RESUMO
ABSTRACT Purpose: To determine the predictive value of maternal White Blood Cells (WBC), neutrophils, and C-Reactive Protein (CRP) for diagnosing Histological Chorioamnionitis (HCA) among women with Preterm Premature Rupture of Membranes (PPROM) who underwent cervical cerclage. Methods: A retrospective cross-sectional study was conducted among women with singleton pregnancy and PPROM, who underwent cervical cerclage during 2018-2020. Results: A total of 55 eligible women were included in the final analysis, including 36 (61.02%) cases with HCA and 19 (38.98%) without HCA. Women with HCA had higher WBC count (12.31 ± 2.80) × 109/L and neutrophil count (9.67 ± 2.90)×109/L than those without HCA (10.35 ± 2.53) × 109/L and 7.82 ± 2.82 × 109/L, respectively) (both p < 0.05). The cut-off value of WBC count at 10.15×109/L was found to be the most effective in identifying HCA, with an Area Under Curve (AUC) of 0.707 (95% CI: 0.56-0.86; p = 0.012), sensitivity of 86.11%, specificity of 57.90%, Positive Predictive Value (PPV) of 79.49%, Negative Predictive Value (NPV) of 68.75%, and Youden index of 0.44. The combination of WBC + neutrophil had a slightly higher (AUC = 0.711, 95% CI: 0.57-0.86; p = 0.011), specificity (68.42%), and PPV (81.25%), but lower sensitivity (72.22%), than the WBC count alone. A cut-off value of neutrophil at 7.46 × 109/L was effective in identifying HCA, with an AUC of 0.689 (95% CI: 0.53-0.84; p = 0.022). Discussion: Combination use of WBC+neutrophil was found to be the most accurate predictor of HCA among women with PPROM after surgery of cervical cerclage.
RESUMO
ABSTRACT Background: Previous studies showed consistent results for associations between circulating concentrations of vitamin D and risk of antenatal, postnatal depression. Methods: Articles published in English before November 2020 were searched in databases as follows: PubMed, EMBASE, Web of Science, Medline, Google Scholar and Cochrane. These articles explored associations between circulating concentrations of vitamin D and risk of antenatal, postnatal depression.The present meta-analysis was conducted using STATA 12.0 software. Odds ratios (ORs) and 95% confidence intervals (CIs) extracted from included studies were computed using a random effects model or a fixed effects model according to heterogeneities between included studies. Q test and I2 were used to explore heterogeneities between included studies. Results: 7 cohort studies (including 1567 depression cases and 5254 controls) and 3 case-control studies (including 995 depression cases and 1265 controls) were included in the present study. The study showed that low circulating levels of 25-hydroxy (OH) vitamin D is significantly associated with a higher risk of antenatal and postnatal depression (OR = 1.02, 95% CI 1.01 to 1.04, I2 = 90.7%, p < 0.001). Conclusion: Our results have shown that the low level of vitamin D may be an adverse factor of antenatal and postnatal depression.
