Background: The mechanisms by which fetal weight are regulated during pregnancy
are poorly understood. The relation between hormones such as leptin and adiponectin and intrautrine growth is still
under investigation. The aim of this study was to ascertain whether fetal
growth restriction is associated with alterations of leptin and adiponectin concentrations
in venous umbilical cord blood and maternal serum.
Methods: Maternal serum and venous umbilical cord blood leptin
and adiponectin concentrations were determined by ELISA after 36 week of
gestational age in 22 women with uncomplicated singleton pregnancies with AGA fetuses
(group A) and in 22 women with singleton pregnancies complicated by fetal
growth restriction but without fetal distress (group B), all with
normal body mass index and without history of diabetes, hypertention or
maternal cardiac disease.
Results: Venous umbilical cord leptin levels were significantly
lower in group B compared with group A (8.1±0.8ng/ml versus 39.45±6.8ng/ml p=0.001). Venous
umbilical cord adiponectin levels were also significantly lower in group B compared with
group A
(28.8±3.5μg/ml versus 43.6±3.7μg/ml p=0.007). Maternal serum leptin and adiponectin did not differ
between SGA and AGA groups.maternal BMI, gestational age and maternal age did not differ
between these two groups. Neither leptin nor adiponectin correlated with gender
difference.
Conclusion: In this study we confirmed that growth restricted
fetuses show venous umbilical cord blood leptin and adiponectin concentrations
were significantly lower than those in normal fetuses indicating that these two
adipokines have an independent role in growth restriction pathogenesis. Maybe
in future we can administer recombinant human leptin and adiponectin to growth
restricted fetuses for treatment.

Background: Different studies have shown that despite the expanding number of antifungal agents, death rate caused by Aspergillus species has been increased during the recent decades due to drug-resistance occurrence, increased minimum inhibitory concentration (MIC) and cross-resistance among the isolated species. Regarding the lack of effective response to conventional treatments and antifungal susceptibility patterns of the most common isolated Aspergillus species, this study was undertaken to draw a clearer picture in the Iranian setting. Methods: During 13 months from September 2009 to October 2010, 50 clinically isolated Aspergillus cases were identified based on the method described by Klich (2002) and their morphological features. Subsequently, their susceptibility test was carried out according to NCCLS- M38A broth microdilution method. Results: We found that 7.5% of the isolated A. flavus with an MIC>2 µg/ml to amphotericin B were probably clinically resistant types, and 25% of them with an MIC<8 µg/ml to itraconazole were less sensitive isolated species. The isolates were less sensitive to voriconazole too. The MIC range of 9 strains of A. niger and the MIC of one strain of A. fumigatus had increased to all the three medications in comparison with similar foreign studies. Conclusion: In this study we found that the MICs of most isolates were in the range of the reference strains and the MICs of some isolates were in the range of similar foreign studies. In some significant cases, the MICs were beyond the known ranges showing the lower sensitivity of Iranian isolates and their increased MIC patterns.

Background: Normal vaginal delivery is the best method of delivery. Vaginal delivery is followed by the best pregnancy outcomes. Reducing the rate of cesarean delivery has been a health goal for the United States with economic and social advantages. This study has been conducted with aim of maternal and neonatal outcomes of Normal Vaginal Delivery (NVD) and comparing with cesarean delivery. Methods: This descriptive- analytic study was conducted in Ghaem University Hospital in Mashhad during years 2007 until 2013. Five hundred thirty six full term infants aged 3- 14 day, born either by NVD as control group or cesarean delivery as case group par-ticipated in this study. Sampling was a convenient method. The data in questionnaire containing maternal information (maternal age, mode of delivery, maternal weight, du-ration of delivery, duration of maternal hospitalization, let down reflex, breast feeding status) and neonatal information (age, sex, Apgar score, urination frequency and defe-cation frequency) were collected by a researcher. Results: According to the findings of this study, the infant’s age (P=0.425), admission weight (P=0.278), jaundice access (P=0.162), urination frequency (P=0.165), maternal weight (P=0.869) showed no statistically significant difference between two delivery methods. Time of the first breast feeding after childbirth (P=0.000), defecation fre-quency (P=0.000), maternal age (P=0.000), maternal parity (P=0.003), duration of de-livery (P=0.000), duration of maternal hospitalization (P=0.025), feeding position (P=0.029), let down reflex (P=0.012), mastitis (P=0.025) and breast problems (P=0.027) showed statistically significant difference between the groups. It means defecation frequency, duration of maternal hospitalization, Apgar score, mastitis and breast problems were more in cesarean group, but early breast feeding after delivery, duration of delivery, proper breastfeeding position and let down reflex were more in NVD group. Conclusion: The results of this study showed in comparison with cesarean delivery, normal vaginal delivery provides better outcomes in terms of breast problems, breast feeding status, duration of labor and duration of maternal hospitalization for both mother and infant. So, adopting careful instructions in management and administration of deliveries will help the prevalence of making decisions for normal vaginal delivery and the recovery of delivery outcomes.

