The Relationship between Religion, Substance Misuse, and Mental Health among Black Youth.

Studies suggest that religion is a protective factor for substance misuse and mental health concerns among Black/African American youth despite reported declines in their religious involvement. However, few studies have investigated the associations among religion, substance misuse, and mental health among Black youth. Informed by Critical Race Theory, we evaluated the correlations between gender, depression, substance misuse, and unprotected sex on mental health. Using multiple linear regression, we assessed self-reported measures of drug use and sex, condom use, belief in God, and religiosity on mental health among a sample of Black youth (N = 638) living in a large midwestern city. Results indicated drug use, and sex while on drugs and alcohol, were significant and positively associated with mental health symptoms. Belief in God was negatively associated with having sex while on drugs and alcohol. The study's findings suggest that despite the many structural inequalities that Black youth face, religion continues to be protective for Black youth against a myriad of prevalent problem behaviors.

Evaluation of biochars as carriers for Rhizobium leguminosarum.

Peat is the standard carrier material used for commercial microbial inoculants produced in Canada and the United States. Peat is a slowly renewable resource and its production is extremely vulnerable to variable weather conditions. Furthermore, it may not be widely available in all countries. We investigated the potential to develop biochar as a carrier material. Our goal was to evaluate if different biochars perform comparably in supporting rhizobial survival, and what characteristics contribute to their ability to support rhizobial survival. Evaluation included characterization of the biochars, assessment of biochar phytotoxicity, survival of Rhizobium on biochars, and growth chamber evaluation of two biochars as Rhizobium carriers for inoculating pea. Of the original nine biochars evaluated, six supported Rhizobium leguminosarum for 84 days at 4 °C; of this six, two supported numbers >1 × 106 cfu·(g biochar)-1. The only characteristics that correlated with survival were C/N ratio and percent C. The two biochars evaluated delivered R. leguminosarum to pea that initiated nodulation, biomass production, and biomass N at levels higher than a noninoculated control and heat-killed inoculated biochars. We demonstrate that there is considerable potential to develop biochar as a carrier for rhizobial inoculants.

Intravascular Ultrasound Imaging Versus Digital Subtraction Angiography in Patients with Peripheral Vascular Disease.

OBJECTIVES: The evaluation of arterial plaque morphology and vessel diameter is a vital component of peripheral vascular interventions. Historically, digital subtraction angiography (DSA) has been considered the gold standard for vessel sizing and treatment. However, this modality has the limitation of providing a two-dimensional image of a three-dimensional luminal structure. Utilization of intravascular ultrasound (IVUS) has been incorporated into diagnostic and treatment algorithms to further characterize the arterial vessel. This study compared visual estimation of vessel diameter by angiographic imaging with IVUS measurements. METHODS: A retrospective analysis was conducted on a cohort of 43 patients who underwent an endovascular intervention utilizing DSA and IVUS imaging. Angiographic measurements were determined by an interventionalist blinded to the IVUS findings. RESULTS: Of the 43 patients, 58% were male, the majority (72%) were ages 60-89 years, 58% were Rutherford classification III, and 42% had critical limb ischemia (Rutherford classification IV or V). Arterial access sites were common femoral, posterior tibial, and anterior tibial in 37%, 37%, and 26%, respectively. Tibiopedal arterial minimally invasive (TAMI) retrograde revascularization was utilized in 63% of patients. Vessel sizing was consistently the same or smaller for female subjects with either imaging modality. Overall, measurements estimated from angiographic images were significantly smaller than those obtained from IVUS analysis. CONCLUSION: IVUS appears to offer a greater degree of accuracy in measuring arterial lumen diameter. As measurements obtained from angiographic imaging consistently under-estimated vessel size, utilization of IVUS may aid in the determination of treatment algorithms and lead to improved endovascular outcomes.

Making Breast Cancer (Black) History: Results of a Church-Based Primary Prevention Study.

Breast cancer rates for African American women are lower than that of their White peers, yet their mortality rate is disproportionately higher. This study sought to address the disparity through a community-based primary prevention study targeting African American women in the Black church utilizing the public health model of primary, secondary, and tertiary prevention. The study centered on the meaningful intersection of race, gender, and faith as key factors in increasing breast health knowledge and breast cancer risk factors. The results reveal that African American women respond positively to intervention models centered on salient aspects of their identity.
