Aim: The study aimed to identify predictive risk factor to identify high‐stage histological chorioamnionitis (HCA) in pregnancies with cervical incompetence (CIC). Methods: A retrospective cohort study was conducted by including 116 pregnant women with cervical incompetence that required prophylactical and therapeutical cerclage. The histopathology examination on placenta was conducted with informed patient consent. All the cases included in this study were divided based on the severity degree of HCA. The demographic characteristic and the parameters related to maternal and fetal outcome were all analyzed. Besides, perioperative parameters of cerclage, including cervical length, cervical morphology, and laboratory indexes were also compared between two groups. Univariate and multivariate logistic regression analysis were used to determine the risk factor of severe chorioamnionitis. Results: Severe HCA was significantly associated with cervical morphology, cerclage indication, cerclage type, and cervical length measured via ultrasound and vaginal examination. After adjusted for confounders, V‐type funneling and short cervix was indicated as independent risk factors of severe HCA by multivariate logistic regression analysis, respectively. Conclusions: V‐type funneling and short cervix may indicate the elevated risk of high‐stage HCA. Due to the negative outcomes related with high‐stage HCA, appropriate prenatal treatment would improve the pregnancy outcomes in cerclaged population. To facilitate postpartum treatment, placental histological examination should be routinely recommended to identify the high‐stage HCA, especially in high risk pregnancies. [ABSTRACT FROM AUTHOR]

Aims To detect specific oculomotor deficits in preclinical stage of spinocerebellar ataxia type 3 ( SCA3) and evaluate whether these abnormalities prove useful as potential biomarkers of disease progression. Methods A Chinese cohort of 56 patients with SCA3, including 12 preclinical carriers of SCA3 (pre- SCA3) and 44 manifest SCA3, and 26 healthy control individuals were recruited. We performed a detailed investigation on central oculomotor performance including fixation, gaze, smooth pursuit, prosaccade, and antisaccade using video-oculography. Results Common oculomotor features of pre- SCA3 included square-wave jerk during central fixation and gaze holding, impaired vertical smooth pursuit, slow upward saccade, and increased antisaccade error rate. In our SCA3 cohort, all oculomotor parameters were correlated with the score of the Scale for the Assessment and Rating of Ataxia, whilst some of them were correlated with disease duration. Conclusion This study showed that a series of neuropathological changes reflected by oculomotor abnormalities appeared preferentially in preclinical stage of SCA3. Accordingly, objective oculomotor preclinical signs may be useful to detect the optimum time-point for therapeutic interventions in future clinical trials of SCA3. Larger and longitudinal data are warranted to confirm our results. [ABSTRACT FROM AUTHOR]

The aim of this study was to build a new nomogram score for predicting surgery-related pressure ulcers ( SRPU) in cardiovascular surgical patients. We performed a prospective cohort study among consecutive patients with cardiovascular surgery between January 2015 and December 2015. Univariate and multivariate logistic regression was used to analyse the risk factors for SRPU. A nomogram-predicting model was built based on the logistic regression model. Then, calibration and discrimination were tested. A total of 149 patients with cardiovascular surgery were included in the study. Thirty-seven patients developed SRPUs, with an incidence rate of 24·8% (95% CI: 18·1-32·6%). The logistic regression model for predicting SRPU with four risk factors was Logit( P) = (1·861 × VDH, OR 2·174 × CAD, OR 1·747 × TAA) − 0·029 × weight + 0·005 × surgery duration + 1·241 × perioperative corticosteroids administration ( P = 0·003, R2 = 0·1181). The goodness-of-fit test (Pearson χ2 = 150·69, P = 0·217) indicated acceptable calibration, and the C-index (0·725) indicated moderate discrimination. When the probability cut-off is 0·25 (total score 12), the nomogram model has the best sensitivity and specificity in predicting SRPU. We established a new nomogram model that can provide an individual prediction of SRPU in cardiovascular surgical patients. When the probability is more than 0·25 (total score 12), the cardiovascular surgery patients should be considered at high-risk. [ABSTRACT FROM AUTHOR]
