STUDY OBJECTIVES Full recovery after cardiopulmonary resuscitation (CPR) is poor. We hypothesized that the coadministration of epinephrine, a beta-blocker such as atenolol, and a calcium sensitizer such as levosimendan during CPR would improve survival and postresuscitation myocardial function. METHODS Ventricular fibrillation was induced in 60 piglets, which were left untreated for 8 minutes before attempted resuscitation. Animals were randomized into 4 groups (n = 15), to receive epinephrine (group E), epinephrine + atenolol (group E + A), epinephrine + levosimendan (group E + L) and epinephrine + atenolol + levosimendan (group E + A + L) during CPR. Electrical defibrillation was attempted 2 minutes after drug administration. RESULTS Five animals in group E survived for 48 hours in comparison to 8 animals in groups E + A and E + L and 12 animals in group E + A + L. Postresuscitation cardiac output was significantly better in the animals of group E + A + L. Troponin I remained significantly lower in groups E + A and E + A + L. Serum astroglial protein (S-100) and neuron-specific enolase values in group E + L and E + A + L were statistically lower than those measured in groups E and E + A during the entire observation period. The neurologic alertness score was higher in group E + A + L compared to groups E and E + A. CONCLUSIONS The administration of a drug combination of epinephrine + atenolol + levosimendan, when given during CPR, in a pig model of cardiac arrest, results in improved 48-hour survival and improves postresuscitation cardiac function.

To investigate the fetoplacental leptin circulation in gestational diabetes, we compared cord leptin and insulin levels in 17 healthy pregnant women and 17 women with gestational-onset diabetes. Leptin levels in the umbilical arteries (mean - SD 1·80 - 0·76 ng/ml) were significantly ( P <0·006) lower than those in umbilical veins (2·67 - 0·98 ng/ml) in normal pregnancies. Similarly, leptin levels in umbilical veins (mean - 4·59 - 1·60 ng/ml) were significantly ( P <0·001) higher than those in umbilical arteries (mean - SD 2·08 - 0·90 ng/ml) in gestational diabetes. However, leptin levels in umbilical veins were significantly higher ( P <0·002) in gestational diabetes than those in controls. Additionally, in women with diabetes but not in controls, the birth weight and the cord leptin concentrations were positively related to cord insulin levels. We conclude that there is a hyperleptinaemia in the fetoplacental circulation in pregnant women with carbohydrate intolerance and in these cases insulin and leptin may have antagonist roles regarding fetal development.

BACKGROUND In addition to its role in the endogenous control of erythropoiesis, recombinant human erythropoietin (rh-EPO) has been shown to exert tissue protective properties in various experimental models. However, its role in the cardiac arrest (CA) setting has not yet been adequately investigated. AIM The aim of this study is to examine the effect of rh-EPO in a pig model of ventricular fibrillation (VF)-induced CA. METHODS Ventricular fibrillation was electrically induced in 20 piglets and maintained untreated for 8 minutes before attempting resuscitation. Animals were randomized to receive rh-EPO (5000 IU/kg, erythropoietin [EPO] group, n = 10) immediately before the initiation of chest compressions or to receive 0.9% Sodium chloride solution instead (control group, n = 10). RESULTS Compared with the control, the EPO group had higher rates of return of spontaneous circulation (ROSC) (100% vs 60%, P = .011) and higher 48-hour survival (100% vs 40%, P = .001). Diastolic aortic pressure and coronary perfusion pressure during cardiopulmonary resuscitation were significantly higher in the EPO group compared with the control group. Erythropoietin-treated animals required fewer number of shocks in comparison with animals that received normal saline (P = .04). Furthermore, the neurologic alertness score was higher in the EPO group compared with that of the control group at 24 (P = .004) and 48 hours (P = .021). CONCLUSION Administration of rh-EPO in a pig model of VF-induced CA just before reperfusion facilitates ROSC and improves survival rates as well as hemodynamic variables.

Thrombophilic genetic factors have been shown to play an important role in implantation outcome after in vitro fertilisation (IVF). In this pilot study we investigated the frequencies of glycoprotein Ia (GpIa)-C807T and GpIIIa-PlA1/PlA2 polymorphisms in 60 nulligravidae women with a history of unexplained IVF implantation failures and compared them with 60 healthy fertile women. We found statistically significant associations between the GpIa-C807T and GpIIIa-PlA1/PlA2 polymorphisms and IVF implantation failure (odds ratio [OR] = 3.45, 95% confidence interval [CI]: 1.63–7.30, p = 0.001; and OR = 2.86, 95% CI: 1.27–6.45, p = 0.010, respectively) with the risk being higher for combined carriers of GpIa-807T and GpIIIa-PlA2 alleles (OR = 10.13, 95% CI: 2.85–35.99, p < 0.001), suggesting a synergistic effect of the two polymorphisms. The above associations were strongest for the youngest age group. Our results indicate that GpIa-807T and GpIIIa-PlA2 may be susceptibility alleles for IVF implantation failure.

Abstract The aim of the study was to investigate the combined impact of the genetic heterogeneity of the glycoproteins Ia (GpIa) and IIIa (GpIIIa) and the platelet-endothelial cell adhesion molecule-1 (PECAM-1) and P-Selectin genes on IVF embryo transfer implantation failures (IVF-ET failures). Sixty nulligravida women with previous IVF-ET failures and 60 fertile controls were genotyped for the GpIa-C807T, GpIIIa-PlA1/PA2, PECAM-1-C373G (Leu125Val) and P-Selectin-A37674C (Thr715Pro) polymorphisms by pyrosequencing. Compared with wild-type combined homozygotes, carriers of combinations of risk alleles in two gene loci were at significantly increased risk for IVF-ET failure, whereas carriers of the combination of GpIa-807T, GpIIIa-PlA2 and PECAM-1-373G alleles had OR = 52.50 (95%CI: 4.05–680.95, p < .001). The area under the receiver-operating characteristic curve (AUC) based on the number of polymorphisms and the number of risk alleles per subject was 75.4% (95%CI: 66.7%–82.8%, p < .001) and 72.5% (95%CI: 63.6%–80.3%, p < .001), respectively. The OR per polymorphism and risk allele increase was 4.26 (95%CI: 2.15–8.41, p < .001) and 2.85 (95%CI: 1.71–4.76, p < .001), respectively. The above associations were more robust among younger women. The combined analysis of these polymorphisms revealed strong association of combined carriers with IVF-ET failures especially for younger women and provided a genetic risk score with good diagnostic accuracy in the prediction of IVF-ET failures.
