RESUMEN

BACKGROUND: The purpose of this study was to improve diagnostic and therapeutic standards by examining the clinical features, treatment, and prognosis of fetal meconium peritonitis (FMP), as well as the diagnostic efficacy of ultrasound for FMP. METHODS: The clinical data of 41 infants and pregnant women diagnosed with meconium peritonitis (MP) and treated at the Fujian Maternal and Child Health Hospital from January 2013 to January 2020 were analyzed retrospectively. Clinical data, imaging data, complications, treatment strategies, pregnancy outcomes, neonatal prognoses, and follow-up outcomes were all analyzed. RESULTS: The MP prenatal diagnosis rate was 56.1% (23/41), the neonatal surgery rate was 53.7% (22/41), and the survival rate was 85.4% (35/41). Intraperitoneal calcification (23 pregnant women, 56.1%), intestinal dilatation (13 pregnant women, 31.7%), peritoneal effusion (22 pregnant women, 53.7%), intraperitoneal pseudocyst (7 pregnant women, 17.1%), and polyhydramnios were diagnosed via prenatal ultrasound (18 pregnant women, 43.9%). Twenty-two pregnant women were assigned to the surgical treatment (operation) group, while 18 were assigned to the conservative treatment group. In the operation group, there were 9 cases of ileal atresia (40.9%), 7 cases of jejunal atresia (31.8%), 2 cases of atresia at the jejunum-ileum junction (9.1%), 2 cases of ileal perforation (9.1%), 1 case of ileal necrosis (4.5%), and 1 case of adhesive obstruction (4.5%). There was no statistically significant difference (p > .05) in the occurrence of various prenatal ultrasound findings by etiology. CONCLUSION: Multiple prenatal ultrasound markers have been identified for MP. To improve the efficacy of newborn treatment for FMP and reduce neonatal mortality, dynamic monitoring of ultrasound image alterations and strengthened integrated perinatal management are necessary.

RESUMEN

The purpose of this paper is to explore the relationship between serum thyroid-stimulating hormone (TSH) levels and adverse pregnancy outcomes in advanced maternal age. A total of 97 elderly parturient women who were treated in our hospital from June 2020 to March 2021 are included in this study. According to the TSH level, the parturient women are divided into three groups, including A (<0.25 µIU/ml), B (>4.00 µIU/ml), and C (0.25-4.00 µIU/ml) groups. The clinical data of all parturients are collected and sorted out. The serum levels of TSH, free triiodothyronine (FT3), and free thyroxine (FT4) are measured by chemiluminescence immunoassay. The levels of immunoglobulin (Ig) A, IgG, and IgM are determined by immunoturbidimetry. The incidence of adverse pregnancy outcomes is analyzed. The birth weight and Apgar score of newborns in the three groups are compared. The TSH level in group A is significantly lower than that in groups B and C, but the levels of FT3 and FT4 in group A are notably higher than those in groups B and C (P < 0.05). The levels of IgA, IgG, and IgM in group A are significantly higher than those in groups B and C (P < 0.05). The incidence of adverse pregnancy outcomes in group C is 2.38%, which is obviously lower than the 20.00% in group A and 17.14% in group B (P < 0.05). The birth weight and Apgar score of infants in group A and group B are significantly lower than those in group C (P < 0.05). TSH has a great influence on the pregnancy outcome in advanced maternal age, which should be paid more attention in clinic.

RESUMEN

BACKGROUND: Histological chorioamnionitis (HCA) is one of the leading causes of spontaneous preterm birth, thus, to identify novel biomarkers for the early diagnosis of HCA is in a great need. OBJECTIVE: To investigate the diagnostic value of maternal peripheral blood platelet-to-white blood cell ratio (PLT/WBC) and platelet (PLT) counts in HCA-related preterm birth. METHODS: A total of 400 patients with preterm birth were enrolled in this study: non-HCA group (n = 193) and HCA group (n = 207), and 87 full-term pregnancies were enrolled as the control. The peripheral blood of the participators was collected, and the neutrophil count, WBC count, platelet count, and levels of C-reactive protein (CRP) and procalcitonin were recorded, and the platelet-to-white blood cell ratio (PLT/WBC) of the participators was calculated. Receiver operating characteristic (ROC) curve has been drawn to show the sensitivity and specificity of PLT/WBC and PLT count for the diagnosis of HCA-related spontaneous preterm birth patients. RESULTS: The neutrophil count, WBC count, and procalcitonin show no significant differences among the three groups, and the PLT count, PLT/WBC, and CRP (P < 0.05) were significantly increased in HCA group compared with non-HCA group; moreover, the area under the curve (AUC) of PLT/WBC, PLT, and CRP was 0.744 (95% confidence interval [CI], 0.6966-0.7922), 0.8095 (95% CI, 0.7676-0.8514), and 0.5730 (95% CI, 0.5173-0.6287), respectively. CONCLUSION: Platelet count and PLT/WBC may become a potential biomarker of HCA-related spontaneous preterm birth.

