Comparison of the Percentage of Umbilical Cord Nucleated Red Blood Cells in Preterm Neonates during Vaginal Delivery and Emergency Cesarean Section.

Background: There are insufficient and contradictory reports regarding the effect of delivery method on the rate of umbilical cord Nucleated Red Blood Cell (NRBC). Therefore, the present study aimed to compare the percentages of umbilical cord NRBC in vaginal delivery and emergency cesarean section (C-section) in preterm neonates. Materials and Methods: The present cross-sectional study was performed on mothers with vaginal delivery and C-section, from 2020 to 2021. The samples (n = 221) were preterm neonates selected using the convenience sampling method. The percentages of NRBC in neonates born by natural childbirth and by emergency C-section were measured and compared in this research. A researcher-made checklist, which included maternal and neonatal characteristics and laboratory evaluation, was used as a data collection tool. Results: The statistical population of thisresearch included 93 (42.10%) and 128 (57.90%) neonates born by vaginal delivery and by C-section, respectively.The mean (SD) score of gestational ages at birth was 30.75 (2.81) weeks. The mean (SD) score of umbilical cord NRBC level were estimated at 8.01 (5.93) and 25.64 (22.61) for the neonates born by natural childbirth and by emergency C-section, respectively (t=-8.43, df = 150, p<0.001). Statistically significant differences were observed in the gestational age (t=-3.36, df = 218, p = 0.001), fifth-minute Apgar score (t=-2.32, df = 200, p = 0.021), umbilical cord NRBC (t=-8.43, df = 160, p<0.001), and short-term prognosis (p = 0.032) between the two groups. It was also revealed that the number of NRBCs in the dead neonates was about 1.5 times higher than that in the discharged neonates. Conclusions: Based on the results of the present study, emergency C-section increased the mean of umbilical cord NRBC by three times, compared to that of normal delivery. Since an increase in the NRBC raises the risk of infant death, it is advisable to take steps to maintain the health of children by identifying high-risk neonates through umbilical cord NRBC measurement immediately after delivery and special care.

Etiology, clinical findings and laboratory parameters in neonates with acute bacterial meningitis.

BACKGROUND AND OBJECTIVES: Neonatal meningitis is one of the most important and serious neonatal infections with a high mortality and morbidity rate. The present study aimed to investigate the causes, clinical signs, laboratory parameters and mortality rates in newborns with bacterial meningitis. MATERIALS AND METHODS: This cross-sectional study was performed on 468 neonates aged 2-28 days admitted to NICU in Ghaem Hospital Mashhad, Iran by available sampling method during 2009-2018. Meningitis was confirmed according to positive results of CSF culture and clinical feature. By using researcher-made questionnaire, neonate's individual data including cardiopulmonary resuscitation, the Apgar score of the first and fifth minutes, gestational age, birth weight, clinical symptoms and laboratory data such as ESR, WBC and positive culture of CSF were studied. RESULTS: Among 468 newborn suspected to infection, lumbar Puncture (LP) was performed for 233 cases (50%). Of 233 neonates, 148 neonates (63.5%) had negative results for CSF culture and 85 cases (36.5%) had positive CSF culture. 94% of cases with meningitis were born premature. Blood culture had positive results in 80% of infants with late-onset meningitis and negative in 20%. The most common clinical findings were respiratory symptoms (94%). Klebsiella pneumoniae and Entrobacter aerugenes were the most common microorganisms of meningitis. Gestational disorders were observed in 55.3% of newborns with meningitis. C-Reactive Protein (CRP) of neonates with meningitis was twice higher than normal cases, and leukocytes and proteins in the CSF in neonates with meningitis were higher than healthy ones. Finally, 36% of neonates with meningitis died in our study. For analyzing the relationships between variables, independent t-test was used after controlling the normality, and Chi-square was used for analyzing the relationship of variables with nominal scale. CONCLUSION: The most common pathogens of meningitis were Klebsiella pneumoniae and Enterobacter aerogenes. Respiratory symptoms were the most common clinical signs, and laboratory symptoms included increased CRP, increased leukocytes and proteins in CSF.

Etiology of gastrointestinal bleeding in children referred to pediatric wards of Mashhad hospitals, Iran.

