This paper discusses an externally-funded project into Scottish coaches’ awareness of the sports concussion prevention initiative, If in Doubt, Sit Them Out. It explores the short-term risks of concussion to youth participants in particular before analysing the data from interviews with ten coaches of girls’ football. The coaches’ apparent lack of awareness of the policy are highlighted and the possibility that the different resources in girls’ and boys’ football, and between girls’ performance and girls’ recreational participation, might impact on injury recognition and treatment, are explored. The paper highlights the need for further research into those areas, and the need to immediately address the apparently low levels of awareness of If in Doubt. With that in mind, proposals for both immediate and longer-term reform for its dissemination are introduced.

Abstract Background Disease severity and outcome in community-acquired pneumonia (CAP) depend on the host and on the challenge of the causal microorganism(s). We measured levels of immunoglobulins (Igs) and complement in 257 hospitalized adults with CAP and examined the association of low levels of Igs or complement to microbial etiology, disease severity, and short-term and long-term outcome. Methods Serum Igs were analyzed in blood samples obtained at admission and at 6 weeks postdischarge if admission levels were low. Serum complement deficiencies were screened with a total complement activity enzyme-linked immunosorbent assay (ELISA), with further analyzes performed if justified. Disease severity was assessed by the CURB-65 severity score. Short-term outcome was defined as a composite end point of intensive care unit (ICU) admission and 30-day mortality, and long-term outcome as 5-year all-cause mortality. Results At admission, 87 (34%) patients had low levels of at least 1 Ig, with low IgG2 as the most prevalent finding (55/21%). IgG levels were lower in bacterial than viral CAP (8.48 vs 9.97 g/L, P = .023), but low Igs were not associated with microbial etiology. Fifty-five (21%) patients had low lectin pathway activity, of which 33 (13%) were mannose-binding lectin (MBL) deficient. Low admission levels of any Ig or MBL were not associated with disease severity, short-term outcome, or long-term outcome. Excluding patients defined as immunocompromised from analysis did not substantially affect these results. Conclusion In hospitalized adults with CAP, low admission levels of Igs or complement were in general not associated with microbial etiology, disease severity, short-term outcome, or long-term outcome.

AbstractThe development of tropical cloud clusters (TCCs) to tropical cyclones (TCs) is the process of TC formation. This study identifies five main environmental transitions for the development of TCCs to TCs in the western North Pacific by using a cluster analysis method. Of these, three transitions indicate TCCs that develop in monsoon environments and two in easterly environments. Their numbers, distributions, and interannual variability differ. On average, the development time, defined as the period from the TCC forming to it developing into a TC, for TCCs that develop in easterly environments is shorter than that in monsoon environments. For the development of TCC to TC in easterly environments, TCCs have fewer embedded mesoscale convective systems (MCSs), which are located closer to the TCC center. Moreover, there is a stronger inward short-term (less than 10 days) angular momentum flux (AMF) at middle levels (800–500 hPa) before TCC formation. Conversely, in monsoon environments, TCCs have more MCSs, which are located farther from the TCC center. A stronger inward short-term AMF at low levels (1000–850 hPa) is observed before TCC formation and develops upward during the development of TCC to TC. The characteristics of MCS and AMF are significantly correlated with the development time of TCC to TC. In summary, large-scale easterly and monsoon environments cause TCCs to have different MCS and AMF characteristics, leading to higher efficiency for TCCs developing into TCs in easterly environments compared to monsoon environments.

Subject The government's latest GDP expectations for 2016-19. Significance On September 19, days before surviving a parliamentary no-confidence vote, the government announced GDP projections for 2016-19, based on improvements in consumption growth and the labour market, where registered unemployment hovers at historically low levels. Despite its weakened position following the recent departure of junior coalition partner Siet, Smer-Social Democracy (SD) is upbeat about the prospects for robust GDP growth in 2016, revising its forecast upwards to 3.6% from 3.2%. Impacts Industrial output, GDP and inflationary pressures may pick up post-2018, as consumers spend more and auto industry investments create jobs. The government may miss its targets in the short term, but fiscal deficits should remain below the EU limit of 3% of GDP in 2016-18. More public-private partnerships, modelled on the Bratislava ring-road, plus EU funding, may support infrastructure investment after 2017.

