V.OBJECTIVES To explore what actually happens in relation to physical activity promotion in primary and junior schools within one unitary authority and to relate this to Public Health England (PHE) promising principles of practice to promote physical activity in schools. STUDY DESIGN A qualitative approach was undertaken to explore practice in all primary and junior schools in the unitary authority of Southampton. METHODS All primary (n = 36) and junior (n = 8) schools in Southampton were involved in the study. Publicly available primary physical education and sport premium (PESP) funding reports (n = 36) alongside a school survey (n = 14) were collated. The collated qualitative data set was semantically coded and then a multilayered approach including identification, reviewing, defining and naming meaningful and important themes were inductively developed. The inductively developed themes were then fitted in relation to PHE eight promising principles. RESULTS There was evidence of practice across all eight prold be considered. The two key themes that need to be addressed for the ambitions established in the new school sport and activity action plan to be deliverable, with PESP funding as a driver, are skilled workforce and development of a wider understanding of what physical activity is. OBJECTIVES A constant challenge in addressing the issue of obesity is the validity and reliability of self-reported measurements to calculate body mass index, that assesses the prevalence of obesity in a population. The objective of this study is to analyze both awareness and accuracy of mothers who are overweight or obese, in reporting their own and their child's height and weight measurements. STUDY DESIGN cross-sectional study. METHODS In this study, mothers were asked over phone to self-report height and weight for them and their child. This was followed by objective measurement of maternal and child height and weight by study staff in a clinical setting. The descriptive and statistical analysis of the data obtained were carried out using SAS software. RESULTS 1) The mean weight of mothers who inaccurately self-reported their weight was 9.5 kg greater than the mean weight of those who reported accurately (P  less then  0.001). (2) Despite being aware of, and reporting their own measurements, 50% (n = 116) of mothers reported not knowing their child's height and 23% (n = 54) of them reported not knowing their child's weight. CONCLUSION Strategies to tackle both maternal awareness and accuracy of child's measurements can help with early identification of child's obesity risk and prevention of long-term consequences. Perfluorooctane sulfonate (PFOS) has been widely used as a surface coating for household products. It still exists in living environments despite being restricted, due to its bioaccumulation and long half-life. Studies have shown that PFOS has the ability to induce adipogenic differentiation of human cells. Human mesenchymal stem cells (hMSCs) distributed within the adipose tissue might be a potential target of accumulated PFOS. However, traditional end-point toxicity assays failed to examine the subtle changes of cellular function exposed to low-dose persistent organic pollutants in real time. In the present work, highly sensitive and long-retained (more than 30 days) fluorescence based polymeric nanosensors were developed and employed for real-time assessment of cellular functions. hMSCs were engineered with sensor molecules encapsulated poly (lactic-co-glycolic acid) (PLGA) particles. Once internalized by hMSCs, PLGA particles continuously release and replenish sensor molecules to cytoplasm, resulting in prolonged fluorescence signal against photo bleaching and dilution by exocytosis. With this method, the dynamic changes of viability, ROS induction, and adipogenic differentiation related mRNA expression of hMSCs were monitored. PFOS with the concentration as low as 0.1 μM can induce cellular ROS and enhance the PPARγ and ap2 mRNA expression, suggesting the effect on promoting adipogenic differentiation of hMSCs. Silver nanoparticles (AgNPs) are expected to enter aquatic systems, but there are limited data on how they might affect microbial communities in pathogen impaired streams. We examined microbial community responses to citrate-AgNP (10.9 ± 0.7 nm) and polyvinylpyrrolidone (PVP)-AgNP (11.0 ± 0.7 nm) based on microbial concentration and enzyme activity in sediment from a pathogen impaired stream. Addition of each nanoparticle to sediment caused at least a 69% decrease in microbial concentration (1,264 ± 93.6 to 127 ± 29.5 CFU/g) and a 62% decrease in β-glucosidase activity (11.7 ± 2.1 to 1.3 ± 0.3 μg/g/h). Each AgNP reduced alkaline phosphatase activity but their effects were not statistically significant. Sediment exposed to 0.108 mg Ag/kg of AgNO3 resulted in a 92% decrease in microbial concentration and a reduced enzyme activity which was not statistically significant. Measured total silver in sediments treated with AgNPs which exhibited significant inhibition effects on the microbial community ranged from 0.19 ± 0.02 to 0.39 ± 0.13 mg Ag/kg. These concentrations tested in this study are much lower than the expected concentrations (2-14 mg Ag/kg) in freshwater sediments. The results of this study demonstrate that AgNPs can alter microbial community activity and population size, which may lead to false negative fecal indicator bacteria detection and enumeration using methods that rely on β-glucosidase activity. We conclude that the presence of AgNPs in impaired streams and recreational waters can influence pathogen detection methods, potentially affecting public health risk estimates. Increasing levels of road noise are creating new anthropogenic soundscapes that may affect wildlife globally. Bats, which form about a third of all