Infant formula feeding practices in a prospective population based study

Background: It is recommended that formula-fed infants are given standard whey-based infant formula throughout the first year of life, unless otherwise advised by healthcare professionals. To our knowledge it has not yet been explored if parents are using a whey-based infant formula throughout the first 12 months of life. Reasons for parental choice of formula are also unknown. Therefore, the objective of this paper was to describe parental administration of whey-based and non whey-based infant formula in the first year of life. Methods: Data collected as part of the Cork BASELINE Birth Cohort Study examined infant feeding practices at 2, 6 and 12 months of age. Descriptive analysis explored infant feeding practices and parental reasons for changing from a whey-based to a non whey-based infant formula. Multiple logistic regression investigated parental and infant characteristics associated with the use of whey-based infant formula. Results: In total, 62.4%, 40.4% and 12.8% parent(s) at 2, 6 and 12 months, respectively, gave their infant whey-based infant formula. No parental or infant characteristic was found to consistently influence the use of whey-based infant formula. The most common reason reported by parent(s) for changing their infant’s formula to a non whey-based formula was that they perceived their baby as being hungry. Conclusion: The majority of parent(s) commence their infants on whey-based formula, but most change to non whey-based formula before 12 months of age. Parental perception of infant satiety and not healthcare advice was the most common reason for changing from a whey-based to a non whey-based infant formula. Additional research is now required to investigate the effect of whey-based and non whey-based infant formula on infant growth

A collaborative approach to designing an intervention for patients with atrial fibrillation

Background: Patients diagnosed with atrial fibrillation (AF) have an increased risk of stroke, and need to adhere to treatment and lifestyle recommendations to reduce likelihood of adverse events. AF patients are often highly symptomatic relying on subjective indicators to manage their illness. Method: Intervention design comprised two parallel processes: (1) targeting theoretical constructs within the common sense model and (2) piloting intervention materials, using expert patient panels (2 focus groups with 6 patients), individual patient interviews (n 1⁄4 6) and expert cardiologist feedback. Findings: Each component of the intervention was adapted and moderated following patient and cardiologist feedback, e.g. presentation of risk information. The final intervention comprises DVD (including patient narratives), worksheets, patient education booklet and a self-monitoring diary. It is currently being evaluated in a randomised control trial [ISRCTN93952605]. Discussion: Health psychologists play an intrinsic role in this collaborative process, whereby intervention development evolves through theoretical and pragmatic piloting.peer-reviewe

Protocol for the development of a salutogenic intrapartum core outcome set (SIPCOS)

Background: Maternity intrapartum care research and clinical care more often focus on outcomes that minimise or prevent adverse health rather than on what constitutes positive health and wellbeing (salutogenesis). This was highlighted recently in a systematic review of reviews of intrapartum reported outcomes where only 8% of 1648 individual outcomes, from 102 systematic reviews, were agreed as being salutogenically-focused. Added to this is variation in the outcomes measured in individual studies rendering it very difficult for researchers to synthesise, fully, the evidence from studies on a particular topic. One of the suggested ways to address this is to develop and apply an agreed standardised set of outcomes, known as a ‘core outcome set’ (COS). In this paper we present a protocol for the development of a salutogenic intrapartum COS (SIPCOS) for use in maternity care research and a SIPCOS for measuring in daily intrapartum clinical care. Methods: The study proposes three phases in developing the final SIPCOSs. Phase one, which is complete, involved the conduct of a systematic review of reviews to identify a preliminary list of salutogenically-focused outcomes that had previously been reported in systematic reviews of intrapartum interventions. Sixteen unique salutogenically-focused outcome categories were identified. Phase two will involve prioritising these outcomes, from the perspective of key stakeholders (users of maternity services, clinicians and researchers) by asking them to rate the importance of each outcome for inclusion in the SIPCOSs. A final consensus meeting (phase three) will be held, bringing international stakeholders together to review the preliminary SIPCOSs resulting from the survey and to agree and finalise the final SIPCOSs for use in future maternity care research and daily clinical care. Discussion: The expectation in developing the SIPCOSs is that they will be collected and reported in all future studies evaluating intrapartum interventions and measured/recorded in future intrapartum clinical care, as routine, alongside other outcomes also deemed important in the context of the study or clinical scenario. Using the SIPCOSs in this way, will promote and encourage standardised measurements of positive health outcomes in maternity care, into the future

The role of sand lances (Ammodytes sp.) in the Northwest Atlantic ecosystem: a synthesis of current knowledge with implications for conservation and management. Fish and Fisheries, 00, (2020): 1-34, doi:10.1111/faf.12445.The American sand lance (Ammodytes americanus, Ammodytidae) and the Northern sand lance (A. dubius, Ammodytidae) are small forage fishes that play an important functional role in the Northwest Atlantic Ocean (NWA). The NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing and energy development. We need a better understanding of the biology, population dynamics and ecosystem role of Ammodytes to inform relevant management, climate adaptation and conservation efforts. To meet this need, we synthesized available data on the (a) life history, behaviour and distribution; (b) trophic ecology; (c) threats and vulnerabilities; and (d) ecosystem services role of Ammodytes in the NWA. Overall, 72 regional predators including 45 species of fishes, two squids, 16 seabirds and nine marine mammals were found to consume Ammodytes. Priority research needs identified during this effort include basic information on the patterns and drivers in abundance and distribution of Ammodytes, improved assessments of reproductive biology schedules and investigations of regional sensitivity and resilience to climate change, fishing and habitat disturbance. Food web studies are also needed to evaluate trophic linkages and to assess the consequences of inconsistent zooplankton prey and predator fields on energy flow within the NWA ecosystem. Synthesis results represent the first comprehensive assessment of Ammodytes in the NWA and are intended to inform new research and support regional ecosystem‐based management approaches.This manuscript is the result of follow‐up work stemming from a working group formed at a two‐day multidisciplinary and international workshop held at the Parker River National Wildlife Refuge, Massachusetts in May 2017, which convened 55 experts scientists, natural resource managers and conservation practitioners from 15 state, federal, academic and non‐governmental organizations with interest and expertise in Ammodytes ecology.

