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

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

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

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

Phenobarbital versus morphine in the management of neonatal abstinence syndrome, a randomized control trial.

BACKGROUNDS: Evaluating the efficacy of the loading and tapering dose of Phenobarbital versus oral Morphine in the management of NAS. METHODS: This randomized, open-label, controlled trial was conducted on 60 neonates born to illicit drugs dependent mothers at Vali-Asr and Akbar-Abadi hospitals, Tehran, Iran, who exhibited NAS requiring medical therapy. The neonates were randomized to receive either: Oral Morphine Sulfate or a loading dose of Phenobarbital followed by a tapering dose. The duration of treatment required for NAS resolution, the total hospital stay and the requirement for additional second line treatment were compared between the treatment groups. RESULTS: The Mean ± Standard Deviation for the duration of treatment required for the resolution of NAS was 8.5 ± 5 days in the Morphine group and 8.5 ± 4 days in the Phenobarbital group (P = 0.9). The duration of total hospital stay was 12.6 ± 5.6 days in the Morphine group and 12.5 ± 5.3 days in the Phenobarbital group (P = 0.7). 3.3 % in the Morphine group versus 6.6 % in the Phenobarbital group required adjunctive treatment (P = 0.5). CONCLUSIONS: There were no significant differences in the duration of treatment, duration of hospital stay, and the requirement for adjunctive treatment, between the neonates with NAS who received Morphine Sulfate and neonates who received a loading and tapering dose of Phenobarbital. TRIAL REGISTRATION: This study is registered at the Iranian Registry of Clinical Trials ( www.irct.ir ) which is a Primary Registry in the WHO Registry Network. (Registration Number = IRCT201406239568N8 ).

An improved method for extraction of high-quality total RNA from oil seeds.

Seeds of oilseed plants that contain large amounts of oil, polysaccharides, proteins and polyphenols are not amenable to conventional RNA isolation protocols. The presence of these substances affects the quality and quantity of isolated nucleic acids. Here, a rapid and efficient RNA isolation protocol that, in contrast to other methods tested, allows high purify, integrity and yield of total RNA from seeds of sesame, corn, sunflower, flax and rapeseed was developed. The average yields of total RNA from 70 mg oil seeds ranged from 84 to 310 µg with A260/A280 between 1.9 and 2.08. The RNA isolated with this protocol was verified to be suitable for PCR, quantitative real-time PCR, semi-quantitative RT-PCR, cDNA synthesis and expression analysis.

Bioinformatics study of delta-12 fatty acid desaturase 2 (FAD2) gene in oilseeds.

Fatty acid desaturases constitute a group of enzymes that introduce double bonds into the hydrocarbon chains of fatty acids to produce unsaturated fatty acids. In plants, seed-specific delta-12 fatty acid desaturase 2 (FAD2) is responsible for the high content of linoleic acid by inserting a double bond at the delta-12 (omega-6) position of oleic acid. In this study, sixteen FAD2 and FAD2-2 protein sequences from oilseeds were analyzed by computational tools including two databases of the NCBI and EXPASY and data management tools such as SignalP, TMHMM, Psort, ProtParam, TargetP, PLACE and PlantCARE. These services were used to predict the protein properties such as molecular mass, pI, signal peptide, transmembrane and conserved domains, secondary and spatial structures. The polypeptide sequences were aligned and a neighbour-joining tree was constructed using MEGA5.1 to elucidate phylogenetic relationships among FAD2 genes. Based on the phylogenetic analysis species with high similarity in FAD2 sequence grouped together. FAD2 proteins include highly conserved histidine-rich motifs (HECGHH, HRRHH and HV[A/C/T]HH) that are located by three to five transmembrane anchors. For further investigations Sesamum indicum FAD2 was selected and analyzed by bioinformatics tools. Analysis showed no N-terminal signal peptide for probable localization of FAD2 protein in cytoplasmic organelles such as chloroplast, mitochondria and Golgi. Instead the C-terminal signaling motif YNNKL, Y(K/N)NKF or YRNKI allows FAD2 protein to selectively bind to and embed in the endoplasmic reticulum. FAD2 promoter contains different cis-regulatory elements involve in the biotic and abiotic stresses response or control of gene expression specifically in seeds.

Evaluation of a new restricted transfusion protocol in neonates admitted to the NICU.

