History of Small for Gestational Age at Birth With Verbal and Non-verbal Intelligence: A Case-Control Study Among Preschool Children.

Objective: Advances in technology and treatments have improved the survival rate of small for gestational age (SGA) infants that need more concern for their neurodevelopmental outcomes. In the present study, we hypothesized that a history of SGA may affect verbal and non-verbal intelligence indices among pre-school children. Materials and methods: A case-control study was conducted at the Tehran University of Medical Sciences (Tehran-Iran, 2020). Totally 232 children entered the study. An expert pediatrician examined all included subjects. Based on birth weight (extracted from medical records), participants were divided into the case (born SGA) and control (born Appropriate for gestational age (AGA)) groups. Wechsler Intelligence Scale (WISC) and Conners tests were implemented to assess intelligence quotient (IQ), verbal, attention, development, and executive functions. Finally, total scores were compared between groups. Results: Totally, 232 preschool children were included in the study. Of all, 114 (49.1%) and 118 (50.9%) subjects had the history of born SGA and AGA, respectively. The results related to WISC scores showed that the mean WISC-verbal score among children born SGA was significantly higher than children born AGA; (114.288±18.130 vs. 108.898±20.145; P=0.024). This significant difference was associated with Vocabulary (13.531±2.843 vs. 12.745±3.242; p=0.046) and Similarities (14.054±3.630 vs. 13.279±4.898; p=0.048) domains between the groups. The results related to different domains of the Conners test also showed that the mean scores of Inattention (B) and attention deficit hyperactive disorder score (D) in the case group were higher than these scores in the control group; however, these differences were not significant (4.929±3.511 vs. 4.906±4.300; p=0.495 &10.371±5.867 vs. 10.093±7.588; p=0.211). Conclusion: Our results indicated that the development of non-verbal intelligence in children born with SGA had been delayed. This finding shows that these children may need more consideration during the preschool period and after that.

Epidemiology of nosocomial Staphylococcus epidermidis and Acinetobacter baumannii infections in a neonatal intensive care unit.

Background and Objectives: This study aimed to investigate epidemiology of Staphylococcus epidermidis (S. epidermidis) and Acinetobacter baumannii (A. baumannii) infections in neonatal intensive care unit (NICU) in a period of 8 years. Materials and Methods: This retrospective cohort study was conducted on 46 cases of nosocomial infection by S. epidermidis, and 44 neonates with A. baumannii in NICU of Valiasr hospital, Iran. Results: The trend of A. baumannii and S. epidermidis infection were as follows: 1 and 7 in 2014, 11 and 7 in 2015, 20 and 11 in 2016, 1 and 4 in 2017, 4 and 6 in 2018, 4 and 4 in 2019, 0 and 1 in 2020, and 3 and 6 in 2021-March 2022 respectively. Mortality proportion (%) in neonates with S. epidermidis and A. baumannii infection was at 8.3 and 32.1, respectively. There was a strong positive correlation between number of infected neonates in month and average of prescribed antibiotics before incidence of infection in every baby in that month. Fluconazole prescription before incidence of infection were associated with the A. baumannii infection in month too. Amikacin prescription had adjusted correlation on increasing of A. baumannii and S. epidermidis infection in month. Conclusion: It seems reducing of hospitalization duration and medication prescriptions management plays an important role in reducing of nosocomial infections.

Iodine Status of Preterm Infants Born in an Area of Iodine Sufficiency: Are They at Risk of Iodine Deficiency?

