How to design and implement a Group Poem activity.

Museum-based learning activities provide interactive and innovative ways to integrate the arts and humanities into medical education. Like other museum-based activities, the Group Poem supports the development of multiple clinically relevant skills and attributes, such as observation, communication, perspective-taking, empathy, and implicit bias awareness. In this paper, we present a step-by-step guide for educators seeking to design and implement a museum-based Group Poem activity for medical learners. The overall 'task' of the activity is for learners to collectively create a poem that they perform for others, a process that participants find to be engaging and meaningful to their formation as physicians. In this paper, we provide specific directions on pre-selecting the works of art, preparing the supplies, dividing into small groups, providing iterative instructions to learners, managing the timing of the session, and debriefing the activity. Although designed to be experienced in an art museum, we note that the Group Poem activity can also be conducted in the classroom or virtually using photographic or digital reproductions of artwork.

Acute dietary nitrate supplementation does not augment submaximal forearm exercise hyperemia in healthy young men.

Despite the popularity of dietary nitrate supplementation and the growing evidence base of its potential ergogenic and vascular health benefits, there is no direct information about its effects on exercising limb blood flow in humans. We hypothesized that acute dietary nitrate supplementation from beetroot juice would augment the increases in forearm blood flow, as well as the progressive dilation of the brachial artery, during graded handgrip exercise in healthy young men. In a randomized, double-blind, placebo-controlled crossover study, 12 young (22 ± 2 years) healthy men consumed a beetroot juice (140 mL Beet-It Sport, James White Juice Company) that provided 12.9 mmol (0.8 g) of nitrate or placebo (nitrate-depleted Beet-It Sport) on 2 study visits. At 3 h postconsumption, brachial artery diameter, flow, and blood velocity were measured (Doppler ultrasound) at rest and during 6 exercise intensities. Nitrate supplementation raised plasma nitrate (19.5-fold) and nitrite (1.6-fold) concentrations, and lowered resting arterial pulse wave velocity (PWV) versus placebo (all p < 0.05), indicating absorption, conversion, and a biological effect of this supplement. The supplement-associated lowering of PWV was also negatively correlated with plasma nitrite (r = -0.72, p = 0.0127). Despite these systemic effects, nitrate supplementation had no effect on brachial artery diameter, flow, or shear rates at rest (all p ≥ 0.28) or during any exercise workload (all p ≥ 0.18). These findings suggest that acute dietary nitrate supplementation favorably modifies arterial PWV, but does not augment blood flow or brachial artery vasodilation during nonfatiguing forearm exercise in healthy young men.
