Black mothers' ethnic-racial socialization one year after highly publicized anti-Black murders during the pandemic.

Although research on ethnic-racial socialization is well established, limited studies have examined the influence of specific, highly publicized anti-Black murders. We assessed Black mothers' (N = 12, mean age = 37.45) concerns and ethnic-racial socialization with adolescents aged 11-18 years old approximately 1 year following the murders of George Floyd and other unarmed Black people. Researchers generated the following themes using reflexive thematic analysis: protecting adolescents from physical harm; protecting adolescents from psychological harm; parents' emotional distress; and parents' lack of confidence in their ethnic-racial socialization practices. Black mothers exhibit exceptional amounts of strength and courage as they navigate pervasive physical and psychological threats to their adolescents while experiencing worry and low confidence in their ability to socialize their adolescents about anti-Black racism.

"It's Important to Work with People that Look Like Me": Black Patients' Preferences for Patient-Provider Race Concordance.

A compelling body of research supports the race concordance hypothesis, which asserts that racially minoritized patients who share the same race and ethnicity with their provider have improved communication, better perceptions of care, and better health outcomes. Using a mixed methods approach, this study examined (1) the association between racial identity and patients' preference for race-concordant patient-provider dyads and (2) Black patients' subjective experiences of race concordance. Data were gathered from 47 Black caregivers who completed both a survey and participated in a focus group. Quantitative analyses revealed that the majority (83%) of caregivers reported that it is important to have a mental health provider of the same race and ethnicity. Greater racial centrality, but not private or public regard, was associated with a stronger race concordance preference. Thematic analysis of qualitative data revealed six themes related to race-concordant preferences: aspects related to the patient care experience, cultural humility, relatability, diversity in cultural experiences, role models for children, and intersecting identities. Patients with a race concordance preference felt more comfortable with their provider, perceived that it was easier to build a rapport with their provider, and emphasized the value of representation for themselves and their children. Patients who were neutral in their race concordance preference emphasized professionalism over race, valued diverse perspectives, and appreciated their providers' cultural awareness and willingness to self-educate. The integration of these findings will help to elucidate a more nuanced understanding of the factors that build the therapeutic relationship and cultivate a framework of comfort and understanding in the clinical setting.

Butyric Acid Generation by Clostridium tyrobutyricum from Low-Moisture Anhydrous Ammonia (LMAA) Pretreated Sweet Sorghum Bagasse.

Sweet sorghum bagasse (SSB) is an under-utilized feedstock for biochemical conversion to biofuels or high value chemicals. One such chemical that can be generated biochemically and applied to a wide array of industries from pharmaceuticals to the production of liquid transportation fuels is butyric acid. This work investigated cultivating the butyric acid producing strain Clostridium tyrobutyricum ATCC 25755 on low-moisture anhydrous ammonia (LMAA) pretreated SSB. Pretreated SSB hydrolysate was detoxified and supplemented with urea for shake flask batch fermentation to show that up to 11.4 g/L butyric acid could be produced with a selectivity of 87% compared to other organic acids. Bioreactor fermentation with pH control showed high biomass growth, but a similar output of 11.3 g/L butyric acid was achieved. However, the butyric acid productivity increased to 0.251 g/L∙hr with a butyric acid yield of 0.29 g/g sugar consumed. This butyric acid output represented an 83% theoretical yield. Further improvements in butyric acid titer and yield can be achieved by optimizing nutrient supplementation and incorporating fed-batch fermentation processing of pretreated SSB hydrolysate.
