Patient-reported outcome measures which assess body image in urogynaecology patients: a systematic review.

AIM: Urogynaecological conditions can have a significant impact on body image. Patient-reported outcome measures (PROMs) are widely used in urogynaecology to assess symptoms and their impact on quality of life. This systematic review aimed to identify currently available PROMs used to assess body image within a urogynaecological population and to identify the most psychometrically robust and appropriate PROM tools to use in this context. METHODS: Ovid Medline, AMED, CINAHL, Cochrane Collaboration, EMBASE and Web of Science databases were searched from January 1966 to November 2018 to identify studies that had administered a PROM to assess body image to patients diagnosed with a urogynaecological condition. The information extracted and critically appraised included study setting, PROM instrument used and the reported psychometric properties of the PROM. RESULTS: Seventeen studies were included from 3207 screened articles. Seven different PROMs used to assess body image in a urogynaecological population were identified. Two of these PROMs (Genital Self-Image Scale-20 and Body Image in Pelvic Organ Prolapse questionnaire) had good psychometric evidence for use, but this was only in the context of women with prolapse. Evidence for validity and reliability was limited for the other five PROMs identified. CONCLUSION: Further development and psychometric testing of PROMs to assess body image in urogynaecology, for both research purposes and clinical practice, are required. Further research is also required to investigate the relationship between body image and urogynaecological symptomatology, and developing valid, reliable and functional PROMs will be integral to this.

Cell free hemoglobin in the fetoplacental circulation: a novel cause of fetal growth restriction?

Cell free hemoglobin impairs vascular function and blood flow in adult cardiovascular disease. In this study, we investigated the hypothesis that free fetal hemoglobin (fHbF) compromises vascular integrity and function in the fetoplacental circulation, contributing to the increased vascular resistance associated with fetal growth restriction (FGR). Women with normal and FGR pregnancies were recruited and their placentas collected freshly postpartum. FGR fetal capillaries showed evidence of erythrocyte vascular packing and extravasation. Fetal cord blood fHbF levels were higher in FGR than in normal pregnancies ( P < 0.05) and the elevation of fHbF in relation to heme oxygenase-1 suggests a failure of expected catabolic compensation, which occurs in adults. During ex vivo placental perfusion, pathophysiological fHbF concentrations significantly increased fetal-side microcirculatory resistance ( P < 0.05). fHbF sequestered NO in acute and chronic exposure models ( P < 0.001), and fHbF-primed placental endothelial cells developed a proinflammatory phenotype, demonstrated by activation of NF-κB pathway, generation of IL-1α and TNF-α (both P < 0.05), uncontrolled angiogenesis, and disruption of endothelial cell flow alignment. Elevated fHbF contributes to increased fetoplacental vascular resistance and impaired endothelial protection. This unrecognized mechanism for fetal compromise offers a novel insight into FGR as well as a potential explanation for associated poor fetal outcomes such as fetal demise and stillbirth.-Brook, A., Hoaksey, A., Gurung, R., Yoong, E.
