Observational Study
Epidural analgesia during labour and stress markers in the newborn.
Labour and modes of delivery can influence the plasma levels of stress hormones and cytokines involved in pathophysiologic cascade, potentially damaging brain development of the newborn. This prospective observational, single-centre, case-control, non-profit study aimed to detect potential differences in foetal well-being such as stress neuroendocrine responses. Quantitative determinations of the stress markers interleukin (IL)-1β, IL-8, and β-endorphin were compared between the control group and the epidural analgesia group. ⋯ What do the results of this study add? This study found no significative differences in blood stress response markers between the epidural analgesia group and the control group. Under this study circumstances we found out that epidural analgesia does not significantly influence the newborn's well-being during labour and delivery. What are the implications of these findings for clinical practice and/or further research? These findings must be confirmed by further studies to verify whether epidural analgesia is safe for the newborn's development.

The influence of Body Roundness Index on sensorial block level of spinal anaesthesia for elective caesarean section: an observational study.
In this prospective trial, we investigate the effectiveness of maternal Body Roundness Index in predicting the spread of spinal anaesthesia and vasopressor requirement in parturients receiving spinal anaesthesia during the elective caesarean section. We prospectively enrolled 175 parturients. Spinal anaesthesia performed with 10 mg 0.5% hyperbaric bupivacaine at the L3-L4 intervertebral space and the optimal cut-off points of the BRI evaluated as 6.59 by receiver operating characteristic analysis calculating area under the curve. ⋯ An ellipsoid body shape might affect the spread of spinal anaesthesia. What do the results of this study add? Our results show that the BRI was as an independent risk factor associated with maximum sensory block level in term parturients undergoing caesarean delivery. What are the implications of these findings for future clinical practice and/or further research? A future study would present the possibility to design a formula for the exact amount of local anaesthetic to be used in spinal anaesthesia with the aid of maternal BRI.

Observational Study
Analgesia nociception index as a tool to predict hypotension after spinal anaesthesia for elective caesarean section.
Arterial hypotension is the main disadvantage of spinal anaesthesia (SA) for caesarean delivery with deleterious effects on maternal-foetal outcomes. Recently, a non-invasive device 'analgesia nociception index' (ANI) has been developed to evaluate the parasympathetic component of the nervous autonomous system. The aim of this study was to evaluate the ability of ANI to predict the risk of hypotension after SA for elective caesarean section. ⋯ What are the implications of these findings for clinical practice and/or further research? ANI is an effective tool in predicting the risk of spinal anaesthesia-related hypotension. These findings are of potential clinical importance in the obstetrical anaesthesia setting. Further studies are required in order to implement this simple tool and optimise prophylactic measures especially vasopressors.

Comparative Study
Does carbetocin for prevention of postpartum haemorrhage at caesarean section provide clinical or financial benefit compared with oxytocin?
Postpartum haemorrhage is a major cause of maternal morbidity and mortality worldwide. A recent Cochrane review of carbetocin (long-acting oxytocin analogue) concluded that its use decreased additional uterotonic requirements, however, no included studies compared its use against intravenous bolus oxytocin. The majority of studies of carbetocin have considered its use in vaginal delivery; no studies have examined the economic implications of its use. ⋯ A range of clinical outcomes were observed including frequency of postpartum haemorrhage, estimated blood loss, transfusion requirements, change in haemoglobin or haemodynamics, use of additional uterotonics and perioperative recovery. Finally, a composite financial analysis was performed. No clinically significant benefit was found, however associated costs increased by £18.52/patient.

Association between basal proteinuria levels and pregnancy outcomes in familial Mediterranean fever.
We aimed to investigate whether proteinuria in the first trimester of pregnancy in Familial Mediterranean fever (FMF) patients has an impact on pregnancy outcome and perinatal and neonatal outcome of pregnancies. A total of 66 pregnant with FMF were compared with healthy controls at the same gestational weeks. Patients with FMF had a higher antenatal hospitalisation rate (34.8% vs. 6.1%, respectively, p < .01) and higher rate of 2 or more miscarriages. ⋯ However, our study population is relatively small. It will contribute to comprehensive studies involving a larger population. Future studies should be performed to investigate the effects of basal proteinuria in pregnancy with FMF.
