Standardized systematic search strategies facilitate rigor in research. Current search tools focus on retrieval of quantitative research. In this article we address issues relating to using existing search strategy tools, most typically the PICO (Population, Intervention, Comparison, Outcome) formulation for defining key elements of a review question, when searching for qualitative and mixed methods research studies. An alternative search strategy tool for qualitative/mixed methods research is outlined: SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, Research type). We used both the SPIDER and PICO search strategy tools with a qualitative research question. We have used the SPIDER tool to advance thinking beyond PICO in its suitable application to qualitative and mixed methods research. However, we have highlighted once more the need for improved indexing of qualitative articles in databases. To constitute a viable alternative to PICO, SPIDER needs to be refined and tested on a wider range of topics.

Background Pregnancy after perinatal death is characterised by elevated stress and anxiety, increasing the risk of adverse short-term and long-term outcomes.Objectives This metasynthesis aimed to improve understanding of parents' experiences of maternity care in pregnancy after stillbirth or neonatal death.Search strategy Six electronic databases were searched using predefined search terms.Selection criteria English language studies using qualitative methods to explore the experiences of parents in pregnancy after perinatal loss, were included subject to quality appraisal framework.Data collection and analysis Searches were initiated in December 2011 and finalised in March 2013. Studies were synthesised using an interpretive approach derived from meta-ethnography.Main results Fourteen studies were included in the synthesis, graded A (no or few flaws, high trustworthiness; n = 5), B (some flaws, unlikely to affect trustworthiness; n = 5) and C (some flaws, possible impact on trustworthiness; n = 4). Three main themes were identified; co-existence of emotions, helpful and unhelpful coping activities and seeking reasssurance through interactions.Conclusion Parents' experiences of pregnancy are profoundly altered by previous perinatal death; conflicted emotions, extreme anxiety, isolation and a lack of trust in a good outcome are commonly reported. Emotional and psychological support improves parents' experiences of subsequent pregnancy, but the absence of an evidence base may limit consistent delivery of optimal care within current services.

Topical oils on baby skin may contribute to development of childhood atopic eczema. A pilot, assessor-blinded, randomized controlled trial assessed feasibility of a definitive trial investigating their impact in neonates. One-hundred and fifteen healthy, full-term neonates were randomly assigned to olive oil, sunflower oil or no oil, twice daily for 4 weeks, stratified by family history of atopic eczema. We measured spectral profile of lipid lamellae, trans-epidermal water loss (TEWL), stratum corneum hydration and pH and recorded clinical observations, at baseline, and 4 weeks post-birth. Recruitment was challenging (recruitment 11.1%; retention 80%), protocol adherence reasonable (79-100%). Both oil groups had significantly improved hydration but significantly less improvement in lipid lamellae structure compared to the no oil group. There were no significant differences in TEWL, pH or erythema/skin scores. The study was not powered for clinical significance, but until further research is conducted, caution should be exercised when recommending oils for neonatal skin.

BackgroundPregnancy after stillbirth or neonatal death is an emotionally challenging life-event for women and adequate emotional support during pregnancy should be considered an essential component of quality maternity care. There is a lack of evidence surrounding the role of UK maternity services in meeting womens’ emotional and psychological needs in subsequent pregnancies. This study aimed to gain an overview of current UK practice and womens’ experiences of care in pregnancy after the death of a baby.MethodsOnline cross-sectional surveys, including open and closed questions, were completed on behalf of 138 United Kingdom (UK) Maternity Units and by 547 women who had experience of UK maternity care in pregnancy after the death of a baby. Quantitative data were analysed descriptively using SPSS software. Open textual responses were managed manually and analysed using the framework method.ResultsVariable provision of care and support in subsequent pregnancies was identified from maternity unit responses. A minority had specific written guidance to support care delivery, with a focus on antenatal surveillance and monitoring for complications through increased consultant involvement and technological surveillance (ultrasound/cardiotocography). Availability of specialist services and professionals with specific skills to provide emotional and psychological support was patchy. There was a lack of evaluation/dissemination of developments and innovative practice. Responses across all UK regions demonstrated that women engaged early with maternity care and placed high value on professionals as a source of emotional support. Many women were positive about their care, but a significant minority reported negative experiences. Four common themes summarised womens’ perceptions of the most important influences on quality and areas for development: sensitive communication and conduct of staff, appropriate organisation and delivery of services, increased monitoring and surveillance and perception of standard vs. special care.ConclusionsThese findings expose likely inequity in provision of care for UK parents in pregnancy after stillbirth or neonatal death. Many parents do not receive adequate emotional and psychological support increasing the risk of poor health outcomes. There is an urgent need to improve the evidence base and develop specific interventions to enhance appropriate and sensitive care pathways for parents.

ABSTRACT. Determination of circulating red cell volume (RCV) in anemic preterm infants is, in theory, a better indicator of transfusion needs than Hb concentration. Our study reports the results of RCV measurement using biotin labeling of red cells on 40 occasions in preterm infants of 25-34 wk gestation. In 20 infants, who had estimations made within 24 h of birth, the RCV varied between 17.7 and 66 mL/kg. Twenty measurements were made at a later age at the time of a blood transfusion. RCV values were between 13.1 and 41.5 mL/kg before transfusion. In 13 infants, RCV was determined simultaneously using two methods, biotin and dilution of autologous HbF with donor HbA at transfusion. There was no significant difference between the results of RCV estimations using these two methods. Our study demonstrates that biotin labeling is an effective method for determining RCV in preterm infants. The RCV represents the total volume of red cells in the circulation. It has been suggested that the RCV is a better guide to red cell transfusion requirements than Hb concentration (l-3), which has been shown to be a poor predictor of benefit from blood transfusion (4-6). After acute blood loss and in anemia of prematurity, the Hb concentration is poorly correlated with RCV; some infants have a very low RCV, yet maintain an adequate Hb concentration (1, 2, 7). RCV may also be a more rational physiologic indicator than Hb concentration of the oxygen carrying capacity of the blood in the whole circulation (3). Low RCV at birth is associated with birth asphyxia (8, 9), increasing severity of hyaline membrane disease (9, lo), and increased mortality (8, 10). RCV estimation has become a vital investigation in adults with polycythemias, some anemias, and the assessment of erythropoiesis (1 1).Previously described methods for determining RCV include both techniques using the dilution principle after labeling of red cells with a tracer and indirect methods, which give a calculated RCV derived from plasma volume and Hct. Radioisotopes as tracers (1 1 iably to overestimate plasma volume. Accurate calculation of RCV from plasma volume requires not only accurate plasma volume estimation but also a knowledge of the total body Hct. Although correction factors allow for the difference between venous and total body Hct (14, 15, 16), they are of quite unknown reliability in sick infants. RCV can be estimated using dilution of autologous HbF at the time of a blood transfusion (2, 17). This is reliable provided that HbF estimation is accurate (e.g. alkali denaturation technique) (2) and at least 20% of the Hb in the circulation before transfusion is fetal. This technique cannot be used without a donor blood transfusion.A new method has recently been described for determination of RCV in adults. Biotin is used to label autologous red cells, and their dilution is quantitated in a fluorescence-activated cell sorter using the fluorescein-streptavidin reaction (17). Biotin is not toxic in infants, even in pharmacologic doses (1 8).We report here results...
