Recent Iowa Trends in Sudden Unexpected Infant Deaths: The Importance of Public Health Collaboration With Medical Examiners’ Offices

A systematic review exploring the relationship between infection and sudden unexpected death between 2000 and 2016: A forensic perspective

Death due to infectious diseases is a major health concern worldwide. This is of particular concern in developing countries where poor-socio economic status and a lack of healthcare resources contribute to the high burden of disease. In some cases death due to infection can be acute and aggressive, and death may occur without a diagnosis whilst the person is still alive. These deaths may ultimately lead to a medico-legal autopsy being performed. There are various mechanisms by which sudden death due to infection may occur. In addition, there are many risk factors associated with sudden death due to infection, which differ between infants and older individuals. However, it is unclear which pathogens and risk factors are most frequently associated with sudden death due to infection. Therefore a systematic review of articles and case reports published between 1 January 2000 and 30 June 2016 was undertaken in order to (1) explore the relationship between pathogens and their causative role and (2) identify the relationship between predisposing and/or risk factors associated with sudden death due to infection. Major databases were searched and after critical appraisal 143 articles were identified. It was found that respiratory infections and deaths involving bacterial pathogens were most commonly associated with these deaths. In addition the most common risk factors in infants were exposure to tobacco smoke and co-sleeping. In adults the most common risk factors were co-morbid conditions and illnesses. This information aids in a better understanding of these deaths and highlights the need for more research in this field, particularly in developing countries.

Sudden unexpected infant death in Jordan and the home environment

BACKGROUND

The aim of this study was to evaluate maternal common practice for infant sleep care and the home environment, in order to explore the major risk factors associated with sudden unexpected infant death in Jordan.

METHODS

Data were collected via semi-structured questionnaire interview to investigate the sociodemographic features, infant sleep practices and home environments. The sample included 604 mothers with infants <1 year old. Descriptive statistics were generated.

RESULTS

Sleep practices were identified as leading factors in unexpected infant death. They included infant head covering (84%), heavy bedding with multiple quilts (81%) or blankets (67%), and co-bedding (66%). Environmental risk factors included high incidence of smoking, exposure to toxic solid fuel heaters during winter and inadequate room ventilation.

CONCLUSION

Factors leading to unexpected infant death were high in Jordan. Unsafe infant sleeping practices and poor environmental factors put infants at high risk of sudden death. Lack of awareness of risk factors increases the risk.

Social and behavioural factors in Non-suspicious unexpected death in infancy; experience from metropolitan police project indigo investigation

Background

Risk factors for Sudden Unexpected Death in Infancy (SUDI) are well described, and such cases are now investigated according to standard protocols. In London, Project Indigo of the Metropolitan Police provides a unique, detailed framework for such data collection. We investigate such data to provide a contemporary account of SUDI in a large city and further link data to publically available datasets to investigate interactions with social factors.

Methods

Retrospective analysis of data routinely collected by the Metropolitan Police Service in all cases of non-suspicious SUDI deaths in London during a six year period.

Results

SUDI deaths are associated with markers of social deprivation in London. A significant proportion of such deaths are associated with potentially modifiable risk factors such as cigarette smoking and co-sleeping, such behaviour also being associated with social factors, including accommodation issues.

Conclusions

Routinely collected data provide valuable insight into patterns and associations of mortality, with SUDI remaining a significant issue in London. Risk factors include social disadvantage, which may manifest in part by affecting behavioural patterns such as co-sleeping and public health interventions to reduce rates require significant social modification.
