RESUMO
INTRODUCTION: Caesarean section (C/S) rates have significantly increased across the world over the past decades. In the present population-based study, we sought to evaluate the association between C/S and neonatal mortality rates. MATERIAL AND METHODS: This retrospective ecological study included longitudinal data of 166 countries from 2000 to 2015. We evaluated the association between C/S rates and neonatal mortality rate (NMR), adjusting for total fertility rate, human development index (HDI), gross domestic product (GDP) percentage, and maternal age at first childbearing. The examinations were also performed considering different geographical regions as well as regions with different income levels. RESULTS: The C/S rate and NMR in the 166 included countries were 19.97% ± 10.56% and 10 ± 10.27 per 1000 live birth, respectively. After adjustment for confounding variables, C/S rate and NMR were found correlated (r = -1.1, p < 0.001). Examination of the relationship between C/S rate and NMR in each WHO region resulted in an inverse correlation in Africa (r = -0.75, p = 0.005), Europe (r = -0.12, p < 0.001), South-East Asia (r = -0.41, p = 0.01), and Western Pacific (r = -0.13, p = 0.02), a direct correlation in America (r = 0.06, p = 0.04), and no correlation in Eastern Mediterranean (r = 0.01, p = 0.88). Meanwhile, C/S rate and NMR were inversely associated in regions with upper-middle (r = -0.15, p < 0.001) and lower-middle (r = -0.24, p < 0.001) income levels, directly associated in high-income regions (r = 0.02, p = 0.001), and not associated in low-income regions (p = 0.13). In countries with HDI below the centralized value of 1 (the real value of 0.9), the correlation between C/S rate and NMR was negative while it was found positive in countries with HDI higher than the mentioned cut-off. CONCLUSIONS: This study indicated that NMR associated with C/S is dependent on various socioeconomic factors such as total fertility rate, HDI, GDP percentage, and maternal age at first childbearing. Further attentions to the socioeconomic status are warranted to minimize the NMR by modifying the C/S rate to the optimum cut-off.

Background: Peripherally Inserted Central Catheter (PICC), which is inserted through peripheral veins into the superior or inferior vena cava, is used to inject medications or parenteral nutrition in neonates with long-term hospitalization in the intensive care unit. In this study, we assessed the complications of PICC in neonates admitted to the intensive care unit in hospital. Materials and Methods: In the present retrospective cohort, neonates admitted to the Neonatal Intensive Care Unit (NICU) of Valiasr Hospital during 2015-2018 had been divided into two groups with PICC and without it. Data included the occurrence of septicemia, tachycardia, perforation of large veins, pulmonary hypertension, cardiac tamponade, pericardial effusion, catheter site necrosis, hemorrhage, anemia, pleural effusion, ascites, phlebitis of catheter track and neonatal death, which were collected, using the comprehensive neonatal registry of Valiasr Hospital. Data analysis was performed with regression, mantel-haenszel and independent t-test. Results: Data from 174 neonates with PICC were compared to 207 infants with classic IV-Line. In the exposure group, the gestational age and birth weight were lower. Based on the results of the double logistic regression test, septicemia and hemorrhage in the injection site, independent of other variables, were related to the use of PICC and the risk of septicemia or hemorrhage in the injection site was significantly reduced if PCIC was used (p < 0.01). Conclusions: Using the PICC as a therapeutic procedure in hospitalized neonates in the NICU is a safe method. By improving its replacement skills among physicians and nurses, its side effects are minor and negligible.
RESUMO
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.
RESUMO
INTRODUCTION: Providing, maintaining, and improving the health of newborns is one of the most important goals of the health care system in the Islamic Republic of Iran. On the eve of the 40th anniversary of the Islamic Revolution of Iran, we will review factors affecting the health of Iranian neonates over the past 40 years. METHODS: We investigated the evolution of neonatal health and contributing factors in all reports, documents, and articles published by the Iranian Ministry of Health and Medical Education and the former Iranian Ministry of Health as well as WHO, and UNICEF databases from 1970 to 2018. The main topics of the present study include recent developments in reduction of maternal and neonatal mortality, major measures taken to decrease risk of neonatal death, and future challenges. RESULTS: We have reviewed more than 3500 pages of documents and articles published by authoritative sources before and after the Islamic Revolution. A neonatal mortality rate (NMR) of 9.6 per 1000 in 2017 was recordred in Iran, demonstrating a reduction of over three-quarters compared with the pre-Revolution period. Improved prenatal care and nutrition, tetanus vaccination of pregnant mothers, performance of 96.4% of deliveries by trained individuals, circulation of clinical protocols for the integration of midwifery and maternity services, provision of neonatal resuscitation equipment in delivery rooms, promotion of breastfeeding from the first hour after birth onward, establishing and equipping NICUs, increased training of specialists and sub-specialists, prevention and treatment of infections, increasing awareness in families and family-centered neonatal care focused on neonatal brain development, the Newborn Indivisualized Developmental Care and Assessment Program (NIDCAP) and Kangaroo-Mother Care (KMC) are examples of progress made in neonate healthcare after the Islamic Revolution. CONCLUSION: Despite 8 years of war and a variety of sanctions being imposed against I.R. of Iran, very substantial improvements have been achieved in neonatal health and relevant underlying factors. However, we are still faced with challenges that require the engagement of experts and researchers in neonatal medicine.

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 4.1â¯months (CI 95%: 3.2, 4.99). The meta prevalence of EB up to 4â¯months and 5 to 6â¯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 4â¯months (pâ¯≤â¯0.0001). Among children with anemia and respiratory diseases EB until 5 to 6â¯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 (4.1â¯months) was equal to the lower limit recommended by the World Health Organization (WHO). Overall, the duration of EB until 5 to 6â¯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.

