Clinical cause of neonatal mortality in Iran: analysis of the national Iranian Maternal And Neonatal network

BACKGROUND

The neonatal mortality rate is a main indicator of the health and development of a country. Having insight into the cause of neonatal deaths may be the first step to reducing it. This paper depicts the cause of newborn deaths in Iran.

METHODS

This cross-sectional study was performed on data from the national Iranian Maternal And Neonatal network to investigate all neonatal deaths in the country during the year 2019. The cause of death data were reported according to categories of birth weight, gestational age (GA), death time and place.

RESULTS

The main causes of the 9959 neonatal deaths during the study period were respiratory distress syndrome (RDS) (37%), malformation (21%), prematurity of <26 weeks (20%), others (12%), asphyxia (7%) and infection (3%). The major causes of neonatal mortality in delivery rooms were prematurity of <26 weeks and in the inpatient wards the RDS. By increasing the GA and birth weight towards term babies, the rate of RDS gets lower, while that of malformation gets higher.

CONCLUSIONS

RDS was the main cause of neonatal mortality in Iran which is seen mainly in preterm babies. Prematurity of <26 weeks was another main cause. Thus, suggestions include reducing prematurity by preconception and pregnancy care and, on the other hand, improving the care of preterm infants in delivery rooms and inpatient wards.

Perinatal outcomes and sinopharm BBIBP-CorV vaccination during pregnancy

BACKGROUND

After the outbreak of COVID-19, a huge part of the health care services was dedicated to preventing and treating this disease. In case of COVID-19 infection, severe COVID-19 is reported more in pregnant individuals. Afterward, Vaccination against SARS-CoV-2 became a hot topic due to known effects in preventing severe COVID-19 during pregnancy. Vaccination of pregnant individuals started in August 2021 with the Sinopharm vaccine in Iran. The aim of current study was to determine the incidence of perinatal outcomes in women who were vaccinated during pregnancy.

METHOD

This retrospective cohort study included 129,488 singleton births from March 21, 2021, until March 21, 2022, in Tehran, Iran. The data was obtained from the Iranian Maternal and Neonatal (IMaN) Network and the Maternal Vaccination Registry. Adverse perinatal outcomes investigated in this study include preterm birth, extremely preterm birth, low birth weight, very low birth weight, intrauterine growth restriction, stillbirth, neonatal intensive care unit admission, congenital anomaly, neonatal death and low 5-minute Apgar score. The risk of all perinatal outcomes was evaluated using multiple logistic regression. The analysis was done using STATA version 14.

RESULTS

Of all 129,488 singleton births included in this study, 17,485 (13.5%) were vaccinated against SARS-CoV-2 (all with Sinopharm (BBIBP-CorV)). The exposure to the Sinopharm vaccine during pregnancy caused a significant decrease in the incidence of preterm birth (P =0.006, OR=0.91 [95% CI, 0.85 to 0.97]), extremely preterm birth (P =<0.001,OR=0.55 [95% CI, 0.45 to 0.66]), and stillbirth (P =<0.001, OR=0.60 [95% CI, 0.47 to 0.76]). Exposure to vaccination during the first trimester was associated with an increased risk of preterm birth (P =0.01, OR=1.27 [95% CI, 1.04 to 1.55]) Maternal vaccination during pregnancy was not associated with an increased risk of other adverse perinatal outcomes included in this study.

CONCLUSION

The finding of this population-based study indicated no adverse pregnancy outcome due to vaccination with the Sinopharm vaccine during the second and third trimesters of pregnancy. Overall risk of adverse pregnancy outcomes were lower in the vaccinated individuals compared to the unvaccinated group. Also, vaccination during the first trimester was associated with an increased risk of preterm birth.

Exploring causes of neonatal mortality in south east of Iran: A qualitative study

AIM

Neonatal mortality (NM) is a significant global challenge that has a profound impact on families, particularly mothers. To address this challenge, the first step is to identify its underlying causes. Accordingly, this study aimed to explore the phenomenon by consulting with stakeholders, including mothers and experts.

STUDY DESIGN

This study utilized a qualitative design, conducting in-depth interviews with 16 mothers and 15 healthcare experts to gather information. A conventional content analysis approach was employed to analyze the data.

RESULTS

NM is influenced by personal, systemic, and socioeconomic factors. Personal factors can be further divided into those related to the neonate and those related to the mother. Systemic factors are primarily related to the healthcare system, while socioeconomic factors include low literacy, low income, lack of access to healthcare, and consanguineous marriage.

CONCLUSION

NM is influenced by a wide range of factors that require separate and targeted interventions to reduce its incidence. In the short term, priority should be given to preventable factors that can be addressed through simple interventions, such as screening mothers for urinary tract infections, educating mothers, and preparing them for pregnancy with necessary lab tests and supplements. In the long term, preventing premature birth, addressing maternal addiction, family poverty, and shortages in healthcare equipment and personnel must be thoroughly addressed.

Pregnancy-Related Complications During the COVID-19 Pandemic in Iran

BACKGROUND

The COVID-19 pandemic has profoundly affected healthcare systems worldwide, with significant collateral damage to vulnerable populations, including the perinatal population. This study sought to compare pregnancy-related complications before and during the COVID-19 pandemic in Iran.

METHODS

This retrospective data analysis was performed from February 20 to August 20, 2019 (prior to the onset of the COVID-19 pandemic) and from February 20 to August 20, 2020 (during the pandemic), encompassing the initial wave of the pandemic and the subsequent lockdown. To collect data, we utilized the medical records of 168,358 women obtained from the Iranian Maternal and Neonatal Network, which is a comprehensive electronic health record database management system specifically designed to store information pertaining to maternal and neonatal health.

RESULTS

A total of 168,358 medical records were analyzed, with 87388 (51.9%) and 80970 (48.1%) before and during the pandemic, respectively. The occurrence of pregnancy complications was found to be significantly more frequent during the pandemic compared to the pre-pandemic period. Notably, there was a higher likelihood of experiencing preeclampsia (odds ratio [OR]=1.14, 95% confidence interval [CI]: 1.07‒1.22, P=0.0001) and gestational diabetes (OR=1.14, 95% CI: 1.09‒1.19, P=0.0001) during the pandemic. Furthermore, cesarean section (CS) became more prevalent during the pandemic in comparison to vaginal delivery (OR=1.19, 95% CI: 1.17‒-1.22, P=0.0001).

CONCLUSION

Our findings demonstrated a significant association between the COVID-19 pandemic and an escalation in adverse pregnancy outcomes, notably preeclampsia, gestational diabetes, and CS deliveries. However, further research is warranted to gain a richer understanding of the intricate interplay between the COVID-19 pandemic and pregnancy complications. This is particularly crucial in light of the evolving landscape of new coronavirus variants.

