The alkaloid inducamide C is proposed to contain a very rare benzoxazepine ring. Herein, we report that the benzoxazepine ring in inducamide C is unstable and prone to rearrangement, indicating that structural revision of the natural product may be necessary. In a first-generation synthetic approach, attempts to assemble the benzoxazepine by cyclization of 4-hydroxyinducamide A led to the regioisomeric oxepanoindole, a result of the 4-hydroxyindole (C4-OH) undergoing preferential cyclization instead of the desired chlorosalicylic acid C15-OH.

The study involved a 6-month pilot of a locally developed evidence-based screening algorithm in a remote Western Australian Kimberley town. A retrospective audit of electronic health records for the pilot period (27 June-26 December 2016) and a 6-month period before the screening algorithm was introduced (1 October 2015-31 March 2016) was conducted.

Semi-structured interviews formulated by Aboriginal Health Workers, researchers and other clinicians were used to obtain qualitative data from 13 adult Aboriginal patients with type 2 diabetes managed in two remote communities in the Kimberley. Together with expert opinion from local Aboriginal Health Workers and clinicians, the information was used to develop strategies to improve diabetes management.

N-heterocyclic carbene (NHC) catalyzed reactions, in which β-unsubstituted conjugate acceptors undergo homoenolate formation and C-C bond formation twice, have been developed. Specifically, the all-carbon (5+1) annulations give a range of mono- and bicyclic cyclohexanones (31 examples).

Herein we report the cycloisomerization of electron-poor 1,5-dienes via the β-azolium ylide to give enantioenriched cyclopentenes. The reaction is mediated by a chiral N-heterocyclic carbene (NHC) catalyst, exploits readily available substrates, has good generality (17 examples), and displays excellent enantioselectivity (mostly >94:6). Studies demonstrating the viability of a related dynamic kinetic resolution are reported, as are those with alternate tethers and derivatizations.

DESIGN: Retrospective cohort study and audit of remote adult bronchiectasis hospital admissions between 2011 and 2016.
Setting: Remote hospital inpatients.
The inducamides are a family of chlorinated alkaloids featuring an amide arising from union of an l-tryptophan to a rare chlorosalicylic acid unit, the production of which is linked to a chemically induced mutation in the RNA polymerase of Streptomyces sp. (SNC-109-M3). The synthesis of inducamides A and B has been accomplished by the coupling of 6-hydroxy-3-chloro-2-methylbenzoic acid with l-6-chlorotryptophan and l-tryptophan, respectively, followed by ester hydrolysis.

Objective: This study sought to explore the mental health literacy of adolescents living in a rural area in Australia through in-depth, semi-structured interviews, with a view to identifying areas for further research and making recommendations for improved education programs around mental health.
Method: Nine Year 10 students (two boys and seven girls) from a rural secondary school in South Australia read two vignettes, one portraying depression and the other schizophrenia. Semi-structured individual interviews that focussed on the vignettes were audio-taped, transcribed and analysed for thematic content.

Context: Australian university rural health clubs (RHC) are part of a national strategy to address the rural health workforce shortage. The student members of these clubs throughout Australia comprise the National Rural Health Network (NRHN). The NRHN is a multidisciplinary body representing medical, nursing and allied health students, aiming to increase the health workforce and health outcomes for rural and remote Australians.

Our review revealed no studies, to date, that have evaluated the effects of parental substance abuse on reports of chronic pain and coping in adult patients with sickle cell disease (SCD). We explored the effects of parental substance (alcohol or drug) abuse on reports of the sensory, affective and summary indices of pain in 67 adult patients, mean age 38.
