RESUMO

Insurance coverage of abortion varies widely across the United States and is an extensively debated issue. Medicaid coverage of abortion is particularly relevant because the majority of abortion patients are poor or low-income and are thus often covered by Medicaid. Since the Hyde Amendment was first passed in 1976, federal Medicaid funds have been banned from covering the costs of elective abortion. Although states are allowed to use their own funds to cover abortions for their Medicaid recipients, only 17 states currently do so. Of these 17 states, only five cover abortion costs voluntarily; the others do so pursuant to court order. The medical literature includes few ethical analyses of the Hyde Amendment's ban on Medicaid funding of elective abortions. To fill this gap, we perform an ethical analysis of federal policy to fund elective abortions using a consequentialist approach focused on consequences for pregnant women and their children.

RESUMO

In previous studies, we demonstrated that single-chain variable fragments (scFvs) from anti-human immunodeficiency virus (HIV) Env monoclonal antibodies act as entry inhibitors when tethered to the surface of target cells by a glycosyl-phosphatidylinositol (GPI) anchor. Interestingly, even if a virus escapes inhibition at entry, its replication is ultimately controlled. We hypothesized that in addition to functioning as entry inhibitors, anti-HIV GPI-scFvs may also interact with Env in an infected cell, thereby interfering with the infectivity of newly produced virions. Here, we show that expression of the anti-HIV Env GPI-scFvs in virus-producing cells reduced the release of HIV from cells 5- to 22-fold, and infectivity of the virions that were released was inhibited by 74% to 99%. Additionally, anti-HIV Env GPI-scFv X5 inhibited virion production and infectivity after latency reactivation and blocked transmitter/founder virus production and infectivity in primary CD4+ T cells. In contrast, simian immunodeficiency virus (SIV) production and infectivity were not affected by the anti-HIV Env GPI-scFvs. Loss of infectivity of HIV was associated with a reduction in the amount of virion-associated Env gp120. Interestingly, an analysis of Env expression in cell lysates demonstrated that the anti-Env GPI-scFvs interfered with processing of Env gp160 precursors in cells. These data indicate that GPI-scFvs can inhibit Env processing and function, thereby restricting production and infectivity of newly synthesized HIV. Anti-Env GPI-scFvs therefore appear to be unique anti-HIV molecules as they derive their potent inhibitory activity by interfering with both early (receptor binding/entry) and late (Env processing and incorporation into virions) stages of the HIV life cycle.IMPORTANCE The restoration of immune function and persistence of CD4+ T cells in HIV-1-infected individuals without antiretroviral therapy requires a way to increase resistance of CD4+ T cells to infection by both R5- and X4-tropic HIV-1. Previously, we reported that anchoring anti-HIV-1 single-chain variable fragments (scFvs) via glycosyl-phosphatidylinositol (GPI) to the surface of permissive cells conferred a high level of resistance to HIV-1 variants at the level of entry. Here, we report that anti-HIV GPI-scFvs also derive their potent antiviral activity in part by blocking HIV production and Env processing, which consequently inhibits viral infectivity even in primary infection models. Thus, we conclude that GPI-anchored anti-HIV scFvs derive their potent blocking activity of HIV replication by interfering with successive stages of the viral life cycle. They may be effectively used in genetic intervention of HIV-1 infection.

RESUMO

PURPOSE: Extracorporeal membrane oxygenation (ECMO) supports gas exchange and circulation in critically ill patients. This study describes a multidisciplinary approach to ECMO cannulation using the expertise of pediatric surgery (PS) and interventional radiology (IR). MATERIAL AND METHODS: Pediatric patients (<18 years) undergoing percutaneous cannulation for peripheral veno-arterial (VA) ECMO by PS and IR from April 2017 to May 2018 were included. Cardiac patients and children cannulated by PS alone were excluded. RESULTS: Five patients were included in the series. Median age was 16 [12.5-17] years and 3 were female. Median ECMO arterial and venous catheter sizes were 19 [17-22] Fr and 25 [25-28] Fr, respectively. Both catheters were placed in the common femoral vessels. A 6Fr antegrade distal perfusion cannula (DPC) was also placed in the superficial femoral artery by IR at the time of cannulation. The median time from admission to procedure start was 10 [7-50] hours and the children were on ECMO for a median length of 3.2 [2.3-4.8] days. There were two episodes of bleeding. No patients had loss of limb circulation. CONCLUSION: A multidisciplinary approach to peripheral VA ECMO cannulation is feasible and safe. Maintenance of limb perfusion by percutaneous placement and removal of DPC may be an advantage of this collaborative approach. LEVEL OF EVIDENCE: IV. TYPE OF RESEARCH: Case series.
