AbstractThe experiment reported in this research paper aimed to determine whether clinical and subclinical effects on cattle were similar if provided with isoenergetic and isonitrogenous challenge diets in which carbohydrate sources were predominantly starch or sugar. The study was a 3 × 3 Latin square using six adult Jersey cows with rumen cannulae, over 9 weeks. In the first 2 weeks of each 3 week experimental period cows were fed with a maintenance diet and, in the last week, each animal was assigned to one of three diets: a control diet (CON), being a continuation of the maintenance diet; a high starch (HSt) or a high sugar (HSu) diet. Reticuloruminal pH and motility were recorded throughout the study period. Blood and ruminal samples were taken on day-1 (TP-1), day-2 (TP-2) and day-7 (TP-7) of each challenge week. Four clinical variables were recorded daily: diarrhoea, inappetence, depression and ruminal tympany. The effects of treatment, hour of day and day after treatment on clinical parameters were analysed using linear mixed effects (LME) models. Although both challenge diets resulted in a decline in pH, an increase in the absolute pH residuals and an increase in the number of minutes per day under pH 5.8, systemic inflammation was only detected with the HSt diet. The challenge diets differentially modified amplitude and period of reticuloruminal contractions compared with CON diet and both were associated with an increased probability of diarrhoea. The HSu diet reduced the probability of an animal consuming its complete allocation. Because the challenge diets were derived from complex natural materials (barley and molasses respectively), it is not possible to assign all the differential effects to the difference in starch and sugar concentration: non-starch components of barley or non-sugar components of molasses might have contributed to some of the observations. In conclusion, substituting much of the starch with sugar caused no substantial reduction in the acidosis load, but inflammatory response was reduced while feed rejection was increased.

AbstractDermanyssus gallinae(De Geer 1778), commonly named the poultry red mite (PRM), is considered to be the most harmful ectoparasite in poultry farms in Europe. This species feeds on the blood of laying hens, but spends most of its time hidden in cracks and crevices around hen nests. To control PRM populations in poultry houses, chemical pesticides are currently used; however, concern is growing regarding the harmful residues found in eggs and hens, along with the increased resistance of mites against several compounds. Alternatives to synthetic compounds are now being explored, including vaccines, biological control, physical control and semiochemical control based on the chemical ecology of PRM. This review focused on the different volatile organic compounds (VOCs) identified fromD. gallinaeand other mite species that have been discovered to control them. Pheromones (aggregation pheromone, sex pheromone and alarm pheromone) and kairomones promoting attraction behaviour inD. gallinaeand other mite species are presented, while VOCs from essential oils and plant extracts with repellent properties are also explored. Finally, devices using VOCs on PRM in the field are described, with devices that have been tested on other Acari species being mentioned as potential directions for the future control of PRM.

AbstractBackgroundNeuroticism is associated with the onset and maintenance of a number of mental health conditions, as well as a number of deleterious outcomes (e.g. physical health problems, higher divorce rates, lost productivity, and increased treatment seeking); thus, the consideration of whether this trait can be addressed in treatment is warranted. To date, outcome research has yielded mixed results regarding neuroticism's responsiveness to treatment, perhaps due to the fact that study interventions are typically designed to target disorder symptoms rather than neuroticism itself. The purpose of the current study was to explore whether a course of treatment with the unified protocol (UP), a transdiagnostic intervention that was explicitly developed to target neuroticism, results in greater reductions in neuroticism compared to gold-standard, symptom focused cognitive behavioral therapy (CBT) protocols and a waitlist (WL) control condition.MethodPatients with principal anxiety disorders (N = 223) were included in this study. They completed a validated self-report measure of neuroticism, as well as clinician-rated measures of psychological symptoms.ResultsAt week 16, participants in the UP condition exhibited significantly lower levels of neuroticism than participants in the symptom-focused CBT (t(218) = −2.17, p = 0.03, d = −0.32) and WL conditions(t(207) = −2.33, p = 0.02, d = −0.43), and these group differences remained after controlling for simultaneous fluctuations in depression and anxiety symptoms.ConclusionsTreatment effects on neuroticism may be most robust when this trait is explicitly targeted.

