This is not your parents' retirement: comparing retirement income across generations

This article examines how retirement income at age 67 is likely to change for baby boomers and persons born in generation X (GenX) compared with current retirees. We use the Social Security Administration's Modeling Income in the Near Term (MINT) model to project retirement income and assets, poverty rates, and replacement rates for current and future retirees at age 67. We find that, in absolute terms, retirement incomes offuture cohorts will increase over time, and poverty rates will fall. However, projected income gains are larger for higher than for lower socioeconomic groups, leading to increased income inequality among future retirees. Finally, because postretirement incomes are not expected to rise as much as preretirement incomes, baby boomers and GenXers are less likely to have enough postretirement income to maintain their preretirement standard of living compared with current retirees.

Racial and ethnic differences in the retirement prospects of divorced women in the Baby Boom and Generation X cohorts

Blacks, Hispanics, and divorced women have historically experienced double-digit poverty rates in retirement, and divorce and other demographic trends will increase their representation in future retiree populations. For these reasons, we might expect an increase in the proportion of economically vulnerable divorced women in the future. This article uses the Social Security Administration's Modeling Income in the Near Term (version 6) to describe the likely characteristics, work experience, Social Security benefit status, and economic well-being of future divorced women at age 70 by race and ethnicity. Factors associated with higher retirement incomes include having a college degree; having a strong history of labor force attachment; receiving Social Security benefits; and having pensions, retirement accounts, or assets, regardless of race and ethnicity. However, because divorced black and Hispanic women are less likely than divorced white women to have these attributes, income sources, or assets, their projected average retirement incomes are lower than those of divorced white women.

The retirement prospects of divorced women

For decades, policymakers have discussed how to remedy the high poverty rates of older widows. Yet older divorced women are more likely to be poor than older widows, and historical divorce and remarriage trends suggest that in the future a larger share of retired women will be divorced. This article uses the Social Security Administration's Modeling Income in the Near Term (version 6) to project the retirement resources and wellbeing of divorced women. We find that Social Security benefits and retirement incomes are projected to increase for divorced women and that their poverty rates are projected to decline, due in large part to women's increasing lifetime earnings. However, not all divorced women will be equally well off economic well-being in retirement varies by Social Security benefit type.

Trends in the obstetric features and management of twin pregnancies

There are no reports outlining the trends in obstetric features and clinical management of twin pregnancies in an Irish obstetric population. The aim of this study was to investigate these factors for all twin pregnancies delivered during the 19 year period between 1989 and 2007, at Galway University Hospital (GUH). There were 52,199 infants delivered at GUH, of which 1594 infants (3.05% of births) were twins, related to 797 twin pregnancies. The overall incidence of twin pregnancies was 1.52%, increasing from 0.8%-1.0% in the early years of the study to 1.7-1.8% in the latter years of the study (P<0.001). There was a significant increase in incidence of twins born to mothers aged 30-39 years, alongside a significant reduction to mothers aged 20-29 years (P<0.01). The caesarean section rate overall was 41.5% (331/797), of which 54% (n=179) were elective, and 46% (n=152) were emergency, representing an emergency caesarean section rate of 19.1% of all twin pregnancies, and of 24.6% after exclusion of elective caesarean sections. The caesarean section rate for twins increased from 30% in 1989 to greater than 50% in the latter years of the study (P<0.01), related largely to a significant increase in elective caesarean sections (P<0.01). The combined vaginal-caesarean delivery rate was remarkably low at 0.75% of all twin pregnancies, and 1% after exclusion of elective caesarean sections. The preterm delivery rates were 4.1% (<32 weeks), and 16.3% (<36 weeks), with an overall perinatal mortality rate of 37 per 1000. These findings highlight the altered demographic and clinical aspects of twin pregnancies in an Irish obstetric population.

Patient perspectives of Condition Management Programmes as a route to better health, well-being and employability

BACKGROUND

Condition Management Programmes (CMPs), delivered through primary care settings, have been identified as possible vehicles to facilitate return to work for individuals with chronic health problems. There is little research, however, which examines how such programmes are received by patients.