OBJECTIVE: To the assess the iodine status of preterm infants born in an area of iodine sufficiency using the urinary iodine concentration (UIC) and thyroid-stimulating hormone (TSH) levels and compare these values across different feeding practices during the first 7 days of life. METHODS: In this cross-sectional study, 88 preterm infants born at 30 to 34 weeks of gestation and admitted to the neonatal intensive care unit of a referral hospital in Tehran (Iran) were included. The infant UIC and TSH levels and breast milk iodine concentration in mothers who were exclusively breastfeeding were measured. RESULTS: Median (interquartile range [IQR]) UIC and TSH levels in the study population were 81 (39-189) µg/L and 1.60 (0.80-2.85) mIU/L, respectively. When preterm infants were stratified by the type of feeding, the median (IQR) UICs were 64 (42-126) µg/L in parenteral nutrition, 125 (41-195) µg/L in exclusively breastfeeding, 57 (28-123) µg/L in formula feeding, and 45 (35-132) µg/L in mixed feeding, with no statistically significant difference between the groups (P = .31). The median (IQR) breast milk iodine concentration was 271 (177-521) µg/L in preterm infants exclusively fed their mothers' own milk. There was no significant difference in the proportion of the TSH levels of >5 mIU/L between preterm infants who received enteral and parenteral nutrition (P = .27). CONCLUSION: Preterm infants are at risk of iodine deficiency even in an area where the general population has adequate iodine. Only the preterm infants who received exclusively their mothers' own milk had marginally adequate iodine status. Further studies are warranted to determine the necessity of iodine supplementation for this vulnerable group.

Tehran environmental and neurodevelopmental disorders (TEND) cohort study: Phase I, feasibility assessment.

PURPOSE: To advance knowledge about childhood neurodevelopmental disorders and study their environmental determinants, we conducted a study in Tehran, Iran to assess the feasibility of prospective birth cohort study. METHODS: We evaluated participation of pregnant women, feasibility of sampling biological material, and health care services availability in Tehran in four steps: (1) first trimester of pregnancy; (2) third trimester of pregnancy; (3) at delivery; and (4) two to three months after delivery. We collected related data through questionnaires, also various biological samples were obtained from mothers (blood, urine, milk and nails-hands and feet) and newborns (umbilical cord blood, meconium, and urine samples) from February 2016 to October 2017. RESULTS: overall 838 eligible pregnant women were approached. The participation rate was 206(25%) in our study and about 185(90%) of subjects were recruited in hospitals. Out of 206 participants in the first trimester, blood, urine, hand nail, and foot nail samples were collected from 206(100%),193(93%), 205(99%), and 205(99%), respectively. These values dropped to 65(54%), 83(69%), 84(70%), and 84(70%) for the remaining participants 120(58%) in the third trimester, respectively. Also, we gathered milk samples from 125(60%) of mothers at two to three months after delivery. CONCLUSION: Our findings suggest that hospitals were better places for recruitment of subjects in a birth cohort in Tehran. We further concluded that birth cohort study recruitment can be improved by choosing appropriate gestational ages. Obtaining the newborn's urine, meconium, and umbilical cord blood were challenging procedures and require good collaboration between hospital staff and researchers.

Duration of Breastfeeding and Maternal-Related Factors in Iran, Systematic Review and Meta-Analysis.

BACKGROUND: Although the benefits of breastfeeding are commonly approved, there remains a significant discrepancy between maternal practices and World Health Organization (WHO) guidelines in some countries. OBJECTIVES: We had two aims in this study; average duration of breastfeeding, and its maternal determinants. DATA SOURCES: A web-based citation index was used for citing documents. STUDY ELIGIBILITY CRITERIA AND PARTICIPANTS: We included observational studies evaluating breastfeeding duration among children who were at least two years old and not older than five were included in Iran. SYNTHESIS METHODS: The pooled mean and mean differences were considered. Heterogeneity was evaluated with the I2 statistic. RESULTS: The pooled mean of breastfeeding duration was calculated at 17.31 months. Children with younger mothers and lower birth orders had shorter durations of breastfeeding. Women with a high school and higher education level had early cessation of breastfeeding in comparison with less educated women. LIMITATIONS: The main limitation of the current study was lack of librarian assistance. CONCLUSIONS: The pooled mean of breastfeeding duration in Iranian children aged 2-5 was less than WHO recommendations. Accurate identification of the effect a mother's level of education has on duration of lactation requires standardized categorization. IMPLICATIONS OF KEY FINDINGS: Raising awareness among women can be an effective strategy in increasing the duration of lactation.

Iranian neonatal diabetes mellitus due to mutation in PDX1 gene: a case report.

