Cervical shortening was defined as a cervical length of 2.5 cm or less before 24 weeks’ gestation. Patients with cervical shortening managed with cerclage were compared to those managed expectantly. The primary outcome was the gestational age at delivery, with secondary outcomes including birth weight, neonatal intensive care unit length of stay, and composite

neonatal outcome. Statistical significance was defined as P smaller than .05. Results-Sixteen patients underwent cerclage placement versus 8 managed expectantly (control group). The median gestational ages at delivery were similar between the groups (cerclage, 31.3 weeks; interquartile range [IQR], 29.3-32.3 weeks; control, 29.8 weeks; IQR, 27.5-32.4 weeks; P = .71). The median birth weights were also similar between the groups (cerclage, 1283 g; IQR, 800-1626 g; control, 1109 g; IQR, 776 1500 g; P = .54). There was no significant Panobinostat check details difference in composite neonatal outcomes between the cerclage and control groups (P = .67). Conclusions-In this limited case-control study, we found no benefit in terms of pregnancy prolongation or neonatal outcomes with cerclage placement for triplet gestations complicated by an asymptomatic short cervix.”

Compound 1 exhibits a novel fanlike Zn15 cluster, which is the highest-nuclearity Zn cluster with 2,6-H2bptp

reported thus far. In 2 or 3 (M = Zn/Cd), each ligand coordinates to three M2+ ions, to form an M8L6 cluster. The structure of compound 4 is a Ag-6 cluster-based 1D chain, where each hexanuclear [Ag-6(2,6-Hbptp)(2,6-bptp)(3)](-) cluster links its equivalent ones via sharing the Ag atom. Compound 5 contains two kinds of Ag-6 clusters, and the alternating arrangement of them gives the final structure. It is worth mentioning that the AgAg bond distances in 4 and 5 are relatively very short and suggest a closed-shell d(10)-d(10) argentophilic interaction. The luminescence properties of compounds 15 have been researched at ambient and low temperatures. Interestingly, the emission intensities of 15 increase gradually upon cooling. A new strong emission band for 4 appears at 610 nm exhibiting red-orange luminescence. The low-energy emissions (620 nm) of 5 gradually blue shift to shorter wavelengths.
