Estudo chileno revela sintomas de depressão em galinhas confinadas

Uma pesquisa liderada pela Dra. Javiera Calderón descobriu que galinhas criadas em gaiolas tradicionais apresentam pelo menos dois comportamentos comparáveis à depressão clínica.

O estudo, publicado nas revistas Animal Welfare e Applied Animal Behaviour Science, comparou galinhas em gaiolas com aves em ambientes livres. Noventa por cento das galinhas poedeiras do Chile vivem em gaiolas tradicionais. A Dra. Calderón, veterinária da Universidad de Chile e doutora pela UACh, afirmou que os resultados evidenciam um grave problema ético. "Isso nos mostra um profundo problema de bem-estar", disse ela. Uma segunda linha de pesquisa demonstrou que as galinhas formam laços positivos com humanos quando tratadas com delicadeza. As descobertas foram divulgadas recentemente.

A study of 440 participants from the Women’s Interagency HIV Study found that accelerated epigenetic aging in monocytes—an immune cell type—tracked more closely with emotional and cognitive depression symptoms such as hopelessness and loss of pleasure than with physical symptoms like fatigue. The work, published in The Journals of Gerontology: Series A, adds evidence that cell-type-specific aging measures could contribute to future biological tools to complement symptom-based depression screening, though researchers say more validation is needed before clinical use.
