A systematic review of smart clothing in sports: Possible applications to extreme sports
Background. Traditional monitoring of athletes during sports has long been hampered by bulky, complicated and tethered systems. In the past decade, this has changed due to the miniaturization of sensors and improvement of systems to store and transmit data. These systems have been integrated into textiles to create ‘smart clothing’ which has been so ubiquitous that a review of the recent literature is crucial for understanding its full potential and potential use in extreme sports.
Methods. An electronic data base search was performed from 2003 to April 2019 for full length articles including “Smart” AND “Clothing” OR “Clothing” AND “Sport(s)” written in English with human subjects. Articles were evaluated according to the Newcastle-Ottawa Scale.
Results. Twenty-four studies resulted in 18 systems comprised of 22 types of clothing with various capabilities, including: monitoring heart rate, electromyography, respiratory rate, steps, GPS, energy expenditure, posture, body temperature and identifying the activity.
Conclusions. Many types of smart clothing from socks and gloves, to pants, shirts and bras are increasingly utilized to monitor sports activity worldwide and gather previously unavailable, yet highly valuable data. This provides a unique opportunity to study athletes during training and competition, potentially providing more effective training and better safety protocols
Mapping the moral compass : the relationships between in-house lawyers' role, professional orientations, team cultures, organisational pressures, ethical infrastructure and ethical inclination
This is a survey of 400 in-house lawyers working in public, third and commercial sectors. We set out here the findings at the highest level. A number of organisations assisted with the distribution of the survey. This report provides a unique profile of real differences within the in-house community. We examine individual and team orientations to the in-house role; the invocation of professional principles; and ethical infrastructure, ethical pressure and relationships with the employer. We relate these to externally validated indicators of ethical inclination: (i) moral attentiveness (the extent to which people deal with problems as moral problems and the extent to which people identify moral problems); and (ii) moral disengagement (the extent to which people are inclined to morally disengage to behave unethically without feeling distress). It is as rich a picture of what it means to be an ethical inhouse lawyer as has ever been attempted. A more detailed summary and discussion of our findings is found in the final chapter of the main report for those who would like to know more but do not have the appetite or time to read the whole report. Through this research we profile the characteristics of individuals, teams and environments most associated with a stronger or weaker inclination to behave ethically. It is important to emphasise that this mapping of the 'moral compass' of in-house lawyers shows that ethicality is associated with individual and professional notions of the in-house role but also with team orientations and the broader organisational environment. Ethicality is both a systemic and individual phenomenon. We think the systemic lesson is important: there is too much emphasis in legal circles on thinking that ethics is about being the right sort of individual. That kind of thinking is complacent and dangerous. As we show here, individuals, systems and cultures mesh together in meaningful and measurable ways to increase or reduce ethical risk. As numerous corporate scandals have shown, such ethical risk puts individual lawyers at risk of professional misconduct but it also encourages poor quality decision-making for the organisations that employ in-house lawyers: short-termism and sharp practice can lead to catastrophic error
IMMUNOLOGIC REACTIONS TO HAPTENS ON AUTOLOGOUS CARRIERS : I. PARTICIPATION OF BOTH THYMUS-DERIVED AND BONE MARROW-DERIVED CELLS IN THE SECONDARY IN VITRO RESPONSE
Both thymus-derived (T) and bone marrow-derived (B) lymphocytes participate in the response to a hapten 4-hydroxy-3-iodo-5-nitrophenylacetic acid (NIP), coupled to a nonimmunogenic isologous carrier, mouse gamma globulin (MGG). Spleen cells from mice immunized with NIP-MGG show increased DNA synthesis in vitro when cultured with NIP-MGG. The participation of and requirement for T cells in the response was demonstrated by treating the spleen cells with anti-θ serum. This treatment resulted in a 77% inhibition of the antigen response. Furthermore, adoptively transferred normal thymus cells could be specifically "activated" by NIP-MGG in vivo and they responded secondarily to the antigen in vitro. The active participation of B cells in the secondary response was demonstrated by passing the immune spleen cells through a column coated with polyvalent anti-MGG serum. Column filtration reduced the number of NIP-specific plaque-forming cells and NIP-specific rosette-forming cells (both functions of B cells) and produced a 47% inhibition of the NIP-MGG response. The ability of the cells to respond to phytohemagglutinin (PHA) was not affected by column filtration showing that T cells were not being selectively removed. The participation of B cells in the in vitro NIP-MGG response was also shown by treatment of the spleen cells with antiserum specific for MGG and MGG determinants. B cells were removed by treatment with anti-IgM or polyvalent anti-MGG serum plus complement, resulting in a respective 46 and 49% inhibition of the response to NIP-MGG. (Treatment with anti-IgM serum had no effect on T cells.) The contribution of the hapten NIP to stimulation of T cells was investigated using NIP-MGG-activated thymus cells. These activated T cells responded in vitro very well to the NIP-MGG complex but not to the MGG carrier alone demonstrating the requirement of the hapten for T cell stimulation. The response was also partially inhibited (41%) by incubating the activated cells with NIP coupled to a single amino acid (epsilon-aminocaproic acid) before addition of NIP-MGG. These results demonstrated that T cells recognize the hapten NIP when it is coupled to the isologous carrier MGG
