Background: This study aimed to address the increasing prevalence of cesarean section and the importance of evaluating newborn health through arterial blood gas analysis. Its primary objective was to compare the umbilical cord blood gas levels in newborns delivered through different delivery methods., Method: This retrospective descriptive cross-sectional study included singleton pregnancies with a gestational age between 37 and 42 weeks and infants weighing between 2500 and 4000 g. Newborns with an Apgar score of 7 or higher at 1 and 5 min were included. Umbilical cord blood samples were collected from each newborn for blood gas analysis within 60 min after birth., Result: The study included 340 neonates, with 170 born via caesarean section and 170 born through vaginal delivery. No significant differences were observed in Apgar scores between two groups. ABG analysis showed that vaginally born neonates had lower pH (7.24 ± 0.08 vs. 7.27 ± 0.07, P < 0.001), PCO2 (P = 0.015), and HCO3 (P < 0.001). Cesarean section neonates had higher oxygen saturation (P = 0.007) and pressure of oxygen (P < 0.001), and less negative base excess (P < 0.001). In the subgroup analysis, neonates whose mothers received epidural anesthesia had lower pH (7.23 ± 0.07 vs. 7.25 ± 0.08, P = 0.021) and more negative base excess (P = 0.026). Other parameters of ABG did not differ significantly between the groups (P > 0.05)., Conclusion: It has been proven that the mode of delivery, whether it is vaginal or cesarean, as well as the administration of epidural anesthesia during vaginal delivery, have a significant impact on newborns at birth. Newborns delivered vaginally exhibit metabolic acidosis compared to those delivered via cesarean section. Although these differences are statistically significant, they do not have a notable clinical significance, as the average values of the evaluated parameters in both groups fall within the normal range., (© 2024.

Background: Persistent Pulmonary Hypertension of the newborn (PPHN) is characterized by sustained elevated Pulmonary Artery Pressure (PAP). Drug resistance and the adverse effects of current therapeutic agents warrant investigation of other targeted therapies. Bosentan has shown benefits in affected neonates. However, trials reported the association with unwanted effects. Thus, in this study, we assess another agent in the same family, Macitentan. However, its efficacy in the treatment of PPHN is not yet reported. Hence, this study evaluated the effect of Macitentan compared to Bosentan in terms of efficacy and safety in the treatment of PPHN., Methods: This randomized, double-blinded non-inferiority clinical trial was conducted in Shahid Akbar Abadi hospital, Tehran, Iran. Sixty clinically stable neonates with signs suggestive of PPHN were randomly allocated into two groups (n = 30 in each group) and they received either Bosentan 1 mg/kg/dose BD (twice daily) or Macitentan 1 mg/kg/dose BD simultaneously with sildenafil. The echocardiographic and laboratory indices of efficacy and safety were compared between groups. SPAP (systolic pulmonary artery pressure) was used to assess the non-inferiority of the Macitentan compared to the Bosentan in their respective doses used in the study., Results: Participants' mean (SD) age was 3.53 (1.21) days, and 55% were female. No mortality case occurred. SPAP was reduced in both Bosentan and Macitenan groups with the mean difference in SPAP of 9 (95% CI: 7.34-10.65) in Bosentan and SPAP mean difference of 14 (95% CI: 12.12-15.86) in Macitentan group. Categorical comparison of primary outcome improvement showed that Macitentan was superior to Bosentan with a 10% non-inferiority margin. Similar results were obtained in other echocardiographic indices. Also, no significant alterations were observed in laboratory safety parameters., Conclusion: Macitentan 1 mg/kg/dose BD (twice daily) is non-inferior to Bosentan 1 mg/kg/dose BD in improving echo outcomes of PPHN and it was even more effective in improving some of these. Also, it is non-inferior to Bosentan in terms of safety.

Background: Screening for critical congenital heart defects should be performed as early as possible and is essential for saving the lives of children and reducing the incidence of undetected adult congenital heart diseases. Heart malformations remain unrecognized at birth in more than 50% of neonates at maternity hospitals. Accurate screening for congenital heart malformations is possible using a certified and internationally patented digital intelligent phonocardiography machine. This study aimed to assess the actual incidence of heart defects in neonates. A pre-evaluation of the incidence of unrecognized severe and critical congenital heart defects at birth in our well-baby nursery was also performed., Methods: We conducted the Neonates Cardiac Monitoring Research Project (ethics approval number: IR-IUMS-FMD. REC.1398.098) at the Shahid Akbarabadi Maternity Hospital. This study was a retrospective analysis of congenital heart malformations observed after screening 840 neonates. Using a double-blind format, 840 neonates from the well-baby nursery were randomly chosen to undergo routine clinical examinations at birth and digital intelligent phonocardiogram examinations. A pediatric cardiologist performed echocardiography for each neonate classified as having abnormal heart sounds using an intelligent machine or during routine medical examinations. If the pediatric cardiologist requested a follow-up examination, then the neonate was considered to have a congenital heart malformation, and the cumulative incidence was calculated accordingly., Results: The incidence of heart malformations in our well-baby nursery was 5%. Furthermore, 45% of heart malformations were unrecognized in neonates at birth, including one critical congenital heart defect. The intelligent machine interpreted innocent murmurs as healthy heart sound., Conclusion: We accurately and cost-effectively screened for congenital heart malformations in all neonates in our hospital using a digital intelligent phonocardiogram. Using an intelligent machine, we successfully identified neonates with CCHD and congenital heart defects that could not be detected using standard medical examinations. The Pouya Heart machine can record and analyze sounds with a spectral power level lower than the minimum level of the human hearing threshold. Furthermore, by redesigning the study, the identification of previously unrecognized heart malformations could increase to 58%., Competing Interests: AAS was employed by the CAPIS research and development company based in Belgium.

