Head computed tomography for elderly patients with acute altered mental status in the emergency setting: value for decision-making and predictors of abnormal findings.

Objective: This study evaluated the impact of head computed tomography (CT) on clinical decision-making about older adults with acute altered mental status (AMS) in the emergency department in terms of CT's diagnostic yield, emergency department length of stay, and changes in medical strategy. It also attempted to find predictors of an acute imaging abnormality.

Methods: This was a 1-year, retrospective, single-center observational study of patients aged ≥75 years who underwent noncontrast head CT because of an isolated episode of AMS.

Supporting the mental health of children with speech, language and communication needs: The views and experiences of parents.

Background And Aims: A high rate of children in mental health services have poor language skills, but little evidence exists on how mental health support is delivered to and received by children with language needs. This study looked at parental experiences, asking parents of children with speech, language and communication needs (SLCN) about their experiences seeking help for their children's mental health. We were particularly interested on the experiences of parents of children with Developmental Language Disorder (DLD), a specific SLCN that remains relatively unknown to the general public.

Ethical position of medical practitioners who refuse to treat unvaccinated children.

Recent reports in Australia have suggested that some medical practitioners are refusing to treat children who have not been vaccinated, a practice that has been observed in the USA and parts of Europe for some years. This behaviour, if it is indeed occurring in Australia, has not been supported by the Australian Medical Association, although there is broad support for medical practitioners in general having the right to conscientious objection. This paper examines the ethical underpinnings of conscientious objection and whether the right to conscientious objection can be applied to the refusal to treat unvaccinated children.

Carbonyl complexes of platinum(0): synthesis and structure of [(Cy3P)2Pt(CO)] and [(Cy3P)2Pt(CO)2].

The platinum(0) monocarbonyl complex, [(Cy(3)P)(2)Pt(CO)], was synthesized by reaction of [(Cy(3)P)(2)Pt] with [(η(5)-C(5)Me(5))Ir(CO)(2)] and subsequent irradiation. X-ray structure analysis was performed and represents the first structural evidence of a platinum(0) monocarbonyl complex bearing two free phosphine ligands. Its corresponding dicarbonyl complex [(Cy(3)P)(2)Pt(CO)(2)] was synthesized by treatment of [(Cy(3)P)(2)Pt] with CO at -40 °C and confirmed by X-ray structure analysis.

Synthesis, structure, and bonding of novel homodinuclear cobalt and nickel borylene complexes.

Herein we report for the first time full details on the synthesis and structural characterization of novel homodinuclear bridging cobalt and nickel borylene complexes containing bridging carbonyl ligands, an unusual coordination motif rarely before observed for homodinuclear borylene complexes. Furthermore, the homodinuclear nickel complex represents the first instance of a nickel borylene complex. Quantum chemical analyses of charge-density topology, electron localization function (ELF) and natural charges indicate the absence of direct metal-metal bonds in both the cobalt and nickel systems, in contradiction with electron counting.

Synthesis and structure of heterodinuclear rhodium and iridium borylene complexes.

Herein we report on the synthesis and structural characterization of a representative range of novel heterodinuclear bridging rhodium and iridium borylene complexes. The iridium borylene complexes feature an unusual coordination mode of the borylene ligand. Furthermore, the first instance of a heterodinuclear-bridged borylene compound containing a chromium atom in the three-membered ring is reported.
