    Abstract Organic-rich sediments (sapropels) deposited in the Mediterranean are presumed to have formed during periods of increased productivity, and/or deep water oxygen depletion, possibly including the development of sulfidic conditions (euxinia). Geochemical redox proxies (Re, Mo, Mo isotopes, V, Fe/Al, and multiple S isotopes) in 8 sapropels from the Pleistocene confirm water column euxinic conditions of varying intensity during sapropel deposition. These same proxies indicate an oxic origin for hemipelagic sediments deposited between sapropel-forming episodes.
    In one intensively sampled sapropel, deposited between 1.450 and 1.458 Ma, changing concentrations of organic carbon, Ba, Re, Mo, V, and Fe/Al track one another closely, reflecting coupling between water column euxinia and biological productivity. Multiple S isotope data from this sapropel suggest that the redox interface where oxidative sulfur cycling occurred was present in the sediments during hemipelagic sedimentation, but moved into the water column during sapropel deposition.
    Molybdenum isotopes of these 8 sapropels encompass a range of values (d98Mo = +0.2 to +1.7), but are all 98Mo-depleted relative to seawater (d98Mo = +2.3 per mil), suggesting that quantitative removal of Mo did not occur. This finding contrasts with modern Black Sea sediments. In general, Re/Mo ratios in sapropels are greater than in modern seawater, implying that the water column was not sufficiently sulfidic during sapropel-forming episodes to induce complete removal of both these elements. Surprisingly, the heaviest d98Mo values are found within hemipelagic sediments. Very few of the hemipelagic samples preserve the negative d98Mo values commonly associated with modern oxic marine sediments. Many of the hemipelagic samples also contained higher concentrations of Re and Mo than are common in oxic sediments. These features may be attributable to diffusion from the sapropels of a 98Mo-enriched component into the hemipelagic sediments.

    Abstract The most common cause of heart failure in the United States is ischemic left heart disease; accordingly, a vast amount of work has been done to elucidate the molecular mechanisms underlying pathologies of the left ventricle (LV) as a general model of heart failure. Until recently, little attention has been paid to the right ventricle (RV) and it has commonly been thought that the mechanical and biochemical properties of the RV are similar to those of the LV. However, therapies used to treat LV failure often fail to improve ventricular function in RV failure underscoring, the need to better understand the unique physiologic and pathophysiologic properties of the RV. Importantly, hemodynamic stresses (such as pressure overload) often underlie right heart failure further differentiating RV failure as unique from LV failure. There are significant structural, mechanical, and biochemical properties distinctive to the RV that influences its function and it is likely that adaptations of the RV occur uniquely across the lifespan. We have previously reviewed the adult RV compared to the LV but there is little known about differences in the pediatric or aged RV. Accordingly, in this mini-review, we will examine the subtle distinctions between the RV and LV that are maintained physiologically across the lifespan and will highlight significant knowledge gaps in our understanding of pediatric and aging RV. Consideration of how RV function is altered in different disease states in an age-specific manner may enable us to define RV function in health and importantly, in response to pathology.

    Abstract Throughout the COVID-19 pandemic, the American College Health Association (ACHA) has partnered with CommunicateHealth (CH) to develop COVID-19 mitigation resources for colleges and universities. In 2021, the CH team conducted a series of applied research activities to gain a nuanced understanding of factors that shape perceptions of risk and drive vaccine hesitancy among campus audiences-especially college students who are emerging adults (approximately ages 18 to 22). Based on our findings, CH and ACHA identified key traits of vaccine-hesitant college students and implications for future vaccine communication campaigns. First, vaccine-hesitant students are more likely to ask "why" and "how" questions such as "Why do I need to get vaccinated?" and "How was the vaccine developed and tested?". Secondly, these students want to have open, authentic dialogue rather than simply accepting health recommendations from a trusted source. Finally, the CH team noted that vaccine-hesitant students were not highly motivated by their own personal risk of getting sick from COVID-19; concern about spreading COVID-19 to others was a much stronger motivating factor. Leveraging these insights, CH and ACHA developed strategies to apply health literacy principles to reach vaccine-hesitant college students with the right information at the right time-and to leverage relevant motivators and overcome barriers to vaccination. By implementing these strategies, CH and ACHA developed clear and empowering educational materials about COVID-19 vaccination tailored to the unique information needs of vaccine-hesitant students.

    Abstract This study evaluated the effect of biodiesel as a co-solvent with the wood preservative creosote to reduce the amount of hydrocarbon-based carrier utilized. Small blocks of wood were treated at a pilot scale using three different creosote concentrations. The diluent used was a blend of 80% soybean biodiesel and 20% petroleum diesel. The efficacy of creosote was tested against brown rot and white rot fungi. The results of the wood-block test and agar test suggested that there was no significant effect of biodiesel on the efficacy of creosote as a wood preservative. As creosote-treated wood is commonly used for railway ties, its potential impact on the surrounding environment was also assessed by studying the leaching behavior of creosote–biodiesel–diesel blend treated railway ties. Rainfall simulators were used to imitate an exposure of treated wood to a significant amount of rainfall. Wood core drilled from the exposed railway ties and leaching water samples were analyzed for the levels of polycyclic aromatic hydrocarbons (PAHs) and total petroleum hydrocarbons (TPHs). Overall, this study demonstrated that the diluent containing biodiesel had no negative effect on the performance of creosote as a wood preservative and towards the natural environment.

    Abstract Background: In April 2020, the diagnostic criteria for gestational diabetes mellitus (GDM) changed in Queensland, with the goal of reducing exposure of pregnant women to COVID-19.
    Methods: A retrospective clinical audit was conducted at a regional hospital to compare the incidence of GDM, and specific maternal and neonatal outcomes four months before and after the change in guidelines was implemented.
    Results: Less than 50% of diagnostic tests were performed according to new guidelines. There was a non-significant increase in the incidence of GDM (13.3% to 15.3%), and pharmacological treatments. Instrumental deliveries (
    Conclusions: Despite the change in guidelines, there was a non-significant increase in the incidence of diagnosis of gestational diabetes.
