    Increased government deficit has led the congress to reduce federal spending. Proposed budget cuts are intended to decrease government spending in several areas, including agriculture. Reductions in farm program spending could cause significant adverse effects on the financial situation of many farms, particularly to rice and cotton enterprises, due to their high reliance on farm program payments as a source of income. Representative rice and cotton operations of one, two, three, and four entities as single crop enterprises were considered and developed for use in this study. Farm enterprise sizes were determined by estimating the acreage level at which a one, two, three, and four entity operations would reach the most restrictive payment limit. Rice and cotton farms were considered to plant and harvest 85 percent of base acreage (100 percent of paid base acreage). For each enterprise evaluated, gross income, variable production costs, fixed equipment costs, and general farm overhead expenses are included in the analysis. Projections of income and expenses are made for a five-year period (2005-2009). For each year of simulation, random market prices and crop yields are generated to allow for inclusion of price and yield risk. Random domestic market prices, world market prices and crop yields per acre, for both rice and cotton, were generated. The analysis includes a comparison of a baseline simulation of projected income and expenses with six alternative program payment reduction scenarios. Continuation of current policy without reductions in farm program spending has shown to generate insufficient net farm income to both rice and cotton enterprises. One entity operations under the baseline scenario have resulted as being non-viable operations. Increasing reductions in program payments had a detrimental effect on the financial situation of both rice and cotton operations. The combination of 5 percent reduction in program payments along with a 10 percent decline in market prices resulted as the worse case scenario for all rice and cotton enterprises placing them in a higher risk of negative returns over variable and total costs. No program reductions below the baseline scenario are recommended for the viability of an already suffering agricultural sector

    Background: We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). Patients and methods: Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. Results: We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. Conclusion: Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.Fil: Efe, Cumali.

    Importance: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. Objectives: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. Design, Setting, and Participants: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. Main Outcomes and Measures: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. Results: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle-income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle-income countries vs upper-middle-income countries and HICs, 5.74 [95% CI, 4.30-7.68]). Conclusions and Relevance: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs

    40. p.En el Zamorano, se probaron 3 densidades de siembra con 4 números de frutos por planta en el cultivo de melón tutoreado bajo protección. Este estudio se realizó con la finalidad de ver el efecto de ambas variables sobre el peso y la forma del melón en comparación al sistema traiciona de siembra. Para lo anterior, se evaluaron 3 distanciamientos de siembra (0.20, 0.30 y 0.40 m) entre plantas, con 1.50 m entre hileras y 3 números de frutos por plantas (1, 2 y 3) además de un testigo absoluto a un distanciamiento de 0.30 m, sin restricción en el número de frutos y ninguna poda partir de quinto nudo. Se encontró que el distanciamiento fue el que mayormente afecto el peso de los frutos. La forma de los frutos no se vio influenciada por el distanciamiento entre plantas, sino más bien por el número de frutos en la planta. Se encontró que el tratamiento que produjo la mayor rentabilidad de los costos fue sembrado a 0.40 m y con 2 frutos por planta, seguido por el tratamiento sembrado a 0.30my 3 frutos por planta. El sistema tradicional a 0.30 m y sin restricción en el número de frutos, fue inferior a los dos tratamientos anteriores, pero si mostró ser superior al resto de los tratamientos del ensayo. En cuanto al peso, vale mencionar que el tratamiento a 0.40 m y un solo fruto por planta, fue el que produjo los frutos mis grandes y uniformes además de tener los costos más bajos de producción. En aquellos tratamientos donde mis de un fruto por planta fue asignado, el cuaje de los frutos, no permitió observar las verdaderas diferencias económicas, ya que pocas fueron las plantas que lograron llevar a cosecha sus 2 o 3 frutos. Se puede concluir entonces que si vale la pena realizar las prácticas de poda de frutos, ya que nos permite aumentar el rendimiento del cultivo en comparación al sistema tradicional sin poda, mejorando considerablemente la rentabilidad.1. índice de cuadros 2. índice de figuras 3.

