HIV-1 viral blips are associated with repeated and increasingly high levels of cell-associated HIV-1 RNA transcriptional activity.

Objective: Some HIV+ patients, virally suppressed on ART, show occasional 'blips' of detectable HIV-1 plasma RNA. We used a new highly sensitive assay of cell-associated HIV-1 RNA to measure transcriptional activity in PBMCs and production of infectious virus from the viral reservoir, in patients with and without 'blips'.

Design/methods: RNA and DNA extracted from cells in 6 ml of peripheral blood, from suppressed patients with one to two 'blip' episodes over the past 2 years of ART (n = 55), or no 'blips' (n = 52), were assayed for HIV-1 RNA transcripts and proviral DNA targeting the highly conserved 'R' region of the LTR.

First Complete Genome Sequences of Dengue Virus Serotype 2 Strains from the Solomon Islands and Vanuatu.

Isolates of dengue virus serotype 2 (DENV-2) were recovered from a female resident of the Solomon Islands in 2016 and another female patient who had traveled from Vanuatu to Australia in 2017. Here, we describe the first complete genome sequences of DENV-2 strains from Vanuatu and the Solomon Islands.

Outcomes of telephone-delivered low-intensity cognitive behaviour therapy (LiCBT) to community dwelling Australians with a recent hospital admission due to depression or anxiety: MindStep™.

Background: In 2006, the British government launched 'Improving Access to Psychological Therapies' (IAPT), a low intensity cognitive behaviour therapy intervention (LiCBT) designed to manage people with symptoms of anxiety and depression in the community. The evidence of the effectiveness of IAPT has been demonstrated in multiple studies from the UK, USA, Australia and other countries. MindStep™ is the first adaptation of IAPT in Australia, delivered completely by telephone, targeting people with a recent history of a hospital admission for mental illnesses within the private health system.

Metabolic Profile of Synthetic Cannabinoids 5F-PB-22, PB-22, XLR-11 and UR-144 by Cunninghamella elegans.

The knowledge of metabolic profile of synthetic cannabinoids is important for the detection of drugs in urinalysis due to the typical absence or low abundance of parent cannabinoids in human urine. The fungus Cunninghamella elegans has been reported to be a useful tool for metabolism study and thus applicability to synthetic cannabinoid metabolism was examined. In this study, 8-quinolinyl 1-(5-fluoropentyl)-1H-indole-3-carboxylate (5F-PB-22), 8-quinolinyl 1-pentyl-1H-indole-3-carboxylate (PB-22), [1-(5-fluoropentyl)-1H-indol-3-yl](2,2,3,3-tetramethylcyclopropyl)methanone (XLR-11) and (1-pentyl-1H-indol-3-yl)(2,2,3,3-tetramethylcyclopropyl)methanone (UR-144) were incubated with C.

Highly divergent dengue virus type 1 genotype sets a new distance record.

Dengue viruses (DENVs) are the leading cause of mosquito-borne viral disease of humans. They exist in both endemic and sylvatic ecotypes. In 2014, a viremic patient who had recently visited the rainforests of Brunei returned to Australia displaying symptoms consistent with DENV infection.

Imported zika virus infection from the cook islands into australia, 2014.

A female resident of Townsville, Queensland, Australia has been diagnosed with Zika virus infection following a recent trip to the Cook Islands. An initial serum sample collected in March, 2014 was positive by two separate Zika virus TaqMan real-time RT-PCRs and a pan-Flavivirus RT-PCR. Nucleotide sequencing and phylogenetics of the complete Cook Islands Zika virus envelope gene revealed 99.

Observations from behind the bar: changing patrons' behaviours in response to smoke-free legislation in Scotland.

Background: "Smoke-Free" legislation prohibiting smoking in all enclosed public places was introduced in March 2006. This qualitative study presents insights from bar workers about their observations of the changing social bar environment, changing patrons' behaviours and challenges bar workers have faced in managing smoke-free legislation.

Methods: Twelve in-depth interviews were conducted between November 2006 and January 2007 with a purposively-selected sample of bar workers, identified from a larger quantitative study evaluating the impact of the legislation in Scotland [the Bar Workers' Health and Environmental Tobacco Smoke Exposure project (BHETSE)].
