    "Original authors: Joe Parcell, Ray Massey and David Reinbott"--Page 4."Producers expand their base of operations by purchasing or renting additional land. Some producers may prefer leasing farmland as opposed to purchasing due to a lack of capital, to reserve capital for other purposes, a shortage of land for sale, or the personal belief that leasing farmland is more profitable than owning it. The three most common types of farmland lease agreements in Missouri are cash rentals, flexible-cash leases and crop-share leases. This guide presents information on crop-share leases."--First page.Revised by Ben Brown (Senior Research Associate, Agriculture Business and Policy Extension), Drew Kientzy (Student Research Assistant).

    The SARS-CoV-2 Alpha variant was associated with increased clinical severity of COVID-19 in Scotland: A genomics-based retrospective cohort analysis

    Objectives The SARS-CoV-2 Alpha variant was associated with increased transmission relative to other variants present at the time of its emergence and several studies have shown an association between Alpha variant infection and increased hospitalisation and 28-day mortality. However, none have addressed the impact on maximum severity of illness in the general population classified by the level of respiratory support required, or death. We aimed to do this. Methods In this retrospective multi-centre clinical cohort sub-study of the COG-UK consortium, 1475 samples from Scottish hospitalised and community cases collected between 1st November 2020 and 30th January 2021 were sequenced. We matched sequence data to clinical outcomes as the Alpha variant became dominant in Scotland and modelled the association between Alpha variant infection and severe disease using a 4-point scale of maximum severity by 28 days: 1. no respiratory support, 2. supplemental oxygen, 3. ventilation and 4. death. Results Our cumulative generalised linear mixed model analyses found evidence (cumulative odds ratio: 1.40, 95% CI: 1.02, 1.93) of a positive association between increased clinical severity and lineage (Alpha variant versus pre-Alpha variants). Conclusions The Alpha variant was associated with more severe clinical disease in the Scottish population than co-circulating lineages

    Objectives: To determine how the intrinsic severity of successively dominant SARS-CoV-2 variants changed over the course of the pandemic. Methods: A retrospective cohort analysis in the NHS Greater Glasgow and Clyde (NHS GGC) Health Board. All sequenced non-nosocomial adult COVID-19 cases in NHS GGC with relevant SARS-CoV-2 lineages (B.1.177/Alpha, Alpha/Delta, AY.4.2 Delta/non-AY.4.2 Delta, non-AY.4.2 Delta/Omicron, and BA.1 Omicron/BA.2 Omicron) during analysis periods were included. Outcome measures were hospital admission, ICU admission, or death within 28 days of positive COVID-19 test. We report the cumulative odds ratio; the ratio of the odds that an individual experiences a severity event of a given level vs all lower severity levels for the resident and the replacement variant after adjustment. Results: After adjustment for covariates, the cumulative odds ratio was 1.51 (95% CI: 1.08–2.11) for Alpha versus B.1.177, 2.09 (95% CI: 1.42–3.08) for Delta versus Alpha, 0.99 (95% CI: 0.76–1.27) for AY.4.2 Delta versus non-AY.4.2 Delta, 0.49 (95% CI: 0.22–1.06) for Omicron versus non-AY.4.2 Delta, and 0.86 (95% CI: 0.68–1.09) for BA.2 Omicron versus BA.1 Omicron. Conclusions: The direction of change in intrinsic severity between successively emerging SARS-CoV-2 variants was inconsistent, reminding us that the intrinsic severity of future SARS-CoV-2 variants remains uncertain