Background: Jaundice is the most common cause of neonatal admission within the first month after birth. Therefore, by identifying the causes of jaundice based on the infant’s age at disease onset and age at hospital admission and providing the required training, jaundice can be managed and its associated complications can be prevented. This study was performed to evaluate the causes of neonatal jaundice, based on the infant’s age at disease onset and age at hospital admission.
Methods: In this cross-sectional study, out of 3,130 infants with jaundice, referring to Ghaem Hospital, Mashhad, Iran, from 2003 to 2015, 2,658 newborns were selected. Causes of jaundice are determined based on hematocrit, direct and indirect bilirubin, Coombs test, reticulocyte count, blood group and Rh of mother and neonate, thyroid tests, glucose-6-phosphate dehydrogenase (G6PD) enzyme testing, urinalysis, urine culture, and If necessary, Na, blood urea nitrogen, creatinine and other tests depending on the doctor's supervision. After confirming jaundice in infants, based on the physician’s diagnosis and laboratory results, a researcher-made questionnaire including the infant’s characteristics, was completed.
Results: Based on our study, 27.9% of infants had identified as causes of jaundice. Known causes of jaundice were blood group incompatibility (40%), infection (19%), G6PD enzyme deficiency (12%), endocrine disorders (8%), neonatal hypernatremic dehydration (7%), polycythemia (6%), congenital heart disease (CHD) (4%), occult bleeding (3%) and Crigler-Najjar syndrome (2%). The most common time of hospital admission of jaundice was 4-6 days after birth due to blood incompatibilities, occult bleeding, endocrine disorders, hypernatremic dehydration, CHD, polycythemia and G6PD enzyme deficiency. Moreover, the most common time of admission due to infection was after the first week of birth.
Conclusion: The most common age of onset of jaundice was first three days of birth for blood incompatibility, although they were admitted two days later. Therefore, neonatal admission at appropriate time at onset of jaundice and receiving prompt treatments can reduce the probable complications (e.g., kernicterus).

Background: Hyperbilirubinemia is the most common cause for readmission in the early neonatal period 5 to 36 percent of healthy term infants who are discharged from hospital are again hospitalized due to severe to moderate hyperbilirubinemia. Detection of major and minor risk factors associated with neonatal jaundice helps to identify high-risk infants and prevent neonatal jaundice. This study was performed aiming to evaluate the major and minor risk factors associated with jaundice in infants hospitalized. Methods: This cross-sectional study was performed on 2207 term infants (<15 days) with hyperbilirubinemia (>15 mg/dl) in neonatal clinic or emergency unit or neonatal intensive unit, of Mashhad Ghaem Hospital, Iran, from April 2010 to May 2016. The jaundice of infants was confirmed by the pediatrician and laboratory tests. Then the researcher-made questionnaire containing maternal information and neonatal characteristics was completed. Values were expressed as mean±SD. Student t-test and Mann-Whitney test were used as appropriate. P-value less than 0.05 was considered significant. Results: Sixty one percent of neonates had major risk factors and 80% of neonates had minor risk factor for jaundice. For neonatal jaundice, the most common major risk factors were significant weight loss (27.5%), jaundice visible in the first 24 hours (16.3%), history of treatment with phototherapy and exchange transfusion in sibling (14.8%), Gestational age of 35 to 36 week (9.9%), ABO incompatibility (9.2%), RH incompatibility (3.3%) and G6PD deficiency (3.33%), and the most common minor risk factors were age over 25 years (51.4%), male (49.7%), history of hyperbilirubinemia in sibling (22.3%), diabetic mother's infants (1.5%). Conclusion: The major risk factors for neonatal hyperbilirubinemia were significant weight loss, jaundice visible in the first 24 hours, history of treatment with phototherapy and exchange transfusion in sibling, gestational age of 35 to 36 week, ABO incompatibility, RH incompatibility and G6PD deficiency. |

