Supporting the Decision Making of Children With Cancer: A Meta-synthesis.

Background: Recently, awareness of children's decision making has increased in an effort to enhance palliative care. However, the conceptual framework for decision making among children with cancer remains unclear. Aims: We clarified the decision-making process of children with cancer regarding their care, treatment, and support from family and health care professionals, and identified their needs and preferences. Design: We used metaethnography to conduct a metasynthesis of relevant studies. Data sources: We searched PubMed, EMBASE, PsycINFO, MEDLINE, and CINAHL. This report was prepared in accordance with the PRISMA statement. Results: Of the 7,237 retrieved studies, 27 met our inclusion criteria. Four themes emerged that reflected the decision-making process of children with cancer: (a) facing changes brought about by a health threat, (b) preparing for action, (c) asserting one's choice, and (d) internal and external influences. Conclusion: Children with cancer initially undergo a decision-making process. Respecting children's preferences, values, and emotions may help build trusting relationships and promote their decision-making capability. Future research should focus on children's emotions, cognition, development, and interactions with parents and health care professionals.

Diagnostic Accuracy of Ultrasound Scanning for Prenatal Microcephaly in the context of Zika Virus Infection: A Systematic Review and Meta-analysis.

To assess the accuracy of ultrasound measurements of fetal biometric parameters for prenatal diagnosis of microcephaly in the context of Zika virus (ZIKV) infection, we searched bibliographic databases for studies published until March 3rd, 2016. We extracted the numbers of true positives, false positives, true negatives, and false negatives and performed a meta-analysis to estimate group sensitivity and specificity. Predictive values for ZIKV-infected pregnancies were extrapolated from those obtained for pregnancies unrelated to ZIKV. Of 111 eligible full texts, nine studies met our inclusion criteria. Pooled estimates from two studies showed that at 3, 4 and 5 standard deviations (SDs)

Zika virus infection in pregnancy: a systematic review of disease course and complications.

OBJECTIVES: To characterize maternal Zika virus (ZIKV) infection and complement the evidence base for the WHO interim guidance on pregnancy management in the context of ZIKV infection. METHODS: We searched the relevant database from inception until March 2016. Two review authors independently screened and assessed full texts of eligible reports and extracted data from relevant studies. The quality of studies was assessed using the Newcastle-Ottawa Scale (NOS) and the National Institute of Health (NIH) tool for observational studies and case series/reports, respectively. RESULTS: Among 142 eligible full-text articles, 18 met the inclusion criteria (13 case series/reports and five cohort studies). Common symptoms among pregnant women with suspected/confirmed ZIKV infection were fever, rash, and arthralgia. One case of Guillain-Barré syndrome was reported among ZIKV-infected mothers, no other case of severe maternal morbidity or mortality reported. Complications reported in association with maternal ZIKV infection included a broad range of fetal and newborn neurological and ocular abnormalities; fetal growth restriction, stillbirth, and perinatal death. Microcephaly was the primary neurological complication reported in eight studies, with an incidence of about 1% among newborns of ZIKV infected women in one study. CONCLUSION: Given the extensive and variable fetal and newborn presentations/complications associated with prenatal ZIKV infection, and the dearth of information provided, knowledge gaps are evident. Further research and comprehensive reporting may provide a better understanding of ZIKV infection in pregnancy and attendant maternal/fetal complications. This knowledge could inform the creation of effective and evidence-based strategies, guidelines and recommendations aimed at the management of maternal ZIKV infection. Adherence to current best practice guidelines for prenatal care among health providers is encouraged, in the context of maternal ZIKV infection.
