sudden unexpected infant death

PURPOSE: Genetic studies in sudden infant death syndrome (SIDS) and sudden unexplained death (SUD) cohorts have indicated that cardiovascular diseases might have contributed to sudden unexpected death in 20-35 % of autopsy-negative cases. Sudden unexpected death can also occur in people with epilepsy, termed as sudden unexpected death in epilepsy (SUDEP). The pathophysiological mechanisms of SUDEP are not well understood, but are likely multifactorial, including seizure-induced hypoventilation and arrhythmias as well as genetic risk factors...

In the past, histological diagnosis of (post-)viral myocarditis was based on the so-called Dallas criteria, which have been criticized because of high interobserver variability and sampling error. Immunohistochemical qualification and quantification of interstitial intramyocardial leucocytes was established and standard values concerning adults were published. Fatal casualties due to a viral myocarditis are rare as far as babies and children are concerned (sudden unexpected death in infancy; SUDI). Cases of sudden unexpected death in the first year of life are frequently regarded as sudden infant death syndrome (SIDS)...

BACKGROUND: Many infancy-onset epilepsies have poor prognosis for seizure control and neurodevelopmental outcome. Ketogenic diets can improve seizures in children older than 2 years and adults who are unresponsive to antiseizure medicines. We aimed to establish the efficacy of a classic ketogenic diet at reducing seizure frequency compared with further antiseizure medicine in infants with drug-resistant epilepsy. METHODS: In this phase 4, open-label, multicentre, randomised clinical trial, infants aged 1-24 months with drug-resistant epilepsy (defined as four or more seizures per week and two or more previous antiseizure medications) were recruited from 19 hospitals in the UK...

INTRODUCTION: Sudden unexpected infant death (SUID) is the leading cause of death among U.S. infants aged 28 days to 1 year. In Kansas, Hispanic infant mortality is nearly 50% higher than non-Hispanic White. Further, the SUID rate did not change between 2005-2018, while rates for non-Hispanic Black and White infants decreased significantly. This study sought to identify characteristics and behaviors of Hispanic birthing persons related to SUID. METHODS: Linked Kansas birth/death vital statistics data (2005-2018) identified Hispanic birthing persons with a singleton birth who experienced SUID...

INTRODUCTION: Approximately 3400 infants die suddenly and unexpectedly each year in the United States; many of these deaths include modifiable risk factors (such as a non-supine position, sleeping on a soft surface, or loose bedding or items in the environment). Interventions have been successful at improving parental knowledge about recommendations to reduce risk of sleep-related infant deaths, as well as improving intention to adopt recommendations. However, follow-up studies have found a disconnect between knowledge/intentions to adhere to recommendations and actual practices...

Sleep-related infant deaths, now called sudden unexpected infant deaths, are not declining, and the United States continues to have greater rates than most other developed nations. Health disparities are significant, with death rates greater in certain vulnerable groups, including non-Hispanic Black infants. Nurses play a crucial role in educating, role-modeling, and problem-solving with parents. Thus, it is critical for nurses to stay current with the science, prevention recommendations, and societal decisions and debates surrounding this topic...

BACKGROUND: Our objectives were to compare safe sleep knowledge, attitudes and planned vs. actual infant sleep practices among expectant mothers before and after their infant's birth and to determine whether differences (if present) were associated with any demographic variables. METHODS: Study participants were surveyed at their 28-week prenatal and 6-week postpartum obstetric clinic visits from November 2019-February 2021. Due to COVID-19 pandemic cancellation of in-person postpartum visits, many participants received text messaging encouraging them to take the follow-up survey online...

Sudden unexpected infant death may be explained, cause by an etiology, unexplained but insufficiently investigated, or unexplained when a full investigation fails to determine the cause. Unexplained sudden death in infancy or sudden infant death syndrome particularly affects the most vulnerable populations. The death of these children who are born with alterations in their neurodevelopment is the visible part of a problem that originates in pregnancy. Reducing the number of vulnerable children depends on health policies and, above all, on improving the living conditions of the population...

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...

OBJECTIVE: To describe the level of inconsistency between pictures on baby diaper packaging and safe infant sleep recommendations (SISRs) in Europe. STUDY DESIGN: We attempted to identify all packaging of baby diapers sold in 11 European countries for infants weighing less than 5 kg through internet searches from July 2022 through February 2023. For each type of package, we extracted whether there was a picture depicting a baby, whether the baby was sleeping, and whether the picture of the sleeping baby was inconsistent with ≥1 of 3 SISRs: (i) non-supine sleeping position, (ii) soft objects or loose bedding, or (iii) sharing a sleep surface with another person...

