretical guidance for the prevention and treatment of VCI after stroke in the area. METHODS Stratified multi-stage random sampling was used to extract six regions of Inner Mongolia as the first sampling cluster; and then the corresponding banners (counties) were selected randomly as the secondary sampling cluster; according to the number of patient required to investigation, the corresponding number of communities was randomly selected from the secondary sampling cluster. According to the diagnostic criteria of 'Guidelines for the diagnosis and treatment of vascular cognitive impairment' and National Institute of Neurological Disorders and Stroke convened an International Workshop with support from the Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN), we screened all stroke patients aged 45 or older from each community, a total of 444 patients participated in the questionnaire and various scale assessments. RESULTS The prevalence of VCI, vascular cognitive impairment no dementia and vascular dementia was 80.41%, 34.46% and 45.95% respectively. The prevalence of VCI in stroke was significantly different in different nationality, age and education level (P < 0.05), and there was no significant difference in gender, occupation, marital status and family structure (P > 0.05). CONCLUSION The prevalence of VCI after stroke was higher in Inner Mongolia, and VCI had a relatively high morbidity in old age people and person with less education in Chinese Han population.

[Influence of social characteristics on the duration of treatment, severity of the disease and social support of patients in a surgical intensive care unit]. Anaesthesist 2018; 67:336-342. [PMID: 29564474 DOI: 10.1007/s00101-018-0430-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Revised: 01/10/2018] [Accepted: 03/02/2018] [Indexed: 11/29/2022]
Abstract
BACKGROUND In critical illnesses low socioeconomic status (SES) is associated with higher morbidity and mortality. In addition to the SES, further factors at an individual level (e.g., sex, health insurance status and place of residence) may influence the severity of illness and medical treatment. We investigated these additional parameters in a secondary analysis of the ECSSTASI data. METHODS Within the framework of the ECSSTASI study, 996 patients were recruited from a surgical intensive care unit. We examined the influence of sex, insurance status and place of residence on health-related behavior, disease severity, duration of intensive care and ventilation (28 ventilator-free days score, 28-VFDS) and social support by the next of kin. Multivariate-adjusted logistic regression analyses were carried out and odds ratios (OR) are presented with corresponding 95% confidence intervals. RESULTS Among patients admitted to the intensive care unit, the disease severity (SOFA score >5) was significantly lower in women than in men (OR 0.62 [0.45-0.87]). Increasing size of the patient's town of residence was associated with a significantly shorter duration of treatment on the intensive care unit (OR 0.54 [0.32-0.91]). An increasing number of persons in the household was associated with a significantly increased risk of being ventilated longer compared to 1‑person households (p = 0.028). Patients with private insurance (OR 1.87 [1.28-2.70]), patients from households with ≥4 persons (OR 1.92 [1.1-3.33]) and patients without German citizenship (OR 2.56 [1.39-4.55]) were visited significantly more often by next of kin. CONCLUSION In addition to the SES, sociodemographic characteristics of the individual patient are associated with the course of treatment in intensive care medicine. The extent of social support by the next of kin depends on intercultural and individual patient characteristics. An increasing size of the town of residence and private health insurance status positively influence intensive care outcomes. In order to evaluate these data, further epidemiological studies in intensive care medicine are necessary.

Abstract
OBJECTIVE The aim of the study was to examine interactive relations of race and socioeconomic status (SES) to magnetic resonance imaging (MRI)-assessed global brain outcomes with previously demonstrated prognostic significance for stroke, dementia, and mortality. METHODS Participants were 147 African Americans (AAs) and whites (ages 33-71 years; 43% AA; 56% female; 26% below poverty) in the Healthy Aging in Neighborhoods of Diversity across the Life Span SCAN substudy. Cranial MRI was conducted using a 3.0 T unit. White matter (WM) lesion volumes and total brain, gray matter, and WM volumes were computed. An SES composite was derived from education and poverty status. RESULTS Significant interactions of race and SES were observed for WM lesion volume (b = 1.38; η = 0.036; p = .028), total brain (b = 86.72; η = 0.042; p < .001), gray matter (b = 40.16; η = 0.032; p = .003), and WM (b = 46.56; η = 0.050; p < .001). AA participants with low SES exhibited significantly greater WM lesion volumes than white participants with low SES. White participants with higher SES had greater brain volumes than all other groups (albeit within normal range). CONCLUSIONS Low SES was associated with greater WM pathology-a marker for increased stroke risk-in AAs. Higher SES was associated with greater total brain volume-a putative global indicator of brain health and predictor of mortality-in whites. Findings may reflect environmental and interpersonal stressors encountered by AAs and those of lower SES and could relate to disproportionate rates of stroke, dementia, and mortality.