A novel deep learning approach for typhoon-induced storm surge modeling through efficient emulation of wind and pressure fields

Modeling typhoon-induced storm surges requires 10-m wind and sea level pressure fields as forcings, commonly obtained using parametric models or a fully dynamical simulation by numerical weather prediction (NWP) models. The parametric models are generally less accurate than the full-physics models of the NWP, but they are often preferred owing to their computational efficiency facilitating rapid uncertainty quantification. Here, we propose using a deep learning method based on generative adversarial networks (GAN) to translate the parametric model outputs into a more realistic atmospheric forcings structure resembling the NWP model results. Additionally, we introduce lead-lag parameters to incorporate a forecasting feature in our model. Thirty-four historical typhoon events from 1981 to 2012 are selected to train the GAN, followed by storm surge simulations for the four most recent events. The proposed method efficiently transforms the parametric model into realistic forcing fields by a standard desktop computer within a few seconds. The results show that the storm surge model accuracy with forcings generated by GAN is comparable to that of the NWP model and outperforms the parametric model. Our novel GAN model offers an alternative for rapid storm forecasting and can potentially combine varied data, such as those from satellite images, to improve the forecasts further.

Vulnerable newborn types: Analysis of population-based registries for 165 million births in 23 countries, 2000-2021

OBJECTIVE

To examine the prevalence of novel newborn types among 165 million live births in 23 countries from 2000 to 2021.

DESIGN

Population-based, multi-country analysis.

SETTING

National data systems in 23 middle- and high-income countries.

POPULATION

Liveborn infants.

METHODS

Country teams with high-quality data were invited to be part of the Vulnerable Newborn Measurement Collaboration. We classified live births by six newborn types based on gestational age information (preterm <37 weeks versus term ≥37 weeks) and size for gestational age defined as small (SGA, <10th centile), appropriate (10th-90th centiles), or large (LGA, >90th centile) for gestational age, according to INTERGROWTH-21st standards. We considered small newborn types of any combination of preterm or SGA, and term + LGA was considered large. Time trends were analysed using 3-year moving averages for small and large types.

MAIN OUTCOME MEASURES

Prevalence of six newborn types.

RESULTS

We analysed 165 017 419 live births and the median prevalence of small types was 11.7% - highest in Malaysia (26%) and Qatar (15.7%). Overall, 18.1% of newborns were large (term + LGA) and was highest in Estonia 28.8% and Denmark 25.9%. Time trends of small and large infants were relatively stable in most countries.

CONCLUSIONS

The distribution of newborn types varies across the 23 middle- and high-income countries. Small newborn types were highest in west Asian countries and large types were highest in Europe. To better understand the global patterns of these novel newborn types, more information is needed, especially from low- and middle-income countries.

Epidemiology and Clinical Features of COVID-19 Among 4,015 Neonates in Iran: Results of the National Study from the Iranian Maternal and Neonatal Network (IMaN)

Objective The COVID-19 pandemic had a significant impact on pregnant women and neonates in Iran. This retrospective study describes the national experience among neonates having suspected and confirmed SARS-CoV-2 infection following hospital admission to examine the epidemiology, demographic and clinical features. Study Design All nationwide cases of suspected and confirmed neonatal SARS-CoV-2 infection were drawn from the Iranian Maternal and Neonatal Network (IMaN) between February 2020 to February 2021. IMaN registers demographic, maternal, and neonatal health data throughout Iran. Statistical analysis of demographic, epidemiological and clinical data were performed. Results There were 4,015 liveborn neonates having suspected or confirmed SARS-CoV-2 infection that fulfilled the study inclusion criteria identified in the IMaN registry from 187 hospitals throughout Iran. There were 1,392 (34.6%) neonates that were preterm, including 304 (7.6%) less than 32 weeks gestation. Among the 2,567 newborns admitted to the hospital immediately after birth, the most common clinical problems were respiratory distress (1,095 cases; 42.6%), sepsis-like syndrome (355; 13.8%) and cyanosis (300 cases; 11.6%). Of 683 neonates transferred from another hospital, the most frequent problems were respiratory distress (388; 56.8%), sepsis-like syndrome (152; 22.2%), and cyanosis (134; 19.6%). Among 765 neonates discharged home after birth and subsequently admitted to the hospital, sepsis-like syndrome (244 cases; 31.8%), fever (210; 27.4%), and respiratory distress (185; 24.1%) were most frequent. A total of 2,331 (58%) of neonates required respiratory care, with 2,044 surviving and 287 having a neonatal death. Approximately 55% of surviving neonates received respiratory support, compared with 97% of neonates who expired. Laboratory abnormalities included elevations of WBCs, CPK, liver enzymes, and CRP. Conclusions This report adds the national experience of Iran to the list of reports from multiple countries describing their experience with COVID-19 in neonates, demonstrating that newborns are not exempt from COVID-19-morbidity and mortality.

Evaluation of parental stress in neonatal intensive care unit in Iran: a national study

BACKGROUND

More attention is paid to the survival and treatment of the sick infant in the neonatal intensive care unit (NICU) and parental stress is not considered. The purpose of this study was to determine samples of the level of parental stress in the NICU.

METHOD

This study is a descriptive-analytical study in which Parental Stress and General Health were used in an analytical national survey in Iran. The research sample consists of 2456 parents of infants admitted to NICU. The sampling method was multi-stage random. We used 11- item parental stress questionnaire and 28-item general health questionnaire for the data collection.

RESULT

Baloch ethnicity with an average of 11.52 had the highest level of stress. The mean stress score of mothers was higher than fathers. The mean score of all dimensions of physical symptoms, anxiety, social functioning, depression, and total mental health score in mothers was higher than fathers. There was a statistically significant difference in the length of hospitalization in terms of different levels of parental stress scores (p < 0.002). Lack of decisive response to parents was one of the most stressful issues (8.1%).

CONCLUSION

Our result shows mothers' stress was higher than fathers. So that health policymakers should pay attention to stress risk factors to provide appropriate interventions according stress risk factors Future studies should design appropriate interventions to reduce parental stress, especially in high-risk mothers.

Developing patient safety standards for health-care quality promotion in neonatal intensive care units: A mixed-methods Protocol

BACKGROUND

Neonatal intensive care unit (NICU) is one of the accident-prone settings in the health-care system. There is a series of structural and process threats to the safety of infants hospitalized in this unit, which can be prevented by taking the right actions. For this purpose, developing standards based on current knowledge, available resources, and the context that provides care can determine patient injury prevention requirements. Likewise, it can be a source for national development and application of related guidelines and protocols. This study aims to develop patient safety standards in the NICUs of Iran.

MATERIALS AND METHODS

This mixed-methods study will apply the exploration, preparation, implementation, and sustainment framework to develop patient safety standards. In each phase of this framework, a set of activities take place. Exploration is based on the world health organization model to develop standards. Determining the validity and applicability of standards will be done in Phase 2 (Preparation) and Phase 3 (Implementation), respectively. Since the long-term effects are not desired, the fourth phase (Sustainment) will not be considered.

DISCUSSION

Patient safety standards from this study will contribute to efficient and effective, equitable, and high-quality health-care delivery. The application of them will further promote patient safety and the quality of medical care in Iranian NICUs.

