Prevalence and characteristics of online child sexual victimization: Findings from the Australian Child Maltreatment Study.

Background: Online child sexual victimization is increasingly facilitated by technology, but evidence of its prevalence and characteristics remains scarce. Reliable population-based data is critical to understand the magnitude and nature of the problem, and inform evidence-based prevention.

Objective: To determine the prevalence of nonconsensual sharing of sexual images of the child by any perpetrator, and of online sexual solicitation by any adult perpetrator; and to determine the characteristics of these experiences.

Disclosure and non-disclosure of childhood sexual abuse in Australia: Results from a national survey.

Background: Little population-based evidence exists about prevalence of lifetime disclosure and non-disclosure of child sexual abuse (CSA). Evidence is lacking about disclosure by girls and women compared with boys and men, and gender diverse individuals. It is unclear if disclosure is more common in contemporary society, and if disclosure is influenced by abuse severity and perpetrator type.

Dimensions of Child Maltreatment in Australians With a History of Out-of-Home Care.

Research suggests that the dimensions of childhood maltreatment (type, age of onset, duration, frequency and perpetrator) play an important role in determining health and wellbeing outcomes, though little information is available on these dimensions for any care experienced cohorts. This study aimed to determine if any variation in maltreatment dimensions were experienced between two subsets of the nationally representative Australian Child Maltreatment Study, both of which reported childhood maltreatment histories: care-experienced ( = 358) and non-care-experienced ( = 4922). Using a series of independent t-tests and chi-square tests, we compared the two groups on seven dimensions (number of maltreatment types, range of maltreatment items, age of onset, duration, frequency, perpetrator number, and perpetrator type) for the five child maltreatment types (physical, emotional, sexual abuse, neglect, and exposure to domestic violence).

Diagnostic Accuracy of Contrast-Enhanced MRI for Detection of Perineural Spread in Head and Neck Cancer: A Systematic Review and Meta-Analysis.

 The aim of this study was to determine the diagnostic accuracy of contrast-enhanced magnetic resonance imaging (CE-MRI) for the detection of perineural spread (PNS) in head and neck cancer patients.  A systematic review of PubMed, Embase, Scopus, Web of Science and Cochrane Library databases was performed up to May 20, 2022. We included diagnostic accuracy studies that used CE-MRI for the diagnosis of PNS in patients with head and neck cancer, using histopathology from surgical specimens as the reference standard.
