Determining associations between Big Five personality traits and executive function in an undergraduate student sample.

Objective: The present study sought to determine the associations between executive functioning and Big Five personality traits in an undergraduate sample.

Method: Participants included 200 undergraduates (73% women), with a mean age of approximately 21 years. Participants completed the Big Five Inventory-44 and a psychological assessment battery, which included the Trail Making Test and the Semantic Fluency Test.

Relationship between central autonomic effective connectivity and heart rate variability: A Resting-state fMRI dynamic causal modeling study.

The central autonomic network (CAN) serves as a regulatory hub with top-down regulatory control and integration of bottom-up physiological feedback via the autonomic nervous system. Heart rate variability (HRV)-the time variance of the heart's beat-to-beat intervals-is an index of the CAN's affective and behavioral regulatory capacity. Although neural functional connectivities that are associated with HRV and CAN have been well studied, no published report to date has studied effective (directional) connectivities (EC) that are associated with HRV and CAN.

Differences in internalizing symptoms between those with and without Cannabis Use Disorder among HBCU undergraduate students.

Objective: To determine the differences in internalizing symptoms between those who met criteria for Cannabis Use Disorder (CUD) and those who did not in young adults attending a Historically Black College or University (HBCU).

Participants: The sample included 619 undergraduate students, with 110 (18%) who met criteria for CUD.

Methods: Participants completed an online survey, which included demographic, anxious and depressive symptomatology, and substance use assessment.

Cannabis use disorder severity and sleep quality among undergraduates attending a Historically Black University.

Nearly one third of Americans experience poor sleep, which is associated with numerous deleterious health outcomes. Poor sleep may be exacerbated when an individual attends college, as they experience drastic shifts in lifestyle and sleep patterns. Previous research suggests cannabis has therapeutic potential for sleep disorders but may also impair sleep quality long-term.

Recreational cannabis use is associated with poorer sleep outcomes in young adult African Americans.

Introduction: The present study sought to determine the relationship between self-reported cannabis use dosage in grams per day with (1) objective sleep outcomes: sleep efficiency (SE), sleep onset latency SOL and number of night-time awakenings (NWAK) (2) if objective and subjective sleep measures, using the PSQI, differed between cannabis users and non-cannabis users.

Methods: Our sample included 178 participants, aged 18-35 years. We collected demographic information, cannabis use in dosage per day and frequency of use, depressive symptoms through the CESD, and subjective sleep reports using the PSQI.

Comparison of Cardiorespiratory Fitness in Black or African American Versus Caucasian Patients With Heart Failure.

Purpose: Cardiopulmonary exercise testing (CPX) is a well-established assessment with important insight into prognosis and therapeutic efficacy in patients with heart failure (HF). Prior studies have identified several clinical differences between Black or African American (B-AA) and Caucasian patients with HF. Differences in key CPX responses between these two groups require further investigation.

Assessing the validity of the Self-Report Webexec Questionnaire: Self-report vs performance neurocognitive inferences.

The Webexec is a self-reported neuropsychological measure, which previous research suggests is associated with personality and executive functions. Though the Webexec could be useful for brief neuropsychological assessment, there is limited literature examining its validity. The current study's purpose was to determine Webexec's validity and association with mood symptomatology in two Historically Black College or University (HBCU) undergraduate student samples.

Clinical features and outcomes between African American and Caucasian patients with Takotsubo Syndrome.

Background: Takotsubo syndrome (TS) is an acute, reversible form of heart failure, often mimicking an acute coronary syndrome (ACS). Data regarding racial differences in TS are inconsistent. The aim is to assess clinical features associated with unfavorable in-hospital outcomes between African American (AA) and Caucasian (CAU) patients.

Differences in heart rate among recent marijuana use groups.

Background: Marijuana use increases cardiac sympathetic activity within minutes of its use and this effect may begin to decrease as soon as one hour after marijuana use. However, the cardiovascular effects of marijuana use more than an hour after use is poorly characterized. The purpose of the current study is to compare heart rate, a marker of cardiac sympathetic activity, across recent marijuana use groups (never used: N.

Inverse associations between parasympathetic activity and cognitive flexibility in African Americans: Preliminary findings.

Previous research suggests that vagal activity and executive function (EF) are positively associated. However, existing data exploring the relationship between HRV and EF remains limited. Though Blacks may have higher HRV, they remain underrepresented in previous research examining HRV and EF.

Confirmed marijuana use and lymphocyte count in black people living with HIV.