BACKGROUND: Neonatal diabetes mellitus with hyperglycemia during the first 6 months of life is a rare disorder that can occur in all races and societies. CASE PRESENTATION: In this study, we introduced an Iranian (Persian) 65-day-old patient with neonatal diabetes mellitus with novel homozygous mutation in the pancreatic and duodenal homeobox 1, PDX1, gene, which is also known as IPF1 gene, located in exon 2. This case was a newborn boy born in Vali-Asr Hospital, Tehran; he was diagnosed as having hyperglycemia on 28th day. Genetic analysis detected a homozygous mutation on PDX1 gene on chromosome 13. It is a novel homozygous mutation in the PDX1 gene (NM_000209.3), p.Phe167Val. This mutation was confirmed by Sanger sequencing. There was no evidence of agenesis of the pancreas. CONCLUSIONS: We reported a case of neonatal diabetes mellitus due to novel homozygous mutation in the PDX1 gene without exocrine pancreas manifestations.

Exclusive Breastfeeding Duration and its Effect on the Health of the Children in Iran, a Meta Analysis.

PROBLEM: Given the importance of exclusive breastfeeding (EB) duration on growth and to maintain health in children, we decided to systematically review the existing research on EB duration and its effect on the health of 2- to 5-year-old children in Iran. ELIGIBILITY CRITERIA: A systematic literature search was conducted in the Database of Abstracts of Reviews of Effects (DARE), Google Scholar, PubMed, Psyc INFO, Thomson Reuters, Cochrane, and Medical Library (MedLib) to detect appropriate studies (1994 to 2016). Outcomes of mean, mean difference, and proportions were pooled. SAMPLE: In this meta-analysis, 38 studies met the eligibility criteria. RESULTS: The pooled mean of EB was calculated as 4.1 months (CI 95%: 3.2, 4.99). The meta prevalence of EB up to 4 months and 5 to 6 months was estimated 65.0% (CI 95%: 54.0, 77.0) and 54% (CI 95%: 46.0, 62.0) respectively. Based on studies conducted over the years from 1994 to 2016, an increasing trend of EB was found in infants up to 4 months (p ≤ 0.0001). Among children with anemia and respiratory diseases EB until 5 to 6 months was more common than in healthy children (CI 95%; 1.1, 2.11, and 1.01, 1.47 respectively). CONCLUSION: The duration of EB (4.1 months) was equal to the lower limit recommended by the World Health Organization (WHO). Overall, the duration of EB until 5 to 6 months is sufficient if the child's iron intake is well-monitored. IMPLICATION: Monitoring of the implementation of recent guidelines or even modification of the duration period of the iron administration is potentially necessary.

Is there any difference between the iodine statuses of breast-fed and formula-fed infants and their mothers in an area with iodine sufficiency?

Despite substantial progress in the global elimination of iodine deficiency, lactating mothers and their infants remain susceptible to insufficient iodine intake. This cross-sectional study was conducted to compare iodine statuses of breast-fed and formula-fed infants and their mothers at four randomly selected health care centres in Tehran. Healthy infants <3 months old and their mothers were randomly selected for inclusion in this study. Iodine was measured in urine and breast milk samples from each infant and mother as well as commercially available infant formula. The study included 124 postpartum mothers (29·2 (sd 4·9) years old) and their infants (2·0 (sd 0·23) months old). The iodine concentrations were 50-184 µg/l for infant formula, compared with a median breast milk iodine concentration (BMIC) of 100 µg/l in the exclusive breast-feeding group and 122 µg/l in the partial formula feeding group. The median values for urinary iodine concentration in the exclusive breast-feeding group were 183 µg/l (interquartile range (IQR) 76-285) for infants and 78 µg/l (IQR 42-145) for mothers, compared with 140 µg/l (IQR 68-290) for infants and 87 µg/l (IQR 44-159) for mothers in the formula feeding group. These differences were not statistically significant. After adjustment for BMIC, ANCOVA revealed that feeding type (exclusive breast-feeding v. partial formula feeding) did not significantly affect the infants' or mother's urinary iodine levels. Thus, in an area with iodine sufficiency, there was no difference in the iodine statuses of infants and mothers according to their feeding type.

Breast Milk Iodine Concentration Rather than Maternal Urinary Iodine Is a Reliable Indicator for Monitoring Iodine Status of Breastfed Neonates.

