Methods: This study was conducted on pregnant women with the pregnancy age of > 30 weeks whose fetus was suspected of hydronephrosis. The study participants were collected via the consecutive sampling method. The HI, pelvic AP diameter, and parenchymal thickness were measured at the baseline and 1, 6, and 12 months after delivery using ultrasound. According to the study design, the study participants were divided into three groups. Group A consisted of cases with decreased HI and higher hydronephrosis severity. Group B was composed of subjects with relatively constant HI, and group C entailed individuals with increased HI and lower hydronephrosis severity. All of the study measurements and analyses were performed on the three study groups. Results: The results revealed a negative association between HI and pelvic AP diameter but a positive association with parenchymal thickness. On the other hand, HI showed a significant correlation with parenchymal thickness in the diagnosis and prognostic assessment of fetal hydronephrosis. Conclusion: The HI correlated with parenchymal thickness and pelvic AP diameter scores in all follow-up stages. Accordingly, HI can be concluded to be a good alternative to parenchymal thickness or pelvic AP diameter as a grading factor for hydronephrosis. It is suggested to perform further studies to carefully assess the efficiency of HI in the diagnosis, prognosis, and clinical outcome of hydronephrosis.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"17 1","pages":"24-30"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86860081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we evaluated the resuscitation process of preterm neonates and analyzed the impact of different risk factors on the level of resuscitation required in the patients.Methods: This cross-sectional descriptive study was conducted on inborn preterm infants with a birth weight of < 1500 g during one year. Moreover, the present study evaluated the resuscitation process of the delivery room and analyzed the association of maternal-neonatal risk factors and requirement for different levels of resuscitation.Results: In the present study, 193 preterm neonates were evaluated. In addition, 82 (42.5%) and 110 (57%) patients were female and male, respectively. The mean values of gestational age and birth weight of the patients were 29.9±2.4 weeks and 1191.6±265.2 g, respectively. The mode of delivery in 159 (82.4%) patients was cesarean section.In the assessment of different levels of resuscitation, 84 (43.5%), 35 (18.1%), 54 (28%), 10 (5.2%), 10 (5.2%), and 9 (4.7%) neonates needed initial steps, free flow of oxygen, positive pressure ventilation, endotracheal intubation, chest compression, and drug administration, respectively. The rate of neonatal mortality was 23.8% (n=46), and hypoxic-ischemic encephalopathy was recorded in 10 (21.7%) subjects. In the evaluation of mothers, 117 (60.6%) subjects had medical problems during pregnancy. The most common problem was preeclampsia in 44 (22.8%) mothers. The lower birth weight (P<0.001), gestational age (P<0.001), Apgar score (P<0.001), and longer duration of resuscitation had a significant effect on the needed level of resuscitation in neonates.Conclusion: According to the obtained results, it was shown that premature neonates needed more advanced resuscitation. Therefore, improving the quality of care for mothers and neonates is necessary to obtain better outcomes. Regarding the need for noninvasive positive pressure ventilation was the second most frequent intervention, the proper use of equipment is necessary for the prevention of advanced resuscitation.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"47 1","pages":"57-63"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81560623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study compared the number of nucleated red blood cells (NRBCs) in newborns with and without IVH.Methods: This cross-sectional study was carried out on 109 VLBW neonates who were referred to the Neonatal Intensive Care Unit (NICU) Department of Ghaem Hospital in Mashhad, Iran. They were investigated to evaluate the predictive value of cord NRBC in the diagnosis of IVH. To this end, 77 neonates who had normal brain ultrasonographywere assigned to the control group and 32 newborns with IVH were allocated to the case group. The percentage of NRBC per 100 white blood cells was determined by a blood sample. These neonates underwent brain ultrasonography3-5 days after the birth; thereafter, mean NRBC/100 WBC and the absolute number of NRBC swere compared in both groups.Results: In the current study, the mean scores of NRBC/100 WBC and the absolute number of NRBCs in neonates with IVH were obtained as 15.19 and 2272.38/μl. In the group without IVH, these values were reported as 40.95% and 5459.17/μl, respectively (P>0.05). Based on receiver operating characteristic (ROC) curve, the NRBC value does not have a diagnostic value in predicting the incidence of IVH.Conclusion: As illustrated by the obtained results, the number of absolute NRBCs and the percentage of NRBC/100 WBC cannot help to predict the probability of neonatal IVH.

However, procalcitonin (PCT) and other inflammatory markers have recently been considered as sensitive markers for the early detection of neonatal sepsis. Therefore, the present study aimed to determine the diagnostic value of PCT in the early detection of neonatal sepsis and compare it with C-reactive protein (CRP) and white blood cells count.Methods: This case-control study was conducted on 40 neonates who were divided into two groups. The case or sepsis group consisted of 18 neonates with the clinical symptoms of sepsis and positive culture. On the other hand, the control group contained 22 healthy neonates with negative culture. Demographic characteristic of all the participants was recorded during the clinical follow-up. Moreover, blood samples were collected from each neonate for hematological analysis, blood culture, serum CRP measurement, and PCT analysis. Finally, all the collected data were statistically analyzed in SPSS software (version 17).Results: Based on the findings, the mean value of the procalcitonin level was significantly higher in the sepsis group (866.60±480.51 pg/ml), compared with that of the control group (P<0.001). Moreover, the CRP was positive in 66.7% of sepsis patients and 22.7% of the control group (P=0.006). The procalcitonin level shows higher sensitivity (94%) than CRP (66%) with the same specificity but a higher positive and negative predictive value.Conclusion: Procalcitonin level was elevated in neonates with sepsis in comparison to normal neonates and it is more sensitive than CRP. The PCT could be used as a routine test for the early diagnosis of neonatal sepsis which also leads to a reduction in the use of antibiotics.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"17 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76555018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first week of life, some preterm infants may have grade 1 IVH extending to severe (grade 3 or 4) IVH by transfusion one or more units. Several previous studies have found that blood and blood product transfusions lead to adverse clinical outcomes in neonates. Therefore, this study aimed to explore the relationship between Red blood cell (RBC) transfusion and extension of IVH in preterm infants.Methods: For the purposes of the study, an observational retrospective case-control design was utilized. Moreover, all the neonates with grade 1 IVH in our referral hospital were identified in the past 5 years. Afterward, the subjects with extended IVH were compared with those who had resolved IVH.Results: In total, 1050, 36, and 24 neonates were diagnosed with grade 1, grade 3, and grade 4 IVH, respectively. The mean values of the birth weight of extended IVH and resolved IVH groups were 1285±615 g and 1361±348 g, respectively (P=0.05). Moreover, extended IVH and resolved IVH groups were 29±3 weeks and 30±2 weeks premature, respectively (P=0.36). The low 5-minute Apgar scores of the extended IVH and resolved IVH groups were 5±2 and 7±2, respectively (P=0.000). In addition, the low cord pH of the extended IVH and resolved IVH groups were 7.29±0.1 and 7.37±0.1, respectively (P=0.005). Administration of packed RBC transfusion before and on the day of the diagnosis of grade 1 IVH had the most significant relationship with the extension of IVH (IR, 10.602; 95% CI, 2.81-39.92). The obtained results confirmed that criteria to order the transfusions were similar in both groups, based on which they did not have any proportion of the transfusions of compliance with the guidelines.Conclusion: Based on the results, there was a great association between restrictive RBC transfusion and extension of a low-grade IVH into a higher grade (3 or 4) IVH. However, the statistical explanation is unclear and more studies are needed to discover the causality of this relationship.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"13 1","pages":"92-99"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77945264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
