Northern Ireland Infant Death Thematic Review 2015

Co-Sleeping and bed sharing are considered the social norm for approximately 90% of the world's population, with two-thirds of the world's cultures habitually practicing mother-infant co-sleeping on the same bed. Although international studies show that the practice of co-sleeping is common, it is controversial in the public health community, as many consider it a significant risk for Sudden Infant Death Syndrome (SIDS), accounting for 50% of SIDS deaths in the UK. The report offers an international review of the evidence and provides important debates and critical knowledge for both health professionals, parents and all those organisations working to support the safety of infants in their first perinatal year.

Demographic and temporal trends in out of hospital sudden cardiac death in belfast

Objective: To determine the epidemiology of out of hospital sudden cardiac death (OHSCD) in Belfast from 1 August 2003 to 31 July 2004.

Design: Prospective examination of out of hospital cardiac arrests by using the Utstein style and necropsy reports. World Health Organization criteria were applied to determine the number of sudden cardiac deaths.

Results: Of 300 OHSCDs, 197 (66%) in men, mean age (SD) 68 (14) years, 234 (78%) occurred at home. The emergency medical services (EMS) attended 279 (93%). Rhythm on EMS arrival was ventricular fibrillation (VF) in 75 (27%). The call to response interval (CRI) was mean (SD) 8 (3) minutes. Among patients attended by the EMS, 9.7% were resuscitated and 7.2% survived to leave hospital alive. The CRI for survivors was mean (SD) 5 (2) minutes and for non-survivors, 8 (3) minutes (p < 0.001). Ninety one (30%) OHSCDs were witnessed; of these 91 patients 48 (53%) had VF on EMS arrival. The survival rate for witnessed VF arrests was 20 of 48 (41.7%): all 20 survivors had VF as the presenting rhythm and CRI ? 7 minutes. The European age standardised incidence for OHSCD was 122/100 000 (95% confidence interval 111 to 133) for men and 41/100 000 (95% confidence interval 36 to 46) for women.

Conclusion: Despite a 37% reduction in heart attack mortality in Ireland over the past 20 years, the incidence of OHSCD in Belfast has not fallen. In this study, 78% of OHSCDs occurred at home.

Heart Rhythm UK position statement on clinical indications for implantable cardioverter defibrillators in adult patients with familial sudden cardiac death syndromes

Whilst the decision regarding defibrillator implantation in a patient with a familial sudden cardiac death syndrome is likely to be most significant for any particular individual, the clinical decision-making process itself is complex and requires interpretation and extrapolation of information from a number of different sources. This document provides recommendations for adult patients with the congenital Long QT syndromes, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, hypertrophic cardiomyopathy, and arrhythmogenic right ventricular cardiomyopathy. Although these specific conditions differ in terms of clinical features and prognosis, it is possible and logical to take an approach to determining a threshold for implantable cardioveter-defibrillator implantation that is common to all of the familial sudden cardiac death syndromes based on estimates of absolute risk of sudden death.

Children’s Burial Grounds in Ireland (Cilliní) and Parental Emotions Toward Infant Death

Cilliní—or children’s burial grounds—were the designated resting places for unbaptized infants and other members of Irish society who were considered unsuitable by the Roman Catholic Church for burial in consecrated ground. The sites appear to have proliferated from the seventeenth century onwards in the wake of the Counter-Reformation. While a number of previous studies have attempted to relate their apparently marginal characteristics to the liminality of Limbo, evidence drawn from the archaeological record and oral history accounts suggests that it was only the Roman Catholic Church that considered cilliní, and those interred within, to be marginal. In contrast, the evidence suggests that the families of the dead regarded the cemeteries as important places of burial and treated them in a similar manner to consecrated burial grounds.

The effects of sudden paternal death on young people and their family relationships: some implications for practice

The importance for children and young people to be able to communicate openly about the death of a parent is evident from the literature. This small-scale investigation uses a case-study approach to illustrate the impact on siblings of the sudden death of a father. The abundance of comments from the young people in the study such as “talking is the only thing that helps” and “everybody has to get it out” emphasise the important role of communication within the family. Children tend to take their emotional cues from other family members and, paradoxically, restrict communication of their own grief in an attempt to protect others. Even if painful in the short term, certain lines of communication may need to be established if family members are to be able to support each other in dealing with the distressing experience of the death in a healthy manner. The study suggests that those who work with young people in such circumstances should take cognisance of these issues.

SIDS:the role of the family doctor

In the United Kingdom two thirds of deaths resulting from Sudden Infant Death Syndrome (SIDS) are confirmed at home and one third in hospital. The practising physician is likely to be confronted with a case every two to three years.

