Abstract
Considering the fact that early hypocalcemia is the most common type of
neonatal hypocalcemia which manifests during the first few days of Iife (72 hours)
and that hypocalcemia in low birth weight neonates is very common, this descriptive
study on hypocalcemia was conducted to determine the frequency of hypocalcemia
in low birth weight neonates in the city of Kashan in the first 9 months of
the year 1997. A total of 250 infants weighing less than 2.5 kg were included in
this study. Variables such as gestational age, APGAR score, birth weight, preeclampsia
of mother and age of pregnancy were recorded. All of the newborns
were checked and laboratory tests for serum calcium level were performed on
them. Any full-term infant with a serum calcium level less than 8 mg/dL or preterm
infants with serum calcium levels less than 7 mg/dL were identified as hypocalcemic
infants. The results of the study showed that 22.4% of the infants
were hypocalcemic, most of these being neonates below ls00g weight. The frequency
of hypocalcemia in infants whose mothers were afflicted by pre-eclampsia
was 30.8%. The frequency of hypocalcemia in infants with low APGAR score
was 28.8% and for those neonates with a normal APGAR score, 21.2% (p

Abstract
ABSTRACT
Background: Very low birth weight infants ( <1500 g) frequently require blood transfusions because of repeated blood sampling accompanied by anemia of prematurity.
Methods: In an attempt to identify the effect of human recombinant erythropoietin to decrease the requirement for blood transfusions, erythropoietin was administered to 24 pre term infants less than 1500 g prospectively from September 1999 till December2000. Data about the characteristics of the population, the severity of diseases, and treatment with erythropoietin, clinical diagnosis, initial and subsequent hemoglobin, volume of blood loss, and the number of blood transfusions were recorded. These results were compared with data from the recorded information of 49 infants who did not receive erythropoietin during those past 2 years. There were no differences between the 2 groups with regard to the gestational age, birth weight, clinical diagnosis, severity of the illness, primary causes of admission, and initial hematologic parameters such as hemoglobin, hematocrit and reticulocytes. Erythropoietin was administered in a dose of 200 ill/kg three times weekly for 6-8 weeks accompanied with iron supplement 6 mg/ kg/day. Transfusions were administered according to protocol.
Results: There was no significant difference between the number of blood transfusion among these 2 groups (p= 0.07). However, transfusions in the erythropoietin treated group were fewer in comparison to the other group (1.9 +1-1.6 to 3.2 +/-1.1). No difference was observed between final hemoglobin and hematocrit levels among the two groups (10.3 +1- 0.9 vs. 10.4 +1- 0.7 and 33.7 +1- 2.3 vs. 32.2 +1- 2.2).
Conclusion: Very low birth weight infants receive frequent blood transfusions but a reduction in transfusion requirements was not apparent after administration of erythropoietin and iron in preterm infants in this study. However, the lack of impact on transfusion requirements fails to support routine use of erythropoietin.

Abstract
ABSTRACT
Background: Correction of the uremic state by a functioning allograft often restores fertility in women of reproductive age. The rate of fertility significantly differs between industrial countries, developing and middle east countries. On the other hand the results of pregnancy in Kidney Transplantation (KTP) patients are significantly better than hemodialysis patients, and pregnancy most often has no side effects on the function of the transplanted kidney.
Objectives: The purpose of this study is to investigate the rate of fertility and results of pregnancy among KTP women, and the assessment of the function of transplanted kidneys during pregnancy among those who have received kidneys in Golestan Hospital from 1996 to 2003.
Methods: All the transplanted women in child bearing age who were interested in accepting pregnancy were involved in this study. After pregnancy, all the patients were visited twice a month until the 32nd week of pregnancy and their histories were taken and regular clinical examination and necessary paraclinical assessments were carried out. After the 32nd week, they were visited weekly and other necessary assessments were done in addition to previous measures. Taking immunosuppressive drugs was continued with a minor dose reduction and consumption of harmful drugs like some antihypertensives was prohibited.
Results: 16 out of 48 women who were at child bearing age and were interested in pregnancy got pregnant and totally 22 cases of pregnancy occurred. Four cases resulted in spontaneous or therapeutic abortion and 3 out of 18 remaining cases had intrauterine fetal death and the others had successful pregnancy. The most common complication was LBW and following that premature labor. Maternal complications were no more than the general population and the function of the transplanted kidney had no decline in most of the cases.
Conclusion: Based on what was mentioned, it is concluded that successful KTP can increase the chance of pregnancy and in order to improve the results of pregnancy, it is necessary to prepare ideal conditions especially for the transplanted kidney before pregnancy, while pregnancy does not produce any decline in the function of the transplanted kidney.

