cervical Consistency Index and risk of cesarean delivery after induction of labor at term
Ultrasound in Obstetrics & Gynecology, 2019Co-Authors: Federico Migliorelli, Nuria Banos, Claudia Rueda, Martina Aida Angeles, David E Posadas, E Gratacos, M PalacioAbstract:Objective To evaluate the association between the cervical Consistency Index (CCI) and the risk of Cesarean delivery after planned induction of labor (IOL) at term. Methods This was a prospective observational study of women with a term singleton pregnancy admitted for IOL due to maternal or fetal indication. Ultrasonographic images were obtained before IOL and CCI was calculated offline once recruitment was completed. The main outcome was defined as Cesarean delivery due to failed IOL or arrest of labor. Cesarean deliveries indicated due to maternal or fetal compromise (Van Dillen's grade 1 or 2) were excluded from analysis. Univariate statistical analysis was performed using Fisher's exact test and Student's t-test for categorical and continuous variables, respectively. Multivariate analysis was performed using logistic regression, including CCI and other variables related to the main outcome. Intraclass correlation coefficients were used to estimate intra- and interobserver agreement. Results Of 510 women admitted for IOL during the study period and for whom image quality was adequate, 46 were excluded due to emergency Cesarean delivery leaving 464 pregnancies for analysis. Cesarean section due to failed IOL or arrest of labor was performed in 100/464 (21.6%) pregnancies. The mean CCI of women who underwent Cesarean delivery was not significantly different from that in those who had vaginal delivery after IOL (70.1 ± 12.3% vs 70.0 ± 13.1%; P = 0.94). Multivariate analysis also showed absence of statistical association between CCI and Cesarean delivery for failed IOL or arrest of labor. Intraclass correlation coefficients for intra- and interobserver agreement were 0.81 (95% CI, 0.66-0.89) and 0.86 (95% CI, 0.75-0.92), respectively. Conclusion CCI does not seem to be associated with the risk of Cesarean delivery after IOL. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

mid trimester sonographic cervical Consistency Index to predict spontaneous preterm birth in a low risk population
Ultrasound in Obstetrics & Gynecology, 2018Co-Authors: Nuria Banos, Carla Julia, Federico Migliorelli, E Gratacos, Clara Murillobravo, Alvaro Perezmoreno, Jose Rios, L Valentin, M PalacioAbstract:Objectives: To investigate the effectiveness of mid-trimester sonographic cervical Consistency Index (CCI) for the prediction of spontaneous preterm birth (sPTB) in low-risk pregnancies and to compare its performance with that of mid-trimester sonographic cervical-length (CL) measurement. Methods: This was a prospective cohort study of women with a singleton pregnancy examined by ultrasound at 19+0 to 24+6weeks' gestation. All women underwent transvaginal ultrasound examination of the cervix, but CCI and CL were measured, offline, only in women without a risk factor for sPTB. Staff and participants were blinded to CL and CCI results. CCI was obtained by calculating the ratio between the anteroposterior diameter of the uterine cervix at maximum compression and at rest. The primary outcome was prediction of sPTB before 37+0weeks. Receiver-operating characteristics (ROC) curves were produced and sensitivity and specificity were calculated for the optimal cut-off based on the ROC curve and for the 1st, 5th and 10th centiles of CCI and CL. Intraclass correlation coefficients (ICC) and Bland-Altman plots were used to estimate intra- and interobserver agreement and reliability for measurement of CCI and CL. Results: Of the 749 women who underwent ultrasound examination of the cervix, 532 were included for analysis. The rates of sPTB before 37+0 and before 34+0weeks were 4.1% (22/532) and 1.3% (7/532), respectively. The rates of short cervix 0.90 both for CCI and CL, while interobserver ICC was 0.89 for CCI and 0.90 for CL. Conclusions: Second-trimester CCI is a better predictor of sPTB <37weeks in low-risk pregnancies than is CL. External validation is needed as well as studies assessing the value of CCI as a screening tool in unselected and high-risk populations. (Less)

op08 03 tranvaginal ultrasonographic measurement of cervical Consistency Index cci throughout gestation in twin pregnancy
Ultrasound in Obstetrics & Gynecology, 2012Co-Authors: M Parrasaavedra, E Gratacos, Anna Gonce, N Masoller, M PalacioAbstract:Objectives: Uterine cervix changes shortened and softened during pregnancy. Although cervical length has been studied and known sufficiently as a predictor of preterm birth, cervical Consistency has still not been studied and understood well because its measurement like elastography requires special equipment and instrument. This study aimed the difinition of the new simple Index to evaluate cervical Consistency using transvaginal B-mode ultrasonography. Methods: This study was a prospective study conducted from September 2011 to March 2012. Manual examination and transvaginal ultrasonography of the uterin cervix in regular checkups at our clinic from sixty-four singleton pregnant women without any complications were allocated for the study. ‘‘Cervival deformityConsistency Index (DCI)’’ was defined as follows: cervival length in trace length (L) and thickness (D) were measured by tranvaginal B-mode ultrasonography; the cervix was consecutively compressed by the probe at the side and then the trace length (L′) and the thickness (D′) were measured; DCI was given as (L/D)/(L′/D′) ×100. DCI was compared to manual examination and studied about the relationship to premature labor. Results: DCI was smaller when cervix was manually diagnosed soft than when firm. DCI showed significantly smaller value between 28th and 32nd week among the women with premature labor than among ones following normal course (54.2 ± 13.1 vs. 65.1 ± 12.6; P < 0.01). Conclusions: DCI was demonstrated as an objective value of cervical Consistency. As DCI of premature labor women showed smaller values, simple evaluation of cervical Consistency as important as uterine contraction has got available to be concerned. DCI is simple and easy to obtain and is therefore to be discussed about its availability with more data accumulated.

