Risk Of Sudden Infant Death Syndrome Research Articles

Association between risk of infant death and birth-weight z scores according to gestational age: A nationwide study using the Finnish Medical Birth Register.

To investigate the association between infant mortality and birth weight using estimated fetal weight (EFW) versus birth-weight charts, by gestational age (GA). This nationwide population-based study used data from the Finnish Medical Birth Register from 2006 to 2016 on non-malformed singleton live births at 24-41+6 weeks of gestation (N = 563 630). The outcome was death in the first year of life. Mortality risks by birth-weight z score, defined as a continuous variable using Maršál's EFW and Sankilampi's birth-weight charts, were assessed using generalized additive models by GA (24-27+6, 28-31+6, 32-36+6, 37-38+6, 39-41+6 weeks). We calculated z score thresholds associated with a two- and three-fold increased risk of infant death compared with newborns with a birth weight between 0 and 0.675 standard deviations. The z score thresholds (with corresponding centiles in parentheses) associated with a two-fold increase in infant mortality were: -3.43 (<0.1) at 24-27+6 weeks, -3.46 (<0.1) at 28-31+6 weeks, -1.29 (9.9) at 32-36+6 weeks, -1.18 (11.9) at 37-38+6 weeks, and - 1.34 (9.0) at 39-41+6 weeks according to the EFW chart. These values were - 2.43 (0.8), -2.62 (0.4), -1.34 (9.0), -1.37 (8.5), and - 1.43 (7.6) according to the birth-weight chart. The association between birth weight and infant mortality varies by GA whichever chart is used, suggesting that different thresholds for the screening of growth anomalies could be used across GA to identify high-risk newborns.

New Step in Understanding the Pathogenetic Mechanism of Sudden Infant Death Syndrome: Involvement of the Pontine Reticular Gigantocellular Nucleus.

This study aimed to investigate, for the first time, the potential role of the gigantocellular nucleus, a component of the reticular formation, in the pathogenetic mechanism of Sudden Infant Death Syndrome (SIDS), an event frequently ascribed to failure to arouse from sleep. This research was motivated by previous experimental studies demonstrating the gigantocellular nucleus involvement in regulating the sleep-wake cycle. We analyzed the brains of 48 infants who died suddenly within the first 7 months of life, including 28 SIDS cases and 20 controls. All brains underwent a thorough histological and immunohistochemical examination, focusing specifically on the gigantocellular nucleus. This examination aimed to characterize its developmental cytoarchitecture and tyrosine hydroxylase expression, with particular attention to potential associations with SIDS risk factors. In 68% of SIDS cases, but never in controls, we observed hypoplasia of the pontine portion of the gigantocellular nucleus. Alterations in the catecholaminergic system were present in 61% of SIDS cases but only in 10% of controls. A strong correlation was observed between these findings and maternal smoking in SIDS cases when compared with controls. In conclusion we believe that this study sheds new light on the pathogenetic processes underlying SIDS, particularly in cases associated with maternal smoking during pregnancy.

Dysregulation of platelet serotonin, 14–3–3, and GPIX in sudden infant death syndrome

Sudden infant death syndrome (SIDS) is the leading cause of post-neonatal infant mortality, but the underlying cause(s) are unclear. A subset of SIDS infants has abnormalities in the neurotransmitter, serotonin (5-hydroxytryptamine [5-HT]) and the adaptor molecule, 14–3–3 pathways in regions of the brain involved in gasping, response to hypoxia, and arousal. To evaluate our hypothesis that SIDS is, at least in part, a multi-organ dysregulation of 5-HT, we examined whether blood platelets, which have 5-HT and 14–3–3 signaling pathways similar to brain neurons, are abnormal in SIDS. We also studied platelet surface glycoprotein IX (GPIX), a cell adhesion receptor which is physically linked to 14–3–3. In infants dying of SIDS compared to infants dying of known causes, we found significantly higher intra-platelet 5-HT and 14–3–3 and lower platelet surface GPIX. Serum and plasma 5-HT were also elevated in SIDS compared to controls. The presence in SIDS of both platelet and brainstem 5-HT and 14–3–3 abnormalities suggests a global dysregulation of these pathways and the potential for platelets to be used as a model system to study 5-HT and 14–3–3 interactions in SIDS. Platelet and serum biomarkers may aid in the forensic determination of SIDS and have the potential to be predictive of SIDS risk in living infants.