The incidence of congenital anomalies in newborns before and during the Covid-19 pandemic

Background

Pregnant women are one of the most vulnerable groups in the Covid-19 pandemic. Due to the lack of knowledge about fetal and perinatal complications following Covid-19 infection, the association of Covid-19 pandemic and congenital anomalies in babies conceived and born during this pandemic is unclear. Current study aimed to investigate the association between the Covid-19 pandemic and congenital birth anomalies in Iran. The population of newborns whose embryonic period coincided with the Covid-19 crises were compared with a similar group born during the pre-Covid-19 period.

Methods

This is a retrospective comparative analysis of congenital birth anomalies in Iran; desired data was extracted from national birth registry database. All registered congenital anomalies in hospital births were compared between two time periods: During Covid-19 (1st November 2020- 28th February 2021) and Before Covid-19 (1st November 2019-29th February 2020). Incidence of congenital anomalies at birth were compared and analyzed between these two time periods.

Results

The incidence of congenital birth anomalies are significantly increased during Covid-19 pandemic compared with before Covid-19 (P value < 0.00001). The number of all types of anomalies has increased in the current pandemic, but the congenital anomalies of the central nervous system (P value = 0.04) and Genitourinary (P value = 0.03) have a larger contribution than before.

Conclusion

Covid-19 pandemic are associated with congenital anomalies at birth. There are several factors in the Covid-19 pandemic which can affect fetal development in the first trimester of pregnancy. Possible reasons include vertical transmission of Covid-19 infection; maternal fever, stress and anxiety; insufficient preconception and prenatal care; neglect of fetal screening; and poverty imposed by this pandemic.

Parents' and healthcare professionals' experiences and perceptions of parental readiness for resuscitation in Iranian paediatric hospitals: a qualitative study

OBJECTIVE

The aim of this study was to examine parents' and healthcare professionals' experiences and perceptions of parental readiness for resuscitation of their child in a paediatric hospital.

DESIGN

This exploratory descriptive qualitative study used content analysis. Participants shared their experiences and perceptions about parental readiness for cardiopulmonary resuscitation through semi-structured and in-depth interviews. MAXQDA 2020 software was also used for data analysis.

SETTING

The setting was two large teaching paediatric hospitals in Iran (Este Azerbaijan and Mashhad).

PARTICIPANTS

Participants were 10 parents and 13 paediatric healthcare professionals (8 nurses and 5 physicians). Selection criteria were: (a) parents who experienced their child's resuscitation crisis at least 3 months prior and (b) nurses and physicians who were working in emergency rooms or intensive care wards with at least 2 years of experience on the resuscitation team.

RESULTS

Participants shared their experiences about parental readiness for resuscitation of their child in four categories: awareness (acceptance of resuscitation and its consequences; providing information about the child's current condition and prognosis), chaos in providing information (defect of responsibility in informing; provide selective protection of information; hardness in obtaining information), providing situational information (honest information on the border of hope and hopeless; providing information with apathy; providing information as individual; dualism in blaming; assurance to parents; presence of parents to better understand the child's situation) and psychological and spiritual requirements (reliance on supernatural power; need for access to a psychologist; sharing emotions; collecting mementos).

CONCLUSION

The results of this study provide insight on the needs of parents and strategies to use to prepare them for their child's resuscitation crisis, which can be used to enhance family centred care practices in paediatric acute care settings.

Cesarean delivery in Iran: a population-based analysis using the Robson classification system

Background

The rise of Cesarean Sections (CS) is a global concern. In Iran, the rate of CS increased from 40.7% in 2005 to 53% in 2014. This figure is even higher in the private sector.

Objective

To analyze the CS rates in the last 2 years using the Robson Classification System in Iran.

Methods

A retrospective analysis of all in-hospital electronically recorded deliveries in Iran was conducted using the Robson classification. Comparisons were made in terms of the type of hospital, CS rate, and obstetric population, and contributions of each group to the overall cesarean deliveries were reported.

Results

Two million three hundred twenty-two thousand five hundred women gave birth, 53.6% delivered through CS. Robson group 5 was the largest contributing group to the overall number of cesarean deliveries (47.1%) at a CS rate of 98.4%. Group 2 and 1 ranked the second and third largest contributing groups to overall CSs (20.6 and 10.8%, respectively). The latter groups had CS rates much higher than the WHO recommendation of 67.2 and 33.1%, respectively. “Fetal Distress” and “Undefined Indications” were the most common reasons for cesarean deliveries at CS rates of 13.6 and 13.4%, respectively. There was a significant variation in CS rate among the three types of hospitals for Robson groups 1, 2, 3, 4, and 10.

Conclusion

The study revealed significant variations in CS rate by hospital peer-group, especially for the private maternity units, suggesting the need for further attention and audit of the Robson groups that significantly influence the overall CS rate. The study results will help policymakers identify effective strategies to reduce the CS rate in Iran, providing appropriate benchmarking to compare obstetric care with other countries that have better maternal and perinatal outcomes.

A Regionalization Model to Increase Equity of Access to Maternal and Neonatal Care Services in Iran

Objectives

Access to maternal and neonatal care services (MNCS) is an important goal of health policy in developing countries. In this study, we proposed a 3-level hierarchical location-allocation model to maximize the coverage of MNCS providers in Iran.

Methods

First, the necessary criteria for designing an MNCS network were explored. Birth data, including gestational age and birth weight, were collected from the data bank of the Iranian Maternal and Neonatal Network national registry based on 3 service levels (I, II, and III). Vehicular travel times between the points of demand and MNCS providers were considered. Alternative MNCS were mapped in some cities to reduce access difficulties.

Results

It was found that 130, 121, and 86 MNCS providers were needed to respond to level I, II, and III demands, respectively, in 373 cities. Service level III was not available in 39 cities within the determined travel time, which led to an increased average travel time of 173 minutes to the nearest MNCS provider.

Conclusions

This study revealed inequalities in the distribution of MNCS providers. Management of the distribution of MNCS providers can be used to enhance spatial access to health services and reduce the risk of neonatal mortality and morbidity. This method may provide a sustainable healthcare solution at the policy and decision-making level for regional, or even universal, healthcare networks.

Implementation Barriers for Practicing Continuous Kangaroo Mother Care from the Perspective of Neonatologists and Nurses

Introduction: Kangaroo mother care (KMC), as a complement to incubator care, is one of the ten recommendations of the World Health Organization (WHO) for the care of preterm infants. The KMC stabilizes the heart rate, improves oxygen saturation, makes weight gain better, and reduces crying in the infant. In order to launch KMC unit, the barriers for implementing this type of care should be recognized.

Methods: This qualitative research was conducted using a focus group discussion and individual semi-structured interview with nurses, doctors, executive and management staff of a neonatal unit of a third level teaching hospital in Tabriz, northwest Iran. The participants were selected using purposeful sampling. Content analysis was used for analyzing data. Data were analyzed by MAXQDA 10 software.

Results: After analyzing data, four main themes were extracted including mother-related barriers, father-related barriers, physician- related barriers, and system-related barriers.

Conclusion: Based on the findings of the research, it seems that in order to facilitate practicing continuous KMC, much emphasis should be placed on training the parents and health care providers. Furthermore, in some cases, reforming the payment system for physicians, providing an instruction for performing continuous KMC, and continuous assessment of hospitals annually are necessary.

