Abstract Tesim:
Shallow lakes, particularly those in low-lying areas of the subtropics, are highly vulnerable to changes in climate associated with global warming. Many of these lakes are in tropical cyclone strike zones and they experience high inter-seasonal and inter-annual variation in rainfall and runoff. Both of those factors strongly modulate sediment–water column interactions, which play a critical role in shallow lake nutrient cycling, water column irradiance characteristics and cyanobacterial harmful algal bloom (CyanoHAB) dynamics. We illustrate this with three examples, using long-term (15–25 years) datasets on water quality and plankton from three shallow lakes: Lakes Okeechobee and George (Florida, USA) and Lake Taihu (China). Okeechobee and Taihu have been impacted repeatedly by tropical cyclones that have resulted in large amounts of runoff and sediment resuspension, and resultant increases in dissolved nutrients in the water column. In both cases, when turbidity declined, major blooms of the toxic CyanoHAB Microcystis aeruginosa occurred over large areas of the lakes. In Lake George, periods of high rainfall resulted in high dissolved color, reduced irradiance, and increased water turnover rates which suppress blooms, whereas in dry periods with lower water color and water turnover rates there were dense cyanobacteria blooms. We identify a suite of factors which, from our experience, will determine how a particular shallow lake will respond to a future with global warming, flashier rainfall, prolonged droughts and stronger tropical cyclones.

Abstract Tesim:
<p>Symptoms adolescents experience during their first time using a cigarette predict their current use, but little is known regarding the symptoms experienced during first e-cigarette use. We conducted a pilot study to understand the symptoms adolescents experience when they first tried cigarettes and e-cigarettes and the associations between these symptoms and current use. Participants were 41 adolescents in two U.S. cities who had tried cigarettes or e-cigarettes. We asked adolescents to recall the symptoms they experienced during their first cigarette or e-cigarette and categorized symptoms as negative (felt bad, coughing/chest pain, bad taste, upset stomach, dizzy/lightheaded) or positive (felt relaxed, rush/buzz). Adolescents reported fewer negative symptoms for first e-cigarette than first cigarette use (all p &lt; 0.05). Current cigarette smoking was associated with endorsing fewer negative symptoms (OR = 0.49, 95% CI = [0.25, 0.95]) and more positive symptoms (OR = 7.11, 95% CI = [1.47, 34.33]) at first cigarette use. First e-cigarette use symptoms were not associated with current e-cigarette use. Adolescents reported fewer negative symptoms from first e-cigarette than from first cigarette, and e-cigarette symptoms did not influence use as they do for cigarettes. Additional research is needed to confirm these findings in longitudinal studies.</p>

1063. Working with Climate Projections to Estimate Disease Burden: Perspectives from Public Health

Title Tesim:
Working with Climate Projections to Estimate Disease Burden: Perspectives from Public Health
Creator:
Uejio, Christopher K., Stefanova, Lydia, Conlon, Kathryn C., Konrad, Charles, Kintziger, Kristina W., and Jagger, Meredith
Date of publication:
2016
Abstract Tesim:
There is interest among agencies and public health practitioners in the United States (USA) to estimate the future burden of climate-related health outcomes. Calculating disease burden projections can be especially daunting, given the complexities of climate modeling and the multiple pathways by which climate influences public health. Interdisciplinary coordination between public health practitioners and climate scientists is necessary for scientifically derived estimates. We describe a unique partnership of state and regional climate scientists and public health practitioners assembled by the Florida Building Resilience Against Climate Effects (BRACE) program. We provide a background on climate modeling and projections that has been developed specifically for public health practitioners, describe methodologies for combining climate and health data to project disease burden, and demonstrate three examples of this process used in Florida.