Changes in Tryptophan Hydroxylase 2 and 5HT1A Receptor Density May Contribute to Developmental Variation in Response to Serotonin in the in vitro Bullfrog Brainstem

Bullfrog, Lithobates catesbeiana, is a vertebrate animal model that can be used to study toxicology and developmental physiology. Our research is focused on better understanding vulnerability to brainstem respiratory centers in the pathology of sudden infant death syndrome (SIDS). We propose that a link between nicotine exposure during development leads to changes in the serotonergic signaling cascades of respiratory coordinating neurons. Caudal raphe neurons send serotonergic fibers that arborize and terminate directly on or near respiratory neurons in the brainstem. In bullfrogs, serotonin elicits a developmentally dependent effect on respiratory motor output. Late metamorphic tadpoles demonstrate an increase in lung burst activity with exposure to low concentrations of serotonin (≤ 0.5μM 5-hydroxytryptamine; 5-HT) mediated in part by 5-HT1a receptor (5HT1aR) activation. This developmental change in activity may be due to changes in the number of serotonergic fibers and/or 5-HT1a receptor density. Using the NIH Basic Local Alignment Search Tool (BLAST) we compared human and bullfrog 5HT1aR and tryptophan hydroxylase 2 (TH2) protein sequences and found a 34 and 65 percent identity match respectively. Quantitative western blot analysis of both proteins indicates developmental shifts in the serotonergic network during metamorphosis. These results were supported by immunohistochemical staining of 5HT1aR and TH2 in caudal raphe containing brainstem sections from pre-metamorphic tadpoles and post-metamorphic frogs. Impairments in the maturation of this serotonergic network may underlie the toxidrome associated with developmental nicotine exposure and further support the increased risk of SIDS following that exposure. This research was supported by the University of Wisconsin- La Crosse (UWL) through support from the UWL College of Science and Health, two UWL Undergraduate Research Creative Grants and a UWL FY23/24 Faculty Research Grant.

Prenatal and postnatal factors associated with sudden infant death syndrome: an umbrella review of meta-analyses.

Comprehensive quantitative evidence on the risk and protective factors for sudden infant death syndrome (SIDS) effects is lacking. We investigated the risk and protective factors related to SIDS. We conducted an umbrella review of meta-analyses of observational and interventional studies assessing SIDS-related factors. PubMed/MEDLINE, Embase, EBSCO, and Google Scholar were searched from inception until January 18, 2023. Data extraction, quality assessment, and certainty of evidence were assessed by using A Measurement Tool Assessment Systematic Reviews 2 following PRISMA guidelines. According to observational evidence, credibility was graded and classified by class and quality of evidence (CE; convincing, highly suggestive, suggestive, weak, or not significant). Our study protocol was registered with PROSPERO (CRD42023458696). The risk and protective factors related to SIDS are presented as equivalent odds ratios (eORs). We identified eight original meta-analyses, including 152 original articles, covering 12 unique risk and protective factors for SIDS across 21 countries/regions and five continents. Several risk factors, including prenatal drug exposure [eOR = 7.84 (95% CI = 4.81-12.79), CE = highly suggestive], prenatal opioid exposure [9.55 (95% CI = 4.87-18.72), CE = suggestive], prenatal methadone exposure [9.52 (95% CI = 3.34-27.10), CE = weak], prenatal cocaine exposure [4.38 (95% CI = 1.95-9.86), CE = weak], prenatal maternal smoking [2.25 (95% CI = 1.95-2.60), CE = highly suggestive], postnatal maternal smoking [1.97 (95% CI = 1.75-2.22), CE = weak], bed sharing [2.89 (95% CI = 1.81-4.60), CE = weak], and infants found with heads covered by bedclothes after last sleep [11.01 (95% CI = 5.40-22.45), CE = suggestive], were identified. On the other hand, three protective factors, namely, breastfeeding [0.57 (95% CI = 0.39-0.83), CE = non-significant], supine sleeping position [0.48 (95% CI = 0.37-0.63), CE = suggestive], and pacifier use [0.44 (95% CI = 0.30-0.65), CE = weak], were also identified. Based on the evidence, we propose several risk and protective factors for SIDS. This study suggests the need for further studies on SIDS-related factors supported by weak credibility, no association, or a lack of adequate research.