Signal Processing of Heart Rate for Predicting Sepsis in Premature Neonates

The heart rate characteristic (HeRO score) is a figure derived from the analysis of premature neonate's electrocardiogram signals, and can be used to detect infection before the onset of clinical symptoms. The United States and Europe accept this diagnostic technique, but we require more tests to prove its efficacy. This method is not accepted in other developed countries so far. The present study aimed to investigate changes in the heart characteristics of two neonates in Akbar Abadi Hospital in Tehran. Experts chose one newborn as a sepsis case, and the other neonate was healthy. The results were analyzed and compared with previous studies. In this research, a group of five neonates was selected randomly from the neonatal intensive care unit, and cardiac leads were attached to them for recording heart rates. We selected two neonates from the five cases, as a case (proven sepsis) and control, to analyze heart rate variability (HRV). Then, we compared the differences in the heart rate of both neonates. Analysis of HRV of these two neonates showed that the pattern of HRV is compatible with reports from US studies. Considering the results of this study, heart rates and their analysis can provide useful indicators for mathematical modeling before the onset of clinical symptoms in newborns.

Probabilistic quantification of tsunami current hazard using statistical emulation

In this paper, statistical emulation is shown to be an essential tool for the end-to-end physical and numerical modelling of local tsunami impact, i.e. from the earthquake source to tsunami velocities and heights. In order to surmount the prohibitive computational cost of running a large number of simulations, the emulator, constructed using 300 training simulations from a validated tsunami code, yields 1 million predictions. This constitutes a record for any realistic tsunami code to date, and is a leap in tsunami science since high risk but low probability hazard thresholds can be quantified. For illustrating the efficacy of emulation, we map probabilistic representations of maximum tsunami velocities and heights at around 200 locations about Karachi port. The 1 million predictions comprehensively sweep through a range of possible future tsunamis originating from the Makran Subduction Zone (MSZ). We rigorously model each step in the tsunami life cycle: first use of the three-dimensional subduction geometry Slab2 in MSZ, most refined fault segmentation in MSZ, first sediment enhancements of seabed deformation (up to 60% locally) and bespoke unstructured meshing algorithm. Owing to the synthesis of emulation and meticulous numerical modelling, we also discover substantial local variations of currents and heights.

Progress towards Every Newborn Action Plan (ENAP) implementation in Iran: obstacles and bottlenecks

Background

Neonatal mortality accounts for more than 47% of deaths among children under five globally but proper care at and around the time of birth could prevent about two-thirds of these deaths. The Every Newborn Action Plan (ENAP) offers a plan and vision to improve and achieve equitable and high-quality care for mothers and newborns. We applied the bottleneck analysis tool offered by ENAP to identify obstacles and bottlenecks hindering the scale-up of newborn care across seven health system building blocks.

Methods

We applied the every newborn bottleneck analysis tool to identify obstacles hindering the scale-up of newborn care across seven health system building blocks. We used qualitative methods to collect data from five medical universities and their corresponding hospitals in three provinces. We also interviewed other national experts, key informants, and stakeholders in neonatal care. In addition, we reviewed and qualitatively analyzed the performance report of neonatal care and services from 16 medical universities around the country.

Results

We identified many challenges and bottlenecks in the scale-up of newborn care in Iran. The major obstacles included but were not limited to the lack of a single leading and governing entity for newborn care, insufficient financial resources for neonatal care services, insufficient number of skilled health professionals, and inadequate patient transfer.

Conclusions

To address identified bottlenecks in neonatal health care in Iran, some of our recommendations were as follows: establishing a single national authorizing and leading entity, allocating specific budget to newborn care, matching high-quality neonatal health care providers to the needs of all urban and rural areas, maintaining clear policies on the distribution of NICUs to minimize the need for patient transfer, and using the available and reliable private sector NICU ambulances for safe patient transfer.

Survival of very preterm infants in the Islamic Republic of Iran: A population-based retrospective cohort study

Background: Estimation of the survival of very preterm infants is necessary to make decisions and design interventions in order to improve their quality of care. This survey aimed to estimate the survival of very preterm infants born at 23 up to 33 weeks of gestational age (GA) in Iran. Methods: This population-based retrospective cohort study included 8536 infants born before 33 weeks of GA, from March 21st to December 22nd 2013 in Iran. The primary data were extracted from the Iranian national maternal and neonatal registration network (IMAN). All infants who have been discharged alive, followed up by telephone contact up to one year after birth. The Kaplan-Meier and Log-rank tests were performed to estimate survival and to compare survivals, respectively, using SPSS version 26 and R 3.5.2 softwares. Results: The overall survival was estimated at 56.70% (95% C.I: 55.60%-57.80%) at the end of the follow-up period. Total death rate was estimated at 43.30% and was significantly decreased with increasing birth weight (p<0.0001). Survival was increased significantly with increasing GA (p<0.0001), from 5.7% at 23 weeks to 79.6% at 32 weeks. The estimated cumulative proportion of death until the end of the neonatal period had a decreasing trend and then had a steady trend until the end of the follow-up period. The hazard ratio of quadruple or more birth and GA were 1.46 (p=0.021) and 0.83 (p<0.001), respectively. Conclusion: The overall estimated survival of very preterm infants was not high. Even with modern perinatal technology and care, early deaths of very preterm infants were still common.

Implementation and effectiveness of continuous kangaroo mother care: a participatory action research protocol

Background

The efficacy of continuous kangaroo mother care (C-KMC) in reducing neonatal mortality and morbidity among low birthweight and premature infants has been confirmed. Despite the recommendations of the World Health Organization, UNICEF, and the Ministry of Health of Iran to use C-KMC for eligible hospitalized neonates, this type of care is not performed due to implementation problems. This protocol aims to describe the design, implementation, and assessment of C-KMC in one tertiary hospital by means of participatory action research.

Methods

The objective of this study is to design and implement a C-KMC program for neonates that will be performed in two phases using a stages-of-change model. The first phase will be conducted in three consecutive activities of designing, implementing, and assessing the introduction of C-KMC. The second phase of the study has a before-and-after design to assess the effectiveness of C-KMC by comparing the length of preterm neonates’ stay in hospital and exclusive breastfeeding at discharge before and after implementing C-KMC.

Discussion

KMC is an important component of neonatal developmental care as part of family-centered care. Applying this type of care requires creating appropriate strategies, budget allocation, and clear and coordinated planning at different levels of the health system. The stages-of-change model is one of the appropriate approaches to the implementation of C-KMC.

The Effect of Home Visit Program Based on the Continued Kangaroo Mother Care on Maternal Resiliency and Development of Premature Infant: A Randomized Clinical Trial

BACKGROUND

Premature birth is a crisis for mothers and affects resilience. Premature babies are at risk for developmental disorders. The Kangaroo Mother Care (KMC) can reduce maternal stress and improve the growth of the baby. This study aimed at assessing the effect of home visit based on the continued KMC on maternal resiliency and development of premature infant.

