Nondaily cigarette smoking up among those with mental health and substance use problems; daily smoking continues to decline overall.

Nondaily cigarette smoking up among those with mental health and substance use problems; daily smoking continues to decline overall.
For immediate release: November 8, 2018 Study finds persistent discrepancies in cigarette smoking between those with mental health and substance use problems and those without Between 2005 and 2014, nondaily cigarette use increased among persons with common mental health and substance use problems (MHSUP), according to a new study in The Journal of Clinical Psychiatry lead by Renee Goodwin, Deputy Director of the Institute for Implementation Science in Population Health. “Historically, non-daily or infrequent smoking was not considered a great concern, and attention was focused primarily...

CUNY ISPH investigators help define subtypes of ovarian cancer

CUNY ISPH investigators help define subtypes of ovarian cancer
September 4, 2018 In a new paper published in the journal Clinical Cancer Research, CUNY SPH Associate Professor Levi Waldron and colleagues resolved the long-standing controversy over how to define molecular subtypes of high-grade serous ovarian carcinoma, the most common form of ovarian cancer and the fifth leading cause of cancer deaths in the United States. Understanding molecular subtypes of common forms of cancer is important because clinically similar cases may differ in their genetic underpinnings, causes, and outcomes. “Lumping together potentially different diseases just bec...

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 ...