Progress and the Lack of Progress in Addressing Infant Health and Infant Health Inequalities in Ireland during the 20th Century

There is a growing literature which documents the importance of early life environment for outcomes across the life cycle. Research, including studies based on Irish data, demonstrates that those who experience better childhood conditions go on to be wealthier and healthier adults. Therefore, inequalities at birth and in childhood shape inequality in wellbeing in later life, and the historical evolution of the mortality and morbidity of children born in Ireland is important for understanding the current status of the Irish population. In this paper, I describe these patterns by reviewing the existing literature on infant health in Ireland over the course of the 20th century. Up to the 1950s, infant mortality in Ireland (both North and South) was substantially higher than in other developed countries, with a large penalty for those born in urban areas. The subsequent reduction in this penalty, and the sustained decline in infant death rates, occurred later than would be expected from the experience in other contexts. Using records from the Rotunda Lying-in Hospital in Dublin, I discuss sources of disparities in stillbirth in the early 1900s. Despite impressive improvements in death rates since that time, a comparison with those born at the end of the century reveals that Irish children continue to be born unequal. Evidence from studies which track people across the life course, for example research on the returns to birthweight, suggests that the economic cost of this early life inequality is substantial.

Cause-specific mortality adjudication in the UPLIFT® COPD trial:findings and recommendations

Mortality is an important endpoint in chronic obstructive pulmonary disease (COPD) trials, although accurately determining cause of death is difficult. In the Understanding the Potential Long-term Impacts on Function with Tiotropium (UPLIFT®) trial, a mortality adjudication committee (MAC) provided systematic, independent and blinded assessment of cause-specific mortality of all 981 reported deaths. Here we describe this process of mortality adjudication and methodological revisions introduced to help standardise the adjudication of two areas recognised to pose particular difficulty; firstly, the classification of fatal COPD exacerbations that occur in the setting of pneumonia and secondly, the categorisation of sudden death. In addition MAC determined cause of death was compared with that reported by site investigators (SIs). MAC-assigned causes of death were: respiratory, 35%; cancer, 25%; cardiovascular, 11%; sudden cardiac death, 4.4%; sudden death, 3.4%; other, 8.8%; unknown, 12.4%. Cancer/cardiac deaths were more common in Global Initiative for Chronic Obstructive Lung Disease stage II, respiratory deaths in stages III and IV. Agreement between MAC and SI regarding cause of death was complete (50.2%), incomplete (18.5%) or none (31.3%). The SI classified deaths as cardiac three-fold more frequently than MAC (incidence rate [IR]/100 patient-years 0.797 vs. 0.257), although IR ratios for cardiac deaths for tiotropium vs. control were similar between SI and MAC. Discrepancies between MAC- and SI-adjudicated causes of death are common, especially increased reporting of cardiac deaths by the SI. Future multicentre COPD trials should plan appropriate infrastructure before study initiation to ensure collection and interpretation of fatal events data.

Still Unequal at Birth: Birth Weight, Socioeconomic Status and Outcomes at Age 9

The prevalence of low birth weight is an important aspect of public health which has been linked to increased risk of infant death, increased cost of care, and a range of later life outcomes. Using data from a new Irish cohort study, I document the relationship between birth weight and socio-economic status. The association of maternal education with birth weight does not appear to be due to the timing of birth or complications during pregnancy, even controlling for a wide range of background characteristics. However, results do suggest intergenerational persistence in the transmission of poor early life conditions. Birth weight predicts a number of outcomes at age 9, including test scores, hospital stays and health. An advantage of the data is that I am able to control for a number of typically unmeasured variables. I determine whether parental investments (as measured by the quality of interaction with the child, parenting style, or school quality) mediate the association between birth weight and later indicators. For test scores, there is evidence of non-linearity, and boys are more adversely affected than girls. I also consider whether there are heterogeneous effects by ability using quantile regression. These results are consistent with a literature which finds that there is a causal relationship between early life conditions and later outcomes.

Sudden death and sudden birth of entanglement in common structured reservoirs

We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that for certain classes of entangled states, entanglement sudden death occurs, while for certain initially factorized states, entanglement sudden birth takes place. The backaction of the non-Markovian reservoir is responsible for revivals of entanglement after sudden death has occurred, and also for periods of disentanglement following entanglement sudden birth.

The significance of bruising in the pre-mobile infant

The majority of children in our society are loved andcherished. The occasional cases of intentional injury to a childresulting in death or significant harm evoke powerful anduncomfortable feelings (Devaney et al, 2013), and the publicoutcry may result in health and social workers facing criticism.Identifying whether an infant is at risk of abuse is a challengefor practitioners, and can be a source of stress and anxiety(Brandon et al, 2011). Bruising is a strong indicator of childabuse involving intentional injury (Kemp et al, 2014). Theincidence of bruising correlates to developmental stage, withnon-mobile infants least likely to incur bruising. Therefore, itspresence in pre-mobile infants requires immediate assessment.A search of the literature around bruising in pre-mobile infantsrevealed themes of missed opportunities for early intervention,the role of the father in the family and the significance of childdevelopment. Sharing of knowledge and expertise within themultidisciplinary team is key to safeguarding infants.