BACKGROUND: Although transfusion is a common procedure for treating anemia of prematurity, there is no specific protocol for blood transfusion in premature newborns. So in this study we investigate whether application of a strict protocol has any statistically significant effect on reduction of blood transfusion. METHODS: In this study, first group admitted in NICU during 2005 - 2006 and the second group admitted during 2006 - 2007. Whereas in the first group the blood transfusion performed based on neonatologists' opinion following consultations with a pediatric hematologist, blood transfusion in the second group was based on the Shannon's protocol. RESULTS: During 2005-2006, out of 206 cases, 71 cases (%34.5) underwent blood infusion. During 2006-2007, out of 211 cases, 56 (%26.5) received blood transfusion based on the Shannon's strict protocol. Although the number of cases decreased, no significant difference was found betweenthe two groups (p= 0.07). Conculsion: Applying strict criteria alone is not effective in reducing the frequency of transfusion in infants.

Production of functional recombinant roseltide rT1 antimicrobial peptide in tobacco plants.

Plant-derived peptides represent a promising group of natural compounds with broad industrial and pharmaceutical applications. Low-efficiency production level is the major obstacle to the commercial production of such bioactive peptides. Today, recombinant techniques have been developed for fast and cost-effective production of high-quality peptides for various applications in the chemical and food industries. The roseltide rT1 is a plant peptide with different antimicrobial properties and therapeutic applications in the prevention and treatment of inflammatory lung diseases by inhibiting human neutrophil elastases. Here, we report the expression of functional recombinant roseltide rT1 peptide in tobacco plants. Transgenic plants were generated by the Agrobacterium-mediated transformation method followed by molecular analysis of transgenic plants to demonstrate successful integration and expression of recombinant rT1 peptide. Protein extracts of transgenic plants expressing a single-copy rT1 gene showed efficient antimicrobial properties as verified by growth inhibition of different bacterial strains. Our results illustrate that plant-derived recombinant rT1 peptide is a promising alternative for rapid and cost-effective production of this important antimicrobial peptide for application in therapeutic and food industries.

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

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

May phytophenolics alleviate aflatoxins-induced health challenges? A holistic insight on current landscape and future prospects.

The future GCC-connected environmental risk factors expedited the progression of nCDs. Indeed, the emergence of AFs is becoming a global food security concern. AFs are lethal carcinogenic mycotoxins, causing damage to the liver, kidney, and gastrointestinal organs. Long-term exposure to AFs leads to liver cancer. Almost a variety of food commodities, crops, spices, herbaceous materials, nuts, and processed foods can be contaminated with AFs. In this regard, the primary sections of this review aim to cover influencing factors in the occurrence of AFs, the role of AFs in progression of nCDs, links between GCC/nCDs and exposure to AFs, frequency of AFs-based academic investigations, and world distribution of AFs. Next, the current trends in the application of PPs to alleviate AFs toxicity are discussed. Nearly, more than 20,000 published records indexed in scientific databases have been screened to find recent trends on AFs and application of PPs in AFs therapy. Accordingly, shifts in world climate, improper infrastructures for production/storage of food commodities, inconsistency of global polices on AFs permissible concentration in food/feed, and lack of the public awareness are accounting for a considerable proportion of AFs damages. AFs exhibited their toxic effects by triggering the progression of inflammation and oxidative/nitrosative stress, in turn, leading to the onset of nCDs. PPs could decrease AFs-associated oxidative stress, genotoxic, mutagenic, and carcinogenic effects by improving cellular antioxidant balance, regulation of signaling pathways, alleviating inflammatory responses, and modification of gene expression profile in a dose/time-reliant fashion. The administration of PPs alone displayed lower biological properties compared to co-treatment of these metabolites with AFs. This issue might highlight the therapeutic application of PPs than their preventative content. Flavonoids such as quercetin and oxidized tea phenolics, curcumin and resveratrol were the most studied anti-AFs PPs. Our literature review clearly disclosed that considering PPs in antioxidant therapies to alleviate complications of AFs requires improvement in their bioavailability, pharmacokinetics, tissue clearance, and off-target mode of action. Due to the emergencies in the elimination of AFs in food/feedstuffs, further large-scale clinical assessment of PPs to decrease the consequences of AFs is highly required.

Assessment of the Complications of Peripherally Inserted Central Catheter in Neonates Admitted to the Intensive Care Unit: A Center's Experience in Iran.

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.

Decoding antibacterial and antibiofilm properties of cinnamon and cardamom essential oils: a combined molecular docking and experimental study.

This study sets out to compare the antibacterial and antibiofilm profiles of Ci/Ca EOs alone and in combination together against infectious bacterial strains. MIC assay was carried out to survey the effectiveness of prepared EOs by two-fold serial dilution method and MTT evaluation. Synergic antibacterial properties of EOs against target strains were studied by using checkerboard titration method. Biofilm growth and development were evaluated using CV and XTT reduction assays. Antibacterial activity was observed for EOs against both bacterial strains with stronger activity for CiEO against both bacteria. The synergistic antibacterial effect was observed only against B. subtilis. Based on the FIC index, combinations could not inhibit the growth of E. coli. The pure EOs and their combination inhibited cell attachment for both studied bacteria with stronger effect on E. coli. CV and XTT reduction assays results showed that Ci EO and its combination with CaEO had the highest antibiofilm activity at lowest MIC value 0.08% and 0.04/0.02% against biofilm formed by E. coli and B. subtilis respectively, indicating a high antibiofilm potential. Computational docking analyses also postulated that the active constituents of evaluated EOs have the potential to interact with different bacterial targets, suggested binding mode of action of EOs metabolites. By and large, synergistic anti-biofilm properties of EOs may provide further options for developing novel formula to inhibit a variety of infectious clinical and industrial strains without (or less) toxicity effects on human body.

