Personality disorders and related healthcare use among older United States veterans experiencing housing instability and homelessness, 2016-2024
Veterans are vulnerable to housing instability and/or homelessness (HUH) and may encounter unique challenges that affect their healthcare. While research has noted connections between major psychiatric disorders and HUH, few studies have examined personality disorders (PD) and their sex-specific relationships with HUH and healthcare use among aging veterans. We examined sex differences in the epidemiology of PD and their impact on healthcare service use among aging HUH veterans. A...

Imaging the neurohiv brain in animal models: past, present, and future-toward longitudinal, whole-brain aging phenotypes
Animal models are essential for defining mechanisms of HIV-associated brain injury in the antiretroviral therapy era, where neurocognitive impairment and brain aging have replaced opportunistic infections as dominant clinical concerns. Humanized mice, EcoHIV murine systems, and SIV or SHIV nonhuman primates now enable increasingly sophisticated brain imaging across in vivo and ex vivo scales. Structural and diffusion MRI, perfusion imaging, manganese-enhanced MRI, and multiphoton and endoscopic...
The Construct Validity of the Life-Space Assessment in the Canadian Longitudinal Study on Aging (CLSA)
CONCLUSION: The LSA can be used to differentiate between known groups. However, there is limited evidence of its convergent validity as its relationship with other measures of actual mobility, perceived mobility, and locomotor capacity for mobility was weak. Future studies need to assess the convergent validity of the LSA against different comparator measures before its use among community-dwelling Canadians.

Scientists finally solved how a common gut bacterium triggers colon cancer
Researchers solved a long-standing mystery behind how a bacterial toxin associated with colorectal cancer damages the colon. The toxin first binds to a receptor called claudin-4, giving it access to attack the cells' protective barrier. After identifying this weak point, the team designed a decoy protein that successfully blocked the toxin in mice. The discovery could pave the way for new therapies to prevent inflammation and colon tumors.
