A randomized trial of hyperimmune globulin to prevent congenital cytomegalovirus

Abstract: Background Congenital infection with human cytomegalovirus (CMV) is a major cause of morbidity and mortality. In an uncontrolled study published in 2005, administration of CMV-specific hyperimmune globulin to pregnant women with primary CMV infection significantly reduced the rate of intrauterine transmission, from 40% to 16%. Methods We evaluated the efficacy of hyperimmune globulin in a phase 2, randomized, placebo-controlled, double-blind study. A total of 124 pregnant women with primary CMV infection at 5 to 26 weeks of gestation were randomly assigned within 6 weeks after the presumed onset of infection to receive hyperimmune globulin or placebo every 4 weeks until 36 weeks of gestation or until detection of CMV in amniotic fluid. The primary end point was congenital infection diagnosed at birth or by means of amniocentesis. Results A total of 123 women could be evaluated in the efficacy analysis (1 woman in the placebo group withdrew). The rate of congenital infection was 30% (18 fetuses or infants ...

Gemcitabine and Cisplatin Versus Mitomycin, Ifosfamide, and Cisplatin in Advanced Non–Small-Cell Lung Cancer: A Randomized Phase III Study of the Italian Lung Cancer Project

Abstract: PURPOSE: To compare gemcitabine and cisplatin (GC) with mitomycin, ifosfamide, and cisplatin (MIC) chemotherapy in patients with stage IIIB (limited to T4 for pleural effusion and N3 for supraclavicular lymph nodes) or stage IV non–small-cell lung cancer (NSCLC). The end points were the evaluation of quality of life (QoL), response rates, survival, and toxicity. PATIENTS AND METHODS: Three hundred seven patients were randomized to receive either gemcitabine 1,000 mg/m2 on days 1, 8, and 15 plus cisplatin 100 mg/m2 on day 2, every 28 days, or mitomycin 6 mg/m2, ifosfamide 3,000 mg/m2, and mesna on day 1 plus cisplatin 100 mg/m2 on day 2, every 28 days. The whole-blood cell count was repeated on day 1 in both arms and weekly in the GC arm before each gemcitabine administration. RESULTS: No major differences in changes in QoL were observed between the two treatment arms. The objective response rate was 38% in the GC arm compared with 26% in the MIC arm (P = .029). The median survival time was 8.6 months in t...

Glucocorticoid-induced osteoporosis: an update.

Abstract: Glucocorticoid-induced osteoporosis occurs in two phases: a rapid, early phase in which bone mineral density is reduced, possibly as a result of excessive bone resorption, and a slower, progressive phase in which bone mineral density declines because of impaired bone formation. Although the indirect effects of glucocorticoids on bone are evident, their direct effects on osteoblasts, osteoclasts and osteocytes are primarily operative in the pathogenesis of glucocorticoid-induced osteoporosis. The management of patients exposed to glucocorticoids includes general health measures, sufficient calcium and vitamin D, and reducing the therapeutic regimen to the minimal effective dose. The gold standard in the pharmacological treatment of glucocorticoid-induced osteoporosis in postmenopausal women involves the use of bisphosphonates, which should be started soon after beginning chronic glucocorticoid therapy. Anabolic and alternative therapeutic strategies are currently under investigation in glucocorticoid-induced osteoporosis.

A Consistent Reaction Scheme for the Selective Catalytic Reduction of Nitrogen Oxides with Ammonia

Abstract: For the first time, the standard and fast selective catalytic reduction (SCR) of NO by NH3 are described in a complete catalytic cycle that is able to produce the correct stoichiometry while allowing adsorption and desorption of stable molecules only. The standard SCR reaction is a coupling of the activation of NO by O2 with the fast SCR reaction, enabled by the release of NO2. According to the scheme, the SCR reaction can be divided into an oxidation of the catalyst by NO + O2 and a reduction by NO + NH3; these steps together constitute a complete catalytic cycle. Furthermore, both NO and NH3 are required in the reduction, and finally, oxidation by NO + O2 or NO2 leads to the same state of the catalyst. These points are shown experimentally for a Cu-CHA catalyst by combining in situ X-ray absorption spectroscopy (XAS), electron paramagnetic resonance (EPR), and Fourier transform infrared spectroscopy (FTIR). A consequence of the reaction scheme is that all intermediates in fast SCR are also part of the s...
