Neighborhood Social Resources and Depressive Symptoms: Longitudinal Results from the Multi-Ethnic Study of Atherosclerosis
The ways in which a neighborhood environment may affect depression and depressive symptoms have not been thoroughly explored. This study used longitudinal data from 5475 adults in the Multi-Ethnic Study of Atherosclerosis to investigate associations of time-varying depressive symptoms between 2000 and 2012 (measured using the 20-item Center for Epidemiologic Studies Depression Scale (CES-D)) with survey-based measures of neighborhood safety and social cohesion (both individual-level perceptions and neighborhood-level aggregates) and densities of social engagement destinations. Linear mixed models were used to examine associations of baseline cross-sectional associations and cumulative exposures with changes over time in CES-D. Econometric fixed effects models were utilized to investigate associations of within-person changes in neighborhood exposures with within-person changes in CES-D. Adjusting for relevant covariates, higher safety and social cohesion and greater density of social engagement destinations were associated with lower CES-D at baseline. Greater cumulative exposure to these features was not associated with progression of CES-D over 10 years. Within-person increases in safety and in social cohesion were associated with decreases in CES-D, although associations with cohesion were not statistically significant. Social elements of neighborhoods should be considered by community planners and public health practitioners to achieve optimal mental health
Incidence of new HIV diagnoses in Spain, 2004-2009.
[ES]
Objetivo
Describir la incidencia de nuevos diagnósticos de infección por el virus de la inmunodeficiencia humana (VIH) y su tendencia.
Métodos
Se incluyeron los nuevos diagnósticos de VIH notificados en 2009 en las 15 comunidades autónomas con sistemas de información (64% de la población española). Para analizar las tendencias durante 2004-2009 se incluyeron las nueve comunidades con datos en ese periodo. Se obtuvo información clínico-epidemiológica de las hojas de notificación de casos y se realizaron distribuciones de nuevos diagnósticos y diagnóstico tardío según distintas variables. Para evaluar las tendencias se ajustó un modelo de Poisson.
Resultados
En 2009 se notificaron 2.264 nuevos diagnósticos de VIH, la mayoría en hombres (80%). La mediana de edad al diagnóstico fue de 36 años (rango intercuartílico 29-43) y el 37,6% de los casos eran inmigrantes, destacando los latinoamericanos y los subsaharianos. La categoría de transmisión más común (42,5%) fue la de hombres que tienen sexo con hombres, seguida de la heterosexual (34,5%) y la parenteral (8,1%). Al diagnóstico, la mediana de CD4/μl era de 347 (rango intercuartílico: 152-555) y un 50,2% tenían <350. La tasa media de incidencia de nuevos diagnósticos entre 2004 y 2009 fue de 91,14 por millón de habitantes; se observó una tendencia creciente de las tasas entre los hombres que tienen sexo con hombres, y decreciente de la transmisión parenteral.
Conclusiones
La epidemiología del VIH en España ha cambiado mucho respecto a los años 1990. Actualmente predomina la transmisión sexual, sobre todo entre los hombres que tienen sexo con hombres, y los inmigrantes son parte importante de la epidemia. En 2004-2009, la tendencia es heterogénea en las tres categorías de transmisión más relevantes.

To describe the incidence of new HIV diagnoses and its trend in Spain.
All new HIV diagnoses notified to the case-registries of 15 autonomous regions (64% of the total Spanish population) in 2009 were analyzed. To evaluate trends from 2004 to 2009, data from only nine regions were available. Clinical-epidemiological data were obtained from the notification forms. Distributions of new HIV diagnoses and late diagnoses according to several variables were performed. The Poisson distribution was used to evaluate trends.
In 2009, 2264 new HIV diagnoses were notified, mostly in men (80%). The median age at diagnosis was 36 years (interquartile range 29-43) and 37.6% of affected individuals were immigrants, mostly from Latin-America and sub-Saharan Africa. The most common transmission category (42.5%) was men who have sex with men (MSM) followed by the heterosexual and parenteral modes of transmission (34.5% and 8.1%, respectively). The median CD4 count at diagnosis was 347 (interquartile range: 152-555), and CD4 count was <350 in 50.2% of patients. From 2004 to 2009, the mean incidence rate of new HIV diagnoses was 91.14 per million inhabitants; an increasing trend for rates in MSM, as well as a decreasing trend for the parenteral mode of transmission, were observed.
