Labor induction in preeclampsia: is misoprostol more effective than dinoprostone?

OBJECTIVE: To compare the efficacy of vaginal misoprostol versus dinoprostone for induction of labor (IOL) in patients with preeclampsia according to the WHO criteria. STUDY DESIGN: Ninety-eight patients were retrospectively analyzed. A total of 47 patients received 3 mg dinoprostone suppositories every 6 h (max. 6 mg/24 h) whereas 51 patients in the misoprostol group received either 50 mug misoprostol vaginally every 12 h, or 25 mug every 6 h (max. 100 mug/24 h). Primary outcomes were vaginal delivery within 24 and 48 h, respectively. RESULTS: The probability of delivering within 48 h was more than three-fold higher in the misoprostol than in the dinoprostone group: odds ratio (OR)=3.48; 95% confidence interval (CI) 1.24, 10.30, whereas no significant difference was observed within 24 h (P=0.34). No correlation was seen between a ripe cervix prior to IOL and delivery within 24/48 h (P=0.33 and P=1.0, respectively). More cesarean sections were performed in the dinoprostone group due to failed IOL (P=0.0009). No significant differences in adverse maternal outcome were observed between both study groups, whereas more neonates (12 vs. 6) of the dinoprostone group were admitted to the NICU (P=0.068). CONCLUSION: This study suggests that misoprostol may have some advantages compared to dinoprostone, including improved efficacy and lower cost of the drug, even in cases of preeclampsia.

Oral misoprostol for third stage of labor: a randomized placebo-controlled trial

OBJECTIVE: To investigate whether orally administered misoprostol during the third stage of labor is efficient in reducing postpartum blood loss. METHODS: In a double-masked trial, during vaginal delivery women were randomly assigned to receive a single oral dose of misoprostol (600 microg) or placebo in third stage of labor, immediately after cord clamping. The third stage of labor was managed routinely by early cord clamping and controlled cord traction; oxytocin was administered only if blood loss seemed more than usual. Blood loss was estimated by the delivering physician and differences in hematocrit were measured before and after delivery. RESULTS: Mean (+/- standard error of the mean) estimated blood loss (345 +/- 19.5 mL versus 417 +/- 25.9 mL, P = .031) and hematocrit difference (4.5 +/- 0.9% versus 7.9 +/- 1.2%, P = .014) were significantly lower in women who received misoprostol than those who received placebo. Fewer women in the misoprostol group had postpartum hemorrhage (blood loss of at least 500 mL), but that difference was not statistically significant (7% versus 15%, P = .43). Additional oxytocin before or after placental separation was used less often in the misoprostol group (16% versus 38%, P = .047). There were no differences in the length of third stage of labor (8 +/- 0.9 minutes versus 9 +/- 1 minutes, P = .947). There were no differences in pain during third stage of labor, postpartum fever, or diarrhea, but shivering was more frequent in the misoprostol group. CONCLUSION: Oral misoprostol administered in the third stage of labor reduced postpartum blood loss and might be effective in reducing incidence of postpartum hemorrhage.

Biolimus-eluting stent with biodegradable polymer versus sirolimus-eluting stent with durable polymer for coronary revascularisation (LEADERS): a randomised non-inferiority trial

BACKGROUND: A novel stent platform eluting biolimus, a sirolimus analogue, from a biodegradable polymer showed promising results in preliminary studies. We compared the safety and efficacy of a biolimus-eluting stent (with biodegradable polymer) with a sirolimus-eluting stent (with durable polymer). METHODS: We undertook a multicentre, assessor-blind, non-inferiority study in ten European centres. 1707 patients aged 18 years or older with chronic stable coronary artery disease or acute coronary syndromes were centrally randomised by a computer-generated allocation sequence to treatment with either biolimus-eluting (n=857) or sirolimus-eluting (n=850) stents. The primary endpoint was a composite of cardiac death, myocardial infarction, or clinically-indicated target vessel revascularisation within 9 months. Analysis was by intention to treat. 427 patients were randomly allocated to angiographic follow-up, with in-stent percentage diameter stenosis as principal outcome measure at 9 months. The trial is registered with ClinicalTrials.gov, number NCT00389220. FINDINGS: We analysed all randomised patients. Biolimus-eluting stents were non-inferior to sirolimus-eluting stents for the primary endpoint at 9 months (79 [9%] patients vs 89 [11%], rate ratio 0.88 [95% CI 0.64-1.19], p for non-inferiority=0.003, p for superiority=0.39). Frequency of cardiac death (14 [1.6%] vs 21 [2.5%], p for superiority=0.22), myocardial infarction (49 [5.7%] vs 39 [4.6%], p=0.30), and clinically-indicated target vessel revascularisation (38 [4.4%] vs 47 [5.5%], p=0.29) were similar for both stent types. 168 (79%) patients in the biolimus-eluting group and 167 (78%) in the sirolimus-eluting group had data for angiographic follow-up available. Biolimus-eluting stents were non-inferior to sirolimus-eluting stents in in-stent percentage diameter stenosis (20.9%vs 23.3%, difference -2.2% [95% CI -6.0 to 1.6], p for non-inferiority=0.001, p for superiority=0.26). INTERPRETATION: Our results suggest that a stent eluting biolimus from a biodegradable polymer represents a safe and effective alternative to a stent eluting sirolimus from a durable polymer in patients with chronic stable coronary artery disease or acute coronary syndromes.

Teofilo Petriella : Marxist Revolutionary

The paper will examine the role Teofilo Petriella played in splitting Italian communities through Marxist agitation. As a strike leader on Mesabi Iron Range and in Copper Country, Petriella traveled throughout the Great Lakes region. In each community he found supporters among the discontented miners, while also facing strong opposition from Catholic priests and middle class community leaders. By examining his activities in both regions, I will illustrate the connectivity of Italian communities around Lake Superior, while also addressing religious and class conflict amongst the populations.