BACKGROUND: Hyperthermia is a known risk for sudden unexpected infant death. The practice of hat placement at birth to prevent transient hypothermia may not be necessary and sets an early standard for clothing infants that may lead to hyperthermia postnatally. OBJECTIVE: To examine the elimination of hats on thermoregulation (eg, hypothermia, <97.6°F) in full-term newborns with no abnormalities within 24 hours of birth. METHODS: In 2018, an institution guideline discontinued the use of hats at birth...

INTRODUCTION: To study the clinical presentation, laboratory profile, echocardiographic details, management, and outcomes of children who were diagnosed to have multisystem inflammatory syndrome in children (MIS-C) in the immediate postoperative period after surgery for congenital heart defects (CHDs). MATERIALS AND METHODS: This is a prospective case-control study that included children diagnosed to have MIS-C in the postoperative period based on clinical signs, rise in inflammatory markers, and echocardiographic features of ventricular dysfunction or coronary involvement...

(1) Background: The study's purpose was to explore the knowledge, perceptions, and confidence of mothers about infant care to reduce the risk of sudden unexpected infant death. (2) Methods: A purposeful sampling method was used to recruit 15 first-time mothers from Georgia with infants under 1 year of age. The researchers utilized the Socio-ecological model to report the results. Participants also provided recommendations on how to improve infant care and reduce the risk of SUID. (3) Results: The confidence level of infant care among most participants was low but increased over time...

PURPOSE: In this study we performed WGS of children that succumbed to SUID during their first year of life to gain insights into potential genetic risk factors that could contribute to an infant's vulnerability to this tragic outcome. METHODS: Whole genome sequencing was performed on 145 SUID cases, and 576 healthy adult controls. Variants were filtered by gnomAD allele frequencies and predictions of functional consequences using computational tools. RESULTS: In 63...

OBJECTIVES: Safe sleep of infants is important to reduce the risk of Sudden Unexpected Death in Infancy (SUDI). The depiction of infant care behavior which is inconsistent with the safe sleep recommendations on social media has an impact on parental infant care thoughts, norms and behaviors. This study aims to determine the adherence of Instagram images to the Dutch safe sleeping advice. DESIGN: A systematic social media analysis on Instagram was performed using 22 hashtags and 9 accounts of Dutch companies or platforms related to infants...

OBJECTIVES: Child abuse should be considered in cases of sudden unexpected infant death (SUID). Postmortem skeletal surveys (PM-SS) are recommended to evaluate for abusive fractures in SUID. Little is known about the yield of PM-SS among infants presenting to emergency care with SUID. Our objectives were to (1) describe the presentation and care of infants with SUID at a tertiary children's hospital emergency department and (2) report PM-SS use and findings. METHODS: We performed a retrospective study of infants younger than 12 months with SUID presenting to an urban emergency department from 2007 to 2019...

Sudden unexpected death in infants (SUDI) is a traumatic event for families, and unfortunately its occurrence remains high in many parts of the world. Whilst cause of death is resolved for most cases, others remain undetermined following postmortem investigations. There has been a recognition of the role of genetic testing in unexplained cases, where previous studies have demonstrated the resolution of cases through DNA analyses. Here we present two case reports of SUDI cases admitted to Salt River Mortuary, South Africa, and show that underlying causes of death were determined for both infants using clinical exome sequencing...

BACKGROUND: Sudden unexpected death in infancy (SUDI) is the most common cause of post-neonatal death in the developed world. Following an extensive investigation, the cause of ~40% of deaths remains unknown. It is hypothesized that a proportion of deaths are due to an infection that remains undetected due to limitations in routine techniques. This study aimed to apply 16S rRNA gene sequencing to post-mortem (PM) tissues collected from cases of SUDI, as well as those from the childhood equivalent (collectively known as sudden unexpected death in infancy and childhood or SUDIC), to investigate whether this molecular approach could help identify potential infection-causing bacteria to enhance the diagnosis of infection...

A definitive, authoritative approach to evaluate the causes of unexpected, and ultimately unexplained, pediatric deaths remains elusive, relegating final conclusions to diagnoses of exclusion in the vast majority of cases. Research into unexplained pediatric deaths has focused primarily on sudden infant deaths (under 1 year of age) and led to the identification of several potential, albeit incompletely understood, contributory factors: nonspecific pathology findings, associations with sleep position and environment that may not be uniformly relevant, and the elucidation of a role for serotonin that is practically difficult to estimate in any individual case...

BACKGROUND: Sudden Unexpected Infant Death (SUID) is the leading cause of death in infants 1 month to 1 year of age in the United States. Despite extensive efforts in research and public education, rates of sleep-related infant death have plateaued since the late-1990s, largely due to unsafe sleep practices and environments. LOCAL PROBLEM: A multidisciplinary team assessed our institution's compliance with its own infant safe sleep policy. Data was collected on infant sleep practices, nurses' knowledge and training on the hospital policy, and teaching practices for parents and caregivers of hospitalized infants...
