Changes to the Noninsured Crop Disaster Assistance Program Under the Agricultural Act of 2014: Their Potential Risk Reduction Impacts

ERS examines impacts of the Buy-Up coverage addition to the Noninsured Crop Disaster Assistance Program (NAP) on expected payments, producers' risk reduction, and NAP enrollment by type of producer and crops

Agricultural and Food Policy Response to COVID-19

We provide an overview of the major emergency actions taken to address food and agriculture needs during the pandemic. We focus primarily on the Coronavirus Food Assistance Program, a direct payment program to producers administered by the U.S. Department of Agriculture, highlighting its uniquely broad scope

Histopathology of aseptic necrosis of the femoral head in sickle cell disease

This study compares the histopathology of bone biopsies from patients suffering from sickle cell anaemia (homozygote SS) to heterozygote patients (SA) and homozygotes with aseptic osteonecrosis (AA). The sensitivity to bacterial infection of sickle cell patients raises the question of the aetiology of sepsis in the onset of the necrosis. To our knowledge this study is the first to analyse the histopathology of osteonecrosis of the femoral head, at its early stages, in sickle cell anaemia. At the University Hospital of Pointe-à-Pitre, from 1994 to 2007, 38 bone biopsies were obtained from adult patients with avascular necrosis of the femoral head at the time of a core decompression procedure (SS, SC: 27; AS: 5; AA: 6). The histology of the biopsies confirmed the necrosis; all bacteriological cultures were negative. Patients displaying one S gene (SS, SC, AS) compared to homozygote subjects (AA) showed a significant increase of a nonspecific inflammatory granulomatosis (p = 0.003). No relationship was observed between the radiological stages and the histology whatever the genotype (p = 0.1). Inflammatory histopathology without sepsis or advanced alteration characterises the early stages of sickle cell necrosis. This inflammatory process is absent in idiopathic avascular necrosis.Journal ArticleSCOPUS: cp.jinfo:eu-repo/semantics/publishe
