Nasal CPAP increases alveolar number in a rhesus monkey model of moderate prematurity.

Rationale: Most premature human infants are born in the moderate to late preterm (MLP) range, ≥30 to <37 weeks gestation and demonstrate increased incidence of wheeze and respiratory illness as they age. Animal models suggest that mechanical lung distention stimulates lung growth and alveolar development. To determine if nasal continuous positive airway pressure (nCPAP) influences MLP infant lung development, we developed a rhesus monkey model of moderate prematurity, randomized to 9 days of nCPAP or sham nCPAP.

Re-politicizing the WHO's social determinants of health framework.

Although the World Health Organization's (WHO's) framework on social and structural determinants of health and health inequities (SSDHHI) has done much to raise awareness of these determinants, it does not go far enough in considerations of politics and power. The framework has become more de-politicized since its publication, with the definition of social determinants shifting toward downstream and individualized factors. In the meantime, new research fields on legal, commercial and political determinants of health and health inequities have emerged; however, these have not become integrated adequately into broader SSDHHI frameworks.

Microsporidian coinfection reduces fitness of a fungal pathogen due to rapid host mortality.

Infection outcomes can be strongly context dependent, shifting a host-symbiont relationship along a parasitism-mutualism continuum. Numerous studies show that under stressful conditions, symbionts that are typically mutualistic can become parasitic. The reverse possibility, a parasite becoming mutualistic, has received much less study.

Phylogeny, morphology, virulence, ecology, and host range of (Ordosporidae), a microsporidian symbiont of spp.

Unlabelled: The impacts of microsporidia on host individuals are frequently subtle and can be context dependent. A key example of the latter comes from a recently discovered microsporidian symbiont of , the net impact of which was found to shift from negative to positive based on environmental context. Given this, we hypothesized low baseline virulence of the microsporidian; here, we investigated the impact of infection on hosts in controlled conditions and the absence of other stressors.

Is fair representation good for children? effects of electoral partisan bias in state legislatures on policies affecting children's health and well-being.

Increasing evidence suggests that state policies impact constituents' health, but political determinants of health and health inequities remain understudied. Using state and year fixed-effects models, we determined the extent to which changes in electoral partisan bias in lower chambers of U.S.