Abstract
BACKGROUND The relationship of obesity with risk for dementia is complex and may change with age. OBJECTIVE To analyze the relationship between measures of obesity at age 40-65 and dementia prevalence in survivors 36 years later. METHODS Obesity-related measures of triceps and subscapular skinfold thickness were assessed in 1963 in n = 9,760 men aged 40-65 participating in the Israel Ischemic Heart Disease study. Cognitive evaluation and assessment of dementia prevalence were performed in n = 1,643 participants of the original cohort who survived until 1999/2000 (age ≥76 years) and had anthropometric measures in 1963. RESULTS Age-adjusted prevalence of dementia in survivors in 1999/2000 by baseline triceps skinfold quintile was 20.5%, 21.2%, 17.6%, 15.6%, and 14.5%, respectively, from lowest to highest (p = 0.006 in trend test). Using logistic regression, a 6-mm increment of triceps skinfold was associated with an age and BMI-adjusted odds ratio of 0.81 (95% CI, 0.70-0.94) for dementia prevalence among survivors. Age-adjusted risk for dementia by subscapular skinfold quintile demonstrated 20.5%, 17.1%, 15.7%, 19.4%, and 18.1%, respectively, in groups of subjects by subscapular skinfold quintile from lowest to highest (p = 0.6 in trend test). CONCLUSIONS Lower triceps skinfold at age 40-65, reflecting diminished peripheral fat, was associated with higher dementia prevalence in late life, potentially suggesting a protective role of peripheral fat to brain health.

Abstract
Research addressing social class and dementia has largely focused on measures of socioeconomic status as causal risk factors for dementia and in observed differences in diagnosis, treatment and care. This large body of work has produced important insights but also contains numerous problems and weaknesses. Research needs to take account of the ways in which ageing and social class have been transformed in tandem with the economic, social and cultural coordinates of late modernity. These changes have particular consequences for individual identities and social relations. With this in mind this article adopts a critical gaze on research that considers interactions between dementia and social class in three key areas: (i) epidemiological approaches to inequalities in risk (ii) the role of social class in diagnosis and treatment and (iii) class in the framing of care and access to care. Following this, the article considers studies of dementia and social class that focus on lay understandings and biographical accounts. Sociological insights in this field come from the view that dementia and social class are embedded in social relations. Thus, forms of distinction based on class relations may still play an important role in the lived experience of dementia.

Abstract
Low socioeconomic status (SES) has been linked to a higher incidence of dementia. Less is known about the association between SES and mortality in persons with dementia. We studied this association in a prospective cohort of 15,558 patients in the Netherlands between 2000 and 2010. SES was measured using disposable household income and divided in tertiles. Overall, there was a negative relationship between SES and mortality in both sexes and both settings of care. For men who visited a day clinic, the 5-year mortality rate was 74% among those in the lowest tertile of SES and 57% among those in the highest; for women, the rates were 60% and 50%, respectively. The differences in median survival times between persons in the lower and upper tertiles of SES were 260 days for men and 300 days for women. For men who were admitted to the hospital, the 5-year mortality rate was 89% among those in the lowest tertile of SES and 86% among those in the highest; for women, the rates were 83% and 77%, respectively. The differences in median survival times between persons in the lower and upper tertiles of SES were 80 days for men and 130 days for women. Among patients who visited a day clinic, for patients in the lowest tertile of SES versus those in the highest, the adjusted hazard ratio was 1.41 (95% confidence interval: 1.26, 1.57); for those admitted to the hospital, it was 1.14 (95% confidence interval: 1.07, 1.20). In summary, lower SES was associated with a higher mortality risk in both men and women with dementia. The results of the present study should raise awareness in clinicians and caregivers about the unfavorable prognosis in the most deprived patients.