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

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

Transient expression of etanercept therapeutic protein in tobacco (Nicotiana tabacum L.).

Etanercept is a recombinant fusion protein of TNFR2 with the Fc portion of human IgG1. Etanercept, an anti-TNF drug, treats autoimmune diseases and improves patients' health. The main goal of the present study was to investigate the possibility of expressing recombinant protein of etanercept in a plant system. For this aim, first a modified version of pCAMBIA1305.1 plasmid with a new multiple cloning site and signal sequence of KDEL for protein secretion was constructed (pCAMBIA1305.1-linker). Then etanercept gene was cloned into the linker fragment of pCAMBIA1305.1-linker vector. Cloning was confirmed by PCR, enzymatic digestion and sequencing techniques. To evaluate the transient expression of the gene, agroinfiltrated tobacco leaves were inoculated with Agrobacterium tumefaciens containing etanercept gene cassette. The recombinant etanercept protein was examined by dot blot and ELISA assays. Our results using anti-human IgG HRP-conjugated antibody confirmed a high level expression of etanercept gene in the tobacco leaves.

Review of the Iranian Newborns' Health, Survival, and Care and Future Challenges.

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.

A study of the validity and reliability of the questionnaire entitled "physicians' approach to and disclosure of medical errors and the related ethical issues".

Medical errors are among the major challenges that threaten patients' health worldwide. The aim of this study was to design a valid and reliable questionnaire to investigate the status of medical error disclosure by physicians. A preliminary questionnaire was developed based on the extracted results from 37 interviews with specialists. To test the validity of the questionnaire, 20 medical practitioners and medical ethics authorities were asked to evaluate the relevance and clarity of each item. To measure the instrument's reliability (the intra-class correlation coefficient and Cronbach's alpha), a test-retest study was conducted on 20 randomly selected physicians twice with a 2-week interval. Statistical analyses were performed using SPSS software version 20. The overall relevance and clarity of the instrument, with an average approach, were measured at 97.22 and 94.03 percent respectively. The Cronbach's alpha, which presents the internal consistency was satisfactory (0.70 - 0.79) for various domains of the questionnaire. The range of intra-class correlation coefficients for the items in all domains of the questionnaire was 0.76 to 1.00. Regarding the validity and reliability of the questionnaire, it can be an appropriate instrument in the assessment and monitoring of the status of medical error disclosure by physicians.

Factors influencing the attitudes of NICU physicians toward care of neonates with very poor prognosis.

Attitudes of physicians toward neonates with poor prognosis greatly influence their decisions regarding the course of treatment and care. The present study aimed to investigate factors contributing to attitudes of medical practitioners toward poor prognosis neonates. This was a cross-sectional, descriptive-analytic study. Questionnaires for assessing subjects' attitudes toward care of very poor prognosis neonates were administered to all neonatologists, pediatricians, neonatology assistants, and pediatric residents (a total of 88 individuals) working in the NICUs of Imam Khomeini Hospital. Participants' attitudes were determined through analysis of responses to seven questions on a 5-point Likert scale ranging from "strongly agree" to "strongly disagree". Presence of anomalies incompatible with an acceptable quality of life, birth weight, gestational age, responses to neonatal diagnostic tests, certain types of diseases, parental marital status and practitioner predictions about patient prognosis were the factors contributing to practitioners' attitude (P-value < 0.005). However, no significant relationship was found in connection with religious beliefs, socioeconomic status, opinions of consulting physicians, hospital treatment protocols, standards of the Association of Neonatal Physicians, and ethics committee expectations (P-value > 0.005). It can be concluded that the attitudes of practitioners toward intensive care of poor prognosis neonates is determined by the medical condition of the neonate rather than socio-demographic characteristics.

The Effects of a Peer-Counseling Program on Increase Rate and Continuity of Lactation in Tehran Nursing Mothers.

