- Abstract
Background: In July 2020, a COVID-19 outbreak was recognised in the geriatric wards at a subacute campus of the Royal Melbourne Hospital affecting patients and staff. Patients were also admitted to this site after diagnosis in residential care. Aims: To describe the early symptoms and the outcomes of COVID-19 in older adults. Methods: Patients diagnosed with COVID-19 at the facility in July or August 2020 were identified and their medical records were examined to identify symptoms present before and after their diagnosis and to determine their outcomes. Results: Overall, 106 patients were identified as having COVID-19, with median age of 84.3 years (range 41–104 years); 64 were diagnosed as hospital inpatients after a median length of stay of 49 days, 31 were transferred from residential aged care facilities with a known diagnosis and 11 were diagnosed after discharge. There were 95 patients included in an analysis of symptom type and timing onset. Overall, 61 (64.2%) were asymptomatic at the time of diagnosis of COVID-19, having been diagnosed through screening initiated on site. Of these, 88.6% developed symptoms of COVID-19 within 14 days. The most common initial symptom type was respiratory, but there was wide variation in presentation, including fever, gastrointestinal and neurological symptoms, many initially not recognised as being due to COVID-19. Of 104 patients, 32 died within 30 days of diagnosis. Conclusions: COVID-19 diagnosis is challenging due to the variance in symptoms. In the context of an outbreak, asymptomatic screening can identify affected patients early in the disease course.

- Abstract
Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, and biomass. We found that local species richness and abundance typically peaked at higher latitudes, displaying patterns opposite to those observed in aboveground organisms. However, high species dissimilarity across tropical locations may cause diversity across the entirety of the tropics to be higher than elsewhere. Climate variables were found to be more important in shaping earthworm communities than soil properties or habitat cover. These findings suggest that climate change may have serious implications for earthworm communities and for the functions they provide., Unión Europea. Horizonte 2020, Unión Europea.

The soil food web has been referred to as a 'black box', a 'poor man's tropical rainforest' and an 'enigma', due to its opacity, diversity and the limited insight into feeding specificity. Here we investigate the flow of C and N through the soil food web as a way to gain understanding of the feeding interactions occurring. A bacterium, Pseudomonas lurida, was introduced to soil cores from two different habitats, a grassland and a woodland with the same soil type, enriched to 99 atom% in C-13 and N-15, to trace the flow of bacterial C and N through the soil food web. Throughout the experiment the soil remained enriched in C-13 and N-15. Almost all the invertebrates tested gained C and N enrichment indicative of the labelled bacteria, implying that bacterial feeding is a common mechanism within the soil. Only three groups were significantly enriched in both C-13 and N-15 in both habitats. These were Collembola (Entomobryomorpha), Acari (Oribatida), and Nematoda, indicating that these organisms are consuming the most bacteria within both systems. When the invertebrates were grouped into hypothesised trophic levels, those considered secondary decomposers were gaining the most enrichment across all invertebrates tested. This enrichment was also high in the micro-predators within the soil, implying that their main food source was the secondary decomposers, particularly the Collembola. Using an enriched bacterium to track the trophic transfer between organisms within the soil food web is a novel way of empirically showing that interactions are occurring, which normally cannot be seen.

- Abstract
Contact with nature can contribute to health and wellbeing, but knowledge gaps persist regarding the environmental characteristics that promote these benefits. Understanding and maximising these benefits is particularly important in urban areas, where opportunities for such contact is limited. At the same time, we are facing climate and ecological crises which require policy and practice to support ecosystem functioning. Policies are increasingly being oriented towards delivering benefits for people and nature simultaneously. However, different disciplinary understandings of environments and environmental quality present challenges to this agenda. This paper highlights key knowledge gaps concerning linkages between nature and health. It then describes two perspectives on environmental quality, based respectively in environmental sciences and social sciences. It argues that understanding the linkages between these perspectives is vital to enable urban environments to be planned, designed and managed for the benefit of both environmental functioning and human health. Finally, it identifies key challenges and priorities for integrating these different disciplinary perspectives., (Copyright © 2024 The Authors. Published by Elsevier Ltd.. All rights reserved.)

21. Should farmers apply fertilizer according to when their daffodils are in flower? Utilizing a "farmer-science" approach to understanding the impact of soil temperature on spring N fertilizer application in Wales.

Crotty F, McCalman H, Powell H, Buckingham S, and Marley C
- Abstract
Perennial ryegrass starts growing when soil temperatures reach 5.5°C for five consecutive days; applying N fertilizer before this risks environmental losses. To test whether daffodil flowering signified when to apply N fertilizer, farmers volunteered to take part in a citizen science study. The PROSOIL project used a "citizen science", participatory approach to create farmer-informed science, aiming to increase awareness of the importance of soil health. In 2014, over 300 farmers completed a " How do you manage your soil " survey. The survey included a question on the use of daffodils ( Narcissus spp.) to indicate the best time to apply the first nitrogen fertilizer of the season, based on anecdotal feedback from farmers involved in the PROSOIL project. The survey recorded 7% of farmers based their first fertilizer application on when daffodils flowered. To increase farmer awareness of soil temperatures, we provided them with soil thermometers, held workshops and hosted interactive stands at agricultural events in 2014. In autumn 2014, farmers planted daffodil bulbs of the same variety, across Wales, and monitored soil temperatures. Farmers returned postcards once their daffodils were in flower, noting the soil temperature. An assessment of whether daffodil flowering date could indicate when to apply N fertilizer was made. Overall, in spring 2015, daffodils flowered when soil temperature was 6.4(±0.35)°C, suggesting daffodil flowering date is a more reliable indicator for fertilizer application, than first hypothesized. Findings show a scientific validation of local knowledge, regarding the use of daffodils to indicate the "not-before" date for the first N fertilizer application.

Crotty F and Sheehan J
- Abstract
Objectives: To establish the prevalence of postnatal depression using standardised methods of diagnosis and to evaluate early detection of postnatal depression., Methods: Prospective cohort study. Prevalence established using two-step screening with EPDS and semi-structured clinical interview for ICD-10 diagnosis. EPDS recorded at day three-five postnatal evaluated as predictor of depression at week six postnatal., Results: Prevalence established at 14.4%. EPDS recorded at day three-five postnatal when combined with past history of depression was a predictor of depression occurring at week six postnatal., Conclusions: We found a similar prevalence of postnatal depression in this Irish sample to other international prevalence studies. There are implications for hospital based screening to identify those at risk of developing a postnatal depression.
