What to do about children\u27s persistent challenging behaviors? TEACH!

This will be an extended session to allow parents and teachers to conduct a preliminary assessment of one child\u27s behavior and develop an initial behavior intervention plan. We will use the Brief Behavior Questionnaire and Intervention Plan (BBQuIP) to guide our efforts. The Brief Behavior Questionnaire & Intervention Plan (BBQuIP) is a positive behavior support planning tool. The focus of the session will be to identify the communicative function of one child\u27s persistent behaviors, select ways to prevent the behavior, and select one or more replacement skills to be taught. This is a lot to accomplish in a short time, so come to this session ready to work

Inflammation and Infection Do Not Promote Arterial Aging and Cardiovascular Disease Risk Factors Among Lean Horticulturalists

Background: Arterial aging is well characterized in industrial populations, but scantly described in populations with little access to modern medicine. Here we characterize health and aging among the Tsimane, Amazonian forager-horticulturalists with short life expectancy, high infectious loads and inflammation, but low adiposity and robust physical fitness. Inflammation has been implicated in all stages of arterial aging, atherogenesis and hypertension, and so we test whether greater inflammation associates with atherosclerosis and CVD risk. In contrast, moderate to vigorous daily activity, minimal obesity, and low fat intake predict minimal CVD risk among older Tsimane. Methods and Findings: Peripheral arterial disease (PAD), based on the Ankle-Brachial Index (ABI), and hypertension were measured in Tsimane adults, and compared with rates from industrialized populations. No cases of PAD were found among Tsimane and hypertension was comparatively low (prevalence: 3.5%, 40+; 23%, 70+). Markers of infection and inflammation were much higher among Tsimane than among U.S. adults, whereas HDL was substantially lower. Regression models examine associations of ABI and BP with biomarkers of energy balance and metabolism and of inflammation and infection. Among Tsimane, obesity, blood lipids, and disease history were not significantly associated with ABI. Unlike the Tsimane case, higher cholesterol, C-reactive protein, leukocytes, cigarette smoking and systolic pressure among North Americans are all significantly associated with lower ABI. Conclusions: Inflammation may not always be a risk factor for arterial degeneration and CVD, but instead may be offset by other factors: healthy metabolism, active lifestyle, favorable body mass, lean diet, low blood lipids and cardiorespiratory health. Other possibilities, including genetic susceptibility and the role of helminth infections, are discussed. The absence of PAD and CVD among Tsimane parallels anecdotal reports from other small-scale subsistence populations and suggests that chronic vascular disease had little impact on adult mortality throughout most of human evolutionary history

Distinct TLR- and NLR-Mediated Transcriptional Responses to an Intracellular Pathogen

How the innate immune system tailors specific responses to diverse microbial infections is not well understood. Cells use a limited number of host receptors and signaling pathways to both discriminate among extracellular and intracellular microbes, and also to generate responses commensurate to each threat. Here, we have addressed these questions by using DNA microarrays to monitor the macrophage transcriptional response to the intracellular bacterial pathogen Listeria monocytogenes. By utilizing combinations of host and bacterial mutants, we have defined the host transcriptional responses to vacuolar and cytosolic bacteria. These compartment-specific host responses induced significantly different sets of target genes, despite activating similar transcription factors. Vacuolar signaling was entirely MyD88-dependent, and induced the transcription of pro-inflammatory cytokines. The IRF3-dependent cytosolic response induced a distinct set of target genes, including IFNβ. Many of these cytosolic response genes were induced by secreted cytokines, so we further identified those host genes induced independent of secondary signaling. The host response to cytosolic bacteria was reconstituted by the cytosolic delivery of L. monocytogenes genomic DNA, but we observed an amplification of this response by NOD2 signaling in response to MDP. Correspondingly, the induction of IFNβ was reduced in nod2−/− macrophages during infection with either L. monocytogenes or Mycobacterium tuberculosis. Combinatorial control of IFNβ induction by recognition of both DNA and MDP may highlight a mechanism by which the innate immune system integrates the responses to multiple ligands presented in the cytosol by intracellular pathogens

Experiential Learning Through Participatory Action Research in an Interdisciplinary Leadership Training Program

