Adults with cancer may perceive cannabis as beneficial for managing their cancer-related symptoms, but the evidence supporting its medical use is varied and inconclusive. This study characterized associations of cannabis use with cancer-related symptom trajectories. Participants were adults undergoing cancer treatment at the Stephenson Cancer Center (SCC; n = 218) in Oklahoma; they were 71% female, 10% minoritized race, and 45% had stage III or IV cancer.

Background: Prostate cancer is the most diagnosed cancer in Black/African American men (AA) and the second‑leading cause of cancer-related deaths. A prostate-specific antigen (PSA) blood test is an early detection screening tool for prostate cancer, but uptake of PSA screening remains low among AA men. Greater PSA screening rates among AA men, coupled with earlier treatment, may reduce disparities in prostate cancer outcomes, including mortality.

Article Synopsis
  • The study investigates economic disparities in tobacco use among high school students, using data from 6750 individuals surveyed in Spring 2021.
  • It finds that experiencing homelessness significantly increases the likelihood of using various tobacco products, while food insecurity is linked to current use but not daily use.
  • The research emphasizes the need for interventions that address economic factors related to tobacco use during adolescence, particularly focusing on preventing tobacco use and tackling issues like homelessness and food insecurity.

Article Synopsis
  • Persistent Poverty Counties (PPCs) in the U.S. have high cancer mortality rates, partly due to high smoking rates, with this study focusing on Oklahoma Tobacco Helpline (OTH) participants who smoke daily.
  • The study used a randomized controlled trial design to evaluate the effectiveness of OTH treatments versus OTH treatments combined with financial incentives (OTH+FI) to help participants quit smoking.
  • Results showed that those in the OTH+FI group were significantly more likely to achieve smoking abstinence and complete more coaching calls compared to the standard OTH group, with high retention rates noted across both groups.

Background: Little is known about the risks and benefits of cannabis use in the context of cancer care. This study characterized the prevalence, reasons for use, and perceived benefits of cannabis and compared symptoms and perceived risks between those who reported past 30-day cannabis use and those who did not.

Methods: Adults undergoing cancer treatment at a National Cancer Institute-designated cancer center completed measures of sociodemographic characteristics, cannabis use, use modalities, reasons for use, perceived harms/benefits of use, physical and psychological symptoms, and other substance/medication use.

Introduction: The influence of culture on body mass index (BMI) and obesity within the African American population is an underexplored area in the literature. Therefore, this study explored the extent to which cultural identity was associated with BMI and obesity among African Americans and whether the association of cultural identity with obesity differed between males and females.

Methods: Participants were African Americans (n = 304) who responded to an online survey.

Background And Objectives: Oklahoma has a fast-growing medical cannabis industry, showing a proliferation of industry marketing. While cannabis marketing exposure (CME) is a risk factor for cannabis use and positive attitudes about use, no studies have examined the impact of CME on attitudes and use behavior in a permissive cannabis policy environment, like Oklahoma.

Methods: N = 5428 Oklahoma adults ages 18 and older completed assessments of demographics, past 30-day cannabis use, and past 30-day exposure to each of four types of cannabis marketing: outdoor (billboards, signs), social media, print (magazines), and Internet.

Introduction: Discrimination experiences may be a contributing factor to the elevated prevalence of mental health problems among adults experiencing homelessness.

Methods: Using survey data (N = 552) collected from adults seeking services at an urban day shelter, the relationships between everyday and major discrimination experiences, distress tolerance, and mental health problems (depression, anxiety, post-traumatic stress disorder, poor mental health days) were characterized. Distress tolerance was examined as a moderator of the relationship between discrimination and mental health problems.

Background: Digital smoking cessation interventions may reduce racial disparities in cessation because they are low cost, scalable, and can provide support at any place or time. Despite their promise, whether Black adults engage with and benefit from these tools is largely unknown. In a secondary analysis of a randomized trial, we explored the efficacy of an acceptance and commitment therapy (ACT)-based website (WebQuit) for smoking cessation compared to a US clinical practice guidelines-based website (Smokefree.

This study investigated the relationship between concussions and medication adherence among 247 adults experiencing homelessness in Oklahoma City, Oklahoma, who were prescribed medication for a psychiatric disorder. Participants were asked whether they had "ever experienced a blow to the head that caused a concussion," and medication adherence was measured by asking participants whether they had taken their psychiatric medication yesterday. The data were analyzed using univariate and multivariable logistic regressions.

Background: Sexual and gender minority (SGM) adults are overrepresented in the population of individuals experiencing homelessness, and high rates of substance use are common in this group. Plausibly, poor mental health and discrimination may contribute to substance use among SGM adults experiencing homelessness. This study described participant characteristics, and the interrelations among sociodemographic variables, substance use, mental health, and discrimination experiences among 87 SGM adults seeking services at a day shelter in Oklahoma City, OK.

There are racial disparities in the outcome of triple negative breast cancer (TNBC) patients between women of African ancestry and women of European ancestry, even after accounting for lifestyle, socioeconomic and clinical factors. MicroRNA (miRNA) are non-coding molecules whose level of expression is associated with cancer suppression, proliferation and drug resistance; therefore, these have potential for biomarker applications in cancers including TNBC. Historically, miRNAs up-regulated in African American (AA) patients have received less attention than for patients of European ancestry.

Background: Few studies have examined how daily adherence to nicotine replacement therapy (NRT) impacts daily smoking abstinence.

Methods: Data from a pilot randomized controlled trial of a smartphone-based smoking cessation intervention were used. Separate, generalized linear mixed models examined the association between ecological momentary assessments of NRT use and same-day and next day smoking status.

Introduction: Menthol cigarettes are popular among young adults and are disproportionately used by African American smokers. Menthol's minty and cooling sensations have been hypothesized to enhance the appeal and reinforcement of smoking; however, differences in menthol's subjective appeal across races have been inconsistent. This secondary data analysis examined differences in subjective appeal for smoking menthol versus non-menthol cigarettes between African American and White young adult smokers.

The current study investigated whether stressful life events and everyday discrimination experiences were associated with using one or more substances in the past 30-days and substance use disorder (SUD) among adults experiencing homelessness. We obtained survey data from adults (N = 501) seeking services at a day shelter. Participants self-reported whether they used cigarettes, other tobacco products, cannabis, alcohol, opioids, amphetamine, and cocaine/crack in the past 30-days, and the total number of substances used were also calculated.