    No full text
    Objective: Data on the frequency of cardiovascular disease in people living with human immunodeficiency virus from low- and middle-income countries is scarce. Methods: We performed an observational study based on data from a historical cohort of people living with human immunodeficiency virus in Colombia during a 10-year follow-up to describe the prevalence of cardiovascular risk factors and their behavior according to CD4 count. Results: One thousand patients were initially included, out of which 390 had a 10-year follow-up. The mean age was 34 (standard deviation 10) years, and 90% were male. We observed an increase in the prevalence of dyslipidemia (29%–52%, p  < 0.001) and obesity (1.1%–3.5%, p  < 0.001). Major cardiovascular events occurred in less than 1% of patients. Patients with a CD4 count <200 cells/mm 3 had a higher frequency of acute myocardial infarction and obesity. Conclusion: Over time, people living with human immunodeficiency virus present with an increasing prevalence of cardiovascular risk factors, particularly those with a lower CD4 count

    No full text
    Resumen: Objetivo: Valorar la efectividad de una estrategia de apoyo individualizado al empleo (IPS) en personas con enfermedad mental grave en la isla de Tenerife (España). Método: Pacientes de los Servicios de Salud Mental Comunitaria con trastornos mentales graves fueron asignados a dos grupos de forma aleatorizada. En uno de ellos se aplicó el método IPS (n = 124) y en el grupo control (n = 75) se asesoró en la manera habitual de búsqueda de empleo. Los pacientes fueron seguidos una media de 3,4 años y se analizó cuántos trabajaron al menos un día, el tiempo trabajado, los salarios, el número de contratos y el número de admisiones hospitalarias. Se usaron métodos estadísticos no paramétricos en la comparación de resultados (U de Mann-Whitney). Resultados: Los pacientes asignados al grupo IPS trabajaron al menos un día el 99%, frente al 75% del grupo control; trabajaron de media 30,1 semanas/año vs. 7,4; el salario mensual fue de 777,9 euros vs. 599,9 euros; el número de contratos por persona fue de 3,89 vs. 4,85, y los ingresos hospitalarios fueron 0,19 vs. 2,1. Conclusión: La estrategia IPS es efectiva en la integración laboral de personas con enfermedad mental grave, logrando que trabajen más tiempo, tengan mayor salario y menos ingresos hospitalarios, en un contexto social de alto desempleo. Abstract: Objective: To assess the effectiveness of an individual placement and support (IPS) strategy in people with severe mental disorders in Tenerife Island (Spain). Methods: Patients of Community Mental Health Services with severe mental disorders were randomly assigned to two groups. One of them received IPS (n = 124), and the control group (n = 75) was advised in the usual job search. Patients were followed up for an average of 3.4 years and an analysis was made of how many patients worked at least one day, working hours, wages, the number of contracts and the number of hospital admissions. Non-parametric methods were used to compare the results (Mann-Whitney U test). Results: The percentage of patients who worked at least one day was 99% in the IPS group compared with 75% in the control group; they worked on average 30.1 weeks per year vs 7.4; the monthly salary was € 777.9 vs € 599.9; the number of contracts per person was 3.89 vs 4.85, and hospital admissions were 0.19 vs 2.1. Conclusions: The IPS strategy is effective for the labour integration of people with severe mental illness getting them to work longer, have higher wages and fewer hospital admissions.

    OBJECTIVE: To explore cardiovascular fitness in 40 occupations using a nationally-representative 3 sample of the U.S. population. METHODS: Respondents aged 18–49 (n=3,354) from the 1999–2004 NHANES were evaluated for 5 cardiovascular fitness and classified into low, moderate, and high levels. Comparisons were 6 made among occupations. RESULTS: Of all U.S. workers, 16% had low, 36% moderate, and 48% high cardiovascular 8 fitness. Administrators, Health occupations, Wait staff, Personal services, and Agricultural 9 occupations had a lesser percentage of workers with low cardiovascular fitness compared to all 10 others. Sales workers, Administrative support, and Food preparers had a higher percentage of 11 workers with low cardiovascular fitness compared to all others. CONCLUSIONS: Cardiovascular fitness varies significantly across occupations, and those with limited physical activity have higher percentages of low cardiovascular fitness. Workplace strategies are needed to promote cardiovascular fitness among high-risk occupations
