The purpose of this study was to explore the perceptions of violence against women (VAW) held by Haitian men to gain a better understanding of why VAW occurs. Women in Haiti have experienced significant violence, both before and following the 2010 earthquake. Fifteen men aged 26 to 47 participated in a focus group. The data revealed three themes: men's beliefs about VAW and its context, factors influencing VAW, and recommended interventions. When approaching VAW, men must be part of the collective effort. Their insights are valuable when planning and implementing interventions to decrease VAW in Haiti and worldwide. 相似文献

Recombinant humanized anti-IL-2 receptor antibody (daclizumab) produces responses in patients with moderate aplastic anemia 总被引:9,自引:2,他引:9
In contrast to severe aplastic anemia (sAA), the appropriate management of patients with moderate pancytopenia is unclear. In this study, we examined the efficacy of a humanized monoclonal antibody recognizing interleukin-2 receptor (daclizumab), which has proven to be a successful immunosuppressive agent in solid organ and bone marrow transplantation. We treated 17 patients with moderate aplastic anemia (mAA) with 1 mg/kg every 2 weeks for 3 months. mAA was defined as depression of 2 of the 3 blood counts: absolute neutrophil count 1200/mm3 or less, platelet count 70,000/mm3 or less, hemoglobin level 8.5 g/dL or lower, and absolute reticulocyte count 60,000/mm3 or less. The primary end point of our protocol was a hematologic response in at least one affected peripheral blood value. Daclizumab had little toxicity. Six of the 16 (38%) evaluable patients responded to treatment. Two patients with previously chronic disease showed complete return of normal counts, which were sustained for more than 2 years following treatment. Four patients had single-lineage responses. Two previously transfusion-dependent patients became transfusion independent; one patient with many neutropenia-related infections had a normal neutrophil count following treatment. Daclizumab appears safe; its efficacy in this pilot protocol suggests that expanded study of this monoclonal antibody in immune-mediated bone marrow failure syndrome is warranted. 相似文献

Selleri et al demonstrate that healthy donors given granulocyte-colony-stimulating factor (G-CSF) have increases in plasma soluble plasminogen activator receptor (suPAR) levels, which in turn induces chemotaxis of CD34 cells. Selleri et al's findings help better define the complicated mechanism of stem cell mobilization by G-CSF and point to a wide role for uPAR in cell surface adhesion and recognition. 相似文献

Cystinuria is characterized by cystine stone formation and loss of renal function. Conservative therapy is generally ineffective and penicillamine therapy can be complicated by serious side effects. To our knowledge, we report the first clinical use of captopril in the treatment of homozygous cystinuria in two siblings. In the first patient, a 70% reduction in cystine excretion was observed after 26 weeks of therapy with 150 mg/d of captopril. Discontinuation of use of the drug resulted in a return to baseline cystine excretion, further loss of renal function, and nephrotic range proteinuria. Repeated treatment with captopril stabilized renal function, reduced proteinuria, and returned cystine excretion to near normal levels. In the second patient, cystine excretion was reduced by 93% after nine weeks of therapy with 75 mg/d of captopril. No adverse side effects were observed in either patient. Formation of the captopril-cysteine disulfide accounts for part of the reduction in cystine excretion but other mechanisms probably contribute. Because captopril-cysteine disulfide is 200 times more soluble than cystine, long-term captopril therapy may be useful in the treatment of cystinuria. 相似文献

BACKGROUND : Fever, chills, and reduced platelet recovery may result when platelets are transfused simultaneously with amphotericin B. Amphotericin B reportedly increases the pitting of membranes in stored platelets. STUDY DESIGN AND METHODS : The effects of amphotericin B and another antifungal agent, fluconazole, on platelet membrane glycoproteins (GP) were examined by the incubation of split aliquots of fresh and stored platelet concentrates (PCs) with these drugs for 3 days in storage bags. To determine the effect of storage, PCs were stored for 5 days, and aliquots removed on Days 1 through 5 were placed in platelet storage bags with 4 micrograms per mL of amphotericin B for 2 to 6 hours. Membrane glycoprotein expression was assessed by flow cytometry with fluorescein isothiocyanate-labeled monoclonal antibodies (MoAbs) directed against the following antigens: GPIb (CD42b), CD63 (an activation protein), P-selectin (CD62), and GPIIb/IIIa (CD41a). RESULTS : Amphotericin B produced a concentration-dependent decrease in the surface binding of CD42b MoAb with no consistent changes in the binding of CD41a, CD63, or CD62 MoAbs after a 3-day exposure. Stored but not fresh PCs showed decreased binding of MoAb CD42b after a 6-hour exposure to amphotericin B (4 micrograms/mL). Fluconazole produced no changes. When the binding of MoAb CD42b to permeabilized platelets was used to measure total platelet content, amphotericin B (4 micrograms/mL) decreased MoAb CD42b binding to a similar degree in fresh and stored platelets. Inhibition of aggregation to ADP and collagen and ADP and epinephrine was seen in stored but not fresh PCs. CONCLUSION : Therapeutic levels of amphotericin B resulted in partial loss of total platelet GPIb in fresh and stored PCs, but decreased surface expression of platelet membrane GPIb only in stored platelets. This difference between fresh and stored platelets may be related to the limited reservoir of GPIb available for redistribution to the membrane in the previously stored PCs and may account for the decreased recovery of transfused platelets observed in some patients receiving amphotericin B. 相似文献
