Conscientious Objection and Institutional Objection to Voluntary Assistance in Dying: An Ethico-legal Critique.

This column examines conscientious objection and institutional objection in Australian voluntary assistance in dying. It reviews the current legislative regimes and then examines these practices from an ethical perspective, and raises particular concerns and suggestions with how conscientious objection and institutional objection should be operationalised.

Reducing unnecessary testing on sputum specimens from patients with cystic fibrosis: pathology stewardship in microbiology.

Chronic respiratory tract infection by Pseudomonas aeruginosa is the hallmark of established lung disease in patients with cystic fibrosis (CF). Antibiotic therapy can usually only suppress but not eradicate infection. In recent years, pulmonary infection with non-tuberculous Mycobacteria (NTM) species has also been increasing.

Nocturnally pruritic rash.

Quick thinking and fast reflexes during the physical exam led to an identification that confirmed the diagnosis.

Discovery of GSK251: A Highly Potent, Highly Selective, Orally Bioavailable Inhibitor of PI3Kδ with a Novel Binding Mode.

Optimization of a previously reported lead series of PI3Kδ inhibitors with a novel binding mode led to the identification of a clinical candidate compound (GSK251). Removal of an embedded Ames-positive heteroaromatic amine by reversing a sulfonamide followed by locating an interaction with Trp760 led to a highly selective compound . Further optimization to avoid glutathione trapping, to enhance potency and selectivity, and to optimize an oral pharmacokinetic profile led to the discovery of compound (GSK215) that had a low predicted daily dose (45 mg, b.
