- OBJECTIVES: Survival after out-of-hospital cardiac arrest (OHCA) varies between communities, due in part to variation in the methods of measurement. The Utstein template was disseminated to standardize comparisons of risk factors, quality of care, and outcomes in patients with OHCA. We sought to assess whether OHCA registries are able to collate common data using the Utstein template. A subsequent study will assess whether the Utstein factors explain differences in survival between emergency medical services (EMS) systems. STUDY DESIGN: Retrospective study. SETTING: This retrospective analysis of prospective cohorts included adults treated for OHCA, regardless of the etiology of arrest. Data describing the baseline characteristics of patients, and the process and outcome of their care were grouped by EMS system, de-identified, and then collated. Included were core Utstein variables and timed event data from each participating registry. This study was classified as exempt from human subjects' research by a research ethics committee. MEASUREMENTS AND MAIN RESULTS: Thirteen registries with 265 first-responding EMS agencies in 13 countries contributed data describing 125,840 cases of OHCA. Variation in inclusion criteria, definition, coding, and process of care variables were observed. Contributing registries collected 61.9% of recommended core variables and 42.9% of timed event variables. Among core variables, the proportion of missingness was mean 1.9±2.2%. The proportion of unknown was mean 4.8±6.4%. Among time variables, missingness was mean 9.0±6.3%. CONCLUSIONS: International differences in measurement of care after OHCA persist. Greater consistency would facilitate improved resuscitation care and comparison within and between communities.

- Objective: to evaluate the effectiveness of women centred interventions during pregnancy and birth to increase rates of vaginal birth after caesarean. Design: we searched bibliographic databases for randomised trials or cluster randomised trials on women centred interventions during pregnancy and birth designed to increase VBAC rates in women with at least one previous caesarean section. Comparator groups included standard or usual care or an alternative treatment aimed at increasing VBAC rates. The methodological quality of included studies was assessed independently by two authors using the Effective Public Health Practice Project quality assessment tool. Outcome data were extracted independently from each included study by two review authors. Findings: in total, 821 citations were identified and screened by title and abstract; 806 were excluded and full text of 15 assessed. Of these, 12 were excluded leaving three papers included in the review. Two studies evaluated the effectiveness of decision aids for mode of birth and one evaluated the effectiveness of an antenatal education programme. The findings demonstrate that neither the use of decision aids nor information/education of women have a significant effect on VBAC rates. Nevertheless, decision-aids significantly decrease women's decisional conflict about mode of birth, and information programmes significantly increase their knowledge about the risks and benefits of possible modes of birth. Key conclusions: few studies evaluated women-centred interventions designed to improve VBAC rates, and all interventions were applied in pregnancy only, none during the birth. There is an urgent need to develop and evaluate the effectiveness of all types of women-centred interventions during pregnancy and birth, designed to improve VBAC rates. Implications for practice: decision-aids and information programmes during pregnancy should be provided for women as, even though they do not affect the rate of VBAC, they decrease women's decisional conflict and increase their knowledge about possible modes of birth.

- Compared with other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes. Here we report observing one F-1-hybrid individual that developed into a functional hermaphrodite after crossing two closely-related sexually reproducing species of cichlids. Microsatellite alleles segregated consistent with selfing and Mendelian inheritance and we could rule out different modes of parthenogenesis including automixis. We discuss why selfing is not more commonly observed in vertebrates in nature, and the role of hybridization in the evolution of novel traits.