Methods: In this cross-sectional study, among 2,800 infants with jaundice in Ghaem hospital in Mashhad during the 2007 to 2014, features of 59 infants of diabetic mother's (case group) and 78 infants with unknown jaundice (control group) were analyzed. After confirming of jaundice (Bilirubin ≥ 17 mg/dl) in newborns based on examination of pediatrician and laboratory results, a researcher made questionnaire containing maternal demographic data, (maternal age, parity, maternal problems during pregnancy, route of delivery). Also neonatal characteristics including age, sex, birth weight, current weight, duration of hospitalization, current age, age of recovery and laboratory data (Bilirubin, direct bilirubin, hematocrit, platelet, sodium, potassium, blood urea nitrogen, Cr, TSH, T4) were assessed. After data collection and recording information in SPSS software, version 19.5 (IBM SPSS, Armonk, NY, USA), by using tables, charts and statistical indices, the study was evaluated. Data were analyzed using statistical tests such as Mann-Whitney, Chi-square tests after normality control. Comparison of the two groups in normal distribution with t-test and for non-standard data with Mann-Whitney test. Also for definitive variables Chi-square test was used. P-value less than 0.50 was the significant level minimum.
| Results: In this study, the prevalence of jaundice due to maternal diabetes was 2.10 percent. Birth weight (P=0.02), current age (P=0.003), parity (P=0.000), maternal age (P=0.000), age of recovery (P=0.04), cesarean section (P=0.001), prematurity (P=0.000), maternal problems during pregnancy (P=0.000), abnormal physical examinations (P=0.001) in diabetic mother's infants and Bilirubin (P=0.000), length of hospitalization (P=0.003), in infants with unknown jaundice were higher. Conclusion: The infant of diabetic mother are at increased risk of maternal and neonatal complications. Neonatal complications consist of high birth weight, preterm labor, more jaundice and late recovery, abnormal physical examinations. Also, maternal complications during pregnancy and cesarean section were high. |

Methods: In this descriptive-analytical study, 1347 newborns with the jaundice hospitalized in neonatal clinic or emergency unit or neonatal intensive units of Ghaem Hospital, Mashhad, during May 2011 to November 2017 were investigated. The data collection tool was a researcher-made questionnaire containing three parts. First part was maternal demographic information (age, long hospitalization, and mode of delivery), Second part was neonatal information (serum bilirubin, hematocrit and platelet) and third part was laboratory information (serum bilirubin, hematocrit, and platelet). The relationship between the severity of jaundice in hospitalized infants and maternal hospitalization duration were evaluated. Values were expressed as mean±SD. Student t-test, chi-square and Pearson coefficient tests were used as appropriate. P-value less than 0.05 was considered significant.
Results: 752 (fifty six percent) of mothers are discharged from the hospital at the end of first day. The mean maternal hospitalization duration was 1.31±0.57 days in normal delivery and 1.73±0.65 days in cesarean delivery (P=0.000). Pearson correlation test showed that increasing the duration of maternal hospitalization, some issues were observed including as decreasing serum bilirubin level (P=0.000) in newborns, increasing the admission age in hospital (P=0.045), decreasing daily weight loss rate (P=0.012) and decreasing the percentage of daily weight loss (P=0.002).
Conclusion: By increasing the hospitalization duration of the mother in hospital, serum bilirubin level, rate and percentage of daily weight loss in the newborns would be decreased.

Methods: A cross-sectional study was conducted on 167 patients with breast cancer diagnosed between March 2012 and March 2015 at Shahid Beheshti of Babol, Shahid Rajaei of Tonekabon and Imam Sajad of Ramsar hospitals. A researcher-made questionnaire was used to collect information on the patients and pathology report of tumor and lymph nodes was completed.
Results: The rate of axillary lymph node involvement was observed in 117 patients (70.1%). Mean age was 49.64±11.62 years in the patients with breast cancer. The highest frequency of lymph node involvement was observed in the 40-49 age group (24%). The average size of tumor was 3.39 cm and the majority of patients had a tumor 2-5 cm (T2) but the most involvement was related to T3 (>5cm). The most common type of cancer and grading were invasive ductal carcinoma (93.4%) and tumor grade 2 (52.1%), respectively. Most lymph node involvement was observed in invasive ductal carcinoma and 85.1% of patients had tumor degree 3. 22.2% of patients with vessels involvement had axillary lymph node involvement. 63% of patients’ tumors had receptors of estrogen and progesterone. A statistically significant association was observed between axillary lymph node involvement and tumor size (P=0.031), tumor type (P=0.007), tumor grade (P=0.011), estrogen receptor (P=0.008) and progesterone receptor (P=0.038).
Conclusion: There was a statistically significant association between axillary lymph node involvement and tumor size, type and grade, estrogen and progesterone receptor status, but there was no statistically significant association between axillary lymph node involvement and age and estrogen as well as progesterone receptor status.

