Client perspectives on primary care integration in a rural-serving behavioral health center.

Purpose: Advancing behavioral health and primary care integration is a priority for helping clients overcome the complex health challenges impacting healthcare deserts like those in Arizona, United States of America (USA). This study aimed to explore the perspectives of people with a substance use disorder (SUD) on accessing integrated primary care (IPC) services in a rural-serving behavioral healthcare organization in Arizona. Design/methodology/approach: Clients from a behavioral health facility in Arizona (n = 10) diagnosed with SUDs who also accessed IPC participated in a 45-min semi-structured interview. Findings: The authors identified six overarching themes: (1) importance of IPC for clients being treated for SUDs, (2) client low level of awareness of IPC availability at the facility, (3) strategies to increase awareness of IPC availability at the behavioral health facility, (4) cultural practices providers should consider in care integration, (5) attitudes and perceptions about the experience of accessing IPC and (6) challenges to attending IPC appointments. The authors also identified subthemes for most of the main themes. Originality/value: This is the first study in rural Arizona to identify valuable insights into the experiences of people with SUDs accessing IPC, providing a foundation for future research in the region on care integration.

Outcomes of social class and classism in first- and continuing-generation college students.

The purpose of this study was to examine perceptions of classism that may explain links between social class, first-generation college student status, and academic and well-being outcomes. Specifically, with a sample of 1,225 college students from a public university, we examined social class and first-generation status as predictors of institutionalized, citational, and interpersonal classism and classism as a predictor of life satisfaction, academic satisfaction, and grade point average (GPA). Partially supporting hypotheses, social class and first-generation status predicted institutionalized classism and interpersonal classism, and social class predicted citational classism. In turn, institutionalized classism and citational classism negatively predicted life satisfaction, and institutionalized classism negatively predicted academic satisfaction. Indirect effects were significant from social class to life satisfaction via institutionalized and citational classism, from social class to academic satisfaction via institutionalized classism, and from first-generation status to life satisfaction via institutionalized classism. Social class also had direct effects to life satisfaction, academic satisfaction, and GPA, and first-generation status had direct effects to academic satisfaction and GPA. Implications for research and practice are discussed. (PsycINFO Database Record

Site-targeted complement inhibition by a complement receptor 2-conjugated inhibitor (mTT30) ameliorates post-injury neuropathology in mouse brains.

Intracerebral complement activation after severe traumatic brain injury (TBI) leads to a cascade of neuroinflammatory pathological sequelae that propagate host-mediated secondary brain injury and adverse outcomes. There are currently no specific pharmacological agents on the market to prevent or mitigate the development of secondary cerebral insults after TBI. A novel chimeric CR2-fH compound (mTT30) provides targeted inhibition of the alternative complement pathway at the site of tissue injury. This experimental study was designed to test the neuroprotective effects of mTT30 in a mouse model of closed head injury. The administration of 500 µg mTT30 i.v. at 1 h, 4 h and 24 h after head injury attenuated complement C3 deposition in injured brains, reduced the extent of neuronal cell death, and decreased post-injury microglial activation, compared to vehicle-injected placebo controls. These data imply that site-targeted alternative pathway complement inhibition may represent a new promising therapeutic avenue for the future management of severe TBI.

Serum biomarkers for traumatic brain injury.

There is a lack of reliable serum biomarkers for routine use in the diagnostic workup of people with traumatic brain injury. Multiple biomediators and biomarkers have been described in the pertinent literature in recent years; however, only a few candidate molecules have been associated with high sensitivity and high specificity for risk stratification and outcome prediction after traumatic brain injury. This review was designed to provide an overview of the state of the art regarding established serum biomarkers in the field and to outline future directions of investigation.

Deficiency of complement receptors CR2/CR1 in Cr2⁻/⁻ mice reduces the extent of secondary brain damage after closed head injury.

Complement activation at the C3 convertase level has been associated with acute neuroinflammation and secondary brain injury after severe head trauma. The present study was designed to test the hypothesis that Cr2-/- mice, which lack the receptors CR2/CD21 and CR1/CD35 for complement C3-derived activation fragments, are protected from adverse sequelae of experimental closed head injury. Adult wild-type mice and Cr2-/- mice on a C57BL/6 genetic background were subjected to focal closed head injury using a standardized weight-drop device. Head-injured Cr2-/- mice showed significantly improved neurological outcomes for up to 72 hours after trauma and a significantly decreased post-injury mortality when compared to wild-type mice. In addition, the Cr2-/- genotype was associated with a decreased extent of neuronal cell death at seven days post-injury. Western blot analysis revealed that complement C3 levels were reduced in the injured brain hemispheres of Cr2-/- mice, whereas plasma C3 levels remained unchanged, compared to wild-type mice. Finally, head-injured Cr2-/- had an attenuated extent of post-injury C3 tissue deposition, decreased astrocytosis and microglial activation, and attenuated immunoglobulin M deposition in injured brains compared to wild-type mice. Targeting of these receptors for complement C3 fragments (CR2/CR1) may represent a promising future approach for therapeutic immunomodulation after traumatic brain injury.