Published: April 2020

BackgroundTranscatheter aortic-valve implantation (TAVI) has become an essential alternative to surgical aortic-valve replacement in the treatment of symptomatic severe aortic stenosis, and this procedure requires technical expertise. The aim of this study was to identify prospective studies on TAVI from the past 10 years, and then to analyze the quality of information reported about the learning curve.Materials and methodsA systematic review of articles published between 2007 and 2017 was performed using PubMed and the EMBASE database. Prospective studies regarding TAVI were included. The quality of information reported about the learning curve was evaluated using the following criteria: mention of the learning curve, the description of a roll-in phase, the involvement of a proctor, and the number of patients suggested to maintain skills.ResultsA total of sixty-eight studies met the selection criteria and were suitable for analysis. The learning curve was addressed in approximately half of the articles (n= 37, 54 percent). However, the roll-in period was mentioned by only eight studies (12 percent) and with very few details. Furthermore, a proctorship was disclosed in three articles (4 percent) whereas twenty-five studies (37 percent) included authors that were proctors for manufacturers of TAVI.ConclusionMany prospective studies on TAVI over the past 10 years mention learning curves as a core component of successful TAVI procedures. However, the quality of information reported about the learning curve is relatively poor, and uniform guidance on how to properly assess the learning curve is still missing.

AbstractBioremediation has been proposed as a means of dealing with oil spills on the continent. However, the introduction of non-native organisms, including microbes, even for this purpose would appear to breach the terms of the Environmental Protocol to the Antarctic Treaty. This study therefore aimed to optimize the growth conditions and diesel degradation activity of the Antarctic native bacteria Arthrobacter spp. strains AQ5-05 and AQ5-06 through the application of a one-factor-at-a-time (OFAT) approach. Both strains were psychrotolerant, with the optimum temperature supporting diesel degradation being 10–15°C. Both strains were also screened for biosurfactant production and biofilm formation. Their diesel degradation potential was assessed using Bushnell–Haas medium supplemented with 0.5% (v/v) diesel as the sole carbon source and determined using both gravimetric and gas chromatography and mass spectrophotometry analysis. Strain AQ5-06 achieved 37.5% diesel degradation, while strain AQ5-05 achieved 34.5% diesel degradation. Both strains produced biosurfactants and showed high biofilm adherence. Strains AQ5-05 and AQ5-06 showed high cellular hydrophobicity rates of 73.0% and 81.5%, respectively, in hexadecane, with somewhat lower values of 60.5% and 70.5%, respectively, in tetrahexadecane. Optimized conditions identified via OFAT increased diesel degradation to 41.0% and 47.5% for strains AQ5-05 and AQ5-06, respectively. Both strains also demonstrated the ability to degrade diesel in the presence of heavy metal co-pollutants. This study therefore confirms the potential use of these cold-tolerant bacterial strains in the biodegradation of diesel-polluted Antarctic soils at low environmental temperatures.

AbstractThis article captures the webinar narrative on March 31, 2020 of four expert panelists addressing three questions on the current coronavirus disease 2019 (COVID-19) pandemic. Each panelist was selected for their unique personal expertise, ranging from front-line emergency physicians from multiple countries, an international media personality, former director of the US Strategic National Stockpile, and one of the foremost international experts in disaster medicine and public policy. The forum was moderated by one of the most widely recognized disaster medical experts in the world. The four panelists were asked three questions regarding the current pandemic as follows:1.What do you see as a particular issue of concern during the current pandemic?2.What do you see as a particular strength during the current pandemic?3.If you could change one thing about the way that the pandemic response is occurring, what would you change?
Challenging pollution and the balance problem from rare earth extraction: how recycling and environmental taxation matter
Authors: Ba Bocar Samba , Combes-Motel Pascale , Schwartz Sonia 
Published: April 2020

AbstractRare earth element extraction induces environmental damages and the balance problem. In this article, we show that recycling can challenge both problems in a two-period framework. We also find other results depending on the amount of scrap that can be recycled. If the recycling activity is not limited by available scrap, it does not change extraction in the first period. Environmental taxes on extracted quantities reduce extraction and favor recycling. But if the recycling is limited, the extractor reduces extraction in period one, adopting a foreclosure strategy, and environmental taxes can decrease recycling. In all cases, environmental taxes are never equal to the marginal damage from pollution, in order to take into account the recycling effect.
More to offer than books: stakeholder perceptions of a public library-based meal programme
Authors: De La Cruz Monica M , Phan Kimmy , Bruce Janine S 
Published: April 2020