OBJECTIVE

To explore patients' experiences of CMPs in terms of health, well-being and employability.

METHODS

Four focus groups and nine semi-structured interviews were conducted in order to capture patients' (n = 25) perceptions and experiences regarding participation in one of five different CMPs: Cardiac Rehabilitation, Counselling, Lower Back Pain Services, Smoking Cessation and a GP Exercise Referral Programme.

RESULTS

Experiences of the CMPs were generally positive. Respondents reported improved health behaviours (specifically better diets and increased exercise), positive psychosocial outcomes (including increased self-esteem, confidence and social support) and in some cases, return to work. However, concerns were expressed about the shortness of interventions and their accessibility.

CONCLUSIONS

Although condition management appears to have been well received by participants, the findings also illustrate that there is no 'one size fits all' template for CMPs. Rather, interventions should be adapted to take account of the dynamics of specific conditions, the context in which the intervention is based and the characteristics of the individuals involved.

Electronic excitations in the correlated metal BaV(0.98)Ti(0.02)S(3) studied using resonant inelastic soft x-ray scattering

Electronic excitations in the correlated metal BaTi(0.02)V(0.98)S(3) have been studied using resonant inelastic soft x-ray scattering at the V L edge. The intensities of the intra-atomic d-d(*) excitations and the elastic x-ray scattering feature are found to be temperature dependent, with the intensity increasing with decreasing temperature until saturation is reached near 100 K. The behavior of the spectral features is interpreted as evidence of a shift in the 3d electrons from more band-like states at higher temperature to more localized states at low temperature.

Executive dysfunction in poor readers born prematurely at high risk

This study examined the relation between a preterm birth and reading ability and whether children born preterm with poorer reading were more likely to show lower cognitive and executive functioning skills compared to children born at term with poor reading ability. Participants born at term (N = 97) and preterm (N = 156) were studied using the Woodcock-Johnson Test of Achievement Word Attack subtest (WJWA), Stanford-Binet Intelligence Scale, Comprehensive Evaluation of Language Fundamentals, and executive function tasks during the 3rd, 5th, and 7th grades. Children born prematurely were divided into low (N = 94) and high (N = 62) risk groups based on severity of neonatal complications. Growth in WJWA scores was used to cluster the sample into three reading ability groups. Contrary to predictions, children born preterm were not more likely to be in the poor reading group. Poorer reading ability was associated with lower language and cognitive scores. The effect of premature birth demonstrated fewer and weaker associations with such scores. A significant interaction between reading ability and birth status indicated that high risk prematurely born children with poor reading ability were more likely than the other groups to perform poorly on executive function tasks. These data suggest that better reading ability is associated with better neuropsychological function independent of prematurity.

Electronic structure of the organic semiconductor Alq3 (aluminum tris-8-hydroxyquinoline) from soft x-ray spectroscopies and density functional theory calculations

The element-specific electronic structure of the organic semiconductor aluminum tris-8-hydroxyquinoline (Alq(3)) has been studied using a combination of resonant x-ray emission spectroscopy, x-ray photoelectron spectroscopy, x-ray absorption spectroscopy, and density functional theory (DFT) calculations. Resonant and nonresonant x-ray emission spectroscopy were used to measure directly the carbon, nitrogen and oxygen 2p partial densities of states in Alq(3), and good agreement was found with the results of DFT calculations. Furthermore, resonant x-ray emission at the carbon K-edge is shown to be able to measure the partial density of states associated with individual C sites. Finally, comparison of previous x-ray emission studies and the present data reveal the presence of clear photon-induced damage in the former.

The disappearing defined benefit pension and its potential impact on the retirement incomes of baby boomers

This article uses a microsimulation model to estimate how freezing all remaining private-sector and one-third of all public-sector defined benefit (DB) pension plans over the next 5 years would affect retirement incomes of baby boomers. If frozen plans were supplemented with new or enhanced defined contribution (DC) retirement plans, there would be more losers than winners, and average family incomes would decline. The decline in family income would be much larger for last-wave boomers born from 1961 through 1965 than for those born from 1946 through 1950, because younger boomers are more likely to have their DB pensions frozen with relatively little job tenure. Higher DC accruals would raise retirement incomes for some families by more than their lost DB benefits. But about 26 percent of last-wave boomers would have lower family incomes at age 67, and only 11 percent would see their income increase.