METHODS

This randomized controlled trial conducted on 50 pairs of mothers and premature babies with gestational age of 26-32 weeks who were admitted to Neonatal Intensive Care Unit of Om-al-Banin Hospital, Mashhad, Iran in 2019. The KMC is practiced routinely for all eligible newborns in this hospital. The experimental group continued the KMC one month after discharge at home and received two home visits. Resiliency of the mothers was assessed in admission, discharge, and one month after discharge with the Connor and Davison questionnaire and the development of the newborns was assessed in two months of adjusted age with Ages and Stages Questionnaire (ASQ). Data analysis was performed using SPSS software version 16 and t-test, Mann-Whitney, ANOVA, Friedman, Chi-square, Fishers exact. The significance level was set at P<0.05.

RESULTS

The resiliency score of the mothers one month after discharge was112.50±5.50 and 76.40±5.60 in the experimental and control groups, which was significantly different (P<0.001). The ASQ development score of the newborns in two months of adjusted age was also significantly higher in the experimental than the control group (280.40±15.60vs223.80±22.00) (P<0.001).

CONCLUSION

The results showed that the home visit program based on the continued KMC was effective in increasing maternal resilience and the development of premature infants. Trial Registration Number IRCT20181121041718N1.

Effect of NIDCAP home care follow-up program of preterm newborns on maternal anxiety and stress

BACKGROUND

Birth of the preterm babies creates a huge amount of stress in mothers and makes it hard for them to contribute to the care of their off springs. The Newborn Individualized Developmental Care and Assessment Program (NIDCAP)is designed to empower the parents in comprehensively caring for their preterm baby after discharge from the hospital. The present research was intended to study the effects of NIDCAP follow up on the stress and anxiety of the mothers.

METHODS

In this clinical trial, 20 mothers of preterm babies with the gestational age of 26 to 32 weeks were studied at Omolbanin Hospital, Mashhad, Iran. The NIDCAP was performed during the hospital stay and two times after discharge. The control group received routine care without the NIDCAP. Anxiety and stress of the mothers were assessed through the Spielberger and Cohen questionnaires. Data were analyzed by Independent t-test, Chi-square and Fisher's Exact test in SPSS 20 software.

RESULTS

At the baseline, there were no statistically significant differences between the experimental and the control group. After the intervention, the average score of anxiety was significantly lower among mothers in the experimental group compared to the control group(P=0.009). NIDCAP and its follow up also reduced the stress of the mothers in the experiment group (P=0.033).

CONCLUSIONS

Implementation of the NIDCAP and its home follow up was effective in reducing the stress and the anxiety of the mothers of preterm babies. Execution of the NIDCAP is recommended to all hospital of the country for mothers of preterm babies.

Stillbirth in Iran and associated factors (2014-2016): A population-based study

Background: Under Every Newborn Action Plan (ENAP), stillbirth rate in every country should be reduced by 12 or fewer per 1000 total births by 2030. The aims of this study were to determine stillbirth rate at national and subnational levels and to investigate its associated risk factors in Iran.

Methods: Using all data from Iranian Maternal and Neonatal Network (IMaN), we calculated stillbirth rate of Iran from 2014-2016. This network registers information of almost all births across the country. The logistic regression was used to estimate the adjusted odds ratio (aOR) with 95% confidence intervals (CIs) for stillbirth.

Results: In 2014, still birth rate was 7.40 per 1000 births. In 2015 and 2016, stillbirth rates were 7.22 per 1000 births and 7.63 per 1000 births, respectively. The most important related factors of stillbirth were preterm birth (aOR= 62.53, 95% CI; 60.77-64.34), sexual ambiguity (aOR= 14.51, 95% CI; 12.76-16.50), and post term birth (aOR= 3.31, 95% CI; 2.66-4.13).

Conclusion: Under Every Newborn Action Plan (ENAP), stillbirth rate in every country should be reduced by 12 or fewer per 1000 total births by 2030. Iran has achieved stillbirth target of ENAP at national level. It is important for the health care system to establish and improve specific and focused policies, interventions, and programs for achieving this target even in the most deprived areas.

Customized birthweight standard for an Iranian population

Objective: To produce a customized birthweight standard for Iran.Method: Retrospective study of a pregnancy database collected from five hospitals across Iran. The cohort consisted of 4994 consecutive term births with complete data, delivered between July 2013 and November 2014. Coefficients were derived using a backwards stepwise multiple regression technique.Results: Maternal height, weight in early pregnancy and parity as well as the baby's sex were identified as significant physiological variables affecting birthweight. Paternal height and weight were also significant although weaker factors. The expected 280-day birthweight, free from pathological influences, of a standard size mother (height 163 cm, weight 64 kg) in her first pregnancy was 3390 g. Pathological factors found to affect birthweight in this cohort included village housing, anemia, preexisting and gestational diabetes and preeclampsia.Conclusion: The analysis confirmed the main physiological variables that affect birthweight in other countries and shows paternal factors also to be significant variables. Development of a country-specific customized birthweight standard will aid clinicians in Iran to distinguish between fetuses that are either constitutionally or pathologically small, thereby avoiding unnecessary interventions, and improving identification of at-risk pregnancies and perinatal outcome.

Clinical Outcomes of High-Risk Infant Follow-Up Program in a Tertiary Care Centre

BACKGROUND

High-risk infant follow-up (HRIF) program is necessary for early detection, timely intervention, and promotion of health outcomes in vulnerable infants, ethically. The present study was carried out to assess the clinical outcomes of the HRIF Program in Alzahra hospital as a tertiary care centre, in Iran.

MATERIALS AND METHODS

In this cohort study, 5840 neonates were born at Alzahra hospital, from June 1, 2011 to 30th February 2012. Among those who were admitted to neonatal intensive care unit (NICU), 253 infants were recruited by census according to HRIs criteria. After doing necessary measurements and family education, information was recorded in HRI health certificate and then entered in the access database for analysis.

RESULTS

From 253 eligible HRIs registered, 241 (95%) infants attended the follow-up clinic after discharge. A total of180 cases were recalled for further visits, 110 of which attended the clinic. Anthropometric indices had an increasing trend in the first 6 months of life. There was no significant relation between ages and stages questionnaire (ASQ) results and infant birth weight, height, and head circumference. The ratios of intraventricular hemorrhage (IVH) and retinopathy of prematurity (ROP) were 8.7% and 3.1%, respectively. The incidence of congenital hypothyroidism was 2:341 in HRIs.

CONCLUSIONS

Although some outcomes, such as ROP, improved in our study compared to similar studies, the findings indicate an impairment of the current follow-up processes and highlight the necessity to modify the current HRIF program. Ethically, we insist on integrating HRIF program in child health services to promote early childhood development.

Assessing staff-oriented care with developmental support approach in Iranian NICUs

BACKGROUND

Regarding improvements in preterm infants' survival rates, it is necessary the improvement of Neonatal Intensive Care Unit (NICUs) status in order to provide comprehensive care. The aim of this study was to assess the aspects of staffing-oriented neonatal care in NICUs affiliated to Universities of Medical Sciences in Iran.

