How the COVID-19 pandemic shaped Canadians' preferences for setting of dying: Comparison of two panel surveys.

The purpose of this article is to assess whether COVID-19 shaped Canadians' preferred settings of dying. We compared data collected using the same survey from two independent but comparable sets of panel respondents, prior to and after the onset of the pandemic. A vignette methodology was used to assess preferences for dying in each of four settings: home, acute/intensive care, palliative care, and long-term residential care.

Mental Health Literacy Reduces the Impact of Internalized Stigma on Older Adults' Attitudes and Intentions to Seek Mental Health Services.

Objectives: Older adults are the least likely age group to seek mental health services, and internalized stigma is an important reason why. We sought to further our understanding of which older adults are particularly likely to be affected by internalized stigma, and why, by investigating mental health literacy (MHL) as a moderator within the internalized stigma model of help-seeking.

Methods: We utilized a conditional process analysis of cross-sectional, secondary data from 350 distressed older adults.

Social contributions to the foraging behavior of young wild golden lion tamarins (Leontopithecus rosalia): Age-related changes and partner preferences.

In cooperatively breeding species, group members other than the parents contribute to the care of the young. The costs and benefits to caregiving may vary with the type of care provided and with caregiver characteristics such as age, sex, reproductive status, and foraging ability. Here I examine the relative contributions of parents, helpers and same-aged twins to the foraging and feeding activities of the young in a longitudinal study of wild golden lion tamarins, specifically with regard to direct food transfer, tolerance for coforaging or cofeeding by immatures and signaling young as to the location of profitable prey-foraging sites.

Sibling sex, but not androgens, shapes phenotypes in perinatal common marmosets (Callithrix jacchus).

When offspring share a womb, interactions among fetuses can impart lasting impressions on phenotypic outcomes. Such intrauterine interactions often are mediated by sex steroids (estrogens and androgens) produced by the developing fetuses. In many mammals, intrauterine interactions between brothers and sisters lead to masculinization of females, which can induce fitness consequences.

Gene changes may minimize masculinizing and defeminizing influences of exposure to male cotwins in female callitrichine primates.

Background: Sexual differentiation in female mammals can be altered by the proximity of male littermates in utero, a phenomenon known as the intrauterine position effect (IUP). Among simian primates, callitrichines (marmosets and tamarins) are likely candidates for IUP, since they exhibit obligate dizygotic twinning and fetuses share extensive vascularization in utero. In this paper, we determined whether female reproductive parameters are altered by gestating with a male twin and evaluated changes in genes associated with anti-Müllerian and steroid hormones in twinning callitrichine primates.