Abstract
BACKGROUND Dementia affects 15% of Canadians 65 and older, and the prevalence is expected to double over the next two decades. Low socioeconomic status (SES) can increase the risk of Alzheimer's disease (AD) and the precursor mild cognitive impairment (MCI), but it is unknown what the relationship of SES is on initial clinical presentation to a memory disorders clinic. METHODS Data from 127 AD and 135 MCI patients who presented to our Memory Disorders Clinic from 2004 to 2013 were analyzed retrospectively. We examined the relationship between SES (measured using Hollingshead two-factor index) and (1) diagnosis of either AD or MCI; (2) age when first presented to clinic; (3) objective cognitive tests to indicate clinical severity; and (4) the use of cognitive enhancers, medication for treating mild-to-moderate AD patients. RESULTS AD patients had lower SES than MCI patients (p < 0.001, r = 0.232). Lower SES was associated with a greater age at initial time of diagnosis (χ2 = 11.5, p = 0.001). In MCI patients, higher SES individuals outperformed lower SES individuals on the BNA after correcting for the effect of age (p = 0.004). Lower SES was also associated with decreased use of cognitive enhancers in AD patients (p < 0.001, r = 0.842). CONCLUSION Individuals with lower SES come into memory clinic later when the disease has progressed to dementia, while higher SES individuals present earlier when the disease is still in its MCI stage. There were more higher SES individuals who presented to our memory clinic. Higher SES is associated with better cognitive functioning and increased use of cognitive enhancers. The health policy implication is that we need to better engage economically disadvantaged individuals, perhaps at the primary care level.

Abstract
Evidence suggests that education protects from dementia by enhancing cognitive reserve. However, this may be influenced by several socio-demographic factors. Rising numbers of dementia in India, high levels of illiteracy and heterogeneity in socio-demographic factors provide an opportunity to explore this relationship. OBJECTIVE To study the association between education and age at dementia onset, in relation to socio-demographic factors. METHODS Association between age at dementia onset and literacy was studied in relationship to potential confounding factors such as gender, bilingualism, place of dwelling, occupation, vascular risk factors, stroke, family history of dementia and dementia subtypes. RESULTS Case records of 648 dementia patients diagnosed in a specialist clinic in a University hospital in Hyderabad, India were examined. All patients were prospectively enrolled as part of an ongoing longitudinal project that aims to evaluate dementia subjects with detailed clinical, etiological, imaging, and follow-up studies. Of the 648 patients, 98 (15.1%) were illiterate. More than half of illiterate skilled workers were engaged in crafts and skilled agriculture unlike literates who were in trade or clerical jobs. Mean age at onset in illiterates was 60.1 years and in literates 64.5 years (p=0.0002). Factors independently associated with age at dementia onset were bilingualism, rural dwelling and stroke, but not education. CONCLUSION Our study demonstrates that in India, rural dwelling, bilingualism, stroke and occupation modify the relationship between education and dementia.