Background: Neonates in the neonatal intensive care unit are frequently subjected to painful procedures. Non-pharmacological pain control techniques are useful for reducing procedural pain. Touch as one of the aspects of developmental care used to reduce neonatal pain. The purpose of this study was to determine the effect of gentle human touch during endotracheal suctioning on procedural pain response in preterm neonates., Methods: This was a clinical trial study with a crossover design. The study was conducted in a level III NICU in a hospital, affiliated to Iran University of Medical Sciences. Thirty-four neonates were enrolled in this study based on inclusion criteria. The samples were randomly received a sequence of suctioning with/without or suctioning without/with gentle human touch. Preterm Infant Pain Profile (PIPP) was used to collect the data. SPSS version 22 for Windows (SPSS Inc., Chicago, IL, USA) was used for statistical analysis., Results: 85.3% of neonates experienced moderate and 8.8% severe pain during suctioning without intervention, and only 64.7% of them experienced moderate and 2.9% severe pain during suctioning with intervention. The results of the paired t -test show that there is a statistically significant difference between the mean scores of pain in nonintervention and intervention cases ( p  < .002), and the mean pain score substantially reduced in cases with intervention., Conclusions: Results from this study showed that the pain due to suctioning procedure is considerably reduced by applying Gentle Human Touch. And nurses can use this method as one of the non-pharmacological methods of pain management.

Breast cancer, an unceasingly occurring neoplasm, is one of the major determinants of mortality in women. Several ineffective attempts have been pursued using with conventional therapies against breast cancer. Resistance to existing therapies and their respective debilitating adverse effects have led research toward a new era of cancer treatment using viruses. Virotherapy constitutes a developing treatment modality with multiple mechanisms of therapeutic activity in which the viruses can be directly oncolyticand can express transgenes or induce host immune response against tumor cells. Several different DNA- and RNA-containing viruses have been considered for virotherapy of breast cancer including adenovirus, herpes virus, vaccinia, reovirus, Newcastle Disease virus, measles virus and vesicular stomatitis virus. This review aims to summarize the viro-therapeutical agents against breast malignancies. Key Scientific Concepts of Review: In this review paper, we proposed a new strategy to virus's combinatorial treatments using several kinds of transgenes and drugs. These recombinant viruses have provided evidence of treatment efficacy against human breast cancer., Competing Interests: Authors declare no conflict of interests., (© 2021 The Authors.

Severe forms of COVID-19 can evolve into pneumonia, featured by acute respiratory failure due to acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). In viral diseases, the replication of viruses is seemingly stimulated by an imbalance between pro-oxidant and antioxidant activity as well as by the deprivation of antioxidant mechanisms. In COVID-19 pneumonia, oxidative stress also appears to be highly detrimental to lung tissues. Although inhaling ozone (O3) gas has been shown to be toxic to the lungs, recent evidence suggests that its administration via appropriate routes and at small doses can paradoxically induce an adaptive reaction capable of decreasing the endogenous oxidative stress. Ozone therapy is recommended to counter the disruptive effects of severe COVID-19 on lung tissues, especially if administered in early stages of the disease, thereby preventing the progression to ARDS., (Copyright © 2020 Elsevier B.V.

Very Low Birth Weight (VLBW) infants have higher nutritional needs than term infants. Energy and protein are two important factors influencing their growth. Breastfeeding is not enough to meet VLBW infants' needs, for this reason, complementary protein is required by them. Hence, the present study aimed at investigation of renal function among VLBW infants receiving complementary proteins. The study was conducted on two groups of intervention and control (n= 18 in each group) (Case study: VLBW infants born in Akbarabadi hospital of Tehran in 2014 2015). The intervention group includes 3-year-old children who weighting less than 1200 grams at birth and have received protein supplementation at the course of NICU hospitalization, protein was added to maternal milk when the amount of milk reaches to 100 cc/kg/day, at this time parenteral nutrition was discontinued and the volume of feeding was increased 20cc/kg/day until reached to 150-180cc/kg/day. We also added the fortifier to breast milk at this time. The fortification and the protein supplementation were stopped when the weight of the baby reached to 1500 grams. The control group was fed similar to the intervention group but had received no complementary protein . The renal function was evaluated by measuring such criteria as BUN, Cr, ALB and U/A. After data collection, a statistical analysis was performed using SPSS software Ver. 22. Following to BUN evaluation, a significant correlation was seen between BUN and received protein (p-value=0.010). However, there was no significant correlation between Cr and received protein as well as mean values of the two groups (p-value=0.0766). Similarly, an insignificant correlation was found between the two groups following to investigation of ALB (p-value=0/257), while the mean values of the two groups were similar. The both groups were also equal in U/A. The complementary protein increased the BUN with no effect on Cr, ALB and U/A, providing no impact on renal function. Therefore, complementary protein intake made no conflict in renal function., Competing Interests: We confirm that we have read the Journal’s position on issues involved in ethical publication and affirm that this report is consistent with those guidelines.

