Summary

Although network analysis has drawn considerable attention as a promising tool for disease ecology, empirical research has been hindered by limitations in detecting the occurrence of pathogen transmission (who transmitted to whom) within social networks.

Using a novel approach, we utilize the genetics of a diverse microbe, Escherichia coli, to infer where direct or indirect transmission has occurred and use these data to construct transmission networks for a wild giraffe population (Giraffe camelopardalis). Individuals were considered to be a part of the same transmission chain and were interlinked in the transmission network if they shared genetic subtypes of E. coli.

By using microbial genetics to quantify who transmits to whom independently from the behavioural data on who is in contact with whom, we were able to directly investigate how the structure of contact networks influences the structure of the transmission network. To distinguish between the effects of social and environmental contact on transmission dynamics, the transmission network was compared with two separate contact networks defined from the behavioural data: a social network based on association patterns, and a spatial network based on patterns of home‐range overlap among individuals.

We found that links in the transmission network were more likely to occur between individuals that were strongly linked in the social network. Furthermore, individuals that had more numerous connections or that occupied ‘bottleneck’ positions in the social network tended to occupy similar positions in the transmission network. No similar correlations were observed between the spatial and transmission networks. This indicates that an individual's social network position is predictive of transmission network position, which has implications for identifying individuals that function as super‐spreaders or transmission bottlenecks in the population.

These results emphasize the importance of association patterns in understanding transmission dynamics, even for environmentally transmitted microbes like E. coli. This study is the first to use microbial genetics to construct and analyse transmission networks in a wildlife population and highlights the potential utility of an approach integrating microbial genetics with network analysis.

Background/aimOccupational therapists working in mental health who experience burnout, low work engagement or poor job satisfaction are at risk of poor wellbeing at work and may be more likely to leave their jobs. The aim of this project was to explore factors associated with wellbeing at work and turnover intention in a sample of occupational therapists working in mental health.MethodsOne hundred and three occupational therapists working in mental health in Queensland completed a survey exploring work/life balance, effort invested in work, rewards received from work, wellbeing at work (job satisfaction, burnout and work engagement) and turnover intention. Analyses were conducted to explore relationships between work/life balance, effort, reward, wellbeing at work and turnover intention.ResultsAll measures of wellbeing at work were significantly associated with turnover intention. A large proportion (33%) of the variance in turnover intention was predicted by job satisfaction. Perceptions of both work/life balance and effort invested in work, as well as perceived rewards in terms of recognition, prestige and personal satisfaction were significantly associated with work‐related wellbeing scores.Conclusions and significance of the studyResults from this study deepen the understanding of factors associated with wellbeing at work and turnover intention for occupational therapists in mental health. This knowledge will support the development of interventions aimed at reducing turnover intention and enhancing retention of occupational therapists in the mental health workforce.

Background/aimOccupational therapy educators are challenged to provide students with practical experiences which prepare them for ever changing health‐care contexts on graduation. Role‐emerging placements have been widely used internationally to help meet this challenge, but research into the learning experiences of students during these innovative placements is limited. This research investigated the enablers and barriers to learning from the perspectives of students on such placements from two European universities.MethodsTwo separate qualitative studies tracked 10 final year students. Interviews explored their learning experiences prior to, during and after an eight‐ or 10‐week role‐emerging placement in a range of settings.ResultsFour themes emerged, which were (1) adapting to less doing, more thinking and planning; (2) understanding the complexity of collaboration and making it work; (3) emotional extremes; and (4) realising and using the occupational therapy perspective.ConclusionsThese placements presented a ‘roller coaster’ of authentic learning experiences which created the opportunity for students to use occupation in practice and develop skills for collaborative working in an interprofessional environment. Whereas students viewed their role‐emerging placement experiences positively, challenges included the emotional responses of students and placement pace. Findings suggest the need for supportive student placement experiences in both established and role‐emerging areas to prepare students for a range of opportunities in an uncertain future.