The ethical identity of law students
This is the author accepted manuscript. The final version is available from the publisher via the DOI in this recordThis paper uses measures of values, moral outlook and professional identity to explore the ethical and professional identity of law students. We do so in two jurisdictions, surveying 441 students studying in England and Wales and 569 students studying in the US. The survey covers the first and final years of an undergraduate law degree and the postgraduate vocational stage in England and Wales, as well as students in all years of the JD programme in the US. We explore whether law students towards the end of their legal education have ethical identities predictive of less ethical conduct than those at the beginning of their legal education; whether law students intending careers in business law have values and profiles consistent with less ethical conduct than those intending to work for government or individuals; and what factors might explain these differences in ethical outlook. Our findings suggest that ethical identity is strongly associated with gender and career intentions. They also suggest weaker moral identities for students intending to practise business law. Ultimately, our findings support a conclusion that is more nuanced than the predominant theses about the impact of legal education on student ethicality which tend to suggest legal education diminishes ethicality
Association between reductions in low-density lipoprotein cholesterol with statin therapy and the risk of new-onset diabetes: a meta-analysis
A recent meta-analysis demonstrated that statin therapy was associated with a risk of diabetes. The present study investigated whether the relative reduction in low-density lipoprotein cholesterol (LDL-c) was a good indicator of the risk of new-onset diabetes. We searched the PubMed, Embase, Cochrane Central Register, Lilacs, Food and Drug Administration, and European Medicines Agency databases for randomized controlled trials of statins. Fourteen trials were included in the study. Eight trials with target LDL-c levels ≤100 mg/dL (2.6 mmol/L) or LDL-c reductions of at least 30% were extracted separately. The results showed that the overall risk of incident diabetes increased by 11% (OR = 1.11; 95% CI 1.03–1.20). The group with intensive LDL-c-lowering statin had an 18% increase in the likelihood of developing diabetes (OR = 1.18; 95% CI, 1.10–1.28). Furthermore, the risks of incident diabetes were 13% (OR = 1.13; 95% CI 1.01–1.26) and 29% (OR = 1.29; 95% CI 1.13–1.47) in the subgroups with 30–40% and 40–50% reductions in LDL-c, respectively, suggesting that LDL-c reduction may provide a dynamic risk assessment parameter for new-onset diabetes. In conclusion, LDL-c reduction is positively related to the risk of new-onset diabetes. When LDL-c is reduced by more than 30% during lipid-lowering therapy, blood glucose monitoring is suggested to detect incident diabetes in high-risk populations

Decontamination of the hospital environment : new technologies for infection control
Environmental contamination is being increasingly recognized as a significant source of healthcare-associated infection (HAI). Cross-contamination of the patient from the environment can result from the direct transfer of organisms from the air and surfaces, or indirectly from the hospital environment via contact with healthcare workers or equipment. Traditional methods of environmental decontamination, including cleaning with disinfectants, and the standard infection control procedures implemented by modern Health Services, are critical to controlling the spread of potentially pathogenic microbial contaminants from environmental sources to the patient; however there is constant pressure to maintain, and indeed, improve on the standards that are in place to ensure optimal patient care. To address this issue, much research has been directed towards the development and testing of novel ‘whole-room’ environmental decontamination methods which could be used to enhance hospital hygiene, and consequently reduce the risk of HAI-acquisition from environmental sources. Gaseous methods such as the use of hydrogen peroxide, chlorine dioxide, ozone and steam, as well as ultraviolet and violet-blue visible light methods have all been laboratory tested, and to varying extents, clinically evaluated to assess their efficacy for environmental decontamination. This review article considers these different decontamination technologies, discussing their mechanism of action, antimicrobial efficacy, and advantages and limitations, with a view to providing the reader with a comprehensive overview of the technological advances being developed to reduce the levels of environmental contamination around patient areas, thus aiding in the fight against healthcare-associated infection
