An psychoeducation programme based on self-efficacy theory to improve experience of natural birth for primigravid women: Study protocol for a randomised controlled trial.

AIM AND OBJECTIVES: To present a study protocol for estimating the feasibility, effectiveness and safety of an individual (five sessions), group (one session) and face-to-face psychoeducation programme based on self-efficacy theory to improve childbirth experience of primigravid women. BACKGROUND: In present China, fertility rates are falling and ageing is accelerating. How to improve the fertility level of childbearing women is of great significance. However, about 10%-20% of women have negative childbirth experience after birth, which seriously affects maternal and child health and family functions, and even fertility desires and intentions in the future. Nevertheless, due to the lack of a series of well-designed randomised controlled trials(RCTs), there is no specific methodology to guide the most effective intervention for primigravid women. In this regard, based on Bandura's self-efficacy theory, an intervention programme to promote a positive childbirth experience for primigravid women has been designed and will be evaluated to determine its impact on primigravid women. DESIGN: A non-blinded randomised controlled trial. METHODS: We report the study protocol for this randomised controlled trial based on the SPIRIT2013 statement. A total of 238 eligible primigravid women will be randomly divided into the control group (n = 119) or the intervention group (n = 119). The control group will receive care as usual, that is, six routine prenatal examinations. In addition to the routine examinations, the intervention group will also receive six face-to-face interventions. Baseline assessment will occur at about 24th week of gestation and follow up at 37th weeks of gestation, intrapartum, 1-3 days postpartum and 42 days postpartum. The primary outcomes are childbirth experience, childbirth self-efficacy; others are fear of childbirth, labour control, labour pain and labour satisfaction. IMPACT: From the perspective of clinical work, this protocol provides practical guidance for cultivating the positive childbirth experience of the primigravid women. From the perspective of sociology, the positive experience and emotion of primigravid women can improve the fertility intention of women of childbearing age, which is relatively conducive to optimising Chinese demographic structure and reducing the pressure of ageing population in the long term.

Multi-scale hyperspectral imaging of cervical neoplasia.

PURPOSE: This preliminary study aimed at investigating the feasibility and effective of multi-scale hyperspectral imaging in detecting cervical neoplasia at both tissue and cellular levels. METHODS: In this paper, we describe a noninvasive diagnosis method with a hyperspectral imager for detection and location of cervical intraepithelial neoplasia (CIN) at multiple scales. At the macroscopic level, the hyperspectral imager was applied to capture the reflectance images of the entire cervix in vivo at a series of wavelengths. At the microscopic level, the hyperspectral imager was coupled with a microscope to collect the transmittance images of the pathological slide. The collected image data were calibrated. A wide-gap second derivative analysis was applied to differentiate CIN from other types of tissue. RESULTS: At both macroscopic and microscopic levels, hyperspectral imaging analysis results were consistent with those of histopathological analysis, indicating the technical feasibility of multi-scale hyperspectral imaging for cervical neoplasia detection with accuracy and efficacy. CONCLUSION: We propose a multi-scale hyperspectral imaging method for noninvasive detection of cervical neoplasia. Comparison of the imaging results with those of gold standard histologic measurements demonstrates that the hyperspectral diagnostic imaging system can distinguish CIN at both tissue and cellular levels.

Evaluation of the clinical application of the Postpartum Depression Predictors Inventory-Revised for postpartum women in China.

AIM: This study was designed to assess the clinical applicability of the Postpartum Depression Predictors Inventory-Revised (PDPI-R) during the 1st month following delivery among women in China and to survey the prevalence of postpartum depression (PPD)-related risk factors included in the PDPI-R in this population. METHODS: This was a cross-sectional study which recruited 447 women from the People's Liberation Army Hospital in Hefei of Anhui province. All participants completed the Chinese version of the PDPI-R (PDPI-R-C) and the Chinese version of the Edinburgh Postnatal Depression Scale (C-EPDS) within 1 month of delivery. The predictive ability of the PDPI-R was then evaluated through receiver operating characteristic (ROC) curve analyses. RESULTS: The PDPI-R-C was able to accurately predict 73.2% of PPD cases (area under the ROC curve = 0.732; 95% CI 0.69-0.78) using a cut-off score of 5.5, as defined by a C-EPDS score of ≥10 (sensitivity = 62.8%; specificity = 73.5%; positive predictive value = 74.5%; negative predictive value = 61.5%). All 13 risk factors in the PDPI-R-C other than socioeconomic status and marital status were associated with the risk of PPD. CONCLUSIONS: The PDPI-R-C was found to be an effective and easy-to-implement tool that has promise as a means of screening for PPD in Chinese populations.
