Comparative lifespan and healthspan of nonhuman primate species common to biomedical research

Abstract

There is a critical need to generate age- and sex-specific survival curves to characterize chronological aging consistently across nonhuman primates (NHP) used in biomedical research. Sex-specific Kaplan-Meier survival curves were computed in 12 translational aging models: baboon, bonnet macaque, chimpanzee, common marmoset, coppery titi monkey, cotton-top tamarin, cynomolgus macaque, Japanese macaque, pigtail macaque, rhesus macaque, squirrel monkey, and vervet/African green. After employing strict inclusion criteria, primary results are based on 12,269 NHP that survived to adulthood and died of natural/health-related causes. A secondary analysis was completed for 32,616 NHP that died of any cause. Results show a pattern of reduced male survival among catarrhines (African and Asian primates), especially macaques, but not platyrrhines (Central and South American primates). For many species, median lifespans were lower than previously reported. An important consideration is that these analyses may offer a better reflection of healthspan than lifespan since research NHP are typically euthanized for humane welfare reasons before their natural end of life. This resource represents the most comprehensive characterization of sex-specific lifespan and age-at-death distributions for 12 biomedically relevant species, to date. These results clarify relationships among NHP ages and provide a valuable resource for the aging research community, improving human-NHP age equivalencies, informing investigators of expected survival rates, providing a metric for comparisons in future studies, and contributing to understanding of factors driving lifespan differences within and among species.

Thoracoabdominal pressure transmission during prone and supine cardiopulmonary resuscitation in fresh-frozen human cadavers

Background: Prone cardiopulmonary resuscitation (CPR) may be necessary when turning a prone patient supine would delay chest compressions. Although prone compressions can generate arterial pressures comparable with or greater than supine CPR, the pathway of pressure transmission is uncertain. We examined synchronized intrathoracic, intra-abdominal, and central arterial pressures in both supine and prone positions. Methods: Two thawed fresh-frozen adult cadavers underwent three, 2-minute mechanical CPR trials per position in a counterbalanced crossover sequence. Solid-state catheters recorded pleural, peritoneal, and central arterial pressures simultaneously. Trial-level outcomes included peak pressure, mean pressure, pressure-time area, and the mean peritoneal-to-pleural pressure gradient. Exploratory fixed-effects models included position, cadaver, and their interaction. Results: Prone CPR increased peak intrathoracic pressure by 7.04 mmHg, peak intra-abdominal pressure by 21.69 mmHg, and peak arterial pressure by 15.40 mmHg. Mean intra-abdominal and arterial pressures increased by 16.22 and 9.90 mmHg, respectively. The mean peritoneal-to-pleural gradient reversed direction from -8.46 mmHg supine to 4.85 mmHg prone. Intrathoracic pressure-time area increased 3.4-fold, from 1.62 to 5.46 mmHg{middle dot}s, and arterial pressure-time area increased 2.2-fold, from 2.96 to 6.42 mmHg{middle dot}s. Conclusions: Compared to supine, prone mechanical CPR generated higher arterial pressures and reversed the pressure relationship across the thoracoabdominal boundary in both cadavers. Higher abdominal pressure coincided with a larger intrathoracic pressure-time area, a pattern compatible with reduced caudal pressure dissipation.

Genetic Variation, Iron Status, and FGF23 Signaling Converge to Regulate Renal Calcium Buffering in Sickle Cell Disease

Sickle cell disease (SCD) causes heterogeneous mineral imbalances including variable degrees of hypocalcemia. The kidney controls systemic calcium by reabsorbing calcium from the glomerular filtrate via paracellular transport and transcellular transport in the nephron tubules, yet it is unknown whether these processes are modulated by genetic or environmental factors or disrupted in SCD. Using SCD mouse models and single-cell multiomics, we identify the distal convoluted tubule (DCT) as the nephron segment most susceptible to calcium reabsorption dysfunction in SCD, mainly via reduction of calcium buffer protein calbindin 1 (CALB1). We show that CALB1 and its encoding mRNA are decreased in DCT cells in SCD, alongside decreased Klotho (KL)-dependent fibroblast growth factor (FGF) 23 signaling and intracellular calcium signaling. Dietary iron restriction reduces CALB1, KL, and calcium exporter SLC8A1 levels in SCD kidneys. Loss of CALB1 shifts DCT cells toward energy-inefficient glycolysis with the metabolite 2,3-diphosphoglycerate impairing KL-dependent FGF23 signaling to create a feed-forward loop suppressing calcium reabsorption. Analysis of gene expression and protein quantitative trait loci data from kidneys of genetically diverse mice revealed that Calb1 expression levels are highly heritable and co-regulated with Slc8a1, identifying a genetic axis that dictates differential capacities for calcium buffering and trafficking toward blood in the kidney. Together, these findings support a model in which genetic variation, dietary iron status, and FGF23 signaling converge on DCT calcium buffering to reduce renal calcium reabsorption in the SCD kidney. This points to personalized, genotype- and iron-dependent strategies for managing mineral metabolism in SCD patients.

Silver spoon effect: early-life environment and adult survival in a primate.

Early environmental conditions can have long-lasting effects on survival and reproductive fitness. Using a 23 year-long monitoring data set of captive mouse lemur's life history traits, we tested a relationship between maternal allocation to offspring (N = 1365) and their adulthood survival. Maternal characteristics such as age or body condition did not affect allocation to offspring whatever the litter size (1 to 3). Although birth mass depended on size and composition of the litters, mouse lemur survival was highly correlated with body mass acquired after weaning in both sexes, through potential sibling competition. Moreover, female's reproductive success correlated with this body mass and was consistently associated with increased longevity. These findings suggest the presence of a silver spoon effect under constant captive conditions. However, cumulative effects of genetic and adulthood social conditions strongly interact to affect adult survival. Deaths related to intra- or inter-sexes aggressive social interactions may outweigh effect of early environment and therefore minimize the silver-spoon effect on captive mouse lemur's survival. However, having a high body mass after weaning appeared to be a determinant factor in individual survival for mouse lemurs.