METHODS

This survey is a cross-sectional study which was conducted in 23 NICUs of nine type-1 Universities of Medical Sciences across country. The study checklist contained 39 items in four domains, including "Composition, Philosophy, Training, and Support", "Management", "Resources", and "Transition Systems". Data were gathered through observation and analyzed using Stata software, version 13.

RESULTS

In this study, the mean score of staffing-oriented care was 43.5 of 100. In none of the studied domains, the mean score obtained was not above 50. Among the four domains studied, the highest score was related to "Management", (the mean score of 50 of 100) and the lowest score related to "Resources" (the mean score of 35 of 100).

CONCLUSIONS

Considering the importance of the role of health professionals in the neonatal comprehensive care, and also the low mean score of staffing-oriented care (43.51 out of 100) and also its items in NICUs in this study, it is concluded that more attention is needed for staff-oriented care as well as the strengthening of this dimension of developmental care along with other dimensions, through designing of appropriate interventions to improve the health outcomes of preterm infants.

Assessing infant-oriented care with developmental support approach in Iranian NICUs

INTRODUCTION

Developmental care program is a comprehensive program to reduce secondary effects of NICU and special care on brain development in premature infants. This study aimed to assess neonatal care situation in Iranian NICUs based on developmental approach to design and provide clinical guidelines for daily care for the caregivers and the infant's family.

METHODS

This was a cross-sectional study conducted in NICU_S in Iran. A total of 23 NICUs of 9 Universities of Medical Sciences were investigated. The checklist contains 30 items in 6 domains. Data were analyzed using STATA software, version 13.

RESULTS

The total mean score obtained from all six domains was 31.29 of 100, and in all domains, the mean scores calculated were not above 50. In "supporting infant," "developmental caregiving activities," "supporting the infants' state organization," "providing neonatal pain management," "developmental care approaches in documentation," and "developmental care approaches in NICU staffing," the total mean scores were 34.76, 21.6, 20, 30.18, 31.30, and 50, respectively.

CONCLUSION

The low mean score of infant-centered developmental care implies health staff's focus on neonatal care with at least the quality of care and its impact on development in preterm infants, and inadequate attention to the infant as an active member in care.

Comparison of Breast Crawl Between Infants Delivered by Vaginal Delivery and Cesarean Section

BACKGROUND

Exclusive breastfeeding is the single most cost-effective intervention to reduce infant mortality. Breast crawl (BC) is deemed a natural way for the baby to behave immediately after delivery. BC is the method that may help initiation of breastfeeding in the most natural way. The aim of this study is to compare successful BC between neonates born through vaginal delivery and those born through cesarean section (CS) and factors associated with a positive outcome.

METHODS

Participants were mothers who delivered their babies during the period of October 2012 to December 2013 in Alzahra Hospital in Tabriz, through cesarean or vaginal delivery. Infants were placed prone on their mothers' abdomen after delivery.

RESULTS

Data show that babies delivered through vaginal delivery had significantly more success in BC than babies born through the cesarean delivery (88.01% versus 11.21%). Moreover, babies in the CS group used significantly less time to achieve BC (45 versus 28 minutes).

CONCLUSION

There is a remarkable difference in completion and length of time used to achieve BC between infants with regard to the delivery mode. Encouraging BC in all dyads, especially in cesarean births, may unduly delay the infant's first breastfeed.

The value of serum pro-oxidant/antioxidant balance in the assessment of asphyxia in term neonates

OBJECTIVE

Asphyxia is a major cause of disabilities in term-born infants. Here we have explored the value in HIE (hypoxic-ischemic-encephalopathy) of using a combination of serum pro-oxidant/antioxidant balance (PAB) assay for predicting the prognosis of asphyxia.

METHOD

Ninety term neonates with asphyxia were enrolled and followed up for two years. Serum PAB, demographic/biochemical characteristics of mothers, and their neonates were determined. The Denver II test was used to assess outcomes.

RESULTS

Of the 90 asphyxiated neonates, 47 (52.2%) had a normal outcome and 43 babies (47.8%) had abnormal outcome. Serum PAB levels in neonates with normal and abnormal outcomes were 17.1 ± 9.23 and 48.27 ± 41.30 HK, respectively. A combination of HIE intensity and PAB, compared to other indicators, had a higher predictive-value (95.2%) for outcomes in asphyxiated babies.

CONCLUSION

We demonstrate that PAB in combination with HIE grade may have a better predictive value for the prognosis of asphyxiated babies and predicting future neurologic problems in asphyxiated term infants.

Parental needs in infant's end-of-life and bereavement in NICU: A qualitative study

BACKGROUND AND AIMS

Newborn death is an unexpected outcome for parents. Parents face with several needs in infant end-of-life. The health care team is responsible for meet these needs. This qualitative study aim was to explore of parental needs in infant end-of-life and bereavement.

MATERIALS AND METHODS

For this qualitative study, 24 single semi-structure interviews were done. A qualitative content analysis method was used. Sampling conducted on purposeful with maximum variation in five Neonatal Intensive Care Unit (NICU) environments in Isfahan city. Inclusion criteria for nurses and doctors were having at least one experience of caring for an infant and their family at end-of-life. Inclusion criteria for parents and their families were having at least one infant at end-of-life or had lost their infant for 6 months before in NICU.

RESULTS

Data analysis uncovered two main themes. Family's support needs with two subthemes (family's support needs before infant's death and family's support needs after infant's death) and family's preparatory needs upon infant's death with two subthemes (management of the bad news of infant's death by treatment team and management of the bad news of infant's death by family).

DISCUSSION

Mourning mother's need for her husband's presence by her side, getting hospitalized in a separate room, and management of infant's death news by father and family were among items rarely pointed out in other studies. Exploration of these needs cab be helpful for the health care team for providing care.

Hospital Care for Newborn Babies: Quality Assessment, A Systematic Review

Context:

Neonatal mortality rate is declining globally. The aim of the present study is to identify relevant indicators for assessing newborn care in hospitals by a systematic review.

Evidence Acquisition:

A search on electronic data base and manual searches of personal files for studies on quality indicators of newborn care were carried out. Searching 9 bibliographic databases, we found 85 articles of which 22 exactly related ones were selected and studied. Hand search yielded 1 record were also searched and 2 records were included.

Results:

A list of 87 structure, process and outcome indicators was formulated from the articles. Also 26 excess measures were identified in gray literature. After removing duplicates, and categorizing in 3 domains, 18 measures were input, 41 process and 34 outcome measures.

Conclusions:

These 93 indicators provide a framework for assessing how well the hospitals are providing neonatal care. These measures should be discussed in each context expert panels to address nationally applicable indices of neonatal care and may be adapted for local health settings.

Innovation of High-risk Infants Follow-up Surveillance System in Iran

Background:

Early childhood development is one of the most social determinants of health that must be notified in order to reducing social gap and inequity. In spite of increasingly developing intensive neonatal care wards and decreasing neonatal mortality rate, there is no follow-up surveillance system to identify high-risk infants (HRI) and their health problems for timely intervention after discharge. This study was carried out to design and pilot high-risk infant follow-ups (HRIFs) surveillance system, in Alzahra Hospital, a tertiary level center of Tabriz University of Medical Sciences (TUOMS), in 2012–2013.