Abstract
Previous studies have not shown a survival advantage for smoking reduction. The authors assessed survival and life expectancy according to changes in smoking intensity in a cohort of Israeli working men. Baseline smokers recruited in 1963 were reassessed in 1965 (n = 4,633; mean age, 51 years) and followed up prospectively for mortality through 2005. Smoking intensity at both time points was self-reported and categorized as none, 1-10, 11-20, and ≥21 cigarettes per day. Change between smoking categories was noted, and participants were classified as increased (8%), maintained (65%), reduced (17%), or quit (10%) smoking. During a median follow-up of 26 (quartiles 1-3: 16-35) years, 87% of participants died. Changes in intensity were associated with survival. In multivariable-adjusted models, the hazard ratios for mortality were 1.14 (95% confidence interval (CI): 0.99, 1.32) among increasers, 0.85 (95% CI: 0.77, 0.95) among reducers, and 0.78 (95% CI: 0.69, 0.89) among quitters, compared with maintainers. Inversely, the adjusted odds ratios of surviving to age 80 years were 0.77 (95% CI: 0.60, 0.98), 1.22 (95% CI: 1.01, 1.47), and 1.33 (95% CI: 1.07, 1.66), respectively. The survival benefit associated with smoking reduction was mostly evident among heavy smokers and for cardiovascular disease mortality. These results suggest that decreasing smoking intensity should be considered as a risk-reduction strategy for heavy smokers who cannot quit abruptly.

Abstract
Holocaust and Nazi concentration camp survivors were subjects to prolonged and multi-dimensional trauma and stress. The aim of the present study was to assess the association between exposure to such trauma during late adolescence and adulthood with dementia at old age. In 1963, approximately 10,000 male civil servants aged 40-71 participated in the Israel Ischemic Heart Disease (IIHD) study. Of them, 691 reported having survived Nazi concentration camps [concentration Camp Survivors (CCS)]. Additional 2316 participants were holocaust survivors but not concentration camp survivors (HSNCC) and 1688 were born in European countries but not exposed to the Holocaust (NH). Dementia was assessed in 1999-2000, over three decades later, in 1889 survivors of the original IIHD cohort; 139 of whom were CCS, 435 were HSNCC, and 236 were NH. Dementia prevalence was 11.5% in CCS, 12.6% in HSNCC, and 15.7% in NH. The odds ratio of dementia prevalence, estimated by age adjusted logistic regression, for CCS as compared to HSNCC was 0.97 (95% CI: 0.53-1.77), approximate Z = -0.10; p = 0.92. Further adjustment for socioeconomic status, diabetes mellitus, and other co-morbidity at midlife (coronary heart disease, lung, and kidney disease), and height did not change the results substantially. Thus, in subjects who survived until old age, late adolescence and adulthood exposure to extreme stress, as reflected by experiencing holocaust and Nazi concentration camps, was not associated with increased prevalence of dementia. Individuals who survived concentration camps and then lived into old age may carry survival advantages that are associated with protection from dementia and mortality.

Abstract
Background Low socioeconomic status (SES) is associated with increased mortality from cardiovascular disease, cancer and trauma. However, individual-level prospective data on SES in relation to health outcomes among critically ill patients admitted to intensive care units (ICU) are unavailable. Methods In a cohort of 1,006 patients at a 24-bed surgical ICU of an academic tertiary care facility in Germany, we examined levels of SES in relation to disease severity at admission, time period of mechanical ventilation, length of stay and frequency of phone calls and visits by next-of-kin. Findings Patients with low SES had higher risk for Sequential Organ Failure Assessment (SOFA) score greater or equal to 5 [multivariate-adjusted odds ratio (OR) 1.49; 95% confidence interval (CI) 0.95–2.33; p = 0.029] and a trend for higher risk for Simplified Acute Physiology Score (SAPS II) greater or equal to 31 (OR 1.28; 95% CI 0.80–2.05; p = 0.086) at admission as compared with patients with high SES. When compared with men with high SES, those with low SES had greater risk for ICU treatment ≥5 days (multivariate-adjusted OR 1.99; 95% CI 1.06–3.74; p = 0.036) and showed a trend for a low number of visits from next-of-kin (<0.5 visits per day) (OR 1.85; 95% CI 0.79–4.30; p = 0.054). In women such associations could not be demonstrated. Interpretation Socioeconomic status is inversely related to severity of disease at admission and to length of stay in ICU, and positively associated with the level of care by next-of-kin. Whether relations differ by gender requires further examination.