RESUMEN

OBJECTIVE: To explore the relationship between HBV-DNA load and the offspring vertical transmission of HBV. METHODS: 138 families who had taken the examination between August 2009 and November 2011 but the HBsAg of the housewife was negative, were chosen as research objects. Blood from the couples and sperms from the husbands during pregnancy were followed and collected for detection on related indicators. Cord blood was sampled after delivery for HBVM and HBV-DNA quantification. Those with HBV-DNA load ≥5×10(2) copies/ml were chosen as cases while those <5 × 10(2) copies/ml were formed as controls, respectively. RESULTS: 1) The positive rates of HBV-DNA was 34.8% (48/138)in the neonatal cord blood while the positive rates of cord blood HBsAg and HBeAg were 28.3% (39/138) and 15.2% (21/138) respectively. 2) The positive rate of semen HBV-DNA was 21.0% (29/138) while the positive rates of paternal serum HBV-DNA and HBeAg were 76.8% (106/138) and 42.8% (59/138). 3) Among the positive ones on paternal serum HBV-DNA, paternal serum HBeAg, semen HBV-DNA, items as measures taken for HBV vertical transmission and prevention on the fathers and the first class family histories on HBV appeared to be the risk factors for HBV paternal transmission (P < 0.05). 4) Data from Multivariate analysis showed that positivities on paternal serum HBV-DNA, paternal serum HBeAg and semen HBV-DNA were risk factors for HBV paternal transmission (OR = 5.7, 95%CI:1.1-29.1; OR = 4.2, 95%CI:1.7-10.0; OR = 6.7, 95% CI:2.4-18.9). 5)Dose-response relationships were seen between levels of paternal serum HBV-DNA load and cord blood HBV-DNA load, between levels of paternal serum HBV-DNA load and semen HBV-DNA load, between levels of semen HBV-DNA load and cord blood HBV-DNA load. 6)Results from the analysis on ROC curve showed that paternal serum HBV-DNA load level (10(5) copies/ml)and semen HBV-DNA load level (10(3) copies/ml) were better demarcation points to forecast the occurrence of paternal transmission of HBV, because of the better sensitivity and specificity they had. CONCLUSION: Items as positives on paternal serum HBV-DNA, paternal serum HBeAg and semen HBV-DNA were risk factors for HBV paternal transmission. When paternal serum HBV-DNA load >10(5) copies/ml and semen HBV-DNA load >10(3) copies/ml appeared, the positive rate of HBV paternal transmission would increase.

RESUMEN

OBJECTIVE: To explore the risk factors and the rate of HBV vertical transmission from HBsAg-positive couple to their infant. METHODS: 46 families who had antenatal examination at Fujian Provincial Maternal and Child Health Hospital during August 2010 and November 2011 were chosen as research object. Cord blood was sampled after delivery for HBVM and HBV-DNA quantification. Those with HBV-DNA load ≥ 5 × 10(2) copies/ml were involved in the case group while those having < 5 × 10(2) copies/ml were chosen as controls. RESULTS: The average positive rate of neonatal cord blood HBV-DNA was 45.7% (21/46), while the positive rates of cord blood HBsAg and HBeAg were 34.8% (16/46) and 23.9% (11/46) respectively. The positive rates of maternal serum HBV-DNA and paternal serum HBV-DNA were 52.2% (24/46) and 69.6% (32/46) respectively, with the positive rate of couple serum HBeAg as 39.1% (18/46) and 32.6% (15/46) respectively. Results from univariate analysis showed that hepatitis B surface markers, serum HBeAg-positive, serum HBV-DNA positive, and serum HBV-DNA load of the couples were risk factors to the HBV vertical transmission (χ(2) = 8.731, 8.414, 8.932, 9.663, 10.823, 3.962, 13.638, 36.501; P < 0.05). Data from the multivariate analysis showed that maternal serum HBV-DNA positive and paternal serum HBV-DNA load were risk factors to the HBV vertical transmission[OR = 17.6 (1.3 - 238.4) ; OR = 3.5 (1.6-7.6)]. Serum HBV-DNA loads of the couples were positively correlated with the cord blood HBV-DNA load, while the load levels of the couple's serum HBV-DNA were higher than cord blood HBV-DNA. There appeared dose-response relationship between couple's serum HBV-DNA load level and the cord blood HBV-DNA load level. RESULTS: from the analysis of ROC curve showed that both maternal serum HBV-DNA load level (10(3) copies/ml) and paternal serum HBV-DNA load level (10(4) copies/ml) were demarcation points to better forecast the occurrence of vertical transmission of HBV, because there showed higher sensitivity and specificity for the forecasting process. Neonatal outcomes showed no significant difference between the case group and the control group. The negative conversion rate became 15.0% (3/20) when the HBV-DNA positive infants were followed up for 7 months. CONCLUSION: Both maternal serum HBV-DNA positive and paternal serum HBV-DNA load were risk factors of HBV vertical transmission. When the maternal serum HBV-DNA load appeared > 10(3) copies/ml and paternal serum HBV-DNA load > 10(4) copies/ml, the rate of HBV vertical transmission would increase.
