How experiences of weight stigma impact higher-weight women during their maternity care: A meta-ethnography.

Aim: The aim of this review was to explore the experiences of pregnant women and birthing people with higher weight bodies, to understand the extent to which weight stigma impacted their maternity care.

Methods: We performed a systematic search of seven databases (CINAHL plus, Medline, Social Sciences Full Text [SSFT], International Bibliography of Social Sciences [IBSS], PsychINFO, Maternity and Infant Care [MIC], NIHR Journals Library, EThOS) using the Setting, Perspective, Intervention, Comparison, Evaluation (SPICE) framework search strategy and pre-defined inclusion and exclusion criteria. Included studies underwent a critical appraisal and data richness assessment.

Factors influencing mercury exposure in Arctic-breeding shorebirds.

Mercury (Hg) pollution remains a concern to Arctic ecosystems, due to long-range transport from southern industrial regions and melting permafrost and glaciers. The objective of this study was to identify intrinsic, extrinsic, and temporal factors influencing Hg concentrations in Arctic-breeding shorebirds and highlight regions and species at greatest risk of Hg exposure. We analyzed 1094 blood and 1384 feather samples from 12 shorebird species breeding at nine sites across the North American Arctic during 2012 and 2013.

Composition and Drivers of Gut Microbial Communities in Arctic-Breeding Shorebirds.

Gut microbiota can have important effects on host health, but explanatory factors and pathways that determine gut microbial composition can differ among host lineages. In mammals, host phylogeny is one of the main drivers of gut microbiota, a result of vertical transfer of microbiota during birth. In birds, it is less clear what the drivers might be, but both phylogeny and environmental factors may play a role.

Phenological mismatch in Arctic-breeding shorebirds: Impact of snowmelt and unpredictable weather conditions on food availability and chick growth.

The ecological consequences of climate change have been recognized in numerous species, with perhaps phenology being the most well-documented change. Phenological changes may have negative consequences when organisms within different trophic levels respond to environmental changes at different rates, potentially leading to phenological mismatches between predators and their prey. This may be especially apparent in the Arctic, which has been affected more by climate change than other regions, resulting in earlier, warmer, and longer summers.

The evidence base regarding the experiences of and attitudes to preimplantation genetic diagnosis in prospective parents.

Baackground: Preimplantation genetic diagnosis was developed as an alternative to prenatal diagnosis for couples with a family history of genetic disease. After in vitro fertilization, the embryos can be analysed to ensure that only healthy embryos are transferred to the uterus. Past studies have suggested that couples who wish to avoid having a child with an inherited genetic condition look favourably on preimplantation genetic diagnosis as it prevents the need for termination of pregnancy following prenatal diagnosis of an affected fetus.

Nest box-deployed bait for delivering oral vaccines to white-footed mice.

Although a wide range of interventions are available for use in reducing the public health burden of Lyme disease, additional tools are needed. Vaccinating mouse reservoirs may reduce the prevalence of spirochetal infection due to the powerful vector and reservoir competence-modulating effects of anti-outer surface protein A (OspA) antibody. A delivery system for an oral immunogen would be required for field trials of any candidate vaccine.

Prevalence of Ehrlichia muris in Wisconsin Deer Ticks Collected During the Mid 1990s.

Human ehrlichiosis is due to infection by tick transmitted bacteria of the genus Ehrlichia. Based on a hypothesis for the biogeography of deer tick transmitted infections, we undertook a focused search for the Eurasian E. muris in North American deer ticks.

Rickettsia rickettsii (Rickettsiales: Rickettsiaceae) in Amblyomma americanum (Acari: Ixodidae) from Kansas.

The role of lone star ticks as vectors for Rocky Mountain spotted fever (RMSF) remains poorly described. We compared the entomological inoculation rates (EIRs) for Rickettsia spp. for representative sites in Missouri and Kansas, states that frequently report RMSF each year.

Photochemical reactions of [CH2(eta5-C5H4)2][Rh(C2H4)2]2 with silanes: evidence for Si-C and C-H activation pathways.

Photochemical reaction of [CH2(eta5-C5H4)2][Rh(C2H4)2]2 1 with dmso led to the stepwise formation of [CH2(eta5-C5H4)2][Rh(C2H4)2][Rh(C2H4)(dmso)] 2a and [CH2(eta5-C5H4)2][Rh(C2H4)(dmso)]2 2b. Photolysis of 1 with vinyltrimethylsilane ultimately yields three isomeric products of [CH2(eta5-C5H4)2][Rh(CH2=CHSiMe3)2]2, 3a, 3b and 3c which are differentiated by the relative orientations of the vinylsilane. When this reaction is undertaken in d6-benzene, H/D exchange between the solvent and the alpha-proton of the vinylsilane is revealed.

NMR characterisation of unstable solvent and dihydride complexes generated at low temperature by in-situ UV irradiation.

Low temperature in-situ UV irradiation of toluene solutions containing bis(alkene)rhodium complexes and parahydrogen in conjunction with NMR monitoring enables the characterisation of unstable eta 2-solvent complexes and dihydrogen activation products.