AbstractBackgroundTo date there is limited information documenting growth patterns in the narratives of bilingual children with and without primary language impairment (PLI).AimsThis study was designed to determine whether bilingual children with and without PLI present similar gains from kindergarten to first grade in the macro‐ and microstructure of stories told in Spanish and English.Methods & ProceduresIn this longitudinal study, 21 bilingual children identified with PLI were each matched to a bilingual typically developing (TD) peer on age, sex, non‐verbal IQ and language exposure. During their kindergarten and first‐grade years, children retold stories from wordless picture books in Spanish (L1) and English (L2).Outcomes & ResultsOverall, TD children outperformed those with PLI on measures of macro‐ and microstructure at both time points. For the macrostructure measure, the TD group made significantly larger improvements in both languages from kindergarten to first grade than the PLI group. For microstructure, the TD children made more gains on their Spanish retells than their English retells. However, the PLI children's microstructure scores did not differ from kindergarten to first grade in either language. We found that macrostructure scores in Spanish at kindergarten predicted macrostructure scores in English at first grade when English experience was held constant. However, this same relationship across languages was not evident in microstructure.Conclusions & ImplicationsTD and PLI children differed in the development of narrative macro‐ and microstructure between kindergarten and first grade. The TD bilinguals transferred conceptually dependent narrative skills easily, but then had to learn independently the nuances of each language to be successful using literate language. Because most children with PLI need more exposure to establish strong connections between their L1 and L2, they had more difficulty transferring their knowledge of literate language forms from one language to another.
Neighbourhood social ties: how much do residential, physical and virtual mobility matter?
Authors: Knies Gundi 
Published: September 2013

AbstractFollowing up on the prediction by classical sociological theorists that neighbours will become irrelevant as societies become more mobile, this research examines the strength of people's social ties with neighbours and the associations thereof with residential, physical and virtual mobility using longitudinal data for Germany. Unlike previous studies, the research considers the three forms of mobility simultaneously and contrasts its effects on social ties with neighbours to those with family. The results show that residential and physical mobility are negatively associated with social ties to neighbours and positively with ties to family. Virtual mobility does not weaken social ties with neighbours but ties with family. The positive association between mobility and social ties with family may not be strong enough to ascertain that people maintain as close social ties to others in the future as it does not outweigh the negative association with visiting neighbours.
Strangers in a strange land: coping with imprisonment as a racial or ethnic foreign national inmate

Published: September 2013

AbstractA wide range of scholarship examining the global effects of neo‐liberalism draws attention to the precarious position of individuals who are not seen as part of the social body. While immigrants, racial minorities, and common criminals are central to this discourse, relatively little research has examined how the experiences of these individuals may vary based on statuses other than citizenship when they are imprisoned. Our research focuses on the interactions (between prisoners and between prisoners and correctional staff) of a racially diverse group ofDutch foreign national prisoners incarcerated inEngland. Although all of these prisoners clearly saw themselves as ‘outsiders,’ visible minorities faced a unique set of challenges relative to their White counterparts. We consider both the practical and theoretical import of these findings.
Public sphere as assemblage: the cultural politics of roadside memorialization
Authors: Campbell Elaine 
Published: September 2013

AbstractThis paper investigates contemporary academic accounts of the public sphere. In particular, it takes stock of post‐Habermasian public sphere scholarship, and acknowledges a lively and variegated debate concerning the multiple ways in which individuals engage in contemporary political affairs. A critical eye is cast over a range of key insights which have come to establish the parameters of what ‘counts’ as a/the public sphere, who can be involved, and where and how communicative networks are established. This opens up the conceptual space for re‐imagining a/the public sphere as an assemblage. Making use of recent developments in Deleuzian‐inspired assemblage theory – most especially drawn from DeLanda's (2006) ‘new philosophy of society’ – the paper sets out an alternative perspective on the notion of the public sphere, and regards it as a space of connectivity brought into being through a contingent and heterogeneous assemblage of discursive, visual and performative practices. This is mapped out with reference to the cultural politics of roadside memorialization. However, a/the public sphere as an assemblage is not simply a ‘social construction’ brought into being through a logic of connectivity, but is an emergent and ephemeral space which reflexively nurtures and assembles the cultural politics (and political cultures) of which it is an integral part. The discussion concludes, then, with a consideration of the contribution of assemblage theory to public sphere studies. (Also see Campbell 2009a)