Methods: This cross-sectional study was performed on 324 neonates including 120 neonates with normal body temperature and 204 neonates with fever due to dehydration (hyperthermia) referred to Ghaem Hospital in Mashhad, Iran from 2017 to 2019, using a convenience sampling method and a researcher-made questionnaire. Infants presenting with elevated body temperature and having an axillary temperature above or equal to the rectal temperature and with no clinical or laboratory evidence of infection were considered as fever due to dehydration (case group). Infants who were referred for a routine examination or had jaundice but did not require treatment were considered as controls. Infant characteristic (neonatal age, sex, Apgar score, defecation frequency, the first defecation, breastfeeding frequency, urinary frequency, duration of feeding, birth weight, daily weight loss, daily weight loss percentage, lethargy, irritability, mucosal dryness, status fontanelles, hyperthermia, convulsion, apnea, decreased consciousness and infant hospitalization) and maternal information (age, weight, parity, hospital stay, breast problems, mode of delivery, breastfeeding position, delayed breastfeeding, and pregnancy problems. The data were analyzed using Student’s t-test, Chi-square and SPSS software, version 20 (IBM SPSS, Armonk, NY, USA).
Results: In dehydration fever of newborn, admission weight, frequency and duration of feeding, defecation frequency, maternal age were low, but time to first feeding were high (P<0.05). In fever of dehydration: restlessness, mucosal dryness, fontanel status, seizure, apnea, decreased consciousness, breastfeeding with traditional remedies, inappropriate breastfeeding position, lack of let-down reflex, delayed onset of lactation, breast problems and jaundice were more frequent.
Conclusion: Infants with fever of dehydration were more likely to weight loss, delayed in first feeding, shorter feeding times and lower duration of feeding, higher sodium, urea, creatinine, and blood glucose levels. According to the results of this study, breast problems, inappropriate breastfeeding position, absence of reflux, delayed lactation, less frequent breastfeeding, consumption of breast milk with dextrose, manna, and clay tap were risk factors for dehydration fever.

Methods: This cohort study was performed based on the information of the Isfahan Diabetes Prevention Plan (IDPs). This project was implemented from April 2004 to March 2018 in the clinics of the Endocrine and Metabolism Research Center of Isfahan. The subjects in this study include 1228 pre-diabetic patients who participated in this project. Demographic and clinical variables of patients including blood sugar and lipid-blood variables were obtained using a questionnaire and laboratory measurements. Also in this study, the number of clinical variables was recorded 3 times. Data analysis was performed using the latent class growth trees model in R software version v4. (R v4.1.0)
| Results: The mean (standard deviation) age of participants was 44 (6.86) years. Subjects were classified into two classes of low-risk impaired blood sugar (n=1165) and high-risk impaired blood sugar (n=63) based on the trend of changes in blood sugar levels. Blood sugar levels were reported in the first class (104.28) and the second class (132.41). Conclusion: In the present study, it was concluded that there is a significant relationship between the incidence of diabetes and the different classes formed based on the course of changes in blood sugar of at-risk individuals. Therefore, by classifying people at risk, the incidence of this disease can be predicted and thus prevented. Also,measures such as managing the blood sugar and lifestyle variables of pre-diabetic patients through nutrition counseling classes and regular periodic tests can be used to reduce the incidence of diabetes in the future is used in people with pre-diabetes who are at high risk for the disease. |