pasting properties of non waxy rice starch hydrocolloid mixtures
Starch-starke, 2006Co-Authors: Ji-young Song, Ji Young Kwon, Jung-do Choi, Malshick ShinAbstract:The swelling and pasting properties of non-waxy rice starch-hydrocolloid mixtures were investigated using commercial and laboratory-generated hydrocolloids. The swelling power of the rice starch-hydrocolloid mixtures was generally depressed at low concentration of hydrocolloids (0–0.05%), but increased directly with increasing hydrocolloid concentrations (0.05–0.1%). In gellan gum dispersion, the swelling power at 100°C was higher than that of control. The rice starch-hydrocolloids mixtures showed shear-thinning flow behavior (n = 0.26–0.49). Hydrocolloids except the exopolysaccharide from S. chungbukensis (EPS-CB) increased apparent viscosity and Consistency Index (K) of rice starch dispersions, but decreased the n value. Hydrocolloids enhanced the trough and final viscosity of rice starch dispersions but EPS-CB reduced the viscosity of rice starch pastes. Hydrocolloids lowered peak viscosity but addition of guar gum resulted in high peak viscosity, apparent viscosity, and Consistency Index of rice starch dispersions. Total setback viscosity appeared to be not affected by hydrocolloids at low concentration (0.05%). The hot and cold paste of the starch-gellan gum mixture exhibited the highest viscosity values in the Brookfield viscometer.

mid trimester cervical Consistency Index and cervical length to predict spontaneous preterm birth in a high risk population
American Journal of Perinatology Reports, 2018Co-Authors: Nuria Banos, Carla Julia, Nuria Lorente, Silvia Ferrero, Teresa Cobo, Eduard Gratacos, Montse PalacioAbstract:Background Short cervical length (CL) has not been shown to be adequate as a single predictor of spontaneous preterm birth (sPTB) in high-risk pregnancies. Objective The objective of this study was to evaluate the performance of the mid-trimester cervical Consistency Index (CCI) to predict sPTB in a cohort of high-risk pregnancies and to compare the results with those obtained with the CL. Study Design Prospective cohort study including high-risk singleton pregnancies between 19+0 and 24+6 weeks. The ratio between the anteroposterior diameter of the uterine cervix at maximum compression and at rest was calculated offline to obtain the CCI. Results Eighty-two high sPTB risk women were included. CCI (%) was significantly reduced in women who delivered Conclusion CCI performed better than sonographic CL to predict sPTB. Due to the limited predictive capacity of these two measurements, other tools are still needed to better identify women at increased risk.

predicting somatic cell count standard violations based on herd s bulk tank somatic cell count part ii Consistency Index
Journal of Dairy Science, 2008Co-Authors: J M Lukas, J K Reneau, Claudia A Munozzanzi, M L KinselAbstract:The present study examines the capability of 1,501 herds in the Upper Midwest and the performance of statistical process control charts and indices as a way of monitoring and controlling milk quality on the farm. For 24 mo, daily or every other day bulk tank somatic cell count (SCC) data were collected. Consistency indices for 5 different SCC standards were developed. The indices calculate the maximum variation allowed to meet a desired SCC level at a given mean bulk tank SCC and were used to identify herds not capable of meeting a specific SCC standard. Consistency Index method was compared with a test identifying future bulk tank SCC standard violators based on herds' past violations. The performance of the Consistency Index test and the past violation method was evaluated by logistic regression. The comparison focused on detection probability and certainty associated with a result. For the 5 SCC levels, detection probability and certainty associated with a result ranged from 51 to 98%. Detection probability of all violators and certainty associated with a negative result was greater for the Consistency Index across all 5 SCC levels (by 0.7 to 7.4% and 2.1 to 5.1%, respectively). Control charts were plotted and monthly Consistency indices calculated for individual farms. Charts in combination with the Consistency indices would warn from 66 to 80% of the herds about an upcoming violation within 30 d before it occurred. They offer a proactive approach to maintaining consistently high milk quality. By assessing process capability and distinguishing between significant changes and random variation in bulk tank SCC, tools presented in this article encourage fact-based decisions in dairy farm milk quality management.