AbstractBackgroundRecent evidence suggests that immunogenic interventions such as vaccines and micronutrients may affect atopic sensitization and atopic disease. We aimed to determine whether neonatal BCG vaccination, vitamin A supplementation and other vaccinations affect atopy in childhood.MethodsIn Guinea–Bissau, low‐birthweight infants were randomized to early (intervention) or delayed (usual policy) BCG. A subgroup was also randomly assigned vitamin A supplementation or placebo in a two‐by‐two factorial design. Participants were followed up at age 3–9 years. The main outcome was atopy defined as skin prick test reaction ≥3 mm. Secondary outcomes were symptoms of eczema, asthma and food allergy.ResultsTwo hundred eighty‐one children had valid skin prick tests performed, and 14% (39/281) were atopic. There was no significant difference in atopy between the early and delayed BCG groups (OR, 0.71; 95% CI, 0.34–1.47). Atopy was significantly reduced in children who had responded to BCG with a scar (OR, 0.42; 0.19–0.94). Vitamin A supplementation was associated with increased atopy (OR, 2.88; 1.26–6.58), especially in those who received simultaneous BCG (5.99; 1.99–18.1, P = 0.09 for interaction between vitamin A supplementation and BCG). Early vs delayed BCG was not associated with symptoms of atopic disease, but vitamin A supplementation increased odds of wheeze within the past 12 months (OR, 2.45; 1.20–4.96).ConclusionsThere were no statistically significant effects of early vs delayed BCG on atopy or symptoms of atopic disease. Having a BCG scar was associated with reduced atopy, whereas neonatal vitamin A supplementation was associated with increased atopy.Study RegistrationClinicaltrials.gov NCT 01420705.

Published: August 2013

SummaryPulse oximetry is a standard of care during anaesthesia in high‐income countries. However, 70% of operating environments in low‐ and middle‐income countries have no pulse oximeter. The ‘Lifebox’ oximetry project set out to bridge this gap with an inexpensive oximeter meeting CE (European Conformity) and ISO (International Organization for Standardization) standards. To date, there are no performance‐specific accuracy data on this instrument. The aim of this study was to establish whether the Lifebox pulse oximeter provides clinically reliable haemoglobin oxygen saturation (SpO2) readings meeting USA Food and Drug Administration 510(k) standards. Using healthy volunteers, inspired oxygen fraction was adjusted to produce arterial haemoglobin oxygen saturation (SaO2) readings between 71% and 100% measured with a multi‐wavelength oximeter. Lifebox accuracy was expressed using bias (SpO2 − SaO2), precision (SD of the bias) and the root mean square error (Arms). Simultaneous readings of SaO2 and SpO2 in 57 subjects showed a mean (SD) bias of −0.41% (2.28%) and Arms 2.31%. The Lifebox pulse oximeter meets current USA Food and Drug Administration standards for accuracy, thus representing an inexpensive solution for patient monitoring without compromising standards.

AbstractIntroductionWe developed video‐assisted neck surgery (VANS) – a feasible, simple, and safe endoscopic thyroid procedure with cosmetic benefits – in 1998. To date, we have performed this procedure 633 times. We have also introduced the VANS method in Belarus, a country that was left contaminated by the Chernobyl nuclear disaster.MethodsFrom a mass screening, nine Belarusian patients, including two with papillary carcinoma of the thyroid, were selected to undergo an operation using the VANS method, performed by a single surgeon (author Shimizu). We compared indicating factors for minimally invasive surgery, specifically the operating time and blood loss, between the Belarusian cases and the 33 most recent cases performed at our institute in Tokyo.ResultsThe procedures in Belarus were performed under very different working conditions than in Japan. However, operating time and blood loss improved for the Belarusian cases as the surgeon gained experience in this environment; all the cosmetic outcomes were excellent. Subsequently, over a 2‐year period, surgeons in Belarus performed the VANS method, with modification, for 29 cases of thyroid tumor.ConclusionThe VANS method is easily learned by inexperienced surgeons without major technical problems.