There is no scientific consensus on whether breast milk iodine concentration (BMIC) accurately reflects iodine status in lactating mothers and breastfed infants. This study aimed to compare BMIC and maternal urinary iodine concentration (UIC) as indicators of iodine status in breastfed neonates. In this cross-sectional study, 147 lactating mothers and their neonates (3-5 days postpartum) were randomly selected from health care centers. Breast milk and urine samples were collected from each mother and neonate, and a heel-prick blood sample was taken from all neonates as part of a congenital hypothyroidism screening program. According to the World Health Organization criteria, median urinary iodine concentration (UIC) ≥ 100 µg/L in lactating mothers and neonates indicates iodine sufficiency. In areas of iodine sufficiency, median BMIC ≥ 100 µg/L is considered an adequate level. Overall, 129 (89.0%) and 16 (11.0%) mothers had BMICs ≥ 100 and ˂ 100 µg/L, respectively. Median (interquartile range [IQR]) maternal UIC was 70 µg/L (42-144 µg/L) and 37 µg/L (25-100 µg/L) in mothers with breast milk iodine levels ≥ 100 and ˂ 100 µg/L, respectively (P = 0.047); values for UIC of neonates born to mothers with BMICs ≥ 100 and ˂ 100 µg/L were 230 µg/L (114-310 µg/L) and 76 µg/L (41-140 µg/L), respectively (P < 0.001). In the linear regression model, neonate UIC was positively associated with BMIC in both unadjusted (ß = 0.558, P < 0.001) and adjusted analysis (ß = 0.541, P < 0.001). A similar result was found in logistic regression analysis, indicating that neonates born to mothers with BMIC ≥ 100 µg/L were more likely to have UIC ≥ 100 µg/L compared to those whose mothers had BMIC < 100 µg/L in both unadjusted (OR = 7.93, P < 0.001) and adjusted analysis (OR = 7.29, P = 0.001). The present findings indicate that BMIC is a more sensitive indicator than maternal UIC for assessment of iodine status in breastfed neonates. To address low levels of maternal UIC, further studies on the prescription of supplements containing 150 µg/day iodine during lactation period are warranted.

Breast-Milk Iodine Concentrations and Iodine Levels of Infants According to the Iodine Status of the Country of Residence: A Systematic Review and Meta-Analysis.

BACKGROUND: Iodine, an essential micronutrient, plays a critical role in normal growth and development, especially during the first two years of life. This systematic review and meta-analysis is among the first to evaluate breast-milk iodine concentrations and infant iodine status in countries characterized by iodine sufficiency or deficiency. METHODS: PubMed, Web of Science, Cochrane Library, Google Scholar, and other relevant databases, as well as reference lists of previous reviews, were searched for relevant studies published between 1986 and 2016. Mean or median breast-milk and infant urinary iodine concentrations, along with other relevant data, were extracted from eligible studies. Each study was assessed for quality and risk of bias. RESULTS: Of the 496 identified studies, 57 met the criteria for inclusion in the meta-analysis. The mean (confidence interval [CI]) iodine concentrations in maternal colostrum were 152.0 µg/L [CI 106.2-198.7 µg/L] and 57.8 µg/L [CI 41.4-74.1 µg/L] in iodine-sufficient and -deficient countries, respectively, indicating a significant difference between the two iodine statuses. By contrast, the corresponding values in mature milk did not differ significantly between mothers in iodine-sufficient and -deficient countries (71.5 µg/L [CI 51.0-92.0 µg/L] and 28.0 µg/L [CI -13.8 to 69.9 µg/L], respectively]. The weighted urinary iodine levels [CIs] of breast-fed infants in iodine-sufficient countries were significantly higher than those in iodine-deficient countries (164.5 µg/L [CI 116.4-212.7 µg/L] vs. 70.4 µg/L [CI 46.2-94.6 µg/L]). Similarly, a significant difference was observed in the pooled estimates of urinary iodine levels [CIs] among formula-fed infants in iodine-sufficient versus iodine-deficient countries (310.3 µg/L [CI 287.4-342.1 µg/L] vs. 38.3 µg/L [CI 23.4-53.2 µg/L]). CONCLUSION: The meta-analysis reveals that in iodine-sufficient countries, the mean iodine concentrations in colostrum and mature breast milk corresponded to iodine sufficiency among infants. The results are thus compatible with the international recommendation that lactating women and infants younger than two years of age who reside in iodine-sufficient countries do not require iodine supplementation.