A responsive parenting intervention: the optimal timing across early childhood for impacting maternal behaviors and child outcomes

This study examined the optimal timing (infancy, toddler-preschool, or both) for facilitating responsive parenting and the intervention effects on maternal behaviors and child social and communication skills for children who vary in biological risk. The intervention during infancy, Playing and Learning Strategies (PALS I), showed strong changes in maternal affective-emotional and cognitively responsive behaviors and infants' development. However, it was hypothesized that a 2nd intervention dose in the toddler-preschool period was needed for optimal results. Families from the PALS I phase were rerandomized into either the PALS II, the toddler-preschool phase, or a Developmental Assessment Sessions condition, resulting in 4 groups. Facilitation of maternal warmth occurred best with the PALS I intervention, while cognitive responsive behaviors were best supported with the PALS II intervention. Behaviors that required responsiveness to the child's changing signals (contingent responsiveness, redirecting) required the intervention across both the early and later periods.

Health inequalities in England, Scotland and Wales: stakeholders' accounts and policy compared

OBJECTIVES

The election of a Labour government in 1997 brought the issue of health inequalities firmly back on to the policy agenda across the UK. Since then, in the wake of devolution, the need to tackle health inequalities has been highlighted as a policy priority in all three mainland UK countries, albeit with varying degrees of emphasis. This paper reports on a major cross-national study, funded by the Economic and Social Research Council, investigating how National Health Service bodies, local councils and partnerships make sense of their work on health inequalities, and examining the difference made by the contrasting approaches that have been taken to performance assessment in England, Wales and Scotland.

STUDY DESIGN

Case studies, semi-structured interviews and analysis of key policy statements.

METHODS

In order to explore how health inequalities have been approached by the three governments (noting that there was a change in governments in Wales and Scotland during this time), key policy statements published between May 1997 and May 2007 were analysed. Concurrently, data from stakeholder interviews carried out in 2006 in case study areas in each country were analysed to determine the extent of alignment between policy and practice at local level.

RESULTS

This paper suggests that claims about the extent of health policy divergence in post-devolution Britain may have been exaggerated. It finds that, whilst the three countries have taken differing approaches to performance assessment and the setting of targets, policy approaches to health inequalities up until 2007 appear to have been remarkably similar. Furthermore, the first round of interview data suggest that variations in local understandings of, and responses to, health inequalities cannot always be clearly distinguished along national lines.

CONCLUSIONS

Based on the policy analysis, devolution in the UK does not appear to have resulted in substantively different national policy approaches to health inequalities. Indeed, the overall analysis suggests that (prior to the 2007 elections in Scotland and Wales) the differences between local areas within countries may be of as much interest as those between countries.

A multi-state Salmonella Typhimurium outbreak associated with frozen vacuum-packed rodents used to feed snakes

From December 2005 through January 2006, the Minnesota Department of Health (MDH) identified four human clinical isolates of Salmonella Typhimurium that were indistinguishable by pulsed-field gel electrophoresis (PFGE). During routine interviews, three of the cases reported attending the same junior high school and two handled snakes in the science classroom. MDH collected environmental samples from the school's science classroom for Salmonella culturing; these included environmental samples and frozen vacuum-packed mice purchased over the internet to feed the classroom snakes. Through PulseNet, a national molecular subtyping surveillance network for enteric bacteria, 21 human S. Typhimurium isolates with indistinguishable PFGE patterns were identified in the United States since December 2005. Each state determined whether these human cases had recent exposure to snakes fed vacuum-packed rodents. Texas state officials conducted tracebacks of the vacuum-packed mice and collected samples at the breeding facility. Nineteen of 21 cases were interviewed, and seven reported contact with frozen vacuum-packed rodents from the same internet-based supplier in Texas. In Minnesota, the outbreak PFGE subtype of S. Typhimurium was isolated from the snakes, frozen feed rodents, and the classroom environment. Three human cases were identified in Michigan, Pennsylvania, and Wyoming. The outbreak PFGE subtype of S. Typhimurium was isolated from the Pennsylvania case's frozen rodents and the Michigan case's pet snake. The outbreak PFGE subtype of S. Typhimurium was also isolated from the supplier's rodent facility. This was a S. Typhimurium outbreak associated with frozen rodents. Human transmission likely occurred through direct contact with snakes and contaminated environmental surfaces. This report represents the second recent multi-state salmonellosis outbreak associated with commercially distributed rodents. Stronger oversight of the commercial rodent industry is warranted.

