Associations of Traumatic Brain Injury and Mild Behavioral Impairment With Cognitive Function and Dementia.

Objective: Traumatic Brain Injury (TBI) may contribute additional complexity to the clinical picture of mild behavioral impairment (MBI). MBI, a behavioral analog to mild cognitive impairment (MCI), is comprised of five neuropsychiatric domains: decreased motivation, affective dysregulation, impulse dyscontrol, social inappropriateness, and abnormal perception/thought content. We investigated (1) if cross-sectional associations of cognitive status with MBI symptoms differ by TBI status and (2) if prospective associations of MBI domain positivity with incident dementia risk differ by TBI status.

Proteomics-based aging clocks in midlife and late-life and risk of dementia.

Biological age can be quantified by composite proteomic scores, called aging clocks. We investigated whether biological age acceleration (a discrepancy between chronological and biological age) in midlife and late-life is associated with cognitive function and risk of dementia. We used two population-based cohort studies: Atherosclerosis Risk in Communities (ARIC) Study and Multi-Ethnic Study of Atherosclerosis (MESA).

Finding My Way: Black Doulas' Communication with Other Birthing Care Providers in an Interprofessional Work Environment.

Black women suffer more complications and birthing harms compared to other race-ethnic groups. Even when birthing equity initiatives are implemented, many Black families choose to work with a Black doula to reduce harms linked to obstetric racism. Most Black doulas described their role as helping women have the kind of birth they want; however, problems doulas experience in communicating with other birthing team members are not well understood.

Klebsiella pneumoniae employs a type VI secretion system to overcome microbiota-mediated colonization resistance.

Microbial species must compete for space and nutrients to persist in the gastrointestinal (GI) tract, and our understanding of the complex pathobiont-microbiota interactions is far from complete. Klebsiella pneumoniae, a problematic, often drug-resistant nosocomial pathogen, can colonize the GI tract asymptomatically, serving as an infection reservoir. To provide insight on how K.
