Examining Knowledge and Attitudes Regarding Social Determinants Among Nursing Students Following Immersive Virtual Reality Simulation: A Descriptive Study.

This quantitative descriptive study explored the impact of virtual reality (VR) simulation on nursing students' understanding of social determinants of health (SDOH). The study assessed students' knowledge and attitudes toward SDOH after participating in VR simulations that mimicked diverse home environments and client scenarios. The intervention was intended to prepare future nurses for practice in diverse community settings and deepen their understanding of community challenges, particularly those impacted by socioeconomic disparities.

Modulation of antigen delivery and lymph node activation in nonhuman primates by saponin adjuvant saponin/monophosphoryl lipid A nanoparticle.

Saponin-based vaccine adjuvants are potent in preclinical animal models and humans, but their mechanisms of action remain poorly understood. Here, using a stabilized HIV envelope trimer immunogen, we carried out studies in nonhuman primates (NHPs) comparing the most common clinical adjuvant aluminum hydroxide (alum) with saponin/monophosphoryl lipid A nanoparticles (SMNP), an immune-stimulating complex-like adjuvant. SMNP elicited substantially stronger humoral immune responses than alum, including 7-fold higher peak antigen-specific germinal center B-cell responses, 18-fold higher autologous neutralizing antibody titers, and higher levels of antigen-specific plasma and memory B cells.

Evaluation of a non-nucleoside inhibitor of the RSV RNA-dependent RNA polymerase in translatable animals models.

Respiratory Syncytial Virus (RSV) causes severe respiratory infections and concomitant disease resulting in significant morbidity and mortality in infants, elderly, and immunocompromised adults. Vaccines, monoclonal antibodies, and small-molecule antivirals are now either available or in development to prevent and treat RSV infections. Although rodent and non-rodent preclinical animal models have been used to evaluate these emerging agents, there is still a need to improve our understanding of the pharmacokinetic (PK)-pharmacodynamic (PD) relationships within and between animal models to enable better design of human challenge studies and clinical trials.

Modulation of antigen delivery and lymph node activation in non-human primates by saponin adjuvant SMNP.

Saponin-based vaccine adjuvants are potent in preclinical animal models and humans, but their mechanisms of action remain poorly understood. Here, using a stabilized HIV envelope trimer immunogen, we carried out studies in non-human primates (NHPs) comparing the most common clinical adjuvant alum with Saponin/MPLA Nanoparticles (SMNP), a novel ISCOMs-like adjuvant. SMNP elicited substantially stronger humoral immune responses than alum, including 7-fold higher peak antigen-specific germinal center B cell responses, 18-fold higher autologous neutralizing antibody titers, and higher levels of antigen-specific plasma and memory B cells.

A randomized comparative-effectiveness study of two enhanced prenatal care models for low-income pregnant people: Engaging Mothers & Babies; Reimagining Antenatal Care for Everyone (EMBRACE).

Background: Improving perinatal mental health and care experiences and preventing adverse maternal and infant outcomes are essential prenatal care components, yet existing services often miss the mark, particularly for low-income populations. An enhanced group prenatal care program, "Glow! Group Prenatal Care and Support," was developed in California's Central Valley in response to poor perinatal mental health, disrespectful care experiences, and high rates of adverse birth outcomes among families with low incomes.

Methods: Engaging Mothers & Babies; Reimagining Antenatal Care for Everyone (EMBRACE) is a pragmatic, two-arm, randomized, comparative-effectiveness study designed to assess depression (primary outcome), the experience of care (secondary outcome), and preterm birth (exploratory outcome) among Medi-Cal (California's Medicaid program)-eligible pregnant and birthing people, comparing those assigned to Glow! Group Prenatal Care and Support (Glow/GC) with those assigned to enhanced, individual prenatal care through the California Department of Public Health's Comprehensive Perinatal Services Program (CPSP/IC).