In Spain, the epidemiology of HIV infection has changed since the mid-1990s. Currently, the most frequent transmission category is sexual transmission, particularly among MSM, and immigrants are an important part of the epidemic. Heterogeneous trends for the three main transmission categories were observed from 2004 to 2009.S
Association of salivary cortisol circadian pattern with cynical hostility: multi-ethnic study of atherosclerosis
OBJECTIVE: To determine if cynical hostility is associated with alterations in diurnal profiles of cortisol. Hostility has been linked to cardiovascular disease but the biological mechanisms mediating this association remain unknown.
METHODS: Up to 18 measures of salivary cortisol taken over 3 days were obtained from each of 936 participants in the Multi-Ethnic Study of Atherosclerosis (MESA). Cynical hostility was measured using an eight-item subscale of the Cook-Medley Hostility Scale. Cortisol profiles were modeled using regression spline models that incorporated random parameters for subject-specific effects. Models were adjusted for race, sex, age, socioeconomic position, and lifestyle factors. The association of cynical hostility with key features of the cortisol diurnal profile, both in the full sample and important subsamples, was examined.
RESULTS: Waking cortisol levels as well as the extent of the morning surge in cortisol levels did not differ significantly across tertiles of cynical hostility. Respondents in the lowest tertile of cynical hostility experienced a 22% sharper decline in salivary cortisol (age- and sex-adjusted slope of -0.49 microg/dL per hour) than respondents in the highest tertile (-0.40 microg/dL per hour, p for difference = .0004). Intertertile differences in these parameters remained unaltered after further adjustment for potential confounders. This pattern of differences in cortisol diurnal profile tended to be related in a dose-response way to level of cynical hostility, and persisted in stratified analyses. Conclusions: Cynical hostility is associated with the declining phase of the awakening cortisol response. The implications of this for cardiovascular and other health outcomes remain to be determined.http://deepblue.lib.umich.edu/bitstream/2027.42/78520/1/RanjitDiezRoux2009_PsychosomMed.pd
Association of the MYH9 gene polymorphisms with chronic renal disease secondary to hypertensive nephrosclerosis, in a Caucasian population
Background: Hypertensive nephrosclerosis (HN) is a chronic kidney disease (CKD) associated to essential hypertension, but their causal relationship is controversial. New evidence suggests that MYH9 gene alterations are associated with HN in African Americans. The aim of this study is to investigate the role of this gene in Spanish Caucasians. Methods: We compare high-risk MYH9 variants of patients with HN recruited according to standard clinical criteria (CKD stages 3-5), with essential hypertensives without renal disease (estimated glomerular filtration rate (eGFR) > 60 ml/min/1,73m2 and albuminuria < 300 mg/g creatinine), and also CKD patients with HN and progressive impairment of renal function with those who were stable. Diabetics were excluded. Results: A blood sample was obtained for genetic study of 238 patients with HN-CKD and 233 hypertensive controls. The rs3752462-T and rs4821480-T (risk alleles for CKD) were more frequent in the CKD group, but without significant difference. We found no differences for these SPNs with blood pressure, creatinine, albuminuria or renal disease progression. Conclusions: The effect of two common MYH9 single nucleotide polymorphisms (SPNs) on the development of CKD secondary to HN in our Spanish Caucasian population is low or zero; in any case less than that found in other, mainly African Americans.Funding: This work was supported by grant Red de Investigación Renal-REDINREN from the Instituto Carlos III, and with funds from the Fundación Renal Iñigo Álvarez de Toledo (Iñigo Álvarez de Toledo Kidney Foundation) in the Molecular Genetics Grou
Relation between Neighborhood Environments and Obesity in the MESA
This study investigated associations between neighborhood physical and social environments and body mass index in 2,865 participants of the Multi-Ethnic Study of Atherosclerosis (MESA) aged 45–84 years and residing in Maryland, New York, and North Carolina. Neighborhood (census tract) environments were measured in non-MESA participants residing in MESA neighborhoods (2000–2002). The neighborhood physical environment score combined measures of a better walking environment and greater availability of healthy foods. The neighborhood social environment score combined measures of greater aesthetic quality, safety, and social cohesion and less violent crime. Marginal maximum likelihood was used to estimate associations between neighborhood environments and body mass index (kg/m2) before and after adjustment for individual-level covariates. MESA residents of neighborhoods with better physical environments had lower body mass index (mean difference per standard deviation higher neighborhood measure = –2.38 (95% confidence interval (CI): –3.38, –1.38) kg/m2 for women and –1.20 (95% CI: –1.84, –0.57) kg/m2 for men), independent of age, race/ethnicity, education, and income. Attenuation of these associations after adjustment for diet and physical activity suggests a mediating role of these behaviors. In men, the mean body mass index was higher in areas with better social environments (mean difference = 0.52 (95% CI: 0.07, 0.97) kg/m2). Improvement in the neighborhood physical environment should be considered for its contribution to reducing obesity.http://deepblue.lib.umich.edu/bitstream/2027.42/60334/1/Relation between Neighborhood Environments and Obesity in the Multiethnic Study of Atherosclerosis.pd
Socioeconomic and race/ethnic differences in daily salivary cortisol profiles: the multi-ethnic study of atherosclerosis.
