Difference in mean systolic BP change from baseline to 18 months is the primary clinical effectiveness outcome, and intervention fidelity, measured by treatment intensification and medication adherence, is the primary implementation outcome. The planned sample size of 1,260 participants (36 clinics with 35 participants each) has 90% power to detect a 5.0-mm Hg difference in systolic BP at a .05 significance level and 80% follow-up rate. IMPACTS will generate critical data on the effectiveness and implementation of a multifaceted intervention for intensive BP treatment in real-world clinical practice and could directly impact the BP-related disease burden in minority and low-income populations in the United States.

Here we identified conserved non-coding sequences (CNSs) 6 and 9 at the Rorc gene, essential for its expression during Th17 cell differentiation but not required for RORγt expression in innate lymphocytes and γδ T cells. Mechanistically, the IL-6-signal transducer and activator of transcription 3 (STAT3) axis appeared to be largely dependent on CNS9 and only partially on CNS6 in controlling RORγt expression and epigenetic activation of the Rorc locus. TGF-β alone was sufficient to induce RORγt expression in a CNS6- but not CNS9-dependent manner through CNS6 binding by SMAD proteins. Our study reveals an important synergistic mechanism downstream of IL-6 and TGF-β in regulation of RORγt expression and Th17 cell commitment via distinct cis-regulatory elements.The representation of odor in olfactory cortex (piriform) is distributive and unstructured and can only be afforded behavioral significance upon learning. We performed 2-photon imaging to examine the representation of odors in piriform and in two downstream areas, the orbitofrontal cortex (OFC) and the medial prefrontal cortex (mPFC), as mice learned olfactory associations. In piriform, we observed that odor responses were largely unchanged during learning. In OFC, 30% of the neurons acquired robust responses to conditioned stimuli (CS+) after learning, and these responses were gated by internal state and task context. Moreover, direct projections from piriform to OFC can be entrained to elicit learned olfactory behavior. CS+ responses in OFC diminished with continued training, whereas persistent representations of both CS+ and CS- odors emerged in mPFC. Optogenetic silencing indicates that these two brain structures function sequentially to consolidate the learning of appetitive associations.During development, endothelial tip cells (ETCs) located at the leading edge of growing vascular plexus guide angiogenic sprouts to target vessels, and thus, ETC pathfinding is fundamental for vascular pattern formation in organs, including the brain. However, mechanisms of ETC pathfinding remain largely unknown. Here, we report that Piezo1-mediated Ca2+ activities at primary branches of ETCs regulate branch dynamics to accomplish ETC pathfinding during zebrafish brain vascular development. ETC branches display spontaneous local Ca2+ transients, and high- and low-frequency Ca2+ transients cause branch retraction through calpain and branch extension through nitric oxide synthase, respectively. These Ca2+ transients are mainly mediated by Ca2+-permeable Piezo1 channels, which can be activated by mechanical force, and mutating piezo1 largely impairs ETC pathfinding and brain vascular patterning. These findings reveal that Piezo1 and downstream Ca2