Methods:

In this qualitative research after studying international documents, consensus about criteria of HRIs accomplished by focus group discussion. Then, Delphi agreement technique was used to finalizing assessment timetable. In the second phase, we piloted the designed surveillance system in Alzahra Hospital, a tertiary level center of TUOMS. Pilot study was implemented by follow-up team organized in designed model at the first phase of the study. Then, the findings of the pilot study were being assessed by an expert panel. If the members agreed on made decisions, they were being placed on the agenda of the national committee of development care of newborns for final approval.

Results:

High-risk infants follow-up surveillance system was designed in following steps: Defining of evidence-based criteria of HRIs, organizing the follow-up team, regulating the organs and neurodevelopment assessment timetable, publishing a health certificate notebook for HRIs, and designing Access database software for data collection, report and evaluation.

Conclusions:

We designed and piloted HRIFs surveillance system, so this system was institutionalized in Alzahra Hospital, finally. It can be prepared to apply in the whole country, after detecting the quantitative outcomes and developing the program in East Azarbijan.

Design and evaluation of electronic briefs of neonatal intensive care unit in Taleghani hospital, Tabriz, Iran

More than 9 million neonatal deaths are reported through out the world each year happening in the early weeks of life most of which relate to developing countries. Thus it is very important to present a better way to keep the infants healthy which could be possible by accessing accurate information at any time required during hospitalization of infants. Therefore the required data should be collected, stored and analyzed before which is best possible by using computer. The main objective of this research is enabling researchers and clinicians quick access to the data of the babies admitted in NICU. This study involves the stage of developing a system design and its implementation following the evaluation of the electronic records which is done in a query form. By defining the neccessary terminology and designing a data model, the database and user interface are developed by using a programing language and data base tools. Finally, the system has been evaluated by user satisfaction showing to be about 85% As a result we suggest the hospitals take serious in buying the suitable technology for the NICU ward along with teaching the staffs how to work with it.

Conclusion:

Neonatal transport systems in different countries must adapted according to situation and component of each country have different strength and weakness and in implementing a system must attend to geographical conditions, financial ability and access to professionals, health system structure, facilities related to neonatal health care, antenatal services in regain, health care related, health care program about neonates and pregnant women and epidemiological status and mortality and morbidity in deferent locals and regains in countryside.

The Mother-Newborn Skin-to-Skin Contact Questionnaire (MSSCQ): development and psychometric evaluation among Iranian midwives

Background

Despite the benefits of mother-newborn skin-to-skin contact immediately after birth, it has not been universally implemented as routine care for healthy term neonates. Midwifes are the first person to contact the neonate after birth. However, there is evidence that many midwives do not perform mother-newborn skin-to-skin contact. The aim of this study was to develop and psychometrically evaluate an instrument for measuring factors associated with mother-newborn skin-to-skin contact (MSSCQ) based on the PRECEDE-PROCEED model.

Methods

This was a two-phase qualitative and quantitative study. It was conducted during 2010 to 2012 in Tehran, Iran. In the qualitative part, 150 midwives working in labor room participated in 19 focus group discussions in order to generate a preliminary item pool. Then, content and face validity were performed to provide a pre-final version of the questionnaire. In the quantitative phase, reliability (internal consistency and test-retest analysis), validity and factor analysis (both exploratory and confirmatory) were performed to assess psychometric properties of the instrument.

Results

A 120-item questionnaire was developed through the qualitative phase. It was reduced to an 83-item after content validity. The exploratory factor analysis loaded fifteen-factors and three constructs (predisposing, enabling and reinforcing) containing 82 items (38, 18, and 26 statements, respectively) that jointly accounted for 60.61% of observed variance. The Confirmatory factors analysis determined a model with appropriate fitness for the data. The Cronbach’s alpha coefficient showed excellent internal consistency (alpha = 0.92), and test-retest of the scale with 2-week intervals indicated an appropriate stability for the MSSCQ (ICC = 0.94).

Conclusion

The Mother-Newborn Skin-to-Skin Contact Questionnaire (MSSCQ) is a reliable and valid theory-based measurement and now can be used in clinical practice, midwifery and nursing studies.

Comparison of maternal characteristics in low birth weight and normal birth weight infants

Low birth weight is a key determinant in the risk of morbidity and mortality in the neonatal period and during childhood. This unmatched case-control study in Hamadan, Islamic Republic of Iran, compared the characteristics of mothers of low- and normal-birth-weight infants. Maternal sociodemographic data, pregnancy history, anthropometric data and cord plasma zinc level were collected from 134 mothers of low-birth-weight infants and 134 mothers of normal infants at the time of delivery. Significant differences in maternal characteristics namely gravida, parity, body mass index, maternal weight gain during pregnancy and plasma cord blood zinc were found between low- and normal-birth-weight infants. There were no significant differences in maternal age, maternal education, maternal occupation, family income, previous abortion, previous preterm labour, birth Iinterval, type of clinic and place of residence between the 2 groups.

The Effect of Kangaroo Mother Care (KMC) on Breast Feeding at the Time of NICU Discharge

BACKGROUND

Exclusive breastfeeding is one of the most important essential components of Kangaroo Mother Care.

OBJECTIVE

This study was performed to evaluate the effects of KMC on exclusive breastfeeding just at the time of discharge.

PATIENTS AND METHODS

In this cross sectional study, 251 consecutive premature newborns admitted to neonatal intensive care unit (NICU) between May 2008 and May 2009 in Alzahra University Hospital in Tabriz were evaluated. All of candidate mothers were educated for KMC method by scheduled program. Standard questionnaire was prepared by focus group discussion, and mothers filled it prior to infant hospital discharge.

RESULTS

In this study 157(62.5%) mothers performed kangaroo mother care (KMC group) versus 94 (37.5%) in conventional method care (CMC group). In KMC group exclusive breast feeding was 98 (62.5%) vs. 34 (37.5%), and P =.00 in CMC group, at the time of hospital discharge. Receiving KMC, and gestational age were the only effective factors predicting exclusive breastfeeding. Our result indicated that there was a 4.1 time increase in exclusive breastfeeding by KMC, and also weekly increase in gestational age increased it 1.2 times, but maternal age, birth weight, mode of delivery, and 5 minute Apgar score had no influence on it.

CONCLUSIONS

KMC is more effective, and increases exclusive breast feeding successfully. It can be a good substitution for CMC (conventional methods of care). It is a safe, effective, and feasible method of care for LBWI even in the NICU settings.

