Background: Heavy drinking, smoking, and depression are common among men who have sex with men (MSM). The association of co-occurring longitudinal patterns of these conditions and mortality among MSM were tested, applying a syndemic framework - the interaction of two or more conditions that contribute to poor health outcomes.

Methods: Longitudinal data from 1999 to 2018 from the Multicenter AIDS Cohort Study of 3046 MSM were analyzed.

Background: A minority of people who need alcohol treatment receive it. Unhealthy alcohol use is common among people with HIV (PWH) and can lead to negative health outcomes. The aims of this multi-methods study are to (1) quantitatively describe the prevalence, psychosocial characteristics, and demographic traits of a sample of PWH currently receiving HIV care in Florida who had a self-reported need for alcohol treatment but did not seek care and (2) qualitatively explore reasons why PWH did not seek treatment.

On December 8th 2023, the annual Alcohol and Immunology Research Interest Group (AIRIG) meeting was held at the University of Colorado Anschutz Medical Campus in Aurora, Colorado. The 2023 meeting focused broadly on how acute and chronic alcohol exposure leads to immune dysregulation, and how this contributes to damage in multiple tissues and organs. These include impaired lung immunity, intestinal dysfunction, autoimmunity, the gut-Central Nervous System (CNS) axis, and end-organ damage.

Article Synopsis
  • A study called the St PETER HIV trial explored how abstaining from alcohol and tobacco affects mental health in people with HIV, involving 400 participants in Russia.
  • The researchers looked at the relationship between 30-day point prevalence abstinence (PPA) from alcohol and/or smoking and symptoms of anxiety and depression over 1, 3, 6, and 12 months using established mental health scales.
  • While initial analyses didn't find strong differences in mental health between groups over time, some patterns in depressive symptoms were noted, suggesting more research is needed, especially with larger sample sizes and longer periods of abstinence.

Article Synopsis
  • Mental health issues and substance use interact, creating psychosocial syndemics that worsen health outcomes for sexual minority men (SMM).
  • A study with 3,384 SMM identified four groups: "poly-behavioral," "smoking and depression," "illicit drug use," and "no conditions," with many remaining in their initial class over time.
  • SMM experiencing complex issues, like illicit drug use, are less likely to improve and may require specialized public health interventions and better access to treatment resources.

Article Synopsis
  • Heavy drinking, smoking, and depression are common among women with HIV, but the long-term effects of having multiple conditions at once on mortality are not well understood.
  • This study analyzed data from over 3,000 women with HIV to investigate the relationship between these conditions and mortality risks, finding that nearly 17% had two or more conditions.
  • Women with multiple risk factors had a significantly higher all-cause mortality risk (almost 4 times greater compared to those with none), highlighting the necessity for coordinated treatment and screening for these interconnected health issues.*

We assessed whether tobacco screening provides clinically meaningful information about other substance use, including alcohol and other drug use, potentially facilitating targeting of screening for substance use. Using data from the Veterans Aging Cohort Study survey sample (VACS; N = 7510), we calculated test performance characteristics of tobacco use screening results for identification of other substance use including sensitivity, specificity, positive-likelihood-ratio (+LR = [sensitivity/(1-specificity)]: increase in odds of substance use informed by a positive tobacco screen), and negative-likelihood-ratio (-LR: [(1-sensitivity)/specificity]: reduction in odds of substance use informed by a negative tobacco screen). The sample was 95% male, 75% minority, and 43% were current and 33% were former smokers.

Unhealthy alcohol use, smoking, and depressive symptoms are risk factors for cardiovascular disease (CVD). Little is known about their co-occurrence - termed a syndemic, defined as the synergistic effect of two or more conditions-on CVD risk in people with HIV (PWH). We used data from 5621 CVD-free participants (51% PWH) in the Veteran's Aging Cohort Study-8, a prospective, observational study of veterans followed from 2002 to 2014 to assess the association between this syndemic and incident CVD by HIV status.

Background: We aimed to investigate the impact of reducing drinking in patients with unhealthy alcohol use on improvement of chronic pain interference, substance use, and psychiatric symptoms.

Methods: We analyzed longitudinal data from 2003 to 2015 in the Veterans Aging Cohort Study, a prospective, multisite observational study of US veterans, by emulating a hypothetical randomized trial (a target trial). Alcohol use was assessed using the Alcohol Use Disorders Identification Test (AUDIT) questionnaire, and outcome conditions were assessed via validated survey items.

Objective: We sought to quantify the extent to which a depression screening instrument commonly used in primary care settings provides additional information regarding pain interference symptoms, anxiety, and substance use.

Methods: Veterans Aging Cohort Study (VACS) data collected from 2003 through 2015 was used to calculate odds ratios (OR) for associations between positive depression screening result cutoffs and clustering conditions. We assessed the test performance characteristics (likelihood ratio value, positive predictive value, and the percentage of individuals correctly classified) of a positive Patient Health Questionnaire (PHQ-9 & PHQ-2) depression screen for the identification of pain interference symptoms, anxiety, and substance use.

Despite campaigns to increase safer sex practices, there are people living with HIV/AIDS (PLWH) who do not disclose their HIV status to sexual partners and engage in condomless sex. The purpose of this research was to: 1) describe factors associated with disclosure of HIV status to sexual partners; and 2) determine if disclosure and/or receipt of prevention counseling are independently associated with condomless sex. We used the Florida Medical Monitoring Project to analyze data from 376 HIV positive men with more than one sexual partner.