The UCSC Genome Browser Database: update 2009

The UCSC Genome Browser Database (GBD, http://genome.ucsc.edu) is a publicly available collection of genome assembly sequence data and integrated annotations for a large number of organisms, including extensive comparative-genomic resources. In the past year, 13 new genome assemblies have been added, including two important primate species, orangutan and marmoset, bringing the total to 46 assemblies for 24 different vertebrates and 39 assemblies for 22 different invertebrate animals. The GBD datasets may be viewed graphically with the UCSC Genome Browser, which uses a coordinate-based display system allowing users to juxtapose a wide variety of data. These data include all mRNAs from GenBank mapped to all organisms, RefSeq alignments, gene predictions, regulatory elements, gene expression data, repeats, SNPs and other variation data, as well as pairwise and multiple-genome alignments. A variety of other bioinformatics tools are also provided, including BLAT, the Table Browser, the Gene Sorter, the Proteome Browser, VisiGene and Genome Graphs.

Urodynamic evaluation of the bladder and pelvic floor

Pelvic floor disorders including lower urinary tract dysfunction are common, and may be evaluated by urodynamic tests, such as cystometry, uroflowmetry, pressure flow studies, electromyography, and video-urodynamics. These urodynamic tests provide objective information regarding the normal and abnormal function of the urinary tract and pelvic floor, and provide a better understanding of the pathophysiologic processes that cause lower urinary tract symptoms. This article describes typical urodynamic studies and their roles in the evaluation of common pelvic floor disorders, including stress urinary incontinence, overactive bladder, and pelvic organ prolapse.

Dissipation of PAHs in saturated, dredged sediments: a field trial

Sediments dredged from navigable rivers often contain elevated concentrations of recalcitrant, potentially toxic organic compounds such as polychlorinated biphenyls (PCBs) and polyaromatic hydrocarbons (PAHs). The presence of these compounds often requires that the sediments be stored in fully contained disposal facilities. A 3-year field study was conducted at the Jones Island disposal facility in Milwaukee, Wisconsin, to compare bioremediation of PAHs in contaminated dredged sediments in the absence of plants to phytoremediation with Salix nigra (black willow) (SX61), Spartina pectinata (prairie cord grass), Carex aquatalis (lake sedge), Lolium multiflorum (annual rye), and Scirpus fluviatilis (bulrush). Nine PAHs were detected initially in the sediments. Over the 3-year experiment, acenaphthene dissipation ranged from 94% to 100%, whereas anthracene, benzo[a]pyrene and indo[1,2,3-cd]pyrene generally had modest decreases in concentration (0-30% decrease). The remaining five PAHs ranged in degree of disappearance from 23% to 82%. Planted treatments did not enhance PAH dissipation relative to those without plants, but treatments with high biomass yield and high transpiration plant species had significantly less removal of PAHs than unplanted controls. Significant, negative correlations between nitrogen removal and decreases in PAH concentration suggest that competition for nutrients between plants and microorganisms may have impeded the microbial degradation of PAHs in the rhizosphere of the more rapidly growing plant species.

