Direct acting antivirals (DAAs) have revolutionized management of hepatitis C virus (HCV), but treatment uptake remains low among persons who inject drugs (PWID). We report the continuum of care for HCV and describe predictors of treatment with DAAs among PWID in Seattle.

We analyzed data from the 2018 Seattle area National HIV Behavioral Surveillance (NHBS) survey of PWID. Persons ≥18 years of age who injected drugs in the past year and completed the core NHBS survey, a local survey supplement, and rapid HCV antibody testing were included. Among those who screened HCV antibody positive, we calculated proportions and 95 % confidence intervals for self-reported steps along the HCV care continuum. Multivariable logistic regression was used to calculate the adjusted odds (AOR) of having received DAA therapy.

The sample included 533 PWID, 376 (71 %) of whom tested positive for antibodies to HCV. Among those who were HCV antibody positive, 94 % reported any prior HCV test, 81 % reported a prior confirmatory test, and 68 % reported a prior HCV diagnosis. Of those diagnosed, 26 % had undergone treatment and 18 % had been cured. In a multivariate model, being one year older (AOR 1.05 per year, 1.01-1.08) was predictive of DAA treatment, while homelessness (AOR 0.39, 0.19-0.80) and female gender (AOR 0.36, 0.16-0.78) were associated with a lower odds of DAA therapy.

Despite widespread HCV testing among PWID in Seattle, treatment uptake remains low in the DAA era. In particular, treatment of women, younger adults and persons living homeless is lagging behind.

Exercise is increasingly being used in the treatment of alcohol use disorder (AUD). We examined the short-term effects of acute exercise on alcohol craving, mood states and state anxiety in physically inactive, non-treatment seeking adults with AUD.

Exploratory, single-arm study. In total, 140 adults with AUD (53.7 ± 11.8 years; 70 % female) were included in a randomized controlled trial (RCT) to study effects of physical activity on alcohol consumption. This acute exercise study was nested within the larger RCT. The intervention was a 12-minute sub-maximal fitness test performed on a cycle ergometer. Participants self-rated their desire for alcohol (DAQ) and completed mood (POMS-Brief) and state anxiety (STAI-Y1) questionnaires 30-minutes before exercise, immediately before, immediately after, and 30-minutes post. Ratings of perceived exertion (RPE) were collected. Effects of exercise were assessed using RM-ANOVA and dependent sample t-tests with effect sizes (Hedges g).

In total, 70.6 % had mild or moderate AUD (DSM-5 criteria = 4.9 ± 2). MDL-800 molecular weight The intervention was generally perceived as 'strenuous' (RPE = 16.1 ± 1.6). In the total sample, there was a main effect of time with reductions in alcohol craving [F(3,411) = 27.33, p < 0.001], mood disturbance [F(3,411) = 53.44, p < 0.001], and state anxiety [F(3,411) = 3.83, p = 0.013]. Between-group analyses indicated larger magnitude effects in those with severe compared to mild AUD, however, AUD severity did not significantly moderate the within-group improvements group x time interaction for alcohol craving [F(6,411) = 1.21, p = 0.305]. Positive effects of exercise were maintained 30-minutes post-exercise.

A short bout of aerobic exercise reduced alcohol craving and improved mood states in adults with AUD.

Illegally manufactured potent synthetic opioids (IMPSO) like fentanyl have contributed to rises in overdose deaths in parts of North America and Europe. While many of these substances are produced in Asia, there is little evidence they have entered markets there. We consider the susceptibility to IMPSO's encroachment in markets in the Asia-Pacific region.

Our analysis focuses on Australia, China, India, and Myanmar. Using a mixed-methods approach comprising interviews, literature review, and secondary data analyses, we examine factors facilitating or impeding incursion of IMPSO. Finally, we illustrate the potential for IMPSO fatalities in Australia.

Australia reports some signs of three facilitating factors to IMPSO's emergence 1) existing illicit opioid markets, 2) disruption of opioid supply, and 3) user preferences. The other three countries report only existing illicit opioid markets. While diverted pharmaceutical opioids are a noted problem in Australia and India, heroin is the dominant opioid in all four countries. There are divergent trends in heroin use, with use declining in China, increasing in India, and stable in Australia and Myanmar. If IMPSO diffused in Australia as in North America from 2014 to 2018, and our assumptions generally hold, deaths from IMPSO could range from 1500-5700 over a five-year period.

This analysis and illustrative calculations serve as an early indication for policymakers. With the exception of Australia, many countries in the region fail to properly record overdose deaths or monitor changes in local drug markets. Early assessment and monitoring can give officials a better understanding of these changing threats.

However, the steroidal structure of PR antagonists could bind to other hormone receptors, thus leading to serious side effects. On the other hand, non-steroidal PR antagonists have rarely been evaluated for their anti-cancer efficacy. Therefore, identifying novel non-steroidal PR antagonists possessing potent anti-cancer efficacy would be an attractive project to pursue. In this study, we presented a new metal-free oxidative CH arylation method to rapidly synthesize a series of 6-aryl-6H-benzo[c]chromene derivatives. Multiple cancer cell lines were used for their anti-cancer activity screening. An extensive analysis of structure-activity relationships (SAR) of the derivatives revealed that compounds 32 and 34 markedly inhibited the proliferation of MCF-7 cells with IC50 values of 6.32 ± 0.52 μM and 5.71 ± 0.49 μM, respectively. Further investigation indicated that derivatives 32 and 34 could elevate the expression of p21 and decrease the expressions of CDK4 and cyclin D1, leading to cell cycle arrest at G0/G1 phase.
