Background: Hackathons are organized to bring together both experienced and novice individuals from a variety of backgrounds to brainstorm creative solutions to complex issues. Hackathons may last from a few hours to a few days and may provide rewards for winning entries.

Purpose: In this article, we describe an experience with a scientific hackathon at an international nursing research congress in Calgary, Canada.

The Tribal Tobacco Education and Policy Initiative: Findings From a Collaborative, Participatory Evaluation.

While the reduction in the overall U.S. smoking prevalence has been declared one of the top 10 public health achievements of the past century, the growing disparity in smoking between American Indians and the general population is one of the biggest challenges of the 21st century.

Health Literacy Education in Baccalaureate Nursing Programs in the United States.

Aim: This study's aim was to determine the prevalence of health literacy education in nursing programs. Health literacy content and teaching strategies were also explored.

Background: Over 75 million Americans have low health literacy, a problem that can cause negative health outcomes.

Why the World Will Never Be Tobacco-Free: Reframing "Tobacco Control" Into a Traditional Tobacco Movement.

As successes mount in reducing commercial tobacco use, an alarming disparity has taken shape in Minnesota. Recent studies revealed that overall smoking rates have dropped to 14%, whereas American Indians' rates remain higher than 50%. With support from ClearWay Minnesota, the organization created from the state's tobacco settlement, advocates working within sovereign tribal governments to create smoke-free policies came together to discuss effective strategies within tribal Nations.

Engaging health systems to increase colorectal cancer screening: community-clinical outreach in underserved areas of Wisconsin.

Background: Colorectal cancer is the fourth most commonly diagnosed cancer and the second leading cause of cancer-related death in Wisconsin. Incidence and mortality rates for colorectal cancer vary by age, race/ethnicity, geography, and socioeconomic status. From 2010 through 2012, the Wisconsin Comprehensive Cancer Control Program awarded grants to 5 regional health systems for the purpose of planning and implementing events to increase colorectal cancer screening rates in underserved communities.

A case study in teaching tobacco policy advocacy at a Historically Black university.

Policy advocacy is increasingly recognized as a crucial component of the training provided to health educators but relatively few universities offer advocacy training as part of their professional preparation programs for health educators. Historically Black colleges and universities (HBCUs) represent a natural setting for creating strong Black leaders in tobacco policy advocacy. This case study focuses on experiential education at an HBCU to develop advocacy skills around tobacco issues among Black college students.

Retinoid signaling is involved in governing the waiting period for axons in chick hindlimb.

During embryonic development in chick, axons pause in a plexus region for approximately 1 day prior to invading the limb. We have previously shown that this "waiting period" is governed by maturational changes in the limb. Here we provide a detailed description of the spatiotemporal pattern of Raldh2 expression in lumbosacral motoneurons and in the limb, and show that retinoid signaling in the limb contributes significantly to terminating the waiting period.

Informing best practice with community practice: the community change chronicle method for program documentation and evaluation.

Health promotion professionals are increasingly encouraged to implement evidence-based programs in health departments, communities, and schools. Yet translating evidence-based research into practice is challenging, especially for complex initiatives that emphasize environmental strategies to create community change. The purpose of this article is to provide health promotion practitioners with a method to evaluate the community change process and document successful applications of environmental strategies.

Shh influences cell number and the distribution of neuronal subtypes in dorsal root ganglia.

The molecular mechanisms responsible for specifying the dorsal-ventral pattern of neuronal identities in dorsal root ganglia (DRG) are unclear. Here we demonstrate that Sonic hedgehog (Shh) contributes to patterning early DRG cells. In vitro, Shh increases both proliferation and programmed cell death (PCD).

Hoxc10 and Hoxd10 regulate mouse columnar, divisional and motor pool identity of lumbar motoneurons.

A central question in neural development is how the broad diversity of neurons is generated in the vertebrate CNS. We have investigated the function of Hoxc10 and Hoxd10 in mouse lumbar motoneuron development. We show that Hoxc10 and Hoxd10 are initially expressed in most newly generated lumbar motoneurons, but subsequently become restricted to the lateral division of the lateral motor column (lLMC).

Onset of ETS expression is not accelerated by premature exposure to signals from limb mesenchyme.

The ETS transcription factors ER81 and PEA3 are expressed in discrete populations of sensory and motor neurons and regulate late events in neuronal development and limb innervation. Although initiation of ETS expression requires limb-derived signals, we show here that precocious axon growth into transplanted older donor limbs, which prematurely exposes neurons to limb-derived signals, does not accelerate the onset of expression of Er81 or Pea3. Similarly, neither MN-cadherin, which is reportedly regulated by ER81, nor T-cadherin is expressed precociously in neurons innervating older donor limbs.

Smoking rates among American Indian women giving birth in Minnesota. A call to action.

Maternal smoking is associated with a number of adverse effects including neonatal mortality, preterm delivery, low birth weight, decreased lung growth and function, and increased incidence of lower respiratory infections. This study looked at smoking trends among American Indian and white women in Minnesota who gave birth between 1999 and 2003. The authors used data from birth certificates issued by the state to determine the rate of smoking among both groups of women.

Ephrin-A5 inhibits growth of embryonic sensory neurons.

EphA-ephrin signaling has recently been implicated in the establishment of motor innervation patterns, in particular in determining whether motor axons project into dorsal versus ventral nerve trunks in the limb. We investigated whether sensory axons, which grow out together with and can be guided by motor axons, are also influenced by Eph-ephrin signaling. We show that multiple EphA receptors are expressed in DRGs when limb innervation is being established, and EphA receptors are present on growth cones of both NGF-dependent (predominantly cutaneous) and NT3-dependent (predominantly proprioceptive) afferents.

An early broad competence of motoneurons to express ER81 is later sculpted by the periphery.

The ETS transcription factor ER81 is expressed in sensory neurons and motoneurons that innervate the adductor and femorotibialis muscles in chick hindlimb and is essential for the development of monosynaptic connections between these two populations of neurons. Neurons need a signal(s) from limb bud mesoderm to initiate ER81 expression. It is not known whether the mature expression pattern arises because adductor and femorotibialis motoneurons are uniquely competent to respond to peripheral signals and express ER81, or whether all motoneurons are competent to express ER81, but normally only adductor and femorotibialis motoneurons are exposed to the requisite activating signal.

Development of "normal" dermatomes and somatotopic maps by "abnormal" populations of cutaneous neurons.

During development, motor and sensory axons grow to peripheral targets with remarkable precision. Whereas much has been learned about the development of motoneuron connectivity, less is known about the regulation of cutaneous innervation. In adults, dorsal root ganglia (DRG) innervate characteristic skin regions, termed dermatomes, and their axons project somatotopically in the dorsal horn.

In vivo analysis of Schwann cell programmed cell death in the embryonic chick: regulation by axons and glial growth factor.

The present study uses the embryonic chick to examine in vivo the mechanisms and regulation of Schwann cell programmed cell death (PCD) in spinal and cranial peripheral nerves. Schwann cells are highly dependent on the presence of axons for survival because the in ovo administration of NMDA, which excitotoxically eliminates motoneurons and their axons by necrosis, results in a significant increase in apoptotic Schwann cell death. Additionally, pharmacological and surgical manipulation of axon numbers also affects the relative amounts of Schwann cell PCD.
