Cohort trends in intrinsic capacity in England and China.

To understand how the health of older adults today compares to that of previous generations, we estimated intrinsic capacity and subdomains of cognitive, locomotor, sensory, psychological and vitality capacities in participants of the English Longitudinal Study of Ageing and the China Health and Retirement Longitudinal Study. Applying multilevel growth curve models, we found that more recent cohorts entered older ages with higher levels of capacity, while subsequent age-related declines were somewhat compressed compared to earlier cohorts. Trends were most evident for the cognitive, locomotor and vitality capacities.

Tackling algorithmic bias and promoting transparency in health datasets: the STANDING Together consensus recommendations.

Without careful dissection of the ways in which biases can be encoded into artificial intelligence (AI) health technologies, there is a risk of perpetuating existing health inequalities at scale. One major source of bias is the data that underpins such technologies. The STANDING Together recommendations aim to encourage transparency regarding limitations of health datasets and proactive evaluation of their effect across population groups.

Effects of perfluorooctanoic acid and nano titanium dioxide on the immune response and energy allocation in Mytilus coruscus.

Perfluorooctanoic acid (PFOA) functions as a surfactant, while nano-titanium dioxide (nano-TiO) serves as an antibacterial agent. These substances are extensively utilized in industrial production and, upon release into aquatic environments, pose significant threats to the viability and development of marine organisms. However, research into the effects of PFOA and nano-TiO on the immune functions and cellular energy allocation (CEA) of bivalves remains limited.

The changing global landscape of national cancer control plans.

Improving implementation of needle and syringe programmes to expand, scale up, and sustain evidence-based prevention interventions for HIV and hepatitis C in prisons.

The 1990 resolution by the UN General Assembly committed member states to provide health-care equity for people in prison, who are included in the global goals to control HIV and eliminate hepatitis C virus (HCV) by 2030. WHO has set ambitious HCV elimination targets by including people who inject drugs (PWID), yet has not prioritised PWID who are incarcerated, a substantial population who have or are at risk for HCV infection. Human rights principles of health-care equity stipulate that "prisoners should enjoy the same standards of health care that are available in the community, without discrimination on the grounds of their legal status".

Engineering and structures of Crimean-Congo hemorrhagic fever virus glycoprotein complexes.

Crimean-Congo hemorrhagic fever virus (CCHFV) is a tickborne virus that can cause severe disease in humans with case fatality rates of 10%-40%. Although structures of CCHFV glycoproteins GP38 and Gc have provided insights into viral entry and defined epitopes of neutralizing and protective antibodies, the structure of glycoprotein Gn and its interactions with GP38 and Gc have remained elusive. Here, we use structure-guided protein engineering to produce a stabilized GP38-Gn-Gc heterotrimeric glycoprotein complex (GP38-Gn-Gc).

Cytochrome P450 phenotyping using the Geneva cocktail improves metabolic capacity prediction in a hospitalized patient population.

Aims: Liver cytochromes (CYPs) play an important role in drug metabolism but display a large interindividual variability resulting both from genetic and environmental factors. Most drug dose adjustment guidelines are based on genetics performed in healthy volunteers. However, hospitalized patients are not only more likely to be the target of new prescriptions and drug treatment modifications than healthy volunteers, but will also be more subject to polypharmacy, drug-drug interactions, or to suffer from disease or inflammation affecting CYP activities.

Exploring the performance of a DOI-capable TOF-PET module using different SiPMs, customized and commercial readout electronics.

Tipping detection using climate networks.

The development of robust Early Warning Signals (EWSs) is necessary to quantify the risk of crossing tipping points in the present-day climate change. Classically, EWSs are statistical measures based on time series of climate state variables, without exploiting their spatial distribution. However, spatial information is crucial to identify the starting location of a transition process and can be directly inferred by satellite observations.