Abstract
Background: Low birth weight neonates are confronted with some problems after
birth, they should be followed up and evaluated at different ages of life.The aim of this study was to determine the impact of birth weight on the risk of sensorineural hearing impairment on children.
Method: This cross sectional and retrospective study determined the prevalence
of hearing problems in low birth weight and normal birth weight school age children.
The sample was consisted of 2400 children who referred to special educational organization for hearing screening before entrance to school in Mashhad - Iran between
June 2005 and June 2006. Hearing problems were checked in all groups. Case definition was based on the mean sensorineural hearing loss of more than 35 decibel (dB) hearing level (HL) and in the better-hearing ear averaged over the pure-tone hearing thresholds at 500, 1000, 2000 and 4000 Htz. The results were then compared the low birth weight and normal birth weight children.
Result: This study showed that prevalence of hearing problems was 1.4%. The
prevalence of hearing impairment in low birth weight (LBW) was 2.1% and 1.3% in
normal birth weight (NBW). There wasn't significant difference in hearing impairment
between two groups (p=0.255).
Conclussion: In this study there was no significant difference between low birth
weight and normal birth weight children in hearing impairment although other studies
indicated that the risks of hearing impairment increase with the LBW and low
gestational age neonates. More investigation is needed for detecting the subtle hearing
problems in children.

Abstract
Background: The aim of study was to compare the effect of Kangaroo mother care (KMC) and conventional methods of care (CMC) in low birth weight babies less than 2000 grams.
Method: One hundred babies with birth weight less than 2000 grams and without clinical problem were
randomized in two groups the intervention group (N=50) who received Kangaroo mother care and the control group (N=50) with conventional care. Two groups were compared in daily weight gaining, self confidence of mother, duration of hospitalization, clinical cyanosis and nosocomial infection. Collected data was analyzed by SPSS 11.5 software . Irct ID: IRCT201101091162N16.
Results: The KMC babies had better daily weight gaining average [18.31±7.57gm vs. 4.8±16.57gm (P<
0.001)] CMC: and also, self confidence of mother in KMC group was significantly higher than CMC group
(p<0.001). A significantly longer duration of hospitalization observed in CMC group [27.18±12.07 day vs.
16.24±10.04 day (P<0.001)]. There was no significant difference between the two groups for clinical cyanosis and nosocomial infection (both P>0.05).
Conclusions: In this study Kangaroo mother care had better effect on daily weight gaining, mother
confidence and shorter duration of hospitalization.

Abstract
Background: Birth weight and gestational age are two important variables in obstetric research. The primary measure of gestational age is based on a mother’s recall of her last menstrual period. This recall may cause random or systematic errors. Therefore, the objective of this study is to utilize Bayesian mixture model in order to identify implausible gestational age.
Methods: In this cross-sectional study, medical documents of 502 preterm infants born and hospitalized in Hamadan Fatemieh Hospital from 2009 to 2013 were gathered. Preterm infants were classified to less than 28 weeks and 28 to 31 weeks. A two-component Bayesian mixture model was utilized to identify implausible gestational age; the first component shows the probability of correct and the second one shows the probability of incorrect classification of gestational ages. The data were analyzed through OpenBUGS 3.2.2 and 'coda' package of R 3.1.1.
Results: The mean (SD) of the second component of less than 28 weeks and 28 to 31 weeks were 1179 (0.0123) and 1620 (0.0074), respectively. These values were larger than the mean of the first component for both groups which were 815.9 (0.0123) and 1061 (0.0074), respectively.
Conclusion: Errors occurred in recording the gestational ages of these two groups of preterm infants included recording the gestational age less than the actual value at birth. Therefore, developing scientific methods to correct these errors is essential to providing desirable health services and adjusting accurate health indicators.

Abstract
Background: LBW is an important factor that can affect infant mortality and represents an index of economic and social development. It is expected that an increase in the density of midwives attending family physician programs will lead to a decrease in LBW in health centers. This study aimed to compare the percentage of LBW infants before and after the implementation of the family physician program in health centers with and without an increase in midwives density.
Methods: This cross-sectional study compared the percentage of LBW infants before and after the implementation of family physician programs in rural health centers with and without changes in midwives density in Kurdistan. In this study, we included 668 mothers of 2-month-old children and administered structured interviews in 2005 and 2013. Data were analyzed using the difference-in-differences and the Matchit statistical models.
Results: The Matchit model showed a significant average percentage increase 0.08 (0.006–0.17) in LBW infants born between 2005 and 2013 in health centers where the density of midwives increased compared with those where it remained unchanged. The difference-in-differences model showed that the odds ratio of LBW infants is increased by more than twice among participants who had a history of caesarean section.
Conclusion: The results of this study showed that an increase in the density of midwives in a family physician program did not have an impact on reducing the percentage of LBW infants born between 2005 and 2013, in health centers where the density of midwives augmented compared to those where it remained unaltered; it indicated that the increase in the density of midwives alone was not efficient. On the other hand, the results of our study show an increase in the risk of infants born at a LBW due to caesarean section. It is recommended that obstetricians and gynecologists must strictly control pregnancies and avoid unnecessary termination of pregnancy.