It has often been hypothesized that stress and its biological consequences mediate the relationship between low socioeconomic status (SES) or minority status and poor cardiovascular disease outcomes. The objective of this study was to determine if daily cortisol patterns, a biomarker of the stress response, differ by race/ethnicity and socioeconomic status. Data were collected from 935 Black, White and Hispanic adults age 48-90 years old. Salivary cortisol samples were collected six times per day over 3 days: at awakening, 30min later, at 1000h, noon, 1800h and at bedtime. Blacks and Hispanics had lower levels of wake-up cortisol and less steep early declines, while Blacks had flatter and Hispanics steeper late day declines relative to Whites. Similarly the low socioeconomic status group also had lower levels of wake-up cortisol and less steep decline during the early part of the day. These patterns remained after adjustment for health behaviors and psychosocial factors. This study finds an association between salivary cortisol and race/ethnicity and SES in a multi-ethnic study population. Further work is needed to determine the health consequences of these differences.http://deepblue.lib.umich.edu/bitstream/2027.42/78335/1/HajatDiezRoux2010_Psychoneuroendo..pd
Acute Kidney Injury is Aggravated in Aged Mice by the Exacerbation of Proinflammatory Processes
Acute kidney injury (AKI) is more frequent in elderly patients. Mechanisms contributing to AKI (tubular cell death, inflammatory cell infiltration, impaired mitochondrial function, and prolonged cell-cycle arrest) have been linked to cellular senescence, a process implicated in regeneration failure and progression to fibrosis. However, the molecular and pathological basis of the age-related increase in AKI incidence is not completely understood. To explore these mechanisms, experimental AKI was induced by folic acid (FA) administration in young (3-months-old) and old (1-year-old) mice, and kidneys were evaluated in the early phase of AKI, at 48 h. Tubular damage score, KIM-1 expression, the recruitment of infiltrating immune cells (mainly neutrophils and macrophages) and proinflammatory gene expression were higher in AKI kidneys of old than of young mice. Tubular cell death in FA-AKI involves several pathways, such as regulated necrosis and apoptosis. Ferroptosis and necroptosis cell-death pathways were upregulated in old AKI kidneys. In contrast, caspase-3 activation was only found in young but not in old mice. Moreover, the antiapoptotic factor BCL-xL was significantly overexpressed in old, injured kidneys, suggesting an age-related apoptosis suppression. AKI kidneys displayed evidence of cellular senescence, such as increased levels of cyclin dependent kinase inhibitors p16ink4a and p21cip1, and of the DNA damage response marker γH2AX. Furthermore, p21cip1 mRNA expression and nuclear staining for p21cip1 and γH2AX were higher in old than in young FA-AKI mice, as well as the expression of senescence-associated secretory phenotype (SASP) components (Il-6, Tgfb1, Ctgf, and Serpine1). Interestingly, some infiltrating immune cells were p21 or γH2AX positive, suggesting that molecular senescence in the immune cells (“immunosenescence”) are involved in the increased severity of AKI in old mice. In contrast, expression of renal protective factors was dramatically downregulated in old AKI mice, including the antiaging factor Klotho and the mitochondrial biogenesis driver PGC-1α. In conclusion, aging resulted in more severe AKI after the exposure to toxic compounds. This increased toxicity may be related to magnification of proinflammatory-related pathways in older mice, including a switch to a proinflammatory cell death (necroptosis) instead of apoptosis, and overactivation of cellular senescence of resident renal cells and infiltrating inflammatory cells
