Land application of biosolids to pastures confers multiple agronomic and environmental benefits, particularly in coarse-textured soils with low nutrient and organic matter levels. However, concerns over potential water quality have led to more stringent regulations that will limit beneficial reuse of biosolids in Florida. This 3-year field study evaluated the impacts of biosolids application strategies on N and P leaching losses, and soil P availability in an established bahiagrass (Paspalum notatum Flueggé) pasture.

Cardiovascular disease and cancer constitute the most prevalent illnesses worldwide. Cancer patients show an increased risk of coronary artery disease not only due to shared cardiovascular risk factors, a pro-inflammatory and prothrombotic state induced by cancer itself, the cardiovascular toxicity of cancer therapy, or rarely, due to extrinsic compression of a coronary artery by the primary tumor or a metastatic lesion. Here, we present the case of a 59-year-old man with squamous cell carcinoma of the lung presented with asymptomatic diffuse ST segment depression and troponin T increase.

Objective: Pain is experienced by most patients with cancer and opioids are a cornerstone of management. Our objectives were (1) to identify patterns or trajectories of long-term opioid therapy (LTOT) and their correlates among patients with and without cancer and (2) to assess the association between trajectories and risk for opioid overdose, considering the potential moderating role of cancer.

Methods And Analysis: We conducted a retrospective cohort study among individuals in the US Veterans Health Administration (VHA) database with incident LTOT with and without cancer (N=44,351; N=285,772, respectively) between 2010-2017.

Prescribed fire is a common management practice used to manipulate rangeland plant productivity and composition. Although the nutritive value of most herbaceous plant species is considered poor for grazing animals, native rangelands in Florida are an important source of forage for livestock, especially during the winter months, when the productivity of cultivated perennial warm-season pastures is limited. This study evaluated the effects of prescribed fire on methanogenic potential and nutritive value of selected native rangeland plant species.

Despite evidence suggesting that biochar can retain nutrients, particularly nitrogen (N), and reduce the risks of transport, research on the co-application of biochar with organic and inorganic fertilizer sources is limited. Three laboratory studies (herein referred to as static incubation, column leaching, and batch sorption) were conducted to evaluate the impacts of two biochar materials (pine and grass biochar generated at temperatures of 800 and 400°C, respectively) on N and carbon (C) dynamics in soils amended with different N sources (ammonium nitrate, Class B, and Class AA biosolids). Nitrogen sources were applied at an equivalent rate of 180 kg N ha while biochar was applied at a 1% (w/w) rate.
