Experiences and perspectives of women who have committed neonaticide, infanticide and filicide: A systematic review and qualitative evidence synthesis.

WHAT IS KNOWN ON THE SUBJECT?: The phenomenon of child killing (neonaticide, infanticide or filicide) is a rare event that cannot be fully explained by a single construct as each case involves the unique life circumstances of each woman who committed the act(s). WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The majority of women who committed neonaticide, infanticide or filicide regretted the act and regretted not seeking help from family and healthcare professionals. Women who committed neonaticide, infanticide or filicide in the main had complex circumstances characterised by poverty, abusive relationships, poor family and social support or over reliance on family supports and mental health issues. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Women require a clear plan of what to do if they feel overwhelmed with caring for a baby or child. Healthcare professionals involved with women in the perinatal period need to explore further women's expressions of "not being ready to be a mother" which for some women may be pathological and require further assessment. Women need to be made aware of the support service pathways available to them during the perinatal period and beyond. Further research is needed to explore and learn from women's experiences to reduce child homicide mortality and support women and their families. ABSTRACT: INTRODUCTION: Meaning and personal experiences of the acts of neonaticide, infanticide and filicide have rarely been investigated from the perspectives of the women who committed those acts. AIMS: To identify and synthesise evidence on the perspectives of women directly involved in the complex phenomena of neonaticide, infanticide or filicide from the evidence available on their unique point of view and how these experiences have affected women's lives. To understand how the experiences and perceptions of women who engaged in child killing present similarities or differences according to the child's age at time of death. METHODS: Qualitative primary studies published in English were included if they explored the experiences of women who engaged in neonaticide, infanticide or filicide. Methodological quality was assessed using the qualitative Critical Appraisal Skills Programme (CASP) checklist. A thematic analysis framework guided the synthesis. RESULTS: Seven papers reporting on five studies met the inclusion criteria for the review. Three analytical themes were identified: Not ready to be a mother; Intentionality and premeditation in the context of trauma and mental health issues; Sorrow of regret. DISCUSSION: The majority of women who committed neonaticide, infanticide or filicide had complex psychological, social and personal circumstances and in the main regretted the act and regretted not seeking help from family and healthcare professionals. Healthcare professionals in contact with women during the perinatal period and beyond need to be aware of the profiles of vulnerable women and undertake holistic integrated assessments to identify the woman's personal context, changes in interpersonal relationships, social isolation or over reliance on family supports and changes in mental health status or new onset of mental health conditions. IMPLICATIONS FOR PRACTICE: Women require a clear plan of what to do if they feel overwhelmed with caring for a baby or child. Healthcare professionals involved with women in the perinatal period need to explore further women's expressions of "not being ready to be a mother" which for some women might be pathological and require further assessment. Women need to be made aware of the support services pathways available to them during the perinatal period and beyond. Further research is needed to explore and learn from women's experiences of each of the phenomena separately to reduce child homicide mortality and support women and their families.

The use of sub-ablative Er:YAG laser irradiation in prevention of dental caries during orthodontic treatment.

PURPOSE: This « in-vitro ¼ study had two specific aims: the first, to test using a universal testing machine whether sub-ablative Er:YAG laser irradiation prior to acid etching is effective in orthodontic bracket bonding and secondly using micro-hardness measurements and Scanning Electron Microscopy (SEM) observations to investigate the effectiveness of de-mineralization reduction in enamel treated with sub-ablative Er:YAG laser irradiation followed by fluoride varnish application. MATERIALS AND METHODS: One hundred and eighty bovine permanent maxillary incisors were selected for shear bond strength testing and microhardness measurements. Sub-ablative Er:YAG laser irradiation was set at a power density of 2.5 J/cm(2), a frequency of 7 Hz and air/water spray. Brackets were bonded with an auto-curing resin paste. The shear bond strength was measured comparing laser irradiated and non-irradiated enamel surface, followed by SEM observation of the bracket-resin-enamel interface. Microhardness measurements were made on enamel samples before treatment, after samples preparation, and after demineralization. RESULTS: While the adhesion of orthodontic brackets to bovine enamel after sub-ablative Er:YAG laser irradiation and acid etching is comparable to that obtained after conventional acid etching, the effect of laser irradiation associated with topical application of fluoride varnish increases the microhardness of enamel. CONCLUSION: Sub-ablative Er:YAG laser irradiation before the acid etching doesn't reduce the shear bond whereas when associated with fluoride application it may play a role in caries prevention. Further studies will be necessary to establish the mechanism by which the protective laser activated fluoride effect is achieved.