Abstract
BACKGROUND/AIMS Cognitive decline in the elderly is an early predictor of dementia. The apolipoprotein E (APOE) ε4 allele is considered an important genetic determinant of Alzheimer's disease (AD), and strongly suspected to play a role in cognitive variation. However, its effects upon predicting the progression of cognitive decline more generally remain unclear. Our aim was to explore the role of APOE ε4 in longitudinal cognitive decline, considering sociodemographics, vascular disease, and lipid profile. METHODS We chose a nested case-control design, and prospectively collected demographic and clinical data, determined APOE genotypes, and obtained follow-up information on cognitive variation (measured by a spectrum of cognitive tests) for 3 years. Cognitive decline was predefined as an increase in Clinical Dementia Rating Scale class, or at least a 4-point decrease (>1 SD) in MMSE, between baseline and follow-ups. RESULTS Among 600 follow-up subjects with mild cognitive impairment and aged 65 years or older, 114 pairs of cognitive decline and stable subjects were identified and matched for sex, age, and educational level in a 1:1 ratio. The APOE ε4 frequency in the cognitive decline group was significantly higher than that in the stable group (p < 0.05), while the APOE ε2 and ε3 prevalence in the cognitive decline group did not differ significantly from that in controls (p > 0.05). At the first follow-up, modest but significant declines only in the memory domain were associated with APOE ε4. At the last follow-up, significant associations were noted between APOE ε4 and cognitive decline from 5 of the 6 cognitive outcomes, which included story recall, memory, spatial recognition, naming, and sustained attention. Conditional logistic regression showed that the presence of APOE ε4 was significantly associated with the cognitive decline group, as compared to the stable group, adjusting for vascular diseases and lipid profile. CONCLUSIONS APOE ε4 offered information on the risk of cognitive decline in this longitudinal study, and may exert detectable effects early in a long prodromal AD trajectory.

Abstract
There have been few investigations of the link between changes in life-course socioeconomic position (SEP) and cognitive decline or incidence of dementia. The authors examined the impact of changes in life-course SEP on incidence of dementia and cognitive impairment but not dementia (CIND) over a decade of follow-up. Participants of Mexican origin (n = 1,789) were members of the Sacramento Area Latino Study on Aging cohort. Incidence of dementia/CIND was ascertained by using standard diagnostic criteria. SEP indicators at 3 life stages (childhood, adulthood, and midlife) were used to derive a measure of cumulative SEP (range, 0 to 8) and SEP mobility. Nearly 24% of the sample maintained a low SEP throughout life. Hazard ratios and 95% confidence intervals were computed from Cox proportional hazards regression models. In fully adjusted models, participants with a continuously high SEP had lower hazard ratios for dementia/CIND compared with those with a continuously low SEP at all 3 life stages (hazard ratio = 0.49, 95% confidence interval: 0.24, 0.98; P = 0.04). In age-adjusted models, participants experienced a 16% greater hazard of dementia/CIND with every 1-unit increase in cumulative SEP disadvantage across the life course (hazard ratio = 1.16, 95% confidence interval: 1.01, 1.33; P = 0.04). Early exposures to social disadvantage may increase the risk of late-life dementia.

Abstract
OBJECTIVES to compare the mortality rates of elderly demented and nondemented subjects and the differential association of midlife risk factors with mortality according to dementia status. DESIGN : Prospective historical study. SETTINGS community based. PARTICIPANTS from the 10,059 male Jewish civil servants who participated in the Israel Ischemic Heart Disease study in the 1960s, the 1,713 who were evaluated for dementia in 1999/2000 and who were unequivocally classified as demented or nondemented. MEASUREMENTS : Midlife sociodemographic and cardiovascular risk factors, late-life dementia, and mortality. RESULTS over a period of 6 years, 718 (42%) subjects died. Of the 307 demented subjects, 71.8% died and of the 1,407 nondemented subjects, 35.4% died. Multivariate survival analyses showed that compared with subjects without dementia, demented subjects had a hazard ratio [HR] for mortality of 2.27 (95% confidence interval [CI] 1.92-2.68). Other risk factors associated with mortality were socioeconomic status (HR 0.94 [0.88-1.00]), higher systolic (HR 1.16 per 20 mm Hg [1.06-1.28 mm Hg]) and diastolic blood pressure (HR 1.15 per 10 mm Hg [1.06-1.25 mm Hg]), and ever smoking (HR 1.38 [1.18-1.61]). Midlife total cholesterol was not associated with mortality (1.01 per 40 mg/dL [0.93-1.10 mg/dL]). None of the interactions of the risk factors with dementia was significant. CONCLUSIONS dementia was associated with more than double the risk of mortality, but this increased risk did not reflect exacerbation by midlife sociodemographic and cardiovascular risk factors. Our findings suggest that the dementing process itself or its consequences may go beyond well-established midlife risk factors for mortality.