Introduction: Choice of appropriate nutrition has a special place, which variations in dietary nutrient can potentially be involved in growth deficits in preterm neonates., Aim: to investigate the effect of protein supplementation in very low birth weight (VLBW= birth weight under 1500 grams) infants on neurological growth in the third year of birth., Material and Methods: We investigated neurological growth in two groups of control and intervention (each group, n= 18 subjects). The intervention group includes 3-year-old children who weighting less than 1200 grams at birth and have received protein supplementation at the course of NICU hospitalization, protein was added to maternal milk when the amount of milk reaches to 100 cc/kg/day, at this time parenteral nutrition was discontinued and the volume of feeding was increased 20cc/kg/day until reached to 150-180cc/kg/day. We also added the fortifier to breast milk at this time (FMS- Aptamil- DANON). The fortification and the protein supplementation were stopped when the weight of the baby reached to 1500 grams. The control group was fed similar to the intervention group, without protein supplemental intake. Neurodevelopmental outcomes were evaluated using ASQ, NEWSHA and BINS tools., Results: There was no significant difference between the mean head circumference in the two groups (p=0.209). There was no significant relationship between neurological growth rate evaluated by BINS tool in two groups (p=0.266). There was a significant correlation between the neurological development assessed by the ASQ tool in the areas of communication (p=0.014) and gross motor (p=0.001) in the two groups, however, no significant relationship was found in terms of fine motor (p=0.63), problem solving (p=0.07) and personal-social relationships in both groups (p=0.152). There was a significant correlation between neurological development evaluated using the NEWSHA tool in terms of auditory (p=0.031), verbal language (p=0.024), cognitive (p=0.007), social connection (p=0.034) and motor (p=0.002) in the two groups., Conclusion: Protein intake in preterm infants didn't reveal long term effects on the growth of head circumference. Moreover, it was capable of improving neurological growth in the areas of communication and gross motor (based on the ASQ) and auditory, verbal language, cognitive, social connection, and motor (based on the NEWSHA)., Competing Interests: There are no conflicts of interest., (© 2019 Mandana Kashaki, Fatemeh Masoudi Samghabadi, Arash Bordbar.)

Background: The goal of this study was to evaluate the relationship between maternal 25-OH Vitamin D serum levels and neonatal early-onset sepsis in newborns by the effective factors., Methods: A case-control study was done and 64 neonates hospitalized in Akbar Abadi Hospital (Tehran- Iran; 2016) and their mothers were enrolled. The case group consisted of 32 NICU term hospitalized neonates due to neonatal early-onset sepsis. Thirty-two term newborns that referred to hospital for rule out hyperbilirubinemia during the first 72 h of life were also considered as the control., Results: Sixty- four mothers with mean age 28.76 ± 6.60 years and mean gestational age 39.64 ± 1.62 weeks entered the study. There was a significant correlation between sepsis and older age of mothers and low Apgar score (P-value = 0.02, 0.01 respectively). The maternal vitamin D serum level was reversely correlated with neonatal sepsis occurrence (P-value = 0.03). There was a significant correlation between maternal vitamin D supplement intake during pregnancy and lower risk for neonatal sepsis (P-value = 0.003)., Conclusion: The level of maternal serum Vitamin D was inversely correlated with neonatal sepsis occurrence and intake of vitamin D supplement during pregnancy could decrease the risk of early neonatal sepsis.

Objective: We measured the level of pH gases in premature infants at birth, and examined the relationship between brain ultrasonography on the third and seventh day after birth. A case-control study conducted at the Neonatal Intensive Care Unit (NICU) of Shahid Akbar Abadi Hospital, Iran, during the years 2016-2017., Methods: All premature infants who were admitted to NICU were enrolled in the current study. At birth, a blood gas sample was taken from the umbilical cord of the infants. On the third and seventh day after birth, an ultrasound of the brain of each neonate was performed by a radiologist. The umbilical cord was evaluated for blood gases in 72 neonates (mostly boys)., Results: Sixty-six newborns had normal sonography, and 16.7% (12 cases) had anomalies. A total of 75% of the 8 infants with intravenous bleeding were girls, which were significantly different from those in the non-hemodynamic group (62.5% male) (P 0.049). However, the type of delivery, mean weight, height, head circumference, the circumference of the chest, and Apgar score did not differ between the two groups. Mean pH, HCO3- and PCO2 in umbilical cord blood gas samples were not significantly different between the two groups with or without intraventricular hemorrhage (IVH). Although it was not related to gender and type of delivery in newborns., Conclusion: Blood gases do not help in determining the occurrence of IVH in infants. Nevertheless, it is associated with immaturity and fetal age.
