The Impact of Environmental Design on Doffing Personal Protective Equipment in a Healthcare Environment: A Formative Human Factors Trial
Authors: Herlihey Tracey A. , Gelmi Stefano , Cafazzo Joseph A. , Hall Trevor N. T. 
Published: May 2017

OBJECTIVE
To explore the impact of environmental design on doffing personal protective equipment in a simulated healthcare environment.

METHODS
A mixed-methods approach was used that included human-factors usability testing and qualitative questionnaire responses. A patient room and connecting anteroom were constructed for testing purposes. This experimental doffing area was designed to overcome the environmental failures identified in a previous study and was not constructed based on any generalizable hospital standard.

RESULTS
In total, 72 healthcare workers from Ontario, Canada, took part in the study and tested the simulated doffing area. The following environmental design changes were tested and were deemed effective: increasing prominence of color-coded zones; securing disinfectant wipes and hand sanitizer; outlining disposal bins locations; providing mirrors to detect possible contamination; providing hand rails to assist with doffing; and restricting the space to doff. Further experimentation and iterative design are required with regard to several important features: positioning the disposal bins for safety, decreasing the risk of contamination and user accessibility; optimal positioning of mirrors for safety; communication within the team; and positioning the secondary team member for optimal awareness. Additional design suggestions also emerged during this study, and they require future investigation.

CONCLUSIONS
This study highlights the importance of the environment on doffing personal protective equipment in a healthcare setting. Iterative testing and modification of the design of the environment (doffing area) are important to enhancing healthcare worker safety.

OBJECTIVETo determine the impact of an environmental disinfection intervention on the incidence of healthcare-associated Clostridium difficile infection (CDI).DESIGNA multicenter randomized trial.SETTINGIn total,16 acute-care hospitals in northeastern Ohio participated in the study.INTERVENTIONWe conducted a 12-month randomized trial to compare standard cleaning to enhanced cleaning that included monitoring of environmental services (EVS) personnel performance with feedback to EVS and infection control staff. We assessed the thoroughness of cleaning based on fluorescent marker removal from high-touch surfaces and the effectiveness of disinfection based on environmental cultures for C. difficile. A linear mixed model was used to compare CDI rates in the intervention and postintervention periods for control and intervention hospitals. The primary outcome was the incidence of healthcare-associated CDI.RESULTSOverall, 7 intervention hospitals and 8 control hospitals completed the study. The intervention resulted in significantly increased fluorescent marker removal in CDI and non-CDI rooms and decreased recovery of C. difficile from high-touch surfaces in CDI rooms. However, no reduction was observed in the incidence of healthcare-associated CDI in the intervention hospitals during the intervention and postintervention periods. Moreover, there was no correlation between the percentage of positive cultures after cleaning of CDI or non-CDI rooms and the incidence of healthcare-associated CDI.CONCLUSIONSAn environmental disinfection intervention improved the thoroughness and effectiveness of cleaning but did not reduce the incidence of healthcare-associated CDI. Thus, interventions that focus only on improving cleaning may not be sufficient to control healthcare-associated CDI.Infect Control Hosp Epidemiol 2017;38:777–783
On the Dichotomy between Normal and Dwarf Ellipticals
Authors: Schombert James M. 
Published: May 2017

AbstractUsing images from the SDSS DR13 library, we examine the structural properties of 374 bright (classed E0 to E6) and dwarf ellipticals [classed dE(nN) to dE(N)]. The sample combines a multicolour sample of bright ellipticals (252 galaxies with $M_{\text{g}} < -20$) with a new sample of faint ellipticals (60 galaxies with $M_{\text{g}} > -20$) which overlaps the dwarf elliptical sample (62 galaxies) in luminosity and size. The faint ellipticals extend the linear structural correlations found for bright ellipticals into parameter space not occupied by dwarf ellipticals indicating a dichotomy exists between the two types. In particular, many faint ellipticals have significantly higher effective surface brightnesses compared to dwarf ellipticals which eliminates any connection at a set stellar mass. Template analysis of the three subsets of ellipticals demonstrates that the bright and faint ellipticals follow the same trends of profile shape (weak homology), but that dwarf ellipticals form a separate and distinct structural class with lower central surface brightnesses and extended isophotal radii.