Flavonoid intake and disability-adjusted life years due to Alzheimer’s and related dementias: a population-based study involving twenty-three developed countries. Public Health Nutr 2010; 13:1403-9.

Abstract
AbstractObjectiveDietary flavonoids and their metabolites may have neuroprotective effects against age-associated neurodegenerative disorders such as Alzheimer’s and related dementias (dementia). There is a lack of population studies, however, on correlations between flavonoid intake and dementia. The main objective of the present study was to analyse such a relationship at a large-scale population level.DesignBased on global data (FAO, WHO), databases were generated for: (i) flavonoid content of foods; (ii) per capita national dietary intakes of flavonoids and other dietary factors; and (iii) disability-adjusted life years – a measure of burden and death – due to dementia. Five major flavonoid subclasses were examined. To minimize influences due to accuracy and reliability of the disease source data, twenty-three developed countries were selected after statistical evaluation.ResultsFlavonols and combined flavonoids (all five combined) intakes were the only two parameters with significant (P < 0·05) negative dementia correlations. Multiple linear regression models confirmed this relationship, and excluded confounding from some other dietary and non-dietary factors. Similar analyses with non-dementia, neurological/psychiatric diseases did not yield significant correlations.ConclusionsAt a global level, and in the context of different genetic backgrounds, our results suggest that higher consumption of dietary flavonoids, especially flavonols, is associated with lower population rates of dementia in these countries.

Abstract
BACKGROUND Socioeconomic status (SES) has been identified as a possible risk factor for the development of dementia, with low SES shown to be associated with a higher prevalence of dementia, increased psychiatric comorbidity and worse baseline cognitive functioning. Few studies have actually looked at the impact of SES within a clinical population using multiple measures of SES and cognition. METHODS Data on 217 patients seen in an Inner City Memory Disorders Clinic were analyzed with respect to demographic status, clinical status and SES. Correlations were then examined looking at the relationship of SES to clinical variables and neurocognitive status. Regression analysis was undertaken to examine the relative contribution of individual sociodemographic factors to a diagnosis of dementia. RESULTS In general, there was wide variation in the sample examined with respect to most measures of SES. Approximately one third (36%) of the sample had a diagnosis of dementia, the mean age was 66.1 years and the mean Mini-mental State Examination score was relatively high (25.4). There was a strong association between age, individual annual income range, education, medical comorbidity and a diagnosis of dementia, with increased age and medical comorbidity being the strongest predictors. CONCLUSION Increased age, low education, high medical comorbidity and low annual income are all associated with a diagnosis of dementia in an inner city setting. Age and medical comorbidity appear to be more strongly associated with a diagnosis of dementia than SES in an inner city setting.

Abstract
There are persistent disparities in Alzheimer's disease by race and ethnicity that are not well understood. The emphasis given to seeking a genetic basis for racial differences might be a distraction from the more relevant issue of identifying preventable causes of Alzheimer's disease. The majority of Alzheimer's disease cases are diagnosed as the late onset type and are unlikely to be inherited. Late onset Alzheimer's disease cases, therefore, more likely represent variations in gene expression than gene frequency. Although conceptual and methodologic problems have limited our understanding of this relationship, race-based studies provide important opportunities to understand the environmental factors associated with gene expression. Improving our understanding of the factors associated with race and ethnicity might help to clarify the epidemiology and course of Alzheimer's disease.