Association of SP-B gene 9306 A/G polymorphism (rs7316) and risk of RDS.

BACKGROUND: Respiratory distress syndrome (RDS) is a severe pulmonary disease predominantly affects preterm newborns. Polymorphisms of surfactant-protein genes have been mostly evaluated as the candidate contributors in genetics of RDS. However the results are divers in different studies. We aimed at investigating the association of surfactant protein B (SPB) gene 9306 A/G polymorphism (rs7316) with RDS development. METHOD: Three hundred and eighty newborns with gestational age of less than 34 weeks were included in a multicenter case-control study. Respiratory distress (RD) was scored according to Downes' scoring system. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for genotyping. RESULT: One hundred and eighty-four neonates showed RDS and 196 did not. Gestational age (GA) was significantly lower in the RDS group compared with the controls. AA genotype and A allele were found more frequently in the RDS group than the controls (96.2% versus 63.8% and 98.1% versus 80.6%, respectively) (p =.0001). CONCLUSIONS: This is the first report of association of SFTPB rs7316 polymorphism with RDS development in Iranian newborns. The current study suggests that GA <28-weeks is the most important factor in predisposition to RDS. Genetic background in terms of SP-B gene might be involved in predisposition to RDS in premature neonates.

Comparison of Fecal Calprotectin in Exclusively Breastfed and Formula or Mixed Fed Infants in the First Six Months of Life.

We conducted this study to compare fecal calprotectin between exclusively breastfed and formula or mixed fed infants aged one month and six months. Sixty term infants were enrolled from the labor ward of Valiasr Hospital between Oct 2011 and July 2015 and their fecal calprotectin was checked by the ELISA method and Hycult biotech kits. The enrolled infants had a birth weight of 2500-4000 g and no perinatal insults or hospitalization. Stool sampling was done at 1±1 week and at 6n±1 months. The six-month infants had no recent disease, antibiotic use or vaccination. The mean fecal calprotectin was higher in exclusively breastfed infants at first and sixth months than formula and mixed fed infants (368.85±204.49 and 283.21±381.41 µg/g versus 152.59±139.13 and 113.62±92.75 µg/g respectively). (P=0.0001 and 0.018) Fecal calprotectin was higher in infants with GERD than healthy babies in the first and sixth months (P=0.0001 and 0.004). Based on the role of calprotectin in inflammation, its higher levels in exclusively breastfed infants is contrary to breast milk benefits and may be a sign of enhanced mucosal immune maturity in them.

Hemophagocytic Lymphohistiocytosis in a Neonate: Case Report.

 Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of pathologic immune activation, occurring as either a familial disorder or a sporadic condition, in association with a variety of triggers. This article will introduce a neonate with HLH in Iran. We report a case of HLH presenting with respiratory distress and fever, hepatosplenomegaly, jaundice and pancytopenia on the second day of life. Typical clinical and laboratory findings were detected in the neonate. HLH was diagnosed according to HLH-2004 guidelines. In spite of initiating the treatment, the disease did not cure. Post-mortem, extensive hemophagocytosis was found in multiple organs. No specific genetic defect was identified. Since HLH is a potentially lethal childhood illness, early diagnosis of this disorder and commences the therapy is important for pediatricians.

Association of SP-C gene codon 186 polymorphism (rs1124) and risk of RDS.

BACKGROUND: Respiratory distress syndrome (RDS) is a severe pulmonary disease that mainly affects preterm neonates. Surfactant-protein genes' polymorphisms have been mostly evaluated as the candidate contributors in genetics of RDS. However, the results are diverse in different populations. We aimed at investigating the association of rs1124 with RDS development. METHOD: Three hundred and thirty five preterm neonates were enrolled in a multicenter case-control study. Respiratory distress (RD) was scored according to Downes' scoring system. Genotyping was performed by PCR-RFLP method. RESULT: One hundred and sixty six neonates showed RDS and 169 did not. Gestational age (GA) was significantly lower in RDS group compared to the controls. In female preterm newborns, AA genotype was found more frequently in RDS group. In RDS group, AA genotype was also associated with milder RD irrespective of gender. In neonates who were born 28-34 weeks, RD appeared to be more severe in the RDS group and males. CONCLUSIONS: This is the first report of association of SFTPC rs1124 polymorphism with RDS development in Iranian newborns. The current study suggests that GA <28-weeks is the most important factor in predisposition to RDS. AA genotype is also, a predisposing factor for the development of RDS in female preterm infants.