Correlation of gestational age and age at death in sudden infant death syndrome: another pointer to the role of critical developmental period?

Filiano and Kinney proposed a triple-risk model for the sudden infant death syndrome (SIDS) that involves the intersection of three risks: (1) a vulnerable infant, (2) a critical developmental period in homeostatic control, and (3) an exogenous stressor(s). The primary evidence for the role of a critical developmental period in SIDS etiology is the peak of cases around the third month of life. Independently, several studies pointed to correlation between gestational age and age at death in SIDS, but used that to assess the SIDS risk for preterm infants, ignoring further ramifications. We did a detailed analysis of CDC data spanning over two decades (1983-2011). We focused not only on the correlation between two age variables (gestational and age at death), but also on the possibility of misdiagnosis. Also, we attempted to account for potential biases in the data induced by the ICD-9/ICD-190 transition or the "Back to Sleep" campaign. The peak of deaths in the third month of life, that was the main argument for the role of the critical development period, wasn't unique to SIDS. However, we confirmed an almost linear and negative correlation between gestational age and the week of death due to SIDS. This pattern (slope of correlation < 0 and significance of correlation p < 0.05) is characteristic of SIDS among all diseases analyzed in the study. We interpret the results as the evidence of the role of the critical development period in SIDS etiology. Possibly more attention in the future research should be put to theories that are based on homeostatic control.

Progress towards universal health coverage and inequalities in infant mortality: an analysis of 4·1 million births from 60 low-income and middle-income countries between 2000 and 2019

Expanding universal health coverage (UHC) might not be inherently beneficial to poorer populations without the explicit targeting and prioritising of low-income populations. This study examines whether the expansion of UHC between 2000 and 2019 is associated with reduced socioeconomic inequalities in infant mortality in low-income and middle-income countries (LMICs). We did a retrospective analysis of birth data compiled from Demographic and Health Surveys (DHSs). We analysed all births between 2000 and 2019 from all DHSs available for this period. The primary outcome was infant mortality, defined as death within 1 year of birth. Logistic regression models with country and year fixed effects assessed associations between country-level progress to UHC (using WHO's UHC service coverage index) and infant mortality (overall and by wealth quintile), adjusting for infant-level, mother-level, and country-level variables. A total of 4 065 868 births to 1 833 011 mothers were analysed from 177 DHSs covering 60 LMICs between 2000 and 2019. A one unit increase in the UHC index was associated with a 1·2% reduction in the risk of infant death (AOR 0·988, 95% CI 0·981-0·995; absolute measure of association, 0·57 deaths per 1000 livebirths). An estimated 15·5 million infant deaths were averted between 2000 and 2019 because of increases in UHC. However, richer wealth quintiles had larger associated reductions in infant mortality from UHC (quintile 5 AOR 0·983, 95% CI 0·973-0·993) than poorer quintiles (quintile 1 0·991, 0·985-0·998). In the early stages of UHC, UHC expansion was generally beneficial to poorer populations (ie, larger reductions in infant mortality for poorer households [infant deaths per 1000 per one unit increase in UHC coverage: quintile 1 0·84 vs quintile 5 0·59]), but became less so as overall coverage increased (quintile 1 0·64 vs quintile 5 0·57). Since UHC expansion in LMICs appears to become less beneficial to poorer populations as coverage increases, UHC policies should be explicitly designed to ensure lower income groups continue to benefit as coverage expands.

Features of &lt;i&gt;ESCHERICHIA COLI&lt;/i&gt; samples from patients with diarrheal syndrome in the Republic of Guinea

