Fit for Life: Educating About a Healthy Lifestyle in Omaha Elementary Schools
Background: The prevalence of childhood obesity is increasing across the country. Health education at a young age is critical for children to establish healthy habits. The Fit for Life program is put together by Creighton medical students to inspire elementary students to lead a healthy lifestyle. The curriculum integrates physical exercise, real organ demonstrations, emotional wellness exercises, and nutritious meal building to model and encourage healthy habits.
Methods: Over four weeks, medical students taught the 4th and 5th graders of two Omaha schools over live video while they followed along with hands-on activities. Before and after the program, students’ height and weight were measured to calculate BMI, and the students completed pre- and post-program quizzes. Paired t-tests were performed to analyze differences in student BMIs and quiz scores. Pre-program quiz scores of students who completed two consecutive years were compared using paired t-tests.
Results: Student BMIs before and after the program showed no significant changes (p = 0.479, n = 45) however, quiz scores significantly improved after the program (p \u3c 0.001, n = 44). Self-reported survey responses after the program demonstrate increased motivation for a healthy lifestyle as well as improved understanding of the importance of sleep, exercise, reduced screen time, and healthy eating. Those who completed the program for two consecutive years had significantly higher pre-program quiz scores the second year (p \u3c 0.05, n = 18).
Conclusion: Our study found a significant increase in pre- and post-program assessment scores which suggest improvement in student perspective and knowledge of healthy habits. Similarly, students who completed the program for two consecutive years demonstrated an increase in pre-program quiz scores suggesting retention of health knowledge. While there was no significant difference in pre- and post-program BMIs, results may be limited by the duration of the study, given that changes in weight are often insubstantial in the short-term.https://digitalcommons.unmc.edu/chri_forum/1006/thumbnail.jp
LSST Science Book, Version 2.0
A survey that can cover the sky in optical bands over wide fields to faint
magnitudes with a fast cadence will enable many of the exciting science
opportunities of the next decade. The Large Synoptic Survey Telescope (LSST)
will have an effective aperture of 6.7 meters and an imaging camera with field
of view of 9.6 deg^2, and will be devoted to a ten-year imaging survey over
20,000 deg^2 south of +15 deg. Each pointing will be imaged 2000 times with
fifteen second exposures in six broad bands from 0.35 to 1.1 microns, to a
total point-source depth of r~27.5. The LSST Science Book describes the basic
parameters of the LSST hardware, software, and observing plans. The book
discusses educational and outreach opportunities, then goes on to describe a
broad range of science that LSST will revolutionize: mapping the inner and
outer Solar System, stellar populations in the Milky Way and nearby galaxies,
the structure of the Milky Way disk and halo and other objects in the Local
Volume, transient and variable objects both at low and high redshift, and the
properties of normal and active galaxies at low and high redshift. It then
turns to far-field cosmological topics, exploring properties of supernovae to
z~1, strong and weak lensing, the large-scale distribution of galaxies and
baryon oscillations, and how these different probes may be combined to
constrain cosmological models and the physics of dark energy.Comment: 596 pages. Also available at full resolution at

LSST: from Science Drivers to Reference Design and Anticipated Data Products
(Abridged) We describe here the most ambitious survey currently planned in
the optical, the Large Synoptic Survey Telescope (LSST). A vast array of
science will be enabled by a single wide-deep-fast sky survey, and LSST will
have unique survey capability in the faint time domain. The LSST design is
driven by four main science themes: probing dark energy and dark matter, taking
an inventory of the Solar System, exploring the transient optical sky, and
mapping the Milky Way. LSST will be a wide-field ground-based system sited at
Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m
effective) primary mirror, a 9.6 deg field of view, and a 3.2 Gigapixel
camera. The standard observing sequence will consist of pairs of 15-second
exposures in a given field, with two such visits in each pointing in a given
night. With these repeats, the LSST system is capable of imaging about 10,000
square degrees of sky in a single filter in three nights. The typical 5
point-source depth in a single visit in will be (AB). The
project is in the construction phase and will begin regular survey operations
by 2022. The survey area will be contained within 30,000 deg with
, and will be imaged multiple times in six bands, ,
covering the wavelength range 320--1050 nm. About 90\% of the observing time
will be devoted to a deep-wide-fast survey mode which will uniformly observe a
18,000 deg region about 800 times (summed over all six bands) during the
anticipated 10 years of operations, and yield a coadded map to . The
remaining 10\% of the observing time will be allocated to projects such as a
Very Deep and Fast time domain survey. The goal is to make LSST data products,
including a relational database of about 32 trillion observations of 40 billion
objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures

The Frequency and Outcome of Ph-like ALL Associated Abnormalities in Childhood Acute Lymphoblastic Leukaemia Treated on MRC UKALL2003
Outcomes of Prediabetes Compared with Normoglycaemia and Diabetes Mellitus in Patients Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-analysis.
: Patients with prediabetes are at increased risk of coronary artery disease (CAD). However, the association between prediabetes and adverse clinical outcomes following percutaneous coronary intervention (PCI) is inconsistent, in contrast to outcomes in patients with diabetes mellitus (DM). Thus, this meta-analysis evaluated the impact of dysglycaemia on PCI outcomes. : The PubMed, Embase, Cochrane, and ClinicalTrials.gov databases were systematically reviewed from inception of databases until June 2022. In 17 studies, outcomes of PCI in patients with prediabetes were compared with patients who were normoglycaemic, and patients with DM. The primary outcome was all-cause mortality at the longest follow-up. : Included were 12 prospective and five retrospective studies, with 11,868, 14,894 and 13,536 patients undergoing PCI in the prediabetes, normoglycaemic and DM groups, respectively. Normoglycaemic patients had a statistically lower risk of all-cause mortality, (risk ratio [RR] 0.66, 95% confidence interval [CI] 0.52-0.84), myocardial infarction (MI; RR 0.76, 95% CI 0.61-0.95) and cardiac mortality (RR 0.58, 95% CI 0.39-0.87) compared with prediabetic patients undergoing PCI at the longest follow-up. Patients with prediabetes had a lower risk of all-cause mortality (RR=0.72 [95% CI 0.53-0.97]) and cardiac mortality (RR =0.47 [95% CI 0.23-0.93]) compared with patients with DM who underwent PCI. : Among patients who underwent PCI for CAD, the risk of all-cause and cardiac mortality, major adverse cardiovascular events and MI in prediabetic patients was higher compared with normoglycaemic patients but lower compared with patients with DM.

How to analyze time and change in qualitative longitudinal materials? : Insights from a literature review of longitudinal qualitative studies in nursing.
Background Longitudinal qualitative research can give new insights in social processes and experiences over time. In recent years, there has been a growing interest in conducting longitudinal qualitative research within nursing. However, the definition of what constitutes longitudinal qualitative research is unclear, the methodological literature scarce, and the variation of procedures great. This review of longitudinal qualitative articles within the nursing field aims to identify and describe various types of qualitative longitudinal approaches. Materials and Method Searches in pubmed identified over a hundred qualitative nursing articles with data collection over time. These articles were analyzed regarding 1) described analysis procedure, 2) how the results related to aspects of time and change, and 3) if results were person oriented vs category oriented. Results Five different types of longitudinal qualitative approaches were identified. In total, a large part of the papers described as having a longitudinal design performed a data collection over time, but did not integrate ideas of time or change in their analysis or results. Four fruitful approaches to analyzing longitudinal qualitative data were identified; time-line, pool, phase and pattern-oriented approaches. Articles classified as using any of these approaches have a clear perspective of time or change in the results. However, depending on type of approach different aspects of time, change, and process are in focus. Further, using different approaches yielded different kinds of results. Conclusion All approaches have pros and cons and researchers need to make informed decisions when choosing which approach they will take when analyzing qualitative longitudinal material