The UCSC Genome Browser Database: 2008 update

The University of California, Santa Cruz, Genome Browser Database (GBD) provides integrated sequence and annotation data for a large collection of vertebrate and model organism genomes. Seventeen new assemblies have been added to the database in the past year, for a total coverage of 19 vertebrate and 21 invertebrate species as of September 2007. For each assembly, the GBD contains a collection of annotation data aligned to the genomic sequence. Highlights of this year's additions include a 28-species human-based vertebrate conservation annotation, an enhanced UCSC Genes set, and more human variation, MGC, and ENCODE data. The database is optimized for fast interactive performance with a set of web-based tools that may be used to view, manipulate, filter and download the annotation data. New toolset features include the Genome Graphs tool for displaying genome-wide data sets, session saving and sharing, better custom track management, expanded Genome Browser configuration options and a Genome Browser wiki site. The downloadable GBD data, the companion Genome Browser toolset and links to documentation and related information can be found at: http://genome.ucsc.edu/.

The association of early blood oxygenation with child development in preterm infants with acute respiratory disorders

The potential negative impact of early blood oxygenation on development of specific cognitive and motor outcomes in children born at very low birth weight (VLBW; 1000-1500g) has not been examined even though these infants are exposed to varying durations and amounts of oxygen as part of their neonatal care. While this is the largest group of preterm infants, they receive much less research attention than extremely low birth weight infants (ELBW<1000g). Although neonatologists are questioning the routine use of oxygen therapy for all neonates, research has focused primarily on the more medically fragile ELBW infants. To date there are no systematic studies available to guide decision making for oxygen supplementation for a large segment of the preterm infant population. The aim of the present study was to determine if there is an association between blood oxygenation in the first 4h of life and specific cognitive and motor skills in preterm infants with acute respiratory disorders but no severe intracranial insult using a selected cohort from a longitudinal study children recruited in 1991 and 1992 designed to examine the role of biological immaturity as defined by gestational age and parenting in development. From this cohort, 55 children had acute respiratory disorders without severe intracranial insult. Of these, 35 children had at least one partial pressure of oxygen obtained from arterial blood (PaO2) during the first 4h of life as part of their clinical care. Higher early PaO2 values were associated with lower impulse control and attention skills in the elementary school age period. Models that were examined for relations between PaO2 values that also included birth weight and parenting quality across the first year of life revealed that higher PaO2 remained associated with impulse control but not attention skills. Birth weight was not associated with any outcomes. These results suggest that hyperoxia may be a risk factor for developmental problems that are not expressed until school age.

Inhibition of inducible nitric oxide synthase enhances anti-tumour immune responses in rats immunized with IFN-gamma-secreting glioma cells

Interferon gamma (IFN-gamma) has successfully been used in immunotherapy of different experimental tumours. Mechanistically, IFN-gamma has extensive effects on the immune system including release of nitric oxide (NO) by upregulation of the inducible nitric oxide synthase (iNOS). NO has putative immunosuppressive effects but could also play a role in killing of tumour cells. Therefore, the aim of the present study was to clarify whether inhibition of iNOS in rats immunized with glioma cells (N32) producing IFN-gamma (N32-IFN-gamma), could enhance the anti-tumour immune response. Initially, both a selective iNOS, l-N(6)-(1-Iminoethyl)-l-lysine (l-NIL), and non-selective, N-nitro-l-arginine methyl ester (l-NAME), inhibitor of NOS were tested in vitro. After polyclonal stimulation with LPS and SEA, both l-NIL and l-NAME enhanced proliferation and production of IFN-gamma from activated rat splenocytes and this effect was inversely correlated to the production of NO. However, l-NIL had a broader window of efficacy and a lower minimal effective dose. When rats were immunized with N32-IFN-gamma, and administered NOS inhibitors by intraperitoneal (i.p.) mini-osmotic pumps, only splenocytes of rats treated with l-NIL, but not l-NAME, displayed an enhanced proliferation and production of IFN-gamma when re-stimulated with N32 tumour cells. Based on these findings, l-NIL was administered concurrently with N32-IFN-gamma cells to rats with intracerebral (i.c.) tumours resulting in a prolonged survival. These results show that inhibition of iNOS can enhance an IFN-gamma-based immunotherapy of experimental i.c. tumours implying that NO released after immunization has mainly immunosuppressive net effects.