Introduction. Diarrheal diseases are a global public health issue and cause 15% of deaths in children under 5 years old, of which about 80% occur in the regions of Africa and Southeast Asia. According to the Global Enteric Multicentre Study (GEMS) conducted in a number of African countries, one of the leading pathogens of high risk of death in infants and young children is diarrheagenic E. coli (DEC). In recent decades, antimicrobial resistance (AMR) has become globally ubiquitous. The Republic of Guinea urgently needs large-scale studies devoted to assessing DEC distribution and antibiotic resistance. The purpose of the study is to assess the pattern of E. coli infections and to test the susceptibility to antibiotics in strains of diarrheagenic E. coli sampled from individuals residing in the Republic of Guinea.&#x0D; Materials and methods. From 2019 to 2022, we studied 724 samples of faeces of patients with acute diarrhea, among them 72 (9.9%) children aged 1–5 years, 128 (17.7%) children aged 6–17 years, and 524 (72.4%) people aged 18 years and older; a method of polymerase chain reaction (PCR) was applied with the use of the AmpliSense® Escherichioses-FL reagent kit to identify the genetic determinants of DEC: EPEC, EHEC, ETEC, EIEC, and EAgEC (Central Research Institute of Epidemiology of Rospotrebnadzor, Russia). Susceptibility to 15 antimicrobial agents was found by the disc-diffusion method using Mueller–Hinton agar (Russia) and Oxoid discs (UK). Results were interpreted according EUCAST criteria, versions 2019–2022 (https://www.eucast.org/ast_of_bacteria/previous_versions_of_documents).&#x0D; Results. For the period from 2019 to 2022, the percentage of E. coli infections in the etiological pattern of acute intestinal infections amounted to 51.7%. In the age-related manner, DEC was significantly more common in young children aged 0–5 (96.9%, p 0.05) as compared to school age children aged 6–17 (53.9%) and adults (45.6%). In all years of observation, EAgEC strains prevailed, accounting for 38.4%. Other DEC pathotypes, EPEC, ETEC, EIEC and STEC, accounted for 27.2%, 17.5%, 11.8%, and 5.1%, respectively. DEC strains are susceptible to meropenem, amikacin, and nitrofurantoin. The activity of other antibiotics ranged from 11.3% for ampicillin, 28.3% for trimethoprim-sulfamethoxazole, and 34.0% for tetracycline to 73.6% for cephalosporins, 84.0% for aminoglycosides, and 98.1% for fluorinated quinolones.&#x0D; Conclusion. To reduce the burden of diarrheal diseases in the Republic of Guinea, it may be necessary to conduct targeted epidemiological and microbiological studies to identify DEC and monitor the development of antimicrobial resistance of E. coli infection pathogens in the population.

The study of the microbiome in forensic investigations on pediatric deaths.

Sudden infant death syndrome (SIDS) is a tragic and devastating condition whose causes remain largely unknown. Recent studies have shown that the composition of a child's gut flora can play a significant role in the development of SIDS. This work aims to research those factors that influence the composition of the intestinal flora, the role they have in the development of SIDS and the new strategies for preventing SIDS showing a new interpretation through a detailed review of the literature. The gut in physiological conditions is mainly composed of Bacteroidetes, Firmicutes, Actinobacteria, and Proteobacteria, but when there is the presence of dysbiotic or different microbial communities, the onset of the disease is more likely as an altered microbial community can lead to an interruption of the gut-brain axis and an increased risk of SIDS. All this implies that the composition of the microbiome can be modified to reduce the risk of sudden death in newborns. The results of the literature provide valuable information on the potential role of the intestinal microbiome in SIDS even if not all mechanisms are yet clear, especially in the mechanisms of death. Therefore, it is necessary in cases of SIDS when carrying out an autopsy to also investigate this area; to this end, we suggest a questionnaire to be administered to family members to understand the eating habits of the newborn and the family and integrate with microbiological investigations to explore every possible hypothesis.

Evaluation of mothers' knowledge about infant sudden death syndrome and its risk factors.

Sudden infant death syndrome is the third leading cause of infant death in the first year of life and is one of the most important health problems around the world. The exact etiology of this phenomenon is not clear yet, but some risk factors, especially prone sleep positions, have been described. Fortunately, by modifying some environmental factors, the SIDS incidence might be decreased. Mothers' and caregivers' knowledge about this neglected event could be an important factor in determining SIDS prevalence. This cross-sectional study was conducted in the pediatric and neonatal specialty clinic of Bahar Shahroud Hospital in 2020. Five hundred and twenty-seven pregnant women of reproductive age (18 to 45 years) were included in the study. Assessment of mothers' knowledge was done using a sudden infant death syndrome risk questionnaire. Statistical analysis of data was performed using independent t-test, Chi-square, and logistic regression. The number of 527 pregnant women of childbearing age participated in our study. 81.9% were under 35 years old. According to the study, factors such as maternal age, mother's level of education, number of pregnancies, and history of previous infant death syndrome had a significant relationship with the mother's level of knowledge about infant death syndrome. The findings showed that the mother's age is over 35 years old during pregnancy (CI: 0.95-0.46-OR: 1.53) and the level of education under a diploma (CI: 3.13-1.6: 06, OR: 1.86), and increasing parity is associated with a lower level of knowledge about infant death syndrome. According to mothers' lack of knowledge about SIDS and the availability of simple and cost-effective methods to prevent SIDS, improving mothers' knowledge about this important event in pregnancy and postpartum, educational sessions are crucial.