Effects of Community-Based Newborn Care Intervention on Neonate Health Status in a District of Tehran (Iran).

OBJECTIVE: To identify the effects of community-based interventions on the Neonatal Health Index in one district of Tehran-Iran. MATERIALS AND METHODS: A community and healthcare center-based study was carried out from January 2011 through September 2014. The population of the study included newborns from mothers residing in the 4(th) district of Tehran, Iran. Demographic data of mothers and infants were recorded in questionnaires before and after intervention. Interventions were implemented in hospitals, participants' homes, and health centers. The primary outcomes were comparison of mean birth weight, weight gain during the first 3-7 days, first week visit rate, hospitalization rate between the before and after intervention groups. RESULTS: The populations in the before and after intervention groups were 274 and 250, respectively. A significant difference was seen between the gestational ages (P value = 0.007) of the two groups. Mean birth height in the first group was 50.35 ± 3.48 and in the second group was 55 ± 5.32 cm (P value = 0.04). Neonatal complications in the second group were 6.9% lower than in the first group (P value = 0.048). In the first group 41 neonates (15%) were hospitalized in the NICU while in the second group 12 cases (4.8%) were hospitalized (P value = 0.018). Seven cases (2.6%) in the first group and one case (0.4%) in the second group were resuscitated (P value = 0.0001). CONCLUSION: The results of implementing community-based newborn care strategies witnessed at the first week postnatal visit included improvements inneonatal gestational growth, management of neonates with potentially serious illnesses, diagnosis of warning signs and neonatal care practices.

Intraventricular Hemorrhage in a Term Neonate: Manifestation of Protein S Deficiency- A Case Report.

Protein S (PS) is an antithrombotic plasma protein that plays essential roles in limiting thrombus formation in the anticoagulant system. Protein S deficiency is related with recurrent thrombosis. Here, the authors report a case of a term neonate with severe PS deficiency in year 2015, Imam Hospital, Tehran, Iran, that had seizures and intraventricular hemorrhage (IVH) since the age of 3 days. Nine-month follow-up did not show any developmental problems and MRI showed no hemorrhage.

Comparison of the Combined versus Conventional Apgar Scores in Predicting Adverse Neonatal Outcomes.

OBJECTIVES: Assessing the value of the Combined-Apgar score in predicting neonatal mortality and morbidity compared to the Conventional-Apgar. METHODS: This prospective cohort study evaluated 942 neonates (166 very preterm, 233 near term, and 543 term) admitted to a tertiary referral hospital. At 1- and 5-minutes after delivery, the Conventional and Combined Apgar scores were recorded. The neonates were followed, and the following information was recorded: the occurrence of severe hyperbilirubinemia requiring medical intervention, the requirement for mechanical ventilation, the occurrence of intraventricular hemorrhage (IVH), and neonatal mortality. RESULTS: Before adjusting for the potential confounders, a low Conventional (<7) or Combined (<10) Apgar score at 5-minutes was associated with adverse neonatal outcomes. However, after adjustment for the gestational age, birth weight and the requirement for neonatal resuscitation in the delivery room, a depressed 5-minute Conventional-Apgar score lost its significant associations with all the measured adverse outcomes; after the adjustments, a low 5-minute Combined-Apgar score remained significantly associated with the requirement for mechanical ventilation (OR,18.61; 95%CI,6.75-51.29), IVH (OR,4.8; 95%CI,1.91-12.01), and neonatal mortality (OR,20.22; 95%CI,4.22-96.88). Additionally, using Receiver Operating Characteristics (ROC) curves, the area under the curve was higher for the Combined-Apgar than the Conventional-Apgar for the prediction of neonatal mortality and the measured morbidities among all the admitted neonates and their gestational age subgroups. CONCLUSIONS: The newly proposed Combined-Apgar score can be a good predictor of neonatal mortality and morbidity in the admitted neonates, regardless of their gestational age and resuscitation status. It is also superior to the Conventional-Apgar in predicting adverse neonatal outcomes in very preterm, near term and term neonates.