mammal species, are sensitive bioindicators, and may be particularly vulnerable because of their dependency on echolocation. Here we present the first controlled field experiment with free-living bats. Using a Before-After-Control-Impact phantom road experimental design, we examine the impacts of traffic noise on their activity and feeding behaviour. Disentangling the impacts of traffic noise from other co-varying exposures such as habitat quality, the experiment demonstrates a significant negative effect on the activity of each of the five, ecologically different, species (genus for Myotis spp.) examined. This suggests that the results are widely applicable. The negative effects are largely attributable to noise in the sonic spectrum, which elicited aversive responses in all bat species tested,whereas responses to ultrasoundwere restricted to a single species. Our findings demonstrate that traffic noise can affect bat activity at least 20m away from the noise source. For Pipistrellus pipistrellus and Pipistrellus pygmaeus, feeding behaviour, as well as overall activity, was negatively affected. Ecological Impact Assessments are therfore needed wherever there are significant increases in traffic flow, and not just when new roads are built. Further research is required to identify effective mitigation strategies, to delineate the zone of influence of road noise, and to assess whether there is any habituation over time. BACKGROUND Most prior studies adopted a static residence-based approach in the assessment of noise exposure, which may lead to biased exposure estimates and misleading findings in noise-health relationships. Relatively little is known about personal noise exposure based on individuals' space-time behavior and its effect on mental health. OBJECTIVES This study aims to analyze and geo-visualize personal exposure to noise in various microenvironments based on individuals' space-time trajectories at a very fine resolution and to further investigate the relationships between mental health and personal noise exposure at both the activity/travel episode level and the entire day level. METHODS Individual-level real-time data were collected with portable noise sensors and GPS trackers from a sample of 117 residents aged 18-60 years old from December 2017 to February 2018 in Beijing, China. Descriptive statistics and geo-visualization methods were used to examine how personal noise exposure varied across different actirongly depend on different space-time behaviors and individual-specific microenvironments experienced in daily life, and they were significantly correlated with mental health. In order to investigate pollution level, chemical speciation and health risk of exposure to heavy metals in street dust from smelting district, we carried the following studies (a). the differences in the morphology of street dust in smelting and non-smelting districts using a scanning electron microscope; (b). the chemical speciation and bioavailability of heavy metals in  Pb (5.08%), respectively. Hand-to-mouth ingestion poses the greatest non-carcinogenic exposure risk compared with other exposure pathways. When bioavailability is taken into account, children experienced higher non-carcinogenic and carcinogenic risks of dust exposure compared with adults, and the less then 63 μm particles posed greater risks than less then 100 μm particles. The complexity and the mechanistic role of microbial communities at mucosal surfaces are only now beginning to be understood. Their impact on host metabolism, development, and immune responses to infectious and inert stimuli may be centrally linked to the metabolic functions of these communities within the established microbiome. The structure and function of microbial communities are influenced both early and throughout life by many environmental factors, exposures, diet, and disease. Understanding how the microbiome influences the host during health is likely just as important as understanding how it influences asthmatic disease predisposition and severity. BACKGROUND Crowdfunding has become a unique response to the challenge of health care expenses, yet it has been rarely studied by the medical community. We looked to describe the scope of crowdfunding in thyroid surgery and analyze the factors that contribute toward a successful campaign. METHODS In November 2018, active campaigns were retrieved from a popular crowdfunding Web site using search terms thyroidectomy and thyroid surgery and filtered to include only campaigns that originated in the United States. RESULTS About 1052 thyroid surgery-related campaigns were analyzed. About 836 (79.5%) involved female patients and 43 (4.1%) pediatric patients. About 792 campaigns (75.3%) referred to thyroid cancer as a primary condition, 163 (15.5%) benign thyroid disease, and 97 (9.2%) other conditions. The average amount raised per campaign was $2514.54 (range, $0-$53,160). About 338 (32.1%) campaigns were self-posted, 317 (30.1%) posted by family, and 397 (37.7%) posted by friends. Median campaign duration was 20 mo, with a median number of 16 donors, 17 hearts, and 136 social media shares. Campaigns related to thyroid cancer raised more funds ($2729.97) than benign ($1669.84) or other ($2175.03) conditions (P  less then  0.001). Campaigns submitted by friends ($3524.78) received more funding than those by self ($1672.48) or family ($2147.19) (P  less then  0.001). Campaign duration, donor number, share number, and hearts were also significant predictors of amount raised. CONCLUSIONS For thyroid surgery-related crowdfunding, campaigns referring to thyroid cancer had the highest amount of funds raised. MRTX1719 nmr Campaigns created by friends and other factors related to increased community engagement such as social media shares were also related to increased funds.
