Abstract In a time of heightened social inequality and concern to reckon with its sources and consequences, the relevance of cumulative dis/advantage (CDA) to understanding patterns of aging has become even clearer, and CDA research has continued to expand in several fresh directions. Papers in this symposium will review the current state of knowledge regarding CDA and will present new analyses addressing key questions of its intersections with social change and its structural patterning. We will begin with a review of knowledge on comparative evidence regarding cumulative dis/advantage and its cross-national patterning. With regard to change, will examine the compare the effect of the 2008 recession and subsequent recovery across generational cohorts through a comparative examination of trajectories of income inequality. We will also present evidence on the impact of gender, focusing on women’s late-life health.

Abstract This study compares the effect of the 2008 recession and subsequent recovery across generational cohorts by evaluating age-cohort trajectories of income inequality. Using data from the 2007 to 2016 waves of the Survey of Consumer Finances, we examine the trajectory of inequality for the overall population and by cohort in years spanning the Great Recession and subsequent recovery. We find that increases in per-capita income and wealth observed at the population-level during the recovery were not reflected among households below the median, leading to increasing inequality. Within cohorts, we observe growing inequality within cohorts in their primary working years. Findings are consistent with a model of integrative cumulative dis/ advantage, which predicts increasing within-cohort inequality over the life course influenced both by persistent micro- and macro-level processes of increasing heterogeneity. Our analyses highlight the potential role of extreme business cycle fluctuations, booms and busts, to exacerbate this underlying process.

AbstractWe investigated whether interindividual attentional vulnerability moderates performance on domain-specific cognitive tasks during sleep restriction (SR) and subsequent recovery sleep. Fifteen healthy men (M ± SD, 22.3 ± 2.8 years) were exposed to three nights of baseline, five nights of 5-h time in bed SR, and two nights of recovery sleep. Participants completed tasks assessing working memory, visuospatial processing, and processing speed approximately every two hours during wake. Analyses examined performance across SR and recovery (linear predictor day or quadratic predictor day2) moderated by attentional vulnerability per participant (difference between mean psychomotor vigilance task lapses after the fifth SR night versus the last baseline night). For significant interactions between day/day2 and vulnerability, we investigated the effect of day/day2 at 1 SD below (less vulnerable level) and above (more vulnerable level) the mean of attentional vulnerability (N = 15 in all analyses). Working memory accuracy and speed on the Fractal 2-Back and visuospatial processing speed and efficiency on the Line Orientation Task improved across the entire study at the less vulnerable level (mean − 1SD) but not the more vulnerable level (mean + 1SD). Therefore, vulnerability to attentional lapses after SR is a marker of susceptibility to working memory and visuospatial processing impairment during SR and subsequent recovery.

Pepper (Capsicum annuum L.) is one of the most economically important crops worldwide. Heat stress (HS) can significantly reduce pepper yield and quality. However, changes at a molecular level in response to HS and the subsequent recovery are poorly understood. In this study, 17-03 and H1023 were identified as heat-tolerant and heat-sensitive varieties, respectively. Their leaves’ transcript abundance was quantified using RNA sequencing to elucidate the effect of HS and subsequent recovery on gene expression. A total of 11,633 differentially expressed genes (DEGs) were identified, and the differential expression of 14 randomly selected DEGs was validated using reverse-transcription polymerase chain reaction. Functional enrichment analysis revealed that the most enriched pathways were metabolic processes under stress and photosynthesis and light harvesting during HS and after recovery from HS. The most significantly enriched pathways of 17-03 and H1023 were the same under HS, but differed during recovery. Furthermore, we identified 38 heat shock factors (Hsps), 17 HS transcription factors (Hsfs) and 38 NAC (NAM, ATAF1/2, and CUC2), and 35 WRKY proteins that were responsive to HS or recovery. These findings facilitate a better understanding of the molecular mechanisms underlying HS and recovery in different pepper genotypes.

Abstract Background Sleep is critical for maintaining homeostasis in bodily and neurobehavioral functions. This homeostasis can be disturbed by sleep interruption and restored to normal by subsequent recovery sleep. Most research regarding recovery sleep (RS) effects has been conducted in specialized sleep laboratories, whereas small, less-well equipped research units may lack the possibilities to run studies in this area. Hence, the aims of the present study were to develop and validate an experimental protocol, which allows a thorough assessment of at-home recovery sleep after sleep deprivation. Methods The experimental protocol, comprising one night of baseline sleep (BL) at home, one night of monitored total sleep deprivation and a subsequent recovery night at home, was tested in a sample of 30 healthy participants. Subjects’ fatigue and alertness were assessed prior to and after each night. Sleep at home (BL, RS) was objectively assessed using portable polysomnography. To check whether our at-home sleep assessments yielded results that are comparable to those conducted in sleep laboratories, we compared the sleep data assessed in our study with sleep data assessed in laboratory studies. Results Sleep parameters assessed during RS exhibited changes as expected (prolonged total sleep time, better sleep efficiency, slow wave sleep rebound). Sleep parameters of BL and RS were in line with parameters assessed in previous studies examining sleep in a laboratory setting. Fatigue normalized after one night of RS; alertness partly recovered. Conclusions Our results suggest a successful implementation of our new experimental protocol, emphasizing it as a useful tool for future studies on RS outside of well-equipped sleep laboratories.

Abstract This research explores the possibility of creating an underground water reservoir by injecting treated wastewater and evaluates the recovery efficiency and water quality under different injection/recovery scenarios. An injection/recovery well was established in the Dammam Formation aquifer in Kuwait. Six observation wells were also drilled nearby to monitor the water levels and quality. A three-dimensional (3D) numerical hydraulic and transport model was set up using the coupled version of MODFLOW and MT3DMS. Four scenarios of cyclic and continuous injection with different injection and pumping rates stretching over 5,400 days were investigated. Two dispersivity values, low (10 m) and high (200 m), were used in each scenario in order to establish the minimum and maximum recovery limits of useful water that can be expected from the site. The combination of injection rate of 650 m3/d and subsequent recovery at 1,000 m3/d proved to be the optimum option for the storage of water, resulting in good recovery efficiency and acceptable water quality. Based on these results, it was concluded that aquifer storage is a feasible strategy for mitigating growing water scarcity in the State of Kuwait and other countries in the larger Middle East.

Takotsubo syndrome, or stress cardiomyopathy, is a relatively rare transient and reversible cardiomyopathy, although its diagnosis has increased in recent years, it presents as an acute coronary syndrome (ACS) or acute heart failure, its incidence is unknown exactly in Latin America and in Cuba. We present 2 cases seen in our hospital, both 63 and 55-year-old women with typical precordial pressure pain, the first triggering psychological stress and the second physical, with electrocardiographic changes consistent with anterior infarction and cardiogenic shock, which were found in the coronary angiographic study observed normal coronary arteries and ventriculography determined apical ballooning of the left ventricle characteristic of the syndrome, with subsequent recovery and favorable clinical evolution at 6 months.