AbstractAmong other zooarchaeological remains, terrestrial snails’ shells from theThaumastusandMegalobulimusgenera are found in some Brazilian shellmounds, presenting a potential substitute for charcoal in radiocarbon dating analyses, as reliable representatives of the atmospheric carbon isotopic ratio. In this paper, we present statistically similar results of both charcoal and land snails samples from the same archaeological contexts in three settlements on the coast of Rio de Janeiro. The Manitiba I shellmound results range from 4.2 to 3.7 ka cal BP (95.4%), contemporary with the Saquarema shellmound, occupied during the period from 4.3 to 3.6 ka cal BP (95.4%). For the Usiminas shellmound, two groups of samples revealed different periods of time for two occupational layers from 2.3 to 2.1 ka cal BP (95.4%) and from 1.6 and 1.3 ka cal BP (95.4%). A model constraining each group of samples to within a single phase has a general agreement of 97% with only two outliers out of 22 dates, yielding minimum individual agreement of 74% and 7% posterior outlier probability for Saquarema shells. These are good examples of sites in which the occupation chronology can be successfully obtained by the radiocarbon dating of land snails.

Published: May 2017

AbstractAccurate data on dietary intake are important for public health, nutrition and agricultural policy. The National Sample Survey is widely used by policymakers in India to estimate nutritional outcomes in the country, but has not been compared with other dietary data sources. To assess relative differences across available Indian dietary data sources, we compare intake of food groups across six national and sub-national surveys between 2004 and 2012, representing various dietary intake estimation methodologies, including Household Consumption Expenditure Surveys (HCES), FFQ, food balance sheets (FBS), and 24-h recall (24HR) surveys. We matched data for relevant years, regions and economic groups, for ages 16–59. One set of national HCES and the 24HR showed a decline in food intake in India between 2004–2005 and 2011–2012, whereas another HCES and FBS showed an increase. Differences in intake were smallest between the two HCES (1 % relative difference). Relative to these, FFQ and FBS had higher intake (13 and 35 %), and the 24HR lower intake (−9 %). Cereal consumption had high agreement across comparisons (average 5 % difference), whereas fruit and nuts, eggs, meat and fish and sugar had the least (120, 119, 56 and 50 % average differences, respectively). Spearman’s coefficients showed high correlation of ranked food group intake across surveys. The underlying methods of the compared data highlight possible sources of under- or over-estimation, and influence their relevance for addressing various research questions and programmatic needs.

Published: May 2017

AbstractStudies have investigated the potential protective effects that diet may have on late-life depression incidence. This disorder can, however, affect the person’s food intake, widely known as the reverse causality hypothesis of depression. To test this hypothesis, we compared mean nutrient intakes from three 24-h recalls during the year depression was detected (Geriatric Depression Scale ≥11 or antidepressant medication) with intakes from 1 year earlier among community-dwelling older adults (67–83 years) followed up annually in the 4-year Québec Longitudinal Study on Nutrition and Aging, who were free of depression and cognitive impairment at baseline. Participants (n158, 64·4 % female) who became depressed and had data available for all follow-up years were matched by age group and sex with non-depressed participants. General linear mixed models were adjusted for percentage changes in physical activity, functional autonomy and stressful life events reported at the time of positive screening. A significant group effect for the dietary intake of all three B-vitamins was observed, as depression cases had consistently lower dietary intakes than controls (P<0·01). Over time, intakes of dietary vitamin B12declined within depressed participants in bivariate analysis, but there was no time×group effect for any nutrient tested in the multivariate analyses. Intakes of energy, protein, saturated fat and total dietary fibre did not change in casesv. controls. Among community-dwelling older adults, declines in dietary vitamins B6, B12and folate may precede depression incidence. To help preventative efforts by programmes and practitioners, longitudinal cohorts of longer duration should investigate the extent of the decline in dietary intakes relative to the time of depression.
U–Th–Pb systematics in zircon and apatite from the Chicxulub impact crater, Yucatán, Mexico

Published: May 2017

AbstractThis work presents a systematic study of zircon and apatite in melt-bearing impactites from the annular trough of the ~180 km and ~66.04 Ma Chicxulub impact crater, Yucatán, Mexico, usingin situlaser ablation – inductively coupled plasma mass spectrometry, in which the petrologic context of the analysed minerals was assessed. Geochronologic U–Pb results for variably shocked zircon from the Yaxcopoil-1 core, including monocrystalline grains and neocrystallised granular aggregates, yielded a discordant array of ages representing the Early Palaeozoic age of the crystalline–metamorphic Maya block in the crater basement and the timing of the Chicxulub impact, respectively, and provide evidence for impact-induced resetting of the U–Pb system. Zircon and fluor-chlorapatite from the Yaxcopoil-1 core, and fluorapatite in clasts of impact melt from the Yucatán-6 core have low206Pb/204Pb, suggesting the presence of detectable common Pb. The Chicxulub impactites were altered in an initially hot hydrothermal system that lasted up to ~2 Myr; locally, Pb-rich sulphides precipitated. Hydrothermal conditions did not reset the U–Th–Pb systematics of relict zircon, however, due to elevated closure temperatures for Pb diffusion at the fast cooling rates associated with the crater locations of the Yucatán-6 and Yaxcopoil-1 boreholes. Thus, the zircon preserves pre-impact and impact-related ages, rather than those of the hydrothermal system. In contrast, no useful geochronologic information was obtained from relict apatite, because common Pb in these grains overwhelmed radiometrically derived isotope ratios.
Peritonsillar abscess: epidemiology and relationship with climate variations
Authors: Freire G S M , dos Santos J H Z , Rolón P A , Pinheiro G B , Sampaio A L L 
Published: May 2017

