- Longevity risk means living longer than predicted. Attempts to understand longevity risk to date have concentrated on single diseases, usually coronary heart disease, and sought explanations in terms of risk factor change and medical innovation. In an opening paper, David Blane and colleagues point to evidence that suggests changes in positive health also should be considered; and that a life course approach can do so in a way that is socially and biologically plausible. Applying this approach to UK citizens currently aged 85 years suggests that life course research should give priority to trajectories across the whole life course and to the social and material contexts through which each cohort has passed. Testing these ideas will require inter-disciplinary and international comparative research. The opening paper is followed by commentaries from Hans-Werner Wahl, Mark Hayward, Aart Liefbroer and Gita Mishra. Finally Blane and colleagues respond to the points raised by the commentators.

- Background: Resilience is having good outcomes despite adversity and risk and could be described in terms of preserving the same level of the outcome or rebounding back to that level after an initial set back. Using the latter definition, resilience as “bouncing back”, this paper aims (1) to identify those members of a panel survey who demonstrated resilience, and (2) to identify the characteristics of the resilient individuals and the predictors of their resilience.Methods: The study subjects were the 3581 participants in the British Household Panel Survey, selected from waves 1–14, who satisfied three requirements: exposure to an adversity; availability of consecutive General Health Questionnaire (GHQ)-12 scores; aged 50 or more years. The primary outcome variable was resilience, operationalised as a GHQ-12 score that increased after exposure to adversity and returned to its pre-exposure level in the next (after 1 year) wave of the survey. The adversities were: functional limitation; bereavement or marital separation; poverty.Results: The prevalence of resilience, as defined, was 14.5%. After adjusting for regression to the mean, the GHQ-12 score of the resilient dropped by a mean of 3.6 points in the post-adversity period. Women predominated among the resilient, with this gender difference stronger among older women than younger women. The resilient were more likely to have high social support than the non-resilient, but otherwise were not different socioeconomically. High social support pre-adversity and during adversity increased the likelihood of resilience by 40–60% compared with those with low social support.Conclusions: Resilience is relatively rare and favours older women. It is fostered by high levels of social support existing before exposure to adversity.

Decreasing rate of fatty involution at screening mammography

Tidskriftsartikel (refereegranskat)abstract
- RATIONALE AND OBJECTIVES: This study was performed to document the perceived decrease in fatty involution at screening mammography during the past decade and evaluate the influence of hormone replacement therapy (HRT). MATERIALS AND METHODS: In December 1996, the mammograms of 261 consecutive screening patients with a comparison study obtained 5 years earlier were evaluated, and their breasts were categorized according to Breast Imaging Reporting and Data System categories for breast density. The women, aged 50-59 years, included 119 who had been receiving HRT for 0.25-15 years (mean, 3 years). From the files, 261 age-matched screening mammograms from 1986 were obtained; these patients also had comparison mammograms from 1981. Analysis of variance was used to determine differences between the 1980s group, the 1990s group receiving HRT, and the 1990s group not receiving HRT. Scheffe tests were used for post hoc comparisons. Stepwise regression analysis was used to evaluate the relative influence of age, decade, score of the first mammogram, and HRT. RESULTS: Breast density for the 1991 mammograms did not differ significantly from that in 1981 (P < .05). Initial breast density was the best predictor of final breast density in both decades (P < .001), regardless of HRT status. The change in breast density (toward fatty) over the 5-year interval in the 1980s (mean, 0.48) was significantly greater than that in both 1990s groups (mean for HRT group, 0.11; no HRT, 0.30; P < .05). CONCLUSION: These results confirm that breast density at screening mammography in the 1990s did not decrease with age at the same rate as in the 1980s, even in patients not receiving HRT.

- PURPOSE: This article examines resilience at older ages, focusing on the relationships between quality of life (qol) and adversity. Our objectives are to identify (a) the basis of adversity, (b) the characteristics of resilient individuals, and (c) the attributes that attenuate the full impact of adversity. DESIGN AND METHODS: Resilience is defined as flourishing despite adversity. Analysis is carried out in a subsample of the Boyd Orr cohort (aged between 68 and 82 years) using questionnaire data. Adversity was identified as circumstances that produce a significant average decrease in qol (CASP-19 scores). Participants were classified into resilient and vulnerable groups based on high or low qol (CASP-19 scores dichotomized at the median) in the face of significant adversity. Shared characteristics that define these outcomes are reported. Attributes that attenuate the negative impact of adversity were analyzed using stratified logistic regression. RESULTS: Adversity was typified by functional limitation; life getting worse in the domains of health, stress, and general living circumstances; and experiencing a negative life event. The resilient tended to report fewer multiple adversities. Indicators of protective attributes, which also characterized resilient outcomes relative to qol, included good quality relationships (5.105, confidence interval [CI] 95% 1.323-19.699), integration in the community (10.800, 95% CI 1.227-95.014), developmental coping (3.397, 95% CI 1.079-10.690), and adaptive coping styles (3.211, 95% CI 1.041-9.910). IMPLICATION: Overall results indicate that policies that offer access to protection and help minimize adversity exposure where possible will promote resilience.

Vaccine elicitation of HIV broadly neutralizing antibodies from engineered B cells

- HIV broadly neutralizing antibodies (bnAbs) can suppress viremia and protect against HIV infection. However, their elicitation is made difficult by low frequencies of appropriate precursor B cell receptors and the complex maturation pathways required to generate bnAbs from these precursors. Antibody genes can be engineered into B cells for expression as both a functional antigen receptor on cell surfaces and as secreted antibody. Here, we show that HIV bnAb-engineered primary mouse B cells can be adoptively transferred and vaccinated in immunocompetent mice resulting in the expansion of durable bnAb memory and long-lived plasma cells. Somatic hypermutation after immunization indicates that engineered cells have the capacity to respond to an evolving pathogen. These results encourage further exploration of engineered B cell vaccines as a strategy for durable elicitation of HIV bnAbs to protect against infection and as a contributor to a functional HIV cure.