Abstract
Background: Low birth weight (LBW), a crucial determinant of neonatal complications, represents a major public health concern worldwide. Epidemiological research is of crucial importance for designing and implementing ad hoc interventions for this issue, helping and guiding decision- and policy-makers in each country to prevent the increased prevalence of LBW in infants through estimating the prevalence rate, identifying and controlling major risk factors. The present investigation aimed to systematically assess LBW prevalence rate in Iran and its determinants.
Methods: PubMed/Medline via Ovid, Embase, Web of Science and Scopus as well as Magiran, SID and Irandoc were searched from inception until November 2016. Also, the grey literature (via Google Scholar) was mined. The DerSimonian-Laird model was exploited. The I2 and Q-test tests were used to investigate heterogeneity between the studies. Sensitivity and subgroup analyses were performed to ensure the robustness and validity of our findings. Different cumulative meta-analyses were conducted stratifying according to the year of publication and sample size. Any potential bias in publication was assessed carrying out the Egger’s test.
Results: LBW prevalence rate was estimated to be 8% (95%CI: 7-9) in Iran. Sensitivity analysis confirmed the stability of finding. Studies were cumulated by the year of publication, and the results did not change pre- and post-cumulative meta-analysis. No publication bias could be observed.
Conclusion: LBW prevalence rate in Iran is well comparable with the prevalence figures of both developed and developing countries. This could be due to the health reforms implemented in Iran throughout the years.

Abstract
Background: Oropharyngeal colostrum priming (OCP) has been proposed as a potential nutritional option for very low birth weight (VLBW) newborns. This study aimed to determine short-term outcomes of early oral colostrum administration in VLBW neonates.
Methods: This open-label randomized controlled trial was conducted on VLBW neonates admitted to Mahdieh Hospital, Tehran, Iran, between February and December 2022. According to the protocol, all eligible neonates were randomized evenly to the intervention group, which received oral colostrum (OC), and the control group, which received no OC. Finally, short-term outcomes of early OC administration were compared between groups using the independent-samples t test, chi-square, and Fisher exact tests.
Results: Of 80 randomized neonates, 37 and 39 from the intervention and control groups entered the final analysis, respectively. Neonates in the intervention and control groups did not significantly differ in terms of peripherally inserted central catheter (PICC) infection (P = 0.728), sepsis (P = 0.904), necrotizing enterocolitis (NEC) (P > 0.999), intraventricular hemorrhage (IVH) (P = 0.141), retinopathy of prematurity (ROP) (P = 0.923), and bronchopulmonary dysplasia (BPD) (P = 0.633). Furthermore, there was no significant difference between groups considering the time to reach 120 cc/kg feeds (P = 0.557), time to reach birth weight (P = 0.157), length of hospitalization (P = 0.532), and mortality rate (P = 0.628).
Conclusion: The results of our study revealed that despite safety, early OC administration did not improve any of the short-term outcomes in VLBW neonates.

Abstract
Introduction: Twin pregnancy is associated with a high risk of mortality and morbidity. It is necessary to estimate the weight difference of the fetuses with a reliable method to prevent possible complications. This study was conducted to compare the association between the Estimated fetal weight (EFW) discordance and the Abdominal Circumference (AC) discordance with birth weight in twins.
Methods: This was a descriptive-analytical and retrospective study. The statistical population was all twin pregnant mothers referred to Imam Khomeini Hospital in Ahvaz from 2017 to 2019. The sample size was determined with a census (540 people). Based on abdominal circumference (AC), the size of head circumference (HC), femur length (FL), the Biparietal Diameter (BPD), and using the Hadlock formula, estimate of fetal weight(EFW) was calculated. Then the EFW Discordance and AC Discordance were calculated and compared with the birth weight. Data were analyzed using SPSS18. Unpaired, Two-Tailed T-test and Pearson correlation test was used.
Results: The results showed that the mean percentage difference of fetal weight in twin pregnancies in the EFW method was 9.25%, in the AC method was 9.89% and finally at birth was 10.72%. The correlation of the weight difference between the two embryos in the AC method with the time of birth (r = 0.922 and P <0.001) was higher than in the EFW method with the time of birth (r = 0.69 and P <0.001) and finally it was found that in detecting the difference more from 20% and 25%, AC diagnostic power was good, but EFW was moderate.
Conclusion: Therefore, to evaluate the weight and weight difference in twin embryos, the AC
method has the appropriate accuracy and compatibility. Another major prospective study to evaluate the diagnostic performance of AC and EFW mismatch based on gestational age at scan, incision point, maternal and placental characteristics to determine true ultrasound diagnostic accuracy in predicting growth
mismatch in twin pregnancy and optimal post-case management option is needed.