AbstractBackground:Peritonsillar abscess is the most common deep infection of the head and neck in young adults. It is considered a purulent complication of acute tonsillitis, but other mechanisms have been proposed. There is no consensus as to whether seasonality affects peritonsillar abscess incidence.Methods:This observational, descriptive, retrospective study explored the epidemiology of peritonsillar abscess and its relationship with seasonality. The cases were selected from the emergency otolaryngology service of a tertiary hospital.Results:The sample comprised 528 patients (42.61 per cent males, mean age = 26.63 years). A moderate positive correlation was found between peritonsillar abscess incidence and monthly average temperature. No associations were found with insolation, precipitation or humidity.Conclusion:In this sample, peritonsillar abscess was more likely to occur in warmer months. The findings corroborate the theory that peritonsillar abscess is not a direct complication of acute tonsillitis and may improve understanding of peritonsillar abscess aetiology.

Published: May 2017

AbstractUsing the Safe Islands for Seabirds LIFE project as a case study, we assessed the socio-economic impact of a nature conservation project on the local community, focusing on the wealth created and the jobs supported directly and indirectly by the project. The Safe Islands for Seabirds project took place during 2009–2012, mainly on Corvo Island, the smallest and least populated island of Portugal's Azores Archipelago. To assess the impact of the project we used a combination of methods to analyse the project expenditure, the jobs created directly as a result of it, and, by means of multipliers, the incomes and jobs it supported indirectly. We estimate that during 2009–2012 direct expenditure of EUR 344,212.50 from the project increased the gross domestic product of the Azorean region by EUR 206,527.50. Apart from the 4.5 jobs created directly by the project, it also supported indirectly the equivalent of 1.5–2.5 full-time jobs. The project also provided the opportunity to preserve and promote natural amenities important for the quality of life of the local community. Our findings show that a nature conservation project can have positive economic impacts, and we recommend the creation of a standardized tool to calculate in a straightforward but accurate manner the socio-economic impacts of conservation projects. We also highlight the need to design projects that support local economies.
Listening to the Kids: The Value of Childhood Palaeopathology for the Study of Rural Roman Britain
Authors: Rohnbogner Anna 
Published: May 2017

ABSTRACTChildhood palaeopathology remains an underutilised resource in the study of Roman Britain, particularly for exploring the lives of the rural population. Lesions in child skeletons provide unique insights into past lifeways and population health, as adverse environmental conditions translate more readily into the osteological record of these vulnerable members of society. To demonstrate the range of information gleaned from the children, 1,279 non-adults (0–17 years) from 26 first- to fifth-century urban and rural settlements were analysed, comparing morbidity and mortality in the most comprehensive study to date. The distribution of ages-at-death suggests migration between country and town, the latter presenting a stressful and unsanitary environment. However, as demonstrated by high rates of metabolic disease and infections, life in the countryside was hampered by demanding physical labour and potentially oppressive conditions with restricted access to resources.
Product of Simplices and sets of positive upper density in ℝd
Authors: LYALL NEIL , MAGYAR ÁKOS 
Published: May 2017

AbstractWe establish that any subset of ℝd of positive upper Banach density necessarily contains an isometric copy of all sufficiently large dilates of any fixed two-dimensional rectangle provided d ⩾ 4.We further present an extension of this result to configurations that are the product of two non-degenerate simplices; specifically we show that if Δk1 and Δk2 are two fixed non-degenerate simplices of k1 + 1 and k2 + 1 points respectively, then any subset of ℝd of positive upper Banach density with d ⩾ k1 + k2 + 6 will necessarily contain an isometric copy of all sufficiently large dilates of Δk1 × Δk2.A new direct proof of the fact that any subset of ℝd of positive upper Banach density necessarily contains an isometric copy of all sufficiently large dilates of any fixed non-degenerate simplex of k + 1 points provided d ⩾ k + 1, a result originally due to Bourgain, is also presented.
Evaluating the Behaviour of Chinese Stakeholders Engaged in Large Hydropower Projects in Asia and Africa
Authors: Tan-Mullins May , Urban Frauke , Mang Grace 
Published: May 2017