Effects of baby massage on neonatal jaundice in healthy Iranian infants: A pilot study.

OBJECTIVE: To evaluate the effects of baby massage on transcutaneous bilirubin levels and stool frequency of healthy term newborns. METHODS: This Pilot study was conducted on 50 healthy newborns in Valiasr Hospital of IKHC. The infants were randomly allocated to two treatment (massage) and control group. The massage group received massage therapy (according to Touch Therapy) for four days from the first day postnatal while the control group received routine care. Main variable studied were transcutaneous bilirubin level (TCB) and stool frequency which were compared in two groups. RESULTS: There were 50 newborns in the study 25 in each group (50%). There was a significant difference in the TCB levels between two groups (p=0.000) with those in the massage group having lower bilirubin levels. As for the stool frequency there was a significant difference in two groups on the first day showing more defecation in the control group (p=0.042) which on the consequent days was not significant and the frequencies were almost similar. CONCLUSION: Massage group had a lower transcutaneous billirubin levels compared to the control group, thus, these pilot results indicate that massaging the newborns can be accompanied by a lower bilirubin level in the healthy term newborn.

Umbilical blood gas analysis in preeclamptic versus healthy pregnancies with preterm birth.

OBJECTIVE: Comparing the value of umbilical cord arterial blood gas (UC-ABG) analysis in the prediction of neonatal mortality and morbidity in the preeclamptic versus healthy pregnancies with preterm birth. METHODS: Eight hundred sixteen preterm (born at <37 gestational weeks) neonates with no other morbidities who were born by cesarean section were evaluated. Immediately after delivery, UC-ABG analysis was performed and the neonates were followed. RESULTS: Preeclamptic women had lower umbilical cord blood (UCB) pH (7.2 4 ± 0.1 versus 7.2 7 ± 0.08, p = 0.008) and higher UCB base deficit (BD) (3.5 ± 3.7 versus 2.2 ± 3.4, p = 0.005) compared with controls. In the preeclamptic group, UCB metabolic acidosis (pH < 7.15 and B.D > 8) was not independently associated with neonatal morbidity or mortality, while in the control group UCB metabolic acidosis was independently associated with low 10-min Apgar (OR, 4.9; 95%CI 1.37-18.03), respiratory distress syndrome (OR, 2.37; 95%CI 1.05-6.17), intraventricular hemorrhage (OR, 3.01; 95%CI 1.13-7.99), and neonatal mortality (OR, 17.33; 95%CI 4.51-66.53). CONCLUSIONS: The preterm neonates born to preeclamptic mothers have lower UCB pH and higher BD. In these neonates, UCB acidosis is not independently associated with any adverse neonatal outcomes. In contrast, in the preterm neonates born to healthy mothers, UCB metabolic acidosis is independently associated with neonatal mortality and morbidity.

Frequency of "Nursing Strike" among 6-Month-Old Infants, at East Tehran Health Center and Contributing Factors.

OBJECTIVE: An abrupt refusal by the infant to breastfeed is often called "nursing strike". In fact a common reason for cessation of nursing is infant's refusal to breast feed. This problem can often be overcome. This paper has aimed to identify the causes of "breast feeding refusal" or "nursing strike" in 6 month old infants visiting the East Tehran health center for their scheduled vaccination of 6 months old. MATERIALS AND METHODS: Totally 175 six month old infants were enrolled in this study. A questionnaire was filled by mother for each child and later the infants with "nursing strike" were compared with all others. RESULTS: In this study prevalence of breast feeding refusal in infants was 24%.There was significant relation between the "breastfeeding refusal" and maternal academic education or working status. In this study mothers reported various reasons associated with "refusal breast feeding. According to the mothers playful infant and nasal obstructions were the probable causes for refusal. CONCLUSION: There is a diverse variety of factors influencing nursing strike. Most of these factors can be prevented by identifying the background reasons and proper training.