SummaryMesenchymal stromal cell (MSC) infusions have been reported to be effective in patients with steroid‐refractory, acute graft‐versus‐host disease (aGvHD) but comprehensive data on paediatric patients are limited. We retrospectively analysed a cohort of 37 children (aged 3 months‐17 years) treated with MSCs for steroid‐refractory grade III–IV aGvHD. All patients but three received multiple MSC infusions. Complete response (CR) was observed in 24 children (65%), while 13 children had either partial (n = 8) or no response (n = 5). Cumulative incidence of transplantation‐related mortality (TRM) in patients who did or did not achieve CR was 17% and 69%, respectively (P = 0·001). After a median follow‐up of 2·9 years, overall survival (OS) was 37%; it was 65% vs. 0% in patients who did or did not achieve CR, respectively (P = 0·001). The median time from starting steroids for GvHD treatment to first MSC infusion was 13 d (range 5–85). Children treated between 5 and 12 d after steroid initiation showed a trend for better OS (56%) and lower TRM (17%) as compared with patients receiving MSCs 13–85 d after steroids (25% and 53%, respectively; P = 0·22 and 0·06, respectively). Multiple MSC infusions are safe and effective for children with steroid‐refractory aGvHD, especially when employed early in the disease course.

Until recently, hydrogen sulfide (H2S) was exclusively viewed a toxic gas and an environmental hazard, with its toxicity primarily attributed to the inhibition of mitochondrial Complex IV, resulting in a shutdown of mitochondrial electron transport and cellular ATP generation. Work over the last decade established multiple biological regulatory roles of H2S, as an endogenous gaseous transmitter. H2S is produced by cystathionine γ‐lyase (CSE), cystathionine β‐synthase (CBS) and 3‐mercaptopyruvate sulfurtransferase (3‐MST). In striking contrast to its inhibitory effect on Complex IV, recent studies showed that at lower concentrations, H2S serves as a stimulator of electron transport in mammalian cells, by acting as a mitochondrial electron donor. Endogenous H2S, produced by mitochondrially localized 3‐MST, supports basal, physiological cellular bioenergetic functions; the activity of this metabolic support declines with physiological aging. In specialized conditions (calcium overload in vascular smooth muscle, colon cancer cells), CSE and CBS can also associate with the mitochondria; H2S produced by these enzymes, serves as an endogenous stimulator of cellular bioenergetics. The current article overviews the biochemical mechanisms underlying the stimulatory and inhibitory effects of H2S on mitochondrial function and cellular bioenergetics and discusses the implication of these processes for normal cellular physiology. The relevance of H2S biology is also discussed in the context of colonic epithelial cell physiology: colonocytes are exposed to high levels of sulfide produced by enteric bacteria, and serve as a metabolic barrier to limit their entry into the mammalian host, while, at the same time, utilizing it as a metabolic ‘fuel’.Linked ArticlesThis article is part of a themed issue on Mitochondrial Pharmacology: Energy, Injury & Beyond.

Effects of an Invasive Alien Poaceae on Aquatic Macrophytes and Fish Communities in a Neotropical Reservoir

Published: September 2013

AbstractWe investigated the potential effects of an invasive alien Poaceae (Urochloa arrecta) on the abundance, richness, and composition of native macrophytes and fish. Samples were collected in patches of macrophytes dominated by the invasive species and in others dominated by a native macrophyte (Eichhornia azurea). We assessed the potential effects of these two species on macrophyte and fish abundance and richness, as well as in fish assemblage composition. The effects of both macrophytes did not differ when they were in similar, low biomasses. Consistent with our expectations, however, the abundance of native macrophytes and fish decreased with increasing U. arrecta biomass, and both assemblages were eliminated at the extreme high levels of biomass attained by this species. In contrast, E. azurea did not affect the assemblages because this native species never reached levels of biomass as high as those recorded for the invasive species. Competition for space and light most likely determines the elimination of macrophytes in patches that are extensively colonized by U. arrecta, whereas fish assemblages do not occupy these patches due most likely to the limited space available for movement and foraging. Thus, U. arrecta is a source of concern for biodiversity conservation because it has negative influences on both assemblages when it is well developed, which is true in the later stages of the invasion process.
