The ability of bacteria to adapt to diverse environmental conditions is well-known. The process of bacterial adaptation to a niche has been linked to large changes in the genome content, showing that many bacterial genomes reflect the constraints imposed by their habitat. However, some highly versatile bacteria are found in diverse habitats that almost share nothing in common. Lactobacillus plantarum is a lactic acid bacterium that is found in a large variety of habitat. With the aim of unravelling the link between evolution and ecological versatility of L. plantarum, we analysed the genomes of 54 L. plantarum strains isolated from different environments. Comparative genome analysis identified a high level of genomic diversity and plasticity among the strains analysed. Phylogenomic and functional divergence studies coupled with gene-trait matching analyses revealed a mixed distribution of the strains, which was uncoupled from their environmental origin. Our findings revealed the absence of specific genomic signatures marking adaptations of L. plantarum towards the diverse habitats it is associated with. This suggests fundamentally similar trends of genome evolution in L. plantarum, which occur in a manner that is apparently uncoupled from ecological constraint and reflects the nomadic lifestyle of this species.

BMJ Open
January 2025
Zhengzhou University, Zhengzhou, Henan, China
Objectives: To investigate the association between social support and depressive symptoms among internal migrant workers with a focus on the mediating role of a healthy lifestyle.
Design: Cross-sectional study.
Setting: The research was conducted among internal migrant workers in Henan Province, China, in August 2023.

Background: Shifts in dietary patterns during lifestyle transitions are integral components of the dynamic interactions between humans and their environments. Investigating the link between dietary diversity, the composition of the human lipidome and infection is key to understanding the interplay between diet and susceptibility to pathogens.
Methods: Here we address this question by performing a comparative study of two ethnic groups with divergent dietary patterns: Fulani, who are nomad pastoralists with a dairy-centric diet, and Mossi, who are farmers with a plant-based diet.
Social Relational Notions of Successful Aging: Contesting Dominant Individualized Conceptions of Successful Aging By Examining Migrant Intergenerational Lived Experiences.
Gerontologist
December 2024
School of Arts and Humanities, Edith Cowan University, Perth, Western Australia, Australia.
Background And Objectives: Critiques of the concept of successful aging (SA) include attention to its foundation on an individualized western medical approach that emphasizes personal choice, agency, and lifestyle. This paper aims to examine how individual notions of SA can be linked to, and co-constituted by, relational and intergenerational notions of personhood within the broader socioeconomic, familial, and cultural contexts of migration.
Research Design And Methods: Qualitative research was conducted in Australia (2020-2021) with 42 Vietnamese migrants using ethnographic interviews and participant observation.
Health-related quality of life and its associated factors among Chinese seasonal retired migrants in Hainan.
PeerJ
November 2024
School of Public Health, Fudan University, Shanghai, China.
Background: Seasonal retired migrants are mainly retired or semiretired people who migrate to warmer areas during the winter and then return to their original homes in the following year. Despite its increasing popularity, the evidence concerning the health status of Chinese seasonal retired migrants is controversial. Although some studies have shown that seasonal retired migrants have better health status, other studies note that migrants are driven involuntarily by health concerns and that their mental health suffers during migration.

Previously, differences in the thyroid profile of Arctic residents were shown depending on the vitamin A blood level. However, dietary habits and metabolism peculiarities in the aboriginal and Caucasian representatives of the North population may be the cause of different retinol supply and therefore be one of the reasons for changes in their thyroid activity. of the research was to assess vitamin A and thyroid blood levels in the aboriginal and local Caucasian population representatives of the Russian Arctic territories.
