- It is well documented that some brain regions, such as association cortices, caudate, and hippocampus, are particularly prone to age-related atrophy, but it has been hypothesized that there are individual differences in atrophy profiles. Here, we document heterogeneity in regional-atrophy patterns using latent-profile analysis of 1,482 longitudinal magnetic resonance imaging observations. The results supported a 2-group solution reflecting differences in atrophy rates in cortical regions and hippocampus along with comparable caudate atrophy. The higher-atrophy group had the most marked atrophy in hippocampus and also lower episodic memory, and their normal caudate atrophy rate was accompanied by larger baseline volumes. Our findings support and refine models of heterogeneity in brain aging and suggest distinct mechanisms of atrophy in striatal versus hippocampal-cortical systems.

- We examined whether sleep quality and quantity are associated with cortical and memory changes in cognitively healthy participants across the adult lifespan. Associations between self-reported sleep parameters (Pittsburgh Sleep Quality Index, PSQI) and longitudinal cortical change were tested using five samples from the Lifebrain consortium (n = 2205, 4363 MRIs, 18-92 years). In additional analyses, we tested coherence with cell-specific gene expression maps from the Allen Human Brain Atlas, and relations to changes in memory performance. "PSQI # 1 Subjective sleep quality" and "PSQI #5 Sleep disturbances" were related to thinning of the right lateral temporal cortex, with lower quality and more disturbances being associated with faster thinning. The association with "PSQI #5 Sleep disturbances" emerged after 60 years, especially in regions with high expression of genes related to oligodendrocytes and S1 pyramidal neurons. None of the sleep scales were related to a longitudinal change in episodic memory function, suggesting that sleep-related cortical changes were independent of cognitive decline. The relationship to cortical brain change suggests that self-reported sleep parameters are relevant in lifespan studies, but small effect sizes indicate that self-reported sleep is not a good biomarker of general cortical degeneration in healthy older adults.

- Conventional randomized controlled trials (RCTs) can be expensive, time intensive, and complex to conduct. Trial recruitment, participation, and data collection can burden participants and research personnel. In the past two decades, there have been rapid technological advances and an exponential growth in digitized healthcare data. Embedding RCTs, including cardiovascular outcome trials, into electronic health record systems or registries may streamline screening, consent, randomization, follow-up visits, and outcome adjudication. Moreover, wearable sensors (i.e. health and fitness trackers) provide an opportunity to collect data on cardiovascular health and risk factors in unprecedented detail and scale, while growing internet connectivity supports the collection of patient-reported outcomes. There is a pressing need to develop robust mechanisms that facilitate data capture from diverse databases and guidance to standardize data definitions. Importantly, the data collection infrastructure should be reusable to support multiple cardiovascular RCTs over time. Systems, processes, and policies will need to have sufficient flexibility to allow interoperability between different sources of data acquisition. Clinical research guidelines, ethics oversight, and regulatory requirements also need to evolve. This review highlights recent progress towards the use of routinely generated data to conduct RCTs and discusses potential solutions for ongoing barriers. There is a particular focus on methods to utilize routinely generated data for trials while complying with regional data protection laws. The discussion is supported with examples of cardiovascular outcome trials that have successfully leveraged the electronic health record, web-enabled devices or administrative databases to conduct randomized trials.

Asymmetric thinning of the cerebral cortex across the adult lifespan is accelerated in Alzheimer’s disease

Tidskriftsartikel (refereegranskat)abstract
- Aging and Alzheimer’s disease (AD) are associated with progressive brain disorganization. Although structural asymmetry is an organizing feature of the cerebral cortex it is unknown whether continuous age- and AD-related cortical degradation alters cortical asymmetry. Here, in multiple longitudinal adult lifespan cohorts we show that higher-order cortical regions exhibiting pronounced asymmetry at age ~20 also show progressive asymmetry-loss across the adult lifespan. Hence, accelerated thinning of the (previously) thicker homotopic hemisphere is a feature of aging. This organizational principle showed high consistency across cohorts in the Lifebrain consortium, and both the topological patterns and temporal dynamics of asymmetry-loss were markedly similar across replicating samples. Asymmetry-change was further accelerated in AD. Results suggest a system-wide dedifferentiation of the adaptive asymmetric organization of heteromodal cortex in aging and AD.

- Nature-based solutions (NbS) to climate change currently have considerable political traction. However, national intentions to deploy NbS have yet to be fully translated into evidence-based targets and action on the ground. To enable NbS policy and practice to be better informed by science, we produced the first global systematic map of evidence on the effectiveness of nature-based interventions for addressing the impacts of climate change and hydrometeorological hazards on people. Most of the interventions in natural or semi-natural ecosystems were reported to have ameliorated adverse climate impacts. Conversely, interventions involving created ecosystems (e.g., afforestation) were associated with trade-offs; such studies primarily reported reduced soil erosion or increased vegetation cover but lower water availability, although this evidence was geographically restricted. Overall, studies reported more synergies than trade-offs between reduced climate impacts and broader ecological, social, and climate change mitigation outcomes. In addition, nature-based interventions were most often shown to be as effective or more so than alternative interventions for addressing climate impacts. However, there were substantial gaps in the evidence base. Notably, there were few studies of the cost-effectiveness of interventions compared to alternatives and few integrated assessments considering broader social and ecological outcomes. There was also a bias in evidence toward the Global North, despite communities in the Global South being generally more vulnerable to climate impacts. To build resilience to climate change worldwide, it is imperative that we protect and harness the benefits that nature can provide, which can only be done effectively if informed by a strengthened evidence base.

- BACKGROUND The long-term prognostic impact of post-discharge bleeding in the unique population of patients with acute coronary syndrome (ACS) treated without percutaneous coronary intervention (PCI) remains unexplored.OBJECTIVES The aim of this study was to assess the association between post-discharge bleeding and subsequent mortality after ACS according to index strategy (PCI or no PCI) and to contrast with the association between post-discharge myocardial infarction (MI) and subsequent mortality.METHODS In a harmonized dataset of 4 multicenter randomized trials (APPRAISE-2 [Apixaban for Prevention of Acute Ischemic Events-2], PLATO [Study of Platelet Inhibition and Patient Outcomes], TRACER [Thrombin Receptor Antagonist for Clinical Event Reduction in Acute Coronary Syndrome], and TRILOGY ACS [Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage Acute Coronary Syndromes]), the association between post-discharge noncoronary artery bypass graft-related GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) moderate, severe, or life-threatening bleeding (landmark 7 days post-ACS) and subsequent all-cause mortality was evaluated in a time-updated Cox proportional hazards analysis. Interaction with index treatment strategy was assessed. Results were contrasted with risk for mortality following post-discharge MI.RESULTS Among 45,011 participants, 1,133 experienced post-discharge bleeding events (2.6 per 100 patient-years), and 2,149 died during follow-up. The risk for mortality was significantly higher <30 days (adjusted hazard ratio: 15.7; 95% confidence interval: 12.3 to 20.0) and 30 days to 12 months (adjusted hazard ratio: 2.7; 95% confidence interval: 2.1 to 3.4) after bleeding, and this association was consistent in participants treated with or without PCI for their index ACS (p for interaction = 0.240). The time-related association between post-discharge bleeding and mortality was similar to the association between MI and subsequent mortality in participants treated with and without PCI (p for interaction = 0.696).CONCLUSIONS Post-discharge bleeding after ACS is associated with a similar increase in subsequent all-cause mortality in participants treated with or without PCI and has an equivalent prognostic impact as post-discharge MI.
