Engaging Nurses in Effective Cost of Care Conversations to Address Cancer-Related Financial Toxicity: Results from an Exploratory Survey
Full text linkFew evidence-based trainings exist on how to equip healthcare providers, particularly nurses, with the skills to engage in cost of care conversations with patients/caregivers to mitigate the impact of cancer-related financial toxicity. This study evaluated a pilot training developed in collaboration with Triage Cancer® to prepare oncology nurses to identify and assist patients/caregivers facing financial and/or legal barriers to care. Ten pediatric oncology nurses completed the training and pre/post-surveys on behaviors related to financial and legal need screening, frequency and comfort level of answering questions, knowledge, and behavior changes, along with training evaluation questions. At baseline, six nurses reported never screening for financial needs and nine for legal needs. Following the training, seven nurses stated they were likely to screen for financial/legal needs. At six months post-training, nurses had referred 85 patients/caregivers to financial/legal navigation services. Comfort levels in answering financial/legal questions increased by 6.5 points and knowledge scores increased by 1.7 points post-training. Most nurses recommended this training to other healthcare providers who work with patients with cancer and their caregivers. This study highlights the importance of providing oncology nurses with resources to engage in cost of care conversations and oncology financial legal navigation programs to mitigate the impact of cancer-related financial toxicity
Agricultural Behaviour of LabLab purpureus Cv. Rongai Under Cuban Conditions
Full text linkProduction strategy of livestock in Cuba is based upon the utilization of swards as the main feeding source. Nevertheless, the climatical conditions that exist in certain period of the year lead to a seasonal productive unbalance due to the decreasing sequence of rainfall. Several alternatives have been adopted against this situation and one of them is the utilization of temporary cultivars. Taking into consideration the previous situation, the possibility of spreading Lablab purpureus, the suitable growth that it presents under temperatures among 18-30 °C (Duke, 1983), rainfall among 200-2500 mm (National Academy of Science, 1979) and its seed production from I to 2,6 t/ha (Wood, 1981) the following studies were made in order to estimate its agricultural behaviour under Cuban conditions
Seed Yield, Fodder Yield and Persistence in White Clover cvs of Different Origins. Results of Trials Conducted at Lodi (Irrigated PO Valley)
Full text linkWhite clover is the most important pasture legume in many EEC countries (white clover-ryegrass pasture system) and a good component of permanent and rotated polyphytic meadows in North Italy (irrigated Po Valley where the Ladino subspecies developed through self selection). The main characteristics of the species are N2 fixation and high nutritional value (quality). Therefore, white clover seed usage in the EEC is expected to still be important in the next decades. A number of performing varieties have recently been developed by EEC Research Institutes. An assessment of their seed production potential is necessary in view of self-sufficiency and consequent reduction of imported seed of poorly adapted cvs from overseas to W. Europe. Studies on white clover seed production have been carried out at Lodi in the past decades (Haussmann et al., 1949-1972; Haussmann, 1957). The participation to an European Research Group concerned with the above species is the most recent development in the theme (A.A., 1984; Marshall et al., 1987). The main results of the co-ordinated experiments, carried out at Lodi under the Plant Productivity Co-ordinated Trials Programme during the period 1982-1987, are briefly reported in this paper
Effects of Level and Source Nitrogen Fertilzier on the Pure Seed Yield of Setaria sphacelata cv. Narok in Yunnan Province, Southern China
Full text linkSetaria sphacelata is a widely sown pasture grass in the tropics and sub-tropics (Hacker and Jones, 1969). Its use is limited by low seed yields (10-80 kg/ha/crop) and the cold tolerant cv. Narok gives less seed than other cultivars (Bahnisch and Humphreys, 1977). In Queensland Setaria generally produces two crops a year with irrigation, but the seed yields are some of the lowest of any commercial species traded (Humphreys and Riveros, 1986). The objet of the present experimental work was to determine the optimum level of nitrogen and its time of application for maximum profit, and to study the seed yield components which were considered to be influenced by the rainfall pattern
Problems Associated with Evaluation of Disease of Perennial Pasture Plants - Some Recommendations
Full text linkMost of the existing pasture disease evaluation methodology has been developed for temperate grass and legume monocultures. Many techniques have been derived from annual crops with little modification and limited research has been done on perennial grass-legume pastures. Perennial pastures are heterogenous communities of various species of many ages supporting continuous pathogen associations. Because of temporal and spatial variation, diseases are difficult to evaluate and techniques are largely inadequate
Diachorella Leaf Spot of Prairie Milkvetch in Loess Plateau, China
Full text linkPrairie Milkvetch (Astragalus adsurgens), an acclimatized good sand binder, soil and water conservation legume forage plant, cultivated widely in the arid and semi-arid districts of North China, is especially suitable for the Loess Plateau, China. Unfortunately in the mid Inner Mongolia, North Shaanxi Province and the eastern part of Gansu Province, it is often infected seriously with Diachorella leaf spot (Diachorella lathyri Fckl.). The disease primarily affects leaves, but sometimes attacks petioles and stems. On infected leaflets first appear small black spots. As the spots increase, whole leaflet is blackened. Heavy infections kill leaflets and cause severe defoliation, and infected stems may die. The Diachorella species causing the leaf spot on Prairie Milkvetch is Diachorella lathyri Fckl. and it is a new record in China. The Diachorella leaf spot is also found in the natural population of Prairie Milkvetch in the same areas. Therefore, the origin of pathogen may be the wild Prairie Milkvetch plants. In order to extend cultivation of the Prairie Milkvetch crops in the above mentioned districts, it is necessary to carry out a study and research as well as prophylactic work on the Diachorella leaf spot. So, we started a preliminary investigation and study on this disease in 1987
Spanish Subclover Ecotypes: Evaluation under Grazing
Full text linkThe introduction of australian subclover varieties in the mediterranean environments of Europe has had irregular results (Olea et al., 1985). For this reason, important projects in selection and genetic improvement of subclover varieties adapted to these environments are carried out in Spain, Portugal and Sardinia. The selection program used at Badajoz (Spain) has originated ecotypes which have been described by Gomez Pitera (1985) and Gonzalez et al. (1986). These ecotypes have short cycles, high level of hardseedness, high seed production and long flowering period. The final stage in the selection of pasture plants must include the evaluation under grazing. Subclover has a high natural capacity of seed burial and a perfect adaptation to high stocking rates and continuous grazing by its morphological and physiological characteristics (Morley et al., 1965 ; Rossiter, 1966; Katznelson, 1974). The objective of this study was to evaluate the new ecotypes and varieties of subclover under real grazing conditions
Morphological and Physiological Growth Aspects of Three Tropical Grasses
Full text linkForage plants differ considerably regarding their ability to recover from grazing. Forage regrowth is determined by shoot apex survival (Sheard and Winch, 1966); leaf area (Ward and Blaser, 1961) ; non-structural carbohydrate content (Ward and Blaser, 1961 ; Brown and Blaser, 1965) and tillering potential (Paulsen and Smith, 1969). Little is known about these concepts regarding tropical grasses