National SIDS Trends in the United States From 2000 to 2019: A Population-Based Study on 80 Million Live Births

Sudden infant death syndrome (SIDS) is the most common cause of death for infants between 1 month and 1 year of age in the United States. The objective was to examine recent trends in SIDS in the United States, over time and by sex and race. A population-based cross-sectional study was conducted on 80 710 348 live births using data from the Center for Disease Control and Prevention’s (CDC) “Birth Data” and “Mortality Multiple Cause” files from 2000 to 2019. Logistic regression examined the effects of sex and race on the risk of SIDS and examined temporal changes in risk across sex and race over the study period. Incidence of SIDS decreased from 6.3 to 3.4/10 000 births from 2000 to 2019, with an overall incidence of 4.9/10 000 births (95% confidence interval [CI] = 4.4-5.3). Male infants were at the greatest risk of SIDS as were black and American Indian infants. Although SIDS incidence decreased by sex and race over time, the decline was smaller among Hispanic and American Indian infants.

Choline-acetyltransferase (ChAT) and acetylcholinesterase (AChE) in the human infant dorsal motor nucleus of the Vagus (DMNV), and alterations according to sudden infant death syndrome (SIDS) category

Amongst other molecules, the cholinergic system consists of choline-acetyltransferase (ChAT, − synthesis enzyme), acetylcholinesterase (AChE – primary hydrolysis enzyme), and butyrylcholinesterase (BuChE – secondary hydrolysis enzyme). In the brainstem, the Dorsal Motor Nucleus of The Vagus (DMNV) has high cholinergic expression and is a region of interest in the neuropathology of sudden infant death syndrome (SIDS). SIDS is the unexpected death of a seemingly healthy infant, but postmortem brainstem abnormalities suggesting altered cholinergic regulation have been found.This study aimed to determine the percentage of positive ChAT and AChE neurons within the infant DMNV through immunohistochemistry at the three levels of the brainstem medulla (caudal, intermediate, and rostral), to investigate whether the proportion of neurons positive for these enzymes differs amongst the diagnostic subgroups of SIDS compared to those with an explained cause of Sudden unexpected death in infancy (eSUDI), and whether there were any associations with SIDS risk factors (male gender, cigarette smoke exposure, co-sleeping/bed sharing, and prone sleeping). Results showed that ChAT-positive neurons were lower in the rostral DMNV in the SIDS II cohort, and within the caudal and intermediate DMNV of infants who were exposed to cigarette smoke. These findings suggest altered cholinergic regulation in the brainstem of SIDS infants, with potential contribution of cigarette smoke exposure, presumably via the nicotinic acetylcholinergic receptor system.

PENGARUH WOOLWICH MASSAGE TERHADAP KELANCARAN PENGELUARAN ASI IBU POSTPARTUM DI RUMAH SAKIT WILAYAH KABUPATEN WONOSOBO

Breast milk is milk that contains all the nutrients a baby needs to grow and develop. WHO says that exclusive breastfeeding is very beneficial for mothers and babies, the most important thing is to protect babies from gastrointestinal infections so that the risk of infant death due to diarrhea and other infections. One of the efforts that can be made to increase lactation hormones is to do breast care. Stimulating oxytocin and prolactin in postpartum mothers is by creating a feeling of relaxation, one of which is by doing woolwich massage. Researchaims to determine whether or not there is an effect of woolwich massage on the smooth production of breast milk in portpartum mothers in hospitals in Kab. Wonosobo.

