BACKGROUND: The primary aim of this study was to assess the outcome of elderly intensive care unit (ICU) patients treated during the spring and autumn COVID-19 surges in Europe.METHODS: This was a prospective European observational study (the COVIP study) in ICU patients aged 70 years and older admitted with COVID-19 disease from March to December 2020 to 159 ICUs in 14 European countries. An electronic database was used to register a number of parameters including: SOFA score, Clinical Frailty Scale, co-morbidities, usual ICU procedures and survival at 90 days. The study was registered at ClinicalTrials.gov (NCT04321265).RESULTS: In total, 2625 patients were included, 1327 from the first and 1298 from the second surge. Median age was 74 and 75 years in surge 1 and 2, respectively. SOFA score was higher in the first surge (median 6 versus 5, p < 0.0001). The PaO2/FiO2 ratio at admission was higher during surge 1, and more patients received invasive mechanical ventilation (78% versus 68%, p < 0.0001). During the first 15 days of treatment, survival was similar during the first and the second surge. Survival was lower in the second surge after day 15 and differed after 30 days (57% vs 50%) as well as after 90 days (51% vs 40%).CONCLUSION: An unexpected, but significant, decrease in 30-day and 90-day survival was observed during the second surge in our cohort of elderly ICU patients. The reason for this is unclear. Our main concern is whether the widespread changes in practice and treatment of COVID-19 between the two surges have contributed to this increased mortality in elderly patients. Further studies are urgently warranted to provide more evidence for current practice in elderly patients.TRIAL REGISTRATION NUMBER: NCT04321265 , registered March 19th, 2020.

Even though mango productivity in Ethiopia is low due to moisture stress, there is no report on how such constraint could alleviate using Cocoon water-saving technology. Cocoon is small water reservoir technology which uses for plant growth in dry season. The objectives of this study were to introduce and evaluate effectiveness of water-saving techniques on mango seedlings survival and growth in Mihitsab-Azmati watershed, northern Ethiopia. In this experiment, five treatments of water-saving techniques with mango seedlings were evaluated. These were: Cocoon sprayed by tricel (T1), Cocoon painted by used engine oil (T2), Cocoon without tricel and oil (T3), manually irrigated seedlings (T4) and mango seedlings planted during rainy season (T5). The survival and growth performance of mango seedlings were recorded at six months and one-year after transplanting. Data on plant survival, height, number of leaves per plant, shoot length, stem diameter and crown width were subjected to analysis of variance and t-test. There were significant differences in the treatment effects on mango seedlings transplanted survival, plant height, number of leaves per plant, shoot length, stem diameter and crown width measured at six months and one-year after transplanting. The lowest survival rate (20 %) was found during both data collection time in T5. Six months after transplanting, the highest growth parameters were measured from T1 whereas the lowest was from T5. However, one-year after transplanting, the highest growth parameters were measured from T3. Plant heights increments between the two measurement periods for T3, T2, T1, T4 and T5 were 45.1, 38.5, 24.8, 9.8 and 7.0 cm, respectively; indicating that T3 performed better than the other treatments. The t-test on mean differences between the same growth parameter measured at 12 and six months after transplanting also showed significant differences. The Cocoon water-saving technology was superior in improving mango seedlings survival and growth in the study area. This study generalized that Cocoon seems promising, sustainable and highly scalable with mango seedlings at large-scale in the study area conditions. However, this technology should not be assumed to perform uniformly well in all environmental conditions and with all tree species before demonstrated on a pilot study.

In the literature about web survey methodology, significant e orts have been made to understand the role of time-invariant factors (e.g. gender, education and marital status) in (non-)response mechanisms. Time-invariant factors alone, however, cannot account for most variations in (non-)responses, especially fluctuations of response rates over time. This observation inspires us to investigate the counterpart of time-invariant factors, namely time-varying factors and the potential role they play in web survey (non-)response. Specifically, we study the effects of time, weather and societal trends (derived from Google Trends data) on the daily (non-)response patterns of the 2016 and 2017 Dutch Health Surveys. Using discrete-time survival analysis, we find, among others, that weekends, holidays, pleasant weather, disease outbreaks and terrorism salience are associated with fewer responses. Furthermore, we show that using these variables alone achieves satisfactory prediction accuracy of both daily and cumulative response rates when the trained model is applied to future unseen data. This approach has the further benefit of requiring only non-personal contextual information and thus involving no privacy issues. We discuss the implications of the study for survey research and data collection.