AbstractHydropower dams are back in the spotlight owing to a shifting preference for low carbon energy generation and their possible contribution to mitigating climate change. At the forefront of the renaissance of large hydropower dams are Chinese companies, as the builders of the world's largest dams at home and abroad, opening up opportunities for low- and middle-income countries. However, large hydropower dams, despite their possible developmental and carbon reduction contributions, are accompanied by huge economic costs, profound negative environmental changes and social impacts. Using fieldwork data from four hydropower projects in Ghana, Nigeria, Cambodia and Malaysia, this paper evaluates the behaviour of Chinese stakeholders engaged in large hydropower projects in Asia and Africa. We do this by first exploring the interests of the different Chinese stakeholders and then by investigating the wider implications of these Chinese dams on the local, national and international contexts. The paper concludes that hydropower dams will continue to play a prominent role in future efforts to increase energy security and reduce energy poverty worldwide, therefore the planning, building and mitigation strategies need to be implemented in a more sustainable way that takes into account national development priorities, the needs of local people and the impacts on natural habitats.

SUMMARYThe purpose of this study was to describe prevalence and spatial distribution of Coxiella burnetii infections in dairy cow sheds in Latvia and to investigate risk factors contributing to C. burnetii infections. Blood serum samples from abortion cases from 1010 sheds have been tested by ELISA for the presence of C. burnetii antibodies and bulk tank milk (BTM) samples from 252 sheds have been tested by real time polymerase chain reaction and ELISA for the presence of C. burnetii DNA and antibodies. Prevalence of C. burnetii antibody-positive sheds in cases of abortion was 13·4%. A total of 10·7% and 13·2% of dairy cow sheds tested positive for the presence of C. burnetii DNA and antibodies in BTM, respectively. Two distinct areas of clustering of test-positive dairy cattle sheds were identified by spatial scan statistics of abortion cases and randomly sampled BTM samples. Three factors were identified as significantly contributing to the risk of C. burnetii DNA presence in BTM – number of cattle in shed (>200 animals/shed) (OR 3·93), location of the shed within risk area in Northern Latvia (OR 8·29) and for the first time, purchasing cattle from abroad has been shown to significantly increase risk (OR 2·68) of C. burnetii infection in dairy cows in Latvia.
Nutritional aspects of commercially prepared infant foods in developed countries: a narrative review
Authors: Maslin Kate , Venter Carina 
Published: May 2017

AbstractNutritional intake during infancy is a critical aspect of child development and health that is of significant public health concern. Although there is extensive research on breast-feeding and timing of solid food introduction, there is less evidence on types of solid foods fed to infants, specifically commercially prepared infant foods. The consumption of commercially prepared infant foods is very prevalent in many developed countries, exceeding the consumption of homemade foods in some situations. Although these food products may have practical advantages, there are concerns about their nutritional composition, sweet taste, bioavailability of micronutrients, diversity of ingredients and long-term health effects. The extent that the manufacturing, fortification and promotion of these products are regulated by legislation varies between countries and regions. The aim of the present narrative review is to investigate, appraise and summarise these aspects. Overall there are very few studies directly comparing homemade and commercial infant foods and a lack of longitudinal studies to draw firm conclusions on whether commercial infant foods are mostly beneficial or unfavourable to infant health.

AbstractAnomalous aortic origin of the coronary arteries is associated with exercise-induced ischaemia, leading some physicians to restrict exercise in patients with this condition. We sought to determine whether exercise restriction was associated with increasing body mass index over time. From 1998 to 2015, 440 patients ⩽30 years old were enrolled into an inception cohort. Exercise-restriction status was documented in 143 patients. Using linear mixed model repeated-measures regression, factors associated with increasing body mass index z-score over time, including exercise restriction and surgical intervention as time-varying covariates, were investigated. The 143 patients attended 558 clinic visits for which exercise-restriction status was recorded. The mean number of clinic visits per patient was 4, and the median duration of follow-up was 1.7 years (interquartile range (IQR) 0.5–4.4). The median age at first clinic visit was 10.3 years (IQR 7.1–13.9), and 71% (101/143) were males. All patients were alive at their most recent follow-up. At the first clinic visit, 54% (78/143) were exercise restricted, and restriction status changed in 34% (48/143) during follow-up. The median baseline body mass index z-score was 0.2 (IQR 0.3–0.9). In repeated-measures analysis, neither time-related exercise restriction nor its interaction with time was associated with increasing body mass index z-score. Surgical intervention and its interaction with time were associated with decreasing body mass index z-score. Although exercise restriction was not associated with increasing body mass index over time, surgical intervention was associated with decreasing body mass index z-score over time in patients with anomalous aortic origin of the coronary arteries.