OBJECTIVES: To compare the Conventional, Specified, Expanded and Combined Apgar scoring systems in predicting birth asphyxia and the adverse early neurologic outcomes. METHODS: This prospective cohort study was conducted on 464 admitted neonates. In the delivery room, after delivery the umbilical cord was double clamped and a blood samples was obtained from the umbilical artery for blood gas analysis, meanwhile on the 1- , 5- and 10- minutes Conventional, Specified, Expanded, and Combined Apgar scores were recorded. Then the neonates were followed and intracranial ultrasound imaging was performed, and the following information were recorded: the occurrence of birth asphyxia, hypoxic Ischemic Encephalopathy (HIE), intraventricular hemorrhage (IVH), and neonatal seizure. RESULTS: The Combined-Apgar score had the highest sensitivity (97%) and specificity (99%) in predicting birth asphyxia, followed by the Specified-Apgar score that was also highly sensitive (95%) and specific (97%). The Expanded-Apgar score was highly specific (95%) but not sensitive (67%) and the Conventional-Apgar score had the lowest sensitivity (81%) and low specificity (81%) in predicting birth asphyxia. When adjusted for gestational age, only the low 5-minute Combined-Apgar score was independently associated with the occurrence of HIE (B = 1.61, P = 0.02) and IVH (B = 2.8, P = 0.01). CONCLUSIONS: The newly proposed Combined-Apgar score is highly sensitive and specific in predicting birth asphyxia and also is a good predictor of the occurrence of HIE and IVH in asphyxiated neonates.

BACKGROUND: The aim of this study is to estimate the cost of care and treatment for extremely low birth weight (ELBW) neonates admitted to a teaching and referral hospital. This cost estimation project can help health policy makers and planners make decisions and develop plans for perinatal service staging programs and better management of NICUs (Neonatal Intensive Care Units). METHODS: This cohort study performed on 50 extremely low birth weight neonates (w ≤ 1000gr) born in Vali-e Asr Hospital, Tehran-Iran in the period of March 2012 to September 2013. This teaching and referral hospital had 15 NICU beds as well as an active neonatal growth and development follow-up clinic with a pediatric neurodevelopment specialist during the period of the study. Cases would undergo initial developmental visits and preventative measures immediately after being admitted to the ward. Also after discharge, they were followed up monthly for six months and then every two months, during first year of life. RESULTS: Overalls, 23 newborns -46% of ELBW and 40% of total neonatal mortality rate (that amounted 55) died during hospital stay. Beside hospitalization, the major part of expenses was related to medication and medical supplies. All neonates needing rehabilitation underwent this type of intervention for one year. The mean cost of rehabilitation in neonates with no insurance coverage was 6700 US Dollars per year, which is reduced by half (3350 US Dollars) when covered by insurance. CONCLUSION: Medication, medical supplies and equipment cost was significantly high. This is especially due to the fact that the present types of insurances do not cover such expenses very well, forcing parents to pay themselves. Insurance systems are expected to take this issue into immediate account.
RESUMO
This study was designed to assess the frequency of exclusive breastfeeding in two health centers of Shahid Beheshti University of Medical sciences in Khak Sefid, Tehran, Iran. A total of 175 mothers, referred for the third dose of their infants' DPT vaccination program participated in the study by completing a questionnaire regarding characteristics of their pregnancy, delivery and exclusive breastfeeding within the first six months of birth. Two-variable analysis and logistic regression test were applied to evaluate factors influencing exclusive breastfeeding. Results indicated that the frequency of exclusive breastfeeding, i.e., breastfeeding within the first six months of birth without the use of any other food with or without vitamin supplementation, was 31.17% (95% CI=23.77%-38.57%), which means 48 infants of 154<179 days old Among 154 infants (<179 days old) 48 did not have a history of being separated from their mothers. In logistic regression analysis, the variables which were directly associated with exclusive breastfeeding, with 0.05 significance level of alpha, included breastfeeding within the first hour of birth, eight times or more breastfeeding per day and receiving breastfeeding education during pregnancy. Variables with a negative association with breastfeeding included lack of breast milk, presence of a breast problem that could hinder breastfeeding, bottle feeding, physician or family's advice not to breastfeed and infant's refusal to breastfeed. Frequency of breastfeeding within the six months of birth is less than similar frequencies which are obtained by asking about breastfeeding on the day of the interview. It is recommended to apply real frequency for assessment, evaluation and programming of exclusive breastfeeding during the first six months of birth.

OBJECTIVE: The overall risk of malignancy in ovarian neoplasm is 13% in premenopausal women and 45% in postmenopausal women. Differentiating benign and malignant disease with frozen section is possible during operation; however, information on patients' history, physical examination, paraclinical criteria (tumour markers, imaging) and gross examination of tumour can also be helpful in planing the surgery. METHODS: This study was conducted on 150 women who underwent laparotomy due to adnexal mass between April 2003 and October 2005 at Vali-e-Asr Hospital, Tehran, Iran. Sensitivity and specificity of clinical assessment (history, tumour marker and imaging), gross examination and frozen section were calculated. RESULTS: Based on our findings frozen section had the highest sensitivity for diagnosing malignant tumour comparing with other methods of diagnosis (88.9%). Sensitivity was 71.3% for preoperative clinical examination, 83% for ultrasonography, 89.8% for CT scan, 70% for CA125 and 84.1% for gross examination, likewise the highest specificity was seen for frozen section (93.5%). CONCLUSION: This data confirm that frozen section diagnosis is a reliable method for the surgical management of patients with an ovarian mass, but history of disease, Para clinical criteria and gross examination can help to surgeon to perform on appropriate operation in the areas where frozen section is not possible.
