The potential impact of optimal blood pressure treatment intensity to reduce disparities in dementia between Black and White individuals.

Background: Black adults have higher dementia risk than White adults. Whether tighter population-level blood pressure (BP) control reduces this disparity is unknown.

Objective: Estimate the impact of optimal BP treatment intensity on racial disparities in dementia.

Approach to the Diagnosis and Management of Complex Fascicular Ventricular Tachycardias.

Complex ventricular tachycardias involving the fascicular system (fascicular ventricular tachycardias [FVTs]) can be challenging. In this review, we describe our approach to the diagnosis and ablation of these arrhythmias with 10 illustrative cases that involve (1) differentiation from supraventricular tachycardia; (2) assessment for atypical bundle branch reentry and other interfascicular FVTs; (3) examination of P1/P2 activation sequences in sinus rhythm, pacing, and tachycardia; and (4) entrainment techniques to establish the tachycardia mechanism and aid circuit localization. To summarize, 5 cases had prior ablation with 2 previously misdiagnosed as supraventricular tachycardia.

All-optical mapping of Ca transport and homeostasis in dendrites.

Calcium mediates many important signals in dendrites. However, the basic transport properties of calcium in dendrites have been difficult to measure: how far and how fast does a local influx of calcium propagate? We developed an all-optical system for simultaneous targeted Ca import and Ca concentration mapping. We co-expressed a blue light-activated calcium selective channelrhodopsin, CapChR2, with a far-red calcium sensor, FR-GECO1c, in cultured rat hippocampal neurons, and used patterned optogenetic stimulation to introduce calcium into cells with user-defined patterns of space and time.

The Snails: A Simple Technique for Reduction of Frontal Bossing in Children With Scaphocephaly.

Objective: Scaphocephaly represents the most frequent single-suture craniosynostosis, with a male prevalence. In many cases, prominent frontal bossing (sphenocephaly) is the major aesthetic concern, typically in school-aged children. This aspect is also usually found in patients with late presentation (after 1 year of age).

Mapping vulnerability to climate-related hazards to inform local authority action in adaptation: A feasibility study.

Background: Local authorities have a crucial role in building community resilience to the health effects of a changing climate. Support in achieving local action can be provided through improving available public health intelligence to inform decision making. We aimed to co-develop with a local authority a tool mapping vulnerability to climate related hazards.