The population is the average postpartum vaginal mothers from January to May 2023 at RSI Wonosobo and RSUD KRT. Setjonegoro Wonosobo. The sampling techniques used were quota sampling and bivariate analysis with the Mann Whitney U test. The results showed there was a difference between the experimental group and the control group with a p-value of 0.013&lt;α (0.05). Conclusion: asignificant effect of wooolwich massage on the smooth milk production of postpartum mothers.&#x0D; &#x0D;

Screening and Prevention of Preterm Birth in Twin Pregnancies.

Twins represent 3.2% of all live births. However, they account for 20% of all preterm deliveries, 60% delivering <37 weeks, 10.7% <32 weeks, and 5 times higher risk of infant death. Risk factors for preterm birth (PTB) include the history of preterm delivery, monochorionic twins, short cervical length, and cervical surgery. Transvaginal cervical length <24 weeks is the best tool to predict PTB. Only vaginal progesterone in women with transvaginal cervical length <25mm and physical exam indicated cerclage in women with cervical dilation >1cm have shown a significant decrease in PTB and improvement in neonatal outcomes.

Impact of Bowel Coverage and Resuscitation Protocol on Gastroschisis Mortality in Low-Income Countries: Experience and Lessons From Uganda

BackgroundGastroschisis causes near complete mortality in low-income countries (LICs). This study seeks to understand the impact of bedside bowel reduction and silo placement, and protocolized resuscitation on gastroschisis outcomes in LICs. MethodsWe conducted a retrospective cohort study of gastroschisis patients at a tertiary referral center in Kampala, Uganda. Multiple approaches for bedside application of bowel coverage devices and delayed closure were used: sutured urine bags (2017–2018), improvised silos using wound protectors (2020–2021), and spring-loaded silos (2022). Total parental nutrition (TPN) was not available; however, with the use of improvised silos, a protocol was implemented to include protocolized resuscitation and early enteral feeding. Risk ratios (RR) for mortality were calculated in comparison to historic controls from 2014. Results368 patients were included: 42 historic controls, 7 primary closures, 81 sutured urine bags, 133 improvised silos and 105 spring-loaded silos. No differences were found in sex (p = 0.31), days to presentation (p = 0.84), and distance traveled to the tertiary hospital (p = 0.16). Following the introduction of bowel coverage methods, the proportion of infants that survived to discharge increased from 2% to 16–29%. In comparison to historic controls, the risk of mortality significantly decreased: sutured urine bags 0.65 (95%CI: 0.52–0.80), improvised silo 0.76 (0.66–0.87), and spring-loaded silo 0.65 (0.56–0.76). ConclusionBedside application of bowel coverage and protocolization decreases the risk of death for infants with gastroschisis, even in the absence of TPN. Further efforts to expand supply of low-cost silos in LICs would significantly decrease the mortality associated with gastroschisis in this setting. Type of StudyTreatment Study. Level of EvidenceIII (Retrospective Comparative Study).

Assessment of mothers' awareness of sudden infant death syndrome and safe infant sleep practices in Palestine

ObjectiveOne of the major public health mysteries around the world is a subcategory of infant sleep-related deaths of unknown etiology termed Sudden Infant Death Syndrome (SIDS) which is a common leading cause of infant mortality worldwide and targets infants under a year of age while sleeping. Sleep environment plays a significant role in the risk of SIDS, mothers actions for creating safe infant sleep practices play a protective role in reducing SIDS occurrence. The knowledge gap centered on SIDS is not adequately researched or investigated in Palestine. Correspondingly, the study aims to assess mothers' awareness of SIDS and safe infant sleep practices. MethodsA cross-sectional quantitative design was used. A self-reported questionnaire containing 30 items was distributed to childbearing mothers in various rural and urban areas in Palestine. The 1116 participants were selected based on a non-probability, convenience method in duration from April 1st, 2023 to June 19th, 2023. ResultThe data were analyzed through the SPSS program version 20; specifically, one-way ANOVA, independent sample T-tests, and Pearson's correlation test. The mother's total awareness and practice scores were coded into two categories: 1 signifying poor awareness or practice, and 2 signifying good awareness or practice. The mean total awareness was calculated to be 1.444, while the standard deviation came out to 0.497. The mean total practice was calculated to be 8.0789, while the standard deviation came out to 2.223. To further elaborate, 55.6% of the mothers showed poor awareness regarding SIDS. Moreover, 84.5% of the mothers revealed they had poor practices regarding safe infant sleep practices. ConclusionThe study displayed a positive-moderate correlation between the mothers' awareness and practices. Specifically, mothers’ had poor awareness in addition to poor practices.

