Will Gay and Bisexual Men Taking Oral Pre-exposure Prophylaxis (PrEP) Switch to Long-Acting Injectable PrEP Should It Become Available?

Summary: This study sought to investigate awareness of and preference for using long-acting injectable PrEP (LAI-PrEP) among GBM currently taking oral PrEP (n = 104), and identify their concerns. About half of GBM had heard of LAI-PrEP, and 30.8% specifically preferred LAI-PrEP. GBM with more concerns about the level of protection and drug half-life of LAI-PrEP had lower odds of preferring LAI-PrEP. Oral pre-exposure prophylaxis (PrEP) is highly effective at reducing HIV transmission risk and is CDC recommended for many gay, bisexual, and other men who have sex with men (GBM).The study conc...

Using Registry Data to Construct a Comparison Group for Programmatic Effectiveness Evaluation – the New York City HIV Care Coordination Program.

Summary: This study describes a method to construct a surveillance registry-based comparison group, which allows for estimating the effectiveness of the intervention while controlling for secular trends in the outcome of interest. Using data from the New York City population-based human immunodeficiency virus Surveillance Registry, the study created a contemporaneous comparison group for persons enrolled in the New York City human immunodeficiency virus Care Coordination Program (CCP) from December 2009 to March 2013. Registry-based comparison group estimates were attenuated relative to pre...

Trends in Cannabis and Cigarette Use Among Parents With Children at Home: 2002 to 2015.

Trends in Cannabis and Cigarette Use Among Parents With Children at Home: 2002 to 2015.
Summary: This study investigated trends in cannabis use among parents with children at home in the United States and estimated changes in prevalence of any cannabis use and daily cannabis use among parents who identified as cigarette smokers and nonsmokers with children in the home from 2002 to 2015. Methodology: The National Survey on Drug Use and Health is an annual, nationally representative, cross-sectional study conducted in the United States. Using logistic regression models, associations between cigarette smoking and any past-month and daily past-month cannabis use among parents with...

A non‐linear model for censored and mismeasured time varying covariates in survival models, with applications in human immunodeficiency virus and acquired immune deficiency syndrome studies.

Summary: In applications such as human immunodeficiency virus–acquired immune deficiency syndrome studies, a mechanistic non‐linear model can be derived for the covariate process on the basis of the underlying data generation mechanisms and such a non‐linear covariate model may provide better ‘predictions’ for the censored and mis-measured covariate values. This study proposed a joint Cox and non‐linear mixed effect model to model survival data with censored and mis-measured time varying covariates. The study used likelihood methods for inference, implemented by the Monte Carlo EM algorithm...

Psychosocial characteristics of primary care-seeking long-distance truck drivers in Kenya and associations with HIV testing.

Summary: This study aimed to characterize a sample of 305 truck drivers recruited from 2 roadside wellness clinics in Kenya in terms of anticipated HIV stigma, self-efficacy, fatalism, gender equity, sensation seeking, and self-esteem, and then determine the association of these psychosocial characteristics with HIV testing behavior. Greater general self-efficacy was associated with higher income and more years working as a truck driver. Greater fatalism was associated with non-Christian religion, being married, and having a lower income. Greater gender equity was associated with completing...

Frequency of Cannabis Use and Medical Cannabis Use Among Persons Living With HIV in the United States: Findings From a Nationally Representative Sample.

Summary: This study reviewed cannabis use frequency, medical cannabis use and correlates of use among persons living with HIV (PLWH) in the US nationally representative samples. The study looked at data from 626 PLWH from the 2005-2015 National Survey on Drug Use and Health. Logistic regression identified characteristics associated with frequency of cannabis use. Chi-squares identified characteristics associated with medial cannabis use. Non-daily and daily cannabis use was reported by 26.9% and 8.0%. Greater perceived risk of cannabis use was negatively associated with daily and non-daily ...

Cannabis Use Up Among Parents With Children in the Home

Cannabis Use Up Among Parents With Children in the Home
For immediate release:  May 14, 2018 Study finds combined use of cigarettes and marijuana may increase children’s exposure to second-hand smoke Cannabis use increased among parents who smoke cigarettes, as well as among non-smoking parents, according to a recent study from researchers at ISPH. Cannabis use was nearly four times more common among cigarette smokers compared with non-smokers. Until now, little had been known about current trends in the use of cannabis among parents with children in the home, the prevalence of exposure to both tobacco and cannabis, and which populations might b...

Prevalence of and Factors Associated with the Use of HIV Serosorting and Other Biomedical Prevention Strategies Among Men Who Have Sex with Men in a US Nationwide Survey

Summary: PrEP and treatment-as-prevention (TasP) are biomedical strategies to reduce HIV transmission. Some men who have sex with men (MSM) are combining biomedical strategies with HIV serosorting-termed "biomed matching" when both partners are either on PrEP or TasP, or "biomed sorting" when one partner is using PrEP and the other TasP. The authors of the study expressed there is limited data on the extent of biomed matching/sorting in large geographically diverse samples. In 2016-2017, 5021 MSM from across the US were surveyed about their HIV status and HIV viral load/PrEP use, as well as...