BACKGROUND: Gastrointestinal (GI) bleeding, which has several clinical manifestation and origins, is known as one of the most life-threatening events in children. Several etiologies have been suggested for GI bleeding. OBJECTIVE: To determine the most important causes of GI bleeding in children referred to Ghaem Hospital and Dr. Sheikh Hospital, Mashhad, Iran. METHODS: In this cross-sectional study, after obtaining written informed consent of their parents, 113 patients aging from newborn infants to 18-year-old children with GI bleeding admitted to Ghaem Hospital and Dr. Sheikh hospital were enrolled in this study from June 2012 to June 2014. After performing routine diagnostic and therapeutic procedures, a checklist containing all necessary information including demographic data, clinical history of patients, endoscopy and pathology findings, clinical and preclinical information were collected. The data were then analyzed using Statistical Package for the Social Sciences (SPSS) version 16. RESULTS: Of a total 113 study children, 61 (54%) were male and 52 (46%) were female. The results of this study showed that the most important causes of bleeding in upper GI among all admitted patients were prolapse gastropathy (18.6%), esophagitis (15.9%) and esophageal varices, gastritis, and coagulopathy (7.1% for each). The main causes of lower GI bleeding were polyp (32.5%), chronic nonspecific colitis (20.7%), and proctitis (18.2%). CONCLUSION: Findings of this study indicated that prolapse gastropathy and esophagitis are more prevalent causes of upper GI bleeding. Furthermore, esophageal varices were more common in children older than 13 years. Polyp, chronic nonspecific colitis and proctitis are the most prevalent causes of lower GI bleeding.

Evaluation of anxiety and depression in mothers of children with asthma.

BACKGROUND: Asthma is the most common chronic disease in childhood. Parents have an important role in managing asthma in children. Studies have shown a higher degree of depression and anxiety and lower family performance in mothers of asthmatic children in comparison with the control group. OBJECTIVE: The aim of this study was to evaluate the parenting styles and also depression, anxiety and stress parameters in mothers of children with asthma. METHODS: This case-control study was performed on 45 mothers of 3 to 15 years old asthmatic children in the allergy clinic of Mashhad University of Medical Sciences, Mashhad, Iran, during the years of 2014 to 2016. The control group was 45 mothers of non-asthmatic children who were matched for the age of their children with the case group in the same population. The parenting styles, as well as depression and anxiety of mothers were evaluated using parenting scales, and the depression-anxiety-stress scales (DASS). The mothers were also asked to fill a strengths and difficulties questionnaire (SDQ) for their children. Furthermore, parenting styles in the case group were compared to mothers of children without asthma as the control group. The data were then analyzed by SPSS 11.5, using Chi-square, ANOVA, and independent-samples t-test. RESULTS: The results of this study showed that 21 mothers (74.6%) were normal, but 12 mothers (26.7%) had a mild -, 9 (20%) a moderate - and 3 (6.7%) a severe degree of abnormality according to DASS. Independent-samples t-test showed a significant difference between the case and control groups regarding depression in mothers and laxness (p<0.001), over reactivity (p<0.013) and verbosity (p<0.031) in children with asthma. CONCLUSION: The results of this study demonstrated that anxiety and depression are partially frequent in mothers of children with asthma, and parenting styles are less affective in these families.

The relationship between serology of hepatitis E virus with liver and kidney function in kidney transplant patients.

Although hepatitis E virus (HEV) is well known to cause acute hepatitis, there are reports showing that HEV may also be responsible for progression of acute to chronic hepatitis and liver cirrhosis in patients receiving organ transplantation. In this study, we aimed to evaluate the prevalence of HEV in patients with kidney transplantation. In this study, 110 patients with kidney transplantation were recruited, and anti-HEV IgG, creatinine, alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and estimated glomerular filtration rate (eGFR) in the first, third and sixth months after renal transplantation were measured. The mean serum anti-HEV IgG titers in the study participants was 1.36 (range 0.23 to 6.3). Twenty-three patients were found to be seropositive for HEV Ab defined as anti-HEV IgG titer > 1.1. The difference in liver and renal function tests (creatinine, eGFR, AST, ALT and ALP) at different intervals was not significant between patients with HEV Ab titers higher and lower than 1.1 (p > 0.05). However, an inverse correlation was observed between HEV Ab and eGFR values in the first (p = 0.047, r = -0.21), third (p = 0.04, r = -0.20) and sixth (p = 0.04, r = -0.22) months after renal transplantation in patients with HEV Ab < 1.1 but not in the subgroup with HEV Ab > 1.1. Also, a significant correlation between age and HEV Ab levels was found in the entire study population (p = 0.001, r = 0.33). Our findings showed a high prevalence of seropositivity for anti-HEV IgG in patients receiving renal transplants. However, liver and renal functions were not found to be significantly different seropositive and seronegative patients by up to 6 months post-transplantation.