Objective: The practice of breastfeeding is considered a blessing since its effects on health are well recognized and applies to both mothers and infants. The objective of this study was to evaluate the effectiveness of peer support and training on breastfeeding initiation, duration and exclusivity. Materials and methods: This community-based clinical trial, (IRCT No: 201504049568N12), was conducted during 2015 in the Municipality of Tehran 19 District. First, a total of 150 mothers with their infants from 4 to 20 months of age were asked to complete a questionnaire, which included the demographic characteristics, educational level, and the type of lactation, the initial age of infant for breastfeeding, and the duration of exclusive breastfeeding. Afterwards, 25 volunteer women were selected for lactation counseling. After 6 months, another sample of 116 nursing mothers in the region who had received peer counseling was selected and questioned through the previously mentioned questionnaire. Finally, the results, which were collected from the behavior of the target population before and after the intervention, were compared. Results: The results of the present study indicated that the nursing mothers who received peer counseling proved to have longer durations of breastfeeding (P-value = 0.039), and higher frequency of first hour initiation of breastfeeding (P-value = 0.003) however, the volunteer counselors were mainly housewives who had lower levels of education (P-value = 0.009) and were younger (P-value = 0.009) than those of untrained control group. Conclusion: The study demonstrated the significant effect of peer counseling on breastfeeding initiation and continuation. It is suggested that lactation training could be initiated during the prenatal period along with the conventional methods of training.

Molecular analysis of Malassezia species isolated from hospitalized neonates.

Malassezia species are a part of the skin microflora of neonates. Under certain circumstances, they can cause diseases ranging from simple pustulosis to lifethreatening fungemia in newborn infants. Little information is available about the epidemiology of Malassezia species in neonates. In the present study, we successfully isolated Malassezia yeasts from 68.7% of hospitalized neonates. Using the polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFPL), M. furfur (88.06%) was identified as the most isolated species, followed in frequency by M. globosa (10.48%), M. obtusa (0.73%), and M. slooffiae (0.73%). Among the variables studied, only a longer stay in the ward resulted in a higher colonization rate. Using multiple logistic regression, only the type of hospital and ward had some effects on the colonization rate. Our results supported the hypothesis that neonates acquire Malassezia flora through direct contact with their mothers or hospital personnel.

An agent based architecture for high-risk neonate management at neonatal intensive care unit.

BACKGROUND: In recent years, the use of new tools and technologies has decreased the neonatal mortality rate. Despite the positive effect of using these technologies, the decisions are complex and uncertain in critical conditions when the neonate is preterm or has a low birth weight or malformations. There is a need to automate the high-risk neonate management process by creating real-time and more precise decision support tools. OBJECTIVE: To create a collaborative and real-time environment to manage neonates with critical conditions at the NICU (Neonatal Intensive Care Unit) and to overcome high-risk neonate management weaknesses by applying a multi agent based analysis and design methodology as a new solution for NICU management. METHODS: This study was a basic research for medical informatics method development that was carried out in 2017. The requirement analysis was done by reviewing articles on NICU Decision Support Systems. PubMed, Science Direct, and IEEE databases were searched. Only English articles published after 1990 were included; also, a needs assessment was done by reviewing the extracted features and current processes at the NICU environment where the research was conducted. We analyzed the requirements and identified the main system roles (agents) and interactions by a comparative study of existing NICU decision support systems. The Universal Multi Agent Platform (UMAP) was applied to implement a prototype of our multi agent based high-risk neonate management architecture. RESULTS: Local environment agents interacted inside a container and each container interacted with external resources, including other NICU systems and consultation centers. In the NICU container, the main identified agents were reception, monitoring, NICU registry, and outcome prediction, which interacted with human agents including nurses and physicians. CONCLUSION: Managing patients at the NICU units requires online data collection, real-time collaboration, and management of many components. Multi agent systems are applied as a well-known solution for management, coordination, modeling, and control of NICU processes. We are currently working on an outcome prediction module using artificial intelligence techniques for neonatal mortality risk prediction. The full implementation of the proposed architecture and evaluation is considered the future work.

The Iranian Neonatal Registry: Primary Results.

BACKGROUND: Neonatal registry network systems are conducted worldwide in order to improve the quality of neonatal care and also to integrate research into daily practice. METHODS: We designed a neonatal registry system and conducted a pilot study in Vali-Asr Hospital to explore its effectiveness to develop an overview of our neonatal status. This study is a report of three years of data registry (2013-2016) in above mentioned system. RESULTS: Data were collected from 3360 neonates admitted to level 2 of neonatal ward, and NICU (level 3) of the Vali-Asr Hospital. Among them, 184 (5.5%) neonates didn't survive. The mean ± SD of gestational age (GA) was 35.92 ± 3.352 weeks and the mean ± SD of the birth weight was 2609.23 ± 829.751 g. CONCLUSION: This pilot study indicated that the neonatal registry system can help us to have a better overview of the performance of neonatal wards, and also to find new aspects of neonatal disorders. In addition, this study showed that neonatal registry is an essential tool to improve neonatal care.