AbstractObjective:To examine the perspectives of librarians and staff aboutLunch at the Library, a library-based summer meal programme for children. The study examines: (i) motivating factors behind implementing the meal programme; (ii) issues of feasibility; and (iii) perceived programme outcomes.Design:One-on-one semi-structured interviews with library stakeholders (librarians and staff) from a purposeful sample of California libraries.Setting:Twenty-two library jurisdictions across California that implemented theLunch at the Librarysummer meal programme in 2015 in areas of high financial need.Participants:Twenty-five library stakeholders representing twenty-two of the thirty-three Californian library jurisdictions that implementedLunch at the Libraryat their sites.Results:Library stakeholders recognised the need for a child meal programme during summer. Despite lack of sufficient resources and personnel, they were motivated to implement the programme not only to fill a community need but also to ensure children at their libraries were primed for learning over the summer. Library stakeholders also perceived the public library’s changing role in society as shifting from reference provision to social service provision either directly or by referral.Conclusions:The public library is an ideal place to provide social services because of its accessibility to all. Librarians and library staff are motivated to address the social needs of their communities. This study demonstrates the feasibility of implementing new social programmes at public libraries. Funding to support these programmes would increase the library’s capacity to address other community needs.
The importance of school lunches to the overall dietary intake of children in Sweden: a nationally representative study
Authors: Eustachio Colombo Patricia , Patterson Emma , Elinder Liselotte S , Lindroos Anna Karin 
Published: April 2020

AbstractObjective:School lunches have potential to foster healthy diets in all children, but data on their importance are relatively scarce. The current study aimed to describe the dietary intake from school lunches by sex and school grade, and to assess how the daily intake, school lunch intake and the daily intake provided by lunch differ by sex and parental education.Design:Cross-sectional. All foods and drinks consumed for 1–3 weekdays were self-reported. Energy, absolute and energy-adjusted intakes of nutrients and food groups were calculated per weekday and per school lunch. Mixed-effects linear models assessed sociodemographic differences in dietary intakes. Nutrient and energy density at lunch and during the rest of the day were compared.Setting:Seventy-nine Swedish primary schools.Participants:Pupils in grades 5 and 8 (N2002), nationally representative.Results:Lunch provided around half of daily vegetable intake and two-thirds of daily fish intake. Nutrient density was higher and energy density lower at lunch compared with the rest of the day (P< 0·001). Boys had greater energy-adjusted intakes of red/processed meat and lower intakes of vegetables and dietary fibre compared with girls (P< 0·001), overall and at lunch. Daily energy-adjusted intakes of most nutrients/food groups were lower for pupils of lower-educated parents compared with pupils of parents with higher education, but at lunch, only Fe and fibre intakes were significantly lower in this group.Conclusions:School lunches are making a positive contribution to the diets of Swedish children and may mitigate well-established sex differences and social inequalities in dietary intake.

AbstractClinical and experimental studies show an association between maternal periodontitis and adverse outcomes during gestation. On the other hand, there were no studies evaluating the impact of maternal periodontitis on the offspring. Thus, our objective was to investigate the repercussion of maternal periodontitis on the development of asthma in the offspring. Pregnant rats were submitted or not to periodontitis by ligature technique. Thirty days after birth, the puppies were sensitized and challenged with ovalbumin (OVA) in order to induce asthmatic response. Our results showed that maternal periodontitis reduced cellular infiltrate in the parenchyma of offspring, tracheal responsiveness, lung edema, and anti-OVA antibodies, without alter mucus as well as cytokines production. We concluded that periodontitis has relevant impact on the offspring’s immune system, blunting the response to allergic and inflammatory stimulus. This study shows the important role of oral health during pregnancy and opens possibilities for future studies in order to explain the effects of periodontitis during pregnancy in the offspring.
DOHaD in low- and middle-income countries: a systematic review exploring gaps in DOHaD population studies
Authors: Tu’akoi Siobhan , Vickers Mark H. , Bay Jacquie L. 
Published: April 2020