Randomized controlled trial of two methods of nasal continuous positive airway pressure (N-CPAP) in preterm infants with respiratory distress syndrome: underwater bubbly CPAP vs. Medijet system device

There has been an increasing interest in the application of non-invasive respiratory support in preterm infants, and different types of nasal continuous positive airway pressure (N-CPAP) devices are being used in Neonatal Intensive Care Units (NICUs). The objective of the present study was to compare the duration of CPAP need and possible complications of two methods of (N-CPAP) delivery: Bubble CPAP (B-CPAP) and Medijet (MJ) system device in preterm infants with respiratory distress syndrome (RDS). This prospective randomized clinical trial was performed on 161 preterm infants (28-37 weeks of gestational age) with RDS and eligible for CPAP therapy. The infants were inborn and admitted in a level III NICU of Al-Zahra Teaching Hospital (Tabriz, Iran) from April 2010 to September 2011. All infants were randomized in the first hour of life to B-CPAP or MJ system. Short binasal prongs were used in both groups and CPAP was set at the level of 5-6 cm H2O. The primary outcome of this study was duration of CPAP need (hour). Other outcomes, such as complications of the two methods of N-CPAP, were evaluated using a checklist. Ninety infants were randomized to the MJ system, and 71 were randomized to B-CPAP. The mean gestational age and birth weight were similar in the two groups, as was the duration of CPAP need (44.3 ± 20.64 vs. 49.2 ± 21.2 hours, respectively; p=0.66). Moreover, the probability of complications, such as CPAP failure rate, pulmonary hemorrhage, pneumothorax, intraventricular hemorrhage, abdominal distention, necrotizing enterocolitis, and bronchopulmonary dysplasia, was the same between the two study groups (p>0.05). There was a trend of more hyperemia of the nose in the B-CPAP group in comparison to the MJ system group (10% versus 3.3%, respectively), but the difference was not significant (p=0.08). In conclusion, the MJ system is as effective as B-CPAP in the management of infants with RDS.

Study of intraventricular hemorrhage in VLBW neonates admitted in Al-Zahra Hospital, Tabriz, Iran

INTRODUCTION AND AIM

Intra-ventricular hemorrhage (IVH) is an important predictor of adverse neurodevelopmental outcome. IVH risk factor identification may conduct improvement of quality of care in neonatal intensive care units. The aim of the current study was to determine possible risk factors associated with IVH in VLBW neonates admitted in our hospital.

PATIENTS AND METHODS

All neonates with birth weight below 1500 gr admitted to NICU. Cranial ultrasonography was done for premature neonates weighed <1000 g in 3 to 5 days and in 1 month again. In premature infants weighed >1000 g, sonography was done in 7 days and 30 days of life respectively. If there is any conditions such as apnea, seizure, significant decrease in level of hemoglobin, increased head circumference, increased oxygen consumption, and other significant changes another sonography was done again. Exclusion criteria were cerebral malformations, metabolic disturbances, chromosomal anomalies, central nervous system infection, and genetic syndromes. Data was analyzed by SPSS ver 16.0 (SPSS Inc, Chicago, IL, USA).

RESULTS

In this study 64 cases with IVH and without IVH were included. Mean of gestational age was 28.78 +/- 12.08. From neonates, 54.6% were boys and 45.4% were girls. Vaginal delivery and cesarean section was done in 56 (32.2%) and 118 (67.8%) cases respectively. Mean +/- SD of pH in cases with IVH and without IVH was 7.19 +/- 0.22 and 7.30 +/- 0.12 respectively (p = 0.001). Mean ISD of pco2 in cases with IVH and without IVH was 65.15 +/- 29.89 and 49.88 +/- 40.89 respectively(p = 0.001). Mean of 5th min APGAR score in patients required CPR was 7.36 +/- 1.57 and in patients without CPR was 8.68 +/- 1.25 (P = 0.001). From cases with IVH, hydrocephaly was detected in 20 cases. From cases without IVH, hydrocephaly was detected in 6 cases. Result of chi-square show significant correlation between IVH and prematurity (chi2 = 21.94, df=1, P < 0.001). From cases with IVH, 18 cases (28.1%) expired. From cases without IVH, 11 cases (10%) expired (chi2 = 9.398, df=1, P = 0.002). Results of chi-square test showed that there were a corelation between IVH and PDA, pressure support, surfactant therapy drug administration, vaginal delivery, neonatal resuscitation, and antenatal corticosteroid therapy (p < 0.05). Hyaline membrane disease, history of preclampsia in mother was significantly higher in cases without IVH (chi-square, p < 0.05).

CONCLUSION

PDA, pressure support, surfactant therapy, inotrop drug administration, vaginal delivery, neonatal resuscitation, and antenatal corticosteroid therapy were significantly higher in cases with IVH. Hyaline membrane disease and preeclampsia in mother was significantly higher in cases without IVH.

Pulmonary complications in primary hypogammaglobulinemia: a survey by high resolution CT scan

BACKGROUND

Primary hypogammaglobulinemia disorders are a group of heterogeneous immunodeficiency syndromes with an increased susceptibility to pulmonary complications.

METHODS

The aim of this study was to evaluate the extent of lung abnormalities in primary hypogammaglobulinaemic patients by high resolution computed tomography (HRCT) scan and pulmonary function test (PFT). HRCT and PFT were performed in 22 Iranian patients with primary hypogammaglobulinemia.

RESULTS

Pathological bronchial findings were observed in thirteen patients: three patients showed only peribronchial thickening and the remaining ten patients suffered from both bronchiectasis and peribronchial wall thickening. Mild type of bronchiectasis and peribronchial wall thickening were the most common type, predominantly observed in the right middle and both right and left lower lobe segments of lungs. Although bullae were not found, emphysema, air-trapping, and collapse/consolidation were observed in two patients. Bronchial involvement was mostly limited to 1 up to 5 bronchopulmonary segments; only one HRCT indicated bronchial involvement in more than nine bronchopulmonary segments. Pathological bronchial findings mostly observed in the proximal bronchi; meanwhile the involvement of the distal bronchi was less common. Decreasing FEVI and FVC were observed in 65% and 55% of patients, respectively. There was a significant correlation between the HRCT score and the predicted values by PFT. The delay of diagnosis in patients with bronchiectasis was significantly higher than those without bronchiectasis.

CONCLUSIONS

It seems that the majority of hypogammaglobulinaemic patients suffer from the mild type of bronchiectasis, which is mostly observed in the proximal bronchi of the lower lobe segments. The delay of diagnosis plays an important role in the occurrence of this complication in these patients.

Congenital anomalies in Iran: a cross-sectional study on 1574 cases in the North-West of country

BACKGROUND

At least one congenital anomaly is present in between 1% and 6% of all infants throughout the world. The aim of this study was to document some epidemiological features of congenital anomalies in the North-West of Iran.

METHODS

The study cases (n = 1574) comprised all births registered/notified to three university-hospitals of Tabriz University of Medical Sciences, Iran, from 2000 to 2004.

RESULTS

Total prevalence of congenital anomalies was 165.5 per 10 000 births [95% confidence interval (CI): 157-174]. Genito-urinary tract and kidney defects, anomalies of nervous system and limb anomalies accounted proportionally for more than 65% of anomalies in the region. The total prevalence of congenital anomalies in the study area increased from 104.6 per 10 000 births in 2000 (95% CI: 90-119) to 170.1 per 10 000 births in 2004 (95% CI: 152-189).

CONCLUSIONS

It is concluded that the data from this cross-sectional study of congenital anomalies in the North-West of Iran may be used as the baseline information to establish a population-based registry of birth defects in the area for health care and research purposes.