Infant death prediction using machine learning: A population-based retrospective study

BackgroundDespite declines in infant death rates in recent decades in the United States, the national goal of reducing infant death has not been reached. This study aims to predict infant death using machine-learning approaches. MethodsA population-based retrospective study of live births in the United States between 2016 and 2021 was conducted. Thirty-three factors related to birth facility, prenatal care and pregnancy history, labor and delivery, and newborn characteristics were used to predict infant death. ResultsXGBoost demonstrated superior performance compared to the other four compared machine learning models. The original imbalanced dataset yielded better results than the balanced datasets created through oversampling procedures. The cross-validation of the XGBoost-based model consistently achieved high performance during both the pre-pandemic (2016–2019) and pandemic (2020–2021) periods. Specifically, the XGBoost-based model performed exceptionally well in predicting neonatal death (AUC: 0.98). The key predictors of infant death were identified as gestational age, birth weight, 5-min APGAR score, and prenatal visits. A simplified model based on these four predictors resulted in slightly inferior yet comparable performance to the all-predictor model (AUC: 0.91 vs. 0.93). Furthermore, the four-factor risk classification system effectively identified infant deaths in 2020 and 2021 for high-risk (88.7%–89.0%), medium-risk (4.6%–5.4%), and low-risk groups (0.1), outperforming the risk screening tool based on accumulated risk factors. ConclusionsXGBoost-based models excel in predicting infant death, providing valuable prognostic information for perinatal care education and counselling. The simplified four-predictor classification system could serve as a practical alternative for infant death risk prediction.

Awareness of sudden infant death syndrome and its associated risk factors among Saudi mothers attending well-baby clinics at PHC, PSMMC, Riyadh, Saudi Arabia: A cross-sectional study.

Sudden infant death syndrome (SIDS) is a leading cause of infant mortality all over the world. Mortality due to SIDS can be averted by educating families and caretakers about safe practices for putting infants to sleep. However, the knowledge, attitude, and practices of mothers while putting the infant to sleep is a gray areas in literature. The objectives of the study were to measure the knowledge and awareness about SIDS and its associated risk factors practiced among Saudi mothers attending well-baby clinics in Saudi Arabia to develop appropriate educational program-based interventions for safe practices of infant care. This cross-sectional study was carried out among 385 mothers attending well-baby clinics of primary health care (PHC) and prince sultan military medical city (PSMMC) in Riyadh Saudi Arabia. Information was captured on sociodemographic characteristics, the health status of mothers and infants, knowledge, attitude, and practice followed by mothers while putting infants to sleep. From a total number of 385 responses, 350 participants were eventually included in the final sample due to the incompletion of the questionnaire of 350 mothers; only 26% (n = 93) mothers had heard of SIDS. However, 259 mothers were willing to attend the awareness session. Only 94 mothers had knowledge as well as practicing the correct behavior of putting the infant to sleep on the back referred to as "good behavior concordant pairs." Similarly, other good practices include not co-sharing a bed with the infant, removing pillows, blankets, and other wedged objects, using a pacifier, breastfeeding the infant during sleep, not using multiple quilts, not covering the infant's head with a quilt, not using a head cap. The number of good behavior concordant pairs (in green) were 124, 38, 56, 98, 18, 117, and 68 respectively. The rate of knowledge and practice for good behavior regarding SIDS was low among Saudi mothers in Riyadh Saudi Arabia. SIDS-related deaths can be averted by improving the understanding of SIDS risk reduction practices among mothers by using health promotion strategies.

Development IoT-based Infant Monitoring System for Preventing Sudden Infant Death Syndrome (SIDS) with Abnormal Condition Notifications and Lost Data Analysis

Sudden Infant Death Syndrome (SIDS) is a devastating phenomenon where an otherwise healthy baby under the age of one inexplicably passes away without any apparent symptoms. It can be triggered by a variety of factors, including the baby's sleeping position and the infant's physiological state, which may not have reached a certain stage of development. Efficient monitoring of vital parameters such as body temperature and heart rate is crucial for assessing and safeguarding the baby's health.