AbstractLow- and middle-income countries (LMICs) are disproportionately affected by non-communicable diseases (NCDs), accounting for more than 80% of NCD-related deaths globally. Research into early-life influences on these diseases via the developmental origins of health and disease (DOHaD) paradigm has informed health promotion interventions and policies focused on optimising early-life health. However, little is known about where this research occurs and whether it reaches and reflects the countries most affected by NCDs. This review searched for DOHaD studies that investigated relationships between factors during pregnancy and at birth, with later-life NCD incidence, risk and related mortality. The aim of this review was to identify where DOHaD research has been conducted and whether this focus is appropriate and relevant, given the differential burden of NCDs. Embase, MEDLINE and Scopus were searched, and eligibility screening processes identified 136 final articles. This review found that 49.7% of DOHaD research was conducted on populations within Western Europe, 15.9% in East Asia, 12.7% in North America, 8.3% in Latin America and the Caribbean, and fewer in Australasia, South Asia, the Middle East, the Africas, and Central Asia. When categorised by income, this review found that 76.4% of studies were based in high-income countries, 19.1% in upper-middle-income and 4.5% in lower-middle-income countries. No studies were based in low-income countries. There is therefore a marked disconnect between where DOHaD research is undertaken and where the greatest NCD disease burden exists. Increasing DOHaD research capacity in LMICs is crucial to informing local strategies that can contribute to reducing the incidence of NCDs.
Crustal Structure of Sri Lanka Derived From Joint Inversion of Surface Wave Dispersion and Receiver Functions Using a Bayesian Approach

Published: April 2020

AbstractWe study the crustal structure of Sri Lanka by analyzing data from a temporary seismic network deployed in 2016–2017 to shed light on the amalgamation process from a geophysical perspective. Rayleigh wave phase dispersion curves from ambient noise cross correlation and receiver functions were jointly inverted using a transdimensional Bayesian approach. The Moho depths in Sri Lanka range between 30 and 40 km, with the thickest crust (38–40 km) beneath the central Highland Complex (HC). The thinnest crust (30–35 km) is found along the west coast, which experienced crustal thinning associated with the formation of the Mannar Basin. VP/VS ratios lie within a range of 1.60–1.82 and predominantly favor a felsic to intermediate bulk crustal composition with a significant silica content of the rocks. A major intracrustal (18–27 km), slightly westward dipping (∼4.3°) interface with high VS (∼4 km/s) underneath is prominent in the central HC, continuing into the western Vijayan Complex (VC). The discontinuity might have been part of the respective units prior to the collision and could be an indicator for the proposed tilting of the Wanni Complex/HC crustal sections. It might also be related to the deep crustal HC/VC thrust contact with the VC as an indenting promontory of high VS. A low‐velocity zone in the central HC could have been caused by fluid influx generated by the thrusting process.
Fate of Internal Waves on a Shallow Shelf

Published: April 2020

AbstractInternal waves strongly influence the physical and chemical environment of coastal ecosystems worldwide. We report novel observations from a distributed temperature sensing (DTS) system that tracked the transformation of internal waves from the shelf break to the surf zone over a narrow shelf slope region in the South China Sea. The spatially continuous view of temperature fields provides a perspective of physical processes commonly available only in laboratory settings or numerical models, including internal wave reflection off a natural slope, shoreward transport of dense fluid within trapped cores, and observations of internal rundown (near‐bed, offshore‐directed jets of water preceding a breaking internal wave). Analysis shows that the fate of internal waves on this shelf—whether transmitted into shallow waters or reflected back offshore—is mediated by local water column density structure and background currents set by the previous shoaling internal waves, highlighting the importance of wave‐wave interactions in nearshore internal wave dynamics.
Structure and Seasonal Variation of the Indian Ocean Tropical Gyre Based on Surface Drifters

Published: April 2020

AbstractUsing the Gauss‐Markov decomposition method, this study investigates the mean structure and seasonal variation of the tropical gyre in the Indian Ocean based on the observations of surface drifters. In the climatological mean, the clockwise tropical gyre consists of the equatorial Wyrtki Jets (WJs), the South Equatorial Current (SEC), and the eastern and western boundary currents. This gyre system redistributes the water mass over the entire tropical Indian Ocean basin. Its variations are associated with the monsoon transitions, featuring a typical clockwise pattern in the boreal spring and fall seasons. The relative importance of the geostrophic and Ekman components of the surface currents as well as the role of eddy activity were further examined. It was found that the geostrophic component dominates the overall features of the tropical gyre, including the SEC meandering, the broad eastern boundary current, and the axes of the WJs in boreal spring and fall, whereas the Ekman component strengthens the intensity of the WJs and SEC. Eddies are active over the southeastern tropical Indian Ocean and transport a warm and fresh water mass westward, with direct impact on the southern branch of the tropical gyre. In particular, the trajectories of drifters reveal that during strong Indian Ocean Dipole or El Niño‐Southern Oscillation events, long‐lived eddies were able to reach the southwestern Indian Ocean with a moving speed close to that of the first baroclinic Rossby waves.