Available Information

While many environmental disturbances have no readily detectable effect on aquatic invertebrates in the short term, they may prevent normal reproduction and cause eventual local extinction of a species. Small temperature changes may interfere with diapause signals and prevent completion of the life cycle. Heavy metals and toxic substances may drastically reduce reproduction rates in species exposed to sublethal levels. Dissolved salts and pH affect organisms at abnormally high or low levels but most mechanisms are unknown. It is concluded that relatively little information is available on the effects of environmental disturbances on life cycles. Available information, however, is sufficient to provide evidence of many problems that require attention. Key words: life histories, benthos, environmental disturbances, toxic substances, diapause, temperature, heavy metals

Lucerne plots were irrigated with waters of electrical conductivity (EC) = 0.1, 0.8, 2.5, 4.5 and 7.5 dS/m for the summers of 1991–92 to 1994–95. Within those 4 years, soils were sodified at irrigation treatment salinities greater than 0.8 dS/m. Subsequent leaching of salts with channel water (EC = 0.1 dS/m) and rain water (1995–97) reduced surface soil sodicity but not subsoil sodicity. This resulted in increased dispersed clay in the subsoil. Clay dispersion was best explained by exchangeable sodium percentage (ESP) and Mg in topsoils, and by ESP and salinity (TCC or Cl) in subsoils. Ponding of water, following a 46 mm spring rainfall event, increased with ESP of topsoils. Short-term millet yields over the 1996–97 summer were not affected by soil sodicity despite channel water irrigation. However, cumulative pasture yields over 1997 decreased by 25% between high and low levels of residual soil sodicity.

Mitochondria from the muscle-derived thermogenic (heater) organ and oxidative red muscle of the blue marlin (Makaira nigricans) were studied in order to evaluate aspects of the mechanism of thermogenesis in heater tissue. We investigated whether short-term Ca(2+)-induced uncoupling of mitochondria contributes to the thermogenic cycle of the heater organ by enhancing the respiration rate. Specific electrodes were used to obtain simultaneous measurements of oxygen consumption and Ca2+ fluxes on isolated mitochondria, and the effects of various concentrations of Ca2+ on respiration rates and the ADP phosphorylated/atomic oxygen consumed (P/O) ratio were examined. Addition of Ca2+ in excess of 10 mumol l-1 to respiring heater organ or red muscle mitochondria partially inhibited state 3 respiration and reduced the P/O ratio, indicating that the mitochondria were partially uncoupled. These effects were blocked by 2 mumol l-1 Ruthenium Red. In heater organ mitochondria, state 3 respiration rate and the P/O ratio were not significantly reduced by 1 mumol l-1 free Ca2+, a concentration likely to be near the maximum achieved in a stimulated cell. This indicates that transient increases in cytosolic Ca2+ concentration may not significantly reduce the P/O ratio of heater organ mitochondria. The activity of 2-oxoglutarate dehydrogenase in heater organ mitochondria was stimulated by approximately 15% by Ca2+ concentrations between 0.2 and 1 mumol l-1. These results suggest that heater organ mitochondria are able to maintain a normal P/O ratio and should maintain ATP output during transient increases in Ca2+ concentration, supporting a model in which an ATP-consuming process drives thermogenesis. Activation of mitochondrial dehydrogenases by low levels of Ca2+ may also enhance respiration and contribute to thermogenesis.

Apparent Lack

Scientific data are as important as scientific publications. If this statement holds true, why are we not routinely sharing scientific data? The tools are now out there, for instance Zenodo and related repositories. It could be a lack of motivation of researchers derived from an apparent lack of short-term reward. Here the author will try to show the importance of sharing ready-to-analyse raw powder diffraction data with immediate benefits for authors and for the wider community. Moreover, it is speculated that sharing curated scientific data may have more important medium-term benefits, including credibility and not least reproducibility. Raw data sharing is coming.