Background: Experience in multidisciplinary collaboration among healthcare providers, leaders in public health, and educators is essential to effectively address the diverse needs of children with intellectual and developmental disabilities (I/DD) and their families. Purpose: We describe three participatory action research (PAR) projects from an interdisciplinary training program, which used experiential learning to enhance leadership competencies and promote inclusive services. Trainees report their leadership growth as providers and advocates for children with I/DD using experiential learning through PAR. Approach: Trainees discuss their engagement with organizations serving children with I/DD and ways that experiential learning supported leadership skill development, commitment to inclusive person- and family-centered practices, and contributions to disability advocacy and support programs. Conclusion: PAR is a beneficial experiential learning approach to foster interdisciplinary collaboration through inclusive community engagement. Related training programs may adopt a similar approach to build leadership skills among professionals in health care, public health, and education, and promote optimal health outcomes for children with I/DD

The Missing Piece: Drought Impacts Monitoring Report from a Workshop in Tucson, AZ MARCH 5-6, 2013

Based on a shared interest to better understand the impacts of drought and the potential utility of using drought impacts reporting as a tool for monitoring conditions, researchers from the Carolinas RISA (Dow, Lackstrom, and Brennan), the Climate Assessment for the Southwest (Crimmins and Ferguson), and the Southwest Climate Science Center (Meadow) decided to convene a workshop in Tucson in March 2013. The primary goal was to assemble a small group of university and agency scientists involved with drought impacts monitoring to discuss opportunities and barriers associated with drought impacts reporting, recommend best practices for implementing a drought impacts reporting system, and develop a path forward for addressing or overcoming barriers. The longer-term objective of the initial meeting was to explore the feasibility of creating a community of practice that could share information and integrate activities related to drought impacts research and reporting

(R)-2-Phen­oxy-1-(4-phenyl-2-sulfan­ylidene-1,3-oxazolidin-3-yl)ethanone

The central 1,3-oxazolidine-2-thione ring in the title compound, C17H15NO3S, is approximately planar with maximum deviations of 0.036 (4) and −0.041 (5) Å for the O and methyl­ene-C atoms, respectively. The dihedral angles formed between this plane and the two benzene rings, which lie to the same side of the central plane, are 86.5 (2) [ring-bound benzene] and 50.6 (3)°. The ethan-1-one residue is also twisted out of the central plane, forming a O—C—N—C torsion angle of 151.5 (5)°. The dihedral angle formed by the benzene rings is 62.8 (2)° so that overall, the mol­ecule has a twisted U-shape. In the crystal, mol­ecules are linked into supra­molecular arrays two mol­ecules thick in the bc plane through C—H⋯O, C—H⋯S and C—H⋯π inter­actions

Temperature-related changes in airborne allergenic pollen abundance and seasonality across the northern hemisphere : a retrospective data analysis

BACKGROUND: Ongoing climate change might, through rising temperatures, alter allergenic pollen biology across the northern hemisphere. We aimed to analyse trends in pollen seasonality and pollen load and to establish whether there are specific climate-related links to any observed changes. METHODS: For this retrospective data analysis, we did an extensive search for global datasets with 20 years or more of airborne pollen data that consistently recorded pollen season indices (eg, duration and intensity). 17 locations across three continents with long-term (approximately 26 years on average) quantitative records of seasonal concentrations of multiple pollen (aeroallergen) taxa met the selection criteria. These datasets were analysed in the context of recent annual changes in maximum temperature (T) and minimum temperature (T) associated with anthropogenic climate change. Seasonal regressions (slopes) of variation in pollen load and pollen season duration over time were compared to T, cumulative degree day T, T, cumulative degree day T, and frost-free days among all 17 locations to ascertain significant correlations. FINDINGS: 12 (71%) of the 17 locations showed significant increases in seasonal cumulative pollen or annual pollen load. Similarly, 11 (65%) of the 17 locations showed a significant increase in pollen season duration over time, increasing, on average, 0·9 days per year. Across the northern hemisphere locations analysed, annual cumulative increases in T over time were significantly associated with percentage increases in seasonal pollen load (r=0·52, p=0·034) as were annual cumulative increases in T (r=0·61, p=0·010). Similar results were observed for pollen season duration, but only for cumulative degree days (higher than the freezing point [0°C or 32°F]) for T (r=0·53, p=0·030) and T (r=0·48, p=0·05). Additionally, temporal increases in frost-free days per year were significantly correlated with increases in both pollen load (r=0·62, p=0·008) and pollen season duration (r=0·68, p=0·003) when averaged for all 17 locations. INTERPRETATION: Our findings reveal that the ongoing increase in temperature extremes (T and T) might already be contributing to extended seasonal duration and increased pollen load for multiple aeroallergenic pollen taxa in diverse locations across the northern hemisphere. This study, done across multiple continents, highlights an important link between ongoing global warming and public health-one that could be exacerbated as temperatures continue to increase.