Moving black holes via singularity excision

We present a singularity excision algorithm appropriate for numerical simulations of black holes moving throughout the computational domain. The method is an extension of the excision procedure previously used to obtain stable simulations of single, non-moving black holes. The excision procedure also shares elements used in recent work to study the dynamics of a scalarfield in the background of a single, boosted black hole. The robustness of our excision method is tested with single black-hole evolutions using a coordinate system in which the coordinate location of the black hole, and thus the excision boundary, moves throughout the computational domain.Comment: 9 pages and 11 figure

Impact of densitized lapse slicings on evolutions of a wobbling black hole

We present long-term stable and second-order convergent evolutions of an excised wobbling black hole. Our results clearly demonstrate that the use of a densitized lapse function extends the lifetime of simulations dramatically. We also show the improvement in the stability of single static black holes when an algebraic densitized lapse condition is applied. In addition, we introduce a computationally inexpensive approach for tracking the location of the singularity suitable for mildly distorted black holes. The method is based on investigating the fall-off behavior and asymmetry of appropriate grid variables. This simple tracking method allows one to adjust the location of the excision region to follow the coordinate motion of the singularity.Comment: 10 pages, 8 figure

Sward type alters the relative abundance of members of the rumen microbial ecosystem in dairy cows

peer-reviewedThe performance of ruminant livestock has been shown to beneft from the enhanced nutritive value and herbage yield associated with clover incorporation in the grazing sward. However, little research to date has been conducted investigating the efects of mixed swards containing white clover on the composition of the rumen microbiome. In this study, the rumen microbial composition of late lactation dairy cows grazing perennial ryegrass only (PRG; n=20) or perennial ryegrass and white clover (WCPRG; n=19) swards, was characterised using 16S rRNA amplicon sequencing. PERMANOVA analysis indicated diet signifcantly altered the composition of the rumen microbiome (P=0.024). Subtle shifts in the relative abundance of 14 bacterial genera were apparent between diets, including an increased relative abundance of Lachnospira (0.04 vs. 0.23%) and Pseudobutyrivibrio (1.38 vs. 0.81%) in the WCPRG and PRG groups, respectively. The composition of the archaeal community was altered between dietary groups, with a minor increase in the relative abundance of Methanosphaera in the WCPRG observed. Results from this study highlight the potential for sward type to infuence the composition of the rumen microbial community

Reflections: Students\u27 Tribute to Stan Kuczaj (1950-2016)

On April 14th, 2016, Animal Behavior and Cognition lost its Editor-in-Chief. But the scientific community and the friends and colleagues of Stanley ‘Stan’ Kuczaj III lost so much more. As many know, Stan began his career in Developmental Psychology, making enormous contributions in the area of language development, but became best known for his many innovative contributions in the area of marine mammal behavior. Stan founded Animal Behavior and Cognition because he was deeply passionate about research with a broad range of topics concerning animal behavior, animal cognition, and animal welfare. He was equally passionate about the idea that science should be accessible to all, and that accessibility should not come at a financial burden to researchers. The current editorial team is committed to carrying on Stan’s vision for the journal, and we believe that its continuation will pay homage to Stan as a researcher, and as a leader within the scientific community. However, for the next few pages, we wish to pay special tribute to Stan as a mentor, as this role was perhaps the one that was most pivotal in defining who he was as a scientist, colleague, and friend. We take comfort in the fact that Stan’s memory will live on in the legacy of his mentees, many of whom became cherished friends and colleagues. Below you will find reflections from several of these former students who were given the difficult task of trying to summarize the most meaningful aspect of Stan’s influence on their personal and professional development. Although no few words could summarize the impact of someone as enigmatic as Stan, we hope that these reflections will contribute to a full and nuanced tribute to the man he was

Preliminary estimates of the abundance and fidelity of dolphins associating with a demersal trawl fishery

The incidental capture of wildlife in fishing gear presents a global conservation challenge. As a baseline to inform assessments of the impact of bycatch on bottlenose dolphins (Tursiops truncatus) interacting with an Australian trawl fishery, we conducted an aerial survey to estimate dolphin abundance across the fishery. Concurrently, we carried out boat-based dolphin photo-identification to assess short-term fidelity to foraging around trawlers, and used photographic and genetic data to infer longer-term fidelity to the fishery. We estimated abundance at approximate to 2,300 dolphins (95% CI = 1,247-4,214) over the ≈ 25,880-km2 fishery. Mark-recapture estimates yielded 226 (SE = 38.5) dolphins associating with one trawler and some individuals photographed up to seven times over 12 capture periods. Moreover, photographic and genetic re-sampling over three years confirmed that some individuals show longterm fidelity to trawler-associated foraging. Our study presents the first abundance estimate for any Australian pelagic dolphin community and documents individuals associating with trawlers over days, months and years. Without trend data or correction factors for dolphin availability, the impact of bycatch on this dolphin population's conservation status remains unknown. These results should be taken into account by management agencies assessing the impact of fisheries-related mortality on this protected species.Publisher PDFPeer reviewe
