Comment Welcome to small town America (Score 1) 273

by wal (#63110460) Attached to: Remote Work Is Gutting Downtowns, Will Cost Cities $453 Billion

As someone who moved from a small midwestern town to the suburbs of a large city during the pandemic, I envision larger cities continuing to mimic small town America where people go for evening entertainment and social gatherings. Stadiums and auditoriums have been moving "back" downtown from the suburbs for a while now. I picture revenue moving from lunch venues to evening drinks and show. When people have no real reason to go downtown, you need to create a reason. I feel this has been happening for years now (gentrification), the pandemic has just hastened it along and cities need to move even more quickly and adapt to survive.

Gut Bacteria Are Linked To Depression (wsj.com) 86

Posted by BeauHD from the you-are-what-you-eat dept.
Two studies published Tuesday in the journal Nature Communications found a link between several types of bacteria in the gut and depressive symptoms. The first study, titled "Gut microbiome-wide association study of depressive symptoms," reports: Here we investigate the relation of fecal microbiome diversity and composition with depressive symptoms in 1,054 participants from the Rotterdam Study cohort and validate these findings in the Amsterdam HELIUS cohort in 1,539 subjects. We identify association of thirteen microbial taxa, including genera Eggerthella, Subdoligranulum, Coprococcus, Sellimonas, Lachnoclostridium, Hungatella, Ruminococcaceae (UCG002, UCG003 and UCG005), LachnospiraceaeUCG001, Eubacterium ventriosum and Ruminococcusgauvreauiigroup, and family Ruminococcaceae with depressive symptoms. These bacteria are known to be involved in the synthesis of glutamate, butyrate, serotonin and gamma amino butyric acid (GABA), which are key neurotransmitters for depression. Our study suggests that the gut microbiome composition may play a key role in depression. The second study, titled "The gut microbiota and depressive symptoms across ethnic groups," reports: Both the microbiome and depressive symptom levels vary substantially across ethnic groups. Thus, any intervention for depression targeting the microbiome requires understanding of microbiome-depression associations across ethnicities. Analyzing data from the HELIUS cohort, we characterize the gut microbiota and its associations with depressive symptoms in 6 ethnic groups (Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Turkish, Moroccan; N=3211), living in the same urban area. Diversity of the gut microbiota, both within (a-diversity) and between individuals (B-diversity), predicts depressive symptom levels, taking into account demographic, behavioural, and medical differences. These associations do not differ between ethnic groups. Further, B-diversity explains 29%-18% of the ethnic differences in depressive symptoms. Bacterial genera associated with depressive symptoms belong to mulitple families, prominently including the families Christensenellaceae, Lachnospiraceae, and Ruminococcaceae. In summary, the results show that the gut microbiota are linked to depressive symptom levels and that this association generalizes across ethnic groups. Moreover, the results suggest that ethnic differences in the gut microbiota may partly explain parallel disparities in depression. The Wall Street Journal shared (paywalled) the findings.