1064. Social Interactions as a Source of Information about E-Cigarettes: A Study of U.S. Adult Smokers

Title Tesim:
Social Interactions as a Source of Information about E-Cigarettes: A Study of U.S. Adult Smokers
Creator:
Pepper, Jessica K., Brewer, Noel T., Morgan, Jennifer C., and Hall, Marissa G.
Date of publication:
2016
Abstract Tesim:
<p>The novelty of e-cigarettes and ambiguity about their effects may foster informal sharing of information, such as through social interactions. We aimed to describe smokers&rsquo; social interactions about e-cigarettes and their recommendations that others use e-cigarettes. Data were collected from 2149 adult smokers in North Carolina and California who participated in a study of the impact of pictorial cigarette pack warnings. In the previous month, almost half of participants (45%) reported talking to at least one person about e-cigarettes and nearly a third of participants (27%) recommended e-cigarettes to someone else. Smokers recommended e-cigarettes to cut back on smoking (57%), to quit smoking (48%), for health reasons (36%), and for fun (27%). In adjusted analyses, more frequent e-cigarette use, positive views about typical e-cigarette users, and attempting to quit smoking in the past month were associated with recommending e-cigarettes for health reasons (all p &lt; 0.05). Social interactions appear to be a popular method of information-sharing about e-cigarettes among smokers. Health communication campaigns may help to fill in the gaps of smokers&rsquo; understanding of e-cigarettes and their long-term effects.</p>

1065. A Comprehensive Evaluation of the Burden of Heat-Related Illness and Death within the Florida Population

Title Tesim:
A Comprehensive Evaluation of the Burden of Heat-Related Illness and Death within the Florida Population
Creator:
Kintziger, Kristina, Morano, Laurel Harduar, and Watkins, Sharon
Date of publication:
2016
Abstract Tesim:
The failure of the human body to thermoregulate can lead to severe outcomes (e.g., death) and lasting physiological damage. However, heat-related illness (HRI) is highly preventable via individual- and community-level modification. A thorough understanding of the burden is necessary for effective intervention. This paper describes the burden of severe HRI morbidity and mortality among residents of a humid subtropical climate. Work-related and non-work-related HRI emergency department (ED) visits, hospitalizations, and deaths among Florida residents during May to October (2005–2012) were examined. Sub-groups susceptible to HRI were identified. The age-adjusted rates/100,000 person-years for non-work-related HRI were 33.1 ED visits, 5.9 hospitalizations, and 0.2 deaths, while for work-related HRI/100,000 worker-years there were 8.5 ED visits, 1.1 hospitalizations, and 0.1 deaths. The rates of HRI varied by county, data source, and work-related status, with the highest rates observed in the panhandle and south central Florida. The sub-groups with the highest relative rates regardless of data source or work-relatedness were males, minorities, and rural residents. Those aged 15–35 years had the highest ED visit rates, while for non-work-related hospitalizations and deaths the rates increased with age. The results of this study can be used for targeted interventions and evaluating changes in the HRI burden over time.

1066. Establishing Pine Monocultures and Mixed Pine-Hardwood Stands on Reclaimed Surface Mined Land in Eastern Kentucky: Implications for Forest Resilience in a Changing Climate

Title Tesim:
Establishing Pine Monocultures and Mixed Pine-Hardwood Stands on Reclaimed Surface Mined Land in Eastern Kentucky: Implications for Forest Resilience in a Changing Climate
Creator:
French, Michael, Bell, Geoffrey, Barton, Christopher D., and Sena, Kenton L.
Date of publication:

Abstract Tesim:
Surface mining and mine reclamation practices have caused significant forest loss and forest fragmentation in Appalachia. Shortleaf pine (Pinus echinata) is threatened by a variety of stresses, including diseases, pests, poor management, altered fire regimes, and climate change, and the species is the subject of a widescale restoration effort. Surface mines may present opportunity for shortleaf pine restoration; however, the survival and growth of shortleaf pine on these harsh sites has not been critically evaluated. This paper presents first-year survival and growth of native shortleaf pine planted on a reclaimed surface mine, compared to non-native loblolly pine (Pinus taeda), which has been highly successful in previous mined land reclamation plantings. Pine monoculture plots are also compared to pine-hardwood polyculture plots to evaluate effects of planting mix on tree growth and survival, as well as soil health. Initial survival of shortleaf pine is low (42%), but height growth is similar to that of loblolly pine. No differences in survival or growth were observed between monoculture and polyculture treatments. Additional surveys in coming years will address longer-term growth and survival patterns of these species, as well as changes to relevant soil health endpoints, such as soil carbon.