Methods: The present study is a cross-sectional study that was performed on 2847 icteric neonates over 35 weeks admitted to Ghaem Hospital in Mashhad from May 2014 to May 2021. This study is done by available sampling. After confirmation of jaundice in infants, data were recorded using a researcher-made checklist including maternal demographic information (maternal age, mode of delivery), complete infant characteristics (age, birth weight, age at onset of jaundice, jaundice recovery age) and laboratory findings (Bilirubin, Indirect Coombs, direct Coombs, G6PD), and neonatal development up to two years of age was performed based on the Denver 2 test. Then data analysis was performed by SPSS software using Chi-square test and Student’s t-test.
|
Results: 1642 infants (57.7%) were boys and 1205 infants (42.3%) were girls. Mean and standard deviation of bilirubin in values less than 20 mg/dl in boys was 17.20±2.48 mg/dl and in girls was 16.54±2.80 mg/dl (P=0.000), birth weight was 3.16±0.49 (kg) for boys and 3.07±0.45 for girls (P=0.000). In two groups of male and female infants, age (P=0.004), direct bilirubin (P=0.001), direct and indirect Coombs (P=0.000), and G6PD enzyme deficiency (P=0.000) had a significant difference. Acute kernicterus was reported in 25 (2.03%) boys and 4 (0.46%) girls (P<0.001). In the two-year follow-up, 23 boys (1.9%) and 11 girls (1.28%) had developmental delay (P<0.05).
Conclusion: The incidence of jaundice in male infants was higher than female infants, which is probably due to a higher prevalence of G6PD deficiency in boys. The severity of jaundice was higher in boys less than 20 mg/dl. Jaundice has a worse prognosis in male infants. |
Volume 80, Issue 8 (November 2022)
Methods: The present study is a cross-sectional study that was performed on 729 neonates suspected of infection, in neonatal ward in Ghaem Hospital of Mashhad since May 2015 to May 2022 by available sampling. The data collection tool was a researcher-made checklist containing neonatal characteristics (gestational age, birth weight, first and fifth minute Apgar score, and neonatal status at discharge) and laboratory information (White Blood Cell, Platelet (PLT), C-reactive Protein, Blood culture, Cerebrospinal fluid culture). Infants with congenital infection, congenital anomaly and positive blood cultures without clinical and laboratory symptoms were excluded from the study. Neonatal prognosis was compared in terms of death or discharge among neonates with and without definitive infection. First, we described the results using statistical tables and graphs, and then, data were analyzed by Kolmogorov-Smirnov, T test and SPSS software, version 26 (IBM SPSS, Armonk, NY, USA). P<0.05 considered as significant.
|
Results: According to the results of this study, low birth weight and lower gestational age and lower Apgar score increase the risk of neonatal death. About one-fifth of infants died of definitive infection. The cases of death due to infection in the group of deceased infants were about 4 times higher than in the group of discharged infants. About one third of the babies with sepsis and half of the babies with meningitis died. Forty-four percent of infants with early sepsis and 40% of infants with late sepsis died. In cases of neonatal death due to sepsis, the most common gram-negative infectious agent was Acinetobacter and the most common gram-positive infectious agent was Enterococcus.
Conclusion: Neonatal definitive infection worsens their prognosis. So, the risk of neonatal death increases by 5 times. The probability of death in meningitis is more than sepsis and in early sepsis is more than late sepsis and in sepsis due to gram-negative is more than gram-positive. |
Volume 80, Issue 10 (January 2023)
Methods: This study was a cross-sectional study. The present study was performed on 600 preterm infants with mothers with diabetes, hypertension, preeclampsia, hypothyroidism and epilepsy. This study was done in Ghaem Hospital of Mashhad from March 2015 to April 2021 with available sampling. The data collection tool was a researcher-made checklist including infant (gestational age, Apgar score of the first minute, Apgar score of the fifth minute) and maternal (mode of delivery, prenatal care, premature rupture of the membranes) characteristics. Neonatal prognosis was compared at birth. All clinical and diagnostic examinations of newborns were performed by a neonatologist. Neonatal and maternal data in the group of newborns with normal mothers and newborns with maternal diseases were analyzed by Kolmogorov-Smirnov and Chi-square tests. The significance level was considered p≤0.05 in all cases.
|
Results: The results show that 161 newborns (28.90%) had normal mothers, 89 newborns (15.98%) had diabetic mothers, 117 newborns (21.01%) had hypertensive mothers, and 50 newborns (8.98%) had hypothyroid mothers. One hundred tweny newborns (21.72%) had mothers with preeclampsia, 19 newborns (3.41%) had mothers with epilepsy. Newborns with mothers with epilepsy had the lowest Apgar score of the first minute and the lowest gestational age and newborns with mothers with diabetes had the lowest Apgar score of the fifth minute. Mothers with hypothyroidism had the highest rate of premature rupture of the membranes and mothers with hypertension and preeclampsia had the highest incidence of cesarean section.
Conclusion: Maternal diseases including diabetes, hypertension, preeclampsia, hypothyroidism and epilepsy affect the prognosis of neonates in terms of the severity of prematurity, premature rupture of the membranes, type of delivery, Apgar scores of the first and fifth minutes. Therefore, proper control and treatment of these diseases may improve neonatal prognosis. |