Background: Marijuana is a commonly used recreational substance with purported analgesic and mood enhancing properties. Many people living with HIV identify marijuana as a palliative substance. However, through its main psychoactive component, tetrahydrocannabinol (THC), is known to influence the immune system.

Self-Reported Lifetime Violence Exposure and Self-Compassion Associated With Satisfaction of Life in Historically Black College and University Students.

In the United States, approximately 25% of minors have witnessed a violent act, specifically physical assault. African Americans from under-served backgrounds are more likely than other racial and ethnic groups to be exposed to traumatic events. However, there is scant literature examining violence exposure, SC, and life satisfaction collectively, specifically in an African American college sample.

Confirmed marijuana use and lymphocyte count in black people living with HIV.

Background: Marijuana is a commonly used recreational substance with purported analgesic and mood enhancing properties. Many people living with HIV identify marijuana as a palliative substance. However, through its main psychoactive component, tetrahydrocannabinol (THC), is known to influence the immune system.

Patterns of Mood and Personality Factors and Associations With STI/HIV-Related Drug and Sex Risk Among African American Male Inmates.

Background: Research on the association between antisocial personality disorder (ASPD) with comorbid mental disorders and sexually transmitted infection (STI)/HIV risk among inmates is scant despite the high prevalence of psychopathology and of STI/HIV in this population.

Methods: We used baseline data from Project DISRUPT, a cohort study conducted among incarcerated African American men (n = 207), to measure associations between ASPD and STI/HIV risk. We also conducted latent class analyses (LCAs) to identify subgroups defined by ASPD with comorbid stress, depression, and borderline personality disorder symptoms and measured associations between latent class membership and STI/HIV risk.

Lifetime marijuana use and sexually transmitted infection history in a sample of Black college students.

Background: Sexually transmitted infections (STIs) and marijuana use are more prevalent in African Americans/Blacks (Blacks) than any other ethnicity in the United States. Given the significant health care costs and deleterious health correlates of using marijuana or contracting a STI, it is imperative to examine their association, especially in the vulnerable and underrepresented group of young adult Blacks.

Purpose: The current study examines the association between lifetime marijuana use on history of STI diagnosis in a sample of Black college students.

Depressive symptomatology and respiratory sinus arrhythmia in a non-clinical sample of middle-aged African Americans.

Decreased heart rate variability and depression are both independent risk factors for cardiac mortality in clinical and non-clinical samples. The purpose of the current study is to examine the hypothesis that severity of depressive symptomatology is inversely associated with respiratory sinus arrhythmia (RSA) in a non-clinical sample of African Americans. The sample included 77 African Americans with a mean age of 48.

Differential effects of self-reported lifetime marijuana use on interleukin-1 alpha and tumor necrosis factor in African American adults.

It is unknown how lifetime marijuana use affects different proinflammatory cytokines. The purpose of the current study is to explore potential differential effects of lifetime marijuana use on interleukin-1 alpha (IL-1α) and tumor necrosis factor (TNF) in a community based sample. Participants included 168 African American adults (51 % female, median age = 47 years).

Association between interleukin-6 and neurocognitive performance as a function of self-reported lifetime marijuana use in a community based sample of African American adults.

The purpose of the current study was to determine if self-reported lifetime marijuana use moderates the relationship between interleukin-6 (IL-6) and neurocognitive performance. Participants included 161 African American adults (50.3% women), with a mean age of 45.

Younger versus older African Americans: patterns and prevalence of recent illicit drug use.

Objectives: The current study examined recent substance use among younger and older African Americans and factors associated with recent use.

Methods: The current study used a subset of African American men and women (N = 260) from the NEURO-HIV Epidemiological Study (Mage = 42, SD = 9.27; 59% female).

Binge drinking, stimulant use and HIV risk in a sample of illicit drug using heterosexual Black men.

Background: Relatively little research has examined the effects of binge drinking and HIV risk in heterosexual Black men. Even less research has explored this relationship in illicit drug using heterosexual Black men who are at an elevated risk of contracting and transmitting HIV through various vectors, including risky sexual behavior, in the Black community.

Purpose: The purpose of the current study is to examine the associations between binge drinking, drug use and HIV status in a community-based sample of 127 self-identified heterosexual Black men.

Injection and non-injection drug use and infectious disease in Baltimore City: differences by race.

Purpose: The current study examines differences in the prevalence of biologically-confirmed hepatitis C virus (HCV), HIV, and coinfection between Black and White adult cocaine/heroin users across three drug use subgroups identified in previous research (Harrell et al., 2012): non-injection smoking crack/nasal heroin users, heroin injectors, and polydrug injectors.

Results: 59% of the 482 participants in the study were male.
