Novel pre-copulatory behavior in basking sharks observed by drone.

Basking sharks (Cetorhinus maximus) seasonally aggregate in coastal surface waters of the North Atlantic, providing opportunities for visual observation. While putative courtship displays have been observed, actual copulation has not been documented. Here we examine video collected by an unmanned aerial vehicle ("drone") of novel behavioral interactions between basking sharks in Cape Cod Bay, Massachusetts in May 2021.

Return to Activity After SARS-CoV-2 Infection: Cardiac Clearance for Children and Adolescents.

Context: Sedentary behavior and inability to participate in organized physical activity has negatively affected the physical and mental health of children and adolescents; however, cardiac injury and associated risk for sudden cardiac death with return to activity remains a major concern. Guidelines have been proposed for return to activities; however, these fail to address the needs of younger children and those participating in more casual activities. Guidance is needed for primary care providers to facilitate safe return to everyday activity and sports and to help direct appropriate laboratory, electrocardiographic, and anatomical assessment.

Iatrogenic medication errors reported to the Victorian Poisons Information Centre.

Background: Iatrogenic medication errors are a cause of medical morbidity and mortality. They result in significant cost to the Australian healthcare system each year. There is limited Australian evidence describing the iatrogenic errors occurring within the hospital system.

Depth-graded Mo/Si multilayer coatings for hard x-rays.

This manuscript presents the first systematic study of non-periodic, broadband Mo/Si multilayer coatings with and without B C interface barrier layers for hard x-ray applications with large field of view. The photon energy of operation in this work is 17.4 keV, the Mo Kα emission line.

Trends in self-poisoning and psychotropic drug use in people aged 5-19 years: a population-based retrospective cohort study in Australia.

Objectives: To characterise trends in self-poisoning and psychotropic medicine use in young Australians.

Design: Population-based retrospective cohort study.

Setting: Calls taken by the New South Wales and Victorian Poisons Information Centres (2006-2016, accounting for 70% of Australian poisoning calls); medicine dispensings in the 10% sample of Australian Pharmaceutical Benefits Scheme data (July 2012 to June 2016).

Patterns of poisoning exposure at different ages: the 2015 annual report of the Australian Poisons Information Centres.

Objectives: To characterise the types of calls received by Australian Poisons Information Centres (PICs) in Australia, and to analyse poisoning exposures by age group, circumstances of exposure, and the types of substances involved. Design, setting: Retrospective analysis of call records from all four Australian PICs (national coverage).

Main Outcome Measures: Basic demographic information; exposure circumstances, substance types involved in each age group; recommendations for management (eg, stay at home, go to hospital).

Increasing rates of quetiapine overdose, misuse, and mortality in Victoria, Australia.

Background: Quetiapine is misused due to its anxiolytic and hedonic effects and has been associated with deliberate self-harm. This study analyzed quetiapine-related calls to the Victorian Poisons Information Centre (VPIC), coronial data from Victorian Institute of Forensic Medicine (VIFM) and prescribed data from the Pharmaceutical Benefits Scheme (PBS) to determine current trends in overdose, misuse and mortality.

Methods: This was a retrospective review of multiple databases.

Aperiodic Mo/Si multilayers for hard x-rays.

In this work we have developed aperiodic Molybdenum/Silicon (Mo/Si) multilayers (MLs) to reflect 16.25 keV photons at a grazing angle of incidence of 0.6° ± 0.

A decade of Australian methotrexate dosing errors.

Objective: Accidental daily dosing of methotrexate can result in life-threatening toxicity. We investigated methotrexate dosing errors reported to the National Coronial Information System (NCIS), the Therapeutic Goods Administration Database of Adverse Event Notifications (TGA DAEN) and Australian Poisons Information Centres (PICs).

Design And Setting: A retrospective review of coronial cases in the NCIS (2000-2014), and of reports to the TGA DAEN (2004-2014) and Australian PICs (2004-2015).

Oxycodone/naloxone preparation can cause acute withdrawal symptoms when misused parenterally or taken orally.

Context: Oral oxycodone/naloxone preparations are designed to reduce the incidence of constipation associated with oxycodone use. The low oral bioavailability (< 2%) of naloxone makes the precipitation of the acute opioid withdrawal symptoms unlikely following oral oxycodone/naloxone exposure. The incidence of acute opioid withdrawal symptoms following both oral and intravenous administration of oxycodone/naloxone preparations has not been described.

Triple-wavelength, narrowband Mg/SiC multilayers with corrosion barriers and high peak reflectance in the 25-80 nm wavelength region.

We have developed new, Mg/SiC multilayer coatings with corrosion barriers which can be used to efficiently and simultaneously reflect extreme ultraviolet (EUV) radiation in single or multiple narrow bands centered at wavelengths in the spectral region from 25 to 80 nm. Corrosion mitigation was attempted through the use of Al-Mg or Al thin layers. Three different multilayer design concepts were developed and deposited by magnetron sputtering and the reflectance was measured at near-normal incidence in a broad spectral range.

Development and calibration of mirrors and gratings for the soft x-ray materials science beamline at the Linac Coherent Light Source free-electron laser.

This work discusses the development and calibration of the x-ray reflective and diffractive elements for the Soft X-ray Materials Science (SXR) beamline of the Linac Coherent Light Source (LCLS) free-electron laser (FEL), designed for operation in the 500 to 2000 eV region. The surface topography of three Si mirror substrates and two Si diffraction grating substrates was examined by atomic force microscopy (AFM) and optical profilometry. The figure of the mirror substrates was also verified via surface slope measurements with a long trace profiler.

Metal fume fever - a case review of calls made to the Victorian Poisons Information Centre.

Objective: To determine the epidemiology of metal fume fever over an extended period in Victoria, Australia.

Methods: A retrospective case review of all metal fume fever related calls to the Victorian Poisons Information Centre. Specific defined criteria were used to identify cases of metal fume fever and a set of data points extracted for each.

Hydrofluoric acid poisoning: data from the Victorian Poisons Information Centre.

Objective: To determine the epidemiology of hydrofluoric acid (HF) exposures, over an extended time period, in Victoria, Australia.

Methods: Retrospective case review of all HF exposures from calls to the Victorian Poisons Information Centre (VPIC) from June 2005 to February 2011.

Results: The VPIC received calls regarding 75 separate HF exposures (approximately 12 per year).
