The effect of torasemide and furosemide therapy was compared in 50 patients who had chronic heart failure and symptoms [NYHA class II-III] despite long-term therapy with both low-dose furosemide and angiotensin-converting enzyme inhibitors. In this randomized 6-month, open-label trial, baseline and follow-up echocardiograms and neurohumoral assays were obtained in 25 group F patients (continued same dose of oral furosemide at 20-40 mg/day) and in 25 group T patients (received torasemide at 4-8 mg/day in place of furosemide). At 6 months, parameters were unchanged in group F whereas the group T patients had a lower left ventricular end-diastolic diameter (p<0.005) and left ventricular mass index (p<0.005) with improved Doppler filling parameters, decreased plasma B-type natriuretic concentration (p<0.001) and increased plasma concentrations of active renin (p<0.005) and aldosterone (p<0.001). The magnitude of these changes appeared dose dependent and it is suggested these favorable effects of switching from furosemide to torasemide may be related to aldosterone receptor blockade.

The aim of this study was to determine whether the bone-morphogenetic proreins-2 (BMP-2) or -7 (BMP-7) levels in follicular fluid (FF) are associated with success in oocyte fertilization during assisted reproductive technology (ART) treatment. Twenty-four cycles in 24 patients who underwent oocyte retrieval in Sugiyama clinic were included in this retrospective study. The patients were divided into two groups according to the success or failure of fertilization. FF samples were obtained from a single follicle in each patient, and the levels of BMP-2, BMP-7, Anti-Müllerian hormone (AMH), estradiol and progesterone from FF were measured, and evaluated in relation to the ART outcomes. The BMP-2 levels correlated positively with the AMH levels in FF (r(2) = 0.4928), but there was no statistically significant difference between BMP-7 and AMH levels. The BMP-2 and BMP-7 levels had no relation with either progesterone or estradiol levels, but BMP-2 levels in the fertilized group were significantly higher than those in the unfertilized group (P < 0.05). The BMP-2 levels in FF positively correlated with the AMH levels in FF, and those in the fertilized group were significantly higher than in the unfertilized group. Therefore, the BMP-2 levels in FF could be a predictive marker for fertilization.

A causal relationship was noted between the number of rupture of the fetal membranes, delivery and barometric pressure, suggesting that low barometric pressure induces rupture of the fetal membranes and delivery.