Many Caribbean reefs have shifted from coral-dominated to algal-dominated ecosystems. The high algae cover reduces coral recruitment, making the reef unable to recover from other disturbances and resulting in flatter reefs with lower biodiversity. One of the reasons for the proliferation of algae is a mass die-off of the herbivorous sea urchin Diadema antillarum in the early 1980s. Natural recovery of Diadema populations is slow to non-existent, making active restoration of this important grazer a top priority in Caribbean coral reef management, especially since Diadema densities were reduced by another mass mortality event in 2022. The marine park organizations of Saba and St. Eustatius want to restore Diadema populations by restocking cultured individuals. However, important knowledge gaps need to be addressed before large numbers of Diadema can be restocked on the reef. Current culture methods can only produce a limited number of competent larvae. In addition, only 8% of the settlers survive and after restocking, survival on the reef is low as well. In the RAAK PRO Diadema II project, the bottlenecks in Diadema culture will be addressed by comparing larval survival across multiple culture methods and investigating the relation between larval size and post-settlement survival. Growing-out juveniles at sea is likely to help prepare them for life in the wild, while restocking at an optimal size might also increase survival. Finally, a thorough restocking site selection based on high shelter availability and settlement rates will increase the long-term Diadema densities. The acquired knowledge and developed practices will be verified in a larger scale restocking experiment involving at least 5000 Diadema urchins. By restoring Diadema populations through restocking, macroalgae will be more intensively removed and corals will have a chance to settle and to survive, increasing the ability of the reef to cope with other stressors.
In this project on volunteering in LTH organisation we focus on three aims:1. To explain why organisations in different LTH sectors and regions had, have or need volunteers, how they interact with these volunteers, and the consequences (benefits and challenges) of volunteerism for these organisations.2. To determine how to find the right balance between paid and unpaid staff within the same organisation, considering the LTH sector and region they belong to, in order to create a healthy ecosystem within it (bearing in mind that no organisation can have both volunteers and paid staff do the same job - see above).3. To understand the perspectives, motives and expectations of why people (decide to) volunteer, how they interact with the organisation (management, paid staff) during volunteering, in order to interest them, recruit them, make use of them and retain them. In addition, it is also our aim to explain the benefits and challenges for people to volunteer.In this study, we will use an integrated approach, which implies that we aren’t only interested in the people- or organisation-side of volunteering (actor-side). We will also focus on the interactions between volunteers, paid staff and organisation during volunteering (core of the practice) in a certain LTH organisation, sector and region in the Netherlands (context-side). Studying volunteering in its specific contexts (organisation, sector, region) using an integrated practice approach, hasn’t been done before. In addition, as more and more LTH organisations in the Netherlands rely on volunteers (for their survival), either for economic, social or community (mienskip) reasons (context-related conditions), there is a need for a better understanding of volunteering (as indicated by aim 1-3). Finally, as not much literature has been based on Dutch studies about volunteering and the recruitment and retention of volunteers, this project will fill this gap.Besides the aims as outlined before, a more specific goal of this project is to provide recommendations for a sustainable business model for organisations to embrace volunteerism without affecting the structure of employees. In close cooperation with different LTH organisations, we will develop interventions as policy making instruments (and therefore also for the whole region where they are located). Furthermore, this research will contribute to industry, research (see also below), education (idem) and society. Our ultimate goal is to foster the wellbeing of the volunteers, paid staff and organisations and overall to contribute to social sustainability within The Netherlands.The above-mentioned aims and conceptual model lead to the following research question: How can volunteering in the LTH sectors in Dutch regions be shaped in a sustainable way for both volunteers as well as organisations?In line with what we discussed earlier, this also means contributing to a more stable labour market in hospitality, leisure and tourism in which voluntary work is recognised as an important and indispensable component of a healthy labour ecosystem.The approach we intend to adopt is a qualitative one based on narrative inquiry. While in the literature a quantitative approach using surveys to gather data is mostly used in understanding volunteerism and in measuring motives, we will observe and connect with the volunteers’ work in each sector/case identified and collect and analyse their individual stories. In addition, and in line with our integrated approach, we will investigate how the LTH organisations connected to these cases view the role, value and future of volunteerism.Societal IssueOur insights into volunteers’ work in different sectors will improve their quality of work by revealing drivers of their satisfaction, turnover, motivation, and passion. Managers can use these insights to train and retain volunteers as an integral part of not only their events, but the broader community. It is well-known that robust volunteering programmes are a cornerstone of contemporary social cohesion, and our findings will show how storytelling can strengthen these processes.Benefit to societyThis project will contribute in three ways to the LTH sector. The three outcomes of this study are first around a better understanding of what meaningful volunteering is, second, around the value of volunteers to LTH organisations, and, thirdly, about the value of such activities to Dutch society.The project will provide practical advice to LTH organisations on which interventions to use and in which contexts. This tangible output might take the form of a report, guide(s) mentioned above, and/or another instrument that suits the needs of managers and volunteers. The instrument(s) selected by LTH organisations and volunteers will help to disseminate best practices as well as to highlight the potential of volunteers and volunteering to wider society, other organisations and to current and potential volunteers. By following the steps in or using these instruments, we believe volunteer organisations will be better able to profile themselves and to recruit and retain volunteers.The present study will bring innovation in the field by generating new narratives on volunteerism, and by designing an engaging and appealing path for volunteers to join organisations. At the same time, it will design a structure for organisations to work with volunteers in a sustainable way.Consortium partners: Rodney Westerlaken, Geesje Duursma (both NHL Stenden, Leeuwarden)
